                         REPORT OF INDEPENDENT AUDITORS


To the Participants and Administrator of
the Aviation Communications & Surveillance Systems 401(K) Plan:


We have audited the accompanying statements of net assets available for benefits
of the Aviation Communications & Surveillance Systems 401(K) 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.

           AVIATION COMMUNICATIONS & SURVEILLANCE SYSTEMS 401(K) PLAN
                          NOTES TO FINANCIAL STATEMENTS

1. PLAN DESCRIPTION

General
-------

The Aviation Communications & Surveillance Systems 401(k) Plan (the "Plan") was
established effective June 1, 2001. Aviation Communications & Surveillance
Systems, LLC (the "Company") maintains the Plan for its eligible employees.
Employees of the Company who were participants in the L-3 Communications Master
Savings Plan (the "Prior Plan") became participants in the Plan on June 1, 2001.
The following description of the Plan provides only general information.
Complete descriptions of the Plan, including eligibility requirements and
vesting provisions, are contained in the Plan documents.

The Plan is a defined contribution 401(k) plan and is administered by the
Benefit Plan Committee ("Plan Administrator") appointed by the Company. The Plan
is designed to provide eligible employees with tax advantaged long-term savings
for retirement. The Plan 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
-------------

Full time employees are eligible to participate in the Plan as of their date of
hire. Part time employees must complete at least 1,000 hours of service, from
the date of hire, before being eligible to participate in the Plan. 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 of 1986, as
amended, limited the maximum amount an employee may contribute on a pre-tax
basis in 2002 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.

The Company matches 50% of participants' contributions up to a maximum
participant elected contribution percentage of 8% of compensation, which
increases to 100% of participants' contributions, up to 8% of compensation after
5 years of service. Company contributions are made in shares of L-3
Communications Holdings, Inc. common stock. Contributions are subject to
Internal Revenue Code ("IRC") limitations.

Vesting
-------

On June 1, 2001, participants of the Plan who were participants in the Prior
Plan on May 31, 2001 became fully vested in Company contributions and earnings
thereof in the Prior Plan. Participants will become fully vested in Company
contributions of the Plan upon 1) disability, 2) death or 3) the participants
65th birthday if the participant is actively employed by the Company. The
following table presents the vesting schedule for Plan participants.

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.

Participant account balances from the Prior Plan may not be transferred into the

2. 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 L-3 Communications Master Savings Plan, the L-3 Communications
Systems- East Savings Plan, the Coleman Research Corporation Money Purchase Plan
and the SPD Technologies Defined Contribution Retirement Plan, collectively
referred to as the Participating Plans. During the year ended December 31, 2002,
the L-3 Communications Systems- East Savings Plan and the Coleman Research
Corporation Money Purchase Plan were merged into the L-3 Communications Master
Savings 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 described
in Note 1 maintained by FMTC. 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 shares 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
business 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.

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
-----------

Non-vested Company contributions are forfeited upon termination and used to pay
plan expenses and to reduce future Company contributions. Forfeitures available
were approximately $5,000 at December 31, 2002.

                    NOTES TO FINANCIAL STATEMENTS- CONTINUED


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 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.

4. BENEFIT PAYMENTS

Upon termination, participants may receive the vested portion of their account
balance as soon as practicable after termination, at the participants option,
either in a lump sum or in periodic installments as provided for in the Plan
document. 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.


5. 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.
The maximum term of a loan is 5 years or 30 years if used to purchase 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. Participants who terminate employment may continue to
repay their outstanding loans as permitted by the Plan document. Participant
loans are secured by the participant's vested account balance.


6. TAX STATUS

The Internal Revenue Service has determined and informed the Company by a letter
dated May 6, 2003, 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 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.


7. 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 $2,250 for the year ended December 31,
2002.

8. TERMINATION PRIORITIES

Although the Company has not expressed intent to do so, the Company can
discontinue its contributions and/or terminate the Plan at any time, subject to
the provisions of ERISA. In the event of a discontinuance and/or termination of
the Plan, participants in that plan will become 100 percent vested in Company
contributions and the net assets of the Plan will be allocated among the
participants and their beneficiaries in accordance with the provisions of ERISA.
