Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 5(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) Reflects a 1-for-1.9 reverse stock split, which became effective on May 7, 2004, pursuant to which the number of shares of common stock was divided by 1.9. The reporting person's original Form 3 incorrectly reported that 233,333 shares of common stock were beneficially owned by the reporting person. In addition, as a result of the error in the original Form 3, the Form 4 filed by the reporting person after the original Form 3 was filed incorrectly reported the amount of securities beneficially owned following the reporting transaction.

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.
