Investor. This Agreement and each of the Transaction Documents are, or when executed and delivered by such Investor will be, valid and legally binding obligations of such Investor (assuming the due authorization, execution and delivery by other
parties thereto), enforceable against such Investor in accordance with its terms, except (i) as limited by applicable bankruptcy, insolvency, reorganization, moratorium, and other Laws of general application affecting enforcement of
creditors’ rights generally, and (ii) as limited by Laws relating to the availability of specific performance, injunctive relief, or other equitable remedies. 
 4.3 Purchase for Own Account. The Series A Preferred Shares purchased hereunder, and to be received by such Investor, if any, will be acquired for investment purposes for such Investor’s own
account or the account of one or more of such Investor’s Affiliates, not as a nominee or agent, and not with a view to the resale or distribution of any part thereof, and such Investor does not have any present intention of selling, granting
any participation in, or otherwise distributing the same. By executing this Agreement, such Investor further represents that it does not have any Contract with any Person to, directly or indirectly, sell, transfer or grant participations, with
respect to any of the Series A Preferred Shares, and has not solicited any Person for such purpose, and if such Investor is not a natural person then it further represents that it has not been organized for the purpose of acquiring the Series A
Preferred Shares. 
 4.4 Status of Investor. Such Investor is either (i) an “accredited investor” within the
meaning of U.S. Securities and Exchange Commission (“SEC”) Rule 501 of Regulation D, as presently in effect, under the Securities Act, or (ii) not a “U.S. person” as defined in Rule 902 of Regulation S of the
Securities Act and that any transfer or resale of the Series A Preferred Shares and the underlying Ordinary Shares will be in accordance with the provisions of said Regulation S or pursuant to an available exemption therefrom. 
 4.5 No Conflict; Certain Proceedings. Neither the execution and delivery of this Agreement and each of the Transaction Documents to which such
Investor is a party by such Investor nor the consummation or performance of the transaction contemplated hereby and thereby will give any Person the right to prevent, delay, or otherwise interfere with the transaction contemplated hereby pursuant to
any provision of such Investor’s Charter Documents, any legal requirement or order to which Investor may be subject, or any Contract to which such Investor is a party or by which such Investor may be bound. There is no pending Proceeding that
has been commenced against the Investor and that challenges, or may have the effect of preventing, delaying, making illegal, or otherwise interfering with the transaction contemplated hereby. To such Investor’s Knowledge, no such Proceeding has

the disclosure materials provided by the Warrantors under Section 3 of this Agreement.

and that under such Laws and applicable regulations such securities may be resold without registration under the Securities Act only in certain limited circumstances. Such Investor understands that the Securities have not been qualified or
registered under the Laws of any other jurisdiction and therefore may be viewed as restricted securities under any or all of such other applicable securities Laws.

 “THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR UNDER ANY OTHER

shall be conducted in Hong Kong under the Hong Kong International Arbitration Centre Administered Arbitration Rules in force when the Notice of Arbitration is submitted in accordance with the said Rules. The number of arbitrators shall be three. The
arbitration shall be conducted in the English language. 
 (iii) Each Party shall cooperate with the other in making full
disclosure of and providing complete access to all information and documents requested by the other in connection with such arbitration proceedings, subject only to any doctrine of legal privilege or any confidentiality obligations binding on such
Party. 
 (iv) The costs of arbitration shall be borne by the losing Party, unless otherwise determined by the arbitration
tribunal. 
 (v) When any dispute occurs and when any dispute is under arbitration, except for the matters in dispute, the
Parties shall continue to fulfill their respective obligations and shall be entitled to exercise their rights under this Agreement. 
 (vi) The award of the arbitration tribunal shall be final and binding upon the Parties, and the prevailing Party may apply to a court of competent jurisdiction for enforcement of such award. 
 (vii) Regardless of anything else contained herein, any Party shall be entitled to seek preliminary injunctive relief from any court of
competent jurisdiction pending the conclusion of the arbitration. 
 (viii) In order to facilitate the comprehensive resolution
of related disputes, and upon request of any Party to the arbitration proceeding, the arbitration tribunal may consolidate the arbitration proceeding with any other arbitration proceeding(s) involving any of the Parties relating to this Agreement or
any other Transaction Documents in connection therewith. The arbitration tribunal shall not consolidate such arbitrations unless it determines that (i) there are issues of fact or law common to the two

  

 31 

 
proceedings so that a consolidated proceeding would be more efficient than separate proceedings, and (ii) no party would be prejudiced as a result of such consolidation through undue delay
or otherwise. In the event of different rulings on this question by the arbitration tribunal constituted hereunder and the tribunal(s) constituted under any of the Transaction Agreements, the ruling of the tribunal constituted under this Agreement
shall prevail. 
 10.5 Notices. Any notice required or permitted pursuant to this Agreement shall be given in writing and shall be given
either personally or by sending it by courier service, fax, electronic mail or similar means to the address as set out in Schedule III (or at such other address as such Party may designate by fifteen (15) days’ advance written
notice to the other Parties given in accordance with this Section 10.5). Where a notice is given personally, delivery shall be deemed to have been effected on receipt (or when delivery is refused). Where a notice is sent by courier
service, service of the notice shall be deemed to be effected by properly addressing, pre-paying and sending through an internationally-recognized courier the notice, with a confirmation of delivery, and to have been effected on receipt (or when
delivery is refused). Where a notice is sent by fax or electronic mail, service of the notice shall be deemed to be effected by properly addressing, and sending such notice through a transmitting organization, with a written confirmation of
delivery, and to have been effected on the day the same is sent as aforesaid if sent during normal business hours of the recipient on a Business Day thereof and otherwise on the next Business Day thereof. 
 10.6 Rights Cumulative. Except as otherwise provided herein, each and all of the various rights, powers and remedies of a Party will be considered to
be cumulative with and in addition to any other rights, powers and remedies which such Party may have at law or in equity in the event of the breach of any of the terms of this Agreement. The exercise or partial exercise of any right, power or
remedy will neither constitute the exclusive election thereof nor the waiver of any other right, power or remedy available to such Party. 
 10.7 Fees and Expenses. The Company shall pay all of its own costs and expenses incurred in connection with the negotiation, execution, delivery and performance of this Agreement and other Transaction Documents and the transactions
contemplated hereby and thereby. If the transaction contemplated hereby is consummated, at the Closing, the Company shall pay or reimburse all costs and expenses incurred by the Investors in connection with the transactions contemplated by the
Transaction Documents (including without limitation the fees of O’Melveny & Myers LLP, counsel to the Lead Investors) up to a maximum of US$100,000. If any action at law or in equity is necessary to enforce or interpret the terms of
this Agreement, the prevailing Party shall be entitled to reasonable attorney’s fees, costs and necessary disbursements in addition to any other relief to which such Party may be entitled. 
 10.8 Finder’s Fee. Each Warrantor agrees, jointly and severally, to indemnify and hold harmless each Investor from any liability for any
commission or compensation in the nature of a finders’ fee (and the costs and expenses of defending against such liability or asserted liability) for which the Company or any of its officers, employees or representatives is responsible.

 10.9 Severability. In case any provision of the Agreement shall be invalid, illegal or unenforceable, the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or impaired thereby. If, however, any provision of this Agreement shall be invalid, illegal, or unenforceable under any such applicable Law in any jurisdiction, it shall, as
to such

  

 32 

 
jurisdiction, be deemed modified to conform to the minimum requirements of such Law, or, if for any reason it is not deemed so modified, it shall be invalid, illegal, or unenforceable only to the
extent of such invalidity, illegality, or limitation on enforceability without affecting the remaining provisions of this Agreement, or the validity, legality, or enforceability of such provision in any other jurisdiction. 
 10.10 Amendments and Waivers. Any term of this Agreement may be amended and the observance of any term of this Agreement may be waived (either
generally or in a particular instance and either retroactively or prospectively), only with the written consent of each of (i) the Company, (ii) the Major Shareholders, and (iii) the Lead Investors. Any amendment or waiver effected in
accordance with this paragraph shall be binding upon each of the Parties. 
 10.11 No Waiver. Failure to insist upon strict
compliance with any of the terms, covenants, or conditions hereof will not be deemed a waiver of such term, covenant, or condition, nor will any waiver or relinquishment of, or failure to insist upon strict compliance with, any right, power or
remedy hereunder at any one or more times be deemed a waiver or relinquishment of such right, power or remedy at any other time or times. 
 10.12 Delays or Omissions. No delay or omission to exercise any right, power or remedy accruing to any Party under this Agreement, upon any breach or default of any other Party under this Agreement, shall impair any such right, power
or remedy of such non-breaching or non-defaulting Party nor shall it be construed to be a waiver of any such breach or default, or an acquiescence therein, or of or in any similar breach or default thereafter occurring; nor shall any waiver of any
single breach or default be deemed a waiver of any other breach or default theretofore or thereafter occurring. Any waiver, permit, consent or approval of any kind or character on the part of any Party of any breach or default under this Agreement,
or any waiver on the part of any Party of any provisions or conditions of this Agreement, must be in writing and shall be effective only to the extent specifically set forth in such writing. All remedies, either under this Agreement or by Law or
otherwise afforded to any Party, shall be cumulative and not alternative. 
 10.13 No Presumption. The Parties acknowledge that each
Party has been represented by counsel in connection with this Agreement. Accordingly, any rule of law or any legal decision that would require interpretation of any claimed ambiguities in this Agreement against the Party that drafted it, has no
application and is expressly waived. If any claim is made by a Party relating to any conflict, omission or ambiguity in the provisions of this Agreement, no presumption or burden of proof or persuasion will be implied because this Agreement was
prepared by or at the request of any Party or its counsel.

 Re: Legal Opinion 
 We are lawyers qualified in the People’s Republic of China (the “PRC”) and are qualified to issue an opinion on the laws and
regulations of the PRC. 
 We are acting as the PRC counsel to Daqo New Energy Corp. (the “Company”), a company incorporated
under the laws of the Cayman Islands, in connection with the investment of Granite Global Ventures III L.P., GGV III Entrepreneurs Fund L.P., Venture Star Investment (HK) Limited, NewMargin Growth Fund, L.P., Siguler Guff BRIC Opportunities Fund,
LP, Siguler Guff BRIC Opportunities Fund (E), LP, Siguler Guff BRIC Opportunities Fund II, LP, Siguler Guff BRIC Opportunities Fund II (T), LP and Siguler Guff BRIC Opportunities Fund II (M), LP (collectively, the “Investors”) in
the Company by subscribing for the Company’s Series A Preferred Shares (the “Transaction”). 
 We have been requested,
pursuant to the terms of the Share Purchase Agreement (the “Share Purchase Agreement”) dated November 11, 2009 among the Company, Daqo Solar Energy North America, Chongqing Daqo New Energy Co., Ltd (“Chongqing
Daqo”), Nanjing Daqo New Energy Co., Ltd (“Nanjing Daqo”), Daqo New Material Co., Ltd (“Daqo New Material”), the individuals listed in Appendix I attached hereto (the “Major
Shareholders”), the entities listed in Schedule I-B thereto and the Investors, and the ancillary agreements, including the Investor Rights Agreement and the Indemnification Agreements (collectively, the “Transaction
Documents”), to give this opinion on, inter alia, (A) the legality of the ownership structure of the following entities: (i) Chongqing Daqo, (ii) Nanjing Daqo and (iii) Daqo New Material (collectively referred to
hereafter as the “PRC Group

 
Entities”), (B) the legality, validity and enforceability of the lease agreement entered into by and between Daqo New Material and Chongqing Daqo, which has come into effect
since January 1, 2009 (the “Lease Agreement”), (C) the legality of the transactions and business operations of the PRC Group Entities as described in the Transaction Documents, and (D) certain matters relating to the
Transaction Documents. 
 As used herein, (A) “PRC Law” means all applicable laws, regulations, rules, orders, decrees,
guidelines, judicial interpretations and other legislation of the PRC, in effect on the date of this opinion; (B) “PRC Authorities” means any national, provincial, governmental, regulatory or administrative authority, agency or
commission in the PRC, or any court, tribunal or any other judicial or arbitral body in the PRC; (C) “Approvals” means all approvals, consents, waivers, sanctions, certificates, authorizations, filings, disclosures,
registrations, exemptions, permissions, endorsements, annual inspections, qualifications, permits and licenses required by any PRC Authorities pursuant to any PRC Law; and (D) “Material Adverse Effect” has the meaning set forth
in the Share Purchase Agreement. 
 In so acting, we have examined the originals or copies, certified or otherwise identified to our
satisfaction, provided to us by the Company and such other documents, corporate records, certificates, Approvals and other instruments as we have deemed necessary for the purpose of rendering this opinion, including, without limitation, originals or
copies of the Transaction Documents and other agreements referred to hereunder and certificates issued by PRC Authorities or officers of the Company. 
 In examination of the documents and for the purpose of giving this opinion, we have assumed without further inquiry: 
  

	(a)	the genuineness of all signatures, seals and chops, the authenticity of all documents submitted to us as originals, and the conformity with the originals of all
documents submitted to us as copies; 

  

	(b)	the truthfulness, accuracy and completeness of all factual statements in the documents; and 

  

	(c)	that all parties other than the PRC Group Entities to the Transaction Documents have the requisite power and authority to enter into the Transaction Documents and to
perform their obligations thereunder, that and all parties other than the PRC Group Entities to the Transaction Documents have duly authorized, executed and delivered the relevant Transaction Documents and that none of the Transaction Documents has
been revoked, amended, varied, cancelled or supplemented as of the date of this opinion. 

  

 2 

 Based on the foregoing, we are of the opinion that: 
  

	1.	Each of the PRC Group Entities has been duly organized and is validly existing as a wholly foreign owned enterprise or domestic funded company with limited liability,

	7.	To the best of our knowledge after due inquiry, there are no pending or threatened legal, arbitration or administrative proceedings in the PRC by or against any of
Chongqing Daqo or Nanjing Daqo, or to which the property of any of them is or may be subject, and, if determined adversely against any of Chongqing Daqo or Nanjing Daqo, would individually or in the aggregate, be reasonably expected to have a
Material Adverse Effect. 

  

	8.	Chongqing Daqo and Nanjing Daqo own or otherwise have the legal right to use the patents and trademarks listed in Appendix II hereto (collectively, the
“Intellectual Property”) relating to their business. The trademark license contract by and among Daqo Group Co., Ltd., Chongqing Daqo and Nanjing Daqo date August 8, 2009 is legal, valid and enforceable in all respects under

the PRC; (ii) none of the Intellectual Property is subject to any outstanding order, judgment or ruling restricting the title to or use of such Intellectual Property in the PRC; and (iii) no security interests or other liens have been

 4 

	12.	Daqo Group Co., Ltd. and Chongqing Daqo has full legal right, authority and power to execute and deliver the Non-compete Agreement dated July 1, 2008 by and among
the Company, Daqo Group Co., Ltd. and Chongqing Daqo (the “Non-compete Agreement”). The Non-compete Agreement is valid, legal and enforceable under PRC Law. 

  

	13.	On August 8, 2006, six PRC regulatory agencies, namely, the PRC Ministry of Commerce, the State Assets Supervision and Administration Commission, the State
Administration for Taxation, the State Administration for Industry and Commerce, the State Administration of Foreign Exchange, and the China Securities Regulatory Commission (the “CSRC”), jointly adopted the Regulations on Mergers and
Acquisitions of Domestic Enterprises by Foreign Investors (the “M&A Rules”). The M&A Rules purport, among other things, to require offshore special purpose vehicles, or SPVs, formed for overseas listing purposes through
acquisitions of PRC domestic companies and controlled by the PRC companies or individuals, to obtain the approval of the CSRC prior to the listing their securities on an overseas stock exchange. On September 21, 2006, pursuant to the M&A
Rules and other PRC Laws, the CSRC, on its official website, promulgated relevant guidance with respect to the issues of listing and trading of domestic enterprises’ securities on overseas stock exchanges (together with the M&A Rules, the
“M&A Rules and Related Clarifications”), including a list of application materials with respect to the listing on overseas stock exchanges by SPVs. Based on our understanding of current PRC Laws and the interpretations and
implementations thereof as of the date hereof, (i) the CSRC has jurisdiction over the Company’s proposed initial public offering in the United States; (ii) the CSRC currently has not issued any definitive rules or interpretations
concerning whether the proposed initial public offering contemplated by the Company in the United States on Form F-1 is subject to the M&A Rules and Related Clarifications; and (iii) notwithstanding the above, given that the Company set up
Chongqing Daqo and Nanjing Daqo as green-field, wholly foreign owned subsidiaries in the PRC, the Company is not a special purpose vehicle formed for the purpose of acquiring a PRC domestic company. Therefore, the M&A Rules and Related
Clarifications are not applicable. As a result, it is not necessary for the Company to obtain any approval from the CSRC for its listing and trading of the Company’s ADSs on the New York Stock Exchange. 

  

	14.	The choice of Hong Kong law as the governing law of the Transaction Documents is a valid choice of law under the laws of the PRC and would be recognized and given
effect in any action brought before a court of competent jurisdiction in the PRC against any PRC Group Entity, except for those laws (a) which such court considers to be procedural in nature, (b) which are revenue or penal laws, or
(c) the application of which would be inconsistent with applicable public policy, as such term is interpreted under the laws of the PRC. 

  

 5 

	15.	Except as described in Section 3.4 of the Disclosure Schedule, the courts of the PRC would recognize a final and conclusive arbitral award obtained in accordance
with the Transaction Documents against any PRC Group Entity and would recognize and enforce such award without re-examination or re-litigation of any matter which is the substantive subject of such award, provided that such recognition and
enforcement will be conducted in accordance with the PRC Supreme People’s Court, Mutual Enforcement of Arbitration Awards between the Mainland China and the Hong Kong Special Administrative Region Arrangement. 

 This opinion is subject to the following qualifications: 
  

	(a)	This opinion, as it relates to the enforceability of the Transaction Documents or any other agreements to which any of the PRC Group Entities is a party, is subject to
(A) any applicable bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium or similar laws affecting creditors’ rights generally, (B) possible judicial or administrative actions or any PRC Law affecting creditors’
rights, and (C) certain equitable, legal or statutory principles affecting the enforceability of contractual rights generally under concepts of public interest, interests of the State, national security, reasonableness, good faith and fair
dealing, and applicable statutes of limitation. 

  

	(b)	This opinion relates only to PRC Law and we express no opinion as to any laws other than PRC Laws. PRC Law as used in this opinion refers to PRC Law currently in force
as of the date of this opinion and there is no guarantee that any of such PRC Law will not be changed, amended or revoked in the immediate future or in the longer term with or without retroactive effect. 

 This opinion is intended to be used in the context which is specifically referred to herein and each paragraph should be looked at as a whole and no part
should be extracted and referred to independently. 
 This opinion is delivered solely to you and solely for the purpose of and in connection
with the Transaction

 [    ]
November 2009 
 Dear Sirs, 
 We have
acted as counsel as to Cayman Islands law to Daqo New Energy Corp. (the “Company”) in connection with the issue by the Company of 29,714,103 convertible redeemable series A preference shares of US$0.0001 par value each (the
“Series A Preferred Shares”). 
 1 DOCUMENTS REVIEWED 
 We have reviewed originals, copies, drafts or conformed copies of the documents listed in Schedule 1 to this opinion. 
 2 ASSUMPTIONS 
 The following opinion
is given only as to, and based on, circumstances and matters of fact existing and known to us on the date of this opinion. This opinion only relates to the laws of the Cayman Islands which are in force on the date of this opinion. In giving this
opinion we have relied (without further verification) upon the completeness and accuracy of the Director’s Certificate, a copy of which is attached to this opinion. We have also relied upon the assumptions set out in Schedule 2 to this opinion,
which we have not independently verified. 
 3 QUALIFICATIONS 
 The opinions expressed below are subject to the qualifications set out in Schedule 3 to this opinion. 
 4 OPINIONS 
 Based upon, and subject to, the foregoing assumptions and qualifications, and having regard to such legal
considerations as we deem relevant, we are of the opinion that: 
  

	4.1	The Company has been duly incorporated as an exempted company with limited liability and is validly existing and in good standing under the laws of the Cayman Islands
and possesses the capacity to own its property and assets, to carry on its business in accordance with the Restated M&A and to sue and be sued in its own name. 

 

 

	4.2	The Company has the necessary corporate power and authority to enter into and perform its obligations under the Transaction Documents. The execution and delivery of the
Transaction Documents by the Company and the performance by the Company of its obligations thereunder will not violate the memorandum or articles of association of the Company nor any applicable law, regulation, order or decree in the Cayman
Islands. 

  

	4.3	The authorised share capital of the Company is US$50,000 divided into 460,000,000 ordinary shares of US$0.0001 par value (the “Ordinary Shares”) and
40,000,000 Series A Preferred Shares. The Ordinary Shares and the Series A Preferred Shares will have the rights, preferences, privileges and restrictions set forth in the Restated M&A. Based on our review of the register of members and the
corporate records of the Company, at the date hereof the issued and outstanding shares of the Company consist of 100,000,000 Ordinary Shares, which shares have been authorised and validly issued and, on the assumption that the contractual
subscription price therefore was fully paid in cash, which shares may properly be credited as fully paid under Cayman Islands law. Resolutions of the directors of the Company to keep unissued, pending exercise of options granted under the Company's
2009 Share Incentive Plan (the “SIP”) authorised but unissued Ordinary Shares in the capital of the Company to meet the purchase rights of options under the SIP (the “SIP Resolutions”) were validly passed on
[    ] 2009. 

  

	4.4	The Series A Preferred Shares, when issued and allotted in accordance with the terms of the Transaction Documents, the Resolutions and the Restated M&A, and when
entered on the register of members of the Company against the name of the holders thereof as such, and the Conversion Shares, when issued upon a conversion of the Series A Preferred Shares, will be validly issued as fully paid and non-assessable
(meaning that no further sums are required to be paid by the holders thereof in connection with the issue thereof) under Cayman Islands law and in accordance with the Resolutions and the Restated M&A: 

  

	 	(a)	assuming payment in full of the consideration set forth in the Subscription Agreement has been made and no requirement to pay additional consideration is contained in
any other document; and 

  

	 	(b)	subject to the satisfaction of any conditions or requirements set forth in the Subscription Agreement, Restated M&A or the Resolutions. 

 Upon entry on the register of members of the Company, the holders of the Series A Preferred Shares will be the registered holders of such
number of Series A Preferred Shares as noted against their names on such register of members. 
  

	4.5	The execution, delivery and performance of the Transaction Documents has been authorised by and on behalf of the Company and the Transaction Documents have been duly
executed and delivered on behalf of the Company and constitute the legal, valid and binding obligations of the Company enforceable in accordance with their terms. 

  

	4.6	No authorisations, consents, approvals, licences, validations or exemptions are required by law from any governmental authorities or agencies or other official bodies
in the Cayman Islands in connection with: 

  

	 	(a)	the creation, execution or delivery of the Transaction Documents by the Company; or 

  

 2 

	 	(b)	the performance by the Company of its obligations under any of the Transaction Documents, including without limitation the sale and issue of the Series A Preferred
Shares and the Conversion Shares pursuant to the Transaction Documents. 

  

	4.7	It is not necessary or desirable to ensure the enforceability in the Cayman Islands of the Transaction Documents that they be registered in any register kept by, or
filed with, any governmental authority or regulatory body in the Cayman Islands. However, to the extent that any of the Transaction Documents creates a charge over assets of the Company, the Company and its Directors are under an obligation to enter
such charge in the Register of Mortgages and Charges of the Company in accordance with section 54 of the Companies Law. While there is no exhaustive definition of a charge under Cayman Islands law, a charge normally has the following
characteristics: 

  

	 	(a)	it is a proprietary interest granted by way of security which entitles the chargee to resort to the charged property only for the purposes of satisfying some liability
due to the chargee (whether from the chargor or a third party); and 

  

	 	(b)	the chargor retains an equity of redemption to have the property restored to him when the liability has been discharged. 

 However, as the Transaction Documents are governed by the laws of New York, the question of whether they would possess these particular
characteristics would be determined under the laws of New York. 
  

	4.8	No taxes, fees or charges (other than stamp duty) are payable (either by direct assessment or withholding) to the government or other taxing authority in the Cayman
Islands under the laws of the Cayman Islands in respect of: 

  

	 	(a)	the execution or delivery of the Transaction Documents; 

  

	 	(b)	the enforcement of the Transaction Documents; 

  

	 	(c)	the issuance of the Series A Preferred Shares; or 

  

	 	(d)	payments made under, or pursuant to, the Transaction Documents. 

 The Transaction Documents will be subject to nominal stamp duty if they are executed in or brought into the Cayman Islands but will otherwise not be subject to stamp duty. The Cayman Islands currently
have no form of income, corporate or capital gains tax and no estate duty, inheritance tax or gift tax. 
  

	4.9	Based solely on our inspection of the Register of Writs and Other Originating process in the Grand Court of the Cayman Islands from the date of incorporation of the
Company there were no actions or petitions pending against the Company in the courts of the Cayman Islands as at close of business in the Cayman Islands on [    ] November 2009. 

  

 3 

	4.10	The courts of the Cayman Islands will observe and give effect to the choice of New York law as the governing law of the Transaction Documents. The submission in the
Transaction Documents to arbitration in the Hong Kong International Arbitration Centre in accordance with the Hong Kong International Arbitration Centre Administered Arbitration Rules is valid and binding upon the Company. 

 

	4.11	Foreign arbitration awards may be enforced in the Cayman Islands under the Foreign Arbitral Awards Enforcement Law, which applies where the arbitration award to be
enforced (the “Award”) was made in pursuance of an arbitration agreement in a state which is a party to the New York Convention on the Recognition of Enforcement of Foreign Arbitral Awards adopted by the 1958 United Nations
Conference on International Commercial Arbitration (the “Convention”). In general, the courts of the Cayman Islands will enforce an Award made under the Convention unless it is proved by the party against whom the Award was made
that: 

  

	 	(a)	a party to the arbitration agreement was under some incapacity; 

  

	 	(b)	the arbitration agreement was not valid under the law to which the parties subjected it or, in default, under the law of the jurisdiction where the Award was made;

  

	 	(c)	the Award was made in circumstances contrary to natural justice; 

  

	 	(d)	the Award dealt with a matter or matters not contemplated by or falling within the terms of the submission to arbitration or contained decisions on matters beyond the
scope of such submission; or 

  

	 	(e)	the composition of the arbitral authority or the arbitral procedure was not in accordance with the agreement of the parties or, in default of such agreement, with the
laws of the jurisdiction where the arbitration took place. 

 Enforcement of an Award made under the Convention may
also be refused by the courts of the Cayman Islands where the Award is in respect of a matter which is not capable of settlement by arbitration or where it would be contrary to the public policy of the Cayman Islands to enforce such an Award.

 A foreign arbitration award may also be enforced in the Cayman Islands pursuant to common law principles by action on the
Award or pursuant to the Arbitration Law by leave of the Cayman Islands court. 
  

	4.12	It is not necessary to ensure the legality, validity, enforceability or admissibility in evidence of the Transaction Documents that any document be filed, recorded or
enrolled with any governmental authority or agency or any official body in the Cayman Islands. 

  

	4.13	None of the parties to the Transaction Documents will be treated as resident, domiciled or carrying on or transacting business or subject to taxation in the Cayman
Islands or in violation of any Cayman Islands law solely by reason of the negotiation, preparation or execution of the Transaction Documents, or the entering into of or the exercise of their rights on the performance of their obligations under the
Transaction Documents. 

  

 4 

	4.14	The Company is not entitled to any immunity under the laws of the Cayman Islands, whether characterised as sovereign immunity or otherwise, from any legal proceedings
to enforce the Transaction Documents in respect of itself or its property. 

  

	4.15	The Restated M&A are consistent and in compliance with the Companies Law and do not conflict with any other applicable law, regulation, order or decree currently in
force in the Cayman Islands. Under the Companies Law, the Restated M&A bind the Company and its members to the same extent as if each member has subscribed his name and affixed his seal thereto. The Restated M&A have been duly adopted by the
Shareholders’ Resolutions and are in full force and effect. 

  

	4.16	It is not necessary or advisable in order for the Investors (as defined in the Share Purchase Agreement) to enforce its rights under the Transaction Documents,
including the exercise of remedies thereunder, that it be licensed, qualified or otherwise entitled to carry on business in the Cayman Islands. 

  

	4.17	There is no exchange control legislation under Cayman Islands law and accordingly there are no exchange control regulations imposed under Cayman Islands law.

 We express no view as to the commercial terms of the Transaction Documents or whether such terms represent the intentions of
the parties and make no comment with regard to the representations which may be made by the Company. 
 This opinion may be relied upon by the
addressees only. It may not be relied upon by any other person except with our prior written consent. 
  

	
	Yours faithfully

 6 

 SCHEDULE 2 
 Assumptions 
 We have relied upon the following assumptions, which we
have not independently verified: 
  

	1	the Transaction Documents are, or will be, legal, valid, binding and enforceable against all relevant parties in accordance with their terms under Hong Kong law and all
other relevant laws (other than the laws of the Cayman Islands); 

  

	2	the choice of the laws of New York as the governing law of the Transaction Documents has been made in good faith and would be regarded as a valid and binding selection
which will be upheld by any court sitting in New York and any other relevant jurisdiction (other than the Cayman Islands) as a matter of the laws of New York and all other relevant laws (other than the laws of the Cayman Islands);

  

	3	copy documents, conformed copies or drafts of documents provided to us are true and complete copies of, or in the final forms of, the originals;

  

	4	all signatures, initials and seals are genuine; 

  

	5	the power, authority and legal right of all parties under all relevant laws and regulations (other than, with respect to the Company, the laws of the Cayman Islands) to
enter into, execute, deliver and perform their respective obligations under the Transaction Documents; 

  

	6	there is nothing contained in the minute book or the corporate records of the Company (which we have not inspected) which would or might affect the opinions hereinafter
appearing; and 

  

	7	there is nothing under any law (other than the law of the Cayman Islands) which would or might affect the opinions hereinafter appearing. Specifically, we have made no
independent investigation of the laws of New York. 

  

 7 

 SCHEDULE 3 
 Qualifications 
 The opinions expressed above are subject to the
following qualifications: 
  

	1	The term “enforceable” as used in this opinion means that the obligations assumed by the Company under the Transaction Documents are of a type which
the courts of the Cayman Islands will enforce. It does not mean that those obligations will necessarily be enforced in all circumstances in accordance with their terms. In particular: 

  

	 	1.1	enforcement may be limited by bankruptcy, insolvency, liquidation, reorganisation, readjustment of debts or moratorium or other laws of general application relating to
or affecting the rights of creditors; 

  

	 	1.2	enforcement may be limited by general principles of equity. For example, equitable remedies such as specific performance may not be available, inter alia, where damages
are considered to be an adequate remedy; 

  

	 	1.3	where obligations are to be performed in a jurisdiction outside the Cayman Islands, they may not be enforceable in the Cayman Islands to the extent that performance
would be illegal under the laws of that jurisdiction; 

  

	 	1.4	the Cayman Islands court has jurisdiction to give judgment in the currency of the relevant obligation and statutory rates of interest payable upon judgments will vary
according to the currency of the judgment. If the Company becomes insolvent and is made subject to a liquidation proceeding, the Cayman Islands court will require all debts to be proved in a common currency, which is likely to be the
“functional currency” of the Company determined in accordance with applicable accounting principles. Currency indemnity provisions have not been tested, so far as we are aware, in the courts of the Cayman Islands;

  

	 	1.5	obligations to make payments that may be regarded as penalties will not be enforceable; 

  

	 	1.6	the courts of the Cayman Islands may decline to exercise jurisdiction in relation to substantive proceedings brought under or in relation to the Transaction Documents
in matters where they determine that such proceedings may be tried in a more appropriate forum; and 

  

	 	1.7	a company cannot, by agreement or in its articles of association, restrict the exercise of a statutory power and there exists doubt as to enforceability of any
provision in the Transaction Documents whereby the Company covenants not to exercise powers specifically given to its shareholders by the Companies Law (2009 Revision), as amended, of the Cayman Islands, including, without limitation, the power to
increase its authorised share capital, amend its memorandum and articles of association, or present a petition to a Cayman Islands court for an order to wind up the Company. 

  

	2	Cayman Islands stamp duty may be payable if the original Transaction Documents are brought to or executed in the Cayman Islands. 

  

 8 

	3	A certificate, determination, calculation or designation of any party to the Transaction Documents as to any matter provided therein might be held by a Cayman Islands
court not to be conclusive final and binding if, for example, it could be shown to have an unreasonable or arbitrary basis, or in the event of manifest error. 

  

	4	In principle a Cayman Islands court will award costs and disbursements in litigation in accordance with the relevant contractual provisions but there remains some
uncertainty as to the way in which the rules of the Grand Court will be applied in practice. Whilst it is clear that costs incurred prior to judgment can be recovered in accordance with the contract, it is likely that post-judgment costs (to the
extent recoverable at all) will be subject to taxation in accordance with Grand Court Rules Order 62. 

  

	5	We reserve our opinion as to the extent to which a Cayman Islands court would, in the event of any relevant illegality, sever the offending provisions and enforce the
remainder of the transaction of which such provisions form a part, notwithstanding any express provisions in this regard. 

  

	6	We make no comment with regard to the references to foreign statutes in the Transaction Documents.
