International Isotopes Inc. Announces It has Formed a Joint Venture with RadQual LLC and Acquired the Assets of Technology Imaging Services Inc.


IDAHO FALLS, Idaho, Dec. 15, 2010 - International Isotopes Inc. (OTC Bulletin Board: INIS) announces the Company has formed a new joint venture business on a 50-50 ownership basis with RadQual LLC, and has acquired the assets of Technology Imaging Services Inc. (TIS). TIS had been a major distributor of products and services for nuclear medicine, nuclear cardiology, and PET imaging. In 2009 Technology Imaging had gross revenues of about $6 million. The new joint venture will be called T I Services LLC.

The purchase was completed for an undisclosed sum between the joint venture and Huntington Bank, which had recently foreclosed on the assets of TIS. The assets acquired included all of TIS's accounts receivable, customer data base, office equipment, and inventory. RadQual and the Company plan to rehire employees of TIS and to continue business in the same manner as Technology Imaging. TIS had been a profitable business but became overwhelmed with debt from past management practices.

Steve T. Laflin, President and CEO of International Isotopes Inc. said, "We are working to make this transition a seamless process to our customers. TIS had been nationally recognized as a major distributor for a wide range of nuclear medicine and nuclear cardiology products and had an excellent reputation for offering complete product lines, customer service, and competitive pricing. We plan to work closely with RadQual in establishment of the new TI Services joint venture and to aggressively expand sales in this new organization. The formation of the joint venture with RadQual also represents a further expansion of the strong business relationship that has existed between RadQual and International Isotopes since we began providing contract manufacturing services for RadQual in 2001. We believe this joint venture will more closely integrate manufacturing with distribution and sales of our products and anticipate it will improve our margins and facilitate the expansion of sales."

Peter Ouimette of RadQual states, "We are excited to have this opportunity to build a new sales focused organization from the foundation of the former Technology Imaging Services. It's an additional bonus to acquire a core group of people with a high level of market knowledge and dedication to customer service. This as an extraordinary doorway to growth of our existing and future product lines within both the domestic and international marketplace and we welcome the challenge."
