Annual Report                 The 1999  Annual  Report,  which  is not a part of
                              the proxy solicitation material, has   been mailed

                              and  voted  at the  Annual  Meeting.  Stockholders
                              of  record  may  appoint  proxies  and  vote their

                                    Proxy Card in the envelope provided.

                               Stockholders  whose  shares  are  held by a bank,
                               broker  or  other  financial   intermediary   may

                               intermediary.

                               in the  accompanying  Proxy Statement at any time
                               prior to its exercise at the meeting.

                            PROXY STATEMENT FOR THE
                      2000 ANNUAL MEETING OF STOCKHOLDERS




                                                                  March 27, 2000

     The  accompanying  proxy is  solicited  on behalf of the Board of Directors
(the "Board") of Kerr-McGee  Corporation (the  "Company").  This Proxy Statement
and the  accompanying  form of proxy are first being mailed to  stockholders  on
March 27, 2000.

     Stockholders  of record may appoint proxies and vote their shares in one of
three ways:

1.   Via Internet pursuant to the instructions on the Proxy Card;
2.   Calling the toll-free number on the enclosed Proxy Card; or
3.   Signing,  dating  and  mailing  the  enclosed  Proxy  Card in the  envelope
     provided.

     Proxies will be voted as directed, unless revoked before the Annual Meeting
on May 9, 2000,  by the  stockholder.  Any  Stockholder  who  attends the Annual
Meeting and elects to vote in person may revoke the proxy  previously  submitted
at the meeting.  Otherwise, a Stockholder must advise the Corporate Secretary in
writing of the  revocation of the proxy.  Unless  directed  otherwise,  returned
proxies will be voted for the election of the nominees for director listed below
and on other matters as recommended by the Board of Directors.

     Under  Section  216  of  the  Delaware  General  Corporation  Law  and  the
Kerr-McGee  Corporation  ByLaws (the "ByLaws"),  a majority of the shares of the
common stock,  present in person or  represented  by proxy,  shall  constitute a
quorum  for  purposes  of the  annual  meeting.  In all  matters  other than the
election of directors, the affirmative vote of the majority of shares present in
person or represented by proxy at the annual meeting and entitled to vote on the
subject matter shall be the act of the stockholders.  Directors shall be elected
by a plurality  of the votes  present in person or  represented  by proxy at the
annual  meeting and entitled to vote on the election of  directors.  Abstentions
will have the effect of votes  against a proposal,  and broker  nonvotes have no
effect on the vote.

                               VOTING SECURITIES

     The Company's only class of voting  securities is its common stock having a
par  value of $1.00  per  share  (the  "Common  Stock"),  of  which  there  were
94,135,511 shares outstanding as of the close of business on March 10, 2000, the
record date for  stockholders  entitled to receive notice of and to vote at this
meeting.  Each share is entitled to one vote.  The number of shares  outstanding
does not include shares held in treasury, which will not be voted.

                           AGENDA FOR ANNUAL MEETING

     Three items of business  are  scheduled  for the 2000  Annual  Meeting,  as
follows:

     1.  Election of  Directors
     2.  Ratification of the appointment of Arthur Andersen LLP as the Company's
         independent public accountant
     3.  Approval of the 2000 Long Term Incentive Plan

All three of these items are discussed below.

The Board of Directors recommends you vote "FOR" each of these items.

                                   Item No. 1
                                   ----------

                             ELECTION OF DIRECTORS

     The Board of Directors has nominated Sylvia A. Earle, Martin C. Jischke and
Leroy C. Richie for election as Directors for a term expiring at the 2003 Annual
Meeting  and in each case until  their  respective  successors  are  elected and
qualified.  The nominees are currently  Directors of the Corporation whose terms
expire at the 2000 Annual Meeting.

     The Board of Directors has  currently  fixed the number of Directors at 12.
The Company's  Certificate  of  Incorporation  and ByLaws provide that Directors
shall be divided into three classes serving  staggered  three-year  terms,  with
each class to be as nearly equal in number as possible.

     None of the nominees are related to any  executive  officer of the Company,
its subsidiaries,  limited liability companies or affiliates.  All nominees have
consented to serve, and the Company has no reason to believe any nominee will be
unavailable.  Should any nominee become  unavailable for any reason, the proxies
will be voted  for a  substitute  nominee  to be named by the Board  unless  the
number of Directors constituting a full board is reduced.

     At the Annual Meeting,  the  stockholders  will vote on the election of the
nominees to the Board of Directors.  Biographical  and other  information  about
each of the nominees as well as the incumbent directors who are not standing for
reelection  is set  forth  in the  proxy  materials  beginning  on page 11 under
"Director Information."

     The Board of Directors recommends a vote "FOR" the election to the Board of
each of the nominees.

                                   Item No. 2
                                   ----------

RATIFICATION OF THE APPOINTMENT OF
INDEPENDENT PUBLIC ACCOUNTANT

     The Board of Directors has appointed  Arthur  Andersen LLP, an  independent
public accounting firm, as the Company's  independent public accountant for 2000
in accordance with the  recommendation  of the Audit Committee.  Arthur Andersen
LLP served in the same capacity for the year ended December 31, 1999.

     Representatives  of  Arthur  Andersen  LLP will be  present  at the  Annual
Meeting to make a  statement  if they desire to do so and will be  available  to
respond to appropriate questions from stockholders.

     At the annual meeting,  the  stockholders  will vote on the ratification of
the  appointment  of Arthur  Anderson LLP as independent  public  accountant for
2000.

     The  Board  of  Directors  recommends  a  vote  "FOR"  ratification  of the
appointment of Arthur Andersen LLP.

     If  the  appointment  of  Arthur  Andersen  LLP  is  not  ratified  by  the
stockholders,  if Arthur Andersen LLP ceases to act as the Company's independent
accountant,  or if the Board of  Directors  removes  Arthur  Andersen LLP as the
Company's  independent  accountant,  the Board will appoint another  independent
accounting firm. The engagement of a new independent accounting firm for periods
following  the 2001  Annual  Meeting  will be  subject  to  ratification  by the
stockholders at that meeting.

                                   Item No. 3
                                   ----------

APPROVAL OF THE 2000 LONG TERM INCENTIVE PLAN

     The Board of Directors has approved and  recommends  that the  stockholders
vote for the approval of the  Kerr-McGee  Corporation  2000 Long Term  Incentive
Plan (the "2000 Plan") to replace the 1998 Long Term  Incentive  Plan (the "1998
Plan"). The 2000 Plan adds non-employee directors to those who were eligible for
long term  incentive  compensation  under the 1998 Plan.  The Board believes the
2000 plan will enhance the Company's  ability to attract and retain  outstanding
non-employee  directors and employees.  The 2000 Plan is designed to ensure that
amounts  paid under the Plan  qualify as  performance-based  compensation  under
Section  162(m) of the Internal  Revenue Code of 1986,  as amended (the "Code"),
and the applicable regulations.

     The Board's recommendation of the 2000 Plan follows a review and evaluation
of the  Company's  existing  compensation  plans and a comparison of those plans
with  the  programs  offered  by  comparable  companies.  While  the  2000  Plan
represents, in part, a continuation of the Company's stock option program, which
has been in effect  since 1950,  it also  provides  flexibility  in the form and
payment of awards to meet changing business needs.

     If the 2000 Plan is  approved,  the current  1998 Plan will be  terminated,
except as to outstanding options and restricted stock, which will remain subject
to the terms of the 1998 Plan. There remain available for grant 1,270,868 shares
of Common Stock under the 1998 Plan.  The 2000 Plan would permit total awards up
to 2,500,000 shares of Common Stock, representing an additional 1,229,132 shares
above the number  available  under the 1998 Plan. The 2000 Plan  establishes the
following limits:

(a)  Restricted Stock to Employees                             450,000 shares

(b)  Stock Options and Restricted Stock to non-employee  directors,  but no more
     than 100,000 shares of Restricted Stock                   300,000 shares

     At the annual  meeting the  stockholders  will vote on the  approval of the
2000 Plan.

     The  Board  of  Directors  recommends  a vote  "FOR"  the  approval  of the
Kerr-McGee Corporation 2000 Long Term Incentive Plan.

                                 Summary of Plan

Term

     The 2000 Plan will be effective as of May 1, 2000,  if the Plan is approved
by the  stockholders.  The 2000 Plan will  terminate on April 30,  2010,  unless
terminated earlier by the Board of Directors.  Termination of the 2000 Plan will
not affect  grants made prior to  termination,  but grants may not be made after
termination.

Administration

     The 2000 Plan will be administered by a committee,  currently the Executive
Compensation  Committee of the Board of Directors,  of two or more  non-employee
directors  appointed  by the  Board of  Directors  to  administer  the Plan (the
"Committee").  Subject to the terms of the 2000 Plan,  and to such approvals and
other  authority  as the Board of  Directors  may reserve to itself from time to
time,  the  Committee,  consistent  with the terms of the 2000  Plan,  will have
authority  (i) to determine the employees  eligible to  participate  in the 2000
Plan,  (ii) to  determine  the form and  terms of  grants  and  awards,  and the
conditions and restrictions,  if any, subject to which grants and awards will be
made  and  become  payable  under  the 2000  Plan,  (iii)  to  adopt  rules  and
regulations  with  respect  to the  administration  of the 2000 Plan and (iv) to
amend or rescind such rules and regulations  and make such other  determinations
authorized under the 2000 Plan as the Committee deems necessary or appropriate.

Eligibility

     Employees  who  participate  in the  2000  Plan  will  be  selected  by the
Committee  from among those  employees  of the  Company,  its  subsidiaries  and
limited  liability  companies who, in the judgment of the Committee,  may have a
significant  effect on the profitability  and growth of the Company.  Currently,
the  Company   estimates   approximately  250  employees  will  be  eligible  to
participate  in the 2000 Plan.  Employees who are selected to receive one of the
forms of compensation provided for under the 2000 Plan will not automatically be
selected  to receive  another  form of  compensation  unless such  selection  is
specified by the  Committee  or provided for by the terms of the 2000 Plan.  All
non-employee directors will be eligible to participate in the Plan.

Securities Subject To The 2000 Plan

     The  number of shares of Common  Stock  which may be issued  under the 2000
Plan may not exceed  2,500,000.  No more than  450,000 of the  2,500,000  shares
available  under the 2000 Plan may be used for  grants  of  restricted  stock to
eligible  employees.  In  addition,  no more  than a  total  of  300,000  of the
2,500,000  shares under the 2000 Plan may be used for grants of restricted stock
and stock  options to  non-employee  directors,  and no more than 100,000 of the
300,000 shares available to non-employee directors may be granted in the form of
restricted  stock.  If any  stock  option  granted  pursuant  to the  2000  Plan
terminates,  expires or lapses, or any restricted shares of Common Stock granted
pursuant to the 2000 Plan are  forfeited,  any shares of Common Stock subject to
such option or restricted  stock or so forfeited  shall again be made  available
for grant  unless,  in the case of stock  options  granted  under the 2000 Plan,
related SARs have been exercised.  In the event of any increases or decreases in
the number of issued and outstanding  shares of Common Stock,  pursuant to stock
splits, mergers,  reorganizations,  recapitalizations,  stock dividends or other
event  described  under the terms of the 2000  Plan,  the  Committee  shall make
appropriate  adjustments  to the  number of shares  subject  to grants or awards
previously  made to  participants,  in the  exercise  price  per  share of stock
options previously granted to participants and in the number and kinds of shares
which may be distributed under the 2000 Plan. Appropriate adjustments shall also
be made by the Committee in the terms of SARs to reflect any change with respect
to the number of issued and outstanding shares of Common Stock.

Stock Options

     The Plan authorizes  grants of stock options to non-employee  directors and
eligible employees from time to time as determined by the Committee.  Subject to
the  provisions of the 2000 Plan, the Committee may grant options under the 2000
Plan for such  number of shares and having  such  terms as the  Committee  shall
designate; however, the maximum number of options that may be granted to any one
optionee is 150,000 per  calendar  year.  Under the terms of the 2000 Plan,  the
Committee shall specify whether or not any option is intended to be an incentive
stock option  ("Incentive Stock Option") as described in Section 422 of the Code
or a nonstatutory or nonqualified  stock option  ("Nonqualified  Stock Option").
The  aggregate  value of Common  Stock  with  respect to which  Incentive  Stock
Options are exercisable for the first time by an individual  during any calendar
year under all Company  plans may not exceed  $100,000.  Each stock option shall
have an exercise price that is not less than the fair-market value of the Common
Stock on the date the option is granted.  Nonqualified  Stock Options may not be
exercised more than ten years and one day from the date of grant,  and Incentive
Stock  Options may not be exercised  more than ten years from the date of grant.
The Committee may establish dates on which installment portions of an option may
be exercisable  during the term of the option. The Committee may also accelerate
the  time at  which an  installment  portion  of an  outstanding  option  may be
exercisable.

     Payment for shares  received upon exercise of a stock option may be made in
cash,  shares of Common Stock,  shares of Common Stock  subject to  restrictions
under the terms of the 2000 Plan,  a  combination  of the  foregoing,  through a
cashless  exercise  with a broker,  or in such  other  manner  as the  Committee
determines.

     In the event an optionee's employment is terminated by reason of disability
or retirement,  any outstanding  option that was exercisable at the time of such
optionee's  disability or retirement shall be exercisable within the period, not
to exceed four years, specified by the Committee.  In the event of an optionee's
death  while in the  employ of the  Company  or within  three  months  after the
termination of employment,  any  outstanding  option that was exercisable at the
time of the optionee's death shall be exercisable for one year thereafter by the
legal  representative of the deceased optionee's estate.  Except in the event of
an optionee's death within three months after the termination of employment,  an
optionee ceases to be an employee for any reason other than death, disability or
retirement,  any outstanding  option may not be exercised more than three months
after  the  date of such  event.  Under no  circumstances  will  any  option  be
exercisable after it has terminated or expired.

     Because the grant of awards under the 2000 Plan is at the discretion of the
Committee,  it is not  possible to indicate  what awards will be made to persons
eligible for participation in the 2000 Plan.

     No options have been granted under the 2000 Plan.

Stock Appreciation Rights

     The Plan also  authorizes  the  Committee  to affix  SARs to stock  options
either at the time the option is  granted  or at any date prior to the  option's
expiration.  SARs provide an optionee the right to surrender all or a portion of
an option and  receive  from the Company a payment,  in shares of Common  Stock,
cash or a combination  thereof,  equal to the excess of the fair-market value of
the shares of Common  Stock for which the SAR is  exercised  over the  aggregate
option  exercise  price of such shares  under the related  option at the time of
surrender.  In addition, each outstanding SAR will be automatically exercised on
the day prior to the expiration of the related option if the  fair-market  value
of the Common  Stock on such date exceeds the relevant  option  exercise  price.
SARs  are  exercisable   only  to  the  extent  that  the  related  options  are
exercisable.  The exercise of any option will result in an immediate  forfeiture
of its related SAR, and the exercise of a SAR will cause an immediate forfeiture
of its related option.

Restricted Stock

     The Committee will determine the nature and extent of the  restrictions  on
such shares, the duration of such restrictions, and any circumstance under which
restricted  shares will be forfeited.  Restricted  shares will be deposited with
the  Company  during  the  period  of any  restriction  thereon  and,  except as
otherwise  provided  by the  Committee  during any such  period of  restriction,
recipients  shall have all of the rights of a holder of Common Stock,  including
but not  limited  to voting  rights  and the  right to  receive  dividends.  The
Committee  may  establish  rules  concerning  the impact of the  termination  of
employment  (by reason of  retirement,  disability,  death or  otherwise) or the
applicability of any outstanding restrictions.

Long Term Performance Awards

     The 2000 Plan permits the Committee to grant performance awards to eligible
employees  under the 2000 Plan from time to time as determined by the Committee.
Performance  awards may include  performance units (i.e.,  award units valued by
reference  to  financial  measures  or  property  other than  Common  Stock) and
performance  shares (i.e., award amounts valued by reference to shares of Common
Stock).

     Under the terms of the 2000 Plan,  the  Committee  will  establish the time
period of not less than one year over which  performance  will be measured  (the
"Performance  Period") and the criteria to be used by the  Committee to evaluate
the Company's performance with respect to each Performance Period. Such criteria
may include  financial or operating  measures of the Company,  such as return on
equity, return on assets, return on average capital employed, earnings per share
or  other  criteria  as  established  by the  Committee,  or may be based on the
Company's  performance compared with one or more selected companies.  Payment of
earned  performance  awards may be made to participants  in cash,  Common Stock,
restricted  Common Stock,  other  property or a combination  of the foregoing as
determined by the Committee.

Amendment

     The Board may at any time  terminate or amend the 2000 Plan in any respect,
except that the Board may not,  without further  approval of the stockholders of
the  Company,  amend the 2000 Plan so as to (i) increase the number of shares of
Common Stock which may be issued under the 2000 Plan (except for  adjustments in
the number of shares permitted with respect to certain  mergers,  consolidations
or  recapitalizations  as described under "Stock Options" above) or change terms
of the 2000 Plan  relating to the  establishment  of the  exercise  prices under
options  granted,  (ii) extend the  duration  of the 2000 Plan beyond  April 30,
2010, or (iii)  increase the maximum  dollar  amount of Incentive  Stock Options
which an individual  optionee may exercise  during any calendar year beyond that
permitted  in the Code and  applicable  rules and  regulations  of the  Treasury
Department.  No amendment  or  termination  of the 2000 Plan shall,  without the
consent of the optionee or participant in the 2000 Plan,  alter or impair any of
the rights or obligations under any options or other rights theretofore  granted
such person under the 2000 Plan.

Change In Control

     In the event of a change in control,  any outstanding  options or SARs that
have not yet  vested  shall vest  effective  as of such  date,  restrictions  on
Restricted  Stock shall lapse, and participants who have previously been awarded
performance  awards shall earn no less than the participant would have earned if
the performance period terminated as of such date.

     A Change in Control means (a) a change in any two year period in a majority
of the  Incumbent  Directors of the Board of Directors of the Company as defined
in the agreement,  (b) with certain exceptions any person becomes the beneficial
owner,  directly  or  indirectly,  of 25% or more of the  Company's  outstanding
Common Stock,  (c) with certain  exceptions,  the  consummation of the merger or
consolidation of the Company with any other corporation, or (d) if a majority of
the members of the Board of Directors in office  immediately prior to a proposed
transaction determine by written resolution that such proposed  transaction,  if
taken,  will be deemed a Change in  Control  and such  proposed  transaction  is
effected.

Federal Income Tax Effects

The federal income tax consequences applicable to the Company in connection with
an Incentive Stock Option,  Nonqualified Stock Option,  SAR, restricted stock or
performance  award are  complex and depend,  in large part,  on the  surrounding
facts and  circumstances.  Under current  federal income tax laws, a participant
will  generally  recognize  income with respect to a grant of restricted  stock,
stock options, SARs or performance awards, as follows:

     (a)  Payments  in  respect  of  performance  awards.  Any cash  and/or  the
fair-market  value of any  Common  Stock  received  as  payments  in  respect of
performance  awards under the 2000 Plan will  constitute  ordinary income to the
employee  in the year in which  paid,  and the  Company  will be  entitled  to a
deduction in the same amount.

     (b) Incentive  Stock Options.  The grant of an Incentive  Stock Option will
not result in any immediate tax consequences to the Company or the optionee.  An
optionee will not realize taxable  income,  and the Company will not be entitled
to any deduction, upon the timely exercise of an Incentive Stock Option, but the
excess of the  fair-market  value of the Common Stock  acquired  over the option
price will be an item of tax preference for purposes of the alternative  minimum
tax. If the optionee  does not dispose of the Common Stock  acquired  within one
year  after its  receipt  (or  within  two years  after the date the  option was
granted),  gain or loss  realized on the  subsequent  disposition  of the Common
Stock will be treated as long-term capital gain or loss and the Company will not
be entitled  to any  deduction.  If the  optionee  disposes of the Common  Stock
acquired  less than one year after its  receipt  (or within two years  after the
option was  granted),  the optionee  will realize  ordinary  income in an amount
equal to the  lesser of (i) the  excess of the  fair-market  value of the Common
Stock acquired on the date of exercise over the exercise  price,  or (ii) if the
disposition is a taxable sale or exchange, the amount of any gain realized. Upon
such a disqualifying disposition, the Company will be entitled to a deduction in
the same  amount and at the same time as the  optionee  realizes  such  ordinary
income.  Any amount realized by the optionee in excess of the fair-market  value
of the Common  Stock on the date of  exercise  will be taxed to the  optionee as
capital gain.

     (c) Nonqualified  Stock Options.  The grant of a Nonqualified  Stock Option
will  not  result  in any  immediate  tax  consequences  to the  Company  or the
optionee.  Upon the exercise of a Nonqualified  Stock Option,  the optionee will
generally  realize ordinary income.  However,  an employee who is subject to the
restrictions  of  Section  16(b) of the  Securities  Exchange  Act of 1934  with
respect to the stock acquired will realize as ordinary income at the time of the
lapse of the restrictions an amount equal to the excess of the fair-market value
of the Common Stock at the time of such lapse over the option price,  unless the
employee  elects  to be taxed  on the  date of  exercise.  The  Company  will be
entitled to a deduction  at the same time as, and equal in amount to, the income
realized by the optionee.

     (d) Stock  Appreciation  Rights.  Upon the  excercise  of any SAR, any cash
received and the fair-market  value on the date of excercise of any Common Stock
received will  constitute  ordinary  income to the grantee.  The Company will be
entitled to a deduction in the same amount and at the same time.

     (e) Restricted Stock. A recipient generally will not realize taxable income
upon an award of restricted stock.  However, a recipient who receives restricted
stock,  either as a grant or in payment of a performance  award, will realize as
ordinary income at the time of the lapse of the  restrictions an amount equal to
the  fair-market  value of the Common Stock at the time of such lapse unless the
recipient  elects  to  realize  ordinary  income on the date of  receipt  of the
Restricted Common Stock. At the time the recipient realizes ordinary income, the
Company  will be  entitled  to deduct  the same  amount as the  ordinary  income
realized by the recipient.

     (f) Code  Section  162(m).  Payments  or  grants  under  the 2000  Plan are
intended to qualify as "qualified performance-based compensation" under the Code
and the applicable regulations.

Accounting

     During the period that SARs are outstanding,  the Company will accrue as an
expense the amount,  if any, by which the fair-market  value of the Common Stock
exceeds the exercise price of any related option.

Board of Directors Meetings, Compensation and Committees

     During 1999 the Board held six meetings. Each director attended 75% or more
of the aggregate number of meetings of the Board and the committees of the Board
on which  each such  director  served,  except  William  E.  Bradford,  David C.
Genever-Watling and Ian L. White-Thomson.

     Directors discharge their  responsibilities not only by attending Board and
committee  meetings but also through  communication  with the Chairman and other
members of management  relative to matters of mutual interest and concern to the
Company.  Board  members who are not employees of the Company are paid an annual
fee of  $30,000,  and an  additional  fee of $1,000 for each Board  meeting  and
committee meeting  attended.  Committee Chairs are paid an annual fee of $3,000.
Subject to  stockholder  approval of the 2000 Plan,  annual grants to each Board
member of restricted stock and stock options will be made each year at the first
regular  meeting  of the Board  under the  terms  specified  in the 2000 Plan as
follows:  (a) four hundred (400) shares of restricted common stock of Kerr-McGee
Corporation;  and  (b) two  thousand  (2,000)  options  to  purchase  Kerr-McGee
Corporation  common stock.  Directors  are  reimbursed  for travel  expenses and
lodging.

     Pursuant to the 2000 Plan of Deferred Compensation, any director who is not
an employee of the Company may elect to defer any cash  compensation  until such
person ceases to be a director, after which the deferred compensation,  together
with interest, will be paid in ten equal annual installments.

     Under the Stock Deferred  Compensation Plan for Non-Employee  Directors,  a
non-employee  director may elect to defer  compensation  through the purchase of
Common  Stock on a  year-by-year  basis by  notifying  the  Company on or before
December 31, of the preceding year. The stock acquired in this nonqualified plan
may not be  distributed  to the  non-employee  director until 185 days after the
participant ceases being a director.

     The Board has established and currently  maintains an Audit  Committee,  an
Executive  Compensation  Committee,  a Finance Committee, a Nominating Committee
and a Public Responsibility Committee, as standing committees.

     The Company initially established the Audit Committee in November 1973. The
Audit  Committee  continuously  has been comprised of  independent  non-employee
directors.  The Company has also begun  implementation of the necessary steps to
ensure it complies with the rules  promulgated  by the  Securities  and Exchange
Commission and New York Stock Exchange in response to the recommendations of the
Blue  Ribbon  Committee  on  Improving  the  Effectiveness  of  Corporate  Audit
Committees.  The Audit  Committee  meets with the Company's  independent  public
accountant  to review  plans for the annual audit and the results of that audit.
The Audit  Committee  makes  recommendations  to the full  Board  regarding  the
selection of the Company's  independent public  accountant.  The Audit Committee
also meets with the Vice President of Internal  Auditing to review the scope and
results of the Company's  internal  auditing  activities  and  assessment of the
system of internal  controls.  The Audit Committee  consists of five independent
non-employee directors:  David C. Genever-Watling  (Chair), William E. Bradford,
Martin C. Jischke, John J. Murphy and Leroy C. Richie.   This committee met once
during 1999.

     The Executive Compensation Committee reviews the salaries and incentive pay
awards as  recommended  by the Chief  Executive  Officer for all officers of the
Company  and  recommends  to  the  full  Board  such  changes  as  it  may  deem
appropriate.  The Executive  Compensation  Committee also administers the Annual
Incentive  Compensation  Plan,  the Long  Term  Incentive  Plan,  the  Executive
Deferred  Compensation Plan and the Supplemental  Executive Retirement Plan. The
Executive   Compensation   Committee  recommends  but  does  not  fix  the  cash
compensation of the Chief Executive Officer.  The cash compensation of the Chief
Executive  Officer is determined by the full Board.  The Executive  Compensation
Committee  consists of all 10  independent  non-employee  directors:  William E.
Bradford (Chair), Sylvia A. Earle, David C. Genever-Watling,  Martin C. Jischke,
William C. Morris, John J. Murphy, Leroy C. Richie, Matthew R. Simmons, Farah M.
Walters and Ian L. White-Thomson. This committee met three times in 1999.

     The  Finance  Committee  reviews  the annual  budget  and other  budget and
financial matters, and makes  recommendations to the full Board regarding budget
and  finance  issues.   The  Finance  Committee  consists  of  five  independent
non-employee directors: John J. Murphy (Chair), William E. Bradford,  William C.
Morris, Matthew R. Simmons and Ian L. White-Thomson.  This committee met once in
1999.

     The Nominating Committee recommends nominees to the Board of Directors. The
Nominating Committee will consider  recommendations for the position of director
submitted by stockholders in writing in accordance with the Company's ByLaws, to
the Corporate Secretary,  Kerr-McGee Corporation, P.O. Box 25861, Oklahoma City,
Oklahoma 73125. A stockholder  desiring to make a nomination  should contact the
Corporate  Secretary  to  obtain  a copy of the  ByLaws.  See  also  Stockholder
Proposals  on page 26. The  Nominating  Committee  consists of five  independent
non-employee  directors:  William C. Morris (Chair),  Sylvia A. Earle,  David C.
Genever-Watling, Matthew R. Simmons and Farah M. Walters. Luke R. Corbett serves
as an ex-officio member. This committee did not meet in 1999.

     The Public Responsibility  Committee reviews corporate governance and other
related corporate issues to develop  recommendations  to the Board of Directors.
The Public  Responsibility  Committee consists of five independent  non-employee
directors: Leroy C. Richie (Chair), Sylvia A. Earle, Martin C. Jischke, Farah M.
Walters and Ian L.  White-Thomson.  Gregory F. Pilcher  serves as an  ex-officio
member. This committee met once in 1999.

(1) The  Company  has never  granted  free-standing  Stock  Appreciation  Rights
    ("SARs")  and has not  granted  tandem SARs since  January  1991.
(2) Consists entirely of 401(k) Company  contributions  pursuant to the Employee
    Stock  Ownership  Plan  and  amounts  contributed  under  the   nonqualified
    benefits  restoration  plan.  Company contributions pursuant to the Employee
    Stock  Ownership  Plan  for  1999   were  $9,600  each to  Messrs.  Corbett,
    McDaniel,   Linehan   and   Woodward.  Mr. Crouch  received  $7,892. Amounts
    contributed  under  the nonqualified benefits  restoration  plan for 1999 on
    behalf  of   Messrs.  Corbett,  McDaniel, Linehan, Crouch and Woodward were:
    $33,450,  $10,592,  $9,796,  $7,985 and $7,915, respectively.   The  amounts
    contributed   by   the   Company   to  the  Kerr-McGee  Corporation Benefits
    Restoration  Plan  on  behalf  of  such persons are identical to the amounts
    that would have been  contributed pursuant to the  Employee  Stock Ownership
    Plan except for the Code limitations.

</TABLE>

(1) All stock  options  granted in 1999 were  nonqualified  stock  options.  The
exercise price per option is 100% of the fair-market  value of a share of Common
Stock on the date of grant.  No option expires more than ten years from the date
of  grant.  At or after  the  grant of an  option,  the  Executive  Compensation
Committee ("Committee") may, in its discretion, grant a participant a SAR. A SAR
is only  exercisable  during  the term of the  associated  option.  No SARs were
granted in 1999, nor have any been granted since 1991.  Options may also provide
that, upon a change in control,  all options and any accompanying  SARs held for
more than six months shall become  immediately  exercisable in full. A change in
control shall be deemed to have  occurred if any person  acquires 25% or more of
the outstanding Common Stock, the stockholders approve a merger or consolidation
of the Company with any other corporation,  the stockholders  approve a complete
liquidation or disposition  of all of the Company's  assets,  or a change in the
majority of the Board of  Directors,  as described in the Plan,  occurs within a
period of 24 months.

(2) The present value was computed in accordance with the  Black-Scholes  option
pricing  model,  with  assumptions  consistent  with the  Statement of Financial
Accounting  Standards No. 123,  "Accounting  for Stock-Based  Compensation,"  as
permitted  by the rules of the  Securities  and  Exchange  Commission.  Based on
Black-Scholes,  the value on January 12, 1999, was $8.76 per option. The Company
believes,  however, that it is not possible to accurately determine the value of
options  at the  time  of  grant  using  any  option  pricing  model,  including
Black-Scholes,  since any valuation depends on numerous  assumptions.  The model
assumes:  (a) an expected option term of 5.8 years,  (b) interest rate of 4.91%,
which represents the U.S. Treasury Strip Rate at the date of grant with maturity
corresponding  to the expected option term, (c) volatility of 23.27%  calculated
using monthly stock prices for the 5.8 years prior to the date of the grant, and
(d) dividends at an average annual dividend yield of 3.14%.

(1) Options/SARs are "in-the-money" if the fair-market value of the Common Stock
exceeds the exercise price. At December 31, 1999 the closing price of the Common
Stock on the New York Stock Exchange was $62.00.

Retirement Plans

     The  Company  maintains  retirement  plans  for  all  employees,  including
officers.  The following table  illustrates the pension benefits that may accrue
to executive  officers  under the Company's  retirement  plan  assuming  various
service  periods.  The table shows the estimated annual pension benefits payable
to a covered  participant at normal retirement age under the Company's qualified
defined benefit plan, as well as the nonqualified benefits restoration plan that
provides  benefits  that would  otherwise  be denied  participants  by reason of
certain Code limitations on qualified plan benefits,  based on remuneration that
is  covered  under  the  plans and years of  service  with the  Company  and its
subsidiaries:

</TABLE>

     Covered  compensation  under the  retirement  plans  consists of salary and
bonus as reflected in the Summary Compensation Table plus pretax Section 125 and
401(k) benefit  contributions  as reflected under All Other  Compensation in the
Summary  Compensation Table, based on the highest 36 consecutive months over the
previous 120 months prior to  retirement.  Amounts shown have been computed on a
straight  life annuity  basis.  Benefits  payable  under the  qualified  defined
benefit  plan are not  subject  to  offset by Social  Security  benefits.  As of
December 31, 1999, Mr. Corbett had 14 years of credited  service;  Mr. McDaniel,
15; Mr. Linehan, 14; Mr. Crouch, 25; and Mr. Woodward, 27.

     Pursuant to the Company's  Supplemental Executive Retirement Plan ("SERP"),
certain key senior  executives are eligible to receive  supplemental  retirement
benefits.  The  SERP  is a  defined  benefit  plan  and is  administered  by the
Committee. Management recommends to the Committee employees for participation in
the SERP, and the Committee then selects the  participants.  Eligible  employees
may receive  benefits under the SERP upon retirement on or after age 52, subject
to  reduction  in  benefits  prior to age 60.  Benefits  under the SERP  equal a
specified   percentage  of  an  eligible   employee's   final  average   monthly
compensation  at retirement in the form of a monthly  income for life payable as
an actuarially equivalent tax-equalized lump sum. Generally, the SERP benefit at
retirement  is  calculated  by  determining  (i) the eligible  employee's  final
average  monthly  compensation  multiplied  by a  percentage  based  on years of
Company service minus (ii) the sum of the anticipated monthly amounts payable to
the eligible  employee as a primary Social Security  benefit and monthly amounts
payable under the Company's  qualified and  nonqualified  defined benefit plans.
The SERP  provisions  establish a benefit for  employees  who were  participants
before May 3, 1994, regardless of the years of Company service.

     The percentage of final average monthly  compensation used to determine the
SERP  benefit  ranges  from  40% to 70%,  with  benefits  depending  on when the
executive  became a  participant  in the  SERP,  the age at which  the  employee
retires  and the  reason  for the  retirement.  As of  December  31,  1999,  the
estimated  lump  sum SERP  benefit  payable  upon  retirement  to the  executive
officers named in the Summary Compensation Table, assuming (i) retirement at age
60 (age 62 for Mr.  McDaniel) and (ii) salaries are  maintained at their current
level,  is: Mr. Corbett,  $4,284,741;  Mr.  McDaniel,  $2,876,590;  Mr. Linehan,
$3,133,797; Mr. Crouch, $856,717; and Mr. Woodward, $288,339.

Change in Control Arrangements

     Continuity  Agreements  between the Company and its executive  officers and
certain key employees, including Messrs. Corbett, McDaniel, Crouch and Woodward,
provide certain benefits in the event of a qualifying termination that occurs in
connection with a "change in control" of the Company.

     In the event of a qualifying  termination  of  employment  within two years
after a change in control, such executive will be entitled to receive a lump sum
cash payment equal to three times the executive's annual base salary,  bonus and
perquisites.  In  addition  the  executive  will be  entitled to any accrued but
unpaid  compensation and additional  savings plan contributions for a three-year
period plus the  present  value of lost  pension  benefits  under the  Company's
qualified  defined  benefit  pension  plans after giving effect to five years of
credit for age and service in the benefit  calculation.  The executive also will
be  entitled  to the  continuation  of group  insurance  for up to three  years,
outplacement  services,  and  acceleration of vesting of equity and equity-based
awards (unless such  acceleration  would adversely  affect  pooling-of-interests
accounting).

     If any payments and benefits made and provided to the executive  causes the
officer  to be  subject to an excise tax  because  the  payment is a  "parachute
payment"  (as  defined in the  Code),  then the  payment  shall be grossed up to
compensate the executive for any excise tax.

     A Change in Control means (a) a change in any two year period in a majority
of the  Incumbent  Directors  of the  Board of the  Company  as  defined  in the
agreement, (b) with certain exceptions, any person becomes the beneficial owner,
directly  or  indirectly,  of 25% or more of the  Company's  outstanding  Common
Stock,  (c)  with  certain  exceptions,   the  consummation  of  the  merger  or
consolidation of the Company with any other corporation, or (d) if a majority of
the members of the Board of Directors in office  immediately prior to a proposed
transaction determine by written resolution that such proposed  transaction,  if
taken,  will be deemed a Change in  Control  and such  proposed  transaction  is
effected.

     The Company also has made provision under its Benefits Restoration Plan and
the SERP for the  crediting  of  additional  years of age and service to certain
executives,  including  those named in the  Summary  Compensation  Table,  whose
employment is terminated  under the  circumstances  described  above following a
change in control of the Company.

     The merger  between  the  company and Oryx  Energy  Company  constituted  a
"change of control" under predecessor  change in control agreements that were in
existence  on the date of the merger.  If,  within  three years of February  26,
1999,  Messers.  Corbett,  McDaniel or Crouch's  employment is terminated by the
Company  for any reason  other than  "cause" as  defined,  or by the officer for
"good  reason," such officer will be entitled to receive a maximum lump sum cash
payment  equal to three times the officer's  annual base salary.  If the payment
made to the  officer  causes the  officer to be subject to an excise tax because
the payment is a "parachute  payment" (as defined in the Code), then the payment
shall be reduced to the extent  necessary so that no portion  thereof is subject
to the  excise  tax,  but only if such  reduction  increases  the net  after-tax
benefit received by the officer. In addition, upon such termination, the officer
will be entitled to receive  amounts that such officer would otherwise have been
entitled to receive under Kerr-McGee's  Supplemental  Executive  Retirement Plan
(SERP) described more fully in the "Retirement Plans."

     In the event of such person's  termination  of employment  within the three
year period for one of the reasons described above, currently the payments under
the agreements in effect on February 26, 1999 will be  approximately  $2,700,000
for Luke R. Corbett,  $1,155,000  for Tom J. McDaniel and $1,200,000 for Kenneth
W. Crouch.  Any such payments  would be credited  against any payments due under
the Continuity Agreements described above.

REPORT ON EXECUTIVE COMPENSATION

     The Executive  Compensation Committee (the "Committee") is comprised of all
of the independent non-employee directors,  William E. Bradford, (Chair), Sylvia
A. Earle, David C. Genever-Watling,  Martin C. Jischke,  William C. Morris, John
J. Murphy,  Leroy C.  Richie,  Matthew R.  Simmons,  Farah M. Walters and Ian L.
White-Thomson,  and is responsible for administering  compensation programs that
make it possible for the Company to attract and retain employees with the skills
and  attitudes  necessary  to provide the Company with a fully  competitive  and
capable management.

     The Committee  reviews the salaries and incentive pay awards as recommended
by the Chief  Executive  Officer (the "CEO") for the officers of the Company and
establishes  the officers'  compensation  and the  compensation  of the CEO. Set
forth below is the report on the Company's executive  compensation  policies for
1999 and how they affected the Company's CEO and the Company's other officers
(including the four other highest paid officers).

     The Company seeks to provide fully competitive levels of total compensation
for its key  executives  through a mix of base salaries,  annual  incentive pay,
long term incentives and other benefits.  The Committee  believes that incentive
or  "at  risk"  compensation  is  a  key  ingredient  in  motivating   executive
performance to maximize  stockholder value and align executive  performance with
company objectives. Total compensation is targeted to be competitive with a peer
group of comparable  energy and chemical  companies,  which  includes  companies
constituting  the  S&P  Domestic   Integrated  Oil  Index  referred  to  in  the
Performance  Graph on page 26, as well as other  comparable  energy and chemical
companies  selected with the assistance of an independent  consulting firm to be
representative  of the Company's size and business  activities (the  "Comparison
Group").  Since the Company has a substantial amount of its business outside the
United  States,   its  compensation   policies  must  also  be   internationally
competitive and flexible. This both attracts and retains high quality management
and facilitates global management.

Base Salaries

     In determining base salaries for officers,  the Committee  annually reviews
current competitive market compensation data of the Comparison Group prepared by
an  independent  consulting  firm.  Base salaries are typically  targeted at the
median of the salary level Comparison  Group.  The Committee's  policy is to set
officers' base salaries at or near the median of base salaries of the Comparison
Group to enable the  Company  to be  competitive  and to attract  and retain key
executives.  When  salary  increases  are made,  the  Committee  also takes into
consideration the individual's  performance based on the CEO's evaluation of the
officer's  performance,  the Committee's evaluation of the CEO's performance and
all officers'  current and prior job related  experience and tenure. No specific
weight is assigned to any individual factor in determining salary increases.

Annual Incentive Compensation

     The Company's Annual Incentive  Compensation  Plan (the "AICP") provides an
opportunity for officers to earn supplemental  incentive  compensation each year
depending on the  performance of the Company's  operating  divisions  versus the
performance  of a peer  Comparison  Group.  Performance  thresholds  established
annually by the Committee must be achieved before payment of AICP awards.

     Under the AICP, an award target is  established  by the Committee  annually
for each executive  officer,  which in 1999 ranged from 35% of base salary up to
75% of base salary.  The executive  officer's  individual target is based on the
officer's level of  responsibility  and Comparison Group competitive data, which
the  Committee  targets  at the 50  percentile  when  determining  an  executive
officer's  award.  An executive  officer may receive up to 200% of the officer's
award  target  if   performance   objectives  are  exceeded  and  the  officer's
performance  excels.  The amount of an  officer's  final award may be reduced or
eliminated by the Committee based on the officer's individual performance.

     During 1999, the Company was successful in accomplishing  several strategic
and growth  goals.  On  February  26,  1999,  Kerr-McGee  completed  the largest
transaction in its history,  merging with Oryx Energy  Company.  The merger more
than  doubled  the  Company's  oil and gas assets and created one of the largest
independent nonintegrated oil and gas exploration and production companies based
in the United States.  The Company was successful in achieving the expected $100
million of annualized synergies from the transaction.

     The Company  continued to expand its worldwide  exploration  and production
activities.  Total  production  increased  nearly  9% to  approximately  295,000
barrels of oil equivalent per day, aided in part by the company-operated  Janice
field in the North Sea that began  production in February  1999,  just 17 months
after  receiving  development  approval  from the U.K.  Department  of Trade and
Industry.  The Company continued to build its exploratory prospect inventory and
at year  end  1999  held  interests  averaging  about  55% in 40  million  gross
undeveloped acres. With about 230 blocks in water depth greater than 1,000 feet,
Kerr-McGee is one of the largest leaseholders among independent  exploration and
production companies in the deep Gulf of Mexico.

     The Company's deepwater exploration activities are also expanding to large,
highly  prospective  blocks in international  basins, in water up to 10,000 feet
deep. Including 1.3 million acres in the Gulf, the Company's worldwide deepwater
inventory  totaled  approximately  17  million  acres  at  year-end  1999,  with
interests  averaging  approximately  50%. In the North Sea, the Company acquired
additional acreage surrounding the core Gryphon area in Quad 9. The Company also
negotiated  and signed a purchase  agreement  to acquire the North Sea assets of
Repsol S. A. that further enhances this core area.  Kerr-McGee closed the Repsol
S. A. transaction in January 2000.

     The  Company  replaced  117% of the 108 million  barrels of oil  equivalent
produced in 1999. Discoveries and field extension in the North Sea and Indonesia
accounted  for much of the 126  million  barrels  of oil  equivalent  in  proven
reserves added in 1999. Finding and development cost, a key performance measure,
was reduced to $4.88 per oil equivalent barrel in 1999. In addition, the Company
has drilled six successful  deepwater wells in the greater  Boomvang/Nansen area
and has announced an encouraging discovery in Bohai Bay, China.

     The Company  continued to expand its world-class  titanium  dioxide pigment
operations  with  completion  of a  25%  expansion  of  its  flagship  Hamilton,
Mississippi  facility to 188,000 tonnes of annual domestic production  capacity.
The Company accomplished the expansion on schedule and within budget.

     The  Company   implemented  a  cost  reduction  program  at  the  Hamilton,
Mississippi  plant and achieved its goal of realizing cost savings totaling $100
per tonne by year end.  The Company  won market  acceptance  of a new  universal
grade of pigment and is currently trial testing an additional pigment grade. The
impact of these  activities  resulted  in  record  operating  profit,  excluding
special items, of $128 million for the chemical division, up 11% from 1998.

     The Company  reported 1999 net income before  special items of $296 million
and cash flow from  operating  activities  of $713 million.  Kerr-McGee's  total
return to shareholders was 68.7% in 1999, the highest among its peers in the oil
industry.

Long Term Incentives

     With the  consent  of its  stockholders,  the  Company  has for many  years
approved the use of Company  stock in the form of stock  options and  restricted
stock awards to provide long-term  incentive  compensation for the Company's key
executives.  The Committee believes that stock compensation establishes a direct
relationship  between the  compensation  of  executives  and the interest of the
stockholders and is an important retention tool for attracting and retaining key
employees by rewarding  management's  performance based on objectively  measured
results.

     Stock  ownership   guidelines  have  been  established  for  the  Company's
officers.  The stock  ownership  goals  are based on the value of the  Company's
stock  and are  expressed  in a  multiple  of the  officer's  base  salary.  The
Committee  believes that stock ownership by the Company's  officers is important
and promotes  commitment to the long-term  success of Kerr-McGee.  The Committee
periodically reviews the guidelines and the officers' stock ownership.

     The aggregate value of stock options granted to each officer, including the
CEO, is based on a percentage of the individual's  salary. The percentage is set
annually  by  the  Committee  after  considering   surveys  and  reports  by  an
independent  consulting firm as to competitive awards made within the Comparison
Group,  as well as the  individual's  level of  responsibility  and a subjective
performance  evaluation.  In determining  the number of options to be granted an
officer,  the  Committee  targets the 50th  percentile of  competitive  data. In
making the 1999 awards,  the Committee  also  considered the amount and terms of
prior awards. The number of stock options granted in 1999 to Mr. Corbett and the
four other highest paid officers is set forth in the Option Grants Table.

     The Company's Long Term Incentive Plan was approved by stockholders in 1998
and the  Committee  expects  that all income  that may be  received  through the
exercising  of  stock  options  granted  in 1999 to  officers  will  qualify  as
performance-based compensation as defined
under Section 162(m) of the Code.

Compensation of the Chief Executive Officer

     The Chief Executive Officer's compensation is determined in accordance with
the policies  described above. In establishing  Mr.  Corbett's base salary,  the
Committee  considers  competitive  salaries  of CEOs for  comparable  energy and
chemical  companies  within the  Comparison  Group as compiled by an independent
consulting  firm.  Mr.  Corbett's  annual  base salary was  increased  effective
February 1999 to $725,000.

     Mr. Corbett's  incentive  compensation for 2000 will be determined  through
the AICP in May 2000.  Additionally,  the Committee will take into consideration
several substantial accomplishments in 1999, with no specific weight assigned to
any  individual  accomplishment.  Consideration  will be given to Mr.  Corbett's
significant role in negotiating and completing the Kerr-McGee/Oryx merger, which
was the largest  transaction in the Company's history,  increasing the Company's
worldwide exploration inventory, negotiating and signing a purchase agreement to
acquire the North Sea assets of Repsol S.A.,  the excellent  performance  of the
Company's  world-class  titanium dioxide pigment operations,  and increasing the
total return to stockholders.

     Under Mr.  Corbett's  leadership,  the Company  reported net income  before
special  items of $296  million,  cash flow from  operating  activities  of $713
million and a total  return to  shareholders  of 68.7%.  Kerr-McGee's  return on
average equity (excluding merger-related costs) was 19 % in 1999 compared with a
negative return in 1998. Mr. Corbett's role in these significant accomplishments
will be considered for incentive compensation by the Committee in May 2000.

     The Committee  believes that executive  compensation for 1999 appropriately
reflects its policy to align such compensation  with overall business  strategy,
values and  management  initiatives  and to ensure that the Company's  goals and
performance are consistent with the interests of its stockholders.

Federal Income Tax Deductibility

     Code  Section   162(m)   generally   limits  the  corporate   deduction  on
compensation  paid to the Chief Executive Officer and the next four highest paid
officers to $1 million  during any fiscal year  unless such  compensation  meets
certain  performance-based  requirements.  At the  stockholders'  meeting in May
1998,  the  Company's  Annual  Incentive   Compensation  Plan  was  approved  by
stockholders so that  "performance-based"  compensation  generated  through this
plan would be considered exempt from the deduction limit.

     The Stock to be  distributed  under the Plan may be either  authorized  and
unissued shares or issued shares of the Company,  but grants of Restricted Stock
shall be made in  treasury  shares.  The  maximum  amount of Stock  which may be
issued under the Plan in  satisfaction of exercised  Options or SARs,  issued as
Restricted  Stock or  issued  under  the Long Term  Performance  Plan  shall not
exceed, in the aggregate,  two million five hundred thousand  (2,500,000) shares
of which no more may be granted, as follows:

     (a) Restricted Stock to Employees                        450,000 shares

     (b) Stock Options and Restricted Stock to                300,000 shares
         Non-Employee Directors, but no more
         than 100,000 shares to Restricted Stock

     Stock  subject to an Option which for any reason is cancelled or terminated
without  having been  exercised,  or Stock awarded as Restricted  Stock which is
forfeited,  shall again be available for grants and Awards under the Plan. Stock
not issued because the holder of any Option exercises the accompanying SAR shall
not again be subject to award by the Committee.

                                   Article VI

                                 Stock Options
                                 -------------

(a)  Grant of Options.

     (i) The Committee may, at any time and from time to time prior to April 30,
2010,  grant  Options  under  the Plan to  eligible  Employees  or  Non-Employee
Directors,  for such  numbers of shares and having  such terms as the  Committee
shall designate,  subject however,  to the provisions of the Plan. The Committee
will also determine the type of Option granted (e.g.  ISO,  nonstatutory,  other
statutory  Options  as from  time to time  may be  permitted  by the  Code) or a
combination of various types of Options. Options designated as ISOs shall comply
with all the provisions of Section 422 of the Code and  applicable  regulations.
The aggregate  Fair Market Value  (determined at the time the Option is granted)
of Stock with  respect to which  ISOs are  exercisable  for the first time by an
individual during a calendar year under all plans of the Company, any Subsidiary
and any LLC  shall not  exceed  $100,000.  The date on which an Option  shall be
granted shall be the date of the Committee's  authorization  of such grant.  Any
individual  at any one time and from time to time may hold more than one  Option
granted under the Plan or under any other Stock plan of the Company.

     (ii) Each Option shall be  evidenced  by a Stock  Option  Agreement in such
form and containing such  provisions  consistent with the provisions of the Plan
as the Committee from time to time shall approve.

(b) Exercise Price. The price at which shares of Stock may be purchased under an
Option  shall not be less than 100% of the Fair Market Value of the Stock on the
date the Option is granted.

(c) Option Period.  The period during which an Option may be exercised  shall be
determined by the Committee;  provided, that such period will not be longer than
ten years from the date on which the Option is granted in the case of ISOs,  and
ten years and one day in the case of other  Options.  The date or dates on which
installment  portion(s)  of an Option  may be  exercised  during  the term of an
Option shall be  determined by the Committee and may vary from Option to Option.
The Committee may also  determine to  accelerate  the time at which  installment
portion(s) of an outstanding Option may be exercised.

(d)  Termination of Employment.  An Option shall  terminate and may no longer be
exercised  three  months  after the  Optionee  ceases to be an Employee  for any
reason  other than  Total  Disability,  death or  Retirement.  If an  Optionee's
employment is terminated by reason of Total Disability or Retirement the vesting
provision will lapse and such Option may be exercised within the period,  not to
exceed four years following such termination,  specified by the Committee in the
instrument  evidencing  the Option.  If the Optionee dies while in the employ of
the Company,  a Subsidiary or LLC, or within three months after the  termination
of such  employment,  the  vesting  provisions  will lapse and such  Option may,
within  the  lesser of one year  after the  Optionee's  death or the term of the
option, be exercised by the legal representative of the Optionee's estate, or if
it has been distributed as part of the estate,  by the person or persons to whom
the  Optionee's  rights under the Option shall pass by will or by the applicable
laws of descent and distribution.  In no event may an Option be exercised to any
extent by anyone after the expiration or termination of the Option.

(e) Payment for Shares.

     (i) The exercise price of an Option shall be paid to the Company in full at
the time of exercise at the election of the Optionee (1) in cash,  (2) in shares
of Stock having a Fair Market Value equal to the aggregate exercise price of the
Option  and  satisfying  such  other  requirements  as  may  be  imposed  by the
Committee, (3) in shares of Restricted Stock having a Fair Market Value equal to
the  aggregate   exercise  price  of  the  Option  and  satisfying   such  other
requirements  as may be imposed by the Committee,  (4) partly in cash and partly
in such shares of Stock or Restricted  Stock, (5) to the extent permitted by the
Committee,  through the withholding of shares of Stock (which would otherwise be
delivered to the Optionee)  with an aggregate  Fair Market Value on the exercise
date equal to the  aggregate  exercise  price of the Option or (6)  through  the
delivery  of  irrevocable  instructions  to a broker to deliver  promptly to the
Company an amount  equal to the  aggregate  exercise  price of the  Option.  The
Committee  may limit the extent to which shares of Stock or shares of Restricted
Stock may be used in exercising  Options.  No Optionee  shall have any rights to
dividends  or other  rights of a  stockholder  with  respect  to shares of Stock
subject to an Option until the Optionee has given written  notice of exercise of
the  Option,  paid in full for such  shares of Stock  and,  if  applicable,  has
satisfied any other conditions imposed by the Committee pursuant to the Plan.

    (ii) If shares of Restricted  Stock are used to pay the exercise price of an
Option,  an equal  number of  shares of Stock  delivered  to the  Optionee  upon
exercise  of an  Option,  shall  be  subject  to the same  restrictions  for the
remainder of the Restriction Period.

(f) Annual  Maximum  Performance.  Options  granted to any one  Optionee may not
exceed one hundred fifty thousand (150,000) shares of stock per calendar year.

                                  Article VII

                           Stock Appreciation Rights
                           -------------------------

(a) Grant. The Committee may affix SARs to an Option,  either at the time of its
initial  granting to the Optionee or at a later date.  The addition of such SARs
must be  accomplished  prior to the  completion  of the period  during which the
Option may be exercised and such exercise period may not be extended beyond that
which was  initially  established.  The  Committee  may  establish SAR terms and
conditions at the time such SAR is established.

(b)  Exercise.

     (i) A SAR shall be  exercisable  at such time as may be  determined  by the
Committee  and a SAR shall be  exercisable  only to the extent  that the related
Option  could be  exercised.  Upon the  exercise of a SAR,  that  portion of the
Option underlying the SAR will be considered as having been  surrendered.  A SAR
shall be  automatically  exercised at the end of the last  business day prior to
the stated  expiration date of the unexercised  portion of the related Option if
on such date the Fair Market Value of Stock  exceeds the Option  exercise  price
per share.

     (ii)The  Committee may impose any other  conditions  upon the exercise of a
SAR,  consistent  with the  Plan,  which it deems  appropriate.  Such  rules and
regulations  may govern the right to exercise SARs granted prior to the adoption
or amendment of such rules and regulations as well as SARs granted thereafter.

     (iii) Upon the exercise of a SAR, the Company  shall give to an Optionee an
amount (less any applicable  withholding  taxes) equivalent to the excess of the
Fair Market Value of the shares of Stock for which the right is exercised on the
date of such exercise  over the exercise  price of such shares under the related
Option. Such amount shall be paid to the Optionee either in cash or in shares of
Stock or both as the Committee shall determine.  Such  determination may be made
at the  time  of the  granting  of the  SAR  and  may  be  changed  at any  time
thereafter.  No  fractional  shares of Stock  shall be issued and the  Committee
shall determine  whether cash shall be given in lieu of such fractional share or
whether such fractional share shall be eliminated.

(c) Expiration or Termination.

     (i) Subject to (c)(ii), each SAR and all rights and obligations  thereunder
shall expire on a date to be determined by the Committee.

     (ii)A SAR shall terminate and may no longer be exercised upon the exercise,
termination or expiration of the related Option.

                                  Article VIII

                             Restricted Stock Plan
                             ---------------------

(a) At the time of making a grant of  Restricted  Stock or making  payment of an
Award in Restricted Stock to an Employee or Non-Employee Director, the Committee
shall establish a Restriction Period and assign such terms, conditions and other
restrictions  to the Restricted  Stock as it shall  determine  applicable to the
Restricted Stock to be issued in settlement of such grant or Award.

(b) Restricted  Stock will be represented by a Stock  certificate  registered in
the name of the Restricted Stock recipient.  Such certificate,  accompanied by a
separate duly endorsed  stock power,  shall be deposited  with the Company.  The
recipient shall be entitled to receive  dividends during the Restriction  Period
and  shall  have  the  right  to  vote  such  Restricted  Stock  and  all  other
stockholder's  rights,  with the exception  that (i) the  recipient  will not be
entitled to delivery of the Stock  certificate  during the  Restriction  Period,
(ii) the  Company  will  retain  custody  of the  Restricted  Stock  during  the
Restriction Period and (iii) a breach of the terms and conditions established by
the Committee  pursuant to the Award will cause a forfeiture  of the  Restricted
Stock.  Subject to Article  VI,  Section  (e),  Restricted  Stock may be used to
exercise  Options.   The  Committee  may,  in  addition,   prescribe  additional
restrictions, terms and conditions upon or to the Restricted Stock.

     (i)  Termination  of  Employment.  The Committee  may establish  such rules
concerning  the  termination  of employment  of a recipient of Restricted  Stock
prior to the  expiration  of the  applicable  Restriction  Period as it may deem
appropriate from time to time.

     (ii)Restricted  Stock Agreement.  Each grant of, or payment of an Award in,
Restricted Stock shall be evidenced by a Restricted Stock Agreement in such form
and containing such terms and conditions not inconsistent with the provisions of
the Plan as the Committee from time to time shall approve.

(c) The  Committee  shall not grant  Restricted  Stock in excess of four hundred
fifty thousand (450,000) shares of Stock during the term of this Agreement.

                                   Article IX

                                Performance Plan
                                ----------------

(a)  Administrative  Procedure.  The  Committee  shall  designate  Employees  as
Performance Participants to become eligible to receive Awards under the plan and
shall establish Performance Periods under the Performance Plan.

(b)  Indicators of  Performance.  The Committee  shall  establish  Indicators of
Performance applicable to the Performance Period.  Indicators of Performance are
utilized  to  determine  amount  and  timing  of  Awards,  and may vary  between
Performance  Periods.  Indicators of Performance  may include,  but shall not be
limited to, various  financial and operating  measures,  and may be based on the
Company's performance compared to one or more selected companies during the same
Performance Period or may be related solely to the Company's  performance during
the Performance  Period, or a combination of such indicators.  The Committee may
take into consideration,  and make appropriate adjustments for, events occurring
during the  Performance  Period which the Committee  concludes have affected the
performance  of the Company or any  selected  company with respect to any of the
Indicators of Performance.

(c) Award  Adjustment.  Subject to the terms of the Plan, the Committee may make
adjustments in Awards to Performance Plan Participants.

(d) Performance Awards.  Awards may be in the form of performance shares,  which
are units valued by reference to shares of stock or performance units, which are
units valued by reference to financial measures or property other than stock and
shall be subject  to such terms and  conditions  and other  restrictions  as the
Committee  shall assign.  At the time of making grants of Awards,  the Committee
shall  establish such terms and conditions as it shall  determine  applicable to
such Awards.  Awards may be paid out in cash,  Stock,  Restricted  Stock,  other
property  or  combination  thereof.  Recipients  of Awards are not  required  to
provide consideration other than the rendering of service.

(e) Partial Performance Period Participation.  The Committee shall determine the
extent to which an Employee shall  participate in a partial  Performance  Period
because of becoming  eligible to be a  Performance  Plan  Participant  after the
beginning of such Performance Period.

                                   Article X

                        Adjustment Upon Changes In Stock
                        --------------------------------

     The number of shares of Stock  which may be issued  pursuant  to this Plan,
the number of shares covered by each  outstanding  Option,  the Option  exercise
price per share,  the  number of shares  granted as  Restricted  Stock,  and the
number of shares  representing a Performance Plan Participant's  Award under the
Performance Plan, shall be adjusted  proportionately,  and any other appropriate
adjustments  shall be made,  for any increase or decrease in the total number of
issued and  outstanding  Stock (or change in kind)  resulting from any change in
the  Stock  or  Options   through  a  merger,   consolidation,   reorganization,
recapitalization,  subdivision  or  consolidation  of  shares  or other  capital
adjustment or the payment of a Stock  Dividend or other increase or decrease (or
change in kind) in such shares. In the event of any such adjustment,  fractional
shares shall be  eliminated.  Appropriate  adjustment  shall also be made by the
Committee in the terms of SARs to reflect the foregoing changes.

                                   Article XI

                               Change In Control
                               -----------------

Notwithstanding  anything to the contrary in the Plan,  in the event of a Change
in Control:

(i) If during a Restriction  Period(s)  applicable  to  Restricted  Stock issued
under the Plan, all  restrictions  imposed  hereunder on such  Restricted  Stock
shall lapse effective the date of the Change in Control;

(ii) If during a Performance  Period(s) applicable to an Award granted under the
Plan, a Participant shall earn no less than the number of performance  shares or
performance  units which the  participant  would have earned if the  Performance
Period(s) had terminated as of the date of the Change in Control; or

(iii) Any  outstanding  Options or SARs that are not  exercisable  shall  become
exercisable  effective as of the date of a Change in Control.  If an  Optionee's
employment is terminated  within 24 months of the effective  date of a Change in
Control,  to the  extent  that any  Option  was  exercisable  at the time of the
Optionee's  termination of employment,  such Option may be exercised within four
years following the date of termination of employment.

     For  purposes of the Plan,  a "Change in  Control"  shall be deemed to have
occurred if:

(a) Any  person  ("Person")  as defined  in  Section  3(a)(9) of the  Securities
Exchange Act of 1934, as amended (the  "Exchange  Act"),  and as used in Section
13(d) and 14(d) thereof,  including a "group" as defined in Section 13(d) of the
Exchange  Act, but  excluding  the Company and any  subsidiary  and any employee
benefit plan sponsored or maintained by the Company or any subsidiary (including
any trustee of such plan acting as trustee), directly or indirectly, becomes the
"beneficial  owner" (as  defined  in Rule  13d-3  under the  Exchange  Act),  of
securities of the Company  representing 25% or more of the combined voting power
of the Company's then outstanding  securities (other than indirectly as a result
of the Company's redemption of its securities); or

(b) The consummation of any merger or other business combination of the Company,
sale of 50% or more of the Company's  assets,  liquidation or dissolution of the
Company or  combination  of the foregoing  transactions  (the  "Transaction(s)")
other than a Transaction  immediately  following  which the  shareholder  of the
Company  and any  trustee or  fiduciary  of any Company  employee  benefit  plan
immediately  prior to the  Transaction  own at least  60% of the  voting  power,
directly or indirectly,  of (A) the surviving  corporation in any such merger or
other  business  combination;  (B) the  purchaser or successor to the  Company's
assets; (C) both the surviving corporation and the purchaser in the event of any
combination  of  Transactions;  or (D) the parent  company  owning  100% of such
surviving  corporation,  purchaser  or both the  surviving  corporation  and the
purchaser, as the case may be; or

(c)  Within  any  twenty-four  month  period,  the  persons  who were  directors
immediately  before the  beginning  of such period (the  "Incumbent  Directors")
shall cease (for any reason other than death) to  constitute at least a majority
of the Board or the board of directors  of a successor to the Company.  For this
purpose,  any  director  who was not a director at the  beginning of such period
shall be deemed to be an Incumbent  Director if such director was elected to the
Board  by,  or on the  recommendation  of or with  the  approval  of,  at  least
two-thirds of the directors who then  qualified as Incumbent  Directors (so long
as such  director was not  nominated by a person who  commenced or threatened to
commence an election  contest or proxy  solicitation by or on behalf of a Person
(other than the Board) or who has entered  into an  agreement to effect a Change
in Control or expressed an intention to cause such a Change in Control); or

(d) A majority of the members of the Board of  Directors  in office  immediately
prior to a proposed  Transaction  determine  by a written  resolution  that such
proposed  Transaction,  if taken,  will be deemed a Change in  Control  and such
proposed Transaction is consummated.

                                  Article XII

                                 Miscellaneous
                                 -------------

(a) Except as otherwise required by law, no action taken under the Plan shall be
taken into account in determining  any benefits  under any pension,  retirement,
thrift, profit sharing,  group insurance or other benefit plan maintained by the
Company or any Subsidiaries,  unless such other plan  specifically  provides for
such inclusion.

(b)  Employees  may elect to defer the gain from any award under this Plan under
the  terms and  conditions  of the  Kerr-McGee  Corporation  Executive  Deferred
Compensation Plan.

(c) Except as  provided in Section  (d) of this  Article  XII, no Option or SAR,
grant of Restricted  Stock or Award under this Plan shall be transferable  other
than by will or the laws of descent and distribution. Any Option or SAR shall be
exercisable (i) during the lifetime of an Optionee,  only by the Optionee or, to
the  extent   permitted  by  the  Code,  by  an  appointed   guardian  or  legal
representative  of the Optionee,  and (ii) after death of the Optionee,  only by
the Optionee's legal  representative  or by the person who acquired the right to
exercise such Option or SAR by bequest or  inheritance or by reason of the death
of the Optionee.

(d) The  Committee  may, in its  discretion,  authorize  all or a portion of the
Options to be granted to an  Optionee to be on terms  which  permit  transfer by
such  Optionee to an  immediate  family  member of the Optionee who acquires the
options  from the Optionee  through a gift or a domestic  relations  order.  For
purposes of this Section (d),  "family  member"  includes any child,  stepchild,
grandchild,  parent, stepparent,  grandparent,  spouse, sibling,  mother-in-law,
father-in-law,  son-in-law,  daughter-in-law,  brother-in-law  or sister-in-law,
including  adoptive  relationships,  trusts for the  exclusive  benefit of these
persons and any other entity owned solely by these  persons,  provided  that the
Stock  Option  Agreement  pursuant to which such  Options  are  granted  must be
approved by the Committee and must expressly  provide for  transferability  in a
manner  consistent  with this  Section  and  provided  further  that  subsequent
transfers of transferred  options shall be prohibited except those in accordance
with Section (c) of this Article XII. Following transfer, any such options shall
continue  to be  subject  to the same terms and  conditions  as were  applicable
immediately  prior to  transfer.  The events of  termination  of  employment  of
Section (d) of Article VI hereof  shall  continue to be applied  with respect to
the original  Optionee,  following which the options shall be exercisable by the
Transferee  only to the extent and for the periods  specified  in Section (d) of
Article VI.

(e) The Company shall have the right to withhold from any  settlement  hereunder
any federal,  state,  or local taxes required by law to be withheld,  or require
payment in the amount of such  withholding.  If  settlement  hereunder is in the
form of Stock, such withholding may be satisfied by the withholding of shares of
Stock by the  Company,  unless the  Optionee  shall pay to the Company an amount
sufficient  to cover  the  amount of taxes  required  to be  withheld,  and such
withholding of shares does not violate any applicable laws, rules or regulations
of federal, state or local authorities.

(f)  Transfer  of  employment  between  the  Company,  a  Subsidiary  or Limited
Liability Company, or between Limited Liability Companies and Subsidiaries shall
not constitute  termination  of employment for the purpose of the Plan.  Whether
any leave of absence shall constitute termination of employment for the purposes
of the Plan shall be determined in each case by the Committee.

(g) All administrative  expenses  associated with the administration of the Plan
shall be borne by the Company.

(h) The titles and headings of the articles in this Plan are for  convenience of
reference  only and in the event of any conflict,  the text of the Plan,  rather
than such titles or headings, shall control.

(i) No grant or Award to an employee  under the Plan or any  provisions  thereof
shall  constitute any agreement for or guarantee of continued  employment by the
Company and no grant or Award to a Non-Employee  Director  shall  constitute any
agreement for or guarantee of continuing as a Non-Employee Director.

(j) The  Committee  shall have such  duties and  powers as may be  necessary  to
discharge its responsibilities  under this Plan, including,  but not limited to,
the ability to construe and interpret the Plan and resolve any ambiguities  with
respect to any of the terms and  provisions  hereof as written and as applied to
the operation of the Plan.

                                  Article XIII

                           Amendment And Termination
                           -------------------------

     The Board may at any time  terminate  or amend this Plan in such respect as
it shall deem advisable,  provided,  the Board may not, without further approval
of the  stockholders  of the  Company,  amend the Plan so as to (i) increase the
number of shares of Stock which may be issued under the Plan, except as provided
for in Article X, or change Plan  provisions  relating to  establishment  of the
exercise  prices  under  Options  granted,  (ii) extend the duration of the Plan
beyond the date  approved  by the  stockholders  or (iii)  increase  the maximum
dollar  amount of ISOs which an  individual  Optionee  may  exercise  during any
calendar  year  beyond  that  permitted  in the Code and  applicable  rules  and
regulations of the U.S. Treasury Department.  No amendment or termination of the
Plan shall,  without the consent of the Optionee or Plan  participant,  alter or
impair  any of the  rights or  obligations  under any  Options  or other  rights
theretofore granted such person under the Plan.

                                  Article XIV

                              Duration Of The Plan
                              --------------------

     The  effective  date of this  Plan  shall  be May 1,  2000.  If not  sooner
terminated  by the  Board,  this Plan shall  terminate  on April 30,  2010,  but
Options and other  rights  theretofore  granted and any  Restriction  Period may
extend beyond that date and the terms of the Plan shall continue to apply.



                                 March 27, 2000




To:      Participants In The Kerr-McGee Corporation
         SAVINGS INVESTMENT PLAN and/or the
         EMPLOYEE STOCK OWNERSHIP PLAN Dated September 12, 1989:

As a participant in the Kerr-McGee  Corporation  Savings Investment Plan ("SIP")
and/or the Kerr-McGee  Corporation Employee Stock Ownership Plan dated September
12, 1989 ("ESOP"),  you owned shares of Common Stock of the Company on March 10,
2000,  the  record  date  for  stockholders  entitled  to  vote  at  the  annual
stockholders'  meeting to be held on May 9, 2000. This stock is held in trust by
Putnam Fiduciary Trust Company, as Trustee for the SIP and State Street Bank and
Trust Company, as Trustee for the ESOP.

Each plan  provides  that the shares of Common  Stock of the Company  which have
been allocated to your account will be voted by the Trustees in accordance  with
your  instructions.  Both the SIP and ESOP  provide  that  shares  allocated  to
participants for which no Voting Instructions are received shall be voted by the
Trustees in the same proportion as those allocated shares for which instructions
are  received.  The ESOP  also  provides  that  shares  which  have not yet been
allocated  (approximately 700,000 shares) shall also be voted by the Trustees in
the same  proportion  as those  allocated  shares  for  which  instructions  are
received.

Your vote is important  and you are urged to vote  promptly!  If the Trustees do
not receive Voting  Instructions from you, the shares in both plans for which no
instructions  are received and the unallocated  shares in the ESOP will be voted
in the same proportion as the total shares for which  instructions  are received
by the Trustees.

Enclosed for your information and use are the following:

1.       Notice of the Annual  Meeting and Proxy  Statement.  (Since your shares
         will be voted through the Trustees,  the enclosed  Voting  Instructions
         replace the Proxy referred to in the Proxy Statement.)

2.       Voting  Instructions  to  the  Trustee  for  each  plan for your use in
         directing the Trustees to vote your shares.

3.       A postage-paid,  self-addressed envelope for your use in returning your
         Voting  Instructions  to UMB BANK N.A.  which will  tabulate the Voting
