All of the above amounts are to be determined as at the Participant's Termination of Employment. 2. Form of Payment --------------- Retirement Income shall be payable in the normal form as follows: (a) If a Participant has a Spouse, the normal form of payment shall be a contingent annuitant option with the Spouse, as contingent annuitant, entitled to receive 50% of the Participant's reduced amount of Retirement Income. (b) If a Participant does not have a Spouse, the normal form of payment shall be a straight life annuity with no amount of Retirement Income payable after the Former Participant's death. If a Participant elects an optional form of payment under the Qualified Plan, the same option and actuarial equivalent factors shall apply to Retirement Income payable under the Supplemental Plan; provided, however, to the extent the form of benefit was dictated by the terms of a qualified domestic relations order, the form may be that which would have applied (or any form that could have been elected) in the absence of said order. In calculating the benefit payable under any option, the same actuarial equivalent factors in the Qualified Plan shall be used in the Supplemental Plan except that no reduction factors for retirement prior to age 65 shall be applied against a Participant's Retirement Income. 3. Spouse's Death Benefit ---------------------- The Spouse of a Participant vested under the Qualified Plan who has not had a Termination of Employment is entitled to a pre-retirement spouse benefit, if the Participant dies before payment of benefits commence. The Spouse will be entitled to receive an annual benefit determined as follows: (a) as if the Participant had retired and elected Retirement Income payments to begin on the first day of the month next following the later of the date of death or Participant's fifty-fifth birthday, and (b) the Retirement Income was payable in the form of a contingent annuitant option with the Spouse, as contingent annuitant, entitled to receive 50% of the Participant's amount of Retirement Income subject to reduction for benefits payable hereunder under a domestic relations order. Timing of Payments - ----------------- A Participant shall be eligible for benefits under the Supplemental Plan when and if he is eligible for benefits under the Qualified Plan, except as provided herein. Benefits shall commence on the date on which the Participant or the Spouse first receives benefits under the Qualified Plan. Lump Sum Payments - ----------------- Any provision of the Supplemental Plan to the contrary notwithstanding, if (i) any company shall fail to make any payment to any Participant when due under the Supplemental Plan or (ii) the employer or company shall fail to make any payment to any participant due under any of the New England Electric Companies' Incentive Compensation Plan, the New England Electric Companies Deferred Compensation Plan, or the New England Electric System Companies Retirement Supplement Plan, the full amount of the current Actuarial Value of his benefits under the Supplemental Plan shall be payable immediately to each Participant as a lump-sum; provided, however, if any employer or company shall, in good faith, contest a claim by a participant under this Supplemental Plan or any of the other above-listed plans, the failure to make the contested payment or payments shall not, for the purpose of this paragraph, be a failure to make a payment. At any time following a Change in Control or Major Transaction, any Participant who has had a Termination of Employment, whether before or after the Change in Control or Major Transaction, may elect to receive, in lieu of any future benefits hereunder, a lump sum payment equal to the Actuarial Value of the maximum value of said future benefits, less 10%. If the Company does not make the aforesaid lump sum payments, the New England Electric System will make the payment for the account of the Company. Vesting and Forfeiture of Benefits - ---------------------------------- Except as provided in the following paragraph, a Participant's accrued benefit shall be 100% vested after five Years of Service. A Participant will forfeit his benefits under the Supplemental Plan if before the earlier of age 65 or five years following termination of employment he, without the prior consent of the New England Electric System's Chief Executive Officer (the "CEO"), enters into or in any manner takes part in, as an employee, agent, officer, owner, or otherwise, any business or authority which in the opinion of the CEO is in competition with, in the same field as, or regulating the business of New England Electric System or any of its subsidiaries, or which in the opinion of the CEO provides services peculiarly essential to utility operation. Violation of this provision will result in termination of payments, and any obligations to make future payments to the Participant and the Participant's Spouse. A Participant may request to have the Committee review any decision made by the CEO under this provision that adversely affects the Participant. The Committee's decision shall be final. Upon the occurrence of a Change in Control or a Major Transaction, the second paragraph of this section shall no longer have any effect. Administration and Claims - ------------------------- The Administrator shall have for the Supplemental Plan the same duties as for the Qualified Plan, except as specifically provided herein. The Benefits Appeal Committee for the Qualified Plan shall have for the Supplemental Plan the same duties relative to denied claims as for the Qualified Plan, except as may be specifically provided herein. Government Regulations - ---------------------- It is intended that the Supplemental Plan will comply with all applicable laws and governmental regulations, and the Company shall not be obligated to perform an obligation hereunder in any case where, in the opinion of the Company's counsel, such performance would result in violation of any law or regulation. Nonassignment - ------------- To the fullest extent permitted by law, no benefit under the Plan, nor any other interest hereunder of any Participant, Spouse, or contingent annuitant, shall be assignable, transferable, or subject to sale, mortgage, pledge, hypothecation, commutation, anticipation, garnishment, attachment, execution, or levy of any kind. Provisions of Benefits - ---------------------- The Supplemental Plan will be unfunded. Benefits will be paid from the operating revenues of the Company. A Participant's rights to benefits under the Supplemental Plan shall be those of an unsecured, general creditor of the Company. Amendment or Discontinuance - --------------------------- The Committee may amend or discontinue the Supplemental Plan at any time; provided, no modification shall reduce a benefit which a Participant was eligible to receive under the Supplemental Plan at the time of such amendment or discontinuance; and provided further, no amendment or discontinuance in any manner adverse to a Participant with respect to benefit formula or optional form of payment may be made for three years following a Change in Control or a Major Transaction. Effective Date - -------------- The Plan, as amended, is to be effective for retirements on and after January 1, 1995. s/ George M. Sage Chairman of the Compensation Committee Pursuant to Votes of August 24, 1993, November 22, 1994, and February 27, 1995
