Northrop Grumman Corporation
1840 Century Park East
Los Angeles, California 90067

Gentlemen:

     In connection with our mutual consideration of a possible negotiated
transaction (a "Transaction") involving Newport News Shipbuilding Inc.
("NNS") and Northrop Grumman Corporation ("NGC"), NGC has requested certain
information with respect to NNS and NNS has requested certain information
with respect to NGC. Each party is prepared to make available to the other
party certain information which is non-public, confidential or proprietary
in nature regarding NNS or NGC, as the case may be, and which may be
disclosed either in written form or orally (the "Evaluation Material").
With respect to any information disclosed in connection with a possible
Transaction or otherwise pursuant to this Agreement, the party who has
disclosed such information or on whose behalf such information has been
disclosed is referred to herein as the "disclosing party" and the other
party is referred to herein as the "receiving party".

     By execution of this letter agreement (the "Agreement"), NNS and NGC
agree to treat all Evaluation Material received pursuant to the terms of
this Agreement confidentially and to observe the terms and conditions set
forth herein. For purposes of this Agreement, Evaluation Material shall
include all information, regardless of the form in which it is communicated
or maintained (whether prepared by the disclosing party or otherwise) that
contains or otherwise reflects information concerning the disclosing party
that the receiving party or its Representatives (as defined below) may be
provided by or on behalf of the disclosing party in the course of the
receiving party's evaluation of a possible Transaction. The term
"Evaluation Material" shall also include all reports, analyses, notes,
compilations, forecasts, studies or other documents or information prepared
by the receiving party or its Representatives that are based on, contain or
reflect any Evaluation Material ("Notes"). The term "Representatives" shall
include a party's directors, officers, employees, partners, affiliates,
agents, advisors, lawyers, accountants, consultants and financial advisors
or representatives.

     The term "Evaluation Material" does not include any information that
(i) is or becomes generally available to the public other than as a result
of a disclosure directly or indirectly by the receiving party or any of its
Representatives, (ii) is or was available to the receiving party on a
non-confidential basis from a source other than the disclosing party or its
affiliates or advisors, provided that the source of such information was
not known by the receiving party or any of its Representatives, after
reasonable investigation, to be bound by a confidentiality agreement with
the disclosing party or any of its affiliates or any other contractual,
legal or fiduciary obligation of confidentiality to the disclosing party or
any of its affiliates with respect to such material or (iii) has been
independently acquired or developed by the receiving party or any of its
Representatives without violating any of the provisions of this Agreement.

     Each party agrees that it will keep the Evaluation Material received
pursuant to the terms of this Agreement confidential and will not use the
Evaluation Material for any purpose other than determining whether such
party wishes to enter into a Transaction. Until the end of five years from
the date of this Agreement, each party agrees not to disclose or allow
disclosure to others of any Evaluation Material received pursuant to the
terms of this Agreement, except that each party may disclose Evaluation
Material to its Representatives to the extent necessary to permit such
Representatives to assist such party in making the determination referred
to in the prior sentence; provided, however, that each party shall require
each of its Representatives to be bound by the terms of this Agreement to
the same extent as if it was a party hereto and each party shall be
responsible for any breach of this Agreement by any of its Representatives.

     Each party agrees that it will not use the Evaluation Material
received pursuant to the terms of this Agreement in any way directly or
indirectly detrimental to the other party. In particular, the receiving
party agrees that for a period of two years from the date of signing of
this Agreement the receiving party and its affiliates will not, as a result
of knowledge or information obtained from the Evaluation Material or
otherwise in connection with a possible Transaction, employ or attempt to
employ or divert any employee of the disclosing party.

     Each party understands and acknowledges that none of the disclosing
party or its affiliates, agents, advisors or representatives (i) have made
or make any representation or warranty, expressed or implied, as to the
accuracy, completeness or reasonableness of the Evaluation Material or (ii)
shall have any liability whatsoever to the receiving party or its
Representatives relating to or resulting from the use of the Evaluation
Material or any errors therein or omission therefrom. Each party agrees
that it is not entitled to rely on the accuracy or completeness of the
Evaluation Material and that it will be entitled to rely solely on the
representations and warranties made to such party by the other party in any
definitive agreement.

     In the event that the receiving party or anyone to whom it transmits
any Evaluation Material in accordance with this Agreement is requested or
required (by deposition, interrogatory, request for documents, subpoena,
civil investigative demand or similar process), in connection with any
proceeding, to disclose any Evaluation Material, the receiving party will
give the disclosing party prompt written notice of such request or
requirement (and, in any event, before complying with any such request or
requirement) so that the disclosing party may seek an appropriate
protective order or other remedy and/or waive compliance with the
provisions of this Agreement, and the receiving party will cooperate with
the disclosing party to obtain such protective order. In the event that
such protective order or other remedy is not obtained or the disclosing
party waives compliance with the relevant provisions of this Agreement, the
receiving party (or such other persons to whom such request is directed)
will furnish only that portion of the Evaluation Material which, in the
written opinion of its counsel, is legally required to be disclosed and,
upon the disclosing party's request, use its best efforts to obtain
assurances that confidential treatment will be accorded to such
information.

     If either party decides that it does not wish to proceed with a
Transaction, such party will promptly notify the other party of that
decision. In that case, or if either party shall elect at any time to
terminate further access by the other party to the Evaluation Material for
any reason, each party will promptly destroy or redeliver to the other
party all copies of the Evaluation Material, destroy all Notes, delete any
non-oral information incapable of physical delivery (including, but not
limited to, Evaluation Material held on any computer or word processor) and
deliver to the other party a certificate executed by one of its duly
authorized officers indicating that the requirements of this sentence have
been satisfied in full. Notwithstanding the return or destruction of
Evaluation Material and Notes, each party and its Representatives will
continue to be bound by its obligations of confidentiality and other
obligations hereunder.

     Each party agrees that unless and until a definitive agreement between
the parties with respect to any Transaction has been executed and
delivered, neither party will be under any legal obligation of any kind
whatsoever with respect to such Transaction (other than as contained
herein).

     Each party agrees that monetary damages would not be a sufficient
remedy for any breach of this Agreement by it or its Representatives, that
in addition to all other remedies each party shall be entitled to specific
performance and injunctive or other equitable relief as a remedy for any
such breach, and neither party will oppose any application for injunctive
relief, and each party further agrees to waive, and to use its best efforts
to cause its Representatives to waive, any requirements for the securing or
posting of any bond in connection with such remedy. In the event of
litigation relating to this Agreement, if a court of competent jurisdiction
determines that either party or any of its Representatives has breached
this Agreement, such party shall be liable and pay to the other party all
expenses (including reasonable legal fees) in connection with such
litigation, including any appeal therefrom.

     In the event that any provision or portion of this Agreement is
determined to be invalid or unenforceable for any reason, in whole or in
part, the remaining provisions of this Agreement shall be unaffected
thereby and shall remain in full force and effect to the fullest extent
permitted by applicable law.

     This Agreement shall be governed by, and construed and enforced in
accordance with, the laws of the State of New York without regard to the
conflicts of laws principles thereof. Each party hereby consents to
nonexclusive jurisdiction of any Federal court or state court located in
New York.

     If you are in agreement with the foregoing, please so indicate by
signing, dating and returning one copy of this Agreement, which will
constitute our agreement with respect to the matters set forth herein.

                 Very truly yours,



                 NEWPORT NEWS SHIPBUILDING INC.
