                      EASTERN ENTERPRISES AND SUBSIDIARIES
                          NOTES TO FINANCIAL STATEMENTS
                               September 30, 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 periods reported. All of these adjustments are of a normal recurring nature.
Results for the periods 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.  As
discussed in Note 2, amounts have been  restated  under the pooling of interests
method of  accounting  to include  the  operations  of Essex  County Gas Company
("Essex Gas"). 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,  as  adjusted  to account  for the Essex Gas  acquisition.  Diluted
earnings  per share  gives  effect to the  exercise of stock  options  using the
treasury stock method, as reflected below:

2.  Essex County Gas Company Merger

On September 30, 1998,  Eastern  completed a merger with Essex Gas by exchanging
approximately  2,047,000  shares of its common stock for all of the common stock
of Essex  Gas.  Each share of Essex Gas was  exchanged  for  1.183985  shares of
Eastern  common  stock.  The merger was accounted for as a pooling of interests.
Accordingly, the accompanying financial statements include the accounts of Essex
Gas for all periods presented.

Essex  Gas's  fiscal  year  ends on August  31.  Accordingly,  the  accompanying
financial  statements  include the three and nine month periods ending September
30, 1998 of Eastern combined with the three and nine month periods ending August

1997 of Eastern  combined with the three and nine month  periods  ending May 31,
1997 of Essex Gas.

Financial results for the separate  companies and the combined amounts presented

The combined financial  statements include adjustments to conform the accounting
policies of Essex Gas with those of Eastern.  The primary  adjustment  conformed
Essex Gas's method of adoption of Statement  of Financial  Accounting  Standards
("SFAS") No. 106, "Employers' Accounting for Postretirement  Benefits Other Than
Pensions" with  Eastern's  adoption by  immediately  recognizing  the transition
obligation of approximately  $4.1 million at the date of adoption,  September 1,
1994. Since Essex Gas had received regulatory approval to fully recover the SFAS
No. 106 costs in rates,  a  regulatory  asset was  recorded  for the  transition
obligation and there was no adjustment to income.

Transaction fees are expected to total $9,500,000, of which $3,358,000 have been
incurred and expensed for the nine month period  ending  September  30, 1998. An
additional $300,000 of transaction fees were incurred and expensed in the fourth
quarter of the prior year.  The remaining  $5,842,000  will be expensed by Essex
Gas in September 1998.  Transaction fees primarily  include  investment  banking
fees and other professional fees.

In conjunction with the approval of the merger by the  Massachusetts  Department
of  Telecommunication  and Energy (the "DTE"),  a rate plan,  whereby  Essex Gas
customers  receive an immediate 5% rate  reduction  and base rates remain frozen
for ten  years,  was also  approved.  Because of the rate  freeze,  Essex Gas is
unable to continue its  application of SFAS No. 71,  "Accounting for the Effects
of Certain Types of Regulation" and, effective September 30, 1998 will write-off
net regulatory assets  approximating  $2,950,000 pretax,  $1,200,000 net or $.05
per share.  Regulatory  assets primarily  consisted of deferred  post-retirement
health care costs.  In  addition,  Essex Gas will be required to adopt a revenue
method which will reflect full accrual  accounting  which will result in a minor
non-recurring  gain.  The  impact  of  these  changes  is not  reflected  in the
accompanying  consolidated  financial statements as a result of differing fiscal
year ends discussed above.

3.     Planned Merger with Colonial Gas Company

On October 17, 1998 Eastern signed a definitive  agreement that provides for the
merger of Colonial  Gas  Company  ("Colonial  Gas") into  Eastern for $37.50 per
share, payable in Eastern stock and $150 million in cash. The exchange ratio for
the stock  portion of the  consideration  will be based upon  Eastern's  average
closing stock price for a ten-day  period prior to closing,  subject to a collar
mechanism. The transaction is expected to close in mid-1999,  subject to receipt
of  satisfactory  regulatory  approvals and the approval of Eastern and Colonial
Gas  shareholders.  The merger is expected to be tax-free to the extent Colonial
Gas  shareholders  receive  Eastern  stock,  and will be accounted for using the
purchase method of accounting.


4.  Change in Accounting Principles

Effective  January 1, 1998,  Eastern adopted  Statement of Financial  Accounting
Standards No. 130,  "Reporting  Comprehensive  Income".  This statement requires
presentation of the components of comprehensive earnings,  including the changes
in equity from  non-owner  sources such as unrealized  gains on  securities  and
minimum pension liability  adjustments.  Eastern's total comprehensive  earnings
were are follows:

5.  Coal Miners Retiree Health Care

On June 25, 1998 the U.S.  Supreme  Court ruled that the Coal  Industry  Retiree
Health  Benefit Act of 1992 ("the Coal Act") is  unconstitutional  as applied to
Eastern.

Beginning in 1993,  Eastern recorded  provisions  totaling $80.0 million to fund
its liability under the Coal Act. As a result of the Supreme  Court's  decision,
Eastern reversed those  provisions,  less associated  expenses,  resulting in an
extraordinary gain of $74.5 million pretax, $48.4 million net or $2.13 per share
in the second quarter of 1998.

6.  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.

On September 29, 1998,  Midland  issued $75.0  million of 6.25% First  Preferred
Ship Mortgage Bonds maturing October 1, 2008. Proceeds of $68.5 million were net
of $6.0 million  incurred on treasury rate lock  agreements  entered into in the
second and third quarters in order to hedge the bond interest rate. The debt has
an effective annual interest rate of 7.50%.

The components of inventories were as follows:

Item 2.  Management's Discussion and Analysis of Financial Condition and
Results of Operations

RESULTS OF OPERATIONS

On September 30, 1998,  Eastern  completed the  acquisition  of Essex County Gas
Company  ("Essex Gas") by exchanging  2.0 million shares of Eastern common stock
for all of the common  stock of Essex Gas.  As  described  in Note 2 of Notes to
Financial  Statements,  the  transaction  was  accounted  for  as a  pooling  of
interests.  All  financial  statements  presented  for prior  periods  have been
restated to combine the financial information of Essex Gas and Boston Gas, which
are reported  below as Gas  operations.  Because Essex Gas has an August 31 year
end, Eastern's  consolidated  results include Essex Gas operations for the three
and nine month  periods  ended  August 31, 1998 and for the three and nine month
periods ended May 31, 1997.

Natural Gas Distribution

The decrease in gas revenues for the third  quarter of 1998  primarily  reflects
the inclusion in 1997 figures of a portion of Essex Gas heating season revenues.
Essex Gas revenues for the quarter ended May 31, 1997 were $11.1 million  higher
than for the quarter ended August 31, 1997.  This decrease was partially  offset
by pass through of higher gas costs at Boston Gas ($7 million).

Year-to-date  revenues  decreased due primarily to warmer weather ($26 million),
the migration of customers from firm sales to  transportation-only  service ($18
million) and the pass through of lower gas costs ($16 million), partially offset
by throughput  growth and higher  non-firm  sales.  Year-to-date  weather was 9%
warmer than normal,  compared to near normal weather in 1997. Essex Gas revenues
for the quarter  ended  November 30, 1997 were $4.4 million  higher than for the
quarter  ended  August 31,  1997,  which also  contributed  to the  year-to-date
decrease.


Marine Transportation

Overall weak  transportation  markets  experienced during the first half of 1998
generally continued into the third quarter,  reflecting the impact of the strong
U.S. dollar and Southeast Asia's economic problems on export demand for coal and


                                                                Form 10-Q

grain. Barge demand strengthened in the middle of the third quarter on increased
orders from  electric  utilities and  industrial  coal  customers,  coupled with
increased imports of steel-related products from the Gulf. Forecasts of a larger
grain  harvest  than  last year  helped  increase  spot  rates,  although  rates
generally remain below 1997 levels.  Lower fuel prices throughout 1998 decreased
rates  on  multi-year   contracts  containing  fuel  price  adjustment  clauses.
Production was disrupted by adverse operating conditions due to low water in the
Ohio Valley in September  and multiple  tropical  storms in the Gulf Coast areas
for  the  entire  quarter.  The low  water  caused  prolonged  lock  delays  and
groundings on Midland's main trade routes.

Tonnage  transported in the third quarter and year-to-date  increased 6% and 7%,
respectively, compared to the same periods in 1997 despite the adverse operating
conditions.  Third quarter ton miles were flat with 1997, while year-to-date ton
miles  were 3% below the prior  year  level.  The  tonnage  increases  primarily
reflect  replacement of reductions in long haul export tonnage with shorter haul
domestic movements. Coal tonnage shipped under multi-year contracts with utility
and industrial  customers increased 18% and 24%,  respectively,  for the quarter
and  year-to-date,  compared  to 1997.  Reduced  spot  domestic  and export coal
tonnage was partially offsetting.

Natural Gas Distribution

Operating  earnings for the third  quarter of 1998  decreased  by $2.8  million,
primarily  reflecting  the  inclusion in 1997 results of a portion of Essex Gas'
heating season earnings,  as discussed above.  Essex Gas operating  earnings for
the  quarter  ended May 31, 1997 were $2.3  million  higher than for its quarter
ended  August 31,  1997.  The  decrease  also  reflects  $0.8  million of merger
transaction costs expensed in 1998.



                                                                Form 10-Q
                                                                Page 12.




Year-to-date operating earnings increased by $3.3 million,  primarily reflecting
lower  operating  costs ($9 million),  growth in throughput  and higher  average
rates, partially offset by the margin impact of warmer weather ($8 million), the
absence of a pension  settlement  gain  reflected  in 1997 ($2 million) and $1.6
million of merger transaction costs.

The  pass   through   of  higher  or  lower   gas   costs   and   migration   to
transportation-only service have no impact on gas operating earnings.  Eastern's
natural  gas  distribution  operations  earn all of their  margins  on the local
distribution of gas and none on the resale of the commodity.


Marine Transportation

Operating earnings for the third quarter and year-to-date 1998 decreased by $1.6
million  and $2.3  million,  respectively,  reflecting  substantially  increased
operating expenses and weaker market conditions,  as described above. Additional
owned and  chartered  equipment  was  employed to help offset the impact of lock
delays in the Ohio Valley and weather delays in the Gulf.  The tropical  storms,
flooding and lock delays in the third quarter,  following the  disruptions  from
heavy rains associated with El Nino-related storms earlier in the year, resulted
in substantially  higher operating costs than 1997. Weak demand for export grain
and coal  throughout 1998 also increased  operating costs by disrupting  pattern
efficiencies.  These higher costs were partially offset by lower fuel prices, as
compared to 1997. New barge purchases increased depreciation expense and taxes.


Other Services

ServicEdge's  operating  losses of $2.8 million for the second  quarter and $7.5
million  for the first nine  months of 1998,  reflect  slower  than  anticipated
customer growth and general and administrative  expense associated with starting
this new business.


Other

Interest income and interest  expense for the third quarter of 1998 decreased by
$0.9 million and $1.5 million,  respectively,  primarily  reflecting  the use of
short-term  investments  to redeem $50 million of Midland debt in March 1998, as
discussed in Note 7. Year-to-date interest income and interest expense decreased
by $1.0  million  and  $3.3  million,  respectively,  primarily  reflecting  the
redemption of Midland debt.  Eastern  recognized an  extraordinary  loss of $2.3
million pretax, $1.5 million net, or $.06 per share on redeeming this debt.

In 1997,  other income  includes losses for the quarter and first nine months of
$2.2 million and $5.3 million,  respectively,  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 $3.0
million for the quarter and $4.6 million year-to-date.

In June 1998,  The U.S.  Supreme  Court held the Coal  Industry  Retiree  Health
Benefit of 1992 ("Coal Act") to be  unconstitutional,  as applied to Eastern. As
discussed  in  Note 5,  the  reversal  of Coal  Act  provisions  resulted  in an
extraordinary  gain of $74.5  million  pre-tax,  $48.4 million net, or $2.13 per
share in the second quarter of 1998.

In October 1998 Eastern  signed a definitive  agreement to acquire  Colonial Gas
Company  ("Colonial  Gas") for $37.50 in Eastern  stock and cash.  See Note 3 of
Notes.  The cash  consideration  has been  fixed at $150.0  million  and will be
financed by available funds.  Colonial Gas is a gas distribution utility serving
about 150,000 customers in and around Lowell, Massachusetts and on Cape Cod. The
merger is subject to a number of  conditions,  including  approval by regulators
and the shareholders of both Eastern and Colonial Gas.


YEAR 2000 ISSUES

State of Readiness

Eastern has assessed the impact of the year 2000 with respect to its information
technology  ("IT")  systems and embedded  chip systems as well as the  Company's
exposure to significant third party risks. In such regard, Eastern has initiated
and completed  substantial  portions of its plans to replace or modify  existing
systems and technology and to assure that major  customers and critical  vendors
are also  addressing  these  issues.  Year 2000  issues  for Essex Gas are being
addressed  by  integration  of its systems  with those of Boston  Gas,  which is
scheduled for completion by the first quarter of 1999.

With  respect to IT  systems,  Boston Gas has tested and  certified  four of its
eleven "mission critical"  application  systems. A fifth system is scheduled for
certification in the fourth quarter of 1998 and replacement of the remaining six
systems is in process and  scheduled to be  completed  by the second  quarter of
1999.  All other "less than  critical"  applications  are scheduled to be tested
and/or  upgraded  by the second quarter of 1999.  Conversion  and testing of all
mainframe hardware and software has been completed.  Replacements are in process
for client server,  data/voice  communications,  e-mail and desktop hardware and
software, with completion scheduled by the second quarter of 1999.

With respect to embedded chip systems, Boston Gas has completed an inventory and
expects to complete  its  assessment  and action  plan in the fourth  quarter of
1998. All remediation, conversion and testing is scheduled for completion by the
second quarter of 1999.

Boston Gas has  identified  material  third party  relationships  and expects to
complete  its detailed  survey and  assessment  of third party  readiness by the
fourth quarter of 1998.  Selected testing and  implementation of risk mitigation
strategies  for high risk vendors are  scheduled  for  completion  by the second
quarter of 1999.

Midland has modified and tested all mainframe-based  programs and systems, which
were  operating on a new mainframe as of September 30, 1998.  All  non-mainframe
(server)  based systems have been tested and all have been  modified  except for
Accounts Receivable,  which is scheduled for completion in the second quarter of
1999. Midland expects its personal computers to be 100% compliant by mid-1999.

With respect to embedded chip systems, Midland's major operating assets and
sub-systems were reviewed for embedded chip technology.  Based on this
review and actions taken, management believes year 2000 issues in regards to
internal chip technology will not impair its operating assets.

Midland  has  assessed  third  party risk with  respect to  critical  suppliers,
services and customers.  Midland is actively  seeking  written  confirmation  of
third party readiness.  If such readiness is in doubt, Midland expects to locate
backup providers by the second quarter of 1999.

Notwithstanding  Eastern's efforts with third parties, there can be no assurance
that the systems of third parties on which Eastern's systems rely will be timely
converted or that any such failure to convert by a third party would not have an
adverse effect on Eastern's operations.

Cost of year 2000 remediation

Boston Gas and Midland  expect the cost of their year 2000  compliance to
approximate  $13 million and $2 million, respectively, as detailed in the
following chart:


                                                                                              Expected future

Risks of year 2000 issues

Boston  Gas has  assessed  the most  reasonably  likely  worst  case  year  2000
scenario.  Given its  efforts to minimize  the risk of year 2000  failure by its
internal  systems  and its  distribution  network  control  systems,  Boston Gas
believes the worst case scenario  would occur if its primary  telecommunications
vendor  and/or its  electric  supplier  experiences  a year 2000  failure  which
results in an  outage.  An outage  would  require  Boston Gas to enact  disaster
recovery  measures to enable the continuation of service to its customers.  Such
measures would include  utilization of Boston Gas' co-generation  capability for
electrical power, relocating the customer inquiry function and use of a wireless
network for communications.

Midland  believes its worst case  scenario  would  involve  failures by the Army
Corps of  Engineers,  which  operates  the  various  lock and dam systems on the
inland  waterways,  or  by  rail  services  which  are  essential  for  bringing
commodities to the rivers for transit in Midland's barges.  These failures could
significantly   disrupt   Midland's   operations.   The  risk  of   failure   by
communications  systems or fuel  suppliers  is expected to be  mitigated  by the
availability of alternate suppliers.


Contingency plans

Boston Gas and Midland are in the process of  developing  contingency  plans and
anticipate having such plans in place by the second quarter of 1999.


                                    

                                                                Form 10-Q
                                                                Page 15.

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 the Colonial Gas merger
and  other  strategic  initiatives  on  earnings  and  cash  flow,  difficulties
encountered in integrating Eastern's gas utility operations,  temperatures above
or below normal in eastern Massachusetts, 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,  the  timetable  and cost for  completion  of
Eastern's  year 2000  plans,  the  impact of third  parties'  year 2000  issues,
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 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 environmental  liabilities,  normal debt
repayments,  anticipated  dividend  payments  to  shareholders  and the  planned
acquisition of Colonial Gas.

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

As discussed in Note 5, in March 1998, Midland utilized currently available cash
to redeem $50 million of 9.9% First Preferred Ship Mortgage Bonds,  due 2008. In
September 1998 Midland issued $75 million of 6.25% First Preferred Ship Mortgage
Bonds due October 1, 2008.  The $68.5  million net proceeds of the notes will be
used to fund  current  and  future  capital  expenditures  for  barges and other
capital equipment.

                                                 SIGNATURES


         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  other  than  changes   disclosed  in  Notes  to  Financial
Statements.  Such financial  information is subject to year-end  adjustments and
annual audit by independent public accountants.

         Pursuant to the  requirements  of the Securities  Exchange Act of 1934,
Eastern  has  duly  caused  this  report  to be  signed  on  its  behalf  by the
undersigned thereunto duly authorized.
