This announcement is for information purposes only and does not constitute an offer or an invitation to induce an offer by any person to acquire, purchase or subscribe for securities. This announcement is not a prospectus. Potential investors should read the Prospectus for detailed information about the Hong Kong Public Offering and the International Offering (collectively, the "Global Offering") described below before deciding whether or not to invest in the Offer Shares.

This announcement is not for release, publication, distribution, directly or indirectly, in or into the United States (including its territories and possessions, any state of the United States and the District of Columbia) or other jurisdiction where such distribution is prohibited by law. This announcement does not constitute or form a part of any offer to sell or solicitation to purchase or subscribe for securities in Hong Kong, the United States or in any other jurisdictions. The H Shares have not been, and will not be, registered under the United States Securities Act of 1933, as amended from time to time (the "U.S. Securities Act") or any state securities laws of the United States. The securities may not be offered or sold in the United States except pursuant to an effective registration statement or in accordance with an available exemption from, or in a transaction not subject to, the registration requirements of the U.S. Securities Act. There will be no public offer of securities of the Company in the United States. The H Shares are being offered and sold only in offshore transactions within the meaning of and in reliance on Regulation S under the U.S. Securities Act.

In connection with the Global Offering, China International Capital Corporation Hong Kong Securities Limited, as stabilizing manager (the "Stabilizing Manager"), its affiliates or any person acting for it and on behalf of the Underwriter(s), may over-allocate or effect transactions with a view to stabilizing or supporting the market price of the H Shares at a level higher than that which might otherwise prevail for a limited period after the Listing Date. However, there is no obligation on the Stabilizing Manager, its affiliates or any person acting for it, to conduct any such stabilizing action, which, if commenced, will be done at the sole and absolute discretion of the Stabilizing Manager, its affiliates or any person acting for it, and may be discontinued at any time. Any such stabilizing action is required to be brought to an end on the 30th day after the last day for the lodging of applications under the Hong Kong Public Offering. Such stabilization action, if commenced, may be effected in all jurisdictions where it is permissible to do so, in each case in compliance with all applicable laws, rules and regulatory requirements, including the Securities and Futures (Price Stabilizing) Rules, as amended, made under the Securities and Futures Ordinance (Chapter 571 of the Laws of Hong Kong).

Potential investors should be aware that stabilizing action cannot be taken to support the price of the H Shares for longer than the stabilization period which begins on the Listing Date, and is expected to expire on the 30th day after the last day for the lodging of applications under the Hong Kong Public Offering. After this date, no further stabilizing action may be taken, demand for the H Shares, and therefore the price of the H Shares, could fall.
