Grant of Stock Options. The Company has granted to the Participant, effective as of the Date of Grant, the right and option to purchase, on the terms and conditions set forth in the Plan and this Agreement, all or any part of an aggregate of              Shares, subject to adjustment as set forth in the Plan (the “Options”). The Options are intended to be Nonqualified Stock Options.

Exercise Price. The exercise price of each Option is $             per Share, subject to adjustment as set forth in the Plan (the “Exercise Price”).

Vesting of Options. The Options shall be eligible to vest, if at all, on the basis of the time-vesting criteria set forth on Schedule A attached hereto

Expiration.

Termination of Service. Any unvested Options will be forfeited immediately, automatically and without consideration upon a termination of the Participant’s Service for any reason. In the event the Participant’s Service is terminated for Cause, all vested Options will also be forfeited immediately, automatically and without consideration upon such termination for Cause. Without limiting the generality of the foregoing, the Options and the Shares (and any resulting proceeds) will continue to be subject to the Plan.

Any unexercised Options will expire on the tenth (10th) anniversary of the Date of Grant (the “Expiration Date”), or earlier as provided in Section 5 of this Agreement or in the Plan.

Period of Exercise. Subject to the provisions of the Plan and this Agreement, the Participant may exercise all or any part of the vested Options at any time prior to the earliest to occur of:

the Expiration Date;

the date that is twelve (12) months following termination of the Participant’s Service due to death or Disability;

the date that is ninety (90) days following an involuntary termination of the Participant’s Service without Cause;

the date that is thirty (30) days following termination of the Participant’s Service other than for death, Disability or with or without Cause; or

the date of termination of the Participant’s Service for Cause.

Exercise of Options

Notice of Exercise. Subject to Sections 4 and 5, the Participant or, in the case of the Participant’s death or Disability, the Participant’s representative may exercise all or any part of the vested Options (covering whole Shares) through a written election in a form provided by the Company (a “Notice of Exercise”). The Notice of Exercise will be executed by the person exercising the Options. In the event that the Options are being exercised by the Participant’s representative, the Notice of Exercise will be accompanied by proof (satisfactory to the Committee) of the representative’s right to exercise the Options. The Participant or the Participant’s representative will deliver to the Committee, at the time of giving the Notice of Exercise, payment in a form permissible under Section 7 for the full amount of the Purchase Price (as defined below) and applicable withholding taxes as provided below.

Issuance of Shares. After all requirements with respect to the exercise of the Options have been satisfied, the Committee will cause the Shares as to which the Options have been exercised to be issued (or, in the Committee’s discretion, in un-certificated form, upon the books of the Company’s transfer agent), registered in the name of the person exercising the Options (or in the names of such person and his or her spouse as community property or as joint tenants with right of survivorship). Neither the Company nor the Committee will be liable to the Participant or any other Person for damages relating to any delays in issuing the Shares or any mistakes or errors in the issuance of the Shares.

Withholding Requirements. The Company shall have the power and the right to deduct or withhold automatically from any Shares deliverable under this Agreement, or to require the Participant or the Participant’s representative to remit to the Company, the minimum statutory amount necessary to satisfy federal, state and local taxes, domestic or foreign, required by law or regulation to be withheld with respect to any taxable event arising as a result of this Agreement, or in the sole discretion of the Committee, such greater amount necessary to satisfy the Participant’s expected tax liability, provided that, the withholding of such greater amount does not result in adverse tax or accounting consequences to the Company (collectively, “Withheld Taxes”); provided further, that any obligations to pay Withheld Taxes may be satisfied in the manner in which the Purchase Price is permitted to be paid under Section 7 or any other manner permitted by the Plan.

Payment for Shares. The “Purchase Price” will be the Exercise Price multiplied by the number of Shares with respect to which Options are being exercised. All or part of the Purchase Price and any Withheld Taxes may be paid as follows:

Cash or Check. In cash or by bank certified check.

Brokered Cashless Exercise. To the extent permitted by the Committee, from the proceeds of a sale through a broker on the date of exercise of some or all of the Shares to which the exercise relates. In that case, the Participant will execute a Notice of Exercise and provide the Company’s third-party Plan administrator with a copy of irrevocable instructions to a broker to deliver promptly to the Company the amount of sale proceeds to pay the aggregate purchase price and/or Withheld Taxes, as applicable. To facilitate the foregoing, the Company may, to the extent permitted by applicable law, enter into agreements or coordinate procedures with one or more brokerage firms.

Net Exercise. To the extent permitted by the Committee, by reducing the number of Shares otherwise deliverable upon the exercise of the Options by the number of Shares having a Fair Market Value equal to the amount of the Purchase Price and, at the sole discretion of the Committee, Withheld Taxes, as applicable.

Surrender of Stock. In each instance, at the sole discretion of the Committee, by surrendering, or attesting to the ownership of, Shares that are already owned by the Participant free and clear of any restriction or limitation, unless the Committee specifically agrees in writing to accept such Shares subject to such restriction or limitation. Such Shares will be surrendered to the Company in good form for transfer and will be valued by the Company at their Fair Market Value on the date of the applicable exercise of the Options, or to the extent applicable, on the date the Withheld Taxes are to be determined. The Participant will not surrender, or attest to the ownership of, Shares in payment of the Purchase Price (or Withheld Taxes) if such action would cause the Company to recognize compensation expense (or additional compensation expense) with respect to the Options for financial reporting purposes that otherwise would not have been recognized.

Adjustment to Options. In the event of any change with respect to the outstanding shares of Common Stock contemplated by Section 4.3of the Plan, the Options may be adjusted in accordance with Section 4.3 of the Plan.

[Reserved.]

Miscellaneous Provisions

The Committee may impose such conditions on any Shares issuable pursuant to this Agreement as it may deem advisable, including, without limitation, restrictions under the Securities Act, as amended, under the requirements of any exchange upon which shares of the same class are then listed and under any blue sky or other securities laws applicable to those Shares.

Rights of a Shareholder of the Company.

Transfer Restrictions.

No Right to Continued Service. Nothing in this Agreement or the Plan confers upon the Participant any right to continue in Service for any period of specific duration or interfere with or otherwise restrict in any way the rights of the Company (or any Subsidiary employing or retaining the Participant) or of the Participant, which rights are hereby expressly reserved by each, to terminate his or her Service at any time and for any reason, with or without Cause.

Severability. The provisions of this Agreement are severable, and if any one or more provisions are determined to be illegal or otherwise unenforceable, in whole or in part, then the remaining provisions will nevertheless be binding and enforceable.

Amendment. Except as otherwise provided in the Plan, this Agreement will not be amended unless the amendment is agreed to in writing by both the Participant and the Company.

Choice of Law; Jurisdiction. This Agreement and all claims, causes of action or proceedings (whether in contract, in tort, at law or otherwise) that may be based upon, arise out of or relate to this Agreement will be governed by the internal laws of the State of Delaware, excluding any conflicts or choice-of-law rule or principle that might otherwise refer construction or interpretation of this Agreement to the substantive law of another jurisdiction.
