| Death                          | In the event of your death while in Service, then this Option will expire at the close of business at Company headquarters on the date which is one year after the date of death. During that one-year period, your estate or heirs may exercise the vested portion of this Option.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       |

However, for purposes of determining whether this Option is entitled to ISO status, your Service will be treated as terminating 90 days after you went on leave, unless your right to return to active work is guaranteed by law or by a contract. Your Service terminates in any event when the approved leave ends unless you immediately return to active work.The Company determines which leaves count toward Service, and when your Service terminates for all purposes under the Plan. |

| Restrictions on Exercise | Any other provision of this Stock Option Agreement notwithstanding, the Company shall have the right to designate one or more periods of time, each of which shall not exceed 180 days in length, during which this Option shall not be exercisable if the Company determines (in its sole discretion) that such limitation on exercise could in any way facilitate any issuance of securities by the Company, facilitate the registration or qualification of any securities by the Company under applicable law, or facilitate the perfection of any exemption from the registration or qualification requirements under any applicable law for the issuance or transfer of any securities.

| Withholding Taxes and Stock Withholding | You will not be allowed to exercise this Option unless you make arrangements acceptable to the Company to pay any withholding taxes that may be due as a result of the Option exercise. These arrangements may include withholding shares of Company stock that otherwise would be issued to you when you exercise this Option. The value of these shares, determined as of the effective date of the Option exercise, will be applied to the withholding taxes.                                                                                                                                                                                                                                                                                                                                                                                                                                                                       |
| Restrictions on Resale                  | By signing this Stock Option Agreement, you agree not to sell any Option shares at a time when applicable laws, regulations or Company or underwriter trading policies prohibit a sale. In connection with any underwritten public offering by the Company of its equity securities, you agree not to sell, make any short sale of, loan, hypothecate, pledge, grant any option for the purchase of, or otherwise dispose or transfer for value or agree to engage in any of the foregoing transactions with respect to any shares without the prior written consent of the Company or its underwriters, for such period of time after the effective date of such registration statement as may be requested by the Company or such underwriters. In order to enforce the provisions of this paragraph, the Company may impose stop-transfer instructions with respect to the shares until the end of the applicable stand-off period. |
| Transfer of Option            | In general, only you can exercise this Option prior to your death. You cannot transfer or assign this Option, other than as designated by you by will or by the laws of descent and distribution, except as provided below. For instance, you may not sell this Option or use it as security for a loan. If you attempt to do any of these things, this Option will immediately become invalid. You may in any event dispose of this Option in your will. Regardless of any marital property settlement agreement, the Company is not obligated to honor a notice of exercise from your former spouse, nor is the Company obligated to recognize your former spouse’s interest in your Option in any other way.                                                                                                                                                                                                                  |
|                                    | However, if this Option is designated as a nonstatutory stock option in the Notice of Stock Option Grant, then the Committee may, in its sole discretion, allow you to transfer this Option as a gift to one or more family members. For purposes of this Stock Option Agreement, “family member” means a child, stepchild, grandchild, parent, stepparent, grandparent, spouse, former spouse, sibling, niece, nephew, mother-in-law, father-in-law, or sister-in-law (including adoptive relationships), any individual sharing your household (other than a tenant or employee), a trust in which one or more of these individuals have more than 50% of the beneficial interest, a foundation in which you or one or more of these persons control the management of assets, and any entity in which you or one or more of these persons own more than 50% of the voting interest.                                     |
|                                    | In addition, if this Option is designated as a nonstatutory stock option in the Notice of Stock Option Grant, then the Committee may, in its sole discretion, allow you to transfer this option to your spouse or former spouse pursuant to a domestic relations order in settlement of marital property rights.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       |

|                          | The Committee will allow you to transfer this Option only if both you and the transferee(s) execute the forms prescribed by the Committee, which include the consent of the transferee(s) to be bound by this Stock Option Agreement.                                                                                                                                                                                                                                                                                                   |
|-------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| Retention Rights              | Neither your Option nor this Stock Option Agreement gives you the right to be retained by the Company or a subsidiary of the Company in any capacity. The Company and its subsidiaries reserve the right to terminate your Service at any time, with or without cause.                                                                                                                                                                                                                                                                  |
| Stockholder Rights            | You, or your estate or heirs, have no rights as a stockholder of the Company until you have exercised this Option by giving the required notice to the Company and paying the exercise price. No adjustments are made for dividends or other rights if the applicable record date occurs before you exercise this Option, except as described in the Plan.                                                                                                                                                                              |
| Adjustments                   | In the event of a stock split, a stock dividend or a similar change in Company stock, the number of shares covered by this Option and the exercise price per share may be adjusted pursuant to the Plan.                                                                                                                                                                                                                                                                                                                                |
| Applicable Law                | This Stock Option Agreement will be interpreted and enforced under the laws of the State of California (without regard to its choice of law rules).                                                                                                                                                                                                                                                                                                                                                                                     |
| The Plan and Other Agreements | The text of the Plan is incorporated in this Stock Option Agreement by reference. All capitalized terms not defined in this Stock Option Agreement shall have the meanings assigned to them in the Plan. This Stock Option Agreement and the Plan constitute the entire understanding between you and the Company regarding this Option. Any prior agreements, commitments or negotiations concerning this Option are superseded. This Stock Option Agreement may be amended only by another written agreement, signed by both parties. |

| 1. | I understand that all sales of Purchased Shares are subject to compliance with the Company’s policy on securities trades.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    |

| 2. | I hereby acknowledge that I received and read a copy of the prospectus describing the Company’s 2006 Stock Incentive Plan and the tax consequences of an exercise.                                                                                                                                                                                                                                                                                                                                                                                                                                           |
| 3. | In the case of a nonstatutory option, I understand that I must recognize ordinary income equal to the spread between the fair market value of the Purchased Shares on the date of exercise and the exercise price. I further understand that I am required to pay withholding taxes at the time of exercising a nonstatutory option.                                                                                                                                                                                                                                                                               |
| 4. | In the case of an incentive stock option, I agree to notify the Company if I dispose of the Purchased Shares before I have met both of the tax holding periods applicable to incentive stock options (that is, if I make a disqualifying disposition).                                                                                                                                                                                                                                                                                                                                                             |
| 5. | I acknowledge that the Company has encouraged me to consult my own adviser to determine the form of ownership that is appropriate for me. In the event that I choose to transfer my Purchased Shares to a trust that does not satisfy the requirements of the Internal Revenue Service (i.e., a trust that is not an eligible revocable trust), I also acknowledge that the transfer will be treated as a “disposition” for incentive stock option tax purposes. As a result, the favorable incentive stock option tax treatment will be unavailable and other unfavorable tax consequences may occur. |
