Section 11 is amended by adding the following sentence at the end thereof: "The provisions of this Section 11 shall not apply in the case of an Eligible Officer receiving benefits pursuant to Section 5(c)." 17. The second subparagraph of Section 12 (begins: "Notwithstanding the foregoing ...") is amended to read as follows: "Notwithstanding the foregoing, Eastern in its sole discretion may establish a so-called "rabbi" trust or similar trust, whether or not conforming to Rev. Proc. 92-64, or may avail itself of any such trust which it has previously established, to provide for the payment of benefits hereunder, subject to such terms as the Board of Trustees may determine (a "trust"). In the event Eastern established a trust in respect of the Plan or causes a pre-existing trust to cover the Plan, and at the time of a Change of Control such trust (i) has not been terminated or revoked and (ii) is not "fully funded" (as hereinafter defined), Eastern shall promptly deposit in such trust cash sufficient to cause the trust to be "fully funded" as of the date of the deposit. For purposes of this subparagraph, any such trust shall be deemed "fully funded" as of any date if, as of that date, the fair market value of the assets held in trust is not less than (1) the aggregate present value as of that date of all benefits then in pay status under the Plan (including benefits not yet commenced but in respect of Eligible Officers whose employment has terminated in accordance with Section 5(e)(i), (ii), (iii) or (iv)) plus (2) the aggregate present value as of that date of all benefits that would be payable under the Plan if all other persons who are (or, but for not yet having attained age 55, would be) Eligible OfficErs were deemed to have terminated employment on that date in accordance with Section 5(e)(i), (ii), (iii) or (iv) plus (3) the aggregate present value as of that date of all benefits payable (as determined under rules similar to the rules described in (1) and (2)) under all other defined-benefit type plans and arrangements provided for through the trust, plus (4) the aggregate of the account balances, determined as of such date, under all individual-account type plans and arrangements provided for through the trust. In applying clauses (1), (2) and (3) of the previous sentence, present value shall be determined by using the interest and mortality assumptions used in determining lump sum present values under the qualified defined benefit pension plan maintained by Eastern, of if no such qualified plan is then maintained by Eastern, by applying the assumptions used prior to the Change of Control in determining Eastern's pension expense under FAS 87 or any successor pronouncement with respect to such plan or arrangement." 18. Section 14 is amended to provide as follows: "Termination: Amendment: Other. Eastern reserves the right at any time by action of its Board of Trustees to terminate the Plan or to amend its provisions in any way, except that following the date which precedes by six months a Change of Control no such amendment or termination shall reduce the amount of Eastern's obligations under Section 12 or extend the period within which Eastern may satisfy such obligations. In addition, the Plan will automatically terminate if at any time (and as of the date that) the Retirement Plan is terminated. Notwithstanding the foregoing, no termination or amendment of the Plan (a "Plan Change") will reduce the benefit payable under the Plan to any person with respect to an Eligible Officer whose employment with Eastern and its subsidiaries was terminated prior to such Plan Change, nor shall any Plan Change reduce the benefit, if any, to be paid with respect to a person who is (or, but for not yet having attained age 55, would be) an Eligible Officer on the date of such Plan Change below the amount which such person would have received if his employment had terminated in accordance with Section 5(e)(i), (ii), (iii) or (iv) on the day before such Plan Change; provided, however, that benefits otherwise payable hereunder with respect to an individual may be reduced or otherwise modified by separate agreement between Eastern and such individual." IN WITNESS WHEREOF, Eastern Enterprises has caused this instrument of amendment to be executed by its duly authorized officer as of the 22nd day of July, 1998. EASTERN ENTERPRISES By: /s/ J.
