One Common Share will be issued by the Company for each RSU that is vested on:

Issuance of Shares. Upon exercise of the Options and payment of the Exercise Price for the Shares as to which the Options are exercised and satisfaction of all applicable tax withholding requirements, if any, the Company shall issue to Participant the applicable number of Shares in the form of fully paid and nonassessable Shares.

Exercise of Options. Options may be exercised by delivery to the Company of a notice of exercise in a form of notice (which may be electronic) approved by the Company, together with payment in full (in a manner specified in Section 5(f)) of the exercise price for the number of shares for which the Option is exercised. Shares of Common Stock subject to the Option will be delivered by the Company as soon as practicable following exercise.

Subject to the provisions of Section 5 hereof, an option granted hereunder may not be exercised until the earlier of # twelve (12) months from the date of grant and # the date of the annual meeting of stockholders next following the date of grant.

Exercise of Options. Except as otherwise provided in the Plan or in an Award agreement, an Option may be exercised for all, or from time to time any part, of the Shares for which it is then exercisable. For purposes of this Section 6, the exercise date of an Option shall be the date a notice of exercise is received by the Company, together with provision for payment of the full purchase price in accordance with this [Section 6(c)]. The purchase price for the Shares as to which an Option is exercised shall be paid to the Company, as designated by the Committee, pursuant to one or more of the following methods: # in cash or its equivalent (e.g., by check); # in Shares having a Fair Market Value equal to the aggregate Option Price for the Shares being purchased and satisfying such other requirements as may be imposed by the Committee; provided, that such Shares have been held by the Participant for no less than six months (or such other period as established from time to time by the Committee in order to avoid adverse accounting treatment applying generally accepted accounting principles); # partly in cash and partly in such Shares or # if there is a public market for the Shares at such time, through the delivery of irrevocable instructions to a broker to sell Shares obtained upon the exercise of the Option and to deliver promptly to the Company an amount out of the proceeds of such Sale equal to the aggregate Option Price for the Shares being purchased. No Participant shall have any rights to dividends or other rights of a stockholder with respect to Shares subject to an Option until the Participant has given written notice of exercise of the Option, paid in full for such Shares and, if applicable, has satisfied any other conditions imposed by the Committee pursuant to the Plan.

EXERCISE OF OPTIONS. Options granted under this Article 6 shall be exercisable at such times and be subject to such restrictions and conditions as the Committee shall in each instance approve, which need not be the same for each grant or for each Participant.

Exercise of Options. 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, and the right to exercise the Option of any executors or administrators of the Optionee’s estate or any person who has acquired such Option(s) directly from the Optionee by bequest or inheritance. 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 Service.
