Available borrowings under the Company's senior credit facilities at June 30, 2003 were $669,397, after reductions for outstanding letters of credit of $80,603. There were no borrowings outstanding under the senior credit facilities at June 30, 2003. On February 25, 2003, the maturity date of the $250,000 364-day revolving credit facility was extended to February 24, 2004.

On May 21, 2003, L-3 Communications sold $400,000 of 6 1/8% Senior Subordinated Notes due July 15, 2013 (May 2003 Notes) at a discount of $1,840, or $398,160. The discount was recorded as a reduction to the principal amount of the notes and will be amortized as interest expense over the term of the notes. The effective interest rate of the May 2003 Notes is 6.17% per annum. Interest is payable semi-annually on January 15 and July 15 of each year, commencing July 15, 2003. The net cash proceeds from this offering amounted to approximately $391,000 after deducting the discounts, commissions and other offering expenses. The net proceeds from this offering were used to redeem the 8½% Senior Subordinated Notes due 2008 and increase cash and cash equivalents. The May 2003 Notes are general unsecured obligations of L-3 Communications and are subordinated in right of payment to all existing and future senior debt of L-3 Communications. The May 2003 Notes are subject to redemption at any time, at the option of L-3 Communications, in whole or in part, on or after July 15, 2008 at redemption prices (plus accrued and unpaid interest) starting at 103.063% of the principal amount (plus accrued and unpaid interest) during the 12-month period beginning July 15, 2008 and declining annually to 100% of principal (plus accrued and unpaid interest) on July 15, 2011 and thereafter. Prior to July 15, 2006, L-3 Communications may redeem up to 35% of the May 2003 Notes with the proceeds of certain equity offerings at a redemption price of 106.125% of the principal amount (plus accrued and unpaid interest).

On May 21, 2003, L-3 Communications initiated a full redemption of all its outstanding $180,000 aggregate principle amount of 8½% Senior Subordinated Notes due 2008 (May 1998 Notes). On June 20, 2003, L-3 Communications purchased and paid cash for all the outstanding May 1998 Notes including accrued interest. For the six months ended June 30, 2003, L-3 Communications recorded a pre-tax charge of $11,225, comprising of premiums and other transaction costs of $7,795 and $3,430 to write-off the unamortized balance of debt issue costs and the deferred loss on the terminated interest rate swap agreements related to the May 1998 Notes.

In January of 2003, L-3 Communications entered into interest rate swap agreements on $200,000 of its 7 5/8% Senior Subordinated Notes due 2012. These swap agreements exchanged the fixed interest rate for a variable interest rate on $200,000 of the $750,000 principal amount outstanding. In March of 2003, L-3 Communications terminated these interest rate swap agreements and received cash proceeds of $6,440. Prior to the termination of the swap agreements, L-3 Communications recorded a reduction to interest expense for the six months ended June 30, 2003 of $1,202. This reduction represented interest savings earned for the period prior to the termination of these swap agreements. The average variable interest rate the Company paid under the swap agreements was 4.0% compared to the 7 5/8% fixed interest rate on the notes subject to the swaps. The remaining $5,238 of the proceeds represented the future value of the swap agreements at the termination date and was recorded as a deferred gain. The deferred gain is being amortized as a reduction to interest expense over the remaining term of the 7 5/8% Senior Subordinated Notes due 2012 at an amount of $142 per quarter, or $566 annually.

rate the Company paid under the swap agreements was 4.4% compared to the 7 5/8% fixed interest rate on the notes subject to the swaps. The remaining $6,727 of the proceeds represented the future value of the swap agreements at the termination date and was recorded as a deferred gain. The deferred gain is being amortized as a reduction to interest expense over the remaining term of the 7 5/8% Senior Subordinated Notes due 2012 at an amount of $187 per quarter, or $747 annually.

The aggregate unamortized net deferred gains recorded in connection with the terminations of the interest rate swap agreements were $27,371 at June 30, 2003 and $16,140 at December 31, 2002. These net deferred gains will be amortized as reductions to interest expense through 2012. The current portion of the net deferred gains of $3,426 at June 30, 2003 and $2,114 at December 31, 2002 that will be amortized over the next 12 months is included in accrued interest. The non-current portions of the net deferred gains is included in other liabilities.

11.	Contingencies

The Company is engaged in providing products and services under contracts directly or as a subcontractor to the U.S. Government and, to a lesser degree, under foreign government contracts, some of which are funded by the U.S. Government. All such contracts are subject to extensive legal and regulatory requirements, and, from time to time, agencies of the U.S. Government investigate whether such contracts were and are being conducted in accordance with these requirements. Under U.S. Government procurement regulations, an indictment of the Company by a federal grand jury could result in the Company being suspended for a period of time from eligibility for awards of new government contracts. A conviction could result in debarment from contracting with the federal government for a specified term. Additionally, in the event that U.S. Government expenditures for products and services of the type manufactured and provided by the Company are reduced, and not offset by greater commercial sales or other new programs or products, or acquisitions, there may be a reduction in the volume of contracts or subcontracts awarded to the Company. In addition, all of our domestic government contracts and subcontracts are subject to audit and various cost controls, and include standard provisions for termination for the convenience of the U.S. Government. Multiyear U.S. Government contracts and related orders are subject to cancellation if funds for contract performance for any subsequent year become unavailable. Foreign government contracts generally include comparable provisions relating to termination for the convenience of the relevant foreign government.

Management continually assesses the Company's obligations with respect to applicable environmental protection laws. While it is difficult to determine the timing and ultimate cost to be incurred by the Company in order to comply with these laws, based upon available internal and external assessments, with respect to those environmental loss contingencies of which management is aware, the Company believes that even without considering potential insurance recoveries, if any, there are no environmental loss contingencies that, individually or in the aggregate, would be material to the Company's consolidated results of operations. The Company accrues for these contingencies when it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated.

On August 6, 2002, Aviation Communications & Surveillance Systems, LLC (ACSS) was sued by Honeywell International Inc. and Honeywell Intellectual Properties, Inc. (collectively, "Honeywell") for

18

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

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—CONTINUED
(Dollars in thousands, except per share data)

alleged infringement of patents that relate to terrain awareness avionics. The lawsuit was filed in the United States District Court for the District of Delaware. In December of 2002, Honeywell withdrew without prejudice the lawsuit against ACSS and agreed to proceed with non-binding arbitration. The arbitration was held during the week of July 28th, and the parties are awaiting the arbitrators decision, which will be delivered on August 22, 2003. If the matter is not resolved through arbitration, Honeywell may reinstitute the litigation after August 22, 2003. The Company had previously investigated the Honeywell patents and believes that ACSS has valid defenses against Honeywell's patent infringement suit. In addition, ACSS has been indemnified to a certain extent by Thales Avionics, which provided ACSS with the alleged infringing technology. Thales Avionics owns 30% of ACSS. In the opinion of management, the ultimate disposition of Honeywell's pending claim will not result in a material liability to the Company.

On November 18, 2002, the Company initiated a proceeding against OSI Systems, Inc. (OSI) in the United States District Court sitting in the Southern District of New York (the "New York action") seeking, among other things, a declaratory judgment that the Company had fulfilled all of its obligations under a letter of intent with OSI (the "OSI Letter of Intent"). Under the OSI Letter of Intent, the Company was to negotiate definitive agreements with OSI for the sale of certain businesses the Company acquired from PerkinElmer, Inc. on June 14, 2002. On December 23, 2002, OSI responded by filing suit against the Company in the United States District Court sitting in the Central District of California (the "California action") alleging, among other things, that the Company breached its obligations under the OSI Letter of Intent and seeking damages in excess of $100 million, not including punitive damages. On February 7, 2003, OSI filed an answer and counterclaims in the New York action that asserted substantially the same claims OSI had raised in the California action. The California action was dismissed by the California District Court in favor of the New York action. Under the OSI Letter of Intent, the Company proposed selling to OSI the conventional detection business and the ARGUS business that the Company recently acquired from PerkinElmer, Inc. Negotiations with OSI lasted for almost one year and ultimately broke down over issues regarding, among other things, intellectual property, product-line definitions, allocation of employees and due diligence. The Company believes that the claims asserted by OSI in its suit are without merit and intends to defend against the OSI claims vigorously.

The Company is periodically subject to litigation, claims or assessments and various contingent liabilities incidental to its business. With respect to those investigative actions, items of litigation, claims or assessments of which they are aware, management of the Company is of the opinion that the probability is remote that, after taking into account certain provisions that have been made with respect to these matters, the ultimate resolution of any such investigative actions, items of litigation, claims or assessments will have a material adverse effect on the consolidated financial position, results of operations or cash flows of the Company.

12.	Segment Information

The Company has four reportable segments: (1) Secure Communications & ISR, (2) Training, Simulation & Support Services, (3) Aviation Products & Aircraft Modernization and (4) Specialized Products, which are described in Note 1. The Company evaluates the performance of its operating segments and reportable segments based on their sales and operating income.

13.	Recently Issued Accounting Standards

In January of 2003, the FASB issued FASB Interpretation No. 46, Consolidation of Variable Interest Entities (FIN 46). This interpretation provides guidance on the identification of, and financial reporting for, entities over which control is achieved through means other than voting rights. Such entities have been termed by FIN 46 as variable interest entities (VIE). Once effective, FIN 46 will be the guidance that determines (1) whether consolidation is required under the "controlling financial interest" model of ARB Bulletin No. 51, Consolidated Financial Statements, or (2) whether the variable-interest model under FIN 46 should be used to account for existing and new entities. FIN 46 includes guidance for identifying the enterprise that will consolidate a VIE, which is the enterprise that is exposed to the majority of an entity's risks or receives the majority of the benefits from an entity's activities. FIN 46 also requires that the enterprises that hold a significant variable interest in a VIE make new disclosures in their financial statements. The transitional disclosures of FIN 46, which are effective immediately, require an enterprise

20

(Dollars in thousands, except per share data)

to identify the entities in which it holds a variable interest, if the enterprise believes that those entities might be considered VIEs upon the adoption of FIN 46. The implementation and remaining disclosure requirements of FIN 46 are effective immediately for VIEs created after January 31, 2003, and on July 1, 2003 for all VIEs created before January 31, 2003. The Company does not hold any interests in VIEs that would require consolidation or additional disclosures.

In March of 2003, the Emerging Issues Task Force (EITF) issued EITF No. 00-21, Accounting for Revenue Arrangements with Multiple Deliverables. EITF No. 00-21 addresses how to determine whether a contractual arrangement involving multiple deliverables contains more than one accounting unit and how consideration should be measured and allocated to the separate accounting units. EITF No. 00-21 applies to all deliverables within contractually binding arrangements in all industries, except to the extent that a deliverable in a contractual arrangement is subject to other existing higher-level authoritative literature, and is effective for revenue arrangements entered into in fiscal periods beginning after June 15, 2003. The Company is currently evaluating the effect of EITF No. 00-21 on the Company's revenue recognition accounting policies and on its consolidated results of operations and financial position.

In May of 2003, the FASB issued SFAS No. 150, Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity. This Statement applies to certain financial instruments including mandatorily redeemable financial instruments that, prior to SFAS No. 150 could have been accounted for as a component of equity. SFAS No. 150 requires that those instruments be classified as liabilities in statements of financial position. SFAS No. 150 also requires disclosures about alternative ways of settling the instruments and the capital structure of entities whose shares are all mandatorily redeemable. SFAS No. 150 is effective for these financial instruments entered into or modified after May 31, 2003. For these financial instruments entered into before May 31, 2003, SFAS No. 150 is effective for the Company's interim period beginning July 1, 2003. The Company does not hold any financial instruments that are within the scope of SFAS No. 150 and it is not expected to have a material effect on the Company's consolidated results of operations or financial position.

14.	Unaudited Financial Information of L-3 Communications and its Subsidiaries

L-3 Communications is a wholly owned subsidiary of L-3 Holdings. The debt of L-3 Communications, including its outstanding Senior Subordinated Notes and borrowings under amounts drawn against the senior credit facilities are guaranteed, on a joint and several, full and unconditional basis, by certain of its wholly-owned domestic subsidiaries (the "Guarantor Subsidiaries"). The foreign subsidiaries and certain domestic subsidiaries of L-3 Communications (the "Non-Guarantor Subsidiaries") do not guarantee the debt of L-3 Communications. None of the debt of L-3 Communications has been issued by its subsidiaries. There are no restrictions on the payment of dividends from the Guarantor Subsidiaries to L-3 Communications.

The following unaudited condensed combining financial information present the results of operations, financial position and cash flows of (i) L-3 Holdings, excluding L-3 Communications and its consolidated subsidiaries, (ii) L-3 Communications, excluding its consolidated subsidiaries (the "Parent"), (iii) the Guarantor Subsidiaries, (iv) the Non-Guarantor Subsidiaries and (v) the eliminations to arrive at the information for L-3 Communications on a consolidated basis.

(1)	The purchase price represents the contractual consideration for the acquired business excluding adjustments for net cash acquired and acquisition costs.

(2)

Includes $18.7 million related to additional assets contributed by Raytheon Company (Raytheon) to Aircraft Integration Systems. Following the acquisition, we changed AIS's name to L-3 Communications Integrated Systems (IS). The purchase price is subject to adjustment based on actual closing date tangible net assets, as discussed in Note 4 to the unaudited condensed consolidated financial statements.

(3)	Includes a $10.0 million preliminary purchase price adjustment. The purchase price is subject to further adjustment based on actual closing date net working capital.

(4)

The purchase price consists of $14.5 million of cash, 229,494 shares of L-3 Holdings common stock valued at $10.6 million and an additional 109,514 shares of L-3 Holdings common stock valued at $5.0 million. The additional 109,514 shares are expected to be issued during the third quarter of 2003 because ComCept achieved its financial performance target for the fiscal year ended June 30, 2003. Excludes additional purchase price in the form of L-3 Holdings common stock, which is contingent upon the financial performance of ComCept for the fiscal year ending June 30, 2004. The maximum additional L-3 Holdings common stock payable is 109,544 shares.

(5)	The purchase price is subject to adjustment based on actual closing date net assets or net working capital of the acquired business.

(6)	Excludes additional purchase price, not to exceed $7.0 million, which is contingent upon the financial performance of TMA for the twelve months ending September 30, 2003. Following the acquisition, we changed TMA's name to L-3 Communications TMA Corporation.

(9)	Excludes additional purchase price, not to exceed $5.0 million, which is contingent upon the financial performance of IMC for the year ending December 31, 2003.

(10)	Excludes additional purchase price, not to exceed $13.5 million, which is contingent upon the financial performance of Ship Analytics for the years ending December 31, 2003, 2004 and 2005.

(11)	Following the acquisition, we changed the name of Avionics Systems to L-3 Communications Avionics Systems, Inc.

Additionally, we purchased other businesses and product-lines during the six months ended June 30, 2003 and during the year ended December 31, 2002, which individually and in the aggregate were not material to our consolidated results of operations, financial position or cash flows for the period acquired.

26

The aggregate purchase price for these businesses and product-lines was $7.0 million, and the increase to sales from these businesses and product-lines for the six months ended June 30, 2003 compared to the six months ended June 30, 2002 was $1.2 million. All of our acquisitions have been accounted for as purchase business combinations and are included in our consolidated results of operations from their respective effective dates.

In June of 2003, we entered into an agreement to acquire the Military Aviation Services business of Bombardier, Inc. for approximately $90.0 million in cash. The acquisition is subject to regulatory approval and is expected to be completed in September 2003.

We regularly evaluate potential acquisitions and joint venture transactions, but we have not entered into any other agreements with respect to any material transactions at this time.

Results of Operations

The following information should be read in conjunction with our unaudited condensed consolidated financial statements. Our results of operations for the periods presented are impacted significantly by our acquisitions. See Note 4 to the unaudited condensed consolidated financial statements for a discussion of our acquisitions, including pro forma sales, net income and diluted earnings per share data for the three months ended June 30, 2003 (2003 Second Quarter) and June 30, 2002 (2002 Second Quarter) and for the six months ended June 30, 2003 (2003 First Half) and June 30, 2002 (2002 First Half).

We present our sales and costs and expenses in two categories on the statement of operations, "Contracts, primarily U.S. Government" and "Commercial, primarily products," which are based on how we recognize revenue. Sales and costs and expenses for L-3's businesses that are primarily U.S. Government contractors are presented as "Contracts, primarily U.S. Government." The sales for L-3's U.S. Government contractor businesses are transacted using written contractual arrangements or contracts for products and services according to the specifications provided by the customer and are within the scope of SOP 81-1 and ARB 43. Sales reported under "Contracts, primarily U.S. Government" also include certain sales by L-3's U.S. Government contractor businesses transacted using contracts for domestic and foreign commercial customers which also are within the scope of SOP 81-1. Sales and costs and expenses for L-3's businesses whose customers are primarily commercial customers are presented as "Commercial, primarily products". These sales to commercial customers are recognized in accordance with SEC SAB No. 101 and are not within the scope of SOP 81-1 or ARB 43. L-3's commercial businesses are substantially comprised of Aviation Communication & Surveillance Systems (ACSS), Aviation Recorders, Microwave components, Detection Systems, Avionics Systems, Satellite Networks, and PrimeWave Communications.

(1)	Sales are after intersegment eliminations. See Note 12 to the unaudited condensed consolidated financial statements.

Consolidated sales increased $271.7 million to $1,226.9 million for the 2003 Second Quarter from sales of $955.2 million for the 2002 Second Quarter. Sales grew $88.9 million, or 9.3%, excluding the increase in sales from acquired businesses of $182.8 million discussed below. We expect our consolidated sales growth for the full year 2003 to be between 8% and 10%, excluding acquisitions and excluding the expected decline of $209 million for sales of explosives detection systems (EDS) to $130 million from $339 million for 2002 as discussed below under "Specialized Products." We expect our Secure Communications & ISR businesses to be the largest contributor to L-3's sales growth for 2003.

Sales from "Contracts, primarily U.S. Government" increased $217.3 million to $1,081.1 million for the 2003 Second Quarter from $863.8 million for the 2002 Second Quarter. The Telos, ComCept, TMA, Electron Devices, Ruggedized Command & Control, Westwood, Wescam, Ship Analytics and Aeromet acquired businesses contributed $115.2 million of the increase in sales. Excluding these acquisitions, sales grew $102.1 million, or 11.8%, primarily because of continued strong demand in our defense businesses.

28

The increases include $66.1 million for secure communications and ISR systems and products, $36.9 million for aircraft modernization, $23.5 million for communications software and engineering support services, $9.4 million for naval power equipment, and $4.3 million for training services. These increases were partially offset by volume declines of $10.6 million for fuzing products, $7.6 million for training devices, $5.6 million for security products, $5.2 million for acoustic undersea warfare products, $2.4 million for display systems and $6.7 million primarily for telemetry, space and navigation products.

Sales from "Commercial, primarily products" increased $54.4 million to $145.8 million for the 2003 Second Quarter from $91.4 million for the 2002 Second Quarter. The Detection Systems, IMC, Wolf Coach and Avionics Systems acquired businesses contributed $67.6 million of the increase in sales. Excluding these acquisitions, sales declined $13.2 million, or 14.4%, primarily because of lower volumes for commercial aviation products and commercial communication products. The decreases include $16.3 million for commercial aviation products and commercial communication products, including technical support services, and $4.4 million for microwave components. These declines were partially offset by increases of $4.7 million for Flyaway Triband Satellite Terminals (FTSATs) and $2.8 million for commercial maritime products.

Consolidated costs and expenses increased $240.6 million to $1,098.1 million for the 2003 Second Quarter from $857.5 million for the 2002 Second Quarter, primarily as a result of the increase in sales.

Costs and expenses for "Contracts, primarily U.S. Government" increased $194.6 million to $955.4 million for the 2003 Second Quarter from $760.8 million for the 2002 Second Quarter. Approximately 53% of the increase is attributable to our acquired businesses. The remaining increase is primarily attributed to sales growth for ISR and secure communications systems and products, aircraft modernization, communications software and engineering support services and naval power equipment. These increases were partially offset by declines for training devices, fuzing products and acoustic undersea warfare products due to lower volume. Costs and expenses for sales on our direct and indirect contracts with the U.S. Government include selling, general and administrative (SG&A) costs, including independent research and development and bid and proposal costs, because SG&A costs are allowable, indirect contract costs that we allocate to our U.S. Government contracts in accordance with U.S. Government regulations. Accordingly, we do not report SG&A costs on U.S. Government contracts as period expenses. SG&A costs allocated to our U.S. Government contracts were $123.5 million for the 2003 Second Quarter and $106.2 million for the 2002 Second Quarter (see Note 5 to our unaudited condensed consolidated financial statements).

Costs and expenses for "Commercial, primarily products" increased $46.0 million to $142.7 million for the 2003 Second Quarter from $96.7 million for the 2002 Second Quarter. The increase was primarily due to increased sales attributable to our acquired businesses, which was partially offset by cost and expense reductions at PrimeWave and lower expenses for commercial aviation products, commercial communication products and microwave components products due to lower sales volume. SG&A expenses increased $12.6 million to $41.2 million for the 2003 Second Quarter from $28.6 million for the 2002 Second Quarter. The increase was due to expenses incurred by our acquired businesses, which were partially offset by lower SG&A expenses at PrimeWave, and our commercial communication products businesses arising from cost and expense reductions. Research and development (R&D) expenses increased $1.9 million to $9.6 million for the 2003 Second Quarter from $7.7 million for the 2002 Second Quarter. The increase was primarily due to the Detection Systems acquired business, which was included in our results of operations for the entire 2003 Second Quarter but only beginning on June 14, 2002 for the 2002 Second Quarter, partially offset by lower R&D expenses for PrimeWave because of cost and expense reductions.

Consolidated operating income increased by $31.1 million to $128.8 million for the 2003 Second Quarter from $97.7 million for the 2002 Second Quarter. The increase was primarily due to higher sales from all of our segments and cost and expense reductions at PrimeWave. Consolidated operating income as a percentage of sales (operating margin) increased by 0.3 percentage points to 10.5% for the 2003 Second Quarter from 10.2% for the 2002 Second Quarter. The increase in operating margin was due to higher margins for the Secure Communications & ISR, Training, Simulation & Support Services and

29

Specialized Products segments, which were partially offset by lower margins for the Aviation Products & Aircraft Modernization segment. The changes in the operating margins for our segments are discussed below.

Operating income for "Contracts, primarily U.S Government" increased $22.7 million to $125.7 million for the 2003 Second Quarter from $103.0 million for the 2002 Second Quarter. Operating margin declined 0.3 percentage points to 11.6% for the 2003 Second Quarter from 11.9% for the 2002 Second Quarter. The operating margin decline was primarily because of lower margins from acquired businesses. Additionally, the losses for our naval power equipment businesses declined sequentially to $3.1 million for the 2003 Second Quarter from $7.3 million for the 2003 first quarter as production levels continued to increase, resulting in higher shipments.

Operating income for "Commercial, primarily products" increased $8.4 million to $3.1 million for the 2003 Second Quarter from a loss of $5.3 million for the 2002 Second Quarter. Operating margin improved 7.9 percentage points to 2.1% for the 2003 Second Quarter from a negative margin of 5.8% for the 2002 Second Quarter. The improvement was primarily related to the Avionics System business acquired from Goodrich Corporation, and to cost and expense reductions at PrimeWave. These increases were partially offset by lower margins on commercial aviation products due to lower sales volume.

Interest expense increased $2.1 million to $33.7 million for the 2003 Second Quarter from $31.6 million for the 2002 Second Quarter because savings from the interest rate swap agreements decreased from $3.7 million for the 2002 Second Quarter to $2.0 million for the 2003 Second Quarter. The remaining increase was due to higher fees on unused revolver balances.

Interest and other income (expense) decreased $0.1 million to a $0.1 million expense in the 2003 Second Quarter from a $0.2 million expense in the 2002 Second Quarter. The decrease in the expense was due to higher interest income earned because of higher average cash and cash equivalents balances partially offset by higher losses on equity method investments during the 2003 Second Quarter compared to the 2002 Second Quarter. The 2003 Second Quarter includes a charge of $11.2 million ($7.2 million after-tax, or $0.07 per diluted share) for the early retirement in June 2003 of $180 million 8½% Senior Subordinated Notes due 2008. These notes were refinanced with a portion of the net proceeds from the $400 million 6 1/8% Senior Subordinated Notes due 2013 issued in May 2003. See "Liquidity and Capital Resources" below. The 2002 Second Quarter includes a charge of $16.2 million ($9.9 million after-tax, or $0.11 per diluted share) for the early retirement in June 2002 of $225 million 10 3/8 % Senior Subordinated Notes due 2007. These notes were refinanced with a portion of the net proceeds from the $750 million 7 5/8% Senior Subordinated Notes due 2012 issued in June 2002. In accordance with Statement of Financial Accounting Standards (SFAS) No. 145, the 2002 Second Quarter debt retirement charge, which was classified as an extraordinary item in the prior year presentation has been reclassified as a component of income from continuing operations along with the 2003 Second Quarter debt retirement charge.

Minority interest decreased $1.4 million to $0.4 million for the 2003 Second Quarter from $1.8 million for the 2002 Second Quarter because of a decrease in the operating income for Aviation Communication & Surveillance Systems, LLC (ACSS) due to the continued weakness in the commercial aviation market.

The income tax provision for the 2003 Second Quarter is based on the estimated effective income tax rate for 2003 of 36.0%, compared with the effective income tax rate of 34.0% for the 2002 Second Quarter.

Basic earnings per share (EPS) increased $0.16 to $0.56 for the 2003 Second Quarter from $0.40 for the 2002 Second Quarter. Diluted EPS increased $0.15 to $0.53 for the 2003 Second Quarter from $0.38 for the 2002 Second Quarter. Excluding the debt retirement charges, discussed above, in both periods, diluted earnings per share for the 2003 Second Quarter increased 22.4% to $0.60 from $0.49 for the 2002 Second Quarter. We have provided this supplemental measurement of "diluted EPS excluding debt retirement charges" because the debt retirement charges represent incremental costs and expenses arising from the early redemption of the respective senior subordinated notes and are not related to the on-going operations of L-3. In addition, management in evaluating the performance of its businesses considers, among other financial measures, "diluted EPS excluding debt retirement charges" and believes such measure provides useful information to investors.

30

Diluted weighted-average common shares outstanding increased 16.4% to 105.6 million for the 2003 Second Quarter from 90.7 million for the 2002 Second Quarter. The increase is due to additional shares outstanding from the sale of 14.0 million shares of our common stock on June 28, 2002.

The 2003 and 2002 Second Quarters diluted EPS computation did not include the effect of the 7.8 million shares of L-3 Holdings common stock that are issuable upon conversion of the CODES because the conditions required for the CODES to become convertible were not satisfied. However, if the CODES had been convertible, diluted EPS would have decreased $0.01 for the 2003 Second Quarter and diluted EPS for the 2002 Second Quarter would have remained unchanged.

Secure Communications & ISR

Sales within our Secure Communications & ISR segment increased $71.4 million, or 25.4%, to $352.6 million for the 2003 Second Quarter from $281.2 million for the 2002 Second Quarter. Excluding the increase in sales from the ComCept and Aeromet acquired businesses of $6.9 million, sales grew $64.5 million, or 22.9%. This increase was primarily due to continued strong demand from the DoD and other U.S. Government agencies for the Company's secure communications and ISR systems and products.

Operating income increased by $12.8 million to $42.5 million for the 2003 Second Quarter from $29.7 million for the 2002 Second Quarter because of higher sales and operating margin. Operating margin increased to 12.1% for the 2003 Second Quarter from 10.6% for the 2002 Second Quarter because of higher sales volume for defense systems and cost improvements.

Training, Simulation & Support Services

Sales within our Training, Simulation & Support Services segment increased $53.6 million, or 27.2%, to $250.8 million for the 2003 Second Quarter from $197.2 million for the 2002 Second Quarter. The increase in sales from the Telos, TMA and Ship Analytics acquired businesses was $27.7 million. Excluding the increase in sales from these acquisitions, sales increased $25.9 million, or 13.1%. This increase was due to increases in sales for communications software support and engineering support services and training services.

Operating income increased by $6.9 million to $29.2 million for the 2003 Second Quarter from $22.3 million for the 2002 Second Quarter because of higher sales and operating margin. Operating margin increased 0.3 percentage points to 11.6% for the 2003 Second Quarter from 11.3% for the 2002 Second Quarter. Higher sales from communications software support services and training services increased operating margin by 1.3 percentage points. Acquired businesses increased operating margin by 0.7 percentage points. These increases were partially offset by a decrease of 1.7 percentage points primarily due to lower margins for engineering support services.

Aviation Products & Aircraft Modernization

Sales within our Aviation Products & Aircraft Modernization segment increased $53.2 million, or 26.5%, to $253.7 million for the 2003 Second Quarter from $200.5 million for the 2002 Second Quarter. The increase in sales from the Avionics Systems acquired business was $27.6 million. Excluding this acquisition, sales increased $25.6 million, or 12.8%. The increase was primarily due to $36.9 million for aircraft modernization including those to the U.S. Special Operations Command (USSOCOM) related to the Iraq war activities and upgrades on C-130 aircraft for Greece and Malaysia. Additionally, volume increased $2.8 million for commercial maritime products, including $0.6 million for the recently introduced Automated Identification System (AIS) product, for which the development was completed and the certification substantially completed in the 2003 Second Quarter. We expect AIS sales to increase in the second half of 2003. The sales increases for aircraft modernization and commercial maritime products were partially offset by a decline of $10.8 million for commercial aviation products caused by the continued weakness in the commercial aviation markets and $3.3 million primarily for display systems due to the timing of contractual shipments.

Operating income increased by $1.5 million to $33.7 million for the 2003 Second Quarter from $32.2 million for the 2002 Second Quarter because of higher sales, which were partially offset by lower

31

operating margin. Operating margin declined 2.8 percentage points to 13.3% for the 2003 Second Quarter from 16.1% for the 2002 Second Quarter primarily because of volume declines for commercial aviation products. These decreases were partially offset by the Avionics Systems acquired business which has higher margins than the other businesses in the segment and increased margins by 0.7 percentage points.

Specialized Products

Sales within our Specialized Products segment increased $93.5 million, or 33.8%, to $369.8 million for the 2003 Second Quarter from $276.3 million for the 2002 Second Quarter. The increase in sales was principally attributable to $120.6 million from the Detection Systems, Ruggedized Command & Control, Electron Devices, Wolf Coach, IMC, Westwood and Wescam acquired businesses. Excluding these acquisitions, sales declined $27.1 million, or 9.8%. Volume declined $23.4 million for fuzing products, acoustic undersea warfare products and training devices because of certain contracts approaching their scheduled completion and the timing of sales on orders and contracts awarded during the 2003 First Half that will be recognized to revenue beginning in the second half of 2003 and continuing through 2004. Volume declined $12.2 million primarily for telemetry, space and navigation products and microwave components due to continued weakness in those commercial markets. Sales of EDS systems declined $5.6 million to $12.4 million for the 2003 Second Quarter. Sales of naval power equipment increased by $9.4 million because of increasing shipments, and sales of FTSATs increased $4.7 million because of strong demand from the U.S. military. We expect sales of EDS systems for 2003 to decline to approximately $130 million from $339 million for 2002, with most of the decline occurring in the 2003 fourth quarter because sales of EDS systems were $256 million in the 2002 fourth quarter. Our previous estimate of $175 million for 2003 sales of EDS systems has been reduced by $45 million because of changes in the fiscal 2003 spending priorities of the U.S. Transportation Security Administration (TSA).

Operating income increased by $9.9 million to $23.4 million for the 2003 Second Quarter from $13.5 million for the 2002 Second Quarter because of higher sales and operating margin. Operating margin increased 1.4 percentage points to 6.3% for the 2003 Second Quarter from 4.9% for the 2002 Second Quarter. Sale price and cost improvements on security products and training devices increased operating margin by 3.0 percentage points. This increase was partially offset by a decline of 1.6 percentage points primarily because of sales declines for telemetry, space and navigation products, fuzing products and microwave components.

Consolidated sales increased $663.9 million to $2,315.9 million for the 2003 First Half from sales of $1,652.0 million for the 2002 First Half. Sales grew $158.2 million, or 9.6%, excluding the increase in sales from acquired businesses of $505.7 million discussed below.

Sales from "Contracts, primarily U.S. Government" increased $563.5 million to $2,045.9 million for the 2003 First Half from $1,482.4 million for the 2002 First Half. The IS, Telos, ComCept, TMA, Electron Devices, Ruggedized Command & Control, Westwood, Wescam, Ship Analytics and Aeromet acquired businesses contributed $385.8 million of the increase in sales. Excluding these acquisitions, sales grew $177.7 million, or 12.0%, primarily because of higher sales volume in our defense businesses. The increases include $121.7 million for secure communications and ISR systems and products, $48.2 million for aircraft modernization, $29.2 million for communications software and engineering support services, $19.6 million for security products, $19.4 million for naval power equipment and $2.5 million for training services. These increases were partially offset by volume declines of $29.1 million for fuzing products, $9.8 million for acoustic undersea warfare products, $7.2 million for training devices, $2.5 million for display systems and $14.3 million primarily for telemetry, space and navigation products.

33

Sales from "Commercial, primarily products" increased $100.4 million to $270.0 million for the 2003 First Half from $169.6 million for the 2002 First Half. The Detection Systems, IMC, Wolf Coach and Avionics Systems acquired businesses contributed $119.9 million of the increase in sales. Excluding these acquisitions, sales declined $19.5 million, or 11.5%. This decrease in sales was due to volume declines of $22.9 million for commercial aviation and commercial communication products, including technical support services and $9.6 million for microwave components. These declines were partially offset by increases of $8.1 million for FTSATs and $4.9 million for commercial maritime products.

Consolidated costs and expenses increased $595.3 million to $2,078.3 million for the 2003 First Half from $1,483.0 million for the 2002 First Half, primarily as a result of the increase in sales.

Costs and expenses for "Contracts, primarily U.S. Government" increased $506.6 million to $1,814.0 million for the 2003 First Half from $1,307.4 million for the 2002 First Half. Approximately 68% of the increase is attributable to our acquired businesses. The remaining increase is primarily attributed to sales growth for secure communications and ISR systems and products, communications software and engineering support services, aircraft modernization, naval power equipment and security products. These increases were partially offset by declines for fuzing products, training devices and acoustic undersea warfare products due to lower volume. SG&A costs allocated to our U.S. Government contracts were $239.9 million for the 2003 First Half and $190.3 million for the 2002 First Half (see Note 5 to our unaudited condensed consolidated financial statements).

Costs and expenses for "Commercial, primarily products" increased $88.7 million to $264.3 million for the 2003 First Half from $175.6 million for the 2002 First Half. The increase was primarily due to increased sales attributable to our acquired businesses, which was partially offset by cost and expense reductions at PrimeWave and lower expenses for commercial aviation products, commercial communication products and microwave components due to lower sales volume. SG&A expenses, increased $18.9 million to $73.0 million for the 2003 First Half from $54.1 million for the 2002 First Half. The increase was due to expenses incurred by our acquired businesses, which were partially offset by lower SG&A expenses at PrimeWave and our commercial communications products businesses arising from cost and expense reductions. R&D expenses increased $0.8 million to $18.4 million for the 2003 First Half from $17.6 million for the 2002 First Half. The increase was primarily due to the Detection Systems acquired business partially offset by lower R&D expenses incurred by ACSS, because the development of our new T²CAS product was substantially completed in 2002, and at PrimeWave because of cost and expense reductions.

Consolidated operating income increased by $68.6 million to $237.6 million for the 2003 First Half from $169.0 million for the 2002 First Half. The increase was primarily due to higher sales from all of our segments. Consolidated operating margin increased slightly by 0.1 percentage point to 10.3% for the 2003 First Half from 10.2% for the 2002 First Half. The increase in operating margin was due to higher margins for the Secure Communications & ISR, Training, Simulation & Support Services and Specialized Products segments, which were partially offset by lower margins for the Aviation Products & Aircraft Modernization segment. The changes in the operating margins for our segments are discussed below.

Operating income for "Contracts, primarily U.S. Government" increased $56.9 million to $231.9 million for the 2003 First Half from $175.0 million for the 2002 First Half. Operating margin declined 0.5 percentage points to 11.3% for the 2003 First Half from 11.8% for the 2002 First Half. The operating margin decline was primarily because of lower margins from acquired businesses.

Operating income for "Commercial, primarily products" increased $11.7 million to $5.7 million for the 2003 First Half from an operating loss of $6.0 million for the 2002 First Half. Operating margin improved 5.6 percentage points to 2.1% for the 2003 First Half from a negative margin of 3.5% for the 2002 First Half. The improvement was primarily due to lower losses from certain commercial businesses arising from cost and expense reductions and higher margins from the Avionics Systems business acquired from Goodrich Corporation.

Interest expense increased $8.2 million to $65.9 million for the 2003 First Half from $57.7 million for the 2002 First Half. The increase is attributable to the higher average outstanding debt during the 2003 First Half, lower savings from the interest rate swap agreements of $2.6 million and higher fees on unused revolver balances. The 2003 First Quarter also included $0.4 million of accrued contingent interest expense on the CODES.

34

Interest and other income increased $0.5 million to $1.3 million in the 2003 First Half from $0.8 million in the 2002 First Half. The increase is due to the reduction in the liability that represents the fair value assigned to the embedded derivatives related to the CODES, partially offset by higher losses on equity method investments during the 2003 First Half compared to the 2002 First Half. The 2003 First Half includes a charge of $11.2 million ($7.2 million after-tax, or $0.07 per diluted share) for the early retirement in June of 2003 of $180 million 8½% Senior Subordinated Notes due 2008 as previously discussed. See "Liquidity and Capital Resources" below. The 2002 First Half includes a charge of $16.2 million ($9.9 million after-tax, or $0.11 per diluted share) for the early retirement in June 2002 of $225 million 10 3/8% Senior Subordinated Notes due 2007 as previously discussed. In accordance with SFAS No. 145, the 2002 First Half debt retirement charge, which was classified as an extraordinary item in the prior year presentation, has been reclassified as a component of income from continuing operations along with the 2003 First Half debt retirement charge.

Minority interest decreased $2.1 million to $0.7 million for the 2003 First Half from $2.8 million for the 2002 First Half because of a decrease in the operating income for ACSS due to the continued weakness in the commercial aviation market.

The income tax provision for the 2003 First Half is based on the estimated effective income tax rate for 2003 of 36.0%, compared with the effective income tax rate of 34.6% for the 2002 First Half.

Basic EPS before cumulative effect of a change in accounting principle increased $0.31 to $1.08 for the 2003 First Half from $0.77 for the 2002 First Half. Diluted EPS before cumulative effect of a change in accounting principle increased $0.30 to $1.03 for the 2003 First Half from $0.73 for the 2002 First Half. Net income for the 2002 First Half includes a charge, net of income taxes, of $24.4 million ($0.31 per basic share and $0.27 per diluted share) for the cumulative effect of a change in accounting principle for goodwill impairment in connection with the adoption of SFAS No. 142. Including the effect of a change in accounting principle, basic and diluted EPS for 2002 First Half was $0.46. Excluding the debt retirement charges, discussed above, in both periods, diluted earnings per share for the 2003 First Half increased 31.0% to $1.10 from $0.84 for the 2002 First Half.

Diluted weighted-average common shares outstanding increased 16.9% to 105.3 million for the 2003 First Half from 90.1 million for the 2002 First Half. The increase principally reflects the additional shares outstanding from the sale of 14.0 million shares of our common stock on June 28, 2002.

The 2003 and 2002 First Half diluted EPS computation did not include the effect of the 7.8 million shares of L-3 Holdings common stock that are issuable upon conversion of the CODES because the conditions required for the CODES to become convertible were not satisfied. However, if the CODES had been convertible, diluted EPS would have decreased by approximately $0.02 for the 2003 First Half and diluted EPS before cumulative effect of a change in accounting principle for the 2002 First Half would have remained unchanged.

Secure Communications & ISR

Sales within our Secure Communications & ISR segment increased $240.3 million, or 54.6%, to $680.3 million for the 2003 First Half from $440.0 million for the 2002 First Half. Excluding the increase in sales from the IS, ComCept and Aeromet acquired businesses of $117.2 million, sales increased $123.1 million, or 28.0%. This increase was primarily due to continued strong demand from the DoD and other U.S. Government agencies for the Company's secure communications and ISR systems and products.

Operating income increased by $28.8 million to $74.9 million for the 2003 First Half from $46.1 million for the 2002 First Half because of higher sales and operating margin. Operating margin increased to 11.0% for the 2003 First Half from 10.5% for the 2002 First Half because of higher sales volume for defense systems and cost improvements.

Training, Simulation & Support Services

Sales within our Training, Simulation & Support Services segment increased $90.2 million, or 23.0%, to $482.2 million for the 2003 First Half from $392.0 million for the 2002 First Half. The increase in sales from the Telos, TMA and Ship Analytics acquired businesses was $63.9 million. Excluding the increase

35

in sales from acquisitions, sales increased $26.3 million, or 6.7%. This increase was primarily due to increases in sales for communications software and engineering support services and training services partially offset by commercial technical support services.

Operating income increased by $13.9 million to $57.7 million for the 2003 First Half from $43.8 million for the 2002 First Half because of higher sales and operating margin. Operating margin increased 0.8 percentage points to 12.0% for the 2003 First Half from 11.2% for the 2002 First Half. Acquired businesses increased operating margin by 0.5 percentage points. The remaining increase was primarily due to higher sales and cost and expense reductions for communications software support services and training services.

Aviation Products & Aircraft Modernization

Sales within our Aviation Products & Aircraft Modernization segment increased $99.7 million, or 32.5%, to $406.1 million for the 2003 First Half from $306.4 million for the 2002 First Half. The increase in sales from the IS and Avionics Systems acquired businesses was $65.4 million. Excluding the increase in sales from these acquisitions, sales increased $34.3 million, or 11.2%. The increase was primarily due to $48.2 million for aircraft modernization including those to the U.S. Special Operations Command (USSOCOM) related to the Iraq war activities and upgrades on C-130 aircraft for Greece and Malaysia. Additionally, volume increased $4.9 million for commercial maritime products, including $0.6 million for the recently introduced AIS product discussed above. These increases were partially offset by a decline of $16.3 million primarily for commercial aviation products caused by the continued weakness in the commercial aviation markets and $2.5 million for display systems due to the timing of contractual shipments.

Operating income increased by $4.8 million to $54.5 million for the 2003 First Half from $49.7 million for the 2002 First Half because of higher sales, which were partially offset by lower operating margin. Operating margin declined 2.8 percentage points to 13.4% for the 2003 First Half from 16.2% for the 2002 First Half primarily because of volume declines for commercial aviation products. These decreases were partially offset by the Avionics Systems acquired business which has higher margins than the other businesses in the segment and increased margins by 0.4 percentage points.

Specialized Products

Sales within our Specialized Products segment increased $233.7 million, or 45.5%, to $747.3 million for the 2003 First Half from $513.6 million for the 2002 First Half. The increase from the Detection Systems, Ruggedized Command & Control, Electron Devices, Wolf Coach, IMC, Westwood and Wescam acquired businesses was $259.2 million. Excluding these acquisitions, sales decreased $25.5 million, or 5.0%. Volume declined $46.1 million for fuzing products, acoustic undersea warfare products and training devices because of certain contracts approaching their scheduled completion and the timing of sales on orders and contracts awarded during the 2003 First Half that will be recognized to revenue beginning in the second half of 2003 and continuing through 2004. Volume declined $26.5 million primarily for telemetry, space and navigation products and microwave components due to continued weakness in those commercial markets. Sales of EDS systems increased $19.6 million. Sales of naval power equipment increased by $19.4 million because of increasing shipments and sales of FTSATs increased $8.1 million because of strong demand from the U.S. military. Although our EDS Systems sales increased for the 2003 First Half compared to the 2002 First Half, we expect sales of EDS systems to decline for the full year 2003 compared to 2002 as discussed above.

Operating income increased by $21.1 million to $50.5 million for the 2003 First Half from $29.4 million for the 2002 First Half because of higher sales and operating margin. Operating margin increased 1.1 percentage points to 6.8% for the 2003 First Half from 5.7% for the 2002 First Half. Higher volumes and operating margins for security products increased operating margin by 1.0 percentage points. Acquired businesses increased operating margin by 0.5 percentage points. Operating margin declined by 0.4 percentage points because of sales declines for telemetry, space and navigation products, fuzing products and microwave components.

Balance Sheet

Contracts in process increased $100.2 million from December 31, 2002 to June 30, 2003. The increase included $23.8 million related to acquired businesses and $76.4 million principally from:

•

increases of $36.4 million in unbilled contract receivables, net of unliquidated progress payments, due to sales for aircraft modernization, secure communications systems and products and engineering support services partially offset by higher billings and collections for security products and receipt of unliquidated progress payments for ISR systems and products and deliveries for acoustic undersea warfare products;

•

increases of $32.9 million in inventoried contract costs, primarily for security products and acoustic undersea warfare products;

•

increases of $19.8 million in inventories at lower of cost or market due to increases for security products and commercial aviation products; and

•

decreases of $12.7 million in billed receivables because of higher collections from security products, aircraft modernization and secure communications and ISR systems and products, partially offset by billed receivables due to higher billings for training devices and motion simulators and higher sales from engineering support services.

Billed receivables, including acquisitions, increased by $11.1 million to $579.5 million at June 30, 2003, from $568.4 million at December 31, 2002. Billed receivables for our U.S. Government contractor businesses increased by $19.7 million from $450.9 million at December 31, 2002 to $470.6 million at June 30, 2003 primarily due to higher billings for training devices and motion simulators. Billed receivables for our commercial businesses decreased by $8.6 million from $117.5 million at December 31, 2002 to $108.9 million at June 30, 2003 due to higher collections from security products.

L-3's days sales outstanding (DSO) declined to 67.3 at June 30, 2003 from 68.9 at December 31, 2002, primarily because of the timing of certain receivable collections, which occurred sooner than we expected. We calculate our DSO by dividing (a) our aggregate billed receivables and net unbilled contract receivables at the end of the period, by (b) our sales for the last twelve-month period adjusted on a pro forma basis to include sales from acquired businesses for the entire twelve-month period, divided by 365.

Included in contracts in process at June 30, 2003, are net billed receivables of $10.6 million and net inventories of $16.4 million related to our PrimeWave business. At December 31, 2002, we had $11.4 million of net billed receivables and $18.2 million of net inventories related to our PrimeWave business.

The increase in property, plant and equipment (PP&E) during the 2003 First Half was principally related to the acquisition of Avionics Systems. The percentage of depreciation expense to average gross PP&E declined to 6.0% for the 2003 First Half from 6.5% for the 2002 First Half. The decline was attributable to fully depreciated PP&E used in certain of our operations despite having net carrying amounts of zero (after accumulated depreciation) and which are not removed from the balance sheet until they are retired or otherwise disposed of.

Goodwill increased $204.8 million to $2,999.3 million at June 30, 2003 from $2,794.5 million at December 31, 2002. The increase was principally due to the Avionics Systems and Aeromet Inc. acquired businesses as well as purchase price adjustments based on the closing date balance sheets, payments of resolved contingent purchase price adjustments (earnouts) and revised estimates of preliminary fair values of acquired assets and liabilities for certain acquisitions completed prior to January 1, 2003.

The increase in accounts payable was due to the timing of payments as well as the Avionics Systems acquisition completed in March of 2003. The increase in accrued employment costs was primarily due to the Avionics Systems acquisition. The increase in other current liabilities was primarily due to an increase in billings in excess of costs incurred for training devices and naval power equipment, related to amounts collected from customers in excess of incurred costs for the completion of performance milestones on certain contracts in process. The increase in pension and postretirement liabilities was primarily due to the timing of contributions and funding of payments.

37

Customer advances decreased by $13.1 million because liquidations exceeded collections, primarily related to shipments and performance on contracts with foreign customers for acoustic undersea warfare products and aircraft modernization. The timing of collections and liquidation of customer advances are prescribed by contract terms, and generally do not coincide because collections mostly occur upon the award of a contract and during the earlier periods of performance, and conversely, liquidations mostly occur during later periods of performance as products are delivered and other work items are completed. Additionally, customer advances do not affect or determine the recognition of revenue because customer advances are a contract financing method.

Statement of Cash Flows

Six Months Ended June 30, 2003 Compared with Six Months Ended June 30, 2002

Cash increased to $306.8 million at June 30, 2003 from $134.9 million at December 31, 2002. The table below provides a summary of our cash flows for the periods indicated.

				Six Months Ended June 30,
				2003				2002
				(in millions)
Net cash from operating activities				$	208.3			$	112.8
Net cash used in investing activities					(257.1	)			(1,338.8	)
Net cash from financing activities					220.7				1,331.1
Net increase in cash				$	171.9			$	105.1

Operating Activities

We generated $208.3 million of cash from operating activities during the 2003 First Half, an increase of $95.5 million from the $112.8 million generated during the 2002 First Half. Net income adjusted for non-cash expenses and deferred income taxes increased $66.3 million to $222.8 million for the 2003 First Half from $156.5 million for the 2002 First Half. Deferred income taxes increased primarily because of larger estimated tax deductions arising from our recent acquisitions. Other non-cash expenses consist primarily of contributions of L-3 Holdings' common stock to employee savings plans and depreciation and amortization. The use of cash from the change in operating assets and liabilities for the 2003 First Half decreased to $14.5 million, compared to $43.7 million for the 2002 First Half, primarily because of lower levels of contracts in process (excluding acquired amounts), including the collection of certain receivables sooner than we expected, and, an increase in collections of billings in excess of incurred costs on contracts in process. Additionally, the use of cash for other current assets was primarily due to higher insurance premiums paid during the 2003 First Half due to acquired businesses. These prepaid insurance premiums will be expensed during the second half of 2002. Liquidations exceeded collections for customer advances. The increase in accounts payable was due to the timing of payments. The source of cash for other current liabilities was primarily due to an increase in billings in excess of costs incurred on contracts for training devices and naval power equipment. The source of cash from the change in pension and postretirement benefits was due to pension and postretirement expenses for the 2003 First Half exceeding related cash contributions. The source of cash in other liabilities was primarily due to the non-current portion of deferred gains amounting to $10.7 million recorded for the termination of our interest rate swap agreements, discussed below.

We expect to generate net cash from operating activities of approximately $413 million for the full year 2003. We expect that our cash interest payments for the third quarter of 2003 will be less than those for the 2003 Second Quarter by approximately $24 million. Our cash interest payments, which are based on the fixed rate coupons and the interest payment dates of our debt, were approximately $18 million for the 2003 First Quarter, approximately $45 million for the 2003 Second Quarter, and are expected to be approximately $21 million for the third quarter of 2003, and approximately $37 million for the fourth quarter of 2003 after giving effect to the offering by L-3 Communications of $400 million of 6 1/8% Senior Subordinated Notes and the redemption of the 8½% Senior Subordinated Notes (see Financing Activities below).

38

Investing Activities

During the 2003 First Half, we invested $219.9 million to acquire Avionics Systems and Aeromet Inc. and to pay for acquisition costs, purchase price adjustments based on the closing date balance sheets and resolved contingent purchase price adjustments based on financial performance achieved for certain acquisitions completed prior to January 1, 2003. During the 2002 First Half, we invested $1,316.1 million to acquire businesses, primarily Integrated Systems and the Detection Systems business of PerkinElmer, Inc.

We make capital expenditures for the improvement of manufacturing facilities and equipment. We expect to use approximately $100 million of cash for capital expenditures, and to receive net cash proceeds of approximately $2 million from the dispositions of property, plant and equipment for the full year of 2003.

Financing Activities

On May 21, 2003, L-3 Communications sold $400.0 million of 6 1/8% Senior Subordinated Notes due July 15, 2013 (May 2003 Notes) at a discount of $1.8 million or $398.2 million. Interest is payable semi-annually on January 15 and July 15 of each year commencing July 15, 2003. The net cash proceeds from this offering amounted to approximately $391.0 million after deducting the discounts, commissions and other offering expenses. The net proceeds from this offering were used to redeem the 8½% Senior Subordinated Notes due 2008 and increase cash and cash equivalents.

On May 21, 2003, we initiated a full redemption of all the outstanding $180.0 million aggregate principal amount of 8½% Senior Subordinated Notes due 2008 (May 1998 Notes). On June 20, 2003, we purchased and paid cash for all the outstanding May 1998 Notes, including accrued interest. For the six months ended June 30, 2003, we recorded a pre-tax charge of $11.2 million, comprising of premiums and other transaction costs of $7.8 million and $3.4 million to write-off the unamortized balance of debt issue costs and the deferred loss on the terminated interest rate swap agreements related to the May 1998 Notes.

At June 30, 2003, available borrowings under our senior credit facilities were $669.4 million, after reductions for outstanding letters of credit of $80.6 million. There were no outstanding borrowings under our senior credit facilities at June 30, 2003.

In January of 2003, we entered into interest rate swap agreements on $200.0 million of our 7 5/8% Senior Subordinated Notes due 2012. These swap agreements exchanged the fixed interest rate for a variable interest rate on $200.0 million of the $750.0 million principal amount outstanding. In March of 2003, we terminated these interest rate swap agreements and received cash proceeds of $6.4 million. Prior to the termination of the swap agreements, we recorded a reduction to interest expense for the 2003 First Half of $1.2 million. This reduction represented interest savings earned for the period prior to the termination of these swap agreements. The average variable interest rate that we paid under the swap agreements was 4.0% compared to the 7 5/8% fixed interest rate on the notes subject to the swaps. The remaining $5.2 million of the proceeds represented the future value of the swap agreements at the termination date and was recorded as a deferred gain. The deferred gain is being amortized as a reduction to interest expense over the remaining term of the 7 5/8% Senior Subordinated Notes due 2012 at an amount of $0.1 million per quarter, or $0.6 million annually.

In March of 2003, we entered into interest rate swap agreements on $200.0 million of our 7 5/8% Senior Subordinated Notes due 2012. These swap agreements exchanged the fixed interest rate for a variable interest rate on $200.0 million of the $750.0 million principal amount outstanding. In June of 2003, we terminated these interest rate swap agreements and received cash proceeds of $8.3 million. Prior to the termination of these swap agreements, we recorded a reduction to interest expense for the 2003 First Half of $1.6 million. This reduction represented interest savings earned for the period prior to the termination of these swap agreements. The average variable interest rate that we paid under the swap agreements was 4.4% compared to the 7 5/8% fixed interest rate on the notes subject to the swaps. The remaining $6.7 million of the proceeds represented the future value of the swap agreements at the termination date and was recorded as a deferred gain. The deferred gain is being amortized as a reduction to interest expense

over the remaining term of the 7 5/8% Senior Subordinated Notes due 2012 at an amount of $0.2 million per quarter, or $0.7 million annually.

The senior credit facilities, senior subordinated notes, Convertible Notes and CODES agreements contain financial covenants and other restrictive covenants which remain in effect so long as we owe any amount or any commitment to lend exists thereunder. We are in compliance with those covenants in all material respects. The borrowings under the senior credit facilities are guaranteed by L-3 Holdings and by substantially all of the material domestic subsidiaries of L-3 Communications on a senior basis. The payments of principal and premium, if any, and interest on the senior subordinated notes are unconditionally guaranteed, on an unsecured senior subordinated basis, jointly and severally, by all of L-3 Communications' restricted subsidiaries other than its foreign subsidiaries. The guarantees of the senior subordinated notes are junior to the guarantees of the senior credit facilities and rank pari passu with each other and the guarantees of the Convertible Notes and the CODES. The Convertible Notes and CODES are unconditionally guaranteed, on an unsecured senior subordinated basis, jointly and severally, by L-3 Communications and substantially all of its direct and indirect material domestic subsidiaries. These guarantees rank junior to the guarantees of the senior credit facilities and rank pari passu with each other and the guarantees of the senior subordinated notes. See Note 8 to our consolidated financial statements for fiscal year ended December 31, 2002, included in our Annual Report on Form 10-K filed on March 11, 2003, for a description of our debt and related financial covenants at December 31, 2002. Based upon our current level of operations, we believe that our cash from operating activities, together with available borrowings under the senior credit facilities, will be adequate to meet our anticipated requirements for working capital, capital expenditures, commitments, research and development expenditures, contingent purchase prices, program and other discretionary investments, and interest payments for the foreseeable future. There can be no assurance, however, that our business will continue to generate cash flow at current levels, or that currently anticipated improvements will be achieved. If we are unable to generate sufficient cash flow from operations to service our debt, we may be required to sell assets, reduce capital expenditures, refinance all or a portion of our existing debt or obtain additional financing. Our ability to make scheduled principal payments or to pay interest on or to refinance our indebtedness depends on our future performance and financial results, which, to a certain extent, are subject to general conditions in or affecting the defense industry and to general economic, political, financial, competitive, legislative and regulatory factors beyond our control. There can be no assurance that sufficient funds will be available to enable us to service our indebtedness, or make necessary capital expenditures or to make discretionary investments.

Contingencies

See Note 11 to the Unaudited Condensed Consolidated Financial Statements.

Recently Issued and Proposed Accounting Standards

In January of 2003, the FASB issued FASB Interpretation No. 46, Consolidation of Variable Interest Entities (FIN 46). This interpretation provides guidance on the identification of, and financial reporting for, entities over which control is achieved through means other than voting rights. Such entities have been termed by FIN 46 as variable interest entities (VIE). Once effective, FIN 46 will be the guidance that determines (1) whether consolidation is required under the "controlling financial interest" model of ARB Bulletin No. 51, Consolidated Financial Statements, or (2) whether the variable-interest model under FIN 46 should be used to account for existing and new entities. FIN 46 includes guidance for identifying the enterprise that will consolidate a VIE, which is the enterprise that is exposed to the majority of an entity's risks or receives the majority of the benefits from an entity's activities. FIN 46 also requires that the enterprises that hold a significant variable interest in a VIE make new disclosures in their financial statements. The transitional disclosures of FIN 46, which are effective immediately, require an enterprise to identify the entities in which it holds a variable interest, if the enterprise believes that those entities might be considered VIEs upon the adoption of FIN 46. The implementation and remaining disclosure requirements of FIN 46 are effective immediately for VIEs created after January 31, 2003, and on July 1, 2003 for all VIEs created before January 31, 2003. We do not hold any interests in VIEs that would require consolidation or additional disclosure.

40

In March of 2003, the Emerging Issues Task Force (EITF) issued EITF No. 00-21, Accounting for Revenue Arrangements with Multiple Deliverables. EITF No. 00-21 addresses how to determine whether a contractual arrangement involving multiple deliverables contains more than one accounting unit and how consideration should be measured and allocated to the separate accounting units. EITF No. 00-21 applies to all deliverables within contractually binding arrangements in all industries, except to the extent that a deliverable in a contractual arrangement is subject to other existing higher-level authoritative literature, and is effective for revenue arrangements entered into in fiscal periods beginning after June 15, 2003. We are currently evaluating the effect of EITF No. 00-21 on our revenue recognition accounting policies and on our consolidated results of operations and financial position.

In May 2003, the FASB issued SFAS No. 150, Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity. This Statement applies to certain financial instruments including mandatorily redeemable financial instruments that prior to SFAS No. 150 could have been accounted for as a component of equity. SFAS No. 150 requires that those instruments be classified as liabilities in statements of financial position. SFAS No. 150 also requires disclosures about alternative ways of settling the instruments and the capital structure of entities, whose shares are all mandatorily redeemable. SFAS No. 150 is effective for these financial instruments entered into or modified after May 31, 2003. For these financial instruments entered into before May 31, 2003, SFAS No. 150 is effective for our interim period beginning July 1, 2003. L-3 does not have any financial instruments that are within the scope of SFAS No. 150 and it is not expected to have a material effect on our consolidated results of operation or financial position.

Forward-Looking Statements

Certain of the matters discussed concerning our operations, cash flows, financial position, economic performance, and financial condition, including in particular, the likelihood of our success in developing and expanding our business and the realization of sales from backlog, include forward-looking statements within the meaning of section 27A of the Securities Act and Section 21E of the Exchange Act.

Statements that are predictive in nature, that depend upon or refer to events or conditions or that include words such as "expects," "anticipates," "intends," "plans," "believes," "estimates" and similar expressions are forward-looking statements. Although we believe that these statements are based upon reasonable assumptions, including projections of orders, sales, operating margins, earnings, cash flow, research and development costs, working capital, capital expenditures and other projections, they are subject to several risks and uncertainties, and therefore, we can give no assurance that these statements will be achieved. Such statements will also be influenced by factors such as:

•

our dependence on the defense industry and the business risks peculiar to that industry, including changing priorities or reductions in the U.S. Government defense budget;

•

our reliance on contracts with a limited number of agencies of, or contractors to, the U.S. Government and the possibility of termination of government contracts by unilateral government action or for failure to perform;

•

our ability to obtain future government contracts on a timely basis;

•

the availability of government funding and changes in customer requirements for our products and services;

•

our significant amount of debt and the restrictions contained in our debt agreements;

•

collective bargaining agreements and labor disputes;

•

the business and economic conditions in the markets we operate in, including those for the commercial aviation and communications markets;

•

economic conditions, competitive environment, international business and political conditions, timing of international awards and contracts;

•

our extensive use of fixed-price contracts as compared to cost-reimbursable contracts;

•

our ability to identify future acquisition candidates or to integrate acquired operations;

41

•

the rapid change of technology and high level of competition in the communication equipment industry;

•

our introduction of new products into commercial markets or our investments in commercial products or companies;

•

pension, environmental or legal matters or proceedings and various other market, competition and industryfactors, many of which are beyond our control; and

•

the fair values of our assets, including identifiable intangible assets and the estimated fair value of the goodwill balances for our reporting units which can be impaired or reduced by the other factors discussed above.

Readers of this document are cautioned that our forward-looking statements are not guarantees of future performance and the actual results or developments may differ materially from the expectations expressed in the forward-looking statements. As for the forward-looking statements that relate to future financial results and other projections, actual results will be different due to the inherent uncertainties of estimates, forecasts and projections and may be better or worse than projected. Given these uncertainties, you should not place any reliance on these forward-looking statements. These forward-looking statements also represent our estimates and assumptions only as of the date that they were made. We expressly disclaim a duty to provide updates to these forward-looking statements, and the estimates and assumptions associated with them, after the date of this filing to reflect events or changes or circumstances or changes in expectations or the occurrence of anticipated events.

ITEM 3.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

See Part II, Item 7, "Management's Discussion and Analysis of Results of Operations and Financial Condition — Liquidity and Capital Resources — Derivative Financial Instruments," of the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2002 for a discussion of the Company's exposure to market risks. The only substantial change in those risks during the six months ended June 30, 2003 is discussed below.

Derivative Financial Instruments

Interest Rate Risk.    Our financial instruments that are sensitive to changes in interest rates include borrowings under the senior credit facilities and interest rate swap agreements, all of which are denominated in U.S. dollars. The interest rates on the senior subordinated notes, Convertible Notes and CODES are fixed-rate and are not affected by changes in interest rates.

In January and March of 2003, we entered into new interest rate swap agreements on $200.0 million of our senior subordinated notes to convert their fixed interest rates to variable rates and to take advantage of the current low interest rate environment. These new swap agreements discussed above are described in "Management's Discussion and Analysis of Results of Operations and Financial Condition — Statement of Cash Flows — Financing Activities," of this Report. During the six-month period ended June 30, 2003, we terminated these interest rate swap agreements. At June 30, 2003, we do not have any outstanding interest rate swap agreements. These transactions are described in "Management's Discussion and Analysis of Results of Operations and Financial Condition — Statement of Cash Flows — Financing Activities section of this report.

ITEM 4.

CONTROLS AND PROCEDURES

The Company maintains disclosure controls and procedures that are designed to ensure that information required to be disclosed in the Company's reports under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms, and that such information is accumulated and communicated to the Company's management, including its Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures. Any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. The Company's management, with the participation of the Company's Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the design and operation of the Company's disclosure controls and procedures as of June 30, 2003. Based upon that evaluation and subject to the foregoing, the Company's Chief Executive Officer and Chief Financial Officer concluded that the design and operation of the Company's disclosure controls and procedures provided reasonable assurance that the disclosure controls and procedures are effective to accomplish their objectives.

In addition, there was no change in the Company's internal control over financial reporting that occurred during the quarter ended June 30, 2003 that has materially affected, or is reasonably likely to materially affect, the Company's internal control over financial reporting.

PART II – OTHER INFORMATION

ITEM 1.

LEGAL PROCEEDINGS

From time to time we are involved in legal proceedings arising in the ordinary course of our business. We believe that we are adequately reserved for these liabilities and that there is no litigation that could have a material adverse effect on our consolidated results of operations, financial condition or cash flows.

On August 6, 2002, Aviation Communications & Surveillance Systems, LLC (ACSS), a subsidiary of L-3 Communications Corporation, was sued by Honeywell International Inc. and Honeywell Intellectual Properties, Inc. (collectively, "Honeywell") for alleged infringement of patents that relate to terrain awareness avionics. The lawsuit was filed in the United States District Court for the District of Delaware. In December of 2002, Honeywell withdrew without prejudice the lawsuit against ACSS and agreed to proceed with non-binding arbitration. The arbitration was held during the week of July 28th, and the parties are awaiting the arbitrators decision, which will be delivered on August 22, 2003. If the matter is not resolved through arbitration, Honeywell may reinstitute the litigation after August 22, 2003. We had previously investigated the Honeywell patents and believe that ACSS has valid defenses against Honeywell's patent infringement suit. In addition, ACSS has been indemnified to a certain extent by Thales Avionics, which provided ACSS with the alleged infringing technology. Thales Avionics owns 30% of ACSS. In the opinion of management, the ultimate disposition of Honeywell's pending claim will not result in a material liability to us.

On November 18, 2002, we initiated a proceeding against OSI Systems, Inc. (OSI) in the United States District Court sitting in the Southern District of New York (the "New York action") seeking, among other things, a declaratory judgment that we had fulfilled all of our obligations under a letter of intent with OSI (the "OSI Letter of Intent"). Under the OSI Letter of Intent, we were to negotiate definitive agreements with OSI for the sale of certain businesses we acquired from PerkinElmer, Inc. on June 14, 2002. On December 23, 2002, OSI responded by filing suit against us in the United States District Court sitting in the Central District of California (the "California action") alleging, among other things, that we breached our obligations under the OSI Letter of Intent and seeking damages in excess of $100 million, not including punitive damages. On February 7, 2003, OSI filed an answer and counterclaims in the New York action that asserted substantially the same claims OSI had raised in the California action. The California action was dismissed by the California District Court in favor of the New York action. Under the OSI Letter of Intent, we proposed selling to OSI the conventional detection business and the ARGUS business that we recently acquired from PerkinElmer, Inc. Negotiations with OSI lasted for almost one year and ultimately broke down over issues regarding, among other things, intellectual property, product-line definitions, allocation of employees and due diligence. We believe that the claims asserted by OSI in its suit are without merit and intend to defend against the OSI claims vigorously.
