ITEM 1. BUSINESS.
 
GENERAL
 
  Boston Gas Company (the "Company"), is engaged in the transportation and
sale of natural gas to approximately 530,000 residential, commercial and
industrial customers in Boston, Massachusetts and 73 other communities in
eastern and central Massachusetts. The Company also sells gas for resale. The
Company has one subsidiary, Massachusetts LNG Incorporated ("Mass LNG"), which
held a long-term lease on two liquefied natural gas ("LNG") facilities and now
operates the facilities pursuant to an agreement (see Item 2, Properties). The
Company is the largest natural gas distribution company in New England, has
been in business for 175 years and is the second oldest gas company in the
United States. All of the common stock of the Company is held by Eastern
Enterprises ("Eastern"), which is headquartered in Weston, Massachusetts.
Eastern has owned Boston Gas Company since 1929.
 
  For definition of certain industry specific terms, see the Glossary at the
end of Part I and appearing on page 6.
 
  The Company provides both local transportation services and gas supply for
all customer classes. All residential customers currently purchase combined or
"bundled" supply and transportation services from the Company. In 1993, the
Massachusetts Department of Telecommunications and Energy, formerly the
Department of Public Utilities ("the Department") approved the Company's
proposal to unbundle local transportation service and gas sales service for
its 450 largest commercial and industrial customers. In November 1996, the
Department approved the Company's proposal to offer unbundled transportation
service to all of its commercial and industrial customers, numbering over
41,000. As of December 31, 1997, 2,174 customers have chosen to purchase gas
from 22 qualified third party suppliers. The Company views these third party
suppliers as trade allies in marketing gas and increasing its throughput and
expects to work closely with them to facilitate the unbundling process and
ensure a smooth transition, especially in the tracking and processing of
transactions. While the migration of customers from firm sales to
transportation-only service will lower the Company's revenues, it has no
impact on the Company's operating earnings. The Company earns all of its
margins on the local distribution of gas and none on the resale of the
commodity itself. The Company has implemented a program to educate commercial
and industrial customers about the opportunity to purchase gas from third-
party suppliers, while still relying on the Company for delivery.
 
  The Company offers both firm and non-firm services. Firm local
transportation services and sales are provided under rate tariffs or contracts
filed with the Department that typically obligate the Company to provide
service without interruption throughout the year. Non-firm transportation
services and sales are generally provided to large commercial and industrial
customers who can use gas and oil interchangeably. Non-firm services,
including sales to other gas companies for resale, are provided through
individually negotiated contracts and, in most cases, the price charged takes
into account the price of the customer's alternative fuel.
 
  In the fourth quarter of 1997, the Company recorded $8.7 million of
restructuring charges in connection with its decision to exit the gas
appliance repair and service business. This will allow the Company to focus on
its core business of local transportation and expanding throughput on its
system.
 
MARKETS AND COMPETITION
 
  The Company competes with other fuel distributors, primarily oil dealers,
throughout its service territory. Over the last six years, the Company has
increased its share in the total stationary energy market from 31% to 37%.
This market share compares to the national level of approximately 44%, and may
represent a growth opportunity for the Company. However, actual experience
cannot be predicted with certainty, and will depend on such factors as the
price of competitive energy sources, the level of investment by the Company
and customer perceptions of relative value.

  Residential customers comprise 92% of its customer base, while commercial
and industrial establishments account for the remaining 8%. Volumetrically,
residential customers account for 26% of total throughput and 35% of total
firm throughput, while commercial and industrial customers account for 74% of
total throughput and 65% of total firm throughput. In 1997, approximately 70%
of commercial and industrial customers' total throughput was local
transportation-only services; Boston Edison Company, an electric utility on
the Company's system, accounted for approximately 44% of the commercial and
industrial local transportation throughput.
 
  No customer, or group of customers under common control, accounted for 2% or
more of total firm revenues in 1997.
 
GAS SUPPLY

</TABLE>
 
  Year to year variations in storage gas and unbilled gas reflect variations
in end-of-year customer requirements, due principally to weather. Given the
ready availability of supply, the Company purchased approximately two-thirds
of its peak pipeline supplies under firm short-term and spot contracts. The
balance of peak day pipeline requirements is purchased directly from domestic
and Canadian producers and marketers pursuant to long-term contracts which
have been reviewed and approved by the Department or by the Federal Energy
Regulatory Commission ("FERC").
 
  Pipeline supplies are transported on interstate pipeline systems to the
Company's service territory pursuant to long-term contracts. FERC-approved
tariffs provide for fixed demand charges for the firm capacity rights

</TABLE>
 
  In addition, the Company has firm capacity contracts on interstate pipelines
upstream of Algonquin and Tennessee pipelines to transport natural gas
purchased by the Company from producing regions to the Algonquin and Tennessee
pipelines. In total, contracts comprising 59% of the Company's peak day
pipeline capacity entitlements expire before 2001.
 
  The Company has contracted with pipeline companies and others for the
storage of natural gas in underground storage fields located in Pennsylvania,
New York, Maryland and West Virginia. These contracts provide storage capacity
of 17.3 BCF and peak day deliverability of 0.16 BCF. The Company utilizes its
existing transportation contracts to transport gas from the storage fields to
its service territory. Supplemental supplies of LNG and propane are purchased
and produced from foreign and domestic sources.
 
  Peak day throughput in BCF was 0.66 in 1997 and 0.69 in 1996 and 1995. The
Company provides for peak period demand through a least cost portfolio of
pipeline, storage and supplemental supplies. The Company considers its peak
day send out capacity, based on its total supply resources, to be adequate to
meet the requirements of its firm customers.
 
REGULATION
 
  The Company's operations are subject to Massachusetts statutes applicable to
gas utilities. Rates, gas purchases, pipeline safety regulations, issuance of
securities, and affiliate transactions are regulated by the Department. Rates
for firm transportation and sales provided by the Company are subject to
approval by, and are on file with, the Department. In addition, the Company
has a cost of gas adjustment clause that allows for the adjustment of billing
rates for firm gas sales to enable it to recover the actual cost of gas
delivered to firm customers, including the demand charges for capacity on the
interstate pipeline system.
 
  On May 16, 1997 the Company received a response from the Department
concerning its request for reconsideration, clarification and recalculation of
the Department's November 1996 rate order. The Department granted an
additional $1.9 million in revenues (a $6.3 million increase was granted in
the November 1996 Order) and reduced the productivity offset portion of the
Performance-Based Rate ("PBR") formula established in its November 1996 Order
by 50 basis points, from 2.00% to 1.50%. Compared to the Department's original
decision these changes will add approximately $3.5 million to projected
revenue in 1998, increasing to about $8.0 million by 2002, the last year of
the plan. The Department also made modifications to the service quality
measures requested by the Company, but left unchanged the Company's maximum
annual exposure of $5.0 million for failing to achieve them. On June 5, 1997,
the Company filed a notice of appeal of the Department's orders to the
Massachusetts Supreme Judicial Court. The Company expects that the appeal will
take approximately one year, and that any relief granted by the court will be
prospective.
 
  On July 18, 1997, the Department directed all ten investor-owned gas
distribution companies in Massachusetts to undertake a collaborative process
with other stakeholders to develop common principles under which comprehensive
gas service unbundling might proceed. The Department deferred the second phase
of the Company's unbundling proceeding, which is to address residential
unbundling and a permanent capacity assignment method, subject to its
assessment of the progress of the collaborative discussions.
 
                                       3
<PAGE>
 
  On November 7, 1997, the Department approved rate schedules designed to
implement the Company's $1.8 million rate increase approved by the Department
in the Company's first annual performance-based regulatory plan compliance
proceeding.
 
  In its November 1996 order, the Department also approved the Company's
proposal to facilitate competition in the natural gas marketplace. Under the
approved service unbundling program, on an interim basis, eligible commercial
and industrial customers migrating from firm sales to firm transportation will
be assigned, at cost, a pro-rata share of the upstream pipeline capacity
purchased by the Company to serve them. At the Department's direction,
permanent assignment of upstream pipeline capacity is currently being
addressed as part of the collaborative process discussed above. The capacity
assignment method ultimately approved by the Department could permit capacity
to be acquired by marketers at less than cost. If that proves to be the case,
there can be no assurance that the Company will be permitted to recover such
costs until the Department has addressed their recoverability. The
collaborative is also examining how to extend unbundled transportation service
to residential customers.
 
  The Company and Eastern were granted an intrastate exemption from the
provisions of the Public Utility Holding Company Act of 1935 ("the Act") under
Section 3(a)(1) thereof, pursuant to an order of the Securities and Exchange
Commission (the "SEC") dated February 28, 1955, as amended by orders dated
November 3, 1967 and August 28, 1975.
 
SEASONALITY AND WORKING CAPITAL
 
  The Company's revenues, earnings and cash flow are highly seasonal as most
of its transportation services and sales are directly related to temperature
conditions. The majority of the Company's earnings are generated in the first
quarter with a seasonal loss occurring in the third quarter. Since the
majority of its revenues are billed in the November through April heating
season, significant cash flows are generated from late winter to early summer.
In addition, through the cost of gas adjustment clause, the Company bills its
customers over the heating season for the majority of the pipeline demand
charges paid by the Company over the entire year. This difference, along with
other costs of gas distributed but unbilled, is reflected as deferred gas
costs and is financed through short-term borrowings. Short-term borrowings are
also required from time to time to finance normal business operations. As a
result of these factors, short-term borrowings are generally highest during
the late fall and early winter.
 
ENVIRONMENTAL MATTERS
 
  The Company may have or share responsibility under applicable environmental
law for the remediation of former manufactured gas plant ("MGP") sites.
Information with respect to the remediation of MGP sites may be found in Note
12 of Notes to Consolidated Financial Statements. Such information is
incorporated herein by reference.
 
EMPLOYEES
 
  As of December 31, 1997, the Company had approximately 1,440 employees, 74%
of whom are organized in local unions with which the Company has collective
bargaining agreements that expire in 1999.
 
ITEM 2. PROPERTIES.
 
  The Company and Mass LNG operate facilities which enable them to liquefy
natural gas in periods of low demand, store the resulting LNG and vaporize it
for use in periods of high demand. The Company owns and operates such a
facility in Dorchester, Massachusetts. Mass LNG leased one such facility
located in Lynn, Massachusetts and a storage facility in Salem, Massachusetts
under a lease that expired on June 30, 1997. Negotiations for the purchase of
the facilities stalled and the matter is now in litigation (see Item 3, Legal
Proceedings). Mass LNG continues to operate the facilities pursuant to a
stipulation and agreement between the
 
                                       4
<PAGE>
 
parties that provides for $2.3 million to be held in escrow and suspends Mass
LNG's rent payment obligation while the stipulation and agreement is in
effect. The stipulation and agreement terminates on the earlier of the
resolution by judgment or October 1, 1998.
 
  The Company owns propane-air facilities at several locations throughout its
service territory.
 
  On December 31, 1997, the Company's distribution system included
approximately 5,800 miles of gas mains, 401,000 services and 534,000 active
customer meters. A majority of the gas mains consist of cast iron and bare
steel, which require ongoing maintenance and replacement.
 
  The Company's gas mains and services are usually located on public ways or
private property not owned by it. In general, the Company's occupation of such
property is pursuant to easements, licenses, permits or grants of location.
Except as stated above, the principal items of property of the Company are
owned in fee.
 
  In 1997, the Company's capital expenditures were $55.4 million. Capital
expenditures were principally made for improvements to the distribution
system, for system expansion to meet customer demand and for productivity
improvements. The Company plans to spend approximately $59 million for similar
purposes in 1998.
 
ITEM 3. LEGAL PROCEEDINGS.
 
  On May 6, 1997, Mass LNG filed suit against the Industrial National Leasing
Corp. ("INLC") in Suffolk Superior Court, Massachusetts. This action results
from the parties' being unable to reach agreement relative to Mass LNG's
purchase rights set forth in the lease agreement under which Mass LNG leased
two LNG facilities from INLC (see Item 2, Properties). The complaint seeks a
judicial determination of the parties' rights under the lease.
 
  Other than the Mass LNG litigation and routine litigation incidental to the
Company's business, there are no material pending legal proceedings involving
the Company.
 
ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.
 
  No matter was submitted to a vote of Security Holders in the fourth quarter
of 1997.

                                   GLOSSARY
 
  BUNDLED SERVICE--Two or more services tied together as a single product.
Services include gas sales at the city gate, interstate transportation, local
transportation, balancing daily swings in customer loads, storage, and peak-
shaving services.
 
  CAPACITY--The capability of pipelines and supplemental facilities to deliver
and/or store gas.
 
  CITY GATE--Physical interconnection between an interstate pipeline and the
local distribution company.
 
  CORE CUSTOMER--Generally, customers with no readily available energy
services alternative.
 
  FIRM SERVICE--Sales and/or transportation service provided without
interruption throughout the year. Uninterrupted seasonal services are also
available for less than 365 days. Firm services are provided under either
filed rate tariffs or through individually negotiated contracts.
 
  GAS MARKETER (BROKER)--A non-regulated buyer and seller of gas.
 
  INTERSTATE TRANSPORTATION--Transportation of gas by an interstate pipeline
to the city gate.
 
  LOCAL DISTRIBUTION COMPANY (LDC)--A utility that owns and operates a gas
distribution system for the delivery of gas supplies from the city gate to
end-user facilities.
 
  LOCAL TRANSPORTATION SERVICE--Transportation of gas by the LDC from the city
gate to the customer's burner tip.
 
  NON-CORE CUSTOMERS--Generally, those customers with readily available,
economically viable alternatives to gas.
 
  NON-FIRM SERVICE--Sales and transportation service offered at a lower level
of reliability and cost. Under this service, the LDC can interrupt customers
on short notice, typically during the winter season. Non-firm services are
provided through individually negotiated contracts and, in most cases, the
price charged takes into account the price of the customer's energy
alternative.
 
  PERFORMANCE-BASED REGULATORY PLAN--Incentive ratemaking mechanism, typically
a price cap plan, where rates are adjusted annually pursuant to a pre-
determined formula tied to a measure of inflation, less a productivity offset,
subject to the achievement of service quality measures and the incurrence of
exogenous costs.
 
  THROUGHPUT--Gas volume delivered to customers through the LDC's gas
distribution system.
 
  UNBUNDLED SERVICE--Service that is offered and priced separately, such as
separating the cost of gas commodity delivered to the LDC's city gate from the
cost of transporting the gas from the city gate to the end user. Unbundled
services can also include daily or monthly balancing, back-up or stand-by
services and pooling. With unbundled services, customers have the opportunity
to select only the services they desire.

ITEM 5. MARKET FOR THE REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER
MATTERS.
 
  Eastern was the holder of record of all of the outstanding common equity
securities of the Company throughout the year ended December 31, 1997.
Dividends on such common equity amounted to $18.3 million and $14.7 million
for 1997 and 1996, respectively.
 
ITEM 6. SELECTED FINANCIAL DATA.
 
  Not required.
 
ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS.
 
1997 COMPARED TO 1996
 
  Net earnings applicable to common stock for 1997 were $36.6 million, an
increase of $7.5 million or 26% as compared to 1996. This increase primarily
reflects growth in throughput, lower operating expenses, the full year impact
of the 1996 rate order and a $2.0 million gain on the settlement of pension
obligations, partially offset by the margin impact of lower average customer
usage and warmer weather and a higher charge for depreciation reflecting
continued investment in system replacement and expansion. Weather for 1997 was
3% colder than normal but 2% warmer than 1996. Although weather for 1997 was
2% warmer than 1996, weather for the first quarter of 1997, when the Company
generates most of its revenues and earnings, was 9% warmer than the prior
year. The Company recorded a restructuring charge of approximately $8.7
million in the fourth quarter of 1997, reflecting management's decision to
exit the gas appliance repair and service business (See Note 10 of Notes to
Consolidated Financial Statements). The earnings impact of this non-recurring
charge was offset by a non-recurring increase in revenues as described below.
 
  Revenues in 1997 decreased by 0.6% primarily because of lower average
customer usage, the migration of customers from firm sales to transportation-
only service, and the impact of comparatively warmer weather, partially offset
by sales to new customers and the full year impact of the 1996 rate order. The
migration of customers from firm sales to transportation-only service has no
impact on the Company's earnings. The Company earns all of its margins on the
local distribution of gas and none on the sale of the commodity itself.
 
  During the fourth quarter of 1997, the Company recorded a non-recurring
increase in revenues of approximately $8.9 million related to a change as a
result of the 1996 rate ruling in the recovery mechanism for the portion of
bad debt expense associated with gas costs.
 
1996 COMPARED TO 1995
 
  Net earnings applicable to common stock for 1996 were $29.1 million, an
increase of $5.8 million or 25% from 1995. This increase primarily reflects
colder billing temperatures, increased customer demand, and the absence of
reengineering related charges. Weather for 1996 was 4% colder than normal and
5% colder than 1995. These factors were somewhat offset by higher operating
expenses, principally wages, benefits and marketing related costs. Increased
depreciation and property tax expense reflect continued investment in system
expansion and replacement.
 
  The reduction in interest expense reflects the refinancing during the fourth
quarter of 1995 and lower borrowing requirements.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  To meet cash requirements and support its commercial paper program, the
Company has available up to $75.0 million of Eastern's committed credit
agreement and a $40.0 million uncommitted line of credit. The Company also
maintains a bank credit agreement which provides for the borrowing of up to
$70.0 million for
 
                                       7
<PAGE>
 
the exclusive purpose of funding its inventory of gas supplies or to back
commercial paper issued for the same purpose.
 
  The Company expects capital expenditures for 1998 to be approximately $59
million. Capital expenditures will be largely for improvements to the
distribution system, for system expansion to meet customer demand and for
productivity improvements.
 
  The Company believes that projected cash flow from operations, in
combination with currently available resources, is more than sufficient to
meet 1998 capital expenditures and working capital requirements, dividends to
shareholders and normal debt repayments. The foregoing forward-looking
statement involves risks and uncertainties. The Company's actual experience
may differ materially from its current expectation for various reasons,
including unexpected capital expenditures or working capital requirements.
Moreover, there can be no assurance that the external capital resources
currently available will continue to be available or will be available on
terms and conditions advantageous to the Company.
 
OTHER MATTERS
 
  On May 16, 1997 the Company received a response from the Department
concerning its request for reconsideration, clarification and recalculation of
the Department's November 1996 rate order. The Department granted an
additional $1.9 million in revenues (a $6.3 million increase was granted in
the November 1996 Order) and reduced the productivity offset portion of the
Performance-Based Rate ("PBR") formula established in its November 1996 Order
by 50 basis points, from 2.00% to 1.50%. Compared to the Department's original
decision, these changes will add approximately $3.5 million to projected
revenue in 1998, increasing to about $8.0 million by 2002, the last year of
the plan. The Department also made modifications to the service quality
measures requested by the Company, but left unchanged the Company's maximum
annual exposure of $5.0 million for failing to achieve them. On June 5, 1997,
the Company filed a notice of appeal of the Department's orders to the
Massachusetts Supreme Judicial Court. The Company expects that the appeal will
take approximately one year, and that any relief granted by the court will be
prospective.
 
  On July 18, 1997, the Department directed all ten investor-owned gas
distribution companies in Massachusetts to undertake a collaborative process
with other stakeholders to develop common principles under which comprehensive
gas service unbundling might proceed. The Department deferred the second phase
of the Company's unbundling proceeding, which is to address residential
unbundling and a permanent capacity assignment method, subject to its
assessment of the progress of the collaborative discussions.
 
  On November 7, 1997, the Department approved rate schedules designed to
implement the Company's $1.8 million rate increase approved by the Department
in the Company's first annual performance-based regulatory plan compliance
proceeding.
 
  In its November 1996 order, the Department also approved the Company's
proposal to facilitate competition in the natural gas marketplace. Under the
approved service unbundling program, on an interim basis, eligible commercial
and industrial customers migrating from firm sales to firm transportation will
be assigned, at cost, a pro-rata share of the upstream pipeline capacity
purchased by the Company to serve them. At the Department's direction,
permanent assignment of upstream pipeline capacity is currently being
addressed as part of the collaborative process discussed above. The capacity
assignment method ultimately approved by the Department could permit capacity
to be acquired by marketers at less than cost. If this proves to be the case,
there can be no assurance that the Company will be permitted to recover such
costs until the Department has addressed their recoverability. The
restructuring collaborative is also examining how to extend unbundled
transportation service to residential customers.
 
  The Company may have or share responsibility under applicable environmental
law for the remediation of 17 former manufactured gas plant ("MGP") sites, as
described in Note 12 of Notes to Consolidated Financial Statements. A
subsidiary of New England Electric System ("NEES") has assumed responsibility
for remediating
 
                                       8
<PAGE>
 
10 of these sites, subject to a limited contribution from the Company. The
Company has recorded a liability of $19.5 million, which represents its best
estimate at this time of remediation costs, which may reasonably be estimated
to range from $17 million to $31 million. However, there can be no assurance
that such costs will not vary considerably from these estimates.
 
  By a rate order issued on May 25, 1990, the Department approved the recovery
of all prudently incurred environmental response costs associated with former
MGP sites over separate, seven-year amortization periods, without a return on
the unamortized balance. The Company has recognized an insurance receivable of
$3.4 million, reflecting a negotiated settlement with an insurance carrier for
environmental expense indemnity, and a regulatory asset of $16.1 million,
representing the expected rate recovery of environmental remediation costs,
net of the insurance settlement. The Company currently believes, in light of
the indemnity agreement with the NEES subsidiary and the Department rate order
on environmental cost recovery, that it is not probable that such costs will
materially affect its financial condition or results of operations.
 
  The Company has assessed the impact of the year 2000 with respect to its
information systems and is currently modifying those systems as part of a plan
which the Company believes will provide year 2000 compliance. Anticipated
spending for these modifications is being expensed as incurred and is not
expected to have a material impact on operating results or financial
condition.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
(1) ACCOUNTING POLICIES
 
  The accounting policies of Boston Gas Company (the "Company") conform to
generally accepted accounting principles and reflect the effects of the
ratemaking process in accordance with Statement of Financial Accounting
Standards No. 71 ("SFAS 71"), "Accounting for the Effects of Certain Types of
Regulation".
 
  The significant accounting policies followed by the Company and its
subsidiary are described below and in the following footnotes:
 
      Note 2--Cost of Gas Adjustment Clause and Deferred Gas Costs
      Note 3--Income Taxes
      Note 6--Pension Benefits
      Note 7--Postretirement Benefits Other Than Pensions
      Note 8--Leases
 
 Principles of Consolidation
 
  The Company is a wholly-owned subsidiary of Eastern Enterprises ("Eastern").
The consolidated financial statements include the accounts of the Company and
its wholly-owned subsidiary, Massachusetts LNG Incorporated ("Mass LNG"). All
material intercompany balances and transactions between the Company and its
subsidiary have been eliminated in consolidation.
 
  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 and
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.
 
 Regulation and Operations
 
  The Company is a gas distribution company engaged in the transportation and
sale of natural gas to residential, commercial and industrial customers. The
Company's service territory includes Boston and 73 other communities in
eastern and central Massachusetts.
 
  The Company's operations are subject to Massachusetts statutes applicable to
gas utilities. Its revenues, earnings and cash flows are highly seasonal, as
most of its throughput is directly related to temperature levels.
 
 Regulatory Assets and Liabilities
 
  The Company is regulated as to rates, accounting and other matters by the
Massachusetts Department of Telecommunications and Energy ("the Department").
Therefore, the Company accounts for the economic effects of regulation in
accordance with the provisions of SFAS 71. In the event the Company determines
that it no longer meets the criteria for following SFAS 71, the accounting
impact would be an extraordinary, non-cash charge to operations of an amount
that could be material. Criteria that give rise to the discontinuance of SFAS
71 include (1) increasing competition that restricts the Company's ability to
establish prices to recover specific costs or (2) a significant change in the
manner in which rates are set by regulators from cost-based regulation to
another regulation. The Company has reviewed these criteria and believes that
the continuing application of SFAS 71 is appropriate.
 
  Regulatory assets have been established that represent probable future
revenue to the Company associated with certain costs that will be recovered
from customers through the ratemaking process. Regulatory liabilities
represent probable future reductions in revenues associated with the amounts
that are to be credited to customers through the ratemaking process.

</TABLE>
 
  Regulatory liabilities total approximately $10,371,000 and $11,446,000 at
December 31, 1997 and 1996 and relate primarily to income taxes.
 
  As of December 31, 1997 all of the Company's regulatory assets and
regulatory liabilities are being reflected in rates charged to customers over
periods ranging from 1 to 22 years. For additional information regarding
deferred income taxes, postretirement benefit costs, environmental costs and
Order 636 transition costs, see footnotes 3, 7, 12 and 13, respectively.
 
 Impairment of Long-Lived Assets
 
  Statement of Financial Accounting Standards No. 121 ("SFAS 121") "Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to be
Disposed Of" which became effective for 1996, establishes accounting standards
for the impairment of long-lived assets. SFAS 121 also requires that
regulatory assets that are no longer probable of recovery through future
revenues be charged to earnings. SFAS 121 did not have an impact on the
Company's financial position or results of operations in 1997 and 1996.
 
 Depreciation
 
  Depreciation is provided at rates designed to amortize the cost of
depreciable property, plant and equipment over their estimated remaining
useful lives. The composite depreciation rate, expressed as a percentage of
the average depreciable property in service, was 5.19% in 1997, 5.15% in 1996
and 5.13% in 1995.
 
  Accumulated depreciation is charged with the original cost and cost of
removal, less salvage value, of units retired. Expenditures for repairs,
upkeep of units of property and renewal of minor items of property replaced
independently of the unit of which they are a part are charged to maintenance
expense as incurred.
 
 Gas Operating Revenues
 
  Gas operating revenues are recorded when billed. Revenue is not recorded for
the amount of gas distributed to customers, which is unbilled at the end of
the period; however, the cost of this gas is deferred as discussed in Note 2.
 
(2) COST OF GAS ADJUSTMENT CLAUSE AND DEFERRED GAS COSTS
 
  The cost of gas adjustment clause ("CGAC") requires the Company to adjust
its rates semi-annually for firm gas sales in order to track changes in the
cost of gas distributed with an annual adjustment of subsequent rates for any
collection over or under actual costs incurred. As a result, the Company
defers the cost of any firm gas that has been distributed, but is unbilled at
the end of a period, to a period in which the gas is billed to customers. In
its order of November 29, 1996 ("the 1996 Rate Order"), the Department
modified the CGAC to

(2) COST OF GAS ADJUSTMENT CLAUSE AND DEFERRED GAS COSTS (CONTINUED)
 
recover the gas cost portion of the Company's bad debt write-offs effective
December 1, 1996. The order also granted a local distribution adjustment
clause ("LDAC") to recover the amortization of all environmental response
costs associated with former manufactured gas plant ("MGP") sites, FERC Order
636 transition costs and costs related to the Company's various conservation
and load management programs from the Company's firm sales and transportation
customers. These costs were previously recovered through the CGAC.
 
(3) INCOME TAXES
 
  The Company is a member of an affiliated group of companies that files a
consolidated federal income tax return. The Company follows the policy,
established for the group, of providing for income taxes that would be payable
on a separate company basis. The Company's effective income tax rate was 36.9%
in 1997, which includes the effect of 1.8% related to prior years tax
benefits, 39.2% in 1996 and 39.1% in 1995. State taxes represent the majority
of the difference between the effective rate and the Federal income tax rate
for 1997, 1996 and 1995.
 
  A summary of the provision for income taxes for the three years ended
December 31 is as follows:

</TABLE>
 
  Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases. Deferred tax assets and liabilities are measured using enacted tax
rates expected to apply to taxable income in the years in which those
temporary differences are expected to be recovered or settled. The effect on
deferred tax assets and liabilities of a change in tax rates is recognized in
income in the period that includes the enactment date.
 
  At December 31, 1997 the Company has a regulatory liability of $3,255,000
which represents the tax benefit of unamortized investment tax credits. This
benefit is being passed on to customers over the lives of property giving rise
to the investment credit. The Company also has a regulatory liability for
excess deferred taxes being returned to customers over a 30 year period
pursuant to a 1988 rate order with a balance to be refunded to customers of
$7,116,000 as of December 31, 1997.
 
  For income tax purposes, the Company uses accelerated depreciation and
shorter depreciation lives, as permitted by the Internal Revenue Code.
Deferred federal and state taxes are provided for the tax effects of all
temporary differences between financial reporting and taxable income.
Significant items making up deferred tax assets and deferred tax liabilities
at December 31, 1997 and 1996 are as follows:

  There are no sinking fund requirements for the next five years related to
the $210,000,000 of Medium-Term Notes outstanding at December 31, 1997 and
none are callable prior to maturity.
 
  Annual maturities of capital lease obligations are $507,000, $561,000,
$620,000 and $55,000 for 1998 through 2001, respectively.

from its customers. The Company maintains a long-term credit agreement with a
group of banks which provides for the borrowing of up to $70,000,000 for the
exclusive purpose of funding its inventory of gas supplies or for backing
commercial paper issued for the same purpose. The Company had $55,502,000 and
$55,594,000 of commercial paper outstanding to fund its inventory of gas
supplies at December 31, 1997 and 1996, respectively. Since the commercial
paper is supported by the credit agreement, these borrowings have been
classified as non-current in the accompanying consolidated balance sheets. The
credit agreement includes a one-year revolving credit facility which may be
converted to a two-year term loan at the Company's option if the one-year
revolving credit facility is not renewed by the banks. The Company may select
the agent bank's prime rate or, at the Company's option, various pricing
alternatives. The agreement requires a facility fee of 1/12 of 1% on the
commitment. No borrowings were outstanding under this agreement during 1997
and 1996.
 
 Short-Term Debt and Lines of Credit
 
  Eastern maintains a credit agreement with a group of banks which provides
for the borrowing by Eastern of up to $100,000,000 (of which up to $75,000,000
may be borrowed or used to back commercial paper issued by the Company) at any
time through December 31, 2001. The interest rate for borrowings is the agent
bank's prime rate, or at the borrower's option, various pricing alternatives.
The Company had outstanding borrowings of $39,700,000 and $57,000,000 in
commercial paper not related to gas inventory financing at December 31, 1997
and 1996, respectively. The weighted average interest rate on these borrowings
was 6.19% at December 31, 1997 and 5.99% at December 31, 1996.
 
  In addition to the $75,000,000 available under the Eastern credit agreement,
the Company has an uncommitted line of credit of $40,000,000 under which it
may borrow through December 31, 1998. The interest rate for such borrowings is
a function of federal funds, money market or prime rates. There were no
borrowings outstanding under this uncommitted line at December 31, 1997 and
1996.
 
(5) PREFERRED STOCK
 
  The Company has outstanding 1,200,000 shares of 6.421% Cumulative Preferred
Stock, which is non-voting and has a liquidation value of $25 per share. The
preferred stock requires 5% annual sinking fund payments beginning on
September 1, 1999 with a final redemption on September 1, 2018. The preferred
stock is not callable prior to 2003.
 
(6) PENSION BENEFITS
 
  The Company, through retirement plans under collective bargaining agreements
and participation in Eastern's pension plans, provides retirement benefits for
substantially all of its employees. The benefits under these plans are based
on stated amounts for years of service or employee's average compensation
during the five years prior to retirement. The Company follows a policy of
funding retirement and employee benefit plans in accordance with the
requirements of the plans and agreements in sufficient amounts to satisfy the
"Minimum Funding Standards" of the Employee Retirement Income Security Act of
1974 ("ERISA").
 
  Net pension cost included the following components:

  For the periods 1997 and 1996, the expected long-term rate of return on
assets was 8.5% and the discount rate used in determining the actuarial
present value of the projected benefit obligation was 7.5%. The rate of
increase in future compensation levels was 4.75%-5.0% for 1997 and 1996.

(7) POSTRETIREMENT BENEFITS OTHER THAN PENSIONS
 
  In addition to providing pension benefits, the Company, through
participation in Eastern-administered plans and welfare plans under collective
bargaining agreements, provides certain health care and life insurance
benefits for retired employees. The expected cost of postretirement benefits
other than pensions is charged to expense during the period of the employee's
service. As of the date of adoption of Statement of Financial Accounting
Standards No. 106 ("SFAS 106"), "Employers Accounting for Postretirement
Benefits Other Than Pensions", the cumulative effect of the accounting change
("transition obligation") was $89,120,000. The 1996 Rate Order allowed
recovery of SFAS 106 costs, which includes current SFAS 106 expense and the
amortization of the regulatory asset related to the transition obligation.
 
  Net postretirement benefit costs included the following components:

  The Company established a 501(c) (9) Voluntary Employee Beneficiary
Association ("VEBA") Trust in 1991 to begin funding its postretirement benefit
obligation for collectively bargained employees. Plan assets are invested in
equity securities, fixed-income investments and money market instruments.
 
  The weighted average discount rate used in determining the accumulated
postretirement benefit obligation was 7.5% in 1997 and 1996. A 7% annual
increase in the cost of covered health care benefits was assumed for 1997 and
1996. This rate of increase is assumed to remain at 7% through 1999 and
decrease to 6% in 2000 and 5% thereafter. A 1% increase in the assumed health
care cost trend would have increased the postretirement benefit cost by
$382,000 in 1997 and $536,000 in 1996, and the accumulated postretirement
benefit obligation by $4,258,000 in 1997 and $6,253,000 in 1996.
 
(8) LEASES
 
  The Company and its subsidiary lease certain facilities and equipment under
long-term leases which expire on various dates through the year 2001. Total
rentals charged to income under all lease agreements were approximately
$10,112,000 in 1997, $8,418,000 in 1996 and $8,826,000 in 1995.
 
  The Company capitalizes its financing leases, which include liquefied
natural gas facilities and an operations center. The lease for the liquefied
natural gas facilities in Lynn and Salem expired June 30, 1997. On May 6, 1997
the Company filed a civil suit to determine its purchase rights under the
lease. Pending the court's decision or a negotiated outcome, the parties have
agreed that the Company will continue to operate and maintain the facilities.
A summary of property held under capital leases as of December 31 is as
follows:

(8) LEASES (CONTINUED)
 
  Under the terms of SFAS 71, the timing of expense recognition on capitalized
leases should conform with regulatory rate treatment. The Company has included
the rental payments on its financing leases in its cost of service for rate
purposes. Therefore, the total depreciation and interest expense that was
recorded on the leases was equal to the rental payments included in other
operating and maintenance expense in the accompanying consolidated statements
of earnings.
 
  The Company also has various operating lease agreements for office
facilities and other equipment. The remaining minimum rental commitments for
these and all other noncancelable leases, including the financing leases, at
December 31, 1997 is as follows:

(10) RESTRUCTURING CHARGE
 
  During the fourth quarter of 1997, the Company recorded a restructuring
charge of $8.7 million related to its decision to exit the gas appliance
repair and service business. The charge includes $5.4 million for employee
severance and termination benefits associated with the elimination of
approximately 130 bargaining unit and management positions. The remaining $3.3
million relates to the disposition of assets, the cancellation of lease
obligations, communications, legal and other related costs. The Company
expects the restructuring plan to be complete by the end of 1998. The
restructuring charge is reported as a component of operating expenses in the
consolidated statement of earnings.
 
(11) RELATED PARTY TRANSACTIONS
 
  The Company paid Eastern $4,300,000 in 1997, $4,048,000 in 1996, and
$4,117,000 in 1995 for legal, tax and corporate services rendered.
 
  In December 1996, Eastern Rivermoor Company, Inc., a wholly owned subsidiary
of Eastern, purchased the Company's primary operations center from a third
party and assumed the current lease agreement with the Company. During 1997
the Company paid $752,000 to Eastern Rivermoor Company, Inc.
 
  During 1996, Eastern entered into a joint venture with New England Electric
System ("NEES") to form AllEnergy Marketing Company, L.L.P., a new unregulated
energy marketing company. In the fourth quarter of 1997, Eastern sold its
interest to NEES. During 1997 and 1996, AllEnergy purchased gas from the
Company at prices and terms equivalent to those used in transacting business
with unrelated parties and totalled approximately $163,000 and $2,764,000,
respectively.
 
(12) ENVIRONMENTAL ISSUES
 
  The Company, like many other companies in the natural gas industry, is party
to governmental proceedings requiring investigation and possible remediation
of former manufactured gas plant ("MGP") sites. The Company may have or share
responsibility under applicable environmental laws for the remediation of 17
such sites. A subsidiary of New England Electric System ("NEES") has assumed
responsibility for remediating 10 of these sites, subject to a limited
contribution from the Company. The Company has estimated its potential share
of the costs of investigating and remediating former MGP sites in accordance
with Statement of Financial Accounting Standards No. 5, "Accounting for
Contingencies," and the American Institute of Certified Public Accountants
Statement of Position 96-1, "Environmental Remediation Liabilities." The
Company has recorded a liability of $19.5 million, which represents its best
estimate at this time of remediation costs, which may reasonably be estimated
to range from $17 million to $31 million. However, there can be no assurance
that such

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
(12) ENVIRONMENTAL ISSUES (CONTINUED)
 
costs will not vary considerably from these estimates. Factors that may bear
on costs differing from estimates include, without limit, changes in
regulatory standards, changes in remediation technologies and practices and
the type and extent of contaminants discovered at the sites.
 
  The Company is aware of 21 other former MGP sites within its service
territory. The NEES subsidiary has provided full indemnification to the
Company with respect to eight of these sites. At this time, there is
substantial uncertainty as to whether the Company has or shares responsibility
for remediating any of these other sites. No notice of responsibility has been
issued to the Company for any of these sites from any governmental
environmental authority.
 
  By a rate order issued on May 25, 1990, the Department approved the recovery
of all prudently incurred environmental response costs associated with former
MGP sites over separate, seven-year amortization periods, without a return on
the unamortized balance. The Company has recognized an insurance receivable of
$3.4 million, reflecting a negotiated settlement with an insurance carrier for
environmental expense indemnity, and a regulatory asset of $16.1 million,
representing the expected rate recovery of environmental remediation costs,
net of the insurance settlement. The Company currently believes, in light of
the indemnity agreement with the NEES subsidiary and the Department rate order
on environmental cost recovery, that it is not probable that such costs will
materially affect its financial condition or results of operations.
 
(13) PIPELINE TRANSITION COSTS
 
  Pursuant to FERC Order 636, pipelines were permitted to recover prudently
incurred transition costs, including (1) gas supply realignment costs or the
costs of renegotiating existing gas supply contracts with producers; (2)
unrecovered purchased gas adjustment costs or unrecovered gas costs at the
time the pipelines ceased the merchant function; (3) stranded costs or the
unrecovered costs of assets that cannot be assigned to customers of unbundled
services; and (4) new facilities costs or the costs of new facilities required
to physically implement the order.
 
  On March 8, 1995 the Department issued an order allowing for the recovery of
the Company's transition cost liability from customers. During 1997, the
Company's remaining obligation for transition cost liability was settled by
applying pipeline rate case refunds against such obligation.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Boston Gas Company:
 
  We have audited the accompanying consolidated balance sheets of Boston Gas
Company (a Massachusetts Corporation and wholly-owned subsidiary of Eastern
Enterprises) and subsidiary as of December 31, 1997 and 1996, and the related
consolidated statements of earnings, retained earnings and cash flows for each
of the three years in the period ended December 31, 1997. These consolidated
financial statements and the schedules referred to below are the
responsibility of the Company's management. Our responsibility is to express
an opinion on these consolidated financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Boston Gas
Company and subsidiary as of December 31, 1997 and 1996, and the results of
their operations and their cash flows for each of the three years in the
period ended December 31, 1997, in conformity with generally accepted
accounting principles.
 
  Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The schedules listed in the index to
consolidated financial statements are presented for purposes of complying with
the Securities and Exchange Commission's rules and are not a part of the basic
financial statements. These schedules have been subjected to the auditing
procedures applied in the audits of the basic financial statements and, in our
opinion, fairly state, in all material respects, the financial data required
to be set forth therein in relation to the basic financial statements taken as
a whole.

2.1  This Agreement shall become effective as of the date set forth hereinabove
     and shall continue in effect for a term ending on and including October 31,

                             SERVICE AGREEMENT   
                  APPLICABLE TO TRANSPORTATION OF NATURAL GAS
                           UNDER RATE SCHEDULE FTNN


          AGREEMENT made as of October 1, 1993, by and between CNG TRANSMISSION
CORPORATION, a Delaware corporation, hereinafter called "Pipeline," and BOSTON
GAS COMPANY, a Massachusetts corporation, hereinafter called "Customer."

          WITNESSETH: That, in consideration of the mutual covenants herein
contained, the parties hereto agree as follows:


                                   ARTICLE I
                                  QUANTITIES
                                  ----------

          A.  During the term of this Agreement, Pipeline will transport for
Customer, on a firm basis, and Customer may furnish, or cause to be furnished,
to Pipeline natural gas for such transportation, and Customer will accept, or
cause to be accepted, delivery from Pipeline of the quantities Customer has
tendered for transportation.

          B.  The maximum quantities of gas which Pipeline shall deliver and
which Customer may tender shall be as set forth on Exhibit A, attached hereto.


                                  ARTICLE II
                                     RATE
                                     ----

          A.  Unless otherwise mutually agreed in a written amendment to this
Agreement, beginning on October 1, 1993, Customer shall pay Pipeline for
transportation services rendered pursuant to this Agreement, the maximum rates
and charges provided under Rate Schedule FTNN set forth in Pipeline's effective
FERC Gas Tariff, including applicable surcharges and the Fuel Retention
Percentage.

          B.  Pipeline shall have the right to propose, file and make effective
with the Federal Energy Regulatory Commission or any other body having
jurisdiction, revisions to any applicable rate schedule, or to propose, file,
and make effective superseding rate schedules for the purpose of changing the
rate, charges, and other provisions thereof effective as to Customer; provided,
however, that (i) Section 2 of Rate Schedule FTNN "Applicability and Character
of Service," (ii) term, (iii) quantities, and (iv) points of receipt and points
of delivery shall not be subject to unilateral change under this Article. Said
rate schedule or superseding rate schedule and any revisions thereof which shall
be filed and made effective shall apply to and become a part of this Service
Agreement. The filing of such
<PAGE>
 
changes and revisions to any applicable rate schedule shall be without prejudice
to the right of Customer to contest or oppose such filing and its effectiveness.


                                  ARTICLE III
                               TERM OF AGREEMENT
                               -----------------

          Subject to all the terms and conditions herein, this Agreement shall
be effective as of October 1, 1993, and shall continue in effect for a primary
term through and including March 31, 2003, and from year to year thereafter,
until either party terminates this Agreement by giving written notice to the
other at least twelve months prior to the start of the next contract year.


                                  ARTICLE IV
                        POINTS OF RECEIPT AND DELIVERY
                        ------------------------------

          The Points of Receipt and Delivery and the maximum quantities for each
point for all gas that may be received for Customer's account for transportation
by Pipeline shall be as set forth on Exhibit A.


                                   ARTICLE V
                              REGULATORY APPROVAL
                              -------------------

          Performance under this Agreement by Pipeline and Customer shall be
contingent upon Pipeline and Customer receiving all necessary regulatory or
other governmental approvals upon terms satisfactory to each. Should Pipeline or
Customer be denied such approvals to provide or continue the service
contemplated herein, or to construct and operate any necessary facilities
therefore upon the terms and conditions requested in the application therefore,
then Pipeline's and Customer's obligations hereunder shall terminate.


                                  ARTICLE VI
                INCORPORATION BY REFERENCE OF TARIFF PROVISIONS
                -----------------------------------------------

          To the extent not inconsistent with the terms and conditions of this
Agreement, the following provisions of Pipeline's effective FERC Gas Tariff, and
any revisions thereof that may be made effective hereafter are hereby made

                                 MISCELLANEOUS

further written agreement either prior to the making of any request or filing
permitted under Article II hereof or prior to the effectiveness of such request
or filing after Commission approval, provided further, however, that nothing in
this Agreement shall be deemed to prejudice any position the parties may take as

                                  ARTICLE XII

      later than twelve months after the termination of this Agreement.

12.3  This Agreement will terminate automatically upon written notice from
      Transporter in the event Shipper fails to pay all of the amount of any

      later than twelve months after the termination of this Agreement.

12.3  This Agreement will terminate automatically upon written notice from
      Transporter in the event Shipper fails to pay all of the amount of any
      bill for service rendered by Transporter hereunder in accord with the
      terms and conditions of Article VI of the General Terms and Conditions of
      Transporter's FERC Tariff.

                        (For Use Under Rate Schedule FS)


This Contract is made as of the 1st day of December, 1994, by and between
TENNESSEE GAS PIPELINE COMPANY, a Delaware corporation herein called
"Transporter," and BOSTON GAS CO, a MASSACHUSETTS Corporation, herein called
"Shipper." Transporter and Shipper collectively shall be referred to herein as
the "Parties."


                         ARTICLE I - SCOPE OF AGREEMENT

Following the commencement of service hereunder, in accordance with the terms of
Transporter's Rate Schedule FS, and of this Agreement, Transporter shall receive
for injection for Shipper's account a daily quantity of gas up to Shipper's
Maximum Injection Quantity of 37,907 dekatherms (Dth) and Maximum Storage

withdraw from Shipper's storage account and deliver to Shipper a daily quantity
of gas up to Shipper's Maximum Daily Withdrawal Quantity (MDWQ) of 70,799 Dth;
provided however, that when Shipper's storage balance is equal to or less than
30% of the MSQ but greater than 20% of the MSQ, the Maximum Daily Withdrawal
Quantity shall be 70,799 Dth; and provided further, that when Shipper's storage
balance is less than or equal to 20% of the MSQ, the Maximum Daily Withdrawal
Quantity shall be 41,687 Dth. For demand charge purposes, the MDWQ for balances
greater than 30% of the MSQ shall be used.
                                          

                          ARTICLE II - SERVICE POINT

The point or points at which the gas is to be tendered for delivery

                              ARTICLE III - PRICE

1. Shipper agrees to pay Transporter for all natural gas storage service
   furnished to Shipper hereunder, including compensation for system fuel and
   losses, at Transporter's legally effective rate or at any effective
   superseding rate applicable to the type of service specified herein.
   Transporter's present legally effective rate for said service is contained in
   Transporter's Tariff as filed with the Federal Energy Regulatory Commission.

2. Shipper agrees to reimburse Transporter for any filing or similar fees, which
   have not been previously paid by Shipper, which Transporter incurs in
   rendering service hereunder.
<PAGE>
 
3. Shipper agrees that Transporter shall have the unilateral right to file with
   the appropriate regulatory authority and make changes effective in (a) the
   rates and charges applicable to service pursuant to Transporter's Rate
   Schedule FS, (b) the rate schedule(s) pursuant to which service hereunder is
   rendered, or (c) any provision of the General Terms and Conditions applicable
   to those rate schedules.  Transporter agrees that Shipper may protest or
   contest the aforementioned filings, or may seek authorization from duly
   constituted regulatory authorities for such adjustment of Transporter's
   existing FERC Gas Tariff as may be found necessary to assure Transporter just
   and reasonable rates.


ARTICLE IV - INCORPORATION OF RATE SCHEDULE AND TARIFF PROVISIONS

This agreement shall be subject to the terms of Transporter's Rate Schedule FS,
as filed with the Federal Energy Regulatory Commission, together with the
General Terms and Conditions applicable thereto (including any changes in said
Rate Schedule or General Terms and Conditions as may from time to time be filed
and made effective by Transporter).

                         ARTICLE V - TERM OF AGREEMENT

This Agreement shall be effective as of the December 1, 1994 and shall remain in
force and effect until November 1, 2000, ("Primary Term") and on a month to
month basis thereafter unless terminated by either Party upon at least thirty
(30) days prior written notice to the other Party; provided, however, that if
the Primary Term is one year or more, then unless Shipper elects upon one year's
prior written notice to Transporter to request a lesser extension term, the
Agreement shall automatically extend upon the expiration of the Primary Term for
a term of five years; and shall automatically extend for successive five year
terms thereafter unless Shipper provides notice described above in advance of
the expiration of a succeeding term;  provided further, if the FERC or other
governmental body having jurisdiction over the service rendered pursuant to this
Agreement authorizes abandonment of such service, this Agreement shall terminate
on the abandonment date permitted by the FERC or such other governmental body.

This Agreement will terminate upon notice from Transporter in the event Shipper
fails to pay all of the amount of any bill for service rendered by Transporter
hereunder in accordance with the  terms and conditions of Article VI of the
General Terms and Conditions of Transporters Tariff.

the extent that no new measurement facilities are installed to provide service

      Transporter's FERC Gas Tariff.

6.2   INCIDENTAL CHARGES - Shipper agrees to reimburse Transporter for any
      filing or similar fees, which have not been previously paid for by

      the unilateral right to file with the appropriate regulatory authority and
      make effective changes in (a) the rates and charges applicable to service

      the General Terms and Conditions applicable to those rate schedules.
      Transporter agrees that Shipper may protest or contest the aforementioned
      filings, or may seek authorization from duly constituted regulatory
      authorities for such adjustment of Transporter's existing FERC Gas Tariff
      as may be found necessary to assure Transporter just and reasonable rates.

                                  ARTICLE VII

  WHEREAS, by order issued January 13, 1993 (62 FERC P61,015) and order issued
April 22, 1993 (63 FERC P61,100), the Federal Energy Regulatory Commission
accepted Pipeline's revised tariff sheets filed in compliance with Order No. 636

  NOW, THEREFORE, in consideration of the premises and of the mutual covenants
and agreements herein contained, the parties do covenant and agree as follows:


                                   ARTICLE I

                                  (Continued)


such daily quantities tendered up to such Customer's MDQ.

  Pipeline shall not be obligated to, but may at its discretion, receive at any
Point of Receipt on any day a quantity of gas in excess of the applicable
Maximum Daily Receipt Obligation (MDRO), plus Applicable Shrinkage, but shall
not receive in the aggregate at all Points of Receipt on any day a quantity of

  In addition to the MDQ and subject to the terms, conditions and limitations
hereof, Rate Schedule FT-1 and the General Terms and Conditions, Pipeline shall
deliver within the Access Area under this and all other service agreements under
Rate Schedules CDS, FT-1, and/or SCT, quantities up to Customer's Operational

requested on any day.


                                  ARTICLE II

prior written notice to the other specifying a termination date of any year
occurring on or after the expiration of the primary term. In addition to
Pipeline rights under Section 22 of Pipeline's General Terms and Conditions and
without prejudice to such rights, this Service Agreement may be terminated at
any time by Pipeline in the event Customer fails to pay part or all of the
amount of any bill for service hereunder and such failure continues for thirty
(30) days after payment is due; provided, Pipeline gives thirty (30) days prior

supplier has retained processing rights to the gas delivered to Customer, the
appropriate agreements prior to the commencement of service for the

                                  (Continued)


Customer's account quantities of natural gas up to the following quantity:

           Maximum Daily Quantity (MDQ) 5,033 dth

  Pipeline shall receive for Customer's account, at those points on Pipeline's
system as specified in Article IV herein or available to Customer pursuant to
Section 14 of the General Terms and Conditions (hereinafter referred to as
Point(s) of Receipt) for transportation hereunder daily quantities of gas up to
Customer's MDQ, plus Applicable Shrinkage. Pipeline shall transport and deliver
for Customer's account, at those points on Pipeline's system as specified in
Article IV herein or available to Customer pursuant to Section 14 of the General
Terms and Conditions (hereinafter referred to as Point(s) of Delivery), such
daily quantities tendered up to such Customer's MDQ.

  Pipeline shall not be obligated to, but may at its discretion, receive at any
Point of Receipt on any day a quantity of gas in excess of the applicable
Maximum Daily Receipt Obligation (MDRO), plus Applicable Shrinkage, but shall
not receive in the aggregate at all Points of Receipt on any day a quantity of

not be obligated to, but may at its discretion, deliver at any Point of Delivery
on any day a quantity of gas in excess of the applicable Maximum Daily Delivery
Obligation (MDDO), but shall not deliver in the aggregate at all Points of
Delivery on any day a quantity of gas in excess of the applicable MDQ.

  In addition to the MDQ and subject to the terms, conditions and limitations
hereof, Rate Schedule FT-1 and the General Terms and Conditions, Pipeline shall
deliver within the Access Area under this and all other service agreements under
Rate Schedules CDS, FT-1, and/or SCT, quantities up to Customer's Operational

                                  ARTICLE II
                               TERM OF AGREEMENT

  The term of this Service Agreement shall commence on October 1, 1993 and shall

this Service Agreement is terminated as hereinafter provided. This Service
Agreement may be terminated by either Pipeline or Customer upon five (5) years
prior written notice to the other specifying a termination date of any year
occurring on or after the expiration of the primary term. Subject to Section 22
of Pipeline's General Terms and Conditions and without prejudice to such rights,

                                  (Continued)


Service Agreement may be terminated at any time by Pipeline in the event
Customer fails to pay part or all of the amount of any bill for service
hereunder and such failure continues for thirty (30) days after payment is due;
provided, Pipeline gives thirty (30) days prior written notice to Customer of
such termination and provided further such termination shall not be effective
if, prior to the date of termination, Customer either pays such outstanding bill
or furnishes a good and sufficient surety bond guaranteeing payment to Pipeline
of such outstanding bill.

  THE TERMINATION OF THIS SERVICE AGREEMENT WITH A FIXED CONTRACT TERM OR THE
PROVISION OF A TERMINATION NOTICE BY CUSTOMER TRIGGERS PREGRANTED ABANDONMENT

TERMINATION. PROVISION OF A TERMINATION NOTICE BY PIPELINE ALSO TRIGGERS
CUSTOMER'S RIGHT OF FIRST REFUSAL UNDER SECTION 3.13 OF THE GENERAL TERMS AND
CONDITIONS ON THE EFFECTIVE DATE OF THE TERMINATION.

imbalances under this Service Agreement as required by the General Terms and

parts of this Service Agreement until such time as such balancing has been
accomplished.

                                 RATE SCHEDULE

  This Service Agreement in all respects shall be and remain subject to the
applicable provisions of Rate Schedule FT-1 and of the General Terms and
Conditions of Pipeline's FERC Gas Tariff on file with the Federal Energy

  Customer shall pay Pipeline, for all services rendered hereunder and for the
availability of such service in the period stated, the applicable prices
established under Pipeline's Rate Schedule FT-1 as filed with the Federal Energy
Regulatory Commission, and as same may hereafter be legally amended or
superseded.

charges applicable to service pursuant to Pipeline's Rate Schedule FT-1, (b)
Pipeline's Rate Schedule FT-1 pursuant to which service hereunder is rendered or
(c) any provision of the General Terms and Conditions applicable to Rate

and Conditions. Customer agrees that in the event Customer tenders for service
hereunder and Pipeline agrees to accept natural gas which does not comply with
Pipeline's quality specifications, as expressly provided for in Section 5 of
Pipeline's General Terms and Conditions, Customer shall pay all costs associated
with processing of such gas as necessary to comply with such quality
specifications. Customer shall execute or cause its supplier to execute, if such
supplier has retained processing rights to the gas delivered to Customer, the
appropriate agreements prior to the commencement of service for the
transportation and processing of any liquefiable hydrocarbons and any PVR
quantities associated with the processing of gas received by Pipeline at the
Point(s) of Receipt under such Customer's service agreement. In addition,
subject to the execution of appropriate agreements, Pipeline is willing to

                               SERVICE AGREEMENT
                            FOR RATE SCHEDULE SS-1


     This agreement, made and entered into this 29 day of Nov., 1994, by and
between TEXAS EASTERN TRANSMISSION CORPORATION, a Delaware Corporation (herein
called "Pipeline") and BOSTON GAS COMPANY (herein called "Customer," whether
one or more),

                             W I T N E S S E T H:

     WHEREAS, there currently exists between Pipeline and Customer six service
agreements under Rate Schedule SS-1 (Pipeline's Contract Nos. 400139, 400140,
400141, 400217, 400218 and 412018) which specify an MDWQ of 12,232 dth and an
MSQ of 1,444,651 dth, an MDWQ of 9,338 dth and an MSQ of 653,660 dth, an MDWQ of
43,252 and an MSQ of 2,595,120 dth, an MDWQ of 9 dth and an MSQ of 630 dth, an
MDWQ of 51 dth and an MSQ of 3,570 dth, and an MDWQ of 712 and an MSQ of 49,840
respectively; and 

     WHEREAS, Pipeline and Customer desire to enter into one service agreement
under Rate Schedule SS-1 which shall supersede the six existing Rate Schedule 
SS-1 service agreements referenced above; and

     WHEREAS, withdrawal rights under the new Rate Schedule SS-1 service
agreement are consistent with the existing rights of the six existing Rate
Schedule SS-1 service agreements it supersedes;

     NOW, THEREFORE, in consideration of the premises and of the mutual
covenants and agreements herein contained, the parties do covenant and agree as
follows:


                                   ARTICLE I

                              SCOPE OF AGREEMENT

     Subject to the terms, conditions and limitations hereof and of Pipeline's
Rate Schedule SS-1, Pipeline agrees to provide firm service for Customer under
Rate Schedule SS-1 and to receive and store for Customer's account quantities of
natural gas up to the following quantity:

          Maximum Daily Injection Quantity (MDIQ) 24,403 dth 
          Maximum Storage Quantity (MSQ) 4,747,471 dth

     Pipeline agrees to withdraw from storage for Customer, at Customer's
request, quantities of gas up to Customer's Maximum Daily Withdrawal Quantity
(MDWQ) of 65,594 dekatherms, or such lesser quantity as determined pursuant to
Rate Schedule SS-1, from Customer's Storage Inventory, plus Applicable 
Shrinkage, and to
<PAGE>
 
                               SERVICE AGREEMENT
                            FOR RATE SCHEDULE SS-1
                                  (Continued)


deliver for Customer's account such quantities. Pipeline's obligation to
withdraw gas on any day is governed by the provisions of Rate Schedule SS-1,
including but not limited to Section 6.


                                  ARTICLE II

                               TERM OF AGREEMENT

     The term of this Service Agreement shall commence on December 1, 1994 and
shall continue in force and effect until April 30, 2013 and year to year
thereafter unless this Service Agreement is terminated as hereinafter provided.
This Service Agreement may be terminated by either Pipeline or Customer upon
five (5) years prior written notice to the other specifying a termination date
of any year occurring on or after the expiration of the primary term. Subject to
Section 22 of Pipeline's General Terms and Conditions and without prejudice to
such rights, this Service Agreement may be terminated at any time by Pipeline in
the event Customer fails to pay part or all of the amount of any bill for
service hereunder and such failure continues for thirty (30) days after payment
is due; provided, Pipeline gives thirty (30) days prior written notice to
Customer of such termination and provided further such termination shall not be
effective if, prior to the date of termination, Customer either pays such
outstanding bill or furnishes a good and sufficient surety bond guaranteeing
payment to Pipeline of such outstanding bill.

     THE TERMINATION OF THIS SERVICE AGREEMENT WITH A FIXED CONTRACT TERM OR THE
PROVISION OF A TERMINATION NOTICE BY CUSTOMER TRIGGERS PREGRANTED ABANDONMENT
UNDER SECTION 7 OF THE NATURAL GAS ACT AS OF THE EFFECTIVE DATE OF THE
TERMINATION. PROVISION OF A TERMINATION NOTICE BY PIPELINE ALSO TRIGGERS
CUSTOMER'S RIGHT OF FIRST REFUSAL UNDER SECTION 3.13 OF THE GENERAL TERMS AND
CONDITIONS ON THE EFFECTIVE DATE OF THE TERMINATION.

     In the event there is gas in storage for Customer's account on April 30 of
the year of termination of this Service Agreement, this Service Agreement shall
continue in force and effect for the sole purpose of withdrawal and delivery of
said gas to Customer for an additional one-hundred and twenty (120) days.

                                  ARTICLE III

                                 RATE SCHEDULE

     This Service Agreement in all respects shall be and remain subject to the
applicable provisions of Rate Schedule SS-1 and of the General Terms and
Conditions of Pipeline's FERC Gas Tariff on file with the Federal Energy
Regulatory Commission, all of which are by this reference made a part hereof.

     Customer shall pay Pipeline, for all services rendered hereunder and for
the availability of such service in the period stated, the applicable prices
established under Pipeline's Rate Schedule SS-1 as filed with the Federal Energy
Regulatory Commission and as the same may be hereafter revised or changed.

     Customer agrees that Pipeline shall have the unilateral right to file with
the appropriate regulatory authority and make changes effective in (a) the rates
and charges applicable to service pursuant to Pipeline's Rate Schedule SS-1, (b)
Pipeline's Rate Schedule SS-1, pursuant to which service hereunder is rendered
or (c) any provision of the General Terms and conditions applicable to Rate
Schedule SS-1. Notwithstanding the foregoing, Customer does not agree that
Pipeline shall have the unilateral right without the consent of Customer
subsequent to the execution of this Service Agreement and Pipeline shall not
have the right during the effectiveness of this Service Agreement to make any
filings pursuant to Section 4 of the Natural Gas Act to change the MDIQ, MSQ and
MDWQ specified in Article I, to change the term of the service agreement as
specified in Article II, to change Point(s) of Receipt Specified in Article IV,
to change the Point(s) of Delivery specified in Article IV, or to change the
firm character of the service hereunder. Pipeline agrees that Customer may
protest or contest the aforementioned filings, and Customer does not waive any
rights it may have with respect to such filings.

                 POINT(S) OF RECEIPT AND POINT(S) OF DELIVERY

     The natural gas received by Pipeline for Customer's account for storage
injection pursuant to this Service Agreement shall be those quantities scheduled
for delivery pursuant to Service Agreements between Pipeline and Customer under
Rate Schedules CDS, FT-1, SCT, PTI or IT-1 which specify as a Point of Delivery
the "SS-1 Storage Point". For purposes of billing of Usage Charges under Rate
Schedules CDS, FT-1, SCT, PTI or IT-1, deliveries under Rate Schedules CDS, FT-
1, SCT, PTI or IT-1 for injection into storage scheduled directly to the "SS-1
Storage Point" shall be deemed to have been delivered 60% in Market Zone 2 and
40% in Market Zone 3. In addition, at Customer's request any positive or
negative variance between scheduled deliveries and actual deliveries on any day
at Customer's Points of Delivery under Rate Schedules CDS, FT-1, SCT, or IT-1
shall be deemed for billing purposes delivered at the Point of Delivery and
shall be injected into or withdrawn from storage for Customer's account. In
addition to accepting gas for storage injection at the SS-1 Storage Point,
Pipeline will accept gas tendered at points of interconnection between Pipeline
and third party facilities at Oakford and Leidy Storage Fields provided that
such receipt does not result in Customer tendering aggregate quantities for
storage in excess of the Customer MDIQ.

     The Point(s) of Delivery at which Pipeline shall deliver gas shall be
specified in Exhibit A of the executed service agreement.

     Exhibit A and B are hereby incorporated as part of this Service Agreement
for all intents and purposes as if fully copied and set forth herein at length.


                                   ARTICLE V

                                    QUALITY

     All natural gas tendered to Pipeline for Customer's account shall conform
and be subject to the provisions of Section 5 of the General Terms and
Conditions. Customer agrees that in the event Customer tenders for service
hereunder and Pipeline agrees to accept natural gas which does not comply with
Pipeline's quality

                            FOR RATE SCHEDULE FSS-1

     This agreement, made and entered into this 29 day of Nov, 1994, by and
between TEXAS EASTERN TRANSMISSION CORPORATION, a Delaware Corporation (herein
called "Pipeline") and BOSTON GAS COMPANY (herein called "Customer," whether one
or more),

                             W I T N E S S E T H:

     WHEREAS, there currently exists between Pipeline and Customer three service
agreements under Rate Schedule FSS-1 (Pipeline's Contract Nos. 400503, 400520
and 400521) which specify an MDWQ of 2,932 dth and an MSQ of 175,920 dth, an
MDWQ of 36 dth and an MSQ of 2,160 dth, and an MDWQ of 209 dth and an MSQ of
12,540 dth respectively; and

     WHEREAS, Pipeline and Customer desire to enter into one service agreement
under Rate Schedule FSS-1 which shall supersede the three referenced above; and

     WHEREAS, withdrawal rights under the new Rate Schedule FSS-1 service
agreement are consistent with the existing rights of the three existing Rate
Schedule FSS-1 service agreements it supersedes;

     NOW, THEREFORE, in consideration of the premises and of the mutual
covenants and agreements herein contained, the parties do covenant and agree as
follows:
                                   ARTICLE I

                              SCOPE OF AGREEMENT

     Subject to the terms, conditions and limitations hereof and of Pipeline's
Rate Schedule FSS-1, Pipeline agrees to provide firm service for Customer under
Rate Schedule FSS-1 and to receive and store for Customer's account quantities
of natural gas up to the following quantity:

          Maximum Daily Injection Quantity (MDIQ) 979 dth 
          Maximum Storage Quantity (MSQ) 190,620 dth

     Pipeline agrees to withdraw from storage for Customer, at Customer's
request, quantities of gas up to Customer's Maximum Daily Withdrawal Quantity
(MDWQ) of 3,177 dekatherms, or such lesser quantity as determined pursuant to
Rate Schedule FSS-1, from Customer's Storage Inventory, plus Applicable
Shrinkage. Pipeline's obligation to withdraw gas on any day is governed by the
provisions of Rate Schedule FSS-1, including but not limited to Section 6.

                            FOR RATE SCHEDULE FSS-1
                                  (Continued)

                                  ARTICLE II

                               TERM OF AGREEMENT

     The term of this Service Agreement shall commence on December 1, 1994 and
shall continue in force and effect until April 30, 2012 and year to year
thereafter unless this Service Agreement is terminated as hereinafter provided.
This Service Agreement may be terminated by either Pipeline or Customer upon
five (5) years prior written notice to the other specifying a termination date
of any year occurring on or after the expiration of the primary term.

     Subject to Pipeline rights under Section 22 of Pipeline's General Terms and
Conditions and without prejudice to such rights, this Service Agreement may be
terminated at any time by Pipeline in the event Customer fails to pay part or
all of the amount of any bill for service hereunder and such failure continues
for thirty (30) days after payment is due; provided, Pipeline gives thirty (30)
days prior written notice to Customer of such termination and provided further
such termination shall not be effective if, prior to the date of termination,
Customer either pays such outstanding bill or furnishes a good and sufficient
surety bond guaranteeing payment to Pipeline of such outstanding bill.

THE TERMINATION OF THIS SERVICE AGREEMENT WITH A FIXED CONTRACT TERM OR THE
PROVISION OF A TERMINATION NOTICE BY CUSTOMER TRIGGERS PREGRANTED ABANDONMENT
UNDER SECTION 7 OF THE NATURAL GAS ACT AS OF THE EFFECTIVE DATE OF THE
TERMINATION. PROVISION OF A TERMINATION NOTICE BY PIPELINE ALSO TRIGGERS
CUSTOMER'S RIGHT OF FIRST REFUSAL UNDER SECTION 3.13 OF THE GENERAL TERMS AND
CONDITIONS ON THE EFFECTIVE DATE OF THE TERMINATION.

     In the event there is gas in storage for Customer's account on April 30 of
the year of termination of this Service Agreement, this Service Agreement shall
continue in force and effect for the sole purpose of withdrawal and delivery of
said gas to Customer for an additional one-hundred and twenty (120) days.

                                  ARTICLE III

                                 RATE SCHEDULE

     This Service Agreement in all respects shall be and remain subject to the
applicable provisions of Rate Schedule FSS-1 and of the General Terms and
Conditions of Pipeline's FERC Gas Tariff on file with the Federal Energy
Regulatory Commission, all of which are by this reference made a part hereof.

     Customer shall pay Pipeline, for all services rendered hereunder and for
the availability of such service in the period stated, the applicable prices
established under Pipeline's Rate Schedule FSS-1 as filed with the Federal
Energy Regulatory Commission and as the same may be hereafter revised or
changed.

                            FOR RATE SCHEDULE FSS-1
                                  (Continued)


     Customer agrees that Pipeline shall have the unilateral right to file with
the appropriate regulatory authority and make changes effective in (a) the rates
and charges applicable to service pursuant to Pipeline's Rate Schedule FSS-1,
(b) Pipeline's Rate Schedule FSS-1, pursuant to which service hereunder is
rendered or (c) any provision of the General Terms and Conditions applicable to
Rate Schedule FSS-1. Notwithstanding the foregoing, Customer does not agree that
Pipeline shall have the unilateral right without the consent of Customer
subsequent to the execution of this Service Agreement and Pipeline shall not
have the right during the effectiveness of this Service Agreement to make any
filings pursuant to Section 4 of the Natural Gas Act to change the MDIQ, MSQ and
MDWQ specified in Article I, to change the term of the service agreement as
specified in Article II, to change Point(s) of Receipt specified in Article IV,
to change the Point(s) of Delivery specified in Article IV, or to change the
firm character of the service hereunder. Pipeline agrees that Customer may
protest or contest the aforementioned filings, and Customer does not waive any
rights it may have with respect to such filings.

                                  ARTICLE  IV

                 POINT(S) OF RECEIPT AND POINT(S) OF DELIVERY

     The natural gas received by Pipeline for Customer's account for storage
injection pursuant to this Service Agreement shall be those quantities scheduled
for delivery pursuant to Service Agreements between Pipeline and Customer under
Rate Schedules CDS, FT-1, SCT, PTI or IT-1 which specify as a Point of Delivery
the "FSS-1 Storage Point". For purposes of billing of Usage Charges under Rate
Schedules CDS, FT-1, SCT, PTI or IT-1, deliveries under Rate Schedules CDS, FT-
1, SCT, PTI or IT-1 for injection into storage scheduled directly to the "FSS-1
Storage Point" shall be deemed to have been delivered 60% in Market Zone 2 and
40% in Market Zone 3. In addition, subject to Pipeline's prior written consent,
any positive variance between scheduled deliveries and actual deliveries on any
day (i.e. scheduled deliveries exceed actual deliveries) at Customer's Points of
Delivery under Rate Schedules CDS, FT-1, SCT, or IT-1 shall be deemed for
billing purposes delivered at the Point of Delivery and shall be injected into
storage for Customer's account. In addition to accepting gas for storage
injection at the FSS-1 Storage Point, Pipeline will accept gas tendered at
points of interconnection between Pipeline and third party facilities at Oakford
and Leidy Storage Fields provided that such receipt does not result in Customer
tendering aggregate quantities for storage in excess of the Customer MDIQ.

     The natural gas delivered by Pipeline for Customer's account as a result of
storage withdrawal pursuant to this Service Agreement shall be those quantities
scheduled for withdrawal hereunder and subsequent transportation pursuant to
service agreements between Pipeline and Customer under Rate Schedule CDS, FT-1,
SCT, or IT-1 which specify as a Point of Receipt the "FSS-1

Storage Point". For purpose of billing under Rate Schedules CDS, FT-1, SCT, or
IT-1, withdrawals from storage for subsequent transportation under Rate
Schedules CDS, FT-1, SCT, or IT-1 shall be deemed to have been received 60% in
Market Zone 2 and 40% in Market Zone 3. In addition to the withdrawal of gas
from storage for delivery through a transportation service on Pipeline's system,
gas may be withdrawn for delivery into the facilities of third parties at the
points of interconnection between Pipeline and the facilities of such third
parties at Oakford and Leidy Storage Fields provided that such withdrawals do
not result in Customer withdrawing gas in excess of his MDWQ or MSQ. A separate
transportation charge will not be applicable to these deliveries.


                                   ARTICLE V

                                    QUALITY

     All natural gas tendered to Pipeline for Customer's account shall conform
and be subject to the provisions of Section 5 of the General Terms and
Conditions. Customer agrees that in the event Customer tenders for service
hereunder and Pipeline agrees to accept natural gas which does not comply with
Pipeline's quality specifications, as expressly provided for in Section 5 of
Pipeline's General Terms and Conditions, Customer shall pay all costs associated
with processing of such gas as necessary to comply with such quality
specifications.


                                  ARTICLE VI

                                   ADDRESSES

     Except as herein otherwise provided or as provided in the General Terms and
Conditions of Pipeline's FERC Gas Tariff, any notice, request, demand,
statement, bill or payment provided for in this Service Agreement, or any notice
which any party may desire to give to the other, shall be in writing and shall
be considered as duly delivered when mailed by registered, certified, or regular

     Any Company which shall succeed by purchase, merger, or consolidation to
the properties, substantially as an entirety, of Customer, or of Pipeline, as
the case may be, shall be entitled to the rights and shall be subject to the

Customer or Pipeline may assign or pledge this Service Agreement under the
provisions of any mortgage, deed of trust, indenture, bank credit agreement,
assignment, receivable sale, or similar instrument which it has executed or may
execute hereafter; otherwise, neither Customer nor Pipeline shall assign this
Service Agreement or any of its rights hereunder unless it first shall have
obtained the consent thereto in writing of the other; provided further, however,
that neither Customer nor Pipeline shall be released from its obligations
hereunder without the consent of the other. In addition, Customer may assign its
rights to capacity pursuant to Section 3.14 of the General Terms and Conditions.
To the extent Customer so desires, when it releases capacity pursuant to Section
3.14 of the General Terms and Conditions, Customer may require privity between
Customer and the Replacement Customer, as further provided in the applicable
Capacity Release Umbrella Agreement.

Agreement by Customer, and shall continue in force and effect until October 31,
2012 and year to year thereafter unless this Service Agreement is terminated as
hereinafter provided. This Service Agreement may be terminated by either
Pipeline or Customer upon five (5) years prior written notice to the other
specifying a termination date of any October 31 of any year occurring on or
after the expiration of the primary term. Subject to Section 22 of Pipeline's
General Terms and Conditions and without prejudice to such rights, this Service
Agreement may be terminated at any time by Pipeline in the event Customer fails
to pay part or all of the amount of any bill for service hereunder and such
failure continues for thirty (30) days after payment is due; provided, Pipeline
gives thirty (30) days prior written notice to Customer of such termination and
provided further such termination shall not be effective if, prior to the date
of termination, Customer either pays such outstanding bill or furnishes a good
and sufficient surety bond guaranteeing payment to Pipeline of such outstanding
bill.

     THE TERMINATION OF THIS SERVICE AGREEMENT WITH A FIXED CONTRACT TERM OR THE
PROVISION OF A TERMINATION NOTICE BY CUSTOMER TRIGGERS PREGRANTED ABANDONMENT
UNDER SECTION 7 OF THE NATURAL GAS ACT AS OF THE EFFECTIVE DATE OF THE
TERMINATION.

                                  (Continued)

have the right during the effectiveness of this Service Agreement to make any
filings pursuant to Section 4 of the Natural Gas Act to change the MDQ specified

Massachusetts corporation, hereinafter referred to as "Customer,"
- -------------

                                  WITNESSETH:

        WHEREAS, Customer has natural gas which cannot be moved into its system
through its existing facilities; and

        WHEREAS, Texas Gas has the ability in its pipeline system to move
natural gas for the account of Customer; and

        WHEREAS, Customer desires that Texas Gas transport such natural gas for
the account of Customer; and

        WHEREAS, Customer and Texas Gas are of the opinion that the transaction
referred to above falls within the provisions of Section 284.223 of Subpart G of
Part 284 of the Federal Energy Regulatory Commission's (Commission) regulations
and the blanket certificate issued to Texas Gas in Docket No. CP88-686-000, and
can be accomplished without the prior approval of the Commission;

        NOW, THEREFORE, in consideration of the premises and of the mutual
covenants herein contained, the parties hereto covenant and agree as follows:


                                   ARTICLE I

Definitions
- -----------

1.1     Definition of Terms of the General Terms and Conditions of Texas Gas's
FERC Gas Tariff on file with the Commission is hereby incorporated by reference
and made a part of this Agreement.


                                  ARTICLE II

Transportation Service
- ----------------------

2.1     Subject to the terms and provisions of this Agreement, Customer agrees
to deliver or cause to be delivered to Texas Gas, at the Point(s) of Receipt in
Exhibit "A" hereunder, Gas for Transportation, and Texas Gas agrees to receive,
transport, and redeliver, at the Point(s) of Delivery in Exhibit "B" hereunder,
Equivalent Quantities of Gas to Customer or for the account of Customer, in
accordance with Section 3 of Texas Gas's effective FT Rate Schedule and the
terms and conditions contained herein, up to 13,280 MMBtu per day during the
winter season, and up to 13,280 MMBtu per day during the summer
<PAGE>
 
season, which shall be Customer's Firm Transportation Contract Demand, and up to
2,005,280 MMBtu during the winter season, and up to 2,841,920 MMBtu during the
summer season, which shall be Customer's Seasonal-Quantity Levels.

2.2     Customer shall reimburse Texas Gas for the Quantity of Gas required for
fuel, company use, and unaccounted for associated with the transportation
service hereunder in accordance with Section 16 of the General Terms and
Conditions of Texas Gas's FERC Gas Tariff. The applicable fuel retention
percentage(s) is shown on Exhibit "A". Texas Gas may adjust the fuel retention
percentage as operating circumstances warrant; however, such change shall not be
retroactive. Texas Gas agrees to give Customer thirty (30) days written notice
before changing such percentage.

2.3     Texas Gas, at its sole option, may, if tendered by Customer, transport
daily quantities in excess of the Transportation Contract Demand.

2.4     In order to protect its system, the delivery of gas to its customers
and/or the safety of its operations, Texas Gas shall have the right to vent
excess natural gas delivered to Texas Gas by Customer or Customer's supplier(s)
in that part of its system utilized to transport gas received hereunder. Prior
to venting excess gas, Texas Gas will use its best efforts to contact Customer
or Customer's supplier in an attempt to correct such excess deliveries to Texas
Gas. Texas Gas may vent such excess gas solely within its reasonable judgment
and discretion without liability to Customer, and a pro rata share of any gas so
vented shall be allocated to Customer. Customer's pro rata share shall be
determined by a fraction, the numerator of which shall be the quantity of gas
delivered to Texas Gas at the Point of Receipt by Customer or Customer's
suppliers in excess of Customer's confirmed nomination and the denominator of
which shall be the total quantity of gas in excess of total confirmed
nominations flowing in that part of the Texas Gas's system utilized to transport
gas, multiplied by the total quantity of gas vented or lost hereunder.

2.5     Any gas imbalance between receipts and deliveries of gas, less fuel and
PVR adjustments, if applicable, shall be cleared each month in accordance with
Section 17 of the General Terms and Conditions in Texas Gas's FERC Gas Tariff.
Any imbalance remaining at the termination of this Agreement shall also be
cashed-out as provided herein.

                                  ARTICLE III

Scheduling
- ----------

3.1     Customer shall be obligated five (5) working days prior to the end of
each month to furnish Texas Gas with a schedule of the estimated daily
quantity(ies) of gas it desires to be received, transported, and redelivered for
the following month. Such schedules will show the quantity(ies) of gas Texas Gas
will receive from Customer at the Point(s) of Receipt, along with the identity
of the supplier(s) that is delivering or causing to be delivered to Texas Gas
quantities for Customer's account at each Point of Receipt for which a
nomination has been made.

                                       2
<PAGE>
 
3.2     Customer shall give Texas Gas, after the first of the month, at least
twenty-four (24) hours notice prior to the commencement of any day in which
Customer desires to change the quantity(ies) of gas it has scheduled to be
delivered to Texas Gas at the Point(s) of Receipt.  If Customer's nomination
change does not require Texas Gas to interrupt service to another Customer,
Texas Gas will agree to waive this 24-hour prior notice and implement nomination
changes requested by Customer to commence in such lesser time frame subject to
Texas Gas's being able to confirm and verify such nomination change at both
Receipt and Delivery Points, and receive PDAs reflecting this nomination change
at both Receipt and Delivery Points.  Texas Gas will use its best efforts to
make the nomination change effective at the time requested by Customer; however,
if Texas Gas is unable to do so, the nomination change will be implemented as
soon as confirmation is received.

                                  ARTICLE VII

Facilities
- ----------

7.1     Texas Gas and Customer agree that any facilities required at the
Point(s) of Receipt, Point(s) of Delivery, and Point(s) of Measurement, shall be
installed, owned, and operated as specified in Exhibits A, A-I, and B herein.
Customer may be required to pay or cause Texas Gas to be paid for the installed
cost of any new facilities required as contained in Sections 1.3, 1.4, and 1.5
of Texas Gas's FT Rate Schedule. Customer shall only be responsible for the
installed cost of any new facilities described in this Section if agreed to in
writing between Texas Gas and Customer.

                                 ARTICLE VIII

Rates and Charges
- -----------------

8.1     Each month, Customer shall pay Texas Gas for the service hereunder, an
amount determined in accordance with Section 5 of Texas Gas's FT Rate Schedule
contained in Texas Gas's FERC Gas Tariff and as indicated on Exhibit "A" herein,
which Rate Schedule is by reference made a part of this Agreement. The maximum
rates for such service consist of a monthly reservation charge multiplied by
Customer's firm transportation demand as specified in Section 2.1 herein. The
reservation charge shall be billed as of the effective date of this Agreement.
In addition to the monthly reservation charge, Customer agrees to pay Texas Gas
each month the maximum commodity charge up to Customer's Transportation Contract
Demand. For any quantities delivered by Texas Gas in excess of Customer's
Transportation Contract Demand, Customer agrees to pay the maximum FT overrun
commodity charge. In addition, Customer agrees to pay:

    (a) Texas Gas's Fuel Retention percentage(s).

    (b) The currently effective GRI funding unit, if applicable, the currently
        effective FERC Annual Charge Adjustment unit charge (ACA), the currently
        effective Take-or-Pay surcharge, or any other then currently effective
        surcharges, including but not limited to Order 636 Transition Costs.

If Texas Gas declares force majeure which renders it unable to perform service
herein,  then Customer shall be relieved of its obligation to pay demand charges
for that part of its FT Contract Demand affected by such force majeure event
until the force majeure event is remedied.

                                       4
<PAGE>
 
Unless otherwise agreed to in writing by Texas Gas and Customer, Texas Gas may,
from time to time, and at any time selectively after negotiation, adjust the
rate(s) applicable to any individual Customer; provided, however, that such
adjusted rate(s) shall not exceed the applicable Maximum Rate(s) nor shall they
be less than the Minimum Rate(s) set forth in the currently effective Sheet No.
10 of this Tariff. If Texas Gas so adjusts any rates to any Customer, Texas Gas
shall file with the Commission any and all required reports respecting such
adjusted rate.

8.2     In the event Customer utilizes a Secondary Point(s) of Receipt or
Delivery for transportation service herein, Customer will continue to pay the
monthly reservation charges as described in Section 8.1 above. In addition,
Customer will pay the maximum commodity charge applicable to the zone in which
gas is received and redelivered up to Customer's Transportation Contract Demand
and the maximum overrun commodity charge for any quantities delivered by Texas
Gas in excess of Customer's winter season or summer season Transportation
Contract Demand. Customer also agrees to pay the ACA, Take-or-Pay Surcharge, GRI
charges, fuel retention charge, and any other effective surcharges, if
applicable, as described in Section 8.1 above.

8.3     It is further agreed that Texas Gas may seek authorization from the
Commission and/or other appropriate body for such changes to any rate(s) and
terms set forth herein or in Rate Schedule FT, as may be found necessary to
assure Texas Gas just and reasonable rates. Nothing herein contained shall be
construed to deny Customer any rights it may have under the Natural Gas Act, as
amended, including the right to participate fully in rate proceedings by
intervention or otherwise to contest increased rates in whole or in part.

8.4     Customer agrees to fully reimburse Texas Gas for all filing fees, if
any, associated with the service contemplated herein which Texas Gas is required
to pay to the Commission or any agency having or assuming jurisdiction of the
transactions contemplated herein.

8.5     Customer agrees to execute or cause its supplier or processor to execute
a separate agreement with Texas Gas providing for the transportation of any
liquids and/or liquefiables, and agrees to pay or reimburse Texas Gas, or
cause Texas Gas to be paid or reimbursed, for any applicable rates or charges
associated with the transportation of such liquids and/or liquefiables, as
specified in Section 24 of the General Terms and Conditions of Texas Gas' FERC
Gas Tariff.
