Definitions

Based on our understanding of the current PRC Laws, the ownership structures of the PRC Entities both currently and immediately after giving effect to the Offering, do not and will not violate applicable PRC Laws.

The M&A Rules, among other things, purport to require that an offshore special purpose vehicle controlled directly or indirectly by PRC companies or individuals and formed for purposes of overseas listing through acquisition of PRC domestic interests held by such PRC companies or individuals obtain the approval of the CSRC prior to the listing and trading of such special purpose vehicle’s securities on an overseas stock exchange. Based on our understanding of the current M&A Rules, it will not be required under the M&A Rules to submit an application to the CSRC for its approval of the Offering and the listing and trading of the ADSs on the NYSE. However, the interpretation and implementation of the M&A rules may be updated or revised, and our opinion stated above is subject to any new laws, rules and regulations or detailed implementations and interpretations in any form relating to the M&A Rules.

PRC courts may recognize and enforce foreign judgments in accordance with the requirements of the PRC Civil Procedures Law based either on treaties between PRC and the country where the judgment is made or on principles of reciprocity between jurisdictions. China does not have treaties providing for the reciprocal recognition and enforcement of judgments of courts with the United States, the Cayman Islands. In addition, according to the PRC Civil Procedures Law, the PRC courts will not enforce a foreign judgment if it is decided as having violated the basic principles of PRC laws or national sovereignty, security or public interest. Therefore, recognition and enforcement in China of judgments of a court in any of these jurisdictions may involves uncertainty or impossible.

The statements made in the Registration Statement under the caption “Taxation — People’s Republic of China Taxation” to the extent that the discussion states definitive legal conclusions under PRC tax laws and regulations, subject to the qualifications therein, constitute our opinion on such matters.

To our best knowledge after due and reasonable inquiries, the statements set forth in the Registration Statement under the captions “Permissions Required from the PRC Authorities for Our Operations and This Offering”, “Risk Factors”, “Use of Proceeds”, “Dividend Policy”, “Enforceability of Civil Liabilities”, “Management’s Discussion and Analysis of Financial Condition and Results of Operations”, “Business”, “Regulations” and “Taxation”(other than any factual data or description contained therein), to the extent such statements describe or summarize PRC legal or regulatory matters, or documents, agreements or proceedings governed by PRC Laws, fairly present or fairly summarize in all material respects the PRC legal and regulatory matters, documents, agreements or proceedings referred to therein; and do not omit to state any material fact necessary to make the statements; and in light of the circumstances under which they were made, are not misleading in any material respect.

This Opinion relates only to PRC Laws and we express no opinion as to any laws other than PRC Laws. We have made no investigation of, and do not express or imply any views on, the laws of any jurisdiction other than PRC, and we have assumed that no such other laws would affect our opinion expressed above.

This Opinion is confined to, and given on the basis of PRC Laws in effect on the date indicated above. There is no guarantee that any PRC Laws, or the interpretation thereof or enforcement therefor, will not be changed, amended or replaced in the immediate future or in the longer term with or without retrospective effect.

This Opinion is subject to (i) applicable bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium or similar PRC Laws affecting creditors’ rights generally, and (ii) possible judicial or administrative actions or any PRC Laws affecting creditors’ rights.

This Opinion is subject to the effects of (i) certain equitable, legal or statutory principles affecting the enforceability of contractual rights generally under the concepts of public interest, national security, good faith and fair dealing, applicable statutes of limitation; (ii) any circumstance in connection with the formulation, execution or performance of any legal documents that would be deemed materially mistaken, clearly unconscionable, fraudulent; (iii) judicial discretion with respect to the availability of injunctive relief, the calculation of damages, and other costs, the waiver of immunity from jurisdiction of any court or from legal process; and (iv) the discretion of any competent PRC legislative, administrative or judicial bodies in exercising their authority in connection with the interpretation, implementation and application of relevant PRC Laws.
