Notes:

1. As audited by RSM China Certified Public Accountants Co., Ltd. and RSM
   Nelson Wheeler, net profit attributable to the equity holders of the Company
   for the fiscal year ended 31 December 2010 under PRC Accounting Standards for
   Business Enterprises and International Financial Reporting Standards amounted
   to approximately RMB2,473,680,000 and RMB2,569,730,000, respectively. The
   Company withdrew 10% of the net profit of the parent company under PRC
   Accounting Standards for Business Enterprises as statutory surplus reserve
   amounting to approximately RMB207,600,000 and withdrew discretionary surplus
   reserve amounting to RMB1,407,800,000.

   The Company's profit distribution proposal for the year 2010 is as follows:

   Based on the Company's total share capital (as at 22 March 2011, the Company's
   total share capital was 12,310,037,578 shares), the Company proposes to
   distribute a dividend of RMB0.07 per share (tax included) to all shareholders
   and the total amount of the proposed cash dividends to be distributed amounting
   to approximately RMB861,700,000.

2. The Company will, based on the actual needs of its subsidiary, Inner
   Mongolia Datang International Tuoketuo Power Generation Company Limited
   ("TPGC"), release an entrusted loan of not more than RMB3 billion to TPGC
   through China Datang Finance Company for the repayment of due loans and
   replenishment of working capital of TPGC. The provision of entrusted loan
   constitutes connected transaction of the Company and any shareholder that holds
   material interest in the transaction and its associates should abstain from
   voting on this resolution in the AGM.

   Please refer to the announcement of the Company dated 13 April 2011 and the
   circular to be issued by the Company in relation to the provision of the

   year 2011. The appointment term is one year with the audit fee amounting to
   RMB13,780,000 (excluding the audit fee of internal control).

   financing by Hebei Datang International Wind Power Development Co., Ltd.
   ("HWPC") in an amount of not exceeding RMB720 million for project construction
   and replacement of due loans. Given that the asset-liability ratio of HWPC is
   over 70%, this resolution on provision of guarantee is required to be submitted
   to the general meeting for shareholders' approval.

   Please refer to the announcement of the Company dated 13 April 2011 for details
