POSITION AND RESPONSIBILITIES. During the period of employment hereunder, the Executive agrees to serve Boston Gas in an executive capacity, subject to the terms of this Agreement. 4. TERM AND DUTIES. (a) The period of the Executive's employment under this Agreement shall be deemed to have commenced as of the date (the "Effective Date") which precedes by six (6) months the date of a Change of Control and shall continue for a period which ends on the last day of the twenty-four (24) calendar month period which begins on the date of such Change of Control. (b) During the period of employment hereunder and except for illness or incapacity and reasonable vacation periods, the Executive's business time, attention, skill and efforts shall be exclusively devoted to the business and affairs of Boston Gas and its subsidiaries; provided, however, that nothing in this Agreement shall preclude the Executive from engaging in the following: (i) serving as a director, trustee or committee member in any company or organization, (ii) delivering lectures and fulfilling speaking engagements, and (iii) engaging in charitable and community activities, provided that such activities do not materially adversely affect or interfere with the performance of the Executive's obligations under this Agreement. 5. COMPENSATION AND BENEFITS. During the Executive's employment under this Agreement, Boston Gas (or, to the extent provided below, Eastern) shall pay, provide and make available the following: (a) Boston Gas shall pay the Executive base salary at an annual rate that is not less than the annual rate at which base salary was being paid to the Executive by Boston Gas immediately prior to the Effective Date. (b) In addition to the salary payable under subsection (a) above, Boston Gas and Eastern shall provide or make available to the Executive, from and after the Effective Date and during the term of the Executive's employment hereunder, bonus opportunities, benefits, and perquisites not less favorable, and on terms not less favorable, to the Executive than the bonus opportunities, benefits and perquisites provided or made available and on the terms provided or made available to the Executive immediately prior to the Effective Date. 6. BUSINESS EXPENSE. Boston Gas shall pay or reimburse the Executive for all reasonable travel or other expenses incurred in connection with the performance of the Executive's duties under this Agreement in accordance with such procedures as Boston Gas may from time to time establish. 7. TERMINATION OF EMPLOYMENT. Notwithstanding any other provision of this Agreement, the Executive's employment under this Agreement may be terminated: (a) by Boston Gas for Cause (but only if such termination is accomplished in the manner specified in Section 2(a)); (b) by Boston Gas other than for Cause pursuant to Section 7(a) and other than on account of Disability or death; (c) by the Executive for Good Reason; (d) by the Executive other than for Good Reason, Disability or death; or (e) by Boston Gas or the Executive by reason of the Executive's Disability or death. Except in the case of termination by reason of the Executive's death or termination for Cause pursuant to Section 7(a), any termination by Boston Gas of the Executive's employment under this Agreement shall take effect only after thirty (30) days' prior written notice by Boston Gas to the Executive. 8. VESTING OF CERTAIN AWARDS AND BENEFITS. In the event of a Change of Control, the Executive shall be immediately vested in all shares of restricted stock of Eastern then held by Executive, and all stock options then held by the Executive that were awarded under Eastern's 1982 Stock Option Plan or 1995 Stock Option Plan (or any successor plan or plans) and that were not then exercisable shall become immediately exercisable. If the Executive's employment under this Agreement shall have been terminated under Section 7(b) or Section 7(c) above after the Effective Date but before the Change of Control, all shares of restricted stock held by the Executive immediately prior to termination of employment shall be vested and all stock options held by the Executive immediately prior to termination of employment (including replacement options, if any, issued in substitution for such stock options in connection with the Change of Control), whether or not otherwise exercisable, shall be exercisable for a period ending not earlier than the later of (i) the date such options would have been exercisable without regard to this Section 8, or (ii) thirty days following the Change of Control, subject in each case to consummation of the Change of Control; provided, that if stock options are not assumed (and no replacement options are issued) in connection with the Change of Control, clause (ii) shall not apply and Eastern shall provide the Executive the opportunity to exercise all of the stock options held by the Executive immediately prior to termination of employment (whether or not then exercisable) on the same basis as options held by active employees that become exercisable in connection with the Change of Control. The provisions of this Section 8 shall be in addition to, and not in limitation of, any rights that Executive may otherwise have to the vesting of benefits upon a Change of Control. Without limiting the foregoing, this Agreement shall be treated as a "COC Agreement" for purposes of the Eastern Enterprises Supplemental Executive Retirement Plan and the Eastern Enterprises Supplemental Retirement Plan for Certain Officers, each as from time to time amended. 9. PAYMENTS UPON TERMINATION OF EMPLOYMENT. (a) In the event of any termination of the Executive's employment during the term of this Agreement, if such termination is (1) by the Executive pursuant to Section 7(c), above, or (2) by Boston Gas pursuant to Section 7(b) above, Boston Gas shall pay to the Executive the sum of the following amounts within 30 days of such termination (provided, that if such termination of employment occurs after the Effective Date but before the Change of Control, the Executive shall be entitled to the payments described at (i), (ii) and (iii) below only upon consummation of the Change of Control): (i) a lump sum cash amount equal to the product of three (3) times the annual rate at which the Executive was being paid base salary immediately prior to such termination or immediately prior to the Effective Date, if greater; (ii) a lump sum cash amount equal to the product of three (3) times the target benefit or benefits under the Executive's annual bonus or incentive plan or plans in which the Executive was participating for the period including the date of termination or times the Executive's target benefit or benefits under the annual bonus or incentive plan or plans in which the Executive was participating for the period including the Effective Date if higher; and (iii) a lump sum cash amount equal to the product of (A) the Executive's target benefit or benefits for the bonus or incentive period or periods that include the date of termination (under the annual bonus or incentive plan or plans in which the Executive was participating at the time of termination), times a (B) a fraction, the numerator of which is the number of days elapsed in such bonus or incentive period or periods prior to the date of termination, and the denominator of which is three hundred sixty-five (365). In addition, upon termination of employment Boston Gas shall promptly pay to the Executive any salary, bonuses, or other payments earned by the Executive but not yet paid as of the date of termination. (b) For a period of thirty-six (36) months commencing with the month in which a termination described in (a)(1) or (a)(2) above shall have occurred, the Executive and the Executive's family shall continue to be entitled to participate in Boston Gas's or Eastern's medical, dental, life-insurance, disability and other welfare benefit plans and programs at a level of benefits at least as favorable to the Executive and the Executive's family, and on terms at least as favorable to the Executive and the Executive's family, as were available to the Executive and the Executive's family immediately prior to termination or immediately prior to the Effective Date (whichever is more favorable to the Executive and the Executive's family). For purposes of any such benefit that is based on the Executive's length of employment, the Executive shall be deemed credited with three (3) additional years of employment. For purposes of any such benefit that is based on the Executive's average compensation, the average taken into account shall not be less than the average that would be determined by assuming continued base salary and bonus or incentive payments for a period of three (3) years at the rates described at Section 9(a) above, and for purposes of any such benefit that is based on the Executive's compensation at termination of employment, there shall be taken into account the higher of the Executive's compensation at termination or the Executive's compensation immediately prior to the Effective Date. To the extent the continuation of benefits described in this paragraph cannot be accommodated under the plans or programs of Boston Gas or Eastern then in effect, Boston Gas shall provide for substantially equivalent alternative coverage and benefits for the Executive and the Executive's family. Notwithstanding the foregoing, Boston Gas shall not be obligated to provide a benefit or coverage under this paragraph to the extent an equivalent or better benefit or coverage is available to the Executive or the Executive's family, on a basis that is at least as favorable to the Executive and the Executive's family, under a plan or program of another employer. Nothing in this paragraph shall be construed as requiring Boston Gas or Eastern to pay severance in addition to the payments and benefits otherwise provided for in this Agreement. 10. CERTAIN TAX-RELATED PAYMENTS. (a) In the event it shall be determined that any "payment in the nature of compensation" (as that term is used in Section 280G of the Code) to or for the benefit of the Executive, whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise (a "Payment"), would be subject to the excise tax imposed by Section 4999 of the Code or comparable state or local tax or any interest or penalties with respect to such excise tax or comparable state or local tax (such excise tax, together with any such interest and penalties, are hereinafter collectively referred to as the "Excise Tax"), then, subject to the following sentence, the cash payments described at Section 9(a)(i), (ii) and (iii) hereof (but excluding, for the avoidance of doubt, any payments referred to in the last sentence of Section 9(a)) shall be reduced, but not below zero, to the extent (and only to the extent) necessary to avoid the imposition of an Excise Tax. Notwithstanding the foregoing, if the preceding sentence would result in a reduction of more than ten percent (10%) in the Executive's total"parachute payments" (as that term is defined in Section 280G(b)(2) of the Code), or if the reduction described in the preceding sentence would not eliminate the Excise Tax, no reduction shall be made in the payments or benefits due to the Executive under this Agreement or otherwise and instead the Executive shall be entitled to receive an additional payment (a "Gross-Up Payment"). The Gross-Up Payment shall be equal to the sum of the Excise Tax and all taxes (including any interest or penalties imposed with respect to such taxes) imposed upon the Gross-Up Payment. (b) If the Executive determines that a Gross-Up Payment is required, the Executive shall so notify Boston Gas in writing, specifying the amount of Gross-Up Payment required and details as to the calculation thereof. Boston Gas shall, within 30 days, either pay such Gross-Up Payment (net of applicable wage withholding) to the Executive or furnish an unqualified opinion from Independent Tax Counsel (as defined below), addressed to the Executive and Boston Gas, that there is substantial authority (within the meaning of Section 6661 of the Code) for the position that no Gross-Up Payment is required. "Independent Tax Counsel" means a lawyer with expertise in the area of executive compensation tax law, who shall be selected by the Executive and shall be reasonably acceptable to Boston Gas, and whose fees and disbursements shall be paid by Boston Gas. (c) If the Internal Revenue Service or other tax authority proposes in writing an adjustment to the income tax of the Executive which would result in a Gross-Up Payment, the Executive shall promptly notify Boston Gas in writing and shall refrain for at least thirty days after giving such notice, if so permitted by law, from paying any tax (including interest, penalties and additions to tax) asserted to be payable as a result of such proposed adjustment. Before the expiration of such period, Boston Gas shall either pay the Gross-Up Payment or provide an opinion from Independent Tax Counsel to the Executive and Boston Gas as to whether it is more likely than not that the proposed adjustment would be successfully challenged if the matter were to be litigated. If the opinion provides that a challenge would be more likely than not to be successful if the issue were litigated, and Boston Gas requests in writing that the Executive contest such proposed adjustment, then the Executive shall contest the proposed adjustment and shall consult in good faith with Boston Gas with respect to the nature of all action to be taken in furtherance of the contest of such proposed adjustment; provided that the Executive, after such consultation with Boston Gas, shall determine in his sole discretion the nature of all action to be taken to contest such proposed adjustment, including (A) whether any such action shall initially be by way of judicial or administrative proceedings, or both (B) whether any such proposed adjustment shall be contested by resisting payment thereof or by paying the same and seeking a refund thereof, and (C) if the Executive shall undertake judicial action with respect to such proposed adjustment, the court or other judicial body before which such action shall be commenced and the court or other judicial body to which any appeals should be taken. The Executive agrees to take appropriate appeals of any judicial decision that would require Boston Gas to pay a Gross-Up Payment, provided Boston Gas requests in writing that the Executive do so and provides an opinion from Independent Tax Counsel to the Executive and Boston Gas that it is more likely than not that the appeal would be successful. The Executive further agrees to settle, compromise or otherwise terminate a contest with the Internal Revenue Service or other tax authority with respect to all or a portion of the proposed adjustment giving rise to the Gross-Up Payment, if requested by Boston Gas in writing to do so at any time, in which case the Executive shall be entitled to receive from Boston Gas the Gross-Up Payment. In no event shall the Executive compromise or settle all or any portion of a proposed adjustment which would result in a Gross-Up Payment without the written consent of Boston Gas, which consent shall not be unreasonably withheld. The Executive shall not be required to take or continue any action pursuant to this Section 10 unless Boston Gas acknowledges its liability under this Agreement in the event that the Internal Revenue Service or other tax authority prevails in the contest. Boston Gas hereby agrees to indemnify the Executive in a manner reasonably satisfactory to the Executive for any fees, expenses, penalties, interest or additions to tax which the Executive may incur as a result of contesting the validity of any Excise Tax and to reimburse the Executive promptly upon receipt of a written demand of the Executive for all costs and expenses which the Executive may incur in connection with contesting such proposed adjustment (including reasonable fees and disbursements of Independent Tax Counsel). If the Executive shall have contested any proposed adjustment as above provided, and for so long as the Executive shall be required under the terms of this Section 10(c) to continue such contest, Boston Gas shall not be required to pay a Gross-Up Payment until there occurs a Final Determination (as defined below) of the liability of the Executive for the tax and any interest, penalties and additions to tax asserted to be payable as a result of such proposed adjustment. A "Final Determination" shall mean (A) a decision, judgment, decree or other order by any court of competent jurisdiction, which decision, judgment, decree or other order has become final after all allowable appeals by either party to the action have been exhausted, the time for filing such appeal has expired or the Executive has no right under the terms hereof to request an appeal, (B) a closing agreement entered into under Section 7121 of the Code or any other settlement agreement entered into in connection with an administrative or judicial proceeding and with the consent of the Executive, or (C) the expiration of the time for instituting a claim for refund, or if such a claim was filed, the expiration of the time for instituting suit with respect thereto. (d) In the event the Executive receives any refund from the Internal Revenue Service or other tax authority on account of an overpayment of Excise Tax, such amount, together with that part of any Gross-Up Payment attributable to such amount, shall be promptly paid by the Executive to Boston Gas. 11. SOURCE OF PAYMENTS. Except as provided at Section 8 above, all payments provided for under this Agreement shall be paid or provided from the general assets of Boston Gas and its subsidiaries or affiliates (to the extent not provided by insurance). Boston Gas shall not be required to establish a special or separate fund or other segregation of assets to assure such payments. Nothing in this Section, however, shall be construed as restricting Boston Gas's ability to establish or fund a so-called "rabbi trust" or similar arrangement to help Boston Gas meet its liabilities hereunder, provided that the establishment or funding of such a trust or arrangement does not by its terms or by operation of law limit or purport to limit Boston Gas's liabilities hereunder or otherwise adversely affect the Executive. 12. LITIGATION EXPENSES. In the event of any litigation or other proceeding between Boston Gas or Eastern and the Executive with respect to the subject matter of this Agreement and the enforcement of rights asserted in good faith hereunder, or, in the event of termination of employment pursuant to Section 7(b) or Section 7(c) above, with respect to any other remuneration or benefits with respect to the Executive (including, without limitation, payments or benefits with respect to the Executive under any qualified or nonqualified pension or retirement agreement, plan, policy, program or arrangement), Boston Gas shall reimburse the Executive for all costs and expenses relating to such litigation or other proceeding, including reasonable attorneys fees and expenses, promptly upon receipt of a written demand therefor and regardless of whether such litigation results in any settlement or judgment or order in favor of any party. Notwithstanding any provision of Massachusetts law to the contrary, in no event shall the Executive be required to reimburse Boston Gas or Eastern for any of the costs and expenses relating to such litigation or other proceeding. 13. INCOME TAX WITHHOLDING. Boston Gas and Eastern may withhold from any payments made under this Agreement all federal, state, city or other taxes as shall be required pursuant to any law or governmental regulation or ruling. 14. AGREEMENT NOT TO COMPETE, ETC. The Executive agrees that during the 36-month period beginning on the date the Executive's employment with Eastern and its subsidiaries, including Boston Gas, is terminated during the term hereof pursuant to Section 7(b) or Section 7(c) above, he will not, within the states in which Eastern operates its business or in which any of Eastern's subsidiaries operates its business, engage, either as a principal, employee, partner, consultant or investor (other than through a 1 % or smaller interest in a publicly traded entity) in a business which competes with any such business of Eastern or its subsidiaries. The Executive further agrees that, following any such termination of his employment, he will continue to comply with Eastern's policies and procedures regarding confidential information, as that term is hereinafter defined, and will never directly or indirectly use or disclose, except to the Executive's attorney or as required by judicial or regulatory process or order, any confidential information as so defined. For purposes of this paragraph, the term "confidential information" means any and all information (including without limitation information related to the development and implementation of business strategy, financial and operating forecasts, business policies and practices, and all other information related to the future conduct of business) (i) that the Executive has acquired in connection with his employment with Eastern and its subsidiaries, (ii) that is not generally known or available to others with whom Eastern or its subsidiaries do, or plan to, compete or do business, and (iii) that pertains to the business of, or belongs to, Eastern or its subsidiaries or a person described in clause (ii). The Executive agrees that if, at any time, pursuant to action of any court of competent jurisdiction, the operation of any part of this Section 14 shall be determined to be unlawful or otherwise unenforceable, then the coverage of this Section 14 shall be deemed to be restricted as to duration, geographical scope or otherwise, to the extent, but only to the extent, necessary to make this paragraph lawful and enforceable in the particular jurisdiction in which such determination is made. The Executive acknowledges and agrees that, were he to breach the provisions of this Section 14, the harm to Eastern and its subsidiaries would be irreparable. The Executive therefore agrees that in the event of such a breach or threatened breach, Eastern or its subsidiaries shall have the right to obtain preliminary and permanent injunctive relief against any such breach without having to post bond. Nothing herein shall prohibit Eastern or its subsidiaries from seeking damages for a breach by the Executive of this Section 14, but neither Eastern nor any other person shall withhold or offset any payments or benefits due or owing to the Executive under the terms of this Agreement or otherwise (including, without limitation, payments or benefits with respect to the Executive under any qualified or nonqualified pension or retirement agreement, plan, policy, program or arrangement), and all such payments and benefits shall be promptly paid or provided to the Executive in accordance with the terms of this Agreement (or such other agreement, plan, policy, program or arrangement, as the case may be) without regard to any breach or alleged or threatened breach by Executive of any provision of this Section 14. 15. ENTIRE UNDERSTANDING. This Agreement contains the entire understanding between Eastern, Boston Gas and the Executive with respect to the subject matter hereof and supersedes any prior Change of Control or similar severance or salary continuation agreement between Boston Gas or Eastern (including any of Eastern's subsidiaries other than Boston Gas) and the Executive. 16. SEVERABILITY. If, for any reason, any one or more of the provisions or part of a provision contained in this Agreement shall be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provision or part of a provision of this Agreement not held so invalid, illegal or unenforceable, and each other provision or part of a provision shall to the full extent consistent with law continue in full force and effect. 17. CONSOLIDATION, MERGER OR SALE OF ASSETS. Nothing in this Agreement shall preclude Eastern or Boston Gas from consolidating or merging into or with, or transferring all or substantially all of its assets to, another person that assumes this Agreement and all obligations and undertakings of Eastern or Boston Gas, respectfully, hereunder. Upon such a consolidation, merger or transfer of assets and assumption, involving Eastern or Boston Gas, the terms "Eastern" and "Boston Gas", respectfully, as used herein shall mean such other person and this Agreement shall continue in full force and effect. 18. SURVIVAL OF OBLIGATIONS. The obligations of Eastern and Boston Gas under this Agreement shall survive the termination for any reason of this Agreement (whether such termination is by Eastern, by Boston Gas, by the Executive, upon the expiration of this Agreement or otherwise). 19. NOTICES. All notices, requests, demands and other communications required or permitted hereunder shall be given in writing and shall be deemed to have been duly given if delivered or mailed, registered or certified, postage prepaid with return receipt requested, as follows: (a) To Eastern: Eastern Enterprises 9 Riverside Road Weston, MA 02493 Attention: Legal Department (b) To Boston Gas: Boston Gas Company One Beacon Street Boston, MA 02108 Attention: Legal Department (with a copy to Eastern) (c) To the Executive: Chester R.

No such written waiver shall be deemed a continuing waiver unless specifically stated therein, and each such waiver shall operate only as to the specific term or condition waived and shall not constitute a waiver of such term or condition for the future or as to any act other than that specifically waived. 23. HEADINGS OF NO EFFECT. The paragraph headings contained in this Agreement are included solely for convenience of reference and shall not in any way affect the meaning or interpretation of any of the provisions of this Agreement. 24.
