Parties

(i) The Company; and

(ii) China Water Resources and Power.

Subject Matter

Pursuant to the Framework Agreement for Centralised Materials Purchase, the

of production materials required for technological renovation projects,
including equipment, production spare parts and large consumable materials,
through China Water Resources and Power from other third parties suppliers.
Pursuant to the agreement under the Framework Agreement for Centralised
Materials Purchase, the Company expects that the price of such production
materials to be purchased through China Water Resources and Power shall not be
higher than the average market price of such production materials.

The Company, its subsidiaries and China Water Resources and Power will enter
into individual purchase orders setting out specific terms including the
details of the production materials to be ordered, the price, the payment terms
and schedules, but such terms shall be consistent with the principles and the
terms of the Framework Agreement for Centralised Materials Purchase.

Term

The Framework Agreement for Centralised Materials Purchase is for a term of
three years commencing from 1 January 2011 and ending on 31 December 2013.

partial payment in advance and management of suppliers. As such, China Water
Resources and Power will collect a management service fee (the relevant fee is
equivalent to 3% to 5% of the purchase amount on the purchase order). Such
management service fee is determined after arm's length negotiation between the
