3.2 Termination Because of Death. If the Optionee is Terminated because of Optionee’s death (or the Optionee dies within three (3) months after a Termination other than for Cause or because of the Optionee’s Disability), then the Option may be exercised only to the extent that such Option would have been exercisable by the Optionee on the Termination Date and must be exercised by the Optionee’s legal representative or authorized assignee no later than twelve (12) months after the Termination Date (or such shorter time period not less than six (6) months or longer time period not exceeding five (5) years as may be determined by the Committee, but in any event no later than the Expiration Date.

4. Manner of Exercise.

4.1 Stock Option Exercise Agreement. To exercise this Option, Optionee (or in the case of exercise after Optionee’s death, Optionee’s executor, administrator, heir or legatee, as the case may be) must deliver to the Company an executed stock option exercise agreement in the form attached hereto as Exhibit A, or in such other form as may be approved by the Company from time to time (the “Exercise Agreement”), which shall set forth, inter alia, Optionee’s election to exercise this Option, the number of shares being purchased, any restrictions imposed on the Shares and any representations, warranties and agreements regarding Optionee’s investment intent and access to information as may be required by the Company to comply with applicable securities laws. If someone other than Optionee exercises this Option, then such person must submit documentation reasonably acceptable to the Company that such person has the right to exercise this Option.

4.2 Limitations on Exercise. This Option may not be exercised unless such exercise is in compliance with all applicable federal and state securities laws, as they are in effect on the date of exercise. This Option may not be exercised as to fewer than 100 Shares unless it is exercised as to all Shares as to which this Option is then exercisable.

4.3 Payment. Payment of the aggregate Exercise Price shall be by any of the following, or a combination thereof, at the election of the Optionee:

(a) cash; or

(b) check; or

(c) “same day sale” (as described in Section 12.1(d)(1) of the Plan), subject to the Company’s insider trading policies; or

(d) other method authorized by the Company.

4.4 Tax Withholding. Prior to the issuance of the Shares upon exercise of this Option, Optionee must pay or provide for any applicable federal or state withholding obligations of the Company. If the Committee permits, Optionee may provide for payment of withholding taxes upon exercise of this Option by requesting that the Company retain Shares with a Fair Market Value equal to the minimum amount of taxes required to be withheld. In such case, the Company shall issue the net number of Shares to the Optionee by deducting the Shares retained from the Shares issuable upon exercise.

4.5 Issuance of Shares. Provided that the Exercise Agreement and payment are in form and substance satisfactory to counsel for the Company, the Company shall issue the Shares registered in the name of Optionee, Optionee’s authorized assignee, or Optionee’s legal representative, and shall deliver certificates representing the Shares with the appropriate legends affixed thereto.

5. Compliance with Laws and Regulations. The exercise of this Option and the issuance and transfer of Shares shall be subject to compliance by the Company and Optionee with all applicable requirements of federal and state securities laws and with all applicable requirements of any stock exchange on which the Company’s Common Stock may be listed at the time of such issuance or transfer. Optionee understands that the Company is under no obligation to register or qualify the Shares with the Securities and Exchange Commission (“SEC”), any state securities commission or any stock exchange to effect such compliance.

6. Nontransferability of Option. This Option may not be transferred in any manner other than by will or by the laws of descent and distribution and may be exercised during the lifetime of Optionee only by Optionee. The terms of this Option shall be binding upon the executors, administrators, successors and assigns of Optionee.

7. Tax Consequences. Set forth below is a brief summary of some of the federal and California tax consequences of exercise of this Option and disposition of the Shares. THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE. OPTIONEE SHOULD CONSULT A TAX ADVISOR BEFORE EXERCISING THE OPTION OR DISPOSING OF THE SHARES.

7.1 Exercise of Nonqualified Stock Option. There may be a regular federal and California income tax liability upon the exercise of this Option. Optionee will be treated as having received compensation income (taxable at ordinary income tax rates) equal to the excess, if any, of the fair market value of the Shares on the date of exercise over the Exercise Price. The Company will be required to withhold from Optionee’s compensation or collect from Optionee and pay to the applicable taxing authorities an amount equal to a percentage of this compensation income at the time of exercise.

7.2 Disposition of Shares. If the Shares are held for more than twelve (12) months after the date of the transfer of the Shares pursuant to the exercise of an NQSO, any gain realized on disposition of the Shares will be treated as long-term capital gain, as the case may be.

8. Privileges of Stock Ownership. Optionee shall not have any of the rights of a shareholder with respect to any Shares until Optionee exercises this Option and pays the Exercise Price.

9. Interpretation. Any dispute regarding the interpretation of this Agreement shall be submitted by Optionee or the Company to the Committee for review. The resolution of such a dispute by the Committee shall be final and binding on the Company and Optionee.

10. Entire Agreement. This Agreement, the Exercise Agreement and the Change in Control Agreement constitute the entire agreement and understanding of the parties hereto with respect to the subject matter hereof and supersede all prior understandings and agreements with respect to such subject matter.

11. Notices. Any notice required to be given or delivered to the Company under the terms of this Agreement shall be in writing and addressed to the Corporate Secretary of the Company at its principal corporate offices. Any notice required to be given or delivered to Optionee shall be in writing and addressed to Optionee at the address indicated above or to such other address as such party may designate in writing from time to time to the Company. All notices shall be deemed to have been given or delivered upon: personal delivery; three (3) days after deposit in the United States mail by certified or registered mail (return receipt requested); one (1) business day after deposit with any return receipt express courier (prepaid); or one (1) business day after transmission via electronic means.

12. Successors and Assigns. The Company may assign any of its rights under this Agreement. This Agreement shall be binding upon and inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer set forth herein, this Agreement shall be binding upon Optionee and Optionee’s heirs, executors, administrators, legal representatives, successors and assigns.

13. Governing Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of California, without regard to that body of law pertaining to choice of law or conflict of law.

14. Acceptance. Optionee hereby acknowledges receipt of a copy of this Agreement. Optionee has read and understands the terms and provisions thereof, and accepts this Option subject to all the terms and conditions of this Agreement. Optionee acknowledges that there may be adverse tax consequences upon exercise of this Option or disposition of the Shares and that the Company has advised Optionee to consult a tax advisor prior to such exercise or disposition.

15. Modification, Extension or Renewal. The Committee may modify, extend or renew this Option and authorize the grant of new options in substitution therefor, provided that any such action may not, without the written consent of the Optionee, impair any of such Optionee’s rights under this Option. The Committee may reduce the Exercise Price of this Option without the consent of the Optionee affected by a written notice to them; provided, however, that the Exercise Price may not be reduced below 85% of the Fair Market Value of the Shares on the date of grant.

16. Certificates. All certificates for Shares or other securities delivered upon exercise of this Option will be subject to such stock transfer orders, legends and other restrictions as the Committee may deem necessary or advisable, including restrictions under any applicable federal, state or foreign securities law, or any rules, regulations and other requirements of the SEC or any stock exchange or automated quotation system upon which the Shares may be listed or quoted.

17. Adjustment of Shares. In the event that the number of outstanding shares is changed by a stock dividend, recapitalization, stock split, reverse stock split, subdivision, combination, reclassification or similar change in the capital structure of the Company without consideration, then the Exercise Price of and the number of Shares subject to this Option will be

proportionately adjusted, subject to any required action by the Board or the Optionee and compliance with applicable securities laws; provided, however, that fractions of a Share will not be issued but will either be replaced by a cash payment equal to the Fair Market Value of such fraction of a Share or will be rounded up to the nearest whole Share, as determined by the Committee.

18. Corporate Transactions.

18.1 Assumption or Replacement of Option by Successor. 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, the Option shall be assumed or an equivalent award substituted by the successor corporation (including as a “successor” any purchaser of substantially all of the assets of the Company) or a parent or subsidiary of the successor corporation. In the event that the successor corporation refuses to assume or substitute for the Option, the Optionee shall have the right to exercise the Option as to all of the shares of Common Stock covered by the Option, including Shares as to which it would not otherwise be exercisable. If an Option is exercisable in lieu of assumption or substitution in the event of a merger or sale of assets, the Company shall notify the Optionee that the Option shall be fully exercisable for a period of fifteen (15) days from the date of such notice, and the Option shall terminate upon the expiration of such period. For the purposes of this paragraph, the Option shall be considered assumed if, following the merger or sale of assets, the Option confers the right to purchase or receive, for each share of Common Stock subject to the Option 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 was not solely common stock of the successor corporation or its parent entity, the Company may, with the consent of the successor corporation, provide for the consideration to be received upon the exercise of the Option, for each share of Common Stock subject to the Option, to be solely common stock of the successor corporation or its parent entity equal in fair market value to the per share consideration received by holders of Common Stock in the merger or sale of assets.

18.2 Other Treatment of Option. Subject to any greater rights granted to the Optionee under the foregoing provisions of this section, in the event of the occurrence of any transaction described in Section 18.1, this Option will be treated as provided in the applicable agreement or plan of merger, consolidation, dissolution, liquidation, or sale of assets.

19. Amendment or Termination of the Agreement. The Board may at any time terminate or amend this Agreement in any respect; provided, however, that the Board will not, without the approval of the Optionee, amend this Agreement in any manner that requires Optionee’s approval.

20. Definitions. As used in this Agreement, the following terms will have the following meanings:

“Board” means the Board of Directors of the Company.

“Cause” has the meaning set forth in the Change of Control Agreement.

“Committee” means the Compensation Committee of the Board.

“Disability” means a disability, whether temporary or permanent, partial or total, as determined by the Committee.

“Exercise Price” means the price at which a holder of an Option may purchase the Shares issuable upon exercise of the Option.

“Fair Market Value” means, as of any date, the value of a share of the Company’s Common Stock determined as follows:

(a) if such Common Stock is publicly traded and is then listed on a national securities exchange, its closing price on the date of determination on the principal national securities exchange on which the Common Stock is listed or admitted to trading as reported in The Wall Street Journal;

(b) if such Common Stock is publicly traded but is not quoted on the Nasdaq Stock Market nor listed or admitted to trading on a national securities exchange, the average of the closing bid and asked prices on the date of determination as reported in The Wall Street Journal; or

(c) if none of the foregoing is applicable, by the Committee in good faith.

“Parent” means any corporation (other than the Company) in an unbroken chain of corporations ending with the Company if each of such corporations other than the Company owns stock possessing 50% or more of the total combined voting power of all classes of stock in one of the other corporations in such chain.

“Subsidiary” means any corporation (other than the Company) in an unbroken chain of corporations beginning with the Company if each of the corporations other than the last corporation in the unbroken chain owns stock possessing 50% or more of the total combined voting power of all classes of stock in one of the other corporations in such chain.

“Termination” or “Terminated” means, for purposes of this Agreement with respect to the Optionee, that the Optionee has for any reason ceased to provide services as an employee, officer, director, consultant, independent contractor, or advisor to the Company or a Parent or Subsidiary of the Company. An employee will not be deemed to have ceased to provide services in the case of (i) sick leave, (ii) military leave, or (iii) any other leave of absence approved by the Committee, provided, that such leave is for a period of not more than 90 days, unless reemployment upon the expiration of such leave is guaranteed by contract or statute or unless provided otherwise pursuant to formal policy adopted from time to time by the Company and issued and promulgated to employees in writing. In the case of the Optionee is on

an approved leave of absence, the Committee may make such provisions respecting suspension of vesting of this Option while on leave from the employ of the Company or a Subsidiary as it may deem appropriate, except that in no event may this Option be exercised after the expiration of the term set forth in this Agreement. The Committee will have sole discretion to determine whether the Optionee has ceased to provide services and the effective date on which the Optionee ceased to provide services (the “Termination Date”).

IN WITNESS WHEREOF, the Company has caused this Agreement to be executed in duplicate by its duly authorized representative and Optionee has executed this Agreement in duplicate as of the Date of Grant.
