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) On December 15, 2008, the number of shares of Common Stock indicated in Table I were sold by a broker as part of group sales on behalf of the Reporting Person and certain other employees of the Issuer to pay their respective withholding tax liabilities incident to the vesting of Restricted Shares. The number of shares sold was inadvertently determined on the basis of estimated tax liabilities, which exceeded the Reporting Person and such other employees' actual tax liabilities. Consequently, on December 23, 2008, the broker repurchased the numbers of shares of Common Stock indicated in Table I on behalf of the Reporting Person as part of a group purchase for such employees. The Reporting Person has disgorged to the Issuer the deemed profit from these transactions made on his behalf even though they were made without his knowledge.
(2) The Price indicated in Table I represents the weighted average sales price for price increments ranging from $0.1419 to $0.1445. The Reporting Person undertakes to provide, upon request by the Securities and Exchange Commission staff, the Issuer or a security holder of the Issuer, full information regarding the number of shares sold at each separate price for all transactions reported on this Form 4.

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.
