                                 PROXY STATEMENT

         This proxy statement is furnished to the holders of the common stock,
par value $0.01 per share of L-3 Communications Holdings, Inc. in connection
with the solicitation of proxies for use at the 2002 Annual Meeting of
Stockholders to be held at the Rihga Royal Hotel, 151 West 54th Street, New
York, New York at 2:30 p.m., eastern daylight time, on Tuesday, April 23, 2002
(the "Annual Meeting").

                                   RECORD DATE

         The board of directors has fixed the close of business on March 15,
2002 as the record date for the Annual Meeting (the "Record Date"). Only
stockholders of record at the Record Date (the "Stockholders") are entitled to
notice of and to vote at the Annual Meeting or at any adjournments thereof, in
person or by proxy. At the Record Date, there were 39,608,831 shares of our
common stock outstanding. This proxy statement, the accompanying proxy card and
our Annual Report to stockholders are intended to be mailed on or about April 1,
2002 to each Stockholder entitled to vote at the Annual Meeting.

                                     PROXIES

         The proxy accompanying this proxy statement is solicited on behalf of
our board of directors for use at the Annual Meeting and any adjournments of the
Annual Meeting, and the expenses of solicitation of proxies will be borne by us.
The solicitation will be made primarily by mail, but our officers and regular
employees may also solicit proxies by telephone, telegraph, facsimile or in
person. We also have retained            to assist in soliciting proxies. Each
holder of common stock is entitled to one vote for each share of our common
stock held. The holders in person or by proxy of a majority of the common stock
entitled to be voted at the Annual Meeting shall constitute a quorum.

         Each Stockholder may appoint a person (who need not be a shareholder)
other than the persons named in the enclosed proxy to represent him or her at
the meeting by completing another proper proxy. In either case, such completed
proxy should be returned in the enclosed envelope provided for that purpose for
delivery before the meeting or should be delivered to our Secretary at 600 Third
Avenue, New York, New York 10016, not later than 5 p.m., eastern daylight time,
on Monday, April 22, 2002.

         Any proxy delivered pursuant to this solicitation is revocable at the
option of the person(s) executing the proxy upon our receipt, prior to the time
the proxy is voted, of a duly executed instrument revoking it, or of a duly
executed proxy bearing a later date, or in the case of death or incapacity of
the person(s) executing the proxy, of written notice of such death or
incapacity, or by such person(s) voting in person at the Annual Meeting. Unless
revoked, all proxies representing shares entitled to vote which are delivered
pursuant to this solicitation will be voted at the Annual Meeting and, where a
choice has been specified on the proxy card, will be voted in accordance with
such specification. WHERE A CHOICE HAS NOT BEEN SPECIFIED ON THE PROXY CARD, THE
PROXY WILL BE VOTED IN ACCORDANCE WITH THE RECOMMENDATIONS OF YOUR BOARD OF
DIRECTORS.

         Assuming a quorum is present, a majority of the shares of common stock
present in person or represented by proxy at the Annual Meeting is required for
the election of directors and for approval of all other items submitted to
Stockholders for their consideration. Abstentions and instances where brokers
are prohibited from exercising discretionary authority for beneficial owners who
have not returned a proxy (so-called "broker non-votes") will be counted for
purposes of determining a quorum, but will not be counted as either voting for
or against any proposal.

                                       1


                         VOTING BY TELEPHONE OR INTERNET

         Instead of submitting your vote by mail on the enclosed proxy card, you
can vote by telephone or over the Internet. The telephone and Internet voting
procedures, which comply with Delaware law, are designed to authenticate
Stockholders' identities, to allow Stockholders to vote their shares and to
confirm that their instructions have been properly recorded.

         Voting your proxy by mail, telephone or the Internet will not limit
your right to vote at the Annual Meeting if you later decide to attend in
person. If your shares are held in the name of a broker, bank or other record
holder, you must obtain a proxy from the record holder as to how to vote your
shares or obtain a proxy from the record holder to vote at the Annual Meeting.

         Stockholders with shares registered directly in their name in our stock
records maintained by our transfer agent, EquiServe Trust Company, N.A., may
vote their shares (1) by making a toll-free telephone call from the U.S. and
Canada to EquiServe at 1-877-PRX-VOTE (1-877-779-8683), (2) by submitting
their proxy over the Internet at the following address on the World Wide Web:
http://www.eproxyvote.com/lll, or (3) by mailing their signed proxy card.
Specific instructions to be followed by registered Stockholders are set forth on
the enclosed proxy card. Proxies submitted by telephone or over the Internet as
described above must be received by 5:00 p.m., eastern daylight time, on April
22, 2002.

REVOCATION OF PROXIES SUBMITTED BY TELEPHONE OR INTERNET

         To revoke a proxy previously submitted by telephone or over the
Internet, you may simply vote again at a later date, using the same procedures,
in which case your later submitted vote will be recorded and your earlier vote
revoked, or by attending the meeting and voting in person.

                        PROPOSAL 1. ELECTION OF DIRECTORS

         Our Amended and Restated Certificate of Incorporation and the Bylaws
provide for a board of directors whose number shall be fixed from time to time
exclusively pursuant to a resolution adopted by the board of directors. We have
eight directors. Our Amended and Restated Certificate of Incorporation provides
for a classified board of directors divided into three classes as follows: Frank
C. Lanza, Robert V. LaPenta, Robert B. Millard and John M. Shalikashvili
constitute a class with a term that expires at the upcoming annual meeting (the
"Class I Directors"); Thomas A. Corcoran, John E. Montague and Alan H.
Washkowitz constitute a class with a term that expires at the annual meeting in
2004 (the "Class II Directors"); and Arthur L. Simon constitutes a class with a
term that expires at the annual meeting in 2003 (the "Class III Director"). The
audit committee, acting as the nominating committee, has nominated, and the full
board of directors has ratified, the following slate of Class I nominees for a
three year term expiring in 2005: Mr. Lanza, Mr. LaPenta and Mr. Shalikashvili.
Action will be taken at the Annual Meeting for the election of these Class I
Director nominees. Mr. Millard has resigned from his position as a Class I
Director, effective at the upcoming annual meeting, and has been elected by the
board of directors to fill a vacancy as a Class III Director. Mr. Millard's term
as a Class III Director will expire at the annual meeting in 2003.

         It is intended that the proxies delivered pursuant to this solicitation
will be voted in favor of the election of Mr. Lanza, Mr. LaPenta and Mr.
Shalikashvili, except in cases of proxies bearing contrary instructions. In the
event that these nominees should become unavailable for election for any
presently unforeseen reason, the person named in the proxy will have the right
to use his discretion to vote for a substitute.

         The following information details offices held, other business
directorships, the classes and terms of the nominees and each director whose
term of office will continue after the 2002 Annual Meeting. Beneficial ownership
of equity securities of the nominees is shown under the caption "Security
Ownership of Management" on page 9.

           THE BOARD OF DIRECTORS AND CERTAIN COMMITTEES OF THE BOARD

         Our board of directors directs the management of our business and
affairs, as provided by Delaware law, and conducts its business through meetings
of the board of directors and two standing committees: the audit and


                                       5


compensation committees. In addition, from time to time, special committees may
be established under the direction of the board of directors when necessary to
address specific issues. We have no nominating committee; however, the audit
committee has agreed to perform the functions of the nominating committee. Each
executive officer serves at the discretion of the board of directors. During the
fiscal year ended December 31, 2001, the board of directors held four regularly
scheduled meetings and one special meeting. All of our directors attended at
least 75% of the combined number of board of directors meetings and committee
meetings during the past fiscal year.

         The audit committee currently consists of Messrs. Corcoran,
Shalikashvili (Chairman) and Simon. This committee, which met five times during
2001, is responsible generally for recommending to the board of directors the
independent accountants to be nominated to audit our financial statements;
approving the compensation of the independent accountants; meeting with our
independent accountants to review the proposed scope of the annual audit of our
financial statements; reviewing the findings of the independent accountants with
respect to the annual audit; and reviewing with management and the independent
accountants our periodic financial reports prior to our filing them with the
SEC and reporting annually to the board of directors with respect thereto. In
addition, the audit committee, acting as the nominating committee, nominated the
Class I members for reelection to the board of directors.

         The compensation committee consists of Messrs. Millard (Chairman),
Montague and Washkowitz. This committee, which met one time and acted by written
consent three times during 2001, is responsible for administering our 1997 Stock
Option Plan for Key Employees (the "1997 Plan") and our 1999 Long Term
Performances Plan (the "1999 Plan") and has limited authority to adopt
amendments to those plans. This committee is also responsible for recommending
to the board of directors the salaries to be paid to our Chief Executive Officer
and the President, and reviewing and approving the Chief Executive Officer's and
the President's other annual cash compensation and long-term incentives and the
total compensation to be paid to certain of our other executive officers.

COMPENSATION OF DIRECTORS

         The directors who are also our employees or employees of our
subsidiaries or affiliates do not receive compensation for their services as
directors. The non-affiliated directors receive annual compensation of $30,000
for service on the board of directors, of which $25,000 is paid in cash, and
$5,000 is paid in shares of our common stock. In addition, non-affiliated
directors receive an annual stock option grant of 1,500 shares of our common
stock, which will vest in three equal annual installments. The non-affiliated
directors are entitled to reimbursement for their reasonable out-of-pocket
expenses in connection with their travel to and attendance at meetings of the
board of directors or committees thereof. In addition, the non-affiliated
directors will be compensated $1,000 per meeting attended, including committee
meetings, up to a maximum of $2,000 per day.

         Non-affiliated directors may defer up to 100 percent of the cash
portion of their annual cash compensation (including meeting fees) otherwise
payable to the director. Subject to certain limitations, a participating
director's deferred compensation will be distributed in a lump sum on, or
distribution in annual installments commencing on, the 30th day following the
date he or she ceases to be a director. Deferral elections are irrevocable
during any calendar year and must be made before the beginning the calendar year
in which his/her compensation is earned. Interest is accrued on deferred
amounts. Depending on a director's investment election, deferred amounts earn
interest at a rate based on the 90-day U.S. Government Treasury Bill or the
performance of our common stock.

     more than one person (if, for example, persons share the power to vote or

     beneficially owned by a person if the person has the right to acquire the
     shares (for example, upon exercise of an option) within 60 days of the date

     ownership of any person, the amount of shares outstanding is deemed to
     include the amount of shares beneficially owned by such person (and only
     such person) by reason of these acquisition rights. As a result, the

(1)      In accordance with SEC rules, the values of the in-the-money options
         were calculated by subtracting the exercise prices of the options from
         the December 31, 2001 closing stock price of our common stock of
         $90.00.

(2)      These options are unexercisable because they have not yet vested under
         their terms.

                          REPORT OF THE AUDIT COMMITTEE

         The directors who serve on the audit committee are all "independent" in
accordance with the New York Stock Exchange listing standards.

         We have reviewed and discussed with management the Company's audited
financial statements as of and for the year ended December 31, 2001.

                                       11


         We have discussed with the independent auditors, PricewaterhouseCoopers
LLP, the matters required to be discussed by Statement on Auditing Standards No.
61, Communication with Audit Committees, as amended, by the Auditing Standards
Board of the American Institute of Certified Public Accountants.

         We have received and reviewed the written disclosures and the letter
from PricewaterhouseCoopers LLP, required by Independence Standard No. 1,
Independence Discussions with Audit Committees, as amended, by the Independence
Standards Board, and have discussed with the auditors their independence.

         Based on the activities referred to above, we recommended to the board
of directors that the financial statements referred to above be included in our
Annual Report on Form 10-K for the year ended December 31, 2001.

                            INDEPENDENT AUDITOR FEES

         For services rendered in 2001 by PricewaterhouseCoopers LLP, our
independent auditors, we incurred the following fees:

     o    Audit Fees (for the audit of the 2001 financial statements and
          quarterly reviews) -- $1,087,000

     o    Financial Information Systems Design and Implementation Fees --$0

     o    All Other Fees ($1,510,036 for tax services and $1,155,343 for other
          audit services, including acquisition audits, review of SEC
          registrations, benefit plan and other statutory audits, and $200,000
          applicable to the audit of our 2000 financial statements) --
          $2,665,379

         As set forth in the Audit Committee Charter, the audit committee has
considered and determined that the provision of the services covered under the
caption All Other Fees is compatible with maintaining the auditor's
independence.

             COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

         The compensation committee is responsible for reviewing the design of,
and pay levels generated by, our compensation and benefit programs for our
executive officers. The committee is also responsible for administering our
stock option program.

         The committee is committed to ensuring an executive compensation
program that supports our mission -- to maximize stockholder value. Thus, the
executive compensation is structured around the following tenets:

     o    Total compensation programs should strengthen the relationship between
          pay and performance by emphasizing variable, at-risk compensation that
          is dependent on our achievement and individual performance goals.

     o    Management should be focused on the long-term interests of
          stockholders. Thus, a significant portion of the compensation
          opportunity should be long-term, at-risk pay in the form of stock
          options.

     o    We must maintain our ability to attract, retain, and encourage the
          development of qualified, capable executives. Total compensation
          opportunities will mirror those offered by comparably sized
          organizations within the aerospace and defense industries -- for those
          positions where the labor market is not limited to these industries,
          we will reference broader general industry information for similarly
          sized organizations.

         The comparative group used for compensation purposes will generally be
broader than the group that comprises the published industry index in the
performance graph included in this proxy statement. The compensation committee
believes that our competition for executive talent is not limited to the
companies included in the published industry index established for comparing
stockholder returns.

                                       12


         The key elements of our executive compensation program are base salary,
annual incentives, and long-term compensation. These key elements are addressed
separately below.

BASE SALARIES

         The compensation committee will regularly review the base salary for
the Chief Executive Officer and the President. We have established internal
relationships of other senior executive positions to those of the Chief
Executive Officer and the President, and base salaries for these other positions
flow from those relationships. Base salaries will be targeted at the median of
market levels with adjustments above or below market to recognize varying levels
of responsibility, prior experience, breadth of knowledge, as well as external
pay practices.

         Increases to base salaries will be driven primarily by individual
performance. Individual performance will be evaluated based on sustained levels
of individual contribution.

         As reflected in the Summary Compensation Table, Mr. Lanza's base salary
was $750,000 in 2001, 2000 and 1999 as provided for in his employment agreement.
In determining future increases to Mr. Lanza's base salary, the compensation
committee will consider his individual performance as measured by short-term
achievements as well as his contributions to long-term organizational success.
The compensation committee will also compare Mr. Lanza's base salary to base
salaries of chief executive officers among comparable companies.

ANNUAL INCENTIVES

         The annual incentive plan is structured to provide a variable pay
opportunity based on performance. Actual bonuses are based on an assessment of
the participant's contributions toward organizational success.

         Mr. Lanza received a bonus of $750,000 in 2001.

         On April 30, 1997 at the time Messrs. Lanza and LaPenta entered into
their respective employment agreements they were each granted a stock option on
1,142,857 shares of common stock, 50% of which vested over time and 50% of which
the vesting date was determined based on our achievement of certain annual or
cumulative performance targets. On April 5, 1999, in recognition of their
superior performance, the compensation committee amended the option grants to
Messrs. Lanza and LaPenta to eliminate the performance targets and to provide
that the unvested portion of the performance options vest and become exercisable
as of April 30, 2000. In determining to amend the option grants, the
compensation committee also took into account the fact that the existing
performance targets were no longer applicable as a result of the acquisitions
completed by us in 1998 and of our ongoing acquisition activities. See
"Employment Agreements."

LONG-TERM INCENTIVES

         Long-term incentives are provided pursuant to the 1997 Plan and the
1999 Plan.

         Stock options will be granted at a price not less than the fair market
value of our common stock on the date of grant. The ultimate value of an option
grant to the recipient depends on the stockholder value created between the date
of grant and the date of exercise. Option award size is based primarily on
competitive practice but may also be adjusted to reflect factors such as
individual and our company's performance.

POLICY WITH RESPECT TO THE $1 MILLION DEDUCTION LIMIT

         Section 162(m) of the Internal Revenue Code generally limits the
corporate deduction for compensation paid to the named executive officers to $1
million, unless certain requirements are met. The compensation committee will
consider the impact of this provision when making compensation decisions.
However, the compensation committee will weigh all pertinent factors to
determine appropriate plan design and incentive awards.

         Members of the compensation committee are Robert B. Millard (Chairman),
John E. Montague and Alan H. Washkowitz.

                             STOCK PERFORMANCE GRAPH

         The graph below compares the cumulative total return of our common
stock with the cumulative total return of the Standard & Poor's 500 Composite
Stock Index and a peer group index, for the period from May 19, 1998 to December
31, 2001. These figures assume that all dividends paid over the performance
period were reinvested, and that the starting value of each index and the
investment in our common stock was $100 on May 19, 1998. The starting point for
the measurement of our common stock cumulative total return was our initial
public offering price of $22.00 per share. The peer group index is composed of
Alliant Techsystems Inc., General Dynamics Corporation and Northrop Grumman
Corporation. The graph is not, and is not intended to be, indicative of future
performance of our common stock.

           COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

         During the 2001 fiscal year, Messrs. Robert Millard, John Montague and
Alan Washkowitz served as members of the compensation committee of the board of
directors. None of these individuals has served us or any of our subsidiaries as
an officer or employee. Messrs. Millard and Washkowitz are limited partners of
Lehman Brothers Capital Partners III, L.P., which, together with Lehman Brothers
Holdings, Inc. and certain of their affiliates, owned 15.9 % of our outstanding
common stock as of March 12, 2001 and, as of March 15, 2002 owned less than
five percent of our outstanding common stock.

         Pursuant to a Stockholders Agreement entered into in connection with
our incorporation, Lehman Brothers Capital Partners III, L.P. and its affiliates
that directly own our common stock (the "Lehman Partnership"), have the right
from time to time subject to certain conditions, to require us to register under
the Securities Act shares of our common stock that the Lehman Partnership holds.
The Lehman Partnership has the right to request up to four demand registrations
and also has piggyback registration rights. We have agreed in the Stockholders
Agreement to pay expenses in connection with, among other things, (i) up to
three demand registrations requested by the Lehman Partnership and (ii) any
registration in which the existing stockholders participate through piggyback
registration rights granted under such agreement.

         None of our executive officers serves as a member of the board of
directors or compensation committee of any entity which has one or more
executive officers serving as a member of our board of directors or compensation
committee.


                                       15




                             EMPLOYMENT AGREEMENTS



         We have entered into an employment agreement (the "Employment
Agreements") effective on April 30, 1997 with each of Mr. Lanza, our Chairman
and Chief Executive Officer, who will receive a base salary of $750,000 per
annum and appropriate executive level benefits, and Mr. LaPenta, our President
and Chief Financial Officer, who will receive a base salary of $500,000 per
annum and appropriate executive level benefits. The Employment Agreements
provide for an initial term of five years, which will automatically renew for
one-year periods thereafter, unless a party thereto gives notice of its intent
to terminate at least 90 days prior to the expiration of the term. We are
currently negotiating the terms of a renewal of these contracts.

         Upon a termination without cause or resignation for good reason, we
will be obligated, through the end of the term, to (i) continue to pay the base
salary and (ii) continue to provide life insurance and medical and
hospitalization benefits comparable to those provided to other senior
executives; provided, however, that any such coverage shall terminate to the
extent that Mr. Lanza or Mr. LaPenta, as the case may be, is offered or obtains
comparable benefits coverage from any other employer. The Employment Agreements
provide for confidentiality during employment and at all times thereafter. There
is also a noncompetition and non-solicitation covenant which is effective during
the employment term and for one year thereafter; provided, however, that if the
employment terminates following the expiration of the initial term, the
noncompetition covenant will only be effective during the period, if any, that
we pay the severance described above.

         We have granted each of Messrs. Lanza and LaPenta nonqualified options
to purchase, at $6.47 per share, 1,142,857 shares of our common stock. In each
case, half of the options were structured as "time options" and half were
structured initially as "performance options," collectively referred to herein
as the options. The time options became exercisable with respect to 20% of the
shares subject to the time options on each of March 2, 1998, April 30, 1999 and
April 30, 2000 and will become exercisable with respect to an additional 20% of
the shares subject to the time options on each of April 30, 2001 and 2002 if
employment continues through and including these dates. The performance options
were initially structured to become exercisable nine years after the grant date,
but became exercisable earlier if certain targets for our earnings before
interest, income taxes, depreciation and amortization were achieved. On April 5,
1999, we amended the performance options to eliminate the performance target
acceleration provisions and to provide that the unvested portion of the
performance options vest and become exercisable as of April 30, 2000. The option
term is ten years through April 30, 2007; except that if (i) the option-holder
is fired for cause or resigns without good reason, the options will expire upon
termination of employment or (ii) the option-holder is fired without cause,
resigns for good reason, dies, becomes disabled or retires, the options will
expire one year after termination of employment. Unexercisable options will
terminate upon termination of employment, unless acceleration is expressly
provided for. Upon a change of control, we may terminate the options, so long as
the option-holders are cashed out or permitted to exercise their options prior
to this change of control.

         We also have entered into a split-dollar life insurance agreement with
Mr. LaPenta. Under the split-dollar agreement, we own and pay the premiums on
the life insurance policy, and Mr. LaPenta has the right to designate a
beneficiary to receive a fixed portion of the policy death benefit. The balance
of the death benefit will be payable to us as a recovery of our investment.

         As of December 31, 2001, the current annual compensation and current
years of credited service (including for Messrs. LaPenta and Strianese, years of
credited service as an employee of Loral and Lockheed Martin) for each of the
following persons were: Mr. Lanza, $1,250,000 and five years; Mr. LaPenta,
$945,577 and 30 years; Mr. Strianese, $480,000 and 12 years; Mr. Cambria,
$460,000 and five years; and Mr. Schafer, $423,320 and three years.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

         As of March 15, 2002 the Lehman Partnership owned 4.4% of our common
stock; and prior to their sale of our common stock pursuant to Rule 144A on
September 17, 2001, the Lehman Partnership beneficially owned more than five
percent of our common stock.

STOCKHOLDERS AGREEMENT

         In connection with our incorporation we, Lehman Brothers Capital
Partners III, L.P. and certain of its affiliates, Messrs. Lanza and LaPenta and
Lockheed Martin entered into the Stockholders Agreement, which terminated upon
the completion of our initial public offering and upon the sale of our common
stock to less than 10% of our outstanding common stock, except for the terms
relating to:

          o    registration rights; and

          o    the standstill agreement by Lockheed Martin.

         Pursuant to the Stockholders Agreement, at this time Messrs. Lanza and
LaPenta and the Lehman Partnership have the right, subject to certain
conditions, to require L-3 Communications Holdings to register their shares of
our common stock under the Securities Act of 1933. The Lehman Partnership has
four demand rights and each of Messrs. Lanza and LaPenta has one demand
registration right. Lockheed Martin sold all of its shares of our common stock
in 1999. In addition, the Stockholders Agreement also provides some existing
stockholders with piggyback registration rights. The Stockholders Agreement
provides, among other things, that we will pay expenses incurred in connection
with:

          o    up to three demand registrations requested by the Lehman
               Partnership and the two demand registrations requested by each of
               Messrs. Lanza and LaPenta; and

          o    any registration in which those parties participate through
               piggyback registration rights granted under the agreement.

         The Lehman Partnership sold 2.0 million of their shares of our common
stock through the exercise of their piggyback registration rights in our
February 1999 common stock offering.

         Under the Stockholders Agreement, Lockheed Martin is subject to a
standstill arrangement that expires on April 30, 2002, which generally prohibits
its share ownership percentage in us, if any, from exceeding 34.9%.

                                       17


TRANSACTIONS WITH AFFILIATES

     One provision of the Stockholders Agreement which expired after the Lehman
Partnership no longer owned 10% of our common stock, gave Lehman Brothers Inc.
the exclusive right to provide investment banking services to us, other than in
connection with cash acquisitions undertaken by us, through April 2002.

     Over the past three years, Lehman Brothers Inc. has entered into various
transactions with us and our subsidiaries. As required by the Stockholders
Agreement, all fees paid in connection with such transactions and services were
mutually agreed upon and, in our opinion, based on similar transactions and
practices in the investment banking industry. We believe that all of these
transactions were entered into on terms and conditions at least as favorable to
us as they would have been had we entered into these transactions with other
investment banks.

CAPITAL MARKETS SERVICES

     In May 1998, Lehman Brothers Inc. acted as one of several initial
purchasers and placement agents of $180.0 million of 8-1/2% Senior Subordinated
Notes due 2008 issued by our subsidiary, L-3 Communications. In May 1998, Lehman
Brothers Inc. acted as lead underwriter of our common stock we sold in our
initial public offering. Lehman Brothers Inc. also acted as one of several
initial purchasers and placement agents of $200.0 million of 8% Senior
Subordinated Notes due 2008 issued by L-3 Communications in December 1998. In
February 1999, Lehman Brothers Inc. acted as lead underwriter of the 5.0 million
shares we sold in a follow-on public offering. Additionally, as part of that
transaction, the Lehman Partnership sold 6.5 million shares of their shares of
our common stock in a secondary public offering. In November and December 2000,
Lehman Brothers Inc. was the sole initial purchaser of $300.0 million of our
5.25% Convertible Senior Subordinated Notes due 2009. In October 2001, Lehman
Brothers Inc. acted as one of several initial purchasers of $420.0 million of
our 4% Senior Subordinated Convertible Contingent Debt Securities due 2011. In
each of these financing transactions, Lehman Brothers Inc. received customary
fees, underwriting discounts and commissions.

     In addition, Lehman Brothers Inc. has been engaged as joint book running
manager and/or joint book running initial purchaser of a contemplated offering
of debt securities to replace our bridge loan facility entered into in March
2002 in connection with the Raytheon Acquisition, as defined below.

MERGER AND ACQUISITIONS ADVISORY SERVICES

     In January 1999, Lehman Brothers Inc. acted as our advisor in connection
with our acquisition of Microdyne Corporation. In April 1999, Lehman Brothers
Inc. acted as our advisor in connection with our acquisition of Aydin
Corporation. In 2002, Lehman Brothers Inc., acted as our advisor in connection
with the acquisition of all of the assets of Aircraft Integration Systems, a
division of Raytheon Company (the "Raytheon Acquisition"). For these services,
Lehman Brothers Inc. received customary fees.

SENIOR CREDIT FACILITIES

     In May 1998, Lehman Brothers Inc. acted as joint lead arranger and joint
book manager and Lehman Commercial Paper Inc., an affiliate of Lehman Brothers
Inc., acted as documentation agent, syndicate agent and lender in connection
with two of L-3 Communications' senior credit facilities. In connection with
those transactions both Lehman Brothers Inc. and Lehman Commercial Paper Inc.
received customary fees and interest. In connection with L-3 Communications'
$300.0 million 364-day revolving senior credit facility entered into in April
2000, Lehman Brothers Inc. acted as joint lead arranger and joint book manager
and Lehman Commercial Paper Inc. acted as documentation agent, syndicate agent
and lender. L-3 Communications entered into its senior credit facilities after
arms-length negotiations and on the same terms with all of the other parties
thereunder. During the twelve-month period ended February 28, 2002 Lehman
Brothers Inc. and Lehman Commercial Paper Inc. received interest payments and
fees under these senior credit facilities totaling approximately $      million.


         In connection with the Raytheon Acquisition, Lehman Brothers Inc. acted
as joint book running manager and joint lead arranger and Lehman Commercial
Paper Inc. acted as administrative agent with respect to our bridge loan
facility entered into in March 2002. In connection with those transactions both
Lehman Brothers Inc. and Lehman Commercial Paper Inc. received customary fees
and interest.

             SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

         Section 16(a) of the Securities Exchange Act of 1934 requires our
officers and directors, and persons who own more than 10% of a registered class
of our equity securities, to file reports of ownership and changes in ownership
with the SEC and the NYSE. Officers, directors and greater than 10% shareholders
are required by SEC regulation to furnish us with copies of all Section 16(a)
forms they file. All Section 16(a) forms required to be filed were filed on a
timely basis.


                                       18


        PROPOSAL 2. INCREASING THE AUTHORIZED COMMON AND PREFERRED STOCK

         On February 5, 2002, subject to stockholder approval, the Board of
Directors authorized an amendment to our Amended and Restated Certificate of
Incorporation to increase the number of authorized shares of Common Stock from
one hundred million (100,000,000) shares to three hundred million (300,000,000)
shares and the number of authorized shares of our preferred stock ("Preferred
Stock"), from twenty-five million (25,000,000) to fifty million (50,000,000)
shares. If approved by the stockholders, the first paragraph of Section 4 of our
Amended and Restated Certificate of Incorporation would be amended to provide as
follows:

                           "Fourth: The total number of shares of all classes of
                  stock which the Corporation shall have the authority to issue
                  is 350,000,000 shares, consisting of 300,000,000 shares of
                  Common Stock, par value $.01 per share (the "Common Stock")
                  and 50,000,000 share of preferred stock, par value $0.01 per
                  share (the "Preferred Stock"). Set forth below with respect to
                  each class of stock of the Corporation is a statement of the
                  voting powers and the designations, preferences, rights,
                  qualifications, limitations and restrictions thereof:"

         We are currently authorized to issue 100,000,000 shares of Common
Stock. As of the Record Date, 39,608,831 shares of Common Stock were issued and
outstanding, and 15,392,774 shares of Common stock were reserved for the (1)
potential conversion of our convertible notes and convertible contingent debt
securities into shares of Common Stock, (2) issuance upon exercise of
outstanding stock options, (3) options that may be granted in the future under
our stock option plan, and (4) the issuance of Common Stock pursuant to our
employee stock purchase plan. Accordingly, there are only 44,998,395 shares of
Common Stock available for issuance. The Company is currently authorized to
issue 25,000,000 shares of Preferred Stock. As of the Record Date, no shares of
preferred stock were issued and outstanding.

         The Board of Directors believes that it is advisable and in our best
interest and in the best interest of our stockholders to have available
authorized but unissued shares of Common Stock and Preferred Stock in an amount
adequate to provide for our future financing needs. The additional shares will
be available for issuance from time to time in the discretion of the Board of
Directors, normally without further stockholder action (except as may be
required for a particular transaction by applicable law, requirements of
regulatory agencies or by New York Stock Exchange rules), for any proper
corporate purpose including, among other things, stock splits, stock dividends,
future acquisitions of property or securities of other corporations, convertible
debt financing and equity financings. As previously announced, we intend to
finance part of the Raytheon Acquisition with the sale of our Common Stock,
which if such sale is successfully completed, will use a portion of our
authorized but unissued shares of Common Stock. As we are not contemplating
offerings of the Preferred Stock in the proximate future, the terms of such
securities have not been determined. The rights and preferences of Preferred
Stock, such as dividends or interest rates, conversion prices, voting rights,
liquidation preferences, redemption prices, maturity dates and similar matters,
will be determined by the Board of Directors, without further authorization of
the stockholders. No stockholder has any preemptive rights regarding future
issuance of any shares of Common Stock and Preferred Stock.

         We have no present plans, understandings or agreements for the issuance
or use of the proposed additional shares of Common Stock and Preferred Stock.
Further, the Board of Directors believes that if an increase in the authorized
number of shares of Common Stock and Preferred Stock were to be postponed until
a specific need arose, the delay and expense incident to obtaining the approval
of the Company's stockholders at that time could significantly impair the
Company's ability to meet financing requirements or other objectives.

         The issuance of additional shares of Common Stock and Preferred Stock
may have the effect of diluting the stock ownership of persons seeking to obtain
control of us. Although the Board of Directors has no present intention of doing
so, our authorized but unissued Common Stock and Preferred Stock could be issued
in one or more transactions that would make a takeover of the Company more
difficult or costly, and less likely. The proposed amendment to the Amended and
Restated Certificate of Incorporation is not being recommended in response to
any specific effort of which we are aware to obtain control of the Company, nor
is the Board of Directors currently proposing to stockholders any anti-takeover
measures.

                                       19


         A majority of the outstanding voting stock is required to amend our
Amended and Restated Certificate of Incorporation.

         THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE APPROVAL OF THE
AMENDMENT TO OUR AMENDED AND RESTATED CERTIFICATE OF INCORPORATION TO INCREASE
THE AMOUNT OF OUR AUTHORIZED COMMON AND PREFERRED STOCK.

                  PROPOSAL 3. SELECTION OF INDEPENDENT AUDITORS

         The board of directors has selected PricewaterhouseCoopers LLP to act
as our independent auditors for the 2002 fiscal year, and a proposal to ratify
this selection will be submitted to the Annual Meeting. PricewaterhouseCoopers
LLP has acted as our independent auditors since our formation in 1997 and
management believes it desirable and in our best interests to continue the
employment of that firm. Representatives of PricewaterhouseCoopers LLP will be
present at the Annual Meeting. Such representatives will have the opportunity to
make a statement if they desire to do so, and are expected to be available to
respond to appropriate questions.

         If the foregoing proposal is not approved by the holders of a majority
of the shares represented at the Annual Meeting and voting on the proposal, the
selection of independent auditors will be reconsidered by the board of
directors.

         THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR RATIFICATION OF THE
APPOINTMENT OF PRICEWATERHOUSECOOPERS LLP AS INDEPENDENT AUDITORS.

                 INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE
