                         REPORT OF INDEPENDENT AUDITORS


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 as of December 31, 2002 and 2001,
and the related statement of changes in net assets available for benefits for
the year ended December 31, 2002. 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 auditing standards generally accepted
in the United States of America. 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, 2002 and 2001, and the changes in net assets available for benefits
for the year ended December 31, 2002 in conformity with accounting principles
generally accepted in the United States of America.

Our audits were performed 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.

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 41 locations of the Company 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 to $11,000 for participants under 50
years of age and $12,000 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. Participants have the option of investing
participant-directed employee and employer contributions in the L-3 Stock Fund,
as well as other investment options that are described below.

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.

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 depreciation in the fair value of the Plan's investments, 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 net unrealized
depreciation on those investments. The net depreciation 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 $914,000 and $630,000 at December 31, 2002 and
2001, respectively.


Benefit Payments

Benefit payments are recorded when paid.

Plan Expenses

The Company pays all administrative expenses of the Plan including trust, 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 stock
funds. 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.

5. 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 $39,463 for the year ended December 31,
2002.

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.
