Mitsui & Co., Ltd. ("Mitsui", Headquarter: Chiyoda-ku Tokyo, President & CEO: Masami Iijima) announced today that it has entered into a share transfer agreement with Industrie De Nora S.p.A., Italy ("IDN", Headquarter: Milan, Italy, CEO: Gianfranco Mora) to transfer to IDN of 51% shares of Mitsui in Chlorine Engineers Corp. Ltd. ("CEC") engaging in engineering and manufacturing of electrolysis devices, which Mitsui own a 100% issued share through a fully owned investment company. The transaction is scheduled to be completed in November 2010.

CEC was established as an electrolysis plant manufacture by Mitsui in 1973 given the market situation that a notice to switch from mercury electrolysis to other method was issued by the Ministry of International Trade and Industry in 1973 due to Minamata mercury pollution. Since then, we have developed various technologies such as for the diaphragm, mono-polar and bi-polar ion exchange membrane processes. CEC has been expanding its business as a leading company of its field of business enjoying more than 30% of global market share in ion exchange membrane method of sodium chloride electrolysis plant. In light of the need to enhance the global presence of CEC worldwide, and serve its Customer with better maintenance services, Mitsui and CEC have concluded that establishment of an equity partnership with IDN who owns a highly developed portfolio of electrolysis technologies, vast experience and global network in this area of business, is the most beneficial option for ensuring CEC's further sustainable growth in the market. CEC, with the support of IDN shall also be able to speed up the introduction of the several newly developed environmental technologies. IDN shares this strategy and agreed to their acquisition of a majority of the shares in CEC today.

We will continue to aim at CEC's further growth in global market having alliance with IDN.
