To the extent requested by Purchasers, the Sellers shall commence appropriate proceedings before the Bankruptcy Court and otherwise take all reasonably necessary actions in order to determine Cure Costs with respect to any Assumed Contract or Assumed Lease entered into prior to the Petition Date. Notwithstanding the foregoing, prior to the Closing, Wanxiang may identify any Assumed Contract or Assumed Lease as one that Wanxiang no longer desires to have assigned to it or a Wanxiang Designee in accordance with Section 2.9.

(i) At the Closing, the Sellers shall assume and assign to Wanxiang and/or, as applicable, one or more Wanxiang Designees the Assumed Contracts and Assumed Leases, in each case pursuant to Section 365 of the Bankruptcy Code and the Sale Order, subject to provision by Purchasers of adequate assurance as may be required under Section 365 of the Bankruptcy Code and payment by Purchasers of the Cure Costs in respect of the Assumed Leases and Assumed Contracts. The Cure Costs in respect of all of the Assumed Leases and Assumed Contracts shall be paid (or otherwise satisfied) by Purchasers.

(b) Notwithstanding anything in this Agreement to the contrary, to the extent that the sale, transfer, assignment, conveyance or delivery or attempted sale, transfer, assignment, conveyance or delivery to Wanxiang and/or, as applicable, one or more Wanxiang Designees of any asset that would be a Purchased Asset or an Assumed Liability or any claim or right or any benefit arising thereunder or resulting therefrom is prohibited by any applicable Law or would require any Consent from any Governmental Authority or any other third party (after giving effect to the Sale Order and the Bankruptcy Code) and such Consents shall not have been obtained prior to the Closing, the Closing shall proceed without the sale, transfer, assignment, conveyance or delivery of such asset (and without reduction in the Purchase Price) unless there is a failure of one or more of the conditions set forth in Article VI, in which event the Closing shall proceed only if each failed condition is waived by the Party entitled to the benefit thereof. In the event that any failed condition is waived and the Closing proceeds without the transfer or assignment of any such asset, then following the Closing, the Purchasers and the Sellers shall use their respective reasonable best efforts, and cooperate with each other, to obtain promptly such Consent. Pending such Consent, the Parties shall reasonably cooperate with each other to provide Purchasers and the Wanxiang Designees with all of the benefits of use of such asset free of any cost or expense. Once Consent for the sale, transfer, assignment, conveyance or delivery of any such asset not sold, transferred, assigned, conveyed or delivered at the Closing is obtained, the Sellers shall promptly transfer, assign, convey and deliver such asset to Wanxiang and/or, as applicable, one or more Wanxiang Designees at no additional cost or expense. To the extent that any such asset cannot be transferred or the full benefits or use of any such asset cannot be provided to Wanxiang and/or, as applicable, one or more Wanxiang Designees following the Closing but in any event no later than the date that is 90 days after the Closing pursuant to this Section 2.8(b), then, the Purchaser and the Sellers shall enter into such arrangements (including subleasing, sublicensing or subcontracting) to provide to the Parties hereto the economic (taking into account Tax costs and benefits) and operational equivalent of obtaining such Consent. The Sellers shall hold in trust for, and pay to Wanxiang and/or, as applicable, one or more Wanxiang Designees, promptly upon receipt thereof, all income, proceeds and other monies received by the Sellers derived from its use of any asset that would be a Purchased Asset in connection with the arrangements under this Section 2.8(b).

(c) If, following the Closing, any Seller receives or becomes aware that it holds any asset, property or right which constitutes a Purchased Asset, then Sellers shall transfer such asset, property or right to Wanxiang and/or, as applicable, one or more Wanxiang Designees as promptly as practicable for no additional consideration.

(d) If, following the Closing, Wanxiang receives or becomes aware that it holds any asset, property or right which constitutes an Excluded Asset, then Wanxiang shall transfer such asset, property or right to the Sellers as promptly as practicable for no additional consideration.

(e) If, following the Closing, any Seller or Wanxiang becomes aware that any of the Excluded IP was necessary for the operation of the Sellers’ Business as operated as of the Closing Date, then Sellers shall immediately take all such actions as may be required to obtain or grant a license to Wanxiang for such Excluded IP, subject to any rights of Third Parties in such Excluded IP, including without limitation obtaining necessary Consents therefore as promptly as practicable for no additional consideration; provided, however, that any Excluded IP that constitutes ITAR-Controlled Assets will be expressly excluded from any such license to Wanxiang.

Section 2.9 Additional and Eliminated Assumed Contracts. Notwithstanding anything in this Agreement to the contrary, Wanxiang may, in its sole and absolute discretion, amend or revise Schedules 1.2(a) and 1.2(b) of the Purchaser Schedule setting forth the Assumed Contracts and the Assumed Leases, respectively, in order to add or eliminate any Contract or Lease to such Purchaser Schedule up to one (1) Business Day prior to the Closing Date (the “Designation Deadline”) and, for any particular Assumed Contract or Assumed Lease that will be assumed in whole or in part by a Wanxiang Designee, to identify such Wanxiang Designee; provided, however, that (a) subject to the last sentence of this Section 2.9, the Sellers may terminate or reject any Contract set forth on Schedule 2.9 to the Disclosure Letter at any time whether prior to or after the Designation Deadline; and (b) Wanxiang may not amend or revise Schedules 1.2(a) and 1.2(b) of the Purchaser Schedule after the date hereof to add any Contract or Lease to such Purchaser Schedule if Sellers have provided written notice to Wanxiang no later than the date hereof that Sellers have reached an agreement in principle with a Third Party to assign, transfer or sell such Contract or Lease to such Third Party (it being understood that no Contract or Lease that has already been designated as a Purchased Asset may be the subject of any such agreement in principle). Automatically upon the addition of any Contract to Schedule 1.2(a) of the Purchaser Schedule or Lease to Schedule 1.2(b) of the Purchaser Schedule, it shall be an Assumed Contract or Assumed Lease, as applicable, for all purposes of this Agreement. Automatically upon the deletion of any Contract from Schedule 1.2(a) of the Purchaser Schedule or deletion of any Lease from Schedule 1.2(b) of the Purchaser Schedule (any such deleted Contract or Lease, an “Eliminated Agreement”), it shall be an Excluded Agreement for all purposes of this Agreement, and no Liabilities arising thereunder shall be assumed or borne by the Purchasers. If Wanxiang indicates in writing to Sellers after the Closing Date that it wishes to acquire a Contract or Lease of any Seller that was not an Assumed Contract or Assumed Lease on the Closing Date and that Sellers have not reached any agreement in principle with a Third Party to assign, transfer or sell such Contract or Lease to such Third Party, then the Sellers will, subject to reaching an agreement with Wanxiang regarding consideration therefor, if any, use their commercially reasonable efforts to assign such Contract or Lease to Wanxiang; provided,

however, that nothing herein shall be deemed or construed to obligate the Sellers to retain, or refrain from rejecting or terminating any Contract after the Designation Deadline that does not constitute an Assumed Contract or Assumed Lease. With respect to each Assumed Contract and Assumed Lease, Wanxiang and, as applicable, the Wanxiang Designees shall provide adequate assurance of the future performance of such Assumed Contract or Assumed Lease by Wanxiang and, as applicable, such Wanxiang Designees. Notwithstanding anything to the contrary herein, Sellers shall not be obligated to assume and assign any Assumed Contract or Assumed Lease with respect to which Purchasers fail to satisfy the Bankruptcy Court as to adequate assurance of future performance (collectively, if any, the “Non-Assured Contracts”) and Purchasers’ obligation to close the Transactions shall not be conditioned upon the transfer and assignment to Purchasers of any such Non-Assured Contracts. Notwithstanding anything to the contrary herein, (i) Sellers shall not reject, repudiate or terminate any license or Contract in respect of Intellectual Property Rights and (ii) other than licenses or Contracts in respect of Intellectual Property Rights (treatment of which is governed by clause (i) of this sentence), Sellers shall not reject, repudiate or terminate any Contract or Lease that may potentially constitute or implicate any Purchased Asset unless (A) Sellers shall provide Purchaser at least five (5) Business Days’ prior written notice of such potential rejection, repudiation or termination (which notice shall specify the Contracts or Leases to be rejected and include a true and complete copy of such Contracts or Leases) and (ii) Purchaser has not objected to such rejection, repudiation or termination.

(a) On November 8, 2012 Purchasers deposited into escrow an ▇▇▇▇▇▇▇ money deposit (the “Purchase Price Deposit”) in the amount of $13,300,100 as security for the performance of the Purchasers’ obligations under this Agreement. The Purchase Price Deposit, together with any interest thereon, shall be applied against the Purchase Price at Closing and disbursed to the Sellers in accordance with the procedures set forth in the Deposit Escrow Agreement.

The CFIUS Deposit, together with any interest thereon, shall be applied against the Purchase Price at Closing and disbursed to the Sellers in accordance with the procedures set forth in the CFIUS Escrow Agreement. Except as set forth in Section 2.10(d), if this Agreement shall be terminated pursuant to Section 8.1, the CFIUS Deposit, together with any interest earned thereon, shall be delivered to the Purchasers in accordance with the procedures set forth in the CFIUS Escrow Agreement.

(d) If this Agreement is terminated by Sellers pursuant to Section 8.1(j), the CFIUS Deposit, shall be delivered to the Sellers in accordance with the procedures set forth in the CFIUS Escrow Agreement.

Section 2.11 Withholding. Notwithstanding anything in this Agreement to the contrary, the Purchasers shall be entitled to deduct and withhold from any amounts otherwise payable pursuant to this Agreement any amount as may be required to be deducted and withheld with respect to the making of such payment under applicable U.S. federal, state or local or foreign laws. To the extent that amounts are so deducted and withheld by a Purchaser, such deducted and withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Sellers or other Person in respect of which such deduction and withholding was made by the Purchaser.

None of the Excluded IP has been or is used in the business of the A123 Entities as conducted prior to the date hereof other than the USG Business. There are no Intellectual Property Rights that do not constitute Purchased IP but are used in the business of the A123 Entities, other than the Excluded IP which is used solely in the USG Business.

(i) Schedule 4.1(o)(i) sets forth a true and complete list of all U.S. and foreign Intellectual Property Rights owned (whether in whole or in part) by or licensed to or used by Sellers that are issued, pending or registered, including all registered Purchased IP (marked as such), as well as any Excluded IP, in each case indicating which A123 Entities own or have rights to use such Intellectual Property Rights and with

respect to which businesses of A123 Entities such Intellectual Property Rights are used or are relevant.

(ii) Except as set forth on Schedule 4.1(o)(ii), Sellers have all right, title and interest in and to the Intellectual Property Rights designated as owned by Sellers on Schedule 4.1(o)(i), free and clear of all Encumbrances other than Permitted Encumbrances. All current and former employees of the A123 Entities have assigned to the A123 Entities all Purchased IP that such employees have created while in the scope of their employment, including copyrights in works made for hire and patents.

(iii) Schedule 4.1(o)(iii) sets forth each Contract with respect to Purchased IP pursuant to which the A123 Entities have granted or are obligated to grant any Person the right to license, reproduce, distribute, market, use or exploit such Intellectual Property Rights or otherwise granted covenants not to ▇▇▇, releases or immunities regarding such Intellectual Property Rights.

(iv) Except as set forth on Schedule 4.1(o)(iv), all registered Intellectual Property Rights of Seller are in full force and effect, and have not been abandoned or passed into the public domain, and all necessary registration, maintenance and renewal documentation and fees in connection with such Intellectual Property Rights have been timely filed with the appropriate authorities and paid. Sellers have in place commercially reasonable policies and procedures, consistent with industry standards, to maintain the secrecy of all trade secrets included in their Intellectual Property Rights. The A123 Entities are not using any registered Intellectual Property Rights in a manner that would reasonably be expected to result in the cancellation or unenforceability of such Intellectual Property Rights.

(v) Except as set forth on Schedule 4.1(o)(v), (A) there are no Actions before any Governmental Authority with respect to the Intellectual Property Rights of any A123 Entity or, to the Knowledge of Sellers, any Actions before any Governmental Authority with respect to Intellectual Property Rights which are otherwise used in the business of the A123 Entities, (B) there is no Action pending, or to the Knowledge of the Sellers, threatened that challenges the validity of ownership or use of any Purchased Assets, and (C) to the Knowledge of Sellers, there exists no state of facts and circumstances that would result in any such challenge that is material to the business of the Sellers being successful or which would be reasonably likely to result in a material liability or otherwise have a Material Adverse Effect.

(vi) To the Knowledge of the Sellers, no third party’s operations or products infringe on the Purchased IP in any material respect. To the Knowledge of the Sellers, the operation of the business of the A123 Entities does not infringe in any material respect on the Intellectual Property Rights of any other Person. No A123 Entity has received, or been threatened with, during the three-year period preceding the date of this Agreement, any written (or, to the Knowledge of Sellers, non-written) claim of infringement with respect to any Purchased IP.

(p) Upon the consummation of the Closing, Buyer shall succeed to all of Sellers’ rights and interest in or under the Purchased IP, and all of Sellers’ rights under the Intellectual Property Rights that constitute the Purchased IP shall be exercisable by Purchasers to the same extent as by Sellers prior to the Closing. The execution, delivery and performance by Sellers of this Agreement and the Ancillary Agreements, and the consummation of the transactions contemplated hereby or thereby, will not give rise to any right of any third party to terminate or re-price or otherwise modify any of its rights or obligations under any agreement under which any right or license is granted under any of the Purchased IP.

(q) Schedule 4.1(q) of the Disclosure Letter sets forth a complete list of all material insurance policies with respect to which an A123 Entity is a party, a named insured or otherwise the beneficiary of coverage with respect to any of the Purchased Assets or the Assumed Liabilities. The Purchased Assets have been insured against risks normally covered by insurance policies by companies carrying on business of a similar nature as each of the A123 Entities. There is no material claim with respect to any Purchased Asset by an A123 Entity pending under any such policies which has been denied or disputed by the insurer. To the Knowledge of the Sellers, all such insurance policies are in full force and effect, all premiums due and payable thereon have been paid, all material terms and conditions of such policies have been complied with, and no written notice of cancellation or termination has been received by the A123 Entities with respect to any such policy which is not replaceable by the A123 Entities or on substantially similar terms prior to the date of such cancellation.

(r) All material Tax Returns required to be filed by each Seller or any of its Affiliates (with respect to the Sellers’ Business, the Purchased Assets or the Assumed Liabilities) or by or on behalf of each Foreign Subsidiary have been timely filed (taking into account extensions validly obtained), (ii) all such Tax Returns were true, correct and complete in all material respects, and (iii) all Taxes shown as due on such Tax Returns and any other material Taxes of any Seller or its Affiliates (with respect to the Sellers’ Business, the Purchased Assets or the Assumed Liabilities) or the Foreign Subsidiaries have been timely paid other than Taxes being contested in good faith by appropriate proceedings and for which adequate reserves have been established in accordance with GAAP in the Financial Statements or, for periods beginning after June 30, 2012, the Books and Records of A123 Systems. During the last five years, no claim has been made in writing by any taxing authority in a jurisdiction where any Seller or any of its Affiliate or the Foreign Subsidiaries does not file Tax Returns that such Seller or its Affiliate (with respect to the Sellers’ Business, the Purchased Assets or the Assumed Liabilities) or the Foreign Subsidiaries is or may be subject to taxation by that jurisdiction. Each Seller and its Affiliates (to the extent relating to the Sellers’ Business, the Purchased Assets or the Assumed Liabilities) and the Foreign Subsidiaries have withheld and paid to the relevant taxing authority all material Taxes required to have been withheld and paid in connection with amounts paid or owing to any employee, independent contractor, creditor, stockholder or other third party. No audit, administrative proceeding or judicial proceeding that involves a material amount of Tax of any Seller or its Affiliates (with respect to the Sellers’ Business, the Purchased Assets or the Assumed Liabilities) or the Foreign Subsidiaries is pending or threatened in writing. There are no Encumbrances for Taxes on the Purchased Assets or any property of the Foreign Subsidiaries other than statutory Encumbrances for Taxes not yet due and payable. None of the Purchased Assets or property of the Foreign Subsidiaries is “tax exempt use property” within the meaning of Section 168(h) of the Code or subject to any lease made pursuant to Section 168(f)(8) of the

Internal Revenue Code of 1954. Other than the equity interest in the Foreign Subsidiaries and the Joint Venture, the Purchased Assets do not include, directly or indirectly, any equity interests in any corporation, partnership, limited liability company or other entity nor is any Purchased Asset required to be treated as such for U.S. federal income tax purposes. Each of the Foreign Subsidiaries and the Joint Venture is characterized as a foreign corporation for U.S. federal income tax purposes. Neither the Foreign Subsidiaries nor the Joint Venture (i) has elected to be treated as a domestic corporation under Section 897(i) of the Code, (ii) is treated as a domestic corporation under Section 7874(b) of the Code; (iii) is a “passive foreign investment company” within the meaning of Section 1297 of the Code or (iv) except for the Foreign Subsidiaries, is a “controlled foreign corporation” within the meaning of Section 957 of the Code. The Foreign Subsidiaries will not be required to include any material item of income in, or exclude any material item of deduction from, taxable income for any Post-Closing Tax Period as a result of any (i) adjustment required by reason of a change in method of accounting under Section 481(c) of the Code (or any corresponding or similar provision of state, local or foreign law) on or prior to the Closing Date, (ii) “closing agreement” as described in Section 7121 of the Code (or any corresponding or similar provision of state, local or foreign law) entered into on or prior to the Closing Date, (iii) installment sale or intercompany transaction made on or prior to the Closing Date, (iv) any prepaid amounts received on or prior to the Closing Date or (v) any election under Section 108(i) of the Code (or any corresponding or similar provision of state, local or foreign law) made on or prior to the Closing Date. No waiver or extension of any federal, state, local or foreign statutes of limitation has been granted with respect to the assessment of any material Taxes of the Sellers or its Affiliates (to the extent relating to the Sellers’ Business, the Purchased Assets or the Assumed Liabilities) or the Foreign Subsidiaries, which waiver or extension has not since expired. Each of the Foreign Subsidiaries (i) has not participated in a “listed transaction” within the meaning of Treasury Regulation Section 1.6011-4(b), (ii) has not granted to any Person a power of attorney that is currently in force with respect to any Tax matter, (iii) has never been a member of an affiliated, consolidated, combined or unitary group, and (iv) has not constituted either a “distributing corporation” or a “controlled corporation” (within the meaning of Section 355(a)(1)(A) of the Code) in a distribution of stock intended to qualify for tax-free treatment under Section 355 of the Code within the past three years. None of the Sellers and their Affiliates (with respect to the Sellers’ Business, the Purchased Assets, or the Assumed Liabilities) or the Foreign Subsidiaries has requested or received a ruling from the Internal Revenue Service or other material ruling in respect of Taxes, in each case, which would bind the Purchases or their Affiliates (including the Foreign Subsidiaries) after the Closing. There are no Tax allocation, Tax sharing or Tax indemnification agreements or other similar arrangements pursuant to which the Foreign Subsidiaries would be liable after the Closing for Taxes of any other Person.

(s) Subject to the entry of the Sale Order and any order approving the assumption and assignment of the Assumed Contracts and Assumed Leases, the Sellers have complied with all requirements of the Bankruptcy Code and Federal Rules of Bankruptcy Procedure in connection with obtaining approval of the sale of the Purchased Assets (including the assumption and assignment to Wanxiang and/or, as applicable, one or more Wanxiang Designees of any Assumed Contracts and the Assumed Leases) to Wanxiang and/or, as applicable, one or more Wanxiang Designees pursuant to this Agreement.

(t) During the period beginning on September 30, 2009 to the date of this Agreement, there has not been any material damage to the Purchased Assets that are tangible assets and used in the business of the A123 Entities in respect of which the Sellers are entitled to insurance proceeds, condemnation awards or other compensation. Inventory that is finished goods or samples is in good and marketable condition in all material respects and is reasonably saleable in the ordinary course of business.

(u) The Financial Statements present fairly in all material respects, the consolidated financial condition of A123 Systems as of the dates set forth therein, and the consolidated results of operations and cash flows for the periods covered thereby, in conformity with GAAP (subject, in the case of the Unaudited Financial Statements, to the absence of notes and normal year-end audit adjustments and to any other adjustments set forth therein). There is no outstanding guarantee, indemnity, suretyship or security (whether or not legally binding) given by or for the benefit of the Foreign Subsidiaries. Schedule 4.1(u) sets forth unaudited consolidation schedules in respect of each of the Unaudited Financial Statements described in clause (a) of the definition of Unaudited Financial Statements (the “Consolidation Schedules”). The Foreign Subsidiaries do not have any material liabilities or obligations of any nature (whether absolute or contingent, asserted or unasserted, known or unknown, primary or secondary, direct or indirect, and whether or not accrued), except (i) as disclosed, reflected or reserved against in the Consolidation Schedules related to the Foreign Subsidiaries, (ii) for liabilities and obligations incurred in the ordinary course of business consistent with past practice since June 30, 2012 and not in violation hereof.

(v) Set forth on Schedule 4.1(v) is a list of all suppliers of any A123 Entity or subcontractors of any products of or relating to the Sellers’ Business and indicates whether any such suppliers or subcontractors is the sole or primary supplier of any significant product, service or other tangible or intangible property or license rights to the Sellers.

(w) Since January 1, 2012, no Material Adverse Effect has occurred. From June 30, 2012 through the date of this Agreement, except as set forth on Schedule 4.1(w), Sellers have not taken any action that would have required the consent of Purchasers under Section 5.1 if taken after the date hereof.

(x) The Sellers have delivered or made available to the Purchasers a true, correct and complete copy of each writing constituting a part of each U.S. Benefit Plan and Foreign Benefit Plan maintained for the benefit of a Service Provider, including all plan documents, employment agreements, employee communications, summary plan descriptions, benefit schedules, trust agreements, and insurance contracts and other funding vehicles. Except as provided pursuant to the immediately preceding sentence, there are no amendments to any U.S. Benefit Plan or Foreign Benefit Plan maintained for the benefit of a Service Provider that have been adopted or approved nor have the Sellers undertaken to make any such amendments or to adopt or approve any new U.S. Benefit Plan or Foreign Benefit Plan. A123 Systems Hong Kong, Ltd. has no employees and has never had any employees.

(y) Except as prohibited by applicable Law, the Sellers have made available (or will make available within two (2) Business Days of the date hereof) to the Purchasers a list of all employees employed in the conduct of the business of the A123 Entities as of the date

specified therein, including the following information for each such employee: (i) name and location; (ii) part-time or full-time status; (iii) title, job description and responsibilities; (iv) employment commencement date; (v) annual base salary or hourly wage; (vi) available bonus or other contingent compensation; (vii) accrued and unused vacation days; (viii) accrued and unused sick days; (ix) if on leave, the status of such leave (including reason for leave and expected return date); (x) whether such employee is employed under an employment contract or on an at-will basis; and (xi) whether such employee has or had any responsibilities, involvement, or connection with respect to any of the Purchased Assets or Assumed Liabilities.

(z) Since January 1, 2009, with respect to the employees of the A123 Entities, there has not been, there is not presently pending or existing, and, to the Knowledge of the Sellers, there is not threatened any material charge, grievance proceeding or other claim against any A123 Entity (or any director, officer, manager or employee thereof) relating to the actual or alleged violation of any applicable Law pertaining to labor relations or employment matters, including any charge or complaint filed by an employee or union with the National Labor Relations Board, the Equal Employment Opportunity Commission or any comparable Governmental Authority. To the Knowledge of Sellers, no Seller has a material claim, whether asserted or unasserted, against any current or former employee of an A123 Entity. Sellers believe their relations with their employees are good. As of the date hereof, no officer of any A123 Entity has notified any Seller that such officer intends to leave or otherwise terminate such officer’s employment with Sellers. No employee of any A123 Entity, to the Knowledge of the Sellers, is, or is now expected to be, in violation of any material term of any employment contract, confidentiality, disclosure or proprietary information agreement, non-competition agreement, or any other contract or any restrictive covenant, and the continued employment of each such employee does not subject any A123 Entity to any liability with respect to any of the foregoing matters.

(aa) No A123 Entity has been, nor is any now, a party to any collective bargaining agreement, union recognition agreement or other labor contract or employs any member of a union. There is not pending or existing, and to the Knowledge of the Sellers, there is not threatened, any strike, slowdown, picketing, work stoppage or employee grievance process involving any A123 Entity. To the Knowledge of the Sellers, there is no organizational activity or other labor dispute against any A123 Entity, and no application or petition for an election of or for certification of a collective bargaining agent is pending. There is not in effect any lock-out, relating to a labor dispute, by any A123 Entity of any employee (or group thereof), and no such action is contemplated by any A123 Entity.

(bb) Each A123 Entity has in all material respects complied, and is in material compliance, with all laws and regulations in respect of wages and employment (including the Worker Adjustment and Retraining Notification Act (“WARN”) and all similar state, local and foreign laws). Without limiting the generality of the foregoing, each individual who renders services to any A123 Entity who is classified by such A123 Entity as having the status of an independent contractor or other non-employee status for any purpose (including for purposes of taxation and tax reporting and under U.S. Benefit Plans and Foreign Benefit Plans) is properly so characterized.

(cc) Each of Sellers and each of the Foreign Subsidiaries has in respect of each of its employees complied in all material respects with its obligations under applicable Law. Each Seller and each of the Foreign Subsidiaries has made all material payments due in respect of salaries, wages, commissions, bonuses, provident fund, pension, retirement benefits, gratuity, layoff, leave encashment, overtime pay, medical and workmen’s compensation and any other compensation element forming part of the compensation package with respect to the employees or any comparable payments relevant under any particular applicable Law. There does not now exist, nor do any circumstances exist that could result in, any Controlled Group Liability that would be a liability of the Foreign Subsidiaries or any of its ERISA Affiliates and that could result in liability to Wanxiang or any of its Affiliates (including, following the Closing, the Foreign Subsidiaries).

(dd) All Foreign Benefit Plans (i) have been maintained in all material respects in accordance with applicable Law, (ii) that are intended to qualify for special Tax treatment meet all material requirements for such treatment, and (iii) that are required to be funded and/or book reserved are funded and/or book-reserved, as appropriate, based upon reasonable actuarial assumptions and in accordance with applicable Law.

(ee) Neither the execution and delivery of this Agreement nor the consummation of the Transaction will (either alone or in conjunction with any other event) result in, cause the accelerated vesting, funding or delivery of, or increase the amount or value of, any payment or benefit to any Service Provider, or result in any limitation on the right of the Sellers to amend, merge, terminate or receive a reversion of assets from any U.S. Benefit Plan or Foreign Benefit Plan or related trust. Without limiting the generality of the foregoing, no amount paid or payable (whether in cash, in property, or in the form of benefits) by the Sellers in connection with the Transaction (either solely as a result thereof or as a result of the Transaction in conjunction with any other event) will be an “excess parachute payment” within the meaning of Section 280G of the Code.

(ff) Schedule 4.1(ff) sets forth all functions and responsibilities of each of the Excluded Personnel as of the date hereof, other than functions and responsibilities performed solely in connection with the USG Business.

Section 4.2 Representations and Warranties of the Purchasers.

(f) Each Purchaser will have, at the Closing, the resources and capabilities (financial or otherwise) to perform its obligations hereunder, including payment of the Purchase Price. Wanxiang has not incurred any obligation, commitment, restriction or liability of any kind that would materially impair Wanxiang’s ability to satisfy its payment and funding obligations under this Agreement.

Section 5.11 Certain Matters Relating to Specified Employees.

(a) No later than four (4) weeks after the date hereof, Wanxiang will notify Sellers of the identity of the employees of Sellers and their Affiliates to whom Wanxiang

(and/or, as applicable, one (1) or more Wanxiang Designees) intends to offer employment (each, a “Specified Employee,” and together, the “Specified Employees”), such offers to be made no later than five (5) days prior to the Closing Date and to be effective as of the Closing Date, provided that no such offer shall be made to any Excluded Personnel. Each such offer of employment shall be subject to such compensation and other terms and conditions of employment as Wanxiang shall determine in its sole and absolute discretion. Each such Specified Employee who accepts an offer of employment from Wanxiang or a Wanxiang Designee and is hired by Wanxiang or a Wanxiang Designee is referred to herein as a “Transferred Employee.”

(b) Notwithstanding Section 5.11(a), nothing herein expressed or implied shall confer upon any of the employees of any Seller or any Transferred Employees any right to employment or continued employment for any specified period, of any nature or kind whatsoever under or by reason of this Agreement.

(c) Neither Wanxiang, nor any Wanxiang Designee nor any Affiliate of Wanxiang shall have any Liability whatsoever for (i) any compensation or other obligations owing or purported to be owing to any Service Provider by any Seller, including any severance, separation pay, change of control payments or benefits, retention payments or any other payments or benefits arising in connection with the termination of such Service Provider’s employment by or services to any Seller, before, on or after the Closing Date, or (ii) any Action under WARN by any past or present Service Provider (whether or not a Transferred Employee) in connection with termination of employment with or services to any Seller and its Affiliates (or any other “employment loss” or similar action identified in WARN), including any plant closing or mass layoff. As soon as reasonably practicable following Wanxiang’s request, Sellers shall reasonably provide Wanxiang with such information as is reasonably necessary to determine whether any actions taken by Sellers or their applicable Affiliates prior to, on or after the Closing Date will, if aggregated with actions that may be taken by Wanxiang or its Affiliates after the Closing Date, require the provision of notice or payment in lieu of notice (whether under WARN or otherwise) to any individuals. To the extent requested by Wanxiang between the date hereof and the Closing, Seller will promptly deliver notices complying with WARN to Service Providers with respect to whom such a request is made.

(d) Effective upon the Closing Date, each of the Sellers hereby waives, for the benefit of Wanxiang and its Affiliates, any and all restrictions, if any, in any U.S. Benefit Plan, Foreign Benefit Plan or Contract relating to (i) non-competition with any A123 Entity, or (ii) maintenance of confidentiality of any information for the benefit of any A123 Entity, in each case, with or covering any Transferred Employee.

(e) To the extent that service is relevant for purposes of eligibility, vesting or benefit accrual (other than with respect to any defined benefit plan, program or arrangement) under any employee benefit or fringe benefit plan, program or arrangement established or maintained by Wanxiang or its Affiliates after the Closing in which Transferred Employees participate (a “Purchaser Benefit Plan”), such Purchaser Benefit Plan shall credit each Transferred Employee for service on or prior to the Closing Date with the A123 Entities and their Affiliates to the same extent credited for such purposes under the comparable U.S. Benefit Plan or Foreign Benefit Plan immediately prior to the Closing; provided that the foregoing shall

not apply (i) for purposes of any Purchaser Benefit Plan under which similarly situated employees of Wanxiang and its Affiliates do not receive credit for prior service, (ii) for purposes of any Purchaser Benefit Plan that is grandfathered or frozen, either with respect to level of benefits or participation, (iii) for purposes of level of severance payments or benefits under any Purchaser Benefit Plan, or (iv) to the extent that its application would result in a duplication of benefits with respect to the same period of service. Following the Closing, Wanxiang shall cause each Purchaser Benefit Plan which is an “employee welfare plan” (as defined in Section 3(1) of ERISA) in which Transferred Employees participate (i) to reduce each such eligible Transferred Employee’s (and his or her eligible dependents’) annual deductible limits under such plan for the plan year in which the Closing occurs to the extent deductible expenses were incurred and recognized for comparable purposes under the comparable U.S. Benefit Plan or Foreign Benefit Plan immediately prior to the Closing and (ii) to the extent waived under the comparable U.S. Benefit Plan or Foreign Benefit Plan in which Transferred Employees participate immediately prior to the Closing, to waive any pre-existing condition limitations or exclusions that do not apply to such Transferred Employees immediately prior to the Closing.

(f) Subject to applicable Laws, the Sellers shall cooperate with Wanxiang and shall permit Wanxiang and/or, as applicable, one or more Wanxiang Designees a reasonable period during normal business hours prior to the Closing Date, (i) to meet with Service Providers at such times as Wanxiang or a Wanxiang Designee shall reasonably request, (ii) to speak with such Service Providers’ managers and supervisors (in each case with appropriate authorizations and releases from such Service Providers) who are being considered for employment by Wanxiang or a Wanxiang Designee, (iii) to distribute to such Service Providers such forms and other documents relating to potential employment by or services to Wanxiang or a Wanxiang Designee after the Closing, and (iv) subject to any restrictions imposed under applicable Law, to permit Wanxiang, upon request, to review personnel files and other relevant employment information regarding such Service Providers.

(g) Following the Closing, the Sellers and Wanxiang shall cooperate reasonably with each other to provide an orderly administrative transition to Wanxiang and/or, as applicable, one or more Wanxiang Designees of the Transferred Employees, including the provision by the Sellers to Wanxiang of all necessary or appropriate documents, records, materials, accounting files and Tax information with respect to each Transferred Employee.

(h) Following the Closing, the Sellers shall retain all Liability to provide health care continuation coverage under Section 4980B of the Code and Section 601 of ERISA for all M&A Qualified Beneficiaries (as that term is defined in Treasury Regulations Section 54.4980B-9, Q&A-4) (who are not Transferred Employees or qualified beneficiaries of Transferred Employees first claiming COBRA benefits following a termination of employment with Wanxiang and its Affiliates) so that neither Wanxiang nor any of its Affiliates is required by applicable Law to provide COBRA continuation coverage to any of such M&A Qualified Beneficiaries.

(i) Nothing in this Section 5.11 shall (i) be treated or construed as an amendment of, or undertaking to amend, any benefit plan or (ii) be construed to prohibit Purchaser or any of its Affiliates from amending or terminating any benefit plan. The provisions of this Section 5.11 are solely for the benefit of the respective parties to this Agreement and

nothing in this Section 5.11, express or implied, shall confer upon any Service Provider, or legal representative or beneficiary thereof or other Person, any rights or remedies, including any right to employment or continued employment for any specified period, or compensation or benefits of any nature or kind whatsoever under this Agreement or a right in any employee or beneficiary of such employee or other Person under a U.S. Benefit Plan, Foreign Benefit Plan or Purchaser Benefit Plan that such Service Provider or beneficiary or other Person would not otherwise have under the terms of such plan.

Section 5.12 Non-Competition; Non-Solicitation.

(a) From the Closing Date until the fifth anniversary thereof, Seller and each of its Affiliates shall not directly or indirectly engage or participate in any business that competes directly with the Sellers’ Business (any such business, a “Competing Business”) or license any Excluded IP to any Person (other than Purchaser or its Affiliates) for use in or within the scope of the Sellers’ Business; provided, however, that it shall not be deemed to be a violation of this Section 5.12(a) for Seller or any of its Affiliates to, directly or indirectly, (i) invest in or own or hold any non-voting and non-convertible debt securities or other obligations of any Competing Business or (ii) invest in or own or hold any equity interest in any Competing Business so long as such Seller’s or such Affiliate’s investment or interest is less than five percent (5%) of the outstanding equity interests in such Competing Business, is a passive investment only, and Seller or such Affiliate does not exercise voting or other control over such Competing Business or participate directly in such Competing Business, and (iii) own any equity interests through any benefit plan or pension plan.

(b) From the date hereof until the second anniversary of the Closing Date, Sellers and each of their Affiliates shall not hire or solicit for employment any employee of the Purchasers or their Affiliates or any of the Specified Employees; provided, however, the restrictions of this Section 5.12(b) shall not apply to (i) any general solicitation in any newspaper, website or other publication, or through any search firm engagement which, in any such case, is not directed or focused on personnel employed by Purchasers or (ii) the solicitation or hiring of any employee of Purchasers or their Affiliates, whose employment has been terminated by Purchasers or their Affiliates prior to the commencement of employment discussions with Seller or the applicable Affiliate.

(c) From the date hereof until the fifth (5th) anniversary of the Closing Date, Purchaser and its Affiliates shall not offer employment to or hire any Excluded Personnel.

Sellers shall, following the reasonable request thereof by Purchasers, seek and use their respective commercially reasonable efforts to arrange meetings and telephone conferences with material suppliers, customers, licensors, licensees or other business partners of Sellers as may be reasonably requested by Purchaser and necessary and appropriate for Purchaser to coordinate transition of such Persons following the Closing.

Section 5.16 Separation and Transition of the Excluded Business. Sellers shall use commercially reasonable best efforts to obtain such services and support, including without limitation engineering support services, supply arrangements for fuel cells and future manufacturing services, as may be necessary for the Excluded Business to operate as a stand-alone business after the Closing.

The Party responsible under applicable Law for filing a Tax Return relating to such Transfer Taxes shall prepare and file such Tax Return and promptly provide a copy of such Tax Return to A123 Systems or Wanxiang, as applicable. If any Purchaser remits to the appropriate Governmental Authority payment for Transfer Taxes which are subject to this Section 7.4(a) in connection with filing any such Tax Returns on behalf of and at the request of the Sellers, the Sellers shall promptly reimburse such Purchaser for such Transfer Taxes upon written notice from such Purchaser.

(b) Purchase Price Allocation. No later than 90 days following the Closing Date, the Purchasers shall provide the Sellers with a proposed allocation of the Purchase Price and the Assumed Liabilities among the Purchased Assets. If the Sellers do not deliver a written notice disagreeing with the Purchasers’ proposed allocation within 30 days following the Sellers’ receipt thereof, the proposed allocation shall be final. If the Sellers deliver a written notice disagreeing with the Purchasers’ proposed allocation within 30 days following the Sellers’ receipt thereof, the Parties shall use commercially reasonable efforts to resolve such dispute within 30 days following the date of the dispute notice. If the Sellers and the Purchasers are unable to resolve such dispute within such 30-day period, they shall refer such dispute to an independent accounting firm or appraisal firm jointly selected by the Parties, whose determination shall be final and binding on the Sellers and the Purchasers for all purposes of this Agreement. The final allocation of the Purchase Price and the Assumed Liabilities among the Purchased Assets, determined in accordance with this Section 7.4(b), shall be set forth on a written schedule (the “Allocation Schedule”). The expenses, fees and costs of the independent accounting firm or appraisal firm shall be shared equally between the Sellers, on the one hand, and the Purchasers, on the other hand. The Sellers and the Purchasers agree to prepare and file any Tax Returns required to be filed with any taxing authority (including Internal Revenue Service Form 8594 and any comparable form under state, local, or foreign law) in accordance with the Allocation Schedule, except to the extent otherwise required pursuant to a “determination” within the meaning of Section 1313(a) of the Code (or any comparable provision of state, local or foreign law). Purchasers and Sellers shall not take any position contrary thereto or inconsistent therewith in any audits or examinations by any Governmental Authority or any other proceeding; provided, however, that nothing contained herein shall prevent Purchasers or Sellers from settling any proposed deficiency or adjustment by any Governmental Authority based upon or arising out of the Allocation Schedule and neither Purchasers nor Sellers shall be required to litigate before any court any proposed deficiency or adjustment by any Governmental Authority challenging such Allocation Schedule.

(c) Property Taxes.

(e) Cooperation. The Purchasers and the Sellers shall furnish or cause to be furnished to each other, as promptly as reasonably practicable, such information in their possession and assistance relating to the Sellers’ Business, the Purchased Assets and the Assumed Liabilities as is reasonably necessary for the preparation and filing of any Tax Return, claim for refund or other filings relating to Tax matters, or in connection with any Tax audit or other Tax proceeding.

(f) Certain Other Tax Matters. From the date hereof until the Closing:

In addition, the Sellers shall keep Wanxiang timely and reasonably apprised of any Action in respect of Taxes of the Foreign Subsidiaries.

(ii) With respect to any Tax Returns required to be filed prior to the Closing by or on behalf of the Foreign Subsidiaries or the Joint Venture (the “Specified Tax Returns”), the Sellers shall prepare, or shall cause to be prepared, all such Specified Tax Returns in a manner consistent with past practice and this Agreement. Sellers shall deliver, or cause to be delivered all such Specified Tax Returns to Wanxiang at least thirty (30) days prior to the due date for filing such Specified Tax Returns (taking into account any valid extensions) for Wanxiang’s review and comment, and, after revising such Specified Tax Returns to reflect any comments received from Wanxiang, Sellers shall timely file, or cause to be timely filed, such Specified Tax Returns. With respect to

the Specified Tax Returns of the Joint Venture, the Sellers shall be obligated to take the actions otherwise required under this Section 7.4(f)(ii) solely to the extent the Sellers or any other A123 Entity is entitled to do so under the relevant organizational documents of the Joint Venture,

(iii) Purchasers shall prepare and timely file or cause to be prepared and timely filed all Tax Returns of the Foreign Subsidiaries for the Straddle Period that are required to be filed after the Closing Date.

Subject to the provisions set forth in the preceding sentence, there shall be no liability or obligation thereafter on the part of any Party. Notwithstanding anything contained herein to the contrary, the termination of this Agreement shall not affect the rights or obligations of the Parties under the Confidentiality Agreement; provided that (i) from and after the date hereof, the provisions contained in the eighth, ninth and tenth paragraphs thereof shall be of no further force and effect and (ii) from and after the Closing Date, any information relating to the Purchased Assets shall not be deemed “Evaluation Material” under the Confidentiality Agreement.

Each Seller agrees and acknowledges that remedies at Law for any breach of its obligations under this Section 8.2 are inadequate and that, in addition thereto, Purchasers shall be entitled to equitable relief, including injunction and specific performance, in the event of any such breach, without necessity of demonstrating the inadequacy of money damages.

Section 8.3 Seller Remedies.

(a) RESERVED

(b) RESERVED

(d) If this Agreement is terminated pursuant to Section 8.1(j), Purchasers shall forfeit the CFIUS Deposit and any interest thereon and same shall be delivered to Sellers pursuant to Section 2.10(d). The receipt of the CFIUS Deposit shall be the sole and exclusive remedy of Sellers in connection with the failure of the Closing to occur and for any breach or default of Purchasers of this Agreement (other than (i) prior to the termination of this Agreement, specific performance and (ii) with respect to any covenant or agreement required by this Agreement to be performed by Purchasers after the Closing), and Sellers shall irrevocably waive and release the Purchaser Parties (as defined in Section 8.3(e)), as a condition to receipt of the CFIUS Deposit (but subject to the receipt thereof), from any and all statutory, equitable, legal or common law claims or remedies that any Seller may have against any of the Purchaser Parties in respect of any failure of the Closing to have occurred or any breach of or default under this Agreement; provided, however, that nothing in this Section 8.3(d) shall limit the amount of

Damages Sellers may recover as a result of failure by Purchasers to comply with a court order directing Purchasers to specifically perform their obligations under Section 5.8(d).

(e) If this Agreement is terminated pursuant to Section 8.1(d) or Section 8.1(k), Purchasers shall forfeit the Purchase Price Deposit and any interest thereon and deliver same to Sellers pursuant to Section 2.10(b). The receipt of the Purchase Price Deposit shall be the sole and exclusive remedy of Sellers for any breach or default of Purchasers of this Agreement (other than (i) prior to the termination of this Agreement, specific performance and (ii) with respect to any covenant or agreement required by this Agreement to be performed by Purchasers after the Closing), and Sellers shall irrevocably waive and release the Purchaser Parties, as a condition to receipt of the Purchase Price Deposit (but subject to the receipt thereof), from any and all statutory, equitable, legal or common law claims or remedies that any Seller may have against any of the Purchaser Parties in respect of any breach of or default under this Agreement; provided, however, that nothing in this Section 8.3(e) shall limit the amount of Damages Sellers may recover as a result of failure by Purchasers to comply with a court order directing Purchasers to specifically perform their obligations under Section 5.8(d). For purposes hereof, “Purchaser Parties” shall mean, collectively, the Purchasers and any of their respective former, current or future directors, officers, employees, agents, general or limited partners, managers, members, stockholders, Affiliates or assignees or any former, current or future director, officer, employee, agent, general or limited partner, manager, member, stockholder, Affiliate or assignee of any of the foregoing.

(f) The Parties acknowledge that the agreements contained in this Section 8.3 are an integral part of the transactions contemplated in this Agreement, that the damages resulting from termination of this Agreement under circumstances where Sellers are entitled to the Purchase Price Deposit are uncertain and incapable of accurate calculation and that the delivery of the Purchase Price Deposit is not a penalty but rather shall constitute liquidated damages in a reasonable amount that will compensate Sellers in the circumstances where Sellers are entitled to the Purchase Price Deposit for the efforts and resources expended and opportunities foregone while negotiating this Agreement and in reliance on this Agreement and on the expectation of the consummation of the Transactions contemplated hereby, and that, without these agreements, Sellers would not enter into this Agreement. If the Purchasers fail to take any action necessary to cause the delivery of the Purchase Price Deposit pursuant to the Deposit Escrow Agreement under circumstances where Sellers are entitled to the Purchase Price Deposit and, in order to obtain such Purchase Price Deposit, Sellers commence a suit which results in a judgment in favor of Sellers, the Purchasers shall pay to the Sellers an amount in cash equal to the costs and expenses (including reasonable attorney’s fees) incurred by Sellers in connection with such suit.

(g) Notwithstanding anything to the contrary contained in this Agreement, in no event and under no circumstances shall Purchasers forfeit, as a result of termination of this Agreement or otherwise, both the Purchase Price Deposit and the CFIUS Deposit, it being agreed that, except to the extent both the Purchase Price Deposit and the CFIUS Deposit are applied at the Closing towards the Purchase Price, if the Sellers are entitled to receive the Purchase Price Deposit pursuant to this Agreement, they shall not be entitled to receive the CFIUS Deposit, and if Sellers are entitled to receive the CFIUS Deposit they shall not be entitled to receive the Purchase Price Deposit, and concurrently with the Company receiving either the CFIUS Deposit

or the Purchase Price Deposit, in accordance with the terms of this Agreement and other than the case that both the Purchase Price Deposit and the CFIUS Deposit are applied at the Closing toward the Purchase Price, the other amount shall be delivered to Purchasers.

ARTICLE IX

INDEMNIFICATION

Section 9.1 Survival. All representations and warranties of any of the Sellers contained herein shall survive the Closing until the date that is nine (9) months after the Closing Date (the “Survival Date”). No Indemnification Claim (as defined below) may be asserted pursuant to Section 9.2 unless the applicable Notice of Claim (as defined below) is received by A123 Systems on or prior to the Survival Date (it being agreed and understood that if a claim for a breach of representation or warranty is timely made, the representation or warranty shall, solely for the purposes of such claim, survive until the date on which such claim is finally liquidated or otherwise resolved). No representations and warranties of the Purchasers contained herein shall survive beyond the Closing Date. This Section 9.1 shall not limit any Party’s liability for fraud.

Section 9.2 Indemnification of Purchaser. On and after the Closing Date, and subject to the other provisions of this Article IX (including the last sentence of this Section 9.2), each of the Purchaser Indemnitees shall be indemnified and held harmless from and against any and all claims, demands, suits, Actions, causes of actions, losses (including loss of profits, internal costs, loss of revenue and lost sales), costs, damages, liabilities and out-of-pocket expenses incurred or paid, including reasonable attorneys’ fees (including such fees which are incurred in connection with a good-faith dispute of the provisions of this Agreement), fines, penalties, costs of investigation or settlement, other professionals’ and experts’ fees, and court or arbitration costs (but specifically excluding any punitive, exemplary, special or speculative damages except to the extent such damages specifically excluded herein are awarded to a Third Party) (hereinafter collectively referred to as “Damages”), to the extent such Damages are suffered by a Purchaser Indemnitee and arise out of, are the reasonably foreseeable result of, or are caused by:

(a) any facts or circumstances that constitute an inaccuracy, misrepresentation or breach of any of the Sellers’ representations or warranties in Section 4.1;

(b) the breach of, default in, or failure to perform any covenant, agreement or other obligation of the Sellers set forth in this Agreement;

(c) any Excluded Asset or Excluded Liabilities (it being understood that in no event shall the Purchasers acquire any Excluded Assets or assume any Excluded Liabilities); or

(d) if the transactions contemplated hereby are consummated prior to receipt of CFIUS Approval using the trust structure described in Section 6.1(k)(ii), any failure by Sellers to remove any ITAR-Controlled Assets from the assets that are conveyed to Purchaser at Closing;

provided, however, that the Purchaser Indemnitees shall not be entitled to any indemnification pursuant to clause (a) of this Section 9.2 unless and until the total amount of Damages for all

Indemnification Claims for which the Purchaser Indemnitees are entitled to be indemnified under clause (a) of this Section 9.2 exceeds One Million Dollars ($1,000,000), in which case the Purchaser Indemnitees shall be entitled to all such Damages indemnifiable hereunder but in no event shall indemnification in respect of such Damages exceed the Indemnification Escrow Amount applicable at such time. The Purchaser, on behalf of itself and each other Purchaser Indemnitee, acknowledges and agrees that the Indemnification Escrow Account is the sole and exclusive source of funding for any Indemnification Claims and under no circumstances shall any Purchaser Indemnitees be entitled to indemnification in respect of Damages for such Indemnification Claims other than from the Indemnification Escrow Account, except to the extent Damages are incurred as a result of actual fraud of the Sellers under this Agreement, with respect to which the limitations set forth in this sentence shall not apply. For purposes of determining whether any indemnification is provided under clauses (a) or (b) of this Section 9.2, representations, warranties, covenants, agreements or other obligations set forth in this Agreement or in the Transaction Documents shall be read without giving effect to any materiality, knowledge or “material adverse effect” qualifiers in such provisions.

Section 9.3 Notice of Claim.

(a) Promptly after any Purchaser Indemnitee actually learns of any event or circumstance (including any Action instituted or asserted by a Third Party (a “Third Party Claim”) against any Purchaser Indemnitee) that is reasonably likely to give rise to indemnification under Section 9.2 (an “Indemnification Claim”), the Purchaser Indemnitee shall deliver to A123 Systems and such other Seller as Purchaser shall determine (the “Primary Seller Parties”) a notice executed by the Purchaser Indemnitee setting forth in reasonable detail the matter giving rise to the Indemnification Claim hereunder (such notice, a “Notice of Claim”). The Purchaser Indemnitee shall have the right to amend any Notice of Claim at any time.

(b) No delay on the part of any Purchaser Indemnitee in giving a Notice of Claim shall limit or reduce such Person’s right to indemnity hereunder, or relieve the Sellers from any of their obligations under this Article IX, unless (and then only to the extent that) the Sellers are actually prejudiced thereby.

Section 9.4 Resolution of Notice of Claim. Each Notice of Claim given by any Purchaser Indemnitee shall be resolved as follows:

(a) Admitted Claims. If the Primary Seller Parties agree in writing that liability for an Indemnification Claim is indemnified under Article IX for the full amount of the Damages specified in the Notice of Claim or amendment to Notice of Claim, or fail to give the Purchaser Indemnitee written notice contesting all or any portion of a Notice of Claim within thirty (30) days after such Notice of Claim (or amendment to any such Notice of Claim) is properly delivered to each of the Primary Seller Parties pursuant to Section 9.3 of this Agreement, then the Sellers shall be conclusively deemed to have consented to the recovery (subject to the limitations set forth in Section 9.2) by the Purchaser Indemnitee of the lesser of (i) the full amount of Damages actually incurred by such Purchaser Indemnitee in respect of such Indemnification Claim and (ii) the estimate of the anticipated Damages, if any, specified in such Notice of Claim or amendment thereto, as applicable.

(b) Contested Claims. With respect to any Notice of Claim not involving a Third Party Claim, if the Primary Seller Parties give the Purchaser Indemnitee written notice contesting all or any portion of a Notice of Claim or any amendment to a Notice of Claim, but solely with respect to any matters subject to such amendment (a “Contested Claim”) within thirty (30) days after proper delivery to the Primary Seller Parties of such Notice of Claim or amendment thereto pursuant to Section 9.3, then such Contested Claim shall be resolved by either (i) a written settlement agreement executed by the Primary Seller Parties and the Purchaser Indemnitee or (ii) in the absence of such a written settlement agreement within thirty (30) days of the Sellers’ delivery of a notice contesting the Notice of Claim or amendment thereto, all Indemnification Claims that are the subject of such Notice of Claim or the amendment thereto shall be resolved by a hearing of the U.S. Bankruptcy Court. The foregoing dispute resolution procedures shall also apply with respect to any disputes as between the Sellers, on the one hand, and the Purchaser or the Purchaser Indemnitees, on the other, over whether the Purchaser Indemnitees are entitled to indemnification for Damages resulting from a Third Party Claim.

(c) Participation in Defense of Third Party Claims. In the event of a Third Party Claim against any Purchaser Indemnitee for which an Indemnification Claim has been made, the Sellers may, at their option, participate in the defense of the Purchaser Indemnitee against the claims giving rise to such Third Party Claim (including through the employment of its choice of counsel, who shall be reasonably satisfactory to such Purchaser Indemnitee, it being understood that the Sellers shall be responsible for the payment of the fees, charges and disbursements of such counsel); provided that (i) such participation shall not limit the Purchaser Indemnitees’ control of such Third Party Claim and (ii) the Sellers and their counsel shall cooperate with the Purchaser Indemnitees and their counsel in connection with such Third Party Claim. The applicable Purchaser Indemnitee(s) shall have the right to undertake, conduct and control, through counsel of its own choosing and at its own expense (without prejudice to its right to recover all Damages in accordance with this Article IX), the defense of any Third Party Claim. Notwithstanding anything to the contrary, in the event of any Third Party Claim in respect of Taxes against the Sellers or their respective Affiliates that could reasonably be expected to adversely affect the Sellers’ Business, the Purchased Assets or the Purchasers or their respective Affiliates (a “Specified Third Party Tax Claim”), the Sellers shall keep the Purchasers timely and reasonably apprised of the status of such Specified Third Party Tax Claim.

(d) Settlement of Third Party Claims. In the event that a Purchaser Indemnitee shall compromise or settle any Third Party Claim without the consent of A123 Systems (which consent shall not be unreasonably withheld, delayed or conditioned), such compromise or settlement shall not be dispositive with respect to the Damages payable to such Purchaser Indemnitee in respect of such Third Party Claim but in no event shall the Damages payable from the Indemnification Escrow Account to such Purchaser Indemnitee in respect of such Third Party Claim exceed the amount of such compromise or settlement. For so long as any amounts remain in the Indemnification Escrow Account and subject to appropriate confidentiality and privilege protections, in the event a Purchaser Indemnitee intends to compromise or settle multiple claims with a Third Party and one or more of such claims is a Third Party Claim against the Purchaser Indemnitee, the Purchaser shall inform A123 Systems, prior to seeking its consent to such settlement or compromise, of: (i) the amount of all claims; (ii) the aggregate amount of such settlements or compromises with the Third Party; and (iii) the amount of the settlement allocated to each claim. Notwithstanding anything to the contrary, the

Sellers shall not settle or compromise, or permit their respective Affiliates to settle or compromise, any Specified Third Party Tax Claim without the consent of Wanxiang, which shall not be unreasonably withheld.

(e) Cooperation. From and after the delivery of any Notice of Claim subject to appropriate confidentiality and privilege protections, the Sellers and the applicable Purchaser Indemnitees shall make reasonably available to the other party, as applicable, and their respective attorneys, accountants and representatives all pertinent information under its control relating to the applicable Indemnification Claim and amount of Damages incurred in connection therewith, and the Sellers shall cooperate and, in the case of a Third Party Claim against the Purchaser Indemnitees, render to the applicable Purchaser Indemnitees such assistance as such Purchaser Indemnitees may reasonably require in order to facilitate the proper and adequate defense of any such Third Party Claim (including granting the applicable Purchaser Indemnitees and their attorneys, accountants and representatives reasonable access, during normal business hours, to the personnel of the Sellers (including as witnesses or deponents at trial and during the discovery process) to the extent reasonably related to the applicable Indemnification Claim).

Section 9.5 Treatment of Indemnity Payments; No Duplication of Damages. All indemnification payments under this Article IX shall be treated as adjustments to the Purchase Price for all applicable Tax purposes, except as is otherwise required by applicable Law. No Purchaser Indemnitee shall be entitled to recover any amount due hereunder more than once in respect of the same Damages, including receipt of third-party insurance proceeds in respect of Damages indemnifiable under this Article IX. To this end, the amount of any Damage for which a Purchaser Indemnitee claims indemnification under this Agreement (A) shall be reduced by (i) the amount of any insurance proceeds actually received by such Purchaser Indemnitee with respect to such Damage, (ii) the amount of any Tax benefits actually realized with respect to such Damage and (iii) payments provided by Third Parties to the Purchaser Indemnitee with respect to such Damage, and (B) shall be increased by the actual Tax costs of the Purchased Indemnitee on the receipt of any indemnification payment.

Section 9.6 Release of Remaining Indemnification Escrow Account Funds. On the Closing Date, Purchasers and Sellers shall jointly instruct the escrow agent holding the Indemnification Escrow Amount to release to Sellers, as soon as reasonably practicable following the Survival Date, all remaining funds in the Indemnification Escrow Account, other than an amount of funds equal to the alleged Damages for which a Notice of Claim has been delivered pursuant to Section 9.3 (the “Claimed Funds”). Any Claimed Funds shall be released to Sellers immediately upon resolution of the applicable Indemnification Claims.

Section 9.7 Exclusive Remedy. Without limiting the Purchasers’ rights under Section 10.7, after the Closing, Purchasers’ sole and exclusive remedy against Sellers for any and all of the Purchasers’ claims and Damages under this Agreement shall be the rights of indemnification set forth in this Article IX only, and the Purchasers will have no other entitlement, remedy or recourse, whether in law or equity. This Section 9.7 will not operate to interfere with or impede the operation of the covenants contained in this Agreement that by their nature are required to be performed after the Closing.

Section 9.8 Right of Contribution. If the Purchaser Indemnitee receives any payment from Primary Seller Party in respect of any Damages pursuant to Section 9.2 and the Purchaser Indemnitee is entitled to recover all or a part of such Damages from a Third Party (a “Potential Contributor”) based on the underlying claim asserted against the Purchaser Indemnitee, the Purchaser Indemnitee shall, to the extent permitted by Law and any applicable Contract, assign such of its rights to recover such amounts against the Potential Contributor to permit the Primary Seller Party to recover from the Potential Contributor the amount of such payment.

· The license described above will be nonexclusive, irrevocable, fully paid-up, worldwide, and royalty-free, except that, to the extent that any Background Technology licensed to Licensee under the IP License Agreement is subject to royalty payments to a third party or maintenance costs borne by Wanxiang Sub or its Affiliates, then Licensee shall pay (on its own behalf and on behalf of its sublicensees) to Wanxiang Sub (i) a royalty fee equal to a proportionate share of any royalty fees payable by Wanxiang Sub and its Affiliates and (ii) a proportionate share of the maintenance costs borne by Wanxiang Sub and its Affiliates, as applicable, provided, that, in each case of clause (i) and (ii), such proportions shall be based on Licensee’s and its sublicensees’ relative use of such Background Technology.

· The initial term of the license shall be three years; provided, however, that upon Licensee’s request the Wanxiang Sub will negotiate in good faith an extension of the license for an additional seven years (or such shorter period as Licensee may request) at a commercially reasonable royalty rate.

· Licensee will have full rights to sublicense for the sole purpose of exploitation in the USG Business by Licensee.

· The license will be nontransferable, except that A123 shall have the right to transfer such license (once and only once) to a third party who is the successor in interest to the USG Business solely for the purpose of such business, in which case A123 shall cease to hold any right to such license. Any third-party transferee shall have the right to subsequently transfer such license with the prior written consent of the Wanxiang Sub, such consent not to be unreasonably withheld.

· The license to Licensee may be subject to such conditions as may be deemed necessary to protect any national security concerns related to the USG Business.

· Licensee shall agree not to bring any claim, suit, or proceeding against Wanxiang Sub or its Affiliates or any of their contractors or customers after the Closing Date alleging infringement or misappropriation of the Excluded IP or of Licensee’s Intellectual Property Rights in any improvements or modifications to, or developments based on, the Background Technology.
