The 1998 Series A Bonds and the certificate of authentication of the Trustee upon said Bonds shall be substantially in the forms thereof respectively set forth in Schedule A appended hereto, with such changes therein as shall be approved by the Company and the Trustee. The 1998 Series A Bonds shall be designated as the First Mortgage Bonds, 1998 Series A, due June 1, 1999 of the Company, shall be issuable in the aggregate principal amount not exceeding seventeen million three hundred thousand dollars ($17,300,000) and no more except as provided in Section 2.13 of the Original Indenture. The Bonds shall be issued in fully registered form in denominations of one thousand dollars ($1,000) and any multiple thereof, and shall be redeemable in the manner provided in Section 1.05 of this Eighty-Second Supplemental Indenture. Notwithstanding the provisions of Section 2.11 of the Original Indenture, no charge, except for taxes or governmental charges, shall be made by the Company upon any registration of transfer or exchange of the 1998 Series A Bonds. 	Section 1.02. Provisions of Bonds of 1998 Series A; Interest Accrual. The bonds of 1998 Series A shall mature on June 1, 1999 and shall bear interest at the Lease Rate (as defined below), as applicable from time to time, but such interest shall accrue only upon and following the occurrence and during the continuance of an Accelerating Event (as defined below); provided, however, that in no event shall the interest rate payable on the 1998 Series A Bonds exceed 6.89% per annum; and shall be payable both as to principal and interest at the office or agency of WMECO in the Borough of Manhattan, New York, New York, in any coin or currency of the United States of America which at the time of payment is legal tender for the payment of public and private debts. After a responsible officer of the Trustee shall have received written notice from the Collateral Agent of the occurrence of an Accelerating Event, specifying in reasonable detail the events giving rise to the Accelerating Event and the date of its occurrence, interest on the outstanding 1998 Series A Bonds shall be due and payable on demand, provided, however, that upon the occurrence of an Accelerating Event which is an Insolvency Event, interest shall be immediately due and payable on demand whether or not the Trustee has received notice of the occurrence of such Accelerating Event. Interest shall accrue from and including the date of occurrence of an Accelerating Event and shall continue to accrue during the continuance of such Accelerating Event. Interest on the outstanding 1998 Series A Bonds shall cease to accrue following the discontinuance of any such Accelerating Event as evidenced by a written notice from an officer of the Collateral Agent to a responsible officer of the Trustee, and any interest on the outstanding 1998 Series A Bonds that has accrued but has not yet become due and payable at the time such notice is given shall be extinguished and shall not be required to be paid at any time thereafter. 	Except as specified in the preceding paragraph, no interest shall accrue or be payable on the 1998 Series A Bonds. 	An "Accelerating Event" shall be deemed to have occurred on any date on which the Event of Default (as defined in the Security Agreement) shall have occurred and be continuing.

The term "Lease Rate" shall mean for any day, that rate sufficient to generate interest due on the outstanding 1998 Series A Bonds for such day in an aggregate amount equal to that portion of the Daily Lease Charge (as defined in the Lease Agreement) for such day which is the obligation of WMECO under the Lease Agreement, but in no event shall such rate exceed 6.89% per annum. From time to time following the occurrence of an Accelerating Event, WMECO at the request of the Collateral Agent, shall certify to the Collateral Agent, the Trustee and the NBFT Trustee the applicable Lease Rate for each day of the period covered by such certificate. 	If any amounts due under the Credit Agreement or any IT Note Agreement (as defined in the Lease Agreement) shall become, or any bank acting as agent on behalf of the financial institutions party to the Credit Agreement or the holder or holders of any IT Notes shall so declare amounts due under such Credit Agreement or IT Note Agreement, as the case may be, to be forthwith due and payable pursuant to the terms of such Credit Agreement or IT Note Agreement, as the case may be, the entire principal of the bonds of 1998 Series A, together with interest accrued but unpaid thereon, shall without notice or demand of any kind, become immediately due and payable. 	Anything in the Indenture, this Supplemental Indenture or any bond of 1998 Series A to the contrary notwithstanding, the bonds of 1998 Series A shall be deemed paid, and all obligations of WMECO to pay at the times provided herein the principal of, premium, if any, and interest on the bonds of 1998 Series A shall be satisfied and discharged, if and to the extent, that (A) the Current Credit Agreement is terminated in its entirety and all obligations thereunder shall have been paid in full and WMECO shall not have given notice to the Trustee that such 1998 Series A Bonds shall remain outstanding, (B) each of the financial institutions party to the Credit Agreement has agreed in writing that the 1998 Series A Bonds shall be deemed paid, or (C) on June 1, 1999, no Event of Default (as defined in the Security Agreement) shall have occurred and be continuing; it being understood that the actual indebtedness evidenced by the 1998 Series A Bonds as of any time shall be limited to 19% of the Secured Obligations (as defined in the Security Agreement) as determined at such time, that at no time shall any claim be made for principal and interest on the 1998 Series A Bonds in excess of 19% of the Secured Obligations as determined at such time, and that, to the extent that the outstanding principal amount of the 1998 Series A Bonds exceeds such amount, neither the Secured Parties nor the Collateral Agent shall have any right under, or right to exercise any right granted to the holders of such excess 1998 Series A Bonds under, the Indenture. The Trustee shall be entitled to rely on written notice from the Collateral Agent that no Event of Default has occurred and is continuing under the Security Agreement.

A subsequent record date may be established by the Company by notice mailed to the owners of the bonds of 1998 Series A not less than ten (10) days preceding such record date, which record date shall not be more than five (5) days prior to the subsequent interest payment date.
