                         REPORT OF INDEPENDENT AUDITORS


Kerr-McGee Corporation Benefits Committee
Kerr-McGee Corporation Savings Investment Plan


     We have  audited the  accompanying  statement of net assets  available  for
benefits of  Kerr-McGee  Corporation  Savings  Investment  Plan (the Plan) as of
December 31, 2002 and 2001,  and the related  statement of changes in net assets
available  for benefits for the year ended  December 31, 2002.  These  financial
statements are the responsibility of the Plan's  management.  Our responsibility
is to express an opinion on these financial statements based on our audits.

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

     In our opinion,  the financial statements referred to above present fairly,
in all material  respects,  the net assets available for benefits of the Plan at
December  31,  2002 and 2001,  and the changes in its net assets  available  for
benefits for the year ended  December 31, 2002,  in conformity  with  accounting
principles generally accepted in the United States.

     Our  audits  were  performed  for the  purpose of forming an opinion on the
financial statements taken as a whole. The accompanying  supplemental  schedules
of  assets  (held  at end of year)  as of  December  31,  2002,  and  reportable
transactions  for the  year  then  ended,  are  presented  for the  purposes  of
additional analysis and are not a required part of the financial  statements but
are  supplementary  information  required by the Department of Labor's Rules and
Regulations for Reporting and Disclosure  under the Employee  Retirement  Income
Security Act of 1974. The supplemental  schedules are the  responsibility of the
Plan's  management.  The  supplemental  schedules  have  been  subjected  to the
auditing procedures applied in our audit of the financial statements and, in our
opinion, are fairly stated in all material respects in relation to the financial
statements taken as a whole.

                 KERR-McGEE CORPORATION SAVINGS INVESTMENT PLAN


                          NOTES TO FINANCIAL STATEMENTS

                           DECEMBER 31, 2002 AND 2001


(1)  DESCRIPTION OF THE PLAN

     General -

     The Kerr-McGee  Corporation Savings Investment Plan (the Plan) is a defined
     contribution plan in which eligible employees of Kerr-McGee Corporation and
     its  affiliated  companies  (collectively  referred to as the  Company) may
     participate.

     In  August  2001,  the  Company  completed  the  acquisition  of all of the
     outstanding  shares of common stock of HS Resources,  Inc. (HSR).  Prior to
     the  acquisition,  HSR had a defined  contribution  plan, the HS Resources,
     Inc.  401(k) & Profit  Sharing Plan (HSR plan).  The assets of the HSR plan
     were transferred into the Plan during October 2002. The amount  transferred
     is shown as Transfer  from prior trustee on the Statement of Changes in Net
     Assets Available for Benefits.

     The  Plan  allows   participants   to  defer   taxable   earnings   through
     contributions  to the Plan as  provided  for  under  Section  401(k) of the
     Internal  Revenue Code (the Code), and to borrow from their accounts within
     the Plan.

     The Plan is administered by the Kerr-McGee  Corporation  Benefits Committee
     (the  Committee),  which is  appointed  by the  Board of  Directors  of the
     Company.  Accounting  and  administration  for the Plan are provided by the
     Company at no cost to the Plan. In addition,  all expenses of the Trust are
     borne  by  the  Company.   During   2002,   the  Company  paid  $13,000  of
     administrative and trust expenses on behalf of the Plan.

     The Company  intends to continue  the Plan  indefinitely,  but reserves the
     right to alter,  amend,  modify,  revoke or terminate  the Plan at any time
     upon the  direction of the  Company's  Board of  Directors.  If the Plan is
     terminated for any reason, the Committee will direct that the participants'
     account  balances be distributed  as soon as practical.  The Company has no
     continuing  liability  under the Plan  after the final  disposition  of the
     assets of the Plan.

     Effective January 1, 1990, all employer matching  contributions are made to
     the Kerr-McGee  Corporation Employee Stock Ownership Plan (ESOP), which was
     established in September 1989. All matching  contributions  are invested in
     Kerr-McGee  Corporation  common  stock.  The ESOP is not part of the  Plan;
     therefore,  the employer  contributions to the ESOP and the ESOP assets and
     earnings are not included in the  accompanying  Plan financial  statements.
     The maximum Company matching  contribution is 6% of compensation as defined
     in the Plan, and the maximum  employee  contribution is 15% of compensation
     as defined in the Plan. The Company's  matching  contributions  to the ESOP
     during 2002  totaled  $12,935,000.  Common stock of the Company held by the
     ESOP and allocated to participant's  accounts totaled 1,425,281 shares with
     a market value of $63,076,000  at December 31, 2002.  Employees are allowed
     to participate in the Plan from their initial date of employment.

     Effective  January 1,  2000,  all  participants  in the ESOP have an annual
     option to diversify up to 25% of their year-end Kerr-McGee stock balance in
     the ESOP into investment options available in the Plan. This option must be
     exercised by March 31 of each year. The amount  diversified  during 2002 is
     shown as  Transfer  from ESOP on the  Statement  of  Changes  in Net Assets
     Available for Benefits.

     Prior to January 1, 1990,  employer matching  contributions  were made into
     the Plan and invested in  Kerr-McGee  Corporation  common  stock.  The 2002
     activity related to these nonparticipant-directed contributions is shown in
     Note 4.

     The participants'  contributions to the Plan and earnings thereon are fully
     vested at all  times.  Each  participant's  account  is  credited  with the
     participant's  contributions  and an allocation of Plan earnings.  With the
     exception of the  nonparticipant-directed  portion of the Kerr-McGee  Stock
     Fund,  participants designate how their balances are invested in any one or
     more of several investment options.

     On termination of service, including terminations due to death, disability,
     or retirement,  a participant  or  participant's  beneficiary  may elect to
     receive  an amount  equal to the value of the  participant's  account.  The
     normal form of such  distribution  is a single lump sum  payment;  however,
     certain  eligible  members may elect to have an annuity  purchased  from an
     insurance company in lieu of a lump sum payment.  Terminating  participants
     with more than $5,000 in the Plan may defer  distribution until age 70 1/2.
     Investments  relating to these  participants  remain in the Trust until the
     terminated  participant  requests  distribution.   Participants  who  defer
     distribution continue to share in earnings and losses of the Plan.

     The following is a description of the investment  options  available  under
     the Plan at December 31, 2002:

          Kerr-McGee Stock Fund - common stock of the Company.

          Fidelity  Growth  Company  Fund - invest in common  stock of companies
          believed to have above-average growth potential.

          Fidelity  Balanced Fund - normally invests 60% of its assets in stocks
          and 40% of its assets in bonds.

          Fidelity Diversified International Fund - invests primarily in foreign
          securities.

          Fidelity  Dividend  Growth  Fund -  invests  at least 80% of its total
          assets  in  companies  believed  to have the  potential  for  dividend
          growth.

          Fidelity  Mid-Cap  Stock  Fund - invests at least 80% of its assets in
          common stocks of companies with medium market capitalizations.

          Managed Income  Portfolio II - invests in investment  contracts issued
          by insurance companies and other financial institutions.

          Spartan U.S. Equity Index Fund - invests at least 80% of its assets in
          common stocks included in the S&P 500.

          Pimco Total Return Fund - invests in all types of bonds.

          Baron  Growth Fund - invests  primarily in  small-cap  companies  with
          market values between $100 million and $1.5 billion.

          Oakmark  Select  Fund - invests  primarily  in  common  stocks of U.S.
          companies.

          Liberty  Small-Cap  Fund - invests  primarily in common stock of small
          companies believed to be undervalued.

          Aim Basic  Value Fund - invests  65% of assets in  securities  of U.S.
          issuers  with market  capitalization  of greater than $500 million and
          35% of assets in U.S. issuers with market  capitalization of less than
          $500 million.

          Royce  Low-Priced  Stock Fund - invests in both  small- and  micro-cap
          companies that are trading for less than $20 per share.


     SMART and CAPITAL Savings Programs -

     All  participants  participate  in the Plan  under the  SMART  and  CAPITAL
     Savings Programs. Participants may direct their savings, up to a maximum of
     15% of  compensation,  to be invested in 1% increments among one or more of
     the funds provided for under the Plan. An unlimited number of transfers are
     allowed between funds.

     Contributions  to the  SMART  Savings  Program  are  from  a  participant's
     compensation,  before income taxes. The  participant's  income taxes on the
     pre-tax  contributions are deferred until the contributions are distributed
     after  termination,  at the time of hardship  withdrawal,  or under minimum
     distribution  rules  at  age 70  1/2.  The  annual  SMART  Savings  Program
     contribution  limitation is subject to annual adjustments for inflation and
     was $11,000 for 2002 in  accordance  with the  Internal  Revenue  Code (the
     Code). Participant contributions in excess of this amount are considered to
     be contributions to the CAPITAL Savings Program.

     Contributions  to the  CAPITAL  Savings  Program  are from a  participant's
     compensation, after income taxes. If a participant has authorized less than
     15% of their  compensation to be contributed to the SMART Savings  Program,
     they  may  contribute  the  remaining  whole  percentages  up to 15% to the
     CAPITAL Savings Program.  Participant  contributions may be invested in the
     same proportions and the same funds as outlined above for the SMART Savings
     Program. The maximum  contributions  allowed to each program may be limited
     for  highly   compensated   employees,   depending   upon  the  balance  of
     contributions at all levels.

     Participants  may borrow from the Plan against their  contributions  to the
     SMART and CAPITAL  Savings  Programs and against their  interest in Company
     matching  contributions  held in the Plan. New loans to  participants  bear
     interest at a fixed rate equal to the prime rate (as  published in The Wall
     Street Journal),  plus 1.0%. Such interest is credited to the participant's
     accounts in the Plan when repaid.  The average interest rate for new loans,
     which is adjusted  quarterly,  was 5.81% for 2002. The minimum loan amount,
     determined  periodically by the Committee, is currently $1,000. The maximum
     amount of all loans to a participant  under the Plan and any other plans of
     any employer may not exceed the lesser of (a) $50,000, reduced by an amount
     equal to the difference between (i) the participant's  highest loan balance
     under the Plan during the one-year period ending on the day before the date
     on which  such loan is made and (ii) the  outstanding  loan  balance of the
     participant  under the Plan on the date on which  such loan was made or (b)
     one-half the current value of the participant's interest in their accounts.
     Loans must be repaid  within five years from the initial  date of the loan,
     with certain special provisions available for military reservists called to
     active duty. In the event of a participant's  termination of employment and
     subsequent default on the loan, any outstanding  balance will be considered
     a distribution  and will be taxable to the participant as prescribed by the
     Code.


(2)  SIGNIFICANT ACCOUNTING POLICIES

     Basis of  Accounting - The  financial  statements  of the Plan are prepared
     under the  accrual  method of  accounting  in  accordance  with  accounting
     principles generally accepted in the United States.

     Use of Estimates - The  preparation  of financial  statements in conformity
     with accounting principles generally accepted in the United States requires
     management  to make  estimates  and  assumptions  that affect the  reported
     amounts of net assets  available for benefits and changes  therein.  Actual
     results could differ from those estimates.

     Investment Risk - The Plan provides for  investments in various  investment
     securities,  which in  general,  are  exposed  to  various  risks,  such as
     interest rate, credit and overall market volatility risks.  Further, due to
     the level of risk associated with certain investment  securities,  it is at
     least  reasonably  possible  that  changes  in  the  values  of  investment
     securities  will  occur  in the  near  term and  that  such  changes  could
     materially  effect the  amounts  reported in the  statements  of net assets
     available for benefits.

     Investment  Valuation and Income  Recognition - The Plan's  investments are
     stated at fair value. Shares of registered  investment companies and common
     collective  trusts are valued at quoted market prices,  which represent the
     net asset value of shares held by the Plan at year-end.  The Company  stock
     is valued at its quoted market price.  Loans to participants  are valued at
     cost which  approximates fair value.  Purchases and sales of securities are
     recorded on a trade-date basis.  Interest income is recorded on the accrual
     basis. Dividends are recorded on the ex-dividend date.

     Payment  of  Benefits  -  Distributions   to  terminating  and  withdrawing

(6)  TAX STATUS

     The Plan obtained its latest  determination  letter dated November 5, 1999,
     in which the Internal  Revenue  Service stated that the Plan is a qualified
     plan under  provisions of Section  401(a) and is exempt from Federal Income
     taxes under  provisions  of Section  501(a) of the Code.  The Plan has been
     amended and restated  since  receiving its latest  determination  letter to
     reflect  recent  legislation.  The  Company has  requested a  determination
     letter which will cover the  amendments and is of the opinion that the Plan
     continues to be operated in compliance with the applicable  requirements of
     the Code and continues to be tax exempt.

     Taxes  on any  income  earned  on  investment  assets  attributable  to the
     participants  are deferred until the receipt of a distribution  pursuant to
     the  terms  of  the  Plan.   Prior  Company   contributions   and  employee
     contributions  to the  SMART  Savings  Program  are also  not  taxed to the
     participants until the receipt of a distribution.
