Other Events IMG Technology, LLC ("IMG"), an 80% owned subsidiary of Immunomedics, Inc.("Company"), has formed a joint venture with Coulter Corporation ("Coulter") for the purpose of developing targeted cancer therapeutics. The joint venture, known as IBC Pharmaceuticals, LLC ("IBC"), was organized as a Delaware limited liability company. On March 5, 1999, the Company contributed to IBC, on behalf of IMG, certain rights to its proprietary humanized antibodies against the cancer marker carcinoembryonic antigen, which is used in its CEA-Cide(a) therapeutic, and Coulter contributed to IBC certain rights to its bispecific targeting technology called the "Affinity Enhancement System" or AES. The Company assigned its rights pursuant to the terms of a license agreement with IBC dated March 5, 1999 in exchange for the grant to IMG of a 53.28% interest in IBC ("Immunomedics License Agreement"). Coulter received a 46.72% interest in IBC in exchange for its contribution. The license granted to IBC is a worldwide, royalty free, exclusive license which is limited to the "IBC Field" with respect to the "Immunomedics Patent Property" and the "Immunomedics Biotechnology Assets," as those terms are defined in Section 1 of the Immunomedics License Agreement. Additionally on March 5, 1999, several investors contributed $3,000,000 to IBC in exchange for a 7% interest in the venture, resulting in a corresponding reduction of IMG's and Coulter's interests in IBC to 49.55% and 43.45% respectively. Coulter, IMG and the investors entered into an operating agreement (the "IBC Operating Agreement") which establishes the rights and obligations of the respective members. Under the terms of the IBC Operating Agreement, neither IMG nor Coulter may sell any portion of its interest in IBC without first providing the other with a right of first refusal with respect to such sale, provided that after a public offering of IBC securities, IMG and Coulter will be permitted to sell up to 20% of their respective interests in IBC free of such right of first refusal. IMG is a Delaware limited liability company owned 80% by the Company and 20% by Dr. David Goldenberg. Dr. Goldenberg, who is the Chairman of the Board of the Company, received his interest pursuant to the terms of his employment agreement with the Company. IMG is intended to be a single purpose entity, its sole asset being its interest in IBC.
