BACKGROUND

In view of the requirements for energy conservation and emissions reduction in
the PRC, and based on the spirit of the document Guo Fa [2007] No. 2 "Notice of
the State Council on Approving Several Opinions of the NDRC and the SEO on
Accelerating the Closure of Small Coal-fired Power Units", the "replacing small
units with large units" policy has been strictly implemented for newly approved
nationwide coal-fired power projects since 2007. This means the replacement of
small-capacity units by the construction of large-scale, high-efficiency and
environmental-friendly new units is the State's current major policy for the
approval of coal-fired power projects.

In order to accelerate the approval of the Company's high-capacity and
high-efficiency large-scale coal-fired power projects, the Company entered into
the Agreements with Lvsigang Power Generation Company and Datang Hunan Branch,
respectively.

kW, i.e., in the aggregate sum of RMB600 million. The compensation fee is

REASONS FOR AND BENEFITS OF ENTERING INTO THE AGREEMENTS

Pursuant to the State's policy of "replacing small units with large units", the
replacement of small-capacity units by the construction of large-scale,
high-efficiency and environmental- friendly new units is the State's current
major policy for the approval of coal-fired power projects. The Company entered
into the Agreements with Lvsigang Power Generation Company and Datang Hunan
Branch to acquire or transfer shut-down capacity indices, which will help to
accelerate the approval of high-capacity and high-efficiency large-scale
coal-fired power projects of the Company and its subsidiaries, to further
optimise the power generation structure and to enhance the core competitiveness
and profitability of the Company.

The terms of the Agreements were negotiated on arm's length basis between all
parties thereto with reference to market prices in regions where the units are
located, and have been determined on normal commercial terms. The Directors
(including independent Directors) consider that the terms of the Agreements are
fair and reasonable and in the best interests of the Company and the
Shareholders as a whole.

independent Shareholders of the Company under Chapter 14A of the Listing Rules.

Directors Mr. Liu Shunda, Mr. Hu Shengmu and Mr. Fang Qinghai who have material

the principal management staff of CDC) have abstained from voting at the Board
meeting for approving the relevant Agreements.
