Pursuant to the Over-allotment Option, the International Underwriters will have the right, exercisable by the Overall Coordinators (on behalf of the International Underwriters) at any time from the Listing Date until 30 days after the last day for lodging applications under the Hong Kong Public Offering, to require the Company to issue up to an aggregate of 1,574,550 additional Offer Shares (representing approximately 15% of the Offer Shares initially being offered under the Global Offering assuming the Offer Size Adjustment Option is not exercised at all) or up to an aggregate of --- page 6 --- – 6 – 1,810,750 additional H Shares (representing approximately 15% of the Offer Shares initially available under the Global Offering assuming the Offer Size Adjustment Option is exercised in full), at the Offer Price under the International Offering to solely cover over-allocations in the International Offering, if any.
