                         REPORT OF INDEPENDENT AUDITORS





To the Participants and the Board of Administration of
The TRW Canada Stock Savings Plan

We have  audited  the  statements  of  financial  condition  of the Stock  Fund,
Employees' Profit Sharing Plan Fund and Registered  Retirement Savings Plan Fund
[collectively,  representing  the funds of The TRW Canada Stock Savings Plan] as
at December  31,  2002 and 2001 and the related  statements  of  operations  and
changes in fund equity for these funds for the years then ended. These financial
statements   are  the   responsibility   of  the   company's   management.   Our
responsibility  is to express an opinion on these financial  statements based on
our audits.

We conducted our audits in accordance with Canadian  generally accepted auditing
standards.  Those standards  require that we plan and perform an audit to obtain
reasonable  assurance  whether  the  financial  statements  are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management, as well as evaluating the overall financial statement presentation.

In our opinion,  these  financial  statements  present  fairly,  in all material
respects,  the financial  condition of the funds of The TRW Canada Stock Savings
Plan as at December  31, 2002 and 2001 and the results of their  operations  and
the changes in fund equity for the years then ended in accordance  with Canadian
generally accepted accounting principles.

1. GENERAL PLAN PROVISIONS

The TRW Canada Stock  Savings Plan [the "Plan"] is a qualified  employee  profit
sharing and retirement  savings plan sponsored by TRW Canada  Limited.  The Plan
was originally  established  effective  January 1, 1968 as a stock savings plan.
Effective  January 1, 1990, the Plan was amended to immediately  vest TRW Canada
Limited's  contributions  and the group retirement  savings portion was added to
the Plan.  The  eligibility  of employees to participate in the Plan is based on
the provisions as included in the Plan document. A participant may join the Plan
upon becoming a permanent part-time or full-time employee. The provisions of the
Plan require  certain  employees  to have been  employed for a period of 90 days
before joining the Plan.

The Plan's assets are held by Clarica Trust as Trustee and  administrator of the
Plan.

Effective  December 11, 2002, TRW Inc.  ["TRW"] was acquired by Northrop Grumman
Corporation  ["NGC"] and TRW shares held in the Plan were  converted into shares
of NGC  common  stock  based on a ratio of 0.5357  NGC share per TRW  share.  In
connection  with the  acquisition of TRW by NGC, the Plan was amended to provide
that any NGC common stock held in the Plan on March 1, 2003 would be distributed
to participants in the form of share certificates.

The investment programs of the Plan are as follows:

Participant contributions

Upon  enrolment or  re-enrolment,  each  participant  directs that his/her basic
contributions  [computed in increments  of one percent,  from one percent to six
percent  of  qualifying   compensation]  are  to  be  invested  in  a  range  of
professionally managed funds with different objectives,  risk factors and return
expectations.  A participant may, at any time, change his/her contribution rate,
temporarily suspend  contributions,  the way he/she invests future contributions
or  existing  assets  at any  time,  at no cost.  If a  participant  temporarily
suspends  contributions,  TRW Canada Limited's  matching  contributions [see TRW
Canada Limited's contributions below] are also temporarily suspended.

A  participant  may make cash  withdrawals  from  his/her  accounts at any time.
However,  if the participant  withdraws his/her basic contribution or TRW Canada
Limited's  matching   contribution  made  on  or  after  January  1,  2003,  the
participant  will not be able to  contribute  to the Plan or receive  TRW Canada
Limited's matching contribution for a period of three months.

                                                                               1

TRW Canada Limited's contributions

current  or  accumulated  earnings,  an amount  equal to 50% of the  participant
contributions  [to a maximum of 3% of the  participant's  compensation] for such
month. TRW Canada Limited's contributions vest immediately.

All TRW Canada Limited's cash contributions were invested in TRW stock purchased
on the open  market  up until  December  11,  2002 at which  point  the  sponsor
contributions were directed to Clarica Perigee Axis Cash Fund NR.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

These  financial  statements  have been  prepared in  accordance  with  Canadian
generally  accepted   accounting   principles,   within  the  framework  of  the
significant accounting policies summarized below:

Basis of accounting

The accompanying financial statements have been prepared on the accrual basis of
accounting.

Investment valuation and income recognition

All investments are recorded at fair market value based on quoted market prices.
Purchase and sale transactions are recorded on a settlement date basis. Interest
income is recorded on the accrual basis. Unrealized appreciation or depreciation
of  investments  is the  difference  between the  current  value and the cost of
investments.  The realized gain or loss on investments is the difference between
the proceeds received and the average cost of investments sold.

Payment of benefits

Benefit payments are recorded when paid.

Gains or losses on investments

The realized  gains or losses on  disposition  or transfer of an  investment  is
determined from the market value of the investment at the date of disposition or
transfer and the average cost base of that specific pool of investments prior to
the disposition or transfer.

Unrealized  gains or losses  are  determined  as the net effect of the change in
appreciation  (depreciation) of investments from January 1 to December 31, based
on market value and the average cost base of each investment at those respective
dates.

Income recognition

Dividend income is recognized as earned.

Interest income is recognized as it is earned  consistent with the accrual basis
of accounting.


                                                                               3

3. INCOME TAXES

The Plan is exempt from Canadian  federal  income taxes under the  provisions of
the Income Tax Act (Canada) [the "Act"].  Federal income tax consequences to the
participants  under the Plan are as  provided in the Act.  TRW Canada  Limited's
contributions are taxable to the participants as is the income and all post-1971
capital  gains,  less  post-1971  capital  losses of the Plan,  all of which are
allocated to the  participants  by the Trustee  during the year,  whether or not
such amounts are paid to the  participants  by the Trustee  during the year. The
amount of foreign non-business income taxes paid on foreign source income by the
trusts  under the Plan for the year is allocated to and deemed to have been paid
by the participants  for Canadian federal income tax purposes.  Participants who
are  non-resident  taxpayers are subject to special  rules  depending on whether
they  have  performed  duties  in  Canada  during  the year and are  subject  to
withholding tax on amounts paid or credited to them under the Plan.

4. RELATED PARTY TRANSACTIONS

All expenses related to the Plan are paid by TRW Canada Limited.

5. STATEMENT DISCLOSURES

The costs of the investments have not been shown  parenthetically as cost is not
tracked or disclosed by the Trustee when reporting to us.

The realized and unrealized gains and losses have not been disclosed  separately
as the Trustee does not segregate this information when reporting to us.

6. COMPARATIVE FINANCIAL STATEMENTS

The  comparative  financial  statements have been  reclassified  from statements
previously  presented  to  conform  to the  presentation  of the 2002  financial
statements.
