To Whom It May Concern

Mitsui & Co., Ltd.

Acquisition of Water Treatment Plant Operation Assets in China by

Galaxy NewSpring Pte. Ltd.

Galaxy NewSpring Pte. Ltd. (“Galaxy”, head office: Singapore), a joint venture company that is equally held by Mitsui & Co., Ltd. (“Mitsui”, head office: Tokyo, CEO: Masami Iijima), and Hyflux Ltd. (“Hyflux”, head office: Singapore, CEO: Olivia Lum), has closed the Exit Offer of Hyflux Water Trust (“HWT”) on November 12, 2010 (“Final Closing Date”).

On August 2, 2010, Galaxy publicly announced an Exit Offer of HWT, a public business trust listed on the Singapore Exchange Securities Trading Limited, which wholly owns 18 water treatment plant operations assets (“18 Operation Assets”) in China. As of the Final Closing Date, Galaxy has received valid acceptance of approximately 62.04% of total Offer Units, resulting in an ownership of approximately 93.88%(*1) of issued Units of HWT, including approximately 31.79% of issued Units acquired by Hyflux and its wholly owned subsidiary companies. Galaxy plans to acquire the remaining 6.12% of the issued Units by the end of December 2010, and wind-up HWT upon completing the acquisition of the 18 Operation Assets.

Galaxy will operate the 18 Operation Assets along with the 4 water treatment plant operation assets in China (“4 Operation Assets”), which Galaxy has acquired from Hyflux on September 30, 2010 (collectively “22 Operation Assets”). The total purchase price for the 22 Operation Assets is approximately 20 billion JPY, and the total designed capacity is 745,000m3/day (825,000m3/day, after expansion).

Mitsui, together with Galaxy, will continue to capture the fast growing water infrastructure demand in China, and expand its water business with new customers, such as local governments and industrial parks.

As a proactive integrated water solution provider, Mitsui will continue to help solve the various water related problems the world is facing today.
