ITEM 1.  BUSINESS.
 
GENERAL DEVELOPMENT OF BUSINESS
 
     Boston Gas Company (the "Company") is engaged in the transportation,
distribution and sale of natural gas to residential, commercial, and industrial
customers which includes the City of Boston, Massachusetts, and 73 other
Massachusetts communities. The Company has one subsidiary, Massachusetts LNG
Incorporated ("Mass LNG"), which holds a long-term lease on two liquefied
natural gas facilities. The Company has been in business for 171 years and is
the second oldest gas company in the United States. Since 1929, all of the
common stock of the Company has been owned by Eastern Enterprises ("Eastern"),
which is headquartered in Weston, Massachusetts.

(A) The heating classification includes all gas sold to customers having central
    or space heating.
 
(B) The commercial classification includes central-metered apartment houses and
    condominiums with five or more units.
</TABLE>
 
     Firm gas sales are made under rate schedules or contracts with customers
who do not contemplate service interruption. Firm sales of natural gas sold for
purposes of space heating are directly related to weather conditions.
Consequently, variations in weather patterns can have a significant impact upon
the Company's revenues and earnings. The Company also provides seasonal firm
sales and transportation services to customers for terms of less than 365 days.
 
     Non-firm sales include interruptible sales made pursuant to contracts with
customers who typically can use oil and gas interchangeably and special sales
for resale to other gas companies for distribution to their
 
                                        1
<PAGE>   3
 
customers. Non-firm sales are dependent upon gas supply availability, weather
conditions and the price of gas in relation to the price of alternate fuels. The
price the Company charges is generally tied to the price of the customer's
alternate fuel. Availability of gas supply and price competition from residual
oil are important factors in retaining non-firm sales. Beginning November 1,
1993, gross margins from non-firm sales and transportation services ($8,434,000
in 1993 and $10,248,000 in 1992) are passed back to firm customers through the
cost of gas adjustment clause up to a threshold based upon the prior season's
experience. Non-firm margins realized in excess of the threshold are shared
between shareholders and core customers 25% and 75%, respectively.
 
     One customer accounted for 4.0% of the Company's operating revenues in
1993, 2.3% in 1992 and 3.5% in 1991.
 
GAS SUPPLY
 
     The Company purchases approximately 70% of its pipeline gas supplies
directly from producers and marketers pursuant to long-term contracts which are
subject to review and approval by the Massachusetts Department of Public
Utilities ("Department"). Seven of the Company's direct purchase agreements have
been approved by the Department including two long-term Canadian agreements.
Five other long-term agreements are pending before the Department, with orders
expected by April, 1994. The Company purchases its remaining pipeline supplies
pursuant to short-term, firm winter service agreements and on a spot basis.
Pipeline supplies are transported on interstate pipeline systems to the
Company's service territory pursuant to transportation agreements approved by
the Federal Energy Regulatory Commission ("FERC"). The Company has also
contracted with pipeline companies and others for the storage of natural gas and
related transportation from underground storage fields located in New York and
Pennsylvania. Supplemental supplies of liquefied natural gas ("LNG") and propane
are purchased and produced from foreign and domestic sources.
 
     All interstate pipelines serving the Company have implemented service
restructuring plans on terms and conditions approved by FERC pursuant to Order
No. 636. Order No. 636, issued April 8, 1992, required interstate pipeline
companies to unbundle existing gas service contracts into separate gas sales,
transportation and storage services. Accordingly, the Company's firm bundled
service with Algonquin Gas Transmission Company ("Algonquin"), a wholly-owned
subsidiary of Algonquin Energy, Inc., a wholly-owned subsidiary of Texas Eastern
Transmission Corporation ("Texas Eastern"), itself a wholly-owned subsidiary of
Panhandle Eastern Corporation, was converted to an annual firm transportation
entitlement of 65,600 MMCF. Similarly, the Company's firm bundled sales service
with Texas Eastern has been converted to an annual firm transportation
entitlement of 100,100 MMCF; and its firm bundled sales service with Tennessee
Gas Pipeline Company, a division of Tenneco, Inc. ("Tennessee"), has been
converted to an annual firm transportation entitlement of 77,800 MMCF. In
addition, as a result of industry restructuring, the Company has firm
entitlements on interstate pipelines upstream of Tennessee, Texas Eastern, and
Algonquin, with direct access to supply areas. Together, these transportation
entitlements are used to transport natural gas purchased by the Company from
producing regions and underground storage facilities to our service territory.
After restructuring, the Company now holds direct entitlements to 16,500 MMCF of
storage capacity with Tennessee, Texas Eastern and others. These new
transportation and storage agreements with Algonquin, Texas Eastern, and
Tennessee have terms generally expiring no earlier than November 1996, April
2012, and April 2000, respectively. The Company is provided rights of first
refusal under Order No. 636 to extend the terms of such service. The Company
considers the service reliability of its natural gas portfolio after industry
restructuring to be comparable to that existing prior to Order No. 636.
 
     In addition to its domestic supply arrangements, the Company has three
contracts for the purchase of Canadian gas supplies. The Company's contract with
Boundary, Inc. provides for the purchase of 3,845 MMCF of gas annually and
expires on January, 2003. The Company also has contracts with Alberta Northeast
Gas, Ltd. ("ANE") to purchase up to 6,242 MMCF of gas annually, and with
Imperial Oil of Canada, Ltd. ("Imperial"), formerly Esso Resources Canada, Ltd.,
for the purchase of 12,775 MMCF of gas annually. These contracts expire on
November, 2003 and April, 2007, respectively. The Company has contracted with
Iroquois Gas Transmission System ("IGTS"), Tennessee and Algonquin to transport
these
 
                                        2
<PAGE>   4
gas supplies from the Canadian border to delivery points in the Company's
service territory. All necessary Canadian government approvals for the purchase,
import, and transportation of these volumes have been issued.
 
     The Company has contracts, expiring in 1998, with Distrigas of
Massachusetts Corporation ("DOMAC") for the purchase of an annual quantity of up
to 2,000 MMCF of LNG and for 1,000 MMCF of LNG storage capacity and related
vaporization services. The Company also purchases LNG from DOMAC on a spot basis
when prices are competitive with alternative supplies. DOMAC's affiliate,
Distrigas Corporation, imports the LNG from Algeria pursuant to agreements with
Sonatrach, the Algerian National Energy Company, through its wholly-owned
subsidiary Sonatrading Amsterdam B.V. The United States Department of Energy
("DOE") and FERC have granted the necessary approvals for the import, sale and
storage of LNG.
 
     The Company relies on supplemental supplies to meet firm sendout
requirements which are greater than its firm pipeline capacity entitlements. The
number of days that peak sendout can be maintained is limited by the capacity of
the Company's storage facilities for supplemental gas supplies and the rate at
which these supplies can be sent out, and subsequently replenished. Increased
deliveries of pipeline supplies have reduced the Company's dependence on more
costly supplemental supplies. The Company considers its peak day sendout
capability, based on its total supply resources, adequate to meet the
requirements of its customers.
 
     The Company owns or leases facilities which enable it to store the
equivalent of 4,000 MMCF of natural gas in liquid form as LNG and vaporize it
for use during periods of high demand. The inventory for these facilities is
provided by liquefaction of pipeline gas and from LNG purchased. The maximum
storage capacity of these facilities may be limited by various factors,
including maintenance and other operating considerations.
 
     In addition to LNG, the Company has the ability to use propane to meet its
demand requirements during periods of extreme cold weather. Propane can be mixed
with air and introduced, along with natural gas, into the gas distribution
system at a number of propane-air facilities owned by the Company.

</TABLE>
 
REGULATION AND RATES
 
     The Company's operations are subject to Massachusetts statutes applicable
to gas utilities. Rates, the territorial limit of the Company's service area,
issuance of securities, affiliated party transactions, purchase of gas and
pipeline safety regulations are regulated by the Department.
 
     The rates for gas service rendered by the Company are subject to approval
by, and are on file with, the Department. Gas operating revenues are recognized
when billed. No revenue is recorded for the amount of gas distributed to
customers which is unbilled at the end of a period. The Company has a cost of
gas adjustment clause which allows for the adjustment of billing rates for firm
gas sales to recover the cost of gas delivered to firm customers. For financial
reporting purposes, 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.
 
                                        3
<PAGE>   5
 
     On October 30, 1993, the Department allowed the Company an annual revenue
increase of $37,700,000, effective November 1, 1993, and also approved several
rate design changes that reduce the volatility of the Company's margins
attributable to weather. This was accomplished by increasing customer charges
and moving the recovery of certain local production and storage costs from base
rates to the cost of gas adjustment clause.
 
     Facility expansion is regulated by the Department. Municipal, state and
federal authorities have jurisdiction over the use of public ways, land and
waters for gas mains and other distribution facilities.
 
LICENSES AND FRANCHISES
 
     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. On February 7, 1989, the SEC issued a
proposed rule under the Act which would provide limits for non-utility related
diversification by intrastate public utility holding companies, such as Eastern,
that are exempt under the Act. Since its proposal in 1989, the SEC has taken no
action with respect to this proposed rule. Eastern and the Company cannot
predict whether this proposed rule will be adopted or whether it will affect
their exemption under the Act.
 
     Except as set forth above, there are no patents, trademarks, licenses or
concessions that are important to the business of the Company.
 
COMPETITION AND MARKETING
 
     The Company competes with fuel oil and electricity and other supplies of
gas for residential, commercial and industrial uses. The Company's marketing
efforts continue to benefit from growing customer awareness of natural gas as a
safe, reliable, economical and environmentally sound fuel. Customer recognition
that the use of gas improves overall air quality, reduces pollutants and
eliminates on-site fuel storage problems has become increasingly significant.
 
     The Company added annual firm sales of approximately 2,443 MMCF in 1993. In
the commercial and industrial markets, where the Company has a 22% market share
in its service territory, a degree of penetration which is approximately half
that of the United States commercial and industrial market share, considerable
growth opportunities exist. In 1993, the Company added new firm annual load of
1,812 MMCF in these markets. Increasing environmental regulation of emissions
should provide additional opportunities in the commercial and industrial
markets. The Company has identified several industrial facilities that must file
compliance plans under these regulations by April 1, 1994.
 
     Approximately 4,391 residential customers converted to gas for central
heating last year. Despite lower oil prices, the Company expects continued
strong activity in the residential conversion market. Approximately 46% of the
Company's existing customers do not use gas for central heating. The Company
plans on targeting this group as well as electrically-heated residential
complexes with special programs to encourage the conversion to natural gas.
 
     FERC Order No. 636 and other regulatory changes have increased the
potential for competition among existing and new suppliers of natural gas in the
Company's service area, particularly in large commercial and industrial markets
(see "Gas Supply"). The Company believes it is well positioned to respond to
such sales competition. The Company received approval from the Department to
file contracts designed to compete with non-captive commercial and industrial
customers with alternative energy options. This provides for an expedited
approval process and enhances the Company's ability to negotiate sales
agreements that reflect competitive market conditions. In June 1992, FERC
granted the Company authority to make sales for resale in interstate commerce
under the terms of a blanket marketing certificate. This additional sales
authority allows the Company to maximize the use of its supply entitlements,
thereby minimizing the cost of gas to firm customers and making its sales rates
more competitive. The Company is also well positioned to provide transportation
service to customers who may engage in direct purchases of natural gas from
other suppliers under firm and interruptible transportation tariffs approved by
the Department. The rate design changes
 
                                        4
<PAGE>   6
 
approved by the Department in the October 30, 1993 rate order provide for margin
neutrality regardless of the customer's decision to purchase gas directly from
the Company or purchase third-party gas for transportation on the Company's
distribution system.
 
     The Company continues to pursue market opportunities in natural gas-powered
vehicles. The recent passage of The National Energy Policy Act, as well as the
Clean Air Act Amendments of 1990, both of which mandate the use of alternative
fuel vehicles by the mid-1990's by certain commercial fleets, have enhanced
opportunities in this market. The Company has initiated a number of programs
demonstrating the environmental and operating advantages of natural gas
vehicles. The Company's marketing activities include the installation of two
Company-owned fueling stations, conversion of 92 Company vehicles, and
establishment of pilot programs with a number of large fleet operators to
demonstrate the advantages of choosing natural gas to meet alternative fuel
vehicle requirements.
 
     Other new markets, such as air conditioning, cogeneration and desiccant
dehumidification continue to develop as new technologies emerge.
 
ENVIRONMENTAL REGULATION
 
     The Company is subject to local, state and federal environmental regulation
of its operations and properties. The Company is working with the Massachusetts
Department of Environmental Protection ("DEP") to determine the environmental
impact, if any, of by-products associated with 13 former manufactured gas plant
("MGP") properties which the Company currently owns and for which the Company
may be potentially responsible. The Company is currently assessing seven of
these properties pursuant to applicable DEP procedures. The Company expects to
spend approximately $1 million in assessing these properties in 1994 and expects
similar expenditures for site assessment for the next several years as other
properties are investigated. Since the DEP has not yet approved a remediation
plan for any Company site, the Company cannot reliably predict the potential
liability associated with final remediation of any of these properties. Company
experience to date indicates that assessment and remediation costs of at least
$18 million could be incurred over the next several years at these thirteen
properties, subject to possible contribution or the assumption of responsibility
by New England Electric System ("NEES") or one of its subsidiaries as discussed
below.
 
     Massachusetts Electric Company, a wholly-owned subsidiary of NEES, has
assumed responsibility for remediating a fourteenth property currently owned by
the Company (part of the site of gas manufacturing operations in Lynn,
Massachusetts) pursuant to the decision of the Court of Appeals for the First
Circuit in The John S. Boyd, Inc., et al. v. Boston Gas Company, et al, Civil
Action No. 89-575-T (May 26, 1993). The First Circuit found that NEES and its
subsidiaries, as the prior owners and operators of the Lynn MGP site, were
responsible for remediating the site and that the Company did not assume any
liability for environmental remediation when it acquired the property from NEES
in 1973. Of the thirteen other sites currently owned by the Company, ten were
acquired from NEES. Given substantial similarities between these acquisitions
and that involved in Boyd, it is not probable that the Company will have any
material exposure for environmental remediation at these ten sites.
 
     There are 23 other former MGP sites within the Company's service territory
which the Company does not currently own. The DEP has not issued a Notice of
Responsibility to the Company for any of these 23 sites. At this time, there is
substantial uncertainty as to whether the Company is responsible for remediating
any of these sites either because the Company never owned the site, the Company
does not have successor liability for contamination of the site by earlier
operators, or site conditions do not require remediation by the Company.
 
     By an order issued on May 25, 1990, the Department approved a settlement
agreement which provides for the recovery through the cost of gas adjustment
clause of all environmental response costs associated with former MGP sites over
separate, seven-year amortization periods without a return on the unamortized
balance. The settlement agreement also provides for no further investigation of
the prudency of any Massachusetts gas utility's past MGP operations.

EMPLOYEE RELATIONS
 
     As of December 31, 1993, the Company had 1,720 employees, 71% of whom were
organized in six local unions with which the Company has collective bargaining
agreements. In 1993, after a seventeen-week work stoppage, the Company entered
into a new six-year labor contract with the bargaining units which, among other
things, provides for annual general wage increases of approximately 4%, updates
work rules and changes health care coverage to a managed care program with cost
sharing.
 
ITEM 2.  PROPERTIES.
 
     The Company and Mass LNG own or lease 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, and Mass LNG leases and operates
one such facility in Lynn, Massachusetts, and a storage facility in Salem,
Massachusetts. In addition, the Company owns propane-air facilities at several
locations throughout its service territory.
 
     In addition to the properties described above, the Company owns or leases
several small buildings and miscellaneous parcels of land located throughout its
service area which are used for such purposes as storage, subsidiary operations
centers, district business offices and natural gas receiving stations.
 
     The Company's gas distribution system on December 31, 1993 included
approximately 5,700 miles of gas mains, 396,000 services and 519,000 active
customer meters.
 
     The Company's gas mains and services, as well as related equipment, are, in
general not on land owned in fee, being in part, in, under or over public ways,
land or water and, in part, upon or under private ways or other property not
owned by the Company, such occupation of public and private property being, in
general, 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. A portion of the utility properties and franchises of the Company are
pledged as security for the Company's First Mortgage Bonds.
 
     In 1993, the Company's expenditures on capital expansion and improvement
were $47.1 million. Capital expenditures were principally made for improvements
to the distribution system, for system expansion to meet customer demand and for
productivity enhancement.
 
ITEM 3.  LEGAL PROCEEDINGS.
 
     With the resolution of the John Boyd case discussed in Item 1 above, and
other than normal 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

ITEM 5.  MARKET FOR THE COMPANY'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, 1993. Dividends
on such common equity amounted to $8,998,219 and $7,712,760 for 1993 and 1992,
respectively. At December 31, 1993, under the most restrictive provision
limiting dividend payments in the Company's financing indentures, there were no
restrictions on retained earnings.
 
ITEM 6.  SELECTED FINANCIAL DATA.
 
     Not required.
 
ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS.
 
1993 COMPARED TO 1992
 
     Earnings available to common shareholders in 1993 of $18.0 million were
$9.3 million lower than the prior year. Earnings in 1992 reflect a one-time
increase of $7.2 million, as a result of a modification to the Company's gas
cost recovery mechanism approved by the Department in May 1992. The modification
shifted the recovery of a portion of pipeline gas costs from the non-heating
season to the heating season to more closely match revenues with costs incurred.
Excluding such modification, earnings year to year decreased $2.1 million. This
decline in earnings was primarily due to the seventeen week labor dispute and
increased depreciation and amortization expense. In addition, weather was 1.3%
warmer than normal and 4.5% warmer than 1992.
 
     Partially offsetting the above was a $5.0 million increase in net earnings
related to the rate increase granted the Company by the Department effective
November 1, 1993. The Department awarded the Company an annual revenue increase
of $37.7 million, or 6.3%. During 1993, the Company added annual firm sales of
approximately 2.4 BCF from the conversion of approximately 4,391 existing
non-heating residences to natural gas and the addition of new customers.
 
     Operating earnings of $49.0 million , excluding the 1992 operating earnings
impact of the change in the gas cost recovery mechanism of $11.6 million, were
$2.4 million lower than 1992. The increase in operating expenses was mainly due
to the work stoppage and its resultant impact on expenditure capitalization.
Depreciation and amortization expense increases in 1993 are principally the
result of continued investments in system replacement and expansion and
productivity programs. Year to year increases in property taxes also contributed
to the decline in operating earnings.
 
1992 COMPARED TO 1991
 
     Earnings available to common shareholders in 1992 of $27.3 million were 76%
higher than 1991 earnings of $15.5 million primarily due to more seasonable
weather and the modification to the Company's gas cost recovery mechanism
approved by the Department effective May 1, 1992. Since the change took effect
May 1, 1992, the Company recognized a one-time increase in earnings of $7.2
million; however, the modification has no impact on earnings over a 12 month
period. Excluding the modification to the gas cost recovery mechanism, earnings
year to year increased $4.6 million.
 
     More seasonal weather, following unusually warm weather conditions in 1990
and 1991, produced the most favorable impact on 1992 earnings, representing a
$9.1 million increase over 1991 results. 1992, which was 19% colder as compared
to 1991, resulted in an increase in firm gas sales of 7.3 BCF. Growth in the
firm customer base also contributed to the increase in earnings. During 1992,
the Company added annual firm sales of approximately 3.1 BCF from the conversion
of 4,690 existing non-heating residences to natural gas and the additional new
customers.
 
     Operating earnings, excluding the pre-tax impact of the change in the gas
cost recovery mechanism of $11.6 million, were $12.2 million higher than 1991
operating earnings of $39.3 million. Operating expense
 
                                        7
<PAGE>   9
increases were primarily the result of higher labor and system maintenance
costs. Depreciation and amortization expense increased in 1992 due to continued
investments related primarily to customer growth, system replacement and
productivity improvements. Interest expense increased in 1992 as compared to
1991 due to higher levels of average debt outstanding and reduced capitalized
interest.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     The Company maintains four committed lines of credit totaling $40.0
million. The Company also maintains various uncommitted lines of credit and
markets its own commercial paper. In addition, the Company may borrow up to
$45.0 million under Eastern's credit facilities.
 
     In accordance with the rate order issued by the Department effective
October 1, 1988, the Company funds all of its gas inventory through external
financing. The costs of such financing are recovered from customers through the
Company's cost of gas adjustment clause. Effective December 31, 1993, the
Company increased its credit capacity for fuel financing through the negotiation
of a credit agreement with a group of banks which provides for borrowing of up
to $90.0 million for the purpose of financing its inventory of gas supplies. The
Company's' capacity under the prior agreement was $60.0 million. (See Note 4 of
the Notes to Consolidated Financial Statements.)
 
     On May 12, 1993, the Company received from its shareholder, Eastern
Enterprises, a $20.0 million equity contribution, which was used to redeem $20.0
million of the Company's outstanding 9% Debentures, due 2001.
 
     On July 13, 1993, the Registrant selected a Final Term which is a Mandatory
Redemption Term with respect to its Variable Term Cumulative Preferred Stock,
Series A. The dividend rate during the Final Term is 6.421% per annum and
dividends are paid quarterly. The Final Term calls for 5% annual sinking fund
payments beginning on September 1, 1999, is non-callable for 10 years, and shall
end on September 1, 2018.
 
     The Company expects capital expenditures for 1994 to be approximately $53.0
million. Capital expenditures will be largely for improvements to the
distribution system, for system expansion to meet customer demand and for
productivity enhancement. The Company also expects to incur assessment and
remediation costs of approximately $1.0 million in 1994 associated with MGP
sites. Such costs are recoverable in rates as discussed more fully in Note 12 of
Notes to Consolidated Financial Statements.
 
     On October 30, 1993, the Department granted the Company an annual revenue
increase of $37.7 million effective November 1, 1993.
 
     In January 1994, the Company issued $36.0 million of Medium-term Notes
Series B, with a weighted average maturity of 24 years and coupon of 6.94%
pursuant to a $50.0 million shelf registration statement dated October 28, 1992
on file with the SEC.
 
     The Company believes that projected cash flow from operations, in
combination with currently available resources, is sufficient to meet 1994
capital expenditures and working capital requirements, normal debt repayments
and dividends to shareholders.

                       BOSTON GAS COMPANY AND SUBSIDIARY
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
(1)  ACCOUNTING POLICIES
 
     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--Post-Retirement 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.
 
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 3.98% in 1993, 3.80% in 1992 and 3.79% in
1991.
 
     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 requires the Company to adjust its rates
semiannually 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. The cost of gas adjustment
clause also recovers the amortization of all environmental response costs
associated with former manufactured gas plant ("MGP") sites and costs related to
the Company's various conservation and load management programs.
 
     In May of 1992, the Company modified the cost of gas adjustment clause
shifting a portion of pipeline gas costs from the non-heating to the heating
season in order to more closely match revenues with the related costs.
 
(3)  INCOME TAXES
 
     The Company is a member of an affiliated group of companies which files a
consolidated federal income tax return. The Company follows the policy,
established for the group, of providing for income taxes which would be payable
on a separate company basis. The Company's effective income tax rate was 38.4%
in 1993,

39.4% in 1992 and 36.2% in 1991. State taxes represent the majority, or 4.3%,
4.6% and 4.8% of the difference between the effective rate and the Federal
income tax rate for 1993, 1992 and 1991, respectively.

</TABLE>
 
     Effective January 1, 1992, the Company adopted Statement of Financial
Accounting Standards No. 109 ("SFAS 109"), "Accounting for Income Taxes." SFAS
109 requires adjustment of deferred tax assets and liabilities to reflect the
future tax consequences, at currently enacted rates, of items already reflected
in the financial statements. A regulatory asset of $1,880,000 was established
for the recovery of prepaid taxes established at the higher federal tax rates in
effect prior to 1988. In its most recent rate request proceeding, the Company
received permission to recover this amount over three years. A regulatory
liability of $6,144,000 was established for the tax benefit of unamortized
investment tax credits, which SFAS 109 requires to be treated as a temporary
difference. This benefit will be passed on to customers over the lives of
property giving rise to the investment credits, consistent with the 1986 Tax
Reform Act. About 38% of each of these items reflect a "gross-up" for taxes as
SFAS 109 eliminated net-of tax accounting for regulatory assets and liabilities.
The regulatory liability for excess deferred taxes being returned to customers
over a 30 year period pursuant to a 1988 rate order was similarly increased by
$4,445,000 upon the adoption of SFAS 109.
 
     The Revenue Reconciliation Act of 1993, enacted on August 10, 1993,
increased the statutory Federal income tax rate from 34% to 35%, retroactive to
January 1, 1993. The provision for income taxes in 1993 includes approximately
$300,000 for the impact of the rate change on current earnings. The effect of
the rate change on deferred tax requirements at January 1, 1993 is reflected in
the regulatory asset and liability established at the adoption of SFAS 109.

     During 1991, deferred income taxes were provided for significant timing
differences in the recognition of revenue and expenses for tax and financial
statement purposes. The principal component of the 1991 deferred provision was
$2,308,000 for accelerated depreciation, partially offset by a credit of
$1,021,000 for deferred gas costs.
 
     Investment tax credits are deferred and credited to income over the lives
of the property giving rise to such credits. The credit to income was
approximately $689,000 in 1993, $673,000 in 1992 and $692,000 in 1991.

     On October 28, 1992, the Company filed a Shelf registration covering the
issuance of up to $50,000,000 of additional Medium-Term Notes through December
31, 1994 for the financing of capital expenditures and the payment of related
obligations. In January 1994 the Company issued $36,000,000 of Medium-Term Notes
with maturities of 20 - 30 years and an average weighted interest rate of 6.94%.

     The terms of the various indentures referred to above, as supplemented,
provide that dividends may not be paid on common stock of the Company under
certain conditions. At December 31, 1993 there were no restrictions on retained
earnings available for payment of dividends.
 
Gas Inventory Financing
 
     Under the terms of the general rate order issued by the Department of
Public Utilities (the Department) effective October 1, 1988, the Company funds
all of its inventory of gas supplies through external sources. All costs related
to this funding are recoverable from its customers. The Company maintains a
credit agreement with a group of banks which provides for the borrowing of up to
$90,000,000 for the exclusive purpose of funding its inventory of gas supplies
or for backing commercial paper issued for the same purpose. The Company had
$59,297,000 and $48,631,000 of commercial paper outstanding at December 31, 1993
and 1992, respectively, for this purpose. 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 364 day revolving credit which may be converted to a
two-year term loan at the Company's option if the 364 day revolving credit is
not renewed by the banks. The Company may select interest rate alternatives
based on prime or Eurodollar rates. No borrowings were outstanding under this
agreement at December 31, 1993 and no borrowings were outstanding under the
prior $60,000,000 credit agreement at December 31, 1992.
 
Notes Payable
 
     The Company maintains four committed lines of credit totaling $40,000,000
which provide for interest at either prime rate or money market rates. The
Company pays facility fees related to these lines of credit. In addition, the
Company has various uncommitted lines of credit which provide for interest at
the federal funds, money market or prime rates. These lines of credit are used
for short-term borrowings. The Company had outstanding borrowings of
$106,300,000 and $53,332,000 in commercial paper and bank loans not related to
gas inventory financing at December 31, 1993 and 1992, respectively.

Eastern Borrowing Arrangement
 
     Eastern has a credit agreement with a group of banks which provides for the
borrowing by Eastern and its subsidiaries of up to $60,000,000 (of which the
Company may borrow up to $35,000,000) at any time through December 31, 1994,
with borrowings thereunder maturing not later than December 31, 1995. The
interest rate for such borrowings is the agent bank's prime rate, or at
Eastern's option, 1/4 of 1% over the agent bank's Eurodollar rate or 3/8 of 1%
over the agent bank's certificate of deposit rate. Eastern has the option until
December 31, 1994 to convert up to $25,000,000 of the total commitment to a
five-year term loan arrangement with the same interest rate provisions through
1994 and thereafter with interest of 1/8 of 1% over the agent bank's prime rate
or 5/8 of 1% over the agent bank's Eurodollar rate or 7/8 of 1% over the agent
bank's certificate of deposit rate. The credit agreement provides, among other
things, for a commitment fee of 1/4 of 1% on the first $50,000,000 unused
portion of the commitment and 3/16 of 1% on the unborrowed portion of the
commitment greater than $50,000,000.
 
     Eastern also has a $10,000,000 line of credit under which the Company is
entitled to borrow which provides for interest at the prime rate, or at
Eastern's option, rates tied to Eurodollar, certificate of deposit or money
market quotes.
 
(5)  VARIABLE TERM CUMULATIVE PREFERRED STOCK
 
     On July 13, 1993, the Company selected a Final Term which is a Mandatory
Redemption Term with respect to its Variable Term Cumulative Preferred Stock,
Series A. The dividend rate during the Final Term is 6.421% per annum and
dividends are paid quarterly. The Final Term calls for 5% annual sinking fund
payments beginning on September 1, 1999, is non-callable for 10 years, and shall
end on September 1, 2018.
 
(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").

(7)  POST-RETIREMENT 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.
 
     Effective January 1, 1991, the Company adopted Statement of Financial
Accounting Standards No. 106 ("SFAS 106"), "Employers' Accounting for
Post-Retirement Benefits Other Than Pensions," by immediately recognizing the
cumulative effect of the accounting change. SFAS 106 requires that the expected
cost of post-retirement benefits other than pensions be charged to expense
during the period that the employee renders service. As of the date of adoption,
the cumulative effect of the accounting change ("transition obligation") was,
$89,120,000. With approval by the Department, the Company has deferred the cost
of the transition obligation and the amount by which expense under SFAS 106
exceeds amounts currently included in rates. The 1993 rate order allows the
Company to phase in incremental costs associated with SFAS 106 over a four-year
period. Each year during the phase-in, the Company will file for an increase in
rates to reflect an additional increment of SFAS 106 costs. The difference
between the incremental annual amount allowed in rates during the phase-in
period and the SFAS 106 costs will be deferred as a regulatory asset with
carrying costs.

</TABLE>
 
     The Company established a 501(c)(9) Voluntary Employee Beneficiary
Association ("VEBA") Trust in 1991 to begin funding its post-retirement benefit
obligation for collectively bargained employees. The Company contributed
$5,000,000 in 1992 to the VEBA.
 
     The weighted average discount rate used in determining the accumulated
post-retirement benefit obligation was 7.5% in 1993 and 1992. A 12% and 15%
annual increase in the cost of covered health care benefits was assumed for 1993
and 1992, respectively. This rate of increase is assumed to drop gradually to 5%
after 7 years. A 1% increase in the assumed health care cost trend would have
increased the post-retirement benefit cost by $489,000 and $1,056,000 and the
accumulated post-retirement benefit obligation by $5,691,000 in 1993 and
$9,164,000 in 1992.
 
     In November 1992, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 112 ("SFAS 112"), "Employer's Accounting
for Postemployment Benefits", which establishes standards of financial
accounting and reporting for certain postemployment benefit obligations. The
adoption of SFAS 112 is not expected to have a material effect on the Company's
financial condition or results of operations. SFAS 112 is effective for fiscal
years beginning after December 15, 1993.
 
(8)  LEASES
 
     The Company and its subsidiary lease certain facilities and equipment under
long-term leases which expire on various dates through the year 2000. Total
rentals charged to income under all lease agreements were approximately
$7,663,000 in 1993, $6,939,000 in 1992 and $6,417,000 in 1991.

     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
income.

     The following methods and assumptions were used to estimate the fair value
disclosures for financial instruments:
 
  Cash and Short-term Investments
 
     The carrying amounts approximate fair value because of the short maturity
of those instruments.
 
  Short-term Debt
 
     The carrying amounts of the Company's short-term debt, including notes
payable and gas inventory financing, approximate their fair value.
 
  Long-term Debt
 
     The fair value of long-term debt is estimated based on currently quoted
market prices for similar types of borrowing arrangements.

     The Company paid Eastern $3,096,000 in 1993, $2,707,000 in 1992 and
$2,520,000 in 1991 for various legal, tax and corporate services rendered.

     Firm and non-firm sales to a single customer produced revenues totaling

and 3.5% of total revenues in 1993, 1992 and 1991, respectively.
 
(12)  ENVIRONMENTAL ISSUES
 
     The Company is subject to local, state and federal environmental regulation
of its operations and properties. The Company is working with the Massachusetts
Department of Environmental Protection ("DEP") to determine the environmental
impact, if any, of by-products associated with 13 former manufactured gas plant
("MGP") properties which the Company currently owns and for which the Company
may be potentially responsible. The Company is currently assessing seven of
these properties pursuant to applicable DEP procedures. The Company expects to
spend approximately $1 million in assessing these properties in 1994 and expects
similar expenditures for site assessment for the next several years as other
properties are investigated. Since the DEP has not yet approved a remediation
plan for any Company site, the Company cannot reliably predict the potential
liability associated with final remediation of any of these properties. Company
experience to date indicates that assessment and remediation costs of at least
$18 million could be incurred over the next several years at these thirteen
properties, subject to possible contribution or the assumption of responsibility
by New England Electric System ("NEES") or one of its subsidiaries as discussed
below.
 
     Massachusetts Electric Company, a wholly-owned subsidiary of NEES, has
assumed responsibility for remediating a fourteenth property currently owned by
the Company (part of the site of gas manufacturing operations in Lynn,
Massachusetts) pursuant to the decision of the Court of Appeals for the First
Circuit in The John S. Boyd, Inc., et al. v. Boston Gas Company, et al, Civil
Action No. 89-575-T (May 26, 1993). The First Circuit found that NEES and its
subsidiaries, as the prior owners and operators of the Lynn MGP site, were
responsible for remediating the site and that the Company did not assume any
liability for environmental remediation when it acquired the property from NEES
in 1973. Of the 13 other sites currently owned by the Company, 10 were acquired
from NEES. Given substantial similarities between these acquisitions and that
involved in Boyd, it is not probable that the Company will have any material
exposure for environmental remediation at these 10 sites.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
(12)  ENVIRONMENTAL ISSUES (CONTINUED)
     There are 23 other former MGP sites within the Company's service territory
which the Company does not currently own. The DEP has not issued a Notice of
Responsibility to the Company for any of these 23 sites. At this time, there is
substantial uncertainty as to whether the Company is responsible for remediating
any of these sites either because the Company never owned the site, the Company
does not have successor liability for contamination of the site by earlier
operators, or site conditions do not require remediation by the Company.
 
     By an order issued on May 25, 1990, the Department approved a settlement
agreement which provides for the recovery through the cost of gas adjustment
clause of all environmental response costs associated with former MGP sites over
separate, seven-year amortization periods without a return on the unamoritized
balance. The settlement agreement also provides for no further investigation of
the prudency of any Massachusetts gas utility's past MGP operations.
 
(13)  PIPELINE TRANSITION COSTS
 
     Pursuant to Federal Energy Regulatory Commission ("FERC") Order No. 636,
pipelines will be allowed 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.
 
     The Company's obligation for transition costs is $30.6 million and it has
recorded this amount less actual billings at December 31, 1993 of $6.3 million
as a liability in the accompanying consolidated balance sheet. As pipelines
continue to incur and file for recovery of transition costs, the Company's
obligation may increase.
 
     The Company's obligation to Tennessee for transition costs is $12.0
million, based on filings by Tennessee at FERC. Payments to Tennessee for such
costs commenced in October 1993. The Company's obligations to Texas Eastern and
Algonquin for transition costs is $18.6 million, based on filings by Texas
Eastern and Algonquin at FERC. Payments to Texas Eastern and Algonquin began in
July 1993.
 
     The Department has allowed recovery of the Company's transition costs
liability over a five-year period commencing in May 1994. Accordingly, the
Company has recorded a regulatory asset equivalent to the liability established
at December 31, 1993.

                    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, 1993 and 1992, and the related
consolidated statements of earnings, retained earnings and cash flows for each
of the three years in the period ended December 31, 1993. These 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
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 financial statements referred to above present fairly,
in all material respects, the financial position of Boston Gas Company and
subsidiary as of December 31, 1993 and 1992 and the results of their operations
and their cash flows for each of the three years in the period ended December
31, 1993, 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 and schedules 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.

     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.

          Any portions of this Service Agreement necessary to correct
     or cash-out imbalances under this Service Agreement as required
     by the General Terms and Conditions of Pipeline's FERC Gas
     Tariff, Volume No. 1, shall survive the other parts of this
     Service Agreement until such time as such balancing has been
     accomplished.

                                 RATE SCHEDULE

     Commission, and as same may hereafter be legally amended or
     superseded.

          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 CDS,  (b)  Pipeline's

      or   (c)   any  provision  of  the  General  Terms  and  Conditions
      applicable to Rate Schedule CDS.   Notwithstanding the foregoing,
      Customer does not agree that Pipeline shall have the unilateral

      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  in  Article I,  to  change  the  term  of    the

      Receipt  specified  in  Article  IV,  to  change  the  Point(s)   of

      not waive any rights it may have with respect to such filings.

      shall  conform to the quality specifications  set  forth  in
      Section 5 of Pipeline's 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.  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

                     -----------------------------------

           This Agreement ("Agreement") is made and entered into this 1st day of
           June, 1993, by and between Algonquin Gas Transmission Company,
           a Delaware Corporation (herein called "Algonquin"), and Boston Gas

           In consideration of the premises and of the mutual covenants herein
           contained, the parties do agree as follows:

                                   ARTICLE I

           1.1 Subject to the terms, conditions and limitations hereof and of

               from or for the account of Customer for transportation on a firm
               basis quantities of natural gas tendered by Customer on any day

               not tender without the prior consent of Algonquin, at any Point
               of Receipt on any day a quantity of natural gas in excess of the
               applicable Maximum Daily Receipt Obligation for such Point of
               Receipt plus the applicable Fuel Reimbursement Quantity; and
               provided further that Customer shall not tender at all Point(s)
               of Receipt on any day or in any year a cumulative quantity of
               natural gas, without the prior consent of Algonquin, in excess
               of the following quantities of natural gas plus the applicable
               Fuel Reimbursement Quantities:

                               TERM OF AGREEMENT

           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, 1996 ("Primary Term") and shall remain in

               for service hereunder and such failure continues for thirty days
               after payment is due; provided Algonquin gives ten 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 Algonquin of such outstanding bill; provided that 
               Algonquin shall not be entitled to terminate service pending the
               resolution of a disputed bill if Customer complies with the 
               billing dispute procedure currently on file  in Algonquin's 
               tariff.

                                   ARTICLE III

               Commission and as the same may be hereafter revised or changed. 
               The rate to be charged Customer for transportation hereunder 
               shall not be more than the maximum rate under Rate Schedule 
               AFT-1, nor less than the minimum rate under Rate Schedule AFT-1.

               regulatory authorities for such adjustment of Algonquin's
               existing FERC Gas Tariff as may be found necessary to assure
               that the provisions in (a), (b), or (c) above are just and
               reasonable.

                       PRELIMINARY MATTERS
                       -------------------

     The Company desires to request that Loans be made during the
three hundred sixty-four (364) day period commencing on the
Effective Date and ending on the Revolving Credit Termination
Date in an aggregate amount not to exceed the Aggregate
Commitments. Loans which are outstanding on the Revolving Credit
Termination Date are to begin amortizing as required under
paragraph 2.5(b). The Revolving Credit Termination Date is
subject to being extended for successive one-year periods
pursuant to paragraph 2.14. For the purpose of computing interest
on the Loans, Loans may be requested by the Company as Alternate
Base Rate Loans or Eurodollar Rate Loans (each, a Type of Loan)
and shall bear interest at the Alternate Base Rate or Eurodollar
Rate plus the Applicable Margin with respect to each thereof as
provided in paragraph 2.7.  During the period from the Revolving
Credit Termination Date to and including the Termination Date the
Company may not effect borrowings which would increase the
outstanding principal balance of Loans hereunder, but may convert
and continue Loans as provided in paragraph 2.6.


2.   AMOUNT AND TERMS OF LOANS.
     -------------------------

     2.1  LOANS.  Subject to the terms and conditions of this Agreement, 
each Bank severally agrees to make Loans to the Company from time to time
on and after the Effective Date to, but excluding, the Revolving
Credit Termination Date, provided that the aggregate unpaid
principal amount of all Loans due to each Bank at any one time
shall not exceed an amount equal to such Bank's Commitment, and
provided further that the aggregate unpaid principal amount of
the Loans at any one time outstanding shall not exceed the lesser
of (i) the Aggregate Commitments and (ii) the aggregate
outstanding principal balance of all Loans permitted to be
outstanding hereunder after giving effect to the mandatory
prepayments required to be made under paragraph 2.5(b). During
the period from the Effective Date to the Revolving Credit
Termination Date, the Company may borrow, repay and reborrow
hereunder, and may convert all or any part of the Loans from one
Type to another Type or continue all or any part of the Loans as
the same Type in accordance with and subject to the terms and
provisions hereof. In the event the Company elects to extend the
scheduled maturity of the Loans in accordance with paragraph






<PAGE>   14

                            -9-


2.15 hereof, during the period from and after the Revolving
Credit Termination Date to the Termination Date, the Company may
prepay the Loans and may convert all or any part of the Loans
from one Type to Loans of another Type or continue all or any
part of the Loans as the same Type, all in accordance with and
subject to the terms and provisions hereof.

     2.2  PROCEDURE FOR BORROWINGS.  The Company may effect a Borrowing 
on any Business Day occurring on or after the Effective Date by giving 
the Agent an irrevocable telephonic (to be promptly confirmed in writing) 
or written notice of borrowing (each, a "Borrowing Request" in the form of
Exhibit B) (which Borrowing Request must be received by the Agent
(a) prior to 10:00 A.M., Boston time, two Business Days prior to
the requested Borrowing Date, if the Company is requesting that
Eurodollar Rate Loans be made as part of such Borrowing, and (b)
prior to 10:00 A.M., Boston time, one Business Day prior to the
requested Borrowing Date, if the Company is requesting that
Alternate Base Rate Loans be made as part of such Borrowing),
specifying (i) the amount to be borrowed, (ii) the requested
Borrowing Date, (iii) whether such Borrowing is to consist of,
Eurodollar Rate Loans, Alternate Base Rate Loans, or a
combination thereof, and (iv) if the Loans are to be Eurodollar
Rate Loans, the length of the initial Interest Period for each
thereof. Each Borrowing shall be in an aggregate principal amount
equal to or greater than $1,000,000 or, if less, the undrawn
balance of the Aggregate Commitments. The principal amount of
each Bank's Loan made on a Borrowing Date shall be in an amount
equal to such Bank's Commitment Percentage of the Loans made on
such Borrowing Date. Subject to the provisions of paragraphs 2.7
and 2.8, Loans may be Alternate Base Rate Loans or Eurodollar
Rate Loans, or any combination thereof. Upon receipt of each
Borrowing Request from the Company, the Agent shall promptly
notify each Bank thereof (such notice to be promptly confirmed in
writing). Each Bank will make the amount of its Commitment
Percentage of each Borrowing available to the Agent for the
account of the Company at the office of the Agent set forth in
paragraph 11.1, in the case of Eurodollar Rate Loans, not later
than 12:00 noon, Boston time, and in the case of Alternate Base
Rate Loans, not later than 11:00 A.M., Boston time, on the
Borrowing Date requested by the Company, in funds immediately
available to the Agent at such office. Amounts so made available
to the Agent on a Borrowing Date will, subject to the
satisfaction of the terms and conditions of this Agreement as
determined by the Agent, be made available on such date to the
Company by the Agent at the office of the Agent specified in
paragraph 11.1 by crediting the account of the Company on the
books of such office with the aggregate of said amounts, in like
funds as received by the Agent. Unless the Agent shall have
received prior notice from a Bank (by telephone or otherwise,
such notice to be promptly confirmed by telex, telecopy or other
writing) that such Bank will not make available to the Agent such
Bank's pro rata share of the Loans requested by the Company, the
Agent may assume that such Bank has made such share available to
the Agent on such Borrowing Date in accordance with this
paragraph, provided that such Bank received notice of the
proposed borrowing from the Agent, and the Agent may, in reliance
upon such assumption, make available to the Company on such
Borrowing Date a corresponding amount.  If and to the extent such
Bank shall not have so made such pro rata share available to the
Agent on such Borrowing Date, such Bank shall pay to the Agent on
demand an amount equal to the product of (i) the average computed
for the period referred to in clause (iii) below, of the weighted
average interest rate paid by the Agent for federal funds
acquired by the Agent during each day included

<PAGE>   15

in such period, TIMES (ii) the amount of such Bank's Commitment Percentage of
such Loans, TIMES (iii) a fraction, the numerator of which is the number of
days that elapse from and including such Borrowing Date to the date on which
the amount of such Bank's Commitment Percentage of such Loans shall become
immediately available to the Agent, and the denominator of which is 365.  If
such Bank shall pay to the Agent such amount, such amount so paid shall
constitute such Bank's Loan as part of such Loans for purposes of this
Agreement, which Loan shall be deemed to have been made by such Bank on the
date such amount is so paid, but without prejudice to the Company's rights
against such Bank.  If and to the extent such Bank shall not have so made such
pro rata share available to the Agent within three days following such
Borrowing Date, the Company shall pay to the Agent forthwith on demand (but
without duplication) an amount equal to such Bank's Commitment Percentage of
such Loans, together with interest thereon for each day from the date such
amount is made available to the Company until the date such amount is paid to
the Agent, at the applicable interest rate for such Loans as set forth in
paragraph 2.7. Such payment by the Company, however, shall be without prejudice
to its rights against such Bank.

        2.3  REVOLVING CREDIT NOTES. Loans made by each Bank shall be evidenced
by a promissory note of the Company, substantially in the form of Exhibit D,
with appropriate insertions therein (as endorsed and as amended or otherwise
modified from time to time, a "Revolving Credit Note" and, collectively, the
"Revolving Credit Notes"), payable to the order of such Bank and representing
the obligation of the Company to pay the aggregate unpaid principal amount of
all Loans made by such Bank, with interest thereon as prescribed or determined
herein. Each Bank is hereby authorized to record the date and amount of each
Loan made by such Bank and the other information applicable thereto, and each
payment or prepayment of principal of, such Loan, on the applicable grid (and
any continuations thereof) annexed to and constituting a part of its Revolving
Credit Note. No failure to so record or any error in so recording shall affect
the obligation of the Company to repay such Loans, with interest thereon, as
herein provided. Each Revolving Credit Note shall (a) be dated the date the
initial Loans are made, (b) be stated to mature on the Revolving Credit
Termination Date, and (c) bear interest for the period from and including the
date thereof on the unpaid principal amount thereof from time to time
outstanding at the applicable interest rate per annum determined as provided
herein.

     2.4  VOLUNTARY REDUCTIONS OF THE AGGREGATE COMMITMENTS; TERMINATION.

        (A)  VOLUNTARY REDUCTIONS. During the period from the Effective Date to
the Revolving Credit Termination Date, the Company shall have the right, upon
at least two Business Days' prior written notice to the Agent, to reduce
permanently the Aggregate Commitments in whole at any time, or in part from
time to time, without premium or penalty, provided that (i) each partial
reduction of the Aggregate Commitments shall be in an amount equal to at least
$1,000,000, or such amount plus a whole multiple of $500,000, and (ii) the
Aggregate Commitments shall not be reduced to an amount less than the aggregate
principal balance of Loans outstanding on the date of such reduction (after
giving effect to reductions in such balance made on such date). Upon the
Aggregate Commitments being permanently reduced to zero prior to the Revolving
Credit Termination Date and upon payment in full of the Loans





<PAGE>   16

                              -11-


and all other sums due hereunder and under the Revolving Credit
Notes, or upon payment in full of all sums due hereunder and
under the Term Notes after the Revolving Credit Termination Date,
this Agreement shall be deemed terminated, except to the extent
that any provisions hereof expressly survive such payment.

     (B)  GENERAL. Reductions of the Aggregate Commitments under
clause (a) above shall reduce each Bank's Commitment pro rata
according to the Commitment Percentage of such Bank. The Agent
shall promptly notify each Bank of each reduction in the
Aggregate Commitments under clause (a) above upon its receipt of
notice thereof, and remit to each Bank its pro rata share of any
accompanying prepayments of the Loans according to the
outstanding principal balance of the Loans. Simultaneously with
each reduction of the Aggregate Commitments under this paragraph
2.4, the Company shall prepay the Loans in the amount, if any, by
which the aggregate unpaid principal balance of the Loans exceeds
the amount of the Aggregate Commitments as so reduced.

     If any prepayment is made under this paragraph 2.4 with
respect to any Eurodollar Rate Loans, in whole or in part, prior
to the last day of the applicable Interest Period with respect
thereto, the Company agrees that it shall indemnify the Banks in
accordance with paragraph 2.11. After giving effect to any
prepayment with respect to Eurodollar Rate Loans, no Eurodollar
Rate Loans made (whether as a result of Borrowing or a
conversion) on the same date and having the same Interest Period
shall be outstanding in an aggregate principal amount of less
than $1,000,000.

     2.5  PREPAYMENTS AND PAYMENT OF LOANS.

     (A)  VOLUNTARY PREPAYMENTS. The Company may, at its option,
prepay Loans in whole or in part, without premium or penalty,
subject to its obligation to indemnify provided in paragraph 2.11
(in the case of Eurodollar Rate Loans), at any time and from time
to time upon at least one Business Day's prior irrevocable
written notice to the Agent, specifying the amount to be prepaid,
and the date and amount of prepayment. Upon receipt of such
notice, the Agent shall promptly notify each Bank thereof. Any
such notice shall be irrevocable and the amount specified in such
notice shall be due and payable on the date specified therein,
together with accrued interest to the date of such payment on the
amount being prepaid. Prepayments shall be in an aggregate
principal amount of at least $1,000,000 or, if less, the
outstanding principal balance of the Notes, provided, however,
that after giving effect to any such prepayment, no Eurodollar
Rate Loans made (whether as the result of Borrowing or a
conversion) on the same date and having the same Interest Period
shall be outstanding in an aggregate principal amount of less
than $1,000,000.

     (B)  MANDATORY REPAYMENT.  On the Revolving Credit
Termination Date or, in the event that the Company elects to
extend the scheduled maturity in accordance with the terms of
paragraph 2.15 hereof, the Termination Date, the Company shall
repay in full the aggregate principal balance of all Loans






<PAGE>   17

                            -12-


outstanding on such date, together with accrued interest on such
amount to such date and any Facility Fees, Agent's Fees or other
amounts owing hereunder or under the Term Notes.

     2.6  CONVERSION OPTIONS.

     (A)  CONVERSION.  The Company may elect from time to time to
convert Eurodollar Rate Loans to Alternate Base Rate Loans by
giving the Agent at least one Business Day's prior notice of such
election, specifying the amount to be so converted, provided,
that any such conversion of Eurodollar Rate Loans shall only be
made on the last day of the Interest Period applicable thereto.
In addition, in the absence of an Event of Default, the Company
may elect from time to time to convert Alternate Base Rate Loans
to Eurodollar Rate Loans, by giving the Agent at least two
Business Day's prior irrevocable notice of such election,
specifying the amount to be so converted and the Interest Period
selected, provided that any such conversion of Alternate Base
Rate Loans to Eurodollar Rate Loans shall only be made on a
Business Day.  The Agent shall promptly provide the Banks with
notice of any such election. Loans may be converted pursuant to
this paragraph 2.6, in whole or in part, provided that
conversions of Alternate Base Rate Loans to Eurodollar Rate Loans
or Eurodollar Rate Loans to Alternate Base Rate Loans shall be in
an aggregate principal amount of at least $1,000,000.  After
giving effect to any such conversion, no Eurodollar Rate Loans
made (whether as the result of a borrowing or a conversion) on
the same date and having the same Interest Period shall be
outstanding in an aggregate principal amount of less than
$1,000,000.  A conversion of a Loan in accordance with this
paragraph 2.6 shall not require the Company to comply with the
conditions to Borrowing set forth in paragraph 6.

     (B)  CONTINUATION.  Any Eurodollar Rate Loans may be
continued as such upon the expiration of any Interest Period with
respect thereto by the Company's giving irrevocable written
notice to the Agent of its intention to do so two Business Days
prior to the last day of such Interest Period, specifying the new
Interest Period therefor, provided that (i) if the Company shall
fail to give notice as provided above, the relevant Eurodollar
Rate Loan shall convert to an Alternate Base Rate Loan
immediately upon the expiration of the then current Interest
Period with respect thereto, (ii) any Eurodollar Rate Loans that
are being continued as such shall be in an aggregate principal
amount of at least $1,000,000 and (iii) no Eurodollar Rate Loans
may be continued as such when any Event of Default has occurred
and is continuing, but shall be automatically converted to an
Alternate Base Rate Loan on the last day of the Interest Period
with respect thereto during which the Agent obtained knowledge of
such Event of Default.  The Agent shall notify the Banks promptly
upon obtaining knowledge that an automatic conversion will occur
pursuant to clause (iii) hereof.

     2.7  INTEREST RATE AND PAYMENT DATES FOR LOANS.

     (A)  INTEREST RATES FOR LOANS PRIOR TO MATURITY. During each
period set forth on Exhibit B hereto, (i) Loans made as Alternate
Base Rate Loans shall bear interest for the period from and
including the date thereof, or, in the case of a Loan that has
been converted from a Eurodollar Rate Loan, from the Conversion
Date thereof, until maturity or until converted into Eurodollar
Rate Loans, on the unpaid principal amount thereof at the
Alternate Base Rate plus the Applicable Margin for such period
based on the Debt Rating of the Company, and (ii) Loans

Interest Period with respect thereto on the unpaid principal
amount thereof at the applicable rate of interest per annum based
on the Eurodollar Rate for each such Interest Period plus the
Applicable Margin for such period based on the Debt Rating of the
Company, provided that if the Company has no Debt Rating, the
Applicable Margin shall be the highest rate per annum applicable
to such Loans during the relevant period.  Any change in the
Applicable Margin with respect to any Loans resulting from a
change in the Debt Rating of the Company shall be effective as of
the opening of business on the day of the change in the Debt
Rating of the Company.

     (B)  OVERDUE AMOUNTS. If any amounts payable hereunder shall
not be paid when due (whether at the stated maturity thereof, by
acceleration, notice of intention to prepay or otherwise), such
overdue amounts shall bear interest payable on demand at a rate
per annum equal to 2% above the sum of the Alternate Base Rate
plus the Applicable Margin, if any, for Alternate Base Rate Loans
at such time from the date of such nonpayment until paid in full,
and whether before or after the entry of any judgment thereon,
provided that (i) each such Loan outstanding as a Eurodollar Rate
Loan shall bear interest payable on demand at a rate per annum
equal to 2% above the sum of the Eurodollar Rate plus the
Applicable Margin for such Eurodollar Rate Loan at such time,
from the date of such nonpayment until the end of the Interest
Period with respect thereto, and whether before or after the
entry of any judgment thereon.

     (C)  GENERAL. Interest on the Loans shall be payable in
arrears on each Interest Payment Date and upon payment (including
prepayment) in full thereof; provided, however, that after an
Event of Default has occurred and is continuing, interest on all
Loans shall be payable on demand made from time to time. At no
time shall the interest rate payable on the Loans, together with
the Agent's Fees, the Facility Fee and all other fees and amounts
payable hereunder and under the Notes, to the extent that any of
the same are construed to constitute interest, exceed the maximum
rate of interest permitted by law. The Company acknowledges that
to the extent interest payable on the Loans is based upon the
Alternate Base Rate, such Rate is only one of the bases for
computing interest on loans made by the Banks, and by basing
interest payable upon the Loans upon the Alternate Base Rate, the
Banks have not committed to charge, and the Company has not in
any way bargained for, interest based on a lower or the lowest
rate at which the Banks may now or in the future make loans to
other borrowers.

     2.8  SUBSTITUTED INTEREST RATE.  In the event that the Agent 
shall have reasonably determined in good faith (which determination 
shall be conclusive and binding upon the Company) that by reason of 
circumstances affecting the London interbank eurodollar market, (i) 
either adequate and reasonable means do not exist for ascertaining a
Eurodollar Rate applicable pursuant to paragraph 2.7(a), or (ii)
any Bank shall have notified the Agent that it has reasonably
determined in good faith (which determination shall be conclusive
and binding on the Company) that the Eurodollar Rate will not
adequately and fairly reflect the cost to such Bank of making or
maintaining its funding of a Eurodollar Rate Loan with respect to
(a) a proposed Loan that the Company has requested be made as a
Eurodollar Rate Loan, or (b) a Eurodollar Rate Loan that will
result from the requested conversion of any Loan into a
Eurodollar Rate Loan (any such Loan being herein called an
"AFFECTED LOAN"), the Agent shall promptly notify the Company
and





<PAGE>   19

                            -14-


the Banks (by telephone or otherwise) of such determination no
later than 10:00 A.M. (Boston time) one Business Day prior to the
requested Borrowing Date for such Affected Loan, or the requested
Conversion Date of such Loan, as the case may be. If the Agent
shall give such notice, the Company may by no later than 11:00
A.M. (Boston time) on the same Business Day, (i) cancel the
Borrowing Request with respect to such Affected Loan or request
that such Affected Loan be made as an Alternate Base Rate Loan or
(ii) cancel its request to convert to an Affected Loan or request
that any Loan that was to have been converted to an Affected Loan
be converted to an Alternate Base Rate Loan.  Until such notice
has been withdrawn by the Agent (by notice to the Company
promptly upon the Agent having been notified by such Bank that
circumstances would no longer render any Loan an Affected Loan)
no further Affected Loans shall be made and Company shall not
have the right to convert any Loan to an Affected Loan.

     2.9  ILLEGALITY.  Notwithstanding any provision hereof to the 
contrary, if any change in any law, regulation, treaty or directive, 
or in the interpretation or application thereof, shall make it 
unlawful for any Bank to make or maintain Eurodollar Rate Loans as
contemplated by this Agreement, (a) the commitment of such Bank
hereunder to make Eurodollar Rate Loans or to convert Alternate
Base Rate Loans to Eurodollar Rate Loans or to continue
Eurodollar Rate Loans as such shall forthwith be suspended and
(b) such Bank's Loans then outstanding as Eurodollar Rate Loans
shall be converted to Alternate Base Rate Loans on the last day
of the then current Interest Period applicable thereto, or within
such earlier period as required by law. If the commitment of any
Bank with respect to Eurodollar Rate Loans is suspended pursuant
to this paragraph 2.9 and it shall once again become legal for
such Bank to make or maintain its funding of Eurodollar Rate
Loans, such Bank's commitment to make or maintain such Eurodollar
Rate Loans shall be reinstated. Each Bank agrees to promptly
notify the Company and the Agent upon learning of any change
referred to above, as well as of any reinstatement of its ability
to make and maintain Eurodollar Rate Loans as contemplated by
this Agreement.

     2.10 INCREASED COSTS.  In the event that any change in 
any law, regulation, treaty or directive or in the interpretation 
or application thereof by any Governmental Body charged with the 
administration thereof or compliance by any Bank with any request 
or directive from any central bank or other Governmental Body:

         (i)   subjects any Bank to any tax of any kind whatsoever
     with respect to any Eurodollar Rate Loan or its obligations
     under this Agreement to make Eurodollar Rate Loans, or
     changes the basis of taxation of payments to such Bank of
     principal, interest or any other amount payable hereunder in
     respect of its Eurodollar Rate Loans (except for imposition
     of, or change in the rate of, tax on the overall net income
     of such Bank);

         (ii)  imposes, modifies or makes applicable any reserve,
     special deposit, compulsory loan, assessment or similar
     requirement against assets held by, or deposits of, or
     advances or loans by, or other credit committed or extended
     by, or any other acquisition of funds by, any office of such
     Bank in respect of its Eurodollar Rate Loans which is not
     otherwise included in the determination of a Eurodollar
     Rate; or







<PAGE>   20

                            -15-



         (iii) imposes on such Bank any other condition with
     respect to Loans hereunder or the Commitments;

and the result of any of the foregoing is to increase the cost to
such Bank of making, renewing, converting or maintaining its
Eurodollar Rate Loans, or to reduce any amount receivable in
respect of its Eurodollar Rate Loans, then, in any such case, the
Company shall promptly pay to such Bank, upon its demand, any
additional amounts necessary to compensate such Bank for such
additional cost or reduction in such amount receivable. A
statement setting forth the calculations of any additional
amounts payable pursuant to the foregoing sentence submitted by a
Bank to the Company shall be presumed to be correct absent
manifest error.


     2.11 INDEMNITY.  Notwithstanding anything contained herein to 
the contrary, if the Company shall fail to borrow on a Borrowing Date 
after it shall have given a Borrowing Request, to the extent only that
such Borrowing Request includes Eurodollar Rate Loans, or if the
right of the Company to have Eurodollar Rate Loans outstanding
hereunder shall be suspended or terminated in accordance with the
provisions of this Agreement prior to the last day of the
Interest Period applicable thereto, or if,  while a Eurodollar
Rate Loan is outstanding, any repayment or prepayment of the
principal amount of such Eurodollar Rate Loan is made for any
reason (including, without limitation, as a result of
acceleration or illegality) on a date which is prior to the last
day of the Interest Period applicable thereto, the Company agrees
to indemnify each Bank against, and to pay on demand directly to
such Bank, an amount, if greater than zero, equal to (i):

                         A x (B - C) x  D
                                       ---
                                       365
where:

          "A" equals the Affected Principal Amount;

          "B" equals the Eurodollar Rate (expressed as
          a decimal), as the case may be, applicable to
          such Eurodollar Rate Loan;

          "C" equals the applicable Eurodollar Rate
          (expressed as a decimal), as the case may be,
          in effect on the date of such failure to
          borrow, termination, prepayment or repayment,
          based on the applicable rates offered or bid,
          as the case may be, on such date (or, if no
          such rate is determinable on such date, the
          rate or rates offered or bid, as the case may
          be, determinable on the date closest
          thereto), for deposits in an amount equal
          approximately to the Affected Principal
          Amount with an Interest Period equal
          approximately to the period commencing on the
          first day of such Remaining Interest Period
          and ending on the last day of such Remaining
          Interest Period or ending on the last day of
          the







<PAGE>   21

                          -16-


          applicable Interest Payment Period, as the
          case may be, as determined by the Bank;

          "D" equals the number of days from and
          including the first day of the Remaining
          Interest Period to but excluding the last day
          of such Remaining Interest Payment Period;

and (ii) any other out-of-pocket loss or expense (including any
internal processing charge customarily charged by such Bank)
suffered by such Bank in liquidating deposits prior to maturity
in amounts which correspond to the proposed borrowing, prepayment
or repayment. The determination by each Bank of the amount of any
such loss or expense shall be presumed to be correct absent
manifest error.

     2.12 USE OF PROCEEDS.  The proceeds of the Loans shall be used 
exclusively to finance the costs of the Company's gas inventory including
supporting commercial paper associated with gas inventory financing.

     2.13 CAPITAL ADEQUACY.  If either (i) the introduction of, or 
any change or phasing in of any law or regulation or in the 
interpretation thereof by any Governmental Body charged with the 
administration thereof or (ii) compliance with any directive, 
guideline or request from any central bank or Governmental Body 
(whether or not having the force of law) promulgated or made after 
the date hereof (but including, in any event, any law, rule, regulation,
interpretation, directive, guideline or request contemplated by
the report dated July 1988 entitled "International Convergence of
Capital Measurement and Capital Standards" issued by the Basle
Committee on Banking Regulations and Supervisory Practices)
affects or would affect the amount of capital required or
expected to be maintained by a Bank (or any lending office of
such Bank) or any corporation directly or indirectly owning or
controlling such Bank (or any lending office of such Bank) and
such Bank shall have determined that such introduction, change or
compliance has or would have the effect of reducing the rate of
return on such Bank's capital or the asset value to such Bank of
any Loan made by such Bank as a consequence, directly or
indirectly, of its obligations to make and maintain the funding
of Loans hereunder to a level below that which such Bank could
have achieved but for such introduction, change or compliance
(after taking into account such Bank's policies regarding capital
adequacy) by an amount deemed by such Bank to be material, then,
upon demand by such Bank, the Company shall promptly pay to such
Bank such additional amount or amounts as shall be sufficient to
compensate such Bank for such reduction on the rate of return.
Each Bank shall calculate such amount or amounts payable to it
under this paragraph 2.13 in a manner consistent with the manner
in which it shall calculate similar amounts payable to it by
other borrowers having provisions in their credit agreements
comparable to this paragraph 2.13. Each Bank agrees to provide
the Company with a certificate setting forth a description of any
such amount in respect of which it seeks payment under this
paragraph 2.13. Each Bank's determination of such amount or
amounts that will compensate such Bank for such reductions shall
be presumed correct absent manifest error.

        2.14 EXTENSION OF REVOLVING CREDIT TERMINATION DATE. The Company may,
pursuant to a Commitment Extension Request delivered to the Agent and each Bank
not less than 60 days prior to the then scheduled Revolving Credit Termination
Date, request each Bank to extend its Commitment for an additional
three-hundred sixty-four (364) day period expiring on the 364th day of such
period (or, if such date is not a Business Day, on the immediately preceding
Business Day). Each of the Banks shall, within 30 days of receipt of a
Commitment Extension Request from the Company, provide the Company with a
non-binding preliminary indication regarding whether such Bank is likely to
consent to the extension of its Commitment. If all Banks consent to the
extension of their respective Commitments, which consents shall be given no
less than 30 days prior to the then scheduled Revolving Credit Termination
Date, the Revolving Credit Termination Date shall be so extended. In the event
that less than all of the Banks consent to an extension of their respective
Commitments, the Revolving Credit Termination Date shall not be extended,
unless the Company designates another bank reasonably satisfactory to the Banks
willing so to extend the Revolving Credit Termination Date, or one or more of
the signatory Banks elect to increase its or their Commitments to the amount of
the Commitment of the nonconsenting Bank (any such other bank, including any
signatory Bank, to the extent of, and with respect to such an increase in its
Commitment, being herein called a "Replacement Bank"), to assume the Commitment
and obligations of such nonconsenting Bank or Banks (each, a "Nonconsenting
Bank") with respect to its Loans, and to purchase the outstanding Note of such
nonconsenting Bank and such Nonconsenting Bank's rights with respect to its
Loans, without recourse or warranty, for a purchase price equal to the
outstanding principal balance of the Note of such Nonconsenting Bank, plus all
interest accrued thereon and all other amounts owing to such Nonconsenting Bank
hereunder. Upon such assumption and purchase by a Replacement Bank, and
provided that the Banks (excluding the Nonconsenting Banks and each Replacement
Bank) have consented to the Commitment Extension Request prior to the then
scheduled Revolving Credit Termination Date, (i) the Revolving Credit
Termination Date shall be so extended, (ii) each such Replacement Bank shall be
deemed to be a "Bank" for purposes of this Agreement, and (iii) each
Nonconsenting Bank shall cease to be a "Bank" for all purposes of this
Agreement (except with respect to its rights hereunder to be reimbursed for
costs and expenses, and to indemnification with respect to, matters
attributable to events, acts or conditions occurring prior to such assumption
and purchase) and shall no longer have any obligations hereunder.

        Each Bank will use its best efforts to respond promptly to any
Commitment Extension Request, provided that no Bank's failure to so respond
shall create any claim against it or have the effect of extending the Revolving
Credit Termination Date.

        2.15 EXTENSION TO TERMINATION DATE.  Subject to the terms and
conditions hereof, the Company may, upon notice delivered to the Agent and each
Bank not less than 10 days prior to the then scheduled Revolving Credit
Termination Date, elect to extend the scheduled maturity of the Loans
outstanding on the Revolving Credit Termination Date from such date to the
Termination Date so long as no Event of Default has occurred and is continuing
on the Revolving Credit Termination Date.  On the Revolving Credit Termination
Date, the Company shall execute and deliver to each Bank a new promissory note
in substantially the form of Exhibit E, with appropriate insertions (as
endorsed and as amended or otherwise modified from time to





<PAGE>   23

                            -18-


time, a "Term Note" and, collectively, the "Term Notes"), payable
to the order of each Bank and representing the obligation of the
Company to pay the aggregate unpaid principal amount of all Loans
made by such Bank, with interest thereon as prescribed or
determined herein.  Each Bank is authorized to record each
payment or prepayment of principal of the Loans on the applicable
grid (and any continuations thereof) connected to and
constituting a part of its Term Note.  No failure to so record or
any error in so recording shall affect the obligation of the
Company to repay the Loans, with interest thereon, as herein
provided.  Each Term Note shall (a) be dated the date of the
Revolving Credit Termination Date, (b) be stated to mature on the
Termination Date, and (c) bear interest for the period from and
including the date thereof on the unpaid principal amount thereof
from time to time outstanding at the applicable interest rate per
annum determined as provided herein.  Upon receipt by each Bank
from the Company of its Term Note in accordance with the terms of
this #2.15, each Bank will promptly return to the Company the
Revolving Credit Note held by such Bank.

     2.16 NOTICE OF COSTS; SUBSTITUTION OF BANKS.  Each Bank will 
notify the Company of any event that will entitle such Bank to 
compensation under paragraphs 2.10 and 2.13 as promptly as practicable, 
but in any event within 45 days after an officer of the Bank 
responsible for matters concerning this Agreement has knowledge of 
such event. If such Bank fails to give such notice, such Bank shall 
only be entitled to such compensation for the period commencing on the 
date of the giving of such notice. Each Bank shall use its best efforts 
to avoid the need to give a notice under paragraph 2.10 or 2.13 by 
designating a different Applicable Lending Office outside of the United
States if such designation would avoid the need to give such
notice and will not, in the sole opinion of such Bank, be
disadvantageous to such Bank. In the event the Company receives
such notice or is otherwise required under the provisions of
paragraphs 2.10 or 2.13 to make payments in a material amount to
any Bank, the Company may, so long as no Event of Default shall
have occurred and be continuing, elect to substitute such Bank as
a party to this Agreement; provided that, concurrently with such
substitution, (i) the Company shall pay that Bank all principal,
interest and fees and other amounts (including without
limitation, amounts, if any, owed under paragraph 2.10, 2.11 or
2.13) owed to such Bank through such date of termination, (ii)
another commercial bank satisfactory to the Company and the Agent
(or if the Agent is also the Bank to be substituted, the
successor Agent) shall agree, as of such date, to become a Bank
(whether by assignment or amendment) for all purposes under this
Agreement and to assume all obligations of the Bank to be
substituted as of such date, and (iii) all documents, supporting
materials and fees necessary, in the judgment of the Agent (or if
the Agent is also the Bank to be substituted, the successor
Agent) to evidence the substitution of such Bank shall have been
received and approved by the Agent as of such date.


3.   FEES; PAYMENTS.

     3.1  FACILITY FEE.  The Company agrees to pay to the Agent
for the account of the Banks a fee (the "Facility Fee") equal to
the rate per annum determined by reference to Exhibit B hereto
based upon the Debt Rating of the Company multiplied by the
Aggregate Commitment, which Facility Fee shall be payable in
arrears on the last day of each March, June, September and






<PAGE>   24

                           -19-


December of each year, commencing on the first such date
following the Effective Date and continuing until the later of
the Termination Date or the date all sums due hereunder and under
the Notes are paid in full; provided that if the Company has no
Debt Rating, the Facility Fee shall be determined at the highest
rate per annum for the relevant period set forth on Exhibit B.

     3.2  FEES OF THE AGENT.  The Company agrees to pay to the Agent 
for its own account, such fees (the "Agent's Fees") for its services 
hereunder in such amounts and at such times as previously agreed upon 
by the Company and the Agent.

     3.3  COMPUTATION OF INTEREST AND FEES.

     (a)  Interest in respect of Alternate Base Rate Loans, the
Facility Fee and all other fees payable by the Company hereunder
shall be calculated on the basis of a 365/366-day year for the
actual number of days elapsed. Interest in respect of Eurodollar
Rate Loans shall be calculated on the basis of a 360-day year for
the actual number of days elapsed. Any change in the interest
rate on a Loan resulting from a change in the Alternate Base Rate
or Eurodollar Rate shall become effective as of the opening of
business on the day on which such change shall become effective.
The Agent shall, as soon as practicable, notify the Company and
the Banks of the effective date and the amount of each such
change but failure of the Agent to do so shall not in any manner
affect the obligation of the Company to pay interest on the Loans
in the amounts and on the dates required.

     (b)  Each determination of the Alternate Base Rate or the
Eurodollar Rate by the Agent pursuant to any provision of this
Agreement shall be presumed to be correct absent manifest error.

     3.4  PRO RATA TREATMENT AND APPLICATION OF PRINCIPAL
PAYMENTS.  Each Borrowing by the Company from the Banks, any
conversion of Loans from one Type to the same or another Type,
and any reduction of the Aggregate Commitments of the Banks,
shall be made pro rata according to the Commitment Percentage of
each Bank. All payments (including prepayments) to be made by the
Company on account of principal and interest on Loans comprising
the same Borrowing shall be made pro rata according to the
outstanding principal amount of each Bank's Loans.  All payments
by the Company on all Loans shall be made without set-off or
counterclaim and shall be made prior to 12:00 noon, Boston time,
on the date such payment is due, to the Agent for the account of
the Banks at the Agent's office specified in paragraph 11.1, in
each case in lawful money of the United States of America and in
immediately available funds, and, as between the Company and the
Banks, any payment by the Company to the Agent for the account of
the Banks shall be deemed to be payment by the Company to the
Banks; provided, however, that any payment received by the Agent
on any Business Day after 12:00 noon shall be deemed to have been
received on the immediately succeeding Business Day. The Agent
shall distribute such payments to the Banks promptly upon receipt
in like funds as received. If any payment hereunder or on any
Note becomes due and payable on a day other than a Business Day,
the maturity thereof shall be extended to the next succeeding
Business Day (unless, in the case of Eurodollar Loans, the result
of such extension would be to extend such






<PAGE>   25

                             -20-


payment into another calendar month, in which event such payment shall
be made on the immediately preceding Business Day) and, with respect to
payments of principal, interest thereon shall be payable at the then applicable
rate during such extension.

4    REPRESENTATIONS AND WARRANTIES. In order to induce the  Agent and
the Banks to enter into this Agreement, the Company hereby  represents and
warrants to the Agent and to each Bank that:

        4.1  SUBSIDIARY.  The Company has the Subsidiaries set forth in 
Exhibit G. The shares of each corporate Subsidiary owned by the Company  are
duly authorized, validly issued, fully paid and non-assessable and are owned
free and clear of any Liens, except Liens permitted by paragraph 8.2.

        4.2  CORPORATE EXISTENCE AND POWER.  Each of the Company and each 
Subsidiary is a corporation duly organized, validly existing and in  good
standing under the laws of the Commonwealth of Massachusetts and  has all
requisite corporate power and authority to own its Property and  to carry on
its business as now conducted. Each of the Company and each Subsidiary is in
good standing and duly qualified to do business in each  jurisdiction in which
the failure to so qualify would have a material  adverse effect on the
financial condition, Property, prospects or  operations of the Company and its
Subsidiaries on a Consolidated basis.

        4.3  CORPORATE AUTHORITY.  The Company has full corporate power  and
authority to enter into, execute, deliver and carry out the  terms of this
Agreement and to make the borrowings contemplated hereby,  to execute, deliver
and carry out the terms of the Notes and to incur the obligations provided for
herein and therein, all of which have been duly authorized by all necessary
corporate action on its part and are in full compliance with its Charter and
By-Laws. No consent or approval of, or exemption by, shareholders or any
Governmental Body is required to authorize, or is required in connection with
the execution, delivery and performance of, this Agreement and the Notes, or is
required as a condition to the validity or enforceability of this Agreement and
the Notes, except for the approval of the DPU referred to in paragraph 5.6
which has been duly obtained and which remains in full force and effect and is
final and is not subject to appeal.

        4.4  BINDING AGREEMENT. This Agreement constitutes and the Notes, when
issued and delivered pursuant hereto for value received, will constitute, the
valid and legally binding obligations of the Company enforceable against the
Company in accordance with their respective terms, except as such
enforceability may be limited by equitable principles and by applicable
bankruptcy, insolvency, reorganization, moratorium or similar laws affecting
the rights of creditors generally.

        4.5  LITIGATION. Except for the matters set forth in the Designated
Documents, there are no actions, suits or arbitration proceedings (whether or
not purportedly on behalf of the






<PAGE>   26

                             -21-


Company or any Subsidiary) pending or to the knowledge of the management of the
Company threatened against the Company or any Subsidiary, or maintained by the  
Company or any Subsidiary, in law or in equity before any Governmental Body
which, if decided adversely to the Company or such Subsidiary, would result in
a material adverse change in the financial condition, Property or operations 
of the Company and its Subsidiaries on a Consolidated basis, after giving
effect to reserves reflected in the Financial Statements or the footnotes
thereto. There are no proceedings pending or threatened against the Company or
any Subsidiary which call into question the validity and enforceability of this
Agreement or the Notes.

        4.6  NO CONFLICTING AGREEMENTS. Except for the matters set forth in
Designated Documents, neither the Company nor any Subsidiary is in default
under any agreement to which it is a party or by which it or any of its
Property is bound the effect of which would have a material adverse effect on
the financial condition, Property, prospects or operations of the Company and
its Subsidiaries on a Consolidated basis. No provision of the Charter or
By-Laws of the Company, and no provision of any existing mortgage, indenture
(including the Indenture), contract, agreement, statute (including, without
limitation, any applicable usury or similar law), rule, regulation, judgment,
decree or order binding on the Company or any Subsidiary would in any way
prevent the execution, delivery or carrying out of the terms of this Agreement
and the Notes, and the taking of any such action will not constitute a default
under, or result in the creation or imposition of, or obligation to create, any
Lien not permitted by paragraph 8.2 upon the Property of the Company or any
Subsidiary pursuant to the terms of any such mortgage, indenture, contract or
agreement.

        4.7  TAXES. Each of the Company and its Subsidiaries has filed or
caused to be filed all tax returns material to the Company and its Subsidiaries
required by law to be filed, and has paid, or has made adequate provision for
the payment of, all taxes shown to be due and payable on said returns or in any
assessments made against it. No tax liens have been filed and no claims are
being asserted with respect to such taxes which are required by GAAP to be
reflected in the Financial Statements and are not so reflected therein. The
Internal Revenue Service has audited and settled upon, or the applicable
statutes of limitation have run upon, all Federal income tax returns of the
Company and its Subsidiaries through the tax year ended December 31, 1987, and,
to the extent required by GAAP, the results of all such audits are reflected in
the Financial Statements. The charges, accruals and reserves on the books of
the Company and its Subsidiaries with respect to all taxes are considered by
the management of the Company to be adequate, and the Company knows of no
unpaid assessment which is due and payable against the Company or any of the
Subsidiaries which would have a material adverse effect on the financial
condition, Property, prospects or operations of the Company and its
Subsidiaries on a Consolidated basis, except such thereof as are being
contested in good faith and by appropriate proceedings diligently conducted and
for which adequate reserves have been set aside in accordance with GAAP.

        4.8  FINANCIAL STATEMENTS. The Company heretofore delivered to each
Bank (i) copies of the Consolidated Balance Sheets at December 31, 1991 and
1992, and the related





<PAGE>   27

                           -22-


Consolidated Statements of Income, Retained Earnings and Changes in Financial
Position for the years then ended and (ii) copies of the Consolidated quarterly
reports of the Company and its Subsidiaries as of March 31, 1993, June 30, 1993
and September 30, 1993, each containing a Consolidated balance sheet and
Consolidated statements of income and cash flows of the Company and its

(i) above were audited and reported on by the Accountants on February 25, 1993,
and the financial statements set forth in (ii) above were prepared by the
Company. The Financial Statements fairly present the Consolidated financial
condition and the Consolidated results of operations of the Company and its
Subsidiaries as of the dates and for the periods indicated therein, and have
been prepared in conformity with GAAP. Except (a) as reflected in the financial
statements specified in (i) above or in the footnotes thereto, or (b) as
otherwise disclosed to the Banks in a writing specifically referring to this
paragraph 4.8, neither the Company nor any Subsidiary has any obligation or
liability of any kind (whether fixed, accrued, contingent, unmatured or
otherwise) which is material to the Company and its Subsidiaries on a
Consolidated basis and which, in accordance with GAAP, should have been shown
on such financial statements and were not, other than those incurred in the
ordinary course of their respective businesses since December 31, 1992. Since
December 31, 1992, each of the Company and each Subsidiary has conducted its
business only in the ordinary course, and as of the Effective Date there
has been no adverse change in the financial condition, Property, operations or
prospects of the Company and its Subsidiaries which is material to the Company
and its Subsidiaries on a Consolidated basis.

        4.9  COMPLIANCE WITH APPLICABLE LAWS. Except as set forth in the
Designated Documents, neither the Company nor any Subsidiary is in default with
respect to any judgment, order, writ, injunction, decree or decision of any
Governmental Body applicable to the Company or such Subsidiary which default
would have a material adverse effect on the financial condition, Property,
prospects or operations of the Company and its Subsidiaries on a Consolidated
basis. Except as set forth in the Designated Documents, each of the Company and
each Subsidiary is complying in all material respects with all applicable
material statutes and regulations of all Governmental Bodies, including ERISA
and all Environmental Laws, a violation of which would have a material adverse
effect on the financial condition, Property, prospects or operations of the
Company and each Subsidiary on a Consolidated basis.

        4.10 GOVERNMENTAL REGULATIONS. The Company is not an "Investment
Company" as such term is defined in the Investment Company Act of 1940, as
amended.

        4.11 PROPERTY.  Each of the Company and each Subsidiary has good  and
marketable title to all of its Property, title to which is material to the
Company and its Subsidiaries on a Consolidated basis, subject to no Lien, 
except as permitted by paragraph 8.2.

        4.12 FEDERAL RESERVE REGULATIONS.  The Company is not engaged 
principally, or as one of its important activities, in the business of 
extending credit for the purpose of purchasing or carrying any margin  stock
within the meaning of Regulation U of the Board of Governors of the





<PAGE>   28

                           -23-


Federal Reserve System, as amended. No part of the proceeds of the Loans will
be used (i) to purchase or carry any such margin stock, (ii) to extend credit
to others for the purpose of purchasing or carrying any margin stock, (iii) for
a purpose which violates the provisions of Regulations G, U and X of the Board
of Governors of the Federal Reserve System, as amended, or (iv) for a purpose
which violates any other applicable law, rule   or regulation of any
Governmental Body. Not more than 25% of the value of the aggregate of the
assets of the Company subject to the provisions of this Agreement is
represented by margin stock within the meaning of said Regulation U.

        4.13 NO MISREPRESENTATION. No representation or warranty contained
herein and no certificate or report furnished or to be furnished by the Company
in connection with the transactions contemplated hereby, contains or will
contain a misstatement of material fact, or omits or will omit to state a
material fact required to be stated in order to make the statements herein or
therein contained not misleading in the light of the circumstances under which
made.

        4.14 PENSION PLANS. Each Plan, and to the best of the Company's
knowledge each Multiemployer Plan, established or maintained by the Company and
its Subsidiaries, is in material compliance with the applicable provisions of
ERISA and the Code, and the Company and its Subsidiaries have filed all
material reports required to be filed with respect to each such Plan by ERISA
and the Code. The Company and its Subsidiaries have met all requirements with
respect to funding the Plans imposed by ERISA or the Code. Since the effective
date of ERISA, there have not been, nor are there now existing, any events or
conditions which would permit any Plan and to the best of the Company's
knowledge any Multiemployer Plan to be terminated under circumstances which
would cause the lien provided under Section 4068 of ERISA to attach to the
Property of the Company or any of its Subsidiaries. Since the effective date of
ERISA, no reportable event as defined in Title IV of ERISA, which constitutes
grounds for the termination of any Plan and to the best of the Company's
knowledge any Multiemployer Plan, has occurred and no Plan or any related trust
has been terminated in whole or in part which would have a material adverse
effect on the financial condition, Property or operations of the Company and
its Subsidiaries on a Consolidated basis.

        4.15 PUBLIC UTILITY HOLDING COMPANY ACT. The Company and its
Subsidiaries are "subsidiaries" of a "holding company" which is exempt under
the Public Utility Holding Company Act of 1935, pursuant to orders of the
Securities Exchange Commission, which orders remain in full force and effect.

        4.16 APPROVALS. The Company has obtained all authorizations, approvals
or consents of and made all filings or registrations with all Governmental
Bodies as are necessary to be obtained or made by the Company for the
execution, delivery or performance by the Company of this Agreement or the
Notes and all such authorizations, approvals and consents are in full force and
effect.

have been terminated and that the Notes, all accrued interest
thereon and all other amounts owing under this Agreement are

an event specified in paragraphs 9(h) or 9(i), the Commitments
shall automatically terminate and the Notes (with accrued
interest thereon) and all other amounts owing under this
Agreement shall become immediately due and payable without notice
to the Company. Except for any notice expressly provided for in
this paragraph 9, the Company hereby expressly waives any
presentment, demand, protest, notice of protest or other notice
of any kind. The Company hereby further expressly waives and
covenants not to assert any appeasement, valuation, stay,
extension, redemption or similar laws, now or at any time
hereafter in force which might delay, prevent or otherwise impede
the performance or enforcement of this Agreement or the Notes.

     In the event that the unpaid principal balance of the Notes,
all accrued interest thereon and all other amounts owing under
this Agreement shall have been declared due and payable pursuant
to the provisions of this paragraph 9, the Agent may, and, upon
(i) the request of the Majority Banks and (ii) the providing by
all of the Banks to the Agent of an indemnity in form and
substance satisfactory to the Agent in accordance with paragraph
10.3 against all expenses and liabilities shall, proceed to
enforce the rights of the holders of the Notes by suit in equity,
action at law and/or other appropriate proceedings, whether for
payment or the specific performance of any covenant or agreement
contained in this Agreement or the Notes. The Agent shall be
justified in failing or refusing to take any action hereunder and
under the Notes unless it shall be indemnified to its
satisfaction by the Banks pro rata according to the aggregate
outstanding principal balance of the Notes against any and all
liabilities and expenses which may be incurred by it by reason of
taking or continuing to take any such action. In the event that
the Agent, having been so indemnified, or not being indemnified
to its satisfaction, shall fail or refuse so to proceed, any Bank
shall be entitled to take such action as it shall deem
appropriate to enforce its rights hereunder and under its Notes,
with the consent of the Banks, it being understood and intended
that no one or more of the holders of the Notes shall have any
right to enforce payment thereof except as provided in this
paragraph 9 and in paragraph 12.

     If an Event of Default shall have occurred and shall be
continuing, the Agent may, and at the request of the Majority
Banks shall, notify the Company (by telephone or otherwise) that
all or such lesser amount as the Majority Banks shall designate
of the outstanding Eurodollar Rate





<PAGE>   37

                           -32-


Loans automatically shall be converted to Alternate Base Rate Loans, in which
event such Eurodollar Rate Loans automatically shall be converted to Alternate  
Base Rate Loans on the date such notice is given. If such notice is given,
notwithstanding anything in paragraph 2.6 to the contrary, no Alternate Base
Rate Loan may be converted to a Eurodollar Rate Loan if an Event of Default has
occurred and is continuing at the time the Company shall notify the Agent of
its election to so convert.


10.  THE AGENT. The Banks and the Agent agree by and among themselves that:

        10.1 APPOINTMENT.   FNBB is hereby irrevocably designated the Agent by
each of the other Banks to perform such duties on behalf of the other Banks and
itself, and to have such powers, as are set forth herein and as are reasonably
incidental thereto.

        10.2 DELEGATION OF DUTIES; ETC.  The Agent may execute any duties  and
perform any powers hereunder by or through agents or employees,  and shall be
entitled to consult with legal counsel and any accountant  or other
professional selected by it. Any action taken or omitted to be taken or
suffered in good faith by the Agent in accordance with the  opinion of such
counsel or accountant or other professional shall be  full justification and
protection to the Agent.

        10.3 INDEMNIFICATION.  The Banks agree to indemnify the Agent in  its
capacity as such, to the extent not reimbursed by the Company,  pro rata
according to their respective Commitments as of the Effective  Date, from and
against any and all claims, liabilities, obligations,  losses, damages,
penalties, actions, judgments, suits, costs,  expenses or disbursements of any
kind or nature whatsoever which may  be imposed on, incurred by, or asserted
against the Agent in any way relating to or arising out of this Agreement or
the Notes or any action taken or omitted to be taken or suffered in good faith
by the Agent hereunder or thereunder, provided that no Bank shall be liable for
any portion of any of the foregoing items resulting from the gross negligence
or willful misconduct of the Agent. Without limitation of the foregoing, each
Bank agrees to reimburse the Agent promptly for its pro-rata share of any
reasonable out-of-pocket expenses (including counsel fees) incurred by the
Agent in connection with the preparation, execution, administration or
enforcement of, or legal advice in respect of rights or responsibilities under,
this Agreement and the Notes, to the extent that the Agent, having sought
reimbursement for such expenses from the Company, is not promptly reimbursed by
the Company. Any reference herein and in any document executed in connection
herewith, to the Banks providing an indemnity in form and substance
satisfactory to the Agent prior to the Agent taking any action hereunder shall
be satisfied by the Banks executing an agreement confirming their agreement to
promptly indemnify the Agent in accordance with this paragraph 10.3.

        10.4 EXCULPATORY PROVISIONS.  Neither Agent, nor any of its officers,
directors, employees or agents, shall be liable for any action taken or omitted
to be taken or suffered by it or them hereunder or under the Notes, or in
connection herewith or therewith, except that the






<PAGE>   38

                              -33-


Agent shall be liable for its own gross negligence or willful misconduct. The
Agent shall not be liable in any manner for the effectiveness, enforceability,
collectibility, genuineness, validity or the due execution of this Agreement or
the Notes, or for the due authorization, authenticity or accuracy of the
representations and warranties contained herein or in any other certificate,
report, notice, consent, opinion, statement, or other document furnished or to
be furnished hereunder, and the Agent shall be entitled to rely upon any of the
foregoing believed by it to be genuine and correct and to have been signed and
sent or made by the proper Person. The Agent shall not be under any duty or
responsibility to any Bank to ascertain or to inquire into the performance or
observance by the Company or any Subsidiary of any of the provisions hereof or
of the Notes or of any document executed and delivered in connection herewith
or therewith. Each other Bank expressly acknowledges that the Agent has not
made any representations or warranties to it and that no act taken by the Agent
shall be deemed to constitute any representation or warranty by the Agent to
any other Bank. Each Bank acknowledges that it has taken and will continue to
take such action and has made and will continue to make such investigation as
it deems necessary to inform itself of the affairs of the Company and each
Subsidiary, and each Bank acknowledges that it has made and will continue to
make its own independent investigation of the creditworthiness and the business
and operations of the Company and its Subsidiaries, and that, in entering into
this Agreement, and in agreeing to make its Loans, it has not relied and will
not rely upon any information or representations furnished or given by the
Agent or any other Bank.

        10.5 AGENT IN ITS INDIVIDUAL CAPACITY. With respect to its Loans and
any renewals, extensions or deferrals of the payment thereof and any Note
issued to or held by it, the Agent shall have the same rights and powers
hereunder as any Bank, and may exercise the same as though it were not the
Agent, and the term "Bank" or "Banks" shall, unless the context otherwise
requires, include the Agent in its individual capacity. FNBB and its affiliates
may accept deposits from, lend money to, act as trustee or other fiduciary in
connection with transactions involving, and otherwise engage in any business
with the Company and its affiliates and any Person who may do business with or
own securities of the Company or any affiliate of the Company, all as if FNBB
were not the Agent hereunder and without any obligation to account or report
therefor to any Bank.

        10.6 KNOWLEDGE OF DEFAULT. It is expressly understood and agreed that
the Agent shall be entitled to assume that no Event of Default has occurred and
is continuing, unless the officers of the Agent who are responsible for matters
concerning this Agreement shall have actual knowledge of such occurrence or
shall have been notified in writing by a Bank that such Bank considers that an
Event of Default has occurred and is continuing and specifying the nature
thereof.

        In the event the Agent shall have acquired actual knowledge of any
Event of Default, it shall promptly give notice thereof to the Banks.

        10.7 RESIGNATION OF AGENT. If at any time the Agent deems it advisable,
in its sole discretion, it may submit to each of the Banks a written
notification of its resignation as Agent






<PAGE>   39

                               -34-

after the date of such notice. If the Agent resigns hereunder, the Company
shall have the right to appoint, with the prior written approval of the Banks,
which approval shall not be unreasonably withheld, a successor Agent hereunder,
provided, however that upon the occurrence and during the continuance of an
Event of Default, the Banks shall have the right to appoint such successor
Agent hereunder. The successor Agent shall be a commercial bank organized under
the laws of the United States of America or of any State thereof and having a
combined capital and surplus of at least $100,000,000. Upon the acceptance of
any appointment as Agent hereunder by a successor Agent, such successor Agent
shall thereupon succeed to and become vested with all the rights, powers,
privileges and duties of the Agent hereunder, and the retiring Agent shall
be discharged from any further duties and obligations under this Agreement. The
Company and the Banks agree to execute such documents as shall be necessary to
effect such appointment. After the retiring Agent's resignation or removal
hereunder, the provisions of this paragraph 10 shall inure to its benefit as to
any actions taken or omitted to be taken by it while the Agent under this
Agreement. If at any time hereunder there shall not be a duly appointed and
acting Agent, the Company agrees to make each payment due hereunder and under
the Notes directly to the Banks entitled thereto.

        10.8 REQUESTS TO THE AGENT. Whenever the Agent is authorized and
empowered hereunder on behalf of the Banks to give any approval or consent, or
to make any request, or to take any other action on behalf of the Banks, the
Agent shall be required to give such approval or consent, or to make such
request or to take such other action only when so requested in writing by the
Majority Banks subject, however, to the provisions of paragraph 13.

invalidate any such action, consent or notice in respect of the Company.

12.  RIGHT OF SET-OFF.  Regardless of the adequacy of any       collateral,
upon the occurrence and during the continuance of any Event of Default, each
Bank is hereby expressly and irrevocably authorized by the Company at any time
and from time to time, without notice to the Company, to set-off, appropriate,
and apply all moneys, securities and other Property and the proceeds thereof
now or hereafter held or received by or in transit to such Bank from or for the
account of the Company, whether for safekeeping, pledge, transmission,
collection or otherwise, and also upon any and all deposits (general and
special), account balances and credits of the Company with such Bank at any
time existing against any and all obligations of the Company to the Banks and
to each of them arising under this Agreement and the Notes, and the Company
shall continue to be liable to each Bank for any deficiency with interest at
the rate or rates set forth in subparagraph 2.7(b). Each of the Banks agrees
with each other Bank that (a) if an amount to be set off is to be applied to
any obligations of the Company to such Bank, other than obligations evidenced
by the Notes held by such Bank, such amount shall be applied ratably to such
other obligations and to the obligations evidenced by all such Notes held by
such Bank and (b) if such Bank shall receive from the Company, whether by

enforcement of the claim evidenced by the Notes held by such Bank by
proceedings against the Company at law or in equity or by proof thereof in
bankruptcy, reorganization, liquidation, receivership or similar proceedings,

Banks with respect to such excess, either by way of distribution, PRO TANTO
assignment of claims, subrogation or otherwise as shall result in each Bank
receiving in respect of the Notes held by each Bank, its proportionate payment
as contemplated by this Agreement; PROVIDED that if all or any part of such
excess payment is thereafter recovered from such Bank, such disposition and
arrangements shall be rescinded and the amount restored to the extent of such
recovery, but without interest.

13.  AMENDMENTS, WAIVERS AND CONSENTS.  Except as otherwise expressly set forth
herein, with the written consent of the Majority Banks, the Agent shall,
subject to the provisions of this paragraph 13, from time to time enter into
agreements amendatory or supplemental hereto with the Company for the purpose
of changing any provisions of this Agreement or the Notes, or changing in any
manner the rights of the Banks, the Agent or the Company hereunder and
thereunder, or waiving compliance with any provision of this Agreement or
consenting to the non-compliance thereof.  Notwithstanding the foregoing, the
consent of all of the Banks shall be required with respect to any amendment,
waiver or consent (i) changing the Aggregate Commitments or the Commitment of
any Bank or (ii) changing the maturity of any Loan, or the rate of interest of,
time or manner of payment of interest on or principal of, or the principal
amount of any Loan, or the amount, time or manner of payment of any fees
hereunder, or modifying this paragraph 13. Any such amendatory or supplemental
agreement, waiver or consent shall apply equally to each of the Banks and shall
be binding on the Company and all of the Banks and the Agent. Any waiver or
consent shall be for such period and subject to such conditions or limitations
as shall be specified therein, but no waiver or consent shall extend to any
subsequent or other Event of Default, or impair any right or remedy consequent
thereupon. In the case  of any waiver or consent, the rights of the Company,
the Banks and the Agent under this Agreement and the Notes shall be otherwise
unaffected. Nothing contained herein shall be deemed to require the Agent to
obtain the consent of any Bank with respect to any change in the amount or
terms of payment of the Agent's Fees. The Company shall be entitled to rely
upon the provisions of any such amendatory or supplemental agreement, waiver or
consent if it shall have obtained any of the same in writing from the Agent who
therein shall have represented that such agreement, waiver or consent has been
authorized in accordance with the provisions of this paragraph 13.


14.  OTHER PROVISIONS.

        14.1 NO WAIVER OF RIGHTS BY THE BANKS. No failure on the part of the
Agent or of any Bank to exercise, and no delay in exercising, any right or
remedy hereunder or under the Notes shall operate as a waiver thereof, except
as provided in paragraph 13, nor shall any single or partial exercise by the
Agent or any Bank of any right, remedy or power hereunder or under the Notes
preclude any other or future exercise thereof, or the exercise of any other
right, remedy or power. The rights, remedies and powers provided herein and in
the Notes are cumulative and not exclusive of any other rights, remedies or
powers which the Agent or the Banks or any holder of a Note would otherwise
have. Notice to or demand on the Company in any circumstance in which the terms
of this Agreement or the Notes do not require notice or demand to be given
shall not entitle the Company to any other or further notice or demand in
similar or other circumstances or constitute a waiver of the rights of the
Agent or any Bank or the holder of any Note to take any other or further action
in any circumstances without notice or demand.

        14.2 HEADINGS; PLURALS. Paragraph and subparagraph headings have been
inserted herein for convenience only and shall not be construed to be a part of
this Agreement. Unless the





<PAGE>   43

                             -38-


context otherwise requires, words in the singular number include the plural,
and words in the plural include the singular.

        14.3 COUNTERPARTS. This Agreement may be executed in any number of
counterparts, each of which shall be an original and all of which shall
constitute one agreement. It shall not be necessary in making proof of this
Agreement or of any document required to be executed and delivered in
connection herewith or therewith to produce or account for more than one
counterpart.

        14.4 SEVERABILITY. Every provision of this Agreement and the Notes is
intended to be severable, and if any term or provision hereof or thereof shall
be invalid, illegal or unenforceable for any reason, the validity, legality and
enforceability of the remaining provisions hereof or thereof shall not be
affected or impaired thereby, and any invalidity, illegality or
unenforceability in any jurisdiction shall not affect the validity, legality or
enforceability of any such term or provision in any other jurisdiction.

        14.5 INTEGRATION. All exhibits to this Agreement shall be deemed to be
a part of this Agreement. This Agreement, the exhibits hereto and the Notes
embody the entire agreement and understanding between the Company, the Agent
and the Banks with respect to the subject matter hereof and thereof and
supersede all prior agreements and understandings between the Company, the
Agent and the Banks with respect to the subject matter hereof and thereof.

        14.6 SALES AND PARTICIPATIONS IN LOANS AND NOTES; SUCCESSORS AND
ASSIGNS; SURVIVAL OF REPRESENTATIONS AND WARRANTIES.

        (a)  Each Bank shall have the right with the prior written consent of
the Company (which consent may be withheld for any reason or no reason), upon
written notice to the Agent and the Company to sell, assign, transfer or
negotiate all or any part of the Loans and the Notes and its Commitment to one
or more Banks. In addition, each Bank shall have the right with the prior
written consent of the Company (which consent may be withheld for any reason or
for no reason) upon written notice to the Agent and the Company to sell,
assign, transfer or negotiate all or any part (but not less than $5,000,000) of
the Loans and the Notes and its Commitment to one or more commercial banks or
other financial institutions. In the case of any sale, assignment, transfer or
negotiation of all or any such part of the Loans and the Notes authorized under
this paragraph 14.6 (a), the assignee or transferee shall have, to the extent
of such sale, assignment, transfer or negotiation, the same rights, benefits
and obligations as it would if it were a Bank hereunder and a holder of such
Note, including, without limitation, (x) the right to approve or disapprove of
actions which in accordance with the terms hereof, require the approval of the
Majority Banks and (y) the obligation to fund Loans directly to the Agent
pursuant to paragraph 2.2.

        (b)  Notwithstanding paragraph 14.6 (a), each Bank may grant
participations in all or any part (but not less than $5,000,000) of its Loans
and its Notes to one or more commercial





<PAGE>   44

                           -39-


banks, insurance companies or other financial institutions,
pension funds or mutual funds; provided that (i) any such
disposition shall not, without the prior written consent of the
Company, require the Company to file a registration statement
with the Securities and Exchange Commission or apply to qualify
the Loans and the Notes under the blue sky laws of any state and
(ii) the holder of any such participation, other than an
Affiliate of such Bank, shall not have any rights or obligations
hereunder and shall not be entitled to require such Bank to take
or omit to take any action hereunder except action directly
affecting the extension of the maturity of any portion of the
principal amount of, or interest on, the Loan allocated to such
participation, or a reduction of the principal amount of, or the
rate of interest payable on, such Loans.

     Notwithstanding the foregoing provisions of this paragraph
14.6, each Bank may at any time with the prior written consent of
the Company (which consent shall not be unreasonably withheld)
sell, assign, transfer, or negotiate all or any part of the
Loans to any Affiliate of such Bank; provided that an Affiliate
to whom such disposition has been made shall not be considered a
"Bank", and the assigning Bank shall be considered not to have
disposed of any Loans so assigned, for purposes of determining
the Majority Banks under any provision hereof, but such Affiliate
shall otherwise be considered a "Bank", and the assigning Bank
shall otherwise be considered to have disposed of any Loans so
assigned, for purposes hereof, including, without limitation,
paragraphs 3.1 and 12 hereof, and provided further, that the
Company shall not incur any additional expenses solely as a
result of such sale, assignment, transfer or negotiation.

     In addition, notwithstanding anything to the contrary
contained in this paragraph 14.6, any Bank may at any time or
from time to time assign all or any portion of its rights under
this Agreement with respect to its Loans, its Commitments and its
Notes to a Federal Reserve Bank.  No such assignment shall
release the assignor Bank from its obligations hereunder.

     No Bank shall, as between the Company and such Bank, be
relieved of any of its obligations hereunder as a result of
granting participations in all or any part of the Loans and the
Notes of such Bank or other obligations owed to such Bank.

     This Agreement shall be binding upon and inure to the
benefit of the Banks, the Agent and the Company and their
respective successors and assigns. All covenants, agreements,
warranties and representations made herein, and in  all
certificates or other documents delivered in connection with this
Agreement by or on behalf of the Company shall survive the
execution and delivery hereof and thereof, and all such
covenants, agreements, representations and warranties shall inure
to the respective successors and assigns of the Banks and the
Agent whether or not so expressed.


     The Agent shall maintain a copy of each assignment delivered
to it and a register or similar list for the recordation of the
names and addresses of the Banks and the Commitment Percentages
of the Banks and the principal amount of the Loans and the Notes
assigned from time to time. The entries in such register shall be
conclusive, in the absence of manifest error and provided that
any required consent of the Company has been obtained, and the
Company, the Agent and the Banks may treat each Person whose name
is recorded in such register as a Bank hereunder for all purposes
of this Agreement.  Upon each such recordation, the assigning
Bank




<PAGE>   45

                                   -40-


agrees to pay to the Agent a registration fee in the sum of One Thousand Five
Hundred Dollars ($1,500).

        14.7 APPLICABLE LAW. This Agreement and the Notes are being delivered
in and are intended to be performed in the Commonwealth of Massachusetts and
shall be construed and enforceable in accordance with, and be governed by, the
internal laws of the Commonwealth of Massachusetts without regard to principles
of conflict of laws.

        14.8 INTEREST. At no time shall the interest rate payable on the Notes,
together with the Facility Fee and the Agent's Fees, to the extent same are
construed to constitute interest, exceed the maximum rate of interest permitted
by law. The Company acknowledges that to the extent interest payable on the
Notes is based on FNBB's Prime Rate, such Rate is only one of the bases for
computing interest on loans made by the Banks, and by basing interest payable
on the Notes on FNBB's Prime Rate, the Banks have not committed to charge, and
the Company has not in any way bargained for, interest based on a lower or the
lowest rate at which the Banks may now or in the future make loans to other
borrowers.

        14.9 ACCOUNTING TERMS AND PRINCIPLES. All accounting terms not herein
defined by being capitalized shall be interpreted in accordance with GAAP,

ACKNOWLEDGES THAT NO REPRESENTATIVE OF THE AGENT OR THE BANKS OR COUNSEL TO THE
AGENT OR THE BANKS HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT THE AGENT OR
THE BANKS WOULD NOT, IN THE EVENT OF SUCH LITIGATION, SEEK TO ENFORCE SUCH
WAIVER. THE COMPANY ACKNOWLEDGES THAT THE AGENT AND THE BANKS HAVE BEEN INDUCED
TO ENTER INTO THE LOAN DOCUMENTS BY, INTER ALIA, THE PROVISIONS OF THIS
PARAGRAPH.

AN INCONVENIENT FORUM. THE COMPANY HEREBY AGREES THAT A FINAL JUDGMENT IN ANY
SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN ANY SUCH A COURT, AFTER ALL
APPROPRIATE APPEALS, SHALL BE CONCLUSIVE AND BINDING UPON IT.

        14.12     SERVICE OF PROCESS. PROCESS MAY BE SERVED IN ANY SUIT,

        14.13     NO LIMITATION ON SERVICE OR SUIT. NOTHING IN THE LOAN
DOCUMENTS, OR ANY MODIFICATION, WAIVER, OR AMENDMENT THERETO, SHALL AFFECT THE
RIGHT OF THE AGENT OR ANY BANK TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED
BY LAW OR LIMIT THE RIGHT OF THE AGENT OR ANY BANK TO BRING PROCEEDINGS AGAINST
THE COMPANY IN THE COURTS OF ANY OTHER JURISDICTION OR JURISDICTIONS.

        14.14     INCORPORATED PROVISIONS. Certain provisions of the Indenture

therein. Notwithstanding such incorporation, this Agreement may only be

                   FORM OF OPINION OF COUNSEL TO THE COMPANY


                                                                __________, 19__


TO THE PARTIES LISTED IN
SCHEDULE A ANNEXED HERETO

     Re:  Credit Agreement, dated as of December ___, 1993 among Boston Gas 
          Company, the signatory banks thereto and The First National Bank of 
          Boston, as Agent (the "Agreement")
          -------------------------------------------------------------------

        I have acted as counsel to Boston Gas Company, a Massachusetts
corporation (the "Company"), in connection with the authorization, execution
and delivery by the Company of the Agreement.

        This opinion is delivered to you pursuant to paragraph 5.4 of the
Agreement and the terms used herein which are defined in the Agreement shall
have the respective meanings set forth in the Agreement, unless otherwise
defined herein.

        In connection with this opinion, I have examined and am familiar with
originals or copies authenticated to my satisfaction of the Agreement and the
Notes, as executed and delivered by the Company, together with such corporate
documents and records of the Company, certificates of public officials and
officers of the Company and such other documents as I deemed necessary or
appropriate for the purposes of this opinion.

        Based upon and relying solely upon the foregoing, subject to the
comments and qualifications herein expressed and limited in all respects to the
laws of the Commonwealth of Massachusetts and the United States, I am of the
opinion that:

        1.     Each of the Company and each Subsidiary (i) is a corporation
duly organized, validly existing and in good standing under the laws of the
Commonwealth of Massachusetts and (ii) has all requisite corporate power and
authority to own its Property and to carry on its business as now conducted.
Each of the Company and each Subsidiary, is in good standing and duly qualified
to do business in each jurisdiction in which the failure to so qualify would

<PAGE>   52

                                     -2-


have a material adverse effect on the financial condition, Property, prospects
or operations of the Company and its Subsidiaries on a Consolidated basis.


        2.    The Company has full corporate power and authority to enter into,
execute, deliver and carry out the terms of the Agreement and to make the
borrowings contemplated thereby, to execute, deliver and carry out the terms of
the Notes, and to incur the obligations provided for therein and in the
Agreement, all of which have been duly authorized by all proper or necessary
corporate action on its part and are in full compliance with its Charter and
By-Laws.  No consent or approval of, or exemption by, shareholders or any
Governmental Body is required to authorize, or is required in connection with
the execution, delivery and performance of, the Agreement and the Notes, or is
required as a condition to the validity or enforceability of the Agreement and
the Notes, except for the approval of the DPU a certified copy of which has
been delivered as required under paragraph 5.6 of the Agreement, which approval
has been duly obtained and which is in full force and effect on the date hereof
and is final and not subject to appeal.

        3.    The Agreement constitutes, and the Notes, when issued and
delivered pursuant to the Agreement for value received, will constitute, the
valid and legally binding obligations of the Company enforceable against the
Company in accordance with their respective terms, except as such
enforceability may be limited by equitable principles (regardless of whether
such enforceability is considered in a proceeding in an equity or in an action
at law) and by applicable bankruptcy, insolvency, reorganization, moratorium or
similar laws affecting the rights of creditors generally.

        4.    To the best of my knowledge after due inquiry, and except for the
matters set forth in __________ of the Designated Documents, there are no
actions, suits or arbitration proceedings (whether or not purportedly on behalf
of the Company or any Subsidiary) pending or threatened against the Company or
any Subsidiary, or maintained by the Company or any Subsidiary, in law or in
equity before any Governmental Body, which if decided adversely to the Company
or such Subsidiary would result in a material adverse change in the financial
condition, Property or operations of the Company and its Subsidiaries on a
Consolidated basis, after giving effect to reserves reflected in the Financial
Statements or the footnotes thereto.  To the best of my knowledge after due
inquiry, there are no proceedings pending or threatened against the Company or
any Subsidiary which call into question the validity or enforceability of the
Agreement or the Notes.

        5.    To the best of my knowledge after due inquiry, except for the
matters set forth in ___________ of the Designated Documents, neither the
Company nor any Subsidiary is in default under any agreement to which it is a
party or by which it or any of its Property is bound the effect of which would
have a material adverse effect on the financial condition, Property, prospects
or operations of the Company and its Subsidiaries on a Consolidated basis.  No
provision of the Charter or By-Laws, and no provision of any existing mortgage,
indenture (including the Indenture), contract, agreement, statute (including,
without 

<PAGE>   53

                                   -3-


limitation, any applicable usury or similar law), rule, regulation, judgment,
decree or order binding on the Company or any Subsidiary would in any way
prevent the execution, delivery or carrying out of the terms of the Agreement
and the Notes, and the taking of any such action will not constitute a default
under, or result in the creation or imposition of, or obligation to create, any
Lien not permitted by paragraph 8.2 of the Agreement upon the Property of the
Company or any Subsidiary pursuant to the terms of any such mortgage,
indenture, contract or agreement.

        6.    Except as set forth in ____________ of the Designated
Documents, neither the Company nor any Subsidiary is in default with respect to
any judgment, order, writ, injunction, decree or decision of any Governmental
Body ap- plicable to the Company or such Subsidiary which default would have a
material adverse effect on the financial condition, property, prospects or
operations of the Company and its Subsidiaries on a Consolidated basis.  Except
as set forth in the Designated Documents, each of the Company and each
Subsidiary is complying in all material respects with all applicable material
statutes and regulations of all Govern- mental Bodies, including ERISA, a
violation of which would have a  material adverse effect on the financial
condition, Property, prospects or operations of the Company and each Subsidiary
on a Consolidated basis.

        7.    The Company is not an "Investment Company" as such term is
defined in the Investment Company Act of 1940, as amended.

        8.    The Company is not engaged principally, or as one of its
important activities, in the business of extending credit for the purpose of
purchasing or carrying any margin stock within the meaning of Regulation U of
the Board of Governors of the Federal Reserve System, as amended.  If used in
accordance with paragraph 2.12 of the Agreement, no part of the proceeds of the
Loans will be used (i) to purchase or carry any such margin stock, (ii) to
extend credit to others for the purpose of purchasing or carrying any margin
stock, (iii) for a purpose which violates the provisions of Regulations G, U
and X of the Board of Governors of the Federal Reserve System, as amended, or
(iv) for a purpose which violates any other law, rule or regulation of any
Governmental Body.

        9.   The Company and its Subsidiary are "subsidiaries" of a "holding
company" which is exempt under  the Public  Utility Holding Company Act of
1935, pursuant to orders of the Securi- ties and Exchange Commission,  which 
orders remain in full force and effect.

        10.  The Company has obtained all authorizations, approvals or
consents of and made all filings or registrations  with all Governmental Bodies
as are necessary to be obtained or made by the Company for the execution,
delivery or performance by the  Company of the Agreement and the Notes, and all
such authorizations, approvals and consents are in full force and effect.

        11.  A Massachusetts court of competent jurisdiction, in a
properly presented case, should uphold and give effect  to the  provisions  in
the Agreement and the Notes expressing 

<PAGE>   54

                                   -4-


the contractual choice of the parties thereto that such documents be 
construed in accordance with the laws of the Commonwealth of Massachusetts.

                              Very truly yours,

TO THE PARTIES LISTED IN
SCHEDULE A ANNEXED HERETO

     Re:  Credit Agreement dated as of December    , 1993 among BOSTON GAS 
          COMPANY, the signatory BANKS thereto and THE FIRST NATIONAL BANK OF 
          BOSTON, as Agent (the "Agreement")
          -------------------------------------------------------------------

        We have acted as the Agent's Special Counsel in connection with the
Agreement. Terms used herein which are defined in the Agreement shall have the
same meanings as therein defined, except as otherwise set forth herein.

        We have examined originals or copies of the following documents:

        1.   The Agreement, executed by each of the parties thereto.

        2.   The Revolving Credit Notes, executed by the Company and payable to
the order of the respective Banks.

        3.   The opinion of General Counsel to the Company dated the date
hereof.

        4.   The other documents furnished by the Company pursuant to paragraph
5 of the Agreement.

        As to all matters of fact (including factual conclusions and
characterizations and descriptions of purpose, intention or other state of
mind), we have relied entirely upon (i) the representations of the Company set
forth in paragraph 4 of the Agreement and (ii) certificates delivered to us by
the management of the Company, and have assumed, without independent inquiry,
the accuracy of those representations and certificates.  We have assumed the
genuineness of all signatures, the conformity to the originals of all documents
reviewed by us

as copies, the authenticity and completeness of all original documents
reviewed by us in original or copy form and the legal competence of each
individual executing any document.

        We have also relied upon the opinion referred to in item 3 above,
without making any independent investigation with respect thereto.

        We understand that all of the foregoing assumptions and limitations are
acceptable to you.

        Subject to the limitations set forth below, we have made such
examination of law as we have deemed necessary for the purposes of this
opinion.  This opinion is limited solely to the laws of the Commonwealth of
Massachusetts as applied by courts located in the Commonwealth of
Massachusetts, and the federal laws of the United States of America, to the
extent that the same may apply to or govern such transactions.

        Based upon the foregoing, we are of the opinion that the documents
listed above furnished pursuant to the provisions of paragraph 5 of the
Agreement are substantially responsive to the requirements of the Agreement.

        This opinion is furnished to the addressees hereof and is solely for the
benefit of such addressees and for the benefit of any financial institutions
which become "Banks" pursuant to Section 14.6 of the Agreement subsequent to the
date hereof. This opinion speaks only as of its date and we assume no
responsibility to update it for any change of law or any facts of which we may
become aware.  This opinion may not be relied upon by any other person or
entity.


                              Very truly yours,
