None of our major shareholders have different voting
rights from our other shareholders.

As at March 31, 2012, 14,569,658 of our ordinary shares, representing 29.09% of our outstanding
ordinary shares, were held by a total of 24 holders of record with addresses in the US. As at the same date, 34,931,671 of our ADSs (representing 34,931,671 ordinary shares), representing 69.75% of our outstanding ordinary shares, were held by one
registered holder of record with addresses in and outside of the US. Since certain of these ordinary shares and ADSs were held by brokers or other nominees, the number of record holders in the US may not be representative of the number of beneficial
holders or where the beneficial holders are resident. All holders of our ordinary shares are entitled to the same voting rights.

We have
entered into a Registration Rights Agreement dated October 12, 2011, or the Registration Rights Agreement, pursuant to which we have granted, subject to certain conditions, to Warburg Pincus certain demand registration rights. These demand
rights entitle these shareholders to require us to use our reasonable efforts to prepare and file, on not more than two occasions, a shelf registration statement on Form F-3 or, if we are not eligible to file a registration statement on Form F-3, a
non-shelf registration statement on Form F-1, under the Securities Act. The request for registration must cover at least that number of shares with an aggregate proposed offering price, net of underwriting commissions, of at least US$2 million.
Pursuant to the Registration Rights Agreement, we have also granted, subject to certain conditions, to Warburg Pincus certain piggy-back registration rights entitling these shareholders to sell their ordinary shares in a registered offering of our
company. In connection with an underwritten offering pursuant to a registration under the Registration Rights Agreement, if, in the opinion of the managing underwriter, it is appropriate because of marketing and other factors, to limit the number of
shares to be included in the offering, then only that number of shares which the managing underwriter believes could be included in the offering would be included, with any shares proposed to be sold by our company having priority of inclusion in
the offering. We are entitled in certain circumstances, including the existence of material non-public information, to defer filing a registration statement pursuant to a demand request or suspend any sales pursuant to an effective registration
statement.



---

We have agreed to bear the expenses incurred in connection with such registrations, excluding underwriting
discounts and commissions and selling shareholders legal fees. We have also agreed, under certain circumstances, to indemnify these shareholders and the underwriters in connection with such registrations. These shareholders have agreed to
indemnify us and the underwriters in connection with any such registrations provided that their obligation to indemnify is limited to the amount of sale proceeds received by them.

Pursuant to the terms of the Registration Rights Agreement, we are prohibited from entering into any merger, consolidation or reorganization in which our company will not be the surviving corporation
unless the successor corporation agrees to assume the obligations and duties of the company under the Registration Rights Agreement.

These
registration rights will expire at the earlier of the date on which these shareholders cease to own any registrable shares (as defined in the Registration Rights Agreement) and the sixth anniversary of the Registration Rights Agreement.
The ordinary shares owned by these shareholders cease to be registrable shares when they are able to sell freely their shares without any restriction pursuant to Rule 144 of the Securities Act.

We have filed the shelf registration statement on Form F-3 (File No. 333-177250) on October 12, 2011 and amended it on November 22, 2011
pursuant to the Registration Rights Agreement.
