3 [LOGO] PLX TECHNOLOGY, INC. 390 POTRERO AVENUE SUNNYVALE, CALIFORNIA 94086 PROXY STATEMENT GENERAL INFORMATION This Proxy Statement is furnished to the stockholders of PLX Technology, Inc., a Delaware corporation (the "Company"), in connection with the solicitation by the Board of Directors of the Company (the "Board" or "Board of Directors") of proxies in the accompanying form for use in voting at the 2000 Annual Meeting of Stockholders of the Company (the "Annual Meeting") to be held on May 24, 2000 at the Company's headquarters, 390 Potrero Avenue, Sunnyvale, California, at 10:00 a.m., Pacific Time, and any adjournment or postponement thereof. The shares represented by proxies received, properly marked, dated, executed and not revoked will be voted at the Annual Meeting. REVOCABILITY OF PROXIES Any proxy given pursuant to this solicitation may be revoked by the person giving it at any time before it is exercised by delivering to the Company (to the attention of Scott M. Gibson, the Company's Secretary) a written notice of revocation or a duly executed proxy bearing a later date, or by attending the Annual Meeting and voting in person. SOLICITATION AND VOTING PROCEDURES This Proxy Statement and the accompanying proxy were first sent by mail to stockholders on or about April 14, 2000. The solicitation of proxies will be conducted by mail, and the Company will bear all attendant costs. These costs will include the expense of preparing and mailing proxy materials for the Annual Meeting and reimbursements paid to brokerage firms and others for their expenses incurred in forwarding solicitation material regarding the Annual Meeting to beneficial owners of the Company's Common Stock. The Company may conduct further solicitation personally, by telephone or by facsimile through its officers, directors and regular employees, none of whom will receive additional compensation for assisting with such solicitation. The close of business on March 15, 2000 has been fixed as the record date (the "Record Date") for determining the holders of shares of Common Stock of the Company entitled to notice of and to vote at the Annual Meeting. As of the close of business on the Record Date, the Company had approximately 22,034,996 shares of Common Stock outstanding and entitled to vote at the Annual Meeting. Each outstanding share of Common Stock on the Record Date is entitled to one vote on all matters. A majority of the shares entitled to vote, present in person or represented by proxy, shall constitute a quorum at the Annual Meeting. For the election of directors, the candidates receiving the greatest number of affirmative votes are elected, provided a quorum is present and voting. The affirmative vote of a majority of the outstanding shares of the Company's Common Stock present in person or represented by proxy at the Annual Meeting shall be required to approve Proposal Nos. 2 and 3 being submitted to the stockholders for their consideration. Under the General Corporation Law of the State of Delaware, an abstaining vote and a broker "non-vote" are counted as present and are, therefore, included for purposes of determining whether a quorum of shares is present at a meeting. However, broker "non-votes" are not deemed to be "votes entitled to vote." As a result, broker "non-votes" are not included in the tabulation of the voting results on the election of directors or issues requiring approval of a majority of the votes entitled to vote and, therefore, do not have the effect of votes in opposition in such tabulations. A broker "non-vote" occurs when a nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have the discretionary voting power with respect to that item and has not received instructions from the beneficial owner. Because abstentions will be included in tabulations of the votes entitled to vote for purposes of determining whether a proposal has been approved, abstentions have the same effect as negative votes. Broker non-votes and shares as to which proxy authority has been withheld with respect to any matter are not deemed to be entitled to vote for purposes of determining whether stockholder approval of a matter has been obtained and thus have no effect on the vote. 2

4 PROPOSAL NO. 1 ELECTION OF DIRECTORS As set by the Board of Directors pursuant to the Bylaws of the Company, the authorized number of directors is set at six. Six directors will be elected at the Annual Meeting to serve until the 2001 annual meeting of stockholders or until each director's successor is elected or appointed and qualified or until the earlier resignation or removal of the director. In the event that any nominee of the Company is unable or declines to serve as a director at the time of the Annual Meeting, the proxies will be voted for any nominee who shall be designated by the present Board of Directors to fill the vacancy. In the event that additional persons are nominated for election as directors, the proxy holders intend to vote all proxies received by them in such a manner as will assure the election of as many of the nominees listed below as possible, and, in such event, the specific nominees to be voted for will be determined by the proxy holders. The Board has no reason to believe that any of the persons named below will be unable or unwilling to serve as a director, if elected. Each of the six nominees for director who receives the greatest number of votes will be elected. Set forth below are the names, ages and certain biographical information relating to the director nominees. NAME OF NOMINEE AGE POSITION WITH COMPANY DIRECTOR SINCE Michael J.

The Board does not have a nominating committee or a committee performing the functions of a nominating committee. While there are no formal procedures for stockholders to recommend nominations, the Board will consider stockholder recommendations. Such recommendations should be addressed to Scott M. Gibson, the Company's Secretary at the Company's principal executive offices. COMPENSATION OF DIRECTORS Non-employee directors of the Company receive $4,000 upon initial election at the annual stockholders meeting and receive $2,000 in compensation for each Board of Directors meeting attended.

On the date of each annual stockholders' meeting, each incumbent non-employee director who has served on the Board for at least eleven months will automatically be granted an option to 4

6 purchase 5,000 shares of the Company's Common Stock.

9 PROPOSAL NO. 2 APPROVAL OF AMENDMENTS TO THE 1999 STOCK INCENTIVE PLAN The Company's stockholders are being asked to approve amendments to the Company's 1999 Stock Incentive Plan (the "1999 Plan"). The proposed amendments to the 1999 Plan will (i) increase the number of shares reserved for issuance under the 1999 Plan from 1,000,000 shares to 2,500,000 shares and (ii) limit the maximum number of options and stock appreciation rights that may be awarded to an employee in any one fiscal year of the Company in order to ensure compliance with the requirements of Section 162(m) of the Internal Revenue Code of 1986, as amended (the "Code"). The amendments to the 1999 Plan will enable the Company to grant awards as needed to attract employees and other service providers. The 1999 Plan is intended to enhance the Company's ability to provide key individuals with awards and incentives commensurate with their contributions and competitive with those offered by other employers, and to increase stockholder value by further aligning the interests of key individuals with the interests of the Company's stockholders by providing an opportunity to benefit from stock price appreciation that generally accompanies improved financial performance. The Board of Directors believes that the Company's long term success is dependent upon the ability of the Company to attract and retain highly qualified individuals who, by virtue of their ability and qualifications, make important contributions to the Company. The affirmative vote of a majority of the shares present in person or by proxy at the Annual Meeting and entitled to vote is required for adoption of Proposal No. 2. THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR APPROVAL OF THE AMENDMENTS TO THE 1999 PLAN The following summary of the 1999 Plan, including the proposed amendments, is subject in its entirety to the specific language of the 1999 Plan, a copy of which is available to any stockholder upon request. GENERAL DESCRIPTION The 1999 Plan was approved by the Board of Directors in January 1999 and by the Company's stockholders in March 1999. In March 2000, the Board of Directors approved amendments to the 1999 Plan, conditioned upon and not to take effect until approved by the Company's stockholders, (i) to increase the number of shares reserved for issuance under the 1999 Plan from 1,000,000 shares to 2,500,000 shares, and (ii) to limit the maximum number of options and stock appreciation rights that may be awarded to an employee in any one fiscal year of the Company in order to ensure compliance with the requirements of Section 162(m) of the Code. The purposes of the 1999 Plan are to give the Company's employees and others who perform substantial services to the Company an incentive, through ownership of the Company's Common Stock, to continue in service to the Company, and to help the Company compete effectively with other enterprises for the services of qualified individuals. The 1999 Plan permits the grant of "incentive stock options" ("ISOs") within the meaning of Section 422 of the Code only to employees of the Company or any parent or subsidiary corporation of the Company. Awards other than incentive stock options may be granted to employees, directors and consultants. As of March 15, 2000, options to purchase a total of 818,314 shares held by 83 optionees were outstanding as of such date at a weighted average exercise price of $20.59 per share, and 181,686 shares remained available for future grant under 1999 Plan. As of that same date, the number of employees, directors and consultants eligible to receive grants under the 1999 Plan was approximately 95 persons. The 1999 Plan provides for the grant of (i) shares, (ii) options, stock appreciation rights ("SARs") or similar rights with an exercise or conversion privilege at a fixed or variable price related to the Common Stock and/or the passage of time, the occurrence of one or more events, or the satisfaction of performance criteria or other conditions, or (iii) any other security with the value derived from the value of the Common Stock of the Company (collectively, 8

10 the "Awards"). Such Awards include, without limitation, options, SARs, sales or bonuses of restricted stock, dividend equivalent rights, performance units or performance shares. AMENDMENT TO INCREASE SHARES RESERVED. The current number of shares reserved for issuance under the 1999 Plan is 1,000,000. The proposed amendment to the 1999 Plan provides that the number of shares reserved for issuance will be increased by 1,500,000 shares to a total reserve of 2,500,000 shares. APPROVAL OF CODE SECTION 162(M) LIMITATIONS. The Board of Directors, subject to stockholder approval, adopted an amendment to the 1999 Plan to limit the maximum number of options and SARs which may be awarded to an employee in any fiscal year of the Company to 1,000,000 shares. The purpose of the amendment is to ensure that any options and SARs granted under the 1999 Plan after the Annual Meeting will qualify as "performance-based compensation" under Code Section 162(m). Under Code Section 162(m) no deduction is allowed in any taxable year of the Company for compensation in excess of $1 million paid to its chief executive officer and each of its four most highly paid other executive officers who are serving in such capacities as of the last day of such taxable year. An exception to this rule applies to compensation that is paid pursuant to a stock incentive plan approved by the Company's stockholders and that specifies, among other things, the maximum number of shares with respect to which options and SARs may be granted to eligible employees under such plan during a specified period. Compensation paid pursuant to options and SARs granted under such a plan is deemed to be inherently performance-based, since such awards provide value to employees only if the stock price appreciates. While Code Section 162(m) generally became effective in 1994, a special rule allows options granted under the 1999 Plan to be treated as qualifying under Code Section 162(m) until this Annual Meeting without having a per-person share limit. If stockholders do not approve the Code Section 162(m) amendment, any compensation expense of the Company associated with the options and SARs granted under the 1999 Plan in excess of the shares currently available for issuance (together with all other non-performance based compensation) in excess of $1 million for any of the Company's five highest paid officers will not be deductible under the Code. ADMINISTRATION. The 1999 Plan is administered, with respect to grants to directors, officers, consultants, and employees, by the Administrator of the 1999 Plan, defined as the Board or a committee designated by the Board. The committee is constituted in such a manner as to satisfy applicable laws, including Rule 16b-3 promulgated under the Securities Exchange Act of 1934, as amended ("Rule 16b-3"). With respect to Awards subject to Code Section 162(m), the committee will be comprised solely of two or more "outside directors" as defined under Code Section 162(m) and applicable tax regulations. For grants of Awards to individuals not subject to Rule 16b-3 and Code Section 162(m), the Board of Directors may authorize one or more officers to grant such Awards. AMENDMENT AND TERMINATION. The Board may at any time amend, suspend or terminate the 1999 Plan. To the extent necessary to comply with applicable provisions of federal securities laws, state corporate and securities laws, the Code, the rules of any applicable stock exchange or national market system, and the rules of any foreign jurisdiction applicable to Awards granted to residents therein, the Company will obtain stockholder approval of any amendment to the 1999 Plan in such a manner and to such a degree as required. The 1999 Plan will terminate in January 2009 unless previously terminated by the Board of Directors. OTHER TERMS. Stock options granted under the 1999 Plan may be either incentive stock options under the provisions of Section 422 of the Code, or non-qualified stock options. Incentive stock options may be granted only to employees of the Company or any parent or subsidiary corporation of the Company. Awards other than incentive stock options may be granted to employees, directors and consultants. Under the 1999 Plan, Awards may be granted to such employees, directors or consultants who are residing in foreign jurisdictions as the Administrator may determine from time to time. The 1999 Plan authorizes the Administrator to select the employees, directors and consultants of the Company to whom Awards may be granted and to determine the terms and conditions of any Award; however, the term of an incentive stock option may not be for more than 10 years (or 5 years in the case of incentive stock options granted to any grantee who owns stock representing more than 10% of the combined voting power of the Company or any parent or subsidiary corporation of the Company). The 1999 Plan authorizes the Administrator to grant Awards at an exercise price determined by the Administrator. In the case of incentive stock options, such price cannot be less than 100% (or 110%, in the case of incentive stock options granted to any grantee who owns stock representing more than 10% of the combined voting power of the Company or any parent or subsidiary corporation of the Company) of 9

11 the fair market value of the Common Stock on the date the option is granted. The exercise price of Awards intended to qualify as performance-based compensation for purposes of Code Section 162(m) shall not be less than 100% of the fair market value. The exercise price is payable in cash with such documentation as the Administrator and the broker, if applicable, shall require to effect an exercise of an Award and delivery to the Company of the sale proceeds required to pay the exercise price, or with shares of Common Stock. The aggregate fair market value of the Common Stock with respect to any incentive stock options that are exercisable for the first time by an eligible employee in any calendar year may not exceed $100,000. The Awards may be granted subject to vesting schedules and restrictions on transfer and repurchase or forfeiture rights in favor of the Company as specified in the agreements to be issued under the 1999 Plan. The Administrator has the authority to accelerate the vesting schedule of Awards so that they become fully vested, exercisable, and released from any restrictions on transfer and repurchase or forfeiture rights in the event of a Corporate Transaction, a Change in Control or a Subsidiary Disposition, each as defined in the 1999 Plan. Effective upon the consummation of the Corporate Transaction, all outstanding Awards under the 1999 Plan will terminate unless assumed by the successor company or its parent. In the event of a Change in Control or a Subsidiary Disposition, each Award shall remain exercisable until the expiration or sooner termination of the Award term. The 1999 Plan also permits the Administrator to include a provision whereby the grantee may elect at any time while an employee, director or consultant to exercise any part or all of the Award prior to full vesting of the Award. The 1999 Plan provides that incentive stock options may not be sold, pledged, assigned, hypothecated, transferred or disposed of in any manner other than by will or by the laws of descent or distribution and may be exercised during the lifetime of the grantee only by the grantee. However, the 1999 Plan permits the designation of beneficiaries by holders of incentive stock options. Other Awards are transferable to the extent provided in the Award agreement. Under the 1999 Plan, the Administrator may establish one or more programs under the 1999 Plan to permit selected grantees the opportunity to elect to defer receipt of consideration payable under an Award. The Administrator also may establish under the 1999 Plan separate programs for the grant of particular forms of Awards to one or more classes of grantees. CERTAIN FEDERAL TAX CONSEQUENCES. The grant of a non-qualified stock option under the 1999 Plan will not result in any federal income tax consequences to the optionee or to the Company. Upon exercise of a non-qualified stock option, the optionee is subject to income taxes at the rate applicable to ordinary compensation income on the difference between the option exercise price and the fair market value of the shares on the date of exercise. This income is subject to withholding for federal income and employment tax purposes. The Company is entitled to an income tax deduction in the amount of the income recognized by the optionee, subject to possible limitations imposed by Section 162(m) of the Code. Any gain or loss on the optionee's subsequent disposition of the shares of Common Stock will receive long or short-term capital gain or loss treatment, depending on whether the shares are held for more than one year following exercise. The Company does not receive a tax deduction for any such gain. The grant of an ISO under the 1999 Plan will not result in any federal income tax consequences to the optionee or to the Company. An optionee recognizes no federal taxable income upon exercising an ISO (subject to the alternative minimum tax rules discussed below), and the Company receives no deduction at the time of exercise. In the event of a disposition of stock acquired upon exercise of an ISO, the tax consequences depend upon how long the optionee has held the shares of Common Stock. If the optionee does not dispose of the shares within two years after the ISO was granted, nor within one year after the ISO was exercised, the optionee will recognize a long-term capital gain (or loss) equal to the difference between the sale price of the shares and the exercise price. The Company is not entitled to any deduction under these circumstances. If the optionee fails to satisfy either of the foregoing holding periods, he or she must recognize ordinary income in the year of the disposition (referred to as a "disqualifying disposition"). The amount of such ordinary income generally is the lesser of (i) the difference between the amount realized on the disposition and the exercise price, or (ii) the difference between the fair market value of the stock on the exercise date and the exercise price. Any gain in excess of the amount taxed as ordinary income will be treated as a long or short-term capital gain, depending on whether the stock was held for more than one year. The Company, in the year of the disqualifying disposition, is entitled to a deduction equal to the amount of ordinary income recognized by the optionee. 10

12 The "spread" under an ISO -- i.e., the difference between the fair market value of the shares at exercise and the exercise price -- is classified as an item of adjustment in the year of exercise for purposes of the alternative minimum tax. The grant of restricted stock will subject the recipient to ordinary compensation income on the difference between the amount paid for such stock and the fair market value of the shares on the date that the restrictions lapse. This income is subject to withholding for federal income and employment tax purposes. The Company is entitled to an income tax deduction in the amount of the ordinary income recognized by the recipient, subject to possible limitations imposed by Section 162(m) of the Code. Any gain or loss on the recipient's subsequent disposition of the shares will receive long or short-term capital gain or loss treatment depending on whether the shares are held for more than one year and depending on how long the stock has been held since the restrictions lapsed. The Company does not receive a tax deduction for any such gain. Recipients of restricted stock may make an election under Internal Revenue Code Section 83(b) ("Section 83(b) Election") to recognize as ordinary compensation income in the year that such restricted stock is granted the amount equal to the spread between the amount paid for such stock and the fair market value on the date of the issuance of the stock. If such an election is made, the recipient recognizes no further amounts of compensation income upon the lapse of any restrictions and any gain or loss on subsequent disposition will be long or short-term capital gain to the recipient. The Section 83(b) Election must be made within thirty days from the time the restricted stock is issued. THE FOREGOING IS ONLY A SUMMARY OF THE CURRENT EFFECT OF FEDERAL INCOME TAXATION UPON THE GRANTEE AND THE COMPANY WITH RESPECT TO THE SHARES PURCHASED UNDER THE 1999 PLAN. REFERENCE SHOULD BE MADE TO THE APPLICABLE PROVISIONS OF THE CODE. IN ADDITION, THE SUMMARY DOES NOT DISCUSS THE TAX CONSEQUENCES OF A GRANTEE'S DEATH OR THE INCOME TAX LAWS OF ANY MUNICIPALITY, STATE OR FOREIGN COUNTRY TO WHICH THE GRANTEE MAY BE SUBJECT. AMENDED PLAN BENEFITS. As of the date of this Proxy Statement, no executive officer, director and no associate of any executive office or director, has been granted any options subject to stockholder approval of the proposed amendments. The benefits to be received pursuant to the 1999 Plan amendments by the Company's executive officers, directors and employees are not determinable at this time. 11

13 PROPOSAL NO. 3 RATIFICATION OF APPOINTMENT OF INDEPENDENT AUDITORS Ernst & Young LLP has served as the Company's independent auditors since the Company's inception and has been appointed by the Board to continue as the Company's independent auditors for the Company's fiscal year ending December 31, 2000. In the event that ratification of this selection of auditors is not approved by a majority of the shares of Common Stock voting at the Annual Meeting in person or by proxy, management will review its future selection of auditors. A representative of Ernst & Young LLP is expected to be present at the Annual Meeting. The representative will have an opportunity to make a statement and to respond to appropriate questions. THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR RATIFICATION OF THE APPOINTMENT OF ERNST & YOUNG LLP AS THE COMPANY'S INDEPENDENT AUDITORS FOR THE FISCAL YEAR ENDING DECEMBER 31, 2000 REPORT OF THE COMPENSATION COMMITTEE OF THE BOARD OF DIRECTORS Notwithstanding anything to the contrary set forth in any of the Company's previous filings under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended, that might incorporate future filings, including this Proxy Statement, in whole or in part, the following report shall not be deemed to be incorporated by reference into any such filings. The Compensation Committee of the Board was formed in July 1990 and consists of D. James Guzy and Eugene Flath. Decisions concerning the compensation of the Company's executive officers are made by the Compensation Committee and reviewed by the full Board (excluding any interested director). EXECUTIVE OFFICER COMPENSATION PROGRAMS The objectives of the executive officer compensation program are to attract, retain, motivate and reward key personnel who possess the necessary leadership and management skills, through competitive base salary, annual cash bonus incentives, long-term incentive compensation in the form of stock options, and various benefits, including medical and life insurance plans. The executive compensation policies of the Compensation Committee are intended to combine competitive levels of compensation and rewards for above average performance and to align relative compensation with the achievements of key business objectives, optimal satisfaction of customers, and maximization of stockholder value. The Compensation Committee believes that stock ownership by management is beneficial in aligning management and stockholder interests, thereby enhancing stockholder value. Base Salaries. Salaries for the Company's executive officers are determined primarily on the basis of the executive officer's responsibility, general salary practices of peer companies and the officer's individual qualifications and experience. The base salaries are reviewed annually and may be adjusted by the Compensation Committee in accordance with certain criteria which include individual performance, the functions performed by the executive officer, the scope of the executive officer's on-going duties, general changes in the compensation peer group in which the Company competes for executive talent, and the Company's financial performance generally. The weight given each such factor by the Compensation Committee may vary from individual to individual. 12

14 Incentive Bonuses. The Compensation Committee believes that a cash incentive bonus plan can serve to motivate the Company's executive officers and management to address annual performance goals, using more immediate measures for performance than those reflected in the appreciation in value of stock options. The bonus amounts are based upon recommendations by management and a subjective consideration of factors including such officer's level of responsibility, individual performance, contributions to the Company's success and the Company's financial performance generally. Stock Option Grants. Stock options may be granted to executive officers and other employees under the 1999 Plan. Because of the direct relationship between the value of an option and the stock price, the Compensation Committee believes that options motivate executive officers to manage the Company in a manner that is consistent with stockholder interests. Stock option grants are intended to focus the attention of the recipient on the Company's long-term performance which the Company believes results in improved stockholder value, and to retain the services of the executive officers in a competitive job market by providing significant long-term earnings potential. To this end, stock options generally vest and become fully exercisable over a four-year period. The principal factors considered in granting stock options to executive officers of the Company are prior performance, level of responsibility, other compensation and the executive officer's ability to influence the Company's long-term growth and profitability. However, the 1999 Plan does not provide any quantitative method for weighting these factors, and a decision to grant an award is primarily based upon a subjective evaluation of the past as well as future anticipated performance. Other Compensation Plans. The Company has adopted certain general employee benefit plans in which executive officers are permitted to participate on parity with other employees. The Company also provides a 401(k) deferred compensation plan. Benefits under these general plans are indirectly tied to the Company's performance. Deductibility of Compensation. The Company is required to disclose its policy regarding qualifying executive compensation for deductibility under Section 162(m) of the Code, which provides that, for purposes of the regular income tax and the alternative minimum tax, the otherwise allowable deduction for compensation paid or accrued with respect to a covered employee of a publicly held corporation is limited to no more than $1 million per year. For the fiscal year ended December 31, 1999, no executive officer of the Company received $1 million in total compensation, nor does the Company anticipate that compensation payable to any executive officer will exceed $l million for fiscal year 2000. CHIEF EXECUTIVE OFFICER COMPENSATION The compensation of the President is reviewed annually on the same basis as discussed above for all executive officers. Mr. Salameh's base salary for the fiscal year ended December 31, 1999 was $170,000. Mr. Salameh's base salary was established in part by comparing the base salaries of chief executive officers at other companies of similar size. Mr. Salameh's base salary was at the approximate median of the base salary range for Presidents/Chief Executive Officers of comparative companies. Mr. Salameh received 163,000 stock options and a $175,744 bonus for the fiscal year ended December 31, 1999. MEMBERS OF THE COMPENSATION COMMITTEE D. James Guzy Eugene Flath 13

16 OPTION GRANTS IN LAST FISCAL YEAR The following table provides certain information with respect to stock options granted to the Named Executive Officers during the fiscal year ended December 31, 1999. In addition, as required by the Securities and Exchange Commission rules, the table sets forth the potential realizable value over the term of the option (the period from the grant to the expiration date) based on assumed rates of stock appreciation of 5% and 10%, compounded annually. These amounts are based on certain assumed rates of appreciation and do not represent the Company's estimate of future stock price. Actual gains, if any, on stock option exercises will be dependent on the future performance of the Common Stock.

CERTAIN TRANSACTIONS WITH MANAGEMENT The Company and Intel Corporation are related parties due to the fact that the chairman of the Company's Board of Directors, D. James Guzy also serves on the Board of Directors of Intel Corporation. For the years ended December 31, 1999, 1998, and 1997, net revenues, which were transacted at arm's length prices, with Intel Corporation were approximately $896,000, $330,000 and $765,000 respectively. In November 1999, the Company purchased 33,048,731 shares of preferred stock of Sebring Systems for $1,000,000. The Company expensed approximately $340,000 in 1999 due to Sebring Systems spending this amount on research and development. This amount is included below income before loss from investee in the Company's 1999 consolidated statement of operations. The Chairman of the Company's Board of Directors, D. James Guzy, also serves on the Board of Directors of Sebring Systems.

25 Options) is 2,500,000 Shares. The Shares to be issued pursuant to Awards may be authorized, but unissued, or reacquired Common Stock. (b) Any Shares covered by an Award (or portion of an Award) which is forfeited or canceled, expires or is settled in cash, shall be deemed not to have been issued for purposes of determining the maximum aggregate number of Shares which may be issued under the Plan. If any unissued Shares are retained by the Company upon exercise of an Award in order to satisfy the exercise price for such Award or any withholding taxes due with respect to such Award, such retained Shares subject to such Award shall become available for future issuance under the Plan (unless the Plan has terminated). Shares that actually have been issued under the Plan pursuant to an Award shall not be returned to the Plan and shall not become available for future issuance under the Plan, except that if unvested Shares are forfeited, or repurchased by the Company at their original purchase price, such Shares shall become available for future grant under the Plan. 4. Administration of the Plan. (a) Plan Administrator. (i) Administration with Respect to Directors and Officers. With respect to grants of Awards to Directors or Employees who are also Officers or Directors of the Company, the Plan shall be administered by (A) the Board or (B) a Committee designated by the Board, which Committee shall be constituted in such a manner as to satisfy the Applicable Laws and to permit such grants and related transactions under the Plan to be exempt from Section 16(b) of the Exchange Act in accordance with Rule 16b-3. Once appointed, such Committee shall continue to serve in its designated capacity until otherwise directed by the Board. (ii) Administration With Respect to Consultants and Other Employees. With respect to grants of Awards to Employees or Consultants who are neither Directors nor Officers of the Company, the Plan shall be administered by (A) the Board or (B) a Committee designated by the Board, which Committee shall be constituted in such a manner as to satisfy the Applicable Laws. Once appointed, such Committee shall continue to serve in its designated capacity until otherwise directed by the Board. The Board may authorize one or more Officers to grant such Awards and may limit such authority as the Board determines from time to time. (iii) Administration With Respect to Covered Employees. Notwithstanding the foregoing, grants of Awards to any Covered Employee intended to qualify as Performance-Based Compensation shall be made only by a Committee (or subcommittee of a Committee) which is comprised solely of two or more Directors eligible to serve on a committee making Awards qualifying as Performance-Based Compensation. In the case of such Awards granted to Covered Employees, references to the "Administrator" or to a "Committee" shall be deemed to be references to such Committee or subcommittee. (iv) Administration Errors. In the event an Award is granted in a manner inconsistent with the provisions of this subsection (a), such Award shall be presumptively valid as of its grant date to the extent permitted by the Applicable Laws. 6

26 (b) Powers of the Administrator. Subject to Applicable Laws and the provisions of the Plan (including any other powers given to the Administrator hereunder), and except as otherwise provided by the Board, the Administrator shall have the authority, in its discretion: (i) to select the Employees, Directors and Consultants to whom Awards may be granted from time to time hereunder; (ii) to determine whether and to what extent Awards are granted hereunder; (iii) to determine the number of Shares or the amount of other consideration to be covered by each Award granted hereunder; (iv) to approve forms of Award Agreements for use under the Plan; (v) to determine the terms and conditions of any Award granted hereunder; (vi) to amend the terms of any outstanding Award granted under the Plan, provided that any amendment that would adversely affect the Grantee's rights under an outstanding Award shall not be made without the Grantee's written consent; (vii) to construe and interpret the terms of the Plan and Awards granted pursuant to the Plan, including without limitation, any notice of Award or Award Agreement, granted pursuant to the Plan; (viii) to establish additional terms, conditions, rules or procedures to accommodate the rules or laws of applicable foreign jurisdictions and to afford Grantees favorable treatment under such laws; provided, however, that no Award shall be granted under any such additional terms, conditions, rules or procedures with terms or conditions which are inconsistent with the provisions of the Plan; and (ix) to take such other action, not inconsistent with the terms of the Plan, as the Administrator deems appropriate. (c) Effect of Administrator's Decision. All decisions, determinations and interpretations of the Administrator shall be conclusive and binding on all persons. 5. Eligibility. Awards other than Incentive Stock Options may be granted to Employees, Directors and Consultants. Incentive Stock Options may be granted only to Employees of the Company, a Parent or a Subsidiary. An Employee, Director or Consultant who has been granted an Award may, if otherwise eligible, be granted additional Awards. Awards may be granted to such Employees, Directors or Consultants who are residing in foreign jurisdictions as the Administrator may determine from time to time. 6. Terms and Conditions of Awards. 7

27 (a) Type of Awards. The Administrator is authorized under the Plan to award any type of arrangement to an Employee, Director or Consultant that is not inconsistent with the provisions of the Plan and that by its terms involves or might involve the issuance of (i) Shares, (ii) an Option, a SAR or similar right with a fixed or variable price related to the Fair Market Value of the Shares and with an exercise or conversion privilege related to the passage of time, the occurrence of one or more events, or the satisfaction of performance criteria or other conditions, or (iii) any other security with the value derived from the value of the Shares. Such awards include, without limitation, Options, SARs, sales or bonuses of Restricted Stock, Dividend Equivalent Rights, Performance Units or Performance Shares, and an Award may consist of one such security or benefit, or two (2) or more of them in any combination or alternative. (b) Designation of Award. Each Award shall be designated in the Award Agreement. In the case of an Option, the Option shall be designated as either an Incentive Stock Option or a Non-Qualified Stock Option. However, notwithstanding such designation, to the extent that the aggregate Fair Market Value of Shares subject to Options designated as Incentive Stock Options which become exercisable for the first time by a Grantee during any calendar year (under all plans of the Company or any Parent or Subsidiary) exceeds $100,000, such excess Options, to the extent of the Shares covered thereby in excess of the foregoing limitation, shall be treated as Non-Qualified Stock Options. For this purpose, Incentive Stock Options shall be taken into account in the order in which they were granted, and the Fair Market Value of the Shares shall be determined as of the date the Option with respect to such Shares is granted. (c) Conditions of Award. Subject to the terms of the Plan, the Administrator shall determine the provisions, terms, and conditions of each Award including, but not limited to, the Award vesting schedule, repurchase provisions, rights of first refusal, forfeiture provisions, form of payment (cash, Shares, or other consideration) upon settlement of the Award, payment contingencies, and satisfaction of any performance criteria. The performance criteria established by the Administrator may be based on any one of, or combination of, increase in share price, earnings per share, total stockholder return, return on equity, return on assets, return on investment, net operating income, cash flow, revenue, economic value added, personal management objectives, or other measure of performance selected by the Administrator. Partial achievement of the specified criteria may result in a payment or vesting corresponding to the degree of achievement as specified in the Award Agreement. (d) Acquisitions and Other Transactions. The Administrator may issue Awards under the Plan in settlement, assumption or substitution for, outstanding awards or obligations to grant future awards in connection with the Company or a Related Entity acquiring another entity, an interest in another entity or an additional interest in a Related Entity whether by merger, stock purchase, asset purchase or other form of transaction. (e) Deferral of Award Payment. The Administrator may establish one or more programs under the Plan to permit selected Grantees the opportunity to elect to defer receipt of consideration upon exercise of an Award, satisfaction of performance criteria, or other event that absent the election would entitle the Grantee to payment or receipt of Shares or other consideration under an Award. The Administrator may establish the election procedures, the 8

28 timing of such elections, the mechanisms for payments of, and accrual of interest or other earnings, if any, on amounts, Shares or other consideration so deferred, and such other terms, conditions, rules and procedures that the Administrator deems advisable for the administration of any such deferral program. (f) Award Exchange Programs. The Administrator may establish one or more programs under the Plan to permit selected Grantees to exchange an Award under the Plan for one or more other types of Awards under the Plan on such terms and conditions as determined by the Administrator from time to time. (g) Separate Programs. The Administrator may establish one or more separate programs under the Plan for the purpose of issuing particular forms of Awards to one or more classes of Grantees on such terms and conditions as determined by the Administrator from time to time. (h) Individual Option and SAR Limit. The maximum number of Shares with respect to which Options and SARs may be granted to any Grantee in any fiscal year of the Company shall be one million (1,000,000) Shares. The foregoing limitation shall be adjusted proportionately in connection with any change in the Company's capitalization pursuant to Section 10, below. To the extent required by Section 162(m) of the Code or the regulations thereunder, in applying the foregoing limitation with respect to a Grantee, if any Option or SAR is canceled, the canceled Option or SAR shall continue to count against the maximum number of Shares with respect to which Options and SARs may be granted to the Grantee. For this purpose, the repricing of an Option (or in the case of a SAR, the base amount on which the stock appreciation is calculated is reduced to reflect a reduction in the Fair Market Value of the Common Stock) shall be treated as the cancellation of the existing Option or SAR and the grant of a new Option or SAR. (i) Early Exercise. The Award Agreement may, but need not, include a provision whereby the Grantee may elect at any time while an Employee, Director or Consultant to exercise any part or all of the Award prior to full vesting of the Award. Any unvested Shares received pursuant to such exercise may be subject to a repurchase right in favor of the Company or a Related Entity or to any other restriction the Administrator determines to be appropriate. (j) Term of Award. The term of each Award shall be the term stated in the Award Agreement, provided, however, that the term of an Incentive Stock Option shall be no more than ten (10) years from the date of grant thereof. However, in the case of an Incentive Stock Option granted to a Grantee who, at the time the Option is granted, owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the term of the Incentive Stock Option shall be five (5) years from the date of grant thereof or such shorter term as may be provided in the Award Agreement. (k) Transferability of Awards. Incentive Stock Options may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent or distribution and may be exercised, during the lifetime of the Grantee, 9

29 only by the Grantee; provided, however, that the Grantee may designate a beneficiary of the Grantee's Incentive Stock Option in the event of the Grantee's death on a beneficiary designation form provided by the Administrator. Other Awards shall be transferable to the extent provided in the Award Agreement. (l) Time of Granting Awards. The date of grant of an Award shall for all purposes be the date on which the Administrator makes the determination to grant such Award, or such other date as is determined by the Administrator. Notice of the grant determination shall be given to each Employee, Director or Consultant to whom an Award is so granted within a reasonable time after the date of such grant. 7. Award Exercise or Purchase Price, Consideration, Taxes and Reload Options. (a) Exercise or Purchase Price. The exercise or purchase price, if any, for an Award shall be as follows: (i) In the case of an Incentive Stock Option: (A) granted to an Employee who, at the time of the grant of such Incentive Stock Option owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the per Share exercise price shall be not less than one hundred ten percent (110%) of the Fair Market Value per Share on the date of grant; or (B) granted to any Employee other than an Employee described in the preceding paragraph, the per Share exercise price shall be not less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. (ii) In the case of a Non-Qualified Stock Option, the per Share exercise price shall be not less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant unless otherwise determined by the Administrator. (iii) In the case of Awards intended to qualify as Performance-Based Compensation, the exercise or purchase price, if any, shall be not less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. (iv) In the case of other Awards, such price as is determined by the Administrator. (v) Notwithstanding the foregoing provisions of this Section 7(a), in the case of an Award issued pursuant to Section 6(d), above, the exercise or purchase price for the Award shall be determined in accordance with the principles of Section 424(a) of the Code. (b) Consideration. Subject to Applicable Laws, the consideration to be paid for the Shares to be issued upon exercise or purchase of an Award including the method of payment, shall be determined by the Administrator (and, in the case of an Incentive Stock Option, shall be determined at the time of grant). In addition to any other types of consideration 10

30 the Administrator may determine, the Administrator is authorized to accept as consideration for Shares issued under the Plan the following, provided that the portion of the consideration equal to the par value of the Shares must be paid in cash or other legal consideration permitted by the Delaware General Corporation Law: (i) cash; (ii) check; (iii) delivery of Grantee's promissory note with such recourse, interest, security, and redemption provisions as the Administrator determines as appropriate; (iv) surrender of Shares or delivery of a properly executed form of attestation of ownership of Shares as the Administrator may require (including withholding of Shares otherwise deliverable upon exercise of the Award) which have a Fair Market Value on the date of surrender or attestation equal to the aggregate exercise price of the Shares as to which said Award shall be exercised (but only to the extent that such exercise of the Award would not result in an accounting compensation charge with respect to the Shares used to pay the exercise price unless otherwise determined by the Administrator); (v) with respect to Options, payment through a broker-dealer sale and remittance procedure pursuant to which the Grantee (A) shall provide written instructions to a Company designated brokerage firm to effect the immediate sale of some or all of the purchased Shares and remit to the Company, out of the sale proceeds available on the settlement date, sufficient funds to cover the aggregate exercise price payable for the purchased Shares and (B) shall provide written directives to the Company to deliver the certificates for the purchased Shares directly to such brokerage firm in order to complete the sale transaction; or (vi) any combination of the foregoing methods of payment. (c) Taxes. No Shares shall be delivered under the Plan to any Grantee or other person until such Grantee or other person has made arrangements acceptable to the Administrator for the satisfaction of any foreign, federal, state, or local income and employment tax withholding obligations, including, without limitation, obligations incident to the receipt of Shares or the disqualifying disposition of Shares received on exercise of an Incentive Stock Option. Upon exercise of an Award, the Company shall withhold or collect from Grantee an amount sufficient to satisfy such tax obligations. (d) Reload Options. In the event the exercise price or tax withholding of an Option is satisfied by the Company or the Grantee's employer withholding Shares otherwise deliverable to the Grantee, the Administrator may issue the Grantee an additional Option, with terms identical to the Award Agreement under which the Option was exercised, but at an exercise price as determined by the Administrator in accordance with the Plan. 11

31 8. Exercise of Award. (a) Procedure for Exercise; Rights as a Stockholder. (i) Any Award granted hereunder shall be exercisable at such times and under such conditions as determined by the Administrator under the terms of the Plan and specified in the Award Agreement. (ii) An Award shall be deemed to be exercised when written notice of such exercise has been given to the Company in accordance with the terms of the Award by the person entitled to exercise the Award and full payment for the Shares with respect to which the Award is exercised, including, to the extent selected, use of the broker-dealer sale and remittance procedure to pay the purchase price as provided in Section 7(b)(v). Until the issuance (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company) of the stock certificate evidencing such Shares, no right to vote or receive dividends or any other rights as a stockholder shall exist with respect to Shares subject to an Award, notwithstanding the exercise of an Option or other Award. The Company shall issue (or cause to be issued) such stock certificate promptly upon exercise of the Award. No adjustment will be made for a dividend or other right for which the record date is prior to the date the stock certificate is issued, except as provided in the Award Agreement or Section 10, below. (b) Exercise of Award Following Termination of Continuous Service. (i) An Award may not be exercised after the termination date of such Award set forth in the Award Agreement and may be exercised following the termination of a Grantee's Continuous Service only to the extent provided in the Award Agreement. (ii) Where the Award Agreement permits a Grantee to exercise an Award following the termination of the Grantee's Continuous Service for a specified period, the Award shall terminate to the extent not exercised on the last day of the specified period or the last day of the original term of the Award, whichever occurs first. (iii) Any Award designated as an Incentive Stock Option to the extent not exercised within the time permitted by law for the exercise of Incentive Stock Options following the termination of a Grantee's Continuous Service shall convert automatically to a Non-Qualified Stock Option and thereafter shall be exercisable as such to the extent exercisable by its terms for the period specified in the Award Agreement. (c) Buyout Provisions. The Administrator may at any time offer to buy out for a payment in cash or Shares, an Award previously granted, based on such terms and conditions as the Administrator shall establish and communicate to the Grantee at the time that such offer is made. 9. Conditions Upon Issuance of Shares. (a) Shares shall not be issued pursuant to the exercise of an Award unless the exercise of such Award and the issuance and delivery of such Shares pursuant thereto shall 12

32 comply with all Applicable Laws, and shall be further subject to the approval of counsel for the Company with respect to such compliance. (b) As a condition to the exercise of an Award, the Company may require the person exercising such Award to represent and warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation is required by any Applicable Laws. 10. Adjustments Upon Changes in Capitalization. Subject to any required action by the shareholders of the Company, the number of Shares covered by each outstanding Award, and the number of Shares which have been authorized for issuance under the Plan but as to which no Awards have yet been granted or which have been returned to the Plan, the exercise or purchase price of each such outstanding Award, as well as any other terms that the Administrator determines require adjustment shall be proportionately adjusted for (i) any increase or decrease in the number of issued Shares resulting from a stock split, reverse stock split, stock dividend, combination or reclassification of the Shares, (ii) any other increase or decrease in the number of issued Shares effected without receipt of consideration by the Company, or (iii) as the Administrator may determine in its discretion, any other transaction with respect to Common Stock to which Section 424(a) of the Code applies; provided, however that conversion of any convertible securities of the Company shall not be deemed to have been "effected without receipt of consideration." Such adjustment shall be made by the Administrator and its determination shall be final, binding and conclusive. Except as the Administrator determines, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason hereof shall be made with respect to, the number or price of Shares subject to an Award. 11. Corporate Transactions/Changes in Control/Related Entity Dispositions. Except as may be provided in an Award Agreement: (a) Effective upon the consummation of a Corporate Transaction, all outstanding Awards under the Plan shall terminate. However, all such Awards shall not terminate if they are, in connection with the Corporate Transaction, assumed by the successor corporation or Parent thereof. (b) Effective upon the consummation of a Related Entity Disposition, for purposes of the Plan and all Awards, the Continuous Service of each Grantee who is at the time engaged primarily in service to the Related Entity involved in such Related Entity Disposition shall terminate and each Award of such Grantee which is at the time outstanding under the Plan shall be exercisable in accordance with the terms of the Award Agreement evidencing such Award. However, such Continuous Service shall be not to deemed to terminate if such Award is, in connection with the Related Entity Disposition, assumed by the successor entity or its parent. 12. Effective Date and Term of Plan. The Plan shall become effective upon the earlier to occur of its adoption by the Board or its approval by the stockholders of the Company. It shall continue in effect for a term of ten (10) years unless sooner terminated. Subject to 13

33 Section 16, below, and Applicable Laws, Awards may be granted under the Plan upon its becoming effective. 13. Amendment, Suspension or Termination of the Plan. (a) The Board may at any time amend, suspend or terminate the Plan. To the extent necessary to comply with Applicable Laws, the Company shall obtain stockholder approval of any Plan amendment in such a manner and to such a degree as required. (b) No Award may be granted during any suspension of the Plan or after termination of the Plan. (c) Any amendment, suspension or termination of the Plan (including termination of the Plan under Section 12, above) shall not affect Awards already granted, and such Awards shall remain in full force and effect as if the Plan had not been amended, suspended or terminated, unless mutually agreed otherwise between the Grantee and the Administrator, which agreement must be in writing and signed by the Grantee and the Company. 14. Reservation of Shares. (a) The Company, during the term of the Plan, will at all times reserve and keep available such number of Shares as shall be sufficient to satisfy the requirements of the Plan. (b) The inability of the Company to obtain authority from any regulatory body having jurisdiction, which authority is deemed by the Company's counsel to be necessary to the lawful issuance and sale of any Shares hereunder, shall relieve the Company of any liability in respect of the failure to issue or sell such Shares as to which such requisite authority shall not have been obtained. 15. No Effect on Terms of Employment/Consulting Relationship. The Plan shall not confer upon any Grantee any right with respect to the Grantee's Continuous Service, nor shall it interfere in any way with his or her right or the Company's right to terminate the Grantee's Continuous Service at any time, with or without cause. 16. No Effect on Retirement and Other Benefit Plans. Except as specifically provided in a retirement or other benefit plan of the Company or a Related Entity, Awards shall not be deemed compensation for purposes of computing benefits or contributions under any retirement plan of the Company or a Related Entity, and shall not affect any benefits under any other benefit plan of any kind or any benefit plan subsequently instituted under which the availability or amount of benefits is related to level of compensation. The Plan is not a "Retirement-Plan" or "Welfare Plan" under the Employee Retirement Income Security Act of 1974, as amended. 17. Stockholder Approval. The Plan became effective when adopted by the Board in January 1999. On March 7, 2000, the Board adopted and approved an amendment and restatement of the Plan (a) to increase the number of Shares available for issuance under the Plan and (b) to adopt a limit on the maximum number of Shares with respect to which Options may be 14

34 granted to any Grantee in any fiscal year of the Company and certain other administrative provisions to comply with the performance-based compensation exception to the deduction limit of Section 162(m) of the Code, which amendments are subject to approval by the stockholders of the Company. 15
