2.  Basis of Presentation

These unaudited condensed consolidated financial statements for the quarterly period ended March 26, 2010 should be read in conjunction with the audited consolidated financial statements of L-3 Holdings and L-3 Communications included in their Annual Report on Form 10-K for the fiscal year ended December 31, 2009.

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, and its only obligations are: (1) the 3% Convertible Contingent Debt Securities (CODES) due 2035, which were issued by L-3 Holdings on July 29, 2005, (2) its guarantee of borrowings under the revolving credit facility of L-3 Communications and (3) its guarantee of other contractual obligations of L-3 Communications and its subsidiaries. L-3 Holdings’ obligations relating to the CODES have been jointly, severally, fully and unconditionally guaranteed by L-3 Communications and certain of its wholly-owned domestic subsidiaries. Accordingly, such debt has been reflected as debt of L-3 Communications in its consolidated financial statements in accordance with the accounting standards for pushdown accounting. All issuances of and conversions into L-3 Holdings’ equity securities, including grants of stock options, restricted stock, restricted stock units and

NOTES TO UNAUDITED CONDENSED CONSOLIDATED
FINANCIAL STATEMENTS (Continued)

performance units by L-3 Holdings to employees and directors of L-3 Communications and its subsidiaries, 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 23 for additional information regarding the unaudited financial information of L-3 Communications and its subsidiaries.

The unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X of the SEC. Accordingly, they do not include all of the disclosures required by U.S. GAAP for a complete set of annual audited financial statements. In the opinion of management, all adjustments (consisting of normal and recurring adjustments) considered necessary for a fair presentation of the results for the interim periods presented have been included. The results of operations for the interim periods are not necessarily indicative of results for the full year.

Certain reclassifications have been made to conform prior year amounts to the current year presentation.

It is the Company’s established practice to close its books for the quarters ending March, June and September on the Friday nearest to the end of the calendar quarter. The interim unaudited condensed consolidated financial statements included herein have been prepared and are labeled based on that convention. The Company closes its annual books on December 31 regardless of what day it falls on.

The preparation of financial statements in conformity with U.S. GAAP 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 of sales during the reporting period. The most significant of these estimates and assumptions relate to contract revenue, profit and loss recognition, fair values of assets acquired and liabilities assumed in business combinations, market values for inventories reported at lower of cost or market, pension and post-retirement benefit obligations, stock-based employee compensation expense, income taxes, including the valuations of deferred tax assets, litigation reserves and environmental obligations, accrued product warranty costs, and the recoverability, useful lives and valuation of recorded amounts of long-lived assets, identifiable intangible assets and goodwill. Changes in estimates are reflected in the periods during which they become known. Actual amounts will differ from these estimates and could differ materially. For a more complete discussion of these estimates and assumptions, see the Annual Report of L-3 Holdings and L-3 Communications on Form 10-K for the fiscal year ended December 31, 2009.

3.  New Accounting Standards Implemented

In June 2009, the Financial Accounting Standards Board (FASB) issued a revised standard for the accounting for variable interest entities (VIE), which replaces the quantitative-based risks and rewards approach with a qualitative approach and requires certain additional disclosures. The new qualitative approach focuses on determining which entity has the power and control to direct the activities of a VIE and requires an ongoing assessment of that conclusion. The revised accounting standard was effective for the Company beginning on January 1, 2010 and did not have a material impact on the Company’s financial position, results of operations or cash flows.

⁽¹⁾ The net decrease in goodwill from foreign currency translation adjustments is due to the strengthening of the U.S. dollar during the quarter ended March 26, 2010 against the functional currencies of L-3’s foreign subsidiaries in Germany and the United Kingdom, which was partially offset by the weakening of the U.S. dollar against the Canadian dollar.

Under select conditions, including if L-3 Holdings common stock price is more than 120% (currently $120.17) of the then current conversion price (currently $100.14) for a specified period, the conversion feature of the CODES will require L-3 Holdings, upon conversion, to pay the $700 million principal amount in cash, and if the settlement amount exceeds the principal amount, the excess will be settled in cash or stock or a combination thereof, at the Company’s option. At the current conversion price of $100.14, the aggregate consideration to be delivered upon conversion would be determined based on 7.0 million shares of L-3 Holdings’ common stock. See Note 10 to the audited consolidated financial statements for the year ended December 31, 2009, included in the Company’s Annual Report on Form 10-K for additional information regarding the CODES, including conditions for conversion. L-3 Holdings’ closing stock price on May 3, 2010 was $95.34 per share. The effective interest rate on the CODES is 6.33%. Interest expense relates to both the contractual coupon interest and amortization of the discount on the liability components. Interest expense recognized was $10 million for the first quarter periods ended March 26, 2010 and March 27, 2009. The following table provides additional information about the Company’s CODES:

11.  Income Taxes

The U.S. Federal income tax jurisdiction is the Company’s major tax jurisdiction. The statutes of limitation for the Company’s U.S. Federal income tax returns for the years ended December 31, 2006 through 2008 are open as of March 26, 2010. The Internal Revenue Service (IRS) began its audit of the Company’s 2006 and 2007 U.S. Federal income tax returns in April 2009. In addition, the Company has numerous state and foreign income tax return audits currently in process. As a result of filing an IRS tax accounting method change regarding compensation expense during the quarter ended March 26, 2010, the Company decreased both its unrecognized tax benefits and its current deferred tax assets by $48 million. As of March 26, 2010, the Company anticipates that unrecognized tax benefits will decrease by approximately $7 million over the next 12 months.

⁽¹⁾ L-3 Holdings’ CODES had no impact on diluted EPS for the quarter period ended March 26, 2010 or the quarter period ended March 27, 2009, because the average market price of L-3 Holdings common stock during these periods was less than the price at which the CODES would have been convertible into L-3 Holdings common stock. As of March 26, 2010 the conversion price was $100.14.

Excluded from the computations of diluted EPS are shares related to stock options, restricted stock, and restricted stock units underlying employee stock-based compensation of 2.3 million and 2.8 million for the quarter ended March 26, 2010 and the quarter ended March 27, 2009, respectively, because they were anti-dilutive.

(2)	Level 2 is based on pricing inputs other than quoted prices in active markets, which are either directly or indirectly observable. The fair value is determined using a valuation model based on observable market inputs, including quoted foreign currency forward exchange rates and consideration of non-performance risk.
(3)	Level 3 is based on pricing inputs that are not observable and not corroborated by market data. The Company has no Level 3 assets or liabilities.

15.  Financial Instruments

At March 26, 2010 and December 31, 2009, the Company’s financial instruments consisted primarily of cash and cash equivalents, billed receivables, trade accounts payable, Senior Notes, Senior Subordinated Notes, CODES and foreign currency forward contracts. The carrying amounts of cash and cash equivalents, billed receivables and trade accounts payable are representative of their respective fair values because of the short-term maturities or expected settlement dates of these instruments. The fair value of the Senior Notes, Senior Subordinated Notes and CODES are based on quoted prices for these securities. The fair values of foreign currency forward contracts are

16.  Derivative Financial Instruments

Derivative Financial Instruments. The Company’s derivative financial instruments include foreign currency forward contracts, which are entered into for risk management purposes, and an embedded derivative representing the contingent interest payment provision related to the CODES.

Foreign Currency Forward Contracts. The Company’s U.S. and foreign businesses enter into contracts with customers, subcontractors or vendors that are denominated in currencies other than their functional currencies. To protect the functional currency equivalent cash flows associated with certain of these contracts, the Company enters into foreign currency forward contracts. The Company’s activities involving foreign currency forward contracts are designed to hedge the changes in the functional currency equivalent cash flows due to movements in foreign exchange rates compared to the functional currency. The foreign currencies hedged are primarily the Canadian dollar, the Euro, the British pound and the U.S. dollar. The Company manages exposure to counterparty non-performance 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. Foreign currency forward contracts are recorded in the Company’s condensed consolidated balance sheets at fair value and are generally designated and accounted for as cash flow hedges in accordance with the accounting standards for derivative instruments and hedging activities. Gains and losses on designated foreign currency forward contracts that are highly effective in offsetting the corresponding change in the cash flows of the hedged transactions are recorded net of income taxes in accumulated other comprehensive income (loss) (accumulated OCI) and then recognized in income when the underlying hedged transaction affects income. Gains and losses on foreign currency forward contracts that do not meet hedge accounting criteria are recognized in income immediately.

The estimated net amount of existing gains at March 26, 2010 that is expected to be reclassified into income within the next 12 months is $3 million.

17.  Commitments and Contingencies

U.S. and Foreign 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 and foreign government customers. 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 from which civil, criminal or administrative proceedings could result and give rise to fines, penalties, compensatory and

17

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

NOTES TO UNAUDITED CONDENSED CONSOLIDATED
FINANCIAL STATEMENTS (Continued)

treble damages, restitution and/or forfeitures. The Company does not currently anticipate that any of these investigations will have a material adverse effect, individually or in the aggregate, on its consolidated financial position, results of operations or cash flows. However, under U.S. Government 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 or in a loss of export privileges. 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: (1) are subject to audit and various pricing and cost controls, (2) include standard provisions for termination for the convenience of the U.S. Government or for default, and (3) are subject to cancellation if funds for contracts become unavailable. Foreign government contracts generally include comparable provisions relating to terminations for convenience and default, as well as other procurement clauses relevant to the foreign government.

Litigation Matters

The Company has been subject to and is involved in litigation, government investigations, proceedings, claims or assessments and various contingent liabilities incidental to its businesses, including those specified below. Furthermore, in connection with certain business acquisitions, the Company has assumed some or all claims against, and liabilities of, the acquired business, including both asserted and unasserted claims and liabilities. In accordance with the accounting standard for contingencies, the Company records a liability when management believes that it is both probable that a liability has been incurred and the Company can reasonably estimate the amount of the loss. Generally, the loss is recorded at the amount the Company expects to resolve the liability. The estimated amounts of liabilities recorded for pending and threatened litigation is disclosed in Note 8. Amounts recoverable from insurance contracts or third parties are recorded as assets when deemed probable. At March 26, 2010, the Company did not record any amounts for recoveries from insurance contracts or third parties in connection with the amount of liabilities recorded for pending and threatened litigation. Legal defense costs are expensed as incurred. The Company believes it has recorded adequate provisions for its litigation matters. The Company reviews these provisions quarterly and adjusts these provisions to reflect the impact of negotiations, settlements, rulings, advice of legal counsel and other information and events pertaining to a particular matter. While it is reasonably possible that an unfavorable outcome may occur in one or more of the following matters, unless otherwise stated below, the Company believes that it is not probable that a loss has been incurred in any of these matters. An estimate of loss or range of loss is disclosed for a particular litigation matter when such amount or amounts can be reasonably estimated and no loss has been accrued. The Company believes that any damage amounts claimed in the specific matters discussed below are not meaningful indicators of potential liability. Although the Company believes that it has valid defenses with respect to legal matters and investigations pending against it, litigation is inherently unpredictable, including those that are expected to be resolved with jury trials, for which outcomes are difficult to predict. Therefore, it is possible that the financial position, results of operations or cash flows of the Company could be materially adversely affected in any particular period by the unfavorable resolution of one or more of these or other contingencies.

Kalitta Air. On January 31, 1997, a predecessor of Kalitta Air filed a lawsuit in the U.S. District Court for the Northern District of California (the trial court) asserting, among other things, negligence and negligent misrepresentation against Central Texas Airborne Systems, Inc. (CTAS), a predecessor to L-3 Integrated Systems (L-3 IS), in connection with work performed by a predecessor to CTAS to convert two Boeing 747 aircraft from passenger configuration to cargo freighters. The work was performed using Supplemental Type Certificates (STCs) issued in 1988 by the Federal Aviation Administration (FAA). In 1996, following completion of the work, the FAA issued an airworthiness directive with respect to the STCs that effectively grounded the aircraft. On August 11, 2000, the trial court granted CTAS’ motion for summary judgment as to negligence, dismissing that claim. In January 2001, after a ruling by the trial court that excluded certain evidence from trial, a jury rendered a unanimous defense verdict in favor of CTAS on the negligent misrepresentation claim. On December 10, 2002, the U.S. Court of Appeals for the

18

NOTES TO UNAUDITED CONDENSED CONSOLIDATED
FINANCIAL STATEMENTS (Continued)

Ninth Circuit (the Court of Appeals) reversed the trial court’s decisions as to summary judgment and the exclusion of evidence, and remanded the case for a new trial on both the negligence and negligent misrepresentation claims. The retrial ended on March 2, 2005 with a deadlocked jury and mistrial. On July 22, 2005, the trial court granted CTAS’ motion for judgment as a matter of law as to negligence, dismissing that claim, and denied CTAS’ motion for judgment as a matter of law as to negligent misrepresentation. On October 8, 2008, the Court of Appeals reversed the trial court’s dismissal of the negligence claim and affirmed the trial court’s ruling as to the negligent misrepresentation claim. As a result, the case was remanded to the trial court to reconsider the negligence claim and for further proceedings on the negligent misrepresentation claim. The trial court held a new hearing on CTAS’ motion to dismiss the negligence claim on April 30, 2009, after which it determined to take the matter under advisement. The case is currently scheduled to go to a third trial on November 1, 2010. The parties have participated in court-ordered mediations from time to time, and are expected to participate in future court-ordered mediations prior to trial, but to date such mediations have not resulted in a mutually acceptable resolution of this matter. In connection with these mediations, Kalitta Air has claimed it may seek damages at the third trial of between $430 million and $900 million, including between $200 million and $240 million of pre-judgment interest. CTAS’ insurance carrier has accepted defense of this matter and has retained counsel, subject to a reservation of rights by the insurer to dispute its obligations under the applicable insurance policies in the event of a finding against L-3. The Company believes that it has meritorious defenses to the claims asserted and the damages sought and intends to defend itself vigorously.

Korean Lot II Program. On April 4, 2005, Lockheed Martin Corporation (Lockheed) filed a lawsuit in the U.S. District Court for the Northern District of Georgia alleging that L-3 IS is in breach of its license agreement with Lockheed and is infringing on Lockheed’s intellectual property rights as a result of its performance of a subcontract awarded to L-3 IS for the Korean Lot II program. During the trial that began on May 4, 2009, Lockheed sought disgorgement of the monies paid or payable to L-3 IS under the subcontract (which Lockheed claims to be approximately $315 million) or, under an alternative theory of damages, royalties of approximately $20 million. On May 21, 2009, a jury found in favor of Lockheed and awarded $30 million on the misappropriation claim, approximately $7 million on the breach of license agreement claim, plus legal fees and expenses. On August 28, 2009, L-3 IS filed a motion with the court seeking dismissal or a retrial of the case on various grounds. On March 31, 2010, the court set aside the jury verdict and ordered a new trial based on its findings that Lockheed withheld certain documents from L-3 IS that were required to be produced as part of pre-trial discovery. The date for the new trial has not yet been scheduled.

Aircrew Training and Rehearsal Support (ATARS) Investigation. Following a lawsuit filed by Lockheed on April 6, 2006 in the U.S. District Court for the Middle District of Florida against the Company and certain individuals related to the ATARS II Program (which was settled in November 2007), the Company received Grand Jury subpoenas in November 2006 and December 2007 in connection with an investigation being conducted by the United States Attorney for the Middle District of Florida, Orlando Division. The subpoenas request the production of documents related to Lockheed’s allegations or produced in the civil litigation. The Company is cooperating fully with the U.S. Government.

Titan Government Investigation. In October 2002, The Titan Corporation (Titan) received a grand jury subpoena from the Antitrust Division of the DoJ requesting the production of documents relating to information technology services performed for the U.S. Air Force at Hanscom Air Force Base in Massachusetts and Wright-Patterson Air Force Base in Ohio. Titan was informed that other companies who have performed similar services had received subpoenas as well. The Company acquired Titan in July 2005. On September 20, 2006, counsel for the Company was informed by the New York Field Office of the DoJ’s Criminal Antitrust Division that it was considering indictment. Additionally, a former Titan employee received a letter from the DoJ indicating that he was a target of the investigation. In December 2008, the DoJ contacted the Company to arrange additional employee

interviews concerning a teaming agreement relating to the Wright-Patterson Air Force Base procurement. In January 2010, counsel for the Company was again informed by the New York Field Office that it was considering indictment. If the Field Office recommends indictment then, under normal DoJ procedures, Titan (now known as L-3 Services, Inc.) will be afforded an opportunity to make a presentation to the Criminal Antitrust Division in Washington, D.C. before the DoJ acts on the recommendation. It is not known whether an indictment of L-3 Services or any of its current or former employees will occur. If it does occur, it is possible that L-3 Services could be suspended or debarred from conducting business with the U.S. Government. The Company is cooperating fully with the U.S. Government.

CyTerra Government Investigation. Since November 2006, CyTerra has been served with civil and Grand Jury subpoenas by the DoD Office of the Inspector General and the DoJ and has been asked to facilitate employee interviews. The Company is cooperating fully with the U.S. Government. The Company believes that it is entitled to indemnification for any course of defense related to this matter out of, and has made a claim against, a $15 million escrow fund established in connection with the Company’s acquisition of CyTerra in March 2006.

Bashkirian Airways. 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, Thales USA, Thales France, the Company and Aviation Communications & Surveillance Systems (ACSS), which is a joint venture of L-3 and Thales. The suits relate to the crash over southern Germany of Bashkirian Airways Tupelov TU 154M aircraft and a DHL Boeing 757 cargo aircraft. On-board the Tupelov aircraft were 9 crew members and 60 passengers, including 45 children. The Boeing aircraft carried a crew of two. Both aircraft were equipped with Honeywell/ACSS Model 2000, Change 7 Traffic Collision and Avoidance Systems (TCAS). Sensing the other aircraft, the on-board DHL TCAS instructed the DHL pilot to descend, and the Tupelov on-board TCAS instructed the Tupelov pilot to climb. However, the Swiss air traffic controller ordered the Tupelov pilot to descend. The Tupelov pilot disregarded the on-board TCAS and put the Tupelov aircraft into a descent striking the DHL aircraft in midair at approximately 35,000 feet. All crew and passengers of both planes were lost. Investigations by the National Transportation Safety Board 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 approximately $315 million in damages, including $150 million in punitive damages. The Company’s insurers have accepted defense of this matter and have retained counsel. The matters were consolidated in the U.S. District Court for the District of New Jersey, which has dismissed the actions on the basis of forum non conveniens. The plaintiffs re-filed a complaint on April 23, 2007 with the Barcelona Court’s Registry in Spain. On March 9, 2010, the court ruled in favor of the plaintiffs and entered judgment against ACSS in the amount of approximately $6.7 million, all of which represented compensatory damages. The Company believes that the verdict and the damages awarded are inconsistent with the law and evidence presented. Accordingly, on March 17, 2010, ACSS filed a notice with the court of its intent to appeal. The plaintiffs notified the court on the same date that they also intend to appeal.

Gol Airlines. A complaint was filed on November 7, 2006 in the U.S. District Court for the Eastern District of New York against ExcelAire, Joseph Lepore, Jan Paul Paladino, and Honeywell. On October 23, 2007, an amended complaint was filed to include Lockheed, Raytheon, Amazon Technologies and ACSS. The complaints relate to the September 29, 2006 airplane crash over Brazil of a Boeing 737-800 operated by GOL Linhas Aereas Inteligentes, S.A. and an Embraer 600 business jet operated by ExcelAire. The complaints allege that ACSS designed the Traffic Collision and Avoidance System (TCAS) on the ExcelAire jet, and assert claims of negligence, strict products liability and breach of warranty against ACSS based on the design of the TCAS and the instructions provided for its use. The complaints seek unspecified monetary damages, including punitive damages. The Company’s insurers have accepted defense of this matter and have retained counsel. On July 2, 2008, the District Court dismissed the actions on the basis of forum non conveniens on the grounds that Brazil was the location of the accident and is more

convenient for witnesses and document availability. On December 2, 2009, the U.S. Court of Appeals for the Second Circuit upheld this decision. Some of the plaintiffs re-filed their complaints in the Lower Civil Court in the Judicial District of Peixoto de Azevedo in Brazil on July 3, 2009.

19.  Employee Stock-Based Compensation

On February 23, 2010, the Company granted stock-based compensation awards under the 2008 Long Term Performance Plan (2008 LTPP) in the form of stock options, restricted stock units and performance units.

Stock Options. The Company granted 548,165 stock options with an exercise price equal to the fair market value of L-3 Holdings’ common stock on the date of grant. The options expire after 10 years from the date of grant and vest ratably over a three year period on the annual anniversary of the date of grant. The weighted average grant date fair value for the options awarded was $18.40 and was estimated using the Black-Scholes option-pricing model. The weighted average assumptions used in the valuation model for this grant are presented in the table below:

Expected holding period (in years)	4.7
Expected volatility	26.2	%
Expected dividend yield	2.2	%
Risk-free interest rate	2.3	%

Restricted Stock Units. The Company granted 593,373 restricted stock units with a weighted average grant date fair value of $90.18 per share. These units automatically convert into shares of L-3 Holdings’ common stock

upon vesting, and are subject to forfeiture until certain restrictions have lapsed, including a three year cliff vesting period starting on the date of grant.

Performance Units. The Company granted 67,200 performance units, with a weighted average grant date fair value per unit of $105.19. The payout for these units is based on the achievement of pre-determined performance goals established by the compensation committee of the Company’s board of directors for the three-year period ending December 31, 2012. The payout can range from zero to 200% of the original number of units awarded, which are converted into shares of L-3 Holdings’ common stock and/or an amount of cash based on the then existing closing price at the end of the performance period.

On April 27, 2010, the stockholders of L-3 Holdings approved an amendment to the 2008 LTPP. The principal purpose of the amendment is to increase the number of shares authorized for issuance under the 2008 LTPP to approximately 12.2 million shares, except that each share of L-3 Holdings common stock issued under a “full value” award (awards other than stock options or stock appreciation rights) will be counted as 2.6 shares for purposes of this share limit.

22.  Accounting Standards Issued and Not Yet Implemented

In October 2009, the FASB issued a revised accounting standard for revenue arrangements with multiple deliverables. The revision: (1) removes the objective-and-reliable-evidence-of-fair-value criterion from the separation criteria used to determine whether an arrangement involving multiple deliverables contains more than one unit of accounting, (2) provides a hierarchy that entities must use to estimate the selling price, (3) eliminates the use of the residual method for allocation, and (4) expands the ongoing disclosure requirements. The revised accounting standard is effective for the Company beginning on January 1, 2011, with early adoption permitted. The Company is currently assessing the impact the revised accounting standard will have on its consolidated financial statements.

In October 2009, the FASB issued a revised accounting standard for certain revenue arrangements that include software elements. Under the revised standard, tangible products that contain both software and non-software components that work together to deliver a product’s essential functionality will be removed from the scope of pre-existing software revenue recognition standards. In addition, hardware components of a tangible product containing software components will always be excluded from software revenue recognition standards. The revised accounting standard is effective for the Company beginning on January 1, 2011, with early adoption permitted. The Company is currently assessing the impact the revised accounting standard will have on its consolidated financial statements.

We have the following four reportable segments: (1) C³ISR, (2) Government Services, (3) Aircraft Modernization and Maintenance (AM&M), and (4) Electronic Systems. Financial information with respect to each of our reportable segments is included in Note 21 to our unaudited condensed consolidated financial statements contained

in this quarterly report. C³ISR provides products and services for the global ISR market, C³ systems, networked communications systems and secure communications products. We believe that these products and services are critical elements for a substantial number of major command, control and communication, intelligence gathering and space systems. These products and services are used to connect a variety of airborne, space, ground and sea-based communication systems and are used in the transmission, processing, recording, monitoring, and dissemination functions of these communication systems. Government Services provides a full range of engineering, technical, analytical, information technology (IT), advisory, training, logistics and support services to the DoD, DoS, DoJ, and U.S. Government intelligence agencies and allied foreign governments. AM&M provides modernization, upgrades and sustainment, maintenance and logistics support services for military and various government aircraft and other platforms. We sell these services primarily to the DoD, the Canadian Department of National Defense and other allied foreign governments. Electronic Systems provides a broad range of products and services, including components, products, subsystems, systems, and related services to military and commercial customers in several niche markets across several business areas, including power & control systems, electro-optic/infrared (EO/IR), microwave, simulation & training, precision engagement, aviation products, security & detection, propulsion systems, displays, telemetry & advanced technology, undersea warfare, and marine services.

Key Performance Measures

The primary financial performance measures that L-3 uses to manage its businesses and monitor results of operations are sales growth and operating income growth. Management believes that these financial performance measures are the primary growth drivers for L-3’s earnings per common share and net cash from operating activities. L-3’s business strategy is focused on increasing sales from organic growth and select business acquisitions. We define organic sales growth as the increase or decrease in sales for the current period compared to the prior period, excluding sales in the: (1) current period from business and product line acquisitions that are included in L-3’s actual results of operations for less than twelve months, and (2) prior period from business and product line divestitures that are included in L-3’s actual results of operations for the twelve-month period prior to the divestiture date. We expect to supplement our organic sales growth by selectively acquiring businesses that: (1) add important new technologies, services, and products, (2) provide access to select customers, programs, and contracts and (3) provide attractive returns on investments. The two main determinants of our operating income growth are sales growth and improvements in direct and indirect contract costs. We define operating margin as operating income as a percentage of sales.

Sales Growth. Sales growth for the year ended December 31, 2009 was 5%, comprised of organic sales growth of 4%, and sales growth from business acquisitions, net of divestitures, of 1%. For the quarter ended March 26, 2010 (2010 First Quarter), consolidated net sales of $3,624 million declined by 0.3%, comprised of an organic sales decline of 0.8% and sales growth from acquisitions of $16 million or 0.5%, compared to the quarter ended March 27, 2009 (2009 First Quarter). Currently, we expect 2010 sales growth to be in the low single digits.

For the year ended December 31, 2009, our largest contract (revenue arrangement) in terms of annual sales was the Special Operations Forces Support Activity (SOFSA) contract, which generated approximately 3% of our sales. On March 3, 2009, SOFSA announced that L-3 was not selected to perform on the follow-on contract. L-3 subsequently protested and, as a consequence, SOFSA has taken corrective action, which will include the issuance of a revised solicitation. Once a new solicitation is issued, proposals will be requested from all bidders. We were notified by the customer that a new solicitation will be issued in June 2010, with an expected award date of January 2011. While we may not succeed in winning the recompetition for the next SOFSA contract, we continue to perform on the current contract, which has been extended to January 31, 2011.

As is the case with most other U.S. defense contractors, we have benefited from the upward trend in DoD budget authorization and spending outlays over recent years, including supplemental appropriations for military operations in Iraq and Afghanistan. We expect future DoD budgets, including supplemental appropriations, to grow at a significantly slower pace than the past several years, and to possibly flatten or decline. However, we believe that our businesses should be able to continue to generate modest organic sales growth because we anticipate the defense budget and spending priorities will continue to focus on several areas that match L-3’s core competencies, such as

29

communications and ISR, sensors, special operations support, helicopter crew training and maintenance and simulation & training.

We expect to continue to generate modest annual increases in operating margin as we expect to increase sales, grow sales at a rate faster than the increase in our indirect costs, and improve our overall contract performance. However, we may not be able to continue to expand our operating margin on an annual basis. In addition, business acquisitions and new business, including contract renewals and new contracts, could result in decreased operating margins if their margins are lower than L-3’s operating margin on existing business and contracts. Our business objectives include growing earnings per common share and net cash from operating activities. Improving operating margins is one method for achieving these goals, but it is not the only one.

Business Acquisitions and Business and Product Line Dispositions

Our Annual Report on Form 10-K for the fiscal year ended December 31, 2009 summarizes the business acquisitions and business and product line dispositions that we completed during the three years ended December 31, 2009. All of our business acquisitions are included in our consolidated results of operations from their dates of acquisition. We regularly evaluate potential business acquisitions. On April 14, 2010, we acquired all of the outstanding stock of Insight Technology Incorporated, a manufacturer of mission critical night vision and electro-optical equipment, for a preliminary purchase price of $613 million. The purchase price was funded with cash on hand and is subject to adjustment based on the closing date actual net working capital, which has not been finalized. The final purchase price allocation is expected to be completed by the fourth quarter of 2010.

Results of Operations

The following information should be read in conjunction with our unaudited condensed consolidated financial statements contained in this quarterly report. Our results of operations for the periods presented are affected by our business acquisitions. See Note 4 to our audited consolidated financial statements for the year ended December 31, 2009, included in our Annual Report on Form 10-K, for a discussion of our 2009 business acquisitions.

Consolidated Results of Operations

The table below provides selected financial data for L-3 for the 2010 First Quarter compared with the 2009 First Quarter.

Diluted weighted average common shares outstanding		116.9			118.8			(1.9	)

Net Sales: For the 2010 First Quarter, consolidated net sales declined slightly compared to the 2009 First Quarter. Sales growth from the Command, Control, Communications, Intelligence, Surveillance and Reconnaissance (C³ISR) reportable segment was offset by lower sales from the Government Services, Aircraft Modernization and Maintenance (AM&M) and Electronic Systems reportable segments. Consolidated net sales from acquired businesses were $16 million.

30

Sales from services, which include services performed by businesses primarily in our Government Services, AM&M and C³ISR reportable segments, as well as marine services, simulation & training, and maintenance for security and detection systems within our Electronic Systems reportable segment, increased by $36 million to $1,910 million, representing approximately 53% of consolidated net sales for the 2010 First Quarter, compared to $1,874 million, or approximately 52% of consolidated net sales, for the 2009 First Quarter. The increase in service sales was primarily due to organic sales growth in ISR systems, training and law enforcement support services for the U.S. Army and information technology (IT) support services for the U.S. Special Operations Forces (SOF). These increases were partially offset by reduced subcontractor pass-through sales for systems and software engineering and sustainment services, a decrease for Iraq support, including linguist services, and lower volume for contract field services and SOF support activities.

Sales from products, which primarily includes products from our C³ISR and Electronic Systems reportable segments, decreased by $48 million to $1,714 million, representing approximately 47% of consolidated net sales for the 2010 First Quarter, compared to $1,762 million, or approximately 48% of consolidated net sales for the 2009 First Quarter. The decrease in product sales was primarily due to decreases for combat propulsion systems, precision engagement, and naval power and control systems. These decreases were partially offset by organic sales growth in EO/IR and microwave products. See the reportable segment results below for additional discussion of our sales results.

Operating income and operating margin: The 2010 First Quarter operating income increased by 9% compared to the 2009 First Quarter. Operating margin increased to 11.3% for the 2010 First Quarter from 10.3% for the 2009 First Quarter. The operating margin increase was driven by improved contract performance and favorable sales mix for businesses in the C³ISR and Electronic Systems reportable segments. In addition, lower pension expense of $5 million ($3 million after income taxes, or $0.03 per diluted share), increased operating margin by 10 basis points. See the reportable segment results below for additional discussion of our segment operating margin.

Net interest expense and other income: Net interest expense and other income for the 2010 First Quarter decreased by 5% compared to the same period last year primarily due to lower outstanding debt and income from investments accounted for using the equity method.

Effective income tax rate: The effective tax rate for the 2010 First Quarter increased by 80 basis points compared to the same quarter last year due to the expiration of the U.S. Federal research and experimentation tax credit as of December 31, 2009. In addition, the 2010 First Quarter includes a tax provision of $5 million, or $0.04 per diluted share, related to the U.S. Federal Patient Protection and Affordable Care Act, which changed the tax treatment for certain retiree prescription drug benefits.

Diluted earnings per share and net income attributable to L-3: L-3 Holdings’ diluted earnings per share (diluted EPS) increased by $0.21, or 13%, to $1.87 for the 2010 First Quarter from $1.66 for the 2009 First Quarter, and net income attributable to L-3 increased by $22 million, or 11%, to $221 million from $199 million for the same periods.

Diluted weighted average common shares outstanding: Diluted weighted average common shares outstanding for the 2010 First Quarter decreased by 1.9 million shares, or 2%, compared to the 2009 First Quarter. The decrease was primarily due to repurchases of our common stock in connection with our share repurchase program authorized by our Board of Directors, partially offset by additional shares issued in connection with various employee stock-based compensation programs and contributions to employee savings plans made in common stock.

Operating margin		13.4	%		11.0	%		240	bpts

C³ISR net sales for the 2010 First Quarter increased by 11% compared to the 2009 First Quarter primarily due to increased demand and new business from the U.S. Department of Defense (DoD) for airborne ISR and networked communication systems for manned and unmanned platforms and higher sales volumes for force protection products to foreign ministries of defense.

C³ISR operating income for the 2010 First Quarter increased by 35% compared to the 2009 First Quarter. Operating margin increased by 240 basis points. Higher sales volume, favorable sales mix and improved contract performance increased operating margin by 220 basis points. Lower pension expense of $2 million increased operating margin by 20 basis points.

Operating margin		8.2	%		9.0	%		(80	) bpts

Government Services net sales for the 2010 First Quarter decreased by 6% compared to the 2009 First Quarter. The decrease in sales was primarily due to: (1) reduced subcontractor pass-through sales volume of $45 million related to task order renewals for U.S. Army systems and software engineering and sustainment services that migrated to a contract where L-3 is not a prime contractor and (2) $40 million of lower sales related to Iraq support, including linguist and intelligence support services. These decreases were partially offset by $9 million of higher sales primarily for increased training and law enforcement support services for the U.S. Army due to higher volume on new and existing contracts and information technology support services for the U.S. Special Operations Forces (SOF). Net sales from acquired businesses were $12 million, or 1%.

Government Services operating income for the 2010 First Quarter decreased by 15% compared to the 2009 First Quarter. Operating margin decreased by 80 basis points. Lower margins on select contract renewals and higher costs for a security systems contract for the U.S. Department of Homeland Security reduced operating margin by 120 basis points and timing of the receipt of an award fee for linguist services reduced operating margin by 20 basis points. Acquired businesses reduced operating margin by 10 basis points. These decreases were partially offset by a decline in lower margin subcontractor pass-through sales, which increased operating margin by 70 basis points.

Aircraft Modernization and Maintenance (AM&M)

	First Quarter Ended
	March 26,			March 27,
	2010			2009			Decrease
	(dollars in millions)
Net sales	$	652.1		$	663.5		$	(11.4	)
Operating income		59.5			65.8			(6.3	)
Operating margin		9.1	%		9.9	%		(80	) bpts

AM&M net sales for the 2010 First Quarter decreased by 2% compared to the 2009 First Quarter. The decrease in sales was primarily due to: (1) $7 million of lower sales volume for the Joint Cargo Aircraft contract as a result of a delay in an order which is currently anticipated to be received in the second quarter, (2) $23 million of sales volume declines for contract field services and SOF support activities because of reduced tasking, and (3) $7 million of lower sales volume due to a competitive loss of an aircraft maintenance contract with the U.S. Customs and Border Patrol. These decreases were partially offset by $26 million of higher aircraft modernization sales primarily for U.S. Navy maritime patrol aircraft and SOF special mission aircraft.

AM&M operating income for the 2010 First Quarter decreased by 10% compared to the 2009 First Quarter. Operating margin decreased by 80 basis points. Lower sales volume and prices for system field support and a favorable cost adjustment on an international aircraft modernization contract in the 2009 First Quarter that did not recur in the 2010 First Quarter reduced operating margin by 170 basis points. These decreases were partially offset by an increase in operating margin of 90 basis points primarily due to higher aircraft modernization sales to the DoD and improved contract performance.

33

Electronic Systems

	First Quarter Ended
	March 26,			March 27,			(Decrease)/
	2010			2009			Increase

Operating income		167.1			141.3			25.8
Operating margin		13.4	%		11.2	%		220	bpts

Electronic Systems net sales for the 2010 First Quarter decreased by 1% compared to the 2009 First Quarter reflecting sales volume declines of: (1) $21 million for combat propulsion systems due to a reduction in DoD funding for the Bradley fighting vehicle, (2) $19 million for precision engagement due to contracts nearing completion, (3) $6 million for shipboard electronics and power distribution, conditioning and conversion products primarily for the U.S. Navy, (4) $10 million for commercial shipbuilding products, and (5) $27 million primarily for aviation products, security & detection and displays due to timing of deliveries. These decreases were partially offset by volume increases of: (1) $30 million for EO/IR products, primarily to the U.S. Air Force and U.S. Army, (2) $23 million for microwave products, primarily due to increased deliveries of power devices for satellite communication systems, and (3) $11 million for training & simulation, primarily related to a new U.S. Air Force contract awarded in 2009. Additionally, net sales from the Chesapeake Sciences Corporation acquired business were $4 million.

Electronic Systems operating income for the 2010 First Quarter increased by 18% compared to the 2009 First Quarter. Operating margin increased by 220 basis points. The increase was due to improved contract performance and favorable sales mix primarily for EO/IR products, which increased operating margin by 140 basis points, and an increase of 60 basis points primarily for a volume price adjustment on a supply arrangement. In addition, lower pension expense of $3 million increased operating margin by 20 basis points.

Liquidity and Capital Resources

Anticipated Sources and Uses of Cash Flow

Our primary source of liquidity is cash flow generated from operations. As of March 26, 2010, we also had, subject to certain conditions, $968 million of borrowings available under our $1 billion Revolving Credit Facility, after reductions of $32 million for outstanding letters of credit. Our $1 billion Revolving Credit Facility expires on October 23, 2012. We currently believe that our cash from operating activities together with our cash on hand and available borrowings under our Revolving Credit Facility will be adequate for the foreseeable future to meet our anticipated requirements for working capital, capital expenditures, defined benefit plan contributions, commitments, contingencies, research and development expenditures, business acquisitions (depending on the size), contingent purchase price payments on previous business acquisitions, program and other discretionary investments, interest payments, income tax payments, and, to the extent approved by our board of directors, L-3 Holdings’ dividends and share repurchases, and potential debt repurchases. Holders of our $700 million Convertible Contingent Debt Securities (CODES) may require us to repurchase them in whole or in part at a cash repurchase price equal to 100% of the principal amount (plus accrued and unpaid interest, including contingent interest and additional interest, if any) through the exercise of a “put” option on February 1, 2011. In such an event, we intend to either complete a refinancing of all or a portion of the CODES, if we have the ability to do so on terms and conditions acceptable to us, or repurchase any amount of the CODES put to L-3 with cash on hand. The next scheduled maturity of our existing debt is our $400 million 6¹/₈% Senior Subordinated Notes maturing on July 15, 2013.

Our business may not continue to generate cash flow at current levels, and it is possible that currently anticipated improvements may not be achieved. If we are unable to generate sufficient cash flow from operations to service our debt, we may be required to reduce costs and expenses, sell assets, reduce capital expenditures, refinance all or a portion of our existing debt or obtain additional financing and we may not be able to do so on a timely basis, on satisfactory terms, or at all. 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,

34

are subject to general conditions in or affecting the U.S. defense industry and to general economic, political, financial, competitive, legislative and regulatory factors beyond our control.

On April 14, 2010, we acquired all the outstanding stock of Insight Technology Incorporated, a manufacturer of mission critical night vision and electro-optical equipment, for a preliminary purchase price of $613 million. The purchase price was funded with cash on hand and is subject to adjustment based on the closing date actual net working capital, which has not been finalized. The final purchase price allocation is expected to be completed by the fourth quarter of 2010.

Balance Sheet

Billed receivables increased by $150 million to $1,299 million at March 26, 2010 from $1,149 million at December 31, 2009 primarily due to the timing of billings and collections primarily for government services, ISR systems, microwave, security and detection systems and EO/IR products.

Contracts in process increased $78 million to $2,436 million at March 26, 2010, from $2,358 million at December 31, 2009. The increase included a $3 million reclassification from property, plant and equipment to inventoried contract costs and $75 million from:

•  Increases of $50 million in unbilled contract receivables primarily due to sales exceeding billings for aircraft modernization and networked communications; and

•  Increases of $25 million in inventoried contract costs across several business areas, primarily ordnance, displays and networked communications products to support customer demand.

L-3’s receivables days sales outstanding (DSO) was 70 at March 26, 2010, compared with 66 at December 31, 2009 and 73 at March 27, 2009. We calculate our DSO by dividing: (1) our aggregate end of period billed receivables and net unbilled contract receivables, by (2) our trailing 12 month sales adjusted, on a pro forma basis, to include sales from business acquisitions and exclude sales from business divestitures that we completed as of the end of the period, multiplied by the number of calendar days in the trailing 12 month period (364 days at March 26, 2010, 365 days at December 31, 2009 and 364 days at March 27, 2009). Our trailing 12 month pro forma sales were $15,603 million at March 26, 2010, $15,621 million at December 31, 2009 and $15,099 million at March 27, 2009.

The decrease in current deferred income tax assets and other non-current liabilities (non-current income taxes payable) was due to an Internal Revenue Service tax accounting method change regarding compensation expense during the 2010 First Quarter.

Goodwill decreased by $7 million to $8,183 million at March 26, 2010 from $8,190 million at December 31, 2009. The table below presents the changes in goodwill allocated to our reportable segments.

				Government					Electronic			Consolidated
	C3ISR			Services			AM&M		Systems			Total
	(in millions)
Balance at December 31, 2009	$	870		$	2,320		$	1,158	$	3,842		$	8,190
Foreign currency translation adjustments(1)		(4	)		(1	)		7		(9	)		(7	)
Balance at March 26, 2010	$	866		$	2,319		$	1,165	$	3,833		$	8,183

⁽¹⁾ The net decrease in goodwill from foreign currency translation adjustments is due to the strengthening of the U.S. dollar during the quarter ended March 26, 2010 against the functional currencies of L-3’s foreign subsidiaries, primarily in Germany and the United Kingdom, which was partially offset by the weakening of the U.S. dollar against the Canadian dollar.

The increase in accounts payable was primarily due to the timing of when invoices were received for purchases from third-party vendors and subcontractors and when payments were made. The increase in income taxes payable is due primarily to the timing of the 2010 First Quarter income tax payment, which is not due until the second quarter of the calendar year.

35

The increase in pension and postretirement benefit plan liabilities was primarily due to pension expenses exceeding pension cash contributions during the 2010 First Quarter. We expect to contribute cash of approximately $140 million to our pension plans for all of 2010, of which $4 million was contributed during the 2010 First Quarter.

Non-current deferred income tax liabilities increased primarily due to tax amortization of certain goodwill and other identifiable intangible assets.

Statement of Cash Flows

Quarter Ended March 26, 2010 Compared with Quarter Ended March 27, 2009

The table below provides a summary of our cash flows from operating, investing, and financing activities for the periods indicated.

	First Quarter Ended
	March 26,			March 27,
	2010			2009
	(in millions)
Net cash from operating activities	$	271		$	152
Net cash used in investing activities		(35	)		(122	)
Net cash used in financing activities		(104	)		(256	)

Operating Activities

We generated $271 million of cash from operating activities during the 2010 First Quarter, an increase of $119 million compared with $152 million generated during the 2009 First Quarter. The increase was due to: (1) an increase in net income of $21 million, (2) higher non-cash expenses of $15 million primarily due to higher deferred income taxes, and (3) $83 million of less cash used for changes in operating assets and liabilities, primarily due to working capital improvements, including lower payments for employee salaries and wages due to the timing of pay dates and lower income tax payments. The net cash used for changes in operating assets and liabilities is further discussed above under “Liquidity and Capital Resources — Balance Sheet” beginning on page 35.

Investing Activities

During the 2010 First Quarter, we used $35 million of cash in the aggregate primarily to: (1) pay $26 million for capital expenditures and (2) invest $9 million in an unconsolidated subsidiary accounted for using the equity method.

Financing Activities

Debt

At March 26, 2010, total outstanding debt was $4,118 million, of which $997 million was senior debt and $3,121 million was subordinated debt, compared to $4,112 million at December 31, 2009, of which $996 million was senior debt and $3,116 million was subordinated debt. At March 26, 2010, subject to certain conditions, borrowings available under our Revolving Credit Facility were $968 million, after reduction for outstanding letters of credit of $32 million. There were no borrowings outstanding under our Revolving Credit Facility at March 26, 2010. Our Revolving Credit Facility expires on October 23, 2012. Our outstanding debt has scheduled maturities between July 15, 2013 and August 1, 2035; however, holders of our CODES may require us to repurchase them in whole or in part at a cash price equal to 100% of the principal amount (plus accrued and unpaid interest, including contingent interest and additional interest, if any) through the exercise of a “put” option on February 1, 2011. As a result, the CODES have been classified as a current liability at March 26, 2010. See Note 9 to our unaudited condensed consolidated financial statements contained in this quarterly report for the components of our current and long-term debt at March 26, 2010.

36

Credit Ratings. Our credit ratings as of April 2010 are as follows:

Rating Agency	Senior Debt	Subordinated Debt
Standard & Poor’s	BBB-	BB+
Fitch Ratings	BBB-	BB+
Moody’s Investors Service	Baa2	Ba2

Agency credit ratings are not a recommendation to buy, sell or hold any security, and they may be revised or withdrawn at any time by the rating agency. Each agency’s rating should be evaluated independently of any other agency’s rating. The system and the number of rating categories can vary widely from rating agency to rating agency. Customers usually focus on claims-paying ratings, while creditors focus on debt ratings. Investors use both to evaluate a company’s overall financial strength. The ratings issued on L-3 Communications or its subsidiaries by any of these agencies are announced publicly and are available from the agencies. Our ability to access the capital markets could be impacted by a downgrade in one or more of our debt ratings. If this were to occur, we could incur higher borrowing costs.

Debt Covenants and Other Provisions. The Revolving Credit Facility, Senior Notes and senior subordinated notes contain financial and/or other restrictive covenants. See Note 10 to our audited consolidated financial statements for the year ended December 31, 2009, included in our Annual Report on Form 10-K, for a description of our debt and related financial covenants, including dividend payment and share repurchase restrictions and cross default provisions. As of March 26, 2010, we were in compliance with our financial and other restrictive covenants.

Under select conditions, including if L-3 Holdings’ common stock price is more than 120% (currently $120.17 of the then current conversion price (currently $100.14) for a specified period, the conversion feature of the CODES will require L-3 Holdings, upon conversion, to pay the $700 million principal amount in cash, and if the settlement amount exceeds the principal amount, the excess will be settled in cash or stock or a combination thereof, at our option. See Note 10 to our audited consolidated financial statements for the year ended December 31, 2009, included in our Annual Report on Form 10-K, for additional information regarding the CODES, including conditions for conversion. L-3 Holdings’ closing stock price on May 3, 2010 was $95.34 per share.

Guarantees. The borrowings under the Revolving Credit Facility are fully and unconditionally guaranteed by L-3 Holdings and by substantially all of the material wholly-owned domestic subsidiaries of L-3 Communications on an unsecured senior basis. The payment of principal and premium, if any, and interest on the Senior Notes are fully and unconditionally guaranteed, on an unsecured senior basis, jointly and severally, by L-3 Communications’ material wholly-owned domestic subsidiaries that guarantee any of our other indebtedness. The payment of principal and premium, if any, and interest on the senior subordinated notes are fully and unconditionally guaranteed, on an unsecured senior subordinated basis, jointly and severally, by L-3 Communications’ wholly-owned domestic subsidiaries that guarantee any of our other indebtedness. The payment of principal and premium, if any, and interest on the CODES are fully and unconditionally guaranteed, on an unsecured senior subordinated basis, jointly and severally, by L-3 Communications and its wholly-owned domestic subsidiaries that guarantee any of our other liabilities.

Subordination. The guarantees of the Revolving Credit Facility and the Senior Notes rank senior to the guarantees of the senior subordinated notes and the CODES and rank pari passu with each other. The guarantees of the senior subordinated notes and CODES rank pari passu with each other and are junior to the guarantees of the Revolving Credit Facility and Senior Notes.

Legal Proceedings and Contingencies

For a discussion of accounting standards issued and not yet implemented, see Note 22 to our unaudited condensed consolidated financial statements contained in this quarterly report.

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 total sales growth, sales growth from business acquisitions, organic sales growth, consolidated operating margins, total segment operating margins, interest expense earnings, cash flow, research and development costs, working capital, capital expenditures and other projections, they are subject to several risks and uncertainties, and therefore, it is possible that these statements may not be achieved. Such statements will also be influenced by factors which include, among other things:

•  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;

38

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

•  our ability to retain our existing business and related contracts (revenue arrangements);

•  our ability to successfully compete for and win new business and related contracts (revenue arrangements) and to win re-competitions of our existing contracts;

•  our ability to identify and acquire additional businesses in the future with terms, including the purchase price, that are attractive to L-3 and to integrate acquired business operations;

•  our ability to maintain and improve our consolidated operating margin and total segment operating margin in future periods;

•  our ability to obtain future government contracts (revenue arrangements) on a timely basis;

•  the availability of government funding or cost-cutting initiatives 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, as well as our ability to retain and hire employees with U.S. Government security clearances that are a prerequisite to compete for and to perform work on classified contracts for the U.S. Government;

•  actual future interest rates, volatility and other assumptions used in the determination of pension, benefits and equity-based compensation, as well as the market performance of benefit plan assets;

•  our collective bargaining agreements, our ability to successfully negotiate contracts with labor unions and our ability to favorably resolve labor disputes should they arise;

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

•  global economic uncertainty;

•  the DoD’s contractor support services in-sourcing initiative;

•  events beyond our control such as acts of terrorism;

•  our ability to perform contracts (revenue arrangements) on schedule;

•  our international operations, including sales to foreign customers;

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

•  the rapid change of technology and high level of competition in the defense industry and the commercial industries in which our businesses participate;

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

•  the outcome of current or future litigation matters, including those that are expected to be resolved by jury trials, which are inherently risky and for which outcomes are difficult to predict;

•  results of audits by U.S. Government agencies, including the Defense Contract Audit Agency, of our sell prices, costs and performance on contracts (revenue arrangements), and our accounting and general business practices;

39

•  anticipated cost savings from business acquisitions not fully realized or realized within the expected time frame;

•  outcome of matters relating to the Foreign Corrupt Practices Act (FCPA);

•  ultimate resolution of contingent matters, claims and investigations relating to acquired businesses, and the impact on the final purchase price allocations;

•  significant increases in competitive pressure among companies in our industry; 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 other factors, some of which are discussed above.

In addition, for a discussion of other risks and uncertainties that could impair our results of operations or financial condition, see “Part I — Item 1A — Risk Factors” and Note 19 to our audited consolidated financial statements, in each case included in our Annual Report on Form 10-K for the year ended December 31, 2009.

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 in circumstances or changes in expectations or the occurrence of anticipated events.

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 related to L-3 Holdings and L-3 Communications is recorded, processed, summarized and reported within the time periods specified in the U.S. Securities and Exchange Commission’s (SEC) rules and forms, and that such information is accumulated and communicated to our management, including our Chairman, President and Chief Executive Officer, and our Senior Vice President and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures. Any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. Our management, with the participation of our Chairman, President and Chief Executive Officer, and our Senior Vice President and Chief Financial Officer, has evaluated the effectiveness of the design and

40

operation of our disclosure controls and procedures as of March 26, 2010. Based upon that evaluation and subject to the foregoing, our Chairman, President and Chief Executive Officer, and our Senior Vice President and Chief Financial Officer concluded that, as of March 26, 2010, the design and operation of our disclosure controls and procedures were effective to accomplish their objectives at the reasonable assurance level.

There were no changes in our internal control over financial reporting that occurred during the quarter ended March 26, 2010 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

     Any one or more Awards may be granted to any Employee, or any non-Employee who provides services to or on behalf of the Corporation or any of its Subsidiaries, who is designated by the Committee to receive an Award.

SECTION 4. Awards.

     (a) Type of Awards. The Committee may from time to time grant any of the following types of Awards, either singly, in tandem or in combination with other Awards:

     (1) Nonqualified Stock Options. A Nonqualified Stock Option is an Award in the form of an option to purchase Stock that is not intended to comply with the requirements of Code Section 422. The exercise price of each Nonqualified Stock Option granted under this Plan shall not be less than the Fair Market Value of the Stock on the date that the Option is granted.

3

     (2) Incentive Stock Options. An Incentive Stock Option is an Award in the form of an option to purchase Stock that is intended to comply with the requirements of Code Section 422 or any successor section thereof. The exercise price of each Incentive Stock Option granted under this Plan shall not be less than the Fair Market Value of the Stock on the date the Option is granted. If a Participant on the date an Incentive Stock Option is granted owns, directly or indirectly within the meaning of Code Section 424(d), stock possessing more than ten percent (10%) of the total combined voting power of all classes of stock of the Corporation, the exercise price per share of the Incentive Stock Option shall not be less than one hundred and ten percent (110%) of the Fair Market Value per share of the Stock at the time of grant, and such Incentive Stock Option shall not be exercisable after the expiration of five (5) years from the date such Incentive Stock Option is granted. To the extent that the aggregate Fair Market Value of Stock with respect to which one or more incentive stock options first become exercisable by a Participant in any calendar year exceeds $100,000, taking into account both Stock subject to Incentive Stock Options under this Plan and stock subject to incentive stock options under all other plans of the Corporation or of other entities referenced in Code Section 422(d)(1), the options shall be treated as Nonqualified Stock Options. For this purpose, the Fair Market Value of the Stock subject to options shall be determined as of the date the Options were granted.

     (3) Stock Appreciation Rights. A Stock Appreciation Right is an Award in the form of a right to receive, upon surrender of the right, but without other payment, an amount based on the appreciation in the value of the Stock or the Option over a base price established in the Award, payable in cash, Stock or such other form or combination of forms of payout, at times and upon conditions (which may include a Change in Control), as may be approved by the Committee. The minimum base price of a Stock Appreciation Right granted under this Plan shall not be less than the Fair Market Value of the underlying Stock on the date the Stock Appreciation Right is granted.

     (4) Restricted Stock. Restricted Stock is an Award of issued shares of Stock of the Corporation (other than Minimum Ownership Stock) that are subject to restrictions on transfer and/or such other restrictions on incidents of ownership as the Committee may determine.

     (5) Other Share-Based Awards. The Committee may from time to time grant Awards under this Plan that provide the Participants with Stock or the right to purchase Stock, or provide other incentive Awards (including, but not limited to, Minimum Ownership Stock, phantom stock or units, performance stock or units, bonus stock, dividend equivalent units, or similar securities or rights) that have a value derived from the value of, or an

4

exercise or conversion privilege at a price related to, or that are otherwise payable in shares of Stock. The Awards shall be in a form determined by the Committee, provided that the Awards shall not be inconsistent with the other express terms of this Plan applicable to such Awards.

     (b) Special Performance-Based Awards. Without limiting the generality of the foregoing, any of the type of Awards listed in Section 4(a) may be granted as awards that satisfy the requirements for “performance-based compensation” within the meaning of Code Section 162(m) (“Performance-Based Awards”), the grant, vesting, exercisability or payment of which may depend on the degree of achievement of the Performance Goals relative to preestablished targeted levels for the Corporation or any of its Subsidiaries, divisions or other business units. Performance-Based Awards shall be subject to the requirements of clauses (1) through (7) below, except that notwithstanding anything contained in this Section 4(b) to the contrary, any Option or Stock Appreciation Right intended to qualify as a Performance-Based Award shall not be subject to the requirements of clauses (2), (4), (5) and (6) below (with such Awards hereinafter referred to as a “Qualifying Option” or a “Qualifying Stock Appreciation Right”, respectively). An Award that is intended to satisfy the requirements of this Section 4(b) shall be designated as a Performance-Based Award at the time of grant.

     (1) Eligible Class. The eligible class of persons for Awards under this Section 4(b) shall be all Employees.

     (2) Performance Goals. The performance goals for any Awards under this Section 4(b) (other than Qualifying Options and Qualifying Stock Appreciation Rights) shall be, on an absolute or relative basis, one or more of the Performance Goals. The specific performance target(s) with respect to Performance Goal(s) must be established by the Committee in advance of the deadlines applicable under Code Section 162(m) and while the performance relating to the Performance Goal(s) remains substantially uncertain.

     (3) Individual Limits. The maximum number of shares of Stock or Share Units that are issuable under Options, Stock Appreciation Rights, Restricted Stock or other Awards (described under Section 4(a)(5)) that are granted as Performance-Based Awards to any Participant shall not exceed five percent of the total shares outstanding of the Corporation during the life of the Plan, either individually or in the aggregate, subject to adjustment as provided in Section 7. The maximum number of shares of Stock and Share Units issuable or payable pursuant to all Performance-Based Awards (including Qualifying Options and Qualifying Stock Appreciation Rights) granted during a calendar year to any Employee shall be 500,000, subject to adjustment as provided in Section 7. Awards that are cancelled during the year shall be counted against these limits to the extent required by Code Section 162(m).

5

     (4) Committee Certification. Before any Performance-Based Award under this Section 4(b) (other than Qualifying Options and Qualifying Stock Appreciation Rights) is paid, the Committee must certify in writing (by resolution or otherwise) that the applicable Performance Goal(s) and any other material terms of the Performance-Based Award were satisfied; provided, however, that a Performance-Based Award may be paid without regard to the satisfaction of the applicable Performance Goal in the event of the Participant’s death or permanent disability or in the event of a Change in Control as provided in Section 7(b).

     (5) Terms and Conditions of Awards. Committee Discretion to Reduce Performance Awards. The Committee shall have discretion to determine the conditions, restrictions or other limitations, in accordance with the terms of this Plan and Code Section 162(m), on the payment of individual Performance-Based Awards under this Section 4(b). To the extent set forth in an Award Agreement, the Committee may reserve the right to reduce the amount payable in accordance with any standards or on any other basis (including the Committee’s discretion), as the Committee may impose.

     (6) Adjustments for Material Changes. To the extent set forth in an Award Agreement, in the event of (i) a change in corporate capitalization, a corporate transaction or a complete or partial corporate liquidation, or (ii) any extraordinary gain or loss or other event that is treated for accounting purposes as an extraordinary item under generally accepted accounting principles, or (iii) any material change in accounting policies or practices affecting the Corporation and/or the Performance Goals or targets, the Committee shall make adjustments to the Performance Goals and/or targets, applied as of the date of the event, and based solely on objective criteria, so as to neutralize, in the Committee’s judgment, the effect of the event on the applicable Performance-Based Award.

     (7) Interpretation. Except as specifically provided in this Section 4(b), the provisions of this Section 4(b) shall be interpreted and administered by the Committee in a manner consistent with the requirements for exemption of Performance-Based Awards granted to Executive Officers as “performance-based compensation” under Code Section 162(m) and regulations and other interpretations issued by the Internal Revenue Service thereunder.

SECTION 5. Shares of Stock and Share Units Available Under Plan.

     (a) Aggregate Limits on Shares and Share Units. (i) Subject to Section 5(b), the maximum number of shares of Stock that may be issued pursuant to all Awards under the Plan is 12,220,667, (ii) the maximum number of such shares of Stock that may be issued pursuant to all Awards of Incentive Stock

6

Options is 3,000,000, and (iii) the maximum number of shares of Stock and Share Units that may be issuable or payable pursuant to all Awards granted during a calendar year to any Participant shall be 500,000, in each case subject to adjustment as provided in this Section 5 or Section 7.

     (b) Share Usage for Full Value Awards. Solely for purposes of calculating the number of shares of Stock available for issuance pursuant to Section 5(a)(i), each share of Stock that may be issued pursuant to Awards granted on or after March 1, 2010 (other than Awards of Options and Stock Appreciation Rights) shall be counted as 2.6 shares.

     (c) Reissue of Shares and Share Units. Any unexercised, unconverted or undistributed portion of any expired, cancelled, terminated or forfeited Award, or any alternative form of consideration under an Award that is not paid in connection with the settlement of an Award or any portion of an Award, shall again be available for Awards under Sections 5(a) and (b), as applicable, whether or not the Participant has received benefits of ownership (such as dividends or dividend equivalents or voting rights) during the period in which the Participant’s ownership was restricted or otherwise not vested. To the extent an Award is settled in cash in lieu of issuing shares of Stock subject thereto, such shares shall be deemed to constitute Share Units (and not shares of Stock issued pursuant to an Award) for purposes of the limits set forth in Sections 5(a) and (b). For the avoidance of doubt, the following shares of Stock shall not become available for reissuance under the Plan: (1) shares tendered by Participants as full or partial payment to the Corporation upon exercise of Options or other Awards granted under the Plan; (2) shares of Stock reserved for issuance upon the grant of Stock Appreciation Rights, to the extent the number of reserved shares exceeds the number of shares actually issued upon exercise of the Stock Appreciation Rights; and (3) shares withheld by, or otherwise remitted to, the Corporation to satisfy a Participant’s tax withholding obligations upon the lapse of restrictions on Restricted Stock or the exercise of Options or Stock Appreciation Rights or upon any other payment or issuance of shares under any other Award granted under the Plan.

     (d) Interpretive Issues. Additional rules for determining the number of shares of Stock or Share Units authorized under this Plan may be adopted by the Committee, as it deems necessary or appropriate.

     (e) Treasury Shares; No Fractional Shares. The Stock which may be issued (which term includes Stock reissued or otherwise delivered) pursuant to an Award under this Plan may be treasury or authorized but unissued Stock or Stock acquired, subsequently or in anticipation of a transaction under this Plan, in the open market or in privately negotiated transactions to satisfy the requirements of this Plan. No fractional shares shall be issued but fractional interests may be accumulated.

7

     (f) Consideration. The Stock issued under this Plan may be issued (subject to Section 10(d)) for any lawful form of consideration, the value of which equals the par value of the Stock or such greater or lesser value as the Committee, consistent with Sections 10(d) and 4(a)(1), (2) and (3), may require.

     (g) Purchase or Exercise Price; Withholding. The exercise or purchase price (if any) of the Stock issuable pursuant to any Award and any withholding obligation under applicable tax laws shall be paid at or prior to the time of the delivery of such Stock in cash or, subject to the Committee’s express authorization and the restrictions, conditions and procedures as the Committee may impose, any one or combination of (i) cash, (ii) the delivery of shares of Stock, or (iii) a reduction in the amount of Stock or other amounts otherwise issuable or payable pursuant to such Award. In the case of a payment by the means described in clause (ii) or (iii) above, the Stock to be so delivered or offset shall be determined by reference to the Fair Market Value of the Stock on the date as of which the payment or offset is made.

     (h) Cashless Exercise. The Committee may also permit the exercise of the Award and payment of any applicable withholding tax in respect of an Award by delivery of written notice, subject to the Corporation’s receipt of a third party payment in full in cash (or in such other form as permitted under Section 5(g)) for the exercise price and the applicable withholding at or prior to the time of issuance of Stock, in the manner and subject to the procedures as may be established by the Committee.

SECTION 6. Award Agreements.

     Each Award under this Plan shall be evidenced by an Award Agreement in a form approved by the Committee setting forth the number of shares of Stock or Share Units, as applicable, subject to the Award, and the price (if any) and term of the Award and, in the case of Performance-Based Awards, the applicable Performance Goals, if any. The Award Agreement shall also set forth (or incorporate by reference) other material terms and conditions applicable to the Award as determined by the Committee consistent with the limitations of this Plan.

     (a) Incorporated Provisions. Award Agreements shall be subject to the terms of this Plan and shall be deemed to include the following terms:

     (1) Transferability: An Award shall not be assignable nor transferable, except by will or by the laws of descent and distribution, and during the lifetime of a Participant the Award shall be exercised only by such Participant or by his or her guardian or legal representative, except that Awards, other than Incentive Stock Options, may be transferred to and thereafter exercised by a family member or family members of a Participant, or transferred to an irrevocable trust or trusts (or other similar estate

8

planning entity or entities) established for the benefit of a Participant and/or one or more of the Participant’s family members, during the Participant’s lifetime. The designation of a Beneficiary hereunder shall not constitute a transfer prohibited by the foregoing provisions.

     (2) Rights as Stockholder: A Participant shall have no rights as a holder of Stock with respect to any unissued securities covered by an Award until the date the Participant becomes the holder of record of these securities. Except as provided in Section 7, no adjustment or other provision shall be made for dividends or other stockholder rights, except to the extent that the Award Agreement provides for dividend equivalents or similar economic benefits.

     (3) Withholding: The Participant shall be responsible for payment of any taxes or similar charges required by law to be withheld from an Award or an amount paid in satisfaction of an Award and these obligations shall be paid by the Participant on or prior to the payment of the Award. In the case of an Award payable in cash, the withholding obligation shall be satisfied by withholding the applicable amount and paying the net amount in cash to the Participant. In the case of an Award paid in shares of Stock, a Participant shall satisfy the withholding obligation as provided in Section 5(g) or Section 5(h).

     (4) Option Holding Period: Subject to the authority of the Committee under Section 7, and except as otherwise provided by the Committee or as allowed under Rule 16b-3 of the Exchange Act, a minimum six-month period shall elapse between the date of initial grant of any Option and the sale of the underlying shares of Stock, and the Corporation may impose legend and other restrictions on the Stock issued on exercise of the Options to enforce this requirement; provided, however, that such limitation shall not apply to the extent provided by the Committee on account of the Participant’s death, permanent disability or retirement or in the event of a Change in Control as provided in Section 7(b).

     (5) Maximum Term of Awards. No Award that contemplates exercise or conversion may be exercised or converted to any extent, and no other Award that defers vesting, shall remain outstanding and unexercised, unconverted or unvested more than ten years after the date the Award was initially granted.

     (b) Other Provisions. Award Agreements may include other terms and conditions as the Committee shall approve, including but not limited to the following:

9

     (1) Termination of Employment: A provision describing the treatment of an Award in the event of the retirement, disability, death or other termination of a Participant’s employment with or services to the Company, including any provisions relating to the vesting, exercisability, forfeiture or cancellation of the Award in these circumstances, subject, in the case of Performance-Based Awards, to the requirements for “performance-based compensation” under Code Section 162(m).

     (2) Vesting; Effect of Termination; Change in Control: Any other terms consistent with the terms of this Plan as are necessary and appropriate to effect the Award to the Participant, including but not limited to the vesting provisions, any requirements for continued employment, any other restrictions or conditions (including performance requirements) of the Award, and the method by which (consistent with Section 7) the restrictions or conditions lapse, and the effect on the Award of a Change in Control. Unless otherwise provided by the Committee in the applicable Award Agreement, (1) the minimum vesting period for Awards of Restricted Stock shall be three years from the date of grant (or one year in the case of Restricted Stock Awards that are Performance-Based Awards) and (2) the vesting period of an Award of Restricted Stock may not be accelerated to a date that is within such minimum vesting period except in the event of the Participant’s death, permanent disability or retirement or in the event of a Change in Control.

     (3) Replacement and Substitution: Any provisions permitting or requiring the surrender of outstanding Awards or securities held by the Participant in whole or in part in order to exercise or realize rights under or as a condition precedent to other Awards, or in exchange for the grant of new or amended Awards under similar or different terms; provided, that except in connection with an adjustment contemplated by Section 7, no such provisions of an Award Agreement shall permit a “Repricing” as defined in Section 8(d).

     (4) Dividends: Any provisions providing for the payment of dividend equivalents on unissued shares of Stock or unpaid Share Units underlying an Award, on either a current or deferred or contingent basis, and either in cash or in additional shares of Stock; provided that dividend equivalents may not be paid with respect to Awards of Options or Stock Appreciation Rights.

     (c) Contract Rights, Forms and Signatures. Any obligation of the Corporation to any Participant with respect to an Award shall be based solely upon contractual obligations created by this Plan and an Award Agreement. No Award shall be enforceable until the Award Agreement has been signed on behalf of the Corporation by an Executive Officer (other than the recipient) or his or her delegate. By accepting receipt of the Award Agreement, a Participant shall be deemed to have accepted and consented to the terms of this Plan and any action taken in good faith

10

under this Plan by and within the discretion of the Committee, the Board of Directors or their delegates. Unless the Award Agreement otherwise expressly provides, there shall be no third party beneficiaries of the obligations of the Corporation to the Participant under the Award Agreement.

SECTION 7. Adjustments; Change in Control; Acquisitions.

     (a) Adjustments. If there shall occur any recapitalization, stock split (including a stock split in the form of a stock dividend), reverse stock split, merger, combination, consolidation, or other reorganization or any extraordinary dividend or other extraordinary distribution in respect of the Stock (whether in the form of cash, Stock or other property), or any split-up, spin-off, extraordinary redemption, or exchange of outstanding Stock, or there shall occur any other similar corporate transaction or event in respect of the Stock, or a sale of substantially all the assets of the Corporation as an entirety, then the Committee shall, in the manner and to the extent, if any, as it deems appropriate and equitable to the Participants and consistent with the terms of this Plan, and taking into consideration the effect of the event on the holders of the Stock:

     (1) proportionately adjust any or all of:

     (A) the number and type of shares of Stock and Share Units which thereafter may be made the subject of Awards (including the specific maxima and numbers of shares of Stock or Share Units set forth elsewhere in this Plan),

     (B) the number and type of shares of Stock, other property, Share Units or cash subject to any or all outstanding Awards,

     (C) the grant, purchase or exercise price, or conversion ratio of any or all outstanding Awards, or of the Stock, other property or Share Units underlying the Awards,

     (D) the securities, cash or other property deliverable upon exercise or conversion of any or all outstanding Awards,

     (E) subject to Section 4(b), the performance targets or standards appropriate to any outstanding Performance-Based Awards, or

     (F) any other terms as are affected by the event; and/or

     (2) provide for:

     (A) an appropriate and proportionate cash settlement or distribution, or

11

     (B) the substitution or exchange of any or all outstanding Awards, or the cash, securities or property deliverable on exercise, conversion or vesting of the Awards.

     Notwithstanding the foregoing, in the case of an Incentive Stock Option, no adjustment shall be made which would cause this Plan to violate Section 424(a) of the Code or any successor provisions thereto, without the written consent of the Participant adversely affected thereby. The Committee shall act prior to an event described in this paragraph (a) (including at the time of an Award by means of more specific provisions in the Award Agreement) if deemed necessary or appropriate to permit the Participant to realize the benefits intended to be conveyed by an Award in respect of the Stock in the case of an event described in paragraph (a).

     (b) Change in Control. The Committee may, in the Award Agreement, provide for the effect of a Change in Control on an Award. Such provisions may include, but are not limited to any one or more of the following with respect to any or all Awards: (i) the specific consequences of a Change in Control on the Awards; (ii) a reservation of the Committee’s right to determine in its discretion at any time that there shall be full acceleration or no acceleration of benefits under the Awards; (iii) that only certain or limited benefits under the Awards shall be accelerated; (iv) that the Awards shall be accelerated for a limited time only; or (v) that acceleration of the Awards shall be subject to additional conditions precedent (such as a termination of employment following a Change in Control).

     In addition to any action required or authorized by the terms of an Award, the Committee may take any other action it deems appropriate to ensure the equitable treatment of Participants in the event of a Change in Control, including but not limited to any one or more of the following with respect to any or all Awards: (i) the acceleration or extension of time periods for purposes of exercising, vesting in, or realizing gain from, the Awards; (ii) the waiver of conditions on the Awards that were imposed for the benefit of the Corporation, (iii) provision for the cash settlement of the Awards for their equivalent cash value, as determined by the Committee, as of the date of the Change in Control; or (iv) such other modification or adjustment to the Awards as the Committee deems appropriate to maintain and protect the rights and interests of Participants upon or following the Change in Control. The Committee also may accord any Participant a right to refuse any acceleration of exercisability, vesting or benefits, whether pursuant to the Award Agreement or otherwise, in such circumstances as the Committee may approve.

     Notwithstanding the foregoing provisions of this Section 7(b) or any provision in an Award Agreement to the contrary, if any Award to any Insider is accelerated to a date that is less than six months after the date of the Award, the Committee may prohibit a sale of the underlying Stock (other than a sale by operation or law in exchange for or through conversion into other securities), and the Corporation may impose legend and other restrictions on the Stock to enforce this prohibition.

12

     (c) Change in Control Definition. For purposes of this Plan, with respect to any Award other than an Award issued pursuant to an Award Agreement that separately defines the term “change in control,” a change in control shall include and be deemed to occur upon the following events:

     (1) The acquisition by any person or group (including a group within the meaning of Section 13(d)(3) or 14(d)(2) of the Exchange Act), other than the Corporation or any of its Subsidiaries, of beneficial ownership (within the meaning of Rule 13d-3 under the Exchange Act) of a majority of the combined voting power of the Corporation’s then outstanding voting securities, other than by any employee benefit plan maintained by the Corporation;

     (2) The sale of all or substantially all of the assets of the Corporation or of L-3 Communications Corporation or any successor thereto;

     (3) The election, including the filling of vacancies, during any period of 24 months or less, of 50 percent or more, of the members of the Board, without the approval of Continuing Directors, as constituted at the beginning of such period. “Continuing Directors” shall mean any director of the Company who either (i) is a member of the Board on the date of grant of the relevant Award, or (ii) is nominated for election to the Board by a majority of the Board which is comprised of Directors who were, at the time of such nomination, Continuing Directors; or

     (4) In the Committee’s sole discretion on a case-by-case basis and solely with respect to Awards granted to Employees of a Subsidiary of the Corporation, or of a business unit or division of the Corporation or such Subsidiary, (i) the sale of all or substantially all of the assets of such Subsidiary, business unit or division or (ii) the sale (including without limitation by way of merger) of a majority of the combined voting power of such Subsidiary’s then outstanding voting securities.

     (d) Business Acquisitions. Awards may be granted under this Plan on the terms and conditions as the Committee considers appropriate, which may differ from those otherwise required by this Plan to the extent necessary to reflect a substitution for or assumption of stock incentive awards held by employees of other entities who become employees of the Corporation or a Subsidiary as the result of a merger of the employing entity with, or the acquisition of the property or stock of the employing entity by, the Corporation or a Subsidiary, directly or indirectly.

SECTION 8. Administration.

     (a) Committee Authority and Structure. This Plan and all Awards granted under this Plan shall be administered by the Compensation Committee of the Board or such other committee of the Board or subcommittee of the

13

Compensation Committee as may be designated by the Board and constituted so as to permit this Plan to comply with the disinterested administration requirements of Rule 16b-3 under the Exchange Act and the “outside director” requirement of Code Section 162(m). The members of the Committee shall be designated by the Board. A majority of the members of the Committee (but not fewer than two) shall constitute a quorum. The vote of a majority of a quorum or the unanimous written consent of the Committee shall constitute action by the Committee.

     (b) Selection and Grant. The Committee shall have the authority to determine the individuals (if any) to whom Awards will be granted under this Plan, the type of Award or Awards to be made, and the nature, amount, pricing, timing, and other terms of Awards to be made to any one or more of these individuals, subject to the terms of this Plan.

     (c) Construction and Interpretation. The Committee shall have the power to interpret and administer this Plan and Award Agreements, and to adopt, amend and rescind related rules and procedures. All questions of interpretation and determinations with respect to this Plan, the number of shares of Stock, Stock Appreciation Rights, or units or other Awards granted, and the terms of any Award Agreements, the adjustments required or permitted by Section 7, and other determinations hereunder shall be made by the Committee and its determination shall be final and conclusive upon all parties in interest. In the event of any conflict between an Award Agreement and any non-discretionary provisions of this Plan, the terms of this Plan shall govern.

     (d) Express Authority to Change Terms of Awards. The Committee may, at any time, alter or amend any or all Award Agreements under this Plan in any manner that would be authorized for a new Award under this Plan, including but not limited to any manner set forth in Section 9 (subject to any applicable limitations thereunder), except that no amendment or cancellation of an Award may effect a Repricing of such Award, except in connection with an adjustment pursuant to Section 7. A “Repricing” means any of the following: (i) changing the terms of an Award to lower its exercise price or base price, (ii) cancelling an Award with an exercise price or base price in exchange for other Awards with a lower exercise price or base price, or (iii) cancelling an Award with an exercise price or base price at a time when such price is equal to or greater than the Fair Market Value of the underlying Stock in exchange for other Awards, cash or property. Without limiting the Committee’s authority under this plan (including Sections 7 and 9), but subject to any express limitations of this Plan (including the prohibitions on Repricing set forth in this Section 8(d)), the Committee shall have the authority to accelerate the exercisability or vesting of an Award, to extend the term or waive early termination provisions of an Award (subject to the maximum ten-year term under Section 6(a)(5)), and to waive the Corporation’s rights with respect to an Award or restrictive conditions of an Award (including forfeiture conditions), in any case in such circumstances as the Committee deems appropriate.

14

     (e) Rule 16b-3 Conditions; Bifurcation of Plan. It is the intent of the Corporation that this Plan and Awards hereunder satisfy and be interpreted in a manner, that, in the case of Participants who are or may be Insiders, satisfies any applicable requirements of Rule 16b-3, so that these persons will be entitled to the benefits of Rule 16b-3 or other exemptive rules under Section 16 under the Exchange Act and will not be subjected to avoidable liability thereunder as to Awards intended to be entitled to the benefits of Rule 16b-3. If any provision of this Plan or of any Award would otherwise frustrate or conflict with the intent expressed in this Section 8(e), that provision to the extent possible shall be interpreted and deemed amended so as to avoid such conflict. To the extent of any remaining irreconcilable conflict with this intent, the provision shall be deemed disregarded as to Awards intended as Rule 16b-3 exempt Awards. Notwithstanding anything to the contrary in this Plan, the provisions of this Plan may at any time be bifurcated by the Board or the Committee in any manner so that certain provisions of this Plan or any Award Agreement intended (or required in order) to satisfy the applicable requirements of Rule 16b-3 are only applicable to Insiders and to those Awards to Insiders intended to satisfy the requirements of Rule 16b-3.

     (f) Delegation and Reliance. The Committee may delegate to the officers or employees of the Corporation the authority to execute and deliver those instruments and documents, to do all acts and things, and to take all other steps deemed necessary, advisable or convenient for the effective administration of this Plan in accordance with its terms and purpose, except that the Committee may not delegate any discretionary authority to grant or amend an award or with respect to substantive decisions or functions regarding this Plan or Awards as these relate to the material terms of Performance-Based Awards to Executive Officers or to the timing, eligibility, pricing, amount or other material terms of Awards to Insiders. In making any determination or in taking or not taking any action under this Plan, the Board and the Committee may obtain and may rely upon the advice of experts, including professional advisors to the Corporation. No director, officer, employee or agent of the Corporation shall be liable for any such action or determination taken or made or omitted in good faith.

     (g) Exculpation and Indemnity. Neither the Corporation nor any member of the Board of Directors or of the Committee, nor any other person participating in any determination of any question under this Plan, or in the interpretation, administration or application of this Plan, shall have any liability to any party for any action taken or not taken in good faith under this Plan or for the failure of an Award (or action in respect of an Award) to satisfy Code requirements as to incentive stock options or to realize other intended tax consequences, to qualify for exemption or relief under Rule 16b-3 or to comply with any other law, compliance with which is not required on the part of the Corporation.

SECTION 9. Amendment and Termination of this Plan.

15

     The Board of Directors may at any time amend, suspend or discontinue this Plan, subject to any stockholder approval that may be required under applicable law. Notwithstanding the foregoing, no such action by the Board or the Committee shall, in any manner adverse to a Participant other than as expressly permitted by the terms of an Award Agreement, affect any Award then outstanding and evidenced by an Award Agreement without the consent in writing of the Participant or a Beneficiary, a Participant’s family member or a trust (or similar estate planning entity) established for the benefit of a Participant and/or one or more of the Participant’s family members entitled to an Award. Notwithstanding the above, any amendment that would (i) materially increase the benefits accruing to any Participant or Participants hereunder, (ii) materially increase the aggregate number of shares of Stock, Share Units or other equity interest(s) that may be issued hereunder, or (iii) materially modify the requirements as to eligibility for participation in this Plan, shall be subject to shareholder approval.

SECTION 10. Miscellaneous.

     (a) Unfunded Plans. This Plan shall be unfunded. Neither the Corporation nor the Board of Directors nor the Committee shall be required to segregate any assets that may at any time be represented by Awards made pursuant to this Plan. Neither the Corporation, the Committee, nor the Board of Directors shall be deemed to be a trustee of any amounts to be paid or securities to be issued under this Plan.

     (b) Rights of Employees.

     (1) No Right to an Award. Status as an Employee shall not be construed as a commitment that any one or more Awards will be made under this Plan to an Employee or to Employees generally. Status as a Participant shall not entitle the Participant to any additional Award.

     (2) No Assurance of Employment. Nothing contained in this Plan (or in any other documents related to this Plan or to any Award) shall confer upon any Employee or Participant any right to continue in the employ or other service of the Corporation or any Subsidiary or constitute any contract (of employment or otherwise) or limit in any way the right of the Corporation or any Subsidiary to change a person’s compensation or other benefits or to terminate the employment or services of a person with or without cause.

     (c) Effective Date; Duration. This Plan has been adopted by the Board of Directors of the Corporation. This Plan shall become effective upon and shall be subject to the approval of the stockholders the Corporation. This Plan shall remain in effect until any and all Awards under this Plan have been exercised, converted or terminated under the terms of this Plan and applicable Award Agreements. Notwithstanding the foregoing, no Award may be granted under this Plan after

16

April 29, 2018; provided, however, that any Award granted prior to such date may be amended after such date in any manner that would have been permitted hereunder prior to such date.

     (d) Compliance with Laws. This Plan, Award Agreements, and the grant, exercise, conversion, operation and vesting of Awards, and the issuance and delivery of shares of Stock and/or other securities or property or the payment of cash under this Plan, Awards or Award Agreements, are subject to compliance with all applicable federal and state laws, rules and regulations (including but not limited to state and federal insider trading, registration, reporting and other securities laws and federal margin requirements) and to such approvals by any listing, regulatory or governmental authority as may be necessary or, in the opinion of counsel for the Corporation, advisable in connection therewith. Any securities delivered under this Plan shall be subject to such restrictions (and the person acquiring such securities shall, if requested by the Corporation, provide such evidence, assurance and representations to the Corporation as to compliance with any of such restrictions) as the Corporation may deem necessary or desirable to assure compliance with all applicable legal requirements.

     (e) Section 409A. Notwithstanding other provisions of the Plan or any Award Agreements thereunder, no Award shall be granted, deferred, accelerated, extended, paid out or modified under this Plan in a manner that would result in the imposition of an additional tax under Section 409A of the Code upon a Participant. In the event that it is reasonably determined by the Board or Committee that, as a result of Section 409A of the Code, payments in respect of any Award under the Plan may not be made at the time contemplated by the terms of the Plan or the relevant Award agreement, as the case may be, without causing the Participant holding such Award to be subject to taxation under Section 409A of the Code, the Company will make such payment on the first day that would not result in the Participant incurring any tax liability under Section 409A of the Code; which, if the Participant is a “specified employee” within the meaning of the Section 409A, shall be the first day following the six-month period beginning on the date of Participant’s termination of Employment.

     (f) Applicable Law. This Plan, Award Agreements and any related documents and matters shall be governed by, and construed in accordance with, the laws of the State of New York and applicable Federal law.

     (g) Non-Exclusivity of Plan. Nothing in this Plan shall limit or be deemed to limit the authority of the Corporation, the Board or the Committee to grant awards or authorize any other compensation, with or without reference to the Stock, under any other plan or authority.
