                         NOTES TO FINANCIAL STATEMENTS
                               September 30, 1999


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.  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 1998 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:

In 1998, a capital loss carryforward eliminated the need for an income tax
provision associated with capital gains.


2.  Planned Merger with EnergyNorth, Inc.

On July 14, 1999, Eastern signed a definitive agreement that provides for the
merger of EnergyNorth, Inc. ("EnergyNorth") into a wholly-owned  subsidiary of
Eastern at a value of $47.00 per share of  EnergyNorth.  Under the agreement,
50.1% of the common stock of EnergyNorth  will be  converted  into  Eastern
stock and the balance will be  converted  into cash.  The exchange  ratio for
the stock portion of the consideration  will be based upon Eastern's  weighted
average trading stock price for a ten-day period prior to closing, subject to a
collar mechanism.  The transaction is expected to close in mid-2000, subject to
receipt of  satisfactory  regulatory approvals and the approval of EnergyNorth
shareholders.  The merger is expected to be tax-free to Eastern and, as with
the Colonial transaction, will be accounted for using the purchase method of
accounting.


3.  Mergers

Colonial Gas Merger

On August 31, 1999,  Eastern  completed a merger with Colonial Gas in a
transaction  with an enterprise  value of  approximately  $474 million.  In
effecting  the  transaction,  Eastern paid $150 million in cash,  net of cash
acquired and  including  transaction  costs, issued approximately  4.2 million
shares of common stock valued at $186 million and assumed $138 million of debt.
The cash portion of the transaction was financed through available cash and
borrowings under Eastern's line of credit.

The Colonial  merger has been  accounted  for using the purchase  method of
accounting  for business  combinations.  Accordingly,  the accompanying
Consolidated  Statements of Operations include Colonial Gas' results commencing
August 31, 1999. The purchase price was allocated to the net assets  acquired
based on their fair value.  The historical  cost basis of Colonial Gas' assets
and  liabilities, with the exception of its retiree benefit obligations and the
adjustments  described below, was determined to represent the fair value due to
the existence of a  regulatory-approved  rate plan based upon the recovery of
historical  costs and a fair return thereon.  As a result of the merger and
related rate plan,  value was not allocated to systems that will no longer be
used due to the  integration  of Colonial into Eastern's  natural gas

                                                                 Form 10-Q
                                                                    Page 8
distribution  business and value was not allocated to Colonial's net regulatory
assets.  No value was allocated to the net regulatory assets because the rate
plan does not meet the criteria for the continued  application of SFAS 71,
Accounting for the Effects of Certain Types of Regulation.  The  allocation of
the purchase  price remains  subject to adjustment upon final valuation of
certain acquired balances.  The excess of cost over the fair value of the net
assets acquired,  or goodwill, of $248 million has been recorded as an asset
and is being amortized on a straight-line basis, principally over a period of
40 years.

The following table sets forth the Company's unaudited pro forma results as if
the transaction had occurred on January 1, 1998.

only and include  certain  adjustments  which primarily reflect goodwill
amortization, reduced interest income and an adjusted income tax provision
using Eastern's incremental rate of 35%.

Essex Gas Merger

On  September  30,  1998,  Eastern  completed  a merger  with  Essex Gas which
was accounted for as a pooling of interests and the accompanying consolidated
financial  statements  include the accounts of Essex Gas for all periods.
Prior to the merger,  Essex Gas' fiscal year ended on August 31. Accordingly,
the accompanying consolidated  statement of operations for the current period
reflects a calendar  alignment of periods for Eastern and Essex Gas,  while the
prior period  comparative  statement  of  operations  reflects the three and
nine month periods ended  September 30, 1998 of Eastern  combined with the
three and nine month periods ended August 31, 1998 of Essex Gas.

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

RESULTS OF OPERATIONS

Revenues:  Consolidated  revenues for the third quarter of 1999 were $145
million,  up 7% from 1998. Revenues for the first nine months of 1999 were
$660 million, down 2% from the prior year.


Natural Gas Distribution

The natural gas  distribution  segment  includes the operations of Boston Gas
Company,  Essex Gas Company and Colonial Gas Company, as discussed in Note 3
of Notes to Financial  Statements.  The effect of the accounting treatment used
for revenue recognition and the use of fiscal  periods ending August 31 in the
prior year at Essex Gas reduced  year-to-date  comparative  revenues by $9
million,  but did not  significantly impact comparative revenues for the
quarter.  Revenues for the quarter and  year-to-date  include  Colonial Gas
revenues of $4.4 million since the August 31, 1999 date of acquisition.

Revenues for the third quarter of 1999 were $70.8 million,  an increase of
$3.4 million or 5% from 1998. The revenue increase  reflects the addition of
Colonial Gas revenues, partially offset by the pass through of lower gas costs.

Year-to-date revenues were $452.4 million, a decrease of $27.1 million or 6%.
The decrease reflects lower non-firm  sales ($19 million), the pass through
of lower gas costs ($11 million), migration to transportation ($10 million)and
the Essex Gas accounting effects, partially offset by the impact of colder
weather ($17 million), throughput growth and the additional Colonial Gas
revenues.


Marine Transportation

Revenues  for the third  quarter of 1999 were $69.7  million,  up $2.8 million
or 4% from  1998.  For the first nine  months of 1999, revenues were
$196.8 million,  up $2.1 million or 1% from the prior year.  These increases
reflected a strong market for grain exports and  increased import activity of
ores and  steel-related  raw  materials,  partially  offset by declines in coal
demand by electric utilities, as high stockpiles slowed shipments.  Rates per
ton mile in the quarter  improved  modestly over the same period in 1998,
primarily  due to the  strengthening  of the grain and  import  markets
discussed  above,  while  rates for spot coal  movements  were generally lower.
Rates also benefited from contractual pass through  provisions in multi-year
contracts  related to fuel prices that were up 22% from 1998 for the quarter,
but down 2% for the first nine months.

Tonnage  transported  decreased  2% for both the third  quarter and first nine
months as  compared to last year.  Coal  tonnage for the third quarter and
year-to-date  declined 9% and 7%,  respectively.  Coal ton miles were down 10%
for the quarter and 3%  year-to-date, mainly from continued weak demand for
spot and export  movements.  Non-coal  tonnage  increased  11% and 6% for the
third quarter and year-to-date, respectively, as a result of the market factors
discussed above.  Non-coal ton miles increased 13% and 8% for the third quarter
and year-to-date periods.


                                                                 Form 10-Q
                                                                   Page 12

Other Services

Revenues for the third quarter and first nine months of 1999 were $4.5 million
and $11.1  million,  respectively,  up from $1.7 million and $3.0 million for
the comparable periods in 1998, primarily reflecting increases at ServicEdge,
which  commenced  operations in April 1998.


Operating  Earnings:  Consolidated operating earnings for the third quarter of
1999 were a seasonal loss of $4.8 million,  as compared to a loss of
$4.5 million for 1998.  Consolidated  operating  earnings for the first nine
months of 1999 were $54.8 million, down $8.1 million or 13% from the prior year.


Natural Gas Distribution

Natural gas distribution recorded an operating  loss of $9.4  million for the
third  quarter of 1999,  as compared to a loss of $7.6 million for the prior
year. The $1.8 million  decrease from 1998 reflects the inclusion of Colonial
Gas' $1.0 million  post-acquisition operating  loss,  higher  operating  costs
including a $2.2 million  charge for an early  retirement  program at Boston
Gas related to integration  of Colonial Gas  operations,  partially  offset by
lower  expenses,  principally  bad debt  expense,  reflecting  improved
collections experience.

Operating  earnings for the first nine months of 1999 were $45.9  million, down
$7.4 million or 14% from 1998.  The decrease  reflects higher  operating costs
($10 million),  the effect of the  accounting  treatment  used for revenue
recognition  and the use of fiscal periods  ending  August 31 in the prior year
($4 million),  Colonial  Gas'  post-acquisition  operating  loss and lower
average  usage.  Partially  offsetting  were the margin  impact of 7% colder
weather ($6 million) and growth in throughput  ($3 million).  Year-to-date
weather was 3% warmer than normal compared to the 10% warmer than normal
weather in 1998.

The pass through of lower gas costs and migration to  transportation-only
service have no impact on the segment's  operating earnings.  Natural gas
distribution earns all of its margins on the local distribution of gas and none
on the resale of the commodity.

Marine Transportation

Operating earnings for the third quarter of 1999 were $6.7 million, a decrease
of $1.7 million or 20% from 1999.  Operating earnings for the first nine months
of 1999 were $15.6  million,  down $6.6  million or 30% from the prior  year.
The  decreases  for the third quarter and year-to-date reflect higher costs
associated with crew labor,  port expenses,  vessel  maintenance and insurance.
Drought conditions impacted operations on the lower Mississippi River during
the third quarter.

Other Services

Other services'  operating losses for the third quarter and fist nine months of
1999 were $1.2 million and $3.7 million, respectively, as compared to losses of
$3.0  million and $7.8  million  for the  comparable  periods in 1998.  These
losses  primarily  reflect the operations of  ServicEdge.  Lower  operating
losses in 1999  primarily  reflect a reduction in costs  associated  with the
start-up of ServicEdge.

                                                                 Form 10-Q
                                                                   Page 13

Other

The $2.1 million  reduction in the  Headquarters  operating loss for the third
quarter of 1999 primarily  reflects the absence of legal and consulting
expenses associated with the Essex acquisition in 1998.

Net interest  expense for the third  quarter and first nine months of 1999
increased  by $1.0  million and $.6 million,  respectively, primarily
reflecting the cash paid for the Colonial Gas acquisition  and the issuance of
debt by Midland in September 1998,  partially offset by interest income on a
tax settlement and lower working capital  requirements  for natural gas
distribution  during the first part of 1999. The reduced interest expense
associated with the Midland's  issuance of $75 million of 6.25% (effective
rate 7.5%) debt, which  replaced  $50.0  million of 9.9% Midland debt redeemed
in March 1998,  was largely  offset by a  combination  of lower  interest
income due to reduced average investment balances and interest rates.

Other,  net for the third  quarter of 1999  includes a $3.2  million  reduction
in the  environmental  reserve  reflecting  regulatory clearance of one site,
$2.5 million in environmental-related insurance recoveries and a $1.8 million
gain on the sale of a towboat.  Other, net in 1998 primarily reflects realized
gains on investments of $2.9 million for the quarter and $4.5 million
year-to-date.

In the first quarter of 1998,  Eastern  recognized an extraordinary loss of
$2.3 million pretax,  $1.5 million net, or $.06 per share, on redeeming the
Midland debt noted above.

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

Net earnings for the first quarter of 1998 include $8.2 million, or $.36 per
share, for the cumulative  effect of changing Boston Gas' method of accounting
for unbilled revenues to an accrual method.


YEAR 2000 ISSUES

State of Readiness

Eastern has assessed the impact of the year 2000 with respect to its information
technology  ("IT") and embedded chip systems as well as the Company's exposure
to significant  third party risks. In such regard,  Eastern has completed the
replacement or modification of existing  systems and technology as required and
has taken  reasonable steps to assure itself that major customers and critical
vendors are also addressing these issues.  In addition,  Eastern has completed
the development and testing of its contingency  plans to address major external
and internal risks that could potentially impact business operations.


                                                                 Form 10-Q
                                                                   Page 14

With  respect to IT  systems,  natural gas  distribution  has tested and
certified  as year 2000 ready all eleven  "mission  critical" business systems
and all eighteen less than critical  business  systems.  Recertification  of
mission critical systems and integration points has been completed. Conversion
and  certification  testing of all  technology  infrastructure  components has
been  completed, including mainframe and client server hardware and software,
data/voice  communications and e-mail systems.  All telephone  components
have been certified as year 2000 ready. All of the Company's desktop hardware,
operating system software and applications  have been certified as year 2000
ready. To minimize the risk of corruption of previously  certified information
systems,  the Company imposed a freeze on changes to information systems and
technology  components,  effective in early October 1999. The Company  expects
changes to its production  environment to be governed by strict change
management  procedures and to be limited to emergency  production fixes and
regulatory-required changes.

With respect to embedded chip systems, the Company has completed its inventory,
assessment,  remediation and certification  testing of all date sensitive
components containing embedded chips and is year 2000 ready.

Natural gas  distribution  has identified  material  third party  relationships
and has completed a detailed  survey and assessment of third party  readiness.
A readiness  assessment  has been completed of all mission critical suppliers
and risk  mitigation plans developed.  The Company has implemented risk
mitigation  strategies as required.  However,  there can be no assurance that
third party systems,  on which the Company'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 the Company's operations.

Marine  transportation has modified and tested all  mainframe-based "mission
critical" programs and systems,  which are operating on a year 2000 compliant
mainframe.  Client server and desktop-based  systems have also been modified
and tested.  Data/voice  communication and e-mail systems have been tested and
replaced where necessary.

With respect to embedded chip systems,  marine  transportation has reviewed its
major operating assets and their sub-systems.  Based on this review and actions
taken,  management  believes its  operations  will not be impaired by year 2000
issues with regard to embedded chip technology.

Marine  transportation  has assessed  third party risk with respect to
significant  suppliers,  services and customers and is actively seeking written
confirmation  of third party  readiness.  While many third parties express
confidence in their year 2000 programs and project completion by mid-1999, they
do not make 100% guarantees or assurances.

                                                                 Form 10-Q

Cost of year 2000 remediation

Natural gas distribution  and marine  transportation  expect the cost of year
2000 compliance to approximate $16.8 million as detailed in the following chart:

Risks of year 2000 issues

Natural gas distribution and marine transportation operations have 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  system, natural gas
distribution  believes its worst case scenario would involve third party
failures that impact data and voice  communicationproviders,  its electricity
provider or a pipeline supplier.  Scenarios involving one or more of these
failures are addressed in detail as part of the Company's business contingency
plans.

Similarly,  marine  transportation  believes  its worst case  scenario  would
involve  third party  failures  that impact lock and dam operations, rail
services for river-served docks and terminals, or telecommunications,
electricity and banking services. Major delays to river traffic and customers
could result in a loss of revenues.  Such failures would require the Company to
enact disaster  recovery plans, use alternate service providers and seek other
routes of navigation, to the extent possible.

Contingency plans

Natural gas distribution has completed the development of business contingency
plans  concerning  year 2000 risks to its internal systems, embedded chips and
significant  suppliers.  An impact  analysis of business  processes has been
completed  which  identified voice/data  communications, electricity  and gas
supply as the three major  sources of risk.  Plans have been  developed  and
desk top tests  conducted  for each risk area.  Live drills were successfully
conducted  to test the  Company's  ability to deliver  critical services in the
event of a failure or disruption in voice/data communications.

Marine  transportation  has completed  preparation of a contingency  plan,
based on an assessment of third party risk. The Company has obtained  written
and verbal  confirmation  from providers of critical  services as to their year
2000 readiness.  To the extent marine transportation believes that any supplier
of critical  goods or services  poses a significant  risk of year 2000 failure,
the Company has located or identified backup providers.

Eastern  believes its actions and planning  efforts are appropriate to address
year 2000 concerns.  However,  Eastern cannot  guarantee that such actions will
prevent all or any year 2000  disruptions to itself,  its customers or its
suppliers.  The Company cautions that forward  looking  statements  contained
in the year  2000  discussion  should be read in  conjunction  with the
following  disclosure statement regarding such information.



                                                                 Form 10-Q
                                                                   Page 16

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  forward-looking  projections or expectations.  These
factors  include,  but are not limited to: the effect of pending  mergers and
other  strategic  initiatives on earnings and cash flow, Eastern's ability to
successfully  integrate its new gas distribution  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 ultimate profitability of
ServicEdge,  the functionality of programs and systems in the year 2000, 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,  is more than sufficient to meet
Eastern's 1999 capital expenditure  requirements,  potential funding of its
environmental  liabilities,  normal debt repayments, anticipated dividends to
shareholders and the planned acquisition of EnergyNorth.

Consolidated  capital  expenditures are budgeted at approximately $85 million,
with about 80% at natural gas distribution  segment and the balance at marine
transportation.  In addition,  marine transportation has signed a series of
long-term operating leases for up to 100 additional new barges for delivery by
year end.

On August 16, 1999,  Eastern announced 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.

         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.
