CONTRACT PURCHASE AGREEMENT

This Contract Purchase Agreement is entered into as of September 13, 2011 by and between World Energy Solutions, Inc., a Delaware corporation (the “Buyer”), and Co-eXprise, Inc., a Delaware corporation (the “Seller”).

This Agreement contemplates a transaction in which the Buyer will purchase certain contracts from the Seller and perform the Seller’s obligations under those contracts.

Upon and subject to the terms and conditions of this Agreement, and in consideration of the representations, warranties and covenants in this Agreement contained, the Parties agree as follows (capitalized terms used in this Agreement will have the meanings ascribed to them in Article IX):

ARTICLE I

THE CONTRACT PURCHASE

1.1 Purchase and Sale of Contracts. The Buyer will purchase the Assigned Contracts listed on Schedule 1.1 from the Seller, and the Seller will sell, assign and deliver all of its right, title and interest in the Assigned Contracts to the Buyer, for the consideration specified in Section 1.3.

1.2 Assumption of Obligations. The Buyer will assume and become responsible for, from and after the Closing, only the Assumed Obligations.

1.3 Purchase Price. The Purchase Price to be paid by the Buyer for the Assigned Contracts will consist of $4,000,000 in cash.

1.4 The Closing.

(a) The Closing will take place remotely concurrently with the execution and delivery of this Agreement on the Closing Date. All transactions at the Closing will be deemed to take place simultaneously, and no transaction will be deemed to have been completed and no documents or certificates will be deemed to have been delivered until all other transactions are completed and all other documents and certificates are delivered.

(b) At the Closing:

(a) the Seller will deliver to the Buyer:

(1) an assignment and assumption agreement, substantially the form of the agreement attached as Exhibit A, and such other instruments of conveyance as the Buyer may reasonably request in order to effect the sale, transfer, conveyance and assignment to the Buyer of valid ownership of the Assigned Contracts;

(2) copies of all of the waivers, permits, consents, approvals, authorizations, registrations, filings and notices, which are required on the part of the Seller;

(3) documents evidencing the release or termination of all Security Interests on the Assigned Contracts, and copies of filed UCC termination statements with respect to all UCC financing statements evidencing Security Interests; and

(4) such other certificates and instruments (including certificates of good standing of the Seller in its jurisdiction of organization and the various foreign jurisdictions in which it is qualified, certificates of registration as an energy broker and/or aggregator in those jurisdictions, and a certificate as to the incumbency of officers and the adoption of authorizing resolutions) as Buyer will reasonably request in connection with the Closing.

(c) the Buyer will deliver to the Seller:

(1) such certificates and instruments (including a certificate of good standing of the Buyer in its jurisdiction of organization and a certificate as to the incumbency of officers and the adoption of authorizing resolutions) as Seller will reasonably request in connection with the Closing; and

(2) the Purchase Price, by (i) wire transfer or other delivery of $3,775,000 in immediately available funds to an account designated by the Seller, (ii) deposit of $150,000 in escrow pursuant to the Escrow Agreement attached as Exhibit B pending receipt of a consent by Allegheny County to the assignment of the Marketplace Sourcing Agreement: Energy between the Seller and Allegheny County, and (iii) deposit of $75,000 in escrow pursuant to the Escrow Agreement and subject to the terms of Section 1.6(b).

1.5 Allocation. The Buyer and the Seller agree to allocate the Purchase Price among the Assigned Contracts and the non-competition covenants set forth in Section 6.3 for all purposes (including financial accounting and tax purposes) in accordance with the allocation schedule attached as Schedule 1.5. Buyer and Seller agree to use the allocations determined pursuant to this Section 1.5 for all tax purposes, including without limitation, those matters subject to Section 1060 of the Code, and the Treasury regulations promulgated thereunder.

1.6 Post Closing Reimbursement and Adjustment.

(a) Reimbursement. The Seller will reimburse the Buyer in an amount equal to $129,775 in respect of invoices generated from September 1, 2011 to September 30, 2011. Seller shall remit such amount to Buyer by October 31, 2011.

(b) True-Up.

(i) The calculation of the Purchase Price was based, in part, on backlog associated with the Supplier Agreements calculated as set forth on Schedule 1.6 (“Backlog”). Backlog relates to contracts in force as of September 1, 2011 representing transactions between energy suppliers and end users of energy (customers) as outlined on Schedule 1.6 related to commodity brokerage assuming end users consume energy at projected levels. Within thirty (30) days following October 31, 2012 (the “True Up Date”), Buyer shall prepare and deliver to Seller a final determination of the Backlog as of the True Up Date (“Final Backlog”) and, based thereon, calculate the amount payable, if any, pursuant to this Section 1.6(b) (the “True Up Amount”), accompanied by such schedules as it has prepared to support each such determination. Seller shall be entitled to review any working papers, trial balances and similar materials relating to such statements prepared by or on behalf of Buyer.

(ii) Within thirty (30) days after receipt of such statements and schedules (the “Objection Period”), Seller must notify Buyer of any objections to Buyer’s determinations of the Final Backlog and True Up Amount, providing in reasonable detail the basis for such objections. In the event that Seller does not timely or properly notify Buyer within the Objection Period that Seller has any objections to such statements or Buyer’s calculation of the final True Up Amount, then the Final Backlog and True Up Amount shall be final and binding hereunder. In the event that Seller does notify Buyer, within the Objection Period, that Seller has any such objection, then Buyer and Seller shall attempt to resolve such disputed items. In the event Seller and Buyer are unable to resolve the disputed items within thirty (30) days after receipt by Buyer of Seller’s notice of dispute, the parties’ respective independent certified public accountants shall attempt to resolve the disputed items. In the event that such accounting firms are unable to resolve such disputed items within sixty (60) days of Seller’s notice of dispute, such disputed items shall be referred to such independent accounting firm as mutually agreed upon by Buyer and Seller or, in the absence of such agreement such independent accounting firm as Seller and Buyer’s respective accounting firms jointly appoint to finally resolve such disputed items (provided that such firm has not within the preceding thirty-six (36) months had a, and does not have a current or prospective, business relationship with Buyer or Seller, or any of their respective Affiliates. The determination of such accounting firm shall be made as promptly as possible and shall be final and binding upon the parties absent demonstrable error acknowledged by such accounting firm. Seller and Buyer each shall be permitted to submit such data and information to such accounting firm as such party deems appropriate. The parties shall share responsibility for the out-of-pocket expenses and fees incurred in connection with resolving such disputed items as follows: (A) if the accounting firm resolves the objections substantially in favor of Buyer’s position, Seller will be responsible for all of the fees and expenses of the accounting firm, (B) if the accounting firm resolves the objections substantially in favor of Seller’s position, Buyer will be responsible for all of the fees and expenses of the accounting firm; and (C) if the accounting firm neither resolves the objections in favor of Buyer’s position nor resolves the objections in favor of the Seller’s position, the fees and expenses of the accounting firm shall be allocated between, and paid fifty percent (50%) by Buyer and fifty percent (50%) by Seller.

(iii) If the actual Backlog received by the Buyer for the period beginning on October 1, 2011 and ending on September 30, 2012 is at least 95% but not more than 105% of the expected Backlog as reflected in Schedule 1.6, then the $75,000 deposited in escrow pursuant to Section 1.4(c)(2)(iii) will be released to Seller. For example: total Backlog from October 1, 2011 through September 30, 2012 is represented to be $1,483,545. If actual cash received from the customers listed on Schedule 1.6 for contracts in force as of the Closing Date is equal to or greater than $1,409,367 but less than $1,557,722, then the $75,000 deposited in escrow would be released to Seller. If actual Backlog received is less than 95% of expected Backlog, then the Seller will be responsible to refund the difference between the actual percentage achieved and 95% to the Buyer. Any amounts to be refunded by Seller to Buyer will first be deducted from the $75,000 amount in escrow. To the extent the amount to be refunded to Buyer is greater than the amount in escrow, Seller will make an additional payment to Buyer in the amount greater than $75,000. If actual Backlog received is greater than 105% of expected Backlog, then the Buyer will remit the difference to Seller for the amount actual backlog received exceeds 105%. For example, if actual Backlog received is $1,261,013, or 85% of expected Backlog, then Seller would owe the Buyer $148,354, representing the difference between the amount actually collected and $1,409,367. This amount due would first be satisfied out of the amount in escrow of $75,000, with the Seller making a payment of $73,354 to Buyer for the incremental difference. If actual Backlog received is $1,631,900, or 110% of expected Backlog, then Buyer would remit to Seller $74,178, and the full amount in escrow would be released to Seller. All calculations and amounts due hereunder will be made by November 30, 2012.

1.7 Further Assurances. At any time and from time to time after the Closing, at the request of the Buyer and without further consideration, the Seller will execute and deliver such other instruments of sale, transfer, conveyance and assignment and take such actions as the Buyer may reasonably require to more effectively transfer, convey and assign to the Buyer, and to confirm the Buyer’s rights to, title in and ownership of, the Assigned Contracts and to place the Buyer in actual possession and operating control thereof.

(a) The Seller has properly filed on a timely basis all material Tax Returns that it is and was required to file, and all such Tax Returns were true, correct and complete in all material respects. The Seller has properly paid on a timely basis all material Taxes that were due and payable, whether or not shown on its Tax Returns, except (i) for Taxes being contested in good faith for which the Seller has set aside adequate reserves or (ii) where an improper payment or non-payment would not have a Seller Material Adverse Effect. All material Taxes that the Seller is or was required by law to withhold or collect have been withheld or collected and, to the extent required, have been properly paid on a timely basis to the appropriate Governmental Entity except where failure to withhold or collect would not have a Seller Material Adverse Effect.

(b) No examination or audit of any Tax Return of the Seller by any Governmental Entity is currently in progress or, to the knowledge of the Seller, threatened or contemplated. The Seller has not been informed by any jurisdiction that the jurisdiction believes that the Seller was required to file any Tax Return that was not filed.

(c) The Seller is not a party to any litigation regarding Taxes.

(d) There are no Security Interests with respect to Taxes upon any of the Assigned Contracts, other than with respect to Taxes not yet due and payable. There is no basis for the assertion of any claim relating or attributable to Taxes with respect to any of the Assigned Contracts.

Section 2.8 of the Disclosure Schedule contains a list of all employees of the Seller that perform services for the Business who are a party to a non-competition agreement with the Seller. Copies of such agreements have previously been delivered to the Buyer. Each such agreement referenced in the two preceding sentences to which the Seller is a party will continue to be legal, valid, binding and enforceable and in full force and effect immediately following the Closing in accordance with its terms as in effect immediately prior to the Closing. For the avoidance of doubt, the non-competition agreements referred to herein are not being assigned to Buyer as a part of this Agreement; rather, Seller will enforce any such agreement on Buyer’s behalf upon request pursuant to Section 6.3.

The Seller has, at all times, conducted its business in compliance in all material respects with each applicable material law (including rules and regulations thereunder) of any federal, state, local or foreign government, or any Governmental Entity.

Each Permit is in full force and effect; the Seller is in compliance in all material respects with the terms of each Permit; and, to the knowledge of the Seller, no suspension or cancellation of any Permit is threatened and there is no basis for believing that any Permit will not be renewable upon expiration. Each Permit is assignable by the Seller to the Buyer without the consent or approval of any party and will continue in full force and effect immediately following the Closing.

2.11 Brokers’ Fees. The Seller has no liability or obligation to pay any fees or commissions to any broker, finder or agent with respect to the transactions contemplated by this Agreement.

(a) The Seller has not been suspended or debarred from bidding on contracts or subcontracts with any Governmental Entity; to the Knowledge of Seller, no such suspension or debarment has been threatened or initiated; and the consummation of the transactions contemplated by this Agreement will not result in any such suspension or debarment of the Seller. The Seller has not been or is now being audited or investigated by the United States Government Accounting Office, the United States Department of Defense or any of its agencies, the Defense Contract Audit Agency, the contracting or auditing function of any Governmental Entity with which it is contracting, the United States Department of Justice, the Inspector General of the United States Governmental Entity, or any prime contractor with a Governmental Entity; nor, to the Knowledge of the Seller, has any such audit or investigation been threatened. To the Knowledge of the Seller, there is no valid basis for (i) the suspension or debarment of the Seller from bidding on contracts or subcontracts with any Governmental Entity or (ii) any claim (including any claim for return of funds to the Government) pursuant to an audit or investigation by any of the entities named in the foregoing sentence. The Seller has no agreements, contracts or commitments which require it to obtain or maintain a security clearance with any Governmental Entity.

POST-CLOSING COVENANTS

6.1 Benefits. If (i) any of the Assigned Contracts or other assets or rights constituting Assigned Contracts may not be assigned and transferred by the Seller to the Buyer (as a result of either the provisions thereof or applicable law) without the consent or approval of a third party, (ii) the Seller has not obtained such consent or approval prior to the Closing and (iii) the Closing occurs nevertheless, then (A) such Assigned Contracts and/or other assets or rights will not be assigned and transferred by the Seller to the Buyer at the Closing and the Buyer will not assume the Seller’s liabilities or obligations with respect thereto at the Closing, (B) the Seller will use its Reasonable Best Efforts to obtain the necessary consent or approval as soon as practicable after the Closing, (C) upon the obtaining of such consent or approval, the Buyer and the Seller will execute such further instruments of conveyance (in substantially the form executed at the Closing) as may be necessary to assign and transfer such Assigned Contracts and/or other assets or rights (and the associated liabilities and obligations of the Seller) to the Buyer, and (D) from and after the Closing until the assignment of each such Assigned Contract pursuant to clause (C) above, Seller and Buyer will cooperate in a commercially reasonable manner to reach a mutually agreeable arrangement under which Buyer will obtain the full rights and benefits and assume the obligations of each of the Assigned Contracts until such required consents are obtained.

6.2 Proprietary Information. From and after the Closing, the Seller will not disclose or make use of (except to pursue its rights, under this Agreement or the Ancillary Agreements), and will use its Reasonable Best Efforts to cause all of its Affiliates not to disclose or make use of, any knowledge, information or documents of a confidential nature or not generally known to the public with respect to Assigned Contracts, the Business or the Buyer or its business (including the financial information, technical information or data relating to the Seller’s products and names of customers of the Seller), as well as filings and testimony (if any) presented in the course of any arbitration of a Dispute pursuant to Section 7.3 and the arbitral award and the Arbitrator’s reasons therefor relating to the same), except to the extent that such knowledge, information or documents with respect to Assigned Contracts or the Business (i) are currently used in the retained businesses of the Seller in a manner that will not breach Section 6.3(a), or (ii) will have become public knowledge other than through improper disclosure by any of the Seller or an Affiliate. Upon the request of the Buyer, the Seller will use Reasonable Best Efforts to enforce, for the benefit of the Buyer, all confidentiality, invention assignments and similar agreements between the Seller and any other party relating to the Assigned Contracts or the Business that are not Assigned Contracts.

6.3 Non-Competition.

(a) For a period of five (5) years after the Closing Date, the Seller will not, either directly or indirectly as an owner, partner, employer, investor, lender, consultant, or otherwise, (i) design, develop, manufacture, market, sell or license any product or provide any service anywhere in the world which is competitive with any product designed, developed (or under development), manufactured, sold or licensed or any service used solely with respect to the Business by the Seller within the three-year period prior to the Closing Date or (ii) engage anywhere in the world in any business competitive with the Business as conducted as of the Closing Date or during the three-year period prior to the Closing Date. Upon the request of the Buyer, and at Buyer’s sole cost and expense, the Seller will use Reasonable Best Efforts to enforce, for the benefit of the Buyer, all non-competition and similar agreements between the Seller and any other party that are not Assigned Contracts. For the avoidance of doubt, the conduct of the business of the mineral rights division of the Co-eXprise Energy MarketPlace and the use and sale of software that contains an energy procurement module and services supporting such module in connection therewith will not be deemed to be competitive with the Business, so long as energy procurement modules are sold as a part of a multi-module package and not individually.

(b) The Seller agrees that the duration and geographic scope of the non-competition provision set forth in this Section 6.2 are reasonable. If any court determines that the duration or the geographic scope, or both, are unreasonable and that such provision is to that extent unenforceable, the Parties agree that the provision will remain in full force and effect for the greatest time period and in the greatest area that would not render it unenforceable. The Parties intend that this non-competition provision will be deemed to be a series of separate covenants, one for each and every county of each and every state of the United States of America and each and every political subdivision of each and every country outside the United States of America where this provision is intended to be effective.

(c) The Seller will, and will use its Reasonable Best Efforts to cause its Affiliates to, refer all inquiries regarding the Business and the products and services related thereto to the Buyer.

6.4 Collection of Assigned Contract Revenues.

(a) None of the Supplier Agreements are being assigned to the Buyer. Instead, the Seller will use its reasonable Best Efforts to collect any and all amounts due the Seller pursuant to the Supplier Agreements. The Seller will direct all suppliers making payments pursuant to the Supplier Agreements to remit payment directly to a lockbox that will be established with Silicon Valley Bank pursuant to a lockbox agreement. The Seller agrees that it will forward promptly to the lockbox any monies, checks or instruments received by the Seller after the Closing Date (a) pursuant to Supplier Agreements with respect to the Assigned Contracts and (b) related to items invoiced or to be invoiced after October 1, 2011, as reflected in Schedule 1.6. The Seller hereby grants to the Buyer a power of attorney to endorse and cash any checks or instruments payable or endorsed to the Seller or its order which are received by the Buyer pursuant to Supplier Agreements and which relate solely to the Assigned Contracts.

(b) If and to the extent that after the Closing Date, Buyer collects revenue pursuant to the Assigned Contracts that relates to an invoice generated prior to September 1, 2011, Buyer shall remit such amounts to Seller within thirty days after the end of the calendar month in which such amounts were received along with such schedules it has prepared to support the determination of such amount. Seller shall have the right at its expense to examine those financial records of Buyer as may be reasonably necessary to confirm the accuracy of the schedules provided to Seller and any calculations or payments made by Buyer hereunder. The Buyer will afford Seller access to the records during normal business hours, upon reasonable advance notice given by the Seller, and subject to such reasonable limitations as the Buyer may impose to delete competitively sensitive or privileged information.

6.5 Availability of Records. Seller and Buyer will each make available to the other any records in the nonrequesting party’s custody or control for the purpose of preparing any financial statement or tax return or preparing for or defending any tax-related examination of the requesting party by any governmental body. The party requesting the records will reimburse the nonrequesting party for the reasonable out-of-pocket costs and expenses incurred by the nonrequesting party. The nonrequesting party will afford access to the records during normal business hours, upon reasonable advance notice given by the requesting party, and subject to such reasonable limitations as the nonrequesting party may impose to delete competitively sensitive or privileged information. Notwithstanding the foregoing, in no event shall either party have any obligation to retain records after the second anniversary of the Closing Date unless an Indemnification Claim has been made pursuant to Section 7.1 with respect to the subject matter of such records.

ARTICLE VII

INDEMNIFICATION

7.1 Indemnification by the Seller. The Seller will indemnify Buyer (and its officers, directors, employees, and Affiliates) in respect of, and hold the Buyer (and its officers, directors, employees, and Affiliates) harmless against, Damages incurred or suffered by the Buyer or any Affiliate thereof resulting from, relating to or constituting:

(a) any breach, as of the date of this Agreement or as of the Closing Date, of any representation or warranty of the Seller contained in this Agreement, any Ancillary Agreement or any other agreement or instrument furnished by the Seller to the Buyer pursuant to this Agreement; or

(b) any failure of the Seller to perform any covenant or agreement contained in this Agreement, any Ancillary Agreement or any agreement or instrument furnished by the Seller to the Buyer pursuant to this Agreement.

7.2 Indemnification by the Buyer. The Buyer will indemnify the Seller (and its officers, directors, employees, and Affiliates) in respect of, and hold the Seller (and its officers, directors, employees, and Affiliates) harmless against, any and all Damages incurred or suffered by the Seller or any Affiliate resulting from, relating to or constituting:

(a) any breach, as of the date of this Agreement or as of the Closing Date, of any representation or warranty of the Buyer contained in this Agreement, any Ancillary Agreement or any other agreement or instrument furnished by the Buyer to the Seller pursuant to this Agreement; or

(b) any failure of the Buyer to perform any covenant or agreement contained in this Agreement, any Ancillary Agreement or any other agreement or instrument furnished by the Buyer to the Seller pursuant to this Agreement.

7.3 Indemnification Claims.

(a) An Indemnified Party will give written notification to the Indemnifying Party of the commencement of any Third Party Action. Such notification will be given within 20 days after receipt by the Indemnified Party of notice of such Third Party Action, and will describe in reasonable detail (to the extent known by the Indemnified Party) the facts constituting the basis for such Third Party Action and the amount of the claimed damages. No delay or failure on the part of the Indemnified Party in so notifying the Indemnifying Party will relieve the Indemnifying Party of any liability or obligation under this Agreement except to the extent of any damage or liability caused by or arising out of such failure. Within 20 days after delivery of such notification, the Indemnifying Party may, upon written notice thereof to the Indemnified Party, assume control of the defense of such Third Party Action with counsel reasonably satisfactory to the Indemnified Party; provided that (i) the Indemnifying Party may only assume control of such defense if (A) it acknowledges in writing to the Indemnified Party that any damages, fines, costs or other liabilities that may be assessed against the Indemnified Party in connection with such Third Party Action constitute Damages for which the Indemnified Party will be indemnified pursuant to this Article VII and (B) the amount of damages claimed is less than or equal to the amount of Damages for which the Indemnifying Party is liable under this Article VII and (ii) the Indemnifying Party may not assume control of the defense of Third Party Action involving criminal liability or in which equitable relief is sought against the Indemnified Party. If the Indemnifying Party does not, or is not permitted under the terms of this Agreement to, so assume control of the defense of a Third Party Action, the Indemnified Party will control such defense. The Non-controlling Party may participate in such defense at its own expense. The Controlling Party will keep the Non-controlling Party advised of the status of such Third Party Action and the defense thereof and will consider in good faith recommendations made by the Non-controlling Party with respect thereto. The Non-controlling Party will furnish the Controlling Party with such information as it may have with respect to such Third Party Action (including copies of any summons, complaint or other pleading which may have been served on such party and any written claim, demand, invoice, billing or other document evidencing or asserting the same) and will otherwise cooperate with and assist the Controlling Party in the defense of such Third Party Action. The fees and expenses of counsel to the Indemnified Party with respect to a Third Party Action will be considered Damages for purposes of this Agreement if (i) the Indemnified Party controls the defense of such Third Party Action pursuant to the terms of this Section 7.3(a) or (ii) the Indemnifying Party assumes control of such defense and the Indemnified Party reasonably concludes that the Indemnifying Party and the Indemnified Party have conflicting interests or different defenses available with respect to such Third Party Action. The Indemnifying Party will not agree to any settlement of, or the entry of any judgment arising from, any Third Party Action without the prior written consent of the Indemnified Party, which will not be unreasonably withheld, conditioned or delayed. The Indemnified Party will not agree to any settlement of, or the entry of any judgment arising from, any such Third Party Action without the prior written consent of the Indemnifying Party, which will not be unreasonably withheld, conditioned or delayed.

(b) In order to seek indemnification under this Article VII, an Indemnified Party will deliver a Claim Notice to the Indemnifying Party.

(c) Within 20 days after delivery of a Claim Notice, the Indemnifying Party will deliver to the Indemnified Party a Response, in which the Indemnifying Party will: (i) agree that the Indemnified Party is entitled to receive all of the Claimed Amount and arrange for immediate payment of the Claimed Amount to the Indemnified Party by check or by wire transfer, (ii) agree that the Indemnified Party is entitled to receive the Agreed Amount (if during the 20-day period following the delivery of a Claim Notice the Indemnifying Party and the Indemnified Party have negotiated an Agreed Amount) and arrange for immediate payment of the Agreed Amount to the Indemnified Party by check or by wire transfer; or (iii) dispute that the Indemnified Party is entitled to receive any of the Claimed Amount.

(d) During the 30-day period following the delivery of a Response that reflects a Dispute, the Indemnifying Party and the Indemnified Party will use good faith efforts to resolve the Dispute. If the Dispute is not resolved within such 30-day period, the Indemnifying Party and the Indemnified Party will discuss in good faith the submission of the Dispute to binding arbitration, and if the Indemnifying Party and the Indemnified Party agree in writing to submit the Dispute to such arbitration, then the provisions of Section 7.3(e) will become effective with respect to such Dispute. The provisions of this Section 7.3(d) will not obligate the Indemnifying Party and the Indemnified Party to submit to arbitration or any other alternative dispute resolution procedure with respect to any Dispute, and in the absence of an agreement by the Indemnifying Party and the Indemnified Party to arbitrate any Dispute, such Dispute will be resolved in a state or federal court sitting in the Commonwealth of Massachusetts, in accordance with Section 10.12.

(e) If, as set forth in Section 7.3(d), the Indemnified Party and the Indemnifying Party agree to submit any Dispute to binding arbitration, the arbitration will be conducted by the Arbitrator in accordance with the Commercial Rules in effect from time to time and the following provisions.

(a) If there is a conflict between the Commercial Rules in effect from time to time and the provisions of this Agreement, the provisions of this Agreement will prevail and be controlling.

(b) The parties will commence the arbitration by jointly filing a written submission with the office of the AAA having responsibility for matters to be arbitrated in Boston, Massachusetts, in accordance with Commercial Rule 5 (or any successor provision).

(c) No depositions or other discovery will be conducted in connection with the arbitration.

(d) Not later than 30 days after the conclusion of the arbitration hearing, the Arbitrator will prepare and distribute to the parties a writing setting forth the arbitral award and the Arbitrator’s reasons therefor. Any award rendered by the Arbitrator will be final, conclusive and binding upon the parties, and judgment thereon may be entered and enforced in any court of competent jurisdiction (subject to Section 10.12), provided that the Arbitrator will have no power or authority to grant injunctive relief, specific performance or other equitable relief.

(e) The Arbitrator will have no power or authority, under the Commercial Rules or otherwise, to (x) modify or disregard any provision of this Agreement, including the provisions of this Section 7.3(e), or (y) address or resolve any issue not submitted by the parties.

(f) In connection with any arbitration proceeding pursuant to this Agreement, each party will bear its own costs and expenses, except that the fees and costs of the AAA and the Arbitrator, the costs and expenses of obtaining the facility where the arbitration hearing is held, and such other costs and expenses as the Arbitrator may determine to be directly related to the conduct of the arbitration and appropriately borne jointly by the parties (which will not include any party’s attorneys’ fees or costs, witness fees (if any), costs of investigation and similar expenses) will be shared equally by the Indemnified Party and the Indemnifying Party.

(f) Notwithstanding the other provisions of this Section 7.3, if a third party asserts (other than by means of a lawsuit) that an Indemnified Party is liable to such third party for a monetary or other obligation which may constitute or result in Damages for which such Indemnified Party may be entitled to indemnification pursuant to this Article VII, and such Indemnified Party reasonably determines that it has a valid business reason to fulfill such obligation, then (i) such Indemnified Party will be entitled to satisfy such obligation, without prior notice to or consent from the Indemnifying Party, (ii) such Indemnified Party may subsequently make a claim for indemnification in accordance with the provisions of this Article VII, and (iii) such Indemnified Party will be reimbursed, in accordance with the provisions of this Article VII, for any such Damages for which it is entitled to indemnification pursuant to this Article VII (subject to the right of the Indemnifying Party to dispute the Indemnified Party’s entitlement to indemnification, or the amount for which it is entitled to indemnification, under the terms of this Article VII).

7.4 Survival of Representations and Warranties. The representations and warranties of the Parties will survive the Closing of this Agreement. No party will be entitled to assert any claim against the other party for misrepresentations, or breaches of warranties, under this Agreement unless the applicable Indemnified Party asserting such claim notifies the Indemnifying Party in writing of such claim on or prior to the first anniversary of the Closing Date; provided, that the one-year limitation on claims will not apply to any representation or warranty in this Agreement or in any Ancillary Agreement, as the case may be, in respect of or pursuant to any of Sections 2.1, 2.2 and 2.5 (the “Specified Representations”), which will survive without limitation. The rights to indemnification set forth in this Article VII will not be affected by (i) any investigation conducted by or on behalf of an Indemnified Party or any knowledge acquired (or capable of being acquired) by an Indemnified Party, whether before or after the Closing Date, with respect to the inaccuracy or noncompliance with any representation, warranty, covenant or obligation which is the subject of indemnification under this Agreement or (ii) any waiver by an Indemnified Party of any closing condition relating to the accuracy of any representations and warranties or the performance of or compliance with agreements and covenants.

7.5 Exclusive Remedy. Except with respect to claims based on fraud, after the Closing, the rights of the Indemnified Parties under this Article VII will be the exclusive remedy of the Indemnified Parties with respect to claims resulting from or relating to any misrepresentation, breach of warranty or failure to perform any covenant or agreement contained in this Agreement. Notwithstanding the foregoing, neither Seller, on the one hand, nor Buyer, on the other hand, will have any liabilities under or pursuant to this Agreement for any misrepresentations or breaches of warranties under this Agreement until such liabilities exceed in the aggregate One Hundred Seventy-Five Thousand US Dollars (US$175,000) (the “Basket Amount”), at which time such indemnifying party(ies) will be fully liable for all such liabilities in excess of the Basket Amount. The maximum aggregate indemnification obligation of Seller under this Agreement will not, except in the case of fraud or intentional misrepresentation, exceed (i) an amount equal to 50% of the Purchase Price or (ii) in connection with breaches of the Specified Representations, the aggregate Purchase Price. In no event will the indemnification obligations of the Seller under this Agreement exceed one hundred percent (100%) of the Purchase Price actually received by the Seller.

7.6 Treatment of Indemnity Payments. Any payments made to an Indemnified Party pursuant to this Article VII will be treated as an adjustment to the Purchase Price for tax purposes.
