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)	Represents the exercise of an incentive stock option. The exercise was accomplished using a form of cashless, net exercise whereby Mr. LeDoux provided an attestation to the Company as to his ownership of a sufficient number of shares of common stock of the Company to pay the aggregate exercise price based on the last reported sale price for the common stock as reported by Nasdaq on June 4, 2010, which shares were deemed to be "surrendered" to the Company as payment for the exercise price. The actual number of new shares issued to Mr. LeDoux was equal to the difference between the number of shares underlying the options exercised and the shares deemed to have been surrendered.
(2)	The securities vested 34% on August 28, 2001 and an additional 33% on each of August 28, 2002 and 2003.
