IMPAX Achieves Milestone in Efforts to File Delinquent Periodic Reports

July 25, 2007

HAYWARD, Calif.--(BUSINESS WIRE)--July 25, 2007--IMPAX Laboratories, Inc. (OTC:IPXL) ("IMPAX" or the "Company") reported that it has completed its discussions with the Office of the Chief Accountant ("OCA") of the Securities and Exchange Commission ("SEC") concerning the manner in which the Company will account for transactions under its Strategic Alliance Agreement with an affiliate of Teva Pharmaceutical Industries, Ltd. The Company is proceeding with the completion of the audits of its 2004, 2005 and 2006 financial statements and, based on information currently available, estimates that it will be able to bring its SEC filings current within eight to twelve weeks.

IMPAX has not filed a periodic report with the SEC since its report for the period ended September 30, 2004 because, as previously announced, it has been working to determine the appropriate accounting treatment for transactions under the Teva agreement and has sought the guidance from the OCA as to its proposed treatment.

"This is the milestone toward which we've been working for more than two years," commented Senior Vice President and Chief Financial Officer Arthur A. Koch, Jr., "as it has been the key to completion of our audits and ability to file our delinquent reports. We are grateful for the cooperation we have received from everyone involved in the process and look forward to once again providing our investors with financial statements on a current basis."
