Exercise. The Option Holder (or in the case of the death of the Option Holder, the designated legal representative or heir of the Option Holder) may exercise the NQSOs during the Exercise Period by giving written notice to the ​ in the form required by the Committee (“Exercise Notice”). The Exercise Notice must specify the number of Shares to be purchased, which shall be at least 100 unless fewer shares remain unexercised. The exercise date is the date the Exercise Notice is received by the Company. The Exercise Period commences on the Vesting Date and expires at 5:00 p.m., Pacific Time, on the date 10 years after the Grant Date, such later time and date being hereinafter referred to as the “Expiration Date,” subject to earlier expiration in the event of a termination of Service as provided in Section 5. Any NQSOs not exercised as of the close of business on the last day of the Exercise Period shall be cancelled without consideration at that time.

With respect to the Company’s establishment of an exercise window, # any exercise of an Option or SAR during the fifteen (15)-day period referred above shall be conditioned upon the consummation of the applicable Change in Control and shall be effective only immediately before the consummation thereof, and # upon consummation of any Change in Control, the Plan and all outstanding but unexercised Options and SARs shall terminate. The Committee shall send notice of an event that shall result in such termination to all Participants or Permitted Transferees who hold Options and SARs not later than the time at which the Company gives notice thereof to its shareholders.

If the Participant uses cash to exercise this option and purchase shares, rather than a cashless exercise method, the Participant must first obtain a “Tax Clearance Certificate (in Respect of Foreign Investment)” from the South African Reserve Service ("SARS"). The Participant must renew this Tax Clearance Certificate every twelve months, or such other period as may be required by SARS. The Participant must also complete a transfer of funds application form to transfer the funds. The Tax Clearance Certificate should be presented to a dealer of the Exchange Control Department of the South Africa Reserve Bank (it is likely that the Participant’s bank will qualify as such a dealer), together with a completed application form to transfer funds. No transfer of funds may be completed unless the original Tax Clearance Certificate bears the official stamp and signature of the Office of Receiver of Revenue of SARS.

SARs Related to Options. The Committee may grant SARs either concurrently with the grant of an Option or with respect to an outstanding Option, in which case the SAR shall extend to all or a portion of the Shares covered by the related Option. An SAR shall entitle the Participant who holds the related Option, upon exercise of the SAR and surrender of the related Option, or portion thereof, to the extent the SAR and related Option each were previously unexercised, to receive payment of an amount determined pursuant to Sections 7(e) and 7(f). Any SAR granted in connection with an ISO will contain such terms as may be required to comply with the provisions of Section 422 of the Code and the regulations promulgated thereunder.

SARs Independent of Options. The Committee may grant SARs that are independent of any Option subject to such conditions as the Committee may in its discretion determine, which conditions will be set forth in the applicable Award Agreement.

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.

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.

Holders of SARs which have not yet vested are not entitled to receive dividends, however, dividends may be accrued and paid upon the vesting of such SARs. The Administrator may provide that any dividends paid on SARs must be reinvested in shares of Stock, which may or may not be subject to the same vesting conditions and restrictions applicable to such SARs. All distributions, if any, received by a Grantee with respect to SARs as a result of any stock split, stock dividend, combination of shares, or other similar transaction shall be subject to the restrictions applicable to the original Award.
