PROXY STATEMENT FOR 2006

ANNUAL MEETING OF STOCKHOLDERS

The enclosed proxy (“Proxy”) is solicited on behalf of the board of directors (the “Board of Directors”) of Integrated Silicon Solution, Inc. (the “Company”) for use at the annual meeting of stockholders (the “Annual Meeting”) to be held on Friday, February 3, 2006 at 3:30 p.m., local time, or at any adjournment thereof, for the purposes set forth herein and in the accompanying Notice of Annual Meeting. The Annual Meeting will be held at the Silicon Valley Capital Club, Fairmont Plaza, 50 West San Fernando, 17^th Floor, San Jose, California.

These proxy solicitation materials were mailed on or about January 3, 2006 to all stockholders of record at the close of business on December 9, 2005 (the “Record Date”). At the Record Date, 37,254,311 shares of the Company’s common stock, $.0001 par value per share, were issued and outstanding and no shares of the Company’s preferred stock, $.0001 par value per share, were issued and outstanding.

INFORMATION CONCERNING SOLICITATION AND VOTING

Your vote is important. Because many stockholders cannot attend the Annual Meeting in person, it is necessary that a large number be represented by proxy. Under Delaware law, stockholders may submit proxies electronically. Stockholders who hold their shares in a brokerage account may have the choice of voting over the Internet, by using a toll-free telephone number, or by completing a proxy card and mailing it in the postage-paid envelope provided. Please refer to the proxy card provided by your broker for details regarding the availability of electronic voting. Please also be aware that if you vote over the Internet, you may incur costs such as telephone and Internet access charges for which you will be responsible.

Revocability of Proxies

Any Proxy given pursuant to this solicitation may be revoked by the person giving such Proxy at any time before its use by delivering to the Secretary of the Company, at the address noted above, written notice of revocation or a duly executed proxy bearing a later date, or by attending the meeting and voting in person.

The method by which you vote will in no way limit your right to vote at the meeting if you later decide to attend in person. If your shares are held in the name of a bank, broker, or other holder of record, you must obtain a proxy, executed in your favor, from the holder of record to be able to vote at the Annual Meeting.

Voting and Solicitation

Proxies properly executed, duly returned to the Company and not revoked, will be voted in accordance with the instructions contained in such proxy. Where no instructions are given, such proxies will be voted “For” the election of each of the nominees for director, “For” the increase to the number of shares available for issuance under the Company’s 1998 Stock Plan, and “For” the ratification of the appointment of Ernst & Young LLP as the Company’s independent registered public accounting firm for the 2006 fiscal year, except as described below. If any matter not described in this proxy statement (the “Proxy Statement”) is properly presented for action at the meeting, the persons named in the enclosed proxy will have discretionary authority to vote according to their best judgment.

Each stockholder is entitled to one (1) vote for each share of common stock held by such stockholder on all matters presented at the Annual Meeting. The required quorum for the transaction of business at the Annual

1

Meeting is a majority of the votes eligible to be cast by holders of shares of common stock issued and outstanding as of the Record Date. Shares that are voted “FOR,” “AGAINST,” “WITHHELD” or “ABSTAIN” are treated as being present at the meeting for purposes of establishing a quorum and are also treated as shares entitled to vote at the Annual Meeting (the “Votes Cast”) with respect to such matter. Abstentions will have the same effect as a vote against a proposal, except with respect to the election of directors. Broker non-votes will be counted for purposes of determining the presence or absence of a quorum for the transaction of business, but such non-votes will not be counted for purposes of determining the number of Votes Cast with respect to the particular proposal on which a broker has expressly not voted. Thus, a broker non-vote will not affect the outcome of the voting on the proposals to be considered at the Annual Meeting.

Pursuant to regulations promulgated by the New York Stock Exchange (“NYSE”), brokers and other nominees that are NYSE member organizations are prohibited from voting in favor of proposals relating to equity compensation plans unless they receive specific instructions from the beneficial owner of the shares to vote on such matter. Therefore, for any of your shares held through a broker or other nominee that is a NYSE member organization, such shares will only be voted in favor of Proposal Two if you have provided specific voting instructions to your broker or other nominee to vote your shares in favor of such proposal.

The cost of soliciting proxies will be borne by the Company. The Company may also reimburse brokerage firms and other persons representing beneficial owners of shares for their expenses in forwarding solicitation materials to such beneficial owners. Certain of the Company’s directors, officers and employees, without additional compensation, may also solicit proxies personally or by telephone or telegram.

The Securities and Exchange Commission has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for proxy statements and annual reports with respect to two or more stockholders sharing the same address by delivering a single proxy statement addressed to those stockholders. Accordingly, a single Proxy Statement may be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. The Company will promptly deliver upon written request or oral request a separate copy of this proxy statement to any stockholder of a shared address to which a single copy of this document was delivered. If any stockholders of a shared address wish to receive a separate proxy statement, they may call the Company’s Corporate Secretary at (408) 969-6600 or write to Integrated Silicon Solution, Inc., 2231 Lawson Lane, Santa Clara, California 95054, Attention: Corporate Secretary. Other stockholders who have multiple accounts in their names or who share an address with other stockholders can authorize the Company to discontinue mailings of multiple proxy statements by calling or writing the Company’s Corporate Secretary. The Company maintains a web site on the Internet at www.issi.com. However, the web site, and the information contained therein, is not a part of this Proxy Statement.

Record Date

Stockholders of record at the close of business on December 9, 2005 are entitled to notice of the Annual Meeting and to vote upon matters presented at the Annual Meeting.

Deadline for Receipt of Stockholder Proposals

Stockholders of the Company may submit proper proposals for inclusion in the Company’s proxy statement and for consideration at the next annual meeting of stockholders by submitting their proposals in writing to the Secretary of the Company in a timely manner. In order to be included in the Company’s proxy materials for the annual meeting of stockholders to be held in the year 2007, stockholder proposals must be received by the Secretary of the Company no later than September 5, 2006, and must otherwise comply with the requirements of Rule 14a-8 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

In addition, the Company’s bylaws establish an advance notice procedure with regard to business brought before an annual meeting, including stockholder proposals not included in the Company’s proxy statement. For

2

nominations or other business to be properly brought before the 2007 annual meeting by a stockholder, such stockholder must provide written notice delivered to the Secretary of the Company one hundred twenty (120) days prior to the anniversary of the mailing of this Proxy Statement (i.e., September 5, 2006), which notice must contain specified information concerning the matters to be brought before such meeting and concerning the stockholder proposing such matters. In the event that no annual meeting was held in the previous year or the date of the annual meeting has been changed by more than thirty (30) days from the date contemplated at the time of the previous year’s proxy statement, for notice by the stockholder to be timely it must be received a reasonable time before the Company begins to print and mail its proxy materials.

The attached Proxy grants the proxy holders discretionary authority to vote on any matter raised at the Annual Meeting. If such a stockholder fails to comply with the foregoing notice provisions, proxy holders will be allowed to use their discretionary voting authority should the stockholder proposal come before the 2007 annual meeting.

A copy of the full text of the bylaw provisions governing the notice requirements set forth above may be obtained by writing to the Secretary of the Company. All notices of proposals and nominations by stockholders should be sent to Integrated Silicon Solution, Inc., 2231 Lawson Lane, Santa Clara, California 95054, Attention: Corporate Secretary.

Board of Directors Meetings and Committees

The Board of Directors held eight (8) meetings during fiscal 2005. The Board consists of Messrs. Lee, Fischer, Han, Ko, Tan, Tanigami, and Wooley. Mr. Han was CEO of ICSI and joined the Company’s Board in August 2005 in connection with the merger of the Company and ICSI upon the recommendation of Mr. Lee after discussion with the members of the Nominating Committee. The Board of Directors has determined that each of Messrs. Ko, Tan, Tanigami, and Wooley are “independent” as determined by the Nasdaq listing qualifications. The Board of Directors maintains four (4) standing committees: the Audit Committee, the Stock Committee, the Compensation Committee and the Nominating Committee.

Stockholders may communicate with members of the Board of Directors by mail addressed to an individual member of the Board, to the full Board, or to a particular committee of the Board, at the following address: 2231 Lawson Lane, Santa Clara, California, 95054.

Each director attended at least 75% of the aggregate of (i) the total number of meetings of the Board of Directors held during fiscal 2005 during such time as such person was a director and (ii) the total number of meetings held by all committees of the Board of Directors during fiscal 2005 during such time as such person was a director. All members of the Board of Directors who were then serving on the Board attended the 2005 Annual Meeting. The Company’s policy is that board members are expected to attend each Annual Meeting.

The Audit Committee. Mr. Tan serves as head of the Audit Committee along with members Messrs. Ko and Wooley. The Audit Committee held five (5) meetings during fiscal 2005. The Audit Committee is responsible for the appointment, compensation, retention and oversight of the Company’s independent registered public accounting firm; provides oversight and monitoring of Company management and the independent registered public accounting firm and their activities with respect to the Company’s financial reporting process and internal controls; provides the Board of Directors with the results of its monitoring and recommendations derived therefrom; and provides to the Board of Directors such additional information and materials as it may deem necessary to make the Board of Directors aware of significant financial matters that require the attention of the Board of Directors.

The Board of Directors believes that each member of the Audit Committee is an “independent director” as that term is defined by the Nasdaq listing standards and Rule 10A-3 of the Securities Exchange Act of 1934. The Board of Directors has determined that each of Mr. Ko and Mr. Tan is an audit committee financial expert, as defined by the Securities and Exchange Commission (the “SEC”) guidelines.

The Stock Committee. The Stock Committee consists of Messrs. Lee and Tan. The Stock Committee held seven (7) meetings during fiscal 2005. The Stock Committee has the authority to make routine stock option grants to non-executive officers of the Company.

The Compensation Committee. The Compensation Committee consists of Messrs. Tan and Tanigami, with Mr. Tan serving as head of the committee. The Compensation Committee held two (2) meetings during fiscal 2005. The Compensation Committee makes recommendations to the Board of Directors regarding the Company’s executive compensation policies and makes executive stock option grants.

The Nominating Committee. The Nominating Committee consists of Messrs. Ko, Tan, and Wooley, who are each deemed to be an “independent director” as that term is defined by the Nasdaq listing standards. The Board of Directors created the Nominating Committee in January 2004. The full text of the Nominating Committee Charter is published on the Company’s website at www.issi.com. The Nominating Committee held one (1) meeting in fiscal 2005. The Nominating Committee recommends nominees for election as directors to the Board of Directors. All members of the Nominating Committee are non-employee directors.

When considering a potential director candidate, the Nominating Committee looks for demonstrated character, judgment, relevant business, functional and industry experience, and a high degree of acumen. The

7

Nominating Committee’s process for identifying and evaluating nominees typically involves a series of internal discussions, review of information concerning candidates, and interviews with selected candidates. In general, candidates for nomination to the Board are suggested by directors or by employees. There are no differences in the manner in which the Nominating Committee evaluates nominees for director based on whether the nominee is recommended by a stockholder. The Company does not pay any third party to identify or assist in identifying or evaluating potential nominees.

The Nominating Committee will consider suggestions from stockholders regarding possible director candidates for election in 2007. Such suggestions, together with appropriate biographical information, should be submitted to the Company’s Corporate Secretary. See “Deadline for Receipt of Stockholder Proposals” for details regarding the procedures and timing for the submission of such suggestions. Each director nominated in this Proxy was recommended for election by the Nominating Committee and by the Board of Directors. The Board of Directors did not receive any notice of a Board of Directors nominee recommendation in connection with this Proxy Statement from any security holder.

Compensation of Directors

Non-employee directors receive a yearly retainer of $15,000 plus $3,000 for attendance at each regularly scheduled Board of Directors meeting and $1,000 for attendance at each telephone Board of Directors meeting. Non-employee directors receive $1,000 for attendance at board committee meetings in person or by telephone and the non-employee chairperson of a board committee receives an additional $1,000 payment per committee meeting attended in person (but not if attended by telephone). Non-employee directors are reimbursed for all reasonable expenses incurred by them in attending Board of Directors and Committee meetings. In addition, each non-employee director is eligible to participate in the Company’s 1995 Director Stock Option Plan (the “Director Plan”). Under the Director Plan, each non-employee director is automatically granted a nonstatutory option to purchase 10,000 shares of common stock on the date on which such person first becomes a non-employee director. In addition, each director who has been a non-employee director for at least six (6) months will automatically receive a nonstatutory option to purchase 2,500 shares of common stock upon such director’s annual reelection to the Board of Directors by the stockholders. Options granted under the Director Plan have a term of ten (10) years unless terminated sooner upon the termination of the optionee’s status as a director or otherwise pursuant to the Director Plan. The exercise price of each option granted under the Director Plan is equal to the fair market value of the common stock on the date of grant. Options granted under the Director Plan are subject to cumulative monthly vesting over a twelve (12) month period commencing at the date of grant.

The employee directors, Mr. Lee, Mr. Han and Mr. Fischer, receive no separate compensation to serve as directors of the Company. On February 4, 2005, Mr. Ko, Mr. Tan, Mr. Tanigami and Mr. Wooley were each granted an option under the Director Plan to purchase 2,500 shares of common stock at an exercise price of $6.55 per share. The options expire upon the earlier of ten (10) years from the date of grant unless terminated sooner upon termination of the optionee’s status as a director.

Compensation Committee Interlocks and Insider Participation

The Compensation Committee of the Board of Directors currently consists of Messrs. Tan and Tanigami, neither of whom has been or is an officer or an employee of the Company. No member of the Compensation Committee or executive officer of the Company has a relationship that would constitute an interlocking relationship with executive officers or directors of another entity. See “Certain Transactions” for details regarding Mr. Tan’s relationship with one of the Company’s suppliers.

Report of the Audit Committee*

The Audit Committee of the Board of Directors has furnished the following report:

The Board of Directors has adopted a written charter for the Audit Committee (the “Audit Committee Charter”). The Board of Directors has determined that each member of the Audit Committee is “independent,” as defined in the listing standards of Nasdaq.

The Company’s management is responsible for preparing financial statements and the Company’s independent registered public accounting firm is responsible for auditing the financial statements. The activities of the Audit Committee are in no way designed to supersede or alter those traditional responsibilities. The Audit Committee’s role does not provide any special assurances with regard to the Company’s financial statements, nor does it involve a professional evaluation of the quality of the audits performed by the independent registered public accounting firm.

The Audit Committee has reviewed and discussed the audited financial statements for fiscal 2005 with the Company’s management.

The Audit Committee has discussed with the independent registered public accounting firm, Ernst & Young LLP, the matters required to be discussed by Statement of Auditing Standards No. 61, Communication with Audit Committees.

The Audit Committee has received the written disclosures and the letter from the independent registered public accounting firm required by Independence Standards Board Standard No. 1, Independence Discussions with Audit Committees, has considered the compatibility of receiving non-audit services from the independent registered public accounting firm with maintaining the independent registered public accounting firm’s independence, and has discussed with the independent registered public accounting firm the independent registered public accounting firm’s independence.

Based on the review and discussions referred to above, the Audit Committee recommended to the Board of Directors that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2005.

Report of the Compensation Committee of the Board of Directors*

The members of the Compensation Committee of the Board of Directors are Messrs. Tan and Tanigami. All such members are non-employee directors. The Compensation Committee reviews compensation levels of the Company’s executive officers, recommends to the Board of Directors for approval the salaries and other compensation paid to such executives, and approves stock option grants to executive officers.

* The material in this report is not “soliciting material,” is not deemed “filed” with the SEC, and is not to be incorporated by reference into any filing of the Company under the Securities Act of 1933, as amended, or the Exchange Act, whether made before or after the date hereof and irrespective of any general incorporation language contained in such filing.

Compensation Philosophy. The Company’s executive pay programs are designed to attract and retain executives who will contribute to the Company’s long-term success, to reward executives for achieving both short and long-term strategic Company goals, to link executive and stockholder interests through equity based plans, and to provide a compensation package that recognizes individual contributions and Company performance. A meaningful portion of each executive’s total compensation is intended to be variable and to relate to and be contingent upon Company performance and upon individual performance. Corporate performance is measured by relevant financial results and the success of the management team in non-financial areas, such as strategic business decisions, operational performance and management objectives. The Company’s compensation philosophy is that cash compensation must be competitive with other semiconductor companies of comparable size in order to help motivate and retain existing staff and provide a strong incentive to achieve specific Company goals. The Company believes that the use of stock options as a long-term incentive links the interests of the employees to that of the stockholders and motivates key employees to remain with the Company to contribute to the Company’s long-term success. When the Compensation Committee grants long-term equity-based incentives, the number of options or shares granted to or owned by the executive, the value of such options or shares and competitive compensation practices of comparable companies are taken into consideration in determining the size and structure of the award.

Components of Executive Compensation. The two key components of the Company’s executive officer compensation program in fiscal 2005 were base salary and long-term incentives, represented by the Company’s stock option program. No bonuses were paid in fiscal 2005. In determining the total compensation for each of the Company’s executive officers, the Committee evaluates corporate performance, principally revenue and operating profit goals; such executive officer’s individual performance; compensation paid to executive officers of companies of comparable size within the semiconductor industry; and compensation paid to other executive officers of the Company. Base salary is set for each executive commensurate with that person’s level of responsibility, within the parameters of companies of comparable size within the semiconductor industry, and existing industry conditions. For fiscal 2005, Mr. Lee’s base salary was initially set at $300,000 and Mr. Fischer’s base salary was initially set at $240,000, which were the same salaries such officers had in fiscal 2004. In August 2005, in connection with the Company’s acquisition of ICSI, Mr. Lee’s base salary was set at $280,000, Mr. Fischer’s base salary was set at $240,000, and the cash compensation including base salary and costs of relocation and maintaining dual residences for Messrs. K.Y. Han, Hu and Chang-Chaio Han was set at $240,000. For all of 2005, Mr. Lee took a voluntary salary reduction to $240,000.

Stock options are generally granted when an executive joins the Company, and additional options may be granted from time-to-time thereafter. The options granted to each executive generally vest over a four (4) year period. In addition to receiving stock option grants, executives are also eligible to participate in the Company’s employee stock purchase plan.

Other elements of executive compensation include participation in the Company’s 401(k) plan, Company-wide medical and dental benefits and a non-qualified deferred compensation program. The Company does not match contributions under the 401(k) plan at this time.

Mr. Lee receives no additional material compensation or benefits not provided to all executives. Mr. Lee’s total compensation consists of base salary and employee stock options. In determining Mr. Lee’s compensation, the Committee evaluates:

• corporate performance, principally revenue and operating profit goals;

• his individual performance;

• compensation paid to other executive officers of the Company; and

• compensation paid to chief executive officers of comparable companies.

For fiscal 2005, none of the Company’s executive officers, including Mr. Lee, received a salary increase and no bonuses were paid.

10

The Compensation Committee has considered the potential impact of Section 162(m) of the Internal Revenue Code of 1986, as amended, and the regulations thereunder (the “Section”). The Section disallows a tax deduction for any publicly held corporation for individual compensation exceeding $1 million in any taxable year for any of the Named Executive Officers, unless such compensation is performance based. Since the cash compensation of each of the Named Executive Officers is below the $1 million threshold and the Compensation Committee believes that any options granted under the Company’s stock option plan would meet the requirements of being performance based, the Compensation Committee believes that the Section will not reduce the tax deduction available to the Company. The Company’s policy is to qualify, to the extent reasonable, its executive officers’ compensation for deductibility under applicable tax laws. However, the Compensation Committee believes that its primary responsibility is to provide a compensation program that will attract, retain and reward the executive talent necessary to the Company’s success. Consequently, the Compensation Committee recognizes that the loss of a tax deduction could be necessary in some circumstances.

PROPOSAL TWO:

APPROVAL OF AMENDMENT TO 1998 STOCK PLAN

The Company’s Board of Directors and stockholders previously adopted and approved the Company’s 1998 Stock Plan (the “Stock Plan”). The Company is asking its stockholders to approve a proposed amendment to the Stock Plan to increase the number of shares of Common Stock reserved for issuance thereunder by 1,000,000 shares. Currently, the maximum aggregate number of shares that may be optioned and sold under the Stock Plan is (a) 1,000,000 shares, plus (b) any shares which have been reserved but not issued under the Company’s 1989 Stock Plan, and (c) any shares returned to the Company’s 1989 Stock Plan as a result of the termination of options under the 1989 Stock Plan. As of the Record Date, prior to the proposed amendment, 1,560,771 shares were available for future issuance under the Stock Plan. In October 2005, the Board of Directors approved the addition of shares to the Stock Plan, subject to stockholder approval.

The Board believes that the amendment will enable the Company to continue its policy of widespread employee stock ownership as a means to motivate high levels of performance and to recognize key employee accomplishments.

The following summary of the principal terms of the Stock Plan is qualified in its entirety by reference to the full text of the plan which is attached hereto as Appendix A.

General. The Stock Plan was adopted by the Board of Directors in October 1998 and approved by the Company’s stockholders in February 1999. The Stock Plan authorizes the Board, or one or more committees which the Board may appoint from among its members (the “Committee”), to grant stock options or stock purchase rights (“SPRs”). Options granted under the Stock Plan may be either Incentive Stock Option (“ISOs”) as defined in Section 422 of the Code, or Nonstatutory Stock Options (“NSOs”), as determined by the Board or the Committee. The shares reserved under the Stock Plan may be authorized, but unissued, or reacquired Common Stock.

Purpose. The general purpose of the Stock Plan is to attract and retain the best available personnel for positions of substantial responsibility, to provide additional incentive to employees, directors, and consultants and to promote the success of the Company’s business.

Administration. The Stock Plan may be administered by the Board or the Committee. Subject to the other provisions of the Stock Plan, the Board or the Committee has the authority to: (i) interpret the Stock Plan and

11

apply its provisions; (ii) prescribe, amend or rescind rules and regulations relating to the Stock Plan; (iii) select the persons to whom options and SPRs are to be granted; (iv) determine the number of shares to be made subject to each option and SPR; (v) determine whether and to what extent options and SPRs are to be granted; and (vi) prescribe the terms and conditions of each option and SPR (including the exercise price, whether an option will be classified as an ISO or a NSO and the provisions of the stock option or stock purchase agreement to be entered into between the Company and the grantee). All decisions, interpretations and other actions of the Board or Committee shall be final and binding on all holders of options and SPRs and on all persons deriving their rights therefrom.

Eligibility. The Stock Plan provides that options and SPRs may be granted to the Company’s employees, directors, and consultants (as such terms are defined in the Stock Plan). As of December 9, 2005, approximately 389 of the Company’s employees and consultants were eligible to participate in the Stock Plan. ISOs may be granted only to employees. Any optionee who owns more than 10% of the combined voting power of all classes of outstanding stock of the Company or any parent or subsidiary is not eligible for the grant of an ISO unless the exercise price of the option is at least 110% of the fair market value of the Common Stock on the date of grant.

The Stock Plan provides that no employee shall be granted, in any fiscal year of the Company, options to purchase more than 250,000 shares of Common Stock. In connection with an employee’s initial employment, the employee may be granted options to purchase up to an additional 250,000 shares of Common Stock.

Terms and Conditions of Options. Each option granted under the Stock Plan is evidenced by a written stock option agreement between the optionee and the Company and is subject to the following terms and conditions:

(a) Exercise of the Option. Each option will be exercisable according to the terms of the Stock Plan and each stock option agreement. An option will be deemed exercised when the Company receives: (i) written or electronic notice of exercise (in accordance with the stock option agreement), and (ii) full payment for the shares with respect to which the option is exercised. Until the shares of Common Stock are issued, no right to vote or receive dividends or any other rights as a stockholder will exist with respect to the optioned stock, notwithstanding the exercise of the option. The Company will issue such shares promptly after the option is exercised.

(b) Exercise Price. The Board determines the exercise price of options to purchase shares of Common Stock at the time the options are granted. However, excluding options issued to 10% stockholders, the exercise price under an ISO must not be less than 100% of the fair market value of the Common Stock on the date the option is granted. Generally, the fair market value shall be the closing sales price for such stock (or the closing bid, if no sales were reported) as quoted on the Nasdaq National Market on the last market trading day prior to the date of determination.

(c) Form of Consideration. The means of payment for shares issued upon exercise of an option is specified in each stock option agreement and generally may be made by cash, check, promissory note, other shares of Common Stock of the Company owned by the optionee, delivery of an exercise notice together with irrevocable instructions to a broker to deliver the exercise price to the Company from the sale or loan proceeds, reduction in the amount of any Company liability to the optionee, or by a combination thereof, or such other consideration and method of payment for the issuance of shares to the extent permitted by applicable laws.

(d) Term of Options. Each stock option agreement will specify the term of the option and the date when the option is to become exercisable. However, in no event shall an option granted under the Stock Plan be exercised more than ten (10) years after the date of grant. Moreover, in the case of an ISO granted to a 10% stockholder, the term of the option shall be for no more than five (5) years from the date of grant. No options may be exercised by any person after the expiration of its term.

(e) Termination of Continuous Status. In the event of termination of an optionee’s continuous status as an employee, director, or consultant with the Company (as the case may be), such optionee may, but only within

12

three (3) months following the optionee’s termination (or within such other period of time as is determined by the Board) after the date of such termination (but in no event later than the expiration date of the term of such option as set forth in the option agreement), exercise his option to the extent that the optionee was entitled to exercise it at the date of such termination. To the extent that the optionee was not entitled to exercise the option at the date of such termination, or if the optionee does not exercise such option to the extent so entitled within the time specified herein, the option shall terminate.

(f) Disability. In the event of termination of an optionee’s continuous status as an employee, director, or consultant as a result of his total and permanent disability (as defined in Section 22(e)(3) of the Code), the optionee may, but only within twelve (12) months (or within such other period of time as is determined by the Board) from the date of such termination (but in no event later than the expiration date of the term of such option as set forth in the option agreement), exercise the option to the extent otherwise entitled to exercise it at the date of such termination. To the extent that the optionee was not entitled to exercise the option at the date of termination, or if the optionee does not exercise such option to the extent so entitled within the time specified herein, the option shall terminate.

(g) Death. In the event of the death of an optionee while the optionee is an employee, director, or consultant, the option may be exercised at any time within twelve (12) months following the date of death (but in no event later than the expiration date of the term of such option as set forth in the option agreement), by the optionee’s estate or by a person who acquired the right to exercise the option by bequest or inheritance, but only to the extent the optionee was entitled to exercise the option at the date of death. To the extent that the optionee was not entitled to exercise the option at the date of death, or if the optionee’s estate does not exercise such option to the extent so entitled within the time specified herein, the option shall terminate.

(h) Nontransferability of Options. Unless determined otherwise by the administrator, an option 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 optionee, only by the optionee.

(i) Value Limitation. If the aggregate fair market value of all shares of Common Stock subject to an optionee’s ISOs which are exercisable for the first time during any calendar year under all plans of the Company or any parent or subsidiary exceeds $100,000, such excess options shall be treated as NSOs.

(j) Buyout Provisions. The Board or Committee may at any time offer to buy out for a payment in cash or shares, an option previously granted, based on such terms and conditions as the Board or Committee shall establish and communicate to the optionee at the time that such offer is made.

Stock Purchase Rights. The Stock Plan permits the Company to grant rights to purchase Common Stock either alone or in combination with other awards granted under the Stock Plan or in combination with cash awards made outside of the Stock Plan.

(a) Term of Stock Purchase Rights. After the Board or Committee determines that it will offer SPRs under the Stock Plan, it shall advise the offeree in writing or electronically, by means of a notice of grant, of the terms, conditions and restrictions related to the offer, including the number of shares that the offeree shall be entitled to purchase, the price to be paid and the time within which the offeree must accept such offer. The offer shall be accepted by execution of a restricted stock purchase agreement in the form determined by the Board or Committee.

(b) Repurchase Option. Unless the Board or Committee determines otherwise, the restricted stock purchase agreement shall grant the Company a repurchase option exercisable upon the voluntary or involuntary termination of the purchaser’s service with the Company for any reason (including death or disability). The purchase price for shares repurchased pursuant to the restricted stock purchase agreement shall be the original price paid by the purchaser and may be paid by cancellation of any indebtedness of the purchaser to the Company. The repurchase option shall lapse at such rate as the Board or Committee may determine.

13

(c) Nontransferability of Stock Purchase Rights. Unless determined otherwise by the Board or Committee, a SPR 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 offeree, only by the offeree.

Adjustments upon Changes in Capitalization or Merger. Subject to any required action by the stockholders of the Company, the number of shares of Common Stock covered by each outstanding option or SPR, and the number of shares of Common Stock which have been authorized for issuance under the Stock Plan but as to which no options or SPRs have yet been granted or which have been returned to the Stock Plan upon cancellation or expiration of an option or SPR, as well as the price per share of Common Stock covered by each such outstanding option or SPR, shall be proportionately adjusted for an any increase or decrease in the number of issued shares of Common Stock resulting from a stock split, reverse stock split, stock dividend, combination or reclassification of the Common Stock, or any other increase or decrease in the number of issued shares of Common Stock effected without receipt of consideration by the Company; 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 Board, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, 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 thereof shall be made with respect to, the number or price of shares of Common Stock subject to an option or SPR.

In the event of the proposed dissolution or liquidation of the Company, the Board or Committee shall notify the optionee, as soon as practicable prior to the effective date of such proposed action. To the extent it has not been previously exercised, the option or SPR will terminate immediately prior to the consummation of such proposed action.

In the event of a merger of the Company with or into another corporation, or the sale of substantially all of the Company’s assets, each outstanding option or SPR shall be assumed or an equivalent option or right shall be substituted by such successor corporation or a parent or subsidiary of such successor corporation. In the event that such successor corporation does not agree to assume the option or SPR or to substitute an equivalent option, the Board shall, in lieu of such assumption or substitution, provide for the optionee to have the right to exercise the option or SPR as to all of the optioned stock, including shares as to which the option would not otherwise be exercisable. If the Board makes an option or SPR fully exercisable in lieu of assumption or substitution in the event of a merger, the Board shall notify the optionee that the option or SPR shall be fully exercisable for a period of fifteen (15) days from the date of such notice, and the option or SPR will terminate upon the expiration of such period.

Amendments, Suspensions and Termination of the Stock Plan. The Board may amend, alter, suspend or discontinue the Stock Plan at any time, but no amendment, alteration, suspension or discontinuation shall be made which would impair the rights of any optionee unless mutually agreed otherwise between the optionee and the Board in a writing signed by the optionee and the Company. The Company shall obtain stockholder approval for any Stock Plan amendment to the extent necessary to comply with applicable laws. In any event, the Stock Plan will terminate automatically in 2008.

Federal Tax Information for Stock Plan. Options granted under the Stock Plan may be either ISOs or NSOs.

An optionee who is granted an ISO will not recognize taxable income either at the time the option is granted or upon its exercise, although the exercise may subject the optionee to the alternative minimum tax. Upon the sale or exchange of the shares more than two (2) years after grant of the option and one (1) year after exercise of the option, any gain or loss will be treated as long-term capital gain or loss. If these holding periods are not satisfied, the optionee will recognize ordinary income at the time of sale or exchange equal to the difference between the exercise price and the lower of (i) the fair market value of the shares on the date of exercise and

14

(ii) the sale price of the shares. The Company will be entitled to a deduction in the same amount as the ordinary income recognized by the optionee. Any gain or loss recognized on such a premature disposition of the shares in excess of the amount treated as ordinary income will be characterized as long-term or short-term capital gain or loss, depending on the holding period.

All options which do not qualify as ISOs are referred to as NSOs. An optionee will not recognize any taxable income at the time he or she is granted an NSO. However, upon its exercise, the optionee will recognize ordinary income generally measured as the excess of the then fair market value of the shares purchased over the purchase price. Any ordinary income recognized in connection with an option exercise by an optionee who is also an employee of the Company will be subject to tax withholding by the Company. Upon resale of such shares by the optionee, any difference between the sales price and the optionee’s purchase price, to the extent not recognized as ordinary income as described above, will be treated as long-term or short-term capital gain or loss, depending on the holding period. The Company will be entitled to a tax deduction in the same amount as the ordinary income recognized by the optionee with respect to shares acquired upon exercise of an NSO.

Stock purchase rights will generally be taxed in the same manner as nonstatutory stock options. However, restricted stock is generally purchased upon the exercise of a stock purchase right. At the time of purchase, restricted stock is subject to a “substantial risk of forfeiture” within the meaning of Section 83 of the Code. As a result, the purchaser will not recognize ordinary income at the time of purchase. Instead, the purchaser will recognize ordinary income on the dates when a stock ceases to be subject to a substantial risk of forfeiture. The stock will generally cease to be subject to a substantial risk of forfeiture when it is no longer subject to the Company’s right to repurchase the stock upon the purchaser’s termination of employment with the Company. At such times, the purchaser will recognize ordinary income measured as the difference between the purchase price and the fair market value of the stock on the date the stock is no longer subject to a substantial risk of forfeiture.

The purchaser may accelerate to the date of purchase his or her recognition of ordinary income, if any, and the beginning of any capital gain holding period by timely filing an election pursuant to Section 83(b) of the Code. In such event, the ordinary income recognized, if any, is measured as the difference between the purchase price and the fair market value of the stock on the date of purchase, and the capital gain holding period commences on such date. The ordinary income recognized by a purchaser who is an employee will be subject to tax withholding by the Company.

THE FOREGOING IS ONLY A SUMMARY OF THE EFFECT OF FEDERAL INCOME TAXATION UPON THE STOCK PLAN PARTICIPANT AND THE COMPANY WITH RESPECT TO THE GRANT AND EXERCISE OF OPTIONS AND THE GRANT OF STOCK PURCHASE RIGHTS UNDER THE STOCK PLAN, DOES NOT PURPORT TO BE COMPLETE, AND DOES NOT DISCUSS THE TAX CONSEQUENCES OF THE STOCK PLAN PARTICIPANT’S DEATH OR THE INCOME TAX LAWS OF ANY MUNICIPALITY, STATE OR FOREIGN COUNTRY IN WHICH THE STOCK PLAN PARTICIPANT MAY RESIDE.

Stock Plan Benefits. The Company is unable to predict the amount of benefits that will be received by or allocated to any particular participant under the Stock Plan. The following table sets forth the dollar amount and the number of shares granted under the Stock Plan during the last fiscal year to (i) each of the Company’s Named Executive Officers, (ii) all executive officers as a group, (iii) all non-employee directors as a group and (iv) all employees other than executive officers as a group.

This plan was approved by stockholders effective February 1995 and was amended by the stockholders on February 6, 2002, on February 27, 2004, and on February 4, 2005.

Equity compensation plan not approved by security holders.

At September 30, 2005, the Company’s 1996 Stock Option Plan was not approved by the Company’s stockholders. On October 18, 1996, the Company’s Board of Directors approved the 1996 Stock Option Plan that provides for the grant of non-statutory stock options to non-executive employees and consultants. At September 30, 2005, options to purchase 2,257,000 shares of the Company’s common stock remained available for future issuance under this plan and options to purchase 4,742,000 shares of the Company’s common stock were outstanding with a weighted average exercise price of $7.74 and grant prices ranging from $2.35 to $18.56. Under the terms of the plan, the exercise price and exercise period of stock option grants is determined by the Board of Directors or the Stock Committee of the Board on the date of grant. Generally, the stock options vest ratably over a four (4) year period. The options expire upon the earlier of ten (10) years from the date of grant or thirty (30) days following termination of employment or consultancy, unless specified otherwise in the option agreement. In the event of certain changes in control of the Company, the 1996 Stock Option Plan requires that each outstanding option be assumed or an equivalent option substituted by the successor corporation. However, if such successor refuses to assume the then outstanding options, the 1996 Stock Option Plan provides for the full acceleration of the exercisability of all outstanding options.

(vi) to reduce the exercise price of any Option or Stock Purchase Right to the then current Fair Market Value if the Fair Market Value of the Common Stock covered by such Option or Stock Purchase Right shall have declined since the date the Option or Stock Purchase Right was granted;

(vii) to institute an Option Exchange Program;

(viii) to construe and interpret the terms of the Plan and awards granted pursuant to the Plan;

(xi) to allow Optionees to satisfy withholding tax obligations by electing to have the Company withhold from the Shares to be issued upon exercise of an Option or Stock Purchase Right that number of Shares having a Fair Market Value equal to the amount required to be withheld. The Fair Market Value of the Shares to be withheld shall be determined on the date that the amount of tax to be withheld is to be determined. All elections by an Optionee to have Shares withheld for this purpose shall be made in such form and under such conditions as the Administrator may deem necessary or advisable;

(xii) to authorize any person to execute on behalf of the Company any instrument required to effect the grant of an Option or Stock Purchase Right previously granted by the Administrator;

5. Eligibility. Nonstatutory Stock Options and Stock Purchase Rights may be granted to Service Providers. Incentive Stock Options may be granted only to Employees.

6. Limitations.

(a) Each Option shall be designated in the Option Agreement as either an Incentive Stock Option or a Nonstatutory Stock Option. However, notwithstanding such designation, to the extent that the aggregate Fair Market Value of the Shares with respect to which Incentive Stock Options are exercisable for the first time by the Optionee during any calendar year (under all plans of the Company and any Parent or Subsidiary) exceeds $100,000, such Options shall be treated as Nonstatutory Stock Options. For purposes of this Section 6(a), Incentive Stock Options shall be taken into account in the order in which they were granted. The Fair Market Value of the Shares shall be determined as of the time the Option with respect to such Shares is granted.

A-4

(b) Neither the Plan nor any Option or Stock Purchase Right shall confer upon an Optionee any right with respect to continuing the Optionee’s relationship as a Service Provider with the Company, nor shall they interfere in any way with the Optionee’s right or the Company’s right to terminate such relationship at any time, with or without cause.

(c) The following limitations shall apply to grants of Options:

(i) No Service Provider shall be granted, in any fiscal year of the Company, Options to purchase more than 250,000 Shares.

(ii) In connection with his or her initial service, a Service Provider may be granted Options to purchase up to an additional 250,000 Shares which shall not count against the limit set forth in subsection (i) above.

(iii) The foregoing limitations shall be adjusted proportionately in connection with any change in the Company’s capitalization as described in Section 13.

(iv) If an Option is cancelled in the same fiscal year of the Company in which it was granted (other than in connection with a transaction described in Section 13), the cancelled Option will be counted against the limits set forth in subsections (i) and (ii) above. For this purpose, if the exercise price of an Option is reduced, the transaction will be treated as a cancellation of the Option and the grant of a new Option.

7. Term of Plan. Subject to Section 19 of the Plan, the Plan shall become effective upon its adoption by the Board. It shall continue in effect for a term of ten (10) years unless terminated earlier under Section 15 of the Plan.

8. Term of Option. The term of each Option shall be stated in the Option Agreement. In the case of an Incentive Stock Option, the term shall be ten (10) years from the date of grant or such shorter term as may be provided in the Option Agreement. Moreover, in the case of an Incentive Stock Option granted to an Optionee who, at the time the Incentive Stock Option is granted, owns stock representing more than ten percent (10%) of the total combined 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 or such shorter term as may be provided in the Option Agreement.

9. Option Exercise Price and Consideration.

(a) Exercise Price. The per share exercise price for the Shares to be issued pursuant to exercise of an Option shall be determined by the Administrator, subject to the following:

(i) In the case of an Incentive Stock Option

(1) granted to an Employee who, at the time the Incentive Stock 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 per Share exercise price shall be no less than 110% of the Fair Market Value per Share on the date of grant.

(2) granted to any Employee other than an Employee described in paragraph (A) immediately above, the per Share exercise price shall be no less than 100% of the Fair Market Value per Share on the date of grant.

(ii) In the case of a Nonstatutory Stock Option, the per Share exercise price shall be determined by the Administrator. In the case of a Nonstatutory Stock Option intended to qualify as “performance-based compensation” within the meaning of Section 162(m) of the Code, the per Share exercise price shall be no less than 100% of the Fair Market Value per Share on the date of grant.

(iii) Notwithstanding the foregoing, Options may be granted with a per Share exercise price of less than 100% of the Fair Market Value per Share on the date of grant pursuant to a merger or other corporate transaction.

A-5

(b) Waiting Period and Exercise Dates. At the time an Option is granted, the Administrator shall fix the period within which the Option may be exercised and shall determine any conditions which must be satisfied before the Option may be exercised.

(c) Form of Consideration. The Administrator shall determine the acceptable form of consideration for exercising an Option, including the method of payment.

(v) consideration received by the Company under a cashless exercise program implemented by the Company in connection with the Plan;

(viii) such other consideration and method of payment for the issuance of Shares to the extent permitted by Applicable Laws.

10. Exercise of Option.

(a) Procedure for Exercise; Rights as a Shareholder. Any Option granted hereunder shall be exercisable according to the terms of the Plan and at such times and under such conditions as determined by the Administrator and set forth in the Option Agreement. Unless the Administrator provides otherwise, vesting of Options granted hereunder shall be tolled during any unpaid leave of absence. An Option may not be exercised for a fraction of a Share.

An Option shall be deemed exercised when the Company receives: (i) written or electronic notice of exercise (in accordance with the Option Agreement) from the person entitled to exercise the Option, and (ii) full payment for the Shares with respect to which the Option is exercised. Full payment may consist of any consideration and method of payment authorized by the Administrator and permitted by the Option Agreement and the Plan. Shares issued upon exercise of an Option shall be issued in the name of the Optionee or, if requested by the Optionee, in the name of the Optionee and his or her spouse. Until the Shares are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a shareholder shall exist with respect to the Optioned Stock, notwithstanding the exercise of the Option. The Company shall issue (or cause to be issued) such Shares promptly after the Option is exercised. No adjustment will be made for a dividend or other right for which the record date is prior to the date the Shares are issued, except as provided in Section 13 of the Plan

Exercising an Option in any manner shall decrease the number of Shares thereafter available, both for purposes of the Plan and for sale under the Option, by the number of Shares as to which the Option is exercised.

(b) Termination of Relationship as a Service Provider. If an Optionee ceases to be a Service Provider, other than upon the Optionee’s death or Disability, the Optionee may exercise his or her Option within such period of

A-6

time as is specified in the Option Agreement to the extent that the Option is vested on the date of termination (but in no event later than the expiration of the term of such Option as set forth in the Option Agreement). In the absence of a specified time in the Option Agreement, the Option shall remain exercisable for three (3) months following the Optionee’s termination. If, on the date of termination, the Optionee is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option shall revert to the Plan. If, after termination, the Optionee does not exercise his or her Option within the time specified by the Administrator, the Option shall terminate, and the Shares covered by such Option shall revert to the Plan.

(c) Disability of Optionee. If an Optionee ceases to be a Service Provider as a result of the Optionee’s Disability, the Optionee may exercise his or her Option within such period of time as is specified in the Option Agreement to the extent the Option is vested on the date of termination (but in no event later than the expiration of the term of such Option as set forth in the Option Agreement). In the absence of a specified time in the Option Agreement, the Option shall remain exercisable for twelve (12) months following the Optionee’s termination. If, on the date of termination, the Optionee is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option shall revert to the Plan. If, after termination, the Optionee does not exercise his or her Option within the time specified herein, the Option shall terminate, and the Shares covered by such Option shall revert to the Plan.

(d) Death of Optionee. If an Optionee dies while a Service Provider, the Option may be exercised within such period of time as is specified in the Option Agreement (but in no event later than the expiration of the term of such Option as set forth in the Notice of Grant), by the Optionee’s estate or by a person who acquires the right to exercise the Option by bequest or inheritance, but only to the extent that the Option is vested on the date of death. In the absence of a specified time in the Option Agreement, the Option shall remain exercisable for twelve (12) months following the Optionee’s termination. If, at the time of death, the Optionee is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option shall immediately revert to the Plan. The Option may be exercised by the executor or administrator of the Optionee’s estate or, if none, by the person(s) entitled to exercise the Option under the Optionee’s will or the laws of descent or distribution. If the Option is not so exercised within the time specified herein, the Option shall terminate, and the Shares covered by such Option shall revert to the Plan.

(e) Buyout Provisions. The Administrator may at any time offer to buy out for a payment in cash or Shares an Option previously granted based on such terms and conditions as the Administrator shall establish and communicate to the Optionee at the time that such offer is made.

11. Stock Purchase Rights.

(a) Rights to Purchase. Stock Purchase Rights may be issued either alone, in addition to, or in tandem with other awards granted under the Plan and/or cash awards made outside of the Plan. After the Administrator determines that it will offer Stock Purchase Rights under the Plan, it shall advise the offeree in writing or electronically, by means of a Notice of Grant, of the terms, conditions and restrictions related to the offer, including the number of Shares that the offeree shall be entitled to purchase, the price to be paid, and the time within which the offeree must accept such offer. The offer shall be accepted by execution of a Restricted Stock Purchase Agreement in the form determined by the Administrator.

(b) Repurchase Option. Unless the Administrator determines otherwise, the Restricted Stock Purchase Agreement shall grant the Company a repurchase option exercisable upon the voluntary or involuntary termination of the purchaser’s service with the Company for any reason (including death or Disability). The purchase price for Shares repurchased pursuant to the Restricted Stock Purchase Agreement shall be the original price paid by the purchaser and may be paid by cancellation of any indebtedness of the purchaser to the Company. The repurchase option shall lapse at a rate determined by the Administrator.

(c) Other Provisions. The Restricted Stock Purchase Agreement shall contain such other terms, provisions and conditions not inconsistent with the Plan as may be determined by the Administrator in its sole discretion.

A-7

(d) Rights as a Shareholder. Once the Stock Purchase Right is exercised, the purchaser shall have the rights equivalent to those of a shareholder, and shall be a shareholder when his or her purchase is entered upon the records of the duly authorized transfer agent of the Company. No adjustment will be made for a dividend or other right for which the record date is prior to the date the Stock Purchase Right is exercised, except as provided in Section 13 of the Plan.

12. Non-Transferability of Options and Stock Purchase Rights. Unless determined otherwise by the Administrator, an Option or Stock Purchase Right 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 Optionee, only by the Optionee. If the Administrator makes an Option or Stock Purchase Right transferable, such Option or Stock Purchase Right shall contain such additional terms and conditions as the Administrator deems appropriate.

13. Adjustments Upon Changes in Capitalization, Dissolution, Merger or Asset Sale.

(a) Changes in Capitalization. Subject to any required action by the shareholders of the Company, the number of shares of Common Stock covered by each outstanding Option and Stock Purchase Right, and the number of shares of Common Stock which have been authorized for issuance under the Plan but as to which no Options or Stock Purchase Rights have yet been granted or which have been returned to the Plan upon cancellation or expiration of an Option or Stock Purchase Right, as well as the price per share of Common Stock covered by each such outstanding Option or Stock Purchase Right, shall be proportionately adjusted for any increase or decrease in the number of issued shares of Common Stock resulting from a stock split, reverse stock split, stock dividend, combination or reclassification of the Common Stock, or any other increase or decrease in the number of issued shares of Common Stock effected without receipt of consideration by the Company; 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 Board, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, 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 thereof shall be made with respect to, the number or price of shares of Common Stock subject to an Option or Stock Purchase Right.

(b) Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, the Administrator shall notify each Optionee as soon as practicable prior to the effective date of such proposed transaction. The Administrator in its discretion may provide for an Optionee to have the right to exercise his or her Option until ten (10) days prior to such transaction as to all of the Optioned Stock covered thereby, including Shares as to which the Option would not otherwise be exercisable. In addition, the Administrator may provide that any Company repurchase option applicable to any Shares purchased upon exercise of an Option or Stock Purchase Right shall lapse as to all such Shares, provided the proposed dissolution or liquidation takes place at the time and in the manner contemplated. To the extent it has not been previously exercised, an Option or Stock Purchase Right will terminate immediately prior to the consummation of such proposed action.

(c) Merger or Asset Sale. In the event of a merger of the Company with or into another corporation, or the sale of substantially all of the assets of the Company, each outstanding Option and Stock Purchase Right shall be assumed or an equivalent option or right substituted by the successor corporation or a Parent or Subsidiary of the successor corporation. In the event that the successor corporation refuses to assume or substitute for the Option or Stock Purchase Right, the Optionee shall fully vest in and have the right to exercise the Option or Stock Purchase Right as to all of the Optioned Stock, including Shares as to which it would not otherwise be vested or exercisable. If an Option or Stock Purchase Right becomes fully vested and exercisable in lieu of assumption or substitution in the event of a merger or sale of assets, the Administrator shall notify the Optionee in writing or electronically that the Option or Stock Purchase Right shall be fully vested and exercisable for a period of fifteen (15) days from the date of such notice, and the Option or Stock Purchase Right shall terminate upon the expiration of such period. For the purposes of this paragraph, the Option or Stock Purchase Right shall be

A-8

considered assumed if, following the merger or sale of assets, the option or right confers the right to purchase or receive, for each Share of Optioned Stock subject to the Option or Stock Purchase Right immediately prior to the merger or sale of assets, the consideration (whether stock, cash, or other securities or property) received in the merger or sale of assets by holders of Common Stock for each Share held on the effective date of the transaction (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding Shares); provided, however, that if such consideration received in the merger or sale of assets is not solely common stock of the successor corporation or its Parent, the Administrator may, with the consent of the successor corporation, provide for the consideration to be received upon the exercise of the Option or Stock Purchase Right, for each Share of Optioned Stock subject to the Option or Stock Purchase Right, to be solely common stock of the successor corporation or its Parent equal in fair market value to the per share consideration received by holders of Common Stock in the merger or sale of assets.

14. Date of Grant. The date of grant of an Option or Stock Purchase Right shall be, for all purposes, the date on which the Administrator makes the determination granting such Option or Stock Purchase Right, or such other later date as is determined by the Administrator. Notice of the determination shall be provided to each Optionee within a reasonable time after the date of such grant.

15. Amendment and Termination of the Plan.

(a) Amendment and Termination. The Board may at any time amend, alter, suspend or terminate the Plan.

(b) Shareholder Approval. The Company shall obtain shareholder approval of any Plan amendment to the extent necessary and desirable to comply with Applicable Laws.

(c) Effect of Amendment or Termination. No amendment, alteration, suspension or termination of the Plan shall impair the rights of any Optionee, unless mutually agreed otherwise between the Optionee and the Administrator, which agreement must be in writing and signed by the Optionee and the Company. Termination of the Plan shall not affect the Administrator’s ability to exercise the powers granted to it hereunder with respect to Options granted under the Plan prior to the date of such termination.

16. Conditions Upon Issuance of Shares.

(a) Legal Compliance. Shares shall not be issued pursuant to the exercise of an Option or Stock Purchase Right unless the exercise of such Option or Stock Purchase Right and the issuance and delivery of such Shares shall comply with Applicable Laws and shall be further subject to the approval of counsel for the Company with respect to such compliance.

(b) Investment Representations. As a condition to the exercise of an Option or Stock Purchase Right, the Company may require the person exercising such Option or Stock Purchase Right 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.

17. Inability to Obtain Authority. 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.

18. Reservation of Shares. The Company, during the term of this Plan, will at all times reserve and keep available such number of Shares as shall be sufficient to satisfy the requirements of the Plan.

19. Shareholder Approval. The Plan shall be subject to approval by the shareholders of the Company within twelve (12) months after the date the Plan is adopted. Such shareholder approval shall be obtained in the manner and to the degree required under Applicable Laws.
