IMPAX Provides Updates on Progress to File 10-K and Related Matters

May 04, 2005

HAYWARD, Calif., May 04, 2005 (BUSINESS WIRE) -- IMPAX Laboratories, Inc. (NASDAQ:IPXLE) today reported steps taken to complete its financial closing and file its Annual Report on Form 10-K for the year ended December 31, 2004. The Company, in consultation with its auditor, decided to approach the Office of the Chief Accountant of the Securities and Exchange Commission ("SEC") to discuss the Company's accounting for its transactions under its Strategic Alliance Agreement with a subsidiary of Teva Pharmaceutical Industries Ltd. ("Teva") prior to filing its 2004 Annual Report on Form 10-K. The Company is presently preparing its submission.

As previously announced, the Company and Teva have agreed to the net sales and margin allocable to IMPAX for 2004 and have also agreed not to make any further adjustments to such agreed amounts. The Company refers to this agreement as the 2004 Close-Out Letter. Additionally, the Company and Teva have entered into an amendment to the Strategic Alliance Agreement whereby, effective January 1, 2005, certain sales deductions that were previously required to be estimated have been replaced by fixed percentages thereby simplifying the accounting under the agreement. Both the 2004 Close-Out Letter and the amendment were completed in March 2005.

Until the Company completes and files its 2004 Annual Report on Form 10-K, it will not be able to file its Quarterly Report on Form 10-Q for the quarter ended March 31, 2005.

In related matters, also previously reported, on April 5, 2005, IMPAX received a Nasdaq Staff determination letter indicating that IMPAX failed to comply with the requirement for continued listing set forth in Nasdaq Marketplace Rule 4310(c)(14) because IMPAX failed to file its 2004 Annual Report on Form 10-K with Nasdaq and, therefore, IMPAX's common stock is subject to delisting from The Nasdaq Stock Market. A hearing has been scheduled before a Nasdaq Listing Qualifications Panel on May 19, 2005 to review the Staff's determination, although there can be no assurance that the Panel will grant IMPAX's request for continued listing pending its filing of its Annual Report. In the event that IMPAX's common stock is delisted from Nasdaq and is not otherwise approved for trading on any United States national securities exchange, it will constitute a "designated event" under the Indenture governing the Company's $95 million principal amount of 1.250% Convertible Senior Subordinated Debentures due 2024 (the "Debentures"), giving each Debenture holder the option to require the Company to redeem the holder's Debentures at 100% of their principal amount, together with accrued and unpaid interest.

In addition, IMPAX received a notice, dated April 22, 2005, from a holder of more than 25% aggregate principal amount of the Debentures stating that the Company failed to file its Annual Report on Form 10-K for the year ended December 31, 2004 with the SEC as required by the governing Indenture and requiring that the Company remedy such default forthwith. Under the Indenture, if the Company fails to file the Annual Report within 60 days after the date of the notice, it will constitute an "event of default" under the Indenture and thereafter either the Trustee or the holders of 25% in aggregate principal amount of the Debentures then outstanding, by notice to the Company, may declare the principal of and premium, if any, on all the Debentures then outstanding and the interest accrued thereon to be due and payable immediately.
