IMPAX Reports SEC Actions

May 1, 2007

HAYWARD, Calif.--(BUSINESS WIRE)--May 1, 2007--IMPAX Laboratories, Inc. (OTC: IPXL) ("IMPAX" or "the Company") reported that on April 30, 2007, an Administrative Law Judge ("ALJ") of the Securities and Exchange Commission ("Commission") issued an initial decision that, if upheld by the Commission itself, would result in the revocation of the registration of the Company's common stock under section 12 of the Securities Exchange Act of 1934. The Company will file a timely appeal to the Commission and hopes to persuade the Commission, based upon the evidence developed in a two-day hearing in February before the ALJ, that revocation or suspension of such registration is neither necessary nor appropriate for the protection of investors. The ALJ's decision will not be effective during the pendency of the appeal.

The ALJ's initial decision is based upon the Company's failure to file periodic reports since its quarterly report for the period ended September 30, 2004. As previously announced, the reason for this reporting delinquency is that the Company has been working to determine the appropriate accounting treatment for transactions under its Strategic Alliance Agreement with an affiliate of Teva Pharmaceutical Industries, Ltd. The Company has now developed an accounting treatment that it deems appropriate and is awaiting the concurrence of the Commission's Office of the Chief Accountant ("OCA") in its proposed treatment. Although it cannot predict when the OCA will reach a conclusion, the Company currently estimates that it will be in a position to file all of its delinquent reports within two to three months following a favorable determination by the OCA.

The Company also reported that its available cash and investments at March 31, 2007 was approximately $46.6 million, compared with $29.1 million at December 31, 2006. The Company continues to actively develop, manufacture and ship pharmaceutical products and received nine FDA approvals during 2006.
