LICENSE AGREEMENT THIS AGREEMENT (the "Agreement"), is made this 21st day of July 1993, by and between HemoCleanse, Inc., an Indiana corporation ("HCI"), having an address of 2701B Kent Avenue, West Lafayette, Indiana 47906, and IDT, Inc., a Pennsylvania corporation ("IDT"), having an address as The Bourse, Building 2500, Second Floor, 2275 Swallow Hill Road, Pittsburgh, Pennsylvania 15220. WITNESSETH: WHEREAS, HCI exclusively owns certain technology, patents, processes, methods, designs, technical know-how, and associated rights and tangible property required to manufacture, market and sell an extracorporeal medical device, known as the BioLogic-DT ("DT"), that utilizes sorbent chemicals, cation and anion exchangers, and other physiological substances in a closed-loop dialysate suspension to selectively remove from the blood and transfer to the blood across a membrane toxins and chemicals, thus performing both detoxification and physiological chemical balancing of the blood simultaneously (the "Technology"); and WHEREAS, HCI possesses the expertise and know-how to convert the DT into an extracorporeal hyperthermia device, known as the BioLogic-HT ("HT"), by modifying the dialysate suspension heating system to permit greater heat transfer to the blood, changing the method and rate of blood pumping and altering the chemical composition of the dialysate suspension to maintain physiological chemical balancing during hyperthermia while removing toxins caused by hypertherrnia (the "Modified Technology"); and WHEREAS, IDT is engaged in research regarding the treatment of disease or other medical condition through the use of hyperthermia, whether or not in conjunction with radiation, chemotherapy, or other methods, including, without limitation, the treatment of Kaposi's sarcoma and Acquired Immune Deficiency Syndrome ("Relevant Field of Use") and such procedure requires the Modified Technology; and WHEREAS, the parties believe that the Modified Technology can be utilized and optimized as a unique treatment system for an effective extracorporeal hyperthermia treatment procedure; and WHEREAS, IDT desires to secure from HCI, and HCI is willing to provide IDT with, an exclusive license to commercialize the Modified Technology subject to certain terms and conditions set forth in this Agreement. NOW, THEREFORE, for and in consideration of the recitals and covenants and undertakings of the parties contained herein, the parties agree as follows: ARTICLE I TERM 1.1 This Agreement shall begin on the date first written above and shall continue until terminated by agreement of the parties or as otherwise provided herein.
