In July 2009, Mitsubishi Tanabe Pharma Corporation (Head Office: Osaka; President & CEO: Michihiro

Pharma America, Inc., and , at the same time, reorganized Group Companies in the United States. As

Before the reorganization, the Company’s U.S. subsidiaries included: Tanabe Research Laboratories
U.S.A., Inc. (Head Office: California), pharmaceutical research, Tanabe U.S.A., Inc. (Head Office:
California), sales and marketing of chemicals, and their holding company, Tanabe Holding America, Inc.
(Head Office: New Jersey). In addition, the Company had Mitsubishi Pharma America, Inc. (Head

In conjunction with the establishment of MT Pharma America in July 2009, the Company placed four
Group Companies under the umbrella of the holding company: Tanabe Research Laboratories,
