Former Attorney General of Louisiana, Charles C. Foti, Jr., Esq. and the law
firm of Kahn Swick & Foti, LLC announce that KSF has commenced an
investigation into Impax Laboratories Inc. (Nasdaq: IPXL).

Shares of Impax Labs was halted in aftermarket trading following Company’s
announcement that the Food and Drug Administration issued a new Form 483 with
twelve (12) observations, three (3) of which are designated as repeat
observations from inspections that occurred prior to the Warning Letter.
According to the Company, until remedial action is complete and the FDA has
confirmed compliance with current Good Manufacturing Procedures, approval of
pending and new applications listing the Hayward facility as a manufacturing
location of finished dosage forms may be withheld.

KSF’s investigation is focusing on whether Impax Labs and/or its officers and
