Once this Option has become exercisable with respect to any portion of the total number of shares in accordance with the preceding sentence, it shall continue to be exercisable with respect to such shares until the termination of Optionee’s rights hereunder pursuant to paragraphs 4, 5 or 6, or until the Expiration Date. A partial exercise of this Option shall not affect Optionee’s right to exercise subsequently this Option with respect to the remaining shares that are exercisable, subject to the conditions of the 2007 Stock Incentive Plan (Plan) and this Agreement.

2. Method of Exercising and Payment for Shares . This Option may be exercised only by written notice delivered to the attention of the Company’s Secretary at the Company’s principal office. The written notice shall specify the number of shares being acquired pursuant to the exercise of the Option when such Option is being exercised in part in accordance with the Vesting Schedule. The exercise date shall be the date such notice is received by the Company. Such notice shall be accompanied by payment of the Option price in full for each share (a) in cash (United States dollars) or by cash equivalent acceptable to the Company, or (b) by a cashless exercise pursuant to Section IX(2) of the Plan.
