1.          Grant of Option. The Option granted to the Grantee and described in the Notice of Grant is subject to the terms and conditions of the Plan. The terms and conditions of the Plan are hereby incorporated herein by reference. Except as otherwise expressly set forth herein, the Award Agreement shall be construed in accordance with the terms and conditions of the Plan. Any capitalized term not otherwise defined in the Award Agreement shall have the definition set forth in the Plan.

The Committee has approved the grant to the Grantee of the Option, conditioned upon the Grantee’s acceptance of the terms and conditions of the Award Agreement within 60 days after the Award Agreement is presented to the Grantee for review.

The Option shall be treated as a non-qualified stock option.

2.          Exercise of Option.

(a)          Right to Exercise. The Option shall be exercisable, in whole or in part, during its term in accordance with the Exercisability Schedule set forth in the Notice of Grant and with the applicable provisions of the Plan and the Award Agreement. No Shares shall be issued pursuant to the exercise of the Option unless the issuance and exercise comply with applicable laws. Assuming such compliance, for income tax purposes the Shares shall be considered transferred to the Grantee on the date on which the Option is exercised with respect to such Shares. Until such time as the Option has been duly exercised and Shares have been delivered, the Grantee shall not be entitled to exercise any voting rights with respect to such Shares, shall not be entitled to receive dividends or other distributions with respect thereto and shall not have any other rights of a stockholder with respect thereto.

(b)          Method of Exercise. The Grantee may exercise the Option by delivering an exercise notice in a form approved by the Company (the “Exercise Notice”), which shall state the election to exercise the Option, the number of Shares with respect to which the Option is being exercised, and such other representations and agreements as may be required by the Company. The Exercise Notice shall be accompanied by payment of the aggregate Option Price as to all Shares exercised. The Option shall be deemed to be exercised upon receipt by the Company of such fully executed Exercise Notice accompanied by the aggregate Option Price (as well as any applicable withholding or other taxes).

(c)          Acceleration of Exercisability under Certain Circumstances. [Choose (or create a different alternative; e.g., vesting in the event of disability or death): The exercisability of the Option shall not be accelerated under any circumstances, except as otherwise provided in the Plan. / The exercisability of the Option shall not be accelerated under any circumstances, except as otherwise provided in the Plan; provided, however, that the Option shall become fully exercisable immediately prior to, and contingent upon, a Change in Control.]

3.          Method of Payment. If the Grantee elects to exercise the Option by submitting an Exercise Notice in accordance with Section 2(b) above, the aggregate Option Price (as well as any applicable withholding or other taxes) shall be paid by cash or check; provided, however, that the Committee may, but is not required to, consent to payment in any of the following forms, or a combination of them:

(a)          cash or check;

(b)          a “net exercise” under which the Company reduces the number of Shares issued upon exercise by the largest whole number of Shares with a Fair Market Value that does not exceed the aggregate Option Price and any applicable withholding, or such other consideration received by the Company under a cashless exercise program approved by the Company in connection with the Plan;

(c)          surrender of other Shares owned by the Grantee that have a Fair Market Value on the date of surrender equal to the aggregate Option Price of the exercised Shares and any applicable withholding; or

(d)          any other consideration that the Committee deems appropriate and in compliance with applicable law.

4.          Restrictions on Exercise.
