Section # Exercisability and Vesting; Exercise. Each Option and SAR shall vest and become exercisable according to the terms and conditions as determined by the Administrator. Except as otherwise determined by the Administrator, Options and SARs shall vest ratably in equal annual installments over a three-year period, on each of the first three anniversaries of the grant date. Except as otherwise determined by the Administrator, SARs granted in tandem with an Option shall become vested and exercisable on the same date or dates as the Options with which such SARs are associated vest and become exercisable. SARs that are granted in tandem with an Option may only be exercised upon the surrender of the right to exercise such Option for an equivalent number of Shares, and may be exercised only with respect to the Shares for which the related Option is then exercisable. The Administrator shall specify the manner of and any terms and conditions of exercise of an exercisable Option or SAR, including but not limited to net-settlement, delivery of previously owned stock and broker-assisted sales.

Stock Appreciation Rights. Subject to the terms of this Plan, the Administrator will determine all terms and conditions of each SAR, including but not limited to: # whether the SAR is granted independently of an Option or relates to an Option; # the grant date, which may not be any day prior to the date that the Administrator approves the grant; # the number of Shares to which the SAR relates; # the grant price, provided that the grant price shall not be less than the Fair Market Value of the Shares subject to the SAR as determined on the date of grant; # the terms and conditions of exercise or maturity, including vesting; # the term, provided that an SAR must terminate no later than ten (10) years after the date of grant; and # whether the SAR will be settled in cash, Shares or a combination thereof. If an SAR is granted in relation to an Option, then unless otherwise determined by the Administrator, the SAR shall be exercisable or shall mature at the same time or times, on the same conditions and to the extent and in the proportion, that the related Option is exercisable and may be exercised or mature for all or part of the Shares subject to the related Option. Upon exercise of any number of SARs, the number of Shares subject to the related Option shall be reduced accordingly and such Option may not be exercised with respect to that number of Shares. The exercise of any number of Options that relate to an SAR shall likewise result in an equivalent reduction in the number of Shares covered by the related SAR.

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.
