REASONS FOR AND BENEFITS OF ENTERING INTO THE ENTRUSTED LOAN CONTRACT

In order to ensure the replacement of due borrowings on schedule as well as to
replenish liquid capital in a timely manner, the Company provides the entrusted
loan of not exceeding RMB1 billion to Duolun Coal Chemical Company. The Company
is of the view that the entrusted loan, which will be primarily utilised by
Duolun Coal Chemical Company to replenish its liquidity loans and replace due
borrowings, is thus beneficial for the smooth progress of the production and
operation activities of Duolun Coal Chemical Company.

Considering the possible higher financial costs for Duolun Coal Chemical
Company to obtain the same loan from other commercial banks when compared with
the financial costs incurred by the Company to obtain the funding of the
entrusted loan, the Company considers that the overall capital costs to the
Group will be relatively reduced after the accounts of Duolun Coal Chemical
Company (being the subsidiary of the Company) are consolidated into the
accounts of the Company.

The Directors (including the independent non-executive Directors) are of the
view that the terms of the Entrusted Loan Contract are fair and reasonable,
have been entered into after arm's length negotiation between all parties
thereto and determined on normal commercial terms in ordinary and usual course
of business and is in the interests of the Company and its Shareholders as a
whole.
