RECORD DATE The board of directors has fixed the close of business on March 15, 2002 as the record date for the Annual Meeting (the "Record Date"). Only stockholders of record at the Record Date (the "Stockholders") are entitled to notice of and to vote at the Annual Meeting or at any adjournments thereof, in person or by proxy. At the Record Date, there were 39,608,831 shares of our common stock outstanding. This proxy statement, the accompanying proxy card and our Annual Report to stockholders are intended to be mailed on or about April 1, 2002 to each Stockholder entitled to vote at the Annual Meeting. PROXIES The proxy accompanying this proxy statement is solicited on behalf of our board of directors for use at the Annual Meeting and any adjournments of the Annual Meeting, and the expenses of solicitation of proxies will be borne by us. The solicitation will be made primarily by mail, but our officers and regular employees may also solicit proxies by telephone, telegraph, facsimile or in person. We also have retained to assist in soliciting proxies. Each holder of common stock is entitled to one vote for each share of our common stock held. The holders in person or by proxy of a majority of the common stock entitled to be voted at the Annual Meeting shall constitute a quorum. Each Stockholder may appoint a person (who need not be a shareholder) other than the persons named in the enclosed proxy to represent him or her at the meeting by completing another proper proxy. In either case, such completed proxy should be returned in the enclosed envelope provided for that purpose for delivery before the meeting or should be delivered to our Secretary at 600 Third Avenue, New York, New York 10016, not later than 5 p.m., eastern daylight time, on Monday, April 22, 2002. Any proxy delivered pursuant to this solicitation is revocable at the option of the person(s) executing the proxy upon our receipt, prior to the time the proxy is voted, of a duly executed instrument revoking it, or of a duly executed proxy bearing a later date, or in the case of death or incapacity of the person(s) executing the proxy, of written notice of such death or incapacity, or by such person(s) voting in person at the Annual Meeting. Unless revoked, all proxies representing shares entitled to vote which are delivered pursuant to this solicitation will be voted at the Annual Meeting and, where a choice has been specified on the proxy card, will be voted in accordance with such specification. WHERE A CHOICE HAS NOT BEEN SPECIFIED ON THE PROXY CARD, THE PROXY WILL BE VOTED IN ACCORDANCE WITH THE RECOMMENDATIONS OF YOUR BOARD OF DIRECTORS. Assuming a quorum is present, a majority of the shares of common stock present in person or represented by proxy at the Annual Meeting is required for the election of directors and for approval of all other items submitted to Stockholders for their consideration. Abstentions and instances where brokers are prohibited from exercising discretionary authority for beneficial owners who have not returned a proxy (so-called "broker non-votes") will be counted for purposes of determining a quorum, but will not be counted as either voting for or against any proposal. 1

VOTING BY TELEPHONE OR INTERNET Instead of submitting your vote by mail on the enclosed proxy card, you can vote by telephone or over the Internet. The telephone and Internet voting procedures, which comply with Delaware law, are designed to authenticate Stockholders' identities, to allow Stockholders to vote their shares and to confirm that their instructions have been properly recorded. Voting your proxy by mail, telephone or the Internet will not limit your right to vote at the Annual Meeting if you later decide to attend in person. If your shares are held in the name of a broker, bank or other record holder, you must obtain a proxy from the record holder as to how to vote your shares or obtain a proxy from the record holder to vote at the Annual Meeting. Stockholders with shares registered directly in their name in our stock records maintained by our transfer agent, EquiServe Trust Company, N.A., may vote their shares (1) by making a toll-free telephone call from the U.S. and Canada to EquiServe at 1-877-PRX-VOTE (1-877-779-8683), (2) by submitting their proxy over the Internet at the following address on the World Wide Web: http://www.eproxyvote.com/lll, or (3) by mailing their signed proxy card. Specific instructions to be followed by registered Stockholders are set forth on the enclosed proxy card. Proxies submitted by telephone or over the Internet as described above must be received by 5:00 p.m., eastern daylight time, on April 22, 2002. REVOCATION OF PROXIES SUBMITTED BY TELEPHONE OR INTERNET To revoke a proxy previously submitted by telephone or over the Internet, you may simply vote again at a later date, using the same procedures, in which case your later submitted vote will be recorded and your earlier vote revoked, or by attending the meeting and voting in person.

The non-affiliated directors receive annual compensation of $30,000 for service on the board of directors, of which $25,000 is paid in cash, and $5,000 is paid in shares of our common stock. In addition, non-affiliated directors receive an annual stock option grant of 1,500 shares of our common stock, which will vest in three equal annual installments.

(2) The number of shares shown includes shares that are individually or jointly owned, as well as shares over which the individual has either sole or shared investment or voting authority. (3) Share ownership does not exceed one percent of the class unless otherwise indicated. Under Rule 13d-3, certain shares may be deemed to be beneficially owned by more than one person (if, for example, persons share the power to vote or the power to dispose of the shares). In addition, shares are deemed to be beneficially owned by a person if the person has the right to acquire the shares (for example, upon exercise of an option) within 60 days of the date as of which the information is provided. In computing the percentage ownership of any person, the amount of shares outstanding is deemed to include the amount of shares beneficially owned by such person (and only such person) by reason of these acquisition rights. As a result, the percentage of outstanding shares of any person as shown in this table does not necessarily reflect the person's actual ownership or voting power with respect to the number of shares of common stock actually outstanding at March 15, 2002. (4) Robert B. Millard and Alan H. Washkowitz, each of whom is a member of our board of directors, are each a Managing Director of Lehman Brothers Inc.

REPORT OF THE AUDIT COMMITTEE The directors who serve on the audit committee are all "independent" in accordance with the New York Stock Exchange listing standards. We have reviewed and discussed with management the Company's audited financial statements as of and for the year ended December 31, 2001. 11

We have discussed with the independent auditors, PricewaterhouseCoopers LLP, the matters required to be discussed by Statement on Auditing Standards No. 61, Communication with Audit Committees, as amended, by the Auditing Standards Board of the American Institute of Certified Public Accountants. We have received and reviewed the written disclosures and the letter from PricewaterhouseCoopers LLP, required by Independence Standard No. 1, Independence Discussions with Audit Committees, as amended, by the Independence Standards Board, and have discussed with the auditors their independence. Based on the activities referred to above, we recommended to the board of directors that the financial statements referred to above be included in our Annual Report on Form 10-K for the year ended December 31, 2001. INDEPENDENT AUDITOR FEES For services rendered in 2001 by PricewaterhouseCoopers LLP, our independent auditors, we incurred the following fees: o Audit Fees (for the audit of the 2001 financial statements and quarterly reviews) -- $1,087,000 o Financial Information Systems Design and Implementation Fees --$0 o All Other Fees ($1,510,036 for tax services and $1,155,343 for other audit services, including acquisition audits, review of SEC registrations, benefit plan and other statutory audits, and $200,000 applicable to the audit of our 2000 financial statements) -- $2,665,379 As set forth in the Audit Committee Charter, the audit committee has considered and determined that the provision of the services covered under the caption All Other Fees is compatible with maintaining the auditor's independence. COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION The compensation committee is responsible for reviewing the design of, and pay levels generated by, our compensation and benefit programs for our executive officers. The committee is also responsible for administering our stock option program. The committee is committed to ensuring an executive compensation program that supports our mission -- to maximize stockholder value. Thus, the executive compensation is structured around the following tenets: o Total compensation programs should strengthen the relationship between pay and performance by emphasizing variable, at-risk compensation that is dependent on our achievement and individual performance goals. o Management should be focused on the long-term interests of stockholders. Thus, a significant portion of the compensation opportunity should be long-term, at-risk pay in the form of stock options. o We must maintain our ability to attract, retain, and encourage the development of qualified, capable executives. Total compensation opportunities will mirror those offered by comparably sized organizations within the aerospace and defense industries -- for those positions where the labor market is not limited to these industries, we will reference broader general industry information for similarly sized organizations. The comparative group used for compensation purposes will generally be broader than the group that comprises the published industry index in the performance graph included in this proxy statement. The compensation committee believes that our competition for executive talent is not limited to the companies included in the published industry index established for comparing stockholder returns. 12

The key elements of our executive compensation program are base salary, annual incentives, and long-term compensation. These key elements are addressed separately below. BASE SALARIES The compensation committee will regularly review the base salary for the Chief Executive Officer and the President. We have established internal relationships of other senior executive positions to those of the Chief Executive Officer and the President, and base salaries for these other positions flow from those relationships. Base salaries will be targeted at the median of market levels with adjustments above or below market to recognize varying levels of responsibility, prior experience, breadth of knowledge, as well as external pay practices. Increases to base salaries will be driven primarily by individual performance. Individual performance will be evaluated based on sustained levels of individual contribution. As reflected in the Summary Compensation Table, Mr. Lanza's base salary was $750,000 in 2001, 2000 and 1999 as provided for in his employment agreement. In determining future increases to Mr. Lanza's base salary, the compensation committee will consider his individual performance as measured by short-term achievements as well as his contributions to long-term organizational success. The compensation committee will also compare Mr. Lanza's base salary to base salaries of chief executive officers among comparable companies. ANNUAL INCENTIVES The annual incentive plan is structured to provide a variable pay opportunity based on performance. Actual bonuses are based on an assessment of the participant's contributions toward organizational success. Mr. Lanza received a bonus of $750,000 in 2001. On April 30, 1997 at the time Messrs. Lanza and LaPenta entered into their respective employment agreements they were each granted a stock option on 1,142,857 shares of common stock, 50% of which vested over time and 50% of which the vesting date was determined based on our achievement of certain annual or cumulative performance targets. On April 5, 1999, in recognition of their superior performance, the compensation committee amended the option grants to Messrs. Lanza and LaPenta to eliminate the performance targets and to provide that the unvested portion of the performance options vest and become exercisable as of April 30, 2000. In determining to amend the option grants, the compensation committee also took into account the fact that the existing performance targets were no longer applicable as a result of the acquisitions completed by us in 1998 and of our ongoing acquisition activities. See "Employment Agreements." LONG-TERM INCENTIVES Long-term incentives are provided pursuant to the 1997 Plan and the 1999 Plan. Stock options will be granted at a price not less than the fair market value of our common stock on the date of grant. The ultimate value of an option grant to the recipient depends on the stockholder value created between the date of grant and the date of exercise. Option award size is based primarily on competitive practice but may also be adjusted to reflect factors such as individual and our company's performance. POLICY WITH RESPECT TO THE $1 MILLION DEDUCTION LIMIT Section 162(m) of the Internal Revenue Code generally limits the corporate deduction for compensation paid to the named executive officers to $1 million, unless certain requirements are met. The compensation committee will consider the impact of this provision when making compensation decisions. However, the compensation committee will weigh all pertinent factors to determine appropriate plan design and incentive awards. Members of the compensation committee are Robert B. Millard (Chairman), John E. Montague and Alan H. Washkowitz. 13

STOCK PERFORMANCE GRAPH The graph below compares the cumulative total return of our common stock with the cumulative total return of the Standard & Poor's 500 Composite Stock Index and a peer group index, for the period from May 19, 1998 to December 31, 2001. These figures assume that all dividends paid over the performance period were reinvested, and that the starting value of each index and the investment in our common stock was $100 on May 19, 1998. The starting point for the measurement of our common stock cumulative total return was our initial public offering price of $22.00 per share. The peer group index is composed of Alliant Techsystems Inc., General Dynamics Corporation and Northrop Grumman Corporation. The graph is not, and is not intended to be, indicative of future performance of our common stock. 14

Robert Millard, John Montague and Alan Washkowitz served as members of the compensation committee of the board of directors. None of these individuals has served us or any of our subsidiaries as an officer or employee. Messrs. Millard and Washkowitz are limited partners of Lehman Brothers Capital Partners III, L.P., which, together with Lehman Brothers Holdings, Inc. and certain of their affiliates, owned 15.9 % of our outstanding common stock as of March 12, 2001 and, as of March 15, 2002 owned less than five percent of our outstanding common stock. Pursuant to a Stockholders Agreement entered into in connection with our incorporation, Lehman Brothers Capital Partners III, L.P. and its affiliates that directly own our common stock (the "Lehman Partnership"), have the right from time to time subject to certain conditions, to require us to register under the Securities Act shares of our common stock that the Lehman Partnership holds. The Lehman Partnership has the right to request up to four demand registrations and also has piggyback registration rights. We have agreed in the Stockholders Agreement to pay expenses in connection with, among other things, (i) up to three demand registrations requested by the Lehman Partnership and (ii) any registration in which the existing stockholders participate through piggyback registration rights granted under such agreement. None of our executive officers serves as a member of the board of directors or compensation committee of any entity which has one or more executive officers serving as a member of our board of directors or compensation committee. 15

EMPLOYMENT AGREEMENTS We have entered into an employment agreement (the "Employment Agreements") effective on April 30, 1997 with each of Mr. Lanza, our Chairman and Chief Executive Officer, who will receive a base salary of $750,000 per annum and appropriate executive level benefits, and Mr. LaPenta, our President and Chief Financial Officer, who will receive a base salary of $500,000 per annum and appropriate executive level benefits. The Employment Agreements provide for an initial term of five years, which will automatically renew for one-year periods thereafter, unless a party thereto gives notice of its intent to terminate at least 90 days prior to the expiration of the term. We are currently negotiating the terms of a renewal of these contracts. Upon a termination without cause or resignation for good reason, we will be obligated, through the end of the term, to (i) continue to pay the base salary and (ii) continue to provide life insurance and medical and hospitalization benefits comparable to those provided to other senior executives; provided, however, that any such coverage shall terminate to the extent that Mr. Lanza or Mr. LaPenta, as the case may be, is offered or obtains comparable benefits coverage from any other employer. The Employment Agreements provide for confidentiality during employment and at all times thereafter. There is also a noncompetition and non-solicitation covenant which is effective during the employment term and for one year thereafter; provided, however, that if the employment terminates following the expiration of the initial term, the noncompetition covenant will only be effective during the period, if any, that we pay the severance described above. We have granted each of Messrs. Lanza and LaPenta nonqualified options to purchase, at $6.47 per share, 1,142,857 shares of our common stock. In each case, half of the options were structured as "time options" and half were structured initially as "performance options," collectively referred to herein as the options. The time options became exercisable with respect to 20% of the shares subject to the time options on each of March 2, 1998, April 30, 1999 and April 30, 2000 and will become exercisable with respect to an additional 20% of the shares subject to the time options on each of April 30, 2001 and 2002 if employment continues through and including these dates. The performance options were initially structured to become exercisable nine years after the grant date, but became exercisable earlier if certain targets for our earnings before interest, income taxes, depreciation and amortization were achieved. On April 5, 1999, we amended the performance options to eliminate the performance target acceleration provisions and to provide that the unvested portion of the performance options vest and become exercisable as of April 30, 2000. The option term is ten years through April 30, 2007; except that if (i) the option-holder is fired for cause or resigns without good reason, the options will expire upon termination of employment or (ii) the option-holder is fired without cause, resigns for good reason, dies, becomes disabled or retires, the options will expire one year after termination of employment. Unexercisable options will terminate upon termination of employment, unless acceleration is expressly provided for. Upon a change of control, we may terminate the options, so long as the option-holders are cashed out or permitted to exercise their options prior to this change of control. We also have entered into a split-dollar life insurance agreement with Mr. LaPenta. Under the split-dollar agreement, we own and pay the premiums on the life insurance policy, and Mr. LaPenta has the right to designate a beneficiary to receive a fixed portion of the policy death benefit. The balance of the death benefit will be payable to us as a recovery of our investment. PENSION PLAN TABLE The following table shows the estimated annual pension benefits payable under the L-3 Communications Corporation Pension Plan and Supplemental Executive Retirement Plan to a covered participant upon retirement at normal retirement age (65), based on the career average compensation (salary and bonus) and years of credited service with us.

LaPenta and Strianese, years of credited service as an employee of Loral and Lockheed Martin) for each of the following persons were: Mr. Lanza, $1,250,000 and five years; Mr. LaPenta, $945,577 and 30 years; Mr. Strianese, $480,000 and 12 years; Mr. Cambria, $460,000 and five years; and Mr. Schafer, $423,320 and three years. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS As of March 15, 2002 the Lehman Partnership owned 4.4% of our common stock; and prior to their sale of our common stock pursuant to Rule 144A on September 17, 2001, the Lehman Partnership beneficially owned more than five percent of our common stock. STOCKHOLDERS AGREEMENT In connection with our incorporation we, Lehman Brothers Capital Partners III, L.P. and certain of its affiliates, Messrs. Lanza and LaPenta and Lockheed Martin entered into the Stockholders Agreement, which terminated upon the completion of our initial public offering and upon the sale of our common stock to less than 10% of our outstanding common stock, except for the terms relating to: o registration rights; and o the standstill agreement by Lockheed Martin. Pursuant to the Stockholders Agreement, at this time Messrs. Lanza and LaPenta and the Lehman Partnership have the right, subject to certain conditions, to require L-3 Communications Holdings to register their shares of our common stock under the Securities Act of 1933. The Lehman Partnership has four demand rights and each of Messrs. Lanza and LaPenta has one demand registration right. Lockheed Martin sold all of its shares of our common stock in 1999. In addition, the Stockholders Agreement also provides some existing stockholders with piggyback registration rights. The Stockholders Agreement provides, among other things, that we will pay expenses incurred in connection with: o up to three demand registrations requested by the Lehman Partnership and the two demand registrations requested by each of Messrs. Lanza and LaPenta; and o any registration in which those parties participate through piggyback registration rights granted under the agreement. The Lehman Partnership sold 2.0 million of their shares of our common stock through the exercise of their piggyback registration rights in our February 1999 common stock offering. Under the Stockholders Agreement, Lockheed Martin is subject to a standstill arrangement that expires on April 30, 2002, which generally prohibits its share ownership percentage in us, if any, from exceeding 34.9%. 17

TRANSACTIONS WITH AFFILIATES One provision of the Stockholders Agreement which expired after the Lehman Partnership no longer owned 10% of our common stock, gave Lehman Brothers Inc. the exclusive right to provide investment banking services to us, other than in connection with cash acquisitions undertaken by us, through April 2002. Over the past three years, Lehman Brothers Inc. has entered into various transactions with us and our subsidiaries. As required by the Stockholders Agreement, all fees paid in connection with such transactions and services were mutually agreed upon and, in our opinion, based on similar transactions and practices in the investment banking industry. We believe that all of these transactions were entered into on terms and conditions at least as favorable to us as they would have been had we entered into these transactions with other investment banks. CAPITAL MARKETS SERVICES In May 1998, Lehman Brothers Inc. acted as one of several initial purchasers and placement agents of $180.0 million of 8-1/2% Senior Subordinated Notes due 2008 issued by our subsidiary, L-3 Communications. In May 1998, Lehman Brothers Inc. acted as lead underwriter of our common stock we sold in our initial public offering. Lehman Brothers Inc. also acted as one of several initial purchasers and placement agents of $200.0 million of 8% Senior Subordinated Notes due 2008 issued by L-3 Communications in December 1998. In February 1999, Lehman Brothers Inc. acted as lead underwriter of the 5.0 million shares we sold in a follow-on public offering. Additionally, as part of that transaction, the Lehman Partnership sold 6.5 million shares of their shares of our common stock in a secondary public offering. In November and December 2000, Lehman Brothers Inc. was the sole initial purchaser of $300.0 million of our 5.25% Convertible Senior Subordinated Notes due 2009. In October 2001, Lehman Brothers Inc. acted as one of several initial purchasers of $420.0 million of our 4% Senior Subordinated Convertible Contingent Debt Securities due 2011. In each of these financing transactions, Lehman Brothers Inc. received customary fees, underwriting discounts and commissions. In addition, Lehman Brothers Inc. has been engaged as joint book running manager and/or joint book running initial purchaser of a contemplated offering of debt securities to replace our bridge loan facility entered into in March 2002 in connection with the Raytheon Acquisition, as defined below. MERGER AND ACQUISITIONS ADVISORY SERVICES In January 1999, Lehman Brothers Inc. acted as our advisor in connection with our acquisition of Microdyne Corporation. In April 1999, Lehman Brothers Inc. acted as our advisor in connection with our acquisition of Aydin Corporation. In 2002, Lehman Brothers Inc., acted as our advisor in connection with the acquisition of all of the assets of Aircraft Integration Systems, a division of Raytheon Company (the "Raytheon Acquisition"). For these services, Lehman Brothers Inc. received customary fees. SENIOR CREDIT FACILITIES In May 1998, Lehman Brothers Inc. acted as joint lead arranger and joint book manager and Lehman Commercial Paper Inc., an affiliate of Lehman Brothers Inc., acted as documentation agent, syndicate agent and lender in connection with two of L-3 Communications' senior credit facilities. In connection with those transactions both Lehman Brothers Inc. and Lehman Commercial Paper Inc. received customary fees and interest. In connection with L-3 Communications' $300.0 million 364-day revolving senior credit facility entered into in April 2000, Lehman Brothers Inc. acted as joint lead arranger and joint book manager and Lehman Commercial Paper Inc. acted as documentation agent, syndicate agent and lender. L-3 Communications entered into its senior credit facilities after arms-length negotiations and on the same terms with all of the other parties thereunder. During the twelve-month period ended February 28, 2002 Lehman Brothers Inc. and Lehman Commercial Paper Inc. received interest payments and fees under these senior credit facilities totaling approximately $ million. In connection with the Raytheon Acquisition, Lehman Brothers Inc. acted as joint book running manager and joint lead arranger and Lehman Commercial Paper Inc. acted as administrative agent with respect to our bridge loan facility entered into in March 2002. In connection with those transactions both Lehman Brothers Inc. and Lehman Commercial Paper Inc. received customary fees and interest. SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE Section 16(a) of the Securities Exchange Act of 1934 requires our officers and directors, and persons who own more than 10% of a registered class of our equity securities, to file reports of ownership and changes in ownership with the SEC and the NYSE. Officers, directors and greater than 10% shareholders are required by SEC regulation to furnish us with copies of all Section 16(a) forms they file. All Section 16(a) forms required to be filed were filed on a timely basis. 18

PROPOSAL 2. INCREASING THE AUTHORIZED COMMON AND PREFERRED STOCK On February 5, 2002, subject to stockholder approval, the Board of Directors authorized an amendment to our Amended and Restated Certificate of Incorporation to increase the number of authorized shares of Common Stock from one hundred million (100,000,000) shares to three hundred million (300,000,000) shares and the number of authorized shares of our preferred stock ("Preferred Stock"), from twenty-five million (25,000,000) to fifty million (50,000,000) shares. If approved by the stockholders, the first paragraph of Section 4 of our Amended and Restated Certificate of Incorporation would be amended to provide as follows: "Fourth: The total number of shares of all classes of stock which the Corporation shall have the authority to issue is 350,000,000 shares, consisting of 300,000,000 shares of Common Stock, par value $.01 per share (the "Common Stock") and 50,000,000 share of preferred stock, par value $0.01 per share (the "Preferred Stock"). Set forth below with respect to each class of stock of the Corporation is a statement of the voting powers and the designations, preferences, rights, qualifications, limitations and restrictions thereof:" We are currently authorized to issue 100,000,000 shares of Common Stock. As of the Record Date, 39,608,831 shares of Common Stock were issued and outstanding, and 15,392,774 shares of Common stock were reserved for the (1) potential conversion of our convertible notes and convertible contingent debt securities into shares of Common Stock, (2) issuance upon exercise of outstanding stock options, (3) options that may be granted in the future under our stock option plan, and (4) the issuance of Common Stock pursuant to our employee stock purchase plan. Accordingly, there are only 44,998,395 shares of Common Stock available for issuance. The Company is currently authorized to issue 25,000,000 shares of Preferred Stock. As of the Record Date, no shares of preferred stock were issued and outstanding. The Board of Directors believes that it is advisable and in our best interest and in the best interest of our stockholders to have available authorized but unissued shares of Common Stock and Preferred Stock in an amount adequate to provide for our future financing needs. The additional shares will be available for issuance from time to time in the discretion of the Board of Directors, normally without further stockholder action (except as may be required for a particular transaction by applicable law, requirements of regulatory agencies or by New York Stock Exchange rules), for any proper corporate purpose including, among other things, stock splits, stock dividends, future acquisitions of property or securities of other corporations, convertible debt financing and equity financings. As previously announced, we intend to finance part of the Raytheon Acquisition with the sale of our Common Stock, which if such sale is successfully completed, will use a portion of our authorized but unissued shares of Common Stock. As we are not contemplating offerings of the Preferred Stock in the proximate future, the terms of such securities have not been determined. The rights and preferences of Preferred Stock, such as dividends or interest rates, conversion prices, voting rights, liquidation preferences, redemption prices, maturity dates and similar matters, will be determined by the Board of Directors, without further authorization of the stockholders. No stockholder has any preemptive rights regarding future issuance of any shares of Common Stock and Preferred Stock. We have no present plans, understandings or agreements for the issuance or use of the proposed additional shares of Common Stock and Preferred Stock. Further, the Board of Directors believes that if an increase in the authorized number of shares of Common Stock and Preferred Stock were to be postponed until a specific need arose, the delay and expense incident to obtaining the approval of the Company's stockholders at that time could significantly impair the Company's ability to meet financing requirements or other objectives. The issuance of additional shares of Common Stock and Preferred Stock may have the effect of diluting the stock ownership of persons seeking to obtain control of us. Although the Board of Directors has no present intention of doing so, our authorized but unissued Common Stock and Preferred Stock could be issued in one or more transactions that would make a takeover of the Company more difficult or costly, and less likely. The proposed amendment to the Amended and Restated Certificate of Incorporation is not being recommended in response to any specific effort of which we are aware to obtain control of the Company, nor is the Board of Directors currently proposing to stockholders any anti-takeover measures. 19

A majority of the outstanding voting stock is required to amend our Amended and Restated Certificate of Incorporation. THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE APPROVAL OF THE AMENDMENT TO OUR AMENDED AND RESTATED CERTIFICATE OF INCORPORATION TO INCREASE THE AMOUNT OF OUR AUTHORIZED COMMON AND PREFERRED STOCK. PROPOSAL 3. SELECTION OF INDEPENDENT AUDITORS The board of directors has selected PricewaterhouseCoopers LLP to act as our independent auditors for the 2002 fiscal year, and a proposal to ratify this selection will be submitted to the Annual Meeting. PricewaterhouseCoopers LLP has acted as our independent auditors since our formation in 1997 and management believes it desirable and in our best interests to continue the employment of that firm. Representatives of PricewaterhouseCoopers LLP will be present at the Annual Meeting. Such representatives will have the opportunity to make a statement if they desire to do so, and are expected to be available to respond to appropriate questions. If the foregoing proposal is not approved by the holders of a majority of the shares represented at the Annual Meeting and voting on the proposal, the selection of independent auditors will be reconsidered by the board of directors. THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR RATIFICATION OF THE APPOINTMENT OF PRICEWATERHOUSECOOPERS LLP AS INDEPENDENT AUDITORS.
