Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) This option to purchase shares of common stock vests as follows: 6.25% of the total amount of shares subject to the option shall vest on 5/6/07. 6.25% of the total amount of the shares subject to the option shall vest each three months thereafter until all shares are vested on 2/6/11.
(2) Each Restricted Stock Unit (RSU) represents a right to receive one share of the Issuers common shares without payment of specific consideration.
(3) Grants vest upon satisfaction of both of these conditions: (1) 25% of the RSUs vest on the first anniversary of the date of grant, and an additional 25% of the RSUs vest on each anniversary thereafter; and (2) 25% of the RSUs vest if the price of a share of common stock on each anniversary of the date of grant has increased at least 15%, compounded annually, over the price on the date of grant, as calculated based on a 60-calendar-day average of NASDAQ closing prices of the Companys stock. If this condition is not met for any portion of the RSUs on the relevant anniversary date, then such RSUs may vest on any of the three subsequent anniversaries if the price on such date equals or exceeds the required price. If this condition has not been met for any portion of the RSUs by the third subsequent anniversary of the relevant anniversary date, then such portion of the RSUs shall be forfeited.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.
