                          APPLICATION/DECLARATION UNDER
                          SECTIONS 9, 10, AND 11 OF THE
                   PUBLIC UTILITY HOLDING COMPANY ACT OF 1935

Item 1.  Description of Proposed Transaction

A.       Introduction

          This  Application/Declaration  seeks  approval  pursuant  to  Sections
9(a)(2) and 10 of the Public Utility Holding Company Act of 1935 (the "Act") for
the proposed acquisition by KeySpan Corporation  ("KeySpan") and ACJ Acquisition
LLC ("ACJ"), a direct wholly-owned subsidiary of KeySpan, of Eastern Enterprises
("Eastern"),  pursuant  to which  Eastern  will  become a  direct,  wholly-owned
subsidiary of KeySpan (the  "Transaction").  Following the  consummation  of the
Transaction,  KeySpan will register with the Securities and Exchange  Commission
(the "Commission") as a holding company under the Act.1

          The  Transaction  is expected to produce  substantial  benefits to the
public, investors and consumers. Among other things, KeySpan and Eastern believe
that the  Transaction  will  allow  shareholders  to  participate  in a  larger,
financially  stronger  company,  that,  through  a  combination  of the  equity,
management,  human resources and technical expertise of each company,  they will
be  able  to  achieve  increased  financial  stability  and  strength,   greater
opportunities  for  earnings,  reduction of  operating  costs,  efficiencies  of
operation,  better use of  facilities  for the  benefit of  customers,  improved
ability  to use new  technologies,  and  greater  retail  and  industrial  sales
diversity. In this regard, KeySpan and Eastern believe that synergies created by
the Transaction will generate substantial cost savings. KeySpan and Eastern have
estimated  the dollar  value of certain  initial  synergies  resulting  from the
Transaction to be  approximately  $24 to $29 million,  phased in over a two year
period.  Moreover,  KeySpan  believes that the combined  companies  will be in a
better position to compete in the restructured  and competitive  energy industry
with  other  industry  participants  than  they  would  be  acting  alone.  Upon
consummation of the Transaction  (and giving effect to Eastern's  acquisition of
EnergyNorth,  Inc.  ("EnergyNorth"),  as  discussed  below,  KeySpan and Eastern
together,  through  their  public  utility  company  subsidiaries,   will  serve
approximately  2.4 million retail gas customers and

_______________
1 KeySpan will file a separate  application/declaration(s)  with the  Commission
for  authorizations  to engage in certain  activities  once the  Transaction  is
consummated  and KeySpan  registers as a holding company under the Act ("Omnibus
Application")  including  authorizations  pursuant  to Section 13 of the Act and
Rule 88 for service  companies . KeySpan requests that the Commission review and
rule   on   the    Omnibus    Application(s)    contemporaneously    with   this
Application/Declaration.


                                       2

provide  electric  service to one  customer,  the Long  Island  Power  Authority
("LIPA"),  which provides retail electric service to  approximately  1.1 million
customers.

1.       General Request

         Pursuant to Sections  9(a)(2) and 10 of the Act, KeySpan and ACJ hereby
request authorization and approval of the Commission to acquire, by means of the
Transaction,  all of the issued and  outstanding  common  stock of Eastern  and,
indirectly,  all of the common stock of Eastern's utility subsidiaries described
below.  Following  completion  of the  Transaction,  KeySpan will  register as a
holding  company  pursuant to Section 5 of the Act.  Accordingly,  KeySpan  also
requests  Commission  approval  for the  retention  by KeySpan  of the  existing
businesses, investments and non-utility activities of KeySpan and Eastern.

         On January 5, 2000, Eastern filed an  application/declaration  with the
Commission ("Eastern/EnergyNorth Application") requesting authorization pursuant
to Sections  9(a)(2) and 10 of the Act to acquire all the issued and outstanding
common stock of EnergyNorth  (hereafter  referred to as the "ENI  Transaction").
(See File No. 70-9605) Both Eastern and EnergyNorth are exempt holding companies
pursuant  to Section  3(a)(1) of the Act.  If the  Commission  approves  the ENI
Transaction,  upon  consummation of the  transaction,  EnergyNorth will become a
direct subsidiary of Eastern, and, therefore,  an indirect subsidiary of KeySpan
through    consummation   of   the    Transaction.    For   purposes   of   this
Application/Declaration,  KeySpan has assumed that the ENI  Transaction  will be
approved    concurrently    with    the    Transaction.     Accordingly,    this
Application/Declaration  addresses an indirect acquisition by KeySpan and ACJ of
EnergyNorth  through their  acquisition of Eastern.  However,  KeySpan and ACJ's
request for approval of the Transaction is not contingent on Commission approval
of the  ENI  Transaction  and if  such  transaction  is  not  approved,  KeySpan
nevertheless requests that the Commission approve the Transaction without giving
effect to Eastern's acquisition of EnergyNorth.

         In  the   Eastern/EnergyNorth   Application/Declaration,   Eastern  and
EnergyNorth  have requested that the Commission  find that each will continue to
be exempt holding  companies under Section 3(a)(1) of the Act.  KeySpan requests
that, to the extent the  Commission  grants Eastern and  EnergyNorth  exemptions
under Section 3(a)(1),  the Commission confirm that Eastern and EnergyNorth will
continue  to  qualify  for  exemptions  under  Section  3(a)(1)   following  the
consummation  of  the  Transaction  and  KeySpan's  registration  as  a  holding
company.2

         Likewise,  KeySpan requests the Commission's  confirmation that KeySpan
Energy Corporation ("KEC"), a direct,  wholly-owned  subsidiary of KeySpan, will
continue  to be

______________

2 As discussed  more fully in Item  3.A.4.b.i  of this  Application/Declaration,
EnergyNorth  will be eliminated as an  intermediary  holding  company as soon as
practicable after consummation of the Transaction.


                                       2
<PAGE>

an  exempt  holding   company  under  Section   3(a)(1)  of  the  Act  following
consummation  of the  Transaction.  KEC is a holding company which directly owns
100% of the  outstanding  voting  securities  of The Brooklyn  Union Gas Company
("Brooklyn  Union"),  a gas utility  company  which  operates  gas  distribution
facilities,  and  sells gas at  retail,  within  the  state of New York.  KEC is
currently an exempt holding company under Section 3(a)(1) of the Act and Rule 2.

2.       Overview of the Transaction

         Pursuant to the  Agreement  and Plan of Merger  dated as of November 4,
1999,  as  modified by  Amendment  No. 1 dated  January  26,  2000 (the  "Merger
Agreement"),   KeySpan,  through  ACJ,  will  acquire  all  of  the  issued  and
outstanding  common stock of Eastern in an all-cash  transaction.  A copy of the
Merger Agreement is provided as Exhibit B hereto.  The Transaction  contemplates
that ACJ, a Massachusetts  limited liability  company and a direct  wholly-owned
subsidiary  of  KeySpan,  will be merged into  Eastern  with  Eastern  being the
surviving  entity  in the  merger.  Eastern  will  become a direct  wholly-owned
subsidiary  of KeySpan and KeySpan  will  register  as a holding  company  under
Section 5 of the Act. An  organizational  chart of the KeySpan  holding  company
system  following  consummation of the Transaction is attached hereto as Exhibit
E-4.

         Upon  consummation  of the  Transaction,  the  common  stockholders  of
Eastern will receive $64.00 in cash, without interest,  for each share of common
stock held  (other than  shares in respect of which  appraisal  rights have been
perfected),  plus an additional $0.006 per share ("Additional  Amount") for each
day the  Transaction has not closed after the later of (a) August 4, 2000 or (b)
ninety days after the New Hampshire Public Utilities  Commission ("NHPUC") gives
final  regulatory  approval to the ENI  Transaction.3  Shares of Eastern  common
stock held by KeySpan,  ACJ or any other wholly owned subsidiary of KeySpan will
be cancelled when the Transaction is consummated.4

         KeySpan anticipates that it will pay approximately $1.7 billion dollars
to acquire  Eastern's  common stock.  KeySpan expects to finance the acquisition
price  by  initially

______________________

3 However,  the  aggregate  Additional  Amount will be reduced by the  aggregate
amount  of any  per  share  increase  in any  dividend  actually  paid  that  is
attributable to any period in which the Additional Amount accrues.

4 In the ENI Transaction, Eastern will acquire all of the issued and outstanding
common stock of EnergyNorth  pursuant to an Agreement and Plan of Reorganization
dated as of July 14, 1999, as amended by Amendment No. 1 dated as of November 4,
1999  (the  "ENI   Merger   Agreement").   As  more  fully   described   in  the
Eastern/EnergyNorth  Application,  the ENI Merger Agreement sets forth the terms
of the  ENI  Transaction.  If,  as is  expected,  the  ENI  Transaction  and the
KeySpan's    acquisition   of   Eastern    through   the    Transaction    close
contemporaneously,  Merger Sub (a  wholly-owned  subsidiary  of Eastern) will be
merged into  EnergyNorth,  with  EnergyNorth as the surviving  corporation and a
direct, wholly-owned subsidiary of Eastern.

                                       3

obtaining  short-term  financing  (e.g.,  bridge loans or commercial  paper) and
replacing a significant portion of such debt with long-term financing as soon as
possible after consummation of the Transaction.

         The Transaction  requires approval by Eastern's  shareholders,  who are
scheduled to vote on the  Transaction at Eastern's  annual meeting to be held on
April 26,  2000.  Eastern  will file with the  Commission  a Proxy  Statement to
solicit the  shareholders'  votes.  Eastern's Proxy Statement is incorporated by
reference as Exhibit C. In addition,  the  Transaction  requires (i) approval of
the NHPUC for the indirect acquisition by KeySpan and ACJ of EnergyNorth through
their  acquisition of Eastern,5 and (ii) clearance by the Antitrust  Division of
the U.S. Department of Justice (the "DOJ") and the Federal Trade Commission (the
"FTC")  under  the  Hart-Scott-Rodino  Antitrust  Improvements  Act of 1976,  as
amended (the "HSR Act"). (See Item 4 below for additional detail regarding these
regulatory approvals.) Apart from the approvals of the Commission under the Act,
the  foregoing  approvals  are the only  regulatory  approvals  required for the
Transaction.  In order to permit timely  consummation of the Transaction and the
realization  of the  substantial  benefits it is  expected  to produce,  KeySpan
requests  that the  Commission  commence  and  proceed  with its  review of this
Application/Declaration as expeditiously as practicable.

                  i.  KeySpan and ACJ


              KeySpan.  KeySpan is a diversified  public utility holding company
currently exempt from registration  under the Act pursuant to Section 3(a)(1) of
the Act6 and Rule 2 of the Commission's  regulations promulgated under the Act.7
On May 28, 1998,  KeySpan

5 If the  NHPUC  does not  approve  the ENI  Transaction,  no  state  regulatory
approvals would be required for the  Transaction.  Therefore,  KeySpan  requests
that if the NHPUC disapproves the ENI Transaction,  the Commission  nevertheless
approve the  Transaction  in the absence of Eastern's  proposed  acquisition  of
EnergyNorth.

became the holding company of three public utility  companies:  Brooklyn Union,8
KeySpan Gas East  Corporation  d/b/a Brooklyn Union of Long Island ("KeySpan Gas
East") and KeySpan Generation LLC ("KeySpan Generation") (collectively, the "New
York  Utilities").9 As further  described below, the New York Utilities  provide
gas or  electric  service  to  customers  located  in New York  City and on Long
Island,  New York.  Together,  Brooklyn  Union and KeySpan  Gas East  distribute
natural gas to approximately  1.6 million retail customers.  KeySpan  Generation
sells  electricity  and capacity at wholesale to one customer  (which is a state
agency that resells the energy at retail).  KeySpan's  non-utility  subsidiaries
are engaged in a variety of  non-utility  energy  related  businesses  which are
described more fully in Item  1.B.1.a(iii)  below.  An  organizational  chart of
KeySpan's current subsidiaries is attached as Exhibit E-2 hereto.

          KeySpan's principal office is at One MetroTech Center,  Brooklyn,  New
York.  KeySpan's  common stock is publicly traded on the New York Stock Exchange
and Pacific Stock Exchange under the symbol "KSE."

          For the year ended  December  31,  1999,  KeySpan  reported  operating
revenues of $3 billion of which $1.8 billion (or approximately 59%) were derived
from  regulated  sales of gas and gas  transportation,  and $861.6  million  (or
approximately  29%) were derived from  electric  operations.  For the year ended
December 31, 1999,  operating income of $ 482.2 million and net income of $258.6
million.  At December 31, 1999, KeySpan had consolidated assets of $6.7 billion,
including  net property and  equipment  of $4.2  billion.  At December 31, 1999,
KeySpan had issued and  outstanding  133.9 million  shares of common stock,  par
value $0.01 per share.  More  detailed  information  concerning  KeySpan and its
subsidiaries  will be contained in KeySpan's  Annual Report on Form 10-K for the
year ended  December 31, 1999, a copy of which KeySpan will file as an amendment
to this  Application/Declaration  as soon as practicable  after it is filed with
the Commission.

          ACJ. ACJ is a wholly owned  subsidiary of KeySpan.  It has been formed
solely  to  serve  as the  acquisition  vehicle  of  Eastern.  At the  time  the
Transaction  is  consummated,  ACJ  will be  merged  out of  existence  with the
surviving entity being Eastern.

8  Brooklyn  Union is an  indirect  subsidiary  of  KeySpan.  Brooklyn  Union is
directly  owned  by  KEC  which,  as  noted  above,  is a  direct,  wholly-owned
subsidiary of KeySpan.  Like KeySpan,  KEC is a utility  holding  company exempt
from  regulation by the  Commission  under the Act (except for 9(a)(2)  thereof)
pursuant to Section 3(a)(1) of the Act and Rule 2 thereunder.

9 In BL Holding,  supra,  the  Commission  approved  the  transactions  by which
KeySpan  (i)  acquired  Long Island  Lighting  Company's  ("LILCO")  non-nuclear
electric generating  facilities,  gas distribution  operations and common plant;
and (ii) acquired KEC, the parent  company of Brooklyn  Union.  KeySpan Gas East
(which owns the former  LILCO gas assets) and KeySpan  Generation  (owner of the
former   LILCO   non-nuclear   generation   assets)  are  direct,   wholly-owned
subsidiaries of KeySpan.

                  ii. The New York Utilities

          The New York Gas  Utilities:  Brooklyn  Union  and  KeySpan  Gas East.
Brooklyn Union and KeySpan Gas East (the "New York Gas  Utilities") are both New
York  corporations  and gas utility  companies  regulated by the New York Public
Service Commission  ("NYPSC") as to rates,  corporate,  financial,  operational,
reliability, safety and other matters, and affiliate transactions.

          Brooklyn Union distributes  natural gas at retail to approximately 1.1
million  residential,  commercial and industrial  customers in the New York City
Boroughs of Brooklyn,  Staten Island and Queens. It has been in the gas business
for over 100 years. Brooklyn Union's properties consist primarily of natural gas
distribution  systems and related  facilities and local offices.  Brooklyn Union
has  approximately  3,909  miles of gas mains  and  1,600,000  Mcf of  liquefied
natural gas ("LNG") storage capacity.

          KeySpan Gas East  distributes  natural gas at retail to  approximately
500,000  customers  located  on Long  Island,  New York in  Nassau  and  Suffolk
counties and the Rockaway Peninsula in Queens County.  Although KeySpan Gas East
has been owned by KeySpan since 1998,  through previous  owners,  it has been in
the gas  business  for over 90 years.  KeySpan  Gas  East's  properties  consist
primarily of natural gas distribution  systems and related  facilities and local
offices. KeySpan Gas East has approximately 6,491 miles of gas mains and 600,000
Mcf of LNG storage capacity.

          Together,  the  facilities  of  Brooklyn  Union and  KeySpan  Gas East
consist of approximately 10,400 miles of gas mains and more than 960,000 service
connections,  all in  Brooklyn,  Staten  Island,  Queens and Nassau and  Suffolk
counties.  In 1999, the New York Gas Utilities had total gas and  transportation
sales of 330.4  billion  cubic feet ("Bcf") of gas. Most of the gas delivered on
the systems of the New York Gas Utilities is derived from sources outside of the
northeast  United States,  primarily the producing areas of Texas and Louisiana.
Gas is  delivered by  interstate  pipelines  pursuant to long-term  contracts at
rates approved by the Federal Energy Regulatory  Commission  ("FERC").  Brooklyn
Union and KeySpan Gas East each  currently have firm  transportation  agreements
with Tennessee Gas Pipeline  Company  ("Tennessee"),  TransContinental  Gas Pipe
Line Company  ("Transco"),  Texas  Eastern  Transmission  Company  ("TETCO") and
Iroquois Gas Transmission System, L.P. ("Iroquois").  Brooklyn Union and KeySpan
Gas East  buy gas from gas  producers  in Texas  and  Louisiana  as well as from
Canadian suppliers.

          KeySpan Generation. KeySpan Generation is a New York limited liability
company which owns and operates approximately 4,032 megawatts ("MW") of electric
generation  capacity located on Long Island ("KeySpan  Generation  Facilities").
The KeySpan Generation  Facilities consist of approximately 53 oil and gas-fired
generating


                                       6
<PAGE>


facilities  located throughout Long Island. All of the capacity from the KeySpan
Generation  Facilities  is sold at wholesale to LIPA pursuant to a 15 year power
supply  agreement  entered  into in June  1997 and  effective  as of May 1998 at
contractual,  cost-of-service  based rates approved by the FERC.10 LIPA provides
electricity  to  approximately  1  million  customers  on Long  Island.  KeySpan
Generation does not own any electric  transmission  or  distribution  facilities
other  than  limited   facilities   necessary  to  interconnect  its  generating
facilities with LIPA's transmission and distribution system.  KeySpan Generation

operating exclusively within  Massachusetts:  Boston Gas Company ("Boston Gas"),
Colonial  Gas  Company  ("Colonial  Gas") and Essex Gas  Company  ("Essex  Gas")
(collectively  referred  to  herein  as  the  "Massachusetts  Utilities").   The
Massachusetts  Utilities are described in greater detail below. Eastern has four
(4) wholly-owned,  material non-utility subsidiaries:  Midland Enterprises, Inc.
("Midland"),  Transgas  Inc.  ("Transgas"),  AMR Data  Corporation  ("AMR")  and
ServicEdge Partners, Inc. (ServicEdge").  As described in more detail below, the
principal  non-utility  activities of Eastern's  subsidiaries  are water barging
activities, including the hauling of fuel and other cargo; transporting by truck
LNG and  propane;  providing  meters and meter  reading  services  to  municipal
utilities; and, providing heating, ventilation and air conditioning services. An
organizational  chart of Eastern and its current subsidiaries is attached hereto
as Exhibit E-3.

          For the year ended December 31, 1998,  Eastern reported gross revenues
of $935,264,000,  of which $667,106,000 (or approximately 71%) were derived from
regulated  sales  of  gas  and  gas   transportation,   operating   earnings  of
$100,405,000,  and earnings  before  extraordinary  items of  $50,828,000.13  At
December 31, 1998, Eastern had consolidated assets of $1,518,370,000,  including
net property and equipment of $975,749,000.  On an unaudited  adjusted basis, to
take into account  financial  results of Colonial Gas, which Eastern acquired in
August 1999, Eastern would have had $1,118,357,000 in gross revenues,  including
$835,000,000,   or  75%  of  the  total,   from  regulated  gas  sales  and  gas
transportation.  At September  30, 1999,  Eastern had  adjusted  combined  total
assets of  $1,908,495,000,  including  adjusted net  property  and  equipment of
$1,269,101,000.14  At December  31,  1999,  Eastern  had issued and  outstanding
27,114,198  shares of common stock, par value $1.00 per share.  Eastern's shares
are listed for  trading on the New York,  Boston and  Pacific  Stock  Exchanges;
however,   they  will  be  delisted  and  cease  to  be  publicly  traded  after
consummation of the Transaction.  More detailed  information  concerning Eastern
and its subsidiaries is contained in the Annual Report on Form 10-K for the year
ended December 31, 1998, a copy of which is incorporated by reference as Exhibit

Mississippi River and their tributaries,  the Gulf Intracoastal Waterway and the
Gulf of Mexico.  Midland has been  operating  on the nation's  inland  waterways
since 1925 and  transports  dry bulk  commodities,  a major  portion of which is
coal.  Through other  subsidiaries,  Midland also performs repair work on marine
equipment,  operates a rail-to-barge coal dumping terminal, a phosphate chemical
fertilizer terminal,  and cargo transfer facilities,  and provides refueling and
barge fleeting services.

          Transgas.  Transgas  (a  direct  subsidiary  of  Colonial  Gas)  is an
unregulated energy trucking company, which provides over-the-road transportation
of  LNG,  propane  and  other  commodities.  Transgas  is the  nation's  largest

          AMR. AMR provides customized metering equipment and performs automated
meter reading services to municipal utilities.

          Together, at December 31, 1998, Eastern's non-utility subsidiaries and
investments constituted approximately 23 % of the consolidated assets of Eastern
and  its  subsidiaries,   11%  of  consolidated  operating  income  and  29%  of
consolidated revenues.

                  c. Energy North and its Subsidiaries

          If the ENI Transaction is consummated,  EnergyNorth  will be a direct,
wholly-owned  subsidiary of Eastern.  EnergyNorth,  a New Hampshire corporation,
owns all of the issued and outstanding  common stock of one gas utility company:
EnergyNorth  Natural Gas,  Inc.  ("ENGI").  EnergyNorth's  material  non-utility
subsidiaries  are  principally  engaged in installing  and servicing  commercial
heating,  ventilation and air conditioning  equipment and distributing  propane.
ENGI  and the  non-utility  subsidiaries  are more  fully  described  below.  An
organizational  chart of EnergyNorth and its  subsidiaries is attached hereto as
Exhibit E-3.

          For the fiscal year ended  September  30, 1999,  EnergyNorth  reported
consolidated  operating revenues of $119,172,000,  of which $76,617,000 (or 64%)
represented  regulated  gas  sales  and  transportation,   operating  income  of
$9,621,000, and net income of $4,537,000. At September 30, 1999, EnergyNorth had

                i.       ENGI

          ENGI  is a  New  Hampshire  corporation  and  a  gas  utility  company
operating  exclusively  within New  Hampshire.  It  distributes  natural  gas to
approximately  73,000  residential,  commercial and  industrial  customers in 28
cities and towns in an area covering approximately 922 square miles and having a
total  population of  approximately  482,000.  ENGI's service area is located in
southern and central New  Hampshire,  with the  exception of the City of Berlin,
which is located in northern New Hampshire.  ENGI owns approximately 1,113 miles
of distribution mains and 700 miles of service connections.  ENGI's service area
in New Hampshire is contiguous to Colonial  Gas's service area in  Massachusetts
and is within 30 to 85 miles of the greater  Boston  area.  As a public  utility
under the laws of the State of New Hampshire,  ENGI is subject to the regulatory
supervision  of the  NHPUC as to gas  sales,  transportation  rates,  securities
issuances and other matters.

          Like the Massachusetts Utilities,  ENGI purchases most of its gas from
sources  outside  New  England   (chiefly  the  producing  areas  of  Texas  and
Louisiana).  All of the pipeline gas  delivered  to ENGI's  principal  system in
southern and central New  Hampshire is  transported  on the  Tennessee  pipeline
system.  ENGI also  purchases gas from Canadian  sources,  which is delivered by
Iroquois to Tennessee for ultimate  delivery to ENGI and by Portland Natural Gas
Transmission System.

                ii.      EnergyNorth's Non-Utility Subsidiaries

          EnergyNorth's principal non-utility subsidiaries are as follows:

          EnergyNorth   Propane,   Inc.   ("ENPI").   ENPI   sells   propane  to
approximately  15,800 customers in more than 150 communities  located  primarily
within a 50-mile radius of Concord, New Hampshire. Propane distribution does not
require a regulatory  franchise in New  Hampshire.  ENPI  operates from separate
headquarters and plant facilities that it owns in Concord, New Hampshire and has
distribution  centers  in  Bedford  and  Gilford,  New  Hampshire.   Propane  is
transported  in bulk supply by trucks to and from ENPI's  distribution  centers.
ENPI owns a 49%  interest in VGS  Propane,  LLC  (VGSP),  a joint  venture  with
Northern  New  England  Gas  Corporation,  which owns the other  51%.  VGSP is a
Vermont   limited   liability   company  which  provides   propane   service  to
approximately  10,000  customers in the state of Vermont.  In August 1999,  ENGI
exercised  an  option  to offer to sell its  interest  in VGSP to  Northern  New
England Gas Corporation. This transaction is expected to close in early 2000.

          ENI Mechanicals,  Inc. ("ENM").  ENM owns all of the outstanding stock
of Northern  Peabody,  Inc.("NPI") and Granite State Plumbing and Heating,  Inc.
("GSPH").  NPI and  GSPH  are  mechanical  contractors  engaged  in the  design,
construction and service of plumbing, heating, ventilation, air conditioning and
process


                                       11
<PAGE>

piping systems. They serve commercial, industrial and institutional customers in
northern  and  central  New  England.   NPI  and  GSPH  operate  from   separate
headquarters and facilities located in Manchester,  New Hampshire and Goffstown,
New Hampshire, respectively.

          Together, at December 31,1999,  EnergyNorth's non-utility subsidiaries
and investments  constituted  approximately  12.7% of the consolidated assets of
EnergyNorth and its subsidiaries, and 36.5% of consolidated revenues.

C.      Description of the Transaction

        1. Background and Negotiations Leading to the Proposed Transaction

          During  the  past  several  years,  Eastern's  board of  trustees  has
regularly reviewed and evaluated  Eastern's  long-term  objectives and strategy,
particularly in light of the energy  industry's  trend toward  deregulation  and
consolidation.  In July 1999,  Eastern's board and management decided to explore
alternatives to enhance shareholder value including a strategic combination with
another company.

          Since its  creation  in 1998,  KeySpan  has  considered  a variety  of
acquisitions and strategic alternatives to enable it to compete more effectively
in the  deregulated  energy  industry.  The  acquisition  of regional gas and/or
electric companies were among the strategic alternatives considered by KeySpan's
management  consistent with KeySpan's  strategic plans and possible  acquisition
candidates were reviewed by KeySpan's board of directors.  The board  encouraged
management's investigation of strategic options including a possible acquisition
of Eastern.

          In September  of 1999,  Eastern's  financial  advisor,  Salomon  Smith
Barney, identified a number of potential strategic partners,  including KeySpan,
and  contacted  them to  determine  their  initial  interests  in  engaging in a
strategic  transaction with Eastern.  On October 13, 1999,  Salomon Smith Barney
reported to Eastern's board that a number of companies,  including KeySpan,  had
submitted non-binding indicative bids. During the month of October,  KeySpan and
other  companies  conducted  due  diligence  reviews of Eastern's  business.  On
November 1, 1999,  Salomon  Smith Barney  reported to the Eastern board that two
companies,  one of which was  KeySpan,  had provided  binding  offers to acquire
Eastern at prices  significantly higher than those previously offered. The board
instructed management to begin negotiations with KeySpan and the other bidder on
a merger agreement.

          Eastern then entered into intensive  negotiations with KeySpan and the
other bidder. On November 3, 1999,  Salomon Smith Barney reported to the Eastern
board that KeySpan and Eastern had reached  agreement on all  outstanding  price
and non-price terms, and that although the price offered by the other bidder was
comparable  to  KeySpan's


                                       12
<PAGE>


proposal,  discussions  with the other  bidder had not  resulted  in  acceptable
resolution of other  important  terms.  Salomon Smith Barney also told the board
that since November 1, 1999,  another  company had submitted a binding offer but
at a price below that  offered by KeySpan and the other  bidder.  On November 4,
1999,  KeySpan  and  Eastern  signed  the  Merger  Agreement.   A  more  fulsome
description  of the events  leading up to the execution of the Merger  Agreement
and the  Transaction is contained in Eastern's  Proxy which is  incorporated  by
reference as Exhibit C hereto.

          The merger of KeySpan and Eastern (including  EnergyNorth) will result
in an integrated  natural gas utility serving  approximately  2.4 million retail
gas customers located in three (3) contiguous states. In addition,  KeySpan will
continue to serve one  wholesale  electric  customer in New York.  The companies
believe that by combining  resources they will be well  positioned to succeed in
an increasingly competitive energy marketplace, particularly in the northeastern
United States.  The companies expect that the Transaction will result in greater
shareholder  value than either  company  could  achieve on its own.  KeySpan and
Eastern believe that the increased size and scope of the combined operation will
improve their  opportunities  for expansion and ability to offer a broad line of
energy products.  Further,  the companies are geographically  compatible because
they are located in contiguous states.  Moreover,  the  characteristics of their
respective service territories are similar,  consisting of both mature,  densely
populated urban centers and suburbs.  These facts provide them with an excellent
ability to share resources and achieve synergies in the increasingly competitive
northeast sector of the country. For example, much of the service territories of
the New York Gas Utilities and the Massachusetts  Utilities have low saturations
of gas heating for  residential  and small  commercial  customers.  The combined
companies,  based on increased size and scope, could utilize common resources to
promote  increased use of natural gas through  oil-to-gas  conversions  and more
effectively compete as suppliers in such developing markets where no gas service
currently exists.

        2.       Merger Agreement

          The Merger  Agreement  provides for Eastern to be merged with and into
ACJ with  Eastern  being  the  surviving  entity.  Eastern  will  then  become a
wholly-owned direct subsidiary of KeySpan and KeySpan will register as a holding
company under Section 5 of the Act. KeySpan will acquire all of Eastern's common
stock in an all cash  transaction.  Shares held by Eastern,  KeySpan,  or any of
KeySpan's  wholly-owned  subsidiaries will be cancelled in the Transaction.  The
closing of the  Transaction  will occur on the second  business day  immediately
following the satisfaction or waiver of the conditions to the Transaction unless
Eastern and KeySpan mutually agree to another time.

          Treatment  of Eastern  Shareholders:  As a result of the  Transaction,
Eastern  shareholders will receive $64.00 in cash,  without  interest,  for each
share of Eastern  common stock,  unless the  shareholder  is entitled to and has
perfected its dissenters' appraisal rights. Eastern shareholders will receive an
additional $0.006 per share  ("Additional  Amount") for each day the Transaction
has not closed  after the later of (a)


                                       13
<PAGE>

August 4, 2000 or (b)  ninety  days  after the New  Hampshire  Public  Utilities
Commission  ("NHPUC") gives final  regulatory  approval to the ENI  Transaction,
though the aggregate  Additional  Amount will be reduced by the aggregate amount
of any per share increase in any dividend  actually paid that is attributable to
any period in which the Additional Amount accrues.

          Closing  Conditions:  The Transaction is subject to customary  closing
conditions,  including  receipt of all required  regulatory  approvals,  such as
approval by the Commission under the Act.

          Tax  Consequences:   The  receipt  of  the  consideration  by  Eastern
shareholders  for  each  share  of  Eastern  common  stock  will  be  a  taxable
transaction  for federal  income tax  purposes.  Each  holder's gain or loss per
share of  Eastern  common  stock  will be equal to the  difference  between  the
holder's tax basis in that particular  share of the Eastern common stock and the
amount of cash received therefor.  Such gain or loss generally will be a capital
gain or loss assuming the Eastern common stock is held as a capital asset at the
time of the Transaction.

          Accounting  Treatment:  The  Transaction  will be  accounted  for as a
purchase for accounting and financial reporting purposes.

D.   Management and Operations of KeySpan Following the Transaction

          Following consummation of the Transaction,  KeySpan will be the direct
parent company of Eastern.  KeySpan's  board of directors will be composed of 15
members.  Robert Catell will remain as the Chief Executive  Officer and Chairman
of the Board of  Directors  of  KeySpan.  J.  Atwood  Ives,  the  current  Chief
Executive  Officer of Eastern,  will be elected to KeySpan's board of directors.
The main corporate  headquarters and principal executive offices of the combined
company  will remain in  Brooklyn,  New York;  however,  Eastern  will  maintain
offices  in the  Boston  area  and  EnergyNorth  will  maintain  offices  in New
Hampshire.

Item 2.  Fees, Commissions and Expenses

          The estimated  fees,  commissions  and expenses in connection with the
proposed Transaction are set forth in Exhibit I hereto.

Item 3.  Applicable Statutory Provisions

          The following sections of the Act and the Commissions rules thereunder
are or may be applicable to the proposed Transaction:

  Section of the Act      Transactions to which Section is or may be applicable
  ------------------      -----------------------------------------------------


  3(a)(1)                 Confirmation that Eastern, EnergyNorth and KEC will
                          continue to be exempt holding companies under the Act


  5                       Registration of KeySpan as a holding company following
                          the consummation of the Transaction

                          operations (i.e., KeySpan Generation) and (ii) the
                          non-utility businesses of KeySpan, Eastern and
                          EnergyNorth


          To the extent  that  other  sections  of the Act and the  Commission's
rules thereunder are or may be applicable to the Transaction,  such sections and
rules should be considered to be set forth in this Item 3.

A.       Approval of the Transaction.

              Section 9(a)(2) provides in pertinent part that:

              Unless the acquisition  has been approved by the Commission  under
              section  10, it shall be  unlawful  . . . for any  person.  . . to
              acquire,  directly  or  indirectly,  any  security  of any  public
              utility company, if such person is an affiliate,  under clause (A)
              of  paragraph 11 of  subsection  (a) of section 2, of such company
              and of any other  public  utility or holding  company,  or will by
              virtue of such acquisition become such an affiliate.

For purposes of section  9(a)(2),  an "affiliate" of a specified  company is any
person that directly or indirectly owns,  controls,  or holds with power to vote
5% or more of the  outstanding  voting  securities  of such  specified  company.
KeySpan  already owns,  directly or


                                       15
<PAGE>

indirectly, 100% of the common stock of the New York Utilities, which are public
utility companies within the meaning of Section 2(a)(5) of the Act. Accordingly,
the  Transaction  requires  approval  pursuant  to  Section  9(a)(2)  because it
contemplates  that KeySpan will  indirectly  acquire 100% of the common stock of
the Massachusetts Utilities and ENGI, each of which are public utility companies
as defined in the Act.

          Section  10 of the Act sets  forth the  statutory  standards  that the
Commission  must consider in evaluating an acquisition  which  requires  Section
9(a)(2) approval.  As demonstrated  below, the Transaction  complies with all of
the applicable provisions of Section 10 of the Act and should be approved by the
Commission. Accordingly,

            o   the Transaction will not tend towards interlocking  relations or
                the  concentration  of control of public utility  companies of a
                kind or to an extent  detrimental to the public  interest or the
                interest of  investors  or  consumers  (Section  10(b)(1) of the
                Act);

            o   the  consideration  to be paid in the  Transaction  is fair  and
                reasonable (Section 10(b)(2) of the Act);

            o   the Transaction will not result in an unduly complicated capital
                structure for the  KeySpan-Eastern  combined system and will not
                be  detrimental  to  the  public  interest  or the  interest  of
                investors  or  consumers  (Section  10(b)(3) of the Act);

            o   the  Transaction  is not  unlawful  under  Section  8 and is not
                detrimental  to the  carrying  out  of  Section  11 of  the  Act
                (Section  10(c)(1) of the Act); o the Transaction  tends towards
                the economical and efficient development of an integrated public
                utility  system  (Section  10(c)(2)  of  the  Act);  and

            o   the  Transaction  will be  consummated  in  compliance  with all
                applicable state laws (Section 10(f) of the Act).

1.       Section 10(b)(1)

         a.   Interlocking Relationships

              By its nature, any merger results in new links between theretofore
unrelated  companies.  However,  these  links are not the types of  interlocking
relationships  targeted  by


                                       16
<PAGE>

Section 10(b)(1),  which was primarily aimed at preventing business combinations
unrelated to operating synergies.18

          The Merger Agreement provides for the board of directors of KeySpan to
be composed of members  from the boards of both  KeySpan  and  Eastern.  This is
necessary to integrate  Eastern fully into the KeySpan system and will therefore
be in the public interest and the interests of investors and consumers.  Forging
such relations is beneficial to the protected  interests  under the Act and thus
is not prohibited by Section  10(b)(1) and is consistent with the composition of
other boards for holding companies registered under the Act.

                b.       Concentration of Control

          Section 10(b)(1) is intended to avoid "an excess of concentration  and
bigness"  while  preserving  the  "opportunities  for  economies  of scale,  the
elimination of duplicate  facilities and  activities,  the sharing of production
capacity and reserves and generally more efficient  operations"  afforded by the
coordination of local utilities into an integrated system.19 In applying Section
10(b)(1) to utility  acquisitions,  the Commission  must  determine  whether the
acquisition  will create "the type of structures and  combinations  at which the
Act was  specifically  directed."20 As discussed below, the Transaction will not
create a "huge,  complex  and  irrational  system,"  but rather  will afford the
opportunity to achieve  economies of scale and efficiencies that are expected to
benefit investors and consumers.21

          Size: If approved,  the KeySpan  system will provide gas  distribution
service to  approximately  2.4 million  residential,  commercial  and industrial
customers  located  in New York,  New  Hampshire  and  Massachusetts  as well as
wholesale electric service to one customer, LIPA, in Nassau and Suffolk counties
and the Rockaway  Peninsula of Queens County,  New York. The combined assets and
revenues of KeySpan and Eastern (including EnergyNorth) will be less than, those
of Dominion  Resources,  Inc.  ("Dominion"),  a combination  registered  holding
company  recently  approved  by  the  Commission.22  Dominion's  acquisition  of
Consolidated Natural Gas Company resulted in a combined gas and electric utility
holding  company system  serving  nearly 4 million retail  customers in five

(5) states,  including  approximately 2 million gas retail customers,  and total
consolidated assets of $29.059 billion and revenues of $8.8 billion.23

          Efficiencies  and  Economies:  As  noted  above,  the  Commission  has
rejected a mechanical size analysis under Section 10(b)(1) in favor of assessing
the  size  of the  resulting  system  with  reference  to the  efficiencies  and
economies  that can be achieved  through the  integration  and  coordination  of
utility   operations.24   The   Commission   has  concluded  that  size  is  not
determinative.  In Centerior Energy Corp.,25 the Commission stated flatly that a
"determination of whether to prohibit  enlargement of a system by acquisition is
to be made on the  basis  of all the  circumstances,  not on the  basis  of size
alone." In addition,  the SEC  Division of  Investment  Management  ("Division")
recommended  in its 1995  report on the  Regulation  of Public  Utility  Holding
Companies  (the "1995  Report")  that the  Commission  approach  its analysis on
merger and  acquisition  transactions  in a flexible  manner  with  emphasis  on
whether the proposed  transaction  would  create an entity  subject to effective
regulation and would be beneficial to  shareholders  and customers as opposed to
focusing on rigid, mechanical tests.26

         By virtue  of the  Transaction,  the  combined  companies  will be in a
position  to  realize  the  substantial  opportunities  to become  an  effective
competitor in a rapidly deregulating and increasingly  competitive energy market
that  neither  KeySpan  nor  Eastern,  acting  alone,  would be in a position to
achieve.  Among other things,  the Transaction is expected to yield  significant
capital  expenditure  and  operating  cost  savings  through   consolidation  of
facilities  and  corporate  and  administrative  functions,  non-gas  purchasing
economies and the  coordinated  management  of gas supply.  The  combination  of
KeySpan and Eastern offers the same type of synergies and efficiencies sought by
the  applicants  (both exempt and  registered  companies) in NIPSCO  Industries,
Inc.,27 TUC Holding  Company,28 WPL Holdings,  Inc.,29 and New Century Energies,
Inc.30 These expected economies and efficiencies from the combined operations of
KeySpan and Eastern are  projected to result in annual net savings of $24 to $29
million,  phased  in over a two  year  period.  Additional  synergies  from  the
combination of the utility operations of both companies are described in greater
detail in Item 3.A.5.ii below.

<PAGE>

          After the Transaction is  consummated,  the retail gas utility company
operations of KeySpan, Eastern and EnergyNorth will continue to be fully subject
to the  jurisdiction  of the  state  regulators  in the  states  in  which  such
operations  are conducted  (i.e.,  New York,  Massachusetts  and New  Hampshire,
respectively). KeySpan's electric utility company, KeySpan Generation, will also
remain subject to the same NYPSC and FERC  regulation  that applied prior to the
merger.  Therefore,  completion of the Transaction will not affect current state
regulation of the combined companies' utility operations.

          Competitive   Effects:   As  the   Commission   stated  in   Northeast
Utilities,31  the "antitrust  ramifications of an acquisition must be considered
in light of the fact that the public utilities are regulated monopolies and that
federal and state administrative agencies regulate the rates charged consumers."
KeySpan and Eastern will file Notification and Report Forms with the DOJ and FTC
pursuant to the HSR Act describing the effects of the Transaction on competition
in the relevant market. It is a condition to the consummation of the Transaction
that the applicable waiting periods under the HSR Act shall have expired or been
terminated.  In the past,  the  Commission has largely relied on, or "watchfully
deferred"  to,32  the   determination   of  other  regulators  with  respect  to
anti-competitive  considerations  and has declined to reconsider  issues of size
and  market  power  that  have  been  considered  by  other  federal   antitrust
regulators.33

          In sum,  for the reasons set forth  above,  the  Transaction  will not
"tend toward  interlocking  relations or the concentration of control" of public
utility companies, of a kind or to the extent detrimental to the public interest
or the  interests of  investors  or  consumers  within the meaning of Section 10
(b)(1),  and the Commission may justifiably  rely on the DOJ/FTC's review of the
Transaction with respect to anti-competitive issues.

                2.       Section 10 (b) (2)


          Section  10(b)(2)  requires the  Commission  to determine  whether the
consideration  to be paid by KeySpan to the holders of Eastern's common stock in
connection  with the  Transaction,  including  all fees  commissions  and  other
remuneration,  is  reasonable  and  whether  it  bears  a fair  relation  to the
investment  in  and  earning  capacity  of the  utility  assets  underlying  the
securities  being  acquired.   The  Commission  has  recognized  that  when  the
consideration to be paid in a proposed transaction is the result of arm's-

length negotiations,  and supported by opinions of financial advisors,  there is
persuasive evidence that Section 10(b)(2) is satisfied.34

          For the  reasons  set  forth  below,  the  Transaction  satisfies  the
requirements of Section 10(b)(2).

                a.       Fairness of Consideration

          The  consideration  for the Transaction is the result of a competitive
process and substantial  arm's-length  negotiations between KeySpan and Eastern.
The negotiations  were preceded by KeySpan's  extensive due diligence,  analysis
and evaluation of the assets, liabilities and business prospects of the combined
companies.  See  "Background  of the Merger" of  Eastern's  Proxy  Statement  in
Exhibit C hereto.

          In  addition,  nationally  recognized  investment  bankers for each of
KeySpan and Eastern reviewed extensive information  concerning the companies and
analyzed   the   Transaction    consideration    employing   several   valuation
methodologies.  KeySpan's financial advisor was JP Morgan Securities,  Inc. ("JP
Morgan")  and it has  provided  a  "fairness"  opinion  to  KeySpan's  Board  of
Directors  with  respect  to the  consideration  to be paid in the  Transaction.
Salomon  Smith  Barney  has  also  rendered  an  opinion  to  Eastern  that  the
Transaction  consideration  is fair from a financial  point of view to Eastern's
common  stockholders.  JP Morgan's opinion is attached hereto as Exhibit G-1 and
Salomon Smith Barney's opinion is incorporated by reference as Exhibit G-2.

                b.       Reasonableness of Fees

          KeySpan  believes  that the overall  fees,  commissions  and  expenses
incurred  and  to be  incurred  in  connection  with  the  Transaction  are  (i)
reasonable  and fair in light of the  size  and  complexity  of the  Transaction
relative  to other  similar  transactions  and the  anticipated  benefits of the
Transaction to the public, investors and consumers,  (ii) consistent with recent
precedent and (iii) meet the standards of Section 10(b)(2).

          As set forth in Item 2 of this  Application/Declaration,  KeySpan  and
Eastern  together expect to incur a combined total of  approximately $ 8 million
in fees,  commission and expenses in connection  with the  Transaction.  KeySpan
believes  that  the  estimated  fees and  expenses  in this  matter  bear a fair
relation to the value of the combined  company and the strategic  benefits to be
achieved  by the  Transaction  and  that  the  fees  and  expenses  are fair and
reasonable in light of the size and complexity of the Transaction.35  Based on a

price for Eastern's common stock at $64.00 per share,  the Transaction  price is
valued at approximately  $1.7 billion.  The total estimated fees and expenses of
$8 million  represent less than 1% of the value of the  consideration to be paid
to the Eastern  shareholders.  This  percentage is consistent  with  percentages
previously approved by the Commission.36

        3.  Section 10 (b) (3)


          Section 10 (b) (3) requires the  Commission  to determine  whether the
Transaction  will  unduly  complicate  KeySpan's  capital  structure  or will be
detrimental  to the public  interest,  the interest of investors or consumers or
the proper functioning of KeySpan's system.

             a.  Capital Structure

          The  Commission  has found that an  acquisition  satisfies the Section
10(b)(3)  analysis where the effect of a proposed  acquisition on the acquirer's
capital  structure  is  negligible  and the equity  position  is at or above the
traditionally  acceptable 30% level prescribed by the Commission.37  Under these
standards,  KeySpan's proposed acquisition of Eastern will not unduly complicate
the capital  structure of the combined system.  Set forth below are summaries of
the  historical  capital  structures of KeySpan,  Eastern and  EnergyNorth as of
December 31, 1999.

          KeySpan's  consolidated equity to total capitalization ratio after the
consummation  of the  Transaction  will exceed the  traditionally  accepted  30%
level.

                b.       Protected Interests

          As set forth more fully in the  discussion of the standards of Section
10(c)(2) in Item 3.A.5.  below,  the Transaction will create  opportunities  for
KeySpan and Eastern to achieve substantial cost savings and synergies,  and will
integrate and improve the efficiency of the KeySpan and Eastern utility systems.
The  Transaction  will  therefore be in the public  interest and the interest of
investors and consumers,  and will not be detrimental to the proper  functioning
of the resulting holding company system.

        4.       Section 10 (c) (1)


          Section 10 (c)(1) of the Act prohibits the  Commission  from approving
an  acquisition  under Section 9(a) of the Act if such  acquisition  is unlawful
under Section 8 of the Act or is  detrimental  to the carrying out of Section 11
of the Act. As demonstrated below, the Transaction is not unlawful under Section
8 nor will it be detrimental to the enforcement of the provisions  under Section
11 of the Act.


                                       22
<PAGE>


        a.       Section 8 Analysis

          Section 8  prohibits  registered  holding  companies  from  acquiring,
owning  interests in, or operating  both a gas and an electric  utility  serving
substantially  the same area if  prohibited  under  state law.  The  Transaction
involves KeySpan's indirect acquisition of the Massachusetts  Utilities and ENGI
which are exclusively gas utility companies.  Accordingly,  the Transaction does
not raise any issue under Section 8 since it does not involve an  acquisition in
which the newly  acquired  gas  companies  will be serving the same areas of any
affiliated electric utility company.38

        b.       Section 11 Analysis

          Section  10(c)(1)  of the  Act  requires  that an  acquisition  not be
detrimental  to carrying out the  provisions  of Section 11. For the reasons set
forth below, the Transaction meets the requirements of Section 10(c)(1).

                i.       Capital and Corporate Structure

          Section  11(a) of the Act  requires  the  Commission  to  examine  the
corporate  structure of registered  holding companies to ensure that unnecessary
complexities   are   eliminated   and  voting  power  is  fairly  and  equitably
distributed. As described above in Item 3.A.3.a of this Application/Declaration,
the  Transaction   will  not  result  in  unnecessary   complexities  or  unfair
distribution of voting powers.

                        Section   11(b)(2) directs the Commission to

                              ensure that the  corporate  structure or continued
                              existence  of any company in the  holding  company
                              system does not unduly or unnecessarily complicate
                              the   structure,   or  unfairly   or   inequitably
                              distribute voting power among security holders, of
                              such holding company  system.  In carrying out the
                              provisions of this paragraph the Commission  shall
                              require each  registered  holding company (and any
                              company in the same  holding  company  system with
                              such  holding  company) to take such action as the
                              Commission  may find  necessary in order that such
                              holding company shall

_________________

38 KeySpan currently owns two gas utility companies  (Brooklyn Union and KeySpan
Gas East) and one electric  utility company (KeySpan  Generation)  which are all
located  in New  York.  In 1998,  KeySpan's  acquisition  of the  companies  was
approved by the Commission,  in BL Holdings,  supra,  and the NYPSC. The service
territories  of the  Massachusetts  Utilities and ENGI will not overlap with the
areas served by KeySpan Generation.


                                       23

                              cease to be a holding company with respect to each
                              of its  subsidiary  companies  which  itself has a
                              subsidiary company which is a holding company.

          After  the  Transaction  is  consummated,  there  will be two tiers of
holding  companies between ENGI and KeySpan (i.e.,  ENGI's parent,  EnergyNorth,
will be a  subsidiary  of  Eastern,  a holding  company,  which will be a direct
subsidiary of KeySpan). This structure raises two issues under Section 11(b)(2):
whether  EnergyNorth's  existence  will  complicate  the  structure of KeySpan's
holding company system after the Transaction is  consummated;  and,  whether the
Transaction will result in an unfair or inequitable distribution of voting power
among the security  holders of the holding company system.  As discussed  below,
EnergyNorth's  existence does not raise the complexities  Section 11(b)(2) seeks
to address.  Moreover, as soon as reasonably  practicable after the consummation
of the Transaction,  KeySpan intends to eliminate EnergyNorth as an intermediary
holding company so that ENGI will become a direct utility  subsidary  company of
Eastern.

          EnergyNorth's  continued  existence  is  necessary  to ensure a smooth
transition  toward  the  coordination  of ENGI's  operations  with  those of the
Massachusetts  Utilities and the New York Gas  Utilities.  Because  KeySpan will
indirectly own all of the outstanding  common stock of Eastern and  EnergyNorth,
the continued  existence of EnergyNorth  during a transitional  period raises no
concern over any undue  complexities in the holding company  structure or a risk
of unfair or inequitable distribution of voting power within the holding company
system.39  Therefore,  KeySpan requests that the Commission permit the continued
existence of EnergyNorth following the consummation of the Transaction.40

                ii.      Integrated Public Utility Holding Company System

          Section  11(b)(1)  generally  requires a  registered  holding  company
system to limit its operations "to a single  integrated  public utility  system,
and to such other  businesses  as are  reasonably  incidental,  or  economically
necessary or  appropriate  to the operation of such  integrated  public  utility
system."  Ordinarily,  the single  system can  provide  either  electric  or

39 KeySpan will issue debt to acquire  Eastern and, like  acquisitions  recently
approved by the Commission which resulted in newly registered holding companies,
such debt is consistent with that permitted under Section  7(c)(2)(A) of the Act

40 The  Commission  has the ability to exercise  its  reasonable  discretion  to
permit a "great grandparent" holding company structure when the specifics of the
transaction do not raise the concerns  Section 11(b)(2) was intended to address.
See, e.g.,  West Penn Railways Co.,  Holding Co. Act Release No. 953 (January 3,
1938) (expressly  authorizing the continued existence of an intermediate holding
company);  West Texas  Utilities Co.,  Holding Co. Act Release No. 4068 (January

gas service,  however,  Section  11(b)(1)  (A-C) of the Act (the "ABC  Clauses")
provides  an  exception  to  the  "single  system"  requirement  and  permits  a
registered  holding  company  to own one or more  additional  integrated  public
utility systems (e.g., both gas and electric) if the criteria of the ABC Clauses
are met.

          As described more fully in Item 3.A.5.i below,  the principal  utility
system of the combined companies,  comprised of the gas operations  conducted by
Brooklyn  Union and KeySpan Gas East and Eastern's  gas  operations  (i.e.,  the
Massachusetts  Utilities  and  ENGI),  satisfy  the  requirements  for a  single
integrated  gas utility  system.  Moreover,  as set forth  below,  retention  is
permissible  of (a) KeySpan  Generation  because it qualifies  as an  additional
electric  system under the ABC Clauses,  and (b) the  non-utility  businesses of
KeySpan,  Eastern and EnergyNorth  because they satisfy  standards for retention
under Section 11(b)(1) of the Act.

                                (1)      Retention of Electric Operations:


          The ABC  Clauses  under  Section  11 (b)(1)  permit the  retention  of
additional  integrated  public-utility  systems  if  the  Commission  finds  the
following:

                    (a) each of the additional  systems cannot be operated as an
                    independent system without the loss of substantial economies
                    which can be  secured  by the  retention  of control by such
                    holding company of such system;

                    (b) all of the additional  systems are located in one state,
                    in adjoining states or in a contiguous foreign country; and

                    (c) the  continued  combination  of such  systems  is not so
                    large  (considering  the  state  of the art and the  area or
                    region  affected) as to impair the  advantages  of localized
                    management,  efficient  operation  or the  effectiveness  of
                    operation.

          Historically,  the  Commission  considered  the  question of whether a
registered  holding  company could retain a separate system by applying a strict
standard  that  required a showing  of a loss of  substantial  economies  before
retention  would  be  permitted.41   Under  the  Commission's   previous  narrow
interpretation  of  Section  11(b)(1)(A),  when  considering  whether  to permit
primarily  electric  utility  holding  companies  to keep their gas assets,  the
Commission,  as a guide to determining  whether lost economies are  substantial,
gave  consideration to four ratios which measure the projected loss of economies
as a percentage

of: (1) total gas operating  revenues;  (2) total gas expense or "operating  gas
revenue  deductions";  (3) gross gas  income;  and (4) net gas income or net gas
utility  operating  income.  Although  the  Commission  has  declined  to draw a
bright-line numerical test under Section 11(b)(1)(A), it has indicated that cost
increases resulting in a 6.78% loss of operating  revenues,  a 9.72% increase in
operating revenue deductions, a 25.44% loss of gross income and a 42.46% loss of
net income would afford an  "impressive  basis for finding a loss of substantial
economies."42

          However,  in its  1995  Report,  the  Division  recommended  that  the
Commission   "liberalize   its   interpretation   of  the  `A-B-C'   clauses."43
Accordingly,  the Commission has explicitly  rejected a rigid  interpretation of
the  requirements of the ABC Clauses in a number of recent decisions in which it
has approved newly formed combined utility registered holding company systems.44
In these cases,  the Commission  has found that,  due to the  convergence of the
energy and gas industries,  retention of an additional system is desirable where
separation  of the gas  business  from the  electric  business  could  cause the
divested  entities  to be  weaker  competitors.45  Thus,  even a  small  loss of
economies  could be harmful to each entity's  competitive  position if they were
required to separate.46

          The  Commission's  review  of the  Transaction  and its  retention  of
KeySpan  Generation  under the ABC Clauses should be evaluated based on its more
recent  precedent  and policy  advocating a more  flexible  approach to combined
electric and gas systems.  If KeySpan  Generation  were divested,  KeySpan would
lose (i) its ability to economically  meet its current power supply  obligations
to LIPA; and (ii) the potential  competitive benefits of a combined electric and
gas company in the  emerging  converged  energy  market  because the loss of its
electric assets would hamper its future ability to provide customers with a full
range of energy options.

          Nevertheless,  even under the Commission's  more stringent  historical
analysis,  KeySpan  Generation  would  experience  significant lost economies if
operated on a stand

Conectiv,  New Century and WPL Holdings, the Commission permitted the applicants
to retain  their  additional  gas systems  because the ratios set forth in their
severance studies exceeded the Commission guidelines.

alone basis  without any increase in benefits to  consumers.47  Attached to this
Application/Declaration  as Exhibit J is an "Analysis of the Economic  Impact of
Divestiture  of the Electric  Operations of KeySpan  Generation  LLC"  hereafter
referred to as the Retention  Study. As demonstrated in the Retention  Study, if
KeySpan  Generation  were divested and forced to operate on a stand alone basis,
it would result total lost economies of $17.4 million,  increased  operation and
maintenance  expenses  of  16.4%,  a 60.8%  loss of gross  income  (pre-tax  net
income),  and a 48.3% loss of net electric income. Here, the lost economies that
would be experienced if the electric  facilities  were to be operated on a stand
alone   basis   exceed  the   Commission's   guidelines   even  under  a  narrow
interpretation of the Section 11(b)(1)(A).

          Clause (B) of Section 11(b)(1) is met because the electric  operations
of KeySpan  Generation are located in one state (New York).  KeySpan  Generation
will be in the  same  state  as the New York  Gas  Utilities  which  are part of
KeySpan's proposed principal integrated gas system.

          With respect to clause (C) of Section 11(b)(1),  KeySpan  Generation's
continued  electric  operations under KeySpan are not so large  (considering the
state of art and the area or region  affected)  as to impair the  advantages  of
localized  management,  efficient  operation or the effectiveness of regulation.
KeySpan  Generation's  electric  system is confined to a  relatively  small area
(i.e., Long Island).  Moreover,  management  currently is, and will remain after
the Transaction,  in the New York city metropolitan area, thereby preserving the
advantages  of  localized  management.  The  Transaction  will have no impact on
effective  regulation  because  KeySpan  Generation  will remain  subject to the
jurisdiction  of the  FERC and the  NYPSC.  Finally,  as  discussed  above,  the
electric  operations enjoy  substantial  economies as part of the KeySpan system
and should realize additional economies after the Transaction.

                        iii.     Retention of Non-Utility Businesses

          Section  11(b)(1)  permits  a  registered  holding  company  to retain
non-utility   businesses   which  are  reasonably   incidental  or  economically
necessary,  or appropriate and not detrimental to the proper  functioning of the
holding company systems.  Although the Commission has traditionally  interpreted
this provision to require an operating or

47 By way of  background,  KeySpan Gas East and KeySpan  Generation  have a long
historical  relationship  because their gas and electric  assets were originally
owned and operated by LILCO on an integrated  basis.  When KeySpan  acquired the
assets in 1998, they were  transferred into the separate  companies.  Ten out of
eleven of KeySpan  Generation's  steam generating  plants are capable of burning
gas to generate  electricity.  In BL Holdings,  supra,  the Commission  approved
KeySpan's  acquisition  of KeySpan Gas East and KeySpan  Generation and found de
facto integration of the separate gas and electric systems based on factors such
as  their  shared   physical   interconnections   and  common  gas  sources  and
administrative coordination.

functional relationship48 between the non-utility activity and the system's core
non-utility  business,  in its release  promulgating  Rule 58,49 the  Commission
stated  that it "has  sought to  respond  to  developments  in the  industry  by
expanding its concept of a functional relationship." The Commission concluded in
the Rule 58 Release "that various considerations,  including developments in the
industry,   the  Commission's   familiarity  with  the  particular   non-utility
activities at issue, the absence of significant risks inherent in the particular
venture,  the specific  protections  provided for  consumers  and the absence of
objections  by the relevant  state  regulators,  made it  unnecessary  to adhere
rigidly to the types of administrative  measures" used in the past. Furthermore,
in the 1995 Report,  the  Commission's  staff  recommended  that the  Commission
replace the use of bright-line  limitations  with a more flexible  standard that
would take into  account the risks  inherent in the  particular  venture and the
specific protections provided for consumers.50

          Registered  holding companies and their  subsidiaries are permitted to
invest in energy  related  companies,  as defined  under the  Commission's  Rule
58(b)(1),  without  prior  Commission  approval  under the Act if the  aggregate
investment in all such energy  related  companies does not exceed the greater of
$50 million or 15% of the consolidated  capitalization of the registered holding
company.  However,  the Commission has disregarded existing investments in these
types of activities,  for purposes of  calculating  the dollar  limitation  upon
investments in energy related  companies,  which were made by a holding  company
prior to its registration under the Act.51

              Rule 58(b)(2) permits gas registered  holding  companies to invest
in gas  related  companies  without the  Commission's  prior  approval  and such
activities are not subject to any dollar  limitation.  A gas registered  holding
company,  for  purposes  of Rule 58, is  defined  as a holding  company  that is
registered  solely by reason of  ownership of voting  securities  of gas utility
companies or a subsidiary  company thereof.52 A gas related company is a company
that derives, or will derive, substantially all of its revenues from one or more

1998); see also Ameren Corporation,  Holding Co. Act Release No. 26809 (December
39, 1997). The Commission reached this conclusion in previous orders because the
companies  involved in the mergers  were not  previously  subject to the Section
11(b)(1) restrictions on non-utility  investments which apply only to registered
holding companies.

52 Because  KeySpan will  register  solely by reason of its  acquisition  of gas
utility companies (i.e., the Massachusetts Utilities and ENGI), it qualifies for
the exemptions related to ownership of gas related companies under Rule 58.

activities  permitted  under the Gas Related  Activities  Act  ("GRAA").53  Rule
58(b)(2)(i)  and  Section  2(a) of the GRAA apply to  activities  related to the
transportation and storage of natural gas; Rule 58(b)(2)(ii) and Section 2(b) of
the GRAA apply to  activities  related to the supply of natural  gas.  The "GRAA
does not impose any geographic  boundaries  within which a gas registered system
may engage in the listed  activities."54  Thus, the GRAA permits  registered gas
utility holding  companies to own companies engaged in international gas related
activities.55

          KeySpan is presently a holding company exempt from registration  under
the Act, as are Eastern and EnergyNorth.  As exempt holding companies,  each has
been free to  invest  in a variety  of  non-utility  businesses  and  activities
without the need to obtain prior  Commission  approval under Section 9(a) of the
Act. The companies'  non-utility  investments have been successful overall, have
resulted in tangible  benefits to their respective  shareholders,  and have been
undertaken in compliance with applicable  state laws and regulations in a manner
to minimize risks to the  ratepayers of their  respective  utilities.  Except as
discussed in Item  3.b.iii.4  below,  the  non-utility  business  interests that
KeySpan  will  hold,  directly  or  indirectly,  after the  consummation  of the
Transaction  meet the Commission's  standards for retention.  The following is a
description  of  the  specific  bases  under  which  the  existing   non-utility
investments  of KeySpan,  Eastern and  EnergyNorth  may be retained  pursuant to
Section 11(b)(1).56

          The Commission has authorized  registered holding companies to own
businesses involved in the exploration,  ownership,  development and acquisition
of  natural  gas and oil  properties.64  Additionally,  the  activities  of such
companies which relate to natural gas, are gas related  activities under Section
2 of the GRAA. Since the following companies are substantially  similar to those

                Midland

          Eastern's predominant non-utility  subsidiary,  Midland,82 is engaged,
through wholly owned subsidiaries, in activities which KeySpan recognizes do not
satisfy the standard for retention by a registered gas utility  holding  company
under Section 11(b)(1) of the Act.  Midland's  activities  primarily  consist of
operating a fleet of towboats,  tugboats and barges which transport a variety of
commodities  including stone, grain, sand, scrap, coal, steel, coke;  performing
repair  work on  marine  equipment;  operating  coal  dumping  and  other  river
terminals and a ship loading terminal for phosphate rock; and provide  refueling
and  barge  fleeting  services.83  KeySpan  requests  that  any  order  that the
Commission  issues which approves the Transaction but requires KeySpan to divest
of Midland  pursuant to Section  11(b)(1) of the Act permits KeySpan to take the
appropriate  actions to effect the sale of all of its interests in Midland,  its
subsidiaries   and  assets,   within  three  years  after  the   Transaction  is
consummated.

          5. Section 10 (c) (2)

          Section  10(c)(2) of the Act  requires the  Commission  to find that a
proposed  transaction  will serve the public  interest  by tending  towards  the
economical and efficient  development of an integrated public utility system. An
"integrated public utility system" is defined in Section 2(a)(29) to mean:

          (B) As applied to gas utility companies, a system consisting of one or
          more gas  utility  companies  which are so located  and  related  that
          substantial  economies  may be effected by being  operated as a single
          coordinated  system  confined  in its  operations  to a single area or
          region, in one or more States, not so large as to impair  (considering
          the state of the art and the area or region  affected) the  advantages
          of

______________________

82 Midland files annual and other periodic reports with the Commission  pursuant
to Section 12(g) of the Securities Exchange Act of 1934. See File No. 2-39895.

83 The  principal  operations of Midland  (specifically,  ORCO) were acquired by
Eastern  (then  known as Eastern Gas and Fuel  Associates)  in 1961 as part of a
business   combination  in  which  the  former  shareholders  of  ORCO  acquired
approximately  15% of Eastern's  common stock in exchange for the stock of ORCO.
"New" Midland was  subsequently  formed by Eastern to serve as a holding company
for ORCO and other related entities. Although certain aspects of the transaction
were approved by the Commission,  the Commission  specifically noted its lack of
jurisdiction over Eastern's acquisition of the stock of ORCO inasmuch as Eastern
had been granted an exemption  pursuant to Section 3(a)(1) of the Act some years
earlier. See Midland Enterprises Inc., et al., Holding Co. Act Release No. 14486
(July  25,  1961).  Thus,  the  Commission  has not  previously  considered  the
affiliation  between Eastern and Midland in light of the retention  standards of
Section  11(b)(1),  which,  by its terms,  applies  only to  registered  holding
companies.


                                       41

          localized  management,  efficient operation,  and the effectiveness of
          regulation,  Provided, that gas utility companies deriving natural gas
          from a common  source of supply  may be  deemed  to be  included  in a
          single area or region.

          For the  reasons  stated  below,  the  Transaction  meets the  Section
10(c)(2) requirements.  The gas utility operations of KeySpan and Eastern, after
the closing of the Transaction, will constitute a coordinated gas utility system
within the meaning of Section 2(a)(29).84 Through the Transaction, the companies
will produce qualitative and quantitative  economies and efficiencies and become
an entity well suited to compete effectively.

                i.       Single Area or Region Requirement

          The  operations  of the  combined  gas  systems  of the New  York  Gas
Utilities,  the  Massachusetts  Utilities and ENGI will be confined to "a single
area or region" as required by Section  2(a)(29)(B).  The combined  systems will
operate  in the  three  contiguous  states of New  York,  Massachusetts  and New
Hampshire.  The  distance  from the New York  City  area to  Boston is about 200
miles. By contrast,  other  registered  public utility holding company  systems,
such as Columbia and CNG, which both extend from  Tidewater  Virginia to western
Ohio, are spread over a much larger area. Consolidated Natural Gas, et. al, HCAR
25040 (2/14/90); The Columbia Gas System, Inc., HCAR #22155 (8/20/81). Moreover,
utilities  in the New York and Boston areas share the same  challenges  of being
distant  from  gas  producing  areas  and  near  the  end  of the  nation's  gas
transportation  systems. New York,  Massachusetts and southern New Hampshire are
part of the Northeast  United States,  an area generally  recognized as a single
region of the country, particularly in the energy industry.85

          In addition,  the Section 2(a)(29)(B)  requirement that a combined gas
system  confine  its  operations  to "a  single  area or  region"  may be deemed
satisfied when gas utilities  derive natural gas from a common source of supply.
In a number  of  recent  decisions,  the  Commission  has  determined  that even
acquisitions  involving  geographically

_____________________

84 As discussed in Item 3.A.4.b.(ii) above,  KeySpan's retention of the electric
operations  of KeySpan  Generation  is  permissible  under the ABC clauses as an
additional system and will tend toward the economic and efficient development of
KeySpan's   proposed   holding  company  system  through  shared  economies  and
efficiencies.

85 The Commission  has  recognized in certain  contexts that it is reasonable to
consider New York and New England  together a single region of the country.  See
Eastern Utilities Associates,  Holding Co. Act Release No. 26232, 1995 SEC LEXIS
395 (February 15, 1995) ; Eastern Utilities Associates,  Holding Co. Act Release
No.  25636,  1992 SEC LEXIS 2343  (September  17,  1992);  Northeast  Utilities,
Holding  Co. Act Release No.  Release No.  25114,  1990 SEC LEXIS 2720 (July 27,
1990).


                                       42

dispersed gas systems meet the "single area or region" statutory test when those
systems acquire gas from common sources.86

          The  Commission  has found that "[t]he  concept of a `common source of
supply' is susceptible of a different understanding today than in 1935, when the
`single area or region' was generally  defined in terms of the pipeline delivery
points (i.e., the city-gate) where the local  distribution  companies  purchased
their  gas."87 The  Commission's  inquiry now focuses  upon whether the proposed
combined utilities purchase  substantial  quantities of gas produced in the same
supply  basins and upon  whether  there is  sufficient  transportation  capacity
available to assure  economical  and reliable  delivery.88  In this regard,  the
Commission also looks at whether the systems are served by common pipelines, and
has  recognized  that,  in today's  gas market,  purchases  of gas from the same
basins are facilitated by the  development of market  centers,  hubs and pooling
points.89

          The gas  portfolios of the New York Gas Utilities,  the  Massachusetts
Utilities and ENGI substantially  overlap with respect to sources of supply. All
of the utilities derive large portions of their total gas requirements  from two
primary areas: the New York Gas Utilities,  the Massachusetts Utilities and ENGI
derive 63.2%,  91.1% and 90%,  respectively,  from the supply basins in the U.S.
Gulf  Coast.90 The New York Gas Utilities  purchase  36.7% of their gas supplies
from the Western Canada  Sedimentary Basin, which is also a source of supply for
the  Massachusetts  Utilities (3.6%) and ENGI (8.8%).  KeySpan and Eastern's gas
utilities also utilize  common gas  transportation  pipelines.  The New York Gas
Utilities,  the  Massachusetts  Utilities and ENGI hold significant  portions of
their  firm  transportation  capacity  on  Tennessee  (20.2%,  24.4% and  93.8%,
respectively),  Iroquois (10.1%, 8.9% and 5.0%,  respectively) and Duke Energy's
pipelines, TETCO and Algonquin (the New York Gas Utilities hold 23% on TETCO and
the  Massachusetts  Utilities  hold  25.8% on  TETCO  and  35.1% on  Algonquin).
Furthermore,  the New York Utilities,  the Massachusetts  Utilities and ENGI all
have  access  to the  Leidy,  Pennsylvania  trading  hub at a point at which the
pipelines on which they hold transportation capacity intersect.

          The  commonality  of supply  sources and  transporters  of KeySpan and
Eastern's gas utilities is comparable to that found to constitute "common source
of supply" in recent  Commission cases. For example,  in NIPSCO,  the Commission
found that the two

proposed  combined gas systems  derived gas from common supply  sources based on
the facts that (i) the NIPSCO and Bay State gas utilities derived, respectively,
89% and 40% of their total gas  requirements  from the same Texas and  Louisiana
supply  basins  and  (ii)  each  system  had  contracted  with  Tennessee  for a
significant  portion (36% and 27%,  respectively)  of total firm  transportation
capacity.  The  Commission  also  observed  that while the  systems had only one
pipeline in common,  pipelines  on which they held  capacity  intersect  at, and
form,  industry-recognized  trading hubs. Moreover, in NIPSCO, the gas utilities
were located in  non-contiguous  states of Indiana and  Massachusetts  while the
proposed combined gas companies in Sempra were in California and North Carolina.
91 In  contrast,  the  systems  proposed  to be  combined  here are  located  in
contiguous states in a generally  recognized region. For that reason and because
of the substantial  commonality of supply and  transportation  sources among the
New York Gas Utilities, the Massachusetts Utilities and ENGI, the combination of
KeySpan's  and  Eastern's  gas  utilities  satisfies the "single area or region"
requirement under Section 2(a)(29)(B).

                ii.      Economies and Efficiencies

          The   combined   operations   of  KeySpan  and  Eastern  will  achieve
substantial   economies.   Although  many  of  the  anticipated   economies  and
efficiencies will be fully realizable only in the longer term, they are properly
considered in determining  that the Section  10(c)(2)  criteria have been met.92
The Commission has also recognized that while some potential  benefits cannot be
precisely estimated, they are nevertheless entitled to consideration.93

                                (1)      Coordination of Gas Operations

          Coordination  of the  operations of the gas supply  departments of the
New  York  Gas  Utilities  and the  Massachusetts  Utilities  (and  ENGI)  will,
consistent with the limitations  imposed on the New York Gas Utilities by reason
of the "two  county"  rule of

______________________

91 The Commission  specifically  ruled that the distances between the systems to
be  combined  in those  cases did not  contravene  the policy of the Act against
"scatteration" - the ownership of widely dispersed  utility  properties which do
not lend themselves to efficient operation - noting that the acquiring system is
required to maintain an integrated gas system. NIPSCO at WL 61423, *8; Sempra at
WL 38638, *6. Here, as noted above, the gas systems of KeySpan, Eastern and ENGI
are  located  in the  contiguous  states  of New  York,  Massachusetts  and  New
Hampshire.  Because  they are not widely  dispersed  like in NIPSCO and  Sempra,
there is no possibility they the combination  could contravene the policy of the
Act against "scatteration."

Section  103 of the  Internal  Revenue  Code,  be  achieved  through  joint  and
coordinated  management of the gas supply  function for all of the gas utilities
to be owned by the combined  companies.  By 2002, all of the gas assets owned by
the New York Gas Utilities and the Massachusetts Utilities (including ENGI) will
be operated and managed  jointly by a single entity and a joint strategy will be
pursued for the gas supply portfolios of both utility systems  (including ENGI).
For the period ending October 31, 2002, each of the  Massachusetts  Utilities is
party to an asset  management  agreement with El Paso Energy  Marketing  Company
("El Paso") pursuant to which the majority of the  Massachusetts  Utilities' gas
supply  assets  upstream  of the city gate are  managed by El Paso.  The El Paso
asset  management  agreement  will be amended to cover the gas supply  assets of
ENGI as well. The gas asset  management  arrangements  which currently cover the
gas supply assets of the New York Gas Utilities are being replaced with a single
arrangement that will terminate March 31, 2002.  Following  termination of those
agreements,  there  will be  significant  opportunities  for the two  systems to
realize substantial synergies. The gas supply portfolios (including firm supply,
transportation  and  storage  assets)  of the New  York  Gas  Utilities  and the
Massachusetts   Utilities   (including  ENGI)  will  be  jointly  managed  in  a
coordinated way, thereby providing a greater degree of diversity and operational
flexibility.  This will enable the two systems to achieve  greater  efficiencies
through asset  optimization  in order to enhance  opportunities  to minimize gas
costs as well as to generate  additional value. For example,  as a result of the
increased diversity of the combined portfolios, the combined companies will have
increased price arbitrage opportunities to maximize revenues.

          In addition,  the joint  company will be able to maximize the benefits
of  deregulation.  Depending on how the various state  unbundled  transportation
programs  evolve,  the combined  companies  will have greater  opportunities  to
maximize  efficiencies to reduce gas costs as they decontract  assets previously
contracted for to provide  bundled sales  service.  Also,  the  flexibility  and
reliability  of the unbundled  transportation  and  balancing  services that the
combined companies provide to the firm transportation  customers will be further
enhanced by the increased  diversity and operational  flexibility offered by the
combined  portfolios.  Furthermore,  there will be new  opportunities to provide
products and services in the deregulated market that will yield additional value
through the combined utility assets.

          Even in the interim period between consummation of the Transaction and
2002, when the asset management agreements terminate, there may be opportunities
to achieve modest  synergies to generate value and realize gas cost savings with
those gas assets that are excluded from the two asset management agreements.

          Finally,  both  the New  York  Gas  Utilities  and  the  Massachusetts
Utilities  rely on the  Altra Gas  Management  System,  using the same  products
acquired from the same vendor.  The systems  currently  employed by the New York
Gas Utilities and the Massachusetts Utilities will be integrated,  enhancing the
ability to coordinate  the gas supply  functions of all of the utilities of both
companies (including ENGI).

                        (2)      Other Efficiencies and Economies

          Based on preliminary estimates,  the Transaction is expected to result
in annual savings of $24-29 million,  phased in over a two year period.  This is
equal to 2.2 to 2.8% of annual gas utility operating  expenses.  The bulk of the
savings  would occur as a result of employee  reductions,  which are expected to
result in savings of approximately  $15 million as a result of the consolidation
of corporate and  administrative  functions and the elimination of approximately
200 full time positions.  Another $2-4 million would be saved as a result of the
consolidation of corporate  facilities,  including control rooms and the IT data
center.  A net savings of $4 to $7 million would be  experienced  as a result of
reductions  in  duplicate  functions  including  shareholder  services,  outside
director   expenses,   and   services  of  legal,   financial   and   investment
professionals,  insurance,  information services, etc. Approximately $200,000 is
expected to be saved in non-fuel  purchasing  economies as a result of increased
purchasing  power.  In addition,  reductions  in employee  benefit costs such as
pensions,  post-employment benefits and other employee benefit related economies
are expected to generate between $2.5 and $3 million in savings.

          In addition,  the  Transaction  would produce  approximately  $5 to $7
million  in avoided  development  costs for  information  systems  and  software
applications.  The  information  technology  in use at  KeySpan  and  Eastern is
largely  compatible.  There are  opportunities in the short run to consolidate a
data center as well as to  consolidate  the  applications  portfolios of the two
systems. In the long run, there is a potential for significant staff reductions.

          KeySpan and Eastern are also in the process of identifying  additional
opportunities  for the merged  companies  to achieve  additional  administrative
savings in such areas as accounting,  tax, purchasing,  legal,  planning,  human
resources, information services, financial services and regulatory relations.

               iii.     Size and Local Requirements

          As demonstrated  above,  the combined system will not be "so large" as
to contravene  the  statutory  standards  with respect to localized  management,
efficient  operations and the effectiveness of regulation.  Each of the KeySpan,
Eastern and ENGI utilities will maintain  offices and  operational  functions in
the state in which it  provides  services.  There  will be a  substantial  local
executive presence in Boston,  including several officers of Boston Gas who will
be retained to manage the  operations of the  Massachusetts  Utilities and ENGI.
The  Transaction  will result in  substantial  economies  and  efficiencies,  as
discussed  immediately  above.  Finally,  each of the New  York  Utilities,  the
Massachusetts  Utilities  and ENGI will  remain  subject  to  regulation  by its
respective state regulators in New York, Massachusetts and New Hampshire.


                                       46
<PAGE>

          6.   Section 10 (f)


          Section 10 (f) prohibits the Commission from approving the Transaction
unless the Commission is satisfied that the consummation of the Transaction will
comply with applicable  state laws. As described in Item 4 of this  Application,
and as evidenced by the application before the NHPUC,  KeySpan intends to comply
with all applicable state laws related to the proposed Transaction.

B.       Section 3(a)(1) Holding Company Exemption

          After  completion  of  the   Transaction,   KeySpan  will  have  three
subsidiaries  which  will  be  holding  companies.  KeySpan  requests  that  the
Commission  confirm that they will each continue to be exempt holding  companies
under Section 3(a)(1) of the Act. These exemptions, however, will have no effect
on the status of these  companies as  "subsidiary  companies" of KeySpan once it
registers as a holding company.

          KEC will  continue to qualify for a Section  3(a)(1)  exemption  after
consummation of the Transaction.  It is a New York corporation and will continue
to directly own all of the common stock of Brooklyn  Union,  which is also a New
York corporation operating exclusively in New York.

          Eastern  and  EnergyNorth   have  each  requested  a  Section  3(a)(1)
exemption in the Eastern/EnergyNorth  Application.  KeySpan requests that to the
extent the Commission grants them such exemptions in that proceeding, it confirm
that those exemptions will continue after the Transaction.

Item 4.  Regulatory Approvals

          Set forth below is a summary of the regulatory  approvals that KeySpan
and Eastern have obtained or expect to obtain in connection with the Transaction
in addition to the Commission approvals required under the Act.

A.       Antitrust

          The HSR Act and the  rules and  regulations  thereunder  provide  that
certain  transactions  (including the Transaction) may not be consummated  until
certain  information has been submitted to the DOJ and FTC and specified HSR Act
waiting period requirements have been satisfied. KeySpan and Eastern will submit
Notification  and Report Forms and all required  information  to the DOJ and FTC
and the Transaction will


                                       47
<PAGE>


not be consummated  unless the applicable waiting period has expired or has been
terminated.  Eastern and EnergyNorth  will also submit  Notification  and Report
Forms and all  required  information  to the DOJ and FTC with respect to the ENI
Transaction which will not be consummated  unless the applicable  waiting period
has expired or has been terminated.

          The  expiration  of the HSR Act waiting  period does not  preclude the
Antitrust  Division of the FTC from  challenging  the  Transaction  on antitrust
grounds; however, KeySpan believes that the Transaction will not violate Federal
antitrust laws. If the Transaction is not consummated within twelve months after
the expiration or earlier termination of the initial HSR waiting period, KeySpan
and Eastern would be required to submit new  information to the DOJ and FTC, and
a new HSR waiting  period would have to expire or be earlier  terminated  before
the Transaction could be consummated.

B.       State Public Utility Regulation

         New Hampshire

          ENGI, EnergyNorth's wholly-owned subsidiary, is a New Hampshire public
utility subject to the jurisdiction of the NHPUC. Under the applicable statutes,
the  NHPUC  must  determine  that  Eastern's  acquisition  of  EnergyNorth,  and
KeySpan's indirect acquisition through its acquisition of Eastern, will not have
an adverse  affect on the rates,  terms,  service,  or operations of ENGI and is
lawful, proper and in the public interest. On December 3, 1999, KeySpan, Eastern
and EnergyNorth filed a joint application with the NHPUC which requests approval
for Eastern's direct, and KeySpan's  indirect,  acquisition of EnergyNorth.  See
Exhibit D-1.

          New York

          The New York  Utilities,  wholly-owned  subsidiaries  of KeySpan,  are
subject  to  the  NYPSC's  jurisdiction.  The  NYPSC  does  not  have  statutory
jurisdiction over the Transaction.94

94 KeySpan notes that immediately after the Transaction was publicly  announced,
it informed high level  officials at the NYPSC about the  Transaction  and since
that time  neither the NYPSC or its staff has  expressed  to KeySpan any concern
about the  Transaction or its effect on rates,  regulation or competition in New
York.  Additionally,  the NYPSC does not have  statutory  jurisdiction  over the
Transaction.

95 Immediately  after the Transaction was publicly  announced,  KeySpan informed
high level officials at the MDTE about the Transaction. Neither the MDTE nor its
staff  has  expressed  to  KeySpan,  since  that  time,  any  concern  about the
Transaction or its effect on rates,  regulation or competition in Massachusetts.
Moreover,  the MDTE does not have statutory  jurisdiction  over the Transaction.

Item 5.  Procedure:

          The Commission is respectfully requested to issue and publish, as soon
as practible,  the requisite notice under Rule 23, with respect to the filing of
this Application/Declaration.

          It is  submitted  that a  recommend  decision  by a  hearing  or other
responsible officer of the Commission is not needed for approval of the proposed
Transaction. The Division of Investment Management may assist in the preparation
of  the  Commission's  decision,  unless  the  Division  opposes  the  proposals
contained herein.  There should be no waiting period between the issuance of the
Commission's order and the date on which it is to become effective.

in Item 4 of this Application/Declaration.  Consummation of the Transaction will
not result in changes in the operation of KeySpan, Eastern or their subsidiaries
that will have an impact on the environment. KeySpan is not aware of any federal
agency that has prepared or is preparing an environmental  impact statement with
respect to the transaction.

to a later  date,  time and  place,  and the  meeting  may be held as  adjourned
without further notice.  When an adjourned  meeting is reconvened,  any business
may be transacted that might have been transacted at the original meeting.

          (3) A chairman  selected by the Managers shall preside at all meetings
of the Members  unless the Members  elect from the  Membership a chairman of the
meeting.  The chairman shall  determine the order of business and the procedures
to be followed at each meeting of Members.

     2.4 Action Without a Meeting. There is no requirement that the Members hold
a  meeting  in order to take  action  on any  matter.  Any  action  required  or
permitted  to be taken by the Members  may be taken  without a meeting if one or
more  written  consents to such  action  shall be signed by Members who hold the
Membership  Interests or other  interest in the Company  required to approve the
action being taken.  Such written consents shall be delivered to the Managers at
the  principal  office of the Company and unless  otherwise  specified  shall be
effective on the date when the first consent is so delivered. The Managers shall
give prompt  notice to all  Members  who did not consent to any action  taken by
written consent of Members without a meeting.

     2.5 Voting Rights.  Unless otherwise required by the Act or this Agreement,
all actions,  approvals  and consents to be taken or given by the Members  under
the Act,  this  Agreement or otherwise  shall  require the  affirmative  vote or
written consent of Members holding a majority of the Membership Interests.

     2.6 Limitation of Liability of Members. Except as otherwise provided in the
Act,  no Member  of the  Company  shall be  obligated  personally  for any debt,
obligation or liability of the Company or of any other Member,  whether  arising
in  contract,  tort or  otherwise,  solely  by  reason  of being a Member of the
Company.  Except as  otherwise  provided in the Act, by law or expressly in this
Agreement,  no Member shall have any  fiduciary or other duty to another  Member
with respect to the business and affairs of the Company,  and no Member shall be
liable to the Company or any other Member for acting in good faith reliance upon
the provisions of this  Agreement.  Subject to Section 7.2, no Member shall have
any  responsibility  to restore any negative  balance in its Capital Account (as
defined in Section 6.1) or to contribute to or in respect of the  liabilities or
obligations of the Company or return distributions made by the Company except as
required by the Act or other applicable law; provided, however, that Members are
responsible for their failure to make required  Contributions under Section 6.2.
The failure of the Company to observe any formalities or

                                       4
<PAGE>

requirements  relating to the  exercise of its powers or the  management  of its
business  or affairs  under this  Agreement  or the Act shall not be grounds for
making its Members or Managers responsible for the liabilities of the Company.

     2.7 Authority. Unless specifically authored by the Managers, no Member that
is not a Manager  shall be an agent of the  Company or have any right,  power or
authority  to act for or to bind the  Company  or to  undertake  or  assume  any
obligation or responsibility of the Company or of any other Member.

     2.8 No Right to  Withdraw.  No  Member  shall  have any  right to resign or
withdraw from the Company without the consent of the other Members or to receive
any distribution or the repayment of its capital contribution except as provided
in Section 7.2 and Article IX upon  dissolution  and liquidation of the Company.
No Member shall have any right to have the fair value of its Membership Interest
in the Company appraised and paid out upon the resignation or withdrawal of such
Member or any other circumstances.

     2.9 Rights to Information. Members shall have the right to receive from the
Managers  upon  request  a copy of the  Certificate  and of this  Agreement,  as
amended from time to time, and such other  information  regarding the Company as
is  required  by  the  Act,  subject  to  reasonable  conditions  and  standards
established by the Managers,  as permitted by the Act, which may include without
limitation withholding or restricting the use of confidential information.

<PAGE>


the Managers  hold a meeting in order to take action on any matter.  Meetings of
the Managers may be called by any Manager. If action is to be taken at a meeting
of the  Managers,  notice of the time,  date and place of the  meeting  shall be
given to each  Manager by an  officer  or the  Manager  calling  the  meeting by
personal delivery, telephone or fax sent to the business or home address of each
Manager at least 24 hours in advance of the meeting, or by written notice mailed
to each  Manager  at either  such  address  at least 72 hours in  advance of the

its  commencement  the  inadequacy  of notice to him or her.  Managers  may also
attend a  meeting  in person or by  proxy,  and they may also  participate  in a
meeting by means of  conference  telephone or similar  communications  equipment
that permits all Managers present to hear each other. A chairman selected by the
Managers  shall  preside at all meetings of the  Managers.  The  chairman  shall
determine  the order of  business  and the  procedures  to be  followed  at each
meeting of the Managers.

     3.8  Limitation  of  Liability  of Manager.  No Manager  shall be obligated
personally  for any debt,  obligation  or  liability  of the  Company  or of any
Member,  whether  arising in contract,  tort or  otherwise,  solely by reason of
being or acting as Manager of the Company. No Manager shall be personally liable
to the Company or to its Members for breach of any  fiduciary or other duty that
does not  involve  (i) a breach of the duty of  loyalty  to the  Company  or its
Members,  (ii) acts or omissions not in good faith or which involve  intentional
misconduct or a knowing  violation of law; or (iii) a transaction from which the
Manager derived an improper personal benefit.

ARTICLE 4 - Indemnification

     4.1 Definitions. For purposes of this Article:

     "Manager"  includes (i) a person  serving as a Manager or an officer of the
Company  or in a  similar  executive  capacity  appointed  by the  Managers  and
exercising rights and duties delegated by the Managers, (ii) a person serving at
the request of the Company as a director,  Manager,  officer,  employee or other
agent of another  organization,  and (iii) any person who formerly served in any
of the foregoing capacities;

     "expenses" means all expenses, including attorneys' fees and disbursements,
actually  and  reasonably  incurred  in  defense of a  proceeding  or in seeking
indemnification  under this  Article,  and except for  proceedings  by or in the
right of the Company or alleging  that a Manager  received an improper  personal
benefit, any judgments,  awards, fines, penalties and reasonable amounts paid in
settlement of a proceeding; and

                                       7
<PAGE>

     "proceeding"  means any threatened,  pending or completed  action,  suit or
proceeding,  whether civil, criminal,  administrative or investigative,  and any
claim which could be the subject of a proceeding.

     4.2 Right to  Indemnification.  Except as limited by law and subject to the
provisions of this Article,  the Company  shall  indemnify  each of its Managers
against all expenses incurred by them in connection with any proceeding in which
a Manager is  involved as a result of serving in such  capacity,  except that no
indemnification shall be provided for a Manager regarding any matter as to which
it shall be finally  determined  that such Manager did not act in good faith and
in the  reasonable  belief  that its  action  was in the best  interests  of the
Company.  Subject to the  foregoing  limitations,  such  indemnification  may be
provided by the Company with respect to a proceeding in which it is claimed that
a Manager  received  an  improper  personal  benefit by reason of its  position,
regardless  of whether  the claim  arises out of the  Manager's  service in such
capacity,  except  for  matters  as to which it is  finally  determined  that an
improper personal benefit was received by the Manager.


     4.3 Award of  Indemnification.  The determination of whether the Company is
authorized  to indemnify a Manager  hereunder  and any award of  indemnification
shall be made in each  instance  (a) by a majority of the  Managers  who are not
parties  to the  proceeding  in  question,  (b)  by  independent  legal  counsel
appointed  by the Managers or the Members or (c) by the holders of a majority of
the Membership Interests of the Members who are not parties to the proceeding in
question.  The Company shall be obliged to pay indemnification  applied for by a
Manager  unless there is an adverse  determination  (as provided  above)  within
forty-five (45) days after the application.  If  indemnification  is denied, the
applicant may seek an independent  determination of its right to indemnification
by a court, and in such event, the Company shall have the burden of proving that
the  applicant  was   ineligible   for   indemnification   under  this  Article.
Notwithstanding the foregoing, in the case of a proceeding by or in the right of
the   Company  in  which  a  Manager  is   adjudged   liable  to  the   Company,
indemnification  hereunder  shall  be  provided  to  such  Manager  only  upon a
determination  by  a  court  having   jurisdiction  that  in  view  of  all  the
circumstances  of the case,  such Manager is fairly and  reasonably  entitled to
indemnification for such expenses as the court shall deem proper.

     4.4 Successful  Defense.  Notwithstanding  any contrary  provisions of this
Article, if a Manager has been wholly successful on the merits in the defense of
any  proceeding in which it was involved by reason of its position as Manager or
as a result of serving in such capacity (including  termination of investigative
or other proceedings without a finding of fault on the part of the Manager), the
Manager shall be indemnified by the Company against all expenses incurred by the
Manager in connection therewith.

     4.5  Advance  Payments.  Except as limited by law,  expenses  incurred by a
Manager in defending any  proceeding,  including a proceeding by or in the right
of the Company,  shall be paid by the Company to the Manager in advance of final
disposition of the proceeding  upon

                                       8
<PAGE>

receipt  of its  written  undertaking  to repay  such  amount if the  Manager is
determined  pursuant  to  this  Article  or  adjudicated  to be  ineligible  for
indemnification,  which undertaking shall be an unlimited general obligation but
need not be secured and may be accepted without regard to the financial  ability
of the  Manager  to make  repayment;  provided,  however,  that no such  advance
payment of expenses shall be made if it is determined pursuant to Section 4.3 of
this  Article  on the  basis of the  circumstances  known  at the time  (without
further investigation) that the Manager is ineligible for indemnification.

     4.6  Insurance.  The  Company  shall have power to  purchase  and  maintain
insurance  on behalf of any  Manager,  officer,  agent or  employee  against any
liability or cost incurred by such person in any such capacity or arising out of
its status as such,  whether or not the  Company  would have power to  indemnify
against such liability or cost.

     4.7 Heirs and Personal  Representatives.  The  indemnification  provided by
this   Article   shall  inure  to  the   benefit  of  the  heirs  and   personal
representatives of each Manager.

     4.8 Non-Exclusivity.  The provisions of this Article shall not be construed
to limit the power of the Company to indemnify its Managers,  Members, officers,
employees  or  agents  to the full  extent  permitted  by law or to  enter  into
specific agreements,  commitments or arrangements for indemnification  permitted
by law. The absence of any express  provision for  indemnification  herein shall
not limit any right of indemnification existing independently of this Article.

     4.9 Amendment. The provisions of this Article may be amended or repealed in
accordance with Section 10.4; however, no amendment or repeal of such provisions
that  adversely  affects the rights of a Manager under this Article with respect
to its acts or  omissions  at any time prior to such  amendment  or repeal shall
apply to such Manager without its consent.

                        [ARTICLE I - Conflicts of Interest


     4.10  Transactions  with  Interested  Persons.  Unless  entered into in bad
faith,  no  contract or  transaction  between the Company and one or more of its
Managers  or  Members,  or  between  the  Company  and  any  other  corporation,
partnership,  association  or other  organization  in  which  one or more of its
Managers  or Members  have a  financial  interest  or are  directors,  partners,
Managers or officers, shall be voidable solely for this reason or solely because
such Manager or Member was present or participated in the  authorization of such
contract or transaction if:

          (1) the  material  facts as to the  relationship  or  interest of such
Manager or Member and as to the contract or transaction  were disclosed or known
to the other Managers

                                       9
<PAGE>

(if any) or Members  and the  contract  or  transaction  was  authorized  by the
disinterested Managers (if any) or Members; or

          (2) the contract or transaction was fair to the Company as of the time
it was authorized,  approved or ratified by the disinterested  Managers (if any)
or Members; and no Manager or Member interested in such contract or transaction,
because of such interest,  shall be considered to be in breach of this Agreement
or liable  to the  Company,  any  Manager  or  Member,  or any  other  person or
organization  for any loss or expense  incurred  by reason of such  contract  or
transaction be accountable for any gain or profit realized from such contract or
transaction.]

ARTICLE 5 - Capital Accounts and Contributions

     5.1 Capital Accounts.

          (1) There shall be  established on the books of the Company a separate
capital account (a "Capital Account") for each Member.

          (2) The  Capital  Account of each  Member  (regardless  of the time or
manner in which such  Member's  interest was  acquired)  shall be  maintained in
accordance  with the rules of Section  704(b) of the  Internal  Revenue  Code of
1986,  as  amended,  from time to time (the  "Code"),  and  Treasury  Regulation
Section 1.704-l(b)(2)(iv). Adjustments shall be made to the Capital Accounts for
distributions  and allocations as required by the rules of Section 704(b) of the
Code and the Treasury Regulations thereunder.

          (3) If  there is a  transfer  of all or a part of an  interest  in the
Company by a Member,  the Capital Account of the transferor that is attributable
to the transferred interest shall carry over to the transferee of such Member.

          (4)  Subject  to  Section  7.2,  notwithstanding  any other  provision
contained  herein to the  contrary,  no Member  shall be required to restore any
negative balance in its Capital Account.

     5.2 Contributions.  Each Member shall make the contributions to the capital
of  the  Company   (herein   "Contributions")   specified  on  Schedule  A.  All
Contributions  shall be paid in cash unless otherwise specified on Schedule A or
agreed  to by the  Members.  Except  as set  forth on  Schedule  A, no Member or
Manager shall be entitled or required to make any contribution to the capital of
the  Company;  however,  the Company may borrow from its Members as well as from
banks or other  lending  institutions  to  finance  its  working  capital or the
acquisition of assets upon such terms and conditions as shall be approved by the
Managers,   and  any  such  borrowing  from  Members  shall  not  be  considered
Contributions or reflected in their Capital Accounts.  The value of all non-cash
Contributions  made by Members shall be set

                                       10
<PAGE>

forth on Schedule A. No Member shall be entitled to any interest or compensation
with  respect to its  Contribution  or any  services  rendered  on behalf of the
Company  except as  specifically  provided in this  Agreement or approved by the
Managers.  No  Member  shall  have  any  liability  for  the  repayment  of  the
Contribution  of any other  Member and each Member shall look only to the assets
of the Company for return of its Contribution.

ARTICLE 6 - Profits Losses and Distributions

     6.1 Profits. Losses and Distributions

          (1) All profits and losses  arising from the normal course of business
operations or otherwise and all cash  available for  distribution  from whatever
source,  commencing  with the date of this  Agreement,  shall  be  allocated  or
distributed to the Members according to their Membership Interests.

          (2) All profits and losses  allocated to the Members shall be credited
or charged,  as the case may be, to their Capital Accounts.  The terms "profits"
and "losses" as used in this  Agreement  shall mean income and losses,  and each
item of income,  gain,  loss,  deduction or credit entering into the computation
thereof, as determined in accordance with the accounting methods followed by the
Company and computed in a manner  consistent  with Treasury  Regulation  Section
1.704-l(b)(2)(iv).  Profits and losses for Federal  income tax purposes shall be
allocated  in the same manner as profits and losses for purposes of this Article
VII, except as provided in Section 7.3(a).

          6.2  Distributions Upon Dissolution.

          (1) Upon  dissolution and  termination,  after payment of, or adequate
provision for, the debts and obligations of the Company, the remaining assets of
the Company (or the proceeds of sales or other  dispositions  in  liquidation of
the  Company  assets,  as  may  be  determined  by the  remaining  or  surviving
Member(s))  shall be distributed to the Members in accordance  with the positive
balances in their Capital Accounts after taking into account all Capital Account
adjustments  for the  Company  taxable  year.  In the event  that a Member has a
negative balance in his Capital Account following the liquidation of the Company
or his interest in the Company  after  taking into  account all Capital  Account
adjustments for the Company taxable year in which the liquidation  occurs,  such
Member shall pay to the Company in cash an amount  equal to the deficit  balance
in the Capital Account of such Member.

          (2) With  respect  to assets  distributed  in kind to the  Members  in
liquidation  or  otherwise,   (i)  any  unrealized  appreciation  or  unrealized
depreciation  in the values of such  assets  shall be deemed to be  profits  and
losses  realized by the Company  immediately  prior to the  liquidation or other
distribution  event;  and (ii) such profits and losses shall be allocated to the
Members and credited or charged to their Capital  Accounts,  and any property so

                                       11
<PAGE>

distributed shall be treated as a distribution of an amount in cash equal to the
excess of such fair market value over the outstanding  principal  balance of and
accrued  interest  on any debt by which  the  property  is  encumbered.  For the
purposes  of this  Section  7.2(b),  "unrealized  appreciation"  or  "unrealized
depreciation"  shall mean the  difference  between the fair market value of such
assets,  taking into account the fair market value of the  associated  financing
but subject to Section  770l (g) of the Code,  and the  Company's  basis in such
assets as determined under Treasury Regulation Section 1.704-l(b).  This Section
7.2(b) is merely intended to provide a rule for allocating  unrealized gains and
losses upon liquidation or other  distribution  event, and nothing  contained in
this Section 7.2(b) or elsewhere in this Agreement is intended to treat or cause
such  distributions  to be treated as sales for value.  The fair market value of
such assets  shall be  determined  by an appraiser to be selected by the Manager
with the Consent of the Members.

     6.3 Special Provisions.

     Notwithstanding the foregoing provisions in this Article VII:

          (1) Income,  gain, loss and deduction with respect to Company property
which has a variation  between its basis  computed in  accordance  with Treasury
Regulation  Section  1.704-(b)  and its basis  computed  for Federal  income tax
purposes shall be shared among Members so as to take account of the variation in
a manner  consistent  with the  principles  of  Section  704(c)  of the Code and
Treasury Regulation Section 1.704-3.

          (2)  Section  704 of the  Code  and the  Treasury  Regulations  issued
thereunder,  including  but not limited to the  provisions  of such  regulations
addressing  qualified  income  offset  provisions,   minimum  gain  charge  back
requirements and allocations of deductions  attributable to nonrecourse debt and
partner  nonrecourse  debt,  are  hereby  incorporated  by  reference  into this
Agreement.

     6.4  Distribution  of Assets in Kind.  No  Member  shall  have the right to
require any  distribution  of any assets of the Company to be made in cash or in
kind.  If the Managers  determine to  distribute  assets of the Company in kind,
such assets  shall be  distributed  on the basis of their fair  market  value as
determined by the Managers.  Any Member  entitled to any interest in such assets
shall, unless otherwise  determined by the Managers,  receive separate assets of
the  Company,  and not an interest  as  tenant-in-common  with other  Members so
entitled in each asset being distributed. Distributions in kind need not be made
on a pro-rata basis but may be made on any basis which the Managers determine to
be reasonable under the circumstances.

ARTICLE 7 - Transfers of Interests

     7.1  Transfer of a Member's Membership Interest.

                                       12
<PAGE>

     (1) Except as set forth in the first sentence of Section 8.2, no Member may
sell,  assign,  give,  pledge,  hypothecate,  encumber  or  otherwise  transfer,
including, without limitation, any assignment or transfer by operation of law or
by order of court, such Member's  Membership Interest in the Company or any part
thereof,  or in all or any part of the  assets of the  Company,  without a prior
written  consent of a majority of the Managers and in accordance  with the terms
of Section 8. l(b).  The  granting  or denying of such  consent  shall be in the
Managers' absolute discretion. Any attempted sale, transfer,  assignment, pledge
or other disposition in contravention of the provisions of this section shall be
void and ineffectual and shall not bind, or be recognized, by the Company.

     (2) After  obtaining a prior written consent of a majority of the Managers,
but before any  Membership  Interest or any part thereof may be sold,  assigned,
gifted, pledged,  hypothecated,  encumbered or otherwise transferred,  including
transfer  by  operation  of law or by order of court,  the Member  holding  such
Membership  Interest  proposing such sale or transfer (the  "Transferor")  shall
first give  written  notice  thereof to other  Members at least  sixty (60) days
prior to the  proposed  date of  transfer  (the  "Transfer  Date")  stating  the
proposed  transferee,  the Membership  Interest proposed to be transferred,  the
purchase price, if any, and the terms of the proposed  transaction.  The Members
receiving  such notice  (the  "Purchasing  Members")  shall  thereupon  have the
option,  but not the  obligation,  to acquire all, but not less than all, of the
Membership Interest proposed to be sold or transferred by the Transferor for the
Purchase Price  determined  pursuant to Section 8.1 (d) (the "Purchase  Price").
Within thirty (30) days after the giving of such notice by the Transferor,  each
Purchasing  Member  shall  give  written  notice  ("Purchase   Notice")  to  the
Transferor  stating  whether or not he or she elects to  exercise  the option to
purchase and a date and time (the "Closing  Date") for the  consummation  of the
purchase not less than sixty (60) or more than ninety (90) days after the giving
of the Purchase Notice. If two (2) or more Purchasing Members desire to purchase
the Membership Interest proposed to be sold or transferred, then, in the absence
of an  agreement  between  or among  them,  each such  Purchasing  Member  shall
purchase  the  Membership  Interest  proposed to be sold or  transferred  in the
proportion  that his or her Membership  Interest  bears to the total  Membership
Interests of all the Purchasing Members who desire to so purchase.  Failure by a
Purchasing  Member to deliver a Purchase  Notice within the time period  allowed
shall be deemed an  election  by such  Purchasing  Member not to  exercise  such
option. If the Purchase Price is determined by appraisal as set forth in Section
8.1(d)(ii),  a Purchasing  Member may rescind his or her election to purchase by
written notice to the Transferor given within ten (10) days after being notified
of the determination of the appraisers.

     (3) If the Purchasing  Members waive in writing their option to purchase or
fail to exercise  their right to purchase  within the time period  allowed,  the
Transferor may transfer such  Membership  Interest at any time during the 60-day
period after the termination of such time period, but only upon the terms and to
the transferee stated in its notice delivered


                                       13
<PAGE>

pursuant to subsection (b). After such Membership Interest is so transferred, or
if the transfer is not  consummated  within such period the Membership  Interest
shall again become subject to the terms of this Agreement.

          (4) The Purchase Price shall be determined as follows:

              (1)    In the case of a proposed sale or transfer under  paragraph
                     (b) to a third  party in a bona fide  transaction  for fair
                     value  payable in cash or the  equivalent  currently  or in
                     future installments, the Purchase Price for such Membership
                     Interests  shall be the value  offered by such third  party
                     payable upon the same terms.

              (2)    In all other cases, including without limitation a proposed
                     transfer  or  other  disposition  not  constituting  a sale
                     described in  subsection  (i), the Purchase  Price shall be
                     the fair  market  value of the  Membership  Interest  being
                     purchased as of the last day of the month immediately prior
                     to the month  during which the  transferor  gave his or her
                     notice.  "Fair market  value" as of any date shall mean the
                     cash price  obtainable in an  arm's-length  sale between an
                     informed  and  willing   buyer  (under  no   compulsion  to
                     purchase)  and an  informed  and willing  seller  (under no
                     compulsion to sell) of the Membership Interest,  based upon
                     the going concern value of the Company, taking into account
                     any minority or  non-control  discount.  If the parties are
                     unable  to agree  upon the fair  market  value,  such  fair
                     market value shall be  determined  by appraisal as follows:
                     Either party may require appraisal by giving written notice
                     to the other party and appointing an independent appraiser.
                     The other party shall deliver a written  notice  appointing
                     an  independent  appraiser  within  fifteen (15) days after
                     receipt of the notice from the other. The two appraisers so
                     appointed,  or if only one  appraiser  is  appointed,  that
                     appraiser, shall promptly seek to determine the fair market
                     value.  If the two  appraisers  cannot agree within  thirty
                     (30)  days  of  their  appointment,   a  third  independent
                     appraiser  shall be chosen within ten (10) days  thereafter
                     by the mutual  consent of such first two  appraisers or, if
                     such   first  two   appraisers   fail  to  agree  upon  the
                     appointment of a third appraiser, such appointment shall be
                     made  by the  Boston  office  of the  American  Arbitration
                     Association,  or any organization  successor  thereto,  and
                     shall be a disinterested  person qualified in the valuation
                     of  business  enterprises  engaged  in the same or  similar
                     lines of  business  as the  Company.  The three  appraisers
                     shall

                                       14
<PAGE>

                     make the  determination in accordance with the rules of the
                     American Arbitration Association or any such successor then
                     in effect,  and such  determination  shall be  binding  and
                     conclusive  on the parties.  Each party shall pay the costs
                     of its own  appraiser and shall share equally in the costs,
                     if  any,  of a  third  appraiser  and any  other  costs  of
                     arbitration, excluding their own costs.

     7.2 Death or  Incompetence  of a Member.  If a Member dies,  such  Member's
executor,   administrator,   or  trustee,  or,  if  he  or  she  is  adjudicated
incompetent, such Member's guardian, or, if it is a corporation,  trust, limited
liability  company  or  partnership  and is  dissolved,  the  liquidator,  shall
automatically  become an assignee (the "Assignee") of the Membership Interest of
the  deceased,  incompetent,  or  dissolved  Member.  The  Assignee  may receive
distributions  and shall  have all the  rights of a Member  for the  purpose  of
settling or managing such deceased or incompetent Member's estate, but shall not
be a Member  and  shall  not have the  power to vote  such  Member's  Membership
Interest.  The Assignee shall also have such power as the decedent,  incompetent
or  dissolved  entity  possessed  to: (1) assign all or any part of the Member's
Membership  Interest  subject to  Section  8.1;  and (2) to  satisfy  conditions
precedent to the assignment of the Membership Interest set forth in Section 8.1.

     7.3 Admission of Member; Effect of Transfer.


          (1) In no event may any person obtaining a Membership  Interest in the
Company by assignment,  transfer,  pledge or other means from an existing Member
be admitted  as a  successor  Member  without  the  affirmative  vote or written
consent of Members of the  Membership  Interests  exclusive  in each case of the
Member whose Membership Interest is being transferred.

          (2) If the  transferee is admitted as a Member or is already a Member,
the Member  transferring its Membership  Interest shall be relieved of liability
with respect to the transferred  Membership  Interest  arising or accruing under
this  Agreement  on or after the  effective  date of the  transfer,  unless  the
transferor  affirmatively  assumes such liability;  provided,  however, that the
transferor  shall not be relieved of any liability for prior  distributions  and
unpaid   contributions   unless  the  transferee   affirmatively   assumes  such
liabilities.

          (3) Any person who acquires in any manner a Membership Interest or any
part thereof in the Company, whether or not such person has accepted and assumed
in writing the terms and  provisions  of this  Agreement  or been  admitted as a
Member,  shall be deemed by the acquisition of such Membership  Interest to have
agreed to be subject  to and bound by all of the  provisions  of this  Agreement
with respect to such Membership  Interest,  including  without  limitation,  the
provisions  hereof with respect to any  subsequent  transfer of such  Membership
Interest.

distribution,  the liquidating trustees may continue to operate the business and

     9.2  Notices.  Except  as  expressly  set  forth  to the  contrary  in this
Agreement, all notices,  requests, or consents required or permitted to be given
under  this  Agreement  must be in  writing  and  shall be  deemed  to have been
properly  given if sent by registered or certified  mail,  postage  prepaid,  by
commercial overnight courier, by facsimile or if delivered in hand to Members at
their  addresses on Schedule A, or such other address as a Member may specify by
notice to the  Managers and to the Company or the Managers at the address of the
principal  office of the Company  specified in Section l .3. Whenever any notice
is required to be given by law, the  Certificate  or this  Agreement,  a written
waiver thereof, signed by the person entitled to notice, whether before or after
the time  stated  therein,  shall be  deemed  equivalent  to the  giving of such
notice.

agreement of the Members and the Managers relating to the Company and supersedes
all prior oral or  written  agreements  or  understandings  with  respect to the
Company.  This  Agreement is binding on and inures to the benefit of the parties
and their respective successors, permitted assigns and legal representatives.

Agreement  may be  amended  or  modified  from  time to time  only by a  written

construed  in  accordance  with the law of The  Commonwealth  of  Massachusetts,
exclusive of its conflict-of-laws principles. In the event of a conflict between
the  provisions of this  Agreement and any provision of the  Certificate  or the
Act, the  applicable  provision of this Agreement  shall control,  to the extent
permitted by law. If any provision of this Agreement or the application  thereof
to any person or  circumstance is held invalid or  unenforceable  to any extent,
the remainder of this Agreement and the  application of that provision  shall be
enforced to the fullest extent permitted by law.

     9.6  Further  Assurances.   In  connection  with  this  Agreement  and  the
transactions  contemplated  hereby,  each Member  shall  execute and deliver any
additional documents and instruments and perform any additional acts that may be
necessary  or  appropriate  to  effectuate  and perform the  provisions  of this
Agreement and those transactions, as requested by the Managers.

     9.7 Waiver of Certain Rights.  Each Member  irrevocably waives any right it
may have to maintain any action for  dissolution of the Company or for partition
of the property of the Company.  The failure of any Member to insist upon strict
performance of a covenant hereunder or of any obligation hereunder, irrespective
of the length of time for which such failure continues, shall not be a waiver of
such  Member's  right to demand  strict  compliance  herewith in the future.  No
consent or waiver,  express  or  implied,  to or of any breach

                                       17
<PAGE>

or default in the  performance of any obligation  hereunder  shall  constitute a
consent or waiver to or of any other breach or default in the performance of the
same or any other obligation hereunder.

capacities as such. Notwithstanding any contrary provision of this Agreement, no
such  creditor or person shall obtain any rights under this  Agreement or shall,
by reason of this Agreement,  be permitted to make any claim against the Company
or any Member or Manager.

describe the scope of this Agreement or the intent of any provision hereof.

     9.10  Counterparts.  This  Agreement  may  be  executed  in any  number  of
counterparts  with  the  same  effect  as if all  parties  had  signed  the same
document,  and all counterparts shall be construed together and shall constitute
the same instrument.

                    NEW HAMPSHIRE PUBLIC UTILITIES COMMISSION

                                  DG 99-______

                        Re: EnergyNorth Natural Gas, Inc.

   Petition for Approval of the Acquisition of EnergyNorth Natural Gas, Inc.,
                 by Eastern Enterprises and KeySpan Corporation
                 ----------------------------------------------


         Eastern  Enterprises  ("Eastern"),   KeySpan  Corporation  ("KeySpan"),
EnergyNorth,  Inc.  ("EnergyNorth")  and EnergyNorth  Natural Gas, Inc. ("ENGI")
(together,  the "Joint  Petitioners")  hereby file this petition requesting that
the New Hampshire Public Utilities  Commission (the  "Commission"),  pursuant to
the provisions of RSA 369:8,II and RSA 374:33,  approve:  (1) the acquisition by
Eastern of EnergyNorth,  the parent company of ENGI,  which will be accomplished
through the merger of EnergyNorth and EE Acquisition  Company  ("Merger Sub"), a
wholly  owned  subsidiary  of  Eastern;  and (2)  the  indirect  acquisition  of
EnergyNorth  by KeySpan,  which will be  accomplished  through the  simultaneous
merger of Eastern and ACJ Acquisition LLC ("ACJ"), a subsidiary of KeySpan.

         As described  below, and as supported in detail by the prefiled written
testimony  submitted  on  behalf  of the  Joint  Petitioners,  the  transactions
described  above  will  result in "no net harm" to the  customers  of ENGI,  and
therefore,  the proposed transactions meet the public-interest standard embodied
in RSA 369:8,II and RSA 374:33. In support thereof,  the Joint Petitioners state
the following:

1.   EnergyNorth  is a New  Hampshire  corporation  with a  principal  place  of
     business in  Manchester,  New  Hampshire.  EnergyNorth  is the owner of 100
     percent  of the

<PAGE>
                                      -2-

     common stock of ENGI, EnergyNorth Propane, Inc., ENI Mechanicals,  Inc. and
     EnergyNorth Realty, Inc.

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.  Eastern is a holding  company
     that owns 100 percent of the common stock of Boston Gas  Company,  Colonial
     Gas Company and Essex Gas Company,  which are local distribution  companies
     serving a total of 735,000 natural gas customers in Massachusetts.  Eastern
     also owns and operates several unregulated business enterprises.

3.   KeySpan is a New York  corporation  with a  principal  place of business in
     Brooklyn,  New York.  KeySpan is a holding company that owns 100 percent of
     the common stock of two local distribution companies serving a total of 1.6
     million  natural gas customers in New York,  New York and Long Island,  New
     York, under the name of The Brooklyn Union Gas Company and KeySpan Gas East
     Corporation d/b/a Brooklyn Union Company of Long Island (collectively,  the
     "Brooklyn Union Companies"). KeySpan also owns and operates other regulated
     electric generation  companies in the state of New York, as well as several
     unregulated business enterprises.

4.   ENGI is a New Hampshire  corporation and a public utility as defined in RSA
     362:2,  with a principal  place of business in  Manchester,  New Hampshire.
     ENGI  is  the  largest  natural  gas  utility  in  New  Hampshire   serving
     approximately  72,000  customers in 28 cities and towns in the southern and
     central part of New  Hampshire  and the City of Berlin in the northern part
     of the state.

                                      -3-

5.   On July 14, 1999,  Eastern and  EnergyNorth  entered into an Agreement  and
     Plan of Reorganization  (the "EnergyNorth  Merger Agreement") that provides
     for the  creation of Merger Sub and the  subsequent  merger of  EnergyNorth
     with and into Merger Sub, subject to the necessary  approvals of government
     regulatory  authorities having  jurisdiction.  On November 4, 1999, KeySpan
     and Eastern  entered  into an  Agreement  and Plan of Merger (the  "Eastern
     Merger Agreement") that provides for the creation of ACJ as a subsidiary of
     KeySpan and the subsequent merger of ACJ with and into Eastern,  subject to
     the  necessary  approvals  of  government  regulatory   authorities  having
     jurisdiction.

6.   On November  4, 1999,  in  conjunction  with the  execution  of the Eastern
     Merger Agreement,  Eastern and EnergyNorth  amended the EnergyNorth  Merger
     Agreement (the "EnergyNorth Amendment") to provide for the merger of Merger
     Sub  with and into  EnergyNorth,  subject  to the  necessary  approvals  of
     government   regulatory   authorities   having   jurisdiction  and  of  the
     shareholders of the respective  companies.  If such approvals are obtained,
     these  agreements  would result in  EnergyNorth  becoming a direct,  wholly
     owned subsidiary of Eastern and, simultaneously,  an indirect subsidiary of
     KeySpan.  A copy of the  EnergyNorth  Merger  Agreement and the EnergyNorth
     Amendment  (together,   the  "Amended  EnergyNorth  Merger  Agreement")  is
     appended to the  prefiled  testimony of Walter J.  Flaherty as  Attachments
     WJF-1 and WJF-2,  respectively.  A copy of the Eastern Merger  Agreement is
     appended  thereto as Attachment  WJF-3.
<PAGE>
                                      -4-

7.   The Amended  EnergyNorth  Merger Agreement sets forth the following actions
     that, in  conjunction  with the Eastern  Merger  Agreement,  will result in
     EnergyNorth becoming an indirect subsidiary of KeySpan:

     (a)  EnergyNorth's  stockholders will vote on the approval of the merger of
          EnergyNorth  with  Merger  Sub.

     (b)  Upon receipt of the necessary  regulatory  approvals and the filing of
          the  Articles  of  Merger,  Merger  Sub will be  merged  with and into
          EnergyNorth in accordance  with the laws of the State of New Hampshire
          (the  "Reverse  Merger").  This type of merger is known as a  "reverse
          triangular  merger" for tax and reorganization  purposes.  EnergyNorth
          will be the  surviving  corporation  and will  continue  to operate as
          "EnergyNorth, Inc." under the laws of the State of New Hampshire.

     (c)  As set  forth  in  the  Amended  EnergyNorth  Merger  Agreement,  each
          outstanding share of EnergyNorth common stock will be extinguished and
          automatically converted into the right to receive $61.13 in cash. This
          conversion will be a taxable event to the shareholders of EnergyNorth.

     (d)  Upon the completion of the Reverse Merger,  EnergyNorth  will become a
          wholly owned  subsidiary of Eastern.  As set forth above,  pursuant to
          the Eastern  Merger  Agreement,  ACJ will thereupon be merged with and
          into Eastern. As a result,  Eastern,  and indirectly,  EnergyNorth and
          ENGI, will become subsidiaries of KeySpan.

8.   In the event that the Eastern Merger  Agreement with KeySpan  terminates or
     expires,  then the merger of  EnergyNorth  with and into Merger Sub will be
     accomplished in

<PAGE>

     accordance  with  the  Amended  EnergyNorth  Merger  Agreement,  under  the
     following terms:

     (a)  EnergyNorth will be merged with and into Merger Sub with Merger Sub as
          the surviving corporation operating as "EnergyNorth,  Inc.," under the
          laws of the State of New Hampshire (the "Forward  Merger").  This type
          of  merger  is  known as a  "forward  triangular  merger"  for tax and
          reorganization purposes.

     (b)  Each   outstanding   share  of   EnergyNorth   common  stock  will  be
          extinguished and automatically  converted into the right to receive at
          the effective time of the Forward Merger one of the following: (i) the
          per-share  cash  amount of $47.00;  (ii) a number of shares of Eastern
          common  stock,  $1.00  par  value,   pursuant  to  an  exchange  ratio
          determined at the time of the transaction in accordance with the terms
          of the Amended EnergyNorth Merger Agreement; or (iii) a combination of
          cash and shares of Eastern.

     (c)  The holders of EnergyNorth  common stock are permitted to indicate the
          preferred  form of payment for their shares  subject to the limitation
          that 50.1 percent of  EnergyNorth  shares will be exchanged for shares
          of Eastern  common stock with the remaining  EnergyNorth  shares to be
          exchanged for cash. In order to ensure that the merger  qualifies as a
          tax-free reorganization, shareholder elections would be subject to the
          further limitation that, in no event, would the total value of Eastern
          shares  so   exchanged   fall  below  45  percent  of  the   aggregate
          consideration used to complete the transaction.

     (d)  The completion of the Forward Merger will cause  EnergyNorth,  and its
          subsidiary ENGI, to become wholly owned subsidiaries of Eastern.

10.  Consummation of the merger between EnergyNorth and Merger Sub is subject to
     certain conditions, which include regulatory approval by the Commission, as
     set  forth  in  Article  6 of the  Amended  EnergyNorth  Merger  Agreement.
     Accordingly,  Article 6.1(b)  specifies  that, with regard to rates and the
     recovery of costs  associated  with the merger  (including the  acquisition
     premium and transaction and integration  costs), the Commission's  approval
     is required  upon terms and  conditions  that are not less  favorable  than
     those set forth by the Commission in Re: Northern  Utilities,  Inc., Docket
     No. DF  98-040,  Order No. 22,983  (1998) ("Northern Utilities").

11.  In Northern  Utilities,  the Commission  approved a stipulation between the
     parties that granted the right to request recovery of merger-related  costs
     in a future  proceeding on the condition that the benefits of the merger to
     customers  are  demonstrated  to  equal  or  exceed  such  costs.  Northern
     Utilities at 4, 7. In approving the stipulation,  the Commission ruled that
     customers  would not be harmed as a result  of the  merger  because,  among
     other things,  the conditions set forth therein:  (1) required  Northern to
     substantiate  savings  resulting  from the merger before seeking to include
     any  part  of  the  acquisition  premium  in  rates;  and  (2)  deferred  a
     determination regarding capital structure issues until the time of any such
     request. Id. at 7.

12.  In New England  Electric System,  DE 99-035,  Order No. 23,308 (1999) ("New
     England  Electric"),  the Commission  stated that the mandate in RSA 369:8,
     which  requires that mergers will "not adversely  affect the rates,  terms,
     service,  or operation of the public utility within the state" embodies the
     same standard  reflected in RSA 374:33,  which authorizes the Commission to
     approve mergers that are "lawful,  proper and in the public  interest." New
     England Electric, slip op. at 16. Thus, proposed

<PAGE>
                                      -7-

     mergers  must  meet a "no net  harm"  test in order to be  approved  by the
     Commission.  Id. The Commission stated that, in -- applying the no net harm
     test,  it must "assess the  benefits  and risks of the proposed  merger and
     determine  what the overall  effect on the public  interest will be, giving
     the  transaction  . . . approval if the effect is at worst neutral from the
     public interest  perspective." Id. Accordingly,  the Commission's  standard
     will be met where an  applicant  for  approval of a -- merger  demonstrates
     that  customers  would be no worse off with the  merger  than  without  the
     merger. Id. at 17.

13.  Pursuant to the Commission's findings in Northern Utilities and New England
     Electric,  the Joint Petitioners file herewith a merger proposal that meets
     and exceeds the Commission's no net harm standard.  Specifically, the Joint
     Petitioners  propose:  (1) to provide  customers  with  immediate  gas-cost
     savings through a 2.2 percent burner-tip price reduction;  (2) to work with
     the Commission to develop a mechanism for identifying and quantifying other
     cost savings that are achievable only as a direct result of the merger; and
     (3) to have the opportunity to request,  in a future  proceeding before the
     Commission, the recovery of merger-related costs required to accomplish the
     transaction if such costs are  demonstrated to be offset by  merger-related
     savings.

14.  The proposed transactions and the expected benefits are discussed in detail
     in the  accompanying  testimony  of  Walter  J.  Flaherty,  Executive  Vice
     President and Chief  Financial  Officer of Eastern,  Michelle L.  Chicoine,
     Executive Vice President of EnergyNorth  and President and Chief  Operating
     Officer of ENGI,  Joseph F. Bodanza,  Senior Vice President,  Treasurer and
     Chief Financial  Officer of Boston Gas, William R. Luthern,  Vice President
     of Gas Resources for Boston Gas and Craig G. Matthews,  President and Chief
     Operating Officer of KeySpan.

                                      -8-

15.  As discussed in the testimony of William R. Luthern,  ENGI's customers will
     benefit substantially from increased supply options and enhanced purchasing
     power as a result of the mergers  described  above. The ability to dispatch
     across Eastern's combined  distribution  system will increase  flexibility,
     enable the  optimization of existing  gas-supply  resources,  encourage and
     facilitate more efficient  purchasing  capability and secure the ability to
     exercise  broader system control.  The expanded supply  portfolio will also
     increase  the overall  reliability  of ENGI's  distribution  system.  These
     benefits will result in an immediate 2.2 percent  burner-tip rate reduction
     for customers of ENGI.  As described  below,  the potential for  additional
     cost  reductions  resulting  from  KeySpan's   acquisition  of  Eastern  is
     addressed in the testimony of Craig G. Matthews.

16.  As  discussed  in the  testimony  of  Michelle  L.  Chicoine  and Joseph F.
     Bodanza,  the merger will result in the  creation of economies of scale and
     the elimination of redundant  resources,  thereby producing  operations and
     maintenance  expense cost savings that could not be achieved in the absence
     of the merger. In addition, as a result of the merger, Eastern will be able
     to extend  certain  resources  of Boston  Gas  Company  to ENGI,  including
     information-systems technology and customer-service enhancements,  allowing
     ENGI to avoid  substantial  investment in similar  systems,  which would be
     required  in the  absence of the  merger.  Moreover,  Eastern's  ability to
     achieve  these and other cost  reductions  is enhanced  because the service
     territory of ENGI is contiguous with the service  territory of Colonial Gas
     Company (a gas distribution subsidiary of Eastern).

                                      -9-

17.  As discussed in the testimony of Walter J. Flaherty, approval of the merger
     in accordance  with the terms of Northern  Utilities will provide ENGI with
     the opportunity to request, in the future, recovery of merger-related costs
     upon a finding  by the  Commission  that  identified  and  quantified  cost
     savings  resulting  from the merger  warrant  such  recovery.  Because  the
     recovery of merger-related costs through merger-related savings would leave
     ENGI's customers no worse off with the merger than without, the merger will
     result in "no net harm" to ENGI's  customers.  In fact, as described in the
     supporting  testimony  filed with this  petition,  the merger will  provide
     numerous benefits to ENGI's customers,  including an immediate reduction in
     burner-tip  prices and future  efficiencies  that will result in  long-term
     cost savings and  service-quality  improvements  for  customers.  Thus, the
     overall effect of the proposed merger will directly benefit customers.

18.  As described in the testimony of Craig G. Matthews,  Eastern's  merger with
     KeySpan will cause EnergyNorth to become an indirect subsidiary of KeySpan.
     KeySpan's acquisition of Eastern, however, will not diminish any commitment
     advanced  by Eastern  with regard to the effect of the merger on the rates,
     terms,  service and operations of ENGI.  KeySpan is similarly  committed to
     continued  investment in ENGI's distribution  system,  continued support of
     community  interests and to  maintaining a local  presence to provide safe,
     reliable and cost-effective service to ENGI customers.  Moreover, Eastern's
     merger with KeySpan may present the opportunity to achieve incremental cost
     savings and  enhancements to reliability and customer  service beyond those
     identified and provided by Eastern.  Because  KeySpan's merger with Eastern
     will have no effect on the rates,  terms,  service and

<PAGE>

                                      -10-

     operations of ENGI,  KeySpan's  indirect  acquisition of  EnergyNorth  will
     result in no net harm to ENGI's customers.


19.  As further  described in the testimonies of Messrs.  Matthews and Flaherty,
     the  Joint  Petitioners  seek  approval  of the  acquisition  of ENGI  both
     directly and indirectly by Eastern and KeySpan, respectively.  However, the
     KeySpan-Eastern  merger  is not  contingent  upon  the  Eastern-EnergyNorth
     transaction,  and therefore,  the Commission's  decision in this proceeding
     would affect only EnergyNorth's  participation in the transaction and would
     not affect KeySpan's acquisition of Eastern.

WHEREFORE, the Joint Petitioners respectfully request that the Commission:

     a.   Determine  that the proposed  acquisition  of  EnergyNorth by Eastern,
          which  will be  accomplished  through  the merger of  EnergyNorth  and
          Merger Sub, and that the terms thereof will result in "no net harm" to
          ENGI's  customers;

     b.   Determine  that the proposed  acquisition  of  EnergyNorth  by KeySpan
          through its acquisition of Eastern, which will be accomplished through
          the merger of Eastern and ACJ, and that the terms  thereof will result
          in "no net harm" to ENGI's customers;

     c.   Approve the  above-described  transactions as filed in accordance with
          RSA 369:8,II(b)(2),  or, alternatively,  RSA 374:33;

     d.   Determine  that  the  ENGI  may,  in a future  proceeding  before  the
          Commission, request the recovery of merger-related costs if it is able
          to substantiate that merger-related savings meet or exceed such costs,
          consistent with the Commission's findings in Northern Utilities; and
<PAGE>
                                      -11-

     e.   Issue such other and further  orders as may be necessary  and just and
          reasonable.



                                       Respectfully  submitted,

                           PUBLIC UTILITIES COMMISSION

                         Testimony of Walter J. Flaherty

I.       INTRODUCTION

Q.       Please state your name and business address.

A.       My name is Walter J. Flaherty. My business address is 9 Riverside Road,
         Weston, Massachusetts 02493.

Q.       By whom are you employed,  and in what capacity?

A.       I am Executive  Vice President and Chief  Financial  Officer of Eastern
         Enterprises  ("Eastern").  I am also a Director  of Boston Gas  Company

Q.       What is the purpose of your testimony?

A.       The  purpose of my  testimony  is to  describe  various  aspects of the
         proposed  acquisition by Eastern of EnergyNorth,  Inc.  ("EnergyNorth")
         and its principal  operating  subsidiary  EnergyNorth Natural Gas, Inc.
         ("ENGI")   and  of   Eastern  by   KeySpan   Corporation   ("KeySpan").
         Specifically,  my testimony provides:  (i) a background  description of
         Eastern;  (ii) Eastern's  rationale for the  acquisition of EnergyNorth
         and for the merger with  KeySpan and the  benefits  that will accrue to
         customers; (iii) a description of the transaction with EnergyNorth,  as
         set forth in the Agreement and Plan of Reorganization (the "EnergyNorth
         Merger Agreement") dated July 14, 1999, and amended on November 4, 1999
         (collectively,  the "Amended EnergyNorth Merger Agreement"); and (iv) a
         summary of the required  regulatory  approvals  necessary to effect the
         merger. A copy of the EnergyNorth  Merger Agreement and the EnergyNorth
         Amendment  are  appended   hereto  as  Attachments   WJF-1  and  WJF-2,
         respectively.

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,  Colonial  Gas,  Essex Gas and
         Midland Enterprises, Inc. ("Midland").

         Eastern's gas distribution  companies  consist of Boston Gas,  Colonial
         Gas and Essex Gas. In total, Eastern's gas distribution companies serve
         approximately 735,000 customers in Massachusetts. Boston Gas is engaged
         in the transportation and sale of natural gas to approximately  535,000
         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.

         Colonial Gas was  organized in 1849 under the laws of the  Commonwealth
         of Massachusetts and currently  operates in 24  municipalities  located
         northwest  of  Boston  and on  Cape  Cod.  Colonial's  service  area is
         approximately  622  square  miles  in size  and,  of its  approximately
         155,000  customers,   roughly  90  percent  are  residential  accounts.
         Colonial Gas became a wholly owned  subsidiary of Eastern on August 31,
         1999.

         Essex Gas 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.  The service  territory of
         Essex Gas is  primarily  composed  of  residential  communities  with a
         number of small commercial and diversified light industrial businesses.
         In this  service  area,  Essex Gas sells  natural gas to

<PAGE>

Page 4

         approximately  45,000  customers.  Essex  Gas  became  a  wholly  owned
         subsidiary of Eastern on September 30, 1998.

         Eastern's  unregulated  businesses  include  Midland,   Transgas,  Inc.
         ("Transgas"),  ServicEdge  Partners,  Inc.  ("ServicEdge") and AMR Data
         Corporation  ("AMR Data").  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  2,400  barges and 87  towboats.  Transgas,  acquired  as part of
         Eastern's  merger with  Colonial  Gas, is the  leading  transporter  of
         liquefied  natural gas  supplies in New England.  During 1997,  Eastern
         also formed two new  subsidiaries  to take  advantage of  opportunities
         being created by the  restructuring of the energy industry.  ServicEdge
         is a fuel-neutral,  full-service  provider of heating,  ventilation and
         air-conditioning  products  and services  and AMR Data  provides  meter
         services  primarily  to  municipal  electric,  gas and water  utilities
         throughout the Northeast.

         Eastern has formed  Merger Sub as a New Hampshire  corporation  and gas
         company  under RSA 293-A.  Merger Sub is a wholly owned  subsidiary  of
         Eastern  created for the specific  purpose of effecting the transaction
         contemplated by the merger, as described below.

Q.       Please  provide an overview of  Eastern's  planned  merger with KeySpan
         Corporation.

A.       On  November  4, 1999,  Eastern  and  KeySpan  Corporation  ("KeySpan")
         entered  into an  Agreement  and Plan of Merger  (the  "Eastern  Merger
         Agreement") under which KeySpan will acquire all of the common stock of
         Eastern for $64.00 per share in cash. The Eastern  Merger  Agreement is
         appended  hereto as Attachment  WJF-3.  As described  below,  Eastern's
         merger with  KeySpan is  conditioned  upon the  approval  of  Eastern's
         shareholders  and the Securities and Exchange  Commission  ("SEC").  In
         addition,  the  indirect  acquisition  of ENGI by KeySpan  requires the
         approval  of  the  New  Hampshire  Public  Utilities   Commission  (the
         "Commission"),  however,  the merger between Eastern and KeySpan is not
         contingent upon that approval.

III.     THE RATIONALE FOR THE ACQUISITION OF ENERGYNORTH

Q.       In general,  what are the benefits  that mergers and  acquisitions  can
         provide to utility customers?

A.       Utility  mergers  and  acquisitions   have  the  potential  to  produce
         substantial benefits to customers in the form of operational  synergies
         and cost savings that reduce  customer  rates and/or slow the growth of
         such rates.  These cost savings are  generally  not  achievable  in the
         absence of a merger or other types of 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.  Eastern's  recent  acquisitions of Colonial Gas and Essex Gas
         support this analysis in that customers of both companies are currently
         receiving  the benefit of  burner-tip  price  reductions to reflect gas
         cost  savings  achieved  through  the  mergers,  as well as  long-term,
         base-rate freezes. Specifically, Boston Gas, Colonial Gas and Essex Gas
         recently  announced gas price  reductions for residential  customers of
         4.72, 7.75, and 4.15 percent,  respectively,  for the 1999/2000 heating
         season resulting primarily from merger-related savings.

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 have been incurred to achieve
         these customer benefits, the magnitude and permanence of these benefits
         have  produced  value for  customers  that far outweigh the  associated
         one-time costs.

Q.       What  factors  played a role in the  decision by KeySpan and Eastern to
         enter into a business combination with EnergyNorth?

A.       As  competition   intensifies  and  gas  distribution  companies  fully
         unbundle at the local  level,  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, KeySpan's investment in

<PAGE>
Joint Petitioners
DG 99-
Witness:  Flaherty
December 3, 1999
Page 7

         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 growth  initiatives,  as is investment in
         new technology and infrastructure.  Because utilities,  in general, are
         characterized  by a high level of fixed  costs,  the  ability to spread
         those  fixed  costs  over  a  larger  base  of  customers  and/or  unit
         throughput to reduce prices and enhance competitiveness is critical.

         Eastern pursued a business combination with EnergyNorth because ENGI is
         a well-managed  growth  company  operating in an  economically  dynamic
         region,   just  north  of  the   service   territories   of   Eastern's
         Massachusetts-based  gas  distribution  companies.  As  a  result,  the
         increased  size and  scope of the  combined  organization  will  enable
         Eastern to provide enhanced,  cost-effective customer service, maintain
         its  competitive  position in the  marketplace  and  capitalize  on the
         above-average  growth  opportunities  for natural gas. Both Eastern and
         KeySpan believe that ENGI will be an integral  element of their overall
         operations  following the merger. As a result, the proposed combination
         with  EnergyNorth  represents a win-win  situation  for  customers  and
         shareholders.

Q.       What customer benefits do Eastern and KeySpan envision will result from
         the proposed acquisition of EnergyNorth?

A.       It is my understanding  that,  pursuant to RSA 369:8,II and RSA 374:33,
         KeySpan and Eastern must demonstrate that the merger with  EnergyNorth,
         as  provided  for  by  the  terms  of the  Amended  EnergyNorth  Merger
         Agreement,  will result in no net harm for the  customers  of ENGI.  As
         proposed  herein,  the merger of  EnergyNorth  with KeySpan and Eastern
         meets  and  exceeds  that  test.   KeySpan  and  Eastern  believe  that
         substantial  benefits for  customers  can and will be achieved and have
         structured  the  transaction  with  EnergyNorth  so as to provide  ENGI
         customers with both near- and long-term benefits.

         Significant  benefits will be available to customers because the merger
         presents unique  opportunities to ENGI for achieving economies of scale
         by operating as a sister  company to Boston Gas, Essex Gas and Colonial
         Gas, the latter of which has a service  territory that is contiguous to
         ENGI's  service  territory in southern New  Hampshire  and The Brooklyn
         Union Gas Company and KeySpan Gas East Corporation d/b/a Brooklyn Union
         of Long  Island.  As a result  of the  merger,  customers  of ENGI will
         benefit  substantially  from  increased  supply  options  and  enhanced
         purchasing   power.   The  ability  to  dispatch  across  the  combined
         distribution systems will increase flexibility, enable the optimization
         of  existing  gas-supply  resources,   encourage  and  facilitate  more
         efficient purchasing  capability and facilitate the exercise of broader
         system  control.  The  expanded  supply  portfolio

<PAGE>
Joint Petitioners
DG 99-

Page 9

         will also  increase  overall  reliability  in all service  territories.
         These gas supply  synergies are described in detail in the testimony of
         Mr. Luthern.

         In addition,  Eastern and KeySpan have made substantial  investments in
         information  technology  that may be extended to the operations of ENGI
         to enhance  its  ability to serve  customers  in a  cost-effective  and
         responsive  manner.  For  example,  Boston Gas has  developed  a Broker
         Management  System  (the  "BMS")  to  administer  its   customer-choice
         program,  as well as that of Colonial Gas and Essex Gas. As a result of
         the merger, the BMS will be available to ENGI, which will allow ENGI to
         avoid  significant  costs that would be associated  with  procuring and
         implementing  a similar system on a stand-alone  basis.  An analysis of
         the information  technology investment that ENGI would have incurred in
         the absence of the merger is set forth in the  testimony of Michelle L.
         Chicoine.

         The merger with  EnergyNorth  also presents an  opportunity  to realize
         cost  savings  as  a  result  of  reduced  operations  and  maintenance
         expenses,  i.e.,  corporate,  administrative and operational  expenses.
         These opportunities are discussed in greater detail in the testimony of
         Mr. Bodanza.  In short, the proposed merger with EnergyNorth will allow
         Eastern and KeySpan to leverage their  existing  investments to capture
         synergies that exist between the distribution  systems and to transform
         such  efficiency  gains  into  cost  savings,  lower  rates  and a more
         flexible  and  reliable   distribution  system  for  ENGI's  customers.
         Significantly,  the breadth

         and magnitude of these  benefits  would be  unavailable at a reasonable
         cost to ENGI customers in the absence of the merger.

IV.      DESCRIPTION OF THE ACQUISITION PROCESS

Q.       Please summarize the terms of the Amended  EnergyNorth Merger Agreement
         and the function of Merger Sub.

A.       Pursuant to the terms of the Amended EnergyNorth Merger Agreement,  set
         forth  in  Attachments  WJF-1  and  WJF-2,   Eastern  has  created  and
         incorporated  Merger  Sub  as  a  wholly  owned  subsidiary  under  New
         Hampshire law. Under the Amended  EnergyNorth Merger Agreement,  Merger
         Sub will merge with and into EnergyNorth, such that EnergyNorth will be
         the  surviving  corporation,  continuing as a subsidiary of Eastern and
         KeySpan under the name of "EnergyNorth, Inc." Each share of EnergyNorth
         common  stock will be  cancelled  and  extinguished  and  automatically
         converted  into  the  right to  receive  at the  effective  time of the
         merger, $61.13 in cash.

         In the event that the Eastern Merger  Agreement  expires or terminates,
         the final  value  received  by  EnergyNorth  shareholders  would not be
         determined  until  closing  since it will be a function of  shareholder
         elections of cash, shares of Eastern stock or a combination of both, as
         well as the price of Eastern  stock  during a ten-day  period  prior to
         closing.  Shareholder elections are subject to the limitation that 50.1
         percent of  EnergyNorth  shares will be exchanged for shares of Eastern

Joint Petitioners
DG 99-
Witness:  Flaherty
December 3, 1999
Page 11

         common stock with the remaining  EnergyNorth shares to be exchanged for
         cash.  In order to  ensure  that the  merger  qualifies  as a  tax-free
         reorganization,  shareholder  elections would be subject to the further
         limitation  that, in no event,  would the total value of Eastern shares
         so exchanged fall below 45 percent of the aggregate  consideration used
         to complete the  transaction.  As detailed below,  the actual number of
         Eastern  shares to be issued  would be  adjusted  through  an  exchange
         ratio.

Q.       How was the  structure of the  EnergyNorth/Eastern  merger  transaction
         affected by Eastern's planned merger with KeySpan?

A.       The merger  transaction  established in the Amended  EnergyNorth Merger
         Agreement  was  structured  to  meet  the  requirements  of a  tax-free
         reorganization  under Section  368(a) of the Internal  Revenue  Service
         Code. In a tax-free reorganization, no gain or loss would be recognized
         at the  corporate  level by  EnergyNorth,  Eastern  or Merger  Sub as a
         result of the merger,  and no gain or loss would be  recognized  by the
         individual  shareholders of EnergyNorth on the exchange of their shares
         for  shares of  Eastern  common  stock.  Shareholders  who  received  a
         combination  of cash and Eastern  stock would  recognize a gain for tax
         purposes in an amount  equal to the lesser of the cash  received or the
         total gain realized in the merger.

         Pursuant to the terms of the Eastern  Merger  Agreement,  KeySpan  will
         purchase  100  percent of the issued and  outstanding  common  stock of
         Eastern at $64 per

<PAGE>
Joint Petitioners

Witness:  Flaherty

Page 12

         share in cash. Assuming the EnergyNorth  transaction with Eastern would
         have  closed  prior to its  merger  with  Keyspan,  Eastern  would have
         delivered  a  combination  of cash and  Eastern  stock  to  EnergyNorth
         shareholders in accordance with its merger agreement.  However, the two
         transactions  would  likely  have  been  treated  for tax  purposes  as
         integrated  steps  in  a  single   transaction,   and  therefore,   the
         EnergyNorth  merger would be deemed a taxable  event and would  produce
         tax liability for both  EnergyNorth  and its  shareholders.  In view of
         Eastern's  pending  agreement  with  KeySpan,  Eastern and  EnergyNorth
         agreed to  restructure  their  original  agreement to  accommodate  the
         provisions of the Eastern Merger Agreement.

Q.       What is the nature of the  investment  required to attain the  benefits
         associated with this acquisition?

A.       As described in greater  detail in the  testimony of Mr.  Bodanza,  the
         investment  required to obtain the benefits  associated  with Eastern's
         acquisition  of  EnergyNorth  is  represented  by three  categories  of
         merger-related  costs: (1) costs incurred to achieve the synergies that
         will  ultimately  reduce  the  cost  of  ENGI's  operations;   (2)  the
         transaction  costs incurred in developing,  executing and obtaining the
         necessary  agreements and approvals for the merger; and (3) the cost to
         Eastern's shareholders for the acquisition, i.e., the premium over book
         value  received  by  EnergyNorth  shareholders.  As  described  by  Mr.
         Bodanza,  transaction costs and  merger-integration  costs in this case
         are estimated to be $22.2 million.

Page 13

Q.      What will be the acquisition premium that results from this transaction?

A.       The acquisition  premium is calculated by taking the difference between
         ENGI's book value per share at closing and the purchase price of $61.13
         per share,  and  multiplying  this  difference  by the number shares of
         EnergyNorth  common  stock  issued and  outstanding  as of the closing.
         Using  EnergyNorth's  book  value as of June 30,  1999,  and a total of
         3,319,712 issued and outstanding shares, a premium of $147 million will
         be paid,  including  $23  million  for the  portion of the  acquisition
         premium attributable to EnergyNorth's non-utility affiliates,  based on
         a fair market valuation.  Excluding  transaction and integration costs,
         an up-front  acquisition  premium of approximately $124 million will be
         paid  to  accomplish  the   acquisition  of   EnergyNorth's   regulated
         gas-distribution business.

         In calculating the impact of the payment of the acquisition  premium on
         earnings,  an important  consideration  is that the transaction must be
         recorded  on  the  books  of  the  acquired  companies  using  purchase
         accounting,  and therefore,  the  acquisition  premium for ENGI will be
         amortized  over 40  years as an  annual  non-tax-deductible  charge  to
         earnings of approximately  $3.1 million.  In order to achieve after-tax
         earnings sufficient to recover the amortized amount, it is necessary to
         "gross-up"  the $3.1  million  charge by a tax factor of  1.6722.  On a
         gross-up basis,  synergies of approximately  $5.2 million would need to
         be retained  annually by

<PAGE>
Joint Petitioners
DG 99-
Witness:  Flaherty
December 3, 1999
Page 14

         shareholders  to  offset  the  negative  impact  of these  costs on the
         earnings of the post-merger company.

Q.       What is the rationale for the purchase price of $61.13 per share as set
         forth in the Amended EnergyNorth Merger Agreement?

A.       Eastern and EnergyNorth  renegotiated  the terms of their July 14, 1999
         merger  agreement  in order to  accommodate  the  terms of the  Eastern
         Merger  Agreement,  which  converted  the  transaction  to an  all-cash
         transaction.  Attachment  WJF-4 presents the calculation and outcome of
         the renegotiated agreement with regard to the per-share purchase price,
         as described below.

         In order to consummate  the merger  transaction  under the terms of the
         original  merger  agreement  entered into by Eastern and EnergyNorth on
         July  14,  1999,  each  share  of  EnergyNorth  common  stock  would be
         converted into a combination of cash and shares of Eastern common stock
         in accordance  with an exchange ratio.  The original  merger  agreement
         established  a  floating  exchange  ratio to  ensure  that  EnergyNorth
         shareholders would receive a value of $47.00 per share, if the value of
         Eastern's  shares ranged from $36.00 to $44.00 at closing.  Pursuant to
         section 1.6(a)(i) of the original merger agreement,  the exchange ratio
         would be established by dividing the per share cash amount of $47.00 by
         the market  value of  Eastern's  common  stock,  based upon the average
         market price of Eastern shares during a specified  ten-day period prior
         to closing.

<PAGE>
Joint Petitioners
DG 99-
Witness:  Flaherty
December 3, 1999
Page 15

         Thus,  if the average  market  value of  Eastern's  shares were to fall
         between $36.00 and $44.00 per share during the relevant period prior to
         closing,  shares of  EnergyNorth  common stock would be exchanged for a
         number of shares of Eastern  common stock pursuant to an exchange ratio
         ranging from 1.30556 to 1.06818,  which would adjust to produce a value
         of $47.00 per share for EnergyNorth shareholders. In the event that the
         market  value of Eastern's  shares was less than $36.00 per share,  the
         exchange  ratio  would be fixed at  1.30556,  and in the event that the
         market value of Eastern's shares was greater than $44.00 per share, the
         exchange ratio would be fixed at 1.06818. Because the exchange ratio is
         fixed at $36.00 and $44.00 per share, the value received by EnergyNorth
         shareholders  could be greater or less than $47.00, if the market value
         of  Eastern's  stock were to be above $44.00 or below $36.00 on average
         ten days prior to closing.

         On November 4, 1999, Eastern announced that it had reached an agreement
         with KeySpan under which  KeySpan would  purchase all of the issued and
         outstanding  common  stock of  Eastern  at  $64.00  per  share in cash.
         Consequently,  by virtue of the exchange ratio  provisions set forth in
         the  original   Eastern/EnergyNorth   merger   agreement,   EnergyNorth
         shareholders  would receive  1.06818  shares of Eastern common stock in
         exchange  for each share of  EnergyNorth  common  stock,  or $57.70 per
         share (assuming 49.9 percent of the  outstanding  shares of EnergyNorth

<PAGE>
Joint Petitioners
DG 99-
Witness:  Flaherty
December 3, 1999
Page 16

         common stock would be exchanged  for cash and the  remainder  exchanged
         for shares of Eastern common stock). As a result of Eastern's agreement
         with  KeySpan,  EnergyNorth's  merger  would  no  longer  qualify  as a
         tax-free  reorganization.  Thus, in  renegotiating  the original merger
         agreement to accommodate  Eastern's  pending  arrangement with KeySpan,
         EnergyNorth  sought  additional  compensation,  in  part,  for  the tax
         liability  that  shareholders  would  now  incur  as a  result  of  the
         transaction with KeySpan.

         The  negotiation  of this and other issues  resulted in an agreement to
         set the per-share cash  consideration at a value equal to that produced
         using the  exchange  ratio of 1.175,  which would have  applied had the
         value of Eastern's common stock remained at the mid-point of the collar
         range of $36.00 to $44.00 per share,  i.e.,  at $40.00 per share.  As a
         result,  EnergyNorth  shareholders will receive $61.13 per share, which
         equals $64.00 per share times the exchange  ratio of 1.175  (calculated
         using  the   assumption   that  no  more  than  49.9   percent  of  the
         consideration   would  have  been  paid  in  cash  absent  the  KeySpan
         transaction).

Q.       Is ENGI seeking recovery of the merger-related costs at this time?

A.       ENGI is not seeking  recovery of  merger-related  costs in this filing.
         ENGI will seek recovery of  merger-related  costs in the future only to
         the extent that it is able to demonstrate that such costs are offset by
         the savings achieved as a result of the merger. It is our understanding
         that this is  consistent  with the  Commission's
<PAGE>
Joint Petitioners
DG 99-

Page 17

         approach  in  another  gas-utility  merger  case,  i.e.,  Re:  Northern
         Utilities,  Inc.,  Docket  No.  DF  98-040,  Order  No.  22,983  (1998)
         ("Northern Utilities"), where the Commission approved a settlement that
         required  the  petitioners  to  substantiate  any savings to  customers
         resulting  from the merger  before  affording the  acquisition  premium
         ratemaking  treatment.  Although approved as a condition to settlement,
         the  Commission's  rulings  in the  Northern  Utilities  case  provided
         important guidance to the Joint Petitioners in structuring the proposed
         merger.

         Specifically, in agreeing to a plan of merger with EnergyNorth, Eastern
         carefully  evaluated the opportunities  for achieving  efficiencies and
         cost savings in  coordinating  and  integrating  the operations of ENGI
         with those of its other gas  distribution  operations.  Thus, the price
         agreed to by Eastern, and subsequently by KeySpan, is a function of the
         synergies  that would be  available as a result of the merger to offset
         the costs  incurred in effecting  the merger.  Eastern and KeySpan have
         pursued  the  merger  with   EnergyNorth   based  on  the  Commission's
         willingness   to  approve  a  settlement   that  allowed  a  reasonable
         opportunity  to  recover  merger-related  costs,  where  merger-related
         savings could be substantiated to support such recovery.

         Accordingly, in this proceeding, Eastern and KeySpan seek only a ruling
         by the Commission  that approval of the merger is without  prejudice to
         ENGI's right to request recovery of  merger-related  costs, in a future
         proceeding,  and to have the

Page 18


         reasonable  opportunity to recover such costs, if ENGI  demonstrates to
         the  Commission's  satisfaction  that  merger-related  savings equal or
         exceed those costs.  Eastern and KeySpan are aware that the  Commission
         is   concerned   that  the   identification   and   quantification   of
         merger-related  savings in a future  proceeding  would be  difficult to
         accomplish, and that in any such proceeding, the Commission may be at a
         disadvantage  with regard to available  data relating to the attainment
         of such savings. Therefore,  Eastern and KeySpan will commit to working
         with  the  Staff  of the  Commission  and the  Office  of the  Consumer
         Advocate to establish a mechanism for measuring cost savings that could
         be  used  to  offset  merger-related  costs.  Such  a  mechanism  would
         facilitate  a  demonstration  of the extent to which cost  savings have
         been achieved as a result of the merger.

Q.       Is   consummation   of  the  merger  between  Eastern  and  EnergyNorth
         contingent upon the approval of the Commission in the manner  described
         above?

A.       Yes.  Article  6.1(b)  of  the  Amended  EnergyNorth  Merger  Agreement
         provides  that,  with  regard  to  rates  and  the  recovery  of  costs
         associated  with the merger  (including  the  acquisition  premium  and
         transaction  and  integration  costs),  the  Commission's  approval  is
         required  upon terms and  conditions  that are no less  favorable  than
         those set  forth by the  Commission  pursuant  to  Northern  Utilities.
         Accordingly,  Eastern  and  KeySpan  will  not  move  forward  with the
         EnergyNorth merger without the Commission's  approval of their proposal
         to have a reasonable

Page 19

         opportunity to recover  merger-related costs if merger-related  savings
         are demonstrated to equal or exceed those costs.

         As a policy  matter,  we believe that  industry  consolidation  through
         mergers and acquisitions  should be encouraged where such consolidation
         will lower the cost of utility service for customers. Our proposal will
         achieve  this  result  for  ENGI's  customers.  In  fact,  KeySpan  and
         EnergyNorth are uniquely  positioned to provide significant and lasting
         benefits  to   customers   given  the   proximity  of  our  systems  to
         EnergyNorth,  as well as the  ability of Eastern and KeySpan to achieve
         synergies and avoid  technology  investments on ENGI's  system.  At the
         same time,  substantial costs,  including the acquisition premium, must
         be  incurred by  shareholders  to effect  such a  transaction.  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  Commission  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 Commission allow, in
         some  reasonable  manner,  an  opportunity  for  the  recovery  of  the
         investment  that was necessary to obtain real and lasting  benefits for
         ENGI customers.

Q.       In  summary,  how does  the  merger  proposal  set  forth by the  Joint
         Petitioners result in no net harm to customers?

A.       The Joint  Petitioners'  merger  proposal will result in no net harm to
         customers  for  the  following  reasons:  (1) the  continued  corporate
         existence of ENGI,  including  the  maintenance  of separate  books and
         records,   will  facilitate  the  Commission's   continued  review  and
         oversight  of ENGI and its  operations  in New  Hampshire;  (2) a Local
         Advisory Board  comprised of not less than five members,  to be chaired
         by Robert R.  Giordano,  will be  established  following  the merger to
         provide  counsel to Eastern and  KeySpan;  (3) the  structure of ENGI's
         operations  will  not  change  as  a  result  of  the  merger;  (4)  no
         determination  is  sought  in this  proceeding  regarding  the  capital
         structure  to be  used in any  future  proceeding;  and  (5) the  Joint
         Petitioners will be required to substantiate savings resulting from the
         merger before seeking  consideration of merger-related cost recovery in
         a future proceeding.

         Moreover,  the Joint Petitioners propose: (1) to provide customers with
         immediate   gas-cost  savings   estimated  to  produce  a  2.2  percent
         burner-tip  price  reduction;  and (2) to develop with the Commission a
         mechanism for identifying and quantifying
<PAGE>
Joint Petitioners
DG 99-
Witness:  Flaherty
December 3, 1999
Page 21

         other cost savings  achievable only as a result of the merger.  Because
         Eastern  would,  in a future  proceeding,  request that the  Commission
         allow   recovery  of   merger-related   costs  only   through   savings
         demonstrated  to result from the merger,  such recovery would not cause
         rates to be any  higher  for  customers  than what they would have been
         without the merger. At the same time, ENGI's customers will receive the
         benefit  of a  burner-tip  price  reduction  achieved  as a  result  of
         gas-supply synergies. Thus, the proposed merger results in net benefits
         to customers, and therefore,  meets and exceeds the Commission's no net
         harm standard.

Q.       Specifically,  how will the merger  affect the  corporate  structure of
         ENGI or the Commission's jurisdiction over its operations?

A.       The structure of ENGI's  operations  will not change as a result of the
         merger and the Commission's  jurisdiction with respect to the company's
         operations will remain  unaltered.  ENGI, will continue to operate as a
         New Hampshire  corporation  subject to the Commission's full regulatory
         authority.  Thus, the Commission's jurisdiction over rates, service and
         other matters of ENGI, will not be affected by the merger.

         Following  the  merger,   EnergyNorth's  headquarters  will  remain  in
         Manchester,  New Hampshire and the terms of all  collective  bargaining
         agreements  will be fulfilled.  Eastern has also  committed to maintain
         charitable  contributions  to communities  served by EnergyNorth  and a
         level of  involvement  in community

Page 22

         activities as carried on in recent years by  EnergyNorth.  In addition,
         Eastern will establish a local  advisory  board  consisting of not less
         than five members, to be chaired by Robert R. Giordano, for a period of
         at least three years  following the merger.  Membership on the advisory
         board will be offered to all current  members of the Board of Directors
         of EnergyNorth  who are residents of the State of New  Hampshire.  This
         will provide  Eastern and KeySpan with access to the advice and counsel
         of  EnergyNorth's  directors  for at least  three years  following  the
         merger.  As addressed in the  testimony of Craig G.  Matthews,  none of
         these  commitments  will  change as a result of  Eastern's  merger with
         KeySpan.

V.       REGULATORY APPROVALS REQUIRED

Q.       What regulatory approvals are required for completion of the merger?

A.       In  addition  to  the  Commission's  approval  of  the  acquisition  of
         EnergyNorth,  Eastern  must obtain the approval of the  Securities  and
         Exchange  Commission for the acquisition by Eastern of the common stock
         of EnergyNorth  pursuant to the Public Utility  Holding  Company Act of
         1935. In addition,  under 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 United States  Department of Justice may review any
         antitrust  issues  that  are  raised  by  the  merger.  The  regulatory
         approvals that are required for

Page 23

         completion  of KeySpan's  acquisition  of Eastern are  discussed in the
         testimony of Craig G. Matthews.

Q.       What are the specific approvals requested of the Commission?
A.       Eastern and KeySpan request that the Commission:

         (1)      Accept their representation  pursuant to RSA 369:8,II, or rule
                  under RSA  374:33,  that the  merger  between  Merger  Sub and
                  EnergyNorth,  as  provided  for by the  terms  of the  Amended
                  EnergyNorth  Merger  Agreement,  meets the Commission's no net
                  harm test for  determining  that the merger is consistent with
                  the public interest; and

         (2)      Rule that such  approval is without  prejudice to ENGI's right
                  to  request  recovery  of  merger-related  costs,  in a future
                  proceeding,  and the  reasonable  opportunity  to recover such
                  costs, to the extent that substantiated merger-related savings
                  meet or exceed such costs.

Q.       Does this conclude your testimony?

A.       Yes, it does.

                             STATE OF NEW HAMPSHIRE

                           PUBLIC UTILITIES COMMISSION

                         Testimony of Joseph F. Bodanza

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 02109.

Q.       By whom are you employed and in what capacity?

A.       I am Senior  Vice  President  and  Treasurer  of  Eastern  Enterprises'
         ("Eastern") local distribution  company operations in Massachusetts.  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.  I am also a director  of Boston  Gas  Company
         ("Boston Gas"), Colonial Gas Company ("Colonial") and Essex Gas Company
         ("Essex Gas")

Q.       Have you previously testified before any regulatory commission?

A.       Yes. As an officer and employee of Boston Gas for over 27 years, I have
         testified in numerous  proceedings before the Massachusetts  Department
         of Telecommunications  and Energy (the "Department").  Most recently, I
         testified

         before the Department in Eastern-Essex Acquisition, D.T.E. 98-27 (1998)
         and Eastern-Colonial Acquisition, D.T.E. 98-128 (1999).

Q.       Are you familiar with the proposed acquisition of EnergyNorth,  Inc. by
         Eastern Enterprises?

A.       Yes. Eastern and KeySpan Corporation  ("KeySpan") have requested that I
         evaluate   and   analyze   the   operations   of   EnergyNorth,    Inc.
         ("EnergyNorth")  and its principal  operating  subsidiary,  EnergyNorth
         Natural  Gas,  Inc.  ("ENGI").  In that  regard,  I have  analyzed  the
         opportunities to achieve efficiencies in the operations of ENGI through
         coordination  and  integration  with the  operations  of Eastern's  gas
         distribution subsidiaries, Boston Gas, Colonial Gas and Essex Gas. I am
         also working with KeySpan to perform a similar analysis for the purpose
         of identifying  further  opportunities  for cost savings as a result of
         KeySpan's acquisition of Eastern's operations.

Q.       What is the purpose of your testimony?

A.       The purpose of my  testimony  is: (i) to review the  benefits and costs
         associated  with the  proposed  merger;  and (ii) to  describe  how the
         proposed merger meets and exceeds the "no net harm" test.

II.      DISCUSSION OF COSTS AND BENEFITS

Q.       Would you review the overall  benefits of the merger to ENGI  customers
         and shareholders?

A.       Eastern's strategy in pursuing a business  combination with EnergyNorth
         is to  build  upon its core  gas  distribution  operations  in order to
         create  economies  of  scale  that  will  enable  it  to  increase  gas
         throughput,  improve  productivity,  control costs and enhance  service
         quality for customers.  In achieving these objectives,  Eastern will be
         in a position to provide  significant  benefits to ENGI's customers and
         EnergyNorth's  shareholders.  The  benefits  that will be  created  for
         ENGI's  customers as a result of Eastern's  acquisition of EnergyNorth,
         and in turn,  KeySpan's  acquisition  of Eastern,  include lower costs,
         improved  efficiency  and enhanced  customer  service.  These  customer
         benefits will be direct and permanent.  For instance, in developing the
         merger plan,  we have  determined  that we can provide an immediate 2.2
         percent  reduction in the total  burner-tip price of gas currently paid
         by ENGI's customers.

         In  addition,  as a result of the merger,  employees  of ENGI will have
         access to employment  opportunities  within a larger,  more diversified
         organization and will experience a more dynamic working environment. In
         that regard, Eastern has hosted informational sessions and job fairs to
         make  employees  aware of  employment  opportunities  within  Eastern's
         organization.  This  process has worked

<PAGE>
Joint Petitioners

Witness:  Bodanza
December 3, 1999
Page 4

         well in bringing employees of Colonial Gas and Essex Gas into Eastern's
         organization.

         Lastly,  the proposed merger will provide  EnergyNorth's  shareholders,
         many of whom are New Hampshire residents and ENGI customers,  with fair
         value for their ownership interest.

Q.       How do KeySpan and Eastern plan to achieve a burner-tip price reduction
         to customers of ENGI of approximately 2.2 percent?

A.       As described in the testimony of Mr.  Luthern,  we have identified cost
         savings for ENGI's  customers of  approximately  $2.0 million that will
         result from the  attainment  of synergies and  efficiencies  in the gas
         supply  function.  Based on total  weather-normalized  gas  revenues of
         approximately  $90.5 million,  the price  reduction  provided to ENGI's
         customers  will be  approximately  2.2 percent.  All  gas-cost  related
         savings will be reflected in ENGI's Cost of Gas ("CoG") rates.

Q.       On what basis have you  determined  that cost savings of  approximately
         $2.0  million  will be  attained  as a result of  synergies  in the gas
         supply function?

A.       We have determined  that gas cost savings will be achieved  through the
         coordination  and integration of the gas supply  resources of ENGI with
         those of  Eastern's  other  gas  distribution  operations.  Such  joint
         planning will increase supply options, result in the more efficient use
         of existing resources, and generate savings from an enhanced purchasing
         power.  Mr.  Luthern  has  reviewed  the  gas-

<PAGE>
Joint Petitioners
DG 99-
Witness:  Bodanza
December 3, 1999
Page 5

         resource  portfolio and  gas-supply  operations of ENGI to identify and
         quantify potential synergies and has determined that approximately $2.0
         million  in gas cost  savings  will be  attainable  in the  first  year
         following  the  merger.  These  types of savings  are  detailed  in Mr.
         Luthern's testimony and, in our experience, are likely to represent the
         minimum level of gas-cost savings  available as a result of the merger.
         Moreover,  as addressed  in the  testimony  of Craig G.  Matthews,  the
         potential to achieve additional  synergies may be increased as a result
         of Eastern's  planned merger with KeySpan.


Q.       Have Eastern's mergers with Colonial Gas and Essex Gas produced similar
         gas-cost savings for customers?

A.       Eastern's  mergers  with  Colonial  Gas and  Essex  Gas  have  produced
         significant  and immediate  cost savings for  customers.  Specifically,
         just after the merger with Eastern,  Essex Gas  customers  received the
         benefit of a 5 percent  reduction in their burner-tip price as a result
         of the release of  long-haul  pipeline  capacity on the  Tennessee  Gas
         Pipeline and the  renegotiation of certain commodity  contracts,  which
         were initiatives that would not have been available to Essex Gas in the
         absence of the merger. Similarly, Colonial Gas customers will receive a
         2.2 percent burner-tip price reduction in the first full year following
         the merger  resulting from the release of redundant  capacity and other
         gas-supply  initiatives  made possible by the merger with  Eastern.  In
         addition,  as a result of the

         consolidation of the resource portfolios of the three companies, Boston
         Gas has negotiated  substantial  changes to the overall  portfolio that
         have  produced  savings  over and above those  projected  in the merger
         filings approved by the Department.

         Furthermore, on October 15, 1999, the Department approved a petition by
         Boston   Gas,   Colonial   Gas  and   Essex   Gas  to   enter   into  a
         portfolio-management arrangement with El Paso Energy Marketing Company,
         a  wholesale   marketer,   which  will  manage  the  combined  upstream
         transportation  capacity  resources of the  companies  for a three-year
         period commencing  November 1, 1999.  Because of the economies of scale
         inherent in the combined  portfolio,  the companies were able to secure
         significant value for the management rights,  which are being passed on
         to customers of all three companies. Thus, the combination of projected
         merger  savings,   additional  savings  resulting  from  the  portfolio
         restructuring  and the cost  reductions  that will occur as a result of
         the portfolio-management  arrangement will provide significant benefits
         to customers.

         It is Eastern's objective to achieve the same types of cost savings for
         the customers of ENGI by incorporating the gas-supply resources of ENGI
         into the combined  portfolio of Eastern's gas distribution  operations.
         Moreover, additional savings opportunities may be available as a result
         of Eastern's planned merger with KeySpan.

Q.       Have you  considered  the  potential for any cost savings that could be
         realized through operational efficiencies?

A.       Yes. Prior to reaching  agreement with EnergyNorth on a plan of merger,
         Eastern  commenced  a process  to  evaluate  integration  opportunities
         between ENGI and its existing gas distribution  companies,  Boston Gas,
         Colonial Gas and Essex Gas. A similar process was undertaken by KeySpan
         in evaluating a potential business  combination with Eastern.  In fact,
         Eastern's  willingness  to pay a  price  in  excess  of book  value  to
         accomplish  the merger was based on its  assessment  that cost  savings
         could be  achieved  to offset  the  investment  required  to effect the
         transaction,  and that such investment would reduce costs for customers
         over the long term.

         Since  entering into the plan of merger with  EnergyNorth,  Eastern has
         undertaken  a  more  comprehensive   process  to  analyze   integration
         opportunities  and KeySpan will  commence a similar  process to analyze
         and  identify,   to  the  extent   possible,   additional   integration
         opportunities  stemming from its merger with Eastern.  The objective of
         these  efforts is, and will continue to be, to define and implement the
         business  processes  for the  companies  to  operate  with  the  utmost
         efficiency.  We expect that, over time, the significantly  larger scale
         of Eastern's operations, both in financial and operational terms, would
         be an important  factor in enhancing the efficiency and  reliability of
         the combined distribution system. Eastern's planned
<PAGE>

         merger  with  KeySpan  will only add to  Eastern's  ability  to achieve
         operational  efficiencies and economies of scale, which ultimately will
         lower costs to customers.

Q.       Have you quantified the potential  near-term cost savings that could be
         realized through operations and maintenance efficiencies?

A.       As a result of the merger, ENGI will be able to achieve cost reductions
         in the corporate and  administrative  areas through the  elimination of
         redundant job functions. Specifically, the proposed merger will provide
         an  opportunity  to  consolidate   finance,   accounting,   information
         services,  marketing, human resources, public and shareholder relations
         and gas supply  activities.  We estimate that such  consolidation  will
         result in the reduction of 62 positions, including 47 management and 15
         non-management  positions. We further estimate that the direct wage and
         salary cost reductions associated with these positions is approximately
         $3.3  million  annually.  We also  estimate  that  the  elimination  of
         employee  benefits   associated  with  these  positions  would  produce
         approximately $900,000 of additional annual cost savings.

         Moreover, the integration of corporate and administrative  functions is
         expected  to  reduce  non-labor  costs by  approximately  $1.5  million
         annually  through  the  consolidation  of  overlapping  or  duplicative
         programs and  expenditures  relating to  insurance,  employee  benefits
         administration,   audit  and  consulting  fees,  shareholder  services,
         information-systems expenses, advertising,  vehicle expense, legal fees
         and
<PAGE>

Page 9


         banking and financing  costs.  Such cost savings will be available only
         because of the merger and the resulting  ability to coordinate  certain
         corporate  governance  activities  that are common to the operations of
         ENGI and Eastern's gas distribution operations. Therefore, in total, we
         estimate that  operations and  maintenance  ("O&M")  expense savings of
         $5.7 million annually are potentially  attainable in the near term as a
         result of the  acquisition  of ENGI.  Although not  quantified  as yet,
         incremental savings of a similar nature may be available as a result of
         Eastern's merger with KeySpan.

         In addition, the information technology employed by Eastern and KeySpan
         will provide an important  tool for increasing the efficiency of ENGI's
         operations.  Both  organizations  have made significant  investments in
         information technology,  including software applications,  hardware and
         infrastructure,  which will be extended to the  operations of ENGI as a
         result of the merger. These investments have enhanced customer service,
         improved  productivity and enabled the  implementation of comprehensive
         customer-choice programs. Combining the information processing needs of
         ENGI with the gas  distribution  operations of Eastern and KeySpan will
         enable EnergyNorth to avoid incurring duplicate expenditures. ENGI will
         be able to avoid planned development and/or modification of a number of
         systems, including: (1) software to automate the dispatch function; (2)
         an enterprise  level reporting and data  warehousing  system to

<PAGE>

         enhance  management  reporting;  (3) an upgrade of the telephone system
         and call center;  (4) an upgrade of the  infrastructure  to accommodate
         internet/intranet applications; (5) software for payroll/human resource
         functions;  (6) software and  conversion  costs to automate the mapping
         functions;  (7) development  and  implementation  of  disaster-recovery
         capability;  (8) modifications to existing customer  information-system
         and gas-supply  systems to expand the customer choice program;  and (9)
         replacement of the customer-information  system. As described in detail
         in the testimony of Ms.  Chicoine,  ENGI would have  incurred  costs of
         approximately  $4.3 million on a stand-alone  basis to implement and/or
         modify these necessary systems.

Q.       What  factors  may affect  the  attainment  of cost  savings in the gas
         distribution operation of ENGI?

A.       The attainment of  efficiencies  in ENGI's gas  distribution  operation
         hinges  upon  the  successful  implementation  of a  merger-integration
         process  to  manage  the   coordination   and  integration  of  various
         functional areas. The primary objective of this process is to determine
         the  appropriate  level of  integration of systems,  support  services,
         customer  inquiry  and  accounting,   collection  and   billing-related
         services necessary to provide  cost-effective  service, while producing
         labor and non-labor cost savings.  However,  it is difficult to predict
         how successful and comprehensive the integration of certain elements of
         ENGI's  operations with those of Eastern's
<PAGE>
Joint Petitioners
DG 99-

Page 11

         gas  distribution  operations  will be, and  therefore,  there are some
         uncertainties involved in achieving these cost reductions

         As discussed above, we have estimated that  approximately  $5.7 million
         in annual O&M synergies  will be available as a result of the merger to
         offset  the cost of the  merger  incurred  by  shareholders.  Given the
         uncertainties associated with the attainment of O&M synergies, however,
         Eastern and KeySpan are assuming the risk of achieving  recovery of the
         costs incurred to effect the merger.

Q.       What is Eastern's plan for maintaining the operations of ENGI following
         the merger?

A.       As indicated in the testimony of Mr.  Flaherty,  ENGI will operate as a
         sister company to Boston Gas,  Colonial Gas and Essex Gas following the
         merger with Eastern,  and to The Brooklyn Union Gas Company and KeySpan
         Gas East  Corporation  d/b/a  Brooklyn  Union of Long Island  following
         Eastern's merger with KeySpan.  As Eastern has done in the mergers with
         Colonial Gas and Essex Gas,  Eastern will maintain the  headquarters of
         ENGI, which are currently housed in Manchester,  New Hampshire, as well
         as various  field  operations  currently  operated  by ENGI.  Moreover,
         KeySpan and Eastern are committed to continuing the level of investment
         required  to  maintain  and  extend  the  distribution  system of ENGI.
         Pursuant to the merger agreement,  Eastern will establish a five-member
         Local  Advisory  Board to provide  input into the  operations  of ENGI.
         Moreover, as

<PAGE>
Joint Petitioners
DG 99-
Witness:  Bodanza

Page 12

         addressed in the testimony of Craig G. Matthews,  Eastern's commitments
         with  regard to the  operations  of ENGI  following  the merger will be
         affirmed by KeySpan following the merger.

Q.       Are there costs  associated with achieving the merger benefits for ENGI
         customers?

A.       Eastern and KeySpan will incur the  following  merger-related  costs in
         order to  accomplish  the  transaction:  (1) merger  integration  costs
         incurred to achieve the synergies that will ultimately  reduce the cost
         of ENGI's  operations;  (2) transaction costs related to the completion
         of the merger transaction;  and (3) the acquisition premium, which will
         be  recorded  as  goodwill  on the  books  of ENGI in  accordance  with
         Generally Accepted Accounting Principles ("GAAP").

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 ENGI's  operations  into those of
         Eastern's  and  KeySpan's  gas  distribution  operations.  These  costs
         include   employee   separation  costs  incurred  to  reduce  redundant
         positions,  systems  conversion  and  consolidation  costs required for
         efficient  operations,  customer and employee  communication  costs and
         similar costs necessary to support the  merger-integration  process. An
         itemization  of these  costs  totaling  $14.4  million  is set forth in
         Attachment JFB-1.

<PAGE>
Joint Petitioners
DG 99-
Witness:  Bodanza
December 3, 1999
Page 13

         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 costs totaling $7.8 million is set forth in Attachment JFB-2.

         The third category of merger costs relates to the  acquisition  premium
         required to make available the lower rates and cost savings that result
         from the merger. The acquisition  premium is discussed in detail in Mr.
         Flaherty's  testimony  and is  estimated  to total  approximately  $124
         million for  EnergyNorth's  regulated gas  operations.  The acquisition
         premium is a necessary investment because it results in the creation of
         a more efficient operation that will produce cost-saving  opportunities
         and lower rates to customers.  The payment of an  acquisition  premium,
         however,  has an  unavoidable  impact on the earnings of the  acquiring
         company.

         In  a  purchase-accounting  transaction,  the  acquisition  premium  is
         recorded on the books of the acquired company and amortized as a direct
         charge to earnings. Because the acquisition of ENGI requires the use of
         purchase  accounting,  the acquisition  premium will be recorded on the
         books of ENGI and amortized as a $3.1 million annual charge to earnings
         over a 40-year  period.  This charge to

<PAGE>
Joint Petitioners
DG 99-
Witness:  Bodanza
December 3, 1999
Page 14

         earnings is not tax  deductible,  and  therefore,  it is  necessary  to
         "gross-up"  this amount by a tax factor of 1.6722 to achieve  after-tax
         earnings  sufficient  to cover this cost and to reimburse  shareholders
         for their  investment.  On a gross-up basis, cost savings and synergies
         of approximately  $5.2 million  annually over the 40-year  amortization
         period must be realized to offset the impact of this cost on  earnings,
         as set forth in Attachment  JFB-3.  As indicated in  Attachment  JFB-4,
         merger-integration  costs and transactions costs would be amortized for
         ratemaking purposes over a ten-year period.

Q.       Is ENGI seeking to recover these merger-related costs in this filing?

A.       As  discussed  above,  Eastern and KeySpan are  incurring  the costs to
         complete the transaction  with EnergyNorth in order to attain economies
         of scale within the gas distribution operations,  which will ultimately
         reduce costs for ENGI's customers. Notwithstanding this fact, ENGI will
         seek recovery of the remaining  unamortized balance of these costs in a
         future  proceeding only to the extent that it can demonstrate that such
         costs are offset by the  savings  achieved  as a result of the  merger.
         Accordingly,  in this proceeding,  Eastern and KeySpan seek a ruling by
         the Commission that any determination  made with regard to the approval
         of the  merger is without  prejudice  to ENGI's  right to request  such
         recovery  in  a  future  proceeding,  where  it  is  demonstrated  that
         merger-related  savings  will  equal or exceed  those  costs.  It is my
         understanding that this is consistent with the
<PAGE>
Joint Petitioners
DG 99-
Witness:  Bodanza
December 3, 1999
Page 15

         Commission's  approach in another gas-utility merger case, Re: Northern
         Utilities,   Docket   No.  DF   98-040,   Order  No.   22,983   (1998).

         Eastern and KeySpan recognize that the Commission is concerned that the
         identification and quantification of merger-related savings in a future
         proceeding  will be  difficult  to  accomplish,  and  that in any  such
         proceeding,  the  Commission  may be at a  disadvantage  with regard to
         available data relating to the attainment of merger savings. Therefore,
         Eastern  and KeySpan  propose to work with the Staff of the  Commission
         and  the  Office  of the  Consumer  Advocate  ("OCA")  to  establish  a
         mechanism  for  measuring  cost  savings  that  could be used to offset
         merger-related  costs.  This  mechanism  would serve as a proxy for the
         cost to serve  that  would  exist in the  absence  of the  merger,  and
         therefore, would facilitate a demonstration of the extent to which cost
         savings  have been  achieved as a result of the  merger.  To the extent
         that ENGI seeks  recovery of  merger-related  costs in the future,  the
         Commission would have a mechanism in place for determining the level of
         savings  available  as a  result  of the  merger.  In  Eastern-Colonial
         Acquisition, D.T.E. 98-128 (1999), Eastern proposed, and the Department
         approved, a mechanism of this type to measure savings for cost recovery
         purposes. This, or a similar mechanism, may address the concerns raised
         in New Hampshire with regard to the  identification  and quantification
         of  merger-related  savings,  and we look

Page 16

         forward  to  working  with  the  Commission  and the OCA to  develop  a
         workable solution for these concerns.

Q.       What  rationale  do you have for seeking  recovery  of the  acquisition
         costs  to the  extent  that  such  costs  are  offset  by  demonstrated
         merger-related savings?

A.       KeySpan,  Eastern and ENGI strongly  believe that there are substantial
         synergies  and cost  savings  that will result  from the  merger.  That
         belief,  in fact,  serves  as the  primary  motivating  factor  for the
         shareholder  investment in this proposal.  Eastern is uniquely situated
         to provide  ENGI's  customers  with  substantial  benefits  because the
         service   territories  of  ENGI  and  Colonial  Gas  (Merrimack  Valley
         Division) are  geographically  contiguous and because ENGI's  corporate
         and  administrative  functions can be coordinated  and integrated  with
         those of Boston Gas. At the same time,  as  discussed  above and in the
         testimony of Mr. Flaherty,  there are substantial costs associated with
         accomplishing this transaction.  In order to effect the transaction and
         to attain the resultant benefits for customers,  shareholders must make
         a  substantial  investment  with the  expectation  that there will be a
         reasonable  opportunity  to recover  merger-related  costs.  Thus,  the
         customer benefits available as a result of the merger are possible only
         if the Commission  recognizes  that there is a direct  linkage  between
         these  benefits  and the  investment  necessary to bring them about and
         provides a reasonable opportunity for shareholders to recover the costs
         of  the  acquisition.  In  the  absence  of a  regulatory  policy  that
         recognizes,  in

<PAGE>
Joint Petitioners
DG 99-
Witness:  Bodanza
December 3, 1999
Page 17

         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 the transaction.

III.     THE MERGER'S CONSISTENCY WITH THE PUBLIC INTEREST STANDARD

Q.       Is the merger  consistent  with the "no net harm"  test  applied by the
         Commission when reviewing merger transactions?

A.       Yes.  The  proposed  merger  meets  and  exceeds  the no net harm  test
         articulated by the Commission.  In New England Electric, the Commission
         stated  that the  mandate  in RSA  369:8  that  the  merger  will  "not
         adversely affect the rates, terms,  service, or operation of the public
         utility  within the state" is the same  inquiry  made under RSA 374:33,
         which  authorizes the  Commission to approve  mergers that are "lawful,
         proper and in the public  interest." New England  Electric  System,  DE
         99-035, Order No. 23,308 (1999), slip op. at 16. Thus, proposed mergers
         must  meet  a "no  net  harm"  test  in  order  to be  approved  by the
         Commission. Id. The Commission stated that, in applying the no net harm
         test, it must "assess the benefits and risks of the proposed merger and
         determine  what the  overall  effect on the  public  interest  will be,
         giving the transaction . . . approval if the effect is at worst neutral
         from the public interest perspective." Id. at 16-17.  Accordingly,  the
         Commission's  standard will be met where an applicant for approval of a
         merger

<PAGE>
Joint Petitioners
DG 99-

Page 18

         demonstrates  that customers would be no worse off with the merger than
         without the merger.

         As  discussed  above,  Eastern  and  KeySpan  propose:  (1) to  provide
         customers  with  immediate  gas-cost  savings  through  a  2.2  percent
         burner-tip  price  reduction;  (2) to  develop  with the  Commission  a
         mechanism for identifying and quantifying other cost savings achievable
         only as a result of the merger;  and (3) to be allowed the  opportunity
         to seek, in the future,  recovery of  merger-related  costs required to
         accomplish  the  transaction  only to the  extent  that such  costs are
         demonstrated to be offset by  merger-related  savings.  Because Eastern
         will  have the  opportunity  to  recover  costs  only  through  savings
         demonstrated to result from the merger, the recovery of such costs in a
         future  proceeding  will not cause rates to be any higher for customers
         than what they would have been in the  absence  of the  merger.  At the
         same time,  ENGI's  customers  will receive the benefit of a burner-tip
         price reduction achieved as a result of gas-supply synergies. Thus, the
         proposed  merger  results in net benefits to customers,  and therefore,
         meets and exceeds the Commission's no net harm standard.

         As indicated in the  testimony of Walter J.  Flaherty,  approval of the
         merger in accordance with the terms of Northern  Utilities will provide
         KeySpan  and  Eastern   with  a  reasonable   opportunity   to  recover
         merger-related  costs  only  upon  a  showing  to the  Commission  that
         identified  and  quantified  cost  savings  resulting

         from the merger  warrant  such  recovery.  As further  indicated by Mr.
         Flaherty,  consummation of the merger is expressly  contingent upon the
         Commission's  approval upon terms and conditions  that,  with regard to
         rates and the recovery of costs  associated with the merger  (including
         the acquisition  premium and transaction and integration costs), are no
         less  favorable  than  those set forth by the  Commission  pursuant  to
         Northern Utilities.

Q.       What  impact  will the merger  have on the quality of service to ENGI's
         customers?

A.       Eastern and  KeySpan are  committed  to  maintaining  the high level of
         service quality and reliability provided by ENGI. Moreover, because the
         service  territories  of Colonial Gas and ENGI are  contiguous,  ENGI's
         system can be operated more efficiently when coordinated with Eastern's
         overall  operations.  ENGI  will be able  to rely on the  resources  of
         Boston Gas,  including its information  technology  infrastructure  and
         customer service experience to enhance the quality of service to ENGI's
         customers.  For  instance,  Boston Gas will be able to  replace  ENGI's
         manual  service-dispatch  system with a computer-aided dispatch system,
         which will allow ENGI to be more  responsive to customer  needs,  while
         increasing the productivity of the work-force and reducing labor costs.
         Thus,  the  proposed  merger will not  adversely  affect the quality of
         service experienced by ENGI's customers,  and is likely to result in an
         augmented  level of service  quality because of the resources that will
         be available to the combined companies.

Q.       What impact will the proposed merger have on competition within the gas
         industry?

A.       The acquisition of EnergyNorth will facilitate  greater  competition in
         the gas industry in two significant  respects.  ENGI currently provides
         transportation  service to approximately  100 customers who have chosen
         to take gas service from a competitive  supplier.  In order to increase
         access  to  competitive  alternatives,   ENGI  is  participating  in  a
         collaborative (the "NH  Collaborative")  to consider  unbundling issues
         and is  operating  under  the  belief  that  natural  gas  distribution
         companies  will be  expanding  their  customer  choice  programs in the
         not-too-distant  future. The NH Collaborative is currently  considering
         the adoption of standardized  terms and conditions for service that are
         based on similar terms and  conditions  developed by the  Massachusetts
         Gas  Unbundling  Collaborative,  in which Boston Gas,  Colonial Gas and
         Essex Gas have been full  participants.  Since Boston Gas, Colonial Gas
         and  Essex  Gas  will  be  implementing  the  standardized   terms  and
         conditions  in the  spring  of 2000,  Eastern  is well  positioned  and
         prepared to implement  similar terms and  conditions on the ENGI system
         in a prompt, effective manner and at minimal expense.

         Second,  by  combining  the  resource  portfolios  of ENGI with that of
         Eastern's  gas  distribution  operations,  ENGI  will  be  in a  better
         position to minimize transition costs and to streamline and standardize
         systems for  third-party  gas  marketers in its service  area.  Eastern
         anticipates  using the Broker Management System developed

         by Boston Gas to conduct transactions with marketers in the EnergyNorth
         service territory.  Thus,  competitive suppliers who serve customers in
         both  Massachusetts  and New  Hampshire  will have the benefit of being
         able to  communicate  with Eastern's gas  distribution  operations on a
         standardized  basis,  which  should lower  transaction  costs for those
         marketers.

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
         should  provide the impetus for  economic  development  gains in ENGI'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.

Q.       What  impact will the merger  have on  economic  development  in ENGI's
         service territory?

A.       As stated  earlier,  upon  consummation  of the merger,  delivered  gas
         prices for ENGI's customers will be reduced by 2.2 percent.  Thus, as a
         result of the merger, customers will experience lower, and more stable,
         prices  both in the near and long  term.  The  savings in gas bills for
         customers will benefit the local economy, and therefore,  should have a
         positive   effect  on  economic   development   within  ENGI's

         service  territory.  Given New  Hampshire's  location at the end of the
         interstate  pipeline  network,  utility  consolidation  may be the only
         significant means of reducing energy costs, which will help to maintain
         the competitiveness of New Hampshire's industrial concerns.

Q.       Are there  any other  reasonable  and  cost-effective  ways for ENGI to
         achieve the merger benefits previously discussed without being acquired
         by Eastern and KeySpan?

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.  ENGI'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 and
         resources, together with a gas supply plan coordinated with the KeySpan
         and Eastern gas distribution  operations will permit ENGI to obtain the
         advantages of such economies for its customers.

Q.       Based on your knowledge of ENGI and the area it serves, is the proposed
         merger consistent with the public interest?

A.       Yes, for all of the reasons stated above,  and in  consideration of the
         customer benefits  resulting from gas-supply  synergies,  the merger is
         consistent  with the public  interest,  as required by RSA 369:8,II and
         RSA 374:33.

Q.       Does this conclude your testimony?

A.       Yes, it does.

                           PUBLIC UTILITIES COMMISSION

                        Testimony of Michelle L. Chicoine

I.       INTRODUCTION

Q.       Please state your name and business address.

A.       My name is  Michelle  L.  Chicoine.  My  business  address  is 1260 Elm
         Street, Manchester, New Hampshire 03105.

Q.       By whom are you employed, and in what capacity?

A.       I am  Executive  Vice  President  and a Director of  EnergyNorth,  Inc.
         ("EnergyNorth") and President,  Director and Chief Operating Officer of
         EnergyNorth Natural Gas, Inc. ("ENGI").

Q.       Have you previously testified in proceedings before the Commission?

A.       Yes,  I have  testified  before  the  Commission  on  behalf of ENGI in
         numerous proceedings  involving rate issues,  cost-of-gas  adjustments,
         gas industry unbundling and environmental remediation and cost recovery
         matters.

Q.       What is the purpose of your testimony in this proceeding?

         The purpose of my  testimony is to: (i)  describe  EnergyNorth  and the
         decision to merge EnergyNorth with Eastern Enterprises  ("Eastern") and
         KeySpan Corporation  ("KeySpan");  (ii) describe the benefits available
         as a result  of

         the merger; and (3) endorse the representation by KeySpan,  Eastern and
         EnergyNorth in this case that the rates, terms,  service and operations
         of ENGI  will not be  adversely  affected  by the  merger  and that the
         merger will result in no net harm to customers.

II.      THE DECISION TO MERGE ENERGYNORTH WITH EASTERN

Q.       Please provide a brief description of EnergyNorth.

A.       EnergyNorth is an exempt public utility holding  company  headquartered
         in  Manchester,   New  Hampshire.   EnergyNorth's  principal  operating
         subsidiaries  include ENGI, a local gas distribution  company regulated
         by the New Hampshire  Public Utilities  Commission (the  "Commission"),
         EnergyNorth Propane, Inc., an unregulated retail distributor of propane
         and ENI Mechanicals, Inc., which consists of two mechanical contracting
         companies  engaged in the design,  construction and service of heating,
         ventilating,  air conditioning and process-piping systems.  EnergyNorth
         was  organized in 1982 in accordance  with New  Hampshire  state law in
         order  to  provide  for  the  combination  of  Gas  Service,  Inc.  and
         Manchester  Gas  Company.  In 1985,  EnergyNorth  acquired  the Concord
         Natural Gas Company, which was consolidated with EnergyNorth's existing
         operations to form ENGI.

         ENGI  currently   distributes  natural  gas  to  approximately   72,000
         customers representing more than 75 percent of natural gas customers in
         New Hampshire.  ENGI's service  territory  encompasses  over 900 square
         miles in 28 cities and towns, including Nashua, Manchester and Concord,
         New Hampshire.

Q.       Please explain why EnergyNorth decided to pursue a merger at this time?

A.       Over the past several  years,  EnergyNorth's  Board of  Directors  (the
         "Board") and the management of EnergyNorth  have followed  developments
         in the gas  utility  industry  with a  particular  focus on  changes in
         regulatory  policies.  These changes motivated  EnergyNorth to consider
         carefully  the  impact  of  industry   restructuring   initiatives   in
         formulating  its  future  business  strategy.  With the  unbundling  of
         electric  and gas  services,  the  implementation  of  customer  choice
         programs,  and the evolution of more  competitive  energy  markets,  it
         became increasingly clear to EnergyNorth that its relatively small size
         and limited resources would restrict its future business  opportunities
         and make it difficult to improve  significantly  the  efficiency of its
         operations   on  a  stand-alone   basis.   Although   EnergyNorth   has
         successfully  controlled  ENGI's  costs,  further  cost  reductions  of
         significance  would be available only through the creation of economies
         of scale and/or scope in its operations. Moreover, the Board recognized
         that the synergies and operational  efficiencies that could result from
         a  business  combination  with a  larger  utility  would be  valued  by
         potential  merger  partners,  and  therefore,  would  produce value for
         shareholders in any such transaction. As a result of this analysis, the
         Board, in conjunction  with EnergyNorth  management,  concluded that it
         should further  investigate the benefits for customers and shareholders
         that could potentially result from a business combination with a larger
         utility.

Q.       Why did EnergyNorth  decide to enter into a business  combination  with
         Eastern?

A.       After discussion with several parties,  direct negotiations resulted in
         Eastern  making the proposal that is embodied in the Merger  Agreement,
         as amended. Of particular significance to EnergyNorth was the scale and
         proximity  of  Eastern's  gas  distribution  operations.  The  size  of
         Eastern's gas distribution operations and the fact that Colonial Gas, a
         subsidiary  of  Eastern,  operates  in  a  service  territory  that  is
         contiguous to the  southernmost  portion of ENGI's  service  territory,
         create significant potential for ENGI to achieve operational synergies,
         associated cost reductions and enhanced customer  service.  EnergyNorth
         was  also  aware  that  Eastern  was  in  the  process  of   evaluating
         opportunities for further expansion of its gas distribution  operations
         to reduce the overall costs  associated  with  providing gas service to
         customers, which had the potential to result in further cost reductions
         to ENGI's customers.

         The Board, in conjunction with EnergyNorth management,  determined that
         Eastern's  proposal  offered ENGI's customers and shareholders the best
         possible  overall  benefits  compared to those of all other  interested
         parties.  The Board and ENGI  management  have  since  determined  that
         Eastern's  plan of merger with KeySpan would  encompass  those benefits
         and provide  customers and shareholders  with value over and above that
         available under the arrangement with Eastern.

III.     BENEFITS OF THE MERGER AVAILABLE TO ENGI CUSTOMERS

Q.       What are the benefits of the merger for ENGI's customers, employees and
         shareholders?

A.       The  merger  of  EnergyNorth  with  Eastern  will  provide  significant
         benefits for customers and  shareholders.  Although I believe that ENGI
         is viewed,  both within the industry and within its service  territory,
         as a well-managed  utility  providing quality service to its customers,
         the merger  presents  opportunities  for ENGI to achieve  economies  of
         scale by operating  as a sister  company to Boston Gas,  Colonial  Gas,
         Essex Gas and The  Brooklyn  Union Gas  Company  and  KeySpan  Gas East
         Corporation  d/b/a  The  Brooklyn  Union  Gas  Company  of Long  Island
         (collectively,  the "Brooklyn  Union  Companies").  These  economies of
         scale will produce  benefits for customers  that would not be available
         in the absence of the merger.  For example,  as a result of the merger,
         ENGI's customers will receive a significant reduction in the burner-tip
         price of gas,  as well as  other  benefits  over  time,  as the  merged
         companies are able to gain efficiencies in the provision of services.

         Specifically,   ENGI's  customers  will  be  the  beneficiaries  of  an
         immediate  2.2  percent  reduction  in  their  burner-tip   prices.  As
         mentioned above,  these savings are possible only 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  ENGI  and  the  existing  gas   distribution
         operations of Eastern and KeySpan.

         In  addition,  the merger will provide ENGI with access to resource and
         infrastructure  alternatives that would be prohibitively  expensive for
         ENGI to pursue on a stand-alone  basis. For example,  ENGI will be able
         to take advantage of the significant investment that Boston Gas and the
         Brooklyn Union Companies have made in information  technology,  such as
         the systems  required  to  implement a  comprehensive  customer  choice
         program or to handle customer-service inquiries more efficiently.  ENGI
         will also have increased access to capital  markets,  which will enable
         investments  in  system  infrastructure  at a  lower  cost.  Thus,  the
         proposed merger is in the best interest of ENGI customers.

         Lastly,  the proposed merger will provide  EnergyNorth's  shareholders,
         many of whom are New Hampshire residents and ENGI customers,  with fair
         value for their ownership interest.

Q.       What are some  examples  of  systems  investments  that would have been
         required absent the merger?

A.       Appended  hereto  as  Attachment  MLC-1,  is a list  of the  particular
         systems  that ENGI  planned to invest in,  prior to  reaching a plan of
         merger with Eastern and KeySpan.  ENGI  determined  that  investment in
         such  systems was  required  based,  in part,  on a study  performed by
         Arthur  Andersen  LLP  that  was  subsequently  updated  as  part of an
         internal  information-systems  plan. Based on that analysis, ENGI would
         have  incurred  investment  costs  of over  $4.3  million  to  develop,
         implement and/or modify information  systems and infrastructure  absent
         the
<PAGE>

Page 7

         merger, such as: (1) software to automate the dispatch function; (2) an
         enterprise  level  reporting  and data  warehousing  system to  enhance
         management  reporting;  (3) an upgrade of the telephone system and call
         center;   (4)  an  upgrade  of  the   infrastructure   to   accommodate
         internet/intranet applications; (5) software for payroll/human resource
         functions;  (6) software and  conversion  costs to automate the mapping
         functions;  (7) development  and  implementation  of  disaster-recovery
         capability;  (8) modifications to existing customer  information-system
         and gas-supply  systems to expand the customer choice program;  and (9)
         replacement of the customer-information system.

         For example,  Boston Gas has developed its own Broker Management System
         (the "BMS") in order to  administer  its  customer-choice  program on a
         multi-company basis, i.e., for all of Eastern's operating subsidiaries.
         Because of the merger,  ENGI will have the  opportunity  to utilize the
         BMS developed by Boston Gas rather than incurring the significant  cost
         of procuring and implementing a similar system on its own.

         Similarly,  ENGI's  dispatch and  customer-service  center is currently
         operated on a manual  basis.  ENGI has,  over time,  evaluated the cost
         that would be associated with the  implementation  of a  computer-aided
         dispatch system and has determined that significant investment would be
         required  in order to  obtain,  implement  and  install  such a system.
         However,  as a result of the  merger,  ENGI  will  have  access to this
         technology,  as well as an array of other information systems that will

Page 8

         increase   efficiency  and  enhance   customer   service  with  minimal
         infrastructure  investment  by ENGI.  In fact,  EnergyNorth  views  the
         avoidance  of  technology  investments  to  be  a  significant  benefit
         resulting from the merger.

Q.       Would it be possible for ENGI to achieve  these  savings in the absence
         of the acquisition of EnergyNorth by Eastern?

A.       As I have indicated,  ENGI 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
         price.  However,  there are  limitations on the ability of a company of
         ENGI's  size to  capture  the  high  level  of  savings  that  would be
         available  through a merger with a larger entity.  In this case, Boston
         Gas'  technology  investments can be extended to the operations of ENGI
         and Eastern's gas distribution service territory is contiguous with our
         service territory; therefore, the potential for achieving reductions in
         the cost of the combined operations is substantial. As described in Mr.
         Bodanza's testimony, the acquisition will create economies of scale and
         synergies that present the opportunity  for immediate cost  reductions,
         and  ultimately,  long-term  benefits to customers in the form of lower
         prices.

Q.       What affect would a failure to approve the proposed  merger have on the
         customers of ENGI?

A.       Were the  proposed  merger not to receive  approval,  ENGI's  customers
         would not obtain the immediate 2.2 percent price  reduction  that would
         otherwise  take effect upon approval of the merger.  In addition,  ENGI
         would lose the  opportunity to

<PAGE>

         combine its operations with those of a much larger organization that is
         uniquely  situated to  coordinate  its  operations  with those of ENGI.
         Because  the  service   territories   of  ENGI  and  Colonial  Gas  are
         contiguous, and because Boston Gas is in a position to extend important
         resources such as its advanced  information  systems  technology to our
         operations,  the  proposed  merger with  Eastern  and KeySpan  will not
         adversely affect the rates,  terms,  service or operations of ENGI, and
         instead  will  offer  significant  near  and  long-term   benefits  for
         customers.

Q.       Does this conclude your testimony?

A.       Yes, it does.

                             STATE OF NEW HAMPSHIRE

                           PUBLIC UTILITIES COMMISSION

                         Testimony of William R. Luthern

I.       INTRODUCTION

Q.       Please state your name and business address.

A.       My name is  William  R.  Luthern.  My  business  address  is One Beacon
         Street, Boston, Massachusetts 02109.

Q.       By whom are you employed and in what capacity?

A.       I am Vice  President of Gas Resources  for Boston Gas Company  ("Boston
         Gas").  In my current  position,  I am  responsible  for the  planning,
         acquisition  and marketing of the gas supply  resources for Boston Gas,
         Colonial Gas Company ("Colonial"),  and Essex Gas Company ("Essex"). In
         addition, I am responsible for all state and federal regulatory matters
         relating to gas supply, planning and acquisition.

Q.       Have you previously testified in regulatory proceedings?

A.       Yes,  I  have  testified  in  a  number  of   proceedings   before  the
         Massachusetts   Department  of   Telecommunications   and  Energy  (the
         "Department"),   the  Federal  Energy  Regulatory  Commission  and  the
         Canadian National Energy Board (the "NEB"). Most recently,  I testified
         before the Department in Eastern-Essex

         Acquisition,  D.T.E.  98-27  (1998) and  Eastern-Colonial  Acquisition,
         D.T.E. 98-128 (1999) and before the NEB in Imperial Oil Resources,  Ltd
         and Boston Gas Company, GH-1-99 (1999).

Q.       What is the purpose of your testimony?

A.       The  purpose of my  testimony  is to describe  the  benefits of the gas
         supply synergies resulting from the acquisition of EnergyNorth, Inc. by
         Eastern  Enterprises  ("Eastern"),  the parent  company of Boston  Gas,
         Colonial Gas and Essex Gas, and to explain how these  efficiencies will
         be attained  so as to reduce  future gas supply  costs for  EnergyNorth
         Natural Gas, Inc. ("ENGI") 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  procurement  for  ENGI's
         customers?

A.       Yes, the acquisition  will facilitate the development of more efficient
         gas supply resources for ENGI. Re-optimization of ENGI's portfolio will
         be possible as a result of the  coordination of the gas supply planning
         and acquisition efforts of Boston Gas, Colonial Gas and Essex Gas. Such
         coordination  will create the  opportunity to use more  efficiently the
         resources of these four companies and allow ENGI'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 Colonial Gas and ENGI's system are
         geographically  contiguous, and Boston Gas, Colonial Gas, Essex Gas and
         ENGI

         are connected through the Tennessee Gas Pipeline Company ("Tennessee").
         Moreover,  as addressed  in the  testimony  of Craig G.  Matthews,  the
         potential to achieve additional  synergies may be increased as a result
         of Eastern's planned merger with KeySpan Corporation ("KeySpan").

Q.       Please provide a brief description of ENGI's current supply portfolio.

A.       ENGI  receives all of its  pipeline  deliveries  through the  Tennessee
         pipeline.  A summary of the portfolio of resources held by ENGI to meet
         its requirements is set forth in Attachment  WRL-1.  ENGI currently has
         long-haul transportation contracts with Tennessee for 21,596 dekatherms
         ("Dth")  per  day.  In   addition,   ENGI  holds   several   short-haul
         transportation  contracts  totaling  28,115  Dth  per  day  to  deliver
         underground storage volumes. ENGI purchases its commodity  requirements
         under several  domestic  arrangements  to meets its sendout and storage
         refill  requirements,  as well as under  contracts  with three Canadian
         suppliers. Such Canadian volumes are delivered from the Canadian border
         under domestic transportation  agreements with Tennessee,  the Iroquois
         Gas Transmission  System and Portland Natural Gas Transmission  System,
         totaling 8,122 Dth per day.

         EnergyNorth   operates  several   liquefied  natural  gas  ("LNG")  and
         propane-air  facilities with a total storage capacity of 126,252 Dth to
         meet  peak-shaving  requirements on a system-wide  basis. To supplement
         its own  peak-shaving

<PAGE>
Joint Petitioners
DG 99-

Page 4

         capacity,   ENGI  has  contracts   with   Distrigas  of   Massachusetts
         Corporation  ("DOMAC") and El Paso Energy  Marketing  Company,  for the
         provision of peaking supplies totaling 23,000 Dth per day.

Q.       Are you familiar with the manner in which ENGI's upstream  pipeline and
         storage volumes are delivered to ENGI's city gates?

A.       Yes.  Boston  Gas,  Colonial  Gas and Essex Gas  subscribe  to  similar
         services on the Tennessee  pipeline as ENGI, and  therefore,  transport
         long-haul domestic  supplies,  short-haul storage supplies and Canadian
         supplies under the same basic rate schedules as ENGI.

Q.       On what basis did you  determine  that it was  possible  to capture gas
         supply synergies for the two systems?

A.       As a first  step,  I  reviewed  the  gas  supply  portfolio  of ENGI to
         determine the maximum daily quantity, annual delivery limitations,  and
         termination dates of each contract.  I also reviewed ENGI'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  ENGI's  gas  supply  portfolio  with  that of  Boston  Gas,
         Colonial Gas and Essex Gas. In order to determine which resources could
         be reduced or eliminated  through the coordination of the ENGI resource
         portfolio  with that of Boston  Gas,  Colonial  Gas and Essex  Gas,  we
         analyzed the use of Boston Gas,  Colonial Gas and Essex Gas  resources,
         with and without ENGI's operations.  Specifically,  a dispatch analysis
         was performed using Boston Gas,

<PAGE>
Joint Petitioners
DG 99-
Witness:  Luthern
December 3, 1999
Page 5

         Colonial Gas and Essex Gas resources to meet their system requirements,
         in isolation,  and a dispatch analysis of ENGI's resources to meet ENGI
         system  requirements.  Finally,  we performed a dispatch analysis using
         all  resources  to meet the  combined  systems'  aggregate  load.  This
         analysis  allowed us to determine  the most  efficient  resource mix to
         meet total combined load requirements. This analysis also allowed us to
         identify  whether  incremental  levels of Boston Gas,  Colonial Gas and
         Essex  Gas  resources  could or would be  utilized  to  substitute  for
         certain  resources in the ENGI portfolio,  and whether ENGI's resources
         could displace certain  elements in Boston Gas,  Colonial Gas and Essex
         Gas portfolios with the savings credited back to ENGI's customers.

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  ENGI's  resource   portfolio  and  gas
         requirements,  several  cost-saving  measures are available,  which are
         illustrated  in  Attachment  WRL-2.  For  example,   implementation  of
         combined  asset-management  initiatives in conjunction with Boston Gas,
         Colonial  Gas and Essex Gas has the  potential  to produce  annual cost
         savings to ENGI's customers of approximately  $800,000. I also estimate
         that  approximately  $850,000 in savings  would be  available  annually
         through the combined dispatch of the gas supply portfolios, which would
         allow  ENGI to avoid  certain  pipeline  peaking  services,  as well as
         approximately
<PAGE>

Joint Petitioners
DG 99-

December 3, 1999
Page 6

         $200,000 in annual costs  associated with the  renegotiation of various
         underground storage arrangements.

         As indicated in Attachment  WRL-2, I estimate that  additional  savings
         will be  available  as a result of reduced gas  commodity  expenses and
         further  restructuring of upstream pipeline  services.  I estimate that
         these  additional  savings would initially  amount to roughly  $162,500
         annually.  Significantly,  the initial  savings that we have identified
         would not be  available  in the  absence  of the merger  because  these
         savings stem from the ability to eliminate resources that are redundant
         only as a result of the combined  management  of the combined  resource
         portfolio,  and from the ability to roll ENGI's resource portfolio into
         the  asset-management  arrangement  that Boston Gas,  Colonial  Gas and
         Essex Gas have established with El Paso.

Q.       Will the effort to attain gas-supply cost reductions  negatively affect
         the overall reliability of ENGI's gas service?

A.       Any  gas-supply  synergies  that we achieve as a result of the proposed
         merger  of  Eastern  and  EnergyNorth  will  be  produced  through  the
         coordination and integration of ENGI's resource  portfolio with that of
         Boston  Gas,  Colonial  Gas and  Essex  Gas,  and not  simply  from the
         reduction or  elimination  of  resources  necessary to meet ENGI system
         requirements.  In assembling a resource portfolio, a local distribution
         company  may  rely on  resources  that  are  necessary  to meet  system
         requirements  on a stand-alone  basis,  but that may be redundant  with
         similar
<PAGE>

Joint Petitioners

Page 7

         resources  on other  distribution  systems.  By  coordinating  the ENGI
         portfolio  with that of Eastern's gas  distribution  operations,  these
         resources may be eliminated without jeopardizing the reliability of the
         resource portfolio.  In fact, as a result of the merger, ENGI will have
         access to the broader set of  resources  that  constitute  the combined
         portfolios of Boston Gas,  Colonial Gas and Essex Gas. At this time, we
         have not  identified  any other  synergies  than those  illustrated  in
         Attachment WRL-2 that could be achieved  without  affecting our ability
         to meet ENGI's system requirements.  However, it is our experience with
         the Colonial Gas and Essex Gas mergers  that,  as  integration  efforts
         proceed  and   experience  is  gained  with  the  combined   portfolio,
         additional gas-supply synergies may be identified and achieved. We also
         anticipate that additional cost savings may be available as a result of
         coordination with the gas distribution operations of KeySpan.

Q.       What are the  total  gas  supply  savings  that you  estimate  would be
         attainable  and how do  those  savings  compare  to  ENGI's  burner-tip
         prices?


A.       I estimate  that gas cost  savings  of $2.0  million  annually  will be
         achieved by the 2000/01  heating  season,  which will  escalate to $2.3
         million  annually by the 2003/04 heating  season.  As calculated in the
         testimony of Mr. Bodanza, the $2.0 million in annual savings represents
         a 2.2 percent reduction in the burner-tip prices of ENGI's customers.

Q.       How will ENGI  customers  be assured that they will receive the benefit
         of  gas-cost  savings  now,  and in the future,  should the  Commission
         approve the proposed merger?

A.       The gas-supply  synergies  achieved as a result of the  coordination of
         the resource  portfolios of ENGI and Boston Gas, Colonial Gas and Essex
         Gas will be attained through a series of cost-saving  measures.  As set
         forth in Attachment  WRL-2,  we have identified the type of cost-saving
         measures  that we believe  can be  achieved  in the near  future and we
         anticipate  that  additional  gas-cost  savings may be achievable  over
         time. The costs associated with gas-supply resources are recovered from
         customers  through  the Cost of Gas  ("COG")  factor.  Because  the COG
         factor  functions as a  pass-through  mechanism,  any gas-cost  savings
         achieved  now, or in the future,  would be passed  through to customers
         through the normal operation of the COG factor.  In our experience with
         the  Colonial Gas and Essex Gas mergers,  customers  have  received the
         benefit of substantial gas-cost savings in excess of those projected as
         part of the merger  filing,  and are currently  enjoying the benefit of
         those reduced costs through the COG factor.

Q.       Will coordination of ENGI's resource portfolio with that of Boston Gas,
         Colonial Gas and Essex Gas have any effect on competition?

A.       We  believe  that the  consolidation  of the gas  supply  and  dispatch
         operations   will  actually   facilitate   the  move  to  an  unbundled
         environment  because of two factors.  First,  the  coordination  of the
         Boston  Gas,  Colonial  Gas,  Essex  Gas and ENGI  resource  portfolios
         provides  a  unique  opportunity  to  consolidate  and  reoptimize  the
         portfolios,  which will create a more  flexible  and less costly mix of
         resources for assignment to migrating  customers.  Second, as discussed
         by Mr.  Bodanza,  ENGI

<PAGE>

Page 9

         has not yet developed its information-systems technology to accommodate
         system-wide service by third-party  competitive suppliers.  As a result
         of the  merger,  ENGI  will  be  able  to  minimize  the  cost  of this
         undertaking  by  taking  advantage  of  the  Broker  Management  System
         developed by Boston Gas. More importantly,  competitive  suppliers will
         be  able  to  transact  business  using   standardized   communications
         protocols  across all four service  territories,  which should minimize
         transaction costs for competitive suppliers. In that regard, the merger
         will facilitate ENGI's  transition to an unbundled  environment for the
         benefit of those customers and competitive suppliers who are interested
         in serving customers on ENGI's system.

Q.       Does this complete your testimony?

A.       Yes, it does.

                           PUBLIC UTILITIES COMMISSION

                         Testimony of Craig G. Matthews

I.       INTRODUCTION

Q.       Please state your name and business address.

A.       My name is Craig G.  Matthews.  My  business  address is One  MetroTech
         Center, Brooklyn, New York, 11209.

Q.       By whom are you employed, and in what capacity?

A.       I am  President  and Chief  Operating  Officer of  KeySpan  Corporation
         ("KeySpan") and its largest  operating  subsidiary,  The Brooklyn Union
         Gas Company ("Brooklyn Union"). I am also a Director of Brooklyn Union.

Q.       Have you previously testified before any regulatory commission?

A.       Yes.  I have  testified  before  the  New  York  State  Public  Service
         Commission  in  several  proceedings  involving  a  number  of  issues,
         including  rate  and  accounting  issues  and  corporate   organization
         matters.

Q.       What is the purpose of your testimony?

A.       The  purpose of my  testimony  is to  describe  various  aspects of the
         proposed acquisition by KeySpan of Eastern Enterprises ("Eastern"), and

         EnergyNorth  Natural Gas,  Inc.  ("ENGI").  Specifically,  my testimony
         provides:  (i) a  background  description  of KeySpan;  (ii)  KeySpan's
         rationale  for  the   acquisition   of  Eastern,   and   indirectly  of
         EnergyNorth;  (iii) the impact of KeySpan's planned merger with Eastern
         on the  commitments  advanced by Eastern in this proceeding with regard
         to the  operations  of  ENGI;  and  (iv)  a  summary  of  the  required
         regulatory  approvals  necessary  to effect the  merger of KeySpan  and
         Eastern.

II.      BACKGROUND OF KEYSPAN CORPORATION

Q.       Please describe the background and operations of KeySpan.

A.       KeySpan is a New York corporation  headquartered in Brooklyn, New York.
         KeySpan is a holding  company that owns 100 percent of the common stock
         of two local  distribution  companies  serving  a total of 1.6  million
         natural gas customers in New York City (Brooklyn Union) and Long Island
         (through  KeySpan Gas East  Corporation  d/b/a  Brooklyn  Union of Long
         Island).  KeySpan  was  formed  in 1998,  when the  parent  company  of
         Brooklyn  Union  combined with the natural gas local  distribution  and
         electric  generating  businesses  that had been divested by Long Island
         Lighting Company.

         KeySpan is a multi-faceted  energy company primarily focused on serving
         the growing  downstream  markets in the Northeast.  KeySpan's  business
         enterprises   consist  of  five  business  units,   including  its  gas
         distribution   operations.   In addition

<PAGE>
Joint Petitioners
DG 99-
Witness:  Matthews

Page 3

         to the gas distribution  operations,  KeySpan's  business units include
         electric  services,   energy-related   services,  gas  exploration  and
         production and energy-related investments.

         Specifically,  KeySpan's  electric  services  business  units  own  and
         operate  more than  6,168  megawatts  of  electric  generation  on Long
         Island, New York and in New York City. In addition, KeySpan manages the
         transmission  and  distribution of electricity to more than one million
         electric  customers  on Long  Island,  under a  contract  with the Long
         Island Power Authority.

         KeySpan's energy-related services business unit includes KeySpan Energy
         Services, an unregulated retail marketing affiliate that buys and sells
         gas and  electricity  and  provides  related  services to  residential,
         commercial and industrial customers  throughout the Northeast.  KeySpan
         Energy   Solutions   provides   service  and  maintenance  for  heating
         equipment,  water heaters, central air conditioners and gas appliances.
         In addition,  KeySpan  Energy  Management  designs and operates  energy
         systems  of   large-scale   residential,   commercial   and  industrial
         facilities and provides  services to customers ranging from engineering
         to  operations.  Most  of the  contracts  serviced  by  KeySpan  Energy
         Management  include long-term  operations,  maintenance,  financing and
         fuel supply arrangements.

         KeySpan currently owns 64 percent of The Houston Exploration Company, a
         public company (NYSE), which is engaged in the exploration, development
         and  acquisition  of natural  gas and oil  properties.  The company has
         offshore  properties  in  the  Gulf  of  Mexico,  as  well  as  onshore
         properties in Texas and West Virginia.  The remaining 36 percent of The
         Houston Exploration Company is publicly held.

         KeySpan's  energy-related  investments  business  unit is involved in a
         wide  range  of   unregulated   project   development   efforts,   both
         domestically and  internationally.  KeySpan's  investments include a 20
         percent  share in the  Iroquois  Gas  Transmission  System and numerous
         other  investments  related  primarily to gas pipeline and distribution
         assets in the United  Kingdom and  midstream gas  processing  assets in
         Canada.

         KeySpan  has  stated   publicly  that  it  is  reviewing  its  non-core
         businesses,   such  as  The   Houston   Exploration   Company  and  its
         international  investments  in order to maintain a strong  focus on its
         core downstream businesses.

Q.       Please provide an overview of KeySpan's planned merger with Eastern and
         EnergyNorth.

A.       On November 4, 1999,  KeySpan,  Eastern and ACJ Acquisition LLC ("ACJ")
         entered  into an  Agreement  and Plan of Merger  (the  "Eastern  Merger
         Agreement") under which KeySpan will acquire all of the common stock of
         Eastern for $64.00 per share in cash.  As  described  below,  KeySpan's
         merger with  Eastern is

<PAGE>
Joint Petitioners
DG 99-
Witness:  Matthews
December 3, 1999
Page 5

         conditioned  upon  the  approval  of  Eastern's  shareholders  and  the
         approval of the  Securities  and  Exchange  Commission  ("SEC") of: (1)
         KeySpan's acquisition of the common stock of Eastern; and (2) KeySpan's
         application  to become a registered  holding  company  under the Public
         Utilities  Holding  Company Act of 1935 ("PUHCA").  KeySpan's  indirect
         acquisition  of  EnergyNorth  and ENGI requires the approval of the New
         Hampshire Public Utilities Commission (the "Commission"), but KeySpan's
         acquisition of Eastern is not conditioned upon that approval.

         As set forth in the  testimony of Walter J.  Flaherty,  upon receipt of
         the necessary  regulatory  approvals,  EE Acquisition  Company ("Merger
         Sub"),  a wholly owned  subsidiary of Eastern,  will be merged with and
         into  EnergyNorth  in  accordance  with  the  laws of the  State of New
         Hampshire.  EnergyNorth  will be the  surviving  corporation  and  will
         continue to operate as "EnergyNorth,  Inc." under the laws of the State
         of New  Hampshire.  In order to  accomplish  the merger,  each share of
         EnergyNorth   common  stock  will  be  extinguished  and  automatically
         converted  into the right to receive  $61.13 in cash.  This  conversion
         will be a taxable event to the  shareholders of  EnergyNorth.  Upon the
         completion of the merger transaction,  EnergyNorth will become a wholly
         owned subsidiary of Eastern.

         Simultaneously,  ACJ, a subsidiary of KeySpan,  will be merged with and
         into Eastern in a merger structure referred to as a "reverse triangular
         merger" for tax

         and reorganization  purposes.  In order to accomplish the merger,  each
         share of Eastern common stock will be  extinguished  and  automatically
         converted  into the  right to  receive  $64.00  in cash.  As a  result,
         Eastern, and indirectly, EnergyNorth and ENGI, will become subsidiaries
         of KeySpan.

III.     THE RATIONALE FOR THE ACQUISITION OF EASTERN

Q.       Please describe  KeySpan's business strategy with regard to mergers and
         acquisitions?

A.       As the owner of two natural gas local distribution  companies,  KeySpan
         has a long history and considerable  experience in operating businesses
         that are very similar to the gas distribution businesses of Eastern and
         EnergyNorth.  KeySpan's gas  companies  have  aggressively  pursued the
         expansion of their gas service and have  recently  jointly  proposed to
         the  New  York  State  Public  Service  Commission  an  innovative  and
         aggressive approach for accelerating customer  participation in the gas
         commodity  service  marketplace.  Both of these  efforts  are  aimed at
         increasing customer choice for energy services.  KeySpan perceives that
         similar  efforts in the service  territories of Eastern and EnergyNorth
         would  contribute  to the growth in the use of gas on those systems and
         encourage customer choice.  KeySpan believes that its service territory
         and the  service  territories  of Eastern and  EnergyNorth  are similar
         markets and are subject to similar regulatory climates that are focused
         on steering  the industry  through a  transformation  to increased  gas
         commodity service competition and increased customer choice. With this,
         KeySpan  anticipates

<PAGE>
Joint Petitioners
DG 99-
Witness:  Matthews
December 3, 1999
Page 7

         opportunities   for  synergies  while  continuing  the  high  level  of
         commitment,  in which KeySpan takes great pride, to system reliability,
         customer  service,   community  involvement  and  development,   and  a
         productive diverse work force.

         Q. What specific  factors played a role in KeySpan's  decision to enter
         into  a  business  combination  with  Eastern,  and  indirectly,   with
         EnergyNorth and ENGI?

A.       We have identified  potential  synergies from KeySpan's  acquisition of
         Eastern that may arise from increased  efficiencies in the combined gas
         supply  function and the  integration  of certain other  administrative
         functions.  Although we have not yet specifically identified additional
         synergies that would arise from KeySpan's acquisition of Eastern, it is
         our judgment that synergies may be achieved in those same areas.

         KeySpan's  acquisition  of Eastern may provide other  benefits as well.
         KeySpan's  commitment to economic  development  in its  franchised  gas
         service territories is longstanding and widely acknowledged. A visit to
         downtown  Brooklyn  demonstrates  the  economic  renaissance  that  has
         occurred over the last decade,  stimulated in large part by the efforts
         of Brooklyn  Union.  Brooklyn  Union of Long Island also has been quite
         active in promoting  economic  development in its service territory and
         has increased that involvement since its merger into KeySpan.  Brooklyn
         Union has special-area  development rates in New York City and

<PAGE>
Joint Petitioners
DG 99-
Witness:  Matthews
December 3, 1999
Page 8

         Brooklyn Union of Long Island recently began to offer  area-development
         rates as well.

         KeySpan, in addition to its cooperative work with local municipalities,
         devotes  considerable  resources of employee  volunteers and charitable
         donations to day-to-day involvement with local not-for-profit  agencies
         that are key to developing  the social and economic  infrastructure  of
         the communities within its service territories. It has found that these
         efforts  redound to the benefit of customers and  shareholders  through
         community  economic  growth  and  will  extend  this  approach  to  its
         involvement in the Massachusetts and New Hampshire  communities  served
         by Eastern and EnergyNorth.

IV.      IMPACT OF THE KEYSPAN/EASTERN MERGER ON ENERGYNORTH TRANSACTION

Q.       Is the KeySpan  merger with Eastern  contingent  upon the  Commission's
         approval of the  indirect  acquisition  by KeySpan of  EnergyNorth  and
         ENGI?

A.       No.  KeySpan is  seeking  the  Commission's  approval  of its  indirect
         acquisition of ENGI. However,  KeySpan's  acquisition of Eastern is not
         dependent on  Eastern's  acquisition  of  EnergyNorth.  Therefore,  the
         termination of Eastern's  acquisition of EnergyNorth,  whether based on
         Commission rejection of the proposed merger or other reasons,  will not
         affect the consummation of the KeySpan acquisition of Eastern.

Q.       Will  KeySpan's  indirect  acquisition  of ENGI  affect  the  corporate
         structure of ENGI or the Commission's jurisdiction over its operations?

A.       The structure of ENGI's  operations  will not change as a result of the
         merger and the Commission's  jurisdiction with respect to the company's
         operations will remain  unaltered.  ENGI, will continue to operate as a
         New Hampshire  corporation  subject to the Commission's full regulatory
         authority.  Thus, the Commission's jurisdiction over rates, service and
         other matters of ENGI, will not be affected by the merger.

         Following  the  merger,   EnergyNorth's  headquarters  will  remain  in
         Manchester,  New Hampshire and the terms of all  collective  bargaining
         agreements  will  be  fulfilled.  KeySpan  and  Eastern  will  maintain
         EnergyNorth's  commitment of charitable  contributions  to  communities
         served  by  the  company  and  a  level  of  involvement  in  community
         activities  as carried on in recent  years.  In  addition,  KeySpan and
         Eastern will establish a local  advisory  board  consisting of not less
         than five members, to be chaired by Robert R. Giordano, for a period of
         at least three years  following the merger.  Membership on the advisory
         board will be offered to all current  members of the Board of Directors
         of EnergyNorth  who are residents of the State of New  Hampshire.  This
         will provide  Eastern and KeySpan with access to the advice and counsel
         of  EnergyNorth's  directors  for at least  three years  following  the
         merger and provide  important  continuity  by retaining the

         services  of   individuals   having  a   longstanding   commitment   to
         EnergyNorth, ENGI and the communities they serve.

V.       REGULATORY APPROVALS REQUIRED

Q.       What regulatory approvals are required for completion of the merger?
A.       As discussed above,  KeySpan's indirect  acquisition of EnergyNorth and
         ENGI requires the Commission's approval.  Pursuant to the provisions of
         PUHCA,  as well as the terms of the Eastern Merger  Agreement,  the SEC
         must approve  KeySpan's  acquisition of the common stock of Eastern and
         KeySpan's  application  to  become a  registered  holding  company.  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 United States  Department of Justice may review any
         antitrust issues that are raised by the merger.

Q.       Does this conclude your testimony?

A.       Yes, it does.

The Board of Directors
KeySpan Corporation
One Metrotech Center

Brooklyn, New York 11201-3850


Ladies and Gentlemen:

You have requested our opinion, as of October 27, 1999, as to the fairness, from
a  financial  point of view,  to  KeySpan  Corporation  (the  "Company")  of the
consideration proposed to be paid by the Company in connection with the proposed
merger (the "Merger") of the Company with Eastern  Enterprises  (the  "Seller").
Pursuant to the Agreement and Plan of Merger,  dated as of November 4, 1999 (the
"Agreement"),  between  the  Company  and the  Seller,  the Seller will become a
wholly-owned  subsidiary of the Company, and the Company will pay for each share
of Common Stock, par value $1.00 per share, of the Seller consideration equal to
$64.00 per share in cash.

In arriving at our opinion,  we have  reviewed (i) the  Agreement;  (ii) certain
publicly  available  information  concerning  the  business of the Seller and of
certain other companies engaged in businesses comparable to those of the Seller,
and the reported market prices for certain other  companies'  securities  deemed
comparable;  (iii) publicly  available terms of certain  transactions  involving
companies  comparable  to the Seller  and the  consideration  received  for such
companies;  (iv) historical market prices of the common stock of the Seller; (v)
the audited  financial  statements  of the Company and the Seller for the fiscal
year ended  December 31, 1998,  and the  unaudited  financial  statements of the
Company and the Seller for the period ended  September  30,  1999;  (vi) certain
internal financial analyses and forecasts prepared by the Company and the Seller
and  their  respective  managements;  and  (vii)  the  terms of  other  business
combinations that we deemed relevant.

In addition,  we have held discussions with certain members of the management of
the Company and the Seller with  respect to certain  aspects of the Merger,  the
past  and  current  business  operations  of the  Company  and the  Seller,  the
financial  condition and future  prospects and operations of the Company and the
Seller,  the  effects  of the  Merger  on the  financial  condition  and  future
prospects of the Company, the expected combination benefits  ("Synergies") to be
achieved through the merger, the expected regulatory treatment of such Synergies
and certain other matters we believed  necessary or  appropriate to our inquiry.
We have reviewed such other  financial  studies and analyses and considered such
other information as we deemed appropriate for the purposes of this opinion.

In giving our  opinion,  we have relied upon and  assumed,  without  independent
verification, the accuracy and completeness of all information that was publicly
available  or was  discussed

<PAGE>

                                      -2-

with us or furnished  to us by the Company and the Seller or otherwise  reviewed
by us, and we have not assumed any responsibility or liability therefor. We have
not conducted any valuation or appraisal of any assets or liabilities,  nor have
any such  valuations or appraisals  been provided to us. In relying on financial
analyses  and  forecasts  provided  to us, we have  assumed  that they have been
reasonably prepared based on assumptions reflecting the best currently available
estimates and  judgments by the  respective  managements  of the Company and the
Seller as to the expected  future results of operations and financial  condition
of the Company and the Seller to which such  analyses or  forecasts  relate.  We
have also assumed that the other transactions contemplated by the Agreement will
be  consummated  as described in the  Agreement.  We have relied as to all legal
matters relevant to rendering our opinion upon the advice of counsel.

Our opinion is based on economic,  market and other  conditions as in effect on,
and the  information  made  available to us as of October 27, 1999. It should be
understood  that this opinion does not reflect  subsequent  developments  and/or
changes in economic, market and other conditions subsequent to October 27, 1999.
We do not have any obligation to update, revise, or reaffirm this opinion.

We have acted as  financial  advisor to the Company with respect to the proposed
Merger and will  receive a fee from the Company for our  services.  We will also
receive an additional fee if the proposed Merger is consummated. In the ordinary
course of their  businesses,  J.P. Morgan Securities Inc. and its affiliates may
actively  trade the debt and equity  securities of the Company or the Seller for
their own account or for the accounts of customers and, accordingly, they may at
any time hold long or short positions in such securities.

On the basis of and  subject to the  foregoing,  it is our opinion as of October
27, 1999 that the consideration to be paid by the Company in the proposed Merger
is fair, from a financial point of view, to the Company.

This letter is provided to the Board of Directors  of the Company in  connection
with and for the purposes of its evaluation of the Merger.  This opinion may not
be disclosed,  referred to, or  communicated  (in whole or in part) to any third
party for any purpose  whatsoever  except with our prior written consent in each
instance.  This opinion may be  reproduced  in full in any proxy or  information
statement  mailed  to  stockholders  of the  Company  but may not  otherwise  be
disclosed  publicly in any manner without our prior written approval and must be
treated as confidential.

Very truly yours,

J.P. MORGAN SECURITIES INC.

             Analysis of the Economic Impact of a Divestiture of the
                 Electric Operations of KeySpan Generation, LLC

I.       Executive Summary

KeySpan Corporation, d/b/a KeySpan Energy ("KeySpan") has prepared this analysis
in order to quantify  the economic  impact on  shareholders  and  customers of a
spin-off, into a separate,  stand-alone entity, of KeySpan's electric generation
business  which  is  conducted  through  its  wholly-owned  subsidiary,  KeySpan
Generation,  LLC ("KeySpan  Generation",  or the "Company").  KeySpan Generation
owns and  operates an aggregate  of 53 steam and  internal  combustion  electric
generating  units  located  throughout  Long Island  having a total  capacity of
approximately  4032 megawatts.  The Company provides electric  capacity,  energy
conversion,  and ancillary services to the Long Island Power Authority ("LIPA"),
the corporate  municipal  instrumentality  providing  retail electric service to
Long Island,  pursuant to a Power Supply Agreement dated as of June 26, 1997 and
effective May 28, 1998 (the "Power  Supply  Agreement" or "PSA") and approved by
the Federal  Energy  Regulatory  Commission  ("FERC").1  This study analyzes and
shows the  additional  costs  and  inefficiencies  the  Company  would  incur if
operated as an  electric  generation  business  independent  from other  KeySpan
businesses.  This  assessment  is based on the current  operating  structure  of
KeySpan's   holding  company  system  as  well  as  knowledge  of  the  staffing
requirements of other electric  utilities based on benchmarking data supplied by
Mercer Management Consulting,  Inc. ("Mercer").

____________________

1  On May 28, 1998, LIPA purchased the electric  transmission  and  distribution
   system of the Long Island  Lighting  Company  ("LILCO")  for the  purposes of
   reducing  retail  electric rates by acquiring all of the  outstanding  common
   stock of LILCO for $2.5 billion in cash and assuming  certain  liabilities of
   the company including  approximately $3.4 billion in debt.  Immediately prior
   to the acquisition,  all of LILCO's assets employed in the conduct of its gas
   distribution  and non-nuclear  generation  businesses,

                                       1

The effects on shareholders  were  calculated  based on the increased costs from
divestiture  assuming no  regulatory  nor contract  rate relief to recover these
additional costs. The effects on customers were calculated  assuming recovery of
additional costs from LIPA under a modified PSA. This study attempts to quantify
many of the  direct  increases  in the cost of  labor,  facilities,  information
technology resources,  and financing that would be experienced in the event of a
spin-off  of the  Company.  In  addition to such  direct  costs,  the  Company's
generation  business obtains a number of indirect  benefits as part of KeySpan's
holding  company system which are difficult to quantify and would be lost in the
event of divestiture.  These indirect lost economies, such as the procurement of
equipment,  are  discussed  in the  body of this  report.  Furthermore,  KeySpan
Generation's  contractual obligations to LIPA place significant  restrictions on
the  disposition  and operation of the  Company's  assets and  resources.  These
restrictions  would complicate a divestiture and are discussed in more detail in
this report.

Shareholder Perspective

Our  analysis  indicates  that  a  divestiture  of  KeySpan  Generation  into  a
stand-alone  company would result in increased  operating expenses primarily due
to higher labor and overhead costs for the stand-alone company. The total annual
impact  of lost  economies  is  estimated  to be  approximately  $17.4  million.
Incremental staffing  requirements would total 84 full-time management and staff
positions.  The estimated total  incremental labor costs are expected to be $9.1
million  annually.  The  other  $8.3  million  in  incremental  costs are due to
insurance and external auditing costs,  spin-off transaction costs, and costs

to replace  and/or  duplicate  information  systems  hardware and software.  The
estimated effects on the Company are shown in Table 1 below.

In Table 1, lost economies  represent the  additional  costs,  excluding  income
taxes,  for the Company,  assuming  operation  as a  stand-alone  entity.  Total
Revenues  reflect the  electric  operating  revenues  for the Company for the 12
months  ended  December 31,  1999.  Total  Expenses  include all  operation  and
maintenance  (O&M) expenses,  depreciation,  taxes other than income taxes,  and
interest  expense.2  Gross Income is the  difference  between Total Revenues and
Total Expenses  excluding income taxes. Net Income is equal to Gross Income less
income taxes. Rate Base refers to the book capitalization at December 31, 1999.

Customer Perspective

Assuming the Company was allowed to recover the increased  costs of  stand-alone
operations including related income taxes pursuant to the PSA, and the increased
costs were passed on by LIPA to its ratepayers, the projected effect on the over
one million retail electric customers of Long Island is as follows:

Conclusion

The  economies  that KeySpan  Generation  realizes from  KeySpan's  consolidated
administration  and  management  of its  electric  and  gas  operations  provide
significant benefits to customers and shareholders.  The centralized  management
provided  by KeySpan  allows the  Company to realize  economies  of scale in the
procurement of equipment,  various technical and  administrative  services,  and
financing.  Spinning the business off into a  stand-alone  company  would likely
result in substantial cost increases and significant  earnings  decreases absent
regulatory and contract rate relief. Without a rate adjustment,  which under the
terms of the PSA may not occur prior to June 1, 2003,  without LIPA's and FERC's
approval,  such increased  costs would be borne by the  shareholders  of KeySpan
Generation. As a result, the spin-off would have significant negative impacts on
shareholders.


                                       4

<PAGE>

The increased  costs from  divestiture,  whether or not they are recoverable via
the PSA,  are  unlikely to result in an  increased  level and quality of service
above that currently provided to LIPA. Nevertheless, the estimated rate increase
required  to  recover  lost  economies  is 5.8%.  This  increase  would make the
stand-alone  company less  competitive at a time when  competition in the energy
industry is rapidly increasing due to state and federal restructuring efforts in
both the electric and gas industries.

Based on the foregoing,  KeySpan Generation's operations as a stand-alone entity
would adversely  affect both KeySpan's  shareholders and LIPA's one million plus
retail electric customers. Therefore, it is in the best interest of shareholders
and  ratepayers to permit  KeySpan to retain  KeySpan  Generation.  Furthermore,
since LIPA now owns the electric  transmission and  distribution  system on Long
Island and entered into various  management  and power  supply  agreements  with
KeySpan  subsidiaries for the purpose of reducing electric rates on Long Island,
it is unlikely that LIPA would approve of a  divestiture  of KeySpan  Generation
that could result in higher rates for its  customers.  In fact,  the  generation
rates  currently  being  charged by the  Company  under the PSA  include  annual
credits  totaling  $173  million  over a ten year period to reflect  anticipated
costs savings that were  forecasted to result from the merger and  consolidation
of LILCO's common and administrative assets and functions with those of KeySpan.

II.      Analytical Approach and Study Assumptions

A.       Overview

To estimate the increased costs due to a divestiture of KeySpan  Generation,  an
organizational assessment of the Company was performed as it exists today; first
on its own, and then as part of the larger KeySpan organization. To assess where
additional  costs would be incurred as a result of a divestiture,  the areas and
functions  which are  currently  being  provided  fully or  partially by various
KeySpan service company  affiliates  (the "Service  Companies"),  were examined.
Given that the Company would be operating on a stand-alone  basis and would need
to   either   perform   these   functions   on  its  own  or   outsource   these
responsibilities,  an estimate  was made of the  additional  costs that would be
incurred as a result of  transferring  the functions  provided by the parent and
the Service Companies to the stand-alone entity.

In  performing  this  assessment,   each  area,  department,   or  function  was
incorporated  into the  stand-alone  Company to ensure that the current level of
service being  provided to LIPA is  maintained.  The  increased  costs were then
estimated by comparing the incremental costs of stand-alone  operations with the
allocated charges from the parent and the Service  Companies.  While divestiture
would likely  impact the costs of many  departments  and  business  units within
KeySpan Generation, the study does not assume additional cost increases in areas
outside of the functional and administrative  departments provided by the parent
and the Service  Companies.  The study does,  however,  attempt to quantify  the
increased   shareholder-related  costs  associated  with  independent  corporate
existence.


                                       6

<PAGE>


The analysis of lost economies  presented herein is based on the  organizational
structure  of KeySpan  that  existed at  year-end  1999.  Under this  structure,
executive management, and common, administrative and general functions have been
consolidated and streamlined to achieve  economies of scale, and are provided to
KeySpan's  regulated and non-regulated  businesses by the parent and the Service
Companies.  Functions  performed  under this  consolidated  arrangement  include
executive  management,  human  resources,  information  systems and  technology,
accounting,   payroll,  financial  reporting,  customer  relations,  public  and
governmental  relations,  facilities  and  vehicle  management,   financial  and
strategic  planning,  treasury  services,  insurance and risk management,  legal
services, and investor relations.

In  evaluating  the  impact of a  divestiture  of  KeySpan  Generation,  various
assumptions were made based on the current operating structure and relationships
between  KeySpan and each of its  subsidiaries  and  information  obtained  from
Mercer, a firm which provides  benchmarking data on U.S. energy company staffing
levels by  function  and  size.  A  discussion  of the key  assumptions  used to
estimate the lost economies is provided below.

B.  Spin-Off Assumptions

The study  assumes  that  KeySpan  Generation  will be  divested  as a  separate
stand-alone entity. Once divested,  this entity would operate as an independent,
publicly held,  and regulated  company.  It would have all necessary  management
personnel,  along  with  all  facilities,  equipment,  materials  and  supplies,
required to operate as a stand-alone, regulated electric generation company.


                                       7

1.   Staffing and Labor Costs

     For the purpose of determining  incremental  staffing  requirements for the
     stand-alone  company,  a sufficient  number of employees were assumed to be
     added to ensure  that LIPA  continued  to  receive  the  present  level and
     quality of service,  and that the direct  employees of the Company continue
     to utilize many of the same systems and processes in daily operations.  The
     labor  cost  estimates  for   additional   support  staff  are  based  upon
     assessments  of  straight-time,  incentive  compensation,  and  pension and
     benefit  costs for  current  holding  and  service  company  employees  and
     industry  benchmarking  data.  Given the continuing  tightness in the labor
     markets, the levels of incentive  compensation for executive staff included
     in this study may not be  reflective of the current  compensation  packages
     required to retain quality management in executive positions.

     Although KeySpan  Generation  benefits from the centralized  procurement of
     employee  benefits  provided  by a service  company,  for  purposes of this
     study, it was assumed that benefit levels and costs would remain  unchanged
     in the stand-alone organization.  In addition, the study assumes that labor
     costs for the direct  employees of the generation  company are not expected
     to change as well.

     The specific  cost  figures for  additional  support  staff labor costs are
     based on average salary figures from the parent and the Service  Companies,
     utility  benchmarking data provided by Mercer, and KeySpan's  experience in
     generation  company  management.  A  benefits-cost  adder was then applied,
     which was  developed  based on 1999 benefit  costs as a percentage of total
     wages and salaries for the parent and its Service  Companies.  Estimates of
     the portion of increased  labor  expenses that are likely to be capitalized
     are based on the percentage of allocated  common and  administrative  labor
     expenses that were capitalized by the Company in 1999.

2.   Engineering Expenses

     For the  most  part,  engineering  services  and  associated  expenses  are
     provided to KeySpan Generation by company employees on a dedicated,  direct
     charge  basis.  Therefore,  it was assumed  that such  employees  currently
     providing these services would be transferred to KeySpan Generation as part
     of the  divestiture  and  thus,  result  in no  incremental  costs  or lost
     economies.

3.  Capital Expenditures

     The majority of  increased  capital  expenditures  are most likely to arise
     from increased capitalized support staff labor expenses, higher procurement
     costs due to losses in purchasing  efficiencies,  and the need to separate,
     duplicate, and replace various information systems previously provided on a
     centralized  basis.  These  incremental  information  systems costs include
     computer  hardware,  software,  and systems  applications  for  centralized
     functions within the Service Companies (e.g.,  financial,  accounting,  and
     human  resources,  etc.)  which  must  be  performed  independently  in the
     stand-alone company.

<PAGE>


4.   Transition/Transaction Costs

     The  divestiture  of KeySpan  Generation  and the creation of a stand-alone
     utility would be a complex legal and financial transaction that would incur
     significant  transition  costs.  There  would be costs for  issuance of new
     equity  securities.  Other  transaction  costs  include legal and financial
     advisory fees,  fees for  independent  accountants,  actuaries,  investment
     bankers,  transfer taxes,  and title  insurance  fees. As discussed  above,
     KeySpan  Generation  would  incur  significant  costs to  either  purchase,
     duplicate,  or replace many of the information systems provided by KeySpan.
     KeySpan  Generation  would  experience  significant  costs for  hiring  and
     training the 84 additional staff required for stand-alone operations.

5.  Other Shareholder Costs

     The  divestiture  of KeySpan  Generation  would  create a new  independent,
     publicly  traded  company.  As  a  result,   KeySpan  Generation  would  be
     responsible for shareholder-related  costs including the issuance of annual
     reports and proxy  statements,  external  reporting to the  Securities  and
     Exchange    Commission,    annual    shareholder    meeting,    and   other
     investor-relations expenses.

6.  Cost Pass Through

     In estimating the impacts of additional costs on LIPA's  customers,  it was
     assumed that full pass through of the  increased  costs would be allowed in
     FERC rate proceedings and contract prices negotiated with LIPA beginning in
     2004, the sixth year of the PSA.

                                       10


<PAGE>


7.  Third-Party Contracts

     All existing  contracts  between  KeySpan  Generation and third parties are
     assumed to continue in the spun-off company.

III. Functions of the Service Companies

     While each company currently exists as a wholly-owned subsidiary within the
     KeySpan  organization,   certain  business  functions  are  provided  on  a
     consolidated basis to each subsidiary by the Service Companies. The Service
     Companies are an integral  part of KeySpan and serve to centralize  certain
     administrative  and  operational  functions in an effort to achieve  better
     organizational  efficiencies.  The Service Companies provide certain common
     corporate  administrative  services to KeySpan  Generation  including human
     resources  planning and  administration;  accounting,  finance and treasury
     services;  insurance  and  risk  management;  regulatory  and  governmental
     relations;  corporate  communications and external  relations;  information
     systems  and  technology;   materials  management  and  procurement;  legal
     services;  corporate and strategic planning; internal auditing; billing and
     payment  processing;   budget  administration;   security  services;  fleet
     services;   building   design   and   maintenance;    and   management   of
     affiliate-owned or leased buildings.

     Through this  centralized  administration,  the costs of such functions are
     shared  among the  KeySpan  companies  through  direct  and  indirect  cost
     allocation. Due to economies of scale, each company benefits from receiving
     these services at a lower cost than if it provided them on its own.

IV.  Analysis of Lost Economies from Divestiture on KeySpan Generation
     Overview

     KeySpan  Generation owns and operates an aggregate of 53 steam and internal
     combustion  electric generating units located throughout Long Island having
     a total capacity of approximately  4032 MW. KeySpan  Generation and KeySpan
     Gas  East   Corporation,   an  affiliate   that  provides  gas  service  to
     approximately  500,000  retail  customers  on  Long  Island,  have  a  long
     historical   relationship  because  their  gas  and  electric  assets  were
     originally owned and operated by LILCO on an integrated basis. When KeySpan
     acquired  these  assets in 1998,  they were  transferred  into the separate
     companies.  Substantially  all the employees of LILCO were also transferred
     to KeySpan and its affiliates in order to maintain and enhance efficiencies
     of operations.  Currently,  ten out of eleven of KeySpan Generation's steam
     generating plants are capable of burning gas to generate electricity.

     KeySpan  Generation  provides electric  capacity,  energy  conversion,  and
     ancillary services to LIPA pursuant to the PSA. Under the terms of the PSA,
     LIPA has the option of electing to  "ramp-down"  the  capacity it purchases
     from KeySpan Generation  beginning in 2005, year seven of the PSA. In years
     seven  through  ten of the  PSA,  if  LIPA  elects  to  ramp-down,  KeySpan
     Generation is entitled to receive  payment for 100% of the present value of
     the capacity charges  otherwise payable over the remaining term of the PSA.
     In years 11 through 15 of the PSA,  if LIPA elects to  ramp-down,  capacity
     charges  otherwise  payable by LIPA will be reduced.  Capacity  released in
     accordance with the ramp-down  provisions of the PSA may be used by KeySpan
     Generation  to bid on new LIPA  capacity  requirements  or to bid on

                                       12

<PAGE>


     LIPA's capacity  requirements  to replace other  ramped-down  capacity.  If
     KeySpan Generation continues to operate the ramped-down  capacity,  the PSA
     requires it to use  reasonable  efforts to market the  capacity  and energy
     from the  ramped-down  capacity  and to share any  profits  with  LIPA.  In
     addition, pursuant to the terms of the Generation Purchase Right Agreement,
     entered into in June 1997 and effective May 1998, (the "GPRA"), LIPA has an
     exclusive one year option to purchase all outstanding  membership interests
     in KeySpan  Generation  beginning May 28, 2001. The GPRA also provides that
     until  such  option  expires,  all  or any  part  of  KeySpan  Generation's
     membership  interests  may  not be sold or  transferred  to  non-affiliates
     without  LIPA's  prior  consent.   Therefore,   a  divestiture  of  KeySpan
     Generation  without  LIPA's consent would violate the terms of the GPRA and
     subject the Company and KeySpan to  liability  for breach of the GPRA.  The
     amount of such potential liability cannot be quantified.  Accordingly,  the
     significant  increase in costs that would be occasioned by a divestiture of
     KeySpan  Generation  would  adversely  affect its ability to compete in the
     long-term and could further  result in the payment of damages for violating
     the provisions of the GPRA.

     As a subsidiary of KeySpan,  many administrative and operational  functions
     are performed for KeySpan  Generation by the Service  Companies.  Thus, the
     majority  of  increased  costs  from  divestiture  result  from the need to
     replace service-company related personnel and resources with staff directly
     employed or hired by KeySpan Generation.

                                       13

<PAGE>


     Organizational and Staffing Impact

     Currently,  KeySpan  Generation has approximately 940 direct employees.  If
     KeySpan  Generation  were spun-off from  KeySpan's  system as a stand-alone
     entity,  it would need to expand its  organizational  structure  to add the
     executive,  administrative,  and operational staff to perform the functions
     it currently receives from the parent and the Service  Companies.  Based on
     our   analysis,   it  is   estimated   that  a  total  of  268   additional
     service-related personnel would be needed for KeySpan Generation to operate
     as a stand-alone company. Of the 268 employees, 184 employees are currently
     allocated to KeySpan  Generation  by the parent and the Service  Companies.
     Therefore, a total of 84 employees would be considered incremental.

     KeySpan Generation's  organizational  structure as of December 31, 1999 was
     used as a pattern  for  developing  the new  stand-alone  organization.  To
     support  a  stand-alone  corporate  structure,  an  additional  staff of 84
     employees would be required to perform  service company related  functions.
     Table 3 provides a breakdown  of the  incremental  additions  by  executive
     position.  The new areas and their  relationship  to the  December 31, 1999
     KeySpan Generation  organizational  structure are summarized in Table 3 and
     the discussion below.

Board of Directors

The Board of  Directors  is assumed to  consist of 6  directors  (2 inside and 4
outside) based on the size and scope of KeySpan Generation.

Chief  Executive  Officer  (CEO):  The CEO  position  would  report  to  KeySpan
Generation's  Board of Directors.  The CEO would be responsible for representing
the  corporation  to LIPA, the financial  community,  regulators and the public.
This position  would have  reporting  relationships  with the new executives and
staff added as a result of the divestiture.

Chief  Operating  Officer  (COO):  The COO would report  directly to the CEO and
would be responsible for the overall  operating  activities of the company.  The
COO position would oversee the work of two vice  presidents:  the Vice President
of Operations and the Chief Information Officer.

                                       15


<PAGE>


Vice  President  (VP) of Operations  would  oversee the mailroom,  reproduction,
purchasing,  facilities management,  and materials management functions, as well
as the real estate  function,  and the 8  additional  staff  (including  the VP)
required to perform these activities.

Chief  Information  Officer  (CIO)  would  be  responsible  for the  information
technology  needs  of  KeySpan  Generation.  This  position  would  oversee  all
information  systems,   communication  systems,  data  processing,   application
development, and software and hardware procurement within the KeySpan Generation
organization.  Approximately,  27 staff  positions  (including  the VP) would be
added to support the  information  technology  needs of KeySpan  Generation as a
stand-alone company.

Chief Financial Officer (CFO): The Chief Financial Officer would report directly
to the CEO and  would be  responsible  for  corporate  finance,  treasury,  risk
management,  accounting,  internal auditing,  investor relations,  and corporate
planning.  The CFO would oversee the work of the VP of Finance and Treasury, the
Controller,  and two  directors:  the  Director  of Investor  Relations  and the
Director of Corporate Planning.

VP of Finance and Treasury  position would incorporate the role of Treasurer and
corporate  finance,  including risk management,  claims,  and financial systems.
This position would be in charge of all financing,  both debt and equity for the
new corporate entity.  Approximately 8 (including the VP) new positions would be
needed in this organization.

                                       16


<PAGE>


Controller would assume the  accounting-related  functions currently directed by
KeySpan's Controller.  The Controller would oversee all accounting,  transaction
processing,  internal  auditing,  external  reporting,  and tax functions of the
Company.  An additional  23  (including  the  Controller)  management  and staff
positions would be required to support these accounting and processing services.

Director  of  Investor   Relations   would   handle  all   financial   corporate
communications  and  would be in charge  of  producing  the  Annual  Report  and
organizing  the annual  stockholder  meetings.  An  additional 2 (including  the
Director) positions would be required to support these services.

Director of Corporate  Planning would be responsible for strategic and financial
planning and budgeting.  Except for the director, no incremental positions would
be required to support these services.

VP/General  Counsel and Secretary  would report directly to the CEO and would be
responsible  for overseeing  legal affairs,  government  affairs,  and corporate
communications.  The General Counsel and Secretary would also be responsible for
all  corporate  legal  matters,   environmental   compliance,   SEC  compliance,
litigation,  state and  federal  regulatory  matters,  labor and  benefit  legal
matters,  contracts and corporate governance.  The General Counsel and Secretary
would oversee all legal services procured from outside attorneys. A new director
position under the General  Counsel would be created to consolidate the external
affairs,  corporate affairs,  corporate  communications,  and policy development
work of  KeySpan  Generation.  The  Director  of

                                       17


<PAGE>


External Affairs and Policy  Development would report to the General Counsel and
Secretary.  Except for the VP/General Counsel,  the Director of External Affairs
and Policy Development,  and a secretarial  position,  no other additional staff
would be required in this organization.

VP of Human  Resources:  The VP of Human  Resources would report directly to the
CEO and  would  be  responsible  for  compensation,  benefits,  staffing,  labor
relations,  training, employee relations,  organizational planning & design, and
health & safety services.  Three director  positions would be created to head up
these areas:  the director of compensation  and benefits;  the director of labor
and  employee  relations;  and the  director  of employee  staffing,  training &
development,  who would also be responsible for organization  planning & design,
and health & safety services.  The spin-off of KeySpan  Generation would require
an additional staff of 7 (including the VP) within the Human Resources function.

Facilities Impact

If KeySpan Generation were to spin-off from KeySpan, a new office location would
be required to accommodate 268 management and  administrative  personnel.  It is
estimated that  approximately  36,600 sq. ft. would be required based on 137 sq.
ft. per  employee.  The estimated  cost for this space is  $1,097,417  per year.
However,  when  compared  with the  current  allocation  of  $368,142  for lease
expenses to KeySpan  Generation  from the Service  Companies,  the net effect on
KeySpan Generation is an increase of $729,275 in annual lease expenses.


                                       18
<PAGE>

Information Technology - Non-labor/Outside Services

KeySpan  Generation would experience  significant  non-labor cost increases as a
result of the need to assume full responsibility for the information  technology
functions   currently  provided  by  the  Service   Companies.   The  additional
labor-related  costs have already been  incorporated into the labor cost figures
reflected  above.  Many of these  non-labor  costs would be one-time  transition
costs for the replacement and duplication of central systems currently  operated
and maintained by the Service Companies. These systems, which would be separated
and/or duplicated for KeySpan  Generation,  include the following:  employee and
human resources,  payroll, purchasing,  inventory,  project accounting,  general
ledger, accounts receivable, budgeting, and fixed asset accounting. The costs to
separate,  replace,  and  duplicate  all  these  systems  are  estimated  to  be
approximately  $21  million.  Assuming the systems are  depreciated  on the same
basis as that used by  KeySpan,  the  annual  depreciation  costs  would be $2.1
million.  While the majority of these information technology related costs would
be one-time transition costs, annual maintenance and lease costs (which have not
been factored into the projected expense  calculation) are expected to be higher
for the  stand-alone  company.  Currently,  KeySpan  outsources a portion of its
computer help desk function, however, it is uncertain whether KeySpan Generation
would be able to continue this arrangement on a stand-alone basis at its current
cost. In addition,  KeySpan  Generation  would lose the  opportunity  to jointly
develop new  applications  and share the cost of those  applications  with other
corporate entities.





                                       19
<PAGE>

Transition/Transaction Costs

The divestiture of KeySpan Generation and the creation of a stand-alone  utility
would be a  complex  legal  and  financial  transaction  that  would  result  in
significant  transition  costs. The costs for issuance of new equity  securities
are based on standard fees for similar  transactions by other  utilities.  Other
transaction   costs  include  legal  and  financial   advisory  fees,  fees  for
independent  accountants,  actuaries,  investment bankers, and transfer tax, and
title  insurance  fees.  As  discussed  above,  KeySpan  Generation  would incur
significant  costs  to  either  purchase,  duplicate,  or  replace  many  of the
information systems provided by the Service Companies.  KeySpan Generation would
experience  significant  costs for hiring and training the 84  additional  staff
required  for  stand-alone  operations.  The costs  associated  with  hiring and
training  were  estimated to be 10% of a new hire's  first year salary.  Table 4
sets  forth the  transition/transaction  costs  that  would be  applicable  in a
spin-off of KeySpan Generation.

Summary of Impacts for KeySpan Generation Spin-Off

The study  illustrates that a spin-off of KeySpan  Generation into a stand-alone
company would require an additional 84 full-time management and staff positions.
Based on the assumptions  set forth in Section II and the staffing  requirements
outlined  in Table 3, the  annual  cost  increase  if  KeySpan  Generation  were
spun-off  into a  stand-alone  entity is  estimated  to be  approximately  $17.4
million.  The  categories  of cost  increases are set forth in Tables 5, 6 and 7
below.

Exhibit K
Proposed Form of Notice

SECURITIES AND EXCHANGE COMMISSION

(RELEASE NO. 35-             )

FILING UNDER THE PUBLIC UTILITY HOLDING COMPANY ACT OF 1935
March 6, 2000




         KeySpan Corporation  ("KeySpan"),  One MetroTech Center,  Brooklyn, New
York  11201,  a New York  corporation  and  currently a public  utility  holding
company  exempt from  registration  under the Act  (except  for Section  9(a)(2)
thereof)  pursuant  to  Section  3(A)(1) of the Act and Rule 2  thereunder,  ACJ
Acquisition  LLC  ("ACJ"),  a direct  wholly-owned  subsidiary  of KeySpan,  and
Eastern Enterprises ("Eastern"), 9 Riverside Road, Weston,  Massachusetts 02493,
a  Massachusetts  voluntary  association  and a public utility  holding  company
exempt  from  regulation  under the Act (except  for  Section  9(a)(2)  thereof)
pursuant to Section 3(a)(1) of the Act and Rule 2 thereunder, have jointly filed
an application-declaration under sections 9(a)(2) and 10 of the Act.

         The  application-declaration  seeks approvals  relating to the proposed
acquisition,  pursuant  to which  Eastern  will  become a  direct,  wholly-owned
subsidiary of KeySpan (the "Transaction"). Specifically, KeySpan and ACJ request
authorization  and  approval  of the  Commission  to  acquire,  by  means of the
Transaction,  all of the issued and  outstanding  common  stock of Eastern  and,
indirectly,  all of the common stock of Eastern's utility  companies.  Following
completion  of the  Transaction,  KeySpan  will  register  as a holding  company
pursuant to Section 5 of the Act. KeySpan also requests  Commission approval for
the retention by KeySpan of the existing businesses, investments and non-utility
activities of KeySpan and Eastern under Section 11(b).

         On January 5, 2000, Eastern filed an  application/declaration  with the
Commission ("Eastern/EnergyNorth Application") requesting authorization pursuant
to Sections  9(a)(2) and 10 of the Act to acquire all the issued and outstanding
common stock of EnergyNorth,  Inc. ("EnergyNorth") (hereafter referred to as the
"ENI Transaction"). If the Commission approves the ENI Transaction,  EnergyNorth
will  become a  direct  subsidiary  of  Eastern,  and,  therefore,  an  indirect
subsidiary  of  KeySpan  through   consummation  of  the  Transaction.   In  the
Eastern/EnergyNorth Application, Eastern and EnergyNorth have requested that the
Commission  find that each will continue to be exempt  holding  companies  under
Section  3(a)(1)  of the  Act.  KeySpan  requests  that to the  extent  that the
Commission grants Eastern and EnergyNorth  exemptions under Section 3(a)(1), the
Commission  confirm that Eastern and  EnergyNorth  will  continue to qualify for
exemptions  under Section 3(a)(1)  following the consummation of the Transaction
and KeySpan's registration as a holding company.

<PAGE>


         Likewise,  KeySpan requests the Commission's  confirmation that KeySpan
Energy Corporation ("KEC"), a direct,  wholly-owned  subsidiary of KeySpan, will
continue  to be an exempt  holding  company  under  Section  3(a)(1)  of the Act
following  consummation  of the  Transaction.  KEC is a  holding  company  which
directly owns 100% of the  outstanding  voting  securities of The Brooklyn Union
Gas  Company  ("Brooklyn  Union"),  a gas utility  company  which  operates  gas
distribution facilities,  and sells gas at retail, within the state of New York.
KEC is currently an exempt holding  company under Section 3(a)(1) of the Act and
Rule 2.

         Pursuant to the Agreement and Plan of Merger dated November 4, 1999, as
modified by  Amendment  No.1 dated  January 26, 2000 (the  "Merger  Agreement"),
KeySpan,  through  ACJ,  will acquire all of the issued and  outstanding  common
stock of Eastern in an all-cash  transaction.  The Merger Agreement provides for
Eastern to be merged with and into ACJ with Eastern being the surviving  entity.
Eastern will then become a wholly,  owned direct  subsidiary of KeySpan.  Shares
held by Eastern,  KeySpan, or any of KeySpan's wholly-owned subsidiaries will be
cancelled in the Transaction.

         According to the Merger  Agreement,  Eastern  shareholders will receive
$64.00 in cash, without interest, for each share of Eastern common stock, unless
the  shareholder  is entitled to and has  perfected  its  dissenters'  appraisal
rights.  Eastern  shareholders  will  receive  an  additional  $0.006  per share
("Additional  Amount")  for each day the  Transaction  has not closed  after the
later of (a) August 4, 2000 or (b) ninety  days after the New  Hampshire  Public
Utilities   Commission   ("NHPUC")  gives  final  regulatory   approval  to  the
Eastern/EnergyNorth  Transaction, though the aggregate Additional Amount will be
reduced  by the  aggregate  amount of any per  share  increase  in any  dividend
actually paid that is attributable to any period in which the Additional  Amount
accrues.

         KeySpan is a  diversified  public  utility  holding  company which owns
three public utility  companies:  Brooklyn Union,  KeySpan Gas East  Corporation
d/b/a Brooklyn Union of Long Island ("KeySpan Gas East") and KeySpan Generation,
LLC  ("KeySpan  Generation").  Together,  Brooklyn  Union and  KeySpan  Gas East
distribute  natural gas to approximately 1.6 million retail  customers.  KeySpan
Generation sells electricity and capacity at wholesale to one customer, the Long
Island  Power  Authority  (which is a state  agency  that  resells the energy at
retail).

         KeySpan has sixteen (16) direct non-utility  subsidiaries which, either
directly or  indirectly,  engage in energy  related  business.  The  non-utility
subsidiaries  are as follows:  KeySpan  Energy  Corporation;  KeySpan  Operating
Services LLC; KeySpan Exploration and Production LLC; KeySpan Corporate Services
LLC; KeySpan Utility Services LLC; KeySpan Electric Services LLC; KeySpan Energy
Trading Services LLC; Marquez  Development  Corporation;  Island Energy Services
Company,   Inc.;   LILCO   Energy   Systems   Inc.;   KeySpan-Ravenswood   Inc.;
KeySpan-Ravenswood  Services Corp.; KeySpan Energy Supply LLC; KeySpan Services,
Inc.; Honeoye Storage  Corporation;  and, KeySpan

                                       2
<PAGE>


Technologies LLC. In addition, KeySpan's gas utility subsidiary, Brooklyn Union,
owns all or part  interests  in three  (3)  subsidiaries  that  are  engaged  in
non-utility businesses.

         For the year  ended  December  31,  1999,  KeySpan  reported  operating
revenues  of $3.0  billion of which $1.8  billion  (or  approximately  59%) were
derived from regulated sales of gas and gas  transportation,  and $861.6 million
(or approximately 29%) were derived from electric operations.  In the year ended
December 31, 1999,  KeySpan had an  operating  income of $482.2  million and net
income of $258.6 million.  At December 31, 1999, KeySpan had consolidated assets
of $6.7  billion,  including  net property and  equipment  of $4.2  billion.  At
December 31, 1999,  KeySpan had issued and  outstanding  133.9 million shares of
common  stock,  par value $0.01 per share.  KeySpan's  common  stock is publicly
traded on the New York Stock Exchange and the Pacific Stock Exchange.

         Eastern conducts all of its business  activities  through its operating
subsidiaries.  Eastern  currently  owns all of the  outstanding  common stock of
three gas utility companies operating exclusively within  Massachusetts:  Boston
Gas Company,  Colonial Gas Company and Essex Gas Company (collectively  referred
to  herein  as  the  "Massachusetts  Utilities").  Together,  the  Massachusetts
Utilities serve approximately 734,000 retail gas customers. Eastern has four (4)
wholly-owned,  material non-utility  subsidiaries:  Midland  Enterprises,  Inc.,
Transgas Inc., AMR Data Corporation and ServicEdge Partners,  Inc. The principal
non-utility  activities of Eastern's  subsidiaries are water barging activities,
including  the hauling of fuel and other  cargo;  transporting  by truck LNG and
propane;  providing  meters and meter reading  services to municipal  utilities;
and, providing heating, ventilation and air conditioning services.

         For the year ended December 31, 1998,  Eastern  reported gross revenues
of $935,264,000,  of which $667,106,000 (or approximately 71%) were derived from
regulated  sales  of  gas  and  gas   transportation,   operating   earnings  of
$100,405,000,  and  earnings  before  extraordinary  items  of  $50,828,000.  At
December 31, 1998, Eastern had consolidated assets of $1,518,370,000,  including
net property and equipment of $975,749,000.  On an unaudited  adjusted basis, to
take into account  financial  results of Colonial Gas, which Eastern acquired in
August 1999, Eastern would have had $1,118,357,000 in gross revenues,  including
$835,000,000,   or  75%  of  the  total,   from  regulated  gas  sales  and  gas
transportation.  At September  30, 1999,  Eastern had  adjusted  combined  total
assets of  $1,908,495,000,  including  adjusted net  property  and  equipment of
$1,269,101,000.1  At  December  31,  1999,  Eastern  had issued and  outstanding
27,114,198  shares of common stock, par value $1.00 per share.  Eastern's shares
are listed for  trading on the New York,  Boston and  Pacific  Stock  Exchanges;
however,   they  will  be  delisted  and  cease  to  be  publicly  traded  after
consummation of the Transaction.

occurred January 1, 1998.

<PAGE>

         If the Eastern/EnergyNorth Transaction is consummated, EnergyNorth will
be a direct,  wholly-owned subsidiary of Eastern.  EnergyNorth,  a New Hampshire
corporation,  owns all of the issued  and  outstanding  common  stock of one gas
utility company: EnergyNorth Natural Gas, Inc ("ENGI"). ENGI distributes natural
gas to approximately 72,000 residential,  commercial and industrial customers in
27 cities and towns  located in southern  and central New  Hampshire,  including
Nashua, Manchester, Concord and Laconia.

         EnergyNorth's material non-utility subsidiaries are principally engaged
in installing and servicing commercial heating, ventilation and air conditioning
