BACKGROUND

The Company entered into the Ash Disposal Agreement with NCPGC on 5 August
1996. On 16 March 2004, the Company, CDC and NCPGC entered into the Variation
Agreement to the Ash Disposal Agreement, pursuant to which NCPGC transferred
all its rights and obligations under the Ash Disposal Agreement to CDC. The Ash
Disposal Agreement (as revised by the Variation Agreement to the Ash Disposal
Agreement) provided that CDC was responsible for disposing of all the ashes
generated by the power plants of the Company in accordance with the PRC's
national and local environmental protection requirements and industry policies.

The Company and CDC renewed the Supplemental Agreement to the Ash Disposal
Agreement for a term of 3 years in 2005 and 2008, respectively. Since the 2008
Supplemental Agreement to the Ash Disposal Agreement will expire on 21 August
2011 and that the ash yards owned by CDC are located in the vicinity of the
power plants owned and managed by the Company, and also with an aim to reduce
operating costs and enhance overall benefits of the Company, the Company
entered into the 2011 Supplemental Agreement to the Ash Disposal Agreement with
CDC on 22 March 2011 in order to continue to engage CDC to provide ash-disposal
services to the power plants of the Company.

THE 2011 SUPPLEMENTAL AGREEMENT TO THE ASH DISPOSAL AGREEMENT

Date

22 March 2011

Parties

(i) the Company; and

(ii) CDC.

Subject Matter

The scope of the services to be provided by CDC pursuant to the 2011
Supplemental Agreement to the Ash Disposal Agreement remains unchanged under
the Ash Disposal Agreement. CDC will continue to be responsible for disposing
of all ashes generated by the power plants which are wholly-owned, operated and
managed by the Company in accordance with PRC national and local environmental
protection requirements and industry policies.

Term

The 2011 Supplemental Agreement to the Ash Disposal Agreement is effective for
a term commencing from the date of the agreement and expiring on 31 December
2013.

Pricing

The Company and CDC will continue to agree annually on the unit ash disposal
fee, which shall reflect CDC's estimated operating costs, depreciation of its
ash yards, amortisation charges for the construction of the ash yards and a
profit margin (to be confirmed annually by the Company and CDC based on arm's
length negotiations between the Company and CDC), ranging between 5% to 10% of
CDC's costs. The ash disposal fees will continue to be determined between the
Company and CDC based on the actual volume of ashes disposed of by CDC every
month at the agreed unit ash disposal fee, and payable by the Company in cash
to CDC on an annual basis. The ash disposal fees levied by CDC under the 2011
Supplemental Agreement to the Ash Disposal Agreement from the Company are no
less favourable to the Company than terms available from other independent
third parties.

Annual Caps

The maximum annual ash disposal fees payable to CDC by the Company for each of
the three years ending 31 December 2013 under the 2011 Supplemental Agreement
to the Ash Disposal Agreement is RMB57,890,000, which have been determined with
reference to the historical transaction amounts in relation to the provision of
ash disposal services by CDC to the Company in the past three years, which
amounted to RMB57,890,000, RMB57,890,000 and RMB57,890,000, for the years ended
31 December 2008, 31 December 2009 and 31 December 2010, respectively.

During the period from 1 January 2011 to the date of the 2011 Supplemental
Agreement to the Ash Disposal Agreement, the Company has made a provision for
ash disposal charges under the 2008 Supplemental Agreement to the Ash Disposal
Agreement amounting to RMB14,470,000, which has not yet been paid by the
Company as at the date of this announcement.
