  • (a) to authorize the Company to provide Guarantee of an aggregate amount not exceeding US$2 billion to Yancoal International Resources;

• As at the date of this announcement, the Company has no overdue external guarantees;

• The Guarantee and the authorization to the Board in relation to the provision of the Guarantee are subject to approval by the shareholders of the Company at the general meeting.

1. Basic information of the guaranteed party

In order to establish a scientific and regulated assets management structure and provide multi-channels of overseas financing platforms, in 2011, the Company set up Yancoal International (Holding) Company Limited (" Yancoal International ") as its wholly-owned subsidiary with an aggregate amount of capital contribution of US$2.8 million in Hong Kong. Yancoal International further set up Yancoal International Resources as its wholly-owned subsidiary with an aggregate amount of capital contribution of US$0.6 million. Yancoal International Resources acts as one of the main overseas financing platforms of the Company.

As approved at the second extraordinary general meeting of the Company in 2012, the Company issued the US$1 billion corporate bonds which were listed on The Stock Exchange of Hong Kong Limited (the " Hong Kong Stock Exchange "). Yancoal International Resources acted as the bond issuer in such corporate bond issue. For details, please refer to the 2012 annual report of the Company published on the websites of the Shanghai Stock Exchange, the Hong Kong Stock Exchange and the Company.

As at 31 December 2012, the total assets of Yancoal International Resources were RMB6.205 billion, the total liabilities (including the liabilities created by the US$ corporate bonds issued which were equivalent to approximately RMB6.285 billion) were RMB6.330 billion, and the net assets were RMB -124 million. Since Yancoal International Resources did not carry out any operational business, its revenue in 2012 was nil. Its net profit amounted to RMB -128 million, which was mainly as a result of the payment of the underwriting fees and the provision of interest for the US$ corporate bonds.

2. Particulars of the Guarantee agreement and the object of the Guarantee

At this stage, the Company has not signed the Guarantee agreement. The Company will determine an appropriate method of financing based on market conditions and the financing business arrangement. During the term of the Guarantee, the Company will implement the Guarantee in strict compliance with the authorization granted by the shareholders of the Company at the general meeting.

3. Opinion of the Board

The directors of the Company (the " Director(s) ") (including the independent non-executive Directors) consider that the provision of Guarantee is in line with the operation needs of the Company, and since the guaranteed party is a whollyowned subsidiary of the Company, that the risks in association with the Guarantee can be effectively controlled and prevented. Therefore, the provision

of the Guarantee will not be detrimental to the interests of the Company and the shareholders as a whole.

4. Accumulative amounts of external guarantees and overdue guarantees

As at the date of this announcement, the accumulative amount of the external guarantees provided by the Company (all of which are guarantees provided by the Company to its wholly-owned subsidiaries or controlled subsidiaries) was RMB27.93 billion in total, representing approximately 62.53% of the audited net assets of the Company as at the end of 2012.
