DEREGISTRATION OF COMMON STOCK

     On October 4, 2000, the Registrant filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-8, Registration No. 333-76954 (the “Registration Statement”), for the sale of 2,068,560 shares of the common stock (the “Common Stock”), par value $.001 per share, of the Registrant under the Registrant’s 2000 Stock Incentive Plan, 1999 Non-Employee Director Stock Incentive Plan, Non-Qualified Stock Option Plan (as amended) and Amended and Restated Performance Stock Option Plan (as amended) (collectively, the “Plans”).

     On November 19, 2004, pursuant to the terms of the Agreement and Plan of Merger (the “Merger Agreement”), dated as of June 14, 2004, by and among the Registrant, QLT Inc. and Aspen Acquisition Corp., a wholly-owned subsidiary of QLT Inc., Aspen Acquisition Corp. merged with and into the Registrant, and the Registrant became a wholly-owned subsidiary of QLT Inc. Each share of Common Stock outstanding immediately prior to the effective time of the merger was converted into the right to receive one QLT common share and US$14.61 in cash, without interest. Because the Registrant is no longer a public company, this Post-Effective Amendment No. 1 is being filed to deregister all of the unissued shares of Common Stock formerly issuable under the Plans and registered under the Registration Statement.
