(d)    Withholding Taxes.    As a condition to the exercise of an Option, the Optionee shall make such arrangements as the Board may require for the satisfaction of any federal, state, local or foreign 


2











withholding tax obligations that may arise in connection with such exercise. The Optionee shall also make such arrangements as the Board 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. The vesting of any Option shall be determined by the Board on the date of grant at its sole discretion. A Stock Option Agreement may provide for accelerated exercisability in the event of the Optionee’s death, disability or retirement or other events, and the Board shall have the power to accelerate the exercisability of any outstanding Option.



(f)    Term.    The Stock Option Agreement shall specify the term of the Option. The term shall not exceed 10 years from the date of grant. Subject to the preceding sentence, the Board at its sole discretion shall determine the expiration date of an Option on the date of grant.



(g)    Transferability of Options.    No Option shall be transferable except by will or the laws of descent and distribution; provided, however, subject to Section 6(k) hereof, Options may be transferred to the Optionee’s estate, spouse, ancestors, lineal descendants and siblings or any trusts for the benefit of such Optionee or the foregoing persons or charitable foundations or trusts controlled by such Optionee.



(h)    Termination of Service.    If an Optionee’s Service terminates for any reason, then his or her Options shall expire on the expiration date set forth in his or her Stock Option Agreement. The Optionee may exercise all or part of his or her Options at any time before the expiration of such Options under the preceding sentence, but only to the extent that such Options had become vested and exercisable before his or her Service terminated or became vested and exercisable as a result of the termination. The balance of such unvested Options shall lapse when the Optionee’s Service terminates.



(i)    No Rights as a Shareholder.    An Optionee, or a transferee of an Optionee, shall have no rights as a shareholder with respect to any Shares covered by his or her Option until the date of the issuance of a stock certificate for such Shares.



(j)    Modification, Extension and Assumption of Options.    Within the limitations of the Plan, the Board may modify, extend or assume outstanding Options, including the Exercise Price thereof, 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. The foregoing notwithstanding, no modification of an Option shall, without the consent of the Optionee, impair his or her obligations under such Option.



(k)    Restrictions on Transfer of Shares.    Any Options and any Shares issued upon exercise of an Option may be subject to such special forfeiture conditions, rights of repurchase and/or puts, rights of first refusal and other transfer restrictions as may be set forth in the Shareholders Agreement. Such restrictions may be set forth and referred to in the applicable Stock Option Agreement and shall apply in addition to any restrictions that may apply to holders of Options or Shares generally.



SECTION 7.    PAYMENT FOR SHARES.



(a)    General Rule.    The Optionee may pay for the Shares to be issued on exercise of the Option in a combination of any of the methods outlined in Subsections (b), (c), or (d) below equal in value to the aggregate Exercise Price for the Shares.



(b)    Legal Currency.    The entire Exercise Price of Shares issued under the Plan may be paid in lawful money of the United States of America at the time when such Shares are purchased.



(c)    Surrender of Stock.    Payment of the Shares may be made in whole or in part with Shares which have already been owned by the Optionee or his or her representative for at least six months and which are surrendered to the Company in good form for transfer with Shares withheld from the Shares otherwise deliverable to the Optionee upon exercise of the Option. Such Shares shall be valued at their Fair Market Value on the date when the Option is exercised.


3










(d)    Stock Withholding.    The Optionee may pay for the Shares by providing written direction to the Company to withhold from the number of Shares to be issued on exercise of the Option a number of Shares having a Fair Market Value equal to the aggregate Exercise Price for such Shares. In addition, to the extent that a Stock Option Agreement so provides, any tax withholding obligation attendant to the exercise of an Option may be satisfied by the Company or the Optionee’s employer withholding Shares otherwise deliverable to the Optionee.



SECTION 8.    ADJUSTMENT OF SHARES.



(a)    General.    In the event of a stock split, a declaration of a dividend payment 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 or a reclassification, or a change in the Shares as a result of a merger or reorganization or a similar occurrence, the Board shall make appropriate adjustments in one or more of (i) the number of Shares available for grants under Section 5, (ii) the number of Shares covered by each outstanding Option or (iii) the Exercise Price under each outstanding Option, so that the Plan and Options remain substantially the same as before such change.



(b)    Reservation of Rights.    Except as provided in this Section 8, an Optionee shall have no rights by reason of (i) any subdivision or consolidation of shares of stock of any class, (ii) the payment of any dividend or (iii) any other increase or decrease in the number of shares of stock of any class. 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 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 9.    LEGAL REQUIREMENTS.



(a)    Transfer Restrictions.    Appropriate legends may be placed on the stock certificates evidencing shares issued upon exercise of Options to reflect transfer restrictions.



(b)    Board Discretion.    Any Option granted under the Plan is subject to the requirement that if at any time the Board determines, in its discretion, that the listing, registration or qualification of Shares issuable upon exercise of Options is required by any securities exchange or under any state or Federal law, or that the consent or approval of any governmental regulatory body is necessary or desirable as a condition of, or in connection with, the grant of options or the issuance of Shares, no Shares shall be issued, in whole or in part, unless such listing, registration, qualification, consent or approval has been effected or obtained free of any conditions or with such conditions as are acceptable to the Board.



SECTION 10.    NO EMPLOYMENT RIGHTS.



No provision of the Plan, nor any right or Option granted under the Plan, shall be construed to give any person any right to become, to be treated as, or to remain an Employee. The Company and its Subsidiaries reserve the right to terminate any person’s Service at any time and for any reason.

(c)    Effect of Amendment or Termination.    No Shares shall be issued or sold under the Plan after the termination thereof, except upon exercise of an Option granted prior to such termination. The termination of the Plan, or any amendment thereof, shall not affect any Share previously issued or any Option previously granted under the Plan.
