(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) Notwithstanding any provision of the Agreement to the contrary, if the Optionee resides and/or works outside of the United States, the Company may require that the Optionee exercise the Option in a method other than specified above, may require the Optionee to exercise the Option only by means of a “same day sale” transaction (either a sell-all transaction or a sell-to-cover transaction) as it determines in its sole discretion, or may require the Optionee to sell any Shares he or she acquires under the Plan immediately or within a specified period following the termination of the Optionee’s employment or service with the Company or any Subsidiary (in which case, the Optionee hereby agrees that the Company shall have the authority to issue sale instructions in relation to such Shares on the Optionee’s behalf). Section 2.9 Change in Control. In the event of a Change in Control prior to the Vesting Date, notwithstanding anything in Article XIII of the Plan to the contrary, any unvested Options shall remain outstanding and shall vest on the applicable Vesting Date, subject to the continued employment or service of the Participant by the Company or any Subsidiary thereof through such date; provided, that, if the Participant’s employment or service is terminated by the Company without Cause or for Good Reason

5 (each, a “Qualifying CIC Termination”) within two (2) years following the effective date of the Change in Control, such outstanding Options shall vest as of the date of such Qualifying CIC Termination. For purposes of this Agreement, “Good Reason” means (i) if a Participant is a party to an employment or service agreement with the Company and such agreement provides for a definition of Good Reason, the definition contained therein; or (ii) if no such agreement exists or if such agreement does not define Good Reason, the occurrence of one or more of the following without the Participant’s express written consent, which circumstances are not remedied by the Company within thirty (30) days of its receipt of a written notice from the Participant describing the applicable circumstances (which notice must be provided by the Participant within ninety (90) days of the Participant’s knowledge of the applicable circumstances): (A) any material, adverse change in the Participant’s duties, responsibilities or authority; (B) a material reduction in the Participant’s base salary or bonus opportunity; or (C) a geographical relocation of the Participant’s principal office location by more than fifty (50) miles (other than a temporary geographical relocation for business reasons).

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. ARTICLE III. OTHER PROVISIONS Section 3.1 Tax Withholding. The Optionee acknowledges that, regardless of any action taken by the Company or, if different, the Optionee’s employer (the “Employer”) with respect to any or all income tax (including U.S. federal, state and local taxes and/or non-U.S. taxes), social insurance, payroll tax, fringe benefits tax, payment on account or other tax-related items related to the Optionee’s participation in the Plan and legally applicable to the Optionee (“Tax-Related Items”), the ultimate liability for all Tax- Related Items is and remains the Optionee’s personal responsibility and may exceed the amount, if any, actually withheld by the Company or the Employer. The Optionee further acknowledges that the Company and/or the Employer (a) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the Optionee’s participation in the Plan, including, but not limited to, the grant of Option, the vesting of Option, the exercise of Option, the issuance or sale of Shares, or the receipt of any dividends; and (b) do not commit to and are under no obligation to structure the terms of the Option or any aspect of the Plan to reduce or eliminate the Optionee’s liability for Tax-Related Items or achieve any particular tax result. Further, if the Optionee is subject to Tax- Related Items in more than one jurisdiction, the Optionee acknowledges that the Company and/or the Employer (or former employer, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction. Prior to any relevant taxable or tax withholding event, as applicable, the Optionee agrees to make arrangements satisfactory to the Company and/or the Employer to satisfy all Tax-Related Items. In this regard, the Optionee authorizes the Company and/or the Employer, or their respective agents, at their discretion, to satisfy their withholding obligations with regard to any Tax-Related Items by one or a combination of the following: (a) withholding from the Optionee’s wages or other cash compensation

6 payable to the Optionee by the Company and/or the Employer, (b) withholding from proceeds of the sale of Shares under the Plan, either through a voluntary sale or through a mandatory sale arranged by the Company (on the Optionee’s behalf pursuant to this authorization without further consent) to cover the Tax-Related Items required to be withheld, and (c) withholding in Shares to be issued upon exercise of the Options. If the obligation for Tax-Related Items is satisfied by withholding in Shares, for tax purposes, the Optionee will be deemed to have been issued the full number of Shares, notwithstanding that a number of the Shares are held back solely for the purpose of paying the Tax-Related Items. Section 3.2 Nature of Grant.

7 (l) no claim or entitlement to compensation or damages shall arise from forfeiture of the Option or recoupment of any Shares acquired under the Plan resulting from (1) termination of the Optionee’s employment (regardless of the reason for the termination and whether or not the termination is later found to be invalid or in breach of employment laws in the jurisdiction where the Optionee is employed or the terms of the Optionee’s employment or service agreement, if any) and/or (2) the application of any recoupment policy or any recovery or clawback policy otherwise required by law; and (m) neither the Company, the Employer nor any other Subsidiary shall be liable for any foreign exchange rate fluctuation between the Optionee’s local currency and the United States Dollar that may affect the value of the Shares or any amounts due pursuant to the issuance of the Shares, or the subsequent sale of any Shares acquired under the Plan.
