ITEM 1.   DESCRIPTION OF PROPOSED TRANSACTION

        This is an application under the Public Utility Holding Company Act of
1935 (the "Act") by Eastern Enterprises ("Eastern") for approval of its
acquisition, through a so-called reverse triangular merger, of all the
outstanding capital stock of Essex County Gas Company ("Essex"), a Massachusetts
gas utility company. Eastern is a holding company exempt from registration under
the Act pursuant to the "intrastate" exemption of Section 3(a)(1). Currently,
its sole utility subsidiary is Boston Gas Company ("Boston Gas"), a
Massachusetts gas utility company. Following the proposed acquisition, Eastern
will have two gas utility subsidiaries, both located in Massachusetts, and will
continue to satisfy the requirements of Section 3(a)(1). In addition, Essex and
Boston Gas together will constitute an integrated public-utility system because,
among other things, they have contiguous service areas and common sources of
supply.

        Eastern is a Massachusetts voluntary association created by a
Declaration of Trust dated July 18, 1929, as amended, and is exempt under
Section 3(a)(1) of the Act pursuant to orders dated February 28, 1955 (Pub.
Util. Holding Company Act of 1935 Release No. 12807), November 3, 1967 (Pub.
Util. Holding Company Act of 1935 Release No. 15887) and August 28, 1975 (Pub.
Util. Holding Company Act of 1935 Release No. 19100) .

        Eastern is the sole stockholder of all issued and outstanding common
stock of Boston Gas, a Massachusetts corporation engaged in the gas utility
business. Boston Gas serves approximately 530,000 customers, all in
Massachusetts. Boston Gas has outstanding 1,200,000 shares of non-voting
preferred stock, which are held by the public.

        Essex is a regulated public utility and a non-affiliated Massachusetts
corporation engaged in the gas utility business. Essex serves over 42,000
customers in the Commonwealth of Massachusetts. Essex's service territory is
contiguous to Boston Gas' service territory.

A.  PROPOSED ACQUISITION OF ESSEX
- ---------------------------------

        Eastern and Essex have agreed, subject to various approvals including
approval from the Securities and Exchange Commission (the "Commission"), that
Eastern will acquire Essex through a merger into Essex of a subsidiary of
Eastern formed for that purpose. After the merger, Eastern will own all the
outstanding capital stock of Essex, and the former stockholders of Essex will
hold shares of common stock of Eastern. Eastern's common stock is traded on the
New York Stock Exchange, the Boston Stock Exchange and the Pacific Stock
Exchange. Based on reported prices for Eastern shares on those exchanges in
December 1997, when the merger was announced, the Eastern shares to be issued
would have a market value of approximately $80.5 million and would constitute
approximately 9.3% of Eastern's outstanding stock. The terms and conditions




                                       2



<PAGE>   3

agreed upon between Eastern and Essex, are set forth in the Merger Agreement
included as Exhibit B hereto (the "Agreement").

        The Agreement between Eastern and Essex was the result of a process
conducted by Essex to explore strategic alternatives.

        Included with this Application as Exhibit D-1 is a copy of the Joint
Petition of Eastern Enterprises and Essex County Gas Company For Approval of
Merger submitted on February 27, 1998 to the Massachusetts Department of
Telecommunications and Energy (the "DTE Petition"), including exhibits. The
Massachusetts Department of Telecommunications and Energy (the "MDTE") will
schedule a hearing on the petition and will issue an order approving or
disapproving the merger.

        Also included hereto as Exhibit C is a copy of the Registration
Statement (the "Registration Statement") on Form S-4, filed by Eastern, which
includes the Proxy Statement of Essex as filed with the Commission (the "Essex
Proxy Statement") in connection with the proposed special meeting of Essex
stockholders to approve the Merger.

1.      Description of Business of Essex and Eastern

        Essex is a gas utility whose principal business is the distribution and
sale of natural gas. Essex has 12 directors, including the President and Chief
Executive Officer and five other officers. Essex sells natural gas to over
42,000 customers in eastern Massachusetts. Essex's service territory in eastern
Massachusetts is contiguous to Boston Gas' service territory. The size of
Essex's customer base has been growing in recent years, with 820 new customers
added during fiscal 1997.

        Essex net earnings for the twelve months ended August 31, 1997, was
$3,966,519 on revenues of $53,534,734.

        Essex had a total of approximately 127 permanent employees on August 31,
1997.

        Eastern is exclusively a holding company. Its sole utility subsidiary is
Boston Gas, a distributor of natural gas, serving approximately 530,000
residential, commercial and industrial customers in Boston and 73 other eastern
and central Massachusetts communities. In addition, Eastern has several
non-utility subsidiaries, including primarily Midland Enterprises Inc., a
carrier of coal and other dry bulk cargoes on the nations inland waterways, with
a fleet 2,302 dry cargo barges and 87 towboats.

2.      Acquisition of Essex

        The terms and mechanism for acquiring Essex are set forth in the
Agreement described in the prospectus included in the Registration Statement. In
brief, they include the following:



                                       3


<PAGE>   4

(a)     Eastern will form a temporary Massachusetts corporation ("NEWCO") as a
        wholly-owned subsidiary of Eastern;*

(b)     NEWCO will merge with and into Essex, with Essex as the surviving
        corporation (the "Surviving Corporation") having all the rights,
        interests, and obligations of Essex;

(c)     Shares of NEWCO will be converted into shares of new common stock of the
        Surviving Corporation, with the Surviving Corporation being a wholly
        owned subsidiary of Eastern; and

(d)     Each outstanding share of Essex will be converted into 1.183985 shares
        of Eastern common stock subject to adjustment under certain
        circumstances based on the average market price for a specified period
        prior to closing, so that the stockholders of Essex will become
        stockholders of Eastern.

        The merger will become effective at the time of filing of the Articles
of Merger with the Secretary of State of the Commonwealth of Massachusetts. The
closing will be held only upon the satisfaction (or waiver, where permissible)
of certain conditions contained in the Agreement, including obtaining necessary
approvals from the MDTE, the Commission, and other government agencies.

3.      Common Shares Issued by Eastern

        The initial exchange ratio is 1.183985 shares of Eastern common stock
for each issued and outstanding share of Essex common stock. The actual number
of Eastern shares to be issued will be adjusted to provide that the value of the
Eastern common stock to be issued for each Essex common stock share will not be
less than $45 nor more than $50, based upon the average market price during a
specified period prior to closing. Eastern will register with the Commission
shares of its common stock for this purpose. (See Exhibit C hereto). This
acquisition price is reasonable in the opinion of Salomon Smith Barney,
Eastern's investment banking advisors, and will not result in any excessive
charges to Boston Gas or Essex rate payers. See Item 4(e) below.

        Eastern's common shares are listed on the New York, Boston and Pacific
Stock Exchanges. From January 1, 1997 through December 31, 1997, the price for
Eastern's shares on the New York Stock Exchange -- Composite Transactions ranged
from a high of $45.375 to a low of $30.50. Essex's common shares are quoted on
NASDAQ. From January 1, 1997 through December 31, 1997, the price for Essex's
shares on NASDAQ ranged from a high of $49.00 to a low of $24.25.


- ------------------
*Newco will be formed under the Massachusetts statute relating to gas companies,
but will not own or operate any utility assets before consummation of the merger
and will disappear upon consummation of the merger.

<PAGE>   5

4.      Compliance with Section 10

        The proposed acquisition meets all the substantive requirements of
Section 10 of the Act. Specifically, the Commission should find that the
acquisition complies with subsections (c) and (f) on the basis of the following:

        a. The acquisition is lawful under Section 8 of the Act and is not
detrimental to the carrying out of the provisions of Section 11.

        Both Essex and Boston Gas are retail gas distribution companies, with no
electric utility assets or operations.

        The resulting holding company system of Eastern will continue to be
exempt from registration under the Act pursuant to the "intrastate" exemption
provided in Section 3(a)(1), because Eastern and all of its utility
subsidiaries, Essex and Boston Gas, will continue to be organized under
Massachusetts law, and their combined utility operations will be carried on
solely in Massachusetts. See service area map, Exhibit E.

        b. The acquisition will serve the public interest by tending toward the
economical and efficient development of an integrated public-utility system.

        As the map attached as Exhibit E shows, the service areas of Essex and
Boston Gas are contiguous, and both companies receive a substantial portion of
their natural gas supplies from the Tennessee Gas Pipeline Company. Eastern
expects to derive substantial cost savings from the combined operations of Essex
and Boston Gas, including savings from sharing of their combined pipeline supply
capacity (DTE Petition, Testimony of William R. Luthern, p. 2) and savings from
consolidation of management positions and other duplicated administrative costs
(DTE Petition, Testimony of Joseph F. Bodanza, pp. 8-10). In addition, the
companies expect to attain more efficient service to customers by combining
their dispatch, telephone inquiry, and customer service operations (Id. at pp.
10-11).

        c. Massachusetts law applying to the acquisition has been complied
with.

        By its terms, the merger will not be consummated unless it is approved
by the MDTE under applicable provisions of Chapter 164 of the Massachusetts
General Laws. Eastern will provide to the Commission a copy of the MDTE's order
approving the merger as soon as it is available.

        In addition, there is no basis for making any of the negative findings
that would prevent approval of the proposed acquisition under subsection (b) of
section 10, for the following reasons:

        d. The acquisition will not tend toward any interlocking relations or
undue concentration of control of public-utility companies in Massachusetts.



                                       5



<PAGE>   6

        As indicated above, after the proposed acquisition, Essex will be a
wholly owned direct subsidiary of Eastern, as Boston Gas now is. As usual in
holding-company systems, Essex and Boston Gas may have officers and directors in
common, some of whom may also be officers of Eastern; but that mode of common
management of the integrated system of subsidiaries is not the sort of
"interlocking relationship" that the Act is intended to prevent.

        The combination of Essex and Boston Gas will not substantially increase
the size of Eastern's utility subsidiary operations. Boston Gas currently serves
approximately 530,000 retail gas customers in 74 cities and towns in eastern and
central Massachusetts. Together, Essex and Boston Gas will serve a base of
approximately 572,000 retail gas customers in a contiguous service area
comprising 91 cities and towns in eastern and central Massachusetts. Boston Gas
had assets of $878.2 million at December 31, 1997 and revenues of $700.9 million
for the year then ended. Essex and Boston Gas together will have pro forma
combined assets of $974.0 million and pro forma combined revenues of $755.4
million.

        e. The consideration to be paid is reasonable and bears a fair relation
to the value of the utility assets underlying the securities to be acquired.

        The price to be paid by Eastern was determined by bids in a process
conducted by Essex, in which Eastern was one of five bidders. See DTE
Application, testimony of James H. Hastings, pp. 4-8. The investment banking
firm of Furman Selz, LLC advised the Board of Directors of Essex that the
exchange ratio was fair to the stockholders of Essex from a financial point of
view (see Essex Proxy Statement, pp. 26-30); and the investment banking firm of
Salomon Smith Barney has advised the Trustees of Eastern that the merger price
is reasonable, is consistent with recent history of mergers in the natural gas
industry, and is not likely to result in excessive charges against the earnings
of Eastern or Boston Gas (see DTE Petition, Testimony of Paul J. Murphy).

        In addition, Eastern and Essex have proposed to the MDTE a rate plan
that will effect an immediate reduction in the retail gas price charged to
customers of Essex and a ten-year freeze on the base rates for Essex, to reflect
expected cost savings that would result from combined operation of Essex and
Boston Gas. See DTE Petition, Testimony of Joseph S. Bodanza. The plan also
contemplates a transfer from Essex to Boston Gas under the two companies'
respective Cost of Gas Adjustment Clauses, to compensate Boston Gas customers
for Essex's use of combined gas purchasing with Boston Gas to achieve savings.
Id. at p. 5.

        Under Massachusetts law, retail gas rates are regulated by the MDTE,
which has full power to examine transactions with affiliates and to allow or
disallow intercompany costs and charges in the rate-setting process. Mass.
General Laws, c. 164, secs. 76A, 85, 94. Thus, the financial effect of the
merger price on customers of Essex and of Boston Gas is subject to effective
regulation by the applicable state authority.



                                       6



<PAGE>   7

        f. The acquisition will not unduly complicate the capital structure of
Eastern's holding-company system and will not be detrimental to the public
interest, the interest of investors or consumers, or the proper functioning of
the holding-company system.

        The merger price will consist solely of shares of Eastern's voting
common stock, of the class that is publicly traded on the New York Stock
Exchange, the Pacific Stock Exchange, and the Boston Stock Exchange. There will
be no debt and no preferred or senior securities involved. There will be no
minority voting stock interest in either Essex or Boston Gas: both will be
wholly-owned subsidiaries of Eastern. As the Testimony of Paul J. Murphy in the
DTE Petition explains, the dilution to be experienced by stockholders of Eastern
is reasonable in view of the value of the assets being acquired. The interests
of gas consumers are protected by the jurisdiction of the MDTE. As outlined in
Item 1(a)(4)(b) above, the acquisition will serve the public interest by
promoting the economical and efficient development of an integrated
public-utility system.

ITEM 2.  FEES, COMMISSIONS AND EXPENSES
- ---------------------------------------

        The estimated fees and expenses in connection with the proposed
transactions are set forth in Exhibit G hereto.

ITEM 3.  APPLICABLE STATUTORY PROVISIONS
- ----------------------------------------

        Sections 9(a) and 10 of the Act are applicable to the acquisition by
Eastern of shares of capital stock of Essex.

ITEM 4.  REGULATORY APPROVAL
- ----------------------------

        The MDTE has jurisdiction over the proposed merger and certain matters
in connection therewith. The fact that the MDTE has jurisdiction over both
Boston Gas and Essex assures that the rates of both of these companies will be
just and reasonable and will not include unreasonable charges associated with
the merger. The proposed merger is subject to the satisfaction of the applicable
notification waiting period and approval by the Federal Trade Commission and the
Department of Justice pursuant to the Hart-Scott-Rodino Antitrust Improvements
Act of 1976, as amended. No other state regulatory commission and no other
federal commission (other than the Commission) has jurisdiction over the
proposed transactions.




                                       7
<PAGE>   8



ITEM 5.  PROCEDURE
- ------------------

        It is anticipated that the MDTE will issue a decision by mid-1998 on the
merger. It is requested that the Commission take action with respect to this
Application or Declaration without a hearing being held and that an order be
issued allowing this Application/Declaration to become effective at
approximately the same time.

        Eastern further requests that the Commission enter an order confirming
that Eastern's holding company system after consummation of the merger will
continue to be exempt from registration under the Act pursuant to the Commission
orders of February 8, 1955, November 3, 1967 and August 28, 1975 cited in the
Introduction above.

        Eastern (i) does not request a recommended decision by an administrative
law judge, (ii) does not request a recommended decision by any other responsible
officer of the Commission, (iii) hereby specifies that the Division of
Investment Management may assist in the preparation of the Commission's
decision, and (iv) hereby requests that there be no 30-day waiting period
between the date of issuance of the Commission's order and the date on which it
is to become effective.

           NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION


(1)  BOSTON GAS AND ESSEX COUNTY HISTORICAL FISCAL YEARS AND ACCOUNTING POLICIES

Boston Gas' historical fiscal year ends on December 31 while Essex County's
historical fiscal year ends on August 31. For purposes of combining Essex
County's historical financial information with Boston Gas' in the pro forma
combined statement of operations herein, the financial information of Boston Gas
for the fiscal year ended December 31, 1997 has been combined with Essex
County's financial information for the twelve months ended November 30, 1997.

The accounting policies of Eastern, Boston Gas and Essex County are currently
being studied from a conformity perspective. The impact of conforming accounting
policies (if any) is not presently estimable. If conforming adjustments are
required, they will be recorded as part of the restatement of prior periods as
required by the pooling-of-interests method. However, certain amounts in the
historical financial statements of Boston Gas and Essex County have been
reclassified to present consistent pro forma financial information. There were
no material intercompany transactions between Boston Gas and Essex County during
the periods presented.

(2)  MERGER-RELATED EXPENSES

Eastern and Essex County will incur investment banking, legal, accounting and
other transaction costs as a result of the Merger. Based on information
currently available, these costs will total approximately $4.6 million and have
been and will be expensed in the period incurred. Since the Merger has not been
consummated, the Merger expenses can only be estimated at this time, and are
subject to revision as further information becomes available.

(3)  COMMON STOCKHOLDERS' INVESTMENT

The common stock and paid-in capital accounts of Boston Gas and Essex County
have not been restated for the Merger due to the fact that Essex County common
stock is being exchanged for Eastern common stock, not Boston Gas common stock,
as provided in the Merger Agreement. The exchange ratio is one Essex County
common share for 1.183985 shares of Eastern common stock.

====================================

             JOINT PETITION OF EASTERN ENTERPRISES, MERGER CO., AND
                 ESSEX COUNTY GAS COMPANY FOR APPROVAL OF MERGER

     Now come Eastern Enterprises ("Eastern"), Essex County Gas Company
("Essex"), and Merger Co. (together, the "Parties"), and respectfully move that
the Department of Telecommunications and Energy (the "Department") approve the
following:

     (1)  the merger of Merger Co. and Essex, pursuant to G.L. c. 164, ss. 96;

     (2)  Essex's Rate Plan, pursuant to G.L. c. 164, ss. 94; and

     (3)  Merger Co.'s issuance and sale by Merger Co. of 100 shares of common
          stock, $1.00 par value, to Eastern in exchange for consideration of
          $100, pursuant to G.L. c. 164, ss. 14.

     In addition, Eastern and Essex request that the Department confirm that
Essex, as the surviving corporation of the merger between Merger Co. and Essex,
will continue to have all the franchise rights and obligations that were
previously held by Essex, and that further action, pursuant to G.L. c. 164, ss.
21, is not required to consummate the merger.


<PAGE>   2


In support thereof, the Parties state the following:

1.   Merger Co. is a gas company to be formed under G.L. c. 164, ss. 1, with a
     principal place of business in Boston, Massachusetts. Merger Co. will be a
     wholly owned subsidiary of Eastern.

2.   Eastern is a Massachusetts business trust established and existing under a
     Declaration of Trust dated July 18, 1929, as amended, with a principal
     place of business in Weston, Massachusetts.

3.   Essex is a Massachusetts gas company, pursuant to G.L. c. 164, ss. 1, with
     a principal place of business in Amesbury, Massachusetts.

4.   Eastern and Essex have entered into an Agreement and Plan of Merger dated
     December 19, 1997 (the "Merger Agreement"), which is subject to necessary
     approvals of government regulatory authorities having jurisdiction,
     providing for the merger of Merger Co. into Essex. As a result of the
     Merger Agreement, Essex will become a wholly owned subsidiary of Eastern. A
     copy of the Merger Agreement is attached hereto as Attachment 1.

5.   The Merger Agreement sets forth the following sequence of events that will
     result in Essex becoming a wholly owned subsidiary of Eastern:

     (a)  Eastern shall cause Merger Co. to be incorporated and to adopt charter
          documents and other organizational documents as may be necessary or
          appropriate to effect the purpose of the Merger.

     (b)  Essex shareholders will vote on the approval of the Merger Agreement.

     (c)  The Department and other regulatory agencies will review the Merger
          Agreement.


                                       2


<PAGE>   3


     (d)  Upon receipt of the necessary regulatory approvals, Merger Co. will be
          merged with and into Essex in accordance with the laws of the
          Commonwealth of Massachusetts. Essex will be the surviving corporation
          in the merger and will continue its corporate existence under the laws
          of the Commonwealth of Massachusetts.

     (e)  By virtue of the merger and without any action on the part of any
          holder of any capital stock of Essex or Merger Co: (i) each share of
          common stock of Merger Co. will be converted into one share of common
          stock of Essex, the surviving corporation; (ii) each share of Essex
          common stock, that is owned by Essex as treasury stock and all shares
          of Essex common stock that are owned, directly or indirectly, by Essex
          or Eastern or any of their respective wholly owned subsidiaries will
          be canceled and shall cease to exist; and (iii) each issued and
          outstanding share of Essex common stock, other than shares canceled
          pursuant to subclause (ii) of this paragraph, shall be converted into
          the right to receive 1.183985 shares of Eastern common stock. The
          actual number of Eastern shares to be issued will be adjusted to
          ensure that the value of Eastern common stock to be issued for each
          Essex share will not be less than $45.00 nor more than $50.00, based
          upon the average market price during a specified period prior to
          closing.

     (f)  Upon such conversion, each holder of a certificate formerly
          representing any shares of 

                                       3
<PAGE>   4


          Essex common stock shall cease to have any rights with respect
          thereto, except the right to exchange such certificates for shares of
          Eastern common stock to be issued in consideration of the surrender of
          such certificate in accordance with the Merger Agreement.

     (g)  Upon the completion of the conversion of Essex common stock for
          Eastern common stock, as described above, Essex will become a wholly
          owned subsidiary of Eastern.

6.   Merger Co.'s issuance and sale of 100 shares of its common stock to Eastern
     is reasonably necessary for the purpose for which such issue of stock has
     been authorized - namely, for the purpose of effecting the merger
     transaction.

7.   Consummation of the merger is subject to the satisfaction of certain
     conditions set forth in sections 8.1, 8.2 and 8.3 of the Merger Agreement.

8.   This application was authorized by the Board of Directors of Essex at a
     meeting duly called for that purpose and held on December 19, 1997.

9.   Votes of the shareholders of Essex approving the Merger Agreement and the
     terms thereof will be provided to the Department immediately upon their
     receipt. A vote of the shareholders is scheduled for May 19, 1998.

10.  The testimony of Messrs. Joseph F. Bodanza, Walter J. Flaherty, James H.
     Hastings, William R. Luthern, and Paul J. Murphy, explaining in detail the
     proposed transaction and its expected benefits, is attached hereto as
     Exhibits JFB-1, WJF-1, JHH-1, WRL-1 and PJM-1, respectively.

11.  The Rate Plan for Essex customers is submitted for Department approval,
     pursuant to G.L. c. 164, ss. 94, as fully described in the testimony of
     Joseph F. Bodanza (Exhibit JFB-1). The Rate Plan provides for an immediate
     5 percent reduction in the total burner-tip price paid by Essex customers.
     In addition, the 

                                       4


<PAGE>   5


     Rate Plan establishes a ten-year freeze in Essex's base rates, which will
     provide customers with significant price stability and additional savings
     through the avoidance of base-rate increases that customers would have
     otherwise experienced. As discussed in detail by Mr. Bodanza, the 5 percent
     reduction will be provided to Essex customers principally through gas cost
     savings, which will result from the attainment of synergies and
     efficiencies in the gas supply function. The ten-year base rate freeze will
     provide Essex customers with additional benefits of approximately $33
     million.

12.  It is necessary, expedient and in the public interest for the Merger
     Agreement to be approved by the Department in order to provide long-term
     advantages to Essex, its shareholders, customers and employees, and
     Eastern, its shareholders, customers of Boston Gas Company ("Boston Gas"),
     a wholly owned subsidiary of Eastern, and Eastern's employees (including
     employees of Boston Gas).

WHEREFORE, the Parties respectfully request that the Department:

     a.   Determine that the proposed merger and the terms thereof are
          consistent with the public interest; 

     b.   Approve the Merger Agreement and the merger of Merger Co. into Essex,
          pursuant to G.L. c. 164, ss. 96;

     c.   Vote pursuant to G.L. c. 164, ss. 14 that the proposed issuance of 100
          shares of Merger Co. common stock, $1.00 par value, to Eastern is
          reasonably necessary for the purposes stated;

                                       5

<PAGE>   6


     d.   Approve and authorize, pursuant to G.L. c. 164, ss. 14, the issuance
          by Merger Co. of 100 shares of Merger Co. common stock to Eastern in
          consideration of $100 by Eastern;

     e.   Approve the Rate Plan, pursuant to G.L. c. 164, ss. 94, as just and
          reasonable and consistent with the public interest.

     f.   Confirm that Essex, as the surviving corporation of the merger between
          Merger Co. and Essex, will continue to have all the franchise rights
          and obligations that were previously held by Essex, and that further
          action, pursuant to G.L. c. 164, ss. 21, is not required to consummate
          the merger; and

II.  BACKGROUND OF EASTERN ENTERPRISES

Q.   PLEASE DESCRIBE THE BACKGROUND AND OPERATIONS OF EASTERN ENTERPRISES.

A.   Eastern is an unincorporated voluntary association (commonly referred to as
     a "Massachusetts business trust") established and existing under a
     Declaration of Trust dated July 18, 1929, as amended. Eastern's principal
     subsidiaries are Boston Gas and Midland Enterprises, Inc. ("Midland").
     Boston Gas is engaged in the transportation and sale of natural gas to
     approximately 530,000 residential, commercial and industrial customers in
     Boston, Massachusetts and 73 other communities in eastern and central
     Massachusetts. Boston Gas has been in business for 175 years and is the
     second oldest gas company in the United States. Since 1929, all of the
     common stock of Boston Gas has been owned by Eastern.

     Midland transports coal and other dry bulk commodities on the Ohio and
     Mississippi Rivers and their tributaries, the Gulf Intracoastal Waterway
     and the Gulf of Mexico using a fleet of about 2,300 barges and 87 towboats.
     During 1997, Eastern formed two new subsidiaries to take advantage of
     opportunities being created by the restructuring of the energy industry.
     ServicEdge Partners, Inc., ("ServicEdge") is a fuel-neutral, full-service
     provider of heating, ventilation and air conditioning products and services
     and AMR Data Corporation ("AMR Data") provides meter services to electric,
     gas and water utilities throughout the Northeast. Eastern will also be
     forming Merger Co., under G.L. c. 164, as a Massachusetts corporation and a
     wholly owned subsidiary of Eastern for the specific purpose of effecting
     the transactions contemplated by the merger.

III. THE DECISION TO ACQUIRE ESSEX COUNTY GAS COMPANY

Q.   IN GENERAL, WHAT ARE THE BENEFITS THAT MERGERS AND ACQUISITIONS CAN PROVIDE
     TO UTILITY CUSTOMERS?

A.   Utility mergers and acquisitions throughout the United States have produced
     substantial benefits to customers in the form of operational synergies and
     cost savings that have either reduced customer rates and/or slowed the rate
     of growth in rates. These cost savings are generally not achievable in the
     absence of a merger or other business combination because such savings are
     typically attained as a result of integrating various corporate,
     administrative and field functions, re-optimizing energy resources and
     taking advantage of economies of scale, improved financial strength,
     operational diversity, and other related opportunities that help to reduce
     the cost of providing utility service.

Q.   WHAT IS THE DURATION OF THESE BENEFITS TO CUSTOMERS?

A.   The customer benefits that are created, i.e., lower costs, improved
     efficiency, and better service, are direct and permanent. Although
     transaction and other "up-front" costs are incurred to achieve these
     customer benefits, the magnitude and permanence of these benefits generally
     produces a value for customers that far outweighs the associated one-time
     costs. As described below, and in the testimony of Mr. Bodanza, Essex
     customers will receive substantial and lasting benefits as a result of
     Eastern's acquisition of Essex.

                                                                   Exhibit WJF-1
                                                                  March 25, 1998
                                                                          Page 4


Q.   WHAT FACTORS PLAYED A ROLE IN EASTERN'S DECISION TO ENGAGE IN THIS
     TRANSACTION?

A.   As competition intensifies and gas utilities fully unbundle at the local
     level, especially in a performance-based regulatory environment, the keys
     to success are increasing gas throughput, improving productivity,
     controlling costs and providing quality customer service. The value of
     Eastern's investment in its gas operations, and in turn our shareholders'
     investment in Eastern, is maintained and potentially enhanced as long as we
     are able to achieve those objectives. Fortunately, New England is
     experiencing above-average growth rates for natural gas. At the same time,
     however, size and scale are critical to achieving the necessary
     productivity and cost efficiencies to support our growth initiatives, as is
     investment in new technology and infrastructure. Utilities, in general, are
     characterized by a high level of fixed costs. Spreading those fixed costs
     over a larger base of customers and/or unit throughput will reduce prices
     and enhance competitiveness.

     The gas utility industry in Massachusetts, including Boston Gas, has made
     substantial strides in cost reduction and productivity improvements as a
     result of their own reengineering and continuous improvement efforts.
     However, the attainment of significant incremental customer savings now has
     to come from consolidation and rationalization of the industry. Such
     efforts are essential in order to remain competitive.

                                                 Testimony of Walter J. Flaherty
                                                                   Exhibit WJF-1
                                                                  March 25, 1998
                                                                          Page 5


     In sum, Eastern believes that utility consolidation provides an opportunity
     to reduce costs, lower prices, enhance service for customers and preserve
     competitiveness. It is a critical and beneficial strategy because it
     represents a win-win situation for customers and shareholders. Eastern's
     acquisition of Essex is a prime example of this strategy.

Q.   WHAT SPECIFIC BENEFITS DOES EASTERN ENVISION WILL RESULT FROM THE PROPOSED
     ACQUISITION OF ESSEX?

A.   Although Essex has a strong reputation, both within the industry and its
     service territory, as a well-managed, financially sound utility providing
     quality service to its customers, its small size presents opportunities for
     economies of scale operating under Eastern's corporate umbrella and as a
     sister company to the contiguous Boston Gas. Essex's gas supply resources
     can be redesigned and re-optimized and its gas supply planning and
     dispatching functions will be augmented by the resources of Boston Gas. As
     a result, customers of both companies will benefit substantially from
     increased supply options and enhanced purchasing power. The ability to
     dispatch across the combined distribution systems will increase dispatch
     flexibility, enable existing gas supply resources to be optimized,
     encourage and facilitate more efficient purchasing decisions, and secure
     the ability to exercise broader system control. The expanded supply
     portfolio will also increase the overall reliability in both service
     territories. The gas supply portfolio synergies are described in detail in
     the testimony of Mr. Luthern. In addition, the merger presents an
     opportunity to realize cost savings as

                                                                   Exhibit WJF-1
                                                                  March 25, 1998
                                                                          Page 6


     a result of reduced O&M expenses, i.e., corporate, administrative and
     operational expenses. These opportunities are discussed in greater detail
     in the testimony of Mr. Bodanza. In short, the acquisition of Essex will
     allow Eastern to capture valuable synergies that exist between the two
     contiguous distribution systems and to transform such efficiency gains into
     cost savings and a more flexible and reliable distribution system for all
     customers.

Q.   HOW WILL ESSEX'S RATES BE AFFECTED?

A.   As described in greater detail in Mr. Bodanza's testimony, Eastern proposes
     that Essex's customers would receive an immediate 5 percent reduction in
     their total burner-tip prices upon consummation of the merger. In addition,
     Essex's base rates would be frozen for a period of ten years, which will
     provide customers with significant price stability and additional savings
     through the avoidance of rate increases that customers would have otherwise
     experienced.

Q.   WHAT IS THE NATURE OF THE INVESTMENT REQUIRED TO ATTAIN THE BENEFITS
     ASSOCIATED WITH THIS ACQUISITION?

A.   As described in the testimony of Messrs. Murphy and Bodanza, the investment
     required to obtain the benefits associated with Eastern's acquisition of
     Essex is represented by three categories of costs: (1) the transaction
     costs incurred in developing, executing and obtaining the necessary
     approvals for the merger; (2) costs incurred to achieve the synergies that
     should ultimately reduce the cost of Essex's operations; and (3) the cost
     to Eastern's shareholders for the

                                                                   Exhibit WJF-1
                                                                  March 25, 1998
                                                                          Page 7


     acquisition, i.e., the premium over book value received by Essex
     shareholders, which will be reflected in the level of earnings dilution
     experienced by Eastern's current shareholders as a result of the exchange
     of Eastern's common stock for the common stock of Essex. In this case, the
     total of all these acquisition costs is estimated to be approximately $61
     million.

Q.   HOW DO THE DEPARTMENT'S REGULATORY POLICIES REGARDING THE RECOVERY OF
     ACQUISITION COSTS AFFECT THE ATTAINMENT OF CUSTOMER BENEFITS ASSOCIATED
     WITH LDC MERGERS AND ACQUISITIONS?

A.   It is generally recognized that mergers and acquisitions have the potential
     to provide significant and lasting benefits to customers. Our proposal will
     achieve this result for Essex's customers. At the same time, substantial
     costs, including the real cost of an acquisition premium, must be incurred
     by the acquiring entity and its shareholders to effect such a transaction.
     Thus, the Department's policy regarding the recovery of such costs will
     heavily influence the achievement of mergers or acquisitions (and their
     corresponding benefits) in this industry. Unregulated industries derive
     profits from the free flow of the competitive market place, and therefore,
     take investment risk with the knowledge that recovery of that investment
     will be a function of their own management and business expertise. The
     utility industry conducts business on the basis of regulated prices that
     reflect regulatory ratemaking policies based on a variety of social,
     political and financial factors. Thus, the ability of regulated utilities
     to recover shareholder investment is often limited by regulatory policies
     that serve broader societal interests.

                                                                   Exhibit WJF-1
                                                                  March 25, 1998
                                                                          Page 8

     Without regulatory recognition that acquisition costs are incurred to
     effect a transaction that will ultimately provide significant cost savings
     and other benefits for customers, shareholders will not put their capital
     at risk to effect such a transaction. In order to achieve the cost savings
     generated by the merger, it is necessary for the Department to recognize
     that there is a direct connection between the benefits realized and the
     investment necessary to generate those benefits. An appropriate regulatory
     policy that aligns customer, company and shareholder interests will
     encourage cost-effective mergers and acquisitions by preserving shareholder
     investment and by making customers the primary beneficiaries of the
     available cost savings. Thus, it is extremely important that the Department
     allow, in some reasonable manner, Eastern shareholders an opportunity to
     recover the investment that was necessary to obtain real and lasting
     benefit for Essex customers.

IV.  DESCRIPTION OF THE ACQUISITION PROCESS

Q.   PLEASE SUMMARIZE THE TERMS OF THE MERGER.

A.   Pursuant to the terms of the Merger Agreement, Eastern will create and
     incorporate Merger Co. as a wholly owned subsidiary. Merger Co. will then
     be merged into Essex, with Essex, as the surviving corporation, continuing
     as a wholly owned subsidiary of Eastern. Each share of Essex common stock
     will then be exchanged for 1.183985 shares of Eastern common stock. The
     Merger Agreement further provides that the actual number of Eastern shares
     exchanged for each Essex share will be adjusted in order to ensure that the
     market value of

                                                 Testimony of Walter J. Flaherty
                                                                   Exhibit WJF-1
                                                                  March 25, 1998
                                                                          Page 9

     the Eastern common stock is not less than $45 per share, nor greater than
     $50 per share, upon conversion.

Q.   PLEASE DISCUSS THE CREATION AND FUNCTION OF MERGER CO.

A.   As mentioned above, Eastern will create Merger Co. as a new wholly owned
     subsidiary to facilitate Eastern's acquisition of Essex. Once the
     transaction is completed, Essex will be an affiliate of Boston Gas and
     Midland. Eastern has agreed to create Merger Co. because it was the express
     desire of Essex's shareholders and Board of Directors that the merger be
     structured as a tax-free transaction. If Eastern structured the acquisition
     either as a cash purchase of Essex's stock or as a merger of Essex directly
     into Boston Gas, the transaction could not have qualified as a tax-free
     reorganization, pursuant to Section 368(a) of the Internal Revenue Code,
     triggering tax liabilities at both the corporate and shareholder levels. By
     utilizing Merger Co. as a merger vehicle, Eastern can ensure that the share
     exchange between Eastern and Essex will not be taxable. The structure also
     avoids the payment of certain debt-related pre-payment penalties and costs
     that would have become payable if Essex were not the surviving entity.

Q.   HOW WILL EASTERN ACCOMPLISH THIS TRANSACTION?

A.   As discussed above, the overall structure of the transaction will result in
     the acquisition of Essex by Eastern. The specific steps that will be taken
     to accomplish this transaction are set forth in the Merger Agreement with
     Essex. In

                                                                   Exhibit WJF-1
                                                                  March 25, 1998
                                                                         Page 10


     accordance with the Merger Agreement, Eastern will create Merger Co., as a
     wholly owned subsidiary of Eastern, and Merger Co. will issue 100 shares of
     common stock to be held by Eastern. Eastern will then merge Merger Co. with
     and into Essex, with each share of Merger Co. being converted into one
     share of the surviving company's common stock. The issued and outstanding
     shares of pre-merger Essex shall be converted into the right to receive
     shares of Eastern common stock, $1.00 par value, based upon the applicable
     conversion rate. As a result, Eastern will be the sole owner of the
     outstanding shares of Essex, as the surviving company, and Eastern will
     have issued approximately $2.1 million additional shares of its own common
     stock to the shareholders of Essex to accomplish the merger.

Q.   WHAT WILL BE THE CORPORATE STATUS OF ESSEX AFTER THE MERGER IS CONSUMMATED?

A.   As a "Section 1 gas company," Essex, the surviving company of the merger,
     will continue to be regulated by the Department pursuant to G.L. c. 164. At
     the same time, Essex will be a wholly owned subsidiary of Eastern, and an
     affiliate of Boston Gas, Midland, ServicEdge and AMR Data.

V.   REGULATORY APPROVALS REQUIRED

Q.   WHAT REGULATORY APPROVALS ARE REQUIRED FOR COMPLETION OF THE MERGER?

A.   There are several regulatory approvals required for consummation of the
     merger, including those of the Securities and Exchange Commission (the
     "SEC") and the Department. In addition to regulatory approvals, Essex's
     shareholder approval of

     the merger is required. A meeting of Essex's shareholders is scheduled for
     May 19, 1998 to vote on the merger.

Q.   WHAT SPECIFIC APPROVALS ARE NEEDED FROM THE SEC?

A.   Pursuant to the Public Utility Holding Company Act of 1935, the SEC must
     approve the acquisition by Eastern of the common stock of Essex, pursuant
     to the Merger Agreement. In addition, pursuant to the Hart-Scott-Rodino
     Antitrust Improvements Act of 1976, the merger is subject to expiration of
     a waiting period (30 days, subject to an extension), during which the
     Federal Trade Commission and the Department of Justice may review any
     antitrust issues that are raised by the merger.

Q.   WHAT ARE THE SPECIFIC APPROVALS REQUESTED OF THE DEPARTMENT?

A.   Eastern seeks the following approvals and determinations from the
     Department:

     (1)  Approval of the merger between Merger Co. and Essex, as provided for
          by the terms of the Merger Agreement, consistent with the public
          interest pursuant to G.L. c. 164, ss. 96;

     (2)  Approval of the issuance of 100 shares of common stock, par value of
          $1.00, by Merger Co. to Eastern pursuant to G.L. c. 164, ss. 14;

     (3)  Approval of Essex's proposed rate plan, pursuant to G.L. c. 164, ss.
          94; and

     (4)  A determination that no transfer of Essex's franchise will occur as a
          result of the merger and related transactions. Pursuant to G.L. c.
          164, ss. 21, approval of the Massachusetts General Court would be
          required in the

          event that the structure of the merger required a transfer of Essex's
          franchise to Merger Co. (or some other third party).

Q.   DOES THIS CONCLUDE YOUR TESTIMONY?

A.   Yes, it does.

II.  THE DECISION TO SELL ESSEX TO EASTERN

Q.   PLEASE PROVIDE A BRIEF DESCRIPTION OF ESSEX COUNTY GAS COMPANY.

A.   Essex is a local gas distribution company ("LDC"), regulated by the
     Department of Telecommunications and Energy (the "Department") as a "gas
     company," pursuant to G.L. c. 164, ss. 1. Essex was organized in 1853 under
     the laws of the Commonwealth of Massachusetts and currently operates in the
     cities of Haverhill, Newburyport and Amesbury, as well as 14 other
     municipalities covering an area of approximately 280 square miles. Essex's
     service area is primarily composed of residential communities with a number
     of small commercial and diversified light industrial businesses. Essex
     sells natural gas to approximately 42,000 customers in its service area.

Q.   PLEASE EXPLAIN WHY ESSEX DECIDED TO PURSUE A MERGER AT THIS TIME?

A.   Over the past several years, Essex's Board of Directors (the "Board") and
     the management of Essex have followed developments in the gas utility
     industry closely with a particular focus on changes in regulatory policies.
     As industry restructuring initiatives have been developed and implemented,
     Essex has carefully considered the impact of such initiatives on Essex's
     business strategy options going forward. With the unbundling of LDC
     services, the implementation of customer choice programs, the transfer of
     the gas supply merchant function to unregulated marketers and the business
     operating restrictions that result from application of the Department's
     standards of conduct, it has become increasingly clear to Essex that its
     relatively small size and limited access to available

                                                  Testimony of James H. Hastings
                                                                   Exhibit JHH-1
                                                                  March 25, 1998
                                                                          Page 3


     resources would restrict its business opportunities to being a local
     distributor of natural gas. As Essex formulated its business plan, it
     became evident that the opportunities to improve the efficiency of its
     operations by leveraging its resources into other business activities were
     severely constrained. Further analysis of its existing resources indicated
     that the ability to attain savings through the creation of economies of
     scale and/or scope would be far greater with more expansive operations than
     the savings Essex could achieve on its own. As a result of this analysis,
     the Board, in conjunction with Essex management, concluded that it should
     further investigate the benefits that could potentially result from a
     business combination with a larger utility operating company to determine
     if such a strategy would be in the overall best interest of the Company's
     customers and shareholders.

III. OVERVIEW OF PROCESS TO EFFECT MERGER

Q.   WHAT PROCESS DID ESSEX USE TO MAXIMIZE THE VALUE ATTAINED FOR THE COMPANY?

A.   In order to obtain a fair, market-based price for the sale of the Company,
     Essex engaged the services of an experienced and independent financial
     advisor to conduct a competitive bidding process with the objective of
     maximizing the benefits provided to Essex customers and shareholders as a
     result of the sale. Specifically, at a Board meeting on July 21, 1997, the
     Board authorized management to interview and select investment bankers for
     the purpose of achieving the Board's objectives in this process. On
     September 15, 1997, Essex

                                                                  March 25, 1998

     retained Furman Selz, L.L.C. ("Furman Selz"), an investment banking
     company, to serve as financial advisor to the Company in connection with a
     possible business combination with a third party. Furman Selz contacted
     more than 35 companies to solicit their interest in a transaction involving
     the acquisition of Essex. Of that group, 13 companies agreed to sign a
     confidentiality agreement and were sent a descriptive memorandum with
     respect to Essex. Six of those companies submitted non-binding indications
     of interest at the end of October and the first week of November. Based on
     such indications, five of the companies, including Eastern, were invited to
     conduct additional due diligence during the middle two weeks of November
     and to submit proposals no later than December 5th.

Q.   HOW WAS THE BIDDING PROCESS STRUCTURED?

A.   On behalf of Essex, Furman Selz invited the five potential bidders to
     submit proposals no later than December 5th and requested that the bidders
     communicate comments on a proposed merger agreement included in the
     solicitation. In soliciting those bids, Furman Selz indicated the Board's
     preference for a stock-for-stock transaction in which shareholders could
     exchange their shares on a tax-free basis, although the Board was willing
     to entertain cash bids as well. All five of the bidders submitted proposals
     on December 5th.

                                                                   Exhibit JHH-1
                                                                  March 25, 1998
                                                                          Page 5

Q.   HOW DID ESSEX DETERMINE THAT EASTERN'S PROPOSAL REPRESENTED THE MAXIMUM
     VALUE ACHIEVABLE FOR ESSEX CUSTOMERS AND SHAREHOLDERS?

A.   After reviewing all of the proposals with Essex management, Furman Selz
     conducted negotiations with the five final bidders. Those direct
     negotiations resulted in Eastern making the proposal that is embodied in
     the Merger Agreement. Of particular significance to Essex was the fact that
     Eastern's subsidiary, Boston Gas, operates in a service territory that is
     contiguous to that of Essex, which creates a significant potential for both
     companies to achieve operational synergies and associated cost reductions.
     In recognition of this potential, the proposed Rate Plan, as described in
     the testimony of Mr. Bodanza, provides an immediate 5 percent reduction in
     the current overall burner-tip price of gas to Essex customers. In
     addition, under the Rate Plan, Essex customers will receive significant
     benefits in the form of a freeze in base rates for the next 10 years. This
     base rate freeze will preclude the filing of three base rate cases. In sum,
     because Eastern's proposal was structured as a tax-free stock exchange and
     because it offered Essex's customers and shareholders the best possible
     overall financial benefits compared to those of all other bidders, the
     Board and Essex management selected Eastern as the winning bidder.

Q.   WHAT IS THE PROPOSAL THAT IS EMBODIED IN THE MERGER AGREEMENT?

A.   As discussed in the testimony of Walter J. Flaherty, the terms of the
     Merger Agreement provide that one share of Essex common stock will be
     exchanged for 1.183985 shares of Eastern common stock. The actual number of
     Eastern shares

                                                                  March 25, 1998
                                                                          Page 6


     to be issued will be adjusted to ensure that the value of Eastern common
     stock to be issued for each Essex share will not be less that $45.00 nor
     more than $50.00, based upon the average market price during a specified
     period prior to closing. Structured in this manner, the transaction is free
     of tax at the corporate level, as well as the shareholder level.

IV.  BENEFITS OF THE MERGER TO ESSEX CUSTOMERS

Q.   PLEASE DESCRIBE THE BENEFITS OF THE MERGER TO ESSEX'S CUSTOMERS.

A.   Over the past several years, Essex has worked diligently to reduce its
     operations and maintenance expenses and gas costs associated with serving
     its customer base. The proposed transaction offers the potential for
     additional savings that would not be achievable in the absence of Eastern's
     acquisition of Essex. In particular, there is the potential to attain
     savings as a result of the coordination of similar functions that are
     typically performed by both companies. In accordance with the Rate Plan,
     discussed in Mr. Bodanza's testimony, Essex's customers will experience
     significant savings immediately upon the approval of the acquisition.

     Specifically, the Rate Plan provides for an immediate 5 percent reduction
     in the burner-tip prices paid by Essex customers. As mentioned above, these
     savings are made possible as a direct result of the acquisition because of
     the ability to capture potential gas cost savings through the coordination
     of the gas planning, acquisition and dispatch activities of Essex and
     Boston Gas, as well as other cost savings attainable through integration
     and coordination of certain administrative and operating functions of the
     two companies.

                                                                   Exhibit JHH-1
                                                                  March 25, 1998
                                                                          Page 7


Q.   HOW WILL THESE SAVINGS BE PASSED ON TO ESSEX'S CUSTOMERS?

A.   Essex's customers will obtain the savings associated with the Rate Plan
     through reductions in gas costs, which will be reflected in Essex's Cost of
     Gas Adjustment factor and the Local Distribution Adjustment Clause. In
     addition, as part of the Rate Plan, no increase in base rates will be
     sought for a period of 10 years.

Q.   WOULD IT BE POSSIBLE TO ACHIEVE THESE SAVINGS IN THE ABSENCE OF THE
     ACQUISITION OF ESSEX BY EASTERN?

A.   As I have indicated, Essex has been, and continues to be, dedicated to
     reducing its costs in all areas in order to provide its customers with
     reliable gas sales and transportation services at the lowest possible cost.
     However, there are limitations on Essex's ability to capture the high level
     of savings that could potentially be achieved through a merger with a
     larger entity, especially where Boston Gas' service territory is contiguous
     with Essex's service territory. As described in Mr. Bodanza's testimony,
     the acquisition will create economies of scale and synergies that present
     the opportunity for significant cost reductions and ultimately short and
     long-term benefits to customers in the form of lower prices.

V.   ENDORSEMENT OF THE RATE PLAN

Q.   DO YOU BELIEVE THAT THE BENEFITS PROVIDED BY THE RATE PLAN ARE IN THE BEST
     INTEREST OF ESSEX'S CUSTOMERS?

A.   Yes, I do. The Rate Plan, an integral part of the merger, will provide
     immediate and substantial rate relief to Essex's customers. Those benefits
     will continue to grow significantly over the next 10 years and beyond. As I
     explained above, the benefits provided to Essex's customers would not be
     available without the

                                                                   Exhibit JHH-1
                                                                  March 25, 1998
                                                                          Page 8


     acquisition of Essex by Eastern. Thus, I believe, the Rate Plan is clearly
     in the best interest of all Essex customers.

Q.   WHAT AFFECT WOULD A FAILURE TO APPROVE THE ACQUISITION AND THE ASSOCIATED
     RATE PLAN HAVE ON ESSEX'S CUSTOMERS?

A.   Were the acquisition and the associated Rate Plan not to receive approval,
     Essex's customers would not obtain the immediate 5 percent price reduction
     that would otherwise take effect upon approval of the merger. In addition,
     Essex's customers would lose the benefit of the guarantee of rate
     stability, i.e., that current rates would remain in effect for a period of
     10 years. In lieu of the Department's approval of the proposed transaction,
     Essex would likely be put in the position of seeking a rate increase in
     1999. Accordingly, the failure to approve the merger and the associated
     Rate Plan would have significant adverse effects on Essex's customers. I
     believe that, given the potential cost savings and the fact that such
     savings would not otherwise be achievable absent the proposed transaction,
     approval of the acquisition and the associated Rate Plan is consistent with
     the public interest pursuant to G.L. c. 164,ss. 96.

Q.   DOES THIS CONCLUDE YOUR TESTIMONY?

A.   Yes, it does.

Q.   WHAT IS THE PURPOSE OF YOUR TESTIMONY?

A.   The purpose of my testimony is: (i) to describe the recent history of
     mergers in the natural gas industry and to demonstrate that the price paid
     by Eastern for Essex is reasonable and consistent with this experience; and
     (ii) to explain the principle of pooling of interests accounting and
     earnings dilution and to discuss the application of these principles to the
     Eastern acquisition of Essex.

II.  RECENT HISTORY OF MERGERS AND ACQUISITIONS IN THE GAS UTILITY SECTOR

Q.   PLEASE PROVIDE A BRIEF OVERVIEW OF THE RECENT HISTORY OF MERGERS AND
     ACQUISITIONS IN THE GAS UTILITY INDUSTRY.

A.   Historically, there has been limited merger and acquisition ("M&A")
     activity in the gas utility industry.(1) During the five-year period from
     1990 to 1994, there were eleven M&A transactions in this sector with a
     total value of approximately $1.8 billion. More recently however, with the
     introduction of deregulation and competitive forces, M&A activity in the
     gas utility sector has increased. Since the beginning of 1995, there have
     been fourteen completed transactions representing a total of $16.3 billion.

     Most of these transactions represented industry consolidation (gas utility
     to gas utility mergers and acquisitions) and energy convergence (primarily
     gas and electric utility combinations). Salomon Smith Barney anticipates a
     continued

                                                                          Page 4


     high level of transactions as deregulation and competitive forces are
     introduced across the nation over the next five years.

Q.   WHAT FACTORS HAVE LED TO THE INCREASED LEVELS OF MERGER AND ACQUISITION
     ACTIVITY IN THE GAS UTILITY SECTOR IN RECENT YEARS?

A.   As noted above, the increased level of M&A activity is largely driven by
     the forces of existing and future competition in the energy industry. Gas
     and electric utility deregulation introduces customer choice and
     competition. These forces require traditional cost-of-service utilities to
     position for a new market order where low operating costs, efficiencies,
     economies of scale and superior customer service are the keys to both
     survival and, ultimately, success. To remain competitive in this market
     environment, companies will need to develop both large scale and low-cost
     structures. Larger scale will be required to develop the physical plant and
     technical infrastructure to compete. Low-cost structures will be needed to
     offer services at prices customers will find attractive. Mergers and
     acquisitions are a primary means to achieve these goals. Companies that
     combine can reduce their operating and maintenance expenses by eliminating
     overlapping or redundant functions (i.e., "cost synergies") in such ----
     areas as managerial and supervisory positions; legal, accounting and
     consulting services; customer accounting, billing, collection and other
     "back office" operations; planning, contracting and administrative
     services, and field service and operations.

Q.   WHAT HAS BEEN YOUR PARTICULAR EXPERIENCE WITH SUCH MERGERS AND ACQUISITIONS
     IN THE GAS UTILITY SECTOR OVER THE PAST SEVEN YEARS?

A.   During the past seven years, I have advised on eleven completed
     transactions and restructurings in the gas distribution and transmission
     industry valued at over $11.5 billion. These transactions are listed in
     Exhibit PJM-2, attached. The number of transactions I have worked on in
     this area has increased over the last several years.

Q.   IN GENERAL, HOW ARE UTILITY ACQUISITIONS STRUCTURED?

A.   Deals have been structured as stock or cash acquisitions, in which the
     acquiring company has paid a premium to the selling company or its
     shareholders, as the case may be. Attached is Exhibit PJM-3, which lists
     some recent acquisitions and the particular characteristics of those
     transactions.

Q.   IN GENERAL, HOW HAVE THE ACQUISITION PRICES OF THESE TRANSACTIONS COMPARED
     TO THE BOOK VALUES OF THE ACQUIRED COMPANIES AND WHAT IS THE REASON FOR ANY
     DISPARITY?

A.   In each of the utility transactions, the price paid by the acquiring
     company has been at a premium to the book value of the acquired company.
     The magnitude of the premiums, as noted on the list of precedent
     transactions, has ranged from 1.4x to 3.5x the seller's book value. This
     range of premiums has generally narrowed to 1.9x to 2.8x over the past
     three years. Buyers generally pay a premium to the seller's book value in
     these transactions because of the cost savings and economies that they can
     achieve and retain for shareholders to offset their costs incurred in
     achieving the merger.

     Market-to-book value multiples paid to acquire gas utilities can and do
     vary quite broadly for very good reasons. Generally speaking, an acquiror
     is willing to pay a price for a target company consistent with expected
     earnings growth or increased stock values, which are deemed acceptable by
     the acquiror's management and board of directors. The price paid, as a
     multiple of book value, reflects the buyer's expectations of the acquired
     company's future contribution to the combined company's short- and
     long-term financial performance. These expectations are driven primarily by
     multi-year projections of cost savings and rate treatment, as well as the
     nature of the currency used to pay for the acquisition. The financial
     impact of these factors can vary quite broadly from case to case, which is
     reflected in the range of market-to-book values paid or proposed for gas
     utility acquisitions in recent years.

Q.   IN GENERAL, HOW HAVE THE ACQUISITION PRICES OF THESE MERGERS COMPARED TO
     THE EARNINGS OF THE ACQUIRED COMPANIES?

A.   As illustrated by the precedent transactions listed in Exhibit PJM-3,
     buyers of utility companies have been paying approximately 15 to 35 times
     the preceding twelve month earnings, with a median price of slightly over
     20 times the twelve month earnings. As was the case with the premium prices
     paid relative to book value, such high price-to-earnings multiples are
     justified only where there are sound expectations that cost savings and
     economies will be realized and retained for the benefit of shareholders.

Q.   GIVEN YOUR EXPERIENCE WITH OTHER GAS UTILITY MERGERS AND ACQUISITIONS AND
     YOUR SPECIALIZED KNOWLEDGE OF THE INDUSTRY, IS IT YOUR OPINION THAT THE
     PURCHASE PRICE PAID BY EASTERN FOR ESSEX IS REASONABLE?

A.   Yes. As advisor to Eastern, Salomon Smith Barney carefully analyzed the
     price paid in the acquisition and considered it both in relation to the
     prices paid in similar relevant transactions and management's estimates of
     the cost savings that may be achieved through the transaction. Salomon
     Smith Barney concluded that the purchase price to be paid by Eastern for
     Essex is reasonable (and so reported to both management and the Board of
     Directors). One of the important factors leading to Salomon Smith Barney's
     opinion on the reasonableness of the transaction price was the value paid
     by Eastern as a multiple of Essex's earnings and book value. In that
     regard, the purchase price to be paid by Eastern represents 2.3 times
     Essex's book value and 18.6 times Essex's latest twelve-month earnings.
     These multiples are consistent with recent comparable gas distribution
     acquisitions (see Exhibit PJM-3). 

III. THE PRINCIPLE OF POOLING OF INTEREST ACCOUNTING AND EARNINGS DILUTION

Q.   PLEASE DESCRIBE THE ALTERNATIVE METHODS OF ACCOUNTING FOR AN ACQUISITION.

A.   Acquisitions are reflected in one of two ways under generally accepted
     accounting principles: purchase accounting and pooling of interests
     accounting. In a purchase accounting transaction (where one company
     purchases the assets or stock of another), any amount paid for the acquired
     company in excess of book value, i.e., a premium or "goodwill," is recorded
     on the books of the acquired

<PAGE>   35
                                                     Testimony of Paul J. Murphy
                                                                   Exhibit PJM-1
                                                                  March 25, 1998
                                                                          Page 8


     company as an adjustment to the value of the company's asset or
     capitalization accounts and amortized over a period of time. The
     amortization of the acquisition premium represents an expense and, if not
     recovered, results in lower earnings for shareholders.

     Pooling of interests accounting is required if the transaction involves the
     exchange of common stock and certain other criteria are met. As discussed
     in Mr. Flaherty's testimony, Eastern's acquisition of Essex will be
     structured as a pooling of interests transaction. Under pooling of interest
     accounting, an acquisition is effected through an exchange of the voting
     stock of the acquiror for all, or a substantial portion of, the voting
     stock of the acquiree. The balance sheets of the acquiror and the acquiree
     are simply combined, and for accounting purposes, there is no adjustment
     (i.e., increase or decrease) to any of the assets or liabilities of the
     merged entities to account for the acquisition premium. Rather, the
     exchange ratio, in this case one Essex share exchanged for 1.183985 Eastern
     shares, reflects a number of factors, such as a premium for management
     control of the company and the long term strategic and economic value to be
     gained through the acquisition. Thus, pooling accounting results in a
     merger of previously independent stockholder interests into a new
     consolidated entity and, although shareholders of the acquired company may
     receive a premium, there is no associated adjustment to the book value of
     the assets of the new entity, as is the case in a purchase accounting
     transaction.

Q.   HOW DOES POOLING OF INTERESTS ACCOUNTING AFFECT THE EARNINGS OF THE
     ACQUIRING COMPANY?

A.   In a typical pooling of interests acquisition, the acquiring company pays a
     premium price for the utility being acquired. This premium price is
     reflected in valuation measures (i.e., market to book value and price
     earnings multiple) of the acquired utility. Since common equity is the
     currency used to effect the combination, the payment of shares at such a
     premium price results in a pro forma dilution of both the book value and
     earnings per share of the acquiror. The payment of the premium to acquire
     the target, and the subsequent risk of dilution, are rational undertakings
     only where management believes that the retention of financial benefits
     derived from the merger will more than offset the costs of the transaction.

     Since mergers and acquisitions are undertaken to enhance shareholder value,
     rather than to diminish it, earnings dilution must be considered by Eastern
     in consummating this transaction. Eastern's shareholders have the
     reasonable expectation that the economic benefits of the transaction will
     be shared with customers in a manner that will augment Eastern's earnings
     and enhance the value of its shares.

     This pooling of interests process and its dilutive impact on earnings is
     demonstrated by the following hypothetical acquisition of Utility B by
     Utility A.

     Table 1 represents the pre-acquisition characteristics of Utility A and
     Utility B, indicating the difference in size between the two as well as the
     identical per share features for both.

     Utility B is then acquired by Utility A through the exchange of stock at a

     Utility A shareholders.

     As demonstrated in Table 2, the premium paid in stock by Utility A to
     acquire Utility B results in pro forma dilution of both book value and
     earnings per share for Utility A shareholders.

Q.   WHAT DOES THE EARNINGS DILUTION EXPERIENCED BY THE ACQUIRING COMPANY'S
     SHAREHOLDERS REPRESENT?

A.   In purchase accounting, an adjustment (i.e., an increase or decrease), is
     made to the asset or capitalization accounts of the acquired company to
     reflect the "acquisition premium" or the amount paid by the acquiror in
     excess of book value. Under pooling of interests accounting, an
     "acquisition adjustment" is not explicitly recorded on the books in this
     manner. Rather, the acquisition premium is reflected in the difference
     between the valuation of the stock of the acquiring company and the value
     of the stock of the acquired company, which is exchanged in order to
     accomplish the transaction. Although the accounting treatment may be

                                                                         Page 12


     different, the result is the same. That is, the acquisition premium, or the
     amount of earnings dilution to be experienced by the acquiring company's
     shareholders, represents a real economic cost incurred to execute the
     transaction.

Q.   WILL EASTERN'S SHAREHOLDERS EXPERIENCE EARNINGS DILUTION AS A RESULT OF THE
     ACQUISITION OF ESSEX?

A.   Yes, similar to the example described above, Eastern will issue additional
     shares of its common stock to execute the transaction. Those additional
     shares will be exchanged for shares of Essex at a rate of 1.183985 shares
     of Eastern for each share of Essex. As demonstrated in the table below,
     which was based on financial information available at the time of the
     offer, this premium valuation for Essex would result in a pro forma
     dilution of both book value and earnings for Eastern's shareholders.

     This dilution of earnings represents a real cost to Eastern's shareholders.
     Moreover, this pro forma analysis does not include the out-of-pocket
     transaction and synergy costs of approximately $15 million, which are
     identified in Mr. Bodanza's testimony, that will also be financed and borne
     by Eastern's shareholders. If unable to retain a portion of the cost
     savings resulting from the merger, Eastern's shareholders will suffer both
     book value and earnings dilution in the value of their holdings. Unless
     there is a reasonable opportunity to recover the premium associated with
     this type of transaction through the retention of a portion of the attained
     synergies, mergers of this sort cannot be accomplished. Mergers are
     undertaken to enhance shareholder value, not reduce it. As a result,

     shareholders' reasonable expectations are that the economic benefits of
     this merger will be shared with customers in a way that will enhance,
     rather than diminish, the amount of Eastern's earnings and the value of its
     shares. Absent a reasonable opportunity for the recovery of and return on
     investor costs, investor earnings will be reduced.

Q.   CAN THE MINIMUM ECONOMIC BENEFIT EASTERN SHAREHOLDERS ARE EXPECTING TO
     RECEIVE BE CALCULATED?

A.   Yes, it can. To avoid dilution to Eastern's earnings and a reduction in the
     value of Eastern's shares, shareholders would need incremental economic
     benefit from the Essex merger of at least $46 million in pre-tax earnings
     over the next ten years (see Exhibit PJM-4) (not including the
     out-of-pocket transaction costs of $15 million identified in Mr. Bodanza's
     testimony). This calculation is based on several assumptions. Utilizing
     Eastern's 1998 estimated average earnings per share from First Call,(1) I
     projected earnings assuming growth at a conservative three percent annual
     rate over the next 10 years. This growth rate is conservative in light of
     both Eastern's historical performance and its corporate objectives.
     Moreover, this three percent growth rate is conservative relative to
     typical gas utility growth rates. It is important to note that, as growth
     rates assumed for the

     maintains equity research analysts' estimates of publicly traded companies'
     future earnings and earnings growth rates.

     acquiror increase, the level of earnings dilution it experiences as a
     result of an acquisition also increases. In assuming a highly conservative
     level of growth, the level of earnings dilution may be understated.

     The dilutive impact of the merger with Essex was calculated based on the
     Essex five-year stand-alone financial plan, which were provided to Eastern
     and other potential acquirors in due diligence prior to the announcement of
     the acquisition. For 2000 and beyond, Eastern management projected that
     Essex could maintain annual net income of $4 million. Using this assumption
     and pooling accounting, the combination of Eastern and Essex results in
     pre-tax earnings dilution to Eastern's shareholders of an average of $4.6
     million per year, or $0.12 per share. This represents a real economic loss
     to Eastern's shareholders of roughly 2.8 percent of the earnings, in 1998,
     that Eastern would otherwise have expected to earn had the acquisition not
     occurred (see Exhibit PJM-4). This loss grows to as much as 4.5 percent in
     the tenth year.

     As noted earlier, earnings dilution is a real economic loss to Eastern's
     shareholders which they would reasonably expect to recover through the cost
     savings and synergies achieved through the combination of the two
     companies. Not counting the $15 million in acquisition-related expenses
     computed by Mr. Bodanza, the analysis in Exhibit PJM-4 illustrates that
     Eastern needs to retain over a ten-year period an average of $4.6 million
     of savings per year simply to recover from the expected impact of dilution.
     Acquirors generally expect to do

     better than this in return for both putting their capital at risk and
     undertaking the considerable effort required to achieve benefits for both
     customers and shareholders. Acquirors generally expect transactions to
     generate earnings growth to compensate them for these risks and
     expenditures.

Q.   HOW DOES THE EARNINGS DILUTION AND AMOUNT OF COST SAVINGS AND SYNERGIES
     THAT NEED TO BE RETAINED COMPARE IN A POOLING VERSUS A PURCHASE
     TRANSACTION?

A.   If Eastern had acquired Essex in a purchase transaction, the projected
     earnings dilution and synergies required to break even would have been
     significantly greater. This would have resulted in fewer benefits to be
     shared by Essex customers and Eastern shareholders.

     As noted in Mr. Bodanza's testimony, the premium over Essex's book value
     paid by Eastern amounted to $47.1 million. In a traditional rate of return
     context, this premium would be added to Essex's rate base so that the costs
     associated with the premium would be recovered through Essex's future
     rates. As further noted in Mr. Bodanza's testimony, the revenue requirement
     associated with this recovery amounts to an average of $8 million per year
     over a ten-year projected period. This is significantly greater than the
     $4.6 million revenue requirement that shareholders need to "break even" in
     the pooling case discussed above. As a result, pooling treatment is clearly
     the more economical way of completing the acquisition and the alternative
     that leaves the greatest amount of savings available for sharing between
     Eastern's shareholders and Essex's customers. Pooling

                                                                   Exhibit PJM-1
                                                                  March 25, 1998

     achieves this result because Eastern's stock, which is the acquisition
     currency, is itself valued at a premium to its book value in the public
     equity market. This premium helps offset the premium paid to Essex's
     shareholders in the acquisition.

Q.   DOES THIS CONCLUDE YOUR TESTIMONY?

A.   Yes, it does.

                  EASTERN ENTERPRISES/ESSEX COUNTY GAS COMPANY

                         Testimony of Joseph F. Bodanza

                                 D.T.E. 98-____


I.   INTRODUCTION

Q.   PLEASE STATE YOUR NAME AND BUSINESS ADDRESS.

A.   My name is Joseph F. Bodanza. My business address is One Beacon Street,
     Boston, Massachusetts 02108.

Q.   BY WHOM ARE YOU EMPLOYED AND IN WHAT CAPACITY?

A.   I am Senior Vice President and Treasurer of Boston Gas Company ("Boston
     Gas"). I am responsible for the financial, accounting, treasury,
     governmental/state regulatory and public affairs, pricing and rates, as
     well as the design, implementation and maintenance of information and
     communications systems.

Q.   ARE YOU FAMILIAR WITH THE PROPOSED ACQUISITION OF ESSEX COUNTY GAS COMPANY
     BY EASTERN ENTERPRISES?

A.   Yes. Eastern Enterprises ("Eastern") has requested that I evaluate and
     analyze the operations of Essex County Gas Company ("Essex"). In that
     regard, I have attempted to determine if there are synergistic
     opportunities to realize reductions in the operating costs of Essex by
     eliminating or combining certain of its operations with those of Boston
     Gas, thereby reducing the overall level of expenses associated with Essex's
     operations. Based on this analysis, I have been asked to develop a rate
     plan (the "Rate Plan") for Essex.

                                                                  March 25, 1998
                                                                         Page 2


Q.   WHAT IS THE PURPOSE OF YOUR TESTIMONY?

A.   The purpose of my testimony is: (i) to discuss the Rate Plan for Essex; and
     (ii) to review the specific benefits associated with the proposed merger
     demonstrating that the merger is consistent with the public interest,
     pursuant to G.L. c. 164, ss. 96.

II.  DISCUSSION OF THE RATE PLAN

Q.   What is the purpose of the Rate Plan?

A.   The purpose of the Rate Plan is to allocate the potential savings resulting
     from operating synergies in an equitable manner so as to provide Essex
     customers with significant and immediate benefits while allowing Eastern's
     shareholders to recover over a reasonable period of time the costs incurred
     to achieve the merger. In that regard, the Rate Plan provides an immediate
     5 percent reduction in the total burner-tip price of gas currently paid by
     Essex sales customers. In addition, we have proposed to freeze base rates
     for ten years, which will provide customers with price stability and
     additional savings through the avoidance of rate increases that customers
     would have otherwise experienced. Under our proposal, Eastern shareholders
     also have a reasonable opportunity to recover the costs incurred to
     accomplish the merger.

Q.   WHAT ARE THE BASIC ELEMENTS OF THE RATE PLAN THAT YOU ARE PROPOSING?

A.   In developing the proposed Rate Plan, we have set an objective of providing
     an immediate 5 percent reduction in the total burner-tip price of gas
     currently paid by Essex customers. Based on Essex's total normalized
     revenues of approximately

                                                  Testimony of Joseph F. Bodanza
                                                                   Exhibit JFB-1
                                                                  March 25, 1998
                                                                          Page 3


     $46.9 million (pursuant to Essex's 1996 rate settlement and its 1997 CGAC
     filings), the total price reduction will be approximately $2.35 million. As
     described in the testimony of Mr. Luthern, we have identified net cost
     savings for Essex customers of approximately $1.46 million in the first
     year that will result from the attainment of synergies and efficiencies in
     the gas supply function. Savings related to the gas supply function will be
     reflected in Essex's Cost of Gas Adjustment Clause ("CGAC") over the
     ten-year period of the Rate Plan. To achieve an overall $2.35 million rate
     reduction, a credit of $900,000 will be applied to Essex's Local
     Distribution Adjustment Clause ("LDAC") until November 2000. Upon
     expiration of the existing long-haul contract with Tennessee Gas Pipeline
     Company ("Tennessee") in November 2000, total gas savings will increase by
     an additional $900,000.

     In addition, we propose to freeze Essex's base rates for ten years, which
     will provide customers with additional savings of approximately $33
     million. We have estimated that the combined impact of the rate freeze and
     price reductions will provide Essex customers with a benefit of
     approximately $57 million over the next ten years (Exhibit JFB-2).

Q.   ON WHAT BASIS HAVE YOU DETERMINED THAT COST SAVINGS OF APPROXIMATELY $1.46
     MILLION WILL BE ATTAINED AS A RESULT OF SYNERGIES IN GAS SUPPLY OPERATIONS?

A.   We estimate that gas cost savings will be attained as a result of the
     ability to coordinate the gas supply resources of Boston Gas and Essex.
     Such joint

     planning will create increased supply options, result in the more efficient
     use of existing resources, and generate savings from an enhancement of
     Essex's purchasing power. Mr. Luthern has reviewed Essex's gas resource
     portfolio and gas supply operations to identify available synergies, and
     his testimony outlines how these savings will be achieved.

     As indicated by Mr. Luthern, a review of Essex's supply contracts and
     requirements forecast has enabled him to project that gas costs for the
     Essex portfolio will be reduced in the first full year of the merger by
     $2.5 million. That number will increase to $3.4 million upon the expiration
     of the Tennessee long-haul contract on November 1, 2000. The majority of
     these savings ($2.2 million in the first year) will be achieved through the
     release of the Tennessee pipeline capacity and eventually removing the
     total costs of that capacity from the Essex CGAC upon the expiration date
     of the existing contract. The remaining savings of $300,000 per year will
     reflect reduced commodity costs resulting from enhanced purchasing power.
     In addition, there are likely to be opportunities for additional savings
     relating to the restructuring of other capacity contracts in the future.

Q.   IF THE TOTAL SAVINGS WILL BE $2.5 MILLION IN THE FIRST YEAR, WHY WILL ESSEX
     CUSTOMERS RECEIVE ONLY A $1.46 MILLION REDUCTION IN THE CGAC?

A.   To achieve the synergies and resulting capacity cost savings through
     coordination of the Essex and Boston Gas supply portfolios, Boston Gas will
     need to forego

                                                                   Exhibit JFB-1
                                                                  March 25, 1998
                                                                          Page 5


     some opportunity sales, e.g., short-term capacity release revenues. These
     revenues are credited to Boston Gas' customers through the Boston Gas CGAC.
     To compensate Boston Gas' customers for such foregone opportunities, the
     Rate Plan includes a transfer from the Essex CGAC to the Boston Gas CGAC to
     represent a charge to Essex for the value of the Boston Gas resources that
     will be used to serve Essex customers. As described by Mr. Luthern, each
     year an appropriate transfer will be computed. In the first year, that
     transfer will be $1.04 million so that the net savings to Essex' customers
     in the CGAC will be approximately $1.46 million. This adjustment ensures
     that the net savings relating to gas cost synergies are passed through to
     Essex' customers and that Boston Gas' customers are compensated for any
     foregone opportunities.

Q.   HOW DID YOU CALCULATE THE CUSTOMER SAVINGS THAT RESULT FROM THE TEN-YEAR
     FREEZE IN THE BASE RATES OF ESSEX?

A.   To estimate the customer savings resulting from the proposed ten-year rate
     freeze, I have reviewed Essex's five-year financial forecast and historical
     ratemaking patterns and extrapolated from that data. I estimate that, if
     base rates are frozen for ten years, Essex customers will avoid several
     rate cases which, based on Essex's recent history, would have resulted in
     increases of approximately 4 percent every three years on average. Thus, as
     demonstrated in Exhibit JFB-3, over a ten-year period, price increases
     generating approximately $33 million would be avoided.

                                                                  March 25, 1998
                                                                          Page 6


Q.   PLEASE ELABORATE ON THE BASIS FOR THIS ESTIMATE.

A.   Within the past ten years, the Department has approved four base rate
     increases for Essex representing an average increase of approximately 4
     percent. Essex County Gas Company, D.P.U. 96-70 (1996) (approving an
     increase of $2.1 million or 4.6 percent overall); Essex County Gas Company,
     D.P.U. 93-107 (1993) (approving an increase of $1.7 million or 4.2 percent
     overall); Essex County Gas Company, D.P.U. 89-107 (1989) (approving an
     increase of $1.3 million or 4.0 percent overall); Essex County Gas Company,
     D.P.U. 87-59 (1987) (approving an increase $1.2 million or 3.7 percent
     overall). Essex's financial forecast projects that Essex would seek and be
     granted a base rate increase by the Department within the next two years of
     approximately $1.8 million and two increases of a slightly higher level
     later in the ten-year period. Using these assumptions, the ten-year
     base-rate freeze would save Essex customers approximately $33 million (see
     Exhibit JFB-3). Although Essex has been working hard to reduce its
     operations and maintenance ("O&M") and gas supply costs, inflation remains
     a critical factor in Essex's cost structure. That is, Essex's expenses,
     particularly those associated with labor, tend to grow at or above the rate
     of inflation, while its revenues tend to grow at a slightly slower rate.
     Thus, even when inflation is at a relatively low level, as is currently the
     case, Essex has been forced to pursue base rate increases every few years
     to address the disparity between costs and revenues.

                                                                   Exhibit JFB-1
                                                                  March 25, 1998
                                                                          Page 7


     As a result of the Rate Plan, however, the base rates for Essex customers
     would not increase for ten years notwithstanding inflationary pressures.
     The freeze in base rates will be subject only to cost changes resulting
     from exogenous factors such as changes in tax laws, accounting changes and
     regulatory, judicial or legislative changes. Absent recognition of
     exogenous cost changes, the applicability of Statement of Financial
     Accounting Standards No. 71 ("SFAS 71") would be jeopardized for Essex.
     Failure to meet the criteria of SFAS 71 would have an immediate negative
     impact on Essex's financial statements and its ability to finance needed
     investments to ensure the safe and reliable operation of its distribution
     system.


Q.   IF THE 5 PERCENT BURNER-TIP PRICE REDUCTION IS PROVIDED TO ESSEX CUSTOMERS,
     IN LARGE PART, THROUGH REDUCTIONS IN THE CGAC, WON'T TRANSPORTATION
     CUSTOMERS BE DENIED A PRICE BENEFIT FROM THE MERGER?

A.   No. Transportation customers will receive comparable benefits in three
     ways. First, transportation customers will receive a significant price
     benefit as a result of the ten-year base-rate freeze we are proposing to
     apply to Essex's current distribution rates. Second, the two-year $900,000
     reduction in the LDAC will apply both to transportation and sales
     customers. And finally, because most of the CGAC savings reflect the
     attainment of capacity-related cost reductions, transportation customers
     will receive those benefits in the form of lower-cost capacity releases to
     them. Although the details of the future capacity-release mechanism will
     depend on the outcome of the Massachusetts Gas Unbundling

                                                                   Exhibit JFB-1
                                                                  March 25, 1998
                                                                          Page 8


     Collaborative, it is envisioned that, whatever the eventual structure
     approved by the Department, the synergies achieved on behalf of Essex's
     customers will be reflected in the capacity-release mechanism, as applied
     to Essex's transportation customers.

Q.   HAVE YOU ESTIMATED THE POTENTIAL NEAR-TERM COST SAVINGS THAT COULD BE
     REALIZED THROUGH O&M EFFICIENCIES?

A.   Exhibit JFB-4 sets forth our analysis of savings available from O&M expense
     reductions. Essex's actual O&M expenses totaled $12,584,000, including
     labor expenses of $4,887,000 and non-labor expenses of $7,698,000, for the
     fiscal year ending August 31, 1997. We estimate that labor savings can be
     achieved through the reduction of 31 management positions and 19
     non-management positions. We estimate that the direct wage and salary cost
     reductions associated with these positions is approximately $2,479,000
     ($1,801,000 in management labor expenses and $678,000 in non-management).
     We also estimate that the elimination of employee benefits associated with
     these positions would result in an additional $969,000 of annual cost
     savings. Moreover, we estimate that other cost savings in the amount of
     $1,439,000 could result from the consolidation of programs and expenditures
     relating to insurance, audit and consulting fees, shareholder services and
     other general corporate functions. Therefore, in total, we estimate that
     O&M savings of $4,887,000, or 39 percent of Essex's total O&M expenses for
     the most recent fiscal year, are potentially attainable in the near term as
     a result of Eastern's acquisition of Essex.

                                                                   Exhibit JFB-1
                                                                  March 25, 1998
                                                                          Page 9


Q.   WHAT IS THE LIKELIHOOD THAT THE FULL AMOUNT OF THESE ESTIMATED SYNERGIES IN
     O&M EXPENSES WILL BE REALIZED?

A.   The primary risk involved in attaining the total estimated O&M savings of
     $4,887,000, is associated with the reduction of certain employee positions.
     These "at-risk" savings are estimated to be approximately $1,181,000, or 24
     percent of the total projected O&M savings.

     The large majority of the total at-risk savings, approximately $1,046,000,
     are associated with union positions that are covered by a collective
     bargaining agreement that will remain in effect until February 1999.
     Eastern will honor this contractual agreement. At the expiration of the
     contractual agreement, the parties are required to bargain in good faith.
     Therefore, the only way for Eastern to obtain the estimated union labor
     savings is to negotiate a settlement with the union. The remainder of the
     at-risk savings relate to general administrative expenses incurred to
     support these union positions.


Q.   PLEASE PROVIDE EXAMPLES OF OTHER FACTORS THAT COULD AFFECT THE ATTAINMENT
     OF YOUR O&M SAVINGS ESTIMATE.

A.   These uncertainties include, but are not limited to, how quickly and
     successfully we can manage coordination of field operations, facilities and
     systems. For example, in the area of field operations, we have assumed the
     following synergies can be achieved relatively quickly:

     O    Conversion of Essex's current manual service order system to Boston
          Gas' computer-aided dispatch system and dispatch operations

<PAGE>   58


                                                  Testimony of Joseph F. Bodanza
                                                                   Exhibit JFB-1
                                                                  March 25, 1998
                                                                         Page 10


     O    Consolidation of Essex's telephone inquiry and other customer activity
          functions into Boston Gas's inquiry center operation

     Further uncertainties that could adversely affect the timing and cost of
     attainable synergies include the extent of backlog in work required by the
     U.S. Department of Transportation, the condition of district regulator
     stations, and the accuracy and completeness of Essex's maps and records. In
     addition, we will need to determine the appropriate level of integration of
     systems, equipment, customer accounting, collection and billing-related
     services.

Q.   WHAT OTHER DIFFICULTIES ARE INVOLVED IN ASCERTAINING THE LEVEL OF POTENTIAL
     SAVINGS THAT COULD BE ATTAINED FROM THIS ACQUISITION?

A.   Since it is very difficult to predict how successful the integration of
     certain elements of Essex's operations with those of Boston Gas will be, it
     is difficult to project cost savings with a great degree of precision. In
     evaluating cost saving opportunities, it is important to keep in mind that
     there may be unforeseen factors that could delay the realization of savings
     or reduce expected savings. The savings estimates we have calculated
     represent our best efforts to identify and reduce known and measurable
     costs in advance of gaining the level of familiarity that will come only
     from the actual integration of Essex's resources and requirements with
     those of Boston Gas. In addition, as we move forward with our efforts to
     capture these synergies, we are committed to maintaining the high quality
     of service and reliability now enjoyed by Essex customers and will not
     compromise employee or public safety in achieving our cost savings goals.
     Since

                                                                         Page 11


     the Rate Plan provides Essex customers with an immediate 5 percent
     reduction and stabilizes rates for the next ten years, Eastern's
     shareholders are assuming all of the risk associated with achieving the
     estimated level of O&M savings.

Q.   HOW DOES THE RATE PLAN ALLOCATE THE BENEFITS OF THE MERGER BETWEEN ESSEX'S
     CUSTOMERS AND EASTERN'S SHAREHOLDERS?

A.   The benefits to Essex's customers will total approximately $57 million over
     ten years. This is composed of the CGAC and LDAC reductions of
     approximately $24 million and the $33 million benefit associated with the
     ten-year freeze in base rates. Moreover, we believe that additional gas
     cost savings may be achievable as a result of renegotiation of existing
     contracts, which is possible because of the enhanced purchasing power that
     will exist as a result of the merger. Near-term, identified savings from
     O&M synergies, estimated to be approximately $4.9 million annually, will be
     used to offset the cost of the merger incurred by Eastern. As discussed
     above, we believe that O&M cost savings will be more difficult to achieve.
     By relying upon O&M cost savings for reimbursement of the costs incurred to
     effect the merger, and instituting a freeze on base-rates, Eastern's
     shareholders are assuming both the risk of achieving these savings and the
     risk of cost increases as a result of inflation.

Q.   WHAT ARE THE COSTS ASSOCIATED WITH ACHIEVING THE MERGER BENEFITS FOR ESSEX
     CUSTOMERS?

A.   The costs incurred to achieve the acquisition fall into the following three
     categories: (1) merger integration costs incurred to achieve the synergies
     that will

<PAGE>   60


                                                  Testimony of Joseph F. Bodanza
                                                                   Exhibit JFB-1
                                                                  March 25, 1998
                                                                         Page 12


     ultimately reduce the costs of Essex's operations; (2) transaction costs
     related to the completion of the merger; and (3) the acquisition premium,
     which will be reflected in the earnings dilution experienced by Eastern's
     shareholders as a result of the exchange of Eastern's common stock for the
     common stock of Essex.

Q.   PLEASE DESCRIBE EACH OF THESE COST CATEGORIES IN MORE DETAIL.

A.   The first category of costs are those necessary to ensure the successful
     and timely integration of Essex's and Boston Gas' operations. These costs
     include early retirement and severance costs incurred to reduce redundant
     positions, retraining costs, system and facility consolidation costs
     required for efficient operations, customer and employee communication
     costs necessary to inform both groups of the effects of the merger. An
     itemization of these costs is set forth in Exhibit JFB-5.

     The second category of costs relating to the transaction involves expenses
     incurred in completing the merger. These non-tax-deductible costs involve
     investment banking fees, legal and regulatory expenses, accounting fees,
     filing fees and miscellaneous expenses. An itemization of these cost
     estimates is set forth in Exhibit JFB-6. The sum of the first two
     categories is approximately $15 million.

     The third category is the acquisition premium required to complete the
     acquisition and realize the synergies. Because the acquisition will be
     effected through the issuance and exchange of Eastern common stock with the
     common stock of

<PAGE>   61


                                                  Testimony of Joseph F. Bodanza
                                                                   Exhibit JFB-1
                                                                  March 25, 1998
                                                                         Page 13


     Essex, the acquisition premium will be reflected in the earnings dilution
     experienced by Eastern's shareholders as a result of the exchange. A
     discussion of this cost and the extent to which earnings dilution is
     expected to occur is addressed by Mr. Murphy in his testimony. As described
     in Mr. Murphy's testimony, earnings dilution for Eastern shareholders is
     estimated to be $46 million. The sum of the three cost categories results
     in a total acquisition cost of $61 million.

Q.   MR. MURPHY DESCRIBES THE ACQUISITION PREMIUM RESULTING FROM THIS POOLING OF
     INTERESTS TRANSACTION ACQUISITION TO BE $46 MILLION. HAVE YOU ANALYZED THE
     ACQUISITION PREMIUM AS IF THE TRANSACTION WERE ACCOUNTED FOR AS A PURCHASE
     TRANSACTION?

A.   Yes. Referring to Exhibit JFB-7, I have computed the acquisition premium
     assuming that Eastern purchased all outstanding and issuable (as of
     December 1, 1997) shares of Essex at $47.50 per share. The resulting
     acquisition premium of $26.49 per share represents the difference between
     the price paid and the book value per share. A total premium of $47.1
     million is computed by multiplying $26.49 times the 1.778 million shares of
     Essex. Exhibit JFB-8 computes a revenue requirement of $81 million that
     would be necessary under purchase accounting to allow shareholders to earn
     on and recover their investment based on an up-front premium of $47.1
     million paid in a purchase transaction.

Q.   HOW DOES EASTERN PROPOSE TO RECOUP THESE ACQUISITION-RELATED COSTS?

A.   The total savings that must be realized by Eastern shareholders so that
     they may recover the costs associated with the transaction is approximately
     $61 million.

<PAGE>   62


                                                  Testimony of Joseph F. Bodanza
                                                                   Exhibit JFB-1
                                                                  March 25, 1998
                                                                         Page 14


     The Rate Plan, as described above, implicitly provides an opportunity for
     Eastern's shareholders to recover those costs, although Eastern is bearing
     all risks of capturing O&M synergies and, at the same time, absorbing the
     impact of inflationary cost increases over the period of the Rate Plan.
     Thus, approval of the Rate Plan will implicitly recognize the opportunity
     to recover the acquisition costs over a ten-year period.


Q.   WHAT RATIONALE DO YOU HAVE FOR SEEKING REGULATORY RECOGNITION OF THE
     ACQUISITION COSTS?

A.   Eastern and Essex strongly believe that there are substantial synergies and
     cost savings resulting from the merger and, in fact, that assumption serves
     as the primary motivating factor for the shareholder investment in this
     proposal. At the same time, as discussed above and in the testimony of
     Messrs. Flaherty and Murphy, there are real costs associated with
     accomplishing this transaction. Thus, in order to effect the transaction
     and to attain the resultant benefits for customers, Eastern's shareholders
     must make a substantial investment and recover their investment. In the
     absence of a regulatory policy that recognizes, in some equitable manner,
     that such costs are a necessary component of a transaction that will
     ultimately result in substantial cost savings for customers, shareholders
     will not put their capital at risk to accomplish a transaction. Mergers
     such as the one proposed here will provide customers with the permanent
     benefit of harnessed synergies and increased efficiencies. However, these
     customer benefits can be achieved only if the Department recognizes that
     there is a direct linkage between

                                                                   Exhibit JFB-1
                                                                  March 25, 1998
                                                                         Page 15


     these benefits and the investment necessary to bring them about and
     provides a reasonable opportunity for shareholders to recover the costs of
     the acquisition. We believe the Rate Plan as proposed in this filing
     appropriately achieves this balance.


III. THE MERGER'S CONSISTENCY WITH THE PUBLIC INTEREST

Q.   WHAT FACTORS DOES THE DEPARTMENT CONSIDER IN DETERMINING WHETHER THE MERGER
     IS CONSISTENT WITH THE PUBLIC INTEREST?

A.   In Mergers and Acquisitions, D.P.U. 93-167-A (1994), the Department stated
     that it will generally consider the following factors in order to assess
     whether a merger is consistent with the public interest:

          (1)  Impact on rates;

                                                                   Exhibit JFB-1
                                                                  March 25, 1998
                                                                         Page 16


Q.   WHAT IMPACT WILL THE MERGER HAVE ON THE RATES OF ESSEX?

A.   As described above, the Rate Plan provides that Essex's customers would
     receive an immediate 5 percent reduction in their total burner-tip price
     upon the consummation of the acquisition and would not be subject to base
     rate increases for ten years. Because the acquisition is necessary to
     achieve the economies of scale and other efficiencies that will produce the
     cost savings, and because a significant portion of such cost savings will
     be passed on to customers in the form of reduced prices, the merger is
     consistent with the public interest under G.L. c. 164, ss. 96.

Q.   WHAT IMPACT WILL THE ACQUISITION HAVE ON THE QUALITY OF SERVICE TO CURRENT
     ESSEX CUSTOMERS?

A.   Because the service territories of Boston Gas and Essex are contiguous, the
     operations of Essex can be operated more efficiently when coordinated with
     Boston Gas' overall operations. Eastern and Boston Gas are committed to
     maintaining the high level of service quality and reliability provided by
     Essex. Moreover, Boston Gas will be able to rely on its information systems
     resources and customer service experience to enhance the quality of service
     to Essex's customers.

Q.   IN GENERAL, WHAT WOULD BE THE NET SAVINGS RESULTING FROM THE PROPOSED
     MERGER?

A.   As described above, the Eastern acquisition of Essex has the potential to
     yield substantial cost reductions associated with: (1) gas supply and
     dispatching

                                                                         Page 17


     operations; (2) distribution system operation (i.e., reductions in total
     facilities, vehicles, and testing and repair functions); (3) customer
     service and accounting functions, including billing and credit and
     collection; and (4) other general, corporate and administrative functions.
     The savings associated with O&M activities are estimated to be
     approximately $4.9 million annually. The savings associated with gas supply
     operations are expected to be at least $22 million over the next ten years,
     based on the savings identified in Mr. Luthern's testimony.

Q.   WHAT IMPACT WILL THE PROPOSED MERGER HAVE ON COMPETITION WITHIN THE GAS
     INDUSTRY?

A.   The acquisition of Essex will facilitate greater competition in the gas
     industry. Both Boston Gas and Essex are participating in the Massachusetts
     Gas Unbundling Collaborative, and are operating under the assumption that
     natural gas distribution companies will be undergoing further unbundling in
     the not-too-distant future. By combining the resource portfolios of the two
     companies, Boston Gas will be in a better position to minimize transition
     costs and to streamline and standardize systems for third-party gas
     marketers in the Essex service area. Boston Gas anticipates using its
     broker management system to facilitate communications with marketers in the
     Essex service territory. The proposed merger will allow for the combination
     of two regulated utilities whose rates and services would continue to be
     subject to the Department's regulatory authority. Accordingly, the
     Department's continued regulation of the distribution

     function of both companies negates any opportunity to exploit market power
     as a result of the merger.

Q.   HOW WILL THE FINANCIAL INTEGRITY OF ESSEX COMPARE TO THAT OF THE PRE-MERGER
     ESSEX?

A.   As mentioned in the testimony of Mr. Hastings, Essex is a relatively small
     company with limited access to financial resources. Post-merger, Essex will
     be a subsidiary of Eastern and will have access to the broader financial
     resources of Eastern. It is anticipated that Essex's cost of debt and
     financing of gas inventory costs will be reduced upon combining its
     requirements with those of Boston Gas. Currently, Essex's external working
     capital needs and gas inventory financing requirements are accomplished
     through lines of credit with various banking institutions versus the less
     costly commercial paper programs that Boston Gas has in place. Any savings
     realized by utilizing Boston Gas' commercial paper programs would be flowed
     back to customers through the CGAC and thus provide Essex customers
     additional savings over those estimated in my testimony.

Q.   HOW WILL THE BENEFITS OF THE MERGER BE DISTRIBUTED BETWEEN EASTERN
     SHAREHOLDERS AND ESSEX CUSTOMERS?

A.   Essex customers will receive an immediate 5 percent reduction in their
     overall burner-tip gas price. In addition, Essex's base rates will be
     frozen at current levels for a period of ten years, subject only to
     exogenous changes. Thus, Essex's rates will be both lower and more stable
     as a result of the merger. It is noteworthy that, absent the merger, Essex
     was planning to request a rate increase within the

                                                                         Page 19


     next two years. Instead, customers will receive an immediate 5 percent rate
     reduction and no base rate increases for ten years. At the same time, the
     Rate Plan would provide Eastern's shareholders with the opportunity to
     capture a portion of the merger-related synergies and to be reimbursed for
     the acquisition costs incurred to bring real and immediate benefits to
     Essex customers.


Q.   WHAT ARE THE SOCIETAL COSTS AND BENEFITS PRODUCED BY THE MERGER?

A.   On balance, the overall result of the merger will be a more efficient use
     of combined resources and lower gas prices to consumers, which may provide
     the impetus for greater economic efficiency in Essex's service territory.
     Societal costs resulting from the elimination of redundant positions are
     expected to be minimal in this case because of Eastern's commitment to
     maintain a presence in the community and to undertake all reasonable
     efforts to provide any employees who may be displaced with access to
     employee placement programs.

     According to the Merger Agreement, any employees who are terminated or
     whose positions are eliminated will be entitled to participate in job
     opportunity and employee placement programs. We also intend to present
     opportunities for employment at Boston Gas and Eastern to Essex employees
     whose positions have been eliminated.

Q.   WHAT IMPACT WILL THE MERGER HAVE ON ECONOMIC DEVELOPMENT IN ESSEX'S SERVICE
     TERRITORY?

A.   As stated earlier, upon consummation of the merger, delivered gas prices
     for all Essex customers will be reduced by 5 percent and base rates will be
     frozen for a period of ten years. Since Essex was planning to seek a base
     rate increase within the next two years, the merger will result in
     considerably lower, and more stable, prices both in the near and long term.
     The savings in gas bills for all customers will be of significant benefit
     to the local economy, and therefore, should have a positive effect on
     economic development within Essex's service territory. Given the
     Commonwealth's location at the end of the interstate pipeline network,
     utility consolidation may be the only significant means of reducing energy
     costs and making Massachusetts industry more competitive.


Q.   ARE THERE ANY OTHER REASONABLE AND COST-EFFECTIVE WAYS FOR ESSEX TO ACHIEVE
     THE MERGER BENEFITS PREVIOUSLY DISCUSSED WITHOUT BEING ACQUIRED BY EASTERN?

A.   Smaller companies generally do not have the ability to capture the
     economies of scale and/or scope that are derived from more expansive
     operations. Essex's relatively small size prevents it from attaining
     economies of scale and from realizing the attendant savings that result
     from such economies. Potential elimination of redundant facilities,
     personnel and resources, together with a gas supply plan coordinated with
     the operations of Boston Gas will permit Essex to obtain the advantages of
     such economies for its customers.

Q.   BASED ON YOUR KNOWLEDGE OF THESE COMPANIES AND THE AREA THEY SERVE, IS THE
     PROPOSED MERGER CONSISTENT WITH THE PUBLIC INTEREST?

A.   Yes, for all of the reasons stated above, and in consideration of the
     expected benefits described in the testimony of Mr. Luthern, the merger is
     consistent with the public interest, as required by G.L. c. 164, ss. 96.

Q.   DOES THIS CONCLUDE YOUR TESTIMONY?

A.   Yes, it does.

     of Boston Gas, and to explain how these efficiencies will be attained so as
     to reduce future gas supply costs to Essex customers, while fairly
     compensating Boston Gas customers for the value associated with the assets
     used to serve Essex customers.

II.  EFFECT OF MERGER ON GAS SUPPLY PLANNING AND THE POTENTIAL FOR REDUCED GAS
     COSTS

Q.   WILL THE PROPOSED ACQUISITION CREATE THE OPPORTUNITY FOR SYNERGIES
     ASSOCIATED WITH GAS SUPPLY PLANNING AND PURCHASING FOR ESSEX'S CUSTOMERS?

A.   Yes, the acquisition will facilitate the development of a more efficient
     gas supply plan for Essex. Re-optimization of Essex's portfolio will be
     possible as a result of the coordination of Boston Gas' and Essex's gas
     supply planning and acquisition efforts. Such coordination will create the
     opportunity to more efficiently use the resources of both companies and
     allow Essex's customers to benefit from the economies of scale gained
     through the aggregation of supply resources. The opportunity to capture
     such synergies will be enhanced because the service territories of Essex
     and Boston Gas are geographically contiguous, and connected through the
     Tennessee Gas Pipeline Company ("Tennessee").

Q.   PLEASE PROVIDE A BRIEF DESCRIPTION OF ESSEX COUNTY GAS COMPANY'S CURRENT
     SUPPLY PORTFOLIO.

A.   As illustrated in Exhibit WRL-2, Essex currently has a long-haul
     transportation contract with Tennessee for 15,728 Mcf per day. Essex has
     gas supply commodity contracts with Aquila Energy, Enron Capital & Trade
     Resources Corp., El Paso Energy Marketing, Coral Energy and Natural Gas
     Clearinghouse

                                                                   Exhibit WRL-1
                                                                  March 25, 1998
                                                                          Page 3


     for delivery of firm gas supplies totaling 15,728 MMBtu per day, which are
     transported to Essex's citygates on the Tennessee pipeline. Essex has
     bundled supply contracts with Boundary Gas, Inc. and Alberta Northeast,
     Limited for baseload gas supplies delivered from the Canadian border under
     domestic transportation arrangements with Tennessee and the Iroquois Gas
     Transmission system, totaling approximately 3,621 MMBtu per day. Essex has
     several contracts for upstream underground storage and transportation,
     including a total of 1.162 Bcf of storage capacity and 9,241 MMBtu of peak
     day deliverability. Essex also maintains LNG and propane facilities in
     Haverhill with storage capacity of 0.440 Bcf and 0.042 Bcf, respectively,
     with output rates of 34,400 MMBtu per day and 8,400 MMBtu per day,
     respectively. In addition, Essex has a contract with Distrigas of
     Massachusetts Corporation for the purchase of LNG in liquid or vapor form
     ranging from 0.604 to 0.906 Bcf annually.


Q.   ARE YOU FAMILIAR WITH THE MANNER IN WHICH ESSEX'S UPSTREAM PIPELINE AND
     STORAGE VOLUMES ARE DELIVERED TO THE ESSEX CITYGATE?

A.   Yes. Boston Gas subscribes to the identical services on Tennessee as Essex,
     and as such transports its long-haul domestic supplies, short-haul storage
     supplies and its Canadian supplies under the exact same tariffs.


Q.   PLEASE PROVIDE A BRIEF DESCRIPTION OF BOSTON GAS COMPANY'S CURRENT SUPPLY
     PORTFOLIO.

A.   Boston Gas has capacity entitlements on multiple upstream pipelines that
     provide direct access to domestic and Canadian supply resources. Of these
     upstream

                                                                   Exhibit WRL-1
                                                                  March 25, 1998
                                                                          Page 4

     pipelines, two pipeline companies, Algonquin Gas Transmission Company
     ("Algonquin") and Tennessee provide direct service to Boston Gas'
     citygates.

     The interstate pipeline capacity available to meet system requirements and
     to fill underground storage can be logically separated into two components.
     First, Boston Gas holds long-haul capacity to transport supply from the
     producing regions of the lower 48 states. Aggregated at Boston, this
     capacity allows for transportation of approximately 242,000 MMBtu per day.
     Boston Gas also holds short-haul capacity that is used to transport
     approximately 167,000 MMBtu per day, from upstream underground storage
     fields to the citygates of Boston Gas. Also, a component of Boston Gas'
     pipeline supply originates in Canada, supplying 54,000 MMBtu per day to its
     citygate.

     In addition, the Company has contracted with pipeline companies and others
     for the storage of natural gas in underground storage fields located in
     Pennsylvania, New York, Maryland and West Virginia. These contracts provide
     for storage capacity of 17.3 Bcf and peak day deliverability of 195,000 Bcf
     per day.

     The Company also utilizes upon supplemental facilities, i.e., local
     production plants, to store and vaporize liquefied natural gas ("LNG") and
     liquid propane supplies. The Company has LNG storage capacity of 3.14 Bcf
     and can deliver maximum daily quantities of 291,400 MMBtu per day from
     these facilities. The

                                                                   Exhibit WRL-1
                                                                  March 25, 1998
                                                                          Page 5


     Company also has propane storage capacity of 1.584 Bcf and can deliver up
     to 70,000 MMBtu per day from those facilities.


Q.   ON WHAT BASIS DID YOU DETERMINE THAT IT WAS POSSIBLE TO CAPTURE GAS SUPPLY
     SYNERGIES FOR THE TWO SYSTEMS?

A.   I have reviewed the gas supply portfolio of Essex to determine the maximum
     daily quantity, annual delivery limitations, and termination dates of each
     contract. I also reviewed Essex's gas sendout requirements and each of its
     contracts to determine which contracts, if any, could be reduced or
     displaced as a result of the ability to coordinate Essex's gas supply
     portfolio with that of Boston Gas.


Q.   HAVE YOU BEEN ABLE TO IDENTIFY AND QUANTIFY POTENTIAL GAS COST SAVINGS AS A
     RESULT OF THAT ANALYSIS?

A.   Yes. Based on my review of Essex's resource portfolio and gas requirements,
     Essex could release its Tennessee long-haul capacity contract of 15,728 Mcf
     per day and obtain 70 percent of the current maximum tariff rate, or $2.2
     million, in the capacity-release market each year until the contract
     expires on November 1, 2000. Upon expiration of the term of the Tennessee
     contract, Essex customers would experience gas cost savings thereafter of
     $3.1 million annually. In addition, I estimate that Essex could attain
     approximately $300,000 in commodity cost savings annually as a result of
     renegotiating Essex's domestic supply and combining Essex's supply
     purchases with those of Boston Gas, which would create increased purchasing
     power.

                                                                   Exhibit WRL-1
                                                                  March 25, 1998
                                                                          Page 6


Q.   HAVE YOU BEEN ABLE TO IDENTIFY ANY OTHER POSSIBLE COST SAVINGS THAT COULD
     BE ATTAINED AS A RESULT OF THE COORDINATION OF THE RESOURCE PORTFOLIOS?

A.   We have not identified any contracts, other than the Tennessee long-haul
     contract, that could be reduced or eliminated without jeopardizing the
     ability to meet Essex's system requirements. We believe that additional
     cost savings may be achievable; however, at this point, such cost
     reductions are difficult to estimate because the attainment of those
     additional savings is dependent upon the ability of Essex and Boston Gas to
     renegotiate existing capacity commitments.


Q.   WHAT ARE THE TOTAL GAS SUPPLY SAVINGS THAT YOU ESTIMATE WOULD BE ATTAINABLE
     AND HOW DOES THAT COMPARE TO ESSEX'S TOTAL GAS COSTS?

A.   As set forth above, I estimate that gas cost savings of $2.5 million
     annually will be achieved and that those savings will increase to $3.4
     million in 2001 and continue at that level thereafter. This total reflects
     cost savings of $2.2 million annually until the Tennessee contract expires
     as a result of the release of Tennessee pipeline capacity and $300,000
     annually in commodity cost savings. In 2001 and beyond, total gas cost
     savings are estimated to increase to $3.4 million as a result of
     eliminating the cost of the Tennessee contract combined with the reduction
     in commodity costs.

     Essex's fixed capacity costs total approximately $8.1 million. Thus, the
     $2.2 million in estimated savings resulting from the release of the
     Tennessee pipeline capacity represents approximately 27 percent of Essex's
     fixed capacity costs, and

                                                                   Exhibit WRL-1
                                                                  March 25, 1998
                                                                          Page 7


     such cost savings will increase to approximately 38 percent at the
     expiration date of the Tennessee contract.


Q.   WILL THE USE OF BOSTON GAS GAS SUPPLY RESOURCES TO ATTAIN EFFICIENCIES IN
     THE ESSEX PORTFOLIO AFFECT THE ABILITY OF BOSTON GAS CUSTOMERS TO BENEFIT
     FROM CAPACITY-RELEASE OPPORTUNITIES?

A.   Yes. The opportunity for the realization of synergies and associated cost
     savings as a result of the merger rests in the ability of Essex and Boston
     Gas to coordinate their gas supply planning and purchasing operations,
     especially since the service territories are contiguous. This coordinated
     planning will significantly increase the ability of Essex and Boston Gas to
     utilize their resources in an efficient manner and at a higher load factor.
     As a result, some capacity-release opportunities on the Boston Gas system
     will be foregone.

     To determine the impact of this arrangement on Boston Gas customers, we
     have analyzed the use of Boston Gas resources to meet system requirements,
     with and without Essex's operations. Specifically, we performed a dispatch
     analysis using Boston Gas resources to meet Boston Gas system requirements,
     in isolation, and a dispatch analysis of Essex resources to meet Essex
     system requirements. This analysis allowed us to determine the incremental
     levels of Boston Gas resources that would be utilized to substitute for
     Essex's Tennessee long-haul contract. As a result, we were able to
     determine that certain resources of Boston Gas would be used to serve Essex
     customers that would otherwise be released into the marketplace.

                                                                   Exhibit WRL-1
                                                                  March 25, 1998
                                                                          Page 8


Q.   HAVE YOU BEEN ABLE TO QUANTIFY THE VALUE OF THESE FOREGONE CAPACITY-RELEASE
     OPPORTUNITIES?

A.   In order to quantify the value of any foregone capacity-release
     opportunities, we used the dispatch analysis to identify the particular
     resources of the Boston Gas portfolio that would be used to serve Essex
     customers. We then calculated the value of the incremental capacity using
     market values from the 1997/98 heating season for capacity releases
     associated with the resources identified in the dispatch analysis. This
     analysis is attached as Exhibit WRL-3. As demonstrated in Exhibit WRL-3,
     the total value of foregone capacity-release opportunities for the normal
     split year 1998/99 is estimated to be $1.04 million.


Q.   HOW DO YOU PROPOSE TO PROVIDE ESSEX'S CUSTOMERS WITH GAS COST SAVINGS AND
     TO COMPENSATE BOSTON GAS CUSTOMERS FOR FOREGONE CAPACITY-RELEASE
     OPPORTUNITIES?

A.   As set forth in the Rate Plan proposed by Mr. Bodanza, gas cost savings
     will be passed on to customers through the normal operation of Essex's Cost
     of Gas Adjustment Clause ("CGAC"). Although reductions in fixed capacity
     costs and commodity costs are estimated to be $2.5 million annually over
     the first two years of the Rate Plan, these savings are achieved only by
     virtue of the coordinated gas supply activities of Boston Gas and Essex.
     Thus, in order to ensure that Boston Gas customers are held harmless and do
     not subsidize Essex customers, the Essex CGAC must reflect both the
     reduction in the gas supply costs of Essex portfolio ($2.5 million) and the
     Boston Gas opportunity revenues that were foregone to serve Essex customers
     ($1.04 million). Therefore, for the first year of the Rate

                                                 Testimony of William R. Luthern
                                                                   Exhibit WRL-1
                                                                  March 25, 1998
                                                                          Page 9

     Plan, we propose to pass net gas cost savings of $1.46 million to Essex
     customers through the Essex CGAC and to credit the Boston Gas CGAC for
     $1.04 million to reflect projected foregone opportunity revenues.


Q.   HOW HAVE YOU DETERMINED THE VALUE OF THE FOREGONE REVENUE AND HOW WILL THAT
     REVENUE BE ACCOUNTED FOR AFTER THE FIRST YEAR OF THE RATE PLAN?

A.   In pursuing capacity-release opportunities for Boston Gas customers, we
     normally run a dispatch analysis each year prior to the start of the
     heating season and make projections as to the availability of capacity for
     release in each month during the upcoming year. Generally, Boston Gas will
     make such capacity available for release by November 1 for the entire
     season. In our experience, this approach avoids the need for daily trades
     during the heating season (which would impose a significant administrative
     burden upon the Company), and maximizes the volume and value of the
     capacity being placed on the secondary market.

     Consistent with that approach, we have developed the analysis set forth in
     Exhibit WRL-3 to estimate the amount of the foregone revenues that would
     occur as a result of the merger. Going forward, we would propose to prepare
     such an analysis at the start of each heating season, with the objective of
     estimating the revenues that would have been available for Boston Gas
     customers had the capacity been released rather than utilized to meet the
     system requirements of Essex. In establishing the dollar value of the
     foregone revenues, we propose to use the most recent available data each
     year to estimate the value that capacity

<PAGE>   86

                                                                   Exhibit WRL-1
                                                                  March 25, 1998
                                                                         Page 10


     would receive on the secondary release market. Once we have determined the
     value of the foregone revenues, we will lock-in that transfer by charging
     the Essex CGAC and crediting the Boston Gas CGAC for that amount. In this
     way, we project Essex customers will receive net benefits in the form of
     reduced gas costs in the first two years after the merger, totaling
     approximately $1.5 million annually, while Boston Gas customers will be
     compensated for the use of that portion of the Boston Gas system necessary
     to serve Essex customers, i.e., by $1.04 million the first year. Following
     the expiration date of Essex's Tennessee long-haul capacity contract on
     November 1, 2000, we project the net gas cost savings to Essex customers
     will increase from approximately $1.5 to approximately $2.4 million
     annually.


Q.   DOES THIS COMPLETE YOUR TESTIMONY?

A.   Yes, it does.

The Securities and Exchange Commission
Washington, D.C. 20549


     Re: Eastern Enterprises - Form U-1
         ------------------------------

Ladies and Gentlemen:

     This opinion is furnished to you in connection with the Form U-1 (the "Form
U-1") to be filed with the Securities and Exchange Commission pursuant to the
Public Utility Holding Company Act of 1935, as amended, by Eastern Enterprises,
a Massachusetts voluntary association ("Eastern"). The Form U-1 is being filed
in connection with the acquisition by Eastern of all of the outstanding shares
(the "Essex County Shares") of common stock, no par value, of Essex County Gas
Company, a Massachusetts gas utility company ("Essex County") in exchange for
shares (the "Eastern Shares") of common stock, $1.00 par value, of Eastern. The
Eastern Shares are to be issued pursuant to an Agreement and Plan of Merger,
dated as of December 19, 1997 (the "Merger Agreement"), by and between Essex
County and Eastern providing for the merger (the "Merger") of a Massachusetts
corporation to be formed by and to be the wholly-owned subsidiary of Eastern
with and into Essex County, as a result of which the Essex County will be the
surviving corporation.

     We have acted as counsel for Eastern in connection with the Merger
Agreement and the proposed issuance of the Eastern Shares contemplated thereby.
For purposes of this opinion, we have examined and relied upon such documents,
records, certificates and other instruments as we have deemed necessary.

     We express no opinion as to the applicability of, compliance with or effect
of Federal law or the law of any jurisdiction other than The Commonwealth of
Massachusetts.

     Based on the foregoing, we are of the opinion that:

Securities and Exchange Commission     -2-                    March 31, 1998


     1. Assuming consummation of the Merger in accordance with the terms of the
Merger Agreement, the Merger will comply with all applicable provisions of the
laws of The Commonwealth of Massachusetts.

     2. Eastern is validly organized and duly existing as an unincorporated
voluntary association under the laws of The Commonwealth of Massachusetts.

     3. The Eastern Shares have been duly authorized and, when issued and
delivered in accordance with the terms of the Merger Agreement, will be validly
issued, fully paid and non-assessable and entitle the holders thereof to all the
rights and privileges pertaining thereto as set forth in the Declaration of
Trust dated July 18, 1929, as amended and By-laws of Eastern.

     4. Assuming consummation of the Merger in accordance with the terms of the
Merger Agreement, the Essex County Shares to be acquired by Eastern pursuant to
the terms of the Merger Agreement will be legally acquired by Eastern.

     5. The consummation of the Merger in accordance with the terms of the
Merger Agreement will not violate any legal rights of the holders of any issued
and outstanding securities of Eastern or any of its affiliates.

     We hereby consent to the filing of this opinion as an exhibit to Eastern's
Form U-1.

     It is understood that this opinion is to be used only in connection with
the Form U-1 and may not be relied upon for any other purpose.


                                        Very truly yours,

combined statement of operations herein, the financial information of Boston Gas
for the fiscal year ended December 31, 1997 has been combined with Essex
County's financial information for the twelve months ended November 30, 1997.

The accounting policies of Eastern, Boston Gas and Essex County are currently
being studied from a conformity perspective. The impact of conforming accounting
policies (if any) is not presently estimable. If conforming adjustments are
required, they will be recorded as part of the restatement of prior periods as
required by the pooling-of-interests method. However, certain amounts in the
historical financial statements of Boston Gas and Essex County have been
reclassified to present consistent pro forma financial information. There were
no material intercompany transactions between Boston Gas and Essex County during
the periods presented.

(2)  MERGER-RELATED EXPENSES

Eastern and Essex County will incur investment banking, legal, accounting and
other transaction costs as a result of the Merger. Based on information
currently available, these costs will total approximately $4.6 million and have
been and will be expensed in the period incurred. Since the Merger has not been
consummated, the Merger expenses can only be estimated at this time, and are
subject to revision as further information becomes available.

(3)  COMMON STOCKHOLDERS' INVESTMENT

The common stock and paid-in capital accounts of Boston Gas and Essex County
have not been restated for the Merger due to the fact that Essex County common
stock is being exchanged for Eastern common stock, not Boston Gas common stock,
as provided in the Merger Agreement. The exchange ratio is one Essex County
common share for 1.183985 shares of Eastern common stock.
