Eisai Co., Ltd. (Headquarters: Tokyo, President & CEO: Hauro Naito) entered into an asset purchase agreement with Robert Bosch GmbH (Bosch Group) on February 8, 2012 concerning the transfer of the entire stock and equity interest (100% of total shares issued or equity interest) of the four subsidiaries that comprise the Eisai Group's machinery business to the Bosch Group.

Under the terms of this agreement, the Eisai Group plans to transfer 100% of total shares held in Eisai Machinery Co., Ltd. (Headquarters: Tokyo, President: Kenji Hanawa), the Group's Japan pharmaceutical machinery subsidiary and the sole owner of China-based Eisai Machinery Shanghai Co., Ltd. (Headquarters: Shanghai, President: Kenji Hanawa), to Bosch Packaging Technology K.K. (Headquarters: Tokyo, President: Joachim Baczewski). The Group will also transfer its interest in its U.S. pharmaceutical machinery sales subsidiary Eisai Machinery U.S.A. Inc. (Headquarters: New Jersey, President: Michael de la Montaigne) to Robert Bosch North America Corporation (Headquarters: Michigan, President & CEO: Werner Struth) as well as its 100% equity interest in European-based Eisai Machinery GmbH (Headquarters: Koeln, Director: Masao Kageyama) to Robert Bosch GmbH (Headquarters: Stuttgart, Chairman: Franz Fehrenbach). The transfer of all shares and equity from all four subsidiaries is scheduled to take place on March 30, 2012.

1. Reasons for the Transfer of Shares

Eisai Machinery Co., Ltd. is a wholly-owned subsidiary of Eisai Co., Ltd. that was established in 1964 by Health Co., Ltd. and merged with Eisai’s machinery business (absorption type company split) in 2004. The company is engaged in the manufacture, sales and export of pharmaceutical machinery as well as the sales of packaging materials. Eisai Machinery Co., Ltd., Eisai Machinery U.S.A. Inc., Eisai Machinery GmbH and Eisai Machinery Shanghai Co., Ltd. (four companies hereinafter collectively referred to as “Eisai Machinery”) are responsible for global sales of pharmaceutical machinery and have made substantial contributions to quality inspection at pharmaceutical companies worldwide. As a member of the Eisai Group, Eisai Machinery has established an operational presence by overseeing the entire process from development through production, marketing, and after-sales service of liquid formulation inspection machines and other machinery as it seeks to enhance corporate value through the provision of high-quality and highly-sophisticated manufacturing line machinery, such as its Automatic Inspection Machine (AIM), for use in the production of pharmaceuticals.

The Eisai Group believes that given the increasingly severe conditions in the pharmaceutical machinery market, it is essential that Eisai Machinery form a strategic alliance with a company that possesses state-of -the-art production technology and know-how in order to be able to ensure the continuous delivery of new and innovative products to the global market. The Group believes that the Bosch Group’s presence in the global market as well as its pharmaceutical packaging machinery-related technology and knowledge will create great synergy that will ensure the future prosperity of Eisai Machinery, and has therefore decided to transfer the entire share and equity interest from all four subsidiaries to the Bosch Group. This agreement will enable the Eisai Group to further focus its resources on its pharmaceutical business in order to accelerate innovation and enhance corporate value.
