Abdalian, Jr. Chief Financial Officer (914) 785-4763 or Morgen-Walke Associates, Inc Investor Relations: Jill Meleski Press Contact: Gregory Tiberend (212) 850-5600 NOT FOR IMMEDIATE RELEASE - ------------------------- NOVARTIS PHARMA AG EXTENDS COLLABORATION WITH EMISPHERE TECHNOLOGIES TO IDENTIFY A SECOND COMPOUND -------------------------------------------------------------------- Basel, Switzerland and Tarrytown, NY, March 2, 2000 --- Novartis Pharma AG (Zurich: NOV) and Emisphere Technologies, Inc. (NASDAQ: EMIS) today announced that Novartis will extend its collaboration with Emisphere for the oral delivery of a second Novartis compound. The two companies will collaborate to select a second drug compound from several potential drug candidates. Emisphere will receive a cash payment as a result of the extension. "Our data suggests that Emisphere's oral macromolecule delivery system has the potential to be a platform for us to create a number of oral protein products. This expansion of the collaboration will allow Novartis to evaluate additional drug candidates for development with Emisphere's technology," said Joerg Rheinhardt, Ph.D., Head of Development at Novartis Pharma. Under the terms of this agreement, the two companies will work together to identify a second compound. After Novartis has selected a second compound Novartis will have nine months to exercise a previously negotiated option to acquire an exclusive worldwide license to develop and commercialize the second compound. The license agreement provides for development and regulatory milestone payments to Emisphere, plus potential royalties on product sales and equity investments at Emisphere's option. In December 1997, Novartis and Emisphere entered into a research collaboration to explore the use of Emisphere's oral delivery technology with calcitonin. In January 2000, the two companies announced positive human results with the oral delivery of calcitonin using the Emisphere technology. In February 2000, Novartis agreed to execute a license agreement with Emisphere to develop an oral form of calcitonin. Michael M. Goldberg, M.D., Chairman and Chief Executive Officer of Emisphere Technologies commented, "We are pleased that Novartis has interest in evaluating our technology for other macromolecular compounds in addition to calcitonin. Novartis' commitment to exploring Emisphere's technology for new compounds should expand our pipeline of development programs. This extension of our agreement further confirms that our drug delivery approach has the potential to create significant added value to a broad spectrum of pharmaceutical products." Novartis is a world leader in healthcare with core businesses in pharmaceuticals, consumer health, generics, eye-care and animal health.

Headquartered in Basel, Switzerland, Novartis employs about 82,000 people and operates in over 140 countries around the world. The Group recently announced plans to spin off its Crop Protection and Seeds sectors and to merge them with the agrochemicals business of AstraZeneca in the second half of 2000. Emisphere Technologies, Inc. is a biopharmaceutical company specializing in the oral delivery of therapeutic macromolecules and other compounds that are not currently deliverable by oral means.
