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)	The options vested in three equal annual installments beginning on the date indicated.
(2)	This amended Form 4 is being filed to include the Reporting Person's exercise of an option to acquire 5,000 shares of common stock on March 16, 2007. The original Form 4 correctly reported the subsequent sales of the acquired shares, but did not report the exercise of the stock option. This amended Form 4 also revises the Reporting Person's total direct holdings following the transactions on March 16, 2007, which number does not reflect subsequent transactions on March 21 and 30, 2007 that were previously reported on Forms 4. As of the date of this amendment, the Reporting Person directly holds 29,479 shares of common stock.

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

Potential persons who are to respond to the collection of information contained in this form are not required to respond unless the form displays a currently valid OMB number.
