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, 2001, and the related  statement of changes in net assets available
for  benefits  for the year  then  ended.  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 audit.

     We conducted our audit 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 audit provides a reasonable  basis
for our opinion.

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

     Our audit was  performed  for the  purpose  of  forming  an  opinion on the
financial statements taken as a whole. The accompanying supplemental schedule of
assets  (held at end of year) as of  December  31,  2001,  and the  supplemental
schedule of reportable  transactions  for the year ended  December 31, 2001, 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, 2001 AND 2000


(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 April 2000, the Company completed the purchase of a titanium dioxide
         pigment  plant  in  Savannah,  Georgia,  from  Kemira  Oyj  of  Finland
         (Kemira).  Prior to the acquisition,  Kemira had a defined contribution
         plan, the Kemira Pigments,  Inc.  Employee Savings Plan, which included
         assets for both bargaining and non-bargaining  employees. The assets of
         the  non-bargaining  employees  were  transferred  into the Plan during
         February 2001.  The amount  transferred is shown as Transfer from prior
         trustee  on the  Statement  of  Changes  in Net  Assets  Available  for
         Benefits.  The  assets of the  bargaining  employees  will  remain in a
         separate plan,  the Kerr-McGee  Pigments  (Savannah),  Inc.  Employees'
         Savings  Plan  (Savannah  plan).  The assets of  employees  that change
         classification  from bargaining to non-bargaining  are transferred into
         the Plan and shown as Transfer  from  Savannah plan 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 2001,  the Company paid $15,000
         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  2001  totaled
         $12,162,000. Common stock of the Company held by the ESOP and allocated
         to participant's  accounts totaled 1,325,180 shares with a market value
         of  $72,677,000  at  December  31,  2001.   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 2001 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
         2001 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 during 2001:

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

                  composition of Standard & Poor's 500 Composite Index through
                  investments in common stocks.

                  Putnam  Asset  Allocation  Growth  Fund - asset allocation for

                  investments.


         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 salary,  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
         salary,  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 $10,500 for 2001 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
         salary,  after income taxes.  If a participant has authorized less than
         15% of their salary 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  national
         average  interest  rate  for  five-year  certificates  of  deposit  (as
         published  in The Wall Street  Journal),  plus 1.5%.  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
         6.37% for 2001. 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  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.

         Payment of Benefits -  Distributions  to  terminating  and  withdrawing
         participants are recorded when paid.

(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 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 until the receipt of a distribution.

(7)      SUBSEQUENT EVENTS

         In August 2001,  the Company  completed the  acquisition  of all of the
         outstanding shares of common stock of HS Resources, Inc. (HSR). HSR had
         a defined  contribution  plan, the HS Resources,  Inc.  401(k) & Profit
         Sharing Plan (HSR plan).  It is  anticipated  that the HSR plan will be
         merged  into the Plan  during  October  2002.  The total  effect of the
         merger on the Plan and its net assets is not currently known.
