  Impax Laboratories Inc.

Business Wire

SAN DIEGO -- March 5, 2013

Shareholder rights law firm Johnson & Weaver, LLP has commenced an
investigation into whether Impax Laboratories (Nasdaq:IPXL) and/or its
directors and officers violated state or federal securities laws in relation
to recent Food and Drug Administration (FDA) warnings.

Trading of Impax Laboratories shares was halted in aftermarket hours following
the Company’s announcement that the FDA issued a new Form 483 with twelve
observations, three of which are designated as repeat observations from past
inspections. New and pending applications that relate to the Hayward,
California manufacturing facility may be withheld by the FDA until the Form
483 problems are solved. Impax stock was down over 25% in early trading on
March 5, 2013, the day following the Company’s announcement which was made
after trading hours.

Johnson & Weaver's investigation is ongoing and addresses the potential
violations related to the actions of Impax, its directors and officers. Jim
Baker, Lead Analyst for Johnson & Weaver, stated that, "I would think that
Impax would have complied with the FDA Form 483 warnings by this time,
especially the issues from the March 2012 inspection.”
