INDEPENDENT AUDITORS' REPORT

To the Administrative Committee of the
 Northrop Grumman Commercial Aircraft Division
 Salaried Savings and Investment Plan:

We have audited the accompanying statements of net assets available for plan
benefits of the Northrop Grumman Commercial Aircraft Division Salaried Savings
and Investment Plan (the "Plan") as of December 31, 1998 and 1997, and the
related statements of changes in net assets available for plan benefits for the
year ended December 31, 1998. These financial statements are the responsibility
of the Plan's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about 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.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such financial statements present fairly, in all material
respects, the net assets available for plan benefits of the Plan at December 31,
1998 and 1997, and the changes in net assets available for plan benefits for the
year ended December 31, 1998 in conformity with generally accepted accounting
principles.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedules of assets held
for investment purposes at December 31, 1998 and reportable transactions for the
year then ended are presented for the purpose of additional analysis and are not
a required part of the basic financial statements but are supplementary
information required by the Department of Labor's Rules and Regulations for
Reporting and Disclosure under the Employee Retirement Income Security Act of
1974. The supplemental information by fund in the statement of changes in net
assets available for plan benefits is presented for the purpose of additional
analysis rather than to present the changes in net assets available for plan
benefits of the individual funds. The supplemental schedules and supplemental
information by fund are the responsibility of the Plan's management. Such
supplemental schedules and supplemental information by fund have been subjected
to the auditing procedures applied in our audits of the basic financial
statements and, in our opinion, are fairly stated in all material respects when
considered in relation to the basic financial statements taken as a whole.

-6- NORTHROP GRUMMAN COMMERCIAL AIRCRAFT DIVISION SALARIED SAVINGS AND INVESTMENT PLAN NOTES TO FINANCIAL STATEMENTS YEARS ENDED DECEMBER 31, 1998 AND 1997 - -------------------------------------------------------------------------------- A. DESCRIPTION OF THE PLAN The following description of the Northrop Grumman Commercial Aircraft Division Salaried Savings and Investment Plan (the "Plan") provides only general information. Participants should refer to the Plan agreement for a more complete description of the Plan's provisions. General- The Plan is a defined contribution profit sharing plan with a 401(k) feature. Effective August 31, 1992, the sale of certain assets and liabilities of the Aircraft and Missiles Division of the LTV Aerospace and Defense Company was completed. The LTV Corporation sold the Aircraft Division to the Carlyle Group and Northrop Corporation, and the Vought Aircraft Company ("Vought") was established. The account balances of former Aircraft Division participants in the LTV Capital Accumulation Plan (the "Predecessor Plan") were transferred to the Vought Aircraft Salaried Capital Appreciation Plan effective August 31, 1992. Effective August 31, 1994, Northop Grumman Corporation (the "Company") purchased all of the Carlyle Group's interest in Vought, and Vought became a wholly owned subsidiary of Northrop Grumman Corporation. Effective July 1, 1995, the Plan was amended to change the name to the Vought Aircraft Salaried Savings and Investment Plan. Effective October 1, 1997, the Plan was amended to change the name to Northrop Grumman Commercial Aircraft Division Salaried Savings and Investment Plans. Contributions - The Plan offers participants a choice between the type of contributions they can make, and such contributions may be between 2% and 18% of eligible compensation in increments of 1%. A participant can elect tax-deferred (before-tax) contributions, after-tax contributions, or a combination of both. An active participant may change the percentage of his or her contributions. Contributions are subject to certain limitations. The Company's matching contribution is as follows: Employee Contribution Company Match First 2% of eligible compensation 100% Next 2% of eligible compensation 50% Next 4% of eligible compensation 25% Contributions over 8% 0% -7- Participant Accounts - A separate account is maintained for each participant. Each participant's account is credited with the participant's contributions, the Company's matching contributions, and the proportionate share of the Plan's earnings and administrative expenses. Allocations are based on the participants' account balances, as defined in the Plan agreement. The benefit to which a participant is entitled is the benefit that can be provided from the participant's vested account. Vesting - Plan participants are fully vested (100%) at all times in the balance of their accounts (both employee and employer contributions). Investment Options - Upon enrollment in the Plan, each participant may direct that his or her employee contributions and Company matching contributions, in 1% increments, be invested in any of the following investment funds: Northrop Grumman Master Trust - Stable Value Fund Frank Russell Trust Company Fund - Equity I Fund Frank Russell Trust Company Funds - Global Balanced Fund Frank Russell Trust Company Funds - Global Equity Fund T. Rowe Price Company - Growth & Income Fund Northrop Grumman Corporation common stock Participants may change their investment options on a daily basis. Participant Notes Receivable - Participants may borrow from their fund accounts a minimum of $1,000 up to a maximum equal to the lesser of $50,000 or 50% of their account balance. A participant may not have more than one outstanding loan at any given time. Loans will be prorated across all investment funds and are secured by the balance in the participant's account. The interest rate is fixed on the first business day of each month at the prime rate of the Plan's trustee plus 1%. Repayments are made from weekly payroll deductions (for active employees) or other method approved by the administrative committee. The maximum loan period is five years, or ten years for a loan used to acquire a dwelling that is to be the principal residence of the participant. Loans may be prepaid in full; partial prepayments are not permitted. Payment of Benefits - Upon termination of service, a participant may elect to receive a lump-sum amount equal to the value of his or her account balance. A participant may also delay his or her lump-sum payment until the participant's normal retirement date if the account balance exceeds $5,000. B. SIGNIFICANT ACCOUNTING POLICIES Basis of Accounting - The financial statements of the Plan are prepared under the accrual method of accounting. -8- Use of Estimates - The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and changes therein, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates. Investment Valuation and Income Recognition - In the accompanying statements of net assets available for plan benefits, the Plan's investments are stated at fair value, except for the Plan's investment in the Stable Value Fund, which is valued at contract value (see Note D). Investments in the Equity I Fund, Global Balanced Fund, Global Equity Fund, and Growth & Income Fund (the "Funds") are valued at quoted market prices which represent the net asset values of shares held by the Plan at year-end. Northrop Grumman common stock is valued at its quoted market price. Loans receivable from plan participants are valued at cost, which approximates fair value. Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date. Payment of Benefits - Benefits are recorded when paid. As of December 31, 1998 and 1997, benefits payable to participants are approximately $14,000 and $3,000, respectively. C. INVESTMENTS Except for its insurance and investment contracts (see Note D), the Plan's investments as of December 31, 1998 and 1997, are stated at fair value as determined by quoted market prices. On January 1, 1998, Northrop Grumman Corporation pooled all of the insurance and investment contracts for the Northrop Grumman Corporation Savings and Investment Plan Master Trust, the Northrop Grumman Master Trust, and the contracts held by the Northrop Grumman Electronic Sensorws and Systems Division Savings and Investment Program into the Northrop Grumman Stable Value Master Trust (the "Master Trust"). Investments held at contract value in the Master Trust as of December 31, 1998 and in the Northop Grumman Master Trust as of December 31, 1997, are as follows (in thousands): 1998 1997 Guaranteed and Bank Investment Contracts $1,298,790 $ 61,254 Northrop Retirement Savings Temporary Investment Fund 60,090 5,339 Accrued Income 113 15 ---------- --------- Total $1,358,993 $ 66,608 -9- The Plan's investment in the Master Trust as of December 31, 1998, and in the Northrop Grumman Master Trust as of December 31, 1997, is as follows (in thousands): 1998 1997 Contract Value of Guaranteed and Bank Investment Contracts $ 72,188 $ 56,187 Net securities sales pending settlement 1,010 274 Total $ 73,198 $ 56,461 Percentage of ownership 5.39% 84.77% Investment income in the Stable Value Master Trust was $91,158,197 for the year ended December 31, 1998. Investment income in the Northrop Grumman Master Trust for the year ended December 31, 1997 was $4,537.000. D. INVESTMENT CONTRACTS WITH INSURANCE COMPANIES All investment and insurance contracts held by the Master Trust are considered to be fully benefit-responsive and, therefore, are reported at contract value. Contract value represents contributions made under the contract, plus interest at the contract rate, less withdrawals and administrative expenses. The following information is disclosed for the investment and insurance contracts within the Master Trust as of December 31, 1998, and the Northrop Grumman Master Trust as of December 31, 1997 (in millions): 1998 1997 Contract value of assets $1,299 $ 61.3 Fair value of assets $1,343 $ 62.2 Crediting interest rate of assets at December 31 7.08 % 6.62 % Average yield on assets for the 12 months ending December 31 7.09 % 7.39 % Duration 2.58 years 2.05 years E. INCOME TAX STATUS The Internal Revenue Service ruled on December 9, 1996 that the Plan qualifies under Section 401(a) of the Internal Revenue Code ("IRC"), and therefore, the related trust is not subject to tax under the present income tax law. Once qualified, the Plan is required to operate in conformity with the IRC to maintain its qualification. Northrop Grumman Corporation is not aware of any course of action or series of events that have occurred that might adversely affect the Plan's qualified status. F. TRANSACTIONS WITH PARTIES-IN-INTEREST In management's opinion, fees paid for services rendered by parties-in-interest during 1998 and 1997 were based upon customary and reasonable rates for such services. ****** -11- NORTHROP GRUMMAN COMMERCIAL AIRCRAFT DIVISION SALARIED SAVINGS AND INVESTMENT PLAN ITEM 27a - ASSETS HELD FOR INVESTMENT PURPOSES DECEMBER 31, 1998 - --------------------------------------------------------------------------------
