ITEM 1.  BUSINESS

OVERVIEW

     KeySpan  Energy   ("KeySpan"  or  the   "Company")   provides  a  range  of
energy-related  services through operations and investments in selected areas of
the energy industry. The Company is the fourth largest gas utility in the United
States  with   approximately   1.6  million  customers  in  the  New  York  City
metropolitan  area. The Company  competes in five  principal  lines of business,
including  natural gas  distribution,  electric  services,  gas  exploration and
production, energy-related investments, and energy-related services.

           The  Company  was  formed  to   facilitate   the   combination   (the
"Combination"), completed on May 28, 1998, of KeySpan Energy Corporation ("KSE")
and its principal  subsidiary The Brooklyn Union Gas Company  ("Brooklyn Union")
and the non-nuclear electric generation and natural gas distribution  businesses
of the Long Island Lighting Company ("LILCO"). To effect the Combination, all of
the assets used by LILCO in connection with its gas distribution  business,  its
non-nuclear  electric  generation  business  and the assets  common to its prior
operations (the "Transferred  Assets") were transferred to the Company. The Long
Island Power  Authority  ("LIPA") then acquired all of the common stock of LILCO
for approximately $2.5 billion in cash and the direct or indirect  assumption of
certain  liabilities.  The Company  sold to the former  holders of LILCO  common
stock, shares of the Company's common stock and then acquired KSE by merger with
a wholly-owned subsidiary of the Company in exchange for shares of the Company's
common  stock.  Upon  completion  of these  transactions,  former  LILCO and KSE
shareholders  owned  approximately  68% and 32% of the  Company's  common stock,
respectively.

           The assets of LILCO not  transferred  to the Company  (the  "Retained
Assets")  were  retained  by LIPA and  primarily  consist  of  LILCO's  electric
transmission and distribution  system located on Long Island (the "T&D System"),
its 18%  ownership  interest in Nine Mile Point Nuclear  Power  Station,  Unit 2
("NMP2"),  located in upstate New York, and certain of LILCO's regulatory assets
and liabilities associated with its electric business.

           The Company was organized under New York law in 1998.  Brooklyn Union
was formed in 1895 through the consolidation of several existing companies,  the
oldest  of which  commenced  operations  in  1849,  providing  gas  distribution
services  throughout  the New York City boroughs of Brooklyn,  Staten Island and
most of Queens,  New York.  LILCO was organized in 1910 to provide  electric and
gas services in the Long Island  counties of Nassau and Suffolk and the Rockaway
peninsula in the borough of Queens, all in New York.

           As used  herein,  the  "Company" or  "KeySpan"  refers to  MarketSpan
Corporation d/b/a KeySpan Energy ("KeySpan Energy"),  Brooklyn Union and KeySpan
Gas East  Corporation  d/b/a Brooklyn Union of Long Island  ("Brooklyn  Union of
Long Island"),  its two principal gas distribution  subsidiaries,  and its other
subsidiaries,  individually  and in the aggregate.  In 1998, the Company changed
its  fiscal  year end from March 31 to  December  31.  For  financial  reporting
purposes,  financial statements included,  or incorporated by reference,  herein
for the period  ending  December 31, 1998 are for the nine months then ended and
have been prepared on the basis that LILCO is deemed to be the acquiring company
in the Combination for financial reporting purposes. Unless otherwise specified,
other  information  contained  in Part I hereof has been  compiled on a combined

INDUSTRY AND COMPETITION

           The electric and natural gas sectors of the regulated energy industry
are  undergoing   significant   changes,  as  market  forces  are  replacing  or
supplementing  rate regulation as a means of controlling  prices for natural gas
and  electricity.  The exposure of utilities to competition  places pressures on
them to maintain  market  share and  profits  and manage the costs of  providing
services as their  customers  gain access to lower cost  supplies of natural gas
and electricity.  Competition also presents utilities with greater opportunities
to  manage  the  cost of  their  natural  gas  and  electric  supplies,  to earn
unregulated profits on energy sales and to expand their business activities.

 
                                       2

           Historically,  government regulation served both to control prices in
the natural gas and electric sectors of the energy industry and to substantially
shield  industry  participants  from  competition.  The  natural  gas sector was
segmented into three regulated parts: production; interstate transportation; and
franchised  retail sales and local  distribution.  The electric  sector featured
vertically   integrated   utilities  providing   generation,   transmission  and
distribution   services  for  their  franchised   service   territories.   Under
traditional rate  regulation,  utilities were provided the opportunity to earn a
fair, but regulated,  return on invested capital in exchange for a commitment to
serve all  customers  within a franchised  service  territory.  An extensive and
complex regime for the regulation of public utility companies and public utility
holding companies limited natural gas and electric utilities'  opportunities for
geographic expansion and business diversification.

           Between  the 1930's and the late  1970's,  federal  and state  energy
regulatory  policies  remained  relatively  stable,  and  the  structure  of the
regulated  energy industry changed little.  However,  after the energy crises in
the  1970's,  new  legislation  and changes in  regulatory  policy set in motion
competitive  forces  that  are  reshaping  the  energy  industry,   dramatically
increasing business opportunities for natural gas and electric companies.

           Beginning in 1978 with federal legislation that authorized the phased
deregulation of wellhead natural gas prices and the establishment of unregulated
electric generation companies, competition has been increasingly introduced into
segments  of the  regulated  energy  industry.  To foster  competition,  federal
regulators  adopted "open access" rules which  required  interstate  natural gas
pipelines and electric  transmission  systems to "unbundle" retail sales,  I.E.,
the sale of gas or electricity,  from transportation and transmission  services.
Open access also required interstate gas pipelines and electric  utilities,  for
the  first  time,  to  provide  transportation  and  transmission  service  on a
non-discriminatory  basis to all qualified  customers.  Recent initiatives would
also permit market forces,  rather than  regulation,  to establish rates charged
under  short-term  contracts for interstate  natural gas  transportation  and to
determine  the  allocation  of  increased  electricity  costs that  result  when
electric transmission constraints prevent lower priced electricity from reaching
electric customers. By enabling natural gas producers and electric generators to
reach new  markets,  open access  policies  led to  intensified  competition  in
wholesale  markets and began to alter the geographic  character of the industry.
No longer  typified by isolated  local  companies,  the natural gas and electric
sectors in many parts of the  country  today  include a growing  number of firms
with regional, national and international dimensions.

           Parallel changes in the regulation of retail electric and gas markets
are being  implemented by many state public utility  commissions,  including the
Public  Service   Commission  of  the  State  of  New  York   ("NYPSC").   On  a
state-by-state basis,  initially in the Northeast,  Mid-Atlantic and California,
and now  spreading  to other  regions,  local  franchised  utilities  are  being
required  to separate  their  marketing  and retail  sales  businesses  from the
physical  distribution of natural gas and  electricity  through pipes and wires.
Just as at the federal level, distribution services are increasingly required to
be unbundled from retail sales, and made available on a non-discriminatory  open
access  basis  to  all  qualified  retail  customers.  Retail  natural  gas  and
electricity  marketers  are being  permitted to compete for energy  customers in
what were formerly  exclusive  service  territories  of electric and natural gas
utilities.  However,  natural gas and  electric  utilities  are likely to remain
exclusive providers of unbundled  distribution services through pipes and wires,
and may remain  obligated  to continue to sell  natural  gas or  electricity  to
customers who do not select other suppliers.

                                       3

           In New York State,  large-volume  retail  customers have been able to
purchase natural gas supplies  directly from  non-utility  vendors for more than
ten years,  while  direct sales to  aggregations  of small  customers  have been
permitted  since 1996. New York  regulators  are  commencing new  initiatives to
further enhance retail competition in the state.  Similarly,  the NYPSC has been
encouraging the development of retail  competition in the electric sector in New
York. In the past two years,  electric utilities have begun to unbundle electric
sales from retail distribution  services,  open their franchised  territories to
competitors,  transfer control over their transmission systems to an independent
system operator, and divest many of their generating plants.

           The  introduction  of competition  for retail  electricity  sales may
threaten the ability of electric  utilities to recover their past investments in
electric generating plants (and, in some cases, related transmission facilities)
to the extent  that the cost of  producing  electricity  from  those  generating
plants exceeds the competitive  market price for  electricity.  In consideration
for opening franchise service territories to retail  competition,  many electric
utilities are being permitted to recover potentially  "stranded"  investments in
electric generation and associated transmission through charges to all customers
receiving  distribution  and  transmission  services.  In many cases, the market
value of electric  generating  plants and the amount of stranded  investment  is
being  determined  through  the  divestiture  of electric  generating  plants in
well-publicized auctions. The sale of generating plants and recovery of stranded
costs (to the extent  they  remain  after  divestiture)  is  providing  electric
utilities with  substantial  cash infusions which, in some cases, are being used
to repurchase stock or to finance  acquisition of other energy assets,  often in
different  regions  of  the  country  or  internationally.  Many  utilities  are
attempting  to  diversify  their lines of  business,  while some are choosing to
concentrate  on one or two  industry  segments,  such as natural gas or electric
distribution or electric generation.  Several New York investor-owned  utilities
have commenced the sale of their non-nuclear  generating  plants.  The Company's
pending purchase of the Ravenswood generating plant, as discussed below, results
from a plan under which  Consolidated  Edison  Company of New York,  Inc.  ("Con
Edison")  is  divesting  a  substantial  portion of its  non-nuclear  generating
capacity. See "The Company - Electric Services."

           A  significant  number of natural  gas and  electric  utilities  have
reacted to the changing  structure of the regulated  energy industry by entering
into business combinations, with the goal of reducing common costs, gaining size
to better withstand  competitive  pressures and business  cycles,  and attaining
synergies  from the  combination  of electric  and natural gas  operations.  The
Combination  and related  transactions  which  resulted in the  formation of the
Company shares many of these attributes.

           The  transformation  of the energy  industry  is an ongoing  process.
Larger regional,  national and international  companies are being formed through
acquisitions and mergers. The remaining legal barriers to interregional  natural
gas and electric distribution  companies,  which have been relaxed as the result
of regulatory  decisions,  are the subject of legislative  proposals calling for
repeal or substantial  modifications.  The advent of industry  restructuring has
meant that  regional,  national and  international  companies  are  increasingly
offering  energy  consumers  a wide  array of choices  as to the  supply,  type,
quality and cost of natural gas and electric services. For the Company, industry
restructuring  means increased  opportunities to enter new markets and pressures
to manage its costs of doing business.

BUSINESS STRATEGY

           The Company seeks to become a premier energy company with  operations
focused  in the  Northeastern  United  States,  the Gulf of Mexico  and  Western
Canadian supply basins as well as selected international areas where the Company
identifies opportunities for growth in those energy-related lines of business in
which the Company has developed  recognized  expertise.  The Company  intends to
grow through acquisitions and selected energy-related  investments; by expanding
its gas  distribution  business,  particularly  on Long Island;  by  emphasizing
superior  customer  service;  and by taking  advantage of the  increasing  trend
towards  deregulation  and competition to offer an expanded array of services to
its customers.

           Key elements of the Company's business strategy include:

               ENERGY-RELATED INVESTMENTS. In recent years, the Company has made
        a number of  acquisitions  and  energy-related  investments  designed to
        enhance its presence in the Northeastern  United States. The Combination
        transformed  the  Company  into the  leading  natural gas company in the
        Northeast,   with   approximately  1.6  million  gas  customers  in  two
        contiguous gas distribution  service  territories.  The Combination also
        gave the Company one of the largest power generation capabilities in the
        region, with over 4,000 megawatts of generation capacity.  Subsequent to
        December 31,  1998,  the Company  entered  into a definitive  agreement,
        subject to regulatory  approvals,  to acquire a 2,168 megawatt  electric
        generating  facility in New York City from Con Edison. Upon consummation
        of that  transaction,  the  Company's  power  generation  capacity  will
        approximate 6,200 megawatts. Consistent with the Company's long-standing
        investment in the Iroquois pipeline, the Company recently acquired a 25%
        interest in the proposed  Cross Bay pipeline,  which will  transport gas
        from interstate  pipelines in New Jersey to New York and Long Island. In
        addition,  the  Company has  expanded  the  business of its  unregulated
        energy services operations, through the acquisition of Philip Fritze and
        Sons,  one of the  largest  heating,  ventilation  and air  conditioning
        contractors in New Jersey.

               The Company has also made significant investments beyond its core
        market area. In 1998, for example,  the Company  acquired a 50% interest
        in  certain  midstream  natural  gas  assets  of Gulf  Canada  Resources
        Limited,  creating a partnership known as Gulf Midstream  Services.  The
        Company also purchased an additional  25.5% interest in Premier  Transco
        Ltd. (resulting in an aggregate 50% interest),  which transports natural
        gas  through an 84-mile  pipeline  from  southwest  Scotland to Northern
        Ireland.

               These   acquisitions   and  investments   reflect  the  Company's
        commitment  to  enhancing  its  presence  as an energy  company  focused
        primarily  on  the   Northeastern   United   States,   with   additional
        complementary  interests  in the Gulf of  Mexico  and  Western  Canadian
        supply basins, as well as Northern Ireland. The Company anticipates that
        it will continue to target other  acquisitions and investments that also
        provide it with  opportunities  to increase its  penetration of selected
        energy markets in those core geographic areas.

               EXPANDED GAS  DISTRIBUTION  SERVICES.  The Company has achieved a
        high degree of penetration in its Brooklyn Union service territory, with
        approximately  79% of  all  one-and  two-family  homes  currently  using
        natural  gas  for  space  heating.  In  contrast,  only  30% of  one-and
        two-family homes in the Brooklyn Union of Long Island service  territory
        currently use natural gas for space heating.  The Company believes there
        is significant  opportunity for increased penetration of the Long Island
        service territory and intends to make capital expenditures to expand its
        gas distribution infrastructure in order to support long-term growth. In
        addition, the Company expects to focus marketing efforts throughout both
        service territories.  Examples of such marketing efforts include efforts
        to  convert   customers   from  oil  to  gas  heat  and  to  target  new
        construction,  small to medium  commercial  businesses  and large volume
        dual-fuel customers.

               SUPERIOR CUSTOMER SERVICE.  The Company's utility operations have
        an  outstanding  reputation  for  customer  service  and  have  received
        consistently  excellent marks for customer loyalty and satisfaction,  as
        measured by independent customer-satisfaction  specialists. In 1998, the
        Company was the recipient of the Emergency  Response Award of the Edison
        Electric  Institute,  which honored the Company for  restoring  electric
        power  for  LIPA  after  a  severe  thunderstorm  on  Long  Island  last
        September.  Similarly,  Brooklyn  Union was  awarded the 1998 Brand Keys
        Customer Loyalty Award as the U.S. energy provider that had achieved the
        highest  level  of  success  in  anticipating  and  exceeding   customer
        expectations.  The Company  intends to continue  to  emphasize  superior
        customer  service,  both to  differentiate  itself from  competitors  as
        markets  become  increasingly  deregulated  and  to  take  advantage  of
        cross-selling  opportunities  available in complementary  energy-related
        services  such as appliance  repair and energy system  installation  and
        management.

               EXPANDED  SERVICES.  With  its  strong  market  presence  in  the
        metropolitan   New  York  City  area,   the   Company   believes  it  is
        well-positioned   to  provide  customers  with  an  expanding  array  of
        energy-related services. In recent years, the Company has begun to offer
        gas and electric  marketing services  throughout New York,  Connecticut,
        New Jersey,  Maryland,  Pennsylvania  and Ohio and appliance  repair and
        related  services  and  energy  management   services  for  residential,
        commercial and industrial customers throughout the metropolitan New York
        City  area.  The  Company   believes  that  continuing   trends  towards
        deregulation and competition,  coupled with growth in its customer base,
        will afford it  opportunities  to expand those  services both within and
        outside its  traditional  service  territories.  The Company also owns a
        250-mile  fiber optic  telecommunications  network on Long Island and is
        currently  exploring  various business  opportunities to take commercial
        advantage of that network.

THE COMPANY

                                GAS DISTRIBUTION

OVERVIEW

           The Company  sells,  distributes  and  transports  natural gas in two
separate, but contiguous service territories of approximately 1,417 square miles
in the aggregate in the New York City  metropolitan  area.  The Company owns and


                                      6
<PAGE>

operates  gas  distribution,  transmission  and storage  systems that consist of
approximately 10,036 miles of distribution pipelines,  578 miles of transmission
pipelines and two gas storage facilities.  The Company serves  approximately 1.6
million customers,  of which approximately 1.5 million, or 94%, are residential.
Gas is offered  for sale to  residential  customers  on a "firm"  basis,  and to
commercial and industrial customers on a "firm" or "interruptible" basis. "Firm"
service is offered to customers under schedules or contracts which anticipate no
interruptions,  whereas  "interruptible"  service is offered to customers  under
schedules or contracts which anticipate and permit interruption on short notice,
generally in peak-load  seasons.  Gas is available at any time of the year on an
interruptible  basis,  if the  supply is  sufficient  and the  supply  system is
adequate.  The Company also participates in the interstate  markets by releasing
pipeline capacity or bundling pipeline capacity with gas for "off-system" sales.
An  "off-system"  customer  consumes  gas  at  facilities  located  outside  the
Company's service territories,  by connecting to the Company's facilities or one
of its transporter's facilities, at a point of delivery agreed to by the Company
and the  customer.  The  Company  purchases  its  natural  gas  for  sale to its
customers under long-term supply  contracts and short-term spot contracts.  Such
gas is transported under both firm and interruptible  transportation  contracts.
In  addition,  the  Company has  commitments  for the  provision  of gas storage
capability and peaking supplies.

           During 1998, on a Combined  Company  Basis,  gas revenues were $1.760
billion, or 54% of the Company's  revenues,  and gas operating income was $218.8
million, excluding special charges related to the Combination.

           The gas  operations of the Company can be  significantly  affected by
seasonal weather  conditions.  Traditionally,  annual revenues are substantially
realized  during the  heating  season as a result of higher  sales of gas due to
cold weather. Accordingly,  operating results historically are most favorable in
the first and fourth  calendar  quarters.  However,  the  Company's  gas utility
tariffs contain weather normalization adjustments that provide for recovery from
or refund to firm  customers  of  material  shortfalls  or  excesses of firm net
revenues  (revenues less  applicable gas costs,  if any) during a heating season
due to variations from normal weather. See "Regulation and Rate Matters."

SALES AND DISTRIBUTION

           The  Company is the fourth  largest gas  distribution  company in the
United States, providing, through its gas distribution subsidiaries, natural gas
sales and transportation  services to customers in the New York City boroughs of
Brooklyn,  Queens and Staten  Island and the Long Island  counties of Nassau and
Suffolk.

*Excludes special charges and tax benefits associated with the Combination.

           The Company sells gas to its firm gas customers at the Company's cost
for such gas,  plus a charge  designed  to  recover  the  costs of  distribution
(including  a return of and a return on invested  capital).  The Company  shares
with its firm gas  customers net revenues  (operating  revenues less the cost of
gas purchased for resale) from off-system sales and, in addition, Brooklyn Union
of  Long  Island   credits  its  firm  gas   customers  all  net  revenues  from
interruptible gas sales, thereby reducing its rates to these firm customers.

           All of the Company's  retail gas customers became eligible in 1996 to
purchase  gas  directly  from  suppliers  other than the  Company's  gas utility
subsidiaries. At December 31, 1998, approximately 32,900 residential, commercial
and industrial customers, with annual requirements of approximately 19,500 MDTH,
or 10% of the Company's annual firm gas system requirements, purchased their gas
supply from sources  other than the Company.  If a customer  decides to purchase
gas from another supplier, the supplier obtains the gas and transports it to the
Company's  distribution  system.  The  Company  then  delivers  the  gas  to the
customer's  premises  through the  Company's  system of  distribution  mains and
service lines. In addition to delivering gas that customers  purchase from other
suppliers,  the Company has been providing metering,  billing and other services

                                       8

<PAGE>

for aggregate rates that are comparable to the distribution  charge reflected in
otherwise applicable sales rates to supply comparable customers.

           On a Combined Company Basis, actual firm gas sales and transportation
quantities from gas  distribution  operations in 1998 were 179,304 MDTH compared
to 203,587 MDTH in 1997 and 202,377 MDTH in 1996.  (An MDTH is 10,000 therms and
reflects the heating content of  approximately  one million cubic feet of gas. A
therm  reflects  the heating  content of  approximately  100 cubic feet of gas.)
These major  variations in quantities are primarily due to weather.  Measured in
annual degree days, weather was 17.5% warmer than normal in 1998, normal in 1997
and 4.8% colder than normal in 1996. After normalizing for weather, firm volumes
in 1998 were approximately the same as 1997.

           On  a  Combined  Company  Basis,  on-system   interruptible  volumes,
off-system  sales  (sales made to  customers  outside of the  Company's  service
territories)  and related  transportation  in 1998 were 65,482 MDTH  compared to
73,132  MDTH in 1997  and  59,139  MDTH in  1996.  The  decrease  in  total  gas
throughput  during 1998 reflects the effects of warmer weather and the fact that
Brooklyn Union discontinued its off-system sales program beginning April 1, 1998
and  replaced  it with a  management  agreement  with  Enron  Capital  and Trade
Resources Corp. and its parent company, Enron Corp. (collectively,  "Enron"), in
which Enron pays the Company a fixed fee in exchange for the right granted Enron
to earn  revenues  based upon its  management  of  Brooklyn  Union's  gas supply
requirements, storage arrangements, and off-system capacity.

           During 1998,  the Company  continued to grow in its existing  service
territories and to expand into new markets. In the Company's service area of the
New York City boroughs of Brooklyn, Queens and Staten Island,  approximately 79%
of one- and  two-  family  homes  currently  use gas for  space  heating,  while
approximately  48% of the multi-family  market and 63% of the commercial  market
use gas for space heating.  In these areas,  the Company  intends to seek growth
with an  aggressive  marketing  effort  designed  to  encourage  conversions  of
residential and  multi-family  homes and businesses from fuel oil to natural gas
heating. In the Company's service area of the Long Island counties of Nassau and
Suffolk and the Rockaway  peninsula of Queens County,  approximately 30% of one-
and  two-family  homes  currently  use  natural  gas for  space  heating,  while
approximately  17% of the multi-family  market and 57% of the commercial  market
use gas for space heating.  In these service areas, the Company will seek growth
through  the  expansion  of its  distribution  system  as  well as  through  the
conversion  of  residential  homes  and the  pursuit  of  opportunities  to grow
multi-family, industrial and commercial markets. The Company also offers special
area  development  and  incentive  gas  rates to  multi-family,  commercial  and
industrial  businesses that move to or expand  operations in designated areas of
the Company's service territories.

SUPPLY AND STORAGE

           The  Company  has  contracts  for  the  purchase  of  firm  long-term
transportation  and storage  services.  The Company's gas supplies are purchased
under  long-term  contracts  and on the  spot  market  and  are  transported  by
interstate  pipelines  from domestic and Canadian  sources.  Storage and peaking
supplies are available to meet system requirements during winter periods.

           Regulatory  actions,  economic  factors and changes in customers  and
their preferences  continue to reshape the Company's gas operations  markets.  A
number of multi-family, commercial and industrial customers and a growing number
of residential  customers currently purchase their gas supplies from natural gas

                                       9


<PAGE>

marketers and then contract with the Company for local transportation, balancing
and other unbundled services. Since these customers are no longer reliant on the
Company for sales  service,  the quantity of gas that the Company must obtain to
meet remaining sales  customers'  requirements  has been reduced.  This trend is
likely to continue as state regulators  implement policies designed to encourage
customers to purchase their gas from suppliers  other than the  traditional  gas
utilities.

           PEAK-DAY CAPABILITY. The design criteria for the Company's gas system
assumes  an  average  temperature  of 0(0)F  for  peak-day  demand.  Under  such
criteria,  the Company  estimates that the  requirements  to supply its firm gas
customers would amount to approximately  1,754 MDTH of gas for a peak-day during
the 1998/99  winter  season and that the gas  available to the Company on such a
peak-day amounts to  approximately  2,033 MDTH. For the 1999/2000 winter season,
the  Company   estimates  that  the  peak-day   requirements   would  amount  to
approximately  1,789 MDTH and that the gas  available to the Company  amounts to
approximately  2,033  MDTH.  As of March 1, 1999,  the 1998/99  winter  peak-day
throughput to the Company's  customers was 1,511 MDTH, which occurred on January
14, 1999, at an average  temperature  of  22(degree)F,  representing  74% of the
Company's  peak-day  capability at that time.  The Company  expects that it will
have  sufficient gas available to meet the projected  requirements  for firm gas
customers  for the 1999/2000  winter  season.  The  Company's  firm gas peak-day
capability is summarized in the following table:

           PRODUCERS.  The  Company  purchases  natural  gas  for  sale  to  its
customers under contracts with suppliers located in domestic and Canadian supply
basins and arranges for its  transportation  to the Company's  facilities  under
firm long-term contracts with interstate pipeline companies.  During 1998, about
78% of the Company's  natural gas supply was available from domestic sources and
22% from Canadian  sources.  The Company has  available  under firm contract 750
MDTH per day of year-round and seasonal pipeline  transportation capacity to its
facilities in the New York City metropolitan area. Major providers of interstate
pipeline capacity and related services to the Company include:  Transcontinental
Gas Pipe Line Corporation, Texas Eastern Transmission Corporation,  Iroquois Gas
Transmission   System,   Tennessee  Gas  Pipeline   Company,   CNG  Transmission
Corporation and Texas Gas Transmission Company.

           STORAGE.  In order to meet higher winter demand, the Company also has
long-term  contracts  with  Transcontinental  Gas Pipe Line  Corporation,  Texas
Eastern   Transmission   Corporation,   Tennessee  Gas  Pipeline  Company,   CNG
Transmission Corporation, Equitrans, Inc., Hattiesburg First Reserve and Honeoye
Storage  Corporation,  for underground  storage  capacity of 58,935 MDTH for the
winter season, with 779 MDTH per day maximum deliverability.

           PEAKING SUPPLIES. In addition to the pipeline and storage supply, the
Company  supplements its winter supply with peaking supplies which are available
on the  coldest  days of the year to enable the  Company  to meet the  increased
requirements  of its  heating  customers  economically.  The  Company's  peaking
supplies include gas provided by the Company's two liquefied natural gas ("LNG")

                                       10
<PAGE>


plants   and   under   peaking   supply   contracts   with   four   cogeneration
facilities/independent  power  producers  located in its franchise area. For the
1998/99  winter  season,  the  Company has the  capability  to provide a maximum
peak-day  supply of 504 MDTH on  excessively  cold days.  The LNG plants  have a
storage capacity of approximately 2,053 MDTH and peak-day throughput capacity of
394 MDTH, or 19% of peak-day  supply.  The Company also has contract rights with
Trigen  Services   Corporation,   Brooklyn  Navy  Cogeneration   Partners,   LP,
Nissequogue  Cogen Partners and the New York Power Authority to purchase peaking
supplies with a maximum daily capacity of 110 MDTH and total  available  peaking
supplies during the winter season of 3,349 MDTH.

           GAS SUPPLY  MANAGEMENT.  During  1998,  the  Company  entered  into a
one-year  arrangement  with  Enron  whereby  Enron  provides  gas  supply  asset
management services for Brooklyn Union. Under the terms of this agreement, Enron
is  responsible  for managing  certain  aspects of Brooklyn  Union's  interstate
pipeline  transportation,  gas supply and storage. Enron also is responsible for
satisfying  certain of the  Company's  gas  supply  requirements;  however,  the
Company  remains  contractually  obligated  to its  gas  suppliers  and  has not
terminated  any  of  its  supply  and  delivery  contracts.   Pursuant  to  this
arrangement,  Enron  paid the  Company  a fee in 1998,  a  portion  of which was
credited  to the  Company's  gas  ratepayers,  and  obtained  the  right to earn
revenues  based upon its  management of the  Company's gas supply  requirements,
storage arrangements and off-system capacity.

           In 1998,  the Company  entered  into a one-year  alliance  with Coral
Energy Resources, L.P., a division of Shell Oil Company ("Coral"), whereby Coral
assists the Company in the origination,  structuring, valuation and execution of
energy-related  transactions  relating to Brooklyn  Union of Long Island and the
Company's  energy-management  services  undertaken  on behalf of LIPA. A sharing
agreement  exists  between the gas ratepayers and the Company for off-system gas
transactions   and  between  the  Company  and  LIPA  for  off-system   electric
transactions.  The Company's  share of the profits on such  transactions is then
shared with Coral.  The Company  also shares in revenues  arising  from  certain
transactions initiated by Coral.

           The arrangements with Enron and Coral are short-term agreements.  The
Company will continue to evaluate the  effectiveness  of these  arrangements and
ultimately  determine  the most  effective  management  approach in light of the
Company's  growth  objectives.  This approach  could be an  outsourcing  of this
management  function,  entering into a strategic  alliance with a third party to
jointly manage this activity, or internalizing the entire function.

           GAS  COSTS.  On a  Combined  Company  Basis,  gas costs for 1998 were
$702.7  million  and  reflect  warmer  than  normal  weather  during  the  year.
Variations in gas costs have little  impact on operating  results of the Company
since its current gas rate  structures  include gas adjustment  clauses  whereby
variations  between  actual gas costs and gas cost  recoveries  are deferred and
subsequently refunded to or collected from customers.

                                ELECTRIC SERVICES

OVERVIEW

           The  Company's   electric  services  primarily  consist  of  (i)  the
ownership and operation of oil- and gas-fired  generating  facilities located on
Long Island and the delivery of the power generated by these facilities to LIPA;
(ii) the management and operation of LIPA's T&D System; and (iii) the management
of LIPA's fuel and electric energy purchases and any off-system sales.

<PAGE>

           As more fully described  below,  the Company (i) provides to LIPA all
operation, maintenance and construction services relating to the Retained Assets
through a Management  Services  Agreement  (the "MSA");  (ii) supplies LIPA with
capacity  and energy  through a Power Supply  Agreement  (the "PSA") in order to
allow LIPA to provide  electricity  to its  customers on Long Island;  and (iii)
manages all aspects of the fuel supply for the Generating Facilities (as defined
below) as well as all  aspects  of the  capacity  and  energy  owned by or under
contract  to  LIPA  through  an  Energy   Management   Agreement   (the  "EMA").
Collectively,  the MSA,  PSA and EMA are  referred  to herein as the  "Operating
Agreements."

           In  addition,  on  January  28,  1999,  the  Company  entered  into a
definitive  agreement  with Con  Edison  to  purchase,  for  approximately  $597
million,   subject  to  adjustment,   the  2,168-megawatt   Ravenswood  electric
generating   facilities   located  in  Long  Island  City,   Queens,  New  York.
Consummation of this transaction is subject to various regulatory approvals, the
timing of which cannot be determined.

           During 1998,  on a Combined  Company  Basis,  electric  revenues were
$1.294 billion or 40% of the Company's  revenues and electric  operating  income
was $264.2 million,  excluding  special charges related to the Combination.  For
the period following  completion of the LIPA Transaction and ending December 31,
1998,  electric  revenues were $408.3 million and electric  operating income was
$10.7  million,  excluding  special  charges  related to the  Combination.  On a
Combined Company Basis, electric revenues were $2.481 billion and $2.466 billion
for 1997 and 1996, respectively,  and electric operating income was $645 million
and $642 million for 1997 and 1996, respectively.

GENERATION

           GENERATING  FACILITY  OPERATIONS.  The Company  owns and  operates an
aggregate  of  53  electric   generation   units  throughout  Long  Island  (the
"Generating  Facilities"),  20 of which can be powered  either by oil or natural
gas at the Company's  election.  In recent years,  the Company has  reconfigured
several of its facilities to enable them to burn either oil or natural gas, thus
enabling the Company to switch periodically between fuel alternatives based upon
cost and seasonal environmental requirements.

           The  following  table  indicates  the  1998  summer  capacity  of the
Company's steam generation  facilities and internal  combustion  ("IC") Units as
reported to the New York Power Pool ("NYPP"):

           The maximum  demand on the T&D System was 4,208  megawatts  ("MW") on
July 22, 1998,  representing 84% of the total available  capacity of 4,993 MW on
that day, which  included 769 MW of firm capacity  purchased from other sources.
By agreement  with the NYPP,  the Company is required to maintain,  on a monthly
and annual basis,  an installed  and  contracted  firm power reserve  generating
capacity  equal to at least 18% of its actual peak demand.  The Company  expects
that it will be able to  continue  to meet this NYPP  requirement.  However,  as
demand for capacity on Long Island  increases,  the Company  anticipates that it
will seek to meet  such  demand  through  the  acquisition  or  construction  of
additional generation facilities.

           POWER SUPPLY AGREEMENT.  The PSA provides for the sale to LIPA by the
Company of all of the capacity and, to the extent LIPA requests, energy from the
Generating  Facilities.  Capacity  refers to the ability to generate energy and,
pursuant to NYPP requirements, must be maintained at specified levels (including
reserves)  regardless  of the  source  and  amount  of  energy  consumption.  By
contrast, energy refers to the electricity actually generated for consumption by
customers.  Such sales of capacity and energy from the Generating Facilities are
made at cost-based  wholesale rates  regulated by the Federal Energy  Regulatory
Commission  ("FERC").  These rates may be  modified in the future in  accordance
with the terms of the PSA for (i) agreed upon labor and expense  indices applied
to the base year; (ii) a return of and on the capital invested in the Generating
Facilities;  and (iii) reasonably incurred expenses that are outside the control
of the Company.

           The PSA provides incentives and penalties for the Company to maintain
the output  capability  of the  Generating  Facilities,  as  measured  by annual
industry-standard  tests of operating  capability,  and plant  availability  and
efficiency.  These  combined  incentives  and  penalties may total as much as $4
million  annually.  In 1998 the Company  earned  approximately  $3.3  million in
incentives under the PSA.

           The PSA provides  LIPA with all of the capacity  from the  Generating
Facilities.  However,  LIPA  has no  obligation  to  purchase  energy  from  the
Generating  Facilities and is able to purchase energy on a least-cost basis from
all available  sources  consistent  with existing  transmission  interconnection
limitations of the T&D System.  Under the terms of the PSA, LIPA is obligated to
pay for capacity at rates which reflect a large  percentage of the overall fixed
cost  of  maintaining  and  operating  the  Generating  Facilities.  A  variable
maintenance charge is imposed for each unit of energy actually acquired from the
Generating  Facilities.  The term of the PSA is 15  years  and is  renewable  on
similar terms.  However,  the PSA provides LIPA the option of electing to reduce
or  "ramp-down"  the  capacity it purchases  from the Company  beginning in year
seven of the PSA,  in  accordance  with  agreed-upon  schedules.  In years seven
through ten of the PSA, if LIPA elects to ramp-down,  the Company is entitled to
receive  payment for 100 percent of the present  value of the  capacity  charges
otherwise  payable over the remaining  term of the PSA. If LIPA  ramps-down  the
generation  capacity  in years 11 through 15 of the PSA,  the  capacity  charges
otherwise  payable  by  LIPA  will  be  reduced  in  accordance  with a  formula
established in the PSA. If LIPA exercises its ramp-down option,  the Company may
use any capacity released by LIPA to bid on new LIPA capacity requirements or to
bid on LIPA's capacity  requirements to replace other ramped-down  capacity.  If
the Company continues to operate the ramped-down  capacity,  the PSA requires it
to use reasonable efforts to market the capacity and energy from the ramped-down
capacity  and to share any profits  with LIPA.  Capacity  and energy sold by the
Company from ramped-down  capacity must be transported over the T&D System,  and
the Company  will be  required  to pay LIPA's  standard  transmission  (and,  if
applicable,  distribution) rates for the service.  The PSA will be terminated in

                                       13

<PAGE>

the event that LIPA exercises its right to purchase,  at fair market value,  all
of the Generating Facilities in the twelve-month period beginning in May 2001.

           The Company has an inventory of sulfur  dioxide  ("SO2") and nitrogen
oxide ("NOx")  emission  allowances that may be sold to third party  purchasers.
The  amount of  allowances  varies  from year to year  relative  to the level of
emissions from the Generating Facilities,  which is greatly dependent on the mix
of natural  gas and fuel oil used for  generation  and the  amount of  purchased
power that is imported  onto Long  Island.  In  accordance  with the PSA, 33% of
emission  allowance  sales  revenue is kept by the  Company and the other 67% is
credited  to LIPA.  LIPA  also has a right of  first  refusal  on any  potential
emission allowance sales. Additionally,  the Company is bound by a memorandum of
understanding  with the New York State Department of Environmental  Conservation
which  prohibits the sale of SO2 allowances into certain states and requires the
purchaser to be bound by the same restriction,  which may affect the allowances'
market value.

TRANSMISSION AND DISTRIBUTION MANAGEMENT

           MANAGEMENT  SERVICES  AGREEMENT.  Under the MSA, the Company performs
day-to-day operations and maintenance of the T&D System, including,  among other
functions,  transmission and distribution facility operations, customer service,
billing and collection, meter reading, planning,  engineering, and construction,
all in accordance  with  policies and  procedures  adopted by LIPA.  The Company
furnishes  such  services  as an  independent  contractor  and does not have any
ownership or leasehold interest in the T&D System.

     In exchange for providing these  services,  the Company is entitled to earn
an annual management fee of $10 million and may also earn certain incentives, or
be responsible for certain penalties, based upon its performance. The incentives
provide  for  the  Company  to  retain  100% of the  first  $5  million  of cost
reductions and 50% of any additional cost reductions up to 15% of the total cost
budget.  Thereafter  all savings  accrue to LIPA.  The total cost budget for the
twelve month period ended December 31, 1998 was  approximately  $385.2  million.
The Company  also is  required to absorb any total cost budget  overruns up to a
maximum of $15 million in each contract year.

           In addition to the foregoing cost-based incentives and penalties, the
Company is eligible for  incentives  for  performance  above  certain  threshold
target levels and subject to disincentives  for performance  below certain other
threshold  levels,  with an  intermediate  band of  performance in which neither
incentives nor disincentives will apply, for system reliability,  worker safety,
and customer satisfaction.

           The term of the MSA is eight  years and  requires  that LIPA  solicit
bids in the  sixth  year of the term  for a new  management  services  agreement
beginning after the eighth year. Generally,  the Company is eligible to submit a
bid for such new management services agreement.

OTHER OPERATING AGREEMENTS

           ENERGY  MANAGEMENT  AGREEMENT.  Pursuant to the EMA,  the Company (i)
procures and manages fuel supplies for LIPA to fuel the  Generating  Facilities,
(ii) performs  off-system capacity and energy purchases on a least-cost basis to
meet  LIPA's  needs,  and  (iii)  makes  off-system  sales  of  output  from the
Generating Facilities and other power supplies either owned or under contract to
LIPA.  LIPA  is  entitled  to  two-thirds  of the  profit  from  any  off-system

                                       14


<PAGE>

electricity sales arranged by the Company.  The term for the service provided in
(i) above is fifteen  years,  and the term for the service  provided in (ii) and
(iii) above is eight years.

           In exchange for these  services,  the Company  earns an annual fee of
$1.5  million,  plus an  allowance  for certain  costs  incurred  in  performing
services under the EMA. The EMA further  provides  incentives for control of the
cost of fuel and  electricity  purchased on behalf of LIPA by the Company.  Fuel
and  electricity  purchase prices will be compared to regional price indices and
the Company will receive a payment from LIPA,  or be obligated to make a payment
to LIPA, for fuel and/or purchased  electricity  costs which are below or above,
respectively,  specified  tolerance bands. The total fuel purchase  incentive or
disincentive  can be no greater  than $5 million  annually  and the  electricity
purchase  incentive or disincentive can be no greater than $2 million  annually.
For the period ended  December 31, 1998, the Company earned an aggregate of $3.4
million in incentives under the EMA as well as revenue from off-system sales.

           OTHER  RIGHTS.  Pursuant  to other  agreements  between  LIPA and the
Company,  certain  future  rights have been granted to LIPA.  Subject to certain
conditions, these rights include the right for 99 years to lease or purchase, at
fair market value,  parcels of land and to acquire  unlimited access to, as well
as  appropriate  easements  at, the  Generating  Facilities  for the  purpose of
constructing  new  electric  generating  facilities  to be  owned by LIPA or its
designee. Subject to this right granted to LIPA, the Company will have the right
to sell or lease  property on or adjoining  the  Generating  Facilities to third
parties.  In  addition,  LIPA has the right to acquire a parcel at the  Shoreham
Nuclear Power Station site suitable as the terminus for a potential transmission
cable under Long Island Sound or the potential site of a new gas-fired  combined
cycle generating facility.

     The Company owns the common plant (such as administrative  office buildings
and computer  systems)  formerly  owned by LILCO and recovers  LIPA's  allocable
share of the  carrying  costs of such plant  through  the  agreements  described
above.  The Company has agreed to provide  LIPA,  for a period of 99 years,  the
right to enter into leases at fair market value for common plant or sub-contract
for  common  services  which it may  assign to a  subsequent  manager of the T&D
System.  The Company has also agreed (i) for a period of 99 years not to compete
with LIPA as a provider of transmission or distribution  service on Long Island;
(ii) that LIPA will share in synergy (I.E.,  efficiency) savings over a ten-year
period attributed to the Combination (estimated to be approximately $1 billion),
which  savings are  incorporated  into the cost  structure  under the  Operating
Agreements; and (iii) not to commence any tax certiorari case (until termination
of the  PSA)  challenging  certain  property  tax  assessments  relating  to the
Generating Facilities.

           GUARANTEES  AND  INDEMNITIES.  The Company and LIPA also have entered
into   agreements   providing   for  the   guarantee  of  certain   obligations,
indemnification against certain liabilities and allocation of responsibility and
liability for certain  pre-existing  obligations  and  liabilities.  In general,
liabilities  associated  with the  Transferred  Assets have been  assumed by the
Company and  liabilities  associated with the Retained Assets are borne by LIPA,
subject to certain specified exceptions. The Company has assumed all liabilities
arising from all  manufactured  gas plant  ("MGP")  operations  of LILCO and its
predecessors and LIPA has assumed certain liabilities relating to the Generating
Facilities  and  all  liabilities  traceable  to  the  business  and  operations
conducted by LIPA after completion of the Combination.

           An agreement also provides for an allocation of liabilities  that are
not  traceable to either the business or  operations  to be conducted by LIPA or

                                       15

<PAGE>

the Company after completion of the Combination  which relate to the assets that
were common to the operations of LILCO and/or shared services.  LIPA bears 53.6%
of the costs associated therewith and the Company bears the remainder.

                          GAS EXPLORATION & PRODUCTION

           Through its 64% equity  interest in The Houston  Exploration  Company
("THEC"),  an independent natural gas and oil company, the Company is engaged in
the  exploration,  development and  acquisition of domestic  natural gas and oil
properties.  THEC's offshore  properties are located in the Gulf of Mexico,  and
its onshore properties are located in South Texas,  South Louisiana,  the Arkoma
Basin of Oklahoma and Arkansas, East Texas and West Virginia.

           THEC was organized by the Company in 1985 to conduct  natural gas and
oil  exploration  and  production  activities.  It completed  an initial  public
offering  in 1996 and its  shares  are  currently  traded on the New York  Stock
Exchange  under the  symbol  "THX."  At March 22,  1999,  its  aggregate  market
capitalization was approximately $451.0 million (based upon the closing price on
the New York Stock Exchange on that date of $18.875).

           Information  with  respect  to  net  proved   reserves,   production,
productive wells and acreage, undeveloped acreage, drilling activities,  present
activities and drilling  commitments is contained in "Note 14.  Supplemental Gas
and Oil  Disclosures"  of the  Notes to the  Consolidated  Financial  Statements
included herein.

           During  1998,  on a  Combined  Company  Basis,  gas  exploration  and
production  revenues were $127.1  million,  and gas  exploration  and production
operating income was $15.3 million, excluding an impairment charge on its proved
gas reserves.  Set forth below is certain  selected  information with respect to
THEC:

           THEC  has  achieved   significant  growth  in  net  proved  reserves,
production  and revenues  over the past five years.  It has increased net proved
reserves at a compound  annual rate of 41% from 121 Bcfe at December 31, 1993 to
480 Bcfe at December 31, 1998. During this period,  annual production  increased
at a compound annual rate of 28% from 23 Bcfe in 1994 to 63 Bcfe in 1998. At the
close of 1998, daily  production  averaged 190 MMcfe per day. THEC's oil and gas
revenues have increased from $41.8 million in 1994 to $127.1 million in 1998.

           THEC  focuses  its  operations  offshore  in the Gulf of  Mexico  and
onshore in South Texas,  South Louisiana,  the Arkoma Basin, East Texas and West
Virginia.  The  geographic  focus  of its  operations  enables  it to  manage  a
comparatively  large asset base with  relatively  few  employees  and to add and
operate  production at relatively low incremental  costs.  THEC seeks to balance
its  offshore  and  onshore  activities  so that the lower risk and more  stable

                                       16

<PAGE>

production  typically  associated  with onshore  properties  complement the high
potential  exploratory  projects  in the Gulf of  Mexico by  balancing  risk and
reducing volatility. THEC's business strategy is to seek to continue to increase
reserves,  production and cash flow by pursuing internally  generated prospects,
primarily  in the Gulf of Mexico,  by  conducting  development  and  exploratory
drilling  on  its  offshore  and  onshore  properties  and by  making  selective
opportune acquisitions.

           OFFSHORE  PROPERTIES.  THEC  holds  interests  in  86  lease  blocks,
representing  439,896 gross (355,129 net) acres,  in federal and state waters in
the Gulf of Mexico,  of which 27 have current  operations.  THEC  operates 21 of
these blocks,  accounting for approximately  82% of THEC's offshore  production.
Over the past five years,  THEC has drilled 19 successful  exploratory wells and
14 successful development wells in the Gulf of Mexico, representing a historical
success rate of 65%. During 1998, THEC drilled two successful  exploratory wells
and one successful development well on its Gulf of Mexico properties. During the
same period,  THEC drilled five exploratory  wells and one development well that
were not successful.  THEC plans to drill  approximately  10 exploratory  wells,
along with limited development drilling, in the Gulf of Mexico in 1999.

           ONSHORE PROPERTIES.  THEC owns onshore natural gas and oil properties
representing  interests  in 1,179  gross (764 net) wells,  approximately  84% of
which THEC is the operator of record,  and 174,513  gross  (125,595  net) acres.
Over the past five years, THEC has drilled or participated in the drilling of 83
successful  development  wells  and  7  successful  exploratory  wells  onshore,
representing  a  historical  success rate of 78%.  During 1998,  THEC drilled or
participated  in  the  drilling  of 23  successful  development  wells  and  one
successful  exploratory well on its onshore properties.  During the same period,
THEC drilled or participated in the drilling of four development wells that were
not successful.
THEC plans to drill approximately 25 wells onshore in 1999.

           In November  1998,  the  Company  extended a $150  million  revolving
credit line to THEC (the "THEC Facility").  The THEC Facility matures January 1,
2000 and is convertible to equity if borrowings remain  outstanding at maturity.
The THEC Facility is  subordinated to THEC's bank credit facility and pari passu
to THEC's  senior  subordinated  notes.  As of December 31,  1998,  THEC had $80
million outstanding under the THEC Facility.

           On November  30,  1998,  THEC  acquired  from  Chevron  U.S.A.,  Inc.
offshore  producing  properties and facilities in the Mustang Island area of the
Gulf of Mexico.  The newly  acquired  properties are comprised of three adjacent
blocks,  with nine producing wells and three platforms.  The acquired properties
neighbor 19 undeveloped lease blocks and five producing blocks held by THEC. The
net purchase  price of $84.9 million was paid in cash and financed by borrowings
under the THEC Facility. THEC plans both exploratory and development drilling in
1999 on those properties.

           On  March  15  1999,  the  Company  and  THEC  entered  into a  joint
exploration  agreement (the "THEC Joint Venture") to explore for natural gas and
oil over a term of three  years  expiring  December  31,  2001.  The THEC  Joint
Venture may be  terminated  at the option of either  party at the end of a given
year.  Under  the  terms of this  agreement,  THEC  will  contribute  all of its
currently  undeveloped offshore leases to the THEC Joint Venture and the Company
will acquire 45% of THEC's working interest in all prospects to be drilled under
the THEC Joint  Venture and will commit up to $100 million per calendar  year to
explore and develop these leases.  THEC will retain a 55% interest in the leases
and will commit its proportionate share of the funds per calendar year necessary
for such year's exploration and development drilling program. Revenues generated

from this joint program will be shared between the Company and THEC according to
the respective  working interest  ownership of each entity.  THEC plans to drill
approximately 8-10 offshore  exploratory wells under the terms of the THEC Joint
Venture during 1999.

           The  Company   intends  to  continue  to  grow  its  exploration  and
production  investments in the Gulf region.  KeySpan  anticipates that THEC will
have capital expenditures of approximately $82 million in 1999. In addition, the
Company anticipates that it will invest  approximately $45 million  additionally
in exploration  and production  activities in 1999. Such amounts are expected to
consist primarily of contributions to the THEC Joint Venture.

                           ENERGY-RELATED INVESTMENTS

OVERVIEW

           The Company has investments in energy-related  businesses,  including
natural gas pipelines, midstream natural gas processing and gathering facilities
and gas storage  facilities in the Northeast  region of the United States and in
Canada and the United Kingdom.

           During 1998, on a Combined  Company  Basis,  net after-tax  loss from
energy-related   investments  was  $6.1  million,   and  the  Company's  capital
expenditures  in  energy-related  investments  were  $239.8  million,  which was
significantly higher than past years primarily due to the Company's $189 million
investment in certain midstream natural gas assets, as discussed below.

           The Company  owns an  approximately  20%  interest  in  Iroquois  Gas
Transmission  System L.P.  ("Iroquois"),  the  partnership  that owns a 374-mile
pipeline  which  currently  transports  892 MDTH of Canadian gas supply daily to
markets in the  Northeastern  United  States.  The  Company is also a shipper on
Iroquois and currently transports up to 135 MDTH of gas per day on the pipeline.

           The Company owns a 24.5% interest in Phoenix  Natural Gas ("Phoenix")
in Belfast,  Northern  Ireland and, in December 1998,  increased its interest in
The Premier Transco  Pipeline  ("Premier") from 24.5% to 50%. Phoenix is a newly
established gas distribution system serving the City of Belfast, which is in its
early  stages of  development  pursuant  to an  eight-year  program  of  capital
development  and line  extensions.  Premier is an 84-mile  pipeline  to Northern
Ireland from southwest Scotland that currently transports approximately 300 MDTH
of gas supply daily to markets in Northern Ireland.

           The Company has equity  investments in two gas storage  facilities in
the State of New York.

           In August 1998,  the Company  acquired a 25% interest in a venture to
develop the Cross Bay pipeline.  Upon  completion,  Cross Bay will transport gas
from  interstate  pipelines  in New  Jersey  to New York  City and Long  Island,
including supplying customers served by the Company. The new system is scheduled
to begin operating in November 2000.

           In  December  1998,  the Company  acquired a 50%  interest in certain
midstream  natural gas assets  owned by Gulf  Canada  Resources  Limited  ("Gulf
Canada") located in Western Canada. The purchased assets include interests in 14
processing   plants  and   associated   gathering   systems  which  can  process

                                       18

<PAGE>

approximately 1.4 Bcfe of natural gas daily, and associated  natural gas liquids
fractionation,  storage and  transportation  facilities.  The Company  paid Gulf
Canada $189 million for the equity  interest and agreed to provide a three-year,
$65 million loan to Gulf Canada.

           The Company's  business  strategy with respect to its  energy-related
investments is to acquire and maintain  interests in natural gas and natural gas
liquid gathering, processing,  transmission and storage facilities near areas of
rapid reserve  development or growing consumer  markets.  It is anticipated that
approximately $85 million will be invested in energy-related businesses in 1999,
a level of investment that could rise significantly in future years based on the
numerous potential domestic and international projects currently being pursued.

                             ENERGY-RELATED SERVICES

OVERVIEW

           The  Company  has  formed  non-regulated  subsidiaries  to market and
manage  natural  gas,  electricity,   and  consumer  products  and  services  to
residential,  commercial and industrial  customers,  including  those within the
Company's  traditional service  territories.  These  non-regulated  subsidiaries
which are currently in the start-up phase,  had revenues of $88.4 million and an
operating  loss of $10.2  million in 1998,  on a  Combined  Company  Basis.  The
Company  expects  to  invest   approximately   $57  million  in  1999  in  these
non-regulated subsidiaries.

           ENERGY  MARKETING.  The  Company  buys,  sells  and  markets  gas and
electricity and arranges for  transportation and related services to over 30,000
customers throughout the northeastern United States,  including those in the gas
service  territories of the Company.  In 1998,  the Company  established a joint
venture with Enron to market gas supply management  services to gas distribution
companies throughout the Northeastern United States.

           ENERGY  MANAGEMENT.  The Company owns, designs and/or operates energy
systems for  commercial  and  industrial  customers and provides  energy-related
services to clients in the New York City metropolitan  area.  Revenues have been
enhanced through the continued integration of an engineering firm.

           APPLIANCE  SERVICES.  The  Company  provides  various  technical  and
maintenance  services to  customers  throughout  the New York City  metropolitan
area,  including  maintaining and repairing  heating  equipment,  water heaters,
central  air  conditioners  and  other  appliances.  With over  100,000  service
contracts, the Company is the largest provider of these services in the State of
New York. In November 1998, the Company purchased Philip Fritze and Sons, one of
the largest heating,  ventilation and air conditioning  contractors in the State
of New Jersey.

           The Company's  energy-related  services  businesses  compete with the
marketing  and  management  operations  of both  independent  and  major  energy
companies in addition to electric utilities,  independent power producers, local
distribution companies and various energy brokers. As a result of the continuing
efforts to deregulate both the natural gas and electric industries, the relative
energy  cost  differences  among  different  forms of energy are  expected to be
reduced in the future.  Competition is based largely upon pricing,  availability
and  reliability  of supply,  technical  and  financial  capabilities,  regional
presence and experience.  The Company's energy-related services subsidiaries are
expected to enable the Company to take advantage of emerging  deregulated energy
markets for both gas and  electricity and the Company  anticipates  that it will

                                       19


<PAGE>

continue to target other  acquisitions  which also provide it with opportunities
to expand  those  services  both  within and  outside  its  traditional  service
territories.

REGULATION AND RATE MATTERS

                                    OVERVIEW

           Gas and electric public utility companies, and corporations which own
gas  and  electric  public  utility  companies  (I.E.,  public  utility  holding
companies)  may be subject to either or both state and  federal  regulation.  In
general,  state  public  service  commissions,  such as the NYPSC,  regulate the
provision of retail services, including the distribution and sale of natural gas
and electricity to consumers.  The Federal Energy Regulatory Commission ("FERC")
regulates interstate natural gas transportation and electric  transmission,  and
has jurisdiction over certain wholesale natural gas sales and wholesale electric
sales.  Public utility holding  companies,  especially  those with operations in
several  states,  are  regulated  by the SEC under the  Public  Utility  Holding
Company Act of 1935 ("PUHCA") and, to some extent, by state commissions, through
the  regulation  of  corporate,  financial  and  affiliate  activities of public
utilities.

           PUBLIC UTILITY HOLDING COMPANY REGULATION. KeySpan Energy is a public
utility holding company,  although it is exempt from most regulation under PUHCA
because  of  the  predominately  intrastate  character  of  its  public  utility
subsidiaries.  The only  provision  of PUHCA  from which  KeySpan  Energy is not
exempt is the  requirement  that any person must obtain advance SEC approval for
the acquisition of 5% or more of voting  securities issued by any public utility
company or public  utility  holding  company.  KeySpan Energy is also subject to
indirect  regulation  by the NYPSC in the form of  conditions  attached to NYPSC
orders  authorizing  the formation of the Company,  among other  matters.  Those
conditions  address the manner in which KeySpan  Energy  interacts  with its two
NYPSC-regulated  natural  gas  distribution  subsidiaries,  Brooklyn  Union  and
Brooklyn Union of Long Island.

                                NYPSC REGULATION

           NATURAL GAS UTILITIES. The NYPSC is the principal agency in the State
of New York which regulates, as "gas corporations,"  companies that own, operate
or manage pipelines and other facilities used to distribute or sell natural gas.
The NYPSC regulates the construction,  use and maintenance of intrastate natural
gas facilities, the retail rates, terms and conditions of service offered by gas
corporations, as well as matters relating to the quality, reliability and safety
of service.  The NYPSC also  regulates  the  corporate,  financial and affiliate
activities of gas  corporations.  Both Brooklyn Union and Brooklyn Union of Long
Island are gas corporations subject to the full scope of NYPSC regulation.

           Beginning in the mid-1980's, the NYPSC has taken a number of steps to
require  the  "unbundling"  of  natural  gas sales and other  services  from the
distribution of natural gas through pipelines, in order to encourage competition
among gas sellers and energy service  providers.  In 1985, the NYPSC ordered the
major gas  utilities  in the  state to offer  transportation  service  for large
volume  customers  who choose to  purchase  natural  gas from  other  suppliers.
Subsequently,  the NYPSC required that transportation  service be made available
to all  customers  beginning on May 1, 1996.  Brooklyn  Union of Long Island has
been providing a transportation  service option to all its customers since April
1996.  Brooklyn  Union has been  providing  a  transportation  option to all its
customers since May 1996.

                                       20

<PAGE>

           In April 1997,  the NYPSC  ordered gas  utilities to cease  providing
non-safety  related  appliance  repair  service  by no later  than May 1,  2000.
Brooklyn Union stopped providing these services in April 1998; Brooklyn Union of
Long Island will cease providing non-emergency appliance repair services on July
1, 1999.  Utility  affiliates can provide this service,  and the Company does so
through a subsidiary.

           In  November  1998,   the  NYPSC  issued  a  policy   statement  that
anticipated  that  natural gas  utilities  would cease sales of gas,  and become
transportation-only  providers, within three to seven years. Marketers which are
affiliated  with the natural gas  utilities  are permitted to compete for retail
natural  gas sales.  The  NYPSC's  policy  statement  envisions  proceedings  to
restructure  the  operations of natural gas utilities in order to facilitate the
achievement of the objectives  articulated in the policy statement.  The Company
is evaluating the policy statement and anticipates  making specific proposals to
the NYPSC in 1999.

           Brooklyn  Union  of  Long  Island  is  currently  operating  under  a
three-year  rate plan.  The rate plan  applies to the  period  December  1, 1997
through  November 30, 2000.  Under the plan, if Brooklyn  Union of Long Island's
earnings exceed 11.10%, it must credit back to certain customers 60% of earnings
up to 100 basis  points  above the 11.10% and 50% of any earnings in excess of a
12.10% return.  Both a customer  service and a safety and reliability  incentive
performance  program became  effective on December 1, 1997, with maximum pre-tax
return on equity penalties of 40 and 12 basis points, respectively,  if Brooklyn
Union of Long Island  fails to achieve  certain  performance  standards in these
areas.

           Brooklyn Union is currently  operating  under a multi-year  rate plan
that ends on September 30, 2002.  Brooklyn  Union,  like Brooklyn  Union of Long
Island,  is subject to an  earnings  sharing  provision,  under which it will be
required to credit to certain  customers  60% of any utility  earnings up to 100
basis points  above  specified  equity  return  levels  (other than any earnings
associated with discrete  incentives) and 50% of any utility  earnings in excess
of 100 basis points above such threshold levels. The threshold levels are 13.75%
for fiscal year 1998,  13.50% for fiscal years 1999,  2000 and 2001;  and 13.25%
for fiscal year 2002. A safety and reliability  incentive  mechanism  provides a
maximum 12 basis point pre-tax penalty return on common equity if Brooklyn Union
fails to achieve certain safety and  reliability  performance  standards,  and a
customer  service  incentive  performance  program with a maximum 40 basis point
pre-tax penalty return on equity.  With the exception of the  simplification  of
the customer  service  performance  standards and the imposition of the earnings
sharing  provisions,  the Brooklyn Union rate plan approved by the NYPSC in 1996
remains unchanged.

           As  part  of  the  settlement  agreement  approved  by the  NYPSC  in
connection with its approval of the Combination  (the  "Stipulation"),  Brooklyn
Union and  Brooklyn  Union of Long  Island  are  subject  to  certain  affiliate
transaction restrictions, cost allocation and financial integrity conditions and
a code of conduct  governing  affiliate  relationships.  These  restrictions and
conditions  eliminate  or  relax  many  restrictions  previously  applicable  to
Brooklyn  Union in such  areas as  affiliate  transactions,  use of the name and
reputation of Brooklyn Union by unregulated  affiliates,  common officers of the
Company, the utility subsidiaries and unregulated subsidiaries, dividend payment
restrictions, and the composition of the Board of Directors of Brooklyn Union.

           The Stipulation provides that, in order to achieve forecasted synergy
savings resulting from the Combination, one or more shared services subsidiaries
of the  Company  may be formed to  provide  to both  regulated  and  unregulated
operating subsidiaries, functions common to both utilities and their affiliates,
such as accounting,  finance, human resources, legal and information systems and
technology.

                                       21

           ELECTRIC  UTILITIES.  KeySpan Generation LLC ("KeySpan  Generation"),
KeySpan's  electric  generation  subsidiary,   is  not  subject  to  NYPSC  rate
regulation  because its sales of electricity are made  exclusively at wholesale;
however,  KeySpan  Generation  is subject to NYPSC  financial,  reliability  and
safety regulation.  As a wholesale  generator,  KeySpan Generation qualifies for
"lightened" regulatory treatment,  I.E. certain financial regulations are waived
or  applied  with  less  scrutiny  than  would be the  case for  fully-regulated
electric utilities.

                               FEDERAL REGULATION

           NATURAL GAS COMPANIES.  The FERC has jurisdiction to regulate certain
natural  gas sales for resale in  interstate  commerce,  the  transportation  of
natural gas in interstate commerce, and, unless an exemption applies,  companies
engaged in such activities.  The natural gas distribution activities of Brooklyn
Union and  Brooklyn  Union of Long Island and  certain  related  intrastate  gas
transportation  functions are not subject to FERC jurisdiction.  However, to the
extent that Brooklyn Union and Brooklyn Union of Long Island sell gas for resale
in interstate  commerce,  such sales are subject to FERC  jurisdiction  and have
been authorized by the FERC.

           The Company also owns an approximately  20% interest in Iroquois,  an
interstate  natural gas  pipeline  extending  from the  Canadian  border to Long
Island,  and 52% and 18.6% of the Honeoye  and  Steuben gas storage  facilities,
respectively.  Iroquois,  Honeoye and Steuben are fully regulated by the FERC as
natural gas companies.

           ELECTRIC  UTILITIES.  The FERC  regulates the sale of  electricity at
wholesale and the transmission of electricity in interstate commerce, as well as
certain corporate and financial activities of companies that are engaged in such
activities.

     KeySpan  Generation  is  subject to FERC  regulation  based on its sales of
electricity  at  wholesale  to LIPA under the PSA.  On  October 1, 1997,  a rate
application  was filed with the FERC which proposed rates that were designed for
KeySpan  Generation to recover $327.6 million from LIPA for the first year of an
approximately five-year rate plan with various adjustments, and to set the rates
for the  remainder of the  multi-year  rate period.  In December  1997,  KeySpan
Generation  and LIPA agreed  jointly to propose to FERC rates that would recover
$301.8 million in the first year of the multi-year  rate period and  adjustments
to set rates for the remaining years. LIPA, KeySpan Generation, and the Staff of
FERC  eventually  stipulated to setting rates designed to recover $300.5 million
in the first year with agreed-upon adjustments to set rates for the remainder of
the multi-year  rate period.  The only party opposed to this  stipulation is the
County of Suffolk. Parties submitted initial briefs to a FERC Administrative Law
Judge  ("ALJ") on December 8, 1998 and reply  briefs on January  15,  1999.  The
Company has not yet  received  the  decision  of the ALJ or a final  decision of
FERC.  Until such final decision,  rates are in effect subject to adjustment and
refund.  The FERC retains the ability in future  proceedings,  either on its own
motion or upon a complaint  filed with the FERC, to modify KeySpan  Generation's
rates,  either  upward or downward,  if the FERC finds that the public  interest
requires it to do so.

                          REGULATION IN OTHER COUNTRIES

           The  Company's  operations  in Northern  Ireland,  conducted  through
Premier and Phoenix, are subject to licensing by the Northern Ireland Department
of Economic  Development  and  regulation  by the U.K.  Department  of Trade and
Industry  (with  respect to the  subsea  and  on-land  portions  of the  Premier
pipeline) and the Northern Ireland Director  General,  Office for the Regulation
of  Electricity  and Gas (with  respect to the Northern  Ireland  portion of the
Premier pipeline and Phoenix's  operations  generally).  The licenses  establish
mechanisms for the establishment of rates for the conveyance and  transportation
of natural gas, and generally  may not be revoked  except upon long term notice.
Charges  for the  supply of gas by  Phoenix  are  largely  unregulated  unless a
determination is made of an absence of competition.

           The Company's  midstream natural gas processing  facilities in Canada
are subject to regulation by Canadian  provincial  authorities.  Such regulatory
authorities license the operations of the facilities and regulate safety matters
and certain changes in such facilities' operations.

ENVIRONMENTAL MATTERS

                                    OVERVIEW

           The  Company's  ordinary  business  operations  subject it to various
federal,   state  and  local  laws,  rules  and  regulations  dealing  with  the
environment,  including  air,  water,  and  hazardous  waste,  and its  business
operations  are  regulated  by  various  federal,   regional,  state  and  local
authorities,  including the United States  Environmental  Protection Agency (the
"EPA") and the New York State Department of Environmental  Conservation ("DEC").
These requirements govern both the normal, ongoing operations of the Company and
the  remediation  of  contaminated   properties  historically  used  in  utility
operations.  Potential  liabilities  associated  with the  Company's  historical
operations may be imposed  without regard to fault,  even if the activities were
lawful at the time they occurred.

           Ensuring  continuing  compliance with environmental  requirements may
require  significant  expenditures for capital  improvements or modifications in
some areas.  Total  capital  expenditures  for  environmental  improvements  and
related  studies  amounted  to  approximately  $1.6  million  for the year ended
December  31,  1998,  and are  expected  to be $2.3  million for the year ending
December 31, 1999.

           Except  as set forth  below,  no  material  proceedings  relating  to
environmental  matters have been  commenced or, to the knowledge of the Company,
are contemplated by any federal,  state or local agency against the Company, and
the Company is not a defendant  in any material  litigation  with respect to any
matter relating to the protection of the environment.  The Company believes that
its operations are in substantial  compliance with  environmental  laws and that
requirements  imposed  by  environmental  laws are not likely to have a material
adverse  impact upon the Company.  The Company  believes that all material costs
incurred with respect to environmental requirements will be recoverable from its
customers.  The  Company is  pursuing  claims  against  insurance  carriers  and
potentially  responsible  parties  which  seek the  recovery  of  certain  costs
associated with the investigation and remediation of contaminated properties.

           AIR.  Federal,  state and local laws currently  regulate a variety of
air emissions from new and existing electric  generating plants,  including SO2,
NOx,  opacity and  particulate  matter and,  in the  future,  may also  regulate
emissions of fine  particulate  matter,  hazardous  air  pollutants,  and carbon

                                       23
<PAGE>

dioxide. The Company has submitted timely applications for permits in accordance
with the requirements of Title V of the 1990 amendments to the Federal Clean Air
Act ("CAA").  Final permits have been issued for all of the  Company's  electric
generating facilities with the exception of the Far Rockaway facility,  which is
pending.  The permits allow the Company's electric generating plants to continue
to operate without any additional significant expenditures,  except as described
below.

           The Company's  generating  facilities are located within a CAA severe
ozone  non-attainment  area,  and are  subject  to the Phase I, II,  and III NOx
reduction  requirements  established under the Ozone  Transportation  Commission
("OTC")  memorandum  of  understanding.  The  Company's  investments  in  boiler
combustion modifications and the use of natural gas firing at its steam electric
generating  stations  has  enabled  the  Company  to  achieve  the NOx  emission
reductions  required  under  Phase  I and  II  in a  cost-effective  manner.  In
addition,  software  and  equipment  upgrades  of  approximately  $1 million for
continuous  emissions  monitors ("CEM") may be required in 1999-2000 to meet EPA
requirements  for the NOx allowance  tracking/trading  program and certain other
regulatory changes affecting the operation of CEM systems. The Company currently
estimates  that it may be required to spend  between $10 million and $35 million
by the year 2003 for additional  pollution  control equipment to achieve the OTC
Phase III NOx reduction  requirements and/or new requirements  imposed under the
EPA NOx state implementation plan, depending on the actual level of NOx emission
reductions  which are required when pending  regulations  are implemented by the
State of New York.

           WATER. The Company  possesses  permits for its generating units which
authorize  discharges  from  cooling  water  circulating  systems  and  chemical
treatment  systems.  Several of these permits are being renewed;  one or more of
the new permits are expected to require  biological  monitoring  to determine if
the  cooling  water  intake  structures  meet  the  best  available   technology
requirements of the Federal Clean Water Act ("CWA") for the protection of marine
life.

           On behalf of LIPA,  the Company  provides  management  and operations
support for the LIPA-Connecticut  Light and Power Company electric  transmission
cable  system  located  under the Long  Island  Sound (the "Sound  Cable").  The
Connecticut   Department  of  Environmental   Protection  ("DEP")  and  the  DEC
separately have issued Administrative Consent Orders ("ACOs") in connection with
releases  of  insulating  fluid  from the  Sound  Cable.  The ACOs  require  the
submission of a series of reports and studies describing cable system condition,
operation  and  repair  practices,   alternatives  for  cable   improvements  or
replacement, and environmental impacts associated with prior leaks of fluid into
the  Long  Island  Sound.  Compliance  activities  associated  with the ACOs are
ongoing.

                      REMEDIATION OF CONTAMINATED PROPERTY

           SUPERFUND  SITES.  Federal and New York State  Superfund  laws impose
liability,  regardless of fault,  upon  generators of hazardous  substances  for
costs associated with remediating  contaminated  property.  In the course of its
business operations,  the Company generates materials which are subject to these
laws.  From time to time,  the Company  has  received  notices  under these laws
concerning  possible claims with respect to sites at which hazardous  substances
generated  by the Company and other  potentially  responsible  parties  ("PRPs")
allegedly were disposed.

                                       24
<PAGE>


           The DEC has  notified the  Company,  pursuant to the State  Superfund
program,  that the  Company may be  responsible  for the  disposal of  hazardous
substances at the Huntington/East Northport Site, a municipal landfill property.
The DEC investigation is in its preliminary stages, and the Company currently is
unable to estimate its share,  if any, of the costs required to investigate  and
remediate this site.

           MANUFACTURED   GAS  PLANT  SITES.  The  Company  or  its  predecessor
entities,  including  Brooklyn Union and LILCO,  historically  owned or operated
several  former MGP sites.  Operations  at these  plants in the late  1800's and
early  1900's may have  resulted in the release of hazardous  substances.  These
former sites have been identified to the DEC for inclusion on appropriate  waste
site inventories.  In certain  circumstances,  former MGP sites can give rise to
environmental cleanup responsibilities for the Company.

           The  Company  has  several   former  MGP  sites  that  will   require
investigation and/or remediation.  In 1995, the Company executed an ACO with the
DEC which addressed the  investigation  and remediation of the Brooklyn  Borough
Works site in Coney Island,  Brooklyn.  In 1998, the Company executed an ACO for
the investigation and remediation of the Clifton MGP site in Staten Island. Both
of these properties are owned by the Company.  The City of New York has notified
the Company that a property  now owned by the City which was formerly  owned and
operated  by a  Brooklyn  Union  predecessor,  the  Citizen's  Site,  should  be
investigated.  The  Company  has  submitted  an  investigation  study  plan  and
requested  cost sharing for this property with the City. The Company is awaiting
the City's response.  Finally, the DEC notified the Company in 1998 that two MGP
sites  previously  owned by LILCO would  require  remediation  under the State's
Superfund  program;  pending  discussions  with DEC on those and four additional
former LILCO sites are expected to result in the issuance of additional  ACOs in
the near future.

           The final end uses for these sites and acceptable  remediation  goals
have not been determined in the ACOs. In addition, investigation may be required
at other former MGP sites before  determinations  can be made regarding the need
for or scope of potential remediation at these locations.  Based upon activities
conducted to date,  the Company  estimates  the minimum cost of its  MGP-related
environmental cleanup activities will be approximately $130 million; that amount
has been  accrued  by the  Company  as an  environmental  liability.  The actual
MGP-related  costs  may be  substantially  higher,  depending  upon  remediation
experience,  selected end use for each site, and actual environmental conditions
encountered.

           The  NYPSC-approved  rate plans for Brooklyn Union and Brooklyn Union
of Long Island  provide for the recovery of such costs.  The Brooklyn Union rate
plan provides,  among other things,  that if the total cost of investigation and
remediation  varies from that which is  specifically  estimated for a site under
investigation  and/or remediation,  then Brooklyn Union will retain or absorb up
to 10% of the  variation.  Under prior rate orders,  Brooklyn  Union has already
recovered costs  associated  with certain MGP sites.  The Brooklyn Union of Long
Island  rate plan  provides  for the  complete  recovery  of  investigation  and
remediation  costs.  At December 31, 1998, the Company has reflected a remaining
regulatory  asset of $100  million  of which  $18  million  is  associated  with
Brooklyn  Union sites and $82 million is associated  with Brooklyn Union of Long
Island sites. Expenditures incurred to date by Brooklyn Union and Brooklyn Union
of Long Island with respect to MGP-related  activities total $8.7 million and $5
million, respectively.

           Periodic discussions by the Company with insurance carriers and third
parties  for  reimbursement  of  some  portion  of MGP  site  investigation  and
remediation  costs  continue.  In December 1996,  LILCO filed a complaint in the
United  States  District  Court for the  Southern  District of New York  against
fourteen  insurance  companies  that  issued  general  comprehensive   liability
policies to LILCO. In January 1998, LILCO commenced a similar action against the
same and additional insurance companies in New York State Supreme Court, and the
federal court action subsequently was dismissed.  The outcome of this proceeding
cannot yet be determined.  In addition,  Brooklyn  Union is in discussions  with
insurance carriers regarding the possible  resolution of coverage claims related
to MGP site investigation and remediation activities.

ITEM 2.  PROPERTIES

           Information with respect to the Company's material properties used in
the conduct of its business is set forth in, or  incorporated  by reference  in,
Item 1 hereof.  Except where otherwise specified,  all such properties are owned
or,  in the  case  of  certain  rights  of way  used in the  conduct  of its gas
distribution  business,  held  pursuant  to  municipal  consents,  easements  or
long-term  leases,  and in the  case  of oil  and  gas  properties,  held  under
long-term  mineral leases. In addition to the information set forth therein with
respect to  properties  utilized by each business  segment,  the Company owns or
leases a variety  of office  space  used for  administrative  operations  of the
Company.  In the  case of  leased  office  space,  the  Company  anticipates  no
significant  difficulty in leasing  alternative space at reasonable rates in the
event of the expiration,  cancellation or termination of a lease relating to the
Company's leased properties.

ITEM 3.  LEGAL PROCEEDINGS

           From  time  to  time,   the  Company  is  subject  to  various  legal
proceedings  arising  out of the  ordinary  course  of its  business.  Except as
described  below,  the Company does not consider any of such  proceedings  to be
material to its business or likely to result in a material adverse effect on its
results of operations or financial condition.

           Subsequent to the closing of the Combination,  former shareholders of
LILCO  commenced 13 class action  lawsuits in the New York State Supreme  Court,
Nassau County, against the Company and each of the former officers and directors
of LILCO.  These  actions were  consolidated  in August 1998.  The  consolidated
action  alleges that, in connection  with certain  payments LILCO had determined
were payable in connection  with the  Combination  to LILCO's  chairman,  and to
former officers of LILCO (the  "Payments"):  (i) the named  defendants  breached
their  fiduciary  duty  owed to LILCO  and KSE  former  and/or  current  Company
shareholders as a result of the Payments;  (ii) the named defendants intended to
defraud  such  shareholders  by means of  manipulative,  deceptive  and wrongful
conduct, including materially inaccurate and incomplete news reports and filings
with the SEC;  and (iii)  the named  defendants  recklessly  and/or  negligently
failed to disclose material facts associated with the Payments.

                                       29
<PAGE>


           In addition, three shareholder derivative actions have been commenced
pursuant to which such  shareholders  seek the return of the Payments or damages
resulting  from among other things,  an alleged  breach of fiduciary duty on the
part of the former  LILCO  officers  and  directors.  One action was  brought on
behalf of LILCO in federal  court.  The Company  moved to dismiss this action in
September  1998.  The other two actions were brought on behalf of the Company in
New York  State  Supreme  Court,  Nassau  County.  In one of these  state  court
actions,  the Company's  directors  and the  recipients of the Payments are also
named as defendants.

           Finally,  two class  action  securities  suits  were filed in federal
court alleging that certain officers and directors of LILCO violated the federal
securities  laws by failing to  properly  disclose  that the  Combination  would
trigger the Payments. These actions were consolidated in October 1998.

           On March 17, 1999, the Company  signed a Memorandum of  Understanding
to settle the  above-referenced  actions,  except the federal  court  derivative
action,  in exchange for (i) $7.9 million to be  distributed  (less  plaintiffs'
attorneys  fees) to former  LILCO and KSE  shareholders  and (ii) the  Company's
agreement to implement certain corporate  governance and executive  compensation
procedures.  The entire $7.9 million  settlement  commitment will be funded from
insurance.  The parties  intend to submit the  settlement  to the Nassau  County
Supreme  Court  for  its  review  and  approval.  If  that  Court  approves  the
settlement,  the parties will then make an  application to the federal court for
an order  and  final  judgment,  dismissing  the three  federal  court  actions,
including the federal court derivative action, based, among other things, on the
binding effect of the state court judgment.

           In addition to the  above-mentioned  actions,  a class action lawsuit
has also been filed in the New York State Supreme Court,  Suffolk County, by the
County of Suffolk against LILCO's former officers and/or  directors.  The County
of Suffolk  alleges that the Payments  were  improper,  and seeks to recover the
Payments  for the benefit of Suffolk  County  ratepayers.  The Company  moved to
consolidate this action with the above-mentioned  consolidated action in October
1998.

           In October  1998,  the County of Suffolk and the Towns of  Huntington
and Babylon commenced an action against LIPA, the Company,  the NYPSC and others
in the United States  District  Court for the Eastern  District of New York (the
"Huntington Lawsuit").  The Huntington Lawsuit alleges, among other things, that
LILCO  ratepayers  (i) have a property  right to receive or share in the alleged
capital gain that resulted from the transaction with LIPA (which gain is alleged
to be at least $1  billion);  and (ii)  that  LILCO  was  required  to refund to
ratepayers the amount of a Shoreham-related  deferred tax reserve (alleged to be
at least $800 million)  carried on the books of LILCO at the consummation of the
LIPA transaction.  In December 1998, the plaintiffs amended their complaint. The
amended  complaint  contains  allegations  relating to the Payments and adds the
recipients  of the  Payments as  defendants.  In January  1999,  the Company was
served with the amended complaint.

           Finally,  certain other  proceedings have been commenced  relating to
the  Payments  and  disclosures  made  by  LILCO  with  respect  thereto.  These
proceedings include  investigations by the New York State Attorney General,  the
NYPSC and LIPA, joint hearings conducted by two committees of the New York State
Assembly, and an informal,  non-public inquiry by the SEC. In December 1998, the
Company  settled with LIPA and the NYPSC.  The  agreement  includes a payment of
$5.2  million  by the  Company  to LIPA  that  will  be  used by LIPA to  supply
postage-paid  bill return  envelopes to customers for the next three years.  The
Company also agreed to fully  reimburse and indemnify LIPA for costs incurred by

                                       30
<PAGE>

LIPA, amounting to approximately  $765,000,  for attorneys and other consultants
involved in the  investigation.  Such amounts are not covered by insurance.  The
Company  is  cooperating  fully  with the  investigations  of the New York State
Attorney  General and the SEC. To date,  no action has been taken  either by the
New York State Attorney General or the SEC.

           At this time the  Company is unable to  determine  the outcome of the
ongoing proceedings, or any of the remaining lawsuits described above.

           In May 1995,  eight  participants of LILCO's  Retirement  Income Plan
("RIP") filed a lawsuit against LILCO, the RIP and Robert X. Kelleher,  the Plan
Administrator,  in the United States District Court for the Eastern  District of
New York (Becher,  et al. v. Long Island Lighting  Company,  et al.). In January
1996,  the Court ordered that this action be maintained as a class action.  This
proceeding arose in connection with the plaintiffs' withdrawal, approximately 25
years ago, of contributions made to the RIP, thereby resulting in a reduction of
their pension benefits.  The plaintiffs are now seeking,  among other things, to
have these  reduced  benefits  restored to their pension  accounts.  In November
1997, the Company filed a motion for partial summary  judgment with the District
Court.  On April 28, 1998,  the Court denied the Company's  motion and permitted
the Company to file a further motion for partial summary  judgment on additional
grounds.  On January 27, 1999,  the Company  entered a stipulation of settlement
which  was  filed  with  the  Court  pursuant  to  which  the  Company  will pay
approximately  $8 million,  a substantial  portion of which is recoverable  from
LIPA. The settlement is subject to court approval.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

           No matters were submitted to a vote of the Company's security holders
during the last quarter of the nine-month period ended December 31, 1998.

ITEM 7. MANAGEMENT'S  DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

MarketSpan  Corporation d/b/a KeySpan Energy (the "Company") is the successor to
Long Island  Lighting  Company  ("LILCO") as a result of a transaction  with the
Long Island Power Authority ("LIPA") (the "LIPA  Transaction") and following the
acquisition (the "KeySpan  Acquisition") of KeySpan Energy Corporation  ("KSE").
Both  transactions  occurred on May 28,  1998.  (See Note 2 to the  Consolidated
Financial  Statements,  "Sale of LILCO  Assets,  Acquisition  of KeySpan  Energy
Corporation  and  Transfer  of  Assets  and  Liabilities  to  the  Company"  for
additional  information.)  The Company is a  "predominately  intrastate"  public
utility holding company exempt from most of the provisions of the Public Utility
Holding Company Act of 1935, as amended.

Further,  subsequent  to these events,  the Company  changed its fiscal year end
from March 31 to December 31. Current period consolidated results of operations,
therefore,  are reported for the nine month  transition  period April 1, 1998 to
December 31, 1998 (the "Transition  Period").  The Transition Period consists of
the following: (i) the period April 1, 1998 through May 28, 1998, which reflects
the results of LILCO prior to the LIPA Transaction and KeySpan Acquisition;  and
(ii) the period May 29, 1998 through  December 31, 1998,  which  represents  the
results of the fully  consolidated  Company,  which  includes  all KSE  acquired
companies,  KeySpan Gas East  Corporation  d/b/a  Brooklyn  Union of Long Island
("Brooklyn Union of Long Island"),  which provides gas distribution  services on
Long Island and other  subsidiaries  providing  services  to LIPA under  various
services  agreements with LIPA. As required under purchase accounting rules, the
results for periods prior to May 29, 1998 reflect  results of LILCO only, and do
not include results of KSE.

As discussed in more detail below,  the Transition  Period being reported is not
comparable  either in time frame or composition  of the Company's  operations to
any prior  historical  period.  The analysis that follows is an  explanation  of
consolidated   results  of  operations  during  the  Transition  Period  and  an
explanation  of results of operations  applicable to the operations of LILCO for
the twelve  month  periods  ended March 31, 1998 and 1997 and December 31, 1996.
Further,  the results of operations reported herein are not indicative of future
results or operating trends.

EARNINGS

Consolidated  results  for the  Transition  Period  reflected  a loss of  $195.5
million,  or $1.34 per share. During the Transition Period, the Company incurred
substantial  non-recurring  charges associated with the LIPA Transaction.  These
non-recurring charges principally reflected the following: taxes associated with
the sale of assets  (the  "Transferred  Assets")  to the  Company  by LIPA;  the
write-off of certain regulatory assets that were no longer recoverable under the
various LIPA agreements;  and other transaction costs incurred to consummate the
LIPA  Transaction.  These charges were partially offset by tax benefits relating
to the deferred  federal  income taxes  necessary to account for the  difference
between the carryover  basis of the Transferred  Assets for financial  reporting
purposes and the new  increased  tax basis,  and tax benefits  recognized on the
funding  of  certain  postretirement   benefits.   These  non-recurring  charges
associated with the

                                       33
<PAGE>




LIPA Transaction were $107.9 million after-tax, or $0.74 per share.

Further, during the Transition Period, the Company also incurred special charges
amounting to $83.5 million after-tax,  or $0.57 per share. These items were: (i)
a $42  million  after-tax,  or $0.29 per share,  charge for an early  retirement
program  implemented  in  December  1998 in which  approximately  600  employees
participated;  and (ii) a $41.5 million  after-tax,  or $0.28 per share,  charge
associated  with  the  write-off  of  a  customer-billing  system  that  was  in
development.

Also,  in December  1998,  the Company made a $20 million  donation ($13 million
after-tax,  or  $0.09  per  share)  to  establish  the  KeySpan  Foundation,   a
not-for-profit  philanthropic  foundation  that  will  make  donations  to local
charitable  community  organizations.   Earnings  also  reflected  an  after-tax
non-cash  impairment charge recorded in December 1998 of $54.1 million, or $0.37
per  share,  which  represents  the  Company's  share of the  impairment  charge
recorded  by  its  gas  exploration  and  production  subsidiary,   The  Houston
Exploration Company ("THEC"),  to recognize the effect of low wellhead prices on
its valuation of proved gas reserves.

Consolidated income available for common stock,  excluding the non-recurring and
special charges discussed above, by reporting segment, for the Transition Period
and for the twelve months ended March 31, 1998 and 1997 and December 31, 1996 is
set forth in the following summary:

</TABLE>

The  Gas  Distribution  segment  consists  of The  Brooklyn  Union  Gas  Company
("Brooklyn  Union") and Brooklyn  Union of Long Island,  the  Company's  two gas
distribution  subsidiaries.  These subsidiaries provide natural gas to customers
in the New York City boroughs of Brooklyn, Queens and Staten Island and the Long
Island  counties  of Nassau and  Suffolk and the  Rockaway  Peninsula  of Queens
County,  respectively.  Gas Distribution  segment  earnings,  excluding  special
charges for the Transition Period, reflected the fact that gas utility customers
received the benefit of synergy  savings-related rate reductions,  authorized by
the Public Service Commission of the State of New York ("NYPSC"), before synergy
savings could begin to be achieved through cost reduction measures.  The Company
expects that the effect of these rate reductions will begin to be offset in


                                       34
<PAGE>




fiscal 1999 as synergy  savings are realized  through cost  reduction  measures,
principally  the early  retirement  program  implemented in December 1998.  Most
importantly,  earnings for the  Transition  Period do not include  earnings from
heating  season  operations  (months of January  through March) when the Company
realizes the major portion of its gas related earnings.

The Electric Services segment consists of subsidiaries that: (i) own and operate
oil and gas-fired  generating  facilities located on Long Island and deliver the
power  generated by these  facilities  to LIPA;  (ii) manage and operate  LIPA's
transmission and distribution  ("T&D") system;  and (iii) manage LIPA's fuel and
electric purchases and any off-system sales.  Earnings for the Electric Services
segment for the period May 29, 1998 through December 31, 1998, excluding special
charges,  reflected  service-fees under various service contracts with LIPA. The
Company's  operating  margins  under  such  arrangements  are lower  than  those
experienced prior to the LIPA  Transaction,  reflecting the change in the nature
of the Company's Electric Services business.

Earnings for Electric Services for the period April 1, 1998 through May 28, 1998
were positively impacted by a change in the method of recording the monthly Rate
Moderation Component ("RMC")  amortization.  As a result of this change, for the
period April 1, 1998 through May 28, 1998,  the Company  recorded  $51.5 million
more of non-cash  RMC credits to income,  or $33.5  million  after-tax,  than it
would have under the previous method. For a further  discussion,  see "Operating
Expenses."

The Gas Exploration and Production  segment consists of the Company's 64% equity
interest in THEC, an independent  natural gas and oil  exploration  company with
properties  located in the Gulf of Mexico,  Texas,  the Arkoma Basin of Oklahoma
and Arkansas,  South Louisiana and West Virginia.  Earnings  associated with Gas
Exploration  and  Production,  excluding  special  charges,  were  significantly
affected by low gas prices during the Transition Period and increased  operating
expenses due  primarily to increased  production  activity.  See "Revenues - Gas
Exploration and Production" for further discussion.

The Energy Related  Investments  segment primarily consists of the Company's 20%
investment  in the  Iroquois  Gas  Transmission  System LP,  investments  in The
Premier  Transco  Pipeline  and  Phoenix  Natural  Gas in  Northern  Ireland and
investments  in certain  midstream  natural gas assets in Western  Canada  owned
jointly with Gulf Canada Resources  Limited.  The Company recently has increased
its investment in The Premier Transco  Pipeline,  a gas pipeline  extending from
Scotland to  Northern  Ireland,  from a 24.5%  interest  to a 50%  interest.  In
addition,  the Company has a 24.5%  interest in Phoenix  Natural  Gas,  which is
expanding and refurbishing  the gas distribution  system that serves the City of
Belfast in Northern Ireland. Results from these investments reflect the start-up
nature of their operations,  while results relating to the Company's  investment
in the Iroquois Gas  Transmission  System LP are  consistent  with  management's
expectations. The Company completed its acquisition of a 50% interest in certain
midstream  natural gas assets in Western Canada in December 1998, and therefore,
earnings from this investment will begin to be realized in 1999. (See "Liquidity
and Capital Resources" for additional information.) Results also reflected costs
of approximately  $5.2 million after-tax to settle certain contracts  associated
with the sale of the

                                       35

<PAGE>




Company's  domestic  cogeneration  investments and fuel  management  operations,
which took place in 1997.

The Company's Energy Related Services segment primarily  includes KeySpan Energy
Management Inc. ("KEM"), KeySpan Energy Services Inc. ("KES") and KeySpan Energy
Solutions,  LLC ("KESol").  KEM provides a variety of technical and  maintenance
services to customers that operate commercial and industrial  facilities located
primarily within the New York City metropolitan area. Results from operations of
KEM were  profitable  during the  Transition  Period and reflected the continued
integration of companies acquired during the past two years. KES markets gas and
electricity, and arranges transportation and related services, largely to retail
customers,  including  those  served  by  the  Company's  two  gas  distribution
subsidiaries.  KES  incurred  losses  related  to  the  start-up  nature  of its
operations during the Transition Period. Results from operations of KESol, which
provides appliance repair service to residential  customers primarily within the
Company's  service  territory,  were also  unprofitable  during  the  Transition
Period.  The Company will  continue to realign these  non-utility  operations to
maximize  earnings  potential,  and  where  appropriate,   possibly  discontinue
non-profitable activities.

Results  reflected in the Other  segment,  excluding  special  charges,  include
interest income earned on investments from the proceeds of the LIPA Transaction,
offset, in part, by costs incurred by the corporate and administrative  areas of
the Company that have not been allocated to the various business segments.

Gas  Distribution  results were  affected by warmer than normal  weather for the
twelve months ended March 31, 1998 and 1997.  Gas  Distribution  results for the
year ended  December  31,  1996 were  positively  affected by colder than normal
weather,  a 3.2% rate  increase  which  became  effective  December  1, 1995 and
increased  off-system sales. Results from electric operations for the year ended
March  31,  1998  were  positively  affected  by the  change  in the  method  of
amortizing the RMC to eliminate the effects of seasonality on monthly  operating
income (See "Operating  Expenses" for additional  details on the RMC).  Earnings
for the twelve  months ended March 31, 1997 and for the year ended  December 31,
1996 were favorably  affected by the benefits derived from increased  investment
in electric  plants,  continued  efforts to reduce  operations  and  maintenance
expenses and the use of cash generated by operations to retire maturing debt.

GAS DISTRIBUTION
Gas  Distribution  revenues  for the  Transition  Period  were  impacted by rate
reductions which were reflected at the time of the KeySpan Acquisition. Brooklyn
Union  reduced  rates to its core  customers by $23.9 million on an annual basis
effective  May 29, 1998 and Brooklyn  Union of Long Island  reduced its rates to
core customers by $12.2 million  annually  effective  February 5, 1998 and by an
additional  $6.3  million  annually  effective  May 29, 1998.  Gas  Distribution
revenues for the Transition  Period do not include  revenues from heating season
operations (January through March). In addition,  revenues of Brooklyn Union are
not  reflected  for  periods  prior to the KeySpan  Acquisition.  The effects of
weather on gas  distribution  revenues  are  largely  mitigated  by the  weather
normalization  adjustment  included  in the  tariffs  of both  gas  distribution
utilities.  The weather  normalization  adjustment contained in Brooklyn Union's
tariff provides for the Company to retain or absorb 12.8% of differences between
actual margin  revenues and margin  revenues that would be produced under normal
weather conditions.  The weather normalization  adjustment contained in Brooklyn
Union  of Long  Island's  tariff  requires  the  Company  to  retain  or  absorb
variations  in margin  revenues to the extent that  actual  heating  degree days
experienced during a billing cycle vary from normal heating degree days for that
cycle by 2.2%.

Gas  Distribution  revenues for the twelve  months ended March 31, 1998 and 1997
and  December  31,  1996  reflected  the  continued  growth in the number of gas
heating  customers in all periods.  However,  Gas Distribution  revenues for the
twelve  months ended March 31, 1998 and 1997 were affected by warmer than normal
weather  during both periods.  Revenues for the twelve months ended December 31,
1996 reflected the effects of colder than normal weather during that time period
as well as the growth in the number of gas heating  customers.  Gas Distribution
revenues for the twelve months ended December 31, 1996 also reflected a 3.2% gas
rate increase that became effective on December 1, 1995.

                                       37

GAS EXPLORATION AND PRODUCTION
Gas Exploration and Production  revenues reflected the continued  development of
natural  gas  properties  acquired  by THEC  during  the past three  years.  The
benefits  derived from  increased  production  levels,  however,  were offset by
decreases in average realized prices. In 1998, production was approximately 62.8
billion cubic feet (BCFe),  or 11.5 BCFe above the level of production for 1997.
In 1998,  wellhead  prices  averaged  approximately  $1.96 per MCF compared with
$2.45 per MCF in 1997.  The effective  price  realized  (average  wellhead price
received for production including recognized hedging gains and losses) was $2.02
per MCF in 1998 compared with $2.25 per MCF in 1997.

ELECTRIC SERVICES
Revenues for the Transition Period are derived from service agreements with LIPA
for the  period  May 29,  1998  through  December  31,  1998.  Prior to the LIPA
Transaction,  LILCO provided fully integrated electric service to its customers.
Included  within  rates  charged  to  customers  was the  return on the  capital
investment in the generation and T&D assets, as well as recovery of the electric
business costs to operate the system.  Upon completion of the LIPA  Transaction,
the nature of the Company's  electric business has changed from that of owner of
an electric generation and T&D system, with significant capital investment, to a
new role as owner of the non-nuclear generation facilities and as manager of the
T&D system now owned by LIPA. In its new role, the Company's capital  investment
is significantly reduced and accordingly,  its revenues under the LIPA contracts
reflect that  reduction.  Revenues  after May 28, 1998 reflect the impact of the
LIPA agreements which contribute marginally to earnings.

Revenues  realized under the Management  Services  Agreement ("MSA") were $226.3
million for the period May 29, 1998 through  December 31, 1998.  These  revenues
were derived from the performance of the day-to-day operation and maintenance of
LIPA's T&D system,  management of construction  additions to the T&D system, and
the management of LIPA's  interest in the Nine Mile Point Nuclear Power Station,
Unit 2 ("NMP2").

Revenues under the Power Supply Agreement ("PSA"),  including incentives earned,
were $178.3  million for the period May 29, 1998  through  December 31, 1998 and
were  derived  from the sale of capacity  and energy to LIPA from the  Company's
generating  facilities  at  rates  approved  by the  Federal  Energy  Regulatory
Commission.

Revenues under the Energy Management  Agreement  ("EMA"),  including  incentives
earned,  were $3.7 million for the period May 29, 1998 through December 31, 1998
and resulted from the management of fuel supplies for LIPA to fuel the Company's
generating  facilities  and the  management of energy  purchases on a least-cost
basis to meet LIPA's needs.

See "Electric Services-LIPA  Agreements" for a more detailed description of each
of these agreements.

ELECTRIC DISTRIBUTION
Electric  revenues for the period April 1, 1998 through May 28, 1998  fluctuated
mainly as a result of system  growth,  and variations in weather and fuel costs.
However,  these  variations  had no impact on earnings due to the electric  rate
structure  in effect  at that  time,  which  included  a revenue  reconciliation
mechanism to eliminate the impact on earnings  caused by sales volumes that were
above or below  adjudicated  levels.  Base electric rates were  unchanged  since
December 1993.

OTHER REVENUES
Other  revenues for the Transition  Period  primarily  included  revenues of the
Company's  energy  management  subsidiary,  KEM,  and  the  Company's  marketing
subsidiary,  KES.  KEM  provides a variety of  services  in all facets of energy
management   services  to  customers  that  operate  commercial  and  industrial
facilities,  primarily within the New York City metropolitan area. Revenues have
been enhanced  through the continued  integration  of an  engineering  firm, and
heating,  ventilation and air conditioning  companies  purchased during the past
two years.  KES markets gas and  electricity,  and arranges  transportation  and
related  services,  largely  to retail  customers,  and has been  expanding  its
customer base.

OPERATING EXPENSES

GAS PURCHASED
Variations in gas costs have little  impact on operating  results as the current
gas rate  structure  of each of the  Company's  two gas  distribution  utilities
include a gas adjustment clause pursuant to which variations  between actual gas
costs and gas cost  recoveries  are  deferred and  subsequently  refunded to, or
collected from customers.

The cost of gas for the  Transition  Period was $318.7  million,  reflecting the
inclusion of gas costs for KSE subsequent to May 28, 1998,  offset,  in part, by
warmer than normal weather and the fact that the  Transition  Period covers only
nine months. The cost of gas for the twelve months ended March 31, 1998 and 1997
was $299.5 million and $308.4 million,  respectively,  and reflected warmer than
normal weather in both periods.  The cost of gas for the year ended December 31,
1996 was $322.6  million and reflected  colder than normal  weather  during that
time  period.  The  average  cost of gas has  decreased  in 1998 as  compared to
increases in 1997 and 1996.

FUEL AND PURCHASED POWER
Electric  fuel  expense  for the period  April 1, 1998  through May 28, 1998 was
$91.8  million.  In  accordance  with the EMA,  LIPA is  responsible  for paying
directly the costs of fuel and  purchased  power and, as a result,  the Company,
since May 29, 1998, no longer incurs any electric fuel expense.

Electric  fuel  expenses for the twelve months ended March 31, 1998 and 1997 and
December  31,  1996 were $658.3  million,  $646.4  million  and $640.6  million,
respectively.  Electric  fuel expense in all periods  reflected  growing  system
sales  quantities in each period and increased cost of fuel and purchased  power
each year. Variations in fuel and purchased power costs had little impact on

                                       39

<PAGE>

operating  results  during  these  periods as LILCO's  electric  rate  structure
included a mechanism  that  provided  for the  recovery or refund of actual fuel
costs which varied from the level collected in rates.

OPERATIONS AND MAINTENANCE EXPENSE
Operations and maintenance  expense for the Transition Period was $848.7 million
and included $63.8 million of costs  associated with the write-off of a customer
billing  system that was in  development.  Additionally,  in  December  1998 the
Company  completed  an  early  retirement  program  in which  approximately  600
employees  elected early  retirement and a related  expense of $64.6 million was
charged to  operations.  Moreover,  for the  Transition  Period,  operations and
maintenance expense included the costs associated with the management of the T&D
assets acquired by LIPA. Prior to the LIPA Transaction,  all T&D related capital
costs were  capitalized and charged to  depreciation  expense over the estimated
useful life of the related asset.  Since the LIPA  Transaction,  all T&D related
costs are  expensed  when  incurred  and  recovered  from LIPA  through  monthly
billings.

Operation and maintenance expense for the twelve months ended March 31, 1998 and
1997 and  December  31,  1996 was  $511.2  million,  $489.9  million  and $499.2
million,  respectively.   Reflected  in  all  periods  were  the  on-going  cost
containment  programs  implemented  by LILCO  which  resulted in  reductions  to
maintenance, distribution, and administrative and general expenses. However, for
the twelve months ended March 31, 1998,  operation and maintenance  expense also
reflected the recognition of higher  performance-based  employee  incentives and
certain other charges for employee benefits.

ELECTRIC REGULATORY AMORTIZATIONS
Prior to the LIPA  Transaction,  the RMC  included  within  electric  regulatory
amortizations  represented the difference  between LILCO's revenue  requirements
under  conventional  ratemaking  and the revenues  provided by its electric rate
structure.  The RMC  was  adjusted  for the  operation  of the  Fuel  Moderation
Component ("FMC")  mechanism and the difference  between LILCO's share of actual
operating costs at NMP2 and amounts provided for in electric rates.

In April 1998, the NYPSC authorized a revision,  effective  December 1, 1997, to
LILCO's method of recording its monthly RMC  amortization  from a  straight-line
levelized  basis over LILCO's rate year,  to a monthly  amortization  based upon
each month's  forecasted  revenue  requirement,  which more closely aligned such
amortization with LILCO's cost of service.  As a result of this change,  for the
period April 1, 1998 through May 28, 1998,  LILCO recorded $51.5 million more of
non-cash RMC credits to income (representing  accretion of the RMC balance),  or
$33.5  million  after-tax,  than it would have  under the  previous  method.  In
addition,  for the year ended March 31, 1998, LILCO recorded approximately $65.1
million more of non-cash RMC credits to income, or $42.5 million after-tax, than
it  would  have  under  the  previous  method.   In  connection  with  the  LIPA
Transaction,  which included the sale of electric related regulatory assets, the
RMC and all other electric regulatory  amortizations were discontinued.  Had the
RMC amortization  continued,  the total RMC amortization for the rate year ended
November  30,  1998,  would have been  equal to the amount  that would have been
provided for under the previous method.

                                       40

OTHER OPERATING EXPENSES
Depreciation and depletion  expense  reflected gas utility property and electric
generation  property  additions  for  all  periods  and  electric  T&D  property
additions for the periods prior to the LIPA  Transaction.  In addition,  for the
period May 29, 1998  through  December  31,  1998,  depreciation  and  depletion
expense reflected the gas production activities of the Company's gas exploration
and production subsidiary. This subsidiary recorded an impairment charge of $130
million in  December  1998 to reduce the value of its  proved  gas  reserves  in
accordance  with the  asset  ceiling  test  limitations  of the  Securities  and
Exchange  Commission  applicable to gas exploration  and development  operations
accounted  for under the full cost  method.  Offsetting  these  increases is the
effect  on  depreciation  expense  from  the  sale  of T&D  assets  and  nuclear
generation assets to LIPA.

Operating taxes  principally  included state and local taxes on utility revenues
and  property.  The  applicable  property  base  and tax  rates  generally  have
increased in all periods. However, significant property related assets were sold
to LIPA as part of the LIPA Transaction and, as a result,  subsequent to May 28,
1998,  property taxes on the sold assets are no longer  incurred by the Company.
For the twelve  months  ended March 31,  1998,  operating  taxes  reflected  the
expiration of a temporary  corporate surcharge on revenues previously imposed by
New York State.

Federal  income tax expense in all years  reflected  changes in pre-tax  income.
Pre-tax  income and the related  federal  income tax expense for the  Transition
Period  were  significantly  affected  by the  write-off  of a customer  billing
system, charges related to the early retirement program,  charges related to the
LIPA Transaction,  and the write-down of proved gas reserves. (See Note 3 to the
Consolidated Financial Statements, "Federal Income Tax.")

OTHER INCOME AND DEDUCTIONS

Other income and deductions for the Transition  Period  primarily  reflected the
non-recurring  charges  associated  with the LIPA  Transaction of $107.9 million
after-tax  and a $13  million  after-tax  charge for the  funding of the KeySpan
Foundation.  (See  Note  11 to the  Consolidated  Financial  Statements,  "Costs
Related to the LIPA  Transaction  and  Special  Charges.")  These  charges  were
offset,  in part,  by  earnings  of $49.2  million  from the  investment  of the
proceeds  from the LIPA  Transaction  and  earnings  from the  Company's  equity
investment in the Iroquois Gas Transmission System LP.

Other income and deductions for the twelve months ended March 31, 1998 primarily
included a charge of $31  million  with  respect to certain  benefits  earned by
former officers of LILCO offset by carrying  charges on certain of the Company's
electric regulatory assets resulting from electric ratemaking mechanisms.  Other
income and deductions  for the year ended December 31, 1996 consisted  primarily
of non-cash carrying charge income associated with regulatory assets.

INTEREST EXPENSE

As part of the LIPA  Transaction,  LIPA  has  assumed  substantially  all of the
outstanding debt of LILCO. The Company, in connection with the LIPA Transaction,
issued promissory notes to LIPA



                                       41
<PAGE>

for its continuing obligation to pay principal and interest on certain series of
debt that has been assumed by LIPA . (See Note 7 to the  Consolidated  Financial
Statements,  "Long Term Debt," for additional  information.) Interest expense of
$138.7 million for the Transition  Period  reflected the  significantly  reduced
level of outstanding debt resulting from the LIPA Transaction.

Interest  expense for the twelve months ended March 31, 1998 and 1997 was $404.5
million  and $435.2  million,  respectively.  Interest  expense in both  periods
reflected the lower outstanding debt level resulting from the retirement of $250
million of indebtness in February 1997. For the twelve months ended December 31,
1996, interest expense was $447.6 million reflecting  increased letter of credit
and commitment fees associated with a change in LILCO's credit rating in 1996.

LIQUIDITY AND CAPITAL RESOURCES

LIQUIDITY
At December 31, 1998,  the Company had cash and temporary  cash  investments  of
$942.8 million.  Effective January 1, 1999, the Company has available  unsecured
bank lines of credit of $300 million.

In addition,  THEC also has an  available  line of credit of $150 million with a
commercial  bank. At December 31, 1998, $133 million was outstanding  under this
facility.  Moreover,  in March 1998,  THEC issued $100 million of 8.625%  Senior
Subordinated Notes due 2008 that are subordinate to borrowings under THEC's line
of credit.  (See Note 7 to the  Consolidated  Financial  Statements,  "Long Term
Debt," for additional information.)

Prior to the LIPA  Transaction,  LILCO had available,  through  October 1, 1998,
$250 million under its  Revolving  Credit  Agreement,  of which $100 million was
borrowed for interim  financing.  In  addition,  LILCO had a bridge loan of $250
million to fund  certain  obligations  for  postretirement  benefits  other than
pensions.  A portion of the proceeds from the LIPA Transaction was used to repay
the  $350  million  of  borrowings  and  the  Revolving   Credit  Agreement  was
terminated.

During 1998, KSE had an available bank line of credit of $150 million, which was
available to finance  commercial  paper for Brooklyn Union.  This line of credit
applied  jointly to KSE and Brooklyn  Union.  Effective  December 31, 1998, this
line of credit  terminated.  There were no  outstanding  borrowings on this line
from May 29, 1998 through December 31, 1998.

As a result of the LIPA  Transaction,  the Company has a  significant  amount of
cash which it has used and intends to continue to use for,  among other  things,
the repurchase of shares of its common stock on the open market (as discussed in
greater detail below) and the expansion of its operations through one or more of
the  following  types of  transactions:  mergers with or  acquisitions  of other
utilities;  investments in new gas pipelines (and related assets such as storage
fields and  processing  plants)  and gas  exploration;  or the  purchase  and/or
construction of additional  electric power plants.  However, no assurance can be
given that any of the foregoing  types of  transactions  will occur or that such
transactions,  if completed, will be integrated with the Company's operations or
prove to be profitable.


                                    42
<PAGE>

In August 1998, the Company announced that the Board of Directors authorized the
purchase  of up to 10 percent of the  Company's  outstanding  common  stock,  or
approximately 15 million shares, through open market purchases.  In addition, on
October 30, 1998, the Company  announced that the Board of Directors  authorized
using up to an additional $500 million of cash for the purchase of common shares
in addition to the Board's  previous  authorization.  Purchases from the initial
authorization commenced on August 17, 1998. As of February 28, 1999, the Company
repurchased 15.9 million of its common shares for $472.5 million.

In December 1998, the Company  acquired,  through a subsidiary a 50% interest in
certain  midstream  natural gas assets  owned by Gulf Canada  Resources  Limited
("Gulf  Canada")  in western  Canada and formed a  partnership  with Gulf Canada
called Gulf Midstream Services Partnership ("GMS"). The Company paid Gulf Canada
$189  million and has  provided a three-year  $64.8  million loan on  commercial
terms  that,  at  Gulf  Canada's  option,  can be  repaid  or  exchanged  for an
additional  19.7%  interest  in GMS. In  connection  with this  investment,  the
Company has agreed to fund capital  expenditures of GMS for the next three years
up to a maximum of $36 million  including Gulf Canada's share, in exchange for a
proportionately increased share of GMS's cash flow.

In  December  1998,  the  Company,  through a  subsidiary,  paid $32  million to
increase its  investment in The Premier  Transco  Pipeline from 24.5% to 50%. In
addition,  during the quarter ended December 31, 1998 the Company  provided THEC
with a $150  million  line of credit.  As of December 31, 1998 THEC had borrowed
$80 million under this facility, which was used to fund a substantial portion of
the acquisition of three producing  offshore blocks in the Mustang Island region
of the Gulf of Mexico. Further, in December 1998, the Company made a $20 million
donation to establish the KeySpan  Foundation,  a  not-for-profit  philanthropic
foundation that will make donations to various charitable organizations.

In May 1998,  LILCO  reached a  settlement  with the  Internal  Revenue  Service
resolving  all audit  issues on federal  income tax returns  filed for the years
1981 through 1989. The settlement  required the payment of taxes and interest of
$9 million and $35 million,  respectively.  Adequate reserves for the payment of
such taxes and interest were provided in prior fiscal years.

The negative cash flow from operating  activities  for the Transition  Period is
due primarily to the fact that  significant  positive cash flows that arise from
revenues  generated  during a  heating  season  have not been  reflected  in the
Transition  Period.  Approximately 75% of total annual gas revenues are realized
during  the  heating  season  (November  1 to April 30) as a result of the large
proportion of heating  sales,  primarily  residential,  compared to total sales.
Moreover,  during the Transition  Period,  the Company funded an additional $250
million into Voluntary Employee's Beneficiary  Association trusts (see Note 4 to
the Consolidated Financial Statements,  "Postretirement Benefits").  Annual cash
flow from core utility  operations  has remained  strong and should  continue to
provide the Company with a substantial source of funds.

CAPITAL RESOURCES
Consolidated  capital expenditures for the Transition Period were $676.5 million
and are estimated to be $1.2 billion for the year ended December 31, 1999.

Capital expenditures related to the Gas Distribution segment were $128.4 million
during the Transition  Period and were primarily for the renewal and replacement
of mains and  services  and  expansion  of the gas  distribution  system on Long
Island. Gas Distribution capital expenditures are estimated to be $205.7 million
for 1999.

Capital  expenditures related to Electric Services were $54.1 million during the
Transition Period and were primarily for the renewal and replacement of electric
lines prior to May 28, 1998.  Capital  expenditures for 1999 are estimated to be
$684.4 million  including  approximately  $597 million  related to the Company's
January 1999 agreement  with  Consolidated  Edison Company of New York,  Inc. to
purchase  the 2,168  megawatt  Ravenswood  electric  generating  facility.  This
facility,  located in Long Island  City,  Queens,  includes  the 1,753  megawatt
Ravenswood  Generating  Station and the 415 megawatt  Ravenswood  Gas  Turbines.
Common plant  capital  expenditures  were $51.1  million  during the  Transition
Period and are estimated to be $28.4 million for 1999.

Capital  expenditures  related to Gas  Exploration  and  Production  were $182.7
million for the Transition  Period.  These capital  expenditures  reflected,  in
part, costs related to development of additional properties acquired in Southern
Louisiana and properties acquired in the Gulf of Mexico and costs related to the
continued  development of property  additions acquired in 1997 and 1996. Capital
expenditures  for 1999 are estimated to be $126.6 million,  which includes $81.9
million  related  to  the  Company's  share  of  costs  for   developmental  and
exploratory drilling and $44.7 million related to the Company's March 1999 joint
venture  agreement  with THEC to explore  for natural gas and oil over a term of
three years. Under the terms of this agreement,  the Company will acquire 45% of
THEC's  interest in certain  offshore  undeveloped  leases and will commit up to
$100 million per year to explore and develop these leases.

Capital expenditures related to equity investments in Energy Related Investments
during the Transition  Period were $231.8  million.  These capital  expenditures
included $42 million of equity  investments  primarily to increase the Company's
interest in The Premier Transco Pipeline.  The Company also has a 24.5% interest
in a gas distribution  system in Northern Ireland that is being  refurbished and
expanded.  Also included in capital  expenditures  for the Transition  Period is
$189 million of equity  investments  related to the  formation of a  partnership
with  Gulf  Canada,  discussed  previously.  Capital  expenditures  for 1999 are
estimated  to be  $84.7  million,  including  the  Company's  share  of  capital
expenditures  in GMS of $12  million  and costs  related to the first stage of a
joint  venture  with Duke  Energy  Corporation  and the  Williams  Companies  in
developing  the Cross Bay(sm)  pipeline,  which will transport gas from existing
interstate pipelines in New Jersey to New York City and Long Island.

Capital  expenditures  of $28.4  million for the  Transition  Period  related to
Energy  Related  Services  reflected  primarily  the  acquisition  of a heating,
ventilating and air-conditioning ("HVAC") company.

                                       44

<PAGE>

The HVAC company,  located in New Jersey, designs, builds, installs and services
HVAC systems for commercial and residential customers.  Through this acquisition
the Company will be able to expand its management and marketing  activities into
the  middle-market  segment.  The  balance is related  to  expansion  of ongoing
operations of subsidiaries within this segment.  Capital expenditures for fiscal
1999 are estimated to be $57.4 million relating to acquisitions and expansion of
ongoing operations.

The level of future capital expenditures is reviewed on an ongoing basis and can
be affected by timing, scope and changes in investment opportunities.

FINANCING

Proceeds  from common  stock  issued  through  employee  and  shareholder  stock
purchase  plans have  provided  equity of $10.2  million  during the  Transition
Period.

Prior to the LIPA  Transaction,  all of the outstanding  shares of the following
preferred stock series were called for redemption:  Series UU, Series GG, Series
QQ,  Series  CC,  Series B,  Series  D,  Series E,  Series F,  Series H,  Series
I-Convertible,  Series L and  Series  NN.  These  preferred  stock  series  were
redeemed at an aggregate cost of $363.2 million, including $25.2 million of call
premiums and accrued  dividends.  On May 28, 1998,  LIPA  reimbursed the Company
$339.1 million for the preferred stock series that were redeemed. (See Note 5 to
the  Consolidated   Financial   Statements,   "Capital  Stock,"  for  additional
information.)

Upon  consummation of the LIPA  Transaction,  all of the  outstanding  long-term
debt,  except  for the 1997  Series A  Electric  Facilities  Revenue  Bonds  due
December 1, 2027, was transferred to LIPA. The Company issued  promissory  notes
to LIPA for $1.048 billion,  which  represented an amount  equivalent to the sum
of: (i) the  principal  amount of 7.3% Series  Debentures  due July 15, 1999 and
8.2% Series  Debentures due March 15, 2023 outstanding at May 28, 1998, and (ii)
an allocation of certain of the Authority  Financing Notes. The promissory notes
contain identical terms to the debt referred to in items (i) and (ii) above.

On November 3, 1998, the Company extinguished a portion of its obligation of the
promissory notes relating to certain series of bonds that were called by LIPA on
December 1, 1998.  The  Company's  obligation  for these  bonds of $2.1  million
consisted  of the  principal  amount and the  interest  accrued and  unpaid.  An
additional  portion of the promissory notes was also extinguished on December 1,
1998 due to the  mandatory  sinking fund  redemption  of $1 million on a certain
series of Authority Financing Notes.

On  March  1,  1999,  LIPA  converted  all of  the  transferred  long-term  debt
outstanding at variable rates to fixed rates of 5.15% and 5.30% per annum. As of
March 1, 1999,  the  remaining  debt  instruments  that  include  variable  rate
features  had a carrying  value of $149.9  million.  If  interest  rates were to
change on this variable rate debt by 100 basis points,  interest expense, net of
tax,  would  change  by less than a  million  dollars.  The rates of each of the
Company's gas utilities reflect the recovery of



                                    45
<PAGE>

a fixed level of interest  expense and, in addition,  the LIPA  agreements  also
include  recovery  of a base  level  of  interest  expense.  (See  Note 7 to the
Consolidated  Financial Statements,  "Long Term Debt" for additional information
on debt obligations.)

In December 1998, the Company  purchased a portfolio of securities  representing
direct purchase obligations of the U.S. Government. These securities were placed
in trust,  irrevocably  dedicated  to the  repayment  of certain Gas  Facilities
Revenue  Bonds  ("GFRB"),   thereby  effecting  an  in-substance  defeasance  of
approximately  $8.9 million  including  interest.  The  in-substance  defeasance
represents $4 million of outstanding bonds of each of the 6.75% Series 1989A due
February 2024 and the 6.75% Series 1989B due February  2024. The Company has not
been  relieved  of its  obligation  to service  the debt and remains the primary
obligor.  As a  result,  the  liability  is not  considered  extinguished  under
Statement of Financial  Accounting  Standards ("SFAS") No. 125,  "Accounting for
Transfers and Servicing of Financial Assets and  Extinguishment of Liabilities."
(See Note 7 to the  Consolidated  Financial  Statements,  "Long  Term  Debt" for
additional information on debt obligations.)

The  Company  intends  to  use a  combination  of  existing  cash  balances  and
internally  generated cash from operations to the maximum extent  practicable to
satisfy  stock  dividends  and  on-going  enhancements  to its gas  distribution
system.  The  Company  expects to access the  financial  markets  during 1999 to
satisfy approximately $400 million of maturing debt obligations. With respect to
the acquisition of the Ravenswood facilities discussed  previously,  the Company
intends to use some form of project financing for approximately  $425 million of
the purchase price. To the extent  necessary,  the Company can issue  short-term
commercial paper to finance  seasonal  working capital  requirements and if need
be, the Company has the ability to issue  tax-exempt  bonds through the New York
State Energy Research and Development Authority.

DIVIDENDS

The Company is currently paying a dividend at an annual rate of $1.78 per common
share.  The  Company's  dividend  policy is  reviewed  annually  by the Board of
Directors.  The  amount and timing of all  dividend  payments  is subject to the
discretion of the Board of Directors  and will depend upon business  conditions,
results of operations, financial conditions and other factors.

Common stock  dividends are payable on February 1, May 1, August 1, and November
1. In addition,  the Company pays an annual  dividend at the rate of $1.9875 per
share on the 7.95%  Preferred  Stock  Series  AA.  Common  and  preferred  stock
dividend  payments  made by the  Company  after  June 17,  1998 were a return of
capital for Federal income tax purposes for 1998.

Pursuant  to the  NYPSC's  orders  dated  February  5, 1998 and  April 14,  1998
approving the KeySpan  Acquisition,  Brooklyn Union's and Brooklyn Union of Long
Island's  ability to pay  dividends to the parent  company is  conditioned  upon
maintenance of a utility capital  structure with debt not exceeding 55% and 58%,
respectively,  of  total  utility  capitalization.  In  addition,  the  level of
dividends  paid by both  utilities may not be increased from current levels if a
40 basis point penalty


                                       46
<PAGE>

is  incurred  under the  customer  service  performance  program.  At the end of
Brooklyn  Union's and Brooklyn  Union of Long Island's rate years,  the ratio of
debt to total utility capitalization was 44% and 50%, respectively.

GAS DISTRIBUTION - RATE MATTERS

By  orders  dated  February  5, 1998 and April  14,  1998 the NYPSC  approved  a
Stipulation Agreement  ("Stipulation") among Brooklyn Union, LILCO, the Staff of
the Department of Public  Service and six other parties that in effect  approved
the KeySpan  Acquisition  and  established gas rates for both Brooklyn Union and
Brooklyn Union of Long Island.  Under the Stipulation,  $1 billion of efficiency
savings,  excluding  gas costs,  attributable  to operating  synergies  that are
expected to be realized over the 10 year period following the  combination,  are
to be allocated to ratepayers net of transaction costs.

Under the  Stipulation,  effective May 29, 1998,  Brooklyn Union's base rates to
core customers  were reduced by $23.9 million  annually.  In addition,  Brooklyn
Union is now subject to an earnings sharing provision  pursuant to which it will
be required to credit core customers with 60% of any utility  earnings up to 100
basis points above  certain  threshold  return on equity levels over the term of
the rate plan (other than any earnings associated with discrete  incentives) and
50% of any utility  earnings in excess of 100 basis points above such  threshold
levels.  The threshold  levels are 13.75% for the rate year ended  September 30,
1998,  13.50% for the rate years 1999 through 2001, and 13.25% for the rate year
2002. A safety and  reliability  incentive  mechanism was implemented on May 29,
1998, with a maximum 12 basis point pre-tax return on equity penalty if Brooklyn
Union fails to achieve certain safety and reliability performance standards.

The Stipulation also required Brooklyn Union of Long Island to reduce base rates
to its customers by $12.2 million annually  effective February 5, 1998 and by an
additional $6.3 million annually effective May 29, 1998.  Brooklyn Union of Long
Island is subject  to an  earnings  sharing  provision  pursuant  to which it is
required to credit to firm  customers  60% of any  utility  earnings in any rate
year up to 100 basis  points  above a return on equity of 11.10%  and 50% of any
utility  earnings  in excess of a return on equity of  12.10%.  Both a  customer
service  and a safety  and  reliability  incentive  performance  mechanism  were
implemented  effective  December 1, 1997 with maximum  pre-tax  return on equity
penalties of 40 and 12 basis  points,  respectively,  if Brooklyn  Union of Long
Island fails to achieve certain performance standards in these areas.

As a result of the  Stipulation,  synergy  savings  have been  reflected in base
rates  before  they  actually  will be realized  by the  Company.  As part of an
overall  plan to realize the synergy  savings,  the Company  initiated  an early
retirement  program  in  December  1998 in  which  approximately  600  employees
participated.  The Company is committed to realizing the $1 billion of operating
synergy  savings over a 10-year period  through an on-going  combination of cost
reductions and increased  operating  efficiencies.  However, no assurance can be
given as to what savings may be obtained from these efforts.

ELECTRIC SERVICES - LIPA AGREEMENTS

The Company,  through  certain of its  subsidiaries,  provides  services to LIPA
under the following agreements:

MANAGEMENT SERVICES AGREEMENT ("MSA")

A Company subsidiary manages the day-to-day operations,  maintenance and capital
improvements of the T&D system.  LIPA will exercise control over the performance
of the T&D system through specific standards for performance and incentives.  In
exchange for providing the services,  the Company will earn a $10 million annual
management fee and will be operating under an eight-year contract which provides
certain  incentives and imposes certain  penalties  based upon its  performance.
Annual service  incentives or penalties  exist under the MSA if certain  targets
are  achieved  or not  achieved.  In  addition,  the  Company  can earn  certain
incentives  for  cost  reductions  associated  with the  day-to-day  operations,
maintenance  and capital  improvements  of LIPA's T&D system.  These  incentives
provide for the Company to (i) retain  100% of cost  reductions  on the first $5
million in reductions,  and (ii) retain 50% of additional  cost reductions up to
15% of the total cost budget,  thereafter all savings will accrue to LIPA.  With
respect to cost  overruns,  the  Company  will  absorb the first $15  million of
overruns,  with a sharing  of  overruns  above $15  million.  There are  certain
limitations on the amount of cost sharing of overruns.  To date, the Company has
performed its obligations  under the MSA within the agreed to budget  guidelines
and the Company is committed to providing  on-going  services to LIPA within the
established  cost  structure.  However,  no assurances can be given as to future
operating results under this agreement.

POWER SUPPLY AGREEMENT ("PSA")

A  Company  subsidiary  sells to LIPA all of the  capacity  and,  to the  extent
requested,  energy from the  Company's  existing  oil and  gas-fired  generating
plants. Sales of capacity and energy are made with rates approved by the Federal
Energy Regulatory  Commission ("FERC").  The rates may be modified in the future
in  accordance  with the terms of the PSA for (i) agreed  upon labor and expense
indices applied to the base year, (ii) a return of and on net capital  additions
required for the generating  facilities,  and (iii) reasonably incurred expenses
that are outside the control of the  Company.  Rates  charged to LIPA  include a
fixed and  variable  component.  The  variable  component is billed to LIPA on a
monthly basis and is dependent on the amount of megawatt hours dispatched.  LIPA
has no  obligation  to purchase  energy from the Company and is able to purchase
energy on a least-cost basis from all available sources consistent with existing
interconnection  limitations  of the T&D System.  The Company  must,  therefore,
operate its  generating  facilities in a manner such that the Company can remain
competitive with other producers of energy.  To date, the Company has dispatched
to LIPA and LIPA has  accepted  the level of energy  generated  at the agreed to
price per megawatt hour . However,  no  assurances  can be given as to the level
and price of energy to be  dispatched  to LIPA in the future.  The PSA  provides
incentives and penalties that can total $4 million  annually for the maintenance
of the output capability of the generating  facilities.  The PSA runs for a term
of fifteen years.

                                       48

<PAGE>


In addition,  three years after the LIPA  Transaction is consummated,  LIPA will
have the right for a one-year period to acquire all of the Company's  generating
assets  included in the PSA at the fair market value at the time of the exercise
of the right, which value will be determined by independent appraisers.

ENERGY MANAGEMENT AGREEMENT ("EMA")

The EMA provides for a Company  subsidiary  to procure and manage fuel  supplies
for LIPA to fuel the  generating  facilities  under  contract  to it and perform
off-system  capacity and energy  purchases on a least-cost  basis to meet LIPA's
needs.  In exchange for these  services the Company  earns an annual fee of $1.5
million. In addition, the Company will arrange for off-system sales on behalf of
LIPA of excess output from the  generating  facilities  and other power supplies
either owned or under  contract to LIPA.  LIPA is entitled to  two-thirds of the
profit  from  any  off-system  energy  sales.  In  addition,  the  EMA  provides
incentives  and  penalties  that can total $7 million  annually for  performance
related to fuel  purchases  and  off-system  power  purchases.  The EMA covers a
period of fifteen years for the procurement of fuel supplies and covers a period
of eight years for off-system management services.

ENVIRONMENTAL

The Company  will be required to complete  the  investigation  and  undertake an
appropriate  level of  remediation  at  manufactured  gas  plant  ("MGP")  sites
formerly  operated by  Brooklyn  Union (or its  predecessors)  and LILCO (or its
predecessors).  With  respect to the Brooklyn  Union MGP sites,  the Company has
recently completed a Focused  Feasibility Study ("FFS") for the Brooklyn Borough
Works Site in Coney Island in  accordance  with the terms of its  Administrative
Order on Consent  ("ACO") with the New York State  Department  of  Environmental
Conservation ("DEC"). The FFS identified remedial action alternatives consistent
with  potential  future  commercial  re-use of the  property in the future;  the
Company anticipates  finalizing and implementing its choice of a remedial action
alternative  in the near  future.  At the  Clifton  site in Staten  Island,  the
Company is in the early stage of its  investigation  pursuant  to its ACO.  With
respect to the  Citizens  site,  the Company is waiting for a response  from the
City of New York regarding a  cost-sharing  agreement for the  investigation  of
that site;  although there is no current legal  obligation to address this site,
the Company  anticipates that a site  investigation will likely be undertaken in
the future.  Although the Company has identified other former Brooklyn Union MGP
sites to governmental authorities,  based upon current information,  the Company
does not believe  that an  obligation  to  investigate  and/or  remediate  these
properties is likely.

With respect to six of the former LILCO MGP sites,  it is  anticipated  that two
ACO's with the New York DEC will be finalized  in the near  future.  These ACO's
will establish an obligation to investigate  and remediate these six properties.
After the execution of the ACO for these six sites, the Company anticipates that
it will  enter  into  further  negotiations  with  the DEC with  respect  to the
preliminary investigation of other former LILCO MGP sites not currently owned by
the Company.

                                       49

<PAGE>


Although it is likely that such a preliminary  investigation  will be undertaken
in the future,  it is not currently known whether there will be an obligation to
remediate any of these properties.

The Company estimates the minimum cost of its MGP-related  environmental cleanup
activities will be $130.3 million and has recorded a related  liability for such
amount.  Further,  as of December  31,  1998,  the Company  has  expended  $13.7
million.

The  Company is  awaiting  final  development  of state and  federal  regulatory
programs  with respect to NOX  reduction  requirements  for its  existing  power
plants.  The  Company's  compliance  strategy  may be  composed  of fuel  choice
decisions,  acquisition of pollution credits,  and/or  installation of pollution
control   equipment.   Although  the  Company  is  currently   considering   its
alternatives,  final decisions cannot be made until the regulatory  requirements
are  clarified.  Expenditures  to implement a final strategy are not expected to
begin until 2001.

Additional capital expenditures associated with the renewal of the surface water
discharge  permits for the  Company's  power  plants may be required by the DEC.
Until the final  permits  are  issued,  the Company  cannot  determine  what the
monitoring  obligations  will be,  the  results of any such  monitoring,  or the
impact that any required equipment upgrades would have on Company operations.

YEAR 2000 ISSUES

The Company has  evaluated  the extent to which  modifications  to its  computer
software, hardware and databases will be necessary to accommodate the year 2000.
The Company's  computer  applications  are generally  based on two digits and do
require  some  additional   programming  to  recognize  the  start  of  the  new
millennium.

System Readiness

A  corporate-wide  program  has been  established  to review  Company  software,
hardware, embedded systems and associated compliance plans. The program includes
both  information  technology  ("IT") and non-IT  systems.  Non-IT  systems  are
basically  vendor  supplied  embedded  systems  that are  critical  to the daily
operations of the Company.  These systems are generally in the areas of electric
production, distribution, transmission, gas distribution and communications. The
readiness of suppliers and vendor  systems is also under review.  The project is
under  the  direction  of the Year  2000  Program  Office,  chaired  by the Vice
President, Technology Operations and Corporate Y2K Officer.

The critical areas of operations are being addressed  through a business process
review  methodology.  Each of the Company's critical business processes is being
reviewed  to:  identify  and  inventory  sub-  components;  assess for year 2000
compliance;  establish  repair  plans  as  necessary;  and  test in a year  2000
environment.  The inventory  phase for both the IT systems and non-IT systems is
complete. The total assessment phase is 100% complete for the IT systems, and as
of December 31, 1998, over 90% complete for non-IT systems.

                                       50

<PAGE>


Hardware,  software  and embedded  systems are being tested and  certified to be
year 2000 ready.  As of December 31,  1998,  repair and testing was 70% complete
for the IT systems and 22% complete for the non-IT systems. Components needed to
support the critical  business  processes and  associated  business  contingency
plans are expected to be year 2000 ready by July 1, 1999.

Vendors and business partners needed to support the critical business  processes
are also being  reviewed for their year 2000  readiness.  At this time,  none of
these  vendors  have  indicated  to the  Company  that they  will be  materially
adversely affected by the year 2000 problem.

Risk Scenarios and Contingency Plans

The Company has  analyzed  each of the critical  business  processes to identify
possible year 2000 risks.  Each critical  business  process will be certified by
the responsible  corporate officer as being year 2000 ready.  However,  the most
reasonably  likely  worst case  scenarios  are also being  identified.  Business
operating  procedures are being reviewed to ensure that risks are minimized when
entering  the year 2000 and other high risk dates.  Contingency  plans are being
developed to address possible failure points in each critical  business process,
and are scheduled to be completed by July 1999.

While the Company must plan for the  following  possible  worst case  scenarios,
management believes that these events are improbable:

LOSS OF GAS PIPELINE DELIVERY
The  Company's  gas utility  subsidiaries  receive gas  delivery  from  multiple
national and international  pipelines and therefore the effects of a loss in any
one pipeline can be mitigated through the use of other pipelines.  Complete loss
of all the supply lines is not considered a reasonable  scenario.  Nevertheless,
the impact of the loss of any one  pipeline  is  dependent  on  temperature  and
vaporization rate. Should gas supply be decreased due to the loss of a pipeline,
each of the  Company's  gas  utility  subsidiaries  also  has a local  liquefied
natural gas  facility  under its direct  control that stores  sufficient  gas to
offset the temporary  loss of any one  pipeline.  The partial loss of gas supply
will not affect the Company's  ability to supply  electricity  since most of the
plants have the ability to operate on oil.

LOSS OF ELECTRIC GENERATION OR ELECTRIC TRANSMISSION AND DISTRIBUTION
Electric  utilities  are  physically  connected  on a  regional  basis to manage
electric load.  This is often  referred to as the regional  grid.  Presently the
Company is working,  on behalf of LIPA, with other regional utilities to develop
a coordinated  operating  plan.  Should there be an instability in the grid, the
Company has the ability to remove LIPA's facilities and operate independently.

Certain  electric system  components such as individual  generating  units,  T&D
control facilities, and the electric energy management system have the potential
to be affected by the year 2000 problem.  The Company has  inventoried  both its
and LIPA's  electric  system  components and developed a plan to certify mission
critical  processes as year 2000 ready.  As manager of the T&D  facilities,  the
Company is responsible for ensuring that these  facilities  operate properly and
that related systems


                                       51

<PAGE>


are year 2000 ready.  Under the terms of the various LIPA  contracts,  LIPA will
reimburse  the Company for certain  year 2000 costs  incurred by the Company for
these facilities.  Contingency plans are being developed, where appropriate, for
loss  of  critical  system  elements.   The  Company  presently  estimates  that
contingency plans regarding its electric  facilities should be completed by July
1999.

LOSS OF TELECOMMUNICATIONS
The Company has a substantial dependency on many  telecommunication  systems and
services  for both  internal  and  external  communication  providers.  External
communications  with the public  and the  ability of  customers  to contact  the
Company in cases of  emergency  response is  essential.  The Company  intends to
coordinate  its  emergency  response  efforts  with  the  offices  of  emergency
management  of the  various  local  governments  within its  service  territory.
Internally,  there  are a  number  of  critical  processes  in both  the gas and
electric  operating  areas  that  rely  on  external  communication   providers.
Contingency  plans will address methods for manually  monitoring these functions
and/or utilizing  alternative  communication  methods.  These  contingency plans
should be finalized by July 1999.

In  addition  to the above,  the  Company  is also  planning  for the  following
scenarios:   short  term  reduction  in  system  power  generating   capability;
limitation to fuel oil operations; reduction in quality of power output; loss of
automated meter reading; loss of ability to read customer meters,  prepare bills
and collect and process customer payments; and loss of the  purchasing/materials
management system.

The  Company  believes  that,  with   modifications  to  existing  software  and
conversions  to new  hardware  and  software,  the year 2000 issue will not pose
significant  operational  problems for its computer  systems.  However,  if such
modifications  and  conversions  are not made, or are not completed on time, and
contingency plans fail, the year 2000 issue could have a material adverse impact
on the  operations  of the  Company,  the extent of which  cannot  currently  be
determined.

Cost of Remediation

The Company expects to spend a total of approximately $32 million to address the
year 2000 issue. As of December 31, 1998, $15.8 million had been expended on the
project.  The largest  percentage  expended is  attributable  to the assessment,
repair and testing of  corporate  IT  supported  computer  software and in-house
written applications, which total $12.3 million. In 1999, the IT year 2000 costs
are  expected to be 8.3% of the IT budget.  The year 2000 issue has not directly
resulted in delaying any IT projects.  Presently,  the Company expects that cash
flow from  operations  and cash on-hand will be sufficient to fund the year 2000
project expenditures.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT RISK

The  Company and its  subsidiaries  are subject to various  risk  exposures  and
uncertainties  associated with their operations.  The primary risk exposures are
related  to  firm  gas  contracts,  financial  instruments,  various  regulatory
initiatives  of  the  NYPSC  and  FERC,  the  increasingly   competitive  energy
environment,  and to a lesser extent foreign  currency  fluctuations.  Set forth
below is a  description  of these  exposures  and an  explanation  as to how the
Company and its subsidiaries have managed and, to the extent possible, sought to
reduce these risks.

FIXED CHARGES UNDER FIRM CONTRACTS
The  Company's  gas utility  subsidiaries  have entered  into various  long-term
contracts  for gas  delivery,  storage  and supply  services in order to provide
sufficient  supply for their customers.  The contracts have remaining terms that
cover from one to fourteen years.  Certain of these contracts require payment of
monthly  charges  (demand  charges) in the aggregate  amount of $5.1 million per
month in all events regardless of the level of service available.  At this time,
the Company's exposure is minimal since these charges are currently recovered as
gas cost under the respective gas adjustment clauses contained in the tariffs of
the  Company's  gas  utility  subsidiaries.  The  Company  does not expect  rate
regulation  to change  in the  immediate  future  regarding  recovery  of demand
charges;  however,  the  Company  is unable to  predict  the  evolution  of rate
regulation. In addition,  Company subsidiaries have entered into agreements with
Enron  Corporation  and  Coral  Energy  Resources,  LP which  provide  for these
companies to engage in overall gas supply  management  arrangements  with and on
behalf of the Company.

DERIVATIVE FINANCIAL INSTRUMENTS
The  Company's  gas utility  subsidiaries,  marketing  and gas  exploration  and
production   subsidiaries  employ,  from  time  to  time,  derivative  financial
instruments,  such as natural gas and oil  futures,  options and swaps,  for the
purpose of hedging  exposure to commodity  price risk. At December 31, 1998, the
value at risk of the related  positions as measured by the maximum adverse price
movement in a single day was not material.

Whenever hedge positions are in effect,  the Company's  subsidiaries are exposed
to credit risk in the event of  nonperformance  by counter parties to derivative
contracts,  as well as nonperformance by the counter parties of the transactions
against which they are hedged. The Company believes that the credit risk related
to the futures,  options and swap instruments is no greater than that associated
with the  primary  commodity  contracts  which  they  hedge,  as the  instrument
contracts  are with major  investment  grade  financial  institutions,  and that
reduction of the exposure to price risk lowers the  Company's  overall  business
risk.  (See  Note  8 to  the  Consolidated  Financial  Statements,  "Contractual
Obligations, Financial Instruments and Contingencies.")

REGULATORY ISSUES AND THE COMPETITIVE ENVIRONMENT
The energy  industry  continues to undergo  fundamental  changes as  regulators,
elected officials and customers seek lower energy prices.  These changes,  which
may have a significant impact on the future financial  performance of utilities,
are being driven by a number of factors including a


                                       53

<PAGE>


regulatory  environment in which traditional  cost-based regulation is seen as a
barrier to lower energy prices.

Over the past few years,  the NYPSC has been  formulating a policy  framework to
guide the  transition  of New York  State's  gas  distribution  industry  in the
deregulated gas industry environment.  Since 1996, customers in the small-volume
market have been given the option to purchase  their gas  supplies  from sources
other than the Company's two gas utility  subsidiaries.  Large-volume  customers
have had this option for a number of years. In addition to transporting gas that
customers purchase from marketers,  the Company's  utilities have been providing
billing,  meter reading and other  services for  aggregate  rates that match the
distribution  charge  reflected  in otherwise  applicable  sales rates to supply
these customers.

In November 1998, the NYPSC issued a policy  statement  setting forth its vision
for  furthering  competition  in the natural gas  industry.  Under this  vision,
regulated natural gas utilities or local distribution  companies ("LDC's") would
plan to exit the  business of  purchasing  gas for and selling gas to  customers
(the merchant  function) over the next three to seven years.  LDC's would remain
the operators of the gas system (the distribution  function) and the provider of
last resort of natural gas  supplies  during that period and until  alternatives
are developed.  The NYPSC's goal is to encourage  more  competition at the local
level by separating the merchant function from the distribution function.

The NYPSC has acknowledged that each utility has operating  circumstances unique
to  its  service  territory  and  therefore   separation  of  the  merchant  and
distributions functions should be done on a utility-by-utility  basis. With this
in mind,  the NYPSC will  institute  individual  proceedings  for each regulated
natural gas utility so that the parties can determine the most  effective  means
of  achieving  the NYPSC's  goals.  In addition,  the NYPSC will also  institute
generic proceedings to examine reliability and other issues.

The  Company  conceptually   supports  the  vision  articulated  in  the  policy
statement.  However,  in the Company's  view,  any  transition to a new industry
structure must adequately  address a number of unresolved  issues to ensure that
separating  the merchant and  distribution  functions is in the best interest of
natural gas customers  and is equitable to LDC's.  Such issues  include:  system
reliability,  recovery of prudently  incurred  costs,  the obligation to provide
service to all firm  customers,  tax disparity among  suppliers,  administrative
overheads,  customer  acceptance  and the  obligation  to be  "supplier  of last
resort." Further, the Company will also pursue legislative changes where needed.
The Company  currently is not able to determine  what effect these  changes,  if
implemented, may have on its operations.

FOREIGN CURRENCY FLUCTUATIONS
The  Company  follows  the  principles  of  SFAS  No.  52,   "Foreign   Currency
Translation"  for recording its investments in foreign  affiliates.  At December
31, 1998, the foreign currency translation  adjustment was immaterial.  However,
due to the  Company's  recent  purchase of certain  Canadian  interests  and its
continued and possibly expanded activities internationally, foreign currency
translation  adjustments in the future could become  material,  the magnitude of
which  cannot  be  predicted  at  this  time.  (See  Note 1 to the  Consolidated
Financial Statements, "Summary of Significant Accounting Policies.")

ITEM 8.  FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA



FINANCIAL STATEMENT RESPONSIBILITY

The Consolidated  Financial  Statements of the Company and its subsidiaries were
prepared  by  management  in  conformity  with  generally  accepted   accounting
principles.

The  Company's  system of internal  controls  is designed to provide  reasonable
assurance  that assets are  safeguarded  and that  transactions  are executed in
accordance with management's  authorizations  and recorded to permit preparation
of financial statements that present fairly the financial position and operating
results of the Company.  The Company's  internal  auditors evaluate and test the
system of internal  controls.  The Company's Vice President and General  Auditor
reports  directly to the Audit  Committee  of the Board of  Directors,  which is
composed entirely of outside  directors.  The Audit Committee meets periodically
with management,  the Vice President and General Auditor and Arthur Andersen LLP
to review and discuss internal accounting  controls,  audit results,  accounting
principles and practices and financial reporting matters.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS


NOTE 1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

A.  REORGANIZATION

MarketSpan  Corporation d/b/a KeySpan Energy (the "Company") is the successor to
Long Island Lighting  Company  ("LILCO"),  as a result of a transaction with the
Long Island Power Authority ("LIPA") (the "LIPA  Transaction") and following the
acquisition (the "KeySpan  Acquisition") of KeySpan Energy Corporation  ("KSE").
The Company is a  "predominately  intrastate"  public  utility  holding  company
exempt from most of the provisions of the Public Utility  Holding Company Act of
1935,  as amended.  As a result of the  transaction  with LIPA,  LILCO  became a
wholly-owned  subsidiary of LIPA, a public authority and a political subdivision
of New York State.  KSE, a  wholly-owned  subsidiary  of the Company and also an
exempt utility  holding  company under the Public Utility Holding Company Act of
1935, as amended, is no longer a registrant under the Securities Act of 1933, as
amended, and the Securities Exchange Act of 1934, as amended.

On May 28, 1998, the Company completed two business  combinations as a result of
which  it  (i)  became  the  successor  operator  of  the  non-nuclear  electric
generating  facilities,  gas  distribution  operations and common plant formerly
owned by LILCO and entered  into  long-term  service  agreements  to operate the
electric  transmission  and  distribution  system  acquired  by  LIPA;  and (ii)
acquired KSE, the parent  company of The Brooklyn  Union Gas Company  ("Brooklyn
Union").  (See Note 2, "Sale of LILCO  Assets,  Acquisition  of  KeySpan  Energy
Corporation and Transfer of Assets and Liabilities to the Company.")

With  the  exception  of  a  small  portion  of  Queens  County,  the  Company's
subsidiaries are the only providers of gas distribution services in the New York
City  counties of Kings,  Richmond  and Queens and the Long  Island  counties of
Nassau and  Suffolk.  Brooklyn  Union  provides  gas  distribution  services  to
customers in the New York City boroughs of Brooklyn,  Queens and Staten  Island,
and KeySpan Gas East d/b/a  Brooklyn  Union of Long Island  ("Brooklyn  Union of
Long  Island"),  a Company  subsidiary,  provides gas  distribution  services to
customers  in the Long Island  counties  of Nassau and Suffolk and the  Rockaway
Peninsula of Queens County.

On September 10, 1998, the Company's  Board of Directors  authorized  filings to
permit the Company to conduct its business  under the name KeySpan  Energy.  The
Company will propose a formal name change for  shareholder  approval at its 1999
Annual Meeting of Shareholders. On October 20, 1998 the Company's symbol for its
common  stock and  preferred  stock Series AA listed on the New York and Pacific
Stock Exchanges was changed to "KSE."

B.  BASIS OF PRESENTATION

The Consolidated  Financial  Statements presented herein reflect the accounts of
the Company and its  subsidiaries.  Subsidiaries  comprising the Gas Exploration
and Production reportable segment

                                       62
<PAGE>




and the Energy Related Services reportable segment are fully consolidated in the
financial information presented.  All other subsidiary investments are accounted
for on the  equity  method as the  Company  does not have a  controlling  voting
interest or otherwise  have control over the  management of investee  companies.
All significant intercompany transactions have been eliminated.

Certain reclassifications were made to conform prior period financial statements
with the current period financial statement presentation.

For financial reporting purposes, LILCO is deemed the acquiring company pursuant
to a purchase accounting transaction,  in which KSE was acquired.  Consequently,
financial  results of the Company  prior to May 29, 1998 reflect  those of LILCO
only.  Since the  acquisition  of KSE was accounted  for as a purchase,  related
accounting adjustments, including goodwill, have been reflected in the financial
statements  herein.  Further,  the financial  statements  presented  reflect the
results of  operations  of LILCO from April 1, 1998  through May 28, 1998 and of
the fully  consolidated  entity from May 29, 1998 through  December 31, 1998. In
September 1998, the Company changed its fiscal year end to December 31. Further,
in April 1997,  LILCO  changed  its year end from  December 31 to March 31. As a
result,  the  financial  statements  presented  herein  include  the nine  month
transition  period  April 1, 1998  through  December  31, 1998 (the  "Transition
Period"),  the twelve  months ended March 31 1998,  the three months ended March
31, 1997 and the twelve months ended December 31, 1996.

The weighted average number of common shares outstanding used in the calculation
of earnings per share for the nine months ended  December 31, 1998 reflected the
issuance of common stock to consummate the KeySpan Acquisition and the reduction
associated with  repurchases of common stock subsequent to August 17, 1998. (See
Note 5,  "Capital  Stock.")  Further,  as of December 31, 1998,  the Company had
outstanding  921,066  unexercised  common  stock  options  held  by key  Company
employees.  These options have not been considered in measuring diluted earnings
per  share,  since  inclusion  of these  options in the  calculation  would have
resulted in an antidilutive effect for the Transition Period.

The preparation of financial  statements in conformity  with generally  accepted
accounting principles requires management to make estimates and assumptions that
affect  the  reported  amounts  of assets  and  liabilities  and  disclosure  of
contingent  assets and  liabilities at the date of the financial  statements and
the  reported  amounts of revenues  and expenses  during the  reporting  period.
Actual results could differ from those estimates.

C.  ACCOUNTING FOR THE EFFECTS OF RATE REGULATION

The  Company's  accounting  records for its two  regulated gas utilities and its
generation  subsidiary are  maintained in accordance  with the Uniform System of
Accounts  prescribed by the Public  Service  Commission of the State of New York
("NYPSC") and the Federal Energy Regulatory  Commission ("FERC"),  respectively.
The Company's  financial  statements reflect the ratemaking policies and actions
of these regulators in conformity with generally accepted accounting  principles
for rate- regulated enterprises.

The Company's two regulated gas utilities and its electric generation subsidiary
are subject to the  provisions  of Statement of Financial  Accounting  Standards
("SFAS") No. 71,  "Accounting  for the Effects of Certain Types of  Regulation."
This  statement  recognizes  the ability of  regulators,  through the ratemaking
process,   to  create  future  economic   benefits  and  obligations   affecting
rate-regulated companies. Accordingly, the Company records these future economic
benefits  and  obligations  as  regulatory  assets and  regulatory  liabilities,
respectively.

The  Company's  regulatory  assets of $279.5  million at  December  31, 1998 are
primarily comprised of regulatory tax assets, certain environmental  remediation
and investigation costs,  postretirement  benefits other than pensions and costs
associated with the KeySpan Acquisition.

Rate  regulation is undergoing  significant  change as regulators  and customers
seek lower  prices for  utility  service and greater  competition  among  energy
service  providers.  In the event  that  regulation  significantly  changes  the
opportunity for the Company to recover its costs in the future, all or a portion
of the Company's  regulated  operations  may no longer meet the criteria for the
application  of SFAS No. 71. In that event,  a write-down of all or a portion of
the Company's  existing  regulatory  assets and liabilities could result. If the
Company had been unable to  continue to apply the  provisions  of SFAS No. 71 at
December 31, 1998, the Company would have applied the provisions of SFAS No. 101
"Regulated  Enterprises - Accounting for the  Discontinuation  of Application of
FASB  Statement  No. 71." The Company  estimates  that the  write-off of its net
regulatory asset (regulatory assets less regulatory liabilities) could result in
a charge to net  income of $147.2  million  or $1.01 per share of common  stock,
which would be classified as an extraordinary item. In management's opinion, the
Company's  regulated  subsidiaries  will  be  subject  to  SFAS  No.  71 for the
foreseeable future.

As part of the LIPA  Transaction,  the Company has entered into various  service
agreements  with LIPA that  prescribe  the  conduct  of the  Company's  electric
operations.  These agreements allow the Company to recover its costs, subject to
negotiation,  incurred  to service  the  agreements  and  potentially  allow the
Company to earn a certain level of profit.  The Company's  electric  operations,
other  than the  generation  function  which is FERC  regulated,  are no  longer
subject to NYPSC rate  regulation  and as a result the Company no longer applies
SFAS No. 71 to its electric operations. As a result of the LIPA Transaction, all
regulatory assets and liabilities outstanding as of May 28, 1998 associated with
the  Company's  electric  operations  have been either sold or  written-off  and
therefore,  are no longer recorded in the accounts of the Company.  In addition,
certain issues relating to prior

                                       64
<PAGE>




electric  operations,  such as nuclear plant  decommissioning  and nuclear plant
insurance  are no longer  applicable to the Company since these assets were sold
to LIPA.  The net  regulatory  assets that were sold to LIPA as part of the LIPA
Transaction  amounted to $6.3  billion.  See Note 13,  "Disaggregated  Condensed
Balance Sheet (Unaudited)" for additional information.

D.  REVENUES

Utility gas  customers  are billed  monthly  and  bi-monthly  on a cycle  basis.
Revenues  include  unbilled  amounts  related  to the  estimated  gas usage that
occurred from the most recent meter reading to the end of each month.

The cost of gas is recovered as incurred when billed to firm  customers  through
the operation of the gas adjustment  clause ("GAC") included in utility tariffs.
The GAC provision requires an annual reconciliation of recoverable gas costs and
GAC revenues. Any difference is deferred pending recovery from or refund to firm
customers during a subsequent  twelve-month  period.  Further, net revenues from
tariff  gas  balancing   services,   off-system  sales  and  certain   on-system
interruptible  sales are refunded to firm customers  subject to certain  sharing
provisions.

The gas utility tariffs contain a weather normalization  adjustment that largely
offsets  shortfalls or excesses of firm net revenues  (revenues  less gas costs)
during a heating season due to variations from normal weather.

Electric revenues since the LIPA Transaction are primarily derived from billings
to LIPA for management of LIPA's  transmission and distribution  ("T&D") system,
electric  generation,  and procurement of fuel. The agreements with LIPA include
provisions  for  the  Company,  to earn in the  aggregate,  approximately  $11.5
million per year (plus up to an  additional  $5 million per year if certain cost
savings  are  achieved)  in  annual  management  service  fees from LIPA for the
management of the LIPA T&D system and the  management of all aspects of fuel and
power supply.  Costs in excess of budgeted  levels are assumed by the Company up
to $15 million,  while cost  reductions  in excess of $5 million  from  budgeted
levels are shared with LIPA.  These  agreements  also contain  certain  non-cost
incentive  and  penalty   provisions  which  could  impact  earnings.   Billings
associated with generation capacity are based on pre-determined levels of supply
to be dispatched to LIPA on a yearly basis.  Rates charged to LIPA include fixed
and variable  components.  The variable component is billed to LIPA on a monthly
basis and is dependent on the amount of megawatt hours dispatched.  In addition,
billings related to transmission,  distribution and delivery services are based,
in part, on negotiated budgeted levels.

Prior  to the  LIPA  Transaction,  electric  revenues  were  comprised  of cycle
billings  rendered to residential,  commercial and industrial  customers and the
accrual of electric  revenues for services  rendered to customers  not billed at
month-end.   In  addition,   LILCO's  rate  structure  provided  for  a  revenue
reconciliation  mechanism  which  eliminated  the impact on earnings of electric
sales that were above or below the levels reflected in rates. Moreover,  LILCO's
electric tariff  included a fuel cost  adjustment  ("FCA") clause which provided
for the disposition of the difference between actual



                                       65
<PAGE>




fuel costs and the fuel costs  allowed in base tariff  rates (base fuel  costs).
LILCO deferred  these  differences to future periods for recovery from or refund
to customers,  except for base electric fuel costs in excess of actual  electric
fuel costs, which were credited to the Rate Moderation Component as incurred.

E.  UTILITY PROPERTY - DEPRECIATION AND MAINTENANCE

Utility gas property is stated at original cost of construction,  which includes
allocations  of  overheads  and taxes and an  allowance  for funds  used  during
construction.  Mass properties  associated with gas operations,  such as meters,
are accounted for on an average unit cost basis by year of  installation.  Prior
to the LIPA Transaction,  electric T&D mass properties,  such as poles and wire,
were  accounted  for on an average unit cost basis by year of  installation.  As
part of the LIPA Transaction, all T&D assets were sold to LIPA, and as a result,
all costs  associated with the  maintenance of the T&D system  subsequent to May
28, 1998 are expensed and charged to LIPA.

Depreciation  is  provided on a  straight-line  basis in amounts  equivalent  to
composite rates on average depreciable  property.  The cost of property retired,
plus the cost of removal less salvage,  is charged to accumulated  depreciation.
The cost of repair and minor  replacement  and renewal of property is charged to
maintenance expense. The composite rates on average depreciable property were as
follows:

            Period                  Electric          Gas
            ------                  --------          ---
      9 Months Ended 12/31/98       2.40%             1.75%
      12 Months Ended 3/31/98       3.07%             2.04%
      3 Months Ended 3/31/97         .78%              .51%
      12 Months Ended 12/31/96      3.00%             2.00%


F.  GAS EXPLORATION AND PRODUCTION PROPERTY- DEPLETION AND DEPRECIATION

The full cost method of  accounting is used for  investments  in natural gas and
oil properties.  Under this method,  all costs of  acquisition,  exploration and
development  of natural gas and oil reserves are  capitalized  into a "full cost
pool" as  incurred,  and  properties  in the pool are  depleted  and  charged to
operations  using the  unit-of-production  method  based on the ratio of current
production to total proved natural gas and oil reserves. To the extent that such
capitalized costs (net of accumulated depreciation,  depletion and amortization)
less  deferred  taxes exceed the present  value  (using a 10% discount  rate) of
estimated future net cash flows from proved natural gas and oil reserves and the
lower of cost or fair  value of  unproved  properties,  such  excess  costs  are
charged to operations.  If a write-down is required, it would result in a charge
to  earnings  but  would  not  have an  impact  on  cash  flows  from  operating
activities.  Once incurred,  such impairment of gas properties is not reversible
at a later date even if gas prices  increase.  At December 31, 1998, The Houston
Exploration  Company  ("THEC"),  the Company's 64% owned gas and oil exploration
and production subsidiary,  recorded a $130 million write-down to its investment
in its proved gas reserves, which


                                       66
<PAGE>




is reflected  in the  accompanying  financial  statements.  As  permitted  under
generally accepted accounting principles,  THEC utilized February 1999 prices to
measure the write-down. If THEC had utilized December 1998 prices to measure the
write-down, the write-down would have been $66.6 million less.

Provisions for depreciation of all other non-utility  property are computed on a
straight line basis over useful lives of three to ten years.

G.  DERIVATIVE FINANCIAL INSTRUMENTS

The Company's  utility,  marketing and gas and oil  exploration  and  production
subsidiaries  employ,  from time to time,  derivative  financial  instruments to
hedge  exposure in cash flows due to  fluctuations  in the price of natural gas.
Utility hedging activities also involve use of derivatives  related to fuel oil,
which in certain markets  strongly  influence the selling price for natural gas.
The  Company's  hedging  strategies  meet  the  criteria  for  hedge  accounting
treatment under SFAS No. 80,  "Accounting for Futures  Contracts."  Accordingly,
gains and  losses on these  instruments  are  recognized  concurrently  with the
recognition of the related physical transactions.

The subsidiaries regularly assess the relationship between natural gas commodity
prices in "cash" and futures  markets.  The correlation  between prices in these
markets  has been  within a range  generally  deemed  to be  acceptable.  If the
correlation were not to remain in an acceptable  range,  the subsidiaries  would
account for financial instrument positions as trading activities.

H.  EQUITY INVESTMENTS

Certain  subsidiaries  own as  their  principal  assets  investments,  including
goodwill,  representing  ownership  interests  of 50% or less in  energy-related
businesses that are accounted for under the equity method. Goodwill, at December
31,  1998,  was $52.2  million for certain  investments  in Canada and  Northern
Ireland. The amortization period for the goodwill is over 15 and 40 years.

I.  FEDERAL INCOME TAX

In accordance with SFAS No. 109, "Accounting for Income Taxes" and NYPSC policy,
certain of the Company's regulated  subsidiaries recorded a regulatory asset for
the net cumulative  effect of having to provide deferred federal income taxes on
all  differences  between  tax and book bases of assets and  liabilities  at the
current  tax  rate  which  have  not yet been  included  in rates to  customers.
Investment  tax  credits,  which were  available  prior to the Tax Reform Act of
1986,  were  deferred in operating  expense and are  amortized as a reduction of
federal  income tax in other  income  over the  estimated  lives of the  related
property.


                                       67
<PAGE>

J.  SUBSIDIARY COMMON STOCK ISSUANCES TO THIRD PARTIES

The Company  follows an accounting  policy of income  statement  recognition for
parent company gains or losses from issuances of common stock by subsidiaries.

K.  Foreign Currency Translation

The  Company  follows  the  principles  of  SFAS  No.  52,   "Foreign   Currency
Translation,"  for recording its investments in foreign  affiliates.  Under this
statement,  all  elements of  financial  statements  are  translated  by using a
current exchange rate.  Translation  adjustments result from changes in exchange
rates from one reporting  period to another.  At December 31, 1998,  the foreign
currency  translation  adjustment  was  included  in  a  separate  component  of
shareholders' equity.

L.  GOODWILL

At December 31, 1998, the Company has recorded  goodwill in the amount of $201.9
million,  representing the excess of acquisition cost over the fair value of net
assets acquired related to its purchases of certain  consolidated  subsidiaries.
Goodwill is  amortized  over 20 to 40 years.  The Company  recorded  goodwill of
approximately  $177.4  million net of accumulated  amortization  of $2.5 million
relating to the KeySpan  Acquisition and approximately  $24.5 million related to
the acquisition of a heating,  ventilating, and air-conditioning company and the
acquisition of an engineering firm.

M.  RECENT ACCOUNTING PRONOUNCEMENTS

COMPREHENSIVE INCOME
The Company  has  adopted  SFAS No. 130  "Comprehensive  Income."  Comprehensive
income is the change in the equity of a company,  not  including  those  changes
that result from  shareholder  transactions.  All  components  of  comprehensive
income  are  required  to be  reported  in a new  financial  statement  that  is
displayed with equal prominence as existing financial statements.

SEGMENT DISCLOSURES
At December  31, 1998,  the Company  adopted  SFAS No. 131,  "Disclosures  about
Segments of an Enterprise  and Related  Information."  SFAS No. 131  establishes
standards for additional  disclosure  about  operating  segments for interim and
annual  financial   statements.   More   specifically,   it  requires  financial
information to be disclosed for segments whose operating results are reviewed by
the chief operating decision-maker for decisions on resource allocation. It also
requires related  disclosures about products and services,  geographic areas and
major customers.  The Company's segments are based on how management  internally
analyzes the business and allocates resources. (See Note 10, "Business Segments"
for additional information.)

<PAGE>




PENSION AND OTHER POSTRETIREMENT BENEFIT DISCLOSURES
At December 31, 1998, the Company  adopted SFAS No 132,  "Employers'  Disclosure
about  Pensions  and Other  Postretirement  Benefits."  This  statement  revises
employers' disclosure about pensions and other postretirement  benefit plans. It
does not change the  measurement or  recognition  of those plans.  The statement
standardizes the disclosure  requirements for pensions and other  postretirement
benefits,  requires additional information on changes in the benefit obligations
and fair values of plan  assets that will  facilitate  financial  analysis,  and
eliminates certain disclosures that are no longer considered useful.

DERIVATIVE INSTRUMENTS
In June 1998, the Financial  Accounting Standards Board ("FASB") issued SFAS No.
133,  "Accounting  for  Derivative  Instruments  and Hedging  Activities."  This
Statement   establishes   accounting  and  reporting  standards  for  derivative
instruments and for hedging activities. It requires that an entity recognize all
derivatives  as either  assets or  liabilities  in the  statement  of  financial
position and measure  those  instruments  at fair value.  The Company will adopt
SFAS No. 133 in the first  quarter of fiscal  year 2000.  The  Company  does not
expect any  material  earnings  effect  from  adoption of this  statement  as it
presently utilizes derivatives for hedging activities.

NOTE 2. SALE OF LILCO ASSETS,  ACQUISITION  OF KEYSPAN  ENERGY  CORPORATION  AND
TRANSFER OF ASSETS AND LIABILITIES TO THE COMPANY

On May 28, 1998, pursuant to the Agreement and Plan of Merger,  dated as of June
26, 1997 as amended, by and among the Company, LILCO, LIPA, and LIPA Acquisition
Corp.  (the "Merger  Agreement"),  LIPA acquired all of the  outstanding  common
stock of LILCO for $2.4975 billion in cash and thereafter directly or indirectly
assumed certain  liabilities  including  approximately  $3.4 billion in debt. In
addition,  LIPA  reimbursed  LILCO $339.1  million  related to certain series of
preferred stock which were redeemed by LILCO prior to May 28, 1998.  Immediately
prior to such acquisition,  all of LILCO's assets employed in the conduct of its
gas distribution business and its non-nuclear electric generation business,  and
all common assets used by LILCO in the operation and  management of its electric
T&D business and its gas distribution  business and/or its non-nuclear  electric
generation  business  (the  "Transferred  Assets")  were sold to the Company and
transferred  to  wholly-owned  subsidiaries  of the  Company  at  the  Company's
direction.

The consideration  for the Transferred  Assets consisted of (i) 3,440,625 shares
of the common stock of the Company (ii) 553,000 shares of the Series B preferred
stock of the Company,  (iii) 197,000  shares of the Series C preferred  stock of
the Company,  and (iv) the  assumption by the Company of certain  liabilities of
LILCO.  In connection  with the transfer and prior to the  effectiveness  of the
LIPA Transaction, LILCO sold Series B and C preferred stock for $75 million in a
private placement.


                                       69
<PAGE>




Moreover,  all of LILCO's outstanding  long-term debt as of May 28, 1998, except
for its 1997 Series A Electric  Facilities  Revenue  Bonds due  December 1, 2027
which were assigned to the Company,  was assumed by LIPA. In accordance with the
LIPA  Transaction,  the Company  issued  promissory  notes to LIPA  amounting to
$1.048  billion  which  represented  an amount  equivalent to the sum of (i) the
principal  amount of 7.3%  Series  Debentures  due July 15, 1999 and 8.2% Series
Debentures  due March  15,  2023  outstanding  as of May 28,  1998,  and (ii) an
allocation of certain of the Authority  Financing  Notes.  The promissory  notes
contain  identical  terms to the debt  referred  to in items (i) and (ii) above.
(See Note 7, "Long-Term Debt" for additional information.)

On May 28, 1998, immediately subsequent to the LIPA Transaction,  KSE was merged
with and into a subsidiary of the Company,  pursuant to an Agreement and Plan of
Exchange and Merger,  dated as of December 29, 1996,  between LILCO and Brooklyn
Union.  This agreement was amended and/or  restated as of February 7, 1997, June
26, 1997, and September 29, 1997, to reflect certain  technical  changes and the
assignment  by  Brooklyn  Union of all of its rights and  obligations  under the
agreement  to KSE.  On  September  29,  1997,  KSE became the parent  company of
Brooklyn Union when Brooklyn Union reorganized into a holding company structure.

As a result of these  transactions,  holders of KSE common  stock  received  one
share of the Company's common stock, par value $.01 per share, for each share of
KSE they owned and holders of LILCO  common stock  received  0.880 of a share of
the Company's common stock for each share of LILCO they owned.  Upon the closing
of these  transactions,  former  holders  of KSE and  LILCO  owned  32% and 68%,
respectively, of the Company's common stock.

The  purchase  price  of  $1.223  billion  for the  acquisition  of KSE has been
allocated to assets acquired and liabilities  assumed based upon their estimated
fair values. The fair value of the utility assets acquired is represented by its
book value which  approximates the value recognized by the NYPSC in establishing
rates  for  regulated  utility  services.  The  estimated  fair  value  of KSE's
non-utility  assets  approximated  their carrying  values.  At May 28, 1998, the
Company  recorded  goodwill  in  the  amount  of  $179.9  million,  representing
primarily  the  excess of the  acquisition  cost over the fair  value of the net
assets acquired; the goodwill is being amortized over 40 years.

The following is the comparative unaudited proforma combined condensed financial
information  for the nine months ended  December 31, 1998 and the twelve  months
ended March 31,  1998.  The  proforma  disclosures  are  intended to reflect the
results of operations as if the KeySpan Acquisition was consummated on the first
day of each of the reporting  periods below. The effects of the LIPA Transaction
have been reflected for the period May 29, 1998 through December 31, 1998. These
disclosures may not be indicative of future results.

</TABLE>


The  decrease in revenues  for the  Transition  Period as compared to the twelve
months ended March 31, 1998 is due primarily to the LIPA Transaction consummated
on May 28, 1998.  Electric  revenues for the Transition  Period are derived from
service  agreements  with LIPA for the period May 29, 1998 through  December 31,
1998.  For the period  April 1, 1998  through May 28,  1998,  and for the twelve
months  ended March 31,  1998,  revenues  reflected  fully  integrated  electric
service to customers.  Included within rates charged to customers,  prior to the
LIPA Transaction, was the return on the capital investment in the generation and
T&D assets  required to operate  the system as well as recovery of the  electric
business costs to operate the system.  Upon completion of the LIPA  Transaction,
the nature of the Company's  electric business has changed from that of an owner
of an electric  generation and T&D system,  with significant capital investment,
to a new role as owner of the non-nuclear  generation  facilities and as manager
of the T&D  system now owned by LIPA.  In its new role,  the  Company's  capital
investment is significantly reduced and accordingly, its revenues under the LIPA
contracts reflect that reduction. Revenues after May 28, 1998 reflect the impact
of the LIPA agreements which contribute marginally to earnings.

Gas distribution revenues for the Transition Period do not include revenues from
heating season operations  (January through March) when the Company realizes the
major  portion  of its  gas  revenues.  Gas  distribution  revenues  during  the
Transition  Period were also impacted by rate reductions which were reflected at
the time of the KeySpan  Acquisition.  Brooklyn  Union reduced rates to its core
customers by $23.9 million annually effective May 29, 1998 and Brooklyn Union of
Long  Island  reduced  its rates to core  customers  by $12.2  million  annually
effective  February 5, 1998 and by an additional $6.3 million annually effective
May 29, 1998.

Net income for the Transition  Period also reflected  substantial  non-recurring
charges  associated  with the LIPA  Transaction  of  $107.9  million  after-tax,
special  charges related to the KeySpan  Acquisition of $83.5 million  after-tax
and a $13  million  after-tax  donation  made by the  Company to  establish  the
KeySpan  Foundation.  See Note 11, "Costs  Related to the LIPA  Transaction  and
Special Charges" for additional details.

     tax  basis  and (b)  certain  credits  for  financial  reporting  purposes,

     benefits,  partially offset by income taxes associated with the sale of the
     Transferred Assets to the Company by LIPA which taxes are to be paid by the
     Company.

The Company currently has federal income tax loss carryforwards of approximately
$149.1  million  that  expire in twenty  years or in 2017,  representing  losses
incurred by the Company for the nine months ended December 31, 1998.

In 1990 and 1992,  LILCO  received an Internal  Revenue  Service  Agents' Report
disallowing  certain  deductions  and  credits  claimed by LILCO on its  federal
income tax returns for the years 1981 through  1989. A settlement  resolving all
audit issues was reached  between LILCO and the Internal  Revenue Service in May
1998.  The  settlement  required the payment of taxes and interest of $9 million
and $35  million,  respectively,  which the Company  made in May 1998.  Adequate
reserves to cover such taxes and interest were previously provided.

NOTE 4.  POSTRETIREMENT BENEFITS

PENSION PLANS: The following information represents consolidated results for the
Company and its subsidiaries  (Brooklyn Union, Brooklyn Union of Long Island and
the former LILCO),  whose  noncontributory  defined  benefit pension plans cover
substantially  all  employees.  Benefits  are  based  on years  of  service  and
compensation. Funding for pensions is in accordance with requirements of federal
law and regulations. Prior to the KeySpan Acquisition, pension benefits had been
managed separately by the Company's regulated subsidiaries,  which were the only
subsidiaries  with  defined  benefit  plans.  The  Company is in the  process of
examining the  feasibility of  integrating  these plans into a more unified form
within the holding company structure.

The amounts  presented are consolidated for periods  subsequent to May 28, 1998.
Prior to that date the  amounts  pertain  solely to the plan of LILCO.  Brooklyn
Union of Long  Island is  subject to certain  deferral  accounting  requirements
mandated by the NYPSC for pension costs and other postretirement  benefit costs.
Amounts included herein also include accruals  pertaining to supplemental  plans
of the Company for obligations arising subsequent to May 28, 1998.

The calculation of net periodic pension cost follows:

INFORMATION ON THE LILCO SUPPLEMENTAL PLAN
The  Supplemental  Plan in effect  prior to May 28, 1998  provided  supplemental
death and  retirement  benefits for officers  and other key  executives  without
contribution from such employees. The Supplemental Plan was a non-qualified plan
under the Internal Revenue Code of 1986, as amended (the "Code").  The provision
for plan benefits totaled $0.7 million for the three months ended March 31, 1997
and $2.7 million for the year ended  December 31,  1996.  For the twelve  months
ended March 31, 1998,  a charge of $31 million was recorded  relating to certain
benefits earned by former officers of LILCO relating to the termination of their
annuity  benefits  earned  through the  supplemental  retirement  plan and other
executive  retirement  benefits.  This charge, which was borne by LILCO, and not
recovered from ratepayers,  resulted from provisions in the employment contracts
of LILCO officers.

OTHER  POSTRETIREMENT  BENEFITS - RETIREE  HEALTH CARE AND LIFE  INSURANCE:  The
following  information  represents  consolidated results for the Company and its
subsidiaries  (Brooklyn  Union,  Brooklyn  Union of Long  Island  and the former
LILCO) who sponsor noncontributory defined benefit plans under which is provided
certain  health care and life  insurance  benefits  for retired  employees.  The
Company has been funding a portion of future  benefits  over  employees'  active
service  lives  through  Voluntary  Employee  Beneficiary  Association  ("VEBA")
trusts. Contributions to VEBA trusts are tax deductible,  subject to limitations
contained in the Code.  Prior to the KeySpan  Acquisition  other  postretirement
benefits had been managed  separately by the Company's  regulated  subsidiaries,
which were the only  subsidiaries  with defined benefit plans. The Company is in
the process of examining the feasibility of integrating  these plans into a more
unified form within the holding company structure.

The amounts  presented herein are  consolidated  for periods  subsequent May 28,
1998. Prior to that date the amounts pertain solely to the plan of LILCO.

The measurement of plan  liabilities  also assumes a health care cost trend rate
of 6% annually.  A 1% increase in the health care cost trend rate would have the
effect of increasing the  accumulated  postretirement  benefit  obligation as of
December 31, 1998 by $103.8 million and the net periodic  health care expense by
$7.9  million.  A 1%  decrease in the health care cost trend rate would have the
effect of decreasing the  accumulated  postretirement  benefit  obligation as of
December 31, 1998 by $82.3  million and the net periodic  health care expense by
$6.2 million.

In 1993,  LILCO adopted the provisions of SFAS No. 106,  "Employer's  Accounting
for Post- Employment  Benefits Other Than Pensions," and recorded an accumulated
postretirement benefit obligation and a corresponding regulatory asset of $376.0
million.  LIPA will  reimburse the Company for costs  related to  postretirement
benefits of the electric  business unit  employees;  therefore,  the Company has
reclassified  the regulatory asset for  postretirement  benefits to a receivable
from LIPA.

In 1994, LILCO established VEBA trusts for union and non-union employees for the
funding of costs collected in rates for postretirement benefits. The trusts were
funded with contributions of $21.0 million for the twelve months ended March 31,
1998,  $5.0 million for the three months ended March 31, 1997 and $18.0  million
for the year ended December 31, 1996. In May 1998, an additional  $250.0 million
was funded into the trusts.

stock and called for redemption on May 19, 1998 all of the outstanding shares of
preferred  stock  Series B,  Series  D,  Series E,  Series F,  Series H,  Series
I-Convertible,  Series L and  Series  NN.  These  preferred  stock  series  were
redeemed for $117.5 million,  including accrued and unpaid dividends,  plus $4.5
million of call premiums.  In addition,  pursuant to the LIPA  Transaction  each
share of  non-redeemable  preferred  stock Series CC,  Series GG,  Series QQ and
Series UU was canceled and  converted to cash in the amount of the present value
plus  accrued  and unpaid  dividends.  The  non-redeemable  preferred  stock was
converted for $223.2 million,  including accrued and unpaid dividends,  plus $18
million of call premiums.  On May 28, 1998,  LIPA  reimbursed the Company $339.1
million for the preferred stock series that were redeemed.

Dividends on preferred stock are paid in preference to dividends on common stock
or any other stock ranking junior to preferred stock.

NOTE 6.  NONQUALIFIED STOCK OPTIONS

At December 31, 1998, the Company had  stock-based  compensation  plans that are
described  below.  Moreover,  under a separate plan,  THEC has issued  2,124,438
stock options to key THEC employees.  The Company and THEC apply APB Opinion 25,
"Accounting  for Stock  Issued to  Employees,"  and related  Interpretations  in
accounting  for  their  plans.  Accordingly,   no  compensation  cost  has  been
recognized  for these fixed stock  option  plans in the  Consolidated  Financial
Statements  since the exercise  prices and market values were equal on the grant
dates. Had  compensation  cost for these plans been determined based on the fair
value at the grant dates for awards  under the plans  consistent  with SFAS 123,
"Accounting for Stock-Based  Compensation,"  the Company's net loss and loss per
share would have been increased to the proforma amounts indicated below:

Prior to the KeySpan Acquisition, KSE had reserved for issuance 1,500,000 shares
of  nonqualified  stock  options  and had issued  426,000,  363,500  and 202,800
nonqualified stock options in November 1997, 1996 and 1995, respectively.  These
options have remained outstanding and, under the terms

<PAGE>




of the Merger  Agreement,  all options vested upon  consummation  of the KeySpan
Acquisition.  Holders are now permitted to exercise  vested  options for Company
common stock.

The fair  values of grants  issued in November  1997,  1996 and 1995 were $4.62,
$4.27 and $2.78,  respectively.  All grants were  estimated on the date of grant
using the  Black-Scholes  option-pricing  model. The following  weighted-average
assumptions  were  used for  grants  issued  in  November  1997,  1996 and 1995:
dividend yield of 5.00%, 4.66% and 5.57%;  expected volatility of 16.24%, 16.56%
and 16.879%;  risk free  interest rate of 6.00%,  6.00% and 6.28%;  and expected
lives of 6 years,  respectively.  The  exercise  prices are  $32.63,  $30.50 and
$27.00, respectively.

NOTE 7. LONG-TERM DEBT

Gas Facilities Revenue Bonds:  Brooklyn Union can issue tax-exempt bonds through
the New York State Energy Research and Development Authority. Whenever bonds are
issued for new gas  facilities  projects,  proceeds  are  deposited in trust and
subsequently withdrawn to finance qualified  expenditures.  There are no sinking
fund  requirements  on any of the Company's Gas  Facilities  Revenue  Bonds.  At
December 31, 1998,  Brooklyn Union had $648.5 million of Gas Facilities  Revenue
Bonds outstanding. The interest rate on the Variable Rate Series due December 1,
2020 is reset weekly and ranged from 2.48% to 4.23%  through  December 31, 1998,
at which time the average rate was 3.90%.

In December 1998, the Company  purchased a portfolio of securities  representing
direct purchase  obligations of the United States  Government.  These securities
were placed in trust,  irrevocably  dedicated  to the  repayment  of certain Gas
Facilities  Revenue  Bonds,  thereby  effecting an  in-substance  defeasance  of
approximately  $8.9 million  including  interest.  The  in-substance  defeasance
represented  $4 million of  outstanding  bonds of each of the 6.75% Series 1989A
due February 1, 2024 and 6.75%  Series  1989B due February 1, 2024.  The Company
has not been relieved of its obligation and remains the primary obligor for this
debt.  Based on the accounting  requirements  of SFAS No. 125,  "Accounting  for
Transfers  and  Servicing  of  Financial  Assets  and  the   Extinguishment   of
Liabilities," the liability is not considered  extinguished and is recognized on
the accompanying Consolidated Balance Sheet.

AUTHORITY FINANCING NOTES: The Company's electric generation subsidiary can also
issue   tax-exempt  bonds  through  the  New  York  State  Energy  Research  and
Development  Authority.  At  December  31,  1998,  $24.9  million  of  Authority
Financing Notes were  outstanding.  The interest rate on these notes is variable
and  ranged  from 2.65% to 4.75%  through  December  31,  1998 at which time the
average rate was 4.10%.

PROMISSORY NOTES: At March 31, 1998, total long-term debt outstanding was $4.497
billion. In accordance with the LIPA Agreement,  LIPA has assumed  substantially
all of the  outstanding  long-term  debt of LILCO  except for the 1997  Series A
Electric  Facilities  Revenue  Bonds due December 1, 2027 which were assigned to
the  Company.  In  accordance  with  the  LIPA  Agreement,  the  Company  issued
promissory  notes  to LIPA  for  $1.048  billion  which  represented  an  amount
equivalent to the sum of: (i) the principal amount of 7.3% Series Debentures due
July 15, 1999 and 8.2% Series  Debentures due March 15, 2023  outstanding at May
28, 1998,  and (ii) an allocation of certain of the Authority  Financing  Notes.
The promissory  notes contain  identical  terms as the debt referred to in items
(i) and (ii) above.

On November 3, 1998, the Company extinguished a portion of its obligation of the
promissory notes to LIPA relating to certain series of bonds that were called by
LIPA on  December  1, 1998.  The  Company's  obligation  for these bonds of $2.1
million  consisted of the principal  amount and the interest accrued and unpaid.
In addition, on December 1, 1998, the Company extinguished a portion

                                       81
<PAGE>




of its obligation of the promissory  notes on a certain series of bonds due to a
mandatory sinking fund redemption  payment of $1 million.  The carrying value of
the promissory notes at December 31, 1998 was $1.045 billion.

The  promissory  notes issued to LIPA included an allocation  for certain of the
Authority  Financing Notes.  Authority Financing Notes Series 1993B due November
1, 2023,  Series  1994A due October 1, 2024 and Series  1995A due August 1, 2025
have  variable  interest  rate features in which the interest rate is reset on a
weekly  basis.  The  interest  rates for these notes  ranged from 2.30% to 4.35%
during the nine months  ended  December  31, 1998 at which time the average rate
was 4.10%.  Authority  Financing Notes Series 1985A due March 1, 2016 and Series
1985B due  March 1,  2016 have  variable  interest  rate  features  in which the
interest rate is reset on an annual basis.  The interest rate for these notes at
December 31, 1998 was 3.58%.  On March 1, 1999, LIPA converted the variable rate
features of these notes to fixed interest rates.  Series 1993B, Series 1994A and
Series 1995A were converted to a fixed rate of 5.30% and Series 1985A and Series
1985B were converted to a fixed rate of 5.15%.

GENERAL &  REFUNDING  ("G&R")  MORTGAGE  BONDS:  Upon  consummation  of the LIPA
Transaction,  all of the series of G&R Bonds have been  assumed and  redeemed by
LIPA resulting in the termination of the G&R Mortgage.

OTHER LONG-TERM DEBT: THEC has an available line of credit of $150 million which
supports  borrowings under a revolving loan agreement.  Up to $5 million of this
line is available  for the issuance of letters of credit to support  performance
guarantees.  This credit facility matures on July 1, 2000. At December 31, 1998,
borrowings of $133 million were  outstanding  under this line of credit and $0.4
million was committed under outstanding letter of credit obligations. Borrowings
under this  facility  bear  interest,  at THEC's  option,  at rates indexed at a
premium to the Federal Funds rate or LIBOR rate, or based on the prime rate. The
weighted  average  interest  rate on this debt was 6.44% at December  31,  1998.
Covenants  related to this line of credit  require  the  maintenance  of certain
financial ratios and involve other  restrictions  regarding cash dividends,  the
purchase  or  redemption  of stock and the  pledging  of  assets.  Moreover,  at
December 31, 1998, THEC had $100 million of 8.625% Senior Subordinated Notes due
2008  outstanding.  These notes were issued in a private placement in March 1998
and are subordinate to borrowings under THEC's line of credit.

A subsidiary of the Energy  Related  Investment  segment had borrowings of $67.5
million  outstanding  at December 31, 1998, at an interest  rate of 5.25%.  Gulf
Midstream  Services  Partnership  ("GMS") was then provided with a loan of $64.8
million that bears interest on commercial terms.

DEBT MATURITY  SCHEDULE:  The total  long-term debt maturing in each of the next
five years ending  December 31 is as follows:  1999,  $398 million;  2000,  $1.0
million; 2001, $1.0 million; 2002, $3.5 million; and 2003, $3.5 million.

NOTE 8. CONTRACTUAL OBLIGATIONS,  FINANCIAL INSTRUMENTS AND CONTINGENCIES:

FIXED OBLIGATIONS:  Lease costs included in operation expense were $28.9 million
in 1998. The future minimum lease  payments under various  leases,  all of which
are  operating  leases,  are $22.1 million per year over the next five years and
$119.2 million, in the aggregate, for all years thereafter.

FIXED CHARGES UNDER FIRM  CONTRACTS:  The Company's  utility  subsidiaries  have
entered into various  contracts for gas delivery,  storage and supply  services.
The  contracts  have  remaining  terms that cover  from one to  fourteen  years.
Certain of these  contracts  require payment of monthly charges in the aggregate
amount  of $5.1  million  per  month in all  events  regardless  of the level of
service  available.  Such charges are  recovered  from utility  customers as gas
costs.

FAIR VALUE OF FINANCIAL  INSTRUMENTS:  The fair value of the Company's preferred
stock at December 31, 1998 was $471.6  million and the carrying value was $448.0
million.

The  Company's   long-term  debt  consists  primarily  of  publicly  traded  Gas
Facilities  Revenue Bonds,  Authority  Financing Notes and Debentures,  the fair
value of which is  estimated  on quoted  market  prices  for the same or similar
issues.  The  Authority  Financing  Notes and  Debentures  are  included  in the
promissory  notes to LIPA.  (See Note 2, "Sale of LILCO Assets,  Acquisition  of
KeySpan  Energy  Corporation  and  Transfer  of Assets  and  Liabilities  to the
Company" and Note 7, "Long-Term Debt" for additional information.)

The carrying amounts and fair values of the Company's long-term debt at December
31, 1998 and March 31, 1998 were as follows:

At December 31, 1998, THEC's $100 million 8.625% Senior  Subordinated  Notes due
2008 had a fair  market  value of $98  million.  All  other  THEC debt and other
subsidiary  debt is  carried  at an  amount  approximating  fair  value  because
interest  rates  are  based  on  current  market  rates.   All  other  financial
instruments  included in the  Consolidated  Balance  Sheet are stated at amounts
that approximate fair values.

DERIVATIVE  FINANCIAL  INSTRUMENTS:  The  Company's  utility,  marketing and gas
exploration and production subsidiaries employ derivative financial instruments,
such as natural  gas and oil  futures,  options  and swaps,  for the  purpose of
hedging exposure to commodity price risk.

Utility tariffs  applicable to certain  large-volume  customers permit gas to be
sold at prices  established  monthly  within a specified  range  expressed  as a
percentage of prevailing  alternate  fuel oil prices.  The Company uses standard
New York Mercantile  Exchange  ("NYMEX") futures contracts to fix profit margins
on  specified  portions  of the  sales  to  this  market  in line  with  pricing
objectives.  Implementation of the strategy involves establishment of long (buy)
positions in gas futures contracts with offsetting short (sell) positions in oil
futures  contracts of  equivalent  energy value.  The long gas futures  position
follows,  generally within a range of 80% to 120%, the cost of gas to serve this
market while the short oil futures position correspondingly  replicates,  within
the same range, the selling price of gas.

KeySpan  Energy  Services  ("KES"),  the  Company's  gas and electric  marketing
subsidiary,  sells gas at fixed annual rates and utilizes standard NYMEX futures
contracts and swaps to fix profit margins.  In the swap  instruments,  which are
employed to hedge  exposure to basis risk, KES pays the other parties the amount
by which the floating variable price (settlement price) is below the fixed price
and receives the amount by which the settlement price exceeds the fixed price.

THEC utilizes derivative commodity instruments to hedge future sales prices on a
portion of its natural gas production to achieve a more  predictable  cash flow,
as well as to reduce its exposure to adverse price  fluctuations of natural gas.
Hedging instruments used include swaps, collars and options. With respect to any
particular swap transaction,  the counter party is required to make a payment to
THEC in the event that the settlement  price for any  settlement  period is less
than the swap price for such  transaction,  and THEC is required to make payment
to the counter party in the event that the  settlement  price for any settlement
period is greater than the swap price for such  transaction.  For any particular
collar  transaction,  the counter party is required to make a payment to THEC if
the settlement price for any settlement period is below the floor price for such
transaction,  and THEC is required to make  payment to the counter  party if the
settlement  price for any settlement  period is above the ceiling price for such
transaction. For any particular floor transaction, the counter party is required
to make a payment to THEC if the settlement  price for any settlement  period is
below the floor  price for such  transaction.  THEC is not  required to make any
payment in connection with a floor transaction.  For option contracts,  THEC has
the option,  but not the  obligation,  to buy contracts up to the day before the
last trading day for that NYMEX contract.

As of December 31, 1998, no futures  contract  extended beyond May 2000.  Margin
deposits  with  brokers at December 31, 1998 of $10.7  million were  recorded in
Other in the Current Assets section of the Consolidated Balance Sheet.  Deferred
losses  on closed  positions  were $4.0  million  at  December  31,  1998.  Such
deferrals are generally recorded in net income within one month.

The  Company's  subsidiaries  are  exposed  to  credit  risk  in  the  event  of
nonperformance  by  counter  parties  to  derivative   contracts,   as  well  as
nonperformance by the counter parties of the transactions against which they are
hedged.  The  Company  believes  that the credit  risk  related to the  futures,
options and swap contracts is no greater than that  associated  with the primary
contracts which they hedge, as these contracts are with major  investment  grade
financial  institutions,  and that  elimination of the price risk lowers overall
business risk.

In addition to the derivative instruments discussed above, at December 31, 1998,
THEC had one interest rate swap agreement to exchange the differential between a
fixed  rate of  6.025%  and a market  LIBOR  rate  using an  aggregate  notional
principal of $30.0  million  over various  90-day  periods  from  November  1998
through November 1999.

LEGAL  MATTERS:  From time to time,  the  Company is  subject  to various  legal
proceedings  arising  out of the  ordinary  course  of its  business.  Except as
described  below,  the Company does not consider any of such  proceedings  to be
material to its business or likely to result in a material adverse effect on its
results of operations or financial condition.

Subsequent to the LIPA Transaction and KeySpan Acquisition,  former shareholders
of LILCO commenced 13 class action lawsuits in the New York State Supreme Court,
Nassau  County,  against each of the former  officers and directors of LILCO and
the Company.  These actions were  consolidated in August 1998. The  consolidated
action  alleges that in connection  with certain  payments  LILCO had determined
were payable in connection with the LIPA Transaction and KeySpan  Acquisition to
LILCO's chairman,  and to former officers of LILCO  ("Payments"):  (i) the named
defendants  breached  their  fiduciary  duty owed to LILCO and KSE former and/or
current  Company  shareholders  as a result  of the  Payments;  (ii)  the  named
defendants  intended  to defraud  such  shareholders  by means of  manipulative,
deceptive and wrongful conduct,  including materially  inaccurate and incomplete
news reports and filings with the  Securities and Exchange  Commission  ("SEC");
and (iii) the named defendants  recklessly and/or negligently failed to disclose
material facts associated with the Payments.

In addition,  three shareholder  derivative actions have been commenced pursuant
to which such  shareholders seek the return of the Payments or damages resulting
from among other things,  an alleged breach of fiduciary duty on the part of the
former LILCO officers and  directors.  One action was brought on behalf of LILCO
in federal  court.  The Company moved to dismiss this action in September  1998.
The other two  actions  were  brought on behalf of the Company in New York State
Supreme Court, Nassau County. In one of these state court actions, the Company's
directors and the recipients of the Payments are also named as defendants.

Finally,  two class action securities suits were filed in federal court alleging
that certain  officers and  directors of LILCO  violated the federal  securities
laws by failing to  properly  disclose  that the LIPA  Transaction  and  KeySpan
Acquisition  would trigger the  Payments.  These  actions were  consolidated  in
October 1998.

On March 17, 1999,  the Company signed a Memorandum of  Understanding  to settle
the  above-referenced  actions,  except the federal court derivative  action, in
exchange  for (i) $7.9 million to be  distributed  (less  plaintiffs'  attorneys
fees) to former LILCO and KSE shareholders  and (ii) the Company's  agreement to
implement certain corporate  governance and executive  compensation  procedures.
The entire $7.9 million settlement commitment will be funded from insurance. The
parties  intend to submit the  settlement to the Nassau County Supreme Court for
its review and approval. If that Court approves the settlement, the parties will
then make an application  to the federal court for an order and final  judgment,
dismissing  the  three  federal  court  actions,  including  the  federal  court
derivative action, based, among other things, on the binding effect of the state
court judgment.

In addition to the above mentioned actions, a class action lawsuit has also been
filed in the New York State  Supreme  Court,  Suffolk  County,  by the County of
Suffolk against LILCO's former officers and/or directors.  The County of Suffolk
alleges that the Payments were  improper,  and seeks to recover the Payments for
the benefit of Suffolk County ratepayers.  The Company moved to consolidate this
action with the above-mentioned consolidated action in October 1998.

In October 1998,  the County of Suffolk and the Towns of Huntington  and Babylon
commenced  an action  against  LIPA,  the  Company,  the NYPSC and others in the
United  States  District  Court  for  the  Eastern  District  of New  York  (the
"Huntington Lawsuit").  The Huntington Lawsuit alleges, among other things, that
LILCO  ratepayers  (i) have a property  right to receive or share in the alleged
capital gain that resulted from the transaction with LIPA (which gain is alleged
to be at least $1  billion);  and (ii)  that  LILCO  was  required  to refund to
ratepayers the amount of a Shoreham-related  deferred tax reserve (alleged to be
at least $800 million)  carried on the books of LILCO at the consummation of the
LIPA Transaction.  In December 1998, the plaintiffs amended their complaint. The
amended  complaint  contains  allegations  relating to the Payments and adds the
recipients  of the  Payments as  defendants.  In January  1999,  the Company was
served with the amended complaint.

Finally,  certain other proceedings have been commenced relating to the Payments
and disclosures made by LILCO with respect thereto.  These  proceedings  include
investigations by the New York State Attorney General, the NYPSC and LIPA, joint
hearings  conducted by two  committees  of the New York State  Assembly,  and an
informal,  non-public  inquiry by the SEC. In December 1998, the Company settled
with LIPA and the NYPSC. The agreement included a payment of $5.2 million by the
Company  to LIPA that will be used by LIPA to supply  postage-paid  bill  return
envelopes  to  customers  for the next three  years.  The Company also agreed to
fully  reimburse and  indemnify  LIPA for costs  incurred by LIPA,  amounting to
approximately  $765,000,  for  attorneys and other  consultants  involved in the
investigation.  Such  amounts  are not  covered  by  insurance.  The  Company is
cooperating fully with the investigations of the New York State Attorney General
and the SEC.  To date,  no action  has been  taken  either by the New York State
Attorney General or the SEC.

At this time the  Company is unable to  determine  the  outcome  of the  ongoing
proceedings, or any of the remaining lawsuits described above.

THE CLASS SETTLEMENT: The Class Settlement, which became effective in June 1989,
resolved a civil  lawsuit  against  LILCO  brought  under the federal  Racketeer
Influenced  and  Corrupt  Organizations  Act.  The  lawsuit,   which  the  Class
Settlement resolved,  had alleged that LILCO made inadequate  disclosures before
the NYPSC  concerning  the  construction  and  completion of nuclear  generating
facilities.   The  Class  Settlement   provided  electric  customers  with  rate
reductions of $390.0  million that were being  reflected as adjustments to their
monthly  electric bills over a ten-year period which began on June 1, 1990. Upon
its  effectiveness,  a liability  was  recorded  for the Class  Settlement  on a
present  value  basis at $170.0  million.  The Class  Settlement  obligation  of
approximately  $75.0  million at December 31, 1998 reflects the present value of
the  remaining  reductions  to be refunded to  customers.  The  reduction in the
present  value  of  this  liability  has  been  included  in  the   accompanying
Consolidated  Income Statement.  As a result of the LIPA Transaction,  LIPA will
reimburse  the remaining  balance to its electric  customers as an adjustment to
their monthly electric bills. The Company will then, in turn,  reimburse LIPA on
a monthly basis for such reductions on the customer's  monthly bill. The Company
remains ultimately obligated for the refund of the Class Settlement.

ENVIRONMENTAL  MATTERS:  The Company  has  recorded a $130.3  million  liability
associated with  investigation and remedial  obligations with respect to nine of
the Company's former  manufactured gas plants ("MGP").  Three of these MGP sites
are associated with Brooklyn  Union's  operations or its  predecessors;  six MGP
sites are associated with the operations of Brooklyn Union of Long Island or its
predecessors.  With respect to the former  Brooklyn  Union MGP sites, a total of
$48.3 million has been accrued  representing the best estimate of remedial costs
for one site and the minimum range of an estimate for the  investigation  and/or
remediation  of the other sites.  With respect to Brooklyn  Union of Long Island
MGP sites, a total of $82 million has been reserved as a minimum of an estimated
range of costs for the six sites which will be investigated/remediated  pursuant
to upcoming  Administrative  Orders on Consent ("ACO's") with the New York State
Department of Environmental  Conservation  ("DEC"). As the Company continues its
investigations and makes remedial decisions pursuant to its ACO obligations, the
environmental  conditions at each site will be clarified and the Company's total
remedial obligations are likely to be higher.

Under prior rate orders,  the NYPSC has allowed recovery of investigation  costs
related to certain  Brooklyn Union MGP sites.  Therefore,  at December 31, 1998,
the Company had reflected a total remaining  regulatory  asset of  approximately
$100.5 million.  The Company  believes that current rate plans in effect provide
for recovery of environmental costs.

Consolidated  earnings  for the  eight  months  ended May 28,  1998 were  $120.0
million, or $2.35 per share. Core utility operations  contributed $136.7 million
or $2.68  per  share.  THEC  contributed  $12.5  million  or $0.24  per share to
earnings,  while Energy Related  Investments had a loss of $6.2 million or $0.12
per share and Energy Related Services showed a loss of $6.5 million or $0.13 per
share,  reflecting  the effect of various costs  related to market  development.

prime  heating  months of November  through April when total annual gas revenues
are  substantially  realized.  Losses are  incurred  for the period May  through
September  and have not been  reflected in these  results.  In  addition,  $16.5
million or $0.32 per share of primarily merger related expenses were recorded by
KSE's   administrative  and  service  area  and  were  not  allocated  to  KSE's
subsidiaries.  Cash provided by operating  activities for the eight months ended

The accounting  policies of the segments are the same as those  described in the
summary of significant  accounting  policies.  The Company's reportable segments
are  strategic  business  units  that are  managed  separately  because of their
different  operating  and  regulatory   environments.   The  reportable  segment
information is as follows:

NOTE 11. COSTS RELATED TO THE LIPA TRANSACTION AND SPECIAL CHARGES

Special  charges for the nine months ended December 31, 1998 were $258.5 million
after-tax.  These charges reflected,  in part,  non-recurring charges associated
with the LIPA  Transaction  of $107.9 million  after-tax.  Costs relating to the
LIPA Transaction  principally reflected taxes associated with the sale of assets
(the  "Transferred  Assets") to the Company by LIPA;  the  write-off  of certain
regulatory assets that were no longer recoverable under various LIPA agreements;
and other transaction  costs incurred to consummate the LIPA Transaction.  These
charges were offset,  in part, by tax benefits  relating to the deferred federal
income taxes necessary to account for the difference between the carryover basis
of the Transferred Assets for financial reporting purposes and the new increased
tax  basis  of the  assets,  and  tax  benefits  recognized  on the  funding  of
post-employment benefits for employees of the successor company.


Further,  the Company  incurred  charges  related to the KeySpan  Acquisition of
$83.5  million  after-tax.  These charges  reflected a $42.0  million  after-tax
charge for an early retirement program initiated by the Company in December 1998
in which approximately 600 employees participated, and a $41.5 million after-tax
charge for the write-off of a customer  billing system that was in  development.
Also, in December 1998, the Company made a $20.0 million donation ($13.0 million
after-tax) to establish the KeySpan Foundation,  a not-for-profit  philanthropic
foundation that will make donations to local charitable community organizations.

Special charges also reflected an after-tax  impairment charge of $54.1 million,
which represented the Company's share of the impairment charge,  recorded by the
Company's gas and oil exploration and production  subsidiary to reduce the value
of its proved gas reserves in accordance with the asset ceiling test limitations
of the  Securities and Exchange  Commission  applicable to gas  exploration  and
development operations accounted for under the full cost method.

NOTE 12. SUPPLEMENTAL DISCLOSURE OF KSE AND SUBSIDIARIES (UNAUDITED)

For the twelve  months ended  December  31, 1998 net income of the  consolidated
entities  comprising  KSE was $12.5 million  compared to $126.3  million for the
1997 corresponding period. Net income in 1998 was affected by rate reductions to
gas utility  customers;  significantly  warmer than  normal  weather  during the
period; certain special charges associated with the KeySpan Acquisition of $23.5
million  after-tax,  including  charges  associated  with the  early  retirement
program; and an impairment charge of $54.1 million after-tax to reduce the value
of proved gas reserves. Energy Related Investment earnings for the twelve months
ended December 31, 1997 reflected the sale of certain subsidiary  properties for
$15.2 million  after-tax.  Consolidated  net income  together with the effect of
special charges, is set forth in the following table:

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

Earnings from Gas  Distribution  operations for the twelve months ended December
31,  1998 were  impacted by synergy  savings-related  rate  reductions  of $23.9
million effective May 29, 1998.  Brooklyn Union core customers have received the
benefits of these reductions before actual savings


                                       92

<PAGE>




could be achieved.  Moreover,  in 1998 results  were  affected by  significantly
warmer  than  normal  weather.  Weather  was 18% warmer  than  normal in 1998 as
compared to normal  weather  experienced  in 1997. The effects of weather on Gas
Distribution   revenues  is  largely  mitigated  by  the  weather  normalization
adjustment  included  in  Brooklyn  Union's  tariff;  nevertheless,  significant
fluctuations  in normal  weather  will affect  revenues  collected  from heating
customers. The effects of the rate reduction and the significantly warmer winter
heating season reduced net revenues,  revenues less gas costs,  by $24.2 million
for the twelve months ended  December 31, 1998 as compared to the  corresponding
period last year.

The  aforementioned  variations  in net  revenues  were  totally  offset by cost
reduction measures and re-engineering  processes employed by KSE during the past
few years.  Further,  operation and maintenance expense was lower in 1998 due to
the exceptionally warm weather experienced. Earnings from gas utility operations
provided an equity return, including discrete incentives,  of 13.6% for the rate
year  ending  September  30,  1998 as compared to 13.5% for the rate year ending
September 30, 1997.

Earnings  from  Gas  Exploration  and  Production  activities  in 1998  and 1997
reflected the continued expansion of operations, primarily in Texas and the Gulf
of Mexico, by THEC.  Earnings in 1998, however,  were significantly  affected by
low gas production  prices.  Included in special  charges above, is an after-tax
charge of $54.1 million representing the Company's share of an impairment charge
recorded by THEC to reduce the value of its investment in proved gas reserves in
accordance  with the  asset  ceiling  test  limitations  of the  Securities  and
Exchange Commission.

Revenues from gas production activities increased in 1998 as compared to 1997 by
approximately  9% due  primarily  to the  continued  development  of  additional
natural  gas  properties  acquired  by THEC  during  the past three  years.  The
benefits  derived from  increased  production  levels,  however,  were partially
offset,  by decreases in average realized prices.  In 1998,  production was 62.8
billion cubic feet (BCFe), or 11.5 BCFe above the level of production last year.
In 1998,  wellhead  prices averaged $1.96 per MCF compared with $2.45 per MCF in
1997.  The  effective  price  realized  (average  wellhead  price  received  for
production  including  recognized hedging gains and losses) was $2.02 per MCF in
1998  compared  with  $2.25  per  MCF  in  1997.  Further,  operating  expenses,
including,  depreciation,  depletion  and  amortization  expense,  increased  by
approximately 30% for the year ended December 31, 1998 as compared with the year
ended December 31, 1997 due primarily to increased production activity.

Earnings from the Energy Related  Investments  segment  consists of results from
the  Company's  20%  interest  in the  Iroquois  Gas  Transmission  System  LP ,
investments in The Premier Transco  Pipeline and Phoenix Natural Gas in Northern
Ireland and investments in midstream  natural gas assets in Western Canada owned
jointly with Gulf Canada Resources Limited. Results from these investments,  for
the year  ended  December  31,  1998,  reflected  the  start-up  nature of their
operations,  while  results  relating  to the  investment  in the  Iroquois  Gas
Transmission  System  for  1998  and  1997  were  consistent  with  management's
expectations  and  reflected  after-tax  earnings of $6.5  million.  The Company
completed its acquisition of midstream natural gas assets in Western Canada in



                                       93
<PAGE>




December  1998, and therefore,  earnings from this  investment  will begin to be
realized in fiscal year 1999.  Results also  reflected  costs to settle  certain
contracts  associated  with  the  sale of the  Company's  domestic  cogeneration
investments and fuel management  operations,  which took place in 1997. Earnings
in 1997 primarily reflected the sale of certain Canadian properties and the sale
of domestic cogeneration investments and fuel management operations.

Subsidiaries  comprising the Energy Related Services segment incurred losses for
the past two years reflecting the start-up nature of their operations.  Included
in this business  segment are operations  which market gas and  electricity  and
arrange  transportation  and  related  services,  largely  to retail  customers,
including  those  served by the  Company's  gas  distribution  subsidiaries.  In
addition,  these  subsidiaries  provide a variety of technical  and  maintenance
services to customers  that operate  commercial  and  industrial  facilities and
provide  appliance repair service to residential  customers,  all located within
the New York City metropolitan  area. During the past two years, the Company has
acquired  an  engineering   firm,  and  major  heating,   ventilation   and  air
conditioning contractors and has integrated these operations into its strategies
for future growth.

Results from the Other segment reflected certain costs associated with corporate
and  administrative  functions  that  were not  allocated  to  various  business
segments.

NOTE 14.  SUPPLEMENTAL GAS AND OIL DISCLOSURES (CONTINUED)


The gas and oil reserves  information  is based on estimates of proved  reserves
attributable  to  THEC's  interest  as of  December  31 for  each  of the  years
presented.  These estimates  principally were prepared by independent  petroleum
consultants.  Proved reserves are estimated  quantities of natural gas and crude
oil which geological and engineering data demonstrate with reasonable  certainty
to be recoverable in future years from known reservoirs under existing  economic
and operating conditions.


The  standardized  measure of  discounted  future net cash flows was prepared by
applying year-end prices of gas and oil to the proved reserves, except for those
reserves devoted to future  production that is hedged.  Such reserves are priced
at their respective hedged amounts.  The standardized  measure does not purport,
nor should it be  interpreted,  to present  the fair value of THEC's gas and oil
reserves.  An estimate of fair value would also take into  account,  among other
things, the recovery of reserves not presently classified as proved, anticipated
future changes in prices and costs and a discount factor more  representative of
the time value of money and the risks inherent in reserve estimates.

REPORT OF ARTHUR ANDERSEN LLP, INDEPENDENT PUBLIC ACCOUNTANTS

To the  Shareholders  and Board of Directors  of  MarketSpan  Corporation  d/b/a
   KeySpan Energy:

We have audited the  accompanying  Consolidated  Balance Sheet and  Consolidated
Statement of Capitalization  of MarketSpan  Corporation (a New York corporation)
and subsidiaries as of December 31, 1998 and the related Consolidated Statements
of Income,  Retained  Earnings and Cash Flows for the nine months ended December
31, 1998.  These financial  statements are the  responsibility  of the Company's
management.  Our  responsibility  is to express  an  opinion on these  financial
statements based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards  require that we plan and perform the audit to obtain reasonable
assurance   about  whether  the  financial   statements  are  free  of  material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material  respects,  the financial position and capitalization of MarketSpan
Corporation  and  subsidiaries  as of December 31, 1998 and the results of their
operations  and their cash flows for the nine months ended December 31, 1998, in
conformity with generally accepted accounting principles.

Our  audits  were  made for the  purpose  of  forming  an  opinion  on the basic
consolidated  financial statements taken as a whole. The schedule listed in Item
14 is the  responsibility  of the Company's  management and is presented for the
purpose of complying with the Securities and Exchange  Commission's rules and is
not part of the basic consolidated financial statements.  This schedule has been
subjected  to the  auditing  procedures  applied  in  the  audits  of the  basic
consolidated  financial  statements  and, in our opinion,  fairly  states in all
material  respects  the  financial  data  required  to be set forth  therein  in
relation to the basic consolidated financial statements taken as a whole.

of January, 1997, is entered into by and between The Brooklyn Union Gas Company,
a New  York  corporation,  hereinafter  referred  to by  name or  either  as the

      Subject to the provisions for termination  hereinafter set forth, the term
of this  Agreement  shall  commence on the  effective  date hereof and expire on
January  1,  2000;  provided,  however,  that this  Agreement  shall  extend for
successive one-year renewal terms thereafter unless terminated by six (6) months
prior written notice from one party to the other prior to the termination of the
initial or any renewal  term.  The initial term  together with any renewal terms
hereto are hereinafter referred to as the "Term".

                                  ARTICLE II
                               EXECUTIVE DUTIES
      Subject to the terms and conditions  set forth herein,  the Company hereby
employs  Employee,  and Employee  hereby accepts  employment by the Company,  to
serve as Senior Vice President,  Strategic  Planning & Corporate  Development of
the  Company,  and to perform the duties  attendant to such  position.  Employee
shall  perform  such  duties  for the  position  described  herein  in a  manner
consistent  with the  performance  expectations  and standards  established  and
communicated to the


<PAGE>

require, and shall not during the term of his employment hereunder be engaged in
any other  business  activity  pursued  for  gain,  profit  and other  pecuniary
advantage if such activity  materially  interferes  with  Employee's  duties and
responsibilities  hereunder.  However,  the foregoing  limitations  shall not be
construed as prohibiting Employee from making personal  investments  (including,
but not limited to, the trading of natural  gas,  crude or  electricity  futures
contracts on the NYMEX, or other private investment  activity in publicly traded
stocks of energy related concerns on any public exchange) in such form or manner
as will  neither  require him  materially  to  participate  in the  operation or
affairs of the companies or enterprises in which such  investments  are made nor
violate  the terms of The  Brooklyn  Union Gas  Company's  Statement  of Ethical
Business  Conduct and of Article VII hereof.  Employee may also  participate  in
social, civic, charitable,  religious,  educational or professional associations
so long as such  participation  would not  materially  detract  from  Employee's
ability to perform his duties under this Agreement.

in equal monthly  installments on or about the 15th day of each month during the
Term hereof.  With respect to increases in Base  Compensation  based upon merit,
performance,  cost of living,  or  otherwise,  such Base  Compensation  shall be

Company's  Corporate  Incentive  Compensation  Plan as it may exist from time to
time. The Incentive Compensation shall be paid to Employee pro rata based on the
number of days of  employment  in the year for any partial  years of  employment
hereunder,  except  that,  for  the  first  year  of  this  Term  any  Incentive
compensation  due Employee at the close of fiscal 1997 shall be  calculated  and
paid on a full year basis as if (i) Employee had initiated  employment effective
with  the  fiscal  year of the  Company  on  October  1,  1996 and (ii) the Base
Compensation  (for purposes of calculation of each Incentive  Compensation ) had
begun on October 1, 1996 as well.  The Employee  shall also  participate  in all
applicable  Deferred  Compensation  Plans  of the  Company,  including,  but not
limited to, such plan as adopted on November 15, 1995  entitled  the  "Long-Term

similarly  appointed or elected senior officers of the Company, or subsequently,
the Holding Company.


<PAGE>

Company shall tender to Employee  immediately upon execution of this Agreement a

Bonus") based upon (i)  exceptional  performance  demonstrated  by Employee as a
Consultant to the Company in fiscal 1996, and (ii)  Employee's  contribution  to
future  earnings  per share  while  serving  in his  Consultant  capacity,  such

            allowance consistent with Company policy for
      senior  executive level officers of the Company plus  insurance,  fuel and
      maintenance. Given Employee's obligation to relocate to the New York area,
      it shall be  permissible  for  Employee  to apply  such  allowance  to his
      existing vehicle.
            (vii) The Company shall reimburse  Employee for reasonable  expenses
      incurred for tax and personal accounting services not to exceed $2,000 per

      selection of Employee.

      enable   Employee  to  relocate  his  principal   residence  and  personal
      belongings  of his immediate  family from Houston,  Texas to the principal
      headquarters in New York City or the greater Tri-State area. To facilitate
      the  relocation  of  Employee  to the New York  area,  the  Company  shall
      reimburse  Employee  his actual  costs  incurred in  connection  with such
      relocation up to a maximum of $120,000. Employee shall provide appropriate
      receipts and documentation to the Company. An advance  reimbursement under
      this Paragraph of $50,000 shall be made


<PAGE>



      to Employee as soon as practicable after execution of this Agreement.  The
      Company will  endeavor to diminish  income tax  exposure to Employee  with
      respect to utilization  and  expenditure  of such  Relocation  Funds.  The
      Employee  shall be entitled to utilize  such  Relocation  Funds toward any
      expenditure which may, directly or indirectly,  result from the relocation
      of  Employee  and his family to New York from  Texas,  including  (but not
      limited to) expenses such as the payment of Employee's  existing  mortgage
      in Houston along with the timely payment of insurance, taxes, assessments,
      utilities,  yard and pool  maintenance  beginning  with the effective date
      hereof and continuing  thereafter until either the Employee's residence is
      sold.  With  respect to the sale of  Employee's  residence  in Texas,  the
      Relocation Funds shall include  applicable  brokerage  fee's,  closing and
      related  costs,  and shall also be used to  compensate  any loss in equity
      calculated  upon the original  purchase price of $542,5000.  Additionally,
      the Relocation  Funds shall include  temporary  living expenses within the
      Tri-State area such as monthly rentals, utilities,  insurance,  applicable
      real property taxes and maintenance. In the event the Relocation Funds are
      not exhausted  after all direct cost receipts are  reimbursed to Employee,
      the residue balance of such Relocation Funds shall be provided to Employee
      to reflect  reimbursement  for the increased  cost-of-living  differential
      between Houston,  Texas and New York City.  Finally,  reasonable  expenses
      such as  moving,  interim  airfare,  lodging,  meals,  transportation  and
      similar  expenses  incurred by Employee or his  immediate  family shall be
      covered  by such  Relocation  Funds.  With  respect to  on-going  business
      expenses  (E.G.  hotel,  meals,  transportation  and airfare)  incurred by
      Employee  during the period of January 1, 1997 thru  January 31, 1997 as a
      result of the pendency of


<PAGE>



      Board and other appropriate  employment approvals and, taking into account
      the timing for negotiation of definitive relocation provisions, submission
      of Employee to the Board of Directors for  candidate  approval as a senior
      executive  officer of the Company,  and then final execution  hereof,  the
      Company shall continue to be responsible for Employee's  business expenses
      and all  business  related  travel,  lodging,  meals and similar  expenses
      incurred by Employee.  Such business expenses incurred during January 1997
      shall not be considered part of the Relocation Funds.

                              DUTIES OF EMPLOYEE
      (a) Employee's  duties shall be those which are  customarily  attendant to
his position  described above.  Employee  recognizes and agrees that he owes the

in the best  interests  of the Company  and to do no act which would  injure the

shall extend  throughout  the term of his  employment  hereunder and shall apply
after  termination of such  employment to the extent set forth in this Agreement
and as recognized by law.
      (b) In keeping with  Employee's  fiduciary  duty to the Company,  Employee
agrees that  during his  employment  hereunder,  he shall not  knowingly  become
involved in a conflict between his personal  interests and those of the Company,
and upon  discovery  thereof,  shall not allow  such  conflict  of  interest  to
continue.

                                 ARTICLE VII
                                NONCOMPETITION

<PAGE>



Article VII.
(A) Except as provided for under Article II of this  Agreement,  while  employed
hereunder  and for  the  greater  of (i) a  period  of one  year  following  the
termination of this Agreement by reason of the expiration of its Term as defined
in Article I hereof or (ii) the  remainder  of the Term,  if this  Agreement  is
terminated  before such expiration as defined in Article I hereof,  whichever is
longer, (the "Restricted Period"), neither Employee or corporation,  partnership
or other entity  controlled by or under common control with Employee will (a) in
the States of New York, New Jersey and Connecticut  travel,  canvas or advertise
for,  or  otherwise  assist,  render  services  to,  become  employed  by,  be a
consultant to, or invest in any business  entity or with any individual  engaged
in, or engage  directly or indirectly in, any line or liens of business  carried
on or  contemplated  which,  directly  or  indirectly,  is a  competitor  of the
Company,  (b) solicit business or otherwise deal directly or indirectly with any
customers  or persons who were  employees of customers or vendors of the Company
at any time,  (c)  directly or  indirectly  divert or attempt to divert from the
Company, any business in which it has been engaged during the Term of Employee's
employment  with the  Company,  or in which it might  reasonably  be expected to
become  engaged,  (d) directly or  indirectly  interfere or attempt to interfere
with the  relation  ships  between the  Company,  its  customers,  employees  of
customers  or  vendors,  (e)  directly  or  indirectly  interfere  or attempt to
interfere with the relationship of  employer-employee  or principal and agent of

terms of this Paragraph from investing in and owning not more than one percent


<PAGE>



(1%) of the  outstanding  shares of common stock of any  corporation  engaged in
similar  business  to the  Company,  the  shares  of which are  publicly  traded
pursuant to the Securities  Exchange Act of 1934,  and/or  passively invest as a
limited partner in any  non-publicly  traded security similar to the business of
the Company.  (B) Employee has carefully  read and  considered the provisions of
this Article VII and, having done so, agrees that the  restrictions set forth in
this  Article  are fair and  reasonable,  and are  reasonably  required  for the
protection of the Company,  its officers,  directors,  employees,  creditors and
shareholders.  Employee  understands  that the  restrictions  contained  in this
Article  may limit his  ability to engage in a business  similar to the  Company
business,  but acknowledges that he will receive  sufficiently high renumeration
and other benefits from the Company hereunder to justify such restrictions.  (c)
In the event that any  provision of this Article VII relating to the  Restricted
Period and/or the areas of restriction shall be declared by a court of competent
jurisdiction  to exceed  the  maximum  time  period or areas  such  court  deems
reasonable  and  enforceable  by the court shall  become and  thereafter  be the
maximum time period and/or areas.

                                 ARTICLE VIII
                               CONFIDENTIALITY
      The Employee agrees that all payments,  compensation, and benefits payable
to the  Employee  under  this  Agreement  shall  be  subject  to the  Employee's
compliance with the provisions of this Article VIII.


<PAGE>



(A) Employee  recognizes  that the services to be performed by him hereunder are
special,  unique,  and  extraordinary and that, by reason of his employment with
the Company, he may acquire Confidential Information concerning the operation of
the Company,  the use or disclosure of which would cause the Company substantial
loss and damages which could not be readily  calculated  and for which no remedy
at law  would  be  adequate.  Accordingly,  Employee  agrees  that he  will  not
(directly or  indirectly)  at any time,  whether  during or after his employment
hereunder,  (i) knowingly use for an important personal benefit any Confidential
Information  that he may learn or has learned by reason of his  employment  with
the Company or (ii)  disclose any such  Confidential  Information  to any person
except (a) in the performance of his obligations to the Company  hereunder,  (b)
as required by applicable  law, (c) in connection  with the  enforcement  of his
rights under this Agreement, (d) in connection with any disagreement, dispute or
litigation  (pending or threatened) between Employee and the Company or (e) with
the  prior  written  consent  of  the  Board  of the  Company.  As  used  herein
"CONFIDENTIAL  INFORMATION"  includes  information with respect to the Company's
products,  facilities and methods,  research and development,  trade secrets and
other  intellectual   property,   systems,   patents  and  patent  applications,
procedures,  manuals, confidential reports, product price lists, customer lists,
financial  information,  business plans,  prospects or opportunities;  PROVIDED,
HOWEVER, that such term shall not include any information that (x) is or becomes
generally  known or available other than as a result of a disclosure by Employee
or (y) is or becomes known or available to Employee on a  nonconfidential  basis
from a source (other than the Company),  which, to Employee's knowledge,  is not
prohibited from disclosing such information to Employee by a legal, contractual,
fiduciary or other obligation to the Company.


<PAGE>



(B)  Employee  confirms  that  all  Confidential  Information  is the  exclusive
property of the company. All business records, papers and documents kept or made
by  Employee  while  employed by the  Company  relating  to the  business of the
Company  shall be and remain the property of the Company at all times.  Upon the
request  of the  Company at any time,  Employee  shall  promptly  deliver to the
Company  and  shall  retain  no copies of any  written  materials,  records  and
documents made by Employee or coming into his  possession  while employed by the
Company  concerning  the business or affairs of the Company  other than personal
materials,  records  and  documents  (including  notes  and  correspondence)  of
Employee not  containing  proprietary  information  relating to such business or
affairs.

                              INJUNCTIVE RELIEF
      Employee  acknowledges that a breach of any of the covenants  contained in
this Article VIII may result in material  irreparable  injury to the Company for
which  there is no  adequate  remedy  at law,  that it will not be  possible  to
measure the damages for such  injuries  precisely and that, in the event of such
breach, any payments remaining under the terms of this Agreement shall cease and
the Company  shall be entitled to obtain a temporary  restraining  order  and/or
preliminary  or  permanent  injunction  restraining  Employee  from  engaging in
activities  prohibited  by this  Article  VII or  such  other  relief  as may be
required to specifically  enforce any of the covenants contained in this Article
VIII.  Employee agrees to and hereby does submit to IN PERSONA injunction in the
appropriate courts of the State of New York.  Employee agrees that the rights of
the Company to obtain an injunction  granted by this  Paragraph of the Agreement
shall not be considered a waiver of its rights to assert


<PAGE>



any other remedies it may have at law or in equity.

                                  ARTICLE IX
                              DEATH OF EMPLOYEE
      In the event of the death of Employee during Employee's term of employment
hereunder,  the Company shall pay to Employee's estate (i) the Base Compensation
which would  otherwise by payable to Employee under this Agreement up to the end
of the  month  in which  such  death  occurs;  (ii) the  Signing  Bonus  and the
Incentive  Compensation,  if any,  which may become  payable to Employee for the
period  prior to the date of death;  and (iii) all  other  benefits  which  have
accrued to date of Employee's death,  including any Deferred  Compensation under
the Company's deferred Compensation Plan.

                                  ARTICLE X
                            MANDATORY ARBITRATION
      (a) Any dispute,  controversy,  or claim arising out of or relating to any
provision of this Agreement or the interpretation,  enforceability, performance,
breach,  termination,  or validity hereof,  including,  but not limited to, this
arbitration   clause  shall  be  solely  and  finally  settled  by  confidential
arbitration  in the  State of New  York,  in  accordance  with the  Rules of the
American  Arbitration  Association  ("AAA") as modified by the provision of this
Article X.
      (b)  To  the  extent  this  Article  X is  deemed  a  separate  agreement,
independent  from this Agreement,  Article XIV hereof is incorporated  herein by
reference.


<PAGE>



      (c)  The  arbitration   shall  be  conducted  by  a  panel  of  three  (3)
arbitrators,  selected in the following manner:  each party shall select one (1)
arbitrator  within  twenty  (20) days from the date of  receipt of the demand to
commence  arbitration.  If one or both  of the  parties  fails  to  nominate  an
arbitrator,  the AAA shall have the power to select an arbitrator on the party's
behalf.  Within ten (10) days after the  appointment  of the last of the two (2)
arbitrators,  the selected party  arbitrators shall choose a third arbitrator to
serve as the neutral chairman of the panel.
      (d) The parties agree that the provisions of this Article X, including the
rules of the AAA and the laws of the State of New York and the United  States of
America,  as  modified  by the  terms  of  this  Article  X,  shall  govern  the
arbitration of any disputes arising pursuant to this Agreement.  In the event of
any  conflict  between  the  laws of the  State  of New  York  and  the  Federal
Arbitration  Act (9 U.S.C.ss.  et seq.  (1988)) with respect to any  arbitration
conducted  pursuant  to this  Agreement,  to the extent  permissible,  it is the
express  intent of the parties that the law of the Federal  Arbitration  Act, as
modified by this Article X, shall prevail.
      (e) All papers,  documents,  or evidence,  whether written or oral,  filed
with or  presented  to the  arbitrator  shall be deemed by the  parties  and the
arbitrator to be confidential information. No party, expert, or arbitrator shall
disclose in whole or in part to any other  person any  confidential  information
submitted by any other person in connection with arbitration proceedings, except
to the extent (i) required by law or regulation,  (ii)  reasonably  necessary to
assist counsel in the arbitration or preparation for arbitration of the dispute,
or (iii) that such  confidential  information  was  previously,  or subsequently
becomes,  known to the disclosing  party,  or becomes  publicly known through no
fault of the  disclosing  party.  Confidential  information  may be disclosed to
attorneys,


<PAGE>



parties,  and  qualified  outside  experts  requested by any party's  counsel to
furnish  technical or expert  services or to give  testimony at the  arbitration
proceedings;  provided,  however,  that  such  persons  agree  to  maintain  the
confidentiality of such disclosures to them.
            All oral and written  communications  between the parties  issued or
prepared in connection with attempted resolution of any disputes hereunder shall
be deemed to have been  prepared and  communicated  in  furtherance,  and in the
context,  of  dispute  settlement,  and  shall  be  exempt  from  discovery  and
production,  and shall not be admissible as evidence (whether as an admission or
otherwise), in any proceedings for the resolution of the dispute.
      (f) The parties  shall be entitled to  discover  all  documents  and other
information  reasonably  necessary for a full  understanding  of any  legitimate
issue raised in the arbitration. They may use all methods of discovery customary
under New York law, including, but not limited to, depositions,  interrogatories
and requests for admission.  The time periods for compliance shall be set by the
arbitrator, who may also set limits on the scope of such discovery.
            The arbitrator is empowered to issue, on ex parte application of any
party or on his own volition,  any subpoena (including any subpoena duces tecum)
in accordance  with any provision of applicable  law, and to make such orders as
may be necessary for the  arbitrator or persons  designated by the arbitrator to
obtain appropriate or necessary evidence.
            The New York Rules of Evidence shall apply to the proceedings.

     (g)  The  arbitrator  is  empowered  to  render  the  following  awards  in
accordance  with any  provision of this  Agreement:  (i)  enjoining a party from
performing  any act  prohibited,  or  compelling  a  party  to  perform  any act
required, by the terms of this Agreement and any order entered pursuant


<PAGE>



to this  Agreement or deemed  necessary by the  arbitrator  to resolve  disputes
arising  under or  relating to this  Agreement  or order;  (ii) where,  and only
where,  violations of this Agreement have been found,  shortening or lengthening
any period established by this Agreement or order; and (iii) ordering such other
legal or equitable relief,  including any provisional legal or equitable relief,
or specifying such procedures as the arbitrator  deems  appropriate,  to resolve
any dispute submitted to it for arbitration.
      (h) An award rendered in connection  with an arbitration  pursuant to this
Article X shall be final and binding  upon the parties,  and any  judgment  upon
such  an  award  may  be  entered  and   enforced  in  any  court  of  competent
jurisdiction.
      (i)  Notwithstanding any other provision hereof which may appear to be the
contrary, the parties specifically covenant and agree that no party hereto shall
be entitled to assert any demand for or recover  any  consequential  or punitive
damages,  but that the collection of actual  damages shall be full  compensation
and satisfaction for any breach hereof.
            The parties  agree that the award of the arbitral  tribunal  will be
the sole and  exclusive  remedy  between them  regarding  any and all claims and
counterclaims  between them with respect to the subject matter of the arbitrated
dispute. The parties hereby waive all jurisdictional defenses in connection with
any  arbitration  hereunder or the  enforcement  of any order or award  rendered
pursuant  thereto  (assuming that the terms and  conditions of this  arbitration
clause have been complied with).
            The parties hereby agree that the  relationship  between the parties
is commercial in nature,  and that any disputes  between the parties  related to
this Agreement shall be deemed


<PAGE>



commercial.
      (j) The  arbitrator  shall  apportion  to each party all costs (other than
attorneys'  fees which shall be the  separate  cost of each  party)  incurred in
conducting the  arbitration in accordance  with what he deems most and equitable
under the circumstance.  Any party wishing to make a stenographic  record of the
proceedings may do so at its own expense.

                                  ARTICLE XI
                                 SERVABILITY
      In the event any  provisions  of this  Agreement are held to be invalid or
nonenforceable,  such invalid or  nonenforceable  provisions  shall be separable
from the remainder of the Agreement,  and the remainder of this Agreement  shall
be unaffected by the invalid or nonenforceable provision.

                                 ARTICLE XII
                               ENTIRE AGREEMENT
      This Agreement  constitutes the entire agreement and understanding between
the Company and Employee, whether express or implied, with respect to Employees'
employment  by the  Company  and  supersedes  any and all prior  agreements  and
understandings,  whether  written,  oral or  otherwise,  relating to the subject
matter of this Agreement; provided, however, that the provisions of the Conflict
of Interests and Confidentiality Policies of the Company shall not be superseded
by but shall supplement the terms of this Agreement.

                                APPLICABLE LAW

York. IN WITNESS WHEREOF, the execution hereof shall be effective as of the date

Product")  shall  belong  exclusively  to the Company  and shall,  to the extent

full and proper effect to such assignment.

9.    Confidentiality.

      (a) As a fiduciary of the Company,  the  Executive  agrees not to disclose
any  confidential  information  made available to or learned by the Executive in
the course of the performance of the Executive's  duties at the Company and with
respect to the business of the Company.

      For  the  purposes  of  this  Section,   the  term  "confidential"   means
information disclosed to the Executive or known, learned, created or observed by
the Executive as a consequence of, or through the Executive's  employment by the
Company  concerning the Company or any parent,  subsidiary or affiliated company
which is  presently  existing  or which may be formed  in the  future,  which is
confidential,  secret or otherwise  not  generally  known in the  industry,  and
pertains directly or indirectly to the business activities,  products, services,
customers  or  processes  of Company or any of its  subsidiaries  or  affiliated
companies,  including, but not limited to, information concerning mailing lists,
publicity,  data,  research,  copy,  other printed matter,  photographs,  films,
reproductions,  finances,  processes,  trade secrets,  business plans,  customer
lists and records,  potential customer lists, customer billing and other related
information.

      The Executive shall not take any original or copy of any document or other
papers, computer diskettes,  methods, procedures, etc., containing or disclosing
such confidential information or documents or summaries containing the substance
of any part  thereof.  Any  records  of  confidential  information  prepared  by
Executive  or which came into the  Executive's  possession  during the period of
employment  with the Company are and remain the property of the Company and upon
termination of Executive's employment, all such records and copies thereof shall
either be left with or returned to Company.

      (b) The Executive agrees that the  restrictions  contained in Section 9(a)
of this  Agreement are necessary  for the  protection of the Company  during and
following the Terms of Employment  hereunder,  and any breach thereof will cause
the  Company  damage for which  there are no  adequate  remedies  at law and the
Executive  consents to the issuance of an injunction in favor of the Company and
its successors and assigns enjoining the breach of the aforesaid restrictions by
any court of competent jurisdiction. The Executive agrees that the rights of the
Company to obtain an injunction granted by this paragraph of the Agreement shall
not be  considered  a waiver of the  rights of the  Company  to assert any other
remedies they may have at law or in equity.



<PAGE>



10.   Non-competition.

      (a) The Executive  acknowledges that, while serving Company, the Executive
will have  numerous,  extensive  and  controlling  contacts  with the  Company's
customers  and will  provide  unique and special  services to the  Company.  The
Company  and the  Executive  acknowledge  that  the  Executive  will be privy to
confidential  information  of  the  Company  and  its  parent,   subsidiary  and
affiliated  companies  and their  customers  and,  therefore,  if the  Executive
competes  with the Company,  the Company would suffer a  considerable  financial
loss in that  among  other  things it would lose the value of some or all of its
good will.

      In  consideration  of employment  with the Company under the terms of this
Agreement,  the Executive  agrees that during the Term of Employment and for one
(1) year thereafter,  neither the Executive nor any corporation,  partnership or
other entity controlled by, under common control with, or presently  controlling
the Executive  will (i) in the  northeast,  travel,  canvas or advertise for, or
otherwise assist, render services to, become employed by, be a consultant to, or
invest  in any  business  entity  or with any  individual  engage  in, or engage
directly  or  indirectly  in,  any  line or  lines  of  business  carried  on or
contemplated  which,  directly or indirectly,  is a competitor of the Company or
its parent,  subsidiary  and  affiliated  companies,  (ii)  solicit  business or
otherwise  deal  directly or  indirectly  with any customers or persons who were
employees of customers or vendors of the Company at any time,  (iii) directly or
indirectly  divert  or  attempt  to  divert  from  the  Company  or its  parent,
subsidiary and affiliated  companies,  any business in which it has been engaged
during the term of the Executive's  employment with the Company,  or in which it
might  reasonably  be expected to become  engaged,  (iv)  directly or indirectly
interfere or attempt to interfere  with the  relationships  between the Company,
its customers, employees of customers or vendors, and (v) directly or indirectly
interfere or attempt to interfere with the relationship of  employer-employee or
principal and agent of any person  bearing such  relationship  to the Company or
its parent,  subsidiary  and  affiliated  companies,  nor directly or indirectly
divert or attempt to divert any such person from employment or representation of
the  Company or its  parent,  subsidiary  and  affiliated  companies;  provided,
however,  that  the  Executive  shall  not be  prohibited  by the  terms of this
paragraph  from  investing  in and owning not more than one percent  (1%) of the
outstanding  shares of common stock of any corporation,  the shares of which are
publicly  traded  pursuant  to  the  Securities  Exchange  Act of  1934,  and/or
passively invest as a limited partner in any non-publicly traded security.

      (b)   The Executive agrees to promptly notify the


<PAGE>



Company if the Executive  receives any offer of employment  that involves or may
involve any activity  described in Section 10(a) hereof if the employment  might
commence  during or within one (1) year after the termination of the Executive's
employment with the Company. Such notice shall be in writing and shall contain a
complete  description  of the terms of the offer,  including  the  position  and
compensation  offered.  After the  Executive  has so notified the  Company,  the
Executive  agrees that the Company  may inform  such  potential  employer of the
existence of this  Agreement,  including the  provisions of this Section 10, and
once the  Executive  has  indicated  that he  intends to accept the offer if the
Company so permits, the Company shall have ten (10) days to elect:

          (i)  To  convince  the  Executive  to stay at the same or a  different
               salary, compensation, or terms; or

          (ii) To release the  Executive  from any of the  restrictions  in this
               Section 10, but only with  respect to the  particular  employment
               position offered to the Executive; or

          (iii)To insist  upon full  compliance  with the  restrictions  in this
               Section 10.


      (c) The Executive agrees that damages cannot compensate the Company in the
event of a breach or  violation of this  Section  and,  injunctive  relief being
essential for the protection of the Company and its  successors and assigns,  in
addition to other applicable remedies, Company may obtain such injunctive relief
in the event of any such breach or violation  and may assert any other  remedies
it may have at law or in equity.

      (d) The Executive has carefully read and considered the provisions of this
Section 10 and agrees  that the  restrictions  are fair and  reasonable  and are
reasonably  required for the  protection  of the  interests of the Company.  The
Executive understands that the restrictions  contained in this Section may limit
his  ability to engage in a  business  similar to the  Company's  business,  but
acknowledges  that he will  receive  sufficiently  high  remuneration  and other
benefits from the Company hereunder to justify such restrictions.

11.   Miscellaneous.

      (a)  Withholding  Taxes.  The Company  shall  withhold  from all  payments
hereunder  all  applicable  taxes which it is  required  to withhold  therefrom,
unless the Executive has  otherwise  paid such taxes or made other  arrangements
satisfactory to the Company.


<PAGE>



      (b)  Notices.  Any  notice  or other  communication  provided  for in this
Agreement  shall be in writing and  delivered by mail or by hand, in the case of

Executive,  to the address as it appears in the first paragraph  hereof, or such
other address as the Executive may provide to the Company.



      (C) Waiver. This Agreement may not be modified,  altered or amended except
by a written  instrument signed by the parties.  Any waiver or any breach of any
provision  hereof,  or of any  right  or  power  by  any  party  on one or  more
occasions,  shall not be  construed as a waiver of, or a bar to, the exercise of
such  right or power on any  other  occasion  or as a waiver  of any  subsequent
breach.

      (d)  Severability.  The  unenforceability  or  invalidity of any provision
hereof  shall in no way  affect  the  enforceability  or  validity  of any other
provision.

      (e) Binding Effect; Successors.  This Agreement shall inure to the benefit
of and shall be binding upon the Company and its  successors and assigns and the
Executive and the Executive's heirs. The Executive may not assign,  transfer, or
otherwise  dispose of this Agreement,  or any of the parties' rights  hereunder,
without prior written consent of the Company, and any such attempted assignment,
transfer or other disposition without such consent shall be null and void.

      (f) Entire  Agreement.  This Agreement  constitutes  the entire  agreement
between the parties and supersedes any prior or contemporaneous  agreement among
the  parties  with  respect  to the  terms  and  conditions  of the  Executive's
employment.

and enforced in accordance with, the laws of the State of New York applicable to

equivalents  hereunder (subject to the mandatory deferral provided herein),  and

to 100% of the Participants' Compensation.

6.    CASH EQUIVALENT ACCOUNT, INTEREST

      (a)  Deferral  amounts  elected to be  deferred  into the Cash  Equivalent
Account shall be accrued by KeySpan  Energy to a  bookkeeping  account as of the
date  payment  of such  amounts  would  have been made by the  Corporation.  The

and shall not represent  amounts held in trust or a segregation of the assets of
the  Corporation  or any form of  funding  of the  deferred  compensation.  Each
Participant shall receive periodic reports setting forth the amounts credited to
his or her Cash Equivalent

Equivalent Account.

7.    PRIOR DEFERRED PLANS

      Each Participant who was a participant in a Prior Deferred Plan shall have
an allocation made to the Participant's  Stock Equivalent Account of a number of
stock units of KeySpan  Energy stock  determined as if such  Participant  were a
shareholder  of either  the Long  Island  Lighting  Company  or  KeySpan  Energy
Corporation,  as the case may be, on May 28, 1998 with  respect to the number of
stock  equivalents  credited in such Prior Deferred  Plans.  Any amounts of cash
equivalents with respect to a Participant held in a Prior Deferred Plan shall be
allocated to the Cash Equivalent  Account of the Participant  under this Plan as
of the Effective Date.

8.    TRANSFER BETWEEN CASH EQUIVALENT ACCOUNT AND STOCK EQUIVALENT ACCOUNT

      Prior to the first day of each  calendar  year, a  Participant,  by giving
written  notice to the  Corporation,  may  transfer  all or any  portion  of the
balance in his or her Cash Equivalent  Account into his or her Stock  Equivalent
Account  using the price for the  Corporation's  common stock  determined  under
Section 4(b).

9.    FORM AND TIMING OF PAYMENT

      (a)  No  payments  shall  be  made  to  Participants  hereunder  prior  to
retirement, death or termination of service as a director.

      (b) Upon  retirement,  death or termination of service as a director,  all
stock  equivalents  in  the  Participant's  Stock  Equivalent  Account  will  be
converted to cash based on the closing price of the  Corporation's  common stock
reported  on the New York  Stock  Exchange  Composite  Transactions  on the last
trading day of the month in which the event that  determines  the  Participant's
right to receive payment occurs.

      (c)  Payment of the  amount  determined  under (b)  above,  along with any
balance in the Participant's Cash Equivalent Account shall be made in a lump sum
in cash to the Participant as soon as administratively  feasible after the event
that  determines the  Participant's  right to receive  payment.  If the Director
elects on a form  acceptable  to the  Corporation  no later  than the end of the
calendar year preceding the calendar year in which the event that determines the
Participant's right to receive payment occurs, distribution of the Participant's
account may be deferred for up to but no later than 5 years after said event.

      (d) If  elected  by the end of the  calendar  year prior to the event that

                                 INTRODUCTION

MarketSpan  Corporation d/b/a KeySpan Energy ("Company" or "KeySpan") recognizes
that the success and achievement of corporate  goals is directly  related to the
ability  and  performance  of its  employees.  In this  regard,  the Company has
established an Annual Incentive Compensation and Gainsharing Plan ("Plan") which
provides  incentives for achieving specific  performance  objectives and related
financial and operating goals.

In  the  deregulated  utility  environment,   the  need  and  use  of  incentive
compensation   is  a  logical   progression  to  providing   competitive   total
compensation  in the external  marketplace.  The use of a combined  base pay and
incentive  compensation  philosophy has become the norm in salary administration
programs.

In managing the compensation  programs at KeySpan Energy,  it is recognized that
both base pay and  incentives  are integral  components  in an effective  salary
program. One of our compensation  objectives is to identify methods which can be
used to enhance our  existing  programs to create  better "pay for  performance"
plans.  In this  regard,  the Plan  provides  a  method  to  establish  specific
performance  goals.  The Plan also provides a direct link between team and group
performance  results and corporate  initiatives.  The key operational  goals are
based  upon the  corporate  initiatives  and  specifically  focus  upon  growth,
competitive pricing, customer satisfaction and employee excellence.

award for each participant, and to determine the performance objectives,  amount
and  form  of  all  incentive   awards.   The   Committees   may  delegate  such

Officer who may then  delegate such  responsibility  to any other officer of the
Company.

the payment of incentive  awards,  the  Committees  will have the  discretion to
recommend  to the  Board to  provide  or  eliminate  incentive  awards as deemed

7.    CHANGE OF EMPLOYMENT STATUS DURING THE PLAN YEAR

      a)  Promotions/Demotions

      Awards to each plan participant will be based on the employee's target and

      otherwise  determine,  such an  individual  shall not be  entitled  to any
      portion of an incentive  award. If the termination is due to other reasons
      such as reorganization,  transfer to subsidiary, etc., and the termination

      at the end of the plan  year  depending  upon the  actual  length  of paid
      service during the plan year. In the event of death,  any prorated payment
      shall be made to the  beneficiary as indicated on the  individual's  group
      term life insurance beneficiary card.

      considered as though such individual were a member of the Incumbent Board,
      but  excluding,  for this  purpose,  any  such  individual  whose  initial
      assumption  of  office  occurs  as a result  of an  actual  or  threatened

   e) Approval by the  shareholders of the Company of a complete  liquidation or

9. GENERAL PROVISIONS

   a) The Plan shall not  constitute a contract for the continued  employment of
      any participant by the Company.  The Company  reserves the right to modify
      management and officer compensation and benefits at any time and from time
      to time, as it considers  appropriate and to terminate  employment for any
      reason at any time notwithstanding this Plan.

   b) Cash  payments  made  under  this  Plan   generally  will  be  treated  as
      compensation for the purposes of the Company's  Retirement Plan benefit if
      the employee is:

      1)  Enrolled in the Employee's Retirement Plan of KeySpan Energy,

      2)  Enrolled in the Retirement Income Plan of KeySpan Energy,  with a base
          salary of $75,000 or above.

   Awards will be considered pensionable earnings provided that such payments do
   not result in  disqualification  of the  Retirement  Plan under 401(a) of the
   Internal Revenue Code or adversely affect the exempt status of the Retirement
   Plan  trust  under  Section  501(a)  of  said  code.  Cash  payments  of  any
   non-deferred portion of an incentive award received after retirement or death
   shall be treated for Retirement  Plan benefit  purposes as  compensation  for
   services rendered in the last Retirement Plan year in which the recipient was
   employed,  if the employee was a participant  in an existing  incentive  plan
   prior to 10/1/95.  Cash payments of the portions that were actually  deferred
   or would have normally been deferred which are received  after  retirement or
   death  will  not be  considered  compensation  for  Retirement  Plan  benefit
   purposes.

      alienated, or transferred by any participant under the Plan, or be subject
      to attachment, garnishment or other legal process.

   d) Except as  addressed  herein,  incentive  compensation  payments  will not
      affect the level of  benefits  under any other  employee  benefit  plan or
      program of the Company.

      deferral or after tax  contribution  election made by the employee subject
      to the limitations established in the current 401(k) plan.

   f) The Board of Directors of the Company may change,  modify or terminate the
      Plan in whole or in part, either in general or in particular cases, at any
      time with or without notice.

Exhibit 10.20

                                 KEYSPAN ENERGY
                SENIOR EXECUTIVE CHANGE OF CONTROL SEVERANCE PLAN

                                  INTRODUCTION

           The Board of Directors of MarketSpan Corporation d/b/a KeySpan Energy
recognizes  that,  as is the case with many publicly  held  corporations,  there
exists  the  possibility  of a  Change  of  Control.  This  possibility  and the
uncertainty  it  creates  may  result  in the  loss  or  distraction  of  senior
executives of the Company, to the detriment of the Company and its shareholders.

           The Board  considers the avoidance of such loss and distraction to be
essential to protecting  and enhancing the best interests of the Company and its
shareholders. The Board also believes that when a Change of Control is perceived
as imminent,  or is  occurring,  the Board should be able to receive and rely on
disinterested service from senior executives regarding the best interests of the
Company and its  shareholders,  without concern that senior  executives might be
distracted or concerned by the personal  uncertainties  and risks created by the
perception of an imminent or occurring Change of Control.

           In  addition,  the  Board  believes  that it is  consistent  with the
Company's  employment  practices  and policies and in the best  interests of the
Company and its  shareholders  to treat fairly its  employees  whose  employment
terminates in connection with or following a Change of Control.

           Accordingly,  the Board has determined that appropriate  steps should
be taken to assure the Company of the  continued  employment  and  attention and
dedication  to  duty  of  its  senior  executives  and to  seek  to  ensure  the
availability of their continued service, notwithstanding the possibility, threat
or occurrence of a Change of Control.

           Therefore, in order to fulfill the above purposes, the following plan
has been developed and is hereby adopted, as of October 30, 1998.

                                   ARTICLE I
                              ESTABLISHMENT OF PLAN

     As of the  Effective  Date,  the Company  hereby  establishes  a separation
compensation plan known as the KeySpan Energy Senior Executive Change of Control
Severance Plan, as set forth in this document.

                                   ARTICLE II
                                  DEFINITIONS

           As used  herein,  the  following  words and  phrases  shall  have the
following  respective  meanings unless the context clearly indicates  otherwise.

     (a) ANNUAL  BONUS  AWARD.  The annual  cash  bonus  that a  Participant  is
eligible to earn  pursuant to the 1998  Corporate  Incentive  Compensation  Plan
and/or any successor thereto.

          (b) ANNUAL SALARY.  The  Participant's  regular annual base
salary  immediately  prior to his or her  termination of  employment,  including
compensation  converted  to other  benefits  under a  flexible  pay  arrangement
maintained  by the Company or deferred  pursuant to a written  plan or agreement
with the Company. 

          (c) BOARD.  The Board of Directors of the Parent.  

     (d) CAUSE.  With respect to any Participant:  (i) the willful and continued
failure of the Participant to perform  substantially  the  Participant's  duties
with the Company or one of its affiliates (other than any such failure resulting
from incapacity due to physical or mental  illness),  after a written demand for
substantial  performance  is  delivered to the  Participant  by the Board or the
Chief Executive Officer of the Parent which  specifically  identifies the manner
in which the Board or Chief Executive  Officer believes that the Participant has
not  substantially  performed  the  Participant's  duties,  or (ii) the  willful
engaging by the  Participant  in illegal  conduct or gross  misconduct  which is
materially  and  demonstrably  injurious  to the  Company.  For purposes of this
definition,  no act or  failure to act on the part of the  Participant  shall be
considered  "willful"  unless  it is  done,  or  omitted  to  be  done,  by  the
Participant  in bad faith or without  reasonable  belief that the  Participant's
action or omission was in the best interests of the Company.  Any act or failure
to act based upon authority  given pursuant to a resolution  duly adopted by the
Board  or upon the  instructions  of the  Chief  Executive  Officer  or a senior
officer of the Parent or based upon the advice of counsel for the Company  shall
be  conclusively  presumed to be done, or omitted to be done, by the Participant
in good faith and in the best  interests of the Company.

following the Effective Date:

of Section  13(d)(3) or  14(d)(2) of the  Securities  Exchange  Act of 1934,  as

meaning  of Rule 13d-3  promulgated  under the  Exchange  Act) of 20% or more of
either  (x) the then  outstanding  shares of  common  stock of the  Parent  (the
"Outstanding  Common  Stock")  or (y) the  combined  voting  power  of the  then
outstanding  voting  securities of the Parent  entitled to vote generally in the
election of directors (the "Outstanding Voting Securities");  provided, however,
that for purposes of this subsection (i), the following  acquisitions  shall not
constitute a Change of Control:  (A) any  acquisition  directly from the Parent,

plan (or related trust) sponsored or maintained by the Parent or any corporation
controlled by the Parent or (D) any acquisition by any corporation pursuant to a

the Effective  Date whose  election,  or nomination for election by the Parent's
shareholders,  was  approved by a vote of at least a majority  of the  directors
then  comprising  the  Incumbent  Board  shall  be  considered  as  though  such
individual  were a  member  of the  Incumbent  Board,  but  excluding,  for this
purpose,  any such  individual  whose  initial  assumption of office occurs as a
result of an actual or threatened  election contest with respect to the election
or removal of directors or other actual or threatened solicitation of proxies or
consents by or on behalf of a Person other than the Board; or

     (iii) Consummation of a reorganization,  merger or consolidation or sale or
other disposition of all or substantially all of the assets of the Parent or the
acquisition of assets of another corporation (a "Business Combination"), in each
case, unless, following such Business Combination,  (A) all or substantially all
of the individuals and entities who were the beneficial owners, respectively, of
the Outstanding Common Stock and Outstanding Voting Securities immediately prior
to such Business Combination beneficially own, directly or indirectly, more than
60% of,  respectively,  the then  outstanding  shares  of  common  stock and the
combined voting power of the then outstanding voting securities entitled to vote
generally in the election of directors,  as the case may be, of the  corporation
resulting from such Business  Combination in substantially  the same proportions
as their  ownership,  immediately  prior  to such  Business  Combination  of the
Outstanding Common Stock and Outstanding Voting Securities,  as the case may be,
(B) no Person  (excluding  the Parent,  any  employee  benefit  plan (or related
trust)  of  the  Parent  or  such  corporation   resulting  from  such  Business
Combination)  beneficially  owns,  directly  or  indirectly,  20%  or  more  of,

                               SEPARATION BENEFITS

     4.1 TERMINATIONS OF EMPLOYMENT WHICH GIVE RISE TO SEPARATION BENEFITS UNDER
PLAN. A  Participant  shall be entitled to  Separation  Benefits as set forth in
Section  4.2 below if, at any time before the third  anniversary  of the Date of
the Change of Control,  the  Participant's  Employment is terminated  (i) by the
Company for any reason other than Cause, death, Disability or Retirement or (ii)
by the Participant  after the occurrence of Good Reason and on or before 90 days
after the occurrence of Good Reason.

     4.2 SEPARATION BENEFITS.

     (a)  If  a  Participant's  employment  is  terminated  under  circumstances
entitling  him or her to  Separation  Benefits as provided in Section  4.1,  the
Company shall pay such Participant,  within ten days of the Date of Termination,
a cash lump sum as set forth in subsection (b) below and the continued  benefits
set forth in subsection (c) below.  For purposes of determining the benefits set
forth  in  subsection  (b) and  (c),  if the  termination  of the  Participant's
employment  is  for  Good  Reason  after  there  has  been  a  reduction  of the
Participant's  Annual  Salary,  opportunity  to earn  Annual  Bonuses,  or other
compensation or employee benefits, such reduction shall be ignored.

     (b) The cash lump sum referred to in Section 4.2(a) is the aggregate of the
following amounts:

     (i) the sum of (1) the  Participant's  Annual  Salary  through  the Date of
Termination  to the  extent not  theretofore  paid,  (2) the  product of (x) the
Highest Annual Bonus and (y) a fraction, the numerator of which is the number of
days in such year through the Date of Termination,  and the denominator of which
is  365,  and  (3)  any  compensation  previously  deferred  by the  Participant
(together  with any  accrued  interest  or  earnings  thereon)  and any  accrued
vacation  pay,  in each  case to the  extent  not  theretofore  paid and in full
satisfaction of the rights of the Participant thereto;

     (ii) an amount equal to the product of (1) the Participant's Multiple times
(2) the sum of the Participant's (x) Annual Salary and (y) Highest Annual Bonus;
and

     (iii)  an  amount  equal  to  the  difference  between  (a)  the  actuarial
equivalent  of  the  benefit  under  the  Company's  qualified  defined  benefit
retirement  plan  (the  "Retirement   Plan")  and  any  excess  or  supplemental
retirement  plans in  which  the  Participant  participates  (collectively,  the
"SERP") which the Participant  would receive if his or her employment  continued
during the  Separation  Period,  assuming  that the  Participant's  compensation
during the Separation Period would have been equal to his or her compensation as
in effect  immediately  before the termination  or, if higher,  on the Effective
Date, and (b) the actuarial equivalent of the Participant's actual benefit (paid
or payable),  if any, under the  Retirement  Plan and the SERP as of the Date of
Termination.   The  actuarial  assumptions  used  for  purposes  of  determining
actuarial  equivalence  shall be no less favorable to the  Participant  than the
most favorable of those in effect under the Retirement  Plan and the SERP on the
Date of Termination and the Effective Date.

     (c) The continued benefits referred to above are as follows:

     (i) during the Separation  Period,  the  Participant  and his or her family
shall be provided with  medical,  dental and life  insurance  benefits as if the
Participant's employment had not been terminated; provided, however, that if the
Participant  becomes reemployed with another employer and is eligible to receive
medical or other welfare  benefits  under another  employer-provided  plan,  the
medical and other welfare benefits  described herein shall be secondary to those
provided under such other plan during such applicable period of eligibility. For
purposes  of  determining  eligibility  (but  not the  time of  commencement  of
benefits) of the  Participant  for retiree  medical,  dental and life  insurance
benefits  under the  Company's  plans,  practices,  programs and  policies,  the
Participant  shall be considered to have remained employed during the Separation
Period and to have retired on the last day of such period; and

     (ii) the  Company  shall,  at its sole  expense as  incurred,  provide  the
Participant with outplacement  services the scope and provider of which shall be
selected by the  Participant in his or her sole discretion (but at a cost to the
Company of not more than $30,000);

To the extent any benefits  described in this Section  4.2(c) cannot be provided
pursuant  to the  appropriate  plan or program  maintained  for  Employees,  the
Company  shall  provide  such  benefits  outside  such  plan  or  program  at no
additional cost (including without limitation tax cost) to the Participant. 

     4.3  OTHER  BENEFITS  PAYABLE.  The cash lump sum and  continuing  benefits
described  in Section 4.2 above shall be payable in addition to, and not in lieu
of, all other  accrued or vested or earned but  deferred  compensation,  rights,
options or other benefits  which may be owed to a Participant  upon or following
termination,  including but not limited to accrued vacation or sick pay, amounts
or benefits payable under any bonus or other  compensation  plans,  stock option
plan,  stock  ownership plan,  stock purchase plan, life insurance plan,  health
plan,  disability plan or similar or successor plan, but excluding any severance
pay or pay in lieu of  notice  required  to be  paid to such  Participant  under
applicable law.

     4.4 CERTAIN ADDITIONAL PAYMENTS BY THE COMPANY.

     (a) Anything in this Plan to the contrary notwithstanding and except as set
forth  below,  in  the  event  it  shall  be  determined  that  any  payment  or
distribution  by the Company to or for the benefit of any  Participant  (whether
paid or payable or  distributed or  distributable  pursuant to the terms of this
Plan or otherwise,  but determined  without  regard to any  additional  payments
required  under this Section 4.4) (a  "Payment")  would be subject to the excise
tax  imposed  by  Section  4999 of the Code or any  interest  or  penalties  are
incurred by the  Participant  with  respect to such excise tax (such excise tax,
together  with any such interest and  penalties,  are  hereinafter  collectively
referred  to as the "Excise  Tax"),  then the  Participant  shall be entitled to
receive an  additional  payment (a  "Gross-Up  Payment")  in an amount such that
after  payment  by the  Participant  of all taxes  (including  any  interest  or
penalties imposed with respect to such taxes),  including,  without  limitation,
any income taxes (and any interest and penalties  imposed with respect  thereto)
and Excise Tax imposed upon the Gross-Up  Payment,  the  Participant  retains an
amount  of the  Gross-Up  Payment  equal  to the  Excise  Tax  imposed  upon the
Payments.

     (b)  Subject  to the  provisions  of  Section  4.4(c),  all  determinations
required  to be made  under  this  Section  4.4,  including  whether  and when a
Gross-Up  Payment is required  and the amount of such  Gross-Up  Payment and the
assumptions to be utilized in arriving at such  determination,  shall be made by
Arthur  Andersen LLP or such other  certified  public  accounting firm as may be
designated  by the  Participant  (the  "Accounting  Firm"),  which shall provide
detailed supporting  calculations both to the Company and the Participant within
15 business  days of the receipt of notice from the  Participant  that there has
been a Payment,  or such earlier  time as is  requested  by the Company.  In the
event  that the  Accounting  Firm is serving as  accountant  or auditor  for the
individual,  entity or group  effecting the Change of Control,  the  Participant
shall  appoint  another  nationally  recognized  accounting  firm  to  make  the
determinations  required hereunder (which accounting firm shall then be referred
to as the Accounting  Firm  hereunder).  All fees and expenses of the Accounting
Firm shall be borne solely by the Company.  Any Gross-Up Payment,  as determined
pursuant to this  Section  4.4 shall be paid by the  Company to the  Participant
within  five days of the receipt of the  Accounting  Firm's  determination.  Any
determination  by the Accounting  Firm shall be binding upon the Company and the
Participant.  As a result of the  uncertainty in the application of Section 4999
of the Code at the time of the  initial  determination  by the  Accounting  Firm
hereunder,  it is possible that Gross-Up  Payments which will not have been made
by the  Company  should  have been made  ("Underpayment"),  consistent  with the
calculations  required  to be made  hereunder.  In the  event  that the  Company
exhausts its remedies pursuant to Section 4.4(c) and the Participant  thereafter
is  required  to make a payment of any Excise  Tax,  the  Accounting  Firm shall
determine  the  amount  of the  Underpayment  that  has  occurred  and any  such
Underpayment  shall be promptly paid by the Company to or for the benefit of the
Participant.

     (c) The Participant shall notify the Company in writing of any claim by the
Internal  Revenue Service that, if successful,  would require the payment by the
Company of the Gross-Up  Payment.  Such  notification  shall be given as soon as
practicable  but no later  than ten  business  days  after  the  Participant  is
informed in writing of such claim and shall apprise the Company of the nature of
such  claim  and the  date on which  such  claim is  requested  to be paid.  The
Participant  shall not pay such  claim  prior to the  expiration  of the  30-day
period  following the date on which it gives such notice to the Company (or such
shorter period ending on the date that any payment of taxes with respect to such
claim is due). If the Company  notifies the  Participant in writing prior to the
expiration of such period that it desires to contest such claim, the Participant
shall:

     (i) give the Company any  information  reasonably  requested by the Company
relating to such claim;

     (ii) take such  action in  connection  with  contesting  such  claim as the
Company  shall  reasonably  request  in  writing  from time to time,  including,
without limitation, accepting legal representation with respect to such claim by
an attorney reasonably selected by the Company;

     (iii)  cooperate  with the  Company in good faith in order  effectively  to
contest such claim; and

     (iv) permit the Company to participate in any proceedings  relating to such
claim, provided, however, that the Company shall bear and pay directly all costs
and  expenses   (including   additional  interest  and  penalties)  incurred  in
connection  with such  contest  and  shall  indemnify  and hold the  Participant
harmless,  on an after-tax  basis,  for any Excise Tax or income tax  (including
interest  and  penalties  with  respect  thereto)  imposed  as a result  of such
representation  and payment of costs and  expenses.  Without  limitation  on the
foregoing  provisions  of this Section  4.4(c),  the Company  shall  control all
proceedings  taken in connection with such contest and, at its sole option,  may
pursue or forgo any and all administrative  appeals,  proceedings,  hearings and
conferences  with the taxing  authority in respect of such claim and may, at its
sole option,  either direct the Participant to pay the tax claimed and sue for a
refund or  contest  the claim in any  permissible  manner,  and the  Participant
agrees to prosecute such contest to a  determination  before any  administrative
tribunal,  in a court  of  initial  jurisdiction  and in one or  more  appellate
courts, as the Company shall determine;  provided,  however, that if the Company
directs  the  Participant  to pay such claim and sue for a refund,  the  Company
shall advance the amount of such payment to the Participant, on an interest-free
basis and shall  indemnify and hold the  Participant  harmless,  on an after-tax
basis,  from any Excise Tax or income tax (including  interest or penalties with
respect  thereto)  imposed  with  respect to such advance or with respect to any
imputed  income with  respect to such  advance;  and further  provided  that any
extension  of the  statute of  limitations  relating to payment of taxes for the
taxable year of the Participant  with respect to which such contested  amount is
claimed to be due is limited solely to such contested amount.  Furthermore,  the
Company's  control of the  contest  shall be limited to issues  with  respect to
which a Gross-Up Payment would be payable hereunder and the Participant shall be
entitled to settle or contest, as the case may be, any other issue raised by the
Internal Revenue Service or any other taxing authority.

     (d) If, after the receipt by the  Participant of an amount  advanced by the
Company pursuant to Section 4.4(c), the Participant  becomes entitled to receive
any refund with respect to such claim,  the  Participant  shall  (subject to the
Company's complying with the requirements of Section 4.4(c)) promptly pay to the
Company the amount of such refund  (together  with any interest paid or credited
thereon  after  taxes  applicable  thereto).   If,  after  the  receipt  by  the
Participant of an amount advanced by the Company  pursuant to Section 4.4(c),  a
determination  is made that the Participant  shall not be entitled to any refund
with  respect to such claim and the Company does not notify the  Participant  in
writing of its intent to contest such denial of refund  prior to the  expiration
of 30 days after such  determination,  then such  advance  shall be forgiven and
shall not be required to be repaid and the amount of such advance  shall offset,
to the extent thereof, the amount of Gross-Up Payment required to be paid.

     4.5 PAYMENT  OBLIGATIONS  ABSOLUTE.  Except as provided in Section 4.6, the
obligations of the Company to pay the separation  benefits  described in Section
4.2 and any additional  payments  described in Section 4.4 shall be absolute and
unconditional and shall not be affected by any circumstances, including, without
limitation, any set-off, counterclaim,  recoupment, defense or other right which
the Company may have against any Participant. In no event shall a Participant be
obligated to seek other employment or take any other action by way of mitigation
of the amounts  payable to a  Participant  under any of the  provisions  of this
Plan,  nor  shall  the  amount  of  any  payment  hereunder  be  reduced  by any
compensation  earned by a  Participant  as a result  of  employment  by  another
employer, except as specifically provided in Section 4.2 (c) (i).

     4.6  PAYMENT  OBLIGATIONS  UNDER  PRIOR  AGREEMENTS.  If a  Participant  is
entitled to receive any benefits or payments under any agreement or plan between
or binding the Company or any  predecessor  thereof  with respect to a change of
control that  occurred  prior to the  Effective  Date,  and the  Participant  is
entitled to receive the  Separation  Benefits  described  in Section 4.2 and any
additional  payments  described  in Section 4.4,  the  Participant  may elect to
receive the benefits and payments  provided  pursuant to such prior agreement or
plan rather than the  benefits and  payments  provided  pursuant to this Plan by
providing  notice of such  election to the  Company  within five (5) days of the
Date of Termination.  Any such election shall  constitute a waiver of all rights
to receive benefits hereunder.


                                  ARTICLE V
                              SUCCESSOR TO COMPANY

           This Plan shall bind any successor of the Company,  its assets or its
businesses (whether direct or indirect,  by purchase,  merger,  consolidation or
otherwise),  in the same manner and to the same extent that the Company would be
obligated under this Plan if no succession had taken place.

           In the case of any  transaction in which a successor would not by the
foregoing  provision or by  operation of law be bound by this Plan,  the Company
shall require such successor  expressly and  unconditionally to assume and agree
to perform the Company's  obligations under this Plan, in the same manner and to
the same  extent  that the  Company  would be  required  to  perform  if no such
succession had taken place. The term "Company," as used in this Plan, shall mean
the  Company as  hereinbefore  defined  and any  successor  or  assignee  to the
business or assets which by reason hereof becomes bound by this Plan.

                                   ARTICLE VI
                       DURATION, AMENDMENT AND TERMINATION

6.1 DURATION.  If a Change of Control has not  occurred,  this Plan shall expire
five years from the Effective Date,  unless extended for an additional period or
periods by action of the Board. If a Change of Control occurs while this Plan is
in  effect,  this Plan  shall  continue  in full  force and effect and shall not
terminate  or expire  until after all  Participants  who become  entitled to any
payments hereunder shall have received such payments in full and all adjustments
required to be made  pursuant to Section 4.4 have been made. 

     6.2 AMENDMENT OR TERMINATION. The Board may amend or terminate this Plan at
any  time;  provided,  that  this  Plan may not be  terminated  or  amended  (i)
following  a Change of  Control,  (ii) at the  request of a third  party who has
taken  steps  reasonably  calculated  to  effect a Change of  Control,  or (iii)
otherwise in connection with or in anticipation of a Change of Control,  in each
case, in any manner that could  adversely  affect the rights of any  Participant
without such Participant's express written consent.

6.3 PROCEDURE FOR EXTENSION,  AMENDMENT OR TERMINATION.
Any extension,  amendment or termination of this Plan by the Board in accordance
with the foregoing  shall be made by action of the Board in accordance  with the
Parent's  charter and by-laws and  applicable  law,  and shall be evidenced by a
written instrument signed by a duly authorized officer of the Parent, certifying
that the Board has taken such action.

                                  ARTICLE VII
                                  MISCELLANEOUS

     7.1  INDEMNIFICATION.  If a  Participant  institutes  any  legal  action in
seeking to obtain or enforce,  or is required to defend in any legal  action the
validity or  enforceability  of, any right or benefit provided by this Plan, the
Company will pay for all actual legal fees and expenses  incurred (as  incurred)
by such Participant, regardless of the outcome of such action.

     7.2  EMPLOYMENT  STATUS.  This  Plan  does not  constitute  a  contract  of
employment,  nor does it impose on the Participant or the Company any obligation
for  the  Participant  to  remain  an  Employee  or  change  the  status  of the
Participant's  employment or the Company's  policies  regarding  termination  of
employment.

     7.3 NAMED FIDUCIARY;  ADMINISTRATION. The Company is the named fiduciary of
the  Plan,  with  full  authority  to  control  and  manage  the  operation  and
administration of the Plan, acting through the Human Resources Division.

     7.4 CLAIM  PROCEDURE.  If an  Employee or former  Employee  makes a written
request alleging a right to receive benefits under this Plan or alleging a right
to receive an  adjustment  in  benefits  being paid under the Plan,  the Company
shall treat it as a claim for  benefit.  All claims for  benefit  under the Plan
shall  be sent to the  Human  Resources  Division  of the  Company  and  must be
received  within  30  days  after  termination  of  employment.  If the  Company
determines that any individual who has claimed a right to receive  benefits,  or
different benefits, under the Plan is not entitled to receive all or any part of
the  benefits   claimed,   it  will  inform  the  claimant  in  writing  of  its
determination  and the reasons  therefor in terms calculated to be understood by
the  claimant.  The notice will be sent  within 90 days of the claim  unless the
Company determines additional time, not exceeding 90 days, is needed. The notice
shall make  specific  reference to the  pertinent  Plan  provisions on which the
denial  is based,  and  describe  any  additional  material  or  information  is
necessary.  Such notice shall,  in addition,  inform the claimant what procedure
the claimant should follow to take advantage of the review  procedures set forth
below in the event the claimant  desires to contest the denial of the claim. The
claimant may within 90 days thereafter submit in writing to the Company a notice
that the  claimant  contests  the denial of his or her claim by the  Company and
desires a further review. The Company shall within 60 days thereafter review the
claim and  authorize  the  claimant to appear  personally  and review  pertinent
documents  and submit  issues and comments  relating to the claim to the persons
responsible for making the  determination on behalf of the Company.  The Company
will render its final  decision  with specific  reasons  therefor in writing and
will  transmit  it to the  claimant  within 60 days of the  written  request for
review, unless the Company determines additional time, not exceeding 60 days, is
needed,  and so notifies the  Participant.  If the Company fails to respond to a
claim filed in accordance with the foregoing within 60 days or any such extended
period, the Company shall be deemed to have denied the claim.

     7.5 ARBITRATION. Any dispute or controversy arising out of or in connection
with this Plan or any alleged breach hereof which is not settled pursuant to the
provisions of Section 7.4, shall be settled by arbitration in New York, New York
pursuant  to the  rules  of the  American  Arbitration  Association.  If the two
parties cannot jointly select a single  arbitrator to determine the matter,  one
arbitrator shall be chosen by the American Arbitration  Association on behalf of
such parties.  The decision of the single  arbitrator  will be final and binding
upon the parties and the  judgment of a court of competent  jurisdiction  may be
entered thereon.  Fees of the arbitrator and costs of arbitration shall be borne
by the parties in such manner as shall be determined by the arbitrator.

     7.6  UNFUNDED  PLAN  STATUS.  This Plan is intended to be an unfunded  plan
maintained  primarily for the purpose of providing  deferred  compensation for a
select group of management or highly compensated  employees,  within the meaning
of Section 401 of ERISA.  All  payments  pursuant to the Plan shall be made from
the  general  funds of the  Company  and no  special or  separate  fund shall be
established  or  other  segregation  of  assets  made  to  assure  payment.   No
Participant or other person shall have under any  circumstances  any interest in
any particular property or assets of the Company as a result of participating in
the Plan.  Notwithstanding  the  foregoing,  the  Company  may (but shall not be
obligated to) create one or more grantor trusts, the assets of which are subject
to the claims of the Company's creditors,  to assist it in accumulating funds to
pay its obligations under the Plan.

     7.7 VALIDITY AND SEVERABILITY.  The invalidity or  unenforceability  of any
provision  of the Plan shall not affect the  validity or  enforceability  of any
other  provision of the Plan,  which shall remain in full force and effect,  and
any prohibition or  unenforceability in any jurisdiction shall not invalidate or
render unenforceable such provision in any other jurisdiction.

     7.8  GOVERNING  LAW.  The  validity,   interpretation,   construction   and
performance  of the Plan shall in all  respects  be  governed by the laws of New
York,  without  reference to principles of conflict of law, except to the extent
preempted by ERISA.

Exhibit 10.21

                                 AMENDMENT TO
                             EMPLOYMENT AGREEMENT

      THIS AMENDMENT TO EMPLOYMENT AGREEMENT ("Amendment"), effective as
of the 30th day of October,  1998,  is entered  into by and between The Brooklyn
Union  Gas  Company,  a New York  Corporation,  KeySpan  Energy  Corporation,  a
Delaware  corporation,  MarketSpan  Corporation,  a New York  Corporation  doing
business as KeySpan  Energy,  hereinafter  referred to either by company name or
collectively as the "Company" and David L. Phillips,  hereinafter referred to as
"Employee."

      WHEREAS,  Employee  and The Brooklyn  Union Gas Company  entered into that
certain  EMPLOYMENT  AGREEMENT  (the  "Agreement")  effective  January  1, 1997,
expressly  providing  for the term  employment of Employee by the Company in the
capacity of Senior Vice President, Strategic Planning & Corporate Development.

      WHEREAS,  Article III(d) of the Agreement provides that Employee shall not
be eligible to  participate  in The Brooklyn  Union Senior  Executive  Change of
Control  Severance  Plan (the "BU  Plan"),  and  Article  V(a) of the  Agreement
provides that, notwithstanding anything contained in the BU Plan, Employee shall
be entitled to specific benefits set forth in the Agreement; and

      WHEREAS,  on October 30, 1998,  the Board of  Directors of KeySpan  Energy
adopted a KeySpan  Energy  Senior  Executive  Change of Control  Severance  Plan
("KeySpan Plan").

      NOW THEREFORE,  as additional  incentive to Employee in consideration  for
rendering  services  to  the  Company  and  in  order  to  provide  similar  and
appropriate  separation  benefits to Employee as are currently provided to other
senior  executives of the Company in similar  positions,  and for other good and
valuable  consideration  the  receipt  and  sufficiency  of  which  are  hereby,
acknowledged by the Company, the undersigned hereby agrees as follows:

      1. (a) Article  III(d) of the  Agreement and Article V(a) of the Agreement
are hereby  amended to provide that Employee shall be entitled to the separation
benefits and all other benefits set forth in the KeySpan Plan.

            (b)  Employee  and the Company  acknowledge  and agree that,  in the
event of a change of  control  (as such term is defined  in the  KeySpan  Plan),
Employee  shall be entitled to all  separation  benefits in accordance  with the
KeySpan Plan and that such  benefits  shall be in lieu of and not in addition to
the benefits set forth in Article V of the Agreement  and that,  notwithstanding
anything to the  contrary in the  Agreement,  the change of control  provisions,
provisions  relating to Gross-Up  Payments (as defined in the KeySpan  Plan) and
all other  provisions of the KeySpan Plan shall apply when  inconsistent  or not
addressed in the Agreement.

            (c) In accordance  with Section 3.1 of the KeySpan Plan, the Company
hereby agrees that  Schedule I of the KeySpan Plan shall  designate the Employee
as a  Participant  (as defined in the KeySpan Plan) and, for the purposes of the
KeySpan Plan,  the Multiple (as defined in the KeySpan Plan) for Employee  shall
be equal to the Multiple set forth on Schedule I of the Key Span
