REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Participants and Administrator of the L-3 Communications Master Savings Plan: We have audited the accompanying statements of net assets available for benefits of the L-3 Communications Master Savings Plan (the "Plan") as of December 31, 2003 and 2002, and the related statement of changes in net assets available for benefits for the year ended December 31, 2003. 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 of these statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). 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, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2003 and 2002, and the changes in net assets available for benefits for the year ended December 31, 2003 in conformity with accounting principles generally accepted in the United States of America. Our audits were conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental Schedule of Nonexempt Transactions, which is presented for the purpose of additional analysis and is not a required part of the basic financial statements, is 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 schedule is the responsibility of the Plan's management. The supplemental schedule has been subjected to the auditing procedures applied in the audit of the basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole. /s/ PricewaterhouseCoopers LLP New York, New York June 28, 2004 2 L-3 COMMUNICATIONS MASTER SAVINGS PLAN STATEMENT OF NET ASSETS AVAILABLE FOR BENEFITS DECEMBER 31, 2003 (IN THOUSANDS) Non- Participant Participant Directed Directed Total -------- -------- -------- Assets: Investment in Master Trust $891,597 $ 64,162 $955,759 Contributions receivable: Participants 1,268 -- 1,268 Company 521 2,827 3,348 -------- -------- -------- Net assets available for benefits $893,386 $ 66,989 $960,375 ======== ======== ======== See Notes to Financial Statements 3 L-3 COMMUNICATIONS MASTER SAVINGS PLAN STATEMENT OF NET ASSETS AVAILABLE FOR BENEFITS DECEMBER 31, 2002 (IN THOUSANDS) Non- Participant Participant Directed Directed Total -------- -------- -------- Assets: Investment in Master Trust $688,116 $ 28,482 $716,598 Contributions receivable: Participants 1,303 -- 1,303 Company 5 618 623 -------- -------- -------- Net assets available for benefits $689,424 $ 29,100 $718,524 ======== ======== ======== See Notes to Financial Statements 4 L-3 COMMUNICATIONS MASTER SAVINGS PLAN STATEMENT OF CHANGES IN NET ASSETS AVAILABLE FOR BENEFITS FOR THE YEAR ENDED DECEMBER 31, 2003 (IN THOUSANDS) Non- Participant Participant Directed Directed Total --------- --------- --------- Contributions: Participant $ 89,211 $ -- $ 89,211 Company 4,860 40,204 45,064 Rollover 14,356 -- 14,356 Investment income: Appreciation in the fair value of investment in Master Trust 107,940 7,767 115,707 Interest and dividends 16,071 51 16,122 Interest (participant loans) 1,403 1 1,404 Transfers from non-participant directed funds to participant directed funds 7,865 (7,865) -- Transfers from other plans 22,186 -- 22,186 Benefit payments (59,676) (2,131) (61,807) Administrative expenses (254) (138) (392) --------- --------- --------- Net increase 203,962 37,889 241,851 Net assets available for benefits Beginning of period 689,424 29,100 718,524 --------- --------- --------- Net assets available for benefits End of period $ 893,386 $ 66,989 $ 960,375 ========= ========= ========= See Notes to Financial Statements 5 L-3 COMMUNICATIONS MASTER SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS 1. PLAN DESCRIPTION General The following description of the L-3 Communications Master Savings Plan (the "Plan") provides only general information. Participants should refer to the plan document for a more complete description of the Plan's provisions. The Plan is a defined contribution 401(k) plan and is administered by the Benefit Plan Committee ("Plan Administrator") appointed by L-3 Communications Corporation (the "Company"). The Plan is designed to provide eligible employees with tax advantaged long-term savings for retirement. The Plan covers employees of 44 locations of the Company (See note 3 for a complete listing.) and is subject to the provisions of the Employee Retirement Income Security Act of 1974 ("ERISA"). Participants may direct their investment to a combination of mutual funds, which are held in the L-3 Communications Master Savings Plan Trust (the "Master Trust"), managed by Fidelity Management Trust Company ("FMTC"), as Trustee. Contributions Generally, full time and part time employees who are scheduled to complete a minimum of 20 hours of service weekly are eligible to participate in the Plan, as of their date of hire. Each eligible employee wishing to participate in the Plan must elect to authorize pre-tax and/or post-tax contributions by payroll deduction. Participants may contribute from 1% to 18% of total compensation, as defined. A participant may elect to increase, decrease, suspend or resume contributions at any time. The election will become effective as soon as administratively possible as of the first day of the payroll period elected. The Internal Revenue Code ("IRC") of 1986, as amended, limited the maximum amount an employee may contribute on a pre-tax basis in 2003 to $12,000 for participants under 50 years of age and $14,000 for participants 50 years of age and over. Participants are 100% vested in their contributions and earnings thereon. Participant Accounts Each participant's account is credited with the participant's contribution and allocations of (a) the Company's contribution and (b) the Plan's earnings, and may be charged with certain administrative expenses. Allocations are based on participant earnings or account balances, as defined. The benefit to which a participant is entitled is the benefit that can be provided from the participant's vested account. Master Trust Investment Options All non-participant directed employer contributions must be initially invested in the L-3 Stock Fund, and may not be invested in other Master Trust investment options until two years after the end of the plan year in which the employer contribution is made.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Investment in Master Trust Investment assets of the Plan are maintained in the Master Trust administered by FMTC, as Trustee. The Plan participates in the Master Trust along with all the assets of the Aviation Communications & Surveillance Systems 401(k) Plan and the SPD Technologies Defined Contribution Retirement Plan, collectively referred to as the Participating Plans. During the year ended December 31, 2003, the SPD Technologies Defined Contribution Retirement Plan was merged into the Plan. The investment in the Master Trust represents the Plan's proportionate share of assets held in the Master Trust. The assets consist of units of funds that are maintained by FMTC. (See Note 1 for a description of the fund options.) Contributions, benefit payments and certain administrative expenses are specifically identified to the Plan. Valuation of Investments The investment in the Master Trust is stated at fair value. The L-3 Stock Fund is a unitized fund whose underlying assets consist primarily of L-3 Holdings common stock. Shares of L-3 Holdings common stock are valued at the last reported quoted market price of a share on the last trading day of the year. Investments in mutual funds are valued at quoted market prices, which represent the net asset value per share as reported by Fidelity Management and Research Company. Participant loans are valued at cost, which approximates fair value. Basis of Accounting The financial statements of the Plan are prepared under the accrual method of accounting. 8 L-3 COMMUNICATIONS MASTER SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS- CONTINUED Investment Transactions and Investment Income Investment transactions are accounted for on a trade-date basis. Dividend income is recorded on the ex-dividend date. Interest income is recorded on an accrual basis. Gains and losses on sales of investment securities are determined based on the average cost method. Net appreciation in the fair value of the Plan's investment, as shown in the Statement of Changes in Net Assets Available for Benefits, consists of the Plan's proportionate share of realized gains or losses and unrealized appreciation or depreciation on those investments. The net appreciation and interest and dividends are allocated to the L-3 Participating Plans based upon the relationship of each L-3 Participating Plan's respective monthly balances in the investment pool to the total investment pool of the Master Trust, as determined at the beginning of each month. Forfeitures Participants vest in Company contributions in accordance with the provisions of their respective division and/or subsidiary plan as described in Note 3. Non-vested Company contributions are forfeited upon termination and are used to pay plan expenses and to reduce future Company contributions. Forfeitures available were approximately $1,226,000 and $914,000 at December 31, 2003 and 2002, respectively. Benefit Payments Benefit payments are recorded when paid. Plan Expenses The Company pays all administrative expenses of the Plan including trustee, record keeping, consulting, audit and legal fees, with the exception of loan administration fees, which are charged to participants. Taxes and investment fees related to the stock funds or mutual funds are paid from the net assets of such funds. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results will differ from these estimates. The most significant estimate relates to valuations of investments in the Master Trust. Risks and Uncertainties The Plan provides for investment options in various mutual funds and the L-3 Stock Fund. Investment securities are exposed to various risks, such as interest rate, market and credit risk. Due to the level of risk associated with certain investment securities and the level of uncertainty related to changes in the value of investment securities, it is at least reasonably possible that changes in risks in the near term would materially affect participants' account balances and the amounts reported in the statement of net assets available for benefits and the statement of changes in net assets available for benefits. 9 L-3 COMMUNICATIONS MASTER SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS- CONTINUED 3.

BENEFIT PAYMENTS Upon termination, participants may receive the vested portion of their account balance as soon as practicable after termination. Terminated participants who have an account balance in excess of $5,000 may elect to leave their account balance in the Plan and withdraw it at any time up to age 65. Assets in a participant's account may be withdrawn before termination of employment or before reaching age 59 1/2 only for financial hardship. Financial hardship is determined pursuant to provisions of the Plan and the IRC. Generally, a penalty will be imposed on withdrawals made before the participant reaches age 59 1/2. In the event of retirement or termination of employment prior to age 59 1/2, funds may be rolled over to another qualified plan or individual retirement account without being subject to income tax or a penalty. 6. LOANS The Plan provides for loans to active participants. Participants may not have more than one loan outstanding at any time. The maximum loan allowed to each participant is the lesser of (1) $50,000 less the highest outstanding loan balance over the prior 12 months or (2) 50% of the vested value of the participant's account in the Plan. The minimum loan amount is $1,000. The interest rate is based on the prime interest rate, as defined, plus one percent. Repayment periods generally range from one to five years, and six to thirty years for loans used in connection with the purchase of a principal residence. Loan repayments are made through payroll deductions, with principal and interest credited to the participants' fund accounts. Repayment of the entire balance is permitted at any time. Participant loans are secured by the participant's vested account balance. 7. TAX STATUS The Internal Revenue Service has determined and informed the Company by a letter dated August 5, 2002, that the Plan and related trust are designed in accordance with applicable sections of the IRC, and thus is exempt from federal income taxes. The Plan has been amended since receiving the determination letter. The Plan Administrator and the Plan's counsel believe that the Plan is designed and is currently being operated in compliance with the applicable regulations of the IRC. 8. RELATED-PARTY TRANSACTIONS Certain Plan investments are shares of mutual funds managed by FMTC and therefore these transactions qualify as party-in-interest. Fees paid by the Company for record keeping services were $38,271 for the year ended December 31, 2003. 14 L-3 COMMUNICATIONS MASTER SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS- CONTINUED 9. TERMINATION PRIORITIES Although the Company has not expressed intent to do so, the Company can discontinue its contributions and/or terminate any or all of the division and/or subsidiary plans at any time, subject to the provisions of ERISA. In the event of a discontinuance and/or termination of a division and/or subsidiary plan, participants in that plan will become 100 percent vested in Company contributions and the net assets of that plan will be allocated among the participants and their beneficiaries in accordance with the provisions of ERISA. 15 L-3 COMMUNICATIONS MASTER SAVINGS PLAN SCHEDULE G, PART III SCHEDULE OF NONEXEMPT TRANSACTIONS FOR THE YEAR ENDED DECEMBER 31, 2003 Identity Relationship Description Date Cost Current Value Net gain -------- ------------ ----------- ---- ---- ------------- -------- L-3 Communications Corporation Employer Indirect Loan 3/21/03 $ 23,102 $ 23,959 $ 857 L-3 Communications Corporation Employer Indirect Loan 5/30/03 27,617 29,646 2,029 L-3 Communications Corporation Employer Indirect Loan 12/15/03 1,746,465 1,748,786 2,321 16 Pursuant to the requirements of the Securities Exchange Act of 1934, the trustees of the L-3 Communications Master Savings Plan have duly caused this annual report to be signed on their behalf by the undersigned thereunto duly authorized.
