         Pursuant to Section 9 of the Eastern Enterprises  Restricted Stock Plan
for Non-Employee Trustees (the "Plan), the Plan is hereby amended as follows:

1.       The first  sentence of Section 6(c) is amended by inserting  the phrase
         "or Section 11" after the phrase "Section 6(d)" therein.

2.       The first  sentence  of Section  6(e) is amended to provide as follows:
         "In the event that a Participant  resigns from the Board of Trustees or
         declines to stand for re-election to the Board of Trustees,  not due to
         the  Participant's  Disability  (as  hereinafter  defined)  and  not in
         accordance  with a retirement  policy of the Board of Trustees  then in
         effect,  and except as  provided  in  Section  11, the shares of Common
         Stock awarded to such  Participant  under the Plan shall be immediately
         forfeited."

3.       Section  6(f) is amended by adding the phrase  "Except as  provided  in
         Section 11," at the beginning  thereof,  and changing the word "Any" to
         "any" following such phrase.

4.       A new Section 11 is added following current Section 10 of the Plan,
         providing as follows:

         "11.     Effect of a Change of Control

                  Notwithstanding  any  other  provision  of  this  Plan  to the
         contrary,  in the event of a Change of Control (as hereinafter defined)
         of the Association all  outstanding  shares of restricted  Common Stock
         awarded  to  Participants  under  this Plan  shall  become  free of the
         transfer  restrictions  and  forfeiture  provisions  of the  Plan,  and
         certificates  representing  such shares will  thereupon be delivered to
         such  Participants.  A  "Change  of  Control"  will be  deemed  to have
         occurred if, after January 1, 1999, any of the following occurs:

         (a)      any "person" (as such term is used in Sections 13(d) and 14(d)
                  of the  Securities  Exchange Act of 1934, as amended) or group
                  of  "persons"  (as so  defined),  other than the  Association,
                  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 the Association; or


         (b)      there is  consummated  a merger  or  consolidation  ("merger")
                  involving the Association  and  immediately  after such merger
                  the beneficial owners  immediately prior to such merger of the
                  then outstanding  voting  securities of the Association do not
                  continue to own  beneficially  at least sixty percent (60%) of
                  the voting securities of the entity or entities resulting from
                  such merger; or

         (c)      there is  consummated  a sale,  lease,  exchange,  spin-off or
                  other transfer (any of the foregoing,  a "transfer") of all or
                  substantially all of the assets or business of the Association
                  and its subsidiaries,  other than any such transfer  resulting
                  in  beneficial  ownership of not less than sixty percent (60%)
                  of 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 the Association; or

         (d)      within any two-year period, individuals who at the beginning
                  of such period constituted the Board of Trustees of the
                  Association cease for any reason to constitute a majority
                  thereof; provided, that any trustee who is not in office at
                  the beginning of such two-year period but whose election or
                  nomination for election was approved by a vote of at least
                  two-thirds of the trustees in office at the time of such
                  approval who were either trustees of the Association 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."


         IN WITNESS WHEREOF, Eastern Enterprises has caused this Amendment to be
executed by its duly authorized officer this 22nd day of September, 1999.
