VOLUNTARY ANNOUNCEMENT REGARDING
COALBED METHANE RESOURCES EXPLORATION AND DEVELOPMENT
COOPERATION SUPPLEMENTAL AGREEMENT

Reference is made to the announcement and circular (the “Circular”) both dated 3 August 2012 of CNOOC Limited (the “Company”) in respect of the connected transaction relating to the Coalbed Methane Resources Exploration and Development Cooperation Agreement (the “Cooperation Agreement”) entered into between CNOOC China, a direct wholly owned subsidiary of the Company,  and CUCBM on 3 August 2012. Unless the context requires otherwise, terms defined in the Circular should have the same meanings when used herein.

The Company has been informed by CUCBM that it is unable to fulfill its obligations under the Cooperation Agreement in respect of four CBM blocks (the “Relevant Blocks”) which form part of the Contract Areas. As a result, CNOOC China and CUCBM entered into a supplemental agreement on 10 October 2013, pursuant to which (i) the Relevant Blocks will be excluded from the Contract Areas; and (ii) CUCBM will indemnify in full CNOOC China against any related loss, the amount of which will be determined by a third party appraising firm appointed by both parties.

The Budgeted Expenses originally allocated to the Relevant Blocks were approximately RMB433.6 million. As of the date of this announcement, CNOOC China has incurred expenses of approximately RMB84.7 million on the Relevant Blocks, which will be reimbursed by CUCBM. CNOOC China will not incur any further expenditure on the Relevant Blocks. As the Relevant Blocks are still at preliminary exploration stage, no revenue has been generated and it is expected that the exclusion of the Relevant Blocks from the Contract Areas will not materially affect the expected profit in relation to the Cooperation Agreement.

In light of the above, the Company is of the view that the entering into of the supplemental agreement does not constitute a material change to the terms of the Cooperation Agreement.
