Section 2.7    Exercise of Option. The exercise of the Option shall be governed by the terms of this Agreement and the terms of the Plan, including, without limitation, the provisions of Article V of the Plan.

Section 2.8    Manner of Exercise; Tax Withholding.

(a)    As a condition to the exercise of the Option, the Optionee shall (i) notify the Company at least three (3) days prior to exercise and no earlier than ninety (90) days prior to exercise that the Optionee intends to exercise and (ii) provide the Company with payment of the Exercise Price of the Option, together with any Withholding Tax payment required by Section 3.8 below, which shall be payable to the Company in full as set forth in Section 2.8(b) or Section 2.8(c) below, as applicable.

(b)    To the extent permitted by law or the applicable listing rules, if any, the Optionee may pay for the Shares with respect to which such Option or portion of such Option is exercised through (i) payment in cash; (ii) with the consent of the Administrator, the delivery of Shares which are owned by the Optionee, duly endorsed for transfer to the Company with a Fair Market Value on the date of delivery equal to the aggregate Exercise Price of the exercised portion of the Option; (iii) with the consent of the Administrator, through the surrender of Shares then issuable upon exercise of the Option having a Fair Market Value on the date of the exercise of the Option equal to the aggregate Exercise Price of the exercised portion of the Option; or (iv) with the consent of the Administrator, delivery of a notice that the Optionee has placed a market sell order with a broker with respect to Shares then-issuable upon exercise of the Option, and that the broker has been directed to pay a sufficient portion of the net proceeds of the sale to the Company in satisfaction of the aggregate Exercise Price; provided, that payment of such

proceeds is then made to the Company upon settlement of such sale. Notwithstanding the foregoing, the consent of the Administrator shall not be required with respect to clauses (iii) and (iv) of this Section 2.8(b) if the Optionee exercises such Option on or after the date of the Optionee’s Retirement.

(c)    As a condition to exercise, the Optionee must make appropriate arrangements for the payment to the Company (or its Subsidiary, as applicable) in cash or by delivery of a certified or bank cashier check, or by any other means of payment approved by the Administrator, of the amount which the Company (or its Subsidiary, as applicable) is required to withhold under applicable law in connection with the exercise of the Option. With the consent of the Administrator and subject to any applicable legal conditions or restrictions, the Company shall, upon the Optionee’s request, withhold from the Shares issuable to the Optionee upon the exercise of the Option (or any portion thereof) a number of whole Shares having a Fair Market Value, determined as of the date of exercise, not in excess of the minimum of tax required to be withheld by law (or such lower amount as may be necessary to avoid liability award accounting). Any adverse consequences to the Optionee arising in connection with the Share withholding procedure set forth in the preceding sentence shall be the sole responsibility of the Optionee.

Section 2.9    Change in Control. Upon the occurrence of a Change in Control, the Options shall vest, forfeit or continue as set forth in Article XIII of the Plan. At the discretion of the Administrator (as constituted immediately prior to the Change in Control), any or all vested Options may be canceled in exchange for an amount equal to the product of (A) the excess, if any, of the Fair Market Value of the Shares upon the Change in Control over the exercise price for such vested Options, multiplied by (B) the aggregate number of shares of Company Common Stock covered by such vested Options. Payment of any amounts calculated in accordance with this Section 2.9 shall be made in cash or, if determined by the Administrator (as constituted immediately prior to the Change in Control), in shares of common stock of the new employer having an aggregate fair market value equal to such amount or in such securities or other property as are paid to the stockholders of the Company in connection with the Change of Control and shall be payable in full, as soon as reasonably practicable, but in no event later than 30 days, following the Change in Control or such later date as such consideration is paid to the stockholders of the Company generally provided that all such payments shall in all events be payable to the stockholders generally within five years after the Change in Control.

Nothing in this Agreement or in the Plan shall confer upon the Optionee any right to continue as a Service Provider, or shall interfere with or restrict in any way the rights of the Company or its Subsidiaries, which are hereby expressly reserved, to discharge the Optionee at any time for any reason whatsoever, with or without Cause, except to the extent expressly provided otherwise in a written employment or other agreement between the Optionee and the Company or any of its Subsidiaries.

Section 3.7    Data Privacy Consent. As a condition of the Option grant if the Optionee is a Non-U.S. Optionee, the Optionee explicitly and unambiguously consents to the collection, use and transfer, in electronic or other form, of personal data as described in this paragraph by and among, as applicable, the Company and its Subsidiaries and Affiliates for the exclusive purpose of implementing, administering and managing the Optionee’s participation in the Plan.

The Optionee understands that he or she may request a list with the names and addresses of any potential recipients of the Data by contacting his or her local human resources representative. The Optionee authorizes such recipients to receive, possess, use, retain and transfer the Data, in electronic or other form, for the purposes of implementing, administering and managing the Optionee’s participation in the Plan, including any requisite transfer of such Data as may be required to a broker or other third party with whom the Optionee may elect to deposit any Shares. The Optionee understands that the Data will be held only as long as is necessary to implement, administer, and manage the Optionee’s participation in the Plan. The Optionee understands that he or she may, at any time, view the Data, request additional information about the storage and processing of the Data, require any necessary amendments to the Data, or refuse or withdraw the consents herein in writing, in any case without cost, by contacting his or her local human resources representative. The Optionee understands that refusal or withdrawal of consent may affect the Optionee’s ability to participate in the Plan. For more information on the consequences of refusal to consent or withdrawal of consent, the Optionee understands that he or she may contact his or her local human resources representative.

Section 3.8    Withholding Taxes.

The Optionee shall be responsible for all Withholding Taxes and other tax consequences of this Award.

Section 3.9    Electronic Delivery. The Company may, in its sole discretion, decide to deliver any documents related to any Option granted under the Plan by electronic means or request the Optionee’s consent to participate in the Plan by electronic means.

maintained by the Company or another third party designated by the Company, and such consent shall remain in effect throughout the Optionee’s term of employment or service with the Company and thereafter until withdrawn in writing by the Optionee.
