INFORMATION RELATED TO JIANGBIN GAS THERMAL POWER PROJECT

The Jiangbin Gas Thermal Power Project is located in the central part of the
Southern Industrial Park in Jiangbin District, Binhai New Town, Shaoxing City,
Zhejiang Province, and involves the construction of four sets of gas-steam
cycle thermal power cogeneration units. In the first phase of the project, two
sets of 452 MW generating units with a total installed capacity of 904 MW will
be constructed. In December 2011, the project was approved by the National
Development and Reform Commission of Zhejiang Province. Jiangbin Gas Thermal
Project will replace the self-owned coal-fired thermal power units located
downtown to meet consumers' demand for heating in Binhai New Town and
neighboring areas and to support the primary power supply in the Shaoxing area.

Natural gas generated by Jiangbin Gas Thermal Project will be transported via
pipeline. The company, which is responsible for the construction of the natural
gas pipelines outside the plant, has been appointed and has entered into a
supply agreement with Zhejiang Provincial Natural Gas Company.

Jiangbin Thermal Power Generation Company will become a subsidiary of the
Company upon its incorporation.

INFORMATION RELATED TO THE COMPANY

plants, the sale of electricity and thermal power, and the repair, testing and
maintenance of power equipment and power-related technical services. The
Company's main service areas are in the PRC.

INFORMATION RELATED TO SHAOXING THERMAL POWER GENERATION COMPANY

Shaoxing Thermal Power Generation Company Limited is a state-owned enterprise

equipment, and to ensure that the generating units for thermal power will be
launched for operation and transmission of electric power as scheduled. The
project is expected to commence operation by the end of 2012.
