ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT On March 25, 2005, Impax Laboratories, Inc. (the "Company") entered into an Amendment to a Strategic Alliance Agreement, dated as of June 27, 2001, between Impax and Teva Pharmaceuticals Curacao N.V. ("Teva"). The original Strategic Alliance Agreement grants Teva marketing rights to certain of our products. The products are generally produced by Impax and marketed and sold by Teva. Profits from the sale of such products are shared between the parties as provided in the Agreement. Profits are calculated based on the definition of "Net Sales" under the Agreement. Pursuant to the Amendment, the parties agreed to amend the definition of Net Sales under the Agreement by generally providing fixed percentages to be deducted from gross sales for a number of specific deductions occurring in the ordinary course of business, rather than varying amounts previously calculated or estimated by Teva under the Agreement. The Amendment provides that deductions for certain routine adjustments are based upon good-faith estimates by Teva at the time of sale, and are subject to a year-end reconciliation. The changes to the definition of Net Sales were intended to simplify the calculations under the Agreement. In addition, Teva will provide a certificate of its Chief Financial Officer with each quarterly report that it is required to give under the Agreement, certifying to the accuracy and completeness of such quarterly report. The parties also agreed that Teva would cooperate with Impax to provide reasonable and necessary information in order to enable Impax to verify Net Sales and the "Impax Margin" (as defined in the Agreement) on a quarterly basis. Except for the changes provided in the Amendment, the Agreement remains in full force and effect. See also Item 7.01 for additional information concerning Teva and the Strategic Alliance Agreement. ITEM 3.01 NOTICE OF DELISTING OR FAILURE TO SATISFY A CONTINUED LISTING RULE OR STANDARD; TRANSFER OF LISTING On March 31, 2005, Impax announced that it was unable to file its Annual Report on Form 10-K for the fiscal year ended December 31, 2004 (the "2004 Form 10-K") by March 31, 2005. On March 16, 2005, the Company filed a Notification of Late Filing on Form 12b-25 with the Securities and Exchange Commission ("SEC") for the 2004 Form 10-K, in which it stated that the Company expected to be able to file the 2004 Form 10-K by the end of March, within the 15 day extension provided by the SEC. The Company now has determined that it requires more time to complete the year-end financial closing. See Item 7.01. A copy of the press release is attached as Exhibit 99.1 to this Form 8-K and is incorporated herein by reference. 2 On March 31, 2005, Impax sent notification to NASDAQ that Impax's 2004 Form 10-K was not filed by March 31, 2005. As a result of its failure to file the 2004 Form 10-K by March 31, 2005, Impax is no longer in compliance with conditions for the continued listing of Impax's common stock on the NASDAQ Stock Market under NASDAQ Marketplace Rule 4310(c)(14), which generally requires that all reports required to be filed with the SEC shall be filed with NASDAQ on or before the date they are required to be filed with the SEC. Impax expects that NASDAQ will append a fifth character, "E", to Impax's trading symbol until it has filed the 2004 Form 10-K. Furthermore, NASDAQ can issue a delisting letter. Impax expects to request and participate in a hearing before a NASDAQ panel regarding its compliance with the listing standards. ITEM 7.01 REGULATION FD DISCLOSURE On March 28, 2005, Impax and Teva agreed to final amounts of Net Sales and Impax Margin under the Strategic Alliance Agreement for the three months and year ended December 31, 2004. These agreed amounts are not subject to future adjustment. On March 31, 2005, Impax announced that it was not able to file its Annual Report on Form 10-K for the fiscal year ended December 31, 2004. A copy of the press release is attached as Exhibit 99.1 to this Form 8-K and is incorporated herein by reference. ITEM 9.01.
