DETAILS OF THE EQUITY INTEREST PROPOSED TO BE ACQUIRED

Kangding Hydropower was established in September 2005 with a registered capital
of RMB18.29 million, and its 100% equity interest is held by Kangding Guoneng.
Kangding Hydropower owns and operates 2×8MW hydropower units, responsible for
providing power supply to the construction of Changheba Hydropower Station and
Huangjinping Hydropower Station of Ganzi Hydropower, a subsidiary of the
Company.

As at 30 June 2014, the total assets, the liabilities and the owner's equity of
Kangding Hydropower were RMB70.6076 million, RMB18.0038 million and RMB52.6038
million respectively. The realised net profit for the period between January
and June of 2014 was RMB5.7636 million. (Figures stated in this paragraph are
unaudited).

financial year ended 31 December 2012 were RMB27.0063 million and RMB20.2525
million, respectively. The net profit of Kangding Hydropower before and after

and RMB27.0147 million, respectively.

upon completion of the equity transfer.

REASONS FOR AND BENEFITS OF ENTERING INTO THE PROPERTY TRANSACTION AGREEMENT

As Changheba Hydropower Station and Huangjinping Hydropower Station of Ganzi
Hydropower are currently under construction, Kangding Hydropower provides part
of the electric power it generates to support the construction of both. The
acquisition is able to smooth the management relationship and guarantee the
smooth development of construction projects of Ganzi Hydropower. Besides,
Kangding Hydropower is currently equipped with hydropower units of a capacity
of 16MW installed, the acquisition will increase the Company's installed
capacity of hydropower and meanwhile expand its size of generating units in
service.

The Directors, including independent non-executive directors, are of the view
that the acquisition of the equity interest under the Property Transaction
Agreement is entered into based on normal commercial terms, and the related
transaction is fair and reasonable and is in the interest of shareholders of
the Company as a whole.

including Chen Jinhang, Hu Shengmu and Fang Qinghai are key members of the
