COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION The Compensation Committee (the "Committee") of the Board of Directors has furnished the following report on executive compensation. The Committee administers the Corporation's stock option plans, makes annual recommendations to the full Board of Directors regarding the chief executive officer's salary, bonus, and equity-based compensation, and oversees the executive compensation program for the Corporation's other pension employees, including its executive officers. The Committee is composed of three independent directors who are not employees of the Corporation. COMPENSATION PHILOSOPHY The Corporation's compensation policies for executive officers are based on the belief that the interests of executives should be closely aligned with those of the Corporation's shareholders. The compensation policies are designed to achieve the following objectives: - Offer compensation opportunities that attract highly qualified executives, reward outstanding initiative and achievement, and retain the leadership and skills necessary to build long-term shareholder value. - Maintain a significant portion of executives' total compensation at risk, tied to both the annual and long-term financial performance of the Corporation and the creation of shareholder value. - Further the Corporation's short and long-term strategic goals and values by aligning compensation with business objectives and individual performance. EXECUTIVE COMPENSATION Compensation of executive officers other than the chief executive officer is determined by the chief executive officer. The Committee historically has obtained outside survey data regarding executive and senior level compensation and provided this data to the chief executive officer to assist him in making compensation decisions. Compensation for executive officers is comprised of base salary, annual cash bonuses and periodic stock option grants. Base Salary. Annual determinations of base salaries are made based on the competitive pay practices of companies in the same industry of similar size and market capitalization, the skills, performance level, and contribution to the business of the individual executives, and the needs of the Corporation. Annual Cash Incentive Awards. The Corporation's executive officers are eligible to receive annual cash bonus awards designed to motivate executives to attain short-term and longer-term corporate and individual management goals. Award levels vary depending upon the achievement of performance criteria established by the chief executive officer. The bonus criteria for each executive officer are tailored to the achievement of financial and operational goals specifically developed for that officer's area of responsibility, as well as overall corporate performance and the attainment of other individual objectives. Consequently, there is a direct link between the compensation of the executive officers and the Corporation's performance. 6 10 Long-Term Incentives. The Committee believes that stock options are an excellent vehicle for compensating its officers and employees. The Corporation provides long-term incentives through its stock option plans, a purpose of which is to create a direct link between executive compensation and increases in shareholder value. Stock options are granted at fair market value and vest in installments, generally over five years. When determining option awards for an executive officer, the Committee considers the executive's current contribution to Corporation performance, the anticipated contribution to meeting the Corporation's long-term strategic performance goals, and industry practices and norms. Long-term incentives granted in prior years and existing levels of stock ownership are also taken into consideration. Because the receipt of value by an executive officer under a stock option is dependent upon an increase in the price of the Corporation's Common Stock, this portion of the executive's compensation is directly aligned with an increase in shareholder value. CHIEF EXECUTIVE COMPENSATION The chief executive officer's compensation is comprised of base salary, annual cash incentive awards and stock option grants. In determining the base salary paid to Mr. Bertelli for the year ended June 30, 1998, the Committee considered his level of responsibility, salary increases awarded to him in the past, his experience, his potential, and compensation programs of other companies of similar size and characteristics. Annual cash bonuses and stock option grants to Mr. Bertelli are based on the attainment of individual and corporate performance targets established at the beginning of the fiscal year. The annual cash bonus and option grants to Mr. Bertelli for the fiscal year ended June 30, 1998 reflect the achievement of predetermined targets based on the Corporation's revenue, pre-tax income, and certain non-financial goals. Mr. Bertelli's base compensation increased 6%, from $260,000 during the fiscal year ended June 30, 1997 to $275,000 during the fiscal year ended June 30, 1998. Mr. Bertelli's cash bonus of $116,600 and grant of options to purchase 14,119 shares of common stock in respect of the fiscal year ended June 30, 1998, were based upon achievement of a significant portion of the pre-determined targets described above. Mr. Bertelli's cash bonus and stock option grant reflect increases in the Corporation's revenues and pre-tax profits of 32% and 88% respectively, from fiscal 1997 to fiscal 1998. In 1993, the Internal Revenue Code was amended to limit the deduction a public company is permitted for compensation paid in 1994 and thereafter to the chief executive officer and to the four most highly compensated executive officers, other than the chief executive officer. Generally, amounts paid in excess of $1,000,000 to a covered executive, other than performance-based compensation, cannot be deducted. In order to qualify as performance-based compensation under the new tax law, certain requirements must be met, including approval of the performance measures by the stockholders. The Committee intends to consider ways to maximize deductibility of executive compensation, while retaining the discretion the Committee considers appropriate to compensate executive officers at levels commensurate with their responsibilities and achievements. The foregoing report has been approved by all members of the Committee. COMPENSATION COMMITTEE Melvin J. Sallen, Chairman Gordon B. Baty R.

APPROVAL OF 1998 STOCK OPTION PLAN FOR NON-EMPLOYEE DIRECTORS There will be presented at the meeting a proposal to approve the Mercury Computer Systems, Inc. 1998 Stock Option Plan for Non-Employee Directors (the "1998 Non-Employee Director Plan"), which was adopted by the Corporation's Board of Directors on June 15, 1998. The 1998 Non-Employee Director Plan is intended to attract and retain the services of experienced and knowledgeable independent Directors who are not employees of the Corporation through continuing ownership of the Corporation's Common Stock. Under regulations of the Nasdaq Stock Market, any plan providing for the grant of options to purchase more than 25,000 shares, any of which may be granted to a Director, is to be approved by the Stockholders. The Board of Directors recommends that the Stockholders approve the 1998 Non-Employee Director Plan. The affirmative vote of the holders of at least a majority of a quorum of the Corporation's Common Stock voting in person or by proxy at the meeting will be required for such approval. Set forth below is a summary of the principal provisions of the 1998 Non-Employee Director Plan. A copy of the entire plan is available from the Clerk of the Corporation upon request. Terms and Provisions of Options. The 1998 Non-Employee Director Plan provides for the grant of non-qualified options not intended to meet the requirements of Section 422 of the Internal Revenue Code for the purchase of the Corporation's Common Stock by each of the current non-employee Directors of the Corporation and by each other person who is duly elected as a non-employee Director of the Corporation subject to availability of shares under the 1998 Non-Employee Director Plan. The maximum number of shares for which options may be granted under the 1998 Non-Employee Director Plan is 50,000 shares, subject to adjustment for capital changes. Under the 1998 Non-Employee Director Plan, the Corporation will grant to each non-employee Director on September 30th of each year options to purchase that number of shares of Common Stock equal to 1% of the net income of the Corporation for the most recent fiscal year ending prior to the date of grant divided by the fair market value of a share of the Corporation's Common Stock on the first day of such fiscal year, divided by the number of non- employee Directors in office at the time of grant. Options granted under the 1998 Non-Employee Director Plan will vest equally over three years from the date of grant, with an exercise price equal to the per share fair market value of the Corporation's Common Stock on 12 16 the date of grant of the option. The closing price of the Corporation's Common Stock on the Nasdaq National Market was $13.00 on September 14, 1998. Options granted under the 1998 Non-Employee Director Plan generally are not assignable or transferable by the optionee other than by will or by the laws of descent and distribution or pursuant to a qualified domestic relations order. The exercise price of options granted under the 1998 Non-Employee Director Plan must be paid in full, in cash or by certified check, upon exercise; provided, however, that there shall be no such exercise at any one time as to fewer than the lesser of (i) 250 shares, or (ii) all of the remaining shares then purchasable by the person exercising the option. If the optionee ceases to be a Director of the Corporation, the option granted to such optionee may only be exercised by the optionee within one month after the date the optionee ceases to be a Director of the Corporation, unless termination as a Director was (a) by the Corporation for cause, in which case the option terminates immediately, (b) due to the optionee becoming permanently disabled, or (c) due to the death of the optionee. If the optionee ceases being a director as a result of permanent disability, then any options vested as of the date such optionee ceases being a director may be exercised by the optionee at any time within the following twelve months. In the event of the death of an optionee, any option vested as of the date of death may be exercised by the optionee's estate (or by any person who acquired the right to exercise such option by reason of the death of the optionee) at any time within twelve months of the optionee's death. The number of shares issuable under the 1998 Non-Employee Director Plan shall be adjusted to prevent dilution in the event of any reorganization, merger, consolidation, recapitalization, reclassification, stock split, combination of shares or stock dividend. The 1998 Non-Employee Director Plan will terminate ten years from the date on which it is approved by the stockholders, but the Board of Directors may at any time terminate, modify or amend the plan as it deems advisable. Following approval of the 1998 Non-Employee Director Plan by the stockholders, no further options will be granted under the Corporation's 1993 Stock Option Plan for Non-Employee Directors. TAX EFFECTS OF PLAN PARTICIPATION Options granted under the 1998 Director Plan are intended to be non-qualified stock options. No income is recognized by the optionee on the grant of a non-qualified stock option. On the exercise by an optionee of a non-qualified option, generally the excess of the fair market value of the stock when the option is exercised over its cost to the optionee will be (a) taxable to the optionee as ordinary income and (b) generally deductible for income tax purposes by the Corporation. The Internal Revenue Service will treat the exercise of a non-qualified stock option with already owned stock of the Corporation of the same type (i.e., common or preferred but not "Nonqualified Preferred" stock as defined in Section 351(g)(2) of the Code) as two transactions. First, there will be a tax-free exchange of the old shares for a like amount of new shares under Section 1036 of the Code, with the new shares retaining the basis and holding periods of the old shares. Second, the issuance of additional new shares (representing the spread between the fair market value of all the new shares and the option price) is taxable to the employee as ordinary income under Section 83 of the Code, as is the case with any non-qualified option. The new shares will have a basis equal to the spread between the fair market value of the new shares and the option price. The optionee's tax basis in his stock will equal his cost for the stock plus the amount of ordinary income he had to recognize with respect to the non-qualified stock option. Accordingly, upon a subsequent disposition of stock acquired upon the exercise of a non-qualified option, the optionee will recognize short-term or long- 13 17 term capital gain or loss, depending upon the holding period of the stock equal to the difference between the amount realized upon disposition of the stock by the optionee and his basis in the stock. OTHER MATTERS Notice of Amendment to Corporation By-Laws Pursuant to sec.17 of the Massachusetts General Corporation Law, Chapter 156B. On April 9, 1998, the Board of Directors unanimously voted to amend the By-Laws of the Company by making the following self-explanatory additions: 1. By adding the following language after the second sentence of the first paragraph of Section 3.5: Both abstentions and broker non-votes are to be counted as present for the purpose of determining the existence of a quorum for the transaction of business at any meeting. 2. By adding the following language after the last sentence of the second paragraph of Section 3.5: For purposes of determining the number of shares voting on a particular proposal, abstentions and broker non-votes are not to be counted as votes cast or shares voting. 3. By adding the following language after the last sentence of the second paragraph of Section 3.7: Both abstentions and broker non-votes are to be counted as present for the purpose of determining the existence of a quorum for the transaction of business at any meeting. However, for purposes of determining the number of shares voting on a particular proposal, abstentions and broker non-votes are not to be counted as votes cast or shares voting. Independent Public Accountants. The Board of Directors has appointed PriceWaterhouseCoopers LLP as independent auditors to examine the consolidated financial statements of the Corporation and its subsidiaries for the fiscal year ended June 30, 1999. A representative of PriceWaterhouseCoopers LLP is expected to be present at the Meeting and will have the opportunity to make a statement if he or she so desires and to respond to appropriate questions. The engagement of PriceWaterhouseCoopers LLP was approved by the Board of Directors at the recommendation of the Audit Committee of the Board of Directors. Section 16(a) Beneficial Ownership Reporting Compliance. Section 16(a) of the Securities Exchange Act of 1934 requires the Corporation's officers and Directors and persons beneficially owning more than 10% of the outstanding Common Stock of the Corporation to file reports of beneficial ownership and changes in beneficial ownership with the Securities and Exchange Commission ("SEC"). Officers, Directors, and greater than 10% beneficial owners of Common Stock are required by SEC regulation to furnish the Corporation with copies of all Section 16(a) forms they file. Based solely on copies of such forms furnished as provided above, or written representations that no Forms 5 were required, the Corporation believes that during the fiscal year ended June 30, 1998, all Section 16(a) filing requirements applicable to its officers, Directors, and beneficial owners of greater than 10% of its Common Stock were complied with, except: Mr. Melvin Sallen, a Director of the Corporation, filed one late report relating to a transaction in which a trust, of which Mr. Sallen was co-trustee and a beneficiary, purchased shares of the Corporation. Deadlines for Submission of Stockholder Proposals. Under regulations adopted by the Securities and Exchange Commission, any proposal submitted for inclusion in the Corporation's Proxy Statement relating to the Annual Meeting of Stockholders to be held in 1999 must be received at the Corporation's principal executive offices in Chelmsford, Massachusetts on or before May 14, 1999. Receipt by the Corporation of any 14 18 such proposal from a qualified stockholder in a timely manner will not ensure its inclusion in the proxy material because there are other requirements in the proxy rules for such inclusion. Stockholders interested in submitting such a proposal are advised to contact knowledgeable counsel with regards to the detailed requirements of such securities rules. In addition to the Securities and Exchange Commission requirements regarding stockholder proposals, the Corporation's By-Laws contain provisions regarding matters to be brought before stockholder meetings. If stockholder proposals, including proposals regarding the election of Director, are to be considered at the 1999 Annual Meeting of Stockholders, notice of them whether or not they are included in the Corporation's proxy statement and form of proxy, must be given by personal delivery or by United States mail, postage prepaid, to the Clerk of the Corporation on or before August 7, 1999. Other Matters. Management knows of no matters which may properly be and are likely to be brought before the meeting other than the matters discussed herein. However, if any other matters properly come before the meeting, the persons named in the enclosed proxy will vote in accordance with their best judgment. The cost of this solicitation will be born by the Corporation. It is expected that the solicitation will be made primarily by mail, but regular employees or representatives of the Corporation (none of whom will receive any extra compensation for their activities) may also solicit proxies by telephone, telegraph and in person and arrange for brokerage houses and other custodians, nominees and fiduciaries to send proxies and proxy material to their principals at the expense of the Corporation. 10-K REPORT. THE CORPORATION WILL PROVIDE EACH BENEFICIAL OWNER OF ITS SECURITIES WITH A COPY OF AN ANNUAL REPORT ON FORM 10-K, INCLUDING THE FINANCIAL STATEMENTS AND SCHEDULES THERETO, REQUIRED TO BE FILED WITH THE SECURITIES AND EXCHANGE COMMISSION FOR THE CORPORATION'S MOST RECENT FISCAL YEAR, WITHOUT CHARGE, UPON RECEIPT OF A WRITTEN REQUEST FROM SUCH PERSON. SUCH REQUEST SHOULD BE SENT TO MR. G. MEAD WYMAN, CHIEF FINANCIAL OFFICER, MERCURY COMPUTER SYSTEMS, INC., 199 RIVERNECK ROAD, CHELMSFORD, MASSACHUSETTS 01824. VOTING PROXIES The Board of Directors recommends an affirmative vote on all proposals specified. Proxies will be voted as specified.
