21

assurance as may be required under Section 365 of the Bankruptcy Code.  Sellers shall be solely responsible for the payment, performance and discharge when due of the Liabilities under the Assumed Contracts and the Assumed Lease arising and coming due prior to the Closing Date that constitute Excluded Liabilities.

(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 the Purchaser 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 Purchaser 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 the Purchaser 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 the Purchaser 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 the Purchaser following the Closing but in any event no later than the date that is ninety (90) days after the Closing pursuant to this Section 2.7(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 the Purchaser, 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 2.7(b) and the Purchaser shall pay or reimburse Sellers for all costs and expenses incurred in connection with maintaining, and providing the Purchaser the benefits of use of such asset.

(d)           If, following the Closing, the Purchaser receives or becomes aware that it holds any asset, property or right which constitutes an Excluded Asset, then the Purchaser shall transfer such asset, property or right to the Sellers as promptly as practicable for no additional consideration and shall deliver to Sellers all income, proceeds and other monies received by the Purchaser pursuant to such asset, property or right.

Section 2.9            Purchase Price Deposit.

(a)           Prior to the execution of this Agreement, the Purchaser deposited into escrow an earnest money deposit (the “Purchase Price Deposit”) in the amount of $400,000 as security for the performance of the Purchaser’s obligations under this Agreement.  The Purchase Price Deposit, together with any interest thereon, shall be applied against the Purchase Price at Closing in accordance with the Deposit Escrow Agreement.  Except as set forth in Section 2.9(b), if this Agreement shall be terminated pursuant to Section 8.1, the Purchase Price Deposit, together with any interest earned thereon, shall be delivered to the Purchaser in accordance with the terms of the Deposit Escrow Agreement.

(b)           If this Agreement is terminated by Sellers pursuant to Section 8.1(d) or Section 8.1(j), then, notwithstanding anything in the Deposit Escrow Agreement to the contrary, $250,000 of such Purchase Price Deposit (the “Partial Purchase Price Deposit Amount”) shall be delivered to the Sellers, and the remainder of such Purchase Price Deposit shall be delivered to the Purchaser.

(a)                                 Prior to the Closing, upon the terms and subject to the conditions of this Agreement, and except as contemplated by this Agreement, the Sale Procedures Order or the Sale Order, the Parties shall take, or cause to be taken, all actions, and to do, or cause to be done all things necessary, proper or advisable to consummate the Closing and the Transactions as promptly as reasonably practicable, including the preparation and filing of all forms, registrations and notices required pursuant to applicable Law to be filed to consummate the Closing and the Transactions and the taking of such actions as are necessary to obtain any requisite approvals, authorizations, Consents, releases, orders, licenses, Permits, qualifications, exemptions or waivers by any third party or Governmental Authority.  In furtherance of the foregoing, the Parties agree that as promptly as reasonably practicable following the execution of this Agreement, the Parties shall make all premerger notification filings required under the pre-merger notification rules in any jurisdiction in which the parties agree applicable Law requires a premerger notification filing (which filing shall be made promptly following such determination).  Subject to applicable Law, each such Party shall promptly inform the other Parties hereto of any oral communication with, and provide copies of written communication with, any Governmental Authority regarding any such filings.  No Party shall independently participate in any substantive meeting or discussion, either in person or by telephone, with any Governmental Authority in respect of any such filings, investigation, or other inquiry without giving the other parties hereto prior notice of the meeting and, to the extent permitted by such Governmental Authority, the opportunity to attend and/or participate.  Subject to applicable Law, the Parties will consult and cooperate with one another in connection with any analyses, appearances, presentations, memoranda, briefs, arguments, opinions and proposals made or submitted by or on behalf of any party hereto relating to proceedings under any antitrust law.  The Purchaser shall be responsible for and shall pay all fees in respect of any required premerger notification filings.

35

(b)                                 The Parties shall use their best efforts to take all reasonable steps (including committing to the divestiture of any assets or business of the Purchaser (or any Affiliate of the Purchaser) or any Purchased Assets or agreeing to limitations on the conduct of its business) as may be necessary to obtain an approval from, resolve any objection or assertion by any Governmental Authority or to resolve an action or proceeding by, any Governmental Authority, whether by judicial or administrative action, challenging this Agreement or the consummation of the Transactions or the performance of obligations hereunder under any antitrust law.

Section 5.5                                    Publicity.  Except as required by applicable Law (including any Order by the Bankruptcy Court) or filings by the Sellers with, or in any proceeding before, the Bankruptcy Court, neither Party shall, to the extent reasonably practicable, issue any press release, provide any notice to customers or suppliers, or make any public announcement concerning this Agreement or the Transactions without the other Party’s consent, not to be unreasonably withheld delayed or conditioned; provided that the Sellers may issue any such press release or make any such public announcement in connection with the Auction after having provided the Purchaser at least one (1) Business Day to review and comment on such release or announcement (which comments shall be reasonably considered by the Sellers).  Nothing in this Section 5.5 shall prohibit any Party from making any public statement without prior consultation of the other Party as may be required by applicable Law or by obligations pursuant to any listing agreement with any national securities exchange.

Section 5.6                                    Certain Matters Relating to Specified Employees.

(a)                                 The employees of Sellers and their Affiliates set forth on Schedule 5.6 are referred to collectively herein as the “Specified Employees” and are each individually referred to herein as a “Specified Employee.”  No later than ten (10) days after the date hereof, the Purchaser (x) intends to offer employment to each Specified Employee with respect to whom an asterisk appears next to his or her name on Schedule 5.6 (each, a “Designated Specified Employee,” collectively, the “Designated Specified Employees”) and (y) shall offer employment to each Specified Employee who is not also a Designated Special Employee, in each case, effective as of the Closing Date, each such offer to be made in a manner that does not give rise to severance under the severance plan, program, agreement or arrangement maintained for such Specified Employee by Sellers and shall include (i) employment principally located in the same general vicinity as the Specified Employee’s principal work location as of immediately prior to the Closing Date and, in any event, in a location that does not increase such Specified Employee’s one way commute as of immediately prior to the Closing Date by more than thirty (30) miles, (ii) comparable duties and responsibilities to such Specified Employee’s responsibilities with the Sellers as of immediately prior to the Closing Date, and (iii) provide for total annual cash compensation (including base salaries and target bonus opportunities) equal to or greater than the amounts provided by Sellers to such Specified Employee as of immediately prior to the Closing Date.  Each such Specified Employee who accepts an offer of employment from the Purchaser and commences employment with the Purchaser is referred to herein as a “Transferred Employee.”

(b)                                 Notwithstanding Section 5.6(a), nothing herein expressed or implied shall confer upon any of the employees of any Seller or any Transferred Employees any right to

36

employment or continued employment for any specified period, of any nature or kind whatsoever under or by reason of this Agreement.

(c)                                  Notwithstanding anything to the contrary in this Agreement, starting on the Closing Date, the Purchaser shall, for a period ending on the 24-month anniversary of the Closing Date, maintain a severance pay practice for the benefit of each Transferred Employee that is no less favorable than the severance pay practice provided by Sellers and their Affiliates in respect of such Transferred Employee as of immediately prior to the Closing Date.  The Purchaser shall assume and shall indemnify Sellers and their Affiliates against all liabilities and obligations to provide any payments, including, without limitation, severance and payment-in-lieu of notice, or benefits to (i) any Specified Employee who does not become a Transferred Employee and (ii) any Transferred Employee whose employment is terminated by the Purchaser following the Closing Date.

(d)                                 Except as provided in Section 5.6(c), neither the Purchaser, nor any Affiliate of the Purchaser 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, 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 the Purchaser’s request, Sellers shall reasonably provide the Purchaser 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 the Purchaser 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 reasonably requested by the Purchaser between the date hereof and the Closing, Sellers will promptly deliver notices complying with WARN to Service Providers with respect to whom such a request is made.

(e)                                  Effective upon the Closing Date, each of the Sellers hereby waives, for the benefit of the Purchaser 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.

(f)                                   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 the Purchaser 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 the Purchaser 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

37

level of benefits or participation, or (iii) to the extent that its application would result in a duplication of benefits with respect to the same period of service.  Following the Closing, the Purchaser 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.

(g)                                  Subject to applicable Laws, the Sellers shall cooperate with the Purchaser and shall permit the Purchaser a reasonable period during normal business hours prior to the Closing Date, (i) to meet with Service Providers at such times as the Purchaser 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), (iii) to distribute to Specified Employees such forms and other documents relating to employment by the Purchaser after the Closing, and (iv) subject to any restrictions imposed under applicable Law, to permit the Purchaser, upon request, to review personnel files and other relevant employment information regarding such Service Providers.

(h)                                 Following the Closing, the Sellers and the Purchaser shall cooperate reasonably with each other to provide an orderly administrative transition to the Purchaser of the Transferred Employees, including the provision by the Sellers to the Purchaser of copies of all reasonably necessary or appropriate documents, records, materials, accounting files and Tax information with respect to each Transferred Employee.

(i)                                     Nothing in this Section 5.6 shall (i) be treated or construed as an amendment of, or undertaking to amend, any benefit plan or (ii) be construed to prohibit the Purchaser or any of its Affiliates from amending or terminating any benefit plan.  The provisions of this Section 5.6 are solely for the benefit of the respective parties to this Agreement and nothing in this Section 5.6, 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 5.7                                    Non-Solicitation.  From the date hereof until the fifth (5th) anniversary of the Closing Date, the Purchaser and its Affiliates shall not offer employment to or hire any Excluded Personnel.

Section 5.8                                    Sales Process.  The Purchaser acknowledges that Sellers and their Representatives and Affiliates are and may continue to solicit inquiries, proposals or offers for

38

all or a portion of the Purchased Assets, pursuant to the terms of the Sales Procedures Order prior to and at the Auction.  Prior to and at the Auction, the Purchaser and any other Person that participates in the Auction may make offers that improve upon their respective prior offers to Sellers (including this Agreement).  If following the Hearing the Purchaser is not the Successful Bidder in the Auction, the Purchaser hereby commits to stand ready to consummate the Transactions set forth in this Agreement as may be amended by any Subsequent Bid submitted by the Purchaser in the Auction, and the Parties shall close the Transactions in accordance with the terms and conditions of this Agreement, as amended by any Subsequent Bid submitted by the Purchaser in the Auction, through and including the date that is the earlier of (i) twenty (20) days after entry of the Sale Order or (ii) the first Business Day following the consummation of the sale of the Purchased Assets to the Successful Bidder, after which date the Purchaser shall no longer be required to consummate such Transactions.

Section 5.9                                    Business Partners.  Following the Hearing, Sellers shall, upon the reasonable request thereof by the Purchaser, 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 the Purchaser and necessary and appropriate for the Purchaser to coordinate transition of such Persons following the Closing.  Prior to the Auction, the Purchaser shall not be permitted to contact any customers, suppliers, licensors, licensees or other business partners of Sellers about the Seller Chapter 11 Cases without Sellers’ prior consent (such consent not to be unreasonably withheld, delayed or conditioned), other than as part of the Chapter 11 proceedings.

Section 5.10                             Novation.  From and after the date hereof, the Parties shall take all commercially reasonable steps necessary as requested by any Governmental Authority to pursue final novation of the Assumed Contracts.

(b)                                 Purchase Price Allocation.  No later than 90 days following the Closing Date, the Purchaser 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 Purchaser’s 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 Purchaser’s 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 Purchaser 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 Purchaser 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 Purchaser, on the other hand.  The Sellers and the Purchaser agree to prepare and file any

43

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.  The Purchaser 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 the Purchaser or Sellers from settling any proposed deficiency or adjustment by any Governmental Authority based upon or arising out of the Allocation Schedule and neither the Purchaser 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.  The Sellers shall be responsible for any Property Taxes (including any special or supplemental assessments) with respect to any Purchased Asset allocable to any taxable period or portion thereof ending on or prior to the Closing Date (the “Pre-Closing Tax Period”) (without regard to when such Taxes are assessed or payable).  The Purchaser shall be responsible for any Property Taxes (including any special or supplemental assessments) with respect to any Purchased Asset allocable to any taxable period or portion thereof ending after the Closing Date (the “Post-Closing Tax Period”) (without regard to when such Taxes are assessed or payable).  If, following the Closing, one Party remits to the appropriate Governmental Authority payment for Property Taxes which are subject to this Section 7.4(c) and such payment includes the other Party’s share of such Property Taxes, such other Party shall promptly reimburse the remitting Party for its share of such Property Taxes upon written notice from such paying Party; provided that the Purchaser shall not be required to make any payment with respect to prepaid Property Taxes described in Section 2.1(a)(viii).  Any refund of Property Taxes which are subject to this Section 7.4(c) shall be allocated between the Sellers and the Purchaser in a manner consistent with this Section 7.4(c).  Property Taxes for any taxable period that commences prior to and includes (but does not end on) the Closing Date (a “Straddle Period”) shall be allocated between the Pre-Closing Tax Period and the Post-Closing Tax Period in proportion to the number of days in each such period.

(d)                                 Cooperation.  The Purchaser 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 USG Business, the Purchased Assets, the Transferred Employees 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.

(h)                                 by either the Sellers or the Purchaser, if a Governmental Authority of competent jurisdiction shall have issued a final and non-appealable Order or taken any other non-appealable final action, in each case, having the effect of permanently making the Transactions illegal or otherwise permanently restraining or prohibiting consummation of the Transactions;

(i)                                     by either the Sellers or the Purchaser if (i) the Auction has occurred and the Purchaser was not the Successful Bidder, (ii) the Bankruptcy Court otherwise approves a Competing Transaction with the Person that was the Successful Bidder, and (iii) such Competing Transaction is consummated; and

(j)                                    by the Sellers, if (i) all conditions to the Closing set forth in Article VI have been satisfied or waived (other than conditions that can only be satisfied as of the Closing) and nothing has occurred and no condition exists that would cause any of the conditions set forth in Article VI to fail to be satisfied, (ii) Sellers are willing and able to consummate the Closing, such matters to be confirmed in writing to the Purchaser by an executive officer of the Sellers, and (iii) the Purchaser fails to consummate the Closing within one (1) Business Day after the date the Closing should have occurred pursuant to Section 7.1.

Section 8.2                                    Effect of Termination.  In the event of any termination of this Agreement pursuant to Section 8.1, this Agreement (other than the provisions set forth in this Section 8.2, Section 8.3 and Article X and Sellers’ right to retain the Partial Purchase Price Deposit Amount in accordance with Section 2.9(b)) shall forthwith become null and void and be deemed of no further force and effect.  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 (a) 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 (b) from and after the Closing Date, any information relating to the Purchased Assets shall not be deemed “Evaluation Material” under the Confidentiality Agreement.

Section 8.3                                    Remedies Upon Termination.

(a)                                 If this Agreement is terminated pursuant to Section 8.1(c)(i), Sellers shall pay to the Purchaser the Reimbursable Expenses, which amount shall not exceed $1,000,000 and shall be paid no later than three (3) Business Days following such termination.

(b)                                 In the event of a termination of this Agreement by the Purchaser, the receipt of the Reimbursable Expenses, if applicable, shall be the sole and exclusive remedy of the Purchaser for any breach or default of Sellers of this Agreement (other than (i) prior to the termination of this Agreement, specific performance but only as expressly permitted under Section 10.7(b) and (ii) with respect to any covenant or agreement required by this Agreement to be performed by the Sellers after the Closing), and the Purchaser shall irrevocably waive and release the Seller Parties, from any and all statutory, equitable, legal or common law claims or remedies that the Purchaser may have against any of the Seller Parties in respect of any breach of or default under this Agreement, other than in the case of fraud.  For purposes hereof, “Seller Parties” shall mean, collectively, the Sellers and any of their respective former, current or future

46

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.

(c)                                  If this Agreement is terminated pursuant to Section 8.1(d) or Section 8.1(j), the Purchaser shall forfeit the Partial Purchase Price Deposit Amount and deliver same (or not object to the escrow agent holding the Partial Purchase Price Deposit Amount to deliver same) to Sellers pursuant to Section 2.9(b).  The receipt of the Partial Purchase Price Deposit Amount shall be the sole and exclusive remedy of Sellers for any breach or default of the Purchaser of this Agreement (other than (i) prior to the termination of this Agreement, specific performance but only as expressly permitted under Section 10.7(b) and (ii) with respect to any covenant or agreement required by this Agreement to be performed by the Purchaser after the Closing), and Sellers shall irrevocably waive and release the Purchaser Parties, as a condition to receipt of the Partial Purchase Price Deposit Amount (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, other than in the case of fraud.  For purposes hereof, “Purchaser Parties” shall mean, collectively, the Purchaser and any of its 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.

(d)                                 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 Partial Purchase Price Deposit Amount are uncertain and incapable of accurate calculation and that the delivery of the Partial Purchase Price Deposit Amount 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 Partial Purchase Price Deposit Amount 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 Purchaser fails to take any action necessary to cause the delivery of the Partial Purchase Price Deposit Amount pursuant to the Deposit Escrow Agreement under circumstances where Sellers are entitled to the Partial Purchase Price Deposit Amount and, in order to obtain such Partial Purchase Price Deposit Amount, Sellers commence a suit which results in a judgment in favor of Sellers, the Purchaser 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.

(a)                                 The Sellers acknowledge that the Purchaser would be damaged irreparably in the event that this Agreement is not performed by Sellers in accordance with its specific terms or is otherwise breached by the Sellers or the Sellers fail to consummate the Closing as required hereunder and that, in addition to any other remedy that the Purchaser may have under law or equity, the Purchaser shall be entitled to seek injunctive relief to prevent breaches of the terms of this Agreement and to seek to enforce specifically the terms and provisions hereof that are required to be performed by Sellers.

(b)                                 The Purchaser acknowledges that Sellers would be damaged irreparably in the event that this Agreement is not performed by the Purchaser in accordance with its specific terms or is otherwise breached by the Purchaser or the Purchaser fails to consummate the Closing as required hereunder and that, in addition to any other remedy that the Sellers may have under law or equity, the Sellers shall be entitled to seek injunctive relief to prevent breaches of the terms of this Agreement and to seek to enforce specifically the terms and provisions hereof that are required to be performed by the Purchaser.

WHEREAS, pursuant to the Purchase Agreement, the Sellers have agreed to assign, transfer, convey and deliver when due, any and all of the Purchased Assets, including the Assumed Contracts and the Assumed Lease (but not any of the Excluded Assets);

WHEREAS, pursuant and subject to the Purchase Agreement, the Purchaser has agreed to assume, honor, pay and discharge when due, any and all of the Assumed Liabilities (but not any of the Excluded Liabilities); and

WHEREAS, the execution and delivery of this Agreement by the Sellers and the Purchaser is a condition to the obligations of the parties to consummate the transactions contemplated by the Purchase Agreement;

NOW, THEREFORE, in consideration of the premises and the mutual agreements and covenants set forth in the Purchase Agreement and hereinafter set forth, the Sellers and the Purchaser hereby agree as follows:

1.                                      Assignment and Assumption of Liabilities.

(a)                                 The Sellers hereby assign, transfer, convey and deliver (i) all of the Sellers’ right, title and interest in and to the Purchased Assets, including the Assumed Contracts and the Assumed Lease, to [·], pursuant and subject to the Purchase Agreement and the Sale Order.

(b)                                 [·] does hereby assume, and agree to honor, pay and discharge when due, all of the Assumed Liabilities.

(c)                                  Notwithstanding the foregoing provisions of paragraph (b), [·] and [·] do not assume, or agree to pay, perform or otherwise discharge when due, any Liabilities of the Sellers other than the Assumed Liabilities, the Assumed Contracts and the Assumed Lease, including, without limitation, the Excluded Liabilities.

2.                                      Assignment of this Agreement.

Neither the Sellers nor the Purchaser may assign or otherwise transfer their respective rights and/or obligations hereunder (or agree to do so) without the prior written

consent of the other Parties; provided, that Purchaser may, without the consent of Sellers, assign or transfer any or all of its right and/or obligations hereunder to one or more of its Affiliates or other Persons (it being understood that the Purchaser nonetheless shall remain liable for the performance of all of the Purchaser’s obligations hereunder to the extent not performed by the assignee).  Any assignment or other transfer not permitted under this section shall be null and void ab initio.

3.                                      Further Assurances.

Subject to the provisions of this Agreement and the Purchase Agreement, each of the Parties hereto agrees to execute, acknowledge, deliver, file and record such further certificates, amendments, instruments and documents, and to do all such other acts and things, as may be reasonably requested by any other Party in order to carry out the intent and purpose of this Agreement at the expense of the requesting Party, provided that this shall not require any Party to take any action that is commercially unreasonable or that would result in any Liability of such Party or any of its Affiliates.

7.                                      Severability.

Any provision of this Agreement which is determined by a court of competent jurisdiction to be invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining provisions of this Agreement or affecting the validity or enforceability of any of the provisions of this Agreement in any other jurisdiction, and if any

provision of this Agreement is determined to be so broad as to be unenforceable, such provision shall be interpreted to be only so broad as is enforceable, provided in all cases that neither the economic nor legal substance of this Agreement is affected by the operation of this sentence in any manner materially adverse to any party.  Upon any such determination that any provision of this Agreement is invalid or unenforceable, the Parties shall negotiate in good faith in an effort to agree upon a suitable and equitable substitute provision to effect the original intent of the Parties.
