Section 2.01 Effect of Merger on Issued Securities.

At the Effective Date, by virtue of the Merger and without any action on the part of Parent, Merger Sub, the Company or the holders of any securities of the Company:

(a) each Share issued and outstanding immediately prior to the Effective Date (other than the Continuing Shares, the Excluded Shares, the Dissenting Shares and Shares represented by ADSs (each as defined below)) shall cease to exist and shall be cancelled in consideration for the right to receive an amount in cash per Share and without interest, equal to $0.03125 (the “Per Share Merger Consideration”), which shall be payable in the manner provided in Section 2.04;

(b) each American Depositary Share, representing twelve Shares (an “ADS”), issued and outstanding immediately prior to the Effective Date (other than, if any, ADSs representing the Excluded Shares), shall cease to exist and shall be cancelled in exchange for an amount in cash per ADS and without interest, equal to $0.375 (the “Per ADS Merger Consideration”) (less up to

3

$0.05 per ADS cancellation fees), payable pursuant to the terms and conditions set forth in the Deposit Agreement, and each Share represented by such ADSs shall be cancelled and cease to exist, in exchange for the right of the Depositary, as the registered holder thereof, to receive the Per Share Merger Consideration, which the Depositary will distribute to the holders of such ADSs as the Per ADS Merger Consideration pursuant to the terms and conditions set forth in this Agreement and the Deposit Agreement (less up to $0.05 per ADS cancellation fees);

(c) no holder of Continuing Shares shall have the right to receive the Per Share Merger Consideration or the Per ADS Merger Consideration in respect of the Continuing Shares, and instead, each Continuing Share issued and outstanding immediately prior to the Effective Date shall continue to exist without interruption and shall thereafter be and represent one validly issued, fully paid and non-assessable ordinary share, par value $0.0003 each, of the Surviving Company;

(d) each of the Excluded Shares and ADSs representing the Excluded Shares (in each case, issued and outstanding immediately prior to the Effective Date) shall be cancelled and shall cease to exist without payment of any consideration or distribution therefor;

(e) each of the Dissenting Shares shall be cancelled and thereafter afford the holder only the rights referred to at Section 2.03;

(f) each ordinary share, par value $0.0003 each, of Merger Sub issued and outstanding immediately prior to the Effective Date shall be converted into one validly issued, fully paid and non-assessable ordinary share, par value $0.0003 each, of the Surviving Company; such ordinary shares of the Surviving Company shall (other than as set forth in the memorandum and articles of association of the Surviving Company) rank pari passu in all respects with the Continuing Shares which shall continue and survive the Merger in accordance with Section 2.01(c), and such ordinary shares, including the Continuing Shares, shall constitute the only issued and outstanding share capital of the Surviving Company, which shall be reflected in the register of members of the Surviving Company; and

(g) each Company Warrant outstanding immediately prior to the Effective Date shall be treated in accordance with the terms thereof, as may be amended prior to the Effective Date by the Company and the holder thereof with the consent of Parent. The Surviving Corporation, and to the extent required under the applicable Company Warrant, Parent, shall comply with any obligations under the applicable Company Warrant.

Section 2.02 Share Incentive Plans and Outstanding Company Share Awards.

(a) As soon as reasonably practicable following the date hereof, the Company, acting through the Company Board or the renumeration committee of the Company Board, as applicable, or otherwise, shall adopt any resolutions and take any actions that are reasonably necessary to (i) terminate the Share Incentive Plans and any relevant award agreements applicable to the Share Incentive Plans or any Company Share Award, as of the Effective Date, (ii) cancel each Company Share Award that is outstanding and unexercised, whether or not vested or exercisable, as of the Effective Date and (iii) otherwise effectuate the provisions of this Section 2.02. From and after the Effective Date, neither the Buyer Group nor the Surviving Company shall be

4

required to issue any Shares, other share capital of the Company or the Surviving Company, share capital of any Buyer Group Party or any other consideration (other than as required by this Section 2.02) to any person pursuant to or in settlement of any Company Share Award. Following the adoption of such resolutions and the taking of such other actions as reasonably necessary to achieve the foregoing by the Company Board or the renumeration committee of the Company Board, the Company shall deliver written notice to each holder of a Company Share Award informing such holder of the effect of the Merger on its Company Share Awards.

(b) Except as otherwise set forth in Section 2.02(b) of the Company Disclosure Schedule, each former holder of a Vested Company Option that is cancelled at the Effective Date shall, in exchange therefor, be paid by the Surviving Company or one of its Subsidiaries, as soon as practicable after the Effective Date (without interest), a cash amount equal to the product of (i) the excess, if any, of the Per Share Merger Consideration over the Exercise Price of such Vested Company Option and (ii) the number of Shares underlying such Company Option; provided, that if the Exercise Price of any such Company Option is equal to or greater than the Per Share Merger Consideration, such Company Option shall be cancelled without any payment therefor.

(c) Each former holder of an Unvested Company Option that is cancelled at the Effective Date shall, in exchange therefor, receive as soon as practicable after the Effective Date, a restricted cash award (“RCA”) issued by the Surviving Company in an amount in cash that is the equivalent of, the product of (i) the excess, if any, of the Per Share Merger Consideration over the Exercise Price of such Unvested Company Option and (ii) the number of Shares underlying such Unvested Company Option; provided, that if the Exercise Price of any such Unvested Company Option is equal to or greater than the Per Share Merger Consideration, such Unvested Company Option shall be cancelled without any payment therefor.

(d) Each former holder of a Vested Company RSU that is cancelled at the Effective Date shall, in exchange therefor, be paid by the Surviving Company or one of its Subsidiaries, as soon as practicable after the Effective Date (without interest), a cash amount equal to the product of (i) the Per ADS Merger Consideration and (ii) the number of ADSs underlying such Company RSU.

(e) Each former holder of an Unvested Company RSU that is cancelled at the Effective Date shall, in exchange therefor, receive as soon as practicable after the Effective Date, a RCA issued by the Surviving Company in an amount in cash that is the equivalent of, the product of (i) the Per ADS Merger Consideration and (ii) the number of Shares underlying such Company RSU.

(f) Any RCA issued by the Surviving Company in respect of any Unvested Company Option or Unvested Company RSU shall be subject to the same vesting conditions and schedules applicable to such Unvested Company Option or Unvested Company RSU, as applicable, without giving effect to the Transactions. On the date, and to the extent, that any Unvested Company Option or Unvested Company RSU would have become vested without giving effect to the Transactions, such corresponding portion of the RCA shall be delivered to the holder of such RCA, net of any applicable withholding Taxes, in US dollars by the Surviving Company.

(g) As of the Effective Date, all Company Share Awards shall automatically cease to exist, and each holder of a Company Share Award shall cease to have any rights with respect thereto, except the right to receive the cash payment or the RCA as provided in this Section 2.02.

5

(h) Any payment under this Section 2.02 shall be subject to all applicable Taxes and Tax withholding requirements. The Surviving Company shall pay through its payroll systems the amounts due pursuant to this Section 2.02.

Section 2.03 Dissenting Shares.

(a) Notwithstanding any provision of this Agreement to the contrary and to the extent available under the CICA, Shares that are issued and outstanding immediately prior to the Effective Date and that are held by shareholders who shall have validly exercised and perfected and not effectively withdrawn or lost their rights to dissent from the Merger in accordance with Section 238 of the CICA (collectively, the “Dissenting Shares”; holders of Dissenting Shares being referred to as “Dissenting Shareholders”) shall be cancelled and cease to exist at the Effective Date, and the Dissenting Shareholders shall not be entitled to receive the Per Share Merger Consideration, and shall instead be entitled to exercise the rights conferred by Section 238 of the CICA, except that all Shares held by Dissenting Shareholders who shall have failed to perfect or who effectively shall have withdrawn or lost their rights to dissent from the Merger under Section 238 of the CICA shall thereupon not be Dissenting Shares and shall be cancelled (and deemed to have been cancelled) and cease to exist as of the Effective Date in consideration for the right to receive the Per Share Merger Consideration, without any interest thereon, in accordance with Section 2.01(a) and shall be payable in the manner provided in Section 2.04.

(b) The Company shall give the Buyer Group (i) prompt notice of receipt of any written notices of objection, approval, of dissent and/or written demands or offers under Section 238 of the CICA received by the Company, attempted written withdrawals of such notices, demands or offers, and any other instruments served pursuant to applicable Law and received by the Company relating to its shareholders’ rights to dissent from the Merger and (ii) the opportunity to direct or approve all offers, negotiations and proceedings with respect to demands for appraisal under the CICA. The Company shall not, except with the prior written consent of the Buyer Group (such consent not be unreasonably withheld, conditioned or delayed), make any offers or payment with respect to any exercise by a shareholder of its rights to dissent from the Merger or any demands for appraisal or offer to settle or settle any such demands or approve any withdrawal of any such demands.

Section 2.04 Merger Consideration Payment Procedures.

(a) Paying Agent. Prior to the Effective Date, Parent shall appoint a bank or trust company selected by Parent and reasonably acceptable to the Company to act as paying agent (the “Paying Agent”) for purposes of paying (directly or through the Depositary) the holders of Shares and ADSs the payments required to be made pursuant to Sections 2.01(a), 2.01(b) and Section 2.03 (collectively, the “Merger Consideration”). At or prior to the Effective Date, Parent shall deposit, or cause to be deposited, with the Paying Agent, for the benefit of the holders of Shares and ADSs (other than the Continuing Shares and the Excluded Shares), cash in an amount sufficient to pay the Merger Consideration (such aggregate cash amount being hereinafter referred to as the “Exchange Fund”, and in case of payments under Section 2.03, an amount equal to the number of Dissenting Shares multiplied by the Per Share Merger Consideration). If for any reason following the Effective Date (including as a result of any Dissenting Shareholder effectively waiving, withdrawing or losing such Dissenting Shareholder’s rights to dissent to the

6

Merger) the cash in the Exchange Fund is insufficient to fully satisfy all of the payment obligations to be made in cash by the Paying Agent hereunder, Parent shall promptly deposit, or cause the Surviving Company to promptly deposit, cash in immediately available funds into the Exchange Fund in an amount that is equal to the deficiency in the amount of cash required to fully satisfy such cash payment obligations.

(b) Exchange Procedures. As promptly as practicable after the Effective Date (and in any event within three Business Days thereafter), the Surviving Company shall cause the Paying Agent to mail or otherwise disseminate to each person who was, immediately prior to the Effective Date, a registered holder of Shares entitled to receive the Per Share Merger Consideration pursuant to Section 2.01(a)): (i) a letter of transmittal (which shall be in customary form for a company incorporated in the Cayman Islands reasonably acceptable to Parent and the Company, and shall specify the manner in which the delivery of the aggregate Per Share Merger Consideration to registered holders of Shares (other than the Continuing Shares and Excluded Shares) shall be effected and contain such other provisions as the Buyer Group and the Company may mutually agree prior to the Effective Date) and (ii) instructions for use in effecting the surrender of any issued share certificates representing Shares (the “Share Certificates”) (or affidavits and indemnities of loss in lieu of the Share Certificates as provided in Section 2.04(c)) and/or such other documents as may be required in exchange for the Per Share Merger Consideration. Upon surrender of, if applicable, a Share Certificate (or affidavit and indemnity of loss in lieu of the Share Certificate as provided in Section 2.04(c)) and/or such other documents as may be required pursuant to such instructions to the Paying Agent in accordance with the terms of such letter of transmittal, duly executed in accordance with the instructions thereto, each registered holder of Shares represented by such Share Certificate (or affidavit and indemnity of loss in lieu of the Share Certificate as provided in Section 2.04(c)) and each registered holder of non-certificated Shares represented by book entry (the “Uncertificated Shares”), in each case, entitled to receive the Per Share Merger Consideration pursuant to Section 2.01(a) shall be entitled to receive in exchange therefor payment in the amount equal to (x) the number of Shares represented by such Share Certificate (or affidavit and indemnity of loss in lieu of the Share Certificate as provided in Section 2.04(c)) or the number of Uncertificated Shares, multiplied by (y) the Per Share Merger Consideration, and any Share Certificate so surrendered shall forthwith be marked as cancelled. Prior to the Effective Date, the Buyer Group and the Company shall establish procedures with the Paying Agent and the Depositary to ensure that (A) the Paying Agent will transmit to the Depositary as promptly as reasonably practicable following the Effective Date (but in any event not later than two Business Days thereafter) an amount in cash in immediately available funds equal to the product of (x) the number of Shares held by the Depositary immediately prior to the Effective Date (other than the Excluded Shares) and (y) the Per Share Merger Consideration, (B) the Depositary will distribute the Per ADS Merger Consideration to holders of ADSs pro rata to their holdings of ADSs (other than, if any, ADSs representing Excluded Shares) upon surrender by such holders of such ADSs, (C) until such distribution, the Depositary will invest the funds payable to holders of ADSs, as closely as possible, in the same manner as the Paying Agent invests the Exchange Fund pursuant to Section 2.04(e) (and earnings from investments shall be the sole and exclusive property of the Surviving Company), (D) holders of ADSs who are untraceable will be determined, and ADSs held by such holders will be treated, in the same manner as holders of Shares in Section 2.04(d) and (E) upon termination of the Deposit Agreement as contemplated in Section 2.06, the Depositary will deliver to the Paying Agent any portion of funds payable to holders of ADSs as a result of the Merger which remains undistributed to holders of ADSs as of

7

the date of such termination and the Paying Agent will thereafter pay amounts owed to holders of ADSs. Pursuant to the Deposit Agreement, the ADS holders will pay any applicable fees, charges and expenses of the Depositary and government charges (including any ADS cancellation or termination fee payable in accordance with the Deposit Agreement, but excluding withholding Taxes if any) due to or incurred by the Depositary in connection with the cancellation of the ADSs surrendered and 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 Shares or ADSs. In the event of a transfer of ownership of Shares prior to the Effective Date that is not registered in the register of members of the Company as of the Effective Date, the Per Share Merger Consideration in respect of such Shares will be paid to such transferee upon delivery of evidence to the reasonable satisfaction of the Surviving Company of such transferee’s entitlement to the relevant Share and to receive the Per Share Merger Consideration, to the exclusion of the applicable transferor and evidence that any applicable share transfer Taxes have been paid or are not applicable.

(c) Lost Certificates. If any Share Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Share Certificate to be lost, stolen or destroyed and, if required by the Surviving Company or the Paying Agent, the posting by such person of a bond, in such reasonable amount as the Surviving Company or the Paying Agent may direct, as indemnity against any claim that may be made against it with respect to such Share Certificate, the Paying Agent will pay in respect of the Shares represented by such lost, stolen or destroyed Share Certificate an amount equal to the Per Share Merger Consideration multiplied by the number of Shares represented by such Share Certificate to which the holder thereof is entitled pursuant to Section 2.01(a).

(d) Untraceable and Dissenting Shareholders. Remittances for the Per Share Merger Consideration or the Per ADS Merger Consideration, as the case may be, shall not be sent to holders of Shares or ADSs who are untraceable unless and until, except as provided below, they notify the Paying Agent or the Depositary, as applicable, of their current contact details. A holder of Shares or ADSs will be deemed to be untraceable if (i) such person has no registered address in the register of members (or branch register) maintained by the Company or the Depositary, as applicable, or (ii) on the last two consecutive occasions on which a dividend has been paid by the Company a check payable to such person either (x) has been sent to such person and has been returned undelivered or has not been cashed or (y) has not been sent to such person because on an earlier occasion a check for a dividend so payable has been returned undelivered, and in any such case no valid claim in respect thereof has been communicated in writing to the Company or the Depositary, as applicable, or (iii) notice of the Company Shareholders’ Meeting convened to vote on the Merger has been sent to such person and has been returned undelivered. Monies due to Dissenting Shareholders and shareholders of the Company who are untraceable shall be returned to the Surviving Company on demand for the benefit of Dissenting Shareholders and holders of Shares or ADSs who are untraceable. Dissenting Shareholders and holders of Shares or ADSs who are untraceable who subsequently wish to receive any monies otherwise payable in respect of the Merger within applicable time limits or limitation periods will be advised to contact the Surviving Company. Monies unclaimed after a period of seven years from the Closing Date shall be forfeited and shall revert to the Surviving Company.

(e) Investment of Exchange Fund. The Exchange Fund, pending its disbursement to the holders of Shares and ADSs, shall be invested by the Paying Agent as directed by Buyer Group or, after

8

the Effective Date, the Surviving Company in (i) short-term direct obligations of the United States of America, (ii) short-term obligations for which the full faith and credit of the United States of America is pledged to provide for the payment of principal and interest, (iii) short-term commercial paper rated the highest quality by either Moody’s Investors Service, Inc. or Standard and Poor’s Ratings Services or (iv) certificates of deposit, bank repurchase agreements or banker’s acceptances of commercial banks with capital exceeding $1 billion. Earnings from investments shall be the sole and exclusive property of the Surviving Company. To the extent that there are any losses with respect to any such investments, or the Exchange Fund diminishes for any reason below the level required for the Paying Agent to make prompt cash payment of Merger Consideration, the Buyer Group shall, or shall cause the Surviving Company to, promptly deposit cash into 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 of Merger Consideration. Except as contemplated by Section 2.04(b), this Section 2.04(e) and Section 2.04(f), the Exchange Fund shall not be used for any other purpose.

(f) Termination of Exchange Fund. Any portion of the Exchange Fund that remains undistributed to the holders of Shares or ADSs for six months after the Effective Date shall be delivered to the Surviving Company upon demand, and any holders of Shares and ADS who have not theretofore complied with this Article II shall thereafter look only to the Surviving Company for the cash to which they are entitled pursuant to Section 2.01(a) and 2.01(b). Any portion of the Exchange Fund remaining unclaimed by holders of Shares or ADSs as of a date which is immediately prior to such time as such amounts would otherwise escheat to or become property of any Governmental Authority shall, to the extent permitted by applicable law, become the property of the Surviving Company free and clear of any claims or interest of any person previously entitled thereto.

(g) No Liability. None of the Paying Agent, Parent, Merger Sub, the Surviving Company, the Depositary or any other person shall be liable to any former holder of Shares or ADSs for any such Shares or ADSs (or dividends or distributions with respect thereto), for cash delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.

(h) Withholding Rights. Each of Parent, Merger Sub, the Surviving Company, the Paying Agent and the Depositary (and any other person that has a payment obligation pursuant to this Agreement) shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement such amounts as it is required to deduct and withhold with respect to the making of such payment under any provision of applicable Law relating to Taxes. To the extent that amounts are so deducted or withheld by Parent, Merger Sub, the Surviving Company, the Paying Agent or the Depositary (or any other person that has a payment obligation pursuant to this Agreement), as the case may be, such deducted or withheld amounts shall be treated for all purposes of this Agreement as having been paid to the person in respect of which such deduction and withholding was made, and remitted to the applicable Governmental Authority.

Section 2.05 No Transfers.

From and after the Effective Date, (a) no transfers of Shares shall be effected in the register of members of the Company and (b) the holders of Shares (including Shares represented by ADSs) issued and outstanding immediately prior to the Effective Date (other than

9

Continuing Shares) shall cease to have any rights with respect to such Shares, except as otherwise provided in this Agreement or by Law.

Each Group Company is duly qualified or licensed to do business, and is in good standing (to the extent the relevant jurisdiction recognizes such concept of good standing), in each jurisdiction where the character of the properties and assets owned, leased, operated or used by it or the nature of its business makes such qualification or licensing necessary, except for any such failure to be so qualified or licensed or in good standing as would not have a Company Material Adverse Effect or would not be reasonably expected to, individually or in the aggregate, prevent, materially delay or materially impair the ability of the Company to consummate the Merger.

Concurrently with the preparation of the Proxy Statement, the Company, Parent and Merger Sub shall jointly prepare and cause to be filed with the SEC a Schedule 13E-3, and Parent and Merger Sub shall use their respective reasonable best efforts to cause all their respective Affiliates that are “engaged” in the Transactions (as determined in good faith by Parent and Merger Sub, as the case may be, based on applicable Law, including the SEC’s Compliance and Disclosure Interpretations, or as determined by the SEC) to join promptly the Company, Parent and Merger Sub to prepare and cause to be filed with the SEC a Schedule 13E-3 (with the Proxy Statement filed as an exhibit) in a timely manner. Each of the Company, Parent and Merger Sub shall use its reasonable best efforts so that the Schedule 13E-3 will comply as to form in all material respects with the requirements of the Exchange Act and the rules and regulations promulgated thereunder. Each of the Company, Parent and Merger Sub shall use its reasonable best efforts to respond promptly to any comments of the SEC with respect to the Proxy Statement and Schedule 13E-3. Each of the Company, Parent and Merger Sub shall furnish all information concerning such party to the others as may be reasonably requested in connection with the preparation, filing and distribution of the Proxy Statement and Schedule 13E-3 and the resolution of comments with respect thereto from the SEC. The Company shall promptly notify the Buyer Group upon the receipt of any written comments from the SEC or its staff or any request from the SEC or its staff for amendments or supplements to the Proxy Statement and Schedule 13E-3 and shall provide the Buyer Group with copies of all correspondence between it and its representatives, on the one hand, and the SEC and its staff, on the other hand. Prior to filing Schedule 13E-3 (or any amendment or supplement thereto) or mailing the Proxy Statement (or any amendment or supplement thereto) or responding to any comments of the SEC with respect thereto, the Company (i) shall provide the Buyer Group with a reasonable period of time to review and comment on such document or response and (ii) shall consider good faith comments reasonably proposed by the Buyer Group; provided, that each of Parent and Merger Sub shall, and shall use their respective reasonable best efforts to cause their respective Affiliates that are “engaged” in

21

the Transactions to, promptly furnish all information concerning such party to the others as may be reasonably requested and execute the Schedule 13E-3 (or any amendment or supplement thereto) for filing. If, at any time prior to the Company Shareholders’ Meeting, any information relating to the Company, Parent, Merger Sub or any of their respective Affiliates, officers or directors, is discovered by the Company, Parent or Merger Sub that should be set forth in an amendment or supplement to the Proxy Statement and Schedule 13E-3 so that the Proxy Statement and Schedule 13E-3 shall not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they are made, not misleading, the party that discovers such information shall promptly notify the other parties hereto and the Company shall file an appropriate amendment or supplement disclosing such information with the SEC and, to the extent required by applicable Law, disseminate such information to the shareholders of the Company.

(b) Each of the parties hereto represents and covenants to the other parties that the information supplied by it and its Affiliates (excluding, in the case of Parent, the Company and its Subsidiaries) and its and their Representatives for inclusion in the Proxy Statement and Schedule 13E-3 will not, at (i) the time the Proxy Statement and 13E-3 (or any amendment thereof or supplement thereto) are filed with the SEC, (ii) the time the Proxy Statement and Schedule 13E-3 (or any amendment thereof or supplement thereto) are first mailed to the shareholders of the Company and (iii) the time of the Company Shareholders’ Meeting, contain any untrue statement of a material fact or fail to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading.

(c) Each of the Company, Parent and Merger Sub shall ensure that all documents that it is responsible for filing with and/or furnishing to the SEC in connection with any of the Transactions will comply as to form and substance in all material respects with the applicable requirements of the Securities Act of 1933, as amended, the Exchange Act and the rules and regulations promulgated thereunder, other than with respect to any information supplied by the other parties.

Section 6.02 Shareholders’ Meetings.

(a) The Company shall, concurrently with or promptly after such time as the SEC confirms that it has no further comments on the Schedule 13E-3, (i) take all actions required under the CICA, the memorandum and articles of association of the Company and the applicable requirements of NASDAQ necessary to duly call, give notice of, convene and hold a shareholder meeting, (ii) with the assistance of Parent and Merger Sub, prepare and mail or cause to be mailed or otherwise disseminate the Proxy Statement to the holders of Shares (and concurrently furnish the Proxy Statement under Form 6-K to the SEC), including Shares represented by ADSs, as of the record date established for the shareholders’ meeting (the “Company Shareholders’ Meeting”), for the purpose of voting upon the authorization of the Plan of Merger, and (iii) instruct or otherwise cause the Depositary to (A) fix the record date established by the Company for the Company Shareholders’ Meeting as the record date for determining the holders of ADSs who shall be entitled to give instructions for the exercise of the voting rights pertaining to the Shares represented by ADSs (the “Record ADS Holders”), (B) provide all proxy solicitation materials to

22

all Record ADS Holders and (C) vote all Shares represented by ADSs in accordance with the instructions of such corresponding Record ADS Holders. Without the consent of Parent and Merger Sub, authorization and approval of this Agreement, the Plan of Merger and the Transactions, including the Merger, shall be the only matter (other than procedural matters) to be proposed to be voted upon by the shareholders of the Company at the Company Shareholders’ Meeting.

(b) Subject to this Section 6.02, the Company Board shall recommend to holders of the Shares that they authorize and approve this Agreement, the Plan of Merger and the Transactions, including the Merger, and shall include such recommendation in the Proxy Statement. Without limiting the generality of the foregoing sentence, the Company agrees that, unless this Agreement is validly terminated in accordance with Article VIII, its obligations pursuant to this Section 6.02 (including its obligations to call, give notice of, convene and hold the Company Shareholders’ Meeting and to solicit from its shareholders proxies, in each case, in accordance with this Section 6.02) shall not be affected by the commencement, public proposal, public disclosure, announcement, communication or submission to the Company or any other person of any Competing Transaction, or by any Change in the Company Recommendation. The Company shall use its reasonable best efforts to solicit from its shareholders proxies in relation to the Company Shareholders’ Meeting.

(c) The Company shall duly convene and hold the Company Shareholders’ Meeting as soon as reasonably practicable following the mailing of the Proxy Statement, unless this Agreement is validly terminated in accordance with Article VIII. Notwithstanding anything to the contrary contained in Section 6.02(b), after consultation in good faith with the Buyer Group, the Company may recommend the adjournment of the Company Shareholders’ Meeting to its shareholders (i) to the extent necessary to ensure that any required supplement or amendment to the Proxy Statement is provided to the holders of Shares within a reasonable amount of time in advance of the Company Shareholders’ Meeting, (ii) as otherwise required by applicable Law, or (iii) if as of the time for which the Company Shareholders’ Meeting is scheduled as set forth in the Proxy Statement, there are insufficient Shares represented (in person or by proxy) to constitute a quorum necessary to conduct the business of the Company Shareholders’ Meeting. If the Company Shareholders’ Meeting is adjourned, unless this Agreement is validly terminated in accordance with Article VIII, the Company shall convene and hold the Company Shareholders’ Meeting as soon as reasonably practicable thereafter.

Section 6.03 Access to Information.

From the date hereof until the Effective Date and subject to applicable Law, upon reasonable advance notice from Parent or Merger Sub, the Company shall (i) provide to Parent and Merger Sub (and Parent’s or Merger Sub’s respective officers, directors, employees, accountants, consultants, financial and legal advisors, agents, financing sources and other representatives, collectively, “Representatives”) reasonable access during normal business hours to the offices, properties, books and records of any Group Company, (ii) furnish to Parent, Merger Sub and their respective Representatives such existing financial and operating data and other existing information as such persons may reasonably request and (iii) instruct its and its Subsidiaries’ Representatives to reasonably cooperate with Parent, Merger Sub and their respective Representatives in their investigation; provided, that any such investigation shall be

23

conducted in such a manner as not to interfere unreasonably with the business or operations of the Company or its Subsidiaries or otherwise result in any significant interference with the timely discharge by the employees of the Company or its Subsidiaries of their duties and to the extent reasonably practicable with the resources readily available to the Company and not burdensome or disruptive to the Company’s business; provided, further, that the Company shall not be required to provide Parent, Merger Sub or any of their respective Representatives with access to any books, records, documents or other information to the extent that (x) such books, records, documents or other information are subject to any confidentiality agreement with a Third Party (provided, that at the request of Parent or Merger Sub, the Company shall use its commercially reasonable efforts to obtain a waiver from such Third Party), (y) the disclosure of such books, records, documents or other information would result in the loss of attorney-client or other legal privilege and joint defense or similar doctrines or workarounds would not be available or effective to preserve privilege, or (z) the disclosure of such books, records, documents or other information is prohibited by applicable Law. Nothing in this Agreement shall require any of the Company and its Subsidiaries to disclose any information to Parent or Merger Sub to the extent such disclosure would, in the Company’s reasonable discretion, (i) jeopardize any attorney-client or other legal privilege or (ii) contravene any applicable Law or binding confidentiality obligation of the Company or any of its Subsidiary or Affiliate, provided that the Company has used reasonable best efforts to make appropriate substitute arrangements to permit reasonable disclosure not in violation of such applicable Law or obligation.

Section 6.04 No Solicitation of Transactions.

(a) The Company agrees that neither it nor any of its Subsidiaries will, and that it will direct its and its Subsidiaries’ Representatives (including any investment banker, attorney or accountant retained by any Group Company), not to, in each case, directly or indirectly, (i) solicit, initiate or knowingly encourage (including by way of furnishing nonpublic information in a manner designed to knowingly encourage), or take any other action to knowingly facilitate, any inquiries or the making of any proposal or offer (including any proposal or offer to its shareholders) with respect to any Competing Transaction, (ii) enter into, maintain or continue discussions or negotiations with, or provide any nonpublic information relating to the Company or the Transactions to, any person or entity in furtherance of such inquiries or to obtain a proposal or offer for a Competing Transaction, (iii) agree to, approve, endorse or recommend any Competing Transaction or enter into any letter of intent or Contract or commitment contemplating or otherwise relating to any Competing Transaction (in each case, other than as permitted pursuant to Section 6.04(b)) or (iv) authorize or permit any of the officers, directors or Representatives of the Company or any of its Subsidiaries acting directly or indirectly under the direction of the Company or any of its Subsidiaries, to take any action set forth in clauses (a)(i) - (a)(iii) of this Section 6.04. The Company shall not, and shall cause its Subsidiaries not to, enter into any confidentiality agreement with any Third Party subsequent to the date hereof which prohibits the Company from providing non-public information concerning the Company or any of its Subsidiaries to Buyer Group or release any Third Party from, or waive any provision of, any confidentiality or standstill agreement to which it is a party in respect of any Competing Transaction. The Company shall notify the Buyer Group as promptly as reasonably practicable (and in any event within 48 hours after the Company and/or the Special Committee attains knowledge thereof), orally and in writing, of any proposal or offer with respect to, or any request for non-public information concerning the Company or any of its Subsidiaries in connection with

24

a Competing Transaction, specifying (x) the material terms and conditions thereof (including, if applicable, material amendments or proposed material amendments) and providing, if applicable, copies of any written requests, proposals or offers, including proposed agreements, and (y) the identity of the party making such proposal, offer or request, unless the disclosure of such identity would be prohibited by a confidentiality agreement in effect on the date hereof. The Company shall keep Buyer Group informed, on a reasonably current basis (and in any event within 48 hours of the occurrence of any material change, development, discussion or negotiation) of the status and terms of any such proposal, offer or request and of any material changes in the status and terms of any such proposal, offer or request (including the material terms and conditions thereof). Without limiting the foregoing, the Company shall provide the Buyer Group with 48 hours’ prior notice (or such lesser prior notice as is provided to members of the Company Board or members of the Special Committee) of any meeting of the Company Board or Special Committee at which the Company Board or Special Committee, as applicable, will be requested to consider any Competing Transaction. Immediately upon the execution and delivery of this Agreement, the Company shall cease and cause to be terminated all existing discussions or negotiations with any parties conducted heretofore with respect to any possible Competing Transaction.

(b) Except as set forth in this Section 6.04, neither the Company Board nor any committee thereof shall (i) change, withhold, withdraw, qualify or modify, or publicly propose to change, withhold, withdraw, qualify or modify, in each case, in a manner adverse to Parent or Merger Sub, the Company Recommendation, or fail to include the Company Recommendation in the Proxy Statement (each, a “Change in the Company Recommendation”), (ii) authorize, approve or recommend, or publicly propose to authorize, approve or recommend to the shareholders of the Company, an offer or proposal with respect to a Competing Transaction, (iii) if a tender offer or exchange offer for 20% or more of the outstanding share capital of the Company that constitutes a Competing Transaction is commenced, fail to recommend against acceptance of such tender offer or exchange offer by its shareholders within 10 Business Days after commencement, which shall constitute a failure to recommend against acceptance of such tender offer or exchange offer; provided, that a customary “stop, look and listen” communication by the Company Board or the Special Committee to shareholders of the Company pursuant to Rule 14d-9(f) of the Exchange Act shall not be deemed to be a Change in the Company Recommendation or violate this Section 6.04, or (iv) approve or recommend, cause or permit the Company to enter into, or submit to a vote by its shareholders, any letter of intent, memorandum of understanding, agreement in principle, merger agreement, acquisition agreement or other similar document or Contract with respect to any Competing Transaction (any of the foregoing in this clause (iv), an “Alternative Acquisition Agreement”).

(c) Notwithstanding the foregoing, if the Company Board determines, in its good faith judgment upon the recommendation of the Special Committee, in its good faith judgment, prior to the time of the Company Shareholders’ Meeting and upon advice by its independent legal counsel, that failure to make a Change in the Company Recommendation would be inconsistent with its fiduciary obligations to the Company and its shareholders under applicable Law, the Company Board may, upon the recommendation of the Special Committee, effect a Change in the Company Recommendation, provided, that the Company Board shall (i) provide five Business Days’ prior written notice to Parent and Merger Sub advising Parent and Merger Sub that the Company Board intends to effect a Change of Recommendation and specifying in reasonable detail the facts

25

underlying and the reasons for the decision by the Company Board (acting upon the recommendation of the Special Committee) to take such action and (ii) during such five Business Day period, if requested by Parent and Merger Sub, engage in good faith negotiations with Parent and Merger Company to amend this Agreement in such a manner that obviates the need for such Change in the Company Recommendation.

(d) A “Competing Transaction” means any of the following (other than the Transactions): (i) any merger, consolidation, share exchange, business combination, scheme of arrangement, amalgamation, recapitalization, liquidation, dissolution or other similar transaction involving the Company or any of its Subsidiaries whose assets, individually or in the aggregate, constitute 20% or more of the consolidated assets of the Company or to which 20% or more of the net revenue or net income of the Company are attributable, (ii) any sale, lease, exchange, transfer or other disposition of assets or businesses that constitute or represent 20% or more of the net revenue or net income or assets of the Company and its Subsidiaries, taken as a whole, (iii) any sale, exchange, transfer or other disposition of 20% or more of any class of equity securities of the Company, (iv) the acquisition (whether by merger, consolidation, equity investment, share exchange, joint venture or otherwise) by any Third Party, directly or indirectly, of any equity interest in any entity that holds assets representing, directly or indirectly, 20% or more of the net revenue, net income or assets of the Company and its Subsidiaries, taken as a whole, or (v) any tender offer or exchange offer that, if consummated, would result in any person beneficially owning 20% or more of any class of equity securities of the Company, or (vi) any combination of the foregoing.

(e) Nothing contained in this Section 6.04 and Section 6.02 shall be deemed to prohibit the Company, the Company Board or the Special Committee from (i) complying with its disclosure obligations under U.S. federal or state or non-U.S. Law, including (A) disclosure of factual information regarding the business, financial condition or results of operations of the Company or (B) taking and disclosing to its shareholders a position contemplated by Rule 14e-2(a), Rule 14d-9 or Item 1012(a) of Regulation M-A promulgated under the Exchange Act (or any similar communication to shareholders in connection with the making or amendment of a tender offer or exchange offer); provided, that any such disclosure pursuant to this clause (B) with respect to a Competing Transaction (other than a “stop, look and listen” communication of the type contemplated by Rule 14d-9(f) under the Exchange Act or a statement that the Company Board or the Special Committee has received and is currently evaluating such Competing Transaction) that does not include an express rejection of any applicable Competing Transaction or an express reaffirmation of its recommendation in favor of the Transactions shall be deemed to be a Change in the Company Recommendation or (ii) making any “stop-look-and-listen” communication of the type contemplated by Rule 14d-9(f) under the Exchange Act.

Section 6.05 Directors’ and Officers’ Indemnification and Insurance.

(a) The memorandum and articles of association of the Surviving Company shall contain provisions no less favorable with respect to exculpation and indemnification than are set forth in the memorandum and articles of association of the Company as in effect on the date hereof, which provisions shall not be amended, repealed or otherwise modified for a period of six years from the Effective Date in any manner that would affect adversely the rights thereunder of

26

individuals who, at or prior to the Effective Date, were directors, officers, employees, fiduciaries or agents of the Company, unless such modification shall be required by Law.

(b) The Surviving Company shall maintain in effect for six years from the Effective Date, the current directors’ and officers’ liability insurance policies maintained by the Company with respect to matters occurring prior to the Effective Date, including acts or omissions occurring in connection with this Agreement and the consummation of the Transactions (the parties covered thereby, the “Indemnified Parties”); provided, that the Surviving Company may substitute therefor policies of at least the same coverage containing terms and conditions that are no less favorable than those provided under the Company’s current policies; provided, further, that in no event shall the Surviving Company be required to expend pursuant to this Section 6.05(b) more than an amount per year equal to 300% of the aggregate annual premium most recently paid by the Company for the directors’ and officers’ liability insurance policies prior to the date hereof (the “Maximum Amount”). If the Company or Surviving Company is unable to obtain the directors’ and officers’ liability insurance required by this Section 6.05(b), Parent shall cause the Surviving Company to obtain as much comparable insurance as possible during such six year period for a premium which shall not exceed the Maximum Amount. Alternatively, the Company may and, at the joint request of Parent and Merger Sub, the Company shall, purchase a six-year “tail” prepaid policy prior to the Effective Date on terms and conditions no less advantageous to the Indemnified Parties than the existing directors’ and officers’ liability insurance maintained by the Company. Notwithstanding anything to the contrary set forth in this Agreement, if such “tail” prepaid policies have been obtained by the Company prior to the Effective Date, the Surviving Company shall maintain such policies in full force and effect, and continue to honor the respective obligations thereunder, and all other obligations of the Surviving Company under this Section 6.05(b) shall terminate.

(c) Subject to the terms and conditions of this Section 6.05, from and after the Effective Date, the Surviving Company shall comply with all of the Company’s obligations, and shall cause its Subsidiaries to comply with their respective obligations to indemnify and hold harmless (including any obligations to advance funds for expenses) the present and former officers and directors thereof against any and all costs or expenses (including reasonable attorneys’ fees and expenses), judgments, fines, losses, claims, damages, liabilities and amounts paid in settlement in connection with any actual or threatened claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative (“Damages”), arising out of, relating to or in connection with (i) the fact that such person is or was a director or officer of the Company or such Subsidiary or (ii) any acts or omissions by such person in such capacity prior to or at the Effective Date (including acts or omissions with respect to the approval of this Agreement or the Transactions or arising out of or pertaining to the Transactions and actions to enforce this provision or any other indemnification or advancement right of any Indemnified Party), to the extent provided under the Company’s or such Subsidiaries’ respective organizational and governing documents or agreements in effect on the date hereof and to the fullest extent permitted by the CICA or any other applicable Law on the date hereof, including the approval of this Agreement, the Transactions or arising out of or pertaining to the Transactions and actions to enforce this provision or any other indemnification or advancement right or any such person; provided, that such indemnification shall be subject to any limitation imposed from time to time under applicable Law.

27

(d) In the event the Surviving Company or any of its successors or assigns (i) consolidates with or merges into any other person and shall not be the continuing or surviving company or entity of such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any person, then, and in each such case, proper provision shall be made so that the successors and assigns of the Surviving Company shall assume the obligations set forth in this Section 6.05.

(e) The provisions of this Section 6.05 shall survive the consummation of the Merger and are intended to be for the benefit of, and shall be enforceable by, each of the Indemnified Parties and their heirs and legal representatives, each of which shall be a third- party beneficiary of the provisions of this Section 6.05.

(f) Nothing in this Agreement is intended to, shall be construed to or shall release, waive or impair any rights to directors’ and officers’ insurance claims under any policy that is or has been in existence with respect to the Company or any of its Subsidiaries or their respective officers, directors and employees, it being understood and agreed that the indemnification provided for in this Section 6.05 is not prior to or in substitution for any such claims under any such policies.

Section 6.06 Notification of Certain Matters.

Each of the Company, Parent and Merger Sub shall promptly notify the other in writing of:

(a) any notice or other communication received by such party from any person alleging that the consent of such person is or may be required in connection with the Transactions;

(b) any notice or other communication received by such party from any Governmental Authority in connection with the Transactions;

(c) any Actions commenced or, to the knowledge of the Company or the knowledge of Parent or the knowledge of Merger Sub, threatened against the Company or any of its Subsidiaries or Parent and any of its Affiliates (excluding the Company and its Subsidiaries) or Merger Sub and any of its Affiliates, as the case may be, that, if pending on the date of this Agreement, would have been required to have been disclosed by such party pursuant to any party’s representations and warranties contained herein, or that relate to such party’s ability to consummate the Transactions; and

(d) if a breach of any representation or warranty or failure to perform any covenant or agreement on the part of such person set forth in this Agreement shall have occurred that would cause the conditions set forth in Section 7.01, Section 7.02 and Section 7.03 not to be satisfied together, in each case, with a copy of any such notice, communication or Action; provided, that the delivery of any notice pursuant to this Section 6.06 shall not limit or otherwise affect the remedies available hereunder to the party receiving such notice; provided, further, that failure to give notice pursuant to this Section 6.06 shall not constitute a failure of a condition to the Merger set forth in Article VII except to the extent that the underlying breach of a representation or warranty or failure to perform any covenant or agreement not so notified would, standing alone, constitute such a failure.

28

Section 6.07 Equity Financing.

(a) Parent shall use its reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable to arrange, obtain and consummate the Equity Financing on the terms and conditions set forth in the Equity Commitment Letters no later than the Closing Date, and shall not permit any amendment, supplement or modification to be made to, or any waiver of any provision under, or any replacement of, any Equity Commitment Letter if such amendment, modification, supplement, waiver or replacement would (A) reduce (or could have the effect of reducing) the aggregate amount of the Equity Financing; (B) impose new or additional conditions or contingencies or otherwise expand, amend or modify any of the conditions to the Equity Financing; or (C) otherwise expand, amend or modify any other provision of such Equity Commitment Letter in a manner that would reasonably be expected to (1) delay or prevent or make less likely the funding of the Equity Financing on the Closing Date or otherwise prevent, delay or impair consummation of the Transactions or (2) adversely impact the ability of Parent, Merger Sub or the Company to timely consummate the Transactions or the timing of Closing, including by making funding the Equity Financing less likely to occur, or enforce its rights against the counterparties to the applicable Equity Commitment Letter or any definitive agreements with respect thereto or to consummate the Transactions. Parent shall promptly deliver to the Company copies of any amendment, supplement, modification, waiver or replacement of any Equity Commitment Letter.

(b) Parent shall use its reasonable best efforts (A) to maintain in full force and effect the Equity Commitment Letters until consummation of the Transactions; (B) to satisfy on a timely basis (or obtain the waiver of) all of the conditions and covenants applicable to Parent in the Equity Commitment Letters and any such definitive agreements with respect thereto; (C) if all of the conditions set forth in Section 7.01 and Section 7.02 and the Equity Commitment Letters have been or as of the Closing will be satisfied or waived, to consummate the Equity Financing at or prior to the Closing in accordance with the terms of the Equity Commitment Letters; (D) to enforce its rights (including through litigation) under each Equity Commitment Letter, subject to the terms thereof, to cause the applicable counterparty to comply with its obligations under such Equity Commitment Letter and any related definitive agreements; and (E) to comply with its obligations under each Equity Commitment Letter and any related definitive agreements.

(c) Without limiting the generality of the foregoing, Parent shall give the Company prompt written notice (and, in any event, within one (1) Business Day) of (A) the termination or expiration of any Equity Commitment Letter or any related definitive agreements, (B) any breach or default (or any event or circumstance that, with or without notice, lapse of time or both, could reasonably be expected to give rise to any such breach or default) by Parent, or, to the knowledge of Parent, any other party to such Equity Commitment Letter or any related definitive agreements, (C) the receipt of (1) any notice or (2) other communication, in each case, from Morningside or JWCA with respect to any (x) actual, threatened or alleged breach, default, termination or repudiation by any party to the applicable Equity Commitment Letter or any related definitive agreements or of any provisions of such Equity Commitment Letter or any related definitive agreements (including any proposal by Morningside or JWCA, as applicable, to withdraw, terminate or make any material change in the terms of (including the amount of the Equity Financing contemplated by) such Equity Commitment Letter or (y) material dispute or disagreement between or among any parties to such Equity Commitment Letter or any related

29

definitive agreements with respect to the obligation to fund the Equity Financing or the amount of the Equity Financing to be funded at Closing, and (D) if at any time for any reason Parent believes in good faith that there is a possibility that it will not be able to obtain all or any portion of the Equity Financing on the terms and conditions, in the manner or from the sources contemplated by the applicable Equity Commitment Letter or any related definitive agreements. Without limiting the foregoing, as soon as reasonably practicable, but in any event within two (2) Business Days of the date the Company delivers to Parent a written request therefor, Parent shall provide to the Company and its Representatives any and all information reasonably requested by the Company relating to any circumstances referred to in clause (A), (B), (C) or (D) of the immediately preceding sentence.

(d) If any portion of the Equity Financing becomes unavailable on the terms and conditions contemplated in the Equity Commitment Letters, Parent shall use its reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable to arrange to obtain alternative financing from alternative sources in an amount sufficient, when added to the portion of the Equity Financing that is available, to consummate the Transactions and to pay all related expenses (“Alternative Financing”) as promptly as practicable following the occurrence of such event and to obtain and provide the Company with a copy of, the new financing commitment that provides for such Alternative Financing and all contracts, engagement letters and other arrangements associated therewith; provided, further, that Parent shall advise the Company in writing of the maximum amount of expenses payable by the Parent or its Affiliates under such commitment letter(s) and engagement letter(s)) (such commitment Letter(s) and related term sheets, including all exhibits, schedules and annexes, and each such engagement letter, as such documents may be amended, supplemented, modified, waived or replaced, collectively, the “Alternative Financing Commitment Letter”)). As applicable, references in this Agreement (A) to “Equity Financing” shall include Alternative Financing and (B) to any “Equity Commitment Letter” shall include the Alternative Financing Commitment Letter.

(e) Notwithstanding anything herein to the contrary, Parent and Merger Sub acknowledge and agree that the obtaining of the Equity Financing is not a condition to Closing, and reaffirms its obligation to consummate the Transactions irrespective and independent of the availability of the Equity Financing, subject to the applicable conditions set forth in Section 7.01 and Section 7.02.

Section 6.08 [Reserved]

Section 9.08 Specific Performance.

(a) Subject to Section 9.08(b), the parties hereto agree that irreparable damage would occur in the event that any provision of this Agreement were not performed in accordance with the terms hereof by the applicable party or parties, and that money damages or other legal remedies would not be an adequate remedy therefor. Accordingly, the parties hereto acknowledge and hereby agree that in the event of any breach by the Company, on the one hand, or Parent and Merger Sub, on the other hand, of any of their respective covenants or obligations set forth in this Agreement, the Company, on the one hand, or Parent and Merger Sub, on the other hand, shall, subject to Section 8.06, be entitled to specific performance of the terms hereof (including the other parties’ obligation to consummate the Transactions, subject in each case to the terms and conditions of this Agreement), including an injunction or injunctions to prevent breaches of this Agreement, in addition to any other remedy at law or equity.

(b) Notwithstanding anything to the contrary set forth in this Agreement, it is explicitly agreed that the Company shall be entitled seek to specific performance or injunctive relief with respect to Parent’s obligation to cause the Equity Financing to be funded and Parent’s and Merger Sub’s obligations to consummate the Transactions if (i) the conditions precedent to Parent’s and Merger Sub’s obligations in Section 7.01 and Section 7.02 have been satisfied (other than those conditions that, by their nature, are to be, and will be, satisfied by actions taken at the Closing or will be waived by Parent and Merger Sub); and (ii) the Company has irrevocably confirmed to Parent and Merger Sub in writing that (A) all of the conditions set forth in Section 7.01 and Section 7.03 have been satisfied (other than those conditions that, by their terms, are to be, and will be, satisfied by actions taken at the Closing or will be waived by the Company) and (B) the Company is prepared to consummate the Closing and, if specific performance is granted and the Equity Financing is funded, then the Closing will occur; provided, that notwithstanding the foregoing, the Company shall not be entitled to seek enforcement of the Equity Financing pursuant to terms of any Equity Commitment Letter unless and until (i) the Company also seeks enforcement of the Equity Financing in the same manner pursuant to the other Equity Commitment Letter or (ii) the Commitment (as defined in the other Equity Commitment Letter) has been funded in full.

(c) Each party waives (i) any defenses in any action for an injunction or other appropriate form of specific performance or equitable relief, including the defense that a remedy at law would be adequate, and (ii) any requirement under any Law to post a bond or other security as a prerequisite to obtaining an injunction or other appropriate form of specific performance or equitable relief. Notwithstanding anything herein to the contrary, (x) while the parties hereto may pursue both a grant of specific performance or equitable relief and the payment of the amounts set forth in Section 8.06, neither Parent and Merger Sub, on the one hand, nor the Company, on the other hand, shall be permitted or entitled to receive both a grant of specific performance or equitable relief and payment of such amounts, and (y) upon the payment of such amounts, the remedy of specific performance or equitable relief shall not be available against the

46

party making such payment and, if such party is Parent or Merger Sub, any other member of the Investors Group or, if such party is the Company, any other member of the Company Group, and each party agrees to cause any Action (whether such Action is being prosecuted by the Company or any other member of the Company Group) pending against any member in the Investors Group or Company Group (as the case may be) to be dismissed with prejudice at such time as, in connection with this Agreement or any of the Transactions (including the Equity Financing), any such amounts are paid by the applicable party.

(d) If any party brings any Action to enforce specifically the performance of the terms and provisions hereof, the Termination Date shall automatically be extended by (i) the amount of time during which such Action is pending, plus 20 Business Days or (ii) such other time period established by the court presiding over such Action.

(e) This Section 9.08 shall not be deemed to alter, amend, supplement or otherwise modify the terms of the Equity Commitment Letters (including the expiration or termination provisions thereof).

Each of the parties hereto agrees that mailing of process or other papers in connection with any such Action in the manner provided in Section 9.02 or in such other manner as may be permitted by applicable Laws, will be valid and sufficient service thereof. Each of the parties hereto hereby (a) submit to the exclusive jurisdiction of any federal or state court sitting in the Borough of Manhattan of The City of New York for the purpose of any Action arising under the Laws of the State of New York out of or relating to this Agreement brought by any party hereto and (b) irrevocably waives, and agrees not to assert, by way of motion, as a defense, counterclaim or otherwise, in any Action with respect to this Agreement and the rights and obligations arising hereunder, or for recognition and enforcement of any judgment in respect of this Agreement and the rights and obligations arising hereunder (i) any claim that it is not

47

personally subject to the jurisdiction of the aforesaid courts for any reason other than the failure to serve process in accordance with this Section 9.09, (ii) any claim that it or its property is exempt or immune from the jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise) and (iii) to the fullest extent permitted by applicable Law, any claim that (A) the Action in such court is brought in an inconvenient forum, (B) the venue of such Action is improper or (C) this Agreement, or the subject matter hereof, may not be enforced in or by such courts.

EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY WITH RESPECT TO ANY ACTION OR LIABILITY DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT, THE EQUITY COMMITMENT LETTERS, THE LIMITED GUARANTEES, THE EQUITY FINANCING OR THE TRANSACTIONS.

48

Any such extension or waiver shall be valid if set forth in an instrument in writing signed by the party or parties to be bound thereby. No failure or delay by any party in exercising any right, power or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege.

Any determination hereunder as to whether any action, document or matter is acceptable to the Company, or reasonably acceptable to the Company, or similar determinations, shall be made by the Company Board acting upon the recommendation of the Special Committee. Whenever in this Agreement a determination, decision or approval by the Company is called for, or any action or remedy is provided for the benefit of the Company, including (a) any consent, determination or action by the Company hereunder, including any amendment to or waiver of any provision of this Agreement, any extension of the time for performance of any obligation or action hereunder by the Company and termination of this Agreement by the Company, or (b) any exercise of the Company’s rights or remedies under this Agreement or any action on behalf of the Company to enforce such rights and remedies or any obligation of the Buyer Group, Parent or Merger Sub under this Agreement, then such determination, decision, approval, action or exercise of such right or remedy must be first considered by the Special Committee and may only be taken by the Company following the Company’s Board’s consideration of the Special Committee’s recommendation in respect of such determination, decision, approval, action or exercise of such right or remedy.
