Teva Signs Agreement With Andrx and Impax for Generic Formulations of Wellbutrin® Sr and Zyban®

Jerusalem, Israel, July 31, 2003 - Teva Pharmaceutical Industries Ltd. (NASDAQ: TEVA) announced today that one of its subsidiaries has entered into an exclusivity transfer agreement with Andrx Corporation (NASDAQ:ADRX) and IMPAX Laboratories, Inc. (NASDAQ NM:IPXL) pertaining to pending Abbreviated New Drug Applications (ANDAs) for bioequivalent versions of Wellbutrin® SR and Zyban® (Bupropion Hydrochloride) 100 mg and 150 mg Extended Release Tablets filed by Andrx, as well as by IMPAX. Pursuant to Teva's existing strategic alliance agreement with IMPAX, Teva has U.S. marketing rights to IMPAX's versions of these products. Wellbutrin® SR and Zyban®(GlaxoSmithKline products) had U.S. sales of over $1.6 billion for the twelve-month period ended March 31, 2003 according to IMS.

The parties believe that the Andrx ANDAs for the products are entitled, under the Hatch-Waxman Act, to an 180-day period of marketing exclusivity. Under the exclusivity transfer agreement, Andrx will continue to seek approval of its ANDAs. The agreement provides, among other things, that if Andrx is unable to launch its own products within a defined period of time, and IMPAX is able to market its products, Andrx will enable IMPAX to launch its own products. IMPAX would then launch its products through Teva, with the parties sharing certain payments with Andrx relating to the sale of the products for a 180-day period. Should Andrx launch its own products prior to IMPAX launching its products, Andrx will share with Teva and IMPAX certain payments for a 180-day period.

Mr. Israel Makov, President and CEO of Teva, said: "We are pleased to enter into this agreement with Andrx and IMPAX. We believe that this agreement will facilitate the introduction of these important treatments at lower prices at the earliest possible time."

Andrx and IMPAX have both obtained favorable summary judgment decisions that their formulations of the products do not infringe GlaxoSmithKline's patents. GlaxoSmithKline, however, has appealed both decisions.

The transactions contemplated by the exclusivity transfer agreement are subject to obtaining all necessary government approvals.
