                   EASTERN CONSIDERING STRATEGIC ALTERNATIVES


         WESTON,  Massachusetts -- August 16, 1999 -- Eastern Enterprises (NYSE:
EFU) announced  today that it is beginning the process of evaluating a number of
strategic and financial  alternatives to enhance  shareholder value. The process
will include an assessment of its current strategy of consolidating  New England
gas distribution utilities, as well as consideration of share repurchases and/or
other  strategic  transactions,  including  joint  ventures  or sale of all or a
portion of the Company.
         J.  Atwood  Ives,  Eastern's  chairman  and  chief  executive  officer,
comments,  "We  have  made  substantial  progress  in  achieving  our  strategic
objective  of  consolidating  New England  gas  distribution  companies  for the
benefit of both our customers and  shareholders.  Upon completion of the pending
mergers  with  Colonial  Gas,  expected  to  close  at the  end of  August,  and
EnergyNorth,  expected to close mid-2000,  Eastern will own and operate,  in the
aggregate,  the largest natural gas distribution  company in New England serving
over 800,000 customers throughout  Massachusetts and New Hampshire. It also owns
and operates the nation's  second largest inland marine  transportation  company
and several  non-regulated  businesses that complement its LDC operations.  As a
result of the  dramatic  changes  taking  place  within  the  utility  industry,
Eastern's  Board of Trustees  and  management  believe now is a prudent  time to
undertake a review of all of Eastern's options."
         The Company has retained Salomon Smith Barney to assist Eastern's Board
of Trustees and management in its review of strategic alternatives.



         Eastern  Enterprises  owns and operates  Boston Gas Company,  Essex Gas
Company,  Midland Enterprises Inc. and ServicEdge Partners, Inc. Upon completion
of the pending  mergers with  Colonial Gas and  EnergyNorth,  Eastern will serve
over 800,000 natural gas customers in Massachusetts and New Hampshire.  Midland,
headquartered  in Cincinnati,  Ohio, is the leading  carrier of coal and a major
carrier of other dry bulk cargoes on the nation's inland  waterways.  ServicEdge
is the largest unregulated  provider of residential HVAC equipment  installation
and service to customers in Massachusetts.
         This release and other company  reports and  statements  issued or made
from  time to  time  contain  certain  "forward-looking  statements"  concerning
projected future  financial  performance,  expected plans or future  operations.
Eastern cautions that actual results and developments may differ materially from
such projections or expectations.
         Investors should be aware of important  factors that could cause actual
results  to  differ   materially   from  the   forward-looking   projections  or
expectations.  These  factors  include,  but are not limited to:

     o the effect of pending  mergers on  earnings  and cash flow and of
       adopting  any new  strategic initiatives,

     o  Eastern's  ability  successfully  to  integrate  its  new  gas
        distribution  operations,

     o  temperatures  above or  below  normal  in  eastern Massachusetts,

     o changes  in market  conditions  for  barge  transportation,

     o adverse   weather  and  operating   conditions  on  the  inland
       waterways,

     o uncertainties  regarding  the  ultimate  profitability  of  ServicEdge,

     o  the timetable and cost for  completion of Eastern's year 2000 plans,

     o the impact of third  parties' year 2000 issues,

     o changes in economic  conditions,  including interest rates and the value
       of the dollar versus other currencies,

     o regulatory and  court   decisions,   and

     o developments   with   respect  to   Eastern's previously-disclosed
       environmental liabilities.


         Most of these factors are difficult to accurately  predict and many are
beyond the control of the Company.
