IMPAX Reports SEC Actions.

HAYWARD, Calif. -- IMPAX Laboratories, Inc. (OTC:IPXL) ("IMPAX" or the "Company") reported that on Friday December 29, 2006, the Securities and Exchange Commission ("SEC") issued an order instituting an administrative proceeding to determine whether, in light of the Company's failure to file reports since September 2004, the registration of its securities under Section 12 of the Securities Exchange Act of 1934 should be suspended or revoked. An Administrative Law Judge will consider the evidence in this matter and is ordered to issue an initial decision within 120 days. Also on December 29, 2006, the SEC suspended trading in IMPAX shares during the 10-business-day period from December 29, 2006 through January 16, 2007 because of the Company's failure to file reports.

The Company has not filed a periodic report since its report for the period ended September 30, 2004 because, as it announced in May 2005, it 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 continues to make significant progress in determining the appropriate accounting treatment and completing its 2004 and 2005 financial statements and is optimistic that its continued progress will enable it to avoid such suspension or revocation of the registration of its securities.

The Company understands that trading in its stock may resume on January 17, 2007 and that dealers will be permitted to publish quotations only on behalf of customers that represent customers' indications of interest and do not involve dealers' solicitation of such interest.

The Company also reported that its available cash and investments at December 31, 2006 was approximately $30.2 million. The Company continues to actively develop, manufacture and ship products and received nine FDA approvals during 2006, including the recent approval of its generic version of Wellbutrin XL 300mg, a product marketed by GlaxoSmithKline that had U.S. sales of $1.0 billion during the 12 months ended October 31, 2006 according to Wolters Kluwer Health.
