October 3, 2003

HAYWARD, Calif.--(BUSINESS WIRE)--Oct. 3, 2003--IMPAX Laboratories, Inc. (Nasdaq:IPXL) announced today that it has selected Deloitte & Touche LLP as its independent auditors for the fiscal year ending December 31, 2003, replacing PricewaterhouseCoopers LLP.

The decision to change auditors was made by the Audit Committee of the Board of Directors of IMPAX and was not the result of any disagreement between the Company and PricewaterhouseCoopers on any matters of accounting principles or practices, financial statement disclosure, or auditing scope or procedure.

The reports of PricewaterhouseCoopers on the Company's financial statements for the past two fiscal years contained no adverse opinion nor a disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles.

"We are impressed with the Deloitte & Touche team's extensive experience in auditing specialty pharmaceutical companies and we look forward to beginning our relationship," said Peter R. Terreri, Director and Chairman of the IMPAX Audit Committee. "We would also like to thank PricewaterhouseCoopers for the professional services that they provided IMPAX during the past seven years as our independent auditors."
