All of the Acquisitions described above are included in our consolidated balance sheet as of June 30, 2002, and therefore, an unaudited pro forma condensed consolidated balance sheet is not provided. The pro forma statements of operations do not include an extraordinary pre-tax charge of $16.2 million ($9.9 million after-tax) related to the repurchase and redemption of our $225.0 million 10 3/8% Senior Subordinated Notes due 2007. The extraordinary charge includes the call premium of 5.188% or approximately $11.7 million and fees and other expenses of approximately $4.5 million, including the write-off of unamortized deferred debt issue costs relating to the $225.0 million 10 3/8% Senior Subordinated Notes due 2007. The extraordinary charge is not included in the pro forma statements of operations because it is not a component of income (loss) from continuing operations. However, had the repurchase and redemption occurred on January 1, 2001, the extraordinary charge would have reduced pro forma basic earnings per common share by $0.11 and pro forma diluted earnings per common share by $0.10 for the six months ended June 30, 2001 and for the year ended December 31, 2001. The pro forma adjustments related to our Acquisitions are based on preliminary purchase prices and purchase price allocations. Actual adjustments will be based on final purchase prices, audited historical net assets for the Acquisitions, and final appraisals and other analyses of fair values of contracts in process, inventories, estimated costs in excess of billings to complete contracts in process, identifiable intangibles, pension and postretirement benefit obligations and deferred tax assets and liabilities, which will be completed after we obtain and review all of the data required for the acquired assets and liabilities and complete our valuations of them. Differences between the preliminary and final purchase price allocations could have a material impact on our results of operations and financial position. The unaudited pro forma condensed consolidated statement of operations does not reflect any cost savings that we believe would have resulted had the Acquisitions occurred on January 1, 2001. The unaudited pro forma condensed consolidated financial information should be read in conjunction with (1) our unaudited condensed consolidated financial statements for the six months ended June 30, 2002 and 2001, and our audited consolidated financial statements for the year ended December 31, 2001 incorporated by reference in this prospectus; and (2) the audited combined financial statements of AIS for the year ended December 31, 2001 incorporated by reference in this prospectus. The other historical statement of operations data for the Acquisitions are based on unaudited financial statement data not included or incorporated by reference herein. The unaudited pro forma condensed consolidated financial information may not be indicative of the results of operations that actually would have occurred had the Acquisitions and the Offerings been completed on January 1, 2001 or the results of our operations that may be obtained in the future. 2 UNAUDITED PRO FORMA CONDENSED CONSOLIDATED STATEMENT OF OPERATIONS FOR THE SIX MONTHS ENDED JUNE 30,

On March 8, 2002, we acquired AIS for $1,152.7 million in cash which includes $1,130.0 million for the original contract purchase price, $4.0 million for estimated acquisition costs and an increase to the contract purchase price of $18.7 million related to additional assets contributed by Raytheon to AIS. The purchase price is subject to adjustment based on the AIS closing date net tangible book value, as defined. The AIS acquisition was financed using cash on hand as well as available borrowings under our senior credit facilities and a $500.0 million senior subordinated interim loan. On June 14, 2002, we acquired the detection systems business of PerkinElmer ("PKI") for $100.0 million in cash plus acquisition costs, subject to adjustment based on closing date net working capital, as defined. During the year ended December 31, 2001, we also made the following acquisitions: o in May 2001, all the outstanding common stock of KDI Precision Products, Inc. ("KDI") for $79.4 million in cash including acquisition costs. o in May 2001, all the outstanding common stock of EER Systems, Inc. ("EER") for $119.5 million in cash including acquisition costs, and subject to an additional purchase price not to exceed $5.0 million which is contingent upon the financial performance of EER for the year ending December 31, 2002. o in November and December 2001, 70.3% of the outstanding common stock of Spar Aerospace Limited ("Spar") for $105.1 million in cash including acquisition costs.

Our historical interest income has been eliminated because the cash and cash equivalents which earned the interest income were obtained from the net proceeds from the CODES (as defined below) offering and the May 2001 Common Stock Offering (as defined below) that were assumed entirely to be used to finance the Acqusitions. Such eliminations amounted to $1.5 million for the six months ended June 30, 2002, $1.4 million for the six months ended June 30, 2001 and $3.8 million for the year ended December 31, 2001. 4. The aggregate purchase prices, including acquisition costs, for the Acquisitions of $1,739.4 million were assumed to be financed at January 1, 2001 using (1) borrowings under our senior credit facilities of $445.6 million, (2) borrowings of $500.0 million under the senior subordinated interim loan, (3) cash on hand of $32.7 million, (4) the net proceeds from the sale of $420.0 million of 4% Senior Subordinated Convertible Contingent Debt Securities due September 15, 2011 ("CODES") in October and November of 2001, which amounted to $407.5 million, and (5) the net proceeds from our public offering of 9,150,000 shares of our common stock in May 2001 (the "May 2001 Common Stock Offering") which amounted to $353.6 million. The borrowings under the senior credit facilities and the senior subordinated interim loan that we made to finance the AIS acquisition were included in our historical results of operations effective March 1, 2002. The adjustments to our historical interest expense for the six months ended June 30, 2002 and 2001 and the year ended December 31, 2001 to give effect to the financing of the Acquisitions are presented below.

The average prevailing interest rates on the senior credit facilities would have been 4.86% for the six months ended June 30, 2002, 7.11% for the six months ended June 30, 2001 and 6.57% for the year ended December 31, 2001. The average prevailing interest rates on the senior subordinated interim loan would have been 5.36% for the six months ended June 30, 2002, 8.65% for the six months ended June 30, 2001, and 7.59% for the year ended December 31, 2001. 7 NOTES TO UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) 5. Assuming the offering of the senior subordinated notes by L-3 Communications and the concurrent sale of common stock of 14,000,000 million shares were completed on January 1, 2001, the net aggregate proceeds from the Offerings of $1,499.4 million, after deductions for underwriting commissions and discounts and other offering expenses totaling $43.0 million, would have been applied to repay all of the borrowings under the senior subordinated interim loan of $500.0 million, repurchase and redeem our 10 3/8% Senior Subordinated Notes due 2007, repay $445.6 million of borrowings outstanding under the senior credit facilities and $316.4 million would have been invested in cash and cash equivalents. Total interest expense after the pro forma adjustments for our Acquisitions but prior to the Offerings amounted to $65.8 million for the six months ended June 30, 2002, $92.9 million for the six months ended June 30, 2001, and $168.8 million for the year ended December 31, 2001. As a result of the Offerings, total pro forma interest expense would have decreased by $6.8 million for the six months ended June 30, 2002, $20.0 million for the six months ended June 30, 2001 and $32.4 million for the year ended December 31, 2001.

(10.8) (15.8) (29.3) ------- ------- ------- Total adjustments to pro forma interest expense ................................... $ (6.8) $ (20.0) $ (32.4) ======= ======= ======= ---------- (a) The adjustments to pro forma interest expense for the pro forma adjustments for borrowings under the senior credit facilities and senior subordinated interim loan are based on the average prevailing interest rates that L-3 would have paid on those borrowings for the periods presented had such borrowings been outstanding at the beginning of each of the periods presented. The average prevailing interest rates on the senior credit facilities would have been 4.86% for the six months ended June 30, 2002, 7.11% for the six months ended June 30, 2001 and 6.57% for the year ended December 31, 2001. The average prevailing interest rates on the senior subordinated interim loan would have been 5.36% for the six months ended June 30, 2002, 8.65% for the six months ended June 30, 2001, and 7.59% for the year ended December 31, 2001. The pro forma statements of operations do not reflect interest income on the $316.4 million pro forma cash balance at January 1, 2001 that we would have had after the Offerings. 6. The pro forma adjustments for our Acquisitions and the Offerings were all tax-effected, as appropriate, using an estimated statutory (federal and state) tax rate of 40.0%. The pro forma 8 NOTES TO UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) adjustments also include an income tax (benefit) provision (($0.8) million for the six months ended June 30, 2001 and $1.1 million for the year ended December 31, 2001) to record the aggregate income tax expense for the historical results of operations of KDI, EER, BT Fuze and SY to the statutory income tax rate of 40.0% that they would have incurred had we acquired them on January 1, 2001, but did not because they were not subject to income tax prior to their acquisition by us. 7. Our diluted weighted average shares outstanding and diluted earnings per share give effect to the assumed conversion of the 7,361,964 shares issuable upon the conversion of $300.0 million of our 51/4% Convertible Senior Subordinated Notes due 2009 (the "Convertible Notes"). The assumed conversion results in the addition of $5.2 million of after-tax interest expense savings to reported net income for the six months ended June 30, 2002 and $10.5 million for the year ended December 31, 2001 for the purposes of calculating diluted earnings per share. The assumed conversion of the Convertible Notes for the six months ended June 30, 2001 were anti-dilutive, and therefore, their conversion was not assumed for that period. 8. The pro forma statement of operations for the six months ended June 30, 2001 includes the following unaudited historical financial data for our Acquisitions.

Adjustments to costs and expenses relating to the Acquisitions are presented in the table below: SIX MONTHS ENDED YEAR ENDED JUNE 30, 2001 DECEMBER 31, 2001 --------------- ------------------ (IN MILLIONS) Eliminate historical goodwill amortization for AIS, EMG, Spar and PKI(a) .................. $ (15.5) $ (30.7) Increase to goodwill amortization for KDI and EER for higher goodwill recorded by L-3 than their historical amounts of goodwill(a) .............. 0.7 0.7 ------- ------- Total pro forma adjustments to costs and expenses .................................... $ (14.8) $ (30.0) ======= ======= ---------- (a) In accordance with Statement of Financial Accounting Standards ("SFAS") No. 142, no goodwill amortization expenses would have been recorded by us in 2001 for the acquisitions of EMG, Spar, BT Fuze, SY, AIS and PKI because these acquisitions were completed after June 30, 2001. Additionally, in accordance with SFAS No. 142, effective January 1, 2002 goodwill amortization is no longer being recorded for any of the Acquisitions. The assets and liabilities recorded in connection with the purchase price allocations for the Acquisitions are all based upon preliminary estimates of fair values for contracts in process, estimated costs in excess of billings to complete contracts in process, inventories, identifiable intangibles and deferred taxes. Actual adjustments will be based on the final purchase prices and final appraisals and other analyses of fair values which are in process. With the exception of the AIS acquisition, we do not expect the differences between the preliminary and final purchase price allocations for the acquisitions to be material. Material differences between the preliminary and final purchase price allocations for the AIS acquisition could result from the valuation of contracts in process, estimated costs in excess of billings to complete contracts in process, identifiable intangibles, deferred income taxes and pension and postretirement benefits and other items. A review of the contracts in process and identifiable intangible assets included in the AIS acquisition is being performed. All of the data required to prepare this review and the related valuations is not currently available and at this time it is not practicable to reasonably estimate these valuations. In addition, no adjustment has been made to contracts in process which will be valued at their estimated contract prices less the estimated costs to complete and an allowance for a normal profit on the effort to complete such contracts. Although the final purchase price allocation for the contracts in process, estimated costs in excess of billings to complete contracts in process, deferred taxes and pension and postretirement benefits of AIS could materially affect the amount of goodwill recorded for AIS, such final purchase price allocations are not expected to have a material effect on our results of operations. Furthermore, any allocation of purchase price to identifiable intangible assets with finite lives will result in additional amortization expense and a reduction to the estimated goodwill for AIS. For example, an allocation of $50.0 million to identifiable intangible assets with a 10 year life would result in an increase of $5.0 million per annum to costs and expenses and a decrease of $3.0 million per annum to income from continuing operations. 10. The pro forma adjustments for the Offerings for the six months ended June 30, 2001 and the year ended December 31, 2001 do not include an extraordinary charge of $16.2 million ($9.9 million after-tax) related to the repurchase and redemption of our $225.0 million 10 3/8% Senior Subordinated Notes due 2007. The extraordinary charge includes the call premium of 5.188% or approximately $11.7 million and fees and other expenses of approximately $4.5 million, including the write-off of the unamortized deferred debt issue costs on the $225.0 million 10 3/8% Senior Subordinated Notes due 2007. The extraordinary charge is not included in the pro forma adjustments because it is not a component of income (loss) from continuing operations. However, had the repurchase and redemption occurred on January 1, 2001, the extraordinary charge would 10 have reduced pro forma basic earnings per common share by $0.11 and pro forma diluted earnings per common share by $0.10 for the six months ended June 30, 2001 and for the year ended December 31, 2001. NOTES TO UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) 11. Our basic and diluted weighted average common shares outstanding for the six months ended June 30, 2001 were increased by 6.1 million shares, and for the year ended December 31, 2001 were increased by 3.1 million shares of common stock to give effect to the assumed completion of our May 2001 Common Stock Offering as of January 1, 2001. 12. The pro forma statement of operations for the year ended December 31, 2001 includes the following unaudited historical financial data for our Acquisitions.

(f) Includes a $1.4 million restructuring charge. (g) Includes a $3.8 million restructuring charge. The historical results of operations for KDI, EER, BT Fuze and SY do not include a provision for income taxes because they each were either an S Corporation or a Limited Liability Company and the income taxes on their income were paid by their individual stockholders rather than the entities. 11 PLAN OF DISTRIBUTION We have been advised that the distribution of the common stock by the selling stockholders may be effected from time to time in one or more transactions (which may involve block transactions): (1) on the New York Stock Exchange or such other national security exchanges on which our common stock are listed, in transactions that may include special offerings and exchange distributions pursuant to and in accordance with the rules of such exchanges, (2) in the over-the-counter market, or (3) in transactions otherwise than on such exchanges or in the over-the-counter market, or in a combination of any such transactions. Such transactions may be effected by the selling stockholders at market prices prevailing at the time of sale, at prices related to such prevailing market prices, at negotiated prices or at fixed prices. The selling stockholders may effect such transactions by selling the common stock to or through broker-dealers and such broker-dealers will receive compensation in the form of discounts or commissions from the selling stockholders and may receive commissions from the purchasers of the common stock for whom they may act as agent (which discounts or commissions from the selling stockholders or such purchasers will not exceed those customary in the type of transactions involved). Any broker-dealers that participate with the selling stockholders in the distribution of the common stock may be deemed to be "underwriters" within the meaning of the Securities Act, and any commissions or discounts received by such broker-dealers and any profit on the resale of the common stock by such broker-dealers might be deemed to be underwriting discounts and commissions under such act. Upon being notified by the selling stockholders that any material arrangement has been entered into with a broker or dealer for the sale of the common stock through a secondary distribution, or a purchase by a broker or dealer, a supplemented prospectus will be filed, if required, pursuant to Rule 424(b) under the Securities Act, disclosing: o The names of such broker-dealers; o The number of shares involved; o The price at which such shares are being sold; o The commission paid or the discounts or concessions allowed to such broker-dealer; o Where applicable, that such broker-dealers did not conduct any investigation to verify the information set out or incorporated by reference in this prospectus, as supplemented; and o Other facts material to the transaction. 12 AVAILABLE INFORMATION We are subject to the informational requirements of the Securities Exchange Act of 1934 and, in accordance therewith, file reports and other information with the SEC.

INDEMNIFICATION OF DIRECTORS AND OFFICERS. Section 145 of the Delaware General Corporation Law (the "DGCL") provides for, among other things: a. permissive indemnification for expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by designated persons, including directors and officers of a corporation, in the event such persons are parties to litigation other than stockholder derivative actions if certain conditions are met; b. permissive indemnification for expenses (including attorneys' fees) actually and reasonably incurred by designated persons, including directors and officers of a corporation, in the event such persons are parties to stockholder derivative actions if certain conditions are met; c. mandatory indemnification for expenses (including attorneys' fees) actually and reasonably incurred by designated persons, including directors and officers of a corporation, in the event such persons are successful on the merits or otherwise in defense of litigation covered by a. and b. above; and d. that the indemnification provided for by Section 145 is not deemed exclusive of any other rights which may be provided under any by-law, agreement, stockholder or disinterested director vote, or otherwise. In addition to the indemnification provisions of the DGCL described above, the Registrant's certificate of incorporation (the "Certificate of Incorporation") authorizes indemnification of the Registrant's officers and directors, subject to a case-by-case determination that they acted in good faith and in a manner they reasonably believed to be in or not opposed to the best interests of the Registrant, and in the case of any criminal proceeding, they had no reasonable cause to believe their conduct was unlawful. In the event that a Change in Control (as defined in the Certificate of Incorporation) shall have occurred, the proposed indemnitee director or officer may require that the determination of whether he met the standard of conduct be made by special legal counsel selected by him. In addition, whereas the DGCL would require court-ordered indemnification, if any, in cases in which a person has been adjudged to be liable to the Registrant, the Certificate of Incorporation also permits indemnification in such cases if and to the extent that the reviewing party determines that such indemnity is fair and reasonable under the circumstances. The Certificate of Incorporation requires the advancement of expenses to an officer or director (without a determination as to his conduct) in advance of the final disposition of a proceeding if such person furnishes a written affirmation of his good faith belief that he has met the applicable standard of conduct and furnishes a written undertaking to repay any advances if it is ultimately determined that he is not entitled to indemnification. In connection with proceedings by or in the right of the Registrant, the Certificate of Incorporation provides that indemnification shall include not only II-1 reasonable expenses, but also penalties, fines and amounts paid in settlement. Unless ordered by a court, such indemnification shall not include judgments. Under the Certificate of Incorporation, no officer or director is entitled to indemnification or advancement of expenses with respect to a proceeding brought by him against the Registrant other than a proceeding seeking or defending such officer's or director's right to indemnification or advancement of expenses. Finally, the Certificate of Incorporation provides that the Registrant may, subject to authorization on a case by case basis, indemnify and advance expenses to employees or agents to the same extent as a director or to a lesser extent (or greater, as permitted by law) as determined by the Board of Directors. The Certificate of Incorporation purports to confer upon officers and directors contractual rights to indemnification and advancement of expenses as provided therein. In addition, as permitted by the DGCL, the Registrant has entered into indemnity agreements with its directors and selected officers that provide contract rights substantially identical to the rights to indemnification and advancement of expenses set forth in the Certificate of Incorporation, as described above. The Certificate of Incorporation limits the personal liability of directors to the Registrant or its stockholders for monetary damages for breach of the duty as a director, other than liability as a director (i) for breach of duty of loyalty to the Registrant or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL (certain illegal distributions), or (iv) for any transaction for which the director derived an improper personal benefit. The Registrant maintains officers' and directors' insurance covering certain liabilities that may be incurred by officers and directors in the performance of their duties. ITEM 16.

UNDERTAKINGS. The undersigned registrants hereby undertake: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: (i) To include any prospectus required by Selection 10(a)(3) of the Securities Act of 1933; (ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in II-2 volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement. (iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement. (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrants pursuant to the foregoing provisions, or otherwise, the registrants have been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrants of expenses incurred or paid by the director, officer or controlling person of the registrants in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrants will, unless in the opinion of their counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue. II-3 SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized in the City of New York, State of New York, on September 17, 2002.
