If designated in the Notice of Grant as an Incentive Stock Option (“ ISO ”), this Option is intended to qualify as an Incentive Stock Option under Section 422 of the Code. However, if this Option is intended to be an Incentive Stock Option, to the extent that it exceeds the $100,000 rule of Code Section 422(d) it shall be treated as a Nonstatutory Stock Option (“ NSO ”).

(a) Right to Exercise . This Option is exercisable during its term in accordance with the vesting schedule set out in the Notice of Grant and the applicable provisions of the Plan and this Option Agreement.

The Exercise Notice shall be accompanied by payment of the aggregate Exercise Price as to all Exercised

Shares, together with any applicable withholding taxes. This Option shall be deemed to be exercised upon receipt by the Company of the Exercise Notice accompanied by such aggregate Exercise Price, together with any applicable withholding taxes.

(c) Method of Payment . Payment of the aggregate Exercise Price shall be by any of the following, or a combination thereof, to the extent permitted by Applicable Laws, at the election of the Optionee:

The Exercised Shares so acquired shall be issued to the Optionee as soon as practicable after exercise of the Option. No adjustment will be made for a dividend or other right for which the record date is prior to the date of issuance, except as provided in Section 22 of the Plan.
