The Optionee shall also make such arrangements as the Committee may require for the satisfaction of any federal, state, local or foreign withholding tax obligations that may arise in connection with the disposition of Shares acquired by exercising an Option.

(e) Exercisability. Each Stock Option Agreement shall specify the date when all or any installment of the Option is to become exercisable. To the extent required by applicable law, an Option shall become exercisable no less rapidly than the rate of twenty percent (20%) per year for each of the first five years from the date of grant. Subject to the preceding sentence, the vesting of any Option shall be determined by the Committee in its sole discretion.

(f) Term. The Stock Option Agreement shall specify the term of the Option. The term shall not exceed ten (10) years from the date of grant, except as otherwise provided in Section 4(b). Subject to the preceding sentence, the Committee at its sole discretion shall determine when an Option is to expire.

(g) Nontransferability. No Option shall be transferable by the Optionee other than by will or by the laws of descent and distribution. An Option may be exercised during the lifetime of the Optionee only by the guardian or legal representative of the Optionee. No Option or interest therein may be transferred, assigned, pledged or hypothecated by the Optionee during his/her lifetime, whether by operation of law or otherwise, or be made subject to execution, attachment or similar process.

(h) Exercise of Options on Termination of Service. Each Stock Option Agreement shall set forth the extent to which the Optionee shall have the right to exercise the Option following termination of the Optionee’s service with the Company and its Subsidiaries. Such provisions shall be determined in the sole discretion of the Committee, need not be uniform among all Options issued pursuant to the Plan, and may reflect distinctions based on the reasons for termination of employment. Notwithstanding the foregoing, to the extent required by applicable law, each Option shall provide that the Optionee shall have the right to exercise the vested portion of any Option held at termination for at least thirty (30) days following

-6-

termination of service with the Company for any reason, and that the Optionee shall have the right to exercise the Option for at least six months if the Optionee’s service terminates due to death or Disability.

(j) Modification, Extension and Assumption of Options. Within the limitations of the Plan, the Committee may modify, extend or assume outstanding Options or may accept the cancellation of outstanding Options (whether granted by the Company or another issuer) in return for the grant of new Options for the same or a different number of Shares and at the same or a different Exercise Price.

(k) Restrictions on Transfer of Shares. No Shares issued upon exercise of an Option may be sold or otherwise transferred or disposed of by the Optionee during the one hundred eighty (180) day period following the effective date of a registration statement covering securities of the Company filed under the Securities Act of 1933. Subject to the preceding sentence, any Shares issued upon exercise of an Option shall be subject to such rights of repurchase, rights of first refusal and other transfer restrictions as the Committee may determine. Such restrictions shall be set forth in the applicable Stock Option Agreement and shall apply in addition to any restrictions that may apply to holders of Shares generally.

SECTION 8. PAYMENT FOR SHARES.

(a) General Rule. The entire Exercise Price or Purchase Price, as applicable, of Shares issued under the Plan shall be payable in lawful money of the United States of America at the time when such Shares are purchased, except as provided in Subsection (b) below.

SECTION 9. ADJUSTMENT OF SHARES.

(a) General. In the event of a subdivision of the outstanding Stock, a declaration of a dividend payable in Shares, a declaration of a dividend payable in a form other than Shares in an amount that has a material effect on the value of Shares, a combination or consolidation of the outstanding Stock into a lesser number of Shares, a recapitalization, a reclassification or a similar occurrence, the Committee shall make appropriate adjustments in one or more of (i) the number of Shares available for future grants of Options or other rights to acquire Shares under Section 5, (ii) the number of Shares covered by each outstanding Option or other right to acquire Shares or (iii) the Exercise Price of each outstanding Option or the Purchase Price of each other right to acquire Shares.

Any issue by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall not affect, and no adjustment by reason thereof shall be made with respect to, the number or Exercise Price of Shares subject to an Option, or the number or Purchase Price of shares subject to any other right to acquire Shares. The grant of an Option or other right to acquire Shares pursuant to the Plan shall not affect in any way the right or power of the Company to make adjustments, reclassifications, reorganizations or changes of its capital or business structure, to merge or consolidate or to dissolve, liquidate, sell or transfer all or any part of its business or assets.

SECTION 10. LEGAL REQUIREMENTS.
