VICOR CORPORATION 25 FRONTAGE ROAD ANDOVER, MASSACHUSETTS 01810 TELEPHONE (978) 470-2900 ------------------------ PROXY STATEMENT --------------------- FOR THE 2003 ANNUAL MEETING OF STOCKHOLDERS TO BE HELD ON THURSDAY, JUNE 26, 2003 April 29, 2003 This Proxy Statement is furnished in connection with the solicitation of proxies by the Board of Directors of Vicor Corporation (the "Corporation") from holders of the outstanding shares of capital stock of the Corporation for use at the 2003 Annual Meeting of Stockholders (the "Annual Meeting") of the Corporation to be held on Thursday, June 26, 2003 at 5:00 p.m., local time, at the Andover Country Club, 60 Canterbury Street, Andover, Massachusetts, and at any adjournments or postponements thereof. At the Annual Meeting, stockholders will be asked to consider and vote on the proposals set forth in this Proxy Statement. This Proxy Statement and the accompanying Notice of Annual Meeting and Proxy Card are first being sent to stockholders on or about May 16, 2003. The Board of Directors has fixed the close of business on April 30, 2003 as the record date for the determination of stockholders entitled to receive notice of and to vote at the Annual Meeting (the "Record Date"). Only stockholders of record at the close of business on the Record Date will be entitled to receive notice of and to vote at the Annual Meeting. As of March 31, 2003, there were outstanding and entitled to vote 29,879,680 shares of Common Stock and 11,880,100 shares of Class B Common Stock of the Corporation. Each share of Common Stock entitles the holder thereof to one vote per share and each share of Class B Common Stock entitles the holder thereof to ten (10) votes per share. Shares of Common Stock and Class B Common Stock will vote together as a single class on the proposals set forth in this Proxy Statement. Stockholders of the Corporation are requested to complete, date, sign and return the accompanying Proxy Card in the enclosed postage-prepaid envelope. Shares represented by a properly executed proxy received prior to the vote at the Annual Meeting and not revoked will be voted at the Annual Meeting as directed on the proxy. If a properly executed proxy is submitted and no instructions are given, the proxy will be voted FOR the fixing of the Board of Directors at seven and the election of the seven nominees for Directors of the Corporation named in this Proxy Statement. It is not anticipated that any matters other than those set forth in this Proxy Statement will be presented at the Annual Meeting. If other matters are presented, proxies will be voted in accordance with the discretion of the proxy holders. A stockholder of record may revoke a proxy at any time before it has been exercised by (1) filing a written revocation with the Secretary of the Corporation at the address of the Corporation set forth above; (2) filing a duly executed proxy bearing a later date; or (3) appearing in person, notifying the Secretary and voting by ballot at the Annual Meeting. Any stockholder of record as of the Record Date attending the Annual Meeting may vote in person whether or not a proxy has been previously given, but the presence (without further action) of a stockholder at the Annual Meeting will not constitute revocation of a previously given proxy. The presence, in person or by proxy, of holders of a majority in interest of all stock issued, outstanding and entitled to vote at the Annual Meeting shall constitute a quorum for the transaction of business at the Annual Meeting. Shares that reflect abstentions or "broker non-votes" (i.e., shares held by brokers or other nominees that are represented at the Annual Meeting but as to which such brokers or nominees have not received instructions from the beneficial owners or persons entitled to vote such shares and, with respect to one or more but not all proposals, such brokers or nominees do not have discretionary voting power to vote such shares) will be counted for purposes of determining whether a quorum is present for the transaction of business at the Annual Meeting.

The cost of solicitation of proxies in the form enclosed herewith will be borne by the Corporation. In addition to the solicitation of proxies by mail, the Directors, officers and employees of the Corporation may also solicit proxies personally or by telephone without special compensation for such activities. The Corporation will also request persons, firms and corporations holding shares in their names or in the names of their nominees, which are beneficially owned by others, to send proxy materials to and obtain proxies from such beneficial owners. The Corporation will reimburse such holders for their reasonable expenses in connection therewith. The Corporation's 2002 Annual Report (the "Annual Report"), including financial statements for the fiscal year ended December 31, 2002, is being mailed to stockholders concurrently with this Proxy Statement. The Annual Report, however, is not part of the proxy solicitation materials. PROPOSAL 1 ELECTION OF DIRECTORS The Board of Directors of the Corporation has nominated the seven individuals named below for election as Directors. Each of the nominees is presently serving as a Director of the Corporation. If elected, the nominees will serve until the 2004 Annual Meeting of Stockholders and until their respective successors are duly elected and qualified. Properly executed proxies will be voted for the nominees named below unless otherwise specified in the proxy. The Board of Directors anticipates that each of the nominees, if elected, will serve as a Director. However, if any person nominated by the Board of Directors fails to stand for election or is unable to accept election, proxies solicited hereby will be voted either for the election of another person designated by the Board of Directors or to fix the number of Directors at a lesser number and elect the nominees able and willing to serve. A plurality of the votes cast by the holders of Common Stock and Class B Common Stock, voting together as a single class, for a nominee for Director shall elect such nominee. Accordingly, abstentions, broker non-votes and votes withheld from any nominee will have no effect on this proposal. Holders of voting rights sufficient to elect each of the nominees named below have indicated an intention to vote in favor of such nominees. THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE FOR ALL OF THE NOMINEES. INFORMATION REGARDING NOMINEES The following sets forth certain information as of March 31, 2003 with respect to the seven nominees for election to the Board of Directors.

OPTION/SAR GRANTS IN LAST FISCAL YEAR The following table sets forth each grant of stock options during the fiscal year ended December 31, 2002 to the Chief Executive Officer and each other executive officer named in the Summary Compensation Table. All stock options granted in 2002 were options to purchase shares of the Corporation's Common Stock. No stock appreciation rights ("SARs") have been granted by the Corporation. The table also shows the value of the options at the end of the option terms assuming the price of the Corporation's Common Stock appreciates annually by 5% and 10%, respectively. The options will only have value if they are exercised, and that value will depend entirely on the market price of the Common Stock on the exercise date. Potential realizable values are based on assumed compound annual appreciation rates specified by the SEC and are not intended to forecast possible future appreciation, if any, of the price of the Common Stock. There can be no assurance that the price of the Common Stock will appreciate at the rates shown in the table. A total of 1,053,377 options to purchase Common Stock were granted to the Corporation's employees during fiscal year ended December 31, 2002.

Options are in-the-money if the market value of the shares covered thereby is greater than the option exercise price. REPORT OF THE EXECUTIVE COMPENSATION COMMITTEE OF THE BOARD OF DIRECTORS The Executive Compensation Committee of the Board of Directors of the Corporation (the "Compensation Committee") consists of David T. Riddiford, Estia J. Eichten, and M. Michael Ansour, none of whom are employees of the Corporation. The Compensation Committee establishes the terms of and grants awards under the Corporation's 1993 Stock Option Plan (the "1993 Plan"), the 1998 Stock Option and Incentive Plan (the "1998" Plan), the 2000 Plan and other benefit plans. The Compensation Committee also approves compensation policies for executive officers. Compensation Policies for Executive Officers The Corporation's compensation program for executive officers currently consists primarily of a base salary and awards of stock options. In addition to base salary, the Corporation provides certain benefits to executive officers, such as automobile allowances and enhanced health insurance coverage, that are not available to employees generally. Salary levels for executive officers are proposed by management and approved by the Compensation Committee. There were no base salary increases in 2002 for any executive officer due to the continued slowdown in the Corporation's business. The primary element of the Corporation's incentive compensation program has been the granting of options to purchase shares of the Corporation's Common Stock under the Corporation's 1993 Plan, 1998 Plan and 2000 Plan. Substantially all of the Corporation's employees, including its executive officers, participate in the 1993 Plan, the 1998 Plan and the 2000 Plan. The 1993 Plan, the 1998 Plan and the 2000 Plan are designed to give each participating employee an ownership interest in the Corporation and to align the interests of the employees with those of the Corporation's stockholders. Stock options are granted to employees and executive officers based upon guidelines established by the Board of Directors and the Compensation Committee. From time to time, the Corporation grants continuation option awards ("Continuation Awards") to employees and executive officers. The number of continuation option awards granted to executive officers is based on a formula that calculates the quotient obtained by dividing (A) the product of two times the executive officer's merit salary increase (based on the executive officer's performance review) by (B) the market value per share of the Corporation's Common Stock on the date of grant. The number of options to be granted is approved by the Compensation Committee and is not based on any corporate or business unit performance measures. All Continuation Awards are made with a five-year vesting schedule. Because there were no base salary increases in 2002, there were no continuation option awards granted in 2002 to employees or executives of the Corporation. 8

In addition to Continuation Awards, the Corporation began a Quarterly Profit Option Plan (the "QPOP") in 2000. Options under the QPOP are granted to all eligible employees and officers. Under the QPOP, the aggregate number of options available for grant each quarter with respect to each of the Corporation's business units is based on a formula, which calculates the quotient obtained by dividing (A) the sum of (1) 50% of the applicable business unit's net income for the applicable quarter plus (2) two times the increase in net income (if any) between the applicable quarter and the corresponding quarter of the prior year, by (B) the market value per share of the Corporation's Common Stock on the date of grant. Option grants under the QPOP are based upon an employee's salary and length of service. For eligible employees and officers, their portion of the QPOP option award is determined by calculating their pro-rata share of the employee salary pool. The employee salary pool is the sum of each employee's base salary multiplied by a percentage which is based on such employee's length of service with the Corporation. For eligible employees and officers having less than five years of service, a rate of 40% of base salary is used. The rate increases to 50% at five years of service and then increases an additional 2% for each year of service up to a maximum of 70% at 15 years of service. Forty percent (40%) of the options become exercisable seven months after the date of grant, with the remainder vesting in three equal annual installments of 20% thereafter. Each quarter, 15% of the options available under the QPOP are reserved for Outstanding Contributor awards for eligible employees and officers. These awards are intended to recognize and reward employees or teams of employees for contributions beyond expected job performance. Nominations are submitted by department managers and supervisors, which are reviewed and approved by a review committee designated by the Corporation's officers. These options become exercisable in five equal annual installments. All options granted under the QPOP, including the Outstanding Contributor awards, are approved by the Compensation Committee. Finally, to the extent applicable to the Corporation, the Compensation Committee intends to review and to take any necessary and appropriate steps to ensure that the Corporation complies with certain income tax regulations, which, if not satisfied, would limit the deductibility of executive compensation above specified amounts. Compensation of Chief Executive Officer The Compensation Committee approves the annual salary for Mr. Vinciarelli, the Corporation's Chief Executive Officer. The Compensation Committee does not have specific criteria, either in terms of individual or corporate performance, in evaluating the base salary of the Chief Executive Officer. In light of the relatively low cash compensation paid to the Chief Executive Officer, the Compensation Committee has not attempted to relate compensation of the Chief Executive Officer to the performance of the Corporation. Based on salary data from surveys and other sources, the Compensation Committee believes that the Chief Executive Officer's salary is at the lower end of the range of salaries for CEOs of comparable companies. In 2001, the Compensation Committee determined to begin including Mr. Vinciarelli in the granting of stock options described above as "QPOP" options, however, Mr. Vinciarelli did not receive any QPOP awards in 2002. As in prior years, the Corporation continued to exclude Mr. Vinciarelli from the granting of Continuation Awards, if any, because of Mr. Vinciarelli's significant stock holdings in the Corporation and the practice of basing such awards on performance reviews that were typically prepared by Mr. Vinciarelli. Submitted by the Executive Compensation Committee: M. Michael Ansour Estia J. Eichten David T. Riddiford COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION Messrs. Eichten, Riddiford, and Ansour serve on the Compensation Committee. Messrs. Eichten, Riddiford and Ansour do not serve as officers of the Corporation. The Corporation is not aware of any compensation committee interlocks. 9

REPORT OF THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS The Audit Committee oversees the Corporation's financial reporting process on behalf of the Board of Directors. Management has the primary responsibility for the financial statements and the reporting process including the systems of internal controls. In fulfilling its oversight responsibilities, the Audit Committee reviewed the audited financial statements in the Annual Report with management including a discussion of the quality, not just the acceptability, of the accounting principles, the reasonableness of significant judgments and the clarity of disclosures in the financial statements. The Audit Committee reviewed with the independent auditors, who are responsible for expressing an opinion on the conformity of those audited financial statements with generally accepted accounting principles, their judgments as to the quality, not just the acceptability, of the Corporation's accounting principles and such other matters as are required to be discussed with the Audit Committee under generally accepted auditing standards. In addition, the Audit Committee has discussed with the independent auditors the auditors' independence from management and the Corporation, including the matters in the written disclosures required by the Independence Standards Board, and considered the compatibility of nonaudit services with the auditors' independence. The Audit Committee discussed with the independent auditors the overall scope and plans for their audit. The Audit Committee meets with the independent auditors, with and without management present, to discuss the results of their examination, their evaluation of the Corporation's internal controls, and the overall quality of the Corporation's financial reporting. The Audit Committee held four meetings during fiscal 2002. In reliance on the reviews and discussions referred to above, the Audit Committee recommended to the Board of Directors (and the Board approved) that the audited financial statements be included in the Corporation's Annual Report on Form 10-K for the year ended December 31, 2002 for filing with the SEC. Submitted by the Audit Committee: Samuel Anderson M. Michael Ansour David T. Riddiford APPOINTMENT OF INDEPENDENT AUDITORS The Board of Directors has reappointed Ernst & Young LLP as independent auditors to audit the financial statements of the Corporation for the current fiscal year. During the year ended December 31, 2002, the Corporation paid the following fees to Ernst & Young LLP: Audit Fees $250,000 Financial Information Systems Design and Implementation Fees $ -- Audit Related Fees (1) $ 78,000 All Other Fees (2) $143,000 (1) Includes fees for accounting and SEC consultations, audits of employee benefit plans and for statutory audits of foreign subsidiaries. (2) Includes fees for domestic and international tax services. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS Mr. Vinciarelli, the President and Chief Executive Officer of the Corporation, had previously borrowed funds from the Corporation pursuant to a series of unsecured term notes. The notes had terms of eight years and matured at various dates through March 2009. Each note bore interest at the greater of the prime borrowing rate less 1%, or the applicable federal rate under the Internal Revenue Code of 1986, as amended. The largest aggregate amount of all indebtedness outstanding at any time during 2002 was $2,312,581, including accrued interest. The notes were repaid in full in December 2002. 10

STOCKHOLDER RETURN PERFORMANCE GRAPH The graph set forth below presents the cumulative, five-year stockholder return for each of the Corporation's Common Stock, the Standard & Poor's 500 Index ("S & P 500 Index") and an index of peer group companies selected by the Corporation (the "Peer Group"). The Peer Group consists of the following ten (10) publicly-traded companies in the specialty electronic component industry: Analog Devices Incorporated; Intel Corporation; Linear Technology Corporation; LSI Logic Corporation; Xilinx Incorporated; Maxim Integrated Products, Inc. ("Maxim"); Semtech Corporation; Intersil Corporation; Altera Corporation and RF Micro Devices, Inc. One company historically selected by the Corporation for inclusion in the Peer Group (i.e. Dallas Semiconductor) was acquired in 2002. The Corporation replaced Dallas Semiconductor Corporation ("DSC") in its Peer Group with Maxim, the company that acquired DSC in 2002. In addition, the Corporation removed two companies from inclusion in the Peer Group, Cypress Semiconductor Corporation and Integrated Device Technology Incorporated, as management of the Corporation believes that their product and market focus is no longer consistent with that of the Corporation. The Corporation added four new companies for inclusion in the Peer Group: Semtech Corporation, Intersil Corporation, Altera Corporation and RF Micro Devices, Inc. whose product and market focus is more in line with that of the Corporation. In accordance with the rules of the Securities and Exchange Commission, the graph also includes the data for the peer group companies used in the Corporation's proxy statement for its 2002 Annual Meeting of Stockholders ("Prior Peer Group"). The graph assumes an investment of $100 on December 31, 1997 in each of the Corporation's Common Stock, the S & P 500 Index, the Prior Peer Group and the Current Peer Group, and assumes reinvestment of all dividends. The peer group indices used in the graph are market capitalization-weighted. The historical information set forth below is not necessarily indicative of future performance.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE Section 16(a) of the Exchange Act requires the Corporation's executive officers and Directors, and persons who own more than 10% of a registered class of the Corporation's equity securities (collectively, "Insiders"), to file reports of ownership and changes in ownership with the SEC and NASDAQ. Insiders are required by SEC regulation to furnish the Corporation with copies of all Section 16(a) forms they file. To the Corporation's knowledge, based solely on a review of copies of such reports and written representations that no other reports were required during the fiscal year ended December 31, 2002, all transactions in the Corporation's securities that were engaged in by Insiders, and therefore required to be disclosed pursuant to Section 16(a) of the Exchange Act, were timely reported, except one transaction that Mr. David T. Riddiford failed to timely report. INDEPENDENT AUDITORS The Corporation has selected Ernst & Young LLP as the independent auditors for the Corporation for the fiscal year ending December 31, 2003. A representative of Ernst & Young LLP is expected to be present at the Annual Meeting and will be given the opportunity to make a statement.
