                                       OF
                               KEYSPAN CORPORATION
                    ANNUAL MEETING TO BE HELD ON MAY 8, 2003

Proxies are being  solicited  on behalf of the Board of Directors of the Company
for use at the Annual Meeting of Shareholders on May 8, 2003, or any adjournment
thereof.  This Proxy Statement is first being mailed to the  shareholders of the
Company on or about March 27, 2003.

Q:   What am I voting on?

A:   Election  of nine  directors;  ratification  of  Deloitte & Touche  LLP, as
     independent  public  accountants  for the year ending  December  31,  2003;
     Approval of  amendments  to the  Employee  Discount  Stock  Purchase  Plan;
     consideration  of a  shareholder  proposal,  if  presented  at  the  Annual
     Meeting; and any other business properly brought before the meeting.

Q:   Who is entitled to vote?

A:   Common  Stock  shareholders  as of the close of  business on March 10, 2003
     (the "Record Date").  Each share of KeySpan's  Common Stock, par value $.01
     per share (the "Common Stock") is entitled to one vote.

Q:   How do I vote?

A:   If you hold your shares in your name, as a "shareholder of record," you can
     vote in person at the Annual Meeting or you can complete and submit a proxy
     by mail, telephone or the Internet, as provided on your proxy card.

     The enclosed  proxy card  contains  instructions  for mail,  telephone  and
     Internet voting.  Whichever  method you use, the proxies  identified on the
     proxy card will vote your shares in accordance with your instructions.

     If you submit a proxy card without giving specific voting instructions with
     respect to any or all  proposals,  you give the named proxies the authority
     to vote,  in their  discretion,  on each  such  proposal.  In  addition,  a
     properly  signed and dated  proxy card (or a proxy  properly  delivered  by
     telephone or through the Internet) gives the named proxies the authority to
     vote,  in their  discretion,  on any  other  matter  that may  arise at the
     meeting.

     If you hold your shares  indirectly in the name of a bank,  broker or other
     nominee, as a "street-name shareholder," you will receive instructions from
     your bank, broker or other nominee describing how to vote your shares.

Q:   Do I have the right to revoke my proxy?

A:   Yes. You can revoke your proxy by  submitting a new proxy;  giving  written
     notice  to the  Corporate  Secretary  of the  Company  prior to the  Annual
     Meeting  stating that you are revoking your proxy;  or attending the Annual
     Meeting and voting your shares in person.

     Unless you decide to vote your shares in person at the Annual Meeting,  you
     should revoke your prior proxy in the same way you initially  submitted it,
     that is, by mail, telephone or Internet.

Q:   Is my vote confidential?

A:   Yes. Only EquiServe  Trust Company,  N.A.  ("EquiServe"),  the inspector of
     election,  and certain  employees have access to your voting  instructions.
     All written comments will be provided to KeySpan and only your name will be
     disclosed, unless you request that you are to remain anonymous.

Q:   Who will count the votes?

A:   EquiServe will tabulate the votes and act as inspector of election.

Q:   What if I get more than one proxy card?

A:   Your shares are  probably  registered  differently  or are in more than one
     account.  Sign and return all proxy cards to ensure that all of your shares
     are voted.  Please have all of your accounts registered exactly in the same
     name and social security number. You may do this by contacting our transfer
     agent, EquiServe, by calling 1-800-482- 3638.

Q:   What constitutes a quorum?

A:   As of the close of business on March 10, 2003, the Record Date, 156,926,647
     shares of Common  Stock were  issued  and  outstanding.  A majority  of the
     outstanding shares, present or represented by proxy,  constitutes a quorum.
     For purposes of determining the presence of a quorum, shares represented by
     abstentions and "broker non-votes" will be counted as present.  If you vote
     by proxy card or give a proxy by  telephone  or through the  Internet,  you
     will be  considered  part of the quorum.  In the  absence of a quorum,  the
     Annual Meeting may be adjourned.

Q:   What percentage of stock do the directors and officers own?

A:   The directors  and executive  officers as a group own less than 1.8% of our
     Common Stock as of March 10, 2003.

Q:   When are the shareholder proposals due for the 2004 Annual Meeting?

A:   Shareholder  proposals  for the 2004  Annual  Meeting  must be  received by
     KeySpan  at its  offices  at  One  MetroTech  Center,  Brooklyn,  New  York
     11201-3850,  Attention:  Corporate  Secretary,  by December 1, 2003,  to be
     considered by the Company for possible inclusion in the proxy materials for
     the  2004  Annual  Meeting.  In  addition,  all  shareholder  proposals  or
     nominations  for election as director  for the 2004 Annual  Meeting must be
     submitted to the Company in  accordance  with Section 2.7 of the  Company's
     By-Laws not less than 60 nor more than 90  calendar  days in advance of the

THE BOARD OF DIRECTORS

The Board of  Directors  is  responsible,  under New York law and the  Company's
Certificate  of  Incorporation  and By- Laws,  with  overseeing the business and
management  of the  Company.  The Board of Directors  met eleven  times  between
January 1 and December 31, 2002.

In  September  2002,  the Board of  Directors  amended the  Company's  Corporate
Governance  Guidelines,  which  had  been  adopted  in  1998,  in  light  of the
requirements imposed under the Sarbanes-Oxley Act of 2002 and the New York Stock
Exchange's   Corporate    Accountability   and   Listing   Standards   Committee
recommendations,  as well as in an effort to continue to apply best practices to
its corporate governance policies and procedures. The full text of the Company's
Corporate Governance  Guidelines is attached to this Proxy Statement as Appendix
A and can also be found  on the  Investor  Relations  section  of the  Company's
website (http://www.keyspanenergy.com).

Pursuant to our Corporate Governance Guidelines, the Board undertook a review of
director  independence.  As a result of this  review,  the  Board  affirmatively
determined  that all of the  directors  nominated  for  election  at the  Annual
Meeting are  independent of the Company and its  management  under the standards
set forth in the Corporate Governance  Guidelines,  with the exception of Robert
B. Catell,  who serves as Chief  Executive  Officer of the Company and J. Atwood
Ives, who served as the former Chairman and Chief  Executive  Officer of Eastern
Enterprises. KeySpan acquired Eastern Enterprises on November 8, 2000.

Committees of the Board

During 2002,  the Board  maintained  four  standing  committees  and two special
committees. The functions,  number of meetings held and composition of the Board
committees, as of December 31, 2002, are described below:

DIRECTOR COMPENSATION

Effective April 1, 2003, the directors will receive the following compensation:

     o    Non-employee and consulting directors:

                $43,500 annual retainer;
                $2,000 committee meeting fee;
                $5,000 committee chairman retainer; and
                925 shares of restricted stock (granted March 5, 2003)

     o    Employee directors:

                Receive no  additional  compensation for serving on the Board or
                its committees.

Directors' Deferred Compensation Plan

The Board of Directors has adopted the Directors' Deferred  Compensation Plan to
directly align the non-employee  directors' financial interest with those of the
shareholders.  The  Directors'  Deferred  Compensation  Plan  provides  all non-
employee  directors  with the  opportunity  to defer any  portion  of their cash
compensation  received as  directors,  up to 100%,  in exchange for Common Stock
equivalents  or  cash  equivalents.  Common  Stock  equivalents  are  valued  by
utilizing  the  average  of the high and low price per share of  KeySpan  common
stock  on the  first  trading  day of the  month  following  the  month in which
contributions  are received.  Dividends are paid on Common Stock  equivalents in
the same proportion as dividends paid on Common Stock. Compensation not deferred
and exchanged for Common Stock  equivalents  may be deferred into a cash account
bearing interest at the prime rate. Additionally,  a director may elect to defer
his or her  compensation by  participating  in the KeySpan  Investor  Program (a
dividend reinvestment plan). Upon retirement, death or termination of service as
a director,  all amounts in a director's Common Stock equivalent  account and/or
cash account  shall,  at the director's  election,  (i) be paid in a lump sum in
cash; (ii) be deferred for up to five years;  and/or (iii) be paid in the number
of annual installments,  up to ten, specified by the director.  The non-employee
directors are not entitled to benefits under any KeySpan retirement plan.

Additionally, Messrs. Fishman, McKessy and Miller also received compensation for
service as directors of the Company's wholly-owned subsidiary, KeySpan Services,
Inc.  ("KSI").  As non-employee  directors of KSI each received:  (i) an $18,000
annual  retainer and (ii) a $1,000  meeting fee for each meeting  attended.  KSI
held seven  meetings  during 2002.  Compensation  earned as directors of KSI was
also subject to the Directors'  Deferred  Compensation Plan. Since January 2003,
neither  Messrs.  Fishman,  McKessy,  Miller or any other  KeySpan non- employee
director is serving as a director of KSI.

Mr.  Catell also receives an annual grant of 2,000 stock options for his service
as a director of The Houston  Exploration Company ("Houston  Exploration").  The
Company's owns an approximate  56% interest in Houston  Exploration,  a publicly
traded company on the New York Stock Exchange under the symbol "THX".

McKessy and Edward D. Miller serving as chairperson.  None of such members is or
has been an officer or  employee  of  KeySpan  or any of its  subsidiaries.  The
Committee operates under a written charter adopted by the Board of Directors and
attached to this Proxy Statement as Appendix D.

During 2002, the Committee met seven times and directly engaged the HayGroup,  a
national  compensation  consultant,  to review  competitive  best  practices and
emerging  trends in both the  energy  and  utility  sector,  as well as  general
industry  compensation  levels in order to review the compensation for KeySpan's
directors and officers,  including the Named Executive Officers,  and to provide
advice with  respect to  incentive  compensation  plan  matters.  As part of the
HayGroup review process,  the Committee completed a comprehensive  assessment of
KeySpan's director and executive  compensation programs to ensure that KeySpan's
compensation  philosophy  and programs are  consistent  with best  practices and
provide a reasonable level of total compensation to the directors and officers.

The  Committee  reviews,  recommends  and  approves  changes  to  the  Company's
compensation  policies and programs for the Chief Executive  Officer,  the Named
Executive  Officers,   directors,   other  senior  executives  and  certain  key
employees.  In addition,  the Committee  makes  recommendations  concerning  the
Company's  employee  benefit  policies and exercises  such powers and makes such
other compensation  related  determinations as are entrusted to the Committee by
the Board of Directors.  After review and approval by the Committee,  all issues
relating to executive  and  director  compensation  are  submitted to the entire
Board for ratification when necessary.

Executive Compensation Philosophy and Policies

The  philosophy  of KeySpan with respect to executive  compensation  is that the
Chief  Executive   Officer  and  other  executives   should  be  compensated  at
market-competitive  levels to attract,  motivate, and retain talented executives
needed to achieve  KeySpan's  vision of being the premier  energy company in the
Northeast.  Through the  Committee,  the Board of Directors has developed a "pay
for   performance"   executive   compensation   philosophy   and   approved  the
implementation  of a total  compensation  plan  designed to focus  attention  on
KeySpan's strategic business initiatives and financial  performance  objectives.
The Committee adheres to the following compensation policies, which are intended
to facilitate the achievement of KeySpan's  business  strategies and further the
Company's vision:

     o    The  executive   compensation   program   should   emphasize  pay  for
          performance  and  encourage  retention of those  employees who enhance
          KeySpan's performance;

     o    Compensation  arrangements will maintain a reasonable  balance between
          base salary, annual and long- term equity-based incentive compensation
          and be designed to focus such executives on the long-term interests of
          the shareholders and creating value for the shareholders;

     o    The incentive  compensation  program for executives  should strengthen
          the link of incentive compensation to the achievement of financial and
          strategic objectives, which are set in advance by the Committee;

     o    In determining  executive  compensation levels for base salary, annual
          and  long-term   compensation,   the  compensation  levels  should  be
          competitive  with  compensation  levels  for  executive  positions  of
          similar scope for general  industry in the  metropolitan New York City
          and Boston  areas,  as well as peer  energy  companies.  If  KeySpan's
          performance exceeds that of the comparable group,  compensation should
          be above the median;  likewise,  if KeySpan's  performance falls below
          that of the group, the compensation paid to executives should be below
          the median of the comparable companies.

Components of Compensation

The Committee compares total compensation levels for KeySpan's executives to the
compensation  paid to executives in comparable  general industry and peer energy
companies.  In this regard, the Committee uses analyses prepared by the HayGroup
to review the compensation  levels of executives in the energy industry,  and in
the regional and  national  marketplace.  In  addition,  the  Committee  reviews
compensation  data  for  executive  positions  comparable  in  scope to those in
general  industry  companies in the metropolitan New York City and Boston areas.
The companies analyzed in this process tend to have national business operations
and have  positions  that are similar in scope with  comparable  revenue size or
employment  levels.  Through this process,  the Committee  identifies the median
compensation  level,  both with respect to base salary and the overall executive
compensation program.



                                       10





The Committee  strives to ensure that  compensation for the Company's  executive
officers provides a direct link to strategic  financial measures and shareholder
value.  To achieve  this  performance  linkage,  KeySpan has  established  three
programs  for the direct  compensation  of executive  officers:  the Base Salary
Program,  the Corporate  Annual  Incentive  Compensation  Plan and the Long-Term
Performance  Incentive  Compensation  Plan.  The intent of these  programs is to
place increased  emphasis on performance  based pay and reduced emphasis on base
salary  in  determining  total  compensation.  Each  of the  three  programs  is
discussed in greater detail below.

The Base Salary Program

In  setting  base  salary  levels  for the Chief  Executive  Officer,  the Named
Executive  Officers and other executive  officers,  the Committee  considers the
competitive  market data for executives in comparable  positions in other energy
and general industry markets.  In setting base salary levels,  KeySpan currently
targets the 50th percentile of the comparable  labor market.  The Committee also
considers the experience level and actual performance  achieved by the executive
as it relates to  KeySpan's  corporate  goals in setting such  executive's  base
salary.

When Mr.  Catell was  promoted to and elected as  Chairman  and Chief  Executive
Officer on July 31, 1998, KeySpan entered into an employment  agreement with Mr.
Catell  that  provided  a base  salary of  $700,000  per year,  subject  to such
increases that may be approved by the Board.  Base salary  increases  based upon
performance have been determined on an annual basis.  Effective January 1, 2002,
the Committee  and the Board  approved an increase in Mr.  Catell's  annual base
salary to $938,000.  As the Company  continues to align base pay to  competitive
market levels, the base salary level for the Chief Executive Officer,  the Named
Executive Officers and other executive officers,  compared to competitive market
data, is generally at the 50th percentile of comparable  positions at this time.
Based upon an assessment of the emerging trends in the energy industry,  and the
Committee's  desire to place more emphasis upon  achieving  annual and long-term
performance  results,  the Committee has determined  that Mr. Catell,  the Named
Executive  Officers and other  executive  officers  will not receive base salary
increases during 2003.

The Corporate Annual Incentive Compensation Plan

The Board of Directors adopted the Corporate Annual Incentive  Compensation Plan
(the  "Corporate  Plan") in  September  1998.  The awards to be earned under the
Corporate Plan will be paid as cash based upon annual performance  results.  For
2002, the performance  measurement period included the twelve-month  period from
January 1, 2002 to December  31,  2002.  The awards for this period were paid in
March 2003. The Corporate Plan provides annual  incentive awards to officers and
all  management  employees  who,  by the  nature  and scope of their  positions,
regularly and directly make a significant contribution to the success of KeySpan
in the achievement of corporate goals that the Committee  believes are important
to the shareholders of KeySpan.  The specific  corporate goals for the Corporate
Plan are  established  by management  and reviewed and approved by the Committee
and  the  Board  of  Directors.  The  Corporate  Plan  is  intended  to  improve
shareholder return and corporate  performance and includes goals which encourage
growth  in  earnings  per  share,   improved  cash  flow,   corporate  earnings,
competitive  positioning,  customer satisfaction,  control of operating expenses
and other strategic initiatives.  In addition, a corporate diversity measure was
included as a performance  measure in the Corporate Plan.  Incentive awards as a
percentage of cumulative  salary paid in connection  with 2002 results are based
upon both Company and strategic business group performance.  The incentive award
ranges are  established  annually by the Committee for eligible  executives  and
management  employees in the Corporate Plan. Incentive award levels are intended
to provide  awards that are  competitive  within the  industry  at target  award
levels when performance results are achieved.

The 2002 Corporate  Plan provided for award  opportunities  to executives  which
ranged from zero, if below target  performance  levels,  up to 80% of cumulative
paid salary at target performance levels, with a maximum award potential of 160%
of cumulative  paid salary at maximum  performance  levels.  For 2002, the Chief
Executive Officer had a target award level of 80% of cumulative paid salary with
performance  criteria  based upon  consolidated  earnings per share,  cash flow,
customer  satisfaction,  diversity and other strategic  initiatives.  Based upon
actual  2002  results,  an award  payout of 116% of  cumulative  paid salary was
approved by the  Committee and paid in March 2003.  The amount  reflected in the
Summary  Compensation  table that was paid in March 2002 for performance  during
2001  represented  a  payout  of  32%  of  cumulative  paid  salary.   Upon  the
recommendation  of the HayGroup and the approval of the Committee and the Board,
for the year 2003, the Chief Executive  Officer's target award remains at 80% of
cumulative  paid salary.  All executives in the Corporate Plan have a portion of
their incentive award linked directly to overall corporate performance goals and
to the results achieved in their respective strategic business group.




                                       11





Pursuant  to the  Officers'  Deferred  Stock Unit Plan and  consistent  with the
Company's  desire to  increase  officer  stock  ownership,  the Chief  Executive
Officer,  the Named Executive Officers and certain other executives may elect to
defer between 10% to 50% of their annual cash award under the Corporate  Plan to
purchase  deferred  stock units  ("DSUs"),  which track the  performance  of the
Company's  Common Stock but do not possess voting rights.  Executives  will also
receive a 20% match by the Company on the amount deferred in each year. The DSUs
must be  deferred  until  retirement  or  resignation  and are payable in Common
Stock. The match on the deferral is also payable in Common Stock upon retirement
or in the event of an executive's  disability,  death or upon change of control.
The match is  forfeited  in the event of the  executive's  resignation  prior to
retirement.  The Chief Executive Officer elected to defer 50% of his 2001 annual
award,  paid in March 2002 and 50% of his 2002 annual award, paid in March 2003,
into a DSU account.

The Long-Term Performance Incentive Compensation Plan

As a result of the Committee's review of the  competitiveness of KeySpan's total
compensation program, and the HayGroup's review of the long-term incentive plans
used by a majority of energy companies, the Committee recommended, and the Board
of Directors adopted, the KeySpan Long-Term Performance  Incentive  Compensation
Plan (the "Incentive  Plan") in March 1999. The Incentive Plan was  subsequently
approved by the shareholders at the May 1999 Annual Meeting of Shareholders.  On
May 10, 2001,  shareholders  approved an amendment to the  Incentive  Plan which
increased the authorized  shares to a total of 19,250,000.  As of March 5, 2003,
approximately  14,221,285 stock options,  127,408  restricted shares and 189,500
performance shares have been awarded under the Incentive Plan.

The  Incentive  Plan  provides  for  the  award  of  incentive   stock  options,
non-qualified  stock options,  performance  shares and restricted  shares to key
employees,  directors  and  consultants  of  KeySpan  and  its  subsidiaries  as
determined by the  Committee.  The purpose of the Incentive  Plan is to optimize
KeySpan's  performance  through  incentives that directly link the participant's
goals to those of KeySpan's  shareholders and to attract and retain participants
who make significant contributions to the success of KeySpan.

The stock option  component of the Incentive Plan entitles the  participants  to
purchase shares of Common Stock at an exercise price per share determined by the
Committee  that is no less than the closing price of the Common Stock on the New
York Stock  Exchange on the date of the grant.  On September 26, 2002, the Board
of Directors adopted upon the Committee's recommendation, Statement of Financial
Accounting   Statement   ("SFAS")  123  and  began   expensing   stock   options
prospectively commencing in 2003.

On March 1, 2002, based upon the performance of the Chief Executive Officer, the
Committee approved a grant to Mr. Catell of 372,000  non-qualified stock options
to purchase Common Stock at an exercise price of $32.66 (vesting over a three or
five-year  period,   depending  upon  Company  performance,   or  pro-rata  upon
retirement  using  the  full  months  of  employment  from  the  grant  date  to
retirement,  divided by 36 months).  In  addition,  Mr.  Catell was also awarded
13,295  shares of restricted  stock,  which  included a share price  performance
target linked to the lapse of restrictions.  The minimum  restriction  period is
two years.  If the target  share price is met at any time during years three and
four, the restrictions will lapse. However, if the target is not achieved by the
end of the fourth year,  restrictions  will not lapse until the end of the sixth
year. In the event of retirement,  the  restrictions  on the shares granted will
lapse on a pro-rata  basis  using the full months of  employment  from the grant
date to retirement, divided by 48 months.

Since 2001, the option award process has included a performance  goal feature in
the stock  option  vesting  schedule  for officers  which  directly  links total
shareholder return ("TSR") for KeySpan Common Stock to the options granted.  The
TSR goal  measures the total return to  shareholders  of KeySpan  Common  Stock,
including  price  appreciation  and  dividends.  KeySpan's  performance  will be
measured  against the S&P Utility  Group over a three-year  performance  period.
Options were granted with a five-year pro-rata vesting schedule, rather than the
traditional  three-year  pro-rata vesting schedule.  If KeySpan achieves its TSR
goal at the end of the three-year  performance  period,  then those options that
are not yet vested  will vest  immediately.  If the TSR goal is not  achieved in
year  three,  the  remaining  unvested  options  will  continue  to  vest on the
five-year schedule.

Beginning in 2003, in order to further align the interests of executive officers
to those of the  shareholders,  awards of  performance  shares to officers  were
approved by the  Committee and the Board.  Performance  shares have been granted
with a  three-year  performance  period  with a  threshold,  target and  maximum
performance   level.   Consistent  with  the  stock  option   performance  goal,
performance shares will be measured by comparing KeySpan's cumulative three-year
TSR. At threshold performance, 50% of the award shall be earned; at target, 100%
of the award shall be earned; and at maximum, 150% of the award shall be earned.
If the threshold level of performance is not achieved all shares granted



                                       12





shall be  forfeited.  In the event of  retirement,  performance  shares shall be
distributed based upon results achieved at the end of the performance period and
pro-rated through the date of retirement.

On March 5,  2003,  the  Committee  approved  a grant to Mr.  Catell of  208,800
non-qualified  stock  options to purchase  Common Stock at an exercise  price of
$32.40 and 32,700  performance  shares.  The options  shall vest over a three or
five-year period,  depending upon the Company's  performance under the TSR goal.
The goal for the  three-year  TSR has been set at the median of the S&P  Utility
Group.  In the event of  retirement,  the options shall vest pro-rata  using the
number of full months of employment  from the grant date to retirement,  divided
by 36 months.

During 2003, an aggregate of 1,194,200  non-qualified  stock options and 188,500
performance  shares  were  granted  to all  officers  as a group.  The grants of
non-qualified  stock  options and  performance  shares  were made to  executives
generally  determined on the basis of the  executive's  performance and position
within  KeySpan  and the level of such  executive's  compensation  to focus such
executives on the long-term interests of shareholders.

The Committee  believes  that  performance  based stock options and  performance
shares are directly linked to KeySpan's shareholder value.  Consistent with this
philosophy,  the Committee has adopted stock ownership  guidelines for directors
and  officers  relating  to their  ownership  of  KeySpan  Common  Stock.  These
guidelines  encourage  increased  ownership  of  KeySpan  Common  Stock  and the
retention of  underlying  shares upon the exercise of stock options by directors
and officers.  Pursuant to the guidelines, it is encouraged that the officers of
the Company  should have ownership of KeySpan Common Stock based upon a multiple
of their base  salary  which has been set at one times  base  salary at the Vice
President  level to up to five times  base  salary  for the  Chairman  and Chief
Executive  Officer.  These ownership  levels should be reached within five years
from the  adoption  of these  guidelines.  Officers  not  currently  meeting the
guidelines are encouraged when  exercising  stock options to retain a portion of
the after-tax gain of such  transaction  in KeySpan  Common Stock.  As owners of
KeySpan  Common  Stock,  executives  are fully aligned with the interests of our
shareholders and the future success of KeySpan.

Policy with Respect to Section 162(m) Deduction Limit

Under  Section  162(m) of the  Internal  Revenue  Code of 1986,  as amended (the
"Code"),  the Company cannot deduct compensation in excess of $1,000,000 paid in
any year to the Chief Executive  Officer or any of the Named Executive  Officers
whose  compensation  must be detailed in the Proxy  Statement.  Certain  benefit
plans and  compensation  paid  under  plans that are  performance  based are not
subject to the $1,000,000  annual limit if certain  requirements  are satisfied.
Although  the  Company's  compensation  policy is  generally  designed to relate
compensation  to  performance,  certain  payments  do not meet such  requirement
because they allow the Committee and the Board to exercise discretion in setting
compensation.  The Committee is of the opinion that it is in the Company's  best
interest  for the  Committee  and the  Board to  retain  discretion  in order to
preserve  flexibility in  compensating  such executive  officers,  especially in
light of an increasingly competitive marketplace.

Conclusion

The  Committee  believes  that  KeySpan's  executive  compensation  policies and
programs serve both the interests of KeySpan and its  shareholders  effectively.
The various  compensation  programs  are  appropriately  balanced to provide the
motivation for executives to contribute to KeySpan's overall success and enhance
the value of KeySpan for the  shareholders'  benefit,  and are  consistent  with
compensation  programs  for  companies  of similar  size in both the utility and
energy industry segments.

The Committee  will  continue to monitor the  effectiveness  of KeySpan's  total
compensation program to meet the current and the future needs of KeySpan.

          applies upon achievement of certain prescribed goals).

     (2)  Options have been valued using the Black-Scholes  option pricing model
          adapted to reflect the specific  provisions of the Incentive  Plan and
          related  assumptions  regarding  exercisability.  The values shown are
          theoretical and do not necessarily  reflect the actual values that may
          be realized upon the future exercise of the options.  Any actual value
          will result to the extent that the market value of the Common Stock at
          a future date exceeds the exercise price. Assumptions for modeling are
          based  on the  dividend  yield,  risk-free  rate of  return,  standard
          deviation  of prices  over a relevant  period as of the grant date and
          the expected lives of the options.

The number of years of credited service for R. B. Catell, the Chairman and Chief
Executive  Officer,  based on  continued  service to age 69 and  pursuant to the
terms of his employment  agreement,  will result in Mr. Catell  retiring with 47
years of service.  The number of years of credited service for each of the other
Named Executive  Officers based on continued service with the Company to age 65,
normal  retirement  age, will be as follows:  W. P. Parker Jr. - 43 years, R. J.
Fani - 42 years, S.L. Zelkowitz - 17 years and G. Luterman - 10 years.

The Code limits the annual  compensation  taken into  consideration for, and the
maximum annual retirement benefits payable to, a participant under the Company's
retirement   plan.   For  2002,   these  limits  were   $200,000  and  $160,000,
respectively.  Annual retirement  benefits  attributable to amounts in excess of
these limits are provided for under the  Company's  excess  benefit plan and not
under the Company's retirement plan.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

Neither Messrs. Elliott, Jones, Larocca,  McKessy or Miller, the current members
of the Compensation and Nominating  Committee nor Mr. James Riordan, who retired
from the Board and the Compensation  and Nominating  Committee on May 9, 2002 is
an officer or employee,  or former officer or employee, of KeySpan or any of its
subsidiaries.  No  interlocking  relationship  exists  between  the  members  of
KeySpan's  Board or  Compensation  and  Nominating  Committee  and the  board of
directors  or  compensation  committee  of any other  company,  nor has any such
interlocking relationship existed in the past.

AGREEMENTS WITH EXECUTIVES

Employment Agreements

In September 1998, KeySpan entered into an employment  agreement with Mr. Robert
B. Catell relating to his services as Chairman and Chief Executive Officer which
was amended on February 24, 2000 and June 26,  2002.  The  agreement  covers the
period  beginning  July 31, 1998 and ending July 31,  2005.  In addition to base
salary, annual and long-term incentive compensation and other employee benefits,
Mr. Catell's employment  agreement provides for severance benefits to be paid to
him in the event his employment is terminated by KeySpan without cause or if Mr.
Catell terminates his employment for good reason.  The severance  benefits to be
provided during the severance period would include: (a) payment to Mr. Catell in
a single lump sum of (i) all accrued  obligations and (ii) the aggregate  amount
of salary and annual incentive  compensation  that he would have received had he
remained  employed  through  the end of the  employment  period;  (b)  continued
accrual of Supplemental  Executive  Retirement Plan benefits (as provided in the
agreement)  during  the  severance  period;  and (c)  continuation  of all other
employment  benefits,  as if he had  remained  employed  by  KeySpan  during the
severance period.  If Mr. Catell  voluntarily  terminates his employment,  other
than for good  reason,  the  Company  shall pay the accrued  obligations  to Mr.
Catell and he shall be  entitled to  supplemental  retirement  benefits.  If Mr.
Catell's employment is terminated following a "change of control" of KeySpan (as
defined in the  agreement),  the severance  period is defined to mean the period
from the date of termination  through the end of the employment  period,  or, if
longer, the third anniversary of the date of termination.

The  Company has  entered  into a  supplemental  retirement  agreement  with Mr.
Zelkowitz.  The  agreement  provides one year of credited  service for each year
worked,  up to a maximum of ten years, in the  calculation of pension  benefits.
The  maximum  enhancement  would  provide an  incremental  benefit of 15% of the
executive's  final  five-year  average  earnings under the current  pension plan
formula.  In addition,  at retirement,  Mr.  Zelkowitz will receive Company paid
medical and dental coverage at the same level of employee contribution in effect
at  retirement,  which will be  grossed  up for  federal  and state  taxes.  Mr.
Zelkowitz must remain employed  through  December 2006 in order to fully vest in
this benefit.  For retirement prior to this date, the benefit will vest pro-rata
over a five-year  period or 20% per year.  The  earliest  Mr.  Zelkowitz  may be
eligible for a pro-rata benefit will be on October 1, 2003, the date he vests in
the  Company's  retirement  plan. If there is a  change-in-control,  termination
without cause, or if Mr. Zelkowitz  resigns for good reason,  then the five-year
vesting  requirement  will be waived and Mr.  Zelkowitz will immediately vest in
all additional service provided for in this agreement.

The  Company has  entered  into a  supplemental  retirement  agreement  with Mr.
Luterman.  The  agreement  provides  that Mr.  Luterman  will  receive an annual
supplemental   retirement   amount  determined  by  multiplying  Mr.  Luterman's
qualified  and  non-qualified  pension  accruals  at age 62 by 35%.  This annual
supplemental   amount  will  be  aggregated   with  his  actual   qualified  and
non-qualified   pension  benefit  at  his  retirement  date.  In  addition,   at
retirement,  Mr.  Luterman will receive Company paid medical and dental coverage
at the same level of employee  contribution in effect at retirement,  which will
be grossed up for federal and state taxes.  Mr.  Luterman  must remain  employed
through June 2005 in order to vest fully in this benefit.  For retirement  prior
to this date,  the  supplemental  amount will vest  pro-rata  over a  three-year
period. The earliest Mr. Luterman may be eligible for a pro-rata benefit will be
on June 2003. If there is a change-in-control,  termination without cause, or if
Mr. Luterman resigns for good reason,  then the three-year  vesting  requirement
will be waived and Mr. Luterman will immediately vest in all additional  service
provided for in this agreement.





                                       18




Senior Executive Change of Control Severance Plan

As of April 1, 2003,  with the  exception  of Mr.  Catell,  53  officers  of the
Company and certain subsidiaries will participate in the Senior Executive Change
of Control Severance Plan (the "Change of Control Plan").  The Change of Control
Plan, as amended,  provides for the payment of severance and other benefits upon
certain  qualifying  terminations of such  executives  within two (2) years of a
"change of control"  of the Company (as defined in the Change of Control  Plan).
The  protection  period under the Change of Control Plan commences upon the date
that KeySpan enters into a definitive agreement, the transaction contemplated by
which will, when consummated, constitute a change of control under the Change of
Control  Plan and will  continue  for a period of two years after the  effective
date of the actual change of control.  The benefits  payable under the Change of
Control Plan generally provide for (i) the payment of the sum of the executive's
base salary,  incentive compensation and compensation previously deferred by the
executive,  all through the date of  termination;  (ii) the payment of an amount
equal to three times an executive's  base salary and incentive  compensation for
any President,  any Executive Vice President and certain Senior Vice  Presidents
of KeySpan and certain subsidiaries and two times an executive's base salary and
incentive  compensation  for other officers;  (iii) the payment of amounts under
retirement  plans;  and (iv) the  continuation  of certain other  benefits for a
period of two to three years  depending  on the  executive's  position  with the
Company.  The Change of Control Plan expires  October 30, 2003,  unless extended
for an additional period by the Board of Directors;  provided that,  following a
change of control, the Change of Control Plan shall continue until after all the
executives who become  entitled to any payments  thereunder  shall have received
such payments in full.

Security Ownership of Certain Beneficial Owners

As of March 10,  2003,  there were no  beneficial  owners of more than 5% of the
Company's Common Stock.

PROPOSAL  2.  RATIFICATION  OF  DELOITTE  &  TOUCHE  LLP AS  INDEPENDENT  PUBLIC
              ACCOUNTANTS

In accordance  with the  recommendations  of its Audit  Committee,  the Board of
Directors recommends that the shareholders ratify the appointment of the firm of
Deloitte & Touche LLP ("Deloitte & Touche"),  as independent  public accountants
to audit the books, records and accounts of KeySpan and its subsidiaries for the
year ending December 31, 2003.

Arthur Andersen LLP ("Arthur  Andersen") served as KeySpan's  independent public
accountants  from May 1998  through  March 29,  2002,  when  KeySpan's  Board of
Directors,  upon recommendation of the Audit Committee,  determined not to renew
the engagement of Arthur Andersen and appointed Deloitte & Touche as independent
public  accountants.  During  the  fiscal  years  ended  2000  and  2001 and the
subsequent  interim period through March 29, 2002,  there were no reports on the
financial statements of the Company by Arthur Andersen that contained an adverse
opinion  or a  disclaimer  of  opinion,  or  was  qualified  or  modified  as to
uncertainty,  audit scope,  or  accounting  principles.  During the fiscal years
ended 2000 and 2001and the  subsequent  interim  period  through March 29, 2002,
there were no  disagreements  with Arthur  Andersen on any matter of  accounting
principles or practices,  financial  statement  disclosure or auditing  scope or
procedure which, if not resolved to the  satisfaction of Arthur Andersen,  would
have  caused  the  firm  to  make  reference  to  the  subject  matter  of  such
disagreements in connection with its report.

A  representative  of  Deloitte & Touche  will  attend the  Annual  Meeting,  be
available to answer  shareholder  questions and have the  opportunity  to make a
statement if he or she desires to do so.

The affirmative  vote of a majority of the votes cast at the meeting is required
for approval of this proposal.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE FOR THIS PROPOSAL.


FISCAL YEAR 2002 AUDIT FIRM FEE SUMMARY

The  following  table  provides  information  on the  aggregate  fees billed for
services  performed  by  Deloitte & Touche LLP,  the member  firms of Deloitte &
Touche Tohmatsu, and their respective affiliates for the year ended December 31,
2002:



         Audit Fees                               $   1,822,925
         Financial Information Systems
         Design and Implementation Fees           $           0
         All Other Fees                           $     969,775 (1)
                                                      ---------
         Total                                    $   2,792,700

(1)  All other fees were generally comprised of fees for audit related services,
     tax services and the performance of agreed upon  procedures.  Audit related
     fees were approximately $310,875 and were for services generally related to
     benefit plans,  statutory audits of subsidiaries,  and comfort letters. Tax
     service fees were approximately  $280,300 and generally include services to
     perform tax consultation and tax services.  Approximately $378,600 of other
     fees were related to the performance of agreed upon procedures.

The Audit  Committee has reviewed the nature and scope of the services  provided
by  Deloitte  & Touche  and  considers  such to have  been  compatible  with the
maintenance  of Deloitte & Touche's  independence  throughout its service to the
Company.



                                       20




REPORT OF THE AUDIT COMMITTEE

The Audit  Committee  of the Board of  Directors  of KeySpan is composed of five
non-employee  directors.  The members of the Audit  Committee are independent as
such term is defined in the rules of the New York Stock  Exchange and Securities
and Exchange Commission (the"SEC"). The Chair and two other members of the Audit
Committee have accounting or related financial management  expertise.  The Audit
Committee operates under a written charter adopted by the Board of Directors and
attached to this Proxy Statement as Appendix C.

Pursuant to its Charter,  the Audit Committee provides oversight with respect to
the quality and integrity of the Company's financial statements; compliance with
legal and regulatory requirements;  the independent auditor's qualifications and
independence;  the  performance  of the Company's  internal  audit  function and
independent  auditors,  the  business  practices  and ethical  standards  of the
Company  and the  preparation  of all  reports  required  to be  included in the
Company's annual Proxy Statement.

Additionally,  in  accordance  with  the  Audit  Committee  Charter,  the  Audit
Committee reviews the scope of the audit and approves the nature and cost of all
audit and non-audit services.  Non-audit services must be approved in advance of
the rendering of services. The Audit Committee has reviewed the nature and scope
of the services  provided by Deloitte & Touche and  considers  such to have been
compatible with the maintenance of Deloitte & Touche's  independence  throughout
its service to the Company.

The  Audit  Committee  has also  determined  that the  scope of  services  to be
provided  by  Deloitte & Touche in 2003 will  generally  be limited to audit and
audit related  services and tax services.  The Audit  Committee  will  expressly
approve the provision of any services by Deloitte & Touche  outside the scope of
the foregoing  services.  Notwithstanding  the  foregoing,  pre-approval  is not
necessary for minor non-audit  services if: (i) the aggregate amount of all such
non-audit  services  provided  to the  Company  constitutes  not more  than five
percent of the total  amount of  revenues  paid by the  Company  to its  auditor
during the fiscal year in which the non-audit  services are provided;  (ii) such
services were not  recognized by the Company at the time of the engagement to be
non-audit  services;  and  (iii)  such  services  are  promptly  brought  to the
attention of the Committee and approved  prior to the completion of the audit by
the Committee or its Chairman pursuant to delegated authority.

We have reviewed and discussed with management the Company's  audited  financial
statements as of, and for, the year ended December 31, 2002.

We have  discussed  with the  independent  auditors  the matters  required to be
discussed by Statement on Auditing  Standards No. 61,  Communication  with Audit
Committees,  as  amended,  by the  Auditing  Standards  Board  of  the  American
Institute of Certified Public Accountants.

We have  received and reviewed the written  disclosures  and the letter from the
independent  auditors  required  by  Independence  Standard  No.1,  Independence
Discussions with Audit  Committees,  as amended,  by the Independence  Standards
Board,  discussed  with the  auditors  any  relationships  that may impact their
objectivity  and  independence  and  satisfied  ourselves  as to  the  auditors'
independence.

Based on the reviews and  discussions  referred to above,  we recommended to the
Board of Directors that the audited  financial  statements  referred to above be
included in the Company's Annual Report on Form 10-K for the year ended December
31, 2002.

PROPOSAL 3. AMENDMENTS TO THE EMPLOYEE DISCOUNT STOCK PURCHASE PLAN

The Board of Directors  has approved and is  unanimously  recommending  that the
shareholders  approve amendments to the KeySpan Employee Discount Stock Purchase
Plan (the "Stock  Plan") to: (i)  increase  the number of shares of Common Stock
authorized for issuance under the Stock Plan by 1,000,000 shares to an aggregate
of  1,750,000  shares and (ii) modify the pricing  methodology  for any purchase
made on or after July 1, 2003 by using the average of the high and low price per
share of KeySpan  Common Stock on the first  trading day of the month  following
the month of contribution to the Stock Plan.

Reason for Amendment

The Stock Plan is designed to  encourage  ownership  of KeySpan  Common Stock by
eligible  employees of KeySpan or its  wholly-owned  subsidiaries by providing a
convenient and  systematic  method for employee  acquisitions  of KeySpan Common
Stock. As of December 31, 2002, approximately 4,300 employees participate in the
Stock Plan and  approximately  422,000  shares have been issued  under the Stock
Plan.  There remains only 328,000 shares  available for issuance under the Stock
Plan. An increase in the number of shares authorized  pursuant to the Stock Plan
is  necessary  in order to meet the  anticipated  needs of the Stock Plan in the
coming years.  Since  KeySpan's  acquisition of Eastern  Enterprises in November
2000, KeySpan has grown its employee base from approximately  7,800 employees to
over 13,000  employees.  As a result of our expanded employee base and increased
interest on the part of our  employees in  participating  in the Stock Plan,  we
anticipate  that we will exceed our current  authorized  shares  pursuant to the
Stock Plan in the second quarter of 2004. Therefore,  it is recommended that the
number of shares of Common Stock authorized for issuance under the Stock Plan be
increased by 1,000,000 shares to an aggregate of 1,750,000 shares. Additionally,
the amendment  seeks to modify the pricing  methodology  used for the Stock Plan
for any purchase made on or after July 1, 2003, by using the average of the high
and low price per share of KeySpan  Common Stock on the first trading day of the
month  following the month of  contribution  to the Stock Plan.  Currently,  the
Stock Plan provides for purchases on a quarterly basis based on the lower of the
average  of the high and low price per share of KeySpan  Common  Stock on either
the  first or last  business  day of the prior  quarter.  The  amendment  to the
pricing  methodology  is  recommended  as a result  of the  Company's  change in
accounting  policy  through  the  implementation  of SFAS 123.  Such change will
result in an incremental  accounting expense under FAS 123. In order to minimize
this incremental accounting expense, it is recommended that the Stock Plan adopt
the new pricing methodology.

Description of the Stock Plan

The Stock Plan was originally  approved by the  shareholders  at the 1999 Annual
Meeting  and an  amendment  to  increase  the  number of  authorized  shares was
approved  at the  2001  Annual  Meeting.  The  Stock  Plan,  with  the  proposed
amendments,  will provide that  effective July 1, 2003,  eligible  employees may
purchase  Common Stock on a monthly basis whereby the price will be up to 85% of
the average of the high and low price per share of KeySpan  Common  Stock on the
first trading day of the month  following the month of contribution to the Stock
Plan.  Although the Stock Plan may offer up to an 15% discount,  only a discount
of 10% of such price is currently  being  offered to  participants  in the Stock
Plan.  Generally,  all of the approximately  13,000 employees of KeySpan and its
wholly-owned  subsidiaries are eligible to participate in the Stock Plan, except
(i)  employees  who have not been on the payroll for at least three months as of
the beginning of a purchase period;  (ii) employees who customarily are employed
less than three months in any calendar year;  (iii) employees who work less than
20 hours per week; and (iv) non-employee directors.

Employees will be able to purchase shares by payroll deduction. In each purchase
period,  the total payments by an employee to purchase  shares cannot exceed 20%
of his or her base  pay at the  beginning  of such  period.  Moreover,  the fair
market value of shares purchased by an employee under the Stock Plan, during any
calendar  year  cannot  exceed  $25,000.  The  annual  contribution  limit  has,
therefore, been set at $20,000. In addition, an employee may not purchase shares
if the purchase  would cause him or her to own 5% or more of the total  combined
voting power or value of all shares of KeySpan Common Stock.

Employees may also sell any or all of their shares acquired under the Stock Plan
at a price  based  on the  weighted  average  of all  shares  sold  by the  plan
administrator  during a given  selling  period,  adjusted  to exclude  brokerage
commissions.





                                       22



The  proceeds  received by the Company from  purchases  under the Stock Plan are
used for general  corporate  purposes or for the  purchase of shares on the open
market on behalf of a participant.

On March 10, 2003,  the closing  price of KeySpan's  Common Stock as reported on
the NYSE listing of composite transactions was $31.88 per share.

The following  resolution  will be proposed for approval by the  shareholders of
KeySpan's Common Stock:

     RESOLVED,  that the Employee  Discount  Stock Purchase Plan, be amended to:
(i) increase the number of shares of Common Stock  authorized for issuance under
the Stock Plan by 1,000,000  shares to an aggregate of 1,750,000 shares and (ii)
modify the pricing methodology for any purchase made on or after July 1, 2003 by
using the average of the high and low price per share of KeySpan Common Stock on
the first trading day of the month  following the month of  contribution  to the
Stock Plan.

The affirmative  vote of a majority of the votes cast at the meeting is required
for approval of this proposal.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE FOR THIS PROPOSAL.

NEW PLAN BENEFITS

Participation in the Stock Plan is on a voluntary basis and,  therefore,  future
participation in the Stock Plan cannot be determined.  Accordingly, the benefits
and amounts  received  pursuant to the Stock Plan cannot be  determined.  During
2002,  the Named  Executive  Officers  purchased the following  number of shares
under the Stock Plan: R. B. Catell - 159 shares,  W. P. Parker Jr. - 139 shares,
R. J. Fani - 677  shares,  S.L.  Zelkowitz  - 576 shares  and G.  Luterman - 459
shares.  The executive  officers as a group purchased 7,448 shares and all other
employees as a group purchased  213,145 shares.  Non-employee  directors are not
eligible to participate in the Stock Plan.

Directors' Deferred Compensation Plan

The Directors'  Deferred  Compensation Plan provides all non-employee  directors
with the opportunity to defer any portion of their cash compensation received as
directors,  up to  100%,  in  exchange  for  Common  Stock  equivalents  or cash
equivalents. Common Stock equivalents are valued by utilizing the average of the
high and low price per share of KeySpan common stock on the first trading day of
the month following the month in which contributions are received. Dividends are
paid on Common Stock  equivalents  in the same  proportion as dividends  paid on
Common  Stock.   Compensation  not  deferred  and  exchanged  for  Common  Stock
equivalents,  may be deferred into a cash account bearing  interest at the prime
rate.  Upon  retirement,  death or  termination  of service as a  director,  all
amounts in a director's  Common  Stock  equivalent  account  and/or cash account
shall,  at the director's  election,  (i) be paid in a lump sum in cash; (ii) be
deferred  for up to five  years;  and/or  (iii) be paid in the  number of annual
installments,  up to ten, specified by the director.  The non-employee directors

PROPOSAL 4.     SHAREHOLDER PROPOSAL

The following  shareholder  proposal has been  submitted by Mr. Emil Rossi.  The
address and stock  ownership of Mr.  Rossi will be  furnished  by the  Corporate
Secretary  to any  person,  orally or in writing  as  requested,  promptly  upon
receipt of any oral or written  request  therefor.  Mr.  Rossi has  advised  the
Company that either he, or his designee,  plan to present the following proposal
at the Annual Meeting:

The proposal:
                           Shareholder Vote on Poison
     Pills This topic won an average 60% - yes vote at 50 companies in 2002


This is to  recommend  that the  Board  of  Directors  redeem  any  poison  pill
previously issued (if applicable) and not adopt or extend any poison pill unless
such adoption or extension has been submitted to a shareholder vote.

The  following  statement  has been  provided  in  support  of this  shareholder
proposal:

Harvard Report

A 2001 Harvard Business School study found that good corporate governance (which
took into  account  whether  a company  has a poison  pill) was  positively  and
significantly  related  to  company  value.  This  study,   conducted  with  the
University of Pennsylvania's  Wharton School,  reviewed the relationship between
the corporate  governance index for 1,500 companies and company performance from
1990 to 1999.

Some  believe  that a company with a good  governance  will perform  better over
time, leading to a higher stock price.  Others see good governance as a means of
reducing  risk,  as they  believe  it  decreases  the  likelihood  of bad things
happening to a company.

Since the 1980s Fidelity,  a mutual fund giant with $800 billion  invested,  has
withheld votes for directors at companies that have approved poison pills,  Wall
Street Journal, June 12, 2002.

Council of Institutional Investors Recommendation

The  Council of  Institutional  Investors  www.cii.org  an  organization  of 120
pension funds which invests $1.5 trillion,  called for  shareholder  approval of
poison pills.  In recent years,  various  companies  have been willing to redeem
existing poison pills or seek  shareholder  approval for their poison pill. This
includes Columbia/HCA, McDermott International and Bausch & Lomb. I believe that
our company should follow suit and allow shareholder participation.

                        Shareholder Vote on Poison Pills
                                    Yes on 4


The affirmative vote of a majority of the votes cast at the meeting is required
for approval of this proposal.

THE BOARD OF DIRECTORS WILL OPPOSE THIS PROPOSAL IF IT IS INTRODUCED AT THE 2003
ANNUAL  MEETING AND  RECOMMENDS A VOTE AGAINST THIS  PROPOSAL FOR THE  FOLLOWING
REASONS:


                                       25



The Board of Directors Statement in Opposition

KeySpan's Board of Directors  unanimously  recommends that the shareholders vote
against Mr. Rossi's proposal. In 1999, after carefully considering its fiduciary
duties to  shareholders  and after  consultation  with outside legal counsel and
financial  advisors,  the Board adopted the Shareholder  Rights Plan or a poison
pill (described in this Proxy Statement  under the caption  "Shareholder  Rights
Plan") in order to protect KeySpan's  shareholders against hostile takeovers and
inadequate  offers and to ensure that each  shareholder is treated fairly in any
transaction involving an acquisition of control of the Company.

The purpose of the  Shareholder  Rights Plan or poison pill is to strengthen the
Board of  Directors'  ability,  in the exercise of their  fiduciary  duties,  by
forcing any would be acquirer to negotiate  directly with the Board of Directors
in order to preserve and maximize the Company's  value for all  shareholders.  A
major  function  of the  Shareholder  Rights  Plan or poison pill is to give the
Board of  Directors  a  greater  period  of time  within  which it can  properly
evaluate an acquisition offer to determine whether it reflects the full value of
the Company and is fair to all shareholders, and if not, to reject such offer or
to seek an alternative that meets these criteria.  While the Shareholder  Rights
Plan or poison  pill does not  prevent  or  inhibit  the  Company  from  being a
takeover target, it can assist the Board of Directors in delivering the greatest
value to shareholders in the event that it is a takeover target. The Shareholder
Rights Plan or poison pill serves as an important  bargaining tool for the Board
to negotiate a transaction with any potential  acquirer,  and if the shareholder
proposal is adopted it could result in a severe impediment in the ability of the
Board of  Director's to use a poison pill in the future when  circumstances  may
arise and warrant such use. The  overriding  objective of the Board of Directors
in  adopting  the  Shareholder  Rights  Plan  was,  and  continues  to  be,  the
preservation and maximization of value for all shareholders.

Numerous  other  companies,  in addition  to KeySpan,  believe it is in the best
interest of their shareholders to adopt a poison pill.  According to an Investor
Responsibility  Research ("IRRC") report issued in February 2003, 60% of S&P 500
companies have adopted a shareholder rights plans or another form of poison pill
as of the end of 2002,  up  slightly  from 59.6% in 2001 and 59.1% at the end of
2000.  The economic  benefits of poison pills was also noted in the IRRC report,
which stated that evidence is  increasingly  strong that  companies  with poison
pills in place generally  received  higher premiums in takeover  situations than
those that do not.

The  Board of  Directors  believes  that the  adoption  and  maintenance  of the
Shareholder  Rights  Plan or  poison  pill is in  accord  with the  scope of its
responsibilities  under New York law to manage and direct the  management of the
Company  and is sound  corporate  governance.  The  proposal  does  not  address
KeySpan's  high  corporate  governance  standards and its  commitment to enhance
shareholder   value.   The  Board  of  Directors   believes  that  it  is  their
responsibilities,  as the elected representatives of the shareholders, to ensure
that  KeySpan  continues  to make every  effort to apply best  practices  to its
corporate   governance   policies  and   procedures   for  the  benefit  of  all
shareholders,  and believes  that the  existence of a poison pill is  consistent
with this objective.  We believe that it is ill advised for corporate governance
matters to be decided in the  abstract,  when the  decision  could  obligate the
Company to pursue a course of action in the future without allowing the Board to
engage in a thoughtful  analysis of an  acquisition  offer,  given the facts and
circumstances at the time. In fact,  limiting the Company's freedom of action in
the future runs directly  counter to the fiduciary  standards  that the Board is
obligated to uphold.

The Board of Directors' commitment has always been, and always will be, to serve
the best interest of our  shareholders and believes that  implementation  of Mr.
Rossi's proposal would not achieve the results sought,  but instead could have a
damaging  effect on the interests of KeySpan.  WE URGE THE  SHAREHOLDERS TO VOTE
AGAINST THIS PROPOSAL.

Proxies  solicited  by the  Board  of  Directors  will be so  voted  unless  the
shareholder otherwise specifies.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE AGAINST THIS PROPOSAL.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Transactions with Management and Others

John J. Bishar,  Jr. was elected  Senior Vice  President and General  Counsel of
KeySpan,  effective  November  1, 2002.  Prior to such  date,  he was a managing
partner  of the law firm of  Cullen  and  Dykman  LLP.  During  2002,  this firm
represented KeySpan in a variety of general and specific matters. The total fees
paid to this firm during 2002 were approximately $4,058,730.

Involvement in Certain Legal Proceedings

In May 2000,  ContiFinancial  Corporation  ("ContiFinancial")  filed a voluntary
petition  for relief  under the  provisions  of Chapter 11 of the United  States
Bankruptcy  Code.  At the time of such  filing,  Alan H.  Fishman was serving as
President  and Chief  Executive  Officer  and James L.  Larocca was serving as a
director of ContiFinancial.

Directors and Officers Liability Insurance and Indemnity

KeySpan has director and officer ("D&O") liability  insurance for the purpose of
reimbursing the Company when it has indemnified its directors and officers.  D&O
liability  insurance  also provides  direct  payment to KeySpan's  directors and
officers under certain  circumstances  when KeySpan has not previously  provided
indemnification.  KeySpan also has liability  insurance which provides fiduciary
coverage for KeySpan,  its  directors,  officers and  employees  for any alleged
breach of fiduciary duty under the Employee  Retirement Income Security Act. The
D&O and fiduciary liability insurances were purchased from Associated Electric &
Gas Insurance  Services,  Energy Insurance Mutual Ltd.,  Zurich Insurance Group,
Federal Insurance  Company,  The Hartford and STARR Excess for a one-year period
commencing  May 28, 2002 at a total cost of  $2,655,099.  The  Company  plans on
renewing  its D&O  liability  and  fiduciary  insurances  for a one-year  period
commencing May 28, 2003.

Shareholder Rights Plan

On March  30,  1999,  the Board of  Directors  entered  into a Rights  Agreement
pursuant to which one preferred  stock  purchase  right (a "Right") per share of
Common  Stock was  distributed  as a dividend to  shareholders  of record on the
close of business on April 14, 1999. Each Right, when exercisable,  will entitle
the  holder  thereof  to  purchase  one one-  hundredth  of a share of  Series D
Preferred  Stock at a price of $95.00 per share.  The Rights will be exercisable
only if a person or a group  acquires 20% or more of the  outstanding  shares of
Common Stock of the Company or announces a tender offer following which it would
hold 20% or more of such  outstanding  Common Stock of the  Company.  The Rights
entitle the holders,  other than the acquiring  person, to purchase Common Stock
having a  market  value of two  times  the  exercise  price  of the  Right.  If,
following  the  acquisition  by a person  or  group of 20% or more of  KeySpan's
outstanding  shares of Common Stock,  KeySpan were acquired in a merger or other
business  combination,  each Right would be  exercisable  for that number of the
acquiring  company's  shares of common  stock having a market value of two times
the exercise price of the Right.  Subject to the terms of the Rights  Agreement,
KeySpan  may  redeem  the  Rights at $.01 per  Right at any time  until ten days
following  the  occurrence  of  an  event  that  causes  the  Rights  to  become
exercisable for Common Stock. The Rights expire in 2009.

The foregoing description of the Rights Agreement and of the Rights is qualified
in its entirety by the terms of the Rights  Agreement,  dated March 30, 1999, by
and  between  KeySpan  and the  Rights  Agent,  a copy of which  was filed as an
exhibit to KeySpan's Report on Form 8-K dated March 30, 1999.

Legal Proceedings

KeySpan has been  cooperating  in  preliminary  inquiries  regarding  trading in
KeySpan  Corporation  stock by individual  officers of KeySpan prior to the July
17, 2001  announcement  that  KeySpan was taking a special  charge in its Energy
Services  business and  otherwise  reducing its 2001  earnings  forecast.  These
inquiries are being conducted by the U.S.  Attorney's Office,  Southern District
of New York and the SEC.




                                       27





As part of its  continuing  inquiry,  on March 5, 2002,  the SEC issued a formal
order of investigation, pursuant to which it will review the trading activity of
certain company  insiders from May 1, 2001 to the present,  as well as KeySpan's
compliance  with its  reporting  rules and  regulations,  generally,  during the
period following the acquisition of the Roy Kay companies  through the July 17th
announcement.

Furthermore, KeySpan and certain of its officers and directors are defendants in
a number of class action  lawsuits filed in the United States District Court for
the  Eastern  District  of New York  after  the July  17th  announcement.  These
lawsuits allege,  among other things,  violations of Sections 10(b) and 20(a) of
the Securities  Exchange Act of 1934, as amended ("Exchange Act"), in connection
with  disclosures  relating  to or  following  the  acquisition  of the  Roy Kay
companies by KeySpan Services,  Inc., a KeySpan  subsidiary and the announcement
of the agreement to acquire Eastern Enterprises and EnergyNorth, Inc. In October
2001,  shareholder's derivative actions were commenced in the same court against
certain  officers  and  directors  of KeySpan,  alleging,  among  other  things,
breaches of fiduciary duty,  violations of the New York Business Corporation Law
and  violations of Section  20(a) of the Exchange  Act. Each of the  proceedings
seek monetary damages in an unspecified amount. We filed a motion to dismiss the
class  action  lawsuits.  On March 18,  2003,  the court  granted  our motion to
dismiss.  The court's order dismissed  certain class  allegations with prejudice
but provided the  plaintiffs a final  opportunity  to file an amended  complaint
concerning the remaining allegations.

Deadline For Shareholder Proposals

Shareholder  proposals  for the 2004  Annual  Meeting  must be  received  by the
Corporate  Secretary at KeySpan's  principal  executive  office at One MetroTech
Center,  Brooklyn,  New York  11201-3850,  Attention:  Corporate  Secretary,  by
December 1, 2003, to be considered by the Company for possible  inclusion in the
proxy materials for the 2004 Annual Meeting.

In addition, all shareholder proposals or nominations for election of a director
for the 2004 Annual Meeting must be submitted to the Company in accordance  with
Section 2.7 of the Company's  By-Laws not less than 60 nor more than 90 calendar
days in advance of the anniversary date of the 2003 Annual Meeting.

Additional Information

KeySpan's  Annual Report for the period ended  December 31, 2002 is being mailed
to shareholders on or about the date of this Proxy  Statement.  KeySpan files an
Annual Report on Form 10-K with the SEC which  includes  additional  information
concerning  KeySpan and its  operations.  The Company's  Annual Report or Annual
Report on Form 10-K,  except for  exhibits,  will be furnished at no cost to any
shareholder upon written request to: Corporate  Secretary,  KeySpan Corporation,
One  MetroTech  Center,  Brooklyn,  New York  11201- 3850 or can be found on the
Investor      Relations      section      of     the      Company's      website
(http://www.keyspanenergy.com).

Compliance With Section 16(a) of the Exchange Act

Section  16(a) of the  Exchange  Act  requires  KeySpan's  directors,  executive
officers and persons who own more than ten percent  (10%) of a registered  class
of  KeySpan's  equity  securities  to file  with  the  SEC  initial  reports  of
beneficial  ownership and reports of changes in  beneficial  ownership of Common
Stock and other equity securities of KeySpan. Executive officers,  directors and
greater than ten percent (10%)  shareholders  are required by SEC  regulation to
furnish KeySpan with copies of all Section 16(a) forms which they file.

To  KeySpan's  knowledge,  based  solely on review of  information  furnished to
KeySpan, reports filed through KeySpan and representations that no other reports
were  required,  all  Section  16(a)  filing  requirements   applicable  to  its
directors,  executive  officers  and greater than ten percent  (10%)  beneficial
owners were  complied  with during the  twelve-month  period ended  December 31,
2002,  except that certain  transactions  concerning  the  acquisition of Common
Stock equivalents  pursuant to the Directors' Deferred  Compensation Plan should
have been reported on Form 4 reports for all of our non-employee directors,  but
were  reported  on a  delinquent  basis on Form 5 reports  for the period  ended
December 31, 2002. Therefore, the Form 5 report filed for Andrea S. Christensen,
Donald H. Elliott,  Alan H. Fishman,  J. Atwood Ives,  James R. Jones,  James L.
Larocca,  Stephen W. McKessy,  Edward D. Miller and Edward Travaglianti included
delinquent Form 4 disclosures.



                                       28



Method and Cost of Solicitation of Proxies

The proxies being solicited hereby are being solicited by the Board of Directors
of the Company.  The costs of  soliciting  proxies will be borne by the Company.
The Company has retained D.F. King & Co., Inc., to aid in the solicitation.  For
these  services,  the  Company  will pay a fee of $12,500 and  reimburse  it for
certain out-of-pocket  disbursements and expenses. In addition to the use of the
mails, proxies may be solicited personally, by telephone or through the Internet
by  KeySpan  directors,   officers,  employees  and  agents  for  no  additional
compensation.  In addition,  KeySpan will reimburse  brokers,  bank nominees and
other  institutional  holders for their  reasonable  out-of- pocket  expenses in
forwarding  proxy  materials to the  beneficial  owners of the Company's  Common
Stock.

Disclosure of "Broker Non-Votes" And Abstentions

SEC rules provide that specifically  designated blank spaces are provided on the
proxy card for shareholders to mark if they wish either to withhold authority to
vote for one or more  nominees  for director or to abstain on one or more of the
proposals.  Votes withheld in connection with the election of one or more of the
nominees  for  director  will not be counted  as votes cast for or against  such
individuals. With respect to the proposal relating to the selection of auditors,
the amendment to the Employee  Discount Stock Purchase Plan and the  shareholder
proposal on poison pills,  abstentions are not counted in determining the number
of votes cast in connection  with these  proposals since New York law requires a
majority  of only those votes cast "for" or  "against"  approval,  while  broker
non-votes  are  treated  as  shares  not  entitled  to vote,  thus  giving  both
abstentions and non-votes no effect.  All  abstentions and broker  non-votes are
counted towards the establishment of a quorum.

Confidential Voting

KeySpan has adopted a policy to the effect that all proxy  (voting  instruction)
cards,  ballots and vote  tabulations  which identify the  particular  vote of a
shareholder  are to be kept secret from  KeySpan,  its  directors,  officers and
employees.  Accordingly,  proxy cards are returned in envelopes addressed to the
tabulator,   EquiServe,   which  receives  and  tabulates  the  proxies  and  is
independent  of KeySpan.  The final  tabulation  is inspected by  inspectors  of
election  who also are  independent  of KeySpan,  its  directors,  officers  and
employees.  The identity and vote of any  shareholder  shall not be disclosed to
KeySpan, its directors, officers or employees, nor to any third party except (i)
to allow the  independent  inspectors  of election to certify the results of the
vote to KeySpan,  its directors,  officers and  employees;  (ii) as necessary to
meet applicable legal requirements and to assert or defend claims for or against
KeySpan; (iii) in the event of a proxy solicitation based on an opposition proxy
statement  filed, or required to be filed,  with the SEC; or (iv) in the event a
shareholder has made a written comment on such form of proxy.

Other Matters

As of the date of this Proxy  Statement,  KeySpan knows of no business that will
be presented for consideration at the Annual Meeting of Shareholders  other than
the proposals  discussed  above.  If any matter is properly  brought  before the
meeting for action by the shareholders,  proxies in the form returned to KeySpan
will be voted in accordance  with the  recommendation  of the Board of Directors
or, in the absence of such a recommendation,  in accordance with the judgment of
the proxy holder.

                               KEYSPAN CORPORATION

                         CORPORATE GOVERNANCE GUIDELINES
                    (Amended and Restated September 26, 2002)

BOARD OF DIRECTORS

Size and Composition of the Board
- ---------------------------------

The Board shall consist of a number of directors  such that the  Corporation  is
effectively managed. The number of directors shall be fixed from time to time by
the Board and  recorded  in the  minutes  of the  Corporation.  The Board  shall
consist of a majority  of members  who are deemed to be  independent.  The Chief
Executive Officer will also be a member of the Board.

Director Independence
- ---------------------

The  independence  of directors  shall be  determined  by the Board of Directors
under the rules of the New York Stock Exchange, Inc. and the Sarbanes-Oxley Act.
The directors shall complete and submit an annual  statement on Ethical Business
Conduct to identify and assess  relationships  they may have with third  parties
(including vendors,  service providers,  competitors,  etc.) that may impact the
Corporation and could be construed as compromising the director's independence.

Board Membership of Former Executive Officers
- ---------------------------------------------

The Board of  Directors  shall not, as a general  rule,  have  former  executive
employees  serving on the Board.  It is assumed that  retiring  executives  will
tender  their   resignations   as  officers  and   directors,   if   applicable,
simultaneously. The Board may, at its discretion, invite a retiring executive to
remain a director.  To be considered  "independent," the retiring executive must
satisfy the "cooling-off" period required by the New York Stock Exchange, Inc.

Board Performance Evaluation
- ----------------------------

The Board shall  annually  review its  performance.  The Board shall measure its
results against  appropriate  criteria defined by the Board, in conjunction with
the  recommendations  of the C&N Committee.  As part of this review, the outside
directors may meet independently to assess the Board's performance.

Director Compensation Review
- ----------------------------

The Corporate  Secretary  shall  prepare,  annually,  a  comprehensive  industry
analysis of director's compensation and benefits and submit such findings to the
Chief Executive Officer for review, who will then submit a recommendation to the
Compensation   and   Nominating   Committee  for  review  and   approval.   Such
recommendation  will then be forwarded to the full Board for  consideration  and
formal vote.

Board Membership Criteria
- -------------------------

The Compensation and Nominating  Committee and the Chief Executive Officer shall
be responsible for determining the qualifications of director  candidates in the
context of the current composition of the Board.

New Director Candidates Selection
- ---------------------------------

It shall be the  responsibility  of the Chief  Executive  Officer in conjunction
with the  Compensation  &  Nominating  Committee  to  recommend  to the Board of
Directors  nominees  to fill  Board  vacancies  and to  replace  retiring  Board
members. The Board of Directors shall elect candidates to the Board.




                                       A-1



Invitations to Director Candidates
- ----------------------------------

An invitation  to join the Board shall be  communicated  by the Chief  Executive
Officer on behalf of the entire Board.

Director's Change in Present Job Responsibilities
- -------------------------------------------------

Individual directors who experience changes in employment, careers, affiliations
with  organizations or other matters,  which may affect the Corporation,  have a
duty to advise the Board of such  changes or  appointment,  as  applicable.  The
specific   circumstances  will  be  assessed  to  determine  if  the  director's
resignation from the Board should be requested.

Retirement Age
- --------------

As a general rule,  directors  shall retire on the date of the annual meeting of
shareholders following the date of their 70th birthday.

Term Limits
- -----------

There  shall  be no term  limits  for  directors,  who  may  serve  until  their
retirement  age.  The  Compensation   and  Nominating   Committee  will  propose
candidates for election or re-election at the annual meeting of shareholders.  A
review of each  director's  service on the Board will be conducted prior to such
nomination.

Director Contact with the Corporation's Constituencies
- ------------------------------------------------------

Communications  with  parties  external to the  Corporation  (including  but not
limited to shareholders,  accountants,  the media, attorneys,  vendors,  service
providers,  etc.) shall be the  responsibility of the Chief Executive Officer or
delegated  by the  Chief  Executive  Officer  to  the  appropriate  area  of the
Corporation. The directors will be consulted from time to time for their advice,
as the Chief Executive Officer so determines.


MEETINGS OF THE BOARD OF DIRECTORS

Selection of Meeting Agenda Items
- ---------------------------------

The Chairman and Chief  Executive  Officer  shall  establish  the agenda for the
Board meetings. Any director may request inclusion of an item on the agenda. The
Chairman and Chief  Executive  Officer may annually  distribute to the Board the
proposed  agenda items,  along with the schedule of meetings,  for the following
year.

Advance Distribution of Board Meeting Materials
- -----------------------------------------------

The  Corporate  Secretary  shall  distribute  to  the  directors  all  materials
necessary to conduct an effective meeting of the Board of Directors prior to the
meeting.

Regular Attendance of Non-Directors at Board Meetings
- -----------------------------------------------------

At the  invitation  and approval of the Chief  Executive  Officer or a director,
other non-directors, may attend or give presentations before the Board.

Strategy Sessions
- -----------------

The Board of Directors shall meet annually,  generally at an off-site  location,
to review with  executive  management the  Corporation's  strategic plan and its
long range goals and direction.

Executive Sessions
- ------------------

The outside directors and the Chief Executive Officer shall convene in executive
session  as often as is  appropriate,  usually  as part of  regularly  scheduled
meetings of the Board of Directors.  Executive  sessions may be requested by the
outside  directors,  as well as the Chief Executive  Officer.  In addition,  the
outside directors of the Board shall meet at least quarterly,  without the Chief
Executive  Officer  or any other  inside  director,  to  discuss  any  matter or
recommend any action as the directors  shall deem advisable  consistent with the
powers of the full  Board.  Members of the  Executive  Committee  shall serve as
presiding directors of these meetings on a rotating basis.

and Nominating, and the Corporate Responsibility and Governance Committees.

Committee Meeting Frequency and Length
- --------------------------------------

The committee chairman, in consultation with committee members,  shall determine
the  frequency  and  length of  committee  meetings.  There will be at least two

                      (Amended and Restated March 6, 2003)


Purpose and Authority
- ---------------------

The purpose of the Audit Committee is to:

A.   Provide   assistance   to  the  Board  of  Directors  in   fulfilling   its
     responsibility to the shareholders,  potential  shareholders and investment

B.   Prepare all reports  required  to be included in the  corporation's  annual
     proxy  statement,  pursuant to and in accordance with applicable  rules and

The Committee is designated by the Board of Directors and receives its authority
from the Board of  Directors  to whom it  reports.  The Board has  vested in the
Committee  the  authority  to carry  out the  responsibilities  as noted in this
Charter, and any other duties which the Committee deems necessary to fulfill its
obligations  to the  Board  of  Directors,  shareholders  and  customers  of the
Corporation.  To such end, the Committee is authorized to select,  retain and/or
replace, as needed,  consultants to provide independent advice to the Committee.
In that  connection,  in the  event the  Committee  retains  a  consultant,  the
Committee  shall have the sole authority to approve such  consultant's  fees and
other retention terms.

Membership

          committee  of  more  than  three  public   companies,   including  the
          Corporation,  unless the Board of Directors (i)  determines  that such

          effectively   serve  on  the   Committee  and  (ii)   discloses   such
          determination in the annual proxy statement.



                                       C-1





          o    Financial Literacy and Expertise

               All  members of the  Committee  shall have a working  familiarity

               familiarity   within  a  reasonable   period  after  his  or  her
               appointment) and at least one member must be a "financial expert"
               under the requirements of the Sarbanes-Oxley Act of 2002.

Chairman
- --------

Unless a Chairman is elected by the full Board of Directors,  the members of the

agendas for Committee meetings.

Independent Auditor
- -------------------

The Committee shall retain and terminate the independent auditor,  oversee their
work and approve all audit  engagement fees and terms.  The independent  auditor
shall be informed that it reports directly to the Audit Committee.

With  respect  to  the  work  of  the  independent  auditor,  the  Committee  is
responsible for (i) reviewing the scope of the audit,  (ii) approving the nature
and  cost of all  audit  and  non-audit  services  (non-audit  services  must be
approved prior to commencement of the services),  (iii) monitoring the auditor's
performance,  (iv) assuring that the auditor is  independent,  and (v) resolving
any  disagreement   between  management  and  the  auditor  regarding  financial
reporting,  for the purpose of  preparing  or issuing an audit report or related
work.

The Committee shall inquire  regularly of the  independent  auditor to ascertain
that it is receiving the full  cooperation of management,  that all  information
desired  is  provided  freely,  that  there are no  material  weaknesses  in the
internal  control  structure  and that no material  fraud was  uncovered  in the
course of its work and that management is diligent in conducting its business in
accordance with the highest ethical standards.

The Committee shall  periodically meet separately with the independent  auditors
to discuss any matters that the Committee or the  independent  auditors  believe
would be appropriate to discuss privately. In addition, the Committee shall meet
with  the   independent   auditors  and  management   quarterly  to  review  the
corporation's financial statements, and annual and quarterly reports required to
be filed with the SEC.

The  Committee  shall  approve in advance any audit or non-audit  engagement  or
relationship  between the corporation and the independent  auditors,  other than
"prohibited  non-auditing  services".  The  Committee  hereby  delegates  to the
Chairman  of the  Committee  the  authority  to approve in advance  all audit or
non-audit  services to be provided by the  independent  auditor so long as it is
presented to the full Committee at a later time.

The following shall be "prohibited  non-auditing  services":  (i) bookkeeping or
other services related to the accounting records or financial  statements of the
audit client;  (ii) financial  information  systems  design and  implementation;
(iii) appraisal or valuation services,  providing fairness opinions or preparing
contribution-in-kind  reports;  (iv)  actuarial  services;  (v)  internal  audit
outsourcing services; (vi) management functions or human resources; (vii) broker
or dealer,  investment  adviser or  investment  banking  services;  (viii) legal
services and expert services  unrelated to the audit; and (ix) any other service
that the Public Company Accounting Oversight Board prohibits through regulation.

Notwithstanding  the  foregoing,  pre-approval  is not necessary for minor audit
services if: (i) the aggregate amount of all such non-audit services provided to
the  corporation  constitutes  not more than five percent of the total amount of
revenues paid by the  corporation to its auditor during the fiscal year in which
the non-audit  services are provided;  (ii) such services were not recognized by
the  Corporation  at the time of the  engagement to be non-audit  services;  and
(iii) such  services are promptly  brought to the attention of the Committee and
approved  prior to the  completion of the audit by the Committee or its Chairman
pursuant to delegated authority.



                                       C-2





The Committee shall review, at least annually,  the qualifications,  performance
and  independence  of the  independent  auditor.  In  conducting  its review and
evaluation, the Committee shall:

     (a)  Obtain and review a report by the  corporation's  independent  auditor
     describing:  (i) the auditing firm's internal  quality-control  procedures;
     (ii) any  material  issues  raised  by the most  recent  internal  quality-
     control review,  or peer review, of the auditing firm, or by any inquiry or
     investigation  by  governmental  or  professional  authorities,   with  the
     preceding five years, respecting one or more independent audits carried out
     by the auditing firm, and any steps taken to deal with any such issues; and
     (iii) to assess the auditor's  independence,  all relationships between the
     independent auditor and the Corporation;

     (b)  Ensure the  rotation  of the lead  audit  partner at least  every five
     years,  and consider  whether there should be regular rotation of the audit
     firm itself;

     (c) Confirm with any independent auditor retained to provide audit services
     for any fiscal year that the lead (or  coordinating)  audit partner (having
     primary responsibility for the audit), or the audit partner responsible for
     reviewing the audit,  has not performed  audit services for the corporation
     in each of the five previous fiscal years of that corporation; and

     (d) Take into  account the  opinions of  management  and the  corporation's
     internal  auditors (or other  personnel  responsible for the internal audit
     function).

Internal Auditing Division
- --------------------------

The Vice President & General  Auditor (a corporate  officer) is in charge of the
Internal  Auditing  Division  and reports  directly  to the Board of  Directors,
functionally   to  the  Audit   Committee   of  the  Board  of   Directors   and
administratively to the Executive Vice President, Administration and Compliance.

Each year,  the General  Auditor will submit an Audit Plan to the  Committee for
approval.  Thereafter,  the General Auditor will keep the Committee  informed on
the progress of the Plan's implementation,  and twice a year will submit written
reports on such  progress  and on the results of his  reviews  and  management's
response to any problems or weaknesses in controls noted.

The  Committee  shall review the Charter of the Internal  Auditing  Division and
approve  any  changes  thereto.  It shall  also  ascertain  that  the  resources
allocated  to the  Internal  Auditing  function  are  sufficient  to ensure that
adequate internal audit review is being performed in the Corporation.

The  Committee  may meet  privately  with  the  General  Auditor  at each of its
meetings and at any other time at the General  Auditor's  request  without prior
communication with management.

The General Auditor shall not be appointed or removed by management  without the
concurrence of the Committee.

The Committee may provide special  assignments to the General Auditor to perform
reviews in selected areas of its interest or concern.

Financial Statements and Internal Accounting Control

The Committee shall review with management and the independent  auditor prior to
public  dissemination the Corporation's  annual audited financial statements and
quarterly financial  statements,  including the Corporation's  disclosures under
"Management's  Discussion  and  Analysis of Financial  Condition  and Results of
Operations."  The review should  include  discussions  with  management  and the
independent  public  accountants  of  significant  issues  regarding  accounting
principles,  practices and judgements,  including those matters set forth in SAS
No. 61.

As part of its  quarterly  review,  the  independent  auditor  will discuss with
management  any  judgmental  areas,  adjustments,  disclosures  and all material
changes in accounting  principles.  Management will report to the Committee,  in
writing,  any  material  items  or  discussions   resulting  from  such  review.
Management  will  also  provide  the  Committee,  upon  issuance,  copies of the




                                       C-3



quarterly reports to shareholders and related filings with the SEC. In addition,
the  Committee,  or  at  the  minimum  its  Chairman,  should  communicate  with
management and the independent auditor on a quarterly basis (prior to the filing
of the Corporation's 10-Q), to review the Corporation's financial statements and
significant findings based upon the independent auditor's review procedures. Any
significant  changes to the  Corporation's  accounting  principles and any items
required to be communicated by the independent public accountants, in accordance
with SAS No. 61, should also be discussed.

The Committee  shall also review and discuss with management and the independent
auditor,  as  appropriate,  the  Corporation's  earnings press releases  (paying
attention to the use of any "pro forma" or "adjusted" non-GAAP information),  as
well as financial  information  and earnings  guidance  provided to analysts and
rating  agencies.  The  Committee's  discussion in this regard may be general in
nature  (i.e.,  discussion of the types of  information  to be disclosed and the
type of  presentation  to be made) and need not take  place in  advance  of each
earnings  release or each instance in which the Corporation may provide earnings
guidance.

At least once during the year, the Committee  shall obtain  assurances  from the
General Auditor and management that the system of internal  controls is adequate
and functional.

The Committee shall also perform any functions required to be performed by it or
otherwise   appropriate   under  applicable  law,  rules  or  regulations,   the
Corporation's by-laws and the resolutions or directives of the Board,  including
review  of  any  certification  required  to  be  reviewed  in  accordance  with
applicable law or regulations of the SEC.


Financial Reporting Process
- ---------------------------

In  consultation  with the  independent  auditor,  management  and the  internal
auditors,  the  Committee  shall  review  the  integrity  of  the  Corporation's
financial reporting processes,  both internal and external.  In this connection,
the Committee  should  obtain and discuss with  management  and the  independent
auditor reports from management and the independent  auditor regarding:  (i) all
critical accounting  policies and practices to be used by the Corporation;  (ii)
analyses  prepared by management  and/or the  independent  auditor setting forth
significant financial reporting issues and judgments made in connection with the
preparation of the financial statements, including all alternative treatments of
financial  information within generally accepted accounting principles that have
been discussed with the Corporation's  management,  the ramifications of the use
of alternative  disclosures and treatments,  and the treatment  preferred by the
independent  auditor;  (iii) major issues  regarding  accounting  principles and
financial  statement  presentations , including any  significant  changes in the
Corporation's  selection or  application  of accounting  principles;  (iv) major
issues  as to the  adequacy  of the  Corporation's  internal  controls  and  any
specific audit steps adopted in light of material control deficiencies;  and (v)
any other material written  communications  between the independent  auditor and
the Corporation's management.

The Committee shall review  periodically the effect of regulatory and accounting
initiatives,   as  well  as  off-balance  sheet  structures,  on  the  financial
statements of the Corporation.

The  Committee  shall also  review  with the  independent  auditor (i) any audit
problems or other  difficulties  encountered by the auditor in the course of the
audit  process,  including  any  restrictions  on the  scope of the  independent
auditor's activities or on access to requested information,  and any significant
disagreements  with management and (ii)  management's  response to such matters.
Without  excluding  other  possibilities,  the  Committee  shall review with the
independent  auditor (i) any accounting  adjustments that were noted or proposed
by the  auditor  but  were  "passed"  (as  immaterial  or  otherwise),  (ii) any
communications  between  the audit  team and the audit  firm's  national  office
respecting  auditing or accounting  issues presented by the engagement and (iii)
any "management" or "internal  control" letter issued, or proposed to be issued,
by the independent auditor to the Corporation.

and policies with respect to risk assessment and risk management.  The Committee
should discuss the  Corporation's  major  financial risk exposures and the steps
management has taken to monitor and control such exposures.

Set clear hiring  policies for employees or former  employees of the independent
auditor. At a minimum,  these policies should provide that any registered public

or any person serving in an equivalent capacity for the Corporation was employed
by the registered  public  accounting firm and  participated in the audit of the

received by the Corporation regarding accounting,  internal accounting controls,
or  auditing  matters;  and  (ii)  the  confidential,  anonymous  submission  by

auditing matters.

The  Committee  shall  maintain  continuing  vigilance  for  any  procedures  or
practices which might impair the Corporation's financial and business integrity.
Annually,  the Committee will receive from the General  Auditor a written report
on compliance with ethical  business  conduct and the Public Service  Commission
agreement  and shall make  inquiries,  as  necessary,  to assure itself that the
highest standards of business conduct are being followed.

Periodically,  the Corporate  Ethics  Officer may report to the Committee on the
Corporate  Ethics Program and any  significant  events that occurred and actions
taken by management.

Once a year,  the Committee  shall review with  management  policies  respecting
expenses and perquisites.

Once a year,  the  Committee  shall  review and assess the adequacy of the Audit
Committee  Charter.  In addition,  the Committee  shall submit the charter to be
