Such Option shall be subject to all applicable terms and conditions of the Plan and may be subject to any other terms and conditions that are not inconsistent with the Plan and that the Committee deems appropriate for inclusion in a Stock Option Agreement (including without limitation any performance conditions).

(c) Exercise Price. An Option’s Exercise Price shall be established by the Committee and set forth in a Stock Option Agreement.

(d) Exercisability and Term. Each Stock Option Agreement shall specify the date when all or any installment of the Option is to become exercisable. The Stock Option Agreement shall also specify the term of the Option; provided that the term of an Option shall in no event exceed nine years from the date of grant. Unless the applicable Stock Option Agreement provides otherwise, each Option shall vest and become exercisable with respect to 20% of the Shares subject to the Option upon completion of one year of Service measured from the vesting commencement date, the balance of the Shares subject to the Option shall vest and become exercisable in forty-eight equal installments upon completion of each month of Service thereafter, and the term of the Option shall be nine years from the date of grant. A Stock Option Agreement may provide for accelerated vesting in the event of the Participant’s death, Disability, or other events. Notwithstanding any other provision of the Plan, no Option can be exercised after the expiration date provided in the applicable Stock Option Agreement and no Option may provide that, upon exercise of the Option, a new Option will automatically be granted.

SECTION 7. PAYMENT FOR OPTION SHARES.

The entire Exercise Price of Shares issued upon exercise of Options shall be payable in cash at the time when such Shares are purchased, except as follows and only if so provided for in an applicable Stock Option Agreement:

(i) Surrender of Stock. Payment for all or any part of the Exercise Price may be made with Shares which have already been owned by the Optionee; provided that the Committee may, in its sole discretion, require that Shares tendered for payment be previously held by the Optionee for a minimum duration. Such Shares shall be valued at their Fair Market Value.

vi

(ii) Cashless Exercise. Payment for all or any part of the Exercise Price may be made through Cashless Exercise.

(iii) Other Forms of Payment. Payment for all or any part of the Exercise Price may be made in any other form that is consistent with applicable laws, regulations and rules and approved by the Committee.

SECTION 8. PROTECTION AGAINST DILUTION.

(a) Adjustments. In the event of a subdivision of the outstanding Shares, 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 price of Shares, a combination or consolidation of the outstanding Shares (by reclassification or otherwise) into a lesser number of Shares, a recapitalization, a spin-off or a similar occurrence, the Committee shall make appropriate adjustments to the following:

(i) the number of Shares and the kind of shares or securities available for future Options under Section 5;

(iii) the Exercise Price under each outstanding Option.

If by reason of an adjustment pursuant to this Section 8 a Participant’s Option covers additional or different shares of stock or securities, then such additional or different shares and the Option in respect thereof shall be subject to all of the terms, conditions and restrictions which were applicable to the Option and the Shares subject to the Option prior to such adjustment.

(c) Fractional Shares. Any adjustment of Shares pursuant to this Section 8 shall be rounded down to the nearest whole number of Shares. Under no circumstances shall the Company be required to authorize or issue fractional shares and no consideration shall be provided as a result of any fractional shares not being issued or authorized.

SECTION 9. EFFECT OF A CORPORATE TRANSACTION.

(a) Corporate Transaction. In the event that the Company is a party to a Corporate Transaction, outstanding Options shall be subject to the applicable agreement of merger, reorganization, or sale of assets. Such agreement may provide, without limitation, for the assumption or substitution of outstanding Options by the surviving corporation or its parent, or for the cancellation of outstanding Options, with or without consideration, in all cases without the consent of the Participant.

(b) Acceleration. The Committee may determine, at the time of grant of an Option or thereafter, that such Option shall become fully vested as to all Shares subject to such Option in the event that a Corporate

vii

Transaction or a Change in Control occurs. Unless otherwise provided in the applicable Stock Option Agreement, in the event that a Corporate Transaction occurs and any outstanding Options are not assumed, substituted, or replaced, then such Options shall terminate and cease to be outstanding.

(c) Dissolution. To the extent not previously exercised or settled, Options shall terminate immediately prior to the dissolution or liquidation of the Company.

SECTION 10. LIMITATIONS ON RIGHTS.

(a) No Entitlements. A Participant’s rights, if any, in respect of or in connection with any Option is derived solely from the discretionary decision of the Company to permit the individual to participate in the Plan and to benefit from a discretionary Option. By accepting an Option under the Plan, a Participant expressly acknowledges that there is no obligation on the part of the Company to continue the Plan and/or grant any additional Options. Any Option granted hereunder is not intended to be compensation of a continuing or recurring nature, or part of a Participant’s normal or expected compensation, and in no way represents any portion of a Participant’s salary, compensation, or other remuneration for purposes of pension benefits, severance, redundancy, resignation or any other purpose.

Neither the Plan nor any Option granted under the Plan shall be deemed to give any individual a right to remain an employee, consultant or director of the Company, a Parent, a Subsidiary or an Affiliate. The Company and its Parents and Subsidiaries and Affiliates reserve the right to terminate the Service of any person at any time, and for any reason, subject to applicable laws, the Company’s Articles of Incorporation and Bylaws and a written employment agreement (if any), and such terminated person shall be deemed irrevocably to have waived any claim to damages or specific performance for breach of contract or dismissal, compensation for loss of office, tort or otherwise with respect to the Plan or any outstanding Option that is forfeited and/or is terminated by its terms or to any future Option.

(b) Shareholders’ Rights. A Participant shall have no dividend rights, voting rights or other rights as a shareholder with respect to any Shares covered by his or her Option prior to the issuance of such Shares (as evidenced by an appropriate entry on the books of the Company or a duly authorized transfer agent of the Company). No adjustment shall be made for cash dividends or other rights for which the record date is prior to the date when such Shares are issued, except as expressly provided in Section 8.

(c) Regulatory Requirements. Any other provision of the Plan notwithstanding, the obligation of the Company to issue Shares or other securities under the Plan shall be subject to all applicable laws, rules and regulations and such approval by any regulatory body as may be required. The Company reserves the right to restrict, in whole or in part, the delivery of Shares or other securities pursuant to any Option prior to the satisfaction of all legal requirements relating to the issuance of such Shares or other securities, to their registration, qualification or listing or to an exemption from registration, qualification or listing.

SECTION 11. WITHHOLDING TAXES.

(a) General. A Participant shall make arrangements satisfactory to the Company for the satisfaction of any withholding tax obligations that arise in connection with his or her Option. The Company shall not be required to issue any Shares or make any cash payment under the Plan until such obligations are satisfied.

(b) Share Withholding. If a public market for the Company’s Shares exists, the Committee may permit a Participant to satisfy all or part of his or her withholding or income tax obligations by having the Company withhold all or a portion of any Shares that otherwise would be issued to him or her or by surrendering or attesting to all or a portion of any Shares that he or she previously acquired. Such Shares shall be valued based on the value of the actual trade or, if there is none, the Fair Market Value as of the previous day. Any payment of taxes by assigning Shares to the Company may be subject to restrictions, including, but not limited to, any restrictions required by rules of the SEC. The Committee may, in its discretion, also permit a Participant to satisfy withholding or income tax obligations related to an Option through Cashless Exercise or through a sale of Shares underlying the Option.

An amendment of the Plan shall be subject to the approval of the Company’s shareholders only to the extent such approval is otherwise required by applicable laws, regulations or rules.
