4.11 Reallocation from the International Offering to the Hong Kong Public Offering: If the number of Hong Kong Offer Shares which are the subject of the Accepted Hong Kong Public Offering Applications exceeds the number of Hong Kong Offer Shares initially offered (a “Hong Kong Public Offering Over-Subscription”), then:

In the event of such reallocation, the number of Offer Shares available under the International Offering and the respective International Offering Underwriting Commitment of the International Underwriters may be reduced in such manner and

proportions as the Overall Coordinators may in their sole and absolute discretion determine;

4.11.2 if purchasers have been procured by the International Underwriters for all the International Offer Shares initially offered (the “International Offering Full or Over-subscription”) and the Hong Kong Public Offering Over-Subscription represents a subscription of (i) 15 times or more but less than 50 times, (ii) 50 times or more but less than 100 times, or (iii) 100 times or more, of the number of the Hong Kong Offer Shares initially available for subscription under the Hong Kong Public Offering, then Offer Shares shall be reallocated to the Hong Kong Public Offering from the International Offering so that the total number of Offer Shares available under the Hong Kong Public Offering shall be increased to 1,448,380, 1,931,180 and 2,413,960 Offer Shares, respectively, representing approximately 30% (in the case of (i)), 40% (in the case of (ii)) or 50% (in the case of (iii)), respectively, of the total number of Offer Shares initially available under the Global Offering (before any exercise of the Over-Allotment Option); and

In each of the above cases, the number of Offer Shares available under the International Offering and the respective International Offering Underwriting Commitments of the International Underwriters shall be reduced accordingly and the Hong Kong Underwriters will not be entitled to the Underwriting Commission referred to in Clause 6.1 in respect of the Offer Shares reallocated to the Hong Kong Public Offering.

In the event of such reallocation, the number of Unsold Hong Kong Offer Shares and the respective Hong Kong Public Offering Underwriting Commitments of the Hong Kong Underwriters shall be reduced in such manner and proportions as the Overall Coordinators may in their sole and absolute discretion determine, and any Hong Kong Offer Shares so reallocated from the Hong Kong Public Offering to the International Offering shall for all purposes (including any fee arrangements) be deemed to be

International Offer Shares and will be allocated to increase the International Offering Underwriting Commitment of all or any of the International Underwriters in such proportion as the Overall Coordinators may in their sole and absolute discretion determine. The Hong Kong Underwriters will not be entitled to the Underwriting Commission referred to in Clause 6.1 in respect of the Offer Shares reallocated to the International Offering.

4.13 Hong Kong Underwriters’ obligations cease: All obligations and liabilities of the Hong Kong Underwriters under this Agreement will cease and be fully discharged following payment by or on behalf of the Hong Kong Underwriters in accordance with Clause 4.9 or Clause 4.10 or where the Hong Kong Public Offering is fully subscribed or upon a Hong Kong Public Offering Over-Subscription having occurred (save in respect of any antecedent breaches under this Agreement). Further, none of the Overall Coordinators or any of the Hong Kong Underwriters shall be liable for any failure by any Hong Kong Underwriter (other than itself as Hong Kong Underwriter) to perform any of such other Hong Kong Underwriter’s obligations under this Agreement.

12.4 Conduct of claims: If any Proceeding is instituted involving any Indemnified Party in respect of which the indemnity provided for in this Clause 12 may apply, such Indemnified Party shall, subject to any restrictions imposed by any Law or obligation of confidentiality, promptly notify the Indemnifying Party in writing of the institution of such Proceeding, provided, however, that the omission to so notify the Indemnifying Party shall not relieve such Indemnifying Party from any liability which such Indemnifying Party may have to any Indemnified Party under this Clause 12 or otherwise. The Indemnifying Party may participate at its expense in the defence of such Proceeding including appointing counsel at its expense to act for it in such Proceeding; provided, however, that counsel to the Indemnifying Party shall not (except with the consent of any Indemnified Parties) also be counsel to the Indemnified Party.

Any settlement or compromise by any Indemnified Party, or any consent by any Indemnified Party to the entry of any judgement, in relation to any Proceeding shall be without prejudice to, and without (other than any obligations imposed on it by Law) any accompanying obligation or duty to mitigate the same in relation to, any Loss it may recover from, or any Proceeding it may take against, any of the Indemnifying Parties under this Agreement. The Indemnified Parties are not required to obtain consent from any of the Indemnifying Party with respect to such settlement or compromise. An Indemnifying Party shall be liable for any settlement or compromise by any Indemnified Party of, or any judgment consented to by any Indemnified Party with respect to, any pending or threatened Proceeding, whether effected with or without the consent of such Indemnifying Party, and agrees to indemnify and hold harmless the Indemnified Party from and against any loss or liability by reason of such settlement, compromise or consent judgement.

12.7 Costs: For the avoidance of doubt, the indemnity under this Clause 12 shall cover all costs, charges, fees and expenses which any Indemnified Party may suffer, incur or pay in disputing, investigating, responding to, defending, settling or compromising, or enforcing any settlement, compromise or judgment obtained with respect to, any Losses or any Proceedings to which the indemnity may relate and in establishing its right to indemnification under this Clause 12.

12.8 Payment on demand: All amounts subject to indemnity under this Clause 12 shall be paid by an Indemnifying Party as and when they are incurred within 15 Business Days of a written notice demanding payment being given to such Indemnifying Party by or on behalf of the relevant Indemnified Party.
