Cautionary Language Concerning Forward-Looking Statements
- ---------------------------------------------------------

     Certain statements contained herein are forward-looking  statements,  which
reflect  numerous  assumptions  and  estimates and involve a number of risks and
uncertainties.  For these statements, we claim the protection of the safe harbor
for  forward-looking  statements  provided by the Private Securities  Litigation

     There are  possible  developments  that could  cause our actual  results to

events or otherwise.

     Among the factors that could cause actual results to differ materially are:
general  economic  conditions,   especially  in  the  Northeast  United  States;
available sources and cost of fuel; volatility of energy prices in a deregulated
market  environment  as well as in the  source of  natural  gas and fuel used to
generate  electricity;  potential  write-down  of our  investment in natural gas
properties  when  natural  gas prices are  depressed  or if we have  significant
downward  revisions  in our  estimated  proved gas  reserves;  federal and state
regulatory  initiatives that increase competition,  threaten cost and investment
recovery,  and impact rate  structures;  our ability to successfully  reduce our
cost structures; implementation of new accounting standards; the degree to which
the we develop  unregulated  business  ventures;  as well as  federal  and state
regulatory  policies  affecting our ability to retain and operate those business
ventures; our ability to identify and make complementary  acquisitions,  as well
as the successful  integration of those  acquisitions;  inflationary  trends and
interest rates; and risks detailed from time to time in reports filed by us with
the Securities and Exchange Commission.

Item 1.01       Entry into a Material Definitive Agreement
- ---------       ------------------------------------------

     On January  31,  2005  KeySpan  Business  Solutions,  LLC,  a wholly  owned
subsidiary  of the  Company,  entered  into an  agreement  with  certain  former
employees[1], pursuant to which each of the following entities were sold to such
individuals effective as of the date of execution:  Binsky & Snyder, LLC; Binsky
&  Snyder  Services,  LLC;  and  Binsky  & Snyder  Plumbing,  LLC  (the  "Binsky
Companies").  Pursuant to this agreement,  the Company received  proceeds of $10
million,  $5  million  of  which  is to be paid  over a three  year  period.  In
addition,  the  Company  retained  its  previously  incurred  indemnity  support
obligations related to certain surety,  performance and payment bonds issued for
the benefit of those entities prior to closing, the current outstanding value of
which is  approximately  $15 million.  The parties have agreed to cooperate with
the Company to seek a release of the Company's indemnity obligation with respect
to all or a portion of such outstanding bonds after closing.  Any costs incurred
to obtain such release will be borne by the Company.


Item 2.06       Material Impairments
- ---------       --------------------

     As  previously  disclosed  in our  quarterly  report for the  period  ended
September 30, 2004, KeySpan's Board of Directors authorized  management to begin
the process of disposing of a significant  portion of its ownership interests in
certain  companies  within  the Energy  Services  segment -  specifically  those
companies engaged in mechanical contracting activities. Earlier in January 2005,
the Company  completed the  divestiture of three such  entities.[2] At a meeting
held on January  26,  2005,  the Board  reviewed  the  status of the  divestment
program  and  authorized  the sale,  within  certain  parameters,  of the Binsky
Companies and WDF, Inc., (the remaining mechanical  contracting  companies).  In
view of the likely disposition of those companies on such terms, a determination
was made that a material  reduction in the carrying value of our  investments in
all of the mechanical  contracting  companies is required.  Accordingly,  in the
fourth  quarter of 2004,  the  Company  intends  to record a pre-tax  impairment
charge related to its  investment in these  entities in the aggregate  amount of
between  $80 and $90  million.  Included in this amount is an estimate of future
cash  expenditures  of  between  $25 and $35  million  that may be  incurred  in
connection with the disposition of these entities.

     In addition, on January 26, 2005, management determined to proceed with the
disposition of our 50% ownership  interest in Premier  Transmission  Limited,  a
natural gas  transmission  pipeline in Northern  Ireland.  In view of the likely
disposition on the terms currently  contemplated,  a determination was also made
that a material reduction in the carrying value of our investment in this entity
is required.  Accordingly, in the fourth quarter of 2004, the Company intends to
record a pre-tax  impairment  charge related to its investment in this entity in
the aggregate amount of between $25 and $30 million.  Included in this amount is
an estimate of future cash expenditures of up to $5 million that may be incurred
in connection with the disposition.

1    The parties to the agreement were as follows:  Robert B. Snyder,  Robert B.
     Snyder, Jr., Frank J. Sullivan, Philip J. Andreoli and William J. McKean.

2    The entities disposed of were as follows: Granite State Plumbing & Heating,
     LLC; Northern Peabody, LCC; and Delta KeySpan, LLC.
