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)	These are performance-based restricted stock units ("PSU") with terms as follows. The term of each PSU award runs from the grant date through the third anniversary of the grant date. Any unvested PSUs remaining after the third anniversary will be cancelled. The performance period for the award is the same three-year period. PSUs will vest on or after the first anniversary of the grant date only if the stock price meets the performance hurdle. The performance hurdle is met if the average closing price of the Company's common stock over any 60 consecutive trading days during the performance period equals two times the base price. The base price was calculated as the average closing price over the ten trading days ending on the trading day prior to the grant date and is $2.14 for this award.
Remarks: This award was inadvertently omitted from the original 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.
