To transact such other business as properly may come before the Meeting or any continuation, adjournment or postponement thereof. METHOD OF VOTING Stockholders can vote by proxy or by attending the Meeting and voting in person. A proxy card (the "Proxy") is enclosed. If you vote by means of the Proxy, the Proxy must be completed, signed and dated by you or your authorized representative. The completed Proxy may be returned in the postage-paid envelope provided, or by facsimile to the Inspector of Elections at (805) 374-1255. C.H. Chen and Carl C. Wertz, the designated proxyholders (the "Proxyholders"), are members of the Company's management. If you hold Common Stock in "street name," you must either instruct your broker or nominee as to how to vote such shares or obtain a proxy, executed in your favor by your broker or nominee, to be able to vote at the Meeting. If a Proxy is properly signed, dated and returned and is not revoked, the Proxy will be voted at the Meeting in accordance with the Stockholder's instructions indicated on the Proxy. If no instructions are indicated on the Proxy, the Proxy will be voted "FOR" the election of the Board of Directors' nominees, "FOR" ratification of the appointment of Moss Adams LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2005 and in accordance with the recommendations of the Board of Directors as to any other matter that may properly be brought before the Meeting or any continuation, adjournment or postponement thereof. 2

REVOCATION OF PROXIES You may revoke a Proxy at any time before it is exercised by filing a written revocation, or a duly executed proxy bearing a later date, with the Company's Secretary at our principal executive offices located at 3050 East Hillcrest Drive, Westlake Village, California 91362 prior to the commencement of the Meeting. You may also revoke a Proxy by attending the Meeting and voting in person. Stockholders whose shares are held in "street name" should consult with their broker or nominee concerning the method for revoking their Proxy. VOTING RIGHTS The authorized capital of the Company consists of (i) 30,000,000 shares of common stock, par value $0.66-2/3 per share ("Common Stock"), of which 14,300,883 shares were issued and outstanding on the Record Date (with an additional 1,613,508 shares held as treasury stock) and (ii) 1,000,000 shares of Class A Preferred Stock, $1.00 par value ("Class A Preferred Stock"), none of which were issued and outstanding on the Record Date. The Common Stock and the Class A Preferred Stock are collectively referred to as the "Stock." A majority of the shares of Common Stock issued and outstanding and entitled to vote at the meeting, present either in person or by Proxy, constitutes a quorum for the conduct of business at the Meeting. Votes withheld, abstentions and "broker non-votes" (as defined below) will be counted for the purpose of determining the presence of a quorum. Each Stockholder is entitled to one vote, in person or by proxy, for each share of Common Stock standing in his or her name on the books of the Company at the close of business on the Record Date on any matter submitted to the Stockholders, except that in connection with the election of directors, each Stockholder has the right to cumulate votes, provided that the candidates' names have been properly placed in nomination prior to commencement of voting and a Stockholder has given notice prior to commencement of voting of his or her intention to cumulate votes. If a Stockholder has given such notice, all Stockholders may cumulate their votes for all nominated candidates. Cumulative voting entitles a Stockholder to give one candidate a number of votes equal to the number of directors to be elected multiplied by the number of shares of Common Stock owned by such Stockholder, or to distribute such Stockholder's votes on the same principle among as many candidates as the Stockholder shall think fit. The candidates receiving the highest number of votes, up to the number of directors to be elected, shall be elected. Discretionary authority to cumulate votes is hereby solicited by the Board of Directors and the return of the Proxy shall grant such authority. Each proposal described in this Proxy Statement, other than the election of directors, requires the affirmative vote of a majority of the outstanding shares of Common Stock present, in person or by proxy, and entitled to vote at the Meeting. Abstentions on any proposal submitted to the Stockholders, other than the election of directors, will be included in the number of votes cast on that proposal and, accordingly, will have the effect of a vote "AGAINST" the proposal. However, broker non-votes with respect to a proposal will not be included in the number of shares counted as being present for the purposes of voting on that proposal and, accordingly, will have the effect of reducing the number of affirmative votes required to approve the proposal. Of the shares of Common Stock outstanding on the Record Date, 4,601,458 (or approximately 32.2%) (the "Shares") were held in the name of Lite-On Semiconductor Corporation ("LSC"), formerly named Lite-On Power Semiconductor ("LPSC"). See "General Information - Security Ownership of Certain Beneficial Owners and Management" and "Proposal One - Election of Directors - Certain Relationships and Related Transactions" for a discussion of the relationship between LPSC, LSC and the Company. An additional 104,318 shares (or approximately 0.7%) were owned by directors and executive officers of the Company on the Record Date. LSC and each director and executive officer has informed the Company that they will vote "FOR" the election of the nominees to the Board of Directors identified herein, and "FOR" the appointment of Moss Adams LLP as the Company's independent registered public accounting firm. Brokers holding Common Stock in "street name" who are members of a stock exchange are required by the rules of the exchange to transmit this Proxy Statement to the beneficial owner of the Common Stock and to solicit voting instructions with respect to the matters submitted to the Stockholders. If the broker has not received instructions from the beneficial owner by the date specified in the statement accompanying such material, the broker may give or authorize the giving of a Proxy to vote the Common Stock in his discretion as to the election of directors or the appointment of the independent registered public accounting firm. However, brokers or nominees do not have 3

discretion to vote on certain other proposals without specific instructions from the beneficial owner. When a broker or nominee is unable to vote a client's shares on proposals, the missing votes are referred to as "broker non-votes." If you hold Common Stock in "street name"and you fail to instruct your broker or nominee as to how to vote such Common Stock, your broker or nominee may, in its discretion, vote such Common Stock "FOR" the election of the Board of Director's nominees and "FOR" ratification of the appointment of Moss Adams LLP as the Company's independent registered public accounting firm. COST OF SOLICITATION OF PROXIES This Proxy solicitation is made by the Board of Directors of the Company, and the Company will bear the costs of this solicitation, including the expense of preparing, assembling, printing and mailing this Proxy Statement and any other material used in this solicitation of Proxies. If it should appear desirable to do so to ensure adequate representation at the Meeting, officers and regular employees may communicate with Stockholders, beneficial owners, banks, brokerage houses, custodians, nominees and others, by telephone, facsimile transmissions, telegraph, e-mail or in person to request that Proxies be furnished. No additional compensation will be paid for these services to officers or employees of the Company. The Company will reimburse banks, brokerage houses, and other custodians, nominees and fiduciaries, for their reasonable expenses in forwarding proxy materials to their principals. The total estimated cost for the printing and solicitation of Proxies is $10,000. OTHER BUSINESS As of the date of this Proxy Statement, the Board of Directors knows of no business to be presented for consideration at the Meeting other than as stated in the Notice of Annual Meeting. However, if any other matters properly come before the Meeting, including a motion to adjourn the Meeting to another time or place to solicit additional Proxies in favor of the recommendation of the Board of Directors, the Proxyholders will vote the shares represented by the Proxies on such matters and authority to do so is included in the Proxy. On such matters, in accordance with the recommendations of the Board of Directors, such authorization includes authority to appoint a substitute nominee or nominees to the Board of Directors' nominees identified herein where death, illness or other circumstances arise which prevent any such nominee for directors from serving in such position and to vote such Proxy for such substitute nominee. 4

(2) The named stockholder has sole voting power and investment power with respect to the shares listed, except as indicated and subject to community property laws where applicable. (3) Under Rule 13d-3 of the Securities and Exchange Act of 1934 (the "Exchange Act"), certain shares may be deemed to be beneficially owned by more than one person (if, for example, a person shares the power to vote or the power to dispose of the shares). In addition, under Rule 13d-3(d)(1) of the Exchange Act, shares which the person (or group) has the right to acquire within 60 days after the Record Date are deemed to be outstanding in calculating the beneficial ownership and the percentage ownership of the person (or group) but are not deemed to be outstanding as to any other person or group. As a result, the percentage of outstanding shares of any person as shown in this table does not necessarily reflect the person's actual ownership of voting power with respect to the number of shares of Common Stock actually outstanding at the Record Date.

MEETINGS OF THE BOARD AND COMMITTEES The Board of Directors held four meetings during 2004. The Audit Committee held 9 meetings, and the Compensation and Stock Options Committee and the Nominating Committee both held one meeting during 2004.

All of the persons who were directors of the Company or members of committees were present for at least 75% of the meetings during 2004. NOMINATING PROCEDURES AND CRITERIA Among its functions, the Nominating Committee considers and approves nominees for election to the Board of Directors. In addition to the candidates proposed by the Board of Directors or identified by the committee, the committee considers candidates for director suggested by stockholders provided such recommendations are made in accordance with the procedures set forth under "Proposals of Stockholders and Stockholder Nominations for 2006 Annual Meeting." Stockholder nominations that comply with these procedures and meet the criteria outlined below will receive the same consideration that the committee's nominees receive. Essential criteria for all candidates considered by the Nominating Committee include the following: integrity and ethical behavior, maturity, management experience and expertise, independence and diversity of thought and broad business or professional experience, with an understanding of business and financial affairs and the complexities of business organizations. In evaluating candidates for certain Board positions, the committee evaluates additional criteria, including the following: financial or accounting expertise; experience in the semiconductor industry or other technology industries; scientific accomplishment; experience in commercializing and marketing semiconductors or other electronic components; business and other experience relevant to public companies of a size comparable to the Company; and experience in investment banking, commercial lending or other financing activities. In selecting nominees for the Board of Directors, the committee evaluates the general and specialized criteria set forth above, identifying the relevant specialized criteria prior to commencement of the recruitment process, considers previous performance if the candidate is candidate for re-election, and generally considers the candidate's ability to contribute to the success of he Company. The Nominating Committee, as well as the full Board of Directors, has recommended the Board of Directors' nominees for the Meeting. Stockholders did not propose any candidates for election at the Meeting.

These amounts represent certain assumed rates of appreciation only. For example, an $18.32 per share price with a 5% annual growth rate for 10 years results in a stock price of $29.84 per share and a 10% growth rate results in a price of $47.52 per share. Actual gains, if any, on stock option exercises are dependent upon a variety of factors, including market conditions and the price performance of the Common Stock. No assurance can be made that the rate of appreciation presented in this table can be achieved.

(2) Represents shares of Common Stock that may be issued pursuant to future awards under the Incentive Bonus Stock Plan and the 2001 Omnibus Equity Incentive Plan. EMPLOYEE BENEFITS PLANS 1993 ISO PLAN The 1993 Incentive Stock Option Plan (the "1993 ISO Plan") provides for the grant of incentive stock options within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the "Code"), to purchase up to 2,250,000 shares (split adjusted) of the Company's Common Stock. Options granted under the 1993 ISO Plan are not transferable, except by will or the laws of descent or distribution. A vested but unexercised option is normally exercisable for 90 days after termination of employment, other than by death or retirement. In the event of death, unvested options are accelerated to maturity. An option granted under the 1993 ISO Plan may not be priced at less than 100% of fair market value on the date of grant and expires ten years from the date of grant. As of the Record Date, 1,596,908 shares have been issued on the exercise of options granted and 629,125 shares were subject to outstanding options under the 1993 ISO Plan. The 1993 ISO Plan expired on May 10, 2003, and, therefore, no additional options can be granted. 16

1993 NQO PLAN The 1993 Non-Qualified Stock Option Plan (the "1993 NQO Plan") became effective on July 6, 1993. The 1993 NQO Plan provides for the grant of options that do not qualify as incentive stock options under Section 422 of the Code to purchase up to 2,250,000 shares (split adjusted) of the Company's Common Stock. The options may be exercised by the optionee during his or her lifetime or after his or her death by those who have inherited by will or intestacy. A vested but unexercised option is normally exercisable for 90 days after termination of employment, other than by death or retirement. In the event of death, unvested options are accelerated to maturity. The shares to be issued upon exercise of options under the 1993 NQO Plan require a three-year vesting period. An option granted under the 1993 NQO Plan may not be priced at less than 100% of fair market value on the date of grant and expires ten years from the date of grant. As of the Record Date, 1,663,650 shares have been issued on the exercise of options granted and 566,100 shares were subject to outstanding options under the 1993 NQO Plan. The 1993 NQO Plan expired on May 10, 2003, and, therefore, no additional options can be granted. 2001 OMNIBUS EQUITY INCENTIVE PLAN GENERAL. In April 2001, the 2001 Omnibus Equity Incentive Plan (the "2001 Incentive Plan") became effective. Under the 2001 Incentive Plan, employees, non-employee directors and consultants of the Company and its subsidiaries are eligible to receive shares of Common Stock of the Company or other securities or benefits with a value derived from the value of the Common Stock of the Company. The purpose of the 2001 Incentive Plan is to enable the Company to attract, retain and motivate employees, non-employee directors and consultants by providing for or increasing their proprietary interests in the Company and, thereby, further align their interests with those of the Company's stockholders. The maximum number of shares of Common Stock that may be issued pursuant to awards granted under the 2001 Incentive Plan may not exceed the sum of (i) 1,500,000 shares (split adjusted) and (ii) on each January 1, an additional number of shares equal to 1% of the total number of shares of Common Stock outstanding on the immediately preceding December 31; provided, however, that the maximum number of shares of Common Stock that may be issued pursuant to incentive stock options under the 2001 Incentive Plan may not exceed 3,000,000 shares (split adjusted). As of the Record Date, 94,850 shares have been issued on the exercise of options granted, 1,385,300 shares were subject to outstanding options, and 597,362 shares were available for issuance under awards that may be granted under the 2001 Incentive Plan. ADMINISTRATION. The 2001 Incentive Plan is administered by the Compensation and Stock Options Committee of the Board of Directors (the "Committee"). Subject to the provisions of the 2001 Incentive Plan, the Committee has a wide degree of flexibility in determining the terms and conditions of awards and the number of shares to be issued pursuant thereto, including conditioning the receipt or vesting of awards upon the achievement by the Company of specified performance criteria. The expenses of administering the 2001 Incentive Plan are borne by the Company. TERMS OF AWARDS. The 2001 Incentive Plan authorizes the Committee to enter into any type of arrangement with an eligible recipient that, by its terms, involves or might involve the issuance of Common Stock or any other security or benefit with a value derived from the value of Common Stock. Awards are not restricted to any specified form or structure and may include, without limitation, sales or bonuses of stock, restricted stock, stock options, reload options, stock appreciation rights, phantom stock, dividend equivalents, performance units or performance shares. An award may consist of one such security or benefit or two or more of them in tandem or in the alternative. 17

An award granted under the 2001 Incentive Plan may include a provision accelerating the receipt of benefits upon the occurrence of specified events, such as a change of control of the Company or a dissolution, liquidation, merger, reclassification, sale of substantially all of the property and assets of the Company or other significant corporate transactions. The Committee may grant options that either are intended to be "incentive stock options" as defined under Section 422 of the Code, or are not intended to be incentive options ("non-qualified stock options"). Incentive stock options may be granted only to employees. No incentive stock option may be granted under the 2001 Incentive Plan to any person who, at the time of the grant, owns (or is deemed to own) stock possessing more than 10% of the total combined voting power of the Company or any affiliate of the Company, unless the option exercise price is at least 110% of the fair market value of the stock subject to the option on the date of the grant and the term of the option does not exceed five years from the date of the grant. In addition, the aggregate fair market value, determined at the time of the grant, of the shares of Common Stock with respect to which incentive stock options are exercisable for the first time by an optionee during any calendar year (under all such plans of the Company and its subsidiaries) may not exceed $100,000. As a result of enactment of Section 162(m) of the Code, and to provide the Committee flexibility in structuring awards, the 2001 Incentive Plan states that in the case of stock options and stock appreciation rights, no person may receive in any year a stock option to purchase more than 100,000 shares or a stock appreciation right measured by more than 100,000 shares. If awards granted under the 2001 Incentive Plan expire, are canceled or otherwise terminate without being exercised, the Common Stock not purchased pursuant to the award again becomes available for issuance under the 2001 Incentive Plan. Awards may not be granted under the 2001 Incentive Plan on or after the tenth anniversary of the adoption of the 2001 Incentive Plan. PAYMENT OF EXERCISE PRICE. An award may permit the recipient to pay all or part of the purchase price of the shares or other property issuable pursuant thereto, or to pay all or part of such recipient's tax withholding obligation with respect to such issuance, by (i) delivering previously owned shares of capital stock of the Company or other property or (ii) reducing the amount of shares or other property otherwise issuable pursuant to the award or (iii) delivering a promissory note, the terms and conditions of which will be determined by the Committee. The exercise price and any withholding taxes are payable in cash by consultants and non-employee directors, although the Committee at its discretion may permit such payment by delivery of shares of Common Stock, or by delivery of broker instructions authorizing a loan secured by the shares acquired upon exercise or payment of proceeds from the sale of such shares. AMENDMENT. Subject to limitations imposed by law, the Board may amend or terminate the 2001 Incentive Plan at any time and in any manner. However, no such amendment or termination may deprive the recipient of any award previously granted under the 2001 Incentive Plan or any rights thereunder without the recipient's consent. SECTION 16(B). Pursuant to Section 16(b) of the Exchange Act, directors, certain officers and ten percent shareholders of the Company are generally liable to the Company for repayment of any "short-swing" profits realized from any non-exempt purchase and sale of Common Stock occurring within a six-month period. Rule 16b-3, promulgated under the Exchange Act, provides an exemption from Section 16(b) liability for certain transactions by an officer or director pursuant to an employee benefit plan that complies with such Rule. Specifically, the grant of an option under an employee benefit plan that complies with Rule 16b-3 will not be deemed a purchase of a security for purposes of Section 16(b). The 2001 Incentive Plan is designed to comply with Rule 16b-3. TERM. Awards may not be granted under the 2001 Incentive Plan on or after the tenth anniversary of the adoption of the 2001 Incentive Plan. Although any award that was duly granted on or prior to such date may thereafter be exercised or settled in accordance with its terms, no shares of Common Stock may be issued pursuant to any award on or after the twentieth anniversary of the adoption of the 2001 Incentive Plan. PERFORMANCE GOALS. The business criteria on which performance goals are based under the 2001 Incentive Plan will be determined on a case-by-case basis, except that with respect to stock options and stock appreciation rights compensation is based on increases in the value of the Common Stock after the date of grant of award. Similarly, the maximum amount of compensation that could be paid to any participant or the formula used to calculate the amount of compensation to be paid to the participant if a performance goal is obtained will be determined on a case-by-case basis, except that in the case of stock options the maximum possible compensation will be calculated as the difference between the exercise price of the option and the fair market value of the Common Stock on the date of option exercise, times the maximum number of shares for which grants may be made to any participant. ADJUSTMENTS. If there is any change in the stock subject to the 2001 Incentive Plan or subject to any award made under the 2001 Incentive Plan (through merger, consolidation, reorganization, re-capitalization, stock dividend, dividend in kind, stock split, liquidating dividend, combination or exchange of shares, change in corporate structure or otherwise), the 2001 Incentive Plan and shares outstanding thereunder will be appropriately adjusted as to the class and the maximum number of shares subject to the 2001 Incentive Plan and the class, number of shares and price per share of stock subject to such outstanding options as determined by the Committee to be fair and equitable to 18

the holders, the Company and the shareholders. In addition, the Committee may also make adjustments in the number of shares covered by, and the price or other value of any outstanding awards under the 2001 Incentive Plan in the event of a spin-off or other distribution (other than normal cash dividends) of Company assets to stockholders. INCENTIVE BONUS STOCK PLAN The Company's Incentive Bonus Stock Plan provides that the Board of Directors may fix a dollar value to an employee bonus and determine to pay such bonus in the form of shares of the Common Stock of the Company. The number of shares to be awarded to the employee is determined by dividing the dollar amount of the bonus by the fair market value of one share of Common Stock. The Board of Directors may also elect to grant a number of shares of Common Stock to the employee. As of the Record Date, 279,000 shares of Common Stock were available for issuance under the Incentive Bonus Stock Plan. 401(K) PLAN The Company maintains a 401(k) profit sharing plan (the Plan) for the benefit of qualified employees at its North American locations. Employees who participate may elect to make salary deferral contributions to the Plan up to 100% of the employees' eligible payroll subject to annual Internal Revenue Code maximum limitations. The Company makes a matching contribution of $1 for every $2 contributed by the participant up to 6% (3% maximum matching) of the participant's eligible payroll. In addition, the Company may make a discretionary contribution to the entire qualified employee pool, in accordance with the Plan. As stipulated by the regulations of the PRC, the Company maintains a retirement plan pursuant to the local Municipal Government for its employees in China. The Company is required to make contributions to the retirement plan at a rate of 22.5% of the employee's eligible payroll. Pursuant to the Taiwan Labor Standard Law and Factory Law, the Company maintains a retirement plan for its employees in Taiwan. The Company makes contributions at a rate of 6% of the employee's eligible payroll. EMPLOYMENT CONTRACTS AND TERMINATION OF EMPLOYMENT AND CHANGE IN CONTROL ARRANGEMENTS None. REPORT OF THE COMPENSATION AND STOCK OPTIONS COMMITTEE OF THE BOARD OF DIRECTORS TO STOCKHOLDERS THE REPORT OF THE COMPENSATION AND STOCK OPTIONS COMMITTEE OF THE BOARD OF DIRECTORS SHALL NOT BE DEEMED INCORPORATED BY REFERENCE BY ANY GENERAL STATEMENT INCORPORATING BY REFERENCE THIS PROXY STATEMENT INTO ANY FILING UNDER THE SECURITIES ACT OF 1933 OR UNDER THE SECURITIES EXCHANGE ACT OF 1934, EXCEPT TO THE EXTENT THAT THE COMPANY SPECIFICALLY INCORPORATES THIS INFORMATION BY REFERENCE, AND SHALL NOT OTHERWISE BE DEEMED FILED UNDER SUCH ACTS. REPORT OF THE COMPENSATION AND STOCK OPTIONS COMMITTEE GENERAL The Compensation and Stock Options Committee (the "Committee") consists of three directors, Michael R. Giordano (Chairman), John M. Stich and Dr. Keh-Shew Lu. The Board of Directors has determined that each member of the Committee is "independent" as that term is defined under the rules of Nasdaq. The Committee determines the compensation of the executive officers of the Company. The Committee also administers the Company's equity incentive plans and 401(k) plan. The Compensation Committee operates under a written charter approved by the Board of Directors. COMPENSATION PHILOSOPHY The Company's compensation programs are designed to attract, retain and motivate executives critical to the Company's long-term growth and profitability. Compensation of executive officers consists of base salaries, performance-based incentive bonuses, and long-term equity incentive awards. The Compensation Committee's policy 19

generally is to design the total compensation package to be competitive with the total compensation paid to executives of other companies in the Company's industry that are of similar size. Bonus programs and equity incentives plans are designed to motivate our executives to achieve strategic objectives and performance objectives established by the Board of Directors. BASE SALARIES Executive officers receive a relatively small portion of their total compensation as base salary. Base salaries are generally at or below the median base salaries paid to officers with comparable duties by other companies in our industry that are of a similar size. The Compensation Committee periodically reviews an independent survey of executive compensation. Salaries are established by the Compensation Committee based on its subjective assessment of the executive's scope of responsibility, level of experience, individual performance, and past and potential contribution to the Company's business. BONUSES Performance-based incentive bonuses are based upon the achievement of specific financial performance objectives established at the beginning of each fiscal year. Bonuses are primarily based upon (i) the Company's revenue growth exceeding that of the Company's industry and (ii) the growth in the Company's net income over the prior year. EQUITY INCENTIVES The Compensation Committee believes that long-term equity incentive awards serve to align the interests of the executive officers with those of the Company's stockholders. Under the 2001 Omnibus Equity Incentive Plan, the Company may grant any type of award whose value is derived from the value of the Common Stock of the Company, including shares of Common Stock, options and stock appreciation rights. To date, the Company has only granted stock options under its equity incentive plans. The exercise price of the stock options granted to date has been no less than the fair market value of the Common Stock as of the date of grant. To encourage retention, the ability to exercise the option is subject to vesting restrictions. The Compensation Committee's policy is to award options annually, which generally vest over three years, and are in recognition of the executive officer's current and potential contribution to the Company. Decisions made by the Compensation Committee regarding the timing and size of subsequent option grants take into consideration the Company's and the individual's performance, competitive market practices, and the size and term of option grants made in prior years. COMPENSATION FOR THE PRESIDENT AND CHIEF EXECUTIVE OFFICER Mr. C.H. Chen was appointed President, Chief Executive Officer, and a director of the Company in March 2000. Mr. Chen also serves as the Vice Chairman of LSC, a Lite-On Group company, for which he is also compensated by LSC. The Committee believes that Mr. Chen's base salary of $150,000 is substantially below that of the chief executive officers of other companies in the Company's industry. Mr. Chen's bonus of $383,700 in 2004 was based upon the achievement of specific financial performance objectives established at the beginning of that year and relating to the Company's growth in revenue and net income over the prior year (specifically, for 2004, the Company increased revenue 35.6%, while the industry grew 18.9%, and the Company increased net income 153% from $10.1 million to $25.6 million). Stock options granted to Mr. Chen in 2004 are based upon the Committee's subjective assessment of the performance of Mr. Chen and the Company. 20

DEDUCTIBILITY OF COMPENSATION Under Section 162(m) of the Internal Revenue Code of 1986, as amended (the "Code"), a public company generally will not be entitled to a deduction for non-performance-based compensation paid to certain executive officers to the extent such compensation exceeds $1.0 million. Special rules apply for "performance-based" compensation, including the approval of the performance goals by the stockholders of the Company. The stockholders of the Company have approved each of the Company's incentive plans for the purpose of qualifying those plans under Section 162(m). Therefore, the Compensation Committee believes that all compensation paid to the Company's executive officers in fiscal 2004 will be fully deductible. In order to maintain flexibility in compensating executive officers in a manner designed to promote the Company's goals, the Compensation Committee reserves the right to award future compensation which would not comply with Section 162(m) if it concludes that this is in the Company's best interests. Dated: April 13, 2005 COMPENSATION AND STOCK OPTIONS COMMITTEE OF THE BOARD OF DIRECTORS OF DIODES INCORPORATED Michael R. Giordano, CHAIRMAN Dr. Keh-Shew Lu John M. Stich COMPENSATION AND STOCK OPTIONS COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION The Compensation and Stock Options Committee consists of three directors, Michael R. Giordano (Chairman), Dr. Keh-Shew Lu and John M. Stich. No person who served as a member of the Company's Compensation and Stock Options Committee during 2004 has ever been an officer or employee of the Company or any of its subsidiaries. During 2004, no executive officer of the Company served on the compensation committee (or equivalent), of the Board of Directors, of another entity whose executive officer(s) served on the Company's Compensation and Stock Options Committee or Board of Directors. REPORT OF THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS TO STOCKHOLDERS THE REPORT OF THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS SHALL NOT BE DEEMED INCORPORATED BY REFERENCE BY ANY GENERAL STATEMENT INCORPORATING BY REFERENCE THIS PROXY STATEMENT INTO ANY FILING UNDER THE SECURITIES ACT OF 1933 OR UNDER THE SECURITIES EXCHANGE ACT OF 1934, EXCEPT TO THE EXTENT THAT THE COMPANY SPECIFICALLY INCORPORATES THIS INFORMATION BY REFERENCE, AND SHALL NOT OTHERWISE BE DEEMED FILED UNDER SUCH ACTS. REPORT OF THE AUDIT COMMITTEE The Board of Directors maintains an Audit Committee comprised of three of the Company's directors, Michael R. Giordano (Chairman), Dr. Keh-Shew Lu and John M. Stich. Each member of the Audit Committee meets the independence and experience requirements of the Nasdaq Stock Market. Mr. Giordano qualifies as an "audit committee financial expert" as defined under the rules of the SEC. The Audit Committee assists the Board of Directors in monitoring the accounting, auditing and financial reporting practices of the Company. Management is responsible for the preparation of the Company's financial statements and financial reporting process, including its system of internal controls. In fulfilling its oversight responsibilities, the Audit Committee: o Reviewed and discussed with management the audited financial statements contained in the Company's Annual Report on Form 10-K for fiscal 2004; and o Obtained from management their representation that the Company's financial statements have been prepared in accordance with accounting principles generally accepted in the United States. 21

The independent registered public accounting firm is responsible for performing an audit of the Company's financial statements in accordance with the auditing standards generally accepted in the United States and expressing an opinion on whether the Company's financial statements present fairly, in all material respects, the Company's financial position and results of operations for the periods presented and conform with accounting principles generally accepted in the United States. In fulfilling its oversight responsibilities, the Audit Committee: o Discussed with the independent registered public accounting firm the matters required to be discussed by Statement on Auditing Standards No. 61, as amended ("Communication with Audit Committees"); and o Received and discussed with the independent registered public accounting firm the written disclosures and the letter from the independent registered public accounting firm required by Independent Standards Board Standard No. 1 ("Independence Discussions with Audit Committees"), and reviewed and discussed with the independent registered public accounting firm whether the rendering of the non-audit services provided by them to the Company during fiscal 2004 was compatible with their independence. The Audit Committee operates under a written charter, which was adopted by the Board of Directors and is assessed annually for adequacy by the Audit Committee. On April 8, 2004, the Audit Committee recommended, and the Board of Directors adopted, an amended charter for the committee. The Audit Committee held nine meetings during fiscal 2004. In performing its functions, the Audit Committee acts only in an oversight capacity. It is not the responsibility of the Audit Committee to determine that the Company's financial statements are complete and accurate, are presented in accordance with accounting principles generally accepted in the United States or present fairly the results of operations of the Company for the periods presented or that the Company maintains appropriate internal controls. Nor is it the duty of the Audit Committee to determine that the audit of the Company's financial statements has been carried out in accordance with generally accepted auditing standards or that the Company's auditors are independent. Based upon the reviews and discussions described above, and the report of the independent registered public accounting firm, the Audit Committee has recommended to the Board of Directors, and the Board of Directors has approved, that the audited financial statements be included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2004 for filing with the Securities and Exchange Commission. The Audit Committee also has recommended, and the Board of Directors also has approved, subject to stockholder ratification, the selection of Moss Adams LLP as the Company's independent registered public accounting firm for the fiscal year ending December 31, 2005. Dated: April 13, 2005 THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS OF DIODES INCORPORATED, Michael R. Giordano, CHAIRMAN Dr. Keh-Shew Lu John M. Stich CODE OF ETHICS The Company has adopted a Code of Ethics applicable to the principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions of the Company. The Code of Ethics is published on our website, at www.diodes.com. We intend to disclose future amendments to, or waivers from, certain provisions of the Code of Ethics applicable to senior financial executives on our website within two business days following the date of such amendment or waiver. 22

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS The Company conducts business with two related party companies, LSC (and its subsidiaries) and Keylink International (formerly Xing International) (and its subsidiaries). LSC, a 32.5% shareholder at December 31, 2004, is the Company's largest shareholder, and Keylink International is owned by the Company's 5% joint venture partner in Diodes-China and Diodes-Shanghai. C.H. Chen, the Company's President and Chief Executive Officer, and a member of the Company's Board of Directors, is also Vice-Chairman of LSC. M.K. Lu, a member of the Company's 23

Board of Directors, is President of LSC, while Raymond Soong, the Company's Chairman of the Board, is the Chairman of The Lite-On Group, a significant shareholder of LSC. The Audit Committee reviews all related party transactions for potential conflict of interest situations, and approves all such transactions, in accordance with such procedures as it may adopt from time to time. The Company believes that all related party transactions are on terms no less favorable to the Company than would be obtained from unaffiliated third parties. In 2004, the Company sold silicon wafers to LSC totaling 11.1% (10.7% in 2003) of the Company's sales, making LSC the Company's largest customer. Also for 2004, 17.2% (17.3% in 2003) of the Company's sales were from discrete semiconductor products purchased from LSC, making LSC the Company's largest outside vendor. Under a long-standing sales agreement, the Company is the exclusive North American distributor for certain LSC product lines. In addition, the Company leases warehouse space from LSC for its operations in Hong Kong. Such transactions are on terms no less favorable to the Company than could be obtained from unaffiliated third parties. The Audit Committee of the Board of Directors has approved the contracts associated with the related party transactions. In December 2000, the Company acquired a wafer foundry, FabTech, Inc., from LSC. As part of the purchase price, at December 31, 2004, LSC holds a subordinated, interest-bearing note for approximately $3.8 million. In May 2002, the Company renegotiated the terms of the note to extend the payment period from two years to four years, and, as a result, monthly payments of approximately $208,000 plus interest began in July 2002. In connection with the acquisition, LSC entered into a volume purchase agreement to purchase wafers from FabTech. In addition, in accordance with the terms of the acquisition, the Company has entered into several management incentive agreements with members of FabTech's management. The agreements provide members of FabTech's management guaranteed annual payments as well as contingent bonuses based on the annual profitability of FabTech, subject to a maximum annual amount. Any portion of the guaranteed and contingent liability paid by FabTech is reimbursed by LSC. 2004 is the final year of the management incentive agreements, with final payment made by March 31, 2005. In 2004, the Company sold silicon wafers to companies owned by Keylink International totaling 0.9% (1.1% in 2003) of the Company's sales. Also for 2004, 3.5% (4.6% in 2003) of the Company's sales were from discrete semiconductor products purchased from companies owned by Keylink International. In addition, Diodes-China and Diodes-Shanghai lease their manufacturing facilities from, and subcontract a portion of their manufacturing process (metal plating and environmental services) to, Keylink International. The Company also pays a consulting fee to Keylink International. Such transactions are on terms no less favorable to the Company than could be obtained from unaffiliated third parties. The Audit Committee of the Board of Directors has approved the contracts associated with the related party transactions. In October 2002, Silitek and Taiwan Lite-On merged with Lite-On Technology Corporation, a publicly traded company on the Taiwan Stock Exchange. Prior to this merger, Silitek was affiliated through common ownership and control with Taiwan Lite-On, and both companies were members of The Lite-On Group and publicly traded on the Taiwan Stock Exchange. Raymond Soong, who became a director and Chairman of the Board of the Company effective March 1993, is also the Chairman of the Boards of The Lite-On Group, Lite-On Technology Corporation, Diodes-China, Diodes-Shanghai, Diodes-Taiwan and Diodes-FabTech. Dr. Shing Mao, who is a director of the Company, retired in 2000 as Chairman of the Board of Lite-On Milpitas, a wholly-owned subsidiary of Taiwan Lite-On which merged with Lite-On Technology Corporation in 2002. Dr. Mao was also a director of LSC from 1989 to 2000, and since 1996, has been a director of FabTech. M.K. Lu, who has been a director of the Company since 1995, is also President of LSC and acting President of Actron Technology Corporation, both Lite-On Group companies. From 1983 to 1990, Mr. Lu was General Manager/Vice President of Silitek. Mr. Lu is also a director of Diodes-China, Diodes-Shanghai, and Diodes-FabTech. Michael Giordano, a director of the Company, is Senior Vice President-Investment Consulting at the investment-banking firm of UBS, Inc. Along with his son, James Giordano, Michael Giordano has, from time to time, assisted directors, executive officers, and employees of the Company in stock option exercises and subsequent stock sales of the Company's Common Stock, as well as provided investment management services. Mr. Giordano is also the pension 24

consultant for the Company's 401(k) plan, which is managed by UBS Fiduciary Trust. In addition, Mr. Giordano has, from time to time, provided investment management services for directors and officers of The Lite-On Group. All such services have been provided by UBS, Inc. at customary rates and terms. John M. Stich, a director of the Company, is also President and CEO of The Asian Network. In 2000 and 2001, Mr. Stich had received fees as a marketing consultant to the Company. In 2002, Mr. Stich ceased performing marketing consulting services for the Company. Dr. Keh-Shew Lu, a director of the Company, retired as Senior Vice President of TI and manager of Worldwide Mixed-Signal Products - Semiconductor Group in 2001. During 2002, Dr. Lu received fees as an engineering consultant to the Company. In 2003, Dr. Lu ceased performing engineering consulting services for the Company. Dr. Lu is also a director of Lite-On Technology Corporation. Mark A. King, the Company's Vice President of Sales and Marketing, has an approximate $100,000 investment in one of the Company's computer software vendors (a privately-held company). Mr. King's investment was made subsequent to the Company's purchase of the software, which is used for sales quotation and channel management, and has been approved by the Board of Directors. Fees paid to this software vendor in 2004, including annual software maintenance and consulting fees, were approximately $105,000. COMPLIANCE WITH SECTION 16(A) OF THE SECURITIES EXCHANGE ACT OF 1934 Under Section 16(a) of the Exchange Act, the Company's directors, executive officers and any persons holding ten percent or more of the Common Stock are required to report their ownership of Common Stock and any changes in that ownership to the SEC and to furnish the Company with copies of such reports. Specific due dates for these reports have been established and the Company is required to report any failure to file on a timely basis by such persons. Based solely upon a review of copies of reports filed with the SEC during the fiscal year ended December 31, 2004, all reporting persons filed reports on a timely basis except Messrs. Soong, Chen, Giordano, Mao, Stich, M.K. Lu, Keh-Shew Lu, Liu, King and Wertz who filed Form 4's on August 26, 2004 for stock options granted on July 14, 2004. To avoid the inadvertent failure of directors and executive officers to timely file these reports, the Company periodically advises such persons of their filing obligations. THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE ELECTION OF THE BOARD OF DIRECTORS' NOMINEES. PROPOSAL TWO - RATIFICATION OF THE APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The firm of Moss Adams LLP has been the Company's independent registered public accounting firm since 1993 and has been selected by the Board of Directors, upon recommendation of the Audit Committee to serve as its independent registered public accounting firm for the calendar year ending December 31, 2005. Professional services rendered by Moss Adams LLP for 2004 consisted of an audit of the Company's annual financial statements (including services incurred with rendering an opinion under Section 404 of Sarbanes-Oxley Act of 2002) and review of quarterly financial statements, consultation on interim financial statements, services related to filings with the SEC, meetings with the Company's Audit Committee and consultation on various matters relating to accounting and financial reporting. All professional services rendered by Moss Adams LLP during 2004 were furnished at customary rates and terms. Representatives of Moss Adams LLP are expected to be present at the Meeting. They will have the opportunity to make a statement, if they so desire, and respond to appropriate questions from Stockholders. 25

AUDIT FEES, TAX FEES, AND ALL OTHER FEES For the fiscal years ended December 31, 2003 and 2004, fees for services provided by Moss Adams LLP were approximately as follows: --------------------------------------------------------------- -------------- ------------- DESCRIPTION 2003 (1) 2004 --------------------------------------------------------------- -------------- ------------- AUDIT FEES, including fees for professional services necessary to perform an audit or review in accordance with the standards of the Public Company Accounting Oversight Board, including services rendered for the audit of the Company's financial statements (including services incurred with rendering an opinion under Section 404 of the Sarbanes-Oxley Act of 2002) included in the Annual Report on Form 10-K and review of financial statements included in the Quarterly Reports on Form 10-Q. $ 158,000 $ 426,000 --------------------------------------------------------------- -------------- ------------- AUDIT-RELATED FEES, including assurance related fees, accounting consultation and related services $ 31,000 $ 31,000 --------------------------------------------------------------- -------------- ------------- TAX FEES, professional services for income tax return preparation, tax advice and tax planning $ 74,000 $ 105,000 --------------------------------------------------------------- -------------- ------------- ALL OTHER FEES, not included in above $ 11,000 $ 19,000 --------------------------------------------------------------- -------------- ------------- TOTAL $ 274,000 $ 581,000 --------------------------------------------------------------- -------------- ------------- (1) - Prior year figures conform to current-year presentation The Audit Committee administers the Company's engagement of Moss Adams LLP and pre-approves all audit and permissible non-audit services on a case-by-case basis. In approving non-audit services, the Audit Committee considers whether the engagement could compromise the independence of Moss Adams LLP, and whether for reasons of efficiency or convenience it is in the best interest of the Company to engage its independent registered public accounting firm to perform the services. Moss Adams LLP has advised the Company that neither the firm, nor any member of the firm, has any financial interest, direct or indirect, in any capacity in the Company or its subsidiaries. The Audit Committee, in reliance on the independent registered public accounting firm, determined that the provision of these services is compatible with maintaining the independence of Moss Adams LLP. Prior to engagement, the Audit Committee pre-approves all independent registered public accounting firm services. The fees are budgeted and the Audit Committee requires the independent registered public accounting firm and management to report actual fees versus the budget periodically throughout the year by category of service. During the year, circumstances may arise when it may become necessary to engage the independent registered public accounting firm for additional services not contemplated in the original pre-approval categories. In those instances, the Audit Committee requires specific pre-approval before engaging the independent registered public accounting firm. The Audit Committee may delegate pre-approval authority to one or more of its members. The member to whom such authority is delegated must report, for informational purposes only, any pre-approval decisions to the Audit Committee at its next scheduled meeting. Although this appointment if not required to be submitted to a vote of Stockholders, the Audit Committee believes it is appropriate as a matter of policy to request that the Stockholders ratify the appointment. If the Stockholders do not ratify the appointment, which requires the affirmative vote of a majority of the outstanding shares of Common Stock present, in person or by proxy, and entitled to vote at the Meeting, the Board of Directors will consider the selection of another independent registered public accounting firm. THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 26

PROPOSALS OF STOCKHOLDERS AND STOCKHOLDER NOMINATIONS FOR 2006 ANNUAL MEETING Under certain circumstances, stockholders are entitled to present proposals at stockholder meetings. Currently, the 2006 annual meeting of stockholders is expected to be held on or about June 1, 2006. SEC rules provide that any stockholder proposal to be included in the proxy statement for the Company's 2006 annual meeting must be received by the Secretary of the Company at the Company's office at 3050 East Hillcrest Drive, Westlake Village, California 91362 prior to December 29, 2005, in a form that complies with applicable regulations.

SEC rules also govern a company's ability to use discretionary proxy authority with respect to stockholder proposals that were not submitted by the stockholders in time to be included in the proxy statement. In the event a stockholder proposal is not submitted to the Company prior to March 14, 2006, the proxies solicited by the Board of Directors for the 2006 annual meeting of stockholders will confer authority on the Proxyholders to vote the shares in accordance with their best judgment and discretion if the proposal is presented at the 2006 annual meeting of stockholders without any discussion of the proposal in the proxy statement for such meeting. Stockholders may nominate candidates for the Board of Directors at an annual meeting.

The requesting stockholder should provide sufficient biographical information about the proposed candidate to satisfy the requirements of the Securities and Exchange Commission for inclusion in the proxy statement and to permit the Nominating Committee to evaluate the proposed candidate in light of the criteria described under the caption "Nominating Procedures and Criteria." The request should also provide the full name, address and telephone number of the requesting stockholder and sufficient information to verify that the requesting shareholder is eligible to vote at the 2006 annual meeting.
