Participation in a Share Purchase Program through Public Tender Offering by T-Gaia Corporation

Mitsui & Co., Ltd. ("Mitsui", head office: Tokyo, President & CEO: Masami Iijima) has decided to participate in a share purchase program through public tender offering ("the Program") implemented by T-Gaia Corporation ("T-Gaia"), starting from March 1, 2011. Mitsui's participation will cover its holding of 90,000 shares of T-Gaia common stock (17.56% of total shares issued).

1. Reasons for Participation in the Program

Mitsui established Mitsui Electronic Telecommunication Services Co., Ltd. in 1992 by spinning off Mitsui's information and communications equipment sales operations. Its corporate name was changed to Telepark Corporation in 2004. Through the merger with MS Communications Co., Ltd. in 2008, it was renamed as T-Gaia Corporation. Mitsui has since built a good relationship with T-Gaia as its major shareholder.

In consideration of Mitsui's corporate strategy to optimize its business portfolio, Mitsui has decided to participate in the Program.

3. Change in the Shareholding of Mitsui in T-Gaia by the Anticipated Share Transfer Resulting from the Program

If the Program is settled through proportional distribution, the number of shares to be purchased by T-Gaia will be allocated on a pro-rata basis among participants of the Program.

Depending on the final number of shares to be transferred, it is possible that T-Gaia will cease to be Mitsui's associated company.
