     Pursuant to Sections  9(a)(2) and 10 of the Public Utility  Holding Company
Act of 1935 (the "Act"), NSTAR ("NSTAR"), a Massachusetts business trust, hereby
requests that the Securities and Exchange Commission (the "Commission" or "SEC")
authorize the acquisition by NSTAR of the outstanding  voting  securities of BEC
Energy  and  Commonwealth  Energy  System  ("COM/Energy"),  and  issue  an order
exempting  NSTAR from all  provisions  of the Act except  Section  9(a)(2) under
Section 3(a)(1) following the consummation of the acquisition described herein.

Item 1. DESCRIPTION OF PROPOSED TRANSACTIONS

     A. Description of the Parties

          1. NSTAR

     NSTAR,  a  Massachusetts  business  trust,  is an  unincorporated  business
organization with transferable shares.  NSTAR has three subsidiaries:  (1) NSTAR
Delaware LLC, a limited  liability  company organized under Delaware law ("NSTAR
Delaware"),  of which  NSTAR  owns  100% of the  membership  interests;  (2) BEC
Acquisition LLC, a limited liability  company organized under  Massachusetts law
("BEC  Energy  Merger  Sub"),  of which  NSTAR  owns  99.99%  of the  membership
interests and NSTAR Delaware owns the remaining 0.01% membership  interest;  and
(3)  CES  Acquisition  LLC,  a  limited   liability   company   organized  under
Massachusetts law ("COM/Energy  Merger Sub" and, together with BEC Energy Merger
Sub, the "Merger Subs"), of which NSTAR owns 99.99% of the membership  interests
and NSTAR Delaware owns the remaining 0.01% membership interest.  Currently, BEC
Energy and COM/Energy together own all of NSTAR's issued and outstanding shares.
Upon the completion of the proposed transaction, both BEC Energy and COM/Energy,
through  mergers  with  BEC  Energy  Merger  Sub  and  COM/Energy   Merger  Sub,
respectively,  will become wholly-owned subsidiaries of NSTAR, and NSTAR will be
the new holding company for the combined business.

          2. BEC Energy

     BEC Energy, a Massachusetts  business trust, is an unincorporated  business
organization with transferable  shares. BEC Energy conducts its business through
its  operating  subsidiaries.  BEC Energy's  principal  subsidiaries  are Boston
Edison Company ("Boston Edison"), a regulated utility company, and Boston Energy
Technology Group, Inc. (also referred to in this document as "BETG"). BEC Energy
has received an order from the  Commission  exempting it from all  provisions of
the Act other than Section 9(a)(2) pursuant to Section 3(a)(1).1/

               (a) Utility Subsidiaries.

     Boston Edison Company:  Boston Edison,  a Massachusetts  corporation,  is a
public  utility  company  engaged  in the  generation,  purchase,  transmission,
distribution and sale of electric

energy in Massachusetts. Boston Edison's electric service territory covers about
590 square miles within 30 miles of Boston,  encompassing the City of Boston and
39  surrounding  cities and towns.  Boston Edison  serves some 663,000  electric
customers at retail.  Boston Edison also sells  electric  energy at wholesale to
other electric utilities and municipal electric departments under rate schedules
and tariffs on file with the Federal Energy Regulatory Commission (the "FERC").

     Boston Edison voluntarily  divested its fossil generation business pursuant
to a Settlement  Agreement  reached  with the  Massachusetts  Attorney  General,
Massachusetts  Division of Energy  Resources  and other  interested  parties and
filed on July 8, 1997 in  restructuring  proceedings  before  the  Massachusetts
Department of Telecommunications and Energy (the "MDTE"). The generation already
divested by Boston  Edison  included  1,987 MW of  fossil-fired  capacity at six
different  sites.  Boston  Edison  accomplished  the  divestiture  pursuant to a
competitive  bidding  procedure which resulted in the selection of Sithe Energy,
Inc. ("Sithe") as the winning bidder. The FERC granted approval for the transfer
of jurisdictional  transmission facilities related to the generation from Boston
Edison to Sithe in its Docket No.  EC98-16-000.  Boston  Edison's only remaining
owned-generation  is its 670 MW  Pilgrim  nuclear  power  plant.  Boston  Edison
recently  entered into an agreement to sell the Pilgrim  nuclear  power plant to
Entergy Nuclear Generation Company. If the requisite approvals for this sale are
not obtained,  it is likely that Boston Edison,  in the near future,  would shut
down the Pilgrim plant and permanently retire it.

     Boston  Edison also owns and operates  approximately  524 circuit  miles of
interconnected  transmission lines of 115-345 kV, including 176 circuit-miles of
230-345  kV  lines  and  348  circuit-miles  of 115 kV  lines.  Boston  Edison's
transmission  facilities  include  substations  with a capacity of approximately
3,500 MVA. All of these transmission facilities are located in Massachusetts.  A
map of Boston  Edison's  transmission  facilities  is included  in Exhibit  E-1.
Boston Edison's electric  distribution  system consists of approximately  22,003
circuit miles and substations with a capacity of approximately 10,822 MVA.

     Boston Edison also provides customers with transmission services, including
transmission  service under its Open Access  Transmission  Tariff and individual
contracts.  Boston Edison is a member of the New England  Power Pool  ("NEPOOL")
and has committed its pool  transmission  facilities  ("PTF") to the operational
control  of  ISO-New  England,  Inc.  ("ISO-New  England").   ISO-New  England's
principal  responsibilities  include  administration  of the NEPOOL  open access
transmission  tariff  ("NEPOOL  Tariff"),  the  operational  control  of the New
England  bulk  power  system,  protection  of  NEPOOL  system  reliability,  and
oversight of the New England Power  Exchange.2/  The NEPOOL Tariff  provides for
postage-stamp  rates which eliminate  pancaking of  transmission  charges in New
England thereby  creating a single power market that  encompasses  virtually the
entire  New  England  region.

2/   The FERC's order  authorizing the  establishment of ISO-New England and the
     transfer  of  operational  control  of the NEPOOL  grid to that  entity was
     issued on June 25, 1997.  New England Power Pool, 79 FERC P. 61,374 (1997);
     see also, New England Power Pool, on reh'g, 83 FERC P. 61,045 (1998), reh'g
     denied, 85 FERC P. 61,141 (1998). See, in addition, New England Power Pool,
     85 FERC P.  61,379  (1998)  order  conditionally  accepting  and  approving
     market-based rates.

                                        2

     The FERC  conditionally  approved  the  formation  of ISO-New  England  and
authorized,  on an interim  basis,  the  transfer  of  control  of  transmission
facilities  owned  by  the  public  utility  members  of  NEPOOL  as  part  of a
comprehensive  restructuring  of NEPOOL  on June 25,  1997.3/  On July 1,  1997,
ISO-New England was activated. Thus, although Boston Edison continues to own its
transmission facilities, PTF usage is and will be governed by ISO-New England.

     Harbor  Electric Energy  Company:  Harbor Electric Energy Company  ("Harbor
Electric"), a Massachusetts  corporation and a wholly owned subsidiary of Boston
Edison,  delivers electric energy from Boston Edison to the Massachusetts  Water
Resources  Authority  (the "MWRA"),  a large retail  customer.  Although  Harbor
Electric owns a small distribution  system,  that system is used exclusively for
distribution  to the MWRA. In addition,  Harbor  Electric owns no generation and
does not engage in wholesale sales or purchases.

               (b) Non-Utility Subsidiaries.

     Boston Energy Technology  Group,  Inc.: BEC also wholly owns an unregulated
subsidiary,  BETG.  BETG has  several  subsidiaries  and is  engaged  in various
businesses, including district energy and communications services. None of these
subsidiaries have any  jurisdictional  gas or electric utility  operations.  For
example, through a subsidiary,  BETG has entered into a telecommunications joint
venture with RCN Telecom Services, Inc. to provide telecommunications services.

     The common  shares,  $1.00 par  value,  of BEC Energy are listed on the New
York Stock  Exchange  ("NYSE")  and the Boston Stock  Exchange  under the symbol
"BSE". As of December 31, 1998 there were 47,184,073 common shares of BEC Energy
outstanding.

     For the year ended December 31, 1998, BEC Energy's  operating revenues on a
consolidated basis were approximately  $1.623 billion,  all of which was derived
from Boston Edison's and Harbor  Electric's  electric  operations.  Consolidated
assets  of  BEC  Energy  and  its   subsidiaries   at  December  31,  1998  were
approximately  $3.214 billion,  of which approximately $2.27 billion consists of
identifiable utility property, plant and equipment.

     A more  detailed  summary  of  information  concerning  BEC  Energy and its
subsidiaries is contained in the BEC Energy's Annual Report on Form 10-K for the
year ended  December  31,  1998,  which is  incorporated  herein by reference as
Exhibit H-1.

          3. COM/Energy

     COM/Energy,  a Massachusetts business trust, is an unincorporated  business
organization with transferable shares.  COM/Energy conducts its business through
its operating subsidiaries.

3/   See New England Power Pool, 79 FERC P. 61,374  (1997) reh'g  pending.  This
     order  found  that the New  England  ISO  proposal  met the  FERC's  eleven
     principles for ISOs, and conditioned  approval upon the ISO  establishing a
     self-funding mechanism.

COM/Energy  currently  claims an exemption  from all provisions of the Act other
than Section 9(a)(2) under Section 3(a)(1) pursuant to Rule 2.

     COM/Energy  holds  all  of the  stock  of  five  operating  public  utility
companies  (Cambridge  Electric  Light  Company  ("Cambridge  Electric"),  Canal
Electric   Company   ("Canal   Electric"),    Commonwealth    Electric   Company
("Commonwealth  Electric"),  Commonwealth Gas Company  ("Commonwealth  Gas") and
Medical Area Total Energy Plant,  Inc.  ("MATEP"))  and of several  subsidiaries
engaged in non-utility  businesses,  such as steam  distribution,  servicing and
processing of liquefied natural gas and the sale of energy products. Through its
utility  subsidiaries,  COM/Energy  serves  the  energy  needs of  approximately
600,000 customers in Eastern Massachusetts. COM/Energy's utility and non-utility
subsidiaries, all of which are wholly-owned, are described below:

               (a) Electric Utility Subsidiaries.

     COM/Energy's  three primary  generation owning  subsidiaries,  Commonwealth
Electric,  Cambridge  Electric,  and Canal Electric,  recently  divested most of
their generation assets, in a transaction that was approved by the FERC by order
dated  November  12,  1998 4/ and that  closed on  December  30,  1998.  A brief
description  of the  respective  companies'  generation  assets sold to Southern
Energy Canal,  L.L.C.  ("Southern  Canal") and Southern Energy  Kendall,  L.L.C.
("Southern  Kendall")  is provided  below by company.  Also set forth below is a
brief  description of each company's  remaining  generation  assets,  as well as
their  transmission and distribution  systems.  The sale of generating assets by
Commonwealth  Electric,   Cambridge  Electric,  and  Canal  Electric  and  their
restructuring  plans going forward are part of a  longstanding  intention of the
companies to divest their power supply portfolio.

     Commonwealth  Electric  Company:  Commonwealth  Electric,  a  Massachusetts
corporation,  is a franchised  public utility  company  engaged in the purchase,
transmission,  distribution  and  resale of power and  energy in  Massachusetts.
Commonwealth  Electric's  electric  service  territory covers about 1,100 square
miles in 40 communities  located in southeastern  Massachusetts,  including Cape
Cod  and  Martha's  Vineyard.  The  service  territory  includes  all or part of
Plymouth,   Bristol,  Barnstable  and  Duke  Counties  in  the  Commonwealth  of
Massachusetts.  Commonwealth  Electric serves some 327,000 electric customers at
retail in the Commonwealth of  Massachusetts.  Commonwealth  Electric also sells
electric  energy at wholesale to other electric  utilities  under rate schedules
and tariffs on file with the FERC but has no wholesale requirements customers.

         The FERC  approved  the  jurisdictional  aspects  of the sale of all of
Commonwealth  Electric's  generation  assets to  Southern  Canal by order  dated
November 12, 1998. The sale included the following  generation  facilities:  (1)
five  diesel  generating  plants at Oak  Bluffs  and West  Tisbury  on  Martha's
Vineyard,  Massachusetts  with a total  capacity  of 13.8 MW;  and (2) a 1.4325%
ownership  interest in the oil-fired William F. Wyman Unit 4 located in Yarmouth
Maine, operated by Central Maine Power Company. Commonwealth Electric's interest
in the

William F. Wyman Unit 4 translated  into a 8.9 MW  entitlement.  The transaction
with Southern Canal closed on December 30, 1998.

     Commonwealth  Electric also provides customers with transmission  services,
including  transmission  service  under its Open Access  Transmission  Tariff.5/
Commonwealth  Electric also owns and operates  approximately 357.5 circuit miles
of  interconnected  transmission  lines  of 115 kV to 345  kV,  including  297.6
circuit-miles  of  115  kV  lines  and  59.9  circuit-miles  of  345  kV  lines.
Transmission  facilities  include  substations  with a capacity of approximately
475,000  kilovolt-amperes.  All of these transmission  facilities are located in
Massachusetts.  A map of  Commonwealth  Electric's  transmission  facilities  is
included in Exhibit E-1.

     Commonwealth  Electric is a member of NEPOOL.  As explained above, the FERC
conditionally  approved the formation of ISO-New England and  authorized,  on an
interim basis,  the transfer of control of transmission  facilities owned by the
public utility  members of NEPOOL as part of a  comprehensive  restructuring  of
NEPOOL,  and on July 1, 1997,  ISO-New  England was  activated.  Thus,  although
Commonwealth Electric continues to own its transmission facilities, PTF usage is
governed  by ISO-New  England.  Commonwealth  Electric's  electric  distribution
system consists of  approximately  10,744 circuit miles and  substations  with a
capacity of approximately 1,814 MVA.

     Cambridge  Electric  Light Company:  Cambridge  Electric,  a  Massachusetts
corporation,  is a franchised  public utility  company  engaged in the purchase,
transmission,  distribution  and  resale of power and  energy in  Massachusetts.
Cambridge  Electric's electric service territory covers about 7 square miles. It
provides retail service in the City of Cambridge,  Massachusetts  to some 45,900
electric  customers.  In addition,  Cambridge Electric sells power for resale to
the Town of Belmont, Massachusetts, and through NEPOOL.

     As  mentioned  above,  the  FERC  approved  the  sale of most of  Cambridge
Electric's  generation  assets to Southern  Kendall by order dated  November 12,
1998.6/ Prior to the sale to Southern Kendall,  Cambridge Electric was primarily
a transmission and distribution utility.  However, it did own the 113 MW Kendall
Generating  Station and the 13.5 MW Blackstone  Station facility both located in
Cambridge, Massachusetts.  Cambridge Electric sold the 113 MW Kendall Generating
Station to Southern  Kendall as part of the transaction  that closed on December
30,  1998.  The  Blackstone  Station  facility  is  used  substantially  for the
production  of steam  for  resale  to  retail  customers.  Currently,  Cambridge
Electric is  reviewing  several  options with regard to the  Blackstone  Station
facility  and  will  seek  the  necessary  approvals  when  any  transaction  is
finalized.

     Cambridge  Electric also provides  customers  with  transmission  services,
including  transmission  service under its Open Access  Transmission  Tariff and
individual  contracts.  Cambridge  Electric is a member of NEPOOL.  As described
above in the  discussion on  Commonwealth  Electric's  transmission  facilities,
although Cambridge Electric  continues to own its transmission  facilities,  PTF
usage will be governed by ISO-New England.

     Cambridge  Electric also owns and operates  approximately 7.3 circuit miles
of  interconnected  transmission  lines  of  13.8  kV to  115  kV.  Transmission
facilities  include  substations  with  a  capacity  of  approximately   311,000
kilovolt-amperes.   All  of  these   transmission   facilities  are  located  in
Massachusetts. A map of Cambridge Electric's transmission facilities is included
in Exhibit E-1. Cambridge  Electric's  electric  distribution system consists of
approximately 584 circuit miles and substations with a capacity of approximately
218 MVA.

     Canal Electric Company: Canal Electric, a Massachusetts  corporation,  is a
public  utility  engaged in the purchase and sale of  electricity  at wholesale.
Canal Electric holds no franchise-  like authority and does not own,  operate or
control any transmission or  distribution.  Canal Electric sells electric energy
at wholesale to its affiliates  Cambridge  Electric and  Commonwealth  Electric,
under  rate  schedules  and  tariffs  on file  with the  FERC but has no  retail
customers. With the exception of an ownership interest in the Seabrook 1 nuclear
power facility,  Canal Electric recently divested its generation  interests in a

     B. Description of the Transaction

          1. Background of the Transaction

     Traditionally, electric utilities have operated under a monopoly regulatory
framework  under which  consumers have been  restricted to a single  electricity
provider,  typically a vertically  integrated  electric  utility  engaged in the
generation,  transmission and  distribution of electricity.  The electric energy
business has,  however,  become  increasingly  competitive  in recent years as a
result of industry restructuring and general economic trends. Boston Edison and,
following its formation in May 1998, BEC Energy,  and COM/Energy  have both been
anticipating  and  responding  to  such  changes.   In  1998,  pursuant  to  the
Massachusetts   Electric   Restructuring  Act,  each  company  extended  to  its
electricity  customers  the option of  choosing  their own  suppliers,  and each
company sold  substantially  all of its fossil electric  generating  plants.  In
addition,  Boston  Edison,  a  subsidiary  of BEC Energy,  has  entered  into an
agreement  to sell its  Pilgrim  Nuclear  Power  Station.  As a result  of these
divestitures,  the core electric  utility  business of each company will consist
substantially   of  the   distribution  and  the  transmission  of  electricity.
Competition  has also been extended  into some portions of the gas  distribution
industry in  Massachusetts,  and further  efforts to extend  competition  in the
natural gas industry are being  spearheaded by the  Massachusetts Gas Unbundling
Collaborative,  of which COM/Energy has been a key participant.  Since 1996, all
of  Commonwealth   Gas'  commercial  and  industrial   customers  have  had  the
opportunity  to acquire  gas from other  suppliers  and to have gas  transported
through Commonwealth Gas' distribution system.

     Under the Amended and Restated  Agreement  and Plan of Merger,  dated as of
December 5, 1998 and amended and restated as of May 4, 1999,  among  NSTAR,  BEC
Energy, COM/Energy, BEC Energy Merger Sub and COM/Energy Merger Sub (the "Merger
Agreement"),  at the Effective  Time (as defined  below),  BEC Energy will merge
with the BEC  Energy  Merger  Sub (the  "BEC  Merger"),  with BEC  Energy as the
surviving entity,  and COM/Energy will merge with the COM/Energy Merger Sub (the
"COM/Energy  Merger," and together  with the BEC Merger,  the  "Mergers"),  with
COM/Energy  as the  surviving  entity.  As a result of the  Mergers,  NSTAR will
become the direct and,  through  NSTAR  Delaware,  indirect  owner of all of the
outstanding  common  shares of BEC Energy and  COM/Energy;  NSTAR  Delaware will
shortly  thereafter  be  liquidated  and its interests in each of BEC Energy and
COM/Energy will thereby be transferred to NSTAR.  In this document,  we refer to
the time when the Mergers will be completed as the "Effective Time."

          2. Reasons for the Mergers

     As  previously  described,  as a result of industry  restructuring  and the
generation  plant  divestitures  by BEC Energy and  COM/Energy,  the  respective
managements and Boards of Trustees of BEC Energy and COM/Energy decided to focus
on their distribution business and to expand geographically, particularly in the
New England  area,  through  combinations  with other  electric and gas delivery
utilities.  The Boards of Trustees and  managements of BEC Energy and COM/Energy
each believe that the combination of BEC Energy's electric distribution business
with  COM/Energy's  electric and gas distribution  business will provide a basis
for NSTAR to become the premier  electric and gas  distribution  business in the
New England region and will

                                        9

<PAGE>



provide  strategic   financial   opportunities  for  both  companies  and  their
shareholders, as well as benefits to their customers and employees, including:

     o    Customer Service -- BEC Energy and COM/Energy expect that the combined
          enterprise  will be in a better  position  to offer  improved  service
          levels to  customers.  BEC  Energy  and  COM/Energy  believe  that the
          combined   enterprise's  broader  customer  base,  enhanced  financial
          resources  and  collective  experience  in serving the energy needs of
          communities  in eastern and  southern  Massachusetts  will allow it to
          invest more efficiently in technology and infrastructure.

     o    Potential Cost Savings and Cost Avoidances  Resulting from the Mergers
          -- BEC Energy and  COM/Energy  believe that the Mergers will result in
          net cost savings and cost avoidances  estimated at $500 million in the
          aggregate over a ten-year  period.  These  savings,  offset in part by
          annual  amortization  of  approximately  $20 million of the  estimated
          acquisition  premium,  will benefit customers because BEC Energy's and
          COM/Energy's rates are based on their costs of service.

     o    Competitive  and  Strategic  Position -- NSTAR will have a broader and
          more  diversified  customer base,  including  approximately  1,040,000
          electric  customers in 81 communities  and 240,000 gas customers in 51
          communities.  As a  result,  it will  have the size and scope to be an
          effective  competitor  in the  emerging and  increasingly  competitive
          markets for transporting and distributing  energy and marketing energy
          services.

     o    Expanded  Management  Resources  --  NSTAR  will  be able to draw on a
          larger  and more  diverse  pool of  management  for  leadership  in an
          increasingly competitive environment.

     As noted above, one of the more important potential benefits of the Mergers
is the cost savings expected to result from combining operations. Unlike some of
the other benefits mentioned above,  estimates of potential costs savings may be
quantified and  managements of BEC Energy and COM/Energy  developed  analyses of
potential cost savings as described below.

     Estimated  potential savings and avoidances  expected to be achieved by the
two companies  after the Mergers have been limited to quantifiable  amounts,  as
determined by the managements of BEC Energy and COM/Energy. Recognition has been
given to those costs to be incurred in  achieving  these  potential  savings and
avoidances  and to the time  required to implement  plans  designed to integrate
operations.  These  estimated  savings and  avoidances are  attributable  to the
Mergers and do not include other types of savings and  avoidances  that might be
achieved without a transaction  between the companies.  Operating synergies from
the Mergers are  estimated to generate net cost savings and cost  avoidances  of
$500  million  over a ten-year  period,  excluding  the annual  amortization  of
approximately  $20  million  of the  estimated  acquisition  premium.  The major
components of the anticipated cost savings and cost avoidances identified by the
managements of BEC Energy and COM/Energy are set forth below.


                                       10

     o    Integration of Corporate  Functions -- The combined  company will have
          the ability to  eliminate  redundant  functions in a variety of areas,
          including  accounting  and  finance,   human  resources,   information
          services,  external relations,  legal,  executive  management,  retail
          marketing,  and administrative  support. The staffing levels for these
          functions are  relatively  fixed and do not vary directly with changes
          in the number of employees or customers. The estimated cost savings of
          this  component  over the ten-year  period totals  approximately  $322
          million.

     o    Integration  of Corporate  Programs -- The combined  company will have
          the  ability  to  integrate  various   corporate  and   administrative
          functions,   thereby   reducing   non-labor  costs  in  the  areas  of
          advertising  and  public  relations,   benefits  plan  administration,
          insurance,  professional services,  facilities,  vehicles, association
          dues, and credit facilities.  In addition,  future expenditures in the
          area of  information  systems  that would be made by each company on a
          stand-alone basis will be reduced for the combined company. Additional
          expenditures will be reduced through the more efficient  management of
          investment in other technology areas,  including  personal  computers,
          other hardware and related software, and data center requirements. The
          estimated  cost savings of this  component  over the  ten-year  period
          totals approximately $211 million.

     o    Integration of Customer Support Functions -- The combined company will
          have the ability to integrate  customer support functions in the areas
          of customer service,  marketing and sales, and other support services,
          such as  purchasing  and  materials  management.  The  estimated  cost
          savings  of  this   component   over  the   ten-year   period   totals
          approximately $81 million.

     o    Streamlining of Inventories  and Purchasing  Economies -- The combined
          company  will have the  ability  to  centralize  some  purchasing  and
          inventory  functions.  Inventory may be shared across  locations.  BEC
          Energy and COM/Energy  expect purchasing power of the combined company
          to lead to materials and services volume discounts. The estimated cost
          savings  of  this   component   over  the   ten-year   period   totals
          approximately $53 million.

     BEC Energy and COM/Energy  will jointly  develop an integration  management
plan that will  examine  the  manner in which to best  organize  and  manage the
businesses of BEC Energy and COM/Energy  following the completion of the Mergers
and to identify duplicative positions in corporate and administrative functions.
BEC Energy and COM/Energy are committed to achieving cost savings and avoidances
resulting from  personnel  reductions  through  attrition,  strictly  controlled
hiring, reassignment, retraining, and voluntary separation programs.

     The  estimated  costs  savings and cost  avoidances  described  above total
approximately $667 million for the ten-year  estimation period, and are expected
to continue beyond the ten-year period following the merger.  Estimated costs to
achieve the Mergers total  approximately  $111 million over the ten-year period.
There are several  categories of costs included in the approximate total cost of
$111 million that BEC Energy and COM/Energy will incur to achieve the identified
savings that BEC Energy and COM/Energy expect from the Mergers. They include

                                       11

<PAGE>



separation costs, employee retention costs, system integration costs, relocation
costs, regulatory process costs, transaction costs, and transition costs. Of the
approximately   $111  million  of  estimated   costs  to  achieve  the  Mergers,
approximately $69 million will be incurred in 1999 and 2000.

     In addition, the combined company will incur the acquisition premium, which
is currently  estimated to be approximately $516 million,  over forty years. The
acquisition premium is the amount paid to COM/Energy shareholders in the Mergers
above the net book value of COM/Energy's assets and liabilities.

     Cost savings  initiatives  that BEC Energy or  COM/Energy  already  planned
prior to the Mergers were subtracted from the gross savings  estimated to result
from the  Mergers  because  there is likely  to be some  overlap  between  these
initiatives  and  identified  cost savings  resulting  from the  Mergers.  These
ongoing or future  initiatives will contribute to lower total costs to customers
and BEC Energy  and  COM/Energy  estimated  them to total $24  million  over the
ten-year period.

     The analyses  employed by the  managements  of BEC Energy and COM/Energy in
order to develop  estimates of potential savings as a result of the Mergers were
necessarily  based upon various  assumptions that involve judgments with respect
to, among other things,  future  national and regional  economic and competitive
conditions, inflation rates, regulatory treatment, weather conditions, financial
markets and other  uncertainties,  all of which are difficult to predict and are
beyond the control of BEC Energy and COM/Energy.  Accordingly,  while BEC Energy
and  COM/Energy  believe that such  assumptions  are  reasonable for purposes of
developing estimates of potential cost savings and cost avoidances, there can be
no assurance that such assumptions will  approximate  actual  experience or that
such cost savings and cost avoidances will be realized.

          3. Structure and Terms of the Mergers

     Pursuant to the Merger Agreement,  the combination of the operations of BEC
Energy and  COM/Energy  will be effected  through two mergers,  which will occur
simultaneously  at the  Effective  Time.  BEC Energy  will merge with BEC Energy
Merger Sub, and COM/Energy will merge with COM/Energy Merger Sub.

     (a) The BEC Energy  Merger.  At the Effective  Time,  BEC Energy will merge
with  BEC  Energy  Merger  Sub,  with BEC  Energy  continuing  as the  surviving
Massachusetts business trust. Each common share of BEC Energy (other than shares
held by BEC  Energy,  COM/Energy,  NSTAR or their  subsidiaries,  which shall be
canceled) that was issued and outstanding immediately prior to such merger shall
be converted into the right to receive either $44.10 in cash or one common share
of NSTAR,  and each 1% membership  interest in BEC Energy Merger Sub outstanding
immediately  prior to such merger  shall be  converted  into one hundred  common
shares of BEC  Energy.  Each common  share of NSTAR held by BEC Energy  shall be
canceled.  NSTAR  Delaware  will,  shortly  thereafter,  be  liquidated  and all
interests it holds in BEC Energy will thereby be transferred to NSTAR.


                                       12

<PAGE>



     (b) The COM/Energy  Merger.  At the Effective  Time,  COM/Energy will merge
with  COM/Energy  Merger Sub, with  COM/Energy  as the  surviving  Massachusetts
business trust.  Each common share of COM/Energy  (other than shares held by BEC
Energy, COM/Energy,  NSTAR or their subsidiaries,  which shall be canceled) that
was issued and outstanding  immediately  prior to such merger shall be converted
into the right to receive  either $44.10 in cash or 1.05 common shares of NSTAR,
and each 1% membership interest in COM/Energy Merger Sub outstanding immediately
prior to such  merger  shall be  converted  into one  hundred  common  shares of
COM/Energy.  Each common  share of NSTAR held by  COM/Energy  shall be canceled.
NSTAR  Delaware  will,  shortly  thereafter,  be liquidated and all interests it
holds in COM/Energy will thereby be transferred to NSTAR.

     As a  result  of the  Mergers,  each  BEC  Energy  common  share  and  each
COM/Energy common share (other than shares held by BEC Energy, COM/Energy, NSTAR
or their  subsidiaries and affiliates,  which will be canceled) will effectively
be converted  into the right to receive cash or common shares of NSTAR.  Subject
to certain  restrictions  on the amounts of cash and share  consideration  to be
issued,  described below, BEC Energy and COM/Energy shareholders will be able to
elect the type of consideration they will receive from NSTAR in the Mergers.

     The total cash consideration to be paid in connection with the Mergers will
be $300  million,  with $200  million to be paid to  shareholders  of BEC Energy
pursuant to the BEC Energy Merger,  and $100 million to be paid to  shareholders
of  COM/Energy  pursuant to the  COM/Energy  Merger.  Because the amount of cash
consideration  is fixed,  it is  possible  that some  shareholders  electing  to
receive cash in the BEC Energy Merger or the COM/Energy  Merger, as the case may
be,  may  receive  shares  of NSTAR in lieu of some or all of the cash that they
elected to receive and, conversely,  shareholders  electing to receive shares of
NSTAR may  receive  cash in lieu of some or all of the shares of NSTAR that they
elected to  receive.  In the event that  shareholders  of  COM/Energy  or of BEC
Energy make cash elections exceeding the cash consideration  initially allocated
to such  shareholders  (i.e.,  $200 million,  in the case of shareholders of BEC
Energy,  and $100 million in the case of shareholders  of  COM/Energy),  and the
shareholders  of the other company make cash  elections for less than all of the
cash consideration initially allocated to such shareholders,  some or all of the
cash  initially  allocated  to the  shareholder  group that  under-elected  cash
consideration may be allocated to the over-electing shareholder group.

     At the Effective Time, each  outstanding  option or other right to purchase
or receive BEC Energy  common shares shall be assumed by NSTAR in such manner as
to convert it into an option or other right to purchase or receive  NSTAR common
stock.  The options or other rights so converted  shall be exercisable  upon the
same terms and  conditions  which applied up until the Effective  Time,  and the
number of shares  issuable  under  such  options  or other  rights  will  remain
unchanged.

     The closing of the Mergers  (the  "Closing")  will take place on the second
Business day immediately  following the date on which the last of the conditions
set forth in the Merger  Agreement is fulfilled or waived,  at 10:00 a.m. at the
offices of Ropes & Gray, One International

                                       13

<PAGE>



Place, Boston, Massachusetts, or on such other date as BEC Energy and COM/Energy
mutually agree (the "Closing Date").

     On the Closing Date, certificates of merger complying with the requirements
of the  Massachusetts  Limited  Liability Company Act will be executed and filed
with the Secretary of the  Commonwealth  of  Massachusetts.  Each of the Mergers
shall  become  effective  at the time and date  agreed  upon by BEC  Energy  and
COM/Energy and set forth in the corresponding  certificates of merger;  provided
that the Mergers shall become effective simultaneously.

Item 2. FEES, COMMISSIONS AND EXPENSES

     The  fees,  commissions  and  expenses  of  NSTAR  expected  to be  paid or
incurred,  directly or indirectly, in connection with the transactions described
above are estimated as follows:

         Auditors' Fees......................................*
         Legal Fees......................................... *
         Investment Bankers' Fees and Expenses...............*
         Miscellaneous.......................................*
         Total...............................................*
         *To be filed by amendment.

Item 3. APPLICABLE STATUTORY PROVISIONS

     The following sections of the Act are directly or indirectly  applicable to
the proposed transactions: Sections 9(a)(2) and 10. To the extent other sections
of the Act or the  Commission's  rules  thereunder are deemed  applicable,  such
sections and rules should be considered to be set forth in this Item 3.

     Section 9(a)(2) makes it unlawful, without approval of the Commission under
Section  10,  "for any person . . . to  acquire,  directly  or  indirectly,  any
security of any public utility company,  if such person is an affiliate . . . of
such  company and of any other  public  utility or holding  company,  or will by
virtue of such  acquisition  become such an  affiliate."  Because NSTAR will, by
virtue of the Mergers,  become an affiliate of Boston Edison,  Harbor  Electric,
Cambridge   Electric,   Canal  Electric,   Commonwealth   Electric,   MATEP  and
Commonwealth  Gas,  Section 9(a)(2)  requires  approval by the Commission of the
proposed  transactions  under Section 10. NSTAR  believes that the  transactions
meet the requirements of Sections 9(a)(2) and 10.

     A. Section 10(b)

     Section  10(b)  provides  that if the  requirements  of  Section  10(f) are
satisfied,  the  Commission  shall  approve an  acquisition  under  Section 9(a)
unless:

          (1) such acquisition will 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 interests of investors or
     consumers;


                                       14

<PAGE>



          (2) in case of the  acquisition of securities or utility  assets,  the
     consideration,  including all fees, commissions, and other remuneration, to
     whomsoever  paid, to be given,  directly or indirectly,  in connection with
     such  acquisition is not reasonable or does not bear a fair relation to the
     sums  invested  in or the  earning  capacity  of the  utility  assets to be
     acquired or the utility assets underlying the securities to be acquired; or

          (3) such acquisition will unduly  complicate the capital  structure of
     the holding  company  system of the applicant or will be detrimental to the
     public  interest or the  interests  of investors or consumers or the proper
     functioning of such holding company system.

          1. Section 10(b)(1)

     The proposed transaction will not tend towards  interlocking  relationships
or concentrations of control that would be detrimental to the public interest or
the interest of investors or consumers for several reasons.

               (a) Interlocking Relationships

     By its  nature,  any  merger  results  in  new  links  between  theretofore
unrelated  companies.  Northeast  Utilities,  HCAR No. 25221 (Dec. 21, 1990), as
modified,  HCAR No. 25273 (March 15,  1991),  aff'd sub nom.  City of Holyoke v.
SEC, 972 F.2d 358 (D.C. Cir. 1992)("interlocking  relationships are necessary to
integrate [the two merging entities]").  These links, however, are not the types
of interlocking  relationships targeted by Section 10(b)(1), which was primarily
aimed   at   preventing   business    combinations    unrelated   to   operating
efficiencies.10/  The Merger  Agreement  provides  for the board of  trustees of
NSTAR to be composed of all of the members of the boards of trustees of both BEC
Energy and COM/Energy.  These management  interlocks are necessary and desirable
to integrate the existing utility operations of BEC Energy and COM/Energy into a
single integrated  public-utility system, and will 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).

               (b) Concentration of Control

     Section  10(b)(1) is intended to prevent  utility  acquisitions  that would
result in "huge, complex and irrational  systems",  American Electric Power Co.,
46 S.E.C.  1299,  1307  (1978),  and to avoid "an  excess of  concentration  and
bigness" while preserving "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.  Id. at 1309. In applying Section
10(b)(1) to utility

10/  See  Section  1(b)(4)  of the Act  (finding  that the public  interest  and
     interests  of  consumers  are  adversely  affected  "when  the  growth  and
     extension of holding  companies  bears no relation to economy of management
     and operation or the  integration  and  coordination  of related  operating
     properties . . .").

                                       15

acquisitions,  the Commission must determine whether the acquisition will create
"the type of  structures  and  combinations  at which  the Act was  specifically
directed." Vermont Yankee Nuclear Corp., 43 S.E.C. 693, 700 (1968).

     In Northeast  Utilities,  HCAR No. 25221 (Dec.  21, 1990),  the  Commission
stated that  "antitrust  ramifications  of an acquisition  must be considered in
light of the fact  that  public  utilities  are  regulated  monopolies  and that
federal and state administrative agencies regulate the rates charged consumers."
NSTAR's  utility  operations will be subject to regulation with respect to rates
and other  corporate  matters by the MDTE,  to protect the interest of consumers
and the public interest.  The public utility subsidiary  companies of BEC Energy
and  COM/Energy  are  currently,  and  following the proposed  transaction  will
remain, subject to the jurisdiction of the MDTE and the FERC.

     The Commission has watchfully deferred to the work of other regulators with
respect to  competition.  BEC Energy and COM/Energy have each filed a Pre-merger
Notification  and Report Form with the Antitrust  Division of the  Department of
Justice (the "DOJ") and the Federal Trade Commission (the "FTC") pursuant to the
Hart-Scott-Rodino  Act (the "HSR Act"). The applicable  waiting period under the
HSR Act was terminated on May 7, 1999. It is a condition to the  consummation of
the Mergers that the  applicable  waiting  periods  under the HSR Act shall have
expired or been terminated.

     In addition, the competitive impact of the Mergers will be fully considered
by the FERC  pursuant to Section  203 of the Federal  Power Act in its review of
the Mergers. As explained more fully in the FERC application, a copy of which is
attached  hereto as Exhibit  D-3,  the Mergers  will not  produce  any  material
increase  in  market  concentration,  and will not have any  adverse  effect  on
competition. As previously noted, the principal electric utility subsidiaries of
BEC Energy and COM/Energy have divested themselves of substantially all of their
generating  assets, and the Mergers therefore will not result in any significant
increase in market  concentration  for  generation.  These  electric  utilities,
moreover, are members of NEPOOL, and have committed their PTF to the operational
control of ISO-New England.  As previously noted,  ISO-New  England's  principal
responsibilities  include  administration of the NEPOOL Tariff,  the operational
control  of the New  England  bulk power  system,  protection  of NEPOOL  system
reliability,  and oversight of the New England Power  Exchange.  ISO-New England
also has planning and  congestion-management  responsibilities  and  maintains a
market monitoring function to protect against anti-competitive  practices by the
owners of the region's generating assets. ISO-New England is complemented by the
restructured NEPOOL whose objective is also to foster competition within the New
England region,  promote  attainment of the maximum possible economy of service,
and protect system  reliability.  These arrangements  create a competitive power
supply market that brings together power suppliers and electricity  consumers in
the New England  region.  The effect of those  arrangements is to create a power
supply  market  that  encompasses  the  entire  New  England  region,  and which
eliminates transmission market power through operation of the ISO.

     The Commission  has recognized  that there is no limit on size per se. On a
pro forma basis, giving effect to the proposed  transaction,  as of December 31,
1998, BEC Energy and COM/Energy  would have combined assets of $5.14 billion and
total operating revenue for the

                                       16

<PAGE>



year ended  December 31, 1998 of $2.42  billion and  approximately  1.04 million
electric utility customers and approximately  240,000 gas utility customers.  In
this case, as reflected in the table below, the proposed transaction will create
a system that is  comparable  to or smaller  than other  utility  systems in the
region.

</TABLE>


     The Commission has approved  acquisitions  involving much larger  operating
utilities  (see Entergy  Corp.,  HCAR No. 25952 (Dec.  17, 1993)  approving  the
acquisition  of  Gulf  States  Utilities,   with  combined  assets  at  time  of
acquisition in excess of $21 billion; The Southern Company, HCAR No. 24579 (Feb.
12, 1988)  approving the  acquisition of Savannah  Electric and Power Company to
create a system with assets of $20 billion and 3.25 million  customers)  and has
not found the size of other  existing  holding  companies  of similar size to be
problematic.12/

     For  these  reasons,   the  proposed  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 customers within the meaning of Section 10(b)(1).

          2. Section 10(b)(2) -- Fairness of Consideration

     Section  10(b)(2)   requires  the  Commission  to  determine   whether  the
consideration  to be given to the  holders of BEC Energy and  COM/Energy  common
shares in connection  with the Merger is reasonable  and whether it bears a fair
relation to the investment in and the earning

11/  The  material in this table with  respect to entities  other than NStar has
     been compiled from the most recent  Annual  Report to  Shareholders  and/or
     Form 10-K for each  entity.  While BEC Energy and  COM/Energy  believe  the
     figures in the table to be  accurate  and  comparable  to one  another,  an
     individual figure may differ somewhat from figures filed elsewhere in other
     contexts that may have been calculated in a different manner.


12/  The Southern Company System,  for example,  has assets of approximately $27
     billion and revenues of approximately $8.3 billion, while American Electric
     Power has assets of approximately $15.7 billion,  revenues of approximately
     $5.5 billion and  approximately  2.9 million  utility  customers.  Entergy,
     which as a result  of its  acquisition  of Gulf  States  Utilities  Company
     provides  service in the State of Texas,  currently has  approximately  2.4
     million utility customers.

capacity of the utility assets underlying the securities being acquired.  In its
determinations as to whether or not a price meets such standard,  the Commission
has  considered  whether  the price was  decided as the  result of  arm's-length
negotiations,13/  whether  each  party's  Board of  Directors  has  approved the
purchase  price,14/  the opinions of  investment  bankers15/  and the  earnings,
dividends, book and market value of the shares of the company to be acquired.16/

     The  fairness of the  consideration  involved in the Merger is evidenced by
the fact that the  exchange  ratios are the product of  extensive  and  vigorous
arm's-length  negotiations  between the parties,  and the Merger  Agreement  was
approved  by the  Boards of  Trustees  of BEC Energy  and  COM/Energy  acting in
accordance with their fiduciary duties to shareholders.  These negotiations were
preceded by thoughtful  analysis and evaluation of the assets,  liabilities  and
business  prospects of each of the companies and involved  careful due diligence
by both parties.  See NSTAR Registration  Statement on Form S-4 (incorporated by
reference as Exhibit C-1 hereto).

     In  addition,  nationally-recognized  investment  bankers  for  each of the
parties have reviewed extensive information  concerning the companies,  analyzed
the exchange ratios employing a variety of valuation  methodologies,  and opined
that the  exchange  ratios  are fair,  from a  financial  point of view,  to the
shareholders of the respective  companies.  The BEC Energy  investment  bankers'
opinion is  incorporated  by  reference  to/attached  hereto as Exhibit G-1. The
COM/Energy  investment bankers' opinion is incorporated by reference to/attached
hereto as Exhibit G-2.

     Finally,  a comparative  analysis of the values of BEC Energy common shares
and  COM/Energy  common  shares  demonstrates  the  fairness of the  conversions
ratios.

     shareholders  of Boston  Edison  exchanged  their  shares for shares of BEC

On December 4, 1998,  the last  business day  preceding  the day that the Merger
Agreement was entered into, BEC Energy common shares traded at a high of $42-1/4
and a low of $41-13/16,  with a closing price of $42;  COM/Energy  common shares
traded at a high of  $38-3/8  and a low of  $37-11/16,  with a closing  price of
$37-13/16.

     In light of the aforesaid  opinions,  and an analysis of all other relevant
factors,  NSTAR  believes  that the  exchange  ratios  fall  within the range of
reasonableness,  and that the consideration for the Merger bears a fair relation
to the sums invested in, and the earning capacity of, BEC Energy and COM/Energy,
respectively.

          3. Section 10(b)(2) -- Reasonableness of Fees

     NSTAR believes that the overall fees, commissions and expenses incurred and
to be incurred in connection  with the Mergers are  reasonable and fair in light
of the size and complexity of the Mergers relative to other transactions and the
anticipated benefits of the Merger to the public, investors and consumers;  that
they are consistent with recent  precedent,  and that they meet the standards of
Section 10(b)(2).

     As set  forth in Item 2 of this  Application,  BEC  Energy  and  COM/Energy
together expect to incur a combined total of approximately $-*- million in fees,
commissions and expenses in connection with the Mergers.  By contrast,  American
Electric Power Company and Central and South West  Corporation  have represented
that they expect to incur total transaction fees and regulatory  processing fees
of approximately $53 million, including financial advisory fees of approximately
$31 million, in connection with their proposed Merger.

     The Applicants  believe that the estimated fees and expenses in this matter
bear a fair  relation to the value of their  combined  company and the strategic
benefits to be achieved by the  Mergers,  and further that the fees and expenses
are fair and reasonable in light of the complexity of the Mergers. See Northeast
Utilities,  Holding Co. Act Release No. 25548 (June 3, 1992),  modified on other
grounds,  Holding Co. Act Release No. 25550 (June 4, 1992) (noting that fees and
expenses  must bear a fair  relation  to the value of the company to be acquired
and the benefits to be achieved in connection  with the  acquisition).  Based on
the price of BEC Energy and  COM/Energy  common shares on December 4, 1998,  the
Mergers would be valued at approximately $2.8 billion.  The total estimated fees
and expenses of $-*- million  represent  approximately  -*-% of the value of the
consideration to be paid to the  shareholders of BEC Energy and COM/Energy,  and
are consistent with  percentages  previously  approved by the  Commission.  See,
e.g., Entergy Corp., Holding Co. Act Release No. 25952 (Dec. 17, 1993) (fees and
expenses  represented  approximately 1.7% of the value of the consideration paid
to the shareholders of Gulf States Utilities);  Northeast Utilities, Holding Co.
Act  Release  No.  25548  (June 3, 1992)  (approximately  2% of the value of the
assets to be acquired).

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

generate  net cost savings and cost  avoidances  of $500 million over a ten-year
period,  will  provide a basis for the  combined  company  to become  one of the
premier gas and electric distribution  businesses in the New England region, and
will provide  strategic  financial  opportunities  for both  companies and their
shareholders,  as well  as  benefits  to  their  customers  and  employees.  The
transaction will

therefore  be in  the  public  interest  and  the  interests  of  investors  and
consumers,  and  will  not be  detrimental  to  the  proper  functioning  of the
resulting holding company system.

     B. Section 10(c)

     Section 10(c) of the Act provides that,  notwithstanding  the provisions of
Section 10(b), the Commission shall not approve:

          (1) an  acquisition of securities or utility  assets,  or of any other
     interest,  which is  unlawful  under  the  provisions  of  Section  8 or is
     detrimental to the carrying out of the provisions of Section 11; or

          (2) the  acquisition  of  securities  or  utility  assets  of a public
     utility  or  holding   company  unless  the  Commission   finds  that  such
     acquisition   will  serve  the  public  interest  by  tending  towards  the
     economical and the efficient  development  of an integrated  public utility
     system . . . .

          1. Section 10(c)(1)

     Section  10(c)(1)  requires that the proposed  acquisition not be "unlawful
under the  provisions of Section 8" or  "detrimental  to the carrying out of the
provisions  of Section 11." Section 8, by its terms,  only applies to registered
holding  companies and thus the proposed  transaction  cannot be unlawful  under
Section 8 of the Act. As  discussed  in more  detail  below in  connection  with
Section 10(f),  however,  even if Section 8 applied to exempt holding companies,
the  transaction  would not be unlawful as there is no state law,  regulation or
policy  against  combination  companies.  Section  11 of the Act  relates to the
simplification of holding company systems, and by its terms also only applies to
registered  holding  companies.  As discussed in more detail below in connection
with  Section  10(c)(2),   however,   this  transaction  will  tend  toward  the
development of an integrated public utility system.

          2. Section 10(c)(2)

     Section  10  analysis  requires  that the  acquisition  tend  "towards  the
economical and efficient  development of an integrated  public-utility  system."
The Commission has stated in several  cases,  including in the Gaz  Metropolitan
case, a seminal  decision in this area,  that under  Section  10(c)(2) an exempt
holding  company may consist of more than one integrated  system.18/ In essence,
Section 10(c)(2) requires that (i) each utility system within the exempt holding

     HCAR No. 26170 (November 23, 1994). In Gaz Metropolitan, the Commission has
     explicitly stated "[W]e have indicated in the past that acquisitions may be
     approved  even if the  combined  system  will  not be a  single  integrated
     system.  Section 10(c)(2)  requires only that the acquisition tend 'towards
     the   economical   and  the   efficient   development   of  an   integrated
     public-utility system' (emphasis added)."

company system be an integrated  system and (ii) the acquisition tend toward the
economical and efficient development of an integrated system.

     The term "integrated  public-utility system" is defined in Section 2(a)(29)
to mean:

          As applied to electric utility  companies,  a system consisting of one
          or more units of generating  plants and/or  transmission  lines and/or
          distributing  facilities,   whose  utility  companies  are  physically
          interconnected or capable of physical  interconnection and which under
          normal   conditions   may  be   economically   operated  as  a  single
          interconnected  and 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 advantage of localized management,  efficient operation,
          and the effectiveness of regulation;

          and

          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 effectuated 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 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.

     As the Commission and its staff have  previously  noted, in connection with
an acquisition by an exempt holding company, Section 10(c)(1) mandates that such
acquisition  not be detrimental to the carrying out of the provisions of Section
11,  but does not  require  that the  acquisition  meet the  strict  integration
standards  of Section  11(b)(1)  as would be required  of a  registered  holding
company. The Commission has previously determined that an exempt holding company
may acquire  utility  assets that will not,  when  combined  with the  acquiring
company's existing utility assets,  make up an integrated system or fully comply
with the strict integration  standards of Section 11(b)(1),  as long as there is
de facto  integration of contiguous  utility  properties and the holding company
will remain  exempt from  registration  under Section 3 of the Act following the
acquisition.  TUC Holding Company, HCAR No. 26749 (Aug. 1, 1997). The Commission
has previously  approved the acquisition of gas or electric utility companies by
existing combination exempt holding companies.19/

     Turning to the facts of the instant matter, the gas and electric operations
of BEC Energy and COM/Energy will separately form integrated utility systems and
the combined gas and electric system will not be detrimental to the carrying out
of Section  11.  NSTAR's  electric  system  will meet the  standards  of Section
2(a)(29)(A)  as the electric  operations  of BEC Energy and  COM/Energy  will be
integrated.

     There  are a number  of  physical  interconnections  between  the  electric
utility  subsidiaries  of BEC  Energy  and  COM/Energy.  There are two  physical
interconnections between the transmission systems of Boston Edison and Cambridge
Electric,  occurring at Boston Edison's North  Cambridge  Substation 509 and its
Somerville  Substation 402. Substation 509 connects Cambridge  Electric's 115 kV
facilities  with Boston  Edison's  115 kV  facilities.  Substation  402 connects
Cambridge Electric's 13.8 kV lines with Boston Edison's 13.8kV facilities.

     There  are  several  physical  interconnections  between  the  transmission
systems  of  Commonwealth  Electric  and  Boston  Edison.  In the  Cape  Cod and
Plymouth/Carver  area,  Commonwealth  Electric has 345 kV interconnections  with
Boston Edison  through lines 342 and 355 in Plymouth,  Massachusetts,  and lines
331 and 322 in Carver,  Massachusetts.  Commonwealth  Electric also has a 115 kV
interconnection  with  Boston  Edison in  Whitman,  Massachusetts.  Commonwealth
Electric and Boston Edison jointly own a transmission  line,  referred to as the
"Card  Street"  line,  which  runs  from  West  Medway,   Massachusetts  to  the
Massachusetts-Rhode Island border in Uxbridge, Massachusetts.

     MATEP purchases electric power from Boston Edison from time to time both as
a backup power supply and at times when the cost of purchasing  electricity from
Boston  Edison  is less  expensive  than  the cost of  producing  it in order to
fulfill  MATEP's  power supply  obligations  to its  customers.  MATEP's 13.8 kV
distribution  system is physically  interconnected  with Boston Edison's 13.8 kV
distribution system at a number of locations.  In addition to an interconnection
at MATEP's facility,  there are interconnections between the two systems at each
of MATEP's customers' facilities.

     Moreover,  with the  exception of Harbor  Electric and MATEP,  the electric
utility  subsidiaries  of both BEC Energy and of  COM/Energy  are all members of
NEPOOL. The Commission has previously determined that electric utilities with no
actual physical  interconnection may be "operated as a single interconnected and
coordinated system through . . . participation in NEPOOL" and thereby qualify as
an integrated electric utility system. UNITIL Corporation, HCAR No. 25524 (April
24, 1992).

     NSTAR's  gas  system  will  meet  the  standards  of  Section  2(a)(29)(B).
COM/Energy is an existing exempt  combination  holding  company,  owning several
electric utility subsidiaries and

                                       23

<PAGE>



one gas  utility,  Commonwealth  Gas. BEC Energy is an exempt  electric  utility
holding company, and has no gas utility subsidiaries.

     Commonwealth   Gas   operates   entirely   within   the   Commonwealth   of
Massachusetts.  It purchases gas  commodity for its customers  from a variety of
producers and suppliers to maintain reliable service at least cost. Commonwealth
Gas utilizes transmission pipeline capacity contracts,  primarily with Algonquin
Gas and Tennessee Gas pipelines,  to move the commodity from the various sources
to  Commonwealth  Gas'  natural  gas  receiving   stations  located   throughout
Commonwealth Gas' service territory. Natural gas received by Commonwealth Gas is
delivered into a fully integrated gas distribution  delivery system operated and
maintained by Commonwealth Gas. A centralized  system control center coordinates
daily  dispatch  of gas  supplies  into  and  around  the  distribution  system.
Commonwealth Gas additionally provides transportation on its distribution system
to customers who elect by choice to be served by commodity  suppliers other than
Commonwealth Gas.

     Commonwealth  Gas  currently is an  integrated  gas utility  company,  and,
following the Mergers,  will continue as such.  There will be no increase in the
size of Commonwealth Gas' gas utility operations as a result of the Mergers;  it
will simply be affiliated  with a larger  electric  utility system than it is at
present.

     There  will be "de  facto"  integration  of the gas  and  electric  utility
systems of NSTAR  following the Mergers  under the  standards  enunciated by the
Commission recently in TUC Holding Co.:

          Section  11(b)(1) makes provision for the acquisition and retention of
     more  than  one  integrated  system  only if the  requirements  of  section
     11(b)(1)(A)-(C)  ("ABC  clauses")  are  satisfied.  By its terms,  however,
     section  11(b)(1)  applies  only  to  registered  holding  companies.   The
     Commission has  previously  determined  that a holding  company may acquire
     utility  assets that will not when combined  with the  acquiring  company's
     existing  utility assets make up an integrated  system or comply fully with
     the ABC clauses,  provided that there is de facto integration of contiguous
     utility properties and the holding company will be exempt from registration
     under  section  3 of  the  Act  following  the  acquisition.  The  proposed
     acquisition meets these conditions for approval.

TUC Holding Co., HCAR No. 26749 at 305-06 (footnotes omitted).

     In TUC Holding Co.,  applying this standard to the  combination of a purely
electric  utility system with a purely gas utility system,  the Commission found
de facto integration of the combined utility systems:

          The  respective  service  territories  of the TUC and ENSERCH  systems
     generally  overlap.  The two systems will be coordinated  administratively.
     The combination  offers TUC and ENSERCH a means to compete more effectively
     in the emerging energy services  business,  and it does not appear that the
     merger will give rise to any of the abuses,  such as ownership of scattered
     utility  properties,  inefficient  operations,  lack of local management or
     evasion of state  regulation,  that section  11(b)(1) and the Act generally
     were intended to

                                       24

<PAGE>



     address.  The merger of the two  companies  should  have no effect upon the
     ability  of state  and  local  ratemaking  authorities  to carry  out their
     statutory  duties.  Accordingly,  the  Commission  does not  find  that the
     proposed  acquisition  would be  detrimental to the carrying out of section
     11, so that section 10(c)(1) of the Act is satisfied.

Id. at 306 (footnotes omitted).

     The combination of BEC Energy's  electric utility system with  COM/Energy's
combination gas and electric  utility systems clearly meets the standards for de
facto  integration  enunciated by the  Commission in TUC Holding Co. The service
territories of the gas and the electric  systems  overlap.  The electric and the
gas  systems  will  continue  to  be  coordinated   administratively,   and  the
consolidation  of those functions within a larger combined system is expected to
provide substantial  efficiencies and economies.  The Mergers will not give rise
to any of the  abuses,  such  as  ownership  of  scattered  utility  properties,
inefficient operations, lack of local management or evasion of state regulation.

     NSTAR's system following the Mergers will, in fact, be quite similar to the
combination exempt holding companies whose formation or expansion the Commission
has approved in the past under  Section  10.20/  Moreover,  NSTAR will remain an
exempt holding company and, once again, "exempt holding companies have generally
been  permitted  to retain or acquire  combination  systems so long as  combined
ownership of gas and electric operations is permitted by state law."21/

     The economies and  efficiencies  expected to accrue to NSTAR as a result of
the proposed  transaction  are  sufficient  to satisfy the  standards of Section
10(c)(2).22/

     The Commission has held that in order to demonstrate the required economies
and efficiencies it is permissible to:

     these are not precisely quantifiable.23/

NSTAR expects that there will be economies and  efficiencies  resulting from the
Mergers. See "Reasons for the Mergers", supra.

     It should be noted also that the Mergers are consistent  with Section 10(f)
of the Act,  which  states that the  Commission  may not approve an  acquisition
unless it appears to the Commission that such state laws as may apply in respect
of such  acquisition have been complied with.  Section 10(f),  unlike Section 8,
applies directly to exempt holding companies and involves the issue of complying
with all aspects of state  regulation  that apply to the  transaction,  not just
whether  or not state  regulators  have  adequate  regulatory  authority  over a
combination  system, and is satisfied in this case.24/ Indeed, it is a condition
to consummation of the Mergers that all applicable state laws and regulations be
complied with.

     C. Section 3(a)(1)

     Both BEC Energy and COM/Energy are currently  exempt from all provisions of
the Act except Section 9(a)(2) under Section 3(a)(1), BEC Energy by order of the
Commission and COM/Energy  pursuant to Rule 2. NSTAR seeks an order of exemption
pursuant  to Section  3(a)(1)  upon  completion  of the  proposed  transactions.
Section  3(a)(1) of the Act  authorizes  the  Commission  to exempt any  holding
company:

     if such holding company,  and every  subsidiary  company thereof which is a
     public-utility company from which such holding company derives, directly or
     indirectly,  any material part of its income, are predominantly  intrastate
     in character and carry on their businesses  substantially in a single State
     in which such holding company and every such subsidiary company thereof are
     organized.

     the  policy  of the Act is to  supplement,  not  supplant,  state and local
     regulation.

     Under Section 3(a)(1) of the Act, in order for a holding company to qualify
for an exemption,  each of its  "material"  subsidiaries  must be  predominantly
intrastate in nature and carry out their businesses  "substantially" in a single
state in which the holding company and each material subsidiary are organized.

     Following the Mergers,  NSTAR will have seven public utility  subsidiaries:
Boston Edison, Harbor Electric, Commonwealth Electric, Cambridge Electric, Canal
Electric,   Commonwealth  Gas  and  MATEP.  The  contribution  of  each  utility
subsidiary to NSTAR's  consolidated  utility revenues based on 1998 figures (pro
forma after adjustments related to sale of generating assets and the Mergers) is
shown below:

BEC Energy consolidated utility revenues (pre-Mergers)   $1,523
COM/Energy consolidated utility revenues (pre-Mergers)   $  836
NSTAR consolidated utility revenues (post-Mergers)       $2,359
Boston Edison utility revenues                           $1,518          64.3%

MATEP utility revenues                                   $   14           0.6%

     Following  the Mergers,  NSTAR will continue to be entitled to an exemption
pursuant to Section  3(a)(1)  because  each of its  material  subsidiaries  will
remain  predominantly  intrastate  in  character  and  carry  on its  operations
substantially within the Commonwealth of Massachusetts.  As set forth in greater
detail in  COM/Energy's  1998 Form  U-3A-2  filing,  a copy of which is attached

     the common stock of Connecticut Yankee Atomic Power Company. Canal Electric
     is  a  joint  owner,  together  with  several  other  New  England  utility
     companies,  of the  Seabrook  1 nuclear  power  plant  which is  located in
     Seabrook,  New  Hampshire.  Canal  Electric  has a 3.52%  interest  in this
     1,150,000 KW unit,  with an  entitlement of  approximately  40 MW of power.
     Canal  Electric owns a 2.5% equity  interest in the Vermont  Yankee nuclear

aggregate,  of less  than 1% of the total  assets  on the books of the  combined
enterprise.  Boston  Edison  makes  some  sales  of  electricity  at  wholesale,
virtually all of which occur either within Massachusetts or at the Massachusetts
border,  and are thus  intrastate in  character.  None of  COM/Energy's  utility
subsidiaries  sells gas or  electricity at wholesale  outside of  Massachusetts.
Thus  NSTAR,  following  the  Mergers,  will meet the  requirements  of  Section
3(a)(1).

Item 4. REGULATORY APPROVALS

     Set forth below is a summary of the  regulatory  approvals that the parties
have obtained or expect to obtain in connection with the proposed transaction.

     A. State Public Utility Regulation

     As a condition to the Mergers,  the utility  subsidiaries of BEC Energy and
COM/Energy  must file and must obtain the  approval of rate plans from the MDTE.
The MDTE has held several public hearings and has commenced a full investigation
of the rate  plans in  order  to  determine  their  propriety.  In  making  such
determination,  the MDTE may consider  such factors as the effect of the Mergers
on the rates  charged by BEC Energy's  and  COM/Energy's  subsidiaries,  service
quality issues, the financial integrity of the combined company,  and the effect
of the Mergers on competition,  economic  development  and employment.  Assuming
that the MDTE approves the rate plans,  following the Effective Time the utility
operations of NSTAR's utility  subsidiaries will remain subject to regulation by
the MDTE.

     A copy of the MDTE rate plan  application is attached hereto as Exhibit D-1
and a copy of the order  approving  the rate plans will be filed by amendment as
Exhibit D-2.

     B. Other Federal Regulations

                                       28

<PAGE>




     Federal  Power Act.  Section 203 of the  Federal  Power Act  provides  that
without first  receiving  authorization  from the FERC, no public  utility shall
sell  or  otherwise  dispose  of  its  jurisdictional  facilities;  directly  or
indirectly,  merge or consolidate its facilities with those of any other person;
or acquire any security of any other public  utility.  BEC Energy and COM/Energy
thus  require  FERC  approval  to  combine  their  businesses  by  merging  into
acquisition  subsidiaries of a new holding company,  NSTAR. Under Section 203 of
the Federal  Power Act,  the FERC must  approve the Mergers if it finds that the
Mergers are consistent with the public interest.  The FERC indicated in a recent
policy  statement  that it will evaluate the  following  criteria in analyzing a
merger under Section 203:

     (1) The FERC will  examine  the  effect of the  merger  on  competition  in
electric  power  markets,  using an  approach  derived  from the  Department  of
Justice/Federal Trade Commission Horizontal Merger Guidelines.  It will use this
approach to  determine s whether the merger will result in an undue  increase in
market concentration or in the s market power of the applicants.

     (2) The FERC will  review  the  effect of the  merger on state and  federal
regulation of the applicants.

     BEC Energy and COM/Energy have filed a combined  application  with the FERC
requesting  that it approve the Mergers  under  Section 203 of the Federal Power
Act.

     Antitrust  Considerations.   Under  the  HSR  Act  and  related  rules  and
regulations,  BEC Energy and  COM/Energy may not complete the Mergers until they
have satisfied the HSR Act reporting and waiting requirements. Each Company must
first file notification and report forms with the Antitrust  Division of the DOJ
and the FTC and then wait as its case is reviewed. The HSR Act waiting period is
30 days from the date both  parties file their report forms unless the period is
terminated  before 30 days have passed or  extended  by an FTC or DOJ  Antitrust
Division  request for  additional  information.  The HSR Act waiting  period was
terminated  on May 7, 1999.  If the Mergers are not  completed  within 12 months
after the  expiration  or earlier  termination  of the HSR waiting  period,  BEC
Energy  and  COM/Energy  would be  required  to submit  new  filings  to the DOJ
Antitrust Division and the FTC. In that case, a new HSR Act waiting period would
have to expire or earlier terminate before the Mergers could close.

     Atomic Energy Act. Both Boston Edison  Company's  Pilgrim nuclear  facility
and the Seabrook nuclear facility, a nuclear power plant in which COM/Energy has
a 3.52% ownership  interest,  are subject to the regulatory  jurisdiction of the
Nuclear Regulatory  Commission  ("NRC").  The Atomic Energy Act of 1954 provides
that ownership interests in nuclear plants may not be transferred or disposed of
through a  transfer  of  control  unless  the NRC  finds  that the  transfer  is
consistent  with  the  Atomic  Energy  Act  and  consents  to the  transfer.  In
accordance  with the Atomic  Energy  Act,  BEC Energy and  COM/Energy  will seek
approval from the Nuclear Regulatory Commission as necessary.

     Re:  D.T.E.  99-19,  Request for  Approval  of Rate Plan for Boston  Edison
          Company,  Cambridge  Electric  Light  Company,  Commonwealth  Electric
          Company and Commonwealth Gas Company

Dear Secretary Cottrell:

     Enclosed  for  filing is a $100  filing  fee and an  original  and nine (9)
copies of the  Joint  Petition  of  Boston  Edison  Company  ("Boston  Edison"),
Cambridge Electric Light Company  ("Cambridge"),  Commonwealth  Electric Company
("Commonwealth  Electric") and  Commonwealth  Gas Company  ("Commonwealth  Gas")
(together,  the "Joint Petitioners") for Approval of Rate Plan by the Department
of  Telecommunications  and Energy (the "Department")  pursuant G.L. c. 164, ss.
94.  The  Rate  Plan is filed  in  conjunction  with  the  merger  of the  Joint
Petitioners'  parent  companies,  BEC  Energy  and  Commonwealth  Energy  System
("COM/Energy").  Also enclosed is a Motion for Protective  Treatment for certain
confidential  materials included in the filing. The original filing and one copy
include  the  materials  for  which  the  Joint  Petitioners  request  protected
treatment.  The  confidential  information  has been redacted from the remaining
eight copies.

     The Joint  Petitioners  believe  that  this  merger  will  provide a unique
opportunity  for the four companies to reduce costs while  improving  service to
customers.  The proposed Rate Plan is intended to permit the consummation of the
merger in a way that will provide  long-term value for customers,  employees and
shareholders.  The  consolidation  and  integration of utility  operations  will
create  economies  of scale and  synergies  that  will  lower  costs,  diversify
operations and improve the financial strength of the individual companies.  This
will lead to improved  efficiency,  lower-cost  operations,  better  service for
utility  customers,  and  opportunities  for  employees  in a  more  diversified
company. Although the Rate Plan provides shareholders the opportunity to recover
the up-front costs needed to achieve these customer benefits,  the magnitude and
permanence of the customer  benefits will produce a value for customers that far
outweighs the associated  costs. The Joint Petitioners seek approval of the Rate
Plan as consistent with the public interest  pursuant to G.L. c. 164, ss. 94 and
Department  precedent.  See NIPSCO-Bay State  Acquisition,  D.T.E. 98-31 (1998);
Eastern-Essex Acquisition, D.T.E. 98-27 (1998); Mergers and Acquisitions, D.P.U.
93-167-A (1994).

     In the filing, the Joint Petitioners present the following testimony:

      Thomas J. May,  President  and Chief  Executive  Officer of BEC Energy and
     Boston Edison,  provides a description  of BEC Energy's  decision to pursue
     this  merger and an overview  of how the Rate Plan is  consistent  with the
     Department's regulatory objectives and policies.

      Russell D.  Wright,  Chief  Executive  Officer of  COM/Energy,  Cambridge,
     Commonwealth  Electric and  Commonwealth  Gas,  provides a  description  of
     COM/Energy's  decision  to pursue  this  merger,  explains  how the  merger
     benefits  customers  and  describes  various  elements  of the  Rate  Plan,
     including  the  four-year  rate freeze,  the  allocation  of net savings to
     customers and the service-quality plan for Cambridge, Commonwealth Electric
     and Commonwealth Gas.

      James J. Judge,  Senior Vice  President  and  Treasurer of Boston  Edison,
     describes the merger  transaction,  describes  various elements of the Rate
     Plan, including the recovery of merger-related cost and the service-quality
     plan for Boston Edison, and explains how approval of the proposed Rate Plan
     is  consistent  with the  public  interest  and  complies  with  Department
     precedent.

      Thomas J. Flaherty,  National Partner - Energy Consulting and a partner in
     the Deloitte & Touche Consulting  Group, LLC,  describes and quantifies the
     projected  cost savings  that have been  identified  as resulting  from the
     merger and compares those cost savings with other recent transactions.

      John Scott  Magrane,  Jr.,  Vice  President  in the Energy and Power Group
     (Investment  Banking  Division)  of  Goldman  Sachs  &  Co.,  who  provides
     financial  advisory  services to BEC Energy,  reviews the recent history of
     mergers in the  utility  industry  and  discusses  the manner in which this
     transaction fits into that framework.

     As described in the Joint Petition, Boston Edison, Cambridge,  Commonwealth
Electric and Commonwealth Gas respectfully request that the Department:

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

      Confirm that  no  transfer  of the  franchise  rights  of  Boston  Edison,
     Cambridge,  Commonwealth  Electric or Commonwealth Gas will result from the
     merger  and  related  transactions,  and  therefore,  no  approval  by  the
     Massachusetts General Court is required under G.L. c. 164, ss. 21.


     Thank you for your attention to this matter.

                                                     Very truly yours,

                                                     /s/ Robert J. Keegan

                                                     Robert J. Keegan

   JOINT PETITION OF BOSTON EDISON COMPANY, CAMBRIDGE ELECTRIC LIGHT COMPANY,
           COMMONWEALTH ELECTRIC COMPANY AND COMMONWEALTH GAS COMPANY
                            FOR APPROVAL OF RATE PLAN

     Now come Boston Edison Company ("Boston Edison"),  Cambridge Electric Light
Company ("Cambridge"),  Commonwealth Electric Company ("Commonwealth  Electric")
and  Commonwealth  Gas  Company  ("Commonwealth  Gas")  (together,   the  "Joint
Petitioners"),  and respectfully move that the Department of  Telecommunications
and Energy (the "Department") approve the Joint Petitioners' Rate Plan, pursuant
to G.L. c. 164,  ss. 94. In  addition,  the Joint  Petitioners  request that the
Department  determine that no transfer of the franchise rights of Boston Edison,
Cambridge, Commonwealth Electric or Commonwealth Gas will result from the merger
and related  transactions,  and  therefore,  no  approval  by the  Massachusetts
General Court is required under G.L. c. 164, ss. 21.

     In support thereof, the Joint Petitioners state the following:

1.   Boston Edison is a Massachusetts  electric company providing retail service
     in  Massachusetts,  and is subject to the  regulatory  jurisdiction  of the
     Department pursuant to G.L. c. 164, ss. 1.

2.   Cambridge and Commonwealth  Electric are Massachusetts  electric  companies
     providing  retail  service  in  Massachusetts,   and  are  subject  to  the
     regulatory jurisdiction of the Department pursuant to G.L. c. 164, ss. 1.

3.   Commonwealth Gas is a Massachusetts gas company providing retail service in
     Massachusetts,  and  is  subject  to  the  regulatory  jurisdiction  of the
     Department pursuant to G.L. c. 164, ss. 1.

4.   BEC Energy is a Massachusetts business trust established and existing under
     a  Declaration  of Trust dated March 25,  1997,  with a principal  place of
     business  in  Boston,  Massachusetts.  Boston  Edison  is  a  wholly  owned
     subsidiary of BEC Energy.

5.   Commonwealth Energy System ("COM/Energy") is a Massachusetts business trust
     organized under a Declaration of Trust dated December 31, 1926, as amended,
     with a principal place of business in Cambridge, Massachusetts.  Cambridge,
     Commonwealth Electric and Commonwealth Gas are wholly owned subsidiaries of
     COM/Energy.

6.   On December 5, 1998,  BEC Energy and  COM/Energy  entered into an Agreement
     and Plan of Merger (the "Merger Agreement"),  which is subject to necessary
     approvals of government regulatory agencies having jurisdiction,  providing
     for a merger  transaction  among the  companies.  As a result of the Merger
     Agreement,  the stock of BEC Energy and  COM/Energy  will be exchanged  for
     shares in BEC NEWCo, Inc. ("NEWCo"), a new Massachusetts holding company.

7.   The Merger Agreement is subject to expiration of the waiting period and the
     review of the United States Federal Trade  Commission and the United States
     Department  of  Justice   pursuant  to  the   Hart-Scott-Rodino   Antitrust
     Improvement Act of 1976, as amended.  In addition,  the Merger Agreement is
     subject to the approval of the Federal Energy  Regulatory  Commission  (the
     "FERC")  pursuant to the Federal  Power Act, as amended,  approvals  of and
     filings  with  the  Securities  and  Exchange  Commission  pursuant  to the
     Securities and Exchange Act of 1934 and the Public Utility  Holding Company
     Act of 1935, as amended, and the Nuclear Regulatory  Commission pursuant to
     Section 184 of the Atomic  Energy Act of 1954,  as  amended,  and 10 C.F.R.
     50.80.  Department  approval of the Merger  Agreement is not required since
     the merger is not between electric or gas companies,  which would otherwise
     be subject to Department  approval in accordance  with G.L. c. 164,ss.  96.
     However, the Rate Plan for Cambridge,  Commonwealth Electric,  Commonwealth
     Gas and Boston  Edison is subject to the  Department's  review and approval
     pursuant to G.L. c. 164,ss. 94.

8.   The  Rate  Plan  is  fully   described  in  the  testimony  and  supporting
     documentation filed by five witness: Thomas J. May, Chairman, President and
     Chief Executive  Officer of BEC Energy (Exhibit TJM-1);  Russell D. Wright,
     Chief  Executive  Officer of COM/Energy  (Exhibit  RDW-1);  James J. Judge,
     Senior Vice  President  and  Treasurer of Boston  Edison  (Exhibit  JJJ-1);
     Thomas J. Flaherty, National Partner - Energy Consulting and partner in the
     Deloitte & Touche Consulting Group LLC (Exhibit TJF-1) and John S. Magrane,
     Jr., Vice President of Goldman, Sachs & Co. (Exhibit JSM-1).

9.   The Rate Plan provides for: (1) a four-year  distribution rate freeze;  (2)
     the   recovery  of   merger-related   costs  over  40  years;   and  (3)  a
     service-quality  plan that will ensure that there will be no degradation in
     the service  quality  provided to retail  customers  of  regulated  utility
     service.

10.  The Rate Plan will provide  customers  with  significant  price  stability,
     savings through the avoidance of likely increases in base rates,  continued
     and improved quality of service and long-term rates that will be lower than
     those that would  otherwise  have to be paid by customers in the absence of
     the merger.  The Rate Plan also  includes the approval of a structure  that
     will afford shareholders a reasonable opportunity to recover merger-related
     costs.

11.  As discussed by Mr. Judge,  the Rate Plan affects only the  non-reconciling
     base rates under the jurisdiction of the Department. Accordingly, the rates
     for the three electric  companies that reflect  transition costs (including
     mitigation),  transmission  services regulated by the FERC,  standard offer
     service and default service  charges,  are not covered by the Rate Plan and
     will not be affected by the rate freeze.  Similarly for  Commonwealth  Gas,
     reconciling rate elements, like the cost of gas adjustment clause and local
     distribution adjustment clause, are not included in the Rate Plan.

WHEREFORE, the Joint Petitioners respectfully request that the Department:

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

     b.   Confirm  that no transfer of the  franchise  rights of Boston  Edison,
          Cambridge,  Commonwealth Electric or Commonwealth Gas will result from
          the merger and related transactions, and therefore, no approval by the
          Massachusetts General Court is required under G.L. c. 164, ss. 21.

     c.   Issue such other and further orders as may be necessary.

                                      Respectfully submitted,
                                      JOINT PETITIONERS:

                       APPLICATION FOR APPROVAL OF MERGER

     Commonwealth  Energy System ("CES") and BEC Energy  ("BEC")  (collectively,
"the Applicants"),  on behalf of BEC's affiliate Boston Edison Company ("BECO"),
CES' affiliates Canal Electric Company ("Canal"),  Commonwealth Electric Company
("Commonwealth"),  Cambridge  Electric Light Company  ("Cambridge"),  COM/Energy
Marketing,  Inc. ("CEM"),  and Medical Area Total Energy Plant, Inc.  ("MATEP"),
hereby file this Application requesting any and all authorizations  necessary to
effectuate  the approval of the merger of CES and BEC pursuant to Section 203 of
the Federal Power Act ("FPA"). As demonstrated below, the proposed merger easily
satisfies the standards set forth in the Commission's  Merger Policy  Statement1
and should therefore be approved as "consistent with the public interest."

I.   SUMMARY AND REQUEST FOR EXPEDITED  APPROVAL AS  CONTEMPLATED  BY THE MERGER
     POLICY STATEMENT

     The proposed merger is between two holding  companies -- CES and BEC. CES's
utility  subsidiaries  are engaged in both natural gas and electric  businesses;
BEC's utility subsidiaries are engaged in the electric business.  As a result of
the merger, the Applicants' FPA-jurisdictional

     1 Inquiry Concerning the Commission's Merger Policy Under the Federal Power
Act: Policy  Statement,  Order No. 592, III FERC Stats. & Regs. P. 31,044 (1996)
(codified at 18 C.F.R. ss. 2.26) ("Merger Policy Statement").

                                        1

<PAGE>



affiliates  will  become  wholly-owned  subsidiaries  of a new  holding  company
(currently named BEC Newco, Inc. ("BEC Newco")).

     The merger  satisfies  the standards in the Merger  Policy  Statement.  The
     proposed merger:

     o    will not create undue market  power or  concentration  in any relevant
          market, based on a competitive screen analysis and other factors;

     o    will not adversely affect any wholesale rate; and

     o    will not impair the  Commission's  regulation or the regulation of any
          state Commission.

     The merger  occurs within the context of the  restructuring  of the BEC and
CES  regulated   subsidiaries   pursuant  to  state  competitive  plans.2  These
subsidiaries have already committed their  transmission  facilities to operation
and control by ISO-New  England,  Inc.  ("ISO-New  England"),  and have  already
divested  themselves  of  most  of  their  generating  capacity.  The  regulated
subsidiaries  have sold the vast majority of their owned  generating  resources,
are engaged in selling the remaining generation, will attempt to sell or buy out
of their  purchased  power  agreements  ("PPAs") and intend to withdraw from the
generation  business.  They  will  remain in the power  sales  business  only as
necessary  to serve  "standard  offer" and  "default  service"  customers to the
extent required by the Massachusetts Department of Telecommunications and Energy
("Massachusetts   DTE"),   formerly  the  Massachusetts   Department  of  Public
Utilities,  and to serve requirements customers for the remaining terms of their
contracts.  In short, the BEC and CES regulated  subsidiaries will become,  over
time,  essentially wires companies  enabling the ultimate  consumers residing in
their distribution service areas to choose their power supplier.

- --------
     2 The  term  "regulated  subsidiaries"  refers  to the  three  BEC  and CES
electric  subsidiaries who serve retail load - Boston Edison Company,  Cambridge
Electric Light Company, and Commonwealth Electric Company; and to Canal Electric
Company,  a public  utility  engaged in the purchase and sale of  electricity at
wholesale.

     The market  concentration  analysis,  submitted herewith in accordance with
Appendix A of the Merger Policy  Statement,  demonstrates that the consolidation
of the remaining  generating capacity temporarily still owned by the BEC and CES
regulated subsidiaries produces no material increase in market concentration and
does  not in any  other  way  have  any  adverse  affects  on  competition.  The
Applicants'  submission shows that wholesale customers,  most of whom are served
under recently  renegotiated fixed rate contracts,  will be "held harmless" from
merger- related costs that exceed merger-related savings.

     Finally,  the merger will not reduce the  effectiveness of regulation.  The
Commission's regulatory authority over the BEC and CES public utility affiliates
will be the same after the merger.  The  Applicants  include  with this filing a
commitment  (the "Ohio  Power"  waiver) in wholesale  ratemaking  to follow this
Commission's  policies for inter-affiliate  non-power  transactions.  The merger
requires  approval of the  Massachusetts  DTE.  Thus,  the merger of CES and BEC
satisfies the standards reflected in the Merger Policy Statement.

     In the Merger  Policy  Statement,  the  Commission  has  committed to swift
action in cases,  such as this, which do not present  substantive  issues:

          if a  merger  falls  below  the HHI  screen,  the  applicants  propose
          adequate ratepayer protection mechanisms,  and the applicants make the
          commitments  necessary  to assuage  our  concerns  about the effect on
          regulation, we should be able to act much more quickly.3

The Applicants  respectfully submit that their proposed merger plainly meets all
of the Commission's  requirements for regulatory  approval and for granting that
approval on the expedited basis contemplated in the Merger Policy Statement.

II. JURISDICTIONAL STATEMENT

     This  Application is being submitted  because the Commission has determined
that it has  jurisdiction  over the  merger of  holding  companies  with  public
utility  subsidiaries  unless the holding  companies  can  overcome a rebuttable
presumption  that an indirect  merger of the  jurisdictional  facilities  of the
public utility  subsidiaries  occurs when the holding companies merge.  Illinois
Power Co., 67 FERC P. 61,136 (1994)  ("Illinois  Power").4 The Applicants do not
contest the  Commission's  jurisdiction  over the proposed  merger and therefore
submit this  Application,  notwithstanding  the fact that the  facilities of the
public utility subsidiaries will not be consolidated or merged at this time.5

III. APPLICANTS

     BEC is a Massachusetts  business trust and an exempt public utility holding
company under the Public Utility  Holding  Company Act of 1935  ("PUHCA").6  BEC
owns all of the  outstanding  common  stock of BECO,  which is a public  utility
under Section 201(e) of the FPA providing  retail  electric  service  chiefly in
metropolitan  Boston, an area of about 590 square miles encompassing the City of
Boston and 39 surrounding  cities and towns.  BECO's  distribution  service area
includes some 663,000 retail customers.  BECO also provides  wholesale  services
that are subject to this Commission's jurisdiction.

     CES is also a  Massachusetts  business  trust and an exempt public  utility
holding company

- --------
     4 In approving  the  formation of BEC,  the  Commission  noted its Illinois
Power  determination  and ordered BEC to file an application  for approval under
Section 203 if it merged with another holding company owning public utilities or
to overcome the rebuttable presumption. Boston Edison Co., 80 FERC P. 61,274, at
61,994-5 (Ordering Paragraph (F6)) (1997).

     5 If the facilities of the public utility  subsidiaries  are proposed to be
combined at a later time, an appropriate  application would be submitted for the
Commission's approval.

     6 As amended, 15 U.S.C. ss. 79b(a)(1).

<PAGE>



under PUHCA.  CES owns all the common stock of three  regulated  public  utility
companies  Commonwealth,  Cambridge,  and Canal.  Commonwealth  provides  retail
service to approximately 327,000 retail customers in Southeastern Massachusetts,
including Cape Cod and Martha's  Vineyard,  and also provides FPA jurisdictional
services. Cambridge provides retail service to some 45,900 customers in the City
of  Cambridge,  Massachusetts,  and also provides FPA  jurisdictional  services,
including  partial  requirements  service  to the Town of  Belmont  ("Belmont"),
Massachusetts.  Canal, a wholesale  electric  generating  company with no retail
customers, owns a 3.52% share of the Seabrook 1 nuclear power plant.

     CES also owns CEM, a power  marketing  subsidiary  which  owns no  physical
facilities for electric generation or transmission, and Advanced Energy Systems,
Inc.  ("AES")  which is the  owner of  MATEP.  MATEP  owns a 62 MW  cogeneration
facility that sells electricity,  steam and chilled water to its affiliate MATEP
LLC which,  in turn,  sells energy to specific retail  customers  including five
Boston area hospitals and the Harvard Medical School and its affiliated  schools
under  long-term  contracts that do not expire until 2021. CES also owns two gas
companies:  (1)  Commonwealth  Gas Company  ("Commonwealth  Gas") which provides
local gas distribution service to approximately  239,000 retail customers in the
Cities of Cambridge and Somerville in Middlesex  County,  a small portion of the
City of Boston in Suffolk  County,  and in various other  eastern  Massachusetts
municipalities;  and (2) Hopkinton LNG Corp.,  an entity which owns and operates
two liquefied natural gas ("LNG") facilities.7

IV. DESCRIPTION OF THE MERGER

     The merger is between CES and BEC. Under the terms of the merger agreement,
a new holding company  currently named BEC Newco,  Inc. will be created and both
BEC and CES will exchange  their shares for a combination  of stock in BEC Newco
and cash.  The  parties  anticipate  that at the close of the  transaction,  BEC
stockholders  will own  approximately 68% of BEC Newco and CES stockholders will
own  approximately  32%.  BEC Newco  will be an exempt  public  utility  holding
company and the parent of all existing BEC and CES subsidiaries. (When BEC Newco
and its subsidiaries are referred to in the aggregate, they are described herein
as the  "Combined  Companies").  There are no  immediate  plans to merge the BEC
Newco  subsidiaries,  each of  which  will  maintain  its  individual  corporate
existence in the initial period following the merger. Article I of the Agreement
and Plan of Merger ("the Merger Agreement") describes the transactions that will
be utilized to effectuate the merger.  The Merger  Agreement is included in this
filing in Exhibit H.

V. MERGER ANALYSIS

     In the Merger Policy  Statement,  the  Commission  reviewed and revised its
policy for  determining  whether a merger is consistent with the public interest
standard of Section 203 of the FPA. The  Commission  concluded that its analysis
would focus on three factors:

     o    The effect of the merger on competition, using a competitive screen to
          determine whether the merger would increase horizontal market power in
          a relevant market;

     o    The effect of the merger on  ratepayers,  focusing on the measures the
          applicants propose to protect ratepayers from merger-related harm;

     o    The effect of the merger on regulation, focusing on any possible shift
          of regulatory authority.8

     A.   The Transaction  Will Not Create or Increase Undue Market Power in Any
          Market

     The proposed  merger will not create or enhance  market power in any market
under the  standards  employed by the  Commission  or,  indeed,  under any other
rational  means of examining  market power.  To establish  this,  the Applicants
asked an independent  expert,  Mr. John J. Reed, to perform an Appendix A screen
analysis,  as required by the Merger Policy  Statement,  to test for  horizontal
market power impacts,  and asked him to evaluate any other potential  impacts of
the  merger on  competition.  Mr.  Reed  concludes  from his  horizontal  market
analysis  that the  changes in HHI  values  resulting  from the  merger  will be
minimal as to concentration of control over generating  resources.  He found HHI
increases far below the safe-harbor  thresholds established by the Merger Policy
Statement.  Even those  insignificant  changes in market  concentrations will be
further  diminished  as Applicants  continue to implement  their plans to divest
themselves of their remaining generation interests and PPAs. Mr. Reed also shows
that CES' affiliated  natural gas assets cannot be used to restrict gas supplies
to generators in competition with the Applicants'  generating companies and that
there are no other  impacts of the merger that could reduce  competition  in the
electric generation market.

          1.   ISO-New  England  Eliminates  Transmission  Market  Power  in New
               England

     The BEC and CES regulated subsidiaries are members of the New England Power
Pool ("NEPOOL") and have committed their pool transmission facilities ("PTF") to
the operational  control of ISO-New  England.  The ISO-New  England's  principal
responsibilities  include  administration of the NEPOOL open access transmission
tariff ("NEPOOL Tariff"),  the operational control of the New England bulk power
system, protection of NEPOOL system

                                       -7-

<PAGE>



reliability, and oversight of the New England Power Exchange.9 The NEPOOL Tariff
provides for  postage-stamp  rates which  eliminate  pancaking  of  transmission
charges in New England thereby  creating a single power market that  encompasses
virtually the entire New England region.

          2.   Transmission Tariff

     As noted above,  regional  transmission  service in New England is provided
over PTF under the NEPOOL Tariff,  which is administered by ISO-New England. The
chief  services are "RNS" or regional  network  service  provided  under the RNS
rates  and  regional   point-to-point   service   provided  under  the  regional
point-to-point  rates.  The NEPOOL Tariff is complemented by local  transmission
services  provided  by  the  individual   transmission-owning   NEPOOL  members,
including BECO,  Cambridge,  and Commonwealth,  under their respective Order No.
888 tariffs.  Local service is provided under individual utility "LNS" rates and
local  point-to-point  rates.  These local rates  include  temporary  transition
charges and local facility charges.

     ISO-New    England   also   has    planning    and    congestion-management
responsibilities  and maintains a market monitoring  function to protect against
anti-competitive  practices  by the owners of the  region's  generating  assets.
ISO-New England is complemented  by the  restructured  NEPOOL whose objective is
also to foster competition within the New England region,  promote attainment of
the maximum possible economy of service,  and protect system reliability.  These
arrangements create a competitive power supply market that brings together power
suppliers and

and the  transfer of  operational  control of the NEPOOL grid to that entity was

electricity   consumers  in  the  New  England  region.   The  effect  of  those
arrangements is to create a power supply market that  encompasses the entire New
England region, and which eliminates transmission market power through operation
of the ISO.

          3.   Applicants'  Affiliates  Have  Divested  Virtually  All of  Their
               Generation  Facilities  and  are  Divesting  Their  Power  Supply
               Portfolios

     BEC and CES are in the process of converting  their regulated  subsidiaries
from vertically integrated operations by withdrawing those subsidiaries from the
business  of  power  generation  and  by  concentrating   their  public  utility
activities in the transmission and distribution  business.  This conversion will
enable the Combined Companies' distribution customers to purchase power directly
from the suppliers of their choice.

     Consistent  with the withdrawal of their  regulated  subsidiaries  from the
power generation business, BECO, Cambridge, and Commonwealth will be relieved of
their duty to provide  generation  service to the retail  consumers  residing in
their distribution  service areas. On March 1, 1998, all retail customers became
free to purchase power  directly from the power  generation  market.  As further
described in the Testimony of Geoffrey O. Lubbock, appended hereto as Attachment
1 (the "Lubbock  Testimony"),  BECO, Cambridge and Commonwealth will continue to
provide  service only to pre-March 1, 1998  customers  who elect not to choose a
supplier,  low-income  customers  unable to obtain  service  from a  competitive
supplier, and retail customers temporarily between suppliers.10

     BECO had owned 1,657 MW of fossil and nuclear generating  capacity.  On May
15, 1998 as part of the restructuring  process,  BECO sold to Sithe Energies the
entirety of its fossil

<PAGE>



generation plants,  representing about 8% of the regional  generating  capacity.
The divested plants are described in more detail in Section VII below.11

     On November 18, 1998,  BECO entered into a purchase and sale agreement with
Entergy Nuclear Generation Company ("Entergy Nuclear"),  a subsidiary of Entergy
Corporation, for Entergy Nuclear to purchase BECO's 670 MW Pilgrim nuclear power
plant. The sale was a result of a competitive bid process which included opening
solicitations to approximately 175 potential purchasers.  Filings were made with
the  Massachusetts DTE on December 3, 1998, and with this Commission on December
24, 1998 (Docket Nos. EC99-18-000,  et al.) for approval of this transaction. If
the requisite approvals for this sale are not obtained,  it is likely that BECO,
in the near future, would shut down the Pilgrim plant and permanently retire it.

     BECO also has several  PPAs,  chiefly with  non-utility  generators,  under
which in the aggregate BECO purchases 828 MW of capacity.12  BECO's intent is to
sell or buy out of those  contracts.  When the Pilgrim unit is sold or shut down
and when BECO has  divested  itself of its PPAs,  it will no longer  own or have
contracts in any generating assets.

     As discussed in the Testimony of Michael R.  Kirkwood,  appended  hereto as
Attachment 2 (the "Kirkwood  Testimony"),  the CES regulated  subsidiaries  have
also sold most of their owned- generation plant to Southern Energy Canal, L.L.C.
("Southern  Canal") and Southern Energy Kendall,  L.L.C.  ("Southern  Kendall"),
subsidiaries of The Southern Company.13 The parties

consummated  the  transaction  on December 30,  1998.14 The  divested  units are
described in Section VII. These companies'  remaining owned generating  capacity
consists of Cambridge's 13.5 MW Blackstone facility and Canal's 40.5 MW interest
in the Seabrook nuclear power plant.  Cambridge and Canal are engaged in efforts
to sell that  generating  capacity.  In addition,  like BECO,  the CES regulated
subsidiaries  will  also  seek  to sell or buy out of  their  PPAs.  When  those
transactions are complete,  none of CES' regulated subsidiaries will own or have
rights in any generating capacity.

          4.   The Proposed Merger Does Not Increase Horizontal Market Power

     The  Commission  has  adopted  the  Department  of  Justice/Federal   Trade
Commission  Merger  Guidelines  ("Guidelines")  as the  framework  for analyzing
impact on  competition,15  and it  applies  an  analytic  "screen"  based on the
Guidelines.  See Appendix A of the Merger Policy Statement (P. 31,044 at 30,128,
et seq.).  As  discussed  above,  Mr. John J. Reed has  performed  an Appendix A
analysis  to test  the  impact  of the  merger  on  competition.  Mr.  Reed  has
summarized his analysis in Testimony  appended hereto as Attachment 3 (the "Reed
Testimony"). The analysis itself appears as Volume II of this filing.16 Based on
that analysis, Mr. Reed concludes that the merger does not pose any market power
concerns.

     Following the principals of the Merger Policy Statement, Mr. Reed used four

measures - economic capacity, available economic capacity,  uncommitted capacity
and total  capacity - to test the  competitive  impacts of the  merger.  He also
evaluated the effects of the market  restructuring in New England,  particularly
the adoption of a regional open-access transmission tariff with regional postage
stamp rates,  and the creation of ISO-New  England to administer that tariff and
to assume other  responsibilities  for coordinating the New England grid and the
regional  power supply  markets.  He concluded that those  initiatives  have the
effect of enabling  consumers to purchase  electricity  from  suppliers  located
throughout  New  England  and had  resulted  in the  establishment  of a  single
destination  market consisting of the entire New England region.  His conclusion
in that  regard is  consistent  with  determinations  made by the  Commission.17
Potential  suppliers to this regional market consist of producers located in New
England and in the adjacent  areas of New York,  New  Brunswick and Quebec which
have traditionally served as a source of power for New England utilities.

     Mr. Reed found that BECO has no uncommitted capacity. Therefore, the merger
cannot increase  market power as measured by that benchmark.  He also found BECO
has no available economic capacity. Therefore, the merger cannot increase market
power as measured by that benchmark.

     Mr. Reed's total capacity  analysis,  performed for the summer,  winter and
shoulder  peak  periods,  also  demonstrates  that  the  merger  was  devoid  of
anti-competitive  effects. He found that the market was moderately concentrated.
In that moderately  concentrated market, the highest HHI increase resulting from
the merger is 28 in the winter period. Those increases are well within

safe harbor levels,  and show that the merger cannot possibly have the effect of
reducing competition.

     Mr. Reed's economic  capacity  analysis,  performed for seven time periods,
also showed that the merger has no adverse impact on competition. This market is
also  moderately  concentrated  with  post-merger  HHIs  well  under  the  1,800
demarcation  line  between  heavily  concentrated  and  moderately  concentrated
markets.  The largest HHI change,  47, occurred in the shoulder off-peak period.
The remaining HHI  increases  were within the range of 27 to 38. Those  results,
which are summarized in the following table,  show  conclusively that the merger
of BEC and CES does not have the effect of reducing competition.

     Even  those  insignificant  increases  in  market  concentration  seriously
overstate  the  competitive  effects of this merger due to the steps,  described
above, that the merging companies' jurisdictional  subsidiaries continue to take
to divest the relatively  small  remainder of their  directly  owned  generating
plant and their  PPAs.  As those  additional  divestitures  are  completed,  the
competitive effects of the merger will progressively reduce to zero or to nearly
zero.  Moreover,  because the Combined  Company cannot exercise control over its
power  purchases to withhold that capacity from the market,  even in the interim
period following consummation of the merger and prior to the completion of those
planned divestitures, the merger can have virtually no market power impacts.

                                      -13-

<PAGE>



     In summary, Mr. Reed's finding is that the merger of BEC and CES has a zero
or de  minimis  impact  on  market  concentration  in the  markets  he  studied.
Eventually,  even the de minimis impact will be reduced to virtually zero as the
Combined Company's subsidiaries further implement their divestiture plans.

          5.   The Merger Does Not Raise Vertical Market Power Issues

     In Enron Corp. and Portland  General Corp.,  the Commission  noted that the
merger of a company owning  pipeline  facilities  with a company owning electric
generation  assets  could raise  vertical  market  power  issues if the pipeline
assets  could  be  used  to  restrict  gas  supplies  to  a  competing  electric
generator.18 The Commission found in Enron that the pipeline assets could not be
used to restrict gas because the pipeline assets were operated on an open-access
basis and because there were  competing  pipelines  with excess  capacity to the
same markets.

     As  described in Mr.  Reed's  Testimony  and the Reed Report,  the proposed
merger would not increase the BEC and CES regulated subsidiaries' opportunity to
exercise vertical market power by interfering with the competitiveness of either
(i) the existing entities  participating in the market; or (ii) any new entities
seeking  to  enter  and  compete  in the  market.  The  BEC  and  CES  regulated
subsidiaries  cannot  create  barriers  to entry for  existing  or new  electric
generation since:

     o    they do not  control  access  to  suitable  sites  for new  generation
          development;

     o    they do not control key inputs for electric generation,  i.e., natural
          gas supplies or electric generation  equipment  supplies,  which could
          impact the competitiveness of the market;

     o    they do not  control  the  transportation  of key inputs for  electric
          generation which could impact the competitiveness of the market, i.e.,
          natural gas pipeline transportation assets; and

<PAGE>



     o    they supply only a de minimis  amount of natural gas to the downstream
          electric generation market.

     For these  reasons,  as further  described  in  Attachment  3 and Volume II
hereto, the merger does not raise any vertical market power issues.

          6.   Conclusion Regarding the Effect of the Merger on Competition

     For all the  foregoing  reasons,  the merger is virtually  devoid of market
power  issues and easily  passes the  competitive  screen  adopted in the Merger
Policy  Statement.  This analysis shows that the merger would not  significantly
increase  the HHIs or any other  index of  market  power and will only have a de
minimis effect in NEPOOL. There are no other factors which would tend to enhance
market power, either through control of natural gas facilities or otherwise.  In
sum, it is simply not  possible  for the  proposed  merger to have any  negative
effect upon  competition,  nor are there any  reasonably  disputable  facts that
would warrant  setting these issues for hearing.  For these reasons,  as further
described in  Attachment  3 and Volume II hereto,  the merger does not raise any
vertical market power status.

     B.   The Merger Will Not Adversely Affect Rates

     In the Merger Policy Statement,  the Commission made clear that its concern
with the effect of a proposed merger on rates is to protect ratepayers from rate
increases  caused by the merger.19  This concern is focused on the ratepayers of
public  utilities  whose rates are  premised on costs since,  as the  Commission
ruled in Enron,  there are no  rate-related  concerns  with respect to entities,
such  as  power  marketers,  which  make  sales  only  under  market-based  rate
schedules.20

     The  Applicants  commit,  as a condition  for approval of the merger,  that
their  firm  wholesale  requirements  and  transmission  customers  will be held
harmless from  merger-related  cost  increases.  In addition,  the nature of the
contracts  with the few wholesale  customers  effectively  prevents  recovery of
merger-related  costs.  These  facts and the  related  commitments  are  further
described in the Lubbock Testimony and the Kirkwood Testimony.

     There are six BECO generation  requirements  customers:  the  Massachusetts
Port Authority ("MPA"),  which principally takes service for Logan Airport;  the
Massachusetts Bay Transportation Authority ("MBTA"), and the Towns of Braintree,
Concord,  Reading  and  Wellesley.  Cambridge's  requirements  customer  is  the
Belmont. The following table contains information regarding those customers.

     As described in the Lubbock Testimony, BECO's rates to Braintree,  Concord,
the MBTA,  Reading and  Wellesley  incorporate  fixed demand  charges and energy
charges.  The Braintree,  Concord,  MBTA and Wellesley  contracts are subject to
annual increases,  in amounts  previously agreed upon which will not be affected
by  merger-related  costs.  The  Reading  contract  is also  subject  to  annual
increases based on charges in the GDPIPD Index, which obviously does not vary in
a manner that would reflect merger  costs.22 As a consequence of recent contract
renegotiations,  the rates under the  Braintree,  MBTA,  Reading  and  Wellesley
contracts were reduced by approximately 10%.23

     Similar contract negotiations with Concord were unsuccessful.  However, the
fixed rate to Concord, and the pre-agreed upon annual increases,  do not include
any  merger  costs.  Therefore,  BECO will not be able to recover  merger  costs
during the life of the Concord contract.24

     The fixed rate to the MPA was negotiated  several years ago and, as a fixed
rate, was not designed to allow recovery of merger-related costs. Therefore, all
of BECO's  requirements  customers are being served under fixed-rate  contracts.
Fixed rates are among the ratepayer  protection  mechanisms which the Commission
has endorsed, and those contracts will hold all of these customers harmless from
increases due to the merger.

     24 Id. at 15-16.  In 2002,  Concord does convert to cost of service  rates.
However, BECO will have to submit a detailed cost of service to support that new
Concord  rate.  At that  time,  BECO will have the burden of  demonstrating  and
quantifying  the extent to which its cost data include  merger costs in the cost
of service. To the extent that merger costs are included in the cost of service,
BECO will have to prove the existence of merger savings in the amounts needed to
offset those costs.

     As described by Mr.  Kirkwood,  other than market rate customers,  the only
wholesale customer served by a CES subsidiary is Belmont.25 Belmont is served by
Cambridge under a Net Requirements  Power Supply Agreement  ("NRA") on file with
the  Commission.  Both the current  rates,  and the rates  under an  agreed-upon
settlement with Belmont are described in detail in the Kirkwood Testimony.26 The
NRA's currently effective rates consist of a demand charge and an energy charge.
The demand rate is currently set at a fixed level  subject to upward  adjustment
if Cambridge  under-recovers  its cost of service at a 3 percent rate of return.
The energy charge tracks costs.  Even if this rate were to remain in place,  the
proposed merger would not affect the cost components of this rate.  Cambridge is
not being merged with another  public  utility and the proposed  merger will not
change its service territory or affect its operations.  As a result,  the merger
would not cause a change in its  operating  costs and the inputs to the  formula
will be unaffected as a result of the merger.

     More importantly,  on January 15, 1999, Cambridge and Belmont filed a Joint
Offer of Settlement  with the  Commission  that would amend the NRA to eliminate
the rates and charges

     25 Kirkwood  Testimony at 9 et seq. Canal previously  provided its share of
the  capacity  and  energy  from  Canal  Unit 1 and  Canal  Unit 2 to  wholesale
customers.  However, in the divestiture proceeding,  the Commission approved the
assignment of Canal's Canal Unit 1 power sales  agreements to Southern Canal. As
described in the Section 203 application  filed in the  divestiture  proceeding,
Docket Nos.  EC98-50-000 et al., the  agreements  for Canal's  interest in Canal
Unit 1 were with the following utility purchasers: Montaup Electric Company, New
England Power Company, BECO, and Cambridge and Commonwealth.

     Canal  previously  sold its share of capacity and energy in Canal Unit 2 to
its affiliates,  Cambridge and Commonwealth. In connection with the divestiture,
Cambridge, Commonwealth and Canal mutually agreed to terminate those power sales
agreements.  As planned, the parties terminated those agreements upon closing of
the sale to Southern Canal on December 30, 1998.

section and set forth a fixed monthly  customer charge and energy  charge.27 Mr.
Kirkwood states,  the settlement  rates would "sever any connection  between the
rates and charges and  Cambridge's  cost of service."28 The customer charge will
remain fixed.  The energy charge varies by year, but each yearly charge reflects
a  predetermined  amount that has already been agreed to by the parties.  If the
settlement  is accepted by the  Commission  and its fixed rates go into  effect,
then Cambridge would be required to make a separate  Section 205 filing with the
Commission  before it could modify those rates. As with the BECO contracts,  the
fixed  rate  settlement  with  Belmont   protects  that  customer   against  any
merger-related  increases.  Thus,  both under the old rates and under the recent
settlement,   Belmont  is  fully  protected  from  any  rate  increases  due  to
merger-related costs.29

     The hold-harmless  commitment also extends to transmission customers.  Both
BECO and the CES  subsidiaries  commit to exclude  any merger  costs that exceed
merger savings from transmission  rates. Under similar  circumstances,  FERC has
held that transmission customers will be sufficiently protected from any adverse
effect of the merger upon rates.30

     The  Applicants  have not  submitted a joint  transmission  rate for use of
their PTF as part of this  application  because they are  participants in NEPOOL
and the use of  their  PTF is  governed  by the  NEPOOL  Tariff  and by  ISO-New
England. Thus, there can be no pancaking of transmission

charges for the use of the Applicants' PTF. The Applicants  believe that, in the
vast  majority of  instances,  the  Combined  Company  cannot  collect two local
service charges (LNS or point-to- point) for a transaction originating in one of
the Combined Company's non-PTF  transmission  systems and terminating in another
of those systems and using the local  facilities of both  transmission  systems.
However, the Applicants are conducting an analysis to determine the very limited
circumstances  in which it might be possible for the Combined Company to recover
two local service charges for a single transaction.  If any such pancaking could
occur,  the Applicants  commit to making a corrective  transmission  rate filing
with the  Commission  under the  provisions  of Section 205 of the Federal Power
Act.

     Thus,  given the fixed-rate  nature of the wholesale  contracts (and of the
pending settlement with Belmont), the Applicants' hold harmless commitments, and
the fact that the public utility subsidiaries are not being combined,  there are
no circumstances in which the merger will have an adverse impact upon rates.

     C.   The Merger Will Not Impair Effective Regulation

     The merger also will not affect  regulation.  The Merger  Policy  Statement
mandates a waiver of merger  applicants'  Ohio Power  immunity  out of a concern
that  the  merger  could  result  in the  loss to the  Securities  and  Exchange
Commission  ("SEC") of this  Commission's  regulatory  authority for rate making
purposes over  inter-affiliate  transactions.31  The merger will not affect this
Commission's regulatory jurisdiction.  After the merger, BEC Newco will continue
to be an exempt PUHCA  holding  company with the result that the merger will not
reduce this Commission's jurisdiction. Nevertheless, in the event that BEC Newco
is unable to maintain its

exempt  status  at any  time  in  the  future,  BEC  and  CES  will  follow  the
Commission's  policy  regarding  the  treatment  of the  costs and  revenues  of
affiliate  non-power  transactions  for  Commission  ratemaking  purposes.  This
commitment  is intended to eliminate  the  potential  concern of the  Commission
regarding pre-emptive SEC jurisdiction under the holding of Ohio Power. Nor will
the merger impair existing state regulation,  because the Massachusetts DTE must
approve the retail rates and the rate plan filed with the  Massachusetts  DTE in
conjunction with the merger.

     In sum, both state and federal  jurisdiction will remain unchanged and will
not be impaired by the proposed merger.

VI.  THE ACCOUNTING TREATMENT WILL BE CONSISTENT WITH COMMISSION PRECEDENT

     As described in further  detail in Section VII hereof,  the  accounting for
the  merger  transaction  will be  based  on the  "purchase"  method  which  the
Commission  has approved where it is required by Generally  Accepted  Accounting
Principles  ("GAAP").32  Here,  GAAP requires the  Applicants to account for the
merger  using the  "purchase"  accounting  method.  This is  because,  under the
Accounting Principles Board ("APB") Opinion No. 16, Business  Combinations,  the
purchase method must be used to account for a business combination when at least
one of the criteria required for use of the "pooling of interests" method is not
met. The proposed merger does not meet all of the pooling criteria.  In order to
satisfy the  criteria,  the  companies  may not have  disposed of a  substantial
amount of their assets  within a five year period prior to  announcement  of the
transaction. Because both Companies here have disposed of their electricity

               a.   CES

     CES, by virtue of its ownership of Commonwealth, Cambridge and Canal, is an
electric utility holding company under the Public Utility Holding Company Act of
1935 and is exempt from registration  under the terms of Section 3(a)(1) of that
Act.34

               b.   CES's FPA-Jurisdictional Subsidiaries

     CES's generation owning subsidiaries,  Commonwealth,  Cambridge, and Canal,
recently  divested most of their generation  assets. A brief  description of the
respective  companies'  generation  assets sold to Southern  Canal and  Southern
Kendall  is  provided  below  by  company.  Also  set  forth  below  is a  brief
description  of each company's  remaining  generation  assets,  as well as their
transmission and distribution systems.

     The sale of generating  assets by  Commonwealth,  Cambridge,  and Canal and
their restructuring plans going forward are part of a longstanding  intention of
the  companies to divest their power supply  portfolio.  The following are steps
Commonwealth, Cambridge, and Canal have taken as part of that effort:

     o    In February 1996, they publicly announced their intention to divest of
          their power supply through a competitive auction process and exit from
          the generation business.

     o    On February  27, 1998,  the  Massachusetts  DTE approved  Cambridge's,
          Canal's, and Commonwealth's overall restructuring plan.35

     o    Cambridge,  Canal, and Commonwealth received final bids on May 8, 1998
          and  Southern  Energy New  England,  LLC was selected as the winner of
          their generation assets.

all of  Commonwealth's  generation  assets  to  Southern  Canal by  order  dated
November 12, 1998.37 The sale included the following generation facilities:  (1)
five  diesel  generating  plants at Oak  Bluffs  and West  Tisbury  on  Martha's
Vineyard,  Massachusetts  with a total  capacity  of 13.8 MW;  and (2) a 1.4325%
ownership  interest in the oil-fired William F. Wyman Unit 4 located in Yarmouth
Maine, operated by Central Maine Power Company.  Commonwealth's  interest in the
William F. Wyman  Unit 4  translated  into a 8.9 MW  entitlement.  As  described
above, the transaction with Southern Canal closed on December 30, 1998.

     Commonwealth also provides customers with transmission  services to others,
including  transmission  service  under its Open Access  Transmission  Tariff.38
Commonwealth  also  owns  and  operates  approximately  357.5  circuit  miles of
interconnected  transmission  lines  of  115  kV  to  345  kV,  including  297.6
circuit-miles  of  115  kV  lines  and  59.9  circuit-miles  of  345  kV  lines.
Transmission  facilities  include  substations  with a capacity of approximately
475,000 kilovolt- amperes.  All of these transmission  facilities are located in
Massachusetts.  A map of Commonwealth's  transmission  facilities is included in
Exhibit  I. As  explained  above,  the  Commission  conditionally  approved  the
formation  of the  ISO-New  England and  authorized,  on an interim  basis,  the
transfer  of  control of  transmission  facilities  owned by the public  utility
members of NEPOOL as part of a comprehensive restructuring of NEPOOL on June 25,
1997.39  On  July  1,  1997,  ISO-New  England  was  activated.  Thus,  although
Commonwealth continues to own its

circuit miles and substations with a capacity of approximately 1,814 MVA.

     Cambridge Electric Light Company

     Cambridge is a franchised  electric public utility engaged in the purchase,
transmission,  distribution and resale of power and energy in Massachusetts  and
is a public  utility as defined in Section  201(e) of the Federal  Power Act, 16
U.S.C. ss. 824(e). Cambridge is a wholly owned subsidiary of CES.

     Cambridge's  electric  service  territory  covers about 7 square miles.  It
provides   retail   service  in  the  City  of  Cambridge,   Middlesex   County,
Massachusetts to some 45,900 electric  customers.  In addition,  Cambridge sells
power for resale through NEPOOL  pursuant to FERC-  approved  market-based  rate
authority,40 and Belmont under a FERC-filed NRA.

     As mentioned  above, the Commission  recently  approved the sale of most of
Cambridge's  generation  assets to Southern  Kendall by order dated November 12,
1998.41  Prior  to the sale to  Southern  Kendall,  Cambridge  was  primarily  a
transmission and distribution  utility.  However,  it did own the 113 MW Kendall
Generating  Station and the 13.5 MW Blackstone  Station facility both located in
Cambridge,  Massachusetts.  Cambridge sold the 113 MW Kendall Generating Station
to Southern Kendall as part of the transaction that closed on December 30, 1998.

Blackstone  Station facility is used  substantially  for the production of steam
for  resale to retail  customers.  Currently,  Cambridge  is  reviewing  several
options  with  regard  to the  Blackstone  Station  facility  and will  seek the
necessary approvals when any transaction is finalized.

     Cambridge also provides  customers with  transmission  services,  including
transmission service under its Open Access Transmission  Tariff42 and individual
contracts.  As described above in the discussion on Commonwealth's  transmission
facilities, although Cambridge continues to own its transmission facilities, PTF
usage will be governed by the ISO-New England.

     Cambridge  also  owns  and  operates  approximately  7.3  circuit  miles of
interconnected  transmission lines of 13.8 kV to 115 kV. Transmission facilities
include substations with a capacity of approximately  311,000  kilovolt-amperes.
All of these  transmission  facilities  are located in  Massachusetts.  A map of
Cambridge's  transmission  facilities  is  included  in Exhibit  I.  Cambridge's
electric  distribution  system consists of  approximately  584 circuit miles and
substations with a capacity of approximately 218 MVA.

     Canal Electric Company

     Canal, a wholly owned  subsidiary of CES, is a public utility as defined in
Section 201(e) of the FPA, 16 U.S.C. ss. 824(e) engaged in the purchase and sale
of electricity at wholesale.  Canal holds no  franchise-like  authority and does
not own,  operate or control  any  transmission  or  distribution.  Canal  sells
electric energy at wholesale to its affiliates Cambridge and Commonwealth, under
rate  schedules  and  tariffs  on file  with the  Commission  but has no  retail
customers. With the exception of an ownership interest in the Seabrook 1 nuclear
power facility, Canal recently divested of its generation interests in a sale to
Southern Canal. Specifically, that

sale included  Canal's oil fired 566 MW Canal Unit 1 generating unit and Canal's
50  percent  ownership  interest  in the 565 MW  Canal  Unit 2.  The  Commission
approved  the  jurisdictional  aspects of the sale of these  assets to  Southern
Canal by order dated  November 12,  1998.43 The sale to Southern Canal closed on
December 30, 1998.

                    ii.  Power  Marketing  Subsidiary --  COM/Energy  Marketing,
                         Inc.

     CES has a power  marketing  subsidiary  that is a public  utility under the
Federal  Power Act,  CEM.  CEM has no physical  facilities  for the  generation,
transmission,  or  distribution  of  electric  power for sale,  nor does it hold
franchises or have service  territories  for the  transmission,  distribution or
sale of  electric  power in the United  States.  It does not own  jurisdictional
facilities other than rate schedules,  contracts,  and books and records (to the
extent they are used in connection with wholesale power supply transactions).

     The Commission  has authorized CEM to sell power in interstate  commerce at
market-  based rates upon  finding that the company  could not  exercise  market
power because it does not have market power over generation or transmission, nor
can it erect barriers to entry to relevant  markets.44 Further details regarding
the  activities  of this  entity can be found in the  quarterly  power  marketer
filings,  and related  filings  submitted in the following  dockets:  COM/Energy
Marketing,  Inc.  (ER98-449-001 et seq.).  CES is actively  pursuing the sale of
CEM.

area of  Boston,  Massachusetts  (the  "Facility").  MATEP  has no  transmission
assets.  MATEP, a public utility, has obtained  market-based rate authority from
the  Commission.45  Pursuant  to that  authority,  MATEP sells the output of the
Facility  to  MATEP  LLC,  a  Delaware  limited   liability   company  which  is
wholly-owned  by MATEP,  and MATEP LLC  resells  such steam,  chilled  water and
electricity to several Harvard  University-affiliated  teaching  hospitals under
long-term contract.

     Specifically, MATEP LLC is party to several long-term retail contracts (the
"User Contracts") to provide the steam, chilled water and electric  requirements
of its customers, which include Harvard Medical School, Harvard School of Public
Health,  Harvard  Dental  School,  Harvard  Institutes  of  Medicine,  and  five
Harvard-affiliated  teaching  hospitals,  all located within close  geographical
proximity  of the  Facility  in  Boston,  Massachusetts.  The  terms of the User
Contracts  extend to September  30, 2021,  and require the customers to take and
MATEP LLC to provide the customers' total requirements for steam,  chilled water
and  electricity  from MATEP LLC to the  extent of the  Facility's  capacity  to
provide such products.

Norfolk and Worcester Counties.

                    ii.  Hopkinton LNG Corp.

     Hopkinton LNG Corp.  ("Hopkinton"),  a wholly-owned subsidiary of CES, owns
and operates an LNG facility at Hopkinton,  Massachusetts  for the liquefaction,
storage,  and vaporization of natural gas for Commonwealth  Gas.  Hopkinton also
owns and  operates an LNG storage  facility in Acushnet,  Massachusetts  for the
storage and  vaporization of natural gas for  Commonwealth  Gas. By order issued
March 3,  1998 in  Docket  No.  CP97-156-001,  Hopkinton  was  issued a  blanket
certificate of limited  jurisdiction  under Section 284.224 of the  Commission's
regulations,  authorizing  Hopkinton to engage in the sale and transportation of
natural gas that is subject to the Commission's  jurisdiction  under the Natural
Gas Act.

                    iii. Other Subsidiaries

     In addition to the  companies  identified  above,  CES also owns all of the
stock of COM/Energy  Steam Company (a steam  distribution  company),  COM/Energy
Resources, Inc. (a non-regulated  subsidiary),  Energy Investment Services, Inc.
(a  corporation  organized  to invest the  proceeds  of CES'  affiliates'  asset
generation sales on behalf of utility customers),  COM/Energy Technologies, Inc.
(energy metering equipment) and five real estate trusts.46

          2.   BEC and its Subsidiaries

     BEC and  its  affiliates  are  described  below.  An  organizational  chart

under which BECO, an electric utility, would become a wholly-owned subsidiary of
a holding company. This reorganization was proposed to facilitate the separation
from BECO of unregulated  business activities and to insulate utility ratepayers
from the risks of present and future  non-utility  businesses.  In  September of
1997, this Commission  approved the reorganization as consistent with the public
interest.47  BEC, by virtue of its  ownership  of BECO,  is an electric  utility
holding  company  under the Public  Utility  Holding  Company Act of 1935 and is
exempt from registration under the terms of Section 3(a)(1) of that Act.48

               b.   BEC's FPA - Jurisdictional Subsidiary - BECO

     BECO is an electric  public utility  engaged in the  generation,  purchase,
transmission, distribution and sale of electric energy in Massachusetts and is a
public  utility as defined in Section 201(e) of the Federal Power Act, 16 U.S.C.
ss. 824(e).  BECO's  electric  service  territory  covers about 590 square miles
within 30 miles of Boston,  encompassing  the City of Boston and 39  surrounding
cities and towns.  BECO serves some 663,000 electric  customers at retail.  BECO
also  sells  electric  energy  at  wholesale  to other  electric  utilities  and
municipal electric departments under rate schedules and tariffs on file with the
Commission.  On December 23, 1997, the Commission  accepted BECO's  market-based
rate  tariff  for  filing,  authorizing  BECO  to sell  power  at  wholesale  at
market-based rates.49

     BECO  voluntarily  divested its fossil  generation  business  pursuant to a
Settlement   Agreement   reached  with  the   Massachusetts   Attorney  General,
Massachusetts  Division of Energy  Resources  and other  interested  parties and
filed on July 8, 1997 in restructuring proceedings

before  the  Massachusetts  DTE in Docket  DPU  96-32.  The  generation  already
divested by BECO  included  1,987 MW of  fossil-fired  capacity at six different
sites. BECO accomplished the divestiture  according to competitive bidding which
resulted in the selection of Sithe Energy, Inc. ("Sithe") as the winning bidder.
This Commission  granted Section 203 approval for the transfer of jurisdictional
transmission  facilities  related to the generation from BECO to Sithe in Docket
No. EC98-16-000.50 As described above, BECO's only remaining owned-generation is
its 670 MW Pilgrim  nuclear  power  plant.  BECO and  Entergy  Nuclear  recently
entered into a purchase and sale agreement with Entergy  Nuclear to purchase the
Pilgrim  nuclear power plant.  If the requisite  approvals for this sale are not
obtained,  it is likely  that  BECO,  in the near  future,  would  shut down the
Pilgrim plant and permanently retire it.

     BECO  also  owns  and   operates   approximately   524  circuit   miles  of
interconnected  transmission lines of 115-345 kV, including 176 circuit-miles of
230-345  kV lines and 348  circuit-miles  of 115kV  lines.  BECO's  transmission
facilities include  substations with a capacity of approximately  3,500 MVA. All
of these transmission  facilities are located in Massachusetts.  A map of BECO's
transmission  facilities is included in Exhibit I. BECO's electric  distribution
system consists of  approximately  22,003 circuit miles and  substations  with a
capacity of approximately 10,822 MVA.

     BECO  also  provides  customers  with  transmission   services  to  others,
including  transmission service under its Open Access Transmission  Tariff51 and
individual contracts. As explained above, the Commission  conditionally approved
the formation of the ISO-New England

and  authorized,  on an interim basis,  the transfer of control of  transmission
facilities  owned  by  the  public  utility  members  of  NEPOOL  as  part  of a
comprehensive  restructuring  of NEPOOL on June 25, 1997.52 Thus,  although BECO
continues  to own its  transmission  facilities,  PTF usage will be  governed by
ISO-New England.

               c.   BEC's Non-FPA-Jurisdictional Subsidiaries

                    i.   Harbor Electric Energy Company

         Harbor  Electric  Energy Company  ("Harbor  Electric"),  a wholly owned
subsidiary  of BECO,  delivers  electric  energy from BECO to the  Massachusetts
Water Resources  Authority,  a large retail  customer.  Although Harbor Electric
owns  a  small  distribution   system,  that  system  is  used  exclusively  for
distribution.  In addition,  Harbor  Electric  owns no  generation  and does not
engage in wholesale sales or purchases.

                    ii.  Boston Energy Technology Group, Inc.

     BECO also wholly owns an unregulated  subsidiary,  Boston Energy Technology
Group, Inc.  ("BETG").  BETG has several  subsidiaries and is engaged in various
businesses,  including  energy  conservation  services,  the production of water
treatment systems, and communications  services.  None of these subsidiaries are
FPA-jurisdictional,   nor  do  they  provide  any  gas  distribution,  sales  or
transportation  services.  For example,  through a subsidiary,  BETG has entered
into a  telecommunications  joint  venture  with RCN Telecom  Services,  Inc. to
provide telecommunications services. BETG owns no generation or transmission and
does not engage in wholesale sales or purchases of energy.

     This  application  involves  the proposed  merger of two holding  companies
which own public  utility  subsidiaries,  as well as a change in control  over a
power marketer entity that qualifies as a  jurisdictional  public utility.  This
Application  does not  involve  the  direct  disposition,  by sale or lease,  of
jurisdictional facilities.

     The parties  executed  their  merger  agreement  on  December 5, 1998.  The
following is a summary of the key aspects of the transaction. Exhibit H contains
the  merger  agreement  which  provides  a  more  detailed  description  of  the
transaction.

          1.   Structure of the Transaction

     Under the terms of the agreement, a new holding company will be created and
both BEC and CES will exchange  their shares for a  combination  of stock in the
new holding  company and cash. The parties  anticipate  that at the close of the
transaction, BEC stockholders will own approximately 68% of the combined company
and CES  stockholders  will own  approximately  32%. Upon proper filing with the
SEC, BEC Newco will be an exempt public  utility  holding  company which will be
the parent of BECO and Commonwealth, Cambridge, Canal, Commonwealth Gas, and the
unregulated affiliates of BEC and CES, including CEM and MATEP.

          2.   Merger Consideration

     BEC  stockholders  may elect to receive one share of the holding  company's
common  stock or  $44.10 in cash for each BEC share  they  own.  The cash  price
represents a 5% premium to BEC's closing stock price on December 4, 1998.  CES's
stockholders  may elect to receive 1.05 shares of the holding  company's  common
stock or $44.10 in cash for each CES share they

                                      -35-

<PAGE>



own,  representing  a 17%  premium to CES's  closing  price on December 4, 1998.
Under the merger  agreement,  BEC stockholders will receive  approximately  42.6
million  shares  in the  Combined  Company  and  $200  million  in cash  and CES
stockholders will receive  approximately 20.2 million shares and $100 million in
cash.

          3.   Tax and Accounting Treatment

     The parties  intend that the merger of BEC and CES qualify as a non-taxable
transaction  under  existing  law.  Under  this  structure,   neither  entities'
shareholders  will recognize any gain or loss for federal income tax purposes as
a consequence of the merger except to the extent that shareholders  receive cash
in lieu of common stock BEC Newco. The merger is expected to be accounted for as
a purchase in accordance with GAAP.

          4.   Required Approvals and Consents

     The merger is subject to approval of  stockholders  of BEC and of CES.  The
Massachusetts  DTE must  also  approve  the rate  plan and BEC and CES must also
receive  authorizations  related  to the  merger  from  the  Nuclear  Regulatory
Commission  ("NRC") and the SEC. BEC and CES also shall make the  Department  of
Justice and the Federal Trade  Commission  ("FTC")  pre-merger  notification and
report form filings specified by the Hart-Scott-  Rodino Antitrust  Improvements
Act ("HSR Act"). Under the HSR Act, the parties to a proposed transaction,  such
as BEC  and CES are  required  to wait a  period  of  time  before  closing  the
transaction so that the antitrust  authorities  may review the  transaction  and
decide whether to seek additional information about it or seek to enjoin it.

     E.   Section 33.2(f)

     Under the terms of the merger agreement,  attached hereto as Exhibit H, the
proposed merger between CES and BEC will create a change in control over all the
jurisdictional operating

                                      -36-

<PAGE>



facilities of the parties to the transaction. The jurisdictional facilities will
be operated after the  consummation of the proposed merger in the same manner as
they are currently operated.

     F.   Section 33.2(g)

     No  jurisdictional  facilities  are being  transferred,  by direct  sale or
disposition,  as a result  of the  proposed  merger.  Upon  consummation  of the
proposed merger,  BEC Newco will exercise control over BEC's and CES's regulated
subsidiaries.  The book  costs of the  facilities  involved  in the  merger  are
contained  in the  balance  sheets  attached  hereto as Exhibit C. As  described
above,  here,  GAAP requires the  Applicants to account for the merger using the
"purchase"   accounting   method.53  .  Pursuant  to  the  Applicants'  proposed
implementation  of the purchase method of accounting for this  transaction,  all
assets and  liabilities of CES's regulated  subsidiaries,  as well as the assets
and liabilities of BEC's regulated  subsidiary,  will continue to be valued, for
both FERC  accounting and financial  reporting,  at their  historical  cost less
accumulated  depreciation.  The excess of the consideration for BEC and CES over
their net book value is  currently  planned to be  recorded  on the books of BEC
Newco.

     Applicants  do not intend to "push  down" any  portion  of the  acquisition
premium to the books of any jurisdictional entity. Accordingly,  the acquisition
premium will not affect the capital

- --------
     53 If the requirements of pooling-of-interest accounting were met, then the
balance sheets of BEC and CES would have been combined. Under this approach, for
accounting purposes,  there would be no adjustment (i.e.,  increase or decrease)
to any of the assets or  liabilities  of the merged  entities to account for the
acquisition premium. In a purchase-accounting  transaction,  such as the BEC/CES
combination, any acquisition premium paid is recorded on the books and amortized
over a certain time period, not to exceed 40 years, in accordance with GAAP. For
regulated companies, such as the CES and BEC regulated subsidiaries,  the amount
paid in excess of the net book value on an historical cost basis  represents the
acquisition  premium,  which is  amortized  over a  40-year  period.  Generally,
utility  companies  use a  40-year  period  because  of the  long  lives  of the
underlying assets.

                                      -37-

<PAGE>



structure of either BEC's or CES's regulated  entities,  or any other subsidiary
that provides a regulated service. Moreover, the acquisition premium will not be
included in the establishment of any cost-based regulated wholesale rate. If any
part  of  the  acquisition  premium  is  "pushed"  down  to  the  account  of  a
jurisdictional utility, it will be recorded in the appropriate account, and will
not be recoverable in wholesale rates without further order from the Commission.
This is consistent with Commission precedent.54

     Exhibit  C  to  this   Application   provides   balance  sheets  for  BEC's
jurisdictional subsidiary, and for CES' jurisdictional  subsidiaries.  Exhibit E
provides income  statements for the same companies.  These exhibits  demonstrate
that the proposed  transaction will have no effect on the books of Commonwealth,
Cambridge,  Canal,  or BECO,  and no effect on the ability of the  Commission to
regulate Commonwealth, Cambridge, Canal, or BECO under cost-based ratemaking.

     G.   Section 33.2(h)

     The proposed merger is not anticipated to have any material effect upon any
existing contract for the purchase, sale, or interchanges of electricity.

     H.   Section 33.2(i)

     Filings  with respect to the  transaction  have been or are being made with
the Massachusetts DTE, the SEC, the Department of Justice, the FTC, and the NRC.
Thus far,  filings  have been made with the  Massachusetts  DTE and the SEC. The
filing with the  Massachusetts  DTE is included in Exhibit G.  However,  the SEC
filing, a Preliminary Proxy Filing,  is confidential.  The final version of that
SEC filing,  as well as the PUHCA filing that must be made with the SEC, the NRC
filing, and the pre-merger notification and report form filings specified by the
HSR Act that

must be submitted to the  Department  of Justice and the FTC, will be filed with
the Commission as supplements to this Application.

     I.   Section 33.2(j)

         The  facts  relied  upon to  demonstrate  that the  proposed  merger is
consistent with the public  interest are contained in the preceding  sections of
this application and in the attachments and exhibits hereto and are incorporated
herein by reference.

     J.   Section 33.2(k)

     Canal has no retail franchises or franchise-like authority.

     Cambridge has  franchise-like  authority in the City of  Cambridge,  in the
Commonwealth of Massachusetts.

     Commonwealth  has  franchise-like  authority  in the  Counties  of Bristol,
Barnstable, Dukes, and Plymouth, in the Commonwealth of Massachusetts.

     BECO has  franchise-like  authority  in the  Cities  of  Acton,  Arlington,
Ashland, Bedford, Bellingham,  Boston, Brookline,  Burlington, Canton, Carlisle,
Chelsea, Dedham, Dover, Framingham,  Holliston,  Hopkinton,  Lexington, Lincoln,

Massachusetts.

     It is the Applicants'  position that their affiliates possess perpetual and
exclusive  franchises to distribute gas and/or electricity in the municipalities
that they currently so provide such service.

     K.   Section 33.2(l)

     A draft  notice for  publication  in the  Federal  Register  which  briefly
summarizes the facts of the proposed  merger is attached as Attachment 4 hereto.

regulations, 18 C.F.R. ss. 33.2(l), an electronic version of the draft notice is
also submitted on a 3 1/2" diskette in WordPerfect 5.2 format.

VIII. CONCLUSION

     Applicants   respectfully   request  that  the  Commission  give  expedited
consideration  and  approval to the  proposed  merger.  Expedited  treatment  is
warranted in this case because no  substantive  issues are presented  which cast
any doubt upon the appropriateness of the merger.

     The Commission has committed to swift action in cases,  such as this, which
do not present substantive  issues.55 The proposed merger of BEC and CES plainly
meets all of the Commission's  requirements for expedited  regulatory  approval.
There is virtually no change in HHIs as a result of the merger.  Ratepayers will
be "held  harmless"  from  merger-related  costs and will be protected  from any
other  possible  cost-increases  resulting  from  the  merger  through  existing
mechanisms.  Existing  regulation of the operating  subsidiaries  of the merging
companies  will remain  unchanged.  In light of the clear absence of any adverse
impact on  competition in any market,  any regulated  cost-based  rates,  or the
nature of  regulation,  the merger  satisfies the standards of the Merger Policy
Statement. It should therefore be approved as being "consistent

          Re:  Request for Commission Consent to the Indirect
               Transfer of Control of the Operating License
               Identified Above./1/

     I.  INTRODUCTION

     Boston  Edison  Company  ("Boston   Edison"),   hereby  requests  that  the
Commission  consent to the  indirect  transfer  of  control  of Boston  Edison's
interest in Operating  License No. DPR-35 (the "Pilgrim  Operating  License")/2/
pursuant to Section  184/3/ of the Atomic  Energy Act of 1954,  as amended  (the
"Act"), and 10 CFR ss.50.80. This request is being filed in

- ----------
1    This Request is being filed  concurrently  with a related  filing in Docket
     No. 50-443 that relates to the same transaction.

2    There is currently  pending  before the  Commission  in Docket No. 50-293 a
     request,  dated  December  21,  1998,  for  approval of the Transfer of the
     Pilgrim Operating License from Boston Edison to Entergy Nuclear  Generation
     Company  in  connection  with the sale of  Pilgrim  Station  (the  "Pilgrim
     Sale"),  the consummation of which transaction would render Boston Edison's
     request herein moot. However, it is unclear whether the Pilgrim Sale or the
     Parent Merger will close first, and therefore Boston Edison requests prompt
     processing of its request herein.

connection with the proposed merger of the parent  organization of Boston Edison
with Commonwealth Energy System (the "Parent Merger").

     Transaction  Background:  Boston Edison is a wholly-owned subsidiary of BEC
Energy,  a  Voluntary  Association  organized  under  the laws of  Massachusetts
("BEC"),  and an exempt public utility  holding company under Section 3(a)(1) of
the  Public  Utility  Holding  Company  Act of 1935,  as amended  ("PUHCA").  On
December 5, 1998 BEC and  Commonwealth  Energy  System  ("CES")  entered into an
Agreement and Plan of Merger  pursuant to which those entities will merge into a
new surviving Massachusetts  corporation (the "New Company").  Upon consummation
of the Parent Merger,  the stockholders of BEC and CES will become  stockholders
of New Company (with BEC stockholders  owning  approximately  68% of New Company
and CES stockholders  owning  approximately 32%) and the assets (including their
respective  subsidiaries)  and liabilities of BEC and CES will become assets and
liabilities of New Company.  Therefore, Boston Edison will become a wholly-owned
subsidiary  of New  Company.  Thus,  the Parent  Merger  will effect an indirect
change of control of Boston Edison's interest in the Pilgrim Operating License.

     Pilgrim Background:  Pilgrim Nuclear Power Station ("Pilgrim Station") is a
nuclear  powered  generating  facility owned by Boston Edison and is operated by
Boston Edison pursuant to the Pilgrim Operating  License.  As the original owner
of Pilgrim  Station,  Boston Edison was found to be technically  and financially
qualified to construct,  own and operate Pilgrim  Station.  Granting the request
contained  in  this  submission  will  not in any  way  affect  Boston  Edison's
responsibilities  as operator of Pilgrim Station or any technical aspects of the
Pilgrim Operating License.

     Regulatory  Approvals.  In  addition  to  the  consent  of  the  Commission
requested  hereby,  the  proposed  Parent  Merger will  require  the  regulatory
approvals listed below.

     1.  Massachusetts  Department of  Telecommunications  and Energy  ("MDTE").
Boston  Edison  will  file a rate  plan  for  approval  by the  MDTE  under  the
provisions  of M.G.L.  c. 164,  in order to receive the  appropriate  ratemaking
treatment  for certain of the  transaction  costs  associated  with the proposed
Parent Merger.

     2. Securities and Exchange  Commission  ("SEC").  A preliminary joint proxy
statement  will be filed by BEC and CES for  approval of the merger  transaction
with the SEC, and a second filing will be made with the SEC seeking an exemption
for the New Company under the provisions of the PUHCA.

     3. Federal Energy Regulatory Commission  (""FERC").  An application will be
filed  pursuant to section 203 of the Federal Power Act for FERC approval of the
Parent Merger.

     4. Federal Trade  Commission/Department  of Justice. A letter regarding the
merger transaction will be filed with the United States Federal Trade Commission
and the United States  Department of Justice  pursuant to the  Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended.

II.  APPLICATION FOR CONSENT TO INDIRECT TRANSFER OF CONTROL.

     Pursuant  to 10 CFR  ss.50.80,  Boston  Edison  hereby  requests  that  the
Commission  consent to the  indirect  transfer  of  control  of Boston  Edison's
interest in the Pilgrim  Operating  License which  indirect  transfer of control
will result from the implementation of the Parent Merger described above.

                                       -3-
<PAGE>

     Set forth below is the supporting  information required by the Commission's
implementing regulation, 10 CFR ss.50.80, for an application for consent to such
an indirect transfer.

     involved in the licensed activities. However, in the event such information
     does become  involved,  Boston  Edison  agrees  that it will  appropriately

     access to Restricted  Data until the Office of Personnel  Management  shall
     have made an investigation and reported to the Commission on the character,
     associations and loyalty of such individual,  and the Commission shall have
     determined  that  permitting  such person to have access to Restricted Data
     will not endanger the common defense and security of the United States.

     2. 10 CFR ss.50.33 Financial Information:

          (a) Financial Qualifications for Continued Conduct of Activities:

     Clause  (f)  of  10  CFR   ss.50.33   exempts  an  electric   utility  from
demonstrating  its financial  qualifications.  Boston  Edison  currently is, and
after implementation of the Parent

                                       -7-
<PAGE>

Merger will continue to be, an "electric  utility" as defined in 10 CFR ss.50.2.
Having  sold its fossil  generating  assets,  Boston  Edison's  business  now is
primarily  that of a  transmission  and  distribution  company  where  rates are
regulated by the MDTE and,  until the sale of Pilgrim  Station is  completed/4/,
also involves operation of Pilgrim Station, the output of which is sold in major
part at  retail  to  Boston  Edison  customers  and in part at  wholesale  under
cost-of-service  contracts  approved by FERC.  Therefore,  Boston Edison submits
that it is exempted from the requirements of clause (f) of 10 CFR ss.50.33.

     Without waiving that exemption and to assist the Commission's evaluation of
this Joint Request,  Boston Edison voluntarily submits the following information
relating to its  qualifications  to continue funding its operational  activities
authorized by the Pilgrim Operating License:

     Chapter  164 of the Acts of 1997 (the  "Massachusetts  Restructuring  Act")
established  the  framework  to  restructure  the electric  utility  industry in
Massachusetts.  In  anticipation  of the  Massachusetts  Restructuring  Act  and
consistent  with the  Order,  dated  December  31,  1996,  of the  Massachusetts
Department of Public Utilities (now the MDTE) in Docket No. 96-23, Boston Edison
entered  into a  Settlement  Agreement,  dated July 8, 1997,  with the  Attorney
General  of  Massachusetts  and  other  interested  parties  (a copy of which is
attached as Exhibit A hereto) that was designed to allow full recovery of Boston
Edison's  share  (74.26867%)5  of the sunk costs and the  decommissioning  costs
relating to Pilgrim Station and of the operational

- ----------
4    See footnote 2, supra.

5    The balance of these costs  (25.73133%) are recovered under wholesale Power
     Contracts with other  investor-owned or municipal  utilities that have been
     filed with, and are regulated by, FERC.

activities  at  Pilgrim  Station  based  upon a  performance  based  rate./6/
The Settlement  Agreement was approved by the MDTE by Order, dated January 28,
1998, a copy of which is attached as Exhibit B.

     (b)  Decommissioning  Funding:  Clause (k) of 10 CFR  ss.50.33  requires an
application  for an  operating  license  for a  utilization  facility to contain
information indicating how reasonable assurance will be provided that funds will
be available to decommission the facility.

     On July 26,  1989,  Boston  Edison  submitted  the "Pilgrim  Nuclear  Power
Station  Decommissioning  Funding Report" that  demonstrated how such reasonable
assurance  would be provided by Boston Edison,  which report has been updated as
required by NRC regulations.  Boston Edison has made all required  payments into
its  Decommissioning  Trust.  In  addition,  Section  1G  of  the  Massachusetts
Restructuring Act and the Settlement Agreement both provide that decommissioning
costs will be recovered under a non-avoidable  wires charge to be collected from
ratepayers.

3. 10 CFR ss.50.34 Information:

     Clause  (b)(7)  of 10 CFR  ss.50.34  requires  information  describing  the
technical  qualifications  of the applicant to engage in the proposed  activity.
Boston Edison's technical qualifications were approved in Docket No. 50-293. The
Parent   Merger   does  not  involve  any   modification   of  Boston   Edison's
responsibilities.  The Parent Merger will not affect Boston  Edison's  technical
qualifications. Therefore, clause (b)(7) of 10 CFRss.50.34 is not applicable.

- ----------
6    See Section 2.7 of  Attachment  3 to the  Settlement  Agreement  (Exhibit A
     hereto).

4. 10 CFR ss.50.33a Information:

     Boston Edison has disposed of substantially all of its generation  capacity
as a result of the Massachusetts  Restructuring  Act, except for its interest in
Pilgrim station/7/.  Furthermore, the indirect change of control involved herein
does not represent a transfer to a new owner but only a corporate restructuring.
Finally,  because the Pilgrim  Operating License is issued under Section 104b of
the Act, it is not subject to antitrust review as provided in Section 105 of the
Act. Therefore, no Section 105 antitrust review is required.

III.  CONCLUSION.

     Based upon the foregoing,  Boston Edison, hereby respectfully requests that
the Commission consent to the indirect transfers of control described in Section
II hereof.

     As stated  above,  the  proposed  merger  will  require  several  different
regulatory  approvals,  the timing of which is difficult to predict. In order to
facilitate completion of the merger, the undersigned  respectfully requests that
the  Commission  act on this  Request  as  promptly  as  possible  and  that the
Commission provide that its Consent remain effective until at least December 31,
1999.

                                      Respectfully submitted,

                                      BOSTON EDISON COMPANY

     I. INTRODUCTION

     Canal  Electric  Company  ("Canal"),  for itself as a Joint  Owner/2/ and a
licensee of Seabrook Station, hereby requests that the Commission consent to the
indirect transfer of control of Canal's interest in Operating License No. NPF-86
(the  "Seabrook  Operating  License")  pursuant to Section  184/3/ of the Atomic
Energy Act of 1954, as amended (the "Act"), and 10 CFR ss.50.80. This request is
being filed in connection with the proposed

- ----------
1    This Request is being filed concurrently with a filing in Docket No. 50-293
     that relates to the same transaction.

2    North  Atlantic  Energy  Service  Corporation  ("North  Atlantic")  is  the
     licensed  operator of Seabrook Unit No. 1 and is also  authorized to act as
     agent  for  the  eleven  owners  of the  facility:  North  Atlantic  Energy
     Corporation,  Canal  Electric  Company,  The  Connecticut  Light  and Power
     Company,  Great Bay Power  Corporation,  Hudson  Light & Power  Department,
     Massachusetts  Municipal  Wholesale  Electric  Company,   Montaup  Electric
     Company,  New England Power Company,  New Hampshire  Electric  Cooperative,
     Inc.,  Taunton  Municipal Light Plant and The United  Illuminating  Company
     (collectively  referred to herein as the  "Seabrook  Joint  Owners" or with
     North Atlantic the "Seabrook Licensees").

merger of Canal's parent organization,  Commonwealth Energy System ("CES"), with
BEC Energy (the "Parent Merger").

     Transaction Background:  Canal is a wholly-owned subsidiary of Commonwealth
Energy  System,  a  Massachusetts  Business  Trust  organized  under the laws of
Massachusetts  ("CES"),  and an exempt  public  utility  holding  company  under
Section  3(a)(1) of PUHCA.  On December 5, 1998 CES and BEC Energy,  a Voluntary
Association organized under the laws of Massachusetts  ("BEC")/4/,  entered into
an Agreement and Plan of Merger pursuant to which those entities will merge into
a new surviving Massachusetts corporation (the "New Company"). Upon consummation
of the Parent Merger,  the stockholders of CES and BEC will become  stockholders
of New Company (with BEC stockholders  owning  approximately  68% of New Company
and CES stockholders  owning  approximately 32%) and the assets (including their
respective  subsidiaries)  and liabilities of BEC and CES will become assets and
liabilities  of  New  Company.  Therefore,  Canal  will  become  a  wholly-owned
subsidiary  of New  Company.  Thus,  the Parent  Merger  will effect an indirect
change of control of Canal's interest in the Seabrook Operating License.

     Seabrook Background:. Seabrook Station Unit No. 1 ("Seabrook Station") is a
nuclear  powered  electric  generating  facility  which is  owned by the  eleven
Seabrook Joint Owners pursuant to an Agreement for Joint Ownership, Construction
and Operation of New Hampshire Nuclear Units, dated May 1, 1973, as amended (the
"Joint Ownership Agreement"),  and is operated by North Atlantic pursuant to the
Seabrook Operating License. In accordance with the Joint Ownership Agreement and
the Managing Agent Operating

Agreement, dated as of June 29, 1992, as amended (the "MAOA")/5/, North Atlantic
is the  Managing  Agent for the  eleven  Seabrook  Joint  Owners and as such has
responsibility  for  the  management,  operation  and  maintenance  of  Seabrook
Station.  North Atlantic's  position as Managing Agent and operator was approved
by issuance of Amendment No. 10, dated May 29, 1992,  to the Seabrook  Operating
License.  Granting the request  contained in this submission will not in any way
affect  North  Atlantic's  position as Managing  Agent and  operator of Seabrook
Station or its  responsibilities  under the MAOA or any technical aspects of the
Seabrook Operating  License.  Canal is the successor in title to the interest in
Seabrook Station originally acquired by one of its affiliates and currently owns
a 3.52317% interest in Seabrook Station.  Since Canal is an electric utility, it
was found by the  Commission  to be  financially  qualified  without a financial
review  being  required,/6/  and  Canal  continues  to be  listed  as one of the
Seabrook Licensees identified in the Seabrook Operating License.

     Regulatory  Approvals.  In  addition  to  the  consent  of  the  Commission
requested  hereby,  the  proposed  Parent  Merger will  require  the  regulatory
approvals listed below.

     1.  Massachusetts  Department of  Telecommunications  and Energy  ("MDTE").
Certain  affiliates of Canal that provide retail electric public utility service
under  Massachusetts  law/7/  will  file a rate plan for each  affected  utility
company for approval by the MDTE under the

     Agent for Seabrook Station, dated November 13, 1990.

     Massachusetts are Cambridge Electric Light Company,  Commonwealth  Electric
     Company and Commonwealth Gas Company.

provisions  of M.G.L.  c. 164,  in order to receive the  appropriate  ratemaking
treatment  for certain of the  transaction  costs  associated  with the proposed
Parent Merger.

     2. Securities and Exchange  Commission  ("SEC").  A preliminary joint proxy
statement  will be filed by CES and BEC for  approval of the merger  transaction
with the SEC, and a second filing will be made with the SEC seeking an exemption
for the New Company under the provisions of the PUHCA.

     3. Federal Energy Regulatory Commission  (""FERC").  An application will be
filed  pursuant to section 203 of the Federal Power Act for FERC approval of the
Parent Merger.

     4. Federal Trade  Commission/Department  of Justice. A letter regarding the
merger transaction will be filed with the United States Federal Trade Commission
and the United States  Department of Justice  pursuant to the  Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended.

II.  APPLICATION FOR CONSENT TO INDIRECT TRANSFER OF CONTROL.

     Pursuant to 10 CFR  ss.50.80,  Canal hereby  requests  that the  Commission
consent to the indirect  transfer of control of Canal's interest in the Seabrook
Operating  License,  which  indirect  transfer  of control  will result from the
implementation of the Parent Merger described above.

     Set forth below is the supporting  information required by the Commission's
implementing regulation, 10 CFR ss.50.80, for an application for consent to such
an indirect transfer.

     1. 10 CFR ss.50.33 General Information:

     (a) Name of Licensee: Canal Electric Company will continue to be a Licensee
under the Seabrook Operating License.

                                       -4-
<PAGE>

     (b) Address of Licensee:  The current  business address is One Main Street,
Cambridge, MA 02142, until the Commission is otherwise notified in writing.

     (c)  Description  of  Business:  Canal is an electric  utility  corporation
organized and operating under the laws of the Commonwealth of Massachusetts  and
is a  wholly-owned  subsidiary of CES. In addition,  CES has three  wholly-owned
electric  or gas  distribution  companies,  Cambridge  Electric  Light  Company,
Commonwealth  Electric Company  (together,  the  "Distribution  Affiliates") and
Commonwealth Gas Company,  (collectively with the Distribution  Affiliates,  the
"Retail  Subsidiaries",   and  with  Canal,  the  "CES  System"),  with  service
territories in eastern Massachusetts.  Canal has traditionally functioned as the
generating  company within the CES System,  engaging in the purchase of electric
power at wholesale and the  generation of electric  power which it has resold at
wholesale to the Distribution  Affiliates under contracts containing rates based
upon  cost-of-service  approved  by the  Federal  Energy  Regulation  Commission
("FERC"). The Distribution  Affiliates and Canal hold valid franchises,  permits
and other  rights  which are  necessary  to allow these  companies to conduct an
electric utility business within the territories they serve.

not  endanger  the  common  defense  and  security  of the  United  States.

     (k) Decommissioning: The information under this clause appears in Paragraph
II 2(b) below.

     2. 10 CFR ss.50.33 Financial Information:

     (a) Financial Qualifications for Continued Conduct of Activities:

     Clause  (f)  of  10  CFR   ss.50.33   exempts  an  electric   utility  from
demonstrating  its  financial  qualifications.  Canal  currently  is,  and after
implementation  of the Parent Merger will continue to be, an "electric  utility"
as defined in 10 CFR ss.50.2. Chapter 164 of the Acts of

                                       -8-
<PAGE>

1997 (the  "Massachusetts  Restructuring  Act")  established  the  framework  to
restructure  the electric  utility  industry in  Massachusetts.  Having sold its
fossil generating assets in compliance with the Massachusetts Restructuring Act,
Canal's current business now involves the purchase of power at wholesale and the
generation  of power at Seabrook  Station and sale at wholesale of such electric
energy to the Distribution  Affiliates under  cost-of-service  rates approved by
FERC.  After  implementation  of the Parent Merger,  Canal's  contracts with the
Distribution Affiliates will continue to be regulated by FERC. Therefore,  Canal
submits  that it is  exempted  from the  requirements  of  Clause  (f) of 10 CFR
ss.50.33.

     Without waiving that exemption and to assist the Commission's evaluation of
this Joint Request, Canal voluntarily submits the following information relating
to its qualifications to continue funding its operational  activities authorized
by the Seabrook Operating License.

     Canal specifically calls the Commission's  attention to the fact that Canal
recovers  the full  amount of costs  billed to Canal  associated  with  Seabrook
Station operating costs from the Distribution  Affiliates  pursuant to the terms
of a  cost-of-service  Power Contract between Canal and those  Companies,  dated
September 1, 1986, as amended, that is regulated by FERC. That Contract provides
that, in  consideration of the payment of those costs and Canal's share of other
Seabrook Station charges, the Distribution Affiliates collectively purchase 100%
of Canal's share of the capacity and energy generated at Seabrook Station.  That
Contract  has been  filed with the FERC.  The  Distribution  Affiliates  in turn
recover those costs from their  respective  retail customers under rates subject
to the jurisdiction of the MDTE.

     (b)  Decommissioning  Funding:  Clause (k) of 10 CFR  ss.50.33  requires an
application  for an  operating  license  for a  utilization  facility to contain
information indicating how reasonable assurance will be provided that funds will
be available to decommission the facility.

                                       -9-
<PAGE>

     The Seabrook Licensees previously filed on December 27, 1989, as updated on
July 23, 1990, a Report  demonstrating  how such  reasonable  assurance would be
provided by the Seabrook  Licensees,  including Canal,  collectively.  Canal has
made all required payments into the Seabrook  Decommissioning  Trust Fund. After
the Parent  Merger is  implemented,  Canal  will  continue  to make its  ongoing
payments to the Seabrook Decommissioning Trust Fund and will continue to collect
it's share of the Seabrook Station decommissioning and other post shutdown costs
from the  Distribution  Affiliates  pursuant to the terms of the aforesaid Power
Contract  between Canal and those Companies dated September 1, 1986, as amended.
The  Distribution  Affiliates  in turn are  assured  of  recovering  100% of the
Seabrook  decommissioning costs included in the payments due to Canal under that
Contract  from their  respective  retail  customers  under rates  subject to the
jurisdiction  of the MDTE  and  approved  in  connection  with the CES  Electric
Restructuring Plan (a copy of which is attached as Exhibit A hereto),  which was
approved by the MDTE on February 27, 1998 in Docket No.  DPU/DTE  97-111 (a copy
of which is attached as Exhibit B hereto).

3. 10 CFR ss.50.34 Information:

     Clause  (b)(7)  of 10 CFR  ss.50.34  requires  information  describing  the
technical  qualifications  of the applicant to engage in the proposed  activity.
Pursuant to the MAOA,  North  Atlantic is the  Managing  Agent for the  Seabrook
Joint Owners and, as such, has responsibility for the management,  operation and
maintenance of Seabrook Station. North Atlantic's technical  qualifications were
approved in connection with Amendment No. 10 to the Seabrook  Operating  License
in Docket No. 50-443. The Parent Merger will not affect the

                                      -10-
<PAGE>

technical qualifications of North Atlantic nor involve any modification of North
Atlantic's other responsibilities. Therefore, clause (b)(7) of 10 CFRss.50.34 is
not applicable.

4. 10 CFR ss.50.33a Information:

     CES has  disposed  of  substantially  all of its  generation  capacity as a
result of the Massachusetts  Restructuring  Act, except for the nuclear interest
that is the subject of this Request and other minor  interests./8/  Furthermore,
the indirect change of control  involved herein does not represent a transfer to
a new owner but only a corporate  restructuring.  Finally,  Canal's  interest in
Seabrook Station amounts to only approximately 40MW and therefore  constitutes a
de minimis interest. Therefore, no Section 105 antitrust review is required.

III.  CONCLUSION.

     Based  upon the  foregoing,  Canal  Electric  Company  hereby  respectfully
request  that the  Commission  consent  to the  indirect  transfers  of  control
described in Section II hereof.

     As stated  above,  the  proposed  merger  will  require  several  different
regulatory  approvals,  the timing of which is difficult to predict. In order to
facilitate  completion of the merger, the undersigned  respectfully request that
the  Commission  act on this  Request  as  promptly  as  possible  and  that the
Commission provide that its Consent remain effective until at least December 31,
1999.

Filing under the Public Utility Holding Company Act of 1935
_____________________, 1999

NSTAR  (70-         )

         NSTAR (the  "Company"),  800  Boylston  Street,  Boston,  Massachusetts
02199,  a  Massachusetts  business  trust not currently  subject to the Act, has
filed an  application-declaration  on Form U-1 under  Sections  9(a)(2),  10 and
3(a)(1) of the Act.

         Pursuant to the terms of the Amended and Restated Agreement and Plan of
Merger  dated as of December 5 and  amended and  restated as of May 4, 1999 (the
"Merger  Agreement")  among the Company,  BEC Energy,  a Massachusetts  business
trust ("BEC Energy"), Commonwealth Energy System, a Massachusetts business trust
("COM/Energy"),  BEC Acquisition LLC, a Massachusetts  limited liability company
("BEC Energy Merger Sub"),  and CES  Acquisition  LLC, a  Massachusetts  limited
liability company ("COM/Energy Merger Sub"), the Company proposes to acquire all
of the outstanding  common shares of BEC Energy, a Massachusetts  public-utility
holding  company  exempt  from  registration  under  section  3(a)(1) of the Act
pursuant  to an  order  of  the  Commission,  and  COM/Energy,  a  Massachusetts
public-utility holding company exempt from registration under section 3(a)(2) of
the Act.

         BEC Energy  currently  has two electric  utility  subsidiaries,  Boston
Edison Company  ("Boston  Edison") and Harbor Electric  Energy Company  ("Harbor
Electric"),  both of  which  are  organized  and  operate  as  public  utilities
exclusively in the Commonwealth of Massachusetts.  COM/Energy currently has four
electric  utility  subsidiaries,  Cambridge  Electric Light Company  ("Cambridge
Electric"),  Commonwealth  Electric  Company  ("Commonwealth  Electric"),  Canal
Electric Company ("Canal  Electric"),  and Medical Area Total Energy Plant, Inc.
("MATEP"),   and  one  gas   utility   subsidiary,   Commonwealth   Gas  Company
("Commonwealth Gas"), all of which are organized and operate as public utilities
exclusively  in the  Commonwealth  of  Massachusetts.  BEC Energy Merger Sub and
COM/Energy Merger Sub are both wholly-owned subsidiaries of the Company.

         The transaction  would be effected  through the mergers (the "Mergers")
of BEC Energy Merger Sub with and into BEC Energy (the "BEC Energy  Merger") and
of COM/Energy Merger Sub with and into COM/Energy (the "COM/Energy  Merger"). As
a result of the Mergers,  the Company would be a public-utility  holding company
as defined in section 2(a)(7) of the Act with seven public utility  subsidiaries
(Boston Edison,  Harbor Electric,  Cambridge  Electric,  Commonwealth  Electric,
Canal Electric,  MATEP, and Commonwealth Gas). The Company has also requested an
order of exemption  under section  3(a)(1) from all  provisions of the Act other
than section 9(a)(2).

         BEC Energy was organized in 1998 as a public utility  holding  company.
BEC Energy owns all of the outstanding  common stock of Boston Edison,  which is
engaged in the  generation,  purchase,  transmission,  distribution  and sale of
electric energy in  Massachusetts.  Boston Edison's  electric service  territory
covers about 590 square miles within 30 miles of Boston,  encompassing  the City
of Boston and 39 surrounding  cities and towns.  BEC Energy also owns all of the
outstanding common stock of Harbor Electric, which is engaged in the delivery of
electric  energy  from  Boston  Edison  to  the  Massachusetts  Water  Resources
Authority (the "MWRA"), a large retail customer. Although Harbor Electric owns a
small distribution  system,  that system is used exclusively for distribution to
the MWRA. In addition, Harbor Electric owns no generation and does not engage in
wholesale sales or purchases. For the year ended December 31, 1998, BEC Energy's
operating revenues on a consolidated  basis were  approximately  $1.623 billion,
all of which was derived  from Boston  Edison's and Harbor  Electric's  electric
operations.  Consolidated  assets of BEC Energy and its subsidiaries at December
31, 1998 were approximately $3.214 billion, of which approximately $2.27 billion
consists of identifiable utility property,  plant and equipment.  As of December
31, 1998, there were 47,184,073 common shares of BEC Energy outstanding.

         COM/Energy  was  formed in 1926 as a public  utility  holding  company.
COM/Energy owns all of the outstanding stock of Commonwealth Electric, Cambridge
Electric,  Canal  Electric,  and  Commonwealth  Gas and,  through a wholly-owned
subsidiary, owns all of the outstanding stock of MATEP. Commonwealth Electric is
engaged  in the  purchase,  transmission,  distribution  and resale of power and
energy in  Massachusetts.  Commonwealth  Electric's  electric service  territory
covers  about  1,100  square  miles in 40  communities  located in  southeastern
Massachusetts,  including Cape Cod and Martha's Vineyard.  Cambridge Electric is
engaged  in the  purchase,  transmission,  distribution  and resale of power and
energy in Massachusetts.  Cambridge Electric's electric service territory covers
about 7 square miles in Cambridge,  Massachusetts.  Canal Electric is engaged in
the purchase and sale of  electricity  at  wholesale.  Canal  Electric  holds no
franchise-like  authority and does not own,  operate or control any transmission
or  distribution.  Canal  Electric  sells  electric  energy at  wholesale to its
affiliates  Cambridge  Electric  and  Commonwealth  Electric,  but has no retail
customers..  MATEP owns and operates a 62 MW steam,  chilled  water and electric
generating   facility   located  in  the   Longwood   Medical  area  of  Boston,
Massachusetts.  MATEP  sells  the  output  of this  facility  to a  wholly-owned
subsidiary,  which resells such steam,  chilled water and electricity to several
Harvard  University-affiliated  teaching  hospitals,  which are  adjacent to the
facility within the city of Boston,  under long-term contract.  Commonwealth Gas
is a local gas distribution  company  operating in  Massachusetts.  Commonwealth
Gas' service area is approximately  1,067 square miles and it provides local gas
distribution  service  to  approximately  239,000  customers  in the  Cities  of
Cambridge  and  Somerville in Middlesex  County,  a small portion of the City of
Boston  in  Suffolk  County  and  in  various  other  eastern  and  southeastern
Massachusetts  municipalities  in  Bristol,  Middlesex,  Norfolk,  Plymouth  and
Worcester Counties. For the year ended December 31, 1998, COM/Energy's operating
revenues on a  consolidated  basis were  approximately  $980  million,  of which
approximately $627 million was derived from Commonwealth  Electric's,  Cambridge
Electric's,  Canal Electric's and MATEP'S electric operations, and approximately
$289 million was derived from  Commonwealth  Gas' gas  operations.  Consolidated
assets  of  COM/Energy   and  its   subsidiaries   at  December  31,  1998  were
approximately $1.763 billion, of which approximately


<PAGE>


                                      - 3 -

$673 million  consists of  identifiable  electric  utility  property,  plant and
equipment, and $271 million consists of identifiable gas utility property, plant
and equipment.  As of December 31, 1998, there were 21,540,550  common shares of
COM/Energy outstanding.

         The Company was formed under the laws of Massachusetts  for purposes of
facilitating  the Mergers.  At present,  all of the common shares of the Company
are held by BEC Energy and COM/Energy.

         Upon  consummation  of the  Mergers:  (1) each  issued and  outstanding
common  share of BEC Energy  (other than shares held by BEC Energy,  COM/Energy,
the Company or their subsidiaries,  which shall be canceled) that was issued and
outstanding  immediately  prior to such merger shall be converted into the right
to receive  either  $44.10 in cash or one common share of the Company;  (2) each
issued and outstanding common share of COM/Energy (other than shares held by BEC
Energy, COM/Energy, the Company or their subsidiaries,  which shall be canceled)
that was  issued  and  outstanding  immediately  prior to such  merger  shall be
converted  into the right to receive either $44.10 in cash or 1.05 common shares
of the  Company;  (3) each 1%  membership  interest  in BEC  Energy  Merger  Sub
outstanding immediately prior to such merger shall be converted into one hundred
common  shares of BEC Energy;  (4) each 1%  membership  interest  in  COM/Energy
Merger Sub outstanding  immediately prior to such merger shall be converted into
one  hundred  common  shares of  COM/Energy;  and (5) each  common  share of the
Company held by BEC Energy or by COM/Energy shall be canceled.

         As a result  of the  Mergers,  each BEC  Energy  common  share and each
COM/Energy common share (other than shares held by BEC Energy,  COM/Energy,  the
Company or their  subsidiaries  and  affiliates,  which will be  canceled)  will
effectively  be converted into the right to receive cash or common shares of the
Company.  Subject  to  certain  restrictions  on the  amounts  of cash and share
consideration  to  be  issued,   described  below,  BEC  Energy  and  COM/Energy
shareholders  will be able to elect the type of consideration  they will receive
from the  Company in the  Mergers.  The total cash  consideration  to be paid in
connection  with the Mergers will be $300 million,  with $200 million to be paid
to  shareholders  of BEC  Energy  pursuant  to the BEC Energy  Merger,  and $100
million to be paid to  shareholders  of  COM/Energy  pursuant to the  COM/Energy
Merger.  Because the amount of cash  consideration is fixed, it is possible that
some  shareholders  electing  to receive  cash in the BEC  Energy  Merger or the
COM/Energy Merger, as the case may be, may receive shares of the Company in lieu
of some or all of the  cash  that  they  elected  to  receive  and,  conversely,
shareholders  electing to receive shares of the Company may receive cash in lieu
of some or all of the shares of the Company that they elected to receive. In the
event that  shareholders  of  COM/Energy  or of BEC Energy  make cash  elections
exceeding the cash consideration initially allocated to such shareholders (i.e.,
$200 million, in the case of shareholders of BEC Energy, and $100 million in the
case of shareholders of COM/Energy),  and the  shareholders of the other company
make  cash  elections  for less  than all of the  cash  consideration  initially
allocated to such shareholders,  some or all of the cash initially  allocated to
the shareholder group that  under-elected cash consideration may be allocated to
the over-electing shareholder group.

         The Company  states that the Mergers are expected to be tax-free to BEC
Energy and  COM/Energy  shareholders,  to the extent  that they  receive  common
shares of the Company.  It is expected that,  following the  consummation of the
Mergers,  the  shareholders  of BEC Energy and  COM/Energy  would own securities
representing approximately 62% and 38%, respectively,  of the outstanding voting
power of the Company.

     The Mergers are subject to  customary  closing  conditions,  including  the
receipt  of the  requisite  approvals  of the  shareholders  of BEC  Energy  and
COM/Energy.  The BEC Energy shareholders  meeting with respect to the Mergers is
expected to be held on June 25, 1999,  and the COM/Energy  shareholders  meeting
with  respect  to  the  Mergers  is  expected  to be  held  on  June  24,  1999.
Consummation  of the Mergers is also  subject to receipt of certain  rulings and
opinions  relating to federal income tax issues and the expiration of the review
period  under the  Hart-Scott-Rodino  Antitrust  Improvements  Act of 1976.  The
Mergers  require the approval of the Federal Energy  Regulatory  Commission (the
"FERC") and the Nuclear  Regulatory  Commission.  The Mergers do not require the
approval of the Massachusetts  Department of  Telecommunication  and Energy (the
"MDTE"),  which  regulates  electric and gas  utilities in  Massachusetts;  as a
condition to the Mergers,  however,  the utility  subsidiaries of BEC Energy and
COM/Energy  must file and must obtain the  approval of rate plans from the MDTE.
Assuming that the MDTE approves the rate plans,  following the  consummation  of
the Mergers the utility  operations of the Company's  utility  subsidiaries will
remain subject to regulation by the MDTE.

         The Company states that  following the Mergers,  it will be entitled to
an exemption from all provisions of the Act except  section  9(a)(2)  because it
and each of its  public  utility  subsidiaries  from which it derives a material
part of its income will be predominantly  intrastate in character and will carry
on  their  utility   businesses   substantially   within  the   Commonwealth  of
Massachusetts.

         For the Commission, by the Division of Investment Management,  pursuant
to delegated authority.
