 and set forth in the Award Agreement. An Option may not be exercised for a fraction of a Share.

An Option will be deemed exercised when the Company receives: (a) notice of exercise (in such form and in accordance with such procedures as the Administrator may specify from time to time) from the person entitled to exercise the Option; and (b) full payment of the exercise price for the Shares with respect to which the Option is exercised (together with applicable tax withholdings). Shares issued upon exercise of an Option will be issued in the name of the Participant or, if requested by the Participant, in the name of the Participant and his or her spouse. Until the Shares are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a stockholder will exist with respect to the Shares subject to an Option, notwithstanding the exercise of the Option. The Company will issue (or cause to be issued) such Shares promptly after the Option is exercised. No adjustment will be made for a dividend or other right for which the record date is prior to the date the Shares are issued, except as provided in Section 15.

Exercising an Option in any manner will decrease the number of Shares thereafter available, both for purposes of this Plan (except as provided otherwise under Section 3.3) and for sale under the Option, by the number of Shares as to which the Option is exercised.
