STOCK OPTION AGREEMENT

RECITALS

A.    The Board has adopted the Plan for the purpose of retaining the services of selected Employees, non-employee members of the Board or the board of directors of any Parent or Subsidiary and consultants and other independent advisors in the service of the Corporation (or any Parent or Subsidiary).

B.    Optionee is to render valuable services to the Corporation (or a Parent or Subsidiary), and this Agreement is executed pursuant to, and is intended to carry out the purposes of, the Plan in connection with the Corporation’s grant of an option to Optionee.

C.    All capitalized terms in this Agreement shall have the meaning assigned to them in the attached Appendix.

NOW, THEREFORE, it is hereby agreed as follows:

1.    Grant of Option. The Corporation hereby grants to Optionee, as of the Grant Date, an option to purchase up to the number of Option Shares specified in the Grant Notice. The Option Shares shall become purchasable from time to time during the option term specified in Paragraph 2 at the Exercise Price, according to the Vesting Schedule provided in Optionee’s Grant Notice.

2.    Option Term. This option shall have a term of ten (10) years measured from the Grant Date and shall accordingly expire at the close of business on the Expiration Date, unless sooner terminated in accordance with Paragraph 5 or 6.

3.    Limited Transferability.

(a)    This option shall be neither transferable nor assignable by Optionee other than as set forth in this Agreement and the Plan. Optionee may designate one or more persons as the beneficiary or beneficiaries of this option, and this option shall, in accordance with such designation, automatically be transferred to such beneficiary or beneficiaries upon the Optionee’s death while holding this option. Such beneficiary or beneficiaries shall take the transferred option subject to all the terms and conditions of this Agreement, including (without limitation) the limited time period during which this option may, pursuant to Paragraph 5, be exercised following Optionee’s death.

(b)    This option may be assigned in whole or in part during Optionee’s lifetime to one or more members of Optionee’s family or to a trust established for the exclusive benefit of one or more such family members or to Optionee’s former spouse, to the extent such assignment is in connection with the Optionee’s estate plan or pursuant to a

1

domestic relations order. The assigned portion shall be exercisable only by the person or persons who acquire a proprietary interest in the option pursuant to such assignment. The terms applicable to the assigned portion shall be the same as those in effect for this option immediately prior to such assignment.

4.    Dates of Exercise. This option shall become exercisable for the Option Shares in one or more installments as specified in the Grant Notice. As the option becomes exercisable for such installments, those installments shall accumulate, and the option shall remain exercisable for the accumulated installments until the Expiration Date or sooner termination of the option term under Paragraph 5 or 6.

5.    Cessation of Service. The option term specified in Paragraph 2 shall terminate (and this option shall cease to be outstanding) prior to the Expiration Date should any of the following provisions become applicable:

(a)    Should Optionee cease to remain in Service for any reason (other than death, Disability or Misconduct) while holding this option, then Optionee shall have a period of three (3) months (commencing with the date of such cessation of Service) during which to exercise this option, but in no event shall this option be exercisable at any time after the Expiration Date.

(b)    Should Optionee die while holding this option, then the personal representative of Optionee’s estate or the person or persons to whom the option is transferred pursuant to Optionee’s will or the laws of inheritance shall have the right to exercise this option. However, if Optionee has designated one or more beneficiaries of this option, then those persons shall have the exclusive right to exercise this option following Optionee’s death. Any such right to exercise this option shall lapse, and this option shall cease to be outstanding, upon the earlier of (i) the expiration of the twelve (12)-month period measured from the date of Optionee’s death or (ii) the Expiration Date.

(c)    Should Optionee cease Service by reason of Disability while holding this option, then Optionee shall have a period of twelve (12) months (commencing with the date of such cessation of Service) during which to exercise this option. In no event shall this option be exercisable at any time after the Expiration Date.

(d)    During the limited period of post-Service exercisability, this option may not be exercised in the aggregate for more than the number of Option Shares in which Optionee is, at the time of Optionee’s cessation of Service, vested pursuant to the Vesting Schedule specified in the Grant Notice or the special vesting acceleration provisions of Paragraph 6. Upon the expiration of such limited exercise period or (if earlier) upon the Expiration Date, this option shall terminate and cease to be outstanding for any vested Option Shares for which the option has not been exercised. To the extent Optionee is not vested in one or more Option Shares at the time of Optionee’s cessation of Service, this option shall immediately terminate and cease to be outstanding with respect to those shares.

2

(e)    Should Optionee’s Service be terminated for Misconduct or should Optionee otherwise engage in Misconduct while this option is outstanding, then this option shall terminate immediately and cease to remain outstanding.

6. Accelerated Vesting.

(a)    In the event of any Corporate Transaction, the Option Shares at the time subject to this option but not otherwise vested shall automatically vest in full so that this option shall, immediately prior to the effective date of the Corporate Transaction, become exercisable for all of the Option Shares as fully-vested shares and may be exercised for any or all of those Option Shares as vested shares. However, the Option Shares shall not vest on such an accelerated basis if and to the extent: (i) this option is assumed by the successor corporation (or parent thereof) in the Corporate Transaction and the Corporation’s repurchase rights with respect to the unvested Option Shares are assigned to such successor corporation (or parent thereof) or (ii) this option is to be replaced with a cash incentive program of the successor corporation which preserves the spread existing on the unvested Option Shares at the time of the Corporate Transaction (the excess of the Fair Market Value of those Option Shares over the Exercise Price payable for such shares) and provides for subsequent payout in accordance with the same Vesting Schedule applicable to those unvested Option Shares as set forth in the Grant Notice.

(b)    Immediately following the Corporate Transaction, this option shall terminate and cease to be outstanding, except to the extent assumed by the successor corporation (or parent thereof) in connection with the Corporate Transaction.

(c)    If this option is assumed in connection with a Corporate Transaction, then this option shall be appropriately adjusted, immediately after such Corporate Transaction, to apply to the number and class of securities which would have been issuable to Optionee in consummation of such Corporate Transaction had the option been exercised immediately prior to such Corporate Transaction, and appropriate adjustments shall also be made to the Exercise Price, provided the aggregate Exercise Price shall remain the same. To the extent the actual holders of the Corporation’s outstanding Common Stock receive cash consideration for their Common Stock in consummation of the Corporate Transaction, the successor corporation may, in connection with the assumption of this option, substitute one or more shares of its own common stock with a fair market value equivalent to the cash consideration paid per share of Common Stock in such Corporate Transaction.

(d)    This Agreement shall not in any way affect the right of the Corporation to adjust, reclassify, reorganize or otherwise change its capital or business structure or to merge, consolidate, dissolve, liquidate or sell or transfer all or any part of its business or assets.

(e)    Notwithstanding any other provision of this Agreement, upon an Involuntary Termination of Optionee’s Service within              months following the Corporate Transaction, all the Option Shares at the time subject to the Option shall automatically vest on an accelerated basis so that the Option shall immediately become

3

exercisable for              of the Option Shares as fully-vested shares and may be exercised for any or all of those Option Shares as vested shares. The Option shall remain so exercisable until the earlier of (i) the Expiration Date, or (ii) the expiration of the              period measured from the date of the Involuntary Termination.

7.    Adjustment in Option Shares. Should any change be made to the Common Stock by reason of any stock split, stock dividend, recapitalization, combination of shares, exchange of shares or other change affecting the outstanding Common Stock as a class without the Corporation’s receipt of consideration, appropriate adjustments shall be made to (i) the total number and/or class of securities subject to this option and (ii) the Exercise Price in order to reflect such change and thereby preclude a dilution or enlargement of benefits hereunder.

8.    Stockholder Rights. The holder of this option shall not have any stockholder rights with respect to the Option Shares until such person shall have exercised the option, paid the Exercise Price and become the record holder of the purchased shares.

(a)    In order to exercise this option with respect to all or any part of the Option Shares for which this option is at the time exercisable, Optionee (or any other person or persons exercising the option) must take the following actions:

(i)    Execute and deliver to the Corporation a Purchase Agreement for the Option Shares for which the option is exercised.

(ii)    Pay the aggregate Exercise Price for the purchased shares in one or more of the following forms:

(A)    cash or check made payable to the Corporation; or

(B)    a promissory note payable to the Corporation, but only to the extent authorized by the Plan Administrator in accordance with Paragraph 14.

Should the Common Stock be registered under Section 12 of the 1934 Act at the time the option is exercised, then the Exercise Price may also be paid as follows:

(C)    in shares of Common Stock held by Optionee (or any other person or persons exercising the option) for the requisite period necessary to avoid a charge to the Corporation’s earnings for financial reporting purposes and valued at Fair Market Value on the Exercise Date; or

(D)    to the extent the option is exercised for vested Option Shares, through a special sale and remittance procedure pursuant to which Optionee (or any other person or persons exercising the option) shall concurrently provide irrevocable instructions (a) to a Corporation-designated

4

brokerage firm to effect the immediate sale of the purchased shares and remit to the Corporation, out of the sale proceeds available on the settlement date, sufficient funds to cover the aggregate Exercise Price payable for the purchased shares plus all applicable Federal, state and local income and employment taxes required to be withheld by the Corporation by reason of such exercise and (b) to the Corporation to deliver the certificates for the purchased shares directly to such brokerage firm in order to complete the sale.

Except to the extent the sale and remittance procedure is utilized in connection with the option exercise, payment of the Exercise Price must accompany the Purchase Agreement delivered to the Corporation in connection with the option exercise.

(iii)    Furnish to the Corporation appropriate documentation that the person or persons exercising the option (if other than Optionee) have the right to exercise this option.

(iv)    Execute and deliver to the Corporation such written representations as may be requested by the Corporation in order for it to comply with the applicable requirements of Federal and state securities laws.

(v)    Make appropriate arrangements with the Corporation (or Parent or Subsidiary employing or retaining Optionee) for the satisfaction of all Federal, state and local income and employment tax withholding requirements applicable to the option exercise.

(b)    As soon as practical after the Exercise Date, the Corporation shall issue to or on behalf of Optionee (or any other person or persons exercising this option) a certificate for the purchased Option Shares, with the appropriate legends affixed thereto.

(c)    In no event may this option be exercised for any fractional shares.

9.    RIGHTS OF FIRST REFUSAL. ALL OPTION SHARES ACQUIRED UPON THE EXERCISE OF THIS OPTION SHALL BE SUBJECT TO CERTAIN RIGHTS OF FIRST REFUSAL OF THE CORPORATION AND ITS ASSIGNS IN ACCORDANCE WITH THE TERMS SPECIFIED IN THE PURCHASE AGREEMENT.

10.    Compliance with Laws and Regulations.

(a)    The exercise of this option and the issuance of the Option Shares upon such exercise shall be subject to compliance by the Corporation and Optionee with all applicable requirements of law relating thereto and with all applicable regulations of any stock exchange (or the Nasdaq National Market, if applicable) on which the Common Stock may be listed for trading at the time of such exercise and issuance.

5

(b)    The inability of the Corporation to obtain approval from any regulatory body having authority deemed by the Corporation to be necessary to the lawful issuance and sale of any Common Stock pursuant to this option shall relieve the Corporation of any liability with respect to the non-issuance or sale of the Common Stock as to which such approval shall not have been obtained. The Corporation, however, shall use its best efforts to obtain all such approvals.

11.    Successors and Assigns. Except to the extent otherwise provided in Paragraphs 3 and 6, the provisions of this Agreement shall inure to the benefit of, and be binding upon, the Corporation and its successors and assigns and Optionee, Optionee’s assigns and the legal representatives, heirs and legatees of Optionee’s estate.

12.    Notices. Any notice required to be given or delivered to the Corporation under the terms of this Agreement shall be in writing and addressed to the Corporation 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 below Optionee’s signature line on the Grant Notice. All notices shall be deemed effective upon personal delivery or upon deposit in the U.S. mail, postage prepaid and properly addressed to the party to be notified.

13.    Financing. The Plan Administrator may, in its absolute discretion and without any obligation to do so, permit Optionee to pay the Exercise Price for the purchased Option Shares (to the extent such Exercise Price is in excess of the par value of those shares) by delivering a full-recourse, interest-bearing promissory note secured by those Option Shares. The payment schedule in effect for any such promissory note shall be established by the Plan Administrator in its sole discretion.

14.    Construction. This Agreement and the option evidenced hereby are made and granted pursuant to the Plan and are in all respects limited by and subject to the terms of the Plan. All decisions of the Plan Administrator with respect to any question or issue arising under the Plan or this Agreement shall be conclusive and binding on all persons having an interest in this option.
