                                 JOINT PROPOSAL

     This Merger & Gas Revenue  Requirement Joint Proposal ("Joint Proposal") is
made as of the 6th day of July, 2007 by and among KeySpan Corporation (KeySpan),
The Brooklyn Union Gas Company d/b/a KeySpan  Energy  Delivery New York (KEDNY),
KeySpan Gas East Corporation  d/b/a KeySpan Energy Delivery Long Island (KEDLI),
National Grid plc (National  Grid),  Niagara Mohawk Power  Corporation  (Niagara
Mohawk),  the Staff of the New York State  Department of Public Service (Staff),
the New York State Consumer  Protection  Board, the City of New York, the Public
Utility Law Project,  the International  Brotherhood of Electrical Workers Local
97, and the other parties executing  signature pages  (collectively  referred to
herein as "the Signatory Parties").  To the extent that a Signatory Party is not
supportive of a particular provision of the Joint Proposal, they have noted that
on their signature page(s).

I.   PROCEDURAL BACKGROUND

     On July 20, 2006,  National  Grid and KeySpan filed with the New York State
Public  Service  Commission  (Commission)  a joint  petition  for  approval of a
proposed  acquisition  of the  stock of  KeySpan  by  National  Grid  and  other
regulatory approvals (Merger Filing). Case 06-M-0878 was instituted to provide a
process for the Commission to consider the petition. The Merger Filing was later
updated.

     On October 3, 2006,  KEDNY filed with the Commission  revised tariff leaves
intended to increase revenues from gas operations by approximately  $213 million
for the 12  month  period  ending  March  31,  2008  (KEDNY  Rate  Filing).  The
Commission  instituted  Case  06-G-1185 to consider  the KEDNY Rate Filing.  The
KEDNY Rate Filing was later  updated.  The revised  tariff  leaves are currently
suspended.

     On October 3, 2006,  KEDLI filed with the Commission  revised tariff leaves
intended to increase revenues from gas operations by approximately  $159 million
for the 12  month  period  ending  March  31,  2008  (KEDLI  Rate  Filing).  The
Commission  instituted  Case  06-G-1186 to consider  the KEDLI Rate Filing.  The
KEDLI Rate Filing was later  updated.  The revised  tariff  leaves are currently
suspended.





     All three of the  above-mentioned  cases are being  considered  on a common
evidentiary record.

     On November 9, 2006,  the Commission  issued an order  regarding the Merger
Filing  adopting  a negative  declaration  pursuant  to the State  Environmental
Quality  Review Act.  Accordingly,  no  environmental  impact  statement will be
prepared regarding the proposed merger.

     On May 31, 2007, a Joint  Proposal for Interim Energy  Efficiency  Programs
was executed by many of the parties to these  proceedings and was filed with the
Commission.

     On May 11, 2007,  many of the parties to these  proceedings  announced that
they  had  reached  an  agreement  in  principle  on most  terms  of  three-year
"stand-alone" (absent a merger) rate plans for KEDNY and KEDLI (the "Stand-Alone
Rate Plans").  As of yet, a joint proposal setting forth in detail the terms for
which agreement in principle was reached has not been executed.

II.  OVERVIEW

     This Joint Proposal  arises within the merger  proceeding in Case 06-M-0878
and the rate proceedings of KEDNY and KEDLI in Cases 06-G-1185 and 06-G-1186.  A
Notice of Impending  Negotiations  was sent to all persons  reasonably  known to
have an  interest  in the  outcome of  negotiations  and was duly filed with the
Secretary  by letter  dated  November  28,  2006.  After  notice to the parties,
settlement  conferences were held among the parties that desired to participate.
Settlement is now feasible because, after thorough investigation and discussion,
the Signatory  Parties hereto more fully understand  their respective  positions
and recognize that reasonable settlement of the discrete issues addressed herein
is possible.  The Signatory Parties hereto also believe that this Joint Proposal
will further the  objective  of giving fair  consideration  to the  interests of
customers  and utility  investors  alike in assuring  the  provision of safe and
adequate service at just and reasonable rates.


                                       2



     Regarding the proposed merger,  this Joint Proposal  provides the framework
under which the Signatory  Parties can recommend that the acquisition of KeySpan
by National Grid could be approved as being in the public interest.  It provides
safeguards  regarding corporate structure and rules for affiliate  transactions.
It provides  protections  to preserve  the  financial  integrity of the affected
companies  and to help  ensure  access to capital by the utility  affiliates  on
reasonable  credit  terms.  It includes  provisions  to address  concerns  about
vertical market power by providing for divestiture and/or long-term  contracting
arrangements and other safeguards to ensure that transmission  system assets are
not managed in a manner that favors generation assets owned by affiliates to the
detriment of ratepayers.

     If the merger is  consummated,  this Joint Proposal  provides for five-year
revenue  requirement rate plans that provide  significant  economic  benefits to
KEDNY's and KEDLI's customers,  and provides for an allocation of merger synergy
savings to Niagara Mohawk customers.

     This  Joint  Proposal  does not  address  a number  of  issues  in the rate
proceedings  of KEDNY  and KEDLI in Cases  06-G-1185  and  06-G-1186  ("Reserved
Issues").  It is the intent of the  Signatory  Parties that the Reserved  Issues
will be addressed  either (a) in the intended  joint  proposal to Cases in Cases
06-G-1185 and 06-G-1186 setting forth in detail the terms for which agreement in
principle  was  reached  on May  11,  2007;  or (b)  in  "collaboratives"  to be
undertaken by the parties to Cases 06-G-1185 and 06-G-1186 regarding: (i) energy
efficiency  program design (the energy efficiency  collaborative will proceed in
general  accordance  with the  Joint  Proposal  for  Interim  Energy  Efficiency
Programs  filed  with  the  Commission  on  March  31,  2007);   and  (ii)  rate
design/revenue  decoupling/and  low income  revenue  allocation;  or (c) through
litigation at the evidentiary  hearings  currently  scheduled in Cases 06-G-1185
and 06-G-1186 for October 2007. Such Reserved Issues in the rate  proceedings of
KEDNY and KEDLI in Cases  06-G-1185  and  06-G-1186  not addressed in this Joint
Proposal include, among other matters:

     (a)  three-year "stand-alone" rate plans for KEDNY and KEDLI (if the merger
          is not consummated);

     (b)  site  investigation  & remediation  (SIR) costs for the remediation of
          manufactured  gas plant  (MGP)  sites,  potential  incentive  programs
          related thereto, and the potential recovery from electric customers of
          an  allocation of KEDLI SIR costs with the  understanding  that if the
          costs are not recovered from electric customers they will be recovered
          from KEDLI's customers;

     (c)  long-term energy efficiency program design,  performance  targets, and
          budgets  funded  by  a  surcharge  to  supersede  the  Interim  Energy
          Efficiency  Program  proposed in the May 31, 2007 Joint Proposal filed
          in Cases 06-G-1185 and 06-G-1186;


                                       3



     (d)  revenue decoupling;

     (e)  institution of a low income rate program for KEDLI customers;

     (f)  revenue  allocation  and rate  design,  including  but not  limited to
          general rate design  changes,  further  development  of the low income
          rate programs at KEDNY and KEDLI, on-track and business incentive rate
          ("BIR") programs;

     (g)  retail access programs and rate unbundling;

     (h)  safety and reliability  performance  requirements and incentives (with
          the last year's values  continued  without  change until the next rate
          filing);

     (i)  customer service quality performance requirements and incentives (with
          the last year's values  continued  without  change until the next rate
          filing);

     (j)  lost and unaccounted for gas;

In addition to the above,  the following  issues  associated with the merger are
not addressed in this Joint Proposal. These issues (Merger Reserved Issues) will
be addressed in a second phase of this  proceeding.  The Merger  Reserved Issues
are the following:

     (a)  policies, procedures, and agreements for transactions among affiliates
          in compliance with the provisions of Appendix 4; and

     (b)  transfer of gas contracts to Service Company affiliate.

V.   MERGER

     Conditioned  on the terms  included in this Joint  Proposal,  the Signatory
Parties recommend the following  findings,  consents,  and approvals  associated
with the proposed merger between National Grid and KeySpan:

     (a)  The merger of KeySpan  Corporation,  a holding company owning directly
          or indirectly  the common stock of KEDNY and KEDLI,  which are natural
          gas  corporations,  and the common  stock of KeySpan  Generation  LLC,
          KeySpan-Ravenswood LLC, KeySpan-Port Jefferson Energy Center, LLC, and
          KeySpan-Glenwood  Energy Center, LLC, which are electric corporations,
          into a subsidiary of National  Grid plc is consistent  with the public
          interest and is approved under Section 70 of the Public Service Law.

     (b)  The merger of KeySpan  Corporation,  a holding company owning directly
          or indirectly the common stock of KeySpan Communications  Corporation,
          which  is a  telephone  corporation,  into  National  Grid  plc or its
          subsidiary  is  consistent  with the public  interest  and is approved
          under Sections 99 and 100 of the Public Service Law.


                                       7



     (c)  Effective  on the  closing  of the  merger,  KEDNY and KEDLI may adopt
          fiscal  years  ending  March 31,  consistent  with the  National  Grid
          companies.


VI.  CORPORATE STRUCTURE AND AFFILIATE RULES

     Effective on the closing of the merger,  National  Grid will  implement the
Corporate  Structure  and  Affiliate  Rules set forth in  "Appendix  4" attached
hereto and made a part of this Joint  Proposal.  Such  Corporate  Structure  and
Affiliate  Rules  will  continue  in effect  unless  and until  such time as the
Commission authorizes an express change.

     The Corporate  Structure and Affiliate  Rules  authorize  National Grid and
KeySpan  to  consolidate  their  service  companies  and to  adopt  the  general
allocation  approach  now in  place  for the  KeySpan  service  companies.  That
consolidation  will  occur  when the other  required  regulatory  approvals  are
received  and the  required  accounting  systems  are in  place.  At that  time,
National  Grid shall also file with the  Director  of  Accounting,  Finance  and
Economics revised policies,  procedures,  and agreements for transactions  among
affiliates in compliance with the provisions of Appendix 4 for KEDNY, KEDLI, and
Niagara  Mohawk  Power  Corporation  ("Niagara  Mohawk").  That filing  shall be
treated as a Merger Reserved Issue under this Joint Proposal.  Any  disagreement
associated with the filing shall be referred to the Commission for decision.

     In the interim,  the National Grid Service Company shall execute agreements
with the KeySpan operating  companies to provide services after the Merger under
its approved allocation methods, and the KeySpan service companies shall execute
agreements with the National Grid operating  companies to provide services after
the Merger under their approved  allocation  methods.  These  agreements will be
filed with the Commission pursuant to Section 110 of the Public Service Law.

VII. FINANCIAL PROTECTIONS

     Effective on the closing of the merger,  National  Grid will  implement the
financial  protections  for KEDNY and KEDLI set forth in  "Appendix  5" attached
hereto and made a part of this Joint Proposal.  Such financial  protections will
continue in effect  unless and until such time as the  Commission  authorizes an
expressed change.


                                       8



VIII. TREATMENT OF GENERATION & TRANSMISSION ASSETS

A. Ravenswood Station

     If the merger is consummated, National Grid agrees to the following general
principles  regarding  vertical market power and its ownership of the Ravenswood
Station:

     (a)  National Grid agrees to the goal of divesting the  Ravenswood  Station
          in the manner described below;

     (b)  National  Grid agrees that in the period prior to  divestiture  of the
          Ravenswood Station, it shall take steps described below to assure that
          it is  financially  indifferent  to the price of energy in Zone J with
          respect to the output of the Ravenswood Station;

     (c)  National Grid will plan and operate its  transmission  system  without
          regard to the  financial  impacts  that such  actions  may have on the
          profitability of the Ravenswood Station; and

     (d)  National  Grid's  ownership of the  Ravenswood  Station will not alter
          National Grid's commitment to propose and build regulated transmission
          lines that are needed to provide  reliability or economic  benefits to
          customers in New York State.

     To  implement  the  above-stated   general  principles  if  the  merger  is
consummated, National Grid agrees that:

     (1)  By  January 1, 2008,  National  Grid will enter into a single  forward
          financial  sale  contract  for all the energy  output  from the entire
          Ravenswood  Station for up to a three-year  term. The contract will be
          subject to review by Staff to assure that the contract  complies  with
          the  intent of this  Joint  Proposal,  and does not  create any new or
          unanticipated  market power  concerns.  Any dispute  between Staff and
          National  Grid  regarding  the  contract  will  be  submitted  to  the
          Commission for resolution.

     (2)  No less  than  fourteen  months  prior  to the end of the  term of the
          financial sale  described in "(1)" above,  National Grid will issue an
          offering  document  requesting bids for the purchase of the Ravenswood
          Station. If National Grid wishes, it may also simultaneously  issue an
          offering  document   requesting  bids  for  an  alternative   backstop
          long-term  bilateral physical or financial contract (minimum 15 years)
          for all the products of the entire Ravenswood  Station. If the Federal
          Energy  Regulatory  Commission  (FERC)  does  not  allow  a  long-term
          bilateral  physical  contract  for  all  the  products  of the  entire
          Ravenswood   Station,   the  long-term   bilateral  physical  contract
          alternative  shall not be pursued.  If FERC does not allow a long-term
          bilateral  financial  contract  for all  the  products  of the  entire
          Ravenswood   Station,   the  long-term  bilateral  financial  contract
          alternative shall not be pursued. The Signatory Parties recognize that
          under  current FERC rules and the NYISO  Tariff  approval of bilateral
          financial contracts is not required.


                                       9



     (3)  No less than six months prior to the end of the term of the  financial
          sale  described  in "(1)"  above,  National  Grid  will  file with the
          Commission:

          (a)  a petition  under  Section 70 of the Public  Service  Law seeking
               approval to sell the Ravenswood  Station to a  counterparty  that
               does not own any  electric  transmission  facilities  in New York
               State or any generation capacity in Zone J previously divested by
               Consolidated  Edison  (other than NYPA),  with the  understanding
               that such a sale would be subject to approval  by the  Commission
               and FERC on conditions that are reasonably acceptable to National
               Grid  and to the  purchaser,  it  being  the  expectation  of the
               Signatory  Parties  that  the  Commission's  review  of any  such
               Section  70  Petition  would be based on  substantially  the same
               standards and criteria as have been applied by the  Commission in
               reviewing  the  sale of other  generating  stations  divested  by
               Consolidated Edison operating in the New York City market; or

          (b)  a petition seeking approval for an alternative backstop long-term
               bilateral  physical or financial  contract (minimum 15 years) for
               all of the  products  of the  entire  Ravenswood  Station,  which
               petition will be subject to approval by the  Commission to assure
               that  such  contract  complies  with  the  intent  of this  Joint
               Proposal,  and does not  create any new or  unanticipated  market
               power concerns; or

          (c)  a statement  that  National  Grid has not accepted a proposal for
               either a  divestiture  or a long-term  contract  and,  therefore,
               commencing at the end of the term of the financial sale described
               in "(1)",  above,  the  revenues  from all of the products of the
               entire  Ravenswood   Station  (subject  to  the  FERC  qualifying
               provisions  in "(2)"  above)  that  exceed  the cost of  service,
               including an allowed return on investment set by the  Commission,
               will be  transferred  by National Grid and applied to the benefit
               of electric  ratepayers in Zone J in a manner to be determined by
               the Commission.

     (4)  In the  event  that  National  Grid  makes  either  of  the  petitions
          described in "3(a)" or "3(b)" above,  but the  Commission  rejects the
          petition or imposes  conditions that are unacceptable to the purchaser
          or  counterparty,  National  Grid will have a one-time  right to enter
          into a second contract for the sale of energy pursuant to "(1)" above,
          but only for a period of one year,  during  which time  National  Grid
          will repeat the process  described  in "(2)" and "(3)"  above,  except
          that the  fourteen-month  period  provided  for in "(2)" above will be
          reduced to eleven months.

     (5)  In the event that National Grid makes a second  petition  described in
          "3(a)" or "3(b)" above,  by exercising its rights in "(4)" above,  but
          the  Commission  rejects the petition or imposes  conditions  that are
          unacceptable to the purchaser or counterparty  for reasons that do not


                                       10



          reflect  substantially  the same  standards  and criteria as have been
          applied by the  Commission in reviewing  the sale of other  generating
          stations  divested by  Consolidated  Edison  operating in the New York
          City market, National Grid, Staff and any interested party that wishes
          to attend will meet and determine whether there are additional options
          that could be considered in lieu of a cost-of-service approach.

     (6)  The revenues from all of the products of the entire Ravenswood Station
          that  exceed  the cost of  service,  including  an  allowed  return on
          investment set by the Commission, will be transferred by National Grid
          and  applied to the  benefit  of  electric  ratepayers  in Zone J in a
          manner to be determined by the Commission:

          (a)  commencing  January  1,  2008 if  National  Grid does not make an
               approved  financial  sale  described in "(1)" above by January 1,
               2008;

          (b)  commencing  upon the  expiration of any approved  financial  sale
               described in "(1)" or second  financial  sale  described in "(4)"
               above unless  replaced by divestiture or an alternative  backstop
               long-term  bilateral  physical or financial  contract (minimum 15
               years) for all of the products of the entire Ravenswood  Station;
               and

          (c)  commencing  upon  the  expiration  of  any  alternative  backstop
               long-term   bilateral   physical  or  financial  contract  unless
               replaced by divestiture or another alternative backstop long-term
               bilateral  physical or financial  contract (minimum 15 years) for
               all of the products of the entire Ravenswood Station.

     (7)  In the event  the  revenues  from all of the  products  of the  entire
          Ravenswood  Station  that  exceed the cost of  service,  including  an
          allowed  return  on  investment  set  by  the   Commission,   will  be
          transferred  by  National  Grid and applied to the benefit of electric
          ratepayers in Zone J in a manner to be  determined by the  Commission,
          the following shall apply:

          (a)  The cost of service  associated with the Ravenswood  Station will
               be  set  by  the  Commission  from  time  to  time  in  the  same
               substantive  manner as the  Commission  used when it set electric
               rates that included regulated costs for electric  generation with
               an equity  return  calculated  using the  average of the  Implied
               Return on the Standard & Poor's 500 and the Requied Return on the
               Standard & Poor's 500 as published in Merrill Lynch  Quantitative
               Profiles. .

          (b)  Staff  will have free  access  to all the  books and  records  of
               National Grid and its  affiliates  that relate to the  Ravenswood
               Station.

          (c)  The rate base for the cost of service  will be based on KeySpan's
               purchase  price for the  Ravenswood  Station,  together  with any
               reasonable  investments made by KeySpan in the Ravenswood Station


                                       11



               since  its  acquisition  of the  plant,  including  the  cost  of
               construction   of  KeySpan's  new  combined  cycle  plant,   less
               retirements  and   depreciation   assuming  that  the  Ravenswood
               combined cycle Unit 40 was financed in a manner that would be on-
               balance  sheet rather than financed  off-balance  sheet through a
               sale-lease-back transaction.

          (d)  The mechanism described above for calculating the cost of service
               associated with the Ravenswood Station,  and the transfer for the
               benefit of electric rate payers in Zone J of revenues that exceed
               the cost of service,  is not an establishment of "cost of service
               regulation"  and provides no recourse for  obtaining any revenues
               for electric ratepayers in Zone J.

          (e)  During the period that  revenues in excess of the cost of service
               are  directed to Zone J electric  ratepayers  as provided in this
               subsection,  National Grid will  implement the following  bidding
               protocols:

                    i.   Capacity will be bid at zero;

                    ii.  Energy  will be bid at the lower of  marginal  costs or
                         the NYISO reference price for the unit;

                    iii. Ancillary services will be bid at the lower of marginal
                         costs or the otherwise  applicable bid or price cap for
                         the unit.

     (8)  National  Grid will  provide  Staff  with  draft  and final  documents
          related to and will apprise Staff from time to time of the progress of
          all  offerings  described  above  (all  activities  in  "(2)"  above).
          National  Grid will  retain all offers and other  communications  from
          bidders and other potential  counterparties  for a minimum of one year
          after  National  Grid's  filing for  approval  of any  divestiture  or
          alternative   backstop  long-term   bilateral  physical  or  financial
          contract  (minimum  15 years)  for all of the  products  of the entire
          Ravenswood Station.

B.   Other Commitments

     1. For the  period  prior  to the  divestiture  of  Ravenswood  Station  in
accordance with Section 3(a) or the implementation of the alternative long-terms
bilateral physical or financial contract pursuant to Section 3(b):

          (a)  National  Grid agrees to continue  to examine the  necessity  and
     practicality of building  regulated  transmission  projects.  Additionally,
     National Grid in collaboration with Con Edison,  will perform,  or agree to
     perform,  a  feasibility  study and  stands  ready to enter into good faith
     negotiations with Con Edison and other interested parties to determine fair
     and reasonable recovery and allocation of costs if either or both utilities
     propose the New Scotland to Pleasant Valley  Reconstruction and Sprainbrook
     to Rainey 345 kV transmission project.


                                       12



          (b) National Grid will continue to vote in the transmission segment in
     the NYISO  stakeholder  process,  and will vote on market rules in a manner
     designed  to  further  the  interests  of  its  electric  transmission  and
     distribution customers.

          (c) National Grid agrees to complete within 180 days of the closing of
     the  KeySpan  merger,  a  repowering  study  of the  Ravenswood  Generating
     Station,  particularly  investigating  the feasibility of retiring Units 10
     and 20,  which have a total of 750 MWs of steam  generating  capacity,  and
     replacing  them with new combined  cycle  generation  having  equivalent or
     greater capacity.

          (d)  Immediately  after  closing of the merger,  National Grid will be
     willing to enter  into good faith  negotiations  with  Consolidated  Edison
     Company of New York,  Inc.  (Con Edison) to the end of supplying Con Edison
     with a source of  economical  steam for resale to its steam  customers  and
     enabling  Con Edison to retire  the "A" House  steam  plant  located at the
     Ravenswood site.

     2. Unless modified by the Commission:

          (a)  National  Grid  will  not own or  develop  additional  generation
     facilities in New York State unless specifically  requested by LIPA or NYPA
     under a long term contract,  or unless such ownership or development occurs
     as a result of repowering its existing generation facilities.

          (b) National  Grid will not execute any new financial  swaps  (forward
     purchases of capacity) of any amount in Zone J. Financial sales of capacity
     equal to no more  than  the  total  available  capacity  at the  Ravenswood
     Station will be allowed.

          (c)  National  Grid  will  continue  to be bound  by the  Commission's
     vertical market power guidelines in any follow-on  transactions in New York
     State. If at any time it appears that any generation  facilities  currently
     under long term  contract to NYPA or LIPA will no longer be under long term
     contract to NYPA or LIPA due to contract expiration or otherwise,  National
     Grid will prepare and file with the  Commission  an analysis  demonstrating
     how its continued ownership of such generation  facilities conforms or does
     not conform with the Commission's vertical market power guidelines,  and if
     necessary, identifying conditions under which such ownership could conform.

          (d) KeySpan  (pre-closing) and National Grid (post-closing) agree that
     they each will respectively  work  cooperatively and in good faith with the
     City of New York and other parties to resolve  expeditiously issues pending
     at the Federal Energy Regulatory Commission surrounding the capacity (UCAP)
     market in New York City (NYISO Zone J).


                                       13



IX.  KEDNY RATE PLAN

A. Overall Revenue Requirement

     If the merger is  consummated,  the  Signatory  Parties  have  agreed  upon
expense  and revenue  adjustments  to the KEDNY Rate Filing to be allowed as the
basis for calculating  revenue  requirement,  and a calculation of KEDNY revenue
requirement to be allowed as the basis for setting  rates,  the results of which
are set forth in  "Appendix  2"  attached  hereto  and made a part of this Joint
Proposal.  The calculation of revenue requirement  indicates no increase in base
KEDNY Gas Delivery  Service  Rates for Rate Year One,  Rate Year Two,  Rate Year
Three, Rate Year Four or Rate Year Five. The calculation of revenue requirement,
based  on  estimated  gas  costs,  indicates  an  increase  in  costs in the gas
adjustment  clause (GAC) of $26.7  million for Rate Year One, with no additional
increases,  other than minor inflationary increases  (approximately $300,000 per
year) on costs transferred to the GAC as part of rate unbundling,  indicated for
Rate  Year  Two,   Rate  Year   Three,   Rate  Year  Four  or  Rate  Year  Five.
Commodity-related  uncollectible  expense,  purchased  gas  working  capital and
return on gas in storage will be assigned  fixed  factors and will  reconcile to
actual gas costs. In addition,  one hundred percent of net savings (savings less
cost to achieve)  KEDNY  attains in its  combined  gas  resource  portfolio as a
result of the merger will flow to KEDNY gas commodity customers through the GAC.
KEDNY Gas Delivery Service revenue  requirement will remain frozen at the levels
reflected in Appendix 2 through the five rate years and  thereafter  through the
end of the Rate Period of this Joint  Proposal,  without  adjustment up or down,
except as  specifically  set forth in this Joint  Proposal.  Except as otherwise
provided  in this Joint  Proposal,  KEDNY  will not file new  tariff  leaves for
existing  services  designed  to produce  additional  annual  revenues to become
effective  prior to January 1, 2013.  KEDNY shall be allowed to file tariffs for
new services.

B. Merger Synergy Savings and Costs to Achieve

     The  calculation  of revenue  requirement in Section IX.A reflects the flow
through of 50 percent of the net synergy  savings  allocable to KEDNY as a share
of $156 million of estimated  annual mature  synergy  savings on the KeySpan and
National  Grid systems over the first five years of the merger,  which  excludes


                                       14



efficiency  gains that could occur without the merger and gas commodity  savings
which will flow to ratepayers  through the various gas adjustment  clauses.  100
percent of efficiency  gains  applicable to KEDNY have been reflected  directly.
Following the  termination  of the Rate Period,  KEDNY's cost of service will be
based on its  costs,  which will  reflect  100  percent of KEDNY's  share of any
synergy savings from the merger.

     The net  synergy  savings  also  reflect  the flow  through of the costs to
achieve these synergy savings  allocable to KEDNY as a share of the levelization
of $398  million in costs to achieve  based on an approach  using a 7.58 percent
return.  This synergy savings amount excludes  executive  benefits,  capitalized
information   technology  costs,  and  the  costs  to  achieve  associated  with
efficiency gains. KEDNY shall be authorized to include the annual  amortizations
of its  allocation  of the $398 million of costs to achieve in years six through
ten in the  event  that it  adjusts  its base  delivery  rates  in those  years.
Individual  components  of the $398 million  costs to achieve,  the annual gross
synergy  savings  over the first five years of the rate plan and the  allocation
factor used to develop  KEDNY's share of the net synergy savings are included in
Appendix 6 attached hereto and made a part of this Joint  Proposal.  KEDNY shall
also  record  separately  its  costs to  achieve  associated  with the  National
Grid/KeySpan  merger in a separate work order, and exclude any of these costs to
achieve  other than the agreed  upon  allowance  from its future cost of service
filings.

C. Adjustability

     No  adjustments,  reconciliations  or deferrals shall be allowed during the
Rate Period except as set forth in this Joint Proposal, as determined in another
phase of these proceedings, or as authorized by the Commission.

     For each rate year,  KEDNY will reconcile the following  costs recovered in
base  KEDNY Gas  Delivery  Service  Rates to the  levels  set forth  below.  All
deferred  amounts will be reflected in the existing KEDNY Balancing  Account and
recovered  from  customers or credited to customers  after the expiration of the
KEDNY Rate Period in a manner to be determined by the Commission.

     1.   Pensions and Other Post Employment Benefits ("OPEB")
          ----------------------------------------------------

     On the first day of Rate Year One,  KEDNY will  return to the  Commission's
Statement  of Policy for Pensions  and OPEBs,  issued  September 7, 1993 in Case
91-M-0980,  and will  reconcile  its  actual  pension  and OPEB  expense  to the
Estimated  Pension  and  OPEB  Expense  shown  below   (millions).   Fair  value


                                       15



adjustments  to the  Pension and OPEB plans made in  connection  with the merger
shall be amortized over ten years in accordance with the Statement of Policy and
reflected  in the  reconciliation  of actual  pension  and OPEB  expense  to the
Estimated  Pension  and OPEB  Expense.  Settlement  and  curtailment  costs from
merger-related programs for KEDNY, which are included in costs to achieve, shall
be  excluded  from the  pension  and OPEB  reconciliation.  In  addition  to the
reconciliation,  KEDNY will reduce the annual revenue  requirement by $6 million
for the five Rate Years as payment for returning to the pension policy. This $30
million together with the $99 million reduction in revenue requirements over the
five rate years shall be recorded as a regulatory  liability and amortized  over
the five rate years to match the  adjustments  to the cost of  service  shown in
Appendix 2 and fund KEDNY's  Pension/OPEB plans in Rate Year One by $60 million,
less the funding that KEDNY has made since March 31,  2007.  The benefit of this
funding  shall inure only to KEDNY  ratepayers.  As part of this Joint  Proposal
KEDNY  agrees  to  participate  in a study to  determine  what  the  appropriate
starting  deferral balance as of September 30, 1996,  should be when KEDNY is on
the policy statement.

                           Pension Expense                    OPEB Expense
                           ---------------                    ------------
         Rate Year One        $13.766                            $17.178
         Rate Year Two        $14.151                            $17.659
         Rate Year Three      $14.547                            $18.154
         Rate Year Four       $14.9545                           $18.6625
         Rate Year Five       $15.3735                           $19.1855

Subsequent  years will be  reconciled  to  $15.3735  million  for  Pensions  and
$19.1855 million for OPEBs.

     2.   Property and Special Franchise Taxes
          ------------------------------------

     KEDNY will defer 90% of the  difference  between  its actual  property  and
special franchise taxes and the following amounts (millions):

                  Rate Year One     -        $119.709
                  Rate Year Two     -        $125.694
                  Rate Year Three   -        $131.979
                  Rate Year Four    -        $138.578
                  Rate Year Five    -        $145.507


                                       16



     Subsequent  years will be  reconciled  for property  and special  franchise
taxes to $145.507 million.  If KEDNY is successful in obtaining tax refunds,  it
will have the right to petition the  Commission to share in such refunds.  Other
parties may take any position concerning any Petition filed by KEDNY.

     3.   SIR Costs
          ---------

     Subject to the cost sharing incentive mechanism described below, this Joint
Proposal provides for the  reconciliation or "true-up" of 100% of KEDNY's actual
SIR costs.  The base KEDNY Gas Delivery  Service Rates  established  pursuant to
this Joint  Proposal  reflect the annual  amortization  of $2.787 million of SIR
costs  which will  increase  by $3.186  million in Rate Year Four to reflect the
shift of the KEDNY merger expense amortization to SIR cost category.

     KEDNY will be  permitted  to retain 10% of any  recovery  of SIR costs from
insurance carriers and/or other potentially responsible parties, net of costs to
recover such as, attorney fees,  expert and consultant  fees.  KEDNY will pursue
such recoveries  aggressively and will credit 90% of such net recoveries against
its SIR cost balance.

     In the event that KEDNY  disposes of any property upon which  investigation
and  remediation  activities  have  occurred,  it will  credit  after-tax  gains
resulting from such disposition to the total SIR cost for the specific site.

     For any SIR activity  engaged in by KEDNY  following the effective  date of
the  rates  established  in  this  proceeding,  KEDNY  agrees,  subject  to  the
Department of Environmental Conservation's (DEC) determination of the nature and
scope of the SIR Activity, to consult with Staff and any other interested party,
including the City of New York, in order to establish a reasonable targeted cost
level for each separate phase of the SIR Activity on any particular site.

     Notwithstanding  the above  provisions the parties hereto  acknowledge that
(i) the DEC has primary  jurisdiction  over the  activities  of KEDNY in its SIR
activity,  with  the  Department  of  Health  (DOH)  having  responsibility  for
supporting  the  DEC in the  assessment  of  health  risk  associated  with  SIR
activities;  (ii) in the exercise of its jurisdiction over KEDNY's SIR Activity,
the DEC provides various forums and other  opportunities for interested  parties
to comment on and  participate  in, the  process of  identifying  potential  SIR
sites,  investigating  such  sites,  and  if  necessary,  determining  the  most
appropriate methods,  timing, and objectives of remediation;  (iii) that nothing
in this Joint  Proposal is intended to or  infringes on the rights of DEC or DOH
in the exercise of their respective jurisdiction, or on the rights of interested
parties to comment on and participate in the DEC processes described above.

               -----------------------

     The  projected  level  of  City/State  Construction  expenditures,  net  of
reimbursements,  for calendar year 2008, 2009, 2010, 2011, and 2012 is set forth
in Appendix 2, page 21. To the extent that KEDNY's actual  capital  spending for
City/State  construction net of reimbursements differs from the amount set forth
in Appendix 2, page 21, in any calendar year,  KEDNY will defer to the Balancing
Account the full revenue  requirement effect associated with the difference.  If
KEDNY's actual City/State  construction  expenditures exceed the level set forth
in Appendix 2, page 21, by more than 20 percent  then KEDNY shall have the right
to defer  following  a filing  with the  Director of  Accounting,  Finance,  and
Economics  that  demonstrates  that  amounts  were  reasonable  and  beyond  the
Company's control. Any disagreement associated with the filing shall be referred
to the Commission for decision.

          ii.  Non-Growth-Related Capital
               --------------------------

     If at the end of any calendar year 2008 through 2012,  KEDNY has spent less
than the amount  forecasted in the  categories of Non-Growth , LNG  Liquefaction
System, and Information Technology,  Facilities,  and Other Capital Expenditures
set forth on Appendix 2, page 21, KEDNY will defer the full revenue  requirement
effect of any shortfall for each category to its Balancing Account. For purposes
of this  provision,  the Growth  Capital  category  is  excluded  and limited to
capital costs for local main extensions, services and meters.

     5.   Exogenous Costs
          ---------------

     One hundred percent of all Exogenous Costs (including any credits) shall be
deferred and reflected in the KEDNY Balancing  Account.  "Exogenous Costs" means
all  of  the  incremental  effects  on  KEDNY's  costs,   revenues,  or  revenue
requirements  above or below the amounts set forth in Appendix 2 associated with
or caused by:

     (i)  any externally imposed accounting change;

     (ii) any change in the Federal, state or local rates, laws, regulations, or
          precedents governing income, revenue, sales, or franchise taxes; or

     (iii) any legislative,  court, or regulatory  change,  which imposes new or
           modifies existing obligations or duties.


                                       18



If these  Exogenous  Costs  individually in any one Rate Year ending December 31
exceed three  percent (3%) of KEDNY's  pre-tax  utility  income  (determined  in
accordance  with the  methodology  set forth for  Earnings  Sharing in the KEDNY
Merger  Rate  Plan) for the year in which the  change  first  occurs,  the total
impact of the Exogenous Costs will be included in the Balancing Account pursuant
to this section.  In the event that  exogenous  costs are incurred,  KEDNY shall
file a letter with the Director of Accounting,  Finance,  and Economics  setting
forth the  rational  for the  deferral  and its  calculation.  Any  disagreement
associated with the filing shall be referred to the Commission for a decision.

     6.   Additional Deferrals
          --------------------

     Nothing in this  Joint  Proposal  shall  preclude  KEDNY from  implementing
additional  deferrals as the result of the  resolution of Reserved  Issues or if
otherwise approved by the Commission.

     7.   Limitation on Deferrals
          -----------------------

     When  calculating  the level of earned  common  equity  return  that may be
subject  to sharing  under  Section  IX.E of this  Proposal,  KEDNY will  reduce
expenses  (debits) deferred for later recovery pursuant to the Proposal by up to
50% of the  total  deferral  in any Rate  Year,  provided,  however,  that  such
reduction in deferrals  will not cause the resulting  earnings to decrease below
11.3%,  and provided further that deferrals of SIR costs,  deferrals  associated
with incentives,  deferrals  associated with amounts  recovered  through the GAC
and/or  TAC,  deferred  DSM  costs,  deferred  Pension  and OPEB  expenses,  and
deferrals of the revenue  requirements  associated with City/State  Construction
expenditures will be excluded from this deferral limitation provision.

D. Other Provisions

     1.   Temperature Controlled and Interruptible Services
          -------------------------------------------------

     Temperature  Controlled  Service and  Interruptible  Service will remain as
distinct  service  classifications.   However,  the  terms  of  the  Temperature
Controlled  Service  Classification  will be modified to include an annual price
cap that equals the annual  revenue,  including  all  surcharges,  that would be
derived from providing  service to such customers  under S.C. No. 2. The monthly
price cap will be removed from the tariff for the Temperature Controlled Service
Classification.    In   addition,   KEDNY's   Temperature   Controlled   Service
Classification  will be changed so that the  allocation of gas demand charges to
Temperature  Controlled Sales customers will increase from $.10/dth to $.46/dth.
KEDNY will  credit all such  allocated  demand  charges  paid to firm  customers
through the GAC.


                                       19



E. Earnings Sharing

     Following each of the five rate years, KEDNY will make a computation of its
gas rate of return on common equity capital (ROE) for the  applicable  preceding
rate year  utilizing a capital  structure with an equity  component  equal to 45
percent.  In the event of a  Stayout,  KEDNY will make the  computation  for any
subsequent  twelve-month  period  during  which the Stayout was in effect for at
least a portion of the twelve-month  period. The computations and the underlying
data  will be made  available  to the  Signatory  Parties  and  filed  with  the
Commission  not  later  than  150  days  following  the  end of  the  applicable
twelve-month period. The filings will include supporting  workpapers and the ROE
calculation  based  on  traditional   ratemaking   practices  and  methodologies
applicable to KEDNY as to includable  costs,  revenues and  appropriate  capital
structure.  The  computation  of ROE will be  calculated  from KEDNY's  books of
account for the applicable twelve-month period, except that:

     (a) KEDNY's  rate base shall not include any goodwill  associated  with the
     National Grid/KeySpan merger,

     (b) KEDNY's  return shall  exclude the effects of discrete  incentives,  if
     any,  as may be  applied  as a  result  of this or  another  phase of these
     proceedings,

     (c) KEDNY's operating  expenses shall reflect the levelized cost to achieve
     and synergy  savings  shown on page 1 of Appendix 6 such that 50 percent of
     the levelized net synergy  savings (i.e.,  line 13 of page 1 of Appendix 6)
     shall be excluded from the earnings  calculation.  This  provision will not
     extend in the event of a Stayout.

     (d) KEDNY's  return shall exclude the effect of any costs to achieve merger
     savings, which are associated with executive benefits,

     (e) KEDNY shall include the annual amortization of the regulatory liability
     associated  with any margin  revenues that are not realized in actual sales
     to customers and are being  amortized over the five Rate Years to match the
     adjustments to the cost of service shown in Appendix 2,

     (f) KEDNY shall  include in the  earnings  sharing  calculation  the annual
     amortization of the regulatory  liability associated with the company's buy
     back and return to the Commission's Pension and OPEB Policy Statement, and


                                       20



     (g) KEDNY's return shall exclude  revenue  adjustments  due to prior period
     over- or under-revenue recoveries related to revenue decoupling mechanisms.

     If the level of earned  common  equity return in any rate year exceeds 10.5
percent ("Earnings Sharing  Threshold"),  the amount in excess of 10.5% shall be
deemed "Shared  Earnings" for the purposes of this Joint Proposal.  In the event
of a Stayout, the earnings sharing provisions will continue for the Rate period,
to be applied,  if  necessary,  on a pro-rata  basis based on monthly  operating
revenues.  The  customers'  share of any  earnings  will be  credited to KEDNY's
Balancing  Account for the benefit of customers.  For each  twelve-month  period
covered by this Joint  Proposal,  KEDNY will allocate the revenue  equivalent of
its earned common equity return,  if any, in excess of the 10.5 percent Earnings
Sharing Threshold as follows:

     (a)  for the first 200 basis points above the  Earnings  Sharing  Threshold
          (i.e.  >10.5% - 12.5%),  50% of the revenue  equivalent  of any Shared
          Earnings  will  be  deferred  for the  benefit  of  customers  and the
          remaining 50% will be retained by KEDNY;

     (b)  for the next 100 basis  points above the  Earnings  Sharing  Threshold
          (i.e.  >12.5% to 13.5%),  65% of the revenue  equivalent of the Shared
          Earnings will be deferred for the benefit of customers and 35% will be
          retained by KEDNY; and

     (c)  all  Shared  Earnings  in excess  of 13.5%  will be  deferred  for the
          benefit of customers.

     Pursuant to another phase of these proceedings,  the Signatory Parties will
collaborate to establish certain targets  associated with the implementation and
operation of demand side  management  programs.  In the event that these targets
are  met  in  any  applicable  twelve-month  period,  KEDNY's  Earnings  Sharing
Threshold and all other earnings sharing thresholds as identified above shall be
adjusted upward by 10 basis points for the applicable  twelve-month  period,  as
follows:

     (a)  for the first 200 basis points above the  Earnings  Sharing  Threshold
          (i.e.  >10.6% - 12.6%),  50% of the revenue  equivalent  of any Shared
          Earnings  will  be  deferred  for the  benefit  of  customers  and the
          remaining 50% will be retained by KEDNY;

     (b)  for the next 100 basis  points above the  Earnings  Sharing  Threshold
          (i.e.  >12.6% to 13.6%),  65% of the revenue  equivalent of the Shared
          Earnings will be deferred for the benefit of customers and 35% will be
          retained by KEDNY; and

     (c)  all  Shared  Earnings  in excess  of 13.6%  will be  deferred  for the
          benefit of customers.


                                       21



X.   KEDLI RATE PLAN

A. Overall Revenue Requirement

     If the merger is  consummated,  the  Signatory  Parties  have  agreed  upon
expense  and revenue  adjustments  to the KEDLI Rate Filing to be allowed as the
basis for calculating  revenue  requirement,  and a calculation of KEDLI revenue
requirement to be allowed as the basis for setting  rates,  the results of which
are set forth in  "Appendix  3"  attached  hereto  and made a part of this Joint
Proposal.  The calculation of revenue  requirement  indicates an increase of $60
million  in base KEDLI Gas  Delivery  Service  Rates for Rate Year One,  with no
additional  increases  indicated for Rate Year Two,  Rate Year Three,  Rate Year
Four or Rate  Year  Five.  The  calculation  of  revenue  requirement,  based on
estimated gas costs, indicates an increase in costs in the gas adjustment clause
(GAC) of $12.5 million for Rate Year One, with no  additional  increases,  other
than minor  inflationary  increases  (approximately  $90,000  per year) on costs
transferred to the GAC as part of rate unbundling,  indicated for Rate Year Two,
Rate  Year  Three,   Rate  Year  Four  or  Rate  Year  Five.   Commodity-related
uncollectible  expense,  purchased  gas  working  capital  and  return on gas in
storage will be assigned  fixed factors and will  reconcile to actual gas costs.
In addition,  one hundred percent of net savings  (savings less cost to achieve)
KEDLI  attains in its combined gas resource  portfolio as a result of the merger
will flow to KEDLI gas commodity  customers  through the GAC. KEDLI Gas Delivery
Service  revenue  requirement  will  remain  frozen at the levels  reflected  in
Appendix 2 through  the five rate years and  thereafter  through  the end of the
Rate Period of this Joint  Proposal,  without  adjustment up or down,  except as
specifically set forth in this Joint Proposal.  Except as otherwise  provided in
this Joint Proposal, KEDLI will not file new tariff leaves for existing services
designed to produce  additional  annual  revenues to become  effective  prior to
January 1, 2013. KEDLI shall be allowed to file tariffs for new services.

B. Merger Synergy Savings and Costs to Achieve

     The  calculation  of revenue  requirement  in Section X.A reflects the flow
through of 50 percent of the net synergy  savings  allocable to KEDLI as a share
of $156 million of estimated  annual mature  synergy  savings on the KeySpan and
National  Grid systems over the first five years of the merger,  which  excludes
efficiency  gains that could occur without the merger and gas commodity  savings


                                       22



which will flow to ratepayers  through the various gas adjustment  clauses.  100
percent of efficiency  gains  applicable to KEDLI have been reflected  directly.
Following the  termination  of the Rate Period,  KEDLI's cost of service will be
based on its  costs,  which will  reflect  100  percent of KEDLI's  share of any
synergy savings from the merger.  The net synergy savings also reflects the flow
through of the costs to achieve  these synergy  savings  allocable to KEDLI as a
share of the  levelization  of $398  million  in costs  to  achieve  based on an
approach using an 8.39 percent  return.  This synergy  savings  amount  excludes
executive benefits,  capitalized  information technology costs, and the costs to
achieve  associated with efficiency gains.  KEDLI shall be authorized to include
the  annual  amortizations  of its  allocation  of the $398  million of costs to
achieve in years six through ten in the event that it adjusts its base  delivery
rates  in those  years.  Individual  components  of the  $398  million  costs to
achieve,  the annual gross synergy savings over the first five years of the rate
plan and the allocation  factor used to develop KEDLI's share of the net synergy
savings are included in Appendix 6 attached hereto and made a part of this Joint
Proposal.  KEDLI shall also record  separately  its costs to achieve  associated
with the National  Grid/KeySpan merger in a separate work order, and exclude any
of these costs to achieve other than the agreed upon  allowance  from its future
cost of service filings.

C. Adjustability

     No  adjustments,  reconciliations  or deferrals shall be allowed during the
Rate Period except as set forth in this Joint Proposal, as determined in another
phase of these proceedings, or as authorized by the Commission.

     For each Rate Year KEDLI will  reconcile the following  costs  recovered in
base  KEDLI Gas  Delivery  Service  Rates to the  levels  set forth  below.  All
deferred  amounts will be reflected in the existing KEDLI Balancing  Account and
recovered  from  customers or credited to customers  after the expiration of the
KEDLI Rate Period in a manner to be determined by the Commission.

     1.   Pensions and Other Post Employment Benefits ("OPEB")
          ----------------------------------------------------

     KEDLI will  reconcile its actual  pension and OPEB expense to the Estimated
Pension and OPEB Expense shown below  (millions).  Fair value adjustments to the
Pension and OPEB plans made in  connection  with the merger  shall be  amortized
over ten years in  accordance  with the Statement of Policy and reflected in the
reconciliation  of actual pension and OPEB expense to the Estimated  Pension and
OPEB Expense.  Settlement and curtailment costs from merger-related programs for


                                       23



KEDLI,  which are  included  in costs to  achieve,  shall be  excluded  from the
pension and OPEB reconciliation. As part of this Joint Proposal, KEDLI agrees to
participate in a study to determine what the appropriate deferral balance should
be at the start of the rate plan.

                           Pension Expense                     OPEB Expense
                           ---------------                     ------------
         Rate Year One        $10.084                            $12.413
         Rate Year Two        $10.367                            $12.761
         Rate Year Three      $10.657                            $13.118
         Rate Year Four       $10.955                            $13.485
         Rate Year Five       $11.262                            $13.863

Subsequent  years will be reconciled to $11.262 million for Pensions and $13.863
million for OPEBs.

     2.   Property and Special Franchise Taxes
          ------------------------------------

     KEDLI will defer 90% of the  difference  between  its actual  property  and
special franchise taxes and the following amounts (millions):

                  Rate Year One     -        $97.610
                  Rate Year Two     -        $102.491
                  Rate Year Three   -        $107.615
                  Rate Year Four    -        $112.996
                  Rate Year Five    -        $118.646

Subsequent years will be reconciled for property and special  franchise taxes to
$118.646 million.

     If KEDLI is successful in obtaining tax refunds,  it will have the right to
petition the  Commission  to share in such  refunds.  Other parties may take any
position concerning any Petition filed by KEDLI.

     The above  reconciliation  excludes  all refunds  associated  with  KEDLI's
ongoing  litigation  with Nassau County over its prior  assessments  of property
taxes in Index Nos. 011695-97,  011440-99, which are pending before the New York
Supreme Court, Nassau County ("Nassau County Litigation"). KEDLI will retain all
refunds or prospective  reductions in property taxes that it may receive through
litigation or settlement of the Nassau County  litigation  even if those refunds
or reductions occur after the Rate Plan period. Accordingly, for the purposes of


                                       24



16 NYCRR  ss.89.3,  the  Signatory  Parties  agree  that 100  percent of the tax
refunds or prospective reductions would be retained by KEDLI and not distributed
to its  customers.  Nothing  in this  Merger  Joint  Proposal  shall  in any way
restrict  the ability of KEDLI to settle this  property  tax dispute with Nassau
County or affect the form of that settlement.  The Signatory  Parties  stipulate
that by approving  this Joint  Proposal the  Commission  is neither  determining
liability nor the amount of damages in the Nassau County Litigation. Rather, the
resolution in this Joint Proposal is for rate making purposes only and shall not
prejudice any party in the ongoing Nassau County Litigation.

     3.   SIR Costs
          ---------

     Subject to the cost sharing incentive mechanism described below, this Joint
Proposal provides for the  reconciliation or "true-up" of 100% of KEDLI's actual
SIR costs.  The base KEDLI Gas Delivery  Service Rates  established  pursuant to
this Joint  Proposal  reflect the annual  amortization  of $2.444 million of SIR
costs which will  increase by $657,000 in Rate Year Four to reflect the shift of
the KEDLI merger expense amortization to SIR cost category.

     KEDLI will be  permitted  to retain 10% of any  recovery  of SIR costs from
insurance carriers and/or other potentially responsible parties, net of costs to
recover such as, attorney fees,  expert and consultant  fees.  KEDLI will pursue
such recoveries  aggressively and will credit 90% of such net recoveries against
its SIR cost balance.

     In the event that KEDLI  disposes of any property upon which  investigation
and  remediation  activities  have  occurred,  it will  credit  after-tax  gains
resulting from such disposition to the total SIR cost for the specific site.

     For any SIR activity  engaged in by KEDLI  following the effective  date of
the  rates  established  in  this  proceeding,  KEDLI  agrees,  subject  to  the
Department of Environmental Conservation's (DEC) determination of the nature and
scope of the SIR Activity, to consult with Staff and any other interested party,
including the Suffolk and Nassau  Counties and the City of New York, in order to
establish a reasonable  targeted cost level for each  separate  phase of the SIR
Activity on any particular site.

     Notwithstanding  the above  provisions the parties hereto  acknowledge that
(i) the DEC has primary  jurisdiction  over the  activities  of KEDLI in its SIR
activity,  with  the  Department  of  Health  (DOH)  having  responsibility  for
supporting  the  DEC in the  assessment  of  health  risk  associated  with  SIR
activities;  (ii) in the exercise of its jurisdiction over KEDLI's SIR Activity,


                                       25



the DEC provides various forums and other  opportunities for interested  parties
to comment on and  participate  in, the  process of  identifying  potential  SIR
sites,  investigating  such  sites,  and  if  necessary,  determining  the  most
appropriate methods,  timing, and objectives of remediation;  (iii) that nothing
in this Joint  Proposal is intended to or  infringes on the rights of DEC or DOH
in the exercise of their respective jurisdiction, or on the rights of interested
parties to comment on and participate in the DEC processes described above.

     4.   Capital Tracker
          ---------------

          i.   City/State Construction
               -----------------------

     The  projected  level  of  City/State  Construction  expenditures,  net  of
reimbursements,  for calendar year 2008, 2009, 2010, 2011, and 2012 is set forth
on Appendix 3, page 21. To the extent that KEDLI's actual  capital  spending for
City/State  construction,  net of  reimbursements,  differs  from the amount set
forth in  Appendix  3, page 21, by more than 20  percent in any  calendar  year,
KEDLI will defer to the Balancing  Account the full revenue  requirement  effect
associated  with the  difference.  If  KEDLI's  actual  City/State  construction
expenditures exceed the level set forth in Appendix 3, page 21, then KEDLI shall
have the right to defer  following  a filing with the  Director  of  Accounting,
Finance, and Economics that demonstrates that amounts were reasonable and beyond
the Company's  control.  Any  disagreement  associated  with the filing shall be
referred to the Commission for decision.

          ii.  Non-Growth-Related Capital
               --------------------------

     If at the end of any calendar year 2008 through 2012,  KEDLI has spent less
than the amount  forecasted  in the  categories  of  Non-Growth,  Islander  East
Alternative,   and  Information  Technology,   Facilities,   and  Other  Capital
Expenditures set forth on Appendix 3, page 21, KEDLI will defer the full revenue
requirement  effect of any shortfall for each category to its Balancing Account.
For  purposes of this  provision,  the Growth  Capital  category is excluded and
limited to capital costs for local main extensions, services and meters.

     With respect to capital  expenditures  associated  with its Pipeline Safety
Replacement  Program,  to the extent that KEDLI  underspends its budget for this
Program in any one year, it will be permitted to carry  forward such  unexpended
amount for future  calendar  years. If by the end of calendar year 2012 there is
still a carry forward  balance,  KEDLI will defer in the  Balancing  Account the
full revenue  requirement  associated  with the unspent balance from the year it
was not spent.


                                       26



     KEDLI's Gas Business Unit Capital forecast  includes $23 million of capital
expenditures  that are associated  with the  construction  of new and reinforced
facilities  required  to receive  additional  quantities  of gas on Long  Island
commencing  on  November  1, 2008.  The $23 million  capital  expenditure  level
assumes that these quantities will be delivered at South Commack by the Iroquois
pipeline.  In the event that the Islander East  pipeline  receives all necessary
approvals  to  commence  construction  in time to meet  the  in-service  date of
November  2008 such  additional  quantities  will be delivered to Long Island by
Islander East rather than by Iroquois.  If such event occurs,  KEDLI will advise
the  Commission  in  writing  and KEDLI  will be  permitted  to defer the actual
difference  between the full revenue  requirement effect associated with the $23
million  placeholder  amount  described above and the lesser of the full revenue
requirement  effect associated with the total construction cost of Islander East
or $46.9 million.

     5.   Exogenous Costs
          ---------------

     One hundred percent of all Exogenous Costs (including any credits) shall be
deferred and reflected in the KEDLI Balancing  Account.  "Exogenous Costs" means
all  of  the  incremental  effects  on  KEDLI's  costs,   revenues,  or  revenue
requirements  above or below the amounts set forth in Appendix 3 associated with
or caused by:

     (i)  any externally imposed accounting change;

     (ii) any change in the Federal, state or local rates, laws, regulations, or
          precedents governing income, revenue, sales, or franchise taxes; or

     (iii) any legislative,  court, or regulatory  change,  which imposes new or
          modifies existing obligations or duties.

If these  Exogenous  Costs  individually  or  collectively  in any one Rate Year
ending  December 31 exceed three percent (3%) of KEDLI's  pre-tax utility income
(determined in accordance with the methodology set forth for Earnings Sharing in
the KEDLI Merger Rate Plan) for the year in which the change first  occurs,  the
total impact of the Exogenous  Costs will be included in the  Balancing  Account
pursuant to this section. In the event that exogenous costs are incurred,  KEDLI
shall file a letter with the  Director of  Accounting,  Finance,  and  Economics
setting  forth  the  rational  for  the  deferral  and  its   calculation.   Any
disagreement  associated with the filing shall be referred to the Commission for
a decision.


                                       27



     6.   Additional Deferrals
          --------------------

     Nothing  in  this  Merger  Joint   Proposal   shall   preclude  KEDLI  from
implementing  additional  deferrals as the result of the  resolution of Reserved
Issues or if otherwise approved by the Commission.

     7.   Limitation on Deferrals
          -----------------------

     When  calculating  the level of earned  common  equity  return  that may be
subject  to sharing  under  Section  X.E of this  Proposal,  KEDLI  will  reduce
expenses  (debits) deferred for later recovery pursuant to the Proposal by up to
50% of the  total  deferral  in any Rate  Year,  provided,  however,  that  such
reduction in deferrals  will not cause the resulting  earnings to decrease below
11.3%,  and provided further that deferrals of SIR costs,  deferrals  associated
with incentives,  deferrals  associated with amounts  recovered  through the GAC
and/or  TAC,  deferred  DSM  costs,  deferred  Pension  and OPEB  expenses,  and
deferrals of the revenue requirements associated with City/State Construction or
other  specific  capital  expenditures  identified in Section 4 will be excluded
from this deferral limitation provision. D. Other Provisions

     1.   Temperature Controlled and Interruptible Services
          -------------------------------------------------

     Temperature  Controlled  Service and  Interruptible  Service will remain as
distinct  service  classifications.   However,  the  terms  of  the  Temperature
Controlled  Service  Classification  will be modified to include an annual price
cap to equal the annual revenue, including all surcharges, that would be derived
from providing service to such customers under S.C. No. 2. The monthly price cap
will  be  removed  from  the  tariff  for  the  Temperature  Controlled  Service
Classification.    In   addition,   KEDLI's   Temperature   Controlled   Service
Classification  will be changed so that the  allocation of gas demand charges to
Temperature  Controlled Sales customers will increase from $.10/dth to $.46/dth.
KEDLI will  credit all such  allocated  demand  charges  paid to firm  customers
through the GAC.

E. Earnings Sharing

     Following each of the five rate years, KEDLI will make a computation of its
gas rate of return on common equity capital (ROE) for the  applicable  preceding
rate year  utilizing a capital  structure with an equity  component  equal to 45
percent.  In the event of a  Stayout,  KEDLI will make the  computation  for any
subsequent  twelve-month  period  during  which the Stayout was in effect for at
least a portion of the twelve-month  period. The computations and the underlying


                                       28



data  will be made  available  to the  Signatory  Parties  and  filed  with  the
Commission  not  later  than  150  days  following  the  end of  the  applicable
twelve-month period. The filings will include supporting  workpapers and the ROE
calculation  based  on  traditional   ratemaking   practices  and  methodologies
applicable to KEDLI as to includable  costs,  revenues and  appropriate  capital
structure.  The  computation  of ROE will be  calculated  from KEDLI's  books of
account for the applicable twelve-month period, except that:

     (a) KEDLI's  rate base shall not include any goodwill  associated  with the
     National Grid/KeySpan merger,

     (b) KEDLI's  return shall  exclude the effects of discrete  incentives,  if
     any,  as may be  applied  as a  result  of this or  another  phase of these
     proceedings,

     (c) KEDLI's operating  expenses shall reflect the levelized cost to achieve
     and synergy  savings  shown on page 1 of Appendix 6 such that 50 percent of
     the levelized net synergy  savings (i.e.,  line 26 of page 1 of Appendix 6)
     shall be excluded from the earnings  calculation.  This  provision will not
     extend in the event of a Stayout.

     (d) KEDLI's  return shall exclude the effect of any costs to achieve merger
     savings associated with executive benefits,

     (e) KEDLI shall include the annual amortization of the regulatory liability
     associated  with any margin  revenues that are not realized in actual sales
     to customers and are being  amortized over the five Rate Years to match the
     adjustments to the cost of service shown in Appendix 3, and

     (f) KEDLI's return shall exclude  revenue  adjustments  due to prior period
     over- or under-revenue recoveries related to revenue decoupling mechanisms.


     If the level of earned  common  equity return in any rate year exceeds 10.5
percent ("Earnings Sharing  Threshold"),  the amount in excess of 10.5% shall be
deemed "Shared  Earnings" for the purposes of this Joint Proposal.  In the event
of a Stayout, the earnings sharing provisions will continue for the Rate period,
to be applied,  if  necessary,  on a pro-rata  basis based on monthly  operating
revenues.  The  customers'  share of any  earnings  will be  credited to KEDLI's
Balancing  Account for the benefit of customers.  For each  twelve-month  period
covered by this Joint  Proposal,  KEDLI will allocate the revenue  equivalent of
its earned common equity return,  if any, in excess of the 10.5 percent Earnings
Sharing Threshold as follows:


                                       29



     (a)  for the first 200 basis points above the  Earnings  Sharing  Threshold
          (i.e.  >10.5% - 12.5%),  50% of the revenue  equivalent  of any Shared
          Earnings  will  be  deferred  for the  benefit  of  customers  and the
          remaining 50% will be retained by KEDLI;

     (b)  for the next 100 basis  points above the  Earnings  Sharing  Threshold
          (i.e.  >12.5% to 13.5%),  65% of the revenue  equivalent of the Shared
          Earnings will be deferred for the benefit of customers and 35% will be
          retained by KEDLI; and

     (c)  all  Shared  Earnings  in excess  of 13.5%  will be  deferred  for the
          benefit of customers.

     Pursuant to another phase of these proceedings,  the Signatory Parties will
collaborate to establish certain targets  associated with the implementation and
operation of demand side  management  programs.  In the event that these targets
are  met  in  any  applicable  twelve-month  period,  KEDLI's  Earnings  Sharing
Threshold and all other earnings sharing thresholds as identified above shall be
adjusted upward by 10 basis points for the applicable  twelve-month  period,  as
follows:

     (a)  for the first 200 basis points above the  Earnings  Sharing  Threshold
          (i.e.  >10.6% - 12.6%),  50% of the revenue  equivalent  of any Shared
          Earnings  will  be  deferred  for the  benefit  of  customers  and the
          remaining 50% will be retained by KEDLI;

     (b)  for the next 100 basis  points above the  Earnings  Sharing  Threshold
          (i.e.  >12.6% to 13.6%),  65% of the revenue  equivalent of the Shared
          Earnings will be deferred for the benefit of customers and 35% will be
          retained by KEDLI; and

     (c)  all  Shared  Earnings  in excess  of 13.6%  will be  deferred  for the
          benefit of customers.

XI.  PROVISIONS AFFECTING NIAGARA MOHAWK POWER CORPORATION

A. Merger Synergy Savings and Costs to Achieve

     In a separate filing to the  Commission,  Niagara Mohawk will provide for a
flow-through to its customers of a share of the net synergy savings allocable to
Niagara Mohawk in accordance with Attachment 10 to the Niagara Mohawk rate plan.

B. Accelerated Rate Credit

     In a separate rate filing made under its rate plan,  contemporaneously with
its next CTC reset filing for consideration by the parties in that case, Niagara
Mohawk will propose an alternative  one-month  credit of the net synergy savings
for balance of the Niagara Mohawk rate plan.


                                       30



C. Commitment to Increase Internal Company Staffing in Upstate New York

     1.   Transmission Staffing

          National  Grid shall  initially  implement a voluntary  program for at
     least  thirty  line  mechanics  and  thirty  electricians  to  work  in the
     Transmission  Group in Upstate New York with an opt-out that stays with the
     employee.   Any  line  mechanic  or  electrician  opting  to  work  in  the
     Transmission  Group will be  back-filled  one-for-one  in  distribution  in
     Niagara Mohawk's Service Territory.

     2.   Distribution Staffing

          In addition to the  backfilling  of  Distribution  Line  positions for
     transfers to the  Transmission  Group,  National Grid intends to maintain a
     staffing level of 700 positions in the Distribution Line Department located
     in  Niagara  Mohawk's  Service  Territory,  and  seek  to add at  least  30
     positions annually over the next three years.

         3.  Customer Service Staffing

          Regarding Customer Service,  incumbent  employees  currently occupying
     positions in the upstate New York Customer  Service Contact Centers will be
     maintained  through  2010.  National Grid will commit to operating one call
     center business in upstate New York through 2010, and possibly beyond, if a
     new and separate labor agreement can be reached. The agreement will provide
     maximum  flexibility to ensure the highest of quality standards,  including
     work  performance  metrics,  so that the center can  operate  competitively
     compared to the call center marketplace.

         4. Article VII Compliance Staffing

          National Grid shall implement the following  enhanced  procedures with
     respect to the  preparation  and  prosecution  of Article  VII and Part 102
     proceedings  for   transmission   projects  with  the  goal  of  processing
     efficiently  the Commission  filings for the  significant  level of capital
     projects and spending in Upstate New York:

          (a)  National  Grid  shall   organize  a   cross-functional   in-house
               Permitting  &  Licensing  Team  dedicated  to  Upstate  New  York
               projects,  which includes representatives from the Environmental,
               Project  Management,   Engineering,   Communications,  and  Legal
               functions.  This team shall be  supplemented  by the  addition of
               National Grid staff members  devoted to  engineering  and project
               management for New York projects;


                                       31



          (b)  the in-house  Permitting  & Licensing  Team shall be supported by
               recently  designated   engineering   consultants,   environmental
               consultants,  and New  York  counsel  that  may  include  outside
               counsel based in New York;

          (c)  National  Grid shall  implement  improved  quality  control  over
               consultant-produced  documents  prior to their  submission to the
               PSC; and

          (d)  National Grid shall hold periodic meetings and consultations with
               Staff,  in  which  Company  personnel  and its  consultants  will
               discuss  the  status  of  and  issues  associated  with  existing
               filings,  the upcoming  schedule for future  Article VII filings,
               and improvements that can be made to those filings or the process
               before the  Commission,  with the  objective of fully meeting the
               Staff's  and  Commission's  expectations  for those  filings  and
               process.

XII. PROVISIONS ASSOCIATED WITH LIPA AGREEMENT

A. Additional Benefits to Long Island Customers through LIPA Agreement

     Several provisions in the LIPA agreements represent significant  additional
value to several  Signatory  Parties that they believe support the  Commission's
public  interest  determination  in this  case.  Those  provisions  include  the
following:

          "5, Staffing of On-Island  Field Force and Storm Support.  Section 4.6
     of the  Amended and  Restated  MSA is amended to add a new  subsection  (D)
     thereto to read as follows:

               `Staffing of On-Island Field Force and Storm Support. The Manager
          shall  maintain an  appropriate  level of field  personnel (to include
          Electric  Design &  Construction,  Electric  Service,  Electric System
          Operations,   Substation  Maintenance,  and  Meter  &  Test  or  their
          successors  performing  similar  functions)  in  LIPA's  Service  Area
          reasonably necessary to satisfy the Manager's contractual  obligations
          under this Agreement and to meet the target performance levels for the
          Performance Metrics;  The Manager,  shall provide LIPA with reasonable
          advance  notice of any  proposed  changes  to the level of such  field
          personnel  in LIPA's  Service  Area in order to enable  LIPA to fairly
          consider  Manager's  proposed changes,  and the Manager shall consider
          LIPA's  concerns  before  making any changes to the staffing  level of
          such field  personnel that could be reasonably  expected to negatively
          impact service quality in LIPA's Service Area. In the event of a storm
          or other adverse operational condition, National Grid shall provide or
          cause to be provided field support,  logistics  support and mutual aid
          services from its other business units to support LIPA as if LIPA were
          an  Affiliate  of  National  Grid and, if  necessary,  shall cause its
          Affiliates to provide field support,  logistics support and mutual aid
          services to LIPA,  National  Grid shall  provide  LIPA with mutual aid
          services  in  accordance  with the terms and  conditions  of  National
          Grid's  Mutual  Assistance  Agreement,  then in  effect.  LIPA will be
          afforded  the  opportunity  to  consult  on any  proposed  changes  to
          National Grid's Mutual Assistance Agreement.


                                       32



          "6. Customer  Service Long Island Presence and Storm Support.  Section
     4.9 of the Amended and Restated MSA is amended to add a new  subsection (K)
     thereto to read as follows:

               "(K) Customer Service Long Island Presence and Storm Support. The
          Manager  shall  maintain  at all times  during the Term  hereof a call
          center on Long  Island,  sufficiently  staffed to handle  normal  call
          activity  (excluding credit and collections calls). The Manager agrees
          that  during  the Term  hereof it will not (1)  reduce  the  number of
          customer walk-in centers from those in existence on January 1, 2006 as
          well as the Far Rockaway  customer  walk-in  facility  without  LIPA's
          prior  written  approval,  (2) relocate any customer  walk-in  centers
          without LIPA's prior written approval (which LIPA may not unreasonably
          withhold),  or (3) outsource  meter reading or meter services  without
          LIPA's prior written  approval.  As provided in Section 4.6(D), in the
          event of a storm or other adverse operational condition, National Grid
          shall provide or cause to be provided customer service support to LIPA
          as if LIPA were an Affiliate of National Grid and, if necessary, shall
          cause its Affiliates to provide customer service support to LIPA."

(1)  The deferral mitigator also precludes  deferral and subsequent  recovery of
     special  franchise  property  tax for  KEDNY  between  October  1, 2007 and
     December 31, 2007.

     will need to consider the impact of the Additional Margin Adjustment.

              APPENDIX 4 - Corporate Structure and Affiliate Rules













Appendix 4: Corporate Structure and Affiliate Rules
- ---------------------------------------------------

     Effective on the closing of the merger,  National  Grid will  implement the
following  Corporate Structure and Affiliate Rules which will continue in effect
unless and until such time as the Commission authorizes an express change.

1. Definitions

     The following definitions apply to both Appendix 4 and Appendix 5.

     Corporate  and  Administrative  Services - means all services  performed by
KeySpan Corporate  Services LLC and KeySpan Utility Services LLC, as well as any
services performed by ServiceCo or not otherwise prohibited from being performed
by ServiceCo.  Corporate  and  Administrative  Services  will  include,  without
limitation,  all  administrative and office support for the benefit of US HoldCo
and any of its subsidiaries.

     Customer  Information  - means any of the  following  information  about an
individual  customer or any  aggregation  of individual  customers  collected or
compiled  by  KEDNY or  KEDLI:  name,  address,  telephone  number,  identifying
information,  consumption  history,  individual usage  characteristics,  payment
history, complaint history and the contents of any application for service.

     National Grid Other  Affiliates--  means  affiliates  of HoldCo,  including
affiliates  in the  United  States  and  throughout  the  world,  but  excluding
ServiceCo, KEDNY, KEDLI, Unregulated Competitive Energy Affiliates and Regulated
Affiliates.

     Personal  Property--means  any and all property that is not real  property,
including leases and all other property not deemed to be "real property."

     Regulated  Affiliates - means the subsidiaries (other than KEDNY and KEDLI)
of US HoldCo,  including  future  subsidiaries,  that  provide the full range of
regulated gas and/or electric transmission or distribution  services,  including
Niagara  Mohawk Power  Corporation,  New England  Power  Company,  Massachusetts
Electric  Company,  New England  Electric  Transmission  Corporation,  Nantucket
Electric  Company,  Granite State Electric  Company,  The Narragansett  Electric
Company,   Boston  Gas  Company,  Essex  Gas  Company,   Colonial  Gas  Company,
EnergyNorth Gas Company, New England Hydro-Transmission Corporation, New England
Hydro-Transmission Electric Company, Inc., and each of their successors, and any
affiliate to the extent that such affiliate  provides  services to LIPA pursuant
to the LIPA Agreements.


                                       1



     ServiceCo  -  means  National  Grid  USA  Service  Company,  Inc.,  KeySpan
Corporate  Services LLC, and/or KeySpan Utility  Services LLC, or any successors
thereto,  which provide a variety of  traditional  corporate and  administrative
services  for the  National  Grid USA system,  and to LIPA  pursuant to the LIPA
Agreements.

     System  Information - means  non-public  information  or data regarding the
operation of or capacity  constraints on and/or  expansion plans relating to the
energy delivery system of KEDNY or KEDLI.

     Unregulated  Affiliate - means any  affiliate  of HoldCo  other than KEDNY,
KEDLI, or any Regulated Affiliate.

     Unregulated Competitive Energy Affiliate - means any of US HoldCo's current
or  future  affiliates  that  directly  provides  competitive  electric  or  gas
commodity sales or service or heating, ventilation and air conditioning ("HVAC")
sales or service in New York State,  i.e.,  KeySpan Energy  Services and KeySpan
Home Energy Services.

     UK HoldCo - means  National  Grid plc or its successor as the highest level
holding  company in the National Grid group. US HoldCo - means National Grid USA
or its successor as the immediate  parent and holding  company for National Grid
plc's United States utility operations.  Immediate wholly-owned  subsidiaries of
National Grid USA will, upon completion of the Merger, include KeySpan,  Niagara
Mohawk Holdings,  Inc.,  National Grid USA Service  Company,  Inc., and National
Grid's New England utility affiliates.

     Where the term  "HoldCo" is used,  it refers to either or both of UK HoldCo
and US HoldCo.  Where explicit reference to one of the HoldCos is required,  the
term "UK HoldCo" or "US HoldCo" are used in full. Other  capitalized  terms have
the meaning assigned to them in the Joint Proposal.

2. Corporate Structure Following the Merger

     Following  the  Merger,   National  Grid  plc,  a  public  limited  company
incorporated  under the laws of England  and  Wales,  through  its  wholly-owned
subsidiary,  National  Grid USA,  will merge a merger  subsidiary  with and into
KeySpan Corporation, leaving KeySpan Corporation as the surviving corporation, a
wholly  owned  subsidiary  of  National  Grid  USA.  None of  KeySpan's  current


                                       2



subsidiaries will be affected by the Merger, and, following the Merger, all will
exist as the separate corporate entities they are today.  However, at some point
following the Merger, all corporate and administrative  services in the National
Grid USA  holding  company  system,  including  those now  provided  by  KeySpan
Corporate  Services  LLC and KeySpan  Utility  Services  LLC, may be provided by
ServiceCo,  defined below,  using the cost  allocation  methodology set forth in
section 4.2, below.

     Specifically,  National  Grid USA  intends  to combine  or  reorganize  the
existing  service company  subsidiaries  of National Grid and KeySpan.  National
Grid USA also intends to adopt the KeySpan  allocations for ServiceCo costs that
are not otherwise  charged  directly to affiliates.  The  combination of service
companies  and the  change in  allocation  method  will  occur  when they can be
implemented  most  effectively  following  the receipt of  necessary  regulatory
approvals and the completion of necessary system modifications.

3. Accounting Issues

     Under United States Generally Accepted Accounting  Principles (US GAAP) for
purchase  accounting,  the total  acquisition  price,  together with transaction
costs, in excess of the fair market value assigned to the assets and liabilities
of the  acquired  company are  recorded as  goodwill on the  acquired  company's
accounts.  National  Grid plans to "push  down" and  allocate  the excess  among
KeySpan Corporation and its subsidiaries. This approach is fully consistent with
US GAAP and with the  practice  adopted  in the  National  Grid  acquisition  of
Niagara Mohawk Holdings and its other US acquisitions.  Under FASB standards for
accounting for goodwill,  goodwill is not amortized against  earnings.  Instead,
goodwill is reviewed for  impairment  and written  down and  expensed  only in a
period in which the  goodwill's  recorded  value exceeds its fair value.  As set
forth in section 1 of  Appendix  5, no  goodwill  will be recorded on KEDNY's or
KEDLI's  regulatory  accounts  that  are  subject  to  the  jurisdiction  of the
Commission.  As a result,  there will be no ratemaking  effects  associated with
recording goodwill under GAAP US for KEDNY and KEDLI.


                                       3



     The  Commission's  approval  of the  KEDNY  and  KEDLI  Merger  Rate  Plans
signifies that such Rate Plans meet the accounting  requirements of Statement of
Financial Accounting Standards No. 71 and will do so throughout their terms.

     As of the Rate  Effective  Date,  KEDNY's and  KEDLI's  fiscal year will be
changed to a year ending March 31st. In any calendar year,  KEDNY and KEDLI will
limit the dividends  paid to US HoldCo in accordance  with section 2 of Appendix
5.

4. Rules Governing Affiliate Transactions

     4.1 Separation and Location:  HoldCo, KEDNY, KEDLI, and all affiliates will
each be operated as  separate  entities  and will  maintain  separate  books and
records of account. KEDNY, KEDLI, HoldCo, ServiceCo,  Regulated Affiliates,  and
National Grid Other  Affiliates  may occupy the same  building.  An  Unregulated
Competitive  Energy  Affiliate  may share a building  with KEDNY or KEDLI for no
longer than 180 days after its formation.

     4.2 Cost Allocation  Procedures:  Cost allocation procedures will assure an
appropriate allocation on a fully distributed basis to HoldCo, KEDNY, KEDLI, and
each Affiliate of the costs of any HoldCo or ServiceCo personnel,  property,  or
services used by them. HoldCo will implement  ServiceCo cost allocations for its
HoldCo  subsidiaries  that reflect the methodology  approved for use by KeySpan,
when this  conversion can be implemented  efficiently  and following  receipt of
required  regulatory  approvals.  Specifically,  rather than using operation and
maintenance (O&M) expenses as the basis for the general  allocation of ServiceCo
expenses,  the three-part allocator currently used by KeySpan Corporate Services
LLC,  based on revenues,  O&M expenses,  and assets,  will be used by ServiceCo.
This change,  which will only affect the pre-merger National Grid USA companies,
may require approval of the regulatory  commissions having jurisdiction over the
rates of the Regulated  Affiliates,  and is  conditioned  on the receipt of such
regulatory  approvals.  Following  consummation  of the  Merger,  the receipt of
required approvals,  and the implementation of necessary  accounting systems and
controls,  KeySpan's  allocation  methods will be adopted and KeySpan's  service
companies, KeySpan Corporate Services LLC and KeySpan Utility Services LLC, will
be phased out and consolidated with ServiceCo to the extent permissible and when
this conversion can be implemented efficiently.

     4.3 Revisions of Methodology and Audits:  Any future  revisions to the cost
allocation  methodology will be filed with the Commission's  Director of Finance
and Accounting and,  assuming  adequate  support is provided for such revisions,
will become effective after 60 days, unless an objection is raised.


                                       4



     Staff will have the right to audit ServiceCo,  including the examination of
authorized cost allocation  calculations  and review of internal audit policies,
procedures,  and reports, to receive assurance that applicable  transactions and
/or allocations are being carried out properly.

     4.4 ServiceCo Services:  Following the close of the Merger,  ServiceCo will
be authorized to perform Corporate and Administrative  Services to KEDNY, KEDLI,
Regulated  Affiliates,  Unregulated  Competitive  Energy Affiliates and National
Grid  Other   Affiliates.   In  the  course  of  providing  such  Corporate  and
Administrative   Services,   ServiceCo  employees  will  not  disclose  Customer
Information  or  System  Information  to  any  Unregulated   Competitive  Energy
Affiliate or act as a conduit for such Information,  excepting  disclosures that
are in compliance  with these rules,  Commission  orders,  rules or regulations.
While ServiceCo may perform call center operations for any US HoldCo subsidiary,
ServiceCo  will  establish  policies  and  procedures,  including  technological
safeguards,  to  ensure  that  Unregulated  Competitive  Energy  Affiliates  and
National Grid Other Affiliates do not have access to and do not receive Customer
Information or System Information.

     4.5 Provision of Services:  (a) In accordance  with section VI of the Joint
Proposal,  the service  companies of KeySpan and  National  Grid may continue to

                                       5



     Contracts  or  other  documentation  will  be  required  for  any  services
identified  in parts (d) and (e) that are expected to exceed $5 million over any
12 month period.

     4.6 June 2001  Niagara  Mohawk  Policy  Statement:  Affiliate  transactions
involving Niagara Mohawk are currently  governed by a document titled "June 2001
Policies and  Procedures  for Affiliate  Transactions."  National Grid will file
with the Director of  Accounting,  Finance and  Economics of the  Department  of
Public  Service  revised  policies,  procedures,  and  agreements  pertaining to
transactions among affiliates and for Niagara Mohawk,  KEDNY, and KEDLI prior to
the  consolidation of the service companies under section 4.4 above. That filing
will  be  included  as a  Merger  Reserved  Issue  in the  Joint  Proposal.  Any
disagreement  associated with the filing shall be referred to the Commission for
decision.

5. Rules Governing Human Resources

     5.1 Separation of Employees and Officers: KEDNY, KEDLI, and the Unregulated
Competitive  Energy  Affiliates will have separate  operating  employees,  which
restriction will not be deemed to preclude shared  Corporate and  Administrative
Services.  The  Secretary  and/or  Treasurer  of KEDNY or KEDLI may serve in the
equivalent  position for HoldCo or any affiliate,  but no other officer of KEDNY
or KEDLI may serve as an officer of an Unregulated Competitive Energy Affiliate.

     5.2 Employee Transfers: Employees may be transferred from KEDNY or KEDLI to
an Unregulated Competitive Energy Affiliate.  Such transferred employees will be
required  to resign  from KEDNY or KEDLI  unless  there is a  conflict  with the
collective  bargaining  agreement,  in  which  case  the  collective  bargaining
agreement would control. Transferred employees may not be reemployed by KEDNY or
KEDLI for a minimum of one year.  Employees  returning to KEDNY or KEDLI may not
be  transferred  back to the  Unregulated  Competitive  Energy  Affiliate  for a
minimum of one year. Similarly, employees may be transferred from an Unregulated
Competitive Energy Affiliate to KEDNY or KEDLI. Such transferred  employees will
be required to resign from the Unregulated  Competitive  Energy Affiliate unless
there is a conflict with the collective bargaining agreement,  in which case the
collective bargaining agreement would control.  Transferred employees may not be
reemployed by the Unregulated  Competitive Energy Affiliate for a minimum of one
year after transfer.  Employees returning to the Unregulated  Competitive Energy


                                       6



Affiliate  may not be  transferred  back to KEDNY or KEDLI for a minimum  of one
year.  Any  transferred  employee  will be prohibited  from sharing,  copying or
taking  any  Customer  Information  or System  Information  from KEDNY or KEDLI.
Otherwise,  employees may be  transferred  between KEDNY or KEDLI and HoldCo and
any of its subsidiaries without restriction.

     KEDNY's and KEDLI's  annual  reports to the  Commission  will show employee
transfers between them and Unregulated Competitive Energy Affiliates.

     5.3  Emergency  Access to  Employees:  The  foregoing  provisions  will not
restrict HoldCo or any of its subsidiaries  from making its employees  available
to KEDNY or KEDLI to  assist  in an  emergency  that  threatens  the  safety  or
reliability  of service to KEDNY or KEDLI  customers.  In such  event,  KEDNY or
KEDLI will pay the fully-loaded costs for the services of such employees.

     5.4  Compensation  for  Transfers  to  other  than  HoldCo  or a  Regulated
Affiliate:  An employee  transfer  credit equal to 25% of the employee's  annual
base salary will be applied to KEDNY's or KEDLI's  respective  Balancing Account
for all  transfers  from  KEDNY or KEDLI to an  Unregulated  Competitive  Energy
Affiliate.  The  requirement  to pay such  transfer  credit will be waived for a
period of four years immediately following the close of the Merger.

     5.5 Employee Compensation and Benefits: The compensation of KEDNY and KEDLI
employees and officers may not be tied to the financial and/or stock performance
of  any  Unregulated   Competitive  Energy  Affiliate  or  National  Grid  Other
Affiliate,  but may be tied to the  financial  performance  of Holdco  and stock
performance of UKHoldCo.

     Employees  of  HoldCo  and  all  or any  subset  of  its  subsidiaries  may
participate in common  pension and benefit  plans,  and the costs of such common
plans  will  be  equitably  allocated  in  accordance  with  the  approved  cost
allocation procedures.

6. Access to Books, Records and Reports

     Staff  will  have  full  access,  on  reasonable  notice,  and  subject  to
resolution of issues relative to confidentiality  and privilege (e.g.,  attorney
client,  attorney work product, self critical),  to: i) the books and records of
HoldCo and its majority-owned subsidiaries; and ii) the books and records of all
other HoldCo subsidiaries or affiliates,  in English, to the extent necessary to
audit and monitor any transactions that have occurred between KEDNY or KEDLI and
such  subsidiaries  or  affiliates.  Such  access to books and  records  will be
provided at KEDNY's or KEDLI's New York headquarters; provided, however, that if
such access is not  practicable,  access will be provided at another location in
KEDNY's or KEDLI's service territory at the Company's expense.


                                       7



7. Standards of Competitive Conduct

     7.1 Use of Corporate Name and Royalties: These Standards of Conduct will be
in lieu of any and all  royalty  payments  that could or might be asserted to be
payable  by HoldCo or any  HoldCo  subsidiary  or  imputed  to KEDNY or KEDLI or
credited to their  customers at any time. No provision  herein will be deemed to
restrict  any  HoldCo   subsidiary  from  using  the  same  name,  trade  names,
trademarks,  service  names,  service marks or a derivative of a name of HoldCo,
KEDNY or KEDLI,  or in identifying  itself as being  affiliated with the HoldCo,
KEDNY,  KEDLI or any other  affiliate.  Promotional  material  may  identify any
HoldCo subsidiary as being affiliated with KEDNY, KEDLI or HoldCo.

     7.2 Sales  Leads:  Except as set forth in this  Appendix 4, or as otherwise
approved  by the  Commission,  KEDNY  and KEDLI  will not  provide  sales  leads
involving customers in its service territory to any Unregulated Affiliate.

     7.3 Customer Inquiries:  KEDNY and KEDLI will respond to customer inquiries
as to  non-utility  services in  conformance  with the  following  Standards  of
Competitive Conduct:

     -If a customer  requests  information  from KEDNY or KEDLI  about  securing
commodity sales service from an ESCO,  KEDNY or KEDLI will provide a list of all
ESCOs authorized to do business in its service territory.

     -If a customer  requests  information  from KEDNY or KEDLI about oil-to-gas
heating system  conversions,  KEDNY or KEDLI will provide contact information of
licensed contractors pursuant to a program substantially the same as KEDNY's and
KEDLI's ValuePlus Program.

     -If a customer  requests  information  from KEDNY or KEDLI about  appliance
service contracts,  KEDNY or KEDLI will provide, on a rotational basis,  contact
information of licensed contractors offering service contracts in the customer's
vicinity.

     -If a customer  requests  information  from KEDNY or KEDLI about gas-to-gas
equipment  replacement,  KEDNY or KEDLI will  provide,  on a  rotational  basis,
contact  information  of licensed  contractors  performing  such services in the
customer's vicinity.


                                       8



     KEDNY and KEDLI may only provide  customers  information  about competitive
affiliates  operating  in the  business  areas  identified  above  as  part of a
response  to a  customer  inquiry  or  as  part  of  a  wider  dissemination  of
information  to  the  public  about  these  topics.  In  either  situation,  the
information  provided  about  any  HoldCo  subsidiary,   including   Unregulated
Affiliates, may not in any way be discriminatory to other competitors.

     All information made available  pursuant to the foregoing will also be made
available on KEDNY's and KEDLI's website.

     7.4 No  Advantage  Gained by Dealing with  Affiliate:  KEDNY and KEDLI will
refrain from giving any  appearance  that they speak on behalf of an Unregulated
Affiliate or that an Unregulated  Affiliate  speaks on behalf of them. KEDNY and
KEDLI  will not  engage  in any  joint  promotion  or joint  marketing  with its
Unregulated Competitive Energy Affiliates, provided, however, that this will not
prohibit the use of a common  corporate web site that  delineates  regulated and
unregulated entities and services.

     KEDNY and KEDLI will not represent to any customer, supplier or third party
that an advantage  may accrue to such  customer,  supplier or third party in the
use of their  services  as a result of that  customer,  supplier  or third party
transacting with any US HoldCo subsidiary.

     US HoldCo  subsidiaries  will not  represent to any  customer,  supplier or
third party that an  advantage  may accrue to such  customer,  supplier or third
party in the use of KEDNY's or KEDLI's  services  as a result of that  customer,
supplier or third party transacting with such subsidiary.

     7.5 No Rate  Discrimination:  All similarly situated customers will pay the
same rates for the same tariffed  services  provided by KEDNY or KEDLI. If there
is discretion in the application of any tariff  provision,  KEDNY and KEDLI will
not offer any affiliate  more favorable  terms and conditions  than it offers to
all similarly situated competitors of the affiliate.

     7.6 Complaint  Procedures:  Any competitor or customer of KEDNY or KEDLI or
any  affiliate  who believes  that KEDNY or KEDLI or an  affiliate  has violated
these  Standards of Conduct may file a written  complaint with KEDNY or KEDLI or
the subject  affiliate,  which will respond in writing within fourteen  business
days. Thereafter,  the complainant and KEDNY or KEDLI or the affiliate will meet
to resolve the  complaint  informally.  If no resolution  can be reached  within
thirty days  following  the  complainant's  receipt of KEDNY's or KEDLI's or the
affiliate's response, either party may request the assistance of Staff. If Staff
is unable to assist the parties in resolving the  complaint  within a reasonable
time, either party may seek resolution by the Commission.


                                       9



     If the  Commission  determines,  at any  time,  whether  as a result of the
procedure  outlined above or otherwise,  that KEDNY or KEDLI or an affiliate has
violated  these  Standards  of Conduct,  it will  provide  KEDNY or KEDLI or the
affiliate an  opportunity  to remedy such conduct or explain why such conduct is
not a violation. If KEDNY or KEDLI or the affiliate fails to remedy such conduct
within a reasonable  time after  receiving such notice,  the Commission may take
such remedial  action as is warranted  and for which it has authority  under the
Public Service Law.

8. Transfers and Leases of Property

     8.1 Personal  Property:  Transfers  of Personal  Property (or rights to use
such  property)  from  KEDNY  or  KEDLI  to an  Unregulated  Competitive  Energy
Affiliate or any National Grid Other  Affiliate  will be priced at the higher of
book value or fair market  value.  Any direct or  indirect  transfer of Personal
Property to KEDNY or KEDLI from an unregulated  affiliate  shall be at the lower
of book value or fair market value.

     Transfers  of  Personal  Property  (or  rights to use such  property)  from
KeySpan Corporate Services LLC or KeySpan Utility Services LLC to KEDNY,  KEDLI,
Regulated Affiliates,  ServiceCo,  or HoldCo to KEDNY or KEDLI will be priced at
book value.

     Transfers of Personal Property (or rights to use such property) between and
among KEDNY, KEDLI, Regulated Affiliates,  ServiceCo,  and HoldCo will be priced
at book value or cost.

     Gains associated with the transfer or lease of Personal Property in KEDNY's
or KEDLI's rate base will be credited to the  applicable  depreciation  reserve.
KEDNY or KEDLI  will have the  opportunity  to file a fully  supported  petition
seeking  recovery of any loss  associated with the transfer or lease of Personal
Property in KEDNY's or KEDLI's  rate base.  KEDNY and KEDLI will retain gains or
losses on the  transfer  or lease of  Personal  Property  not  included in their
respective rate base.

     Based on KEDNY's and KEDLI's  adherence to the foregoing  parameters and if
the  property  is not  needed  for  providing  regulated  utility  service,  the
Commission's  consent pursuant to PSL ss.ss. 69 or 70 is granted as being in the
public interest if the transfer or lease of Personal  Property is for $3 million


                                       10



or less. KEDNY or KEDLI will petition the Commission for its consent pursuant to
ss.ss.69 or 70 for the  transfer or lease of Personal  Property  that exceeds $3
million.  The provisions  governing  transfers of Personal Property to KEDNY and
KEDLI in this section do not assure the future rate recovery of these amounts.

     8.2 Real  Property:  If and when a facility is no longer  needed to provide
regulated gas services,  KEDNY or KEDLI will  evaluate  commercially  reasonable
disposition  alternatives for the facility,  including, but not limited to, sale
to an affiliate  or sale or lease to a third  party.  In the event it decides to
sell or  lease a  facility,  KEDNY or KEDLI  will  use  commercially  reasonable
efforts  to obtain  fair  market  value for the  facility  based on  independent
appraisals and market  conditions.  KEDNY and KEDLI may utilize brokers or other
service  providers  to identify  prospective  buyers or tenants,  or may utilize
other means designed to realize fair market value from the sale or lease.

     Gains  associated with the sale of real property in KEDNY's or KEDLI's rate
base will be credited to the applicable  Balancing Account.  KEDNY or KEDLI will
have the opportunity to file a fully supported  petition seeking recovery of any
loss  associated with the sale of real property in KEDNY's or KEDLI's rate base.
KEDNY and KEDLI will  retain  gains or losses on the sale of real  property  not
included in their respective rate base. Under no circumstances  will the sale or
lease of a facility  prevent  KEDNY or KEDLI from  providing gas services to its
customers,  or  from  otherwise  being  able to  discharge  its  public  service
responsibilities.  Moreover, any sale-leaseback transaction involving a KEDNY or
KEDLI facility will not increase  KEDNY's or KEDLI's annual cost of occupying or
utilizing the subject property.

     All  contract  documents  relative to the sale of  facilities  will include
provisions limiting, to the extent commercially practicable,  KEDNY's or KEDLI's
liabilities,   including  environmental  liabilities.   In  the  case  of  lease
transactions,  tenants will be required,  inter alia,  to maintain  commercially
reasonable  insurance  coverage to protect the leased  property,  and to observe
KEDNY's or KEDLI's requirements  regarding the use of the premises.  Any initial
lease term will not exceed five (5) years.

     Based on KEDNY's and KEDLI's adherence to the foregoing parameters,  to the
extent  that  efficient  management  of KEDNY's or  KEDLI's  property  portfolio
warrants  the sale or lease of a facility  subject to the  Commission's  consent
pursuant to PSL  ss.ss.69 or 70, that  consent is granted as being in the public
interest if the sale or lease or  sale/leaseback of facilities is for $3 million
or less. KEDNY or KEDLI will petition the Commission for its consent pursuant to
ss.ss.69 or 70 for  facility  sales,  leases,  or  sales/leasebacks  for over $3
million.


                                       11



9. Miscellaneous Provisions

     9.1 Annual Meeting:  Senior management of KEDNY,  KEDLI, and US HoldCo will
meet  annually  with  Senior  Staff to discuss  their  plans  related to capital
attraction and financial performance.

     9.2  Reporting  Requirements:   To  further  the  Commission's  ability  to
efficiently assess compliance with the terms of the Appendix 4, KEDNY, KEDLI and
HOLDCO shall file a report summarizing asset transfers, employee transfers, cost
allocations, affiliate transactions, and competitor/customer complaints prior to
each year's Annual Meeting.

     9.3 Adherence to Standards:  If the  Commission at any time makes a finding
that  compliance  with these Rules  Governing  Affiliate  Transactions  has been
lacking,  the  Commission  may  order an  independent  audit  of all  applicable
transactions, at KEDNY's or KEDLI's expense.

     9.4  Insurance:  KEDNY,  KEDLI and  HoldCo  subsidiaries  may be covered by
common  property/casualty  and other business insurance  policies.  The costs of
such policies will be equitably  allocated in accordance  with the approved cost
allocation procedures.

     9.5  Research  and   Development:   KEDNY  and  KEDLI  may  invest  in  the
commercialization  of research and development  products and  technologies  that
they have developed  consistent with these Standards of Competitive  Conduct. If
an  affiliate  elects to invest in the same,  it will  fairly  compensate  KEDNY
and/or KEDLI based,  among other things,  on the expected future benefits of the
investments,  assume the applicable  business risks, and will be entitled to the
benefits  associated  with  that  investment  to  the  extent  approved  by  the
Commission.

                       APPENDIX 5 - Financial Protections











Appendix 5: Financial Protections
- ---------------------------------

     Effective on the closing of the merger,  National  Grid will  implement the
following financial  protections for KEDNY and KEDLI. Such financial protections
will continue in effect unless and until such time as the Commission  authorizes
an express change.

1. Goodwill

     Although  goodwill may be recorded on KEDNY's and KEDLI's accounts pursuant
to United States Generally Accepted Accounting Principles (US GAAP), no goodwill
will be  pushed  down on the  regulatory  books  maintained  by  KEDNY  or KEDLI
pursuant to the Commission's  regulations following the Merger. Goodwill will be
excluded from rate base,  expenses and  capitalization  in the  determination of
KEDNY's  and  KEDLI's  rates and earned  returns  for New York State  regulatory
reporting purposes.

2. Dividend Payments

     KEDNY and KEDLI will register  with major  nationally  and  internationally
recognized bond rating  agencies,  such as Standard & Poor's,  Moody's  Investor
Service,  and Fitch Ratings, and intend to maintain at least an investment grade
credit  rating.  Provided  such  rating  is  maintained  with at least  two such
agencies,  subject to the other  provisions  of this Appendix 5, KEDNY and KEDLI
will be permitted to pay  dividends in any year up to an amount equal to the sum
of the following:  i) income  available for common  dividends  generated in that
year; ii) the  cumulative  amount of retained  earnings  accrued in prior years,
starting with the Effective Date of the merger; and iii) that portion of paid-in
capital  that was  recorded  on the books of KEDNY  and KEDLI as  unappropriated
retained earnings,  unappropriated undistributed earnings, and accumulated other
comprehensive  income immediately prior to the consummation of the Merger to the
extent such earnings were not already paid out as dividends in years  subsequent
to the closing of the Merger.

     To the extent that KEDNY and KEDLI desire to exclude  from the  calculation
of "income  available for common  dividends"  for the purposes of this provision
non-cash charges to income resulting from accounting changes,  charges to income
resulting  from  significant,  unanticipated  events or  impairment of goodwill,
KEDNY and KEDNY must first  notify the  Commission  of their intent to do so and


                                       1



provide an explanation  for such action.  KEDNY and KEDLI shall have the ability
to exclude the items  identified in the  notification if the Commission has not,
within  30  days  of the  notification,  indicated  that  additional  review  is
necessary.  Under no  circumstances  will the  balance of  retained  earnings go
negative as the result of dividend payments.

3. Dividend Restrictions

     KEDNY and/or KEDLI will be prohibited from paying common  dividends if: (a)
the senior unsecured bond rating of KEDNY or KEDLI (as appropriate) falls to the
lowest  investment  grade rating and there are negative  watch/review  downgrade
notices as determined by any two nationally  recognized rating agencies,  unless
the  Commission  approves such  dividends;  or (b) the senior  unsecured  credit
rating of National  Grid plc falls below  investment  grade as determined by two
nationally  recognized  credit rating agencies,  unless the Commission  approves
such dividends.  The prohibition from paying common dividends shall end when the
relevant  credit  rating is  restored,  or the negative  watch/review  downgrade
notices are removed and no negative  rating action is taken,  or the  Commission
approves the payment of such dividends.

4. Bond Ratings and the Cost of Debt

     If,  between the date of when the Merger closes and the  effective  date of
KEDNY's  or  KEDLI's  next rate  filing,  the bond  rating of KEDNY or KEDLI (as
appropriate)  falls below A- or A3 as  determined by two  nationally  recognized
credit rating  agencies,  then any long-term debt issued by the relevant company
during the period of such reduced credit rating will be priced as if it had been
issued by an A-/A3 utility at the same issue date, and any such  difference will
be  credited  to  KEDNY's  or  KEDLI's  (as  appropriate)  respective  Balancing
Accounts.  KEDNY's and KEDLI's  earnings  sharing  reports will then reflect the
actual debt rates outstanding for the Companies.

5. Debt Limit

     For any twelve-month period ending at the end of a quarter, KEDNY's Average
Total Debt will not exceed 56 percent of its Total Capital  excluding  goodwill,
and KEDLI's  average  Total Debt will not exceed 58 percent of its Average Total
Capital  excluding  goodwill.  For  purposes of this  section 5, "Total Debt" is
defined  as an amount  equal to (i)  long-term  debt,  plus (ii)  notes  payable


                                       2



(including  current  maturity  of  long-term  debt),  minus  the  average  daily
equivalents of cash and cash equivalents,  appearing on the consolidated balance
sheet of that  entity;  and "Total  Capital"  is defined as the sum of (i) Total
Debt, (ii) common shareholder equity (excluding  goodwill),  and (iii) preferred
stock appearing on the consolidated balance sheet of that entity.

     If the debt limitations for KEDNY or KEDLI (as appropriate) in this section
5 are exceeded,  KEDNY or KEDLI (as appropriate) will be afforded a fifteen (15)
month cure period to reduce the debt ratio to within the limits in this  section
5, during which period KEDNY or KEDLI,  as applicable,  will be prohibited  from
increasing the level of dividend  payments  (expressed as a percentage of common
equity  excluding  goodwill)  until the  average  debt ratio for a twelve  month
period  ending at the end of a  calendar  quarter  is within  the limits in this
section 5. Absent a Commission order to the contrary after a showing by KEDNY or
KEDLI (as  appropriate),  if the debt limit at the end of the cure period  still
exceeds  the limits in this  section 5, no further  dividends  will be paid from
KEDNY or KEDLI,  as applicable,  until the average debt ratio for a twelve month
period ending at the end of a calendar  quarter is reduced to the limits in this
section 5.

6. Merger Debt

     No debt  associated  with the Merger will be reflected as an  obligation of
either KEDNY or KEDLI.

7. Administration of Money Pools

     US HoldCo intends to create separate unregulated and regulated money pools,
subject to the receipt of necessary  regulatory  approvals  and when they can be
implemented  efficiently.  Participation  in the  regulated  money  pool will be
limited to KEDNY, KEDLI, Regulated Affiliates,  ServiceCo, and US HoldCo. KEDNY,
KEDLI,  Regulated  Affiliates,  and ServiceCo may  participate  in the Regulated
Money Pool as both borrowers and lenders.  US HoldCo may participate as a lender
only.
