Ladies and Gentlemen:

HiSoft Technology International Limited, a company established in the Cayman Islands (the “Company”), and the shareholders of the Company listed in Schedule II hereto (the “Selling Shareholders”) propose to sell to the several underwriters (the “Underwriters”) named in Schedule I hereto for whom Deutsche Bank Securities Inc. (“Deutsche Bank”), UBS AG (“UBS”) and Citigroup Global Markets Inc. are acting as representatives (the “Representatives”) an aggregate of 5,000,000 American depositary shares (“ADSs”) of the Company (the “Firm ADSs”), each representing 19 common shares, par value $0.0001 per share (each a “Common Share”), of which 500,000 ADSs will be sold by the Company and 4,500,000 ADSs will be sold by the Selling Shareholders. The respective numbers of the Firm ADSs to be so purchased from the Company and the Selling Shareholders by the several Underwriters are set forth opposite the Underwriters’ names in Schedule I hereto, and the respective numbers to be sold by the Selling Shareholders are set forth opposite their names in Schedule II hereto. The Selling Shareholders listed in Schedule III hereto also propose to sell at the Underwriters’ option an aggregate of up to 750,000 additional ADSs (the “Option ADSs”) as set forth below. The Firm ADSs and the

Option ADSs are herein collectively called the “Offered ADSs.” The Common Shares represented by the Firm ADSs are hereinafter called the “Firm Shares,” the Common Shares represented by the Option ADSs are hereinafter called the “Option Shares,” and the Firm Shares and Option Shares are hereinafter collectively called the “Shares.” Unless the context otherwise requires, each reference to the Firm ADSs, the Option ADSs or the Offered ADSs herein also includes the Shares.

As the Representatives, you have advised the Company and the Selling Shareholders (a) that you are authorized to enter into this Agreement on behalf of the several Underwriters, and (b) that the several Underwriters are willing, acting severally and not jointly, to purchase the numbers of Firm ADSs set forth opposite their respective names in Schedule I, plus their pro rata portion of the Option ADSs if you elect to exercise the over-allotment option in whole or in part for the accounts of the several Underwriters.

In consideration of the mutual agreements contained herein and of the interests of the parties in the transactions contemplated hereby, the parties hereto agree as follows:

(a) The Company represents and warrants to each of the Underwriters as follows:

(i) A registration statement on Form F-1 (File No. 333-170752) with respect to the Shares underlying the Offered ADSs has been prepared by the Company in conformity in all material respects with the requirements of the Securities Act of 1933, as amended (the “Act”), and the rules and regulations (the “Rules and Regulations”) of the Securities and Exchange Commission (the “Commission”) thereunder and has been filed with the Commission. The Company and the transactions contemplated by this Agreement meet the requirements and comply with the conditions for the use of Form F-1. Copies of such registration statement, including any amendments thereto, the preliminary prospectuses (meeting in all material respects the requirements of the Rules and Regulations) contained therein and the exhibits, financial statements and schedules, as finally amended and revised, have heretofore been delivered by the Company to you. Such registration statement, as amended at the time it became effective, together with any registration statement filed by the Company pursuant to Rule 462(b) under the Act, is herein referred to as the “Registration Statement,” which shall be deemed to include all information omitted therefrom in reliance upon Rule 430A under the Act and contained in the Prospectus referred to below, has become effective under the Act and no post-effective amendment to the Registration Statement has been filed as of the date of this Agreement. “Prospectus” means the form of prospectus first filed with the Commission pursuant to and within the time limits described in Rule 424(b) under the Act. Each preliminary prospectus included in the Registration Statement prior to the time it becomes effective is herein referred to as a “Preliminary Prospectus.”

(ii) As of the Applicable Time (as defined below) and as of the Closing Date or the Option Closing Date (as defined below), as the case may be, neither (i) the General Use Free Writing Prospectus(es) (as defined below) issued at or prior to the Applicable Time, the Statutory Prospectus (as defined below) and the information included on Schedule IV hereto, all considered together (collectively, the “General Disclosure Package”), nor (ii) any individual Limited Use Free Writing Prospectus (as defined below), when considered together with the General Disclosure Package, included or will include any untrue statement of a material fact or

Each of the subsidiaries of the Company and the affiliated entity (collectively, the “Subsidiaries”) as listed in Exhibit A hereto has been duly organized and is validly existing as a corporation in good standing under the laws of the jurisdiction of its incorporation, with corporate power and authority to own or lease its properties and conduct its business as described in the Registration Statement, the General Disclosure Package and the Prospectus. The Subsidiaries are the only operating entities, direct or indirect, of the Company. The Company and each of its Subsidiaries are duly qualified to transact business in all jurisdictions in which the conduct of their business requires such qualification, except for such jurisdictions where the failure to so qualify would not (i) have a material adverse effect on the earnings, business, management, properties, assets, rights, operations, condition (financial or otherwise) or prospects of the Company and of the Subsidiaries taken as a whole or (ii) prevent the consummation of the transactions contemplated hereby (the occurrence of any such effect or any such prevention described in the foregoing clauses (i) and (ii) being referred to as a “Material Adverse Effect”). The outstanding share capital of each of the Subsidiaries (i) has been duly authorized and validly issued, (ii) is fully paid and non-assessable in accordance with the relevant laws of the People’s Republic of China (excluding the Hong Kong Special Administrative Region, the Macao Special Administrative Region and Taiwan solely for the purpose of this Agreement, the “PRC”), and (iii) to the extent shown in Exhibit A hereto, is owned by the Company or another Subsidiary free and clear of all liens, encumbrances and equities and claims; and except as described in the Registration Statement, the General

Upon the sale and delivery to the Underwriters of the Offered ADSs, and payment therefor, pursuant to this Agreement, the Underwriters will acquire good, marketable and valid title to such Offered ADSs, free and clear of all pledges, liens, security interests, charges, claims or encumbrances of any kind. Neither the filing of the Registration Statement or the ADS Registration Statement (as defined below), nor the offering or sale of the Offered ADSs and the Shares as contemplated by this Agreement gives rise to any rights, other than those which have been waived or satisfied, for or relating to the registration of any Shares.

further amendments thereto will conform, in all material respects to the requirements of the Exchange Act and the rules and regulations of the Commission thereunder, and did not and will not, as of the applicable effective date, contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading.

(viii) Except as disclosed in the Registration Statement, the General Disclosure Package and the Prospectus, there are no contracts, agreements or understandings between the Company and any person granting such person the right to require the Company to file a registration statement under the Act with respect to any securities of the Company owned or to be owned by such person or to require the Company to include such securities in the securities registered pursuant to the Registration Statement, the ADS Registration Statement or in any securities being registered pursuant to any other registration statement filed by the Company under the Act.

(ix) The Commission has not issued an order preventing or suspending the use of any Preliminary Prospectus, any Issuer Free Writing Prospectus or the Prospectus relating to the proposed offering of the Offered ADSs, and no proceeding for that purpose or pursuant to Section 8A of the Act has been instituted or, to the Company’s knowledge, threatened by the Commission. The Registration Statement contains, and the Prospectus and any amendments or supplements thereto will contain, all statements which are required to be stated therein by, and will conform in all material respects to, the requirements of the Act and the Rules and Regulations.

reliance upon, and in conformity with, written information furnished to the Company by or on behalf of any Underwriter through the Representatives, specifically for use therein, it being understood and agreed that the only such information is that described in Section 13 herein.

(x) Each Issuer Free Writing Prospectus, as of its issue date and at all subsequent times through the completion of the public offer and sale of the Offered ADSs or until any earlier date that the Company notified or notifies the Representatives, did not, does not and will not include any information that conflicted, conflicts or will conflict with the information contained in the Registration Statement or the Prospectus.

The execution and delivery of this Agreement and the Deposit Agreement, the consummation of the transactions herein and therein contemplated and the fulfillment of the terms hereof and thereof will not conflict with or result in a breach of (x) any of the terms or provisions of, or constitute a default under, any indenture, mortgage, deed of trust or other agreement or instrument to which the Company or any Subsidiary is a party or by which the Company or any Subsidiary or any of their respective properties is bound, except for such conflicts, breaches or defaults that would not, individually or in the aggregate, have a Material Adverse Effect, (y) the memorandum and articles of association, certificate or articles of incorporation, by-laws or other organizational documents of the Company or any Subsidiary or (z) any applicable law.

(xxxi) Neither the Company, nor to the Company’s knowledge, any of its affiliates, has taken or may take, directly or indirectly, any action designed to cause or result in, or which has constituted or which might reasonably be expected to constitute, the stabilization or manipulation of the price of any securities of the Company to facilitate the sale or resale of the Offered ADSs or Shares. The Company acknowledges that the Underwriters may engage in passive market making transactions in the Offered ADSs or Shares on the Nasdaq Global Market in accordance with Regulation M under the Exchange Act.

(xxxii) The Company is not and, after giving effect to the offering and sale of the Offered ADSs contemplated hereunder and the application of the net proceeds from such sale as described in the Registration Statement, the General Disclosure Package and the Prospectus, will not be an “investment company” within the meaning of such term under the Investment Company Act of 1940, as amended (the “1940 Act”), and the rules and regulations of the Commission thereunder.

2. Purchase, Sale and Delivery of the Firm ADSs.

(a) On the basis of the representations, warranties and covenants herein contained, and subject to the conditions herein set forth, the Company agrees to sell to the Underwriter 9,500,000 Firm Shares and each of the Selling Shareholders, severally and not jointly, agrees to sell to the Underwriters the number of Firm Shares set forth opposite the name of such Selling Shareholder in Schedule II hereof, and each Underwriter agrees, severally and not jointly, to purchase, at a price of $[•] per ADS, the number of Firm ADSs set forth opposite the name of each Underwriter in Schedule I hereof, subject in each case to adjustments in accordance with Section 9 hereof. The number of Firm Shares to be purchased by each Underwriter from each Selling Shareholder shall be as nearly as practicable in the same proportion to the total number of Firm Shares being sold by each Selling Shareholder as the number of Firm Shares being purchased by each Underwriter bears to the total number of Firm Shares to be sold hereunder. The obligations of the Company and of each of the Selling Shareholders shall be several and not joint.

(b) Certificates in negotiable form for the total number of the Shares to be sold hereunder by the Selling Shareholders have been placed in custody with the Company as custodian (the “Custodian”) pursuant to the custody agreement executed by each Selling Shareholder (such Selling Shareholder’s “Custody Agreement”) for delivery of all Firm Shares and any Option Shares to be sold hereunder by the Selling Shareholders. Each of the Selling

Shareholders, severally and not jointly, specifically agrees that the Firm Shares and any Option Shares represented by the certificates held in custody for such Selling Shareholder under the Custody Agreement are subject to the interests of the Underwriters hereunder, that the arrangements made by such Selling Shareholder for such custody are to that extent irrevocable, and that the obligations of such Selling Shareholder thereunder shall not be terminable by any act or deed of such Selling Shareholder (or by any other person, firm or corporation including the Company, the Custodian or the Underwriters) or by operation of law (including the dissolution of a Selling Shareholder) or by the occurrence of any other event or events, except as set forth in the Custody Agreement. If any such event should occur prior to the delivery to the Underwriters of the Firm Shares or the Option Shares hereunder, certificates for the Firm Shares or the Option Shares, as the case may be, shall be delivered by the Custodian in accordance with the terms and conditions of this Agreement and the respective Custody Agreement as if such event has not occurred. The Custodian is authorized to receive and acknowledge receipt of the proceeds of sale of the Shares held by it against delivery of such Shares.

(c) Payment for the Firm ADSs to be sold hereunder is to be made in Federal (same day) funds to an account designated by the Company for the ADSs to be sold by it and to an account designated by the Custodian for the ADSs to be sold by the Selling Shareholders, in each case, against delivery of certificates therefor to the Representatives for the several accounts of the Underwriters. Such payment and delivery are to be made through the facilities of The Depository Trust Company, at 10:00 a.m., New York City Time, on the third business day after the date of this Agreement or at such other time and date not later than five business days thereafter as you and the Company shall agree upon, such time and date being herein referred to as the “Closing Date.” As used herein, “business day” means a day on which the Nasdaq Global Market is open for trading and on which banks in New York are open for business and not permitted by law or executive order to be closed.

(d) In addition, on the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, each of the Selling Shareholders listed on Schedule III hereto, severally and not jointly, hereby grants an option to the several Underwriters to purchase up to the number of Option ADSs set forth opposite the name of such Selling Shareholder, as applicable, in Schedule III hereof at the price per ADS as set forth in clause (a) of this Section 2. The option granted hereby may be exercised in whole or in part by giving written notice (i) at any time before the Closing Date and (ii) at any time, from time to time thereafter within 30 days after the date of this Agreement, by you, as the Representatives of the several Underwriters, to the Attorney in Fact (as defined in such Selling Shareholder’s Power of Attorney) and the Custodian setting forth the number of Option ADSs as to which the several Underwriters are exercising the option and the time and date at which such certificates are to be delivered. If the option granted hereby is exercised in part, the respective number of Option ADSs to be sold by each of the Selling Shareholders listed in Schedule III hereto shall be determined on a pro rata basis in accordance with the percentages set forth opposite their names on Schedule III hereto. The time and date at which certificates for Option Shares are to be delivered shall be determined by the Representatives but shall not be earlier than three nor later than 10 full business days after the exercise of such option, nor in any event prior to the Closing Date (such time and date being herein referred to as the “Option Closing Date”). If the date of exercise of the option is three or more days before the Closing Date, the notice of exercise shall set the Closing Date as the Option Closing Date. The number of Option ADSs to be

purchased by each Underwriter shall be in the same proportion to the total number of Option ADSs being purchased as the number of Firm ADSs being purchased by such Underwriter bears to the total number of Firm ADSs, adjusted by you in such manner as to avoid fractional ADSs. The option with respect to the Option ADSs granted hereunder may be exercised only to cover over-allotments in the sale of the Firm ADSs by the Underwriters. You, as the Representatives of the several Underwriters, may cancel such option at any time prior to its expiration by giving written notice of such cancellation to the Company and the Selling Shareholders listed in Schedule III hereto. To the extent, if any, that the option is exercised, payment for the Option ADSs shall be made on the Option Closing Date in Federal (same day) funds drawn to the order of the Attorney in Fact and the Custodian for the Option ADSs to be sold by the Selling Shareholders listed in Schedule III hereto against delivery of certificates therefor through the facilities of The Depository Trust Company, New York, New York.

The Representatives may from time to time thereafter change the public offering price and other selling terms.

The Company will deliver to the Representatives at or before the Closing Date, conformed copies of the Registration Statement and all amendments thereto including all exhibits filed therewith, and will deliver to the Representatives such number of copies of the Registration Statement (including such number of copies of the exhibits filed therewith that may reasonably be requested), and of all amendments thereto, as the Representatives may reasonably request.

(vi) The Company will comply with the Act and the Rules and Regulations, and the Exchange Act, and the rules and regulations of the Commission thereunder, so as to permit the completion of the distribution of the Offered ADSs as contemplated in this Agreement and the Prospectus. If during the period in which a prospectus (or, in lieu thereof, the notice referred to under Rule 173(a) under the Act) is required by law to be delivered by

an Underwriter or dealer, any event shall occur as a result of which, in the judgment of the Company or in the reasonable opinion of the Underwriters, it becomes necessary to amend or supplement the Prospectus in order to make the statements therein, in the light of the circumstances existing at the time the Prospectus is delivered to a purchaser, not misleading, or, if it is necessary at any time to amend or supplement the Prospectus to comply with the Act and the Rules and Regulations, and the Exchange Act, and the rules and regulations of the Commission thereunder, the Company will promptly prepare and file with the Commission an appropriate amendment to the Registration Statement or supplement to the Prospectus so that the Prospectus as so amended or supplemented will not, in the light of the circumstances when it is so delivered, be misleading, or so that the Prospectus will comply with the Act and the Rules and Regulations, and the Exchange Act, and the rules and regulations of the Commission thereunder.

(vii) If the General Disclosure Package is being used to solicit offers to buy the Offered ADSs at a time when the Prospectus is not yet available to prospective purchasers and any event shall occur as a result of which, in the judgment of the Company or in the reasonable opinion of the Underwriters, it becomes necessary to amend or supplement the General Disclosure Package in order to make the statements therein, in the light of the circumstances, not misleading, or to make the statements therein not conflict with the information contained in the Registration Statement then on file, or if it is necessary at any time to amend or supplement the General Disclosure Package to comply with the Act and the Rules and Regulations, and the Exchange Act, and the rules and regulations of the Commission thereunder, the Company will promptly prepare, file with the Commission (if required) and furnish to the Underwriters and any dealers an appropriate amendment or supplement to the General Disclosure Package.

(ix) The Company will make generally available to its security holders, as soon as it is practicable to do so, but in any event not later than 15 months after the effective date of the Registration Statement, an earnings statement (which need not be audited) in reasonable detail, covering a period of at least 12 consecutive months beginning after the effective date of the Registration Statement, which earnings statement shall satisfy the requirements of Section 11(a) of the Act and Rule 158 under the Act and will advise you in writing when such statement has been so made available.

(x) During the period of five years hereafter, the Company will furnish to the Representatives and, upon request, to each of the other Underwriters, as soon as practicable after the end of each fiscal year, a copy of its annual report for such year; and the Company will furnish to the Representatives (i) as soon as available, a copy of each report of the Company filed with the Commission under the Exchange Act or mailed to stockholders; and (ii) from time to time, such other information concerning the Company as the Representatives may reasonably request. However, so long as the Company is subject to the reporting requirements of either Section 13 or Section 15(d) of the Exchange Act and is

timely filing reports with the Commission on its Electronic Data Gathering, Analysis and Retrieval system, it is not required to furnish such reports or statements to the Underwriters.

(xi) Prior to the Closing Date, the Company will furnish to the Underwriters, as soon as they have been prepared by or are available to the Company, a copy of any unaudited interim financial statements of the Company for any period subsequent to the period covered by the most recent financial statements appearing in the Registration Statement, the General Disclosure Package and the Prospectus.

(xii) No offering, sale, short sale or other disposition of Common Shares or ADSs of the Company or other securities convertible into or exchangeable or exercisable for Common Shares or ADSs or derivative of Common Shares underlying ADSs (or agreement for such) will be made for a period of 90 days after the date of the Prospectus, directly or indirectly, by the Company otherwise than hereunder or with the prior written consent of the Representatives; provided, however, that the Company may (i) grant employee stock options and nonvested common shares pursuant to the terms of any stock option or similar equity incentive or compensation plan approved by the board of directors and shareholders of the Company, which is in effect at the Applicable Time, (ii) issue and sell Shares upon the exercise of such employee stock options, and (iii) offer, issue and transfer Common Shares or ADSs of the Company or securities convertible or exercisable for Common Shares or ADSs of the Company (collectively, the “M&A Shares”) in connection with the merger and/or acquisition of another company or the business or assets of another company, provided however that such M&A Shares shall not exceed 5% of the overall share capital of the Company outstanding as of the date of this Agreement, and provided further that it shall be a condition precedent to the transfer of any M&A Shares that the transferee execute an agreement stating that the transferee is receiving and holding the M&A Shares subject to restrictions set forth in Exhibit C hereto. Notwithstanding the foregoing, if (1) during the last 17 days of the 90-day restricted period, the Company issues an earnings release or material news or a material event relating to the Company occurs; or (2) prior to the expiration of the 90-day restricted period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the 90-day restricted period, then in each case the restrictions imposed by this Agreement shall continue to apply until the expiration of the 18-day period beginning on the date of the release of the earnings results or the occurrence of material news or a material event relating to the Company, as the case may be, unless the Representatives waive, in writing, such extension.

(xiii) The Company will use its best efforts to list the Offered ADSs on the Nasdaq Global Market and maintain the listing of the Offered ADSs on the Nasdaq Global Market.

(xiv) The Company shall apply the net proceeds of its sale of the Offered ADSs as set forth in the Registration Statement, the General Disclosure Package and the Prospectus and shall file such reports with the Commission with respect to the sale of the Offered ADSs and the application of the proceeds therefrom as may be required in accordance with Rule 463 under the Act.

(xv) The Company shall not invest, or otherwise use the proceeds received by the Company from its sale of the Offered ADSs in such a manner as would require the Company or any of the Subsidiaries to register as an investment company under the 1940 Act.

(xvi) The Company will indemnify and hold harmless the Underwriters against any documentary, stamp or similar issue tax, including any interest and penalties, on the creation, issue and sale of the Offered ADSs and on the execution and delivery of this Agreement.

(xviii) The Company will not take, directly or indirectly, any action designed to cause or result in, or that has constituted or might reasonably be expected to constitute, the stabilization or manipulation of the price of any securities of the Company.

(b) Each of the Selling Shareholders, severally and not jointly, covenants and agrees with the several Underwriters that:

(i) In order to facilitate the Underwriters’ documentation of their respective compliance with the reporting and withholding provisions of the Tax Equity and Fiscal Responsibility Act of 1982 and the Interest and Dividend Tax Compliance Act of 1983 with respect to the transactions herein contemplated, such Selling Shareholder will deliver to you prior to or at the Closing Date a properly completed and executed United States Treasury Department Form W-8 or W-9 (or other applicable form or statement specified by Treasury Department regulations in lieu thereof).

(ii) Such Selling Shareholder will not take, directly or indirectly, any action designed to cause or result in, or that has constituted or might reasonably be expected to constitute, the stabilization or manipulation of the price of any securities of the Company.

(iii) Such Selling Shareholder agrees that it will not prepare or have prepared on its behalf or use or refer to, any “free writing prospectus” (as defined in Rule 405 under the Act), and agrees that it will not distribute any written materials in connection with the offer or sale of the ADSs.

(iv) During the Prospectus Delivery Period, such Selling Shareholder will advise the Representatives promptly, and will confirm such advice in writing to the Representatives, of any material change in the information relating to such Selling Shareholder in the Registration Statement, the Prospectus or any document comprising the General Disclosure Package.

(b) Each Selling Shareholder, severally and not jointly, agrees to indemnify each Underwriter, each Underwriter’s directors and officers and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, against any losses, claims, damages or liabilities to which such Underwriter or controlling person may become subject under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the General Disclosure Package or the Prospectus, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein any material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, the General Disclosure Package or the Prospectus or any such amendment or supplement in reliance upon and in conformity with written information pertaining to such Selling Shareholder furnished to the Company by such Selling Shareholder expressly for inclusion therein.

(c) Each Underwriter severally and not jointly will indemnify and hold harmless the Company, each of its directors, each of its officers who have signed the Registration Statement, the Selling Shareholders, and each person, if any, who controls the Company or the Selling Shareholders within the meaning of the Act, against any losses, claims, damages or liabilities to which the Company or any such director, officer, Selling Shareholder or controlling person may become subject under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, the ADS Registration Statement, the Form 8-A Registration Statement, any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Prospectus or any amendment or supplement thereto, (ii) with respect to the Registration Statement the ADS Registration Statement, the Form 8-A Registration Statement, or any amendment or supplement thereto, the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading or (iii) with respect to any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Prospectus or any amendment or supplement thereto, the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances under which

This indemnity agreement will be in addition to any liability which such Underwriter may otherwise have.

(d) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to this Section 8, such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing. No indemnification provided for in Section 8(a), (b) or (c) shall be available to any party who shall fail to give notice as provided in this Section 8(d) if the party to whom notice was not given was unaware of the proceeding to which such notice would have related and was materially prejudiced by the failure to give such notice, but the failure to give such notice shall not relieve the indemnifying party or parties from any liability which it or they may have to the indemnified party for contribution or otherwise than on account of the provisions of Section 8(a), (b) or (c). In case any such proceeding shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party and shall pay as incurred the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel at its own expense. Notwithstanding the foregoing, the indemnifying party shall pay as incurred (or within 30 days of presentation) the fees and expenses of the counsel retained by the indemnified party in the event (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them or (iii) the indemnifying party shall have failed to assume the defense and employ counsel reasonably acceptable to the indemnified party within a reasonable period of time after notice of commencement of the action. Such firm shall be designated in writing by you in the case of parties indemnified pursuant to Section 8(a) or (b) and by the Company and the Selling Shareholder in the case of parties indemnified pursuant to Section 8(c). The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. In addition, the indemnifying party will not, without the prior written consent of the indemnified party, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding of which indemnification may be sought hereunder (whether or not any

indemnified party is an actual or potential party to such claim, action or proceeding) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action or proceeding.

(e) To the extent the indemnification provided for in this Section 8 is unavailable to or insufficient to hold harmless an indemnified party under Section 8(a), (b) or (c) above in respect of any losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Shareholders on the one hand and the Underwriters on the other from the offering of the Offered ADSs. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company and the Selling Shareholders on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions or proceedings in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company and the Selling Shareholders on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total proceeds (after deducting underwriting commissions, but before taxes and other expenses payable by such Selling Shareholder) received by the Company and the Selling Shareholders from the Underwriters in the offering, as the case may be, bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Selling Shareholders on the one hand or the Underwriters on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company, the Selling Shareholders and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 8(e) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 8(e). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to above in this Section 8(e) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8(e), (i) no Underwriter shall be required to contribute any amount in excess of the underwriting discounts and commissions applicable to the Offered ADSs purchased by such Underwriter, (ii) no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation, and (iii) no Selling Shareholder shall be required to contribute any amount in excess of the total proceeds (after deducting underwriting commissions, but before taxes and other expenses payable by such Selling Shareholder) received by such Selling Shareholder from the Underwriters in the offering. The Underwriters’ obligations in this Section 8(e) to contribute are several in

proportion to their respective underwriting obligations and not joint. The Selling Shareholders’ obligations in this Section 8(e) to contribute are several in proportion to the number of Shares sold by each Selling Shareholder pursuant to this Agreement and not joint. No party shall be liable for contribution under this Section 8(e) except to the extent and under such circumstances as such party would have been liable for indemnification under this Section 8 if such indemnification were available or enforceable under applicable law.

(f) In any proceeding relating to the Registration Statement, any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Prospectus or any supplement or amendment thereto, each party against whom contribution may be sought under this Section 8 hereby consents to the jurisdiction of any court having jurisdiction over any other contributing party, agrees that process issuing from such court may be served upon it by any other contributing party and consents to the service of such process and agrees that any other contributing party may join it as an additional defendant in any such proceeding in which such other contributing party is a party. Notwithstanding the foregoing, the parties acknowledge and agree that no provision of this Agreement in any way constitutes or implies a waiver, termination or modification by International Finance Corporation of any privilege, immunity or exemption of International Finance Corporation granted in the Articles of Agreement establishing International Finance Corporation, international conventions or applicable law.

(g) Any losses, claims, damages, liabilities or expenses for which an indemnified party is entitled to indemnification or contribution under this Section 8 shall be paid by the indemnifying party to the indemnified party as such losses, claims, damages, liabilities or expenses are incurred.

9. Default by Underwriters.

If on the Closing Date or the Option Closing Date, as the case may be, any Underwriter shall fail to purchase and pay for the portion of the Offered ADSs which such Underwriter has agreed to purchase and pay for on such date (otherwise than by reason of any default on the part of the Company or a Selling Shareholder), you, as Representatives of the Underwriters, shall use your reasonable efforts to procure within 36 hours thereafter one or more of the other Underwriters, or any others, to purchase from the Company such amounts as may be agreed upon and upon the terms set forth herein, the Offered ADSs which the defaulting Underwriter or Underwriters failed to purchase. If during such 36 hours you, as such Representatives, shall not have procured such other Underwriters, or any others, to purchase the Offered ADSs agreed to be purchased by the defaulting Underwriter or Underwriters, then (a) if the aggregate number of ADSs with respect to which such default shall occur does not exceed 10% of the Offered ADSs to be purchased on the Closing Date or the Option Closing Date, as the case may be, the other Underwriters shall be obligated, severally, in proportion to the respective numbers of Offered ADSs which they are obligated to purchase hereunder, to purchase the Offered ADSs which such defaulting Underwriter or Underwriters failed to purchase, or (b) if the aggregate number of ADSs with respect to which such default shall occur exceeds 10% of the Offered ADSs to be purchased on the Closing Date or the Option Closing Date, as the case may be, the Company and the Selling Shareholders or you, as the Representatives of the Underwriters, will have the right, by written notice given within the next 36-hour period to the parties to this Agreement, to terminate this Agreement without liability on the part of the non-defaulting Underwriters or of the Company or of the Selling Shareholders

except to the extent provided in Sections 5 and 8 hereof. In the event of a default by any Underwriter or Underwriters, as set forth in this Section 9, the Closing Date or Option Closing Date, as the case may be, may be postponed for such period, not exceeding seven days, as you, as Representatives, may determine in order that the required changes in the Registration Statement, the General Disclosure Package or in the Prospectus or in any other documents or arrangements may be effected. The term “Underwriter” includes any person substituted for a defaulting Underwriter. Any action taken under this Section 9 shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

10. Notices.

All communications hereunder shall be in writing and, except as otherwise provided herein, will be mailed, delivered, telecopied and confirmed as follows: if to the Underwriters, to Deutsche Bank Securities Inc., at 60 Wall Street, 4th Floor, New York, New York 10005, United States, Attention: Samir Abu-Khadra, fax number +1-212-797-9344, with a copy to Deutsche Bank Securities Inc., at 60 Wall Street, 4th Floor, New York, New York 10005, United States, Attention: Equity Capital Markets Syndicate, to UBS AG, at 52/F, International Finance Center, 8 Finance Street, Central, Hong Kong, Attention: General Counsel, and to Citigroup Global Markets Inc., at 388 Greenwich Street, New York, New York 10013, United States, Attention: General Counsel, fax number +1-212-816-7912; if to the Company, to HiSoft Technology International Limited, 6/F Haya Plaza, 1 Shangdi East Road, Haidian District, Beijing 100085, People’s Republic of China, Attention: Chief Financial Officer, fax number +86-411-8479-1350 and +86-10-5987-5599; and if to a Selling Shareholder, to the address and facsimile number of such Selling Shareholder provided in Schedule II.

11. Termination.

This Agreement may be terminated by you by notice to the Company and the Selling Shareholders:

(a) at any time prior to the Closing Date or any Option Closing Date (if different from the Closing Date and then only as to Option ADSs) if any of the following has occurred: (i) since the respective dates as of which information is given in the Registration Statement, the General Disclosure Package and the Prospectus, any material adverse change or any development involving a prospective material adverse change in or affecting the earnings, business, management, properties, assets, rights, operations, condition (financial or otherwise) or prospects of the Company and the Subsidiaries taken as a whole, whether or not arising in the ordinary course of business, (ii) any outbreak or escalation of hostilities or declaration of war or national emergency or other national or international calamity or crisis (including, without limitation, an act of terrorism) or change in economic or political conditions if the effect of such outbreak, escalation, declaration, emergency, calamity, crisis or change on the financial markets of the United States, the PRC or the Cayman Islands would, in your judgment, make it impracticable or inadvisable to market the Offered ADSs, or (iii) suspension of trading in securities generally on the New York Stock Exchange, the NYSE Amex Equities, the Nasdaq Global Select Market, the Nasdaq Global Market or the Shanghai Stock Exchange or limitation on prices (other than limitations on hours or numbers of days of trading) for securities on any such Exchange, (iv) the enactment, publication, decree or other promulgation of any statute, regulation, rule or order of any court or other governmental authority which in your reasonable opinion materially and adversely affects or may materially and adversely affect

the business or operations of the Company, (v) the declaration of a banking moratorium by the United States, New York State, PRC or Cayman Islands authorities, (vi) the suspension of trading of the Company’s ADSs by the Nasdaq Global Market, the Commission, or any other governmental authority or, (vii) the taking of any action by any governmental body or agency in respect of its monetary or fiscal affairs which in your reasonable opinion has a material adverse effect on the securities markets in the United States, the PRC or the Cayman Islands; or

(b) as provided in Sections 6 and 9 of this Agreement.

12. Successors.

This Agreement has been and is made solely for the benefit of the Underwriters, the Company, the Selling Shareholders and their respective successors, executors, administrators, heirs and assigns, and the officers, directors and controlling persons referred to herein, and no other person will have any right or obligation hereunder. No purchaser of any of the Offered ADSs from any Underwriter shall be deemed a successor or assign merely because of such purchase.

13. Information Provided by Underwriters and Selling Shareholders.

The Company, the Selling Shareholders and the Underwriters acknowledge and agree that the only information furnished or to be furnished by any Underwriter to the Company for inclusion in the Registration Statement, any Preliminary Prospectus, any Issuer Free Writing Prospectus or the Prospectus consists of the information set forth in the second, third, fifth, fourteenth to twentieth, and twenty-third paragraphs under the caption “Underwriting” in the Prospectus.

The Company, the Selling Shareholders and the Underwriters acknowledge and agree that the only information pertaining to any Selling Shareholder furnished or to be furnished by such Selling Shareholder to the Company for inclusion in the Registration Statement, the General Disclosure Package or the Prospectus, or any amendment or supplement thereto, including for purposes of Section 1(b)(v) and 8(b) of this Agreement, is set forth opposite such Selling Shareholder’s name in the table (including information contained in the relevant footnotes therein) under the heading “Principal and Selling Shareholders” therein.

14. Applicable Law

This Agreement shall be governed by, and construed in accordance with, the law of the State of New York, including, without limitation, Section 5-1401 of the New York General Obligations Law.

The Company and the Selling Shareholders hereby submit to the non-exclusive jurisdiction of the Federal and state courts in the Borough of Manhattan in The City of New York in any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby. The Company and the Selling Shareholders irrevocably and unconditionally waive any objection to the laying of venue of any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby in Federal and state courts in the Borough of Manhattan in The City of New York and irrevocably and unconditionally waive and agree not to plead or claim in any such court that any such suit or

proceeding in any such court has been brought in an inconvenient forum. The Company and the Selling Shareholders irrevocably appoint Law Debenture Corporate Services Inc., 400 Madison Avenue, 4th Floor, New York, New York 10017, United States, as their respective authorized agent in the Borough of Manhattan in The City of New York upon which process may be served in any such suit or proceeding, and agree that service of process upon such agent, and written notice of said service to the Company or each Selling Shareholder by the person serving the same to the address provided in Section 10, shall be deemed in every respect effective service of process upon the Company or each Selling Shareholder, as the case may be, in any such suit or proceeding. The Company and the Selling Shareholders further agree to take any and all action as may be necessary to maintain such designation and appointment of such agent in full force and effect for a period of seven years from the date of this Agreement. All references in this paragraph to “Selling Shareholders” shall be deemed to exclude International Finance Corporation.

15. Miscellaneous.

The obligations of the Company and the Selling Shareholders pursuant to this Agreement in respect of any sum due to any Underwriter shall, notwithstanding any judgment in a currency other than United States dollars, not be discharged until the first business day, following receipt by such Underwriter of any sum adjudged to be so due in such other currency, on which (and only to the extent that) such Underwriter may in accordance with normal banking procedures purchase United States dollars with such other currency; if the United States dollars so purchased are less than the sum originally due to such Underwriter hereunder, the Company and each Selling Shareholder, severally and not jointly, agree, as a separate obligation and notwithstanding any such judgment, to indemnify such Underwriter against such loss. If the United States dollars so purchased are greater than the sum originally due to such Underwriter hereunder, such Underwriter agrees to pay to the Company or the Selling Shareholders, as the case may be, an amount equal to the excess of the United States dollars so purchased over the sum originally due to such Underwriter hereunder.

The reimbursement, indemnification and contribution agreements contained in this Agreement and the representations, warranties and covenants in this Agreement shall remain in full force and effect regardless of (a) any investigation made by or on behalf of any Underwriter, its directors or officers or controlling person thereof, or by or on behalf of the Company, or any of the Selling Shareholders or any of their respective officers or directors or controlling persons, as the case may be, and (b) acceptance of any Shares and payment therefor hereunder, and the reimbursement, indemnification and contribution agreements contained in this Agreement shall remain in full force and effect regardless of any termination of this Agreement; provided, however that if the termination of this Agreement is pursuant to Section 9, then only the reimbursement agreements contained in this Agreement shall remain in full force and effect. A successor to any Underwriter, its directors or officers or any person controlling any Underwriter, or to the Company, its directors or officers, or any person controlling the Company, shall be entitled to the benefits of the indemnity, contribution and reimbursement agreements contained in this Agreement.

The Company and the Selling Shareholders acknowledge and agree that each Underwriter in providing investment banking services to the Company and the Selling Shareholders in connection with the offering of the Offered ADSs, including in acting pursuant to the terms of this Agreement, has acted and is acting as an independent contractor and not as a fiduciary and the Company and the Selling Shareholders do not intend such Underwriter to act

in any capacity other than as an independent contractor, including as a fiduciary or in any other position of higher trust.

All payments made by the Company and the Selling Shareholders under this Agreement, if any and as the case may be, will be made without withholding or deduction for or on account of any present or future taxes, duties, assessments or governmental charges of whatever nature imposed or levied by or on behalf of the Cayman Islands or any political subdivision or any taxing authority thereof or therein unless the Company or a Selling Shareholder is or becomes required by law to withhold or deduct such taxes, duties, assessments or other governmental charges. In such event, the Company and or the applicable Selling Shareholder, severally and not jointly and in respects of amounts owed exclusively by such Selling Shareholder, as the case may be, will pay such additional amounts as will result, after such withholding or deduction, in the receipt by each Underwriter and each person controlling any Underwriter, as the case may be, of the amounts that would otherwise have been receivable in respect thereof, except to the extent such taxes, duties, assessments or other governmental charges are imposed or levied by reason of such Underwriter’s or controlling person’s being connected with the Cayman Islands other than by reason of its being an Underwriter or a person controlling any Underwriter under this Agreement.

Any rights of JAFCO Asia Technology Fund II (“JAFCO”) under this Agreement may, without prejudice to the rights of JAFCO to exercise any such rights, be exercised by JAFCO Investment (Asia Pacific) Ltd. (“JIAP”) or any other fund manager of JAFCO or their nominees (“JAFCO Manager”), unless JAFCO has (i) given notice to the other parties that any such rights cannot be exercised by JIAP or a JAFCO Manager; and (ii) not given notice to the other parties that such notice which is given under this Section 15 has been revoked.

This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

The Underwriters, on the one hand, and the Company and the Selling Shareholders, on the other hand, waive any right to trial by jury in any action, claim, suit or proceeding with respect to your engagement as underwriter or your role in connection herewith.

If the foregoing letter is in accordance with your understanding of our agreement, please sign and return to us the enclosed duplicates hereof, whereupon it will become a binding agreement among the Company, the Selling Shareholders and the several Underwriters in accordance with its terms.

The foregoing Underwriting Agreement is hereby confirmed and accepted as of the date first above written.

As representatives of the several Underwriters

Ladies and Gentlemen:

The undersigned understands that Deutsche Bank Securities Inc. (“Deutsche Bank”), UBS AG (“UBS”) and Citigroup Global Markets Inc., as representatives (the “Representatives”) of the several underwriters (the “Underwriters”) listed in Schedule I to the Underwriting Agreement (as defined below), propose to enter into an underwriting agreement (the “Underwriting Agreement”) on behalf of the several Underwriters with HiSoft Technology International Limited (the “Company”) and the several selling shareholders listed in Schedule II to the Underwriting Agreement (the “Selling Shareholders”), providing for the public offering (the “Public Offering”) by the Underwriters, including the Representatives, of common shares, par value $0.0001 per share (each a “Common Share”), of the Company represented by American depositary shares (“ADSs”).

To induce the Underwriters that may participate in the Public Offering to continue their efforts in connection with the Public Offering, subject to the condition precedent that all directors, officers and holders of most of the Company’s Common Shares are bound by restrictions substantially identical to those listed below, the undersigned agrees that, without the prior written consent of the Representatives, the undersigned will not, directly or indirectly, offer, sell, pledge, contract to sell (including any short sale), grant any option to purchase or otherwise dispose of any Common Shares or ADSs (including, without limitation, Common Shares or ADSs of the Company which may be deemed to be

C-1-1

beneficially owned by the undersigned on the date hereof in accordance with the rules and regulations of the Securities and Exchange Commission, Common Shares or ADSs which may be issued upon exercise of a stock option or warrant and any other security convertible into or exchangeable for Common Share or ADSs) or enter into any Hedging Transaction (as defined below) relating to Common Share or ADSs (each of the foregoing referred to as a “Disposition”) during the period specified in the following paragraph (the “Lock-Up Period”). The foregoing restriction is expressly intended to preclude the undersigned from engaging in any Hedging Transaction or other transaction which is designed to or reasonably expected to lead to or result in a Disposition during the Lock-Up Period even if the securities would be disposed of by someone other than the undersigned; provided, however, that nothing in this paragraph shall preclude the undersigned from engaging in any transaction in the securities of another company in the same sector or in a similar sector as that of the Company. “Hedging Transaction” means any short sale (whether or not against the box) or any purchase, sale or grant of any right (including, without limitation, any put or call option) with respect to any security (other than a broad-based market basket or index security) that includes, relates to or derives any significant part of its value from the Common Shares or ADSs.

The initial Lock-Up Period will commence on the date of the Underwriting Agreement and continue until, and include, the date that is 90 days after the date of the final prospectus relating to the Public Offering (the “Initial Lock-Up Period”); provided, however, that if (1) during the last 17 days of the Initial Lock-Up Period, (A) the Company releases earnings results or (B) material news or a material event relating to the Company occurs, or (2) prior to the expiration of the Initial Lock-Up Period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the Initial Lock-Up Period, then in each case the Lock-Up Period will be extended until the expiration of the 18-day period beginning on the date of the release of the earnings results or the occurrence of material news or a material event relating to the Company, as the case may be (the “Lock-Up Extension”), unless the Representatives waive, in writing, such Lock-up Extension; provided, however, that if NASD Rule 2711 or such later rule adopted by Financial Industry Regulatory Authority, Inc. related to extension of lock-up agreements in connection with the issuance of research reports (collectively, the “SRO Rules”) applies to the Representatives with respect to the Public Offering and there are any amendments or revisions to the SRO Rules reducing or removing the number of days before and after the waiver, termination or expiration of the lock-up during which no research can be published (the “Blackout Days”), the Lock-Up Extension shall be reduced to a number of days equal to: (a) if the number of Blackout Days required by the SRO Rules, as so amended or revised, is greater than zero, such number of Blackout Days plus three, or (b) if the number of Blackout Days required by the SRO Rules, as so amended or revised, is zero, zero.

Notwithstanding the foregoing, the undersigned may transfer (a) Common Shares or ADSs acquired in open market transactions by the undersigned after the completion of the Public Offering, (b) Common Shares or ADSs to the Underwriters pursuant to the Underwriting Agreement, (c) Common Shares or ADSs with the prior written consent of the Representatives, or (d) any or all of the Common Shares or ADSs or other Company securities if the transfer is by (i) gift, will or intestacy, (ii) Disposition to partners (limited or general), members or shareholders of the undersigned, any direct or indirect affiliate or subsidiary of the undersigned, or any investment fund or other entity controlled or managed by the undersigned, or (iii) Disposition to a member of the immediate family of the undersigned or any trust for the direct or indirect benefit of the undersigned or a member of

Any such securities so released pursuant to this clause must be sold within five (5) business days of the Triggering Release (or such longer period granted to the Triggering Release Party by the Representatives) in a coordinated manner as proposed by the Representatives. If such securities are not sold within such five business-day or longer period granted by the Representatives, then the lock-up provisions contained herein shall continue to apply to such securities. The Representatives shall notify the undersigned in writing of any Triggering Release within three (3) business days thereafter.

The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of such Common Shares or ADSs of, the undersigned except in compliance with the foregoing restrictions.

The undersigned hereby agrees that, to the extent that the terms of this Lock-Up Agreement conflict with or are in any way inconsistent with any registration rights agreement to which the undersigned and the Company may be a party, this Lock-Up Agreement supersedes such registration rights agreement.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Lock-Up Agreement. The undersigned understands that this Lock-Up Agreement shall be binding upon the undersigned’s heirs, legal representatives, successors and assigns.

Notwithstanding anything herein to the contrary, if (i) the closing of the Public Offering has not occurred on or prior to the 60th day following the execution of the Underwriting Agreement by all parties thereto, or (ii) the Underwriting Agreement has been terminated for any reason, then, this Lock-Up Agreement shall terminate and be of no further force or effect.
