                                   AGREEMENT


         This  Agreement by and between  Eastern  Enterprises,  a  Massachusetts
business trust with its principal offices in Weston,  Massachusetts ("Eastern"),
and Fred C.  Raskin  (the  "Executive"),  is entered  into as of the 22nd day of
September, 1999, and amends and supersedes in its entirety the change of control
agreement between the parties dated September 1, 1998:

                          W I T N E S S E T H T H A T:

         WHEREAS the Executive is an executive employee of Eastern;

         WHEREAS Eastern has previously  executed a separate  agreement dated as
of September 1, 1998 with Executive (the  "Employment  Agreement"),  under which
Eastern has assured  Executive of certain salary and benefit  amounts  following
termination of his employment,  whether in the context of a change of control or
otherwise; and

         WHEREAS the Board of Trustees of Eastern (the  "Board") has  determined
that it is in the best interests of Eastern,  its shareholders and the Executive
to  assure  continuity  in  the  management  of  Eastern's   administration  and
operations by entering  into an agreement to provide the Executive  with certain
assurances pertaining to compensation and benefits in the event that a Change of
Control,  as  defined  below,  should  be under  consideration  or  should  have
occurred.

         NOW,  THEREFORE,  it is hereby agreed by and between the parties hereto
as follows:

         1. EMPLOYMENT. Eastern agrees that from and after the Effective Date as
hereinafter  defined  it shall  continue  the  Executive  in its  employ and the
Executive  agrees that from and after the Effective  Date he shall remain in the
employ of Eastern, in each case for the period described in Section 4 hereof and
upon the other terms and conditions herein provided.

         2. CERTAIN DEFINITIONS:  For purposes of this Agreement,  the following
terms shall have the meanings set forth below:

                  (a) "Cause"  shall  mean,  subject to the  provisions  of this
         definition,  (i)  conviction  of the  Executive  for (or a plea of nolo
         contendere by the Executive  with respect to) a felony,  or (ii) an act
         by the Executive of fraud or dishonesty which has resulted or is likely
         to result in material  economic damage to Eastern or its  subsidiaries.
         No purported termination of Executive shall be deemed a termination for
         Cause  unless  the Board  shall  have made a  determination  that Cause
         exists nor unless,  in the case of Cause  asserted under clause (a)(ii)
         above, the Board shall have given the Executive the  opportunity,  upon
         at least thirty (30) days' prior written notice, to appear and be heard

                  the beneficial owners  immediately prior to such merger of the
                  then outstanding  voting securities of Eastern do not continue
                  to own beneficially at least sixty percent (60%) of the voting

                  or not less than sixty percent (60%) of the voting  securities
                  of  the  entity  or   entities   to  which  such  assets  were
                  transferred by the owners immediately prior to the transfer of
                  the then outstanding voting securities of Eastern; or

                           (iv) within any two-year  period,  individuals who at
                  the beginning of such period constituted the Board of Trustees
                  of  Eastern  cease for any  reason to  constitute  a  majority
                  thereof;  provided,  that any  trustee who is not in office at

                  approval who were either  trustees of Eastern at the beginning
                  of such  period or who were  elected to the Board of  Trustees
                  pursuant to an election which was, or for which the nomination
                  for election was,  previously  so approved  shall be deemed to
                  have been in office at the beginning of such two-year period.

                  (c) "Code"  shall mean the federal  Internal  Revenue  Code of

         salary payable to the Executive  below the higher of the annual rate at
         which base  salary is then being  paid to the  Executive  or the annual

         immediately  prior to the  Effective  Date,  or any  change in any such
         employee or executive benefit, benefit program or perquisite that would
         result in additional cost to the Executive or the  Executive's  family,
         in each  case  except  for  changes  in  broad-based  employee  benefit
         programs (that is, employee benefit  programs  available to non-officer
         employees  generally as well as officers) that have a similar effect on
         both officer and non-officer  participants  generally in such programs;

hereunder,  the  Executive  agrees to serve  Eastern 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 Effective  Date
         and  shall  continue  for a  period  that  ends on the  last day of the
         Protected Period.

                  (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 Eastern 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  to
         Eastern.

         5. COMPENSATION AND BENEFITS.  During the Executive's  employment under
this Agreement, Eastern shall pay, provide and make available the following:

                  (a) Eastern 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  Eastern  immediately  prior  to the
         Effective Date.

                  (b) In addition to the salary  payable  under  subsection  (a)
         above,  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.  Eastern 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 Eastern 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  Eastern  for Cause  (but only if such  termination  is
         accomplished in the manner specified in Section 2(a));

                  (b) by Eastern  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 Eastern 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 Eastern of
the  Executive's  employment  under this Agreement  shall take effect only after
thirty (30) days' prior written notice by Eastern to the Executive.

         8. VESTING OF CERTAIN AWARDS AND BENEFITS.1 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 the 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 terminated or been terminated under Section 7(b)
or Section  7(c)  above on or after the  Effective  Date but before the  related
Change of  Control,  the  immediately  preceding  sentence  shall be  applied by
substituting the words "held by the Executive  immediately  prior to termination
of employment"  for the words "then held by the  Executive".  If the Executive's
employment  under this Agreement shall have terminated or been terminated  under
Section  7(b) or  Section  7(c)  above,  all of the  Executive's  stock  options
(including  replacement  options,  if any, issued in substitution for such stock
options  in  connection  with  the  Change  in  Control)  held by the  Executive
immediately  prior to such  termination  shall be exercisable  for a period that
ends not earlier than the earlier of (i) the date on which the option would have
expired or terminated had the Executive  continued in  employment,  and (ii) the
date which follows the Change of Control by thirteen (13) months; provided, that
clause  (ii) of this  sentence  shall  not  operate  to  extend  the  period  of
exercisability  for any stock option that is intended to be an "incentive  stock
option"  within the  meaning of Section 422 of the Code;  and further  provided,
that if stock options are not assumed (and no replacement options are issued) in
connection  with the Change of Control,  Eastern shall provide the Executive the
opportunity  to exercise  all of the stock  options  then held by the  Executive
(taking  into  account the  provisions  of this  sentence)  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 Eastern
         pursuant to Section 7(b) above,  Eastern 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  Executive's  total  target  benefit  or
                  benefits  under the 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  total 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;  provided, that
                  for purposes of determining the Executive's target benefit for
                  any  portion  of an award  opportunity  as to which no  target
                  amount  is  specified,   (A)  if  the  portion  of  the  award
                  opportunity  as to which no target  benefit is  specified is a
                  financial award opportunity,  then the target benefit for such
                  portion shall be 66 2/3% of the maximum award  opportunity for
                  such portion,  and (B) if the portion of the award opportunity
                  as to which no target  benefit is  specified  is a  management
                  objective or "MBO" award opportunity,  then the target benefit
                  for such portion shall be 75% of the maximum award opportunity
                  for such portion;  and further provided,  that the Executive's
                  total  target  benefit or  benefits  will equal the sum of the
                  separate  portions  of the award  opportunity  as  hereinabove
                  determined; and

                           (iii) a lump sum cash amount  equal to the product of
                  the Executive's total target benefit or benefits (as described
                  at paragraph (ii) above, but determined solely by reference to
                  the  annual  bonus or  incentive  plan or  plans in which  the
                  Executive was  participating for the period including the date
                  of  termination)  times a fraction,  the numerator of which is
                  the number of days elapsed in such bonus or  incentive  period
                  prior to the date of termination, and the denominator of which
                  is three hundred sixty-five (365).

         In addition,  upon termination of employment Eastern 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  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 Eastern  then in effect,
         Eastern shall provide for substantially equivalent alternative coverage
         and   benefits  for  the   Executive   and  the   Executive's   family.
         Notwithstanding  the  foregoing,  Eastern  shall  not be  obligated  to
         provide a benefit or coverage  under the  preceding  provisions of 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.  Immediately following the
         termination  of the benefits  provided under this Section 9(b) whenever
         occurring  (or at any earlier time  subsequent  to the  termination  of
         employment  giving rise to such  benefits),  Eastern  shall  provide or
         cause  to be  provided  to the  Executive  and the  Executive's  family
         retiree health,  dental, life and other retiree benefits,  in each case
         not less favorable  (and on terms not less  favorable) to the Executive
         and the Executive's  family than those  available to eligible  retirees
         and their  families under the retiree  benefit  program of similar type
         (for example, retiree medical benefits or retiree life insurance) as in
         effect  (i)  immediately  prior to the date of the  termination  of the
         Executive's  employment if immediately  prior to that date the benefits
         available  under that program to eligible  retirees and their  families
         were more  favorable  (and were made  available on terms that were more
         favorable) than the benefits and terms,  if any,  available to eligible
         retirees and their families under that program as in effect immediately
         prior to the Effective Date, or (ii) in all other cases,  the Effective
         Date; provided,  that the Executive and the Executive's family shall be
         eligible for retiree benefits under this sentence only if the Executive
         would have been  eligible  to  participate  in the  retiree  program of
         similar type (as in effect  immediately  prior to the Effective Date or
         immediately  prior to the  termination of the  Executive's  employment,
         whichever  provided for more liberal  eligibility  requirements) if (A)
         such program had continued unchanged and the Executive had continued in
         employment  through  the  end  of  the  benefits   continuation  period


         described  in the  first  sentence  of this  Section  9(b)  (determined
         without regard to any early termination of such period  attributable to
         benefits  made  available  by  a  subsequent  employer),  and  (B)  the
         Executive  had then retired.  For purposes of applying the  immediately
         preceding  sentence,  any minimum  age  requirement  applicable  to the
         Executive for  participation in a retiree benefit program of Eastern or
         its  subsidiaries  shall be deemed  satisfied  if, as of the end of the
         benefits  continuation  period  described in the first sentence of this
         Section 9(b)  (determined  without  regard to any early  termination of
         such period  attributable  to benefits  made  available by a subsequent
         employer), the Executive is or would have been at least age 52. Nothing
         in this  paragraph  shall be  construed  as  requiring  Eastern  to pay
         severance in addition to the payments and benefits  otherwise  provided
         for in this Agreement.

                  For a period of twenty-four  (24) months  commencing  with the
         month in which a termination  described in (a)(1) or (a)(2) above shall
         have occurred, the Executive will have the continued use of the company
         provided  vehicle used by the Executive at the time of his  termination
         of  employment.  During such period,  Eastern  will  provide  insurance
         coverage for such vehicle but the Executive will be responsible, at his
         own expense, for all normal costs of operation and maintenance.  At the
         end of such period,  Eastern will afford the Executive the  opportunity
         to purchase  said vehicle at its "blue book" value,  determined  on the
         basis of the most recently issued list of such values.

                  (c)  If  the  Executive  so  requests  in  connection  with  a
         termination  described in (a)(1) or (a)(2)  above,  Eastern will pay in
         accordance  with prior practice the costs of an  out-placement  service
         used by the Executive as a result of such termination.


         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 Eastern in writing,  specifying
         the  amount  of  Gross-Up  Payment  required  and  details  as  to  the
         calculation  thereof.  Eastern 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 Eastern,  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 Eastern,  and whose fees and disbursements
         shall be paid by Eastern.


                  (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  Eastern 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,  Eastern  shall  either  pay the  Gross-Up  Payment or
         provide an opinion from  Independent  Tax Counsel to the  Executive and
         Eastern  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
         Eastern  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 Eastern 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 Eastern,  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  Eastern to pay a
         Gross-Up  Payment,  provided  Eastern  requests  in  writing  that  the
         Executive do so and provides an opinion from Independent Tax Counsel to
         the  Executive  and  Eastern  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 Eastern in writing to do so at any time, in which case the Executive
         shall be entitled to receive from Eastern 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 Eastern, 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 Eastern  acknowledges  its liability
         under this Agreement in the event that the Internal  Revenue Service or
         other tax authority  prevails in the contest.  Eastern 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, Eastern 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 Eastern.


         11. SOURCE OF PAYMENTS.  All payments provided for under this Agreement
shall  be  paid  or  provided  from  the  general  assets  of  Eastern  and  its
subsidiaries  or affiliates (to the extent not provided by  insurance).  Eastern
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  Eastern's  ability to  establish or fund a
so-called  "rabbi  trust"  or  similar  arrangement  to help  Eastern  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 Eastern's  liabilities  hereunder or otherwise adversely affect
the Executive.

         12.  LITIGATION  EXPENSES.  In the  event  of any  litigation  or other
proceeding  between 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),  Eastern
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  Eastern for any of the
costs and expenses relating to such litigation or other proceeding.

         13. INCOME TAX WITHHOLDING. 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. CONFIDENTIAL INFORMATION.  The Executive agrees that, following any
termination of his employment  under this Agreement,  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  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;  OTHER SEVERANCE BENEFITS.  If the severance
pay provisions of Section 5.1 and Section 5.3 of Eastern's  Employee  Salary and
Benefits  Protection  Plan as amended and  restated  September 1, 1999 (the "COC
Severance Plan") (as such provisions would have applied to the Executive had the
Executive  been eligible to  participate  in the COC Severance  Plan) would have
yielded a larger severance pay amount than that determined under paragraphs (i),
(ii)  and  (iii) of  Section  9(a) of this  Agreement,  the  Executive  shall be
entitled under Section 9(a) hereof to such greater  severance pay amount in lieu
of the  formula  amounts  determined  under  Section  9(a)(i),  (ii) and  (iii);
provided,  that such  severance  pay shall  continue  to be subject to the other
terms of this Agreement.  If the benefits continuation provisions of Section 5.2
of the COC  Severance  Plan  (as  such  provisions  would  have  applied  to the
Executive  and  the  Executive's  family  had the  Executive  been  eligible  to
participate in the COC Severance  Plan) would have provided for  continuation of
benefits  at least as good as those  provided  under  this  Agreement  but for a
longer period of time,  the period  described in Section 9(b) of this  Agreement
for the  continuation  of benefits shall be deemed  modified to provide for such
longer period of benefits continuation. Subject to the foregoing, this Agreement
contains the entire understanding between Eastern and the Executive with respect
to the  subject  matter  hereof and  supersedes  any prior  Change of Control or
similar severance or salary  continuation  agreement,  other than the Employment
Agreement, between Eastern 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  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
hereunder.  Upon  such  a  consolidation,  merger  or  transfer  of  assets  and
assumption,  the term "Eastern", 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 under this
Agreement  shall  survive  the  termination  for any  reason  of this  Agreement
(whether such termination is by Eastern,  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 the Executive:

                           Fred C. Raskin
                           1 Andover Country Club Lane
                           Andover, MA  01810

or to such other  address as either  party shall have  previously  specified  in
writing to the other pursuant to this Section 19.

         20. NO  ATTACHMENT.  Except as  required  by law,  no right to  receive
payments under this  Agreement  shall be subject to  anticipation,  commutation,
alienation, sale, assignment, encumbrance, charge, pledge or hypothecation or to
execution,  attachment,  levy or similar  process or  assignment by operation of
law, and any attempt, voluntary or involuntary,  to effect any such action shall
be null, void and of no effect.

         21. BINDING  AGREEMENT.  This Agreement shall be binding upon and shall
inure  to  the  benefit  of the  Executive  and  Eastern  and  their  respective
successors and assigns.


         22.  MODIFICATION AND WAIVER.

                  (a)  Prior  to  the  Effective  Date  this  Agreement  may  be
         modified,  amended or  terminated  by the Board of Trustees of Eastern.
         From and after the Effective  Date this  Agreement may not be modified,
         amended or terminated  except by an instrument in writing signed by the
         parties hereto.

                  (b) No term or condition of this Agreement  shall be deemed to
         have  been  waived,  nor  shall  there  be  any  estoppel  against  the
         enforcement  of any  provision  of this  Agreement  except  by  written
         instrument signed by the party charged with such waiver or estoppel. 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.  GOVERNING  LAW. This  Agreement and its validity,  interpretation,
performance and enforcement shall be governed by the laws of the Commonwealth of
Massachusetts,  without  giving effect to the choice of law provisions in effect
in such State.

         25. MISCELLANEOUS. Reference is hereby made to the declaration of trust
establishing  Eastern  Enterprises  dated July 18, 1929,  as amended,  a copy of
which is on file in the office of the Secretary of State of The  Commonwealth of
Massachusetts.  The name "Eastern Enterprises" refers to the trustees under said
declaration as trustees and not personally, and no trustee, shareholder, officer
or agent of  Eastern  Enterprises  shall be held to any  personal  liability  in
connection  with the affairs of said Eastern  Enterprises,  but the trust estate
only is liable.


         IN WITNESS WHEREOF, Eastern has caused this Agreement to be executed by
its  officers  thereunto  duly  authorized,  and the  Executive  has signed this
Agreement, all as of the date first above written.

                                       EASTERN ENTERPRISES

                                       By: /s/ J. Atwood Ives

                                          /s/ Fred C. Raskin

- --------
1 In the event of a Change of Control  intended to be accounted for as a pooling
of interests,  the following  changes would be made to this Section 8 if similar
changes in Eastern's other Officer Change of Control  Agreements were determined
(by the independent  accounting firm serving as Eastern's  independent  auditors
prior to the Change of Control) to be required to preserve the  availability  of
such accounting treatment: (i) the term "Effective Date" as used in this Section
8 would mean the date that  precedes  the Change of Control by six  months,  and
(ii) the  extended  exercisability  provisions  of the  third  sentence  of this
Section 8 shall not  apply;  however,  options  held by the  Executive  prior to
termination  of employment  under  Section 7(b) or Section 7(c), if  termination
occurs after the Effective  Date but before the Change of Control,  would remain
exercisable  until  thirty  (30) days  following  the Change of Control  (or, if
later,  until they would have been exercisable  without regard to the provisions
of this Section 8), subject to earlier expiration and an accelerated opportunity
to  exercise if the options  are not  assumed  (and no  replacement  options are
issued) in connection with the Change of Control.
