Item 1: Business.

General

  Essex Gas Company ("The Company") is a regulated public utility organized
under the laws of the Commonwealth of Massachusetts in 1853 that is engaged in
the transportation and sale of natural gas to approximately 43,000
residential, commercial and industrial customers in northeastern
Massachusetts. The Company operates in the cities of Haverhill, Newburyport,
and Amesbury and fourteen smaller municipalities covering an area of
approximately 280 square miles. The Company's service area is primarily
comprised of residential communities with a number of small commercial and
diverse industrial businesses.

  As discussed in Note 1 of the Notes to Consolidated Financial Statements,
pursuant to an Agreement and Plan of Merger dated as of December 19, 1997, by
and between the Company and Eastern Enterprises ("Eastern"), ECGC Acquisition
Gas Company, a wholly-owned subsidiary of Eastern, merged with and into the
Company on September 30, 1998, through an exchange of all of the Company's
stock for approximately 2,047,000 shares of Eastern common stock, with the
Company surviving the merger as a wholly-owned subsidiary of Eastern (the
"Acquisition"). On November 6, 1998, the Company changed its name from Essex
County Gas Company to Essex Gas Company. On December 7, 1998, the Company
changed its fiscal year end from August 31 to December 31, and accordingly has
prepared Consolidated Financial Statements for the period beginning September
1, 1998 and ending December 31, 1998 ("Transition Period").

  On November 4, 1999, Eastern signed a definitive agreement to be acquired by
KeySpan Corporation. Subject to receipt of satisfactory regulatory approvals
and the approval of Eastern shareholders, the transaction is expected to close
in mid to late 2000, although it is possible that the transaction will not
close until 2001.

  For definitions of certain industry specific terms, see the Glossary at the
end of Part I and appearing on page 6.

  The Company provides local transportation services and gas supply to all
customer classes. The Company's services are available on a firm and non-firm
basis. Firm transportation service and sales are provided under rate tariffs
and/or contracts filed with the Massachusetts Department of Telecommunications
and Energy ("Department"), that typically obligate the Company to provide
service without interruption throughout the year. Non-firm transportation
service and sales are generally provided to large commercial/industrial
customers who can use gas or another energy source interchangeably. Non-firm
services are provided through individually negotiated contracts and, in most
cases, the price charged takes into account the price of the customer's
alternative fuel.

  The Company offers unbundled services to all commercial/industrial users,
who are allowed to purchase local transportation from the Company separately
from the purchase of gas supply, which the customer may buy from third party
suppliers. The Company views these third party suppliers as partners in
marketing gas and increasing throughput and expects to work closely with them
to facilitate the unbundling process and ensure a smooth transition,
especially in the tracking and processing of transactions. The Company has
also implemented a program to educate commercial/industrial customers about
the opportunity to purchase gas from third-party suppliers, while still
relying on the utility for delivery. As of December 31, 1999, the Company had
approximately 98 firm transportation customers. Service to all residential
customers currently is on a bundled basis. Unbundled service to residential
customers is expected to be offered beginning in June 2000. While the
migration of customers to transportation-only service will lower the Company's
revenues, it has no impact on its operating earnings. The Company earns all of
its margins on the local distribution of gas and none on the resale of the
commodity itself.
<PAGE>

Competition

  The Company competes with other fuel distributors, primarily oil dealers and
electricity providers, throughout its service territory. The Company currently
serves approximately 53% of the potential customers within its service
territory.

Gas Throughput

  The following table provides information with respect to the volumes of gas
sold and transported by the Company in thousands of dekatherms ("Dth") during
the year ended December 31, 1999, the four months ended December 31, 1998 (the
"Transition Period") and the two fiscal years ended August 31, 1998.

</TABLE>

  The above table excludes the effect of adopting the accrual method of
revenue recognition as discussed in Note 1 of Notes to Consolidated Financial
Statements.

  In 1999, residential customers comprised 90% of the customer base, while
commercial and industrial establishments accounted for the remaining 10%.
Volumetrically, residential customers accounted for 61% of total throughput
and 65% of total firm throughput, while commercial and industrial customers
accounted for 39% of total throughput and 35% of total firm throughput.

  No customer, or group of customers under common control, accounted for 2% or
more of total firm revenues in 1999.

Gas Supply

  The Company's supply requirements are purchased directly from producers and
marketers pursuant to contracts that have been approved by the Department or
by the Federal Energy Regulatory Commission ("FERC").

  Pipeline supplies are transported on interstate pipeline systems to the
Company's service territory pursuant to long-term contracts. FERC-approved
tariffs provide for fixed demand charges for the firm capacity rights under
these contracts. The interstate pipeline company that provides firm
transportation service to the Company's service territory, the peak daily and
annual capacity and the contract expiration dates are as follows:

     Tennessee Gas Pipeline Company......... 28,590 10,435,350    2003-2011
</TABLE>

  In 1999, the Company restructured its long-term capacity contracts with
Tennessee Gas Pipeline. As a result, no contracts expire before 2003.

  The Company also has two contracts with pipeline companies for the storage
of natural gas in underground storage fields in New York and Pennsylvania.
These contracts provide storage capacity of approximately 1.2 BCF and
approximately .009 BCF of peak day deliverability.

  In the fall of 1999, the Company, and its affiliates Boston Gas Company and
Colonial Gas Company, entered into a portfolio management contract with El
Paso Energy Marketing, Inc. For a three year term commencing November 1, 1999,
El Paso will provide all of the city gate supply requirements to the three
companies at market prices and manage certain of the companies' upstream
capacity, underground storage and term supply contracts. The Department
approved the contract in October 1999.

  Peak day firm throughput in BCF was 0.049 in 1999, 0.043 in 1998 and 0.047
in 1997. The Company has entered into an agreement with Distrigas of
Massachusetts Corporation which expires on October 31, 2006, that allows the
Company to purchase up to 4,000 Dth per day for 151 days of liquefied natural
gas ("LNG") in either liquid or vapor form. The Company, at its discretion,
may increase purchases under the contract by up to 2,000 Dth per day after
appropriate notice. The Company may also reduce quantities purchased if sales
fall below the normal 1994-95 heating season sendout.

  Through a wholly-owned subsidiary, the Company owns a LNG storage facility
located in Haverhill, Massachusetts. The LNG storage facility has storage
capacity of 410,000 Dth and daily sendout capacity of 30,000 Dth. At the same
location, the Company owns and operates a propane plant that has storage
capacity of approximately 42,000 Dth with total daily sendout capacity of
3,500 Dth. The Company considers its peak day sendout capacity, based on its
total supply resources, to be adequate to meet the requirements of its firm
customers.

Regulation

  The Company's operations are subject to Massachusetts statutes applicable to
gas utilities. Rates for transportation service, gas purchases and sales,
pipeline safety regulations, issuance of securities, and affiliate
transactions are regulated by the Department. Rates for firm transportation
and sales are subject to approval by, and are on file with, the Department. In
addition, the Company has a cost of gas adjustment clause ("CGAC") that allows
for the adjustment of billing rates for firm gas sales to enable it to recover
the actual cost of gas delivered to firm customers, including the demand
charges for capacity on the interstate pipeline system. Similarly, through its
local distribution adjustment clause ("LDAC"), the Company recovers the costs
of remediating former manufactured gas plant sites from all firm customers,
including those purchasing gas supply from third parties.

                                       3
<PAGE>

  On September 30, 1998, the Company was acquired by Eastern, the Weston,
Massachusetts based owner of Boston Gas Company ("Boston Gas"). On September
17, 1998, the Department approved the merger and rate plan. Under the approved
rate plan, there was an immediate five percent price reduction for the
Company's customers and a ten year freeze of base rates. The freeze on base
rates is subject only to certain exogenous factors, such as changes in tax
laws, accounting changes, or regulatory, judicial, or legislative changes. As
a result of the rate plan, the Company discontinued its application of SFAS
No. 71, as described in Note 1 of Notes to Consolidated Financial Statements.
Gas supply savings resulted from the consolidation of the Company's resource
portfolio with the Boston Gas portfolio. Many of the administrative,
operations and maintenance functions of the Company have been integrated with
those of Boston Gas.

  All of the Company's 4,300 commercial and industrial customers are eligible
to purchase unbundled local transportation service from the Company and to
purchase their gas supply from third parties. As of December 31, 1999, the
Company had 98 firm transportation customers.

  Anticipating a date of June 1, 2000 for offering residential customers the
opportunity to purchase gas supply from third parties, the Department has
approved Model Terms and Conditions to which LDC tariffs for all residential
customers will substantially conform. The Model Terms and Conditions approved
by the Department are consistent with the Department's order of February 1,
1999, which provided that, for a five year transition period, LDC contractual
commitments to upstream capacity will be assigned on a mandatory, pro rata
basis to marketers selling gas supply to the LDC's customers. The approved
mandatory assignment method eliminates the possibility that the costs of
upstream capacity purchased by the Company to serve firm customers will be
absorbed by the LDC or other customers through the transition period. The
Department also found that, through the transition period, LDC's will retain
primary responsibility for upstream capacity planning and procurement to
assure that adequate capacity is available at Massachusetts city gates to
support customer requirements and growth. In year three of the five year
transition period, the Department intends to evaluate the extent to which the
upstream capacity market for Massachusetts is workably competitive based on a
number of factors, and accelerate or decelerate the transition period
accordingly. The Department's Model Terms and Conditions also require that
LDC's provide default and peaking supply services at cost-based rates.

Seasonality and Working Capital

  The Company's revenues, earnings and cash flows are highly seasonal as most
of its transportation services and sales are directly related to temperature
conditions. Because the majority of its revenues are billed in the November
through April heating season, significant cash flows are generated from late
winter to early summer. In addition, through the cost of gas adjustment
clause, the Company bills its customers over the heating season for the
majority of the pipeline demand charges paid by the Company over the entire
year. This difference, along with other costs of gas distributed but unbilled,
is reflected as deferred gas costs and is financed through short-term
borrowings. Short-term borrowings are also required from time to time to
finance normal business operations. As a result of these factors, short-term
borrowings are generally highest during the late fall and early winter.

Environmental Matters

  The Company may have or share responsibility under applicable environmental
law for the remediation of four former manufactured gas plants ("MGP"), one
former gas holder site associated with MGP operations and one non-MGP site,
and may share responsibility with respect to two federal superfund sites.
Information with respect to these matters may be found at Note 10 of Notes to
Consolidated Financial Statements. Such information is incorporated herein by
reference.

Employees

  As of December 31, 1999, the Company had 62 employees, 84% of whom are
organized in a local union with which the Company has a collective bargaining
agreement that expires in 2002. During 1999, the Company entered into a new
three-year agreement with the bargaining unit representing union employees.

Item 2: Properties.

  The Company's property consists primarily of its distribution system and
related facilities. The Company also owns a propane plant with a storage
capacity of 42,000 Dth. In addition, the Company, through its wholly-owned
subsidiary, LNG Storage, Inc., owns a LNG storage facility with a storage
capacity of 410,000 Dth.

  Substantially all of the properties owned by the Company, other than
expressly exempted property, are subject to a lien under the indenture
securing the Company's First Mortgage Bonds. The indenture calls for a trustee
or receiver to take possession of the property if there is a default under its
terms. The property exempted from the lien includes cash, receivables,
supplemental fuel inventories, materials and supplies, rental appliances,
office furniture and equipment, and the LNG storage facility.

  The Company leases a 30,000 square foot building which expires in October,
2005.

  On December 31, 1999, the Company's distribution system included
approximately 800 miles of gas mains, 37,000 services and 44,000 active
customer meters.

  The Company's gas mains and services are usually located on public ways or
private property not owned by it. In general, the Company's occupation of such
property is pursuant to easements, licenses, permits or grants of location.
Except as stated above, the principal items of property of the Company are
owned in fee.

  In 1999, the Company's capital expenditures were $5.1 million. Capital
expenditures were principally made for improvements to the distribution system
and for system expansion to meet customer growth. The Company plans to spend
approximately $8 million for similar purposes in 2000.

Item 3: Legal Proceedings.

  Other than certain routine claims incidental to its business, there are no
material pending legal proceedings involving the Company.

Item 4: Submission of Matters to a Vote of Security Holders.

  No matter was submitted to a vote of Security Holders in the fourth quarter
of 1999.

Item 5: Market for Registrant's Common Equity and Related Stockholder Matters.

  Eastern has been the holder of record of all the outstanding common equity
securities of the Company since September 30, 1998. Dividends paid to Eastern
amounted to $5.6 million in 1999.

Item 6: Selected Financial Data.

  Not required.

Item 7: Management's Discussion and Analysis of Financial Condition and
Results of Operations.

RESULTS OF OPERATIONS

 1999 Compared to 1998

  Net earnings for the year ended December 31, 1999 were $5.9 million compared
to $4.3 million for the fiscal year ended August 31, 1998. The improvement in
earnings was principally due to lower operations and maintenance expenses,
merger related synergies resulting from reduced employee levels and associated
benefits, partially offset by a $1.3 million early retirement and severance
charge.

 The four months ended December 31, 1998 Compared to the four months ended
December 31, 1997

  Results for the four month period ended December 31, 1998 and 1997 are not
comparable due to the effect of merger related expenses, the impact of
discontinuing the application of Statement of Financial Accounting Standards
No. 71 "Accounting for the Effects of Certain Types of Regulation" ("SFAS No.
71") and the impact of 23% warmer weather than the prior year. Merger related
expenses for professional fees, termination benefits, and other related costs
were $7.9 million on a pre-tax basis. As a result of the rate plan and
extended base rate freeze, the Company was required to discontinue the
application of SFAS No. 71 and adopt the accrual method of accounting for
revenues. These changes resulted in an extraordinary charge of approximately
$2.9 million, net, principally due to the write off of regulatory assets
associated with postretirement benefits. The impact of significantly warmer
weather was offset by the adoption of the accrual method of accounting for
revenue.

 August 31, 1998 Compared to August 31, 1997

  Net earnings applicable to common stock for 1998 were $4.3 million, an
increase of $.3 million or 8% as compared to 1997. The increase primarily
reflects customer growth, the annualized effect of a base rate increase
granted by the Department effective December 1, 1996 and lower operations and
maintenance expense. The improvement in earnings was partially offset by
warmer weather and a higher charge for depreciation reflecting continued
investment in system replacement and expansion. Weather for 1998 was 11%
warmer than normal and 9% warmer than 1997.

YEAR 2000 ISSUE

  The Company experienced no significant issues as a result of the transition
from December 31, 1999 to January 1, 2000. The Company does not expect to
incur any significant Year 2000 related costs beyond January 2000. On
September 30, 1998, the Company was merged with Eastern, the parent company of
Boston Gas Company. In connection with the merger, the Company addressed any
remaining Year 2000 issues through conversion to systems operated by Boston
Gas Company.


FORWARD-LOOKING INFORMATION

  This report and other Company reports and statements issued or made from
time to time contain certain "forward-looking statements" concerning projected
future financial performance, expected plans or future operations. The Company
cautions that actual results and developments may differ materially from such
projections or expectations.

                                       7
<PAGE>

  Investors should be aware of important factors that could cause actual
results to differ materially from forward-looking projections or expectations.
These factors include, but are not limited to: the effect of strategic
initiatives on earnings and cash flow, the impact of any merger-related
activities, the ability to successfully integrate natural gas distribution
operations, temperatures above or below normal, changes in economic
conditions, including interest rates, regulatory and court decisions and
developments with respect to previously-disclosed environmental liabilities.
Most of these factors are difficult to predict accurately and are generally
beyond the control of the Company.

LIQUIDITY AND CAPITAL RESOURCES

  The Company has a $10 million line of credit for the exclusive purpose of
funding its fuel inventory.

  The Company expects capital expenditures for 2000 to be $8 million. Capital
expenditures will be primarily for improvements to the distribution system and
for system expansion to meet customer growth.

  The Company believes that projected cash flow from operations, in
combination with currently available resources, is more than sufficient to
meet 2000 capital expenditures, working capital requirements, dividend
payments and normal debt repayments.

OTHER MATTERS

 Regulatory and Accounting Issues

  The Company's operations are subject to Massachusetts statutes applicable to
gas utilities. Rates, gas purchases, pipeline safety regulations, issuance of
securities, and affiliate transactions are regulated by the Department. Rates
for firm transportation and sales are subject to approval by, and are on file
with, the Department. In addition, the Company has a cost of gas adjustment
clause ("CGAC") that allows for the adjustment of billing rates for firm gas
sales to enable it to recover the actual cost of gas delivered to firm
customers, including the demand charges for capacity on the interstate
pipeline system. Similarly, through its local distribution adjustment clause
("LDAC"), the Company recovers the actual costs of remediating former
manufactured gas plant sites from all firm customers, including those
purchasing gas supply from third parties.

  On September 30, 1998, the Company was acquired by Eastern, the Weston,
Massachusetts based owner of Boston Gas Company ("Boston Gas"). On September
17, 1998, the Department approved the merger and rate plan. Under the approved
rate plan, there was an immediate five percent price reduction for the
Company's customers and a ten year freeze of base rates. The freeze on base
rates is subject only to certain exogenous factors, such as changes in tax
laws, accounting changes, or regulatory, judicial, or legislative changes. Gas
supply savings resulted from the consolidation of the Essex Gas resource
portfolio with the Boston Gas portfolio. As a result of the rate plan, the
Company discontinued its application of SFAS No. 71, as described in Note 1 of
Notes to Consolidated Financial Statements. Many of the administrative,
operations and maintenance functions of the Company have been integrated with
those of Boston Gas.

  All of the Company's 4,300 commercial and industrial customers are eligible
to purchase unbundled local transportation service from the Company and to
purchase their gas supply from third parties. As of December 31, 1999, the
Company had 98 firm transportation customers.

  Anticipating a date of June 1, 2000 for offering residential customers the
opportunity to purchase gas supply from third parties, the Department has
approved Model Terms and Conditions to which LDC tariffs for all residential
customers will substantially conform. The Model Terms and Conditions approved
by the Department are consistent with the Department's order of February 1,
1999, which provided that, for a five year transition period, LDC contractual
commitments to upstream capacity will be assigned on a mandatory, pro rata
basis to marketers selling gas supply to the LDC's customers. The approved
mandatory assignment method eliminates the possibility that the costs of
upstream capacity purchased by the Company to serve firm customers

                                       8
<PAGE>

will be absorbed by the LDC or other customers through the transition period.
The Department also found that, through the transition period, LDC's will
retain primary responsibility for upstream capacity planning and procurement
to assure that adequate capacity is available at Massachusetts city gates to
support customer requirements and growth. In year three of the five year
transition period, the Department intends to evaluate the extent to which the
upstream capacity market for Massachusetts is workably competitive based on a
number of factors, and accelerate or decelerate the transition period
accordingly. The Department's Model Terms and Conditions also require that
LDC's provide default and peaking supply services at cost-based rates.

 Environmental Matters

  The Company may have or share responsibility under applicable environmental
law for the remediation of four former manufactured gas plants ("MGP"), one
former gas holder site associated with MGP operations, and one non-MGP site,
and may share responsibility with respect to two federal superfund sites.
Information with respect to these matters may be found at Note 10 of Notes to
Consolidated Financial Statements. Such information is incorporated herein by
reference.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1) Summary of Significant Accounting Policies

 General

  Essex Gas Company (the "Company") is a public utility engaged in the
distribution and sale of natural gas for residential, commercial and
industrial uses. Its service area is northeastern Massachusetts.

 Principles of Consolidation

  The consolidated financial statements include the accounts of LNG Storage,
Inc., a wholly-owned subsidiary. All material intercompany balances and
transactions have been eliminated.

  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

 Merger

  On September 30, 1998, the Company merged with ECGC Acquisition Company, a
wholly-owned subsidiary of Eastern Enterprises ("Eastern"), through the
exchange of all the Company's stock for approximately 2,047,000 shares of
Eastern common stock. The merger was accounted for as a pooling of interests
by Eastern.

  On December 7, 1998, the Company changed its fiscal year end from August 31
to December 31 to conform to Eastern's fiscal year end. The transition period
("Transition Period") ended December 31, 1998 reflects the results of
operations and cash flows for the four months then ended and precedes the
start of the new fiscal year. Unaudited financial results of operations for
the four months ended December 31, 1997 are reflected on a comparative basis
in Note 11 of the Notes to Consolidated Financial Statements.

  The merger related transaction fees, termination benefits and related
expenses charged against pre-tax earnings during the Transition Period totaled
$7,904,000.

  In connection with the merger, the Massachusetts Department of
Telecommunications and Energy ("the Department") approved a rate plan that
resulted in an immediate five percent price reduction through the cost of gas
adjustment clause ("CGAC") and a ten year freeze of base rates at current
levels. Given the length of the base rate freeze, the Company was required to
discontinue its application of Statement of Financial Accounting Standards
(SFAS) No. 71 "Accounting for the Effects of Certain Types of Regulation"
during the Transition Period. Accordingly, the Company wrote off net
regulatory assets of $4,835,000, consisting principally of postretirement
costs. In addition, the Company was required to adopt certain accounting
practices in order to comply with generally accepted accounting principles for
nonregulated entities and to maintain consistency with its new parent. As
such, the Company recorded a nonrecurring pre-tax gain of $335,000 due to the
adoption of a revenue method that reflects full accrual accounting, as
discussed below. Adjustments to reflect this new practice and the
discontinuance of SFAS No. 71 are included in the extraordinary item, net of
tax in the Consolidated Statements of Earnings.

 Regulation

  The Company's operations are subject to Massachusetts statutes applicable to
gas utilities.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

(1) Summary of Significant Accounting Policies (continued)

  For the periods prior to the approval of the merger and rate plan, the
accounting policies conformed to generally accepted accounting principles as
applied to regulated public utilities and reflected the effects of the
ratemaking process in accordance with SFAS No. 71. Under SFAS No. 71, the
Company was allowed to defer certain costs that otherwise would be expensed in
recognition of the ability to recover them in future rates. As described
above, the Company discontinued application of SFAS No. 71 as a result of the
rate plan approved by the Department in connection with its approval of the
merger of the Company with Eastern.

 Gas Operating Revenues

  As previously mentioned, effective with the merger and the ten year base
rate freeze, the Company discontinued the application of SFAS No. 71,
resulting in a change in its method of accounting for revenues. Previously,
substantially all revenues were recorded when billed. Under the unbilled
method, gas operating revenues are accrued based upon the amount of gas
delivered to utility customers through the end of the accounting period.
Accrued Utility Margin of $2,414,000 and $2,285,000, as reported in the
Consolidated Balance Sheets at December 31, 1999 and 1998, respectively,
represent the accrual of unbilled operating revenues net of related gas costs.
The impact on Transition Period earnings due to this change was an increase in
margin of $2,285,000.

 Cost of Gas Adjustment Clause and Deferred Gas Costs

  The CGAC requires the Company to adjust its rates semi-annually for firm gas
sales to track changes in the cost of gas distributed, with an annual
adjustment of subsequent rates for any over or under recovery of 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 local distribution adjustment clause
("LDAC") allows the Company to recover from all firm customers the
amortization of environmental response costs associated with former
manufactured gas plant ("MGP") sites and FERC Order 636 transition costs.
These costs were previously recovered through the CGAC. Upon the
discontinuance of the application of SFAS No. 71 as of September 30, 1998, the
Company records amounts recoverable under the LDAC as revenue when it is
billable to its customers.

 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 for the year ended December 31,
1999, was 3.70% and for the Transition Period, was 3.69%. For the fiscal years
ended August 31, the composite rate was 3.70% in 1998 and 3.53% in 1997.

  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.

 Pending Accounting Changes

  SFAS No. 133, "Accounting for Derivative Instruments and Hedging
Activities", as amended by SFAS No. 137, is effective for fiscal quarters of
all fiscal years beginning after June 15, 2000. SFAS No. 133 establishes
accounting and reporting standards requiring that every derivative instrument
(including certain derivative instruments embedded in other contracts) be
recorded in the balance sheet as either an asset or a liability measured at
its fair value. SFAS No. 133 requires that changes in the derivative's fair
value be recognized

currently in earnings unless specific hedge accounting criteria are met.
Special accounting for qualifying hedges allows a derivative's gains and
losses to offset related results on the hedged item in the income statement,
and requires that a company must formally document, designate and assess the
effectiveness of transactions that receive hedge accounting. The Company has
not yet quantified the impact of adopting SFAS No. 133 on the consolidated
financial statements. However, SFAS No. 133 could increase volatility in
earnings and other comprehensive income.

 Reclassifications

  Certain prior year financial statement amounts have been reclassified for
consistent presentation with the current year.

(3) Income Taxes

  For the year ended December 31, 1999, and for the Transition Period ended
December 31, 1998, the Company was a member of an affiliated group of
companies that files a consolidated federal income tax return. For the years
ended August 31, 1998 and August 31, 1997, the Company was a member of a
different consolidated group. The Company follows the policy, established for
the group, of providing for income taxes that would be payable on a separate
company basis. The Company's effective income tax rate was 36.5% for the year
ended December 31, 1999, 9.7% for the Transition Period ended December 31,
1998 and 36% and 36.6% for the fiscal years ended August 31, 1998 and August
31, 1997, respectively. State taxes represent the majority of the difference
between the effective rate and the Federal income tax rate for August 31, 1997
and August 31, 1998. For the transition period ended December 31, 1998 and for
the year ended December 31, 1999, non-deductible merger related costs were the
major component affecting the effective tax rate.

  Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases. Deferred tax assets and liabilities are measured using enacted tax
rates expected to apply to taxable income in the years in which those
temporary differences are expected to be recovered or settled. Generally, the
effect on deferred tax assets and liabilities of a change in tax rates is
recognized in income in the period that includes the enactment date. The
Company recognized a 1% rate difference in the transition period ended
December 31, 1998 due to becoming a member of an affiliated group of companies
taxed at the 35% statutory rate.

  For income tax purposes, the Company uses accelerated depreciation and
shorter depreciation lives, as permitted by the Internal Revenue Code.
Deferred federal and state taxes are provided for the tax effects of all
temporary differences between financial reporting and taxable income.
Significant items making up deferred tax assets and liabilities at December
31, 1999 and 1998 are as follows:

(6) Retiree Benefits (continued)

  The health care inflation rate for 2000 is assumed to be 8.0% and 10.0% for
pre-65 and post-65 health care benefits, respectively. The rate is assumed to
decrease gradually to 5.0% in 2006 for pre-65 benefits (2008 for post-65
benefits) and remain at that level thereafter. A one percentage point increase
or decrease in the assumed health care trend rate for 1999 would have the
following effects:

(8) Fair Values of Financial Instruments

  The following methods and assumptions were used to estimate the fair values
of financial statements:

    Cash and Cash Equivalents--The carrying amounts approximate fair value.

    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.

  The carrying amounts and estimated fair values of the Company's long-term
debt for the periods noted below are as follows:

</TABLE>

(9) Related Party Transactions

  The Company incurred $400,000 in 1999 for legal, tax and corporate services
provided by Eastern. Included in the Consolidated Balance Sheet at December 31,
1999 is a note payable to Eastern in the amount of $4,000,000. Interest is
charged based on the quarterly short-term applicable federal rate issued by the
Internal Revenue Service, and was 5.45% as of December 31, 1999.

  Substantially all of the administrative functions and information technology
systems are integrated with those of Boston Gas Company, an affiliated company.
As allowed by the Department, Essex is charged for only those costs
incrementally incurred to provide these services.

(10) Environmental Matters

  The Company, like many other companies in the natural gas industry, is party
to governmental proceedings requiring investigation and possible remediation of
former manufactured gas plant ("MGP") operations, including former operating
plants and a gas holder site. The Company may have or share responsibility
under applicable environmental laws for the remediation of four former MGP's
and one former gas holder site, as well as for one non-MGP site. The Company
has estimated its potential share of the costs of investigating and remediating
these sites in accordance with SFAS No. 5, "Accounting for Contingencies," and
the American Institute of Certified Public Accountants Statement of Position
96-1, "Environmental Remediation Liabilities." The Company has recorded a
liability of approximately $300,000, which represents its best estimate at this
time of remediation costs. However, there can be no assurance that actual cost
will not vary considerably from this estimate. Factors that may bear on actual
costs differing from estimates include, without limit, changes in regulatory
standards, changes in remediation technologies and practices and the type and
extent of contaminants discovered at the sites.

  The Company has received and responded to Requests for Information from the
U.S. Environmental Protection Agency ("EPA") pursuant to Section 104 of the
Comprehensive Environmental Response, Compensation and Liability Act
("CERCLA"), regarding two federal superfund sites that the EPA is currently
investigating. It is not possible at this time to reasonably estimate the
amount of the Company's obligation for remediation of the sites; however, the
Company expects that its share, if any, will be de minimis.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

(10) Environmental Matters (continued)

  By a rate order issued on May 25, 1990, the Department approved recovery of
all prudently incurred environmental response costs associated with former MGP
related sites over separate, seven-year amortization periods, without a return
on the unamortized balance. The Company currently believes, in light of the
Department rate order, that it is not probable that actual costs will
materially affect its financial condition or results of operations.

  The significant increase in operating expenses for the four months ended
December 31, 1998 as compared to the four months ended December 31, 1997, is
primarily due to merger related expenses as discussed in Note 1.

  This financial information is presented herein for comparative purposes and
includes any adjustments which are, in the opinion of management, necessary
for a fair presentation.

(12) Merger

  On November 4, 1999, Eastern signed a definitive agreement to be acquired by
KeySpan Corporation. Subject to receipt of satisfactory regulatory approvals
and the approval of Eastern shareholders, the transaction is expected to close
in mid to late 2000, although it is possible that the transaction will not
close until 2001.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Essex Gas Company:

  We have audited the accompanying consolidated balance sheets of Essex Gas
Company (a Massachusetts corporation and wholly owned subsidiary of Eastern
Enterprises) and subsidiary as of December 31, 1999 and 1998, and the related
consolidated statements of income, retained earnings and cash flows for the
year ended December 31, 1999, for the four-month period ended December 31,
1998, and each of the two years in the period ended August 31, 1998. These
consolidated financial statements and schedules are the responsibility of the
Company's management. Our responsibility is to express an opinion on the
financial statements based on our audits.

  We conducted our audits in accordance with auditing standards generally
accepted in the United States. 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 Essex Gas Company and
subsidiary as of December 31, 1999 and 1998, and the results of its operations
and its cash flows for the year ended December 31, 1999, the four-month period
ended December 31, 1998, and each of the two years in the period ended August
31, 1998, in conformity with accounting principles generally accepted in the
United States.

  Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The schedules listed in the index to
consolidated financial statements are presented for purposes of complying with
the Securities and Exchange Commission's rules and are not a part of the basic
financial statements. These schedules have been subjected to the auditing
procedures applied in the audits of the basic financial statements and, in our
opinion, fairly state, in all material respects, the financial data required
to be set forth therein in relation to the basic financial statements taken as
a whole.

  As discussed in Note 1, as a result of the merger, the approved rate plan
and related discontinuance of SFAS No. 71, the Company changed certain
accounting practices to comply with generally accepted accounting principles
for non-regulated entities.

                                                Effective July 1, 1995
                                                CGT Contract No. 2065
                                                FT-A Contract No. 2066

Dear John:

Pursuant to Essex's election, effective July 1, 1995, 388 Dth/d of capacity was
converted to a FT-A rate schedule (under FT-A contract No. 2066) from the above
referenced CGT contract.

Amendments to both contracts were prepared electronically on Tenn-Speed 2 for
Essex's execution, however, Tenn-Speed 2 rejected the amendment to effectively
reduce the CGT contract, while correctly transmitting the FT-A amendment which
Essex executed on-line. A special validation on CGT contracts is the problem.
This incident has been reported, but as of this date, this validation has not
been changed.

Since the Tenn-Speed 2 system does not recognize a reduction under the CGT
contract, the billing for the CGT contract has been incorrect beginning with
July's invoice. Our Information Services department is working on the problem,
and as soon as they determine when it will be resolved, we will let you know.

To minimize confusion and to verify the correct Dth's for billing and
transportation purposes under these contracts, please note the following:

                           Previous        Amount                    New
                             MDQ      Converted 07/01/95      Effective 07/01/95
                             ---      ------------------      ------------------

CGT Contract No. 2065    1,033 Dth         -388 Dth                645 Dth

FT-A Contract No. 2066     588 Dth         +388 Dth                976 Dth

We apologize for the inconvenience this is causing. The CGT amendment will be
made effective July 1, 1995 and you will see a retroactive adjustment on your
invoice.

If you have any questions, please give me a call at (713) 757-3562 or Bill Weber
at (713) 757-3387.

                                    Very truly yours,

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

                         ARTICLE I - SCOPE OF AGREEMENT

Following the commencement of service hereunder, in accordance with the terms of
Transporter's Rate Schedule FS, and of this Agreement, Transporter shall receive
for injection for Shipper's account a daily quantity of gas up to Shipper's
Maximum Injection Quantity of 5,476 dekatherms (Dth) and Maximum Storage
Quantity (MSQ) of 821,460 (Dth) (on a cumulative basis) and on demand shall
withdraw from Shipper's storage account and deliver to Shipper a daily quantity
of gas up to Shipper's Maximum Daily Withdrawal Quantity (MDWQ) of 10,466 Dth;
provided however, that when Shipper's storage balance is equal to or less than
30% of the MSQ but greater than 20% of the MSQ, the Maximum Daily Withdrawal
Quantity shall be 9,425 Dth; and provided further, that when Shipper's storage
balance is less than or equal to 20% of the MSQ, the Maximum Daily Withdrawal
Quantity shall be 5,207 Dth. For demand charge purposes, the MDWQ for balances
greater than 30% of the MSQ shall be used.

                           ARTICLE II - SERVICE POINT

The point or points at which the gas is to be tendered for delivery by
Transporter to Shipper under this Agreement shall be at the storage service
point at Transporter's Compressor Station 313.

                               ARTICLE III - PRICE

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


2.    Shipper agrees to reimburse Transporter for any filing or similar fees,
      which have not been previously paid by Shipper, which Transporter incurs
      in rendering service hereunder.
<PAGE>

3.    Shipper agrees that Transporter shall have the unilateral right to file
      with the appropriate regulatory authority and make changes effective in
      (a) the rates and charges applicable to service pursuant to Transporter's
      Rate Schedule FS, (b) the rate schedule(s) pursuant to which service
      hereunder is rendered, or (c) any provision of the General Terms and
      Conditions applicable to those rate schedules. Transporter agrees that
      Shipper may protest or contest the aforementioned filings, or may seek
      authorization from duly constituted regulatory authorities for such
      adjustment of Transporter's existing FERC Gas Tariff as may be found
      necessary to assure Transporter just and reasonable rates.

        ARTICLE IV - INCORPORATION OF RATE SCHEDULE AND TARIFF PROVISIONS

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

                          ARTICLE V - TERM OF AGREEMENT

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

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

                              ARTICLE VI - NOTICES

notice to the other.

                            ARTICLE VII - ASSIGNMENT

Any company which shall succeed by purchase, merger or consolidation to the
properties, substantially as an entirety, of Transporter or of Shipper, as the
case may be, shall be entitled to the rights and shall be subject to the
obligations of its predecessor in title under this Agreement. Otherwise no
assignment of the Agreement or any of the rights or obligations thereunder shall
be made by Shipper, except pursuant to the General Terms and Conditions of
Transporter's FERC Gas Tariff.

It is agreed, however, that the restrictions on assignment contained in this
Article shall not in any way prevent either Party to the Agreement from pledging
or mortgaging its rights thereunder as security for its indebtedness.

                          ARTICLE VIII - MISCELLANEOUS

8.1   The interpretation and performance of this Agreement shall be in
      accordance with and controlled by the laws of the State of Texas, without
      regard to doctrines governing choice of law.

8.2   If any provision of this Agreement is declared null and void, or voidable,
      by a court of competent jurisdiction, then that provision will be
      considered severable at either Party's option; and if the severability
      option is exercised, the remaining provisions of the Agreement shall
      remain in full force and effect.
<PAGE>

8.3   Unless otherwise expressly provided in this Agreement or Transporter's
      Tariff, no modification of or supplement to the terms and provisions
      stated in this Agreement shall be or become effective, until Shipper has
      submitted a request for change through the TENN-SPEED 2 System and Shipper
      has been notified through TENN-SPEED 2 of Transporter's agreement to such
      change.

8.4   Transporter and Shipper agree that this Agreement, as of the date hereof,
      shall supersede and cancel the Gas Storage Contract Number 2272, dated
      September 1, 1993 between the Parties hereto.


IN WITNESS WHEREOF, the Parties have caused this Agreement to be duly executed
by their authorized agents.

                                             Service Package No. 2272

Dear Allen:

TENNESSEE GAS PIPELINE COMPANY (TENNESSEE) AND ESSEX COUNTY GAS CO (ESSEX) agree
to amend the above referenced gas storage contract effective July 1, 1995, to
increase the Maximum Daily Withdrawal Quantity (MDWQ) when Shipper's storage
balance is equal to or less than 30% of the Maximum Storage Quantity (MSQ) and
20% of the MSQ, respectively, as reflected in the attached Exhibit A-1 and as
described below.

The parties agree to amend Article I of the subject gas storage contract as
follows:

Following the commencement of services hereunder, in accordance with the terms
of Transporter's Rate Schedule FS, and of this Agreement, Transporter shall
receive for injection for Shipper's account a daily quantity of gas up to
Shipper's Maximum Injection Quantity of 5,476 dekatherms (Dth) and Maximum
Storage Quantity (MSQ) of 821,460 (Dth) (on a cumulative basis) and on demand
shall withdraw from Shipper's storage account and deliver to Shipper a daily
quantity of gas up to Shipper's Maximum Daily Withdrawal Quantity (MDWQ) of
10,466 Dth; provided however, that when Shipper's storage balance is equal to or
less than 30% of the MSQ but greater than 20% of the MSQ, the Maximum Daily
Withdrawal Quantity shall be 9,540 Dth; and provided further, that when
Shipper's storage balance is less than or equal to 20% of the MSQ, the Maximum
Daily Withdrawal Quantity shall be 5,322 Dth. For demand charge purposes, the
MDWQ for balances greater than 30% of the MSQ shall be used.

Except as amended herein, all terms and provisions of the above referenced gas
storage contract shall remain in full force and effect as written.

If the foregoing is in accordance with your understanding of our agreement,
please so indicate by signing and returning to my attention both originals of
this letter. Upon Tennessee's execution, an original will be forwarded to you
for your files.

RE: CONTRACT RESTRUCTURING LETTER AGREEMENT

Dear Bill:

      This Contract Restructuring Letter Agreement ("Letter Agreement") is
entered into by and between Tennessee Gas Pipeline Company ("Tennessee"), Boston
Gas Company ("Boston Gas") and Essex County Gas ("Essex") (Boston Gas and Essex
are referred to collectively as "Shippers"). Whereas, Tennessee, Boston Gas and
Essex (being hereinafter referred to as a "Party" and collectively referred to
as the "Parties"), have agreed upon the terms and conditions under which to
extend and amend certain Firm Transportation and Storage Service Agreements
("Firm Agreements") to restructure the firm services received by Shippers from
Tennessee (hereinafter referred to as "Contract Restructuring"). The Parties
wish to proceed with the Contract Restructuring based on the following terms and
principles subject to the execution and regulatory approval of final agreements
effectuating the provisions described herein.

1.    Primary Point Amendment

      Subject to Shippers' participation in an open season to change primary
      points in accordance with Article XXVIII, Section 5.7 of the General Terms
      and Conditions of Tennessee's FERC Gas Tariff, Tennessee shall allow
      Shippers to amend the Firm Agreements identified below to effectuate a
      change in primary receipt points from meters located in Zones 00, 0L, and
      01 to meter number 07-0018, Tennessee's Northern Storage Withdrawal
      (located in Tennessee's Zone 4) to be effective in accordance with the
      quantity limitations detailed in Appendix A attached hereto. The reduction
      of primary firm receipt meter TQ by the applicable percentages and
      resulting quantities from the current primary receipt points in Zones 00,
      0L, and 01 shall be implemented pro-rata across the Firm Agreements
      identified below at all affected meters. Thus, the currently existing
      Zones 00, 0L, and 01 primary receipt points by Firm Agreement shall each
      be reduced individually by the applicable amendment percentage and meter
      number 07-0018
<PAGE>

Contract Restructuring Letter Agreement
August 2, 1999
Page 2

      shall be increased by the like quantity so that the receipt quantity of
      each Firm Agreement is thereby preserved.

      As detailed below, Essex' decision regarding renewal of 100% of the
      current MDQ on Essex' FT-A Agreement No. 8518 for a period of three years
      impacts the allowable amendment percentage available to Shippers. The
      table below briefly outlines the allowable amendment percentages by Firm
      Agreement number:

                                                      K#            10/31/2003
                                                      --            ----------

      Retain 100% of Firm Agreements                 2062               15%
      (Identified in Item 2 below)
      Inclusive of FT-A Agreement 8518               8518               15%

      Retain 100% of Firm Agreements                 2062               15%
      (Identified in Item 2 below)
      Exclusive of FT-A Agreement 8518               8518               N/A

      Appendix A also details the associated buyout amounts by Firm Agreement.
      The buyout amounts outlined in Appendix A are equivalent to 60% of the
      effective upstream (Zones 00/01 to Zone 04) annual demand charge
      multiplied by the applicable amendment quantity. The buyout payment will
      be due to Tennessee prior to October 31, 1999.

2.    Term

      Subject to Shipper's amendment of the Firm Agreements as described in Item
      1 above, Shippers shall elect to extend 100% of the currently existing
      Transportation Quantity ("TQ") or Maximum Storage Quantity ("MSQ"), as
      applicable, of each of the following Firm Agreements pursuant to Article
      III, Section 10.5 of the General Terms and Conditions of Tennessee's FERC
      Gas Tariff for a period of three years, such that the subsequent
      expiration date of each of the Firm Agreements is October 31, 2003: Boston
      Firm Agreement Nos. 20241, 623, 2062, and 527; Essex Firm Agreement Nos.
      577 and 2272. Each extension shall continue the Primary Extended Term as
      outlined in Section 10.5. Unless otherwise expressly agreed by Tennessee,
      as applicable, Shippers currently existing Maximum Daily Injection
      Quantity, Maximum Daily Withdrawal Quantity and ratchet levels shall
      remain in effect through the Primary Extended Term in each applicable Firm
      Agreement.
<PAGE>

Contract Restructuring Letter Agreement
August 2, 1999
Page 3

      At Essex' option, on or before September 30, 1999, Essex will submit a
      rollover election pursuant to Article III, Section 10.5 of the General
      Terms and Conditions of Tennessee's FERC Gas Tariff to extend up to 100%
      of the current MDQ of Essex' FT-A Agreement 8518 for a period of three
      years, such that the subsequent expiration date of the FT-A Agreement is
      October 31, 2003. This extension shall constitute the Primary Extended
      Term as outlined in Section 10.5.

      In the event Essex elects by September 30, 1999 to extend 100% of the
      current MDQ of the FT-A Agreement, Tennessee agrees to allow Essex to
      amend its primary receipt zone in accordance with Tennessee's FERC Gas
      Tariff as described in Item 1 above.

3.    Rate

      Subject to Shipper's amendment of the Firm Agreement as described in Item
      1 above and to Shipper's extension of the FT-A Agreements as described in
      Item 2 above and for the period commencing November 1, 1999 and extending
      through the Primary Extended Term, Shippers shall pay a negotiated rate
      for service comprised of the following: (1) Tennessee's Base Reservation
      Rate effective as of November 1, 1999; and (2) Tennessee's Base Commodity
      Rate effective as of November 1, 1999. In addition, Shippers shall pay all
      then-effective surcharges and applicable fuel. (The rates are therefore
      fixed, but the surcharges and fuel charges are not).

      Subject to Shipper's amendment of the Firm Agreements as described in Item
      1 above and to Shipper's extension of the FS-MA Agreements as described in
      Item 2 above and for the period commencing November 1, 1999 and extending
      through the Primary Extended Term, Shippers shall pay a negotiated rate
      for service comprised of the following: Tennessee's Tariff Rate effective
      as of November 1, 1999 for deliverability, space, injection, withdrawal
      and overrun. In addition, Shippers shall pay all then-effective surcharges
      and applicable fuel. (The rates are therefore fixed, but the surcharges
      and fuel charges are not).

      During the period defined above, this Letter Agreement shall be the sole
      agreement between the Parties affecting the rates.

4.    National Fuel/Tennessee Northern Storage Receipt Point Amendment

      Pursuant to the NPV open season process outlined in Section 5.7 of Article
      XXVIII of Tennessee's FERC Gas Tariff on or before August 31, 1999,
      Shippers will submit an amendment request effective April 1, 2000 or
      November 1, 2000 to amend approximately 5,945 Dth/d of receipt point
      capacity on Boston Gas' FT-A Agreement No. 20241 and 807 Dth/d of receipt
      point capacity on Essex's FTA Agreement No. 10788 from the National Fuel
      Andrews Settlement receipt point (meter number 1-1693) to Tennessee
      Northern Storage (meter number 7-0018).
