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)	Non-qualified option granted as compensation for service on the issuer's Board of Directors and for attendance at Board meetings. Non-employee directors have sometimes received compensation in the form of options to purchase shares of the issuer's common stock at below market prices ($0.25 per share), in lieu of cash payments of $4,500 quarterly ($8,750 quarterly for service of the Chairman of the Board), $1,500 per Board meeting attended in person or by videoconference and $500 per meeting attended by telephone. The number of shares for each such option grant was calculated using the closing price of the issuer's common stock for the date of a Board meeting or, with respect to the quarterly retainer payments, the closing price for the last business day of the quarter, less the option price of $0.25 per share. The options so issued were fully vested upon issuance.
