REASONS FOR AND BENEFITS OF ENTERING INTO THE KEQI INVESTMENT AGREEMENT AND THE FUXIN INVESTMENT AGREEMENT The Company has devised the objective of diversifying its business structure, and the investments in and constructions of Keqi Coal-based Gas Project and Fuxin Coal-based Gas Project by Energy and Chemical Company will allow the Company to develop on the aspect of clean energy production. The Keqi Coal-based Gas Project is located in an area with abundant coal resources which provides a reliable source of raw materials and fuels to the Keqi Coal-based Gas Project, and with abundant water resources and convenient transportation facilities which will help to lower the operation costs of the Keqi Coal-based Gas Project. Moreover, the Keqi Coal-based Gas Project aims to supply gas largely to Beijing and to cities along the gas transmission pipeline upon its completion. As a political, cultural and financial centre of the PRC, Beijing has an enormous demand for clean energy natural gas, given its higher requirement for the quality of the air environment. The Company believes the Keqi Coal-based Gas Project, upon its completion, will benefit from the growing demand for clean energy in Beijing and the cities along the gas transmission pipeline, which in turn will enhance the Company's profitability as a whole. The major supply targets of the Fuxin Coal-based Gas Project following its completion are Shenyang and the cities surrounding it such as Tieling, Fushun, Benxi and Fuxin. Liaoning Province has experienced fast economic growth and is a leader in economic development among the three provinces in northeast China and has a great demand for clean energy source such as natural gas. Besides, the above cities are relatively concentrated, which facilitates the transmission of natural gas products from this project via long-distance pipelines. With the acceleration of urbanisation, the reform in coal-fired boilers and the development of gas buses and industries using natural gas as raw material, the supply gap of natural gas in the above cities will grow bigger and bigger. The Company believes that following the completion of the Fuxin Coal-based Natural Gas Project, it will benefit from the growing demand for clean energy of Shenyang and the cities surrounding it which have experienced rapid economic development, thereby increasing the overall profitability of the Company. In view of the above, the Directors believe that the terms of the Keqi Investment Agreement and the Fuxin Investment Agreement fair and reasonable and the entering into the Keqi Investment Agreement and the Fuxin Investment Agreement is in the interest of the Company and the Shareholders as a whole and enhance the Company's overall profitability.

DISCUSSION OF MAJOR TERMS As mentioned above, the parties to the Keqi Investment Agreement have agreed to recognise the preliminary work in respect of the Keqi Coal-based Gas Project before the Keqi Investment Agreement was entered into, including (but not limited to) all expenses incurred, agreements and contracts entered into, documents submitted for record and corresponding undertakings made, so as to ensure the continuity of the preliminary work of the project. In addition, the parties to the Fuxin Investment Agreement agreed to acknowledge various recognize the preliminary work on the Fuxin Coal-based Gas Project, which have been developed by the Company, including (but not limited to) all expenses incurred, agreements and contracts entered into, documents submitted for record and corresponding undertakings made, so as to ensure the continuity of the preliminary work of the project. As the projects are in line with the business diversification strategy of the Company and that the Company holds controlling stake in the joint ventures for undertaking the projects, it is reasonable for the Company to make prior investment in the initial stage of development of the projects. Given that there are arrangements of recovering the incurred expenses by the Company and any other joint venture partners described above, we consider that it is fair and reasonable for the Company to make payments for the projects in advance. As (i) each of the Company, Beijing Gas Group, CDC and Tianjin Jinneng proportionally share their respective cash contribution to the registered capital of Keqi Coal-based Gas Company based on their respective interests in the Keqi Coal-based Gas Project; and (ii) the Company and CDC proportionally share their respective cash contribution to the registered capital of Fuxin Coal-based Gas Company based on their respective interests in the Fuxin Coal-based Gas Project, we are of the view that it is reasonable for the Company to contribute 51% and 90% of the registered capital of Keqi Coal-based Gas Company and Fuxin Coal-based Gas Company respectively. We consider that the amount of the initial capital of each of the Keqi Coal-based Gas Company and the Fuxin Coal-based Gas Company of RMB100,000,000 is reasonable considering the amount of the ultimate registered capital, the total investment amount and the nature and size of the Keqi Coal-based Gas Project and the Fuxin Coal-based Gas Project. Furthermore, we understand that the shareholders of Keqi Coal-based Gas Company and Fuxin Coal-based Gas Company shall contribute the remaining capital amount based on the construction progress of the Keqi Coal-based Gas Project and the Fuxin Coal-based Gas Project respectively. We consider that such arrangement is reasonable given the nature and size of the Keqi Coal-based Gas Project and the Fuxin Coal-based Gas Project. We understand that the total investments other than the registered capital of the Keqi Coal-based Gas Project and the Fuxin Coal-based Gas Project, i.e. 70% of the total investments, would be financed by Keqi Coal-based Gas Company and Fuxin Coal-based Gas Company respectively through financing. Since the projects require a substantial amount of investment, it might not be financially efficient to finance the projects by registered capital entirely. Therefore, we concur with the Directors' view that the remaining funds for the Keqi Coal-based Gas Project and the Fuxin Coal-based Gas Project to be financed by project loans is fair and reasonable and in the interests of the Company and the Shareholders as a whole. Since the projects require a substantial amount of investment, it would be beneficial to the Company if the joint ventures can have a long term of operation. In our view, the term of operation of Keqi Coal-based Gas Company and Fuxin Coal-based Gas Company of 50 years from the date of issuance of the relevant business licence is a reasonable one given the nature and size of the Keqi Coal-based Gas Project and the Fuxin Coal-based Gas Project. Having considered the above, we consider that the terms of the Keqi Investment Agreement and the Fuxin Investment Agreement are fair and reasonable as far as the interests of the Shareholders are concerned. 4. REASONS FOR AND BENEFITS OF ENTERING INTO THE KEQI INVESTMENT AGREEMENT AND THE FUXIN INVESTMENT AGREEMENT As mentioned in the Letter from the Board, the Company intends to diversify its business. The investments in the Keqi Coal-based Gas Project and the Fuxin Coal-based Gas Project will enable the Company to expand its electricity power generation business to other businesses in the energy sector. The Keqi Coal-based Gas Project is located in an area with abundant coal resources which provides a reliable source of raw materials and fuels to the Keqi Coal-based Gas Project, and with abundant water resources and convenient transportation facilities which will help to lower the operation costs of the Keqi Coal-based Gas Project. Moreover, the Keqi Coal-based Gas Project aims to supply gas largely to Beijing and to cities along the gas transmission pipeline upon its completion. As a political, cultural and financial centre of the PRC, Beijing has an enormous demand for natural gas, a clean energy, given its higher requirement for the quality of the air environment. The Company believes the Keqi Coal-based Gas Project, upon its completion, will benefit from the growing demand for clean energy in Beijing and the cities along the gas transmission pipeline, which in turn will enhance the Company's profitability as a whole. The major supply targets of the Fuxin Coal-based Gas Project following its completion are Shenyang and the cities surrounding it such as Tieling, Fushun, Benxi and Fuxin. As mentioned in the Letter from the Board, Liaoning Province has experienced fast economic growth and is a leader in economic development among the three provinces in northeast China and has a great demand for clean energy source such as natural gas. Besides, the above cities are relatively concentrated, which facilitates the transmission of natural gas products from this project via long-distance pipelines. With the acceleration of urbanisation, the reform in coal-fired boilers and the development of gas buses and industries using natural gas as raw material, the supply gap of natural gas in the above cities will grow bigger and bigger. The Company believes that following the completion of the Fuxin Coal-based Natural Gas Project, it will benefit from the growing demand for clean energy of Shenyang and the cities surrounding it which have experienced rapid economic development, thereby increasing the overall profitability of the Company. As mentioned above, the Keqi Coal-based Gas Project will use brown coal from Inner Mongolia Shengli Coal Mine East Unit 2, in which the Company has controlling interest, as raw materials and fuels, and the Fuxin Coal-based Gas Project will also use brown coal from Inner Mongolia Shengli Coal Mine East Unit 2 as its raw materials. As the Company owned and controlled Inner Mongolia Shengli Coal Mine East Unit 2, the brown coal from such coal mine could provide a reliable source of raw materials to the projects with cost advantage, and the Company is in a good position in arranging the main raw materials for the projects. Based on the data from CEIC, an independent data provider, the consumption of gas in Beijing and Liaoning Province has increased by approximately 152% and 90% (or a compound annual growth rate ("CAGR") of approximately 20% and 14%) respectively from year 2003 to year 2008. According to a report issued by an independent international research company in November 2009, the gas consumption in China is expected to increase by approximately 43% (or a CAGR of approximately 7%) from year 2009 to year 2014, but gas production is expected to increase by approximately 28% (or a CAGR of approximately 5%) from year 2009 to year 2014. Having considered the increase in gas consumption in Liaoning Province for the past few years, the acceleration of urbanisation, the reform in coal-fired boilers, the development of gas buses and industries using natural gas as raw material, as well as the expected increase in gas consumption in China for the next few years, we concur with the Directors' view that the Company will benefit from the Fuxin Coal-based Gas Project. Furthermore, having considered the increase in gas consumption in Beijing for the past few years, higher requirement for the quality of air environment in Beijing which might lead to high demand in clean energy such as natural gas, as well as the expected increase in gas consumption in China for the next few years, we concur with the Directors' view that the Company will benefit from the Keqi Coal-based Gas Project. The Company's investments in the Keqi Coal-based Gas Project and the Fuxin Coal-based Gas Project enable the Company to diversify its business structure into clean energy production, to enjoy synergistic benefits from its coal mine, and to leverage on the increasing trend on consumption for gas in Beijing and Liaoning province. In addition, as advised by the Directors, the Keqi Coal-based Gas Project is set up as a joint venture project with participation of other parties. This would enable the Company (i) to leverage on the capital edge and/or business connections and experience of the other parties to the Keqi Investment Agreement, such as the local connections in Beijing and experience in the city-gas pipeline business of Beijing Gas Group; (ii) to spread its risks associated with the project; and (iii) to allow the Company to diversify its resources into other viable projects. We agree with the Directors that CDC, Beijing Gas Group and Tianjin Jinneng are preferred joint venture partners for the Keqi Coal-based Gas Project given that the project is in an early stage of development, and the co-operations with CDC, Beijing Gas Group and Tianjin Jinneng are in interests of the Company and its shareholders as a whole. The Fuxin Coal-based Gas Project is set up as a joint venture project with CDC. This would enable the Company (i) to leverage on the capital edge of CDC; (ii) to spread its risks associated with the project; and (iii) to allow the Company to diversify its resources into other viable projects. We agree with the Directors that CDC is a preferred joint venture partner for the Fuxin Coal-based Gas Project given that the project is in an early stage of development, and the cooperation with CDC is in interests of the Company and its shareholders as a whole. 5. WORKING CAPITAL The total investment of Keqi Coal-based Gas Project is estimated to be approximately RMB25.71 billion and the ultimate registered capital of Keqi Coal-based Gas Company is approximately 30% of the total investment of the project, which is approximately RMB7.71 billion. Therefore, the ultimate registered capital to be contributed by the Group would be approximately RMB3,932.1 million (which is calculated based on 51% of RMB7.71 billion). The initial registered capital of Keqi Coal-based Gas Company is RMB100 million. Therefore, the initial registered capital contributed by the Group was approximately RMB51 million (which is calculated based on 51% of RMB100 million). The Group's contribution to the initial registered capital of Keqi Coal-based Gas Company will be funded by its internal resources. The total investment of Fuxin Coal-based Gas Project is estimated to be approximately RMB24.57 billion and the ultimate registered capital of Keqi Coal-based Gas Company is approximately 30% of the total investment of the project, which is approximately RMB7.37 billion. Therefore, the ultimate registered capital to be contributed by the Group would be approximately RMB6,633 million (which is calculated based on 90% of RMB7.37 billion). The initial registered capital of Keqi Coal-based Gas Company is RMB100 million. Therefore, the initial registered capital contributed by the Group was approximately RMB90 million (which is calculated based on 90% of RMB100 million). The Group's contribution to the initial registered capital of Fuxin Coal-based Gas Company will be funded by its internal resources. We have discussed with the Company on the impact of the capital contribution pursuant to the Keqi Investment Agreement and the Fuxin Investment Agreement on the working capital position of the Company and have reviewed the annual results of the Company for the year ended 31 December 2009. We note that the Company had cash of approximately RMB1,506,435,000 as at 31 December 2009. Furthermore, the amount of unutilised banking facilities of the Group is well in excess of the aggregate amount of the ultimate registered capital of Keqi Coal-based Gas Company and Fuxin Coal-based Gas Company which should be contributed by the Company (i.e. approximately RMB10,566.1 million). We concur with the view of the Directors that the Company has sufficient resources to finance its capital contribution obligations pursuant to the Keqi Investment Agreement and the Fuxin Investment Agreement. OPINION Having considered the principal factors and reasons described above, we are of the opinion that the terms of the Keqi Investment Agreement and the Fuxin Investment Agreement are on normal commercial terms and are fair and reasonable as far as the interests of the Independent Shareholders are concerned, and, from this perspective, the Keqi Investment Agreement and the Fuxin Investment Agreement are in the interests of the Company and its shareholders as a whole. Accordingly, we recommend the Independent Shareholders to vote in favour of the ordinary resolutions to be proposed at the General Meeting to approve the Keqi Investment Agreement and the Fuxin Investment Agreement.
