      2002 KeySpan - Effective Strategic Execution
      Financial Community Presentation
      December 12 - New York
      December 16 - Boston

      Cover
      Slide 1 - Agenda - MT

      Slide 2  - Agenda - Strategy & Execution - RBC

      Thank You Mike and Good Morning

      It is our pleasure to present the KeySpan story.

      Despite all the turmoil in the energy sector, I am glad to report that
      KeySpan has not been directly impacted by these issues and...

      Slide 3  - KeySpan's has... - RBC

     ...KeySpan  has remained  focused on executing our strategy and  delivering
     value to our investors


      Slide 4  - KeySpan's Focused Strategy - RBC

      Our strategy remains consistent, viable and focused - "more of same" -
      with only some strategic refinements. We are committed to continuing to
      grow our core businesses in the Northeast and divesting our non-core
      businesses.

     o    KeySpan's Vision is to be the Premier Energy Company in the Northeast.

     o    Our strategy  continues to remain focused on our two core businesses -
          our gas distribution business and our electric generation business.

     o    In our gas distribution  business,  we are focused on the customer. We
          are  well   positioned   for  growth  by  operating  in  an  excellent
          marketplace  with strong customer  demographics,  a low penetration of
          natural gas and high gas usage  resulting from operating in the colder
          Northeast.  This  business  is  complemented  by our  Energy  Services
          business,  which  builds on our  regulated  footprint  and  delivers a
          portfolio of energy products and services to homes and businesses.

     o    We will enhance this growth by owning strategic gas pipelines, storage
          facilities and LNG assets in the Northeast

     o    Our  electric  generation  business  operates in the New York City and
          Long Island load  pockets.  We will continue to grow the earnings from
          this core business  through the  optimization of our existing 6,400 MW
          portfolio as well as through the  development  of new  generation  and
          asset acquisitions.

     o    To strengthen the focus on core  businesses,  we will continue to move
          to exit businesses that are not aligned with our strategy.

      Managing risk is an important component of our strategy...





      Slide 5  - Low Risk Profile- RBC

      ... And KeySpan's earnings have a low risk profile since 85% of our $1
      billion in EBIT comes from regulated, contractual and "load pocket"
      businesses.

     o    We have very predictable  revenues,  and stable earnings and cash flow
          streams.

     o    KeySpan  is in a  unique  position  in  that  we  essentially  sell  a
          portfolio of energy  products  and services to customers  with whom we
          already have a strong existing relationship.

     o    KeySpan does not have a large scale trading operation and,  therefore,
          is not subject to extreme volatility and liquidity problems.

      In addition, we have established a formal enterprise wide corporate risk
      management group to enhance our risk management.

     o    We formed an active senior executive Risk Management Committee and

     o    We hired a chief risk officer

     The success of our business is also enhanced by the positive  relationships
     we have with our constituents...






      Slide 6  - Working with our Constituents- RBC

     Over the years,  we have developed a strong working  relationship  with the
     regulators and the  communities  we serve.  It is this ability to work with
     our constituents that gives KeySpan a unique  opportunity to provide energy
     solutions in the Northeast resulting in enhanced value to our shareholders.

     Some examples include...

     o    We  recently  announced  the sale of our  Jamesport  property  on Long
          Island to New York State -- this preserves  existing historic farmland
          and  creates  a public  beach.  The New York  Times  wrote an  article
          earlier this month  commending  KeySpan for balancing the needs of the
          state, local communities and, of course, our shareholders

     o    Next, Our Ravenswood generation expansion project received approval in
          record time  because of KeySpan's  ability to work with the  community
          and  regulators  to create a solution  that reduced net air  emissions
          from the Ravenswood site by 25%.

      Management Team

     These relationships with our constituents are driven by a strong management
     team  consisting  of  experienced  leaders  with in depth  energy  industry
     knowledge.

      Corporate Governance

     Given the recent issues related to corporate governance,  let me assure you
     that KeySpan's  Corporate  Governance  program is based on "best practices"
     and already generally conforms to the new corporate governance guidelines.

     o    all of our Directors, other than myself, are non-employees, and

     o    all members of key board committees including the Audit,  Compensation
          & Nominating and Corporate  Responsibility  and Governance  committees
          are outside directors

      Let's now turn to our accomplishments in 2002

      Slide 7  - KeySpan's 2002 Report Card- RBC

     o    We achieved record gas growth additions

     o    Installed new generation under long term contracts

     o    Refined the Energy Services  business o Monetized some of our non-core
          assets.

o    And finally, from a financial perspective,

     o    we strengthened our balance sheet, and

     o    we are on target to achieve  our 2002  earnings  goal of $2.60 - $2.75
          per share and

     o    we maintained our $1.78 dividend, while reducing our payout ratio.

      Some of the specifics....first, gas growth




      Slide 8  - Gas Growth- RBC

     Despite the warmest winter on record, our gas business continued to grow at
     record  levels  converting  thousands of customers to gas - and we are near
     target to achieve our aggressive  goal of a record $65 million in new gross
     profit margin for 2002.

     o    Our fall  advertising  program is in full swing,  which highlights our
          free boiler program and the increased home value achieved by upgrading
          to natural gas

     o    Given the public's  sensitivity  to our nation's  reliance on imported
          oil, the outlook for the growth of natural gas demand  continues to be
          extremely favorable

      Next, our electric successes...


      Slide 9  - Electric Generation- RBC

      We installed 160MW of new peaking generation at Glenwood Landing and Port
      Jefferson, Long Island during the second quarter in time to meet the Long
      Island Power Authority's - LIPA's increasing summer demand requirements on
      Long Island - on budget and ahead of schedule

     o    We are very  proud that of the four  companies  building  new  peaking
          generation on Long Island for the summer, KeySpan was the first to put
          its new units into commercial production.

     In addition, we started construction on our new 250MW Ravenswood plant, the
     first new major  plant  under  construction  in the New York City market to
     help meet the increasing  load demands of the city.  This plant is expected
     to be on-line in late 2003.





      And moving on to the LIPA relationship...


      Slide 10  - LIPA Contracts- RBC

     We are pleased to have reached agreement with LIPA to extend the Generation
     Purchase  Right  Agreement  (GPRA) and the  Management  Services  Agreement
     (MSA).

      GPRA

     o    The original GPRA gave LIPA the option to purchase KeySpan's on island
          generation during a one year window ending May 27, 2002.

     o    The extended GPRA established a new option window commencing  November
          2004 and closing May 2005.

     o    As part of the  extension,  KeySpan will work with LIPA to address new
          energy supply options for LI such as repowering of our existing plants
          - which could provide KeySpan with new earnings opportunities.

      In addition,
      MSA

     o    The MSA contract, under which we manage and operate LIPA's T&D system,
          has been extended 31 months through December 31, 2008.

     These  extensions  provide  stability  for  our  shareholders  and  for the
     dedicated and highly skilled workforce,  who deliver the record performance
     of LIPA's T&D system and KeySpan's generating facilities.

     In terms of our relationship with LIPA, as you know, we recently  announced
     a problem with the reporting of estimated revenues recorded on their books.
     The error was made by KeySpan by over estimating their requirements. It has
     no financial  impact on KeySpan and had no impact on LIPA's customer bills.
     We have taken  responsibility and implemented measures to prevent this from
     happening  again.  KeySpan  has a  track  record  of  providing  LIPA  with
     outstanding  service  and  managing  the success of this unique and ongoing
     relationship,  and we are  confident  we can put this  issue  behind us and
     maintain a positive working relationship.

      And now the performance of our system






      Slide 11  - Operational Excellence- RBC

     We achieved  outstanding summer performance for both the KeySpan generation
     facilities and the operation of the LIPA T&D system.

      Generation

      During a summer where peaks were continually set and broken...

     o    Our Ravenswood plant had an availability of 97% and our largest unit -
          Ravenswood  Unit # 3 - "Big Allis" was  available  100% of the time to
          meet New York City's needs.

     o    And our Long Island  generation  responded to Long  Island's  needs by
          being available more than 98% of the time

      T&D

     o    Turning to the  operation of LIPA's T&D system,  KeySpan  continues to
          operate  the  system  at the  highest  performance  levels in New York
          State.

     o    Among overhead  utilities,  KeySpan ranks first in response time where
          we have an outage - we restored service to our customers in 71 minutes
          as compared to the average of an hour and forty-five minutes.


      Changing focus to our non-core assets


      Slide 12  - Monetization of Non-Core Assets- RBC

     We  continue  to be focused on our  commitment  to  monetize  our  non-core
     assets.

     In 2002, we closed on the sale of Midland  Enterprises - we received  gross
     proceeds of $240 million and retired approximately $135 million in debt.

     In  addition  to this  sale,  we  took  an  initial  step  towards  further
     monetizing our non-core assets by selling to Houston  Exploration  reserves
     from our joint venture with THX for $26.5 million.

     These sales are consistent  with our strategy and commitment to concentrate
     on our core  businesses.  The proceeds from these sales were used to reduce
     debt.

     At  this  point,   let  me  briefly   review  our  financial   performance,
     specifically our balance sheet improvements in 2002.





      Slide 13  - Strengthened Balance Sheet- RBC

     KeySpan's  strong  financial  profile and solid  balance  sheet support our
     focused strategy. Our solid balance sheet is the foundation for growth from
     our core operations.

     In 2002,  KeySpan took a number of steps to further  strengthen our balance
     sheet,  which  have  resulted  in an  improvement  to  our  debt  to  total
     capitalization ratio from 66% to 62%.

     We look to  further  improve  this  ratio  in 2003 and  further  strengthen
     KeySpan's financial profile as Gerry will discuss.

      Turning to earnings ...


      Slide 14  - Solid Earnings - RBC

     By  remaining  focused  on the  execution  of  our  strategy,  KeySpan  has
     continued to provide solid earnings growth for our shareholders,  driven by
     the growth in our core businesses.

     o    Since   KeySpan's  first  full  year  of  operation  after  the  LILCO
          transaction,  earnings have grown at an average compound annual growth
          of nearly 20%.

     o    Continued  execution of our strategy will enhance these  earnings into
          the future.

     o    At this time,  we are once again  reaffirming  our prior 2002 earnings
          guidance of $2.60 to $2.75 per share.





      Slide 15 -  Solid Core Earnings - RBC

     Switching  over to earnings  guidance  for 2003,  the  strength of our core
     businesses  will again drive our  earnings.  The  breakdown of our guidance
     consists of several components.

     o    Our Core  operations,  excluding  incremental  pension  and other post
          retirement  benefit expenses  (OPEBs),  are expected to increase 6% to
          $2.55 to $2.60 per share in 2003 - solid growth in our core business.

     o    Most companies are facing  increased  pension and OPEB costs resulting
          from the poor  performance  in the equity markets these past few years
          and we are no exception.

     o    Incremental  pension and OPEB  expenses are expected at $0.20 to $0.30
          per share.

     o    Our E&P business is also projected to grow -- by  approximately  $0.15
          per share to $0.35 to $0.45 per share

     o    Putting  it  all  together,  after  deducting  the  pension  and  OPEB
          expenses,  our earnings guidance for 2003 is $2.65 to $2.80 per share,
          a modest increase over 2002.

     In a nutshell, we continue to effectively execute our strategy.

     At this  time,  I would  like to  turn it over to  Wally  and Bob who  will
     discuss the drivers of our businesses


      Slide 16  - Agenda - WPP

      Slide 17 - KeySpan Gas Distribution - Size and Scale - WPP Thanks Bob, and
      Good Morning.

      Starting with the Gas Distribution business...

     ...  the  two key  drivers  of our  success  are our  size  and our  growth
          potential.

      In terms of size and scale:

     o    We are  currently  the  largest gas  company in the  Northeast  United
          States and among the 5 largest in the country.

     o    We now  serve  over 2.5  million  gas  customers  as a  result  of the
          integration of 6 gas utilities over the past four years.

      But more important than just size is our growth potential:

     o    We have more than 1 million remaining heating prospects in our region

     o    And we are quickly  converting  these prospects to gas as we expect to
          add nearly $65 million in new --- profit margins this year.

      When you drill down to each region we serve, you will see that we have a
balanced mix of opportunity.





      Slide 18  - Gas Distribution: "How We Make Money" - WPP

      New York

     o    In New York, our biggest utility, we have 1.2 million customers

     o    We have an allowed ROE of 13.25%,  with a sharing mechanism above this
          level, and have been earning near this level over the past few years.

      Long Island

     o    On Long Island,  which is our fastest growing market,  we have 500,000
          customers and are quickly adding to this total.

     o    and we have  steadily  improved our returns to get closer to the 11.1%
          ROE cap and have a similar sharing mechanism as NY.

      New England

     o    In  our  newest  territory,   we  have  more  than  800,000  customers
          throughout Massachusetts and New Hampshire.

     o    Here,  we  have  an  allowed  ROE  of  7-15%,   and  have  significant
          opportunities to improve returns

     o    Most of the improvement should come from growth

     Putting it all  together,  we expect the EBIT in our Gas  business  to grow
     from $515 million this year to about $580  million in 2003,  excluding  the
     pension  increase  - almost all of which  hits the gas  business.  The EBIT
     contribution  can be  broken  down  approximately  40% New  York,  with the
     remaining  contribution  split  almost  evenly  across  Long Island and New
     England.

     Excluding  the  pension  impact,  about half of the 2003 growth is expected
     from customer  additions and O&M  efficiencies,  with the remainder  coming
     from a return to normal weather relative to 2002's record warm weather.

      Let's step back a moment and look at our track record...





      Slide 19  - Track Record of Growth and Expansion - WPP

      Over the past four years, we have made great progress in adding new
      customers, while significantly expanding our infrastructure.

      On the Growth side:

     o    We have  continued to grow the mature New York business as new margins
          have  increased 20%,

     o    We have more than doubled the new margins  added since  acquiring  the
          Long Island business,

     o    And, we have already  increased the New England margins by 60% in just
          two year's  time,  and have the  opportunity  to mirror the success we
          have had on Long Island.

      So as you can see, the growth stems from all territories - balanced across
      each of the specific markets. The key here is the diversity of the growth
      by markets.


      Expansion

     During this time,  we have added 5 million  feet of new gas mains -- mostly
     on Long Island and in New England to support the increased  growth in these
     regions.  This  capital  investment  has  significantly  improved  the  gas
     infrastructure  and  created  many  new  sales  opportunities  by  bringing
     thousands of potential prospects closer to our gas system.

     Let's  now  look  at  how  we  have  been  able  to   capitalize  on  these
     opportunities...


      Slide 20 - Focus on New and Existing Customers - WPP Our Growth Strategy
      focuses on both new and existing customers.

      New customers

     o    In terms of new  customers,  the  `bread-and-butter'  of our growth is
          still  oil-to-gas   conversions  -  we  should  do  more  than  20,000
          conversions, again in 2002.

     o    We have  had  great  success  with  many of our  innovative  marketing
          programs  over the years  such as our `free  boiler'  program  in Long
          Island and New England.

     o    And we are now very  excited  about  our new  `MyQuotes.com'  program,
          which  allows  customers  to  complete  the  sales  process  over  the
          internet.  We added more than 400 customers through `MyQuotes' in 2002
          and hope to double this amount in 2003.

      New Products

     o    We are now  adding new burner  tips such as  natural  gas  fireplaces,
          Bar-B-Q's  and swimming  pool  heaters,  which can increase the annual
          margins by 50%. In fact, we added  approximately  1,500  swimming pool
          heaters this past year.

     o    And,  of  course,   we  are  still  very  excited  about   distributed
          generation.  On the  commercial  side,  we added  about $1  million in
          margins from new DG applications, including cooling and power systems,
          in 2002.

      Let's now look forward at our opportunity...





      Slide 21 - The Opportunity Going Forward... - WPP Overall, our territory
      is a little more than 50% saturated.

     1.   Our mature New York  market is nearly  80%  penetrated  as a result of
          decades of aggressive  marketing  programs.  Yet, there is still ample
          opportunity  to grow as all of the  remaining  prospects  are near the
          existing gas mains.

     2.   On Long Island,  we only have a 36% saturation  rate as most customers
          have historically heated with fuel oil.

     3.   And in New England,  the opportunity exists to double the current base
          as the region is only 50% saturated.

     Putting it all together, we have over 1 million remaining heating prospects
in our territory.


      Slide 22 - Where do the Prospects Reside? - WPP So where do the prospects
      reside?

      As you know, we categorize our prospects into 3 groups depending on their
      proximity to the gas system. Our 1 million prospects are divided evenly
      between the 3 groups:

     1.   `Cooking  Only'  prospects  are  low-use  customers  that  use gas for
          cooking  and can easily be  upgraded  to gas  heating at a low capital
          cost, if any, since they already have gas in their home or business.

     2.   `Near Gas Main'  prospects are those who currently do not use gas, but
          are `near' a gas main. These prospects are also financially attractive
          to KeySpan since they only require a moderate amount of capital.

     3.   The  `Managed  Expansion'  prospects  are  those  who are far from the
          existing  gas  mains,  for  instance,  towns  on the  East end of Long
          Island.  Here,  there are significant  capital costs for new mains and
          services so we need to manage our capital  investments  by  converting
          several prospects on each new main.

     Fortunately, 2/3's of the 1 million remaining heating prospects are `on' or
     `near'  the main,  which  enables  us to add a  balance  from each of the 3
     groups of prospects and achieve an aggregate IRR of 15% or better.

     So how do we optimize these prospects and even further improve the IRR's?





      Slide 23  - Sales Optimization Model - WPP

     o    We have  developed  a  sophisticated  Sales  Optimization  model which
          enables us to identify prospects in each territory and categorize them
          by metrics such as customer  demographics,  capital  requirements  and
          profit potential.

     o    The development of the  Optimization  Model is a natural  evolution of
          our prior innovative  marketing programs such as the `Free Boiler' and
          `Managed Expansion' programs. The Sales Optimization Model will enable
          us to better  capitalize on the opportunities we have created over the
          past several years by investing heavily in our infrastructure.

     o    For  instance,  we have analyzed all of our prospects and have started
          to target 27,000 prospects in 18 towns with the highest income levels,
          highest historic sales penetration rates and best market potential.

      This model will allow us to target neighborhoods with the most profitable
      growth opportunities and more efficiently utilize our capital.


      Slide 24  - Sales Optimization Model Enhances Capital Efficiency- WPP

     o    For 2003, we are reducing the growth  capital in our gas business from
          $200  million  to $150  million.  We will  also  keep our  maintenance
          capital  flat due to the  continued  use of new  innovations,  such as
          trenchless technology and mini-diggers.

     o    As a result,  although we plan to reduce capital  expenditures  by $50
          million, we are only modestly lowering our growth target by $4 million
          - maintaining an aggressive level of growth above $60 million.

     o    As you  can  see,  one of the  metrics  we use to  track  our  capital
          efficiency is the Capex-to-GPM  ratio. In 2002, we spent approximately
          $3  dollars  in growth  capital  for every  one  dollar of new  profit
          margin. For 2003, we are targeting a reduction to $2.50 in capital for
          every one dollar in growth.


     So that's the gas story. Size...Scale...Growth....  And improved Efficiency
     as we go forward.

     At this time I would  like to turn it over to Bob to discuss  our  Electric
     Services Segment...





      Slide 25  - Agenda


      Slide 26 - KeySpan Electric Services  - WPP

     As Bob mentioned earlier, the Electric Services segment is KeySpan's second
     core  business  of our  focused  strategy  -- one  of  our  key  businesses
     comprising $1.4 billion in gross revenue and a major driver of our earnings
     contributing over 25% to our EBIT.

     The electric  services  business,  currently  serving the New York City and
     Long Island areas, has two major components:

     o    We manage the Transmission & Distribution  system for 1.1 million LIPA
          customers on Long Island through a management services agreement.

     o    We own and operate about 6400MW of  generating  capacity - the largest
          investor owned generator in New York State. We provide essentially all
          of Long Island's power and approximately 25% of New York City's power.

     o    And our strategy for growing our  generation  business - is focused on
          the strategic Northeast region and

     o    consists of  maximizing  the value of our  existing  6400MW  portfolio
          .....  such as  repowering  these  plants and  maintaining  their high
          availability rates

     o    As  well  as  adding  new  plants...   through   either   acquisitions
          ...possibly  at  discounts  from  distressed   companies  ...  or  new
          construction.  We are currently looking to build new generation plants
          both on Long  Island  and New York City with  500MW  currently  in the
          construction or planning phase.

      Now turning to our electric EBIT forecast and its drivers...





      Slide 27 - Electric Services - How We Make Money- WPP

     The 2003 EBIT  contribution is projected to be in the range of $255 to $265
     million, a bit lower than the 2002 EBIT numbers.

      The 2003 projection can be broken down into two categories

     1.   The first  consists of the three  contracts we have in place with LIPA
          which  contribute  approximately  40% of the EBIT in this  segment - a
          solid and predictable earnings stream.

     2.   The second  category  contributes  the  remaining  60% of the EBIT and
          includes the Ravenswood plant in NYC and the new peakers  installed on
          LI in 2002.

     o    The new  peakers  are  under  a 25 year  contract  to  LIPA  and  will
          contribute a steady EBIT stream.

     o    The two major drivers of Ravenswood's EBIT are the capacity and energy
          markets.

      First turning to the capacity market

     o    NYC is a `Load  Pocket' - since there is limited  generation  capacity
          and there are significant transmission import constraints, there is an
          `In-City Reliability rule' that 80% of the peak capacity  requirements
          must be provided by in-city  generators - the KeySpan Ravenswood plant
          provides 25% of NYC's capacity requirement.

     o    In 2002, we received an average capacity payment of  $90/kilowatt-year
          --  lower  than  we  originally  projected  due  to a  change  in  the
          Independent   system  operator  --  ISO  methodology  for  calculating
          capacity, which artificially created excess capacity.

     o    For  2003,   we  are  assuming   capacity   payments   increasing   to
          approximately  $90-$95/  Kilowatt-year.  We are  forecasting  slightly
          higher  capacity  payments  in 2003  since the ISO has  corrected  its
          methodology for  calculating  capacity and includes the effect of load
          growth.



     Now turning to the energy, we continue to have significant opportunities in
     the high  priced  New York City  market.  o In the energy  market,  the key
     drivers are supply / demand balance,  transmission constraints, the weather
     and the economy.

     o    In 2002, we experienced an extremely hot summer which produced  record
          electric  demands on both Long Island and NYC, and received an average
          annual peak spark spread of about $25/MWH

     o    For 2003, we are assuming an average peak spark spread in the range of
          $20-$25/megawatthour,  down a bit from  this  year -- a  softening  in
          price due to the forecasted return to normal summer weather in 2003.

     Consistent  with  our  forecasting  style,  we  are  using  normal  weather
     assumptions  in  determining  our EBITs.  2003  earnings  projections  also
     reflect higher NYC property taxes and other costs and a full years earnings
     from the new peakers.


      Slide 28 - Our Focused Generation Portfolio- WPP

     Although some of the factors discussed,  such as excess supply, the economy
     and weather,  may impact  profitability  going  forward,  we believe we are
     better  insulated  than most of our  competitors  due to the relatively low
     risk  nature of our  generation  portfolio.  We have  developed  a low risk
     generation  portfolio with a mix of contractual and load pocket  generation
     and a conservative hedging strategy.

      As shown in the table:

     1.   2/3's of  KeySpan's  current  generating  portfolio is under long term
          contract to LIPA,  and  therefore,  not subject to the vagaries of the
          power market.

     2.   The other 1/3  represents  the  merchant  Ravenswood  plant,  which is
          located  in the  strategic  NYC load  pocket  with the bulk of its net
          revenues coming from capacity payments.

     3.   In addition,  you see that for the component that is least predictable
          - energy  payments - we plan to hedge 1/2 of the risk through  forward
          sales of peak electricity from Ravenswood.

     4.   In terms of our new  projects  going  forward to grow our business ...
          there will be continued  focus on risk  mitigation ... either entering
          into PPA's or assets located in load pockets.


     So, when you put it all  together,  you can see that KeySpan has a low risk
     generation portfolio, complemented by a prudent hedging strategy.

     Now I'd like to specifically  comment on the progress of the new generation
     projects.





      Slide 29 - New Low Risk Generation Projects- RJF

     We made significant progress in 2002 to build new power plants.

     As  Wally  discussed  earlier,  we are  currently  in the  construction  or
     planning phases for two new plants in NYC and LI.

      Ravenswood

     The first plant - a 250MW  combined  cycle  installation  at our Ravenswood
     site is on target and on budget for late 2003 operation.

     o    Located in NYC load pocket

     o    This facility  received Article X approval in record time in September
          2001 o It is the first new major plant under  construction  in the NYC
          market

     o    Cost of $350 million

     o    Construction is progressing according to schedule and

     o    Plant is approximately 40% complete

      Spagnoli Road, Long Island

     For the second  facility,  a similar 250MW combined cycle facility  planned
     for Melville,  Long Island,  its Article X was deemed complete in the first
     quarter of 2002, and Article X approval is expected in 1st quarter 2003.

     o    Expected operation in 2005

     o    Continue negotiations with LIPA regarding PPA.

     Again,  I want to reiterate  that these  plants fit into our  focused,  low
     risk, Northeast generation strategy

      Moving to our Energy Services segment...

      Slide 30 - Agenda





      Slide 31 - KeySpan Services - RJF

     Let me now take a few  minutes  to  discuss  our plans for our  unregulated
     businesses - starting with our core Energy Services segment.

     KeySpan  Services  is the  unregulated  business  segment of  KeySpan  that
     delivers a portfolio of energy-related products,  services and solutions to
     homes and businesses.  It builds upon our regulated  footprint and enhances
     the value of our customers.  Our challenge now - to turn our size and scale
     into  profitability  by  increasing  margins and  reducing  costs.  We have
     refined the business model and expect a positive earnings contribution from
     this  segment  in  2003.  In fact,  based on the  results  in  October  and
     November,  we expect to be  profitable  in the 4th quarter of this  current
     year.

      This business segment serves two specific markets:

     1)   the mass market, which is serviced by Home Energy Services, and

     2)   the large commercial market serviced by Business Solutions.

      Home Energy Services

     The  mass-market  offerings  include a mix of  annuity-type  contracts  and
     fee-based  services covering heating and central cooling system repairs and
     installations.

      Business Solutions

     o    In the large  commercial  market,  once again,  we have a portfolio of
          offerings that include a mix of annuity-based and fee-based services.

     o    We  provide  energy  solutions  that  include   designing,   building,
          operating, maintaining and fueling the energy needs of our customers -
          with   Mechanical   contracting   and  HVAC  work  being  the  biggest
          contributors.

     The 2003 EBIT  contribution from the services business segment is projected
     to be in the range of $10 -$20 million - a significant  improvement  from a
     2002 EBIT loss.

      KeySpan Services is a strategic fit for KeySpan ... Let me explain...
      Slide 32 - Role of KeySpan Services- RJF

     1)   KeySpan  Services  supports  our  vision  and  is  core  to  KeySpan's
          customer-focused strategy and strong Brand recognition

     2)   Customer  satisfaction  is enhanced by  providing  customers  with one
          company that they can go to for all of their energy needs. Home Energy
          Services  has  90%  customer  satisfaction  and 90%  service  contract
          renewal ratings.

     3)   And,  KeySpan  Services  builds  upon  the  value  of our 2.5  million
          regulated  customers.  As  gas  utility  customers  are  added  to our
          existing  customer  base,  we have the potential to double the overall
          value of a single customer by completing the initial gas  installation
          and providing an appliance service contract.

     This is a  critical  component  of our core  strategy  -  although  KeySpan
     Services  has not yet achieved its  financial  objectives,  it has played a
     strategic  role in  supporting  the  utility by  providing  high  levels of
     service and converting customers to gas.

     Going  forward,  we have refined our  operations and identified a number of
     growth drivers...





      Slide 33 - KeySpan Services - Growth Drivers - RJF

     As you may remember,  last year, we installed new  management in our Energy
     Services business - this new team has taken numerous steps in enhancing our
     financial controls and refining our operations.

      Home Energy Services

     o    In our Home Energy Services  segment,  we have shifted our strategy to
          lead with  services - which  provides a more  significant  margin - as
          opposed to leading with the low margin commodity.

     o    We  have  also  taken   significant  steps  toward  reducing  overhead
          associated with this business. For example:

     o    We  have  consolidated  our  unregulated  call  center  facilities  to
          effectively utilize our corporate resources in Melville,  Long Island,
          and

     o    We have exited the Westchester market.

     In terms of growth for Home Energy  Services,  the key is to build upon the
     services we currently offer:

     o    200,000 service contracts,

     o    25,000 annual on demand service calls, and

     o    Focusing more on installation services,  including the installation of
          gas boilers, and central air conditioning. The A/C business provides a
          nice balance to our winter-peaking business.


      Business Solutions

      Moving to Business Solutions:

     o    We have exited the higher risk general contracting business -

     o    In addition,  we have improved the financial  controls of the business
          and

     o    We have  integrated the operating  areas of the company into 3 hubs to
          better serve our 2,000 commercial customers.

     o    The growth  drivers  include a 2003 revenue  backlog of  approximately
          $250 million, and

     o    An  enhanced  focus on `niche'  industries  -- we are  focusing on the
          energy   projects   of   pharmaceutical   companies,   hospitals   and
          universities.

      In summary...

     The  operational  refinements  we  have  made,  combined  with  the  growth
     opportunities we have identified,  should help us achieve  profitability in
     2003,  and build a viable  business  that  complements  our  regulated  gas
     business.

      At this point, let me switch gears to energy investments...

      Slide 34 - Agenda





      Slide 35 - KeySpan Energy Investments- RJF

     This segment consists of our E&P, Gas Processing and Pipeline businesses.

     1.   We own 2/3's of The Houston Exploration  Company,  which has more than
          650 BCFe of proved reserves in the Gulf of Mexico and Texas.

     2.   In our Canadian gas processing  business,  we own 14 plants in Western
          Canada that process  approximately  1Bcf of natural gas per day.  This
          business has a total book value of  approximately  $400 million and is
          considered non-core and we plan to divest of it.

     3.   And in our gas pipeline/storage  business, which supports our core gas
          business,  we own 20% of the strategic Iroquois  Pipeline,  as well as
          50% of the proposed Islander East pipeline in a partnership with Duke.


     In terms of EBIT  contribution  in 2003,  our valuable E&P business  should
     provide EBIT in the range of $100 to $120 million - driven primarily by the
     favorable gas price environment...

      ... while our gas processing investment should earn about $25 million in
      EBIT and our Pipeline investment should earn about $10 million.


      Slide 36 - Houston Exploration Company- RJF

     1.   As you can see from this next slide,  our E&P business  will achieve a
          record production of 100 BCFe in 2002- double the level of 5 years ago
          for an average of 15% growth per year.

     2.   In terms of reserves -- most of which are natural gas -- we have grown
          by  about  the  same  15%  per  year.  3. We have  also  maintained  a
          consistent  hedging  program  and have hedged 65% of both our 2002 and
          2003 production.

     4.   When you put it all  together,  our E&P business has  continued to add
          value for our shareholders. In fact, over the past 5 years, the market
          cap of Houston Exploration has doubled to about $1 billion.

     So when you look at Houston Exploration from a `numbers  perspective',  you
     see a consistent track record of growth and value creation. As we have said
     many times,  we would be willing to sell Houston  Exploration  at the right
     price, but we continue to feel that we are creating more value by retaining
     this business in the near term.

     I will now turn it over to Gerry  Luterman  who will  review our  financial
     profile.

      Slide 37 - Agenda





      Slide 38 - 2002 Financial Initiatives - GL

     Thank You Bob and Good Morning...  My objective...  to summarize  KeySpan's
     financial position and ... Financial strategy --- both of which support the
     business and growth objectives that my colleagues have presented to you.

     Specifically,  I will address risk  management,  balance sheet,  cash flow,
     dividend, earnings, ... and conclude with our overall financial profile.

     In summary, 2002 was a very busy year in which we achieved virtually all of
     our financial objectives ... much of which further solidified our financial
     position

      To recap...

     1)   We took a number of pre-emptive  steps to strengthen our balance sheet
          and I will review these with you this morning

     2)   From an earnings  perspective  - we continued to achieve core earnings
          growth ... while  improving cash flow 3) We monetized  /some/ not all/
          of our non- core  assets ...  effectively  deploying  the  proceeds to
          reduce our debt levels

     4)   And from a risk  management  standpoint  ... we  established  a formal
          Enterprise- wide Risk Management process

      So, lets get started,

      Risk . . .Perhaps the signature word of 2002.

      The strength of KeySpan's financial profile is built upon our ability to
      manage the risks associated with each of our businesses...


      Slide 39 - Managing our Risks- GL

      Commodity Risk...

     From  a  commodity  standpoint,   we  have  a  number  of  risk  mitigation
     measures...which are built into the structure of each of our businesses.

      More Specifically...

     o    Gas: We have an automatic gas cost pass through in all utilities

     o    Electric:  The generation is located in the New York "load pocket" and
          / or has long term contracts associated with it

     o    E&P:  Unlike most companies in this space, we hedge about 2\3's of our
          production at "favorable" prices

      In terms of weather: "Love that Cold Weather"

      Gas Business:

     o    We have weather normalization in New York and Long Island, and

     o    In New England,  we purchased a weather derivative for 60% of the 2003
          winter volatility to protect

      against the impact of weather

      And on the regulatory front...





      Slide 40 - Managing our Risks --- Regulatory- GL

     Overall, we have benefited from strong relationships in all territories ...
     utilizing incentive rate making to benefit our shareholders and customers.

      More Specifically... Gas Business...

     o    Our  existing  gas rate  agreements  in New York and Long  Island have
          expired... with the terms of the prior agreements remaining in place

     o    In New England...

     o    the Essex , Colonial and Energy North agreements remain in place and

o        in Boston...the rate plan expired in 2002 ...

     o    for 2003,  the 2002  rates  remain in  effect.  We are  considering  a
          possible  rate filing in the first half of 2003.  which  would  impact
          only the last few months of that year.

     Obviously . . .by being able to  continue  with the  existing  terms of our
     rate agreements,  we demonstrate our continued  ability to carefully manage
     our ongoing costs.

      From an electric perspective...

     o    On Long Island,  we have the long-term LIPA contracts  which have been
          presented

     o    In New York, we work with the New York ISO and remain subject to their
          rules - which have been reasonably supportive given the nature of that
          marketplace.

      All in all, a reasonably good situation overall.

      Now, moving to the balance sheet...





      Slide 41 - Balance Sheet Strengthening - GL Our balance sheet continues to
      improve...

      During 2002, we took a number of steps to strengthen the balance sheet

     1)   Issued  $460  million  of `MEDS'  convertible  equity  units....  with
          between 80% - 100% of the these units considered equity in calculating
          the debt ratio for credit and bank covenants purposes . . .

     2)   Early renewal and successful  renegotiation of our $1.3 Billion credit
          facility,  which serves as a backup to our  commercial  paper program.
          This facility was over subscribed as 16 banks participated. If you are
          present... and I am sure you are... Thank You.

     3)   Effectively deployed the proceeds from the sale of our non-core assets
          -- Midland and the gas portion of the THX Joint  Venture - to pay down
          debt - as promised,  plus we took off $135  million of Midland's  debt
          from our balance sheet

     4)   Capitalized on the low interest rate environment by optimizing our mix
          of fixed and variable  debt. As of September 30, 2002, we had interest
          rate swap agreements in which approximately $1.3 billion of fixed rate
          debt had been "synthetically" modified to floating rate debt. In early
          November   2002,  we  terminated  two  of  these  interest  rate  swap
          agreements  ... and  received $81 million in  cash--including  accrued
          interest, which was also used... as promised... to pay down debt. This
          brought the overall benefit to over $100 million.

     5)   And we have decreased our debt to capital ratio to  approximately  62%
          from 66% at year-end 2001

      Turning Now to cash flow...


      Slide 42 - Cash Flow / Capital Expenditures- GL

     During 2003, we are  projecting to generate about $1 billion 'plus' in cash
     flow from  operations - an improvement of $100 million from 2002.  Remember
     the  pension  entry is  non-cash.  This cash flow will more than  cover our
     ongoing capital expenditures projected to be in the range of $850 million.

     o    Gas -- $250 million for maintenance

     o    Gas -- $150 million for growth... down $50 million from last year

     o    Electric - flat at $90 million

     o    Energy  Investments  and  Services -- at $50 million and $10 million -
          equal to last year

     o    And E&P - $300 million -- self-funded by the E&P internally  generated
          cash flows.

     o    At this  time...  the  only new  investments  on the  horizon  are the
          continued  investments in our new electric  generation  plants,  which
          have been on the  radar  screen  for a number of years - $300  million
          projected  in 2003  for the  completion  of the  250 MW  expansion  of
          Ravenswood and -- the continuation of the proposed new 250 MW plant on
          Long Island.

      Turning now to our dividend . . .





      Slide 43 - Solid Dividend- GL

      We are once again reaffirming our commitment to the $1.78 dividend - which
      currently yields in excess of 5%. It goes without saying . . .

     o    In this  volatile and  uncertain  market ... a secure and  sustainable
          dividend  is  an  important  part  of  KeySpan's   overall  return  to
          shareholders...  realizing  that  about half of our  shareholders  are
          retail and a good  portion  of our  institutional  holders  are either
          value or income fund oriented.

     o    Over the past few years, the payout ratio has  significantly  declined
          to about  the  current  65% ...  moving  towards  our  stated  goal of
          approximately 60%, which would trigger  "consideration" of raising our
          dividend.

      So much for dividends, now the tough one...

      Let me spend a few minutes addressing our Pension and OPEB situation...


      Slide 44 - Pensions \ OPEB's - GL

     Given the market's poor  performance over the last few years . . . Pensions
     and pension  accounting  have become one of the most  difficult and complex
     issues  impacting  business  today.  Let me now  bring  you up to  date  on
     KeySpan's situation. Starting with 2002 . . .

      2002

      In total, we have pension assets of about $1.9 billion...

     1)   Going  into  2002,  our  Pension  plans in the  aggregate  were  fully
          funded...whereas  OPEB's are not fully funded, which is the normal way
          of handling  this item.  We use a  combination  of cash and  insurance
          products to fund the OPEB liabilities

     2)   Our  assumptions in 2002 were  reasonable and more  conservative  than
          industry  average

          o    Discount Rate - 7% Industry Average - 7.5%

          o    Asset Return - 8.5% Industry Average - 9.25%

          o    Compensation increase - 4% - consistent with actual experience

     3)   We have true-ups for  approximately 50% of our Rate Agreements ... and
          are fortunate that the plans without the  regulatory  true-ups are the
          better funded ones

     4)   And lastly,  we have incurred an  incremental  $30 million of non-cash
          pension expense into our current 2002 guidance





Looking now at 2003...

     1)   We obviously have provided some  incremental  non-cash pension expense
          based on the market's continued poor performance... $0.20 to $0.30 per
          share

     2)   We do not  need and do not plan to make  any  changes  to our  current
          assumptions

     3)   We still have the 50% or so in regulatory true-ups

     4)   Using these factors,  we expect an incremental book expense of $50-$75
          million -- on top of the $30 million we built into 2002's guidance

     5)   However, there will be no required incremental cash funding,  although
          in 2003 we may choose to infuse some additional cash into the plans

      So, the `net-net' pension for 2003...

     $50 to $75 million in increased  non-cash book expense...  no required cash
     funding.

      Turning now to earnings... in the appendix of your package, we have given
      you the detailed assumptions and sensitivities to our internal
      forecast...We know you will tear into them and George Laskaris and his
      team stand ready to sit with you on them.

      Our 2003 earnings guidance...


      Slide 45 - 2003 Earnings Guidance - GL

    ... continues to be built upon the strength of our core business...

     >>   We expect 6%  growth in our core  operations...  in the $2.55 to $2.60
          per share range,  excluding incremental pension expense. I should note
          that we are  absorbing  all  other  O&M  expense  increases  - such as
          benefits increases, security costs, and insurance.

     >>   We are  projecting  our E & P earnings of $0.35 to $0.45 per  share...
          with 65% hedged at $3.40 to $4.55/Mcfe >> Wrapping it all together, we
          are  expecting  consolidated  earnings per share of $2.65 to $2.80 per
          share - an  increase  as  compared to last year - due to the growth in
          our core  and E&P  businesses  highlighted  in  today's  presentation,
          offset by the non-cash  `book' impact of incremental  pension and OPEB
          expense

     Also,  probably  equally  important...  From  a  cash  earnings  per  share
     perspective,  we are  projecting  $7.25-to-$7.50  per share, a 6%+ increase
     from the 2002 levels.

     Stepping   back...our  solid  financial   profile   underpins  our  focused
     strategy...





      Slide 46 - Financial Stability  - GL

     1.   A solid business model focused on our core  businesses,  which provide
          85% of our EBIT and a very predictable revenue stream...

     2.   A solid balance sheet ...

     3.   Prudent risk management and a continued low Beta

     4.   Strong  Earnings  with  stable  and  improving  cash  flows  given the
          regulated  nature  of  our  business  5.  And  lastly,  a  stable  and
          "committed  to"  dividend  that  provides an  attractive  yield with a
          declining payout ratio.

      Let me now turn it over to Bob for some closing comments...

      Slide 47 - Agenda

      Slide 48 - Differentiating KeySpan - RBC

      Thanks, Gerry.

     By this time in the presentation,  you should have a clear understanding of
     how KeySpan is differentiated form other companies within our industry. The
     energy  industry has been plagued by a number of  difficult  problems  this
     past year.

     When you look at the track record of KeySpan that we have presented  today,
     you can see that we score high in each of these areas:

     o    We have a focused strategy

     o    We have low-risk business profile

     o    We have a solid balance sheet

     o    Our  electric  business  is focused on  long-term  contracts  and Load
          Pocket locations

     o    And, we have always used `Best Practices' Governance policies.


      As we look to the future, our focus for 2003 is `more of the same'...





      Slide 49 - KeySpan's 2003 Scorecard- RBC

     1.   We will build upon our record gas growth and look to optimize  the mix
          of growth and capital expenditures

     2.   We will continue with our installations of new electric  generation by
          completing the Ravenswood expansion

     3.   We will enhance our operations  and customer  service by the continued
          use of new technologies

     4.   We will  continue to monetize  our non-core  businesses  as the market
          presents opportunities

     5.   We expect to achieve profitability in our Energy Services business

     6.   We will take steps to further strengthen our balance sheet

     7.   We will  achieve  our  earnings  target,  continuing  to grow our core
          businesses,  as well as our E&P business and will  accelerate the cost
          containment  programs  we  have  in  place  to help  offset  the  cost
          pressures we face.

     8.   And, of course, we will maintain our $1.78 dividend

      So, when you put it all together...


      Slide 50 - KeySpan --- A Compelling Investment - RBC

     We  believe  that  KeySpan  provides  you  with  a  compelling   investment
     opportunity.  As we have highlighted in today's presentation,  our strategy
     is very  focused  on our  core gas  distribution  and  electric  generation
     businesses.  These businesses have competitive  advantages  relative to our
     peer  energy  companies...  and  are  well-positioned  in  very  attractive
     markets.

     o    In the past, we have consistently  delivered value to our shareholders
          and outperformed our peers in every time period.

     o    In fact,  over the past decade,  while the Utility sector has provided
          only a 3% average return, KeySpan has delivered a solid return of 11%.

     We thank you for your support and  investment  over this time period and we
     expect to continue this track record in 2003 and beyond.

      Thank you. At this time, we would be happy to take your questions.



     Well,if there are no more  questions,  I would like to once again thank you
     for your investment and wish you a happy and healthy holiday season...  and
     a VERY COLD Winter. As a token of our  appreciation,  we have a new KeySpan
     truck for all of you.

      Thank you.
