complex aerospace and electronic equipment, and to provide related engineering and technical services according to the buyer's specifications. These sales are transacted using written revenue arrangements or contracts, which are generally either fixed price, cost-reimbursable or time and material. These contracts are covered by the American Institute of Certified Public Accountants Statement of Position 81-1, Accounting for Performance of Construction-Type and Certain Production-Type Contracts (SOP 81-1) and Accounting Research Bulletin No. 45, Long-term Construction-Type Contracts (ARB 45). In addition, cost-reimbursable contracts are also specifically covered by Accounting Research Bulletin No. 43, Chapter 11, Section A, Government Contracts, Cost-Plus-Fixed Fee Contracts (ARB 43). Substantially all of our cost-reimbursable and time and material contracts are with the U.S. Government, primarily with the Department of Defense. Certain of our contracts with the U.S. Government are multi-year contracts that are funded annually by the customer, and sales on these multi-year contracts are based on amounts appropriated (funded) by the U.S. Government.

Sales and profits on fixed-price contracts are substantially recognized using percentage-of-completion methods of accounting. Sales and profits on fixed-price production contracts under which units are produced and delivered in a continuous or sequential process are recorded as units are delivered based on their contractual selling prices (the "units-of-delivery" method). Sales and profits on other fixed-price production contracts under which units are not produced and delivered in a continuous or sequential process or under which a relatively few number of units are produced are recorded based on the ratio of incurred costs to total estimated costs at completion of the contract (the "cost-to-cost" method). Under the percentage-of-completion methods of accounting, a single estimated total profit margin is used to recognize profit for each contract over its entire period of performance, which can exceed one year. Sales and profits on fixed-price contracts that require us to perform services that are not related to production of tangible assets are recognized in accordance with SAB No. 104, Revenue Recognition (SAB 104).

Accounting for the sales on a fixed-price contract requires the preparation of estimates of (1) the total contract revenue, (2) the total costs at completion, which is equal to the sum of the actual incurred costs to date on the contract and the estimated costs to complete the contract's statement of work, and (3) the measurement of progress towards completion. The estimated profit or loss at completion on a contract is equal to the difference between the total estimated contract revenue and the total estimated cost at completion. Under the units-of-delivery percentage-of-completion method, sales on a fixed-price contract are recorded as the units are delivered during the period at an amount equal to the contractual selling price of those units. Under the cost-to-cost percentage-of-completion method, sales on a fixed-price contract are recorded at amounts equal to the ratio of cumulative costs incurred and total estimated costs at completion, multiplied by (i) the total estimated contract revenue, less (ii) the cumulative sales recognized in prior periods. The profit recorded on a contract in any period using either the units-of-delivery method or cost-to-cost method is equal to (i) the current estimated total profit margin multiplied by the cumulative sales recognized, less (ii) the amount of cumulative profit previously recorded for the contract. In the case of a contract for which the total estimated costs exceed the total estimated revenues, a loss arises, and a provision for the entire loss is recorded in the period that it becomes evident. The unrecoverable costs on a loss contract that are expected to be incurred in future periods are recorded as a component of other current liabilities entitled "Estimated cost in excess of estimated contract value to complete contracts in process." Adjustments to original estimates for a contract's revenue, estimated costs at completion and estimated profit or loss are often required as work progresses under a contract, as experience is gained and as more information is obtained, even though the scope of work required under the contract may not change, or if contract modifications occur.

Sales on cost-reimbursable type contracts are recognized as allowable costs are incurred on the contract and become billable to the customer, at an amount equal to the allowable costs plus the estimated profit on those costs. The estimated profit on a cost-reimbursable contract is generally fixed or variable based on the contract fee arrangement. Sales on time-and-material type contracts are recognized at an amount equal to the direct labor hours expended multiplied by the contractual fixed rate per hour, plus the actual costs of material and other direct non-labor costs. On a time-and-material contract the fixed hourly rates include amounts for the cost of direct labor, indirect contract costs and profit. Cost-reimbursable or time-and-material contracts generally contain less estimation risks than fixed-price contracts.

25

The impact of revisions in profit estimates for all types of contracts are recognized on a cumulative catch-up basis in the period in which the revisions are made. Provisions for anticipated losses on contracts are recorded in the period in which they become evident. Amounts representing contract change orders or claims are included in sales only when they can be reliably estimated and their realization is reasonably assured. The revisions in contract estimates, if significant, can materially affect our results of operations and cash flows, as well as our valuations of contracts in process.

Goodwill and Identifiable Intangible Assets.    In accordance with Statement of Financial Accounting Standards (SFAS) No. 141, Business Combinations, we allocate the cost of acquired businesses (commonly referred to as the purchase price allocation) to the assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition. As part of the purchase price allocations for our acquired businesses, identifiable intangible assets are recognized as assets apart from goodwill if they arise from contractual or other legal rights, or if they are capable of being separated or divided from the acquired business and sold, transferred, licensed, rented or exchanged, unless the intangible asset is comprised of the assembled workforce of the acquired business.

Generally, the substantial majority of the intangible assets from the businesses that we acquire are derived from the intellectual capital of the management, administrative, scientific, engineering and technical employees of the acquired businesses. The success of our businesses is primarily dependent on the management, contracting, engineering and technical skills and knowledge of our employees, rather than productive capital (machinery and equipment). Generally, patents, trademarks and licenses are not material to our acquired businesses. Furthermore, our U.S. Government contracts (revenue arrangements) generally permit other companies to use our patents in most domestic work performed by such other companies for the U.S. Government. Therefore, the substantial majority of the intangible assets for our acquired businesses are recognized as goodwill.

The values assigned to acquired identifiable intangible assets for customer relationships and technology are determined, as of the date of acquisition, based on estimates and judgments regarding expectations for the estimated future after-tax cash flows from those assets over their lives, including the probability of expected future contract renewals and sales, less a cost-of-capital charge, all of which is discounted to present value. If actual future after-tax cash flows differ significantly from their estimates, we may be required to record an impairment charge to write down the identifiable intangible assets to their realizable values. The value assigned to goodwill equals the amount of the purchase price of the business acquired in excess of the sum of the amounts assigned to identifiable acquired assets, both tangible and intangible, less liabilities assumed. At December 31, 2004, we had goodwill of $4,054.8 million and identifiable intangible assets of $185.8 million.

We review goodwill and intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of these assets may not be recoverable, and also review goodwill annually in accordance with SFAS No. 142, Goodwill and Other Intangible Assets (SFAS 142). SFAS No. 142 requires that goodwill be tested, at a minimum, annually for each reporting unit using a two-step process. A reporting unit is an operating segment, as defined in paragraph 10 of SFAS No. 131, Disclosures About Segments of an Enterprise and Related Information, or a component of an operating segment. A component of an operating segment is a reporting unit if the component constitutes a business for which discrete financial information is available and is reviewed. Two or more components of an operating segment may be aggregated and deemed a single reporting unit if the components have similar economic characteristics. The first step is to identify any potential impairment by comparing the carrying value of the reporting unit to its fair value. If a potential impairment is identified, the second step is to compare the implied fair value of goodwill with the carrying value of the goodwill to measure the impairment loss. The fair value of a reporting unit is estimated using a discounted cash flow valuation approach, and is dependent on estimates for future sales, operating income, depreciation and amortization, income tax payments, working capital changes, and capital expenditures, as well as, expected growth rates for cash flows and long-term interest rates, all of which are impacted by economic conditions related to the industries in which we operate as well as conditions in the U.S. capital markets. A decline in estimated fair value of a reporting unit could result in an impairment charge to goodwill, which could have a material adverse effect on our business, financial condition and results of operations.

Pension Plan and Postretirement Benefit Plan Obligations.    The obligations for our pension plans and postretirement benefit plans and the related annual costs of employee benefits are calculated based on several long-term assumptions, including discount rates for employee benefit liabilities, rates of return on plan assets, expected annual rates for salary increases for employee participants in the case of pension plans, and expected annual increases in the costs of medical and other health care benefits in the case of postretirement benefit obligations. These long-term assumptions are subject to revision based on changes in interest rates, financial market conditions, expected versus actual returns on plan assets, participant mortality rates and other actuarial assumptions, including future rates of salary increases, benefit formulas and levels, and rates of increase in the costs of benefits. Changes in the assumptions, if significant, can materially affect the amount of annual net periodic benefit costs recognized in our results of operations from one year to the next, the liabilities for the pension plans and postretirement benefit plans, and our annual cash requirements to fund these plans.

Valuation of Deferred Income Tax Assets and Liabilities.    At December 31, 2004, we had net deferred tax assets of $119.1 million, including $3.8 million for loss carryforwards and $18.5 million for tax credit carryforwards which are subject to various limitations and will expire if unused within their respective carryforward periods. Deferred income taxes are determined separately for each of our tax-paying entities in each tax jurisdiction. The future realization of our deferred income tax assets ultimately depends on our ability to generate sufficient taxable income of the appropriate character (for example, ordinary income or capital gains) within the carryback and carryforward periods available under the tax law, and to a lesser extent, our ability to execute successful tax planning strategies. Based on our estimates of the amounts and timing of future taxable income and tax planning strategies, we believe that L-3 will be able to realize its deferred tax assets. A change in the ability of our operations to continue to generate future taxable income, or our ability to implement desired tax planning strategies, could affect our ability to realize the future tax deductions underlying our net deferred tax assets, and require us to provide a valuation allowance against our net deferred tax assets. The recognition of a valuation allowance would result in a reduction to net income and if significant, could have a material impact on our effective tax rate, results of operations and financial position in any given period.

Effective January 1, 2004, we combined our explosives detection systems (EDS) business into L-3 Communications Security and Detection Systems, our IMC business into L-3 Communications Government Services, Inc. (GSI), the EMP business into our ESSCO business and the Apcom business into our Communications Systems-East business (2004 Business Realignments). As a result of the 2004 Business Realignments, reclassifications between "Contracts, primarily U.S. Government" and "Commercial, primarily products" have been made to the prior period sales and operating income amounts, however, since EDS was primarily a U.S. Government contracting business prior to 2003, the sales and operating income for EDS were not reclassified from 2002. Specifically, $96.5 million of 2003 sales, $9.1 million of 2002 sales, $26.3 million of 2003 operating income and $6.1 million of 2002 operating loss was reclassified from "Contracts, primarily U.S. Government" to "Commercial, primarily products". Additionally, $30.6 million of 2003 sales, $9.2 million of 2002 sales, $2.1 million of 2003 operating income and $7.4 million of 2002 operating loss was reclassified from "Commercial, primarily products," to "Contracts, primarily U.S. Government". The 2004 Business Realignments and related reclassifications did not result in any changes to our consolidated results of operations, financial position or cash flow.

(2)	Operating margin is equal to operating income as a percentage of sales.

(3)	Sales are after intersegment eliminations. See Note 18 to the consolidated financial statements.

Effective January 1, 2004, we combined our IMC business into GSI. As a result of this realignment of management responsibilities, $29.1 million of 2003 sales, $2.3 million of 2002 sales, $3.9 million of 2003 operating income and $0.3 million of 2002 operating income was reclassified from the Specialized Products segment to the Training, Simulation & Government Services segment. This reclassification to our reportable segments did not result in any changes to our consolidated results of operations, financial position or cash flows.

(5)	During the 2004 Third Quarter, we changed the name of the reportable segment from Aviation Products & Aircraft Modernization to Aircraft Modernization, O&M and Products. The business and reporting units included in this reportable segment were not changed.

Year Ended December 31, 2004 Compared with Year Ended December 31, 2003

Consolidated sales increased by $1,835.4 million, or 36.3%, to $6,897.0 million for 2004 from $5,061.6 million for 2003. Organic sales growth for our defense businesses was 16.3%, or $721.6 million, driven by continued strong demand for our secure communications and ISR systems, aircraft modernization, aviation products, training and government services, training devices, sensors and imaging products and naval power equipment and services. Organic sales growth for our commercial and other non-military businesses was 6.6%, or $41.9 million, primarily due to increased volume for commercial aviation products and security products, partially offset by lower sales volume for explosives detection systems (EDS). The decrease in EDS sales was caused primarily by a later-than-expected receipt of an order from the U.S. Transportation and Security Administration. The increase in consolidated sales from acquired businesses was $1,071.9 million, or 21.2%. We define "organic sales growth," as the increase or decrease in sales for the current period compared to the prior period, excluding the increase in sales attributable to acquired businesses to the extent the acquired businesses were not included in our results of operations for the prior period, determined on a monthly basis. Our sales for "defense businesses" include our U.S. Government contractor businesses, all of which are presented under "Contracts, primarily U.S. Government" (Government Businesses) and commercial aviation products sold to military customers, which is presented under "Commercial, primarily products" (Commercial Businesses).

Sales from our Government Businesses increased by $1,753.9 million, or 39.8%, to $6,155.6 million for 2004 from $4,401.7 million for 2003. The increase in sales from acquired businesses was $1,037.1 million, or 23.6%. The acquired businesses include Aeromet, Klein, MAS, Vertex, and certain defense and aerospace assets of IPICOM, Inc., all of which were acquired in 2003, and AVISYS, Bay Metals, Beamhit, Brashear, Cincinnati Electronics, D.P. Associates, Inc. and the GEDD business, all of which were acquired in 2004. Sales from our Commercial Businesses increased by $81.5 million, or 12.4%, to $741.4 million for 2004 from $659.9 million for 2003. The increase in sales from the Avionics Systems and Flight Systems Engineering acquired businesses, which were acquired in 2003, and Infrared Products, which was acquired in 2004, was $34.8 million.

Consolidated costs and expenses increased by $1,667.8 million, or 37.2%, to $6,148.4 million for 2004 from $4,480.6 million for 2003. Costs and expenses for our Government Businesses increased by $1,613.0 million, or 41.7%, to $5,476.8 million for 2004 from $3,863.8 million for 2003. The costs and expenses related to the increase in sales from acquired businesses was $973.1 million. The remaining increase is primarily attributed to costs and expenses associated with the organic sales growth of our defense businesses. Cost of sales for L-3's U.S. Government contractor businesses include selling, general and

administrative (SG&A), independent research and development (IRAD) and bid and proposal (B&P) costs. These SG&A, IRAD and B&P costs are allowable indirect contract costs that are allocated to our U.S. Government contracts in accordance with U.S. Government regulations. We report SG&A, IRAD and B&P costs allocated to U.S. Government contracts as costs of sales when the related contract sales are recognized, rather than account for them as period expenses. SG&A, IRAD and B&P costs included in costs and expenses for L-3's Government Businesses were $582.8 million for 2004 and $499.9 million for 2003. The increase of $82.9 million was primarily attributable to the MAS, Vertex and Brashear acquired businesses and organic sales growth from our defense businesses. See Note 4 to our audited consolidated financial statements. Costs and expenses for our Commercial Businesses increased by $54.8 million, or 8.9%, to $671.6 million for 2004 from $616.8 million for 2003. Cost of sales increased by $41.9 million to $458.9 million for 2004 from $417.0 million for 2003. The increase in cost of sales was primarily due to increased costs attributable to the Avionics Systems acquired business and higher sales volume for our commercial aviation products. SG&A expenses increased by $0.9 million to $141.5 million for 2004 from $140.6 million for 2003, and declined as a percentage of sales to 19.1% from 21.3% due to cost and expense reductions and sales volume increases. R&D expenses increased by $12.0 million to $71.2 million for 2004 from $59.2 million for 2003, primarily due to development expenditures for Smartdeck™.

Consolidated operating income increased by $167.6 million, or 28.8%, to $748.6 million for 2004 from $581.0 million for 2003. Consolidated operating margin decreased to 10.9% from 11.5% for the 2004 compared to 2003. The changes in the operating margins for our segments are discussed below. Operating income for our Government Businesses increased by $140.9 million, or 26.2%, to $678.8 million for 2004 from $537.9 million for 2003. Operating margin declined by 1.2 percentage points to 11.0% for 2004 from 12.2% for 2003. Operating margin decreased primarily due to expected lower operating margins from the Vertex Aerospace acquired business. The 2003 operating income also included a $4.5 million gain related to the settlement of a claim. Operating income for our Commercial Businesses increased by $26.7 million, or 61.9%, to $69.8 million for 2004 from $43.1 million for 2003. Operating margin increased by 2.9 percentage points to 9.4% for 2004 from 6.5% for 2003, primarily because of cost reductions for microwave components, higher sales volume for commercial aviation products and cost and expense reductions at our PrimeWave Communications business. These increases were partially offset by development expenditures for Smartdeck™, certification costs for new commercial aviation products and fewer than expected sales of higher margin EDS systems.

Interest expense increased by $12.6 million to $145.3 million for 2004 from $132.7 million for 2003 because of higher levels of outstanding debt during 2004 compared to the levels of outstanding debt during 2003. Average outstanding debt during 2004 was $2,233.5 million compared to $2,059.5 million during 2003. Our outstanding debt increased as a result of the issuance of $650.0 million of 5 7/8% senior subordinated notes in November 2004, $400.0 million of 6 1/8% senior subordinated notes in December of 2003 and $400.0 million of 6 1/8% senior subordinated notes in May of 2003. The increase in our outstanding debt was partially offset by the early retirement of our $200.0 million of 8% senior subordinated notes in December 2004 and $180.0 million of 8½% senior subordinated notes in June of 2003 and the conversion into L-3 Holdings Common Stock of our $420.0 million of 4% senior subordinated convertible contingent debt securities (CODES) in October 2004 and $300.0 million of 5¼% convertible senior subordinated notes in January of 2004.

Other expense (income), net, for 2004 was $7.3 million of income and includes $6.8 million of interest and investment income. Other expense (income), net for 2003 was $0.2 million of income. The increase from 2003 to 2004 was primarily due to higher interest and investment income.

Minority interest in net income of consolidated subsidiaries increased by $5.4 million to $8.9 million for 2004 from 3.5 million for 2003, primarily due to net income for the Army Fleet Support LLC, which is 80% owned by L-3.

The income tax provision for 2004 and 2003 is based on an effective income tax rate of 36.0%.

Basic EPS increased by $0.65 to $3.54 for 2004 from $2.89 for 2003. Diluted EPS increased by $0.71 to $3.33 for 2004 from $2.62 for 2003. Net income for 2004 includes an after-tax debt retirement charge of $3.2 million, or $0.03 per diluted share, relating to the retirement of $200.0 million of 8% senior subordinated notes. Net income for 2003 includes an after-tax debt retirement charge of $7.2 million, or

30

---

$.06 per diluted share related to the retirement of $180.0 million of 8½% senior subordinated notes. Excluding these debt retirement charges from both periods, diluted EPS would have increased by $0.68 for 2004 compared to 2003.

Secure Communications & ISR

Sales within our Secure Communications & ISR segment increased by $224.2 million, or 15.6%, to $1,663.6 million for 2004 from $1,439.4 million for 2003. Organic sales growth was $190.3 million, or 13.2%, reflecting continued strong demand from the DoD and other U.S. Government agencies for our secure network communications, ISR systems and communications products. The increase in sales from acquired businesses was $33.9 million, or 2.4%, and was primarily attributable to Aeromet and certain defense and aerospace assets of IPICOM, Inc., which were acquired in 2003.

Operating income increased by $45.1 million to $218.0 million for 2004 from $172.9 million for 2003 because of higher sales volume for communications products and ISR systems and lower operating losses for the PrimeWave Communications business due to cost and expense reductions. Operating margin increased by 1.1 percentage points to 13.1% for 2004 from 12.0% for 2003, primarily because of organic sales growth for ISR systems and communications products and cost reductions and lower operating losses in 2004 as compared to 2003 for the PrimeWave Communications business. These improvements to operating margin were partially offset by a loss related to the design, development and testing activities on a production contract for transportable tactical satellite communications terminals, which reduced operating margin by 0.2 percentage points.

Training, Simulation & Government Services

Sales within our Training, Simulation & Government Services segment increased by $250.3 million, or 24.8%, to $1,259.6 million for 2004 from $1,009.3 million for 2003. Organic sales growth was $227.3 million, or 22.5%, driven by increased volume for both training and government services. The increase in sales from acquired businesses was $23.0 million. The acquired businesses include Beamhit and the GEDD business, both of which were acquired during the second quarter of 2004 and D.P. Associates, Inc., which was acquired on October 8, 2004.

Operating income increased by $33.7 million to $149.2 million for 2004 from $115.5 million for 2003 because of higher sales volume for training and operations services. Operating margin increased by 0.4 percentage points to 11.8% for 2004 from 11.4% for 2003 due to cost efficiencies from the growth in sales.

Aircraft Modernization, O&M and Products

Sales within our Aircraft Modernization, O&M and Products segment increased by $1,270.2 million, or 124.6%, to $2,289.8 million for 2004 from $1,019.6 million for 2003. The increase in sales from acquired businesses was $967.6 million. The acquired businesses include Vertex, MAS, Avionics Systems and Flight Systems Engineering, which were acquired during 2003, and AVISYS, which was acquired in June 2004. Organic sales growth was $302.6 million, or 29.7%, driven by higher sales for aircraft modernization, operations and maintenance, which includes the U.S. Army Aviation and Missile Command (AMCOM) contract, and commercial and military aviation products.

Operating income increased by $101.8 million to $249.6 million for 2004 from $147.8 million for 2003 because of higher sales volume, which was partially offset by lower operating margin. Operating margin declined by 3.6 percentage points to 10.9% for 2004 from 14.5% for 2003. Margins from acquired businesses, primarily Vertex, decreased operating margin by 3.2 percentage points. The remaining decrease was primarily due to higher sales volume of lower margin aircraft modification and logistics support under cost-reimbursable-type contracts, partially offset by higher margins for commercial aviation products.

Specialized Products

Sales within our Specialized Products segment increased by $90.7 million, or 5.7%, to $1,684.0 million for 2004 from $1,593.3 million for 2003. The increase in sales from acquired businesses was $47.4 million.

31

---

The acquired businesses include Klein, which was acquired in September 2003, and Bay Metals, Brashear and Infrared Products, which were acquired during 2004. Organic sales growth was $43.3 million, or 2.7%. The increase was driven by increased sales of $92.8 million primarily for training devices, imaging products, naval power equipment and services, maintenance of security systems and fuzing products. These increases were partially offset by volume declines of $49.5 million for EDS, ruggedized computers and displays and undersea warfare products.

Operating income decreased by $13.0 million to $131.8 million for 2004 from $144.8 million for 2003 primarily because of changes in product sales mix for security products and telemetry products, and a $4.5 million gain in 2003 related to a settlement of a claim recorded in 2003. These decreases were partially offset by operating income for naval power equipment businesses in 2004, as compared to operating losses in 2003, cost reductions for microwave components and higher volume for imaging products and naval power equipment and services. Operating margin decreased by 1.3 percentage points to 7.8% for 2004 from 9.1% for 2003. Operating margin decreased by 1.7 percentage points primarily due to lower margins for security products, including fewer than expected sales of higher margin EDS and 0.3 percentage points due to the settlement of a claim recorded in 2003. These decreases were partially offset by an increase of 0.7 percentage points for naval power equipment businesses.

Year Ended December 31, 2003 Compared with Year Ended December 31, 2002

Consolidated sales increased by $1,050.4 million, or 26.2%, to $5,061.6 million for 2003 from sales of $4,011.2 million for 2002. The increase in consolidated sales from acquisitions was $833.6 million, or 20.8%. Organic sales growth for our defense businesses was 15.4%, or $499.8 million, and was driven by continued strong demand for secure communications and intelligence, surveillance and reconnaissance (ISR) systems and products, aircraft modernization, simulation and training services, government services, and an increase in shipments of naval power equipment. Organic sales for our commercial businesses declined by 10.6%, or $45.4 million, due to the continued weakness in the aviation and communications markets. Sales for explosives detection systems (EDS) decreased $237.6 million primarily because the initial installation of EDS at major U.S. airports by the U.S. Transportation Security Administration (TSA) was completed by the end of 2002. Consolidated organic sales growth, excluding the EDS business, from both periods was 12.4%. Consolidated organic sales growth for all of our businesses, including the decline for the EDS business, was $216.8 million, or 5.4%.

Sales from our Government Businesses, which comprises our defense businesses, excluding commercial aviation products sold to military customers, and in 2002, our EDS business, increased by $820.4 million, or 22.9%, to $4,401.7 million for 2003 from $3,581.3 million for 2002. The increase in sales from acquired businesses was $659.7 million, or 18.4%. The acquired businesses include IS, Telos, ComCept, TMA, Electron Devices, Ruggedized Command & Control, IMC, Westwood, Wescam and Ship Analytics, which were acquired in 2002 and Aeromet, Klein, MAS, Vertex and certain defense and aerospace assets of IPICOM, Inc., which were acquired during 2003. Excluding sales from acquired businesses, sales increased by $253.5 million primarily because of organic sales growth from our defense businesses for ISR and secure communications systems and products, aircraft modernization, communications software and engineering support services, training services, navigation products and naval power equipment. These increases were partially offset by a decline in sales volume primarily from our EDS business, and to a lesser extent, from our fuzing products, training devices, undersea warfare products and display systems. Additionally, sales were reduced by $92.8 million because of a reclassification, primarily related to the EDS business, between our Government Businesses and our Commercial Businesses due to the 2004 Business Realignments discussed in the table above.

Sales from our Commercial Businesses increased by $230.0 million, or 53.5%, to $659.9 million for 2003 from $429.9 million for 2002. The increase in sales from acquired businesses was $173.9 million, or 40.5%. The acquired businesses include Detection Systems and Wolf Coach, which were acquired in 2002 and Avionics Systems, which was acquired during 2003. Excluding sales from acquired businesses, organic sales declined for our commercial businesses by $36.7 million, due primarily to lower revenues for aviation and communications products caused by weak demand in those commercial markets. Additionally, sales increased by $92.8 million as a result of the reclassification due to the 2004 Business Realignments.

Consolidated costs and expenses increased by $923.4 million to $4,480.6 million for 2003 from $3,557.2 million for 2002, consistent with the increase in sales.

Costs and expenses for our Government Businesses increased by $724.8 million to $3,863.8 million for 2003 from $3,139.0 million for 2002. Approximately 81% of the increase is attributable to our acquired businesses. The remaining increase is primarily attributed to organic sales growth from our defense businesses for ISR and secure communications systems and products, aircraft modernization, communications software and engineering support services, training services, navigation products and naval power equipment. These increases were partially offset by declines from our EDS business, fuzing products, training devices and display systems due to lower volume. SG&A, IRAD and B&P costs included in cost of sales for our Government Businesses were $499.9 million, or 11.4% of sales for 2003, compared to $432.8 million, or 12.1% of sales for 2002 (See Notes 2 and 4 to our consolidated financial statements).

Costs and expenses for our Commercial Businesses increased by $198.6 million to $616.8 million for 2003 from $418.2 million for 2002. The increase was primarily due to increased sales attributable to our acquired businesses, as well as a $3.9 million provision for bad debt and inventory for the PrimeWave Communications business. SG&A expenses increased by $28.6 million to $140.6 million or 21.3% of sales for 2003 from $112.0 million or 26.1% of sales for 2002. The increase was primarily attributable to acquired businesses and increased costs for security products due to maintenance costs associated with detection systems placed in service. This increase was partially offset by lower SG&A expenses at the PrimeWave Communications business and our commercial communications products businesses due to cost and expense reductions. Research and development (R&D) expenses increased by $23.5 million to $59.2 million for 2003 from $35.7 million for 2002. The increase was primarily due to the Avionics Systems acquired business and development expenses for cargo security products, partially offset by lower R&D expenses incurred at the PrimeWave Communications business because of cost and expense reductions.

Consolidated operating income increased by $127.0 million to $581.0 million for 2003 from $454.0 million for 2002. The increase was primarily due to higher sales from all of our segments. Consolidated operating margin increased slightly by 0.2 percentage points to 11.5% for 2003 from 11.3% for 2002. The changes in the operating margins for our segments are discussed below.

Operating income for our Government Businesses increased by $95.6 million to $537.9 million for 2003 from $442.3 million for 2002. Operating income was reduced by $22.9 million because of the reclassification due to the 2004 Business Realignments. Operating margin declined slightly by 0.1 percentage points to 12.2% for 2003 from 12.3% for 2002. The reclassification due to the 2004 Business Realignments reduced operating margin by 0.3 percentage points. Operating margin increased by 0.2 percentage points primarily due to sales growth and cost improvements for ISR and secure communications systems and products and naval power equipment.

Operating income for our Commercial Businesses increased by $31.4 million to $43.1 million for 2003 from $11.7 million for 2002. Operating income increased by $22.9 million because of the reclassification due to the 2004 Business Realignments. Operating margin improved by 3.8 percentage points to 6.5% for 2003 from 2.7% for 2002. The reclassification due to the 2004 Business Realignments increased operating margin by 3.0 percentage points. The remaining increase was due to lower losses from certain commercial businesses due to cost and expense reductions and higher margins from the Avionics Systems acquired business, partially offset by lower margins on commercial aviation products and microwave components due to lower sales volume and higher development expenses for cargo security products.

Interest expense increased by $10.2 million to $132.7 million for 2003 from $122.5 million for 2002. The increase is attributable to the higher average outstanding debt during 2003 and lower savings from fixed-to-variable interest rate swap agreements of $1.0 million.

Other income decreased by $4.7 million to $0.2 million in 2003 from $4.9 million in 2002. The decrease was due to lower interest income earned because of lower average cash and cash equivalents balances, a loss of $2.2 million recorded related to the sale of the commercial broadband test equipment assets of our Celerity business and an increase in losses on our investments accounted for using the equity method during 2003 compared to 2002.

The 2003 period includes a charge of $11.2 million ($7.2 million after-tax, or $0.06 per diluted share) for the early retirement of $180 million of our 8½% Senior Subordinated Notes due 2008. See "Liquidity

and Capital Resources." The 2002 period includes a charge of $16.2 million ($9.9 million after-tax, or $0.09 per diluted share) for the early retirement of $225 million of our 10 3/8% Senior Subordinated Notes due 2007.

Minority interest decreased by $2.7 million to $3.5 million for 2003 from $6.2 million for 2002 because of lower net income for Aviation Communications and Surveillance Systems (ACSS) due to lower sales caused by weakness in the commercial aviation market during 2003 and higher product development expenses.

The income tax provision for 2003 is based on an effective income tax rate of 36.0%, compared with an effective income tax rate of 35.5% for 2002.

Basic earnings per share (EPS) before cumulative effect of a change in accounting principle increased by $0.56 to $2.89 for 2003 from $2.33 for 2002. Diluted EPS before cumulative effect of a change in accounting principle increased by $0.49 to $2.62 for 2003 from $2.13 for 2002. Net income for 2002 includes a charge, net of income taxes, of $24.4 million ($0.28 per basic share and $0.23 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 EPS for 2002 was $2.05 and diluted EPS for 2002 was $1.90.

Diluted weighted-average common shares outstanding increased by 8.3% to 113.9 million for 2003 from 105.2 million for 2002. The increase principally reflects the additional shares outstanding from the sale of 14.0 million shares of L-3 Holdings common stock on June 28, 2002.

Secure Communications & ISR

Sales within our Secure Communications & ISR segment increased by $386.1 million, or 36.7%, to $1,439.4 million for 2003 from $1,053.3 million for 2002. Organic sales growth was $250.4 million, or 23.8%, due to continued strong demand and increased spending by the DoD and other U.S. Government agencies for our secure communications and ISR systems and products, which were partially offset by a decline in sales of $5.5 million for the PrimeWave Communications business. The increase in sales from acquired businesses was $135.7 million. The acquired businesses include IS and ComCept, which were acquired during 2002, and Aeromet and certain defense and aerospace assets of IPICOM, Inc., which were acquired during 2003.

Operating income increased by $69.4 million to $172.9 million for 2003 from $103.5 million for 2002 because of higher sales and operating margin. Operating margin increased to 12.0% for 2003 from 9.8% for 2002 because of higher organic sale growth for defense systems and products, cost improvements and lower losses at our PrimeWave Communications business.

Training, Simulation & Government Services

Sales within our Training, Simulation & Government Services segment increased by $200.7 million, or 24.8%, to $1,009.3 million for 2003 from $808.6 million for 2002. Organic sales growth was $81.7 million, or 10.1%, driven by training and government services, including communications software support and engineering support. The increase in sales from the Telos, TMA, IMC and Ship Analytics acquired businesses, which were all acquired in 2002, was $119.0 million.

Operating income increased by $18.7 million to $115.5 million for 2003 from $96.8 million for 2002 because of higher sales, which were partially offset by lower operating margin. Operating margin declined by 0.6 percentage points to 11.4% for 2003 from 12.0% for 2002. The decrease was primarily due to higher sales from cost-reimbursable type and time and material type contracts, which generally are less profitable than fixed-priced type contracts. Margins increased by 0.3 percentage points from acquired businesses.

Aircraft Modernization, O&M and Products

Sales within our Aircraft Modernization, O&M and Products segment increased by $342.1 million, or 50.5%, to $1,019.6 million for 2003 from $677.5 million for 2002. Organic sales growth was $129.9 million, or 19.2%, primarily due to $144.7 million for aircraft modernization and modification driven by DoD

demand. This increase was partially offset by volume declines of $10.8 million for commercial aviation products caused by the continued weakness in the commercial aviation markets and volume declines of $4.0 million primarily for display systems due to the timing of contractual shipments. The increase in sales from acquired businesses was $212.2 million. The acquired businesses include IS, which was acquired in 2002, and Avionics Systems, MAS and Vertex, which were acquired in 2003.

Operating income increased by $42.1 million to $147.8 million for 2003 from $105.7 million for 2002 because of higher aircraft modernization sales, which were partially offset by lower sales for commercial aviation products and lower operating margin. Operating margin declined by 1.1 percentage points to 14.5% for 2003 from 15.6% for 2002. Volume declines for commercial aviation products, which have higher margins than aircraft modification sales, decreased operating margin by 0.9 percentage points. Similarly, margins decreased by 0.4 percentage points primarily due to volume growth for aircraft modernization, which earns lower margins than commercial aviation products. These decreases were partially offset by the Avionics Systems and MAS acquired businesses, which increased margin by 0.2 percentage points.

Specialized Products

Sales within our Specialized Products segment increased by $121.5 million, or 8.3%, to $1,593.3 million for 2003 from $1,471.8 million for 2002. Organic sales declined 16.7%, or $245.2 million, or $7.6 million, or 0.5%, excluding the decline for EDS. EDS sales declined by $237.6 million (discussed below). Volume declined by $46.4 million for fuzing and acoustic undersea warfare products and training devices because of certain contracts approaching their scheduled completion and the timing of sales on 2003 orders. Volume declined by $22.3 million for telemetry products and microwave components due to the continued weakness in the commercial communications markets. These decreases were partially offset by an increase of $46.6 million for naval power equipment due to higher shipments arising from the resolution of the production and quality control issues at the SPD Electrical Systems business and $14.5 million primarily for FTSATs and guidance products due to strong demand from the DoD. The increase in sales from acquired businesses was $366.7 million. The acquired businesses include Detection Systems, Ruggedized Command & Control, Electron Devices, Wolf Coach, Westwood and Wescam, all of which were acquired in 2002, and Klein, which was acquired in 2003.

Sales of EDS declined by $237.6 million to $101.5 million for 2003 compared with $339.1 million for 2002, primarily because the initial installation of EDS at major U.S. airports by the TSA was completed by the end of 2002, which reduced the TSA's procurement requirements for new systems.

Operating income decreased by $3.2 million to $144.8 million for 2003 from $148.0 million for 2002. Operating margin decreased by 1.0 percentage points to 9.1% for 2003 from 10.1% for 2002. Lower sales for EDS reduced operating margin by 0.6 percentage points. Volume declines for telemetry, fuzing and undersea warfare products lowered operating margin by 0.5 percentage points. Lower margins from acquired businesses reduced operating margin by 0.6 percentage points. The resolution of production quality problems for naval power equipment caused increased shipments and reduced rework costs, which increased operating margin by 0.5 percentage points. The settlement of a claim increased operating margin by 0.2 percentage points.

Liquidity and Capital Resources

Balance Sheet

Contracts in process increased by $363.7 million to $1,979.0 million at December 31, 2004 from $1,615.3 million at December 31, 2003. The increase included (i) $77.1 million related to business acquisitions, (ii) $41.2 million of non-cash reclassifications to billed and unbilled receivables associated with certain billings in excess of costs and estimated profits and (iii) $245.4 million principally from:

•	increases of $121.3 million in unbilled contract receivables due to sales exceeding deliveries and billings for secure network communications, ISR systems, communications products, training and government services, aircraft modernization and maintenance and the AMCOM contract;

•	increases of $84.8 million in billed receivables because of higher sales volume of secure network communications systems, training devices and aircraft modernization;

35

---

•	increases of $24.3 million in inventoried contract costs primarily for aircraft modernization, secure network communications and ruggedized computers; and

•	increases of $15.0 million in inventories at lower of cost or market due to increases for security products.

L-3's days receivable outstanding (DRO) was 71.8 at December 31, 2004, compared with 70.3 at December 31, 2003. We calculate our DRO by dividing (i) our aggregate end of period billed receivables and net unbilled contract receivables, by (ii) our sales for the last twelve-month period adjusted, on a pro forma basis, to include sales from business acquisitions that we completed as of the end of the period (which amounted to $7,184.7 million), multiplied by 365.

L-3's billed receivables, net of uncollectible account allowances, increased by $144.6 million to $781.9 million at December 31, 2004, compared to $637.3 million at December 31, 2003. The increase in billed receivables was primarily from L-3's U.S. Government contractor businesses and related to organic sales growth, as well as the 2004 business acquisitions. The uncollectible accounts allowance decreased by $8.7 million to $16.5 million at December 31, 2004, compared to $25.2 million at December 31, 2003, because of write-offs of uncollectible accounts in 2004. The uncollectible accounts relate to L-3's commercial businesses. Our U.S. Government and allied foreign government customers, which generated 88.9% of L-3's sales for 2004, present very low uncollectible account risks due to their high credit quality and, therefore, generally require no uncollectible account allowances.

L-3's days inventory held (DIH) was 33.3 at December 31, 2004, compared with 36.3 at December 31, 2003. We calculate DIH by dividing (i) our aggregate end of period net inventoried contract costs and inventories at lower of cost or market, by (ii) our cost of sales for the last twelve-month period adjusted on a pro forma basis to include cost of sales from business acquisitions that we completed as of the end of the period (which amounted to $6,200.1 million), multiplied by 365.

The increase in property, plant and equipment (PP&E) during 2004 was principally related to the Infrared Products, Cincinnati Electronics and Electronics Systems acquired businesses. The percentage of depreciation expense to average gross PP&E increased to 12.4% for 2004 from 11.9% for 2003. The increase was attributable to the impact of business acquisitions completed during 2003. We did not change any of the depreciation methods or assets estimated useful lives that L-3 uses to calculate its depreciation expense.

Goodwill increased by $402.4 million to $4,054.8 million at December 31, 2004, from $3,652.4 million at December 31, 2003. The increase was comprised of (i) $366.5 million for business acquisitions completed during 2004, (ii) $36.0 million for increases to purchase price payments for certain acquisitions completed prior to January 1, 2004, related to final closing date net assets of the acquired businesses and contingent purchase price adjustments or earnouts, which were resolved during the period, and (iii) a decrease of $0.1 million primarily related to final estimates of fair value for acquired assets and liabilities assumed in connection with business acquisitions completed prior to January 1, 2004.

The increase in accounts payable was due to increased purchases from third-party vendors and subcontractors to support higher volumes for sales and related contracts-in-process, and the timing of payments for such purchases and to business acquisitions completed during 2004. The increase in accrued employment costs was due to the timing of payments of salaries and wages to employees and to business acquisitions completed during 2004. The increase in billings in excess of costs and estimated profits was primarily due to an increase in collections for milestone billings on contracts for training devices and services related to the completion of certain performance milestones and an increase for contracts in process with credit balances. The decrease in other current liabilities was primarily due to the payment of the remaining purchase price for the acquisition of certain aerospace and defense assets of IPICOM, Inc., and to cash payments for costs incurred in excess of contract values for certain contracts in a loss position. The increase in pension and postretirement benefit liabilities was primarily due to the increase in the minimum liability of $23.1 million, discussed below. The increase in other liabilities was due to amounts from our acquired businesses.

Customer advances increased by $49.3 million because collections exceeded liquidations, primarily related to cash payments received on contracts with foreign customers for ISR systems, acoustic undersea

36

---

warfare products and aircraft modernization and to the business acquisitions we completed during 2004. 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. 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 timing of revenue recognition for a contract because customer advances are a contract financing method.

Pension Plans

L-3 maintains defined benefit pension plans covering employees at certain of its businesses. At December 31, 2004, our balance sheet included a pension benefits liability of $273.8 million, an increase of $40.4 million from $233.4 million at December 31, 2003. The increase is due to pension expense recognized exceeding our pension funding and an increase in the minimum liability of $23.1 million. At the end of 2004, L-3's projected benefit obligation, which includes accumulated benefits plus the incremental benefits attributable to projected future salary increases for covered employees, was $1,131.6 million and exceeded the fair value of L-3's pension plan assets of $734.6 million by $397.0 million. At the end of 2003, L-3's projected benefit obligation was $902.1 million and exceeded the fair value of L-3's pension plan assets of $561.7 million by $340.4 million. The increase in the unfunded status of our pension plans of $56.6 million from $340.4 million at the end of 2003 to $397.0 million at the end of 2004 was principally due to the $62.2 million actuarial loss that we experienced in 2004. Our 2004 actuarial loss was primarily due to the reduction in the discount rate by 25 basis points to 6.00% at the end of 2004 from 6.25% at the end of 2003, which increased the present value of L-3's projected benefit obligations at the end of 2004 by $44.0 million. The difference between the unfunded status amount of $397.0 million at the end of 2004 and the pension liability recorded on our balance sheet of $273.8 million is attributable to the cumulative net unrecognized actuarial losses. In accordance with SFAS No. 87, Employer's Accounting for Pensions, the actuarial gains and losses that our pension plans experience are not recognized in pension expense in the year incurred, but rather deferred and amortized to pension expense in future periods over the estimated average remaining service periods of the covered employees. (See Note 16 to our consolidated financial statements.)

L-3 uses a November 30 measurement date to determine its end of year (December 31) pension benefit obligations and fair value of pension plan assets, and a fiscal year ending November 30 to determine its annual pension expense, including actual returns on plan assets. L-3's actual return on plan assets for 2004, based on the fiscal year ended November 30, 2004, was $56.8 million, or 10.1%, on the fair value of plan assets at the beginning of the fiscal year.

Our pension expense for 2004 was $74.8 million. We expect pension expense for 2005 to be between $90 million and $100 million. As discussed above, at the end of 2004 we reduced our discount rate from 6.25% to 6.00%, which will increase the interest cost component of pension expense for 2005. The higher interest cost in our estimated 2005 pension expense is expected to be substantially offset by the increase of $172.8 million in our pension plan assets during 2004, which will increase our expected return on plan assets by approximately $15.0 million, and decrease our estimated pension expense by the same amount. Our actual pension expense for 2005 will be based upon a number of factors, including the effect of any additional business acquisitions for which we assume liabilities for pension benefits, actual pension plan contributions and changes (if any) to our pension assumptions for 2005, including the discount rate, expected long-term return on plan assets and salary increases.

Our contributions for the full year 2004 were $60.9 million. For 2005, we expect to contribute approximately $70.0 million to our pension plans. A substantial portion of our pension plan contributions for L-3's businesses that are U.S. Government contractors are recoverable as allowable indirect contract costs at amounts generally equal to the annual pension contributions.

Our projected benefit obligation and annual pension expense are significantly affected by the discount rate assumption we use. For example, an additional reduction to the discount rate of 25 basis points would have increased our projected benefit obligation at December 31, 2004 by approximately $43 million, and our estimated pension expense for 2005 by approximately $7 million. Conversely, an increase

37

---

to the discount rate of 25 basis points would have decreased our projected benefit obligation at December 31, 2004 by approximately $44 million, and our estimated pension expense for 2005 by approximately $7 million.

Our shareholders' equity at December 31, 2004 reflects a non-cash charge of $5.3 million (net of tax) to record the increase in accumulated other comprehensive loss due to additional minimum pension liability recognized for the year ended December 31, 2004 in accordance with SFAS No. 87. This non-cash charge had no effect on our compliance with the financial covenants of our debt agreements and did not impact our results of operations for 2004.

Statement of Cash Flows

Our cash position was $653.4 million at December 31, 2004 and $134.9 million at December 31, 2003 and 2002. The table below provides a summary of our cash flows for the periods indicated.

				Year Ended December 31,
				2004				2003				2002
				(in millions)
Net cash from operating activities				$	620.7			$	456.1			$	318.5
Net cash used in investing activities					(555.5	)			(1,088.1	)			(1,810.5	)
Net cash from financing activities					453.3				632.0				1,265.9
Net increase (decrease) in cash				$	518.5			$	—			$	(226.1	)

Operating Activities

We generated $620.7 million of cash from operating activities during 2004, an increase of $164.6 million from the $456.1 million generated during 2003. Net income increased by $104.2 million. Non-cash expenses increased by $63.4 million to $316.1 million in 2004 from $252.7 million in 2003, primarily for depreciation and amortization, contributions to employee savings plans in L-3 Holdings common stock and deferred income taxes. Deferred income taxes increased by $28.7 million to $123.4 million for 2004 from $94.7 million for 2003, primarily because of larger estimated tax deductions arising from our recent business acquisitions. During 2004, we used cash for changes in operating assets and liabilities of $77.3 million, compared to $74.2 million for 2003. The use of cash for contracts in process was primarily driven by increases in unbilled contract receivables and billed receivables arising from the organic sales growth for our businesses, as discussed above under "Liquidity and Capital Resources — Balance Sheet" and "Results of Operations". The use of cash for other current assets was primarily due to deposits paid to vendors during 2004. The use of cash for other assets was primarily due to investments in equipment for training devices and airport security systems leased to customers and capitalized software development costs for new products. The source of cash for accounts payable was due to increased purchases of materials, components and services required for the increase in sales during the year and the timing of payments for such purchases. The increase in the number of employees and the timing of payments for salaries and wages was a source of cash because costs and expenses for salaries and wages exceeded the cash payments. The source of cash for billings in excess of costs and estimated profits was due to cash collections for milestone billings on certain contracts primarily for training devices. The source of cash related to customer advances was due to receipt on certain foreign contracts awarded during the 2004 fourth quarter. The use of cash for other current liabilities was due to the payment upon settlement of a foreign currency hedging forward contract and cash payments for costs incurred in excess of estimated contract values for certain contracts in a loss position. The source of cash from the change in pension and postretirement benefit liabilities was due to expenses exceeding related cash contributions. Pension plan contributions in 2004 amounted to $60.9 million, and exceeded our originally planned contributions for 2004 by more than $5 million. We expect to contribute approximately $70.0 million to our pension plans in 2005.

During 2003, we generated $456.1 million of cash from operating activities, an increase of $137.6 million from $318.5 million generated during 2002. Net income increased by $99.5 million. Non-cash expenses increased by $14.9 million to $252.7 million in 2003 from $237.8 million in 2002, primarily for

depreciation and amortization, contributions to employee savings plans in L-3 Holdings common stock and deferred income taxes. During 2003, we used cash for changes in operating assets and liabilities of $74.2 million, compared to $97.4 million in 2002.

Our cash flows from operating activities during 2003 reflect increases in unbilled receivables and other assets. The use of cash for accounts payable was due to the timing of payments. The use of cash for other current liabilities was to fund contracts in a loss position for which estimated costs exceeded the estimated contract value, and was partially offset by cash collections for milestone billings in excess of costs incurred primarily for training devices. The timing of payments to employees for salaries and wages was a source of cash. Pension plan contributions in 2003 amounted to $60.8 million. The source of cash from other liabilities was generated primarily from terminating interest rate swap agreements. During 2003, we terminated interest rate swap agreements, which is discussed in "Derivative Financial Instruments", and generated cash proceeds related to deferred gains on them of $19.9 million, of which $2.1 million was recorded in other current liabilities and $17.8 million was recorded in other liabilities. For 2002, we also terminated interest rate swap agreements and generated cash proceeds related to net deferred gains on them of $16.8 million.

Our cash flows from operating activities during 2002 reflect increases in billed and unbilled receivables, other current assets and other assets. The use of cash related to customer advances was due to liquidations on certain foreign contracts. The use of cash for other current liabilities was to fund contracts in a loss position for which estimated costs exceed the estimated contract value, and was partially offset by an increase in accrued warranty costs primarily for explosive detection systems delivered in 2002. The timing of payments to employees for salaries and wages, as well as the timing of interest payments, was a source of cash. The source of cash in other liabilities was primarily due to deferred gains on the termination of our swap agreements. Pension plan contributions in 2002 amounted to $47.4 million.

Our cash from operating activities includes interest payments on debt of $138.2 million for 2004, $119.9 million for 2003 and $109.3 million for 2002. Our interest expense also includes amortization of deferred debt issue costs and deferred gains on terminated interest rate swap agreements, which are non-cash items.

Our cash from operating activities includes income tax payments, net of refunds, of $37.0 million for 2004, $17.3 million for 2003 and $2.1 million for 2002. Our income tax payments were substantially less than our provisions for income taxes reported on our statements of operations primarily because of income tax deductions from our acquired businesses structured as asset purchases and income tax deductions for compensation expense arising from the exercise of employee stock options. The income tax deductions from the exercise of employee stock options are accounted for as a reduction to current income taxes payable and an increase to shareholders' equity (see Note 13 to our consolidated financial statements). L-3 receives substantial income tax deductions from its business acquisitions that are structured as asset purchases for income tax purposes. The effect of these income tax deductions is that our cash payments for income taxes are less than our provision for income taxes reported on the statement of operations. This difference is presented in the deferred income tax provision on our statement of cash flows. The deferred income tax provision primarily results from deducting amortization of tax intangibles, including goodwill, from the business acquisitions structured as asset purchases on L-3's income tax returns over 15 years, in accordance with income tax rules and regulations, while no goodwill amortization is recorded for financial reporting purposes, in accordance with SFAS No. 142. We expect that the business acquisitions L-3 has completed through December 31, 2004 will continue to generate substantial annual deferred tax benefits through 2019. While these income tax deductions are reported as changes to deferred income tax liabilities and assets, they are not differences that are scheduled to reverse in future periods from normal operations. Rather, they will only reverse if L-3 sells its acquired businesses or incurs a goodwill impairment loss for them, because in either case, L-3's financial reporting amounts for goodwill would be greater than the income tax basis for goodwill. L-3 also receives significant income tax deductions and deferred tax benefits from its acquired businesses structured as asset purchases for income tax purposes from accelerated depreciation of plant and equipment.

Investing Activities

During 2004, we used $473.4 million of cash for business acquisitions. We paid $424.0 million in connection with our 2004 business acquisitions discussed above. We also paid $11.5 million for the final contractual purchase price adjustment for the Vertex acquired business. We also paid $37.9 million primarily for the remaining contractual purchase price for the IPICOM, Inc. assets, and for earnouts.

During 2003, we invested $1,014.4 million to acquire businesses, primarily for Vertex, Avionics Systems and MAS. During 2002, we invested $1,742.1 million to acquire businesses, primarily for Integrated Systems and Detection Systems. Cash used for business acquisitions included earnout payments on certain business acquisitions of $11.4 million for 2004, $8.5 million for 2003, and $1.8 million for 2002.

On February 3, 2005, we acquired substantially all of the Marine Controls division of CAE and we will acquire the remaining business operations following the receipt of required approvals. On February 25, 2005, we acquired the Propulsion Systems business unit of General Dynamics. On February 28, 2005, we acquired the Electron Dynamic Devices business of the Boeing Company. The aggregate purchase price paid in cash for these business acquisitions was $471.8 million. We financed these acquisitions using cash on hand.

Financing Activities

Debt

Senior Credit Facilities.    At December 31, 2004, the senior credit facilities were comprised of a $500.0 million five-year revolving credit facility maturing on May 15, 2006 and a $250.0 million 364-day revolving facility. The 364-day revolving credit facility expired on February 22, 2005.

At December 31, 2004, available borrowings under our senior credit facilities were $677.5 million, after reductions for outstanding letters of credit of $72.5 million. There were no outstanding borrowings under our senior credit facilities at December 31, 2004.

On March 9, 2005, we entered into a new five-year senior revolving credit facility maturing on March 9, 2010 and allowing for total aggregate borrowings of up to $1.0 billion. At March 9, 2005, available borrowings under our new senior credit facility were approximately $906 million, after reductions for outstanding letters of credit of approximately $94 million. At the time we entered into this facility, our existing senior credit facility was terminated.

Certain lenders and the administrative agent under the existing senior credit facility and the new senior credit facility have provided us with various financial advisory, investment banking, commercial banking and other services from time to time, for which they have received customary fees.

Redemptions and Related Conversion of Convertible Debt into Common Stock.    On October 5, 2004, L-3 Holdings announced a full redemption of all the $420.0 million of its 4.00% Senior Subordinated Convertible Contingent Debt Securities (CODES) due 2011, which expired on Thursday, October 21, 2004. On October 21, 2004, holders of $419.8 million of the principal amount of CODES exercised their conversion rights and converted such CODES into 7,800,797 shares of L-3 Holdings common stock. The remaining $0.2 million of the CODES were redeemed for cash on October 25, 2004, at a redemption price of 102.0% of the principal amount, plus accrued and unpaid interest (including contingent interest) to October 25, 2004. On December 22, 2003, L-3 Holdings announced a full redemption of $300.0 million of its 5.25% Convertible Senior Subordinated Notes due 2009 (Convertible Notes), which expired on January 9, 2004. Holders of $299.8 million of the Convertible Notes exercised their conversion rights and converted such notes into 7,357,327 shares of L-3 Holdings' common stock. The remaining $0.2 million of Convertible Notes were redeemed for cash.

Redemptions of Senior Subordinated Notes.    On November 12, 2004, L-3 Communications initiated a full redemption of all of the outstanding $200.0 million aggregate principal amount of 8% Senior Subordinated Notes due 2008. Such notes were redeemed by us at a redemption price of 102.667% of the principal amount thereof, plus accrued and unpaid interest. We completed this redemption on December

40

---

13, 2004. In connection with the early redemption of the $200.0 million of 8% Senior Subordinated Notes, we recorded a pre-tax debt retirement charge of $5.0 million.

On May 21, 2003, L-3 Communications 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. During 2003, we recorded a pre-tax charge of $11.2 million.

On June 6, 2002, L-3 Communications commenced a tender offer to purchase any and all of its $225.0 million aggregate principal amount of 10 3/8% Senior Subordinated Notes due 2007. The tender offer expired on July 3, 2002. On June 25, 2002, L-3 Communications sent a notice of redemption for all of its 10 3/8% Senior Subordinated Notes due 2007 that remained outstanding after the expiration of the tender offer. Upon sending the notice, the remaining notes became due and payable at the redemption price as of July 25, 2002. During 2002, we recorded a pre-tax charge of $16.2 million.

Debt Issuances.    The table below presents a summary of our issuances of debt obligations for 2002, 2003 and 2004. Our outstanding debt obligations, all of which are senior subordinated debt, are rated as of January 2005 as BB+ by Standard & Poor's, BB by Fitch Ratings and Ba3 by Moody's. For additional details about the terms of our debt, see Note 8 to our consolidated financial statements.

Description of Debt Issuances				Issue Date				Principal Amount				Discount				Commissions and Other Offering Expenses				Net Proceeds				Semi-Annual Interest Payment Dates

(1)	The net proceeds from this offering were used to redeem the 8% Senior Subordinated Notes due 2008 and to increase cash and cash equivalents.

(2)	The net proceeds from this offering were used to repay $275.0 million of borrowings outstanding under our senior credit facilities and to increase cash and cash equivalents.

(3)	The net proceeds from this offering were used to redeem the 8½% Senior Subordinated Notes due 2008 and to increase cash and cash equivalents.

(4)

The net proceeds from this offering and the concurrent sale of 14.0 million shares of our common stock, discussed below under "Equity," were used to (a) repay $500.0 million borrowed on March 8, 2002, under our senior subordinated bridge loan facility, (b) repay the indebtedness outstanding under our senior credit facilities, (c) repurchase and redeem the 10 3/8% Senior Subordinated Notes due 2007 (discussed above) and (d) increase cash and cash equivalents.

Debt Covenants and Other Provisions.    The new senior credit facility, which was entered into on March 9, 2005, and senior subordinated notes agreements contain financial covenants and other restrictive covenants. See Note 8 to our consolidated financial statements for a description of our debt and related financial covenants under our new senior credit facility. We are in compliance with those covenants in all material respects. The new senior credit facility and the senior subordinated notes indentures limit the ability of L-3 Communications to pay dividends to and make investments in L-3 Holdings, subject to exceptions, as described in Note 8 to our consolidated financial statements.

The new senior credit facility contains cross default provisions that are triggered when a payment default occurs or certain other defaults occur that would allow the acceleration of indebtedness, guarantee obligations or certain other agreements of L-3 Communications or its subsidiaries in an aggregate amount of at least $40.0 million and those defaults (other than payment defaults and defaults that have resulted in acceleration) have not been cured after 10 days. The senior subordinated notes indentures contain cross acceleration provisions that are triggered when holders of the indebtedness of L-3 Holdings, L-3

41

---

Communications or their restricted subsidiaries (or the payment of which is guaranteed by such entities) accelerate at least $10.0 million in aggregate principal amount of those obligations. The new senior credit facility and the senior subordinated notes indentures also contain other customary events of default.

The borrowings under the new senior credit facility are guaranteed by L-3 Holdings and by substantially all of the material wholly-owned 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 substantially all of L-3 Communications' restricted subsidiaries other than its foreign subsidiaries. The guarantees of the senior subordinated notes rank pari passu with one another and are junior to the guarantees of the new senior credit facility.

In the event that the long-term debt rating of L-3 Communications is reduced below BBB−, or the equivalent. by two of the three rating agencies, Standard & Poor's Rating Services, Moody's Investors Service, Inc., or Fitch Ratings, L-3 Holdings will be required, within 45 business days, to pledge 100% of the capital stock of L-3 Communications, and L-3 Communications and each subsidiary guarantor will be required to pledge 100% of the capital stock of each of their material wholly-owned domestic subsidiaries and 65% of their material wholly-owned foreign subsidiaries, in favor of the lenders under the new senior credit facility.

Equity

In January of 2004, L-3 Holdings announced that its Board of Directors had declared L-3's first quarterly cash dividend of $0.10 per share, payable on March 15, 2004. L-3 Holdings' Board of Directors declared three additional quarterly dividends of $0.10 per share, all of which were paid in 2004. L-3 Holdings paid cash dividends of $43.4 million in aggregate to shareholders in 2004. The 2004 cash dividends were paid on March 15, June 15, September 15 and December 15.

On February 10, 2005, we announced that our Board of Directors had increased L-3's regular quarterly cash dividend by 25% to $0.125 per share, payable on March 15, 2005, to shareholders of record at the close of business on February 22, 2005. On February 22, 2005, L-3 Holdings had 116,333,428 shares of common stock outstanding.

On June 28, 2002, L-3 Holdings sold 14.0 million shares of its common stock in a public offering for $56.60 per share. Upon closing, we received net proceeds of $766.8 million after deducting underwriting discounts and commissions and other offering expenses. The net proceeds from this sale and the concurrent sale of senior subordinated notes by L-3 Communications were used to (i) repay $500.0 million borrowed on March 8, 2002, under our senior subordinated bridge loan facility, (ii) repay the indebtedness outstanding under our senior credit facilities, (iii) repurchase and redeem the 10 3/8% Senior Subordinated Notes due 2007 discussed above and (iv) increase cash and cash equivalents.

On April 23, 2002, we announced that our Board of Directors had authorized a two-for-one stock split on all shares of L-3 Holdings common stock. The stock split entitled all shareholders of record at the close of business on May 6, 2002 to receive one additional share of L-3 Holdings common stock for every share held on that date. The additional shares were distributed to shareholders in the form of a stock dividend on May 20, 2002. Upon completion of the stock spilt, L-3 Holdings had approximately 80 million shares of common stock outstanding.

Anticipated Sources of Cash Flow

Based upon our current level of operations, we believe that our cash from operating activities, together with available borrowings under the new 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, L-3 Holdings' dividends and interest payments for the foreseeable future. There can be no assurance, however, that our business will continue to generate cash flows 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

42

---

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, to make necessary capital expenditures and to make discretionary investments.

Contractual Obligations

The table below presents our contractual obligations at December 31, 2004.

								Year(s) Ending December 31,
Contractual Obligations:				Total				2005				2006 – 2007				2008 – 2009				2010 and thereafter
				(in millions)
Long-term debt(1)				$	2,200.0			$	—			$	—			$	—			$	2,200.0
Non-cancelable operating leases					579.5				115.7				142.1				104.1				217.6

Total				$	3,825.4			$	897.4			$	320.5			$	141.3			$	2,466.2

(1)	Long-term debt includes scheduled principal payments only.

(2)	Represents open purchase orders at December 31, 2004 for amounts expected to be paid for goods or services that are legally binding on us.

(3)	Other long-term liabilities primarily consists of workers compensation, deferred compensation and litigation settlement accruals for the years ending December 31, 2006 and thereafter and also includes pension and postretirement benefit plan contributions that we expect to pay in 2005.

(4)

Our pension and postretirement benefit plan funding policy is generally to contribute in accordance with cost accounting standards that affect government contractors, subject to the Internal Revenue Code and regulations thereon. For 2005, we expect to contribute approximately $70.0 million to our pension plans and $13.0 million to our postretirement benefit plans. Due to the current uncertainty of the amounts used to compute our expected pension and postretirement benefit plan funding, we believe it is not practicable to reasonably estimate such future funding for periods in excess of 1 year.

(5)	Represents additional purchase payments for business acquisitions that are contingent upon the post-aquisition financial performance of the acquired business.

Off Balance Sheet Arrangements

On December 31, 2002, we entered into two real estate lease agreements, as lessee, with a third-party lessor, which expire on December 31, 2005 and are accounted for as operating leases. On or before the lease expiration date, we can exercise options under the lease agreements to either renew the leases, purchase both properties for $28.0 million, or sell both properties on behalf of the lessor (the "Sale Option"). If we elect the Sale Option, we must pay the lessor a residual guarantee amount of $22.7 million for both properties, on or before the lease expiration date, and at the time both properties are sold, we must pay the lessor a supplemental rent equal to the gross sales proceeds in excess of the residual guarantee amount not to exceed $5.3 million.

We have a contract to provide and operate for the U.S. Air Force (USAF) a full-service training facility, including simulator systems adjacent to a USAF base in Oklahoma. We acted as the construction agent on behalf of the third-party owner-lessors for procurement and construction for the simulator systems, which were completed and delivered in August 2002. On December 31, 2002, we, as lessee, entered into an operating lease agreement for a term of 15 years for one of the simulator systems with the owner-lessor. At the end of the lease term, we may elect to purchase the simulator system at fair market value, which can be no less than $2.6 million and no greater than $6.4 million. If we do not elect to purchase the simulator system, then on the date of expiration, we shall pay to the lessor, as additional rent, $2.6 million and return the simulator system to the lessor. The aggregate non-cancelable rental payments

43

---

under this operating lease are $32.5 million, including the additional rent of $2.6 million. On February 27, 2003, we, as lessee, entered into an operating lease agreement for a term of 15 years for the remaining simulation systems with the owner-lessor. At the end of the lease term, we may elect to purchase the simulator systems at fair market value, which can be no less than $4.1 million and no greater than $14.5 million. If we do not elect to purchase the simulator systems, then on the date of expiration, we shall return the simulator systems to the lessor. The aggregate non-cancelable rental payments under this operating lease are $53.3 million.

Derivative Financial Instruments

Included in our derivative financial instruments are foreign currency forward contracts, foreign currency put options and interest rate swap agreements. All of our derivative financial instruments that are sensitive to market risk are entered into for purposes other than trading.

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. At December 31, 2004, there were no outstanding borrowings under our senior credit facilities. The interest rates on the senior subordinated notes are fixed-rate and are not affected by changes in interest rates. Depending on interest rate levels, we may enter into interest rate swap agreements to convert certain of our fixed interest rate debt obligations to variable interest rates, or terminate any existing interest rate swap agreements. The variable interest rate paid by us is equal to (i) the variable rate basis, plus (ii) the variable rate spread. See Note 8 to the audited consolidated financial statements for a detailed table of our interest rate swap agreement that is currently outstanding, and a table that presents the activity for our terminated interest rate swap agreements through December 31, 2004.

Outstanding interest rate swap agreements reduced interest expense by $4.5 million during 2004, compared to $5.5 million during 2003. Interest expense was reduced by $4.2 million for 2004, compared to $3.1 million for 2003 for amortization of deferred gains on terminated interest rate swap agreements. For every basis point (0.01%) that the six-month USD LIBOR interest rate is greater than 4.58%, we will incur an additional $10,000 of interest expense above the fixed interest rate on $100.0 million of senior subordinated notes calculated on a per annum basis until maturity. Conversely, for every basis point that the six-month USD Libor interest rate is less than 4.58%, we will recognize interest income of $10,000 on $100.0 million of senior subordinated notes calculated on a per annum basis until maturity.

When we enter into interest rate swap agreements, we attempt to manage exposure to counterparty credit risk by only entering into agreements with major financial institutions that are expected to be able to fully perform under the terms of such agreements. Cash payments between us and the counterparties are made in accordance with the terms of the interest rate swap agreements. Such payments are recorded as adjustments to interest expense. Additional data on our debt obligations, our applicable borrowing spreads included in the interest rates we pay on borrowings under the senior credit facilities and interest rate swap agreements are provided in Notes 8 and 9 to our audited consolidated financial statements.

Foreign Currency Exchange Risk.    We conduct some of our operations outside the U.S. in functional currencies other than the U.S. dollar. Additionally, some of our U.S. and foreign operations have contracts with customers which are denominated in currencies other than the functional currencies of those operations. To mitigate the risk associated with certain of these contracts denominated in foreign currency we have entered into foreign currency forward contracts and put options. At December 31, 2004, the notional value of foreign currency forward contracts was $126.3 million and the fair value of these contracts was $2.1 million, which represented a liability. There were no foreign currency put options outstanding at December 31, 2004. We account for these contracts as cash flow hedges.

Equity Price Risk.    Our equity investments in common stocks, joint ventures and limited liability corporations are subject to equity price risk, including equity risk. The fair values of our investments are based on quoted market prices for investments which are readily marketable securities, and estimated fair value for nonreadily marketable securities, which is generally equal to historical cost unless such investment has experienced an other-than-temporary impairment. Both the carrying values and estimated fair values of such investments amounted to $30.3 million at the end of 2004.

Backlog and Orders

We define funded backlog as the value of funded orders received from customers, less the amount of sales recognized on those funded orders. We define funded orders as the value of contract awards received from the U.S. Government, for which the U.S. Government has appropriated funds, plus the value of contract awards and orders received from customers other than the U.S. Government. The table below presents our funded backlog, percent of funded backlog at December 31, 2004 expected to be recorded as sales in 2005 and funded orders for each of our reportable segments.

				Funded Backlog at December 31,								Percentage of December 31, 2004 Funded Backlog Expected to be Recorded as Sales in 2005				Funded Orders
Reportable Segment:				2004				2003								2004				2003
Secure Communications & ISR				$	1,351.9			$	1,075.3				85.0	%		$	1,871.3			$	1,544.1
Training, Simulation & Government Services					662.4				591.3				80.4				1,296.7				1,176.3
Aircraft Modernization, O&M and Products					1,231.5				993.1				77.2				2,487.2				1,101.1
Specialized Products					1,512.1				1,233.6				69.1				1,908.5				1,655.9
Consolidated				$	4,757.9			$	3,893.3				77.3	%		$	7,563.7			$	5,477.4

Our funded backlog does not include the full value of our contract awards including those pertaining to multi-year, cost-plus reimbursable contracts, which are generally funded on an annual basis. Funded backlog also excludes the sales value of unexercised contract options that may be exercised by customers under existing contracts and the sales value of purchase orders that we may receive under indefinite quantity contracts or basic ordering agreements.

Research and Development

The following table presents L-3's (i) company-sponsored (independent) research and development costs and (ii) customer-funded research and development costs, which are incurred on revenue arrangements to perform research and development services for customers. See Note 2 to the consolidated financial statements for a discussion of L-3's accounting policies for research and development costs.

				Year Ended December 31,
				2004				2003				2002
Company-Sponsored Research and Development Costs:
U.S. Government Contractor Businesses				$	149.4			$	129.4			$	124.2
Commercial Businesses					71.2				59.2				35.7
Total				$	220.6			$	188.6			$	159.9
Customer-Funded Research and Development Costs				$	689.2			$	573.1			$	480.9

Contingencies

We are engaged in providing products and services under contracts with 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, periodically, 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 by a federal grand jury could result in the suspension 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 we manufacture and provide are reduced and not offset by greater commercial sales or other new programs or products or business acquisitions, there may be a reduction in the volume of contracts or subcontracts awarded to us. We are currently cooperating with the U.S. Government on several investigations, none of which we anticipate will have a material adverse effect on our consolidated financial position, results of operations or cash flows.

We continually assess our obligations with respect to applicable environmental protection laws. While it is difficult to determine the timing and ultimate cost that we will incur to comply with these laws, based upon available internal and external assessments, with respect to those environmental loss contingencies of which we are aware, we believe 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 our consolidated financial position, results of operations or cash flows. Also, we have been periodically subject to litigation, claims or assessments and various contingent liabilities incidental to our business. We accrue for these contingencies when it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated.

In connection with the IS acquisition we assumed responsibility for implementing certain corrective actions required under federal law to remediate the Greenville, Texas site location, and to pay a portion of those remediation costs. The hazardous substances requiring remediation have been substantially characterized, and the remediation system has been partially implemented. We have estimated that our share of the remediation cost will not exceed $2.5 million, and will be incurred over a period of 25 years. We have established adequate reserves for these costs.

With respect to those investigative actions, items of litigation, claims or assessments of which we are aware, we are of the opinion that the likelihood of loss is less than probable that, after taking into account certain provisions for these matters, the ultimate resolution of any such investigative actions, items of litigation, claims or assessments will have a material adverse effect on our consolidated financial position, results of operations or cash flows. For a description of our legal proceedings, see Item 3 — Legal Proceedings.

Recently Issued Accounting Standards

In December of 2004, the FASB revised its FASB Statement No. 123, Accounting for Stock Based Compensation (SFAS 123) and renamed it FASB Statement No. 123, Share-Based Payment (SFAS 123R). SFAS 123R requires that compensation expense relating to share-based payment transactions be recognized in financial statements at estimated fair value. The scope of SFAS 123R includes a wide range of share-based compensation arrangements, including share options, restricted share plans, performance-based awards, share appreciation rights and employee share purchase plans. This standard replaces SFAS 123 and supersedes APB Opinion No. 25, Accounting for Stock Issued to Employees. We are required to adopt the provisions of SFAS 123R for the interim period ending September 30, 2005. We are currently assessing the provisions of SFAS 123R. We previously elected not to adopt the fair value based method of accounting for stock-based employee compensation as permitted by SFAS 123. The adoption of SFAS 123R will result in the recording of non-cash compensation expenses, which we do not currently recognize in our financial statements. In accordance with SFAS 123, we disclose pro forma net income and earnings per share adjusted for non-cash compensation expense arising from the estimated fair value of share-based payment transactions. For a further discussion of our accounting for stock-based employee compensation and disclosure of our pro forma historical net income and earnings per share, see Note 2 to the audited consolidated financial statements.

The U.S. enacted the American Jobs Creation Act of 2004 (the American Jobs Creation Act) in October 2004, which contains many provisions affecting corporate taxation. The American Jobs Creation Act phases out the extraterritorial income (ETI) exclusion benefit for export sales and phases in a new tax deduction for income from qualified domestic production activities (QPA) over a transition period beginning in 2005. In December 2004, the FASB issued FASB Staff Position 109-1 (FSP 109-1), which provides guidance that the QPA deduction should be treated as a special income tax deduction as described in SFAS 109. As such, QPA has no impact on our deferred tax assets or liabilities existing as of the enactment date. Rather, the QPA deduction will be reported in the period that the deductions are claimed on our income tax returns. While we have not completed our evaluation of the net impact of the American Jobs Creation Act, we believe that the benefit from the phase-in of the QPA deduction will be substantially equivalent to the lost benefit from the phase-out of the ETI exclusion in 2005. We do not expect that the other provisions included in the American Jobs Creation Act will have a significant impact on our financial position, results of operations or cash flows.

On September 30, 2004, the EITF reached a consensus on issue No. 04-8, The Effect of Contingently Convertible Debt on Diluted Earnings per Share. See "Results of Operations" above for a description of EITF No. 04-8 and its impact on our results of operations.

On December 8, 2003, President Bush signed the Medicare Prescription Drug, Improvement and Modernization Act of 2003 (the Act). This Act introduces a federal subsidy to employers who sponsor retiree health care benefit plans that provide a benefit that is at least actuarially equivalent to Medicare Part D. On January 21, 2005, the Centers for Medicare and Medical Services (CMS) released final regulations implementing the Act. We have not determined the possible effect of the final regulations on our accumulated postretirement benefit obligation. In May of 2004, the FASB issued FASB Staff Position 106-2, Accounting and Disclosure Requirements Related to the Medicare Prescription Drug, Improvement and Modernization Act of 2003 (FSP 106-2). FSP 106-2 provides guidance on the accounting for the effects of the Act and requires certain disclosures regarding the effect of the federal subsidy provided by the Act. In accordance with FSP 106-2 we have accounted for the effect of the Act on a preliminary basis and disclosed the effect in Note 16 of our audited consolidated financial statements.

Inflation

The effect of inflation on our sales and earnings has not been significant. Although a majority of our sales are made under long-term contracts (revenue arrangements), the selling prices of such contracts, established for deliveries in the future, generally reflect estimated costs to be incurred in these future periods. In addition, some of our contracts provide for price adjustments through cost escalation clauses.

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;

•	the extensive legal and regulatory requirements surrounding our contracts with the U.S. Government and the results of any investigation of our contracts undertaken by the U.S. Government.

•	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;

•	our ability to continue to retain and train our existing employees and to recruit and hire new qualified and skilled employees;

•	our collective bargaining agreements and our ability to favorably resolve labor disputes should they arise;

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

47

---

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

•	our extensive use of fixed-price type contracts as compared to cost-reimbursable type and time-and-material type contracts;

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

•	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, including the Kalitta Air and OSI Systems matters and various other market, competition and industry factors, 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 and such differences could be material. 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 7A.    Quantitative and Qualitative Disclosures about Market Risk

Data regarding quantitative and qualitative disclosures related to our market risk sensitive financial instruments are presented in (i) "Management's Discussion and Analysis of Results of Operations and Financial Condition — Liquidity and Capital Resources — Derivative Financial Instruments" included herein under Item 7 and (ii) Note 9 to the consolidated financial statements.

Item 8.    Financial Statements and Supplementary Data

See Financial Statements beginning on page F-1.

Item 9.    Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

Not applicable.

Item 9A.    Controls and Procedures

Conclusions Regarding Effectiveness of Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our 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 our management, including our Chairman and Chief Executive Officer and our 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. Our management, with the participation of our Chairman and Chief Executive Officer and our Chief Financial Officer, has evaluated the effectiveness of the design and operation of our disclosure controls and procedures as of December 31, 2004. Based upon that evaluation and subject to the foregoing, our Chairman and Chief Executive Officer and our Chief Financial Officer concluded that the design and operation of our 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 our internal control over financial reporting that occurred during the quarter ended December 31, 2004 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Management's Report on Internal Control Over Financial Reporting

As required by the SEC rules and regulations for the implementation of Section 404 of the Sarbanes-Oxley Act, our management is responsible for establishing and maintaining adequate internal control over financial reporting. L-3's internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of our consolidated financial statements for external reporting purposes in accordance with generally accepted accounting principles. Our internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of L-3, (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of consolidated financial statements in accordance with generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with authorizations of L-3's management and directors, and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the consolidated financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements in our consolidated financial statements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree or compliance with the policies or procedures may deteriorate.

Management assessed the effectiveness of L-3 Holdings' and L-3 Communications' internal control over financial reporting as of December 31, 2004. In making these assessments, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control — Integrated Framework. Based on our assessments and those criteria, management determined that L-3 Holdings and L-3 Communications maintained effective internal control over financial reporting as of December 31, 2004.

Our independent registered public accounting firm has audited and issued their report on management's assessments of the effectiveness of our internal control over financial reporting as of December 31, 2004. See page F-2 to our consolidated financial statements for their report.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of
    L-3 Communications Holdings, Inc. and L-3 Communications Corporation:

We have completed an integrated audit of the 2004 consolidated financial statements and of the internal control over financial reporting as of December 31, 2004 for each of L-3 Communications Holdings, Inc. ("L-3 Holdings") and L-3 Communications Corporation ("L-3 Communications") and subsidiaries' (collectively, the "Company") and audits of the December 31, 2003 and 2002 consolidated financial statements of L-3 Holdings and L-3 Communications in accordance with the standards of the Public Company Accounting Oversight Board (United States). Our opinions, based on our audits, are presented below.

Consolidated financial statements

In our opinion, the consolidated financial statements listed in the index appearing under Item 15(a)(1) present fairly, in all material respects, the financial position of L-3 Holdings and L-3 Communications and subsidiaries at December 31, 2004 and 2003, and the results of each of their operations and each of their cash flows for each of the three years in the period ended December 31, 2004 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 the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit of financial statements 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 opinions.

As indicated in Note 12 to the consolidated financial statements, in 2004 the Company adopted the provisions of Emerging Issues Task Force Issue No. 04-8, The Effect of Contingently Convertible Debt on Diluted Earnings Per Share. As indicated in Note 5 to the consolidated financial statements, in 2002 the Company adopted the provisions of Statement of Financial Accounting Standards No. 142, Goodwill and Other Intangible Assets.

Internal control over financial reporting

Also, in our opinion, management's assessments, included in Management's Report on Internal Control Over Financial Reporting appearing under Item 9A, that L-3 Holdings and L-3 Communications maintained effective internal control over financial reporting as of December 31, 2004 based on criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), are fairly stated, in all material respects, based on those criteria. Furthermore, in our opinion, L-3 Holdings and L-3 Communications maintained, in all material respects, effective internal control over financial reporting as of December 31, 2004, based on criteria established in Internal Control – Integrated Framework issued by the COSO. The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessments of the effectiveness of internal control over financial reporting. Our responsibility is to express opinions on management's assessments and on the effectiveness of L-3 Holdings' and L-3 Communications' internal control over financial reporting based on our audits. We conducted our audits of internal control over financial reporting in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. An audit of internal control over financial reporting includes obtaining an understanding of internal control over financial reporting, evaluating management's assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we consider necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

2.    Summary of Significant Accounting Policies

Basis of Presentation:    The accompanying financial statements comprise the consolidated financial statements of L-3 Holdings and L-3 Communications. L-3 Holdings' only asset is its investment in the common stock of L-3 Communications, its wholly-owned subsidiary. L-3 Holdings' obligations of 5¼% Convertible Senior Subordinated Notes due 2009 and 4% Senior Subordinated Convertible Contingent Debt Securities due 2011 (CODES) were converted into L-3 Holdings' common stock during 2004. L-3 Holdings has also guaranteed the borrowings under the senior credit facilities of L-3 Communications. L-3 Holdings' obligations have been jointly, severally, fully and unconditionally guaranteed by L-3 Communications and certain of its domestic subsidiaries, and accordingly, such debt has been reflected as debt of L-3 Communications in its consolidated financial statements in accordance with the U.S. Securities and

F-8

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

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

Exchange Commission's (SEC) Staff Accounting Bulletin (SAB) No. 54. In addition, all issuances of and conversions into L-3 Holdings' equity securities, including grants of stock options and restricted stock by L-3 Holdings to employees of L-3 Communications, have been reflected in the consolidated financial statements of L-3 Communications. As a result, the consolidated financial positions, results of operations and cash flows of L-3 Holdings and L-3 Communications are substantially the same. See Note 20 for additional information.

Principles Of Consolidation:    The consolidated financial statements of the Company include all wholly-owned and significant majority-owned subsidiaries. All significant intercompany transactions are eliminated in consolidation. Investments in equity securities, joint ventures and limited liability corporations over which the Company has significant influence but does not have voting control are accounted for by the equity method. Investments over which the Company does not have significant influence and do not have readily determinable fair values are accounted for using the cost method.

Sales And Costs And Expenses Presentation:    The Company presents its sales and costs and expenses in two categories on the statement of operations, "Contracts, primarily U.S. Government" and "Commercial, primarily products." Sales and costs and expenses for the Company's businesses that are primarily U.S. Government contractors are presented as "Contracts, primarily U.S. Government." The sales for the Company's U.S. Government contractor businesses are transacted using written revenue arrangements, or contracts, which primarily require the Company to design, develop, manufacture, modify, upgrade, test and integrate complex aerospace and electronic equipment, and to provide related engineering and technical services according to the buyer's specifications. Such buyers are predominantly the U.S. Department of Defense and other agencies of the U.S. Government, allied foreign government ministries of defense and defense prime contractors. These contracts are covered by the American Institute of Certified Public Accountants (AICPA) Statement of Position 81-1, Accounting for Performance of Construction — Type and certain Production-Type Contracts (SOP 81-1), Accounting Research Bulletin No. 43, Chapter 11, Section A, Government Contracts, Cost-Plus-Fixed Fee Contracts (ARB 43) and Accounting Research Bulletin No. 45, Long-Term Construction Type Contracts (ARB 45). Sales reported under "Contracts, primarily U.S. Government" also include certain sales from contracts with domestic and foreign commercial customers, which also are within the scope of SOP 81-1 and ARB 45. Additionally, certain fixed price contacts require the Company to perform services that are not related to the production of tangible assets which are not covered by SOP- 81-1, and these sales are recognized in accordance with the SEC's SAB No. 104, Revenue Recognition (SAB 104). Sales and costs and expenses for the Company's businesses whose customers are primarily commercial business enterprises are presented as "Commercial, primarily products". Most of these sales are recognized in accordance with SAB 104, and substantially all of the related revenue arrangements are not within the scope of SOP 81-1, ARB 43 or ARB 45. The Company's commercial businesses are substantially comprised of Aviation Communication & Surveillance Systems (ACSS), Aviation Recorders, Microwave Components, Security & Detection Systems and Avionics Systems.

Cash and Cash Equivalents:    Cash equivalents consist of highly liquid investments with a maturity of three months or less at time of purchase.

Revenue Recognition:    The substantial majority of the Company's direct and indirect sales to the U.S. Government and certain of the Company's sales to allied foreign governments and commercial customers are within the scope of SOP 81-1, ARB 43 and ARB 45 and sales and profits on them are recognized using percentage-of-completion methods of accounting. Sales and profits on fixed-price production contracts under which units are produced and delivered in a continuous or sequential process are recorded as units are delivered based on their contractual selling prices (the "units-of-delivery" method). Sales and profits on fixed-price production contracts under which units are not produced and delivered in a continuous or sequential process, or under which a relatively few number of units are

F-9

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

produced, are recorded based on the ratio of total actual incurred costs to date to the total estimated costs for each contract (the "cost-to-cost" method). Under the percentage-of-completion methods of accounting, a single estimated total profit margin is used to recognize profit for each contract over its entire period of performance, which can exceed one year. Amounts representing contract change orders or claims are included in sales and estimated contract values only when they can be reliably estimated and their realization is reasonably assured. Losses on contracts are recognized in the period in which they are determined. The impact of revisions of contract estimates, which may result from contract modifications, performance or other reasons, are recognized on a cumulative catch-up basis in the period in which the revisions are made. Sales and profits on fixed-price contracts that require us to perform services that are not related to production of tangible assets are recognized in accordance with SAB 104.

Sales and profits on cost-reimbursable type contracts that are within the scope of ARB 43 in addition to SOP 81-1 are recognized as allowable costs are incurred on the contract and become billable to the customer, at an amount equal to the allowable costs plus the estimated profit on those costs. The estimated profit on a cost-reimbursable contract is generally fixed or variable based on the contract fee arrangement. Incentive and award fees on these contracts are recorded as revenue when the conditions under which they are earned are reasonably assured of being met.

Sales and profits on time and material type contracts are recognized on the basis of direct labor hours expended at fixed hourly rates plus the cost of materials and other specified costs.

Sales on arrangements that are not within the scope of SOP 81-1, ARB 43 or ARB 45 are recognized in accordance with SAB 104. Sales are recognized when there is persuasive evidence of an arrangement, delivery has occurred or services have been performed, the selling price to the buyer is fixed or determinable and collectibility is reasonably assured. For fixed-price contracts that are not within the scope of SOP 81-1, which the performance of services are not related to production of tangible assets and do not contain measurable units of work performed, sales are recognized on straight-line basis over the contractual service period. For fixed-price service contracts that are not within the scope of SOP 81-1, and contain measurable units of work performed, sales are recognized when the units of work are completed.

Contracts in Process:    Contracts in process include receivables and inventories for contracts that are within the scope of SOP 81-1, ARB 43 and ARB 45, as well as receivables and inventories related to other contractual arrangements. Billed Receivables represent the uncollected portion of amounts recorded as sales and billed to customers for all revenue arrangements, net of allowances for uncollectible accounts. Unbilled Contract Receivables represent accumulated incurred costs and earned profits or losses on contracts in process that have been recorded as sales, primarily using the cost-to-cost percentage of completion method, which have not yet been billed to customers. Inventoried Contract Costs represent incurred costs on contracts in process that have not yet been recognized as costs and expenses because the related sales, which are primarily recorded using the units-of-delivery percentage of completion method, have not been recognized. Contract costs include direct costs and indirect costs, including overhead costs. As discussed below in Note 4, the Company's inventoried contract costs for U.S. Government contracts, and contracts with prime contractors or subcontractors of the U.S. Government include allocated general and administrative costs, independent research and development costs and bid and proposal costs. Contracts in Process contain amounts relating to contracts and programs with long performance cycles, a portion of which may not be realized within one year. For contracts in a loss position, the unrecoverable costs expected to be incurred in future periods are recorded in Estimated Costs in Excess of Estimated Contract Value to Complete Contracts in Process, which is a component of Other Current Liabilities. Under the terms of certain revenue arrangements (contracts) with the U.S. Government, the Company may receive progress payments as it incurs costs, or milestone payments as it performs work. The U.S. Government has a security interest in the Unbilled Contract Receivables and Inventoried Contract Costs to which progress payments have been applied, and such progress payments are reflected as a reduction

(Dollars in thousands, except per share data)

of the related Unbilled Contract Receivables and Inventoried Contract Costs. Milestone payments that have been received in excess of contract costs and estimated profits on revenue arrangements are reported on the Company's balance sheet as a component of current liabilities as Billings in Excess of Costs and Estimated Profits. Customer Advances are reported in the balance sheet as a component of current liabilities.

Inventories other than Inventoried Contract Costs are stated at the lower of cost or market primarily using the average cost method.

The Company values its acquired contracts in process on the date of acquisition at contract value less the Company's estimated costs to complete the contract and a reasonable profit allowance on the Company's completion effort commensurate with the profit margin that the Company earns on similar contracts.

Derivative Financial Instruments:    The Company has entered into interest rate swap agreements and foreign currency forward contracts. Derivative financial instruments also include embedded derivatives. The Company's interest rate swap agreements have been accounted for as fair value hedges. The difference between the variable interest rates paid on the interest rate swap agreements and the fixed interest rate on the debt instrument underlying the swap agreements is recorded as increases or decreases to interest expense. Upon termination of an interest rate swap agreement, the cash received or paid that relates to the future value of the swap agreements at the termination date is a deferred gain or loss, which is recognized as a decrease or increase to interest expense over the remaining term of the underlying debt instrument. Foreign currency forward contracts are accounted for as cash flow hedges. Gains and losses on foreign currency forward contracts are recognized in earnings when the underlying hedged transaction within contracts in process affects earnings. The embedded derivatives related to the issuance of the Company's debt are recorded at fair value with changes reflected in the statement of operations.

Property, Plant and Equipment:    Property, plant and equipment are stated at cost, less accumulated depreciation. Depreciation is computed by applying principally the straight-line method to the estimated useful lives of the related assets. Useful lives range substantially from 10 to 40 years for buildings and improvements and 3 to 10 years for machinery, equipment, furniture and fixtures. Leasehold improvements are amortized over the shorter of the lease term or the estimated useful life of the improvements. When property or equipment is retired or otherwise disposed of, the net book value of the asset is removed from the Company's balance sheet and the net gain or loss is included in the determination of operating income.

Debt Issue Costs:    Costs to issue debt are capitalized and deferred when incurred, and subsequently amortized to interest expense over the term of the related debt using a method that approximates the effective interest method.

Identifiable Intangible Assets:    Identifiable intangible assets represent assets acquired as part of the Company's business acquisitions and include customer relationships, technology and non-compete agreements. Effective January 1, 2002, the initial measurement of these intangible assets has been based on their fair values. The values assigned to acquired identifiable intangible assets are determined, as of the date of acquisition, based on estimates and judgements regarding expectations for the estimated future after-tax cash flows from those assets over their lives, including the probability of expected future contract renewals and sales, less a cost-of-capital charge, all of which is discounted to present value. Identifiable intangible assets are amortized over their estimated useful lives as the economic benefits are consumed, ranging from 5 to 20 years.

Goodwill:    Effective January 1, 2002, the Company accounts for goodwill in accordance with Statement of Financial Accounting Standards (SFAS) No. 142, Goodwill and other Intangible Assets. The

F-11

(Dollars in thousands, except per share data)

carrying value of goodwill and indefinite lived identifiable intangible assets are not amortized, but are tested for impairment based on their estimated fair values using discounted cash flows valuation at the beginning of each year, and whenever events or changes in circumstances indicate that the carrying amount of these assets may not be recoverable. Prior to January 1, 2002, goodwill was amortized on a straight-line basis over periods ranging from 15 to 40 years except for goodwill related to acquisitions consummated after June 30, 2001. Prior to the adoption of SFAS 142, the Company evaluated the carrying amount of goodwill by reference to current and estimated profitability and undiscounted cash flows.

Income Taxes:    The Company provides for income taxes using the liability method. Deferred income tax assets and liabilities reflect tax carryforwards and the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting and income tax purposes, as determined under enacted tax laws and rates. The effect of changes in tax laws or rates is accounted for in the period of enactment. Valuation allowances for deferred tax assets are provided when it is more likely than not that the assets will not be realized, considering, when appropriate, tax planning strategies.

Research and Development:    Independent research and development costs sponsored by the Company include bid and proposal costs, and relate to both U.S. Government products and services and those for commercial and foreign customers. The independent research and development (IRAD) and bid and proposal costs (B&P) for the Company's businesses that are U.S. Government contractors are recoverable indirect contract costs that are allocated to our U.S. Government contracts in accordance with U.S. Government procurement regulations, and are specifically excluded from the scope of SFAS No. 2, Accounting for Research and Development Costs (SFAS 2). In accordance with SOP 81-1 and the AICPA Audit and Accounting Guide, Audits of Federal Government Contractors, the Company includes IRAD and B&P costs allocated to U.S. Government contracts in inventoried contract costs, and charges them to costs of sales when the related contract sales are recognized as revenue. Research and development costs for the Company's businesses that are not U.S. Government contractors are expensed as incurred in accordance with SFAS 2.

Customer-funded research and development costs are incurred pursuant to contracts (revenue arrangements) to perform research and development activities according to customer specifications. These costs are not accounted for as research and development expenses in accordance with SFAS 2, and are also not indirect contract costs. Instead, these costs are direct contract costs and are expensed when the corresponding revenue is recognized, which is generally as the research and development services are performed. Customer-funded research and development costs are substantially all incurred under cost-reimbursable type contracts with the U.S. Government.

Computer Software Costs:    The Company's software development costs for computer software products to be sold, leased or marketed that are incurred after establishing technological feasibility for the computer software products are capitalized as other assets and amortized on a product by product basis using the amount that is the greater of the straight-line method over the useful life or the ratio of current revenues to total estimated revenues in accordance with SFAS No. 86, Accounting for the Costs of Computer Software to Be Sold, Leased or Otherwise Marketed. Substantially all of the capitalized software development costs pertain to products of the Company's commercial businesses. Capitalized software development costs, net of accumulated amortization, was $34,557 at December 31, 2004 and $29,990 at December 31, 2003, and is included in Other Assets on the consolidated balance sheets. Amortization expense for capitalized software development costs was $7,760 for 2004, $6,917 for 2003 and $5,209 for 2002.

Stock-Based Compensation:    The Company accounts for employee stock-based compensation under the recognition and measurement principles of Accounting Principles Board (APB) Opinion No. 25, Accounting for Stock Issued to Employees. Compensation expense for employee stock-based compensation is recognized in income based on the excess, if any, of the fair value of L-3 Holdings' stock at the grant

F-12

AND L-3 COMMUNICATIONS CORPORATION

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

date of the award or other measurement date over the amount an employee must pay to acquire the stock. When the exercise price for stock-based compensation arrangements granted to employees equals or exceeds the fair value of the L-3 Holdings common stock at the date of grant, the Company does not recognize compensation expense. The Company elected not to adopt the fair value based method of accounting for stock-based employee compensation as permitted by the Financial Accounting Standards Board's (FASB) Statement of Financial Accounting Standards (SFAS) No. 123, Accounting for Stock-Based Compensation (SFAS 123), as amended by SFAS No. 148, Accounting for Stock-Based Compensation-Transition and Disclosure-an amendment of SFAS No. 123. Had the Company adopted the fair value based method provisions of SFAS 123 for all of its stock-based compensation, it would have recorded a non-cash expense for the estimated fair value of the stock-based compensation arrangements that the Company has granted to its employees amortized over the vesting period of the grants. Stock-based employee compensation is a non-cash expense, because the Company settles its stock-based compensation obligations by issuing shares of common stock instead of settling such obligations with cash payments. All of the stock options granted to employees by the Company are non-qualified stock options under U.S. income tax regulations. As discussed below in Recently Issued Accounting Standards, SFAS 123 was revised in December 2004.

The table below presents the "as reported" net income and L-3 Holdings earnings per share (EPS) and the "pro forma" net income and L-3 Holdings EPS that the Company would have reported if the Company had elected to recognize non-cash compensation expense in accordance with the fair value based method of accounting of SFAS 123.

				Year Ended December 31,
				2004				2003				2002
Net income:
As reported				$	381,880			$	277,640			$	178,097
Pro forma					358,776				259,997				160,079
L-3 Holdings Basic EPS:

Pro forma					3.13				2.47				1.72

The assumptions used to calculate the fair value of stock options at their grant dates are presented in Note 14.

Product Warranties:    Product warranty costs are accrued when revenue is recognized for the covered products. Product warranty expense is recognized based on the terms of the product warranty and the related estimated costs. Accrued warranty costs are reduced as product warranty costs are incurred.

Use of Estimates:    The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of sales and costs and expenses during the reporting period. The most significant of these estimates and assumptions relate to contract revenue, profit and loss recognition, market values for inventories reported at lower of cost or market, pension and postretirement benefit obligations, recoverability and valuation of recorded amounts of long-lived assets, identifiable intangible assets, goodwill, income taxes, including the valuations of

deferred tax assets, litigation reserves and environmental obligations. Changes in estimates are reflected in the periods during which they become known. Actual amounts will differ from these estimates.

Recently Issued Accounting Standards:    In December of 2004, the FASB revised its FASB Statement No. 123, Accounting for Stock Based Compensation (SFAS 123) and renamed it FASB Statement No. 123, Share-Based Payment (SFAS 123R). SFAS 123R requires that compensation expense relating to share-based payment transactions be recognized in financial statements at estimated fair value. The scope of SFAS 123R includes a wide range of share-based compensation arrangements, including share options, restricted share plans, performance-based awards, share appreciation rights, and employee share purchase plans. This standard replaces SFAS 123 and supersedes APB Opinion No. 25, Accounting for Stock Issued to Employees. The Company is required to adopt the provisions of SFAS 123R for the interim period ending September 30, 2005. The Company is currently assessing the provisions of SFAS 123R. The Company previously elected not to adopt the fair value based method of accounting for stock-based employee compensation as permitted by SFAS 123. The adoption of SFAS 123R will result in the recording of non-cash compensation expenses, which is not currently recognized in the Company's financial statements. In accordance with SFAS 123, the Company discloses pro forma net income and earnings per share adjusted for non-cash compensation expense arising from the estimated fair value of share-based payment transactions. See "Stock-Based Compensation" above for a further discussion of the Company's accounting for stock-based employee compensation and disclosure of pro forma historical net income and earnings per share.

The U.S. enacted the American Jobs Creation Act of 2004 (the American Jobs Creation Act) in October 2004 which contains many provisions affecting corporate taxation. The American Jobs Creation Act phases out the extraterritorial income (ETI) exclusion benefit for export sales and phases in a new tax deduction for income from qualified domestic production activities (QPA) over a transition period beginning in 2005. In December 2004, the FASB issued FASB Staff Position 109-1 (FSP 109-1), which provides guidance that the QPA deduction should be treated as a special income tax deduction as described in SFAS 109. As such, QPA has no impact on the Company's deferred tax assets or liabilities existing as of the enactment date. Rather, the QPA deduction will be reported in the period that the deductions are claimed on the Company's income tax returns. While the Company has not completed its evaluation of the net impact of the American Jobs Creation Act, the Company believes that the benefit from the phase-in of the OPA deduction will be substantially equivalent to the lost benefit from the phase-out of the ETI exclusion in 2005. The Company does not expect that the other provisions included in the American Jobs Creation Act will have a significant impact on the Company's financial position, results of operations or cash flows.

On September 30, 2004, the EITF reached a consensus on issue No. 04-8, The Effect of Contingently, Convertible Debt on Diluted Earnings per Share. See Note 12 for a description of EITF No. 04-8 and its impact on the Company's results of operations.

On December 8, 2003, President Bush signed the Medicare Prescription Drug, Improvement and Modernization Act of 2003 (the Act). This Act introduces a federal subsidy to employers who sponsor retiree health care benefit plans that provide a benefit that is at least actuarially equivalent to Medicare Part D. On January 21, 2005, the Centers for Medicare and Medical Services (CMS) released final regulations implementing the Act. The Company has not determined the possible effect of the final regulations on its accumulated postretirement benefit obligation. In May of 2004, the FASB issued FASB Staff Position 106-2, Accounting and Disclosure Requirements Related to the Medicare Prescription Drug, Improvement and Modernization Act of 2003 (FSP 106-2). FSP 106-2 provides guidance on the accounting for the effects of the Act and requires certain disclosures regarding the effect of the federal subsidy

provided by the Act. In accordance with FSP 106-2 the Company has accounted for the effect of the Act on a preliminary basis and disclosed the effect in Note 16 of these audited consolidated financial statements.

Reclassifications:    Effective January 1, 2004, the Company combined its explosives detection systems (EDS) business into L-3 Security and Detection Systems, its IMC business into L-3 Government Services, Inc., the EMP business into its ESSCO business and the Apcom business into its Communication Systems-East business (2004 Business Realignments). As a result of the 2004 Business Realignments, reclassifications between "Contracts, primarily U.S. Government" and "Commercial, primarily products" have been made to the prior period sales and operating income amounts, however, since EDS was primarily a U.S. Government contracting business prior to 2003, the sales and operating income for EDS were not reclassified for 2002 and 2001. Specifically, $96,456 of 2003 sales, $9,070 of 2002 sales, $26,293 of 2003 operating income and $6,149 of 2002 operating loss was reclassified from "Contracts, primarily U.S. Government" to "Commercial, primarily products." Additionally, $30,645 of 2003 sales, $9,239 of 2002 sales, $2,126 of 2003 operating income and $7,432 of 2002 operating loss was reclassified from "Commercial, primarily products" to "Contracts, primarily U.S. Government." The 2004 Business Realignments and related reclassifications did not result in any changes to the Company's consolidated results of operations, financial position or cash flow.

    2002 Business Acquisitions

Aircraft Integration Systems.    On March 8, 2002, the Company acquired the assets of Aircraft Integration Systems (AIS), a division of Raytheon Company (Raytheon), for approximately $1,148,700 in cash, which includes $1,130,000 for the original contract purchase price, and an increase to the contract purchase price of approximately $18,700 related to additional net assets received at closing, plus acquisition costs. Following the acquisition, the Company changed AIS's name to L-3 Communications Integrated Systems (IS). The purchase price is subject to adjustment based on the IS closing date net tangible book value, as defined in the asset purchase agreement. Based on the purchase price allocation for IS, the goodwill recognized was $765,879, of which $514,728 is expected to be deductible for income tax purposes. Goodwill of $520,798 was assigned to the Secure Communications & ISR segment and $245,081 was assigned to the Aircraft Modernization, O&M and Products segment. The Company acquired IS because it is a long-standing supplier of critical communication and signal intelligence and unique sensor systems for special customers within the U.S. Government.

The Company is continuing its discussions with Raytheon regarding the adjustment of the purchase price for the acquisition of AIS. The AIS purchase price submitted by Raytheon to the Company amounted to approximately $1,163,000. The Company believes that, in accordance with the terms of the AIS asset purchase agreement concerning the closing date balance sheet, the purchase price for AIS submitted by Raytheon should be reduced by $100,000 to $1,063,000. In accordance with the asset purchase agreement, the Company and Raytheon are in the formal process of settling the disagreement and engaging a neutral accountant to arbitrate the final purchase price. Any amount received by the Company for a reduction to the AIS purchase price will be recorded as a reduction to goodwill.

During 2002, in separate transactions, the Company also acquired ten businesses for an aggregate consideration of $572,735, plus acquisition costs. Based on the final purchase price allocations, the goodwill recognized for the business acquisitions was $412,237, of which $76,193 is expected to be deductible for income tax purposes. Goodwill of $36,435 was assigned to the Secure Communications & ISR segment, $110,376 was assigned to the Training, Simulation & Government Services segment and $265,426 was assigned to the Specialized Products segment.

(Dollars in thousands, except per share data)

Substantially all of the acquisitions were initially financed with cash on hand or borrowings under the Company's bank credit facilities.

All of the business acquisitions are included in the Company's results of operations from their respective effective dates of acquisition. The assets and liabilities recorded in connection with the purchase price allocations for the acquisitions of Beamhit, Brashear, AVISYS, GEDD, Bay Metals Infrared Products, Cincinnati Electronics, LES, D.P. Associates and BAI, all of which were acquired in 2004, are based upon preliminary estimates of fair values for contracts in process, inventories, estimated costs in excess of estimated contract value to complete contracts in process in a loss position, identifiable intangibles, goodwill, plant and equipment, and deferred income taxes. Actual adjustments will be based on the final purchase prices, including the payment of contingent consideration and final appraisals and other analyses of fair values, which are in process. The Company expects to complete the preliminary purchase price allocations in 2005. The Company does not expect the differences between the preliminary and final purchase price allocations for these acquisitions to be material.

    Unaudited Pro Forma Statement of Operations Data

Assuming the business acquisitions the Company completed during 2004 occurred on January 1, 2004, the unaudited pro forma sales, net income and diluted earnings per share would have been approximately $7,184,700, $381,100 and $3.32, respectively, for the year ended December 31, 2004.

Assuming the business acquisitions the Company completed during 2004 and 2003 occurred on January 1, 2003, the unaudited pro forma sales, net income and diluted earnings per share would have been approximately $6,160,800, $291,200 and $2.74, respectively, for the year ended December 31, 2003.

Assuming the business acquisitions the Company completed during 2003 and 2002 occurred on January 1, 2002, the unaudited pro forma sales, income before cumulative effect of a change in accounting principle, net income and diluted earnings per share would have been approximately $5,474,500, $198,500, $174,100 and $1.74, respectively, for the year ended December 31, 2002.

The pro forma results disclosed in the preceding paragraphs are based on various assumptions and are not necessarily indicative of the results of operations that would have occurred had the Company completed the acquisitions on January 1, 2002, January 1, 2003 and January 1, 2004.

    Business Acquisitions Completed After the Balance Sheet Date

On February 3, 2005, the Company acquired substantially all of the Marine Controls division of CAE. The remaining business operations of the Marine Controls division will be acquired following the receipt of required approvals. On February 25, 2005, the Company acquired the Propulsion Systems business unit of General Dynamics. On February 28, 2005, the Company acquired the Electron Dynamic Devices business of the Boeing Company. The aggregate purchase price paid in cash for these business acquisitions was $471,807.

4.    Contracts in Process

The components of contracts in process are presented in the table below. The unbilled contract receivables, inventoried contract costs and unliquidated progress payments are principally related to contracts with the U.S. Government and prime contractors or subcontractors of the U.S. Government.

				December 31,
				2004				2003
Billed receivables, less allowances of $16,541 and $25,221				$	781,931			$	637,254
Unbilled contract receivables					810,720				676,604
Less: unliquidated progress payments					(179,276	)			(193,672	)
Unbilled contract receivables, net					631,444				482,932
Inventoried contract costs, gross					432,741				353,247
Less: unliquidated progress payments					(50,927	)			(17,624	)
Inventoried contract costs, net					381,814				335,623
Inventories at lower of cost or market					183,838				159,539
Total contracts in process				$	1,979,027			$	1,615,348

Unbilled Contract Receivables.    Unbilled contract receivables represent accumulated incurred costs and earned profits on contracts that have been recorded as sales, which have not yet been billed to customers. The majority of unbilled contract receivables arise from the cost-to-cost percentage-of-completion (POC) method, which is used to record sales on certain fixed-price contracts as costs are incurred at amounts equal to the ratio of cumulative costs incurred to total estimated costs at completion, multiplied by the total estimated contract revenue. Unbilled contract receivables from fixed price-type contracts are converted to billed receivables when amounts are invoiced to customers according to contractual billing terms, which generally occur when deliveries or other performance milestones are completed. To a lesser extent, unbilled contract receivables also arise from cost reimbursable-type contracts and time & material-type contracts, for revenue amounts that have not been billed by the end of the accounting period due to the timing of preparation of invoices for customers. The Company believes that approximately 89% of the unbilled contract receivables at December 31, 2004 will be billed and collected within one year.

Unliquidated Progress Payments.    Unliquidated progress payments arise from fixed price-type contracts with the U.S. Government that contain progress payment clauses, and represent progress payment invoices which have been collected in cash, but have not yet been liquidated. Progress payment invoices are billed to the customer as contract costs are incurred at an amount generally equal to 75% to 80% of incurred costs. Unliquidated progress payments are liquidated as deliveries or other contract performance milestones are completed, at an amount equal to a percentage of the contract sales price for the items delivered or work performed, based on a contractual liquidation rate. Therefore, unliquidated progress payments are a contra asset account, and are classified against unbilled contract receivables if revenue for the underlying contract is recorded using the cost-to-cost POC method, and against inventoried contract costs if revenue is recorded using the units-of-delivery POC method.

Inventoried Contract Costs.    In accordance with SOP 81-1 and the AICPA Audit and Accounting Guide, Audits of Federal Government Contractors, the Company's Inventoried Contract Costs include selling, general and administrative (SG&A) costs, independent research and development (IRAD) costs and bid and proposal (B&P) costs allocated to U.S. Government contracts (revenue arrangements) for which the U.S. Government is the end customer, because they are reimbursable indirect contract costs on

revenue arrangements with the U.S. Government, pursuant to U.S. Government procurement regulations. The Company accounts for SG&A, IRAD and B&P costs allocated to U.S. Government contracts as product costs, instead of period expenses, and charges them to costs of sales when sales are recognized. Therefore, such allocated indirect costs are included in inventoried contract costs prior to the recognition of cost of sales for the related revenue arrangement (contract).

The table below presents a summary of SG&A, IRAD and B&P costs included in inventoried contract costs and the changes to them, including amounts used in the determination of costs and expenses for "Contracts, primarily U.S. Government." The cost data in the table below does not include the SG&A and research and development expenses for the Company's businesses that are primarily not U.S. government contractors, which are separately presented on the statements of operations under costs and expenses for "Commercial, primarily products" and are expensed as incurred.

				Year Ended December 31,
				2004				2003				2002
Amounts included in inventoried contract costs at beginning of period				$	38,024			$	52,253			$	19,970

5.    Goodwill and Other Intangible Assets

Effective January 1, 2002, the Company ceased recording goodwill amortization expense and began testing goodwill for impairment based on estimated fair values at the beginning of the year using a discounted cash flows valuation. Based on the estimated fair values of the Company's reporting units as of January 1, 2002, the goodwill for certain space and broadband commercial communications businesses included in the Specialized Products segment was impaired. In the first quarter of 2002, the Company completed its valuation of the assets and liabilities for these businesses and recorded an impairment charge of $24,370, net of a $6,428 income tax benefit. The impairment charge was recorded as a cumulative effect of a change in accounting principle effective January 1, 2002, in accordance with the adoption provisions of SFAS No. 142.

L-3 Communications

At December 31, 2004, the Company's Senior Credit Facilities were comprised of a $500,000 five-year revolving credit facility maturing on May 15, 2006 and a $250,000 364-day revolving facility. The 364-day revolving credit facility expired on February 22, 2005.

At December 31, 2004, available borrowings under the Company's Senior Credit Facilities were $677,521, after reductions for outstanding letters of credit of $72,479. There were no outstanding borrowings under the Senior Credit Facilities at December 31, 2004.

On March 9, 2005, the Company entered into a new five-year senior revolving credit facility (the New Senior Credit Facility) maturing on March 9, 2010 and allowing for total aggregate borrowings of up to $1,000,000. At March 9, 2005, available borrowings under our new senior credit facility were approximately $906,000, after reductions for outstanding letters of credit of approximately $94,000. At the time the Company entered into this facility, the existing senior credit facility was terminated.

Borrowings under the New Senior Credit Facility bear interest, at L-3 Communications' option, at either: (i) a "base rate" equal to the higher of 0.50% per annum above the latest federal funds rate and the Bank of America "prime rate" (as defined) plus a spread ranging from 0.75% to 0.00% per annum depending on L-3 Communications' Debt Rating at the time of determination or (ii) a "LIBOR rate" (as defined) plus a spread ranging from 1.75% to 0.625% per annum depending on L-3 Communications' Debt Rating at the time of determination. The Debt Rating is based on the ratings as determined by Standard & Poor's Ratings Services, Moody's Investors Service, Inc. and Fitch Ratings of the Company's non-credit-enhanced, senior unsecured long-term debt.

L-3 Communications pays commitment fees calculated on the daily amounts of the available unused commitments under the New Senior Credit Facility at a rate ranging from 0.375% to 0.125% per annum, depending on L-3 Communications' Debt Rating in effect at the time of determination. L-3 Communications pays letter of credit fees calculated at a rate ranging from 1.3125% to 0.46875% per annum for performance and commercial letters of credit and 1.75% to 0.625% for financial letters of credit, in each case depending on L-3 Communications' Debt Rating at the time of determination.

On November 12, 2004, L-3 Communications sold $650,000 of 5 7/8% Senior Subordinated Notes due January 15, 2015 (2004 Notes) with interest payable semi-annually on January 15 and July 15 of each year commencing January 15, 2005. The net cash proceeds from this offering amounted to approximately $639,000 after deducting commissions and other offering expenses and were used to redeem the Company's 8% Senior Subordinated Notes due 2008 and to increase cash and cash equivalents. The 2004 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. On or after January 15, 2010, the 2004 Notes are subject to redemption at any time, at the option of L-3 Communications, in whole or in part, at redemption prices (plus accrued and unpaid interest) starting at 102.938% of the principal amount (plus accrued and unpaid interest) during the 12-month period beginning January 15, 2010 and declining annually to 100% of principal (plus accrued and unpaid interest) on January 15, 2013 and thereafter.

The change was comprised of premiums of $5,334 and $2,751 to write off the remaining balance of unamortized debt issue costs relating to these notes, partially offset by a gain of $3,116 to recognize the remaining balance of the deferred gain on the terminated interest rate swap agreements relating to these notes.

bridge loan facility, (ii) repay the indebtedness outstanding under the Company's Senior Credit Facilities, (iii) repurchase and redeem the 10 3/8% Senior Subordinated Notes due 2007 and (iv) increase cash and cash equivalents. The June 2002 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 June 2002 Notes are subject to redemption at any time, at the option of L-3 Communications, in whole or in part, on or after June 15, 2007 at redemption prices (plus accrued and unpaid interest) starting at 103.813% of the principal amount (plus accrued and unpaid interest) during the 12-month period beginning June 15, 2007 and declining annually to 100% of principal (plus accrued and unpaid interest) on June 15, 2010 and thereafter. Prior to June 15, 2005, L-3 Communications may redeem up to 35% of the June 2002 Notes with the proceeds of certain equity offerings at a redemption price of 107.625% of the principal amount (plus accrued and unpaid interest).

In June of 2002, L-3 Communications commenced a tender offer to purchase any and all of its $225,000 aggregate principal amount of 10 3/8% Senior Subordinated Notes due 2007. The tender offer expired on July 3, 2002. On June 25, 2002, L-3 Communications sent a notice of redemption for all of its 10 3/8% Senior Subordinated Notes due 2007 that remained outstanding after the expiration of the tender offer. Upon sending the notice, the remaining notes became due and payable at the redemption price as of July 25, 2002. During 2002, the Company recorded a pre-tax charge of $16,187, comprised of premiums, fees and other transaction costs of $12,469 and $3,718 to write-off the remaining balance of unamortized debt issue costs relating to these notes.

Depending on interest rate levels, the Company may enter into interest rate swap agreements to convert certain of its fixed interest rate debt obligations to variable interest rates, or terminate any existing interest rate swap agreements. The variable interest rate paid by the Company under the swap agreements is equal to (i) the variable rate basis, plus (ii) the variable rate spread.

On December 22, 2003, L-3 Holdings announced a full redemption of $300,000 of its 5.25% Convertible Senior Subordinated Notes due 2009 (Convertible Notes), which expired on January 9, 2004. At December 31, 2003, holders of approximately $1,630 of the Convertible Notes had exercised their conversion rights and converted such notes into 40,000 shares of L-3 Holdings common stock. On January 9, 2004, holders of $298,183 of the Convertible Notes exercised their conversion rights and converted such notes into 7,317,327 shares of L-3 Holdings common stock. The remaining $187 of Convertible Notes were redeemed on January 12, 2004 for cash. As a result of these conversions and redemptions, L-3's principal amount of long-term debt decreased by $298,370 and shareholders' equity increased by $292,319 in January 2004 compared to December 31, 2003.

Covenants

The New Senior Credit Facilities and Senior Subordinated Notes indentures contain financial and other restrictive covenants that limit, among other things, the ability of the Company to borrow additional funds, incur liens, make investments, merge or consolidate, dispose of assets, or pay dividends. The Company is in compliance with those covenants in all material respects. The Company's New Senior Credit Facility contains covenants that require that (i) the Company's Consolidated Leverage Ratio be less than or equal to 4.0 to 1.0, (ii) the Company's Consolidated Senior Leverage Ratio be less than or equal to 3.0 to 1.0 and (iii) the Company's Consolidated Interest Coverage Ratio be greater than or equal to 3.0 to 1.0. Calculations of the Consolidated Leverage Ratio, Consolidated Senior Leverage Ratio and Consolidated Interest Coverage Ratio are to take into account acquisitions on a pro forma basis as if they had occurred at the beginning of the applicable period.

The Consolidated Leverage Ratio is defined as the ratio of Consolidated Funded Indebtedness, minus the lesser of actual unrestricted domestic cash balances in excess of $25,000 and $250,000, to Consolidated EBITDA. Consolidated Funded Indebtedness is equal to the sum of (1) outstanding indebtedness for borrowed money or for preferred stock accounted for as indebtedness (which is referred to under the New Senior Credit Facility as "disqualified preferred stock"), (2) the deferred purchase price of property or services, (3) capitalized lease obligations and (4) outstanding indebtedness of L-3 Holdings guaranteed by L-3 Communications or its subsidiaries. Consolidated EBITDA is equal to consolidated net income of L-3 Communications (excluding (A) impairment losses incurred on goodwill and other intangible assets or on debt and equity investments, (B) gains or losses incurred on the retirement of debt, (C) extraordinary gains and losses, (D) gains and losses in connection with asset dispositions, and (E) non-cash gains or losses on discontinued operations) for the applicable period, plus consolidated interest expense (including consolidated interest expense of L-3 Holdings for indebtedness guaranteed by L-3 Communications and its subsidiaries), income taxes, depreciation and amortization expense and non-cash stock-based compensation expenses.

The Consolidated Senior Leverage Ratio is defined as the ratio of Consolidated Funded Indebtedness, minus subordinated debt of L-3 Communications and indebtedness of L-3 Holdings that is guaranteed by L-3 Communications on a subordinated basis, to Consolidated EBITDA. The Consolidated Interest Coverage Ratio is defined as the ratio of Consolidated EBITDA to cash interest expense of L-3 Communications and its subsidiaries plus cash interest expense of L-3 Holdings with respect to indebtedness guaranteed by L-3 Communications or any of its subsidiaries.

In addition, the Senior Subordinated Notes indentures contain covenants that restrict the ability of L-3 Communications to incur indebtedness and issue capital stock that matures or is redeemable 91 days or less after the maturity date of such series of notes, and the ability of its restricted subsidiaries to incur indebtedness or issue preferred stock, unless the Company's Fixed Charge Coverage Ratio would have been at least 2.0 to 1.0 on a pro forma basis. The covenants are subject to several exceptions, including an exception for indebtedness under credit facilities up to a specified amount. The Fixed Charge Coverage

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

Ratio is defined as the ratio of Consolidated Cash Flow to Fixed Charges of L-3 Communications and its restricted subsidiaries. Consolidated Cash Flow is equal to the consolidated net income of L-3 Communications, plus extraordinary losses, net losses realized upon an asset sale, income taxes of L-3 Communications and its restricted subsidiaries, consolidated interest expense of L-3 Communications and its restricted subsidiaries (whether or not capitalized), depreciation and amortization expense of L-3 Communications and its restricted subsidiaries, and other non-cash expenses of L-3 Communications and its restricted subsidiaries, minus non-cash items not in the ordinary course of business that increased consolidated net income. Fixed Charges are equal to consolidated interest expense of the Company and its restricted subsidiaries (whether or not capitalized), third-party interest expense guaranteed or secured by the Company and its restricted subsidiaries and preferred stock dividends of the Company and its restricted subsidiaries (other than dividends payable in capital stock of L-3 Communications), grossed up for taxes. Calculations of the Fixed Charge Coverage Ratio are to take into account incurrence, assumption or redemption of indebtedness and acquisitions on a pro forma basis as if they had occurred at the beginning of the applicable period and are to exclude Consolidated Cash Flow from discontinued operations and businesses disposed of and related Fixed Charges under non-continuing obligations.

The New Senior Credit Facility limits the ability of L-3 Communications to pay dividends to and make investments in L-3 Holdings. However, the New Senior Credit Facility permits L-3 Communications to:

•

fund payments of interest on indebtedness of L-3 Holdings and to fund payments of dividends on disqualified preferred stock issued by L-3 Holdings, so long as (1) any such indebtedness or disqualified preferred stock is guaranteed by L-3 Communications and (2) the proceeds received by L-3 Holdings from the issuance of such indebtedness or disqualified preferred stock have been invested by L-3 Holdings in L-3 Communications;

•

fund payments and prepayments of principal of indebtedness of L-3 Holdings and to fund optional and mandatory redemptions of disqualified preferred stock issued by L-3 Holdings, so long as (1) any such indebtedness or disqualified preferred stock is guaranteed by L-3 Communications and (2) the amount of such fundings does not exceed the aggregate amount of investments made by L-3 Holdings in L-3 Communications with the proceeds from any issuance of indebtedness or disqualified preferred stock by L-3 Holdings after March 9, 2005 that is guaranteed by L-3 Communications;

•	pay regularly scheduled dividends on disqualified preferred stock issued by L-3 Communications;

•	redeem disqualified preferred stock issued by L-3 Communications so long as the amount of such redemptions does not exceed the aggregate proceeds received by L-3 Communications from the issuance of disqualified preferred stock;

•

pay other dividends on and make other redemptions of its equity interests (including for the benefit of L-3 Holdings) and make other investments in L-3 Holdings, so long as no default or event of default has occurred and is continuing, up to an aggregate amount of $1,000,000, increased (or decreased) quarterly by an amount equal to 50% of the consolidated net income (or deficit) of L-3 Communications for the quarter, plus (1) 100% of the proceeds from any issuance of capital stock (other than disqualified preferred stock) by L-3 Holdings after March 9, 2005 if those proceeds were invested in L-3 Communications, plus (2) 100% of the proceeds from any issuance of indebtedness or disqualified preferred stock by L-3 Holdings after March 9, 2005 if those proceeds were invested in L-3 Communications and the indebtedness or disqualified preferred stock is not guaranteed by L-3 Communications, plus (3) 100% of the proceeds of any issuances of capital stock (other than disqualified preferred stock) by L-3 Communications after March 9, 2005, minus (4) the aggregate amount of subordinated debt of L-3 Communications

	prepaid after March 9, 2005 (other than in connection with a refinancing) in excess of the aggregate proceeds received from the issuance of subordinated debt by L-3 Communications after March 9, 2005 (other than in connection with a refinancing).

The New Senior Credit Facility contains cross default provisions that are triggered when a payment default occurs or certain other defaults occur that would allow the acceleration of indebtedness, guarantee obligations or certain other agreements of L-3 Communications or its subsidiaries in an aggregate amount of at least $40,000 and those defaults (other than payment defaults and defaults that have resulted in acceleration) have not been cured after 10 days. The Senior Subordinated Notes indentures contain cross acceleration provisions that are triggered when holders of the indebtedness of L-3 Holdings, L-3 Communications or their restricted subsidiaries (or the payment of which is guaranteed by such entities) accelerate at least $10,000 in aggregate principal amount of those obligations.

In addition, the Senior Subordinated Notes indentures contain provisions that limit the ability of L-3 Communications to pay dividends to L-3 Holdings and make investments in L-3 Holdings, subject to exceptions. The indentures permit L-3 Communications to make such restricted payments so long as it would be able to incur at least one dollar of additional indebtedness under the Fixed Charge Coverage Ratio test described above and meets other conditions. Assuming the New Senior Credit Facility had been in effect at December 31, 2004, the restricted payments provisions therein would have been more restrictive as of such date than the other conditions contained in the Senior Subordinated Notes indentures.

Subordination and Guarantees

The borrowings under the New Senior Credit Facility are guaranteed by L-3 Holdings and by substantially all of the material wholly-owned domestic subsidiaries of L-3 Communications on a senior basis. The payment 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 substantially all of L-3 Communications' restricted subsidiaries other than its foreign subsidiaries. The guarantees of the Senior Subordinated Notes rank pari passu with one another and are junior to the guarantees of the New Senior Credit Facility.

In the event that the long-term debt rating of L-3 Communications is reduced below BBB−, or the equivalent, by two of the three rating agencies, Standard & Poor's Ratings Services, Moody's Investors Service, Inc. or Fitch Ratings, L-3 Holdings will be required, within 45 business days, to pledge 100% of the capital stock of L-3 Communications, and L-3 Communications and each subsidiary guarantor will be required to pledge 100% of the capital stock of each of their material wholly-owned domestic subsidiaries and 65% of their material wholly-owned foreign subsidiaries, in favor of the lenders under the New Senior Credit Facility.

9.    Financial Instruments

Fair Value of Financial Instruments.    At December 31, 2004 and 2003, the Company's financial instruments consisted primarily of cash and cash equivalents, billed receivables, notes receivable, equity securities, trade accounts payable, customer advances, Senior Credit Facilities, Senior Subordinated Notes, Convertible Notes, CODES, foreign currency forward contracts, interest rate swap agreements and embedded derivatives related to the issuance of the CODES. The carrying amounts of cash and cash equivalents, billed receivables, trade accounts payable, Senior Credit Facilities, and customer advances are representative of their respective fair values because of the short-term maturities or expected settlement dates of these instruments. The Company's investments in nonreadily marketable securities are stated at estimated fair value, which is generally equal to historical cost, except for those that have

experienced other-than-temporary impairments. The Senior Subordinated Notes are registered, unlisted public debt which are traded in the over-the-counter market and their fair values are based on quoted trading activity. The fair values of the Convertible Notes and CODES are based on quoted prices for the same or similar issues. The fair values of foreign currency forward contracts were estimated based on exchange rates at December 31, 2004 and 2003. The fair values of the embedded derivatives were estimated by discounting expected cash flows using quoted market interest rates. The carrying amounts and estimated fair values of the Company's financial instruments are presented in the table below.

Interest Rate Risk Management.    The Company has entered into interest rate swap agreements on certain of its Senior Subordinated Notes to take advantage of variable interest rates, which are lower than the fixed rates on those notes. These swap agreements exchanged the fixed interest rate for a variable interest rate on a notional amount equal to either a portion or the entire principal amount of the related notes, were denominated in U.S. dollars and have designated maturities which occurred on the interest payment dates of the related Senior Subordinated Notes. Cash payments received from or paid to the counterparties on the interest rate swap agreements are the difference between the amount that the fixed interest rates are greater than or less than the variable contract rates on the designated maturity dates, multiplied by the notional amounts underlying the respective interest rate swap agreements. Cash payments or receipts between the Company and counterparties were recorded as a component of interest expense. The Company manages exposure to counterparty credit risk by entering into the interest rate swap agreements only with major financial institutions that are expected to fully perform under the terms of such agreements. The notional amounts are used to measure the volume of these agreements and do not represent exposure to credit loss. See Note 8 for a table of our interest rate swap agreement that was outstanding as of December 31, 2004.

Foreign Currency Exchange Risk Management.    The Company conducts its operations outside the U.S. in functional currencies other than the U.S. dollar. Additionally, some of the Company's U.S. and foreign operations have contracts with customers which are denominated in currencies other than the functional currencies of those operations. To mitigate the risk associated with certain of these contracts denominated in foreign currency, the Company has entered into foreign currency forward contracts and put options. The Company's activities involving foreign currency forward contracts and put options are designed to hedge the foreign denominated cash paid or received, primarily Canadian dollar, Euro, British Pound and U.S. dollar. The Company manages exposure to counterparty credit risk by entering into foreign currency forward contracts only with major financial institutions that are expected to fully perform under the terms of such contracts. The notional amounts are used to measure the volume of these contracts and do not represent exposure to foreign currency losses.

10.    L-3 Holdings Common Stock

In 2004, L-3 Holdings' Board of Directors declared four quarterly cash dividends each for $0.10 per share, which aggregated $43,418.

On February 10, 2005, L-3 Holdings' Board of Directors increased its regular quarterly cash dividend by 25% to $0.125 per share, payable on March 15, 2005, to shareholders of record on February 22, 2005.

On June 28, 2002, L-3 Holdings sold 14,000,000 shares of its common stock in a public offering for $56.60 per share. Upon closing, L-3 Holdings received net proceeds after deducting discounts, commissions and other offering expenses of $766,780. The net proceeds from this sale, which were contributed to L-3 Communications, and the concurrent sale of senior subordinated notes by L-3 Communications (See Note 8) were used to (i) repay $500,000 borrowed on March 8, 2002, under the Company's senior subordinated bridge loan facility, (ii) repay the indebtedness outstanding under the Company's Senior Credit Facilities, (iii) repurchase and redeem the 10 3/8% Senior Subordinated Notes due 2007 and (iv) increase cash and cash equivalents.

On April 23, 2002, the Company announced that its Board of Directors authorized a two-for-one stock split on all shares of L-3 Holdings common stock. The stock split entitled all shareholders of record at the close of business on May 6, 2002 to receive one additional share of L-3 Holdings common stock for every share held on that date. The additional shares were distributed to shareholders in the form of a stock dividend on May 20, 2002. Upon completion of the stock split, L-3 Holdings had approximately 80 million shares of common stock outstanding. All of L-3 Holdings' historical share and earnings per share (EPS) data have been restated to give effect to the stock split.

On April 23, 2002, the Company's shareholders approved an increase in the number of authorized shares of L-3 Holdings common stock from 100,000,000 to 300,000,000 and an increase in the number of authorized shares of L-3 Holdings preferred stock from 25,000,000 to 50,000,000.

On June 29, 2001, the Company established the L-3 Communications Corporation Employee Stock Purchase Plan (ESPP) and registered 3,000,000 shares of L-3 Holdings common stock, which may be purchased by employees of L-3 Communications Corporation, its U.S. subsidiaries and certain of its foreign subsidiaries through payroll deductions. In general, an eligible employee who participates in the ESPP may purchase L-3 Holdings' common stock at a fifteen percent discount. The Company received $32,931, $26,384 and $17,478 of employee contributions for the ESPP in 2004, 2003 and 2002, respectively. These contributions were recorded as a component of shareholders' equity in the consolidated balance sheet. L-3 Holdings issued 705,178 shares in 2004, 603,599 shares in 2003 and 352,054 shares in 2002 of its common stock to the trustee of the ESPP. In January 2005, the Company issued 322,764 shares of L-3 Holdings' common stock to the trustee of the ESPP relating to contributions received during the period July 1, 2004 to December 31, 2004.

Non-Cash Reductions to Diluted EPS From New Accounting Rule.    On September 30, 2004, the Emerging Issues Task Force (EITF) of the Financial Accounting Standards Board (FASB) reached a consensus on EITF Issue No. 04-8, The Effect of Contingently Convertible Debt on Diluted Earnings Per Share, which addresses when the diluted effect of contingently convertible debt instruments should be included in diluted earnings per share (EPS). EITF 04-8 requires that contingently convertible debt instruments are to be included in the computation of diluted EPS regardless of whether the market price trigger has been met. EITF 04-8 also requires that prior period diluted EPS amounts presented for comparative purposes be restated. The Company adopted the provisions of EITF 04-8 during the 2004 fourth quarter. The impact of applying EITF 04-8 to L-3 Holdings CODES resulted in non-cash reductions to the Company's reported diluted EPS of $0.09 from $2.71 to $2.62 for the year ended December 31, 2003, and $0.03 from $1.93 to $1.90 for the year ended December 31, 2002. See Note 8 above for a discussion of the conversion and redemption of the CODES, which occurred during October 2004.

The following table presents the classification of the Company's net deferred tax assets.

Current deferred tax assets				$	127,066			$	152,785
Long-term deferred tax assets (liabilities)					(7,990	)			100,482
Total net deferred tax assets				$	119,076			$	253,267

At December 31, 2004, the Company's loss carryforwards included $390 of federal net operating loss carryforwards that are subject to limitations and will expire, if unused, between 2011 and 2021, and $58,433 of state net operating losses that will expire, if unused, between 2005 and 2021. The Company also has $18,529 of tax credit carryforwards primarily related to U.S. federal and state research and experimentation credits and state investment tax credits that will expire, if unused, primarily beginning in 2012. The Company believes that it will generate sufficient taxable income, of the appropriate character, to utilize these loss and credit carryforwards before they expire.

The Company is subject to ongoing tax examinations in various jurisdictions, which may result in challenges to tax positions taken and, accordingly, the Company may record adjustments to provisions based on the probable outcomes of such matters. However, the Company believes that the resolution of these matters, after considering amounts accrued, will not have a material effect on its financial position, results of operations or cash flows.

14.    Stock Options

In April 1999, the Company adopted the 1999 Long Term Performance Plan (1999 Plan). Awards under the 1999 Plan may be granted to any employee or to any other individual who provides services to or on behalf of the Company or any of its subsidiaries, subject to the discretion of the Compensation Committee of the Board of Directors. Awards under the 1999 Plan may be in the form of stock options, stock appreciation rights (SARs), restricted stock and other incentive awards, consistent with the 1999 Plan. In April 1997, the Company adopted the 1997 Stock Option Plan (1997 Plan). The 1997 Plan authorizes the Compensation Committee of the Board of Directors to grant stock options to key employees of the Company and its subsidiaries. Awards under both plans are in the form of L-3 Holdings common stock. At December 31, 2004, the number of shares of L-3 Holdings' common stock authorized for grant under the 1999 Plan and 1997 Plan was 23,411,630, of which 6,308,021 shares were available for awards under these plans. The price at which stock options may be granted at shall not be less than the fair market value of L-3 Holdings' common stock on the date of grant. In general, options expire after 10 years and are exercisable ratably over a three year period on the annual anniversary of the date of grant. All of the awards under the 1999 Plan and 1997 Plan granted to employees are non-qualified stock options for U.S. income tax regulations.

The Company awards shares of restricted stock of L-3 Holdings to employees under the 1999 Plan. The Company awarded 80,831 shares on January 1, 2004, 88,245 shares on January 1, 2003, and 54,958 shares on January 1, 2002. The aggregate fair values of the restricted stock awards on their grant dates were $4,151 in 2004, $3,963 in 2003 and $2,473 in 2002. The restricted stock awards granted on January 1, 2004, January 1, 2003 and January 1, 2002 vest three years after the date of grant. Compensation expense charged against pre-tax earnings for these restricted stock awards was $3,325 in 2004, $2,975 in 2003 and $2,134 in 2002. Shareholders' Equity has been reduced by $3,932 at December 31, 2004 for unearned compensation on these restricted stock awards.

15.    Commitments and Contingencies

Operating Leases.    The Company leases certain facilities and equipment under agreements expiring at various dates through 2028. The following table presents future minimum payments under non-cancelable operating leases with initial or remaining terms in excess of one year at December 31, 2004.

				Real Estate				Equipment				Total
2005				$	99,812			$	15,860			$	115,672
2006					65,277				11,311				76,588
2007					57,618				7,872				65,490
2008					49,210				5,459				54,669
2009					44,386				5,114				49,500
Thereafter					165,491				52,131				217,622
Total				$	481,794			$	97,747			$	579,541

Real estate lease commitments have been reduced by minimum sublease rental income of $8,106 due in the future under non-cancelable subleases. Leases covering major items of real estate and equipment contain renewal and/or purchase options. Rent expense, net of sublease income was $79,401 for 2004, $71,779 for 2003 and $65,277 for 2002.

On December 31, 2002, the Company entered into two real estate lease agreements, as lessee, with a third-party lessor, which expire on December 31, 2005 and are accounted for as operating leases. On or before the lease expiration date, the Company can exercise options under the lease agreements to either renew the leases, purchase both properties for $28,000, or sell both properties on behalf of the lessor (the "Sale Option"). If the Company elects the Sale Option, the Company must pay the lessor a residual guarantee amount of $22,673 for both properties, on or before the lease expiration date, and at the time both properties are sold, the Company must pay the lessor a supplemental rent equal to the gross sales proceeds in excess of the residual guarantee amount not to exceed $5,327. For these real estate lease agreements, if the gross sales proceeds are less than the sum of the residual guarantee amount and the supplemental rent, the Company is required to pay a supplemental rent to the extent the reduction in the fair value of the properties are demonstrated by an independent appraisal to have been caused by the Company's failure to properly maintain the properties. The aggregate residual guarantee amounts of $22,673 are included in the future minimum payments under non-cancelable real estate operating lease payments relating to the expiration dates of such leases.

The Company has a contract to provide and operate for the U.S. Air Force (USAF) a full-service training facility, including simulator systems adjacent to a USAF base in Oklahoma. The Company acted as the construction agent on behalf of the third-party owner-lessors for procurement and construction for the simulator systems, which were completed and delivered in August 2002. On December 31, 2002, the Company, as lessee, entered into an operating lease agreement for a term of 15 years for one of the simulator systems with the owner-lessor. At the end of the lease term, the Company may elect to purchase the simulator system at fair market value, which can be no less than $2,552 and no greater than $6,422. If the Company does not elect to purchase the simulator system then on the date of expiration, the Company shall pay to the lessor, as additional rent, $2,552 and return the simulator system to the lessor. The aggregate remaining non-cancelable rental payments under this operating lease are $29,333, including the additional rent of $2,552. On February 27, 2003, the Company, as lessee, entered into an operating lease agreement for a term of 15 years for the remaining simulation systems with the owner-lessor. At the end of the lease term, the Company may elect to purchase the simulator systems at fair market value, which can be no less than $4,146 and no greater than $14,544. If the Company does not elect to purchase

the simulator systems, then on the date of expiration, the Company shall return the simulator systems to the lessor. The aggregate remaining non-cancelable rental payments under this operating lease are $47,662.

U.S. Government Procurement Regulations.     A substantial majority of the Company's revenues are generated from providing products and services under legally binding agreements, or contracts with U.S. Government customers. The U.S. Government 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. The Company is currently cooperating with the U.S. Government on several investigations, none of which the Company anticipates will have a material adverse effect on its consolidated financial position, results of operations or cash flows. 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. In addition, all of the Company's U.S. Government contracts are subject to audit and various pricing and cost controls, and include standard provisions for termination for the convenience of the U.S. Government. U.S. Government contracts and related orders are subject to cancellation if funds for contracts become unavailable or for termination for the convenience of the U.S. Government. Foreign government contracts generally include comparable provisions relating to termination for the convenience of the relevant foreign government.

Environmental Matters.    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, after considering amounts accrued 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 liability can be reasonably estimated.

In connection with the Integrated Systems business acquisition, the Company assumed responsibility for implementing certain corrective actions, required under federal law to remediate the Greenville, Texas site location, and to pay a portion of those remediation costs. The hazardous substances requiring remediation have been substantially characterized, and the remediation system has been partially implemented. The Company has estimated that its share of the remediation cost will not exceed $2,500, and will be incurred over a period of 25 years. The Company believes that it has established adequate reserves for these costs.

Litigation Matters.    Additionally, the Company has been periodically subject to litigation, claims or assessments and various contingent liabilities incidental to its businesses or assumed in connection with certain business aquisitions. With respect to those investigative actions, items of litigation, claims or assessments of which it is aware, management of the Company believes that the likelihood of loss is less than probable that after taking into account certain provisions for these matters, the ultimate resolution of any such investigative actions, items of litigation, claims or assessments will not have a material adverse effect on the consolidated financial position, results of operations or cash flows of the Company. However, as discussed below, the Company is a party to a number of material litigations, for which an adverse determination could have a material adverse effect on the consolidated financial position, results of operations or cash flows of the Company.

L-3 Integrated Systems and its predecessors have been involved in a litigation with Kalitta Air arising from a contract to convert Boeing 747 aircraft from passenger configuration to cargo freighters. The

lawsuit was brought in the northern district of California on January 31, 1997. The aircraft were modified using Supplemental Type Certificates (STCs) issued in 1988 by the Federal Aviation Administration (FAA) to Hayes International, Inc. (Hayes/Pemco) as a subcontractor to GATX/Airlog Company (GATX). Between 1988 and 1990, Hayes/Pemco modified five aircraft as a subcontractor to GATX using the STCs. Between 1990 and 1994, Chrysler Technologies Airborne Systems, Inc. (CTAS), a predecessor to L-3 Integrated Systems, performed as a subcontractor to GATX and modified an additional five aircraft using the STCs. Two of the aircraft modified by CTAS were owned by American International Airways, the predecessor to Kalitta Air. In 1996, the FAA determined that the engineering data provided by Hayes/Pemco supporting the STCs was inadequate and issued an Airworthiness Directive that effectively grounded the ten modified aircraft. The Kalitta Air aircraft have not been in revenue service since that date. The matter was tried in January 2001 against GATX and CTAS with the jury finding fault on the part of GATX but rendering a unanimous defense verdict in favor of CTAS. Certain co-defendants had settled prior to trial. The U.S. Ninth Circuit Court of Appeals reversed and remanded the trial court's summary judgment rulings in favor of CTAS regarding a negligence claim by Kalitta Air, which asserts that CTAS as an expert in aircraft modification should have known that the STCs were deficient, and excluding certain evidence at trial. In preparation for retrial, Kalitta Air submitted to us an expert report on damages that calculated Kalitta Air's damages at either $232,000 or $602,000, depending on different factual assumptions. The Company has retained experts whose reports indicate that, even in the event of an adverse jury finding on the liability issues at trial, Kalitta Air has already recovered amounts from the other parties to the initial suit that the Company believes more than fully compensated Kalitta Air for any damages it incurred. CTAS' insurance carrier has accepted defense of the matter with a reservation of its right to dispute its obligations under the applicable insurance policy in the event of an adverse jury finding. The trial began on January 18, 2005, and ended on March 2, 2005 with a deadlocked jury and mistrial. At trial, Kalitta Air claimed damages of $235,000. Although no date has been set for any further proceedings, a second retrial may be necessary in this matter. The Company believes that it has meritorious defenses and intends to continue to vigorously defend this matter. However, litigation is inherently uncertain and it is possible that an adverse decision could be rendered, which could have a material adverse effect on the consolidated financial position, results of operations or cash flows of 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 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 February 7, 2003, OSI filed an answer and counterclaims alleging, among other things, that the Company defrauded OSI, breached obligations of fiduciary duty to OSI and breached its obligations under the OSI Letter of Intent. OSI seeks damages in excess of $100,000, not including punitive damages. Under the OSI Letter of Intent, the Company proposed selling to OSI the conventional detection business and the ARGUS business that the Company 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. Discovery on the matter is essentially complete. The Company believes that the claims asserted by OSI in its suit are without merit and intends to vigorously defend against the OSI claims.

L-3 Communications Vertex Aerospace LLC (formerly known as Vertex Aerospace LLC and acquired by the Company on December 1, 2003) (L-3 Vertex) is named as a defendant in one remaining wrongful death lawsuit in the United States District Court, Western District of North Carolina arising from the crash of Air Midwest Flight 5481 at Charlotte-Douglas International Airport in Charlotte, North

Carolina on January 8, 2003. The crash resulted in the deaths of nineteen passengers and two crewmembers. Each of the lawsuits alleges contributing factors, including that the accident was caused by the improper maintenance of the aircraft by L-3 Vertex, and seeks to recover compensatory and punitive damages. Twenty claims resulting from this incident have previously settled. The National Transportation Safety Board (NTSB) investigated the cause of the crash and has concluded that the crash was caused by the incorrect rigging of the elevator control system compounded by the airplane's center of gravity, which was substantially aft of the certified limit, with several other contributing factors. L-3 Vertex believes that it has meritorious defenses to the pending lawsuit, and intends to defend the case vigorously. The actions have been tendered to L-3 Vertex's insurance carrier, who has accepted the defense of each action served upon L-3 Vertex to date. L-3 Vertex was also indemnified by Air Midwest for losses L-3 Vertex incurred arising out of its provision of maintenance services to Air Midwest. Based on the availability of insurance and the indemnification from Air Midwest, the Company does not believe it will have a material liability in this matter.

On July 1, 2004, lawsuits were filed on behalf of the estates of 31 Russian children in the state courts of Washington, Arizona, California, Florida, New York and New Jersey against Honeywell, Honeywell TCAS, the Company, ACSS, Thales USA and Thales France. The suits are based on facts arising out of the crash over southern Germany of a Bashkirian Airways Tupelov TU 154M aircraft and a DHL Boeing 757 cargo aircraft. On-board the Tupelov aircraft were 12 crew members and 57 passengers, including 45 children. The Boeing aircraft carried a crew of 3. Both aircrafts were equipped with Honeywell/ACSS Model 2000, Change 7 Traffic Collision and Avoidance Systems. Sensing the other aircraft, the on-board DHL TCAS instructed the DHL pilot to climb, and the Tupelov on-board TCAS instructed the Tupelov pilot to descend. However, the Swiss air traffic controller ordered the Tupelov pilot to climb. The Tupelov pilot disregarded the on-board TCAS and put the Tupelov aircraft into a climb striking the DHL aircraft in midair at approximately 35,000 feet. All crew and passengers of both planes were lost. Investigations by the NTSB after the crash revealed that both TCAS units were performing as designed. The suits allege negligence and strict product liability based upon the design of the units and the training provided to resolve conflicting commands and seek compensatory damages. The Company's insurers have accepted defense of the matter and retained counsel. All parties subsequently agreed to litigate this matter in the Federal Court in New Jersey and to dismiss the actions brought in the state courts. Based on the defenses available to the Company and ACSS and the insurance coverage, the Company does not expect to incur a material liability in this matter.

16.    Pensions and Other Employee Benefits

The Company maintains multiple pension plans, both contributory and non-contributory, covering employees at certain locations. Eligibility for participation in these plans varies and benefits are generally based on the participant's compensation and/or years of service. The Company's funding policy is generally to contribute in accordance with cost accounting standards that affect government contractors, subject to the Internal Revenue Code and regulations thereon. Plan assets are invested primarily in listed stocks, mutual funds, bonds, U.S. Government obligations and U.S. Government agency obligations.

The Company also provides postretirement medical and life insurance benefits for retired employees and dependents at certain locations. Participants are eligible for these benefits when they retire from active service and meet the eligibility requirements for the Company's pension plans. These benefits are funded primarily on a pay-as-you-go basis with the retiree generally paying a portion of the cost through contributions, deductibles and coinsurance provisions.

The following table summarizes the components of net periodic benefit cost for the Company's pension and postretirement benefit plans for the years ended December 31, 2004, 2003 and 2002.

				Pension Plans												Postretirement Benefit Plans

The table below summarizes the weighted average assumptions used to determine the net periodic benefit cost for the years ended December 31, 2004, 2003 and 2002.

				Pension Plans												Postretirement Benefit Plans
				2004				2003				2002				2004				2003				2002
Net periodic benefit cost:
Discount rate					6.25	%			6.75	%			7.25	%			6.25	%			6.75	%			7.25	%
Expected long-term return on plan assets					9.00	%			9.00	%			9.50	%			9.00	%			9.00	%			n.a.
Rate of compensation increase					4.50	%			4.50	%			4.50	%			4.50	%			4.50	%			4.50	%

The expected long-term return on plan asset assumption represents the average rate that the Company expects to earn over the long-term on the assets of the Company's benefit plans, including those from dividends, interest income and capital appreciation. The assumption has been determined based on expectations regarding future rates of return for the plans' investment portfolio, with consideration given to the allocation of investments by asset class and historical rates of return for each individual asset class.

The annual increase in cost of benefits (health care cost trend rate) is assumed to be an average of 9.75% in 2005 and is assumed to gradually decrease to a rate of 5.0% in 2011 and thereafter. Assumed

health care cost trend rates have a significant effect on amounts reported for postretirement medical benefit plans. A one percentage point decrease in the assumed health care cost trend rates would have the effect of decreasing the aggregate service and interest cost by $568 and the postretirement medical obligations by $5,769. A one percentage point increase in the assumed health care cost trend rate would have the effect of increasing the aggregate service and interest cost by $702 and the postretirement medical obligations by $6,344.

Plan Assets.    The Company's Benefit Plan Committee (Committee) has the responsibility to formulate the investment policies and strategies for the plans' assets. These policies and strategies are: (1) invest assets of the plans in a manner consistent with the fiduciary standards of ERISA; (2) preserve the plans' assets; (3) maintain sufficient liquidity to fund benefit payments and pay expenses; (4) evaluate the performance of investment managers; and (5) achieve, on average, a minimum total rate of return equal to the established benchmarks for each asset category.

The Committee retains a professional investment consultant to advise and help ensure that the above policies and strategies are met. The Committee does not involve itself with the day to day operations and selection process of individual securities and investments, and, accordingly, has retained the professional services of investment management organizations to fulfill those tasks. The investment management organizations have investment discretion over the assets placed under their management. The Committee provides each investment manager with specific investment guidelines relevant to its asset class.

The Committee has established the allowable range that plans' assets may be invested in for each major asset category and regularly monitors each to make sure that the actual investment allocation remains within guidelines. The table below presents the range for each major category of the plans' assets at December 31, 2004.

Asset Category				Range
Domestic equity				40%–60%
International equity				5%–15%
Fixed income				25%–35%
Real estate securities				5%–15%
Cash and cash equivalents				0%–20%

The following table presents the Company's pension plan and postretirement benefit plan weighted-average asset allocations at year-end 2004 and 2003, by asset category.

Asset Category				2004				2003
Domestic equity					46	%			44	%
International equity					14				7
Fixed income securities					23				25
Real estate securities					7				7
Other, primarily cash and cash equivalents					10				17
Total					100	%			100	%

Contributions.    For 2005, the Company expects to contribute cash of approximately $70,000 to its pension plans and $13,000 to its postretirement benefit plans.

In connection with the Company's acquisition in 1997 of the ten business units from Lockheed Martin and the formation of the Company, the Company assumed certain defined benefit pension plan liabilities for present and former employees and retirees of certain businesses, which were transferred from Lockheed Martin to the Company. Lockheed Martin also has provided the Pension Benefit Guaranty

Corporation (PBGC) with commitments to assume sponsorship or other forms of financial support under certain circumstances with respect to the Company's pension plans for Communication Systems West and Aviation Recorders (the "Subject Plans"). Upon the occurrence of certain events, Lockheed Martin, at its option, has the right to decide whether to cause the Company to transfer sponsorship of any or all of the Subject Plans to Lockheed Martin, even if the PBGC has not sought to terminate the Subject Plans. If Lockheed Martin did assume sponsorship of these plans, it would be primarily liable for the costs associated with funding the Subject Plans or any costs associated with the termination of the Subject Plans but the Company would be required to reimburse Lockheed Martin for these costs. To date, there has been no impact on pension expense and funding requirements resulting from this arrangement. However, should Lockheed Martin assume sponsorship of the Subject Plans or if these plans were terminated, the impact of any increased pension expenses or funding requirements could be material to the Company. For the year ended December 31, 2004, the Company contributed $492 to the Subject Plans. The Company has performed its obligations under the letter agreement with Lockheed Martin and the Lockheed Martin Commitment and has not received any communications from the PBGC concerning actions which the PBGC contemplates taking in respect of the Subject Plans.

Estimated Future Benefit Payments.    The following table presents expected pension and postretirement benefit payments and expected postretirement subsidies due to the Medicare Act described in Note 2, which reflect expected future service, as appropriate.

Employee Savings Plans.    Under its various employee savings plans, the Company matches the contributions of participating employees up to a designated level. The extent of the match, vesting terms and the form of the matching contributions vary among the plans. Under these plans, the Company's matching contributions in L-3 Holdings' common stock and cash were $61,184 for 2004, $43,262 for 2003 and $36,120 for 2002.
