                               PROSPECTUS SUMMARY
 
    THE FOLLOWING SUMMARY IS QUALIFIED IN ITS ENTIRETY BY, AND SHOULD BE READ IN
CONJUNCTION  WITH, THE MORE  DETAILED INFORMATION AND  FINANCIAL DATA (INCLUDING
FINANCIAL STATEMENTS, PRO FORMA FINANCIAL  DATA AND THE NOTES THERETO)  INCLUDED
ELSEWHERE IN THIS PROSPECTUS OR INCORPORATED HEREIN BY REFERENCE.
 
                                  THE COMPANY
 
    Northrop  Grumman  Corporation  (the "Company")  is  an  advanced technology
aerospace and  defense company  operating primarily  in two  business  segments:
electronics and systems integration and military and commercial aircraft. Within
the  electronics and systems integration segment,  the Company is engaged in the
design, development  and manufacture  of a  wide variety  of complex  electronic
products  such as  airborne radar,  surveillance and  battle management systems,
electronic countermeasures, precision weapons, antisubmarine warfare systems and
air traffic  control  systems.  Within  the  military  and  commercial  aircraft
segment,  the Company  is engaged  in the  design, development,  manufacture and
modification of military aircraft and commercial aerostructures. The Company  is
also engaged in the design, development, and manufacture of information systems,
marine  propulsion and power generation systems  and a variety of other products
and services. Approximately three-fourths of the Company's revenues in 1996  are
expected  to be generated from the U.S.  Department of Defense (the "DOD"), with
the balance provided by contracts with commercial aerospace manufacturers, other
U.S. government agencies and various foreign customers.
 
    The Company has a balance of programs in both the production and development
phases. While  production  programs generally  involve  less risk  and  generate
greater  cash flow than development programs, development programs are essential
for future growth  opportunities. Based  on its  backlog and  business mix,  the
Company  believes  that  its  cash  flow  from  operations  as  compared  to its
investment requirements will result in significant cash flow available for  debt
reduction, dividends and other uses over the next several years.
 
    Many  of the  Company's programs  are among  the principal  programs for the
various branches of the  U.S. military. The Company  is the prime contractor  on
the  B-2 Stealth Bomber, the only  strategic bomber currently in production; the
principal subcontractor  on  the  F/A-18C/D  Hornet,  the  U.S.  Navy's  primary
strike/attack  aircraft,  as  well as  on  the next  generation  F/A-18E/F Super
Hornet; the prime  contractor on  the E-2C  Hawkeye, the  U.S. Navy's  principal
early  warning, command and  control aircraft; the prime  contractor for the E-8
Joint STARS aircraft  radar system, which  will be the  primary airborne  ground
surveillance  and battle management system for the  U.S. Air Force and Army; the
prime  contractor  on   the  BAT  "Brilliant"   self-guided  submunition   under
development  for the U.S.  Army; the supplier  of the APG-68  Fire Control Radar
used on the F-16, one of the most widely used fighter aircraft in the world; the
supplier of the ARSR-4 Long Range Radar, a three-dimensional air traffic control
radar system  used  by  the  U.S.  Air  Force  and  the  U.S.  Federal  Aviation
Administration;  and the  supplier of the  AN/APY-1, 2  surveillance radar which
provides  real-time,  all-altitude  and  beyond-the-horizon  target   detection,
identification and tracking for the E-3 AWACS surveillance aircraft.
 
    The  Company is also one of  the world's leading manufacturers of commercial
aerostructures and components.  The Company manufactures  major portions of  the
Boeing  747,  757 and  767 jetliners  as well  as significant  subassemblies and
components for other commercial aircraft, including the Boeing 777 jetliner.
 
                                    STRATEGY
 
    The Company intends to strengthen its position as a leader in the  aerospace
and  defense  industry by  pursuing the  following  strategies: (i)  focusing on
segments of defense markets that are  growing and where the Company has  premier
technological  capabilities, particularly in electronics and electronics systems
integration; and (ii) leveraging its airframe design expertise and manufacturing
strengths to  remain  a  key  competitor in  military  aircraft  and  commercial
aerostructures.  The  Company  has  been pursuing  these  strategies  since 1992
through both  internal initiatives  and acquisitions  and, as  a result,  enjoys
leading  positions in those market segments in  which it chooses to compete. The
Company's primary objective in pursuit of these strategies is to maximize  total
return on investment.

<PAGE>
    The   Company   is   transforming   itself   from   primarily   an  aircraft
designer/manufacturer to an electronics and  systems integration company with  a
leading  airframe  and  aerostructures  business.  In  early  1994,  the Company
significantly expanded its electronics business with the acquisition of  Grumman
Corporation  ("Grumman"), a  leading electronic systems  integration company. In
March  of  1996,  the  Company   acquired  the  Electronics  Systems  Group   of
Westinghouse  Electric  Corporation  ("ESG").  ESG  is  a  leading  producer  of
sophisticated electronics for defense,  government and commercial  applications.
As  a result of these acquisitions, the Company expects that its electronics and
systems integration revenues will approximate 50% of total revenues in 1996  and
that this percentage will continue to increase in the future.
 
    This  strategic  transformation positions  the Company  to meet  the growing
needs of the DOD for  more sophisticated electronics and integrated  electronics
systems.  Since the end of the Cold War, the DOD has recognized the necessity of
maintaining an  effective fighting  force with  fewer defense  dollars,  thereby
placing a premium on sophisticated systems that provide long-range surveillance,
battle  management and  precision-strike capabilities. As  military systems have
become more  complex, integration  of the  electronic functions  of the  various
platforms, weapons and support systems has become increasingly important. Budget
constraints have also encouraged spending on program modifications, upgrades and
extensions  rather than on  new development programs,  further increasing demand
for sophisticated electronics systems. As  a technological leader in  designing,
manufacturing and integrating the sophisticated electronics systems that provide
long-range  surveillance, battle  management and  precision-strike capabilities,
the Company believes that it is well positioned to serve the electronic  systems
market.
 
    The  Company  has also  strengthened  its military  and  commercial aircraft
segment.  In  1992,  the  Company  acquired  49%  of  Vought  Aircraft   Company
("Vought"),  a leading  manufacturer of commercial  and military aerostructures,
and in  1994 acquired  the remaining  51% of  Vought and  the military  aircraft
business  of Grumman. These acquisitions  and the Company's internal initiatives
have enabled the Company  to establish a leading  position in military  aircraft
and  commercial aerostructures. The Company believes  that it will maintain this
leadership position as  a result  of its airframe  design experience,  including
stealth technology, as well as its cost-competitive manufacturing capabilities.
 
                               ACQUISITION OF ESG
 
    On  March  1,  1996,  the  Company  completed  the  acquisition  of  ESG for
approximately $3  billion  in  cash  (the "Acquisition").  For  the  year  ended
December  31, 1995, ESG  generated revenue of $2.6  billion. The Acquisition was
financed with a combination  of bank borrowings  and intermediate and  long-term
notes  and debentures. The business of ESG  is now operated as the Company's new
Electronic Sensors and Systems Division ("ESSD").
 
    ESSD is a leading supplier of electronic systems for defense, government and
commercial applications.  It  employs  nearly  12,000  people  worldwide  at  15
operating  locations, primarily  in the  United States.  ESSD has  a diversified
portfolio of programs  with no single  program accounting for  more than 10%  of
revenues   in  1995.  Approximately  one-half   of  ESSD's  1995  revenues  were
attributable to  radar technology  applied to  surveillance, fire  control,  air
traffic  control and  other purposes. ESSD  also designs  and manufactures other
avionics products,  electro-optical systems,  undersea and  marine products  and
material handling systems.
 
    The  Acquisition represents a  substantial step in  the Company's continuing
transformation from an aircraft  designer/manufacturer to a defense  electronics
and  systems  integration company  with  a leading  aircraft  and aerostructures
business. The Acquisition enables the Company  to serve a larger customer  base,
domestically  and internationally, and is expected to provide the opportunity to
achieve revenue growth  and greater  cash flow stability.  The Acquisition  will
also  enable the Company to  enhance its role on  important programs such as E-8
Joint STARS and BAT, and  to expand its business into  the areas of air  traffic
control and anti-submarine warfare systems.

             UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL DATA
 
    The  following unaudited  pro forma condensed  combined financial statements
reflect the  ESG  acquisition  and  are  based  upon  the  historical  financial
statements  of  the  Company and  ESG  for  the period  indicated,  combined and
adjusted to give  effect to  the ESG acquisition  using the  purchase method  of
accounting.  The unaudited pro  forma condensed combined  statement of financial
position gives effect to the ESG acquisition  as if it had occurred on  December
31,  1995. The unaudited pro forma  condensed combined statement of income gives
effect to the  ESG acquisition as  if it had  occurred on January  1, 1995.  The
adjustments  to the unaudited pro forma  financial statements do not give effect
to the proposed  issuance of shares  in the  Offerings and the  use of  proceeds
therefrom. The pro forma adjustments are described in the accompanying notes.
 
    The purchase price has been allocated to the assets and liabilities acquired
based  upon preliminary estimates of their respective fair values. The unaudited
pro forma financial information  does not give effect  to any synergies or  cost
savings  that the Company  may realize as  a result of  the ESG acquisition. The
Company is compiling data to determine those business areas and facilities  that
do  not fit in  its long-term strategy  and intends to  complete this process by
December 31, 1996. During the remainder of 1996, the estimates of fair value for
other assets  and liabilities  will be  refined  and changes,  if any,  will  be
reflected in the Company's periodic Exchange Act filings for 1996.
 
    The  unaudited  pro forma  condensed combined  financial statements  are not
necessarily indicative of the results of operations or financial position of the
combined company that would  have occurred had the  ESG acquisition occurred  on
the  dates  indicated  above,  nor are  they  necessarily  indicative  of future
operating results or financial position.
 
    The unaudited pro  forma condensed combined  financial statements should  be
read   in  conjunction  with  the  audited  consolidated  financial  statements,
including the notes thereto, of  the Company in its  Annual Report on Form  10-K
for  the year  ended December  31, 1995  and of  ESG contained  in the Company's
Current Report on Form 8-K filed March 18, 1996, both of which are  incorporated
herein  by reference. See "Available  Information" and "Incorporation of Certain

(a)Adjustments to record $3 billion in loans obtained to finance the acquisition
   of ESG, and to assign the  purchase price to assets acquired and  liabilities
   assumed.  The allocation of  the purchase price to  assets and liabilities is
   based upon preliminary estimates of their respective fair values. The Company
   is compiling data to  determine the final allocation  of the purchase  price,
   which process will be completed by December 31, 1996.
 
(b) Adjustment  to  record  the  preliminary estimate  of  ESG  retiree benefits
    liabilities in excess of the market value of related assets at December  31,
    1995.  The  Company is  reviewing  the actuarial  data  relative to  the ESG
    retiree benefit plans and based on  the results of the review the  liability
    may be adjusted.
 
(c) Adjustment  to reflect  change in method  of recognizing  revenue on certain
    long-term contracts applied  by ESG  to conform with  the Company's  revenue
    recognition policy and to eliminate ESG's intercompany sales.
 
(d)Adjustment  to amortize  goodwill over  a 40-year  period on  a straight-line
   basis and other purchased intangibles  on a straight-line basis over  periods
   ranging from 1 to 10 years, with a combined weighted average life of 33 years

                                  THE COMPANY
 
GENERAL
 
    Northrop Grumman  Corporation  (the  "Company") is  an  advanced  technology
aerospace  and  defense company  operating primarily  in two  business segments:
electronics and systems integration and military and commercial aircraft. Within
the electronics and systems integration segment,  the Company is engaged in  the
design,  development and  manufacture of  a wide  variety of  complex electronic
products such as  airborne radar,  surveillance and  battle management  systems,
electronic countermeasures, precision weapons, antisubmarine warfare systems and
air  traffic  control  systems.  Within  the  military  and  commercial aircraft
segment, the  Company is  engaged in  the design,  development, manufacture  and
modification  of military aircraft and commercial aerostructures. The Company is
also engaged in the design, development and manufacture of information  systems,
marine  propulsion and power generation systems  and a variety of other products
and services. Approximately three-fourths of the Company's revenues in 1996  are
expected  to be generated from the U.S.  Department of Defense (the "DOD"), with
the balance provided by contracts with commercial aerospace manufacturers, other
U.S. government agencies and various foreign customers.
 
    On March 1, 1996,  the Company completed the  acquisition of the  Electronic
Systems  Group of Westinghouse  Electric Corporation which  is now the Company's
Electronic Sensors and Systems Division ("ESSD"). ESSD is a leading supplier  of
electronics  systems for  defense, government and  commercial applications. This
acquisition further enhances the  Company's electronics and systems  integration
capabilities,  broadens  the  Company's product  offerings  and  provides growth
opportunities in key defense and commercial markets. See "-- Acquisition of ESG"
and "-- Divisions -- Electronic Sensors and Systems Division."
 
    In 1992  the Company  acquired a  49% interest  in Vought  Aircraft  Company
("Vought"), a leading manufacturer of commercial and military aerostructures. In
1994  the  Company acquired  Grumman Corporation  ("Grumman") and  the remaining
portion of Vought.  With Grumman,  the Company  acquired a  premier supplier  of
electronic  surveillance and electronic systems  integration products as well as
military aircraft.
 
    The Company has a balance of programs in both the production and development
phases. While  production  programs generally  involve  less risk  and  generate
greater  cash flow than development programs, development programs are essential
for future growth  opportunities. Based  on its  backlog and  business mix,  the
Company  believes  that  its  cash  flow  from  operations  as  compared  to its
investment requirements will result in significant cash flow available for  debt
reduction, dividends and other uses over the next several years.
 
    Many  of the  Company's programs  are among  the principal  programs for the
various branches of the  U.S. military. The Company  is the prime contractor  on
the  B-2 Stealth Bomber, the only  strategic bomber currently in production; the
principal subcontractor  on  the  F/A-18C/D  Hornet,  the  U.S.  Navy's  primary
strike/attack  aircraft,  as  well as  on  the next  generation  F/A-18E/F Super
Hornet; the prime  contractor on  the E-2C  Hawkeye, the  U.S. Navy's  principal
early  warning, command and  control aircraft; the prime  contractor for the E-8
Joint STARS aircraft  radar system, which  will be the  primary airborne  ground
surveillance  and battle management system for the  U.S. Air Force and Army; the
prime  contractor  on   the  BAT  "Brilliant"   self-guided  submunition   under
development  for the U.S.  Army; the supplier  of the APG-68  Fire Control Radar
used on the F-16, one of the most widely used fighter aircraft in the world; the
supplier of the ARSR-4 Long Range Radar, a three-dimensional air traffic control
radar system  used  by  the  U.S.  Air  Force  and  the  U.S.  Federal  Aviation
Administration;  and the  supplier of the  AN/APY-1, 2  surveillance radar which
provides  real-time,  all-altitude  and  beyond-the-horizon  target   detection,
identification and tracking for the E-3 AWACS surveillance aircraft.
 
    The  Company is also one of  the world's leading manufacturers of commercial
aerostructures and components.  The Company manufactures  major portions of  the
Boeing  747, 757  and 767  jetliners, as  well as  significant subassemblies and
components for other commercial aircraft, including the Boeing 777 jetliner.
 
                                       14

<PAGE>
    The Company was founded in 1939 and reincorporated in 1985 in Delaware.  The
Company's  executive offices are located at 1840 Century Park East, Los Angeles,
California 90067 and its telephone number is (310) 553-6262.
 
STRATEGY
 
    The Company intends to strengthen its position as a leader in the  aerospace
and  defense  industry by  pursuing the  following  strategies: (i)  focusing on
segments of defense markets that are  growing and where the Company has  premier
technological  capabilities, particularly in electronics and electronics systems
integration; and (ii) leveraging its airframe design expertise and manufacturing
strengths to  remain  a  key  competitor in  military  aircraft  and  commercial
aerostructures.  The  Company  has  been pursuing  these  strategies  since 1992
through both  internal initiatives  and acquisitions  and, as  a result,  enjoys
leading  positions in those market segments in  which it chooses to compete. The
Company's primary objective in pursuit of these strategies is to maximize  total
return on investment.
 
    The  Company  is  transforming  itself  from  being  primarily  an  aircraft
designer/manufacturer to an electronics and  systems integration company with  a
leading  airframe  and  aerostructures  business.  In  early  1994,  the Company
significantly expanded its electronics business with the acquisition of Grumman.
In March of 1996, the Company acquired ESG, a leading producer of  sophisticated
electronics  for defense, government and commercial applications. As a result of
these acquisitions,  the  Company  expects  that  its  electronics  and  systems
integration  revenues will approximate nearly 50%  of total revenues in 1996 and
that this percentage will continue to increase in the future.
 
    This strategic  transformation positions  the Company  to meet  the  growing
needs  of the DOD for more  sophisticated electronics and integrated electronics
systems. Since the end of the Cold War, the DOD has recognized the necessity  of
maintaining  an  effective fighting  force with  fewer defense  dollars, thereby
placing a premium on sophisticated systems that provide long-range surveillance,
battle management and  precision-strike capabilities. As  military systems  have
become  more complex,  integration of  the electronic  functions of  the various
platforms, weapons and support systems has become increasingly important. Budget
constraints have also encouraged spending on program modifications, upgrades and
extensions rather than  on new development  programs, further increasing  demand
for  sophisticated electronics systems. As  a technological leader in designing,
manufacturing and integrating the sophisticated electronics systems that provide
long-range surveillance,  battle management  and precision-strike  capabilities,
the  Company believes that it is well positioned to serve the electronic systems
market.
 
    The Company  has  also strengthened  its  military and  commercial  aircraft
segment.  In  1992, the  Company acquired  49%  of Vought  and in  1994 acquired
Grumman and the remaining  51% of Vought. These  acquisitions and the  Company's
internal initiatives have enabled the Company to establish a leading position in
military  aircraft and commercial  aerostructures. The Company  believes that it
will maintain  this leadership  position  as a  result  of its  airframe  design
experience,  including  stealth  technology,  as  well  as  its cost-competitive
manufacturing capabilities.
 
ACQUISITION OF ESG
 
    On March  1,  1996,  the  Company  completed  the  acquisition  of  ESG  for
approximately  $3  billion  in  cash (the  "Acquisition").  For  the  year ended
December 31, 1995, ESG  generated revenue of $2.6  billion. The Acquisition  was
financed  with a combination  of bank borrowings  and intermediate and long-term
notes and debentures. The business of ESG  is now operated as the Company's  new
Electronic Sensors and Systems Division ("ESSD").
 
    ESSD is a leading supplier of electronic systems for defense, government and
commercial  applications.  It  employs  nearly  12,000  people  worldwide  at 15
operating locations,  primarily in  the United  States. ESSD  has a  diversified
portfolio  of programs with  no single program  accounting for more  than 10% of
revenues  in  1995.  Approximately  one-half   of  ESSD's  1995  revenues   were
attributable  to  radar technology  applied to  surveillance, fire  control, air
traffic control and  other purposes.  ESSD also designs  and manufactures  other
avionics  products, electro-optical  systems, undersea  and marine  products and
material handling systems.
 
                                       15

<PAGE>
    The Acquisition represents  a substantial step  in the Company's  continuing
transformation  from  an aircraft  designer/manufacturer  to an  electronics and
systems integration company with a leading aircraft and aerostructures business.
The  Acquisition  enables  the  Company   to  serve  a  larger  customer   base,
domestically  and internationally, and is expected to provide the opportunity to
achieve revenue growth  and greater  cash flow stability.  The Acquisition  will
also  enable the Company to  enhance its role on  important programs such as E-8
Joint STARS and BAT, and  to expand its business into  the areas of air  traffic
control and anti-submarine warfare systems.
 
DIVISIONS
 
    The  Company is organized  into five operating  divisions: Military Aircraft
Systems Division;  Electronic  Sensors  and Systems  Division;  Electronics  and
Systems Integration Division; Commercial Aircraft Division; and Data Systems and
Services   Division.  In   addition,  the  Company's   Advanced  Technology  and
Development Center provides product development and technology functions for all
of the operating divisions,  drawing on technologies and  skills in each of  the
divisions.
 
    MILITARY AIRCRAFT SYSTEMS DIVISION
 
    The  Military Aircraft Systems  Division is responsible  for the development
and manufacture of several types of military aircraft. The Company is the  prime
contractor  for  the B-2,  a strategic,  long-range,  large payload  bomber with
advanced stealth technology that  is capable of operating  at both high and  low
altitudes.  The B-2 is able to penetrate the most sophisticated air-defenses and
is capable of  responding more  quickly, from  greater distances  and with  more
accurate firepower than any other U.S. aircraft.
 
    The  Company is currently  under contract to provide  20 operational and one
test B-2 aircraft. All 21  aircraft are fully funded.  To date, the Company  has
delivered  six test aircraft and 11 of 15 production aircraft. At least five out
of the six test aircraft will be refurbished to an operational configuration and
delivered to the U.S.  Air Force. The Clinton  Administration has announced  its
intent,  and the Company has been asked  to provide a proposal, to refurbish the
remaining test aircraft  for subsequent  delivery to the  U.S. Air  Force as  an
operational vehicle. The U.S. Air Force currently operates a squadron of 10 B-2s
at Whiteman Air Force Base in Missouri. In addition, the B-2 program is expected
to  generate  maintenance and  support revenues  upon completion  of production.
While the Company  continues to seek  funding for additional  B-2s, there is  no
assurance that such funding will be available.
 
    The  Company is  the prime  or principal  subcontractor on  all of  the U.S.
Navy's carrier-based fighter, attack and  early warning aircraft, including  the
F/A-18.  For  more than  two  decades the  Company  has been  teamed  with prime
contractor McDonnell Douglas on the F/A-18 program. The F/A-18C/D Hornet is  the
U.S.  Navy's primary  strike/attack aircraft  and is  deployed by  the Navy from
aircraft carriers and by the Marines from  air bases. In total, more than  1,300
F/A-18  Hornets  have  been  delivered  to  the  U.S.  and  to  certain  foreign
governments. The Company  produces approximately 40%  of each F/A-18C/D  Hornet,
including  the center and  aft fuselage, twin vertical  tails and all associated
subsystems. The Company is also the  principal subcontractor on the U.S.  Navy's
newest combat aircraft, the F/A-18E/F Super Hornet, which successfully completed
its  first test flight in November 1995.  The F/A-18E/F Super Hornet has greater
range and payload, more powerful engines  and more advanced avionics and  weapon
systems  than the F/A-18C/D Hornet. The  Company will also produce approximately
40% of  each  F/A-18E/F  Super  Hornet.  The  first  production  deliveries  are
scheduled to begin in 1999, with initial operating capability expected in 2001.
 
    Modification  and enhancement of  existing airborne platforms  has become an
important part of the  military aircraft market. With  U.S. and foreign  defense
planners seeking modern systems at affordable costs, upgrading existing aircraft
can  be an attractive alternative  to the purchase of  new aircraft. The Company
provides a broad array of  aircraft upgrade, modification, overhaul and  support
services  for several operational  aircraft, including the  F-5, T-38, F-14, C-2
and A-10.  The  Company  is  also responsible  for  remanufacturing  Boeing  707
aircraft  as  the  platform  for  the Company's  E-8  Joint  STARS  program, for
structural enhancements of the  EA-6B Prowler and for  airframe upgrades of  the
E-2C Hawkeye.

<PAGE>
    ELECTRONIC SENSORS AND SYSTEMS DIVISION
 
    The Electronic Sensors and Systems Division ("ESSD") represents the acquired
business  of ESG. ESSD  has a diversified  portfolio of programs  with no single
program accounting for more than 10% of revenues in 1995. Approximately one-half
of ESSD's  1995  revenues  were  attributable to  radar  technology  applied  to
surveillance,  fire control, air  traffic control and  other purposes. ESSD also
designs and  manufactures  other  avionics  products,  electro-optical  systems,
underseas and marine products and material handling systems.
 
    With  its state-of-the-art  surveillance and imaging  technologies, ESSD has
gained significant positions on  a wide variety of  high priority platforms  for
the  DOD and certain  foreign governments. ESSD  produces radars and electronics
for military aircraft  and battlespace management  systems, including those  for
the  F-16 fighter, Apache  Longbow helicopter, B-1B  bomber, C-130 transport and
E-3 AWACS and E-8 Joint STARS surveillance aircraft.
 
    ESSD's products are also  present on numerous  development programs such  as
the  F-22 fighter and the Comanche helicopter. Should budget pressures force the
stretch-out of these next generation programs, ESSD is expected to benefit  from
an  increased demand for electronic upgrades and retrofits to existing aircraft.
For example, ESSD is  currently providing mid-life  fire control radar  upgrades
for the F-16.
 
    ESSD  is also a leading  supplier of air traffic  control radars to the U.S.
Federal Aviation Administration  and to  countries in Europe,  the Middle  East,
Africa,  Asia  and South  America. ESSD  is  the prime  contractor on  the ASR-9
terminal radar system which detects and displays aircraft and weather conditions
simultaneously,  helping  air   traffic  controllers   guide  aircraft   through
traffic-dense  regions  surrounding  airports.  The  international  air  traffic
control market is expected to increase  significantly, due in large part to  the
growth  of international air traffic and  infrastructure development in Asia and
Eastern Europe. The  Company believes that  ESSD is well  positioned to  benefit
from  this anticipated growth  in the international  air traffic control market.
ESSD also develops electronic countermeasures, tactical communication equipment,
space products and underseas  and marine technologies, including  anti-submarine
combat systems, surface ship propulsion and power generation equipment.
 
    International  sales are also an  increasingly important component of ESSD's
military electronics business.  The F-16  radar system,  ESSD's longest  running
program,  is installed in  the F-16s of  23 countries. In  addition to the F-16,
many other  DOD weapon  systems with  ESSD  subsystems, such  as the  E-3  AWACS
surveillance   aircraft  and  the  AH-64   Apache  helicopter,  have  been  sold
internationally.
 
    ELECTRONICS AND SYSTEMS INTEGRATION DIVISION
 
    The Electronics and Systems  Integration Division manages major  electronics
systems  programs.  The  Company is  the  overall systems  integrator  and prime
contractor for the E-8 Joint STARS,  the U.S. military's primary airborne  radar
system   which   is   designed  to   provide   real-time   detection,  location,
classification and tracking of hostile moving and stationary ground targets. The
surveillance capabilities of the E-8 Joint STARS will enable it to be a critical
part of future  battle management  systems. The E-8  Joint STARS  program is  in
limited  production and funding  has been approved  for the first  six E-8 Joint
STARS  production  aircraft  (designated  the  E-8C).  One  aircraft  has   been
delivered,  a second is expected to be  delivered in 1996 and the remaining four
aircraft are scheduled to  be delivered in 1997  and 1998. The Company  believes
that  U.S. government support for the E-8  Joint STARS program is strong, due in
part to  successful tests  and  operational activity  of prototype  aircraft  in
combat  conditions  in the  Persian  Gulf and  Bosnia.  The U.S.  government has
approved the  sale  of  E-8 Joint  STARS  aircraft  to NATO,  although  no  such
purchases have been committed to or funded.
 
    The  Company is the prime  contractor for the E-2C  Hawkeye, the U.S. Navy's
principal early  warning, command  and  control aircraft.  The E-2C  Hawkeye  is
designed  for missions such as air  defense, strike control, air traffic control
and search and rescue. The U.S. Navy recently received approval for a program of
36 E-2C aircraft, of which seven are under contract for delivery during 1997 and
1998. The Company is also involved with the Navy's upgrade program for  existing
E-2C aircraft. In response to upgraded threat

capabilities,   the  U.S.  Navy  continues  to  plan  additional  E-2C  avionics
improvements including data processing and capacity increases, passive detection
systems, radar  anti-jamming  improvements,  tactical program  updates  and  jam
resistant communication systems.
 
    The  Company  is the  prime contractor  on  the BAT  "Brilliant" self-guided
submunition program under  development for  the U.S.  Army. This  weapon may  be
carried  by a variety  of air vehicles  and is designed  to autonomously locate,
attack and destroy  tanks, armored vehicles  and other mobile  targets by  using
acoustic  and infrared sensors working in  combination with a high speed onboard
computer. Prototype manufacture began in 1992, and  the BAT is now in a  testing
phase to verify that the system meets all established requirements.
 
    COMMERCIAL AIRCRAFT DIVISION
 
    The  Commercial Aircraft Division is one of the world's leading suppliers of
aerostructures,  as  well  as  a  major  supplier  of  aircraft  components  for
commercial  and military use. The Company manufactures the fuselage and the tail
section for the Boeing 747, the tail section for the Boeing 757 and 767, various
other components  for  the Boeing  757,  767  and 777  and  major  subassemblies
(including  the tail section) for the McDonnell Douglas C-17 military transport.
In April 1995,  the Company entered  into an agreement  with Boeing to  continue
production  of the major sections of the 747, 757 and 767 aircraft into the next
century. The  Company also  produces  wings for  the  new Gulfstream  V  ("G-V")
business  jet program and components for  other aircraft. The G-V's first flight
was in November 1995, and aircraft deliveries to customers are expected to begin
in January 1997.
 
    While the Company's commercial aircraft deliveries declined in 1995 compared
to 1994,  the three  leading  jet-airliner manufacturers  collectively  recorded
substantially  increased  orders  for new  aircraft  in 1995  compared  to 1994.
Boeing, the Company's largest customer for commercial aerostructures,  announced
in  December 1995 and March 1996, planned increases in production rates for 1996
and 1997 for  its 747,  767 and 777  models and  a return to  current levels  of
production in the second quarter of 1997 for its 757 model following a reduction
in the fourth quarter of 1996. The Boeing labor strike, settled in January 1996,
will  cause some deliveries scheduled  for 1996 to be  made in 1997. The Company
has made  substantial  investments  in  productivity  improvements  and  capital
equipment  to further improve its competitive position in the growing commercial
aerostructure marketplace.
 
    DATA SYSTEMS AND SERVICES DIVISION
 
    The Data  Systems  and Services  Division  provides data  processing  system
services  for external  customers as  well as  the Company's  various divisions.
Included among these services are space station program support services, flight
simulator maintenance services  and the development  of data processing  systems
for  a wide variety  of U.S. Government entities  and applications. The Division
also provides operational and support services to U.S. Air Force bases, an  area
of  potential  growth  if  the  U.S.  Government  increases  the  outsourcing of
maintenance and support activities.
 
RECENT DEVELOPMENT
 
    In the first quarter  of 1996, a  jury trial commenced  with respect to  the
remaining  issues in the litigation described  in the Company's Annual Report on
Form 10-K  for 1995  entitled  U.S. EX  REL DAVID  PETERSON  AND JEFF  KNOLL  V.
NORTHROP   CORPORATION.  The  government  has  asserted  three  separate  claims
totalling approximately $13.5 million, including a claim for alleged mischarging
of approximately  $12 million  in violation  of the  False Claims  Act.  Damages
awarded  under the  False Claims  Act are  subject to  doubling or  trebling and
possible additional  penalties including  disallowance of  attorneys' fees.  The
Company  denies  the  material  allegations  of  the  claims  and  is vigorously
defending the action.

                          DESCRIPTION OF CAPITAL STOCK
 
AUTHORIZED CAPITAL STOCK
 
    Under the Company's Certificate of Incorporation, the total number of shares
of stock which the Company has authority to issue is 210,000,000, consisting  of
200,000,000  shares of Common  Stock, par value $1.00  per share, and 10,000,000
shares of Preferred  Stock, $1.00  par value  per share.  As of  April 5,  1996,
49,620,303  shares of  Common Stock were  issued and  outstanding, not including
shares reserved  for issuance  under the  Company's stock  plans. No  shares  of
Preferred  Stock were issued and  outstanding on such date.  The Common Stock is
listed on the New York Stock Exchange and the Pacific Stock Exchange.
 
PREFERRED STOCK
 
    Under the Company's Certificate of Incorporation, the Board of Directors  of
the  Company is authorized,  without further stockholder  action, to provide for
the issuance of Preferred Stock in one or more series, with such designations of
titles, dividend rates, redemption provisions, special or relative rights in the
event of liquidation, dissolution,  distribution or winding  up of the  Company,
sinking  fund provisions,  conversion provisions,  voting rights,  and any other
preferences,  privileges,  powers,   rights,  qualifications,  limitations   and
restrictions,  as shall  be set forth  as and  when established by  the Board of
Directors of the Company.
 
DESCRIPTION OF COMMON STOCK
 
    The holders of Common Stock are entitled to receive such dividends as may be
declared from  time to  time by  the Board  of Directors  out of  funds  legally
available  therefor subject to  restrictions on the  declaration of dividends on
the Common Stock which may be imposed in connection with the issuance of  shares
of  any  class or  series  of Preferred  Stock.  The Company's  principle credit
agreement contains provisions restricting dividends and other distributions  and
the   purchase  or   redemption  of  shares   of  Common   Stock  under  certain
circumstances. Except as otherwise provided by law, the holders of Common  Stock
are  entitled  to one  vote per  share on  all  matters submitted  to a  vote of
stockholders and do not have cumulative  voting rights. Holders of Common  Stock
are  entitled to  receive, upon  any liquidation  of the  Company, all remaining
assets available  for distribution  to stockholders  after satisfaction  of  the
Company's  liabilities and the  preferential rights of  any Preferred Stock that
may then be issued and outstanding. The outstanding shares of Common Stock  are,
and  the shares offered hereby will be, upon payment therefore by the purchasers
thereof, fully  paid and  nonassessable. The  holders of  Common Stock  have  no
preemptive,  conversion or redemption  rights. The registrar  and transfer agent
for the Common Stock is Chemical Mellon Shareholders Services, L.L.C., New York.
 
COMMON STOCK PURCHASE RIGHTS
 
    In 1988, the Company's Board of Directors authorized the distribution of one
Common Stock Purchase  Right (a "Right")  for each outstanding  share of  Common
Stock.
 
    As distributed, the Rights trade together with the Common Stock. They may be
exercised  or traded  separately 10  business days  after a  person or  group of
persons acquires 15% or more of  the outstanding Common Stock, or announces  the
intention  to make a tender  offer for 30% or  more of the Company's outstanding
Common Stock. Upon exercise, each Right  entitles the holder thereof to buy  one
share  of Common  Stock at  a price  of $105.  If a  Person acquires  15% of the
outstanding voting power of  the Company, each Right  (other than those held  by
the  acquiror)  will entitle  its holder  to purchase,  at the  Right's exercise
price, shares of Common  Stock having a  market value of  two times the  Right's
exercise  price. Additionally, if the  Company is acquired in  a merger or other
business combination, each  Right (other  than those  held by  the surviving  or
acquiring  company) will entitle its holder to purchase, at the Right's exercise
price, shares of the  acquiring company's common stock  (or Common Stock of  the
Company  if it is the surviving corporation)  having a market value of two times
the Right's exercise price.
 
    Rights may be redeemed at the option of the Board of Directors for $.02  per
Right at any time prior to the earlier of the expiration of the Rights or within
10  days following the date that a person  or persons acquire 15% of the general
voting power of the Company. The Board may amend the Rights at any time  without
stockholder approval. The Rights will expire by their terms in October 1998.

                 CERTAIN UNITED STATES FEDERAL TAX CONSEQUENCES
                         FOR NON-UNITED STATES HOLDERS
 
    The  following  is a  general discussion  of  certain United  States federal
income and estate tax  consequences of the ownership  and disposition of  Common
Stock  by a  holder of  such stock  that, for  United States  federal income tax
purposes, is not a "United States  person" (a "Non-United States Holder").  This
discussion  is  not  intended  to  be  exhaustive  and  is  based  on  statutes,
regulations, rulings and court decisions as currently in effect all of which may
be changed  either  retroactively or  prospectively.  This discussion  does  not
consider  any specific  facts or  circumstances that  may apply  to a particular
Non-United States Holder (including, for example, the fact that, in the case  of
a  Non-United States Holder that is a  partnership, the U.S. tax consequences of
purchasing,  holding  and  disposing  of   Common  Stock  may  be  affected   by
determinations  made both at the partnership  and the partner level) and applies
only to Non-United  States Holders that  hold Common Stock  as a capital  asset.
PROSPECTIVE  INVESTORS ARE  URGED TO  CONSULT THEIR  TAX ADVISORS  REGARDING THE
UNITED STATES FEDERAL TAX  CONSEQUENCES OF ACQUIRING,  HOLDING AND DISPOSING  OF
COMMON  STOCK (INCLUDING  SUCH INVESTOR'S  STATUS AS  A UNITED  STATES PERSON OR
NON-UNITED STATES HOLDER) AS WELL AS  ANY TAX CONSEQUENCES THAT MAY ARISE  UNDER
THE LAWS OF ANY STATE, MUNICIPALITY OR OTHER TAXING JURISDICTION.
 
    For  purposes of this discussion, "United  States person" means a citizen or
resident of the United States, a corporation or partnership created or organized
in the United States or under the laws of the United States or of any  political
subdivision  thereof, or an estate or trust  whose income is includable in gross
income for United States federal income  tax purposes regardless of its  source.
An  alien individual  generally is  treated as  a United  States person  for any
calendar year if either (i) the individual  is present in the United States  183
days  or more during such calendar year or (ii) the individual is present in the
United States at  least 31 days  during such calendar  year and the  sum of  the
number  of days present during such calendar  year, one-third the number of days
present during the first preceding year and one-sixth the number of days present
during the second preceding year is 183 or more.
 
DIVIDENDS
 
    Dividends paid to a  Non-United States Holder generally  will be subject  to
withholding  of United States federal income tax  at the rate of 30%, unless the
withholding rate is reduced  under an applicable income  tax treaty between  the
United  States and the country of tax residence of the Non-United States Holder.
No U.S. withholding will apply if  the dividend is effectively connected with  a
trade  or business conducted  within the United States  by the Non-United States
Holder (or, alternatively, where an income  tax treaty applies, if the  dividend
is  effectively connected with  a permanent establishment  maintained within the
United States by the Non-United States Holder), but, instead, the dividend  will
be subject to the United States federal income tax on net income that applies to
United  States  persons (and,  with respect  to corporate  holders, may  also be
subject to the branch profits tax).  A Non-United States Holder may be  required
to  satisfy certain certification requirements in order to claim treaty benefits
or to otherwise  claim a reduction  of or exemption  from withholding under  the
foregoing  rules. A Non-United States Holder that is eligible for a reduced rate
of U.S. withholding  tax pursuant to  a tax treaty  may obtain a  refund of  any
excess amounts currently withheld by filing an appropriate claim for refund with
the United States Internal Revenue Service (the "Service").
 
GAIN ON DISPOSITION
 
    Subject  to special rules  described below, a  Non-United States Holder will
generally not be subject to United States federal income tax on gain  recognized
on  a sale or other  disposition of Common Stock  unless the gain is effectively
connected with a  trade or business  conducted within the  United States by  the
Non-United States Holder (or, alternatively, where an income tax treaty applies,
unless  the  gain  is  effectively  connected  with  a  permanent  establishment
maintained within the United States by  the Non-United States Holder). Any  such
effectively  connected gain would be subject to the United States federal income
tax on net income that  applies to United States  persons (and, with respect  to
corporate  holders, may also be subject to  the branch profits tax). Such tax is
not collected by withholding.
 
                                       20

<PAGE>
    In addition, an individual Non-United  States Holder who holds Common  Stock
would  generally be subject to tax  at a 30% rate on  any gain recognized on the
disposition of such  Common Stock if  such individual is  present in the  United
States  for 183 days or  more in the taxable year  of disposition and either (i)
has a "tax home" in the United  States (as specifically defined for purposes  of
the United States federal income tax) or (ii) maintains an office or other fixed
place of business in the United States and the income from the sale of the stock
is attributable to such office or other fixed place of business. Individual Non-
United  States Holders  may also  be subject  to tax  pursuant to  provisions of
United States  federal  income  tax  law applicable  to  certain  United  States
expatriates.
 
    Also,  special rules apply to Non-United States Holders if the Company is or
becomes a "United States  real property holding  corporation" for United  States
federal  income tax purposes. The Company believes  that it has not been, is not
currently, and is not  likely to become, a  United States real property  holding
corporation.  If  the  Company  were  a  United  States  real  property  holding
corporation, gain or loss on a sale of the Common Stock by any Non-United States
Holder (other than, in most cases, a Non-United States Holder that owns or owned
(directly or constructively) 5% or less of the Common Stock during the five-year
period ending on the date of such  sale) would be treated as income  effectively
connected  with the conduct of  a trade or business  within the United States by
the holder and subject to the net income tax described above.
 
UNITED STATES FEDERAL ESTATE TAXES
 
    Common Stock owned or treated as owned by an individual who is not a citizen
or resident (as specially defined for United States federal estate tax purposes)
of the United States at  the date of death, or  Common Stock subject to  certain
lifetime  transfers  made  by  such  an individual,  will  be  included  in such
individual's estate for  United States federal  estate tax purposes  and may  be
subject  to United  States federal estate  tax, unless an  applicable estate tax
treaty provides otherwise. Estates of nonresident aliens are generally allowed a
credit that is equivalent to an exclusion  of $60,000 of assets from the  estate
for United States federal estate tax purposes.
 
INFORMATION REPORTING AND BACKUP WITHHOLDING
 
    The  Company  must report  annually to  the Service  and to  each Non-United
States Holder the amount of dividends paid to, and the tax withheld with respect
to, such  holder, regardless  of whether  any tax  was actually  withheld.  That
information  may also be made available to the tax authorities of the country in
which a Non-United States Holder resides.
 
    United States federal backup withholding  tax (which, generally, is  imposed
at  the rate of 31% on certain payments to persons not otherwise exempt who fail
to furnish  information  required  under  United  States  information  reporting
requirements)  generally will not apply to dividends paid to a Non-United States
Holder either at an address outside  the United States (provided that the  payor
does  not have actual knowledge that the payee  is a United States person) or if
the dividends are subject to withholding at the 30% rate (or lower treaty rate).
As a general matter, information reporting and backup withholding also will  not
apply to a payment of the proceeds of a sale of Common Stock by a foreign office
of  a  broker.  However,  information  reporting  requirements  (but  not backup
withholding) will apply to a payment of  the proceeds of a sale of Common  Stock
by  a foreign office of a broker that is a United States person, or by a foreign
office of a  foreign broker that  derives 50% or  more of its  gross income  for
certain periods from the conduct of a trade or business in the United States, or
that  is a "controlled foreign corporation" as  to the United States, unless the
broker has documentary evidence in its  records that the holder is a  Non-United
States   Holder  and  certain  conditions  are  met,  or  the  holder  otherwise
establishes an exemption. Payment by a United  States office of a broker of  the
proceeds  of a sale  of Common Stock  is subject to  both backup withholding and
information reporting unless the  holder certifies as  to its non-United  States
status under penalties of perjury or otherwise establishes an exemption (and the
broker  has no actual knowledge to the  contrary.) The backup withholding tax is
not an additional tax and may be credited against the Non-United States Holder's
United States federal  income tax  liability or  refunded to  the extent  excess
amounts  are withheld, provided that the required information is supplied to the
Service.

    The U.S. Underwriting Agreement  provides that the  obligations of the  U.S.
Underwriters  are  subject to  certain conditions  precedent  and that  the U.S.
Underwriters will be obligated to purchase all of the U.S. Shares offered hereby
(other than those shares covered by the overallotment option described below) if
any are purchased. The U.S. Underwriting  Agreement provides that, in the  event
of  a  default by  a  U.S. Underwriter,  in  certain circumstances  the purchase
commitments of non-defaulting  U.S. Underwriters  may be increased  or the  U.S.
Underwriting Agreement may be terminated.
 
    The  Company has  entered into  a Subscription  Agreement (the "Subscription
Agreement") with the  Managers of  the International  Offering (the  "Managers")
providing  for the concurrent offer and sale of the International Shares outside
the United States and Canada. The closing of the U.S. Offering is a condition to
the closing of the International Offering and vice versa.
 
    The Company has granted to the U.S. Underwriters and the Managers an option,
exercisable by CS First Boston Corporation, expiring at the close of business on
the thirtieth (30th) day after  the date of this  Prospectus, to purchase up  to
1,050,000  additional  shares at  the initial  public  offering price,  less the
underwriting discounts or  commissions, all as  set forth on  the cover page  of
this  Prospectus. Such option may be  exercised only to cover over-allotments in
the sale of the Common Stock offered  hereby. To the extent that this option  to
purchase  is  exercised,  each U.S.  Underwriter  and each  Manager  will become
obligated, subject to  certain conditions,  to purchase  approximately the  same
percentage  of additional  shares being  sold to  the U.S.  Underwriters and the
Managers as the number of U.S. Shares set forth next to such U.S.  Underwriter's
name  in the preceding table and as the number of International Shares set forth
next to  such  Manager's name  in  the  corresponding table  in  the  prospectus
relating  to the International Offering bears to  the sum of the total number of
shares of Common Stock in such tables.
 
    The  Company  has  been  advised  by  the  Representatives  that  the   U.S.
Underwriters propose to offer the U.S. Shares to the public in the United States
and  Canada initially at the offering price set  forth on the cover page of this
Prospectus and, through the  Representatives, to certain  dealers at such  price
less  a concession of $           per share, and  the U.S. Underwriters and such
dealers may allow a discount of $           per share on sales to certain  other
dealers.  After  the  initial public  offering,  the public  offering  price and
concession and discount to dealers may be changed by the Representatives.
 
    The public  offering  price and  the  aggregate underwriting  discounts  and
commissions  per share and per share concession  and discount to dealers for the
U.S. Offering  and  the concurrent  International  Offering will  be  identical.
Pursuant  to an  Agreement between the  U.S. Underwriters and  the Managers (the
"Intersyndicate Agreement") relating  to the  Offerings, changes  in the  public
offering price, concession and discount to dealers will be made only upon mutual
agreement  of  CS  First  Boston  Corporation,  as  representative  of  the U.S.
Underwriters, and CS First Boston Limited ("CSFBL") on behalf of the Managers.

    Pursuant to the Intersyndicate Agreement, each of the U.S. Underwriters  has
agreed  that, as  part of  the distribution  of the  U.S. Shares  and subject to
certain exceptions, it  has not offered  or sold,  and will not  offer or  sell,
directly  or indirectly, any shares of Common Stock or distribute any prospectus
relating to the Common Stock to any  person outside the United States or  Canada
or to any other dealer who does not so agree. Each of the Managers has agreed or
will  agree that, as  part of the  distribution of the  International Shares and
subject to certain exceptions, it has not offered or sold, and will not offer or
sell, directly  or indirectly,  any shares  of Common  Stock or  distribute  any
prospectus relating to the Common Stock in the United States or Canada or to any
dealer  who  does  not so  agree.  The  foregoing limitations  do  not  apply to
stabilization transactions or to transactions between the U.S. Underwriters  and
the  Managers pursuant to the Intersyndicate  Agreement. As used herein, "United
States" means  the  United States  of  America  (including the  States  and  the
District  of Columbia), its territories, possessions  and other areas subject to
its jurisdiction, "Canada" means Canada, its provinces, territories, possessions
and other areas subject to  its jurisdiction, and an offer  or sale shall be  in
the  United States or Canada if it is made to (i) any individual resident of the
United  States  or  Canada  or  (ii)  any  corporation,  partnership,   pension,
profit-sharing  or other trust or other entity (including any such entity acting
as an  investment  advisor  with  discretionary  authority)  whose  office  most
directly involved with the purchase is located in the United States or Canada.
 
    Pursuant to the Intersyndicate Agreement, sales may be made between the U.S.
Underwriters and the Managers of such number of shares of Common Stock as may be
mutually  agreed  upon. The  price  of any  shares so  sold  will be  the public
offering price, less  such amount as  may be  mutually agreed upon  by CS  First
Boston  Corporation, as representative  of the U.S.  Underwriters, and CSFBL, on
behalf of the Managers, but such  amount will not exceed the selling  concession
applicable  to  such shares.  To the  extent  there are  sales between  the U.S.
Underwriters and  the Managers  pursuant to  the Intersyndicate  Agreement,  the
number  of  shares of  Common Stock  initially  available for  sale by  the U.S.
Underwriters or by the Managers may be more or less than the amount appearing on
the cover  page  of this  Prospectus.  Neither  the U.S.  Underwriters  nor  the
Managers  are obligated to purchase  from the other any  unsold shares of Common
Stock.
 
    The Company  has agreed  that it  will not  offer, sell,  contract to  sell,
announce,  its intention  to sell, pledge  or otherwise dispose  of, directly or
indirectly, or file with the  Securities and Exchange Commission a  registration
statement  under the Securities Act of  1933 (the "Securities Act") relating to,
any additional shares  of its  Common Stock  or securities  convertible into  or
exchangeable or exercisable for any shares of its Common Stock without the prior
written consent of CS First Boston Corporation for a period of 90 days after the
date  of this  Prospectus, except  for issuances and  sales of  shares of Common
Stock in accordance  with the  terms of any  employee or  director stock  option
plan,  stock  ownership  plan,  stock bonus  plan,  stock  compensation  plan or
dividend reinvestment plan  of the  Company as  in effect  on the  date of  this
Prospectus.
 
    The  Company has agreed to indemnify  the U.S. Underwriters and the Managers
against certain liabilities,  including civil liabilities  under the  Securities
Act,  or to contribute to  payments that the U.S.  Underwriters and the Managers
may be required to make in respect thereof.
 
    Certain of the U.S. Underwriters and Managers and their affiliates have from
time to time performed, and continue to perform, various investment banking  and
commercial  banking services for  the Company, for  which customary compensation
has been received.

RESALE RESTRICTIONS
 
    The distribution of  the Common  Stock in  Canada is  being made  only on  a
private placement basis exempt from the requirement that the Company prepare and
file  a prospectus with  the securities regulatory  authorities in each province
where trades of the  Common Stock are effected.  Accordingly, any resale of  the
Common  Stock in  Canada must be  made in accordance  with applicable securities
laws which  will vary  depending on  the relevant  jurisdiction, and  which  may
require  resales to be made in accordance with available statutory exemptions or
pursuant to  a  discretionary  exemption  granted  by  the  applicable  Canadian
securities  regulatory authority.  Purchasers are  advised to  seek legal advice
prior to any resale of the Common Stock.
 
REPRESENTATIONS OF PURCHASERS
 
    Each  purchaser  of  Common  Stock   in  Canada  who  receives  a   purchase
confirmation will be deemed to represent to the Company and the dealer from whom
such purchase confirmation is received that (i) such purchaser is entitled under
applicable  provincial securities laws to purchase such Common Stock without the
benefit of  a  prospectus  qualified  under such  securities  laws,  (ii)  where
required  by law,  that such  purchaser is  purchasing as  principal and  not as
agent, and  (iii) such  purchaser  has reviewed  the  text above  under  "Resale
Restrictions."
 
RIGHTS OF ACTION AND ENFORCEMENT
 
    The  securities  being offered  are those  of a  foreign issuer  and Ontario
purchasers will  not  receive the  contractual  right of  action  prescribed  by
section  32 of the Regulation  under the Securities Act  (Ontario). As a result,
Ontario purchasers must rely on other remedies that may be available,  including
common  law rights of action for damages or rescission or rights of action under
the civil liability provisions of the U.S. federal securities laws.
 
    All of the  issuer's directors  and officers as  well as  the experts  named
herein may be located outside of Canada and, as a result, it may not be possible
for  Ontario  purchasers to  effect service  of process  within Canada  upon the
issuer or such persons. All or a substantial portion of the assets of the issuer
and such persons may be located outside of  Canada and, as a result, it may  not
be  possible to satisfy a judgment against  the issuer or such persons in Canada
or to enforce  a judgment  obtained in Canadian  courts against  such issuer  or
persons outside of Canada.

Such  report  must  be  in  the form  attached  to  British  Columbia Securities
Commission Blanket Order BOR #95/17,  a copy of which  may be obtained from  the
Company. Only one such report must be filed in respect of shares of Common Stock

    The Subscription Agreement provides that the obligations of the Managers are
such that,  subject  to  certain  conditions precedent,  the  Managers  will  be
obligated to purchase all of the International Shares offered hereby (other than
those  shares covered by the  over allotment option described  below) if any are
purchased. The Subscription Agreement provides that,  in the event of a  default
by   a   Manager,  in   certain  circumstances   the  purchase   commitments  of
non-defaulting Managers may be  increased or the  Subscription Agreement may  be
terminated.
 
    The  Company has entered  into an Underwriting  Agreement (the "Underwriting
Agreement")  with  the  U.S.  Underwriters  of  the  U.S.  Offering  (the  "U.S.
Underwriters") providing for the concurrent offer and sale of the U.S. Shares in
the United States and Canada. The closing of the U.S. Offering is a condition to
the closing of the International Offering and vice versa.
 
    The Company has granted to the Managers and the U.S. Underwriters an option,
exercisable by CS First Boston Corporation, expiring at the close of business on
the  thirtieth (30th) day after  the date of this  Prospectus, to purchase up to
1,050,000 additional  shares, at  the initial  public offering  price, less  the
underwriting  discounts or commissions,  all as set  forth on the  cover page of
this Prospectus. Such option may be  exercised only to cover over-allotments  in
the  sale of the shares of Common Stock  offered hereby. To the extent that this
option to purchase is exercised, each  Manager and U.S. Underwriter will  become
obligated,  subject to  certain conditions,  to purchase  approximately the same
percentage of  additional  shares  being  sold to  the  Managers  and  the  U.S.
Underwriters  as  the number  of  International Shares  set  forth next  to such
Manager's name in the preceding table and as the number of U.S. Shares set forth
next to  such  U.S.  Underwriter's  name  in  the  corresponding  table  in  the
prospectus relating to the U.S. Offering bears to the sum of the total number of
shares of Common Stock in such tables.
 
    The Company has been advised by CS First Boston Limited ("CSFBL"), on behalf
of  the Managers,  that the Managers  propose to offer  the International Shares
outside the United States and Canada initially at the public offering price  set
forth on the cover page of this Prospectus and, through the Managers, to certain
dealers at such price less a commission of $         per share, and the Managers
and  such dealers may  allow a commission of  $           per  share on sales to
certain other dealers. After  the initial public  offering, the public  offering
price and commission and reallowance may be changed by the Managers.
 
    The  offering price and the aggregate underwriting discounts and commissions
per  share  and  per  share  commission  and  reallowance  to  dealers  for  the
International  Offering  and the  concurrent  U.S. Offering  will  be identical.
Pursuant to an  Agreement between the  U.S. Underwriters and  the Managers  (the
"Intersyndicate  Agreement") relating to the  Offerings, changes in the offering
price, the aggregate Underwriting  discounts and commissions  per share and  per
share  commission  and reallowance  to dealers,  will be  made only  upon mutual
agreement of CSFBL, on behalf of  the Managers, and CS First Boston  Corporation
on behalf of the U.S. Underwriters.
 

<PAGE>
    Pursuant  to the Intersyndicate  Agreement, each of  the Managers has agreed
that, as part  of the distribution  of the International  Shares and subject  to
certain  exceptions, it  has not offered  or sold,  and will not  offer or sell,
directly or indirectly, any shares of Common Stock or distribute any  prospectus
relating  to the Common Stock to any person in the United States or Canada or to
any other dealer who does not so agree. Each of the U.S. Underwriters has agreed
that, as part  of the distribution  of the  U.S. Shares and  subject to  certain
exceptions,  it has not offered or sold, and will not offer or sell, directly or
indirectly, any shares of Common Stock or distribute any prospectus relating  to
the  Common Stock to  any person outside the  United States or  Canada or to any
dealer who  does  not  so agree.  The  foregoing  limitations do  not  apply  to
stabilization  transactions or to transactions between the Managers and the U.S.
Underwriters pursuant to the Intersyndicate  Agreement. As used herein,  "United
States"  means  the  United States  of  America  (including the  States  and the
District of Columbia), its territories  and possessions and other areas  subject
to  its  jurisdiction, "Canada"  means  Canada, its  provinces,  territories and
possessions and other areas  subject to its jurisdiction,  and an offer or  sale
shall  be in the  United States or  Canada if it  is made to  (i) any individual
resident of the United  States or Canada or  (ii) any corporation,  partnership,
pension,  profit-sharing  or other  trust or  other  entity (including  any such
entity acting  as  an investment  advisor  with discretionary  authority)  whose
office  most directly involved with the purchase is located in the United States
or Canada.
 
    Pursuant to  the Intersyndicate  Agreement, sales  may be  made between  the
Managers  and the U.S. Underwriters of such  number of shares of Common Stock as
may be mutually agreed  upon. The price  of any shares of  Common Stock so  sold
will  be the  public offering price  less such  amount agreed upon  by CSFBL, on
behalf of the Managers, and C.S. First Boston Corporation, as representative  of
the  U.S. Underwriters, but  such amount will not  exceed the selling concession
applicable to such shares.  To the extent there  are sales between the  Managers
and  the U.S. Underwriters pursuant to  the Intersyndicate Agreement, the number
of shares of Common Stock initially available for sale by the Managers or by the
U.S. Underwriters may be  more or less  than the amount  appearing on the  cover
page  of this  Prospectus. Neither  the Managers  nor the  U.S. Underwriters are
obligated to purchase from the other any unsold shares of Common Stock.
 
    Each of  the Managers  and the  U.S. Underwriters  severally represents  and
agrees  that (1) it has not offered or sold,  and will not offer or sell, in the
United Kingdom, by means of any document, any shares of Common Stock other  than
to  persons whose ordinary business  it is to buy  or sell shares or debentures,
whether as a principal or agent, or in circumstances which do not constitute  an
offer  to the public  within the meaning of  the Companies Act  1985, (2) it has
complied and  will  comply  with  all applicable  provisions  of  the  Financial
Services  Act of  1986 with respect  to anything done  by it in  relation to any
shares of Common Stock in, from  or otherwise involving the United Kingdom,  and
(3) it has only issued or passed on and will only issue or pass on to any person
in  the United Kingdom any document received  by it in connection with the issue
of any shares of Common  Stock if the person is  of a kind described in  Article
9(3) of the Financial Services Act 1986 (Investment Advertisements) (Exemptions)
Order  1988 or is a person to whom the document may otherwise lawfully be issued
or passed on.
 
    The Company  has agreed  that it  will not  offer, sell,  contract to  sell,
announce  its intention  to sell,  pledge or  otherwise dispose  of, directly or
indirectly, or file with the  Securities and Exchange Commission a  registration
statement  under the Securities Act of  1933 (the "Securities Act") relating to,
any additional shares  of its  Common Stock  or securities  convertible into  or
exchangeable or exercisable for any shares of its Common Stock without the prior
written consent of CS First Boston Corporation for a period of 90 days after the
date  of this  Prospectus, except  for issuances and  sales of  shares of Common
Stock in accordance  with the  terms of any  employee or  director stock  option
plan,  stock  ownership  plan,  stock bonus  plan,  stock  compensation  plan or
dividend reinvestment plan  of the  Company as  in effect  on the  date of  this
Prospectus.
 
    The  Company has agreed to indemnify  the Managers and the U.S. Underwriters
against certain liabilities,  including civil liabilities  under the  Securities
Act,  or to contribute to  payments that the Managers  and the U.S. Underwriters
may be required to make in respect thereof.
 
    Certain of the Managers and U.S. Underwriters and their affiliates have from
time to time performed, and continue to perform, various investment banking  and
commercial  banking services for  the Company, for  which customary compensation
has been received.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    Section 145 of the Delaware General Corporation Law (the "Act"), and Article
V of  the  Company's Bylaws  relate  to  the indemnification  of  the  Company's
directors  and officers,  among others,  in a  variety of  circumstances against
liabilities arising in connection with the performance of their duties.
 
    The Act permits  indemnification of  directors and officers  acting in  good
faith  and in a  manner they reasonably believe  to be in or  not opposed to the
best interests  of the  Company or  its  shareholders (and,  with respect  to  a
criminal  proceeding, if they have no  reasonable cause to believe their conduct
to be unlawful)  against (i)  expenses (including  attorney's fees),  judgments,
penalties, fines and amounts paid in settlement actually and reasonably incurred
in  connection  with  any  threatened, pending  or  completed  action,  suit, or
proceeding (other than an action by or in the right of the Company) arising  out
of  a position  with the  Company (or  with some  other entity  at the Company's
request) and  (ii) expenses  (including  attorneys' fees)  and amounts  paid  in
settlement  actually and  reasonably incurred  in connection  with a threatened,
pending, or completed action or suit by  or in the right of the Company,  unless
the  director or officer is found liable to the Company and an appropriate court
does not determine that he or she is nevertheless fairly and reasonably entitled
to indemnification.
 
    The Act requires indemnification for expenses to the extent that a  director
or  officer is successful  on the merits  in defending against  any such action,
suit or proceeding, and otherwise  requires in general that the  indemnification
provided for in (i) and (ii) above be made only on a determination by a majority
vote of a quorum of the Board of Directors who were not parties or threatened to
be  made parties to  the action, suit or  proceeding, or, if  a quorum cannot be
obtained, (a)  by independent  legal counsel,  or (b)  by the  shareholders.  In
certain  circumstances, the Act further permits  advances to cover such expenses
before a final determination that  indemnification is permissible, upon  receipt
of  a written undertaking  by or on behalf  of the director  or officer to repay
such amounts if it shall ultimately be determined that they are not entitled  to
indemnification.
 
    Indemnification   under  the  Act  is  not  exclusive  of  other  rights  to
indemnification  to  which  a  person  may  be  entitled  under  the   Company's
Certificate of Incorporation, Bylaws or a contractual agreement. The Act permits
the  Company  to purchase  insurance  on behalf  of  its directors  and officers
against liabilities arising out of their  positions with the Company whether  or
not such liabilities would be within the foregoing indemnification provisions.
 
    Under  the Company's Bylaws, the Company is required to indemnify any person
who was or is  a party or is  threatened to be made  a party to any  threatened,
pending or completed action, suit or proceeding, whether
 
                                      II-1

<PAGE>
civil,  criminal, administrative or investigative (other than an action by or in
the right  of the  Company, a  "derivative action")  and any  appeal thereof  by
reason  of the fact that such  person is, was or agreed  to become a director or
officer of the Company, against expenses (including attorneys' fees), judgments,
penalties, fines and amounts paid in settlement actually and reasonably incurred
by such person in connection with such action, suit or proceeding to the fullest
extent allowed under Delaware or other  applicable state law. The Company  shall
indemnify  an indemnitee  in connection with  a suit brought  by such indemnitee
only if the proceeding was authorized by the Company or is instituted to enforce
the indemnification  rights herein  above  mentioned. The  Company may  pay  the
expenses (including attorney's fees) incurred by any officer, director, employee
or  agent who is interviewed,  subpoenaed or deposed as  a witness, or otherwise
incurs expenses,  in  connection  with  any  action  or  proceeding,  if  it  is
determined that such payments will benefit the Company.
 
    The  Company's Bylaws  provide that the  Company shall pay  for the expenses
incurred by  an indemnified  director or  officer in  defending the  proceedings
specified above, in advance of their final disposition, provided that the person
furnishes  the Company  with an  undertaking to reimburse  the Company  if it is
ultimately determined that such person  is not entitled to indemnification.  The
Company  may provide indemnification at the discretion of the Board of Directors
and on such terms and under such conditions as the Board shall deem  appropriate
to  any person who is or  was serving as an employee  or agent. In addition, the
Company may purchase and maintain  insurance on behalf of  any person who is  or
was  a director, officer, employee or agent of the Company (or is serving or was
serving at the request of an executive officer the Company in such a position at
a related entity) against  any liability asserted against  and incurred by  such
person  in such capacity, or arising out  of the person's status as such whether
or not the  Company would have  the power  or the obligation  to indemnify  such
person against such liability under the provisions of the Company's Bylaws.
 
    The  Company has entered  into an agreement  with each of  its directors and
certain of its officers indemnifying them to the fullest extent permitted by the
foregoing. The  Company  has  also  purchased  director  and  officer  liability
insurance.  Reference  is  made  to  the  forms  of  Underwriting  Agreement and
Subscription Agreement  filed as  Exhibits 1.1  and 1.2,  respectively, to  this
Registration  Statement for certain provisions  regarding the indemnification of
officers and directors of the Company by the U.S. Underwriters and Managers.

ITEM 17.  UNDERTAKINGS
 
    The undersigned registrant hereby undertakes that:
 
        (a) 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;
 
        (b)  insofar  as  indemnification  for  liabilities  arising  under  the
    Securities  Act  of  1933  may  be  permitted  to  directors,  officers  and
    controlling  persons of the registrant  pursuant to the provisions described
    under Item 15 above, or otherwise,  the registrant has been advised that  in
    the  opinion of the Securities  and Exchange Commission such indemnification
    is against  public  policy as  expressed  in  such 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 such Act and
    will be governed by the final adjudication of such issue;
 
        (c) for purposes of determining  any liability under the Securities  Act
    of  1933, the information omitted from the  form of prospectus filed as part
    of this registration statement in reliance upon Rule 430A and contained in a
    form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4)
    or 497(h)  under the  Securities Act  shall be  deemed to  be part  of  this
    registration statement as of the time it was declared effective; and
 
        (d)  for purposes of determining any  liability under the Securities Act
    of 1933, each post-effective  amendment that contains  a form of  prospectus
    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.

     The Company hereby agrees with the several Underwriters as follows:

     2.  REPRESENTATIONS AND WARRANTIES OF THE COMPANY.  The Company represents
and warrants to, and agrees with, the several Underwriters that:


                                     Exhibit 1.1




<PAGE>

          (a)  A registration statement (No. 333-_______) relating to the 
     Offered Securities, including a form of prospectus relating to the U.S. 
     Securities and a form of prospectus relating to the International 
     Securities being offered in the International Offering, has been filed 
     with the Securities and Exchange Commission (the "Commission") and either 
     (i) has been declared effective under the Securities Act of 1933 (the 
     "Act") and is not proposed to be amended or (ii) is proposed to be 
     amended by amendment or post-effective amendment.  If such registration 
     statement (the "initial registration statement") has been declared 
     effective, either (A) an additional registration statement (the 
     "additional registration statement") relating to the Offered Securities 
     may have been filed with the Commission pursuant to Rule 462(b) 
     ("Rule 462(b)") under the Act and, if so filed, has become effective 
     upon filing pursuant to such Rule and the Offered Securities all have 
     been duly registered under the Act pursuant to the initial registration 
     statement and, if applicable, the additional registration statement or 
     (B) such an additional registration statement is proposed to be filed 
     with the Commission pursuant to Rule 462(b) and will become effective 
     upon filing pursuant to such Rule and upon such filing the Offered 
     Securities will all have been duly registered under the Act pursuant 
     to the initial registration statement and such additional registration 
     statement.  If the Company does not propose to amend the initial 
     registration statement or if an additional registration statement
     has been filed and the Company does not propose to amend it, and if any
     post-effective amendment to either such registration statement has been
     filed with the Commission prior to the execution and delivery of this
     Agreement, the most recent amendment (if any) to each such registration
     statement has been declared effective by the Commission or has become
     effective upon filing pursuant to Rule 462(c) ("Rule 462(c)") under the Act
     or, in the case of the additional registration statement, Rule 462(b).  For
     purposes of this Agreement, "Effective Time" with respect to the initial
     registration statement or, if filed prior to the execution and delivery of
     this Agreement, the additional registration statement means (i) if the
     Company has advised the Representatives that it does not propose to amend
     such registration statement, the date and time as of which such
     registration statement, or the most recent post-effective amendment thereto
     (if any) filed prior to the execution and delivery of this Agreement, was
     declared effective by the Commission or has become effective upon filing
     pursuant to Rule 462(c), or (ii) if the Company has advised the
     Representatives that it proposes to file an amendment or post-effective
     amendment to such registration statement, the date and time as of which
     such registration statement, as amended by such amendment or post-effective
     amendment, as the case may be, is declared effective by the Commission.  If
     an additional registration statement has not been filed prior to the
     execution and delivery of this Agreement but the Company has advised the
     Representatives that it proposes to file one, "Effective Time" with respect
     to such additional registration statement means the date and time as of
     which such registration statement is filed and becomes effective pursuant
     to Rule 462(b). "Effective Date" with respect to the initial registration
     statement or the additional registration statement (if any) means the date
     of the Effective Time thereof.  The initial registration statement, as
     amended at its Effective Time, including all material incorporated by
     reference therein, including all information contained in the additional
     registration statement (if any) and deemed to be a part of the initial
     registration statement as of the Effective Time of the additional
     registration statement pursuant to the General Instructions of the Form on
     which it is filed and including all information (if any) deemed to be a
     part of the initial registration statement as of its Effective Time
     pursuant to Rule 430A(b) ("Rule 430A(b)") under the Act, is hereinafter
     referred to as the "Initial Registration Statement."  The additional
     registration statement, as amended at its Effective Time, including the
     contents of the Initial Registration Statement incorporated by reference
     therein and including all information (if any) deemed to be a part of the
     additional registration statement as of its Effective Time pursuant to Rule
     430A(b), is hereinafter referred to as the "Additional Registration
     Statement."  The Initial Registration Statement and the Additional
     Registration Statement are hereinafter

                                        2


<PAGE>

     referred to collectively as the "Registration Statements" and individually
     as a "Registration Statement."  The form of prospectus relating to the U.S.
     Securities and the form of prospectus relating to the International
     Securities, each as first filed with the Commission pursuant to and in
     accordance with Rule 424(b) ("Rule 424(b)") under the Act or (if no such
     filing is required) as included in the Registration Statement, including
     all material incorporated by reference in each such prospectus, are
     hereinafter referred to as the "U.S. Prospectus" and the "International
     Prospectus," respectively, and collectively as the "Prospectuses."  No
     document has been or will be prepared or distributed in reliance on
     Rule 434 under the Act.

          (b)  If the Effective Time of the Initial Registration Statement is
     prior to the execution and delivery of this Agreement:  (i) on the
     Effective Date of the Initial Registration Statement, the Initial
     Registration Statement conformed in all respects to the requirements of the
     Act and the rules and regulations of the Commission (the "Rules and
     Regulations") and did not include any untrue statement of a material fact
     or omit to state any material fact required to be stated therein or
     necessary to make the statements therein not misleading, (ii) on the
     Effective Date of the Additional Registration Statement (if any), each
     Registration Statement conformed, or will conform, in all respects to the
     requirements of the Act and the Rules and Regulations and did not include,
     or will not include, any untrue statement of a material fact and did not
     omit, or will not omit, to state any material fact required to be stated
     therein or necessary to make the statements therein not misleading, and
     (iii) on the date of this Agreement, the Initial Registration Statement
     and, if the Effective Time of the Additional Registration Statement is
     prior to the execution and delivery of this Agreement, the Additional
     Registration Statement each conforms, and at the time of filing of each of
     the Prospectuses pursuant to Rule 424(b) or (if no such filing is required)
     at the Effective Date of the Additional Registration Statement in which the
     Prospectuses are included, each Registration Statement and each of the
     Prospectuses will conform, in all respects to the requirements of the Act
     and the Rules and Regulations, and none of such documents includes, or will
     include, any untrue statement of a material fact or omits, or will omit, to
     state any material fact required to be stated therein or necessary to make
     the statements therein not misleading.  If the Effective Time of the
     Initial Registration Statement is subsequent to the execution and delivery
     of this Agreement: on the Effective Date of the Initial Registration
     Statement, the Initial Registration Statement and each of the Prospectuses
     will conform in all respects to the requirements of the Act and the Rules
     and Regulations, none of such documents will include any untrue statement
     of a material fact or will omit to state any material fact required to be
     stated therein or necessary to make the statements therein not misleading,
     and no Additional Registration Statement has been or will be filed.  The
     two preceding sentences do not apply to statements in or omissions from a
     Registration Statement or either of the Prospectuses based upon written
     information furnished to the Company by any Underwriter through the
     Representatives or by any Manager through CSFBL specifically for use
     therein, it being understood and agreed that the only such information is
     that described as such in Section 7(b).

          (c) The Company has been duly incorporated and is an existing
     corporation in good standing under the laws of the state of Delaware, with
     power and authority (corporate and other) to own its properties and conduct
     its business as described in the Prospectuses; and the Company is duly
     qualified to do business as a foreign corporation in good standing in all
     other jurisdictions in which its ownership or lease of property or the
     conduct of its business requires such qualification, except where the
     failure to be so qualified would not, individually or in the aggregate,
     have a material adverse effect on the properties, business, results of
     operations, condition (financial or otherwise), affairs or prospects of the
     Company and its significant

                                        3


<PAGE>

     subsidiaries listed on Schedule B hereto (each a "Subsidiary" and,
     collectively, the "Subsidiaries"), taken as a whole (a "Material Adverse
     Effect").

          (d) Each Subsidiary of the Company has been duly incorporated and is
     an existing corporation in good standing under the laws of the jurisdiction
     of its incorporation, with power and authority (corporate and other) to own
     its properties and conduct its business as described in the Prospectuses;
     and each Subsidiary of the Company is duly qualified to do business as a
     foreign corporation in good standing in all other jurisdictions in which
     its ownership or lease of property or the conduct of its business requires
     such qualification, except where such failure would not, individually or in
     the aggregate, have a Material Adverse Effect; all of the issued and
     outstanding capital stock of each Subsidiary of the Company has been duly
     authorized and validly issued and is fully paid and nonassessable; and the
     capital stock of each Subsidiary owned by the Company, directly or through
     Subsidiaries, is owned free from liens, encumbrances and defects.

          (e) The Offered Securities and all other outstanding shares of capital
     stock of the Company have been duly authorized; all outstanding shares of
     capital stock of the Company are, and, when the Offered Securities have
     been delivered and paid for in accordance with this Agreement and the
     Subscription Agreement on each Closing Date (as defined below), such
     Offered Securities will have been, validly issued, fully paid and
     nonassessable and will conform to the description thereof contained in the
     Prospectuses; and the stockholders of the Company have no preemptive rights
     with respect to the Securities.

          (f) Except as disclosed in the Prospectuses, there are no contracts,
     agreements or understandings between the Company and any person that would
     give rise to a valid claim against the Company or any Underwriter or
     Manager for a brokerage commission, finder's fee or other like payment.

          (g) Other than the Registration Rights Agreement, dated as of March 1,
     1996 (the "Registration Rights Agreement"), by and among the Company, the
     Representatives and J.P. Morgan Securities Inc. related to the Company's 7%
     Notes Due 2006, 7 1/2% Debentures Due 2016 and 7 3/4% Debentures Due 2026,
     there are no contracts, agreements or understandings between the Company
     and any person granting such person the right to require the Company to
     file a registration statement under the Act with respect to any securities
     of the Company owned or to be owned by such person or to require the
     Company to include such securities in the securities registered pursuant to
     a Registration Statement or in any securities being registered pursuant to
     any other registration statement filed by the Company under the Act.

          (h) The Offered Securities have been approved for listing on The New
     York Stock Exchange and the Pacific Stock Exchange subject to notice of
     issuance.

          (i) No consent, approval, authorization, or order of, or filing with,

     States Department of Defense, or any court is required for the consummation
     of the transactions contemplated by this Agreement or the Subscription
     Agreement in connection with the issuance and sale of the Offered
     Securities by the Company, except such as have been obtained and made under
     the Act and such as may be required under state securities laws.

          (j) The execution, delivery and performance of this Agreement and the
     Subscription Agreement, and the issuance and sale of the Offered Securities
     will not result in a breach or

                                        4


<PAGE>

     violation of any of the terms and provisions of, or constitute a default
     under, (i) any statute, any rule, regulation or order of any governmental
     agency or body or any court, domestic or foreign, having jurisdiction over
     the Company or any Subsidiary of the Company or any of their properties, or
     any agreement or instrument to which the Company or any such Subsidiary is
     a party or by which the Company or any such Subsidiary is bound or to which
     any of the properties of the Company or any such Subsidiary is subject,
     except for any such breach, violation or default which would not have a
     Material Adverse Effect, or (ii) the charter or bylaws of the Company or
     any such Subsidiary, and the Company has full power and authority to
     authorize, issue and sell the Offered Securities as contemplated by this
     Agreement and the Subscription Agreement, respectively.

          (k) This Agreement and the Subscription Agreement have been duly
     authorized, executed and delivered by the Company.

          (l) Except as disclosed in the Prospectuses, the Company and its
     Subsidiaries have good and marketable title to all real properties and all
     other properties and assets owned by them, in each case free from liens,
     encumbrances and defects that would materially affect the value thereof or
     materially interfere with the use made or to be made thereof by them; and
     except as disclosed in the Prospectuses, the Company and its Subsidiaries
     hold any leased real or personal property under valid and enforceable
     leases with no exceptions that would materially interfere with the use made
     or to be made thereof by them.

          (m) The Company and its Subsidiaries possess adequate certificates,
     authorities or permits issued by appropriate governmental agencies or
     bodies necessary to conduct the business now operated by them and have not
     received any notice of proceedings relating to the revocation or
     modification of any such certificate, authority or permit that, if
     determined adversely to the Company or any of its Subsidiaries, would
     individually or in the aggregate have a Material Adverse Effect.

          (n) No labor dispute with the employees of the Company or any
     Subsidiary exists or, to the knowledge of the Company, is imminent that
     might have a Material Adverse Effect.

          (o) The Company and its Subsidiaries own, possess or can acquire on
     reasonable terms, adequate trademarks, trade names and other rights to
     inventions, know-how, patents, copyrights, confidential information and
     other intellectual property (collectively, "intellectual property rights")
     necessary to conduct the business now operated by them, or presently
     employed by them, and have not received any notice of infringement of or
     conflict with asserted rights of others with respect to any intellectual
     property rights that, if determined adversely to the Company or any of its
     Subsidiaries, would individually or in the aggregate have a Material
     Adverse Effect.

          (p) Except as disclosed in the Prospectuses, neither the Company nor
     any of its Subsidiaries is in violation of any statute, any rule,
     regulation, decision or order of any governmental agency or body or any
     court, domestic or foreign, relating to the use, disposal or release of
     hazardous or toxic substances or relating to the protection or restoration
     of the environment or human exposure to hazardous or toxic substances
     (collectively, "environmental laws"), owns or operates any real property
     contaminated with any substance that is subject to any environmental laws,
     is liable for any off-site disposal or contamination pursuant to any
     environmental laws, or is subject to any claim relating to any
     environmental laws, which violation, contamination, liability or claim
     would individually or in the aggregate have a

                                        5


<PAGE>

     Material Adverse Effect; and the Company is not aware of any pending
     investigation which might lead to such a claim.

          (q) Except as disclosed in the Prospectuses, there are no pending
     actions, suits or proceedings against or affecting the Company, any of its
     Subsidiaries or any of their respective properties that, if determined
     adversely to the Company or any of its subsidiaries, would individually or
     in the aggregate have a Material Adverse Effect or would materially and
     adversely affect the ability of the Company to perform its obligations
     under this Agreement or the Subscription Agreement, or which are otherwise
     material in the context of the sale of the Offered Securities; and no such
     actions, suits or proceedings are threatened or, to the Company's
     knowledge, contemplated.

          (r) The financial statements included in each Registration Statement
     and the Prospectuses present fairly the financial position of the Company
     and its consolidated subsidiaries as of the dates shown and their results
     of operations and cash flows for the periods shown, and such financial
     statements have been prepared in conformity with the generally accepted
     accounting principles in the United States applied on a consistent basis;
     the schedules included in each Registration Statement present fairly the
     information required to be stated therein; and the assumptions used in
     preparing the pro forma financial statements included in each Registration
     Statement and the Prospectus provide a reasonable basis for presenting the
     significant effects directly attributable to the transactions or events
     described therein, the related pro forma adjustments give appropriate
     effect to those assumptions, and the pro forma columns therein reflect the
     proper application of those adjustments to the corresponding historical
     financial statement amounts.

          (s) Except as disclosed in the Prospectuses, since the date of the
     latest audited financial statements included in the Prospectuses there has
     been no material adverse change, nor any development or event involving a
     prospective material adverse change, in the condition (financial or other),
     business, properties or results of operations of the Company and its
     Subsidiaries taken as a whole, and, except as disclosed in or contemplated
     by the Prospectuses, there has been no dividend or distribution of any kind
     declared, paid or made by the Company on any class of its capital stock.

          (t) The Company is not and, after giving effect to the offering and
     sale of the Offered Securities and the application of the proceeds thereof
     as described in the Prospectuses, will not be an "investment company" as
     defined in the Investment Company Act of 1940.

          (u) Neither the Company nor any of its affiliates does business with
     the government of Cuba or with any person or affiliate located in Cuba
     within the meaning of Section 517.075, Florida Statutes and the Company
     agrees to comply with such Section if prior to the completion of the
     distribution of the Offered Securities it commences doing such business.

     3.  PURCHASE, SALE AND DELIVERY OF OFFERED SECURITIES.  On the basis of the
representations, warranties and agreements herein contained, but subject to the
terms and conditions herein set forth, the Company agrees to sell to the
Underwriters, and the Underwriters agree, severally and not jointly, to purchase
from the Company, at a purchase price of U.S. $_______ per share, the respective
numbers of shares of U.S. Firm Securities set forth opposite the names of the
Underwriters in Schedule A hereto.

     The Company will deliver the U.S. Firm Securities to the Representatives
for the accounts of the Underwriters, at the office of CS First Boston
Corporation, Park Avenue Plaza, New York, NY

                                        6


<PAGE>

10055, against payment of the purchase price in funds available on the same day
by wire transfer to the account of the Company at a bank acceptable to CSFBC or
by official Federal Reserve Bank check or checks drawn to the order of the
Company at the office of Latham & Watkins, 633 W. Fifth Street, Suite 4000, Los
Angeles, CA 90071-2007, at 10:00 A.M., New York time, on May __, 1996, or at
such other time not later than seven full business days thereafter as CS First
Boston Corporation ("CSFBC") and the Company determine, such time being herein
referred to as the "First Closing Date."  For purposes of Rule 15c6-1 under the
Securities Exchange Act of 1934, the First Closing Date (if later than the
otherwise applicable settlement date) shall be the settlement date for payment
of funds and delivery of securities for all the Offered Securities sold pursuant
to the U.S. Offering and the International Offering.  The certificates for the
U.S. Firm Securities evidencing the U.S. Firm Securities so to be delivered will
be in definitive form, in such denominations and registered in such names as
CSFBC requests and will be made available for checking and packaging at the
office of CSFBC, at least 24 hours prior to the First Closing Date.

     In addition, upon written notice from CSFBC given to the Company from time
to time not more than 30 days subsequent to the date of the Prospectuses, the
Underwriters may purchase all or less than all of the U.S. Optional Securities
at the purchase price per Security to be paid for the U.S. Firm Securities.  The
U.S. Optional Securities to be purchased by the Underwriters on any Optional
Closing Date shall be in the same proportion to all the Optional Securities to
be purchased by the Underwriters and the Managers on such Optional Closing Date
as the U.S. Firm Securities bear to all the Firm Securities.  The Company agrees
to sell to the Underwriters such U.S. Optional Securities and the Underwriters
agree, severally and not jointly, to purchase such U.S. Optional Securities.
Such U.S. Optional Securities shall be purchased for the account of each
Underwriter in the same proportion as the number of shares of U.S. Firm
Securities set forth opposite such Underwriter's name bears to the total number
of shares of U.S. Firm Securities (subject to adjustment by CSFBC to eliminate
fractions) and may be purchased by the Underwriters only for the purpose of
covering over-allotments made in connection with the sale of the U.S. Firm
Securities.  No Optional Securities shall be sold or delivered unless the U.S.
Firm Securities and the International Firm Securities previously have been, or
simultaneously are, sold and delivered.  The right to purchase the Optional
Securities or any portion thereof may be exercised from time to time and to the
extent not previously exercised may be surrendered and terminated at any time
upon notice by CSFBC on behalf of Underwriters and the Managers to the Company.
It is understood that CSFBC is authorized to make payment for and accept
delivery of such Optional Securities on behalf of the Underwriters and Managers
pursuant to the terms of CSFBC's instructions to the Company.

     Each time for the delivery of and payment for the U.S. Optional Securities,
being herein referred to as an "Optional Closing Date," which may be the First
Closing Date (the First Closing Date and each Optional Closing Date, if any,
being sometimes referred to as a "Closing Date"), shall be determined by CSFBC
but shall be not later than five full business days after written notice of
election to purchase Optional Securities is given.  The Company will deliver the
U.S. Optional Securities being purchased on each Optional Closing Date to the
Representatives for the accounts of the several Underwriters, at the office of
CSFBC, against payment of the purchase price in funds available on the same day
by wire transfer to the account of the Company at a bank acceptable to CSFBC or
by official Federal Reserve Bank check or checks drawn to the order of the
Company, at the office of Latham & Watkins, 633 W. Fifth Street, Suite 4000, Los
Angeles, CA  90071-2007.  The certificates for the U.S. Optional Securities will
be in definitive fully registered form, in such denominations and registered in
such names as CSFBC requests upon reasonable notice prior to such Optional
Closing Date and will be made available for checking and packaging at the office
of CSFBC, at a reasonable time in advance of such Optional Closing Date.

     4.  OFFERING BY UNDERWRITERS.  It is understood that the several
Underwriters propose to offer the U.S. Securities for sale to the public as set
forth in the U.S. Prospectus.

     5.  CERTAIN AGREEMENTS OF THE COMPANY.  The Company agrees with the several
Underwriters that:

          (a)  If the Effective Time of the Initial Registration Statement is
     prior to the execution and delivery of this Agreement, the Company will
     file each of the Prospectuses with the Commission pursuant to and in
     accordance with subparagraph (1) (or, if applicable and if consented to by
     CSFBC, subparagraph (4)) of Rule 424(b) not later than the earlier of (A)
     the second business day following the execution and delivery of this
     Agreement or (B) the fifteenth business day after the Effective Date of the
     Initial Registration Statement.

          The Company will advise CSFBC promptly of any such filing pursuant to
     Rule 424(b). If the Effective Time of the Initial Registration Statement is
     prior to the execution and delivery of this Agreement and an additional
     registration statement is necessary to register a portion of the Offered
     Securities under the Act but the Effective Time thereof has not occurred as
     of such execution and delivery, the Company will file the additional
     registration statement or, if filed, will file a post-effective amendment
     thereto with the Commission pursuant to and in accordance with Rule 462(b)
     on or prior to 10:00 P.M., New York time, on the date of this Agreement or,
     if earlier, on or prior to the time either Prospectus is printed and
     distributed to any Underwriter or Manager, or will make such filing at such
     later date as shall have been consented to by CSFBC.

          (b)  The Company will advise CSFBC promptly of any proposal to amend
     or supplement the initial or any additional registration statement as filed
     or either of the related prospectuses or the Initial Registration
     Statement, the Additional Registration Statement (if any) or either of the
     Prospectuses and will not effect such amendment or supplementation without
     CSFBC's prior consent; and the Company will also advise CSFBC promptly of
     the effectiveness of each Registration Statement (if its Effective Time is
     subsequent to the execution and delivery of this Agreement) and of any
     amendment or supplementation of a Registration Statement or either of the
     Prospectuses and of the institution by the Commission of any stop order
     proceedings in respect of a Registration Statement and will use its best
     efforts to prevent the issuance of any such stop order and to obtain as
     soon as possible its lifting, if issued.

          (c)  If, at any time when a prospectus relating to the Offered
     Securities is required to be delivered under the Act in connection with
     sales by any Underwriter, Manager or dealer, any event occurs as a result
     of which either or both of the Prospectuses as then amended or supplemented
     would include an untrue statement of a material fact or omit to state any
     material fact necessary to make the statements therein, in the light of the
     circumstances under which they were made, not misleading, or if it is
     necessary at any time to amend either or both of the Prospectuses to comply
     with the Act, the Company will promptly notify CSFBC of such event and will
     promptly prepare and file with the Commission, at its own expense, an
     amendment or supplement which will correct such statement or omission or an
     amendment which will effect such compliance.  Neither CSFBC's consent to,
     nor the Underwriters' delivery of, any such amendment or supplement shall
     constitute a waiver of any of the conditions set forth in Section 6.

          (d)  As soon as practicable, but not later than the Availability Date
     (as defined below), the Company will make generally available to its
     security holders an earnings statement covering

                                        8


<PAGE>

     a period of at least 12 months beginning after the Effective Date of the
     Initial Registration Statement (or, if later, the Effective Date of the
     Additional Registration Statement) which will satisfy the provisions of
     Section 11(a) of the Act.  For the purpose of the preceding sentence,
     "Availability Date" means the 45th day after the end of the fourth fiscal
     quarter following the fiscal quarter that includes such Effective Date,
     except that, if such fourth fiscal quarter is the last quarter of the
     Company's fiscal year, "Availability Date" means the 90th day after the end
     of such fourth fiscal quarter.

          (e)  The Company will furnish to the Representatives copies of the
     Registration Statement (four of which will be signed and will include all
     exhibits), each preliminary prospectus relating to the U.S. Securities,
     and, so long as delivery of a prospectus relating to the Offered Securities
     is required to be delivered under the Act in connection with sales by any
     Underwriter or dealer, the U.S. Prospectus and all amendments and
     supplements to such documents, in each case in such quantities as CSFBC
     requests.  The U.S. Prospectus shall be so furnished on or prior to 3:00
     P.M., New York time, on the business day following the later of the
     execution and delivery of this Agreement or the Effective Time of the
     Initial Registration Statement.  All other such documents shall be so
     furnished as soon as available.  The Company will pay the expenses of
     printing and distributing to the Underwriters all such documents.

          (f)  The Company will arrange for the qualification of the Offered
     Securities for sale  under the laws of such jurisdictions in the
     United States as CSFBC designates and will continue such qualifications in
     effect so long as required for the distribution.

          (g)  During the period of five years hereafter, the Company will
     furnish to the Representatives and, upon request, to each of the other
     Underwriters, as soon as practicable after the end of each fiscal year, a
     copy of its annual report to stockholders for such year; and the Company
     will furnish to the Representatives (i) as soon as available, a copy of
     each report and any definitive proxy statement of the Company filed with
     the Commission under the Securities Exchange Act of 1934, as amended (the
     "Exchange Act"), or mailed to stockholders, and (ii) from time to time,
     such other information concerning the Company as CSFBC may reasonably
     request.

          (h)  The Company will pay all expenses incident to the performance of
     its obligations under this Agreement and will reimburse the Underwriters
     (if and to the extent incurred by them) for any filing fees and other
     expenses (including fees and disbursements of counsel) incurred by them in
     connection with qualification of the Offered Securities for sale under the
     laws of such jurisdictions in the United States as CSFBC designates and the
     printing of memoranda relating thereto, for the filing fee of the National
     Association of Securities Dealers, Inc. relating to the Offered Securities,
     for any travel expenses of the Company's officers and employees and any
     other expenses of the Company in connection with attending or hosting
     meetings with prospective purchasers of the Offered Securities and for
     expenses incurred in distributing preliminary prospectuses and the
     Prospectuses (including any amendments and supplements thereto) to the
     Underwriters.

          (i)  For a period of 90 days after the date of the initial public
     offering of the Offered Securities, the Company will not offer, sell,
     contract to sell, pledge or otherwise dispose of, directly or indirectly,
     or file with the Commission a registration statement under the Act relating
     to, any additional shares of its Securities or securities convertible into
     or exchangeable or exercisable for any shares of its Securities, or
     publicly disclose the intention to make any such offer, sale, pledge,
     disposal or filing, without the prior written consent of CSFBC, except

                                        9

     issuances of Securities pursuant to the conversion or exchange of
     convertible or exchangeable securities or the exercise of warrants or
     options, in each case outstanding on the date hereof, grants of employee
     stock options pursuant to the terms of a plan in effect on the date hereof,
     issuances of Securities pursuant to the exercise of such options or
     issuances of Securities pursuant to the Company's dividend reinvestment
     plan.

     6.  CONDITIONS OF THE OBLIGATIONS OF THE UNDERWRITERS.  The obligations of
the several Underwriters to purchase and pay for the U.S. Firm Securities on the
First Closing Date and the U.S. Optional Securities to be purchased on each
Optional Closing Date will be subject to the accuracy of the representations and
warranties on the part of the Company herein, to the accuracy of the statements
of Company officers made pursuant to the provisions hereof, to the performance
by the Company of its obligations hereunder and to the following additional
conditions precedent:

          (a)  The Representatives shall have received a letter, dated the date
     of delivery thereof (which, if the Effective Time of the Initial
     Registration Statement is prior to the execution and delivery of this
     Agreement, shall be on or prior to the date of this Agreement or, if the
     Effective Time of the Initial Registration Statement is subsequent to the
     execution and delivery of this Agreement, shall be prior to the filing of
     the amendment or post-effective amendment to the registration statement to
     be filed shortly prior to such Effective Time), of Deloitte & Touche LLP
     confirming that they are independent public accountants within the meaning
     of the Act and the applicable published Rules and Regulations thereunder
     and stating to the effect that:

               (i)  in their opinion the financial statements and schedules and
          summary of earnings examined by them and included in the Registration
          Statements comply as to form in all material respects with the
          applicable accounting requirements of the Act and the related
          published Rules and Regulations;

               (ii) they have performed the procedures specified by the American
          Institute of Certified Public Accountants for a review of interim
          financial information as described in Statement of Auditing Standards
          No. 71, Interim Financial Information, on the unaudited financial
          statements, if any, included in the Registration Statements;

               (iii) on the basis of the review referred to in clause (ii)
          above, a reading of the latest available interim financial statements
          of the Company, inquiries of officials of the Company who have
          responsibility for financial and accounting matters and other
          specified procedures, nothing came to their attention that caused them
          to believe that:

                    (A)  the unaudited financial statements and summary of
               earnings, if any, included in the Registration Statements do not
               comply as to form in all material respects with the applicable
               accounting requirements of the Act and the related published
               Rules and Regulations or any material modifications should be
               made to such unaudited financial statements and summary of
               earnings for them to be in conformity with generally accepted
               accounting principles;

                    (B)  the unaudited consolidated net sales, net income and
               net income per share amounts for the interim periods included in
               the Prospectuses, if any, do not agree with the amounts set forth
               in the unaudited consolidated financial statements for those same
               periods or were not determined on a basis

                                       10


<PAGE>

               substantially consistent with that of the corresponding amounts
               in the audited statements of income;

                    (C)  at the date of the latest available balance sheet read
               by such accountants, or at a subsequent specified date not more
               than five days prior to the date of this Agreement, there was any
               change in the capital stock or any increase in short-term
               indebtedness or long-term debt of the Company and its
               consolidated subsidiaries or, at the date of the latest available
               balance sheet read by such accountants, there was any decrease in
               consolidated net current assets or net assets, as compared with
               amounts shown on the latest balance sheet included in the
               Prospectuses; or

                    (D)  for the period from the closing date of the latest
               income statement included in the Prospectuses to the closing date
               of the latest available income statement read by such accountants
               there were any decreases, as compared with the corresponding
               period of the previous year and with the period of corresponding
               length ended the date of the latest income statement included in
               the Prospectuses, in consolidated net sales or in the total or
               per share amounts of consolidated income before extraordinary
               items or net income,

          except in all cases set forth in clauses (C) and (D) above for
          changes, increases or decreases which the Prospectuses disclose have
          occurred or may occur or which are described in such letter;

               (iv)  they have compared specified dollar amounts (or percentages
          derived from such dollar amounts) and other financial information
          contained in the Registration Statements (in each case to the extent
          that such dollar amounts, percentages and other financial information
          are derived from the general accounting records of the Company and its
          subsidiaries subject to the internal controls of the Company's
          accounting system or are derived directly from such records by
          analysis or computation) with the results obtained from inquiries, a
          reading of such general accounting records and other procedures
          specified in such letter and have found such dollar amounts,
          percentages and other financial information to be in agreement with
          such results, except as otherwise specified in such letter; and

               (v)  they have performed such other procedures as agreed upon by
          the Underwriters and disclosed the results of such procedures in such
          letter.

          For purposes of this subsection, (i) if the Effective Time of the
     Initial Registration Statement is subsequent to the execution and delivery
     of this Agreement, "Registration Statements" shall mean the initial
     registration statement as proposed to be amended by the amendment or post-
     effective amendment to be filed shortly prior to its Effective Time,
     (ii) if the Effective Time of the Initial Registration Statement is prior
     to the execution and delivery of this Agreement but the Effective Time of
     the Additional Registration is subsequent to such execution and delivery,
     "Registration Statements" shall mean the Initial Registration Statement and
     the additional registration statement as proposed to be filed or as
     proposed to be amended by the post-effective amendment to be filed shortly
     prior to its Effective Time, and (iii) "Prospectuses" shall mean the
     prospectuses included in the Registration Statements.  All financial
     statements

     and schedules included in material incorporated by reference into the
     Prospectuses shall be deemed included in the Registration Statements for
     purposes of this subsection.

          (b)  The Representatives shall have received a letter, dated the date
     of delivery thereof (which, if the Effective Time of the Initial
     Registration Statement is prior to the execution and delivery of this
     Agreement, shall be on or prior to the date of this Agreement or, if the
     Effective Time of the Initial Registration Statement is subsequent to the
     execution and delivery of this Agreement, shall be prior to the filing of
     the amendment or post-effective amendment to the registration statement to
     be filed shortly prior to such Effective Time), of Price Waterhouse LLP
     confirming that they are independent public accountants within the meaning
     of the Act and the applicable published Rules and Regulations thereunder
     and stating to the effect that:

               (i)  in their opinion the financial statements and schedules and
          summary of earnings of the Electronic Systems Group, formerly a
          business unit of Westinghouse Electric Corporation ("ESG"), examined
          by them and included in the Registration Statements comply as to form
          in all material respects with the applicable accounting requirements
          of the Act and the related published Rules and Regulations;

               (ii) they have performed the procedures specified by the American
          Institute of Certified Public Accountants for a review of interim
          financial information as described in Statement of Auditing Standards
          No. 71, Interim Financial Information, on the unaudited financial
          statements of ESG, if any, included in the Registration Statements;
          and

               (iii) on the basis of the review referred to in clause (ii)
          above, a reading of the latest available interim financial statements
          of ESG, inquiries of officials of ESG who have responsibility for
          financial and accounting matters and other specified procedures,
          nothing came to their attention that caused them to believe that:

                    (A)  the unaudited financial statements and summary of
               earnings of ESG, if any, included in the Registration Statements
               do not comply as to form in all material respects with the
               applicable accounting requirements of the Act and the related
               published Rules and Regulations or any material modifications
               should be made to such unaudited financial statements and summary
               of earnings for them to be in conformity with generally accepted
               accounting principles;

                    (B)  the unaudited consolidated net sales and net income of
               ESG for the interim periods included in the Prospectuses, if any,
               do not agree with the amounts set forth in the unaudited
               consolidated financial statements for those same periods or were
               not determined on a basis substantially consistent with that of
               the corresponding amounts in the audited statements of income;

                    (C)  at the date of the latest available balance sheet read
               by such accountants, or at a subsequent specified date not more
               than five days prior to the date of this Agreement, there was any
               change in the capital stock or any increase in short-term
               indebtedness or long-term debt of ESG or, at the date of the
               latest available balance sheet read by such accountants, there
               was any decrease in consolidated net current assets or net
               assets, as compared with amounts shown on the latest balance
               sheet included in the Prospectuses; or

                                       12


<PAGE>

                    (D)  for the period from the closing date of the latest
               income statement included in the Prospectuses to the closing date
               of the latest available income statement read by such accountants
               there were any decreases, as compared with the corresponding
               period of the previous year and with the period of corresponding
               length ended the date of the latest income statement included in
               the Prospectuses, in consolidated net sales or in the total or
               per share amounts of consolidated income before extraordinary
               items or net income,

          except in all cases set forth in clauses (C) and (D) above for
          changes, increases or decreases which the Prospectuses disclose have
          occurred or may occur or which are described in such letter.

          For purposes of this subsection, (i) if the Effective Time of the
     Initial Registration Statement is subsequent to the execution and delivery
     of this Agreement, "Registration Statements" shall mean the initial
     registration statement as proposed to be amended by the amendment or post-
     effective amendment to be filed shortly prior to its Effective Time,
     (ii) if the Effective Time of the Initial Registration Statement is prior
     to the execution and delivery of this Agreement but the Effective Time of
     the Additional Registration is subsequent to such execution and delivery,
     "Registration Statements" shall mean the Initial Registration Statement and
     the additional registration statement as proposed to be filed or as
     proposed to be amended by the post-effective amendment to be filed shortly
     prior to its Effective Time, and (iii) "Prospectuses" shall mean the
     prospectuses included in the Registration Statements.  All financial
     statements and schedules included in material incorporated by reference
     into the Prospectuses shall be deemed included in the Registration
     Statements for purposes of this subsection.

          (c)  If the Effective Time of the Initial Registration Statement is
     not prior to the execution and delivery of this Agreement, such Effective
     Time shall have occurred not later than 10:00 P.M., New York time, on the
     date of this Agreement or such later date as shall have been consented to
     by CSFBC.  If the Effective Time of the Additional Registration Statement
     (if any) is not prior to the execution and delivery of this Agreement, such
     Effective Time shall have occurred not later than 10:00 P.M., New York
     time, on the date of this Agreement or, if earlier, the time either
     Prospectus is printed and distributed to any Underwriter or Manager, or
     shall have occurred at such later date as shall have been consented to by
     CSFBC.  If the Effective Time of the Initial Registration Statement is
     prior to the execution and delivery of this Agreement, each of the
     Prospectuses shall have been filed with the Commission in accordance with
     the Rules and Regulations and Section 5(a) of this Agreement.  Prior to
     such Closing Date, no stop order suspending the effectiveness of a
     Registration Statement shall have been issued and no proceedings for that
     purpose shall have been instituted or, to the knowledge of the Company or
     the Representatives, shall be contemplated by the Commission.

          (d)  Subsequent to the execution and delivery of this Agreement, there
     shall not have occurred (i) any change, or any development or event
     involving a prospective change, in the condition (financial or other),
     business, properties or results of operations of the Company or its
     Subsidiaries which, in the judgment of a majority in interest of the
     Underwriters including the Representatives, is material and adverse and
     makes it impractical or inadvisable to proceed with completion of the
     public offering or the sale of and payment for the U.S. Securities;
     (ii) any downgrading in the rating of any debt securities of the Company by
     any "nationally recognized statistical rating organization" (as defined for
     purposes of Rule 436(g) under the Act), or any public announcement that any
     such organization has under surveillance or review

                                       13


<PAGE>

     its rating of any debt securities of the Company (other than an
     announcement with positive implications of a possible upgrading, and no
     implication of a possible downgrading, of such rating); (iii) any
     suspension or limitation of trading in securities generally on the New York
     Stock Exchange, or any setting of minimum prices for trading on such
     exchange, or any suspension of trading of any securities of the Company on
     any exchange or in the over-the-counter market; (iv) any banking moratorium
     declared by U.S. Federal or New York authorities; or (v) any outbreak or
     escalation of major hostilities in which the United States is involved, any
     declaration of war by Congress or any other substantial national or
     international calamity or emergency if, in the judgment of a majority in
     interest of the Underwriters including the Representatives, the effect of
     any such outbreak, escalation, declaration, calamity or emergency makes it
     impractical or inadvisable to proceed with completion of the public
     offering or the sale of and payment for the U.S. Securities.

          (e)  The Representatives shall have received an opinion, dated such
     Closing Date, of Sheppard, Mullin, Richter & Hampton LLP, counsel for the
     Company, to the effect that:

                 (i)  Each of the Company and its Subsidiaries has been duly
          incorporated and is an existing corporation in good standing under the
          laws of the State of its jurisdiction of incorporation, with corporate
          power and authority to own its properties and conduct its business as
          described in the Prospectuses; and, to the best of such counsel's
          knowledge, each of the Company and its Subsidiaries is duly qualified
          to do business as a foreign corporation in good standing in all other
          jurisdictions in which its ownership or lease of property or the 
          conduct of its business requires such qualification, except where 
          the failure to qualify would not have a Material Adverse Effect;

                 (ii)  The Company has authorized capitalization as set forth
          in the Prospectuses;

                 (iii)  The Offered Securities delivered on such Closing Date
          and all other outstanding shares of the Common Stock of the Company
          have been duly authorized and validly issued, are fully paid and
          nonassessable and conform to the description thereof contained in the
          Prospectuses; and the stockholders of the Company have no preemptive
          rights with respect to the Offered Securities;

                 (iv) Other than the Registration Rights Agreement, there are
          no contracts, agreements or understandings known to such counsel
          between the Company and any person granting such person the right to
          require the Company to file a registration statement under the Act
          with respect to any securities of the Company owned or to be owned by
          such person or to require the Company to include such securities in
          the securities registered pursuant to the Registration Statement or in
          any securities being registered pursuant to any other registration
          statement filed by the Company under the Act;

                 (v)  The Company is not and, after giving effect to the
          offering and sale of the Offered Securities and the application of the
          proceeds thereof as described in the Prospectus, will not be an
          "investment company" as defined in the Investment Company Act of 1940;

                 (vi)  No consent, approval, authorization or order of, or
          filing with, any governmental agency or body or any court is required
          for the consummation of the

                                       14


<PAGE>

          transactions contemplated by this Agreement or the Subscription
          Agreement in connection with the issuance or sale of the Offered
          Securities by the Company, except such as have been obtained and made
          under the Act and such as may be required under state securities laws;

                 (vii)  The execution, delivery and performance of this
          Agreement and the Subscription Agreement and the issuance and sale of
          the Offered Securities will not result in a breach or violation of any
          of the terms and provisions of, or constitute a default under, any
          Federal or California statute, rule or regulation, the Delaware
          General Corporation Law, or any rule, regulation or order of any
          governmental agency or body, or any court having jurisdiction over the
          Company or any Subsidiary of the Company or any of their properties,
          or any agreement or instrument to which the Company or any such
          Subsidiary is a party or by which the Company or any such Subsidiary
          is bound or to which any of the properties of the Company or any such
          Subsidiary is subject, or the charter or bylaws of the Company or any
          such Subsidiary, and the Company has full power and authority to
          authorize, issue and sell the Offered Securities as contemplated by
          this Agreement and the Subscription Agreement, respectively;

                 (viii)  The Initial Registration Statement was declared
          effective under the Act as of the date and time specified in such
          opinion, the Additional Registration Statement (if any) was filed and
          became effective under the Act as of the date and time (if
          determinable) specified in such opinion, each of the Prospectuses
          either were filed with the Commission pursuant to the subparagraph of
          Rule 424(b) specified in such opinion on the date specified therein or
          was included in the Initial Registration Statement or the Additional
          Registration Statement (as the case may be), and, to the best of such
          counsel's knowledge, no stop order suspending the effectiveness of a
          Registration Statement or any part thereof has been issued and no
          proceedings for that purpose have been instituted or are pending or
          contemplated under the Act, and each Registration Statement and each
          of the Prospectuses, and each amendment or supplement thereto, as of
          their respective effective or issue dates, complied as to form in all
          material respects with the requirements of the Act and the Rules and
          Regulations;

                 (ix)  After due inquiry, such counsel does not know of any
          legal or governmental proceedings required to be described in a
          Registration Statement or the Prospectuses which are not described as
          required or of any contracts or documents of a character required to
          be described in a Registration Statement or the Prospectuses or to be
          filed as exhibits to a Registration Statement which are not described
          and filed as required; and

                 (x)  This Agreement and the Subscription Agreement have been
          duly authorized, executed and delivered by the Company.

          Such counsel shall also state that on the basis of their involvement
     in the preparation of the Registration Statements and the amendments
     thereto, and the Prospectuses and any amendments or supplements thereto,
     and although they have not verified the accuracy or completeness of the
     statements contained therein or in any amendment thereto, nothing has come
     to the attention of such counsel which causes them to believe that the
     Registration Statement, as amended (other than the financial statements and
     notes thereto and supporting schedules and other financial and statistical
     information contained therein), contained any untrue statement of

                                       15


<PAGE>

     a material fact or omitted to state any material fact required to be stated
     therein or necessary to make the statements therein not misleading or that
     either of the Prospectuses, or any amendment or supplement thereto (other
     than the financial statements and notes thereto and supporting schedules
     and other financials and statistical information contained therein), as of
     its issue date or as of such Closing Date, contained any untrue statement
     of a material fact or omitted to state any material fact necessary in order
     to make the statements therein, in light of the circumstances under which
     they were made, not misleading; and such counsel does not know of any
     contracts or documents of a character required to be described in or to be
     filed as exhibits to any Registration Statement which are not described and
     filed as required.

          In rendering such opinion, such counsel may rely (A) as to matters
     involving the application of laws other than the laws of the United States
     and jurisdictions in which they are admitted, to the extent such counsel
     deems proper and to the extent specified in such opinion, if at all, upon
     an opinion or opinions (in form and substance reasonably satisfactory to
     Underwriters' counsel) of other counsel reasonably acceptable to
     Underwriters' counsel, familiar with the applicable laws, it being
     understood and agreed that with respect to matters involving the
     application of the law of the State of New York, the law firm of Kaye,
     Scholer, Fierman, Hays & Handler, LLP is counsel acceptable to
     Underwriters' counsel,  and (B) as to matters of fact, to the extent they
     deem proper, on certificates of responsible officers of the Company,
     PROVIDED, that copies of any such statements or certificates shall be
     delivered to Underwriters' counsel.  The opinions of such counsel for the
     Company shall state that the opinion of any such other counsel is in form
     satisfactory to such counsel and, in their opinion, you and they are
     justified in relying thereon.

          (f)  The Underwriters shall have received an opinion, dated such
     Closing Date, of Richard R. Molleur, Corporate Vice President and General
     Counsel of the Company, to the effect that:

                 (i)  The execution, delivery and performance of this Agreement
          and the Subscription Agreement will not result in a breach or
          violation of any of the terms and provisions of, or constitute a
          default under, any Federal or California statute, rule or regulation,
          the Delaware General Corporation Law, or any rule, regulation or order
          of any governmental agency or body, or any court having jurisdiction
          over the Company or any Subsidiary of the Company or any of their
          properties, or any material agreement or instrument to which the
          Company or any such Subsidiary is a party or by which the Company or
          any such Subsidiary is bound or to which any of the properties of the
          Company or any such Subsidiary is subject, or the charter or bylaws of
          the Company or any such Subsidiary; and the Company has full corporate
          power and authority to authorize, issue and sell the Offered
          Securities as contemplated by this Agreement and the Subscription
          Agreement, respectively; and

                 (ii)  To the knowledge of such counsel, there is no legal or
          governmental proceeding, pending or threatened, to which the Company
          or any of its Subsidiaries is subject which is required to be
          described in a Registration Statement or the Prospectuses and is not
          so described, and there is no contract or other document which is
          required to be described in a Registration Statement or the
          Prospectuses or is required to be filed as an exhibit to a
          Registration Statement which is not so described and filed as
          required.

                                       16


<PAGE>

          In rendering such opinion, such counsel shall opine as to the effect
     of the federal laws of the United States, the internal laws of the State of
     California and the General Corporation Law of the State of Delaware, and
     such counsel may assume that as to matters involving the application of
     laws of jurisdictions other than the laws of the State of California and
     the General Corporation Law of the State of Delaware, the laws of any such
     other jurisdiction are the same as the laws of the State of California.

          (g)  The Representatives shall have received from Latham & Watkins,
     counsel for the Underwriters, such opinion or opinions, dated such Closing
     Date, with respect to the incorporation of the Company, the validity of the
     Offered Securities delivered on such Closing Date, the Registration
     Statements, the Prospectuses and other related matters as the
     Representatives may require, and the Company shall have furnished to such
     counsel such documents as they request for the purpose of enabling them to
     pass upon such matters.

          (h)  The Representatives shall have received a certificate, dated such
     Closing Date, of the President or any Vice President and a principal
     financial or accounting officer of the Company in which such officers, to
     the best of their knowledge after reasonable investigation, shall state
     that: the representations and warranties of the Company in this Agreement
     are true and correct; the Company has complied with all agreements and
     satisfied all conditions on its part to be performed or satisfied hereunder
     at or prior to such Closing Date; no stop order suspending the
     effectiveness of any Registration Statement has been issued and no
     proceedings for that purpose have been instituted or are contemplated by
     the Commission; the Additional Registration Statement (if any) satisfying
     the requirements of subparagraphs (1) and (3) of Rule 462(b) was filed
     pursuant to Rule 462(b), including payment of the applicable filing fee in
     accordance with Rule 111(a) or (b) under the Act, prior to the time either
     Prospectus was printed and distributed to any Underwriter or Manager; and,
     subsequent to the respective dates of the most recent financial statements
     in the Prospectuses, there has been no material adverse change, nor any
     development or event involving a prospective material adverse change, in
     the condition (financial or other), business, properties or results of
     operations of the Company and its subsidiaries taken as a whole except as
     set forth in or contemplated by the Prospectuses or as described in such
     certificate.

          (i)  The Representatives shall have received a letter, dated such
     Closing Date, of Deloitte & Touche LLP which meets the requirements of
     subsection (a) of this Section, except that the specified date referred to
     in such subsection will be a date not more than three days prior to such
     Closing Date for the purposes of this subsection.

          (j)  The Representatives shall have received a letter, dated such
     Closing Date, of Price Waterhouse LLP which meets the requirements of
     subsection (b) of this Section, except that the specified date referred to
     in such subsection will be a date not more than three days prior to such
     Closing Date for the purposes of this subsection.

          (k)  On such Closing Date, the Managers shall have purchased the
     International Firm Securities or the International Optional Securities, as
     the case may be, pursuant to the Subscription Agreement.

     The Company will furnish the Representatives with such conformed copies of
such opinions, certificates, letters and documents as the Representatives
reasonably request. CSFBC may in its sole discretion waive on behalf of the
Underwriters compliance with any conditions to the obligations of the
Underwriters hereunder, whether in respect of an Optional Closing Date or
otherwise.

     7.  INDEMNIFICATION AND CONTRIBUTION.  (a)  The Company will indemnify and
hold harmless each Underwriter against any losses, claims, damages or
liabilities, joint or several, to which such Underwriter may become subject,
under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon any
untrue statement or alleged untrue statement of any material fact contained in
any Registration Statement, either of the Prospectuses, or any amendment or
supplement thereto, or any related preliminary prospectus, or arise out of or
are based upon the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, and will reimburse each Underwriter for any legal or other expenses
reasonably incurred by such Underwriter in connection with investigating or
defending any such loss, claim, damage, liability or action as such expenses are
incurred; provided, however, that the Company will not be liable in any such
case to the extent that any such loss, claim, damage or liability arises out of
or is based upon an untrue statement or alleged untrue statement in or omission
or alleged omission from any of such documents in reliance upon and in
conformity with written information furnished to the Company by any Underwriter
through the Representatives specifically for use therein, it being understood
and agreed that the only information furnished by any Underwriter consists of
the information described as such in subsection (b) below.

     (b)  Each Underwriter will severally and not jointly indemnify and hold
harmless the Company against any losses, claims, damages or liabilities to which
the Company may become subject, under the Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon any untrue statement or alleged untrue statement of any
material fact contained in any Registration Statement, either of the
Prospectuses, or any amendment or supplement thereto, or any related preliminary
prospectus, or arise out of or are based upon the omission or the alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, in each case to the
extent, but only to the extent, that such untrue statement or alleged untrue
statement or omission or alleged omission was made in reliance upon and in
conformity with written information furnished to the Company by such Underwriter
through the Representatives specifically for use therein, and will reimburse any
legal or other expenses reasonably incurred by the Company in connection with
investigating or defending any such loss, claim, damage, liability or action as
such expenses are incurred, it being understood and agreed that the only such
information furnished by any Underwriter consists of the following information
in the U.S. Prospectus furnished on behalf of each Underwriter: the last
paragraph at the bottom of the cover page concerning the terms of the offering
by the Underwriters, the legend concerning over-allotments and stabilizing on
the inside front cover page and the concession and reallowance figures appearing
in the fifth paragraph under the caption "Underwriting."

     (c)  Promptly after receipt by an indemnified party under this Section of
notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under
subsection (a) or (b) above, notify the indemnifying party of the commencement
thereof; but the omission so to notify the indemnifying party will not relieve
it from any liability which it may have to any indemnified party otherwise than
under subsection (a) or (b) above.  In case any such action is brought against
any indemnified party and it notifies the indemnifying party of the commencement
thereof, the indemnifying party will be entitled to participate therein and, to
the extent that it may wish, jointly with any other indemnifying party similarly
notified, to assume the defense thereof, with counsel satisfactory to such
indemnified party (who shall not, except with the consent of the indemnified
party, be counsel to the indemnifying party), and after notice from the
indemnifying party to such indemnified party of its election so to assume the
defense thereof, the indemnifying party will not be liable to such indemnified
party under this Section for any legal or other expenses subsequently incurred
by such indemnified party in connection with the defense thereof other than
reasonable costs of investigation.  No indemnifying party shall, without the
prior written consent

                                       18


<PAGE>

of the indemnified party, effect any settlement of any pending or threatened
action in respect of which any indemnified party is or could have been a party
and indemnity could have been sought hereunder by such indemnified party unless
such settlement includes an unconditional release of such indemnified party from
all liability on any claims that are the subject matter of such action.

     (d)  If the indemnification provided for in this Section is unavailable or
insufficient to hold harmless an indemnified party under subsection (a) or (b)
above, then each indemnifying party shall contribute to the amount paid or
payable by such indemnified party as a result of the losses, claims, damages or
liabilities referred to in subsection (a) or (b) above (i) in such proportion as
is appropriate to reflect the relative benefits received by the Company on the
one hand and the Underwriters on the other from the offering of the U.S.
Securities or (ii) if the allocation provided by clause (i) above is not
permitted by applicable law, in such proportion as is appropriate to reflect not
only the relative benefits referred to in clause (i) above but also the relative
fault of the Company on the one hand and the Underwriters on the other in
connection with the statements or omissions which resulted in such losses,
claims, damages or liabilities as well as any other relevant equitable
considerations.  The relative benefits received by the Company on the one hand
and the Underwriters on the other shall be deemed to be in the same proportion
as the total net proceeds from the offering of the U.S. Securities (before
deducting expenses) received by the Company bear to the total underwriting
discounts and commissions received by the Underwriters.  The relative fault
shall be determined by reference to, among other things, whether the untrue or
alleged untrue statement of a material fact or the omission or alleged omission
to state a material fact relates to information supplied by the Company or the
Underwriters and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such untrue statement or omission.  The
amount paid by an indemnified party as a result of the losses, claims, damages
or liabilities referred to in the first sentence of this subsection (d) shall be
deemed to include any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating or defending any action or
claim which is the subject of this subsection (d).  Notwithstanding the
provisions of this subsection (d), no Underwriter shall be required to
contribute any amount in excess of the amount by which the total price at which
the U.S. Securities underwritten by it and distributed to the public were
offered to the public exceeds the amount of any damages which such Underwriter
has otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission.  No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation.  The Underwriters' obligations in this subsection (d) to
contribute are several in proportion to their respective underwriting
obligations and not joint.

     (e)  The obligations of the Company under this Section shall be in addition
to any liability which the Company may otherwise have and shall extend, upon the
same terms and conditions, to each person, if any, who controls any Underwriter
within the meaning of the Act or the Exchange Act; and the obligations of the
Underwriters under this Section shall be in addition to any liability which the
respective Underwriters may otherwise have and shall extend, upon the same terms
and conditions, to each director of the Company, to each officer of the Company
who has signed a Registration Statement and to each person, if any, who controls
the Company within the meaning of the Act or the Exchange Act.

     8.  DEFAULT OF UNDERWRITERS.  If any Underwriter or Underwriters default in
their obligations to purchase U.S. Securities hereunder on either the First or
any Optional Closing Date and the aggregate number of shares of U.S. Securities
that such defaulting Underwriter or Underwriters agreed but failed to purchase
does not exceed 10% of the total number of shares of U.S. Securities that the
Underwriters are obligated to purchase on such Closing Date, CSFBC may make
arrangements satisfactory to the Company for the purchase of such U.S.
Securities by other persons, including any of the Underwriters,

                                       19


<PAGE>

but if no such arrangements are made by such Closing Date the non-defaulting
Underwriters shall be obligated severally, in proportion to their respective
commitments hereunder, to purchase the U.S. Securities that such defaulting
Underwriters agreed but failed to purchase on such Closing Date.  If any
Underwriter or Underwriters so default and the aggregate number of shares of
U.S. Securities with respect to which such default or defaults occur exceeds 10%
of the total number of shares of U.S. Securities that the Underwriters are
obligated to purchase on such Closing Date and arrangements satisfactory to
CSFBC and the Company for the purchase of such U.S. Securities by other persons
are not made within 36 hours after such default, this Agreement will terminate
without liability on the part of any non-defaulting Underwriter or the Company,
except as provided in Section 9 (provided that if such default occurs with
respect to U.S. Optional Securities after the First Closing Date, this Agreement
will not terminate as to the U.S. Firm Securities or any U.S. Optional
Securities purchased prior to such termination).  As used in this Agreement, the
term "Underwriter" includes any person substituted for an Underwriter under this
Section.  Nothing herein will relieve a defaulting Underwriter from liability
for its default.

     9.  SURVIVAL OF CERTAIN REPRESENTATIONS AND OBLIGATIONS.  The respective
indemnities, agreements, representations, warranties and other statements of the
Company or its officers and of the several Underwriters set forth in or made
pursuant to this Agreement will remain in full force and effect, regardless of
any investigation, or statement as to the results thereof, made by or on behalf
of any Underwriter, the Company or any of their respective representatives,
officers or directors or any controlling person, and will survive delivery of
and payment for the U.S. Securities.  If this Agreement is terminated pursuant
to Section 8 or if for any reason the purchase of the U.S. Securities by the
Underwriters is not consummated, the Company shall remain responsible for the
expenses to be paid or reimbursed by it pursuant to Section 5 and the respective
obligations of the Company and the Underwriters pursuant to Section 7 shall
remain in effect and if any U.S. Securities have been purchased hereunder the
representations and warranties in Section 2 and all obligations under Section 5
shall also remain in effect.  If the purchase of the U.S. Securities by the
Underwriters is not consummated for any reason other than solely because of the
termination of this Agreement pursuant to Section 8 or the occurrence of any
event specified in clause (iii), (iv), or (v) of Section 6(d), the Company will
reimburse the Underwriters for all out-of-pocket expenses (including fees and
disbursements of counsel) reasonably incurred by them in connection with the
offering of the U.S. Securities.

     10.  NOTICES.  All communications hereunder will be in writing and, if sent
to the Underwriters, will be mailed, delivered or telegraphed and confirmed to
the Representatives, c/o CS First Boston Corporation, Park Avenue Plaza, New

Vice President and Chief Financial Officer;  provided, however, that any notice
to an Underwriter pursuant to Section 7 will be mailed, delivered or telegraphed
and confirmed to such Underwriter.

     11.  SUCCESSORS.  This Agreement will inure to the benefit of and be
binding upon the parties hereto and their respective successors and the officers
and directors and controlling persons referred to in Section 7, and no other
person will have any right or obligation hereunder.

     12.  REPRESENTATION OF UNDERWRITERS.  The Representatives will act for the
several Underwriters in connection with this financing, and any action under
this Agreement taken by the Representatives jointly or by CSFBC will be binding
upon all the Underwriters.

     13.  COUNTERPARTS.  This Agreement may be executed in any number of

counterparts shall together constitute one and the same Agreement.

ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES
OF CONFLICTS OF LAWS.

TO:  CS FIRST BOSTON LIMITED
     MERRILL LYNCH INTERNATIONAL
     SALOMON BROTHERS INTERNATIONAL LIMITED
     [Other Managers],


C/O: CS FIRST BOSTON LIMITED ("CSFBL")
     One Cabot Square
     London, England E14 4QJ

Dear Sirs:

     1.  INTRODUCTORY.  Northrop Grumman Corporation, a Delaware corporation
(the "Company"), proposes to issue and sell (the "International Offering") to
the several Managers named in Schedule A hereto (the "Managers") _______ shares
(the "International Firm Securities") of its common stock, $1.00 par value (the
"Securities").

     It is understood that the Company is concurrently entering into an
Underwriting Agreement, dated the date hereof (the "Underwriting Agreement"),
with certain United States underwriters listed in Schedule A thereto (the "U.S.
Underwriters"), for whom CS First Boston Corporation ("CSFBC"), Merrill Lynch,
Pierce, Fenner & Smith Incorporated and Salomon Brothers Inc are acting as
representatives (the "U.S. Representatives"), relating to the concurrent
offering and sale of ______ shares of Securities (the " U.S. Firm Securities")
in the United States and Canada (the "U.S. Offering").

     In addition, the Company proposes
 to issue and sell (i) to the U.S.
Underwriters, at the option of the U.S. Underwriters, an aggregate of not more
than _____ additional shares of Securities (the "U.S. Optional Securities") and
(ii) to the Managers, at the option of the Managers, an aggregate of not more
than _____ additional shares of Securities (the "International Optional
Securities").  The U.S. Firm Securities and the U.S. Optional Securities are
hereinafter called the "U.S. Securities"; the International Firm Securities and
the International Optional Securities are hereinafter called the "International
Securities"; the U.S. Firm Securities and the International Firm Securities are
hereinafter called the "Firm Securities"; the U.S. Optional Securities and the
International Optional Securities are hereinafter called the "Optional
Securities."  The U.S. Securities and the International Securities are
collectively referred to as the "Offered Securities."  To provide for the
coordination of their activities, the U.S. Underwriters and the Managers have
entered into an Agreement Between U.S. Underwriters and Managers which permits
them, among other things, to sell the Offered Securities to each other for
purposes of resale.


<PAGE>

     The Company hereby agrees with the several Managers as follows:

     2.  REPRESENTATIONS AND WARRANTIES OF THE COMPANY.  The Company represents
and warrants to, and agrees with, the several Managers that:

          (a)  A registration statement (No. 333-________) relating to the
     Offered Securities, including a form of prospectus relating to the U.S.
     Securities and a form of prospectus relating to the International
     Securities being offered in the International Offering, has been filed with
     the Securities and Exchange Commission (the "Commission") and either (i)
     has been declared effective under the Securities Act of 1933 (the "Act")
     and is not proposed to be amended or (ii) is proposed to be amended by
     amendment or post-effective amendment.  If such registration statement (the
     "initial registration statement") has been declared effective, either
     (A) an additional registration statement (the "additional registration
     statement") relating to the Offered Securities may have been filed with the
     Commission pursuant to Rule 462(b) ("Rule 462(b)") under the Act and, if so
     filed, has become effective upon filing pursuant to such Rule and the
     Offered Securities all have been duly registered under the Act pursuant to
     the initial registration statement and, if applicable, the additional
     registration statement or (B) such an additional registration statement is
     proposed to be filed with the Commission pursuant to Rule 462(b) and will
     become effective upon filing pursuant to such Rule and upon such filing the
     Offered Securities will all have been duly registered under the Act
     pursuant to the initial registration statement and such additional
     registration statement.  If the Company does not propose to amend the
     initial registration statement or, if an additional registration statement
     has been filed and the Company does not propose to amend it, and if any
     post-effective amendment to either such registration statement has been
     filed with the Commission prior to the execution and delivery of this
     Agreement, the most recent amendment (if any) to each such registration
     statement has been declared effective by the Commission or has become
     effective upon filing pursuant to Rule 462(c) ("Rule 462(c)") under the Act
     or, in the case of the additional registration statement, Rule 462(b).  For
     purposes of this Agreement, "Effective Time" with respect to the initial
     registration statement or, if filed prior to the execution and delivery of
     this Agreement, the additional registration statement means (i) if the
     Company has advised CSFBL that it does not propose to amend such
     registration statement, the date and time as of which such registration
     statement, or the most recent post-effective amendment thereto (if any)
     filed prior to the execution and delivery of this Agreement, was declared
     effective by the Commission or has become effective upon filing pursuant to
     Rule 462(c), or (ii) if the Company has advised CSFBL that it proposes to
     file an amendment or post-effective amendment to such registration
     statement, the date and time as of which such registration statement, as
     amended by such amendment or post-effective amendment, as the case may be,
     is declared effective by the Commission.  If an additional registration
     statement has not been filed prior to the execution and delivery of this
     Agreement but the Company has advised CSFBL that it proposes to file one,
     "Effective Time" with respect to such additional registration statement
     means the date and time as of which such registration statement is filed
     and becomes effective pursuant to Rule 462(b).  "Effective Date" with
     respect to the initial registration statement or the additional
     registration statement (if any) means the date of the Effective Time
     thereof.  The initial registration statement, as amended at its Effective
     Time, including all material incorporated by reference therein, including
     all information contained in the additional registration statement (if any)
     and deemed to be a part of the initial registration statement as of the
     Effective Time of the additional registration statement pursuant to the
     General Instructions of the Form on which it is filed and including all
     information (if any)

                                        2


<PAGE>

     deemed to be a part of the initial registration statement as of its
     Effective Time pursuant to Rule 430A(b) ("Rule 430A(b)") under the Act, is
     hereinafter referred to as the "Initial Registration Statement."  The
     additional registration statement, as amended at its Effective Time,
     including the contents of the Initial Registration Statement incorporated
     by reference therein and including all information (if any) deemed to be a
     part of the additional registration statement as of its Effective Time
     pursuant to Rule 430A(b), is hereinafter referred to as the "Additional
     Registration Statement." The Initial Registration Statement and the
     Additional Registration Statement are hereinafter referred to collectively
     as the "Registration Statements" and individually as a "Registration
     Statement."  The form of prospectus relating to the U.S. Securities and the
     form of prospectus relating to the International Securities, each as first
     filed with the Commission pursuant to and in accordance with Rule 424(b)
     ("Rule 424(b)") under the Act or (if no such filing is required) as
     included in the Registration Statement, including all material incorporated
     by reference in each such prospectus, are hereinafter referred to as the
     "U.S. Prospectus" and the "International Prospectus," respectively, and
     collectively as the "Prospectuses," including all material incorporated by
     reference in such prospectus, is hereinafter referred to as the "U.S.
     Prospectus," and the form of prospectus relating to the International
     Securities, which is identical to the U.S. Prospectus except for the
     outside front cover page, the inside front cover page, the outside back
     cover page and the text under the captions "Underwriting" and "Subscription
     and Sale" in the U.S. Prospectus and the form of prospectus relating to the
     International Securities, respectively (copies of such pages and text
     having been heretofore delivered to CSFBL on behalf of the Managers), is
     hereinafter referred to as the "International Prospectus"; and the U.S.
     Prospectus and the International Prospectus are hereinafter collectively
     referred to as the "Prospectuses."  No document has been or will be
     prepared or distributed in reliance on Rule 434 under the Act.

          (b)  If the Effective Time of the Initial Registration Statement is
     prior to the execution and delivery of this Agreement:  (i) on the
     Effective Date of the Initial Registration Statement, the Initial
     Registration Statement conformed in all respects to the requirements of the
     Act and the rules and regulations of the Commission (the "Rules and
     Regulations") and did not include any untrue statement of a material fact
     or omit to state any material fact required to be stated therein or
     necessary to make the statements therein not misleading, (ii) on the
     Effective Date of the Additional Registration Statement (if any), each
     Registration Statement conformed, or will conform, in all respects to the
     requirements of the Act and the Rules and Regulations and did not include,
     or will not include, any untrue statement of a material fact and did not
     omit, or will not omit, to state any material fact required to be stated
     therein or necessary to make the statements therein not misleading, and
     (iii) on the date of this Agreement, the Initial Registration Statement
     and, if the Effective Time of the Additional Registration Statement is
     prior to the execution and delivery of this Agreement, the Additional
     Registration Statement each conforms, and at the time of filing of each of
     the Prospectuses pursuant to Rule 424(b) or (if no such filing is required)
     at the Effective Date of the Additional Registration Statement in which the
     Prospectuses are included, each Registration Statement and each of the
     Prospectuses will conform, in all respects to the requirements of the Act
     and the Rules and Regulations, and none of such documents includes, or will
     include, any untrue statement of a material fact or omits, or will omit, to
     state any material fact required to be stated therein or necessary to make
     the statements therein not misleading.  If the Effective Time of the
     Initial Registration Statement is subsequent to the execution and delivery
     of this Agreement: on the Effective Date of the Initial Registration
     Statement, the Initial Registration Statement and each of the Prospectuses

                                        3


<PAGE>

     will conform in all respects to the requirements of the Act and the Rules
     and Regulations, none of such documents will include any untrue statement
     of a material fact or will omit to state any material fact required to be
     stated therein or necessary to make the statements therein not misleading,
     and no Additional Registration Statement has been or will be filed.  The
     two preceding sentences do not apply to statements in or omissions from a
     Registration Statement or either of the Prospectuses based upon written
     information furnished to the Company by any Manager through CSFBL or by any
     U.S. Underwriter through the U.S. Representatives  specifically for use
     therein, it being understood and agreed that the only such information is
     that described as such in Section 7(b).

          (c)  The Company has been duly incorporated and is an existing
     corporation in good standing under the laws of the State of Delaware, with
     power and authority (corporate and other) to own its properties and conduct
     its business as described in the Prospectuses; and the Company is duly
     qualified to do business as a foreign corporation in good standing in all
     other jurisdictions in which its ownership or lease of property or the
     conduct of its business requires such qualification, except where the
     failure to be so qualified would not, individually or in the aggregate,
     have a material adverse effect on the properties, business, results of
     operations, condition (financial or otherwise), affairs or prospects of the
     Company and its significant subsidiaries listed on Schedule B hereto, (each
     a "Subsidiary" and, collectively, the "Subsidiaries"), taken as a whole (a
     "Material Adverse Effect").

          (d)  Each Subsidiary of the Company has been duly incorporated and is
     an existing corporation in good standing under the laws of the jurisdiction
     of its incorporation, with power and authority (corporate and other) to own
     its properties and conduct its business as described in the Prospectuses;
     and each Subsidiary of the Company is duly qualified to do business as a
     foreign corporation in good standing in all other jurisdictions in which
     its ownership or lease of property or the conduct of its business requires
     such qualification, except where such failure would not, individually or in
     the aggregate, have a Material Adverse Effect; all of the issued and
     outstanding capital stock of each Subsidiary of the Company has been duly
     authorized and validly issued and is fully paid and nonassessable; and the
     capital stock of each Subsidiary owned by the Company, directly or through
     Subsidiaries, is owned free from liens, encumbrances and defects.

          (e)  The Offered Securities and all other outstanding shares of
     capital stock of the Company have been duly authorized; all outstanding
     shares of capital stock of the Company are, and, when the Offered
     Securities have been delivered and paid for in accordance with this
     Agreement and the Underwriting Agreement on each Closing Date (as defined
     below), such Offered Securities will have been, validly issued, fully paid
     and nonassessable and will conform to the description thereof contained in
     the Prospectuses; and the stockholders of the Company have no preemptive
     rights with respect to the Securities.

          (f)  Except as disclosed in the Prospectuses, there are no contracts,
     agreements or understandings between the Company and any person that would
     give rise to a valid claim against the Company or any Manager or U.S.
     Underwriter for a brokerage commission, finder's fee or other like payment.

          (g)  Other than the Registration Rights Agreement, dated as of March

     Securities Inc. related to the Company's 7% Notes Due 2006, 7 1/2%
     Debentures Due 2016 and 7 3/4% Debentures Due 2026, there are no contracts,
     agreements or understandings between the Company and any person granting
     such person the right to require the Company to file a registration
     statement under the Act with respect to any securities of the Company owned
     or to be owned by such person or to require the Company to include such
     securities in the securities registered pursuant to a Registration
     Statement or in any securities being registered pursuant to any other
     registration statement filed by the Company under the Act.

          (h)  The Offered Securities have been approved for listing on The New
     York Stock Exchange and the Pacific Stock Exchange subject to notice of
     issuance.

          (i)  No consent, approval, authorization, or order of, or filing with,
     any governmental agency or body, including, without limitation, the United
     States Department of Defense, or any court is required for the consummation
     of the transactions contemplated by this Agreement or the Underwriting
     Agreement in connection with the issuance and sale of the Offered
     Securities by the Company, except such as have been obtained and made under
     the Act and such as may be required under state securities laws.

          (j)  The execution, delivery and performance of this Agreement and the
     Underwriting Agreement, and the issuance and sale of the Offered Securities
     will not result in a breach or violation of any of the terms and provisions
     of, or constitute a default under, (i) any statute, any rule, regulation or
     order of any governmental agency or body or any court, domestic or foreign,
     having jurisdiction over the Company or any Subsidiary of the Company or
     any of their properties, or any agreement or instrument to which the
     Company or any such Subsidiary is a party or by which the Company or any
     such Subsidiary is bound or to which any of the properties of the Company
     or any such Subsidiary is subject, except for any such breach, violation or
     default which would not have a Material Adverse Effect, or (ii) the charter
     or bylaws of the Company or any such Subsidiary, and the Company has full
     power and authority to authorize, issue and sell the Offered Securities as
     contemplated by this Agreement and the Underwriting Agreement,
     respectively.

          (k)  This Agreement and the Underwriting Agreement have been duly
     authorized, executed and delivered by the Company.

          (l)  Except as disclosed in the Prospectuses, the Company and its
     Subsidiaries have good and marketable title to all real properties and all
     other properties and assets owned by them, in each case free from liens,
     encumbrances and defects that would materially affect the value thereof or
     materially interfere with the use made or to be made thereof by them; and
     except as disclosed in the Prospectuses, the Company and its Subsidiaries
     hold any leased real or personal property under valid and enforceable
     leases with no exceptions that would materially interfere with the use made
     or to be made thereof by them.

          (m)  The Company and its Subsidiaries possess adequate certificates,
     authorities or permits issued by appropriate governmental agencies or
     bodies necessary to conduct the business now operated by them and have not
     received any notice of proceedings relating to the revocation

                                        5


<PAGE>

     or modification of any such certificate, authority or permit that, if
     determined adversely to the Company or any of its Subsidiaries, would
     individually or in the aggregate have a Material Adverse Effect.

          (n)  No labor dispute with the employees of the Company or any
     Subsidiary exists or, to the knowledge of the Company, is imminent that
     might have a Material Adverse Effect.

          (o)  The Company and its Subsidiaries own, possess or can acquire on
     reasonable terms, adequate trademarks, trade names and other rights to
     inventions, know-how, patents, copyrights, confidential information and
     other intellectual property (collectively, "intellectual property rights")
     necessary to conduct the business now operated by them, or presently
     employed by them, and have not received any notice of infringement of or
     conflict with asserted rights of others with respect to any intellectual
     property rights that, if determined adversely to the Company or any of its
     Subsidiaries, would individually or in the aggregate have a Material
     Adverse Effect.

          (p)  Except as disclosed in the Prospectuses, neither the Company nor
     any of its Subsidiaries is in violation of any statute, any rule,
     regulation, decision or order of any governmental agency or body or any
     court, domestic or foreign, relating to the use, disposal or release of
     hazardous or toxic substances or relating to the protection or restoration
     of the environment or human exposure to hazardous or toxic substances
     (collectively, "environmental laws"), owns or operates any real property
     contaminated with any substance that is subject to any environmental laws,
     is liable for any off-site disposal or contamination pursuant to any
     environmental laws, or is subject to any claim relating to any
     environmental laws, which violation, contamination, liability or claim
     would individually or in the aggregate have a Material Adverse Effect; and
     the Company is not aware of any pending investigation which might lead to
     such a claim.

          (q)  Except as disclosed in the Prospectuses, there are no pending
     actions, suits or proceedings against or affecting the Company, any of its
     Subsidiaries or any of their respective properties that, if determined
     adversely to the Company or any of its Subsidiaries, would individually or
     in the aggregate have a Material Adverse Effect, or would materially and
     adversely affect the ability of the Company to perform its obligations
     under this Agreement or the Underwriting Agreement, or which are otherwise
     material in the context of the sale of the Offered Securities; and no such
     actions, suits or proceedings are threatened or, to the Company's
     knowledge, contemplated.

          (r)  The financial statements included in each Registration Statement
     and the Prospectuses present fairly the financial position of the Company
     and its consolidated subsidiaries as of the dates shown and their results
     of operations and cash flows for the periods shown, and such financial
     statements have been prepared in conformity with the generally accepted
     accounting principles in the United States applied on a consistent basis;
     the schedules included in each Registration Statement present fairly the
     information required to be stated therein; and the assumptions used in
     preparing the pro forma financial statements included in each Registration
     Statement and the Prospectus provide a reasonable basis for presenting the
     significant effects directly attributable to the transactions or events
     described therein, the related pro forma adjustments give appropriate
     effect to those assumptions, and the pro forma columns

                                        6


<PAGE>

     therein reflect the proper application of those adjustments to the
     corresponding historical financial statement amounts.

          (s)  Except as disclosed in the Prospectuses, since the date of the
     latest audited financial statements included in the Prospectuses there has
     been no material adverse change, nor any development or event involving a
     prospective material adverse change, in the condition (financial or other),
     business, properties or results of operations of the Company and its
     Subsidiaries taken as a whole, and, except as disclosed in or contemplated
     by the Prospectuses, there has been no dividend or distribution of any kind
     declared, paid or made by the Company on any class of its capital stock.

          (t)  The Company is not and, after giving effect to the offering and
     sale of the Offered Securities and the application of the proceeds thereof
     as described in the Prospectuses, will not be an "investment company" as
     defined in the Investment Company Act of 1940.

          (u)  Neither the Company nor any of its affiliates does business with
     the government of Cuba or with any person or affiliate located in Cuba
     within the meaning of Section 517.075, Florida Statutes and the Company
     agrees to comply with such Section if prior to the completion of the
     distribution of the Offered Securities it commences doing such business.

     3.  PURCHASE, SALE AND DELIVERY OF OFFERED SECURITIES.  On the basis of the
representations, warranties and agreements herein contained, but subject to the
terms and conditions herein set forth, the Company agrees to sell to the
Managers, and the Managers agree, severally and not jointly, to purchase from
the Company, at a purchase price of U.S. $_____ per share, the respective
numbers of shares of International Firm Securities set forth opposite the names
of the Managers in Schedule A hereto.

     The Company will deliver the International Firm Securities to CSFBL for the
accounts of the Managers, at the office of CSFBC, against payment of the
purchase price in U.S. dollars in funds available on the same day by wire
transfer to the account of the Company at a bank acceptable to CSFBL or by
official Federal Reserve Bank check or checks drawn to the order of the Company
at the office of Latham & Watkins, 633 W. Fifth Street, Suite 4000, Los Angeles,
CA  90071-2007, at 10:00 A.M., New York time, on May ___, 1996, or at such other
time not later than seven full business days thereafter as CSFBL and the Company
determine, such time being herein referred to as the "First Closing Date." For
purposes of Rule 15c6-1 under the Securities Exchange Act of 1934, the First
Closing Date (if later than the otherwise applicable settlement date) shall be
the settlement date for payment of funds and delivery of securities for all the
Offered Securities sold pursuant to the U.S. Offering and the International
Offering.  The certificates for the International Firm Securities so to be
delivered will be in definitive form, in such denominations and registered in
such names as CSFBL requests and will be made available for checking and
packaging at the office of CSFBC, at least 24 hours prior to the First Closing
Date.

     In addition, upon written notice from CSFBC given to the Company from time
to time not more than 30 days subsequent to the date of the Prospectuses, the
Managers may purchase all or less than all of the International Optional
Securities at the purchase price per Security to be paid for the International
Firm Securities.  The International Optional Securities to be purchased by the
Managers on any Optional Closing Date shall be in the same proportion to all the
Optional Securities to be purchased by the Managers and U.S. Underwriters on
such Optional Closing Date as the International Firm Securities bear

                                        7


<PAGE>

to all the Firm Securities.  The Company agrees to sell to the Managers such
International Optional Securities and the Managers agree, severally and not
jointly, to purchase such International Optional Securities.  Such International
Optional Securities shall be purchased for the account of each Manager in the
same proportion as the number of shares of International Firm Securities set
forth opposite such Manager's name bears to the total number of shares of
International Firm Securities (subject to adjustment by CSFBC to eliminate
fractions) and may be purchased by the Managers only for the purpose of covering
over-allotments made in connection with the sale of the International Firm
Securities.  No Optional Securities shall be sold or delivered unless the
International Firm Securities and the U.S. Firm Securities previously have been,
or simultaneously are, sold and delivered.  The right to purchase the Optional
Securities or any portion thereof may be exercised from time to time and to the
extent not previously exercised may be surrendered and terminated at any time
upon notice by CSFBC on behalf of the Managers and the U.S. Underwriters to the
Company.  It is understood that CSFBC is authorized to make payment for and
accept delivery of such Optional Securities on behalf of the U.S. Underwriters
and Managers pursuant to the terms of CSFBC's instructions to the Company.

     Each time for the delivery of and payment for the International Optional
Securities, being herein referred to as an "Optional Closing Date," which may be
the First Closing Date (the First Closing Date and each Optional Closing Date,
if any, being sometimes referred to as a "Closing Date"), shall be determined by
CSFBC but shall be not later than five full business days after written notice
of election to purchase Optional Securities is given.  The Company will deliver
the International Optional Securities being purchased on each Optional Closing
Date to CSFBL for the accounts of the several Managers, at the office of CSFBC,
against payment of the purchase price in U.S. dollars in funds available on the
same day by wire transfer to the account of the Company at a bank acceptable to
CSFBL or by official Federal Reserve Bank check or checks drawn to the order of
the Company, at the office of Latham & Watkins, 633 W. Fifth Street, Los
Angeles, CA  90071-2007.  The certificates for the International Optional
Securities will be in definitive form, in such denominations and registered in
such names as CSFBL requests upon reasonable notice prior to such Optional
Closing Date and will be made available for checking and packaging at the office
of CSFBC, at a reasonable time in advance of such Optional Closing Date.

     The Company will pay to the Managers as aggregate compensation for their
commitments hereunder and for their services in connection with the purchase of
the International Securities and the management of the offering thereof, if the
sale and delivery of the International Securities to the Managers provided
herein is consummated, an amount equal to U.S. $ _____ per International
Security purchased, which may be divided among the Managers in such proportions
as they may determine.  Such payment will be made on the First Closing Date in
the case of the International Firm Securities and on each Optional Closing Date
in the case of the International Optional Securities sold to the Manager on such
Closing Date, in each case by way of deduction by the Managers of said amount
from the purchase price for the International Securities referred to above.

     4.  OFFERING BY MANAGERS.  It is understood that the several Managers
propose to offer the International Securities for sale to the public as set
forth in the International Prospectus.

     In connection with the distribution of the International Securities, the
Managers, through a stabilizing manager, may over-allot or effect transactions
on any exchange, in any over-the-counter market or otherwise which stabilize or
maintain the market prices of the International Securities at levels other than
those which might otherwise prevail, but in such event and in relation thereto,
the Managers


                                        8


<PAGE>

will act for themselves and not as agents of the Company, and any loss resulting
from over-allotment and stabilization will be borne, and any profit arising
therefrom will be beneficially retained, by the Managers.  Such stabilizing, if
commenced, may be discontinued at any time.

     5.   CERTAIN AGREEMENTS OF THE COMPANY.  The Company agrees with the
          several Managers that:

          (a)  If the Effective Time of the Initial Registration Statement is
     prior to the execution and delivery of this Agreement, the Company will
     file each of the Prospectuses with the Commission pursuant to and in
     accordance with subparagraph (1) (or, if applicable and if consented to by
     CSFBL, subparagraph (4)) of Rule 424(b) not later than the earlier of (A)
     the second business day following the execution and delivery of this
     Agreement or (B) the fifteenth business day after the Effective Date of the
     Initial Registration Statement.

     The Company will advise CSFBL promptly of any such filing pursuant to
     Rule 424(b).  If the Effective Time of the Initial Registration Statement
     is prior to the execution and delivery of this Agreement and an additional
     registration statement is necessary to register a portion of the Offered
     Securities under the Act but the Effective Time thereof has not occurred as
     of such execution and delivery, the Company will file the additional
     registration statement or, if filed, will file a post-effective amendment
     thereto with the Commission pursuant to and in accordance with Rule 462(b)
     on or prior to 10:00 P.M., New York time, on the date of this Agreement or,
     if earlier, on or prior to the time either Prospectus is printed and
     distributed to any Manager or U.S. Underwriter, or will make such filing at
     such later date as shall have been consented to by CSFBL.

          (b)  The Company will advise CSFBL promptly of any proposal to amend
     or supplement the initial or any additional registration statement as filed
     or either of the related prospectuses or the Initial Registration
     Statement, the Additional Registration Statement (if any) or either of the
     Prospectuses and will not effect such amendment or supplementation without
     CSFBL's prior consent; and the Company will also advise CSFBL promptly of
     the effectiveness of each Registration Statement (if its Effective Time is
     subsequent to the execution and delivery of this Agreement) and of any
     amendment or supplementation of a Registration Statement or either of the
     Prospectuses and of the institution by the Commission of any stop order
     proceedings in respect of a Registration Statement and will use its best
     efforts to prevent the issuance of any such stop order and to obtain as
     soon as possible its lifting, if issued.

          (c)  If, at any time when a prospectus relating to the Offered
     Securities is required to be delivered under the Act in connection with
     sales by any U.S. Underwriter, Manager or dealer, any event occurs as a
     result of which either or both of the Prospectuses as then amended or
     supplemented would include an untrue statement of a material fact or omit
     to state any material fact necessary to make the statements therein, in the
     light of the circumstances under which they were made, not misleading, or
     if it is necessary at any time to amend either or both of the Prospectuses
     to comply with the Act, the Company will promptly notify CSFBL of such
     event and will promptly prepare and file with the Commission, at its own
     expense, an amendment or supplement which will correct such statement or
     omission or an amendment which will effect such compliance.  Neither
     CSFBL's consent to, nor the Managers' delivery of, any such amendment or
     supplement shall constitute a waiver of any of the conditions set forth in
     Section 6.

                                        9


<PAGE>

          (d)  As soon as practicable, but not later than the Availability Date
     (as defined below), the Company will make generally available to its
     security holders an earnings statement covering a period of at least 12
     months beginning after the Effective Date of the Initial Registration
     Statement (or, if later, the Effective Date of the Additional Registration
     Statement) which will satisfy the provisions of Section 11(a) of the Act.
     For the purpose of the preceding sentence, "Availability Date" means the
     45th day after the end of the fourth fiscal quarter following the fiscal
     quarter that includes such Effective Date, except that, if such fourth
     fiscal quarter is the last quarter of the Company's fiscal year,
     "Availability Date" means the 90th day after the end of such fourth fiscal
     quarter.

          (e)  The Company will furnish to the Managers copies of the
     Registration Statement four of which will be signed and will include all
     exhibits), each preliminary prospectus relating to the International
     Securities, and, until completion of the distribution of the International
     Securities as determined by CSFBL, the International Prospectus and all
     amendments and supplements to such documents, in each case in such
     quantities as CSFBL requests.  The International Prospectus shall be so
     furnished on or prior to 3:00 P.M., New York time, on the business day
     following the later of the execution and delivery of this Agreement or the
     Effective Time of the Initial Registration Statement.  All other such
     documents shall be so furnished as soon as available.  The Company will pay
     the expenses of printing and distributing to the Managers all such
     documents.

          (f)  No action has been or, prior to the completion of the
     distribution of the Offered Securities, will be taken by the Company in any
     jurisdiction outside the United States and Canada that would permit a
     public offering of the Offered Securities, or possession or distribution of
     the International Prospectus, or any amendment or supplement thereto, or
     any related preliminary prospectus issued in connection with the offering
     of the Offered Securities, or any other offering material, in any country
     or jurisdiction where action for that purpose is required.

          (g)  During the period of five years hereafter, the Company will
     furnish to CSFBL and, upon request, to each of the other Managers, as soon
     as practicable after the end of each fiscal year, a copy of its annual
     report to stockholders for such year; and the Company will furnish to CSFBL
     (i) as soon as available, a copy of each report and any definitive proxy
     statement of the Company filed with the Commission under the Securities
     Exchange Act of 1934, as amended (the "Exchange Act"), or mailed to
     stockholders, and (ii) from time to time, such other information concerning
     the Company as CSFBL may reasonably request.

          (h)  The Company will pay all expenses incident to the performance of
     its obligations under this Agreement and will reimburse the Managers (if
     and to the extent incurred by them)  for the filing fee of the National
     Association of Securities Dealers, Inc. relating to the Offered Securities,
     for any travel expenses of the Company's officers and employees and any
     other expenses of the Company in connection with attending or hosting
     meetings with prospective purchasers of the Offered Securities and for
     expenses incurred in distributing preliminary prospectuses and the
     Prospectuses (including any amendments and supplements thereto) to the
     Managers.

                                       10


<PAGE>

          (i)  For a period of 90 days after the date of the initial public
     offering of the Offered Securities, the Company will not offer, sell,
     contract to sell, pledge or otherwise dispose of, directly or indirectly,
     or file with the Commission a registration statement under the Act relating
     to, any additional shares of its Securities or securities convertible into
     or exchangeable or exercisable for any shares of its Securities, or
     publicly disclose the intention to make any such offer, sale, pledge,
     disposal or filing, without the prior written consent of CSFBC, except
     issuances of Securities pursuant to the conversion or exchange of
     convertible or exchangeable securities or the exercise of warrants or
     options, in each case outstanding on the date hereof, grants of employee
     stock options pursuant to the terms of a plan in effect on the date hereof,
     issuances of Securities pursuant to the exercise of such options or
     issuances of Securities pursuant to the Company's dividend reinvestment
     plan.

     6.  CONDITIONS OF THE OBLIGATIONS OF THE MANAGERS.  The obligations of the
several Managers to purchase and pay for the International Firm Securities on
the First Closing Date and the International Optional Securities to be purchased
on each Optional Closing Date will be subject to the accuracy of the
representations and warranties on the part of the Company herein, to the
accuracy of the statements of Company officers made pursuant to the provisions
hereof, to the performance by the Company of its obligations hereunder and to
the following additional conditions precedent:

          (a)  The Managers shall have received a letter, dated the date of
     delivery thereof (which, if the Effective Time of the Initial Registration
     Statement is prior to the execution and delivery of this Agreement, shall
     be on or prior to the date of this Agreement or, if the Effective Time of
     the Initial Registration Statement is subsequent to the execution and
     delivery of this Agreement, shall be prior to the filing of the amendment
     or post-effective amendment to the registration statement to be filed
     shortly prior to such Effective Time), of Deloitte & Touche LLP to the
     effect set forth in Section 6(a) of the Underwriting Agreement.

          (b)  The Managers shall have received a letter, dated the date of
     delivery thereof (which, if the Effective Time of the Initial Registration
     Statement is prior to the execution and delivery of this Agreement, shall
     be on or prior to the date of this Agreement or, if the Effective Time of
     the Initial Registration Statement is subsequent to the execution and
     delivery of this Agreement, shall be prior to the filing of the amendment
     or post-effective amendment to the registration statement to be filed
     shortly prior to such Effective Time), of Price Waterhouse LLP to the
     effect set forth in Section 6(b) of the Underwriting Agreement.

          (c)  If the Effective Time of the Initial Registration Statement is
     not prior to the execution and delivery of this Agreement, such Effective
     Time shall have occurred not later than 10:00 P.M., New York time, on the
     date of this Agreement or such later date as shall have been consented to
     by CSFBL.  If the Effective Time of the Additional Registration Statement
     (if any) is not prior to the execution and delivery of this Agreement, such
     Effective Time shall have occurred not later than 10:00 P.M., New York
     time, on the date of this Agreement or, if earlier, the time either
     Prospectus is printed and distributed to any Manager or U.S. Underwriter,
     or shall have occurred at such later date as shall have been consented to
     by CSFBL.  If the Effective Time of the Initial Registration Statement is
     prior to the execution and delivery of this Agreement, each of the
     Prospectuses shall have been filed with the Commission in accordance with
     the Rules and Regulations and Section 5(a) of this Agreement.  Prior to
     such Closing Date, no stop order suspending the effectiveness of a
     Registration Statement shall have been issued

                                       11


<PAGE>

     and no proceedings for that purpose shall have been instituted or, to the
     knowledge of the Company or the Managers, shall be contemplated by the
     Commission.

          (d)  Subsequent to the execution and delivery of this Agreement, there
     shall not have occurred (A) a change in U.S. or international financial,
     political or economic conditions or currency exchange rates or exchange
     controls as would, in the judgment of CSFBL, be likely to prejudice
     materially the success of the proposed issue, sale or distribution of the
     International Securities, whether in the primary market or in respect of
     dealings in the secondary market, or (B)(i) any change, or any development
     or event involving a prospective change, in the condition (financial or
     other), business, properties or results of operations of the Company or its
     subsidiaries which, in the judgment of CSFBL, is material and adverse and
     makes it impractical or inadvisable to proceed with completion of the
     public offering or the sale of and payment for the International
     Securities; (ii) any downgrading in the rating of any debt securities of
     the Company by any "nationally recognized statistical rating organization"
     (as defined for purposes of Rule 436(g) under the Act), or any public
     announcement that any such organization has under surveillance or review
     its rating of any debt securities of the Company (other than an
     announcement with positive implications of a possible upgrading, and no
     implication of a possible downgrading, of such rating); (iii) any
     suspension or limitation of trading in securities generally on the New York
     Stock Exchange, or any setting of minimum prices for trading on such
     exchange, or any suspension of trading of any securities of the Company on
     any exchange or in the over-the-counter market; (iv) any banking moratorium
     declared by U.S. Federal or New York authorities; or (v) any outbreak or
     escalation of major hostilities in which the United States is involved, any
     declaration of war by the United States Congress or any other substantial
     national or international calamity or emergency if, in the judgment of
     CSFBL, the effect of any such outbreak, escalation, declaration, calamity
     or emergency makes it impractical or inadvisable to proceed with completion
     of the public offering or the sale of and payment for the International
     Securities.

          (e)  The Managers shall have received an opinion, dated such Closing
     Date, of Sheppard, Mullin, Richter & Hampton LLP, counsel for the Company,
     to the effect set forth in Section 6(d) of the Underwriting Agreement.

          (f)  The Managers shall have received an opinion, dated such Closing
     Date, of Richard R. Molleur, Corporate Vice President and General Counsel
     of the Company, to the effect set forth in Section 6(e) of the Underwriting
     Agreement.

          (g)  The Managers shall have received from Latham & Watkins, counsel
     for the Managers, such opinion or opinions, dated such Closing Date, with
     respect to the incorporation of the Company, the validity of the Offered
     Securities delivered on such Closing Date, the Registration Statement, the
     Prospectuses and other related matters as the Managers may require, and the
     Company shall have furnished to such counsel such documents as they request
     for the purpose of enabling them to pass upon such matters.

          (h)  The Managers shall have received a certificate, dated such
     Closing Date, of the President or any Vice President and a principal
     financial or accounting officer of the Company in which such officers, to
     the best of their knowledge after reasonable investigation, shall state
     that: the representations and warranties of the Company in this Agreement
     are true and correct;

                                       12

     the Company has complied with all agreements and satisfied all conditions
     on its part to be performed or satisfied hereunder at or prior to such
     Closing Date; no stop order suspending the effectiveness of any
     Registration Statement has been issued and no proceedings for that purpose
     have been instituted or are contemplated by the Commission; the Additional
     Registration Statement (if any) satisfying the requirements of
     subparagraphs (1) and (3) of Rule 462(b) was filed pursuant to Rule 462(b),
     including payment of the applicable filing fee in accordance with Rule
     111(a) or (b) under the Act, prior to the time either Prospectus was
     printed and distributed to any Manager or U.S. Underwriter; and, subsequent
     to the respective dates of the most recent financial statements in the
     Prospectuses, there has been no material adverse change, nor any
     development or event involving a prospective material adverse change, in
     the condition (financial or other), business, properties or results of
     operations of the Company and its subsidiaries taken as a whole except as
     set forth in or contemplated by the Prospectuses or as described in such
     certificate.

          (i)  The Managers shall have received a letter, dated such Closing
     Date, of Deloitte & Touche LLP which meets the requirements of
     subsection (a) of this Section, except that the specified date referred to
     in such subsection will be a date not more than three days prior to such
     Closing Date for the purposes of this subsection.

          (j)  The Managers shall have received a letter, dated such Closing
     Date, of Deloitte & Touche LLP which meets the requirements of
     subsection (b) of this Section, except that the specified date referred to
     in such subsection will be a date not more than three days prior to such
     Closing Date for the purposes of this subsection.

          (k)  On such Closing Date, the U.S. Underwriters shall have purchased
     the U.S. Firm Securities or the U.S. Optional Securities, as the case may
     be, pursuant to the Underwriting Agreement.

     The Company will furnish the Managers with such conformed copies of such
opinions, certificates, letters and documents as the Managers reasonably
request.  CSFBL may in its sole discretion waive on behalf of the Managers
compliance with any conditions to the obligations of the Managers hereunder,
whether in respect of an Optional Closing Date or otherwise.

     7.  INDEMNIFICATION AND CONTRIBUTION.  (a)  The Company will indemnify and
hold harmless each Manager against any losses, claims, damages or liabilities,
joint or several, to which such Manager may become subject, under the Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon any untrue statement or alleged
untrue statement of any material fact contained in any Registration Statement,
either of the Prospectuses, or any amendment or supplement thereto, or any
related preliminary prospectus, or arise out of or are based upon the omission
or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, and will
reimburse each Manager for any legal or other expenses reasonably incurred by
such Manager in connection with investigating or defending any such loss, claim,
damage, liability or action as such expenses are incurred; provided, however,
that the Company will not be liable in any such case to the extent that any such
loss, claim, damage or liability arises out of or is based upon an untrue
statement or alleged untrue statement in or omission or alleged omission from
any of such documents in reliance upon and in conformity with written
information furnished to the Company by any Manager through CSFBL specifically
for use therein, it

                                       13


<PAGE>

being understood and agreed that the only information furnished by any Manager
consists of the information described as such in subsection (b) below.

     (b)  Each Manager will severally and not jointly indemnify and hold
harmless the Company against any losses, claims, damages or liabilities to which
the Company may become subject, under the Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon any untrue statement or alleged untrue statement of any
material fact contained in any Registration Statement, either of the
Prospectuses, or any amendment or supplement thereto, or any related preliminary
prospectus, or arise out of or are based upon the omission or the alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, in each case to the
extent, but only to the extent, that such untrue statement or alleged untrue
statement or omission or alleged omission was made in reliance upon and in
conformity with written information furnished to the Company by such Manager
through CSFBL specifically for use therein, and will reimburse any legal or
other expenses reasonably incurred by the Company in connection with
investigating or defending any such loss, claim, damage, liability or action as
such expenses are incurred, it being understood and agreed that the only such
information furnished by any Manager consists of the following information in
the International Prospectus furnished on behalf of each Manager: the last
paragraph at the bottom of the cover page concerning the terms of the offering
by the Managers, the legend concerning over-allotments and stabilizing on the
inside front cover page and the concession and reallowance figures appearing in
the fifth paragraph under the caption "Subscription and Sale."

     (c)  Promptly after receipt by an indemnified party under this Section of
notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under
subsection (a) or (b) above, notify the indemnifying party of the commencement
thereof; but the omission so to notify the indemnifying party will not relieve
it from any liability which it may have to any indemnified party otherwise than
under subsection (a) or (b) above.  In case any such action is brought against
any indemnified party and it notifies the indemnifying party of the commencement
thereof, the indemnifying party will be entitled to participate therein and, to
the extent that it may wish, jointly with any other indemnifying party similarly
notified, to assume the defense thereof, with counsel satisfactory to such
indemnified party (who shall not, except with the consent of the indemnified
party, be counsel to the indemnifying party), and after notice from the
indemnifying party to such indemnified party of its election so to assume the
defense thereof, the indemnifying party will not be liable to such indemnified
party under this Section for any legal or other expenses subsequently incurred
by such indemnified party in connection with the defense thereof other than
reasonable costs of investigation.  No indemnifying party shall, without the
prior written consent of the indemnified party, effect any settlement of any
pending or threatened action in respect of which any indemnified party is or
could have been a party and indemnity could have been sought hereunder by such
indemnified party unless such settlement includes an unconditional release of
such indemnified party from all liability on any claims that are the subject
matter of such action.

     (d)  If the indemnification provided for in this Section is unavailable or
insufficient to hold harmless an indemnified party under subsection (a) or (b)
above, then each indemnifying party shall contribute to the amount paid or
payable by such indemnified party as a result of the losses, claims, damages or
liabilities referred to in subsection (a) or (b) above (i) in such proportion as
is appropriate to reflect the relative benefits received by the Company on the
one hand and the Managers on the other from the offering of the International
Securities or (ii) if the allocation provided by clause (i) above is

                                       14


<PAGE>

not permitted by applicable law, in such proportion as is appropriate to reflect
not only the relative benefits referred to in clause (i) above but also the
relative fault of the Company on the one hand and the Managers on the other in
connection with the statements or omissions which resulted in such losses,
claims, damages or liabilities as well as any other relevant equitable
considerations.  The relative benefits received by the Company on the one hand
and the Managers on the other shall be deemed to be in the same proportion as
the total net proceeds from the offering of the International Securities (before
deducting expenses) received by the Company bear to the total underwriting
discounts and commissions received by the Managers.  The relative fault shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Company or the Managers
and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such untrue statement or omission.  The amount
paid by an indemnified party as a result of the losses, claims, damages or
liabilities referred to in the first sentence of this subsection (d) shall be
deemed to include any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating or defending any action or
claim which is the subject of this subsection (d).  Notwithstanding the
provisions of this subsection (d), no Manager shall be required to contribute
any amount in excess of the amount by which the total price at which the
International Securities underwritten by it and distributed to the public were
offered to the public exceeds the amount of any damages which such Manager has
otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission.  No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation.  The Managers' obligations in this subsection (d) to
contribute are several in proportion to their respective underwriting
obligations and not joint.

     (e)  The obligations of the Company under this Section shall be in addition
to any liability which the Company may otherwise have and shall extend, upon the
same terms and conditions, to each person, if any, who controls any Manager
within the meaning of the Act or the Exchange Act; and the obligations of the
Managers under this Section shall be in addition to any liability which the
respective Managers may otherwise have and shall extend, upon the same terms and
conditions, to each director of the Company, to each officer of the Company who
has signed a Registration Statement and to each person, if any, who controls the
Company within the meaning of the Act or the Exchange Act.

     8.  DEFAULT OF MANAGERS.  If any Manager or Managers default in their
obligations to purchase International Securities hereunder on either the First
or any Optional Closing Date and the aggregate number of shares of International
Securities that such defaulting Manager or Managers agreed but failed to
purchase does not exceed 10% of the total number of shares of International
Securities that the Managers are obligated to purchase on such Closing Date,
CSFBL may make arrangements satisfactory to the Company for the purchase of such
International Securities by other persons, including any of the Managers, but if
no such arrangements are made by such Closing Date the non-defaulting Managers
shall be obligated severally, in proportion to their respective commitments
hereunder, to purchase the International Securities that such defaulting
Managers agreed but failed to purchase on such Closing Date.  If any Manager or
Managers so default and the aggregate number of shares of International
Securities with respect to which such default or defaults occur exceeds 10% of
the total number of shares of International Securities that the Managers are
obligated to purchase on such Closing Date and arrangements satisfactory to
CSFBL and the Company for the purchase of such International Securities by other
persons are not made within 36 hours after such default, this Agreement will
terminate without liability on the part of any non-defaulting Manager or the
Company, except as provided in Section 9

                                       15


<PAGE>

(provided that if such default occurs with respect to International Optional
Securities after the First Closing Date, this Agreement will not terminate as to
the International Firm Securities or any International Optional Securities
purchased prior to such termination).  As used in this Agreement, the term
"Manager" includes any person substituted for a Manager under this Section.
Nothing herein will relieve a defaulting Manager from liability for its default.

     9.  SURVIVAL OF CERTAIN REPRESENTATIONS AND OBLIGATIONS.  The respective
indemnities, agreements, representations, warranties and other statements of the
Company or its officers and of the several Managers set forth in or made
pursuant to this Agreement will remain in full force and effect, regardless of
any investigation, or statement as to the results thereof, made by or on behalf
of any Manager, the Company or any of their respective representatives, officers
or directors or any controlling person, and will survive delivery of and payment
for the International Securities.  If this Agreement is terminated pursuant to
Section 8 or if for any reason the purchase of the International Securities by
the Managers is not consummated, the Company shall remain responsible for the
expenses to be paid or reimbursed by it pursuant to Section 5 and the respective
obligations of the Company and the Managers pursuant to Section 7 shall remain
in effect and if any International Securities have been purchased hereunder the
representations and warranties in Section 2 and all obligations under Section 5
shall also remain in effect.  If the purchase of the International Securities by
the Managers is not consummated for any reason other than solely because of the
termination of this Agreement pursuant to Section 8 or the occurrence of any
event specified in Section 6(d)(A) or clause (iii), (iv), or (v) of
Section 6(d)(B), the Company will reimburse the Managers for all out-of-pocket
expenses (including fees and disbursements of counsel) reasonably incurred by
them in connection with the offering of the International Securities.

     10.  NOTICES.  All communications hereunder will be in writing and, if sent
to the Managers, will be mailed, delivered or telexed and confirmed to CSFBL at
One Cabot Square, London E14 4QJ England, Attention:  Company Secretary, or, if
sent to the Company, will be mailed, delivered or telegraphed and confirmed to
it at Northrop Grumman Corporation, 1840 Century Park East, Los Angeles, CA
90067, Attention:  Richard B. Waugh, Jr., Corporate Vice President and Chief
Financial Officer; provided, however, that any notice to a Manager pursuant to
Section 7 will be mailed, delivered or telexed and confirmed to such Manager.

     11.  SUCCESSORS.  This Agreement will inure to the benefit of and be
binding upon the parties hereto and their respective successors and the officers
and directors and controlling persons referred to in Section 7, and no other
person will have any right or obligation hereunder.

     12.  REPRESENTATION OF MANAGERS.  CSFBL will act for the several Managers
in connection with this financing, and any action under this Agreement taken by
CSFBL will be binding upon all the Managers.

     13.  COUNTERPARTS.  This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original, but all such
counterparts shall together constitute one and the same Agreement.

     14.  APPLICABLE LAW.  THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES
OF CONFLICTS OF LAWS.

                   Re: REGISTRATION STATEMENT ON FORM S-3

Dear Sirs:

     You have filed with the Securities and Exchange Commission a 
registration statement on Form S-3 (the "Registration Statement") in 
connection with the registration under the Securities Act of 1933, as 
amended, of 8,050,000 shares of Common Stock and a like number of 
Common Stock Purchase Rights (the "Securities") of Northrop Grumman 
Corporation, a Delaware corporation (the "Company").

     In connection with the furnishing of our opinion to you concerning this 
matter, we have examined such corporate records and other documents as we 
have deemed relevant and necessary as a basis for the opinions set forth 
herein. In such examinations, we have assumed the genuineness of all 
signatures and the authenticity of all documents submitted to us as certified 
or photostatic copies.

     We have also examined the Registration Statement and are familiar with 
the additional proceedings proposed to be taken by you in connection with the 
sale of the Securities.

     On the basis of the foregoing, and in reliance thereon, and after 
consideration of such matters and laws as we deem applicable
 and relevant, we 
are of the opinion that the Securities, when sold in the manner set forth in 
the Registration Statement, will be legally and validly issued, fully paid 
and nonassessable.

     We consent to the use of this opinion as an exhibit to the Registration 
Statement, and we further consent to the use of our name under the caption 
"Legal Matters" in the Registration Statement and in the Prospectus which is 
a part thereof.

                                   Respectfully submitted,


                                   SHEPPARD, MULLIN, RICHTER &

                    FILING OF REGISTRATION STATEMENT ON FORM S-3

KNOW ALL MEN BY THESE PRESENTS, that each of the undersigned directors and
