Medarex to invest $2 million in Seattle Genetics

Bothell, WA and Princeton, NJ: February 7, 2001— Seattle Genetics, Inc. and Medarex, Inc. (Nasdaq: MEDX) today announced the formation of a strategic alliance through which the two companies expect to utilize Medarex's UltiMAb™ Human Antibody Development SystemSM to jointly develop and commercialize monoclonal antibody-based therapeutic products against specific cancer targets.

Under this alliance, Seattle Genetics will provide the collaboration with novel cancer targets. Medarex plans to generate fully human antibodies to these targets using its UltiMAb Human Antibody Development System. The two companies will share preclinical and clinical development costs and have the right to jointly commercialize any resulting products. In addition, Medarex will purchase $2 million of common stock directly from Seattle Genetics in a private placement concurrent with Seattle Genetics' proposed initial public offering.

“We are very pleased to add Seattle Genetics as a partner,” said Donald L. Drakeman, President and Chief Executive Officer of Medarex. “We are impressed by Seattle Genetics' proven ability to discover and move products into the clinic. By combining their efforts with Medarex's UltiMab technology, we believe this partnership positions both companies to rapidly develop and commercialize fully human antibody therapeutics.”

Seattle Genetics discovers and develops monoclonal antibody, or mAb, -based therapeutics to treat cancer and related diseases. Seattle Genetics utilizes its mAb-based technologies to increase the potency and efficacy of antibodies with specificity for cancer. Seattle Genetics has four mAb-based technologies: engineered mAbs, mAb-drug conjugates, single-chain immunotoxins, and antibody-directed enzyme prodrug therapy. Using these technologies and its expertise in cancer, Seattle Genetics has built a diverse portfolio of drug candidates targeted to many types of human cancers, including two currently being tested in clinical trials.
