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.

Exercise of SARs. SARs may be exercised by delivery to the Company of a notice of exercise in a form (which may be electronic) approved by the Company, together with any other documents required by the Board.

Exercise of SARs. Upon exercise of a SAR, the Participant (or any person having the right to exercise the SAR after such Participant’s death) shall receive from the Company # Shares, # cash or # a combination of Shares and cash, as the Committee shall determine. The amount of cash and/or the Fair Market Value of Shares received upon exercise of a SAR shall, in the aggregate, be equal to the amount by which the Fair Market Value (on the date of surrender) of the Shares subject to the SAR exceeds the Exercise Price.

Exercise of SARs. SARs shall be exercised by the delivery of a written notice of exercise to the Company or its designee, setting forth the number of Shares over which the SAR is to be exercised. Tandem SARs # may be exercised with respect to all or part of the Shares subject to the related Option upon the surrender of the right to exercise the equivalent portion of the related Option; # may be exercised only with respect to the Shares for which its related Option is then exercisable; and # may be exercised only when the Fair Market Value of the Shares subject to the Option exceeds the Option Price of the Option. The value of the payment with respect to the Tandem SAR may be no more than 100% of the difference between the Option Price of the underlying Option and the Fair Market Value of the Shares subject to the underlying Option at the time the Tandem SAR is exercised.

Exercise of SARs. SARs may be exercised upon whatever terms and conditions the Committee, in its sole discretion, imposes upon the SARs.

Stock Options and SARs. Upon a Change in Control, each outstanding Option and SAR shall be assumed or an equivalent option or stock appreciation right shall be substituted by the successor corporation or a Parent or Subsidiary of the successor corporation. Unless determined otherwise by the Administrator, if the successor corporation refuses to assume or substitute for the Option or SAR, such Option or SAR shall fully vest, and the Participant shall have the right to exercise the Option or SAR as to all of the Awarded Stock, including Shares as to which the Option or SAR would not otherwise be vested or exercisable. If an Option or SAR is not assumed or substituted for upon the Change in Control, the Administrator shall notify the Participant in writing or electronically that the Option or SAR shall be exercisable for a period of at least ninety (90) days prior to the Change in Control (any such exercise being subject in all events to the consummation of such Change in Control), and the Option or SAR shall terminate upon the occurrence of the Change in Control. For the purposes of this [Section 16(c)(i)], the Option or SAR

Vesting Period: Ratably over four (4) years, with twenty-five percent (25%) becoming exercisable on each of the first, second, third and fourth anniversary of the grant date, except as provided in the Plan.

Section # Prohibition on Repricing SARs. Except as permitted under Section 4.04 of the Plan, the terms of any outstanding SAR may not be amended without shareholder approval to reduce the Exercise Price of such outstanding SAR or to cancel such outstanding SAR in exchange for cash, other Awards, or an Option or SAR with an exercise price that is less than the Exercise Price of the original SAR.

The Exercise Price is, for Options, the value of the consideration that a participant must provide in exchange for one share of Common Stock and, for SARs, the measurement price. The Administrator will determine the Exercise Price under each Award and may set the Exercise Price without regard to the Exercise Price of any other Awards granted at the same or any other time. The Company may use the consideration it receives from the participant for general corporate purposes.

"SAR" means a stock appreciation right and includes both Tandem SARs and Freestanding SARs.

Section # Settlement of SARs. Upon exercise of a SAR, the Participant shall be entitled to receive payment in Shares, or such other form as determined by the Administrator, having an aggregate value equal to the Fair Market Value of one Share on the exercise date over # the Base Price of such SAR; provided, however, that on the grant date, the Administrator may establish a maximum amount per Share that may be payable upon exercise of a SAR.

Incapacity. Options and SARs shall be exercisable during a Participant’s lifetime only by the Participant; provided, however, that in the event a Participant is incapacitated and unable to exercise his or her Options or SARs, such Awards may be exercised by the Participant’s legal guardian, legal representative or other representative if the Committee deems such representative appropriate based on applicable facts and circumstances. The determination of incapacity of a Participant and the determination of an incapacitated Participant’s appropriate representative shall be made by the Committee in its sole discretion.

shares withheld by, or otherwise remitted to, the Company to satisfy a Participant's tax withholding obligations upon the lapse of restrictions on a Stock Award or the exercise of any Options or SARs granted under the Plan or upon any other payment or issuance of shares under the Plan.

Upon the exercise of a Stock Appreciation Right, a Participant shall be entitled to receive an amount in cash or shares of Stock, as determined by the Committee at the time of grant, equal in value to the excess of the Fair Market Value of one share of Stock on the date of exercise of the Stock Appreciation Right over # the Option Exercise Price specified in the related Stock Option in the case of Tandem SARs, which price shall be fixed no later than the date of grant of the Tandem SARs, or # the price per share specified in the related Award Agreement in the case of Freestanding SARs, which price shall be fixed at the date of grant and shall be not less than the Fair Market Value of the Stock on the date of grant, multiplied by the number of shares of Stock in respect of which the Stock Appreciation Right shall have been exercised. The Committee shall have the right to approve or refuse to approve any election by the Participant to receive cash, in whole or in part, upon exercise of the Stock Appreciation Right. When payment is to be made in Stock, the number of shares of Stock to be paid shall be calculated on the basis of the Fair Market Value of the Stock on the date of exercise. Notwithstanding the foregoing, the Committee may unilaterally limit the appreciation in value of any Stock Appreciation Right at any time prior to exercise.

amend the terms of any outstanding Award, including the discretionary authority to extend the post‑termination exercise period of Awards and accelerate the satisfaction of any vesting criteria or waiver of forfeiture or repurchase restrictions, provided that any amendment that would adversely affect the Participant’s rights under an outstanding Award shall not be made without the Participant’s written consent; provided, however, that except as otherwise provided in [Section 16], the Administrator shall not, without prior approval of the Company’s stockholders # amend the exercise price of outstanding Options or SARs, # cancel and re-grant Options or SARs at a lower exercise price, or # substitute underwater Options for other securities (including buyouts through issuance of such cash or other means). Notwithstanding the foregoing, an amendment shall not be treated as adversely affecting the rights of the Participant if the amendment causes an Incentive Stock Option to become a Non-statutory Stock Option or if the amendment is made to the minimum extent necessary to avoid the adverse tax consequences of Section 409A of the Code;
