Exercise of SARs. A SAR may be exercised to the extent that the Option in which it is included is exercisable, subject to any restrictions imposed by Rule 16b-3 under the Exchange Act (as amended from time to time). If, on the date when an Option expires, the Exercise Price under such Option is less than the Fair Market Value on such date but any portion of such Option has not been exercised or surrendered, then any SAR included in such Option shall automatically be deemed to be exercised as of such date with respect to such portion. An Option granted under the Plan may provide that it will be exercisable as a SAR only in the event of a Change in Control.

Exercise of SARs. Unless the Award Agreement otherwise provides, an SAR related to an Option will be exercisable at such time or times, and to the extent, that the related Option will be exercisable; provided that the Award Agreement shall not, without the approval of the stockholders of the Company, provide for a vesting period for the exercise of the SAR that is more favorable to the Participant than the exercise period for the related Option. An SAR may not have a term exceeding eight years from its Grant Date. An SAR granted independently of any other Award will be exercisable pursuant to the terms of the Award Agreement. Whether an SAR is related to an Option or is granted independently, the SAR may only be exercised when the Fair Market Value of the Shares underlying the SAR exceeds the exercise price of the SAR.
