Teva Announces Launch Of Generic Wellbutrin Xl® Tablets, 300 Mg Under Agreement With Anchen And IMPAX

Jerusalem, Israel, December 18, 2006 - Teva Pharmaceutical Industries Ltd. (NASDAQ: TEVA) announced today that it has commercially shipped Bupropion Hydrochloride Extended-Release Tablets, 300 mg, the generic version of Biovail Corporation's antidepressant Wellbutrin XL® Tablets, pursuant to an agreement with IMPAX Laboratories, Inc. (NASDAQ:IPXL) and Anchen Pharmaceuticals, Inc. Wellbutrin XL® Tablets, 300 mg, marketed by GlaxoSmithKline, had U.S. sales of approximately $972 million for the 12 months ended September 2006, according to IMS data.

Under the agreement, Anchen has taken the regulatory steps necessary to permit IMPAX to obtain final U.S. Food and Drug Administration approval of IMPAX's Bupropion Hydrochloride Extended-Release Tablets, 300 mg and for Teva to sell the product within Anchen's 180-day exclusivity. In return, Anchen will receive certain payments, both during and after the exclusivity period. Pursuant to Teva's existing strategic alliance agreement with IMPAX, Teva has U.S. marketing rights to IMPAX's version of this product. Teva will record the revenues resulting from sales of the product and remit payments to Anchen and a negotiated percentage of its gross profit to IMPAX.

Anchen and IMPAX are currently in patent litigation concerning this product. Suits were brought against them by Biovail Laboratories International SRL involving their Paragraph IV certifications to U.S. Patent No. 6,096,341. Anchen has been granted summary judgment of noninfringement with regard to its product. IMPAX has filed a motion for summary judgment of noninfringement.

Anchen was the first generic applicant to file an Abbreviated New Drug Application (ANDA) containing a paragraph IV patent challenge on the patents related to the Wellbutrin XL® tablet product and consequently was granted 180 days exclusivity, which it has now transferred to IMPAX.
