IMPAX Settles Solvay Litigation

June 29, 2006

HAYWARD, Calif.--(BUSINESS WIRE)--June 29, 2006--IMPAX Laboratories, Inc. (OTC:IPXL) announced today it has settled a suit brought against it in 2003 by Solvay Pharmaceuticals, Inc. alleging that IMPAX engaged in false advertising practices dating back to 1998 in connection with the marketing of two of the Company's ten Lipram pancreatic enzyme supplements as well as two discontinued pancreatic enzyme supplements. Under the settlement, IMPAX will pay $23 million to the plaintiffs, of which $12 million will be paid immediately from the Company's cash reserves, which total approximately $42 million currently. The balance will be paid over the next six years. Sales and gross profits from these two Lipram products were not material to IMPAX's results.

Barry R. Edwards, IMPAX's CEO, commented, "Although we continue to believe that our advertising of these products was neither false nor misleading and that Solvay's suit was without merit, in view of the potential expense, diversion of management and risks that would have been involved in an upcoming jury trial in this case, we entered into what we believe to be a prudent settlement that will result in dismissal of the suit. It is in the best interest of shareholders to put this suit behind us."
