For Immediate Release

          UNIGENE ENTERS INTO U.S. LICENSE AGREEMENT WITH UPSHER-SMITH
           LABORATORIES FOR NASAL CALCITONIN PRODUCT FOR OSTEOPOROSIS

Fairfield, NJ- December 2, 2002 - Unigene Laboratories, Inc. (OTCBB:UGNE) and
Upsher-Smith Laboratories, Inc. today announced the signing of a $10 million
exclusive U.S. licensing agreement to market Unigene's patented nasal
formulation of calcitonin for the treatment of osteoporosis.

Under the terms of the agreement, Unigene has received an up-front payment of $3
million from Upsher-Smith and will be eligible to receive milestone payments and
royalty payments on product sales. Unigene will be responsible for manufacturing
the product at its Boonton, New Jersey facility and will sell finished
calcitonin product to Upsher-Smith. Upsher-Smith will package the product and
will distribute it nationwide.

This is Unigene's second license agreement in the field of osteoporosis. In
April 2002, Unigene announced a $150 million license agreement with
GlaxoSmithKline for the development of an oral parathyroid hormone (PTH)
product.

"Unigene has developed an important calcitonin product for the treatment of
osteoporosis, which affects millions of Americans," said Ian Troup, President
and COO of Upsher-Smith Laboratories. "We look forward to bringing our expertise
in the marketing and distribution of high-quality pharmaceuticals to our
partnership with Unigene - and we look forward to bringing Unigene's calcitonin
therapy to physicians and patients."

"We are very pleased to be working with Upsher-Smith, an experienced
pharmaceutical company with great capabilities in marketing branded generics,"
commented Dr. Warren P. Levy, President and CEO of Unigene. "We believe that the
enthusiasm and commercialization strategies of Upsher-Smith for this product
will provide an outstanding opportunity for marketing this product. Furthermore,
the agreement provides another important validation for our patented
manufacturing and delivery technologies and their broad applicability to
therapeutic peptides."
