                       DEREGISTRATION OF UNSOLD SECURITIES

      This Post-Effective Amendment No. 1 relates to the Registration Statement
on Form S-3 (File No. 333-31336) (the "Registration Statement") of Kestrel
Energy, Inc. (the "Company") pertaining to 715,050 shares of the Company's
common stock, no par value ("Common Stock") and 715,050 warrants to purchase
shares of Common Stock ("Warrants"), which was filed with the Securities and
Exchange Commission and became effective on March 10, 2000. The Registration
Statement registered 2,768,271 shares of Common Stock and 728,250 Warrants. The
shares offered in the prospectus included 728,250 shares of Common Stock for
exercise of the Warrants. The Warrants expired on March 10, 2003. Prior to that
date 13,200 Warrants were exercised to purchase 13,200 shares of Common Stock.

      As a result of the expiration of the Warrants, the offering pursuant
to the Registration Statement for 715,050 shares of Common Stock and 715,050
Warrants has been terminated. In accordance with the undertaking made by the
Company in the Registration Statement to remove from registration, by means
of a post-effective amendment, any of the securities which remain unsold at
the termination of the Warrant offering, the Company hereby removes from
registration 715,050 shares of Common Stock and 715,050 Warrants of the Company
registered but unsold under the Registration Statement. The remaining 2,040,021
shares of Common Stock will remain registered under the Registration Statement.
