To the Advisory Committee
L-3 Ilex Systems Savings and Security Plan and Trust


We have audited the accompanying statements of net assets available for benefits
of L-3 Ilex Systems Savings and Security Plan and Trust (the Plan) as of
December 31, 2002 and 2001, and the related statements of changes in net assets
available for benefits for the years then ended. 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 years then ended 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 schedules are presented
for the purpose of additional analysis and are not a required part of the basic
financial statements but are supplemental information required by the Department
of Labor's Rules and Regulations for Reporting and Disclosure under the Employee
Retirement Income Security Act of 1974. These supplemental schedules are the
responsibility of the Plan's management. The supplemental schedules have been
subjected to the auditing procedures applied in the audits of the basic
financial statements and, in our opinion, are fairly stated in all material
respects in relation to the basic financial statements taken as a whole.

                           --------------------------


NOTE 1 - PLAN DESCRIPTION
-------------------------

               The following description of the L-3 Ilex Systems Savings and
Security Plan and Trust (the Plan) provides only general information. More
detailed information concerning the Plan may be found by consulting the Plan
document, which is available from the plan administrator.

               GENERAL
               -------
               The Plan is a defined contribution 401(k) profit sharing plan
with a salary deferral feature, covering all eligible employees of L-3
Communications Ilex Systems, Inc. (the Company and Plan Sponsor). The Plan is
subject to the provisions of the Employee Retirement Income Security Act of 1974
(ERISA).

               CONTRIBUTIONS
               -------------
               Participants may elect salary deferral contributions up to 15% of
their annual eligible compensation, not to exceed limitations established
annually by the Internal Revenue Service pursuant to IRC Section 402(g). Salary
deferral contributions and earnings thereon are not subject to taxation until
withdrawn from the Plan.

               The Plan provides for discretionary matching contributions. The
amount of the matching contribution is specified annually by the Company's Board
of Directors and shall be applied uniformly to all participants.

               PARTICIPANT ACCOUNTS
               --------------------
               Participant contributions are invested in various investment
funds based upon instructions by the participant.

               VESTING
               -------
               Participants are immediately vested in their voluntary
contributions plus actual earnings thereon. Company discretionary matching
contributions are vested in a graduated schedule as follows: 0 - 3 years, no
vesting; 3 or more years, 100% vested.

               PAYMENT OF BENEFITS
               -------------------
               Upon death, retirement or termination of employment, participants
are entitled to receive their vested account balance. If the balance is equal to
or less than $5,000, the balance will be distributed in a lump-sum cash payment.
If the account balance is over $5,000, the participant may elect to roll over
the balance to another qualified plan, receive the balance in a lump-sum cash
payment or receive annuity benefits as prescribed by the Plan.

NOTE 1 - PLAN DESCRIPTION (CONTINUED)
------------------------------------

               PAYMENT OF BENEFITS (Continued)
               ------------------------------
               The participant's share of Company contributions that have not
been vested will be forfeited. Forfeitures of Company matching contributions may
be used to reduce administrative expenses and reduce matching contributions for
the Plan year in which the forfeitures occur.

               LOANS
               -----
               Loans are available to all participants. The minimum loan is
$1,000 and the maximum loan available is the lesser of $50,000 or 50% of the
participant's vested account balance based on the value of the participant's
account as of the most recent valuation date. Loans are secured by the balance
in the participant's account and bear interest at rates ranging from 5.75% to
10.75%, which approximates the market rate at the inception of the loans.
Principal and interest are paid ratably through monthly payroll deductions.
Repayment periods cannot exceed five years unless the loan is used for the
purchase of a principal residence. In this instance, the repayment period may be
up to 15 years.


NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
---------------------------------------------------

               BASIS OF ACCOUNTING
               -------------------
               The financial statements of the Plan are prepared using the
accrual method of accounting.

               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.

               INVESTMENTS
               -----------
               Investments are recorded at fair value based upon quoted market
prices. The average cost method is used in determining the gain or loss arising
upon the sale of investments.

               Participant loans are valued at cost which approximates fair
value.

               Transactions are recorded on a trade date basis. Acquisition
costs are included in the cost of investments and sales are recorded net of
selling expenses.

               PLAN ASSETS HELD BY T. ROWE PRICE TRUST COMPANY, INVESTMENT
               MANAGER
               -----------------------------------------------------------
               The Plan's investment manager, T. Rowe Price Trust Company,
maintains plan assets. The accounts are credited with actual earnings on the
underlying investments and charged for plan withdrawals and management fees
charged by T. Rowe Price Trust Company. The Plan's investments and changes
therein have been reported by the investment manager as having been determined
through the use of current market values.

               PAYMENT OF BENEFITS
               -------------------
               Benefits are recorded when paid.

               TAX STATUS
               ----------
               The Plan received a favorable determination letter in October
1994, from the Internal Revenue Service stating that the Plan is qualified under
the provisions of Internal Revenue Code (IRC) Section 401(a) and the related
trust is exempt from federal income taxes under IRC Section 501(a). Accordingly,
no provision for income taxes is reflected in the accompanying financial
statements. The Plan Sponsor believes that the Plan is currently designed and
being operated in compliance with the applicable requirements of the Internal
Revenue Code. Continued qualification of the Plan depends on its future
operations.

               PLAN ADMINISTRATIVE EXPENSES
               ----------------------------
               Management fees are allocated on a pro rata basis to each
participant. The recordkeeper is paid by the Plan and all other significant
expenses are paid by the Plan Sponsor.
