Definitions Unless otherwise indicated, certain terms that are capitalized and used throughout this Agreement are defined in Appendix A. All references herein to months are to calendar months unless otherwise expressly indicated. Recitals 1. WRC is a special purpose corporation, all of the issued and outstanding shares of which are owned by WMECO. 2. WMECO generates Receivables in the ordinary course of its business. 3. WMECO, in order to finance its business, wishes to sell Receivables to WRC, and WRC is willing, on the terms and subject to the conditions set forth herein, to purchase Receivables from WMECO. 4. WMECO and WRC each intends this transaction to be a true sale of Receivables by WMECO to WRC providing WRC with the full benefits of ownership of the Receivables, and WMECO and WRC do not intend the transactions hereunder to be, or for any purpose to be, characterized as a loan from WRC to WMECO. 5. WRC intends to sell Percentage Interests in the Receivables from time to time pursuant to the Receivables Purchase Agreement. NOW, THEREFORE, in consideration of the premises and the mutual agreements herein contained, the parties hereto agree as follows: ARTICLE I AGREEMENT TO PURCHASE AND SELL 1.1 Agreement To Purchase and Sell. On the terms and subject to the conditions set forth in this Agreement (including Article IV), WMECO agrees to sell to WRC, and WRC agrees to purchase from WMECO, from time to time on or after the Initial Closing Date, but before the Purchase and Sale Termination Date, all of WMECO's right, title and interest in and to: (a) each Receivable that was owing on the closing of WMECO's business on the day preceding the Initial Closing Date (other than Contributed Receivables); (b) each Receivable created by WMECO from and including the closing of WMECO's business on the day preceding the Initial Closing Date, to and including the Purchase and Sale Termination Date (other than Contributed Receivables); (c) all rights to, but not the obligations under, all Related Security; (d) all monies due or to become due with respect to the Receivables described in clauses (a) and (b); and (e) all proceeds (as defined in the applicable UCC) of Receivables and Related Security described in clauses (a), (b) and (c) above, including, without limitation, all Collections and other funds which either are received by WMECO, WRC or the Servicer from or on behalf of the Obligors in payment of any amounts owed in respect of the Receivables, or are applied to such amounts owed by the Obligors (including, without limitation, insurance payments that WMECO applies in the ordinary course of its business to amounts owed in respect of any Receivable). The items described in clauses (c), (d) and (e) above are collectively called the "Related Assets". All purchases hereunder shall be made without recourse, but shall be made pursuant to, and in reliance upon, the representations, warranties and covenants of WMECO set forth in this Agreement and each other Transaction Document. No obligation or liability to any Obligor on any Receivable is intended to be assumed by WRC hereunder, and any such assumption is expressly disclaimed. WRC's foregoing commitment to purchase Receivables is herein called the "Facility." 1.2 Timing of Purchases. (a) Initial Closing Date Purchases. WMECO's entire right, title and interest in (i) each Receivable that existed on the closing of WMECO's business on the day preceding the Initial Closing Date (other than Contributed Receivables), and (ii) all Related Assets with respect thereto automatically shall be deemed to be sold to WRC on the Initial Closing Date. (b) Regular Purchases. Commencing on the Initial Closing Date, until the Purchase and Sale Termination Date, each Receivable originated by WMECO (other than Contributed Receivables) and the Related Assets with respect thereto shall be sold to WRC immediately (and without further action) upon the creation of such Receivable. 1.3 Consideration for Purchases. On the terms and subject to the conditions set forth in this Agreement, WRC agrees to make WRC Purchase Price payments to WMECO in accordance with Article III. 1.4 Contributions. From time to time, upon written notice to WRC and the Agent, WMECO may elect to contribute Receivables to WRC. Any such contribution shall be effective concurrently with the origination of the Receivables to be contributed and shall include the Related Assets with respect thereto. 1.5 The "Purchase and Sale Termination Date" shall be the date of the termination of this Agreement pursuant to Section 8.1. 1.6 Servicer. WMECO shall act as the initial Servicer of the Receivables as provided herein and in the Receivables Purchase Agreement. WMECO shall perform its obligations as Servicer under the Receivables Purchase Agreement, and WRC shall pay to the Servicer the Servicing Fee. WRC may, upon notice to WMECO, with the prior written consent of the Purchaser and the Agent, designate any Person to succeed WMECO as the Servicer. Upon any such designation of any Person to succeed WMECO or any successor Servicer pursuant hereto, WMECO agrees that it will terminate its activities as the Servicer hereunder in a manner which WRC and the Agent believe will facilitate the transition of the performance of such activities to the new Servicer. Under the terms of the Receivables Purchase Agreement, WRC undertakes certain liabilities with respect to the Servicer's performance. Such undertakings shall not impair any claim WRC may have against the Servicer under the Transaction Documents for the Servicer's breach thereof. 1.7 True Sales; Security Interests. (a) WMECO and WRC intend the transfers of Receivables hereunder to be true sales by WMECO to WRC that are absolute and irrevocable and that provide WRC with the full benefits of ownership of the Receivables, and neither WMECO nor WRC intends the transactions contemplated hereunder to be, or for any purpose to be characterized as, loans from WRC to WMECO. It is, further, not the intention of the parties hereto that the conveyance of the Specified Assets be deemed a grant of a security interest in the Specified Assets by WMECO to WRC to secure a debt or other obligation of WMECO. However, in the event that, notwithstanding the intent of the parties, any Specified Assets are property of WMECO's estate, then (i) this Agreement also shall be deemed to be and hereby is a security agreement within the meaning of the UCC, and (ii) the conveyance by WMECO provided for in this Agreement shall be deemed to be a grant by WMECO to WRC of, and WMECO hereby grants to WRC, a security interest in and to all of WMECO's right, title and interest in, to and under the Specified Assets to secure (1) the rights of WRC and its assigns hereunder and (2) a loan by WRC to WMECO in the amount of the related WRC Purchase Price of such assets. WMECO and WRC shall, to the extent consistent with this Agreement, take such actions as may be necessary to ensure that, if this Agreement were deemed to create a security interest in the Specified Assets, such security interest would be deemed to be a perfected security interest of first priority in favor of WRC under applicable law and will be maintained as such throughout the term of this Agreement. It is understood and agreed that this Section 1.7(a) does not secure or guaranty the obligations of an Obligor to pay any Receivable. The immediately preceding sentence shall not limit the extent to which any other provision of this Agreement creates a claim against WMECO in respect of any Receivable (for reasons other than the Obligor's credit problems), or limit the extent to which the Specified Assets secure such claim. (b) To secure the WMECO Obligations, WMECO hereby grants to WRC, for its own benefit and the benefit of its assigns, a security interest in all right, title and interest (if any) of WMECO in the Collection Account and all items therein or attributable thereto (including without limitation all funds, interest, dividends, moneys, investments, securities and any other property received, receivable or otherwise distributed in respect of or in exchange for any or all of the foregoing). WMECO and WRC shall, to the extent consistent with this Agreement, take such actions as may be necessary to ensure that such security interest is a perfected security interest of first priority in favor of WRC under applicable law and will be maintained as such throughout the term of this Agreement. It is understood and agreed that this Section 1.7 (b) does not secure or guaranty the obligations of an Obligor to pay any Receivable. The immediately preceding sentence shall not limit the extent to which any other provision of this Agreement creates a claim against WMECO in respect of any Receivable (for reasons other than the Obligor's credit problems), or limit the extent of the collateral securing such claim. 1.8 Application of Collections. Any payment by an Obligor in respect of any indebtedness owed by it to WMECO shall, except as otherwise specified by such Obligor or otherwise required by contract or law or by instruction of the Agent, be applied as a Collection of any Receivable of such Obligor (in the order of the age of such Receivables, starting with the oldest such Receivable) to the extent of any amounts then due and payable thereunder before being applied to any other receivable or other indebtedness (other than a Receivable) of such Obligor. 1.9 Obligations of WMECO with Respect to the Receivables. WMECO will (a) at its expense, regardless of any exercise by WRC or its assigns of its rights hereunder, timely and fully perform and comply with all material provisions, covenants and other promises required to be observed by it under any contracts or other agreements related to the Receivables to the same extent as if the Receivables had not been sold hereunder and (b) pay when due any taxes (other than Excluded Taxes), including without limitation, sales and excise taxes, payable in connection with the Receivables. In no event shall WRC or its assigns have any obligation or liability with respect to any Receivables or related contracts, if applicable, nor shall any of them be obligated to perform any of the obligations of WMECO thereunder. WMECO will timely and fully comply in all material respects with the Credit and Collection Policy in regard to each Receivable and any related contract. WMECO will not make any change in the character of its business or in the Credit and Collection Policy, which change would, in either case, impair the credit quality, enforceability or collectibility of any Receivable. 1.10 Subordination. (a) The payment and performance of the Subordinated Obligations is hereby subordinated to the Senior Obligations of WRC and, except as set forth in this Section 1.10, WMECO will not ask, demand, sue for, take or receive from WRC, by setoff or in any other manner, the whole or any part of any Subordinated Obligations, unless and until such Senior Obligations shall have been fully paid and satisfied (the temporary reduction of outstanding Senior Obligations not being deemed to constitute full payment or satisfaction thereof). (b) Notwithstanding clause (a) above and subject to clause (c) below, WRC may pay the WRC Purchase Price and other Restricted Payments as provided in Section 3.1 (all such payments being herein called "Permitted Payments"). (c) Prior to payment in full by WRC of its Senior Obligations, WMECO shall have no right to sue for or otherwise exercise any remedies with respect to any Permitted Payment, or otherwise take any action against WRC or WRC's property with respect to any Permitted Payment. (d) Should any payment or distribution be received by WMECO upon or with respect to the Subordinated Obligations (other than Permitted Payments) prior to the satisfaction of all of the Senior Obligations, WMECO shall receive and hold the same in trust, as trustee, for the benefit of the holders of Senior Obligations, and shall forthwith deliver the same to the Agent (in the form received, except where endorsement or assignment by WMECO is necessary), for application to the Senior Obligations, whether or not then due. (e) In the event of any Bankruptcy Proceeding with respect to WRC, (i) WMECO shall promptly file a claim or claims, in the form required in such Bankruptcy Proceeding, for the full outstanding amount of the Subordinated Obligations, and shall use commercially reasonable efforts to cause such claim or claims to be approved and all payments or other distributions in respect thereof to be made directly to the Agent (for the benefit of the holders of Senior Obligations) until all Senior Obligations shall have been paid and performed in full and in cash, and (ii) WMECO shall not be subrogated to the rights of any such holder to receive payments or distributions from WRC until one year and one day after payment in full and in cash of all Senior Obligations. (f) If at any time any payment (in whole or in part) made with respect to any Senior Obligation is rescinded or must be restored or returned (whether in connection with any Bankruptcy Proceeding or otherwise), the subordination provisions contained in this Section 1.10 shall continue to be effective or shall be reinstated, as the case may be, as though such payment had not been made. (g) The subordination provisions contained in this Section 1.10 shall not be impaired by amendment or modification to the Transaction Documents or any lack of diligence in the enforcement, collection or protection of, or realization on, the Senior Obligations or any security therefor. ARTICLE II CALCULATION OF WRC PURCHASE PRICE 2.1 Calculation of WRC Purchase Price. (a) The purchase price (the "WRC Purchase Price") for each Receivable and its Related Assets shall equal the Outstanding Balance of such Receivable multiplied by the Discount Percentage. (b) The initial "Discount Percentage" shall equal 98.88%. The Discount Percentage shall be redetermined and set forth in the Investor Reports for each March, June, September and December. Each change in the Discount Percentage shall be effective for purchases commencing on the first day of the month following the month in which such Investor Report is delivered. The Discount Percentage shall equal the result of (i) 100% minus (ii) the sum of (x) the discount rate equivalent of a per annum interest rate equal to the sum of 1.25% plus WRC's weighted average cost of funds (excluding Contributed Receivables and other equity capital) during the preceding three Measurement Periods, plus (y) the percentage equivalent of a ratio computed by dividing (A) the aggregate Outstanding Balance of Receivables that were written off during the preceding three Measurement Periods by (B) the sum of the Collections during such three preceding Measurement Periods. ARTICLE III PAYMENT OF WRC PURCHASE PRICE 3.1 Purchase Price Payment. (a) On the Initial Closing Date, WRC shall pay WMECO the WRC Purchase Price for the Receivables and Related Assets sold on that date. Otherwise, on each Adjustment Date WRC and WMECO shall settle as to the WRC Purchase Price for Receivables and Related Assets sold during the related Measurement Period. Notwithstanding such monthly settlement arrangement, on each Business Day the Servicer will, on behalf of WRC, transfer to WMECO (for WMECO's own account except as provided in Section 3.1(b)) all Collections (other than Collections required to be used for other purposes under the Receivables Purchase Agreement) received on each Business Day and such Collections shall be applied by WMECO to any outstanding WRC Purchase Price. On each Adjustment Date, the Servicer, WRC and WMECO shall determine the aggregate amount of such transfers made during the related Measurement Period and the aggregate WRC Purchase Price for Receivables and Related Assets sold during that Measurement Period. The amounts transferred shall then be deemed to have been applied: first, as a payment of deferred WRC Purchase Price for Receivables sold during any earlier Measurement Period and their Related Assets; and second, as a payment of the aggregate WRC Purchase Price for Receivables sold during the related Measurement Period and their Related Assets. (b) Any portion of the WRC Purchase Price for Receivables and Related Assets sold during any Measurement Period which is not paid pursuant to priority second above shall be treated as deferred WRC Purchase Price and shall be payable from time to time as provided in subsection (a); provided that any unpaid deferred WRC Purchase Price shall be due and payable on the date that falls nine months after the Purchase and Sale Termination Date. If it is determined on any Adjustment Date that Collections paid by the Servicer to WMECO pursuant to Section 3.1(a) during the related Measurement Period exceeded the sum of (i) the WRC Purchase Price payable for such Measurement Period plus (ii) amounts owed by WRC at the start of such Measurement Period for WRC Purchase Price accrued during previous Measurement Periods, WMECO shall remit such excess to WRC in immediately available funds on the next succeeding Business Day following WRC's request therefor. WRC may also elect to declare a dividend (in an amount up to such excess) to WMECO, subject to such restrictions as are set forth in Section 5.01(k) of the Receivables Purchase Agreement. (c) The Servicer (based on information provided to it by WRC) shall at all times maintain information sufficient to determine the net amount owed by WRC to WMECO, or by WMECO to WRC, in respect of such WRC Purchase Price; provided, that nothing in this Section 3.1 shall be construed to require the Servicer or any Affiliate thereof to deliver to WMECO, WRC or the Agent, a report setting forth any calculation under this Section 3.1, except (i) for the delivery of an Investor Report in accordance with Section 6.07 of the Receivables Purchase Agreement and (ii) to the extent requested by WRC or the Agent (x) at any time after the occurrence and during the continuance of a Servicer Default or a Transition Event, or (y) on the Termination Date. 3.2 Settlement as to Specific Receivables and Dilution. (a) If on the day of any purchase or contribution of Receivables from WMECO hereunder, any of the representations or warranties relating to title set forth in Section 5.1(h) is not true with respect to such Receivable, then subject to subsection (c) below, the WRC Purchase Price that otherwise would be paid to WMECO with respect to Receivables subsequently generated by WMECO shall be decreased by an amount equal to the Outstanding Balance of such Receivable; provided, that if WRC thereafter receives payment on account of Collections due with respect to such Receivable, WRC promptly shall deliver such funds to WMECO. (b) If, on any day, the Outstanding Balance of any Receivable purchased or contributed hereunder is reduced or adjusted on account of any defective, rejected, returned, repossessed or foreclosed merchandise, any defective, disputed or rejected services, any discount or any other adjustment made or performed by WMECO or any other Person (including, without limitation, those described in the definition of "Dilution Factors") or as a result of a setoff in respect of any claim by the Obligor thereof against WMECO or any of its Affiliates (whether such claim arises out of the same or a related transaction or an unrelated transaction) as indicated on the books of WRC (or, for periods prior to the Initial Closing Date, the books of WMECO), then, subject to subsection (c) below, the WRC Purchase Price that otherwise would be paid to WMECO with respect to Receivables subsequently generated by WMECO shall be decreased by the amount of such net reduction. (c) If any decrease is required in the WRC Purchase Price of subsequently generated Receivables pursuant to subsection (a) or (b) above at any time (i) when an Event of Termination (or an event or condition that would constitute an Event of Termination but for the requirement that notice be given or time elapse or both) exists or (ii) on or after the Purchase and Sale Termination Date, then, in lieu of such reduction, the amount by which the WRC Purchase Price should have been so reduced shall be deposited by WMECO in same day funds into the Collection Account for application by the Servicer to the same extent as if Collections of the applicable Receivable in such amount had actually been received on such date. (d) Each Investor Report (other than the Investor Report delivered on the Initial Closing Date) shall include, in respect of the Receivables previously generated by WMECO (including the Contributed Receivables), a calculation of the aggregate reductions described in subsection (a) or (b) of this Section 3.2 relating to such Receivables since the last Investor Report delivered hereunder. ARTICLE IV CONDITIONS OF PURCHASES AND SALES 4.1 Conditions Precedent to Initial Purchase.

In order to induce WRC to enter into this Agreement and to make purchases hereunder, WMECO hereby makes the representations and warranties set forth in this Article V: (a) WMECO is a corporation duly incorporated, validly existing and in good standing under the laws of Massachusetts and is duly qualified to do business, and is in good standing, in every other jurisdiction in which the failure to be so qualified could reasonably be expected to have a Material Adverse Effect. (b) The execution, delivery and performance by WMECO of this Agreement and all other Transaction Documents, including WMECO's use of the proceeds of sales hereunder and reinvestments, are within WMECO's corporate powers, have been duly authorized by all necessary corporate action, do not contravene (i) WMECO's charter or by-laws, (ii) any law, rule or regulation applicable to WMECO, (iii) any contractual restriction binding on or affecting WMECO or its property or (iv) any order, writ, judgment, award, injunction or decree binding on or affecting WMECO or its property, and do not result in or require the creation of any lien, security interest or other charge or encumbrance upon or with respect to any of its properties (other than in favor of WRC or the Purchaser with respect to the Receivables and the Related Security and Collections associated therewith); and no transaction contemplated hereby requires compliance with any bulk sales act or similar law. This Agreement has been duly executed and delivered by WMECO. (c) No authorization or approval or other action by, and no notice to or filing with, any governmental authority or regulatory body is required for the due execution, delivery and performance by WMECO of this Agreement or any other Transaction Document or instrument to be delivered hereunder, except for such filings as have been made and such approvals as have been obtained and except for the filing of the UCC financing statements referred to in Article IV. (d) This Agreement and each other Transaction Document or instrument delivered by it hereunder constitutes the legal, valid and binding obligation of WMECO enforceable against WMECO in accordance with its terms. (e) The consolidated balance sheets of each of the Parent and WMECO as at December 31, 1996, and the related statements of income, shareholders' equity and cash flows for the fiscal year then ended, copies of which have been furnished to the Agent, fairly present the consolidated financial condition of the Parent and WMECO and their consolidated subsidiaries as at such date and the consolidated results of the operations of the Parent, WMECO and their consolidated subsidiaries for the period ended on such date, all in accordance with GAAP. Since December 31, 1996, except as disclosed in the Public Disclosure Documents, there has been no change in any such condition or operations which has had, or could reasonably be expected to have, a Material Adverse Effect. Since December 31, 1996, except as disclosed in the Public Disclosure Documents, there has been no change in any such condition or operations that has had, or reasonably could be expected to have, a material adverse effect on the operations or financial condition of the Parent. (f) Except as disclosed in the Public Disclosure Documents, (i) there is no pending or threatened action or proceeding affecting the Parent, WMECO or any of their subsidiaries before any court, governmental agency or arbitrator that has had, or reasonably could be expected to have, a Material Adverse Effect, (ii) none of the Parent, WMECO or any of their subsidiaries is in default with respect to any order of any court, arbitrator or governmental body except defaults, if any, which are not material (and cannot reasonably be expected to become material) to the business or operations of WMECO or any of its subsidiaries and which have not had (and cannot reasonably be expected to have) a Material Adverse Effect, and (iii) no other condition exists that has caused, or could reasonably be expected to cause, a Material Adverse Effect. Except as disclosed in the Public Disclosure Documents, (i) there is no pending or threatened action or proceeding affecting the Parent or any of its subsidiaries before any court, governmental agency or arbitrator that has had, or could reasonably be expected to have, a Material Parent Effect, and (ii) neither the Parent nor any of its subsidiaries is in default with respect to any order of any court, arbitrator or governmental body. (g) No proceeds of any sale of Receivables hereunder will be used by WMECO to acquire any security in any transaction which is subject to Section 13 or 14 of the Securities Exchange Act of 1934, as amended. (h) Each Receivable, together with any contract related thereto, and the Specified Assets shall, at all times prior to its sale or contribution hereunder, be owned by WMECO free and clear of any Adverse Claim except as created by this Agreement, and upon each purchase or contribution hereunder, WRC shall acquire valid and perfected first priority ownership of each Receivable then being sold or contributed and in the Related Security (other than Security Deposits) and Collections with respect thereto, free and clear of any Adverse Claim except as provided hereunder and in the Receivables Purchase Agreement. No Adverse Claim arising against or through WMECO shall at any time attach, or be purported to attach, to Receivables transferred to WRC or Related Security or Collections with respect thereto. No effective financing statement or other instrument similar in effect covering any Receivable, the Related Security, the Collections or the Specified Assets with respect thereto shall at any time be on file in any recording office except such as may be filed in favor of WRC or the Purchaser. (i) No Investor Report, information, exhibit, financial statement, document, book, record or report furnished or to be furnished by WMECO to the Agent or WRC in connection with this Agreement or the Receivables Purchase Agreement is or will be inaccurate in any material respect as of the date it is or shall be dated or (except as otherwise disclosed to the Agent or WRC, as the case may be, at such time) as of the date so furnished, and no such document contains or will contain any material misstatement of fact or omits or shall omit to state a material fact or any fact necessary to make the statements contained therein not misleading. Any Receivable described as an Eligible Receivable in any Investor Report or such other information, exhibit, financial statement, document, book, record or report satisfies the requirements of the definition of "Eligible Receivable" in the Receivables Purchase Agreement. WMECO has management information systems that are adequate to generate reliable statistical information with respect to the Receivables, including such information as is required to be delivered pursuant to the terms of this Agreement. (j) The principal place of business and chief executive office of WMECO and the offices where WMECO keeps all of the Records are located at the addresses specified in Exhibit B (or at such other locations as to which the notice and other requirements specified in Section 7.3 shall have been satisfied). WMECO has places of business in more than one town in Massachusetts. (k) All Obligors have been (or, in the case of Obligors with respect to Unbilled Receivables, will be) instructed to make all payments in respect of Receivables to WMECO's post office box in Hartford, Connecticut or to a Payment Center, and such payments are (i) processed by the Servicer in Wethersfield, Connecticut and (ii) deposited to the Collection Account within one Business Day of the Servicer's receipt thereof. WMECO will make commercially reasonable efforts to prevent funds other than Collections from being deposited to the Collection Account. (l) All Obligors (other than Obligors in respect of Unbilled Receivables) are listed on the General Trial Balance. WMECO's methodology for determining the Outstanding Balance of Unbilled Receivables is accurately described in Exhibit B of the Receivables Purchase Agreement and such description does not omit any fact necessary to make the statements contained therein not misleading. The Outstanding Balance of Unbilled Receivables shall be calculated in accordance with the methodology described in Exhibit B of the Receivables Purchase Agreement. (m) Except as described in Exhibit C, WMECO has no trade names, fictitious names, assumed names or "doing business as" names other than those names with respect to which it has satisfied its obligations under Section 7.3. (n) On the date of each purchase hereunder (both before and after giving effect to the purchase on such date), WMECO will have assets which are greater than the amount of its liabilities, and will be able to pay its debts as they become due. (o) The terms of the Receivables have not been extended or modified, except as permitted under the Credit and Collection Policy. (p) The Credit and Collection Policy has not been materially changed in any way which might reasonably lead to a Material Adverse Effect. (q) No sale or contribution of any Receivables or any Related Security to WRC by WMECO has been made on account of an antecedent debt owed by WMECO to WRC or constitutes a fraudulent transfer or fraudulent conveyance or is otherwise void or voidable under similar laws or principles, the doctrine of equitable subordination or for any other reason. The transfers of Receivables and Related Security by WMECO to WRC pursuant to this Agreement, and all other transactions between WMECO and WRC, have been and will be made in good faith and without intent to hinder, delay or defraud creditors of WMECO, and WMECO acknowledges that it has received and will receive reasonably equivalent value for the purchases by (and contributions to) WRC of Receivables and Related Security hereunder. The purchase and contribution of Receivables and Related Security by WRC from WMECO constitutes a true sale or contribution of such Receivables and Related Security under applicable state law. (r) No use of any proceeds of any sale of Specified Assets by WMECO will conflict with or contravene any of Regulations G, T, U and X promulgated by the Board of Governors of the Federal Reserve System. ARTICLE VI COVENANTS OF WMECO 6.1 General Covenants. WMECO covenants as follows: (a) Compliance with Laws; Preservation of Corporate Existence. WMECO will comply in all material respects with all applicable laws, and all governmental rules, regulations and orders and preserve and maintain its corporate existence, rights, franchises, qualifications and privileges, in each case to the extent that the failure to do so could reasonably be expected to cause a Material Adverse Effect.

WMECO will not merge or consolidate with, or convey, transfer, lease or otherwise dispose of (whether in one transaction or in a series of transactions), all or substantially all of its assets (whether now owned or hereafter acquired), or acquire all or substantially all of the assets or capital stock or other ownership interest of any Person (any such transaction, acquisition or other action hereinafter referred to as a "Reorganization"), except that WMECO may enter into a Reorganization if the following conditions are satisfied: (i) the survivor (such term referring to the survivor of a merger or consolidation as well as the acquirer of assets, capital stock or other ownership interests) of such Reorganization is organized under the laws of, and is resident in, the United States or one of the states therein; (ii) the senior secured debt of such survivor shall be rated at least BBB- by Standard & Poor's and Baa3 by Moody's; (iii) if WMECO is not the survivor of the Reorganization, such survivor shall have assumed all of the obligations of WMECO under or in connection with the Transaction Documents pursuant to an agreement in form and substance satisfactory to the Agent; (iv) if WMECO is not the survivor of the Reorganization, the Agent shall have received opinions of counsel satisfactory to the Agent with respect to the matters covered by the opinions delivered pursuant to Section 4.1(g) and (h), and any modifications or additions to Uniform Commercial Code filings or other security arrangements requested by the Agent shall have been completed; and (v) each of Standard & Poor's and Moody's shall have confirmed that such merger or consolidation will not cause the ratings of the Purchaser's commercial paper notes to be reduced or withdrawn.

(g) Marking of Records. At its expense, WMECO will mark (or cause the Servicer to mark) its master data processing records relating to the Receivables so that reports generated from such records include the following legend: "THE RECEIVABLES DESCRIBED HEREIN HAVE BEEN SOLD TO WMECO RECEIVABLES CORPORATION PURSUANT TO A PURCHASE AND SALE AGREEMENT, DATED AS OF MAY 22, 1997, AS AMENDED OR SUPPLEMENTED FROM TIME TO TIME, BETWEEN WESTERN MASSACHUSETTS ELECTRIC COMPANY AND WMECO RECEIVABLES CORPORATION; AND UNDIVIDED, FRACTIONAL OWNERSHIP INTERESTS IN THE RECEIVABLES DESCRIBED HEREIN HAVE BEEN SOLD BY WMECO RECEIVABLES CORPORATION TO MONTE ROSA CAPITAL CORPORATION PURSUANT TO A RECEIVABLES PURCHASE AGREEMENT, DATED AS OF MAY 22, 1997, AS AMENDED OR SUPPLEMENTED FROM TIME TO TIME, AMONG WMECO RECEIVABLES CORPORATION, WESTERN MASSACHUSETTS ELECTRIC COMPANY, MONTE ROSA CAPITAL CORPORATION AND UNION BANK OF SWITZERLAND, NEW YORK BRANCH, AS THE AGENT"; (h) Payment Instructions.

(iii) WMECO will not take any action to cause or permit any Receivable generated by it to become evidenced by any "instrument" or "chattel paper" (as defined in the applicable UCC) unless such "instrument" or "chattel paper" shall be delivered to WRC (which in turn shall deliver the same to the Purchaser (or the Agent on its behalf)).

ARTICLE VII ADDITIONAL RIGHTS AND OBLIGATIONS IN RESPECT OF THE RECEIVABLES 7.1 Rights of WRC. WMECO hereby authorizes WRC, the Servicer or their respective successors, assigns or designees to take any and all steps in WMECO's name necessary or desirable, in their respective determination, to collect all amounts due under any and all Receivables, including, without limitation, endorsing the name of WMECO on checks and other instruments representing Collections and enforcing such Receivables and the provisions of any related contracts that concern payment and/or enforcement of rights to payment. 7.2 Responsibilities of WMECO. Anything herein to the contrary notwithstanding: (a) If requested by WRC or the Agent to do so following the occurrence of a Transition Event, WMECO shall direct, all Obligors to make payments of Receivables directly to a Lock-Box Account (or to wire payments of Receivables directly to a Lock-Box Account) at a Lock-Box Bank, and WMECO shall deliver to such Lock-Box Bank a Bank Notice. WMECO shall, upon the request of the Agent at any time after a Transition Event and at WMECO's expense, notify any or all of the Obligors of the Owners' interests therein. If WMECO shall fail to give any such direction or notice promptly following the direction of WRC or the Agent, WRC or the Agent may (but shall not be required to) itself give such notice, and the expenses of WRC or the Agent incurred in connection therewith shall be payable by WMECO or the Agent on demand therefor by WRC or the Agent. (b) WMECO shall use commercially reasonable efforts to prevent funds other than Collections in the Collection Account. In the event WMECO is aware that any other amount is so deposited in the Collection Account, WMECO shall promptly notify WRC, the Agent and the Servicer. If the Servicer receives such notice at a time when a WMECO Obligation is in default, the Servicer shall deliver such amount to the Agent to pay such WMECO Obligation and to otherwise secure payment of the WMECO Obligations. The Agent shall hold such amount until all WMECO Obligations (whether fixed or contingent) are paid in full. If the Servicer receives such notice at a time when no WMECO Obligation is in default, the Servicer shall promptly remit such amount to WMECO. (c) WMECO agrees to transfer directly to the Collection Account, within one Business Day of receipt thereof, any Collections or any other payment with respect to the Receivables or Related Security that it receives, in the form so received, and agrees that all such Collections and payments shall be deemed to be received in trust for WRC and its assigns (including the Purchaser and the Agent) and such Collections shall be maintained and segregated separate and apart from all other funds and moneys of WMECO until delivery of such Collections and payments to the Collection Account for allocation in accordance with Article II of the Receivables Purchase Agreement; (d) WMECO shall perform its obligations hereunder, and the exercise by WRC or its designee of its rights hereunder shall not relieve WMECO from such obligations. (e) Neither WRC, the Servicer, the Purchaser nor the Agent shall have any obligation or liability to any Obligor or any other third Person with respect to any Receivables, contracts related thereto or any other related agreements, nor shall WRC, the Servicer, the Purchaser or the Agent be obligated to perform any of the obligations of WMECO thereunder. (f) WMECO hereby grants to the Servicer an irrevocable power of attorney, with full power of substitution, coupled with an interest, to take in the name of WMECO all steps necessary or advisable to endorse, negotiate or otherwise realize on any document or other right of any kind held or transmitted by WMECO or transmitted or received by WRC (whether or not from WMECO) in connection with any Receivable. WMECO shall execute and deliver such additional documents as WRC or the Agent shall reasonably request to evidence the power of attorney created by this Section. 7.3 UCC Matters; Protection and Perfection of Percentage Interests. WMECO will keep its principal place of business and chief executive office, and the office where it keeps the Records, at the addresses of the Seller specified in Exhibit B or, upon 30 days' prior written notice to the Agent, at such other locations within the United States where all actions reasonably requested by the Agent to protect and perfect the interest of WRC, the Agent and the Owners in the Receivables, the Related Security (excluding Security Deposits) relating thereto, the Collections and the Specified Assets, have been taken and completed. WMECO will not make any change to its corporate name or use any tradenames, fictitious names, assumed names or "doing business as" names other than those described in Exhibit C, unless prior to the effective date of any such name change or use, WMECO delivers to the Agent such executed financing statements as the Agent may request to reflect such name change or use, together with such other documents and instruments as the Agent may reasonably request in connection therewith. WMECO agrees that from time to time, at its expense, it will promptly execute and deliver all further instruments and documents, and take all further action that WRC or the Agent may reasonably request in order to perfect, protect or more fully evidence the interests of WRC, the Agent or the Owners in the Specified Assets, or to enable any of them to exercise or enforce any of their respective rights hereunder or under any other Transaction Document. Without limiting the generality of the foregoing, WMECO will upon the request of WRC or the Agent execute and file such financing or continuation statements, or amendments thereto or assignments thereof, and such other instruments or notices, as may be necessary or appropriate or as WRC or the Agent may request. WMECO hereby authorizes WRC or the Purchaser to file one or more financing or continuation statements, and amendments thereto and assignments thereof, relative to all or any of the Specified Assets now existing or hereafter arising without the signature of WMECO where permitted by law. A carbon, photographic or other reproduction of this Agreement or any financing statement covering the Specified Assets (or, in each case, any part thereof) shall be sufficient as a financing statement where permitted by applicable law. If WMECO fails to perform any of its agreements or obligations under this Section 7.3, WRC or the Agent may (but shall not be required to) itself perform, or cause performance of, such agreement or obligation, and the expenses of WRC or the Agent incurred in connection therewith shall be payable by WMECO upon demand by WRC or the Agent therefor. For purposes of enabling WRC and the Agent to exercise their rights described in the preceding sentence and elsewhere in this Agreement, WMECO hereby authorizes WRC and the Agent to take any and all steps in WMECO's name and on behalf of WMECO necessary or desirable, in the determination of WRC or the Agent, to collect all amounts due under any and all Receivables, including, without limitation, endorsing WMECO's name on checks and other instruments representing Collections and enforcing rights with respect to Receivables and any related contracts. In addition, to the extent that any Receivables are likely to be outstanding five years or more after the date of this Agreement, WMECO shall provide, within six months (but not later than the 30th day) prior to the expiration of such five year period (and, if applicable, each subsequent five year period), or more frequently as WRC or the Agent reasonably deems advisable, an opinion of counsel to WMECO as to the continuing validity and perfection of interests of WRC, the Agent and the Owners in the Specified Assets. ARTICLE VIII PURCHASE AND SALE TERMINATION 8.1 Termination. (a) Optional Termination. Upon at least 10 days' prior written notice to the other party hereto and the Agent, WMECO or WRC may declare the Purchase and Sale Termination Date to have occurred; provided that WMECO shall have paid to the Agent (for WRC's account) all obligations incurred by WRC under Section 2.11 of the Receivables Purchase Agreement in connection with, or as a direct or indirect consequence of, such declaration. (b) Upon the occurrence of the Termination Date under the Receivables Purchase Agreement, the Purchase and Sale Termination Date shall be deemed to have occurred, without further action by any Person; provided that (unless an Event of Termination under Section 7.01(g) of the Receivables Purchase Agreement shall have occurred) the parties hereto may elect, by written notice to the Agent, to continue to sell Receivables hereunder following the occurrence of an Event of Termination. (c) If the Trigger Conditions exist for a period of more than five consecutive Business Days, the Purchase and Sale Termination Date shall be deemed to have occurred, without further action by any Person. The "Trigger Conditions" shall exist on any day if, after giving effect to any increase in (or payments on) the outstanding amount of the deferred WRC Purchase Price on such day, the sum of (x) the remaining unpaid balance of the deferred WRC Purchase Price plus (y) the aggregate Purchase Price of all Percentage Interests would exceed 91% of the aggregate Outstanding Balance of all Receivables. 8.2 Remedies. Upon any termination of the Facility pursuant to Section 8.1, WRC shall have, in addition to all other rights and remedies under this Agreement or otherwise, all other rights and remedies provided under the UCC of each applicable jurisdiction and other applicable laws, which rights shall be cumulative. Without limiting the foregoing, the occurrence of the Purchase and Sale Termination Date shall not deny WRC any remedy in addition to termination of the Facility to which WRC may be otherwise appropriately entitled, whether at law or equity. ARTICLE IX INDEMNIFICATION 9.1 Indemnities by WMECO. Without limiting any other rights which WRC may have hereunder or under applicable law, WMECO hereby agrees to indemnify WRC and each of its officers, directors, employees and agents and their respective successors, transferees and assigns (each of the foregoing Persons being individually called a "Purchase and Sale Indemnified Party"), forthwith on demand, from and against any and all damages, losses, claims, judgments, liabilities and related costs and expenses, including reasonable attorneys' fees and disbursements (all of the foregoing being collectively called "Purchase and Sale Indemnified Amounts") awarded against or incurred by any of them arising out of or as a result of this Agreement, any other Transaction Document, the ownership or funding of any Receivable or other asset described in Section 1.1, or arising out of the claims asserted against a Purchase and Sale Indemnified Party relating to the transactions contemplated herein or therein or the use of proceeds herefrom or therefrom, excluding, however, (i) Purchase and Sale Indemnified Amounts to the extent resulting from gross negligence or willful misconduct on the part of any Purchase and Sale Indemnified Party, (ii) recourse (except as otherwise specifically provided in this Agreement) for uncollectible Receivables, or (iii) Excluded Taxes.

Section 101 et seq.), as amended; (q) any claim involving environmental liability that relates to any property that has been, is now or hereafter will be owned, leased, operated or otherwise used by WMECO; and (r) any violation of any provision of ERISA, the engaging by WMECO or any ERISA Affiliate in any prohibited transaction for which WMECO or such affiliate may be liable for excise taxes under the Code or otherwise liable under ERISA and for which an exemption is not available or has not been previously obtained from the United States Department of Labor, the existence of any accumulated funding deficiency, as defined in Section 302(a) of ERISA and Section 412(a) of the Code, with respect to any Benefit Plan other than a Multiemployer Plan; the failure by WMECO or any ERISA Affiliate to make a payment to any Multiemployer Plan that WMECO or any ERISA Affiliate is required to make or any other contribution failure with respect to any Benefit Plan sufficient to give rise to a lien under Section 302(f) of ERISA, the termination by WMECO or any ERISA Affiliate of any Benefit Plan or the withdrawal by WMECO or any ERISA Affiliate from any Multiemployer Plan; any attempt by the Pension Benefit Guaranty Corporation to terminate any Benefit Plan.
