The Company and China Huaneng Group ("Huaneng Group") own 20% and 51% equity interest, respectively, in Huaneng Finance, a non-bank financial institution in China.

The Agreement was entered into following arms' length negotiations between the Company and Huaneng Finance. Under the Agreement, the Company will from time to time place deposits with Huaneng Finance at rates which are no less favorable to the Company than the rates available from an independent third party for similar services in the PRC. In addition, the Company will also utilize the notes discounting services by Huaneng Finance by paying it a service fee on terms more favorable than the services fees charged by an independent third party for similar services in the PRC. The Agreement is valid for three years and may be renewed for further periods to be agreed or be replaced by new agreement upon the parties' mutual consent. The Company estimates that the maximum outstanding balances of deposits during the term of the Agreement will not exceed RMB6,000 million. This cap is proposed by the Company based on a number of factors, including the expanding asset scale and the increasing amount of deposits of the Company. The Company also estimates that the total amount of the notes discounting services during the term of the Agreement will not exceed RMB1,850 million per annum. Huaneng Power Int'l, Inc.
