At the extraordinary general meeting, you will be asked to consider and vote upon a proposal to authorize and approve the agreement and plan of merger dated February 21, 2013, among the Company, WSP OCTG GROUP Ltd. ("WSP OCTG") and JM OCTG GROUP Ltd. ("JM OCTG"), as amended on August 15, 2013, and as further amended and assigned on March 19, 2014 by WSP OCTG to Wuxi Heavy Industries, Ltd. ("Parent") and by JM OCTG to WHI Acquisitions, Ltd. ("Merger Sub") (such agreement, as so amended and assigned, the "merger agreement"), the plan of merger required to be filed with the Registrar of Companies of the Cayman Islands, substantially in the form attached as Annex A to the merger agreement (the "plan of merger") and the transactions contemplated by the merger agreement, including the merger (the "merger"). Copies of the merger agreement and the plan of merger are attached as Annex A to the accompanying proxy statement.

Under the terms of the merger agreement, Merger Sub, a company wholly-owned by Parent, will be merged with and into the Company, with the Company continuing as the surviving company after the merger (the "merger"). Merger Sub is a Cayman Islands company with limited liability formed solely for purposes of the merger. Parent is a Cayman Islands company with limited liability which, at the effective time of the merger, will be beneficially owned by (i) General Transactions, Inc., an exempted company with limited liability incorporated under the laws of the British Virgin Islands ("General Transactions"), which is beneficially owned by Mr. Sergey Alexandrovich Borovskiy ("Mr. Borovskiy"), (ii) Expert Master Holdings Limited, a British Virgin Islands company ("EMH"), which is wholly-owned by Mr. Longhua Piao, chairman of the board of directors and chief executive officer of the Company ("Mr. Piao"), and (iii) UMW China Ventures (L) Ltd., a company incorporated in Malaysia ("UMW China"), which is wholly-owned by UMW Petropipe (L) Ltd.

EMH, Mr. Piao, and UMW are collectively referred to herein as the "Rollover Shareholders." Parent, Merger Sub and General Transactions, together with the Rollover Shareholders, are collectively referred to as the "Buyer Group." As of the date of the proxy statement, the Rollover Shareholders together own 150,000,000 ordinary shares, representing approximately 73.4% of the Company's outstanding ordinary shares, referred to herein as the "Shares." If the merger is completed, the Company will continue its operations as a privately held company and will be beneficially owned by the Buyer Group. As a result of the merger, the Company's American depositary shares ("ADSs"), each representing ten Shares, will no longer be listed on the New York Stock Exchange (the "NYSE"), and the American depositary shares program for the ADSs will terminate.

If the merger is completed, at the effective time of the merger, each outstanding Share (including Shares represented by ADSs), other than (a) Shares owned by Parent, Merger Sub or the Company (as treasury Shares, if any), or by any direct or indirect wholly-owned subsidiary of Parent, Merger Sub

The Excluded Shares other than the Dissenting Shares will be cancelled and cease to exist for no consideration. The Dissenting Shares will be cancelled and cease to exist for the fair value of the Shares as described in more detail below.

The Rollover Shareholders have entered into a rollover agreement with WSP OCTG and JM OCTG, which was amended and assigned by WSP OCTG and JM OCTG to Parent and Merger Sub, respectively, on March 19, 2014 (the "rollover agreement") pursuant to which they have agreed to contribute to Parent the Shares owned by them, representing approximately 73.4% of the outstanding Shares as of March 19, 2014 (the "Rollover Shares"), in exchange for certain equity interests in Parent at the same price per share of Parent as is paid by General Transactions at the closing of the merger, such that each of the Rollover Shareholders, following the closing, will own an equity interest in Parent corresponding to its percentage ownership in the Company prior to the effective time of the merger.

An independent committee of the board of directors of the Company, composed solely of directors unrelated to the Buyer Group or the management of the Company (the "Special Committee"), has reviewed and considered the terms and conditions of the merger agreement, the plan of merger and the transactions contemplated by the merger agreement, including the merger. The Special Committee unanimously (a) determined that the merger agreement is fair to and in the best interests of the Company and its unaffiliated security holders, (b) declared it advisable to enter into the merger agreement, (c) recommended that the board of directors of the Company authorize and approve the merger agreement, the plan of merger and the transactions contemplated by the merger agreement, including the merger, and (d) recommended that the board of directors of the Company direct that the authorization and approval of the merger agreement, the plan of merger and the transactions contemplated by the merger agreement, including the merger, be submitted to a vote at an extraordinary general meeting of the shareholders of the Company with the recommendation of the board of directors that the shareholders of the Company authorize and approve by way of a special resolution the merger agreement, the plan of merger and the transactions contemplated by the merger agreement, including the merger.

On February 21, 2013, the board of directors of the Company (with Messrs. Longhua Piao, Syed Hisham bin Syed Wazir and Xizhong Xu, the directors related to the Rollover Shareholders or the management of the Company, abstaining), after carefully considering all relevant factors, including the unanimous determination and recommendation of the Special Committee, (a) determined that it is fair to and in the best interests of the Company and its unaffiliated security holders, and declared it advisable, to enter into the merger agreement, (b) authorized and approved the execution, delivery and performance of the merger agreement, the plan of merger and the other documents referred to in the merger agreement and the consummation of the transactions contemplated by the merger agreement, including the merger, and (c) resolved to direct that the authorization and approval of the merger agreement, the plan of merger and the transactions contemplated by the merger agreement, including the merger, be submitted to a vote at an extraordinary general meeting of the shareholders of the Company.

After careful consideration and upon the unanimous recommendation of the Special Committee of the board of directors of the Company, the Company's board of directors (with Messrs. Longhua Piao, Syed Hisham bin Syed Wazir and Xizhong Xu, the directors related to the Rollover Shareholders or

the management of the Company, abstaining) recommends that you vote FOR the proposal to authorize and approve the merger agreement, the plan of merger and the transactions contemplated by the merger agreement, including the merger, and FOR the proposal to adjourn the extraordinary general meeting in order to allow the Company to solicit additional proxies in the event that there are insufficient proxies received at the time of the extraordinary general meeting, as originally scheduled, to pass the special resolution.

The accompanying proxy statement provides detailed information about the merger and the extraordinary general meeting. We encourage you to read the entire document and all of the attachments and other documents referred to or incorporated by reference herein carefully. You may also obtain more information about the Company from documents the Company has filed with the Securities and Exchange Commission (the "SEC"), which are available for free at the SEC's website www.sec.gov.

As of the date of the proxy statement, the Rollover Shareholders together own 150,000,000 ordinary shares of the Company, representing approximately 73.4% of the Company's Shares. Accordingly, the Rollover Shareholders together have sufficient votes to constitute a quorum for the extraordinary general meeting and authorize and approve the merger agreement, the plan of merger and the transactions contemplated by the merger agreement, including the merger, at the extraordinary general meeting. The Rollover Shareholders have agreed to vote, or cause to be voted, all Shares that they own in favor of the authorization and approval of the merger agreement and the transactions contemplated by the merger agreement pursuant to a voting agreement dated February 21, 2013 by and among WSP OCTG, JM OCTG, EMH and Mr. Piao, as amended and assigned on March 19, 2014, by WSP OCTG to Parent and by JM OCTG to Merger Sub, and a voting agreement dated February 21, 2013, by and among WSP OCTG, JM OCTG and UMW China, as amended and assigned on March 19, 2014, by WSP OCTG to Parent and by JM OCTG to Merger Sub.

Whether or not you plan to attend the extraordinary general meeting, please complete the enclosed proxy card, in accordance with the instructions set forth on your proxy card, as promptly as possible. The deadline to lodge your proxy card is , 2014 at p.m. (Hong Kong time). Each shareholder has one vote for each Share held as of the close of business in New York City on , 2014, or the share record date. Voting at the extraordinary general meeting will take place by poll, as the chairman of the Company's board of directors has undertaken to demand poll voting at the meeting.

As the record holder of the Shares represented by ADSs, JPMorgan Chase Bank, N.A., in its capacity as ADS depositary, will endeavor to vote (or will endeavor to cause the vote of) the Shares it holds on deposit at the extraordinary general meeting in accordance with the voting instructions timely received from holders of ADSs at the close of business in New York City on , 2014, the ADS record date. The ADS depositary must receive such instructions no later than p.m. (New York City time) on , 2014.

Pursuant to the Deposit Agreement, the ADS depositary will not exercise any voting discretion. As such, the ADS depositary will not issue any discretionary proxy to vote any Shares represented by ADSs for which the ADS depositary does not timely receive valid voting instructions from the ADS holders as of the ADS record date, the close of business in New York City on , 2014.

Holders of ADSs will not be able to attend the extraordinary general meeting unless they cancel their ADSs and become holders of Shares prior to the close of business in New York City on , 2014, the share record date. ADS holders who wish to cancel their ADSs need to make arrangements to surrender the ADSs to the ADS depositary for cancellation before the close of business in New York City on , 2014, together with (a) delivery instructions for the corresponding Shares (name and address of person who will be the registered holder of the Shares)

and (b) payment of the ADS cancellation fees ($0.05 per ADS to be cancelled) and any applicable taxes. In addition, prior holders of ADSs that attend the meeting will be required to certify at the meeting to the Company that such former holder either (i) held the ADSs as of the applicable ADS record date for the extraordinary general meeting and has not given, and will not give, voting instructions to the ADS depositary as to the ADSs being cancelled, or has given voting instructions to the ADS depositary as to the ADSs being cancelled but undertakes not to vote the corresponding Shares at the extraordinary general meeting, or (ii) did not hold the ADSs as of the applicable ADS record date for the extraordinary general meeting and undertakes not to vote the corresponding Shares at the extraordinary general meeting. If you hold your ADSs in a brokerage, bank or nominee account, please contact your broker, bank or nominee to find out what actions you need to take to instruct the broker, bank or nominee to cancel the ADSs on your behalf. Upon cancellation of the ADSs, the ADS depositary will request for J.P. Morgan Chase Bank N.A.—Hong Kong Branch (DCC), the custodian holding the Shares, to request the transfer in the registration of the Shares to the former ADS holder (or a person designated by the former ADS holder). If after the registration of Shares in your name you wish to receive a certificate evidencing the Shares registered in your name, you will need to request the registrar of the Shares to issue and mail a certificate to your attention.

If the merger is not completed, the Company would continue to be a public company in the U.S. and the Company's ADSs would continue to be listed on the NYSE. The Company's Shares are not listed and cannot be traded on any stock exchange other than the NYSE, and in such case only in the form of ADSs. As a result, if you have cancelled your ADSs to attend the extraordinary general meeting and the merger is not completed and you wish to be able to sell your Shares on a stock exchange, you would need to deposit your Shares into the Company's American depositary shares program for the issuance of the corresponding number of ADSs, subject to the terms and conditions of applicable law and the Deposit Agreement, including, among other things, payment of relevant fees of the ADS depositary for the issuance of ADSs ($0.05 per ADS issued) and any applicable stock transfer taxes (if any) and related charges pursuant to the Deposit Agreement.

Shareholders who dissent from the merger will have the right to receive payment of the fair value of their Shares if the merger is completed, but only if they deliver to the Company, before the vote is taken at the extraordinary general meeting, a written objection to the merger and subsequently comply with all procedures and requirements of Section 238 of the Cayman Islands Companies Law for the exercise of dissenter rights, which is attached as Annex C to the accompanying proxy statement. The fair value of your Shares as determined under that statute could be more than, the same as, or less than the merger consideration you would receive pursuant to the merger agreement if you do not exercise dissenter rights with respect to your Shares.

ADS HOLDERS WILL NOT HAVE THE RIGHT TO DISSENT FROM THE MERGER AND RECEIVE PAYMENT OF THE FAIR VALUE OF THE SHARES UNDERLYING THEIR ADSS. THE ADS DEPOSITARY WILL NOT ATTEMPT TO EXERCISE ANY DISSENTER RIGHTS WITH RESPECT TO ANY OF THE SHARES THAT IT HOLDS, EVEN IF AN ADS HOLDER REQUESTS THE ADS DEPOSITARY TO DO SO. ADS HOLDERS WISHING TO EXERCISE DISSENTER RIGHTS MUST SURRENDER THEIR ADSS TO THE ADS DEPOSITARY, PAY THE ADS DEPOSITARY'S FEES REQUIRED FOR THE CANCELLATION OF THE ADSS, PROVIDE INSTRUCTIONS FOR THE REGISTRATION OF THE CORRESPONDING SHARES, AND CERTIFY TO THE COMPANY THAT THEY HAVE NOT GIVEN, AND WILL NOT GIVE, VOTING INSTRUCTIONS AS TO THE ADSS (OR, ALTERNATIVELY, THAT THEY WILL NOT VOTE THE SHARES) BEFORE THE CLOSE OF BUSINESS IN NEW YORK CITY ON , 2014, AND BECOME REGISTERED HOLDERS OF SHARES BY THE CLOSE OF BUSINESS IN NEW YORK CITY ON , 2014. THEREAFTER, SUCH FORMER ADS HOLDERS MUST COMPLY WITH THE PROCEDURES AND REQUIREMENTS FOR EXERCISING DISSENTER RIGHTS WITH RESPECT TO THE SHARES UNDER SECTION 238 OF THE CAYMAN ISLANDS COMPANIES LAW. IF THE MERGER IS NOT COMPLETED, THE COMPANY WOULD CONTINUE TO BE A PUBLIC COMPANY IN THE U.S. AND THE COMPANY'S ADSS WOULD CONTINUE TO BE LISTED ON THE NYSE. THE COMPANY'S SHARES ARE NOT LISTED AND CANNOT BE

TRADED ON ANY STOCK EXCHANGE OTHER THAN THE NYSE, AND IN SUCH CASE ONLY IN THE FORM OF ADSS. AS A RESULT, IF YOU HAVE CANCELLED YOUR ADSS TO EXERCISE YOUR DISSENTER RIGHTS AND THE MERGER IS NOT COMPLETED AND YOU WISH TO BE ABLE TO SELL YOUR SHARES ON A STOCK EXCHANGE, YOU WOULD NEED TO DEPOSIT YOUR SHARES INTO THE COMPANY'S AMERICAN DEPOSITARY SHARES PROGRAM FOR THE ISSUANCE OF THE CORRESPONDING NUMBER OF ADSS, SUBJECT TO THE TERMS AND CONDITIONS OF APPLICABLE LAW AND THE DEPOSIT AGREEMENT, INCLUDING, AMONG OTHER THINGS, PAYMENT OF RELEVANT FEES OF THE ADS DEPOSITARY FOR THE ISSUANCE OF ADSS ($0.05 PER ADS ISSUED) AND ANY APPLICABLE STOCK TRANSFER TAXES (IF ANY) AND RELATED CHARGES PURSUANT TO THE DEPOSIT AGREEMENT.

Neither the SEC nor any state securities regulatory agency has approved or disapproved the merger, passed upon the merits or fairness of the merger or passed upon the adequacy or accuracy of the disclosure in this letter or in the accompanying notice of the extraordinary general meeting or proxy statement. Any representation to the contrary is a criminal offense.

If after registration of Shares in your name, you wish to receive a certificate evidencing the Shares registered in your name, you will need to request the registrar of the Shares to issue and mail a certificate to your attention.

Shareholders who dissent from the merger will have the right to receive payment of the fair value of their Shares if the merger is completed, but only if they deliver to the Company, before the vote is taken, a written objection to the merger and subsequently comply with all procedures and requirements of Section 238 of the Cayman Islands Companies Law for the exercise of dissenter rights. The fair value of your Shares as determined under that statute could be more than, the same as, or less than the merger consideration you would receive pursuant to the merger agreement if you do not exercise dissenter rights with respect to your Shares.

ADS HOLDERS WILL NOT HAVE THE RIGHT TO DISSENT FROM THE MERGER AND RECEIVE PAYMENT OF THE FAIR VALUE OF THE SHARES UNDERLYING THEIR ADSS. THE ADS DEPOSITARY WILL NOT ATTEMPT TO EXERCISE ANY DISSENTER RIGHTS WITH RESPECT TO ANY OF THE SHARES THAT IT HOLDS, EVEN IF AN ADS HOLDER REQUESTS THE ADS DEPOSITARY TO DO SO.

THEREAFTER, SUCH FORMER ADS HOLDERS MUST COMPLY WITH THE PROCEDURES AND REQUIREMENTS FOR EXERCISING DISSENTER RIGHTS

WITH RESPECT TO THE SHARES UNDER SECTION 238 OF THE CAYMAN ISLANDS COMPANIES LAW.

We encourage you to read the section of this proxy statement entitled "Dissenter Rights" as well as Annex C to this proxy statement carefully and to consult your Cayman Islands legal counsel if you desire to exercise your dissenter rights.

The purpose of the merger is to enable Parent to acquire 100% control of the Company in a transaction in which the Company's shareholders, other than the holders of Excluded Shares, will be cashed out in exchange for $0.32 per Share (or $3.20 per ADS), so that Parent will bear the rewards and risks of the sole ownership of the Company after the merger, including any future earnings and growth of the Company as a result of improvements to the Company's operations or acquisitions of other businesses. Please see "Special Factors—Purpose and Reasons of the Buyer Group for the Merger" beginning on page 61 for additional information.

ADSs representing the Shares are currently listed on the NYSE under the symbol "WH." It is expected that, immediately following the completion of the merger, the Company will cease to be a publicly traded company and will instead become a privately-held company directly owned by Parent and indirectly, through Parent, by General Transactions and the Rollover Shareholders. Following the completion of the merger, our ADSs will no longer be listed on the NYSE or any other securities exchange or quotation system, and price quotations with respect to sales of the ADSs in the public market will no longer be available. In addition, registration of the ADSs and the underlying Shares under the Exchange Act may be terminated upon the Company's application to the SEC if the Shares are not listed on a national securities exchange and there are fewer than 300 record holders of the Shares. Ninety days after the filing of Form 15 in connection with the completion of the merger or such longer period as may be determined by the SEC, registration of the ADSs and the underlying Shares under the Exchange Act will be terminated and the Company will no longer be required to file periodic reports with the SEC. Furthermore, following the completion of the merger, the American depositary shares program for the ADSs will terminate. Please see "Special Factors—Effects of the Merger on the Company" beginning on page 61 for additional information.

Following the completion of the merger and the termination of registration of the Company's ADSs and underlying Shares under the Exchange Act, the Buyer Group anticipates that the Company will continue to conduct its operations substantially as they are currently being conducted, except that the Company will cease to be a publicly traded company and will instead be a wholly-owned subsidiary of Parent. The Company will no longer be subject to the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or the compliance and reporting requirements of the NYSE and the related direct and indirect costs and expenses.

The Buyer Group has advised the Company that, except for the transactions contemplated by the merger agreement and transactions already under consideration by the Company, the Buyer Group does not have any current plans, proposals or negotiations that relate to or would result in any of the following:

Recommendations of the Special Committee and our Board of Directors (Page 38)

The Special Committee unanimously (a) determined that the merger agreement is fair to and in the best interests of, the Company and its unaffiliated security holders, (b) declared it advisable to enter into the merger agreement, (c) recommended that the board of directors of the Company authorize and approve the merger agreement, the plan of merger and the transactions contemplated by the merger agreement, including the merger, and (d) resolve to recommend the authorization and approval of the merger agreement, the plan of merger and the transactions contemplated by the merger agreement, including the merger, be submitted to a vote at an extraordinary general meeting of the shareholders of the Company with the recommendation of the board of directors that the shareholders of the Company authorize and approve by way of a special resolution the merger agreement, the plan of merger and the transactions contemplated by the merger agreement, including the merger. Based in part on the unanimous recommendation of the Special Committee, our board of directors (with Messrs. Longhua Piao, Syed Hisham bin Syed Wazir and Xizhong Xu, the directors related to the Rollover Shareholders or the management of the Company, abstaining) determined that it is fair to and in the best interests of the Company and its unaffiliated security holders, and declared it advisable, to enter into the merger agreement, and authorized and approved the execution, delivery and performance of the merger agreement, the plan of merger and the other documents referred to in the merger agreement and the consummation of the transactions contemplated by the merger agreement, including the merger. ACCORDINGLY, OUR BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE FOR THE PROPOSAL TO AUTHORIZE AND APPROVE THE MERGER AGREEMENT, THE PLAN OF MERGER AND THE TRANSACTIONS CONTEMPLATED BY THE MERGER AGREEMENT, INCLUDING THE MERGER, AND FOR THE PROPOSAL TO ADJOURN THE EXTRAORDINARY GENERAL MEETING IN ORDER TO ALLOW THE COMPANY TO SOLICIT ADDITIONAL PROXIES IN THE EVENT THAT THERE ARE INSUFFICIENT PROXIES RECEIVED TO PASS THE SPECIAL RESOLUTION DURING THE EXTRAORDINARY GENERAL MEETING.

Each member of the Buyer Group is making the statements included in this paragraph solely for the purpose of complying with the requirements of Rule 13e-3 and related rules under the Exchange Act. The views of each of the members of the Buyer Group as to the fairness of the merger are not intended to be and should not be construed as a recommendation to any shareholder of the Company as to how that shareholder should vote on the proposal to authorize and approve the merger agreement, the plan of merger and the transactions contemplated by the merger agreement, including the merger.

The Company and the Buyer Group estimate that the total amount of funds necessary to complete the merger and the related transactions is approximately $70.5 million (assuming no exercise of dissenter rights by shareholders of the Company), which is expected to be provided through a combination of (a) an equity commitment of up to $22.5 million pursuant to an equity commitment letter from General Transactions and (b) a commitment from the Rollover Shareholders to roll over 150,000,000 Shares, with an aggregate value of $48.0 million, pursuant to the rollover agreement. See "Special Factors—Financing" beginning on page 65 for more information regarding the financing of the merger.

Concurrently with the execution of the merger agreement, HDS, WSP OCTG and JM OCTG entered into an equity commitment letter which was assigned by HDS, WSP OCTG and JM OCTG to General Transactions, Parent and Merger Sub, respectively, on March 19, 2014, pursuant to which General Transactions has committed, concurrently with the closing of the merger, that it would purchase, or cause the purchase of, equity interests of Parent for an aggregate amount up to $22.5 million and cause Parent, upon receipt of such amount, to purchase equity interests of Merger Sub for an aggregate amount equal to such commitment. The equity commitment is conditioned upon (a) the satisfaction or waiver at the closing of each of the conditions to Parent's and Merger Sub's obligations to consummate the transactions contemplated by the merger agreement and (b) the contemporaneous consummation of the closing.

Concurrently with the execution of the merger agreement, HDS entered into a limited guarantee in favor of the Company, which was amended and assigned by HDS to General Transactions on March 19, 2014 under which General Transactions agreed to guarantee the due and punctual observance and performance as and when due and subject to the conditions and limitations set forth therein and in the merger agreement or (a) Parent's obligation to pay a reverse termination fee to the Company under the merger agreement and (b) Parent's and Merger Sub's funding of the merger consideration under the merger agreement, in each case, subject to a cap of $1.0 million.

Share Ownership of the Company's Directors and Executive Officers and Voting Commitments (Page 105)

As of the share record date, Mr. Piao, the chairman of the board of directors and chief executive officer of the Company, beneficially owned approximately 50.9% of the total outstanding Shares. As of the share record date, UMW beneficially owned approximately 22.5% of the total outstanding Shares. Mr. Badrul Feisal bin Abdul Rahim, our director, is an executive director of UMW Holdings Berhad. Please see "Security Ownership of Certain Beneficial Owners and Management of the Company" beginning on page 105 for additional information regarding the ownership of Shares by the other directors and executive officers of the Company.

Pursuant to the voting agreements executed by the Rollover Shareholders, each of the Rollover Shareholders has agreed, among other things, (i) to vote, or cause to be voted, all of the Shares that it owns for the authorization and approval of the merger agreement and the transactions contemplated by the merger agreement, (ii) to vote against any other acquisition proposal, agreement or action made in opposition to the authorization and approval of the merger agreement or in competition or inconsistent with the merger and the other transactions contemplated by the merger agreement or that is intended or could reasonably be expected to materially impede, interfere with, delay, postpone, discourage or adversely affect the merger or any of the other transactions contemplated by the merger agreement, and (iii) not to initiate, solicit, propose, encourage or knowingly facilitate, including by providing information, any inquiries, proposals or offers with respect to, or the making or completion of, any acquisition proposals or offers that would reasonably be expected to lead to an acquisition proposal.

In connection with the merger, the Special Committee received an opinion from its financial advisor, Houlihan Lokey (China) Limited ("Houlihan Lokey"), dated February 21, 2013, as to the fairness, from a financial point of view and as of such date, of the per Share merger consideration to be received by holders of Shares and the per ADS merger consideration to be received by holders of ADSs (in each case other than Parent, Merger Sub, the Rollover Shareholders and their respective

affiliates). For purposes of the opinion, "Rollover Shareholders" refers to any shareholders of the Company, including Mr. Piao, EMH and UMW, that enter into a rollover agreement and voting agreement in connection with the merger. The full text of Houlihan Lokey's written opinion, dated February 21, 2013, which describes the procedures followed, assumptions made, qualifications and limitations on the review undertaken and other matters considered by Houlihan Lokey in preparing its opinion, is attached as Annex B to this Proxy Statement and is incorporated herein by reference.

Houlihan Lokey's opinion was furnished for the use of the Special Committee (in its capacity as such) in connection with its evaluation of the merger consideration from a financial point of view and did not address any other aspect or implication of the merger. The summary of Houlihan Lokey's opinion in this Proxy Statement is qualified in its entirety by reference to the full text of its written opinion. The opinion did not address the relative merits of the merger as compared to any alternative business strategies or transactions that might be available for the Company or any other party, nor did it address the underlying business decision of the Special Committee, the board of directors, the Company, its security holders or any other party or entity to proceed with or effect the merger or any terms or aspects of any rollover, voting or other agreements to be entered into in connection with the merger, any potential financing for the merger or the likelihood of consummation of such financing. Houlihan Lokey's opinion should not be construed as creating any fiduciary duty on Houlihan Lokey's part to any party or entity. Houlihan Lokey's opinion was not intended to be, and does not constitute, a recommendation to the Special Committee, the board of directors, any security holder or any other party or entity as to how to act or vote with respect to any matter relating to the merger or otherwise. Please see "Special Factors—Opinion of the Special Committee's Financial Advisor" beginning on page 52 for additional information.

Interests of the Company's Executive Officers and Directors in the Merger (Page 67)

In considering the recommendations of the board of directors, the Company's shareholders should be aware that certain of the Company's directors and executive officers have interests in the transaction that are different from, and/or in addition to, the interests of the Company's shareholders generally. These interests include, among others:

The Special Committee and our board of directors were aware of potential conflicts of interest and considered them, among other matters, in reaching their decisions and recommendations with respect to the merger agreement and related matters. Please see "Special Factors—Interests of Certain Persons in the Merger" beginning on page 67 for additional information.

From the date of the merger agreement until the earlier to occur of the effective time of the merger or the termination of the merger agreement, the Company (including any of its subsidiaries or its or their respective directors, officers or representatives) may not (i) solicit, initiate or induce the making, submission or announcement of, or knowingly encourage, facilitate or assist, any acquisition proposal; (ii) furnish to any person (other than Parent, Merger Sub or any designees of Parent or Merger Sub) any non-public information relating to the Company or any of its subsidiaries, or afford to any person (other than Parent, Merger Sub or any designees of Parent or Merger Sub) access to the business, properties, assets, books, records or other non-public information, or to any personnel, of the Company or any of its subsidiaries, in any such case with the intent to induce the making, submission or announcement of, or the intent to encourage, facilitate or assist, any acquisition proposal or any inquiries or the making of any proposal that would reasonably be expected to lead to any acquisition proposal; (iii) participate or engage in discussions or negotiations with any person with respect to any acquisition proposal; (iv) approve, endorse or recommend any acquisition proposal; or (v) enter into any contract contemplating or otherwise relating to any acquisition transaction. Upon signing the merger agreement, the Company is required to instruct its representatives that are engaged in ongoing discussions with any persons (other than Parent, Merger Sub or any of their representatives) with respect to an acquisition proposal to cease any such discussions.

Notwithstanding the foregoing, (i) if the Company receives an unsolicited acquisition proposal, the Special Committee may contact such persons making such acquisition proposal to clarify and understand the terms and conditions thereof in order to assess whether such acquisition proposal is reasonably expected to lead to a superior proposal; (ii) if the Company receives an unsolicited bona fide, written acquisition proposal that the Special Committee determines in good faith either constitutes or is reasonably expected to lead to a superior proposal, the Special Committee may participate or engage in discussions or negotiations with any persons making such acquisition proposal if it determines in good faith that failure to take such action would reasonably be expected to be inconsistent with its fiduciary duties, and/or (iii) if the Company receives an unsolicited bona fide, written acquisition proposal the Special Committee determines in good faith either constitutes or is reasonably expected to lead to a superior proposal, the Special Committee may furnish, pursuant to a confidentiality agreement, to such persons making such acquisition proposal, any non-public information relating to the Company or any of its subsidiaries, or afford to any such persons access to the business, properties, assets, books, records or other non-public information, or to any personnel, of the Company or any of its subsidiaries, if the Special Committee determines in good faith that failure to take such action would reasonably be expected to be inconsistent with its fiduciary duties. Notwithstanding the foregoing, the Company will not provide any commercially sensitive non-public information to any competitor in connection with the foregoing, except in a manner consistent with the Company's past practice in dealing with the disclosure of such information in the context of considering acquisition proposals.

Please see "The Merger Agreement and Plan of Merger—No Solicitation of Acquisition Proposals" for more information, including the definitions of "acquisition proposal" and "superior proposals" under the merger agreement.

The merger agreement may be terminated at any time prior to the effective time of the merger:

The exchange of Shares or ADSs for cash pursuant to the merger or through the exercise of dissenter rights will be a taxable transaction for U.S. federal income tax purposes and may also be a taxable transaction under applicable state, local and other tax laws. Please see "Material U.S. Federal Income Tax Considerations" beginning on page 107 for additional information. The tax consequences of the merger or the exercise of dissenter rights to you will depend upon your personal circumstances. You should consult your tax advisors for a full understanding of the U.S. federal, state, local, non-U.S. and other tax consequences of the merger to you.

The Company does not believe that it should be considered a resident enterprise under the PRC Enterprise Income Tax Law (the "EIT Law") or that the gain recognized on the receipt of cash for our Shares or ADSs should be subject to PRC tax to holders of such Shares and ADSs that are not PRC residents. If, however, the PRC tax authorities were to determine that the Company should be considered a resident enterprise or that the receipt of cash for our Shares or ADSs should otherwise be subject to PRC tax, then gain recognized on the receipt of cash for our Shares or ADSs pursuant to the merger or through the exercise of dissenter rights by our shareholders or ADS holders who are not

PRC residents could be treated as PRC-sourced income that would be subject to PRC income tax at a rate of 20% in the case of individuals or 10% in the case of corporations (subject to applicable treaty relief). You should consult with your own tax advisor for a full understanding of the tax consequences of the merger or the exercise of dissenter rights to you, including any PRC tax consequences. Please see "Material PRC Income Tax Considerations" beginning on page 110 for additional information.

The Cayman Islands currently have no form of income, corporate or capital gains tax and no estate duty, inheritance tax or gift tax. No taxes, fees or charges will be 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 the merger or the receipt of cash for our Shares and ADSs under the terms of the merger agreement. This is subject to the qualification that (a) Cayman Islands stamp duty may be payable if any transaction documents are brought to or executed or produced before a court in the Cayman Islands, and (b) registration fees will be payable to the Registrar of Companies to register the plan of merger. Please see "Material Cayman Islands Tax Considerations" beginning on page 111 for additional information.

The Company does not believe that any material federal or state regulatory approvals, filings or notices are required in connection with the merger other than the approvals, filings or notices required under the federal securities laws and the filing of the plan of merger (and supporting documentation as specified in the Cayman Islands Companies Law) with the Cayman Islands Registrar of Companies and, in the event the merger becomes effective, a copy of the certificate of merger being given to the shareholders and creditors of the Company and Merger Sub as at the time of the filing of the plan of merger and notice of merger published in the Cayman Islands Gazette.

Upon completion of the merger, the Company would cease to be a publicly traded company, and the Company expects to account for the merger at historical cost.

The consummation of the merger is subject to the satisfaction or waiver by mutual agreement of Parent and the Company (subject to the approval of the Special Committee) of the following conditions:

The obligations of Parent and Merger Sub to consummate the merger are also subject to the satisfaction, or waiver by Parent, of the following conditions:

The closing price of the ADSs on the NYSE on December 12, 2011, the last trading date immediately prior to the Company's announcement on December 13, 2011 that it had received a going private proposal, was $2.00 per ADS. The merger consideration of $3.20 per ADS to be paid in the merger represents a premium of approximately 60.0% over that closing price.

QUESTIONS AND ANSWERS ABOUT THE EXTRAORDINARY GENERAL MEETING AND THE MERGER

The following questions and answers address briefly some questions you may have regarding the extraordinary general meeting and the merger. These questions and answers may not address all questions that may be important to you as a shareholder of the Company. Please refer to the more detailed information contained elsewhere in this proxy statement, the annexes to this proxy statement and the documents referred to or incorporated by reference in this proxy statement.

Events leading to the execution of the merger agreement described in this Background of the Merger occurred in China and Hong Kong. As a result, China Standard Time is used for all dates and times given.

Our board of directors and senior management periodically review the Company's long-term strategic plans with the goal of enhancing shareholder value. As part of this ongoing process, our board of directors and senior management, from time to time, have considered potential strategic alternatives that may be available to the Company. In addition, from time to time since the Company became a public company, Mr. Piao, our largest shareholder, chairman of our board of directors and our chief executive officer, has been approached by certain institutions regarding the possibility of providing debt or equity financing to the Company. During these discussions, Mr. Piao gradually became interested in exploring the possibility of making an offer to acquire the Shares not already beneficially owned by him.

On September 9, 2011, Mr. Piao and Mr. Xizhong Xu ("Mr. Xu"), our assistant general manager and a director, held preliminary discussions with UMW, the Company's second largest shareholder, and certain other significant shareholders of the Company to explore the feasibility of a possible going private transaction with respect to the Company and the financing for such a transaction. During the discussions at that time, however, no agreement, arrangement or understanding was reached with any of these parties.

Also in early Septermber 2011, Mr. Piao and Mr. Xu reached out to their business contact Mr. Zhiwen Zhou ("Mr. Zhou"), a consultant and a partner at Wuxi Ziguang Yangming Investment Management Firm ("Wuxi Ziguang"), a local investment management firm in Wuxi, China, to help identify potential investors.

On September 28, 2011, after an introduction by Mr. Zhou, Mr. Piao and Mr. Xu met with Mr. Jubao Xie ("Mr. Xie"), the sole director and controlling shareholder of HDS, and Mr. Zhou, at Wuxi International Hotel to explore the possibility of HDS acquiring the Shares not beneficially owned by Mr. Piao in a going private transaction. Wuxi Ziguang has also acted as a financial advisor to HDS's PRC affiliate.

On October 12, 2011, Mr. Piao and Mr. Xu met with representatives of UMW and another shareholder of the Company in Shanghai to further discuss a potential going private transaction. In particular, the parties explored each shareholder's interest in rolling over its Shares into the post-merger entity as a surviving shareholder. No decision was made at that time.

On October 18, 2011, DLA Piper UK, LLP ("DLA Piper"), then engaged as HDS's legal advisor for the potential going private transaction of the Company, submitted a legal due diligence request list to Mr. Xu. No confidential, non-public information was provided by the Company in response to such request.

On November 19, 2011, Mr. Piao and Mr. Xu met with representatives of UMW in Beijing to further discuss UMW's potential interest in rolling over its Shares in the potential going-private transaction. While UMW did not give a definitive response at the time, UMW expressed interest in participating in further discussions involving the potential transaction.

On November 28, 2011, HDS submitted a preliminary, non-binding proposal (the "Proposal Letter") to our board of directors proposing to undertake a going private transaction with respect to the Company by acquiring all of the Shares held by the public shareholders for cash consideration of $0.30 per Share (or $3.00 per ADS (as adjusted for the ADS ratio change that occurred on February 15, 2012)). In the Proposal Letter, HDS stated, among other things, that it had had preliminary and informal communications with EMH, and certain other significant shareholders of the Company and that HDS believed these shareholders would be interested in pursuing a potential

transaction whereby (i) HDS would acquire Shares held by the public for cash and (ii) EMH and such other significant shareholders would exchange their Shares for shares of the acquirer, a special purpose vehicle to be formed by HDS for the sole purpose of the transaction. In the Proposal Letter, HDS also indicated that it expected to fund the transaction from its own capital.

On December 10, 2011, the board of directors of the Company held a meeting in Hong Kong to discuss, among other things, the Proposal Letter. During the meeting, representatives of Kirkland & Ellis, the Company's U.S. legal counsel, discussed with the board of directors its duties under applicable law in connection with the Proposal Letter and the possibility of establishing a special committee of independent and disinterested directors to independently evaluate the proposal contained in the Proposal Letter and the terms of the transaction contemplated thereby. Thereafter, each of Mr. Piao, Mr. Badrul Feisal bin Abdul Rahim (representing Mr. Syed Hisham bin Syed Wazir, our vice chairman, at the meeting), a representative of UMW, and Mr. Xu, recused themselves from the remainder of the meeting. At this time, UMW had not yet agreed to become a member of the Buyer Group, but continue to contemplate the possibility that it might later agree to roll over its Shares and become a member of the Buyer Group.

Thereafter, the remainder of the board of directors continued the meeting, and Kirkland & Ellis gave a presentation to the board of directors with respect to certain key aspects of going private transactions. After the presentation and a thorough discussion, the board of directors determined that it was advisable and in the best interests of the Company and its shareholders to establish the Special Committee, consisting of independent and disinterested directors including Mr. Dennis Zhu, Mr. Paul Weidong Wang and Mr. Michael Muhan Liu, to facilitate the directors' consideration of the proposal described in the Proposal Letter and the development and pursuit of any alternative offers for the Company. In connection therewith, the board of directors approved written resolutions authorizing the Special Committee to, among other things: (a) establish, monitor and direct the process and procedures related to the review and evaluation of the potential transaction and any alternative transaction, including the authority to determine not to proceed with any such process, procedures, review or evaluation; (b) respond to any communications, inquiries or proposals regarding the potential transaction or any alternative transaction; (c) review, evaluate and negotiate the terms and conditions of the potential transaction or any alternative transaction; (d) solicit expressions of interest or other proposals for alternative transactions; (e) recommend to the board of directors and the Company whether the potential transaction or any alternative transaction was advisable and was fair to, and in the best interests of, the Company and its shareholders; (f) recommend rejection or approval of the potential transaction or any alternative transaction to the board of directors; (g) take such actions as the Special Committee may deem to be necessary or appropriate in connection with anti-takeover provisions, including actions with respect to the adoption of a shareholder rights plan; (h) retain legal, financial and other advisors; and (i) take such other actions as the Special Committee may deem to be necessary or appropriate for the Special Committee to discharge its duties.

Later that day, the Special Committee held its organizational meeting in Hong Kong with representatives of Kirkland & Ellis. During the meeting, the Special Committee elected Mr. Dennis Zhu as chairman of the Special Committee and approved the retention of Kirkland & Ellis and Conyers Dill & Pearman (Cayman) Limited as U.S. and Cayman Islands legal counsel, respectively. The Special Committee also discussed with Kirkland & Ellis, among other things, a process for selecting and engaging a financial advisor to assist the Special Committee. The Special Committee authorized Kirkland & Ellis to contact potential financial advisors so that the Special Committee could consider their qualifications, advisory experience and matters related to a potential engagement. Representatives of Kirkland & Ellis also highlighted to the Special Committee that they should substantively engage with HDS only if the Special Committee determined to do so following its review, with the assistance of legal and financial advisors, of the proposal described in the Proposal Letter.

Also later that day, Mr. Piao confirmed to DLA Piper, and DLA Piper subsequently confirmed to Kirkland & Ellis, that Mr. Piao intended to roll over his Shares in the transaction with HDS, that he

was not interested in giving up control of the Company or selling any of his Shares and that he did not have the intention to otherwise participate in any other alternative transaction. At this time, UMW had not yet confirmed to HDS or the Company whether it intended to participate in the proposed transaction as a rollover shareholder. DLA Piper also communicated to Kirkland & Ellis that the merger consideration would be fully funded with cash available to HDS and that the merger agreement would not contain any requirement that HDS obtain third-party debt financing.

On December 13, 2011, the Company issued a press release announcing its receipt of the Proposal Letter and the formation of the Special Committee, and included the press release and the Proposal Letter as exhibits to its Current Report on Form 6-K furnished by the Company to the Securities and Exchange Commission on the same date.

During the period between December 14, 2011 and December 16, 2011, the Special Committee held telephonic interviews with four financial advisory firms to discuss their qualifications and related matters with respect to potentially acting as the Special Committee's financial advisor.

On December 16, 2011, the Special Committee held a telephonic meeting with representatives of Kirkland & Ellis to discuss, among other things, the independence, experience, qualifications and reputation of each of the four financial advisory firms it had interviewed. The Special Committee also discussed with Kirkland & Ellis whether, as a practical matter, there was any merit in seeking alternative proposals from third parties given Mr. Piao's indication that he was not interested in giving up control of the Company or selling any of his Shares and that he did not intend to otherwise participate in any other alternative transaction and the fact that Mr. Piao's beneficial ownership of approximately 50.9% of the total outstanding Shares (as of December 15, 2011) gives him the ability to veto any other transaction by voting against it. Representatives of Kirkland & Ellis recommended that the Special Committee confirm with Mr. Piao his stated intention not to sell his Shares or otherwise participate in another transaction given that the Special Committee's consideration of whether to seek alternative buyers would require Mr. Piao's willingness to sell his Shares and/or participate in such transaction.

On December 23, 2011, the Special Committee held a telephonic meeting with representatives of Kirkland & Ellis to discuss, among other things, the selection of a financial advisor.

On December 28, 2011, after final deliberation on the experience, qualifications and reputation of each of the four potential financial advisors it had interviewed, the Special Committee decided to engage Houlihan Lokey (China) Limited ("Houlihan Lokey") as its financial advisor. Among the reasons for Houlihan Lokey's selection were its extensive experience representing special committees in going private transactions, its strong reputation, its significant experience dealing with China-based companies, the absence of any existing material relationships between Houlihan Lokey with the Company or the Buyer Group and its ability to interact in both English and Chinese. Houlihan Lokey subsequently was engaged as the Special Committee's financial advisor.

On February 7, 2012, the Company provided to Houlihan Lokey certain financial projections for the fiscal years ending December 31, 2012 through December 31, 2017. See "Special Factors—Certain Financial Projections" for additional information. The Company's management subsequently discussed with Houlihan Lokey, among other topics, such projections and the Company's financial and operational condition, competition in the industry, strategic plans for the Company's business and their views on the risks and uncertainties associated with achieving such projections.

On February 27, 2012, the Special Committee held a telephonic meeting which was attended by representatives of Kirkland & Ellis and Houlihan Lokey. At this meeting, Houlihan Lokey updated the Special Committee on its discussions with the Company's management, certain considerations with respect to HDS's proposal and potential next steps as well as the Company's ADS trading history and other market data and certain financial considerations with respect to the proposal based on projections prepared by the Company's management and publicly available information, including

implied multiples for the Company based both on the Company's then current ADS closing price and the proposed purchase price reflected in the Proposal Letter as compared to implied multiples for selected companies and selected precedent transactions and implied premiums paid in selected precedent transactions. The implied latest 12 months and calendar years 2012 and 2013 revenue multiples for the Company were 1.31x, 1.02x and 0.89x, respectively (based on the Company's then current ADS closing price as of February 24, 2012), and 1.34x, 1.04x and 0.91x, respectively (based on the proposed purchase price reflected in the Proposal Letter). These multiples were compared with implied low, mean, median and high revenue multiples derived from selected publicly traded companies that manufacture pipes and related products for the oil and gas industry of 0.36x, 1.22x, 1.13x and 2.46x, respectively, for the latest 12 months for which information was publicly available, 0.22x, 0.97x, 0.94x and 2.18x, respectively, for calendar year 2012 and 0.44x, 0.98x, 0.85x and 2.01x, respectively, for calendar year 2013. The Company's implied latest 12 months revenue multiple based on the proposed purchase price reflected in the Proposal Letter of 1.34x also was compared with implied low, mean, median and high revenue multiples derived from the purchase prices paid in selected transactions involving manufacturers of tubular and non-tubular goods used in the energy sector of 0.45x, 1.38x, 1.45x and 2.93x, respectively, for the latest 12 months prior to announcement of the transaction. Also reviewed were implied premiums paid in selected going private transactions involving U.S.-listed Chinese companies based on the target company's closing stock price during various periods relative to the offer price in the relevant transaction, which indicated overall low and high mean premiums of approximately (-21.8%) and 42.2% and median premiums of approximately (-16.4%) and 30.6%, respectively. The Special Committee discussed, among other things, the challenges facing the Company with respect to the rapidly increasing cost of raw materials, depressed sale prices in China, the Company's significant bank debt and increased interest expense. It was noted that the purchase price of $0.30 per Share (or $3.00 per ADS) proposed by HDS represented a 50% premium for the holders of Shares and ADSs over the trading price of an ADS on December 12, 2011 (the last trading day prior to announcement of the receipt of the Proposal Letter). After full discussion, the Special Committee resolved to enter into discussions with HDS and the other members of the Buyer Group and requested that its legal and financial advisors discuss with HDS and DLA Piper a potential increase in HDS's proposed purchase price.

Representatives of Kirkland & Ellis then gave a presentation on the terms and provisions of a draft merger agreement prepared by Kirkland & Ellis that was distributed to the Special Committee in advance. Following the presentation, the Special Committee and its advisors discussed the importance of, among other things, limited closing conditions, obtaining assurances from HDS as to its ability to fund the merger consideration and either obtaining specific performance (including the right to require HDS to fund WSP OCTG up to the full amount of the merger consideration) or a meaningful reverse termination fee as a remedy for WSP OCTG or JM OCTG failing to abide by its obligations under the merger agreement. The Special Committee and its legal and financial advisors also discussed again Mr. Piao's earlier indication that he was not interested in giving up control of the Company or selling any of his Shares and that he did not intend to otherwise participate in an alternative transaction to the going private transaction proposed by HDS, whether UMW was part of the Buyer Group and the relative benefits and risks of conducting an active market check and/or conditioning any transaction with the Buyer Group on a majority vote of public minority shareholders not affiliated with the Buyer Group (a "majority-of-minority" voting condition). Following the discussion, the Special Committee asked its advisors to explore further with Mr. Piao whether there was any likely scenario available under which he would sell his Shares in or otherwise participate in an alternative transaction and to continue to determine whether UMW was part of the Buyer Group. The Special Committee decided to wait until it had more information on Mr. Piao's intentions before determining whether to contact third parties. The Special Committee then authorized Kirkland & Ellis to distribute a draft merger agreement to the Buyer Group for comment, which would include, among other things, a "go-shop" provision that would permit the Company to approach other potential buyers for a specified period after the execution of the merger agreement and a "majority-of-minority" voting condition.

On February 29, 2012, a representative of Kirkland & Ellis contacted a representative of DLA Piper to notify them that the Special Committee had authorized Kirkland & Ellis to engage with the Buyer Group in merger discussions by providing a draft merger agreement to the Buyer Group for consideration. Kirkland & Ellis indicated that the draft merger agreement would contain, among other things, a "go-shop" provision and a "majority-of-minority" voting condition. DLA Piper expressed concern on behalf of the Buyer Group with these two provisions, and Kirkland & Ellis then explored with DLA Piper whether HDS would be willing to increase its proposed price in the event the Special Committee removed these two provisions. The Kirkland & Ellis representative indicated that the Special Committee would consider the terms of any transaction in totality, which would include price, and that in any event HDS would need to demonstrate that it had sufficient financial resources to fund the merger consideration. Thereafter, Kirkland & Ellis provided an initial draft of the merger agreement to DLA Piper.

On March 13, 2012, in accordance with the Special Committee's directives, representatives of Houlihan Lokey attended a telephonic meeting with Mr. Piao during which Mr. Piao again indicated, among other things, that he was not interested in giving up control of the Company or selling Shares in the Company and that he did not intend to otherwise participate in an alternative transaction.

On March 20, 2012, the Special Committee held a telephonic meeting attended by representatives of Kirkland & Ellis and Houlihan Lokey. After a brief reminder by Kirkland & Ellis of the directors' duties under applicable law, Houlihan Lokey updated the Special Committee as to the discussions with Mr. Piao on March 13, 2012. The Special Committee then engaged in a discussion with its advisors regarding whether to conduct a third-party solicitation process given Mr. Piao's indication that he was not interested in giving up control of the Company or selling any of his Shares and that he did not intend to otherwise participate in an alternative transaction. After deliberating at length, the Special Committee concluded that, given Mr. Piao's beneficial ownership of approximately 50.9% of the total outstanding Shares (as of March 19, 2012) and his ability to veto any other transaction by voting against it, contacting third parties to assess their interest in an alternative transaction would be futile and would not be in the best interests of the Company or its shareholders. In reaching this conclusion, the Special Committee considered that such a process, among other things, would potentially risk the withdrawal of HDS's proposal or an adverse change in such proposal, and given both the premium implied by HDS's proposed price and the expected future financial performance of the Company, would be unlikely to produce a competing offer on terms more favorable to the Company or its unaffiliated security holders than those contained in the Proposal Letter. The Special Committee then instructed its advisors to continue negotiations with HDS and to focus on obtaining the best terms available.

On April 1, 2012, DLA Piper provided preliminary comments to the merger agreement, noting that the comments were subject to further input by the Buyer Group.

On April 9, 2012, the Special Committee held a telephonic meeting that was attended by representatives of Kirkland & Ellis and Houlihan Lokey. During the meeting, Kirkland & Ellis summarized the comments from DLA Piper to the merger agreement, including their deletion of (i) a reverse termination fee that would serve as liquidated damages in the event WSP OCTG or JM OCTG failed to perform its obligations under the merger agreement, (ii) the Company termination fee as the sole and exclusive remedy in the event the board of directors were to exercise its right to change its recommendation and (iii) the provision stating that WSP OCTG or JM OCTG could not claim a breach of the merger agreement by the Company if any Rollover Shareholder (including Mr. Piao) caused the breach or if such breach relates to a matter of which any Rollover Shareholder (including Mr. Piao) had knowledge. After discussion, the Special Committee requested that Kirkland & Ellis convey to the Buyer Group that the Company was unable to agree to these proposed changes. The Special Committee also directed Kirkland & Ellis and Houlihan Lokey to continue to seek evidence from HDS that it had sufficient resources to satisfy WSP OCTG's and JM OCTG's obligations under the merger agreement.

On April 10, 2012, representatives of Kirkland & Ellis delivered the Special Committee's feedback on the merger agreement to DLA Piper during a telephonic meeting. During the meeting, Kirkland & Ellis conveyed to DLA Piper the importance from the Special Committee's perspective that the obligations under the merger agreement be guaranteed by a creditworthy entity.

On April 14, 2012, in accordance with the Special Committee's directives, representatives of Houlihan Lokey held a telephonic meeting with Mr. Xie of HDS, Mr. Zhou, a representative of the financial advisor of HDS's PRC affiliate, authorized by Mr. Xie to negotiate on his behalf in connection with the proposed transaction, and representatives of DLA Piper, regarding, among other things, the extent and nature of HDS's operations.

On April 18, 2012, in accordance with the Special Committee's directives, representatives of Houlihan Lokey held a telephonic meeting with Mr. Zhou and representatives of DLA Piper to discuss the proposed transaction and HDS's proposed price of $0.30 per Share (or $3.00 per ADS). On behalf of the Special Committee, Houlihan Lokey informed HDS that the Special Committee expected HDS to increase its proposed price.

On April 24, 2012, a representative of DLA Piper contacted a representative of Kirkland & Ellis in order to communicate, among other things, that UMW was in discussions with HDS regarding rolling over its shares and that HDS would be willing to increase its proposed price to an amount between $0.315 per Share (or $3.15 per ADS) and $0.32 per Share (or $3.20 per ADS) if favorable terms on the definitive transaction documents could be reached. DLA Piper also stressed HDS's desire to minimize the overall transaction timing.

On April 25, 2012, the Special Committee held a telephonic meeting attended by representatives of Kirkland & Ellis, Conyers Dill & Pearman (Cayman) Limited and Houlihan Lokey. Kirkland & Ellis provided the Special Committee with an update regarding UMW's likelihood of rolling over its shares and HDS's willingness to increase its proposed price in the event acceptable terms were agreed upon by the parties. Following this update, Conyers Dill & Pearman (Cayman) Limited summarized the duties of the directors under applicable law in the context of the proposed transaction. Houlihan Lokey again updated the Special Committee as to certain financial considerations with respect to the proposed transaction, including the Company's ADS trading history and other market data and updated implied multiples based on projections prepared by the Company's management and publicly available information. The updated implied latest 12 months and calendar years 2012 and 2013 revenue multiples for the Company were 1.23x, 1.02x and 0.89x, respectively (based on the Company's then current ADS closing price as of April 24, 2012), and 1.29x, 1.07x and 0.93x, respectively (based on the increased proposed purchase price). These multiples were compared with updated implied low, mean, median and high revenue multiples derived from the selected publicly traded companies previously reviewed with the Special Committee of 0.28x, 1.14x, 1.20x and 2.14x, respectively, for the latest 12 months for which information was publicly available, 0.25x, 0.91x, 0.93x and 1.89x, respectively, for calendar year 2012 and 0.24x, 0.81x, 0.84x and 1.73x, respectively, for calendar year 2013. The Company's updated implied latest 12 months revenue multiple based on the increased proposed purchase price of 1.29x also was compared with implied low, mean, median and high revenue multiples derived from the purchase prices paid in selected transactions involving manufacturers of tubular and non-tubular goods used in the energy sector of 0.45x, 1.34x, 1.33x and 2.93x, respectively, for the the latest 12 months prior to announcement of the transaction. Also reviewed were updated implied premiums paid in selected going private transactions involving U.S.-listed Chinese companies based on the target company's closing stock prices during various periods relative to the offer price in the relevant transaction, which indicated overall low and high mean premiums of approximately (-15.4%) and 52.7% and median premiums of approximately (-12.2%) and 33.8%, respectively, as compared to the overall low and high premiums implied based on the increased proposed purchase price relative to the Company's closing ADS price during various periods of approximately (-64.1%) to 60.0%. The Special Committee again discussed, among other things, the challenges facing the Company with respect to the cost of raw materials, low sale prices in China and the Company's debt-related interest

expense had increased, that the Company's share price had continued to decline and that the Company recently had failed to meet certain financial covenants under its existing loan agreements. It was noted that an increased purchase price of up to $0.32 per Share (or $3.20 per ADS) proposed by HDS represented a 173.5% premium for the holders of Shares and ADSs over the price of an ADS on April 24, 2012. Following full discussion, the Special Committee concluded, among other things, that reaching a definitive agreement with the Buyer Group on the current terms was in the best interests of the Company and its shareholders (other than the shareholders affiliated with the Buyer Group) and authorized Kirkland & Ellis to accept the increased offer price and agree to remove the "go-shop" provision and the "majority-of-minority" voting condition, neither of which was required by applicable law, in exchange for the increased offer price.

Later that evening, Kirkland & Ellis sent a revised draft of the merger agreement to DLA Piper.

On May 8, 2012, DLA Piper sent initial drafts of a voting agreement, equity commitment letter from HDS and rollover agreement to Kirkland & Ellis.

On May 10, 2012, Kirkland & Ellis sent comments on the voting agreement to DLA Piper, which, among other things, added the Company as a third-party beneficiary of the Rollover Shareholders' obligation to vote in favor of the transaction.

On May 14, 2012, DLA Piper sent an initial draft of a limited guarantee to Kirkland & Ellis.

On May 16, 2012, Kirkland & Ellis sent comments to the equity commitment letter and the limited guarantee to DLA Piper which, among other things, added the Company as a third party beneficiary of the equity commitment letter from HDS and required HDS to guarantee a reverse termination fee in an amount equal to the aggregate merger consideration payable to holders of Shares and ADSs (excluding the Rollover Shareholders) in the event that WSP OCTG and JM OCTG failed to close the merger when obligated to do so.

On May 22, 2012, DLA Piper indicated to Kirkland & Ellis that HDS was prepared to offer $0.315 per Share (or $3.15 per ADS) and not $0.32 per Share (or $3.20 per ADS), as they previously had indicated they might be prepared to pay, and that they expected the reverse termination fee to be no more than $1.8 million.

On May 23, 2012, Kirkland & Ellis, on behalf of the Special Committee, sent a counterproposal to DLA Piper requesting that HDS agree to a $1.0 million company termination fee and pay $0.32 per Share (or $3.20 per ADS) in exchange for a $10 million reverse termination fee.

Later that day, DLA Piper confirmed to Kirkland & Ellis that HDS would be willing to pay $0.32 per Share (or $3.20 per ADS) and accept a Company termination fee of $1 million, but that it would not agree to a $10 million reverse termination fee.

In the evening on the same day, Kirkland & Ellis discussed with the Special Committee the open issues and confirmed that the Special Committee would be willing to accept the $1.8 million reverse termination fee in exchange for the increased purchase price of $0.32 per Share (or $3.20 per ADS) and a $1 million Company termination fee. The Special Committee reached this determination in light of the fact that the Company had the ability to, among other things, force specific performance and rely as a third-party beneficiary on the equity commitment letter with respect to the full amount of the equity commitment (which would be sufficient to fund the merger consideration).

On May 24, 2012, after further discussion on the termination fees and the purchase price, representatives of Kirkland & Ellis confirmed on behalf of the Special Committee, and DLA Piper confirmed on behalf of HDS, their agreement to the $0.32 per Share (or $3.20 per ADS) purchase price, the $1 million Company termination fee and the $1.8 million reverse termination fee.

Over the next several weeks, HDS continued to have discussions with the Rollover Shareholders about the transaction, including, without limitation, with respect to each Rollover Shareholder's rights and obligations as a shareholder of Parent after the completion of the merger.

On July 3, 2012, DLA Piper requested that Kirkland & Ellis circulate updated versions of the merger agreement and other transaction documents in anticipation of a meeting to be held between representatives of HDS and the Rollover Shareholders on July 5, 2012. The following day, Kirkland & Ellis sent to DLA Piper revised drafts of the merger agreement and the other transaction documents.

On July 5, 2012, Mr. Xie, on behalf of HDS, Mr. Xu, on behalf of Mr. Piao and EMH, and Mr. Badrul Feisal Abdul Rahim, on behalf UMW, held a meeting in Shanghai at which representatives of HDS and each of the Rollover Shareholders agreed to the form of the merger agreement and the other transaction documents to be entered into with the Company. At that meeting, HDS and the Rollover Shareholders did not finalize the terms of their arrangements regarding the respective rights and obligations of the shareholders of WSP OCTG following the closing of the merger. Later that day, DLA Piper communicated to Kirkland & Ellis that HDS and the Rollover Shareholders wanted to further discuss the terms of their arrangements regarding the respective rights and obligations of the shareholders of WSP OCTG following the closing of the Merger, and that HDS's willingness to execute the merger agreement with the Company was subject to reaching agreement in principle on such matters with the Rollover Shareholders.

On August 14, 2012, HDS terminated its relationship with DLA Piper upon the departure of the team of attorneys representing HDS from DLA Piper to Gunderson Dettmer Stough Villeneuve Franklin & Hachigian, LLP ("Gunderson Dettmer"). Gunderson Dettmer was thereafter retained as HDS's counsel. Over the next several months, UMW continued its discussion and negotiation with HDS and EMH on the terms of their arrangements regarding the respective rights and obligations of the shareholders of WSP OCTG following the closing of the merger.

On November 5, 2012 and January 4, 2013, Mr. Xu, Mr. Zhou, Gunderson Dettmer, Kirkland & Ellis and Houlihan Lokey held telephonic meetings to receive updates on the status of HDS's preparation of funds requisite to finance the merger. Following these telephonic meetings, Kirkland & Ellis and Houlihan Lokey relayed to the Special Committee the matters discussed.

In late November 2012, the Rollover Shareholders and HDS reached agreement in principle on their arrangements regarding the respective rights and obligations of the shareholders of WSP OCTG following the merger.

On February 1, 2013, Gunderson Dettmer informed Kirkland & Ellis that HDS would be prepared to sign the merger agreement and related transaction documents during the week of February 17, 2013, or the first week following the Chinese New Year holiday.

On February 21, 2013, the board of directors of the Company held a telephonic meeting with Kirkland & Ellis, Conyers Dill & Pearman (Cayman) Limited and Houlihan Lokey. Messrs. Longhua Piao, Syed Hisham bin Syed Wazir and Xizhong Xu, due to their interests in the business of the meeting, had chosen not to attend the meeting. Following a recap of previous fiduciary duty presentations by Conyers Dill & Pearman (Cayman) Limited, Kirkland & Ellis gave an update on the status of negotiations with the Buyer Group and summarized for the Special Committee the key terms and final resolution of all open items on the merger agreement and other transaction documents. Houlihan Lokey reviewed with the Special Committee its financial analysis of the merger consideration and delivered to the Special Committee an oral opinion, confirmed by delivery of a written opinion dated February 21, 2013, to the effect that, as of that date and based on and subject to the procedures followed, assumptions made, qualifications and limitations on the review undertaken and other matters considered by Houlihan Lokey in preparing its opinion, the per Share merger consideration to be received by holders of Shares and the per ADS merger consideration to be received by holders of ADSs (in each case other than WSP OCTG, JM OCTG, the Rollover Shareholders and their respective affiliates) was fair, from a financial point of view, to such holders.

Mr. Jing Lu then left the telephonic board meeting and Mr. Zhu commenced a telephonic meeting of the Special Committee. After considering the proposed terms of the merger agreement and the

other transaction agreements and taking into account the various factors described below under the heading titled "—Reasons for the Merger and Recommendation of the Special Committee and Our Board of Directors," the Special Committee unanimously determined that the merger agreement, plan of merger and the merger were fair (both substantively and procedurally) to and in the best interests of the Company and its unaffiliated security holders and declared it advisable for the Company to enter into the merger agreement and the other transaction agreements and recommended that the board of directors adopt a resolution approving and declaring the advisability of the merger agreement, the merger and the other transactions contemplated by the merger agreement and recommending that the shareholders of the Company authorize and approve the merger agreement, the plan of merger and the merger.

Thereafter, Mr. Jing Lu rejoined the telephonic meeting and Mr. Zhu resumed the meeting of the board of directors. The Special Committee presented its recommendation to the board of directors. After considering the proposed terms of the merger agreement and the other transaction agreements and taking into account the various factors described below under the heading titled "—Reasons for the Merger and Recommendation of the Special Committee and Our Board of Directors," the board of directors, with Messrs. Longhua Piao, Syed Hisham bin Syed Wazir and Xizhong Xu not present or participating, (a) determined that it is fair to and in the best interests of the Company and its unaffiliated security holders, and declared it advisable, to enter into the merger agreement, (b) authorized and approved the execution, delivery and performance of the merger agreement, the plan of merger and the other documents referred to in the merger agreement and the consummation of the transactions contemplated by the merger agreement, including the merger, and (c) resolved to direct that the authorization and approval of the merger agreement, the plan of merger and the transactions contemplated by the merger agreement, including the merger, be submitted to a vote at an extraordinary general meeting of the shareholders of the Company. See "—Reasons for the Merger and Recommendation of the Special Committee and Our Board of Directors" for a full description of the resolutions of the board of directors at this meeting.

In the afternoon on February 21, 2013, the Company, WSP OCTG and JM OCTG executed the merger agreement and the related transaction documents, and, late in the evening on the same day, the Company issued a press release announcing the execution of the merger agreement.

On August 8, 2013, Kirkland & Ellis discussed with the Special Committee the fact that due to the delay in the Company's filing of its Annual Report on Form 20-F for the year ended December 31, 2012, the Company would be unable to finalize the proxy statement and hold the shareholders' meeting to solicit shareholder approval, a condition precedent to the closing of the merger, prior to August 21, 2013, the termination date of the merger agreement. As a result, the Special Committee determined to consider extending the termination date of the merger agreement in order to allow the Company sufficient time to complete its proxy statement and obtain the requisite shareholder approval. On that day, Kirkland & Ellis also contacted Gunderson Dettmer to explore the possibility for the parties to amend the merger agreement to extend the termination date of the merger agreement. Gunderson Dettmer responded later that day that the Buyer Group was willing to consider an extension.

On August 14, 2013, immediately after the Company's quarterly board meeting, the members of the Special Committee convened a telephonic meeting, attended by Kirkland & Ellis, to discuss the extension of the termination date under the merger agreement. The Special Committee considered with Kirkland & Ellis the potential benefits and risks of the extension. During the discussions, the Special Committee noted that, based upon the update it received from the Company's management regarding the business of the Company during the quarterly board meeting and the Special Committee's knowledge of the Company's business and industry, the Special Committee (i) did not believe that there had been any material changes in the Company's operations, performance or in any of the projections or assumptions upon which Houlihan Lokey based its opinion since the delivery of the opinion on February 21, 2013, (ii) did not anticipate any such material changes to occur before a meeting of security holders is held to consider and approve the merger, (iii) believed that the factors

supporting the decision of the board of directors to approve the merger in February 2013 remained unchanged, and (iv) believed that the other premises and benefits of the merger remained valid. As such, the Special Committee determined that it was in the best interests of the Company and its unaffiliated security holders to extend the termination date to allow the Company sufficient time to obtain the requisite shareholder approval prior to the extended termination date. Moreover, the Special Committee noted that it had been granted by the board of directors the authority to cause the completion of the merger without further actions by the board of directors. Kirkland & Ellis informed the Special Committee that the Buyer Group had agreed to propose an extended termination date by later that day. After such discussions, the Special Committee unanimously approved the form of amendment to the merger agreement presented to it by Kirkland & Ellis prior to the meeting, subject to agreeing with the Buyer Group to a mutually acceptable extended termination date.

Later that day, the Special Committee reached an agreement with the Buyer Group to extend the termination date to December 31, 2013.

In the morning of August 15, 2013, the Special Committee approved the extended termination date of December 31, 2013. In the afternoon of August 15, 2013, the Company, WSP OCTG and JM OCTG executed the amendment to the merger agreement, and, late in the evening on the same day, the Company issued a press release announcing the execution of the amendment to the merger agreement.

On November 24, 2013, Mr. Piao informed representatives of Kirkland & Ellis that (i) HDS had indicated to Mr. Piao that it would be unable to proceed with the closing of the merger, and (ii) Mr. Piao had identified another potential investor, General Transactions, that was willing to assume the obligations of HDS under the merger agreement and related documents and complete the going private transaction of the Company on substantially similar terms as the terms agreed by HDS.

On November 26, 2013, representatives of Kirkland & Ellis updated the Special Committee about the recent developments. Kirkland & Ellis briefed the Special Committee about changes that would need to be made to the existing transaction documents in order to replace HDS with General Transactions, noting that HDS would need to assign its rights and obligations under the merger agreement to General Transactions, and that the termination date of the merger agreement would need to be further extended. The Special Committee then authorized Kirkland & Ellis to contact General Transactions to begin documenting the assignment and assumption.

On November 29, 2013, representatives of Kirkland & Ellis had a telephonic meeting with Baker & McKenzie LLP ("Baker & McKenzie"), General Transactions' legal advisor, during which Kirkland & Ellis and Baker & McKenzie discussed the documentation required to replace HDS with General Transactions. Both counsel on behalf of their respective clients agreed that each of HDS, WSP OCTG and JM OCTG would assign its rights and obligations under the merger agreement, the voting agreements, the rollover agreement, the equity commitment letter and the limited guarantee, in each case as applicable, to General Transactions, Parent and Merger Sub, respectively, and that General Transactions, Parent and Merger Sub would assume such rights and obligations, pursuant to certain assignment and assumption agreements with respect to these transaction documents to be entered into among the relevant parties.

Later that day, Kirkland & Ellis informed Gunderson Dettmer that General Transactions had agreed to assume the obligations of HDS under the merger agreement and the other transaction documents, and that in connection with such arrangements, HDS, WSP OCTG and JM OCTG would need to enter into certain assignment and assumption agreements.

On December 5, 2013, the Company, Mr. Piao and General Transactions entered into a confidentiality agreement with respect to the information received by General Transactions and its representatives in connection with the going private transaction.

On December 6, 2013, Kirkland & Ellis sent an initial draft of the amendment No. 2, assignment and assumption agreement to Baker & McKenzie. The draft contemplated an extension of the termination date under the merger agreement as well as an assignment of the merger agreement, the limited guarantee and the equity commitment letter to General Transactions or its subsidiaries.

On December 9, 2013, Kirkland & Ellis sent the draft amendment No. 2, assignment and assumption agreement to Gunderson Dettmer.

On December 10, 2013, Kirkland & Ellis sent an initial draft of the assignment and assumption agreement relating to the voting and rollover agreements to Baker & McKenzie and Gunderson Dettmer.

Later on December 10, 2013, Gunderson Dettmer provided to Kirkland & Ellis comments on the two draft agreements.

On December 11, 2013, Baker & McKenzie provided comments on the draft amendment No. 2, assignment and assumption agreement. In addition to the extension of the termination date, Baker & McKenzie requested, on behalf of General Transactions, that certain other amendments be made to the merger agreement, including (i) that the company disclosure letter delivered under the merger agreement be updated as of the date of the signing of the amendment No. 2, assignment and assumption agreement, (ii) that the Parent Termination Fee (as defined in the merger agreement) be reduced from US$1.8 million to US$1.0 million, (iii) that the Company obtain certain consents or waivers under certain loan agreements as a condition to the closing, and (iv) to delete the provision stating that Parent or Merger Sub could not claim a breach of the merger agreement by the Company if any Rollover Shareholder (including Mr. Piao) causes the breach or if such breach relates to a matter of which any Rollover Shareholder (including Mr. Piao) had knowledge.

On December 12, 2013, Kirkland & Ellis sent to Baker & McKenzie a revised draft of the amendment No. 2, assignment and assumption agreement. Later that day, Kirkland & Ellis and Baker & McKenzie held a telephonic meeting to discuss the comments on the draft agreement, during which Kirkland & Ellis communicated to Baker & McKenzie that a number of the requests made by General Transactions were not acceptable to the Special Committee. Following the discussion, Baker & McKenzie communicated the position of the Special Committee to General Transactions.

On December 17, 2013, Kirkland & Ellis sent to Baker & McKenzie an updated company disclosure letter.

On December 21, 2013, Baker & McKenzie sent to Kirkland & Ellis further comments to the amendment No. 2, assignment and assumption agreement.

On December 23, 2013, Kirkland & Ellis and Baker & McKenzie had a telephonic meeting to discuss the outstanding issues on the amendment No. 2, assignment and assumption agreement. During the meeting, Baker & McKenzie communicated to Kirkland & Ellis that General Transactions maintained its initial position on the key issues raised in its initial draft of the amendment No. 2, assignment and assumption agreement. In addition, General Transactions emphasized that they would require as a closing condition that the Company obtain a number of bank consents relating to the merger as well as bank waivers of past, current and anticipated defaults under each of the loan agreements to which a subsidiary of the Company is a party.

On December 25, 2013, Baker & McKenzie and the Rollover Shareholders each confirmed that they agreed to the revised form of the shareholders' agreement to be attached as an exhibit to the rollover agreement.

On December 26, 2013, Kirkland & Ellis sent to Baker & McKenzie an updated company disclosure letter, which included, among other things, the details of two transactions approved by the board of directors in December 2013 to dispose of two loss-making subsidiaries of the Company to certain unrelated third parties for nominal cash consideration.

On December 31, 2013, the termination date under the merger agreement, Kirkland & Ellis indicated to Gunderson Dettmer that the Special Committee was still working with the Buyer Group to finalize the terms of the amendment No. 2, assignment and assumption agreement and that an agreement would not be reached by the end of the day. Gunderson Dettmer confirmed that HDS would still be amenable to entering into the amendment No. 2, assignment and assumption agreement even if the parties are not ready to sign it by the termination date, and that HDS did not intend to terminate the merger agreement if no agreement had been reached by the termination date.

On the same day, Mr. Piao held a telephonic meeting with Sergey Alexandrovich Borovskiy of General Transactions to discuss the outstanding issues under the amendment No. 2, assignment and assumption agreement. Mr. Piao emphasized that, in the interest of promoting certainty of closing, his intention was not to add bank consents or waivers as closing conditions to the merger agreement.

On January 1, 2014, Kirkland & Ellis, on behalf of the Special Committee, circulated to Baker & McKenzie a revised draft of the amendment No. 2, assignment and assumption agreement. The revised draft (i) reflected the reduction of the Parent Termination Fee from US$1.8 million to US$1.0 million and the deletion of the provision stating that Parent or Merger Sub could not claim a breach of the merger agreement by the Company if any Rollover Shareholder (including Mr. Piao) causes the breach or if such breach relates to a matter of which any Rollover Shareholder (including Mr. Piao) had knowledge, but (ii) did not reflect the addition of bank consents and waivers as closing conditions, which had been requested by General Transactions. Kirkland & Ellis separately communicated to Baker & McKenzie that the Special Committee would not accept changes to the merger agreement that would impose additional conditions to closing.

Over the next several days, Kirkland & Ellis also worked with the Company to provide to Baker & McKenzie additional due diligence information, including as to the Company's compliance with certain covenants under its bank loans, in an attempt to address any concerns that General Transactions had regarding signing the amendment No. 2, assignment and assumption agreement without requiring additional closing conditions.

On January 2, 2014, the Company issued a press release disclosing that the parties to the going private transaction were in discussions about potentially extending the termination date under the merger agreement in order to give the parties more time to complete the transaction.

On January 13, 2014, Mr. Piao informed Kirkland & Ellis that members of the Buyer Group were planning to meet later in January to discuss the transaction.

On February 27, 2014, Baker & McKenzie indicated to Kirkland & Ellis that they had received instructions from General Transactions to complete the documentation for the revised transaction. Later that day, Kirkland & Ellis and Baker & McKenzie held a telephonic meeting during which they agreed to the documentation that had to be completed.

On March 5, 2014, Baker & McKenzie sent a revised draft of the amendment No. 2, assignment and assumption agreement reflecting the latest discussions among the members of the Buyer Group. Later that day, Kirkland & Ellis had a telephonic meeting with Baker & McKenzie to finalize the agreement. During this meeting, Kirkland & Ellis, on behalf of the Special Committee, proposed that the termination date be extended until June 30, 2014.

On March 7, 2014, Kirkland & Ellis distributed to Baker & McKenzie an updated copy of the disclosure letter of the Company.

On March 11, 2014, Baker & McKenzie confirmed that General Transactions would be willing to sign the amendment No. 2, assignment and assumption agreement on the terms discussed on the March 5, 2014 telephonic meeting, except that General Transactions would expect the termination date to be extended until May 31, 2014 instead of June 30, 2014. Later that day, Kirkland & Ellis circulated to Gunderson Dettmer and members of the Buyer Group a revised version of the amendment No. 2, assignment and assumption agreement reflecting the terms previously agreed.

On the evening on the same day, the Special Committee convened a telephonic meeting, attended by Kirkland & Ellis, to discuss the potential benefits and risks of entering into the amendment No. 2, assignment and assumption agreement. After considering the various factors described below under the heading titled "—Reasons for the Merger and Recommendation of the Special Committee and Our Board of Directors—Determination by the Special Committee to Approve the Amendment No. 2, Assignment and Assumption Agreement," the Special Committee determined that it was in the best interests of the Company and its unaffiliated securityholders to enter into the amendment No. 2, assignment and assumption agreement. Moreover, the Special Committee noted that it had been granted by the board of directors the authority to cause the completion of the merger without further actions by the board of directors.

Following the meeting of the Special Committee, Kirkland & Ellis informed Baker & McKenzie that the Special Committee had determined to approve the amendment No. 2, assignment and assumption agreement.

On March 19, 2014, the Company, Parent, Merger Sub, HDS and General Transactions executed the amendment No. 2, assumption and assignment agreement and related documents, and late in the evening on the same day, the Company issued a press release announcing the execution of the amendment No. 2, assignment and assumption agreement and related documents.

Reasons for the Merger and Recommendation of the Special Committee and Our Board of Directors

At a meeting on February 21, 2013, the Special Committee unanimously recommended that our board of directors adopt resolutions that:

At a meeting on February 21, 2013, our board of directors, after carefully considering all relevant factors, including the unanimous determination and recommendation of the Special Committee, approved and adopted the resolutions recommended by the Special Committee. Messrs. Longhua Piao, Syed Hisham bin Syed Wazir and Xizhong Xu, the directors related to the Rollover Shareholders or the management of the Company, abstained from voting because of the potential conflicts of interest.

In the course of reaching their respective determinations, the Special Committee and our board of directors considered the following substantive factors and potential benefits of the merger, each of which the Special Committee and our board of directors believed supported their respective decisions, but which are not listed in any relative order of importance:

In addition, the Special Committee and our board of directors believed that sufficient procedural safeguards were and are present to ensure that the merger is procedurally fair to our unaffiliated security holders and to permit the Special Committee and our board of directors to represent effectively the interests of such shareholders. These procedural safeguards, which are not listed in any relative order of importance, are discussed below:

The Special Committee and the board of directors also considered a variety of potentially negative factors discussed below concerning the merger agreement and the merger, which are not listed in any relative order of importance:

While the Special Committee and our board of directors recognize the potentially negative factors listed above for the Company to enter into the merger agreement and undertake the merger, they believe that the benefits to the Company and the Company's unaffiliated security holders of undertaking the going private transaction as discussed above outweigh these negative factors.

The foregoing discussion of information and factors considered by the Special Committee and our board of directors is not intended to be exhaustive, but includes a number of the material factors considered by the Special Committee and our board of directors. With respect to the factors summarized above, the Special Committee expressly adopted the financial analysis and opinion of its

financial advisor as its own. In view of the wide variety of factors considered by the Special Committee and our board of directors, neither the Special Committee nor our board of directors found it practicable to quantify or otherwise assign relative weights to the foregoing factors in reaching its conclusions. In addition, individual members of the Special Committee and our board of directors may have given different weights to different factors and may have viewed some factors more positively or negatively than others. The Special Committee recommended that our board of directors authorized and approve, and our board of directors authorized and approved, the merger agreement based upon the totality of the information presented to and considered by it.

Neither the Special Committee nor our board of directors considered the liquidation value of Company's assets because each considers the Company to be a viable going concern business where value is derived from cash flows generated from its continuing operations. In addition, the Special Committee and the board of directors believe that the value of the Company's assets that might be realized in the liquidation would be significantly less than its going concern value. Each of the Special Committee and the board of directors believes the analyses and additional factors it reviewed provided an indication of our going concern value. Neither the Special Committee nor our board of directors considered the Company's net book value, which is defined as total assets minus total liabilities, attributable to the shareholders of the Company, as a factor. The Special Committee and the board of directors believe that net book value is not a material indicator of the value of the Company as a going concern. The Company's net book value per Share as of December 31, 2012 was $0.75 (based on an aggregate net book value of $152,394 and 204,375,226 Shares outstanding). Net book value does not take into account the future prospects of the Company, market conditions, trends in the industry in which the Company competes or the business risks inherent in competing with larger companies in the industry.

Each of the Special Committee and the board of directors also considered the historical market prices of our ADSs as described under the caption "Market Price of the Company's ADSs, Dividends and Other Matters—Market Price of the ADSs" beginning on page 75. The Company is not aware of any firm offers made by any unaffiliated person, other than the filing persons, during the past two years for (i) the merger or consolidation of the Company with or into another company, or vice-versa, (ii) the sale or other transfer of all or any substantial part of the assets of the Company, or (iii) a purchase of the Company's securities that would enable the holder to exercise control of the Company; except with respect to (ii), the Company received and accepted an offer from Southern Tube LLC to purchase the production facilities held by Houston OCTG Group, Inc., our U.S. subsidiary, for a total consideration of $43.0 million, which transaction was completed on Novermber 9, 2012.

In reaching its determination that the merger agreement, the plan of merger and the transactions contemplated thereby, including the merger, are fair to and in the best interests of the Company and our unaffiliated security holders and its decision to authorize and approve the merger agreement and recommend the authorization and approval of the merger agreement by our shareholders, our board of directors, on behalf of the Company, considered the analysis and recommendation of the Special Committee and the factors examined by the Special Committee as described above in this section and adopted such recommendations and analysis. For the foregoing reasons, each of the Company and our board of directors believes that the merger agreement, the plan of merger and the transactions contemplated by the merger agreement, including the merger, are substantively and procedurally fair to and in the best interests of the Company and our unaffiliated security holders.

The Special Committee and the board of directors also considered the purposes and reasons for the Company to undertake the merger at this time. The Special Committee and the board of directors believe that the U.S. public equity markets do not provide an adequate platform for the Company to raise capital on reasonable terms nor do the U.S. public equity markets provide the existing shareholders with adequate levels of liquidity, and that the U.S. public equity markets impose regulatory and other market burdens, both in terms of the expense and the management resources

needed for the maintenance of a U.S. public company, that are not sufficiently justifiable in light of the benefits received by the Company as a U.S. public company. On the other hand, the status of a privately held company will give the Company greater operational flexibility and allow it to focus on its long-term growth and continuing improvements to its business absent the regulatory burden imposed upon public companies and the distractions caused by the public equity market's valuation of the Company's ADS. For the reasons above as well as the fact that the Special Committee and the board of directors believe that the merger is substantively and procedurally fair and in the best interest of the Company and our unaffiliated security holders, the Special Committee and the board of directors believe that it is appropriate for the Company to undertake the merger and the going private transaction at this time, so that it can achieve its goal of exiting the U.S. public equity market and become a privately held company.

Except as discussed in "Special Factors—Background of the Merger" and "Special Factors—Reasons for the Merger and Recommendation of the Special Committee and our Board of Directors," no director who is not an employee of the Company has retained an unaffiliated representative to act solely on behalf of unaffiliated security holders for purposes of negotiating the terms of the transaction and/or preparing a report concerning the fairness of the transaction.

Determination by the Special Committee to Authorize and Approve the Amendment No. 2, Assignment and Assumption Agreement

At a meeting on March 11, 2014, the Special Committee, after carefully considering all relevant factors, unanimously determined to approve the amendment No. 2, assignment and assumption agreement. In the course of reaching its determination, the Special Committee considered the following factors, among others:

After considering the factors set forth above and other relevant factors, the Special Committee determined that it was in the best interests of the Company and its unaffiliated securityholders to enter into the amendment No. 2, assignment and assumption agreement. The Special Committee noted that it had been granted by the board of directors the authority to cause the completion of the merger without further actions by the board of directors and that the merger agreement authorized and approved by the board of directors expressly contemplated that the Special Committee could authorize and approve amendments to the merger agreement.

The Special Committee considered whether to, and determined not to, request Houlihan Lokey to update its opinion prior to authorizing and approving the entry into the amendment No. 2, assignment and assumption agreement. As set forth above, the Special Committee believed that, since February 21, 2013, there had not been material changes or developments in the Company's results of operations, performance or condition (financial or otherwise), in the Company's position in the industries in which it and its subsidiaries operate, or in the economic conditions applicable to the markets and industries in which the Company and its subsidiaries operate, in each case, that would support the view that the value of the Company as of the date of the Special Committee's authorization and approval of the amendment No. 2, assignment and assumption agreement was greater than it was at the time when Houlihan Lokey delivered its opinion and, as a result, that there had not been any such material changes or developments that would contradict Houlihan Lokey's opinion. Consequently, the Special Committee determined not to request Houlihan Lokey to update its opinion.

Under the rules governing "going private" transactions, each member of the Buyer Group is deemed to be an affiliate of the Company, and therefore, required to express its belief as to the fairness of the merger to the Company's unaffiliated security holders. Each member of the Buyer Group is making the statements included in this section solely for the purpose of complying with the requirements of Rule 13e-3 and related rules under the Exchange Act. The views of the Buyer Group as to the fairness of the merger are not intended to be and should not be construed as a recommendation to any shareholder or ADS holder of the Company as to how that shareholder or holder of ADS should vote on the proposal to authorize and approve the merger agreement, the plan of merger and the transactions contemplated by the merger agreement, including the merger. The Buyer Group has interests in the merger that are different from, and/or in addition to, those of the

unaffiliated security holders of the Company by virtue of their continuing interests in the surviving company after the completion of the merger. Please see "Special Factors—Interests of Certain Persons in the Merger" beginning on page 67 for additional information. The Buyer Group believes the merger is fair for the Company's unaffiliated security holders on the basis of the factors described in "Special Factors—Reasons for the Merger and Recommendation of the Special Committee and Our Board of Directors" beginning on page 38 including the factors described below.

The Buyer Group believes that the interests of the Company's unaffiliated security holders were represented by the Special Committee, which negotiated the terms and conditions of the merger agreement with the assistance of its legal and financial advisors. The Buyer Group did not participate in the deliberations of the Special Committee regarding, and did not receive any advice from the Special Committee's advisors as to, the fairness of the merger to the Company's unaffiliated security holders. The Buyer Group attempted to negotiate a transaction that would be most favorable to it, and not to the Company's unaffiliated security holders and, accordingly, did not negotiate the merger agreement with a goal of obtaining terms that were substantively and procedurally fair to such holders. The members of the Buyer Group did not perform, or engage a financial advisor to perform, any independent valuation or other analysis to assist them in assessing the substantive and procedural fairness of the merger consideration to the Company's unaffiliated security holders.

Based on their knowledge and analysis of available information regarding the Company, as well as discussions with the Company's management regarding the Company and its business, and the factors considered by, and the conclusions of, the Special Committee and the Company's board of directors discussed in "Special Factors—Reasons for the Merger and Recommendation of the Special Committee and Our Board of Directors" beginning on page 38, the Buyer Group believes the merger is both substantively and procedurally fair to the Company's unaffiliated security holders based upon the following factors, which are not listed in any relative order of importance:

In addition to the foregoing, the Buyer Group considered the primary detriments of the merger to the Company's unaffiliated security holders, which include, without limitation, the following:

After having given these negative factors due consideration, the Buyer Group concluded that none of these factors, alone or in the aggregate, outweighs the other factors described above on which the Buyer Group based its determination that the merger is substantively and procedurally fair to the Company's unaffiliated security holders.

Although Cayman Islands law does not require, and the merger agreement is not subject to, approval by a majority of the unaffiliated security holders of the Company, the Buyer Group concluded that, as a result of the factors described above, including the procedural safeguards, the merger is procedurally and substantially fair to the unaffiliated security holders of the Company.

The Buyer Group did not consider net book value, which is an accounting concept based on historical costs, as a factor because it believes net book value is not a material indicator of the value of the Company as a going concern but rather is indicative of historical costs. The Company's net book value per Share as of December 31, 2012 was $0.75 (based on an aggregate net book value of $152,394 and 204,375,226 Shares outstanding). Net book value does not take into account the future prospects of the Company, market conditions, trends in the industry in which the Company competes or the business risks inherent in competing with larger companies in the industry.

The Buyer Group did not consider the Company's liquidation value because it considers the Company to be a viable, going concern and because the Company will continue to operate its business following the merger, and therefore did not consider liquidation value to be a relevant valuation method.

Except for the terms and conditions of the merger agreement (prior to the amendment No. 2, assignment and assumption agreement) that was previously entered into by and among the Company, WSP OCTG, JM OCTG and the agreements contemplated therein, the Buyer Group is not aware of, and thus did not consider in its fairness determination, any offers or proposals made by any unaffiliated third parties with respect to a merger or consolidation of the Company with or into another company, a sale of all or a substantial part of the Company's assets, or the purchase of the Company voting securities that would enable the holder to exercise control over the Company.

The Buyer Group did not receive any independent reports, opinions or appraisals from any outside party related to the proposed merger, and thus did not consider any such reports, opinions or appraisals in determining the substantive fairness of the proposed merger to the unaffiliated security holders.

The foregoing discussion of the information and factors considered and given weight by the Buyer Group in connection with its evaluation of the substantive and procedural fairness of the merger to the Company's unaffiliated security holders, is not intended to be exhaustive, but is believed by the Buyer Group to include all material factors considered by it. The Buyer Group did not find it practicable to and did not quantify or otherwise attach relative weights to the foregoing factors in reaching its conclusion as to the substantive and procedural fairness of the merger to the Company's unaffiliated security holders. Rather, the Buyer Group made the fairness determinations after considering all of the foregoing as a whole.

The foregoing discussion of the information and factors considered and given weight to by the Buyer Group in connection with its evaluation of the substantive and procedural fairness of the merger to the Company's unaffiliated security holders is consistent with the analysis undertaken by the Buyer Group, including General Transactions, prior to entering into the amendment No 2, assignment and assumption agreement, and is consistent with (and results in the same conclusion as) the analysis undertaken by the Buyer Group (including HDS) prior to entering into the initial merger agreement on February 21, 2013.

The Buyer Group believes that these factors provide a reasonable basis for its belief that the merger is both substantively and procedurally fair to the Company's unaffiliated security holders. This belief, however, is not intended to be and should not be construed as a recommendation by the Buyer Group to any shareholder or ADS holder of the Company to authorize and approve the merger agreement, the plan of merger and the transactions contemplated by the merger agreement, including the merger. The Buyer Group does not make any recommendations as to how such shareholders or ADS holders should vote with respect to the proposal to authorize and approve the merger agreement, the plan of merger and the transactions contemplated by the merger agreement, including the merger, at the extraordinary general meeting.

The Company does not generally make available to the public financial forecasts or internal projections as to future performance, revenues, earnings or financial condition. However, our management provided certain financial projections for the fiscal year ending December 31, 2012 through the fiscal year ending December 31, 2017 to HDS and General Transactions in connection with their due diligence of the Company. Please see "—Background of the Merger" beginning on page 26 for additional information. These financial projections also were provided to the Special Committee's financial advisor. These financial projections, which were based on our management's projection of our future financial performance as of the date provided under an optimistic scenario reflecting certain assumptions, were prepared by the Company's management for internal use and for use by the Special Committee's financial advisor in its financial analyses, and were not prepared with a view toward public disclosure or compliance with published guidelines of the SEC regarding forward-looking information

or the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of financial forecasts or U.S. generally accepted accounting principles ("U.S. GAAP").

In compiling the projections, the Company's management took into account historical performance, combined with estimates regarding key financial and operating data. Although the projections are presented with numerical specificity, they reflect, among other things, an optimistic scenario for the Company based on numerous assumptions and estimates as to future events made by our management, including the assumption that the Company and its subsidiaries would continue to obtain necessary financing or other capital resources for their operations notwithstanding certain covenant breaches under existing loan agreements and going concern uncertainties. However, this information is not fact and should not be relied upon as being necessarily predictive of actual future results. They involve significant risks, uncertainties and assumptions. In addition, factors such as industry performance, the market for our existing and new products, the competitive environment, expectations regarding future acquisitions or any other transaction and general business, economic, regulatory, market and financial conditions, all of which are difficult to predict and beyond the control of our management, may cause actual future results to differ materially from the results forecasted in these financial projections.

In addition, the projections do not take into account any circumstances or events occurring after the date when they were prepared. For instance, the projections do not give effect to the merger or any changes to our operations or strategy that may be implemented after the time the projections were prepared. Moreover, the Company historically has underperformed relative to its budget and its internal projections and, specifically, the actual performance of the Company for the fiscal year ended December 31, 2012 was materially less favorable to the Company than the performance set forth in the projections for the fiscal year ended December 31, 2012. Accordingly, there can be no assurance that the projections for future years will be realized or that actual results will not be significantly different from those contained in the projections. Neither of our current or former independent registered public accounting firms, MaloneBailey LLP ("MB") and Deloitte Touche Tohmatsu CPA Ltd. ("DTT"), respectively, has examined, compiled, or performed any procedures with respect to the financial projections or any amounts derived therefrom or built thereupon. Accordingly, neither MB nor DTT expresses any opinion or any other form of assurance on such information or its achievability. The report of MB and DTT accompanying our audited consolidated financial statements included in the Company's Annual Report on Form 20-F for the year ended December 31, 2012 incorporated by reference in this proxy statement refers exclusively to the Company's historical information and does not cover any other information in this proxy statement and should not be read to do so. The financial projections included in this proxy statement are included solely to give shareholders access to certain information that was made available to HDS and General Transactions and are not included for the purpose of influencing any shareholder to make any investment decision with respect to the merger, including whether or not to seek to exercise dissenter rights for his or her Shares.

The inclusion of the projections should not be regarded as an indication that the Company, the Buyer Group, the Special Committee, any of their respective advisors or anyone who received the projections then considered, or now considers, them as necessarily predictive of actual future events, and the projections should not be relied upon as such. None of the Company, the Buyer Group, the Special Committee or any of their respective advisors or any of their affiliates assumes any responsibility for the validity or completeness of the projections. None of the Company, the Buyer Group, the Special Committee or any of their respective advisors or any of their affiliates intends to, and each of them disclaims any obligation to, update, revise or correct the projections, except as required by law, if they are or become inaccurate (even in the short term).

The inclusion of the projections in this proxy statement should not be deemed an admission or representation by the Company, the Buyer Group or the Special Committee that they are viewed by the Company or the Buyer Group or the Special Committee as material information of the Company

and, in fact, the Company, the Buyer Group and the Special Committee view the projections as non-material because of the inherent risks and uncertainties associated with such long-range forecasts. The projections should be evaluated, if at all, in conjunction with the historical financial statements and other information regarding the Company contained in the Company's public filings with the SEC. In light of the foregoing factors and the uncertainties inherent in the projections, shareholders are cautioned not to place undue, if any, reliance on the projections included in this proxy statement.

The following table sets forth the financial projections provided by our management to the Special Committee's financial advisor and the Buyer Group:

	For the Year of

Houlihan Lokey has been engaged to act as financial advisor to the Special Committee in connection with the merger. In connection with this engagement, the Special Committee requested that Houlihan Lokey evaluate the fairness, from a financial point of view and as of the date of the opinion, of the per Share merger consideration to be received by holders of Shares and the per ADS merger consideration to be received by holders of ADSs (in each case other than WSP OCTG, JM OCTG, the Rollover Shareholders (including for the purposes of Houlihan Lokey's opinion, in addition to Mr. Piao, EMH and UMW, any other shareholders of the Company that may enter into rollover agreements or voting agreements following the date of the merger agreement) and their respective affiliates). On February 21, 2013, at a meeting of the Special Committee held to evaluate the merger, Houlihan Lokey rendered to the Special Committee an oral opinion, confirmed by delivery of a written opinion dated February 21, 2013, to the effect that, as of that date and based on and subject to the procedures followed, assumptions made, qualifications and limitations on the review undertaken and other matters considered by Houlihan Lokey in preparing its opinion, the per Share merger consideration to be received by holders of Shares and the per ADS merger consideration to be received by holders of ADSs (in each case other than WSP OCTG, JM OCTG, the Rollover Shareholders (including for the purposes of Houlihan Lokey's opinion, in addition to Mr. Piao, EMH and UMW, any other shareholders of the Company that may enter into rollover agreements or voting agreements following the date of the merger agreement) and their respective affiliates) was fair, from a financial point of view, to such holders.

The full text of Houlihan Lokey's written opinion, dated February 21, 2013, which describes the procedures followed, assumptions made, qualifications and limitations on the review undertaken and other matters considered by Houlihan Lokey in preparing its opinion, is attached as Annex B to this Proxy Statement and is incorporated herein by reference. Houlihan Lokey's opinion was furnished for the use of the Special Committee (in its capacity as such) in connection with its evaluation of the merger consideration from a financial point of view and did not address any other aspect or implication of the merger. The summary of Houlihan Lokey's opinion in this Proxy Statement is qualified in its entirety by reference to the full text of its written opinion. The opinion did not address the relative merits of the merger as compared to any alternative business strategies or transactions that might be available for the Company or any other party, nor did it address the underlying business decision of the Special Committee, the board of directors, the Company, its security holders or any other party or entity to proceed with or effect the merger or any terms or aspects of any rollover, voting or other agreements to be entered into in connection with the merger, any potential financing for the merger or the likelihood of consummation of such financing. Houlihan Lokey's opinion should not be construed as creating any fiduciary duty on Houlihan Lokey's part to any party or entity. Houlihan Lokey's opinion was not intended to be, and does not constitute, a recommendation to the Special Committee, the board of directors, any security holder or any other party or entity as to how to act or vote with respect to any matter relating to the merger or otherwise.

In connection with its opinion, Houlihan Lokey made such reviews, analyses and inquiries as it deemed necessary and appropriate under the circumstances. Among other things, Houlihan Lokey:

Houlihan Lokey relied upon and assumed, without independent verification, the accuracy and completeness of all data, material and other information furnished, or otherwise made available, to Houlihan Lokey, discussed with or reviewed by Houlihan Lokey, or publicly available, and did not assume any responsibility with respect to such data, material and other information. Houlihan Lokey was advised by the Company's management that the only long-term projections for the Company were those prepared and provided to Houlihan Lokey by such management in February 2012, that certain changes occurred in the Company's business and operations since February 2012 and that the actual performance of the Company for the fiscal year ended December 31, 2012 was materially less favorable than as reflected in such long-term projections. It was Houlihan Lokey's understanding that the Company and its subsidiaries were in breach of certain financial covenants under certain loan agreements and that the consolidated financial statements of the Company for the fiscal year ended December 31, 2011 included an explanatory paragraph indicating that there was a going concern uncertainty for the Company, which could adversely affect the ability of the Company to meet its ongoing financing needs and obtain third-party financing. Notwithstanding the foregoing, the Company's management advised Houlihan Lokey, and Houlihan Lokey assumed, at the Special Committee's direction, that the financial projections and other estimates (and adjustments thereto)

utilized in Houlihan Lokey's analyses were reasonably prepared in good faith on bases reflecting the best available estimates and judgments of such management as to the future financial results and condition of the Company under an optimistic scenario. Houlihan Lokey expressed no opinion with respect to such projections and estimates or the assumptions on which they are based.

Houlihan Lokey relied upon and assumed, without independent verification, that there had been no change in the business, assets, liabilities, financial condition, results of operations, cash flows or prospects of the Company since the respective dates of the most recent financial statements and other information, financial or otherwise, provided to Houlihan Lokey that would be material to its analyses or opinion, and that there was no information or any facts that would have made any of the information reviewed by Houlihan Lokey incomplete or misleading. In addition, Houlihan Lokey understood that financial projections for the Company were prepared by the Company's management in RMB. Houlihan utilized certain publicly available RMB to United States dollar exchange rates and assumed, with the Special Committee's consent, that such exchange rates were reasonable to utilize for purposes of its analyses. Houlihan Lokey expressed no view or opinion as to any currency or exchange rate fluctuations and assumed, with the Special Committee's consent, that any such fluctuations would not in any respect be material to its analyses or opinion. Houlihan Lokey also relied, at the Special Committee's direction, upon the assessments of the Company's management as to, among other things, (i) macroeconomic conditions and governmental and regulatory matters affecting the Company, (ii) the amount of restricted cash currently available for the Company's operations and the continued availability of such cash for its operations and (iii) cyclical and market trends and prospects for the oil and gas industry, including assumptions of the Company's management as to future oil, gas and related commodity prices, which are subject to significant volatility and which, if different than as assumed, could impact Houlihan Lokey's analyses or opinion. Houlihan Lokey assumed, with the Special Committee's consent, that there would be no developments with respect to any such matters that would affect its analyses or opinion. In addition, the Company's management advised Houlihan Lokey, and Houlihan Lokey assumed, at the Special Committee's direction, that each ADS represents, and is equivalent for purposes of Houlihan Lokey's analyses and opinion to, ten Shares.

Houlihan Lokey relied upon and assumed, without independent verification, that (a) the representations and warranties of all parties to the merger agreement and all other related documents and instruments were true and correct, (b) each party to the merger agreement and such other related documents and instruments would fully and timely perform all of the covenants and agreements required to be performed by such party, (c) all conditions to the consummation of the merger would be satisfied without waiver, and (d) the merger would be consummated in a timely manner in accordance with the terms described in the merger agreement and such other related documents and instruments, without any amendments or modifications. Houlihan Lokey also relied upon and assumed, without independent verification, that (i) the merger would be consummated in a manner that complied in all respects with all applicable international, federal and state statutes, rules and regulations, and (ii) all governmental, regulatory, and other consents and approvals necessary for the consummation of the merger would be obtained and no delay, limitations, restrictions or conditions would be imposed or amendments, modifications or waivers made that would have had an effect on the Company or the merger that would have been material to Houlihan Lokey's analyses or opinion. In addition, Houlihan Lokey relied upon and assumed, without independent verification, that the final executed merger agreement would not differ in any respect from the execution version of the merger agreement identified above.

Furthermore, in connection with its opinion, Houlihan Lokey was not requested to make, and did not make, any physical inspection or independent appraisal or evaluation of any of the assets, properties or liabilities (fixed, contingent, derivative, off-balance sheet or otherwise) of the Company or any other party or entity, nor was Houlihan Lokey provided with any such appraisal or evaluation. Houlihan Lokey did not estimate, and expressed no opinion regarding, the liquidation value of the

Company or any other entity or business. Houlihan Lokey did not undertake an independent analysis of any potential or actual litigation, regulatory action, possible unasserted claims or other contingent liabilities to which the Company was or may be a party or was or may be subject, or of any governmental investigation of any possible unasserted claims or other contingent liabilities to which the Company was or may be a party or was or may be subject.

Houlihan Lokey was not requested to, and did not, (a) initiate any discussions with, or solicit any indications of interest from, third parties with respect to the merger, the securities, assets, businesses or operations of the Company or any other party or entity, or any alternatives to the merger or (b) advise the Special Committee, the board of directors or any other party or entity with respect to alternatives to the merger. Houlihan Lokey's opinion was necessarily based on financial, economic, market and other conditions as in effect on, and the information made available to Houlihan Lokey as of, the date of its opinion. Houlihan Lokey did not undertake, and is under no obligation, to update, revise, reaffirm or withdraw its opinion, or otherwise comment on or consider events occurring or coming to Houlihan Lokey's attention after the date of its opinion. Houlihan Lokey's opinion did not purport to address potential developments in the credit, financial or stock markets, including, without limitation, the market for ADSs. Houlihan Lokey also did not express any opinion as to the price or range of prices at which ADSs would trade, or Shares may be transferable, at any time. In addition, Houlihan Lokey did not express any view as to, and did not assess or consider, foreign currency exchange risks associated with the merger or otherwise.

Houlihan Lokey's opinion related to the fairness, from a financial point of view, of the per Share consideration to be received in the merger pursuant to the merger agreement by holders of Shares and the per ADS consideration to be received in the merger pursuant to the merger agreement by holders of ADSs (in each case other than WSP OCTG, JM OCTG, the Rollover Shareholders (including for the purposes of Houlihan Lokey's opinion, in addition to Mr. Piao, EMH and UMW, any other shareholders of the Company that may enter into rollover agreements or voting agreements following the date of the merger agreement) and their respective affiliates), without regard to any rights, restrictions or limitations that may be attributable to Shares or ADSs, including, without limitation, conversion or other features, redemption fees or related expenses. Houlihan Lokey was not requested to opine as to, and did not express an opinion as to or otherwise address, among other things: (i) the underlying business decision of the Special Committee, the board of directors, the Company, its security holders or any other party or entity to proceed with or effect the merger, (ii) the terms of any arrangements, understandings, agreements or documents related to, or the form, structure or any other portion or aspect of, the merger (other than the consideration to the extent expressly specified in Houlihan Lokey's opinion) or otherwise, including, without limitation, any terms or aspects of any rollover, voting or other agreements to be entered into in connection with the merger, any potential financing for the merger or the likelihood of consummation thereof, (iii) the fairness of any portion or aspect of the merger to the holders of any class of securities, creditors or other constituencies of the Company, or to any other party or entity, except if and only to the extent expressly set forth in the last paragraph of Houlihan Lokey's opinion, (iv) the relative merits of the merger as compared to any alternative business strategies or transactions that might be available for the Company or any other party, (v) the fairness of any portion or aspect of the merger to any one class or group of the Company's or any other party's security holders or other constituents vis-à-vis any other class or group of the Company's or such other party's security holders or other constituents (including, without limitation, the allocation of any consideration amongst or within such classes or groups of security holders or other constituents), (vi) whether or not the Company, its security holders or any other party is receiving or paying reasonably equivalent value in the merger, (vii) the solvency, creditworthiness or fair value of the Company or any other participant in the merger, or any of their respective assets, under any applicable laws relating to bankruptcy, insolvency, fraudulent conveyance or similar matters, or (viii) the fairness, financial or otherwise, of the amount, nature or any other aspect of any compensation to or consideration payable to or received by any officers, directors or employees of any

party to the merger, any class of such persons or any other party, relative to the consideration or otherwise. Furthermore, no opinion, counsel or interpretation was intended in matters that required legal, regulatory, accounting, insurance, tax or other similar professional advice. Houlihan Lokey assumed that such opinions, counsel or interpretations had been or would be obtained from appropriate professional sources. Furthermore, Houlihan Lokey relied, with the Special Committee's consent, on the assessments by the Special Committee, the board of directors, the Company and their respective advisors as to all legal, regulatory, accounting, insurance and tax matters with respect to the Company, the merger or otherwise. The issuance of Houlihan Lokey's opinion was approved by a Houlihan Lokey committee authorized to approve opinions of this nature.

In preparing its opinion to the Special Committee, Houlihan Lokey performed a variety of analyses, including those described below. This summary is not a complete description of Houlihan Lokey's opinion or the financial analyses performed and factors considered by Houlihan Lokey in connection with its opinion. The preparation of a financial opinion is a complex analytical process involving various quantitative and qualitative judgments and determinations as to the most appropriate and relevant financial, comparative and other analytical methods employed and the adaptation and application of those methods to the particular facts and circumstances presented. Therefore, a financial opinion and its underlying analyses are not readily susceptible to summary description. Houlihan Lokey arrived at its ultimate opinion based on the results of all analyses undertaken by it and assessed as a whole and did not draw, in isolation, conclusions from or with regard to any one factor or method of analysis for purposes of its opinion. Accordingly, Houlihan Lokey believes that its analyses and the following summary must be considered as a whole and that selecting portions of its analyses, methodologies, and factors or focusing on information presented in tabular format, without considering all analyses, methodologies, and factors or the narrative description of the analyses, could create a misleading or incomplete view of the processes underlying Houlihan Lokey's analyses and opinion. Each analytical technique has inherent strengths and weaknesses, and the nature of the available information may further affect the value of particular techniques.

In performing its analyses, Houlihan Lokey considered industry performance, general business, economic, market and financial conditions and other matters as they existed on, and could be evaluated as of, the date of Houlihan Lokey's opinion, many of which are beyond the Company's control. Accordingly, the information may not reflect current or future market conditions. No company, business or transaction used in the analyses for comparative purposes is identical to the Company or the merger, and an evaluation of the results of those analyses is not entirely mathematical. Rather, the analyses involve complex considerations, judgments and assumptions concerning financial and operating characteristics and other factors that could affect the acquisition, public trading or other values of the companies, business segments or transactions analyzed. Houlihan Lokey believes that mathematical derivations (such as determining an average or median) of financial data are not by themselves meaningful and should be considered together with judgments and informed assumptions. The assumptions and estimates contained in Houlihan Lokey's analyses and the reference ranges resulting from any particular analysis are not necessarily indicative of actual values or predictive of future results or values, which may be significantly more or less favorable than those suggested by its analyses. In addition, analyses relating to the value of assets, businesses or securities do not purport to be appraisals or to reflect the prices at which assets, businesses or securities actually may be sold or acquired. Accordingly, the assumptions and estimates used in, and the results derived from, Houlihan Lokey's analyses are inherently subject to substantial uncertainty.

Houlihan Lokey's opinion and financial analyses were only one of many factors considered by the Special Committee in its evaluation of the merger consideration and should not be viewed as determinative of the views of the Special Committee or management with respect to the merger or the merger consideration. Houlihan Lokey was not requested to, and it did not, recommend the specific per Share consideration or per ADS consideration payable in the merger. The type and amount of

consideration payable in the merger was determined through negotiation by the Special Committee and Parent, and the decision to enter into the merger was solely that of the Special Committee and the board of directors.

The following is a summary of the material financial analyses reviewed by Houlihan Lokey with the Special Committee in connection with Houlihan Lokey's opinion. The order of analyses does not represent relative importance or weight given to those analyses by Houlihan Lokey. The financial analyses summarized below include information presented in tabular format. In order to fully understand Houlihan Lokey's financial analyses, the tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the financial analyses. Considering the data in the tables below without considering the full narrative description of the financial analyses, including the methodologies and assumptions underlying and the qualifications and evaluations affecting the analyses, could create a misleading or incomplete view of Houlihan Lokey's financial analyses.

Selected Companies Analysis. Houlihan Lokey performed a selected companies analysis of the Company by reviewing selected financial and stock market data of the Company and the seven selected publicly traded companies that manufacture pipes and related products for the oil and gas industry noted below. Houlihan Lokey reviewed enterprise values of the selected companies, calculated as equity market values based on closing stock prices on February 19, 2013 plus debt outstanding, preferred stock and minority interests less cash and cash equivalents, as a multiple of, to the extent publicly available, latest 12 months revenue and, for illustrative purposes, calendar year 2013 estimated revenue. The selected companies had overall enterprise values of approximately $179.5 million to $25.5 billion and overall low, mean, median and high observed revenue multiples of 0.26x, 1.37x, 1.03x and 2.60x, respectively, for the latest 12 months, and 0.22x, 1.01x, 0.88x and 2.21x, respectively, for calendar year 2013, as indicated below (data that was not publicly available has been marked as "NA"):

Based on Houlihan Lokey's professional judgment and after taking into account qualitative and quantitative factors with respect to the Company and the selected companies, including as to size, growth and profitability, Houlihan Lokey applied selected ranges of latest 12 months (as of September 30, 2012 for the Company and reflecting the most recent publicly available financial information of the selected companies as of February 19, 2013) and calendar year 2013 revenue multiples of 1.00x to 1.30x and 0.65x to 0.85x, respectively, derived from the selected companies to corresponding data of the Company. The Company's implied per ADS and per Share equity values derived from such selected revenue multiples were calculated as total enterprise value plus the Company's cash and cash equivalents, less minority interest and total debt, in each case as of September 30, 2012, divided by the number of fully diluted ADSs and ordinary shares of the Company. Financial data of the selected companies were based on publicly available research analysts' estimates, public filings and other publicly available information. The Company's financial data were based on the

Company's public filings and internal estimates of the Company's management. This analysis indicated the following approximate implied per ADS and per Share equity value reference ranges for the Company based on latest 12 months revenue, as compared to the per ADS merger consideration and per Share merger consideration, respectively:

Houlihan Lokey noted for the Special Committee that the Company provided financial projections in February 2012 that the Company's management advised Houlihan Lokey had not been updated and that the Company historically had underperformed relative to its budget and relative to such projections. Accordingly, as indicated above, Houlihan Lokey performed a selected companies analysis based on calendar year 2013 estimated revenue for illustrative purposes, which indicated approximate implied per ADS and per Share equity value reference ranges for the Company of $0.00 to $3.62 and $0.00 to $0.36, respectively, as compared to the U.S.$3.20 per ADS merger consideration and U.S.$0.32 per Share merger consideration, respectively.

Selected Transactions Analysis. Houlihan Lokey performed a selected transactions analysis of the Company in which Houlihan Lokey reviewed certain publicly available financial terms of the 22 selected transactions noted below, nine of which involved manufacturers of tubular goods used in the energy sector and 13 of which involved manufacturers of non-tubular goods used in the energy sector. Houlihan Lokey reviewed transactions values of the selected transactions, calculated as the implied enterprise value of the target company based on the announced transaction equity price plus debt outstanding, preferred stock and minority interests less cash and cash equivalents, as a multiple of, to the extent publicly available, such target companies' latest 12 months revenue. The selected transactions had overall transaction values of approximately $1.5 million to $21.9 billion and overall low, mean, median and high latest 12 months observed revenue multiples (excluding the Yalian Steel Corporation and Seaboard International, Inc. transactions as outliers) of 0.40x, 1.52x, 1.33x and 3.96x, respectively, as indicated below (data that was not publicly available has been marked as "NA"):

Based on Houlihan Lokey's professional judgment and after taking into account qualitative and quantitative factors with respect to the Company and the target companies involved in the selected transactions, including as to size and profitability, Houlihan Lokey applied a selected range of latest 12 months revenue multiples of 0.90x to 1.30x derived from the selected transactions to the Company's latest 12 months revenue as of September 30, 2012. The Company's implied per ADS and per Share equity values derived from such selected revenue multiples were calculated as total enterprise value plus the Company's cash and cash equivalents, less minority interest and total debt, in each case as of September 30, 2012, divided by the number of fully diluted ADSs and ordinary shares of the Company. Financial data of the selected transactions and the Company were based on publicly available information. This analysis indicated the following approximate implied per ADS and per Share equity value reference ranges for the Company, as compared to the per ADS and per Share merger consideration, respectively:

Illustrative Discounted Cash Flow Analysis. As described above, given that the projections prepared by the Company's management had not been updated since February 2012 and the Company historically had underperformed relative to its budget and relative to such projections, Houlihan Lokey performed a discounted cash flow analysis of the Company for illustrative purposes by calculating the estimated present value of the standalone unlevered, after-tax free cash flows that the Company was forecasted to generate during the fiscal years ending December 31, 2013 through December 31, 2017 based on internal estimates of the Company's management. The implied terminal value of the Company was derived by applying to the Company's terminal year unlevered free cash flows a selected range of perpetuity growth rates of 4.5% to 5.5% derived taking into consideration publicly available long-term projected growth and inflation rates for various markets relating to the Company's business and the overall economy. Present values (as of February 19, 2013) of cash flows and terminal values were calculated using a discount rate range of 13.5% to 15.5% derived based on a weighted average

cost of capital calculation (a measure of the weighted average expected return on a given company's equity and debt securities based on their relative proportions in such company's capital structure). The Company's implied per ADS and per Share equity values derived from such free cash flows were calculated as total enterprise value plus the Company's cash and cash equivalents, less minority interest and total debt, in each case as of September 30, 2012, divided by the number of fully diluted ADSs and ordinary shares of the Company. This analysis indicated approximate implied per ADS and per Share equity value reference ranges for the Company of $0.00 to $4.22 and $0.00 to $0.42, respectively, as compared to the U.S.$3.20 per ADS merger consideration and U.S.$0.32 per Share merger consideration, respectively.

Under the terms of Houlihan Lokey's engagement as the Special Committee's financial advisor, the Company agreed to pay Houlihan Lokey an aggregate fee of $1.05 million, portions of which were payable during the course of its engagement and upon delivery of Houlihan Lokey's opinion and $200,000 of which is payable contingent upon completion of the merger. In addition, the Company agreed to reimburse Houlihan Lokey for certain of its expenses, including fees and expenses of its legal counsel, and to indemnify Houlihan Lokey and related parties against liabilities, including liabilities under federal securities laws, arising out of or in connection with the services rendered and to be rendered by Houlihan Lokey under its engagement.

The Special Committee selected Houlihan Lokey to act as its financial advisor in connection with the merger based on Houlihan Lokey's reputation and experience. Houlihan Lokey is regularly engaged to provide financial advisory services in connection with mergers and acquisitions, financings and financial restructuring.

In the ordinary course of business, certain of Houlihan Lokey's employees and affiliates, as well as investment funds in which they may have financial interests or with which they may co-invest, may acquire, hold or sell, long or short positions, or trade, in debt, equity, and other securities and financial instruments (including loans and other obligations) of, or investments in, the Company, HDS, EMH, UMW or any other party that may be involved in the merger and their respective affiliates or any currency or commodity that may be involved in the merger.

The preliminary presentations provided by Houlihan Lokey to the Special Committee on February 27, 2012 and April 25, 2012 did not constitute an opinion of, or recommendation by, Houlihan Lokey with respect to a possible transaction or otherwise. The preliminary presentations included certain preliminary financial considerations for the Special Committee utilizing procedures that were generally similar to those contained in Houlihan Lokey's final financial presentation to the Special Committee on February 21, 2013 summarized above. Houlihan Lokey's final presentation on February 21, 2013 was provided in connection with its opinion to the Special Committee and superseded the prior presentations.

Houlihan Lokey and certain of its affiliates in the future may provide investment banking, financial advisory and other financial services to the Company, HDS, EMH, UMW, other participants in the merger and their respective affiliates, and one or more security holders or portfolio companies of such entities, for which Houlihan Lokey and such affiliates may receive compensation. In addition, Houlihan Lokey and certain of its affiliates and certain of its and their respective employees may have committed to invest in private equity or other investment funds managed or advised by HDS, EMH, UMW or other participants in the merger or certain of their respective affiliates or security holders, and in portfolio companies of such funds, and may have co-invested with such funds, HDS, EMH, UMW or other participants in the merger or certain of their respective affiliates or security holders, and may do so in the future. Furthermore, in connection with bankruptcies, restructurings, and similar matters, Houlihan Lokey and certain of its affiliates in the past may have acted, currently may be acting and in

the future may act as financial advisor to debtors, creditors, equity holders, trustees and other interested parties (including, without limitation, formal and informal committees or groups of creditors) that may have included or represented and may include or represent, directly or indirectly, or may be or have been adverse to, the Company, HDS, EMH, UMW, other participants in the merger and/or their respective affiliates, and/or one or more security holders or portfolio companies of such entities, for which advice and services Houlihan Lokey and such affiliates have received and may receive compensation.

Each member of the Buyer Group is required to express its, his or her reasons for the proposed merger to the Company's unaffiliated security holders. Each member of the Buyer Group is making the statements included in this section solely for the purpose of complying with the requirements of Rule 13e-3 and related rules under Exchange Act.

Purpose and Reasons of Parent, Merger Sub and General Transactions for the Merger

Parent, Merger Sub and General Transactions believe that if the Company is a privately held entity, the Company's management will have greater flexibility to focus on improving the Company's long-term profitability without the constraints caused by the public equity market's valuation of the Company and emphasis on short-term period-to-period performance. As a privately held entity, the Company will have greater flexibility to make decisions that might negatively affect short-term results but that could increase the Company's value over the long term. In contrast, as a publicly-traded entity, the Company currently faces pressure from public shareholders and investment analysts to make decisions that might produce improved short-term results, but which are not necessarily beneficial in the long term.

As a privately held entity, the Company will be relieved of many of the other expenses, burdens and constraints imposed on companies that are subject to the public reporting requirements under the federal securities laws of the United States, including the Exchange Act and Sarbanes-Oxley Act of 2002. The need for the management of the Company to be responsive to the concerns of unaffiliated security holders and to engage in dialogue with unaffiliated security holders can also at times distract management's time and attention from the effective operation and improvement of the business.

For Parent, Merger Sub and General Transactions, the purpose of undertaking the transaction at this time is to enable Parent, Merger Sub and General Transactions to acquire a significant equity interest in the Company and to, collectively with Mr. Piao and UMW, bear the rewards and risks of the ownership of the Company after the ADSs cease to be publicly traded, including any increases in value of the Company as a result of improvements to the Company's operations or acquisitions of other businesses.

Additionally, Parent, Merger Sub and General Transactions believe that the merger will provide a prompt and orderly transfer of ownership of the Company in a single step, without the necessity of financing separate purchases of the Company's Shares and ADSs in a tender offer and a second-step merger to acquire the Shares and ADSs not tendered into the tender offer, and without incurring any additional transaction costs associated with such activities.

For the reasons above, Parent, Merger Sub and General Transactions believe that it is appropriate for them to undertake the transaction at this time, so that they can achieve the goal of acquiring a significant equity interest in the Company and participating in the ownership and management of the Company as a private entity, which is not subject to the various expenses, burdens and constraint that a public company is subject to.

For the Rollover Shareholders, the purpose of undertaking the transaction at this time is to enable the Company to exit the U.S. public equity markets and to operate as a privately held entity. The Rollover Shareholders believe that in the Company's current state, the U.S. public equity markets do not provide an adequate platform for the Company to raise capital on reasonable terms nor do the U.S. public equity markets provide the existing shareholders with adequate levels of liquidity while imposing regulatory and other market burdens, both in terms of the expense and the management resources needed for the maintenance of a U.S. public company, that are not sufficiently justifiable in light of the benefits received as a U.S. public company.

The Rollover Shareholders also believe that the status of being a privately held entity will provide the Company with flexibility to pursue certain strategic alternatives that it would not be practicable to pursue as a public company, including the ability to pursue business initiatives without focusing on the short-term market reaction of the Company's public stockholders with respect to such initiatives or the collective risk tolerance of such public stockholders as it relates to such initiatives. As a result, the Rollover Shareholders believe that it is in the long-term best interest of the Company to operate as a privately held entity in order to allow greater operational flexibility, focus on its long-term growth and continue improvements to its business, absent the regulatory burden imposed upon public companies and the distractions caused by the public equity market's valuation of the Company's Shares. The conversations with Parent, Merger Sub and General Transactions offered the Rollover Shareholders viable strategic alternatives that would address the concerns mentioned above, and coincided with a particularly negative outlook for Chinese companies accessing the U.S. public equity markets.

The Rollover Shareholders also believe that the merger provides the unaffiliated security holders the opportunity to achieve significant liquidity at a substantial premium over the price of the Company's Shares prior to the announcement of the transaction. At the same time, the merger will allow the Rollover Shareholders to maintain their investment in the Company through their respective commitments to hold continuing equity interest in Parent.

For the reasons above, the Rollover Shareholders believe that it is appropriate for them to undertake the transaction at this time, so that they can achieve the goal of maintaining their equity interest in the Company as a private entity, which is not subject to the various expenses, burdens and constraint that a public company is subject to.

The Company's ADSs are currently listed on the NYSE under the symbol "WH." It is expected that, immediately following the completion of the merger, the Company will cease to be a publicly traded company and will instead become a privately held company owned directly by Parent and indirectly by General Transactions and the Rollover Shareholders. Following the completion of the merger, the ADSs will cease to be listed on the NYSE, and price quotations with respect to sales of the ADSs in the public market will no longer be available. In addition, registration of the ADSs and the underlying Shares under the Exchange Act may be terminated upon the Company's application to the SEC if the Shares are not listed on a national securities exchange and there are fewer than 300 record holders of the Shares. Ninety days after the filing of Form 15 in connection with the completion of the merger or such longer period as may be determined by the SEC, registration of the ADSs and the underlying Shares under the Exchange Act will be terminated. At such time, the Company will no longer be required to file periodic reports with the SEC or otherwise be subject to the United States federal securities laws, including the Sarbanes-Oxley Act, applicable to public companies, and our shareholders will no longer enjoy the rights or protections that the United States federal securities laws provide, including reporting obligations for directors, officers and principal securities holders of the Company.

Under the terms of the merger agreement, at the effective time of the merger, each of our outstanding ordinary shares, par value $0.0001 per share (each, a "Share" and collectively, the "Shares"), including Shares represented by American Depositary Shares, each representing ten Shares (the "ADSs"), issued and outstanding immediately prior to the effective time of the merger, other than (a) Shares owned by Parent, Merger Sub or the Company (as treasury Shares, if any), or by any direct or indirect wholly-owned subsidiary of Parent, Merger Sub or the Company, in each case, immediately prior to the effective time of the merger; (b) the Rollover Shares (as defined below); and (c) the Shares owned by shareholders who have validly exercised and have not effectively withdrawn or lost their dissenter rights under the Cayman Islands Companies Law (the "Dissenting Shares" and, together with the Shares referred to in clause (a) and the Rollover Shares, the "Excluded Shares"), will be cancelled and cease to exist in exchange for the right to receive $0.32 per Share and, for the avoidance of doubt, each issued and outstanding ADS will represent the right to surrender the ADS in exchange for $3.20 in cash per ADS without interest (less $0.05 per ADS cancellation fees payable by holders of ADSs pursuant to the deposit agreement, dated December 6, 2007, as amended on February 1, 2012, among the Company, JPMorgan Chase Bank, N.A., as depositary (the "ADS depositary") and all holders of ADSs issued thereunder (the "Deposit Agreement")), in each case, net of any applicable withholding taxes. The Excluded Shares other than Dissenting Shares will be cancelled for no consideration at the effective time of the merger. The Dissenting Shares will be cancelled for their fair value in accordance with the Cayman Islands Companies Law. Please see "Dissenter Rights" beginning on page 100 for additional information.

The Rollover Shareholders have entered into a rollover agreement with WSP OCTG and JM OCTG, which was amended and assigned by WSP OCTG and JM OCTG to Parent and Merger Sub respectively on March 19, 2014 (as amended and assigned, the "rollover agreement") pursuant to which they have agreed to contribute to Parent the Shares owned by them, representing approximately 73.4% of the outstanding Shares as of February 21, 2012 (the "Rollover Shares"), in exchange for certain equity interests in Parent at the same price per share of Parent as is paid by General Transactions at the closing of the merger, such that each of the Rollover Shareholders, following the closing, will own an equity interest in Parent corresponding to its percentage ownership in the Company prior to the effective time of the merger.

At the effective time of the merger, each outstanding ordinary share of Merger Sub will be converted into one fully-paid and non-assessable ordinary share of the surviving company. As a result, current shareholders of the Company, other than the Rollover Shareholders, will no longer have any equity interest in, or be shareholders of, the Company upon completion of the merger. As a result, the Company's shareholders, other than the Rollover Shareholders, will not have the opportunity to participate in the earnings and growth of the Company and they will not have the right to vote on corporate matters. Similarly, our current shareholders, other than the Rollover Shareholders, will not be exposed to the risk of loss in relation to their investment in the Company.

If the merger is completed, the current memorandum of association and articles of association of the Company will be replaced in its entirety by the memorandum of association and articles of association of Merger Sub, as in effect prior to the completion of the merger (except that, at the effective time of the merger, Article I of the articles of association of the surviving company will be amended to read as follows: "The name of the corporation is WSP Holdings Limited."). In addition, the directors of Merger Sub immediately prior to the effective time (identified below in "Annex D—Directors and Executive Officers of the Company and Each Entity in the Buyer Group") will become the directors of the surviving company and the officers of the Company will become the officers of the surviving company.

The primary benefits of the merger to the Company's unaffiliated security holders include, without limitation, the following:

The primary detriments of the merger to the Company's unaffiliated security holders include, without limitation, the following:

The table below sets out the indirect interest in the Company's net book value and net earnings for Mr. Piao, UMW and General Transactions before and immediately after the merger, based on the historical net book value of the Company as of December 31, 2012 and the net earnings of the Company for the fiscal year ended December 31, 2012. The indirect interest in the Company's net book value and net earnings for Mr. Piao, UMW and General Transactions after the merger also reflects a shareholding adjustment among Mr. Piao, UMW and General Transactions after the merger.

Following the completion of the merger, Parent will own 100% of the equity interest in the Company. The Buyer Group anticipates that the Company will continue to conduct its operations substantially as they are currently being conducted, except that it will cease to be a publicly traded company and will instead be a wholly-owned subsidiary of Parent.

Subsequent to the completion of the merger and the termination of registration of the Company's ADSs and underlying Shares under the Exchange Act, the Company will no longer be subject to the Exchange Act or NYSE compliance and reporting requirements and the related direct and indirect costs and expenses, and may experience positive effects on profitability as a result of the elimination of such costs and expenses.

Except as set forth in this proxy statement and transactions already under consideration by the Company, the Buyer Group does not have any current plans, proposals or negotiations that relate to or would result in any of the following:

The board of directors of the Company did not independently determine to initiate a process for the sale of the Company. The Special Committee was formed on December 10, 2011, in response to the receipt of the going private proposal letter from HDS on November 28, 2011. In light of Mr. Piao's indication that he was not interested in giving up control of the Company or in selling Shares and that he did not intend to otherwise participate in an alternative transaction and his ownership of

approximately 50.9% of the total outstanding Shares (as of March 19, 2014), the Special Committee determined that there was no viable alternative to the proposed sale of the Company to the Buyer Group and, in light thereof, no attempt was made to contact third parties that might otherwise have considered an acquisition of the Company. Since the Company's receipt of the proposal letter from HDS on November 28, 2011, as well as during the past three years, other than General Transactions' offer to enter into the amendment No. 2, assignment and assumption agreement, the Company has not received any actionable offer from any third party for (i) a merger or consolidation of the Company with another company, (ii) the sale or transfer of all or substantially all of the Company's assets or (iii) the purchase of all or a substantial portion of the Shares that would enable such person to exercise control of or significant influence over the Company. The Special Committee also took into account that, prior to the receipt of shareholder approval, among other things, the Company may terminate the merger agreement if the board of directors (acting through the Special Committee) determines in its good faith judgment that failure to do so would be inconsistent with its fiduciary duties, subject to the payment of a termination fee of $1.0 million according to the merger agreement. In this regard, the Special Committee recognized that it has flexibility under the merger agreement to respond to an alternative transaction proposed by a third party that is or is reasonably likely to result in a superior proposal, including the ability to provide information to and engage in discussions and negotiations with such party (and, if such proposal is a superior proposal, recommend such proposal to the Company's shareholders).

If the merger agreement is not authorized and approved by the shareholders or if the merger is not completed for any other reason, shareholders will not receive any payment for their Shares or ADSs in connection with the merger. Instead, the Company will remain a publicly traded company with certain members of the Buyer Group holding a majority of the outstanding Shares, the ADSs will continue to be listed and traded on the NYSE, provided that the Company continues to meet the NYSE's listing requirements, and the Company will remain subject to SEC reporting obligations. Therefore, the Company's shareholders will continue to be subject to similar risks and opportunities as they currently are with respect to their ownership of our Shares or ADSs. Accordingly, if the merger is not completed, there can be no assurance as to the effect of these risks and opportunities on the future value of your Shares or ADSs, including the risk that the market price of the ADSs may decline to the extent that the current market price reflects a market assumption that the merger will be completed.

Under specified circumstances, the Company may be required to pay Parent a termination fee of $1.0 million, or Parent may be required to pay the Company a termination fee of $1.0 million, in each case, as described under the caption "The Merger Agreement and Plan of Merger—Termination Fees" beginning on page 97.

If the merger is not completed, from time to time, the board of directors of the Company will evaluate and review, among other things, the business, operations, dividend policy and capitalization of the Company and make such changes as are deemed appropriate and continue to seek to identify strategic alternatives to enhance shareholder value. If the merger agreement is not authorized and approved by the shareholders or if the merger is not completed for any other reason, there can be no assurance that any other transaction acceptable to the Company will be offered, or that the business, prospects or results of operations of the Company will not be adversely impacted.

The Company and the Buyer Group estimate that the total amount of funds necessary to complete the merger and the related transactions, including for the payment of the merger consideration to the Company's unaffiliated security holders pursuant to the merger agreement and fees and expenses in connection with the merger, is approximately $70.5 million, assuming no exercise of dissenter rights by

shareholders of the Company. This amount is expected to be provided through a combination of (a) an equity commitment of up to $22.5 million pursuant to an equity commitment letter dated February 21, 2013 which was assigned by HDS to General Transactions pursuant to the amendment No. 2, assignment and assumption agreement, and (b) a commitment from the Rollover Shareholders to roll over 150,000,000 Shares, with an aggregate value of $48.0 million, pursuant to the rollover agreement. As of the date of this proxy statement, there are no alternative financing arrangements or plans in place to acquire the funds necessary for the merger and the related transactions.

Concurrently with the execution of the merger agreement, HDS, WSP OCTG and JM OCTG entered into an equity commitment letter which was assigned by HDS to General Transactions pursuant to the amendment No. 2, assignment and assumption agreement, under to which HDS has committed, concurrently with the closing of the merger, that it would purchase, or cause the purchase of, equity interests of Parent for an aggregate amount up to $22.5 million, and cause Parent, upon receipt of such amount, to purchase equity interests of Merger Sub for an aggregate amount equal to such commitment.

The equity commitment is conditioned upon (a) the execution and delivery of the merger agreement by the Company and (b) the satisfaction or waiver at the closing of the merger of each of the conditions to Parent's and Merger Sub's obligations to consummate the transactions contemplated by the merger agreement. The obligation of General Transactions to fund the commitment will automatically terminate upon the earliest to occur of (i) the valid termination of the merger agreement, (ii) the closing of the merger (subject to performance of the obligation of General Transactions to contribute the equity commitment), and (iii) the Company or any of its affiliates asserting a claim against General Transactions, Parent or Merger Sub, or certain of their related parties under the merger agreement or ancillary agreements, other than certain specified retained claims. The Company is an express third-party beneficiary of the equity commitment letter having the right to enforce the General Transactions obligation to fund the equity financing.

Concurrently with the execution of the merger agreement, HDS entered into a limited guarantee in favor of the Company which was assigned to General Transactions pursuant to the amendment No. 2, assignment and assumptions agreement, under which General Transactions agreed to guarantee the due and punctual observance and performance as and when due and subject to the conditions and limitations set forth therein and in the merger agreement, or (a) Parent's obligation to pay a reverse termination fee to the Company under the merger agreement and (b) Parent's and Merger Sub's funding of the merger consideration under the merger agreement, in each case, subject to a cap of $1.0 million. The limited guarantee will terminate on the earliest of (i) the effective time of the merger, (ii) the termination of the merger agreement in accordance with its terms in circumstances in which Parent would not be obligated to pay the reverse termination fee, and (iii) the 120th day after the termination of the merger agreement in circumstances in which a reverse termination fee is due and owing by Parent, unless the Company has commenced a legal proceeding against Parent or Merger Sub alleging a reverse termination fee is due and owning or against General Transactions alleging amounts payable by General Transactions pursuant to the terms of the limited guarantee.

restrain breaches or threatened breaches of the merger agreement by the other, and to specifically enforce the terms and provisions of the merger agreement and any other agreements or arrangements implementing the merger to prevent breaches or threatened breaches of, or to enforce compliance with, the covenants and obligations of the other under the merger agreement and the merger. This right includes the right of the Company to cause Parent and Merger Sub to fully enforce the equity commitment letter against General Transactions to the fullest extent permissible pursuant to applicable laws and to thereafter cause the merger to be consummated.

Subject to any equitable remedies the Company may be entitled to, our right to receive payment of a termination fee of $1.0 million from Parent (or General Transactions, if requested to pay by the Company under the limited guarantee), is our sole and exclusive remedy for any loss or damage suffered as a result of the failure of the merger to be consummated under certain circumstances or for a breach or failure to perform under the merger agreement or otherwise.

Subject to any equitable remedies Parent or Merger Sub may be entitled to, Parent's right to receive payment of a termination fee of $1.0 million from us, is the sole and exclusive remedy of Parent and Merger Sub against us for any loss or damage suffered as a result of the failure of the merger to be consummated under certain circumstances or for a breach or failure to perform under the merger agreement or otherwise.

The maximum aggregate liability of Parent and Merger Sub, on the one hand, and the Company, on the other hand, for monetary damages in connection with the merger agreement is limited to the termination fee payable by the Company or Parent (or General Transactions, if requested to pay by the Company), as the case may be.

In considering the recommendation of the Special Committee and our board of directors with respect to the merger, you should be aware that the Rollover Shareholders, including Mr. Piao, has interests in the merger that are different from, and/or in addition to, the interests of our shareholders generally. The Company's board of directors and Special Committee were aware of such interests and considered them, among other matters, in reaching their decisions to approve the merger agreement, the plan of merger and the transactions contemplated by the merger agreement, including the merger, and recommend that our shareholders vote in favor of the authorization and approval of the merger agreement, the plan of merger and the transactions contemplated by the merger agreement, including the merger.

Concurrently with the execution of the merger agreement, the Rollover Shareholders executed the rollover agreement pursuant to which they have agreed to contribute to Parent the Rollover Shares owned by them, representing approximately 73.4% of the outstanding Shares, in exchange for certain equity interest in Parent at the same price per share of Parent as is paid by General Transactions at the closing such that (i) EMH and Mr. Piao will hold in aggregate of approximately 50.9% of the outstanding interest in Parent, and (ii) UMW will hold approximately 22.5% of the outstanding interests in Parent.

Given the Company will become a privately-held company following the completion of the merger, the Rollover Shareholders' interests in the surviving company will be illiquid, with no public trading market for the surviving company's shares and no certainty of an opportunity to sell their beneficial interests in the surviving company at an attractive price, or that any dividends paid by the surviving company will be sufficient to recover their investment. Each of the Rollover Shareholders may also enjoy benefits from future earnings and growth of the surviving company.

As of the date of this proxy statement, our directors and executive officers as a group beneficially owned an aggregate of 164,748,000 Shares. See "Security Ownership of Certain Beneficial Owners and Management of the Company" beginning on page 105.

On December 10, 2011, our board of directors established the Special Committee to consider the proposal from HDS and to take any actions it deems appropriate to assess the fairness and viability of

such proposal. The Special Committee is composed of independent directors Messrs. Dennis D. Zhu (who serves as the Chairman), Weidong Wang and Michael Muhan Liu. All of such directors are free from any affiliation with the Buyer Group, and none of such directors is or was ever an employee of the Company or any of its subsidiaries or has any financial interest in the merger that is different from that of the unaffiliated security holders of the Company other than (a) receipt of board and Special Committee member compensation, which payment is not contingent upon the completion of the merger or the Special Committee's or our board of directors' recommendation of the merger, and (b) their indemnification and liability insurance rights under the merger agreement as described above, none of the members of the Special Committee has a financial interest in the merger or any of transactions contemplated thereby and none of them is related to any member of Buyer Group or the management of the Company. Our board of directors did not place any limitations on the authority of the Special Committee regarding its investigation and evaluation of the merger.

We compensate the members of the Special Committee in exchange for their service in such capacity in an aggregate amount of $10,000 per member, the payment of which is not contingent upon the completion of the merger or the Special Committee's or the board's recommendation of the merger.

After the completion of the merger, Mr. Piao expects to continue to serve as chairman of the board of directors of the surviving company and chief executive officer of the surviving company. It is anticipated that the executive officers of the Company will hold positions with the surviving company that are substantially similar to their current positions.

We have adopted an audit committee charter, which requires the audit committee of our board of directors to review and approve all related party transactions as defined in Item 404 of Regulation S-K on an ongoing basis. For a description of our related party transactions, please see "Item 7. Major Shareholders and Related Party Transactions" included in our Annual Report on Form 20-F for the fiscal year ended December 31, 2012, incorporated by reference into this proxy statement. Please see "Where You Can Find More Information" beginning on page 113 for a description of how to obtain a copy of our Annual Report.

Except for the arrangements in connection with the merger discussed elsewhere in this proxy statement, during the past two years (i) there were no negotiations, transactions or material contacts between the Company and its affiliates, on the one hand, and any member of the Buyer Group, on the other hand, concerning any merger, consolidation, acquisition, tender offer for or other acquisition of any class of the Company's securities; election of the Company's directors or sale or other transfer of a material amount of assets of the Company; (ii) the Company and its affiliates did not enter into any other transaction with an aggregate value exceeding 1% of our consolidated revenues with any member of the Buyer Group, and (iii) none of the Company's executive officers, directors or affiliates that is a natural person entered into any transaction during the past two years with an aggregate value (in respect of such transaction or series of similar transactions with that person) exceeding $60,000 with any member of the Buyer Group.

Fees and expenses incurred or to be incurred by the Company and the Buyer Group in connection with the merger are estimated at the date of this proxy statement to be as set forth in the table below. Such fees are subject to change pending completion of the merger:

These expenses will not reduce the merger consideration to be received by the shareholders of the Company. If the merger is completed, the party incurring any costs and expenses in connection with the merger and the merger agreement will be responsible for such costs and expenses, except as otherwise provided in the merger agreement.

Pursuant to the voting agreements executed by each of the Rollover Shareholders, each dated February 21, 2013 and further amended and assigned on March 19, 2014, each of the Rollover Shareholders has agreed (i) to vote, or cause to be voted, all of the Shares that it owns for the authorization and approval of the merger agreement and the transactions contemplated by the merger agreement, (ii) to vote against any other acquisition proposals which could reasonably be expected, to materially impede, interfere with, delay, postpone, discourage or adversely affect the merger or any of the other transactions contemplated by the merger agreement, and (iii) not to initiate, solicit, propose, encourage or knowingly facilitate, including by providing information, any inquiries, proposals or offers with respect to, or the making or completion of, any acquisition proposals or offers that would reasonably be expected to lead to an Acquisition Proposal.

As of share record date, we expect that the Rollover Shareholders as a group will beneficially own, in the aggregate, 150,000,000 Shares, which represents approximately 73.4% of the total outstanding Shares.

We are not aware of any lawsuit that challenges the merger, the merger agreement or any of the transactions contemplated thereby.

Upon completion of the merger, the Company would cease to be a publicly traded company, and the Company expects to account for the merger at historical cost.

in the event the merger becomes effective, a copy of the certificate of merger being given to the shareholders and creditors of the Company and Merger Sub as at the time of the filing of the plan of merger and notice of merger being published in the Cayman Islands Government Gazette.

On December 12, 2011, the last trading day immediately prior to the Company's announcement on December 13, 2011 that it had received a going private proposal, the reported closing price of our ADSs on the New York Stock Exchanges was $2.00 per ADS, adjusted to reflect the change in number of Shares represented by the ADS in February 2012. The merger consideration of $0.32 per Share and $3.20 per ADS in cash representing a premium of 49.2% over the Company's 30 trading day volume-weighted average closing price (adjusted to reflect the change in number of Shares represented by the ADS in February 2012) calculated using the market data quoted by the NYSE on December 12, 2011, the last trading day prior to the Company's announcement on December 13, 2011 that it had received a going private proposal. On , 2014, the most recent practicable date before the printing of this proxy statement, the high and low reported closing prices of our ADSs were $ and $ , respectively. You are urged to obtain a current market price quotation for your Shares in connection with voting your Shares.

We have not paid any dividend during the past two years. We are not required to pay dividends. Our shareholders or ADS holders also do not have contractual or other rights to require us to pay dividends. We do not expect to declare or pay any dividends prior to the merger, and under the terms of the merger agreement, are prohibited from doing so without Parent's prior written approval. We currently intend to retain all available funds and any future earnings for use in the operation and expansion of our business, and do not anticipate paying any cash dividends on our Shares, or indirectly on our ADSs, in the foreseeable future.

In addition, our board of directors has complete discretion on whether to pay dividends, subject to Parent's rights under the merger agreement. Even if our board of directors decides to pay dividends, the form, frequency and amount will be subject to the complete discretion of our board of directors, depending upon various factors, such as our future operations and earnings, available cash and distributable reserves, cash flow and working capital requirements, general financial condition, applicable withholding and other tax obligations applicable to dividend distributions, contractual restrictions and other factors that our board of directors may deem relevant.

We are a holding company incorporated in the Cayman Islands. Our ability to make distributions or other payments to our shareholders depends substantially on payments from our operating subsidiary, whose ability to make such payments is subject to PRC regulations. Under PRC laws and accounting rules, dividends may be paid only out of distributable profits. Distributable profits with respect to our PRC subsidiaries refers to its after-tax profits as determined under PRC accounting standards, less any recovery of accumulated losses and allocations to statutory funds that it is required to make. For example, it is required to allocate 10% of its after-tax profit to statutory reserves until such reserves reach 50% of WSP China's registered capital. Allocations to these statutory reserves and funds can only be used for specific purposes and are not transferable to us in the form of loans, advances or cash dividends. As a result, our PRC subsidiariesmay not be able to pay dividends to us in any given year if it does not have distributable profits as determined under PRC accounting standards, even if we have profits for the relevant year as determined under U.S. GAAP. Accordingly, if we do not receive dividend distributions from our PRC subsidiaries, our liquidity, financial condition and ability to make dividend distributions will be materially and adversely affected.

Moreover, cash transfers from our PRC subsidiaries to us are subject to the PRC government's currency conversion policy, and our PRC subsidiaries may not be able to obtain the relevant approvals or complete the requisite registrations for distributing dividends to us. Any failure by any of our shareholders or any beneficial owner of our Shares who is a PRC resident to comply with the approval or registration requirements imposed by the State Administration of Foreign Exchange with respect to their investment in us could also subject us to legal sanctions, including a restriction on our PRC subsidiaries' ability to distribute dividends to us. As a result of the foregoing restrictions on our PRC subsidiaries, our ability to pay dividends on our Shares, or indirectly on our ADSs, could be significantly limited.

We may be treated as a PRC resident enterprise for PRC tax purposes and be obligated to withhold PRC income tax on payments of dividends on our Shares and ADSs to investors that are non-resident enterprises of the PRC. The withholding tax rate would generally be 10% on dividends paid to non-resident enterprises and 20% on dividends paid to non-resident individuals, subject to applicable tax treaty reliefs. Pursuant to a tax treaty between the PRC and the United States, a 10% rate will apply to dividends paid to non-resident individuals provided certain conditions are met. In addition, pursuant to a tax treaty between the PRC and Hong Kong, the withholding tax rate may be lowered to 5% if the PRC resident enterprise is at least 25% held by a Hong Kong company and other conditions set forth by the relevant tax authorities have been met. See "Item 3. Key Information—D. Risk Factors—Risks related to doing business in China—We may be treated as a resident enterprise for PRC tax purposes under the New EIT Law, which may subject us to PRC income tax for our income originated both within and outside the PRC and PRC income tax withholding for any dividends we pay to our non-PRC shareholders" in the Company's Annual Report on Form 20-F for the year ended December 31, 2012, which is incorporated herein by reference.

We are furnishing this proxy statement to you, as a holder of our Shares, as part of the solicitation of proxies by the Company's board of directors for use at the extraordinary general meeting described below.

The extraordinary general meeting will be held on , 2014, at , a.m. (Hong Kong time) at , Hong Kong.

If the merger is completed, at the effective time of the merger, each outstanding Share (including Shares represented by ADSs), other than the Excluded Shares, will be cancelled and cease to exsit in exchange for the right to receive $0.32 in cash without interest, and for the avoidance of doubt, because each ADS represents ten Shares, each issued and outstanding ADS (other than ADS that represents Excluded Shares), will represent the right to surrender the ADS in exchange for $3.20 in cash per ADS without interest (less $0.05 per ADS cancellation fees pursuant to the terms of the Deposit Agreement), in each case, net of any applicable withholding taxes, in accordance with the terms and conditions set forth in the merger agreement. At the effective time, all of the Shares will be cancelled and cease to exist. Each Dissenting Share will thereafter represent only the right to receive the fair value of such Share as determined under the Cayman Islands Companies Law. Each Excluded Share other than Dissenting Share will be cancelled for no consideration. At the effective time of the merger, each outstanding ordinary share, par value $1.00 per share, of Merger Sub will be converted into one fully paid and non-assessable ordinary share, par value $1.00 per share, of the surviving company.

Our board of directors, acting upon the unanimous recommendation of the Special Committee of our board of directors:

You are entitled to vote at the extraordinary general meeting if you have Shares registered in your name at the close of business in New York City on , 2014, or if you are a holder of ADSs at the close of business in New York City on , 2014, the share record date and the ADS record date, respectively, for voting at the extraordinary general meeting. If you own ADSs on the ADS record date, you cannot attend or vote at the extraordinary general meeting directly, but you may instruct the ADS depositary (as the registered holder of the Shares underlying the ADSs) on how to vote the Shares underlying your ADSs. The ADS depositary must receive your instructions no later than p.m. (New York City time) on , 2014 in order to ensure that your Shares are properly voted at the extraordinary general meeting. Alternatively, if you own ADSs on the ADS record date, you may vote at the extraordinary general meeting by cancelling your ADSs (and certifying that you have not instructed, and will not instruct, the ADS depositary to vote the Shares represented by your ADSs) before the close of business in New York City on , 2014 and becoming a registered holder of Shares prior to the close of business in New York City on , 2014, the share record date. See "—Procedures for Voting" below for more information relating to the procedure of ADSs cancellation. Each outstanding Share on the share record date entitles the holder to one vote on each matter submitted to the shareholders for approval at the extraordinary general meeting and any adjournment thereof. We expect that, on the share record date, Shares will be issued and outstanding and held by approximately holders of record. If you have Shares registered in your name at the close of business in New York City on the share record date, the deadline for you to lodge your proxy card and vote is , 2014 at p.m. (Hong Kong time).

the ADS depositary for the issuance of ADSs (up to $0.05 per ADS issued) and any applicable stock transfer taxes (if any) and related charges pursuant to the Deposit Agreement.

A quorum of our shareholders is necessary to have a valid shareholders' meeting. The required quorum for the transaction of business at the extraordinary general meeting is the presence, in person or by proxy, of two shareholders holding no less than one-third in nominal value of the total issued and outstanding Shares on the share record date.

We expect, as of the share record date, there will be Shares entitled to be voted at the extraordinary general meeting. In the event that a quorum is not present at the extraordinary general meeting, we currently expect that we will adjourn the extraordinary general meeting to solicit additional proxies in favor of the approval of the merger agreement.

Under the Cayman Islands Companies Law and the merger agreement, we cannot complete the merger unless the merger agreement and the transactions contemplated by the merger agreement, including the merger, are authorized and approved by an affirmative vote of shareholders representing two-thirds or more of the Shares present and voting in person or by proxy as a single class at the extraordinary general meeting.

The Rollover Shareholders together own 150,000,000 Shares, which represents approximately 73.4% of the total outstanding Shares. The Rollover Shareholders together have sufficient votes to constitute a quorum for the extraordinary general meeting and authorize and approve the merger agreement, the plan of merger and the transactions contemplated by the merger agreement, including the merger, at the extraordinary general meeting.

To the extent known by the Company after making reasonable inquiry, except as set forth under the caption "Security Ownership of Certain Beneficial Owners and Management of the Company," no executive officer, director or affiliate of the Company or any member of the Buyer Group currently hold any securities of the Company.

Registered holders of record of our Shares as of the share record date may vote their Shares by attending the extraordinary general meeting and voting their Shares in person or by completing the accompanying proxy card in accordance with the instructions set forth on the proxy card. The deadline to lodge your proxy card is , 2014 at p.m. (Hong Kong time).

Shareholders who hold their Shares in "street name," meaning in the name of a broker, bank or other nominee who is the record holder, must either direct the record holder of their Shares how to vote their Shares or obtain a proxy from the record holder to vote their Shares at the extraordinary general meeting.

Shareholders who have questions or requests for assistance in completing and submitting proxy cards should contact Judy Zhu, our Director of Investor Relationships, at +86 510 8536 0401 or zhuxh@wsphl.com.

If you own ADSs as of the close of business in New York City on , 2014, you cannot attend or vote at the extraordinary general meeting directly, but you may instruct the ADS depositary

(as the registered holder of the Shares underlying the ADSs) how to vote the Shares underlying your ADSs by completing and signing the ADS voting instruction card and returning it in accordance with the instructions printed on it as soon as possible but, in any event, so as to be received by the ADS depositary no later than p.m. (New York City time) on , 2014. The ADS depositary must receive such instructions no later than p.m. (New York City time) on , 2014 in order to endeavor insofar as practicable and permitted under the provisions of or governing Shares to vote or cause to be voted the underlying Shares at the extraordinary general meeting. The ADS depositary will not itself exercise any voting discretion in respect of any Shares. Alternatively, you may vote at the extraordinary general meeting if you cancel your ADSs and, among other things as described below, when presenting voting instructions to the Company certify to the Company that you have not given, and will not give, voting instructions to the ADS depositary as to the ADSs being cancelled, by the close of business in New York City on , 2014 and become a holder of Shares by the close of business in New York City on , 2014, the share record date. The ADS depositary will endeavor, in so far as practicable, to vote or cause to be voted the number of Shares represented by your ADSs in accordance with your voting instructions.

If you hold your ADSs through a financial intermediary such as a broker, bank or other nominee, you must rely on the procedures of the financial intermediary through which you hold your ADSs if you wish to vote.

If you wish to cancel your ADSs, you need to make arrangements to surrender your ADSs to the ADS depositary for cancellation before the close of business in New York City on , 2014, together with (a) delivery instructions for the corresponding Shares (name and address of person who will be the registered holder of Shares), (b) payment of the ADS cancellation fees ($0.05 per ADS to be cancelled) and any applicable taxes. In addition, prior holders of ADSs that attend the meeting will be required to certify at the meeting to the Company that such former holder either (i) held the ADSsas of the applicable ADS record date for the extraordinary general meeting, and has not given, and will not give, voting instructions to the ADS depositary as to the ADSs being cancelled, or has given voting instructions to the ADS depositary as to the ADSs being cancelled but undertakes not to vote the corresponding Shares at the extraordinary general meeting, or (ii) did not hold the ADSs as of the applicable ADS record date for the extraordinary general meeting and undertakes not to vote the corresponding Shares at the extraordinary general meeting. If you hold your ADSs in a brokerage, bank or nominee account, please contact your broker, bank or nominee to find out what actions you need to take to instruct the broker, bank or nominee to cancel the ADSs on your behalf. Upon cancellation of the ADSs, the ADS depositary will arrange for J.P. Morgan Chase Bank N.A.—Hong Kong Branch (DCC), the custodian holding the Shares, to transfer registration of the Shares to the former ADS holder (or a person designated by the former ADS holder). If after registration of Shares in your name you wish to receive a certificate evidencing the Shares registered in your name, you will need to request the registrar of the Shares to issue and mail a certificate to your attention.

All Shares represented by valid proxies will be voted at the extraordinary general meeting in the manner specified by the holder. If a shareholder returns a properly signed proxy card but does not indicate how the shareholder wants to vote, Shares represented by that proxy card will be voted as the proxy determines.

Brokers, banks or other nominees who hold our Shares in "street name" for customers who are the beneficial owners of such Shares may not give a proxy to vote those customers' Shares in the absence of specific instructions from those customers. Such non-votes will be counted toward a quorum but will not be treated as voted at the extraordinary general meeting.

If a shareholder holds Shares through a broker, bank or other nominee and has instructed the broker, bank or other nominee to vote the shareholder's Shares, the shareholder must follow directions received from the broker, bank or such other nominee to change those instructions.

Holders of our ADSs may revoke their voting instructions by notification to the ADS depositary in writing at any time prior to p.m. (New York City time) on , 2014. To do so, a holder of ADSs can complete, date and submit a new ADS voting instruction card to the ADS depositary bearing a later date than the ADS voting instruction card sought to be revoked to the ADS depositary

If you hold your ADSs through a broker, bank or nominee and you have instructed your broker, bank or nominee to give ADS voting instructions to the ADS depositary, you must follow the directions of your broker, bank or nominee to change those instructions.

Shareholders who continue to hold their Shares in their own name until the completion of the merger will have the right to dissent from the merger and receive payment of the fair value of their Shares if the merger is completed, but only if they deliver to the Company, before the vote is taken, a written objection to the merger and subsequently comply with all procedures and requirements of Section 238 of the Cayman Islands Companies Law, which is attached as Annex C to this proxy statement, for the exercise of dissenter rights. The fair value of your Shares as determined under that statute could be more than, the same as, or less than the merger consideration you would receive pursuant to the merger agreement if you do not exercise dissenter rights with respect to your Shares.

ADS HOLDERS WILL NOT HAVE THE RIGHT TO DISSENT FROM THE MERGER AND RECEIVE PAYMENT OF THE FAIR VALUE OF THE SHARES UNDERLYING THEIR ADSs. THE ADS DEPOSITARY WILL NOT ATTEMPT TO EXERCISE ANY DISSENTER RIGHTS WITH RESPECT TO ANY OF THE SHARES THAT IT HOLDS, EVEN IF AN ADS HOLDER REQUESTS THE ADS DEPOSITARY TO DO SO. ADS HOLDERS WISHING TO EXERCISE DISSENTER

RIGHTS MUST SURRENDER THEIR ADSs TO THE ADS DEPOSITARY, PAY THE ADS DEPOSITARY'S FEES REQUIRED FOR THE CANCELLATION OF THE ADSs, PROVIDE INSTRUCTIONS FOR THE REGISTRATION OF THE CORRESPONDING SHARES, AND, WHEN PRESENTING SUCH SHARES TO THE COMPANY FOR EXERCISE OF DISSENTER RIGHTS CERTIFY TO THE COMPANY THAT THEY HAVE NOT GIVEN, AND WILL NOT GIVE, VOTING INSTRUCTIONS AS TO THE ADSs (OR, ALTERNATIVELY, THAT THEY WILL NOT VOTE THE SHARES) BEFORE THE CLOSE OF BUSINESS IN NEW YORK CITY ON , 2014, AND BECOME REGISTERED HOLDERS OF SHARES BY THE CLOSE OF BUSINESS IN THE CAYMAN ISLANDS ON , 2014. THEREAFTER, SUCH FORMER ADS HOLDERS MUST COMPLY WITH THE PROCEDURES AND REQUIREMENTS FOR EXERCISING DISSENTER RIGHTS WITH RESPECT TO THE SHARES UNDER SECTION 238 OF THE CAYMAN ISLANDS COMPANIES LAW. IF THE MERGER IS NOT COMPLETED, THE COMPANY WOULD CONTINUE TO BE A PUBLIC COMPANY IN THE U.S. AND THE COMPANY'S ADSS WOULD CONTINUE TO BE LISTED ON THE NYSE. THE COMPANY'S SHARES ARE NOT LISTED AND CANNOT BE TRADED ON ANY STOCK EXCHANGE OTHER THAN THE NYSE, AND IN SUCH CASE ONLY IN THE FORM OF ADSs. AS A RESULT, IF YOU HAVE CANCELLED YOUR ADSs TO ATTEND THE EXTRAORDINARY GENERAL MEETING AND THE MERGER IS NOT COMPLETED AND YOU WISH TO BE ABLE TO SELL YOUR SHARES ON A STOCK EXCHANGE, YOU WOULD NEED TO DEPOSIT YOUR SHARES INTO THE COMPANY'S AMERICAN DEPOSITARY SHARES PROGRAM FOR THE ISSUANCE OF THE CORRESPONDING NUMBER OF ADSs, SUBJECT TO THE TERMS AND CONDITIONS OF APPLICABLE LAW AND THE DEPOSIT AGREEMENT, INCLUDING, AMONG OTHER THINGS, PAYMENT OF RELEVANT FEES OF THE ADS DEPOSITARY FOR THE ISSUANCE OF ADSS (UP TO $0.05 PER ADS ISSUED) AND ANY APPLICABLE STOCK TRANSFER TAXES (IF ANY) AND RELATED CHARGES PURSUANT TO THE DEPOSIT AGREEMENT.

We are not currently aware of any business to be acted upon at the extraordinary general meeting other than the matters discussed in this proxy statement.

This section of the proxy statement describes the material terms of the merger agreement and the plan of merger but does not purport to describe all of the terms of the merger agreement and the plan of merger. The following summary is qualified in its entirety by reference to the complete text of the merger agreement and the plan of merger, which is attached as Annex A to this proxy statement and incorporated into this proxy statement by reference. You should read the merger agreement and the plan of merger in their entirety because they, and not this proxy statement, are the legal documents that govern the merger. This description of the merger agreement and the plan of merger have been included to provide you with information regarding their terms.

The merger agreement provides for the merger of Merger Sub with and into the Company upon the terms, and subject to the conditions, of the merger agreement and the plan of merger, with the Company as the surviving entity of the merger. If the merger is completed, the Company will cease to be a publicly traded company. The closing of the merger will occur on the fifth business day immediately after all of the closing conditions have been satisfied or waived. At the closing, Merger Sub and the Company will execute the plan of merger and register the plan of merger and other related documents with the Registrar of Companies of the Cayman Islands. The merger will become effective upon such filing or at such later time as may be agreed in writing by Parent, Merger Sub and the Company and specified in the plan of merger.

We expect that the merger will be completed during the first half of 2014, after all conditions to the merger have been satisfied or waived. We cannot specify when, or assure you that, all conditions to the merger will be satisfied or waived; however, we intend to complete the merger as promptly as practicable.

Memorandum and Articles of Association; Directors and Officers of the Surviving Company

Upon completion of the merger, the memorandum and articles of association of Merger Sub, as in effect at the effective time of the merger, will be the memorandum and articles of association of the surviving company, except that at the effective time, the memorandum and articles of association will refer to the name of the surviving company as "WSP Holdings Limited" and the authorized share capital will be described as US$50,000 divided into 50,000 ordinary shares of a nominal or par value of US$1.00 each, until thereafter amended in accordance with the applicable provisions of the Cayman Islands Companies Law and such memorandum and articles of association. The directors of Merger Sub immediately prior to the effective time of the merger will become the directors of the surviving company and the officers of the Company immediately prior to such effective time will become the officers of the surviving company.

At the effective time, each issued and outstanding Share other than the Excluded Shares will be cancelled in exchange for the right to receive $0.32 in cash, without interest and net of any applicable withholding taxes. Each outstanding ADS, other than any ADS that represents Excluded Shares, will represent the right to surrender the ADS in exchange for $3.20 (less any applicable fees, charges and expenses of the ADS depositary payable by ADS holders pursuant to the terms of the Deposit Agreement) in cash, without interest and net of any applicable withholding taxes.

Each Rollover Share will be cancelled and cease to exist without conversion or payment of any cash consideration immediately prior to the effective time of the merger.

Each Dissenting Share will be entitled to receive only the payment resulting from the procedures set forth in Section 238 of the Cayman Islands Companies Law. Please see "Dissenter Rights" beginning on page 100 for additional information.

Each Share owned by Parent, Merger Sub or the Company (as treasury shares, if any), or by any direct or indirect wholly-owned subsidiary of Parent, Merger Sub or the Company, in each case immediately prior to the effective time of the merger, will be cancelled, cease to exist and receive no consideration.

At the effective time of the merger, each outstanding ordinary share, par value $1.00 per share, of Merger Sub will be converted into one fully paid and non-assessable ordinary share, par value $1.00 per share, of the surviving company.

Prior to the effective time of the merger, Parent will appoint a bank or trust company reasonably acceptable to the Company to act as the paying agent (which we refer to as the "paying agent"), and Parent will deposit with the paying agent a cash amount sufficient for the paying agent to make payments under the merger agreement. Promptly after the effective time of the merger, and in any event within three business days after such effective time, the paying agent will mail or deliver to each registered holder of Shares, other than holders of the Excluded Shares (a) a form of letter of transmittal for purposes of specifying how the delivery of the merger consideration to registered holders of the Shares is to be effected and/or (b) instructions for effecting the surrender of any share certificates in exchange for the applicable merger consideration. If you have lost a share certificate, or if it has been stolen or destroyed, then before you will be entitled to receive the per Share merger consideration, you will have to make an affidavit of loss, theft or destruction. Upon the surrender of any share certificates, or an affidavit and indemnity of loss in lieu of share certificates, together with a duly completed letter of transmittal, if applicable, each registered holder of Shares, other than holders of the Excluded Shares, represented by such share certificates and each registered holder of Shares, other than holders of the Excluded Shares, which are not represented by share certificates will receive a check in an amount equal to (a) the number of Shares held multiplied by (b) the per Share merger consideration, without interest and net of any applicable withholding taxes. Meanwhile, promptly after the effective time of the merger, the paying agent will transmit to the ADS depositary a cash amount equal to (a) the number of ADSs issued and outstanding multiplied by (b) the per ADS merger consideration. The ADS depositary will distribute the merger consideration for the ADSs (less any applicable fees, charges and expenses of the ADS depositary payable by ADS holders pursuant to the terms of the Deposit Agreement) to ADS holders pro rata to their holdings of ADSs, without interest and net of any applicable withholding taxes, upon surrender by them of the ADSs.

At the effective time of the merger, the register of members of the Company will be closed and thereafter there will be no further registration of transfers on the register of members of the surviving company of Shares that were outstanding immediately prior to the effective time of the merger. From and after the effective time of the merger, the holders of share certificates or Shares not represented by share certificates will cease to have any rights with respect to such Shares except as otherwise provided in the merger agreement or by applicable laws.

Any portion of the merger consideration deposited with the paying agent which remains undistributed to the shareholders of the Company for twelve months after the effective time of the merger will be delivered to Parent upon demand, and any holders of Shares or ADSs who have not complied with the exchange and payment procedures described above by the end of the twelfth month after the effective time of the merger will thereafter only look to Parent for the per Share or per ADS merger consideration, as applicable, to which such holder may be entitled.

The merger agreement contains representations and warranties made by the Company to Parent and Merger Sub and representations and warranties made by Parent and Merger Sub to the Company, in each case, as of specific dates. The statements embodied in those representations and warranties were made for purposes of the merger agreement and are subject to important qualifications and limitations agreed by the parties in connection with negotiating the terms of the merger agreement (including the disclosure letters delivered by the Company in connection therewith but not reflected in the merger agreement). In addition, some of those representations and warranties may be subject to a contractual standard of materiality different from that generally applicable to shareholders, may have been made for the principal purposes of establishing the circumstances in which a party to the merger agreement may have the right not to close the merger if the representations and warranties of the other party prove to be untrue due to a change in circumstance or otherwise and allocating risk between the parties to the merger agreement rather than establishing matters as facts. Moreover, information concerning the subject matter of the representations and warranties, which do not purport to be accurate as of the date of this proxy statement, may have changed since the date of the merger agreement and subsequent developments or new information qualifying a representation or warranty may have been included in this proxy statement.

The representations and warranties made by the Company to Parent and Merger Sub include representations and warranties relating to, among other things:

Many of the representations and warranties in the merger agreement made by the Company are qualified as to "materiality" or "Company Material Adverse Effect." Under the merger agreement, a Company Material Adverse Effect means any change, effect, event or development, individually or in the aggregate, that has had a material adverse effect on the business, financial condition or results of operations of the Company and its subsidiaries, taken as a whole. However, no change, effect, event or development, by itself or in the aggregate, directly or indirectly resulting from, relating to or arising out of any of the following shall be deemed to be or constitute a Company Material Adverse Effect, or be taken into account when determining whether a Company Material Adverse Effect has occurred or may, would or could occur:

except to the extent such effects directly or indirectly resulting from, arising out of, attributable to or related to the matters described in the first five bullet points above materially and disproportionately affect the Company and its subsidiaries, taken as a whole, as compared to other companies that conduct business in the countries and regions in the world and in the industries in which the Company and its subsidiaries operate or conduct business (in which case, such effects may be taken into account when determining whether a Company Material Adverse Effect has occurred, but only to the extent of such disproportionate effects).

The representations and warranties made by each of Parent and Merger Sub to the Company include representations and warranties relating to, among other things:

Under the merger agreement, the Company has agreed that, subject to certain exceptions in the merger agreement and the company disclosure letter, from the date of the merger agreement until the earlier of the effective time of the merger or the termination of the merger agreement, the Company and its subsidiaries will conduct their businesses in the ordinary course in all material respects, and will use their reasonable best efforts, consistent with past practice, to preserve substantially intact its business organization and preserve their relationships with material customers, suppliers and others with whom the Company has significant business relations as is reasonably necessary.

Subject to certain exceptions set forth in the merger agreement and the disclosure letter the Company delivered in connection with the merger agreement, unless Parent gives its approval (which

approval cannot be unreasonably withheld, conditioned or delayed), the Company will not and will not permit any of its subsidiaries to, among other things:

Each of Parent and Merger Sub will take all actions necessary to obtain sufficient equity financing to finance the merger and pay related fees and expenses by (i) maintaining in effect the equity commitment letter, (ii) satisfying on a timely basis all conditions applicable to Parent and Merger Sub in the equity commitment letter that are within their control, (iii) consummating the financing contemplated by the equity commitment letter at or prior to the closing of the merger (in any event prior to May 31, 2014), and (iv) fully enforcing General Transactions' obligations under the equity commitment letter. In the event that the Company files any lawsuits or take any other actions against General Transactions in order to fully enforce General Transactions' obligations under the equity commitment letter or the limited guarantee, during the pendency of such lawsuits or other actions, Parent and Merger Sub will consult, cooperate and coordinate with the Company regarding any

lawsuits or other actions that the Company may file or take against General Transactions arising out of the merger agreement, the equity commitment letter, the limited guarantee, the transactions contemplated by the merger agreement or any related matter. Each of Parent and Merger Sub will keep the Company fully and promptly apprised as to any material developments relating to the equity financing.

Neither Parent nor Merger Sub will amend or waive any term of the equity commitment letter without the prior written consent of the Company and the board of directors of the Company or the Special Committee. Parent will promptly notify the Company of (i) the expiration or termination of the equity commitment letter, or (ii) any refusal by General Transactions to provide or any reservation by General Transactions regarding its obligation or ability to provide, the full financing contemplated by the equity commitment letter.

Prior to the closing of the merger, none of Parent, Merger Sub or any of their affiliates will enter into any arrangements with any person (other than General Transactions) (i) pursuant to which such person agrees to provide equity, debt or other financing for the merger on an exclusive basis to Parent, Merger Sub or any of its affiliates, or (ii) pursuant to which such person agrees to refrain from providing to any person other than Parent and Merger Sub or any of its affiliates (including General Transactions) any equity, debt or other financing for a transaction involving the Company or any of its subsidiaries, including in connection with making an acquisition proposal, or (iii) on terms that could reasonably be expected to prevent or hinder such person from providing any equity, debt or other financing for a transaction involving the Company or any of its subsidiaries, including in connection with making an acquisition proposal.

From the date of the merger agreement until the earlier to occur of the effective time of the merger or the termination of the merger agreement, none of the Company, any of its subsidiaries, or any officer, director, employee or representative of the Company or any of its subsidiaries may:

Upon signing the merger agreement, the Company is required to instruct its representatives that are engaged in ongoing discussions with any persons (other than Parent, Merger Sub or any of their Representatives) with respect to an acquisition proposal to cease any such discussions.

Notwithstanding the foregoing, (i) if the Company receives an unsolicited acquisition proposal, the board of directors, acting through the Special Committee, may contact such persons making such acquisition proposal to clarify and understand the terms and conditions thereof in order to assess whether such acquisition proposal is reasonably expected to lead to a superior proposal, (ii) if the Company receives an unsolicited bona fide, written acquisition proposal that the board of directors, acting through the Special Committee, determines in good faith, after consultation with its financial advisor and outside legal counsel, either constitutes or is reasonably expected to lead to a superior proposal, the board of directors, acting through the Special Committee, may participate or engage in discussions or negotiations with any persons making such acquisition proposal if it determines in good faith (after consultation with its legal counsel) that failure to take such action would reasonably be expected to be inconsistent with its fiduciary duties, and/or (iii) if the Company receives an unsolicited bona fide, written acquisition proposal the board of directors, acting through the Special Committee, determines in good faith, after consultation with its financial advisor and outside legal counsel, either constitutes or is reasonably expected to lead to a superior proposal, the board of directors, acting through the Special Committee, may furnish, pursuant to a confidentiality agreement, to such persons making such acquisition proposal, any non-public information relating to the Company or any of its subsidiaries, or afford to any such persons access to the business, properties, assets, books, records or other non-public information, or to any personnel, of the Company or any of its subsidiaries, if the board of directors, acting through the Special Committee, determines in good faith (after consultation with its legal counsel) that failure to take such action would reasonably be expected to be inconsistent with its fiduciary duties. Notwithstanding the foregoing, the Company will not provide any commercially sensitive non-public information to any competitor in connection with the foregoing, except in a manner consistent with the Company's past practice in dealing with the disclosure of such information in the context of considering acquisition proposals.

In this proxy statement, an "acquisition proposal" means any offer or proposal (other than by Parent or Merger Sub) to engage in any transaction involving (i) the purchase or other acquisition by any person or group, directly or indirectly, of more than 20% of the Shares outstanding as of the consummation of such purchase or acquisition, or any tender offer or exchange offer by any person or group that, if consummated in accordance with its terms, would result in such person or group beneficially owning more than 20% of the Shares outstanding as of the consummation of such tender or exchange offer; or (ii) a sale, transfer, acquisition or disposition of more than 20% of the consoliated assets of the Company and its subsidiaries taken as a whole.

In this proxy statement, a "superior proposal" means any bona fide written offer or proposal (other than by Parent or Merger Sub) to engage in any transaction involving (i) the purchase or other acquisition by any person or group, directly or indirectly, of more than 66²/3% of the Shares outstanding as of the consummation of such purchase or acquisition, or any tender offer or exchange offer by any person or group that, if consummated in accordance with its terms, would result in such person or group beneficially owning more than 66²/3% of the Shares outstanding as of the consummation of such tender or exchange offer; or (ii) a sale, transfer, acquisition or disposition of more than 66²/3% of the consoliated assets of the Company and its subsidiaries taken as a whole, in each case, on terms that the board of directors (acting through the Special Committee) shall have determined in good faith, after consultation with its financial advisor and outside legal counsel, taking into account relevant legal, financial and regulatory aspects of such proposal and the likelihood of consummation of such transaction, would be more favorable to the holders of Shares (other than the Rollover Shareholders) than the merger.

The Company has agreed in the merger agreement that the board of directors will recommend that the holders of Shares authorize the merger agreement and the plan of merger, and that the board of directors, including the Special Committee, will not withhold, withdraw, amend or modify in a manner adverse to Parent in any material respect, or publicly propose to withhold, withdraw, amend or modify in a manner adverse to Parent in any material respect, the recommendation to the shareholders of the Company to authorize the merger agreement and the plan of merger. However, a "stop, look and listen" communication by the board of directors or the Special Committee to the shareholders of the Company pursuant to Rule 14d-9(f) of the Exchange Act, is not prohibited, and the board of directors and Special Committee may make any disclose to the holders of Shares that the board of directors or the Special Committee determines in good faith, after consultation with its outside counsel, that the failure to do o would reasonably be expected to be inconsistent with its fiduciary duties to the shareholders under applicable laws.

Notwithstanding the above, at any time prior to the effective time of the merger, the board of directors, acting through the Special Committee, may change its recommendations to the shareholders if:

The Company, in cooperation with and subject to the approval of the Special Committee, will establish a record date for and duly call an extraordinary general meeting of its shareholders as promptly as practicable after the date hereof, solicit the authorization of the merger agreement and the plan of merger by the shareholders of the Company, and include in this proxy statement the recommendation by the board of directors to authorize the merger agreement and plan of merger. However, the Company may adjourn the shareholders meeting to the extent required by applicable laws, if there are insufficient Shares represented at the meeting to constitute a quorum, or if in the good faith judgment of the board of directors or the Special Committee, such adjournment is consistent with its fiduciary duties.

In the event the board of directors, acting through the Special Committee, elects to change its recommendation to the shareholders of the Company to authorize the merger agreement and the plan of merger, the Company will not be required to submit the merger agreement to the shareholders for the purpose of obtaining the shareholder approvals.

The merger agreement contains additional agreements between the Company and Parent and/or Merger Sub relating to, among other things:

The consummation of the merger is subject to the satisfaction or waiver by mutual agreement of Parent and the Company (subject to the approval of the Special Committee) of the following conditions:

The obligations of Parent and Merger Sub to consummate the merger are also subject to the satisfaction, or waiver by Parent, of the following conditions:

The obligations of the Company to consummate the merger are also subject to the satisfaction, or waiver by the Company, of the following conditions:

The merger agreement may be terminated at any time prior to the effective time of the merger:

The Company will act through the Special Committee to determine whether to exercise its termination right under the merger agreement.

The Company is required to pay Parent a termination fee of $1.0 million within two business days after termination if:

Parent is required to pay the Company a termination fee of $1.0 million within two business days of termination if:

Except as set forth above, whether or not the merger is completed, all costs and expenses incurred in connection with the merger agreement and the transactions contemplated thereby will be paid by the party incurring such costs and expenses except as otherwise provided in the merger agreement.

The merger agreement may not be amended except by an instrument in writing signed on behalf of the Company, Parent and Merger Sub. In addition, (a) any amendment by the Company will require the approval of the Special Committee, and (b) after approval of the merger agreement by the shareholders of the Company, no amendment that requires the approval of the shareholders of the Company under the Cayman Islands Companies Law will be made to the merger agreement without obtaining such shareholder approval for such amendment.

At any time prior to the effective time of the merger, Parent and Merger Sub, as one party, and the Company, as one party, may (a) extend the time for the performance of any of the obligations or other acts of the other party under the merger agreement, (b) waive any inaccuracies in the representations and warranties of the other party contained in the merger agreement or in any document delivered pursuant to the merger agreement, or (c) waive compliance with any of the

agreements or conditions for the benefit of such party or parties to the merger agreement contained in the merger agreement.

Pursuant to the merger agreement, in the event of any breach or threatened breach by either party of the merger agreement of any of their respective covenants or obligations thereunder or in connection with the merger, the Company, on the one hand, and Parent and Merger Sub and/or General Transactions, on the other hand, will be entitled to an injunction or injunctions to prevent or restrain breaches or threatened breaches of the merger agreement by the other, and to specifically enforce the terms and provisions of the merger agreement and any other agreements or arrangements implementing the merger to prevent breaches or threatened breaches of, or to enforce compliance with, the covenants and obligations of the other under the merger agreement and the merger. This right includes the right of the Company to cause Parent and Merger Sub to fully enforce the equity commitment letter against HDS to the fullest extent permissible pursuant to applicable laws and to thereafter cause the merger to be consummated.

Subject to any equitable remedies the Company may be entitled to, our right to receive payment of a termination fee of $1.0 million from Parent (or General Transactions, if requested to pay by the Company), is our sole and exclusive remedy for any loss or damage suffered as a result of the failure of the merger to be consummated or for a breach or failure to perform under the merger agreement or otherwise.

Subject to any equitable remedies Parent or Merger Sub may be entitled to, Parent's right to receive payment of a termination fee of $1.0 million from us, is the sole and exclusive remedy of Parent and Merger Sub against us for any loss or damage suffered as a result of the failure of the merger to be consummated or for a breach or failure to perform under the merger agreement or otherwise.

No provision has been made to (a) grant the Company's shareholders or ADS holders access to corporate files of the Company and other parties to the merger or any of their respective affiliates or (b) obtain counsel or appraisal services at the expense of the Company or any other such party or affiliate.

The following is a brief summary of the rights of holders of the Shares to object to the merger and receive payment of the fair value of their Shares ("dissenter rights"). This summary is not a complete statement of the law, and is qualified in its entirety by the complete text of Section 238 of the Cayman Islands Companies Law, a copy of which is attached as Annex C to this proxy statement. If you are contemplating the possibility of objecting to the merger, you should carefully review the text of Annex C, particularly the procedural steps required to exercise your dissenter rights. These procedures are complex and you should consult your Cayman Islands legal counsel. If you do not fully and precisely satisfy the procedural requirements of the Cayman Islands Companies Law, you will lose your dissenter rights.

A dissenting registered shareholder of the Company is entitled to payment of the fair value of his or her Shares upon dissenting from the merger in accordance with Section 238 of the Cayman Islands Companies Law.

The exercise of your dissenter rights will preclude the exercise of any other rights by virtue of holding Shares in connection with the merger, other than the right to seek relief on the grounds that the merger is void or unlawful. To exercise your dissenter rights, the following procedures must be followed:

All notices and petitions must be executed by or for the shareholder of record, fully and correctly, as such shareholder's name appears on the register of members of the Company. If the Shares are owned of record in a fiduciary capacity, such as by a trustee, guardian or custodian, these notices must be executed by or for the fiduciary. If the Shares are owned by or for more than one person such notices and petitions must be executed by or for all joint owners. An authorized agent, including an agent for two or more joint owners, may execute the notices or petitions for a shareholder of record. However, the agent must identify the record owner and expressly disclose the fact that, in exercising the notice, he is acting as agent for the record owner. A person having a beneficial interest in Shares held of record in the name of another person, such as a broker, bank or nominee, must act promptly to cause the record holder to follow the steps summarized above and in a timely manner to exercise whatever dissenter rights attached to the Shares.

You must be a registered holder of Shares in order to exercise your dissenter rights. A holder of ADSs who wishes to dissent must surrender his or her ADSs to the ADS depositary and pay the fee of ADS depositary to withdraw his or her Shares and then become a record holder of such Shares and comply with the procedures described above in order to exercise the dissenter rights with respect to the Shares prior to the extraordinary general meeting. The ADS depositary will not exercise dissenter rights on behalf of a holder of ADSs, and any Notice of Dissent delivered to the ADS depositary will not be effective under the Cayman Islands Companies Law. If you wish to cancel your ADSs, please contact the ADS depositary's office at 1 Chase Manhattan Plaza, Floor 21, New York, New York, 10005-1401. If the merger is not completed, the Company would continue to be a public company in the U.S. and the Company's ADSs would continue to be listed on the NYSE. The Company's Shares are not listed and cannot be traded on any stock exchange other than the NYSE, and in such case only in the form of ADSs. As a result, if you have cancelled your ADSs to attend the extraordinary general meeting and the merger is not completed and you wish to be able to sell your Shares on a stock exchange, you would need to deposit your Shares into the Company's American depositary shares program for the issuance of the corresponding number of ADSs, subject to the terms and conditions of applicable law and the Deposit Agreement, including, among other things, payment of relevant fees of the ADS depositary for the issuance of ADSs (up to $0.05 per ADS issued) and any applicable stock transfer taxes (if any) and related charges pursuant to the Deposit Agreement.

If you do not satisfy each of these requirements, you cannot exercise dissenter rights and will be bound by the terms of the merger agreement. Submitting a proxy card that does not direct how the Shares represented by that proxy are to be voted will give the proxy discretion to vote as it determines appropriate. In addition, failure to vote your Shares, or a vote against the proposal to authorize and approve the merger agreement, the plan of merger and the transactions contemplated by the merger agreement, including the merger, will not alone satisfy the notice requirement referred to above. You must send all notices to the Company to ADS cancellation, Attention: Judy Zhu.

If you are considering dissenting, you should be aware that the fair value of your Shares determined under Section 238 of the Cayman Islands Companies Law could be more than, the same as, or less than the $0.32 in cash without interest for each Share of the Company that you would otherwise receive as consideration in the merger. You also should be aware that investment banking opinions as to the fairness, from a financial point of view, of the consideration payable in a sale transaction, such as the merger, are not opinions as to, and do not in any manner address, fair value under Section 238. In addition, in any proceedings for determination of the fair value of the Shares covered by a Notice of Dissent, the Company and General Transactions intend to assert that the per Share Merger consideration of $3.20 is equal to the fair value of each of your Shares.

The provisions of Section 238 of the Cayman Islands Companies Law are technical and complex. If you fail to comply strictly with the procedures set forth in Section 238, you will lose your dissenter rights. You should consult your Cayman Islands legal counsel if you wish to exercise dissenter rights.

The following is a general discussion of material U.S. federal income tax consequences of the merger, under current law, to U.S. Holders (as defined below) of the Shares who exchange Shares for cash pursuant to the merger agreement. For purposes of this discussion, except as otherwise noted, references to Shares include ownership interests in Shares through ADSs and references to the merger include any exchange of Shares for cash pursuant to dissenter rights. This discussion is based on the federal income tax laws of the United States as of the date of this proxy statement, including the U.S. Internal Revenue Code of 1986, as amended, referred to as the "Code," final and temporary U.S. Treasury Regulations promulgated thereunder, administrative pronouncements, judicial decisions, and other applicable authorities, all as of the date hereof. All of the foregoing authorities are subject to change, possibly on a retroactive basis, and to differing interpretation, which may result in tax consequences different from those described below. We have not sought any ruling from the U.S. Internal Revenue Service, referred to as the "IRS." This discussion is not binding on the IRS, and the IRS may challenge any of the conclusions set forth below and a U.S. court may sustain such a challenge.

This discussion does not address any U.S. federal estate, gift, or other non-income tax, or any state, local, or non-U.S. tax, consequences of the merger. This discussion is a summary for general information purposes only and does not consider all aspects of U.S. federal income taxation that may be relevant to particular shareholders in light of their individual investment circumstances or to certain types of shareholders subject to special tax rules, including holders that are (i) banks, financial institutions, or insurance companies; (ii) regulated investment companies, mutual funds, or real estate investment trusts; (iii) brokers or dealers in securities or currencies; (iv) traders that elect to apply a mark-to-market accounting method; (v) tax-exempt organizations and entities; (vi) holders that own Shares as part of a straddle, hedge, constructive sale, conversion transaction, or other integrated investment; (vii) holders that acquired Shares in connection with the exercise of employee share options or otherwise as compensation for services; (viii) U.S. Holders (as defined below) that have a "functional currency" other than the U.S. dollar; (ix) retirement plans, individual retirement accounts, or other tax-deferred accounts; (x) U.S. expatriates or entities subject to the U.S. anti-inversion tax rules; (xi) persons subject to alternative minimum tax; (xii) U.S. Holders that actually or constructively own 10% or more of our voting stock or (xiii) holders that are not U.S. Holders. This discussion assumes that Shares are held as capital assets, within the meaning of Section 1221 of the Code, at all relevant times, and that each U.S. Holders is an unaffiliated security holder.

As used herein, a "U.S. Holder" is any beneficial owner of Shares that is (i) a citizen or individual resident of the United States for U.S. federal income tax purposes; (ii) a corporation (or other entity treated as a corporation for U.S. federal income tax purposes) created or organized under the laws of the United States, any state thereof, or the District of Columbia; (iii) an estate the income of which is subject to U.S. federal income taxation regardless of its source; or (iv) a trust which (a) is subject to the primary jurisdiction of a court within the United States and for which one or more U.S. persons have authority to control all substantial decisions, or (b) has a valid election in effect under applicable U.S. Treasury Regulations to be treated as a U.S. person.

If a partnership (including any entity classified as a partnership for U.S. federal income tax purposes) is a beneficial owner of Shares, the U.S. federal income tax treatment of a partner in the partnership generally will depend on the status of the partner and the activities of the partner and the partnership. Any partnership, or partner of such a partnership, holding Shares is urged to consult its own tax advisor.

ALL HOLDERS OF SHARES SHOULD CONSULT THEIR TAX ADVISORS REGARDING THE SPECIFIC TAX CONSEQUENCES OF THE MERGER IN LIGHT OF THEIR PARTICULAR SITUATIONS, INCLUDING THE APPLICABILITY AND EFFECT OF U.S. FEDERAL, STATE, LOCAL, NON-U.S. AND OTHER LAWS.

For U.S. federal income tax purposes, the merger will be treated as a taxable sale of Shares for cash. Accordingly, but subject to the discussion under "Passive Foreign Investment Company" below, the U.S. federal income tax consequences of the receipt of cash in exchange for a Share generally will be that a U.S. Holder will recognize gain or loss in an amount equal to the difference between (i) the amount of cash received (including any taxes withheld or cancellation fees paid pursuant to the Deposit Agreement) and (ii) such U.S. Holder's adjusted tax basis in the Shares exchanged therefor. Subject to the discussion under "Passive Foreign Investment Company" below, such recognized gain or loss will generally be capital gain or loss, and will constitute long-term capital gain or loss if the U.S. Holder's holding period for the Shares exchanged is greater than one year at the effective time of the merger. In the event that a U.S. Holder exercises dissenter rights, any cash received that is attributable to interest generally will be treated as ordinary income for U.S. federal income tax purposes.

Long-term capital gains of non-corporate U.S. Holders generally are subject to U.S. federal income tax at reduced rates. The ability to use any capital loss to offset other income or gain is subject to certain limitations under the Code. If a U.S. Holder acquired different blocks of Shares at different times and different prices, such U.S. Holder must determine the adjusted tax basis and holding period separately with respect to each such block of Shares.

Any gain or loss recognized by U.S. Holders generally will be treated as United States source gain or loss. However, in the event that we are deemed to be a PRC "resident enterprise" under the PRC tax law and gain from the disposition of the Shares is subject to tax in the PRC, you may be eligible to elect to treat such gain as PRC source gain under the income tax treaty between the United States and the PRC (the Agreement Between the Government of the United States of America and the Government of the People's Republic of China for the Avoidance of Double Taxation and the Prevention of Tax Evasion With Respect to Taxes on Income, referred to as the "Treaty"). If you are not eligible for the benefits of the Treaty or you fail to make the election to treat any gain as PRC source, then you may not be able to use the foreign tax credit arising from any PRC tax imposed on the exchange of Shares pursuant to the merger unless such credit can be applied (subject to applicable limitations) against tax due on other income treated as derived from foreign sources. U.S. Holders are urged to consult their tax advisors regarding the tax consequences if PRC tax is imposed on gain on a disposition of our Shares, including the availability of the foreign tax credit under their particular circumstances.

Based on the past composition of our income and valuation of our assets, including goodwill, we believe that we were not a passive foreign investment company, or a "PFIC," for U.S. federal income tax purposes for our taxable year ended December 31, 2012, and we do not expect to become one for our current taxable year, although there can be no assurance in this regard.

In general, we will be a PFIC for any taxable year in which (i) at least 75% of our gross income is passive income or (ii) at least 50% of the value of our assets (based on an average of the quarterly values) is attributable to assets that produce or are held for the production of passive income. For this purpose, passive income generally includes dividends, interest, royalties and rents (other than royalties and rents derived in the active conduct of a trade or business and not derived from a related person). If we own, directly or indirectly, at least 25% (by value) of the stock of another corporation, we will be treated, for purposes of the PFIC tests, as owning our proportionate share of the other corporation's assets and receiving our proportionate share of the other corporation's income. The determination of whether we are a PFIC is made annually. Accordingly, it is possible that we may become a PFIC in the current taxable year due to changes in our asset or income composition. Because we have valued our goodwill based on the market value of the ADSs, a decrease in the price of the ADSs may also result in our becoming a PFIC.

If we are a PFIC for the current taxable year or have been a PFIC during any prior year in which a U.S. Holder held Shares, and the U.S. Holder has not made a valid mark-to-market election or qualified electing fund election, any gain recognized by such U.S. Holder on the disposition of Shares generally would be allocated ratably over such U.S. Holder's holding period for the Shares. The amount allocated to the taxable year of the disposition and to any year before we became a PFIC would be treated as ordinary income. The amount allocated to each other taxable year would be subject to tax at the highest rate in effect for that year and the interest charge generally applicable to underpayments of tax would be imposed on the resulting tax attributable to each such year. If a U.S. Holder has made a valid mark-to-market with respect to its Shares, any gain the U.S. Holder recognizes would be treated as ordinary income and any loss would be treated as ordinary loss, but only to the extent of the net amount previously included in income as a result of the mark-to-market election.

If we are a PFIC for the current taxable year or have been a PFIC during any prior year in which a U.S. Holder held Shares, a U.S. Holder generally would be required to file IRS Form 8621 with respect to the disposition of Shares. The PFIC rules are complex, and each U.S. Holder should consult its own tax advisors regarding the applicable consequences of the merger to it if we are a PFIC or have been a PFIC during any prior year in which such U.S. Holder held Shares.

A U.S. Holder generally will be subject to information reporting with respect to the amount of cash received in the merger, unless such U.S. Holder is a corporation or other exempt recipient. A U.S. Holder may also be subject to backup withholding unless the U.S. Holder is an exempt recipient and, when required, demonstrates this fact or provides a taxpayer identification number, makes certain certifications on IRS Form W-9, and otherwise complies with the applicable requirements. A U.S. Holder that does not provide its correct taxpayer identification number may also be subject to penalties imposed by the IRS.

Backup withholding is not an additional tax and any amounts withheld under the backup withholding rules may be refunded or credited against a U.S. Holder's U.S. federal income tax liability, if any, provided that the required procedures are followed. U.S. Holders should consult their tax advisors as to their qualification for exemption from backup withholding and the procedure for obtaining such an exemption.

Certain U.S. Holders who hold the Company's Shares or ADSs in physical form may be required to report the disposition of such Shares or ADSs on IRS Form 8938. Each U.S. Holder should consult its tax advisor concerning its reporting obligations with respect to a disposal of Shares or ADSs.

For taxable years beginning after December 31, 2012, a U.S. Holder that is an individual or estate, or a trust that does not fall into a special class of trusts that is exempt from such tax, will be subject to a 3.8% tax on the lesser of (1) such holder's "net investment income" (or undistributed "net investment income" in the case of an estate or trust) for the relevant taxable year and (2) the excess of such holder's modified adjusted gross income for the taxable year over a certain threshold (which in the case of individuals will be between $125,000 and $250,000, depending on the individual's circumstances). A U.S. Holder's net investment income generally will include gains from the sale or other disposition of capital assets. U.S. Holders that are individuals, estates or trusts should consult their tax advisors regarding the effect, if any, of this tax on their ownership and disposition of their Shares.

Under the EIT Law, which took effect on January 1, 2008, enterprises established outside of China whose "de facto management bodies" are located in the PRC are considered "resident enterprises," and thus will generally be subject to the enterprise income tax at the rate of 25% on their global income. On December 6, 2007, the State Council adopted the Regulation on the Implementation of PRC Enterprise Income Tax Law, effective as of January 1, 2008, which defines the "de facto management body" as an establishment that has substantial management and control over the business, personnel, accounts and properties of an enterprise. Under the EIT Law and its implementation regulations, PRC income tax at the rate of 10% is applicable to any gain recognized on receipt of cash by a "non-resident enterprise" from transfer of its equity in a PRC resident enterprise, provided that the "non-resident enterprise" (i) does not have an establishment or place of business in the PRC or (ii) has an establishment or place of business in the PRC, but the relevant income is not effectively connected with the establishment or place of business, to the extent such gain is derived from sources within the PRC. Under the Individual Income Tax Law, an individual's PRC-source income from disposition of capital asset is subject to PRC income tax at the rate of 20%. Reliefs from these taxes could be sought from applicable Income Tax Treaties with China.

Although there has not been a definitive determination of the Company's status by the PRC tax authorities, the Company does not believe that it should be considered a resident enterprise under the EIT Law or that the gain recognized on the receipt of cash for our Shares should otherwise be subject to PRC tax to holders of such shares that are not PRC residents. In addition, under the Circular on Strengthening the Administration of Enterprises Income Tax on Non-resident Enterprises' Equity Transfer Income ("Circular 698," Guo Shui Han [2009] No. 698), issued by the State Administration of Taxation, which became effective as of January 1, 2008, and the Circular Concerning Various Questions on the Administration of Enterprises Income Tax on Non-resident Enterprises (Gong Gao [2011] No. 24) issued by the State Administration of Taxation, which became effective as of April 1, 2011, if any non-resident enterprise transfers equity of a PRC resident enterprise, the non-resident enterprise may be subject to a 10% PRC income tax on the gain from such equity transfer; provided, however, that any purchase or sale of equity through the open market will not be subject to such taxation. Where the non-resident enterprise indirectly holds and transfers equity of a PRC resident enterprise held through an offshore holding company, which was established in a jurisdiction with either (i) an actual rate of tax of less than 12.5% or (ii) a tax exemption for the income arising out of the disposition, the non-resident enterprise is required to file with the relevant taxation authorities certain information about the transfer. Where any such taxation authorities, upon review and examination of the documents submitted by the non-resident enterprise, or otherwise under applicable PRC law, deem such offshore holding company to be a vehicle incorporated for the purpose of tax evasion, they have the power to re-classify the offshore share transfer transaction, deny the existence of the offshore holding company and impose a 10% income tax on the gain from such offshore share transfer after an examination by the State Administration of Taxation. Although there has not been a definitive determination on whether a purchase or sale of a public company's shares or ADSs would be subject to Circular 698, the Company does not believe that the gain recognized on the receipt of cash for its Shares or ADSs pursuant to the merger by its corporate shareholders who are not PRC residents should be subject to Circular 698. If, however, the PRC tax authorities were to invoke Circular 698 and impose tax on the receipt of cash for its Shares or ADSs, then any gain recognized on the receipt of cash for its Shares or ADSs pursuant to the merger by its corporate shareholders who are not PRC residents could be treated as PRC-source income that would be subject to PRC income tax (subject to applicable treaty relief).

You should consult your own tax advisor for a full understanding of the tax consequences of the merger to you, including any PRC tax consequences.

The Cayman Islands currently have no form of income, corporate or capital gains tax and no estate duty, inheritance tax or gift tax. No taxes, fees or charges will be 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 the merger or the receipt of cash for our Shares under the terms of the merger. This is subject to the qualification that (i) Cayman Islands stamp duty may be payable if any transaction documents are brought to or executed or produced before a court in the Cayman Islands, and (ii) registration fees will be payable to the Registrar of Companies to register the plan of merger.

If the merger is completed, we will not have public shareholders and there will be no public participants in any future shareholders' meeting. However, if the merger is not completed, an annual general meeting is expected to be held in the fourth quarter of 2014.

We are subject to the reporting requirements of the Securities Exchange Act of 1934, as amended, applicable to foreign private issuers and we file or furnish our annual and current reports and other information with the SEC.

(b) Certain Adjustments. The Per Share Merger Consideration and/or the Per ADS Merger Consideration, as applicable, shall be adjusted appropriately to reflect the effect of any share split, reverse share split, share dividend (including any dividend or distribution of securities convertible into Company Shares), reclassification, combination, exchange of shares, change or readjustment in the ratio of Company Shares represented by each ADS or other like change with respect to Company Shares occurring, or with a record date, on or after the date hereof and prior to the Effective Time, and such adjustment to the Per Share Merger Consideration and/or the Per ADS Merger Consideration, as applicable, shall provide to the holders of Company Shares (including Company Shares represented by ADSs) the same economic effect as contemplated by this Agreement prior to such action.

(c) Statutory Dissenters Rights.

(d) Company Options. Neither Parent nor Merger Sub shall assume any Company Options in connection with the Merger or any other transactions contemplated by this Agreement. Upon the terms and subject to the conditions set forth in this Agreement, except as otherwise agreed to by Parent and a holder of a Company Option, the Company shall take such action as may be necessary so that immediately prior to the Effective Time, (i) the vesting of each Company Option that remains outstanding as of immediately prior to the Effective Time shall be accelerated in full, (ii) each Company Option that remains outstanding as of immediately prior to the Effective Time shall be cancelled and terminated as of the Effective Time, and (iii) each holder of each such Company Option shall be paid by the Surviving Corporation at or promptly after the Effective Time, subject to Section 2.8(e), an amount in cash (without interest), if any, equal to the product obtained by multiplying (x) the aggregate number of Company Shares that were issuable upon exercise of such Company Option immediately prior to the Effective Time, by (y) the difference between the Per Share Merger Consideration and the per share exercise price of such Company Option (the "Option Consideration") (it being understood and agreed that such exercise price shall not actually be paid to the Company by the holder of a Company Option); provided that if the exercise price per share of any such Company Option is equal to or greater than the Per Share Merger Consideration, such Company Option shall be canceled and terminated without any cash payment being made in respect thereof.

(a) Paying Agent. Prior to the Closing, Parent shall select a bank or trust company reasonably acceptable to the Company to act as the paying agent for the Merger (the "Paying Agent") and, in connection therewith, shall enter into an agreement with the Paying Agent in a form reasonably acceptable to the Company.

(b) Exchange Fund. Prior to the Effective Time, Parent shall deposit (or cause to be deposited) with the Paying Agent, for payment to the holders of Company Shares (including Company Shares represented by ADSs) and Company Options pursuant to the provisions of this Article II, an amount of cash equal to the aggregate consideration to which holders of Company Shares (including Company Shares represented by ADSs) and Company Options become entitled under this Article II. Until disbursed in accordance with the terms and conditions of this Agreement, such funds shall be invested by the Paying Agent, as directed by Parent or the Surviving Corporation, in obligations of or guaranteed by the United States of America or obligations of an agency of the United States of America which are backed by the full faith and credit of the United States of America (such cash amount being referred to herein as the "Exchange Fund"). Any interest and other income resulting from such investments shall be paid to Parent. To the extent that there are any losses with respect to any investments of the Exchange Fund, or the Exchange Fund diminishes for any reason below the level required for the Paying Agent to promptly pay the cash amounts contemplated by this Article II, Parent shall, or shall cause the Surviving Corporation to, promptly replace or restore the cash in the Exchange Fund so as to ensure that the Exchange Fund is at all times maintained at a level sufficient for the Paying Agent to make such payments contemplated by this Article II.

(c) Payment Procedures. Promptly following the Effective Time (and in any event within three Business Days), Parent and the Surviving Corporation shall cause the Paying Agent to mail (and The Depository Trust Company to deliver) to each holder of record (as of immediately prior to the Effective Time) of (i) a certificate or certificates (the "Certificates") which immediately prior to the Effective Time represented outstanding Company Shares and (ii) uncertificated Company Shares (the "Uncertificated Shares"), in each case, whose shares were converted into the right to receive the Per Share Merger Consideration pursuant to Section 2.7 (A) a letter of transmittal in customary form (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Paying Agent), and/or (B) instructions for use in effecting the surrender of the Certificates and Uncertificated Shares in exchange for the Per Share Merger Consideration payable in respect thereof pursuant to the provisions of this Article II. Upon

surrender of Certificates for cancellation to the Paying Agent or to such other agent or agents as may be appointed by Parent, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, the holders of such Certificates shall be entitled to receive in exchange therefor an amount in cash equal to the Per Share Merger Consideration to which the holder thereof is entitled pursuant to Section 2.7(a)(ii) (less any applicable withholding Taxes payable in respect thereof), and the Certificates so surrendered shall forthwith be canceled. Upon receipt of an "agent's message" by the Paying Agent (or such other evidence, if any, of transfer as the Paying Agent may reasonably request) in the case of a book-entry transfer of Uncertificated Shares, the holders of such Uncertificated Shares shall be entitled to receive in exchange therefor an amount in cash equal to the Per Share Merger Consideration to which the holder thereof is entitled pursuant to Section 2.7(a)(ii) (less any applicable withholding Taxes payable in respect thereof), and the transferred Uncertificated Shares so surrendered shall forthwith be canceled. The Paying Agent shall accept such Certificates and transferred Uncertificated Shares upon compliance with such reasonable terms and conditions as the Paying Agent may impose to effect an orderly exchange thereof in accordance with normal exchange practices. No interest shall be paid or accrued for the benefit of holders of the Certificates and Uncertificated Shares on the Per Share Merger Consideration payable upon the surrender of such Certificates and Uncertificated Shares pursuant to this Section 2.8. Until so surrendered, outstanding Certificates and Uncertificated Shares shall be deemed from and after the Effective Time, to evidence only the right to receive the Per Share Merger Consideration, without interest thereon, payable in respect thereof pursuant to the provisions of this Article II. Prior to the Effective Time, Parent and the Company shall establish procedures with the Paying Agent and the Depositary to ensure that (x) the Paying Agent will transmit to the Depositary promptly following the Effective Time an amount in cash in immediately available funds equal to the product of (1) the number of ADSs issued and outstanding immediately prior to the Effective Time and (2) the Per ADS Merger Consideration and (y) the Depositary will distribute the Per ADS Merger Consideration to ADS holders pro rata to their holdings of ADSs upon surrender by them of the ADSs. Pursuant to the Deposit Agreement, the ADS holders will pay any applicable fees, charges and expenses of the Depositary and government charges (other than withholding Taxes if any) due to or incurred by the Depositary in connection with distribution of the Per ADS Merger Consideration to ADS holders. No interest will be paid or accrued on any amount payable in respect of the ADSs.

(d) Transfers of Ownership. In the event that a transfer of ownership of Company Shares is not registered in the share transfer books or register of members of the Company, or if the Per Share Merger Consideration is to be paid in a name other than that in which the Certificates or Uncertificated Shares surrendered in exchange therefor are registered in the share transfer books or register of members of the Company, the Per Share Merger Consideration may be paid to a Person other than the Person in whose name the Certificate or Uncertificated Share so surrendered is registered in the share transfer books or register of members of the Company only if such Certificate or Uncertificated Shares is properly endorsed and otherwise in proper form for surrender and transfer and the Person requesting such payment has paid to Parent (or any agent designated by Parent) any transfer Taxes required by reason of the payment of the Per Share Merger Consideration to a Person other than the registered holder of such Certificate or Uncertificated Shares, or established to the satisfaction of Parent (or any agent designated by Parent) that such transfer Taxes have been paid or are otherwise not payable.

(e) Required Withholding. Each of the Paying Agent, Parent and the Surviving Corporation shall be entitled to deduct and withhold or cause to be deducted and withheld from any cash amounts payable pursuant to this Agreement such amounts as may be required to be deducted or withheld therefrom under applicable Tax Laws; provided that none of the Paying Agent, Parent or the Surviving Corporation will make or cause to be made any such deduction or withholding in respect of Taxes imposed under PRC Law or under the Code other than: (i) as required as a result of a change in relevant Law on or prior to the Closing Date; (ii) as required pursuant to a written notice by a

Governmental Authority; (iii) "backup" withholding Tax under the Code with respect to holders of Company Shares that do not provide a valid IRS Form W-8 or IRS Form W-9; or (iv) Taxes required to be deducted and withheld from amounts payable with respect to any Company Options. To the extent that such amounts are so deducted, withheld and remitted to the applicable Governmental Authority, such amounts shall be treated for all purposes under this Agreement as having been paid to the Person to whom such amounts would otherwise have been paid.

(f) No Liability. Notwithstanding anything to the contrary set forth in this Agreement, none of the Paying Agent, Depositary, Parent, the Surviving Corporation or any other party hereto shall be liable to a holder of Company Shares (including Company Shares represented by ADSs) or Company Options for any amount properly paid to a public official pursuant to any applicable abandoned property, escheat or similar Law.

(g) Distribution of Exchange Fund to Parent. Any portion of the Exchange Fund that remains undistributed to the holders of the Certificates, Uncertificated Shares or ADSs on the date that is twelve (12) months after the Effective Time shall be delivered to Parent upon demand, and any holders of Company Shares (other than Excluded Shares) or ADSs that were issued and outstanding immediately prior to the Merger who have not theretofore surrendered their Certificates, Uncertificated Shares or ADSs representing such Company Shares for exchange pursuant to the provisions of this Section 2.8 shall thereafter look for payment of the Per Share Merger Consideration or Per ADS Merger Consideration, as applicable, payable in respect of the Company Shares represented by such Certificates, Uncertificated Shares or ADSs solely to Parent, as general creditors thereof, for any claim to the applicable Per Share Merger Consideration or Per ADS Merger Consideration to which such holders may be entitled pursuant to the provisions of this Article II.

From and after the Effective Time, all Company Shares (including Company Shares represented by ADSs) shall no longer be outstanding, all Company Shares (including Company Shares represented by ADSs) shall automatically be cancelled, retired and cease to exist, and all ADSs shall be surrendered, and each holder of a Certificate, Uncertificated Shares or ADSs theretofore representing any Company Shares shall cease to have any rights with respect thereto, except the right to receive the Per Share Merger Consideration or the Per ADS Merger Consideration payable therefor upon the surrender thereof in accordance with the provisions of Section 2.8. The Per Share Merger Consideration and the Per ADS Merger Consideration paid in accordance with the terms of this Article II shall be deemed to have been paid in full satisfaction of all rights pertaining to such Company Shares (including Company Shares represented by ADSs). From and after the Effective Time, there shall be no further registration of transfers on the records of the Surviving Corporation of Company Shares (including Company Shares represented by ADSs) that were issued and outstanding immediately prior to the Effective Time, other than transfers to reflect, in accordance with customary settlement procedures, trades effected prior to the Effective Time. If, after the Effective Time, Certificates, Uncertificated Shares or ADSs are presented to the Surviving Corporation for any reason, they shall be canceled and exchanged as provided in this Article II.

Section 2.10 Lost, Stolen or Destroyed Certificates. In the event that any Certificates shall have been lost, stolen or destroyed, the Paying Agent shall issue in exchange for such lost, stolen or destroyed Certificates, upon the making of an affidavit of that fact by the holder thereof, the Per Share Merger Consideration payable in respect thereof pursuant to Section 2.7.

Section 3.6 Required Governmental Approvals. No consent, approval, Order or authorization of, or filing or registration with, or notification to (any of the foregoing being referred to herein as a "Consent"), any Governmental Authority is required on the part of the Company in connection with the execution and delivery by the Company of this Agreement, the performance by the Company of its covenants and obligations hereunder and the consummation by the Company of the transactions contemplated hereby, except (a) the filing and recordation of the Plan of Merger with the Registrar of Companies, (b) such filings and approvals as may be required by any federal or state securities laws, including compliance with any applicable requirements of the Exchange Act, including the joining of the Company in the filing of the Rule 13e-3 Transaction Statement on Schedule 13E-3 (including any amendments or supplements thereto, the "Schedule 13E-3") and the furnishing of Form 6-K with the Proxy Statement, and (c) such other Consents, the failure of which to obtain would not have a Company Material Adverse Effect or prevent or materially delay the consummation by the Company of the transactions contemplated hereby or the ability of the Company to perform its covenants and obligations hereunder.

(a) Parent and Merger Sub have delivered to the Company a complete and accurate copy of an executed equity commitment letter dated 21 February 2013 (the "Equity Commitment Letter") from the Guarantor pursuant to which the Guarantor has committed to provide, subject to the terms and conditions set forth therein, the cash amounts set forth therein to Parent to fully finance the Merger and the other transactions contemplated by this Agreement (the "Equity Financing"). The aggregate proceeds contemplated by the Equity Commitment Letter are sufficient to enable Parent to (i) consummate the Merger and the transactions contemplated herein upon the terms contemplated by this Agreement, (ii) pay all amounts that will become payable as a result of the consummation of the Merger and the transactions contemplated herein, including all amounts payable pursuant to Article II upon consummation of the Merger and the transactions contemplated herein on the Closing Date, and (iii) pay all related fees and expenses associated with the Merger and the transactions contemplated herein, incurred by Parent and Merger Sub or any of their respective Affiliates.

There are no conditions precedent or other contingencies related to the funding of the full amount of the Equity Financing, other than as set forth in the Equity Commitment Letter in the form so delivered to the Company. Parent and Merger Sub have no reason to believe that any term or condition to the Equity Financing set forth in the Equity Commitment Letter will not be fully satisfied on a timely basis or that the Equity Financing will not be available to Parent and Merger Sub at the Closing. Parent will have, as of the Closing Date, sufficient cash available to pay all amounts to be paid by Parent in connection with this Agreement. Parent's obligations hereunder are not subject to a condition regarding Parent's obtaining of funds to consummate the Transactions.

(c) Concurrently with the execution of this Agreement, Parent and Merger Sub are delivering to the Company the Guarantee of the Guarantor. The Guarantee is in full force and effect and is a valid and binding obligation of the Guarantor, enforceable against the Guarantor in accordance with its terms and no event has occurred which, with or without notice, lapse of time or both, could constitute a default on the part of the Guarantor under such Guarantee.

(d) Neither Parent nor Merger Sub, nor any of their respective Affiliates, is a party to or otherwise bound by any Contracts, or has any formal or informal arrangements or other understandings (whether or not binding, written or oral), with any Person (including any shareholder, director, officer or other employee of the Company or any of its Subsidiaries) concerning any investments to be made in or contributions to be made to Parent or Merger Sub in connection with the Merger and/or any other transactions contemplated by this Agreement other than as set forth in the Equity Commitment Letter.

(e) Neither Parent nor Merger Sub, nor any of their respective Affiliates, is a party to any Contracts, or has made or entered into any formal or informal arrangement or other understanding (whether or not binding, written or oral), with any other Person that has or would have the effect of requiring such Person to provide Parent or Merger Sub with financing or other potential sources of capital (whether equity, debtor a hybrid thereof) in any such case on an exclusive basis in connection with the Merger or any other transaction contemplated by this Agreement, or that has or would have the effect of preventing, impairing or otherwise limiting the ability of any Person to provide financing or other potential sources of capital (whether equity, debt or a hybrid thereof) to any other Person in connection with any transaction involving the Company.

Section 4.11 Shareholder and Management Arrangements. Except as expressly authorized by the Company in writing, neither Parent or Merger Sub, or any of their respective Affiliates, is a party to any Contracts, or has made or entered into any formal or informal arrangements or other understandings (whether or not binding), with any shareholder, director, officer or other Affiliate of the Company or any of its Subsidiaries relating to this Agreement, the Merger or any other transactions contemplated by this Agreement, or the Surviving Corporation or any of its Subsidiaries, businesses or operations (including as to continuing employment) from and after the Effective Time.

For purposes of the foregoing, "not have an unreasonably small amount of capital for the operation of the businesses in which it is engaged or proposed to be engaged" and "able to pay its liabilities, including contingent and other liabilities, as they mature" means that such Person will be able to generate enough cash from operations, asset dispositions or refinancing, or a combination thereof, to meet its obligations as they become due.

Accordingly, Parent and Merger Sub hereby acknowledge and agree that none of the Company or any of its Subsidiaries, nor any of their respective Affiliates, shareholders, directors, officers, employees, agents, representatives or advisors, nor any other Person, has made or is making any express or implied representation or warranty with respect to such estimates, projections, forecasts, forward-looking statements or business plans (including the reasonableness of the assumptions underlying such estimates, projections, forecasts, forward-looking statements or business plans).

Notwithstanding the foregoing, the Company shall not provide any commercially sensitive non-public information to any competitor in connection with the actions permitted by Section 5.2(b), except in a manner consistent with the Company's past practice in dealing with the disclosure of such information in the context of considering Acquisition Proposals prior to the date of this Agreement.

Notwithstanding the foregoing or anything to the contrary set forth in this Agreement, at any time prior to the Effective Time, the Company Board (acting through the Special Committee, if in existence) may effect a Company Board Recommendation Change if (i) the Company Board (acting through the Special Committee, if in existence) determines in good faith (after consultation with outside legal counsel) that the failure to effect a Company Board Recommendation Change would reasonably be expected to be inconsistent with its fiduciary duties to the Company Shareholders under applicable Law; (ii) the Company has notified Parent in writing that it intends to effect a Company Board Recommendation Change, describing in reasonable detail the reasons for such

Company Board Recommendation Change (a "Recommendation Change Notice") (it being agreed that the Recommendation Change Notice and any amendment or update to such notice and the determination to so deliver such notice, or update or amend public disclosures with respect thereto shall not constitute a Company Board Recommendation Change for purposes of this Agreement); and (iii) if requested by Parent, the Company shall have made its Representatives available to discuss with Parent's Representatives any proposed modifications to the terms and conditions of this Agreement during the period beginning at 5:00 p.m. Hong Kong Time on the day of delivery by the Company to Parent of such Recommendation Change Notice and ending three (3) Business Days later at 5:00 p.m. Hong Kong Time.

Any investigation conducted pursuant to the access contemplated by this Section 5.4 shall be conducted in a manner that does not unreasonably interfere with the conduct of the business of the Company and its Subsidiaries or create a risk of damage or destruction to any property or assets of the Company or any of its Subsidiaries. Any access to the Company's properties shall be subject to the Company's reasonable security measures and insurance requirements and shall not include the right to perform invasive testing.

In addition, during the period commencing at the Effective Time and ending on the sixth anniversary of the Effective Time, the Surviving Corporation and its Subsidiaries shall (and Parent shall cause the Surviving Corporation and its Subsidiaries to) cause the articles of association (and other similar organizational documents) of the Surviving Corporation and its Subsidiaries to contain provisions with respect to indemnification, exculpation and the advancement of expenses that are at least as favorable to the Indemnified Person as the indemnification, exculpation and advancement of expenses provisions contained in the articles of association (or other similar organizational documents) of the Company and its Subsidiaries as of the date hereof, and during such six-year period, such provisions shall not be repealed, amended or otherwise modified in any manner except as required by applicable Law.

(b) Without limiting the generality of the provisions of Section 6.1(a), during the period commencing at the Effective Time and ending on the sixth anniversary of the Effective Time, to the fullest extent permitted by applicable Law, the Surviving Corporation and its Subsidiaries shall (and Parent shall cause the Surviving Corporation and its Subsidiaries to) indemnify and hold harmless each Indemnified Person from and against any costs, fees and expenses (including reasonable attorneys' fees and investigation expenses), judgments, fines, losses, claims, damages, liabilities and amounts paid in settlement in connection with any claim, proceeding, investigation or inquiry, whether civil, criminal, administrative or investigative, to the extent such claim, proceeding, investigation or inquiry arises directly or indirectly out of or pertains directly or indirectly to (i) any action or omission or alleged action or omission in such Indemnified Person's capacity as a director, officer, employee or agent of the Company or any of its Subsidiaries or other Affiliates (regardless of whether such action or omission, or alleged action or omission, occurred prior to, at or after the Effective Time), or (ii) any of the transactions contemplated by this Agreement; provided that if, at any time prior to the sixth anniversary of the Effective Time, any Indemnified Person delivers to Parent a written notice asserting a claim for indemnification under this Section 6.1(b), then the claim asserted in such notice shall survive the sixth anniversary of the Effective Time until such time as such claim is fully and finally resolved. In addition, during the period commencing at the Effective Time and ending on the sixth anniversary of the Effective Time, to the fullest extent permitted by applicable Law, the Surviving Corporation and its Subsidiaries shall (and Parent shall cause the Surviving Corporation and its Subsidiaries to) advance, prior to the final disposition of any claim, proceeding, investigation or inquiry for which indemnification may be sought under this Agreement, promptly following request by an Indemnified Person therefor, all costs, fees and expenses (including reasonable attorneys' fees and investigation expenses) incurred by such Indemnified Person in connection with any such claim, proceeding, investigation or inquiry upon receipt of an undertaking by such Indemnified Person to repay such advances if it is ultimately decided in a final, non-appealable judgment by a court of competent jurisdiction that such Indemnified Person is not entitled to indemnification. In the event of any such claim, proceeding, investigation or inquiry, (A) the Surviving Corporation shall have the right to control the defense thereof after the Effective Time (it being understood that, by electing to control the defense thereof, the Surviving Corporation will be deemed to have waived any right to object to the Indemnified Person's entitlement to indemnification hereunder with respect thereto), (B) each Indemnified Person shall be entitled to retain his or her own counsel, whether or not the Surviving Corporation shall elect to control the defense of any such claim, proceeding, investigation or inquiry,

Notwithstanding anything to the contrary set forth in this Section 6.1(b) or elsewhere in this Agreement, neither the Surviving Corporation nor any of its Affiliates (including Parent) shall settle or otherwise compromise or consent to the entry of any judgment or otherwise seek termination with respect to any claim, proceeding, investigation or inquiry for which indemnification may be sought by an Indemnified Person under this Agreement unless such settlement, compromise, consent or termination includes an unconditional release of all Indemnified Persons from all liability arising out of such claim, proceeding, investigation or inquiry.

(c) During the period commencing at the Effective Time and ending on the sixth anniversary of the Effective Time, the Surviving Corporation shall (and Parent shall cause the Surviving Corporation to) maintain in effect the Company's current directors' and officers' liability insurance ("D&O Insurance") in respect of acts or omissions occurring at or prior to the Effective Time, covering each person covered by the D&O Insurance, on terms with respect to the coverage and amounts that are equivalent to those of the D&O Insurance; provided that in satisfying its obligations under this Section 6.1(c), Parent and the Surviving Corporation shall not be obligated to pay annual premiums in excess of three hundred percent (300%) of the amount paid by the Company for coverage for its last full fiscal year (such three hundred percent (300%) amount, the "Maximum Annual Premium"); provided further that, if the annual premiums of such insurance coverage exceed such amount, Parent and the Surviving Corporation shall be obligated to obtain a policy with the greatest coverage available for a cost not exceeding the Maximum Annual Premium. Prior to the Effective Time, notwithstanding anything to the contrary set forth in this Agreement, the Company may purchase a six-year "tail" prepaid policy on the D&O Insurance. In the event that the Company elects to purchase such a "tail" policy prior to the Effective Time, the Surviving Corporation shall (and Parent shall cause the Surviving Corporation to) maintain such "tail" policy in full force and effect and continue to honor their respective obligations thereunder, in lieu of all other obligations of Parent and the Surviving Corporation under the first sentence of this Section 6.1(c) for so long as such "tail" policy shall be maintained in full force and effect.

(d) If Parent or the Surviving Corporation or any of their successors or assigns shall (i) consolidate with or merge into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger, or (ii) transfer all or substantially all of its properties and assets to any Person, then, and in each such case, proper provisions shall be made so that the successors and assigns of the Surviving Corporation shall assume all of the obligations of Parent and the Surviving Corporation set forth in this Section 6.1.

(e) The obligations set forth in this Section 6.1 shall not be terminated, amended or otherwise modified in any manner that adversely affects any Indemnified Person (or any other person who is a beneficiary under the D&O Insurance or the "tail" policy referred to in Section 6.1(c) (and their heirs and representatives)) without the prior written consent of such affected Indemnified Person or other person who is a beneficiary under the D&O Insurance or the "tail" policy referred to in Section 6.1(c) (and their heirs and representatives). Each of the Indemnified Persons or other persons who are beneficiaries under the D&O Insurance or the "tail" policy referred to in Section 6.1(c) (and their heirs and representatives) are intended to be third party beneficiaries of this Section 6.1, with full rights of enforcement as if a party thereto. The rights of the Indemnified Persons (and other persons who are beneficiaries under the D&O Insurance or the "tail" policy referred to in Section 6.1(c) (and their heirs and representatives)) under this Section 6.1 shall be in addition to, and not in substitution for, any other rights that such persons may have under the certificates of incorporation, bylaws or other equivalent organizational documents, any and all indemnification agreements of or entered into by the Company or any of its Subsidiaries, or applicable Law (whether at law or in equity).

(f) The obligations and liability of Parent, the Surviving Corporation and their respective Subsidiaries under this Section 6.1 shall be joint and several.

Prior to the Closing, none of Parent, Merger Sub or any of its Affiliates shall take any action to cause or induce any Person (including the Guarantor) to take any action that, if taken by Parent, Merger Sub or any of its Affiliates, would be a breach of this Section 6.3(c).

Notwithstanding anything to the contrary herein, the Company shall not be required prior to the Effective Time to pay any consent or other similar fee,

"profit sharing" or other similar payment or other consideration (including increased rent or other similar payments or any amendments, supplements or other modifications to (or waivers of) the existing terms of any Contract), or the provision of additional security (including a guaranty) to obtain the consent, waiver or approval of any Person under any Contract.

The Special Committee of the Board of Directors
WSP Holdings Limited
No. 38 Zhujiang Road
Xinqu, Wuxi
Jiangsu Province
People's Republic of China

We understand that WSP Holdings Limited ("WSP Holdings"), WSP OCTG GROUP Ltd. ("Parent"), a wholly owned subsidiary of H.D.S. Investments LLC ("HDS"), and JM OCTG GROUP Ltd., a wholly owned subsidiary of Parent ("Merger Sub"), propose to enter into a Merger Agreement (as defined below) pursuant to which, among other things, Merger Sub will be merged with and into WSP Holdings (the "Merger") and (i) each outstanding ordinary share, par value US$0.0001 per share, of WSP Holdings ("WSP Ordinary Shares"), other than WSP Ordinary Shares beneficially owned by Rollover Holders (as defined below), Parent, Merger Sub, WSP Holdings (as treasury shares, if any) or any of their respective subsidiaries and holders who have validly exercised and not withdrawn their appraisal rights with respect to their WSP Ordinary Shares, will be converted into the right to receive US$0.32 in cash (the "Per Share Consideration") and (ii) each American Depository Share, representing 10 WSP Ordinary Shares ("WSP ADSs" and, together with WSP Ordinary Shares, "WSP Shares"), will be converted into the right to receive US$3.20 in cash (the "Per ADS Consideration" and, together with the Per Share Consideration, the "Consideration"). As more fully described in the Merger Agreement, Mr. Longhua Piao, chairman of the Board of Directors, chief executive officer and majority shareholder of WSP Holdings, Expert Master Holdings Limited, a wholly owned subsidiary of Mr. Piao ("EMHL"), and UMW China Ventures (L) Ltd., a significant shareholder of WSP Holdings ("UMW"), will enter into rollover, voting and other agreements with Parent and Merger Sub (Mr. Piao, EMHL and UMW, collectively with any other holder of WSP Shares who enters into similar arrangements with Parent or its affiliates, "Rollover Holders").

The Special Committee of the Board of Directors (the "Board" and, such special committee, the "Special Committee") of WSP Holdings has requested that Houlihan Lokey (China) Limited ("Houlihan Lokey") provide an opinion (the "Opinion") to the Special Committee as to whether, as of the date hereof, the Per Share Consideration to be received in the Merger pursuant to the Merger Agreement by holders of WSP Ordinary Shares and the Per ADS Consideration to be received in the Merger pursuant to the Merger Agreement by holders of WSP ADSs (in each case other than Parent, Merger Sub, Rollover Holders and their respective affiliates) are fair to such holders from a financial point of view.

In connection with this Opinion, we have made such reviews, analyses and inquiries as we have deemed necessary and appropriate under the circumstances. Among other things, we have:

We have relied upon and assumed, without independent verification, the accuracy and completeness of all data, material and other information furnished, or otherwise made available, to us, discussed with or reviewed by us, or publicly available, and do not assume any responsibility with respect to such data, material and other information. As the Special Committee is aware, we have been advised by the management of WSP Holdings that the only long-term projections for WSP Holdings are those prepared and provided to us by such management in February 2012, that certain changes have occurred in WSP Holdings' business and operations since February 2012 and that the actual performance of WSP Holdings for the fiscal year ended December 31, 2012 was materially less favorable than as reflected in such long-term projections. As the Special Committee also is aware, it is our understanding that WSP Holdings and its subsidiaries have been in breach of certain financial

covenants under certain loan agreements and that the consolidated financial statements of WSP Holdings for the fiscal year ended December 31, 2011 included an explanatory paragraph indicating that there is a going concern uncertainty for WSP Holdings, which could adversely affect the ability of WSP Holdings to meet its ongoing financing needs and obtain third-party financing. Notwithstanding the foregoing, management of WSP Holdings has advised us, and we have assumed, at the direction of the Special Committee, that the financial projections and other estimates (and adjustments thereto) utilized in our analyses have been reasonably prepared in good faith on bases reflecting the best available estimates and judgments of such management as to the future financial results and condition of WSP Holdings under an optimistic scenario. We express no opinion with respect to such projections and estimates or the assumptions on which they are based.

We have relied upon and assumed, without independent verification, that there has been no change in the business, assets, liabilities, financial condition, results of operations, cash flows or prospects of WSP Holdings since the respective dates of the most recent financial statements and other information, financial or otherwise, provided to us that would be material to our analyses or this Opinion, and that there is no information or any facts that would make any of the information reviewed by us incomplete or misleading. In addition, we understand that financial projections for WSP Holdings have been prepared by the management of WSP Holdings in Renminbi ("RMB"), the legal currency of China. We have utilized certain publicly available RMB to United States dollar exchange rates and we have assumed, with the consent of the Special Committee, that such exchange rates are reasonable to utilize for purposes of our analyses. We express no view or opinion as to any currency or exchange rate fluctuations and have assumed, with the consent of the Special Committee, that any such fluctuations will not in any respect be material to our analyses or this Opinion. We have relied, at the direction of the Special Committee, upon the assessments of the management of WSP Holdings as to, among other things, (i) macroeconomic conditions and governmental and regulatory matters affecting WSP Holdings, (ii) the amount of restricted cash currently available for the operations of WSP Holdings and the continued availability of such cash for its operations and (iii) cyclical and market trends and prospects for the oil and gas industry, including assumptions of the management of WSP Holdings as to future oil, gas and related commodity prices, which are subject to significant volatility and which, if different than as assumed, could impact our analyses or this Opinion. We have assumed, with the consent of the Special Committee, that there will be no developments with respect to any such matters that would affect our analyses or this Opinion. In addition, the management of WSP Holdings has advised us, and we have assumed, at the direction of the Special Committee, that each WSP ADS represents, and is equivalent for purposes of our analyses and this Opinion to, 10 WSP Ordinary Shares.

We have relied upon and assumed, without independent verification, that (a) the representations and warranties of all parties to the Merger Agreement and all other related documents and instruments that are referred to therein are true and correct, (b) each party to the Merger Agreement and such other related documents and instruments will fully and timely perform all of the covenants and agreements required to be performed by such party, (c) all conditions to the consummation of the Merger will be satisfied without waiver thereof, and (d) the Merger will be consummated in a timely manner in accordance with the terms described in the Merger Agreement and such other related documents and instruments, without any amendments or modifications thereto. We also have relied upon and assumed, without independent verification, that (i) the Merger will be consummated in a manner that complies in all respects with all applicable international, federal and state statutes, rules and regulations, and (ii) all governmental, regulatory, and other consents and approvals necessary for

the consummation of the Merger will be obtained and no delay, limitations, restrictions or conditions will be imposed or amendments, modifications or waivers made that would have an effect on WSP Holdings or the Merger that would be material to our analyses or this Opinion. In addition, we have relied upon and assumed, without independent verification, that the final executed Merger Agreement will not differ in any respect from the execution version of the Merger Agreement identified above.

Furthermore, in connection with this Opinion, we have not been requested to make, and have not made, any physical inspection or independent appraisal or evaluation of any of the assets, properties or liabilities (fixed, contingent, derivative, off-balance sheet or otherwise) of WSP Holdings or any other party or entity, nor were we provided with any such appraisal or evaluation. We did not estimate, and express no opinion regarding, the liquidation value of WSP Holdings or any other entity or business. We have undertaken no independent analysis of any potential or actual litigation, regulatory action, possible unasserted claims or other contingent liabilities to which WSP Holdings is or may be a party or is or may be subject, or of any governmental investigation of any possible unasserted claims or other contingent liabilities to which WSP Holdings is or may be a party or is or may be subject.

We have not been requested to, and did not, (a) initiate any discussions with, or solicit any indications of interest from, third parties with respect to the Merger, the securities, assets, businesses or operations of WSP Holdings or any other party or entity, or any alternatives to the Merger or (b) advise the Special Committee, the Board or any other party or entity with respect to alternatives to the Merger. This Opinion is necessarily based on financial, economic, market and other conditions as in effect on, and the information made available to us as of, the date hereof. We have not undertaken, and are under no obligation, to update, revise, reaffirm or withdraw this Opinion, or otherwise comment on or consider events occurring or coming to our attention after the date hereof. This Opinion does not purport to address potential developments in the credit, financial or stock markets, including, without limitation, the market for WSP ADSs. We also are not expressing any opinion as to the price or range of prices at which WSP ADSs will trade, or WSP Ordinary Shares may be transferable, at any time. In addition, we express no view as to, and we have not assessed or considered, foreign currency exchange risks associated with the Merger or otherwise.

This Opinion is furnished for the use of the Special Committee (in its capacity as such) in connection with its evaluation of the Merger and may not be used for any other purpose without our prior written consent. This Opinion should not be construed as creating any fiduciary duty on Houlihan Lokey's part to any party or entity. This Opinion is not intended to be, and does not constitute, a recommendation to the Special Committee, the Board, any security holder or any other party or entity as to how to act or vote with respect to any matter relating to the Merger or otherwise.

In the ordinary course of business, certain of our employees and affiliates, as well as investment funds in which they may have financial interests or with which they may co-invest, may acquire, hold or sell, long or short positions, or trade, in debt, equity, and other securities and financial instruments (including loans and other obligations) of, or investments in, WSP Holdings, HDS, EMHL, UMW or any other party that may be involved in the Merger and their respective affiliates or any currency or commodity that may be involved in the Merger.

Houlihan Lokey and certain of its affiliates in the future may provide investment banking, financial advisory and other financial services to WSP Holdings, HDS, EMHL, UMW, other participants in the Merger and their respective affiliates, and one or more security holders or portfolio companies of such entities, for which Houlihan Lokey and such affiliates may receive compensation. In addition, Houlihan

Lokey and certain of its affiliates and certain of our and their respective employees may have committed to invest in private equity or other investment funds managed or advised by HDS, EMHL, UMW or other participants in the Merger or certain of their respective affiliates or security holders, and in portfolio companies of such funds, and may have co-invested with such funds, HDS, EMHL, UMW or other participants in the Merger or certain of their respective affiliates or security holders, and may do so in the future. Furthermore, in connection with bankruptcies, restructurings, and similar matters, Houlihan Lokey and certain of its affiliates in the past may have acted, currently may be acting and in the future may act as financial advisor to debtors, creditors, equity holders, trustees and other interested parties (including, without limitation, formal and informal committees or groups of creditors) that may have included or represented and may include or represent, directly or indirectly, or may be or have been adverse to, WSP Holdings, HDS, EMHL, UMW, other participants in the Merger and/or their respective affiliates, and/or one or more security holders or portfolio companies of such entities, for which advice and services Houlihan Lokey and such affiliates have received and may receive compensation.

Houlihan Lokey has been engaged as financial advisor to the Special Committee in connection with the Merger and has received and will receive a fee for such services, a portion of which is contingent upon consummation of the Merger. In addition, we will receive a fee for rendering this Opinion, which is not contingent upon the successful completion of the Merger or the conclusion contained in this Opinion. In addition, WSP Holdings has agreed to reimburse certain of our expenses and to indemnify us and certain related parties for certain potential liabilities arising out of our engagement.

Our Opinion relates to the fairness, from a financial point of view, of the Per Share Consideration to be received in the Merger pursuant to the Merger Agreement by holders of WSP Ordinary Shares and the Per ADS Consideration to be received in the Merger pursuant to the Merger Agreement by holders of WSP ADSs (in each case other than Parent, Merger Sub, Rollover Holders and their respective affiliates), without regard to any rights, restrictions or limitations that may be attributable to WSP Ordinary Shares or WSP ADSs, including, without limitation, conversion or other features, redemption fees or related expenses. We have not been requested to opine as to, and this Opinion does not express an opinion as to or otherwise address, among other things: (i) the underlying business decision of the Special Committee, the Board, WSP Holdings, its security holders or any other party or entity to proceed with or effect the Merger, (ii) the terms of any arrangements, understandings, agreements or documents related to, or the form, structure or any other portion or aspect of, the Merger (other than the Consideration to the extent expressly specified herein) or otherwise, including, without limitation, any terms or aspects of any rollover, voting or other agreements to be entered into in connection with the Merger, any potential financing for the Merger or the likelihood of consummation thereof, (iii) the fairness of any portion or aspect of the Merger to the holders of any class of securities, creditors or other constituencies of WSP Holdings, or to any other party or entity, except if and only to the extent expressly set forth in the last paragraph of this Opinion, (iv) the relative merits of the Merger as compared to any alternative business strategies or transactions that might be available for WSP Holdings or any other party, (v) the fairness of any portion or aspect of the Merger to any one class or group of WSP Holdings' or any other party's security holders or other constituents vis-à-vis any other class or group of WSP Holdings' or such other party's security holders or other constituents (including, without limitation, the allocation of any consideration amongst or within such classes or groups of security holders or other constituents), (vi) whether or not WSP Holdings, its security holders or any other party is receiving or paying reasonably equivalent value

in the Merger, (vii) the solvency, creditworthiness or fair value of WSP Holdings or any other participant in the Merger, or any of their respective assets, under any applicable laws relating to bankruptcy, insolvency, fraudulent conveyance or similar matters, or (viii) the fairness, financial or otherwise, of the amount, nature or any other aspect of any compensation to or consideration payable to or received by any officers, directors or employees of any party to the Merger, any class of such persons or any other party, relative to the Consideration or otherwise. Furthermore, no opinion, counsel or interpretation is intended in matters that require legal, regulatory, accounting, insurance, tax or other similar professional advice. It is assumed that such opinions, counsel or interpretations have been or will be obtained from appropriate professional sources. Furthermore, we have relied, with the consent of the Special Committee, on the assessments by the Special Committee, the Board, WSP Holdings and their respective advisors as to all legal, regulatory, accounting, insurance and tax matters with respect to WSP Holdings, the Merger or otherwise. The issuance of this Opinion was approved by a committee authorized to approve opinions of this nature.

Based upon and subject to the foregoing, and in reliance thereon, it is our opinion that, as of the date hereof, the Per Share Consideration to be received in the Merger pursuant to the Merger Agreement by holders of WSP Ordinary Shares and the Per ADS Consideration to be received in the Merger pursuant to the Merger Agreement by holders of WSP ADSs (in each case other than Parent, Merger Sub, Rollover Holders and their respective affiliates) are fair to such holders from a financial point of view.

Capitalized terms used but not defined herein shall have the meanings ascribed to such terms in the Merger Agreement (defined below).

WHEREAS, Parent and Merger Sub have entered into an Agreement and Plan of Merger, dated as of the date hereof (as may be amended, supplemented or otherwise modified from time to time, the "Merger Agreement"), by and among Parent, Merger Sub and the Company, pursuant to which Merger Sub will merge with and into the Company on the terms and subject to the conditions set forth in the Merger Agreement and the Company shall remain as the Surviving Corporation;

WHEREAS, as a result of the Merger, the Company shall succeed to and assume all the rights and obligations of Merger Sub in accordance with the Merger, including the obligations of Merger Sub set forth in this Agreement, and references in this Agreement to Merger Sub encompass the Surviving Corporation after the Merger;

WHEREAS, each Rollover Shareholder desires to contribute the number of Company Shares shown on Schedule 1 hereto opposite its name (the "Rollover Shares") to Parent immediately prior to the Effective Time, in exchange for the number of common shares of Parent shown on Schedule 1 hereto opposite its name (the "Parent Issued Securities").

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements herein contained and intending to be legally bound hereby, the parties hereto hereby agree as follows:

"Rollover Effective Time" means the time immediately prior to the Effective Time.

"SAFE Circulars" means the Notice Regarding Certain Administrative Measures on Financing and Inbound Investments by PRC Residents Through Offshore Special Purpose Vehicles promulgated by SAFE and effective on November 1, 2005 and the Operating Instructions on Foreign Exchange Administration for Domestic Residents Engaging in Financing and Round-tripping Investment via Overseas Special Purpose Vehicles promulgated by SAFE and effective on July 1, 2011.

2. Contribution of Rollover Shares. At the Rollover Effective Time, each Rollover Shareholder shall contribute the Rollover Shares held by it to the capital of Parent and Parent shall accept as a contribution the Rollover Shares. In exchange for the Rollover Shares, Parent shall issue to each

Rollover Shareholder a pro rata (in kind and amount) portion of the share capital of Parent (based on the number of Rollover Shares contributed by each Rollover Shareholder) (the "Parent Issued Securities") at the same price per share as is paid by the other shareholders of Parent (excluding related fees and expenses) in connection with the Closing (the "Per Share Price"), assuming that the price per share paid in respect of each Rollover Share is equal to the Merger Consideration payable in respect of one Company Share under the Merger Agreement. The number of Rollover Shares to be contributed by and of Parent Issued Securities to be issued to each Rollover Shareholder in accordance with this Section 2 is set forth next to such Rollover Shareholder's name on Schedule 1 hereto.

3. Equity Interests Other Than Rollover Shares.

4. Conditions. (a) The consummation of the contribution by each Rollover Shareholder of the Rollover Shares pursuant to Section 2 hereof shall be subject to the satisfaction or (in the case of clauses (i), (ii) and (iii)) waiver by such Rollover Shareholder of the following conditions: (i) the delivery to such Rollover Shareholder by Parent of a copy of the Shareholders Agreement duly executed by Parent; (ii) that the representations and warranties of Parent contained in this Agreement shall be true and correct in all material respects as of the Closing Date; (iii) that Parent shall have performed or complied with in all material respects all covenants required to be performed or complied with by it under this Agreement; (iv) the issuance of the Parent Issued Securities to which such Rollover Shareholder is entitled under Section 2 concurrently with such contribution; and (v) the consummation of the Merger immediately following such contribution.

(d) Time of the Essence. Time is of the essence for each and every provision of this Agreement. Whenever the last day for the exercise of any privilege or the discharge or any duty hereunder shall fall upon any day that is not a Business Day, the party having such privilege or duty may exercise such privilege or discharge such duty on the next succeeding day which is a regular Business Day.

(e) Further Assurances. From time to time following the date hereof, the parties hereto shall execute and deliver such other instruments of assignment, transfer and delivery (including the delivery by each Rollover Shareholder to Parent or Merger Sub of certificates representing the Rollover Shares) and shall take such other actions as any other party hereto reasonably may request in order to consummate, complete and carry out the transactions contemplated by this Agreement.

(f) Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to either party hereto. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, Parent and the Rollover Shareholder shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties hereto as closely as possible in an acceptable manner to the end that transactions contemplated hereby are fulfilled to the greatest extent possible.

(g) Entire Agreement. This Agreement, the Merger Agreement and the Voting Agreements embody the complete agreement and understanding among the parties hereto with respect to the subject matter hereof and supersede and preempt any prior understandings, agreements or representations by or among the parties, written or oral, which may have related to the subject matter hereof in any way.

(h) Specific Performance. The parties hereto shall be entitled to enforce their rights under this Agreement specifically, to recover damages and costs (including reasonable attorneys' fees) caused by any breach of any provision of this Agreement and to exercise all other rights existing in their favor. Each party hereto agrees and acknowledges that money damages may not be an adequate remedy for any breach of the provisions of this Agreement and that, in addition to any other rights and remedies at law or in equity existing in its favor, each party hereto shall be entitled to specific performance and/or other injunctive relief from any court of law or equity of competent jurisdiction (without posting any bond or other security) in order to enforce or prevent violation of the provisions of this Agreement.

(i) Amendment and Waiver. Except as otherwise provided herein, the provisions of this Agreement may be amended or waived only upon the prior written consent of Parent and each Rollover Shareholder. The failure of any party to enforce any of the provisions of this Agreement shall in no way be construed as a waiver of such provisions and shall not affect the right of such party thereafter to enforce each and every provision of this Agreement in accordance with its terms.

(j) Delivery by Facsimile and Electronically. This Agreement and any signed agreement or instrument entered into in connection thereto or contemplated thereby, and any amendments hereto or thereto, to the extent signed and delivered by means of a facsimile machine or email, shall be treated in all manner and respects as an original agreement or instrument and shall be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person. At the request of any party hereto or to any such agreement or instrument, each other party hereto or thereto shall re execute original forms thereof and deliver them to all other parties. No party hereto or to any such agreement or instrument shall raise the use of a facsimile machine or email to deliver a signature or the fact that any signature or agreement or instrument was transmitted or communicated through the use of a facsimile machine or email as a defense to the formation of a contract and each such party forever waives any such defense.

(k) Applicable Law; Dispute Resolution. This Agreement, and all claims and causes of action arising out of, based upon, or related to this Agreement or the negotiation, execution or performance

hereof, shall be governed by, and construed, interpreted and enforced in accordance with, the Laws of the State of Delaware, without regard to choice or conflict of law principles that would result in the application of any Laws other than the Laws of the State of Delaware. In the event any dispute arises among the parties hereto out of or in relation to this Agreement, including any dispute regarding its breach, termination or validity, the parties shall attempt in the first instance to resolve such dispute through friendly consultations. If any dispute has not been resolved by friendly consultations within thirty (30) days after any party has served written notice on the other parties requesting the commencement of such consultations, then any party may demand that the dispute be finally settled by arbitration in accordance with the following provisions of this Section 12(k). The arbitration shall be conducted in accordance with the UNCITRAL Arbitration Rules and the Hong Kong International Arbitration Centre ("HKIAC") Procedures for the Administration of International Arbitration in force at the date of this Agreement, which rules are deemed to be incorporated by reference in this Section 12(k). The place of the arbitration shall be Hong Kong and the language of the arbitration shall be English. The appointing authority shall be the HKIAC. There shall be three arbitrators, which shall be designated as set forth in Section 10.9 of the Merger Agreement. The arbitration shall be conducted in private. The parties agree that all documents and evidence submitted in the arbitration (including without limitation any statements of case and any interim or final award, as well as the fact that an arbitral award has been made) shall remain confidential both during and after any final award that is rendered unless the parties hereto otherwise agree in writing. Upon and after the submission of any dispute to arbitration, the parties shall continue to exercise their remaining respective rights, and fulfill their remaining respective obligations under this Agreement, except insofar as the same may relate directly to the matters in dispute. The parties hereby agree that any arbitration award rendered in accordance with the provisions of this Section 12(k) shall be final and binding upon them, and the parties further agree that such award may be enforced by any court having jurisdiction over the party against which the award has been rendered or the assets of such party wherever the same may be located. In any arbitration proceeding, any legal proceeding to enforce any arbitration award and in any other legal proceeding among the parties pursuant to or relating to this Agreement, each party expressly waives the defense of sovereign immunity and any other defense based on the fact or allegation that it is an agency or instrumentality of a sovereign state or is otherwise entitled to immunity. Each of the parties hereto agrees that notice or the service of process in any action, suit or proceeding arising out of, based upon or relating to this Agreement or the rights and obligations arising hereunder shall be properly served or delivered if delivered in the manner contemplated by Section 12(a) of this Agreement.

The representations and warranties set forth herein and the covenants set forth herein have been made solely for the benefit of the parties to this Agreement and (a) may be intended not as statements of fact, but rather as a way of allocating the risk to one of the parties if those statements prove to be inaccurate and (b) may apply standards of materiality in a way that is different from what may be viewed as material by shareholders of, or other investors in, the Company.

Section 6.7 Specific Performance.

The Shareholder agrees not to oppose the granting of such relief in the event a court determines that such a breach has occurred, and to waive any requirement for the securing or posting of any bond in connection with such remedy. All rights, powers, and remedies provided under this Agreement or otherwise available in respect hereof at law or in equity shall be cumulative and not alternative, and the exercise or beginning of the exercise of any thereof by Parent, Merger Sub or the Company shall not preclude the simultaneous or later exercise of any other such right, power or remedy by such party.

Section 6.10 Consent to Jurisdiction. In the event any dispute arises among the parties hereto out of or in relation to this Agreement, including any dispute regarding its breach, termination or validity, the parties shall attempt in the first instance to resolve such dispute through friendly consultations. If any dispute has not been resolved by friendly consultations within thirty (30) days after any party has served written notice on the other parties requesting the commencement of such consultations, then any party may demand that the dispute be finally settled by arbitration in accordance with the following provisions of this Section 6.10. The arbitration shall be conducted in accordance with the UNCITRAL Arbitration Rules and the Hong Kong International Arbitration Centre ("HKIAC") Procedures for the Administration of International Arbitration in force at the date of this Agreement, which rules are deemed to be incorporated by reference in this Section 6.10. The place of the arbitration shall be Hong Kong and the language of the arbitration shall be English. The appointing authority shall be the HKIAC. There shall be three arbitrators. One arbitrator shall be nominated by the Company or the Parent, as applicable, and one arbitrator shall be nominated by the Shareholder. If any party shall abstain from nominating their arbitrator, the HKIAC shall appoint such arbitrator. The two arbitrators so chosen shall select a third arbitrator; provided that if such two arbitrators shall fail to choose a third arbitrator within 30 days after such two arbitrators have been selected, the HKIAC, upon the request of any party, shall appoint a third arbitrator. The third arbitrator shall be the presiding arbitrator. The arbitration shall be conducted in private. The parties agree that all documents and evidence submitted in the arbitration (including without limitation any statements of case and any interim or final award, as well as the fact that an arbitral award has been made) shall remain confidential both during and after any final award that is rendered unless the parties hereto otherwise agree in writing. Upon and after the submission of any dispute to arbitration, the parties shall continue to exercise their remaining respective rights, and fulfill their remaining respective obligations under this Agreement, except insofar as the same may relate directly to the matters in dispute. The parties hereby agree that any arbitration award rendered in accordance with the provisions of this Section 6.10 shall be final and binding upon them, and the parties further agree that such award may be enforced by any court having jurisdiction over the party against which the award has been rendered or the assets of such party wherever the same may be located. In any arbitration proceeding, any legal proceeding to enforce any arbitration award and in any other legal proceeding among the parties pursuant to or relating to this Agreement, each party expressly waives the defense of sovereign immunity and any other defense based on the fact or allegation that it is an agency or instrumentality of a sovereign state or is otherwise entitled to immunity.
