(1) This registration statement relates to securities of the registrant
exchangeable for shares of common stock, par value $1.00 per share, of
Litton Industries, Inc., a Delaware corporation, (together with the
associated rights to purchase preferred stock of Litton pursuant to the
Rights Agreement dated as of August 17, 1994 between Litton and The Bank
of New York, as amended as of December 21, 2000 and January 23, 2001, the
"Litton common stock") in the offer to purchase or exchange by registrant
for all of the issued and outstanding shares of Litton common stock and
all of the issued and outstanding shares of Series B $2 Cumulative
Preferred Stock of Litton (the "Litton preferred stock") pursuant to the
Amended and Restated Agreement and Plan of Merger (the "amended merger
agreement") dated as of January 23, 2001 among Northrop Grumman
Corporation, Litton, NNG, Inc. and LII Acquisition Corp.

(2) The registration fee has been determined pursuant to Rule 457(c) and (f)
of the Securities Act of 1933, as amended, (the "Securities Act"), based
on the average of the high and low sales prices for the shares of Litton
common stock as reported on the New York Stock Exchange ("NYSE") on
January 26, 2001 ($78.78), and the estimated maximum number of shares of
Litton common stock (18,641,387) that may be exchanged for NNG common
stock and NNG Series B Preferred Stock registered herein. Pursuant to
Rule 457(f)(3), the fee is based on: (i) the total number of shares of
Litton common stock outstanding as of December 31, 2000 (45,577,834), plus
(ii) options to purchase 1,244,523 shares of Litton common stock
outstanding as of December 31, 2000, less (iii) the estimated amount of
cash consideration to be paid for the shares of Litton common stock in the
offer. The fee amount is calculated as follows: [(46,822,357 x $78.78) -
((46,822,357 - 18,641,387) x $80.00)] x 0.000250 = $358,546.92.

(3) In accordance with Rule 457(b), the fee described above in footnote (2)
has been offset by the amount previously paid ($767,819.11) pursuant to
Rule 0-11(b) of the Securities Exchange Act of 1934, as amended, (the
"Exchange Act"), in connection with the Schedule TO Filed with the SEC on
January 5, 2001. As provided in Rule 0-11(a)(2), only "one fee per
transaction" is required to be paid. Accordingly, no additional fee is
due.

(4) The registration fee of $358,546.92 is the total registration fee for both
the NNG common stock and the NNG Series B Preferred Stock.

Each Outstanding Share of Common Stock
(together with associated rights)
of
LITTON INDUSTRIES, INC.
for
any of the following, at the election of tendering holders of common stock
$80.00 net per share, in cash, not subject to proration
or
$80.25 in market value (determined as described below) of shares of
NNG, Inc. Common Stock, subject to proration
or
0.80 shares of NNG, Inc. Series B Preferred Stock, subject to proration
and

$35.00 net per share, in cash, not subject to proration
by
NNG, INC., a wholly-owned subsidiary
of
NORTHROP GRUMMAN CORPORATION

NNG, Inc. (the initials stand for "New Northrop Grumman") is a newly-
organized corporation which will become the parent holding company for Northrop
Grumman Corporation immediately prior to the purchase of Litton shares in the
offer. At such time, NNG, Inc. will change its name to "Northrop Grumman
Corporation" and the present Northrop Grumman Corporation will change its name
to "Northrop Grumman Operations Corporation."

The offer and withdrawal rights will expire at 12:00 Midnight, New York City
time, on Thursday, March 1, 2001 unless extended. Shares of Litton common stock
and Litton preferred stock tendered pursuant to the offer may be withdrawn at
any time prior to the expiration of the offer and, unless previously accepted
for purchase or exchange pursuant to the offer, may also be withdrawn at any
time after Tuesday, March 6, 2001.

The offer is made pursuant to an Amended and Restated Agreement and Plan of
Merger, dated as of January 23, 2001 (referred to as the "amended merger
agreement"), among Northrop Grumman Corporation, Litton Industries, Inc., NNG,
Inc. and LII Acquisition Corp. The board of directors of Litton has approved
and deemed advisable the amended merger agreement, the offer and the merger of
LII Acquisition with and into Litton (referred to as the "Litton merger"),
determined that the offer is fair to, and in the best interests of, holders of
Litton common stock and recommends that holders of Litton common stock accept
the offer and tender their Litton common stock pursuant to the offer. The
Litton board of directors makes no recommendation with respect to the tender of
the Litton preferred stock.

The number of shares of NNG common stock to be exchanged for each share of
Litton common stock for which a tendering holder elects to receive NNG common
stock will be determined by dividing $80.25 by the average of the closing
prices of Northrop Grumman common stock on the New York Stock Exchange ("NYSE")
for the five consecutive trading days ending on the second trading day before
the expiration of the offer.

There is no limit on the number of shares of Litton common stock or Litton
preferred stock that may be exchanged for cash in the offer and consequently
the cash consideration offered will not be subject to proration. Subject to
NNG's option (described below) to substitute cash for shares of NNG common
stock in certain circumstances, the maximum number of shares of NNG common
stock that will be issued in the offer is 13,000,000 (referred to as the
"maximum common stock consideration"), and the maximum number of shares of NNG
preferred stock that will be issued in the offer is 3,500,000 (referred to as
the "maximum preferred stock consideration"). Therefore, elections to receive
NNG common stock and NNG preferred stock will be subject to proration if
holders of Litton common stock request in the aggregate more than the maximum
amount of such consideration available. Holders of Litton preferred stock may
exchange their Litton preferred stock only for cash.

The offer is subject to the conditions listed under "The Offer--Conditions of
the Offer," including, that there be validly tendered and not withdrawn prior
to the expiration of the offer a total of at least 25,646,399 shares of Litton
common stock and Litton preferred stock (referred to as the "minimum tender
condition"). After the consummation of the offer, NNG common stock will trade
on the NYSE under the symbol "NOC." NNG will seek to list the NNG preferred
stock on the NYSE if there are enough holders to satisfy NYSE listing
requirements. The Litton common stock and the Litton preferred stock currently
trade on the NYSE and the Pacific Exchange under the symbols "LIT" and "LIT.B,"
respectively.

See "Important Considerations Concerning Elections to Receive NNG Stock"
beginning on page 11 for a discussion of certain factors that holders of Litton
common stock should consider in connection with the offer.

----------

Neither the Securities and Exchange Commission nor any state securities
commission has approved or disapproved of these securities or passed upon the
adequacy or accuracy of this offer to purchase or exchange. Any representation
to the contrary is a criminal offense.

The date of this offer to purchase or exchange is February 1, 2001

Northrop Grumman. Its principal executive offices are located at 1840 Century
Park East, Los Angeles, California 90067 and its telephone number is (310) 553-

the Northrop reorganization described below and has not conducted any business
activities to date. As a result of the Northrop reorganization and after the
consummation of the offer, Northrop Grumman and Litton will become subsidiaries
of NNG. Accordingly, the business of NNG will consist of the business currently
conducted by Litton and Northrop Grumman.

The Northrop Reorganization

Immediately prior to NNG purchasing Litton common stock and Litton preferred
stock in the offer, Northrop Grumman will be reorganized. Currently, NNG has
two wholly-owned subsidiaries, NGC Acquisition Corp. and LII Acquisition Corp.,
as illustrated below:

[GRAPHIC APPEARS HERE]

NGC Acquisition Corp. and LII Acquisition Corp. are newly-formed Corporations
which were organized for the purpose of the transactions described herein.

In the Northrop reorganization, immediately prior to the purchase of Litton
common stock and Litton preferred stock in the offer, NGC Acquisition will
merge with and into Northrop Grumman. As a result,

Northrop Grumman will become a wholly-owned subsidiary of NNG. NNG will change
its name to "Northrop Grumman Corporation," and, Northrop Grumman will be
renamed "Northrop Grumman Operations Corporation." All of Northrop Grumman's
capital stock will be converted into capital stock of NNG. The outstanding
shares of Northrop Grumman common stock will automatically be deemed to be
outstanding shares of NNG common stock with no exchange of certificates and
the NNG common stock will have the same rights, preferences and privileges as
the Northrop Grumman common stock. The NNG common stock will be publicly
traded and listed on the NYSE. The following chart illustrates the resulting
corporate structure:

[GRAPHIC APPEARS HERE]

The Litton Merger

Following NNG's purchase of Litton common stock and Litton preferred stock
in the offer, LII Acquisition will merge with and into Litton. At the
effective time of the Litton merger, each outstanding share of Litton common
stock, except for shares held by dissenting Litton stockholders, NNG, Litton
or their subsidiaries, will be converted into the right to receive $80.00 in
cash, and each outstanding share of Litton preferred stock will remain
outstanding without any change.

Choices Available to Litton Stockholders

Holders of Litton common stock who desire to tender their shares in the
offer may select one of the following forms of payment for each of their
shares of Litton common stock:

. $80.00 cash;

. $80.25 in market value (as described below) of NNG common stock, subject
to proration; and

. 0.80 of a share of NNG preferred stock, subject to proration.

The number of shares of NNG common stock to be issued in exchange for each
share of Litton common stock will be determined by dividing $80.25 by the
average of the closing prices for Northrop Grumman common stock on the NYSE
for the five consecutive trading days ending on the second trading day before
expiration of the offer. No fractional shares of NNG common stock or NNG
preferred stock will be issued. Cash will be delivered in lieu of fractional
shares of NNG common stock or NNG preferred stock.

Holders of Litton preferred stock who desire to tender their shares in the
offer will receive $35.00 in cash for each share.

For more information on the NNG common stock exchange ratio, see "The
Offer" beginning on page 22.

Elections and Proration

Elections by Tendering Stockholders

There is no limit on the number of shares of Litton common stock or Litton
preferred stock that may be exchanged for cash in the offer. There is a limit
on the number of shares of NNG common stock and the number of shares of NNG
preferred stock that may be issued in exchange for Litton common stock in the
offer. The maximum number of shares of NNG common stock that will be issued in
the offer is 13,000,000, and the maximum number of shares of NNG preferred
stock that will be issued in the offer is 3,500,000. It is possible that the
maximum common stock consideration could be reduced, as described under
"Reduction in Number of Shares of NNG Common Stock" below. Elections for the
NNG common stock and the NNG preferred stock will be subject to pro rata
reduction if Litton stockholders request more than the maximum common stock
consideration or the maximum preferred stock consideration, as the case may be.

In addition to deciding whether to receive cash, NNG common stock or NNG
preferred stock, or a combination of this consideration, tendering Litton
common stockholders who elect to receive NNG common stock or NNG preferred
stock must choose among three alternatives for the treatment of any Litton
common stock not exchanged by reason of proration for the class of NNG stock
they have elected to receive:

Alternative A. A tendering Litton common stockholder may make an Alternative
A election with respect to Litton common stock which is tendered for either NNG
common stock or NNG preferred stock. If the total number of NNG common stock
elections (including the deemed elections referred to in the next sentence)
exceeds the NNG common stock available, the Alternative A elections will first
be reduced, pro rata, to the extent necessary so that the total number of
shares of NNG common stock required for common stock elections does not exceed
the maximum common stock consideration. If the tendering stockholder elects to
receive NNG preferred stock, any shares subject to the Alternative A election
which are not exchanged for NNG preferred stock by reason of proration will be
deemed subject to an Alternative A common stock election.

The stockholder's agreement among Northrop Grumman, NNG and Unitrin
provides, in substance, that Unitrin and certain of its subsidiaries will
accept NNG common stock in exchange for all of their shares of Litton common
stock which are not exchanged for NNG preferred stock in the offer. However,
Unitrin and its subsidiaries agreed to accept NNG common stock only to the
extent that other Litton stockholders do not elect to receive the available NNG
common stock. Pursuant to the stockholder's agreement, Unitrin will specify
Alternative A for all of the Litton common stock tendered by it. While
Alternative A may be selected by any holder of Litton common stock, it is
expected that Litton stockholders other than Unitrin will likely find it in
their interests to select either:

. Alternative B, if they wish to maximize the NNG common stock received in
the offer; or

. Alternative C, if they wish to receive only NNG preferred stock or cash.

The stockholder's agreement is described below under "Other Agreements--The
Stockholder's Agreement".

Alternative B. A tendering Litton common stockholder may make an Alternative
B election with respect to Litton common stock which is tendered for either NNG
common stock or NNG preferred stock. In the event that proration of elections
to receive of NNG common stock is still required after the elimination of
shares in

accordance with Alternative A elections, holders of shares of Litton common
stock who elect Alternative B will have their elections to receive NNG common
stock reduced pro rata based on the number of shares covered thereby. If the
tendering Litton common stockholder elects to receive NNG preferred stock, any
shares subject to the Alternative B election which are not exchanged for NNG
preferred stock by reason of proration will be deemed subject to an Alternative
B common stock election.

Alternative C. An Alternative C election is only available for those Litton
common stockholders who elect to receive NNG preferred stock in exchange for
tendered Litton shares. Any such shares which are not exchanged for NNG
preferred stock by reason of proration will be exchanged for $80.00 in cash per
share.

If no election among the three alternatives described above is made in
connection with a tender of Litton common stock in exchange for NNG common
stock or NNG preferred stock, the tendering stockholder will be deemed to have
elected Alternative B.

Pro Rata Reduction of Elections for NNG Stock

If holders tendering Litton common stock elect to receive more than the
maximum common stock consideration or the maximum preferred stock
consideration, elections will be subject to pro rata reduction as described
below.

Elections to receive NNG preferred stock will be reduced, pro rata in
accordance with the numbers of shares covered thereby, until all of the shares
subject to the elections remaining can be exchanged for NNG preferred stock.
Shares of Litton common stock which are not so exchanged by reason of proration
will be exchanged for:

. $80.00 per share in cash, if Alternative C is selected by the tendering
stockholder; or

. NNG common stock (subject to further proration, if required) in all
other cases.

Elections to receive NNG common stock will also be subject to pro rata
reduction, in accordance with the numbers of shares covered thereby, until all
the shares subject to the elections remaining can be exchanged for the maximum
common stock consideration. As described above, shares subject to Alternative A
elections will be reduced before any shares subject to Alternative B elections.
Shares of Litton common stock which are not so exchanged for NNG common stock
by reason of proration will be exchanged for $80.00 in cash per share.

NNG Option to Reduce the Maximum Common Stock Consideration

If the average of the closing prices for Northrop Grumman common stock on
the NYSE for any five consecutive trading days ending not later than two
trading days before expiration of the offer is less than $75.00, NNG may
irrevocably elect to substitute cash for all or a portion of the NNG common
stock at the rate of $80.00 per share of Litton common stock. In such event,
NNG promptly will publicly announce the amount of cash to be substituted for
NNG common stock and the amount of the new maximum common stock consideration
and the offer will be extended, if necessary, in accordance with the applicable
rules of the SEC to allow Litton stockholders to consider the information.

The NNG Preferred Stock

The NNG preferred stock will have the following principal terms:

. Conversion Right. Subject to approval by the stockholders (the
"Stockholder Approval") of Northrop Grumman (if prior to the purchase of
Litton shares in the offer) or by the stockholders of NNG (if
thereafter) of the issuance of the shares of NNG common stock into which
the NNG preferred stock is convertible, shares of NNG preferred stock
will be convertible into shares of NNG common stock at a

conversion price equal to 127% of the average of the closing prices for
Northrop Grumman common stock on the NYSE for the five consecutive trading
days ending on the second trading day before expiration of the offer. The
initial conversion price is subject to adjustment under certain
circumstances, as described in "Description of NNG Capital Stock-Series B
Preferred Stock."

. Dividend Rate. Holders of shares of NNG preferred stock will be entitled
to cumulative cash dividends, payable quarterly in April, July, October
and January of each year. If the NNG preferred stock is issued prior to
the 2001 annual meeting of stockholders of Northrop Grumman (currently
scheduled for May 16, 2001), the initial dividend rate per share will be
$7.00 per year. Commencing after the dividend payment date in October
2001, the dividend rate per share will be $7.00 per year if the
Stockholder Approval has been obtained or $9.00 per year if it has not
been obtained. If the NNG preferred stock is issued after the 2001
Northrop Grumman annual meeting, the initial dividend rate per share
will be $7.00 per year if the Stockholder Approval has been obtained and
$9.00 per year if it has not been obtained. If the dividend rate per
share is set at $9.00 per year, it will be reduced from $9.00 to $7.00
per year after the Stockholder Approval is obtained.

. Redemption.

. Mandatory Redemption For Cash After Twenty Years. Each share of NNG
preferred stock will be subject to mandatory redemption for cash,
in an amount equal to the liquidation value of $100.00 per share of
NNG preferred stock plus accrued but unpaid dividends, whether or
not declared, to the mandatory redemption date. The mandatory
redemption date will be 20 years and one day from the date of
issuance. In the event that Stockholder Approval has not occurred
by the mandatory redemption date, the amount payable for each share
of NNG preferred stock will be the greater of (a) the liquidation
value of $100.00 per share of NNG preferred stock plus accrued but
unpaid dividends to the redemption date, whether or not declared,
and (b) the current market price on the redemption date of the
number of shares of NNG common stock which would be issued upon
conversion of a share of NNG preferred stock into NNG common stock
on the redemption date pursuant to the provision for conversion.

. Optional Redemption For Common Stock After Seven Years. NNG has the
option to redeem all but not less than all of the shares of NNG
preferred stock at any time after seven years from the initial
issuance date for a number of shares of NNG common stock equal to
the liquidation value of $100.00 per share plus accrued but unpaid
dividends, whether or not declared, to the redemption date, divided
by the current market price of a share of NNG common stock on the
redemption date. In the event that Stockholder Approval has not
occurred by the redemption date, the number to be divided in the
above calculation will be the greater of the amount described above
and the current market price on the redemption date of the number of
shares of NNG common stock which would be issued upon conversion of
a share of NNG preferred stock into NNG common stock on the
redemption date pursuant to the provision for conversion.

. Liquidation. In any liquidation of NNG, each share of NNG preferred
stock will be entitled to a liquidation preference of $100.00 plus
accrued but unpaid dividends, whether or not declared, before any
distribution may be made on the NNG common stock or any other class or
series of NNG stock which is junior to the NNG preferred stock. In any
liquidation of NNG, no distribution may be made on any NNG stock ranking
on a parity with the NNG preferred stock, unless the holders of NNG
preferred stock participate ratably in the distribution along with the
holders of any NNG stock that ranks on a parity with the NNG preferred
stock. In the event the Stockholder Approval has not occurred at the
time of liquidation, the amount payable on liquidation will be the
greater of the amount described above and the amount that would be
distributed if such share of NNG preferred stock had been converted into
NNG common stock pursuant to the provision for conversion.

. Change of Control. For a period of not less than 20 business days
following any merger, consolidation, sale of all or substantially all of
NNG's assets, liquidation or recapitalization of the NNG common stock in
which more than one-third of the previously outstanding NNG common stock
is changed into or exchanged for cash, property or securities other than
capital stock of NNG or another corporation, holders of shares of NNG
preferred stock may exchange any and all such shares for shares of NNG
common stock. Each share of NNG preferred stock so exchanged shall be
exchanged for that number of shares of NNG common stock determined by
dividing the liquidation value of $100.00 per share plus accrued and
unpaid dividends as of the exchange date by the current market price of
a share of NNG common stock. In the event the Stockholder Approval has
not occurred by the exchange date, the number to be divided in the above
calculation will be the greater of the amount described above and the
current market price on the exchange date of the number of shares of NNG
common stock which would be issued if such shares of NNG preferred stock
were converted into NNG common stock on the exchange date pursuant to
the provision for conversion.

. Voting Rights. Holders of shares of NNG preferred stock generally will
have no voting rights, except that approval of the holders of two-thirds
of the NNG preferred stock will be required for certain actions that
would adversely affect the rights of such holders. If NNG fails to pay
or declare and set aside funds for six or more quarterly dividends
(whether or not consecutive), the holders of shares of NNG preferred
stock will have the right to elect two directors of NNG.

See "Description of NNG Capital Stock-Series B Preferred Stock--Voting
Rights" on page 73 for a more detailed description of the voting and other
rights and preferences of the NNG preferred stock.

Conditions to the Offer

The offer is subject to conditions, including, but not limited to:

. the satisfaction of the minimum tender condition;

. the expiration or termination of any applicable waiting periods under
the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended
(referred to in this offer to purchase or exchange as the "HSR Act") or
under Council Regulation (EEC) No. 4064/89 of the Council of the
European Union;

. the Registration Statement on Form S-4 filed with the Securities and
Exchange Commission to register the issuance of the NNG common stock and
NNG preferred stock (of which this offer to purchase or exchange is a
part) in the offer will have become effective and not be the subject of
any stop order or proceeding seeking a stop order; and

. the shares of NNG common stock to be issued in the offer will have been
approved for listing on the NYSE.

These conditions and the other conditions to the offer are discussed in
greater detail in "The Offer--Conditions of the Offer" beginning on page 31.

Litton's Support of the Offer and the Litton Merger

Litton's board of directors has determined that the offer is fair to, and in
the best interests of, holders of Litton common stock, and recommends that
holders of Litton common stock accept the offer and tender their shares of
Litton common stock in the offer. Litton's board of directors makes no
recommendation regarding whether holders of Litton preferred stock should
accept the offer and tender their shares of Litton preferred stock in the
offer. Litton's board of directors has approved and declared advisable the
amended merger agreement and the Litton merger. Information about the
recommendation of Litton's board is more fully set forth in Litton's Amended
Solicitation/Recommendation Statement on Schedule 14D-9, which is being mailed
to Litton stockholders together with this offer to purchase or exchange.

Fairness Opinion

Litton has received an opinion from Merrill Lynch & Co., dated January 23,
2001, substantially to the effect that, as of January 23, 2001, the aggregate
consideration to be received by holders of Litton common stock other than
Northrop Grumman and its affiliates pursuant to the offer and the Litton merger
is fair from a financial point of view to the holders of Litton common stock.
The opinion is attached as an annex to Litton's Schedule 14D-9.

Agreement With Litton's Largest Stockholder

Unitrin and certain of its subsidiaries, who collectively owned
approximately 27.8% of the outstanding shares of Litton common stock as of
January 23, 2001, have agreed to tender all of their shares of Litton common
stock in the offer and elect to receive not less than 3,750,000 shares of NNG
preferred stock and, as to the remainder, NNG common stock pursuant to the
stockholder's agreement described in greater detail in "Other Agreements--The
Stockholder's Agreement" on page 61.

Litton Stockholder Approval of the Litton Merger

The Litton merger will require the affirmative vote of at least a majority
of the shares of Litton common stock and Litton preferred stock outstanding on
the record date for the meeting to approve the Litton merger, unless 90% or
more of the outstanding shares of Litton common stock and 90% or more of the
outstanding shares of Litton preferred stock are acquired in the offer, in
which case the Litton merger can be accomplished without a meeting or vote of
the Litton stockholders. If the minimum tender condition is satisfied and NNG
purchases the tendered Litton common stock and Litton preferred stock, approval
of the merger by Litton stockholders will be assured because NNG will own over
50% of the outstanding voting stock of Litton.

Appraisal Rights

There are no appraisal rights available in connection with the offer. After
the offer and subject to Delaware state law, appraisal rights will be available
to holders of Litton common stock, and may be available (depending on
circumstances at the time) to holders of Litton preferred stock who do not vote
in favor of the Litton merger. See "Summary of Certain Statutory Provisions--
Appraisal Rights" beginning on page 82.

Tendering Litton Shares

To tender Litton shares, Litton stockholders should do the following:

. If the Litton shares are held in the stockholder's own name, the
stockholder should complete and sign the enclosed letter of transmittal
and return it with the Litton share certificates to EquiServe Trust
Company, the depositary for the offer, at the applicable address on the
back cover of this offer to purchase or exchange.

. If the Litton shares are held in uncertificated form in the
stockholder's name, the stockholder should complete and sign the
enclosed letter of transmittal and return it to EquiServe Trust Company
at the applicable address printed on the back cover of this offer to
purchase or exchange.

. If the Litton shares are held in "street name" through a broker, the
stockholder will need to ask its broker to tender its Litton shares.

For more information on the timing of the offer, extensions of the offer
period and Litton stockholders' rights to withdraw previously tendered Litton
shares from the offer, see "The Offer" beginning on page 22, or call the
information agent, Georgeson Shareholder Communications Inc., toll-free at
(800) 223-2064.

Litton Stockholders Who Already Tendered Their Shares

Litton stockholders who have already tendered shares of Litton common stock
in the original offer need take no action if they still wish to receive $80.00
in cash per share. If any such holder wishes to elect to receive consideration
other than cash, such holder must submit a new letter of transmittal (or
agent's message, if applicable), properly completed to indicate such election,
and clearly identifying the shares previously tendered.

Litton stockholders who have already tendered shares of Litton preferred
stock need take no action if they still wish to tender such shares for $35.00
in cash per share.

Shares previously tendered will not be returned unless withdrawn as
described herein or upon expiration of the offer if not accepted for payment
or exchange. For information concerning the status of previously tendered
Litton shares, please call the information agent, Georgeson Shareholder
Communications, Inc., toll free at (800) 223-2064.

Tax Consequences of the Receipt of Cash, NNG Common Stock and NNG Preferred
Stock

If the offer and the Litton merger are consummated as contemplated, for
federal income tax purposes:

. Litton stockholders who receive only cash for their Litton common stock
or Litton preferred stock will recognize any gain or loss;

. Litton stockholders who receive solely NNG common stock or NNG preferred
stock for their Litton common stock will recognize neither gain nor
loss; and

. Litton stockholders who receive a combination of cash, NNG common stock
and NNG preferred stock for their Litton common stock will not recognize
any loss and will recognize any gain in an amount not to exceed the cash
received.

The federal income tax consequences of the offer and the Litton merger will
also depend on each Litton stockholder's particular circumstances. For a more
detailed discussion of the potential federal income tax consequences, see
"Material Federal Income Tax Consequences" beginning on page 41. Litton
stockholders also should consult their tax advisors and other financial
advisors for a full understanding of these and other tax consequences.

Extension of the Offer Period

The offer is currently scheduled to expire at Midnight, New York City time,
on Thursday, March 1, 2001.

The amended merger agreement provides that NNG may, without Litton's
consent:

. from time to time extend the offer for successive periods of up to five
business days until each of the conditions to the offer have been
satisfied or waived; or

. extend the offer for any period required by any rule, regulation,
interpretation or position of the SEC.

If the offer is extended for any reason, NNG will promptly publicly
announce the extension no later than 9:00 a.m., New York City time, on the
next business day after the previously scheduled expiration date. During any
extension of the offer, all Litton common stock and Litton preferred stock
previously tendered and not withdrawn will remain subject to the offer,
subject to the holder's right to withdraw. See "The Offer--Withdrawal Rights"
beginning on page 27 and "The Amended Merger Agreement" beginning on page 45
for more details.

Delay; Termination; Waiver; Amendment

Subject to the SEC's rules and regulations and the terms of the amended
merger agreement, NNG also reserves the right, in its sole discretion, at any
time or from time to time:

. to delay acceptance for payment or exchange of any shares of Litton
common stock or Litton preferred stock pursuant to the offer if any of
the conditions of the offer have not been satisfied; and

. to waive any condition (other than the minimum tender condition)

by giving oral or written notice of the delay, termination or amendment to the
depositary and by making a public announcement as promptly as practicable after
the delay, termination or amendment. Subject to applicable law (including Rules
14d-4(d) and 14d-6(c) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), which require that any material change in the information
published, sent or given to stockholders in connection with the offer be
promptly sent to stockholders in a manner reasonably designed to inform
stockholders of such change) and without limiting the manner in which NNG may
choose to make any public announcement, NNG assumes no obligation to publish,
advertise or otherwise communicate any such public announcement other than by
making a release to the Dow Jones News Service.

Withdrawal Rights

Tenders of shares of Litton common stock and Litton preferred stock in the
offer may be withdrawn at any time prior to the expiration of the offer and at
any time after Tuesday, March 6, 2001, unless NNG previously has accepted the
shares for payment.

Reasons for the Proposed Transactions

NNG and Northrop Grumman are proposing the offer and the Litton merger
because they believe that the offer and the Litton merger will significantly
benefit Northrop Grumman's stockholders and customers. Northrop Grumman
believes that the offer and the Litton merger will provide access to new
product areas, increase diversification into new markets, increase market
presence and opportunities and increase operating efficiencies. See "Background
of the Amended Merger Agreement--Reasons for the Offer and the Litton Merger"
beginning on page 40.

Accounting Treatment

NNG will account for the Litton merger as a "purchase" transaction for
accounting and financial reporting purposes, in accordance with United States
generally accepted accounting principles. Accordingly, NNG will make a
determination of the fair value of Litton's assets and liabilities and allocate
the purchase price on its books to the acquired assets.

Material Differences in Rights of Stockholders

The governing documents of NNG and Litton vary, and to that extent, holders
of Litton common stock will have different rights as NNG stockholders. The
differences are described in more detail under "Comparison of Stockholders'
Rights" beginning on page 77.

Questions About the Offer and the Litton Merger

(800) 223-2064.

IMPORTANT CONSIDERATIONS CONCERNING ELECTIONS TO RECEIVE NNG STOCK

In deciding whether to tender shares of Litton stock pursuant to the offer,
Litton stockholders should read this offer to purchase or exchange and the
accompanying Schedule 14D-9 of Litton carefully. Litton common stockholders
also should carefully consider the following factors before electing to
receive NNG stock in the offer.

Elections to Receive NNG Stock are Subject to Pro Rata Reduction Because of
the Limited Numbers of Shares Available

Only 13,000,000 shares of NNG common stock and 3,500,000 shares of NNG
preferred stock are available for exchange in the offer. The maximum common
stock consideration could be reduced as described below under "--The Amount of
NNG Common Stock Offered in Exchange for Litton Common Stock is Subject to
Possible Reduction." If Litton common stockholders elect to receive more than
the available number of shares of either class of NNG stock, their elections
will be subject to pro rata reduction. Several alternative elections are
available to Litton common stockholders for treatment of any shares of Litton
common stock not exchanged by reason of proration for the class of NNG stock
they have elected to receive. Litton common stockholders who are considering
such elections should carefully consider the information provided herein under
"The Offer--Possible Pro Rata Reductions of Elections for NNG Stock."

The Trading Market for NNG Preferred Stock May Be Limited

The total number of NNG preferred shares to be issued in the offer is
limited to 3,500,000, with each share having a liquidation preference of
$100.00. As the result, the total initial liquidation value of the issue will
be no more than $350,000,000, and the liquidity of those shares may be
limited. Of course, the actual market value of the NNG preferred stock may be
more or less than $100.00 per share depending on circumstances over time.

Resales of NNG Common Stock Following the Offer May Adversely Affect the
Market Value of Such Shares

The issuance of 13,000,000 new shares of NNG common stock in the offer
could lead to a significant redistribution of the new shares following their
initial issuance. Resales of a large number of the new NNG shares could
adversely affect the market price for NNG common stock.

The Exchange Ratio for NNG Common Stock in the Offer, and the Conversion
Price for the NNG Preferred Stock, Will Not be Known Until Two Trading Days
Prior to Expiration of the Offer

The exact number of NNG common shares to be exchanged for each Litton
common share will be determined by dividing $80.25 by the average of the
closing prices for Northrop Grumman common stock on the NYSE for the five
consecutive trading days ending on the second trading day before expiration of
the offer. Accordingly, Litton stockholders will not be able to know the NNG
common stock exchange ratio until the last two trading days during which the
offer is open. Further, the exchange ratio which results may not reflect the
actual market price for NNG common stock following completion of the offer.

The conversion price for NNG preferred stock will be 127% of the average of
the closing prices of the Northrop Grumman common stock used to set the NNG
common stock exchange ratio. Accordingly, the conversion price for NNG
preferred stock will also not be known until two trading days prior to the
expiration of the offer.

The Amount of NNG Common Stock Offered in Exchange for Litton Common Stock
is Subject to Possible Reduction

$75.00, NNG will have the irrevocable option to reduce the number of shares of
NNG common stock available for exchange in the offer and substitute cash at
the rate of $80.00 per share of Litton common stock. If this should occur, a
public announcement of the fact will be made and the offer will be extended,
if necessary, in accordance with the applicable rules of the SEC to allow
Litton stockholders to consider the information.

Convertibility of the NNG Preferred Stock is Subject to a Vote of Northrop
Grumman Stockholders Which Will Not Occur Until the 2001 Meeting of
Northrop Grumman Stockholders

The issuance of NNG common stock upon conversion of the NNG preferred stock
is conditioned upon the approval of stockholders of Northrop Grumman (if such
vote occurs prior to the issuance of shares in the offer) or NNG (if the vote
occurs thereafter). The matter will be voted on at the 2001 annual meeting of
stockholders, currently scheduled for May 16, 2001, which is expected to be
after expiration of the offer. As the result, Litton stockholders who elect to
receive NNG preferred stock must recognize that such shares may not be
convertible into common stock. See "Description of NNG Capital Stock--Series B
Preferred Stock."

The Indebtedness of NNG Following the Offer Will be Much Higher Than the
Existing Indebtedness of Northrop Grumman

The indebtedness of Northrop Grumman as of September 30, 2000 was
approximately $1.820 billion. NNG's pro forma indebtedness as of September 30,
2000 giving effect to the offer and the Litton merger and assuming the Minimum
Equity Issuance (as described in "Selected Consolidated Financial Data"
below), is approximately $6.4 billion. As a result of the increase in debt,
demands on the cash resources of Northrop Grumman will increase after the
Litton merger, which could have important effects on the investment in NNG's
common stock and NNG's preferred stock. For example, the increased levels of
indebtedness could:

. reduce funds available for investment in research and development and
capital expenditures; or

. create competitive disadvantages compared to other companies with lower
debt levels.

Successful Integration of the Northrop Grumman and Litton Businesses is not
Assured

Integrating and coordinating the operations and personnel of Northrop
Grumman and Litton will involve complex technological, operational and
personnel-related challenges. This process will be time-consuming and
expensive, and may disrupt the business of the companies. The integration of
the companies may not result in the benefits expected by the companies. The
difficulties, costs and delays that could be encountered may include:

. unanticipated issues in integrating the information, communications and
other systems;

. negative impacts on employee morale and performance as a result of job
changes and reassignments;

. loss of customers;

. unanticipated incompatibility of systems, procedures and operating
methods;

. inability to obtain necessary consents of third parties;

. unanticipated costs in termination or relocation of facilities and
operations, and

. the effect of complying with any government imposed organizational
conflict-of-interest rules.

Risks Relating to the Businesses of Northrop Grumman and Litton

Results of operation of NNG will be subject to numerous risks affecting the
businesses of Northrop Grumman and Litton, many of which are beyond the
companies' control. Many of these risks are identified under "Forward-Looking
Statements" on page 87.

SELECTED CONSOLIDATED FINANCIAL DATA

The following is a summary of selected historical consolidated financial
data of Northrop Grumman for each of the years in the five-year period ended
December 31, 1999 and for the nine-month periods ended September 30, 2000 and
1999 and selected unaudited pro forma combined financial data of Northrop
Grumman and Litton for the year ended December 31, 1999 and the nine-month
period ended September 30, 2000. The operating results for the nine months
ended September 30, 2000 are not necessarily indicative of results for the full
fiscal year ending December 31, 2000. See "Additional Information" on page 86.
Litton stockholders should read this summary together with the financial
statements referred to below and incorporated by reference and their
accompanying notes and in conjunction with management's discussion and analysis
of operations and financial conditions of Northrop Grumman and Litton contained
in such reports.

The historical consolidated financial data of Northrop Grumman for each of
the years in the three year period ended December 31, 1999 are derived from the
audited financial statements of Northrop Grumman contained in its Current
Report on Form 8-K as filed on August 8, 2000, which is incorporated by
reference in this offer to purchase or exchange. The historical consolidated
financial data for the fiscal years ended December 31, 1996 and 1995 are
derived from the audited financial statements of Northrop Grumman. The
historical consolidated financial data for the nine-month periods ended
September 30, 2000 and 1999 are derived from the unaudited financial statements
of Northrop Grumman contained in its Quarterly Report on Form 10-Q as filed on
November 3, 2000, which is incorporated by reference in this offer to purchase
or exchange.

The selected unaudited pro forma combined financial data of Northrop Grumman
and Litton was derived from Northrop Grumman's audited consolidated financial
statements for the year ended December 31, 1999, Northrop Grumman's unaudited
consolidated financial statements for the nine months ended and as of September
30, 2000, Litton's audited consolidated financial statements for the year ended
July 31, 2000 and Litton's unaudited consolidated financial statements for the
quarter ended and as of October 31, 2000. In addition, the audited financial
statements contained in Litton's Annual Report on Form 10-K for the fiscal year
ended July 31, 1999 and the unaudited financial statements of Litton contained
in Litton's Quarterly Reports on Form 10-Q for the periods ended January 31,
2000 and 1999 have been used to bring the financial reporting periods of Litton
to within 31 days of those of Northrop Grumman.

The selected unaudited pro forma combined financial data give effect to the
offer and the Litton merger as if they had occurred on the dates referenced
under "Unaudited Pro Forma Condensed Combined Financial Information" beginning
on page 68. The selected unaudited pro forma combined financial data do not
include the realization of any cost savings from operating efficiencies,
synergies or other restructurings resulting from the offer and the Litton
merger. Two pro forma transaction scenarios are presented: Minimum Equity
Issuance and Maximum Equity Issuance. The Minimum Equity Issuance scenario is
based upon the assumption that Unitrin tenders its shares of Litton common
stock for NNG stock as described in "Other Agreements--The Stockholder's
Agreement," beginning on page 61 and all other stockholders tender their shares
for cash. The Maximum Equity Issuance scenario is based upon the assumption
that the maximum number of shares of NNG common stock (i.e. 13,000,000) and
maximum number of shares of NNG preferred stock (i.e. 3,500,000) are issued,
with the remainder of the consideration in the offer paid in cash. The selected
unaudited pro forma combined financial data do not purport to represent what
NNG's results of operations or financial position actually would have been if
the transactions referred to therein had been consummated on the date or for
the periods indicated or what such results will be for any future date or any
future period. Litton stockholders should read this summary together with
"Unaudited Pro Forma Condensed Combined Financial Information" beginning on
page 67 and the accompanying notes.

COMPARATIVE PER SHARE INFORMATION

The following table summarizes unaudited per share information for Northrop
Grumman and Litton on a historical, pro forma combined and equivalent pro forma
combined basis. The following information should be read in conjunction with
the audited consolidated financial statements of Northrop Grumman and Litton,
the unaudited interim consolidated financial statements of Northrop Grumman and
Litton, and the unaudited pro forma condensed combined financial information
included elsewhere or incorporated by reference in this offer to purchase or
exchange. The pro forma information is presented for illustrative purposes only
and is not necessarily indicative of the operating results or financial
position that would have occurred if the offer, the Litton merger and the
Northrop reorganization had been consummated as of the beginning of the
respective periods presented, nor is it necessarily indicative of the future
operating results or financial position of the combined companies. The
historical book value per share is computed by dividing total stockholders'
equity by the number of common shares outstanding at the end of the period. The
pro forma per share earnings from continuing operations is computed by dividing
the pro forma income from continuing operations by the pro forma weighted
average number of shares outstanding. The pro forma combined book value per
share is computed by dividing total pro forma stockholders' equity by the pro
forma number of common shares outstanding at the end of the period. Litton's
equivalent pro forma combined per share amounts are calculated by multiplying
Northrop Grumman's pro forma combined per share amounts by 0.9106, the
percentage of a share of NNG common stock that would be exchanged for each
share of Litton common stock in the offer, based upon the average of the
closing prices for Northrop Grumman common stock on the NYSE for the five
consecutive trading days ending on January 26, 2001 ($88.125).

THE OFFER

Exchange of Litton Shares; Exchange Ratio

Litton stockholders who tender shares of Litton common stock in the offer
may elect to receive any of the following in exchange for each share of Litton
common stock:

. $80.00 in cash;

. $80.25 in market value of shares of NNG common stock, determined by
dividing $80.25 by the average of the closing prices for Northrop Grumman
common stock on the NYSE for the five consecutive trading days ending on
the second trading day before expiration of the offer; or

. 0.80 of a share of NNG preferred stock.

Litton stockholders who tender shares of Litton preferred stock in the offer
will receive $35.00 in cash in exchange for each share of Litton preferred
stock. Holders of Litton preferred stock cannot exchange their Litton preferred
stock for NNG common stock or NNG preferred stock, only cash.

Each form of consideration paid in the offer will be paid net of any
required withholding of taxes and without the payment of interest.

Elections by Tendering Stockholders

There is no limit on the number of shares of Litton common stock or Litton
preferred stock that may be exchanged for cash in the offer. There is a limit
on the number of shares of NNG common stock and the number of shares of NNG
preferred stock that may be issued in exchange for Litton common stock in the
offer. The maximum number of shares of NNG common stock that will be issued in
the offer is 13,000,000, and the maximum number of shares of NNG preferred
stock that will be issued in the offer is 3,500,000. It is possible that the
maximum common stock consideration could be reduced. Elections for the NNG
common stock and the NNG preferred stock will be subject to pro rata reduction
if Litton common stockholders request more than the maximum common stock
consideration or the maximum preferred stock consideration, as the case may be.

In addition to deciding whether to receive cash, NNG common stock or NNG
preferred stock, or a combination of this consideration, tendering stockholders
who elect to receive NNG common stock or NNG preferred stock must choose among
the available alternatives described below for the treatment of any shares of
Litton common stock not exchanged, by reason of proration, for the form of NNG
stock they have elected to receive:

Alternative A. A tendering Litton stockholder may make an Alternative A
election with respect to Litton common stock which is tendered for either NNG
common stock or NNG preferred stock. If the total number of NNG common stock
elections (including the deemed elections referred to in the next sentence)
exceeds the NNG common stock available, the Alternative A elections will first
be reduced, pro rata, to the extent necessary so that the total number of
shares of NNG common stock required for common stock elections does not exceed
the maximum common stock consideration. If the tendering stockholder elects to
receive NNG preferred stock, any shares subject to the Alternative A election
which are not exchanged for NNG preferred stock by reason of proration will be
deemed subject to an Alternative A common stock election.

The stockholder's agreement provides, in substance, that Unitrin and certain
of its subsidiaries will accept NNG common stock in exchange for all of their
shares of Litton common stock which are not exchanged for NNG preferred stock
in the offer. However, Unitrin and its subsidiaries agreed to accept NNG common
stock only to the extent that other Litton stockholders do not elect to receive
the available NNG common stock. Pursuant to the stockholder's agreement,
Unitrin will specify Alternative A for all of the Litton common stock

tendered by it. While Alternative A may be selected by any holder of Litton
common stock, it is expected that Litton stockholders other than Unitrin will
likely find it in their interests to select either:

. Alternative B, if they wish to maximize the NNG common stock received in
the offer (for any shares not exchanged, by reason of proration, for NNG
preferred stock, or otherwise); or

. Alternative C, if they wish to receive only NNG preferred stock or cash.

The stockholder's agreement is described below under "Other Agreements--The
Stockholder's Agreement."

Alternative B. A tendering Litton stockholder may make an Alternative B
election with respect to Litton common stock which is tendered for either NNG
common stock or NNG preferred stock. In the event that proration of elections
to receive shares of NNG common stock is still required after the elimination
of shares in accordance with Alternative A elections, holders of shares of
Litton common stock who elect Alternative B will have their elections to
receive NNG common stock reduced pro rata based on the number of shares covered
thereby. If the tendering stockholder elects to receive NNG preferred stock,
any shares subject to the Alternative B election which are not exchanged for
NNG preferred stock by reason of proration will be deemed subject to an
Alternative B common stock election.

If no election among the three alternatives described above is made in
connection with a tender of Litton common stock in exchange for NNG common or
preferred stock, the tendering stockholder will be deemed to have elected
Alternative B.

Pro Rata Reduction of Elections for NNG Stock

. $80.00 per share in cash, if Alternative C is selected by the tendering
stockholder; or

. NNG common stock (subject to further proration, if required) in all other
cases.

Reduction in Number of Shares of NNG Common Stock

Pursuant to the amended merger agreement, if the average of the closing
prices for Northrop Grumman common stock on the NYSE is less than $75.00 for
any five consecutive trading days ending not later than two trading days before
expiration of the offer, NNG will have the option to irrevocably elect to
reduce the number of shares of NNG common stock available for exchange in the
offer and substitute cash at the rate of $80.00

per share of Litton common stock. If this should occur, NNG will promptly
publicly announce the amount of cash to be substituted and the new maximum
common stock consideration and will extend the offer, if necessary, in
accordance with the applicable rules of the SEC to allow Litton stockholders to
consider the information.

Illustrative Table of NNG Common Stock Exchange Ratios at Specified Average
Closing Prices

The following table illustrates the number of shares of NNG common stock
that would be issued for one share of Litton common stock at each of the
average Northrop Grumman trading prices presented in the table.

The values of Northrop Grumman common stock used in the table above are for
purposes of illustration only. The average closing prices used in calculating
the NNG common stock exchange ratio may be higher or lower than these numbers,
depending on what the average of the closing prices of Northrop Grumman common
stock on the NYSE actually is for the five consecutive trading days ending two
trading days before expiration of the offer.

More Information about NNG Common Stock Exchange Ratio

NNG will notify Litton stockholders by issuing a press release announcing
the final NNG common stock exchange ratio and filing the press release with the
SEC. Litton stockholders may also call the information agent, Georgeson
Shareholder Communications Inc., at any time toll free at (800) 223-2064 to
request information about the NNG common stock exchange ratio, including the
average trading price of shares of Northrop Grumman common stock used to
calculate the number of shares of NNG common stock issuable per share of Litton
common stock in the offer.

Stockholder Rights Plans

The offer to acquire Litton common stock is also an offer to acquire the
associated preferred stock purchase rights issued pursuant to the rights
agreement dated as of August 17, 1994 between Litton and The Bank of New York
as amended as of December 21, 2000 and January 23, 2001. All references to
Litton common stock include the associated rights to purchase preferred stock.
Under no circumstances will additional consideration be paid for those rights.

The shares of NNG common stock to be issued in the offer include the
associated NNG preferred stock purchase rights pursuant to the rights agreement
between NNG and ChaseMellon Shareholder Services to be entered into prior
expiration of the offer. The NNG rights agreement will be on the same terms and
conditions as Northrop Grumman's current rights agreement dated as of September
23, 1998 between Northrop Grumman and ChaseMellon Shareholder Services.
However, provisions will be added to permit the acquisition by Unitrin of NNG
common stock (and NNG common stock issuable upon conversion of the NNG
preferred stock) as contemplated by the offer and the stockholder's agreement
described under "Other Agreements--The Stockholder's Agreement" on page 61. All
references to shares of NNG common stock in this offer to purchase or exchange
are also references to the associated NNG preferred stock purchase rights.

Stockholders List

NNG has relied on Litton's stockholders list and security position listings
to communicate with Litton stockholders and to distribute the offer. NNG will
send this offer to purchase or exchange, related letter of transmittal and
other relevant materials to Litton stockholders and to brokers, dealers,
commercial banks, trust companies and similar persons whose names, or the
names of whose nominees, appear on Litton's stockholders list or, if
applicable, who are listed as participants in a clearing agency's security
position listing.

Extension; Termination; Amendment

The offer is currently scheduled to expire at Midnight, New York City time,
on Thursday, March 1, 2001.

rSubject to the terms of the amended merger agreement, NNG may extend the
period of time during which the offer remains open without Litton's consent by
giving oral or written notice of such extension to the depositary. If the
offer is extended for any reason, NNG will make an announcement to that effect
no later than 9:00 a.m., New York City time, on the next business day after
the previously scheduled expiration date. The amended merger agreement,
subject to certain exceptions, allows NNG to extend the offer for successive
periods of up to five business days until all conditions have been satisfied
or waived. Northrop Grumman has agreed to cause NNG to extend the offer for
the shortest time periods which it reasonably believes are necessary until the
consummation of the offer if the conditions of the offer have not been
satisfied or waived. During any such extension, all shares of Litton stock
previously tendered and not withdrawn will remain subject to the offer,
subject to each tendering stockholder's right to withdraw its Litton common
stock or Litton preferred stock. Litton stockholders should read the
discussion under the caption "The Offer--Withdrawal Rights" beginning on page
27 for more details about withdrawal rights.

Subject to the SEC's applicable rules and regulations and subject to the
terms of the amended merger agreement, NNG also reserves the right, in its
sole discretion, at any time or from time to time, (a) to delay acceptance for
purchase or exchange of or, regardless of whether NNG previously accepted
Litton stock, the purchase or exchange of any Litton stock pursuant to the
offer and (b) to waive any condition (other than the minimum tender condition)
or otherwise amend the offer by giving oral or written notice of such delay or
amendment to the depositary and by making a public announcement. NNG will
follow any amendment or delay as promptly as practicable with a public
announcement. Subject to applicable law (including Rules 14d-4(d) and 14d-6(c)
under the Exchange Act, which require that any material change in the
information published, sent or given to stockholders in connection with the
offer be promptly sent to stockholders in a manner reasonably designed to
inform stockholders of such change) and without limiting the manner in which
NNG may choose to make any public announcement, NNG assumes no obligation to
publish, advertise or otherwise communicate any such public announcement other
than by making a release to the Dow Jones News Service.

Subject to the terms of the amended merger agreement, if NNG makes a
material change in the terms of the offer or the information concerning the
offer (including any election to substitute cash for NNG common stock), or if
NNG waives a material condition of the offer, NNG will extend the offer to the
extent required under the Exchange Act. If, prior to the expiration date, NNG
changes the consideration offered for Litton shares, that change will apply to
all holders whose Litton common stock or Litton preferred stock are accepted
for purchase or exchange pursuant to the offer. If at the time notice of that
change is first published, sent or given to Litton stockholders, the offer is
scheduled to expire at any time earlier than the tenth business day from and
including the date that such notice is first published, sent or given, NNG
will extend the offer in accordance with the applicable rules of the SEC to
allow Litton stockholders to consider the information. For purposes of the
offer, a "business day" means any day other than a Saturday, Sunday or federal
holiday and consists of the time period from 12:01 a.m. through 12:00
Midnight, New York City time.

Purchase and Exchange of Litton Stock; Delivery of NNG Stock

Upon the terms and subject to the conditions of the offer, including the
terms and conditions of any extension or amendment of the offer, NNG will
accept, and will purchase or exchange, shares of Litton common stock (in
accordance with the elections of tendering Litton stockholders) or Litton
preferred stock validly tendered and not properly withdrawn as promptly as
practicable after the expiration date. In addition, subject to applicable rules
of the SEC and the terms of the amended merger agreement, NNG expressly
reserves the right to delay acceptance of Litton stock in order to comply with
any applicable law. In all cases, purchases and exchanges of Litton stock
tendered and accepted for exchange will be made only after timely receipt by
the depositary of:

. certificates for the shares of Litton common stock or Litton preferred
stock tendered (if such certificates were ever issued) or a confirmation
of a book-entry transfer of those shares of Litton common stock or Litton
preferred stock in the depositary's account at The Depository Trust
Company, referred to as the "DTC";

. a properly completed and duly executed letter of transmittal (or a
facsimile of that document) or agent's message if applicable; and

. any other required documents.
For purposes of the offer, NNG will be deemed to have accepted for purchase
and exchange shares of Litton stock tendered when NNG notifies the depositary
of its acceptance of those shares. The depositary will deliver cash, NNG common
stock and NNG preferred stock in exchange for Litton stock pursuant to the
offer. The depositary will act as agent for tendering stockholders for the
purpose of receiving cash and shares of NNG stock (including cash to be paid
instead of fractional shares) from NNG and transmitting such cash and NNG stock
to tendering Litton stockholders. NNG will not pay interest on any amount
payable in the offer or the Litton merger, regardless of any delay in making
payment.

If NNG does not accept any Litton stock tendered in the offer for any
reason, or if stock certificates are submitted for more shares of Litton stock
than are tendered, NNG will return certificates for such tendered or untendered
Litton stock, as the case may be, without expense to the tendering stockholder
or, in the case of Litton stock tendered by book-entry transfer into the
depositary's account at DTC pursuant to the procedures set forth below under
the discussion entitled "The Offer--Procedures for Tendering," those shares of
Litton stock will be credited to an account maintained within DTC, as soon as
practicable following expiration or termination of the offer.

If NNG increases the consideration offered to Litton stockholders in the
offer prior to the expiration date, such increased consideration will be given
to all stockholders whose Litton shares are tendered pursuant to the offer,
whether or not such Litton shares were tendered or accepted for exchange prior
to such increase in consideration.

Cash Instead of Fractional Shares of NNG Stock

NNG will not issue certificates representing fractional shares of NNG stock
pursuant to the offer. Instead, each tendering stockholder who would otherwise
be entitled to a fractional share of NNG stock will receive cash in an amount
equal to such fraction (expressed as a decimal and rounded to the nearest 0.01
of a share) multiplied by (i) the average of the closing prices for Northrop
Grumman common stock on the NYSE for the five consecutive trading days ending
on the second trading day before expiration of the offer, in the case of NNG
common stock, or (ii) $100.00 in the case of NNG preferred stock, in each case
minus any required withholding of taxes and without payment of interest.

Transfer Charges

Litton stockholders who tender Litton common stock or Litton preferred stock
in the offer, will not be obligated to pay any charges or expenses of the
depositary. Except as set forth in the instructions to the letter of
transmittal, transfer taxes on tenders will be paid by NNG or on NNG's behalf.
Record owners of Litton common stock or Litton preferred stock who tender
shares in the offer will not have to pay brokerage fees or incur similar
expenses. Holders who own Litton common stock or Litton preferred stock through
a broker or other nominee, and whose broker or other nominee exchanges such
Litton stock on the holder's behalf, may be subject to a charge from the broker
or nominee for doing so. Litton stockholders should consult their broker or
nominee to determine whether any charges will apply.

Interest

NNG will not pay interest on any amount payable in the offer or the Litton
merger, regardless of any delay in making payment.

Withdrawal Rights

All tenders of Litton stock in the offer are irrevocable, except that Litton
stock previously tendered may be withdrawn at any time prior to expiration of
the offer, and, unless previously accepted for purchase or exchange pursuant to
the offer, may also be withdrawn at any time after Tuesday, March 6, 2001.

For a withdrawal to be effective, the depositary must receive a written,
telegraphic, telex or facsimile transmission notice of withdrawal at one of its
addresses set forth on the back cover of this offer to purchase or exchange,
and such notice must include the tendering stockholder's name, the number of
shares of Litton common stock or Litton preferred stock to be withdrawn and the
name of the registered holder, if it is different from that of the person who
tendered the shares of Litton stock being withdrawn.

A financial institution must guarantee all signatures on the notice of
withdrawal. Most banks, savings and loan associations and brokerage houses are
able to effect these signature guarantees. The financial institution must be a
participant in the Securities Transfer Agents Medallion Program, the NYSE
Medallion Signature Program or the Stock Exchange Medallion Program, any of
which is an "eligible institution," unless the Litton shares have been tendered
for the account of any eligible institution. If Litton shares have been
tendered pursuant to the procedures for book-entry transfer discussed under the
caption entitled "Procedures for Tendering," any notice of withdrawal must
specify the name and number of the account at DTC to be credited with the
withdrawn Litton shares and must otherwise comply with DTC's procedures. If
certificates have been delivered or otherwise identified to the depositary, the
name of the registered holder and the serial numbers of the particular
certificates evidencing the shares of Litton stock being withdrawn must also be
furnished to the depositary, prior to the physical release of such
certificates. NNG will decide all questions as to the form and validity
(including time of receipt) of any notice of withdrawal, in NNG's sole
discretion, and NNG's decision will be final and binding. Neither NNG, the
depositary, the information agent nor any other person has any duty to give
notification of any defects or irregularities in any notice of withdrawal or
will incur any liability for failure to give any such notification. Any shares
of Litton stock properly withdrawn will be deemed not to have been validly
tendered for purposes of the offer. However, a Litton stockholder may retender
withdrawn shares of Litton stock by following one of the procedures discussed
in the section entitled "The Offer--Procedures for Tendering" below at any time
prior to expiration of the offer.

If a holder withdraws any shares of Litton common stock, such holder
automatically withdraws the associated rights to purchase preferred stock. A
holder may not withdraw the rights to purchase preferred stock unless the
associated shares of Litton common stock are also withdrawn.

Procedures for Tendering

To validly tender Litton shares pursuant to the offer, before expiration of
the offer, a Litton stockholder must transmit a properly completed and duly
executed letter of transmittal (or manually executed facsimile of that
document), along with any required signature guarantees, an agent's message in
connection with a book-entry transfer, and any other required documents to the
depositary at one of its addresses set forth on the back cover of this offer to
purchase or exchange, and certificates for Litton stock being tendered must be
received by the depositary at such address. Shares of Litton stock held in
book-entry form must be tendered pursuant to the procedures for book-entry
exchange set forth below and a confirmation of receipt of such tender (we refer
to this confirmation below as a "book-entry confirmation") must be received by
the depository. In the alternative, Litton stockholders may comply with the
guaranteed delivery procedures set forth below.

The term "agent's message" means a message, transmitted by DTC to the
depositary and forming a part of a book-entry confirmation, which states that
DTC has received an express acknowledgment from the participant exchanging the
Litton shares which are the subject of such book-entry confirmation, that the
participant has received and agrees to be bound by the terms of the letter of
transmittal and that NNG may enforce that agreement against such participant.

The depositary will establish accounts with respect to the Litton stock at
DTC for the offer within two business days after the date of this offer to
purchase or exchange, and any financial institution that is a participant in
DTC may make book-entry delivery of Litton stock by causing DTC to transfer
such stock into the depositary's account in accordance with DTC's procedure for
such transfer. However, although delivery of Litton stock may be effected
through book-entry at DTC, the letter of transmittal (or facsimile thereof),
with any required signature guarantees, or an agent's message in connection
with a book-entry transfer, and any other required documents, must be
transmitted to the depositary at the applicable address set forth on the back
cover of this offer to purchase or exchange prior to the expiration date, or
the guaranteed delivery procedures described below must be followed.

Signatures on all letters of transmittal must be guaranteed by an eligible
institution, except in cases in which Litton stock is tendered either by a
registered holder of Litton stock who has not completed either the box entitled
"Special Payment Instructions" or the box entitled "Special Delivery
Instructions" on the letter of transmittal or for the account of an eligible
institution.

If the certificates for Litton stock are registered in the name of a person
other than the person who signs the letter of transmittal, or if certificates
for untendered Litton shares are to be issued to a person other than the
registered holder(s), the certificates must be endorsed or accompanied by
appropriate stock powers, in either case signed exactly as the name of the
registered owner appears on the certificates, with the signature(s) on the
certificates or stock powers guaranteed in the manner described above.

The method of delivery of Litton share certificates and all other required
documents, including delivery through DTC, is at the tendering stockholder's
option and risk, and delivery will be deemed made only when actually received
by the depositary. If delivery is by mail, NNG recommends registered mail with
return receipt requested, properly insured. In all cases, holders must allow
sufficient time to ensure timely delivery.

To prevent backup federal income tax withholding with respect to any cash
received in the offer, the depositary must be provided with the tendering
stockholder's correct taxpayer identification number and certification whether
the tendering stockholder is subject to backup withholding of federal income
tax by means of the substitute Form W-9 included in the letter of transmittal.
Some stockholders (including, among others, all corporations and some foreign
individuals) are not subject to backup withholding and reporting requirements.
In order for a foreign individual to qualify as an exempt recipient, the
stockholder must submit a Form W-8, signed under penalties of perjury,
attesting to that person's exempt status.

A stockholder who wishes to tender shares of Litton stock in the offer and
whose stock certificates are not immediately available or who cannot deliver
the certificates and all other required documents to the depositary prior to
the expiration date or cannot complete the procedure for book-entry transfer on
a timely basis, may nevertheless tender Litton common stock and Litton
preferred stock, so long as all of the following conditions are satisfied:

(a) tender is made by or through an eligible institution;

(b) a properly completed and duly executed notice of guaranteed delivery,
substantially in the form made available by NNG, is received by the
depositary as provided below on or prior to the expiration date; and

(c) the certificates for all shares of Litton common stock or Litton
preferred stock to be tendered (or a confirmation of a book-entry
transfer of such securities into the depositary's account at DTC as
described above), in proper form for transfer, together with a properly
completed and duly executed letter of transmittal (or facsimile
thereof), with any required signature guarantees (or, in the case of a
book-entry transfer, an agent's message) and all other documents
required by the letter of transmittal are received by the depositary
within three NYSE trading days after the date the notice of guaranteed
delivery is executed.

The notice of guaranteed delivery may be delivered to the depositary by hand
or transmitted by telegram, telex, facsimile transmission or mail. A guarantee
by an eligible institution in the form set forth in that notice must be
provided.

In all cases, NNG will exchange shares of Litton common stock or Litton
preferred stock tendered and accepted for exchange only after timely receipt by
the depositary of certificates for such shares (or timely confirmation of a
book-entry transfer of such securities into the depositary's account at DTC as
described above), properly completed and duly executed letter(s) of transmittal
(or facsimile(s) thereof), or an agent's message in connection with a book-
entry transfer, and any other required documents. Accordingly, holders may be
paid at different times depending upon when the depositary actually receives
the certificates for their Litton common stock or Litton preferred stock or
confirmations of book-entry transfers of those shares.

If a holder's shares of Litton common stock or Litton preferred stock were
never issued in certificated form, the holder must follow all of the
requirements for tendering shares other than the requirement to deliver the
share certificates for the tendered shares. A holder who has lost a share
certificate, must contact the Bank of New York, the transfer agent for the
Litton stock, at (800) 432-0140 and receive a replacement certificate in order
to tender the Litton shares represented by the lost share certificate.
Receiving a replacement certificate may take time, so Litton stockholders who
have lost their share certificate and want to tender Litton shares in the offer
should contact the transfer agent to request a replacement certificate as soon
as possible.

By executing a letter of transmittal as set forth above, a tendering Litton
stockholder irrevocably appoints NNG's designees as the holder's attorneys-in-
fact and proxies, each with full power of substitution, to the full extent of
the holder's rights with respect to the Litton common stock or Litton preferred
stock tendered in the offer and any other Litton common stock or Litton
preferred stock and other securities issued or issuable in respect of the
Litton common stock or Litton preferred stock on or after February 1, 2001.
That appointment is effective, and voting rights will be affected, when and
only to the extent that NNG deposits with the depositary cash, the shares of
NNG common stock and NNG preferred stock for the Litton common stock tendered.
All such proxies shall be considered coupled with an interest and are not
revocable. Upon the effectiveness of such appointment, all prior proxies of the
tendering stockholder will be revoked, and any subsequent proxies will not be
deemed effective. NNG's designees will be empowered, among other things, to
exercise all of the tendering stockholder's voting and other rights as they, in
their sole discretion, deem proper at any annual, special or adjourned meeting
of Litton's stockholders or otherwise. NNG reserves the right to require that,
in order for shares of Litton common stock and Litton preferred stock to be
deemed validly tendered, NNG must be able to exercise full voting rights to the
extent permitted under applicable law with respect to such shares immediately
upon acceptance of such shares for purchase or exchange.

NNG will determine questions as to the validity, form, eligibility,
including time of receipt, and acceptance for exchange of any tender of Litton
common stock or Litton preferred stock, in its sole discretion, and NNG's
determination shall be final and binding. NNG reserves the absolute right to
reject any tenders of Litton common stock or Litton preferred stock that NNG
determines are not in proper form or the acceptance for exchange of or exchange
for which may, in the opinion of NNG's counsel, be unlawful. NNG also reserves
the absolute right to waive any of the conditions of the offer (other than the
minimum tender condition) or any defect or irregularity in the tender of any
shares of Litton common stock or Litton preferred stock. No tender of Litton
common stock or Litton preferred stock will be deemed to have been validly made
until all defects and irregularities have been cured or waived. Neither NNG,
the depositary, the information agent nor any other person is under any duty to
give notification of any defects or irregularities in the tender of any Litton
common stock or Litton preferred stock or will incur any liability for failing
to give any such notification. NNG's interpretation of the terms and conditions
of the offer, including the letter of transmittal and instructions thereto will
be final and binding.

The tender of shares of Litton stock pursuant to any of the procedures
described above will constitute a binding agreement between NNG and the
tendering stockholder upon the terms and subject to the conditions of the
offer.

Purpose of the Offer; The Litton Merger

NNG is making the offer in order to acquire control of, and ultimately the
entire common equity interest in, Litton. The offer is the first step in NNG's
acquisition of Litton, and is intended to facilitate the acquisition of all
Litton shares. Litton stockholders do not have appraisal rights in connection
with the offer. As soon as practicable after consummation of the offer, NNG
intends to merge LII Acquisition, its wholly-owned subsidiary, with and into
Litton. The purpose of the Litton merger is to acquire all shares of Litton
common stock not exchanged in the offer. At the effective time of the Litton
merger, each share of Litton common stock, except for Litton common stock held
by Litton, NNG or their subsidiaries, will be converted into the right to
receive the same amount of cash as is paid per share of Litton common stock in
the offer, subject to appraisal rights that may be available to Litton
stockholders under Delaware law and minus any required withholding of taxes and
without interest. Each share of Litton preferred stock not tendered or accepted
for payment in the offer will remain outstanding, without change, as a share of
Series B $2 Cumulative Preferred Stock of Litton, the corporation surviving the
Litton merger.

If two-thirds or more of the shares of Litton preferred stock are tendered
for purchase in the offer and NNG acquires such percentage of the Litton
preferred stock, NNG will have sufficient voting power to amend the terms of
the Litton preferred stock in accordance with the provisions set forth in
Litton's Restated Certificate of Incorporation. If, after the offer, there are
less than 300 registered holders of Litton preferred stock remaining, NNG
currently anticipates that it will deregister and delist the Litton preferred
stock from the NYSE, Northrop Grumman and NNG do not intend to redeem any
shares of Litton preferred stock that are not tendered and accepted by NNG for
purchase in the offer. However, following the Litton merger, NNG may seek to
acquire the shares of Litton preferred stock that remain outstanding for cash
at a price or prices not exceeding $35.00 per share through open market
transactions, an amendment to the Certificate of Incorporation of Litton, a
subsequent merger or otherwise.

See "Summary of Certain Statutory Provisions--Appraisal Rights" for
information concerning appraisal rights in the Litton merger.

Rule 13e-3 of the General Rules and Regulations under the Exchange Act would
require, among other things, that some financial information concerning Litton,
and some information relating to the fairness of the Litton merger and the
consideration offered to Litton stockholders, be filed with the SEC and
disclosed to Litton stockholders prior to consummation. Rule 13e-3 will not
apply to the Litton merger if it occurs within one year after the consummation
of the offer.

NNG reserves the right to acquire additional Litton stock through open
market purchases, privately negotiated transactions, a tender offer or exchange
offer, or otherwise following the consummation or termination of the offer,
upon such terms and at such prices as NNG decides, which may be more or less
favorable than those of the offer. NNG and its affiliates also reserve the
right to dispose of any or all shares of Litton stock acquired pursuant to the
offer or otherwise, upon such terms and at such prices as NNG determines.

Upon consummation of the offer, NNG intends to take appropriate actions to
optimize and rationalize the combined entities' assets, operations, management,
personnel, general and administrative functions and corporate structure. Other
than the Litton merger, NNG currently does not have any plans or proposals that
would result in an extraordinary corporate transaction, such as a merger,
reorganization or liquidation, or sale of a material amount of assets,
involving Litton or any of its subsidiaries, or any material changes in
Litton's corporate structure or business, or any change in its management.

Upon consummation of the offer, NNG may also elect or seek the election of
nominees of its choice to Litton's board of directors. Pursuant to the amended
merger agreement, until the merger is completed, Litton has agreed to use its
best efforts to ensure that at least three members of Litton's board of
directors as of January 23, 2001 remain members of Litton's board of directors.
See "The Amended Merger Agreement--The Litton Board."

Conditions of the Offer

Notwithstanding any other provisions of the offer relating to NNG's
obligation to accept for payment or exchange any tendered Litton common stock
or Litton preferred stock and subject to the terms and conditions of the
amended merger agreement and any applicable rules and regulations of the SEC,
including Rule 14e-1(c) under the Exchange Act, NNG shall not be required to
accept for payment or exchange or pay for or exchange, and may delay the
acceptance of, any shares of Litton stock, if:

(i) less than 25,646,399 shares of Litton common stock and Litton preferred
stock, which represent a majority of the total outstanding common stock
and preferred stock on a fully diluted basis, have been tendered
pursuant to the offer by the expiration of the offer and not withdrawn;

(ii) any applicable waiting period under the HSR Act or Regulation (EEC)
No. 4064/89 of the Council of the European Union shall not have
expired or been terminated prior to the expiration of the offer;

(iii) the registration statement relating to the offer shall not have
become effective under the Securities Act of 1933, as amended (the
"Securities Act"), or shall be the subject of any stop order or
proceeding seeking a stop order;

(iv) the shares of NNG common stock to be issued in the offer shall not
have been approved for listing on the NYSE, subject to official notice
of issuance; or

at any time on or after the date hereof and prior to the acceptance for payment
or exchange of Litton shares, any of the following conditions shall have
occurred and continued to exist:

(a) there shall have been any statute, rule, regulation, judgment, order
or injunction enacted or entered and which shall remain in effect by any
state or U.S. government or governmental authority or by any state, U.S. or
European Union court or any agency or authority of the European Union,
other than the routine application to the offer, the Northrop
reorganization and the Litton merger or other subsequent business
combination of waiting periods under the HSR Act or Regulation (EEC) No.
4064/89 of the Council of the European Union, that has the effect of (i)
making the acceptance for payment of, or the payment for, some or all of
the Litton shares illegal or otherwise prohibiting consummation of the
offer, (ii) imposing limitations on the ability of NNG or Northrop Grumman
to acquire or hold or to exercise effectively all rights of ownership of
the Litton shares, or to control effectively the business, assets or
operations of Northrop Grumman, Litton and their subsidiaries, of such
magnitude as would have a material adverse effect on the business, assets,
long-term earning capacity or financial condition of Northrop Grumman,
Litton and their subsidiaries, taken as a whole;

(b) a Company Material Adverse Effect, as defined in the amended merger
agreement, shall have occurred and continued to exist;

(c) there shall have occurred and continued to exist (i) any general
suspension of trading in, or limitation on prices for, securities on the
NYSE (excluding any coordinated trading halt triggered solely as a result
of a specified decrease in a market index and suspensions or limitations
resulting from physical damage to or interference with such exchange not
related to market conditions), (ii) the declaration of a banking moratorium
or any suspension of payments in respect of banks in the United States
(whether or not mandatory), (iii) the commencement of a war, armed
hostilities or other international or national calamity directly or
indirectly involving the United States and having a Company Material
Adverse Effect, (iv) any material limitation (whether or not mandatory) by
any U.S. governmental authority or agency on the extension of credit by
banks or other financial institutions, (v) from December 21, 2000 through
the date of termination or expiration of the offer, a decline of at least
27.5% in the Standard & Poor's 500 Index or (vi) in the case of any of the
situations described in clauses (i) through (v) inclusive, existing at the
date of the commencement of the offer, a material acceleration or worsening
thereof; or

(d) the amended merger agreement shall have been terminated in
accordance with its terms; or

(e) (i) the representations of Litton contained in the amended merger
agreement shall not be true and correct at and as of consummation of the
offer with the same effect as if made at and as of such date or if such
representations speak as of an earlier date, as of such earlier date,
except, in either such case to the extent that the breach thereof would not
have a Company Material Adverse Effect, or (ii) Litton shall have failed to
comply with its covenants and agreements contained in the amended merger
agreement in all material respects; or

(f) prior to the purchase of Litton shares pursuant to the offer, the
Litton board of directors shall have withdrawn or modified (including by
amendment of the Schedule 14D-9) in a manner adverse to NNG its approval or
recommendation of the offer, the merger agreement or the Litton merger or
shall have recommended another offer, or shall have adopted any resolution
to effect any of the foregoing.

Regulatory Approvals

Under the HSR Act and the rules that have been promulgated thereunder by the
Federal Trade Commission (the "FTC"), certain acquisition transactions may not
be consummated unless certain information has been furnished to the Antitrust
Division and the FTC and certain waiting period requirements have been
satisfied. The purchase of Litton common stock and Litton preferred stock
pursuant to the offer is subject to such requirements.

Pursuant to the requirements of the HSR Act, Northrop Grumman first filed a
Notification and Report Form with respect to the offer and Litton merger with
the Antitrust Division and the FTC on January 4, 2001. This filing was
voluntarily withdrawn on January 16, 2001 with the result that the statutory
waiting period requirement of 30 days applicable to the exchange offer began
again when the filing was resubmitted on January 31, 2001. The waiting period
applicable to the purchase of Litton common stock and Litton preferred stock
pursuant to the offer is scheduled to expire at 11:59 p.m., New York City time,
thirty days after such filing. However, prior to such time, the Antitrust
Division or the FTC may extend the waiting period by requesting additional
information or documentary material relevant to the offer from Northrop
Grumman. If such a request is made, the waiting period will be extended until
11:59 p.m., New York City time, on the thirtieth day after substantial
compliance by Northrop Grumman with such request, (or the next business day, if
such date falls on a weekend or holiday). Thereafter, such waiting period can
be extended only by court order.

Any extension of the waiting period will not give rise to any withdrawal
rights not otherwise provided for by applicable law. See "The Offer--Withdrawal
Rights" beginning on page 27. If NNG's purchase of Litton common stock or
Litton preferred stock is delayed pursuant to a request by the Antitrust
Division or the FTC for additional information or documentary material pursuant
to the HSR Act, the offer will be extended in

certain circumstances. See "The Amended Merger Agreement--Conditions to the
Completion of the Litton Merger."

The Antitrust Division and the FTC scrutinize the legality under the
antitrust laws of transactions such as the purchase of Litton common stock and
Litton preferred stock by NNG pursuant to the offer. At any time before or
after the consummation of any such transactions, the Antitrust Division or the
FTC could take such action under the antitrust laws of the United States as it
deems necessary or desirable in the public interest, including seeking to
enjoin the purchase of Litton common stock and/or Litton preferred stock
pursuant to the offer or seeking divestiture of the Litton common stock and/or
Litton preferred stock so acquired or divestiture of substantial assets of
Northrop Grumman or Litton. Private parties (including individual states) may
also bring legal actions under the antitrust laws of the United States. NNG
does not believe that the consummation of the offer will result in a violation
of any applicable antitrust laws. However, there can be no assurance that a
challenge to the offer on antitrust grounds will not be made, or if such a
challenge is made, what the result will be, including conditions with respect
to litigation and certain governmental actions. See "The Amended Merger
Agreement--Conditions to the Completion of the Litton Merger." See "The Amended
Merger Agreement--Termination Events" for certain termination rights.

The parties conduct business in a number of foreign countries. Under the
laws of certain foreign nations and multinational authorities, such as the
European Commission (under Council Regulation (EEC) 4064/89, or "ECMR"), the
transaction may not be completed or control may not be exercised unless certain
filings are made with these nations' antitrust regulatory authorities or
multinational antitrust authorities and these antitrust authorities approve or
clear closing of the transaction. Other foreign nations and multinational
authorities have voluntary and/or post-merger notification systems. The parties
have filed or intend to file shortly all non-United States pre-merger
notifications that they believe are required, including that required under the
ECMR. Should any other approval or action be required, the parties currently
contemplate that such approval or action would be sought. Although the parties
believe that they will obtain all material required regulatory approvals in a
timely manner, it is not certain that all such approvals will be received in a
timely manner or at all or that foreign or multinational antitrust authorities
will not impose unfavorable conditions for granting the required approvals.

Reduced Liquidity; Possible Delisting

The tender of Litton common stock and Litton preferred stock pursuant to the
offer will reduce the number of holders of Litton common stock and Litton
preferred stock and the number of shares of Litton common stock and Litton
preferred stock that might otherwise trade publicly and could adversely affect
the liquidity and market value of the remaining shares of Litton common stock
and Litton preferred stock held by the public. Litton common stock and Litton
preferred stock currently are listed and principally traded on the NYSE.
Depending on the number of shares of Litton common and Litton preferred stock
acquired in the offer, following consummation of the offer, Litton common stock
or Litton preferred stock may no longer meet the requirements of the NYSE for
continued listing. For example, published guidelines of the NYSE indicate that
the NYSE would consider delisting the outstanding Litton common stock and
Litton preferred stock if, among other things:

. the number of publicly held shares of Litton common stock or Litton
preferred stock (exclusive of holdings of officers, directors and members
of their immediate families and other concentrated holdings of 10% or
more) should fall below 600,000;

. the number of record holders of 100 or more shares of Litton common stock
or Litton preferred stock should fall below 1,200; or

. the aggregate market value of publicly held shares of Litton common stock
or Litton preferred stock should fall below $5,000,000.

According to Litton, as of November 30, 2000, there were approximately
45,518,647 shares of Litton common stock (excluding 2,734,083 shares of common
stock held in Litton's treasury) and 410,643 shares of Litton preferred stock
outstanding.

If the NYSE were to delist the Litton common stock or Litton preferred
stock, including after the exchange of Litton stock in the offer but prior to
the Litton merger, the market for Litton common stock or Litton preferred stock
could be adversely affected. It is possible that Litton's shares would be
traded on other securities exchanges or in the over-the-counter market, and
that price quotations would be reported by such exchanges, or through NASDAQ or
by other sources. However, the extent of the public market for Litton common
stock and Litton preferred stock and the availability of such quotations would
depend upon the number of holders and/or the aggregate market value of the
Litton common stock or Litton preferred stock remaining at such time, the
interest in maintaining a market in the Litton common stock or Litton preferred
stock on the part of securities firms, the possible termination of registration
of Litton stock under the Exchange Act, as described below, and other factors.

Status as "Margin Securities"

The Litton common stock and Litton preferred stock are presently "margin
securities" under the regulations of the Federal Reserve Board, which has the
effect, among other things, of allowing brokers to extend credit with such
stock as collateral. Depending on the factors similar to those described above
with respect to listing and market quotations, following consummation of the
offer, Litton common stock and Litton preferred stock stock may no longer
constitute "margin securities" for the purposes of the Federal Reserve Board's
margin regulations, in which event Litton common stock and Litton preferred
stock would be ineligible as collateral for margin loans made by brokers.

Registration Under The Exchange Act

Litton common stock and Litton preferred stock are currently registered
under the Exchange Act. Litton can terminate that registration upon application
to the SEC if the outstanding shares are not listed on a national securities
exchange and if there are fewer than 300 holders of record of Litton common
stock or Litton preferred stock, as the case may be. Termination of
registration of the Litton stock under the Exchange Act would reduce the
information that Litton must furnish to its stockholders and to the SEC and
would make certain provisions of the Exchange Act, such as the short-swing
profit recovery provisions of Section 16(b), the requirement of furnishing a
proxy statement in connection with stockholders meetings pursuant to Section
14(a) and the related requirement of furnishing an annual report to
stockholders, and the requirements of Rule 13e-3 (described above) no longer
applicable with respect to Litton stock that is no longer registered.
Furthermore, the ability of "affiliates" of Litton and persons holding
"restricted securities" of Litton to dispose of such securities pursuant to
Rule 144 under the Securities Act may be impaired or eliminated. In addition,
if registration of the shares under the Exchange Act were terminated, they
would no longer be eligible for NYSE listing or for continued inclusion on the
Federal Reserve Board's list of "margin securities."

Source and Amount of Funds

The offer is not conditioned upon any financing arrangements. NNG estimates
that the total amount of funds required to purchase all of the outstanding
Litton stock pursuant to the offer and the Litton merger and to pay related
fees and expenses will be between approximately $2.3 billion and $2.9 billion,
depending upon the actual number of shares of NNG common stock and NNG
preferred stock issued in the offer. NNG expects to obtain the funds necessary
to consummate the offer and the Litton merger from Northrop Grumman. Northrop
Grumman has received a commitment letter from Credit Suisse First Boston, The
Chase Manhattan Bank and JP Morgan providing for the structure, arrangement and
syndication of senior unsecured loans of up to $6,000,000,000, the initial
proceeds of which will be used solely to acquire Litton common stock and
preferred stock in the offer and the Litton merger, to retire and refinance
certain outstanding debt of Litton and to pay any related expenses. The
proceeds of subsequent borrowings under the loans will be used for general
corporate

purposes of NNG, Northrop Grumman and Litton. The loans will be in the form of
a 364-day revolving credit facility with an aggregate maximum principal amount
of $2,500,000,000, a five-year revolving credit facility with an aggregate
principal amount of up to $2,500,000,000 and a 364-day term facility with an
aggregate principal amount of $1,000,000,000. Each of the facilities will be an
unsecured senior credit facility and will contain usual and customary
affirmative and negative covenants, including customary financial covenants.
Interest rates for the loans will be adjusted LIBOR (which will at all times
include statutory reserves) or the adjusted base rate, at the election of
Northrop Grumman, in each case plus spreads depending upon a schedule of
certain specified Standard & Poor's and Moody's Investor Services ratings of
Northrop Grumman. Northrop Grumman may elect periods of one, two, three or six
months for adjusted LIBOR borrowings under the loans.

It is expected that the loan documents will be negotiated while the offer is
outstanding and signed on or before expiration of the offer.

Relationships with Litton

Except as set forth in this offer to purchase or exchange, neither NNG nor
Northrop Grumman nor, to the best of its knowledge, any of NNG's or Northrop
Grumman's directors or executive officers, has any contract, arrangement,
understanding or relationship with any other person with respect to any
securities of Litton, including, but not limited to, any contract, arrangement,
understanding or relationship concerning the transfer or the voting of any such
securities, finder's fees, joint ventures, loan or option arrangements, puts or
calls, guarantees of loans, guarantees against loss, guarantees of profits,
division of profits or loss or the giving or withholding of proxies.

Except as described in this offer to purchase or exchange, neither NNG nor
Northrop Grumman nor, to the best of its knowledge, any of NNG's or Northrop
Grumman's directors or executive officers, has had any business relationship or
transaction with Litton or any of its executive officers, directors or
affiliates that is required to be reported under the rules and regulation of
the SEC applicable to the offer. Except as described in this offer to purchase
or exchange, there have been no contracts, negotiations or transactions between
NNG and Northrop Grumman or to the best of its knowledge any of NNG's or
Northrop Grumman's directors or executive officers, on the one hand, and Litton
or its affiliates, on the other hand, concerning a merger, consolidation or
acquisition, a tender offer or other acquisition of securities, an election of
directors or a sale or other transfer of a material amount of assets.

In the normal course of their business, Northrop Grumman and Litton are
parties to transactions and agreements. During the two years ended October 31,
2000, no such transaction had an aggregate value in excess of 1% of Litton's
consolidated revenues.

Fees and Expenses

NNG has retained Georgeson Shareholder Communications Inc. to act as the
information agent in connection with the offer. The information agent may
contact holders of Litton stock by mail, telephone, telex, telegraph and
personal interviews and may request brokers, dealers and other nominee
stockholders to forward the offer materials to beneficial owners of Litton
stock. The information agent will be paid a customary fee for such services,
plus reimbursement of out-of-pocket expenses, and NNG will indemnify the
information agent against certain liabilities and expenses in connection with
the offer, including liabilities under federal securities laws.

Salomon Smith Barney Inc. is acting as the dealer manager in connection with
the offer and as financial advisor to NNG and Northrop Grumman in connection
with the offer and the Litton merger, for which services Salomon Smith Barney
Inc. will receive reasonable and customary compensation. Northrop Grumman has
agreed to reimburse Salomon Smith Barney Inc. for reasonable fees and expenses
incurred in performing its services, including reasonable fees and expenses of
its legal counsel and to indemnify Salomon Smith Barney Inc. and certain
related parties against certain liabilities, including liabilities under the
federal securities laws,

arising out of its engagement. In the ordinary course of business, Salomon
Smith Barney Inc. and its affiliates may actively trade or hold the securities
of Northrop Grumman, Litton and their respective affiliates for Salomon Smith
Barney's and its affiliates' own account or for the account of customers and,
accordingly, may at any time hold a long or short position in such securities.

NNG will not pay any fees or commissions to any broker, dealer or other

soliciting tenders of Litton stock pursuant to the offer. Brokers, dealers,
commercial banks and trust companies will, upon request, be reimbursed by NNG
for customary mailing and handling expenses incurred by them in forwarding
offering materials to their customers.

Merrill Lynch & Co. provided certain financial advisory services to Litton
in connection with the offer and the Litton merger, including providing an
opinion dated January 23, 2001 substantially to the effect that, as of such
date, the aggregate consideration to be received by holders of Litton common
stock, other than Northrop Grumman and its affiliates, pursuant to the amended
merger agreement is fair from a financial point of view to the holders of
Litton common stock. The opinion is attached as an exhibit to Litton's Schedule
14D-9, which is being mailed to the stockholders of Litton with this offer to
purchase or exchange.

BACKGROUND OF THE AMENDED MERGER AGREEMENT

In May 2000, Kent Kresa, Chairman and Chief Executive Officer of Northrop
Grumman, and Michael Brown, Chairman and Chief Executive Officer of Litton,
agreed that a small group of directors, officers and senior employees from the
two companies would have discussions looking into the possibility of a
strategic transaction. A confidentiality letter agreement was signed, dated
June 23, 2000 (the "confidentiality agreement"), by which each company agreed
to maintain the confidentiality of non-public information which might be
received from the other and also agreed that no disclosure would be made
concerning the discussions between the parties. From that time to the present a
number of meetings and conversations have taken place between representatives
of the two companies.

In mid-September 2000, Mr. Kresa contacted Mr. Brown to advise him that
Northrop Grumman would have an interest in acquiring Litton in a transaction in
which the holders of Litton common stock would receive a combination of cash
and stock having a value equivalent, on a per share basis, to 0.70 of a share
of Northrop Grumman common stock. Subsequent to the conversation, a
representative of Northrop Grumman was advised that Litton did not wish to
pursue the proposal.

On October 20, 2000, Litton publicly announced its intention to explore the
sale of its Advanced Electronics group. Later the same day, Mr. Kresa spoke
with Mr. Brown and wrote to him reiterating Northrop Grumman's interest in an
acquisition of Litton in a transaction involving cash and stock valued at 0.70
of a share of Northrop Grumman common stock, for each share of Litton common
stock. Mr. Kresa pointed out that the sale of the Advanced Electronics group
would be inconsistent with Northrop Grumman's plans for the combined company
and would diminish Northrop Grumman's interest in the combination. In response,
Mr. Brown advised Mr. Kresa that the transaction value proposed by Northrop
Grumman was not sufficient for Litton's board of directors to support such a
transaction.

On November 2, 2000, Mr. Kresa again wrote to Mr. Brown increasing the value
of Northrop Grumman's proposal so that holders of Litton common stock would
receive a combination of cash and Northrop Grumman common stock having a value
equivalent, on a per share basis, to 0.75 of a share of Northrop Grumman common
stock and offering the potential for some additional value to be delivered to
the holders of Litton common stock through a contingent value mechanism.

Following a meeting of the Litton board of directors on November 3, 2000,
Mr. Brown again advised Mr. Kresa that the value proposed by Northrop Grumman
was considered insufficient by the Litton board of directors. On November 29,
2000, Mr. Kresa wrote to Mr. Brown to specifically propose two alternatives for
a potential transaction. The first proposed alternative would provide Litton's
stockholders with a combination of cash and stock valued at 0.75 of a share of
Northrop Grumman common stock plus a contingent value instrument which would
provide the Northrop Grumman's stockholders with 75% of the net after-tax
recovery in Northrop Grumman's pending litigation with Honeywell, Inc. as well
as certain other litigation, and between 40% and 60% of the net after-tax value
of the Electronic Components and Materials business segment achieved within the
five-year period following closing. The second alternative proposed was for an
acquisition for cash at $72.00 per share of Litton common stock.

Following further discussions and negotiations and the exchange of
additional non-public information between the parties, the board of directors
of Northrop Grumman met on December 20, 2000 and unanimously approved the
merger agreement. The Litton board of directors met on December 21, 2000 and
also approved the merger agreement and determined unanimously that the
transactions contemplated thereby, including the offer and the Litton merger,
were fair to, and in the best interests of, the holders of Litton common stock.

On December 21, 2000, the merger agreement was executed by Northrop Grumman,
LII Acquisition and Litton, and Northrop Grumman and Litton issued a joint
press release announcing the transaction. On January 5, 2001, LII Acquisition
commenced an offer to purchase all of the Litton common stock and Litton
preferred stock for cash.

Following execution of the merger agreement on December 21, 2000
representatives of Litton and Northrop Grumman had a number of conversations
with representatives of Litton's largest stockholder, Unitrin. In those
conversations, Unitrin expressed its strong desire that the proposed
transactions be modified to provide a means for the exchange of Litton common
stock for stock of Northrop Grumman, or an affiliated company, on a tax-
deferred basis. On January 16, 2001, Northrop Grumman and Litton announced that
they were considering a possible amendment of the proposed transaction to
provide the means for a tax-free exchange of Litton common stock for capital
stock of Northrop Grumman following completion of the then-pending all cash
tender offer for Litton common stock at $80.00 per share in cash.

In the course of discussions among Litton, Northrop Grumman and Unitrin,
Litton advised of its willingness to consider alternative structures for the
transaction, provided that: (i) no stockholder who wanted cash would be
required to accept securities in the transaction; (ii) the restructured
transaction would be at least as certain to be completed as the original
transaction; (iii) it would not materially delay the time at which Litton
stockholders who wanted to sell their shares for cash would be paid; and (iv)
all holders of Litton common stock would be treated equally. The parties
considered a number of alternative possible structures for attaining the
desired objectives and finally determined that the amended merger agreement
accomplished their mutual objectives. The amended merger agreement, dated as of
January 23, 2001 was executed and delivered on January 24, 2001. At the same
time, Northrop Grumman and Unitrin executed and delivered a stockholder's
agreement, dated as of January 23, 2001. On January 24, 2001, Unitrin stated,
in a filing with the SEC, that it had agreed to tender its shares of Litton
common stock in the offer pursuant to the terms of the amended merger
agreement.

Certain Projections

Prior to entering into the amended merger agreement, Litton provided to
Northrop Grumman certain information which was not publicly available,
including a variety of projected financial data based on various differing
assumptions for future fiscal years. Litton has advised that it does not
publicly disclose projections, and the projections furnished to Northrop
Grumman were not prepared with a view to public disclosure. Northrop Grumman
analyzed the information in the projections, certain publicly available
information and additional information obtained in Northrop Grumman's due
diligence review of Litton, along with Northrop Grumman's own estimates of
potential cost savings and benefits in evaluating the offer and the Litton
merger.

Litton does not as a matter of course make public projections as to future
sales, earnings or other results. However, the management of Litton has
prepared the prospective financial information set forth below to assist
Northrop Grumman's management in assessing Litton's future financial
performance. The accompanying prospective financial information was not
prepared with a view toward public disclosure or with a view toward complying
with the guidelines established by the American Institute of Certified Public
Accountants with respect to prospective financial information. This information
is not fact and should not be relied upon as being necessarily indicative of
future results, and Litton stockholders are cautioned not to place undue
reliance on the prospective financial information.

Neither Litton's nor Northrop Grumman's independent auditors, nor any other
independent accountants, have compiled, examined or performed any procedures
with respect to the prospective financial information contained herein, nor
have they expressed any opinion or any other form of assurance on such
information or its achievability, and assume no responsibility for, and
disclaim any association with, the prospective financial information.

The projections provided to Northrop Grumman by Litton included, among other
things, the following forecasts of Litton's revenues, net income (excluding
pension income) and earnings per share (excluding

pension income), respectively (in millions, except per share data): $5,850.0,
$151.9 and $3.31 in 2001; $6,473.0, $186.4 and $4.06 in 2002; $6,827.0, $220.8
and $4.81 in 2003; $7,183.0, $248.4 and $5.41 in 2004; and $7,436.0, $278.7,
and $6.07 in 2005. Including pension income, the projected net income and
earnings per share were, respectively (in millions, except per share data):
$220.5 and $4.80 in 2001; $254.9 and $5.55 in 2002; $289.4 and $6.30 in 2003;
$317.0 and $6.90 in 2004; and $347.3 and $7.56 in 2005.

Other projections provided to Northrop Grumman by Litton indicated the
potential for increased profitability based upon more aggressive assumptions.
Based upon the more aggressive assumptions, these projections indicated
revenues and net income (including pension income), respectively (in millions),
of: $6,019.0 and $228.0 in 2001; $6,740.0 and $300.0 in 2002; $7,329.0 and
$414.0 in 2003; $7,920.0 and $490.0 in 2004; and $8,426.0 and $548.0 in 2005.
Litton has advised Northrop Grumman that these projections do not give effect
to customary processes of adjustment by senior management of projections
provided by operating/divisional management.

The projections are forward-looking statements that are subject to certain
risks and uncertainties that could cause actual results to differ materially
from those statements and should be read with caution. The projections are
subjective in many respects and thus susceptible to interpretations and
periodic revisions based on actual experience and recent developments. While
presented with numerical specificity, the projections were not prepared by
Litton in the ordinary course and are based upon a variety of estimates and
hypothetical assumptions made by management of Litton with respect to, among
other things, industry performance, general economic, market, interest rate and
financial conditions, sales, cost of goods sold, operating and other revenues
and expenses, capital expenditures and working capital of Litton, and other
matters which may not be realized and are inherently subject to significant
business, economic and competitive uncertainties and contingencies, all of
which are difficult to predict and many of which are beyond Litton's control.
Litton's operations are subject to various additional risks and uncertainties
resulting from its position as a supplier, either directly or as subcontractor
or team member, to the United States government and its agencies as well as to
foreign governments and agencies; actual outcomes are dependent upon factors,
including, without limitation, Litton's successful performance of internal
plans; government customers' budgetary restraints; customer changes in short-
range and long-range plans; domestic and international competition in both the
defense and commercial areas; product performance; continued development and
acceptance of new products; performance issues with key suppliers and
subcontractors; government import and export policies; acquisition or
termination of government contracts; the outcome of political and legal
processes; legal, financial, and governmental risks related to international
transactions and global needs for military aircraft, military and civilian
electronic systems and support and information technology. Accordingly, there
can be no assurance that the assumptions made in preparing the projections will
prove accurate, and actual results may be materially greater or less than those
contained in the projections. In addition, the projections do not take into
account any of the transactions contemplated by the amended merger agreement,
including the offer and the Litton merger. These events may cause actual
results to differ materially from the projections.

For these reasons, as well as the bases and assumptions on which the
projections were compiled by Litton, the inclusion of such projections herein
should not be regarded as an indication that Litton, Northrop Grumman, NNG or
any of their respective affiliates or representatives considers such
information to be an accurate prediction of future events, and the projections
should not be relied on as such. None of such persons assumes any
responsibility for the reasonableness, completeness, accuracy or reliability of
such projections. No party nor any of their respective affiliates or
representatives has made, or makes, any representation to any person regarding
the information contained in the projections and none of them intends to update
or otherwise revise the projections to reflect circumstances existing after the
date when made or to reflect the occurrences of future events even in the event
that any or all of the assumptions are shown to be in error.

Reasons for the Offer and the Litton Merger

Northrop Grumman believes that the proposed acquisition of Litton by means
of the offer and the Litton merger will produce the following benefits:

. Access to New Product Areas. Litton's proprietary technology and products
will provide NNG with technology and products to complement Northrop
Grumman's existing technology and products.

. Increased Diversification into New Markets. The combination of Northrop
Grumman and Litton under NNG provides the affiliated entities with the
opportunity for diversification into new markets and access to new
customers.

. Increased Market Presence and Opportunities. The combination of Northrop
Grumman and Litton under NNG provides the affiliated entities with
increased market presence and opportunities for growth that could allow
them to be better able to respond to the needs of customers, the
increased competitiveness of the marketplace and opportunities that
changes in the market for their respective products might bring.

. Product Mix. The complementary nature of Northrop Grumman's and Litton's
products and services will benefit clients of both companies.

. Operating Efficiencies. The combination of Northrop Grumman and Litton
under NNG provides the opportunity for potential economies of scale and
cost savings.

The reasons for the Litton board's recommendation are set forth in Litton's
Solicitation/Recommendation Statement on Schedule 14D-9 which is being mailed
to Litton stockholders together with this offer to purchase or exchange.

MATERIAL FEDERAL INCOME TAX CONSEQUENCES

The following is a summary of the material federal income tax consequences
that will apply to the following Litton stockholders:

. holders of Litton common stock who tender their shares for cash, NNG
common stock or NNG preferred stock (or a combination thereof) pursuant
to the offer;

. holders of Litton preferred stock who tender their shares for cash
pursuant to the offer; and

. holders of Litton common stock who receive cash in the Litton merger.

The following discussion does not address any aspect of state, local or
foreign taxation. It also does not address all aspects of federal income
taxation that may be important to particular taxpayers in light of their
personal investment circumstances or to taxpayers subject to special treatment
under the federal income tax laws including:

. life insurance companies;

. foreign persons;

. banks or other financial institutions;

. tax-exempt entities;

. dealers in securities;

. employee benefit plans;

. persons that hold such shares as part of a straddle, a hedge against
currency risk or as a constructive sale or conversion transaction; and

. persons who acquired their Litton common stock or Litton preferred stock
pursuant to the exercise of employee stock options or otherwise as
compensation.

This summary is based upon the provisions of the Internal Revenue Code of
1986, as amended (the "Code"), applicable Treasury Regulations thereunder,
judicial decisions, and current administrative rulings. No rulings have been or
will be requested from the Internal Revenue Service with respect to any of the
matters discussed herein, and the opinion of counsel described below is not
binding on the Internal Revenue Service. Neither the delivery of the opinion of
counsel described below, nor the delivery of any other tax opinion, is a
condition to closing the offer or the Litton merger. There can be no assurance
that future legislation, regulations, administrative rulings or court decisions
will not adversely affect the accuracy of the statements contained in this
summary.

It is the opinion of Gibson, Dunn & Crutcher LLP, counsel for Northrop
Grumman, and Ivins, Phillips & Barker Chartered, special tax counsel to
Northrop Grumman, that the exchange of Litton common stock for NNG common
stock, NNG preferred stock and cash will be treated together with the Northrop
reorganization and the Litton merger as a transaction governed by Section
351(a) or Section 351(b) of the Code and that this discussion accurately sets
forth the material federal income tax consequences of the transaction. Such
opinions are based upon, among other things, a representation letter and other
information provided by Northrop Grumman to counsel.

The discussion below also reflects the opinion of Gibson, Dunn & Crutcher
LLP and Ivins, Phillips & Barker Chartered that the NNG preferred stock will
not be "nonqualified preferred stock." Under Section 351(g) of the Code,
enacted in 1997, "nonqualified preferred stock" is treated as taxable "boot" in
a Section 351 transaction. Since this provision is recent and since
implementing regulations have not yet been promulgated, the Internal Revenue
Service could take a position contrary to that expressed in the opinions of
counsel. In such an event, holders of Litton common stock who receive NNG
preferred stock would be taxed as though they had received cash equal to the
fair market value of the NNG preferred stock. The discussion below is based on
the conclusion that the NNG preferred stock will not be nonqualified preferred
stock.

Treatment of Holders of Litton Common Stock Who Tender Their Stock in the
Offer

The discussion below assumes that all holders of Litton common stock hold
their stock as capital assets.

Exchange of Litton Common Stock Solely for Cash

A holder of Litton common stock who receives solely cash in exchange for
Litton common stock pursuant to the offer will recognize capital gain or loss
equal to the difference between the tax basis of the Litton common stock
surrendered and the amount of cash received therefore. That capital gain or
loss will constitute long-term capital gain or loss if the Litton common stock
has been held by the holder for more than one year on the date of closing of
the offer. Gain or loss must be calculated separately for each block of Litton
common stock (i.e., shares of stock acquired at the same time in a single
transaction).

Exchange of Litton Common Stock Solely for NNG Common Stock and/or NNG
Preferred Stock

Except as discussed below under "--Cash in Lieu of Fractional Shares," a
holder of Litton common stock who receives solely NNG common stock or NNG
preferred stock, or some of each, in exchange for Litton common stock pursuant
to the offer will not recognize gain or loss upon such exchange.

The aggregate tax basis of the NNG common stock and NNG preferred stock
received by the holder will be equal to the aggregate tax basis of the Litton
common stock surrendered (excluding any portion of the holder's basis
allocated to fractional shares). If a holder receives both NNG common stock
and NNG preferred stock, the holder's basis in his shares of Litton common
stock will be allocated to the shares of each class of stock received in
proportion to the fair market value of each class.

The holding period of the NNG common stock and NNG preferred stock will
include the holding period of the Litton common stock surrendered.

A holder of Litton common stock who is considering making an election to
receive NNG common stock or NNG preferred stock in the exchange should note
that there can be no assurance that such holder will receive only NNG common
stock or NNG preferred stock (because of the possibility of proration). Such
stockholders may receive some cash. Accordingly, there can be no assurance
that a holder who makes such an election will recognize no taxable gain upon
such holder's exchange of Litton common stock.

Exchange of Litton Common Stock for a Combination of Cash and NNG Common
Stock or NNG Preferred Stock or Some of Each

Except as discussed below under "--Cash in Lieu of Fractional Shares," a
holder of Litton common stock who receives a combination of cash and either
NNG common stock, NNG preferred stock, or some of each, in exchange for Litton
common stock (by reason of the elections made by the holder or by the
application of the proration procedures) will not recognize any loss realized
in the transaction but will recognize some capital gain, if any gain is
realized. The amount of capital gain recognized will be calculated separately
for each block of Litton common stock surrendered, in an amount equal to the
lesser of

. the amount of gain realized in respect of the block (i.e., the excess of
(a) the sum of the amount of cash and the fair market value of NNG common
stock and NNG preferred stock received that is allocable to the block
over (b) the tax basis of the block); and

. the amount of cash received that is allocable to the block.

For this purpose, all of the cash, NNG common stock and NNG preferred stock
received by a holder will be allocated in proportion to fair market values
among the blocks of Litton common stock surrendered by such holder.

Any capital gain will constitute long-term capital gain if the block of
Litton common stock has been held for more than one year on the date of
closing of the offer.

The aggregate tax basis of the NNG common stock and NNG preferred stock
received in exchange for a block of Litton common stock will be equal to the
tax basis of the surrendered block of Litton common stock, decreased by the
amount of cash received in respect of the block and increased by the amount of
gain recognized in respect of the block. If a holder receives both NNG common
stock and NNG preferred stock, the holder's basis will be allocated to the
shares of each class of stock received in proportion to the fair market value
of each class.

The holding period of the NNG common stock and NNG preferred stock will
include the holding period of the block of Litton common stock surrendered.

Federal Income Tax Considerations in Making an Election

A holder of Litton common stock who elects to receive cash pursuant to the
offer will not be subject to any proration. However, holders who elect to
receive NNG common stock or NNG preferred stock pursuant to the offer might
receive cash as a result of the proration procedures. Thus, the actual federal
income tax consequences to each Litton shareholder electing to receive NNG
common stock or NNG preferred stock will not be ascertainable at the time the
election is made because the extent to which the proration procedures will
apply to those elections will not be known.

Cash in Lieu of Fractional Shares

A holder of Litton common stock who receives cash in lieu of fractional
shares of NNG common stock or NNG preferred stock will be treated as having
received such fractional shares at the closing of the offer and then as having
exchanged such fractional shares for cash in a redemption by NNG. Any gain or
loss attributable to fractional shares generally will be capital gain or loss.
The amount of such gain or loss will be equal to the difference between the
ratable portion of the tax basis of the Litton common stock surrendered in the
exchange that is allocated to such fractional shares and the cash received in
lieu thereof. Any such capital gain or loss will constitute long-term capital
gain or loss if the Litton common stock surrendered has been held by the
holder for more than one year on the date of closing of the offer.

Treatment of Holders of Litton Preferred Stock Who Tender Their Litton
Preferred Stock in the Offer

The following discussion assumes that all holders of Litton preferred stock
hold their stock as capital assets. A holder of Litton preferred stock who
participates in the offer will receive solely cash for the Litton preferred
stock tendered.

Holders of Litton Preferred Stock Who Hold No Litton Common Stock

A holder of Litton preferred stock who does not hold any Litton common
stock and who participates in the offer will recognize capital gain or loss
equal to the difference between the tax basis of the Litton preferred stock
surrendered and the amount of cash received in the exchange. Such capital gain
or loss will constitute long-term capital gain or loss if the Litton preferred
stock has been held by the holder for more than one year on the date of
closing of the offer. Gain or loss must be calculated separately for each
block of Litton preferred stock (i.e., shares acquired at the same time in a
single transaction).

Holders of Litton Preferred Stock Who Also Hold Litton Common Stock That is
Tendered in the Offer

A holder of Litton preferred stock who also holds Litton common stock and
who participates in the offer will be taxed according to the rules described
above for holders of Litton common stock who tender their stock in the offer.
The cash received for any Litton preferred stock will be treated the same as
cash received for Litton common stock.

Treatment of Holders of Litton Common Stock in the Litton Merger

The following discussion assumes that all holders of Litton common stock
hold their stock as capital assets. Holders of Litton common stock who do not
tender their stock pursuant to the offer will receive solely cash for their
Litton common stock in the Litton merger.

Holders of Litton Common Stock Who Tender No Stock in the Offer

A holder of Litton common stock who does not tender any stock in the offer
will receive cash in the Litton merger. Such a holder will recognize capital
gain or loss equal to the difference between the tax basis of the Litton common
stock surrendered in the Litton merger and the amount of cash received
therefore. Such capital gain or loss will constitute long-term capital gain if
the Litton common stock has been held by the holder for more than one year at
the effective time of the merger. Gain or loss must be calculated separately
for each block of Litton common stock (i.e., shares acquired at the same time
in a single transaction).

Holders of Litton Common Stock Who Tender Litton Common Stock in the Offer

A holder of Litton common stock who tenders some (but not all) of that
common stock in the offer will receive cash in the Litton merger for any Litton
common stock that is not tendered in the offer. Such a holder will be taxed
according to the rules described above for holders of Litton common stock who
tender all their stock in the offer. The cash received in the Litton merger
will be treated the same as cash received for Litton common stock tendered in
the offer (except that the holding period for stock surrendered in the Litton
merger will end on the merger effective date rather than the closing date of
the offer).

Reporting Requirements

Each holder of Litton common stock that receives NNG common stock or NNG
preferred stock pursuant to the offer will be required to retain records and
file with such holder's federal income tax return a statement setting forth
certain facts relating to the Litton merger. The statement and such records
must include, among other things, the adjusted tax basis and number of shares
of Litton common stock which you transfer pursuant to the offer and the number
of shares and fair market value of the NNG common stock and NNG preferred stock
received.

This federal income tax discussion is for general information only and may
not apply to all holders of Litton common stock and Litton preferred stock.
Litton stockholders are urged to consult their own tax advisors as to the
specific tax consequences of the offer and the Litton merger.

THE AMENDED MERGER AGREEMENT

The amended merger agreement is filed as an exhibit to the registration
statement of which this offer to purchase or exchange is a part and is
incorporated by reference herein. The following summary describes the material
terms of the amended merger agreement. However, the legal rights and
obligations of the parties are governed by the specific language of the amended
merger agreement, and not this summary.

The amended merger agreement sets forth the principal terms of the offer,
including:

. the consideration offered;

. the exchange ratio for exchanging Litton common stock for NNG common
stock and NNG preferred stock;

. terms and conditions of the NNG preferred stock;

. the elections available to tendering stockholders;

. the procedures for pro rata reduction of elections to receive NNG stock
if required because of the limited amounts of NNG common stock and NNG
preferred stock available; and

. the conditions to the offer.

The amended merger agreement prohibits NNG from taking any of the following
actions without the prior written consent of Litton:

. any decrease in the amount of cash or stock consideration offered per
share of Litton common or preferred stock;

. any change in the form of consideration payable in the offer;

. any decrease in the number of shares of common or preferred sought in the
offer, except as disclosed under "The Offer--Possible Reduction in Number
of Shares of NNG Common Stock";

. the imposition of additional conditions in the offer;

. an amendment of the offer in a manner adverse to the holders of Litton
common or preferred stock;

. any reduction in the time in which the offer will remain open; or

. any waiver of the minimum tender condition.

The Northrop Reorganization

Immediately prior to the acceptance for purchase and exchange of Litton
common and Litton preferred stock in the offer, a wholly-owned subsidiary of
NNG will merge with and into Northrop Grumman, in order that Northrop Grumman
will become a wholly-owned subsidiary of NNG. That merger is referred to as the
"Northrop reorganization."

In the Northrop reorganization, all of the outstanding shares of capital
stock of Northrop Grumman will become the same number of shares of the same
class of capital stock of NNG. Outstanding options to acquire common stock of
Northrop Grumman will become options to acquire common stock of NNG. The
certificate of incorporation and bylaws of NNG will be identical, in all
material respects, to the certificate of incorporation and bylaws of Northrop
Grumman, and NNG will adopt a stockholder rights plan which is identical, in
all material respects, to the stockholder rights plan of Northrop Grumman. The
directors and officers of Northrop Grumman will constitute the board of
directors and officers of NNG.

Upon completion of the Northrop reorganization, the name of NNG will be
changed to "Northrop Grumman Corporation" and the name of the present Northrop
Grumman Corporation will be changed to "Northrop Grumman Operations
Corporation."

The common stock of Northrop Grumman following the Northrop reorganization
(i.e. the NNG common stock) will be listed for trading on the NYSE, and
certificates representing shares of Northrop Grumman common stock will continue
to represent shares of common stock of Northrop Grumman Corporation.

No vote of the stockholders of Northrop Grumman is required for the Northrop
reorganization.

The Litton Merger

At the effective time of the Litton merger, LII Acquisition will merge with
and into Litton. Litton will survive the Litton merger as a wholly-owned
subsidiary of NNG.

Conditions to the Completion of the Litton Merger

The Litton merger is subject to the satisfaction or waiver of the following
conditions:

. if required by Delaware law, the Litton stockholders must have approved
and adopted the amended merger agreement;

. no statute, rule, regulation, executive order, decree, ruling or
injunction must have been enacted, entered, promulgated, or enforced by
any U.S. court or U.S. or European Union governmental entity prohibiting,
restraining or enjoining consummation of the Litton merger;

. the expiration or termination of the applicable waiting period under the
HSR Act, approval of the Litton merger by the Commission of the European
Union under Regulation (EEC) No. 4064/89 of the Council of the European
Union; and

. NNG must have purchased Litton common stock in the offer.

Effective Time of the Litton Merger

The Litton merger will become effective upon the filing of a certificate of
merger with the Delaware Secretary of State or such later time as is mutually
agreed by Northrop Grumman and Litton and is permissible in accordance with the
DGCL. The filing of the certificate of merger will take place as soon as
practicable after the closing of the Litton merger.

Additional Effects of the Litton Merger and the Northrop Reorganization

Upon completion of the Litton merger:

. each share of common stock held as treasury stock by Litton or its
subsidiaries or owned by NNG or its subsidiaries will be canceled without
payment;

. each outstanding share of capital stock of LII Acquisition will be
converted into one share of common stock of Litton, as the surviving
corporation;

. each issued and outstanding share of Litton common stock will be
converted into the right to receive the highest amount of cash equal to
the per share amount of cash received by holders of Litton common stock
who tendered their shares for cash in the offer;

. each issued and outstanding share of Litton preferred stock, other than
shares of Litton preferred stock held by NNG, will remain outstanding,
without any change, as a share of preferred stock of Litton as the
surviving corporation;

. each outstanding share of Litton preferred stock held by NNG will be
canceled;

. the directors of LII Acquisition will become the directors of Litton as
the corporation surviving the Litton merger;

. the officers of Litton at the effective time of the Litton merger will
become the officers of Litton as the corporation surviving the merger;

. the certificate of incorporation of Litton, as in effect immediately
prior to the effective time of the Litton merger, will be amended as of
the effective time of the Litton merger to provide that Litton will be
authorized to issue 3,000,000 shares of common stock, par value $1.00 per
share, 600,000 shares of preferred stock, par value $5.00 per share, and
1,000 shares of preference stock, par value, $2.50 per share, and, as so
amended, such certificate of incorporation will be the certificate of
incorporation of Litton as the corporation surviving the Litton merger;
and

. the bylaws of Litton at the effective time of the Litton merger will
become the bylaws of Litton as the corporation surviving the Litton
merger.

Upon completion of the Northrop reorganization:

. the directors and officers of Northrop Grumman prior to the Northrop
reorganization will be the directors and officers of both Northrop
Grumman and NNG after the Northrop reorganization;

. the certificate of incorporation of Northrop Grumman, as in effect
immediately prior to the effective time of the Northrop reorganization,
will be amended as of the effective time of the reorganization to change
Northrop Grumman's name to "Northrop Grumman Operations Corporation" and
to specify that any act or transaction by or involving Northrop Grumman
that requires the approval of the stockholders of Northrop Grumman will
also require the approval of the stockholders of NNG and, as so amended,
such certificate of incorporation will be the certificate of
incorporation of Northrop Grumman as the corporation surviving the
reorganization;

. the bylaws of Northrop Grumman at the effective time of the
reorganization will become the bylaws of Northrop Grumman as the
corporation surviving the Northrop reorganization; and

. the certificate of incorporation and bylaws of NNG immediately following
the effective time of the Northrop reorganization will contain provisions
identical to the certificate of incorporation and bylaws of Northrop
Grumman immediately prior to the effective time of the Northrop
reorganization, except that the name of NNG will be changed to "Northrop
Grumman Corporation."

The Litton Board

Upon the purchase of Litton common stock in the offer, NNG will be entitled
to designate a number of Litton directors, constituting at least a majority of
the Litton board, equal to the product of the number of Litton directors and
the percentage that the number of shares of Litton common stock then held by
NNG bears to the total number of outstanding Litton shares. Until the effective
time of the Litton merger, Litton has agreed to use its best efforts to ensure
that at least three members of Litton's board of directors as of January 23,
2001 remain members of Litton's board of directors. The amended merger
agreement provides that, before the effective time of the Litton merger, if NNG
designees are elected to the Litton board, the affirmative vote of a majority
of the continuing Litton directors will be required to:

. amend or terminate the amended merger agreement;

. waive any of Litton's rights under the amended merger agreement;

. extend the time for performance of Northrop Grumman's, NNG's or LII
Acquisition's obligations under the amended merger agreement; or

. approve any other action by Litton adversely affecting the rights of
Litton's stockholders, other than Northrop Grumman, NNG or LII
Acquisition, with respect to the transactions contemplated by the amended
merger agreement.

Litton Stock Options

The amended merger agreement provides that each outstanding option to
purchase shares of Litton common stock that is vested at the effective time of
the Litton merger will be converted into the right to receive a cash payment
equal to the difference between the exercise price per share of Litton common
stock subject to the option and $80.00.

At the effective time of the Litton merger, each of up to 1,244,523
outstanding options to purchase shares of Litton common stock that is unvested
will become an option to purchase shares of NNG common stock. Any unvested
options in excess of 1,244,523 will be converted pro rata into the right to
receive a cash payment equal to the difference between the exercise price per
share of Litton common stock subject to the option and $80.00 and subject to
compliance with Section 424 of the Code.

NNG may provide holders of vested options and holders of unvested options
whose options would be converted into cash, the opportunity to elect, prior to
the Litton merger, to convert their options into options to acquire NNG common
stock on a pro rata basis. If NNG provides these optionholders with the
election, conversion will be allowed only to the extent a vote of Northrop
Grumman's or NNG's stockholders would not be required pursuant to applicable
law or the rules of any national securities exchange.

At the effective time of the Litton merger each outstanding share of
restricted stock will vest and holders of shares of restricted stock will have
the right to receive a cash payment equal to $80.00 per share or any greater
cash amount paid per share of Litton common stock in the offer.

For more information on the treatment of Litton stock options in connection
with the offer and the Litton merger, please refer to Item 4 of Litton's
Amended Solicitation/Recommendation Statement on Schedule 14D-9 which is being
mailed to Litton stockholders together with this offer to purchase or exchange.

Conduct of Business of Northrop Grumman and NNG Prior to the Litton Merger

The amended merger agreement contains restrictions on Northrop Grumman's,
its subsidiaries' and NNG's conduct of their respective businesses pending the
effective time of the Litton merger or the termination of the amended merger
agreement. These restrictions are designed to prevent major changes in Northrop
Grumman and NNG until the Litton merger takes place, except to the extent
Litton consents to the changes. In general, Northrop Grumman and NNG have
agreed that neither Northrop Grumman nor its subsidiaries nor NNG will:

. acquire or agree to acquire any entity if such transaction would prevent
or materially delay the consummation of the offer, the Litton merger or
the Northrop reorganization, other than the purchase of assets from
suppliers, clients or vendors in the ordinary course of business;

. amend their governing documents if such amendment would have a material
adverse impact on the consummation of the offer, the Litton merger or the
Northrop reorganization;

. take any action that would prevent the offer, the Litton merger and the
Northrop reorganization, taken together, from qualifying as an exchange
described in Section 351 of the Code;

common stock;

. adopt a plan of complete or partial liquidation or dissolution of
Northrop Grumman or any of its material subsidiaries; or

. take or agree to take any of the foregoing actions.

Other Potential Acquirers

The amended merger agreement prohibits Litton and its subsidiaries,
officers, directors, employees, representatives and agents from providing non-
public information to, or having discussions or negotiations

with, anyone other than Northrop Grumman, NNG or LII Acquisition with respect
to a potential third party acquisition of Litton, unless:

. Litton's board of directors receives an unsolicited proposal from a third
party. In this case Litton or its representatives may make such inquiries
or conduct such discussions as the Litton board of directors, based on
the advice of its legal counsel, may deem necessary to inform itself for
the purpose of exercising its fiduciary duties; or

. Litton's board of directors receives an unsolicited proposal from a third
party that Litton's board of directors by a majority vote decides in good
faith, after consultation with its financial advisor, is reasonably
likely to be a "superior proposal" (as defined below). In this case
Litton and its representatives may conduct such additional discussions or
provide such information as Litton's board of directors shall decide, if
the third party enters into a confidentiality agreement with terms
similar to the confidentiality agreement between Litton and Northrop
Grumman and a majority of Litton's board of directors decides in good
faith, based on the advice of its legal counsel, that its actions are
necessary to comply with Litton's board of directors' fiduciary duties.

The amended merger agreement does not prohibit Litton's board of directors
from taking and disclosing to Litton's stockholders a position contemplated by
Rules 14d-9 and 14e-2 under the Exchange Act with regard to any tender offer.

Litton's board of directors has agreed not to withdraw, change or modify its
recommendation of the offer and the Litton merger or approve or recommend any
third party acquisition, or cause Litton to enter into any agreement for a
third party acquisition, unless a majority of Litton's board of directors
decides in good faith, after consultation with and based upon the advice of its
legal counsel, that it is required to do so in order to comply with its
fiduciary duties, in which case the Litton board of directors may withdraw its
recommendation of the offer and the Litton merger and approve or recommend a
superior proposal if:

. Litton has provided written notice to Northrop Grumman specifying the
material terms, conditions and identity of the person making the superior
proposal; and

. Northrop Grumman has not made an equally favorable proposal within five
business days of Northrop Grumman's receiving notice of a superior
proposal.
However, Litton may not enter into an agreement with respect to a superior
proposal until the amended merger agreement is terminated and Litton has paid
Northrop Grumman a termination fee in the amount of $110,000,000 as liquidated
damages simultaneously with such termination. See "--The Amended Merger
Agreement--Termination Fee; Expenses" on page 59.

The amended merger agreement defines a "third party acquisition" to mean any
of the following:

. the acquisition of Litton by merger or otherwise by a party other than
Northrop Grumman, LII Acquisition or any of their affiliates;

. the acquisition of 20% of more of the assets of Litton and its
subsidiaries taken as a whole by a party other than Northrop Grumman, LII
Acquisition or any of their affiliates;

. the acquisition of 20% or more of the outstanding Litton common stock by
a party other than Northrop Grumman, LII Acquisition or any of their
affiliates;

. Litton's adoption of a plan of liquidation or the declaration or payment
of an extraordinary dividend;

. the repurchase of more than 20% of its outstanding common stock by Litton
or any of subsidiaries; or

. Litton's acquisition by merger, purchase of stock or assets, joint
venture or otherwise of a direct or indirect ownership interest or
investment in any business whose annual revenues, net income or assets is
equal to or greater than 20% of the annual revenues, net income or assets
of Litton.

The amended merger agreement defines a "superior proposal" as any bona fide
proposal:

. to acquire 50% or more of the common stock of Litton or substantially all
the assets of Litton for cash and/or securities; and

. that is determined by the Litton board of directors by a majority vote,
based on the advice of its financial advisor, to be more favorable, from
a financial point view, to Litton's stockholders than the Litton merger.

Litton has agreed to promptly advise Northrop Grumman of any request for
information relating to a third party acquisition proposal or any inquiry
relating to or which could result in a third party acquisition proposal,
including the terms, conditions and the identity of the person submitting the
third party proposal. Litton has also agreed to inform Northrop Grumman of the
status and any developments regarding any third party acquisition proposal.

Litton Stockholders Meeting

If required by applicable law to complete the Litton merger, the amended
merger agreement requires Litton as soon as practicable after consummation of
the offer to call a meeting of its stockholders to consider and vote upon the
adoption and approval of the amended merger agreement and to prepare and file
with the SEC a proxy statement. Under the amended merger agreement, at any such
meeting, Northrop Grumman, NNG and their subsidiaries have agreed to vote all
Litton shares acquired in the offer or otherwise beneficially owned by them in
favor of adoption of the amended merger agreement.

Litton's board of directors may withdraw, modify or amend its recommendation
that Litton common stockholders accept the offer and that Litton stockholders
approve and adopt the amended merger agreement and the Litton merger if:

. Litton receives a superior proposal; and

. Litton's board of directors determines in its good faith judgment by a
majority vote, based on the advice of its legal counsel, that it is
required to recommend the superior proposal to comply with its fiduciary
duties.

Litton has also agreed to use all reasonable efforts to:

. obtain and provide the information required to be included in the proxy
statement;

. respond promptly to any comments from the SEC concerning the proxy
statement, after consultation with Northrop Grumman and NNG;

. mail the proxy statement to Litton's stockholders as soon as possible
after the expiration or termination of the offer; and

. obtain the necessary approvals of Litton's stockholders of the amended
merger agreement.

Access to Information and Confidentiality

Litton has agreed to give Northrop Grumman and its representatives, and
Northrop Grumman and its representatives have agreed to:

. give Litton reasonable access during normal business hours to all
employees, plants, offices, warehouses and other facilities;

. give Litton reasonable access during normal business hours to all books
and records of itself and its subsidiaries;

. to furnish the other party with financial and operating data and such
other information concerning its business and properties and those of its
subsidiaries as may be reasonably requested; and

. to permit the other party to make inspections as may be reasonably
required.

Confidentiality

The amended merger agreement provides that Litton is not required to provide
certain confidential information. Litton and Northrop Grumman have entered into
a confidentiality agreement relating to all documents and information provided
to the other party in connection with the offer, the Litton merger and the
Northrop reorganization.

Additional Agreements

Each of Litton, Northrop Grumman, NNG and LII Acquisition has agreed to:

Directors' and Officers' Liability Insurance and Indemnification

The amended merger agreement provides that Northrop Grumman and Litton, as
the surviving corporation in the Litton merger, will jointly and severally
indemnify and hold harmless the current and former directors and officers of
Litton or any of its subsidiaries against:

. all losses, claims, damages, costs, expenses, settlement payments or
liabilities arising out of or in connection with any claim, demand,
action, suit, proceeding or investigation based in whole or in part on or
arising in whole or in part out of the fact that such person is or was an
officer or director of Litton or any of its subsidiaries whether or not
pertaining to any matter existing or occurring at or prior to the
effective time of the Litton merger and whether or not asserted or
claimed prior to or at or after the effective time of the Litton merger
(collectively, "indemnified liabilities"); and

. all indemnified liabilities based on or arising out of or pertaining to
the amended merger agreement or the offer, the Litton merger or the
Northrop reorganization, to the fullest extent required or permitted
under applicable law or under the governing documents of Litton, as the
surviving corporation of the Litton merger, provided, however, that the
provisions of the governing documents of Litton, as the surviving
corporation of the Litton merger relating to indemnification and
exoneration from liability will be at least as favorable as the
provisions of Litton's governing documents as of the date of the amended
merger agreement.

Furthermore, each of Litton, Northrop Grumman and NNG intend, to the extent
not prohibited by applicable law, that the indemnification described above will
apply to negligent acts or omissions by current and former directors and
officers of Litton or any of its subsidiaries.

The amended merger agreement provides that Litton, as the surviving
corporation in the Litton merger, will maintain for six years after the Litton
merger directors' and officers' liability insurance on terms no less favorable
than Litton's current insurance policy, subject to a limitation on the amount
of the premium required to be paid for the insurance to 300% of the amount paid
as of December 21, 2000.

Employee Matters

Except as otherwise provided in the amended merger agreement, NNG has agreed
to assume and honor in accordance with their terms all Litton employee plans
and all employment agreements disclosed to Northrop Grumman and all accrued
benefits vested thereunder. In addition, for a period of not less than two
years from the effective time of the Litton merger, NNG has agreed to provide
current and former employees of Litton and its subsidiaries ("Litton
employees"), for a period of not less than two years following the effective
time of the Litton merger, with employee benefits in the aggregate no less
favorable than those benefits provided to Litton employees immediately prior to
the effective time of the Litton merger. However, Northrop Grumman is not
prevented from terminating any employment agreement or employee plan in
accordance with its terms or reducing the employment or otherwise changing the
compensation or employee benefits of any individual Litton employee.

Under any new employee benefit plan enacted by NNG, a Litton employee will
be credited with all years of services for which such Litton employee was
credited before the effective time of the Litton merger under similar Litton
employee plans, except to the extent such credit would result in a duplication
of benefits. Each Litton employee will be immediately eligible to participate
in any new employee benefit plans to the extent coverage under the new employee
benefit plan replaces coverage under a comparable Litton employee plan in which
such Litton employee participated immediately prior to the effective time of
the Litton merger. In

addition, NNG will assume and honor Litton's obligations to provide lifetime
benefits under Litton's Supplemental Medical Insurance Plan. Furthermore, NNG
has agreed not to demand repayment of the loans outstanding under Litton's
Incentive Loan Program before December 31, 2001.

On or before January 31, 2001, Litton has agreed to provide Northrop Grumman
with copies of certain documents and information pertaining to employee plans,
employee agreements and arrangements.

The Registration Rights Agreement

The registration rights agreement is filed as an exhibit to the registration
statement, of which this offer to purchase or exchange is a part, and is
incorporated by reference herein. The following summary describes the material
terms of the registration rights agreement. However, the rights of the parties
are governed by its specific terms and conditions and not this summary.

Effective as of January 23, 2001, Northrop Grumman, NNG and Unitrin entered
into the registration rights agreement described below.

Unitrin, its subsidiaries and affiliates and approved transferees may
request that NNG register all or a portion of its shares so long as the
aggregate offering to the public is at least $100,000,000. NNG is required to
file three registration statements in response to a demand for registration by
Unitrin and NNG is not required to file more than one registration statement in
any six month period. NNG may postpone the filing of any registration statement
for up to 75 days if NNG would be required to disclose nonpublic information
and NNG's board of directors determines that disclosure of such nonpublic
information would materially and adversely affect an existing or pending
material business, transaction or negotiation or otherwise materially and
adversely affect Northrop Grumman. NNG may exercise this right to postpone once
in any 12 month period.

If NNG registers any securities for public sale, Unitrin will have the right
to include its shares in this registration. Unitrin's right, however, does not
apply to a registration statement relating to any of NNG's employee benefit
plans or to a corporate reorganization. If marketing reasons dictate, the
managing underwriter of any underwritten offering will have the right to limit
the number of shares registered by Unitrin and its subsidiaries and affiliates
to be included in the registration statement on a pro rata basis to the extent
required.

NNG is not obligated to register securities pursuant to the registration
rights described above if, in the opinion of NNG's counsel, the sale or
disposition of all of Unitrin's registrable securities may be effected without
registering such registrable securities under the Securities Act, except with
respect to a demand registration pursuant to an underwritten public offering.

Either NNG or Northrop Grumman will pay all expenses incurred in connection
with the filings described above. In addition, Unitrin may be required to agree
not to sell its shares of NNG stock during the 7 day period prior to, and
during the 90 day period beginning with, the effectiveness of such registration
statement.

Change of Control Severance Agreements

Litton is party to change of control employment agreements with 53 of its
executives, including all its executive officers. The parties to the amended
merger agreement acknowledged and agreed that the consummation of the offer
will constitute a "change of control" under these agreements. Accordingly, upon
termination of employment by the executive officer for "good reason" or
"without cause" by Litton within three years following the change of control,
or, if the executive officer terminates employment for any reason during the
30-day period following the first anniversary of the change of control, the
executive officer will be entitled to three times the executive officer's base
salary and highest bonus award of any type, including, without limitation, any
annual or signing bonus paid during the last three full fiscal years,
continuation of welfare benefits for three years, three years of service credit
under Litton's pension plan and, if applicable, the Supplemental Executive
Retirement Plan, and provision of certain other benefits in accordance with
Litton's plans and practices. On December 21, 2000, the compensation and
selection committee of the Litton board of directors specified that the
following comprise these other benefits:

. Incentive Loan Program:

. use of a company automobile by the executive officer without cost, with
a tax gross-up, for three years following termination;

. executive financial planning for an additional year following
termination;

. Directors' and Officers' Liability Insurance for six years following
termination;

. continued participation in the Hyatt Legal Plan for three years
following termination; and

. educational assistance programs for three years following termination.

In addition, the compensation and selection committee of the Litton board of
directors specified that the welfare plan benefits that continue under the
agreements during the three-year period following termination include:

. the supplemental medical insurance plan for key executive employees;

. the executive survivor benefit plan; and

. the executive physical plan.

Under the terms of the change of control employment agreements, Litton will
also pay any legal fees and expenses incurred by the executive officer in
connection with a dispute arising out of the subject matter of the agreement.
If any payment received under an executive officer's change of control
employment agreement or otherwise is subjected to the excise tax imposed under
Section 4999 of the Code, the executive officer is entitled to an additional
payment to restore the executive officer to the same after-tax position that
the executive officer would have been in if the excise tax had not been
imposed.

On December 21, 2000, Dr. Sugar's change of control employment agreement,
dated June 21, 2000, was modified to clarify the intent of both parties that
Dr. Sugar's letter agreement, dated June 21, 2000, was not to be superseded by
his change of control employment agreement.

It is estimated that the total maximum amount of cash severance payable to
each executive officer under these agreements, not including any excise tax
gross-up, would be: $6,188,052 for Mr. Brown, $5,000,000 for Dr. Sugar,
$3,084,869 for Mr. Steuert, $2,997,540 for Mr. St. Pe, $3,366,800 for Mr.
Halamandaris, and $16,128,160 for all remaining executive officers as a group.

Employment Agreement between Northrop Grumman and Dr. Sugar. On December 21,
2000, Northrop Grumman entered into a letter agreement with Dr. Sugar pursuant
to which Dr. Sugar will serve as Corporate Vice President of Northrop Grumman,
President and Chief Executive Officer of Litton, and a member of the board of
directors of Northrop Grumman effective upon the closing date of the Litton
merger, provided that the Litton merger closes on or before December 31, 2001.
On January 31, 2001, Northrop Grumman and Dr. Sugar amended the letter
agreement to provide that Dr. Sugar would be named as an officer and director
of NNG. In general, under the terms of this letter agreement, Northrop Grumman
assumes Litton's obligations under Dr. Sugar's change of control employment
agreement and his letter agreement dated June 21, 2000. However, Dr. Sugar's
rights under those agreements are modified in two respects. First, Dr. Sugar
will not be entitled to severance benefits under those agreements if he
terminates his employment during the employment period commencing on the
closing date of the Litton merger and ending on the later of (i) the date six
months following the closing date or (ii) December 31, 2001, although he will
retain the right to receive severance benefits if he terminates his employment
after that employment period on the basis of an event that occurs during that
employment period that constitutes "good reason" under his change of control
employment agreement or a "constructive termination without cause" prior to
December 31, 2001 under the letter agreement dated June 21, 2000. Second,
during the 30-day period following such employment period, Dr. Sugar will have
the right to voluntarily terminate his employment for any reason and such
termination will be considered a termination for "good reason" under his change
of control employment agreement and a "constructive termination without cause"
prior to December 31, 2001 under the letter agreement dated June 21, 2000. The
letter agreement affirms that in the event of any such termination, Dr. Sugar
will be entitled to a total severance benefit under those agreements equal to
the greater of (i) $5,000,000 or (ii) three times the sum of his annual base
salary and highest bonus award during the last three full fiscal years. In
addition, the letter agreement will not affect Dr. Sugar's right to accelerated
vesting of stock options or restricted stock upon the consummation of the
offer.

Confidentiality Agreement

RATIO OF COMBINED EARNINGS TO FIXED CHARGES AND PREFERRED DIVIDENDS

The following table sets forth the ratios of combined earnings to fixed
charges and preferred dividends of Northrop Grumman for the one year period
ended December 31, 1999 and for the nine-month period ended September 30, 2000
and pro forma combined ratios of Northrop Grumman and Litton for the year ended
December 31, 1999 and nine-month period ended September 30, 2000.

The Pro Forma Ratios of Combined Earnings to Fixed Charges and Preferred
Dividends are based upon the historical financial statements of Northrop
Grumman and Litton adjusted to give effect to the business combination. Two pro
forma transaction scenarios are presented: Minimum Equity Issuance and Maximum
Equity Issuance. The Minimum Equity Issuance scenario is based upon the
assumption that Unitrin, Inc. tenders its shares of Litton common stock for NNG
stock as described in "Other Agreements--The Stockholder's Agreement" beginning
on page 62 of this offer to purchase or exchange and all other shareholders
tender their shares of Litton common stock for cash. The Maximum Equity
Issuance scenario is based upon the assumption that the maximum number of
shares of NNG common stock (i.e. 13,000,000) and the maximum number of shares
of NNG preferred stock (i.e. 3,500,000) are issued, with the remainder of the
purchase price paid in cash. The pro forma amounts have been developed from (a)
the audited consolidated financial statements of Northrop Grumman contained in
Northrop Grumman's Current Report on Form 8-K as filed on August 8, 2000 and
from the unaudited consolidated financial statements of Northrop Grumman
contained in Northrop Grumman's Quarterly Report on Form 10-Q for the period
ended September 30, 2000, which are incorporated by reference in this offer to
purchase or exchange, and (b) the audited consolidated financial statements
contained in Litton's Annual Report on Form 10-K for the fiscal year ended July
31, 2000 and from the unaudited consolidated financial statements as of and for
the quarter ended October 31, 2000 contained in Litton's Current Report on Form
8-K, as filed on January 30, 2001, which are incorporated by reference in this
offer to purchase or exchange. In addition, the audited consolidated financial
statements contained in Litton's Annual Report on Form 10-K for the fiscal year
ended July 31, 1999 and the unaudited consolidated financial statements of
Litton contained in Litton's Quarterly Reports on Form 10-Q for the periods
ended January 31, 1999 and 2000 have been used to bring the financial reporting
periods of Litton to within 31 days of those of Northrop Grumman.

before income taxes and fixed charges, and fixed charges consist of interest
expense, the portion of rental expense calculated to be representative of the
interest factor, and preferred stock dividend. The ratios of earnings to fixed
charges should be read in conjunction with the financial statements and other
financial data included or incorporated by reference in this offer to purchase

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

The Unaudited Pro Forma Condensed Combined Financial Information of Northrop
Grumman and Litton presented below is derived from the historical consolidated
financial statements of each of Northrop Grumman and Litton. The Unaudited Pro
Forma Condensed Combined Financial Information is prepared using the purchase
method of accounting, with Northrop Grumman treated as the acquiror and as if
the transactions had been completed as of the beginning of the periods
presented for statements of operations purposes and on September 30, 2000 for
balance sheet purposes.

For a summary of the proposed business combination, see "The Offer"
beginning on page 23 of this offer to purchase or exchange.

The Unaudited Pro Forma Condensed Combined Financial Information is based
upon the historical financial statements of Northrop Grumman and Litton
adjusted to give effect to the business combination. Two pro forma transaction
scenarios are presented: Minimum Equity Issuance and Maximum Equity Issuance.
The Minimum Equity Issuance scenario is based upon the assumption that Unitrin
tenders its shares for stock as described in "Other Agreements--The
Stockholder's Agreement" beginning on page [ ] of this offer to purchase or
exchange and all other shareholders tender their shares for cash. The Maximum
Equity Issuance scenario is based upon the assumption that the maximum number
of shares of NNG common stock (i.e. 13,000,000) and the maximum number of
shares of NNG preferred stock (i.e. 3,500,000) are issued, with the remainder
of the purchase price paid in cash. The pro forma adjustments for each
transaction scenario are described in the accompanying notes presented on the
following pages. The pro forma statements have been developed from (a) the
audited consolidated financial statements of Northrop Grumman contained in
Northrop Grumman's Current Report on Form 8-K as filed on August 8, 2000 and
from the unaudited consolidated financial statements of Northrop Grumman
contained in Northrop Grumman's Quarterly Report on Form 10-Q for the period
ended September 30, 2000, which are incorporated by reference in this offer to
purchase or exchange, and (b) the audited consolidated financial statements
contained in Litton's Annual Report on Form 10-K for the fiscal year ended July
31, 2000 and from the unaudited consolidated financial statements as of and for
the quarter ended October 31, 2000 contained in Litton's Current Report on Form
8-K, as filed on January 30, 2001, which are incorporated by reference in this
offer to purchase or exchange. In addition, the audited consolidated financial
statements contained in Litton's Annual Report on Form 10-K for the fiscal year
ended July 31, 1999 and the unaudited consolidated financial statements of
Litton contained in Litton's Quarterly Reports on Form 10-Q for the periods
ended January 31, 1999 and 2000 have been used to bring the financial reporting
periods of Litton to within 31 days of those of Northrop Grumman.

The final determination and allocation of the purchase price paid for the
acquisition of Litton may differ from the amounts assumed in this Unaudited Pro
Forma Condensed Combined Financial Information.

Under the purchase method of accounting, the purchase price will be
allocated to the underlying tangible and intangible assets and liabilities
acquired based on their respective fair market values, with the excess recorded
as goodwill. As of the date of this filing, Northrop Grumman has not commenced
the valuation studies necessary to arrive at the required estimates of the fair
market value of the assets and liabilities to be acquired and the related
allocations of purchase price, nor has it identified the adjustments, if any,
necessary to conform Litton data to Northrop Grumman's accounting policies.
Accordingly, Northrop Grumman has used the historical book values of the assets
and liabilities of Litton and has used the historical revenue recognition
policies of Litton to prepare the unaudited pro forma financial statements set
forth herein, with the excess of the purchase price over the historical net
assets of Litton recorded as goodwill and other purchased intangibles. Once
Northrop Grumman has completed the valuation studies necessary to finalize the
required purchase price allocation and have identified any necessary conforming
changes, such pro forma financial statements will be subject to adjustment.
Such adjustments will likely result in changes to the pro forma statement of
financial position to reflect the final allocation of purchase price and the
pro forma statement of income, and there can be no assurance that such
adjustments will not be material.

The Unaudited Pro Forma Condensed Combined Financial Information is provided
for illustrative purposes only and does not purport to represent what the
actual consolidated results of operations or the consolidated financial
position of NNG would have been had the offer and the Litton merger occurred on
the date assumed, nor is it necessarily indicative of future consolidated
results of operations or financial position.

The Unaudited Pro Forma Condensed Combined Financial Information does not
include the realization of cost savings from operating efficiencies, synergies
or other restructurings resulting from the offer and the Litton merger.

The Unaudited Pro Forma Condensed Combined Financial Information should be
read in conjunction with the separate historical consolidated financial
statements and accompanying notes of Northrop Grumman and Litton that are
incorporated by reference in this offer to purchase or exchange.

DESCRIPTION OF NNG CAPITAL STOCK

The terms and conditions of the capital stock of NNG are determined by NNG's
restated certificate of incorporation, which is identical in all material
respects with the certificate of incorporation of Northrop Grumman, and which
is filed as an exhibit to the registration statement, of which this offer to
purchase or exchange a part. The rights preferences and privileges of the NNG
preferred stock are also governed by a certificate of designations, preferences
and rights, which is also filed as an exhibit to the abovementioned
registration statement. The following summary describes the material terms of
these documents. However the legal rights and obligations of stockholders are
governed by the specific language of the restated certificate of incorporation
and certificate of designations, preferences and right, not by this summary.

Authorized Capital Stock

Under NNG's certificate of incorporation, immediately prior to consummation
of the offer, NNG will be authorized to issue (i) 200,000,000 shares of common
stock, par value $1.00 per share, and (ii) 10,000,000 shares of preferred
stock, par value $1.00 per share, of which 3,500,000 will be shares of Series B
Preferred Stock, par value $1.00 per share. As of January 31, 2001, 1,000 of
NNG's common stock and no shares of Series B Preferred Stock were issued and
outstanding. NNG's common stock will be listed on the NYSE under the symbol
"NOC." NNG will seek to list the NNG preferred stock on the NYSE if there are
enough holders to satisfy the minimum listing requirements.

NNG's board of directors is authorized to provide for the issuance by NNG
from time to time of preferred stock in one or more classes or series and, as
to each class or series, to fix the designation or title, the dividend rate, if
any, the voting rights, if any, and the preferences and relative,
participating, optional or other special rights and qualifications, limitations
or restrictions.

Common Stock

Full Payment and Nonassessability

The outstanding shares of NNG's common stock are, and the shares of NNG's
common stock issued pursuant to the offer will be, duly authorized, validly
issued, fully paid and nonassessable when issued and delivered against payment
for the shares.

Voting Rights

Each holder of NNG's common stock is entitled to one vote for each share of
NNG common stock held of record on the applicable record date on all matters
submitted to a vote of stockholders. The NNG common stock does not have
cumulative voting rights.

Dividends

Dividends may be paid on the common stock and on any class or series of
stock entitled to participate with the common stock as to dividends when and as
declared by NNG's board of directors.

Liquidation

If NNG is liquidated, holders of common stock are entitled to receive all
remaining assets available for distribution to stockholders after satisfaction
of NNG's liabilities and the preferential rights of any preferred stock that
may be outstanding at the time. The holders of NNG common stock do not have any
preemptive, conversion or redemption rights.

Rights Plan

For a description of the rights to acquire NNG preferred stock that are
attached to shares of our common stock, see "Comparison of Stockholders'
Rights--Rights Plan" on page 81.

Series B Preferred Stock

Conversion

The conversion rights of the NNG preferred stock are subject to stockholder
approval of the issuance of NNG common stock upon conversion of the NNG
preferred stock. No conversion rights may be exercised until
such stockholder approval is obtained. Northrop Grumman and NNG have agreed to
seek the necessary stockholder approval at the annual meeting of stockholders
in May 2001.

Subject to stockholder approval, each share of NNG preferred stock will be
convertible, at any time, at the option of the holder into the right to receive
shares of NNG common stock, par value $1.00 per share. Initially, each share of
NNG preferred stock will be convertible into the right to receive the number of
shares of NNG common stock equal to the liquidation value of $100.00 per share
divided by 127% of the average closing price of Northrop Grumman common stock
for the five trading days ending two trading days prior to expiration of the
offer.

The conversion ratio is subject to adjustment in the event of certain
dividends and distributions; a reclassification; a merger, consolidation or
sale of substantially all of NNG's assets; liquidation or distribution and
certain other events.

If any adjustment in the number of shares of common stock into which each
share of NNG preferred stock may be converted would result in an increase or
decrease of less than 1% in the number of shares of NNG common stock into which
each share of NNG preferred stock is then convertible, the amount of the
adjustment will be carried forward and the adjustment will be made at the time
of and together with any subsequent adjustment, which, together with any
amounts so carried forward, will aggregate at least 1% of the number of shares
of NNG common stock into which each share of NNG preferred stock is then
convertible.

Liquidation

In any liquidation of NNG, each share of the NNG preferred stock will be
entitled to a liquidation preference of $100.00 plus accrued but unpaid
dividends, whether or not declared, before any distribution may be made on the
NNG common stock or any other class or series of NNG stock which is junior to
the NNG preferred stock. In any liquidation of NNG, no distribution may be made
on any NNG stock ranking on a parity with the NNG preferred stock as to
dividends, redemption payments and rights upon liquidation dissolution or
winding up of NNG, unless the holders of NNG preferred stock participate
ratably in the distribution along with the holders of any NNG stock ranking on
a parity with the NNG preferred stock as to such matters. In the event
stockholder approval has not occurred, the amount payable in liquidation will
be the greater of the amount described above and the amount that would be
distributed if such share of NNG preferred stock had been converted into NNG
common stock pursuant to the provision for conversion.

Reacquired Shares

Any shares of NNG preferred stock converted, redeemed, purchased or
otherwise acquired by NNG will be retired and canceled. The reacquired shares
will become authorized but unissued shares of NNG preferred stock, which NNG
may reissue at a later date.

Full Payment and Nonassessability

The shares of NNG's Series B Preferred Stock (referred to as the "NNG
preferred stock") issued pursuant to the offer will be duly authorized, validly
issued, fully paid and nonassessable when issued and delivered against payment
for the shares.

Rank

The NNG preferred stock ranks with respect to payment of dividends,
redemption payments and rights upon liquidation, dissolution or winding up,
prior to the NNG common stock and any class or series of preferred stock which
by its terms ranks junior to the NNG preferred. The NNG preferred stock ranks
on parity with each other class or series of preferred stock.

Voting Rights

Holders of NNG preferred stock have no voting rights except in certain
specified circumstances described below or as required by applicable law. The
affirmative vote of the holders of two-thirds of the aggregate number of
outstanding shares of the NNG preferred stock is required for an amendment of
the NNG restated certificate of incorporation, merger or other action which
would:

. authorize any class or series of stock ranking prior to the NNG preferred
stock as to dividends, redemption payments or rights upon liquidation,
dissolution or winding up;

. adversely alter the preferences, special rights or powers given to the
NNG preferred stock; or

. cause or permit the purchase or redemption of less than all of the NNG
preferred stock unless all dividends to which such shares are entitled
have been declared and paid or provided for.

If accrued dividends on the NNG preferred stock are not paid for six
quarterly dividend periods (whether or not consecutive), a majority of the
holders of the NNG preferred stock, voting separately as a class, will have the
right to elect two directors. If such holders exercise their right to elect two
directors to NNG's board, the size of NNG's board will be increased by two
members until the dividends in default are paid in full or payment is set
aside.

Dividends

Holders of NNG preferred stock will be entitled to cumulative cash
dividends, payable quarterly in April, July, October and January of each year.
If the NNG preferred stock is issued prior to the 2001 annual meeting of
stockholders of Northrop Grumman (scheduled for May 16, 2001), the initial
dividend rate per share will be $7.00 per year. Commencing after the dividend
payable in October 2001, the dividend rate per share will be $7.00 per year if
stockholder approval for the issuance of NNG common stock upon conversion of
the NNG preferred stock has been obtained or $9.00 per year if it has not been
obtained. The dividend rate per share will be reduced from $9.00 to $7.00 per
year after stockholder approval is obtained. If the NNG preferred stock is
issued after the Northrop Grumman 2001 annual meeting, the initial dividend
rate will be $7.00 per year if stockholder approval for the issuance of the NNG
common stock upon conversion has been obtained and $9.00 per year if
stockholder approval has not been obtained. If the dividend rate per share is
set at $9.00 per year, it will be reduced from $9.00 to $7.00 per year after
stockholder approval is obtained. Dividends are cumulative and payable in cash.

If dividends are payable and have not been paid or set apart in full, the
deficiency must be fully paid or set apart for payment before:

. distributions or dividends are paid on stock ranking junior to the NNG
preferred stock; and

. the redemption, repurchase or other acquisition for consideration of any
NNG stock ranking junior to the NNG preferred stock.

Redemption

. Mandatory Redemption For Cash After Twenty Years. NNG is required to
redeem all of the shares of NNG preferred stock for cash twenty years
and one day from the date of issuance of the NNG preferred stock. The
redemption price per share is equal to the liquidation value of $100.00
per share plus accrued but unpaid dividends, whether or not declared, to
the mandatory redemption date. In the event that Stockholder Approval
has not occurred by the mandatory redemption date, the amount payable
for each share of NNG preferred stock will be the greater of (a) the
liquidation value of $100.00 per share of NNG preferred stock plus
accrued but unpaid dividends to the redemption date, whether or not
declared, and (b) the current market price on the redemption date of the
number of shares of NNG common stock which would be issued upon
conversion of a share of NNG preferred stock into NNG common stock
pursuant to the provision for conversion.

. Optional Redemption For Common Stock After Seven Years. NNG has the
option to redeem shares of the NNG preferred stock in exchange for NNG
common stock seven years from the date of the initial issuance of the
NNG preferred. Upon redemption, holders of NNG preferred stock will
receive the number of shares of NNG common stock equal to the
liquidation value of $100.00 per share plus accrued but unpaid dividends
to the redemption date divided by the current market price of the NNG
common stock on the redemption date. In the event that stockholder
approval has not occurred by the redemption date, the number to be
divided in the above calculation will be the greater of the amount
described above and the current market price on the redemption date of
the number of shares of NNG common stock which would be issued if all
shares of NNG preferred stock were converted on the redemption date into
NNG common stock pursuant to the provision for conversion.

Change in Control

Upon a fundamental change in control, as defined below, of NNG, holders of
NNG preferred stock have the right, which may be exercised during the period of
20 business days following notice from NNG, to exchange their shares of NNG
preferred stock for NNG common stock. Each share of NNG preferred stock may be
exchanged in such circumstances for that number of shares of NNG common stock
determined by dividing the liquidation value of $100.00 per share, plus accrued
but unpaid dividends to such date by the current market value of the NNG common
stock on the exchange date. In the event stockholder approval has not been
obtained for the issuance of NNG common stock upon conversion of the NNG
preferred stock, the number to be divided in the above calculation will be the
greater of the amount described above or the current market price of the number
of shares of NNG common stock which would be issued if such share of NNG
preferred stock were converted into NNG common stock pursuant to the provision
for conversion.

A "fundamental change in control" is defined as any merger, consolidation,
sale of all or substantially all of NNG's assets, liquidation or
recapitalization (other than solely a change in the par value of equity
securities) of the NNG common stock in which more than one-third of the
previously outstanding NNG common stock is exchanged for cash, property or
securities other than capital stock of NNG or another corporation.

If the change in control occurred as a result of a transaction (excluding
certain dividends or distributions on, and reclassifications of, NNG common
stock) in which the previously outstanding NNG common stock is changed into or
exchanged for different securities of NNG or securities of another corporation
or interests in a noncorporate entity, the NNG common stock that would
otherwise have been issued to a holder of NNG preferred stock for each share of
NNG preferred stock will be deemed to instead be the kind and amount of
securities and property receivable upon completion of such transaction in
respect of the NNG common stock that would result in the fair market value of
such securities and property, measured as of the exchange date, being equal to
the liquidation value plus accrued and unpaid dividends. In the event that the
Stockholder Approval has not occurred, the fair market value of the securities
and property will instead be calculated to be equal to the greater of the
amount described above, and the fair market value of the securities and
property which would have been issued if such share of NNG preferred stock had
been converted into NNG common stock, if conversion were permitted.

Transfer and Dividend Paying Agent and Registrar

First Chicago Trust Company is the transfer and dividend paying agent and
registrar for the NNG common stock.

COMPARISON OF STOCKHOLDERS' RIGHTS

Upon completion of the offer, stockholders of Litton who request NGC stock
will become stockholders of NNG. As an NNG stockholder, the rights of former
Litton stockholders will be governed by NNG's restated certificate of
incorporation and NNG's bylaws, which differ in certain material respects from
Litton's restated certificate of incorporation and Litton's bylaws. Set forth
on the following pages is a summary comparison of certain material differences
between the rights of NNG's stockholders under the NNG restated certificate of
incorporation and the NNG bylaws and the rights of a Litton stockholder under
the current Litton restated certificate of incorporation and the current Litton
bylaws. Delaware is the jurisdiction of incorporation for both NNG and Litton.
Therefore, the rights of former Litton stockholders who become NNG stockholders
will continue to be governed by the DGCL.

The restated certificate of incorporation and bylaws of NNG are filed as
exhibits to the registration statement of which this offer to purchase or
exchange is a part. The specific provisions of such documents, and not this
summary, determine the rights and obligations of the parties.

Amendments to Certificate of Incorporation

The affirmative vote of a majority of the outstanding shares entitled to
vote is required to amend NNG's restated certificate of incorporation. In
addition, amendments which make changes relating to the capital stock by
increasing or decreasing the par value or the aggregate number of authorized
shares of a class or otherwise adversely affect the rights of such class, must
be approved by the majority vote of each class of stock affected, unless, in
the case of an increase in the number of shares, the charter takes away such
right, and provided that, if the amendment affects some but not all series,
then only those affected series will have a vote. NNG's restated certificate of
incorporation provides that certain articles may only be adopted, repealed,
rescinded, altered or amended by the affirmative vote of the holders of at
least 80% of the voting power of all outstanding shares of voting stock
regardless of class and voting together as a single voting class. However, if
such action is proposed by an interested stockholder, as defined in NNG's
restated certificate of incorporation, or by an associate or affiliate of an
interested stockholder, the affirmative vote of a majority of the voting power
of all of the outstanding shares of voting stock other than shares held by such
interested person is required, voting together as a single class; provided,
however, that where such action is approved by a majority of the continuing
directors, the affirmative vote of a majority of the voting power of all
outstanding shares of voting stock, regardless of class and voting together as
a single class shall be required for approval of such action. In general, NNG's
charter defines an "interested stockholder" as a beneficial owner of 10% or
more of the voting power of all outstanding shares of voting stock.

Under the DGCL, the affirmative vote of a majority of the outstanding shares
entitled to vote is required to amend Litton's restated certificate of
incorporation. In addition, the affirmative vote of the holders of at least
two-thirds of the aggregate number of shares of the affected class or series of
preferred stock outstanding are entitled to vote on any amendment of Litton's
restated certificate of incorporation that would:

. create a new class of stock having rights or preferences with respect to
payment of dividends or distribution of assets that are prior to the
shares of such class of preferred stock;

. alter or change the preferences, special rights or powers given to any
class or series of preferred stock so as to adversely affect such class
of stock; or

. effect a purchase or redemption of less than all of the shares of
preferred stock then outstanding unless the full dividends to which all
shares of the preferred stock of all series then outstanding shall then
be entitled shall have been paid or declared and a sum set aside
sufficient for the payment thereof.

Amendments to the NNG Bylaws and the Litton Restated Bylaws

Under the NNG restated certificate of incorporation and the NNG bylaws, the
NNG bylaws may be adopted, repealed, rescinded, altered or amended by NNG
stockholders, but only by the affirmative vote of the holders of at least 80%
of the voting power of all outstanding shares of voting stock, regardless of
class and voting together as a single class. However, if an interested
stockholder or any associate or affiliate of an interested stockholder proposes
amending the NNG bylaws, then, approval by the holders of a majority of the
voting power of all outstanding shares or voting stock other than the shares
held by such interested stockholder is required, regardless of class and voting
together as a single class; provided, however, that where such action is
approved by a majority of the continuing directors, the affirmative vote of a
majority of the voting power of all outstanding shares of voting stock,
regardless of class and voting together as a single class shall be required for
approval of such action.

The Litton restated certificate of incorporation provides that the Litton
board of directors may make, alter, amend, change, add to, or repeal the Litton
restated bylaws. The Litton restated bylaws provide that they may be altered or
repealed and new bylaws may be adopted either:

. at any annual or special meeting of stockholders by the affirmative vote
of a majority of the issued and outstanding voting stock, if notice of
the proposed alteration, repeal or adoption of the new provision(s) is
contained in the notice of such special meeting; or

. by the affirmative vote of a majority of the directors present at any
regular meeting, or at any special meeting of the Litton board of
directors, if notice of the proposed alteration, repeal or new
provision(s) is contained in the notice of such special meeting.

Vote Required for Merger and Other Business Combinations

Under the DGCL, generally, the approval of a majority of the outstanding
shares is needed to adopt a plan of merger or consolidation. Section 203 of the
DGCL prohibits a Delaware corporation which has a class of stock which is
listed on a national securities exchange or which has 2,000 or more
stockholders of record from engaging in a business combination with an
interested stockholder (generally, the beneficial owner of 15% or more of the
corporation's outstanding voting stock) for three years following the time the
stockholder became an interested stockholder, unless, prior to that time, the
corporation's board of directors approved either the business combination or
the transaction that resulted in the stockholder becoming an interested
stockholder, or if two-thirds of the outstanding shares not owned by such
interested stockholder approve the business combination, or if, upon becoming
an interested stockholder, such stockholder owned 85% of the outstanding shares
excluding those held by officers, directors and some employee stock plans.

In addition to the DGCL requirements, NNG's restated certificate of
incorporation provides that, subject to some exceptions, any business
combination between NNG or any NNG subsidiary and an interested stockholder
must be approved by at least 80% of the voting power of all outstanding voting
stock, regardless of class and voting together as a single class and a majority
of the voting power of all outstanding shares of voting stock, other than the
shares held by any interested stockholder which is a party to such business
combination or by any affiliate or associate of such interested stockholder,
regardless of class and voting together as a single class.

The Litton restated certificate of incorporation and the Litton bylaws do
not contain any special voting requirements regarding a merger or other
business combination.

Directors

Classification of Board of Directors. A classified board is one with respect
to which a designated number of directors, but not necessarily all, are elected
on a rotating basis each year. Under the DGCL, classification of a board of
directors is permitted but not required, pursuant to which the directors can be
divided into as many as three classes with staggered terms of office, with only
one class of directors standing for election each year. NNG's restated
certificate of incorporation provides that the NNG board of directors be
divided into three classes of directors as nearly equal in number as reasonably
possible, with staggered three-year terms. Each director will serve until his
or her successor is duly elected and qualified or until the director's death,
resignation or removal. See "Removal of Directors" below.

Litton does not have a classified board of directors. Each Litton director
is elected each year at the annual meeting of stockholders. Each director
serves until a successor is duly elected and qualified, or until the director
resigns, or is otherwise removed.

Removal of Directors. NNG's restated certificate of incorporation provides
that NNG directors may be removed only for cause and only by the affirmative
vote of the holders of at least 80% of all outstanding shares of capital stock
of NNG having general voting power entitled to vote in connection with the
election of such director, regardless of class and voting together as a single
voting class; provided, however, that if a proposal to remove a director is
approved by a majority of continuing directors, the affirmative vote of a
majority of all outstanding shares of voting stock entitled to vote in
connection with the election of such director, regardless of class and voting
together as a single voting class, is required for approval of such removal.

Pursuant to Litton's bylaws, Litton directors may be removed, either with or
without cause, at any time by the affirmative vote of the holders of a majority
of all outstanding shares of voting stock entitled to vote at a special meeting
of the stockholders called for that purpose.

Newly Created Directorships and Vacancies. Under NNG's restated certificate
of incorporation and NNG's bylaws, newly created directorships resulting from
death, resignation, disqualification, an increase effected by NNG's board of
directors, or any other cause, may be filled solely by the affirmative vote of
a majority of the directors then in office, although less than a quorum, or by
a sole remaining director. Each director so chosen to fill a vacancy will hold
office for the remainder of the full term of the class of directors in which
the vacancy occurred and until such director's successor shall have been
elected and qualified. No reduction of the authorized number of directors will
have the effect of removing any director prior to the expiration of his or her
term of office.

Under the Litton restated bylaws, vacancies in the Litton board of directors
may be filled by the affirmative vote of a majority of the directors then in
office. Each director so chosen to fill a vacancy will hold office for the
remainder of the term and until a successor is duly chosen. However, Litton's
charter provides that the holders of preferred stock, voting separately as
class, will be entitled to elect two directors, if and whenever accrued
dividends on any series of preferred stock of Litton have not been paid or
declared and a sum sufficient for the payment thereof set aside, in an amount
equivalent to six quarterly dividends or three semiannual dividends on all
shares of such series of preferred stock at the time outstanding.

Size of Board. NNG's bylaws provide that the number of directors will be
fixed by resolution of the board of directors, but will not be less than three.

The Litton restated bylaws provide that the number of directors shall be
fixed from time to time by resolution of the board of directors but shall not
be less than eight nor more than fourteen.

Quorum of the Board. NNG's bylaws provide for a quorum of a majority of the
board of directors, except that when the board of directors consists of one
director, then that one director will constitute a quorum.

Litton's restated bylaws provide for a quorum of a majority of the board of
directors. No more than a minority of the number of directors necessary to
constitute a quorum of the board of directors can be non U.S. citizens.

Stockholders

Annual Meetings. NNG's bylaws provide that the annual meeting of
stockholders will be held between May 1 and July 1 of each year on a date and
time fixed by the board of directors.

Litton's restated bylaws provide that the annual meeting of stockholders,
and all other meetings of the stockholders, will be held on a date fixed by
resolution of the board of directors.

Special Meetings. Under NNG's restated certificate of incorporation and
NNG's bylaws, special stockholder meetings may be called at any time by a
majority of the board of directors, the Chairman of the board of directors or
by the President and Chief Executive Officer.

Under Litton's restated bylaws, special stockholder meetings may be called
by resolution of the Litton board of directors or the Litton executive
committee or at any time by the written request of stockholders of record
owning at least 51% of the issued and outstanding voting shares of Litton
common stock.

Quorum Requirements. Under both the NNG bylaws and the Litton restated
bylaws, the presence in person or by proxy of the holders of record of a
majority of the shares issued and outstanding and entitled to vote at the
meeting constitutes a quorum for that meeting, except as otherwise provided by
the DGCL.

Certain Voting Requirements. Under the NNG bylaws, except as otherwise
provided by NNG's charter or by applicable law, action by NNG stockholders
generally is taken by the affirmative vote, at a meeting at which a quorum is
present, of a majority of the outstanding shares entitled to vote thereon,
including extraordinary actions, such as mergers, consolidations and amendments
to NNG's charter. However, NNG's restated certificate of incorporation requires
the affirmative vote of at least 80% of the outstanding shares of voting stock
to approve an amendment of specified articles in the restated certificate of
incorporation. The restated certificate of incorporation also requires the
affirmative vote of (i) at least 80% of all outstanding shares entitled to vote
and (ii) a majority of all outstanding shares other than shares held by an
interested stockholder and its affiliates for the approval of:

. certain business combinations (as defined in the restated certificate of
incorporation) and other significant transactions involving the
interested stockholder or its affiliate, and

. the amendment of specified provisions of the restated certificate of
incorporation if proposed by the interested stockholder.

Litton does not have any special voting provisions beyond those described
above for holders of Litton preferred stock. See "Description of NNG Capital
Stock--Series B Preferred Stock--Voting Rights" beginning on page 75.

Stockholder Action by Written Consent. Under NNG's restated certificate of
incorporation and NNG's bylaws, any action required or permitted to be taken by
stockholders must be effected at a duly called annual meeting or at a special
meeting of stockholders, unless such action requiring or permitting stockholder
approval is approved by a majority of the continuing directors, in which case
such action may be authorized or taken by the written consent of the holders of
outstanding shares of voting stock having at least the minimum voting power
that would be necessary to authorize or take such action at a meeting of
stockholders at which all shares entitled to vote thereon were present and
voted, provided all other requirements of applicable law and the NNG restated
certificate of incorporation have been satisfied.

Under Litton's restated certificate of incorporation and Litton's restated
bylaws, stockholder actions may not be taken by written consent, in lieu of a
meeting.

Stockholder Proposal Procedures. Under NNG's bylaws, for a matter to be
properly brought before an annual meeting by a stockholder, the stockholder
generally must have given timely notice thereof in writing to NNG's Secretary
not less than 45 days nor more than 75 days prior to the anniversary date of
the immediately preceding annual meeting. A stockholder's notice must state as
to each matter the stockholder proposes to bring before the annual meeting: (a)
a brief description of the matter desired to be brought, the reasons for
conducting such business at the meeting, any material interest in such business
of the stockholder and the beneficial owner, if any, on whose behalf the
proposal is made, or (b) if the stockholder is nominating an individual as a
director (i) information regarding the person whom the stockholder proposes to
nominate as a director; (ii) the name and address of the stockholder proposing
such action; (iii) the class and number of shares of NNG which are beneficially
owned by the stockholder; and (iv) whether the stockholder intends to deliver a
proxy statement and form of proxy to a sufficient number of holders of NNG's
voting shares to elect such nominee.

Under Litton's restated bylaws, for a matter to be properly brought before
an annual meeting by a stockholder, the stockholder generally must have given
timely notice thereof in writing to Litton's Secretary not less than 90 days
nor more than 120 days prior to the anniversary date of the immediately
preceding annual meeting. Litton stockholders are subject to the same
stockholder notice requirements set forth above for NNG stockholders except
that a Litton stockholder is not subject to the requirement of disclosing his
or her intention to deliver a proxy statement and form of proxy.

Rights Plan

NNG has adopted a rights plan pursuant to which a preferred share purchase
right is attached to each share of NNG common stock that is or becomes
outstanding prior to October 31, 2008. The NNG rights become exercisable 10
days after the public announcement that any person or group has (i) acquired
15% or more of the outstanding shares of NNG common stock, or (ii) initiated a
tender offer for shares of NNG common stock, which, if consummated, would
result in any person or group acquiring 15% or more of the outstanding shares
of NNG common stock. Once exercisable, each NNG right will entitle the holder
to purchase one one-thousandth of a share of NNG Series A junior participating
preferred stock, par value $1.00 per share, at a price of $250.00 per one one-
thousandth of a share, subject to adjustment. Alternatively, under certain
circumstances involving an acquisition of 15% or more of the NNG common stock
outstanding, each NNG right will entitle its holder to purchase, at a fifty
percent discount, a number of shares of NNG common stock having a market value
of two times the exercise price of the NNG right. NNG may (i) exchange the NNG
rights at an exchange ratio of one share of NNG common stock per NNG right, and
(ii) redeem the NNG rights, at a price of $0.01 per NNG right, at any time
prior to an acquisition of 15% or more of the outstanding shares of Litton
common stock by any person or group.

The NNG rights plan will contain provisions to permit the acquisition by
Unitrin of NNG common stock (and NNG common stock issuable upon conversion of
NNG preferred stock) as contemplated by the offer and the stockholder's
agreement. See "Other Agreements--The Stockholder's Agreement" on page 61.

These rights have certain anti-takeover effects and cause substantial
dilution to a person or group that attempts to acquire control of the
corporation on terms not approved by the corporation's board of directors.

Litton has adopted a rights plan pursuant to which a preferred share
purchase right is attached to each share of Litton common stock that is or
becomes outstanding prior to August 17, 2004. The terms upon which the Litton
rights become exercisable are identical to those for the NNG rights. Once
exercisable, each Litton right will entitle the holder to purchase one one-
thousandth of a share of Litton Series A participating preferred stock, par
value $5.00 per share, at a price of $150.00 per one one-thousandth of a share,
subject to adjustment. Under certain circumstances involving an acquisition of
15% or more of the Litton common stock outstanding, each Litton right will
entitle its holder to purchase, at a 50% discount, a number of shares of Litton
common stock having a market value of two times the exercise price of the
Litton right. Litton may (i) exchange the Litton rights at an exchange ratio of
one share of Litton common stock per Litton right, and (ii) redeem the
Litton rights, at a price of $0.01 per Litton right, at any time prior to an
acquisition of 15% or more of the

outstanding shares of Litton common stock by any person or group. Litton's
board of directors has amended the Litton rights plan so that none of Northrop
Grumman, NNG or LII Acquisition will be deemed an acquiring person.

SUMMARY OF CERTAIN STATUTORY PROVISIONS

Appraisal Rights

No appraisal rights are available in connection with the offer.

If NNG acquires at least 90% of the shares of Litton common stock and at
least 90% of the shares of Litton preferred stock pursuant to the offer, the
Litton merger may be consummated without a meeting or vote of the Litton
stockholders.

If less than 90% of the shares of Litton preferred stock are acquired
pursuant to the offer and a stockholder vote is required to approve the Litton
merger, holders of Litton preferred stock may have appraisal rights in
connection with the Litton merger under certain circumstances. If the Litton
preferred stock is not listed on a national securities exchange or quoted on
the NASDAQ National Market System on the record date fixed to determine the
stockholders entitled to receive notice of and to vote on the Litton merger,
the Litton preferred stock will have appraisal rights pursuant to Section 262
of the DGCL ("Section 262").

In addition, holders of Litton common stock at the effective time of the
Litton merger who do not wish to accept the same amount of cash consideration
in the Litton merger as was paid to holders of Litton common stock in the offer
will have the right to seek an appraisal and to be paid the "fair value" of
their shares of Litton common stock at the effective time of the Litton merger
(exclusive of any element of value arising from the accomplishment or
expectation of the merger) judicially determined and paid to it in cash,
provided that such holder complies with the provisions of such Section 262.

The following is a brief summary of the statutory procedures to be followed
in order to dissent from the Litton merger and perfect appraisal rights under
Delaware law. This summary is not intended to be complete and is qualified in
its entirety by reference to Section 262, the text of which is set forth in
Annex B to this offer to purchase or exchange. Any Litton stockholder
considering demanding appraisal is advised to consult legal counsel.
Dissenters' rights, if any, will not be available unless and until the Litton
merger (or a similar business combination) is consummated.

Litton stockholders of record who desire to exercise their appraisal rights
must fully satisfy all of the following conditions. A written demand for
appraisal of Litton common stock or Litton preferred stock must be delivered to
the Secretary of Litton (x) before the taking of the vote on the approval and
adoption of the amended merger agreement if the Litton merger is not being
effected without a vote of stockholders pursuant to Section 253 of the DGCL (a
"short-form merger"), but rather is being consummated following approval
thereof at a meeting of the Litton stockholders (a "long-form merger") or (y)
within twenty days after the date that Litton, as the corporation surviving the
Litton merger, mails to the Litton stockholders a notice (the "Notice of
Merger") to the effect that the Litton merger is effective and that appraisal
rights are available (and includes in such notice a copy of Section 262 and any
other information required thereby) if the Litton merger is being effected as a
short-form merger without a vote or meeting of the Litton stockholders. If the
Litton merger is effected as a long-form merger, this written demand for
appraisal must be in addition to and separate from any proxy or vote abstaining
from or against the approval and adoption of the amended merger agreement, and
neither voting against, abstaining from voting, nor failing to vote on the
amended merger agreement will constitute a demand for appraisal within the
meaning of Section 262. In the case of a long-form merger, any stockholder
seeking appraisal rights must hold the Litton common stock or Litton preferred
stock for which appraisal is sought on the date the demand is made and,
continuously hold such Litton common stock or Litton preferred stock through
the effective time of the Litton merger, and otherwise comply with the
provisions of Section 262.

In the case of both a short-form merger and a long-form merger, a demand for
appraisal must be executed by or for the stockholder of record, fully and
correctly, as such stockholder's name appears on the stock certificates. If
shares of Litton common stock and Litton preferred stock are owned of record in
a fiduciary capacity, such as by a trustee, guardian or custodian, such demand
must be executed by the fiduciary. If shares of Litton common stock or Litton
preferred stock are owned of record by more than one person, as in a joint
tenancy or tenancy in common, such demand must be executed by all joint owners.
An authorized agent, including an agent for two or more joint owners, may
execute the demand for appraisal for a stockholder of record; provided,
however, the agent must identify the record owner and expressly disclose the
fact that, in exercising the demand, he is acting as agent for the record
owner.

A record owner, such as a broker, who holds Litton common stock or Litton
preferred stock as a nominee for others, may exercise appraisal rights with
respect to the Litton common stock or Litton preferred stock held for all or
less than all beneficial owners of Litton common stock or Litton preferred
stock as to which the holder is the record owner. In such case the written
demand must set forth the number of Litton common stock or Litton preferred
stock covered by such demand. Where the number of shares of Litton common stock
or Litton preferred stock is not expressly stated, the demand will be presumed
to cover all shares of Litton common stock or Litton preferred stock
outstanding in the name of such record owner. Beneficial owners who are not
record owners and who intend to exercise appraisal rights should instruct the
record owner to comply strictly with the statutory requirements with respect to
the exercise of appraisal rights before the date of any meeting of stockholders
of the Company called to approve the Litton merger in the case of a long-form
merger and within twenty days following the mailing of the Notice of Merger in
the case of a short-form merger.

Stockholders who elect to exercise appraisal rights must mail or deliver
their written demands to: Secretary, Litton Industries, Inc., 21240 Burbank
Boulevard, Woodland Hills, California 91367. The written demand for appraisal
should specify the stockholder's name and mailing address, the number of shares
of Litton common stock or Litton preferred stock covered by the demand and that
the stockholder is thereby demanding appraisal of such shares. In the case of a
long-form merger, Litton must, within ten days after the effective time of the
Litton merger, provide notice of the effective time of the Litton merger to all
stockholders who have complied with Section 262 and have not voted for approval
and adoption of the amended merger agreement.

In the case of a long-form merger, stockholders electing to exercise their
appraisal rights under Section 262 must not vote for the approval and adoption
of the amended merger agreement or consent thereto in writing. Voting in favor
of the approval and adoption of the amended merger agreement, or delivering a
proxy in connection with the stockholders meeting called to approve the amended
merger agreement (unless the proxy votes against, or expressly abstains from
the vote on, the approval and adoption of the amended merger agreement), will
constitute a waiver of the stockholder's right of appraisal and will nullify
any written demand for appraisal submitted by the stockholder.

Regardless of whether the Litton merger is effected as a long-form merger or
a short-form merger, within 120 days after the effective time of the Litton
merger, either Litton or any Litton stockholder who has complied with the
required conditions of Section 262 and who is otherwise entitled to appraisal
rights may file a petition in the Delaware Court of Chancery demanding a
determination of the fair value of the shares of the dissenting Litton
stockholders. If a petition for an appraisal is timely filed, after a hearing
on such petition, the Delaware Court of Chancery will determine which
stockholders are entitled to appraisal rights and thereafter will appraise the
Litton common stock and/or Litton preferred stock owned by such Litton
stockholders, determining the fair value of such Litton common stock and/or
Litton preferred stock exclusive of any element of value arising from the
accomplishment or expectation of the Litton merger, together with a fair rate
of interest to be paid, if any, upon the amount determined to be the fair
value. In determining fair value, the Delaware Court of Chancery is to take
into account all relevant factors. In Weinberger v. UOP, Inc., et al., the
Delaware Supreme Court discussed the factors that could be considered in
determining fair value in an appraisal proceeding, stating that "proof of value
by any techniques or methods which are generally considered acceptable in the
financial community and otherwise admissible in court" should be considered and
that "[f]air price obviously

requires consideration of all relevant factors involving the value of a
company." The Delaware Supreme Court stated that in making this determination
of fair value the court must consider "market value, asset value, dividends,
earnings prospects, the nature of the enterprise and any other facts which were
known or which could be ascertained as of the date of merger which throw any
light on future prospects of the merged corporation." The Delaware Supreme
Court has construed Section 262 to mean that "elements of future value,
including the nature of the enterprise, which are known or susceptible of proof
as of the date of the merger and not the product of speculation, may be
considered." However, the court noted that Section 262 provides that fair value
is to be determined "exclusive of any element of value arising from the
accomplishment or expectation of the merger."

Litton stockholders who in the future consider seeking appraisal should have
in mind that the fair value of their Litton common stock or Litton preferred
stock determined under Section 262 could be more than, the same as, or less
than the cash consideration paid for such Litton stock in the offer if they do
seek appraisal of their Litton common stock or Litton preferred stock, and that
opinions of investment banking firms as to fairness from a financial point of
view are not necessarily opinions as to fair value under Section 262. Moreover,
NNG intends to cause Litton, as the corporation surviving the Litton merger, to
argue in any appraisal proceeding that, for purposes thereof, the "fair value"
of the Litton common stock or Litton preferred stock, as the case may be, is
less than that paid in the offer. The cost of the appraisal proceeding may be
determined by the Delaware Court of Chancery and taxed upon the parties as the
Delaware Court of Chancery deems equitable in the circumstances. Upon
application of a dissenting stockholder, the Delaware Court of Chancery may
order that all or a portion of the expenses incurred by any dissenting
stockholder in connection with the appraisal proceeding, including, without
limitation, reasonable attorneys' fees and the fees and expenses of experts, be
charged pro rata against the value of all Litton common stock and/or Litton
preferred stock entitled to appraisal. In the absence of such a determination
or assessment, each party bears its own expenses.

Any Litton stockholder who has duly demanded appraisal in compliance with
Section 262 will not, after the effective time, of the Litton merger, be
entitled to vote for any purpose the Litton common stock and/or Litton
preferred stock subject to such demand or to receive payment of dividends or
other distributions on such Litton common stock or Litton preferred stock,
except for dividends or other distributions payable to stockholders of record
at a date prior to the effective time of the Litton merger.

At any time within 60 days after the effective time of the Litton merger,
any former holder of Litton common stock or Litton preferred stock shall have
the right to withdraw his or her demand for appraisal and to accept the merger
consideration paid for such Litton stock in the offer. After this period, such
holder may withdraw his or her demand for appraisal only with the consent of
Litton, as the corporation surviving the Litton merger. If no petition for
appraisal is filed with the Delaware Court of Chancery within 120 days after
the effective time of the Litton merger, stockholders' rights to appraisal
shall cease and all stockholders shall be entitled to receive the cash
consideration paid for the same class or series of the offer. Inasmuch as
Litton has no obligation to file such a petition, and NNG has no present
intention to cause or permit Litton to do so, any stockholder who desires such
a petition to be filed is advised to file it on a timely basis. However, no
petition timely filed in the Delaware Court of Chancery demanding appraisal
shall be dismissed as to any stockholder without the approval of the Delaware
Court of Chancery, and such approval may be conditioned upon such terms as the
Delaware Court of Chancery deems just.

Failure to take any required step in connection with the exercise of
appraisal rights may result in the termination or waiver of such rights.

Appraisal rights cannot be exercised at this time. The information set forth
above is for informational purposes only with respect to alternatives available
to stockholders if the Litton merger is consummated. Stockholders who will be
entitled to appraisal rights in connection with the Litton merger will receive
additional information concerning appraisal rights and the procedures to be
followed in connection therewith before such stockholders have to take any
action relating thereto.

Litton stockholders who sell or exchange Litton common stock or sell Litton
preferred stock in the offer will not be entitled to exercise appraisal rights
in connection with the offer but, rather, will receive the cash consideration
paid in the offer for such shares.

The foregoing summary of the rights of objecting stockholders under the DGCL
does not purport to be a complete statement of the procedures to be followed by
Litton stockholders desiring to exercise any available dissenters' rights. The
foregoing summary is qualified in its entirety by reference to Section 262. The
preservation and exercise of dissenters' rights require strict adherence to the
applicable provisions of the DGCL. See Annex B attached to this offer to
purchase or exchange.

Certain Business Combinations

Delaware law restricts the ability of certain persons to acquire control of
a Delaware corporation.

Section 203 of the DGCL limits specified business combinations of Delaware
corporations with interested stockholders. Under the DGCL, if a person acquires
beneficial ownership of 15% or more of the stock of a Delaware corporation,
thereby becoming an interested stockholder, that person generally may not
engage in specified transactions with the corporation for a period of three
years following the time that such stockholder became an interested stockholder
unless:

. the corporation's board of directors approved the acquisition of stock
or the transaction prior to the time that the person became an
interested stockholder;

. upon consummation of the transaction in which the person became an
interested stockholder, the interested stockholder owned at least 85% of
the voting stock of the corporation outstanding at the time the
transaction commenced, excluding voting stock owned by directors who are
also officers and certain employee stock ownership plans; or

. at or subsequent to such time, the transaction is approved by the board
of directors and at an annual or special meeting by the affirmative vote
of 66 2/3% of the outstanding voting stock which is not owned by the
interested stockholder.
Litton has represented to Northrop Grumman, NNG and LII Acquisition in the
amended merger agreement that all actions necessary to ensure that Section 203
of the DGCL does not apply to NNG in connection with the offer, the Litton
merger and the other transactions contemplated by the amended merger agreement
and the stockholder's agreement have been taken.

FORWARD-LOOKING STATEMENTS

Certain of the information included in this offer to purchase or exchange
and in the documents incorporated by reference are forward-looking statements
within the meaning of the securities laws. These include statements and
assumptions with respect to expected future revenues, margins, program
performance, earnings and cash flows, acquisitions of new contracts, the
outcome of competitions for new programs, the outcome of contingencies
including litigation and environmental remediation, the effect of completed
and planned acquisitions and divestitures of businesses or business assets,
the anticipated costs of capital investments, and anticipated industry trends.
Actual results and trends may differ materially from the information,
statements and assumptions as described, and actual results could be
materially less than planned.

Important factors that could cause actual results to differ materially from
those suggested by the forward-looking statements include:

. Northrop Grumman and Litton depend on a limited number of customers. Both
companies' businesses are heavily dependent on government contracts, many
of which are only partially funded. The termination or failure to fund
one or more of these contracts could have a negative impact on
operations. Northrop Grumman and Litton are suppliers, either directly or
as subcontractors or team members, to the U.S. Government and its
agencies as well as foreign governments and agencies. These contracts are
subject to each customer's political and budgetary constraints, changes
in short-range and long-range plans, the timing of contract awards, the
congressional budget authorization and appropriation processes, the
government's ability to terminate contracts for convenience or for
default, as well as other risks such as contractor debarment in the event
of certain violations of legal and regulatory requirements.

. Many of the companies' contracts are fixed price contracts. While firm,
fixed price contracts allow the companies to benefit from cost savings,
they also create exposure to the risk of cost overruns. If adjustments to
the estimates used for calculating the contract price are required,
losses may result. In addition, some contracts have provisions relating
to cost controls and audit rights and failure to meet the terms specified
in those contracts can have costly consequences.

. Success or failure in winning new contracts or follow on orders for
existing or future products may cause material fluctuations in future
revenues and operating results. Failure to meet the terms and conditions
specified in those contracts may have adverse consequences.

. Operations are subject to external events which can adversely affect the
ability of Northrop Grumman and Litton to meet contract obligations
within anticipated cost and time parameters. Problems and delays in
delivery may result from issues with respect to design technology,
licensing and patent rights, labor or materials and components that
prevent achievement of contract requirements. Delivery or performance
issues with key suppliers and subcontractors, as well as other factors
may arise. Changes in inventory requirements or other production cost
increases may also have a negative impact on operating results.

. The businesses of Northrop Grumman and Litton are dependent upon the
companies' ability to anticipate changing needs for defense products,
military and civilian electronic systems and support, and information
technology. Failure to design new products which will respond to such
requirements within customers' price limitations would adversely affect
the companies' ability to compete.

. In recent periods, Northrop Grumman has realized significant amounts of
pension income. Future pension income is based upon market performance of
pension assets, which may fluctuate with external economic conditions. As
the result, the portion of earnings attributed to pension income could
vary significantly.

. Results of operations for Northrop Grumman and Litton require management
to make estimates of cost to complete major contracts and other factors
which materially affect reported earnings. Changes in such estimates and
failures to achieve anticipated levels of performance can result in
significant charges against earnings.

See also "Important Considerations Concerning Elections to Receive NNG
Stock" beginning on page 11. Readers are cautioned not to put undue reliance on
forward-looking statements. NNG disclaims any intent or obligation to update
these forward-looking statements, whether as a result of new information,
future events or otherwise.

LEGAL MATTERS

The legality of NNG common stock and preferred stock offered by this offer
to purchase or exchange will be passed upon by John H. Mullan, Corporate Vice
President, Secretary and Associate General Counsel of NNG. Mr. Mullan is paid a
salary by Northrop Grumman, is a participant in various employee benefit plans

EXPERTS

The consolidated financial statements as of December 31, 1999 and 1998 and
for each of the three years in the period ended December 31, 1999 and the
related financial statement schedule incorporated in this offer to purchase or
exchange by reference from Northrop Grumman Corporation's Current Report on
Form 8-K dated August 8, 2000 have been audited by Deloitte & Touche LLP,
independent auditors, as stated in their report, which is incorporated herein
by reference, and have been so incorporated in reliance upon the report of such
firm given upon their authority as experts in accounting and auditing.

With respect to the unaudited interim financial information as of March 31,
2000, June 30, 2000, and September 30, 2000 and for the periods ended March 31,
2000 and 1999, June 30, 2000 and 1999, and September 30, 2000 and 1999 which is
incorporated herein by reference, Deloitte & Touche LLP have applied limited
procedures in accordance with professional standards for a review of such
information. However, as stated in their report included in Northrop Grumman
Corporation's Current Report on Form 8-K dated August 8, 2000 for the quarter
ended March 31, 2000 and Northrop Grumman Corporation's Quarterly Reports on
Form 10-Q for the quarters ended June 30, 2000 and September 30, 2000 and
incorporated by reference herein, they did not audit and they do not express an
opinion on that interim financial information. Accordingly, the degree of
reliance on their reports on such information should be restricted in light of
the limited nature of the review procedures applied. Deloitte & Touche LLP are
not subject to the liability provisions of Section 11 of the Securities Act of
1933 for their report on the unaudited interim financial information because
those reports are not "reports" or a "part" of the registration statement
prepared or certified by an accountant within the meaning of Sections 7 and 11
of the Act.

The consolidated financial statements incorporated in this offer to purchase
or exchange by reference from Litton Industries, Inc.'s Annual Report on Form
10-K for the year ended July 31, 2000 have been audited by Deloitte & Touche
LLP, independent auditors, as stated in their report, which is incorporated
herein by reference, and have been so incorporated in reliance upon the report
of such firm given upon their authority as experts in accounting and auditing.

ANNEX B

Section 262. Appraisal rights

(a) Any stockholder of a corporation of this State who holds shares of stock
on the date of the making of a demand pursuant to subsection (d) of this
section with respect to such shares, who continuously holds such shares through
the effective date of the merger or consolidation, who has otherwise complied
with subsection (d) of this section and who has neither voted in favor of the
merger or consolidation nor consented thereto in writing pursuant to (S) 228 of
this title shall be entitled to an appraisal by the Court of Chancery of the
fair value of the stockholder's shares of stock under the circumstances
described in subsections (b) and (c) of this section. As used in this section,
the word "stockholder" means a holder of record of stock in a stock corporation
and also a member of record of a nonstock corporation; the words "stock" and
"share" mean and include what is ordinarily meant by those words and also
membership or membership interest of a member of a nonstock corporation; and
the words "depository receipt" mean a receipt or other instrument issued by a
depository representing an interest in one or more shares, or fractions
thereof, solely of stock of a corporation, which stock is deposited with the
depository.

(b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to (S) 251 (other than a merger effected pursuant to (S)
251(g) of this title), (S) 252, (S) 254, (S) 257, (S) 258, (S) 263 or (S) 264
of this title:

(1) Provided, however, that no appraisal rights under this section shall
be available for the shares of any class or series of stock, which stock, or
depository receipts in respect thereof, at the record date fixed to determine
the stockholders entitled to receive notice of and to vote at the meeting of
stockholders to act upon the agreement of merger or consolidation, were either
(i) listed on a national securities exchange or designated as a national market
system security on an interdealer quotation system by the National Association
of Securities Dealers, Inc. or (ii) held of record by more than 2,000 holders;
and further provided that no appraisal rights shall be available for any shares
of stock of the constituent corporation surviving a merger if the merger did
not require for its approval the vote of the stockholders of the surviving
corporation as provided in subsection (f) of (S) 251 of this title.

(2) Notwithstanding paragraph (1) of this subsection, appraisal rights
under this section shall be available for the shares of any class or series of
stock of a constituent corporation if the holders thereof are required by the
terms of an agreement of merger or consolidation pursuant to (S)(S) 251, 252,
254, 257, 258, 263 and 264 of this title to accept for such stock anything
except:

a. Shares of stock of the corporation surviving or resulting from
such merger or consolidation, or depository receipts in respect
thereof;

b. Shares of stock of any other corporation, or depository receipts
in respect thereof, which shares of stock (or depository
receipts in respect thereof) or depository receipts at the
effective date of the merger or consolidation will be either
listed on a national securities exchange or designated as a
national market system security on an interdealer quotation
system by the National Association of Securities Dealers, Inc.
or held of record by more than 2,000 holders;
c. Cash in lieu of fractional shares or fractional depository
receipts described in the foregoing subparagraphs paragraphs a.
and b. of this paragraph; or

d. Any combination of the shares of stock, depository receipts and
cash in lieu of fractional shares or fractional depository
receipts described in the foregoing subparagraphs a., b. and c.
of this paragraph.

(3) In the event all of the stock of a subsidiary Delaware corporation
party to a merger effected under (S) 253 of this title is not owned by the
parent corporation immediately prior to the merger, appraisal rights shall be
available for the shares of the subsidiary Delaware corporation.

B-1

(c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets
of the corporation. If the certificate of incorporation contains such a
provision, the procedures of this section, including those set forth in
subsections (d) and (e) of this section, shall apply as nearly as is
practicable.

(d) Appraisal rights shall be perfected as follows:

(1) If a proposed merger or consolidation for which appraisal rights are
provided under this section is to be submitted for approval at a meeting of
stockholders, the corporation, not less than 20 days prior to the meeting,
shall notify each of its stockholders who was such on the record date for such
meeting with respect to shares for which appraisal rights are available
pursuant to subsection (b) or (c) hereof that appraisal rights are available
for any or all of the shares of the constituent corporations, and shall include
in such notice a copy of this section. Each stockholder electing to demand the
appraisal of such stockholder's shares shall deliver to the corporation, before
the taking of the vote on the merger or consolidation, a written demand for
appraisal of such stockholder's shares. Such demand will be sufficient if it
reasonably informs the corporation of the identity of the stockholder and that
the stockholder intends thereby to demand the appraisal of such stockholder's
shares. A proxy or vote against the merger or consolidation shall not
constitute such a demand. A stockholder electing to take such action must do so
by a separate written demand as herein provided. Within 10 days after the
effective date of such merger or consolidation, the surviving or resulting
corporation shall notify each stockholder of each constituent corporation who
has complied with this subsection and has not voted in favor of or consented to
the merger or consolidation of the date that the merger or consolidation has
become effective; or

(2) If the merger or consolidation was approved pursuant to (S) 228 or (S)
253 of this title, each constituent corporation, either before the effective
date of the merger or consolidation or within ten days thereafter, shall notify
each of the holders of any class or series of stock of such constituent
corporation who are entitled to appraisal rights of the approval of the merger
or consolidation and that appraisal rights are available for any or all shares
of such class or series of stock of such constituent corporation, and shall
include in such notice a copy of this section; provided that, if the notice is
given on or after the effective date of the merger or consolidation, such
notice shall be given by the surviving or resulting corporation to all such
holders of any class or series of stock of a constituent corporation that are
entitled to appraisal rights. Such notice may, and, if given on or after the
effective date of the merger or consolidation, shall, also notify such
stockholders of the effective date of the merger or consolidation. Any
stockholder entitled to appraisal rights may, within 20 days after the date of
mailing of such notice, demand in writing from the surviving or resulting
corporation the appraisal of such holder's shares. Such demand will be
sufficient if it reasonably informs the corporation of the identity of the
stockholder and that the stockholder intends thereby to demand the appraisal of
such holder's shares. If such notice did not notify stockholders of the
effective date of the merger or consolidation, either (i) each such constituent
corporation shall send a second notice before the effective date of the merger
or consolidation notifying each of the holders of any class or series of stock
of such constituent corporation that are entitled to appraisal rights of the
effective date of the merger or consolidation or (ii) the surviving or
resulting corporation shall send such a second notice to all such holders on or
within 10 days after such effective date; provided, however, that if such
second notice is sent more than 20 days following the sending of the first
notice, such second notice need only be sent to each stockholder who is
entitled to appraisal rights and who has demanded appraisal of such holder's
shares in accordance with this subsection. An affidavit of the secretary or
assistant secretary or of the transfer agent of the corporation that is
required to give either notice that such notice has been given shall, in the
absence of fraud, be prima facie evidence of the facts stated therein. For
purposes of determining the stockholders entitled to receive either notice,
each constituent corporation may fix, in advance, a record date that shall be
not more than 10 days prior to the date the notice is given, provided, that if
the notice is given on or after the effective date of the merger or
consolidation, the record date shall be such effective date. If no record date
is fixed and the notice is given prior to the effective date, the record date
shall be the close of business on the day next preceding the day on which the
notice is given.

B-2

(e) Within 120 days after the effective date of the merger or consolidation,
the surviving or resulting corporation or any stockholder who has complied with
subsections (a) and (d) hereof and who is otherwise entitled to appraisal
rights, may file a petition in the Court of Chancery demanding a determination
of the value of the stock of all such stockholders. Notwithstanding the
foregoing, at any time within 60 days after the effective date of the merger or
consolidation, any stockholder shall have the right to withdraw such
stockholder's demand for appraisal and to accept the terms offered upon the
merger or consolidation. Within 120 days after the effective date of the merger
or consolidation, any stockholder who has complied with the requirements of
subsections (a) and (d) hereof, upon written request, shall be entitled to
receive from the corporation surviving the merger or resulting from the
consolidation a statement setting forth the aggregate number of shares not
voted in favor of the merger or consolidation and with respect to which demands
for appraisal have been received and the aggregate number of holders of such
shares. Such written statement shall be mailed to the stockholder within 10
days after such stockholder's written request for such a statement is received
by the surviving or resulting corporation or within 10 days after expiration of
the period for delivery of demands for appraisal under subsection (d) hereof,
whichever is later.

(f) Upon the filing of any such petition by a stockholder, service of a copy
thereof shall be made upon the surviving or resulting corporation, which shall
within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the
addresses therein stated. Such notice shall also be given by 1 or more
publications at least 1 week before the day of the hearing, in a newspaper of
general circulation published in the City of Wilmington, Delaware or such
publication as the Court deems advisable. The forms of the notices by mail and
by publication shall be approved by the Court, and the costs thereof shall be
borne by the surviving or resulting corporation.

(g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled
to appraisal rights. The Court may require the stockholders who have demanded
an appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as
to such stockholder.

(h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any
element of value arising from the accomplishment or expectation of the merger
or consolidation, together with a fair rate of interest, if any, to be paid
upon the amount determined to be the fair value. In determining such fair
value, the Court shall take into account all relevant factors. In determining
the fair rate of interest, the Court may consider all relevant factors,
including the rate of interest which the surviving or resulting corporation
would have had to pay to borrow money during the pendency of the proceeding.
Upon application by the surviving or resulting corporation or by any
stockholder entitled to participate in the appraisal proceeding, the Court may,
in its discretion, permit discovery or other pretrial proceedings and may
proceed to trial upon the appraisal prior to the final determination of the
stockholder entitled to an appraisal. Any stockholder whose name appears on the
list filed by the surviving or resulting corporation pursuant to subsection (f)
of this section and who has submitted such stockholder's certificates of stock
to the Register in Chancery, if such is required, may participate fully in all
proceedings until it is finally determined that such stockholder is not
entitled to appraisal rights under this section.

(i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to
the stockholders entitled thereto. Interest may be simple or compound, as the
Court may direct. Payment shall be so made to each such stockholder, in the
case of holders of

B-3

uncertificated stock forthwith, and the case of holders of shares represented
by certificates upon the surrender to the corporation of the certificates
representing such stock. The Court's decree may be enforced as other decrees in
the Court of Chancery may be enforced, whether such surviving or resulting
corporation be a corporation of this State or of any state.

(j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.

(k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded appraisal rights as provided in subsection (d) of
this section shall be entitled to vote such stock for any purpose or to receive
payment of dividends or other distributions on the stock (except dividends or
other distributions payable to stockholders of record at a date which is prior
to the effective date of the merger or consolidation); provided, however, that
if no petition for an appraisal shall be filed within the time provided in
subsection (e) of this section, or if such stockholder shall deliver to the
surviving or resulting corporation a written withdrawal of such stockholder's
demand for an appraisal and an acceptance of the merger or consolidation,
either within 60 days after the effective date of the merger or consolidation
as provided in subsection (e) of this section or thereafter with the written
approval of the corporation, then the right of such stockholder to an appraisal
shall cease. Notwithstanding the foregoing, no appraisal proceeding in the
Court of Chancery shall be dismissed as to any stockholder without the approval
of the Court, and such approval may be conditioned upon such terms as the Court
deems just.

(l) The shares of the surviving or resulting corporation to which the shares
of such objecting stockholders would have been converted had they assented to
the merger or consolidation shall have the status of authorized and unissued
shares of the surviving or resulting corporation.

PART II. INFORMATION NOT REQUIRED IN OFFER TO PURCHASE OR EXCHANGE/PROSPECTUS

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

Section 145 of the DGCL provides that a corporation may indemnify directors
and officers as well as other employees and individuals against expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement in
connection with specified actions, suits or proceedings, whether civil,
criminal, administrative or investigative (other than an action by or in the
right of the corporation--a "derivative action"), if they acted in good faith
and in a manner they reasonably believed to be in or not opposed to the best
interests of the corporation and, with respect to any criminal action or
proceedings, had no reasonable cause to believe their conduct was unlawful.

A similar standard is applicable in the case of derivative actions, except
that indemnification only extends to expenses (including attorneys' fees)
actually and reasonably incurred in connection with the defense or settlement
of such action, and the statute requires court approval before there can be any
indemnification where the person seeking indemnification has been found liable
to the corporation. The statute provides that it is not exclusive of other
indemnification that may be granted by a corporation's charter, bylaws,
disinterested director vote, stockholder vote, agreement or otherwise.

As permitted by Section 145 of the DGCL, Article EIGHTEENTH of NNG's
restated certificate of incorporation, as amended, provides:

"A director of the Corporation shall not be personally liable to the
Corporation or to its stockholders for monetary damages for breach of fiduciary
duty as a director, except for liability (i) for any breach of the director's
duty of loyalty to the Corporation or to its stockholders, (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) under Section 174 of the General Corporation
Law of the State of Delaware, or (iv) for any transaction from which the
director derives any improper personal benefit. If, after approval of this
Article by the stockholders of the Corporation, the General Corporation Law of
the State of Delaware is amended to authorize the further elimination or
limitation of the liability of directors, then the liability of a director of
the Corporation shall be eliminated or limited to the fullest extent permitted
by the General Corporation Law of the State of Delaware, as so amended. Any
repeal or modification of this Article by the stockholders of the Corporation
as provided in Article Seventeen hereof shall not adversely affect any right or
protection of a director of the Corporation existing at the time of such repeal
or modification."

NNG plans to purchase insurance on behalf of any person who is or was a
director, officer, employee or agent of NNG, or is or was serving at the
request of NNG as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise against any
liability asserted against him and incurred by him in any such capacity, or
arising out of his status as such, whether or not NNG would have the power to
indemnify him against such liability under the provisions of NNG's restated
certificate of incorporation, as amended.

ITEM 22. UNDERTAKINGS.

(a) The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made,
a post-effective amendment to this registration statement:

(i) To include any prospectus required by Section 10(a)(3) of the
Securities Act of 1933;

(ii) To reflect in the prospectus any facts or events arising after
the effective date of the registration statement (or the most recent
post-effective amendment thereof) which, individually or in the
aggregate, represent a fundamental change in the information set forth
in the registration statement. Notwithstanding the foregoing, any
increase or decrease in volume of securities offered (if the total
dollar value of securities offered would not exceed that which was
registered) and any deviation from the low or high end of the estimated
maximum offering range may be reflected in the form of prospectus filed
with the Commission pursuant to Rule 424(b) if, in the aggregate, the
changes in volume and price represent no more than a 20 percent change
in the maximum aggregate offering price set forth in the "Calculation
of Registration Fee" table in the effective registration statement;

(iii) To include any material information with respect to the plan
of distribution not previously disclosed in the registration statement
or any material change to such information in the registration
statement;

(2) That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed
to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed
to be the initial bona fide offering thereof; and

(3) To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the
termination of the offering.

(b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act
of 1934) that is incorporated by reference in the registration statement shall
be deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

(c) The undersigned registrant hereby undertakes as follows: that prior to
any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by a person or party
who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes

II-4

that such reoffering prospectus will contain the information called for by the
applicable registration form with respect to reofferings by persons who may be
deemed underwriters, in addition to the information called for by the other
items of the applicable form.

(d) The registrant undertakes that every prospectus: (i) that is filed
pursuant to paragraph (a) immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Act and is used in connection with
an offering of securities subject to Rule 415, will be filed as a part of an
amendment to the registration statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

(e) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the SEC such indemnification is against
public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the registrant of expenses incurred or
paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed
by the final adjudication of such issue.

(f) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11 or 13 of this form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through
the date of responding to the request.

(g) The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

II-5

     NOW, THEREFORE, in consideration of the premises and the representations,
warranties, covenants and agreements herein contained and intending to be
legally bound hereby, the Company, Parent, Holdco and Acquisition I hereby agree
as follows:

                                   ARTICLE 1

                                   THE OFFER

     SECTION 1.1.   The Offer.
                    ---------

     (a)  Provided that this Agreement shall not have been terminated in
accordance with Article 7 and none of the events or conditions set forth in
Annex A shall have occurred and be existing, Parent shall cause Acquisition I
and Holdco to amend the Original Offer not later than February 1, 2001 as
required to reflect the revised terms and conditions set forth in this
Agreement, including Holdco as the Offeror.  In the Offer, each Share together
with the associated Right accepted by Holdco in accordance with the terms of the
Offer shall be exchanged for the right to receive from Holdco, at the election
of the holder of such Share: (X) the Cash Consideration or (Y) the Common Stock
Consideration plus cash in lieu of fractional shares of Holdco Common Stock in
accordance with Section 1.1(g), without interest, or (Z) the Preferred Stock
Consideration plus cash in lieu of fractional shares of Holdco

                                       2


Preferred Stock in accordance with Section 1.1(g), without interest, subject to
proration in the case of alternatives (Y) and (Z) as set forth in Sections
1.1(d) and (e). In the Offer, each Preferred Share accepted by Holdco in
accordance with the terms of the Offer shall be exchanged for the right to
receive the Per Preferred Share Amount. Parent and Holdco shall use all
reasonable efforts to consummate the Offer. Parent shall cause Holdco to accept
for payment, and Holdco shall accept for payment, Shares and Preferred Shares
which have been validly tendered and not withdrawn pursuant to the Offer at the
earliest time following expiration of the offering period in the Offer at which
all conditions to the Offer shall have been satisfied or waived by Holdco. The
obligation of Holdco to accept for payment, and pay for Shares and/or Preferred
Shares tendered pursuant to the Offer shall be subject only to the condition
that the sum of the number of Shares validly tendered plus the number of
Preferred Shares validly tendered shall be at least 25,646,399 shares (the
"Minimum Condition") and the other conditions set forth in Annex A hereto.
Holdco expressly reserves the right to increase the Per Share Amount or the Per
Preferred Share Amount and to waive any condition of the Offer, except the
Minimum Condition. Without the prior written consent of the Company, Holdco
shall not decrease the Per Share Amount or the Per Preferred Share Amount or
change the form of consideration payable in the Offer, decrease the number of
Shares or Preferred Shares sought to be purchased in the Offer, impose
additional conditions to the Offer, amend any other term of the Offer in any
manner adverse to the holders of Shares or Preferred Shares, reduce the time
period during which the Offer shall remain open or waive the Minimum Condition.
The Cash Consideration and the Per Preferred Share Amount shall be paid net to
the seller in cash, less any required withholding of taxes, upon the terms and
subject to the conditions of the Offer. The Company agrees that no Shares or
Preferred Shares held by the Company or any of its subsidiaries will be tendered
in the Offer.

     (b)  Subject to Sections 1.1(d), (e) and (f), each holder of Shares shall
be entitled to elect to specify (i) the number of Shares which such holder
desires to have exchanged for the right to receive the Cash Consideration (a
"Cash Election"), (ii) the number of Shares which such holder desires to have
exchanged for the right to receive Holdco Common Stock (a "Common Stock
Election"); and (iii) the number of Shares which such holder desires to have
exchanged for Holdco Preferred Stock (a "Preferred Stock Election" and together
with a Common Stock Election, the "Stock Elections"). Any Shares which are not
the subject of a valid Common Stock Election or valid Preferred Stock Election
shall be exchanged for the right to receive the Cash Consideration. Any Cash
Election, Common Stock Election or Preferred Stock Election shall be referred to
herein as an "Election." Each holder of Shares making a Preferred Stock Election
shall also specify an Alternative A, Alternative B or Alternative C election,
which election will become effective in the event that proration of the
Preferred Stock Consideration is required as provided in Section 1.1(d). Each
holder of Shares making a Common Stock Election shall also specify an
Alternative A or Alternative B election which election will become effective in
the event that proration of the Common Stock Consideration is required as
provided in Section 1.1(e) and any holder making a Common Stock Election that
does not specify an alternative election shall be deemed to have elected
Alternative B. All Elections shall be made on a form furnished by Parent for
that purpose (a "Form of Election"), which form may be part of the letter of
transmittal accompanying the Offer, and reasonably satisfactory to the Company.
Holders of

                                       3


record of Shares who hold such Shares as nominees, trustees or in other
representative capacities may submit multiple Forms of Election on behalf of
their respective beneficial holders.

     (c)  There shall be no proration of Cash Elections.

     (d)  In the event the total number of Preferred Stock Elections would
require aggregate Preferred Stock Consideration in excess of the Maximum
Preferred Stock Consideration, such Preferred Stock Elections shall be subject
to proration as follows:  For each Preferred Stock Election, the number of
Shares that shall receive the Preferred Stock Consideration shall be the total
number of Shares subject to such Preferred Stock Election multiplied by the
Preferred Stock Proration Factor.  The "Preferred Stock Proration Factor" means
a fraction (x) the numerator of which shall be the Maximum Preferred Stock
Consideration and (y) the denominator of which shall be the product of the
aggregate number of Shares subject to all Preferred Stock Elections made by all
holders of Shares multiplied by the Preferred Stock Consideration.  The maximum
aggregate amount of the Preferred Stock Consideration shall be 3,500,000 shares
of Holdco Preferred Stock (the "Maximum Preferred Stock Consideration").  All
Shares subject to a Preferred Stock Election and an Alternative A or Alternative
B election, other than that number converted into the right to receive the
Preferred Stock Consideration in accordance with this Section 1.1(d), shall be
deemed to be Common Stock Elections (expressing the same Alternative A or
Alternative B election) and converted into the right to receive the Common Stock
Consideration, subject to proration as provided in Section 1.1(e).  All shares
subject to a Preferred Stock Election and an Alternative C election, other than
that number converted into the right to receive the Preferred Stock
Consideration in accordance with this Section 1.1(d), shall be deemed to be Cash
Elections and converted into the right to receive the Cash Consideration.

     (e)  In the event the total number of Common Stock Elections (including any
deemed Common Stock Elections as provided for in Section 1.1(d)) would require
aggregate Common Stock Consideration in excess of the Maximum Common Stock
Consideration, such Common Stock Elections shall be subject to proration as
follows:  (i) First, the Common Stock Elections made by the holders of Shares
making an Alternative A election for proration on their Form of Election for the
Common Stock Election shall be reduced by the lesser of (A) the number of Shares
subject thereto, and (B) the number of Common Stock Elections required to
eliminate such excess treating all Alternative A elections on a pro rata basis
based on the number of Shares subject thereto.  (ii) Second, if the number of
Common Stock Elections is still in excess of the Maximum Common Stock
Consideration, then for each Common Stock Election made by the holder of Shares
making an Alternative B election for proration on their Form of Election for the
Common Stock Election, the number of Shares that shall be converted into the
right to receive the Common Stock Consideration shall be the total number of
Shares subject to such Common Stock Election multiplied by the Common Stock
Proration Factor.  The "Common Stock Proration Factor" means a fraction (x) the
numerator of which shall be the Maximum Common Stock Consideration and (y) the
denominator of which shall be the product of the aggregate number of Shares
subject to all Common Stock Elections which are Alternative B elections
multiplied by the Common Stock Consideration.  (iii) All Shares subject to
Common Stock Elections, after the reduction required by clause (i) above, if
applicable, and subject to proration in accordance with clause (ii) above, if
applicable, shall be converted into the right to receive the

                                       4


Common Stock Consideration. The maximum aggregate amount of the Common Stock
Consideration shall be 13,000,000 shares of Holdco Common Stock (such amount or
any lesser amount specified in accordance with Section 1.1(f) being referred to
as the "Maximum Common Stock Consideration"); provided, however, in no event
                                              --------  -------
shall the Maximum Common Stock Consideration exceed the number of shares of
Holdco Common Stock that Holdco would be permitted to issue without a vote of
Parent or Holdco stockholders pursuant to applicable law or the rules of any
national securities exchange. All Shares subject to an actual or deemed Common
Stock Election, other than that number converted into the right to receive the
Common Stock Consideration in accordance with this Section 1.1(e), shall be
converted into the right to receive the Cash Consideration.

     (f)  In the event that the average of the closing prices for Parent Common
Stock as reported on the New York Stock Exchange Composite Transaction Reporting
System for any five consecutive trading days ending not later than two trading
days prior to the Expiration Date (without giving effect to any extension
resulting from the exercise of the option described in this Section 1.1(f)) is
less than $75.00, Holdco shall have the option, which may be exercised only one
time and must be exercised within two business days after any such five trading
day period, to reduce the Maximum Common Stock Consideration by any number of
shares of Holdco Common Stock.  If Holdco exercises such option: (i) such
exercise shall be irrevocable; (ii) Holdco shall publicly announce within one
business day following such exercise the new Maximum Common Stock Consideration;
and (iii) if such reduction in the Holdco Common Stock in the Offer would,
pursuant to the applicable rules and regulations under the Exchange Act, require
an extension of the Expiration Date, (x) Holdco shall extend the Expiration Date
for the minimum required period and publicly announce within one business day
the new Expiration Date and (y) Holdco agrees to waive, and shall be deemed to
have waived, from and after the Expiration Date prior to the extension thereof
the conditions specified in the initial paragraph of Annex A hereof under
clauses (v)(b), (c), (d) (with respect to a termination by Parent or Acquisition
I pursuant to Section 7.1(d)(i)) and (e)(i).

     (g)  No fractional share of Holdco Common Stock or Holdco Preferred Stock
shall be issued, and each person that would otherwise be entitled to receive a
fractional share shall receive, in lieu thereof, without interest, cash in the
amount of such fraction multiplied by the Average Parent Price (in the case of
Holdco Common Stock) or $100.00 (in the case of Holdco Preferred Stock).

     (h)  Not later than February 1, 2001, Holdco (or Parent on behalf of Holdco
which shall become the successor registrant to Parent under the Securities Act
of 1933, as amended (the "Securities Act") upon consummation of the Northrop
Merger) shall prepare and file with the Securities and Exchange Commission (the
"SEC") a registration statement on Form S-4 to register under the Securities
Act the offer and sale of Holdco Common Stock and the Holdco Preferred Stock
pursuant to the Offer (the "S-4").  The S-4 will include a preliminary
prospectus containing the information required under Rule 14d-4(b) promulgated
under the Securities Exchange Act of 1934, as amended (the "Exchange Act") (the
"Preliminary Prospectus").  Concurrently with the filing of the S-4,
Acquisition I shall file with the SEC an amendment to its previously filed
Tender Offer Statement on Schedule TO with respect to the Original Offer, which
shall include or incorporate by reference all or part of the Preliminary
Prospectus and

                                       5


form of transmittal letter reflecting the Offer and describing the Mergers
(together with any supplements or amendments thereto, collectively the "Offer
Documents"). Promptly thereafter, Parent and Holdco shall cause the Offer
Documents to be disseminated to holders of Shares and Preferred Shares. The
Offer Documents will comply in all material respects with the provisions of
applicable federal securities laws. The information provided and to be provided
by the Company, Parent, Holdco and Acquisition I for use in the S-4 or the Offer
Documents shall not, on the date filed with the SEC and on the date first
published or sent or given to the Company's stockholders, as the case may be,
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading. Parent, Holdco, Acquisition I and the Company each agrees promptly
to correct any information provided by it for use in the S-4 or the Offer
Documents if and to the extent that it shall have become false or misleading in
any material respect and Holdco further agrees to take all steps necessary to
cause the Offer Documents as so corrected to be filed with the SEC and to be
disseminated to holders of Shares and Preferred Shares, in each case as and to
the extent required by applicable federal securities laws.

     (i)  Subject to the terms and conditions thereof, the Offer shall remain
open until at least midnight, New York City time, on the twentieth business day
following the filing of the S-4 and the amendment to the Tender Offer Statement
on Schedule TO (the initial "Expiration Date," and any expiration time and date
established pursuant to an authorized extension of the Offer as so extended,
also an "Expiration Date"); provided, however, that without the consent of the
                            --------  -------
Company Board, Holdco may:  (i) from time to time extend the Offer (each such
individual extension not to exceed five (5) business days after the previously
scheduled Expiration Date), if at the scheduled Expiration Date any of the
conditions of the Offer shall not have been satisfied or waived, until such time
as such conditions are satisfied or waived to the extent permitted by this
Agreement; or (ii) extend the Offer for any period required by any rule,
regulation, interpretation or position of the SEC or the staff thereof
applicable to the Offer.  Parent agrees to cause Holdco to extend the Offer from
time to time in accordance with this Section 1.1(i) for the shortest time
periods which it reasonably believes are necessary until consummation of the
Offer if the conditions of the Offer shall not have been satisfied or waived so
long as this Agreement shall not have been terminated in accordance with Article
7 hereof. Parent and Holdco shall comply with the obligations respecting prompt
payment and announcement under the Exchange Act, and, without limiting the
generality of the foregoing, Holdco shall, and Parent shall cause Holdco to,
accept for payment, and pay for, all Shares and Preferred Shares validly
tendered and not withdrawn pursuant to the Offer promptly following the
acceptance of such Shares and Preferred Shares for payment pursuant to the Offer
and this Agreement.

     SECTION 1.2.   Company Action.
                    --------------

     (a)  The Company hereby approves of and consents to the Offer and
represents and warrants that the Company Board, at a meeting duly called and
held, has, subject to the terms and conditions set forth herein, (i) approved
this Agreement, and deems it and the Offer advisable, and fair to and in the
best interests of the common stockholders of the Company, (ii) approved this
Agreement and the transactions contemplated hereby, including the Stockholder's
Agreements, dated as of the date hereof, among Parent, Holdco, Acquisition I,

                                       6


Unitrin, Inc. (the "Stockholder's Agreement"), the Offer and the Litton Merger,
in all respects and such approval constitutes approval of the Stockholder's
Agreement in the form attached hereto as Exhibit D, the Offer, this Agreement
and the Litton Merger for purposes of Section 203 of the DGCL and (iii) resolved
to recommend that the common stockholders of the Company accept the Offer,
tender their Shares thereunder to Holdco and that the stockholders of the
Company approve and adopt this Agreement and the Litton Merger; provided, that
such recommendation may be withdrawn, modified or amended if permitted by
Sections 5.3 and 5.4. The Company consents to the inclusion of such
recommendation and approval in the Offer Documents. The Company further
represents that Merrill Lynch & Co. (the "Financial Adviser") has delivered to
the Company Board its written opinion that the consideration to be received by
the common stockholders of the Company pursuant to the Offer and the Litton
Merger is fair to such stockholders from a financial point of view.

     (b)  The Company hereby agrees to file with the SEC as soon as practicable
after the filing by Parent and Acquisition I of the amendment to their Offer
Documents pursuant to Section 1.1(h), an amendment to its
Solicitation/Recommendation Statement on Schedule 14D-9 pertaining to the Offer
(together with any amendments or supplements thereto, the "Schedule 14D-9")
containing the recommendation described in Section 1.2(a). The Schedule 14D-9
will comply in all material respects with the provisions of applicable federal
securities laws and, on the date filed with the SEC and on the date first
published, sent or given to the Company's stockholders, shall not contain any
untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary in order to make the statements therein, in
light of the circumstances under which they were made, not misleading, except
that no representation is made by the Company with respect to information
supplied by Parent, Holdco, or Acquisition I in writing for inclusion in the
Schedule 14D-9. The Company, Parent, Holdco, and Acquisition I each agrees
promptly to correct any information provided by it for use in the Schedule 14D-9
if and to the extent that it shall have become false or misleading in any
material respect and the Company further agrees to take all steps necessary to
cause the Schedule 14D-9 as so corrected to be filed with the SEC and
disseminated to the holders of Shares and Preferred Shares, in each case as and
to the extent required by applicable federal securities laws.

     (c)  In connection with the Offer, the Company will promptly furnish
Parent, Holdco, and Acquisition I with mailing labels, security position
listings and any available listing or computer files containing the names and
addresses of the record holders of the Shares and Preferred Shares as of a
recent date and shall furnish Acquisition I with such additional information and
assistance (including, without limitation, updated lists of stockholders,
mailing labels and lists of securities positions) as Acquisition I or its agents
may reasonably request in communicating the Offer to the record and beneficial
holders of Shares and Preferred Shares. Except for such steps as are necessary
to disseminate the Offer Documents and any other documents necessary to
consummate the Mergers, Parent, Acquisition I and their affiliates, associates,
agents and advisors shall use the information contained in any such labels,
listings and files only in connection with the Offer and the Mergers, and, if
this Agreement shall be terminated, will deliver to the Company all copies of
such information then in their possession.

                                       7


     SECTION 1.3.   Board of Directors and Committees; Section 14(f).
                    ------------------------------------------------

     (a)  Promptly upon the purchase by Holdco of Shares pursuant to the Offer
and from time to time thereafter, and subject to the last sentence of this
Section 1.3(a), Holdco shall be entitled to designate up to such number of
directors, rounded to the nearest whole number constituting at least a majority
of the directors, on the Company Board as will give Holdco representation on the
Company Board equal to the product of the number of directors on the Company
Board (giving effect to any increase in the number of directors pursuant to this
Section 1.3) and the percentage that such number of Shares so purchased bears to
the total number of outstanding Shares, and the Company shall use all reasonable
efforts to, upon request by Holdco, promptly, at the Company's election, either
increase the size of the Company Board or secure the resignation of such number
of directors as is necessary to enable Holdco's designees to be elected to the
Company Board and to cause Holdco's designees to be so elected.  At such times,
the Company will use its best efforts to cause persons designated by Holdco to
constitute a majority of each committee of the Company Board, other than any
committee of the Company Board established to take action under this Agreement.
Notwithstanding the foregoing, the Company shall use all reasonable efforts to
ensure that three of the members of the Company Board as of the date hereof
shall remain members of the Company Board until the Effective Time (as defined
in Section 2.2 hereof).  If the number of directors who are members of the
Company Board as of the date hereof is reduced below three prior to the
Effective Time, the remaining directors who are members of the Company Board as
of the date hereof (or if there is only one such director, that remaining
director) shall be entitled to designate a person (or persons) to fill such
vacancy (or vacancies).

     (b)  The Company's obligation to appoint designees to the Company Board
shall be subject to Section 14(f) of the Exchange Act and Rule 14f-1 promulgated
thereunder.  The Company shall promptly take all action required pursuant to
such Section and Rule in order to fulfill its obligations under this Section 1.3
and shall include in the Schedule 14D-9 such information with respect to the
Company and its officers and directors as is required under such Section and
Rule in order to fulfill its obligations under this Section 1.3.  Acquisition I
will supply to the Company in writing and be solely responsible for any
information with respect to itself and its nominees, officers, directors and
affiliates required by such Section and Rule.

obligations or other acts of Parent, Holdco or Acquisition I or waiver of any of
the Company's rights hereunder or other action adversely affecting the rights of
stockholders of the Company (other than Parent, Holdco or Acquisition I), will
require the concurrence of a majority of such directors.

     SECTION 2.8.   Conversion of Shares in the Litton Merger.
                    -----------------------------------------

     (a)  At the Effective Time, each Share held by the Company as treasury
stock, held by any subsidiary of the Company, or owned by Holdco or any of its
subsidiaries, immediately prior to the Effective Time shall be canceled, and no
payment shall be made with respect thereto.  Unless the context otherwise
requires, each reference in this Agreement to the Shares shall include the
associated Rights.

     (b)  At the Effective Time, each share of common stock of Acquisition I
outstanding immediately prior to the Effective Time shall be converted into and
become one share of common stock of the Litton Surviving Corporation with the
same rights, powers and privileges as the shares so converted and shall
constitute the only outstanding shares of capital stock of the Litton Surviving
Corporation (other than as contemplated by Section 2.8(d)).

     (c)  At the Effective Time, except as otherwise provided in Sections 2.8(a)
or 2.11, each Share issued and outstanding immediately prior to the Effective
Time, shall be converted into the right to receive an amount of cash equal to
the Per Share Amount, without interest (the "Merger Consideration").

     (d)  At the Effective Time, each issued and outstanding Preferred Share
(other than any such shares held by Holdco, which shares shall be cancelled at
the Effective Time) shall remain outstanding, without any change, as a share of
the Series B $2 Cumulative Preferred Stock, par value $5.00 per share of the
Litton Surviving Corporation.

     SECTION 2.9.   Payment of Merger Consideration in the Litton Merger.
                    ----------------------------------------------------

     (a)  From time to time following the Effective Time, as necessary to
satisfy the requirements of Section 2.9(b), Parent and Holdco shall deliver to
such agent or agents as may be appointed by Parent and Holdco and reasonably
satisfactory to the Company (the "Payment Agent") for the benefit of the holders
of Shares, in cash the aggregate amount necessary to pay the Merger
Consideration (such cash hereinafter referred to as the "Merger Fund") payable
and issuable pursuant to Section 2.8 in exchange for outstanding Shares.

     (b)  As soon as reasonably practicable after the Effective Time, the
Payment Agent shall mail to each holder of record of a certificate or
certificates which immediately prior to the Effective Time represented
outstanding Shares (the "Certificates") whose shares were converted into the
right to receive the Merger Consideration pursuant to Section 2.8: (i) a letter
of transmittal (which shall specify that delivery shall be effected and risk of
loss and title to the Certificates shall pass only upon delivery of the
Certificates to the Payment Agent and shall be in

                                       11


such form and have such other provisions as Parent and the Company may
reasonably specify) and (ii) instructions for use in effecting the surrender of
the Certificates in exchange for the Merger Consideration. Upon surrender of a
Certificate for cancellation to the Payment Agent together with such letter of
transmittal duly executed, the holder of such Certificate shall be entitled to
receive in exchange therefor a check representing the Merger Consideration which
such holder has the right to receive pursuant to the provisions of this Article
2 and the Certificate so surrendered shall forthwith be canceled. In the event
of a transfer of ownership of Shares which is not registered in the transfer
records of the Company, payment of the Merger Consideration may be made to a
transferee if the Certificate representing such Shares is presented to the
Payment Agent accompanied by all documents required to effect such transfer and
by evidence that any applicable stock transfer taxes have been paid. Until
surrendered as contemplated by this Section 2.9, each Certificate shall be
deemed at any time after the Effective Time to represent only the right to
receive upon such surrender the Merger Consideration as contemplated by this
Section 2.9. Holders of Shares in book-entry form will be entitled to receive
upon delivery to the Paying Agent of a properly completed letter of transmittal,
the Merger Consideration payable for each Share held by such holders in book-
entry form.

     (c)  In the event that any Certificate for Shares shall have been lost,
stolen or destroyed, the Payment Agent shall issue in exchange therefor, upon
the making of an affidavit of that fact by the holder thereof, such Merger
Consideration as may be required pursuant to this Agreement; provided, however,
                                                             --------  -------
that Parent or its Payment Agent may, in its discretion, require the delivery of
a suitable bond or indemnity up to the maximum amount of the Merger
Consideration to be paid.

     (d)  All Merger Consideration paid upon the surrender for exchange of
Shares in accordance with the terms hereof shall be deemed to have been paid in
full satisfaction of all rights pertaining to such Shares; subject, however, to
the Litton Surviving Corporation's obligation to pay any dividends or make any
other distributions with a record date prior to the Effective Time which may
have been declared or made by the Company on such Shares in accordance with the
terms of this Agreement, or prior to the date hereof and which remain unpaid at
the Effective Time, and there shall be no further registration of transfers on
the stock transfer books of the Litton Surviving Corporation of the Shares which
were outstanding immediately prior to the Effective Time. If after the Effective
Time Certificates are presented to the Litton Surviving Corporation for any
reason, they shall be canceled and exchanged as provided in this Article 2.

     (e)  Any portion of the Merger Fund which remains undistributed to the
stockholders of the Company for six months after the Effective Time shall be
delivered to Holdco upon demand and any stockholders of the Company who have not
theretofore complied with this Article 2 shall thereafter look only to Holdco
for payment of their claim for the Merger Consideration.

     (f)  Neither Holdco nor the Company shall be liable to any holder of Shares
for cash from the Merger Fund delivered to a public official pursuant to any
applicable abandoned property, escheat or similar law.

                                       12


     SECTION 2.10.  Stock Options in the Litton Merger.
                    ----------------------------------

     (a)  As of the Effective Time, each outstanding option to purchase Shares
that has been granted by the Company (a "Company Stock Option" or collectively
"Company Stock Options") that is then vested (an "A Option") shall be converted
into the right to receive a cash payment in accordance with the terms of this
Section 2.10(a).  All plans or agreements pursuant to which any Company Stock
Option or Share of restricted stock ("Restricted Stock") or deferred stock unit
has been issued or may be issued are referred to collectively as the "Company
Plans."  Immediately following the Effective Time, Holdco shall pay, or cause
Litton Surviving Corporation to pay, to each holder of an A Option, in
cancellation of such A Option, an amount of cash equal to (x) the excess of (i)
the Cash Consideration over (ii) the per-share exercise price of such Company
Stock Option times (y) the number of Shares subject to such Company Stock
Option, subject to all required tax withholding.

     (b)  As of the Effective Time and subject to Section 2.10(c), Holdco shall
convert each outstanding Company Stock Option that is not an A Option (a "B
Option") into an option to purchase shares of Holdco Common Stock in accordance
with the terms of this Section 2.10(b).  Each B Option shall be deemed to
constitute an option to acquire, on the same terms and conditions as were
applicable under such B Option, a number of shares of Holdco Common Stock (the
"New Share Number") equal to the number of Shares subject to such B Option
times the Common Stock Consideration at a price per share equal to the aggregate
exercise price of such B Option divided by the New Share Number; provided,
                                                                 --------
however, that in the case of any B Option to which Section 421 of the Code
- -------
applies by reason of its qualification under Section 422 of the Code ("incentive
stock options") the option price, the number of shares purchasable pursuant to
such option and the terms and conditions of exercise of such option shall be
determined in order to comply with Section 424(a) of the Code.

     (c)  Holdco's conversion of B Options in accordance with Section 2.10(b)
shall only apply to 1,244,523 unvested options as disclosed by the Company as of
January 12, 2001.  Any B Options in excess of such 1,244,523 options shall be
converted (on a pro rata basis applicable to all B Options) into a right to
receive a cash payment in accordance with Section 2.10(a).

     (d)  Holdco shall have the option to provide the holders of A Options, and
the holders of B Options to the extent applicable B Options are subject to the
conversion set forth in Section 2.10(c), the opportunity to elect, before the
Effective Time, to have some or all of their A Options or B Options, as the case
may be, to be instead converted into options to acquire Holdco Common Stock
pursuant to Section 2.10(b), as if they were B Options; provided, that, if
                                                        --------
Holdco elects to provide optionholders the election provided for herein, A
Options and B Options shall be converted into options to acquire Holdco Common
Stock on a pro rata basis pursuant to this Section 2.10(d) only to the extent
that such conversion would not, separately or together with the other
transactions contemplated by this Agreement, require a vote of Parent or Holdco
stockholders pursuant to applicable law or the rules of any national securities
exchange.

     (e)  It is acknowledged and agreed that each share of Restricted Stock that
is outstanding immediately prior to the consummation of the Offer will vest (and
all restrictions will lapse) upon the consummation of the Offer and all deferred
stock units will become

                                       13


immediately due and payable upon consummation of the Offer. Therefore holders of
such Restricted Stock shall thereupon be entitled to receive the Merger
Consideration in the Merger as set forth in Section 2.9.

     (f)  As soon as practicable after the Effective Time, Holdco shall deliver
to the holders of B Options appropriate notices setting forth such holders'
rights pursuant to the Company Plan and that the agreements evidencing the
grants of such B Options shall continue in effect on the same terms and
conditions (subject to the adjustments required by this Section 2.10 after
giving effect to the Litton Merger).  Holdco shall comply with the terms of the
Company Plans and ensure, to the extent required by and subject to the
provisions of such Plans, that B Options which qualified as incentive stock
options prior to the Effective Time continue to qualify as incentive stock
options of Holdco after the Effective Time.

     (g)  Holdco shall take all corporate action necessary to reserve for
issuance a sufficient number of shares of Holdco Common Stock for delivery upon
exercise of B Options assumed in accordance with Section 2.10(b).  At the
Effective Time, Holdco shall file a registration statement on Form S-8 (or any
successor or other appropriate forms) with respect to the shares of Holdco
Common Stock subject to any options held by persons who are or were directors,
officers or employees of the Company or its subsidiaries and shall use its best
efforts to maintain the effectiveness of such registration statement or
registration statements (and maintain the current status of the prospectus or
prospectuses contained therein) for so long as such options remain outstanding.

     (h)  At or before the Effective Time, the Company shall cause to be
effected any necessary amendments to the Company Plans to give effect to the
foregoing provisions of this Section 2.10.

     SECTION 2.11.  Dissenting Shares in the Litton Merger.  Shares outstanding
                    --------------------------------------
immediately prior to the Effective Time and held by a holder who has neither
voted in favor of the Litton Merger nor consented thereto in writing and who
shall have demanded appraisal for such Shares in accordance with the DGCL
("Dissenting Shares") shall not be converted into a right to receive the Merger
Consideration, unless such holder fails to perfect, withdraws or otherwise loses
its right to appraisal.  If, after the Effective Time, such holder fails to
perfect, withdraws or loses its right to appraisal, such Shares shall be treated
as if they had been converted as of the Effective Time into a right to receive
the Cash Consideration.  The Company shall give Parent prompt notice of any
demands received by the Company for appraisal of Shares.  Except as required by
applicable law or with the prior written consent of Parent, the Company shall
not make any payment with respect to, or settle or offer to settle, any such
demands.

     SECTION 2.12.  Conversion of Shares and Other Matters in the Northrop
                    ------------------------------------------------------
Merger.  All matters pertaining to the conversion of outstanding capital stock,
- ------
and associated rights, of Parent into capital stock and associated rights of
Holdco in the Northrop Merger shall be governed by the terms and provisions of
the Northrop Merger Agreement and Section 251(g) and other applicable provisions
of the DGCL.

                                       14


                                   ARTICLE 3

                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

     Except as publicly disclosed by the Company in the Company SEC Reports and
except as set forth on the Disclosure Schedule (it being agreed that disclosure
of any item in such schedules shall be deemed disclosure with respect to any
section of this Agreement to which the relevance of such item is apparent)
previously delivered by the Company to Parent (the "Company Disclosure
Schedule"), the Company hereby represents and warrants to each of Parent,
Holdco and Acquisition I as follows:

     SECTION 3.1.   Organization and Qualification; Subsidiaries.
                    --------------------------------------------

     (a)  Section 3.1 of the Company Disclosure Schedule identifies each
subsidiary of the Company as of the date of the Original Agreement and its
respective jurisdiction of incorporation or organization, as the case may be.
Each of the Company and its subsidiaries is duly organized, validly existing and
in good standing under the laws of the jurisdiction of its incorporation or
organization and has all requisite corporate power and authority to own, lease
and operate its properties and to carry on its businesses as now being
conducted.  The Company has heretofore delivered to Acquisition I or Parent
accurate and complete copies of the Certificate of Incorporation and Bylaws (or
similar governing documents), as currently in effect, of the Company and its
subsidiaries.

     (b)  Each of the Company and its subsidiaries is duly qualified or licensed
and in good standing to do business in each jurisdiction in which the property
owned, leased or operated by it or the nature of the business conducted by it
makes such qualification or licensing necessary, except in such jurisdictions
where the failure to be so duly qualified or licensed and in good standing would
not have a Company Material Adverse Effect.  The term "Company Material Adverse
Effect" means any changes or effects that, individually or in the aggregate,
are materially adverse to the business, assets, long-term earning capacity or
financial condition of the Company and its subsidiaries, taken as whole, other
than any changes or effects arising out of (i) general economic conditions, (ii)
conditions generally affecting industries in which the Company operates, (iii)
the financial markets or (iv) the entering into or the public announcement or
disclosure of this Agreement or the transactions contemplated hereby.

     SECTION 3.2.   Capitalization of the Company and its Subsidiaries.
                    --------------------------------------------------

     (a)  The authorized capital stock of the Company consists of (i) 120
million Shares, of which, as of November 30, 2000, 45,518,647 Shares were issued
and outstanding, excluding 2,734,083 Shares held in the Company's treasury,

Stockholder Rights Plan dated as of August 17, 1994 (the "Rights Plan") between
the Company and The Bank of New York, as Rights Agent), (ii) 22 million shares
of preferred stock, par value $5.00 per share, of which, as of November 30,
2000, 410,643 Preferred Shares were issued and outstanding and 150,000 shares
were designated as Series A Participating Preferred Stock and were reserved for
issuance under the Rights Plan and (iii) 8 million shares of preference stock,
par value $2.50 per share, no shares of which are

                                       15


outstanding. All of the outstanding Shares have been validly issued and are
fully paid, nonassessable and free of preemptive rights. As of November 30,
2000, 5,194,720 Shares were reserved for issuance pursuant to outstanding
Company Stock Options. Between August 1, 2000 and the date of the Original
Agreement, no shares of the Company's capital stock have been issued other than
pursuant to Company Stock Options already in existence on the date of the
Original Agreement, and between August 1, 2000 and the date of the Original
Agreement no stock options have been granted. Except (i) as set forth above,

the Company, (B) no securities of the Company or its subsidiaries convertible
into or exchangeable for shares of capital stock or voting securities of the
Company, (C) no options or other rights to acquire from the Company or its
subsidiaries and, no obligations of the Company or its subsidiaries to issue any
capital stock, voting securities or securities convertible into or exchangeable
for capital stock or voting securities of the Company and (D) no equity
equivalent interests in the ownership or earnings of the Company or its
subsidiaries (collectively "Company Securities"). As of the date of the
Original Agreement, there are no outstanding obligations of the Company or its
subsidiaries to repurchase redeem or otherwise acquire any Company Securities.
There are no stockholder agreements, voting trusts or other agreements or
understandings to which the Company is a party or by which it is bound relating
to the voting or registration of any shares of capital stock of the Company.

     (b)  All of the outstanding capital stock of the Company's subsidiaries
(other than director's qualifying shares in the case of foreign subsidiaries) is
owned by the Company, or one of its subsidiaries, directly or indirectly, free
and clear of any material Lien or any other material limitation or restriction
(including any restriction on the right to vote or sell the same except as may
be provided as a matter of law) and except for any Liens which are incurred in
the ordinary course of business. There are no securities of the Company or its
subsidiaries convertible into or exchangeable for, no options or other rights to
acquire from the Company or its subsidiaries and no other contract,
understanding, arrangement or obligation (whether or not contingent) providing
for, the issuance or sale, directly or indirectly, by the Company or any of its
subsidiaries of any capital stock or other ownership interests in or any other
securities of any subsidiary of the Company. There are no outstanding
contractual obligations of the Company or its subsidiaries to repurchase, redeem
or otherwise acquire any outstanding shares of capital stock or other ownership
interests in any subsidiary of the Company. For purposes of this Agreement,
"Lien" means, with respect to any asset (including without limitation any
security), any mortgage, lien, pledge, charge, security interest or encumbrance
of any kind in respect of such asset.

     (c)  The Shares and the Preferred Shares constitute the only classes of
equity securities of the Company or its subsidiaries registered or required to
be registered under the Exchange Act.

     (d)  The Company has amended the Rights Plan so that none of Parent, Holdco
or Acquisition I shall be deemed to be an Acquiring Person (as defined in the
Rights Plan) as a result of the execution and delivery of this Agreement or
consummation of the transactions contemplated hereby.

                                       16


     SECTION 3.3. Authority Relative to this Agreement; Recommendation.
                  ----------------------------------------------------

     (a)  The Company has all necessary corporate power and authority to execute
and deliver this Agreement and to consummate the transactions contemplated
hereby. The execution and delivery of this Agreement by the Company and the
consummation by the Company of the transactions contemplated hereby have been
duly and validly authorized by the Company Board and no other corporate
proceedings on the part of the Company are necessary to authorize this Agreement
or to consummate the transactions contemplated hereby except the approval and

Shares and Preferred Shares, voting together as one class. This Agreement has
been duly and validly executed and delivered by the Company and, assuming due

representatives from making such inquiries or conducting such discussions as the
Company Board, after consultation with and based upon the advice of, legal
counsel, may deem necessary to inform itself for the purpose of exercising its
fiduciary duties, and (iii) if the Company receives an unsolicited written
proposal for a Third Party Acquisition from a Third Party that the Company Board
by a majority vote determines in its good faith judgment (after receiving the
advice of a financial adviser of nationally recognized reputation) is reasonably
likely to constitute a Superior Proposal, the Company and its representatives
may conduct such additional discussions or provide such information as the
Company Board shall determine, but only if, prior to such provision of
information or additional discussion (A) such Third Party shall have entered
into a confidentiality and standstill agreement substantially in the

                                       35


form of that certain Confidentiality Agreement entered into between the Company
and Parent dated June 23, 2000 (and containing additional provisions that
expressly permit the Company to comply with the provisions of this Section 5.3)
and (B) the Company Board by a majority vote determines in its good faith
judgment, after consultation with and based upon the advice of, legal counsel
that it is required to do so in order to comply with its fiduciary duties. The
Company shall promptly notify the Parent in the event it receives any proposal
or inquiry concerning a Third Party Acquisition including the terms and
conditions thereof and the identity of the party submitting such proposal; and
the Company shall advise the Parent from time to time of the status and any
material developments concerning the same.

     (b)  Except as set forth in this Section 5.3(b), the Company Board shall
not withdraw, change or modify its recommendation of the transactions
contemplated hereby or approve or recommend, or cause the Company to enter into
any agreement with respect to, any Third Party Acquisition. Notwithstanding the
foregoing, if the Company Board by a majority vote determines in its good faith
judgment, after consultation with and based upon the advice of, legal counsel
that it is required to do so in order to comply with its fiduciary duties, the
Company Board may withdraw its recommendation of the transactions contemplated
hereby or approve or recommend a Superior Proposal, but in each case only (i)
after providing written notice to Parent (a "Notice of Superior Proposal")
advising Parent that the Company Board has received a Superior Proposal,
specifying the material terms and conditions of such Superior Proposal and
identifying the person making such Superior Proposal and (ii) if Parent does
not, within five business days of Parent's receipt of the Notice of Superior
Proposal, make an offer which the Company Board by a majority vote determines in
its good faith judgment (after receiving the advice of a financial adviser of
nationally recognized reputation) to be as favorable to the Company's
stockholders as such Superior Proposal; provided, however, the Company shall not
                                        --------  -------
be entitled to enter into any agreement with respect to a Superior Proposal
(excluding a confidentiality agreement pursuant to Section 5.3(a)) unless and
until this Agreement is terminated by its terms pursuant to Section 7.1 and the
Company has paid all amounts due to Acquisition I pursuant to Section 7.3. For
the purposes of this Agreement, "Third Party Acquisition" means the occurrence
of any of the following events: (i) the acquisition of the Company by merger or
otherwise by any person (which includes a "person" as such term is defined in
Section 13(d)(3) of the Exchange Act) other than Parent, Acquisition I or any
affiliate thereof (a "Third Party"); (ii) the acquisition by a Third Party of
all or a major part of any of the Company's business segments, as identified in
the Company's SEC Reports or more than 20% of the total assets of the Company
and its subsidiaries taken as a whole; (iii) the acquisition by a Third Party of
20% or more of the outstanding Shares; (iv) the adoption by the Company of a
plan of liquidation or the declaration or payment of an extraordinary dividend;
(v) the repurchase by the Company or any of its subsidiaries of more than 20% of
the outstanding Shares; or (vi) the acquisition by the Company or any subsidiary
by merger, purchase of stock or assets, joint venture or otherwise of a direct
or indirect ownership interest or investment in any business whose annual
revenues, net income or assets is equal or greater than 20% of the annual
revenues, net income or assets of the Company. For purposes of this Agreement, a
"Superior Proposal" means any bona fide proposal to acquire directly or
indirectly for consideration consisting of cash and/or securities more than 50%
of the Shares then outstanding or all or substantially all the assets of the
Company and otherwise on terms which the Company Board by a majority vote

                                       36


determines in its good faith judgment (after receiving the advice of a financial
adviser of nationally recognized reputation) to be more favorable, from a
financial point of view, to the Company's stockholders than the Litton Merger.

     SECTION 5.4. Meeting of Stockholders. If a stockholder vote is required for
                  -----------------------
consummation of the Litton Merger, the Company shall take all action necessary
in accordance with the DGCL and its Certificate of Incorporation and Bylaws to
duly call, give notice of, convene and hold a meeting of its stockholders (the
"Stockholders' Meeting") as promptly as practicable after consummation of the
Offer to consider and vote upon the adoption and approval of this Agreement and
the transactions contemplated hereby. The Company shall also as promptly as
practicable after consummation of the Offer, if necessary, prepare and file with
the SEC the Proxy Statement. At the Stockholders' Meeting, Holdco, Acquisition I
and their subsidiaries will vote all Shares and all Preferred Shares owned by
them or as to which they have been granted a proxy in favor of approval and
adoption of this Agreement. The stockholder votes required for the adoption and
approval of the transactions contemplated by this Agreement shall be the vote
required by the DGCL and the Company's Certificate of Incorporation and Bylaws.
The Company will, through its Board of Directors, recommend to its stockholders
approval of such matters as described in Section 1.2(a); provided, however, that
                                                         --------  -------
subject to the provisions of Section 7.3, the Company Board may withdraw, modify
or amend its recommendation if (i) the Company receives a Superior Proposal and
(ii) after complying with the provisions of Section 5.3(b) the Company Board by
a majority vote determines in its good faith judgment after consultation with
and based upon the advice of legal counsel that it is required in order to
comply with its fiduciary duties to recommend the Superior Proposal. The Company
will use all reasonable efforts (i) to obtain and furnish the information
required to be included by it in the Proxy Statement and, after consultation
with Parent and Holder, respond promptly to any comments made by the SEC with
respect to the Proxy Statement and any preliminary version thereof and cause the
Proxy Statement to be mailed to its stockholders at the earliest practicable
time following the expiration or termination of the Offer and (ii) to obtain the
necessary approvals by its stockholders of this Agreement.

     SECTION 5.5. Access to Information.
                  ---------------------

     (a)  Between the date hereof and the Effective Time, the Company will give
Parent and its authorized representatives and Parent will give the Company and
its authorized representatives reasonable access during normal business hours to
all employees, plants, offices, warehouses and other facilities and to all books
and records of itself and its subsidiaries, will permit the other party to make
such inspections as such party may reasonably require and will cause its
officers and those of its subsidiaries to furnish the other party with such
financial and operating data and other information with respect to its business
and properties and those of its subsidiaries as the other party may from time to
time reasonably request.

     (b)  Between the date hereof and the Effective Time, the Company shall
furnish to Parent within 25 business days after the end of each fiscal quarter
(commencing with the first fiscal quarter ending after the date hereof) an
unaudited balance sheet of the Company as of the end of such fiscal quarter and
the related statements of earnings, stockholders' equity (deficit)

                                       37


and cash flows for the quarter then ended, each prepared in conformity with the
accounting practices consistently applied by the Company with respect to its
quarterly financial statements.

     (c)  Notwithstanding the foregoing, the Company shall not be required to
provide any information which it reasonably believes it may not provide by
reason of any applicable law, rules or regulations, which constitutes
information protected by attorney/client privilege, or which it or any of its
subsidiaries is required to keep confidential by reason of contract, agreement
or understanding with third parties.

     (d)  Each of the parties hereto will hold and will cause its consultants
and advisers to hold in confidence all documents and information furnished to it
in connection with the transactions contemplated by this Agreement pursuant to
the terms of that certain Confidentiality Agreement entered into between the
Company and Parent dated June 23, 2000 and each of the parties shall comply with
all agreements, covenants, and restrictions contained therein.

     SECTION 5.6. Additional Agreements; Reasonable Efforts.
                  -----------------------------------------

     (a)  Subject to the terms and conditions herein, Company, Parent, Holdco
and Acquisition I each agrees to use all reasonable efforts to take, or cause to
be taken, all reasonable actions necessary, proper or advisable to consummate
and make effective as promptly as practicable the transactions contemplated by
this Agreement (including, without limitation, the Mergers) and to reasonably
cooperate with the others in connection with the foregoing, including using all
reasonable efforts (i) to obtain all necessary waivers, consents and approvals
from other parties to material loan agreements, leases and other contracts, (ii)
to obtain all consents, approvals and authorizations that are required to be
obtained under any federal, state, local or foreign law or regulation, (iii) to
lift or rescind any injunction or restraining order or other order adversely
affecting the ability of the parties hereto to consummate the transactions
contemplated hereby (including, without limitation, the Mergers), (iv) to effect
all necessary registrations and filings including, but not limited to, filings
and submissions of information requested or required by any domestic or foreign
government or governmental or multinational authority, including, without
limitation, the Antitrust Division of the United States Department of Justice,
the Federal Trade Commission, any State Attorney General, or the European
Commission ("Governmental Antitrust Authority"), and (v) to fulfill all
conditions to this Agreement.  Company, Parent, Holdco and Acquisition I further
covenant and agree, with respect to a threatened or pending preliminary or
permanent injunction or other order, decree or ruling or statute, rule,
regulation or executive order that would adversely affect the ability of the
parties hereto to consummate the transactions contemplated hereby, to use all
reasonable efforts to prevent the entry, enactment or promulgation thereof, as
the case may be.

     (b)  In furtherance and not in limitation of the foregoing, the Company,
Parent, Holdco and Acquisition I shall use their respective best efforts to
resolve such objections, if any, as may be asserted with respect to the
transactions contemplated hereby (including, without limitation, the Mergers)
under any antitrust, competition or trade regulatory laws of any domestic or
foreign government or governmental authority or any multinational authority, or
any regulations issued thereunder ("Antitrust Laws"). Without limiting the
generality of the foregoing, the Company, Parent, Holdco and Acquisition I shall
(i) use their respective best

                                       38


efforts to avoid the entry of, or to have vacated or terminated, any decree,
order, or judgment that would restrain, prevent, or unreasonably delay the
consummation of the transactions contemplated hereby, including, without
limitation, defending through litigation on the merits and through any available
appeals any claim asserted in any court by any party, and (ii) take any and all
steps necessary to avoid (or eliminate) any impediment (including the
institution of proceedings) under any Antitrust Laws that may be asserted by any
Governmental Antitrust Authority with respect to the transactions contemplated
hereby so as to enable the consummation of such transactions to occur reasonably
expeditiously. The steps described in clause (ii) of the preceding sentence
shall include, without limitation, proposing, negotiating, committing to and
effecting (by consent decree, hold separate order or otherwise) the sale,
divestiture or disposition of such assets or businesses of Parent or its
subsidiaries, the Company or its subsidiaries -- or otherwise taking or
committing to take any action that limits its freedom of action with respect to
any of the businesses, product lines or assets of Parent or its affiliates, the
Company or its affiliates -- as may be required in order to avoid the entry of,
or to effect the dissolution of, any injunction, temporary restraining order, or
other order in any suit or proceeding, which would otherwise have the effect of
preventing or unreasonably delaying the consummation of the transactions
contemplated hereby (including, without limitation, the Mergers).
Notwithstanding anything to the contrary contained in this Agreement, neither
Parent, Holdco nor Acquisition I shall be required to take any action pursuant
to Sections 5.6(a) or (b) if the taking of such action would have a material
adverse effect on the business, assets, long-term earning capacity or financial
condition of Parent and the Company (and their subsidiaries), taken as a whole.

     (c)  The Company, Parent, Holdco and Acquisition I shall keep the other
party apprised of the status of matters relating to the completion of the
transactions contemplated hereby (including, without limitation, the Mergers)
and shall reasonably cooperate in connection with obtaining the requisite
approvals, consents or orders of any Governmental Antitrust Authority,
including, without limitation: (i) cooperating with the other parties in
connection with filings under the HSR Act or any other Antitrust Laws,
including, with respect to the party making a filing, (A) providing copies of
all such documents to the non-filing parties and their advisers prior to filing
(other than documents containing confidential business information that shall be
shared only with outside counsel to the non-filing party), and (B) if requested,
to accept all reasonable additions, deletions or changes suggested in connection
with any such filing; (ii) furnishing to each other all information required for
any application or other filing to be made pursuant to the HSR Act or any other
Antitrust Laws in connection with the transactions contemplated by this
Agreement; (iii) promptly notifying the others of, and if in writing furnishing
the others with copies of, any communications from or with any Governmental
Antitrust Authority with respect to the transactions contemplated by this
Agreement (including, without limitation, the Mergers); (iv) permitting the
other parties to review in advance and considering in good faith the views of
one another in connection with any proposed communication with any Governmental
Antitrust Authority in connection with proceedings under or relating to the HSR
Act or any other Antitrust Laws; (v) not agreeing to participate in any meeting
or discussion with any Governmental Antitrust Authority in connection with
proceedings under or relating to the HSR Act or any other Antitrust Laws unless
it consults with the other parties in advance, and, to the extent permitted by
such Governmental Antitrust Authority, gives the other parties the opportunity
to attend and participate thereat; and (vi)

                                       39


consulting and cooperating with one another in connection with any analyses,
appearances, presentations, memoranda, briefs, arguments, opinions and proposals
made or submitted by or on behalf of any party hereto in connection with
proceedings under or relating to the HSR Act or any other Antitrust Laws. If any
party or any affiliate thereof receives a request for additional information or
documentary material from any such Governmental Antitrust Authority with respect
to the transactions contemplated hereby, then such party will endeavor in good
faith to make, or cause to be made, as soon as practicable and after
consultation with the other parties, an appropriate response in compliance with
such request. Parent, Holdco and Acquisition I will advise the Company promptly
in respect of any understandings, undertakings or agreements (oral or written)
which Parent, Holdco and Acquisition I propose to make or enter into with any
Governmental Antitrust Authority in connection with the transactions
contemplated hereby (including, without limitation, the Mergers).

     SECTION 5.7. Indemnification.
                  ---------------

     (a)  After the Effective Time, Parent and the Litton Surviving Corporation
shall jointly and severally indemnify and hold harmless (and shall also advance
expenses as incurred to the fullest extent permitted under applicable law to)
each person who is now or has been prior to the date of the Original Agreement
or who becomes prior to the Effective Time an officer or director of the Company
or any of the Company's subsidiaries (the "Indemnified Persons") against (i)
all losses, claims, damages, costs, expenses (including, without limitation,
counsel fees and expenses), settlement payments or liabilities arising out of or
in connection with any claim, demand, action, suit, proceeding or investigation
based in whole or in part on or arising in whole or in part out of the fact that
such person is or was an officer or director of the Company or any of its
subsidiaries whether or not pertaining to any matter existing or occurring at or
prior to the Effective Time and whether or not asserted or claimed prior to or
at or after the Effective Time ("Indemnified Liabilities") and (ii) all
Indemnified Liabilities based in whole or in part on or arising in whole or in
part out of or pertaining to this Agreement or the transactions contemplated
hereby, in each case to the fullest extent required or permitted under
applicable law or under the Litton Surviving Corporation's Certificate of
Incorporation or Bylaws, it being agreed that the provisions thereof relating to
indemnification and exoneration from liability shall be at least as favorable to
the Indemnified Persons as the current provisions of the Company's Certificate
of Incorporation and Bylaws. The parties hereto intend, to the extent not
prohibited by applicable law, that the indemnification provided for in this
Section 5.7 shall apply without limitation to negligent acts or omissions by an
Indemnified Person. Each Indemnified Person is intended to be a third party
beneficiary of this Section 5.7 and may specifically enforce its terms. This
Section 5.7 shall not limit or otherwise adversely affect any rights any
Indemnified Person may have under any agreement with the Company or under the
Company's Certificate of Incorporation or Bylaws.

     (b)  For six years after the Effective Time, the Litton Surviving
Corporation shall provide directors' and officers' liability insurance in
respect of acts or omissions occurring prior to the Effective Time covering each
such Indemnified Person covered as of the date of the Original Agreement or
thereafter by the Company's directors' and officers' liability insurance policy
on terms with respect to coverage and amounts no less favorable than those of
such policy in effect on the date of the Original Agreement; provided, that if
the aggregate annual premiums

                                       40


for such insurance at any time during such period shall exceed 300% of the per
annum rate of premium paid by the Company as of the date of the Original
Agreement for such insurance, then the Litton Surviving Corporation shall
provide only such coverage as shall then be available at an annual premium equal
to 300% of such current rate.

     SECTION 5.8. Public Announcements. Parent, Holdco, Acquisition I and the
                  --------------------
Company, as the case may be, will consult with one another before issuing any
press release or otherwise making any public statements with respect to the
transactions contemplated by this Agreement, including, without limitation, the
Litton Merger, and shall not issue any such press release or make any such
public statement prior to such consultation except as may be required by
applicable law or by obligations pursuant to any listing agreement with the
NYSE. Parent shall cause Holdco to, and Holdco shall, issue a press release
publicly announcing the Common Stock Consideration prior to the opening of
trading on the second trading day prior to the final Expiration Date.

     SECTION 5.9. Employee Matters.
                  ----------------

     (a)  From and after the Effective Time, Holdco shall assume and honor, and
shall cause the Litton Surviving Corporation to honor, all Employee Plans and
all Employment Agreements in accordance with their terms as in effect
immediately before the Effective Time, subject to any amendment or termination
thereof that may be permitted by such terms. It is acknowledged and agreed that
the consummation of the Offer will constitute a "change of control" for purposes
of those Employee Plans and Employment Agreements containing "change of control"
provisions.

     (b)  For a period of not less than two years following the Effective Time,
Holdco shall provide, or shall cause to be provided, to current and former
employees of the Company and its subsidiaries (the "Company Employees")
compensation and employee benefits that are, in the aggregate, not less
favorable than those provided to Company Employees immediately before the
Effective Time. The foregoing shall not be construed to prevent (i) the
amendment or termination of any particular Employee Plan or Employment Agreement
to the extent permitted by, and in accordance with, its terms as in effect
immediately before the Effective Time, or (ii) the termination of employment or
the reduction of, or other change in, the compensation or employee benefits of
any individual Company Employee.

     (c)  For all purposes under the employee benefit plans of Holdco and its
subsidiaries providing benefits to any Company Employees after the Effective
Time (the "New Plans"), each Company Employee shall be credited with all years
of service for which such Company Employee was credited before the Effective
Time under any similar Company Employee Plans, except to the extent such credit
would result in a duplication of benefits. In addition, and without limiting the
generality of the foregoing: (i) each Company Employee shall be immediately
eligible to participate, without any waiting time, in any and all New Plans to
the extent coverage under such New Plan replaces coverage under a comparable
Company Employee Plan in which such Company Employee participated immediately
before the Effective Time (such plans, collectively, the "Old Plans"); and (ii)
for purposes of each New Plan providing medical, dental, pharmaceutical and/or
vision benefits to any Company Employee, Holdco shall cause all pre-

                                       41


existing condition exclusions and actively-at-work requirements of such New Plan
to be waived for such employee and his or her covered dependents, and Holdco
shall cause any eligible expenses incurred by such employee and his or her
covered dependents during the portion of the plan year of the Old Plan ending on
the date such employee's participation in the corresponding New Plan begins to
be taken into account under such New Plan for purposes of satisfying all
deductible, coinsurance and maximum out-of-pocket requirements applicable to
such employee and his or her covered dependents for the applicable plan year as
if such amounts had been paid in accordance with such New Plan.

     (d)  Without limiting the generality of the foregoing, from and after the
Effective Time, Holdco shall assume and honor, and shall cause the Litton
Surviving Corporation to honor, the obligations of the Company to provide
lifetime benefits under the Company's Supplemental Medical Insurance Plan to the
individuals listed on Schedule 5.9(d). In addition, Holdco agrees not to demand,
and to cause the Litton Surviving Corporation not to demand, repayment of the
loans currently outstanding under the Company's Incentive Loan Program before
December 31, 2001. Finally, Holdco shall continue, or shall cause the Company to
continue, the executive life insurance policies listed in Section 5.9(d) of the
Company Disclosure Schedule in effect for the remaining lifetime of the retired
executives covered thereby, on the terms and conditions now in effect.

     (e)  On or before January 31, 2001, Company shall cause Parent to be
provided with:

          (i)    except to the extent already listed on Schedule 3.11(a) of the
Company Disclosure Schedule a list of all employee benefit plans (as defined in
Section(3) of ERISA) and all bonus, stock option, stock purchase, incentive,
deferred compensation, supplemental retirement, severance and other similar
fringe or employee benefit plans, programs or arrangements maintained or
contributed to by the Company or any of its subsidiaries for the benefit of or
relating to any employee of the Company, or any of its subsidiaries, excluding
plans, programs, agreements and arrangements under which the Company has no
remaining obligations, payroll practices, and any plans, programs, agreements
and arrangements that are required to be maintained by the Company or any of its
subsidiaries under the laws of any foreign jurisdiction;

          (ii)   a copy of the documents and instruments governing each such
plan and the most recent Form 5500 filed with the Internal Revenue Service
except to the extent already provided;

Company Disclosure Schedule, (A) all employment agreements with officers of the
Company; and (B) all agreements with consultants who are individuals obligating
the Company to make annual cash payments in an amount exceeding $30,000. The
Company shall make available to Parent copies (or descriptions in detail
reasonably satisfactory to Parent) of all such agreements, plans, programs and
other arrangements; and

          (iv)   except to the extent already listed in Section 3.11(d) of the
Company Disclosure Schedule, a list of any Employee Plan that is a welfare plan
within the meaning of

                                       42


Section 3(1) of ERISA providing benefits to former employees of the Company or
its ERISA Affiliates other than pursuant to Section 4980B of the Code.

     SECTION 5.10. NYSE Listing. Parent shall use all reasonable efforts to
                   ------------
cause the shares of Holdco Common Stock and Holdco Preferred Stock to be issued
in the Offer to be approved for listing on the NYSE, subject to official notice
of issuance, at the earliest practicable time and in any event prior to the time
when all conditions of the Offer, excluding clause (iii) of the initial

                   -----------------

and Restated Certificate of Incorporation of Holdco in the form of Exhibit B
attached hereto with only such changes thereto as the Company shall reasonably
approve, and (b) the Certificate of Designations of the rights, preferences and
privileges of the Holdco Preferred Stock in the form of Exhibit C attached
hereto with the Secretary of State of the State of Delaware with only such
changes thereto as the Company shall reasonably approve.

     SECTION 5.12. Stockholder Approval of Conversion Shares. Parent or Holdco,
                   -----------------------------------------
as applicable, shall use all reasonable efforts to seek at its 2001 annual
stockholder meeting the requisite stockholder approval pursuant to the rules of
the NYSE for the issuance of shares of Holdco Common Stock upon conversion of
the Holdco Preferred Stock.

conditions of the Agreement and any applicable rules and regulations of the SEC,
including Rules 14e-1(c) under the Exchange Act), Holdco shall not be required

routine application to the Offer, the Mergers or other subsequent business
combination of waiting periods under the HSR Act or Regulation (EEC) No. 4064/89
of the Council of the European Union, that has the effect of (1) making the
acceptance for payment of, or the payment for, some or all of the Shares illegal
or otherwise prohibiting consummation of the Offer, (2) imposing limitations on
the ability of Holdco or Parent to acquire or hold or to exercise effectively
all rights of ownership of the Shares, or effectively to control the business,

exist; or

     (c)  there shall have occurred and continued to exist (i) any general
suspension of trading in, or limitation on prices for, securities on the New

a result of a specified decrease in a market index and suspensions or
limitations resulting from physical damage to or interference with such exchange
not related to market conditions), (ii) the declaration of a banking moratorium
or any suspension of payments in respect of banks in the United States (whether
or not mandatory), (iii) the commencement of a war, armed hostilities or other
international or national calamity directly or indirectly involving the United

of any of the situations described in clauses (i) through (v) inclusive,
existing at the date of the commencement of the Offer, a material acceleration
or worsening thereof; or

     (d)  the Agreement shall have been terminated in accordance with its terms;
or

     (e)  (i)  the representations of the Company contained in the Agreement
shall not be true and correct at and as of consummation of the Offer with the
same effect as if made at and as of such date or if such representations speak
as of an earlier date, as of such earlier date, except, in either such case to
the extent that the breach thereof would not have a Company Material Adverse
Effect, or (ii) the Company shall have failed to comply with its covenants and
agreements contained in the Agreement in all material respects;

     (f)  prior to the purchase of Shares pursuant to the Offer, the Company
Board shall have withdrawn or modified (including by amendment of the Schedule
14D-9) in a manner adverse to Holdco its approval or recommendation of the
Offer, the Agreement or the Litton Merger or shall have recommended another
offer, or shall have adopted any resolution to effect any of the foregoing.

Directors of the Corporation (the "Board of Directors") prior

quotient, then additional directors shall be apportioned as follows:  if such
fraction is one-third, the additional director shall be a member of Class I; and
if such fraction is two-thirds, one of the additional directors shall be a
member of Class I and the other shall be a member of Class II.  Each director

increase in the number of directors, or any vacancies on the Board of Directors
resulting from death, resignation, removal or other causes, shall be filled
solely by the affirmative vote of a majority of the remaining directors then in
office, even though less than a quorum of the Board of Directors. Any director
elected in accordance with the preceding sentence shall hold office for the
remainder of the full term of the class of directors in which the new

cause and only by the affirmative vote of the holders of not less than eighty
percent (80%) of the voting power of all outstanding shares of Voting Stock
entitled to vote in connection with the election of such director, regardless of
class and voting together as a single voting class; provided, however, that
                                                    --------  -------
where such removal is approved by a majority of the Continuing Directors, the
affirmative vote of a majority of the voting power of all outstanding shares of
Voting Stock entitled to vote in connection with the election of such director,
regardless of class and voting together as a single voting class, shall be
required for approval of such removal.

          ELEVENTH:  Any action required or permitted to be taken by the
stockholders of the Corporation must be effected at a duly called Annual Meeting
or at a special meeting of stockholders of the Corporation, unless such action
requiring or permitting shareholder approval is approved by a majority of the
Continuing Directors, in which case such action may be authorized or taken by
the written consent of the holders of outstanding shares of Voting Stock having
not less than the minimum voting power that would be necessary to authorize or
take such action at a meeting of stockholders at which all shares entitled to
vote thereon were present

                                       3

          acquired by such Interested Stockholder, and the price determined in
          accordance with clauses (ii) and (iii) of this paragraph (b) shall be
          subject to appropriate adjustment in the event of any stock dividend,
          stock split, combination of shares or similar event;

               (v)   after such Interested Stockholder has become an Interested
          Stockholder, and prior to the consummation of such Business
          Combination, neither such Interested Stockholder nor any of its
          Affiliates or Associates shall have become the beneficial owner of any
          additional shares of Voting Stock, except (A) as part of the action
          which resulted in such Interested Stockholder becoming an Interested

     Corporation.

          (i) "Fair Market Value" means (i) in the case of stock (A) the highest
     closing sale price during the 30-day period including and immediately

     in question of a share of such stock as determined in good faith by a
     majority of the Continuing Directors (or if there are no Continuing
     Directors, then by a majority of the Board of Directors), and (ii) in the
     case of property other than cash or stock, the fair market value of such
     property on the date in question as determined in good faith by a majority
     of the Continuing Directors (or if there are no Continuing Directors, then

     survives, the phrase "consideration other than cash received or to be
     received" as used in clauses (ii) and (iii) of paragraph (b) of Section 2
     of this Article Fourteenth shall include the shares of Common Stock and/or
     the shares of any other class of Voting Stock retained by the holder of
     such shares.

                                       9


          4.  A majority of the Continuing Directors shall have the power and
duty to determine, for purposes of this Article Fourteenth, on the basis of
information known to them:  (a) whether a person is an Interested Stockholder,
(b) the number of shares of Voting Stock or Subsidiary Stock beneficially owned
by any person, (c) whether a person is an Affiliate or Associate of another
person, (d) whether a person has an agreement, arrangement or understanding with
another person as to the matters referred to in clause (vi) of paragraph (b), or

majority of the Continuing Directors shall have the power and duty to interpret

          5.  Nothing contained in this Article Fourteenth shall be construed to
relieve any Interested Stockholder or any Affiliate or Associate thereof from
any fiduciary obligation imposed by law.

          6.  The fact that any action or transaction complies with the
provisions of this Article Fourteenth shall not be construed to impose any
fiduciary duty, obligation or responsibility on the Board of Directors or any
member thereof to approve such action or transaction or recommend its adoption
or approval to the stockholders of the Corporation, nor shall such compliance
limit, prohibit or otherwise restrict in any manner the Board of Directors, or
any member thereof, with respect to evaluations of, or actions and responses
taken with respect to, such action or transaction.

          FIFTEENTH:  To the maximum extent permissible under Section 262 of the
General Corporation Law of the State of Delaware, the stockholders of the
Corporation shall be entitled to the statutory appraisal rights provided

Stockholder (or any Affiliate or Associate of any Interested Stockholder), which
requires the affirmative vote specified in paragraph (a) of Section Section I of
Article Fourteenth hereof.

          SIXTEENTH:  The provisions set forth in this Article Sixteenth and in
Articles Fourth, Fifth, Sixth, Seventh, Eighth, Ninth, Tenth, Eleventh, Twelfth,
Fourteenth and Fifteenth hereof may not be repealed, rescinded, altered or
amended in any respect, and no other provision or provisions may be adopted
which impair(s) in any respect the operation or effect of any such provision,
except by the affirmative vote of the holders of not less than eighty percent
(80%) of the voting power of all outstanding shares of Voting Stock regardless
of class and voting together as a single voting class and, where such action is
proposed by an Interested Stockholder or by any Associate or Affiliate of an
Interested Stockholder, the affirmative vote of the holders of a majority of the
voting power of all outstanding shares of Voting Stock, regardless of class and
voting together as a single class, other than shares held by the Interested
Stockholder which proposed (or the Affiliate or Associate of which proposed)
such action, or any Affiliate or Associate of such Interested Stockholder,
provided, however, that where such action is approved
- --------  -------

                                       10


by a majority of the Continuing Directors, the affirmative vote of a majority of
the voting power of all outstanding shares of Voting Stock, regardless of class
and voting together as a single voting class, shall be required for approval of
such action.

          SEVENTEENTH:  The Corporation reserves the right to adopt, repeal
rescind, alter or amend in any respect any provision contained in this Amended
and Restated Certificate of Incorporation in the manner now or hereafter
prescribed by applicable law, and all rights conferred on stockholders herein
are granted subject to this reservation. Notwithstanding the preceding sentence,
the provisions set forth in Articles Fourth, Fifth, Sixth, Seventh, Eighth,
Ninth, Tenth, Eleventh, Twelfth, Fourteenth, Fifteenth and Sixteenth may not be
repealed, rescinded, altered or amended in any respect, and no other provision
or provisions may be adopted which impair(s) in any respect the operation or
effect of any such provision, unless such action is approved as specified in
Article Sixteenth hereof.

          EIGHTEENTH:  A director of the Corporation shall not be personally
liable to the Corporation or to its stockholders for monetary damages for breach
of fiduciary duty as a director, except for liability (i) for any breach of the
director's duty of loyalty to the Corporation or to its stockholders, (ii) for
acts or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) under Section 174 of the General Corporation Law
of the State of Delaware, or (iv) for any transaction from which the director
derives any improper personal benefit.  If, after approval of this Article by
the stockholders of the Corporation, the General Corporation Law of the State of
Delaware is amended to authorize the further elimination or limitation of the
liability of directors, then the liability of a director of the Corporation
shall be eliminated or limited to the fullest extent permitted by the General
Corporation Law of the State of Delaware, as so amended. Any repeal or
modification of this Article by the stockholders of the Corporation as provided
in Article Seventeen hereof shall not adversely affect any right or protection
of a director of the Corporation existing at the time of such repeal or
modification."

          3.  The amendment and restatement of this Corporation's Certificate of
Incorporation has been approved by this Corporation's Board of Directors and
stockholders and was duly adopted in accordance with the provisions of Sections
242 and 245 of the General Corporation Law of the State of Delaware.

     Section 2.06.  Notice of Stockholder Business and Nominations. Nominations
                    ----------------------------------------------
of persons for election to the Board and the proposal of business to be
transacted by the stockholders may be made at an annual meeting of stockholders
(a) pursuant to the Corporation's notice with respect to such meeting, (b) by or
at the direction of the Board or (c) by any stockholder of record of the
Corporation who was a stockholder of record at the time of the giving of the
notice provided for in the following paragraph, who is entitled to vote at the
meeting and who has complied with the notice procedures set forth in this
section.

     For nominations or other business to be properly brought before an annual
meeting by a stockholder pursuant to clause (c) of the foregoing paragraph, (1)
the stockholder must have given timely notice thereof in writing to the
Secretary of the Corporation, (2) such business must be a proper matter for
stockholder action under the General Corporation Law of the State of Delaware,
(3) if the stockholder, or the beneficial owner on whose behalf any such
proposal or nomination is made, has provided the Corporation with a Solicitation
Notice, as that term is defined in subclause (c )(iii) of this paragraph, such
stockholder or beneficial owner must, in the case of a proposal, have delivered
a proxy statement and form of proxy to holders of at least the percentage of the
Corporation's voting shares required under applicable law to carry any such
proposal, or, in the case of a nomination or nominations, have delivered a proxy
statement and form of proxy to holders of a percentage of the Corporation's
voting shares reasonably believed by such stockholder or beneficial holder to be
sufficient to elect the nominee or nominees proposed to be nominated by such
stockholder, and must, in either case, have included in such materials the
Solicitation Notice and (4) if no Solicitation Notice relating thereto has been
timely provided pursuant to this section, the stockholder or beneficial owner
proposing such business or nomination must not have solicited a number of
proxies sufficient to have required the delivery of such a Solicitation Notice
under this section.  To be timely, a stockholder's notice shall be delivered to
the Secretary at the principal executive offices of the Corporation not less
than 45 or more than 75 days prior to the first anniversary (the "Anniversary")
of the date on which the Corporation first mailed its proxy materials for the
preceding year's annual meeting of

                                       2


stockholders; provided, however, that if the date of the annual meeting is
advanced more than 30 days prior to or delayed by more than 30 days after the
anniversary of the preceding year's annual meeting, notice by the stockholder to
be more timely must be so delivered not later than the close of business on the
later of (i) the 90th day prior to such annual meeting or (ii) the 10th day
following the day on which public announcement of the date of such meeting is
first made. In no event shall the public announcement of an adjournment of an
annual meeting commence a new time period for the filing of a stockholder's
notice as described herein. Such stockholder's notice shall set forth (a) as to
each person whom the stockholder proposes to nominate for election or reelection
as a director all information relating to such person as would be required to be
disclosed in solicitations of proxies for the election of such nominees as
directors pursuant to Regulation 14A under the Securities Exchange Act of 1934,
as amended (the "Exchange Act") and Rule 14a-11 thereunder (including such
person's written consent to serve as a director if elected); (b) as to any other
business that the stockholder proposes to bring before the meeting, a brief
description of such business, the reasons for conducting such business at the
meeting and any material interest in such business of such stockholder and the
beneficial owner, if any, on whose behalf the proposal is made; (c) as to the
stockholder giving the notice and the beneficial owner, if any, on whose behalf
the nomination or proposal is made (i) the name and address of such stockholder,
as they appear on the Corporation's books, and of such beneficial owner, (ii)
the class and number of shares of the Corporation that are owned beneficially
and of record by such stockholder and such beneficial owner, and (iii) whether
either such stockholder or beneficial owner intends to deliver a proxy statement
and form of proxy to holders of, in the case of a proposal, at least the
percentage of the Corporation's voting shares required under applicable law to
carry the proposal or, in the case of a nomination or nominations, a sufficient
number of holders of the Corporation's voting shares to elect such nominee or
nominees (an affirmative statement of such intent, a "Solicitation Notice").

     Notwithstanding anything in the second sentence of the second paragraph of
this Section 2.06 to the contrary, in the event that the number of directors to
be elected to the Board is increased and there is no public announcement naming
all of the nominees for director or specifying the size of the increased Board
made by the Corporation at least 55 days prior to the Anniversary, a
stockholder's notice required by this Bylaw shall also be considered timely, but
only with respect to nominees for any new positions created by such increase, if
it shall be delivered to the Secretary at the principal executive offices of the
Corporation not later than the close of business on the 10th day following the
day on which such public announcement is first made by the Corporation.

     Only persons nominated in accordance with the procedures set forth in this
Section 2.06 shall be eligible to serve as directors and only such business
shall be conducted at an annual meeting of stockholders as shall have been
brought before the meeting in accordance with the procedures set forth in this
section.  The chair of the meeting shall have the power and the duty to
determine whether a nomination or any business proposed to be brought before the
meeting has been made in accordance with the procedures set forth in these
Bylaws and, if any proposed nomination or business is not in compliance with
these Bylaws, to declare that such defective proposed business or nomination
shall not be presented for stockholder action at the meeting and shall be
disregarded.

                                       3


     Only such business shall be conducted at a special meeting of stockholders
as shall have been brought before the meeting pursuant to the Corporation's
notice of meeting.  Nominations of persons for election to the Board may be made
at a special meeting of stockholders at which directors are to be elected
pursuant to the Corporation's notice of meeting (a) by or at the direction of
the Board or (b) by any stockholder of record of the Corporation who is a
stockholder of record at the time of giving of notice provided for in this
paragraph, who shall be entitled to vote at the meeting and who complies with
the notice procedures set forth in this Section 2.06.  Nominations by
stockholders of persons for election to the Board may be made at such a special
meeting of stockholders if the stockholder's notice required by the second
paragraph of this Section 2.06 shall be delivered to the Secretary at the
principal executive offices of the Corporation not later than the close of
business on the later of the 90th day prior to such special meeting or the 10th
day following on which public announcement is first made of the date of the
special meeting and of the nominees proposed by the Board to be elected at such
meeting.

     For purposes of this section, "public announcement" shall mean disclosure
in a press release reported by the Dow Jones News Service, Associated Press or a
comparable national news service or in a document publicly filed by the
Corporation with the Securities and Exchange Commission pursuant to Section 13,
14 or 15(d) of the Exchange Act.

     Notwithstanding the foregoing provisions of this Section 2.06, a
stockholder shall also comply with all applicable requirements of the Exchange
Act and the rules and regulations thereunder with respect to matters set forth
in this Section 2.06.  Nothing in this Section 2.06 shall be deemed to affect
any rights of stockholders to request inclusion of proposals in the
Corporation's proxy statement pursuant to Rule 14a-8 under the Exchange Act.

     Section 2.07.  Quorum.  At any meeting of stockholders, the presence, in
                    ------
person or by proxy, of the holders of record of a majority of shares then issued
and outstanding and entitled to vote at the meeting shall constitute a quorum
for the transaction of business; provided, however, that this Section 2.07 shall
not affect any different requirement which may exist under statute, pursuant to
the rights of any authorized class or series of stock, or under the Certificate
of Incorporation of the Corporation (the "Certificate") for the vote necessary
for the adoption of any measure governed thereby.  In the absence of a quorum,
the stockholders present in person or by proxy, by majority vote and without
further notice, may adjourn the meeting from time to time until a quorum is
attained.  At any reconvened meeting following such an adjournment at which a
quorum shall be present, any business may be transacted which might have been
transacted at the meeting as originally notified.

     Section 2.08.  Votes Required.  A majority of the votes cast at a duly
                    --------------
called meeting of stockholders, at which a quorum is present, shall be
sufficient to take or authorize action upon any matter which may properly come
before the meeting, unless the vote of a greater or different number thereof is
required by statute, by the rights of any authorized class of stock or by the
Certificate.  Unless the Certificate or a resolution of the Board of Directors
adopted in connection with the issuance of shares of any class or series of
stock provides for a greater or lesser number of votes per share, or limits or
denies voting rights, each outstanding share of stock, regardless of class,
shall be entitled to one vote on each matter submitted to a vote at a meeting of
stockholders.

                                       4


     Section 2.09.  Proxies.  A stockholder may vote the shares owned of record
                    -------
by him either in person or by proxy executed in writing (which shall include
writings sent by telex, telegraph, cable or facsimile transmission) by the
stockholder himself or by his duly authorized attorney-in-fact.  No proxy shall
be valid after three (3) years from its date, unless the proxy provides for a
longer period.  Each proxy shall be in writing, subscribed by the stockholder or
his duly authorized attorney-in-fact, and dated, but it need not be sealed,
witnessed or acknowledged.

     Section 2.10.  Stockholder Action.  Any action required or permitted to be
                    ------------------
taken by the stockholders of the Corporation must be effected at a duly called
annual meeting or special meeting of stockholders of the Corporation, unless
such action requiring or permitting shareholder approval is approved by a
majority of the Continuing Directors (as defined in the Certificate), in which
case such action may be authorized or taken by the written consent of the
holders of outstanding shares of stock having not less than the minimum voting
power that would be necessary to authorize or take such action at a meeting of
stockholders at which all shares entitled to vote thereon were present and
voted, provided all other requirements of applicable law and the Certificate
have been satisfied.

     Section 2.11.  List of Stockholders.  The Secretary of the Corporation
                    --------------------
shall prepare and make (or cause to be prepared and made), at least ten (10)
days before every meeting of stockholders, a complete list of the stockholders
entitled to vote at the meeting, arranged in alphabetical order and showing the
address of, and the number of shares registered in the name of, each
stockholder.  Such list shall be open to the examination of any stockholder, for
any purpose germane to the meeting, during ordinary business hours, for a period
of at least ten (10) days prior to the meeting, either at a place within the
city where the meeting is to be held, which place shall be specified in the
notice of the meeting, or, if not so specified, at the place where the meeting
is to be held.  The list shall also be produced and kept at the time and place
of the meeting during the duration thereof, and may be inspected by any
stockholder who is present.

     Section 2.12.  Inspectors of Election.  In advance of any meeting of
                    ----------------------
stockholders, the Board of Directors may appoint Inspectors of Election to act
at such meeting or at any adjournment or adjournments thereof.  If such
Inspectors are not so appointed or fail or refuse to act, the chairman of any
such meeting may (and, upon the demand of any stockholder or stockholder's
proxy, shall) make such an appointment. The number of Inspectors of Election
shall be one (1) or three (3).  If there are three (3) Inspectors of Election,
the decision, act or certificate of a majority shall be effective and shall
represent the decision, act or certificate of all.  No such Inspector need be a
stockholder of the Corporation.

     The Inspectors of Election shall determine the number of shares
outstanding, the voting power of each, the shares represented at the meeting,
the existence of a quorum and the authenticity, validity and effect of proxies;
they shall receive votes, ballots or consents, hear and determine all challenges
and questions in any way arising in connection with the right to vote, count and
tabulate all votes or consents, determine when the polls shall close and
determine the result; and finally, they shall do such acts as may be proper to
conduct the election or vote with fairness to all stockholders.  On request, the
Inspectors shall make a report in writing to the secretary of the meeting
concerning any challenge, question or other matter as may have been determined
by them and shall execute and deliver to such secretary a certificate of any
fact found by them.

elected in accordance with the preceding sentence shall hold office for the
remainder of the full term of the class of directors in which the new
directorship was created or the vacancy occurred and until such director's
successor shall have been elected and qualified.  No decrease in the number of
directors constituting the Board of Directors shall shorten the term of any
incumbent director.

                    ------
majority of the fixed number of directors shall constitute a quorum for the

director, then the one director shall constitute a quorum. In the absence of a
quorum, the directors present, by majority vote and without notice other than by
announcement, may adjourn the meeting from time to time until a quorum shall be
present. At any reconvened meeting following such an adjournment at which a
quorum shall be present, any business may be transacted which might have been
transacted at the meeting as originally notified.

     Section 3.10.  Votes Required.  Except as otherwise provided by applicable
                    --------------
law or by the Certificate, the vote of a majority of the directors present at a

                    ------------------------
party, or is threatened to be made a party, to any actual or threatened action,
suit, or proceeding, whether civil, criminal, administrative, or investigative
(hereinafter a "proceeding"), by reason of the fact that he or she is or was a
director, officer, employee, or agent of the Corporation (hereinafter an
"indemnitee") shall be indemnified and held harmless by the Corporation to the
fullest extent authorized by the Delaware General Corporation Law, as the same
exists or may hereafter be amended, or by other applicable law as then in
effect, against all expense, liability, and loss (including attorneys' fees,
judgments, fines, ERISA excise taxes or penalties, and amounts paid in
settlement) actually and reasonably incurred or suffered by such indemnitee in

was serving at the request of an executive officer of the Corporation as a
director, officer, employee or agent of another corporation or of a partnership,
joint venture, trust or other enterprise, including service with respect to an
employee benefit plan, shall also be considered an indemnitee for the purposes

                                       16


indemnification provided by this Article shall apply whether or not the basis of

     include the right to have the expenses incurred in defending or preparing
     for any such proceeding in advance of its final disposition (hereinafter an
     "advancement of expenses") paid by the Corporation; provided, however, that
     an advancement of expenses incurred by an indemnitee in his or her capacity
     as a director or officer (and not in any other capacity in which service
     was or is to be rendered by such indemnitee, including, without limitation,
     service to an employee benefit plan) shall be made only upon delivery to
     the Corporation of an undertaking containing such terms and conditions,
     including the requirement of security, as the Board of Directors deems
     appropriate (hereinafter an "undertaking"), by or on behalf of such

     to appeal that such indemnitee is not entitled to be indemnified for such
     expenses under this Article or otherwise; and provided, further, that an
     advancement of expenses shall not be made if the Corporation's Board of
     Directors makes a good faith determination that such payment would violate

     advancement of expenses to employees and agents of the Corporation on such
     terms and conditions as such officers deem appropriate.

after a written claim has been received by the Corporation, except in the case

time thereafter bring suit against the Corporation to recover the unpaid amount

suit, the indemnitee shall also be entitled to be paid the expense of
prosecuting or defending such suit.

     right which any person may have or hereafter acquire under any statute,
     provisions of the Certificate of Incorporation, Bylaw, agreement, vote of
     stockholders or disinterested directors, or otherwise. Notwithstanding any
     amendment to or repeal of this Article, any indemnitee shall be entitled to
     indemnification in accordance with the provisions hereof with respect to
     any acts or omissions of such indemnitee occurring prior to such amendment
     or repeal.

               (b)  The Corporation may maintain insurance, at its expense, to
     protect itself and any past or present director, officer, employee, or
     agent of the Corporation or another corporation, partnership, joint
     venture, trust, or other enterprise against any expense, liability, or
     loss, whether or not the Corporation would have the power to indemnify such
     person against such expense, liability, or loss under the Delaware General
     Corporation Law. The Corporation may enter into contracts with any
     indemnitee in furtherance of the provisions of this Article and may create
     a trust fund, grant a security interest or use other means (including,
     without limitation, a letter of credit) to ensure the payment of such
     amounts as may be necessary to effect indemnification as provided in this

     through 5.04 (a) and (b) hereof, pay the expenses, including attorneys
     fees, incurred by any director, officer, employee or agent of the
     Corporation who is subpoenaed, interviewed or deposed as a witness or
     otherwise incurs expenses in connection with any civil, arbitration,
     criminal, or administrative proceeding or governmental or internal
     investigation to which the Corporation is a party, target, or potentially a
     party or target, or of any such individual who appears as a witness at any
     trial, proceeding or hearing to which the Corporation is a party, if the
     Corporation determines that such payments will benefit the Corporation and
     if, at the time such expenses are incurred by such individual and paid by
     the Corporation, such individual is not a party, and is not threatened to
     be made a party, to such proceeding or investigation.

and registrar may be combined.

it may deem advisable; or the Board of Directors may delegate such power to any
officer or officers or agents of the Corporation; but the Board of Directors or
such officer or officers or agents, in their discretion, may refuse to issue
such a new certificate unless the Corporation is ordered to do so by a court of
competent jurisdiction.

     RESOLVED, that a series of the authorized Preferred Stock, par value $1.00
     per share, of the Corporation be hereby created, and that the designation
     and amount thereof and the voting powers, preferences and relative,
     participating, optional and other special rights of the shares of such

business day, on the first business day thereafter) of January, April, July and
October in each year.  The rate of dividends shall [initially] be [$9.00] per
year per share/1/.  [Thereafter, the rate

- ----------------------------------

/1/  If the initial date of issue is after the 2001 annual meeting of
stockholders, this provision will be modified to reflect the vote at such
meeting.  If Stockholder Approval was obtained, the dividend rate shall be $7.00
per year and the provision relating to future Stockholder Approval will be
deleted.  If Stockholder Approval was not obtained, the initial dividend rate
shall be $9.00 per year and the provision for a future downward adjustment
following Stockholder Approval will be retained.

     If the initial date of issue is before the 2001 annual meeting, the initial
dividend rate shall be $7.00 per year. If Stockholder Approval is obtained at
the 2001 annual meeting, the dividend rate shall remain at such level. If

of the Corporation shall have approved the issuance of all common stock, par

conversion of the Series B Convertible Preferred Stock (such stockholder
approval being referred to herein as the "Stockholder Approval").] [Thereafter,
the rate of dividends shall be increased to $9.00 per share per year after the
October 2001 dividend payment date if the stockholders of the Corporation shall
not have, prior to that time, approved the issuance of all Common Stock issuable
upon conversion of the Series B Convertible Preferred Stock.] [The rate of
dividends shall be decreased to $7.00 per share after the first quarterly
dividend payment date after Stockholder Approval is obtained.] Cash dividends
upon the Series B Convertible Preferred Stock shall commence to accrue and shall
be cumulative from the date of issuance.

     If the dividend for any dividend period shall not have been paid or set
apart in full for the Series B Convertible Preferred Stock, the deficiency shall
be fully paid or set apart for payment before (i) any distributions or
dividends, other than distributions or dividends paid in stock ranking junior to
the Series B Convertible Preferred Stock as to dividends, redemption payments
and rights upon liquidation, dissolution or winding up of the Corporation, shall
be paid upon or set apart for Common Stock or stock of any other class or series
of Preferred Stock ranking junior to the Series B Convertible Preferred Stock as

dissolution or winding up of the Corporation shall be redeemed, repurchased or
otherwise acquired for any consideration other than stock ranking junior to the
Series B Preferred Stock as to dividends, redemption payments and rights upon
liquidation, dissolution or winding up of the Corporation. No distribution or
dividend shall be paid upon, or declared and set apart for, any shares of
Preferred Stock ranking on a parity with the Series B Convertible Preferred
Stock as to dividends, redemption payments or rights upon liquidation,
dissolution or winding up of the Corporation for any dividend period unless at
the same time a like proportionate distribution or dividend for the same or
similar dividend period, ratably in proportion to the respective annual
dividends fixed therefor, shall be paid upon or declared and set apart for all
shares of Preferred Stock of all series so ranking then outstanding and entitled
to receive such dividend.

     Section 3.  Voting Rights.  Except as provided herein or as may otherwise
                 -------------
be required by law, the holders of shares of Series B Convertible Preferred
Stock shall not be entitled to any voting rights as stockholders with respect to
such shares.

     (a) So long as any shares of Series B Convertible Preferred Stock shall be
outstanding, the Corporation shall not, without the affirmative vote of the
holders of at least two-thirds of the aggregate number of shares of Series B
Convertible Preferred Stock at the time

                                       2


outstanding, by an amendment to the Restated Certificate of Incorporation, by
merger or consolidation, or in any other manner:

          (i)    authorize any class or series of stock ranking prior to the
     Series B Convertible Preferred Stock as to dividends, redemption payments
     or rights upon liquidation, dissolution or winding up of the Corporation;

          (ii)   alter or change the preferences, special rights, or powers
     given to the Series B Convertible Preferred Stock so as to affect such
     class of stock adversely, but nothing in this clause (ii) shall require
     such a class vote (x) in connection with any increase in the total number
     of authorized shares of Common Stock or Preferred Stock; (y) in connection
     with the authorization or increase in the total number of authorized shares
     of any class of stock ranking on a parity with the Series B Convertible
     Preferred Stock; or (z) in connection with the fixing of any of the
     particulars of shares of any other series of Preferred Stock ranking on a
     parity with the Series B Convertible Preferred Stock that may be fixed by
     the Board of Directors as provided in Article FOURTH of the Certificate of
     Incorporation; or

          (iii)  directly or indirectly purchase or redeem less than all of the
     Series B Convertible Preferred Stock at the time outstanding unless the
     full dividends to which all shares of the Series B Convertible Preferred
     Stock then outstanding shall then be entitled shall have been paid or
     declared and a sum sufficient for the payment thereof set apart.

     (b) If and whenever accrued dividends on the Series B Convertible Preferred
Stock shall not have been paid or declared and a sum sufficient for the payment
thereof set aside for six quarterly dividend periods (whether or not
consecutive), then and in such event, the holders of the Series B Convertible
Preferred Stock, voting separately as a class, shall be entitled to elect two
directors at any annual meeting of the stockholders or any special meeting held
in place thereof, or at a special meeting of the holders of the Series B
Convertible Preferred Stock called as hereinafter provided. Such right of the
holders of the Series B Convertible Preferred Stock to elect two directors may
be exercised until the dividends in default on the Series B Convertible
Preferred Stock shall have been paid in full or funds sufficient therefor set
aside; and when so paid or provided for, then the right of the holders of the
Series B Convertible Preferred Stock to elect such number of directors shall
cease, but subject always to the same provisions for the vesting of such voting
rights in the case of any such future default or defaults. At any time after
such voting power shall have so vested in the holders of the Series B
Convertible Preferred Stock, the Secretary of the Corporation may, and upon the
written request of the holders of record of ten percent (10%) or more in amount
of the Series B Convertible Preferred Stock then outstanding addressed to him at
the principal executive office of the Corporation shall, call a special meeting
of the holders of the Series B Convertible Preferred Stock for the election of
the directors to be elected by them as hereinafter provided, to be held within
sixty (60) days after delivery of such request and at the place and upon the
notice provided by law and in the bylaws of the Corporation for the holding of
meetings of stockholders; provided, however, that the Secretary shall not be
                          --------  -------
required to call such special meeting in the case of any such request received
less than ninety (90) days before the date fixed for the next ensuing annual
meeting of stockholders. If at any such annual or special meeting or any
adjournment thereof the holders of at least a majority of the Series B
Convertible Preferred Stock then outstanding and entitled to

                                       3


vote thereat shall be present or represented by proxy, then, by vote of the
holders of at least a majority of the Series B Convertible Preferred Stock
present or so represented at such meeting, the then authorized number of
directors of the Corporation shall be increased by two, and the holders of the
Series B Convertible Preferred Stock shall be entitled to elect the additional
directors so provided for. The directors so elected shall serve until the next
annual meeting or until their respective successors shall be elected and shall
qualify; provided, however, that whenever the holders of the Series B
         -------- --------
Convertible Preferred Stock shall be divested of voting power as above provided,
the terms of office of all persons elected as directors by the holders of the
Series B Convertible Preferred Stock as a class shall forthwith terminate and
the number of the Board of Directors shall be reduced accordingly.

     (c) If, during any interval between any special meeting of the holders of
the Series B Convertible Preferred Stock for the election of directors to be
elected by them as provided in this Section 3 and the next ensuing annual
meeting of stockholders, or between annual meetings of stockholders for the
election of directors, and while the holders of the Series B Convertible
Preferred Stock shall be entitled to elect two directors, the number of
directors who have been elected by the holders of the Series B Convertible
Preferred Stock shall, by reason of resignation, death, or removal, be less than
the total number of directors subject to election by the holders of the Series B
Convertible Preferred Stock, (i) the vacancy or vacancies in the directors
elected by the holders of the Series B Convertible Preferred Stock shall be
filled by the remaining director then in office, if any, who was elected by the
holders of the Series B Convertible Preferred Stock, although less than a
quorum, and (ii) if not so filled within sixty (60) days after the creation
thereof, the Secretary of the Corporation shall call a special meeting of the
holders of the Series B Convertible Preferred Stock and such vacancy or
vacancies shall be filled at such special meeting.  Any director elected to fill
any such vacancy by the remaining director then in office may be removed from
office by vote of the holders of a majority of the shares of the Series B
Convertible Preferred Stock.  A special meeting of the holders of the Series B
Convertible Preferred Stock may be called by a majority vote of the Board of
Directors for the purpose of removing such director.  The Secretary of the
Corporation shall, in any event, within ten (10) days after delivery to the
Corporation at its principal office of a request to such effect signed by the
holders of at least ten percent (10%) of the outstanding shares of the Series B
Convertible Preferred Stock, call a special meeting for such purpose to be held
within sixty (60) days after delivery of such request; provided, however, that
                                                       --------  -------
the Secretary shall not be required to call such a special meeting in the case
of any such request received less than ninety (90) days before the date fixed
for the next ensuing annual meeting of stockholders.

     Section 4.  Redemption.
                 ----------

     (a) Shares of Series B Convertible Preferred Stock shall not be redeemable
except as follows:

          (i)  All, but not less than all, of the shares of Series B Convertible
     Preferred Stock shall be redeemed for cash in an amount equal to (X) if
     prior to Stockholder Approval, the greater of (a) the Liquidation Value
     plus all accrued and unpaid dividends with respect to such shares, whether
     or not declared, and (b) the Current Market Price of the number of shares
     of Common Stock which would be issued to such holders if all shares of
     Series B Convertible Preferred Stock were converted into Common Stock on
     the

                                       4


     Redemption Date pursuant to Section 8; and (Y) after Stockholder
     Approval, the Liquidation Value plus all dividends with respect to such
     shares, whether or not declared, accrued and unpaid as of the Redemption
     Date, as defined below, on the first day after the twentieth anniversary of
     the initial issuance of the Series B Convertible Preferred Stock.

          (ii)  All, but not less than all, of the shares of Series B
     Convertible Preferred Stock may be redeemed at the option of the
     Corporation at any time after the seventh anniversary of the initial
     issuance of the Series B Convertible Preferred Stock.  Any redemption
     pursuant to this clause (ii) shall be solely for Common Stock of the
     Corporation and at the Redemption Date each holder of shares of Series B
     Convertible Preferred Stock shall be entitled to receive, in exchange and
     upon surrender of the certificate therefor, that number of fully paid and
     nonassessable shares of Common Stock determined by dividing (X) if prior to
     Stockholder Approval, the greater of (a) the Liquidation Value plus all
     accrued and unpaid dividends with respect to such shares, whether or not
     declared, and (b) the Current Market Price of the number of shares of
     Common Stock which would be issued if all shares of Series B Convertible
     Preferred Stock were converted into Common Stock pursuant to Section 8 on
     the Redemption Date; or (Y) if after Stockholder Approval, the Liquidation
     Value plus all accrued and unpaid dividends with respect to such shares,
     whether or not declared thereon to the Redemption Date, by (Z) the Current
     Market Price of the Common Stock as of the Redemption Date; provided,
                                                                 --------
     however, that if prior to the Redemption Date there shall have occurred a
     -------
     Transaction, as defined in Section 8(b)(iii), the consideration deliverable
     in any such exchange shall be the Alternate Consideration as provided in
     Section 12.

     (b) Notice of every mandatory or optional redemption shall be mailed at
least thirty (30) days but not more than fifty (50) days prior to the Redemption
Date to the holders of record of the shares of Series B Convertible Preferred
Stock so to be redeemed at their respective addresses as they appear upon the
books of the Corporation.  Each such notice shall specify the date on which such
redemption shall be effective (the "Redemption Date"), the redemption price or
manner of calculating the redemption price and the place where certificates for
the Series B Convertible Preferred Stock are to be surrendered for cancellation.

     (c) On the date that redemption is being made pursuant to paragraph (a) of
this Section 4, the Corporation shall deposit for the benefit of the holders of
shares of Series B Convertible Preferred Stock the funds, or stock certificates
for Common Stock, necessary for such redemption with a bank or trust company in
the Borough of Manhattan, the City of New York, having a capital and surplus of
at least $1,000,000,000.  Dividends paid on Common Stock held for the benefit of
the holders of shares of Series B Convertible Preferred Stock hereunder shall be
held for the benefit of such holders and paid over, without interest, on
surrender of certificates for the Series B Convertible Preferred Stock.  Any
monies or stock certificates so deposited by the Corporation and unclaimed at
the end of one year from the Redemption Date shall revert to the Corporation.
After such reversion, any such bank or trust company shall, upon demand, pay
over to the Corporation such unclaimed amounts or deliver such stock
certificates and thereupon such bank or trust company shall be relieved of all
responsibility in respect thereof and any holder of shares of Series B
Convertible Preferred Stock shall look only to the Corporation for the payment
of the redemption price. Any interest accrued on funds deposited

                                       5


pursuant to this paragraph (c) shall be paid from time to time to the
Corporation for its own account.

     (d) Upon the deposit of funds or certificates for Common Stock pursuant to
paragraph (c) in respect of shares of Series B Convertible Preferred Stock being
redeemed pursuant to paragraph (a) of this Section 4, notwithstanding that any
certificates for such shares shall not have been surrendered for cancellation,
the shares represented thereby shall on and after the Redemption Date no longer
be deemed outstanding, and all rights of the holders of shares of Series B
Convertible Preferred Stock shall cease and terminate, excepting only the right
to receive the redemption price therefor.  Nothing in this Section 4 shall limit
the right of a holder to convert shares of Series B Convertible Preferred Stock
pursuant to Section 8 at any time prior to the Redemption Date, even if such
shares have been called for redemption pursuant to Section 4(a).

     (e) In connection with any redemption pursuant to clause (ii) of paragraph
(a) of this Section 4, no fraction of a share of common stock shall be issued,
but in lieu thereof the Corporation shall pay a cash adjustment in respect of
such fractional interest in an amount equal to such fractional interest
multiplied by the Current Market Price per share of Common Stock on the
Redemption Date.

     Section 5.  Fundamental Change in Control.
                 -----------------------------

     (a) Not later than 10 business days following a Fundamental Change in
Control, as defined below, the Corporation shall mail notice to the holders of
Series B Convertible Preferred Stock stating that a Fundamental Change in
Control has occurred and advising such holders of their right to exchange (the
"Exchange Right") any and all shares of Series B Convertible Preferred Stock for
shares of Common Stock as provided herein; provided, however, that if prior to
                                           --------  -------
the Exchange Date (as defined below) there shall have occurred a Transaction, as
defined in Section 8(b)(iii), the consideration deliverable in any such exchange
shall be the Alternate Consideration as provided in Section 12.  Such notice
shall state: (i) the date on which such exchanges shall be effective (the
"Exchange Date"), which shall be the 21st business day from the date of giving
such notice; (ii) the number of shares of Common Stock (or Alternate
Consideration) for which each share of Series B Convertible Preferred Stock may
be exchanged; and (iii) the method by which each holder may give notice of its
exercise of the Exchange Right; and (iv) the method and place for delivery of
certificates for Series B Convertible Preferred Stock in connection with
exchanges pursuant hereto.  For a period of twenty (20) business days following
the notice provided herein, each holder of Series B Convertible Preferred Stock
may exercise the Exchange Right as provided herein.

     (b) Pursuant to the Exchange Right, each share of Series B Convertible
Preferred Stock shall be exchanged for that number of shares of Common Stock
determined by dividing an amount equal to (X) if prior to Stockholder Approval,
the greater of (a) the Liquidation Value plus all dividends accrued and unpaid
with respect to such share as of the Exchange Date, whether or not declared, and
(b) the Current Market Price of the number of shares of Common Stock which would
be issued if such share of Series B Convertible Preferred Stock were converted
into Common Stock pursuant to Section 8 on the Exchange Date; or (Y) if after
Stockholder Approval, the Liquidation Value plus all dividends accrued and
unpaid with respect

                                       6


to such share as of the Exchange Date, whether or not declared, in each case by
the Current Market Price per share of Common Stock as of the Exchange Date.

     (c) The holder of any share of Series B Convertible Preferred Stock may
exercise the Exchange Right by surrendering for such purpose to the Corporation,
at its principal office or at such other office or agency maintained by the
Corporation for that purpose, a certificate or certificates representing the
shares of Series B Convertible Preferred Stock to be exchanged accompanied by a
written notice stating that such holder elects to exercise the Exchange Right as
to all or a specified number of such shares in accordance with this Section 5
and specifying the name or names in which such holder wishes the certificate or
certificates for shares of Common Stock to which such holder is entitled to be
issued and such other customary documents as are necessary to effect the
exchange.  In case such notice shall specify a name or names other than that of
such holder, such notice shall be accompanied by payment of all transfer taxes
payable upon the issuance in such name or names of shares of Common Stock to
which such holder has become entitled. Other than such taxes, the Corporation
will pay any and all issue and other taxes (other than taxes based on income)
that may be payable in respect of any issue or delivery of shares of Common
Stock to which such holder has become entitled on exchange of shares of Series B
Convertible Preferred Stock pursuant hereto.  As promptly as practicable, and in
any event within five (5) business days after the surrender of such certificate
or certificates and the receipt of such notice relating thereto and, if
applicable, payment of all transfer taxes (or the demonstration to the
satisfaction of the Corporation that such taxes have been paid), the Corporation
shall deliver or cause to be delivered certificates representing the number of
validly issued, fully paid and nonassessable shares of Common Stock to which the
holder of shares of Series B Convertible Preferred Stock so exchanged shall be
entitled.

     (d) From and after the Exchange Date, a holder of shares of Series B
Convertible Preferred Stock who has elected to exchange such shares for Common
Stock as herein provided shall have no voting or other rights with respect to
the shares of Series B Convertible Preferred Stock subject thereto, other than
the right to receive the Common Stock provided herein upon delivery of the
certificate or certificates evidencing shares of Series B Convertible Preferred
Stock.

     (e) In connection with the exchange of any shares of Series B Convertible
Preferred Stock, no fraction of a share of Common Stock shall be issued, but in
lieu thereof the Corporation shall pay a cash adjustment in respect of such
fractional interest in an amount equal to such fractional interest multiplied by
the Current Market Price per share of Common Stock on the Exchange Date.

     (f) The Corporation shall at all times reserve and keep available out of
its authorized and unissued Common Stock, solely for the purpose of the Exchange
Rights provided herein, such number of shares of Common Stock as shall from time
to time be sufficient to effect the exchange provided herein.  The Corporation
shall from time to time, in accordance with the laws of Delaware, increase the
authorized amount of Common Stock if at any time the number of authorized shares
of Common Stock remaining unissued shall not be sufficient to permit the
exchange of all then outstanding shares of Series B Convertible Preferred Stock.

                                       7


     (g) As used herein, the term "Fundamental Change in Control" shall mean any
merger, consolidation, sale of all or substantially all of the Corporation's
assets, liquidation or recapitalization (other than solely a change in the par
value of equity securities) of the Common Stock in which more than one-third of
the previously outstanding Common Stock shall be changed into or exchanged for
cash, property or securities other than capital stock of the Corporation or
another corporation ("Non Stock Consideration").  For purposes of the preceding
sentence, any transaction in which shares of Common Stock shall be changed into
or exchanged for a combination of Non Stock Consideration and capital stock of
the Corporation or another corporation shall be deemed to have involved the
exchange of a number of shares of Common Stock for Non Stock Consideration equal
to the total number of shares exchanged multiplied by a fraction in which the
numerator is the Fair Market Value of the Non Stock Consideration and the
denominator is the Fair Market Value of the total consideration in such
exchange, each as determined by a resolution of the Board of Directors of the
Corporation.

     Section 6.  Reacquired Shares.  Any shares of Series B Convertible
                 -----------------
Preferred Stock converted, redeemed, exchanged, purchased or otherwise acquired
by the Corporation in any manner whatsoever shall be retired and canceled
promptly after the acquisition thereof.  All such shares shall upon their
cancellation, and upon the filing of an appropriate certificate with the
Secretary of State of the State of Delaware, become authorized but unissued
shares of Preferred Stock, par value $1.00 per share, of the Corporation and may
be reissued as part of another series of Preferred Stock, par value $1.00 per
share, of the Corporation subject to the conditions or restrictions on issuance
set forth herein.

     Section 7.  Liquidation, Dissolution or Winding Up.
                 --------------------------------------

     (a) Except as provided in paragraph (b) of this Section 7, upon any
voluntary or involuntary liquidation, dissolution or winding up of the
Corporation, no distribution shall be made (i) to the holders of shares of
capital stock of the Corporation ranking junior as to dividends, redemption
payments and rights upon liquidation, dissolution or winding up of the
Corporation to the Series B Convertible Preferred Stock unless, prior thereto,
the holders of shares of Series B Convertible Preferred Stock shall have
received (X) if prior to Stockholder Approval, the greater of (a) the
Liquidation Value plus all accrued and unpaid dividends with respect to such
shares, whether or not declared, and (b) the amount which would be distributed
to such holders if all shares of Series B Convertible Preferred Stock had been
converted into Common Stock pursuant to Section 8; and (Y) after Stockholder
Approval, the Liquidation Value plus all accrued and unpaid dividends with
respect to such shares, whether or not declared or (ii) to the holders of shares
of capital stock ranking on a parity with the Series B Convertible Preferred
Stock as to dividends, redemption payments and rights upon liquidation,
dissolution or winding up of the Corporation, except distributions made ratably
on the Series B Convertible Preferred Stock and all such parity stock in
proportion to the total amounts to which the holders of all such shares are
entitled upon such liquidation, dissolution or winding up.  The Liquidation
Value shall be $100.00 per share.

     (b) If the Corporation shall commence a voluntary case under the Federal
bankruptcy laws or any other applicable Federal or State bankruptcy, insolvency
or similar law, or consent to the entry of an order for relief in an involuntary
case under any such law or to the appointment of a receiver, liquidator,
assignee, custodian, trustee, sequestrator (or other similar official) of the

                                       8


Corporation or of any substantial part of its property, or make an assignment
for the benefit of its creditors, or admit in writing its inability to pay its
debts generally as they become due, or if a decree or order for relief in
respect of the Corporation shall be entered by a court having jurisdiction in
the premises in an involuntary case under the Federal bankruptcy laws or any
other applicable Federal or State bankruptcy, insolvency or similar law, or
appointing a receiver, liquidator, assignee, custodian, trustee, sequestrator
(or other similar official) of the Corporation or of any substantial part of its
property, or ordering the winding up or liquidation of its affairs, and on
account of any such event the Corporation shall liquidate, dissolve or wind up,
no distribution shall be made (i) to the holders of shares of capital stock of
the Corporation ranking junior to the Series B Convertible Preferred Stock as to
dividends, redemption payments and rights upon liquidation, dissolution or
winding up of the Corporation unless, prior thereto, the holders of shares of
Series B Convertible Preferred Stock shall have received (X) if prior to
Stockholder Approval, the greater of (a) the Liquidation Value plus all accrued
and unpaid dividends with respect to such shares, whether or not declared, and
(b) the amount which would be distributed to such holders if all shares of
Series B Convertible Preferred Stock had been converted into Common Stock
pursuant to Section 8; and (Y) after Stockholder Approval, the Liquidation Value
plus all accrued and unpaid dividends with respect to such shares, whether or
not declared, or (ii) to the holders of shares of capital stock ranking on a
parity with the Series B Convertible Preferred Stock as to dividends, redemption
payments and rights upon liquidation, dissolution or winding up of the
Corporation, except distributions made ratably on the Series B Convertible
Preferred Stock and all such parity stock in proportion to the total amounts to
which the holders of all such shares are entitled upon such liquidation,
dissolution or winding up.

     (c) Neither the consolidation, merger or other business combination of the
Corporation with or into any other Person or Persons nor the sale of all or
substantially all of the assets of the Corporation shall be deemed to be a
liquidation, dissolution or winding up of the Corporation for purposes of this
Section 7.

     Section 8.  Conversion.  Subject to the condition that the Stockholder
                 ----------
Approval shall first have been obtained, each share of Series B Convertible
Preferred Stock shall be convertible, at any time, at the option of the holder
thereof into the right to receive shares of Common Stock, on the terms and
conditions set forth in this Section 8.

     (a) Subject to the provisions for adjustment hereinafter set forth, each
share of Series B Convertible Preferred Stock shall be converted into the right
to receive a number of fully paid and nonassessable shares of Common Stock,
which shall be equal to the Liquidation Value divided by the Conversion Price,
as herein defined.  Initially the Conversion Price shall be 127% of
$______________./2/  The Conversion Price shall be subject to adjustment as
provided in this Section 8.

     (b) The Conversion Price shall be subject to adjustment from time to time
as follows:

- ----------------------

/2/  The blank will be filled with an amount equal to the Average Parent Price,
as defined in the Amended and Restated Agreement and Plan of Merger.

                                       9


          (i)  In case the Corporation shall at any time or from time to time
     declare a dividend, or make a distribution, on the outstanding shares of
     Common Stock in shares of Common Stock or subdivide or reclassify the
     outstanding shares of Common Stock into a greater number of shares or
     combine or reclassify the outstanding shares of Common Stock into a smaller
     number of shares of Common Stock, or shall declare, order, pay or make a
     dividend or other distribution on any other class or series of capital
     stock, which dividend or distribution includes Common Stock then, and in
     each such case, the Conversion Price shall be adjusted to equal the number
     determined by multiplying (A) the Conversion Price immediately prior to
     such adjustment by (B) a fraction, the denominator of which shall be the
     number of shares of Common Stock outstanding immediately after such
     dividend, distribution, subdivision or reclassification, and the numerator
     of which shall be the number of shares of Common Stock outstanding
     immediately before such dividend, distribution, subdivision or
     reclassification.  An adjustment made pursuant to this clause (i) shall
     become effective (A) in the case of any such dividend or distribution,
     immediately after the close of business on the record date for the
     determination of holders of shares of Common Stock entitled to receive such
     dividend or distribution, or (B) in the case of any such subdivision,
     reclassification or combination, at the close of business on the day upon
     which such corporate action becomes effective.

          (ii) In case the Corporation shall at any time or from time to time
     declare, order, pay or make a dividend or other distribution (including,
     without limitation, any distribution of stock, evidences of indebtedness or
     other securities, cash or other property or rights or warrants to subscribe
     for securities of the Corporation or any of its Subsidiaries by way of
     distribution, dividend or spinoff, but excluding regular ordinary cash
     dividends as may be declared from time to time by the Corporation) on its
     Common Stock, other than a distribution or dividend of shares of Common
     Stock that is referred to in clause (i) of this paragraph (b), then, and in
     each such case, the Conversion Price shall be adjusted to equal the number
     determined by multiplying (A) the Conversion Price immediately prior to the
     record date fixed for the determination of stockholders entitled to receive
     such dividend or distribution by (B) a fraction, the denominator of which
     shall be the Current Market Price per share of Common Stock on the last
     Trading Day on which purchasers of Common Stock in regular way trading
     would be entitled to receive such dividend or distribution and the
     numerator of which shall be the Current Market Price per share of Common
     Stock on the first Trading Day on which purchasers of Common Stock in
     regular way trading would not be entitled to receive such dividend or
     distribution (the "Ex-dividend Date"); provided that the fraction
     determined by the foregoing clause (B) shall not be greater than 1.  An
     adjustment made pursuant to this clause (ii) shall be effective at the
     close of business on the Ex-dividend Date.  If the Corporation completes a
     tender offer or otherwise repurchases shares of Common Stock in a single
     transaction or a related series of transactions, provided such tender offer
     or offer to repurchase is open to all or substantially all holders of
     Common Stock (not including open market or other selective repurchase
     programs), the Conversion Price shall be adjusted as though (A) the
     Corporation had effected a reverse split of the Common Stock to reduce the
     number of shares of Common Stock outstanding from (x) the number
     outstanding immediately prior to the completion of the tender offer or the
     first repurchase for which the adjustment is being made to (y) the number
     outstanding

                                       10


     immediately after the completion of the tender offer or the last
     repurchase for which the adjustment is being made and (B) the Corporation
     had paid a dividend on the Common Stock outstanding immediately after
     completion of the tender offer or the last repurchase for which the
     adjustment is being made in an aggregate amount equal to the aggregate
     consideration paid by the Corporation pursuant to the tender offer or the
     repurchases for which the adjustment is being made (the "Aggregate
     Consideration"); provided that in no event shall the Conversion Price be
     increased as a result of the foregoing adjustment. In applying the first
     two sentences of this Section 8(b)(ii) to the event described in clause (B)
     of the preceding sentence, the Current Market Price of the Common Stock on
     the date immediately following the closing of any such tender offer or on
     the date of the last repurchase shall be taken as the value of the Common
     Stock on the Ex-Dividend Date, and the value of the Common Stock on the day
     preceding the Ex-Dividend Date shall be assumed to be equal to the sum of
     (x) the value on the Ex-Dividend Date and (y) the per share amount of the
     dividend described in such clause (B) computed by dividing the Aggregate
     Consideration by the number of shares of Common Stock outstanding after the
     completion of such tender offer or repurchase. In the event that any of the
     consideration paid by the Corporation in any tender offer or repurchase to
     which this Section 8(b)(ii) applies is in a form other than cash, the value
     of such consideration shall be determined by an independent investment
     banking firm of nationally recognized standing to be selected by the Board
     of Directors of the Corporation.

          (iii) In case at any time the Corporation shall be a party to any
     transaction (including, without limitation, a merger, consolidation, sale
     of all or substantially all of the Corporation's assets, liquidation or
     recapitalization (other than solely a change in the par value of equity
     securities) of the Common Stock and excluding any transaction to which
     clause (i) or (ii) of this paragraph (b) applies) in which the previously
     outstanding Common Stock shall be changed into or exchanged for different
     securities of the Corporation or common stock or other securities of
     another corporation or interests in a noncorporate entity or other property
     (including cash) or any combination of any of the foregoing (each such
     transaction being herein called the "Transaction"), then each Share of
     Series B Convertible Preferred Stock then outstanding shall thereafter be
     convertible into, in lieu of the Common Stock issuable upon such conversion
     prior to consummation of such Transaction, the kind and amount of shares of
     stock and other securities and property receivable (including cash) upon
     the consummation of such Transaction by a holder of that number of shares
     of Common Stock into which one share of Series B Convertible Preferred
     Stock would have been convertible (without giving effect to any restriction
     on convertibility) immediately prior to such Transaction including, on a
     pro rata basis, the cash, securities or property received by holders of
     Common Stock in any such transaction.  The Corporation shall not be a party
     to a Transaction that does not expressly contemplate and provide for the
     foregoing.

          (iv)  If any event occurs as to which the foregoing provisions of this
     Section 8(b) are not strictly applicable but the failure to make any
     adjustment to the Conversion Price or other conversion mechanics would not
     fully and equitably protect the conversion rights of the Series B Preferred
     Stock in accordance with the essential intent and principles of such
     provisions, then in each such case the Board of Directors of the
     Corporation shall make such appropriate adjustments to the Conversion Price
     or other

                                       11


     conversion mechanics (on a basis consistent with the essential intent
     and principles established in this Section 8) as may be necessary to fully
     and equitably preserve, without dilution or diminution, the conversion
     rights of the Series B Convertible Preferred Stock.

     (c) If any adjustment required pursuant to this Section 8 would result in
an increase or decrease of less than 1% in the Conversion Price, the amount of
any such adjustment shall be carried forward and adjustment with respect thereto
shall be made at the time of and together with any subsequent adjustment, which,
together with such amount and any other amount or amounts so carried forward,
shall aggregate at least 1% of the Conversion Price.

     (d) The Board of Directors may at its option increase the number of shares
of Common Stock into which each share of Series B Convertible Preferred Stock
may be converted, in addition to the adjustments required by this Section 8, as
shall be determined by it (as evidenced by a resolution of the Board of
Directors) to be advisable in order to avoid or diminish any income deemed to be
received by any holder for federal income tax purposes of shares of Common Stock
or Series B Convertible Preferred Stock resulting from any events or occurrences
giving rise to adjustments pursuant to this Section 8 or from any other similar
event.

     (e) The holder of any shares of Series B Convertible Preferred Stock may
exercise his right to receive in respect of such shares the shares of Common
Stock or other property or securities, as the case may be, to which such holder
is entitled by surrendering for such purpose to the Corporation, at its
principal office or at such other office or agency maintained by the Corporation
for that purpose, a certificate or certificates representing the shares of
Series B Convertible Preferred Stock to be converted, accompanied by a written
notice stating that such holder elects to convert all or a specified number of
such shares in accordance with this Section 8 and specifying the name or names
in which such holder wishes the certificate or certificates for shares of Common
Stock or other property or securities, as the case may be, to which such holder
is entitled to be issued and such other customary documents as are necessary to
effect the conversion.  In case such notice shall specify a name or names other
than that of such holder, such notice shall be accompanied by payment of all
transfer taxes payable upon the issuance in such name or names of shares of
Common Stock or other property or securities, as the case may be, to which such
holder has become entitled.  Other than such taxes, the Corporation will pay any
and all issue and other taxes (other than taxes based on income) that may be
payable in respect of any issue or delivery of shares of Common Stock or such
other property or securities, as the case may be, to which such holder has
become entitled on conversion of Series B Convertible Preferred Stock pursuant
hereto.  As promptly as practicable, and in any event within five (5) business
days after the surrender of such certificate or certificates and the receipt of
such notice relating thereto and, if applicable, payment of all transfer taxes
(or the demonstration to the satisfaction of the Corporation that such taxes
have been paid), the Corporation shall deliver or cause to be delivered
certificates representing the number of validly issued, fully paid and
nonassessable full shares of Common Stock to which the holder of shares of
Series B Convertible Preferred Stock so converted shall be entitled or such
other property or assets, as the case may be, to which such holder has become
entitled.  The date upon which a holder delivers to the Corporation a notice of
conversion and the accompanying documents referred to above is referred to
herein as the "Conversion Date."

                                       12


     (f) From and after the Conversion Date, a holder of shares of Series B
Convertible Preferred Stock shall have no voting or other rights with respect to
the shares of Series B Convertible Stock subject thereto, other than the right
to receive upon delivery of the certificate or certificates evidencing shares of
Series B Convertible Preferred Stock as provided by paragraph 8(e), the
securities or property described in this Section 8.

     (g) In connection with the conversion of any shares of Series B Convertible
Preferred Stock, no fraction of a share of Common Stock shall be issued, but in
lieu thereof the Corporation shall pay a cash adjustment in respect of such
fractional interest in an amount equal to such fractional interest multiplied by
the Current Market Price per share of Common Stock on the day on which such
shares of Series B Convertible Preferred Stock are deemed to have been
converted.

     (h) Upon conversion of any shares of Series B Convertible Preferred Stock,
if there are any accrued but unpaid dividends thereon, the Corporation shall, at
its option, either pay the same in cash or deliver to the holder an additional
number of fully paid and nonassessable shares of Common Stock determined by
dividing the amount of such accrued and unpaid dividends by the Conversion
Price.

     (i) The Corporation shall at all times reserve and keep available out of
its authorized and unissued Common Stock, solely for the purpose of effecting
the conversion of the Series B Convertible Preferred Stock, such number of
shares of Common Stock as shall from time to time be sufficient to effect the
conversion of all then outstanding shares of Series B Convertible Preferred
Stock. The Corporation shall from time to time, in accordance with the laws of
Delaware, increase the authorized amount of Common Stock if at any time the
number of authorized shares of Common Stock remaining unissued shall not be
sufficient to permit the conversion at such time of all then outstanding shares
of Series B Convertible Preferred Stock.

     Section 9.  Reports as to Adjustments.  Whenever the Conversion Price is
                 -------------------------
adjusted as provided in Section 8 hereof, the Corporation shall (i) promptly
place on file at its principal office and at the office of each transfer agent
for the Series B Convertible Preferred Stock, if any, a statement, signed by an
officer of the Corporation, setting forth in reasonable detail the event
requiring the adjustment and the method by which such adjustment was calculated
and specifying the new Conversion Price, and (ii) promptly mail to the holders
of record of the outstanding shares of Series B Convertible Preferred Stock at
their respective addresses as the same shall appear in the Corporation's stock
records a notice stating that the number of shares of Common Stock into which
the shares of Series B Convertible Preferred Stock are convertible has been
adjusted and setting forth the new Conversion Price (or describing the new
stock, securities, cash or other property) as a result of such adjustment, a
brief statement of the facts requiring such adjustment and the computation
thereof, and when such adjustment became effective.

     Section 10.  Definitions.  For the purposes of the Certificate of
                  -----------
Designations, Preferences and Rights of Series B Convertible Redeemable
Preferred Stock which embodies this resolution:

     "Current Market Price" per share of Common Stock on any date for all
purposes of Section 8 shall be deemed to be the closing price per share of
Common Stock on the date

                                       13


specified. For all other purposes hereunder, "Current Market Price" on any date
shall be deemed to be the average of the closing prices per share of Common
Stock for the five (5) consecutive trading days ending two trading days prior to
such date. The closing price for each day shall be the last sale price, regular
way or, in case no such sale takes place on such day, the average of the closing
bid and asked prices, regular way, in either case as reported in the principal
consolidated transaction reporting system with respect to securities listed or
admitted to trading on the New York Stock Exchange or, if the Common Stock is
not listed or admitted to trading on the New York Stock Exchange, as reported in
the principal consolidated transaction reporting system with respect to
securities listed on the principal national securities exchange on which the
Common Stock is listed or admitted to trading or, if the Common Stock is not
listed or admitted to trading on any national securities exchange, the last
quoted sale price or, if not so quoted, the average of the high bid and low
asked prices in the over-the-counter market, as reported by the National
Association of Securities Dealers, Inc. Automated Quotations System ("NASDAQ")
or such other system then in use, or, if on any such date the Common Stock is
not quoted by any such organization, the average of the closing bid and asked
prices as furnished by a professional market maker making a market in the Common
Stock selected by the Board of Directors. If the Common Stock is not publicly
held or so listed or publicly traded, "Current Market Price" shall mean the Fair
Market Value per share as determined in good faith by the Board of Directors of
the Corporation.

     "Fair Market Value" means the amount which a willing buyer would pay a
willing seller in an arm's-length transaction as determined in good faith by the
Board of Directors of the Corporation, unless otherwise provided herein.

     "Person" means any individual, firm, corporation or other entity, and shall
include any successor (by merger or otherwise) of such entity.

     "Trading Day" means a day on which the principal national securities
exchange on which the Common Stock is listed or admitted to trading is open for
the transaction of business or, if the Common Stock is not listed or admitted to
trading on any national securities exchange, any day other than a Saturday,
Sunday, or a day on which banking institutions in the State of New York are
authorized or obligated by law or executive order to close.

     Section 11.  Rank. The Series B Convertible Preferred Stock shall, with
                  ----
respect to payment of dividends, redemption payments and rights upon
liquidation, dissolution or winding up of the Corporation, rank (i) prior to the
Common Stock of the Corporation and any class or series of Preferred Stock which
provides by its terms that it is to rank junior to the Series B Preferred Stock
and (ii) on a parity with each other class or series of Preferred Stock of the
Corporation.

     Section 12.  Alternate Consideration.  For purposes of determining the
                  -----------------------
consideration payable upon exercise of the optional redemption provided in
Section 4(a)(ii) and upon the exercise of the Exchange Right provided in Section
5, if there shall have occurred a Transaction, as defined in Section 8(b)(iii),
the Common Stock that would otherwise have been issued to a holder of Series B
Convertible Preferred Stock for each share of Series B Convertible Preferred
Stock pursuant to Section 4(a)(ii) or Section 5, as applicable, shall be deemed
to instead be the kind and amount of shares of stock or other securities and
property receivable (including cash)

                                       14


upon consummation of such Transaction (the "Alternate Consideration") in respect
of the Common Stock that would result in the Fair Market Value of such Alternate
Consideration, measured as of the Redemption Date or Exchange Date, as
applicable, being equal to (X) if prior to Stockholder Approval, the greater of
(a) the Liquidation Value plus all dividends accrued and unpaid with respect to
such share of Series B Convertible Preferred Stock, whether or not declared,
measured as of the Redemption Date or the Exchange Date, as applicable, and (b)
the Fair Market Value of the kind and amount of shares of stock and other
securities and property receivable (including cash) pursuant to Section
8(b)(iii) which would have been issued if such share of Series B Convertible
Preferred Stock had been converted pursuant to Section 8 immediately prior to
the consummation of the Transaction; or (Y) if after Stockholder Approval, the
Liquidation Value plus all dividends accrued and unpaid with respect to such
share of Series B Convertible Preferred Stock, whether or not declared, measured
as of the Redemption Date or Exchange Date, as applicable. In the event the
subject Transaction provides for an election of the consideration to be received
in respect of the Common Stock, then each holder of Series B Convertible
Preferred Stock shall be entitled to make a similar election with respect to the
Alternate Consideration to be received by it under Section 4(a)(ii) or Section
5, as applicable. Any determination of the Fair Market Value of any Alternate
Consideration (other than cash) shall be determined by an independent investment
banking firm of nationally recognized standing selected by the Board of
Directors of the Corporation. The Fair Market Value of any Alternate
Consideration that is listed on any national securities exchange or traded on
the NASDAQ National Market shall be deemed to be the Current Market Price of
such Alternate Consideration.

     Re:  Acquisition of Litton Industries, Inc.

Ladies and Gentlemen:

     We have acted as counsel to Northrop Grumman Corporation, a Delaware
corporation ("Parent"), in connection with the preparation and execution of
the Amended and Restated Agreement and Plan of Merger dated as of January 23,
2001 (together with all exhibits, annexes and attachments thereto, the "Merger
Agreement"), by and among Litton Industries, Inc., a Delaware corporation (the
"Company"), Parent, NNG, Inc., a Delaware corporation and a wholly owned
subsidiary of Parent ("Holdco") and LII Acquisition I Corp., a Delaware
corporation and a wholly owned subsidiary of Holdco ("Acquisition I"), which
agreement amends, restates and supersedes that certain Agreement and Plan of
Merger, dated as of December 21, 2000, among the Company, Parent and Acquisition
I (the "Original Agreement").  Pursuant to the terms of the Original
Agreement, Acquisition I commenced a tender offer (the "Original Offer") to
purchase for cash (a) all of the outstanding shares of common stock, par value
$1.00 per share, of the Company (the "Litton Common Shares") and (b) all of the
outstanding shares of Series B $2 Cumulative Preferred Stock, par value $5.00
per share, of the Company (the "Litton Preferred Shares"), as described in the
Offer to Purchase for Cash dated January 5, 2001.

     Pursuant to the Merger Agreement, Parent will cause Acquisition to amend
the Original Offer to become an exchange offer by Holdco (the Original Offer as
so amended, the "Offer"), filed on a Registration Statement (Form S-4) with the
Securities and Exchange Commission (the "Registration Statement"), in which each
Litton Common Share accepted by Holdco in accordance with the terms of the Offer
will be exchanged for the right to receive from Holdco, at the election of the
holder of such Share: (X) an amount of cash or (Y) Holdco Common Stock or (Z)
Holdco Preferred Stock, or a combination of such alternatives, subject to
proration in the case of alternatives (Y) and (Z).  The Offer will contain the
same cash offer for the Litton


Northrop Grumman Corporation
February 1, 2001
Page 2

Preferred Shares as was set forth in the Original Offer.  Capitalized terms used
but not defined herein shall have the meaning ascribed to them in the Merger
Agreement.

     The parties to the Merger Agreement have agreed that Acquisition I will be
merged with and into the Company with the Company as the surviving corporation,
as described in Article 2 of the Merger Agreement (the "Litton Merger"), and
Parent has agreed that immediately prior to the Expiration Date of the Offer
pursuant to the Agreement and Plan of Merger attached as Exhibit A to the Merger
Agreement (the "Northrop Merger Agreement") , NGC Acquisition Corp., a
Delaware corporation and wholly owned subsidiary of Holdco ("Acquisition II"),
will be merged with and into Parent with Parent as the surviving corporation
(the "Northrop Merger" and together with the Litton Merger, the "Mergers").
In the Litton Merger, holders of Litton Common Shares outstanding immediately
prior to the Effective Time (other than Litton Common Shares owned by Parent or
any subsidiary or affiliate of Parent or held in the treasury of the Company or
owned by any subsidiary of the Company, which will be canceled pursuant to the
terms of the Merger Agreement) will receive cash in exchange for their Litton
Common Shares.  Each Litton Preferred Share that remains outstanding at the
Effective Time will remain outstanding as a preferred share of the surviving
corporation of the Litton Merger.  Pursuant to the Northrop Merger Agreement,
each share of common stock, par value $1.00 per share, of Parent ("Parent Common
Stock") outstanding at the Effective Time will be converted into one share of
Holdco Common Stock.

     In rendering this opinion, we have reviewed the Merger Agreement (including
the Northrop Merger Agreement), the Registration Statement and such other
documents as we have deemed necessary or appropriate.  We have relied upon the
truth and accuracy at all relevant times of the facts, statements, covenants,
representations and warranties contained in the Merger Agreement, the
Registration Statement, the certificate, dated as of the date hereof (the
"Certificate"), received from Parent and other information provided by Parent.
We have assumed that any representations made in the Certificate or in the
Merger Agreement "to the knowledge of" or similarly qualified will be true,
correct and complete on the closing date of the Offer and the Effective Time of
the Litton Merger without such qualifications.  We have also assumed the
authenticity of original documents submitted to us, the conformity to the
originals of documents submitted to us as copies, and the due and valid
execution and delivery of all such documents where due execution and delivery
are a prerequisite to the effectiveness thereof.

     Based upon the facts and statements set forth above, our examination and
review of the documents referred to above and subject to the assumptions set
forth herein, it is our opinion that for federal income tax purposes:

     (i)  the Northrop Merger will qualify as a "reorganization" within the
          meaning of Section 368(a) of the Internal Revenue Code of 1986, as
          amended (the "Code");


Northrop Grumman Corporation
February 1, 2001
Page 3

     (ii)  with respect to the Northrop Merger, each of Parent, Holdco and
           Acquisition II will be a "party to the reorganization" within the
           meaning of Section 368(b) of the Code;

     (iii) stockholders of Parent will not recognize any gain or loss on the
           exchange of Parent Common Stock for Holdco Common Stock in the
           Northrop Merger;

     (iv)  the exchange of Litton Common Shares for Holdco Common Stock, Holdco
           Preferred Stock and cash pursuant to the Offer, together with the
           Northrop Merger and Litton Merger, will qualify as a transfer of
           property by the Litton shareholders to Holdco described in Section
           351(a) or Section 351(b) of the Code;

     (v)   no gain or loss will be recognized by Parent, Holdco, the Company,
           Acquisition I or Acquisition II as a result of the Offer or the
           Mergers; and

     (vi)  holders of Litton Common Shares who exchange such shares solely for
           Holdco Common Stock or Holdco Preferred Stock will not recognize gain
           or loss;

     It is also our opinion that the discussion under the heading "Material
Federal Income Tax Consequences" in the Registration Statement accurately sets
forth the material federal income tax consequences of the Offer and the Litton
Merger to the Litton stockholders.

     This opinion addresses only the matters described above, and does not
address any other federal, state, local or foreign tax consequences that may
result from the Offer or Mergers or any other transaction undertaken in
connection therewith.  You should be aware that legal opinions are not binding
upon the Internal Revenue Service or the courts, and there can be no assurance
that a contrary position would not be asserted by the Internal Revenue Service
or sustained by the courts.

     This opinion represents our best judgment regarding the application of
federal income tax laws under the Code, existing judicial decisions,
administrative regulations and published rulings and procedures.  No assurance
can be given that future legislative, judicial or administrative changes, on
either a prospective or retroactive basis, would not adversely affect the
accuracy of the conclusions stated herein.  Furthermore, in the event any one of
the statements, representations, or assumptions upon which we have relied to
issue this opinion is incorrect, our opinion might be adversely affected.

     We hereby consent to the filing of this opinion with the Securities and
Exchange Commission as an exhibit to the Registration Statement.  We also
consent to the use of our name under the heading "Material Federal Income Tax
Consequences" in the Offer forming part of the

Registration Statement.  This opinion may not be used for any other purposes and
may not otherwise be disclosed to or relied upon by any other person without our
prior written consent.  This opinion is expressed as of the date hereof and we
disclaim any undertaking to advise you of any subsequent changes in applicable
law after the date hereof.


                                       Very truly yours,

Attention:  Gary W. McKenzie
            Vice President, Tax

Gentlemen:

     You have asked for our opinion regarding certain U.S. Federal income tax
consequences of the events described below under the heading "The Transactions."

     The opinions set forth above are based on the Internal Revenue Code of
1986, as amended (the "Code"), the Regulations, judicial decisions and
administrative rulings and other pronouncements, all as in effect on the date of
this letter.

                                     Facts
                                     -----

The Parties and the Merger Agreement
- ------------------------------------

     This opinion relates to the transactions to be consummated pursuant to the
Amended and Restated Agreement and Plan of Merger, dated as of January 23, 2001,
by and among the following parties:

  .  Litton Industries, Inc. ("Company"), a Delaware corporation. As of December
     31, 2000, the issued and outstanding stock of Company consisted of Series B
     $2 Cumulative Preferred Stock ("Company Preferred Stock") and common stock
     ("Company Common Stock"). Both the Company Common Stock and the Company
     Preferred Stock are widely held and publicly traded. Unitrin, Inc., a
     Delaware corporation owns (directly and through subsidiaries) approximately
     27.8% of the Company Common Stock.

  .  Northrop Grumman Corporation, a Delaware corporation ("Parent"). The issued
     and outstanding stock of Parent consists of common stock ("Parent Common
     Stock"), which is widely held and publicly traded.


Northrop Grumman Corporation
February 1, 2001

  .  NNG, Inc, a Delaware corporation and wholly-owned subsidiary of Parent
     ("Holdco").

  .  LII Acquisition Corp., a Delaware corporation and wholly-owned subsidiary
     of Holdco ("Acquisition I").

  .  NGC Acquisition Corp., a Delaware corporation and wholly-owned subsidiary
     of Holdco ("Acquisition II"). /1/

The Amended and Restated Agreement and Plan of Merger, together with the Annex,
Exhibits and attachments thereto, is referred to in this opinion as the "Merger
Agreement." Except as otherwise indicated, the defined terms used in the Merger
Agreement are used in this opinion.

Materials Relied Upon
- ---------------------

     In rendering this opinion, we have reviewed the Merger Agreement, the
Stockholder's Agreement, the Registration Rights Agreement and the Form S-4 and
other materials submitted to the shareholders of Company and Parent and filed
with the U.S. Securities and Exchange Commission (collectively, the
"Registration Statement"), all as provided by you. Although we have reviewed
these materials, we have not verified independently the facts upon which our
conclusions are based. Any changes in the facts could affect our conclusions.

     Our conclusions are also based on Parent's representations provided to us.
We assume that Parent's representations are also representations of Holdco.

The Transactions
- ----------------

     Pursuant to the Merger Agreement, Holdco intends to acquire Company and
Parent through the following transactions:

  1. The Offer. Holdco will amend its cash tender offer for Company stock to an
     ---------
     exchange offer (the "Offer"). In the offer as so amended,

     a. Holders of Company Preferred Stock accepting such offer will transfer
        their shares of Company Preferred Stock to Acquisition I for $35 cash
        per share.


- --------------
/1/  Acquisition II is not a party to the Merger Agreement, but, together with
     Parent and Holdco, is a party to the Northrop Merger Agreement, attached
     thereto as Exhibit A.


Northrop Grumman Corporation
February 1, 2001
Page 3

     b. Holders of Company Common Stock accepting such offer will transfer their
        shares of Company Common Stock to Holdco in exchange for a right to
        receive, per share, at their election, $80 cash, Holdco Common Stock or
        Holdco Preferred Stock, or a combination thereof./2/ Elections to
        receive cash will not be subject to proration. Holdco Common Stock
        Elections and Holdco Preferred Stock Elections will be subject to
        proration as between Holdco Common Stock and Holdco Preferred Stock, if
        either is over-subscribed. Cash will be paid in lieu of fractional
        shares of Holdco Common Stock or Holdco Preferred Stock.

  2. The Litton Merger. Subsequent to the Offer, Acquisition I will merge with
     -----------------
     and into Company (the "Litton Merger"). In the Litton Merger:

     a. Acquisition I will be merged with and into Company with Company as the
        survivor.

     b. Each outstanding share of Company Common Stock will be converted into a
        right to receive $80 cash per share.

     c. Each share of Acquisition I stock outstanding (all of which will be held
        by Holdco) will be converted into one share of Company Common Stock.

     At the conclusion of the Litton Merger, Holdco will own all the issued and
     outstanding Company Common Stock and any of the Company Preferred Stock
     that is submitted to Acquisition I in the Offer.

  3. The Northrop Merger. Immediately prior to the Expiration Date of the Offer,
     -------------------
     Acquisition II will merge with and into Parent (the "Northrop Merger"). In
     the Northrop Merger:

     a. Acquisition II will be merged with and into Parent with Parent as the
        survivor.

     b. Each share of Parent stock outstanding will be converted into one share
        of Holdco Common Stock.

- ------------
/2/  Each share of Company Common Stock that is exchanged for Holdco Common
     Stock will be exchanged for a number of shares of the Holdco Common Stock
     equal to the quotient of $80.25 divided by the average of the closing
     prices for Parent Common Stock as reported on the New York Stock Exchange
     Composite Transaction Reporting System for the five consecutive trading
     days ending on the second trading day before the final expiration date of
     the Offer.

     Each share of Company Common Stock that is exchanged for Holdco Preferred
     Stock will be exchanged for 0.8025 of a share of the Holdco Preferred
     Stock.


Northrop Grumman Corporation
February 1, 2001
Page 4


     c. Each share of Acquisition II stock outstanding (all of which will be
        held by Holdco) will be converted into one share of common stock of
        Parent).

     At the conclusion of the Northrop Merger, Holdco will own all the issued
     and outstanding common stock of Parent.

                                  Conclusions

     Based on the facts and representations set forth above, it is our opinion
that:

  1. The Northrop Merger will qualify as a "reorganization" within the meaning
     of section 368(a) of the Code.

  2. With respect to the Northrop Merger, Parent, Holdco and Acquisition II will
     each be a "party to the reorganization" within the meaning of section
     368(b) of the Code.

  3. Under section 354(a) of the Code, no gain or loss will be recognized to the
     Parent shareholders upon the receipt of Holdco Common Stock in the Northrop
     Merger.

  4. Under section 1032(a) of the Code, no gain or loss will be recognized to
     Holdco in the Northrop Merger.

  5. Under section 361(a) of the Code, no gain or loss will be recognized to
     Acquisition II in the Northrop Merger.

  6. No gain or loss will be recognized by Parent in the Northrop Merger.

  7. For Federal income tax purposes, (a) the formation of Acquisition I and the
     merger of Acquisition I into Company will be disregarded, and (b) such
     transactions will be treated as transfers by the Company shareholders of
     their Company Common Stock to Holdco in exchange for cash, Holdco Common
     Stock, Holdco Preferred Stock, or some combination thereof, as the case may
     be.

  8. The Offer and the Northrop Merger will qualify as an exchange of property
     by the Company shareholders and the Parent shareholders to Holdco, a
     controlled corporation, within the meaning of section 351 of the Code.

  9. No gain or loss will be recognized to holders of Company Common stock who
     exchange such stock solely for Holdco Common Stock or Holdco Preferred
     Stock.


Northrop Grumman Corporation
February 1, 2001
Page 5

  10. No gain or loss will be recognized to Parent, Holdco, Company, Acquisition
      I or Acquisition II in the Offer and the Northrop Merger.

     It is also our opinion that the discussion under the heading "Material
Federal Income Tax Consequences" in the Registration Statement accurately sets
forth the material federal income tax consequences of Offer and the Litton
Merger to the Litton stockholders.

                                 Miscellaneous

     This letter addresses only certain Federal income tax consequences of the

                                Ivins, Phillips & Barker



                                                                    EXHIBIT 10.3

                                    FORM OF
                    CHANGE OF CONTROL EMPLOYMENT AGREEMENT

     AGREEMENT by and between Litton Industries, Inc., a Delaware corporation
(the "Company") and ____________________ (the "Executive"), dated as of the
_____ day of __________, _____.

     The Board of Directors of the Company (the "Board") has determined that it
is in the best interests of the Company and its shareholders to assure that the
Company will have the continued dedication of the Executive, notwithstanding the
possibility, threat or occurrence of a Change of Control (as defined below) of
the Company.  The Board believes it is imperative to diminish the inevitable
distraction of the Executive by virtue of the personal uncertainties and risks
created by a pending or threatened Change of Control and to encourage the
Executive's full attention and dedication to the Company currently and in the
event of any threatened or pending Change of Control, and to provide the
Executive with compensation and benefits arrangements upon a Change of Control
which ensure that the compensation and benefits expectations of the Executive
will be satisfied and which are competitive with those of other corporations.
Therefore, in order to accomplish these objectives, the Board has caused the
Company to enter into this Agreement.

     NOW, THEREFORE, IT IS HEREBY AGREED AS FOLLOWS:

     1.   Certain Definitions.
          -------------------

          (a) The "Effective Date" shall mean the first date during the Change
of Control Period (as defined in Section 1(b)) on which a Change of Control (as
defined in Section 2) occurs.  Anything in this Agreement to the contrary
notwithstanding, if a Change of Control occurs and if the Executive's employment
with the Company is terminated prior to the date on which the Change of Control
occurs, and if it is reasonably demonstrated by the Executive that such
termination of employment (i) was at the request of a third party who has taken
steps reasonably calculated to effect a Change of Control or (ii) otherwise
arose in connection with or anticipation of a Change of Control, then for all
purposes of this Agreement the "Effective Date" shall mean the date immediately
prior to the date of such termination of employment.

           (b) The "Change of Control Period" shall mean the period commencing
on the date hereof and ending on the third anniversary of the date hereof;
provided, however, that commencing on the date one year after the date hereof,
- --------  -------
and on each annual anniversary of such date (such date and each annual
anniversary thereof shall be hereinafter referred to as the "Renewal Date"),
unless previously terminated, the Change of Control Period shall be
automatically extended so as to terminate three years from such Renewal Date,
unless at least 60 days prior to the Renewal Date the Company shall give notice
to the Executive that the Change of Control Period shall not be so extended.


     2.   Change of Control.  For the purpose of this Agreement, a "Change of
          -----------------
Control" shall mean:

          (a) The acquisition by any individual, entity or group (within the
meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934,
as amended (the "Exchange Act")) (a "Person") of beneficial ownership (within
the meaning of Rule 13d-3 promulgated under the Exchange Act) of 30% or more of
either (i) the then outstanding shares of common stock of the Company (the
"Outstanding Company Common Stock") or (ii) the combined voting power of the
then outstanding voting securities of the Company entitled to vote generally in
the election of directors (the "Outstanding Company Voting Securities");
provided, however, that for purposes of this subsection (a), the following
- --------  -------
acquisitions of stock shall not constitute a Change of Control:  (i) any
acquisition directly from the Company, (ii) any acquisition by the Company,
(iii) any acquisition by any employee benefit plan (or related trust) sponsored
or maintained by the Company or any corporation controlled by the Company or
(iv) any acquisition by any corporation pursuant to a transaction which complies
with clauses (i), (ii) and (iii) of subsection (c) of this Section 2; or

          (b) Individuals who, as of the date hereof, constitute the Board (the
"Incumbent Board") cease for any reason to constitute at least a majority of the
Board; provided, however, that any individual becoming a director subsequent to
       --------  -------
the date hereof whose election, or nomination for election by the Company's
shareholders, was approved by a vote of at least a majority of the directors
then comprising the Incumbent Board shall be considered as though such
individual were a member of the Incumbent Board, but excluding, for this
purpose, any such individual whose initial assumption of office occurs as a
result of an actual or threatened election contest with respect to the election
or removal of directors or other actual or threatened solicitation of proxies or
consents by or on behalf of a Person other than the Board; or

          (c) Consummation of a reorganization, merger or consolidation or sale
or other disposition of all or substantially all of the assets of the Company (a
"Business Combination"), in each case, unless, following such Business
Combination, (i) all or substantially all of the individuals and entities who
were the beneficial owners, respectively, of the Outstanding Company Common
Stock and Outstanding Company Voting Securities immediately prior to such
Business Combination beneficially own, directly or indirectly, more than 60% of,
respectively, the then outstanding shares of common stock and the combined
voting power of the then outstanding voting securities entitled to vote
generally in the election of directors, as the case may be, of the corporation
resulting from such Business Combination (including, without limitation, a
corporation which as a result of such transaction owns the Company or all or
substantially all of the Company's assets either directly or through one or more
subsidiaries) in substantially the same proportions as their ownership,
immediately prior to such Business Combination of the Outstanding Company Common
Stock and Outstanding Company Voting Securities, as the case may be, (ii) no
Person (excluding any employee benefit plan (or related trust) of the Company or
such corporation resulting from such Business Combination) beneficially owns,
directly or indirectly, 30% or more of, respectively, the then outstanding
shares of common stock of the corporation resulting from such Business
Combination or the combined voting power of the then outstanding voting
securities of such corporation except to the extent that such ownership existed
prior to the Business Combination, and (iii) at least a majority of the members
of the board of directors of the corporation resulting

                                       2


from such Business Combination were members of the Incumbent Board at the time
of the execution of the initial agreement, or of the action of the Board,
providing for such Business Combination; or

         (d) Approval by the shareholders of the Company of a complete
liquidation or dissolution of the Company.

     3.  Employment Period.  The Company hereby agrees to continue the Executive
         -----------------
in its employ, and the Executive hereby agrees to remain in the employ of the
Company subject to the terms and conditions of this Agreement, for the period
commencing on the Effective Date and ending on the third anniversary of such
date (the "Employment Period").

     4.  Terms of Employment.
         -------------------

         (a)  Position and Duties.
              -------------------

              (i)  During the Employment Period, (A) the Executive's position
(including status, offices, titles and reporting requirements), authority,
duties and responsibilities shall be at least commensurate in all material
respects with the most significant of those held, exercised and assigned at any
time during the 120-day period immediately preceding the Effective Date and (B)
the Executive's services shall be performed at the location where the Executive
was employed immediately preceding the Effective Date or any office or location
less than 35 miles from such location.

              (ii) During the Employment Period, and excluding any periods of
vacation and sick leave to which the Executive is entitled, the Executive agrees
to devote reasonable attention and time during normal business hours to the
business and affairs of the Company and, to the extent necessary to discharge
the responsibilities assigned to the Executive hereunder, to use the Executive's
reasonable best efforts to perform faithfully and efficiently such
responsibilities.  During the Employment Period it shall not be a violation of
this Agreement for the Executive to (A) serve on corporate, civic or charitable
boards or committees, (B) deliver lectures, fulfill speaking engagements or
teach at educational institutions and (C) manage personal investments, so long
as such activities do not significantly interfere with the performance of the
Executive's responsibilities as an employee of the Company in accordance with
this Agreement.  It is expressly understood and agreed that to the extent that
any such activities have been conducted by the Executive prior to the Effective
Date, the continued conduct of such activities (or the conduct of activities
similar in nature and scope thereto) subsequent to the Effective Date shall not
thereafter be deemed to interfere with the performance of the Executive's
responsibilities to the Company.

         (b)  Compensation.
              ------------

              (i)  Base Salary. During the Employment Period, the Executive
                   -----------
shall receive an annual base salary ("Annual Base Salary"), which shall be paid
at a monthly rate, at least equal to twelve times the highest monthly base
salary paid or payable, including any base salary which has been earned but
deferred, to the Executive by the Company and its affiliated companies in
respect of the twelve-month period immediately preceding the month in which the
Effective Date occurs. During the Employment Period, the Annual Base Salary
shall be
                                       3


reviewed no more than 12 months after the last salary increase awarded to the
Executive prior to the Effective Date and thereafter at least annually. Any
increase in Annual Base Salary shall not serve to limit or reduce any other
obligation to the Executive under this Agreement. Annual Base Salary shall not
be reduced after any such increase and the term Annual Base Salary as utilized
in this Agreement shall refer to Annual Base Salary as so increased. As used in
this Agreement, the term "affiliated companies" shall include any company
controlled by, controlling or under common control with the Company.

          (ii)  Annual Bonus.  In addition to Annual Base Salary, the Executive
                ------------
shall be awarded, for each fiscal year ending during the Employment Period, an
annual bonus in cash at least equal to the Executive's highest award under the
Company's Performance Award Plan(s), or any comparable bonus under any
predecessor or successor plan, for the last three full fiscal years prior to the
Effective Date (any such award shall be annualized for any fiscal year in the
event that the Executive was not employed by the Company for the whole of such
fiscal year) (the "Annual Bonus").  Each such Annual Bonus plus unpaid but due
amounts from prior awards shall be paid in accordance with the terms of the
Performance Award Plan or successor plan, but in no event later than such amount
would have been paid under the Performance Award Plan.  Any portion of an award
made under the Performance Award Plan, or any comparable or successor plan,
shall be paid on the last day of the Employment Period to the extent not
previously paid but only if the Executive is employed on such date.

          (iii) Incentive, Savings and Retirement Plans.  During the Employment
                ---------------------------------------
Period, the Executive shall be entitled to participate in all incentive
(including stock option or similar incentive plans), savings and retirement
plans, practices, policies and programs applicable generally to other peer
executives of the Company and its affiliated companies, but in no event shall
such plans, practices, policies and programs provide the Executive with
incentive opportunities (measured with respect to both regular and special
incentive opportunities, to the extent, if any, that such distinction is
applicable), savings opportunities and retirement benefit opportunities, in each
case, less favorable, in the aggregate, than the most favorable of those
provided by the Company and its affiliated companies for the Executive under
such plans, practices, policies and programs as in effect at any time during the
120-day period immediately preceding the Effective Date or if more favorable to
the Executive, those provided generally at any time after the Effective Date to
other peer executives of the Company and its affiliated companies.

          (iv)  Welfare Benefit Plans.  During the Employment Period, the
                ---------------------
Executive and/or the Executive's family, as the case may be, shall be eligible
for participation in and shall receive all benefits under welfare benefit plans,
practices, policies and programs provided by the Company and its affiliated
companies (including, without limitation, medical, prescription, dental,
disability, salary continuance, employee life, group life, accidental death and
travel accident insurance plans and programs) to the extent applicable generally
to other peer executives of the Company and its affiliated companies, but in no
event shall such plans, practices, policies and programs provide the Executive
with benefits which are less favorable, in the aggregate, than the most
favorable of such plans, practices, policies and programs in effect for the
Executive at any time during the 120-day period immediately preceding the
Effective Date or, if more favorable to the Executive, those provided generally
at any time after the Effective Date to other peer executives of the Company and
its affiliated companies.

                                       4


          (v)     Expenses. During the Employment Period, the Executive shall be
                  --------
entitled to receive prompt reimbursement for all reasonable expenses incurred by
the Executive in accordance with the most favorable policies, practices and
procedures of the company and its affiliated companies in effect for the
Executive at any time during the 120-day period immediately preceding the
Effective Date or, if more favorable to the Executive, as in effect generally at
any time thereafter with respect to other peer executives of the Company and its
affiliated companies.

          (vi)    Fringe Benefits.  During the Employment Period, the Executive
                  ---------------
shall he entitled to fringe benefits, including, without limitation, if
applicable, tax and financial planning services, use of an automobile and
payment of related expenses, in accordance with the most favorable plans,
practices, programs and policies of the company and its affiliated companies in
effect for the Executive at any time during the 120-day period immediately
preceding the Effective Date or, if more favorable to the Executive, as in
effect generally at any time thereafter with respect to other peer executives of
the Company and its affiliated companies.

          (vii)   Office and Support Staff.  During the Employment Period, the
                  ------------------------
Executive shall be entitled to an office or offices of a size and with
furnishings and other appointments, and to exclusive personal secretarial and
other assistance, at least equal to the most favorable of the foregoing provided
to the Executive by the company and its affiliated companies at any time during
the 120-day period immediately preceding the Effective Date or, if more
favorable to the Executive, as provided generally at any time thereafter with
respect to other peer executives of the company and its affiliated companies.

          (viii)  Vacation.  During the Employment Period, the Executive shall
                  --------
be entitled to paid vacation in accordance with the most favorable plans,
policies, programs and practices of the Company and its affiliated companies as
in effect for the Executive at any time during the 120-day period immediately
preceding the Effective Date or, if more favorable to the Executive, as in
effect generally at any time thereafter with respect to other peer executives of
the Company and its affiliated companies.

     5.   Termination of Employment.
          -------------------------

          (a) Death or Disability.  The Executive's employment shall terminate
              -------------------
automatically upon the Executive's death during the Employment Period.  If the
Company determines in good faith that the Disability of the Executive has
occurred during the Employment Period (pursuant to the definition of Disability
set forth below), it may give to the Executive written notice in accordance with
Section 12(b) of this Agreement of its intention to terminate the Executive's
employment.  In such event, the Executive's employment with the Company shall
terminate effective on the 30th day after receipt of such notice by the
Executive (the "Disability Effective Date"); provided that, within the 30 days
                                             --------
after such receipt, the Executive shall not have returned to full-time
performance of the Executive's duties.  For purposes of this Agreement,
"Disability" shall mean the absence of the Executive from the Executive's duties
with the Company on a full-time basis for 180 consecutive business days as a
result of incapacity due to mental or physical illness which is determined to be
total and permanent by a physician selected by the Company or its insurers and
acceptable to the Executive or the Executive's legal representative.

                                       5


          (b) Cause.  The Company may terminate the Executive's employment
              -----
during the Employment Period for Cause.  For purposes of this Agreement, "Cause"
shall mean:

              (i)  the willful and continued failure of the Executive to perform
     substantially the Executive's duties with the Company or one of its
     affiliates (other than any such failure resulting from incapacity due to
     physical or mental illness), after a written demand for substantial
     performance is delivered to the Executive by the Board or the Chief
     Executive Officer of the Company which specifically identifies the manner
     in which the Board or Chief Executive Officer believes that the Executive
     has not substantially performed the Executive's duties, or

              (ii) the willful engaging by the Executive in illegal conduct or
     gross misconduct which is materially and demonstrably injurious to the
     Company.

For purposes of this provision, no act or failure to act, on the part of the
Executive, shall be considered "willful" unless it is done, or omitted to be
done, by the Executive in bad faith or without reasonable belief that the
Executive's action or omission was in the best interests of the Company.  Any
act, or failure to act, based upon authority given pursuant to a resolution duly
adopted by the Board or upon the instructions of the Chief Executive Officer or
a senior officer of the Company or based upon the advice of counsel for the
Company shall be conclusively presumed to be done, or omitted to be done, by the
Executive in good faith and in the best interests of the Company.  The cessation
of employment of the Executive shall not be deemed to be for Cause unless and
until there shall have been delivered to the Executive a copy of a resolution
duly adopted by the affirmative vote of not less than three-quarters of the
entire membership of the Board at a meeting of the Board called and held for
such purpose (after reasonable notice is provided to the Executive and the
Executive is given an opportunity, together with counsel, to be heard before the
Board), finding that, in the good faith opinion of the Board, the Executive is
guilty of the conduct described in subparagraph (i) or (ii) above, and
specifying the particulars thereof in detail.

          (c) Good Reason.  The Executive's employment may be terminated by the
              -----------
Executive for Good Reason.  For purposes of this Agreement, "Good Reason" shall
mean:

              (i)  the assignment to the Executive of any duties inconsistent in
     any respect with the Executive's position (including status, offices,
     titles and reporting requirements), authority, duties or responsibilities
     as contemplated by Section 4(a) of this Agreement, or any other action by
     the Company which results in a diminution in such position, authority,
     duties or responsibilities, excluding for this purpose an isolated,
     insubstantial and inadvertent action not taken in bad faith and which is
     remedied by the Company promptly after receipt of notice thereof given by
     the Executive;

              (ii) any failure by the Company to comply with any of the
     provisions of Section 4(b) of this Agreement, other than an isolated,
     insubstantial and inadvertent failure not occurring in bad faith and which
     is remedied by the Company promptly after receipt of notice thereof given
     by the Executive;

                                       6


              (iii) the Company's requiring the Executive to be based at any
     office or location other than as provided in Section 4(a)(i)(B) hereof or
     the Company's requiring the Executive to travel on Company business to a
     substantially greater extent than required immediately prior to the
     Effective Date;

              (iv)  any purported termination by the Company of the Executive's
     employment otherwise than as expressly permitted by this Agreement; or

              (v)   any failure by the Company to comply with and satisfy
     Section 11(c) of this Agreement.

For purposes of this Section 5(c), any good faith determination of "Good Reason"
made by the Executive shall be conclusive.  Anything in this Agreement to the
contrary notwithstanding, a termination by the Executive for any reason during
the 30-day period immediately following the first anniversary of the Effective
Date shall be deemed to be a termination for Good Reason for all purposes of
this Agreement.

          (d) Notice of Termination.  Any termination by the Company for Cause,
              ---------------------
or by the Executive for Good Reason, shall be communicated by Notice of
Termination to the other party hereto given in accordance with Section 12(b) of
this Agreement.  For purposes of this Agreement, a "Notice of Termination" means
a written notice which (i) indicates the specific termination provision in this
Agreement relied upon, (ii) to the extent applicable, sets forth in reasonable
detail the facts and circumstances claimed to provide a basis for termination of
the Executive's employment under the provision so indicated and (iii) if the
Date of Termination (as defined below) is other than the date of receipt of such
notice, specifies the termination date (which date shall be not more than thirty
days after the giving of such notice).  The failure by the Executive or the
Company to set forth in the Notice of Termination any fact or circumstance which
contributes to a showing of Good Reason or Cause shall not waive any right of
the Executive or the Company, respectively, hereunder or preclude the Executive
or the Company, respectively, from asserting such fact or circumstance in
enforcing the Executive's or the Company's rights hereunder.

          (e) Date of Termination.  "Date of Termination" means (i) if the
              -------------------
Executive's employment is terminated by the Company for Cause, or by the
Executive for Good Reason, the date of receipt of the Notice of Termination or
any later date specified therein, as the case may be, (ii) if the Executive's
employment is terminated by the Company other than for Cause or Disability, the
Date of Termination shall be the date on which the Company notifies the
Executive of such termination and (iii) if the Executive's employment is
terminated by reason of death or Disability, the Date of Termination shall be
the date of death of the Executive or the Disability Effective Date, as the case
may be.

     6.   Obligations of the Company Upon Termination.
          -------------------------------------------

          (a) Good Reason; Other Than for Cause, Death or Disability.  If,
              ------------------------------------------------------
during the Employment Period, the Company shall terminate the Executive's
employment other than for Cause or Disability or the Executive shall terminate
employment for Good Reason:

                                       7


               (i)  the Company shall pay to the Executive in a lump sum in cash
     within 30 days after the Date of Termination the aggregate of the following
     amounts:

                    A.  the sum of (1) the Executive's Annual Base Salary
          through the Date of Termination to the extent not theretofore paid,
          (2) the product of (x) the Annual Bonus, and (y) a fraction, the
          numerator of which is the number of days in the current fiscal year
          through the Date of Termination, and the denominator of which is 365
          and (3) any compensation previously deferred by the Executive
          (together with any accrued interest or earnings thereon), any awards
          under the Performance Award Plan or any comparable or successor plan
          and any accrued vacation pay, in each case to the extent not
          theretofore paid (the sum of the amounts described in clauses (1),
          (2), and (3) shall be hereinafter referred to as the "Accrued
          Obligations"); and

                    B.  the amount equal to the product of (1) three and (2) the
          sum of (x) the Executive's Annual Base Salary and (y) the Annual
          Bonus, or if higher, any bonus paid with respect to any fiscal year
          during the Employment Period; and

                    C.  utilizing actuarial assumptions no less favorable to the
          Executive than those in effect immediately prior to the Effective
          Date, an amount equal to the difference between (a) the actuarial
          equivalent of the benefit under the Company's qualified defined
          benefit retirement plan (the "Retirement Plan") and any excess or
          supplemental retirement plan in which the Executive participates
          (together, the "SERP") which the Executive would receive if the
          Executive's employment continued for three years after the Date of
          Termination assuming for this purpose that all accrued benefits are
          fully vested, and, assuming that the Executive's compensation in each
          of the three years is that required by Section 4(b)(i) and Section
          4(b)(ii), over (b) the actuarial equivalent of the Executive's actual
          benefit (paid or payable), if any, under the Retirement Plan and the
          SERP as of the Date of Termination;

               (ii) for three years after the Executive's Date of Termination,
     or such longer period as may be provided by the terms of the appropriate
     plan, practice, policy or program, the Company shall continue benefits to
     the Executive and/or the Executive's family at least equal to those which
     would have been provided to them in accordance with the plans, programs,
     practices and policies described in Section 4(b)(iv) of this Agreement if
     the Executive's employment had not been terminated or, if more favorable to
     the Executive, as in effect generally at any time thereafter with respect
     to other peer executives of the Company and its affiliated companies and
     their families; provided, however, that if the Executive becomes reemployed
                     --------  -------
     with another employer and is eligible to receive medical or other welfare
     benefits under another employer provided plan, the medical and other
     welfare benefits described herein shall be secondary to those provided
     under such other plan during such applicable period of eligibility.  For
     purposes of determining eligibility (but not the time of commencement of
     benefits) of the Executive for retiree benefits pursuant to such plans,
     practices, programs and policies, the Executive shall be considered to have
     remained employed until three years after the Date of Termination and to
     have retired on the last day of such period;

                                       8


               (iii) the Company shall, at its sole expense as incurred,
     provide the Executive with outplacement services the scope and provider of
     which shall be selected by the Executive in his or her sole discretion; and

               (iv)  to the extent not theretofore paid or provided, the Company
     shall timely pay or provide to the Executive any other amounts or benefits
     required to be paid or provided or which the Executive is eligible to
     receive under any plan, program, policy or practice or contract or
     agreement of the Company and its affiliated companies (such other amounts
     and benefits shall be hereinafter referred to as the "Other Benefits").

          (b)  Death.  If the Executive's employment is terminated by reason of
               -----
the Executive's death during the Employment Period, this Agreement shall
terminate without further obligations to the Executive's legal representatives
under this Agreement, other than for payment of Accrued Obligations and the
timely payment or provision of Other Benefits.  Accrued Obligations shall be
paid to the Executive's estate or beneficiary, as applicable, in a lump sum in
cash within 30 days of the Date of Termination.  With respect to the provision
of Other Benefits, the term Other Benefits as utilized in this Section 6(b)
shall include, without limitation, and the Executive's estate and/or
beneficiaries shall be entitled to receive, benefits at least equal to the most
favorable benefits provided by the Company and affiliated companies to the
estates and beneficiaries of peer executives of the Company and such affiliated
companies under such plans, programs, practices and policies relating to death
benefits, if any, as in effect with respect to other peer executives and their
beneficiaries at any time during the 120-day period immediately preceding the
Effective Date or, if more favorable to the Executive's estate and/or the
Executive's beneficiaries, as in effect on the date of the Executive's death
with respect to other peer executives of the Company and its affiliated
companies and their beneficiaries.

          (c)  Disability.  If the Executive's employment is terminated by
               ----------
reason of the Executive's Disability during the Employment Period, this
Agreement shall terminate without further obligations to the Executive, other
than for payment of Accrued Obligations and the timely payment or provision of
Other Benefits. Accrued Obligations shall be paid to the Executive in a lump sum
in cash within 30 days of the Date of Termination. With respect to the provision
of Other Benefits, the term Other Benefits as utilized in this Section 6(c)
shall include, and the Executive shall be entitled after the Disability
Effective Date to receive, disability and other benefits at least equal to the
most favorable of those generally provided by the Company and its affiliated
companies to disabled executives and/or their families in accordance with such
plans, programs, practices and policies relating to disability, if any, as in
effect generally with respect to other peer executives and their families at any
time during the 120-day period immediately preceding the Effective Date or, if
more favorable to the Executive and/or the Executive's family, as in effect at
any time thereafter generally with respect to other peer executives of the
Company and its affiliated companies and their families.

           (d) Cause; Other than for Good Reason.  If the Executive's employment
               ---------------------------------
shall be terminated for Cause during the Employment Period or if the Executive
voluntarily terminates employment during the Employment Period, excluding a
termination for Good Reason, this Agreement shall terminate without further
obligations to the Executive other than the obligation to pay to the Executive
(x) his or her Annual Base Salary through the Date of Termination, (y) the
amount of any compensation previously deferred by the Executive, and (z) Other

                                       9


Benefits, in each case to the extent theretofore unpaid.  In such case, all
Accrued Obligations shall be paid to the Executive in a lump sum in cash within
30 days of the Date of Termination.

     7.  Non-Exclusivity of Rights.  Nothing in this Agreement shall prevent or
         -------------------------
limit the Executive's continuing or future participation in any plan, practice,
policy or program provided by the Company or any of its affiliated companies and
for which the Executive may qualify, nor, subject to Section 12(f), shall
anything herein limit or otherwise affect such rights as the Executive may have
under any contract or agreement with the Company or any of its affiliated
companies.  Amounts which are vested benefits or which the Executive is
otherwise entitled to receive under any plan, policy, practice or program of or
any contract or agreement with the Company or any of its affiliated companies at
or subsequent to the Date of Termination shall be payable in accordance with
such plan, practice, policy or program or contract or agreement except as
explicitly modified by this Agreement.

     8.  Full Settlement.  The Company's obligation to make the payments
         ---------------
provided for in this Agreement and otherwise to perform its obligations
hereunder shall not be affected by any set-off, counterclaim, recoupment,
defense or other claim, right or action which the Company may have against the
Executive or others.  In no event shall the Executive be obligated to seek other
employment or take any other action by way of mitigation of the amounts payable
to the Executive under any of the provisions of this Agreement and such amounts
shall not be reduced whether or not the Executive obtains other employment.  The
Company agrees to pay as incurred, to the full extent permitted by law, all
legal fees and expenses which the Executive may reasonably incur as a result of
any contest (regardless of the outcome thereof) by the Company, the Executive or
others of the validity or enforceability of, or liability under, any provision
of this Agreement or any guarantee of performance thereof (including as a result
of any contest by the Executive about the amount of any payment pursuant to this
Agreement), plus in each case interest on any delayed payment at the applicable
Federal rate provided for in Section 7872(f)(2)(A) of the Internal Revenue Code
of 1986, as amended (the "Code").

     9.  Certain Additional Payments by the Company.
         ------------------------------------------

         (a) Anything in this Agreement to the contrary notwithstanding and
except as set forth below, in the event it shall be determined that any payment
or distribution by the Company to or for the benefit of the Executive (whether
paid or payable or distributed or distributable pursuant to the terms of this
Agreement or otherwise, but determined without regard to any additional payments
required under this Section 9) (a "Payment") would be subject to the excise tax
imposed by Section 4999 of the Code or any interest or penalties are incurred by
the Executive with respect to such excise tax (such excise tax, together with
any such interest and penalties, are hereinafter collectively referred to as the
"Excise Tax"), then the Executive shall be entitled to receive an additional
payment (a "Gross-Up Payment") in an amount such that after payment by the
Executive of all taxes (including any interest or penalties imposed with respect
to such taxes), including, without limitation, any income taxes (and any
interest and penalties imposed with respect thereto) and Excise Tax imposed upon
the Gross-Up Payment, the Executive retains an amount of the Gross-Up Payment
equal to the Excise Tax imposed upon the Payments.

                                       10


          (b) Subject to the provisions of Section 9(c), all determinations
required to be made under this Section 9, including whether and when a Gross-Up
Payment is required and the amount of such Gross-Up Payment and the assumptions
to be utilized in arriving at such determination, shall be made by Deloitte &
Touche or such other certified public accounting firm as may be designated by
the Executive (the "Accounting Firm") which shall provide detailed supporting
calculations both to the Company and the Executive within 15 business days of
the receipt of notice from the Executive that there has been a Payment, or such
earlier time as is requested by the Company.  In the event that the Accounting
Firm is serving as accountant or auditor for the individual, entity or group
effecting the Change of Control, the Executive shall appoint another nationally
recognized accounting firm to make the determinations required hereunder (which
accounting firm shall then be referred to as the Accounting Firm hereunder) All
fees and expenses of the Accounting Firm shall be borne solely by the Company.
Any Gross-Up Payment, as determined pursuant to this Section 9, shall be paid by
the Company to the Executive within five days of the receipt of the Accounting
Firm's determination.  Any determination by the Accounting Firm shall be binding
upon the Company and the Executive.  As a result of the uncertainty in the
application of Section 4999 of the Code at the time of the initial determination
by the Accounting Firm hereunder, it is possible that Gross-Up Payments which
will not have been made by the Company should have been made ("Underpayment"),
consistent with the calculations required to be made hereunder.  In the event
that the Company exhausts its remedies pursuant to Section 9(c) and the
Executive thereafter is required to make a payment of any Excise Tax, the
Accounting Firm shall determine the amount of the Underpayment that has occurred
and any such Underpayment shall be promptly paid by the Company to or for the
benefit of the Executive.

          (c) The Executive shall notify the Company in writing of any claim by
the Internal Revenue Service that, if successful, would require the payment by
the Company of the Gross-Up Payment.  Such notification shall be given as soon
as practicable but no later than ten business days after the Executive is
informed in writing of such claim and shall apprise the Company of the nature of
such claim and the date on which such claim is requested to be paid.  The
Executive shall not pay such claim prior to the expiration of the 30-day period
following the date on which it gives such notice to the Company (or such shorter
period ending on the date that any payment of taxes with respect to such claim
is due).  If the Company notifies the Executive in writing prior to the
expiration of such period that it desires to contest such claim, the Executive
shall:

              (i)   give the Company any information reasonably requested by the
     Company relating to such claim,

              (ii)  take such action in connection with contesting such claim as
     the Company shall reasonably request in writing from time to time,
     including, without limitation, accepting legal representation with respect
     to such claim by an attorney reasonably selected by the Company,

              (iii) cooperate with the Company in good faith in order
     effectively to contest such claim, and

                                       11


              (iv) permit the Company to participate in any proceedings
     relating to such claim;

provided, however, that the Company shall bear and pay directly all costs and
- --------  -------
expenses (including additional interest and penalties) incurred in connection
with such contest and shall indemnify and hold the Executive harmless, on an
after-tax basis, for any Excise Tax or income tax (including interest and
penalties with respect thereto) imposed as a result of such representation and
payment of costs and expenses.  Without limitation on the foregoing provisions
of this Section 9(c), the Company shall control all proceedings taken in
connection with such contest and, at its sole option, may pursue or forgo any
and all administrative appeals, proceedings, hearings and conferences with the
taxing authority in respect of such claim and may, at its sole option, either
direct the Executive to pay the tax claimed and sue for a refund or contest the
claim in any permissible manner, and the Executive agrees to prosecute such
contest to a determination before any administrative tribunal, in a court of
initial jurisdiction and in one or more appellate courts, as the Company shall
determine; provided, however, that if the Company directs the Executive to pay
           --------  -------
such claim and sue for a refund, the Company shall advance the amount of such
payment to the Executive, on an interest-free basis and shall indemnify and hold
the Executive harmless, on an after-tax basis, from any Excise Tax or income tax
(including interest or penalties with respect thereto) imposed with respect to
such advance or with respect to any imputed income with respect to such advance;
and further provided that any extension of the statute of limitations relating
    ------- --------
to payment of taxes for the taxable year of the Executive with respect to which
such contested amount is claimed to be due is limited solely to such contested
amount.  Furthermore, the Company's control of the contest shall be limited to
issues with respect to which a Gross-Up Payment would be payable hereunder and
the Executive shall be entitled to settle or contest, as the case may be, any
other issue raised by the Internal Revenue Service or any other taxing
authority.

          (d) If, after the receipt by the Executive of an amount advanced by
the Company pursuant to Section 9(c), the Executive becomes entitled to receive
any refund with respect to such claim, the Executive shall (subject to the
Company's complying with the requirements of Section 9(c)) promptly pay to the
Company the amount of such refund (together with any interest paid or credited
thereon after taxes applicable thereto).  If, after the receipt by the Executive
of an amount advanced by the Company pursuant to Section 9(c), a determination
is made that the Executive shall not be entitled to any refund with respect to
such claim and the Company does not notify the Executive in writing of its
intent to contest such denial of refund prior to the expiration of 30 days after
such determination, then such advance shall be forgiven and shall not be
required to be repaid and the amount of such advance shall offset, to the extent
thereof, the amount of Gross-Up Payment required to be paid.

     10.  Confidential Information.  The Executive shall hold in a fiduciary
          ------------------------
capacity for the benefit of the Company all secret or confidential information,
knowledge or data relating to the Company or any of its affiliated companies,
and their respective businesses, which shall have been obtained by the Executive
during the Executive's employment by the Company or any of its affiliated
companies and which shall not be or become public knowledge (other than by acts
by the Executive or representatives of the Executive in violation of this
Agreement).  After termination of the Executive's employment with the Company,
the Executive shall not, without the prior written consent of the Company or as
may otherwise be required by law or legal

                                       12


process, communicate or divulge any such information, knowledge or data to
anyone other than the Company and those designated by it. In no event shall an
asserted violation of the provisions of this Section 10 constitute a basis for
deferring or withholding any amounts otherwise payable to the Executive under
this Agreement.

     11.  Successors.
          ----------

          (a) This Agreement is personal to the Executive and without the prior
written consent of the Company shall not be assignable by the Executive
otherwise than by will or the laws of descent and distribution.  This Agreement
shall inure to the benefit of and be enforceable by the Executive's legal
representatives.

          (b) This Agreement shall inure to the benefit of and be binding upon
the Company and its successors and assigns.

          (c) The Company will require any successor (whether direct or
indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business and/or assets of the Company to assume
expressly and agree to perform this Agreement in the same manner and to the same
extent that the Company would be required to perform it if no such succession
had taken place.  As used in this Agreement, "Company" shall mean the Company as
hereinbefore defined and any successor to its business and/or assets as
aforesaid.

     12.  Miscellaneous.
          -------------

          (a) This Agreement shall be governed by and construed in accordance
with the laws of the State of Delaware, without reference to principles of
conflict of laws.  The captions of this Agreement are not part of the provisions
hereof and shall have no force or effect.  This Agreement may not be amended or
modified otherwise than by a written agreement executed by the parties hereto or
their respective successors and legal representatives.

          (b) All notices and other communications hereunder shall be in writing

compliance with any provision of this Agreement or the failure to assert any
right the Executive or the Company may have hereunder, including, without
limitation, the right of the Executive to terminate employment for Good Reason
pursuant to Section 5(c)(i)-(v) of this Agreement, shall not be deemed to be a
waiver of such provision or right or any other provision or right of this
Agreement.

          (f) The Executive and the Company acknowledge that, except as may
otherwise be provided under any other written agreement between the Executive
and the Company, the employment of the Executive by the Company is "at will"
and, subject to Section 1(a) hereof, prior to the Effective Date, the
