ARTICLE II

CONVERSION AND CANCELLATION OF SECURITIES

Section 2.1 Conversion and Cancellation of Securities. At the Effective Time, by virtue of the Merger and without any action on the part of any of the Parties or any other shareholders of VanceInfo:

(a) Securities of Merger Sub. The ordinary share, par value US$1.00 per share, of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into a fully paid and nonassessable ordinary share, par value US$0.001 per share, of the Surviving Corporation. Such ordinary share shall be the only issued and outstanding share capital of the Surviving Corporation.

(b) Merger Consideration.

(i) Other than as provided in Section 2.1(b)(ii), subject to the consummation of the Share Consolidation, each ordinary share, par value US$0.001 per share, of VanceInfo issued and outstanding immediately prior to the Effective Time (individually, a “VanceInfo Share” and collectively, the “VanceInfo Shares”) (other than the Excluded Shares), shall be cancelled in exchange for the right to receive one (the “Share Exchange Ratio”) validly issued, fully paid, non-assessable common share of HiSoft (“HiSoft Share”) which as of the date of this Agreement, has a, par value of US$0.0001 per share and, immediately prior to the Effective Time will have a par value of US$0.00139482 per share (the “Per Share Merger Consideration”).

(ii) Subject to the consummation of the Share Consolidation and the ADS Adjustment, each American depositary share of VanceInfo, each of which represents one VanceInfo Share (the “VanceInfo ADSs”), shall be cancelled in exchange for the right of the holder of the relevant VanceInfo ADS at the direction of the VanceInfo Depositary to receive one (the “ADS Exchange Ratio”) American depositary share of HiSoft (the “HiSoft ADS”) which, as of the date of this Agreement represents 19 HiSoft Shares and immediately prior to the Effective Time, will represent one HiSoft Share (the “Per ADS Merger Consideration” and together with the Per Share Merger Consideration, the “Merger Consideration”).

As of the Effective Time, all VanceInfo Shares, including VanceInfo Shares represented by VanceInfo ADSs, shall, by virtue of the Merger and without any action on the part of its holder, automatically be cancelled, shall no longer be issued or outstanding and shall cease to exist and the register of members of

VanceInfo will be amended accordingly. Each VanceInfo Share (other than the Excluded Shares) shall thereafter represent only the right to receive the Per Share Merger Consideration and each VanceInfo Share represented by a VanceInfo ADS, together with such VanceInfo ADS, shall thereafter represent only the right to receive the Per ADS Merger Consideration, as the case may be, in each case without interest.

(c) Cancellation of VanceInfo Shares. Notwithstanding Section 2.1(b), each VanceInfo Share and each VanceInfo ADS issued and outstanding immediately prior to the Effective Time that is (i) issued to the VanceInfo Depositary and reserved for future grants under the VanceInfo Share Incentive Plans, (ii) repurchased and held by VanceInfo in treasury or by the VanceInfo Depositary either in the form of VanceInfo Shares or VanceInfo ADSs, or (iii) owned by HiSoft Merger Sub or any direct or indirect subsidiary of HiSoft Merger Sub or VanceInfo (collectively, the “Excluded Shares”) shall, by virtue of the Merger and without any action on the part of its holder, automatically be cancelled, shall no longer be issued or outstanding and shall cease to exist, and the register of members of VanceInfo will be amended accordingly, and no consideration shall be delivered or deliverable in exchange therefor.

(d) Untraceable Shareholders. The Per Share Merger Consideration shall not be issued or delivered to VanceInfo shareholders who are untraceable unless, except as provided below, such VanceInfo shareholders provide written notice of their current contact details to the Exchange Agent prior to the Effective Time. A VanceInfo shareholder will be deemed to be untraceable if (i) such shareholder has no registered address in the register of members maintained by VanceInfo, (ii) on the last two consecutive occasions on which a dividend has been paid by VanceInfo, a check payable to such shareholder either (A) has been sent to such shareholder and has been returned undelivered or has not been cashed or (B) has not been sent to such shareholder 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 VanceInfo or (iii) notice of the VanceInfo Shareholders Meeting has been sent to such shareholder and has been returned undelivered.

(e) Certain Adjustments. Notwithstanding any provision of this Article II to the contrary, if between the date of this Agreement and the Effective Time the outstanding VanceInfo Shares or HiSoft Shares, as applicable, or securities convertible into or exchangeable or exercisable for VanceInfo Shares or HiSoft Shares, as applicable, shall have been changed into a different number of shares or a different class by reason of the occurrence or record date of any share dividend, subdivision, reclassification, recapitalization, split, reverse split, combination, consolidation, readjustment, exchange of shares or similar transaction, the Per Share Merger Consideration and Per ADS Merger Consideration, respectively, shall be appropriately adjusted to reflect such share dividend, subdivision, reclassification, recapitalization, split, reverse split, combination, consolidation, readjustment, exchange of shares or similar transaction; provided that no such adjustment shall be made in connection with the Share Consolidation.

Section 2.2 Treatment of VanceInfo Equity Awards.

(a) Each VanceInfo Option that is outstanding immediately prior to the Effective Time, whether or not exercisable or vested, shall, at the Effective Time, be assumed by HiSoft and be replaced by HiSoft with a HiSoft Option. Each such HiSoft Option shall be exercisable for that number of whole HiSoft Shares (rounded down to the nearest whole share) equal to the product of (i) the total number of VanceInfo Shares subject to such VanceInfo Option multiplied by (ii) the Share Exchange Ratio, at an exercise price per HiSoft Share (rounded up to the nearest whole cent) equal to the quotient obtained by dividing (x) the exercise price per share of such VanceInfo Option by (y) the Share Exchange Ratio. Each

such HiSoft Option shall otherwise continue to have, and shall be subject to, the same terms and conditions as applied to such VanceInfo Option immediately prior to the Effective Time.

(b) Each VanceInfo RSU that is outstanding immediately prior to the Effective Time, whether vested or unvested, shall, at the Effective Time, be assumed by HiSoft and be replaced by HiSoft with a number of HiSoft restricted share units (“HiSoft RSUs”) equal to the product of (i) the total number of VanceInfo Shares subject to such VanceInfo RSU multiplied by (ii) the Share Exchange Ratio, rounded down to the nearest whole HiSoft Shares. Each such HiSoft RSU shall otherwise continue to have, and shall be subject to, the same terms and conditions as applied to such VanceInfo RSU immediately prior to the Effective Time.

(c) The VanceInfo Share Incentive Plans and all obligations thereunder shall be assumed by HiSoft effective as of the Effective Time. HiSoft shall take such actions as are necessary for the assumption and conversion of the VanceInfo Options and VanceInfo RSUs pursuant to this Section 2.2.

Section 2.3 Exchange Fund.

(a) Subject to the conditions and terms of the depositary agreement dated as of December 11, 2007, entered into among VanceInfo, JPMorgan Chase Bank, N.A., as depositary (the “VanceInfo Depositary”), and all holders from time to time of VanceInfo ADSs (the “VanceInfo Deposit Agreement”), prior to the Effective Time, HiSoft shall, subject to VanceInfo’s prior approval (which approval shall not be unreasonably withheld, conditioned or delayed), appoint a commercial bank or trust to act as exchange agent hereunder for the purpose of cancelling VanceInfo Shares and VanceInfo ADSs in exchange for the Per Share Merger Consideration and the Per ADS Merger Consideration, as applicable (the “Exchange Agent”).

(b) Prior to the Effective Time, HiSoft shall deposit, allot and issue or cause to be deposited, allotted and issued, as the case may be, with the Exchange Agent, a number of HiSoft Shares and HiSoft ADSs sufficient to settle the Merger Consideration in accordance with this Article II. The HiSoft ADSs shall be issued in accordance with the depositary agreement dated as of June 29, 2010 entered into among HiSoft, Deutsche Bank Trust Company Americas, as depositary (the “HiSoft Depositary”), and all holders from time to time of the HiSoft ADSs (the “HiSoft Deposit Agreement”), and HiSoft shall cause the HiSoft Depositary to issue the Per ADS Merger Consideration to the Exchange Agent.

Section 2.4 Exchange Procedures.

(a) Holders of VanceInfo Shares. (i) Promptly after the Effective Time (and in any event within five business days thereafter), the Surviving Corporation shall cause the Exchange Agent to mail to each registered holder of VanceInfo Shares (other than the VanceInfo Depositary and holders of Excluded Shares) (i) a form of letter of transmittal (which shall specify the manner in which delivery of the Per Share Merger Consideration to the registered holders of VanceInfo Shares shall be effected) and (ii) instructions for effecting the surrender of any and all share certificates which have been issued representing VanceInfo Shares (the “Certificates”). Each registered holder of VanceInfo Shares (including VanceInfo Shares not represented by a Certificate (“Uncertificated Shares”)) shall be entitled to receive the applicable Per Share Merger Consideration, without interest, for each VanceInfo Share (including VanceInfo Shares formerly represented by a Certificate and Uncertificated Shares) in exchange for the right to receive the applicable Per Share Merger Consideration at the Effective Time, provided that (A) each holder of a Certificate shall be required to surrender such Certificate (or a declaration of loss

or non-receipt and, if applicable, indemnity in the required form and in compliance with Section 2.8) to the Exchange Agent and the Certificate so surrendered shall forthwith be cancelled, and (B) each registered holder of VanceInfo Shares (including Uncertificated Shares) shall be required to submit to the Exchange Agent the letter of transmittal, duly executed and completed in accordance with the instructions thereto, and such other documents as may reasonably be required by the Exchange Agent.

Upon the Effective Time, the registered holder of any VanceInfo Shares shall have no further rights in respect of any VanceInfo Shares, and each Certificate in respect of such VanceInfo Shares shall be deemed at any time after the Effective Time to represent only the right to receive the Per Share Merger Consideration, without interest, as contemplated by this Article II.

The VanceInfo Depositary shall be entitled to receive the Per ADS Merger Consideration, without interest, for each VanceInfo Share held by the VanceInfo Depositary in respect of which a VanceInfo ADS has been issued (other than those VanceInfo ADSs reserved for future grants under the VanceInfo Share Incentive Plans) (the “Aggregate ADS Payment”), provided that the VanceInfo Depositary shall be required to surrender such Certificates it holds to the Exchange Agent, together with such letter of transmittal, duly executed and completed in accordance with the instructions thereto, and such other documents as may reasonably be required by the Exchange Agent, and the Certificates so surrendered shall forthwith be cancelled. Promptly after the payment of the Aggregate ADS Payment (and in any event within five business days thereafter), and subject to the VanceInfo Deposit Agreement, the Surviving Corporation and the Exchange Agent shall direct the VanceInfo Depositary to mail to each registered holder of VanceInfo ADSs (other than holders of Excluded Shares) (A) a form of letter of transmittal (which shall specify the manner in which delivery of the Per ADS Merger Consideration to the registered holders of VanceInfo ADSs shall be effected); and (B) instructions for effecting the surrender of any and all ADRs (as such term is defined in the VanceInfo Deposit Agreement) evidencing VanceInfo ADSs.

Each ADR in respect of such cancelled VanceInfo ADS shall be deemed at any time after the Effective Time to represent only the right to receive the Per ADS Merger Consideration, without interest, as contemplated by this Article II. Notwithstanding anything to the contrary set forth in this

Section 2.4(b), each registered holder of VanceInfo ADSs shall pay any applicable fees, charges and expenses provided under the VanceInfo Deposit Agreement and any and all Taxes under applicable Law in connection with distribution of the Per ADS Merger Consideration to VanceInfo ADS holders.

Section 2.5 Transfer Books; No Further Ownership Rights. Subject to Section 2.6, the Merger Consideration paid in respect of the cancellation of VanceInfo Shares and VanceInfo ADSs, respectively, in accordance with the terms of this Article II shall be deemed to have been paid in full satisfaction of all rights pertaining to VanceInfo Shares (including VanceInfo Shares previously represented by Certificates and Uncertificated Shares) or ADRs. At the Effective Time, the register of members of VanceInfo and the register of ADRs of VanceInfo shall be closed, and thereafter there shall be no further registration of transfers on such register of members or on such register of ADRs of any VanceInfo Shares or VanceInfo ADSs, respectively, that were issued and outstanding immediately prior to the Effective Time. From and after the Effective Time, (i) the holders of VanceInfo Shares issued and outstanding immediately prior to the Effective Time and (ii) subject to the VanceInfo Deposit Agreement, the holders of ADRs that evidenced ownership of VanceInfo ADSs outstanding immediately prior to the Effective Time, shall cease to have any rights with respect to such VanceInfo Shares or VanceInfo ADSs, except as otherwise provided for herein or by applicable Law. Subject to the last sentence of Section 2.6, if, at any time after the Effective Time, Certificates or ADRs are presented to the Surviving Corporation, or the VanceInfo Depositary, where applicable, for any reason, they shall be cancelled as provided in this Article II.

Section 2.6 Termination of Exchange Fund. Any portion of the Exchange Fund which remains undistributed at the date six months after the Effective Time shall be delivered to HiSoft and any holder of VanceInfo Share or ADRs that evidenced ownership of VanceInfo ADSs that were in each case issued and outstanding immediately prior to the Effective Time (other than the Excluded Shares) who has not theretofore complied with this Article II shall thereafter look only to HiSoft for the Per Share Merger Consideration or the Per ADS Merger Consideration, as the case may be, exchangeable for such VanceInfo Shares or such ADRs, as applicable, to which such holder is entitled, without any interest on any portion thereof. Any such portion of the Exchange Fund remaining unclaimed by such holders of VanceInfo Shares at such time at which amounts would otherwise escheat to or become property of any Governmental Entity shall, to the extent permitted by Law, become the property of HiSoft or its designee, free and clear of any claims or interest of any Person previously entitled thereto.

Section 2.7 No Liability. None of HiSoft, Merger Sub, VanceInfo, the Surviving Corporation or the Exchange Agent shall be liable to any Person in respect of any Merger Consideration from the Exchange Fund delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.

If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit or declaration of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by the Surviving Corporation or by the Exchange Agent, an indemnity or the posting by such Person of a bond in such reasonable amount as the Surviving Corporation or the Exchange Agent may direct as indemnity against any claim that may be made against it with respect to such lost, stolen or destroyed Certificate, the Exchange Agent will deliver in exchange for such lost, stolen or destroyed Certificate the applicable Per Share Merger Consideration with respect to VanceInfo Shares formerly represented thereby pursuant to this Agreement.

Section 2.9 Withholding Rights. Each of the Surviving Corporation, HiSoft, VanceInfo and the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement such amounts as it reasonably determines it is required to deduct and withhold with respect to the making of such payment under any provisions of Tax Law of the United States, the PRC, or other applicable jurisdictions. To the extent that amounts are so withheld and paid over to the appropriate Governmental Entity by the Surviving Corporation, HiSoft, VanceInfo or the Exchange Agent, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to (a) the holder of VanceInfo Shares or VanceInfo ADSs in respect of which such deduction and withholding was made by the Surviving Corporation, HiSoft or the Exchange Agent, as the case may be, (b) HiSoft in respect of which such deduction and withholding was made by VanceInfo with respect any Termination Fee paid by VanceInfo, and (c) VanceInfo in respect of which such deduction and withholding was made by HiSoft with respect to any Termination Fee paid by HiSoft.

(a) the representations and warranties of VanceInfo shall not be true and correct or VanceInfo shall have breached or failed to perform any of its covenants or agreements contained in this Agreement, which failure to be true and correct, breach or failure to perform (i) would result in the failure of a condition set forth in Section 7.2 and (ii) cannot be cured by the Termination Date, or if capable of being cured, shall not have been cured within 45 days following receipt by VanceInfo of written notice from HiSoft indicating such failure to be so true and correct or such breach or failure to perform and stating HiSoft’s intention to terminate this Agreement pursuant to this Section 8.3(a) as a result thereof (or, if earlier, the Termination Date); provided, that HiSoft shall not have the right to terminate this Agreement pursuant to this Section 8.3(a) if it is then in material breach of any representations, warranties, covenants or other agreements hereunder and such breach would result in any condition to Closing set forth in Section 7.3 not being satisfied;

(b) if (i) all of the conditions set forth in Section 7.1 and Section 7.2 (other than those conditions that by their nature are to be satisfied by actions taken at the Closing) have been satisfied, (ii) VanceInfo has confirmed by notice to HiSoft that all conditions set forth in Section 7.3 have been satisfied or that it is willing to waive any unsatisfied conditions in Section 7.3 and (iii) HiSoft or Merger Sub fail to consummate the Merger within three business days following the date the Closing should have occurred pursuant to Section 1.3; or

(i) This Agreement is terminated (A) by VanceInfo pursuant to Section 8.4(c), (B) by VanceInfo pursuant to Section 8.4(b), (C) by VanceInfo pursuant to Section 8.4(a) as a result of a willful and material breach by HiSoft of Section 6.2 or Section 6.3(b), or (D) except in circumstances covered by Section 8.5(c)(ii) below, by either VanceInfo or HiSoft pursuant to Section 8.2(d).

(e) The Parties expressly acknowledge and agree that, with respect to any termination of this Agreement under circumstances in which the Termination Fee is payable pursuant to this Section 8.5, payment of the Termination Fee, as required hereunder, shall constitute liquidated damages with respect to any claim for damages or any other claim which VanceInfo, on the one hand, or HiSoft, on the other hand, as the case may be, would otherwise be entitled to assert against HiSoft, on the one hand, or VanceInfo, on the other hand, as the case may be, or their respective assets, or against any of their respective employees or equity holders (without limiting any claims otherwise available to (i) VanceInfo against the applicable HiSoft Voting Shareholders pursuant to the applicable HiSoft Voting Agreements or (ii) HiSoft against the VanceInfo Voting Shareholders pursuant to the terms of the VanceInfo Voting Agreement) or any other HiSoft Related Party or VanceInfo Related Party, as the case may be, with respect to any such termination of this Agreement. The Parties expressly acknowledge and agree that, in light of the difficulty of accurately determining actual damages with respect to the foregoing upon any such termination of this Agreement under circumstances in which the Termination Fee is payable pursuant to this Section 8.5, the right to such payment (A) constitutes a reasonable estimate of the damages that will be suffered by reason of any such termination of this Agreement and is not a penalty, and (B) shall be the sole and exclusive remedy and in full and complete satisfaction of any and all damages arising as a result of any such termination of this Agreement; provided, however, that nothing in this Section 8.5(e) shall limit the rights of HiSoft, Merger Sub or VanceInfo under Section 9.8 prior to any termination of this Agreement. Upon the payment of the Termination Fee under circumstances in which the Termination Fee is payable pursuant to this Section 8.5, VanceInfo or HiSoft, as the case may be, shall not have any further liability or obligation relating to or arising out of this Agreement or the transactions contemplated by this Agreement.

(f) Each of the Parties acknowledges that the agreements contained in this Section 8.5 are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, the other Parties would not have entered into this Agreement.

Section 9.4 Governing Law; Jurisdiction; Waiver of Jury Trial.

(a) This Agreement shall be construed, performed and enforced in accordance with the Laws of the State of New York without giving effect to its principles or rules of conflict of laws to the extent such principles or rules would require or permit the application of the Laws of another jurisdiction other than the State of New York, except that the following matters arising out of or relating to this Agreement shall be construed, performed and enforced in accordance with the Laws of the Cayman Islands in respect of which the Parties hereby irrevocably submit to the non-exclusive jurisdiction of the courts of the Cayman Islands: the Merger, the vesting of the rights, property, choses in action, business, undertaking, goodwill, benefits, immunities and privileges, contracts, obligations, claims, debts and liabilities of the Merger Sub in VanceInfo, the cancellation of VanceInfo Shares in consideration of the issue of HiSoft Shares, the fiduciary or other duties of the VanceInfo Board and the HiSoft Board; and the internal corporate affairs of VanceInfo and HiSoft. Except as provided in the prior sentence, any Proceeding (whether sounding in contract, tort, equity or otherwise) arising out of or relating to this Agreement, the other Transaction Agreements or the transactions contemplated hereby or thereby, including any Proceeding against any VanceInfo Related Party or HiSoft Related Party, shall be brought solely and exclusively in any New York State court or Federal court of the United States of America sitting in the County of New York in the State of New York. Each of the Parties agrees that a final judgment (subject to any appeals therefrom) in any such Proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law. Each Party hereby irrevocably submits to the exclusive jurisdiction of such courts in respect of any such Proceeding, and hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any such Proceeding in any such court in accordance with the provisions of this Section 9.4(a). Each of the Parties hereby irrevocably waives, to the fullest extent permitted by Law, the defense of an inconvenient forum to the maintenance of such Proceeding in any such court. Each of the Parties hereby irrevocably and unconditionally consents to service of process in the manner provided for notices in Section 9.3. Nothing in this Agreement or any of the other Transaction Agreements will affect the right of any Party to this Agreement to serve process in any other manner permitted by Law. The consent to jurisdiction set forth in this Section 9.4 shall not constitute a general consent to service of process in the State of New York and shall have no

effect for any purpose except as provided in this Section. The Parties agree that a final judgment in any such suit, action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.

(b) EACH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE OTHER TRANSACTION AGREEMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. Each Party certifies and acknowledges that (i) no representative, agent or attorney of any other Party has represented, expressly or otherwise, that such other Party would not, in the event of a Proceeding, seek to enforce the foregoing waiver, (ii) each Party understands and has considered the implications of this waiver, (iii) each Party makes this waiver voluntarily, and (iv) each Party has been induced to enter into this Agreement by, among other things, the mutual waivers and certifications in this Section 9.4(b).

Section 9.5 Descriptive Headings. The descriptive headings herein are inserted for convenience of reference only and are not intended to be part of or to affect the meaning or interpretation of this Agreement.

Section 9.6 No Third Party Beneficiaries. Except as expressly set forth in Section 6.6, this Agreement shall be binding upon and inure solely to the benefit of each Party hereto and its successors and permitted assigns, and nothing in this Agreement, express or implied, is intended to or shall confer upon any other person any rights, benefits or remedies of any nature whatsoever under or by reason of this Agreement. The rights granted under this Agreement to VanceInfo shall be enforceable solely by VanceInfo in its sole and absolute discretion (and VanceInfo shall have the sole right to enforce any such rights and pursue any damages or other relief related to this Agreement or any of the transactions contemplated hereby on behalf of holders of VanceInfo Shares and VanceInfo ADSs), and the rights granted under this Agreement to HiSoft shall be enforceable solely by HiSoft in its sole and absolute discretion (and HiSoft shall have the sole right to enforce any such rights and pursue any damages or other relief related to this Agreement or any of the transactions contemplated hereby on behalf of holders of HiSoft Shares and HiSoft ADSs).

Section 9.7 Severability. The provisions of this Agreement shall be deemed severable and the invalidity or unenforceability of any provision shall not affect the validity or enforceability of the other provisions hereof. If any provision of this Agreement, or the application thereof to any person or any circumstance, is invalid or unenforceable, (a) a suitable and equitable provision shall be substituted therefor in order to carry out, so far as may be valid and enforceable, the intent and purpose of such invalid or unenforceable provision and (b) the remainder of this Agreement and the application of such provision to other persons or circumstances shall not be affected by such invalidity or unenforceability, nor shall such invalidity or unenforceability affect the validity or enforceability of such provision, or the application thereof, in any other jurisdiction.

Section 9.8 Specific Performance. Each of the Parties acknowledges and agrees that, in the event of any breach of, or any failure to perform, any specific provision of this Agreement prior to or at the Effective Time, the non-breaching party would be irreparably and immediately harmed and could not be made whole by monetary damages. It is accordingly agreed that each of the Parties shall (i) be entitled, in addition to any other remedy to which it may be entitled at law or in equity, to compel specific performance of any specific provision of this Agreement or to obtain injunctive relief to prevent breaches of any specific provision of this Agreement, (ii) waive, in any action against it for specific performance or injunctive relief, the defense of the adequacy of a remedy at law, and (iii) waive any requirement for the

securing or posting of any bond in connection with the obtaining of any such specific performance or injunctive relief. For the avoidance of doubt, each of Parties shall be entitled to enforce specifically the terms and provisions of this Agreement to prevent breaches of or enforce compliance with all the agreements and covenants contained in this agreement, including those agreements and covenants of the other Party or Parties that require the other Party or Parties to (x) use its or their reasonable best efforts to cause the Closing to occur as soon as practicable and (y) effect the Merger. A Party’s pursuit of specific performance or injunctive relief at any time shall not be deemed an election of remedies or waiver of the right to pursue any other right or remedy to which such Party may be entitled, including the right to pursue remedies for liabilities or damages incurred or suffered by such Party in the case of a breach of this Agreement.

Section 9.9 Amendment. This Agreement may be amended by action taken by VanceInfo, HiSoft and Merger Sub at any time before or after approval of the Merger by the earlier of the Required VanceInfo Vote or the Required HiSoft Vote but, after any such approval, no amendment shall be made which requires the approval of such shareholders under applicable Law without such approval. This Agreement may not be amended except by an instrument in writing signed on behalf of the Parties.

Section 9.10 Extension; Waiver. At any time prior to the Effective Time, each Party hereto (for these purposes, HiSoft and Merger Sub shall together be deemed one Party and VanceInfo shall be deemed the other Party) may (a) extend the time for the performance of any of the obligations or other acts of the other Party, (b) waive any inaccuracies in the representations and warranties of the other Party contained herein or in any document, certificate or writing delivered pursuant hereto, or (c) waive compliance by the other Party with any of the agreements or conditions contained herein. Any agreement on the part of either Party hereto to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such Party. The failure of either Party hereto to assert any of its rights hereunder shall not constitute a waiver of such rights.

Section 9.11 Interpretation.
