(a)
The Registrant's annual report on Form 20-F for the fiscal year ended December 31, 2013 filed with the Commission on April 9, 2014; and
(b)
The description of the Registrant's Class A ordinary shares and ADSs incorporated by reference in the Registrant's registration statement on Form 8-A (File No. 001-35126) filed with the Commission on
April 6, 2011, including any amendment and report subsequently filed for the purpose of updating that description.
All
documents subsequently filed by the Registrant pursuant to Sections 13(a), 13(c), 14 or 15(d) of the Securities Exchange Act of 1934 (the "Exchange Act"), after the date of this registration statement and prior to the filing of a

that a statement contained in this registration statement or in any other later filed document that also is or is deemed to be incorporated by reference modifies or supersedes such statement. Any such statement so modified or superseded will not be

Item 4.
Description of Securities
Not applicable.
Item 5.
Interests of Named Experts and Counsel
Not applicable.
Item 6.
Indemnification of Directors and Officers
Cayman Islands law does not limit the
extent to which a company's articles of association may provide for indemnification of directors and officers, except to the extent any such provision may be held by the Cayman Islands courts to be contrary to public policy, such as to provide
indemnification against civil fraud or the consequences of committing a crime. The Registrant's currently effective articles of association provide that the Registrant shall indemnify its directors and officers against actions, proceedings,
costs, charges, expenses, losses, damages or liabilities incurred or sustained by such persons in their capacity as such, except through their fraud, willful default or dishonesty.
2
Pursuant to the indemnification agreements, the form of which was filed as Exhibit 10.3 to the
Registrant's registration statement on Form F-1, as amended (File No. 333-173292), the Registrant has agreed to indemnify its directors and officers to the fullest extent permitted by law against risks and expenses incurred by such persons
in connection with claims made by reason of their being such a director or officer.
The Underwriting Agreement, the form of which was
filed as Exhibit 1.1 to the Registrant's registration statement on Form F-1, as amended (File No. 333-173292), also provides for indemnification of the Registrant and its directors and officers for certain losses, claims, damages and
liabilities, including liabilities arising under the Securities Act, but only to the extent that such liabilities are caused by information relating to the underwriters furnished to the Registrant in writing expressly for use in such registration
statement and certain other disclosure documents.
Insofar as indemnification for liabilities arising under the Securities Act may be
permitted to directors, officers or persons controlling the Registrant pursuant to the foregoing provisions, the Registrant has been informed that in the opinion of the Commission, such indemnification is against public policy as expressed in the
Securities Act and is therefore unenforceable.
The Registrant also maintains a directors and officers liability insurance policy for its
directors and officers.
Item 7.
Exemption From Registration Claimed
Not applicable.
Item 8.
Exhibits
See the Index to Exhibits attached hereto.
Item 9.
Undertakings
(a)
The undersigned Registrant hereby undertakes:
(1)
To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:
(i)
to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;
(ii)
to reflect in the prospectus any facts or events arising after the effective date of this registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a
fundamental change in the information set forth in this registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was
registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price
represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective Registration statement;
(iii)
to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;
provided
,
however
, that paragraphs (a)(1)(i) and (a)(1)(ii) above do not apply if the information required to
be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by
reference in this Registration Statement;
(2)
That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and
the offering of such securities at that time shall be deemed to be the initial
bona fide
offering thereof; and
(3)
To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
3
(b)
The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant's annual report pursuant to Section 13(a) or
Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference
in this registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(c)
Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise,
the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director,
officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
