                      EASTERN ENTERPRISES AND SUBSIDIARIES
                          NOTES TO FINANCIAL STATEMENTS
                                 March 31, 1998


1.  Accounting policies

It is Eastern's opinion that the financial  information contained in this report
reflects all  adjustments  necessary to present a fair  statement of results for
the period reported.  All of these adjustments are of a normal recurring nature.
Results for the period are not necessarily  indicative of results to be expected
for the year, due to the seasonal nature of Eastern's operations. All accounting
policies  have been  applied in a manner  consistent  with prior  periods.  Such
financial  information  is subject to year-end  adjustments  and annual audit by
independent public accountants.

The preparation of financial  statements in conformity  with generally  accepted
accounting principles requires management to make estimates and assumptions that
affect the  reported  amounts  of assets  and  liabilities,  the  disclosure  of
contingent  assets and  liabilities at the date of the financial  statements and
the  reported  amounts of revenues  and expenses  during the  reporting  period.
Actual results could differ from those estimates.

Certain  information  and footnote  disclosures  normally  included in financial
statements prepared in accordance with generally accepted accounting  principles
have been  condensed  or  omitted  in this Form 10-Q.  Therefore  these  interim
financial  statements  should be read in conjunction  with Eastern's 1997 Annual
Report filed on Form 10-K with the Securities and Exchange Commission.

Earnings per share

Basic  earnings  per  share is based on the  weighted  average  number of shares
outstanding.  Diluted  earnings  per share gives effect to the exercise of stock
options using the treasury stock method, as reflected below:

3.  Debt

In March 1998, Midland utilized currently  available cash to call $50 million of
9.9% First Preferred Ship Mortgage Bonds, due 2008. In extinguishing  this debt,
Midland recognized an extraordinary charge of $2,254,000 pretax, $1,465,000 net,
or $.07 per share.

Midland has  entered  into a treasury  rate lock in order to hedge the  interest
rate on long-term debt  anticipated to be issued in late 1998. The treasury rate
lock is for $20 million at a 10-year  treasury rate of 5.617%.  Upon issuance of
the debt,  any gain or loss realized on the treasury rate lock will be amortized
to interest expense over the term of the related debt.

Boston Gas



The  decrease in Boston Gas  revenues  was  primarily  attributable  to the pass
through of lower gas costs ($25  million) and the  migration  of customers  from
firm sales to transportation-only  services ($12 million),  factors that have no
impact on Boston Gas' operating  earnings.  The Company earns all of its margins
on the local  distribution of gas and none on the sale of the commodity  itself.
The revenue  decrease also reflects 4% warmer weather ($10  million),  partially
offset by higher non-firm sales and growth in throughput.  Weather for the first
quarter of 1998 was 11% warmer than normal.

Operating  earnings  for  1998  increased  by  $2.8  million,  reflecting  lower
operating costs ($4 million),  higher average rates and the impact of throughput
growth, partially offset by the margin impact of warmer weather ($3 million) and
the absence of a pension  settlement  gain  reflected in 1997 ($2 million).  The
decrease in operating costs reflects weather-related reductions and cost control
measures.

Midland Enterprises

Weak export grain and coal markets  continued to place downward pressure on spot
and  contract  renewal  rates,  contributing  to a 3% decline  in first  quarter
revenues.  Offsetting this market weakness, lower fuel prices and improved river
conditions contributed to a 12% increase in operating earnings.

Thirty-year record flood levels in March of 1997 severely impacted operations on
the Ohio River and its tributaries and significantly  increased operating costs.
1998  operating  conditions  in these areas have been more  normal,  although El
Nino-related  weather  patterns  caused  delays and  flooding in  Midland's
southeastern and Gulf operations,  impacting  operating  efficiencies and costs,
while also reducing winter heating related coal demand throughout the Midwest.




                                                                Form 10-Q

First quarter tonnage  increased 9% over 1997,  while related ton miles declined
5%, reflecting  increased utility demand from existing  customers as well as new
multi-year  industrial coal contracts.  Coal ton miles were unchanged from 1997,
reflecting  shorter  average  trip  lengths and weaker  demand for export  coal.
Non-coal  tonnage and ton miles  declined 6% and 9%,  respectively,  as compared
with 1997,  primarily reflecting weak export grain demand and reduced towing for
other carriers.

Other

ServicEdge's  operating  loss of $2.1  million  for the  first  quarter  of 1998
reflects  general  and  administrative   expenses  in  preparation  for  serving
customers beginning in April 1998.

In 1997,  other income includes a loss of $1.3 million,  representing  Eastern's
share of AllEnergy's operating losses.  Eastern sold its investment in AllEnergy
in December 1997.

In 1998, other, net includes realized gains on investments of $1.1 million.

In March 1998,  Eastern recognized an extraordinary loss of $2.3 million pretax,
$1.5 million net, or $.07 per share on the early  extinguishment  of $50 million
of Midland debt, as discussed in Note 2 of Notes to Financial Statements.

In March  1998,  the U.S.  Supreme  Court  heard  oral  arguments  in  Eastern's
challenge to the  constitutionality  of the Coal Industry Retiree Health Benefit
Act of 1992 as applied to  Eastern.  The Supreme  Court's  ruling is expected by
June 30, 1998.

FORWARD-LOOKING INFORMATION

This report and other company statements 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: the effect of strategic  initiatives on
earnings  and cash  flow,  temperatures  above or below  normal in  Boston  Gas'
service area,  changes in market  conditions for barge  transportation,  adverse
weather  and  operating  conditions  on  the  inland  waterways,   uncertainties
regarding  the start-up of  ServicEdge,  including  expense  levels and customer
acceptance,  changes in economic  conditions,  including  interest rates and the
value of the dollar versus other currencies,  regulatory and court decisions and
developments  with respect to Eastern's  previously-disclosed  environmental and
Coal Act liabilities.  Most of these factors are difficult to predict accurately
and are generally beyond Eastern's control.

LIQUIDITY AND CAPITAL RESOURCES

Management  believes that projected cash flows from  operations,  in combination
with currently  available  resources and the borrowing discussed below, are more
than  sufficient to meet Eastern's 1998 capital  expenditure and working capital
requirements,  potential funding of its Coal Act and environmental  liabilities,
normal debt repayments and anticipated dividend payments to shareholders.

Consolidated  capital  expenditures  are budgeted at approximately  $110
million,  with about 55% at Boston Gas and the balance at Midland.

As discussed in Note 2, in March 1998, Midland utilized currently available cash
to call $50  million of 9.9% First  Preferred  Ship  Mortgage  Bonds,  due 2008.
Midland currently expects to borrow up to $75 million later in 1998 to refinance
the called  debt and to fund  capital  expenditures  for barges  during 1998 and
1999.  Midland  has  entered  into a  treasury  rate  lock in order to hedge the
interest rate for $20 million of this debt, as discussed in Note 2.

results  for the  period  reported.  All of  these  adjustments  are of a normal
recurring  nature.  Results  for the period are not  necessarily  indicative  of
results to be expected  for the year,  due to the  seasonal  nature of Eastern's
operations.  All  accounting  policies have been applied in a manner  consistent
with  prior  periods.   Such  financial   information  is  subject  to  year-end
adjustments and annual audit by independent public accountants.

Eastern  has  duly  caused  this  report  to be  signed  on  its  behalf  by the
