Common Stock to holders of the DECS at maturity thereof pursuant to the terms of
the DECS), which registration statement is referred to in Section 2 of this
Agreement.

          Certain terms used in this Agreement are defined in Section 20 of this

     the Commission in the form on file with the Commission on its Effective

     Execution Time, shall contain only such specific additional information and
     other changes (beyond that contained in the Basic Kerr-McGee Prospectus and

     such date is not the Closing Date (a "settlement date"), the Final Kerr-
     McGee Prospectus (and any supplement thereto) will, comply in all material
     respects with the applicable requirements of the Act, the Exchange Act, and
     the Trust Indenture Act, and the respective rules thereunder; on the Kerr-
     McGee Effective Date, the Kerr-McGee Registration Statement did not or will

     Kerr-McGee Prospectus, if not filed pursuant to Rule 424(b), will not, and

     not, include any untrue statement of a material fact or omit to state a
     material fact necessary in order to make the statements therein, in the
     light of the circumstances under which they were made, not misleading;

     as to (A) that part of the Kerr-McGee Registration Statement which shall
     constitute the Statement of Eligibility and Qualification (Form T-1) under
     the Trust Indenture Act of the Trustee or (B) the information contained in

     Kerr-McGee Prospectus (or any supplement thereto) in reliance upon and in
     conformity with information furnished in writing to Kerr-McGee by or on

     Energy Prospectus in reliance upon and in conformity with information
     furnished in writing to Devon Energy by Kerr-McGee specifically for
     inclusion in the Devon Energy Prospectus.

          (iii) Kerr-McGee and each of its subsidiaries which are
     significant subsidiaries (as such term is defined in Rule 1-02 of
     Regulation S-X) (each, as set forth on Annex A attached hereto, a
     "Kerr-McGee Significant Subsidiary," and collectively, the "Kerr-McGee
     Significant Subsidiaries") have been duly incorporated and are validly
     existing as corporations in good standing under the laws of the

     their properties and conduct their businesses as described in the Final
     Kerr-McGee Prospectus, and are duly qualified to do business as foreign

     properties] of Kerr-McGee and its subsidiaries, taken as a whole;

          (iv) All the outstanding shares of capital stock of each Kerr-
     McGee Significant Subsidiary have been duly authorized and validly issued
     and are fully paid and nonassessable, and, except as otherwise set forth in

     Significant Subsidiaries are owned by Kerr-McGee either directly or through
     wholly owned subsidiaries free and clear of any perfected security interest
     or any other security interests, claims, liens or encumbrances;

          (v) The Indenture has been duly authorized and, if the Effective Time
     of the Kerr-McGee Registration Statement is prior to the execution and
     delivery of this Agreement, has been or otherwise upon such Effective Time
     will be duly qualified under the Trust Indenture Act with respect to the
     DECS offered thereby; the DECS have been duly authorized; and when DECS
     offered are delivered and paid for pursuant to this Agreement on each
     Closing Date, the Indenture will have been duly executed and delivered,
     such DECS will have been duly executed, authenticated, issued and delivered
     and will conform to the description thereof contained in the Final Kerr-
     McGee Prospectus and the Indenture and such DECS will constitute valid and
     legally binding obligations of Kerr-McGee, enforceable in accordance with
     their terms, subject to bankruptcy insolvency, fraudulent transfer,

     relating to or affecting creditors' rights and to general equity
     principles.

          (vi) The DECS have been approved for listing on The New York Stock
     Exchange, subject to notice of issuance.

          (vii) There is no franchise, contract or other document of a character
     required to be described in the Kerr-McGee Registration Statement or Final
     Kerr-McGee Prospectus, or to be filed as an exhibit thereto, which is not

     Prospectus under the caption "Description of Debt Securities" and in the
     Final Kerr-McGee Prospectus Supplement under the captions "Description of
     DECS" and "Certain United States Federal Income Tax Consequences" fairly

          (viii) This Agreement has been duly authorized, executed and delivered

                                       4


     Common Stock by the Underwriters in the manner contemplated herein and in

          (xi) Neither the issue and sale of the DECS nor the consummation of

     assets of Kerr-McGee or any of its Kerr-McGee Significant Subsidiaries
     pursuant to, (i) the charter or by-laws of Kerr-McGee or any of its Kerr-
     McGee Significant Subsidiaries, (ii) the terms of any material indenture,
     contract, lease, mortgage, deed of trust, note agreement, loan agreement or
     other agreement, obligation, condition, covenant or instrument to which
     Kerr-McGee or any of its Kerr-McGee Significant Subsidiaries is a party or
     bound or to which its or their property is subject, or (iii) any statute,
     law, rule, regulation, judgment, order or decree applicable to Kerr-McGee
     or any of its Kerr-McGee Significant Subsidiaries of any court, regulatory
     body, administrative agency, governmental body, arbitrator or other
     authority having jurisdiction over Kerr-McGee or any of its Kerr-McGee
     Significant Subsidiaries or any of its or their properties.

          (xii) No action, suit or proceeding by or before any court or
     governmental agency, authority or body or any arbitrator involving Kerr-
     McGee or any of its subsidiaries or its or their property is pending or, to
     the best knowledge of Kerr-McGee, threatened that (i) could reasonably be
     expected to have a material adverse effect on the performance of this
     Agreement or the consummation of any of the transactions contemplated
     hereby or (ii) could reasonably be expected to have a material adverse
     effect on the [financial condition, results of operations, prospects,
     earnings or properties] of Kerr-McGee and its subsidiaries, taken as a
     whole, whether or not arising from transactions in the ordinary course of
     business, except as set forth in or contemplated in the Final Kerr-McGee
     Prospectus (exclusive of any supplement thereto).

          (xiii) Neither Kerr-McGee nor any Kerr-McGee Significant Subsidiary is
     in violation or default of (i) any provision of its charter or bylaws, (ii)
     the terms of any indenture, contract, lease, mortgage, deed of trust, note
     agreement, loan agreement or other agreement, obligation, condition,
     covenant or instrument to which it is a party or bound or to which its
     property is subject, except if such violation or default with respect to
     this clause (ii) could not reasonably be expected to have a material
     adverse effect on the [financial condition, results of operations,
     prospects, earnings or properties] of Kerr-McGee and its subsidiaries,
     taken as a whole, or (iii) any statute, law, rule, regulation, judgment,
     order or decree of any court, regulatory body, administrative agency,
     governmental body, arbitrator or other authority having jurisdiction over
     Kerr-McGee or such Kerr-McGee Significant Subsidiary or any of its
     properties, as applicable, except with respect to this clause (iii) such as
     could not reasonably be expected to have a material adverse effect on the
     [financial condition, results of operations, prospects, earnings or
     properties] of Kerr-McGee and its subsidiaries, taken as a whole.

          (xiv) Kerr-McGee and its subsidiaries possess all licenses,
     certificates, permits and other authorizations issued by the appropriate
     federal, state or foreign regulatory authorities necessary to conduct their
     respective businesses, and neither Kerr-McGee nor

                                       5


     any such subsidiary has received any notice of proceedings relating to
     the revocation or modification of any such certificate, authorization or
     permit which, singly or in the aggregate, if the subject of an unfavorable
     decision, ruling or finding, would have a material adverse effect on the
     [financial condition, results of operations, prospects, earnings or
     properties] of Kerr-McGee and its subsidiaries, taken as a whole, whether
     or not arising from transactions in the ordinary course of business, except
     as set forth in or contemplated in the Final Kerr-McGee Prospectus
     (exclusive of any supplement thereto).

          (xv) [Kerr-McGee and its subsidiaries are (i) in compliance with any
     and all applicable foreign, federal, state and local laws and regulations
     relating to the protection of human health and safety, the environment or
     hazardous or toxic substances or wastes, pollutants or contaminants
     ("Environmental Laws"), (ii) have received and are in compliance with all
     permits, licenses or other approvals required of them under applicable
     Environmental Laws to conduct their respective businesses and (iii) have
     not received notice of any actual or potential liability for the
     investigation or remediation of any disposal or release of hazardous or
     toxic substances or wastes, pollutants or contaminants, except where such
     non-compliance with Environmental Laws, failure to receive required
     permits, licenses or other approvals, or liability would not, individually
     or in the aggregate, have a material adverse effect on the [financial
     condition, results of operations, prospects, earnings or properties] of
     Kerr-McGee and its subsidiaries, taken as a whole, whether or not arising
     from transactions in the ordinary course of business, except as set forth
     in or contemplated in the Final Kerr-McGee Prospectus (exclusive of any
     supplement thereto). Except as set forth in the Final Kerr-McGee
     Prospectus, neither Kerr-McGee nor any of the subsidiaries has been named
     as a "potentially responsible party" under the Comprehensive Environmental
     Response, Compensation, and Liability Act of 1980, as amended.

          (xvi) In the ordinary course of its business, Kerr-McGee periodically
     reviews the effect of Environmental Laws on the business, operations and
     properties of Kerr-McGee and its subsidiaries, in the course of which it
     identifies and evaluates associated costs and liabilities (including,
     without limitation, any capital or operating expenditures required for
     clean-up, closure of properties or compliance with Environmental Laws, or
     any permit, license or approval, any related constraints on operating
     activities and any potential liabilities to third parties). On the basis of
     such review, Kerr McGee has reasonably concluded that such associated costs
     and liabilities would not, singly or in the aggregate, have a material
     adverse effect on the [financial condition, results of operations,
     prospects, earnings or properties] of Kerr McGee and its subsidiaries,
     taken as a whole, whether or not arising from transactions in the ordinary
     course of business, except as set forth in or contemplated in the Final
     Kerr-McGee Prospectus (exclusive of any supplement thereto).]

          (xvii) The subsidiaries listed on Annex A attached hereto are the only
     significant subsidiaries of Kerr-McGee as defined by Rule 1-02 of
     Regulation S-X.

          (xviii) Kerr-McGee and its subsidiaries have implemented a
     comprehensive, detailed program to analyze and address the risk that the
     computer hardware and software used by them may be unable to recognize and
     properly execute date-sensitive functions involving

                                       6


     certain dates prior to and any dates after December 31, 1999 (the "Year
     2000 Problem"), and has determined that such risk will be remedied on a
     timely basis without material expense and will not have a material adverse
     effect upon the financial condition and results of operations of Kerr-McGee
     and its subsidiaries, taken as a whole; and Kerr-McGee believes, after due
     inquiry, that each supplier, vendor, customer or financial service
     organization used or serviced by Kerr-McGee and its subsidiaries has
     remedied or will remedy on a timely basis the Year 2000 Problem, except to
     the extent that a failure to remedy by any such supplier, vendor, customer
     or financial service organization would not have a material adverse effect
     on Kerr-McGee and its subsidiaries, taken as a whole. Kerr-McGee is in
     compliance in all material respects with the Commission Release Nos. 33-
     7558 and 33-7609 related to Year 2000 compliance, as amended or
     supplemented to date.

          (xix) Subsequent to the respective dates as of which information is
     presented in the Kerr-McGee Registration Statement and the Final Kerr-McGee
     Prospectus, except as otherwise stated therein, there has been no material
     adverse change or any development involving a prospective material adverse
     change in the condition (financial or otherwise), business, properties or
     results of operations of Kerr-McGee and its subsidiaries taken as a whole.

          (xx) Kerr-McGee has not taken and will not take, directly or
     indirectly, any action designed to or which has constituted or which might
     reasonably be expected to cause or result, under the Exchange Act or
     otherwise, in stabilization or manipulation of the price of any security of
     Devon Energy to facilitate the sale or resale of the DECS or the Devon
     Energy Common Stock and has not effected any sales of Devon Energy Common
     Stock which, if effected by the issuer, would be required to be disclosed
     in response to Item 701 of Regulation S-K.

          (xxi) If Kerr-McGee elects to exchange the DECS for the Shares on the
     Exchange Date (as defined in the DECS), then on such Exchange Date it will
     be the record and beneficial owner of the Shares to be sold by it hereunder
     free and clear of all liens, encumbrances, equities and claims and will
     have duly indorsed such Shares in blank, and, assuming that each holder of
     DECS acquires its interest in the Shares it receives on the Exchange Date
     from Kerr McGee without notice of any adverse claim (within the meaning of
     Section 8-105 of the New York Uniform Commercial Code ("UCC")), upon sale
     and delivery of, and payment for, such Shares, as provided herein and in
     the terms of the DECS, each such holder will own the Shares, free and clear
     of all liens, encumbrances, equities and claims whatsoever.

          (b)  In respect of any statements in or omissions from the Devon
Energy Registration Statement or the Devon Energy Prospectus or any supplements
thereto made in reliance upon and in conformity with information furnished in
writing to Devon Energy by Kerr-McGee specifically for inclusion therein,
Kerr-McGee makes the same representations and warranties to Devon Energy as
Kerr-McGee makes to each Underwriter under paragraph (a)(ii) of this Section 1.

                                       7

          (a)  Devon Energy meets the requirements for use of Form S-3 under the
     Act and has prepared and filed with the Commission a registration statement

     prospectus, for registration under the Act of the offering and sale of the
     Shares.  Devon Energy may have filed one or more amendments thereto,

     statement, including the form of final prospectus or (2) after the Devon
     Energy Effective Date of such registration statement, a final prospectus in
     accordance with Rules 430A and 424(b).  In the case of clause (2), Devon
     Energy has included in such registration statement, as amended at the Devon
     Energy Effective Date, all information (other than Rule 430A Information)
     required by the Act and the rules thereunder to be included in such
     registration statement and the Devon Energy Prospectus with respect to the
     Shares and the offering thereof.  As filed, such amendment and form of
     final prospectus, or such final prospectus, shall contain all Rule 430A
     Information, together with all other such required information with respect
     to the Shares and the offering thereof, and, except to the extent the
     Representatives shall agree in writing to a modification, shall be in all
     substantive respects in the form furnished to you prior to the Execution
     Time or, to the extent not completed at the Execution Time, shall contain
     only such specific additional information and other changes (beyond that
     contained in the latest Preliminary Devon Energy Prospectus) as Devon
     Energy has advised you, prior to the Execution Time, will be included or
     made therein.  Any reference herein to the Devon Energy Registration
     Statement, Preliminary Devon Energy Prospectus or the Devon Energy
     Prospectus shall be deemed to refer to and include the documents

     were filed under the Exchange Act on or before the Devon Energy Effective
     Date or the issue date of a Preliminary Devon Energy Prospectus or the

     the terms "amend," "amendment" or "supplement" with respect to the Devon
     Energy Registration Statement, any Preliminary Devon Energy Prospectus or

     Statement did or will, and when the Devon Energy Prospectus is first filed
     (if required) in accordance with Rule 424(b) and on the Closing Date and on
     any settlement date (as defined below), the Devon Energy Prospectus (and
     any supplements thereto) will, comply in all material respects with the
     applicable requirements of the Act, the Exchange Act and the respective
     rules thereunder; on the Devon Energy Effective Date and at the Execution
     Time, the Devon Energy Registration Statement did not or will not contain
     any untrue statement of a material fact or omit to state any material fact

     therein or necessary in order to make the statements therein not
     misleading; and, on the Devon Energy Effective Date, the Devon Energy
     Prospectus, if not filed pursuant to Rule 424(b), will not, and on the date
     of any filing pursuant to Rule 424(b) and on the Closing Date, the Devon
     Energy Prospectus (together with any supplement thereto) will not, include
     any untrue statement of a material fact or omit to state a material fact
     necessary in order to make the statements therein, in the light of the
     circumstances under which they were made, not misleading; provided,
     however, that Devon Energy makes no representations or warranties as to the
     information contained in or omitted from the Devon Energy Registration
     Statement, or the Devon Energy Prospectus (or any supplement thereto) in
     reliance upon and in conformity with information furnished in writing to
     Devon Energy (i) by or on behalf of any Underwriter through the
     Representatives specifically for inclusion in the Devon Energy Registration
     Statement or the Devon Energy Prospectus (or any supplement thereto) or
     (ii) by Kerr-McGee, in either case, specifically for inclusion in the Devon
     Energy Registration Statement or the Devon Energy Prospectus (or any
     supplement thereto).

          (c)  Each of Devon Energy and each of its subsidiaries which are
     significant subsidiaries (as such term is defined in Rule 1-02 of
     Regulation S-X) (each, as set forth on Annex B attached hereto, a "Devon
     Energy Significant Subsidiary," and collectively, the "Devon Energy
     Significant Subsidiaries") has been duly incorporated and is validly
     existing as a corporation in good standing under the laws of the
     jurisdiction in which it is chartered or organized with full corporate
     power and authority to own or lease, as the case may be, and to operate its
     properties and conduct its business as described in the Devon Energy
     Prospectus and is duly qualified to do business as a foreign corporation
     and is in good standing under the laws of each jurisdiction in which the
     failure so to qualify would have a material adverse effect on the
     [financial condition, results of operations, prospects, earnings or
     properties] of Devon Energy and its subsidiaries, taken as a whole.

          (d)  Devon Energy's authorized equity capitalization is as set forth
     in the Devon Energy Prospectus; the capital stock of Devon Energy conforms
     in all material respects to the description thereof contained in the Devon
     Energy Prospectus; the outstanding shares of Devon Energy Common Stock have
     been duly and validly authorized and issued and are fully paid and
     nonassessable; the Shares have been duly and validly authorized, and, when
     issued and delivered to and paid for by the Underwriters pursuant to this
     Agreement, will be fully paid and nonassessable; the Shares are duly
     listed, and admitted and authorized for trading, subject to official notice
     of issuance, on the American Stock Exchange (the "AMEX"); the certificates
     for the Shares are in valid and sufficient form; the holders of outstanding
     shares of capital stock of Devon Energy are not entitled to preemptive or
     other rights to subscribe for the Shares; and, except as set forth in the
     Devon Energy Prospectus, no options, warrants or other rights to purchase,
     agreements or other obligations to issue, or rights to convert any
     obligations into or exchange any securities for, shares of capital stock of
     or ownership interests in Devon Energy are outstanding.

          (e)   All of the outstanding shares of capital stock of each Devon
     Energy Significant Subsidiary have been duly and validly authorized and
     issued and are fully

                                       9


     paid and nonassessable and, except as otherwise set forth in the Devon
     Energy Prospectus, all outstanding shares of capital stock of the Devon
     Energy Significant Subsidiaries are owned by Devon Energy either directly
     or through wholly-owned subsidiaries free and clear of any perfected
     security interests, claims, liens or encumbrances.

          (f)  This Agreement has been duly authorized, executed and delivered
     by Devon Energy and constitutes a valid and binding obligation of Devon
     Energy enforceable in accordance with its terms, subject to applicable
     bankruptcy, insolvency, moratorium or other similar laws relating to
     creditors' rights and general principles of equity.

          (g)  No holders of securities of Devon Energy, other than Kerr-McGee,
     have rights to the registration of such securities under the Devon Energy
     Registration Statement.

          (h)  Devon Energy and its subsidiaries are (i) in compliance with any
     and all applicable foreign, federal, state and local laws and regulations
     relating to the protection of human health and safety, the environment or
     hazardous or toxic substances or wastes, pollutants or contaminants
     ("Environmental Laws"), (ii) have received and are in compliance with all
     permits, licenses or other approvals required of them under applicable
     Environmental Laws to conduct their respective businesses and (iii) have
     not received notice of any actual or potential liability for the
     investigation or remediation of any disposal or release of hazardous or
     toxic substances or wastes, pollutants or contaminants, except where such
     non-compliance with Environmental Laws, failure to receive required
     permits, licenses or other approvals, or liability would not, individually
     or in the aggregate, have a material adverse effect on the [financial
     condition, results of operations, prospects, earnings or properties] of
     Devon Energy and its subsidiaries, taken as a whole, whether or not arising
     from transactions in the ordinary course of business, except as set forth
     in or contemplated in the Devon Energy Prospectus (exclusive of any
     supplement thereto).  Except as set forth in the Devon Energy Prospectus,
     neither Devon Energy nor any of the subsidiaries has been named as a
     "potentially responsible party" under the Comprehensive Environmental
     Response, Compensation, and Liability Act of 1980, as amended.

          (i)  In the ordinary course of its business, Devon Energy periodically
     reviews the effect of Environmental Laws on the business, operations and
     properties of Devon Energy and its subsidiaries, in the course of which it
     identifies and evaluates associated costs and liabilities (including,
     without limitation, any capital or operating expenditures required for
     clean-up, closure of properties or compliance with Environmental Laws, or
     any permit, license or approval, any related constraints on operating
     activities and any potential liabilities to third parties).  On the basis
     of such review, Devon Energy has reasonably concluded that such associated
     costs and liabilities would not, singly or in the aggregate, have a
     material adverse effect on the [financial condition, results of operations,
     prospects, earnings or properties] of Devon Energy and its subsidiaries,
     taken as a whole, whether or not arising from transactions in the ordinary
     course of business, except as set forth in or contemplated in the Devon
     Energy Prospectus (exclusive of any supplement thereto).

                                       10


          (j)  No action, suit or proceeding by or before any court or
     governmental agency, authority or body or any arbitrator involving the
     Company or any of its subsidiaries or its or their property is pending or,
     to the best knowledge of the Company, threatened that (i) could reasonably
     be expected to have a material adverse effect on the performance of this
     Agreement or the consummation of any of the transactions contemplated
     hereby or (ii) could reasonably be expected to have a material adverse
     effect on the [financial condition, results of operations, prospects,
     earnings or properties] of the Company and its subsidiaries, taken as a
     whole, whether or not arising from transactions in the ordinary course of
     business, except as set forth in or contemplated in the Devon Energy
     Prospectus (exclusive of any supplement thereto).

          (k)  No consent, approval, authorization, filing with or order of any
     court or governmental agency or body is required in connection with the
     transactions contemplated herein, except such as have been obtained under
     the Act and such as may be required under the blue sky laws of any
     jurisdiction in connection with the purchase and distribution of the Shares
     by the Underwriters in the manner contemplated herein and in the Final
     Kerr-McGee Prospectus or the Devon Energy Prospectus.

          (l)  Neither the issue and sale of the Shares nor the consummation by
     Devon Energy of any other of the transactions herein contemplated nor the
     fulfillment of the terms hereof will conflict with, result in a breach or
     violation or imposition of any material lien, charge or encumbrance upon
     any property or assets of Devon Energy or any of its Devon Energy
     Significant Subsidiaries pursuant to, (i) the charter or by-laws of Devon
     Energy or any of its Devon Energy Significant Subsidiaries, (ii) the terms
     of any indenture, contract, lease, mortgage, deed of trust, note agreement,
     loan agreement or other agreement, obligation, condition, covenant or
     instrument to which Devon Energy or any of its Devon Energy Significant
     Subsidiaries is a party or bound or to which its or their property is
     subject, or (iii) any statute, law, rule, regulation, judgment, order or
     decree applicable to Devon Energy or any of its Devon Energy Significant
     Subsidiaries of any court, regulatory body, administrative agency,
     governmental body, arbitrator or other authority having jurisdiction over
     Devon Energy or any of its Devon Energy Significant Subsidiaries or any of
     its or their properties.

          (m)  Devon Energy and its subsidiaries possess all licenses,
     certificates, permits and other authorizations issued by the appropriate
     federal, state or foreign regulatory authorities necessary to conduct their
     respective businesses as presently conducted, except where the failure to
     possess such licenses, certificates, permits or other authorizations would
     not, individually or in the aggregate, have a material adverse effect on
     the [financial condition, results of operations, prospects, earnings or
     properties] of Devon Energy and its subsidiaries, taken as a whole, and
     neither Devon Energy nor any such subsidiary has received any notice of
     proceedings relating to the revocation or modification of any such
     certificate, authorization or permit which, singly or in the aggregate, if
     the subject of an unfavorable decision, ruling or finding, would have a
     material adverse effect on the [financial condition, results of operations,
     prospects, earnings or properties] of Devon Energy and its subsidiaries,
     taken as a whole, whether or not arising from transactions in the ordinary
     course of business, except as set forth in or contemplated in the Devon
     Energy Prospectus (exclusive of any supplement thereto).

                                       11


          (o)  Devon Energy is not an "investment company" as defined in the
     Investment Company Act of 1940, as amended.

          (p)  Devon Energy and its subsidiaries have implemented a
     comprehensive, detailed program to analyze and address the risk that the
     computer hardware and software used by them may be unable to recognize and
     properly execute date-sensitive functions involving certain dates prior to
     and any dates after December 31, 1999 (the "Year 2000 Problem"), and has
     determined that such risk will be remedied on a timely basis without
     material expense and will not have a material adverse effect upon the
     financial condition and results of operations of Devon Energy and its
     subsidiaries, taken as a whole; and Devon Energy believes, after due
     inquiry, that each supplier, vendor, customer or financial service
     organization used or serviced by Devon Energy and its subsidiaries has
     remedied or will remedy on a timely basis the Year 2000 Problem, except to
     the extent that a failure to remedy by any such supplier, vendor, customer
     or financial service organization would not have a material adverse effect
     on Devon Energy and its subsidiaries, taken as a whole.  Devon Energy is in
     compliance in all material respects with the Commission Release Nos.
     33-7558 and 33-7609 related to Year 2000 compliance, as amended or
     supplemented to date.

          (q)  The Devon Energy Common Stock is duly listed and admitted for
     trading on the AMEX.

         3.  Purchase and Sale.  (a)  Subject to the terms and conditions and in
reliance upon the representations and warranties herein set forth, Kerr-McGee
agrees to sell to each Underwriter, and each Underwriter agrees, severally and
not jointly, to purchase from Kerr-McGee, the number of DECS set forth opposite
that Underwriter's name on Schedule I hereto, at a price of $______ per DECS,
plus accrued interest, if any, on the DECS from _______, 1999 to the Closing
Date.

          (b)  Subject to the terms and conditions and in reliance upon the
representations and warranties herein set forth, Kerr-McGee hereby grants an
option to the several Underwriters to purchase, severally and not jointly, up to
_______ of the Option DECS at the same purchase price as the Underwriters shall
pay for the Underwritten DECS.  Said option may be exercised only to cover over-
allotments in the sale of the Underwritten DECS by the Underwriters.  Said
option may be exercised in whole or in part at any time (but not more than once)
on or before the 30th day after the date of the Final Kerr-McGee Prospectus upon
written or telegraphic notice by the Representatives to Kerr-McGee setting forth
the number of the Option DECS as to which the several Underwriters are
exercising the option and the settlement date.  The number of the Option DECS to
be purchased by each Underwriter shall be the same percentage of the total
number of the Option DECS to be purchased by the several Underwriters as such
Underwriter is purchasing of the Underwritten DECS, subject to such adjustments
as you in your absolute discretion shall make to eliminate any fractional Option
DECS.

          4.  Delivery and Payment.  Delivery of and payment for the
Underwritten DECS and the Option DECS (if the option provided for in Section
3(b) hereof shall have been exercised on or before the third Business Day prior
to the Closing Date) shall be made at 10:00 AM New York City time, on
__________, 1999, or at such time on such later date not more than three

                                       12


Business Days after the foregoing date as the Representatives shall designate,
which date and time may be postponed by agreement between the Representatives
and Kerr-McGee or as provided in Section 11 hereof (such date and time of
delivery and payment for the DECS being herein called the "Closing Date").
Delivery of the DECS shall be made to the Representatives for the respective
accounts of the several Underwriters against payment by the several Underwriters
through the Representatives of the purchase price thereof to or upon the order
of Kerr-McGee by wire transfer payable in same-day funds to an account specified
by Kerr-McGee.  Delivery of the DECS shall be made through the facilities of The
Depository Trust Company unless the Representatives shall otherwise instruct.

          If the option provided for in Section 3(b) hereof is exercised after
the third Business Day prior to the Closing Date, Kerr-McGee will deliver the
Option DECS (at the expense of Kerr-McGee) to the Representatives, at 388
Greenwich Street, New York, New York, on the date specified by the
Representatives (which shall be within three Business Days after exercise of
said option) for the respective accounts of the several Underwriters, against
payment by the several Underwriters through the Representatives of the purchase
price thereof to or upon the order of Kerr-McGee by wire transfer payable in
same-day funds to an account specified by Kerr-McGee.  If settlement for the
Option DECS occurs after the Closing Date, Kerr-McGee and Devon Energy will
deliver to the Representatives on the settlement date for the Option DECS, and
the obligation of the Underwriters to purchase the Option DECS shall be
conditioned upon receipt of, supplemental opinions, certificates and letters
confirming as of such date the opinions, certificates and letters delivered on
the Closing Date pursuant to Section 7 hereof.

          5.  Offering by Underwriters.  It is understood that the several
Underwriters propose to offer the DECS for sale to the public as set forth in
the Final Kerr-McGee Prospectus.

          6.  Agreements of Kerr-McGee.

          Kerr-McGee agrees with the several Underwriters that:

          (a)  Prior to the termination of the offering of the DECS, Kerr-McGee
     will not file any amendment of the Kerr-McGee Registration Statement or
     supplement (including the Final Kerr-McGee Prospectus or any Preliminary
     Final Kerr-McGee Prospectus) to the Basic Kerr-McGee Prospectus unless
     Kerr-McGee has furnished you a copy for your review prior to filing and
     will not file any such proposed amendment or supplement to which you
     reasonably object.  Subject to the foregoing sentence, if the Kerr-McGee
     Registration Statement has become or becomes effective pursuant to Rule
     430A, or filing of the Final Kerr-McGee Prospectus is otherwise required
     under Rule 424(b), Kerr-McGee will cause the Final Kerr-McGee Prospectus,
     properly completed, and any supplement thereto to be filed with the
     Commission pursuant to the applicable paragraph of Rule 424(b) within the
     time period prescribed and will provide evidence satisfactory to the
     Representatives of such timely filing.  Kerr-McGee will promptly advise the
     Representatives (1) when the Final Kerr-McGee Prospectus, and any
     supplement thereto, shall have been filed (if required) with the Commission
     pursuant to Rule 424(b), (2) when, prior to termination of the offering of
     the DECS, any amendment to the Kerr-McGee Registration Statement shall have
     been filed or become effective, (3) of any request by the Commission or its
     staff for any amendment of the Kerr-McGee

                                       13


     Registration Statement or for any supplement to the Final Kerr-McGee
     Prospectus or for any additional information, (4) of the issuance by the
     Commission of any stop order suspending the effectiveness of the Kerr-McGee
     Registration Statement or the institution or threatening of any proceeding
     for that purpose and (5) of the receipt by Kerr-McGee of any notification
     with respect to the suspension of the qualification of the DECS for sale in
     any jurisdiction or the institution or threatening of any proceeding for
     such purpose. Kerr-McGee will use its reasonable best efforts to prevent
     the issuance of any such stop order or the suspension of any such
     qualification and, if issued, to obtain as soon as possible the withdrawal
     thereof.

          (b)  If, at any time when a prospectus relating to the DECS is
     required to be delivered under the Act, any event occurs as a result of
     which the Final Kerr-McGee Prospectus as then supplemented would include
     any untrue statement of a material fact or omit to state any material fact
     necessary to make the statements therein in the light of the circumstances
     under which they were made not misleading, or if it shall be necessary to
     amend the Kerr-McGee Registration Statement or supplement the Final
     Kerr-McGee Prospectus to comply with the Act or the Exchange Act or the
     respective rules thereunder, Kerr-McGee promptly will (1) notify the
     Representatives of such event, (2) prepare and file with the Commission,
     subject to the second sentence of paragraph (a) of this Section 6, an
     amendment or supplement which will correct such statement or omission or
     effect such compliance, and (3) supply any supplemented Final Kerr-McGee
     Prospectus to you in such quantities as you may reasonably request.

          (c)  As soon as practicable, Kerr-McGee will make generally available
     to its security holders and to the Representatives an earnings statement or
     statements of Kerr-McGee and its subsidiaries which will satisfy the
     provisions of Section 11(a) of the Act and Rule 158 under the Act.

          (d)  Kerr-McGee will furnish to the Representatives and counsel for
     the Underwriters, without charge, signed copies of the Kerr-McGee
     Registration Statement (including exhibits thereto) and to each other
     Underwriter a copy of the Kerr-McGee Registration Statement (without
     exhibits thereto) and, so long as delivery of a prospectus by an
     Underwriter or dealer may be required by the Act, as many copies of each
     Preliminary Final Kerr-McGee Prospectus and the Final Kerr-McGee Prospectus
     and any supplement thereto as the Representatives may reasonably request.
     Kerr-McGee will pay the expenses of printing or other production of all
     documents relating to the offering.

          (e)  Kerr-McGee will arrange, if necessary, for the qualification of
     the DECS and the Shares for sale under the laws of such jurisdictions as
     the Representatives may designate, will maintain such qualifications in
     effect so long as required for the distribution of the DECS and the Shares
     and will pay any fee of the National Association of Securities Dealers,
     Inc., in connection with its review of the offering; provided that in no
     event shall Kerr-McGee be obligated to qualify to do business in any
     jurisdiction where it is not now so qualified or to take any action that
     would subject it to service of process in suits, other than those arising
     out of the offering or sale of the DECS or Shares in any jurisdiction where
     it is not now so subject.

                                       14


          (f)  Kerr-McGee will not, without the prior written consent of Salomon
     Smith Barney Inc., offer, sell, contract to sell, or otherwise dispose of
     (or enter into any transaction which is designed to, or might reasonably be
     expected to, result in the disposition (whether by actual disposition or
     effective economic disposition due to cash settlement or otherwise) by
     Kerr-McGee or any affiliate of Kerr-McGee or any person in privity with
     Kerr-McGee or any affiliate of Kerr-McGee) directly or indirectly,
     including the filing (or participation in the filing) of a registration
     statement with the Commission in respect of, any debt securities issued or
     guaranteed by Kerr-McGee or publicly announce an intention to effect any
     such transaction (other than in connection with the DECS), for a period of
     7 days after the date of the Underwriting Agreement.

          (g) Kerr-McGee will not take, directly or indirectly, any action
     designed to or which has constituted or which might reasonably be expected
     to cause or result, under the Exchange Act or otherwise, in stabilization
     or manipulation of the price of any security of Kerr-McGee to facilitate
     the sale or resale of the DECS or the Shares.

          7.  Agreements of Devon Energy.

          Devon Energy agrees with the several Underwriters and Kerr-McGee that:

          (a)  Devon Energy will use its best efforts to cause the Devon Energy
     Registration Statement, if not effective at the Execution Time, and any
     amendment thereof, to become effective.  Prior to the termination of the
     offering of the DECS, Devon Energy will not file any amendment of the Devon
     Energy Registration Statement or supplement to the Devon Energy Prospectus
     unless Devon Energy has furnished you and Kerr-McGee a copy for your review
     and Kerr-McGee's information prior to filing and will not file any such
     proposed amendment or supplement to which you or Kerr-McGee reasonably
     objects.  Subject to the foregoing sentence, if the Devon Energy
     Registration Statement has become or becomes effective pursuant to Rule
     430A, or filing of the Devon Energy Prospectus is otherwise required under
     Rule 424(b), Devon Energy will cause the Devon Energy Prospectus, properly
     completed, and any supplement thereto to be filed with the Commission
     pursuant to the applicable paragraph of Rule 424(b) within the time period
     prescribed and will provide evidence satisfactory to the Representatives
     and Kerr-McGee of such timely filing.  Devon Energy will promptly advise
     the Representatives and Kerr-McGee (1) when the Devon Energy Registration
     Statement, if not effective at the Execution Time, and any amendment
     thereto, shall have become effective, (2) when the Devon Energy Prospectus,
     and any supplement thereto, shall have been filed (if required) with the
     Commission pursuant to Rule 424(b), (3) when, prior to termination of the
     offering of the Shares, any amendment to the Devon Energy Registration
     Statement shall have been filed or become effective, (4) if any request by
     the Commission or its staff for any amendment of the Devon Energy
     Registration Statement or supplement to the Devon Energy Prospectus or for
     any additional information, (5) of the issuance by the Commission of any
     stop order suspending the effectiveness of the Devon Energy Registration
     Statement or the institution or threatening of any proceeding for that
     purpose and (6) of the receipt by Devon Energy of any notification with
     respect to the suspension of the qualification of the Shares for sale in
     any jurisdiction or the institution or threatening of any proceeding for
     such purpose.  Devon Energy will use its best efforts to

                                       15


     prevent the issuance of any such stop order or the suspension of any such
     qualification and, if issued, to obtain as soon as possible the withdrawal
     thereof.

          (b)  If, at any time when a prospectus relating to the Devon Energy
     Common Stock is required to be delivered under the Act, any event occurs as
     a result of which the Devon Energy Prospectus as then supplemented would
     include any untrue statement of a material fact or omit to state any
     material fact necessary to make the statements therein in the light of the
     circumstances under which they were made not misleading, or if it shall be
     necessary to amend the Devon Energy Registration Statement or supplement
     the Devon Energy Prospectus to comply with the Act or the Exchange Act or
     the respective rules thereunder, Devon Energy promptly will (1) notify the
     Representatives and Kerr-McGee of such event, (2) prepare and file with the
     Commission, subject to the second sentence of paragraph (a) of this Section
     7, an amendment or supplement which will correct such statement or omission
     or effect such compliance, and (3) supply only the supplemented Devon
     Energy Prospectus to you in such quantities as you may reasonably request
     and supply one copy of the supplemented Devon Energy Prospectus to Kerr-
     McGee.

          (c)  As soon as practicable, Devon Energy will make generally
     available to its security holders and to the Representatives an earnings
     statement or statements of Devon Energy and its subsidiaries which will
     satisfy the provisions of Section 11(a) of the Act and Rule 158 under the
     Act.

          (d)  Devon Energy will furnish to the Representatives and counsel for
     the Underwriters and Kerr-McGee and its counsel, without charge, signed
     copies of the Devon Energy Registration Statement (including exhibits
     thereto) and to each other Underwriter and Kerr-McGee a copy of the Devon
     Energy Registration Statement (without exhibits thereto) and, so long as
     delivery of a prospectus by an Underwriter or dealer may be required by the
     Act, as many copies of each Preliminary Devon Energy Prospectus and the
     Devon Energy Prospectus and any supplement thereto as the Representatives
     may reasonably request.  Kerr-McGee will pay the expenses of printing or
     other production of all documents relating to the offering.

          (e)  Devon Energy will, if necessary, cooperate with Kerr-McGee for
     purposes of the qualification of the DECS for sale under the laws of such
     jurisdictions as the Representatives may designate and maintenance of such
     qualifications in effect so long as required for the distribution of the
     DECS and the Shares; Devon Energy will arrange for the qualification of the
     Shares for sale under the laws of such jurisdictions as the Representatives
     may designate and will maintain such qualifications in effect so long as
     required for the distribution of the DECS and the Shares; provided, that in
     no event shall Devon Energy be obligated to qualify to do business in any
     jurisdiction where it is not now so qualified or to take any action that
     would subject it to service of process in suits, other than those arising
     out of the offering or sale of the Shares in any jurisdiction where it is
     not now so subject.

          (f) Devon Energy and Devon Delaware (as defined below) will not,
     without the prior written consent of Salomon Smith Barney Inc. (which shall
     not be unreasonably

                                       16


     withheld), offer, sell, contract to sell, or otherwise dispose of (or enter
     into any transaction which is designed to, or might reasonably be expected
     to, result in the disposition (whether by actual disposition or effective
     economic disposition due to cash settlement or otherwise) by Devon Energy,
     Devon Delaware or any affiliate of either of them or any person in privity
     with either of them or any affiliate of either of them) directly or
     indirectly, including the filing (or participation in the filing) of a
     registration statement with the Commission in respect of, or establish or
     increase a put equivalent position or liquidate or decrease a call
     equivalent position within the meaning of Section 16 of the Exchange Act,
     any shares of common stock or any securities convertible into, or
     exchangeable for, or warrants to acquire shares of common stock (other than
     the Shares in connection with the offering by Kerr-McGee of the DECS) or
     publicly announce an intention to effect any such transaction, on or prior
     to the Lockup Termination Date (as defined below); provided, however, that:

               (i) Devon Energy or Devon Delaware may publicly announce and
          discuss its intention to offer and sell, for up to $500 million,
          shares of its capital stock or securities convertible into, or
          exchangeable for, or warrants to acquire shares of such capital stock
          (any such offering, a "Devon Offering"); and

               (ii) Devon Energy or Devon Delaware may file a registration
          statement with the Commission relating to a Devon Offering and may
          offer the shares to be registered thereby;

     provided further, that, for the avoidance of doubt:

               (A) Devon Delaware Corporation, a Delaware corporation ("Devon
          Delaware"), which is to be renamed Devon Energy Corporation following
          the proposed merger of PennzEnergy with Devon Delaware, may issue
          shares of its common stock to (1) shareholders of PennzEnergy Company
          ("PennzEnergy") in the proposed merger of PennzEnergy with Devon
          Delaware and (2) shareholders of Devon Energy in the proposed merger
          of Devon Oklahoma Corporation, an Oklahoma corporation ("Devon
          Oklahoma"), with Devon Energy (each such merger as described in Devon
          Energy's proxy statement dated __________, 1999);

               (B) Devon Energy or any of its affiliates may offer to issue and
          issue shares of its capital stock, or any securities convertible into,
          or exchangeable for, or warrants to acquire shares of such capital
          stock, in any such case, to any owner of any business or assets
          acquired or proposed to be acquired by Devon Energy or any of its
          affiliates, as consideration for any such acquisition or proposed
          acquisition, and in connection therewith publicly announce any such
          issuance or contemplated issuance or file with the Commission any
          related registration statement; provided, however, that securities
          issuances for other than cash consideration as contemplated by this
          paragraph shall not exceed $250 million and, together with any
          securities issuances for cash as contemplated above, shall not exceed
          $500 million of aggregate securities issuances prior to the Lockup
          Termination Date;

                                       17


               (C) Devon Energy or Devon Delaware may issue shares of its common
          stock in connection with any exchange, redemption or retraction of
          Northstar Energy Corporation exchangeable shares; and

               (D) Devon Energy, Devon Delaware, PennzEnergy or any of their
          respective affiliates may issue shares of capital stock pursuant to
          (x) any stock option plan, equity incentive plan, stock purchase plan
          or dividend reinvestment plan existing as of July 14, 1999 or as
          contemplated by the Amended and Restated Agreement and Plan of Merger,
          dated May 19, 1999, by and among Devon Energy, Devon Delaware, Devon
          Oklahoma and PennzEnergy and the related Registration Statement on
          Form S-4 of Devon Energy, or (y) any security convertible into or
          exercisable or exchangeable for any such capital stock outstanding as
          of July 14, 1999.

     The "Lockup Termination Date" shall be the earlier of (I) the 45th day
     after the date of this Agreement or (II) if the Devon Energy Registration
     Statement is declared effective by the Commission on or prior to August 2,
     1999, September 6, 1999 or (III) if, at Kerr-McGee's request (assuming
     that, in Devon Energy's reasonable judgment, a Devon Energy Registration
     Statement is available for filing and would comply with the rules under the
     Act), Devon Energy does not (x) file the Devon Energy Registration
     Statement with the Commission on or prior to July 16, 1999 or (y) on or
     prior to July 22, 1999, request the Commission to declare the Devon Energy
     Registration Statement effective, September 6, 1999.

          (g) Devon Energy will not take, directly or indirectly, any action
     designed to or which has constituted or which might reasonably be expected
     to cause or result, under the Exchange Act or otherwise, in stabilization
     or manipulation of the price of any security of Devon Energy to facilitate
     the sale or resale of the DECS or the Shares.

          (h)  Devon Energy will furnish the Trustee, in sufficient quantities
     for transmission to holders of the DECS, Devon Energy's annual report to
     shareholders and reports on Forms 10-K and 10-Q as soon as practicable
     after such reports are required to be filed with the Commission.

          (i)  Devon Energy will take such actions as may be reasonably
     necessary to comply with the rules and regulations of the AMEX in respect
     of the offering of the Shares contemplated hereby.

          (j)  Devon Energy will use its reasonable best efforts to furnish to
     Kerr-McGee the opinion of McAfee & Taft, A Professional Corporation,
     counsel for Devon Energy, dated as of the Closing Date, substantially
     similar to the opinion to be provided pursuant to Section 8(e) hereof, and
     the officers' certificate, dated as of the Closing Date, substantially
     similar to the certificate to be provided pursuant to Section 8(g) hereof.

          (k)  Devon Energy will use its reasonable best efforts to have the
     letters of KPMG LLP and Arthur Andersen LLP, dated as of the Execution Time
     and as of the Closing

                                       18


     Date, to be provided pursuant to Section 8(i) and Section 8(j) hereof,
     respectively, addressed to Kerr-McGee in addition to the Representatives.

          8.  Conditions to the Obligations of the Underwriters.  The
obligations of the Underwriters to purchase the DECS shall be subject to the
accuracy of the representations and warranties on the part of Kerr-McGee and
Devon Energy contained herein as of the Execution Time, the Closing Date and any
settlement date pursuant to Section 4 hereof, to the accuracy of the statements
of Kerr-McGee and Devon Energy made in any certificates pursuant to the
provisions hereof, to the performance by Kerr-McGee and Devon Energy of their
respective obligations hereunder and to the following additional conditions:

          (a)  If the Devon Energy Registration Statement has not become
effective prior to the Execution Time, unless the Representatives agree in
writing to a later time, the Devon Energy Registration Statement will become
effective not later than (i) 6:00 PM, New York City time, on the date of
determination of the public offering price, if such determination occurred at or
prior to 3:00 PM New York City time, on such date or (ii) 9:30 AM, New York City

such Final Kerr-McGee Prospectus or Devon Energy Prospectus, and any such

Rule 424(b); and no stop order suspending the effectiveness of the Kerr-McGee
Registration Statement or the Devon Energy Registration Statement shall have
been issued and no proceedings for that purpose shall have been instituted or
threatened.

          (b)  (i)  Kerr-McGee shall have furnished to the Representatives an
opinion of ____________, corporate counsel for Kerr-McGee, dated as of the
Closing Date and addressed to the Representatives, to the effect that:

          (A) each of Kerr-McGee and each of its Kerr-McGee Significant
     Subsidiaries has been duly incorporated and is validly existing as a
     corporation in good standing under the laws of the jurisdiction in which it
     is organized, with full corporate power and authority to own its properties
     and conduct its business as described in the Final Kerr-McGee Prospectus,
     and is duly qualified to do business as a foreign corporation and is in
     good standing under the laws of each jurisdiction in which the failure so
     to qualify would have a material adverse effect on the [financial
     condition, results of operations, prospects, earnings or properties] of
     Kerr-McGee and its subsidiaries, taken as a whole;

          (B) all the outstanding shares of capital stock of each of the Kerr-
     McGee Significant Subsidiaries, except for director's qualifying shares and
     as otherwise set forth in the Kerr-McGee Registration Statement, are owned
     by Kerr-McGee either directly or through wholly owned subsidiaries free and
     clear of any perfected security interest and, to the knowledge of such
     counsel, after due inquiry, any other security interest, claim, lien or
     encumbrance;

          (C) Kerr-McGee's authorized equity capitalization is as set forth in
     the Final Kerr-McGee Prospectus; the DECS are duly listed, and admitted and
     authorized for

                                       19


     trading subject to official notice of issuance, on the AMEX, and, except as
     set forth in the Final Kerr-McGee Prospectus, no options, warrants or other
     rights to purchase, agreements or other obligations to issue, or rights to
     convert any obligations into or exchange any securities for, shares of
     capital stock of or ownership interests in Kerr-McGee are outstanding;

          (D) to the knowledge of such counsel, there is no pending or
     threatened action, suit or proceeding by or before any court or
     governmental agency, authority or body or any arbitrator involving Kerr-
     McGee or any of its subsidiaries or its or their property, of a character
     required to be disclosed in the Kerr-McGee Registration Statement which is
     not adequately disclosed in the Final Kerr-McGee Prospectus, and there is
     no franchise, contract or other document of a character required to be
     described in the Kerr-McGee Registration Statement or Final Kerr-McGee
     Prospectus, or to be filed as an exhibit thereto, which is not described or
     filed as required;

          (E) to the best knowledge of such counsel, Kerr-McGee is the record
     and beneficial owner of the Shares free and clear of all liens,
     encumbrances, equities and claims;

          (F) neither the execution and delivery of the Indenture, the issue and
     sale of the DECS and the Shares, nor the consummation of any other of the
     transactions herein contemplated nor the fulfillment of the terms hereof
     will conflict with, result in a breach or violation of or imposition of any
     lien, charge or encumbrance upon any property or assets of Kerr-McGee or
     any Kerr-McGee Significant Subsidiary pursuant to, (i) the charter or by-
     laws of Kerr-McGee or any Kerr-McGee Significant Subsidiary, (ii) the terms
     of any material indenture, contract, lease, mortgage, deed of trust, note
     agreement, loan agreement or other agreement, obligation, condition,
     covenant or instrument to which Kerr-McGee or any Kerr-McGee Significant
     Subsidiary is a party or bound or to which its or their property is
     subject, or (iii) any statute, law, rule, regulation, judgment, order or
     decree applicable to Kerr-McGee or any Kerr-McGee Significant Subsidiary of
     any court, regulatory body, administrative agency, governmental body,
     arbitrator or other authority having jurisdiction over Kerr-McGee or its
     subsidiaries or any of its or their properties; and

          (G) no holders of securities of Kerr-McGee have rights to the
     registration of such securities under the Kerr-McGee Registration
     Statement.

          (ii) Kerr-McGee shall have requested and caused Simpson Thacher &
Bartlett, counsel for Kerr-McGee, to have furnished to the Representatives their
opinion dated as of the Closing Date and addressed to the Representatives, to
the effect that:

          (A) the statements made in the Basic Kerr-McGee Prospectus under the
     caption "Description of Debt Securities" and in the Final Kerr-McGee
     Prospectus Supplement under the caption "Description of DECS," insofar as
     they purport to constitute summaries of certain terms of documents referred
     to therein, constitute accurate summaries of the terms of such documents in
     all material respects; the statements set forth under the heading "Certain
     United States Federal Income Tax

                                       20


     Consequences" in the Final Kerr-McGee Prospectus, insofar as such
     statements purport to summarize certain federal income tax laws of the
     United States, constitute a fair summary of the principal U.S. federal
     income tax consequences of the purchase of DECS by an initial U.S. Holder
     (as defined in the Final Kerr-McGee Prospectus);

          (B) no consent, approval, authorization, order, registration or
     qualification of or with any Federal or New York governmental agency or
     body or any Delaware governmental agency or body acting pursuant to the
     Delaware General Corporation Law or, to our knowledge, any Federal or New
     York court or any Delaware court acting pursuant to the Delaware General
     Corporation Law is required for the issue and sale of the DECS by Kerr-
     McGee and the compliance by Kerr-McGee with all of the provisions of the
     Underwriting Agreement, except for the registration under the Act of the
     DECS, and such consents, approvals, authorizations, registrations or
     qualifications as may be required under state securities or Blue Sky laws
     in connection with the purchase and distribution of the DECS by the
     Underwriters;

          (C) the Indenture has been duly authorized, executed and delivered by
     Kerr-McGee and duly qualified under the Trust Indenture Act and, assuming
     due authorization, execution and delivery thereof by the Trustee,
     constitutes a valid and legally binding obligation of Kerr-McGee
     enforceable against Kerr-McGee in accordance with its terms;

          (D) the DECS have been duly authorized, executed and issued by Kerr-
     McGee and, assuming due authentication thereof by the Trustee and upon
     payment and delivery and in accordance with the Underwriting Agreement,
     will constitute valid and legally binding obligations of Kerr-McGee
     enforceable against Kerr-McGee in accordance with their terms and entitled
     to the benefits of the Indenture;

          (E) the Kerr-McGee Registration Statement has become effective under
     the Act and the Basic Kerr-McGee Prospectus, the Preliminary Final Kerr-
     McGee Prospectus and the Final Kerr-McGee Prospectus Supplement were each
     filed pursuant to Rule 424(b) of the rules and regulations of the
     Commission under the Act and, to our knowledge, no stop order suspending
     the effectiveness of the Kerr-McGee Registration Statement has been issued
     or proceeding for that purpose has been instituted or threatened by the
     Commission;

          (F) the Underwriting Agreement has been duly authorized, executed and
     delivered by Kerr-McGee;

          (G) Kerr-McGee is not and, after giving effect to the offering and
     sale of the DECS and the application of the proceeds thereof as described
     in the Final Kerr-McGee Prospectus, will not be an "investment company"
     within the meaning of and subject to regulation under the Investment
     Company Act of 1940, as amended; and

          (H) such counsel has not independently verified the accuracy,
     completeness or fairness of the statements made or included in the Kerr-
     McGee Registration Statement and the Final Kerr-McGee Prospectus or the
     documents incorporated by reference therein

                                       21


     and takes no responsibility therefor, except as and to the extent set forth
     in paragraph (A) above. Such counsel shall also state that in the course of
     the preparation by Kerr-McGee of the Kerr-McGee Registration Statement and
     the Final Kerr-McGee Prospectus, excluding the documents incorporated
     therein by reference, such counsel participated in conferences with certain
     officers and employees of Kerr-McGee, with representatives of Arthur
     Andersen and counsel to Kerr-McGee. Such opinion shall also state that such
     counsel did not participate in the preparation of documents incorporated by
     reference in the Final Kerr-McGee Prospectus. Based upon such counsel's
     examination of the Kerr-McGee Registration Statement and the Final
     Kerr-McGee Prospectus and the documents incorporated by reference therein,
     and such counsel's investigations made in connection with the preparation
     of the Kerr-McGee Registration Statement and the Final Kerr-McGee
     Prospectus, including any documents incorporated by reference therein and
     such counsel's participation in conferences referred to above, (i) such
     counsel is of the opinion that the Kerr-McGee Registration Statement, as of
     its effective date, and the Final Kerr-McGee Prospectus, as of its date,
     complied as to form in all material respects with requirements of the Act,
     the Trust Indenture Act and the applicable rules and regulations of the
     Commission thereunder and that the documents incorporated by reference in
     the Final Kerr-McGee Prospectus complied as to form when filed in all
     material respects with the requirements of the Exchange Act and the
     applicable rules and regulations of the Commission thereunder, except that,
     in each case, such counsel need not express an opinion with respect to the
     financial statements or other financial data contained or incorporated by
     reference in the Kerr-McGee Registration Statement, the Final Kerr-McGee
     Prospectus or the documents incorporated by reference in the Final
     Kerr-McGee Prospectus, and (ii) such counsel has no reason to believe that
     the Kerr-McGee Registration Statement, as of its effective date, contained
     any untrue statement of a material fact or omitted to state any material
     fact required to be stated therein or necessary in order to make the
     statements therein not misleading or that the Final Kerr-McGee Prospectus
     (including the documents incorporated by reference therein) contains any
     untrue statement of a material fact or omits to state any material fact
     necessary in order to make the statements therein, in the light of the
     circumstances under which they were made, not misleading, except that in
     each case, such counsel need not express a belief with respect to the
     financial statements or other financial data contained or incorporated by
     reference in the Kerr-McGee Registration Statement, the Final Kerr-McGee
     Prospectus or the documents incorporated by reference into the Final
     Kerr-McGee Prospectus.

     In rendering such opinion, such counsel may rely (A) as to matters
involving the application of laws of any jurisdiction other than the States of
New York and Delaware or the United States, to the extent such counsel deems
proper and specified in such opinion, upon the opinion of other counsel of good
standing whom such counsel believes to be reliable and who are satisfactory to
counsel for the Underwriters and (B) as to matters of fact, to the extent such
counsel deems proper, on certificates of responsible officers of Kerr-McGee and
public officials.   References to the Final Kerr-McGee Prospectus in this
paragraph (b) include any supplements thereto at the Closing Date.

          (c)  The Representatives shall have received from Cleary, Gottlieb,
Steen & Hamilton, counsel for the Underwriters, such opinion or opinions, dated
the Closing Date, with

                                       22


respect to the issuance and sale of the DECS, the Indenture, the Kerr-McGee
Registration Statement, the Final Kerr-McGee Prospectus (together with any
supplement thereto), the Shares, the Devon Energy Registration Statement, the
Devon Energy Prospectus (together with any supplement thereto) and other related
matters as the Representatives may reasonably require, and Kerr-McGee and Devon
Energy shall have furnished to such counsel such documents as they request for
the purpose of enabling them to pass upon such matters.

          (d)  Devon Energy shall have furnished to the Representatives the
opinion of McAfee & Taft, a Professional Corporation, counsel for Devon Energy,
dated as of the Closing Date, to the effect that:

          (i)  each of Devon Energy and each of its subsidiaries has been duly
     incorporated and is validly existing as a corporation in good standing
     under the laws of the jurisdiction in which it is chartered or organized,
     with full corporate power and authority to own its properties and conduct
     its business as described in the Devon Energy Prospectus, and is duly
     qualified to do business as a foreign corporation and is in good standing
     under the laws of each jurisdiction which requires such qualification
     wherein it owns or leases material properties or conducts material business
     as listed in the Devon Energy Prospectus, except where the failure to
     qualify would not have a material adverse effect on the [financial
     condition, results of operations, prospects, earnings or properties] of
     Devon Energy and its consolidated subsidiaries, taken as a whole;

          (ii)  all the outstanding shares of capital stock of each subsidiary
     have been duly and validly authorized and issued and are fully paid and
     nonassessable, and, except as otherwise set forth in the Devon Energy
     Prospectus, all outstanding shares of capital stock of the subsidiaries are
     owned by Devon Energy either directly or through wholly owned subsidiaries
     free and clear of any perfected security interest and, to the knowledge of
     such counsel, after due inquiry, any other security interests, claims,
     liens or encumbrances;

          (iii)  Devon Energy's authorized equity capitalization is as set forth
     in the Devon Energy Prospectus; the Shares are duly listed and admitted for
     trading on the AMEX; the Devon Energy Common Stock conforms in all material
     respects to the description thereof contained in the Devon Energy
     Prospectus; the outstanding shares of Devon Energy Common Stock (including
     the Shares) have been duly and validly authorized and issued and are fully
     paid and non-assessable; the certificates for the Shares are in valid and
     sufficient form;

          (iv)  to the best knowledge of such counsel, there is no pending or
     threatened action, suit or proceeding before any court or governmental
     agency, authority or body or any arbitrator involving Devon Energy or any
     of its subsidiaries of a character required to be disclosed in the Devon
     Energy Registration Statement which is not adequately disclosed in the
     Devon Energy Prospectus, and there is no franchise, contract or other
     document of a character required to be described in the Devon Energy
     Registration Statement or Devon Energy Prospectus, or to be filed as an
     exhibit, which is not described or filed as required; and the statements in
     the Devon Energy Prospectus under

                                       23


     the headings "Description of Capital Stock" fairly summarize the matters
     therein described;

          (v)  the Devon Energy Registration Statement has become effective
     under the Act; any required filing of the Devon Energy Prospectus, and of
     any supplements thereto, pursuant to Rule 424(b) has been made in the
     manner and within the time period required by Rule 424(b); to the best
     knowledge of such counsel, no stop order suspending the effectiveness of
     the Devon Energy Registration Statement has been issued, no proceedings for
     that purpose have been instituted or threatened;

          (vi)  this Agreement has been duly authorized, executed and delivered
     by Devon Energy;

          (vii)  no consent, approval, authorization or order of any court or
     governmental agency or body is required for the consummation by Devon
     Energy of the transactions contemplated herein, except such as have been
     obtained under the Act and such as may be required under the blue sky laws
     of any jurisdiction in connection with the purchase and distribution of the
     DECS by the Underwriters and the distribution of the Shares pursuant to the
     terms of the DECS and such other approvals (specified in such opinion) as
     have been obtained;

          (viii)  neither the distribution of the Shares, nor the consummation
     of any other of the transactions herein contemplated nor the fulfillment of
     the terms hereof will conflict with, result in a breach or violation of, or
     constitute a default under any law or the charter or by-laws of Devon
     Energy or the terms of any indenture or other agreement or instrument known
     to such counsel and to which Devon Energy or any of its subsidiaries is a
     party or bound or any judgment, order or decree known to such counsel to be
     applicable to Devon Energy or any of its subsidiaries of any court,
     regulatory body, administrative agency, governmental body or arbitrator
     having jurisdiction over Devon Energy or any of its subsidiaries; and

          (ix)  No holders of securities of Devon Energy, other than Kerr-McGee,
     have rights to the registration of Devon Energy Common Stock under the
     Devon Energy Registration Statement.

     In addition such counsel shall state that, although such counsel makes no
representation as to the accuracy or completeness of the statements of fact
contained in the Devon Energy Registration Statement and the Devon Energy
Prospectus, no facts have come to such counsel's attention which lead such
counsel to believe that, at the Devon Energy Effective Date, the Devon Energy
Registration Statement and the Devon Energy Prospectus (other than the financial
statements and other financial or accounting information contained therein or
omitted therefrom as to which such counsel need express no opinion) did not
comply as to form in all material respects with the applicable requirements of
the Act and the Exchange Act and the respective rules thereunder; and such
counsel has no reason to believe that at the Devon Energy Effective Date the
Devon Energy Registration Statement (other than the financial statements and
other financial or accounting information included therein or omitted therefrom
as to which such counsel need express no opinion) contained any untrue statement
of a material fact or omitted to

                                       24


state any material fact required to be stated therein or necessary to make the
statements therein not misleading or that the Devon Energy Prospectus (other
than the financial statements and other financial or accounting information
included therein or omitted therefrom as to which such counsel need express no
opinion) includes any untrue statement of a material fact or omits to state a
material fact necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading.

     In rendering such opinion, such counsel may rely (A) as to matters
involving the application of laws of any jurisdiction other than the State of
Oklahoma or the United States, to the extent such counsel deems proper and
specified in such opinion, upon the opinion of other counsel of good standing
whom such counsel believes to be reliable and who are satisfactory to counsel
for the Underwriters and (B) as to matters of fact, to the extent such counsel
deems proper, on certificates of responsible officers of Devon Energy and public
officials.   References to the Devon Energy Prospectus in this paragraph (d)
include any supplements thereto at the Closing Date.

          (e)  Kerr-McGee shall have furnished to the Representatives a

any supplements to the Final Kerr-McGee Prospectus and this Agreement and that:

          (i)  the representations and warranties of Kerr-McGee in this
     Agreement are true and correct in all material respects on and as of the
     Closing Date with the same effect as if made on the Closing Date and Kerr-
     McGee has complied with all the agreements and satisfied all the conditions
     on its part to be performed or satisfied at or prior to the Closing Date;

          (ii)  no stop order suspending the effectiveness of the Kerr-McGee
     Registration Statement has been issued and no proceedings for that purpose
     have been instituted or, to Kerr-McGee's knowledge, threatened; and

          (iii)  since the date of the most recent financial statements included
     or incorporated by reference in the Final Kerr-McGee Prospectus (exclusive
     of any supplement thereto), there has been no material adverse effect on
     the condition (financial or otherwise), prospects, earnings, business or
     properties of Kerr-McGee and its subsidiaries taken as a whole, whether or
     not arising from transactions in the ordinary course of business, except as
     set forth in or contemplated in the Final Kerr-McGee Prospectus (exclusive

and that:

                                       25


          (i) the representations and warranties of Devon Energy in this
     Agreement are true and correct in all material respects on and as of the
     Closing Date with the same effect as if made on the Closing Date and Devon
     Energy has complied with all the agreements and satisfied all the
     conditions on its part to be performed or satisfied at or prior to the
     Closing Date;

          (ii) no stop order suspending the effectiveness of the Devon Energy
     Registration Statement has been issued and no proceedings for that purpose
     have been instituted or, to Devon Energy's knowledge, threatened; and

          (iii) since the date of the most recent financial statements included
     or incorporated by reference in the Devon Energy Prospectus (exclusive of

     or not arising from transactions in the ordinary course of business, except
     as set forth in or contemplated in the Devon Energy Prospectus (exclusive
     of any supplement thereto).

          (g)  Kerr-McGee shall have requested and caused Arthur Andersen LLP to
have furnished to the Representatives at the Execution Time and at the Closing

they are independent accountants within the meaning of the Act and the Exchange
Act and the respective applicable rules and regulations adopted by the
Commission thereunder and that they have performed a review of the unaudited
interim financial information of Kerr-McGee for the three-month period ended
March 31, 1999, and as at March 31, 1999, in accordance with Statement on
Auditing Standards No. 71, and stating in effect that:

          (i)  in their opinion the audited financial statements and financial
     statement schedules included or incorporated in the Kerr-McGee Registration
     Statement and the Final Kerr-McGee Prospectus and reported on by them
     comply in form in all material respects with the applicable accounting
     requirements of the Act and the Exchange Act and the related rules and

     statements made available by the Kerr-McGee and its subsidiaries; their
     limited review, in accordance with standards established under Statement on
     Auditing Standards No. 71, of the unaudited interim financial information
     for the three-month period ended March 31, 1999, and as at March 31, 1999;
     carrying out certain specified procedures (but not an examination in
     accordance with generally accepted auditing standards) which would not
     necessarily reveal matters of significance with respect to the comments set
     forth in such letter; a reading of the minutes of the meetings of the
     stockholders, directors and [executive, finance, audit] committees of Kerr-
     McGee and its subsidiaries; and inquiries of certain officials of Kerr-
     McGee who have responsibility for financial and accounting matters of Kerr-
     McGee and its subsidiaries as to transactions and events subsequent to
     December 31, 1998, nothing came to their attention which caused them to
     believe that:

                                       26


               (1)  any unaudited financial statements included or incorporated
          by reference in the Kerr-McGee Registration Statement and the Final
          Kerr-McGee Prospectus do not comply as to form in all material
          respects with applicable accounting requirements of the Act and with
          the related rules and regulations adopted by the Commission with
          respect to financial statements included or incorporated by reference
          in quarterly reports on Form 10-Q under the Exchange Act; and said
          unaudited financial statements are not in conformity with generally
          accepted accounting principles applied on a basis substantially
          consistent with that of the audited financial statements included or
          incorporated by reference in the Kerr-McGee Registration Statement and
          the Final Kerr-McGee Prospectus;

               (2)  with respect to the period subsequent to March 31, 1999,
          there were any changes, at a specified date not more than five days
          prior to the date of the letter, in the [long-term debt] of Kerr-McGee
          and its subsidiaries or, capital stock of Kerr-McGee, or decreases in
          the [stockholders' equity] of Kerr-McGee, [other appropriate line
          items] as compared with the amounts shown on the March 31, 1999
          consolidated balance sheet included or incorporated in the Kerr-McGee
          Registration Statement and the Final Kerr-McGee Prospectus, or for the
          period from April 1, 1999 to such specified date there were any
          decreases, as compared with the corresponding period in the preceding
          year in [consolidated revenues, net income or net income per share] of
          Kerr-McGee and its subsidiaries, except in all instances for changes
          or decreases set forth in such letter, in which case the letter shall
          be accompanied by an explanation by Kerr-McGee as to the significance
          thereof unless said explanation is not deemed necessary by the
          Representatives;

               (3) the information included or incorporation by reference in the
          Kerr-McGee Registration Statement and the Final Kerr-McGee Prospectus
          in response to Regulation S-K, Item 301 (Selected Financial Data),
          Item 302 (Supplementary Financial Information), Item 402 (Executive
          Compensation) and Item 503(d) (Ratio of Earnings to Fixed Charges) is
          not in conformity with the applicable disclosure requirements of
          Regulation S-K.

          (iii)  they have performed certain other specified procedures as a
result of which they determined that certain information of an accounting,
financial or statistical nature (which is limited to accounting, financial or
statistical information derived from the general accounting records of
Kerr-McGee and its subsidiaries) set forth in the Kerr-McGee Registration
Statement and the Final Kerr-McGee Prospectus and in Exhibit 12 to the
Kerr-McGee Registration Statement, including the information set forth under the
captions "[      ]" and "[        ]"in the Final Kerr-McGee Prospectus, the

Registration Statement and the Final Kerr-McGee Prospectus, agrees with the
accounting records of Kerr-McGee and its subsidiaries, excluding any questions
of legal interpretation.

supplement thereto at the date of the letter.

          and the Devon Energy Prospectus; or

               (2)  with respect to the period subsequent to March 31, 1999,
          there were any changes, at a specified date not more than five days
          prior to the date of the letter, in the long-term debt of Devon Energy

          corresponding period in the preceding year in consolidated total
          revenues, net income or in the total or per-share amounts of net
          income, except in all instances for changes or decreases set forth in
          such letter, in which case the letter shall be accompanied by an
          explanation by Devon Energy as to the significance thereof unless said
          explanation is not deemed necessary by the Representatives.

          (j)  Subsequent to the Execution Time or, if earlier, the dates as of
which information is given in each of the Kerr-McGee Registration Statement and
the Devon Energy Registration Statement (exclusive of any amendment thereof) and
each of the Final Kerr-McGee

                                       30


Prospectus and the Devon Energy Prospectus (exclusive of any supplement
thereto), there shall not have been (i) any change or decrease specified in the
letter or letters referred to in paragraphs (g), (h) and (i) of this Section 8
or (ii) any change, or any development involving a prospective change, in or
affecting the condition (financial or otherwise), earnings, business or
properties of either Kerr-McGee or Devon Energy and their respective
subsidiaries, taken as a whole, whether or not arising from transactions in the
ordinary course of business, except as set forth in or contemplated in each of
the Final Kerr-McGee Prospectus and the Devon Energy Prospectus (exclusive of
any supplement thereto) the effect of which, in any case referred to in clause
(i) or (ii) above, is, in the sole judgment of the Representatives, so material
and adverse as to make it impractical or inadvisable to proceed with the
offering or delivery of the DECS as contemplated by each of the Kerr-McGee
Registration Statement and the Devon Energy Registration Statement (exclusive of
any amendment thereof) and each of the Final Kerr-McGee Prospectus and the Devon
Energy Prospectus (exclusive of any supplement thereto).

          (k)  Subsequent to the Execution Time, there shall not have been any
decrease in the rating of any of Kerr-McGee's or Devon Energy's debt securities
by any "nationally recognized statistical rating organization" (as defined for
purposes of Rule 436(g) under the Act) or any notice given of any intended or
potential decrease in any such rating or of a possible change in any such rating
that does not indicate the direction of the possible change.

          (l)  Prior to the Closing Date, each of Kerr-McGee and Devon Energy
shall have furnished to the Representatives such further information,
certificates and documents as the Representatives may reasonably request.

          If any of the conditions specified in this Section 8 shall not have
been fulfilled in all material respects when and as provided in this Agreement,
or if any of the opinions and certificates mentioned above or elsewhere in this
Agreement shall not be in all material respects reasonably satisfactory in form
and substance to the Representatives and counsel for the Underwriters, this
Agreement and all obligations of the Underwriters hereunder may be canceled at,
or at any time prior to, the Closing Date by the Representatives.  Notice of
such cancellation shall be given to Kerr-McGee and Devon Energy in writing or by
telephone or facsimile confirmed in writing.

          9.  Reimbursement of Underwriters' Expenses.  If the sale of the DECS
provided for herein is not consummated because any condition to the obligations
of the Underwriters set forth in Section 8 hereof is not satisfied, because of
any termination pursuant to Section 12 hereof or because of any refusal,
inability or failure on the part of Kerr-McGee or Devon Energy to perform any
agreement herein or comply with any provision hereof other than by reason of a
default by any of the Underwriters, Kerr-McGee will reimburse the Underwriters
severally upon demand for all reasonable out-of-pocket expenses (including
reasonable fees and disbursements of counsel) that shall have been incurred by
them in connection with the proposed purchase and sale of the DECS.  The
Underwriters agree to pay such expenses, fees and disbursements in any other
event.  In no event will Kerr-McGee be liable to any of the Underwriters for
damages on account of loss of anticipated profits.

          10.  Indemnification and Contribution.  (a)  Kerr-McGee agrees to
indemnify and hold harmless each Underwriter, the directors, officers, employees
and agents of each

                                       31


Underwriter, and each person who controls any Underwriter within the meaning of
either the Act or the Exchange Act against any and all losses, claims, damages
or liabilities, joint or several, to which they or any of them may become
subject under the Act, the Exchange Act or other Federal or state statutory law
or regulation, at common law or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon any untrue statement or alleged untrue statement of a material fact
contained in the Kerr-McGee Registration Statement as originally filed or in any
amendment thereof, or in the Basic Kerr-McGee Prospectus, any Preliminary Final
Kerr-McGee Prospectus or the Final Kerr-McGee Prospectus (including any
information contained in or omitted from any Preliminary Devon Energy Prospectus
or Devon Energy Prospectus in reliance on and in conformity with information
furnished to Devon Energy by Kerr-McGee), or in any amendment thereof or
supplement thereto, or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and agrees to reimburse
each such indemnified party, as incurred, for any legal or other expenses
reasonably incurred by them in connection with investigating or defending any
such loss, claim, damage, liability or action; provided, however, that Kerr-
McGee will not be liable under the indemnity agreement in this paragraph (a) to
the extent that any such loss, claim, damage or liability arises out of or is
based upon any such untrue statement or alleged untrue statement or omission or
alleged omission made therein in reliance upon and in conformity with written
information furnished to Kerr-McGee by or on behalf of any Underwriter through
the Representatives specifically for inclusion therein or in reliance and in
conformity with the Statement of Eligibility of the Trustee; provided, further,
that Kerr-McGee will not be liable under the indemnity agreement in this
paragraph (a) to the extent that any such loss, claim, damage or liability
arises out of or is based upon any such untrue statement or alleged untrue
statement or omission or alleged omission made in reliance upon and in
conformity with written information furnished to Kerr-McGee by Devon Energy
specifically for inclusion therein (including the information contained in any
Preliminary Devon Energy Prospectus or Devon Energy Prospectus included in any
such document (other than information contained in or omitted from any such
Preliminary Devon Energy Prospectus or Devon Energy Prospectus in reliance on
and conformity with information furnished to Devon Energy by Kerr-McGee
specifically for inclusion therein)); and provided, further that Kerr-McGee
shall not be liable to any Underwriter under the indemnity agreement in this
paragraph (a) with respect to the Preliminary Final Kerr-McGee Prospectus to the
extent that any such loss, claim, damage or liability of such Underwriter
results from the fact that such Underwriter sold DECS to a person as to whom it
shall be established that there was not sent or given, at or prior to the
written confirmation of such sale, a copy of the Final Kerr-McGee Prospectus
(excluding documents incorporated by reference), as the case may be, or of the
Final Kerr-McGee Prospectus as then amended or supplemented (excluding documents
incorporated by reference) in any case where such delivery is required by the
Act and where Kerr-McGee has previously furnished copies thereof in sufficient
quantity to such Underwriter and the loss, claim, damage or liability of such
Underwriter results from an untrue statement or omission of a material fact
contained in the Final Preliminary Kerr-McGee Prospectus and corrected in the
Final Kerr-McGee Prospectus (excluding documents incorporated by reference) or
in the Final Kerr-McGee Prospectus as then amended or supplemented (excluding
documents incorporated by reference). This indemnity agreement will be in

                                       32


          (b)  Kerr-McGee agrees to indemnify and hold harmless Devon Energy,
each of its directors, each of its officers who signs the Devon Energy
Registration Statement, and each person who controls Devon Energy within the
meaning of either the Act or the Exchange Act, against any and all losses,
claims, damages or liabilities, joint or several, to which they or any of them
may become subject under the Act, the Exchange Act or other Federal or state
statutory law or regulation, at common law or otherwise, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof) arise out of or
are based upon any untrue statement or alleged untrue statement of a material
fact contained in the Devon Energy Registration Statement as originally filed or
in any amendment thereof, or in the Preliminary Devon Energy Prospectus or the
Devon Energy Prospectus, or in any amendment thereof or supplement thereto, or
arise out of or are based upon the omission or alleged omission to state therein
a material fact required to be stated therein or necessary to make the
statements therein not misleading, but in each case only to the extent that the
untrue statement or alleged untrue statement or omission or alleged omission is
made in reliance upon and in conformity with written information furnished in
writing to Devon Energy by Kerr-McGee specifically for inclusion therein, and
agrees to reimburse each such indemnified party, as incurred, for any legal or
other expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action.  The indemnity
agreement shall be in addition to any liability which Kerr-McGee may otherwise
have.

          (c)  Devon Energy agrees to indemnify and hold harmless each
Underwriter, the directors, officers, employees and agents of each Underwriter,
and each person who controls any Underwriter within the meaning of either the
Act or the Exchange Act and Devon Energy agrees to indemnify and hold harmless

Exchange Act, in either case, against any and all losses, claims, damages or
liabilities, joint or several, to which they or any of them may become subject
under the Act, the Exchange Act or other Federal or state statutory law or
regulation, at common law or otherwise, insofar as such losses, claims, damages
or liabilities (or actions in respect thereof) arise out of or are based upon
any untrue statement or alleged untrue statement of a material fact contained in
(i) the Devon Energy Registration Statement as originally filed or in any
amendment thereof, or in any Preliminary Devon Energy Prospectus or the Devon
Energy Prospectus, or in any amendment thereof or supplement thereto, or (ii)
the Kerr-McGee Registration Statement as originally filed or in any amendment
thereof, or in any Preliminary Final Kerr-McGee Prospectus or the Final Kerr-
McGee Prospectus, or in any amendment thereto or supplement thereto, or arise
out of or are based upon the omission or alleged omission to state in the
documents referred to in clause (i) or (ii) above a material fact required to be
stated in the documents referred to in clause (i) or (ii) above or necessary to
make the statements therein not misleading, but in the case of the documents
referred to clause (ii) only to the extent that the untrue statement or alleged
untrue statement or omission or alleged omission was made in reliance upon and
in conformity with written information furnished in writing to Kerr-McGee by
Devon Energy specifically for inclusion therein (including the information
contained in any Preliminary  Devon Energy Prospectus or Devon Energy Prospectus
included in any such document (other than information contained in or omitted
from any such Preliminary Devon Energy Prospectus or Devon Energy Prospectus in
reliance on and conformity with information furnished to Devon Energy by Kerr-
McGee specifically for inclusion therein)), and agrees to reimburse each such
indemnified party, as incurred, for any legal or other expenses reasonably
incurred by them in connection with

                                       33


investigating or defending any such loss, claim, damage, liability or action;
provided, however, that Devon Energy will not be liable under the indemnity
agreement in this paragraph (c) to the extent that any such loss, claim, damage
or liability arises out of or is based upon any such untrue statement or alleged
untrue statement or omission or alleged omission made in the documents referred
to in clause (i) above in reliance upon and in conformity with written
information furnished to Devon Energy by or on behalf of any Underwriter through
the Representatives specifically for inclusion therein; provided, further that
Devon Energy shall not be liable under the indemnity agreement in this paragraph
(c) to the extent that any such loss, claim, damage or liability arises out of
or is based on any such untrue statement or alleged untrue statement or omission
or alleged omission made in the documents referred to in clause (i) above in
reliance upon and in conformity with written information furnished to Devon
Energy by Kerr-McGee specifically for inclusion therein; and provided, further
Devon Energy shall not be liable to any Underwriter under the indemnity
agreement in this paragraph (c) with respect to the Preliminary Devon Energy
Prospectus to the extent that any such loss, claim, damage or liability of such
Underwriter results from the fact that such Underwriter sold DECS to a person as
to whom it shall be established that there was not sent or given, at or prior to
the written confirmation of such sale, a copy of the Devon Energy Prospectus
(excluding documents incorporated by reference) or of the Devon Energy
Prospectus as then amended or supplemented (excluding documents incorporated by
reference), as the case may be, in any case where such delivery is required by
the Act and where Devon Energy has previously furnished copies thereof in
sufficient quantity to such Underwriter and the loss, claim, damage or liability
of such Underwriter results from an untrue statement or omission of a material
fact contained in the Preliminary Devon Energy Prospectus and corrected in the
Devon Energy Prospectus (excluding documents incorporated by reference) or in
the Devon Energy Prospectus as then amended or supplemented (excluding documents
incorporated by reference). This indemnity agreement will be in addition to any
liability which Devon Energy may otherwise have.

          (d)  Each Underwriter severally and not jointly agrees to indemnify
and hold harmless Kerr-McGee, each of its directors, each of its officers who
signs the Kerr-McGee Registration Statement, and each person who controls
Kerr-McGee within the meaning of either the Act or the Exchange Act, to the same
extent as the foregoing indemnity in paragraph (a) from Kerr-McGee to each
Underwriter, but only with reference to written information furnished to
Kerr-McGee by or on behalf of such Underwriter through the Representatives
specifically for inclusion in the documents referred to in the foregoing
indemnity. This indemnity agreement will be in addition to any liability which
any Underwriter may otherwise have. Kerr-McGee acknowledges that the statements
set forth in the [___ paragraph] of the cover page, in the [__ paragraph] of the
inside cover page and in the ___ paragraph under the heading ["Plan of
Distribution"] in any Preliminary Final Kerr-McGee Prospectus or the Final
Kerr-McGee Prospectus constitute the only information furnished in writing by or
on behalf of the several Underwriters for inclusion in the documents referred to
in the foregoing indemnity.

          (e)  Each Underwriter severally agrees to indemnify and hold harmless
Devon Energy and Kerr-McGee, each of their respective directors, each of their
respective officers who signs the Devon Energy Registration Statement or the
Kerr-McGee Registration Statement, respectively, and each person who controls
Devon Energy or Kerr-McGee within the meaning of either the Act or the Exchange
Act, to the same extent as the foregoing indemnity in paragraph (c) from Devon
Energy to each Underwriter and Kerr-McGee, but only with reference to written

                                       34


information relating to such Underwriter furnished to Devon Energy or Kerr-McGee
by or on behalf of such Underwriter through the Representatives specifically for
inclusion in the documents referred to in the foregoing indemnity.  This
indemnity agreement will be in addition to any liability which any Underwriter
may otherwise have.  Devon Energy acknowledges that the statements set forth in
the [__] paragraph of the inside cover page and under the heading "Plan of
Distribution" in any Preliminary Devon Energy Prospectus or the Devon Energy
Prospectus constitute the only information furnished in writing by or on behalf
of the several Underwriters for inclusion in the documents referred to in the
foregoing indemnity.

          (f)  Promptly after receipt by an indemnified party under this Section
10 of notice of the commencement of any action, such indemnified party will, if
a claim in respect thereof is to be made against the indemnifying party under
this Section 10, notify the indemnifying party in writing of the commencement
thereof; but the failure so to notify the indemnifying party (i) will not
relieve it from any liability under paragraphs (a), (b), (c), (d) or (e) above
unless and to the extent it did not otherwise learn of such action and such
failure results in the forfeiture by the indemnifying party of substantial
rights and defenses and (ii) will not, in any event, relieve the indemnifying
party from any obligations to any indemnified party other than the
indemnification obligation provided in paragraphs (a), (b), (c), (d) or (e)
above.  The indemnifying party shall be entitled to appoint counsel of the
indemnifying party's choice at the indemnifying party's expense to represent the
indemnified party in any action for which indemnification is sought (in which
case the indemnifying party shall not thereafter be responsible for the fees and
expenses of any separate counsel retained by the indemnified party or parties
except as set forth below); provided, that such counsel shall be satisfactory to
the indemnified party.  Notwithstanding the indemnifying party's election to
appoint counsel to represent the indemnified party in an action, the indemnified
party shall have the right to employ separate counsel (including local counsel),
and the indemnifying party shall bear the reasonable fees, costs and expenses of
such separate counsel if (i) the use of counsel chosen by the indemnifying party
to represent the indemnified party would present such counsel with a conflict of
interest, (ii) the actual or potential defendants in, or targets of, any such
action include both the indemnified party and the indemnifying party and the
indemnified party shall have reasonably concluded that there may be legal
defenses available to it and/or other indemnified parties which are different
from or additional to those available to the indemnifying party, or (iii) the
indemnifying party shall not have employed counsel satisfactory to the
indemnified party to represent the indemnified party within a reasonable time
after notice of the institution of such action or (iv) the indemnifying party
shall authorize the indemnified party to employ separate counsel at the expense
of the indemnifying party.  An indemnifying party will not, without the prior
written consent of the indemnified parties, settle or compromise or consent to
the entry of any judgment with respect to any pending or threatened claim,
action, suit or proceeding in respect of which indemnification or contribution
may be sought hereunder (whether or not the indemnified parties are actual or
potential parties to such claim or action) unless such settlement, compromise or
consent includes an unconditional release of each indemnified party from all
liability arising out of such claim, action suit or proceeding.

          (g)  In the event that the indemnity provided in paragraph (a), (b),
(c), (d) or (e) of this Section 10 is unavailable to or insufficient to hold
harmless an indemnified party for any reason, Kerr-McGee, Devon Energy and the
Underwriters agree to contribute to the aggregate losses, claims, damages and
liabilities (including legal or other expenses reasonably incurred in

                                       35


connection with investigating or defending same) (collectively "Losses") to
which Kerr-McGee, Devon Energy and one or more of the Underwriters may be
subject in such proportion as is appropriate to reflect the relative benefits
received by Kerr-McGee, Devon Energy and the Underwriters from the offering of
the DECS; provided, however, that in no case shall any Underwriter (except as
may be provided in any agreement among underwriters relating to the offering of
the DECS) be responsible for any amount in excess of the underwriting discount
or commission applicable to the DECS purchased by such Underwriter hereunder. If
the allocation provided by the immediately preceding sentence is unavailable for
any reason, Kerr-McGee, Devon Energy and the Underwriters severally shall
contribute in such proportion as is appropriate to reflect not only such
relative benefits but also the relative fault of Kerr-McGee, Devon Energy and
the Underwriters in connection with the statements or omissions which resulted
in such Losses as well as any other relevant equitable considerations. Benefits
received by Kerr-McGee or Devon Energy on the one hand and the Underwriters on
the other with respect to such offering shall be deemed to be equal to the total
net proceeds from the offering (before deducting expenses) received by Kerr-
McGee, and the total underwriting discounts and commissions, respectively, in
each case as set forth on the cover page of the Final Kerr-McGee Prospectus.
Relative fault shall be determined by reference to, among other things, whether
any untrue or alleged untrue statement of a material fact or omission or alleged
omission to state a material fact relates to information provided by Kerr-McGee
and Devon Energy on the one hand or the Underwriters on the other, the intent of
the parties and their relative knowledge, access to information and opportunity
to correct or prevent such untrue statement or omission. Kerr-McGee, Devon
Energy and the Underwriters agree that it would not be just and equitable if
contribution were determined by pro rata allocation or any other method of
allocation which does not take account of the equitable considerations referred
to above. Notwithstanding the provisions of this paragraph (g), no person guilty
of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. For purposes of this Section 10, each person who
controls an Underwriter within the meaning of either the Act or the Exchange Act
and each director, officer, employee and agent of an Underwriter shall have the
same rights to contribution as such Underwriter, and each person who controls
Kerr-McGee or Devon Energy within the meaning of either the Act or the Exchange
Act, each officer of Kerr-McGee or Devon Energy who shall have signed the
Registration Statement and each director of Kerr-McGee or Devon Energy shall
have the same rights to contribution as Kerr-McGee or Devon Energy, subject in
each case to the applicable terms and conditions of this paragraph (g).

          (h)  Notwithstanding the foregoing, all agreements between Kerr-McGee
and Devon Energy in connection with the respective rights and the amount of
liability of each party to the other shall remain in full force and effect to
the extent provided therein.

          11.  Default by an Underwriter.  If any one or more Underwriters shall
fail to purchase and pay for any of the DECS agreed to be purchased by such
Underwriter or Underwriters hereunder and such failure to purchase shall
constitute a default in the performance of its or their obligations under this
Agreement, the remaining Underwriters shall be obligated severally to take up
and pay for (in the respective proportions which the principal amount of DECS
set forth opposite their names in Schedule I hereto bears to the aggregate
principal amount of DECS set forth opposite the names of all the remaining
Underwriters) the DECS which the defaulting Underwriter or Underwriters agreed
but failed to purchase; provided, however, that in

                                       36


the event that the aggregate principal amount of DECS which the defaulting
Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of
the aggregate amount of DECS set forth in Schedule I hereto, the remaining
Underwriters shall have the right to purchase all, but shall not be under any
obligation to purchase any, of the DECS, and if such nondefaulting Underwriters
do not purchase all the DECS, this Agreement will terminate without liability to
any nondefaulting Underwriter, Kerr-McGee or Devon Energy. In the event of a
default by any Underwriter as set forth in this Section 11, the Closing Date
shall be postponed for such period, not exceeding five Business Days, as the
Representatives shall determine in order that the required changes in the Kerr-
McGee or Devon Energy Registration Statement and the Final Kerr-McGee or Devon
Energy Prospectus or in any other documents or arrangements may be effected.
Nothing contained in this Agreement shall relieve any defaulting Underwriter of
its liability, if any, to Kerr-McGee, Devon Energy and any nondefaulting
Underwriter for damages occasioned by its default hereunder.

          12.  Termination.  This Agreement shall be subject to termination in
the absolute discretion of the Representatives, by notice given to Kerr-McGee
and Devon Energy prior to delivery of and payment for the DECS, if prior to such
time (i) trading in Kerr-McGee's or Devon Energy's common stock shall have been
suspended by the Commission or trading in securities generally on the New York
Stock Exchange or the AMEX shall have been suspended or limited or minimum
prices shall have been established on either of such Exchanges, (ii) a banking
moratorium shall have been declared either by Federal or New York State
authorities or (iii) there shall have occurred any outbreak or escalation of
hostilities, declaration by the United States of a national emergency, or war,
or other calamity or crisis the effect of which on financial markets is such as
to make it, in the sole judgment of the Representatives, impracticable or
inadvisable to proceed with the offering or delivery of the DECS as contemplated
by the Final Kerr-McGee Prospectus (exclusive of any supplement thereto).

          13.  Representations and Indemnities to Survive.  Subject to the
limitations imposed by any applicable statute of limitations, the respective
agreements, representations, warranties, indemnities and other statements of
Kerr-McGee and Devon Energy or their respective officers and of the Underwriters
set forth in or made pursuant to this Agreement will remain in full force and
effect, regardless of any investigation made by or on behalf of any Underwriter,
Kerr-McGee or Devon Energy or any of the officers, directors, employees, agents
or controlling persons referred to in Section 10 hereof, and will survive
delivery of and payment for the DECS.  The provisions of Sections 9 and 10
hereof shall survive the termination or cancellation of this Agreement.

          14.  Other Agreement.  Nothing herein shall alter the rights and
obligations of Kerr-McGee and Devon Energy under the Registration Rights
Agreement, the terms of which shall survive and shall not be deemed to have been
terminated by any termination of this Underwriting Agreement or the consummation
of the offering of DECS contemplated hereby.

          15.  Notices.  All communications hereunder will be in writing and
effective only on receipt, and, if sent to the Representatives, will be mailed,
delivered or telefaxed to the Salomon Smith Barney Inc. General Counsel (Fax

Section 10 hereof, and no other person will have any right or obligation
hereunder.

          17.  Applicable Law.  This agreement will be governed by and construed
in accordance with the laws of the State of New York applicable to contracts
made and to be performed within the State of New York.
