As a non-employee director, Dr. Cravatt will receive an annual cash retainer of $75,000. In addition, in connection with his election to the Board, Dr. Cravatt will be granted, on his first date of service on the Board, a stock option to purchase shares of the Company's common stock, $0.01 par value per share ("Common Stock"), having an aggregate grant date fair value equal to $600,000 using the Company's then-current Black-Scholes valuation model, and vesting as to one-third of the shares underling the stock option on each of the first, second and third anniversaries of the grant date, with an exercise price equal to the closing price of the Common Stock on the NASDAQ Global Select Market on the grant date. Following his election, Dr. Cravatt will be eligible to receive an annual equity award, in an aggregate amount to be determined by the Board upon recommendation of the People, Culture and Compensation Committee. Currently, each of the Company's non-employee directors receives an annual equity award consisting of (i) restricted stock units having an aggregate grant date fair value of $200,000 (determined based on the closing price of the Common Stock on the NASDAQ Global Select Market on the grant date) and (ii) a stock option to purchase shares of Common stock having an aggregate grant date fair value equal to $200,000 using the Company's then-current Black-Scholes valuation model, and with an exercise price equal to the closing price of the Common Stock on the NASDAQ Global Select Market on the grant date, each vesting in full on the one-year anniversary of the grant date. The Company will also reimburse Dr. Cravatt for reasonable travel and other related expenses incurred in connection with his service on the Board.

In addition, Dr. Cravatt will enter into an indemnification agreement with the Company consistent with the form of the existing indemnification agreement entered into between the Company and its non-employee directors.
