Terms of Plan	To the extent that any award should expire, become un-exercisable or is otherwise forfeited, the shares subject to such award will again become available for issuance under the Plan. The Plan provides for the granting of stock options and restricted stock purchase rights (RSU) to our employees and consultants. Stock options granted under the Plan may be incentive stock options or nonqualified stock options. Incentive stock options ("ISO") may only be granted to our employees (including officers and directors). Nonqualified stock options ("NSO") and stock purchase rights may be granted to our employees and consultants. The Plan will expire 10 years after it was approved by our Board of Directors. Options may be granted under the Plan with an exercise price determined by our Board of Directors, or a duly appointed committee thereof, provided, however, that the exercise price of an option granted to any employee shall be not less than 100% of the fair market value at the date of grant in the case of ISO or 85% of the case of an NSO, the exercise price of an ISO or NSO granted to one of our Named Executive Officers shall not be less than 100% fair market value of the shares at the date of grant and the exercise price of an ISO granted to a 10% shareholder shall not be less than 110% of the fair market value of the shares on the date of grant. Stock options granted under the Plan typically vest over four years and have a 10 year term. All RSUs are considered to be granted at the fair value of our stock on the date of grant because they have no exercise price. RSUs typically vest over four years.
