of CDC, shall enter into a Guarantee with the Bank to pledge 358,680,000 H

Investment, the Board announces that the Company provided the Counter Guarantee
in favour of Datang Overseas Investment on 31 March 2010, pursuant to which the
Company agreed to provide a counter guarantee in favour of Datang Overseas
