WHEREAS, the parties to the Power Contract and the Federal Energy Regulatory Commission (the "Commission"), which has regulatory jurisdiction over the Power Contract, have consistently recognized that the cost of the capacity and electric energy sold under the Power Contract necessarily included the costs of shutting down, removing from service and decommissioning the Plant after its useful life had ended and the parties have heretofore incorporated in the Power Contract provisions designed to achieve that

result, whether or not the Plant produced electricity and whether or not the Plant operated for the full term of the Facility Operating License; and

WHEREAS, Section 6 of the Power Contract allows Yankee to collect its costs of decommissioning the Plant from the Customer and the other stockholders of Yankee through accruals to a reserve fund, with accruals made over a period extending to December 31, 2010; and

WHEREAS, Section 11 of the Power Contract provides that, upon authorization by its board of directors of a uniform amendment to all customer power contracts, Yankee shall have the right to amend the provisions of Section 6 of the Power Contract by serving an appropriate statement of such amendment upon the Customer and filing the same with the Commission, and that the amendment shall thereupon become effective on the date specified therein, subject to any suspension order duly issued by such agency; and

WHEREAS, the parties to the Power Contract desire to amend Section 6 of the Power Contract to allow the collection of costs through accruals to extend beyond December 31, 2010, to a date approved by the board of directors so that the costs of decommissioning the Plant can be met through the fund.

NOW, THEREFORE, in consideration of the above, the parties hereto agree that the Power Contract is hereby amended as follows:

1. Terms used herein and not defined shall have the meanings set forth in the Power Contract.

2. The first sentence of the fourth paragraph of Section 6 of the Power Contract is hereby modified to read as follows:

Yankee's "operating expenses" shall include all amounts properly chargeable to operating expense accounts, less any applicable credits thereto, in accordance with the Uniform System; it being understood that for purposes of this contract "operating expenses" shall include (i) depreciation or amortization accrued at a rate at least sufficient to fully amortize over the estimated remaining useful life of the plant Yankee's non-salvageable investments in plant, nuclear fuel and materials and supplies or other assets, provided, however, that if a decision is made to cease electricity production at the plant prior to July 9, 2000, then such remaining non-salvageable investments shall be amortized over a period extending to July 9, 2000; (ii) obligations incurred in connection with the leasing of fuel inventory; (iii) interest charges not associated with outstanding indebtedness; and (iv) costs incurred in connection with decommissioning the plant, including (a) the direct and indirect costs of operating, maintaining or dismantling the spent fuel storage facilities and other plant facilities after the cessation of electricity production and (b) the accruals to any reserve established by Yankee's board of directors to provide for physical decommissioning of the plant over the estimated remaining useful life of the plant, provided, however, that if a decision is made to cease electricity production at the plant prior to July 9, 2000, then the accruals to the reserve referred to in clause (b) shall be made over a period determined by Yankee's board of directors.

3. This Amendment shall become effective as of the date first above written, subject to any order duly issued by the Federal Energy Regulatory Commission.

4. This Amendment may be executed in any number of counterparts, all of which together shall constitute one and the same instrument.

IN WITNESS WHEREOF, the parties hereto have caused their respective duly authorized representative to execute this Amendment on their behalf as of the date first above written.

Upon the determination of the Purchase Price Adjustment, the Party owing a balance on account of the Purchase Price Adjustment shall deliver the balance due to the other Party no later than two (2) Business Days after such determination in immediately available funds or in any other manner as reasonably requested by the payee.  The balance due shall be determined by offsetting against each Party’s credits and debits arising from the Purchase Price Adjustment the credits and debits accorded to each Party in the Closing Statement on account of the Estimated Adjustment.  The acceptance by Buyer and Seller of the Purchase Price Adjustment shall not constitute or be deemed to constitute a waiver of the rights of such Party in respect of any other provision of this Agreement.

If such an appraisal is made, both Buyer and Seller agree to accept the Independent Appraiser’s determination of the fair value of the Acquired Assets.  The cost of the appraisal shall be borne equally by Buyer and Seller.  Each of Buyer and Seller agrees to file Internal Revenue Service Form 8594 ("Form 8594") and all federal, state, local and foreign Tax Returns in accordance with such agreed allocation (giving effect to mutually-agreed upon adjustments as a result of adjustments to the Closing Purchase Price pursuant to Section 2.6).  Each of Buyer and Seller shall report the transactions contemplated by this Agreement and the Ancillary Agreements for federal Income Tax and all other Tax purposes in a manner consistent with the allocation, if agreed-upon or determined by the Independent Appraiser in each case pursuant to this Section 2.7.  Each of Buyer and Seller agrees to provide the other promptly with any other information required to complete Form 8594.  Each of Buyer and Seller shall notify and provide the other with reasonable assistance in the event of an examination, audit or other proceeding regarding the agreed upon allocation of the Purchase Price.

5.5.

Interim Period Notice; Schedule Update

(a)

Each Party shall notify the other promptly if any information comes to its attention prior to the Closing that is likely to (i) excuse it from the performance of its obligations under this Agreement or any Ancillary Agreement or (ii) cause any condition to close set forth in Sections 6.1 or 6.2 not to be satisfied.

(b)

From time to time prior to the Closing Date, Seller may at its option supplement or amend and deliver updates to the Schedules (each a "Schedule Update") that are necessary to complete or correct any information in such Schedules or in any representation or warranty of Seller that has been rendered inaccurate since the Effective Date.  Without limiting Buyer’s rights under Section 10.1(b)(v), if (i) Buyer has the right to terminate the Agreement thereunder and does not exercise such right as a result of such Schedule Update (together with all other Schedule Updates delivered pursuant to this Section 5.5(b) and notices given pursuant to Section 5.5(a) and (ii) the Schedule Update pursuant to this Section 5.5(b) relates to events occurring or conditions arising after the Effective Date, then such Schedule Update shall be deemed to have amended the appropriate Schedule or Schedules as of the Effective Date, to have qualified the representations and warranties contained in Section 3 as of the Effective Date, and to have cured any misrepresentation or breach of warranty that otherwise might have existed hereunder by reason of the existence of such matter for purposes of the closing conditions set forth in Section 6.1 (but, for the avoidance of doubt, not for purposes of the indemnification obligations of Seller set forth in Article 9). Any Schedule Updates delivered pursuant to this Section 5.5(b) that relate to events occurring or conditions existing on or prior to the Effective Date shall not qualify the representations and warranties, or cure any misrepresentation or breach of warranty hereunder.

Any notices delivered pursuant to this Section 5.5(c) that relate to events occurring or conditions existing on or prior to the Effective Date shall not qualify the representations and warranties, or cure any misrepresentation or breach of warranty hereunder.

5.6.

Further Assurances.

(a)

At any time and from time to time after the Closing, at the request of a Party, the other Party will execute and deliver such instruments of sale, transfer, conveyance, assignment and confirmation and take such action as Seller and Buyer may both reasonably agree is necessary to transfer, convey and assign to Buyer, and to confirm Buyer’s title to or interest in the Acquired Assets and Assumed Liabilities or to put Buyer in actual possession and operating control of the Acquired Assets, and otherwise to consummate and give effect to the transactions contemplated pursuant to this Agreement.

(b)

In the event that any asset that is an Acquired Asset shall not have been conveyed to Buyer at the Closing, Seller shall, subject to Sections 5.6(c), (d) and (e), use its Commercially Reasonable Efforts to convey such asset to Buyer as promptly as is practicable after the Closing.

(c)

To the extent that Seller’s rights under any Contract, Lease or Power Contract may not be assigned without the consent of another Person which consent has not been obtained by the Closing Date, this Agreement shall not constitute an agreement to assign the same if an attempted assignment would constitute a breach thereof or be unlawful, and Seller and Buyer shall cooperate and shall each use their Commercially Reasonable Efforts to obtain any such required consent(s) as promptly as possible.  Seller and Buyer agree that if any consent to an assignment shall not be obtained, or if any attempted assignment would be ineffective or would impair Buyer’s rights and obligations under the Contract, Lease or Power Contract in question, so that Buyer would not in effect acquire the benefit and burden of all such rights and obligations, Seller, to the maximum extent permitted by law and such Contract, Lease or Power Contract, shall, after the Closing, appoint Buyer to be Seller’s agent with respect to such Contract, Lease or Power Contract, and Seller shall, to the maximum extent permitted by law and such Contract, Lease or Power Contract, enter into such reasonable arrangements with Buyer as are necessary to provide Buyer with the benefits and obligations of such Contract, 

Lease or Power Contract (which, in the case of the Power Contracts or the Glencore Contracts, includes but is not limited to any necessary back-to-back power purchase and/or sales arrangements).  Seller and Buyer shall cooperate and shall each use their Commercially Reasonable Efforts after the Closing to obtain an assignment of such Contract, Lease or Power Contract to Buyer.

(d)

To the extent that Seller’s rights under any warranty or guaranty described in Section 2.1(b) may not be assigned without the consent of another Person, which consent has not been obtained by the Closing Date, this Agreement shall not constitute an agreement to assign the same, if an attempted assignment would constitute a breach thereof, or be unlawful.  Seller and Buyer agree that if any consent to an assignment of any such warranty or guaranty would be ineffective or would impair Buyer’s rights and obligations under the warranty or guaranty in question, so that Buyer would not in effect acquire the benefit of all such rights and obligations, Seller shall use Commercially Reasonable Efforts, at Buyer’s sole cost and expense, to the extent permitted by law and such warranty or guaranty, to enforce such warranty or guaranty for the benefit of Buyer so as to the maximum extent possible to provide Buyer with the benefits and obligations of such warranty or guaranty.  Notwithstanding the foregoing, Seller shall not be obligated to bring or file suit against any Third Party, provided that if Seller shall determine not to bring or file suit after being requested by Buyer to do so, Seller shall assign, to the extent permitted by law or any applicable agreement or contract, its rights in respect of the claims so that Buyer may bring or file such suit.

(e)

To the extent that any personal property lease cannot be assigned to Buyer or is not subject to arrangements described in Section 5.6(c), upon Buyer’s reasonable request and at Buyer’s sole expense, Seller will use Commercially Reasonable Efforts to acquire the assets relating to such lease and to include them in the Acquired Assets before the Closing Date.

For the avoidance of doubt, Buyer shall recognize all increases in wages made in the ordinary course of business and in accordance with the Collective Bargaining Agreement between the Effective Date and the Closing Date.  Those employees who accept such offer of employment are hereinafter referred to as the "Represented Employees."  All such offers of employment shall be made in accordance with all applicable laws and regulations and the Collective Bargaining Agreement.

Within 7 days following Buyer’s delivery of such list to Seller, Buyer shall offer employment to such employees commencing as of midnight on the Closing Date for a period of at least twelve months (the "Minimum Employment Period"), at aggregate levels of wages and overall compensation substantially comparable, in the aggregate (excluding equity-based compensation and benefits under any defined benefit pension plan or post-retirement health or welfare plan), to the level of wages and overall compensation in effect for such employees as of the Effective Date; provided that Buyer shall recognize all increases in wages made in the ordinary course of business between the Effective Date and the Closing Date and provided further that during the Minimum Employment Period, Buyer shall provide to each Non-Represented Plant Employee (as defined below) a pension benefit substantially comparable to the pension benefit applicable to each such Non-Represented Plant Employee under the retirement plan of Seller or its Affiliates as of the Closing Date (and, for the avoidance of doubt, the parties acknowledge and agree that Buyer may provide such substantially comparable pension benefits pursuant to a defined contribution, rather than a defined benefit pension plan).

Period, Buyer shall provide to each Non-Represented Support Employee (as defined below) a pension benefit substantially comparable to the pension benefit applicable to each such Non-Represented Support Employee under the retirement plan of Seller or its Affiliates as of the Closing Date (and, for the avoidance of doubt, the parties acknowledge and agree that Buyer may provide such substantially comparable pension benefits pursuant to a defined contribution, rather than a defined benefit pension plan).  Those employees who accept such offer of employment are hereinafter referred to as the "Non-Represented Support Employees", and together with the Non-Represented Plant Employees and the Represented Employees are hereafter referred to as the "Acquired Assets Employees".  All such offers of employment shall be made in accordance with all applicable laws.  Notwithstanding anything herein to the contrary, all Non-Represented Support Employees will be employed as at-will employees whose employment may be terminated at any time with or without cause or reason by either the employee or Buyer; provided that if Buyer terminates any Non-Represented Support Employee during the Minimum Employment Period for any reason other than for cause, Buyer shall pay any such terminated Non-Represented Support Employee (i) an amount equal to such terminated Non-Represented Support Employee’s salary for the remainder of the Minimum Employment Period, plus (ii) Enhanced Severance; provided that such terminated Non-Represented Support Employee executes and delivers to Buyer a general release and covenant not to sue in favor of Buyer, Seller and their respective Affiliates in a form reasonably acceptable to Buyer and Seller.

(e)

Seller shall provide and remain liable for any and all continuation of coverage under the Seller Employee Benefit Plans as required under §§601 through 608 of ERISA and §4980B of the Code with respect to any person as to whom a "qualifying event" as defined in §4980 of the Code occurred on or prior to the Closing Date.

(f)

Effective as of 12:01 a.m. on the Closing Date, the Acquired Assets Employees shall cease to be employees of Seller or its Affiliates and Seller or its Affiliates shall be solely responsible for the payment of (i) all wages and compensation, (ii) except with respect to Represented Employees, severance payments and vacation pay, and (iii) other amounts thereupon legally owing to or with respect to the Acquired Assets Employees prior to 12:01 a.m. on the Closing Date, or as a result of such separation.

(i)

Notwithstanding anything to the contrary in this Section 5.7, Buyer shall have the right to use a third party operator or an Affiliate to hire Acquired Assets Employees and to perform certain actions on behalf of Buyer under this Section 5.7; provided that in no event will such use of or performance by a third party operator release Buyer from any of its obligations under this Section 5.7.

To assist Buyer in its evaluation of any and all Events of Loss, Seller shall provide Buyer such access to the Acquired Assets and such information as Buyer may reasonably request in connection therewith.

(d)

If, in the absence of a protective order or the receipt of a waiver hereunder, the Receiving Party or any Representative thereof is, on the advice of counsel, compelled to disclose any Proprietary Information pursuant to any such request or requirement, then the Receiving Party or such Representative may disclose the Proprietary Information so requested or required to be disclosed; provided that the Receiving Party shall use its reasonable best efforts to obtain, at the request of the Disclosing Party, an order or other assurance that confidential treatment will be accorded to such portion of the Proprietary Information required to be disclosed as the Disclosing Party shall designate.

None of Buyer Indemnified Parties nor Seller Indemnified Parties shall be entitled to recover from Seller or Buyer, respectively, for any Losses arising under this Agreement or in connection with or with respect to the transactions contemplated in this Agreement, any amount in excess of the actual compensatory damages, court costs and reasonable attorneys fees, suffered by such Party.  Buyer on behalf of each of Buyer Indemnified Parties and Seller on behalf of each of Seller Indemnified Parties waives any right to recover incidental, indirect, special, exemplary, punitive or consequential damages, including lost revenues or profits, even if such damages are foreseeable or the damaged Party has advised the other Party of the possibility of such damages and regardless of whether any such damages are deemed to result from the failure or inadequacy of any exclusive or other remedy. Notwithstanding the foregoing, the limitations set forth in this Section 9.5(a) with respect to indirect or consequential damages, including lost profits, shall not apply in the event of a breach by Seller of its representation in Section 3.13 (Condemnation).

(d)

Each Party entitled to indemnification hereunder or otherwise to reimbursement for Losses in connection with the transactions contemplated in this Agreement shall use Commercially Reasonable Efforts to mitigate all Losses upon becoming aware of any event or circumstance that could reasonably be expected to give rise to any Losses that are indemnifiable or recoverable hereunder or in connection herewith.

Nothing herein shall prevent either Party from terminating this Agreement in accordance with Section 10.

9.7.

Matters Involving Third Parties.

(a)

If any Third Party shall notify any Party (the "Indemnified Party") with respect to any matter (a "Third Party Claim") that may give rise to a claim for 

indemnification against any other Party (the "Indemnifying Party") under this Section 9, then the Indemnified Party shall promptly notify the Indemnifying Party thereof in writing; provided that no delay on the part of the Indemnified Party in notifying the Indemnifying Party shall relieve the Indemnifying Party from any obligation hereunder unless (and then solely to the extent) the Indemnifying Party is prejudiced thereby.

(b)

Any Indemnifying Party will have the right to defend the Indemnified Party against the Third Party Claim with counsel of its choice reasonably satisfactory to the Indemnified Party so long as (i) within fifteen (15) days after receiving such notice, the Indemnifying Party shall give written notice to the Indemnified Party stating whether it disputes the claim for indemnification and whether it will defend against any Third Party Claim or liability at its own cost and expense, (ii) the Third Party Claim involves only money damages and does not seek an injunction or other equitable relief, settlement of, or an adverse judgment with respect to, and the Third Party Claim is not, in the good faith judgment of the Indemnified Party, likely to establish a precedential custom or practice adverse to the continuing business interests of the Indemnified Party, and (iii) the Indemnifying Party conducts the defense of the Third Party Claim actively and diligently; provided that if the claim is one that cannot by its nature be defended solely by the Indemnifying Party, the Indemnified Party shall make available all information and assistance reasonably available and necessary for the defense of the Third Party Claim as the Indemnifying Party may reasonably request and shall cooperate with the Indemnifying Party in such defense.

(c)

So long as the Indemnifying Party is conducting the defense of the Third Party Claim in accordance with Section 9.7(b), (i) the Indemnified Party may retain separate co-counsel at its sole cost and expense and participate in the defense of the Third Party Claim, (ii) the Indemnified Party will not consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim without the prior written consent of the Indemnifying Party (which consent shall not unreasonably be withheld), and (iii) the Indemnifying Party will not consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim unless written agreement is obtained releasing the Indemnified Party from all liability thereunder and such judgment or settlement is not reasonably likely to have a material adverse effect on the operations of the Indemnified Party or any of its Affiliates.

(d)

In the event any of the conditions in Section 9.7(b) is or becomes unsatisfied, however, (i) the Indemnified Party may defend against, and consent to the entry of any judgment or enter into any settlement with respect to, the Third Party Claim in any manner it may deem appropriate (and the Indemnified Party need not consult with, or obtain any consent from, any Indemnifying Party in connection therewith), (ii) the Indemnifying Party will reimburse the Indemnified Party promptly and periodically for the reasonable costs of defending against the Third Party Claim (including reasonable attorneys’ fees and expenses), and (iii) the Indemnifying Party will remain responsible for any Losses the Indemnified Party may suffer resulting from, arising out of, relating to, in the nature of, or caused by the Third Party Claim to the fullest extent provided in this Section 9.

9.8.

Net of Insurance.  Any calculation of a Loss under this Section 9 shall, in each case, give full effect to any and all insurance proceeds actually received by the Indemnified Party in respect of the Loss (net of the costs of collecting such proceeds).  The Indemnified Party shall use its Commercially Reasonable Efforts to collect any insurance proceeds payable to the Indemnified Party in respect of such Loss.  If any such insurance proceeds are collected after an indemnification payment is made pursuant to this Section 9, the Indemnified Party shall pay to the Indemnifying Party the amount of such received insurance proceeds (net of the costs of collecting such proceeds), up to the amount of the indemnification payment previously made hereunder.  The Parties agree to treat any indemnity payment made pursuant to this Agreement as an adjustment to the Purchase Price, unless otherwise required by Law. Any such Loss shall not take into account, and shall not be increased to reflect, the Tax consequences to the Indemnified Party of the receipt of (or the right to receive) the indemnification payments.

9.9.

No Recourse.  To the extent the transfer, conveyance, assignment and delivery of the Acquired Assets to Buyer as provided in this Agreement is accomplished by deeds, assignments, easements, leases, licenses, bills of sale, or other instruments of transfer and conveyance, whether executed at the Closing or thereafter, these instruments are made without representation or warranty by, or recourse against, Seller or its Affiliates, except as expressly provided in this Agreement or in any such instrument.

Press Releases and Public Announcements.  No Party shall issue any press release or make any public announcement relating to the subject matter of this Agreement without first affording the non-disclosing Party the opportunity to review and comment on such press release or public announcement; provided that any Party may make any public disclosure it believes in good faith is required by applicable law or any listing or trading agreement concerning its publicly-traded securities (in which case the disclosing Party will provide the other Party with the opportunity to review in advance the disclosure).  The Parties shall cooperate, using Commercially Reasonable Efforts, as to the timing and contents of any such disclosure, including any such disclosure required by applicable law or the rules of any stock exchange.

No Third Party Beneficiaries.  This Agreement shall not confer any rights or remedies upon any Third Party.   For the avoidance of doubt, no provision of this Agreement shall create any third party beneficiary rights in any employee or former employee of any Seller or its Affiliates (including any beneficiary or dependent thereof) in respect of continued employment or resumed employment, and no provision of this Agreement shall create any rights in any such Persons in respect of any benefits that may be provided, directly or indirectly, under any employee benefit plan or arrangement.  

11.3.

No Joint Venture.  Nothing in this Agreement creates or is intended to create an association, trust, partnership, joint venture or other entity or similar legal relationship between the Parties, or impose a trust, partnership or fiduciary duty, obligation, or liability on or with respect to either Party.

This Agreement (including the Exhibits and Schedules hereto), together with the Ancillary Agreements constitute the entire agreement between the Parties and supersede any prior understandings, agreements, or representations by or between the Parties, written or oral, to the extent they relate in any way to the subject matter hereof, provided that the Confidentiality Agreement dated as of February 25, 2006 shall remain in full force and effect without regard to any provision of this Agreement until the Closing Date (except as contemplated by the definition of Proprietary Information herein), and shall terminate automatically on the Closing Date.

Succession and Assignment.  This Agreement and all of the provisions hereof shall be binding upon and inure to the benefit of the Parties and their respective successors and permitted assigns, but neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any Party, including by operation of law, without the prior written consent of the other Parties, such consent not to be unreasonably withheld or delayed.  Any assignment in contravention of the foregoing sentence shall be null and void and without legal effect on the rights and obligations of the Parties hereunder.  Notwithstanding the foregoing, but subject to all applicable Laws, (i) Buyer or its permitted assignee may assign, transfer, pledge or otherwise dispose of (absolutely or as security) its rights and interests hereunder to a trustee, lending institutions or other party for the purposes of leasing, financing or refinancing the Acquired Assets, and (ii) Buyer or its permitted assignee may assign, transfer, pledge or otherwise dispose of (absolutely or as security) its rights and interests hereunder to an Affiliate of Buyer so long as such Affiliate makes the representations and warranties set forth in Section 4 to the same extent as Buyer and provides Acceptable Guaranty to Seller; provided in each case that no such assignment shall relieve or discharge the assigning Party from any of its obligations hereunder or shall be made if it would reasonably be expected to prevent or materially impede, interfere with or delay the transactions contemplated by this Agreement or materially increase the cost of the transactions contemplated by this Agreement.  Each Party agrees, at the assigning Party’s expense, to execute and deliver such documents as may be reasonably necessary to accomplish any such assignment, transfer, pledge or other disposition of rights and interests hereunder so long as the nonassigning Party’s rights under this Agreement are not thereby materially altered, amended, diminished or otherwise impaired.  

11.6.

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

Dispute Resolution.  

(a)

Negotiation between Executives:  The Parties shall attempt in good faith to resolve any dispute arising out of or relating to this Agreement, promptly by negotiation between executives who have authority to settle the controversy.  Any Party may give the other Party written notice of any dispute not resolved in the normal course of business.  Such notice shall include: (a) a statement of that Party’s position and a summary of arguments supporting that position; and (b) the name and title of the executive who will be representing that Party and of any other person who will accompany the executive.  Within fifteen (15) days after delivery of the notice, the receiving Party shall respond with:  (a) a statement of that Party’s position and a summary of arguments supporting that position; and (b) the name and title of the executive who will represent that Party and of any other person who will accompany the 

executive.  Within thirty (30) days after delivery of the initial notice, the executives of both Parties shall meet at a mutually acceptable time and place, and thereafter as often as they reasonably deem necessary, to attempt to resolve the dispute.  All reasonable requests for information made by one Party to the other will be honored.  All negotiations pursuant to this clause are confidential and shall be treated as compromise and settlement negotiations for purposes of applicable rules of evidence.

(b)

Mediation:  If the dispute has not been resolved by negotiation within forty-five (45) days of the disputing Party’s notice, or if the Parties failed to meet within thirty (30) days, the Parties shall endeavor to settle the dispute by mediation under the then current International Institute for Conflict Prevention and Resolution ("CPR") Mediation Procedure; provided that if one Party fails to participate as provided herein, the other Party can initiate mediation prior to the expiration of the forty-five (45) days.  Unless otherwise agreed, the Parties will select a mediator from the CPR Panels of Distinguished Neutrals.

(c)

Arbitration:  Any dispute arising out of or relating to this Agreement, including the breach, termination or validity thereof, that has not been resolved by a non-binding procedure as provided herein within ninety (90) days of the initiation of such procedure, shall be finally resolved by arbitration in accordance with the then current CPR Rules for Non-Administered Arbitration by a sole arbitrator, for disputes involving amounts in the aggregate under three million dollars ($3,000,000), or three arbitrators, for disputes involving amounts in the aggregate equal to or greater than three million dollars ($3,000,000), of whom each Party shall designate one in accordance with the "screened" appointment procedure provided in Rule 5.4; provided that if either Party will not participate in a non-binding procedure, the other may initiate arbitration before expiration of the above period.  The arbitration shall be governed by the Federal Arbitration Act, 9 U.S.C. §§ 1-16, and judgment upon the award rendered by the arbitrator(s) may be entered by any court having jurisdiction thereof.  The place of arbitration shall be Hartford, Connecticut.

(d)

The arbitrator(s) are not empowered to award damages in violation of any limitations on damages provided for in this Agreement and each Party expressly waives and foregoes any right to punitive, exemplary or similar damages unless a statute requires that compensatory damages be increased in a specified manner.
