                       REPORT OF INDEPENDENT ACCOUNTANTS




To the Board of Directors of Raytheon Company:


In our opinion, the accompanying combined balance sheets and the related
combined statements of operations and comprehensive income, parent company
investment and cash flows present fairly, in all material respects, the
financial position of the Aircraft Integration Systems Business (the "Company")
of Raytheon Company at December 31, 2001 and 2000, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 2001 in conformity with accounting principles generally accepted
in the United States of America. These financial statements are the
responsibility of the Company'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 auditing standards generally
accepted in the United States of America, which 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, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.


The Company is a member of a group of affiliated companies and, as disclosed in
the financial statements, has extensive transactions and relationships with
members of the group. Because of these relationships, it is possible that the
terms of these transactions are not the same as those that would result from
transactions among wholly unrelated parties.

                     AIRCRAFT INTEGRATION SYSTEMS BUSINESS
                     NOTES TO COMBINED FINANCIAL STATEMENTS


1. BACKGROUND AND BASIS OF PRESENTATION

The Aircraft Integration Systems Business (the "Company") of Raytheon Company
and its subsidiaries (the "Parent") is engaged in the development and
integration of complex electronic systems for airborne intelligence,
surveillance, and reconnaissance missions. The combined financial statements
presented may not be indicative of the financial position or results of
operations that would have been achieved had the Company operated as a
nonaffiliated entity.


2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES


PRINCIPLES OF COMBINATION

The combined financial statements include the accounts of certain similar
business operations that have historically been presented as a portion of
Aircraft Integration Systems (AIS), a reportable segment of the Parent. The
portion of AIS that has not been included consists primarily of a majority of
the ASTOR program and the Boeing Business Jet programs. All material
intercompany transactions have been eliminated.


REVENUE RECOGNITION

Sales under long-term contracts are recorded under the percentage of completion
method. Costs and estimated gross margins are recorded as sales as work is
performed based on the percentage that incurred costs bear to estimated total
costs utilizing the most recent estimates of costs and funding. Amounts
representing contract change orders, claims or other items are included in
sales only when they can be reasonably estimated and realization is probable.
Some contracts contain incentive provisions based upon performance in relation
to established targets which are recognized in the contract estimates when
deemed realizable. Since many contracts extend over a long period of time,
revisions in cost and funding estimates during the progress of work have the
effect of adjusting earnings applicable to performance in prior periods in the
current period. When the current contract estimate indicates a loss, provision
is made for the total anticipated loss in the current period.


RESEARCH AND DEVELOPMENT EXPENSES

Expenditures for company-sponsored research and development projects are
expensed as incurred. Customer-sponsored research and development projects
performed under contracts are accounted for as contract costs as the work is
performed.


FEDERAL INCOME TAXES

Historically, the Company's operations have been included in the consolidated
income tax returns filed by the Parent. Federal income tax expense in the
statement of operations is calculated on a separate tax return basis as if the
Company had operated as a stand-alone entity. The provision for income taxes is
calculated in accordance with Statement of Financial Accounting Standards No.
109, Accounting for Income Taxes, which requires the recognition of deferred
income taxes using the liability method.


CASH AND CASH EQUIVALENTS

Cash and cash equivalents consist of cash and short-term, highly liquid
investments with original maturities of 90 days or less.


CONTRACTS IN PROCESS

Contracts in process are stated at cost plus estimated profit but not in excess
of realizable value.

                                      A-6


                     AIRCRAFT INTEGRATION SYSTEMS BUSINESS
             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)

INVENTORIES

Inventories consist of consumables and parts used in the performance of
contracts and are valued at the lower of cost or market, cost being determined
on a weighted-average basis. A reserve is established for inventory items
considered excess or obsolete.


PROPERTY, PLANT, AND EQUIPMENT

Property, plant, and equipment are stated at cost. Major improvements are
capitalized while expenditures for maintenance, repairs, and minor improvements
are charged to expense. When assets are retired or otherwise disposed of, the
assets and related accumulated depreciation and amortization are eliminated
from the accounts and any resulting gain or loss is reflected in income.

Provisions for depreciation are computed on a combination of accelerated and
straight-line methods. Depreciation provisions are based on estimated useful
lives as follows: buildings -- 20 to 45 years and machinery and equipment -- 3
to 10 years. Leasehold improvements are amortized over the lesser of the
remaining life of the lease or the estimated useful life of the improvement.


GOODWILL

Goodwill, which represents the excess of the acquisition cost over the fair
value of the net assets recorded, relates to the allocation of a portion of the
goodwill associated with the Parent's acquisition of E-Systems, Inc. in 1995
and Chrysler Technologies, Inc. in 1996. Goodwill is amortized using the
straight-line method over its estimated useful life of 40 years.


COMPUTER SOFTWARE

Internal use computer software is stated at cost less accumulated amortization
and is amortized using the straight-line method over its estimated useful life
ranging from 4 to 10 years.


IMPAIRMENT OF LONG-LIVED ASSETS

Upon indication of possible impairment, the Company evaluates the
recoverability of long-lived assets by measuring the carrying amount of the
assets against the related undiscounted future cash flows. When an evaluation
indicates that the future undiscounted cash flows are not sufficient to recover
the carrying value of the asset, the asset is adjusted to its estimated fair
value.


ADVANCE PAYMENTS

Advance payments represent funds received in excess of work performed on
contracts in process.


ACCOUNTS PAYABLE

Accounts payable includes a book overdraft of $3.1 million at December 31, 2001
and $5.9 million at December 31, 2000.


FOREIGN CURRENCY

Foreign exchange transaction gains and losses in 2001, 2000, and 1999 were not
material.


COMPREHENSIVE INCOME

Comprehensive income and its components are presented in the statement of
operations and other comprehensive income. The minimum pension liability
adjustment is shown net of tax benefits of $3.1 million in 2001.


                                      A-7


                     AIRCRAFT INTEGRATION SYSTEMS BUSINESS
             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)

PENSION AND POSTRETIREMENT COSTS

The Parent has several pension and retirement plans covering the majority of
the Company's employees. In addition, the Company maintains a separate plan for
certain employees (see Note 12). Annual charges to income are made for the cost
of the plans, including current service costs, interest on projected benefit
obligations, and net amortization and deferrals, increased or reduced by the
return on assets. Unfunded accumulated benefit obligations for the Company's
separate plan are included in accrued retiree benefits and other long-term
liabilities on the balance sheet. The Parent funds annually those pension costs
which are calculated in accordance with Internal Revenue Service regulations
and standards issued by the Cost Accounting Standards Board.


FAIR VALUE OF FINANCIAL INSTRUMENTS

The carrying value of certain financial instruments including cash and cash
equivalents and the current portion of long-term debt approximates fair value
due to their short maturities and varying interest rates. The carrying value of
long-term debt, which approximates fair value, is based on current rates
offered to the Company for similar debt with the same remaining maturities.


ACCOUNTING STANDARDS

In October 2001, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards No. 144, Accounting for the
Impairment or Disposal of Long-Lived Assets (SFAS No. 144). This accounting
standard, which is effective for fiscal years beginning after December 31,
2001, requires that long-lived assets that are to be disposed of by sale be
measured at the lower of book value or fair value less cost to sell.
Additionally, SFAS No. 144 expands the scope of discontinued operations to
include all components of an entity with operations that can be distinguished
from the rest of the entity and will be eliminated from the ongoing operations
of the entity in a disposal transaction. The effect of adopting SFAS No. 144 on
the Company's financial position and results of operations has not yet been
determined.

In June 2001, the FASB issued Statement of Financial Accounting Standards No.
142, Goodwill and Other Intangible Assets (SFAS No. 142). This accounting
standard addresses financial accounting and reporting for goodwill and other
intangible assets and requires that goodwill amortization be discontinued and
replaced with periodic tests of impairment. SFAS No. 142 is effective for
fiscal years beginning after December 15, 2001, and is required to be applied
at the beginning of the fiscal year. Impairment losses that arise due to the
initial application of this standard will be reported as a change in accounting
principle. The Company has not completed its analysis of the effect of adopting
SFAS No. 142, however the Company expects that this analysis will result in a
goodwill impairment loss in the first quarter of 2002.

Effective January 1, 2001, the Company adopted Statement of Financial
Accounting Standards No. 133, Accounting for Derivative Instruments and Hedging
Activities (SFAS No. 133). This accounting standard requires that all
derivatives be recognized as either assets or liabilities at estimated fair
value. The Company also adopted Statement of Financial Accounting Standards No.
138, Accounting for Certain Derivative Instruments and Certain Hedging
Activities, an amendment of SFAS No. 133. This accounting standard amended the
accounting and reporting standards of SFAS No. 133 for certain derivative
instruments and hedging activities. The January 1, 2001 adoption of SFAS No.
133, as amended, had no effect on the Company's financial position or results
of operations.


RISKS AND UNCERTAINTIES

The Company is engaged in supplying primarily defense-related equipment to U.S.
and foreign governments and is subject to certain business risks peculiar to
the defense industry. Sales to governments may be affected by changes in
procurement policies, budget considerations, changing concepts of national
defense, political developments abroad, and other factors.

                     AIRCRAFT INTEGRATION SYSTEMS BUSINESS
             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)

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 and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Significant estimates are used when accounting for long-term contracts including
estimates of the extent of progress towards completion, contract revenue,
contract completion costs, contingencies, and customer and vendor claims, as
well as estimates for litigation and environmental liabilities. Actual results
could differ from those estimates.


3. RESTRUCTURING

Restructuring costs include the cost of involuntary employee termination
benefits and related employee severance costs, facility closures, and other
costs associated with the Company's approved plans. Employee termination
benefits include severance, wage continuation, medical, and other benefits.
Facility closure and related costs include disposal costs of property, plant,
and equipment, lease payments, and lease terminations costs.

The Parent created Raytheon Systems Company (RSC) in December 1997, which
included the Company. In conjunction with the formation of RSC, the Parent
established certain restructuring reserves. A portion of these reserves was for
actions related to the Company.

In 1999, the Company determined that the cost of the restructuring initiatives
would be higher than originally planned and recorded a $7.8 million
restructuring charge which was included in cost of sales. The increase in the
estimated costs related to higher than anticipated costs for severance. The
Company also recorded an additional $0.7 million restructuring charge in 1999,
which was included in cost of sales, to further reduce the manufacturing and
administrative workforce by 39 employees.

The restructuring and exit costs discussed above provided for severance and
related benefits for approximately 400 employees. There were no major
activities that were continued as a result of these actions. Employee-related
exit costs included severance and other termination benefit costs for employees
in various functional areas including manufacturing, engineering, and
administration. The Company completed all restructuring actions during 2000.
While these actions were intended to improve the Company's competitive
position, there can be no assurances as to their ultimate success or that
additional restructuring actions will not be required.

Restructuring activity is as follows (in millions):




                                                                             2000        1999

4. PARENT COMPANY INVESTMENT AND INTERCOMPANY COST ALLOCATIONS


PARENT COMPANY INVESTMENT

The Company has obtained financing for its day-to-day operations from the
Parent. Parent company investment includes the Parent's equity investment in
the Company and net amounts due to the Parent.


                                      A-9


                     AIRCRAFT INTEGRATION SYSTEMS BUSINESS
             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)

Neither intercompany interest expense nor interest expense associated with the
Parent's general corporate debt has been included in the combined financial
statements. All transfers to and from the Parent have been reported in the
parent company investment account.


INTERCOMPANY COST ALLOCATIONS


Certain costs are allocated to the Company by the Parent, primarily related to
certain services, legal expenses, information systems, risk management and
employee benefits (see Note 12 for further disclosure regarding employee
benefits). The estimated costs of such services and benefits have been included
in the combined financial statements based primarily on the proportion of the
Parent's expenses allocated to the Company based on factors including employee
headcount and costs incurred. Management believes these allocations are
reasonable.


The amounts allocated to the Company in 2001, 2000, and 1999 in the combined
statement of operations are as follows (in millions):






                                                     2001          2000          1999

The U.S. government has title to the costs incurred underlying unbilled amounts
on contracts that provide for progress payments. Unbilled amounts are primarily
recorded on the percentage of completion method and are recoverable from the
customer upon shipment of the product, presentation of billings, or completion
of the contract.


Included in contracts in process at December 31, 2001 was approximately $11
million related to claims on contracts, which are included at their estimated
realizable value. The Company believes that it has a contractual or legal basis
for pursuing recovery of these claims, and that collection is probable. The
settlement of these amounts depends on individual circumstances and
negotiations with the counterparty, therefore, the timing of the collection
will vary. There were no such claim amounts included in contracts in process at

The Parent adopted the disclosure-only provisions of Statement of Financial
Accounting Standards No. 123, Accounting for Stock Based Compensation (SFAS No.
123) and accordingly, no compensation expense has been recognized for the Stock
Option Plan. Had compensation cost for the stock options awarded to the
employees of the Company been determined based on the fair value at the grant
date for awards under the Stock Option Plan, consistent with the methodology
prescribed under SFAS No. 123, the Company's net income in 2001, 2000, and 1999
would include an additional $1.8 million, $2.4 million, and $1.5 million of
compensation expense, respectively.

The weighted-average fair value of each option granted in 2001, 2000, and 1999,
respectively, was estimated at $9.24, $5.86, and $22.60 on the date of grant
using the Black-Scholes option pricing model with the following assumptions:

As noted above, the Company also contributes to multiemployer pension and other
employee benefit plans administered by Raytheon Company, and contributed and
charged to expense $13.3 million, $12.9 million, and $26.0 million in 2001,
2000, and 1999, respectively.

Under the terms of various savings and investment plans (defined contribution
plans), covered employees are allowed to contribute up to a specific percentage
of their pay, generally limited to $30,000 per year. The Company matches the
employee's contribution, up to a certain percent of the employee's pay. Total
expense for defined contribution plans was $9.2 million, $10.1 million, and
$10.4 million in 2001, 2000, and 1999, respectively.

The Company makes annual contributions to the Raytheon Company stock fund of
the various savings and investment plans of approximately one-half of one
percent of salaries and wages, limited to $170,000 in 2001, 2000, and 1999, of
most U.S. salaried and hourly employees. The expense was $1.4 million, $1.5
million, and $1.6 million in 2001, 2000, and 1999, respectively.

million, respectively.

The Company has banks and insurance companies issue, on its behalf, letters of
credit to meet various bid, warranty, retention, and advance payment
obligations, $133.7 million of which were outstanding at December 31, 2001.
Approximately $32.8 million of this total relates to letters of credit issued
to meet performance clauses in certain contracts. These instruments expire on
various dates in 2002.

Government contractors are subject to various levels of audit and
investigation. Agencies that oversee contract performance include: the Defense
Contract Audit Agency, the Department of Defense Inspector General, the General
Accounting Office, the Department of Justice, and Congressional Committees.

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)

In addition, various claims and legal proceedings generally incidental to the
normal course of business are pending or threatened against the Company. While
the ultimate liability from these proceedings is presently indeterminable, any
additional liability is not expected to have a material adverse effect on
the Company's financial position or results of operations after giving effect to
provisions already recorded.

In connection with this agreement the Parent will retain certain assets and
liabilities of the business, including all amounts related to taxes and
employee benefits. There can be no assurance that the sale will be consummated.

                                      B-1


UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL INFORMATION


     The following unaudited pro forma condensed consolidated statement of
operations ("pro forma statement of operations") data gives effect to the
following transactions as if they had occurred on January 1, 2001: (1) the
acquisition by L-3 Communications Corporation ("L-3 Communications") of Aircraft
Integration Systems ("AIS"), a portion of a reportable segment of Raytheon
Company ("Raytheon") which was completed on March 8, 2002 and the related
financing which was comprised of cash on hand, borrowings under L-3
Communications' senior credit facilities and a $500.0 million senior
subordinated bridge loan; and (2) certain other businesses acquired during the
year ended December 31, 2001 (the "Other Acquisitions"), comprised of KDI
Precision Products, Inc., EER Systems, Inc., Spar Aerospace Limited, Emergent
Government Services Group, Bulova Technologies, and SY Technology, Inc., and
their related financings. L-3 Communications is a wholly-owned subsidiary of L-3
Communications Holdings, Inc. ("L-3 Holdings"). L-3 Holdings and its
subsidiaries, including L-3 Communications, are referred to as "L-3" herein.


     The unaudited pro forma condensed consolidated balance sheet ("pro forma
balance sheet") gives effect to the AIS acquisition as if it had occurred on
December 31, 2001. All of the Other Acquisitions are included in the Company's
consolidated balance sheet as of December 31, 2001.


     The pro forma adjustments are based on preliminary purchase prices and
purchase price allocations for the AIS acquisition and Other Acquisitions.
Actual adjustments will be based on final purchase prices and final appraisals
and other analyses of fair values of the acquired businesses for contracts in
process, inventories, estimated costs in excess of billings to complete
contracts in process, identifiable intangibles, pension and postretirement
benefit obligations and deferred tax assets and liabilities, which will be
completed after L-3 obtains and reviews all of the data required for the
acquired assets and liabilities and completes its valuations of them.
Differences between the preliminary and final purchase price allocations could
have a material impact on L-3's results of operations and financial position.
The unaudited pro forma condensed consolidated statement of operations and
unaudited pro forma condensed consolidated balance sheet do not reflect any
cost savings that management of L-3 believes would have resulted had the AIS
acquisition and Other Acquisitions occurred on January 1, 2001.


     The unaudited pro forma condensed consolidated financial information should
be read in conjunction with (1) the audited consolidated financial statements of
L-3 Holdings and L-3 Communications included in their annual report on Form 10-K
for the year ended December 31, 2001; and (2) the audited combined financial
statements of AIS for the year ended December 31, 2001 included elsewhere in
this report on Form 8-K. The historical statement of operations data for the
Other Acquisitions are based on unaudited financial statement data not included
herein. The unaudited pro forma condensed consolidated financial information may
not be indicative of the results of operations of L-3 that actually would have
occurred had the acquisitions been completed on January 1, 2001 or the results
of operations of L-3 that may be obtained in the future.

                     NOTES TO UNAUDITED PRO FORMA CONDENSED
                       CONSOLIDATED FINANCIAL STATEMENTS

1. On March 8, 2002, L-3 Communications acquired AIS, a portion of a
   reportable segment of Raytheon, for $1,152.7 million in cash which includes
   $1,130.0 million for the original contract purchase price, $4.0 million for
   estimated acquisition costs and an increase to the contract purchase price
   of $18.7 million related to additional assets contributed by Raytheon to
   AIS. The purchase price is subject to adjustment based on the AIS closing
   date net tangible book value, as defined. The acquisition was financed
   using cash on hand, available borrowings under L-3 Communications' senior
   credit facilities and a $500.0 million senior subordinated bridge loan.

   L-3 expects to offer and sell approximately $1.0 billion of debt and equity
   securities during the first half of 2002, depending on capital market
   conditions, and use the proceeds from the offerings to repay the $500.0
   million senior subordinated bridge loan and repay the outstanding balance
   under the senior credit facilities. The unaudited pro forma condensed
   consolidated financial statements do not give effect to these anticipated
   refinancings for the AIS acquisition.

2. The pro forma balance sheet includes adjustments to remove AIS historical
   assets and liabilities at December 31, 2001 which were not included in the
   AIS acquisition. The excluded assets and liabilities are comprised of cash
   and cash equivalents of $4.0 million, receivables due from Raytheon of $7.4
   million, current deferred tax assets of $13.3 million, and non-current
   deferred tax liabilities of $12.5 million.

3. The estimated excess of purchase price over fair value of identifiable net
   assets acquired (goodwill) for AIS is $780.8 million and is not being
   amortized in accordance with Statement of Financial Accounting Standard
   (SFAS) No. 142 Goodwill and Other Intangibles because the AIS acquisition
   was completed after June 30, 2001. Additionally, the pro forma balance
   sheet includes the elimination of $940.1 million of goodwill included in
   the AIS historical balance sheet, and $1,381.2 million of AIS historical
   parent company invested equity. The pro forma balance sheet also reflects
   the following related to the preliminary AIS purchase price allocation:

   (a)        no adjustment has been made to contracts in process which will
              be valued at their estimated contract prices less the estimated
              costs to complete and an allowance for a normal profit on the
              effort to complete such contracts. All of the data required to
              prepare these valuations is not currently available and at this
              time it is not practicable to reasonably estimate these
              valuations.

   (b)        a review of the identifiable intangible assets included in the
              AIS acquisition will be performed. All of the data required to
              prepare this review and the related valuations is not currently
              available and at this time it is not practicable to reasonably
              estimate these valuations. Any allocation of purchase price to
              identifiable intangible assets with finite lives will result in
              additional amortization expense and a reduction to the goodwill
              estimate of AIS;

   (c)        an increase to pension and postretirement benefits liabilities
              of $95.0 million to reflect the benefit obligations assumed by
              L-3 in accordance with SFAS No. 87 Employers' Accounting for
              Pensions and SFAS No. 106 Employers' Accounting for
              Postretirement Benefits Other Than Pensions; and

   (d)        an increase in other assets of $38.0 million to reflect the
              deferred tax asset related to the increase in the AIS pension and
              postretirement benefits obligations.

4. The adjustment to costs and expenses relating to the AIS acquisition in the
   pro forma statement of operations for the year ended December 31, 2001
   represents the elimination of goodwill amortization expense included in the
   historical financial statements of AIS of $27.8 million. In accordance with
   SFAS No. 142, no goodwill amortization is reflected for L-3's goodwill
   resulting from the acquisition of AIS.

                     NOTES TO UNAUDITED PRO FORMA CONDENSED
               CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

5. The purchase price including acquisition costs for the AIS acquisition of
   $1,152.7 million was financed using (1) borrowings under L-3
   Communications' senior credit facilities of $420.0 million, (2) a $500.0
   million senior subordinated bridge loan and (3) cash on hand of $232.7
   million. The cash on hand of $232.7 million was assumed to be a use of the
   net proceeds from L-3 Holdings' sale of $420.0 million of 4% Senior
   Subordinated Convertible Contingent Debt Securities due September 15, 2011
   ("CODES") in October and November of 2001 which amounted to $407.5 million.
   The remaining portion of the net proceeds from the CODES offering were used
   to partially finance the Other Acquisitions (See Note 10). The adjustments
   to L-3's pro forma interest expense for the year ended December 31, 2001 to
   give effect to the financing of the AIS acquisition are based on the
   average prevailing interest rates during 2001 on the related borrowings and
   the assumed completion of the CODES offering on January 1, 2001, and are
   presented below.






                                                                                ($ in millions)

   Additionally, L-3's historical interest income for the year ended December
   31, 2001 has been adjusted to eliminate the interest income of $1.0 million
   earned on investments in cash and cash equivalents for the $232.7 million
   portion of the net proceeds from the CODES offering that was assumed to be
   used to finance the AIS acqusition.

----------
   (a)        Represents historical results of operations for the four-month
              period ended April 30, 2001.

   (b)        Represents historical results of operations for the ten-month
              period ended October 31, 2001.

   (c)        Represents historical results of operations for the eleven-month
              period ended November 30, 2001.

   (d)        Includes a charge to write-down excess inventory of $1.7
              million.

   (e)        Includes a charge of $4.2 million for investment banking fees
              and other non-recurring charges.

   (f)        Includes a $3.3 million gain on the sale of discontinued
              operations and a $1.4 million restructuring charge.

   (g)        Includes a $3.8 million restructuring charge.


   The historical results of operations for KDI, EER, BT Fuze and SY do not
   include a provision for income taxes because they each were either an S
   Corporation or Limited Liability Corporation and the income taxes on their
   income were paid by their individual stockholders rather than by them.

9.   Adjustments to costs and expenses relating to the Other Acquisitions in the
     pro forma statement of operations for the year ended December 31, 2001
     amounted to a net decrease of $1.1 million and were comprised of (1) an
     increase to goodwill amortization expense of $0.7 million for the KDI and
     EER acquisitions for the higher goodwill amounts recorded by L-3 for these
     acquisitions compared to their historical goodwill amounts and (2) the
     elimination of historical goodwill amortization expense of $1.2 million for
     EMG and $0.6 million for Spar. In accordance with the provisions of SFAS
     No. 142, no goodwill amortization is recorded on EMG, Spar, BT Fuze and SY.

10.  The aggregate purchase price including acquisition costs for the Other
     Acquisitions of $484.9 million was financed using cash on hand which
     assumed to be a use of (1) the net proceeds from L-3 Holdings'


                                      B-7


                       L-3 COMMUNICATIONS HOLDINGS, INC.
                       AND L-3 COMMUNICATIONS CORPORATION


                     NOTES TO UNAUDITED PRO FORMA CONDENSED
               CONSOLIDATED FINANCIAL STATEMENTS -- (CONCLUDED)

     public offering of 4,575,000 shares of L-3 Holdings, Inc. common stock in
     May 2001 (the "May 2001 Common Stock Offering") which amounted to $353.6
     million, and (2) the remaining net proceeds of $174.8 million from L-3
     Holdings' CODES offering after the portion of the CODES offering assumed to
     be used to finance $232.7 million of the AIS acquisition (see Note 5). The
     adjustment to L-3's pro forma interest expense for the year ended December
     31, 2001 to give effect to the financing of the Other Acquisitions is $6.6
     million and was calculated on the $187.3 million of the remaining principal
     amount of the CODES assuming the completion of the CODES offering on
     January 1, 2001 (4% on $187.3 million for the ten-month period ended
     October 31, 2001 and $0.4 million for amortization of deferred debt issue
     costs).

     Additionally, L-3 Holdings' basic and diluted weighted average shares
     outsanding for the year ended December 31, 2001 were each increased by 1.5
     million shares of common stock to give effect to the assumed completion of
     the May 2001 Common Stock Offering as of January 1, 2001.

     Additionally, L-3's historical interest income for the year ended December
     31, 2001 was adjusted to eliminate the interest income of $0.7 million
     earned on investments in cash and cash equivalents for the $174.8 million
     portion of the net proceeds from the CODES offering that was assumed to be
     used to finance the Other Acqusitions.


11.  The pro forma adjustments for the Other Acquisitions were tax-effected, as
     appropriate, using an estimated statutory (federal and state) tax rate of
     40.0%. The pro forma adjustments also include an income tax provision of
     $1.1 million to record the aggregate income tax expense for the historical
     results of operations of KDI, EER, BT Fuze and SY to the statutory income
     tax rate of 40.0% that they would have incurred, but did not because they
     were not subject to income tax prior to their acquisition by L-3.


12.  All the assets and liabilities of the Other Acquisitions, the CODES
     Offering and the May 2001 Common Stock Offering are included in L-3's
     balance sheet at December 31, 2001. Accordingly, L-3's December 31, 2001
     balance sheet is not adjusted to give effect to these transactions.


13.  L-3 Holdings' diluted weighted average shares outstanding and diluted
     earnings per share give effect to the assumed conversion of the 3,680,982
     shares issuable upon the conversion of L-3 Holdings $300.0 million of
     5 1/4% Convertible Senior Subordinated Notes due 2009. The assumed
     conversion results in the addition of $10.5 million of after-tax interest
     expense savings to reported net income for the year ended
     December 31, 2001 for the purposes of calculating diluted earnings per
     share.
