WHEREAS, the Optionee performs services for the Company and/or one of its Subsidiaries; and

WHEREAS, the Committee responsible for administration of the Plan has determined to grant the Option to the Optionee as provided herein.

NOW, THEREFORE, the parties hereto agree as follows:

1. Grant of Option.

1.2 The Option is not intended to qualify as an Incentive Stock Option within the meaning of Section 422 of the Code.

1.3 This Agreement shall be construed in accordance and consistent with, and subject to, the provisions of the Plan (the provisions of which are incorporated herein by reference) and, except as otherwise expressly set forth herein, the capitalized terms used in this Agreement shall have the same definitions as set forth in the Plan.

1.4 The Option is conditioned upon Optionee’s execution of this Agreement. If the Agreement is not executed by the Optionee, the Option may be canceled by the Committee.

The price at which the Optionee shall be entitled to purchase Shares upon the exercise of the Option shall be $                     per Share.

3. Duration of Option.

The Option shall be exercisable to the extent and in the manner provided herein for a period of ten (10) years from the Grant Date (the “Exercise Term”); provided, however, that the Option may be earlier terminated as provided in Sections 1.4 and 6 hereof.

4. Vesting and Exercisability of Option.

The Option shall vest, and may be exercised, with respect to the Shares as set forth in the Optionee Statement attached hereto and made a part hereof, subject to earlier termination of the Option as provided in Sections 1.4 and 6 hereof or in the Plan. The right to purchase the Shares as they become vested shall be cumulative and shall continue during the Exercise Term unless sooner terminated as provided herein.

5. Manner of Exercise and Payment.

5.1 Subject to the terms and conditions of this Agreement and the Plan, the Option may be exercised by either (i) delivery of written notice to the Company, at its principal executive office or (ii) online notice given to an online broker with which the Company has made arrangement for the exercise of employee stock options, which notice satisfies the form and conditions set forth in such arrangement, which shall be provided to the Grantee from time to time. Such notice shall state that the Optionee is electing to exercise the Option and the number of Shares in respect of which the Option is being exercised and, if delivered in writing to the Company, shall be signed by the person or persons exercising the Option. If requested by the Committee, such person or persons shall (i) deliver this Agreement to the Secretary of the Company who shall endorse thereon a notation of such exercise and (ii) provide satisfactory proof as to the right of such person or persons to exercise the Option.

Any Shares the Optionee transfers to the Company or attests to owning as payment of the purchase price under an Option shall be valued at their Fair Market Value on the day preceding the date of exercise of such Option.

5.3 Upon receipt of notice of exercise and full payment for the Shares in respect of which the Option is being exercised, the Company shall, subject to Section 16 of the Plan, take such action as may be necessary to effect the transfer to the Optionee of the number of Shares as to which such exercise was effective.

5.4 The Optionee shall not be deemed to be the holder of, or to have any of the rights of a holder with respect to any Shares subject to the Option until (i) the Option shall have been exercised pursuant to the terms of this Agreement and the Optionee shall have paid the full

Appropriate evidence of any such transfer to the Permitted Transferees shall be delivered to the Company at its principal executive office. If all or part of the Option is transferred to a Permitted Transferee, the Permitted Transferee’s rights hereunder shall be subject to the same restrictions and limitations with respect to the Option as the Optionee.

10. Adjustments.

In the event of a Change in Capitalization, the Committee may make appropriate adjustments to the number and class of Shares or other stock or securities subject to the Option and the purchase price for such Shares or other stock or securities.
