                     PROXY STATEMENT OF KEYSPAN CORPORATION
                    ANNUAL MEETING TO BE HELD ON MAY 9, 2002


Proxies are being solicited on behalf of the Board of Directors of the Company
for use at the Annual Meeting of Shareholders on May 9, 2002, or any adjournment
thereof. This Proxy Statement is first being mailed to the shareholders of the
Company on or about April 4, 2002.


Q:   What am I voting on?
A:   Election  of ten  directors;  ratification  of  Deloitte & Touche  LLP,  as
     independent  public  accountants for the year ending December 31, 2002; 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 11, 2002
     (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.

     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.

     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.


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 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 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 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 11, 2002, the Record Date, 140,071,011
     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.


                                        1







Q:   What percentage of stock do the directors and officers own?
A:   The  directors and certain  executive  officers own  approximately  306,605
     shares, which is less than 1% of our Common Stock, as of March 1, 2002.


Q:   When are the shareholder proposals due for the 2003 Annual Meeting?
A:   Shareholder  proposals  for the 2003  Annual  Meeting  must be  received by
     KeySpan  at its  offices  at  One  MetroTech  Center,  Brooklyn,  New  York
     11201-3850,  Attention: Secretary, by December 5, 2002, to be considered by
     the Company for  possible  inclusion  in the proxy  materials  for the 2003

     election as director  for the 2003 Annual  Meeting must be submitted to the

one-year term:

Nominees for election this year are:

       .        Robert B. Catell                     .        J. Atwood Ives
       .        Andrea S. Christensen                .        James R. Jones

       .        Alan H. Fishman                      .        Edward D. Miller

Each director will hold office for one year or until their successors are duly
elected or chosen and qualified.

If any director is unable to stand for election, the Board may provide for a
lesser number of directors or designate a substitute. In the latter event,
shares represented by proxies may be voted for a substitute director. KeySpan
does not anticipate that any of the individuals listed above will be unable to
serve the full term of office to which they may be elected. The affirmative vote
of a plurality of the shares of KeySpan Common Stock cast is required for the
election of directors.

Effective May 9, 2002, both Lilyan H. Affinito and James Q. Riordan will retire,
and Vicki L. Fuller will resign, as directors of the Company.  The Board and the
Company extend their gratitude to Ms.  Affinito,  Ms. Fuller and Mr. Riordan for
their service as valued directors.

Effective March 1, 2002, Craig G. Matthews retired as a director and as vice
chairman and chief operating officer of the Company. The Board and the Company
extend their gratitude to the long and valued service Mr. Matthews provided to
the Company as a member of the Board and as an officer of the Company.

Effective December 31, 2001, George Bugliarello and Basil A. Paterson retired as
consulting directors of the Company. Messrs.  Bugliarello and Paterson were also
members of the board of directors and retired as such on December 31, 2000.  The
Board and the Company extend their gratitude to Messrs. Bugliarello and Paterson
for their service as valued directors.

Effective November 7, 2001, William C. Thompson, Jr. resigned as consulting
director of the Company after his election as Comptroller of the City of New
York. Edward Travaglianti remains as the sole consulting director of the Company
and, as such, will continue to advise and counsel the Board and any of its
committees on various matters. A consulting director does not have the right to
vote at meetings of the Board or at meetings of committees of the Board.

Finally, the Board and the Company recognize the late Richard N. Daniel for his
service as a valued director of the Company until his passing on October 25,
2001. The Board and the Company also extend their best wishes to Mr. Daniel's
family and loved ones.

In recognition of the vacancies left by Mdmes. Affinito and Fuller and Messrs.
Riordan, Matthews and Daniel, the Board has resolved to reduce and fix its size
at ten, effective May 9, 2002.

     .    Non-employee and consulting directors:

               $30,000 annual retainer;

               $1,500 meeting fee for each meeting of the Board of Directors and
               each meeting of a committee  of the Board of  Directors  attended
               (directors  attending more than one meeting on the same day shall
               be paid only one meeting fee for that day);

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

The Board of Directors has adopted the Directors' Deferred Compensation Plan to
directly align the non-employee directors' and consulting directors' financial
interest with those of the shareholders. The Directors' Deferred Compensation
Plan requires all non-employee directors and consulting directors to defer a
minimum of 50% of their cash compensation as directors or consulting directors
in exchange for Common Stock equivalents. Common Stock equivalents are valued by
utilizing the lowest of either (i) the average of the high and low price per
share of KeySpan Common Stock on the first trading day of the calendar quarter
or (ii) the average of the high and low price per share of KeySpan Common Stock
on the last trading day of the calendar quarter, in which contributions are
received. Compensation not subject to mandatory deferral into a Common Stock
equivalent account may, at the director's or consulting director's option, 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 or consulting director's Common Stock equivalent account and cash
account shall, at the director's or consulting 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
or consulting director.

Directors,  composed  of six  non-  employee  directors,  administers  KeySpan's
executive  compensation  program.  The  members of the  Committee  are Donald H.
Elliott, James R. Jones, James L. Larocca,  Stephen W. McKessy, Edward D. Miller
and James Q.  Riordan,  with Mr.  Miller  serving as  chairperson.  None of such
members  is or  has  been  an  officer  or  employee  of  KeySpan  or any of its
subsidiaries.

During 2001, the Committee met periodically throughout the year and utilized
outside consultants from the Hay Group, a national compensation consultant, to
review the compensation levels of KeySpan's officers, including the Named
Executive Officers, and to provide advice with respect to incentive compensation
plan matters. The Committee also reviews, recommends and approves changes to the
Company's compensation policies and programs for the Chief Executive Officer,
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 compensation are
submitted to the entire Board for ratification. There were no material decisions
of the Committee which were overruled or revised by the Board.

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:

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

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

     .    The incentive compensation program for executives shall strengthen the
          link of incentive  compensation  to the  achievement  of financial and
          strategic objectives which are set in advance by the Committee.

     .    In determining  executive  compensation levels for base salary, annual
          and  long-term   compensation,   the  compensation   levels  shall  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 Hay Group
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


                                       10





respect to base salary and the overall executive compensation program.

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 are determined on an annual basis. Effective January 1, 2001, the
Committee and the Board approved an increase in Mr. Catell's annual base salary
to $881,000. 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.
In determining the base salary level for the Chief Executive Officer, the
Committee has taken into consideration Mr. Catell's performance in connection
with, among other things, an increase in overall earnings per share, total
shareholder return and the implementation of the Company's acquisition growth
strategy, including the successful integration of Eastern Enterprises during
2001. Based upon an assessment of all these factors, effective January 1, 2002,
the Committee and the Board approved an increase in annual base salary for Mr.
Catell to $938,000.

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
2001, the performance measurement period included the twelve-month period from
January 1, 2001 to December 31, 2001. The awards for this period were paid in
March 2002. 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
increased return on equity, improved cash flow, improved corporate earnings
results, improved competitive position, improved customer satisfaction, improved
employee satisfaction and control of operating expenses. During 2001, a
corporate diversity incentive was introduced as a performance measure in the
Corporate Plan. Incentive awards as a percentage of cumulative salary paid in
connection with 2001 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 2001 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 2001, the Chief
Executive Officer had a target award level of 80% of cumulative paid salary with
performance criteria based upon return on equity, consolidated earnings per
share, cash flow and our diversity incentive. Based upon actual 2001 results, an
award payout of 32% of


                                       11





cumulative paid salary was approved by the Committee and paid in March 2002. The
amount reflected in the Summary Compensation table that was paid in March 2001
for performance during 2000 represented a payout of 115% of cumulative paid
salary. Upon the recommendation of the Hay Group for the year 2002, 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.

Pursuant to the Corporate Plan, commencing with the 2001 plan year, 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 and 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 number of DSUs
credited shall be determined by utilizing the lower of either (i) the average of
the high and low price per share of Common Stock on the first trading date of
the calendar quarter or (ii) the average of the high and low price per share of
KeySpan Common Stock on the last trading day of the calendar quarter, in which
the contributions are received. The DSU, 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, into a DSU
account.

Each DSU shall be in the form of an unfunded bookkeeping entry and shall
represent one full or fractional share of KeySpan Common Stock. The Company will
maintain a book entry account reflecting the DSUs purchased by each executive.
The account will be credited with dividend equivalents in the amount of any cash
dividend paid from time to time converted to a stock unit or fraction of a unit
in the executive's DSU account as of such dividend date.

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 Hay Group'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 1, 2002, approximately 12,492,085 stock options and 116,893
restricted stock grants have been awarded under the Incentive Plan.

The Incentive Plan provides for the award of incentive stock options,
non-qualified stock options, performance stock awards and restricted shares to
key employees and non-employee 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 February 13, 2001, based upon the performance of the Chief Executive Officer,
the Committee approved a grant to Mr. Catell of 267,000 non-qualified stock
options to purchase Common Stock at an exercise price of $39.50 (vesting on a
pro rata basis over a three to five-year period, depending upon Company
performance, or fully upon retirement, whichever occurs first).

Since 2001, the option award process includes 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,
with KeySpan's goal to be in the top third of those comprising the group.
Options were granted with a five-year pro rata vesting schedule, rather than the
traditional three-year pro rata vesting schedule. If, at the end of the
three-year


                                       12





performance period, KeySpan's TSR is within the top third of companies that
comprise the S&P Utility Group, 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.

On March 1, 2002, the Committee approved a grant to Mr. Catell of 372,000
non-qualified stock options and 13,295 shares of restricted stock. The options
shall vest pro rata over a three to five-year period, depending upon the
Company's performance under the TSR goals. However, 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.

Beginning in 2002, in order to further align the interests of shareholders, in
the award of restricted stock to officers, a share price performance target
shall be included in the award agreement. A four year share price target has
been established and linked to the lapse of restrictions. The minimum
restriction period is two years. If the target share price is met at any time
between years two and four, the restrictions shall lapse. However, if the target
is not achieved by the fourth year, restrictions shall not lapse until the sixth
year. In the event of retirement, the restrictions on the shares granted shall
lapse on a pro rata basis using the full months of employment from the grant
date to retirement, divided by 48 months.

During 2002, an aggregate of 2,132,800 non-qualified stock options and 74,195
shares of restricted common stock were granted to all officers as a group. The
grants of non-qualified stock options and restricted Common Stock 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 restricted
shares are directly linked to KeySpan's shareholder value. As the value of
KeySpan's Common Stock is generally considered the strongest indicator of
overall corporate performance, these awards provide a strong incentive to
participants by linking compensation to the future value of KeySpan's Common
Stock.

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 the utility industry
generally and in the energy industry specifically.

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

For purposes of the retirement plan, the final average annual compensation is
the average annual compensation for the highest five consecutive years of
earnings during the last ten years of credited service. The annual salary and
bonus for the current year for the Named Executive Officers is indicated in the
Annual Compensation columns of the Summary Compensation Table.

The number of years of credited  service for the Chief  Executive  Officer  and,
with  the  exception  of Mr.  Matthews,  each of the  Named  Executive  Officers
currently employed by the Company,  based on continued service to age 65, normal
retirement  age,  will be as follows:  R. B. Catell - 45 years,  R. J. Fani - 42
years,  W. P. Parker - 43 years and G.  Luterman - 10 years.  As a result of Mr.
Matthews'  retirement,  his actual years of credited service to the Company will
be 36 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 2001, these limits were $170,000 and $140,000,
respectively. Annual retirement benefits attributable to amounts in excess of
these limits are provided for under the Excess Benefit Plan (the "Benefit Plan")
and not under the Company's retirement plan.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

Neither Messrs. Elliott, Jones, Larocca, McKessy, Miller or Riordan 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. The agreement covers the period beginning July
31, 1998 and ending July 31, 2003. 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.

KeySpan also entered into an employment agreement on September 1, 1999 with Mr.
Craig G. Matthews relating to his services as President and Chief Operating
Officer. The agreement covered the period beginning September 1, 1999 through
August 31, 2003. The agreement was amended, effective March 2, 2001, to reflect
Mr. Matthews' promotion to Vice Chairman and Chief Operating Officer with the
terms of the amended agreement ending on March 2, 2003 or, at the option of Mr.
Matthews, on August 31, 2003. In addition to base salary, annual and long- term
incentive compensation and other employee benefits, Mr. Matthews' employment
agreement provided for severance benefits to be paid to him in the event his
employment was terminated by KeySpan without cause or if Mr. Matthews terminated
his employment for good reason. Nevertheless, as a result of his retirement
without cause, the Company will pay the accrued obligations to him without
severance benefits and he is entitled to supplemental retirement benefits
provided by the benefit plan.

KeySpan also is party to an employment agreement entered into on July 29, 1999
with Mr. Gerald Luterman relating to his services as Senior Vice President and
Chief Financial Officer. The agreement covers the period beginning July 29, 1999
and ending July 31, 2002. In addition to base salary, annual and long-term
incentive compensation and other employee benefits, Mr. Luterman'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. Luterman terminates
his employment for good reason. The severance benefits to be provided during the
severance period would include: (a) payment to Mr. Luterman in a single lump sum
of (i) all accrued obligations and (ii) the aggregate amount of salary and
annual target incentive compensation that he would have received had he remained
employed through the end of the employment period; (b) continued accrual and
vesting of benefits under the benefit plan 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. Luterman voluntarily terminates his
employment, other than for good reason, the Company shall pay the accrued
obligations to Mr. Luterman and he shall be entitled to supplemental retirement
benefits provided by the Benefit Plan. If Mr. Luterman's employment is
terminated following a "change of control" of KeySpan (as defined in the
agreement), he is eligible to receive the severance benefits provided under his
agreement as an offset, and not in addition to, any severance payments from the
Senior Executive Change of Control Severance Plan (the "Change of Control
Plan").



                                       18








Senior Executive Change of Control Severance Plan

With the exception of Mr. Catell, 48 officers of the Company and certain
subsidiaries are participants in 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 Presidents 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 1, 2002, 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, 2002. Arthur Andersen LLP ("Arthur Andersen") served as
KeySpan's independent public accountants since May 1998. On March 29, 2002,
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 past two fiscal years, and the subsequent interim period through
March 29, 2002, there has been no report on the financial statements of the
Company by Arthur Andersen which contained an adverse opinion or a disclaimer of
opinion, or was qualified or modified as to uncertainty, audit scope, or
accounting principles. During the past two fiscal years, and the subsequent
interim period through March 29, 2002, there have been 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 both Arthur Andersen and Deloitte & Touche will attend the
Annual Meeting and be available to answer shareholder questions and will have
the opportunity to make a statement if they desire to do so.

Audit Fees

Audit fees paid by the Company to Arthur Andersen for the fiscal year ended
December 31, 2001, were approximately $1,065,000 and audit related fees amounted
to approximately $874,000. Audit related services


                                       19





generally include fees for statutory audits, benefit plan audits, accounting
consultation, various attest services under professional standards, assistance
with registration statements, comfort letters and consents.




All Other Fees

All other fees paid by the Company to Arthur Andersen for the fiscal year ended
December 31, 2001, were approximately $1,260,000. Such fees generally include
tax consultation and tax services.

The Audit Committee has reviewed the nature and scope of the services provided
by Arthur Andersen and considers such to have been compatible with the
maintenance of Arthur Andersen'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 2002 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 if the additional services involve fees in excess of
$50,000.

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.


OTHER INFORMATION

Report of the Audit Committee

The Audit Committee of the Board of Directors of KeySpan is composed of six
independent, non-employee directors and operates under a written charter adopted
by the Board of Directors.

We have reviewed and discussed with management the Company's audited financial
statements as of, and for, the year ended December 31, 2001.

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 themselves 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, 2001.

Directors and Officers Liability Insurance and Indemnity

KeySpan currently has in place 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 for a one-year period commencing
May 28, 2001 at a total cost of $1,769,515. The Company will renew the D&O
liability and fiduciary insurances for a one-year period commencing May 28,
2002.


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 will be 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 or announces a tender offer following which it would hold 20% or
more of such outstanding Common Stock. 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
ten years.

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.

Notice to Shareholders of a Change of Rights Agent

EFFECTIVE JUNE 1, 2002, (THE "DISCHARGE DATE"), THE BANK OF NEW YORK WILL BE
DISCHARGED AS THE RIGHTS AGENT UNDER THE RIGHTS AGREEMENT. EFFECTIVE UPON THE
DISCHARGE DATE, KEYSPAN WILL APPOINT EQUISERVE TRUST COMPANY, N.A. TO SERVE AS
THE SUCCESSOR RIGHTS AGENT UNDER THE RIGHTS AGREEMENT.

Involvement in Certain 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 of ContiFinancial. Mr. Fishman joined
ContiFinancial in July 1999 and resigned in March 2001.

Material Litigation

KeySpan has been cooperating in preliminary inquiries regarding trading in the
Company's Common 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 Securities and Exchange Commission ("SEC"). 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 the Company's
compliance with its reporting rules and regulations, generally during the period
following the acquisition of the Roy Kay companies which are part of our energy
services business, through


                                       21





the July 17th announcement.

In addition, 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. Finally, in October 2001, a shareholder's derivative action was
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 seeks monetary damages in an unspecified amount. We
are unable to determine the outcome of these proceedings and what effect, if
any, such outcome will have on our financial condition, results of operations or
cash flows.

Deadline For Shareholder Proposals

Shareholder proposals for the 2003 Annual Meeting must be received by the
Secretary at KeySpan's principal executive office at One MetroTech Center,
Brooklyn, New York 11201-3850, Attention: Secretary, by December 5, 2002, to be
considered by the Company for possible inclusion in the proxy materials for the
2003 Annual Meeting.

In addition, all shareholder proposals or nominations for election of a director
for the 2003 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 2002 Annual Meeting.

Additional Information

KeySpan's Annual Report for the period ended December 31, 2001 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
shareholders upon written request to: Secretary, KeySpan Corporation, One
MetroTech Center, Brooklyn, New York 11201-3850.

Section 16(a) Beneficial Ownership Reporting Compliance

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,
2001, except that Donald H. Elliott reported a delinquent Form 4 transaction on
his Form 5 report and William C. Thompson, Jr. reported two delinquent Form 4
transactions on his Form 5 report. Additionally, Mr. Wallace P. Parker Jr.
reported a delinquent transaction on his current Form 5 report which should have
been reported on a Form 5 report for the period ended December 31, 2000.

Method and Cost of Solicitation of Proxies

KeySpan will bear the cost of soliciting proxies. 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.



                                       22




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 selection of auditors,
abstentions are not counted in determining the number of votes cast in
connection with this proposal, since New York State 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.
