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 Restricted Share Units ("RSUs") vest 100% on the date of the grant.
(2)	Each RSU represents the right to receive without payment to the Issuer, one newly-issued, fully paid and non-assessable common share of the Issuer, subject to the terms and conditions of the Issuer's Restricted Share Unit Plan (the "RSU Plan") and the grant certificate evidencing each grant. In the discretion of the Compensation Committee, upon vesting the value of the RSU grant alternatively may be paid in cash, or partly in cash and partly in common shares.
(3)	The additional securities disclosed in this Form 4 were acquired by certain funds (the "Funds") managed by Silver Creek Capital Management LLC ("Silver Creek"). An employee of Silver Creek, Marc Roston, serves as a director of the Issuer. Mr. Roston has instructed the Issuer to pay any compensation he would have received as a director directly to the Funds. The securities were acquired through the RSU Plan which is part of the Issuer's director compensation package. By reason of the provisions of Rule 16a-1 under the Securities Exchange Act of 1934, as amended, Silver Creek may be deemed to be the beneficial owner of the securities beneficially owned by the Funds. Silver Creek hereby disclaims beneficial ownership of all such securities, except to the extent of any indirect pecuniary interest therein.

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