Exhibit 10.4

                                    AGREEMENT

     This Agreement by and between Eastern Enterprises, a Massachusetts business
trust  with its  principal  offices in Weston,  Massachusetts  ("Eastern"),  and
Walter J.  Flaherty  (the  "Executive"),  is entered  into as of the 22nd day of
July, 1998:

                                WITNESSETH THAT:

     WHEREAS the Executive is an executive employee of Eastern; 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

         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
         with counsel before the Board.

         (b)  "Change  of  Control"  shall  mean  the  occurrence  of any of the

                  becomes  a  beneficial   owner   directly  or   indirectly  of
                  securities  representing  twenty-five percent (25%) or more of
                  the  combined  voting  power  of the then  outstanding  voting
                  securities of Eastern; or

                  (ii) there is consummated a merger or consolidation ("merger")
                  involving  Eastern  and  immediately  after  such  merger  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

                  the assets or business so  transferred  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

                  two-thirds  of the  trustees  in  office  at the  time of such
                  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

         Executive:  (i) any reduction in the annual rate of base 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 rate at which
         base salary was being paid to the  Executive  immediately  prior to the
         Effective  Date;  (ii) the elimination of or any reduction in the bonus
         opportunities  made  available  to the  Executive  under  any  bonus or

         other employee or executive benefit, benefit program or perquisite then
         available  to the  Executive  or the  Executive's  family  or that  was
         available to the Executive or the Executive's  family 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;  (iv) any material  change in
         the  Executive's  duties,  functions  or  responsibilities   (including
         without  limitation  reporting  lines);  (v) any action  resulting in a

         Executive  was  regularly   employed   immediately   prior  thereto  or
         immediately  prior to the Effective  Date;  and (vi) any other material
         breach of this Agreement by Eastern.

     3. POSITION AND  RESPONSIBILITIES.  During the period of employment
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 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  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.  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 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  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   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 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 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  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 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.  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  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 he 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 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 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:

     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.
