                             ABOUT THIS PROSPECTUS

         This prospectus (the "Prospectus" ) is part of a Registration

                                  RISK FACTORS

         You should carefully consider the information contained in this
Prospectus and the following factors, among others, before purchasing the
Offered Securities.

MERGER-RELATED RISKS

         The merger between Oryx Energy Company ("Oryx") and us described below
under the "Recent Developments" section involves the integration of two
companies that have previously operated independently. The workforce is being
combined and reduced, offices are being consolidated and some employees are
relocating as part of this process. We expect that the combined company will,
as a result of its increased size and requirements, be able to consolidate its
purchasing and obtain more favorable prices from suppliers. However, its
ability to do so may be limited by changes in the purchasing power or practices
of its competitors and other market dynamics.

           There is no assurance that the two companies will be able to
integrate their operations without encountering difficulties or experiencing
the loss of key employees, or that the cost savings and synergies expected from
such integration will be realized.

EFFECTS OF VOLATILE PRODUCT PRICES AND MARKETS

         The results of operations of the company resulting from the
combination of Kerr-McGee and Oryx are highly dependent upon the prices of and
demand for oil and gas. Historically, the markets for oil and gas have been
volatile and are likely to continue to be volatile in the future. Accordingly,
the prices received by the combined company for its oil and gas production are
dependent upon numerous factors which will be beyond its control. These factors
include, but are not limited to, the level of ultimate consumer product demand,
governmental regulations and taxes, the price and availability of alternative
fuels, the level of imports and exports of oil and gas, and the overall
economic environment. Any significant decline in prices for oil and gas could
have a material adverse effect on the combined company's financial condition,
results of operations and quantities of reserves recoverable on an economic
basis. Should the industry experience significant price declines or other
adverse market conditions, the combined company may not be able to generate
sufficient cash flow from operations to meet its obligations and make planned
capital expenditures. In order to manage its exposure to price risks in the
sale of its oil and gas, the combined company may from time to time enter into
commodities futures or option contracts to hedge a portion of its crude oil and
natural gas sales volume, although we do not currently do so. Any such hedging
activities may prevent the combined company from realizing the benefits of
price increases above the levels reflected in such hedges.

FAILURE TO FUND CONTINUED CAPITAL EXPENDITURES COULD ADVERSELY AFFECT PROPERTIES

         If revenues of the combined company substantially decrease as a result
of lower oil and gas prices or otherwise, the combined company may have limited
ability to spend the capital necessary to replace its reserves or to maintain
production at current levels, resulting in a decrease in production over time.

         We expect that the combined company will continue to make capital
expenditures for the acquisition, exploration and development of oil and gas
reserves. Historically, each company financed these expenditures primarily with
cash flow from operations and proceeds from debt and equity financings, asset
sales and sales of partial interests in foreign concessions. We believe that,
after considering the amount of the combined company's debt, the combined
company will have sufficient cash flow from operations, available drawings
under its credit facilities and other debt financings to fund capital
expenditures. However, if the combined company's cash flow from operations is
not


                                       4
<PAGE>   6

sufficient to satisfy its capital expenditure requirements, there can be no
assurance that additional debt or equity financing or other sources of capital
will be available to meet these requirements. If the combined company is not
able to fund its capital expenditures, its interests in some of its properties
may be reduced or forfeited.

COSTS OF ENVIRONMENTAL LIABILITIES AND REGULATION COULD EXCEED ESTIMATES

         The combined company's current and former operations involve
management of regulated materials and are subject to various environmental laws
and regulations. These laws and regulations will obligate the combined company
to clean up various sites at which petroleum, chemicals, low-level radioactive
substances or other regulated materials have been disposed of or released. Some
of these sites have been designated Superfund sites by the U.S. Environmental
Protection Agency pursuant to the Comprehensive Environmental Response,
Compensation and Liability Act of 1980. The combined company is also a party to
legal proceedings involving environmental matters pending in various courts or
agencies.

         It is not possible for the companies to reliably estimate the amount
and timing of all future expenditures related to environmental matters because
of:
     o    the difficulty of estimating clean up costs;
     o    the uncertainty in quantifying liability under environmental laws
          that impose joint and several liability on all potentially
          responsible parties; and
     o    the continually changing nature of environmental laws and regulations.

  Although we believe that the combined company has established appropriate
reserves for clean up costs, due to the above-noted uncertainties, the combined
company could be required to record additional reserves in the future.

                                  THE COMPANY

         Kerr-McGee is an energy and chemical company with worldwide
operations. It explores for, develops, produces and markets crude oil and
natural gas and its chemical operations primarily produce and market titanium
dioxide pigment.

RECENT DEVELOPMENTS

         We have entered into a strategic combination with Oryx which creates
the fourth largest independent, nonintegrated oil and gas exploration and
production company based in the United States. The merger was completed on
February 26, 1999, upon the approval of the Shareholders of both companies. The
combined company retained the name Kerr-McGee Corporation, with executive
headquarters located in Oklahoma City, Oklahoma, and exploration and production
headquarters located in Houston, Texas.

                                USE OF PROCEEDS

         We will use the proceeds we receive from selling these Offered
Securities to pay off outstanding debt or for other general corporate purposes.
General corporate purposes may include capital expenditures, acquisitions, or
any other purposes that may be stated in the supplements. The proceeds may be
invested temporarily until they are used for their stated purpose.

RATIO OF EARNINGS TO FIXED CHARGES AND RATIO OF EARNINGS TO COMBINED FIXED
CHARGES AND PREFERRED STOCK DIVIDEND REQUIREMENTS

         The ratio of earnings to fixed charges for each of the periods
indicated is as follows(1):

<TABLE>

          --------                       --------
</TABLE>

(1) As of March 31, 1999, we had no outstanding preferred stock. Therefore,
unless otherwise stated in the Prospectus Supplement, the ratio of earnings to
fixed charges and the ratio of earnings to combined fixed charges and preferred
stock dividend requirements will be the same.

(2) Earnings were inadequate to cover fixed charges by $121 million in 1995,
$387 million in 1998 and $549 million for the 1998 Supplemental Ratio.

(3) The Supplemental 1998 ratio of earning to fixed charges is provided to
show the effect of the consummation of the merger between Kerr-McGee and Oryx.

         For purposes of computing the ratios, the earnings calculation is:
income from continuing operations + income taxes + fixed charges - capitalized
interest. Fixed charges calculation is: all interest + interest factor of
rental expense. The ratio of earnings to fixed charges was less than 1.0 for
the years ended December 31, 1995 and December 31, 1998.

                         DESCRIPTION OF DEBT SECURITIES

         The following description of the terms of the Debt Securities
summarizes certain general terms that will apply to the Debt Securities. The
description is not complete, and we refer you to the Indenture, a copy of which
is an exhibit to the Registration Statement of which this Prospectus is a part.
For your reference, in several cases below we have noted the section in the
Indenture that the paragraph summarizes. Capitalized items have the meanings
assigned to them in the Indenture. The referenced sections of the Indenture and
the definitions of capitalized terms are incorporated by reference in the
following summary.

         The Debt Securities will be issued under an Indenture dated as of
August 1, 1982 and supplemented by the First Supplemental Indenture dated
October 21, 1997 (the "Indenture") between Kerr-McGee and Citibank, N.A.
("Citibank"). The Indenture is incorporated by reference as an exhibit to the
Registration Statement filed with the SEC. This summary of the Indenture is
qualified by reference to the Indenture. You should refer to the Indenture in
addition to reading this summary. The summary is not complete and is subject to
the specific terms of the Indenture.

GENERAL

         Under the Indenture, we can issue an unlimited amount of Debt
Securities. The following amounts of Debt Securities are currently outstanding
under the Indenture:

          $150,000,000     -   6.625% Notes due
                               October 15, 2027
           150,000,000     -   7.125%  Debentures due
                               October 15, 2027

         Each time that we issue a new series of Debt Securities, the
supplement relating to that new series will specify the terms of those Debt
Securities, including:

          o    Designation, amount and denominations.
          o    Percentage of principal amount at which Debt Securities will be
               issued.
          o    Maturity date.
          o    Annual interest rate and payment dates.
          o    Terms and conditions of exchanging or converting Debt
               Securities for other securities.
          o    Redemption terms.
          o    Whether the Debt Securities will be senior, senior subordinated
               or subordinated.



                                       6
<PAGE>   8

         Payments relating to the Debt Securities generally will be paid at
Citibank's corporate trust office. However, we may elect to pay interest by
mailing checks directly to the registered holders of the Debt Securities. You
can transfer your Debt Securities at Citibank's corporate trust office.

         Unless otherwise described in the Prospectus Supplement for any
series, the Debt Securities will be unsecured and will rank on a parity with
all of our other unsecured and unsubordinated indebtedness.

         We will issue the Debt Securities in registered form without coupons.
You can transfer or exchange your Debt Securities without a service charge, but
we may require advance payment of any tax or other governmental transfer or
exchange charge.

                  voting stock either directly or indirectly. (Section 101)

         o        RESTRICTED SUBSIDIARY: Any subsidiary which we designate as a
                  Restricted Subsidiary or which owns or leases any Principal

                  land and fixtures), unless our Board of Directors feels that
                  the property or plant is not material to our total business.
                  The term does not include any facility acquired to control or

                  (Section 1008)

CERTAIN COVENANTS

         The Indenture includes the following covenants. These covenants use
certain terms that are defined above. The covenants for a series of Debt
Securities may differ from those described below. If they do, this will be
described in the supplement to this prospectus relating to that series.



                                       7

RESTRICTIONS ON SECURED DEBT

         After the date of the Indenture, if we incur or guarantee a debt
secured by either a mortgage on any of our Principal Property or on a
Restricted Subsidiary's stock or debt, we will secure the Debt Securities on
the same basis, unless the amount of the new debt plus the value of all sale
and leaseback transactions involving Principal Properties would not exceed 5%
of Consolidated Net Tangible Assets. The restrictions do not apply to debt
secured by the following:

         o        Mortgages on our property or the property of a Restricted
                  Subsidiary, which existed on the date of the Indenture.

         o        Mortgages on the property, stock or debt of a corporation
                  that existed when the corporation became a Restricted
                  Subsidiary.

         o        Mortgages on the property of a Restricted Subsidiary, which
                  only secures indebtedness owed by the Subsidiary to another
                  Restricted Subsidiary or us.

         o        Mortgages in favor of governmental bodies to secure progress,
                  advance or other payments.

         o        Mortgages on acquired property, stock or debt which existed
                  at the time of the acquisition (including acquisition through
                  merger or consolidation) and certain purchase money and
                  construction mortgages.

         o        Mortgages on our property or the property of a Restricted
                  Subsidiary to secure payment of the costs of operations
                  increase the production and disposition of minerals from the
                  property or indebtedness incurred to provide funds for such
                  purposes.

         o        Any extension, renewal or refunding of the foregoing.

         The listed debt will be excluded when computing our secured debt.

         The restrictions will not apply to sale and leaseback transactions if
the proceeds are applied to the retirement of Funded Debt. Secured debt will
not be deemed to be created by the transfer of an interest in property in the
form commonly referred to as a "production payment". (Sections 1008 and 1009)

RESTRICTIONS ON SALES AND LEASEBACKS

         We may not enter into any sale and leaseback transaction involving any
Principal Property after the date of the Indenture unless:

         o        The sale or transfer occurs within 120 days after
                  construction is complete and the Principal Property is fully
                  operational.

         o        We could mortgage the property under Section 1008 of the
                  Indenture for an amount equal to the proceeds of the sale and
                  leaseback transaction without securing the Debt Securities on
                  the same basis.

         o        We use an amount equal to the market value of the Principal
                  Property being leased to retire Funded Debt within 120 days.
                  This restriction will not apply to any sale and leaseback
                  transaction between us (or a Restricted Subsidiary) and a
                  Restricted Subsidiary, or involving the taking back of a
                  lease for a period of less than three years. (Section 1009)



                                       8
<PAGE>   10

MERGER AND CONSOLIDATION

         The Indenture generally permits a consolidation or merger between
Kerr-McGee and another corporation. It also permits the sale by Kerr-McGee of
all or substantially all of our property and assets. If this happens, the
resulting or acquiring corporation will assume all of our responsibilities and
liabilities under the Indentures. If the resulting or acquiring corporation has
outstanding Debt secured by a Mortgage on any Principal Property, or shares of
stock of a Restricted Subsidiary, the Debt Securities will be equally and
ratably secured with (or prior to) the Debt secured by such Mortgage. This
restriction will not apply if the Mortgage could be created pursuant to Section
1008 of the Indenture (see "Restrictions on Secured Debt" above) without
equally and ratable securing the Debt Securities. (Section 803)

MODIFICATION

         Generally, our rights and obligations and the holders' rights may be
modified if the holders of 66-2/3% of the outstanding Debt Securities consent.
However, no modification or amendment may occur without the consent of the
affected holder of the Debt Security if that modification or amendment would do
any of the following:

         o        Change the stated maturity date of the principal of, or any
                  installment of interest on, any of the holder's Debt
                  Security.

         o        Reduce the principal amount of, or the interest (or premium,
                  if any) on, the Debt Security (including in the case of a
                  discounted Debt Security, the amount payable upon
                  acceleration of maturity or provable in bankruptcy).

         o        Change the currency of payment of the Debt Security.

         o        Impair the right to institute suit for the enforcement of any
                  payment on the Debt Security or adversely affect the right of
                  repayment, if any, at the option of the holder.

         o        Reduce the percentage of holders of Debt Securities necessary
                  to modify or amend the Indenture.

         A modification which changes a covenant or provision expressly
included solely for the benefit of holders of one or more particular series
will not affect the rights of holders of Debt Securities of any other series.
(Section 902)

         Kerr-McGee or Citibank may make modifications without the consent of
the Debt Securities holders in order to do the following:

         o        Evidence that another corporation has succeeded to Kerr-McGee
                  and assumed our obligations.

         o        Convey security for the Debt Securities to Citibank.

         o        Add covenants, restrictions or conditions for the protection
                  of the Debt Security holders.




                                       9
<PAGE>   11

         o        Provide for the issuance of Debt Securities in coupon form.

         o        Establish the form or terms of Debt Securities of any series.

         o        Cure any ambiguity or correct any defect in the Indenture
                  which does not adversely affect the interests of a holder.

         o        Evidence the appointment of a successor trustee or more than
                  one trustee. (Section 901)

EVENTS OF DEFAULT

         In the Indenture, an Event of Default means any one of the following:

         o        Failure to pay interest on a Debt Security for 30 days;

         o        Failure to pay principal and premium, if any, when due;

         o        Failure to pay sinking fund installment when due;

         o        Failure to perform any other covenant in the Indenture that
                  continues for 60 days after receipt of notice; or

         o        Certain events in bankruptcy, insolvency or reorganization.

         An Event of Default relating to one series of Debt Securities does not
necessarily constitute an Event of Default with respect to any other series
issued under the Indenture. If an Event of Default exists with respect to a
series of Debt Securities, Citibank or the holders of at least 25% of the
outstanding Debt Securities of that series (or of all the outstanding Debt
Securities in the case of defaults due to failure to perform a covenant in the
Indenture or certain events in bankruptcy, insolvency, or reorganization) may
declare the principal of that series (or of all outstanding Debt Securities, as
the case may be) due and payable.

         Any Event of Default with respect to a particular series of Debt
Securities may be waived by the holders of a majority of the outstanding Debt
Securities of that series (or of all the outstanding Debt Securities as the
case may be), except for a failure to pay principal, premium or interest on the
Debt Security. (Sections 501, 502 and 508)

         Citibank may withhold notice to the holders of the Debt Securities of
any default (except in payment of principal, premium, interest or sinking fund
payment) if Citibank thinks it is in the interest of the holders.
(Section 602)

         Subject to the specific duties that arise under the Indenture if an
Event of Default exists, Citibank is not obligated to exercise any of its
rights or powers under the Indenture at the request of the holders of the Debt
Securities, unless they provide reasonable indemnity. (Sections 601 and 603).
Generally, the holders of a majority of the outstanding Debt Securities can
direct the proceeding for a remedy available to Citibank or for exercising any
power conferred on Citibank as the trustee. (Section 508)

TRUSTEE'S RELATIONSHIP WITH ISSUER

         Citibank has loaned us substantial amounts of money in the past and
may continue to do so. Citibank serves as a depository for us and performs
other services for us in the normal course of business. The Indenture provides
that we will indemnify Citibank against any loss, liability or expense incurred
that arises from the trust created by the Indenture unless the loss, liability
or expense results from Citibank's negligence or bad faith. (Section 607)



                                      10
<PAGE>   12

GLOBAL SECURITIES

         We may issue some of the Debt Securities as Global Securities that
will be deposited with a depository identified in the Prospectus Supplement.
Global Securities may be issued in either registered or bearer form and may be
either temporary or permanent. The Prospectus Supplement contains additional
information about depository arrangements.

         Registered Global Securities will be registered in the depositary's
name or in the name of its nominee. When we issue a Global Security, the
depositary will credit that amount of Debt Securities to the investors that
have accounts with the depository or its nominee. The underwriters or the Debt
Security holders' agent will designate the accounts to be credited, unless the
Debt Securities are offered and sold directly by Kerr-McGee, in which case, we
will designate the appropriate account to be credited.

         Investors who have accounts with a depository, and people who have an
interest in those institutions, are the beneficial owners of Global Securities
held by that particular depository.

         Kerr-McGee will not maintain records regarding ownership or the
transfer of Global Securities held by a depository or to nominee. If you are
the beneficial owner of Global Securities held by a depository, you must get
information directly from the depository.

         As long as a depositary is the registered owner of a Global Security,
that depository will be considered the sole owner of the Debt Securities
represented by that Global Security. Except as set forth below, beneficial
owners of Global Securities held by a depository will not be entitled to:

         o        Register the represented Debt Securities in their names;

         o        Receive physical delivery of the Debt Securities; or

         o        Be considered the owners or holders of the Global Security
                  under the Indenture.

Payments on Debt Securities registered in the name of a depositary or its
nominee will be made to the depositary or its nominee. (Section 203)

         When a depositary receives a payment, it must immediately credit the
accounts in amounts proportionate to the account holders' interests in the
Global Security. The beneficial owners of a Global Security should, and are
expected to, establish standing instructions and customary practices with their
investor that has an account with the depository, so that payments can be made
with regard to securities beneficially held for them, much like securities held
for the accounts of customers in bearer form or registered in "street name."

         A Global Security can only be transferred in whole by the depository
to a nominee of such depository, or to another nominee of a depository. If a
depositary is unwilling or unable to continue as a depository and we do not
appoint a successor depository within ninety (90) days, we will issue Debt
Securities in exchange for all of the Global Securities held by that
depository. In addition, we may eliminate all Global Securities at any time and
issue Debt Securities in exchange for them. Further, we may allow a depository
to surrender a Global Security in exchange for Debt Securities on any terms
that are acceptable to us and the depositary. (Section 307)

         If any of these events occur, we will execute and Citibank will
authenticate and deliver to the beneficial owners of the Global Security in
question a new registered security in an amount equal to and in exchange for
that person's beneficial interest in the exchanged Global Security. The
depository will receive a new Global Security in an amount equal to the
difference, if any, between the amount of the surrendered Global Security and
the amount of Debt Securities delivered to the beneficial owners. Debt
Securities issued in exchange for Global Securities will be registered in the
same names and in the same denominations as indicated by the depository's
records and in accordance with the instructions from its direct and indirect
participants.
(Section 307)



                                      11
<PAGE>   13

         The laws of certain jurisdictions require some people who purchase
securities to actually take physical possession of those securities. The
limitations imposed by these laws may impair your ability to transfer your
beneficial interests in a Global Security.

                         DESCRIPTION OF PREFERRED STOCK

GENERAL

         Our Certificate of Incorporation (the "Charter") authorizes our Board
of Directors or a committee of our Board of Directors (the "Board of
Directors") to cause preferred stock to be issued in one or more series,
without stockholder action. The Board of Directors is authorized to issue up to
40,000,000 shares of preferred stock, $1 par value per share (Preferred Stock),
and can determine the number of shares of each series, and the rights,
preference and limitations of each series. We may amend the Charter to increase
the number of authorized shares of preferred stock in a manner permitted by the
Charter and the Delaware General Corporation Law.

         The particular terms of any series of preferred stock being offered by
us under this shelf registration (the "Preferred Stock") will be described in
the Prospectus Supplement relating to that series of Preferred Stock. Those
terms may include:

         o        The number of shares of the series of Preferred Stock being
                  offered;

         o        The title and liquidation preference per share of that series
                  of the Preferred Stock;

         o        The purchase price of the Preferred Stock;

         o        The dividend rate (or method for determining such rates);

         o        The dates on which dividends will be paid;

         o        Whether dividends on that series of Preferred Stock will be
                  cumulative or noncumulative and, if cumulative, the dates
                  from which dividends shall commence to accumulate;

         o        Any redemption or sinking fund provisions applicable to that
                  series of Preferred Stock;

         o        Any conversion provisions applicable to that series of
                  preferred stock;

         o        Whether the Company has elected to offer Depositary Shares
                  with respect to that series of preferred stock; and

         o        Any additional dividend, liquidation, redemption, sinking
                  fund and other rights and restrictions applicable to that
                  series of Preferred Stock.

         If the terms of any series of Preferred Stock being offered differ
from the terms set forth herein, those terms will also be disclosed in the
Prospectus Supplement relating to that series of Preferred Stock. The following
summary is not complete. You should refer to the Certificate of Designations
relating to the series of the Preferred Stock for the complete terms of that
Preferred Stock. That Certificate of Designations will be filed with the SEC
promptly after the offering of the Preferred Stock.



                                      12
<PAGE>   14

         The Preferred Stock will, when issued, be fully paid and nonassesable.
Unless otherwise specified in the Prospectus Supplement, in the event we
liquidate, dissolve or wind-up our business, each series of Preferred Stock
will have the same rank as to dividends and distributions as each other series
of the Preferred Stock we may issue in the future. The Preferred Stock will
have no preemptive rights.

DIVIDEND RIGHTS

         Holders of Preferred Stock of each series will be entitled to receive,
when, as and if declared by the Board of Directors, cash dividends at the rates
and on the dates set forth in the Prospectus Supplement. Dividend rates may be
fixed or variable or both. Different series of Preferred Stock may be entitled
to dividends at different dividend rates or based upon different methods of
determination. Each dividend will be payable to the holders of record as they
appear on the stock books of the Company on record dates determined by the
Board of Directors. Dividends on any series of the Preferred Stock may be
cumulative or noncumulative, as specified in the Prospectus Supplement. If the
Board of Directors fails to declare a dividend on any series of Preferred Stock
for which dividends are noncumulative, then the right to receive that dividend
will be lost, and we will have no obligation to pay the dividend for that
dividend period, whether or not dividends are declared for any future dividend
period.

         No full dividends will be declared or paid on any series of Preferred
Stock, unless full dividends for the dividend period commencing after the
immediately preceding dividend payment date (and cumulative dividends still
owing, if any) have been or contemporaneously are declared and paid on all
other series of Preferred Stock which have the same rank as, or rank senior to,
that Preferred Stock. When those dividends are not paid in full, dividends will
be declared pro rata, so that the amount of dividends declared per share on
that series of Preferred Stock and on each other series of preferred stock
having the same rank as, or ranking senior to, that series of Preferred Stock
will in all cases bear to each other the same ratio that accrued dividends per
share on that series of Preferred Stock and the other preferred stock bear to
each other. In addition, generally, unless full dividends, including cumulative
dividends still owing, if any, on all outstanding shares of any series of
Preferred Stock have been paid, no dividends will be declared or paid on the
Common Stock and generally we may not redeem or purchase any Common Stock. No
interest, or sum of money in lieu of interest, will be paid in connection with
any dividend payment or payments which may be in arrears.

         Unless otherwise described in the Prospectus Supplement, the amount of
dividends payable for each dividend period will be computed by annualizing the
applicable dividend rate and dividing by the number of dividend periods in a
year, except that the amount of dividends payable for the initial dividend
period or any period shorter than a full dividend period shall be computed on
the basis of a 360-day year consisting of twelve 30-day months and, for any
period less than a full month, the actual number of days elapsed in the period.

RIGHTS UPON LIQUIDATION

         In the event we liquidate, dissolve or wind-up our affairs, either
voluntarily or involuntarily, the holders of each series of Preferred Stock
will be entitled to receive liquidating distributions in the amount set forth
in the Prospectus Supplement relating to each series of Preferred Stock, plus
an amount equal to accrued and unpaid dividends, if any, before any
distribution of assets is made to the holders of Common Stock. If the amounts
payable with respect to Preferred Stock of any series and any stock having the
same rank as that series of Preferred Stock are not paid in full, the



                                      13
<PAGE>   15

holders of Preferred Stock and of such other stock will share ratably in any
such distribution of assets in proportion to the full respective preferential
amounts to which they are entitled. After the holders of each series of
Preferred Stock and any stock having the same rank as the Preferred Stock are
paid in full, they will have no right or claim to any of our remaining assets.
Neither the sale of all or substantially all our property or business nor a
merger or consolidation by us with any other corporation will be considered a
dissolution, liquidation or winding up by us of our business or affairs.

REDEMPTION

         Any series of Preferred Stock may be redeemable, in whole or in part,
at our option. In addition, any series of Preferred Stock may be subject to
mandatory redemption pursuant to a sinking fund. The redemption provisions that
may apply to a series of Preferred Stock, including the redemption dates and
the redemption prices for that series, will be set forth in the Prospectus
Supplement.

         If a series of Preferred Stock is subject to mandatory redemption, the
Prospectus Supplement will specify the year we can begin to redeem shares of
the Preferred Stock, the number of shares of the Preferred Stock we can redeem
each year, and the redemption price per share. We may pay the redemption price
in cash, stock or in cash that we have received specifically from the sale of
our capital stock, as specified in the Prospectus Supplement. If the redemption
price is to be paid only from the proceeds of the sale of our capital stock,
the terms of the series of Preferred Stock may also provide that, if no such
capital stock is sold or if the amount of cash received is insufficient to pay
in full the redemption price then due, the series of Preferred Stock will
automatically be converted into shares of the applicable capital stock pursuant
to conversion provisions specified in the Prospectus Supplement.

         If fewer than all the outstanding shares of any series of Preferred
Stock are to be redeemed, whether by mandatory or optional redemption, the
Board of Directors will determine the method for selecting the shares to be
redeemed, which may be by lot or pro rata or by any other method determined to
be equitable. From and after the redemption date, dividends will cease to
accrue on the shares of Preferred Stock called for redemption and all rights of
the holders of those shares (except the right to receive the redemption price)
will cease.

         In the event that full dividends, including accrued but unpaid
dividends, if any, have not been paid on any series of Preferred Stock, we may
not redeem that series in part and we may not purchase or acquire any shares of
that series of Preferred Stock, except by any offer made on the same terms to
all holders of that series of Preferred Stock.

VOTING RIGHTS

         Except as indicated in the Prospectus Supplement, or except as
expressly required by applicable law, the holders of Preferred Stock will not
be entitled to vote.

DESCRIPTION OF COMMON STOCK


         As of the date of this prospectus, we are authorized to issue up to
300,000,000 shares of Common Stock. As of April 30, 1999, we had 86,372,748
shares of Common Stock issued.


         The following summary is not complete. You should refer to the
applicable provisions of the Charter, including the Certificates of
Designations pursuant to which any outstanding series of Preferred Stock may be
issued, and the Delaware General Corporation Law for a complete statement of
the terms and rights of the Common Stock.



                                      14
<PAGE>   16

         DIVIDENDS. Holders of Common Stock are entitled to receive dividends
when, as and if declared by the Board of Directors, out of funds legally
available for their payment (subject to the rights of holders of the preferred
stock, if any).

         VOTING RIGHTS. Each holder of Common Stock is entitled to one vote per
share. Subject to the rights, if any, of the holder of any series of preferred
stock pursuant to applicable law or the provision of the Certificate of
Designations creating that series, all voting rights are vested in the holders
of shares of Common Stock.

         RIGHTS UPON LIQUIDATION. In the event of our voluntary or involuntary
liquidation, dissolution or winding up, the holders of Common Stock will be
entitled to share equally in any of our assets available for distribution after
the payment in full of all debts and distributions and after the holders of all
series of outstanding preferred stock, if any, have received their liquidation
preferences in full.

         RIGHTS AGREEMENT. We have adopted a Rights Agreement, which provides
for the issuance of a right (a "Kerr-McGee Right") to the holder of each of our
shares of Common Stock. If anyone acquires 15% or more of our outstanding
Common Stock (an "Acquiring Person"), each holder of the Kerr-McGee Right
(other than the Acquiring Person) will be entitled to purchase additional
shares of Common Stock (or, in certain cases, other of our securities, or cash
or other property) having a current market value of two times the exercise
price of $215. Otherwise, prior to an Acquiring Person acquiring 50% or more of
the outstanding Common Stock, we may elect to issue a share of Common Stock in
exchange for each Kerr-McGee Right (other than Kerr-McGee Rights held by the
Acquiring Person). In addition, if we are acquired in a merger or other
business combination or 50% or more of our assets or earning power are sold,
each holder of a Kerr-McGee Right will be entitled to buy, at the exercise
price, common stock of the acquirer having a current market value of two times
the exercise price. At any time before there is an Acquiring Person, we can
redeem the Kerr-McGee Rights in whole, but not in part, for $0.01 per each
Kerr-McGee Right, or may amend the Rights Agreement in any way without the
consent of the holders of the Kerr-McGee Rights. We amended the Rights
Agreement so it was not triggered by the merger between us and Oryx.

         MISCELLANEOUS. The issued and outstanding shares of Common Stock are
fully paid and nonassessable. Holders of shares of Common Stock are not
entitled to preemptive rights. Shares of Common Stock are not convertible into
shares of any other class of capital stock.

DESCRIPTION OF WARRANTS

         We may issue warrants for the purchase of Debt Securities, Preferred
Stock or Common Stock ("Warrants"). We may issue warrants independently or
together with other securities. Each series of Warrants will be issued under a
separate warrant agreement (a "Warrant Agreement") to be entered into between
us and a bank or trust company, as warrant agent. You should refer to the
Warrant Agreement relating to the specific Warrants being offered for the
complete terms of the Warrant Agreement and the Warrants.

         Each Warrant will entitle the holder to purchase the principal amount
of Debt Securities, or the number of shares of Preferred Stock, or Common Stock
at the exercise price set forth in, or calculable as set forth in, the
Prospectus Supplement. The exercise price may be subject to adjustment upon the
occurrence of certain events, as set forth in the Prospectus Supplement. After
the close of business on the expiration date of the Warrant, unexercised
Warrants will become void. The place or places where, and the manner in which,
Warrants may be exercised shall be specified in the Prospectus Supplement.

                              PLAN OF DISTRIBUTION

         We may sell the Offered Securities through underwriters, dealers or
agents, or we may sell directly to one or more purchasers. The Prospectus
Supplement names any underwriters, states the purchase price and the proceeds
received by us, any underwriting discounts and other items constituting
underwriters' compensation, the initial public offering price, any discounts or
concessions to dealers, and any securities exchanges on which the Offered
Securities may be listed.

         If underwriters are used in the sale, the Offered Securities will be
acquired by the underwriters for their own account. The underwriters may resell
the Offered Securities in one or more transactions, including negotiated
transactions, at a fixed public offering price or at varying prices determined
at the time of sale. The Offered Securities may be offered through an
underwriting syndicate represented by many underwriters. The obligations of the
underwriters to purchase the Offered Securities will be subject to certain
conditions. The underwriters will be obligated to purchase all the Offered
Securities if any are purchased. Any initial public offering price and any
discounts or concessions allowed or reallowed or paid to dealers may be changed
from time to time.

         These Offered Securities may be sold directly by us or through agents.
Any agent will be named, and any commissions payable to that agent will be set
forth in the Prospectus Supplement. Unless otherwise indicated in the
Prospectus Supplement, any agent will be acting on a best efforts basis.

         We may authorize agents, underwriters or dealers to solicit offers by
specified institutions to purchase Offered Securities pursuant to delayed
delivery contracts providing for payment and delivery on a specified date in
the future. These contracts will be subject only to those conditions set forth
in the prospectus Supplement. The Prospectus Supplement will set forth the
commission payable for soliciting such contracts.

         We may agree to indemnify underwriters, dealers or agents against
certain civil liabilities, including liabilities under the Securities Act of
1933, and may also agree to contribute to payments which the underwriters,
dealers or agents may be required to make.

                                 LEGAL MATTERS


         Gregory F. Pilcher, Vice President and General Counsel, or another of
our lawyers, will issue an opinion about the legality of the securities for us.
Any underwriters will be advised about issues relating to this offering by their
own legal counsel.

         Arthur Andersen LLP, independent public accountants, audited our
financial statements and schedules incorporated by reference in this Prospectus
and at other places in the registration statement as indicated in their

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Article XXII of the ByLaws of the Company, as amended, provides for
indemnification of officers, directors and employees of the Company to the
extent authorized by the General Corporation Law of the State of Delaware.
Pursuant to Section 145 of the Delaware General Corporation Law, the Company
generally has the power to indemnify its present and former directors,
officers, employees and agents against expenses incurred by them in connection
with any suit to which they are, or are threatened to be made, a party by
reason of their serving in such positions so long as they acted in good faith
and in a manner they reasonably believed to be in, or not opposed to, the best
interests of a corporation, and with respect to any criminal action, they had
no reasonable cause to believe their conduct was unlawful. With respect to
suits by or in the right of a corporation, however, indemnification is not
available if such person is adjudged to be liable for negligence or misconduct
in the performance of his duty to the corporation unless the court determines
that indemnification is appropriate. In addition, a corporation has the power
to purchase and maintain insurance for such persons. The statute also expressly
provides that the power to indemnify authorized thereby is not exclusive of any
rights granted under any bylaw, agreement vote of stockholders or disinterested
directors, or otherwise.

         The above discussion of the Company's ByLaws and of Section 145 of the
Delaware General Corporation law is not intended to be exhaustive and is
respectively qualified in its entirety by such ByLaws and statute.

         Any underwriting agreement or agency agreement with respect to an
offering of securities registered hereunder will provide for indemnification of
Kerr-McGee Corporation and its officers and directors by the underwriters or
agents, as the case may be, against certain liabilities, including liabilities
under the Securities Act of 1933.

ITEM 17.  UNDERTAKINGS.

         The undersigned registrant does hereby undertake:

                  (1)      To file, during any period in which offers or sales
                           are being made, a post-effective amendment to this

                           (i)      To include any prospectus required by

                                    recent post-effective amendment thereof)
                                    which, individually or in the

                                    in the information set forth in the
                                    registration statement. Not withstanding
                                    the foregoing, any increase or decrease in
                                    volume of securities offered (if the total
                                    dollar value of securities offered would
                                    not exceed that which has been registered)
                                    and any deviation from the low or high end
                                    of the estimated maximum offering range may

                                    20% change in the maximum aggregate
                                    offering price set forth in the

                                    the effective registration statement;

                           (iii)    To include any material information with
                                    respect to the plan of distribution not
                                    previously disclosed in the registration
                                    statement or any material change to such
                                    information in the registration statement;

                           provided, however, that paragraphs (i) and (ii)
                           above do not apply if the information required to be
                           included in a post-effective amendment by those
                           paragraphs is contained in periodic reports filed by
                           the registrant pursuant to section 13 or section
                           15(d) of the Securities Exchange Act of 1934 that
                           are incorporated by reference in the registration
                           statement.

                   (2)     That, for the purpose of determining any liability
                           under the Securities Act of 1933, each such
                           post-effective amendment shall be deemed to be a new
                           registration statement relating to the securities
                           offered therein and the offering of such securities
                           at that time shall be deemed to be the initial bona
                           fide offering thereof.

                  (3)      To remove from registration by means of a
                           post-effective amendment any of the securities being
                           registered that remain unsold at the termination of
                           the offering.

         The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's Annual Report on Form 10-K pursuant to section 13(a) or section
15(d) of the Securities Exchange Act of 1934 (and, where applicable, each
filing of an employee benefit plan's annual report pursuant to section 15(d) of
the Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

         Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the Company pursuant to the provisions described in Item 15 above,
or otherwise, the Company has been advised that in the opinion of the
Securities and Exchange Commission, such indemnification is against public
policy as expressed in the Act and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the Company of expenses incurred or paid by a director, officer or
controlling person of the Company in the successful defense of any action, suit
or proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Company will, unless, in
the opinion of its counsel, the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

                                  May 24, 1999



Kerr-McGee Corporation
123 Robert S. Kerr Avenue
Oklahoma City, Oklahoma 73102

Ladies and Gentlemen:

     I am the Assistant General Counsel of Kerr-McGee Corporation, a Delaware
Corporation ("Kerr-McGee"), and I served as counsel in connection with the
Registration Statement on Form S-3 (the "Registration Statement") filed with the
Securities and Exchange Commission (the "Commission") under the Securities Act
of 1933, as amended (the "Act"), by Kerr-McGee which relates to preferred stock
of Kerr-McGee ("Preferred Stock"), common stock of Kerr-McGee ("Common Stock"),
unsecured debt securities of Kerr-McGee consisting of notes, debentures or other
evidences of indebtedness ("Debt Securities"), and warrants to purchase
Preferred Stock, Common Stock or Debt Securities ("Warrants") to be issued and
sold by Kerr-McGee from time to time pursuant to Rule 415 under the Act for an
aggregate initial offering price not to exceed $1,000,000,000 together with any
additional such securities that may be sold pursuant to a Registration Statement
filed under Rule 462 of the Act.

          In so acting, I have examined and relied upon the accuracy of
original, certified or photographic copies of such records, agreements,
certificates and other documents as I have deemed necessary or appropriate to
enable me to render the opinions set below. In all such examinations, I have
assumed the genuineness of all signatures, the legal capacity of natural
persons, the authenticity of all documents submitted to me as originals, the
conformity to original documents of all documents submitted to me as certified
or photostatic copies and the authenticity of the originals of such latter
documents.

        I have also assumed that (i) the Registration Statement, and any
amendments thereto (including post-effective amendments) and any additional
Registration Statement filed under Rule 462, will have become effective under
the Act, (ii) a prospectus supplement (a "Prospectus Supplement") will have
been prepared and filed with the Commission describing the Preferred Stock,
Common Stock, Debt Securities and/or Warrants offered thereby, (iii) all
Preferred Stock, Common Stock, Debt Securities and Warrants issued will be
issued and sold in compliance with applicable

federal and state securities laws and solely in the manner stated in the
Registration Statement and the appropriate Prospectus Supplement and (iv) a
definitive purchase, underwriting or similar agreement with respect to any
Preferred Stock, Common Stock, Debt Securities and/or Warrants offered will have
been duly authorized and validly executed and delivered by Kerr-McGee and the
other parties thereto.

     Based upon the foregoing, and subject to the qualifications and limitations
stated herein, I am of the opinion that:

     1.   With respect to Preferred Stock, when (i) the shares of Preferred
     Stock to be issued have been duly authorized by the shareholders of
     Kerr-McGee, (ii) the Board of Directors of Kerr-McGee (the "Board") has
     taken all necessary corporate action to approve the issuance and terms of
     such Preferred Stock, the terms of the offering thereof and related matters
     and (iii) such shares of Preferred Stock have been issued and delivered in
     accordance with the provisions of the applicable definitive purchase,
     underwriting or similar agreement approved by the Board, upon payment of
     the consideration therefor provided for therein, such shares of Preferred
     Stock will be legally issued, fully paid and nonassessable.

     2.   With respect to Common Stock, when (i) the shares of Common Stock to
     be issued have been duly authorized by the shareholders of Kerr-McGee, (ii)
     the Board has taken all necessary corporate action to approve the issuance
     and terms of such Common Stock, the terms of the offering thereof and
     related matters and (iii) such shares of Common Stock have been issued and
     delivered in accordance with the provisions of the applicable definitive
     purchase, underwriting or similar agreement approved by the Board, upon
     payment of the consideration therefor provided for therein, such shares of
     Common Stock will be legally issued, fully paid and nonassessable.

     3.   With respect to Debt Securities to be issued under the Indenture,
     dated as of August 1, 1982 and supplemented by the First Supplemental
     Indenture, dated May 7, 1996 (the "Indenture") between Kerr-McGee and
     Citibank, N.A., as Trustee (the "Trustee") when (i) the Indenture has been
     duly authorized, executed and delivered by the Trustee, (ii) the Indenture
     has been duly qualified under the Trust Indenture Act of 1939, as amended
     (the "Trust Indenture Act"), (iii) the Board has taken all necessary
     corporate action to approve the issuance and terms of such Debt Securities,
     the terms of the offering thereof and related matters and (iv) such Debt
     Securities have been duly executed, authenticated, issued and delivered in
     accordance with the provisions of the Indenture and the applicable
     definitive purchase, underwriting or similar agreement approved by the
     Board, upon payment of the consideration therefor provided for

     therein, such Debt Securities will be legally issued by Kerr-McGee and will
     constitute valid and legally binding obligations of Kerr-McGee, enforceable
     against Kerr-McGee in accordance with their terms.

     4.   With respect to the Warrants, when (i) the Board has taken all
     necessary corporate action to approve the creation of and issuance and
     terms of the Warrants, the terms of the offering thereof and related
     matters, (ii) any Warrant Agreement entered into in connection therewith
     (the "Warrant Agreement") has been duly authorized and validly executed and
     delivered by Kerr-McGee and (iii) the Warrants or certificates representing
     the Warrants have been duly executed, countersigned, registered and
     delivered in accordance with the applicable Warrant Agreement and the
     applicable definitive purchase, underwriting or similar agreement approved
     by the Board, upon payment of the consideration therefor provided for
     therein, the Warrants will be duly authorized and validly issued by
     Kerr-McGee and will constitute valid and legally binding obligations of
     Kerr-McGee, enforceable against Kerr-McGee in accordance with their terms.

     My opinions set forth in paragraphs 3 and 4 above are subject to the
effects of bankruptcy, insolvency, fraudulent conveyance, reorganization,
moratorium and other similar laws relating to or affecting creditors' rights
generally, general equitable principles (whether considered in a proceeding in
equity or at law) and an implied covenant of good faith and fair dealing.

     I hereby consent to the filing of this opinion of counsel as Exhibit 5.1 to
the Registration Statement and to the use of my name under the caption "Legal
Matters" in the Prospectus forming a part of the Registration Statement.

                                   Sincerely,


                                   /s/ DON HAGER
