ITEM 1.  BUSINESS
 
THE COMPANY
 
     Bay State Gas Company ("Bay State" or the "Company") was incorporated in
1974 as a Massachusetts corporation. However, Bay State's predecessor companies'
operations began in 1847, and consecutive quarterly dividends have been paid by
these entities or Bay State since 1853. The Company is primarily a gas
distribution utility that provides local transportation service in the Brockton,
Lawrence, and Springfield, Massachusetts areas. Additionally, the Company also
offers additional energy products and services to its customers, including
commodity sales of natural gas, and invests in energy ventures. Approximately
95% of all revenues are generated from providing local transportation and
natural gas sales with 84% of these annual revenues coming from the Company's
Massachusetts service area. Bay State has five subsidiaries within its corporate
organization. Northern Utilities, Inc. ("Northern") is a gas distribution
utility operating in the Portland and Lewiston areas in Maine and the Portsmouth
area in New Hampshire. Granite State Gas Transmission, Inc. ("Granite") is an
interstate gas transmission and supply company operating in the states of Maine,
New Hampshire, Massachusetts, and Vermont. Granite has four wholly owned
subsidiaries, Bay State Energy Development, Inc., which owns an equity interest
in the MASSPOWER cogeneration partnership, Natural Gas Development Corp., a
corporation established to invest in the Portland Natural Gas Transmission
System ("PNGTS"), a proposed natural gas transmission pipeline in northern New
England, Bay State Energy Enterprises, Inc., which owns a equity interest in KBC
Energy Services, a partnership which markets natural gas supplies and
energy-related services on a nonregulated basis to commercial and industrial
end-users and Energy Asset Funding Inc., a corporation established to provide
financing for energy-related equipment.
 
     Natural gas sales in New England are seasonal, and the Company's results of
operations reflect this seasonality. Accordingly, results of operations are
typically most favorable in the second quarter of the Company's fiscal year
(three months ended March 31), with results of operations being next most
favorable in the first quarter, while losses are commonly incurred in the third
and fourth quarters. The quarterly operating results for 1995 and 1994 are
described further in Note 9 of "Notes to Consolidated Financial Statements,"
Part II, Item 8, FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA.
 
     The Company's customers generally are billed monthly on a cycle basis in
therms. One therm equals 100,000 British thermal units (1 Btu), the heat content
of approximately 100 cubic feet of gas. 1,000,000 Btu (1 MMBtu), or ten therms
are the energy equivalent of approximately 1,000 cubic feet of natural gas or
7.14 gallons of home heating oil.
 
LOCAL TRANSPORTATION MARKETS AND COMPETITION
 
     In 1995, 97% of Bay State's customers purchased bundled local
transportation and natural gas and the remaining 3% elected to purchase
unbundled local transportation. The tables below show the net change in
transportation customers and throughput volumes for the past three years.

</TABLE>
 
     The Company's principal competitors are unregulated fuel-oil retailers and
regulated electric utilities. Increases in demand for natural gas are primarily
driven by the rate of economic growth and new construction within the Company's
service territories, and by the marketing and pricing of competing fuels.
 
     In the residential market, the Company should continue to benefit from the
New England region's market and growth potential. There are approximately
150,000 households along the Company's mains and additional homes located short
distances from existing gas mains that use no gas at all. In addition, the
Company anticipates additional growth from the estimated 44,000 existing
residential nonheating customers. These are attractive markets for the Company
and represent an opportunity to increase gas sales with little or no capital
investment.
 
     For commercial and industrial customers, environmental issues are an
important issue in choosing an energy source. Since natural gas is the cleanest
burning fossil fuel, using natural gas can assist companies in complying with
the Clean Air Act and underground oil storage tank legislation.
 
     Finally, the Company markets gas to large users on a seasonal or
interruptible basis. Approximately 59% of these interruptible volumes in 1995
were sold to five electric utilities for electric power generation. The
remainder were sold to approximately 110 industrial customers equipped to burn
either natural gas or fuel oil. Price is the key competitive factor in this
market, and the Company pursues interruptible sales through a flexible pricing
structure designed to remain competitive with other fuels. Substantially all net
margins from interruptible sales are passed back to firm customers through cost
of gas adjustment clauses (see "Rates and Regulations").
 
NATURAL GAS SALES
 
     The natural gas sales portion of the Company's bundled service does not
currently provide a profit margin. However, as all but 85 of the Company's
287,000 local transportation customers purchase bundled transportation and
natural gas, minimizing gas costs is an important part of the Company's
business.
 
     The Company's strategy of balancing gas purchase costs and security of
supply is achieved by optimizing the mix and terms of natural gas contracts with
the use of supplemental liquefied natural gas and propane to meet peak winter
demand. The Company maintains a diversified gas supply portfolio of domestic and
Canadian gas supply contracts with producers.
 
CAPACITY REQUIREMENTS
 
     Bay State has capacity contracts for the transmission of natural gas to its
distribution system from the producing areas of North America. The Company
currently transports natural gas from Canada through a converted oil pipeline
leased from the Portland Pipe Line Corporation ("PPLC"). The PPLC lease
currently extends to March 31, 1997. An agreement with PPLC to extend the lease
through the 1997-1998 heating season is being sought. Short-term contingency
plans have been developed for supplying customers in Maine and New Hampshire
through the 1997-1998 heating season in the event that the lease is not
extended. Long-term, two projects to replace the pipeline capacity provided by
the PPLC lease are being pursued, a 2.0 million MMBtu liquefied natural gas
storage facility in Wells, Maine, and PNGTS. For further discussion of these

Item 8, FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA.
 
REGULATION AND RATES
 
     The Company and its subsidiaries, are subject, where applicable, to
regulation by the Massachusetts Department of Public Utilities ("MADPU"), the
New Hampshire Public Utilities Commission ("NHPUC"), the Maine Public Utilities
Commission ("MPUC") and the Federal Energy Regulatory Commission ("FERC") with
respect to rates, adequacy of service, issuance of securities, accounting, and
other matters.
 
     The tariff schedules of the local distribution companies provide for
declining block rates which result in reductions in the unit price as usage
increases, and for seasonal rates that charge customers more per unit for gas
purchased during the high-demand winter heating season and less per unit during
summer months. These schedules also contain cost of gas adjustment ("CGA")
clauses that permit the distribution companies to pass on to firm customers
increases or decreases in recovered natural gas costs. Substantially all gas
supplier refunds and profits from interruptible sales are returned to firm
customers through the CGA clauses.
 
     As a result of a third party fuel inventory financing program instituted by
the Company in 1982, fuel inventory and the related administrative and carrying
costs are also recovered through the CGA clauses. In addition, the MADPU allows
recovery of the following through the CGA: 1) the working capital costs
associated with purchased gas costs; 2) clean-up costs associated with waste
materials from former gas manufacturing sites; and 3) costs associated with
MDPU-approved energy conservation and load management programs.
 
     The Company offers special contracts to large volume industrial customers
in its Massachusetts service area and natural gas transportation service to
industrial end-user customers in both its Massachusetts and New Hampshire
jurisdictions. Contracts for such service are individually filed with and
approved by the MADPU and NHPUC and are in effect for specified periods of time.

FRANCHISES
 
     The utility franchise rights of the Company are non-exclusive. Competition
from other companies in the distribution of gas, however, is restricted without
prior approval of the applicable local and state governmental agencies.
 
     The laws of the Commonwealth of Massachusetts permit a municipality, by

RESULTS OF OPERATIONS
 
  Year In Review
 
     During 1995, Bay State Gas Company ("Bay State" or the "Company") continued
to respond to the changing energy industry while experiencing warmer than normal
weather. During 1995, the weather was 11% warmer than the prior year and 6%
warmer than normal within the Company's service territories. The following table
displays the degree days for the past three years:

</TABLE>
 
     Bay State responded to the warmer weather by implementing several cost
saving and service-related program improvements that not only minimized the
impact of the weather on net income for 1995, but will also positively impact
earnings in future years.

     Net income was $23.1 million in 1995 compared to $24.5 million in 1994, and
earnings per share were $1.71. This compares to $1.85 one year ago. The common
stock dividends declared in 1995 were $1.48 per share, 2.8% higher than the
prior year. This was the twelfth consecutive year of increased common stock
dividends, and it completes the 142nd year of consecutive quarterly dividends.
The current annualized dividend is equivalent to $1.50 per share.

</TABLE>
 
     The majority of Bay State's customers purchase bundled local transportation
and natural gas. Some larger commercial and industrial customers have elected to
purchase unbundled local transportation, requiring them to now manage their own
gas purchasing, balancing, and storage functions.
 
     Local transportation revenues decreased 3.6% from 1994 to 1995. This
decrease in revenues was primarily attributable to the warmer weather
experienced in the Company's service territories during 1995, which reduced
transportation, or throughput, to firm customers. The 11% change in weather from
year to year would have resulted in a $7.1 million decrease in transportation
revenues. However, the Company added almost 6,500 customers in 1995, up from
4,800 and 5,800 in 1994 and 1993, respectively. This 2.3% growth in the customer
base somewhat offset the negative impact of the weather on revenues.
 
     Additionally, total system throughput increased from 77.8 million MMBtu in
1994 to 84.0 million MMBtu in 1995 as the Company utilized its capacity during
the warmer weather by supplying additional volumes to interruptible customers.
The profit margins from these customers are passed back to the Company's firm
customers through reduced gas costs.
 
  Natural Gas Sales
 
     The natural gas sales portion of the Company's bundled service does not
currently provide a profit margin. However, as all but 85 of the Company's
287,000 local transportation customers purchase bundled local transportation and
natural gas, minimizing gas costs is an important part of the Company's
business.
 
     The Company's strategy of balancing gas costs and security of supply is
achieved by optimizing the mix and terms of natural gas contracts with the use
of supplemental liquefied natural gas and propane to meet peak winter demand.
The Company maintains a diversified gas supply portfolio of domestic and
Canadian gas supply contracts with producers.
 
     The Company's rates include cost of gas adjustment clauses ("CGA") pursuant
to which natural gas purchase costs and other costs are recovered from
customers. The following table details these costs:

     Recovered natural gas costs decreased by 15%, or $41.6 million, in 1995.
This decrease was the result of a decline in purchase costs combined with
decreases in supplemental fuel costs, demand-side management program ("DSM")
costs, and transition costs. The decrease in purchase costs reflect a
combination of the effect of the new competitive gas supply environment and the
impact of the warm weather on demand. The decrease in supplemental fuel costs
also reflect the warmer weather, as well as renegotiated contracts with
supplemental fuel suppliers. DSM programs are aimed at motivating customers to
use natural gas responsibly and, at the same time, cost the Company less than
the incremental gas supply these customers would have used otherwise. As these
programs have become fully implemented, their costs to customers have been
reduced.
 
     The Federal Energy Regulatory Commission ("FERC") is permitting gas
pipeline companies, including those from which the Company purchases a
significant portion of its natural gas supplies and storage services, to bill
their customers for prudently incurred costs of transitioning into the
deregulated environment. These costs significantly declined in 1995 and should
continue to decline in the future. The Company has regulatory approval to
recover these costs through the CGA.

     As is the case with revenues generated from local transportation, propane
revenues are also significantly impacted by the weather. However, in 1995, the
Company was able to expand its propane business to compensate for the
weather-related decrease in demand. Sales volumes for propane increased from 6.8
million gallons in 1994 to 7.4 million gallons in 1995.
 
     Revenues from equipment rentals and service increased by over 21% or $2.2
million in 1995 after increasing by 7% and 4% in 1994 and 1993, respectively.
This significant increase in 1995 is primarily the result of moderate price
increases and new service offerings combined with an increase in the number of
units rented and serviced.
 
  Operating Expenses
 
     Operations expenses decreased by $3.9 million in 1995 after decreasing by
$1.5 million in 1994 and increasing by $7.5 million in 1993. As the result of
lower accounts receivable balances and improved collections from customers
through special payment arrangements, bad debt expense was reduced by $2.5
million in 1995. The remaining decrease reflects other cost control measures.
 
     Higher plant balances, an outcome of customer growth, have resulted in
continuing increases in depreciation expense. Taxes, other than income taxes,
increased primarily due to higher property taxes. Annual increases in property
tax rates and assessments, combined with the growth in plant, increased property
taxes by $601,000, $808,000, and $821,000 in 1995, 1994, and 1993, respectively.

</TABLE>
 
Bay State has operating results from two investments in energy ventures:
MASSPOWER, a cogeneration facility, and KBC Energy Services ("KBC"), a
partnership with Connecticut Natural Gas Corporation and Koch Gas Services
Company, which markets natural gas supplies and energy-related services on a
nonregulated basis to commercial and industrial end-users.
 
  Interest Expense and Dividend Requirements on Preferred Stock
 
     In 1995, the Company incurred additional interest expense due to
overcollections of recovered natural gas costs, a result of lower than
forecasted wellhead costs, and higher than anticipated pipeline supplier
refunds. Dividend requirements on preferred stock were relatively flat for the
comparative periods.
 
  Results of Operations, 1994 and 1993
 
     Net income increased $1.7 million and $4.4 million in 1994 and 1993,
respectively. In both years the Company experienced colder than normal weather
and had a growing customer base. The 1993 net income increase also reflected the
result of a rate increase in the Company's Massachusetts service area.
 
     Operating revenues for 1994 and 1993 increased by $50.9 million and $39.6
million, respectively. In both years, this growth was primarily due to customer
additions, combined with an increase in the cost of gas and the colder weather.
The increase in 1993 operating revenues also reflected the Massachusetts rate
increase, which was effective in November 1992. Recovered natural gas costs
increased 17.6% and 9.3% in 1994 and 1993, respectively. The 1994 increase was
the result of higher combined purchase and transmission costs, and additional
increases in supplemental fuel costs, DSM program costs, and transition costs
while the 1993 increase was primarily the result of higher natural gas commodity
prices both under long-term contracts and from the spot market. These costs
represent a bundled product and transmission cost for most of 1993.
 
     Operations expenses decreased by $1.5 million in 1994, after increasing by
$7.5 million in 1993. The decrease was the net result of the absence of costs
related to the union work stoppages, which occurred in 1993, and higher bad debt
expense related to the colder winter weather experienced in 1994. Also
contributing to the decrease in 1994 operations expenses was the effect of an
internal review of operations and corporate structure performed early in 1994.
This review resulted in a flatter, more efficient organization requiring almost
5% fewer employees. The largest increases in operating expenses in 1993 were in
employee benefits and outside services. The higher employee benefit expenses in
1993 included an increase in postretirement benefit costs, resulting from the
implementation of Statement of Financial Accounting Standards No. 106, and the
establishment of an accrual for an employee severance plan. Outside services
included an abnormal level of costs related to the union work stoppages and
regulatory restructuring costs.
 
     Interest expense increased $2.2 million in 1994 due to higher levels of
long-term debt outstanding during the year, higher short-term debt rates, and a
decrease in the debt portion of AFUDC. Total interest expense for 1993 was
comparable to the prior year.
 
  Liquidity and Capital Resources
 
     Natural gas sales in New England are seasonal, and the Company's cash flows
reflect this seasonality. Approximately 74% of annual revenues are generated
during the heating season, which results in a high level of cash flow from
operations from late winter through early summer. Short-term borrowings are
typically highest in the fall and early winter as a result of completion of the
annual construction program and seasonal
 
                                       11

working capital requirements. The Company has been able to access the financial
markets to meet its capital requirements and does not anticipate a change in its
access to, or the availability of, capital in the coming year.

        Net cash provided by operating activities........  $ 73.7      $ 66.1      $ 15.6
</TABLE>
 
     Cash flows from operations improved by $7.6 million in 1995 despite a
decrease in net income primarily as the result of decreasing accounts receivable
balances, increases in refunds due customers, and lower cash contributions to
benefit plans. Refunds from upstream pipelines totaled approximately $15.8
million in 1995 as compared to $9.4 million in 1994. This amount will be
refunded to customers in the near future, contributing to reduced gas prices.
The Company made cash contributions to its benefit plans of $3.2 million, $15.3
million, and $15.0 million in 1995, 1994, and 1993, respectively.

</TABLE>
 
     The Company invests in property, plant, and equipment to improve and
protect its distribution system, and to expand its system to meet customer
demand. As a result of planned spending, capital expenditures for property,
plant, and equipment increased $2.1 million in 1995. Capital expenditures for
1996 are estimated to be approximately $53.0 million.
 
     The remaining increase in investing activities for 1995 relates to
expenditures on energy ventures. These expenditures were $4.6 million, $1.0
million, and $4.8 million in 1995, 1994, and 1993, respectively. In 1993, a
one-time equity investment was made in MASSPOWER of $4.2 million. Capital
expenditures for energy ventures for 1996 are estimated to be approximately $6.3
million (see note 8).

  Cash flows from financing activities
 
<CAPTION>
        In millions                                         1995        1994        1993

        Net cash provided by (used in) financing
          activities.....................................  $(17.0)     $(11.2)     $ 35.8
</TABLE>
 
     As was the case in 1994, the 1995 decline in cash flows from financing
activities reflects a reduction in debt issuances as a result of strong cash
flows from operations. The Company has a shelf registration statement covering
up to $125.0 million of senior unsecured debt securities, under which $65.0
million in notes has been issued as of September 30, 1995. The Company has
access to $77.0 million in bank lines of credit. In early 1995, the Dividend
Reinvestment Plan was converted to a market purchase plan, eliminating new
equity issuances under this plan.
 
     The Company is in the final stages of completing a sale and lease-back
arrangement for equipment rental assets with a financing company, through which
approximately $20.7 of additional capital will be made available. This, along
with continuing strong operating cash flows, will enable the Company to fund its
operating and investing activities without extensive long-term debt or equity
issuances in 1996.
 
  Impact of Inflation
 
     The rates charged to transportation customers may not be increased without
formal proceedings before regulatory authorities. Accordingly, in the absence of
authorized rate increases and except for changes in recovered gas costs, which
are reflected in customer rates, the Company must look to performance
improvements and higher sales volumes, particularly from highly profitable
market segments, to offset inflationary increases in its costs of operations.
Current rates only permit the Company to recover its historical cost of utility
plant and give no recognition to the current cost of replacing facilities.
Although no new material
 
                                       12
<PAGE>   13
 
rate proceedings are currently planned, under the current regulatory process,
management believes the cost of utility plant additions will be recognized in
setting future rate levels.
 
  Environmental Issues
 
     The Company continues to work with federal and state environmental agencies
to assess the extent and environmental impact of waste materials that exist at
or near former gas manufacturing sites located primarily in Massachusetts. The
costs of such assessments and any related remediation determined to be necessary
will be funded from traditional sources of capital and recovered from customers
(see note 8).
 
  New Accounting Standard
 
     In March 1995, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 121 ("SFAS 121"), "Accounting
for the Impairment of Long-Lived Assets and Long-Lived Assets to be Disposed
Of." This statement, which is effective for years beginning after December 15,
1995, requires the Company to review long-lived assets for impairment whenever
events or changes in circumstances indicate that the carrying amount of an asset
may not be recoverable. The Company does not expect that the adoption of this
standard will have a material impact on the results of operations, financial
condition, or cash flows of the Company.

                             BAY STATE GAS COMPANY
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                       SEPTEMBER 30, 1995, 1994, AND 1993
 
NOTE 1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     PRINCIPLES OF CONSOLIDATION.  The consolidated financial statements include
the accounts of Bay State Gas Company and its wholly owned subsidiaries (the
"Company"). All significant intercompany transactions and accounts have been
eliminated. Certain information in the prior period financial statements has
been reclassified to conform with the current period's presentation.
 
     REGULATION AND OPERATIONS.  The Company is subject to regulation with
respect to rates, accounting and other matters, where applicable, by the
Massachusetts Department of Public Utilities ("MADPU"), the New Hampshire Public
Utilities Commission, the Maine Public Utilities Commission, and the FERC. The
Company's accounting policies conform to generally accepted accounting
principles and reflect the effects of the ratemaking process in accordance with
Statement of Financial Accounting Standards No. 71, "Accounting for the Effects
of Certain Types of Regulation."
 
     PLANT.  Plant is stated at original cost and consists of utility plant and
non-utility plant assets. The original cost of depreciable units of plant
retired, together with the cost of removal, net of salvage, is charged to
accumulated depreciation. The costs of maintenance, repairs, and replacements of
minor items are charged to expense as incurred.
 
     Depreciation is provided for all classes of plant on a group straight-line
basis in amounts equivalent to overall composite rates of 3.88% for 1995 and
1994 and 3.74% for 1993.
 
     ALLOWANCE FOR FUNDS USED DURING CONSTRUCTION (AFUDC).  AFUDC is the
estimated cost of funds used for construction purposes. Such allowances are
charged to plant and reported as other income (cost of equity funds) or a
reduction of interest expense (cost of borrowed funds). AFUDC was $748,000,
$457,000, and $2,028,000 for 1995, 1994, and 1993, respectively.
 
     INVESTMENTS.  The Company accounts for its partnership investments by the
equity method.
 
     CASH AND TEMPORARY CASH INVESTMENTS.  The Company considers all highly
liquid debt instruments purchased with an original maturity of three months or
less to be cash equivalents.
 
     LOCAL TRANSPORTATION, NATURAL GAS SALES, AND DEFERRED GAS COSTS.  Local
transportation revenue and natural gas sales are based on the volume of gas
transported or sold at billing rates authorized by regulatory authorities and
include unbilled revenues for gas delivered, but not billed. The Company's rates
include cost of gas adjustment clauses pursuant to which gas and certain other
costs are recovered from customers. Any differences between gas costs incurred
and amounts billed are deferred for recovery from or refund to customers in
future periods. Also included in natural gas sales are sales to interruptible
customers. Substantially all net margins from interruptible sales are used to
reduce gas costs to customers through the cost of gas adjustment clauses.
 
     ENVIRONMENTAL COSTS.  In accordance with orders of regulatory authorities,
the Company defers costs incurred to remediate environmental damage. Such costs
are amortized to expense over periods of seven to 10 years as they are recovered
from customers (see note 8).
 
     INCOME TAXES.  On October 1, 1993, the Company adopted the asset and
liability method of accounting for income taxes as required by Statement of
Financial Accounting Standards No. 109 ("SFAS 109"), "Accounting for Income
Taxes." Pursuant to SFAS 109, deferred tax assets and liabilities are recognized
for the future tax consequences attributable to differences between the tax
bases and the financial statement carrying amounts of existing assets and
liabilities. Prior year financial statements reflect deferred income taxes for
the tax effects of the timing differences between the recognition of revenue and
expense for income tax purposes and financial reporting purposes (see note 2).
 
                                       19
<PAGE>   20
 
     Investment tax credits related to plant additions prior to 1987 were
deferred and are being amortized as reductions of income tax expense over the
lives of the related assets.
 
     PENSION AND OTHER EMPLOYEE BENEFIT PLANS.  The Company has noncontributory
defined benefit pension plans covering substantially all employees. Benefits
under the plans are generally based on years of service and the level of
compensation during the final years of employment. Pension costs are recognized
on the accrual method of accounting over the expected periods of employee
service based on actuarial assumptions.
 
     Statements of Financial Accounting Standards No. 106, "Employers'
Accounting for Postretirement Benefit Plans Other than Pensions" and No. 112,
"Employers' Accounting for Postemployment Benefits," were adopted on October 1,
1993, requiring the accrual method of accounting for the costs of postretirement
and postemployment benefits. Other postretirement benefits consist of certain
health and life insurance benefits for retired and active employees hired before
September 30, 1990. Postemployment benefits consist of workers compensation
claims, long-term disability payments, and medical coverage continuation
payments. These costs were previously recognized when paid. They are now accrued
over the expected periods of employee service based on actuarial assumptions
(see note 7).
 
     EARNINGS PER SHARE.  Earnings per common share have been computed by
dividing earnings applicable to common stock by the weighted average number of
shares of common stock outstanding during each year.
 
     NEW ACCOUNTING STANDARDS.  Effective for fiscal years beginning after
December 15, 1995, SFAS 121 will require a review of long-lived assets for
impairment whenever events or changes in circumstances indicate that the
carrying amount of an asset may not be recoverable. It is expected that the
adoption of this standard will not have a material impact on cash flows,
financial condition, or the results of operations.

     At September 30, 1995 and 1994, unamortized deferred investment tax credits
included in long-term deferred taxes amounted to $5.8 million and $6.2 million,
respectively.
 
     As discussed in note 1, a new method of accounting for income taxes was
adopted as of October 1, 1993. The cumulative effect on the years prior to
October 1, 1993 of adopting the new method of accounting for income taxes had no
effect on net income because a regulatory asset of $9.6 million was recorded,
reflecting future amounts due from customers for the effects of the temporary
differences. The effect of the change on income tax expense for 1994 was not
significant because amounts of income tax expense which differ from amounts
calculated in accordance with currently effective rate orders for settlement
with customers in future periods have been deferred.

     COMMON STOCK.  A Key Employee Stock Option Plan provided for the granting
of options to key employees to purchase an aggregate of 1,050,000 shares of
common stock. While it is anticipated that no further options will be granted
under this plan, previously granted options may continue to be exercised through
2002.

     A Shareholder Rights Plan provides one right ("Right") to buy one share of
common stock at a purchase price of $70 for each share of common stock issued
and to be issued. The Rights expire on November 30, 1999 and only become
exercisable, or separately transferable, 10 days after a person or group
acquires, or announces an intention to acquire, beneficial ownership of 20% or
more of the Company's common stock. The Rights are redeemable by the Board at a
price of $.01 per Right, at any time prior to the acquisition by a person or a
group of beneficial ownership of 20% or more of the Company's common stock. Once
a person or group acquires more than 20% of the Company's common stock, however,
the Rights may not be redeemed.
 
     At September 30, 1995, there were 385,000 authorized but unissued shares of
common stock reserved for the Dividend Reinvestment Plan ("DRP"). On December 1,
1994, the DRP was converted to a market based plan. It is anticipated that no
further shares will be issued under this plan.
 
     CUMULATIVE PREFERRED STOCK AND LONG-TERM DEBT.  The cumulative preferred
stocks rank equally and are preferred over common stock in voluntary liquidation
at the redemption price in effect at the time of such voluntary liquidation and
in involuntary liquidation at the par value per share, in each case plus accrued
dividends, except for the $3.80 Series, $50 par value, which has a voluntary
liquidation value of $83 per share and a set involuntary liquidation value of
$81.50 per share, plus accrued dividends.

     The fair values of capital lease obligations are estimated using the
present value of the minimum lease payments discounted at market rates. The fair
values of long-term debt are estimated based on current rates offered to the
Company for debt of the same remaining maturities. The carrying amounts for cash
and temporary cash investments, accounts receivable, accounts payable, accrued
liabilities, and short-term debt approximate their fair values due to the
short-term nature of these instruments.

NOTE 6.  FUEL PURCHASE AGREEMENTS
 
     Up to $30.0 million can be raised through credit agreements (the
"Agreements") underlying the Fuel Purchase Agreements with a corporation
established to provide financing, through borrowing on a demand basis or selling
supplemental gas inventories. Any inventories sold must be repurchased and any
associated carrying costs paid when the gas is withdrawn from storage. All gas
costs, carrying costs, and administrative charges are fully recoverable through
the CGA approved in each state regulatory jurisdiction. The Agreements contain
an expiration date of September 1998.

     POSTRETIREMENT BENEFITS OTHER THAN PENSIONS.  As described in note 1, the
Company adopted the accrual method of accounting for postretirement benefit
plans other than pensions in 1994. The change in the method of accounting had no
significant impact in 1994 as regulatory authorities permit the Company to defer
costs in excess of amounts recovered through rates for collection in future
periods. The present value of the accumulated benefit obligation was $24.7
million and $28.2 million, at September 30, 1995 and 1994, respectively. The
expense recognized was $2.7 million, $2.8 million, and $2.5 million for 1995,

     Plan assets are held in voluntary employee benefit association ("VEBA")
trusts and medical funds in the pension plans. VEBA assets are invested in
common stocks, bonds, and cash equivalents.
 
     The accumulated other postretirement benefit obligation was determined
using an assumed discount rate of 8.0% and an expected long-term pre-tax rate of
return on plan assets of 9.0% for both 1995 and 1994, and a health care cost
trend rate of 9.0% and 11.0% in 1995 and 1994, respectively, decreasing to 6.0%
by 1998. An annual 1% increase in the health care cost trend rate would increase
the accumulated postretirement benefit obligation by $2.2 million and the cost
for 1995 by $300,000.
 
     RETURN ON PREPAYMENTS OF OTHER POSTRETIREMENT BENEFITS.  As permitted by
regulatory authorities, noncash returns of $1,650,000, $857,000, and $286,000
for 1995, 1994, and 1993, respectively, have been recorded on amounts of
prepayments associated with employee postretirement benefit plans other than
pensions. Regulators permit the accrual of returns on these prepayments because
the plan funding will significantly reduce future costs of the plans.
 
     POSTEMPLOYMENT BENEFITS OTHER THAN PENSIONS.  As described in note 1, the
accrual method of accounting for postemployment benefit plans was adopted in
1994. The change in the method of accounting had no significant impact in 1994
as the Company deferred costs in excess of amounts recovered through rates for
collection in future periods. The present value of the accumulated benefit
obligation was $4.9 million and $4.1 million, at September 30, 1995 and 1994,
respectively.
 
     EMPLOYEE SAVINGS PLAN.  Employee Savings Plans (the "ESP's") provides
eligible employees with an incentive to save and invest regularly. The ESP's are
defined contribution plans, which allow eligible employees to defer a portion of
their salaries to employee-funded pretax retirement savings accounts. Matching
contributions to certain employee deferrals were $813,000, $784,000, and
$601,000 in 1995, 1994, and 1993, respectively.
 
NOTE 8.  COMMITMENTS AND CONTINGENCIES
 
     CAPACITY REQUIREMENTS.  The Company currently transports natural gas from
Canada through a converted oil pipeline leased from the Portland Pipe Line
Corporation ("PPLC"). The PPLC lease currently extends to March 31, 1997. An
agreement with PPLC to extend the lease through the 1997-1998 heating season is
being sought. Short-term contingency plans have been developed for supplying
customers in Maine and New Hampshire through the 1997-1998 heating season in the
event that the lease is not extended. Long-term, two projects to replace the
pipeline capacity provided by the PPLC lease are being pursued, a 2.0 million
MMBtu liquefied natural gas storage facility in Wells, Maine ("Wells LNG"), and
the Portland Natural Gas Transmission System ("PNGTS").

</TABLE>
 
     PNGTS is an interstate pipeline that will extend 250 miles from the
US-Canadian border to the New Hampshire-Massachusetts border. By March 1, 1996,
PNGTS plans to file an application with the FERC for approval to construct and
operate the pipeline. The Company has entered into long-term agreements with
PNGTS for service on the pipeline. Such agreements are subject to state
regulatory review and approval in Massachusetts, Maine, and New Hampshire. In
November 1994, the Company filed an application with the FERC for approval to
construct and operate Wells LNG. The Company will file for approval from the
public utility commissions of Maine and New Hampshire of its agreement for
service from the LNG facility.
 
     Recovery of investments in PNGTS and Wells LNG is dependent upon, among
other things, successful completion of the projects and the terms of required
regulatory approvals. While their completion is subject to a number of factors
beyond the Company's control, the Company believes that these projects will be
successful. Both of these projects are scheduled to be completed and available
for service by November 1998.
 
     During 1995, the Company made an initial investment of $50,000 in KBC and
is committed to invest up to a total of $1.7 million. KBC began operations in
1995.
 
     LONG-TERM OBLIGATIONS.  The Company has long-term contracts for the
purchase, storage, and delivery of gas supplies. Certain of these contracts
contain minimum purchase provisions which, in the opinion of management, are not
in excess of the Company's requirements.
 
     ENVIRONMENTAL ISSUES.  Like other companies in the natural gas industry,
the Company is party to governmental actions associated with former gas
manufacturing sites. Management estimates that, exclusive of insurance
recoveries, if any, expenditures to remediate and monitor known environmental
sites will range from $3.9 million to $10.0 million. Accordingly, a $3.9 million
liability, with an offsetting charge to a regulatory asset (see note 1), has
been accrued. Environmental expenditures for 1995, 1994, and 1993 were $387,000,
$129,000, and $620,000, respectively. Exclusive of amounts accrued for future
expenditures, at September 30, 1995 and 1994, approximately $3.0 million of
environmental expenditures had been deferred for future recovery from customers.
 
     REGULATORY MATTERS.  On April 13, 1995, approval was received from the FERC
for a $1.1 million increase in annual pipeline revenues effective November 1,
1994.
 
     An overall revenue-neutral rate redesign has been filed with the MADPU. The
goal of the rate redesign is to implement rates that more closely reflect the
actual costs associated with serving different customers. New rates are expected
to be effective early in calendar 1996.
 
     Significant regulatory assets arising from the rate-making process
associated with income taxes, employee benefits, and environmental response
costs have been recorded. Based on its assessments of decisions by regulatory
authorities, management believes that all regulatory assets will be settled at
recorded amounts through specific provisions of current and future rate orders.
 
     LITIGATION.  The Company is involved in various legal actions and claims
arising in the normal course of business. Based on its current assessment of the
facts of law, and consultations with outside counsel, management does not
believe that the outcome of any action or claim will have a material effect upon
the consolidated financial position, results of operations, or liquidity of the
Company.

                              REPORT OF MANAGEMENT
 
     The management of Bay State Gas Company and its subsidiaries has the
responsibility for preparing the accompanying financial statements. We believe
the financial statements were prepared in conformity with generally accepted
accounting principles. Management also prepared the other information in the
annual report and is responsible for its accuracy and consistency with the
financial statements.
 
     To fulfill its responsibility, management maintains a system of internal
control that has been designed to provide reasonable assurance as to the
integrity and reliability of the financial statements and the safeguarding of
Company assets.
 
     The Company has established statements of corporate policy relating to
conflict of interest and conduct of business and annually receives from
appropriate employees confirmation of compliance with these policies.
 
     The Company's financial statements have been audited by KPMG Peat Marwick
LLP, independent certified public accountants. The independent accountants are
elected by the Company's Directors and report any recommendations concerning the
Company's system of internal control to the Audit Committee of the Board of
Directors, which consists of three outside Directors. The Audit Committee meets
periodically with management, internal auditors and KPMG Peat Marwick LLP, to
review and monitor the Company's financial reporting, accounting practices, and
business conduct.
 
     Although there are inherent limitations in any system of internal control,
management believes that as of September 30, 1995, the Company's system of
internal control was adequate to accomplish the objectives discussed herein.

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors and Shareholders of
  BAY STATE GAS COMPANY
 
     We have audited the accompanying consolidated balance sheets and statements
of capitalization of Bay State Gas Company and subsidiaries as of September 30,
1995 and 1994, and the related consolidated statements of earnings,
shareholders' equity and cash flows for each of the years in the three-year
period ended September 30, 1995. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits 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 Bay State Gas Company and
subsidiaries at September 30, 1995 and 1994, and the results of their operations
and their cash flows for each of the years in the three-year period ended
September 30, 1995 in conformity with generally accepted accounting principles.
 
     As discussed in Notes 1, 2, and 7 to the consolidated financial statements,
the Company changed its methods of accounting for income taxes, postemployment
benefits and postretirement health and welfare benefits in 1994.

                     BAY STATE GAS COMPANY



                THREE-YEAR SEVERANCE AGREEMENT



THIS AGREEMENT, dated this      day of                 , 19  ,
made effective as of the date on which a Change in Control (as
defined in paragraph 2) occurs, by and between Bay State Gas
Company, a Massachusetts corporation, (herein referred to as the
"Company") and                                  having an
address at                                        (the
"Employee").



                 W I T N E S S E T H  T H A T:

WHEREAS, the Employee is an Employee of the Company and an
integral part of its management who participates in the
decision-making process relative to short- and long-term
planning and policy for the Company; and

WHEREAS, the Board of Directors of the Company, at its meeting
on January 26, 1989, determined that it would be in the best
interests of the Company, its shareholders and the Employee to
assure continuity in the management of the Company's
administration and operations in the event of a Change in
Control by entering into a severance Agreement to retain the
services of the Employee.

NOW, THEREFORE, it is hereby agreed by and between the parties
hereto as follows:

1.  Employment.  The Company agrees to continue the Employee in
its employ and the Employee agrees to remain in the employ of
the Company for the period stated in paragraph 4 hereof and upon
the other terms and conditions herein provided.

2.  Change in Control.  The term, "Change in Control:, shall
mean the occurrence of any of the following:

  (a)  the Company receives a report on Schedule 13D filed with
the Securities and Exchange Commission pursuant to Section 13(d)
of the Securities Exchange Act of 1934, as amended (hereinafter
referred to as the "Exchange Act"), disclosing that any person,
group, corporation or other entity is the beneficial owner,
directly or indirectly, of 25% or more of the outstanding common
stock of the Company;

  (b)  any person (as such term is defined in Section 13(d) of
the Exchange Act), group, corporation or other entity other than
the Company or a wholly-owned subsidiary of the Company,
purchases shares pursuant to a tender offer or exchange offer to
acquire any common stock of the Company (or securities
convertible into common stock) for cash, securities or any other
consideration, provided that after consummation of the offer,
the person, group, corporation or other entity in question is
the beneficial owner (as such term is defined in Rule 13d-3
under the Exchange Act), directly or indirectly, of 25% or more
of the outstanding common stock of the Company (calculated as
provided in paragraph (d) of Rule 13d-3 under the Exchange Act
in the case of rights to acquire common stock);

  (c)  the stockholders of the Company approve (i) any
consolidation or merger of the Company in which the Company is
not the continuing or surviving corporation or pursuant to which
shares of common stock of the Company would be converted into
cash, securities or other property, or (ii) any sale, lease,
exchange or other transfer (in one transaction or a series of
related transactions) of all or substantially all the assets of
the Company; or

<PAGE>   2

  (d)  there shall have been a change in a majority of the
members of the Board of Directors of the Company within a
25-month period unless the election or nomination for election
by the Company's stockholders of each new director was approved
by the vote of two-thirds of the directors then still in office
who were in office at the beginning of the 25-month period.

3.  Position and Responsibilities.  During the period of
employment hereunder, the Employee agrees to serve the Company
in an executive capacity.  Such service shall involve duties and
responsibilities at least equal in importance and scope to those
of the Employee's position immediately prior to the effective
date of this Agreement, as the Board of Directors, the Chairman
of the Board of Directors or Chief Executive Officer or any
other executive officer or any other executive officer of the
Company to whom the Employee reports may from time-to-time
determine.  During said period, the Employee also agrees to
serve, if elected, as an officer and/or director of any
subsidiary or affiliate of the Company.

4.  Term and Duties.

  (a)  The period of the Employee's employment under this
Agreement shall be deemed to have commenced as of the effective
date of this Agreement and shall continue for a period of 36
full calendar months thereafter.

  (b)  During the period of employment hereunder and except for
illness or incapacity and reasonable vacation periods, the
Employee's business time, attention, skill and efforts shall be
exclusively devoted to the business and affairs of the Company;
provided, however, that nothing in this Agreement shall preclude
the Employee from devoting time during reasonable periods
required for:

     (i)  serving as a director or member of a committee of any
company or organization involving no conflict of interest with
the Company or any of its subsidiaries or affiliates,

     (ii)  delivering lectures and fulfilling speaking
engagement, and

     (iii)  engaging in charitable and community activities,
provided that such activities do not materially affect or
interfere with the performance of the Employee's obligations to
the Company.

5.  Compensation.

  (a)  For all services rendered by the Employee in any capacity
during employment under this Agreement, including services as an
executive, officer, director or member of any committee of the
Company or of any subsidiary of affiliate of the Company, the
Company shall pay the Employee a fixed salary at an annual rate
not less than the annual rate of salary being paid to Employee
immediately prior to the effective date of this Agreement.  Such
salary shall be subject to such periodic percentage increases
after the effective date of this Agreement as the Company pays
generally to the Company's senior management employees from
time-to-time, and shall be payable in accordance with the
customary payroll practices of the Company.  Such periodic
increases in salary, once granted, shall not be subject to
revocation.

  (b)  In addition to the salary payable under subsection (a),
above, the Company shall also pay to the Employee annual bonuses
in an amount at least equal to the amount of the last payment to
the Employee under any short-term incentive performance program
of the Company or any subsidiary of the Company in effect during
the 12-month period prior to the effective date of this
Agreement.  Nothing in this subsection (b) shall be deemed to
require the Company to (i) have or continue an incentive
performance program in effect prior to the effective date of
this Agreement, or (ii) award to the Employee any bonuses under
such program prior to the effective date of this Agreement.

<PAGE>   3

  (c)  Nothing in this Agreement shall preclude or affect any
rights or benefits that may now or hereafter be provided for the
Employee or for which the Employee may be or become eligible
under any bonus or other form of compensation or employee
benefit plan now existing or that may hereafter be adopted or
awarded by the Company.  Specifically, the Employee shall:

     (i)  participate in the Bay State Gas Company Retirement
Plan and any related excess benefit or supplemental retirement
program (hereinafter referred to collectively as the "Retirement
Program");

     (ii)  participate in any savings or thrift plan maintained
by the Company;

     (iii) participate in any stock option, stock appreciation
right, equity incentive or deferred compensation plan maintained
by the Company;

     (iv)  participate in the Company's death benefit plans;

     (v)  participate in the Company's disability benefit plans;

     (vi)  participate in the Company's medical, dental and
health and welfare plans;

     (vii)  participate in equivalent successor plans of the
Company for which senior management employees are eligible; and

     (viii) be provided with such employee perquisites as may be
provided under Company policy to employees with a comparable
level of responsibility.

provided, however, that nothing in this Agreement shall preclude
the Company from amending or terminating any such plan or
program, on the condition that such amendment or termination is
applicable to all of the Company's senior management employees
generally.  For purposes of the foregoing, any plan or program
maintained by any subsidiary of the Company which is made
available to the senior management of the Company and its
subsidiaries taken as a whole, shall be deemed to be a plan or
program maintained by the Company.

6.  Business Expense.  The Company shall pay or reimburse the
Employee for all reasonable travel or other expenses incurred in
connection with the performance of the Employee's duties under
this Agreement in accordance with such procedures as the Company
may from time-to-time establish.

7.  Additional Benefits.  Nothing in this Agreement shall affect
the Employee's eligibility to participate in all group health,
dental, hospitalization, life, travel or accident or other
insurance plans or programs and all other perquisites (including
the use of a Company-owned car where applicable), fringe benefit
or retirement plans or additional compensation, including
termination pay programs, which the Company or any subsidiary of
the Company may hereafter, in their sole and absolute
discretion, elect to make available to the senior management
employees of the Company generally, and the Employee shall be
eligible to receive, during the period of employment under this
Agreement, all benefits and emoluments for which key employees
are eligible under every such plan, program, perquisite or
arrangement to the extent permissible under the general terms
and provisions thereof.

<PAGE>   4

8.  Termination of Employment.  Notwithstanding any other
provision of this Agreement, the Employee's employment under
this Agreement may be terminated:

  (a)  by the Company, in the event of the Employee's conviction
for the commission of a felony or in the event of Employee's
fraud or dishonesty which has resulted or is likely to result in
material economic damage to the Company or any of its
subsidiaries, as determined in good faith by the Directors of
the Company at a meeting of the Board of Directors at which the
Employee is provided and opportunity to be heard:

  (b)  by either the Company or the Employee, if the Employee
accepts employment or a consulting position with another company;

  (c)  by the Employee, if he determines in good faith that
there has been any (i) material change by the Company of the
Employee's functions, duties or responsibilities which change
would cause the Employee's position with the Company to become
of less dignity, responsibility, importance, prestige or scope
from that described in paragraph 3 above, including, without
limitation, a diminution in perquisites to which the Employee is
currently entitled, such as office size and status and
secretarial and clerical staff, (ii) assignment or reassignment
by the Company of the Employee to another place of employment
more than 50 miles from the Employee's current place of
employment, (iii) liquidation, dissolution, consolidation or
merger of the Company, or transfer of all or substantially all
of its assets, other than a transaction in which a successor
corporation or merger of the Company, or transfer of all or
substantially all of its assets, other than a transaction in
which a successor corporation with a net worth at least equal to
that of the Company immediately before such transaction assumes
this Agreement and all obligations and undertakings of the
Company hereunder, (iv) reduction in the Employee's total
compensation or any component thereof, as specified in paragraph
5 above, except as part of a salary reduction program affecting
the management employees of the Company and its subsidiaries
generally, or (v) notice to the Company, specifying the event
relied upon for such termination and given at any time within
one year after the occurrence of such event; or

  (d)  by the Company upon the Disability or death of the
Employee.  For purposes of this Agreement, the term "Disability"
is defined as the inability of the Employee to engage in his
regular occupation for 12 consecutive months and the inability
thereafter to engage in any occupation in which the Employee
could reasonably expect to engage giving due consideration to
Employee's education, training and experience.  The Employee
must be under the regular medical care of a physician in
connection with treatment for Disability.

9.  Payments Upon Termination of Employment.

  (a)  In the event of any termination of the Employee's
employment hereunder (i) by the Employee pursuant to paragraph
8(c), above, or (ii) by the Company for any reason other than
one of those specified in paragraph 8(a), 8(b) or 8(d), above,
then, except for Subsection (iv), below, within five business
days after any such termination the Company shall pay to the
Employee the following amounts, and shall provide the Employee
with the following, as liquidated damages or severance pay, or
both:

<PAGE>   5

    (i)  a lump sum cash amount equal to the present value of
the product obtained by multiplying (1) the monthly amount of
the salary and bonus provided for in paragraphs 5(a) and 5(b)
above, which was being paid by the Company to the Employee at
the time of such termination, by (2) 36;

    (ii)  a lump sum cash amount equal to the present value of
the excess of (1) the aggregate benefit that would have been
paid under the Retirement Program described in paragraph
5(c)(i), above, as in effect on the date of this Agreement, if
the Employee had continued to be employed and to be entitled to
service credit for eligibility and benefit purposes during the
36-month period immediately following such termination, over (2)
the aggregate benefit actually payable under the Retirement
Program and any successor retirement program of the Company. 
For purposes of such calculation, the following assumptions
shall apply:  (1) that the Employee would continue to be
compensated during the 36-month period following termination at
an annual rate of compensation equal to that used to calculate
the payments provided by paragraph 9(a) above, calculated on the
basis of the compensation amount used in the benefit formula
under the Retirement Program; (2) that the Employee is fully
vested in the benefit payable under the Retirement Program; and
(3) that the aggregate benefit that would have been paid under
the Retirement Program is as of either the normal or early
retirement date for which the Employee would have qualified, if
the Employee were still employed on that date, whichever would
produce the highest present value amount payable under this
paragraph;

    (iii)  a lump sum cash amount equal to the present value of
the contributions which would have been made by the Company or
any subsidiary of the Company to the Employee's account pursuant
to any savings or thrift plan maintained by the Company or any
subsidiary of the Company in which the Employee was
participating immediately prior to such termination, calculated
as if the Employee had continued to be employed and to be
entitled to such contributions during the 36-month period
immediately following such termination, at a rate of
contribution equal to that made by the Company or any subsidiary
of the Company during the most recent contribution period
preceding such termination; and

<PAGE>   6

    (iv)  a lump sum cash amount payable within five business
days after the end of the 36-month period and equal to (1) the
economic benefit that the Employee is eligible to receive on any
outstanding Company stock options, based on assumptions
determined by the Stock Option Committee upon advice of an
independent financial advisor and (2) the spread on any Company
stock option which would have been granted to the Employee
during the 36-month period immediately following such
termination.  For purposes hereof, the following assumptions
shall apply:  (1) that the Employee continued to be employed
during such 36-month period, and (2) that the Employee continued
receiving annual grants of options to purchase a number of
shares of the Company's common stock equal to the number of
shares which the Employee is entitled to purchase under the
option or options that the Employee received in the calendar
year in which the Employee last received options to purchase
Company common stock (assuming such options are exercisable in
full), and calculated on the assumption that such options were
granted to the Employee at the beginning of each calendar year
during such 36-month period at the same time and at the same
exercise price as the option to purchase Company common stock
which is first granted to any other senior executive of the
Company during each such year; provided, however, that if the
Employee was granted an option to purchase Company common stock
during the calendar year in which is employment terminates and
prior to such termination of employment, no additional payments
shall be made to him under this paragraph 9(a)(iv) with respect
to such calendar year; further provided, that for purposes of
this paragraph 9(a)(iv), the spread shall be calculated based on
the closing price of the Company's common stock on the last
business day of such 36-month period; and further provided, that
if such 36-month period does not begin with the month of January
or end with the month of December, the payment to the Employee
under this paragraph 9(d) with respect to the calendar years in
which such 36-month period begins and ends shall be multiplied
by a fraction, the numerator of which is the number of months of
the 36-month period in such year and the denominator of which is
12.  For purposes of this paragraph 9, the term "spread" means
the excess, if any, of the closing price on a national stock
exchange (or if the stock is no longer traded on a national
stock exchange, any regional or over-the-counter exchange on
which it is traded) of the Company's stock multiplied by the
number of the shares of Company common stock subject to a stock
option, over the option exercise price for such option.

Notwithstanding anything to the contrary in the paragraph
9(a)(iv), if as of the applicable calculation date, the
Company's common stock is no longer traded on any national,
regional or over-the-counter stock exchange, the fair market
value of the Company's common stock for purposes of determining
the amount of spread shall be the amount agreed to by the
Employee and the Company.  However, if the Employee and the
Company are not able to agree on a fair market value within 10
days after the date payment is due to be made to the Employee
under this paragraph 9(a)(iv), the fair market value of a share
of the Company's common stock shall be determined by a qualified
and independent appraiser selected by the Assistant Regional
Director of the American Arbitration Association or his
delegate.  Such appraiser shall deliver its final report to the
Company and the Employee immediately upon completion.  The
determination of the appraiser shall be final and binding an all
parties and shall include interest on such amount computed from
the date payment is due at such rate as determined by the
arbitrator.  Any payment to the Employee under paragraph
9(a)(iv), which was delayed pending such appraisal, shall be
made within five business days after the appraiser delivers its
report to the Company and the Employee.  All fees, costs and
expenses associated with such appraisal (including those of the
arbitrator) shall be paid by the Company.

<PAGE>   7

  (b)  For purposes of calculating the lump sum cash payments
provided by paragraph 9(a)(i) through (iv), above, present value
shall be determined by using a discount factor equal to one
percentage point below the Prime Rate, compounded annually.  The
"Prime Rate" shall be the base rate on corporate loans at large
U.S. money center commercial banks as reported in The Wall
Street Journal (or, if such rate is no longer published, such
other base rate on corporate loans by large money center
commercial banks in the United States to their most creditworthy
customers as published by any newspaper or periodical of general
circulation) as of the date on which termination shall have
occurred.

  (c)  For a period of 36 months (commencing with the month in
which termination shall have occurred), the Employee shall be
entitled to all Employee benefits provided for in paragraph
5(c)(iv) through (viii), above, as if the Employee were still
employed during such period under this Agreement, with benefits
based upon the compensation used to calculate the payments
provided by paragraph 9(a) above, and if and to the extent that
such benefits shall not be payable or provided under any such
plan, the Company shall pay or provide such benefits on an
individual basis.  The benefits provided for in paragraph
5(c)(viii), above, in accordance with this paragraph 9(c) shall
be secondary to any comparable benefits provided by another
employer.

  (d)  Notwithstanding the termination of the Employee, in the
event a Change in Control occurs prior to a vote of the
shareholders of the company on the approval of the Bay State Gas
Company 1989 Stock Option Plan, as approved by the Board of
Directors of the Company on January 26, 1989, then, within five
business days of such Change in Control, the Company shall pay
to the Employee a lump sum cash amount equal to the economic
benefit that the Employee would have been eligible to receive on
any Company stock options granted subject to shareholder
approval, had the shareholders approved such Plan, based on
assumptions determined by the Stock Option Committee upon the
advice of an independent financial advisor.

  (e) (i) In the event it shall be determined that any payment
or distribution by the Company to or for the benefit of the
Employee, whether paid or payable or distributed or
distributable pursuant to the terms of this Agreement or
otherwise (a "Payment"), would be subject to the excise tax
imposed by Section 4999 of the Internal Revenue Code of 1986, as
amended (the "Code") (or any successor thereto) or comparable
state or local tax or any interest or penalties with respect to
such excise tax or comparable state or local tax (such excise
tax, together with any such interest and penalties, are
hereinafter collectively referred to as the "Excise Tax"), then
the Employee shall be entitled to receive an additional payment
(a "Gross-Up Payment").  The Gross-Up Payment shall be equal to
the sum of the Excise Tax and all taxes (including any interest
or penalties imposed with respect to such taxes) imposed upon
the Gross-Up Payment.

<PAGE>   8

    (ii)  If the Employee determines that a Gross-Up Payment is
required, the Employee shall so notify the Company in writing,
specifying the amount of Gross-Up Payment required and details
as to the calculation thereof.  The Company shall within 30 days
either pay such Gross-Up Payment (net of applicable wage
withholding) to the Employee or furnish an unqualified opinion
from Independent Tax Counsel (as defined below), addressed to
the Employee and the Company, that there is substantial
authority (within the meaning of Section 6661 of the Code) for
the position that no Gross-Up Payment is required.  "Independent
Tax Counsel: mean a lawyer with expertise in the area of
executive compensation tax law, who shall be selected by the
Employee and shall be reasonably acceptable to the Company, and
whose fees and disbursements shall be paid by the Company.

  (iii)  If the Internal Revenue Service or other tax authority
proposes in writing an adjustment to the income tax of the
Employee which would result in a Gross-Up Payment, the Employee
shall promptly notify the Company in writing and shall refrain
for at least thirty days after giving such notice, if so
permitted by law, from paying any tax (including interest,
penalties and additions to tax) asserted to be payable as a
result of such proposed adjustment.  Before the expiration of
such period, the Company shall either pay the Gross-Up Payment
or provide an opinion from Independent Tax Counsel to the
Employee and the Company as to whether it is more likely than
not that the proposed adjustment would be successfully
challenged if the matter were to be litigated.  If the opinion
provides that a challenge would be more likely than not to be
successful if the issue were litigated, and the Company requests
in writing that the Employee contest such proposed adjustment,
then the Employee shall content the proposed adjustment and
shall consult in good faith with the Company with respect to the
nature of all action to be taken in furtherance of the contest
of such proposed adjustment; provided that the Employee, after
such consultation with the Company, shall determine in his sole
discretion the nature of all action to be taken to contest such
proposed adjustment, including (A) whether any such action shall
initially be by way of judicial or administrative proceedings,
or both, (B) whether any such proposed adjustment shall be
contested by resisting payment thereof or by paying the same and
seeking a refund thereof, and (C) if the Employee shall
undertake judicial action with respect to such proposed
adjustment, the court or other judicial action with respect to
such proposed adjustment, the court or other judicial body
before which such action shall be commenced and the court or
other judicial body to which any appeals should be taken.  The
Employee agrees to take appropriate appeals of any judicial
decision that would require the Company to pay a Gross-Up
Payment, provided the Company request in writing that the
Employee do so and provides an opinion from Independent Tax
Counsel to the Employee and the Company that it is more likely
than not to settle, compromise or otherwise terminate a contest
with the Internal Revenue Service or other tax authority with
respect to all or a portion of the proposed adjustment giving
rise to the Gross-Up Payment, if requested by the Company in
writing to do so at any time, in which case the Employee shall
be entitled to receive from the Company the Gross-Up Payment. 
In no event shall the Employee compromise or settle all or any
portion of a proposed adjustment which would result in a
Gross-Up Payment without the written consent of the Company.

<PAGE>   9

The Employee shall not be required to take or continue any
action pursuant to this paragraph 9(d) unless the Company
acknowledges its liability under this Agreement in the event
that the Internal Revenue Service or other tax authority
prevails in the contest.  The Company hereby agrees to indemnify
the Employee in a manner reasonably satisfactory to the Employee
for any fees, expenses, penalties, interest or additions to tax
which the Employee may incur as a result of contesting the
validity of any Excise Tax and to pay the Employee promptly upon
receipt of a written demand therefore all costs and expenses
which the Employee may incur in connection with contesting such
proposed adjustment (including reasonable fees and disbursements
of Independent Tax Counsel); provided, however, that the Company
shall not be required to pay any amount necessary to permit the
Employee's institution of a claim for refund under this
paragraph 9(d)(iii).

If the Employee shall have contested any proposed adjustment as
above provided, and for so long as the Employee shall be
required under the terms of this paragraph 9(d)(iii) to continue
such contest, the Company shall not be required to pay a
Gross-Up Payment until there occurs a Final Determination (ad
defined below) of the liability of the Employee for the tax and
any interest, penalties and additions to tax asserted to be
payable as a result of such proposed adjustment.  A "Final
Determination" shall mean (A) a decision, judgment, decree or
other order by any court of competent jurisdiction, which
decision, judgment, decree or other order has become final after
all allowable appeals by either party to the action have been
exhausted, the time for filing such appeal has expired or the
Employee has no right under the terms hereof to request an
appeal, (B) a closing agreement entered into under Section 7121
of the Code or any other settlement agreement entered into in
connection with an administrative or judicial proceeding and
with the consent of the Employee, or (C) the expiration of the
time for instituting a claim for refund, or if such a claim was
filed, the expiration of the time for instituting suit with
respect thereto.

  (iv)  In the event the Employee receives any refund from the
Internal Revenue Service or other tax authority on account of an
overpayment of Excise Tax, such amount, together with that part
of any Gross-Up Payment attributable to such amount, shall be
promptly paid by the Employee to the Company.

10.  Source of Payments.  All payments provided for in paragraph
5, 6, 7 and 9 shall be paid in cash from the general funds of
the Company and its subsidiaries.  The Company shall not be
required to establish or separate fund or other segregation of
assets to assure such payments.

<PAGE>   10

11.  Litigation Expenses.  In the event of any litigation or
other proceeding between the Company and the Employee with
respect to the subject matter of this Agreement and the
enforcement of rights hereunder, the Company shall reimburse the
Employee for all reasonable costs and expenses relating to such
litigation or other proceeding as they are incurred, including
reasonable attorneys' fees and expenses, regardless of whether
such litigation results in any settlement or judgment or order
in favor of any party; provided, however, that any claim or
action initiated by the Employee relating to this Agreement
shall have been made or brought after reasonable inquiry and
shall be well-grounded, in fact, and warranted by existing law
or a good faith argument for the extension, modification or
reversal of existing law, and that is not interposed for any
improper purpose, such as to harass or to cause unnecessary
delay or needless increase in the cost of litigation.

Notwithstanding any provision of Massachusetts law to the
contrary, in no event shall the Employee be required to
reimburse the Company for any of the costs and expenses relating
to such litigation or other proceeding.  The obligation of the
Company under this paragraph 11 shall survive the termination
for any reason of this Agreement (whether such termination is by
the Company, by the Employee, upon the expiration of this
Agreement or otherwise).

12.  Income Tax Withholding.  The Company may withhold from any
payments made under this Agreement all federal, state, city or
other taxes as shall be required pursuant to any law or
governmental regulation or ruling.

13.  Entire Understanding.  This Agreement contains the entire
understanding between the Company and the Employee with respect
to the subject matter hereof and supersedes any prior employment
agreement between the Company and the Employee.

14.  Severability.  If, for any reason, any one or more of the
provisions or part of a provision contained in this Agreement
shall be held to be invalid, illegal or unenforceable in any
respect, such invalidity, illegality or unenforceability shall
not affect any other provision or part of a provision of this
Agreement not held so invalid, illegal or unenforceable, and
each other provision or part of a provision shall to the full
extent consistent with law continue in full force and effect.

15.  Consolidation, Merger or Sales of Assets.  Nothing in this
Agreement shall preclude the Company from consolidating or
merging into or with, or transferring all of substantially all
of its assets to, another corporation with a net worth at least
equal to that of the Company and which assumes this Agreement
and all obligations and undertakings of the Company hereunder. 
Upon such a consolidation, merger or transfer of assets and
assumption, the term "the Company", as used herein shall mean
such other corporation and this Agreement shall continue in full
force and effect.

discretion, in special cases, including, but not limited to,
Participant illness or extraordinary service, modify or waive
ancillary Plan provisions to meet the needs of the situation. 
However, no termination, amendment, suspension or modification
of the Plan will affect a retired Participant's right to
continue to receive a benefit in accordance with the Plan as in
effect on the date such Participant commenced to receive a
benefit hereunder, nor will any such termination, amendment,
suspension or modification result in a reduction of a
Participant's accrued benefit based on the Participant's
earnings and Service to the date of such change in the Plan.

conferring on any person any right of any nature, other than the

payments of benefits under the Plan solely on a current basis

                                                               EXHIBIT 10.08



                            BAY STATE GAS COMPANY

                    KEY EMPLOYEE LONG-TERM INCENTIVE PLAN





         1.     Purposes of Plan

        The purposes of the Bay State Gas Company Key Employee
Long-Term Incentive Plan (the "Plan") are to provide long-term
incentives for and to increase the opportunity for ownership in
Bay State Gas Company (the "Company") by those employees who are
directly responsible for the management, growth and success of
the Company's business.  



         2.     Administration of Plan

        The plan shall be administered by the Compensation Committee
(the "Committee") appointed by the Board of Directors of the
Company, which shall consist of two or more members of the Board
who qualify as disinterested persons, within the meaning of Rule
16b-3 promulgated under the Securities Exchange Act of 1934, as
amended (the "Exchange Act") and as outside directors, within
the meaning of Section 162(m) of the Internal Revenue Code of
1986, as amended (the "Code").  No member of the Committee shall
be eligible to receive an award under the Plan.  



        The Committee shall act by a majority of its members, without
the necessity of a meeting.  The Committee shall have full
power, discretion and authority to interpret and administer the
Plan, and any interpretation or other determination made, and
any action taken, by the Committee shall be conclusive and
binding on all persons having an interest under the Plan, except
as otherwise determined by the Board of Directors.  



         3.     Participation

        Each executive or management employee of the Company or an
affiliated company of Grade 35 or above and any other employee
designated by the Board of Directors of the Company who holds a
position which, by virtue of its scope, may have a material
effect on the performance of the Company or who is a significant
contributor to a specific project which is anticipated to have a
material effect on the Company's performance shall be eligible
to participate in the Plan.  



         4.     Performance Shares

        The maximum number of performance shares ("Performance Shares")
which may be awarded under the Plan is 500,000.  Each
Performance Share shall, upon vesting in accordance with the
provisions of the Plan, be exchangeable for one share of the
Company's common stock, par value $3.33 1/3 per share ("Common
Stock") and a cash payment equal to the dividends paid on a
share of Common Stock during the performance period, as defined
below.  The award of Performance Shares shall not entitle a
participant to any rights as a shareholder of the Company.  Any
Performance Shares awarded under the Plan which are forfeited or
canceled may again be awarded under the Plan.  


<PAGE>   2

         5.     Grant of Awards

        The Committee may grant awards of Performance Shares to
eligible employees, who shall then become participants in the
Plan, as of October 1 of each year from 1994 through 2003,
inclusive.  The Committee shall recommend and the Board of
Directors approve the eligible employees to whom awards are to
be granted and the amount of the award for each employee, except
that Performance Shares awarded to any one employee shall not
exceed 100,000 in the aggregate or the period the Plan is in
effect.  


         6.     Vesting

        A participant shall become entitled to payment of all or a
portion of the Performance Shares awarded to him or her in any
year at the end of the three-consecutive year period beginning
on the date the award is granted (a "Performance Period"), as
determined in accordance with Schedule A, depending on the
Compay's total return to shareholders for the Performance
Period.  


        Except as otherwise provided in Section 7, if a participant
terminates employment with the Company and its affiliates,
voluntarily or involuntarily, he or she shall forfeit all
Performance Shares awarded for the Performance Period in which
the termination of employment occurs.  


         7.     Retirement, Disability or Death of Participant

        In the event a participant terminates employment by reason of
retirement, disability or death, the participant shall be
entitled to payment of a portion of the Performance Shares
awarded to him or her for the Performance Period in which the
termination occurs.  Such portion shall be equal to the award
determined under Section 6, based on the Company's total return
to shareholders for the Performance Period to the date of the
participant's termination of employment, multiplied by a
fraction equal to the portion of the Performance Period for
which the employee was employed by the Company or an affiliate.  


        A participant may designate a beneficiary, or revoke a
beneficiary designation, under the Plan at any time.  However,
no designation or revocation shall be effective prior to its
receipt by the Committee.  


        For purposes of the Plan, disability means the complete and
permanent inability of an employee to perform his or her duties
under the terms of his or her employment.  The determination of
disability shall be made by the Committee, in its sole
discretion, on the basis of evidence, including medical
examination and reports, satisfactory to the Committee.  


         8.     Change of Control

        In the event of a change of control of the Company, as defined
in this Section 8, each Participant shall be entitled to payment
of 50 percent of the Performance Shares awarded to him or her
for the Performance Period in which the change of control
occurs.  A change of control shall be considered to have
occurred if:

<PAGE>   3


        (a)     any person, entity or group of persons (other than the
Company or any wholly-owned subsidiary of the Company), within
the meaning of sections 13(d) or 14(d) of the Exchange Act,
becomes the beneficial owner, within the meaning of Rule 13d-3
promulgated under such Act, directly or indirectly, of 25
percent of more of the Company's then outstanding shares of
commone stock, par value $3.33 1/3 per share ("Common Stock"); 


        (b)     any person, entity or group of persons (other than the
Company or any wholly-owned subsidiary of the Company), after
purchasing Common Stock of the Company in a tender or exchange
offer, becomes the beneficial owner, directly or indirectly, of
25 percent or more of the Common Stock; 


        (c)     the shareholders of the Company approve (i) a merger or
consolidation of the Company in which the Company is not the
continuing or surviving corporation or pursuant to which the
shares of Common Stock would be converted into cash, securities
or other property, or (ii) any sale, lease, exchange or other
transfer of all or substantially all of the Company's assets; or


        (d)     there is a change in the majority of the members of the
Company's Board of Directors within a 25-month period, unless
such change has been approved by two-thirds of the Directors
then still in office who were in office at the beginning of the
25-month period.  


         9.     Payment of Awards

        Payment of Performance Shares shall be made by the issuance of
the Company of an equal number of shares of Common Stock. 
Shares shall be issued to the participant, or, in the event of
the participant's death, his or her beneficiary.  Such shares
shall be made available from authorized and unissued shares or
treasury shares.  


        The participant (or beneficiary) shall also receive payment in
cash of an amount equal to the dividends paid during the
Performance Period on an equal number of shares of Common Stock.


        Payment of Performance Shares and cash shall be made as soon as
practicable after the event giving rise to the participant's
entitlement to payment.  


        10.     Nontransferability of Awards

        Neither Performance Shares nor any interest of a participant
under the Plan shall be sold, transferred, pledged, assigned,
disposed of or encumbered, voluntarily or by operation of law.  


        11.     Compliance with Securities Laws

        If at any time the Company determines that the listing,
registration or qualification of Performance Shares or shares of
Common Stock issuable pursuant to an award of Performance Shares
on any securities exchange or under any federal or state law, or
the approval of any governmental entity, is necessary to the
issue or transfer of such shares, such Performance

<PAGE>   4

shares or shares of Common Stock may not be accepted unless the
listing, registration, qualification or approval is obtained. 
However, the Company shall not be required to apply for or to
obtain such listing, registration, qualification or approval.  


        12.     Forfeiture and Cancellation of Shares

        Performance Shares awarded to a participant to which he or she
does not become entitled shall be forfeited and cancelled.  The
Committee may also cancel Performance Shares with the written
consent of the participant to whom the Shares were awarded.  In
the event of any cancellation, all rights of the participant
with respect to the cancelled Performance Shares shall
terminate, and the Shares shall be available for subsequent
award under the Plan.  


        13.     Adjustments

        In the event of any recapitalization, reclassification, stock
dividend, stock split, change in par value, merger,
consolidation or similar event involving a change in the capital
structure of the Company, the Committee may make such
adjustments in Performance Shares or awards and shares of Common
Stock available for issuance under the Plan, or the terms,
conditions or restrictions on such Performance Shares or awards,
as the Committee considers equitable.  


        14.     Withholding

        A participant or beneficiary receiving an award shall pay to
the Company the amount of any taxes required to be withheld with
respect to Common Stock issued to him or her under the Plan. 
The Company may deduct from awards any taxes required to be
withheld on the cash portion of such award.  


        15.     Amendment and Termination

        The Company at any time may amend or terminate the Plan by
action of the Board of Directors.  No amendment shall, without
the approval of the shareholders of the Company, cause the Plan
no longer to comply with Rule 16b-3 under the Exchange Act or
any listing requirement or no longer to be described in Section
162(m) (4) (C) of the Code.  The termination or amendment of the
Plan shall not adversely affect any right or obligation with
respect to any award previously granted to a participant.  


        16.     No Employment or Other Rights

        No employee shall have any claim or right to the grant of an
award under the Plan.  Neither the Plan nor any action taken by
the Company or the Committee under the Plan shall be construed
as giving any employee any right to be retained in the employ of
the Company or any affiliated company.  


        17.     Shareholder Approval

        The Plan shall be subject to the approval of the shareholders
of the Company.  In the event such approval is not obtained, all
awards under the Plan shall be null and void and the Plan shall
be of no force and effect.  


<PAGE>   5

        18.     Effective Date and Duration of Plan

        Subject to Section 17, the Plan shall become effective as of
July 28, 1994.  The Plan shall remain in effect for a period of
ten years commencing on such date, except that any awards
outstanding at the end of such period shall remain subject to
the terms, conditions and restrictions of the document
evidencing the award and the Plan as in effect at the date of
grant of the award.  



        19.     Governing Law

        The Plan shall be governed by the laws of the Commonwealth of
Massachusetts.
