Impax’s Registration Statement on Form 10 Becomes Effective

December 09, 2008

HAYWARD, Calif. December 9, 2008 – IMPAX Laboratories, Inc. announced its Registration Statement on Form 10, which the Company filed with the Securities and Exchange Commission (“SEC”) on October 10, 2008, became effective today. Trading in the Company’s common stock may not begin until one or more market makers’ application to quote the Company’s stock is approved by the Financial Industry Regulatory Authority (FINRA), and the Company understands such approval cannot occur until all of the SEC’s comments on the Form 10 have been resolved. The Company expects to receive further SEC comments soon and will continue to work with the SEC to address and resolve their remaining comments. The Company will issue a further announcement when trading in the Company’s common stock resumes.

Arthur A. Koch, Jr., senior vice president and chief financial officer, said, “We are pleased our registration statement has become effective, moving us one step closer to the resumption of quotations for our common stock on the Pink Sheets. While we had hoped all SEC comments would be resolved prior to effectiveness, we will require additional time to review and address their comments. We will continue to work closely with the SEC staff to clear the comments as promptly as possible. Though it is difficult for us to predict the precise timing as to when the SEC's comments will be resolved, we are working diligently in an effort to complete this process before the end of the year.”
