                        EXPLANATORY NOTE
     Pursuant to this Registration Statement on Form S-3 (File
No. 333-17401) (the "Registration Statement"), the Registrant
originally registered 5,474,000 shares of the Registrant's Common
Stock issuable upon exercise of the Registrant's Class A
Warrants.  This Registration Statement was originally filed on
Form S-2, but was subsequently converted into Form S-3 by Post-
Effective Amendment No. 1 to this Registration Statement.  On
February 12, 2002, all of the Registrant's Class A Warrants
expired pursuant to the terms of the Warrant Agreement governing
the Class A Warrants.  No Class A Warrant was exercised for
Common Stock prior to the expiration date of the Class A
Warrants.  The Registrant is filing this Post-Effective Amendment
No. 2 to this Registration Statement to deregister and remove
from registration those shares of Common Stock previously
registered under this Registration Statement.  This Registration
Statement is hereby amended, as appropriate, to reflect the
deregistration of such shares of Common Stock.

                           SIGNATURES
     Pursuant to the requirements of the Securities Act of 1933,
