Appendix: Resolution in relation to the provision of guarantee of RMB140 million for Hebei Suntien Guohua Gas Co., Ltd. (河北新天國化燃氣有限責任公司) ("Suntien Guohua") by the

Company based on the proportion of shareholding

Suntien Guohua is a joint venture between the Company and Shanxi Guohua Energy Co., Ltd. ("Shanxi

Guohua"), with the Company and Shanxi Guohua each holding 50% equity interest in Suntien Guohua. In order to repay the loans from HECIC Group Finance Company Limited (河北建投集團財務有限公司) and Sinopec Finance Co., Ltd. (中國石化財務有限責任公司), and to reduce the finance costs and adjust

the credit structure, Suntien Guohua intends to apply for a fixed asset loan of RMB280 million from China Construction Bank Corporation ("CCB"), and at the request by CCB, a guarantee of RMB140 million is required from each of the shareholders of Suntien Guohua based on the proportion of their shareholdings (the "Guarantee") with a guarantee period of 105 months. The principal details of the relevant guarantee agreement to be entered into by the Company in respect of the Guarantee are as follows.

1. Borrower: Suntien Guohua

1. Lending Bank: CCB Handan Ci County Sub-branch

1. Credit Amount: RMB140 million (IV) Guarantor: the Company

1. Type of Guarantee: guarantee with joint and several liabilities. (VI) Guarantee Amount and Currency: RMB140 million
   (VII) Loan and Guarantee Period: 105 months

Given that each of the applicable percentage ratios in respect of the Guarantee is less than 5%, the Guarantee is not subject to the relevant requirements under Chapter 14 of the Rules Governing the Listing of Securities on The Stock Exchange of Hong Kong Limited. However, in accordance with the relevant provisions of the Listing Rules of Shanghai Stock Exchange (the "A Share Listing Rules") and the Guidelines for Related Party Transactions of Companies Listed on the Shanghai Stock Exchange, Suntien Guohua is a connected corporate legal person of the Company and the Guarantee constitutes a connected transaction of the Company. Apart from the Guarantee, the balance of the guarantee provided by the Company for Suntien Guohua is RMB98 million. As the gearing ratio of Suntien Guohua exceeds 70%, pursuant to the A Share Listing Rules and the articles of association of the Company, the Guarantee is required to be proposed to the general meeting of the Company for consideration.

3

The board of directors of the Company (the "Board") is of the view that: the Guarantee is to meet the capital requirements of Suntien Guohua in order to ensure its normal operation, which is beneficial to the shareholders to obtain better investment returns. Suntien Guohua is in a healthy asset position, normal production and operation, and has good business development prospects and debt servicing capability. The risk of the Guarantee to be provided by the Company for Suntien Guohua based on the proportion of shareholding is controllable and the Guarantee will not affect the Company's ability to continue its business and will not harm the interests of the Company and its shareholders.

The Board further considers that the supplemental resolution in relation to the Guarantee is in the interests of the Company and its shareholders as a whole and therefore recommends the shareholders of the Company to vote in favour of the supplemental resolution.
