                      EASTERN ENTERPRISES AND SUBSIDIARIES
                          NOTES TO FINANCIAL STATEMENTS
                                  June 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

2.  Strategic Initiatives

Pending Merger with Colonial Gas Company

On July 15, 1999 the Massachusetts  Department of Telecommunications  and Energy
approved the merger of Colonial Gas Company ("Colonial Gas") into a wholly-owned
subsidiary  of Eastern  for $37.50 per share of Colonial  Gas stock,  payable in
Eastern  stock and $150.0  million in cash,  and the rate plan for  Colonial Gas
Company.  Pursuant  to the rate plan  approved in  conjunction  with the merger,
Colonial  Gas  customers  will receive a 2.2% price  reduction,  with base rates
frozen  for  ten  years.  The  exchange  ratio  for  the  stock  portion  of the
consideration  will be based upon Eastern's  average closing stock price for the
ten trading days period  prior to closing,  subject to a collar  mechanism.  The
transaction is expected to close on August 31, 1999, subject to receipt of final
regulatory  approval.  The merger is expected to be tax-free to Eastern and will
be accounted  for using the purchase  method of  accounting.  Under the purchase
method of accounting,  the operating results of Colonial Gas will be included in
Eastern's consolidated results for the periods subsequent to the closing.


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 early to 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.  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 six
month  periods  ended June 30, 1998 of Eastern  combined  with the three and six
month periods ended May 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 second  quarter of 1999 and the first
six months of 1999 were $171 million and $515  million, respectively, down 10%
and 5% from 1998.

Natural Gas Distribution

The natural gas  distribution  segment  includes  the  operations  of Boston Gas
Company and Essex 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  May 31 in the  prior  year at Essex Gas
reduced second quarter and year-to-date  comparative  revenues by $7 million and
$9 million, respectively.

Revenues for the second quarter of 1999 were $101.4 million, a decrease of $20.5
million or 17% from 1998.  The revenue  decrease  reflects  the pass  through of
lower  gas  costs ($7  million),  warmer  weather  ($3  million),  the Essex Gas
accounting  effects,  lower  weather-adjusted  average  usage and  migration  of
customers from firm sales to  transportation-only  service,  partially offset by
throughput growth.  Weather in the second quarter was 4% colder than normal, but
1% warmer than the previous year.

Year-to-date  1999 revenues were $381.7 million,  a decrease of $30.5 million or
7%. The decrease  reflects lower non-firm sales ($21 million),  the pass through
of lower gas costs ($9 million),  migration to  transportation  ($9 million) and
the Essex  Gas  accounting  effects,  partially  offset by the  impact of colder
weather ($19 million) and throughput growth.  Year-to-date weather was 3% warmer
than normal, but 7% colder than 1998.

Marine Transportation

Revenues for the second  quarter and first six months of 1999 were $65.8 million
and $127.1  million,  respectively,  showing  little  change  from  1998.  River
transportation  markets in the second quarter improved over the first quarter of
1999,  on  the  strength  of  increased   shipments  of  non-coal   commodities,
particularly grain. Continued weak demand for spot coal, reflecting high utility
inventories,  and export coal were partially offsetting.  Overall, rates per ton
mile  declined  5% for  the  quarter  and 4%  year-to-date,  due in  part to the
contractual pass through of lower fuel prices. As a result,  revenues  increased
1% for the second quarter but decreased 1% for the first six months, as compared
to 1998.

Tonnage  transported  increased 1% in the second quarter but declined 2% for the
first six months as  compared  to last year.  Coal  tonnage  declined 4% for the
second  quarter and 5% year to date.  Coal ton miles  increased 1% year to date,
reflecting  longer average hauls.  Non-coal tonnage  increased 8% and 4% for the
second quarter and year to date,  respectively,  reflecting  increased long haul
grain shipments.



                                                                Form 10-Q
                                                                Page 11.

Other Services

Revenues  for the second  quarter and first six months of 1999 were $3.4 million
and $6.6 million,  respectively,  up from $1.3 million and $1.4 million from the
comparable periods in 1998 primarily reflecting  increases at ServicEdge,  which
commenced operations in April 1998.


Operating Earnings:  Consolidated  operating earnings for the second quarter and
first six  months of 1999 were $1.7  million  and $59.6  million,  respectively,
reflecting decreases of 86% and 12% from the prior year.

Natural Gas Distribution

Natural gas  distribution  recorded  an  operating  loss of $1.9  million in the
second quarter of 1999. The $10.1 million decrease from 1998 reflects the effect
of the  accounting  treatment  used for revenue  recognition  and the use of the
fiscal  periods  ending  May  31 in the  prior  year,  including  merger-related
expenses,  at Essex  Gas ($4  million),  higher  operating  costs  ($4  million)
impacted by lower capitalized  expenses, a non-recurring  retiree benefit charge
and lower weather-adjusted average customer usage.

Operating  earnings  for the first six months of 1999 were $55.4  million,  down
$5.6 million or 9% from 1998. The decrease  reflects higher  operating costs ($8
million),  the Essex Gas accounting effects ($4 million) and lower average usage
($2 million).  Partially offsetting were the margin impact of colder weather ($6
million) and growth in throughput ($3 million).

The  pass   through   of  higher  or  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 second quarter of 1999 were $5.8 million, a decrease
of $2.0 million from 1998.  Operating  earnings for the first six months of 1999
were $8.9 million,  down $4.9 million from the prior year. The decreases for the
second quarter and year-to-date  reflect lower rates and higher costs associated
with crew labor,  port expenses,  vessel  maintenance  and insurance.  Partially
offsetting  were improved  operating  conditions  during the second  quarter and
lower fuel costs year to date.


Other Services

Other Services'  operating losses for the second quarter and first six months of
1999 were $1.2 million and $2.5 million,  respectively, as compared to losses of
$2.6  million and $4.8  million  during the  comparable  periods in 1998.  These
losses  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

Other:

Net  interest  expense  for the  second  quarter  and first  six  months of 1999
decreased by $0.2 million and $0.4 million,  primarily  reflecting lower working
capital  requirements  for  natural  gas  distribution.   The  reduced  interest
associated  with the issuance of $75.0  million of 6.25%  (effective  rate 7.5%)
debt by Midland in September 1998,  which replaced $50.0 million of 9.9% Midland
debt  redeemed in March 1998,  was largely  offset by the  combination  of lower
average investment balances and interest rates.

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,  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 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.

With respect to IT systems, natural gas distribution has tested and certified as
year 2000 ready all eleven "mission critical" business systems.  Installation of
an upgrade  and  replacement  to two of these  systems  scheduled  for the third
quarter of 1999 will include  year 2000  re-certification  testing.  Half of the
less than critical business systems have completed  certification  testing while
the  balance is  scheduled  for  testing  during the third  quarter of 1999.  An
integration test plan designed to re-certify interfaces between mission critical
systems has been  developed  and is  scheduled  for  execution  during the third
quarter  of  1999.  Conversion  and  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  telephony
components  have been  certified  as year 2000  ready with the  exception  of an
upgrade to a call  management  server that is scheduled  for the third  quarter.
Eighty percent of the company's desktop hardware,  operating system software and
applications have been certified as year 2000 ready with the remaining  desktops
scheduled to be certified as part of the rollout of an upgraded  application  in
the third  quarter of 1999.  To minimize the risk of  corruption  of  previously
certified  information  systems, the Company plans to impose a freeze on changes
to information systems and technology components, effective October 1, 1999 With
respect to embedded chip systems, the Company


                                                                Form 10-Q
                                                                Page 13.

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 begun  testing  electronic
interfaces with suppliers,  where  practicable,  and 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  programs and
systems,  which are operating on a year 2000 compliant mainframe.  Substantially
all client server and desktop-based systems have been tested and modified except
for the accounts receivable system, which is scheduled for production rollout by
September 30, 1999.

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.

Cost of year 2000 remediation

Natural gas distribution  and marine  transportation  expect the cost of year
2000 compliance to approximate  $16.2 million as detailed in the following
chart:



                                                                Cost through June         Expected

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  failures that impact data and
voice communication  providers, 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 planning process.


                                                                Form 10-Q

Marine   transportation   believes  its  worst  case   scenario   would  involve
infrastructure  disruption through failure of third party services.  These could
include, without limit: lock and dam operations,  rail services for river-served
docks and terminals, 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 initiated the development of a business contingency
plan  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.  Draft plans have been  developed and tested
for each of these  major  risk  areas.  During the third  quarter  of 1999,  the
Company expects to finalize and test these plans via live drills.

Marine  transportation has substantially  completed preparation of a contingency
plan,  which it expects to complete by September  30, 1999. To the extent marine
transportation  believes that any supplier of critical goods or services poses a
significant risk of year 2000 failure,  it expects to locate backup providers by
September 30, 1999.

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.

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
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,  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 acquisitions of Colonial Gas and EnergyNorth.

Consolidated  capital  expenditures are budgeted at  approximately  $85 million,
with about 75% at natural  gas  distribution  segment  and the balance at marine
transportation.  In addition,  marine  transportation  to enter into a series of
long-term  operating leases for up to 100 additional new barges in the third and
fourth quarters of 1999, the terms of which are still under  negotiation  with a
selected financial institution.
