SUBJECT TO COMPLETION, DATED AUGUST 8, 2017

PRELIMINARY PROSPECTUS SUPPLEMENT
(To Prospectus dated July 14, 2015)

WPX Energy, Inc.

$150,000,000

5.25% Senior Notes due 2024

---

         We are offering $150,000,000 aggregate principal amount of our 5.25% Senior Notes due 2024 (the "notes"). The notes will mature on September 15, 2024. The notes are an additional issuance of our 5.25% Senior Notes due 2024 initially issued under the indenture dated as of September 8, 2014 and will rank equally with and be treated as a single class for all purposes under such indenture with the $500 million aggregate principal amount of such notes already outstanding (the "existing 2024 notes"). Upon completion of this offering, $650,000,000 in aggregate principal amount of such series will be outstanding. Interest will accrue from March 15, 2017, and will be payable on March 15 and September 15 of each year, beginning September 15, 2017.

         We may, at our option, at any time prior to June 15, 2024 (which is the date that is three months prior to the maturity date of the notes), redeem the notes in whole or in part at a specified "make-whole" premium as described under the caption "Description of Notes—Optional Redemption." If we experience specific kinds of changes of control accompanied by a specified ratings decline, we must offer to purchase the notes at prices set forth in this prospectus supplement plus accrued and unpaid interest, as described under the caption "Description of Notes—Change of Control." We also have the option at any time on or after June 15, 2024 (which is the date that is three months prior to the maturity date of the notes) to redeem the notes, in whole or in part, at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest thereon to the redemption date. See "Description of Notes—Optional Redemption."

         The notes will be our unsecured senior obligations and will rank equally with all of our other existing and future unsecured senior indebtedness. The notes will be effectively subordinated to all of our future secured indebtedness to the extent of the value of the assets securing such indebtedness and will be structurally subordinated to all existing and future indebtedness and other liabilities of our subsidiaries. The notes will rank senior to all of our future subordinated indebtedness.

         You should read this prospectus supplement and the accompanying base prospectus carefully before you invest in our notes. Investing in our notes involves risks. See "Risk Factors" beginning on page S-14 for a discussion of certain risks that you should consider in connection with an investment in the notes.

(1)

Plus accrued interest from March 15, 2017 to the closing date, which we expect to be $            in the aggregate.

         The notes will not be listed on any securities exchange or automated quotation system.

         We expect that delivery of the notes will be made to investors in book-entry form through The Depository Trust Company on or about August     , 2017.

         Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these notes or passed upon the adequacy or accuracy of this prospectus supplement. Any representation to the contrary is a criminal offense.

INFORMATION ABOUT THIS PROSPECTUS SUPPLEMENT

        This prospectus supplement is part of a registration statement on Form S-3 that we filed with the Securities and Exchange Commission, or the SEC, as a "well-known seasoned issuer" as defined in Rule 405 under the Securities Act of 1933, as amended, or the Securities Act. By using a shelf registration statement, we may sell, at any time and from time to time, in one or more offerings, any combination of the securities described in this prospectus supplement and the accompanying base prospectus. As allowed by the SEC rules, this prospectus supplement does not contain all of the information included in the registration statement. For further information, we refer you to the registration statement, including its exhibits, as well as the accompanying base prospectus, any documents incorporated by reference herein or therein and any applicable free writing prospectus.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

        This prospectus supplement, the accompanying base prospectus, any free writing prospectus and the documents incorporated by reference herein and in the accompanying base prospectus include forward-looking statements that are subject to a number of risks and uncertainties, many of which are beyond our control. These forward-looking statements relate to anticipated financial performance, management's plans and objectives for future operations, business prospects, outcome of regulatory proceedings, market conditions and other matters.

S-ii

---

Table of Contents

        All statements, other than statements of historical facts, included in any of the foregoing documents that address activities, events or developments that we expect, believe or anticipate will exist or may occur in the future, are forward-looking statements.

        Forward-looking statements can be identified by various forms of words such as "anticipates," "believes," "seeks," "could," "may," "should," "continues," "estimates," "expects," "forecasts," "intends," "might," "goals," "objectives," "targets," "planned," "potential," "projects," "scheduled," "will" or other similar expressions. These forward-looking statements are based on management's beliefs and assumptions and on information currently available to management and include, among others, statements regarding:

•

amounts and nature of future capital expenditures;



•

crude oil, natural gas and natural gas liquids ("NGL") prices and demand;



•

expansion and growth of our business and operations;



•

financial condition and liquidity;



•

business strategy;



•

estimates of proved natural gas and oil reserves;



•

reserve potential;



•

development drilling potential;



•

cash flow from operations or results of operations;



•

acquisitions or divestitures; and



•

seasonality of our business.

        Forward-looking statements are based on numerous assumptions, uncertainties and risks that could cause future events or results to be materially different from those stated or implied in this prospectus supplement, the accompanying base prospectus or the documents incorporated by reference herein or therein. Many of the factors that will determine these results are beyond our ability to control or predict. Specific factors that could cause actual results to differ from results contemplated by the forward-looking statements include, among others, the following:

•

availability of supplies (including the uncertainties inherent in assessing, estimating, acquiring and developing future natural gas and oil reserves), market demand, volatility of prices and the availability and cost of capital;



•

inflation, interest rates, fluctuation in foreign exchange and general economic conditions (including future disruptions and volatility in the global credit markets and the impact of these events on our customers and suppliers);



•

the strength and financial resources of our competitors;



•

development of alternative energy sources;



•

the impact of operational and development hazards;



•

costs of, changes in, or the results of laws, government regulations (including climate change regulation and/or potential additional regulation of drilling and completion of wells), environmental liabilities, litigation and rate proceedings;



•

changes in maintenance and construction costs;



•

changes in the current geopolitical situation;

S-iii

Table of Contents

•

our exposure to the credit risk of our customers;



•

risks related to strategy and financing, including restrictions stemming from our debt agreements, future changes in our credit ratings and the availability and cost of credit;



•

risks associated with future weather conditions;



•

acts of terrorism; and



•

additional risks described in our filings with the SEC.

        All forward-looking statements attributable to us or persons acting on our behalf are expressly qualified in their entirety by the cautionary statements set forth above. Given the uncertainties and risk factors that could cause our actual results to differ materially from those contained in any forward-looking statement, we caution investors not to unduly rely on our forward-looking statements. Forward-looking statements speak only as of the date they are made. We disclaim any obligation to and do not intend to update the above list or to announce publicly the result of any revisions to any of the forward-looking statements to reflect future events or developments, except to the extent required by applicable laws. If we update one or more forward-looking statements, no inference should be drawn that we will make additional updates with respect to those or other forward-looking statements.

        In addition to causing our actual results to differ, the factors listed above and referred to below may cause our intentions to change from those statements of intention set forth in or incorporated by reference in this prospectus supplement or the accompanying base prospectus. Such changes in our intentions may also cause our results to differ. We may change our intentions, at any time and without notice, based upon changes in such factors, our assumptions, or otherwise.

NON-GAAP FINANCIAL MEASURES

        We refer to the term adjusted EBITDAX (as described in "Summary—Summary Historical Consolidated Financial Data") in various places in this prospectus supplement. Adjusted EBITDAX is a supplemental financial measure that is not prepared in accordance with generally accepted accounting principles in the United States, or GAAP. This measure excludes a number of significant items, including our interest expense and depreciation, depletion and amortization expense. Our measurement of adjusted EBITDAX may not be comparable to those of other companies. Please see "Summary—Summary Historical Consolidated Financial Data" for a discussion of our use of such measure and a reconciliation of adjusted EBITDAX to the most closely comparable financial measures calculated in accordance with GAAP.

        We also refer to PV-10 in this prospectus supplement (as described in "Summary—Summary Historical Reserve and Operating Data of WPX"). The present value of estimated future net revenues discounted at an annual rate of 10 percent ("PV-10") is not a GAAP financial measure and is derived from the standardized measure, which is the most directly comparable GAAP financial measure. PV-10 is a computation of the standardized measure on a pre-tax basis. PV-10 is equal to the standardized measure of discounted future net cash flows at the applicable date, before deducting future income taxes, discounted at 10 percent. Please see "Summary—Summary Historical Reserve and Operating Data of WPX" for a discussion of our use of such measure and a reconciliation of PV-10 to the most closely comparable financial measure calculated in accordance with GAAP.

RISK FACTORS

        Before you decide to invest in the notes, you should consider the factors set forth below as well as the risk factors discussed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2016, which is incorporated by reference in this prospectus supplement and the accompanying base prospectus. See "Where You Can Find Additional Information; Incorporation of Certain Documents by Reference."

Risk Factors Relating to the Notes

Our indebtedness could impair our financial condition and our ability to fulfill our debt obligations, including our obligations under the notes.

        As of June 30, 2017, after giving effect to this offering and the Tender Offers, assuming that the Tender Offers are fully subscribed with an aggregate of $150 million of the Tender Notes being purchased pursuant to the Tender Offers, we would have had total indebtedness of $2,645 and an additional $1,090 million available for borrowing under our Credit Facility.

        Our debt service obligations and restrictive covenants in our Credit Facility, the indenture governing our existing notes and the indenture governing the notes offered hereby could have important consequences to you. For example, they could:

•

make it more difficult for us to satisfy our obligations with respect to the notes, which could in turn result in an event of default on the notes;



•

impair our ability to obtain additional financing in the future for working capital, capital expenditures, acquisitions or other purposes;



•

diminish our ability to withstand a continued or future downturn in our business or the economy generally;



•

require us to dedicate a substantial portion of our cash flow from operations to debt service payments, thereby reducing the availability of cash for working capital, capital expenditures, acquisitions, general corporate purposes or other purposes;



•

limit our flexibility in planning for, or reacting to, changes in our business and the industry in which we operate; and



•

place us at a competitive disadvantage compared to our competitors that have proportionately less debt.

        We are not prohibited under the indentures governing our existing notes and the notes offered hereby from incurring additional indebtedness in addition to the notes. Our incurrence of significant additional indebtedness would exacerbate the negative consequences mentioned above and could adversely affect our ability to pay the interest on, and principal of, the notes.

We have a holding company structure in which our subsidiaries conduct our operations and own our operating assets, which may affect our ability to make payments on the notes.

        We have a holding company structure, and our subsidiaries conduct all of our operations and own all of our operating assets. Further, substantially all of our cash flows are generated by the subsidiaries that are guarantors under our Credit Facility. We have no significant assets other than the ownership interests in these subsidiaries. As a result, our ability to make required payments on the notes depends on the performance of our subsidiaries and their ability to distribute funds to us. The ability of our subsidiaries to make distributions to us may be restricted by, among other things, applicable state partnership and limited liability company laws and other laws and regulations. In addition, our subsidiaries are not prohibited by the terms of their respective organizational documents or the notes from incurring indebtedness, and the agreements governing such indebtedness may contain restrictions

S-14

---

Table of Contents

on the ability of our subsidiaries to make distributions to us. The notes will be structurally subordinated to all existing and future indebtedness and other liabilities of our subsidiaries. Moreover, if our subsidiaries were to incur significant amounts of indebtedness, such occurrence may inhibit their operating results, cash flow, and financial condition, and their ability to make distributions to us could suffer. An inability by our subsidiaries to make distributions to us would materially and adversely affect our ability to pay interest on, and the principal of, the notes because we expect distributions we receive from our subsidiaries to represent a significant portion of the cash we use to pay interest on, and the principal of, the notes. If we are unable to obtain the funds necessary to pay the principal amount at maturity of the notes, we may be required to adopt one or more alternatives, such as a refinancing of the notes. We cannot assure you that we would be able to refinance the notes.

Our debt agreements impose restrictions on us that may limit our access to credit and adversely affect our ability to operate our business.

        Our Credit Facility contains various covenants that restrict or limit, among other things, our ability to grant liens to support indebtedness, merge or sell substantially all of our assets, make certain distributions and incur additional debt. In addition, our Credit Facility contains financial covenants and other limitations with which we need to comply. Similarly, the indentures governing our existing notes and the notes offered hereby restrict our ability to grant liens to secure certain types of indebtedness and merge or sell substantially all of our assets. These covenants could adversely affect our ability to finance our future operations or capital needs or engage in, expand or pursue our business activities and prevent us from engaging in certain transactions that might otherwise be considered beneficial to us. Our ability to comply with these covenants may be affected by events beyond our control, including prevailing economic, financial and industry conditions. If market or other economic conditions deteriorate, our current assumptions about future economic conditions turn out to be incorrect or unexpected events occur, our ability to comply with these covenants may be significantly impaired.

        Our failure to comply with the covenants in our debt agreements could result in events of default. Upon the occurrence of such an event of default, the lenders could elect to declare all amounts outstanding under our Credit Facility to be immediately due and payable and terminate all commitments, if any, to extend further credit. Certain payment defaults or an acceleration under one debt agreement could cause a cross-default or cross-acceleration of another debt agreement. Such a cross-default or cross-acceleration could have a wider impact on our liquidity than might otherwise arise from a default or acceleration of a single debt instrument. If an event of default occurs, or if other debt agreements cross-default, and the lenders under the affected debt agreements accelerate the maturity of any loans or other debt outstanding to us, we may not have sufficient liquidity to repay amounts outstanding under such debt agreements. The notes do not contain a cross-acceleration event of default. See "Description of Notes" and "Description of Debt Securities" in the accompanying base prospectus.

        Our ability to repay, extend or refinance our debt obligations and to obtain future credit will depend primarily on our operating performance, which will be affected by general economic, financial, competitive, legislative, regulatory, business and other factors, many of which are beyond our control. Our ability to refinance our debt obligations or obtain future credit will also depend upon the current conditions in the credit markets and the availability of credit generally. If we are unable to meet our debt service obligations or obtain future credit on favorable terms, if at all, we could be forced to restructure or refinance our indebtedness, seek additional equity capital or sell assets. We may be unable to obtain financing or sell assets on satisfactory terms, or at all.

Table of Contents

The notes will be effectively subordinated to any of our secured indebtedness to the extent of the assets securing such indebtedness and structurally subordinated to liabilities and indebtedness of our subsidiaries.

        We have the $1.2 billion Credit Facility, and we may incur secured indebtedness and grant security interests in our properties and assets in the future. Any holders of any secured indebtedness that we have or may incur in the future would have claims with respect to our assets constituting collateral for such indebtedness that are effectively prior to your claims under the notes. In the event of a default on such secured indebtedness or our bankruptcy, liquidation or reorganization, those assets would be available to satisfy obligations with respect to the indebtedness secured thereby before any payment could be made on the notes. Accordingly, any such secured indebtedness would effectively be senior to the notes to the extent of the value of the collateral securing the indebtedness. While the indentures governing our existing notes and the notes offered hereby place some limitations on our ability to create liens, there are significant exceptions to these limitations that will allow us to secure some kinds of indebtedness without equally and ratably securing the notes. To the extent the value of the collateral is not sufficient to satisfy the secured indebtedness, the holders of that indebtedness would be entitled to share with the holders of the notes and the holders of other claims against us with respect to our other assets. Holders of the notes will participate ratably with all holders of our unsecured indebtedness that is deemed to be of the same class as the notes, and potentially with all of our other general creditors, based upon the respective amounts owed to each holder or creditor, in our remaining assets. In any of the foregoing events, we cannot assure you that there will be sufficient assets to pay amounts due on the notes. As a result, holders of notes may receive less than holders of secured indebtedness.

        In addition, the notes are not guaranteed by our subsidiaries and our subsidiaries are generally not prohibited under the indentures governing our existing notes or the notes offered hereby from incurring additional indebtedness. Our subsidiaries are operating entities with substantial liabilities arising in the ordinary course of business. In addition, certain of our subsidiaries are guarantors under our Credit Facility. Substantially all of our cash flows are generated by the subsidiaries that are guarantors under our Credit Facility. As a result, holders of the notes will be structurally subordinated to claims of third-party creditors, including holders of indebtedness and other liabilities, of these subsidiaries. Claims of those other creditors, including trade creditors, secured creditors, governmental authorities and holders of indebtedness or guarantees issued by the subsidiaries, will generally have priority as to the assets of the subsidiaries over claims by the holders of the notes. As a result, rights of payment of holders of our indebtedness, including the holders of the notes, will be structurally subordinated to all those claims of creditors of our subsidiaries.

We may not be able to repurchase the notes upon a Change of Control Triggering Event.

        Upon a change of control of us and a downgrade of the rating of the notes (or if the notes have an investment grade rating at the time of the change of control, such notes are downgraded below an investment grade rating by Moody's Investors Service Inc. and Standard & Poor's Ratings Services), we will be required to make an offer to each holder of notes to repurchase all or any part of such holder's notes at a price equal to 101% of their principal amount, plus accrued and unpaid interest, if any, to the date of purchase. See "Description of Notes—Change of Control." If such events were to occur, we cannot assure you that we will have the financial resources to purchase your new notes, particularly if such events trigger a similar repurchase requirement for, or result in the acceleration of, other existing or future indebtedness. In addition, our ability to repurchase the notes may be limited by law and regulations or the terms of other agreements relating to our indebtedness outstanding at the time. Any failure to purchase the notes as required under the indenture governing the notes would result in a default under the indenture, which could have material adverse consequences for us and the holders of the notes.

S-16

Table of Contents

Our credit ratings may not reflect all risks of your investment in the notes.

        The credit ratings assigned to the notes are not a recommendation to buy, sell or hold the notes and do not address all material risks relating to an investment in the notes, but rather reflect only the view of each rating agency at the time the rating is issued. We cannot assure you that these credit ratings will remain in effect for any given period of time or that a rating will not be lowered, suspended or withdrawn entirely by the applicable rating agencies. An increase in the level of our outstanding indebtedness, or other events that could have an adverse impact on our business, properties, financial condition, results of operations or prospects, may cause the rating agencies to downgrade our debt credit rating generally and the ratings on the notes. Each agency's rating should be evaluated independently of any other agency's rating. Actual or anticipated changes or downgrades in our credit ratings, including any announcement that our ratings are under further review for a downgrade, could affect the trading price for or liquidity of the notes, increase our corporate borrowing costs, limit our access to the capital markets or result in more restrictive covenants in future debt agreements.

The limited covenants applicable to the notes may not provide protection against some events or developments that may affect our ability to repay the notes or the trading prices for the notes.

        The indenture governing the notes, among other things, does not:

•

require us to maintain any financial ratios or specific levels of net worth, revenues, income, cash flow or liquidity and, accordingly, does not protect holders of the notes in the event that we experience significant adverse changes in our results of operations or financial condition;



•

limit our ability to incur indebtedness that is equal in right of payment to the notes;



•

limit our subsidiaries' ability to incur indebtedness, which would rank senior to the notes;



•

restrict our subsidiaries' ability to issue securities or otherwise incur indebtedness that would be senior to our equity interests in our subsidiaries;



•

restrict our ability to repurchase or prepay our securities;



•

restrict our ability to enter into transactions with affiliates; or



•

restrict our ability to make investments or to repurchase or pay dividends or make other payments in respect of our common stock or other securities ranking junior to the notes.

        In addition, the indenture governing the notes allows us to incur (a) an unlimited amount of debt to develop oil, gas, coal or other mineral or timber properties secured by liens on such properties and (b) an unlimited amount of debt to finance advance payments under any contract for oil, natural gas, hydrocarbon or other mineral exploration or development secured by liens on such contracts.

        As a result, you should consider the limited covenants in the indenture governing the notes as a significant factor in evaluating whether to invest in the notes.

There may not be a liquid market for the notes and, if a market does develop, it may not be maintained.

        When the existing 2024 notes were issued, they were a new class of securities for which there was no market. We expect that the notes offered hereby will trade fungibly with the existing 2024 notes. The underwriters have advised us that they intend to make a market for the notes, but they are not obligated to do so and may discontinue market-making activities at any time. Accordingly, there can be no assurance that a liquid market for the notes will develop or be maintained. We do not intend to apply for the notes to be listed on any securities exchange or to arrange for any quotation system to quote them.

The market price of the notes may be volatile.

        The market price of the notes will depend on many factors that may vary over time and some of which are beyond our control, including but not limited to:

•

our financial performance;



•

the amount of indebtedness we and our subsidiaries have outstanding;



•

market interest rates;



•

the market for similar securities;



•

our credit ratings;



•

competition; and



•

general economic conditions.

        As a result of these factors, you may only be able to sell your notes at a price below what you believe to be appropriate, including a price below the price you paid for them.

USE OF PROCEEDS

        We will receive approximately $             million in net proceeds from this offering, after deducting underwriting discounts and estimated offering expenses (but including any accrued interest from March 15, 2017 to the closing date of the notes, which the purchasers of the notes offered hereby must pay to us on the closing date). We intend to use the net proceeds of this offering, together with, if required, borrowings under the Credit Facility, to fund the Tender Offers. Any excess net proceeds will be used for general corporate purposes, which may include the repayment or repurchase of outstanding indebtedness.

DESCRIPTION OF OTHER INDEBTEDNESS

Senior Notes

        We currently have outstanding $500 million aggregate principal amount of 7.50% Senior Notes due 2020 (the "2020 Notes"), $1.1 billion aggregate principal amount of 6.00% Senior Notes due 2022 (the "2022 Notes"), $500 million aggregate principal amount of 8.25% Senior Notes due 2023 (the "2023 Notes") and $500 million aggregate principal amount of the existing 2024 notes (collectively, the "Existing Notes"). The Existing Notes were issued under indentures between us and The Bank of New York Mellon Trust Company, N.A., as trustee.

        The terms of the Existing Notes are substantially similar.

        Optional Redemption.    We have the option prior to July 1, 2020 for the 2020 Notes, October 15, 2021 for the 2022 Notes, June 1, 2023 for the 2023 Notes, and June 15, 2024 for the existing 2024 Notes to redeem some or all of such notes at a specified "make whole" premium as described in the indenture governing the applicable series of Existing Notes to be redeemed. We also have the option at any time or from time to time on or after July 1, 2020 to redeem the 2020 Notes, on or after October 15, 2021 to redeem the 2022 Notes, on or after June 1, 2023 to redeem the 2023 Notes or on or after June 15, 2024, to redeem the existing 2024 Notes, in whole or in part, at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest thereon to the redemption date.

        Change of Control.    If we experience a change of control (as defined in the indentures governing the notes) accompanied by a specified rating decline, we must offer to repurchase the Existing Notes of such series at 101% of their principal amount, plus accrued and unpaid interest.

        Covenants.    The terms of the indentures governing our Existing Notes restrict our ability and the ability of our subsidiaries to incur additional indebtedness secured by liens and our ability to effect a consolidation, merger or sale of substantially all our assets and the assets of our subsidiaries. The indentures also require us to file with the trustee and the SEC certain documents and reports within certain time limits set forth in the indentures. However, these limitations and requirements are subject to a number of important qualifications and exceptions. The indentures do not require the maintenance of any financial ratios or specified levels of net worth or liquidity.

        Events of Default.    Each of the following is an "Event of Default" under the indentures with respect to the Existing Notes of any series:

        (1)   a default in the payment of interest on the Existing Notes when due that continues for 30 days;

        (2)   a default in the payment of the principal of or any premium, if any, on the Existing Notes when due at their stated maturity, upon redemption, or otherwise;

        (3)   failure by us to duly observe or perform any other of the covenants or agreements (other than those described in clause (1) or (2) above) in the indenture, which failure continues for a period of 60 days, or, in the case of the reporting covenant under the indenture, which failure continues for a period of 90 days, after the date on which written notice of such failure has been given to us by the trustee; provided, however, that if such failure is not capable of cure within such 60-day or 90-day period, as the case may be, such 60-day or 90-day period, as the case may be, will be automatically extended by an additional 60 days so long as (i) such failure is subject to cure and (ii) we are using commercially reasonable efforts to cure such failure; and

        (4)   certain events of bankruptcy, insolvency or reorganization described in the indentures.

Credit Facility

        We have a $1.2 billion senior secured revolving credit facility agreement with Wells Fargo Bank, National Association, as Administrative Agent, Lender and Swingline Lender and the other lenders party thereto. The Credit Facility has a maturity date of October 28, 2019. Based on our current credit ratings, a "Collateral Trigger Period" is currently in effect, making the Credit Facility subject to certain financial covenants and a Borrowing Base as described below. The Credit Facility may be used for working capital, acquisitions, capital expenditures and other general corporate purposes. The financial covenants in the Credit Facility may limit our ability to borrow money, depending on the applicable financial metrics at any given time. As of June 30, 2017, there was $25 million in borrowings and there were $66 million of letters of credit issued under the Credit Facility, and we were in compliance with our financial covenants under the credit agreement. Our unused borrowing availability was $1,109 million as of June 30, 2017.

        Borrowing Base.    During a Collateral Trigger Period, loans under the Credit Facility are subject to a borrowing base as calculated in accordance with the provisions of the Credit Facility. As of March 18, 2016, the borrowing base was set at $1.025 billion. It was reaffirmed at $1.025 billion in October 2016 and was increased to $1.2 billion in April 2017 and will remain in effect until the next redetermination date as set forth in the Credit Facility. The borrowing base is recalculated at least every six months per the terms of the Credit Facility.

        Terms and Conditions.    The Credit Facility is currently guaranteed by certain subsidiaries of the Company (excluding subsidiaries holding midstream assets and subsidiaries meeting other customary exclusion criteria), as Guarantors, and secured by substantially all of the Company's and the Guarantors' assets (including oil and gas properties), subject to customary exceptions and carve outs (which shall also exclude midstream assets and the equity interests of subsidiaries holding midstream assets). Such obligations shall terminate on the earlier of any applicable Collateral Trigger Termination Date (as described below) or the date on which all liens held by the Administrative Agent for the benefit of the secured parties are released pursuant to the terms of the Credit Facility.

        The Collateral Trigger Termination Date is the first date, on which:

(1)

(i) the Company's Corporate Rating is BBB- or better by S&P (without negative outlook or negative watch) or (ii) Baa3 or better by Moody's (without negative outlook or negative watch), provided that the other of the two Corporate Ratings is at least BB+ by S&P or Ba1 by Moody's; or



(2)

both (i) the ratio of Consolidated Net Indebtedness to Consolidated EBITDAX (for the most recently ended four consecutive fiscal quarters) is less than or equal to 3.00 to 1.00 and (ii) the Corporate Rating is (A) at least Ba1 by Moody's and at least BB by S&P or (B) at least Ba2 by Moody's and at least BB+ by S&P.

        Following the Collateral Trigger Termination Date, a Collateral Trigger Period may again occur if the Company's Corporate Rating is BB– or lower (or unrated) by S&P or Ba3 or lower (or unrated) by Moody's or upon the Company's election to voluntarily enter into a Collateral Trigger Period.

        Interest and Commitment Fees.    Interest on borrowings under the Credit Facility is payable at rates per annum equal to, at the Company's option: (1) a fluctuating base rate equal to the alternate base rate plus the applicable margin, or (2) a periodic fixed rate equal to LIBOR plus the applicable margin. The alternate base rate will be the highest of (i) the federal funds rate plus 0.5 percent, (ii) the Prime Rate, and (iii) one-month LIBOR plus 1.0 percent. The Company is required to pay a commitment fee based on the unused portion of the commitments under the Credit Facility. The applicable margin and the commitment fees during a Collateral Trigger Period are determined by reference to a utilization percentage as set forth in the Credit Facility. The applicable margin and the commitment fee other

S-22

than during a Collateral Trigger Period are determined by reference to a pricing schedule based on the Company's senior unsecured non-credit enhanced debt ratings.

Significant Financial Covenants.

        Currently, the Company is required to maintain:

•

ratio of Consolidated Secured Indebtedness to Consolidated EBITDAX (for the most recently ended four consecutive fiscal quarters) of not greater than 3.25 to 1.00 as of the last day of any fiscal quarter ending on or before December 31, 2017 and 3.00 to 1.00 thereafter; and



•

a ratio of consolidated current assets (including the unused amount of the Borrowing Base) of the Company and its consolidated subsidiaries to the consolidated current liabilities of the Company and its consolidated subsidiaries as of the last day of any fiscal quarter of at least 1.0 to 1.0.

        Following consummation of this issuance of notes and the Tender Offers, assuming that the Tender Offers are fully subscribed with an aggregate of $150 million of the Tender Notes being purchased pursuant to the Tender Offers, the Company will remain in compliance with the Consolidated Secured Indebtedness to Consolidated EBITDAX ratio requirement.

        If a Collateral Trigger Termination Date occurs, other financial covenants would apply.

        Covenants.    The Credit Facility contains customary representations and warranties and affirmative, negative and financial covenants (as described above) which were made only for the purposes of the Credit Facility and as of the specific date (or dates) set forth therein, and may be subject to certain limitations as agreed upon by the contracting parties. The covenants limit, among other things, the ability of our subsidiaries to incur indebtedness; our ability and the ability of our subsidiaries to grant certain liens, make restricted payments, materially change the nature of our or their business, make investments, guarantees, loans or advances in non-subsidiaries or enter into certain hedging agreements; the ability of our material subsidiaries to enter into certain restrictive agreements; our ability and the ability of our material subsidiaries to enter into certain affiliate transactions; our the ability and the ability of our subsidiaries to redeem any senior notes; and our ability to merge or consolidate with any person or sell all or substantially all of our assets to any person. We and our subsidiaries are also prohibited from using the proceeds under the Credit Facility in violation of Sanctions (as defined in the Credit Facility). In addition, the representations, warranties and covenants contained in the Credit Facility are subject to certain exceptions and/or standards of materiality applicable to the contracting parties.

        Events of Default.    The Credit Facility includes customary events of default, including events of default relating to:

•

non-payment of principal, interest or fees;



•

inaccuracy of representations and warranties in any material respect when made or when deemed made;



•

violation of covenants;



•

cross payment-defaults;



•

cross acceleration;



•

bankruptcy and insolvency events;



•

certain unsatisfied judgments;



•

a change of control; and

S-23

Table of Contents

•

during any secured period, the failure of the collateral documents to be in effect or a lien to be valid and perfected.

        If an event of default with respect to a borrower occurs under the Credit Facility, the lenders will be able to terminate the commitments and accelerate the maturity of the loans of the defaulting borrower under the Credit Facility and exercise other rights and remedies.

DESCRIPTION OF NOTES

        You can find the definitions of certain terms used in this description under the subheading "—Certain Definitions." In this description, the terms "WPX," "we," "us," and "our" refer only to WPX Energy, Inc. and not to any of its Subsidiaries. You should read the following information in conjunction with the statements under "Description of Debt Securities" in the accompanying prospectus. This "Description of Notes" replaces the description of the general terms and provisions of the debt securities set forth in the accompanying prospectus to the extent the terms of the notes described below are inconsistent with the provisions of the debt securities set forth in the accompanying prospectus.

        On September 8, 2014, we issued $500 million aggregate principal amount of our 5.25% senior notes due 2024 (the "existing 2024 notes") under the indenture dated as of September 8, 2014 (the "base indenture"), as supplemented by a supplemental indenture which established the terms of the existing 2024 notes (the "first supplemental indenture") between us and The Bank of New York Mellon Trust Company, N.A., as trustee (the "trustee"). The term "indenture" refers to the base indenture as supplemented by the first supplemental indenture. We will issue $150 million aggregate principal amount of additional 5.25% Senior Notes due 2024 as additional notes under the indenture (the "new 2024 notes" and, together with the existing 2024 notes, the "notes"). The new 2024 notes will rank equally with and have the same terms as the existing 2024 notes. The new 2024 notes will become part of the same series and will be designated by the same CUSIP number as the existing 2024 notes. The new 2024 notes and the existing 2024 notes will be treated as a single series for all purposes under the indenture.

        The terms of the notes include those stated in the indenture and those made part of the indenture by reference to the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"). The following description is a summary of the material provisions of the indenture and the notes. It does not restate those agreements in their entirety. We urge you to read the indenture in its entirety because it, and not this description, defines your rights as holders of the notes. Copies of the indenture are available as set forth under "Where You Can Find Additional Information; Incorporation of Certain Documents by Reference." Certain defined terms used in this description but not defined below under "—Certain Definitions" have the meanings assigned to them in the indenture.

        The registered holder of a note will be treated as the owner of it for all purposes. Only registered holders will have rights under the indenture.

Brief Description of the Notes

        The notes:

•

are our general unsecured obligations;



•

are equal in right of payment with all of our existing and future senior unsecured indebtedness; and



•

are effectively subordinated to any of our senior secured indebtedness and structurally subordinated to all existing and future indebtedness and other obligations of our Subsidiaries, including trade payables.

        As of June 30, 2017, after giving effect to this offering of the notes and the Tender Offers, assuming that the Tender Offers are fully subscribed with an aggregate of $150 million of the Tender Notes being purchased pursuant to the Tender Offers, on June 30, 2017:

•

we would have had total indebtedness of approximately $2,645 (including $500 million in existing 2024 notes and $150 million in aggregate principal amount of the notes offered hereby), none of

S-25

---

Table of Contents

which was subordinated and $44 million of which was secured borrowings under our $1.2 billion Credit Facility;

•

we would have had $1,090 million available for additional borrowing under our Credit Facility; and



•

our Subsidiaries would have had $0 million of outstanding indebtedness (excluding any guarantee by such Subsidiaries under the Credit Facility).

        Substantially all of our cash flows are generated by the subsidiaries that are guarantors under our Credit Facility.

        The indenture permits us to incur additional indebtedness, including additional senior unsecured indebtedness. The indenture also does not restrict the ability of our Subsidiaries to incur additional indebtedness. See "Risk Factors—Our indebtedness could impair our financial condition and our ability to fulfill our debt obligations, including our obligations under the notes" and "Risk Factors—The notes will be effectively subordinated to any of our secured indebtedness to the extent of the assets securing such indebtedness and structurally subordinated to liabilities and indebtedness of our subsidiaries."

Principal, Maturity and Interest

        We will issue the new 2024 notes with an initial maximum aggregate principal amount of $150 million. We previously issued the existing 2024 notes in the aggregate principal amount of $500 million. The notes will mature on September 15, 2024. We will issue the new 2024 notes in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

        Interest on the new 2024 notes will accrue from March 15, 2017 (the most recent date to which interest has been paid on the existing 2024 Notes) at a rate per annum of 5.25%, and will be payable semi-annually in arrears on March 15 and September 15, beginning on September 15, 2017. We will make each interest payment on the notes to the holders of record at the close of business on the immediately preceding March 1 or September 1 (whether or not a Business Day). Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months.

        We may, without the consent of the holders of notes, issue additional notes having the same ranking and the same interest rate, maturity and other terms as the notes, except that interest may accrue from the date of issuance of such additional notes. Any additional notes having such similar terms, together with the existing 2024 notes and the notes offered hereby, will constitute a single series of notes under the indenture; provided that if the additional notes are not fungible for U.S. federal income tax purposes with the initial notes of such series, the additional notes shall be issued under a separate CUSIP number.

Methods of Receiving Payments on the Notes

        We will pay all principal, interest and premium, if any, on the notes in the manner described under "—Same Day Settlement and Payment" below.

Paying Agent and Registrar for the Notes

        The trustee will initially act as paying agent and registrar. We may change the paying agent or registrar without prior notice to the holders of the notes, and we or any of our Subsidiaries may act as paying agent or registrar.

Transfer and Exchange

        A holder may transfer or exchange notes in accordance with the indenture. The registrar and the trustee may require a holder to furnish appropriate endorsements and transfer documents in

S-26

---

Table of Contents

connection with a transfer of notes. No service charges will be imposed by us, the trustee or the registrar for any registration of transfer or exchange of notes, but holders may be required to pay all taxes due on transfer or exchange. We are not required to transfer or exchange any note selected for redemption, except the unredeemed portion of any note being redeemed in part. Also, we are not required to transfer or exchange any note for a period of 15 days before mailing notice of any redemption of notes.

Optional Redemption

        We may, at our option, at any time or from time to time prior to June 15, 2024 (which is the date that is three months prior to the maturity date of the notes) redeem the notes, in whole or in part, upon not less than 30 nor more than 60 days' notice, at a redemption price equal to the greater of:

(1)

100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest thereon to but excluding, the redemption date, and



(2)

as determined by the Quotation Agent, the sum of the present values of the remaining scheduled payments of principal of and interest on the notes to be redeemed (not including any portion of payments of interest accrued as of the redemption date) discounted to the redemption date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate, plus 50 basis points, plus accrued and unpaid interest thereon to but excluding the redemption date (provided, in each case, that interest payments due on or prior to the redemption date will be paid to the record holders of such notes on the relevant record date).

        We also have the option at any time or from time to time on or after June 15, 2024 (which is the date that is three months prior to the maturity date of the notes) to redeem the notes, in whole or in part, at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest thereon to but excluding the redemption date.

Selection and Notice

        If less than all of notes are to be redeemed at any time, the trustee will select such notes for redemption from the outstanding notes not previously called for redemption by such method as the trustee shall deem fair and appropriate; provided that if the notes are represented by one or more global notes, beneficial interests in the notes will be selected for redemption by DTC in accordance with its standard procedures therefor.

        No notes of $2,000 or less can be redeemed in part. Notices of optional redemption will be mailed by first class mail at least 30 but not more than 60 days before the redemption date to each holder of notes to be redeemed at its registered address. Notices of redemption may not be conditional.

        If the notes are to be redeemed in part only, the notice of redemption will state the portion of the principal amount of the notes that are to be redeemed. New notes in principal amount equal to the unredeemed portion of the original notes will be issued in the name of the holders of the notes upon cancellation of the original notes. Notes called for redemption become due on the date fixed for redemption. On and after the redemption date, interest will cease to accrue on notes or portions of them called for redemption.

Change of Control

        If a Change of Control occurs and is accompanied by a Rating Decline (together, a "Change of Control Triggering Event"), each registered holder of notes will have the right to require us to offer to repurchase all or any part (equal to $1,000 or an integral multiple of $1,000 in excess thereof, provided that the unpurchased portion of any note must be in a minimum denomination of $2,000) of such

S-27

---

Table of Contents

holder's notes at a purchase price in cash equal to 101% of the principal amount of such notes plus accrued and unpaid interest, if any, to the date of purchase.

        Within 30 days following any Change of Control Triggering Event, we will mail a notice (the "Change of Control Offer") to each registered holder of notes with a copy to the trustee stating:

(1)

that a Change of Control Triggering Event has occurred and that such holder has the right to require us to purchase such holder's notes at a purchase price in cash equal to 101% of the principal amount of such notes plus accrued and unpaid interest, if any, to the date of purchase (the "Change of Control Payment");



(2)

the repurchase date (which shall be no earlier than 30 days nor later than 60 days from the date such notice is mailed and which may be up to five days after the expiration of the Change of Control Offer) (the "Change of Control Payment Date"); and



(3)

the procedures determined by us, consistent with the indenture, that a holder must follow in order to have its notes repurchased.

        On the Change of Control Payment Date we will, to the extent lawful:

(1)

accept for payment all notes or portions thereof (in integral multiples of $1,000 or an integral multiple of $1,000 in excess thereof; provided that the unpurchased portion of any note must be in a minimum denomination of $2,000) properly tendered and not withdrawn under the Change of Control Offer;



(2)

deposit with the paying agent an amount equal to the Change of Control Payment in respect of all notes or portions thereof so tendered; and



(3)

deliver or cause to be delivered to the trustee the notes so accepted together with an Officers' Certificate stating the aggregate principal amount of such notes or portions thereof being purchased by us.

        The Paying Agent will promptly mail or otherwise deliver to each holder of notes so tendered the Change of Control Payment for such notes, and the trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each holder a new note equal in principal amount to any unpurchased portion of the notes surrendered, if any; provided that each such new note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof.

        If the Change of Control Payment Date is on or after an interest record date and on or before the related interest payment date of notes, accrued and unpaid interest, if any, will be paid to the person in whose name such note is registered at the close of business on such record date, and no additional interest will be payable to holders who tender pursuant to the Change of Control Offer.

        Except as described above with respect to a Change of Control Triggering Event, the indenture does not contain provisions that permit the holders to require that we repurchase or redeem the notes in the event of a takeover, recapitalization or similar transaction.

        We will not be required to make a Change of Control Offer upon a Change of Control Triggering Event if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in the indenture applicable to a Change of Control Offer made by us and purchases all notes validly tendered and not withdrawn under such Change of Control Offer.

        Our and our subsidiaries' current and/or future debt instruments may require that we repay or refinance indebtedness under such debt instruments in the event of a change of control, as defined in such debt instruments. Such change of control provisions may be triggered under such debt instruments prior to the occurrence of a Change of Control Triggering Event, thereby requiring that the

S-28

---

Table of Contents

indebtedness under such debt instruments be repaid or refinanced prior to our repurchasing any notes upon the occurrence of a Change of Control Triggering Event. Moreover, the exercise by the holders of their right to require us to repurchase the notes could cause a default under such debt instruments, even if the Change of Control Triggering Event itself does not, due to the financial effect of such repurchase on us. In such event, we may not be able to satisfy our obligations to repurchase the notes unless we are able to refinance or obtain waivers with respect to such debt instruments.

        Finally, our ability to pay cash to the holders upon a repurchase may be limited by our then existing financial resources. There can be no assurance that sufficient funds will be available when necessary to make any required repurchases.

        Even if sufficient funds were otherwise available, the terms of our current and/or future debt instruments may prohibit our prepayment of notes before their scheduled maturity. Consequently, if we are not able to prepay the indebtedness under such debt instruments or obtain requisite consents, we will be unable to fulfill our repurchase obligations if holders of the notes exercise their repurchase right following a Change of Control Triggering Event, resulting in an Event of Default under the indenture. An Event of Default under the indenture may result in a default under our current and/or future debt instruments.

        We will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control offer provisions of the notes, we will comply with those securities laws and regulations and will not be deemed to have breached our obligations under the Change of Control offer provisions of the notes by virtue of any such conflict.

        The definition of "Change of Control" includes a phrase relating to the sale, lease, transfer, conveyance or other disposition of "all or substantially all" of our assets and those of our Subsidiaries taken as a whole.

        Although there is a limited body of case law interpreting the phrase "substantially all," there is no precise established definition of the phrase under applicable law. Accordingly, in certain circumstances there may be a degree of uncertainty as to whether a particular transaction would involve "all or substantially all" of the properties or assets of a Person.

        In addition, under clause (4) of the definition of Change of Control below, a Change of Control will occur when a majority of the members of the Board of Directors or equivalent governing body of WPX ceases to be composed of individuals (i) who were members of that board or equivalent governing body on the date the notes were issued, (ii) whose election or nomination to that board or equivalent governing body was approved by individuals referred to in clause (i) above constituting at the time of such election or nomination at least a majority of that board or equivalent governing body, or (iii) whose election or nomination to that board or equivalent governing body was approved by individuals referred to in clauses (i) and (ii) above constituting at the time of such election or nomination at least a majority of that board or equivalent governing body (excluding, in the case of both clause (ii) and clause (iii), any individual whose initial nomination for, or assumption of office as, a member of that board or equivalent governing body occurs as a result of an actual or threatened solicitation of proxies or consents for the election or removal of one or more directors by any person or group other than a solicitation for the election of one or more directors by or on behalf of the Board of Directors). A Delaware Court of Chancery decision has held that the occurrence of a change of control under a similar indenture provision may nevertheless be avoided if the existing directors were to approve the slate of new director nominees, provided the existing directors gave their approval in the good faith exercise of their fiduciary duties owed to the corporation and its shareholders. Therefore, in certain circumstances involving a significant change in the composition of our Board of

S-29

Table of Contents

Directors, holders of the Notes may not be entitled to require us to repurchase the Notes as described above.

Mandatory Redemption

        We are not required to make mandatory redemption or sinking fund payments with respect to the notes.

Certain Covenants

        Except as set forth in this "Description of Notes," neither we nor any of our Subsidiaries will be restricted by the indenture from incurring additional indebtedness or other obligations, from making distributions or paying dividends on our or our Subsidiaries' equity interests or from purchasing our or our Subsidiaries' equity interests. The indenture does not require the maintenance of any financial ratios or specified levels of net worth or liquidity. In addition, the indenture does not contain any provisions that would require us to repurchase or redeem any of the notes in situations that may adversely affect the creditworthiness of the notes.

Liens

        We will not, and will not permit any Subsidiary of ours to, issue, assume or guarantee any Indebtedness secured by a Lien, other than Permitted Liens, upon any of our or any of our Subsidiaries' property, now owned or hereafter acquired, unless the notes are equally and ratably secured with such Indebtedness until such time as such Indebtedness is no longer secured by a Lien.

        Notwithstanding the preceding paragraph, we may, and may permit any Subsidiary of ours to, issue, assume or guarantee any Indebtedness secured by a Lien, other than a Permitted Lien, without securing the notes; provided that the aggregate principal amount of all Indebtedness of ours and any Subsidiary of ours then outstanding secured by any such Liens (other than Permitted Liens) does not exceed 15% of Consolidated Net Tangible Assets.

Merger, Consolidation and Sale of Assets

        The indenture provides that we may not directly or indirectly consolidate with or merge with or into, or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of our assets and properties and the assets and properties of our Subsidiaries (taken as a whole) in one or more related transactions to another Person (as defined in the indenture), unless:

        (1)   either: (a) we are the survivor; or (b) the Person formed by or surviving any such consolidation or merger (if other than us) or to which such sale, assignment, transfer, lease, conveyance or other disposition has been made is a Person formed, organized or existing under the laws of the United States, any state of the United States or the District of Columbia;

        (2)   the Person formed by or surviving any such consolidation or merger (if other than us) or the Person to which such sale, assignment, transfer, lease, conveyance or other disposition has been made expressly assumes by supplemental indenture, in form reasonably satisfactory to the trustee, executed by the successor person and delivered to the trustee, the due and punctual payment of the principal of and any premium and interest on the debt securities outstanding thereunder and the performance of all of our obligations under the indenture and the debt securities outstanding thereunder;

        (3)   we or the Person formed by or surviving any such merger will deliver to the trustee an officer's certificate and an opinion of counsel, each stating that such consolidation, merger, sale, assignment, transfer, lease, conveyance or other disposition and such supplemental indenture (if

S-30

---

Table of Contents

any) comply with the indenture and that all conditions precedent in the indenture relating to such transaction have been complied with; and

        (4)   immediately after giving effect to such transaction, no event of default or event which, after notice or lapse of time, or both, would become an event of default, shall have occurred and be continuing.

        Upon any consolidation by us with or our merger into any other Person or Persons where we are not the survivor or any sale, assignment, transfer, lease, conveyance or other disposition of all or substantially all of our properties and assets and the properties and assets of our Subsidiaries (taken as a whole) to any Person or Persons in accordance herewith, the successor Person formed by such consolidation or into which we are merged or to which such sale, assignment, transfer, lease, conveyance or other disposition is made shall succeed to, and be substituted for, and may exercise every right and power of, us under the indenture with the same effect as if such successor Person had been named as WPX therein; and thereafter, except in the case of a lease, the predecessor Person shall be released from all obligations and covenants under the indenture and the debt securities.

        Although there is a limited body of case law interpreting the phrase "substantially all," there is no precise established definition of the phrase under applicable law. Accordingly, in certain circumstances there may be a degree of uncertainty as to whether a particular transaction would involve "all or substantially all" of the properties or assets of a Person.

        An assumption of our obligations on the notes and under the indenture by any successor Person might be deemed for U.S. federal income tax purposes to cause an exchange of the notes for new notes by the beneficial owners thereof, resulting in recognition of gain or possible loss for such purposes and possibly other adverse tax consequences to the beneficial owners. You should consult your tax advisors regarding the tax consequences of such an assumption.

Reports

        We will be required to file with the trustee, within 30 days after we have filed the same with the SEC, copies of the annual reports and of the information, documents, and other reports that we are required to file with the SEC pursuant to Section 13 or Section 15(d) of the Exchange Act or pursuant to Section 314 of the Trust Indenture Act. Annual reports, information, documents and reports that are filed by us with the SEC via the EDGAR system or any successor electronic delivery procedure will be deemed to be filed with the trustee at the time such documents are filed via the EDGAR system or such successor procedure. Delivery of such reports, information and documents to the trustee is for informational purposes only, and the trustee's receipt of such will not constitute constructive notice of any information contained therein or determinable from information contained therein, including our compliance with any of our covenants in the indenture.

Events of Default

        Each of the following will constitute an event of default under the indenture with respect to the notes:

        (1)   a default in the payment of interest on the notes when due that continues for 30 days;

        (2)   a default in the payment of the principal of or any premium, if any, on the notes when due at their stated maturity, upon redemption, or otherwise;

        (3)   failure by us duly to observe or perform any other of the covenants or agreements in the indenture (other than a covenant or agreement in respect of the notes a default in whose observance or performance is elsewhere in this "—Events of Default" specifically dealt with), which failure continues for a period of 60 days, or, in the case of any reporting covenant, which

failure continues for a period of 90 days, after the date on which written notice of such failure, requiring the same to be remedied and stating that such notice is a "Notice of Default" has been given to us by the trustee, upon direction of holders of at least 25% in principal amount of then outstanding notes; provided, however, that if such failure is not capable of cure within such 60-day or 90-day period, as the case may be, such 60-day or 90-day period, as the case may be, shall be automatically extended by an additional 60 days so long as (i) such failure is subject to cure, and (ii) we are using commercially reasonable efforts to cure such failure; and

        (4)   certain events of bankruptcy, insolvency or reorganization affecting us.

        In case an event of default specified in clause (1) or (2) above shall occur and be continuing with respect to the notes, holders of at least 25%, and in case an event of default specified in clause (3) above shall occur and be continuing with respect to the notes, holders of at least a majority, in aggregate principal amount of the notes then outstanding may declare the principal amount of all the notes then outstanding under the indenture to be due and payable immediately. If an event of default described in clause (4) above shall occur and be continuing then the principal amount of all the notes then outstanding under the indenture shall be and become due and payable immediately, without notice or other action by any holder or the trustee, to the full extent permitted by law.

        Holders of the notes may not enforce the indenture or the notes except as provided in the indenture. Subject to certain limitations, holders of a majority in principal amount of the then notes may direct the trustee in its exercise of any trust or power with respect to the notes. The indenture provides that the trustee may withhold notice to the holders of the notes of any default with respect to the notes (except in payment of principal of or interest or premium on the notes) if the trustee considers it in the interest of holders to do so.

        Holders of not less than a majority in principal amount of the notes then outstanding by notice to the trustee may on behalf of the holders of all of the notes, waive any past or existing default or event of default under the indenture and its consequences, except a continuing default (a) in the payment of principal of, or interest or premium, if any, on the notes or (b) in respect of a covenant or other provision of the indenture, which under the indenture cannot be modified or amended without the consent of the holder of each outstanding note.

        We are required to deliver to the trustee annually a statement regarding compliance with the indenture.

Same Day Settlement and Payment

        WPX will make payments in respect of the notes represented by the Global Notes (including principal, premium, if any, and interest) by wire transfer of immediately available funds to the accounts specified by DTC or its nominee. WPX will make all payments of principal, premium, if any, and interest with respect to Certificated Notes (i) to holders having an aggregate principal amount of $2,000,000 or less, by check mailed to such holder's registered address or (ii) to holders having an aggregate principal amount of more than $2,000,000, by check mailed to such holder's registered address or, upon application by a holder to the registrar not later than the relevant record date or in the case of payments of principal or premium, if any, not later than 15 days prior to the principal payment date, by wire transfer in immediately available funds to that holder's account within the United States (subject to surrender of the Certificated Note in the case of payments of principal or premium), which application shall remain in effect until the holder notifies the registrar to the contrary in writing. The notes represented by the Global Notes are expected to be eligible to trade in DTC's Same-Day Funds Settlement System, and any permitted secondary market trading activity in such notes will, therefore, be required by DTC to be settled in immediately available funds. WPX expect that secondary trading in any Certificated Notes will also be settled in immediately available funds.

        Because of time zone differences, the securities account of a Euroclear or Clearstream participant purchasing an interest in a Global Note from a Participant will be credited, and any such crediting will be reported to the relevant Euroclear or Clearstream participant, during the securities settlement processing day (which must be a business day for Euroclear and Clearstream) immediately following the settlement date of DTC. DTC has advised WPX that cash received in Euroclear or Clearstream as a result of sales of interests in a Global Note by or through a Euroclear or Clearstream participant to a Participant will be received with value on the settlement date of DTC but will be available in the relevant Euroclear or Clearstream cash account only as of the business day for Euroclear or Clearstream following DTC's settlement date.

BOOK-ENTRY, DELIVERY AND FORM

        The notes offered hereby will initially be issued in registered, global form without interest coupons (the "Global Notes") in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. New 2024 notes will be issued at the closing of this offering only against payment in immediately available funds. The Global Notes will be deposited upon issuance with the trustee as custodian for The Depository Trust Company ("DTC"), and registered in the name of DTC or its nominee, for credit to an account of a direct or indirect participant in DTC as described below.

        Except as set forth below, the Global Notes may be transferred, in whole but not in part, only to DTC, to another nominee of DTC or to a successor of DTC or its nominee. Only in the limited circumstances described below may beneficial interests in the Global Notes be exchanged for definitive notes in registered certificated form ("Certificated Notes") in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. See "—Exchange of Global Notes for Certificated Notes." New 2024 notes will be issued at the closing of this offering only against payment in immediately available funds.

        Transfers of beneficial interests in the Global Notes will be subject to the applicable rules and procedures of DTC and its direct or indirect participants (including, if applicable, those of the Euroclear System ("Euroclear"') and Clearstream Banking, S.A. ("Clearstream")), which may change from time to time.

Depositary Procedures

        The following description of the operations and procedures of DTC, Euroclear and Clearstream are provided solely as a matter of convenience. These operations and procedures are solely within the control of the respective settlement systems and are subject to changes by them. WPX takes no responsibility for these operations and procedures and urge investors to contact the system or their participants directly to discuss these matters.

        DTC has advised WPX that DTC is a limited-purpose trust company created to hold securities for its participating organizations (collectively, the "Participants") and to facilitate the clearance and settlement of transactions in those securities between the Participants through electronic book-entry changes in accounts of its Participants. The Participants include securities brokers and dealers (including the initial purchasers), banks, trust companies, clearing corporations and certain other organizations. Access to DTC's system is also available to other entities such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Participant, either directly or indirectly (collectively, the "Indirect Participants"). Persons who are not Participants may beneficially own securities held by or on behalf of DTC only through the Participants or the Indirect Participants. The ownership interests in, and transfers of ownership interests in, each security held by or on behalf of DTC are recorded on the records of the Participants and Indirect Participants.

        DTC has also advised WPX that, pursuant to procedures established by it:

(1)

upon deposit of the Global Notes, DTC will credit the accounts of the Participants designated by the initial purchasers with portions of the principal amount of the Global Notes; and



(2)

ownership of these interests in the Global Notes will be shown on, and the transfer of ownership of these interests will be effected only through, records maintained by DTC (with respect to the Participants) or by the Participants and the Indirect Participants (with respect to other owners of beneficial interests in the Global Notes).

        DTC has advised WPX that its current practice, upon receipt of any payment in respect of securities such as the notes (including principal and interest), is to credit the accounts of the relevant Participants with the payment on the payment date unless DTC has reason to believe that it will not

S-40

---

Table of Contents

receive payment on such payment date. Each relevant Participant is credited with an amount proportionate to its beneficial ownership of an interest in the principal amount of the relevant security as shown on the records of DTC. Payments by the Participants and the Indirect Participants to the beneficial owners of notes will be governed by standing instructions and customary practices and will be the responsibility of the Participants or the Indirect Participants and will not be the responsibility of DTC, the trustee or WPX. Neither WPX nor the trustee will be liable for any delay by DTC or any of the Participants or the Indirect Participants in identifying the beneficial owners of the notes, and WPX and the trustee may conclusively rely on and will be protected in relying on instructions from DTC or its nominee for all purposes.

        Transfers between the Participants will be effected in accordance with DTC's procedures, and will be settled in same-day funds, and transfers between participants in Euroclear and Clearstream will be effected in accordance with their respective rules and operating procedures.

        Subject to compliance with the transfer restrictions applicable to the notes described herein, cross-market transfers between the Participants, on the one hand, and Euroclear or Clearstream participants, on the other hand, will be effected through DTC in accordance with DTC's rules on behalf of Euroclear or Clearstream, as the case may be, by their respective depositaries; however, such cross-market transactions will require delivery of instructions to Euroclear or Clearstream, as the case may be, by the counterparty in such system in accordance with the rules and procedures and within the established deadlines (Brussels time) of such system. Euroclear or Clearstream, as the case may be, will, if the transaction meets its settlement requirements, deliver instructions to its respective depositary to take action to effect final settlement on its behalf by delivering or receiving interests in the relevant Global Note in DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Euroclear participants and Clearstream participants may not deliver instructions directly to the depositories for Euroclear or Clearstream.

        DTC has advised WPX that it will take any action permitted to be taken by a holder of notes only at the direction of one or more Participants to whose account DTC has credited the interests in the Global Notes and only in respect of such portion of the aggregate principal amount of the notes as to which such Participant or Participants has or have given such direction. However, if there is an Event of Default under the notes, DTC reserves the right to exchange the Global Notes for Certificated Notes, and to distribute such notes to its Participants.

        Although DTC, Euroclear and Clearstream have agreed to the foregoing procedures to facilitate transfers of interests in the Global Notes among participants in DTC, Euroclear and Clearstream, they are under no obligation to perform or to continue to perform such procedures, and may discontinue such procedures at any time. None of WPX, the trustee or any of their respective agents will have any responsibility for the performance by DTC, Euroclear or Clearstream or their respective participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

Exchange of Global Notes for Certificated Notes

        A Global Note is exchangeable for Certificated Notes if:

(1)

DTC (a) notifies WPX that it is unwilling or unable to continue as depositary for the Global Note or (b) has ceased to be a clearing agency registered under the Exchange Act and, in either case, WPX fail to appoint a successor depositary within 90 days;



(2)

WPX, at its option but subject to DTC's requirements, notifies the trustee in writing that it elects to cause the issuance of the Certificated Notes; or



(3)

there has occurred and is continuing an Event of Default, and DTC notifies the Trustee of its decision to exchange such Global Note for Certificated Notes.

MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS

        This section summarizes the material U.S. federal income tax considerations relating to the purchase, ownership, and disposition of the notes. This summary does not provide a complete analysis of all potential tax considerations. The information provided below is based on the Internal Revenue Code of 1986, as amended (referred to herein as the "Code"), Treasury regulations issued under the Code, judicial authority and administrative rulings and practice, all as of the date of this prospectus supplement and all of which are subject to change, possibly on a retroactive basis. As a result, the tax considerations of purchasing, owning or disposing of the notes could differ from those described below. This summary deals only with beneficial owners who purchase the notes on original issuance at the first price at which a substantial portion of the notes is sold for cash (other than to bond houses, brokers or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers) and who hold the notes as "capital assets" within the meaning of Section 1221 of the Code. This summary does not deal with persons in special tax situations, such as financial institutions, insurance companies, S corporations, regulated investment companies, real estate investment trusts, tax-exempt investors, dealers in securities and currencies, traders in securities that elect to use a mark-to-market method of accounting for their securities, controlled foreign corporations, corporations that accumulate earnings to avoid U.S. federal income tax, U.S. expatriates, persons holding notes as a position in a "straddle," "hedge," "conversion transaction," or other integrated transaction for U.S. federal income tax purposes, investors in pass-through entities, or U.S. holders (as defined below) whose functional currency is not the U.S. dollar. Further, this discussion does not address the consequences under U.S. alternative minimum tax rules, U.S. federal estate or gift tax laws, the tax laws of any U.S. state or locality, any non-U.S. tax laws, or any tax laws other than income tax laws. We will not seek a ruling from the Internal Revenue Service (the "IRS") with respect to any of the matters discussed herein and there can be no assurance that the IRS will not challenge one or more of the tax consequences described herein.

        As used herein, the term "U.S. Person" means:

•

an individual that is a citizen or resident of the United States, for U.S. federal income tax purposes;



•

a corporation (or any other entity treated as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia;



•

an estate whose income is includible in gross income for U.S. federal income tax purposes regardless of its source; or



•

a trust, if (i) a court within the United States is able to exercise primary supervision over the administration of the trust and one or more U.S. persons have the authority to control all substantial decisions of the trust or (ii) it has a valid election in effect under applicable Treasury regulations to be treated as a U.S. person.

        As used herein, a "U.S. holder" is a beneficial owner of notes that is, for U.S. federal income tax purposes, a U.S. Person. As used herein, the term "non-U.S. holder" means a beneficial owner, other than a partnership (or entity treated as a partnership for U.S. federal income tax purposes), of notes that is not a U.S. holder.

        If a partnership, including for this purpose any entity treated as a partnership for U.S. federal income tax purposes, is a beneficial owner of notes, the treatment of a partner in the partnership generally will depend upon the status of the partner and upon the activities of the partnership. A holder of notes that is a partnership and partners in such a partnership should consult their independent tax advisors about the U.S. federal income tax consequences of holding and disposing of notes.

S-43

Table of Contents

        Investors should consult their tax advisor concerning the tax consequences of the purchase, ownership and disposition of the notes, including the tax consequences under the laws of any foreign, state, local or other taxing jurisdictions and the possible effects on investors of changes in U.S. federal or other tax laws.

Issue

        We intend to treat the notes as part of the same issue as the existing 2024 notes and, accordingly, such notes are expected to have the same issue date and issue price as such existing 2024 notes.

U.S. holders

Interest

        It is anticipated, and this discussion assumes, that the notes will be issued without original issue discount for U.S. federal income tax purposes. In such case, except as described below with respect to pre-issuance accrued interest, interest on a note will be includable by a U.S. holder as interest income at the time it accrues or is received in accordance with such holder's method of accounting for U.S. federal income tax purposes and will be ordinary income.

Pre-Issuance Accrued Interest

        A portion of a U.S. holder's purchase price for the notes will be allocable to interest that accrued prior to the date the notes are purchased ("pre-issuance accrued interest"). On the first interest payment date, a portion of the interest received in an amount equal to the pre-issuance accrued interest will be treated as a return of the pre-issuance accrued interest and not as a payment of interest on the notes. Accordingly, the amount treated as a return of pre-issuance accrued interest should not be taxable when received. U.S. Holders should consult their tax advisors concerning the tax treatment of pre-issuance accrued interest.

Bond Premium

        If a U.S. holder's initial tax basis in a note (which will generally equal the cost of the note to such holder (excluding amounts allocated to pre-issuance accrued interest)) exceeds the stated principal amount of the note, the note will be treated as having been acquired with "bond premium." A U.S. holder may elect to amortize such bond premium, in which case the amount required to be included in the U.S. holder's income each year with respect to stated interest on the note will be reduced by the amount of amortizable bond premium allocable (based on the note's yield to maturity) to that year. However, because of the optional redemption features of the notes, special rules apply that may reduce, eliminate or defer the amount of bond premium that may be amortized. Any election to amortize bond premium will apply to all bonds (other than bonds the interest on which is excludable from the gross income for U.S. federal income tax purposes) held by a U.S. holder at the beginning of the first taxable year to which the election applies or thereafter acquired by the holder, and is irrevocable without the consent of the IRS. If a U.S. holder does not elect to amortize bond premium, any bond premium on a note will decrease any gain or increase any loss such holder may otherwise recognize on retirement or other disposition of the note.

Sale, Exchange, Redemption, Retirement or Other Taxable Disposition of the Notes

        Upon a sale, exchange, redemption, retirement or other taxable disposition of a note, a U.S. holder will generally recognize gain or loss equal to the difference between (i) the amount realized on the disposition (other than amounts attributable to accrued but unpaid interest, which will, except in the case of pre-issuance accrued interest, be taxed as interest income as discussed above to the extent not previously included in income) and (ii) the U.S. holder's tax basis in the note. A U.S. holder's tax

S-44

Table of Contents

basis in a note generally will equal the cost of the note (excluding amounts allocated to pre-issuance accrued interest), reduced by the amount of any amortizable bond premium previously used to offset such holder's interest income. A U.S. holder's gain or loss will generally constitute capital gain or loss and will be long-term capital gain or loss if the U.S. holder has held such note for longer than one year. The deductibility of capital losses is subject to certain limitations. Net long-term capital gain recognized by a non-corporate U.S. holder is generally taxed at preferential rates.

Medicare Tax

        U.S. holders who are individuals, estates or certain trusts are required to pay an additional 3.8% Medicare tax on the lesser of (1) the U.S. holder's "net investment income" (or undistributed "net investment income" in the case of estates and trusts) for the relevant taxable year and (2) the excess of the U.S. holder's modified gross income for the taxable year over a certain threshold (which in the case of individuals will be between $125,000 and $250,000 depending on the individual's circumstances). Net investment income will generally include interest income and net gains from the disposition of the notes, unless such interest income or net gains are derived in the ordinary course of the conduct of a trade or business (other than a trade or business that consists of certain passive or trading activities). A U.S. holder that is an individual, estate or trust should consult its tax advisor regarding the applicability of the Medicare tax to its income and gains in respect of its investment in the notes.

Backup Withholding and Information Reporting

        In general, a U.S. holder will be subject to backup withholding at the applicable tax rate with respect to payments of interest or the gross proceeds from dispositions of notes, unless the holder (i) is an entity that is exempt from backup withholding (generally including tax-exempt organizations and certain qualified nominees) and, when required, provides appropriate documentation to that effect or (ii) provides the applicable withholding agent with the holder's social security number or other taxpayer identification number ("TIN"), certifies that the TIN provided is correct and that the holder has not been notified by the IRS that it is subject to backup withholding due to underreporting of interest or dividends, and otherwise complies with applicable requirements of the backup withholding rules. In addition, such payments to U.S. holders that are not exempt entities will generally be subject to information reporting requirements. A U.S. holder who does not provide the applicable withholding agent with the correct TIN may be subject to penalties imposed by the IRS. The amount of any backup withholding from a payment to a U.S. holder will be allowed as a credit against such holder's U.S. federal income tax liability and may entitle such holder to a refund, provided that the required information is timely furnished to the IRS.

Non-U.S. holders

Interest

        Subject to the discussions of backup withholding and the Foreign Account Tax Compliance Act ("FATCA") below, interest income of a non-U.S. holder will qualify for the "portfolio interest exemption" and therefore not be subject to U.S. federal income tax or withholding, provided that:

•

the interest paid on the note is not income that is effectively connected with a United States trade or business carried on by the non-U.S. holder ("ECI");



•

the non-U.S. holder does not actually or constructively (pursuant to the rules of Section 871(h)(3)(C) of the Code) own 10% or more of the total combined voting power of all classes of our stock that are entitled to vote;



•

the non-U.S. holder is not a controlled foreign corporation related to us actually or constructively through the stock ownership rules under Section 864(d)(4) of the Code;

S-45

---

Table of Contents

•

the non-U.S. holder is not a bank that is receiving the interest on an extension of credit made pursuant to a loan agreement entered into in the ordinary course of its business; and



•

the beneficial owner satisfies the certification requirements set forth in Section 871(h) or 881(c), as applicable, of the Code and the Treasury regulations issued thereunder by giving the applicable withholding agent an appropriate IRS Form W-8 (or a suitable substitute or successor form or such other form as the IRS may prescribe) that has been properly completed and duly executed establishing its status as a non-U.S. person or by other means prescribed by the Secretary of the Treasury (or the non-U.S. holder holds the notes through certain foreign intermediaries or certain foreign partnerships, and the non-U.S. holder and the foreign intermediary or foreign partnership satisfy the certification requirements of applicable Treasury regulations).

        If any of these conditions are not met, interest on the notes paid to a non-U.S. holder will generally be subject to U.S. federal withholding tax at a 30% rate unless (a) an applicable income tax treaty reduces or eliminates such tax, and the non-U.S. holder claims the benefit of that treaty by providing an IRS Form W-8BEN or IRS Form W-8BEN-E (or a suitable substitute or successor form or such other form as the IRS may prescribe) that has been properly completed and duly executed, or (b) the interest is ECI and the non-U.S. holder complies with applicable certification requirements by providing an IRS Form W-8ECI (or a suitable substitute or successor form or such other form as the IRS may prescribe) that has been properly completed and duly executed.

        If the interest on the notes is ECI, the non-U.S. holder will be required to pay U.S. federal income tax on that interest on a net income basis generally in the same manner as a U.S. holder (and the 30% withholding tax described above will not apply, provided the appropriate statement is provided to the applicable withholding agent). If, however, a non-U.S. holder is eligible for the benefits of any income tax treaty between the United States and its country of residence, any interest income that is ECI will be subject to U.S. federal income tax in the manner specified by the treaty and will generally be subject to U.S. federal income tax only if such income is attributable to a permanent establishment or a fixed base maintained by the non-U.S. holder in the United States and the non-U.S. holder claims the benefit of the treaty by providing an IRS Form W-8BEN or IRS Form W-8BEN-E (or a suitable substitute or successor form or such other form as the IRS may prescribe) that has been properly completed and duly executed. In addition, interest received by a corporate non-U.S. holder that is ECI may also, under certain circumstances, be subject to an additional "branch profits tax" at a 30% rate, or, if applicable, a lower treaty rate.

Sale, Exchange, Redemption, Retirement or Other Taxable Disposition of the Notes

        Subject to the discussions of backup withholding and FATCA below, a non-U.S. holder will generally not be subject to U.S. federal income tax on any gain realized on a sale, exchange, redemption, retirement or other taxable disposition of the notes unless:

•

the gain is ECI (and, if required by an applicable income tax treaty, is attributable to a U.S. permanent establishment or fixed base maintained by the non-U.S. holder), or



•

in the case of a non-U.S. holder who is a nonresident alien individual, such holder is present in the United States for 183 or more days in the taxable year of the disposition and certain other requirements are met.

        If a non-U.S. holder falls under the first of these exceptions, the holder will be taxed on the net gain derived from the disposition under the graduated U.S. federal income tax rates that are applicable to U.S. Persons and, if the non-U.S. holder is a foreign corporation, it may also be subject to the branch profits tax described above.

S-46

---

Table of Contents

        If an individual non-U.S. holder falls under the second of these exceptions, the holder generally will be subject to U.S. federal income tax at a rate of 30% (or, if applicable, a lower treaty rate) on the gain derived from the disposition, which may be offset by capital losses allocable to sources within the United States for the taxable year of the disposition.

Backup Withholding and Information Reporting

        Generally, the amount of interest paid to a non-U.S. holder and the amount of tax, if any, withheld with respect to those payments must be reported annually to the IRS and to the non-U.S. holder. Copies of the information returns reporting such interest, and any withholding may also be made available to the tax authorities in the country in which the non-U.S. holder resides under the provisions of an applicable income tax treaty. Backup withholding will generally not apply to payments of interest on the notes to a non-U.S. holder if the holder certifies its status as a non-U.S. person under penalties of perjury or otherwise establishes an exemption (provided that the applicable withholding agent does not have actual knowledge or reason to know that the non-U.S. holder is a U.S. Person or that the conditions of any other exemptions are not in fact satisfied).

        The payment of the proceeds of the disposition of notes to or through the United States office of a United States or foreign broker will be subject to information reporting and, depending on the circumstances, backup withholding unless the non-U.S. holder provides the certification described above or otherwise establishes an exemption (and the applicable withholding agent does not have actual knowledge or reason to know that the non-U.S. holder is a U.S. Person or that the conditions of any other exemptions are not in fact satisfied). The payment of the proceeds of a disposition effected outside the United States by a non-U.S. holder to or through a foreign office of a broker generally will not be subject to backup withholding or information reporting. However, if that broker is, for U.S. federal income tax purposes, a U.S. person, a controlled foreign corporation, a foreign person 50% or more of whose gross income from all sources for certain periods is effectively connected with a trade or business in the United States, or a foreign partnership that is engaged in the conduct of a trade or business in the United States or that has one or more partners that are U.S. persons who in the aggregate hold more than 50% of the income or capital interests in the partnership, information reporting requirements will apply unless that broker has documentary evidence in its files of such holder's status as a non-U.S. holder and has no actual knowledge or reason to know to the contrary or unless such holder otherwise establishes an exemption.

        Any amounts withheld from a payment to a non-U.S. holder under the backup withholding rules will be allowed as a credit against such holder's U.S. federal income tax liability and may entitle it to a refund, provided it timely furnishes the required information to the IRS.

FATCA

        Under FATCA, a 30% withholding tax may be imposed on interest on notes paid to a foreign financial institution (including amounts paid to a foreign financial institution on or behalf of a holder) and certain other non-financial foreign entities. Additionally, after December 31, 2018, a 30% withholding tax may apply to gross proceeds from the disposition of the notes that are paid to such persons.

        Withholding under FATCA generally will not apply where such payments are made to (1) a foreign financial institution that undertakes, under either an agreement with the U.S. Treasury or pursuant to an intergovernmental agreement between the jurisdiction in which it is a resident and the U.S. Treasury, to generally identify accounts held by certain U.S. persons and foreign entities with substantial U.S. owners, annually report certain information about such accounts and withhold 30% on payments made to non-compliant foreign financial institutions and certain other account holders, (2) a non-financial foreign entity that either certifies it does not have any substantial U.S. owners or

S-47

---

Table of Contents

furnishes identifying information regarding each substantial U.S. owner, or (3) a foreign financial institution or a non-financial foreign entity that otherwise qualifies for an exemption from these rules.

        Investors should consult their tax advisors regarding FATCA and the regulations thereunder.

        The U.S. federal tax discussion set forth above as to both U.S. holders and non-U.S. holders is included for general information only and may not be applicable depending upon a holder's particular situation. Holders should consult their tax advisors with respect to the tax consequences to them of the purchase, ownership and disposition of the notes, including the tax consequences under state, local, foreign and other tax laws and the possible effects of changes in U.S. federal or other tax laws.

UNDERWRITING

        Subject to the terms and conditions in the underwriting agreement dated the date of this prospectus supplement by and among us and the underwriters named below, for whom Wells Fargo Securities, LLC is acting as representative, we have agreed to sell to each of the underwriters, and each of the underwriters has agreed to purchase from us, severally and not jointly, the principal amount of the notes set forth opposite the underwriter's name.

        The underwriting agreement provides that the obligation of the underwriters to purchase the notes included in this offering is subject to approval of legal matters by counsel and certain other conditions. Under the terms and conditions of the underwriting agreement, if the underwriters purchase any of the notes, then they are obligated to purchase all of the notes.

        The underwriters propose to offer the notes initially at the public offering price on the cover page of this prospectus supplement. After the initial offering of the notes to the public, the public offering price and other selling terms to dealers may be changed. The underwriters may offer and sell notes through certain of their affiliates.

        We have agreed not to offer or sell any of our debt securities (other than the notes) for a period of 45 days after the date of this prospectus supplement without the prior written consent of Wells Fargo Securities, LLC.

        We estimate that the total expenses of this offering to be paid by us, excluding underwriting discounts, will be approximately $             million.

        In connection with this offering and in compliance with applicable law, the underwriters may engage in over-allotment, stabilizing and syndicate covering transactions and penalty bids in accordance with Regulation M under the Exchange Act:

•

Over-allotment involves syndicate sales in excess of the offering size, which creates a syndicate short position.



•

The underwriters may also effect transactions which stabilize, maintain or otherwise affect the market price of the notes at levels above those which might otherwise prevail in the open market.



•

Such transactions may include placing bids for the notes or effecting purchases of the notes for the purpose of pegging, fixing or maintaining the price of the notes.



•

Syndicate covering transactions involve purchases of the notes in the open market after the distribution has been completed in order to cover syndicate short positions.

        These stabilizing transactions and syndicate covering transactions may have the effect of preventing or retarding a decline in the market price of the notes. They may also cause the price of the notes to be higher than it would otherwise be in the absence of these transactions. These transactions may be effected in the over-the-counter market or otherwise. The underwriters are not required to engage in any of these activities and such activities, if commenced, may be discontinued at any time.

        Neither we nor any of the underwriters makes any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the notes. In addition, neither we nor any of the underwriters makes any representation that the underwriters will

S-49

---

Table of Contents

engage in such transactions or that such transactions, once commenced, will not be discontinued without notice.

        The notes are offered for sale only in those jurisdictions where it is legal to offer them. The offering of the notes by the underwriters is subject to receipt and acceptance and subject to the underwriters' right to reject any order in whole or in part.

        When the existing 2024 notes were issued, they were a new class of securities for which there was no market. We expect that the notes offered hereby will trade fungibly with the existing 2024 notes. The underwriters have advised us that they intend to make a market in the notes, as permitted by applicable law. The underwriters are not obligated, however, to make a market in the notes, and may discontinue any market-making activities at any time without notice, in their sole discretion. If the underwriters cease to act as a market-maker for the notes for any reason, there can be no assurance that another firm or person will make a market in the notes. Accordingly, we cannot assure you as to the development or liquidity of any market for these notes. The notes will not be listed on any securities exchange or included in any automated quotation system.

        We have agreed to indemnify the several underwriters against certain liabilities, including liabilities under the Securities Act, the Exchange Act or other Federal or state statutory law or to contribute to payments that the underwriters may be required to make in respect of any such liabilities.

        It is expected that delivery of the notes offered pursuant to this prospectus will be made to investors on or about August             , 2017, which will be the                         business day following the date of this prospectus (such settlement being referred to as "T+            "). Under Rule 15c6-1 of the Exchange Act as currently in effect, trades in the secondary market are required to settle in three business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes prior to three business days before the notes are delivered will be required, by virtue of the fact that the notes initially settle in T+            , to specify an alternate settlement arrangement at the time of any such trade to prevent a failed settlement. Purchasers of the notes who wish to trade such notes prior to their date of delivery hereunder should consult their advisors.

Other Relationships

        Certain of the underwriters and their affiliates have performed investment banking, commercial banking and advisory services for us and our affiliates from time to time for which they have received customary fees and expenses. The underwriters and their affiliates may, from time to time in the future, engage in transactions with and perform services for us and our affiliates in the ordinary course of business. In particular, an affiliate of Wells Fargo Securities, LLC is the administrative agent, lender and swingline lender under the Credit Facility. In addition, certain of the other underwriters or their affiliates are also lenders under the Credit Facility. Certain of the underwriters or their affiliates may also hold our equity or debt securities from time to time. Certain of the underwriters or their affiliates may hold some of the notes being tendered in the Tender Offers. See "Use of Proceeds". Additionally, affiliates of each of the underwriters are lenders under our Credit Facility and accordingly will receive a portion of the proceeds from this offering pursuant to the repayment of borrowings under our Credit Facility.

        Certain of the underwriters or their respective affiliates have a lending relationship with us, and as a result, certain of these underwriters or their respective affiliates routinely hedge and certain of those underwriters or their respective affiliates may hedge their credit exposure to us consistent with their customary risk management policies. Typically, these underwriters and their respective affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the notes offered hereby.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

        This prospectus and the documents incorporated by reference herein and in any prospectus supplement or any free writing prospectus include forward-looking statements that are subject to a number of risks and uncertainties, many of which are beyond our control. These forward-looking statements relate to anticipated financial performance, management's plans and objectives for future operations, business prospects, outcome of regulatory proceedings, market conditions and other matters.

        All statements, other than statements of historical facts, included in any of the foregoing documents that address activities, events or developments that we expect, believe or anticipate will exist or may occur in the future, are forward-looking statements.

        Forward-looking statements can be identified by various forms of words such as "anticipates," "believes," "seeks," "could," "may," "should," "continues," "estimates," "expects," "forecasts," "intends," "might," "goals," "objectives," "targets," "planned," "potential," "projects," "scheduled," "will" or other similar expressions. These forward-looking statements are based on management's beliefs and assumptions and on information currently available to management and include, among others, statements regarding:

•

Amounts and nature of future capital expenditures;



•

Expansion and growth of our business and operations;



•

Financial condition and liquidity;



•

Business strategy;



•

Estimates of proved natural gas and oil reserves;



•

Reserve potential;



•

Development drilling potential;



•

Cash flow from operations or results of operations;



•

Acquisitions or divestitures;



•

Seasonality of our business; and



•

Natural gas, NGLs and crude oil prices and demand.

        Forward-looking statements are based on numerous assumptions, uncertainties and risks that could cause future events or results to be materially different from those stated or implied in this prospectus or the documents incorporated by reference herein. Many of the factors that will determine these results are beyond our ability to control or predict. Specific factors that could cause actual results to differ from results contemplated by the forward-looking statements include, among others, the following:

•

Availability of supplies (including the uncertainties inherent in assessing, estimating, acquiring and developing future natural gas and oil reserves), market demand, volatility of prices and the availability and cost of capital;



•

Inflation, interest rates, fluctuation in foreign exchange and general economic conditions (including future disruptions and volatility in the global credit markets and the impact of these events on our customers and suppliers);



•

The strength and financial resources of our competitors;



•

Development of alternative energy sources;



•

The impact of operational and development hazards;

•

Costs of, changes in, or the results of laws, government regulations (including climate change regulation and/or potential additional regulation of drilling and completion of wells), environmental liabilities, litigation and rate proceedings;



•

Changes in maintenance and construction costs;



•

Changes in the current geopolitical situation;



•

Our exposure to the credit risk of our customers;



•

Risks related to strategy and financing, including restrictions stemming from our debt agreements, future changes in our credit ratings and the availability and cost of credit;



•

Risks associated with future weather conditions;



•

Acts of terrorism; and



•

Additional risks described in our filings with the SEC.

        All forward-looking statements attributable to us or persons acting on our behalf are expressly qualified in their entirety by the cautionary statements set forth above. Given the uncertainties and risk factors that could cause our actual results to differ materially from those contained in any forward-looking statement, we caution investors not to unduly rely on our forward-looking statements. Forward-looking statements speak only as of the date they are made. We disclaim any obligation to and do not intend to update the above list or to announce publicly the result of any revisions to any of the forward-looking statements to reflect future events or developments, except to the extent required by applicable laws. If we update one or more forward-looking statements, no inference should be drawn that we will make additional updates with respect to those or other forward-looking statements.

        In addition to causing our actual results to differ, the factors listed above may cause our intentions to change from those statements of intention set forth in or incorporated by reference in this prospectus. Such changes in our intentions may also cause our results to differ. We may change our intentions, at any time and without notice, based upon changes in such factors, our assumptions or otherwise.

USE OF PROCEEDS

        Unless otherwise stated in the prospectus supplement accompanying this prospectus, we will use the net proceeds from the sale of any securities that may be offered hereby for our general corporate purposes, which may include repayment of indebtedness, acquisitions, working capital, capital expenditures and repurchases of our common stock. Pending any specific application, we may initially invest funds in short-term marketable securities.

RATIO OF EARNINGS TO FIXED CHARGES

        The ratio of earnings to fixed charges has been computed by dividing (i) income (loss) from continuing operations before income taxes and equity earnings, (ii) fixed charges and (iii) distributed income of equity-method investees, excluding proportionate share from 50% owned investees and unconsolidated majority-owned investees less capitalized interest by fixed charges. Fixed charges consist of interest accrued, including proportionate share from 50% owned investees and unconsolidated majority-owned investees and rental expense in an amount deemed to be representative of the interest factor.

        For the periods indicated above, we had no outstanding shares of preferred stock. Therefore, the ratios of earnings to combined fixed charges and preferred stock dividends are identical to the ratios presented in the tables above.

---

(a)

Earnings were inadequate to cover fixed charges by $1,730 million.

(b)

Earnings were inadequate to cover fixed charges by $260 million.

(c)

Earnings were inadequate to cover fixed charges by $887 million.

DESCRIPTION OF CAPITAL STOCK

        The following is a description of the material terms of our capital stock as provided in our amended and restated certificate of incorporation and amended and restated bylaws. We also refer you to our amended and restated certificate of incorporation (including our amendment to our amended and restated certificate of incorporation) and our amended and restated bylaws, copies of which are incorporated by reference as exhibits to the registration statement of which this prospectus forms a part.

Authorized Capitalization

        Our authorized capital stock consists of (i) 2,000,000,000 shares of common stock, par value $0.01 per share and (ii) 100,000,000 shares of preferred stock, par value $0.01 per share. As of June 30, 2015, we had 205,057,581 shares of common stock outstanding and no shares of preferred stock outstanding.

        Authorized but unissued shares of our capital stock may be used for a variety of corporate purposes, including future public offerings, to raise additional capital or to facilitate acquisitions. The Delaware General Corporation Law does not require stockholder approval for any issuance of authorized shares. However, the listing requirements of the New York Stock Exchange, which apply so long as our common stock is listed on the New York Stock Exchange, require stockholder approval of certain issuances equal to or exceeding 20% of the then outstanding voting power or then outstanding number of shares of common stock.

Listing

        Our common stock is listed on the New York Stock Exchange under the symbol "WPX."

Voting Rights

        Each share of our common stock entitles its holder to one vote in the election of each director. No share of our common stock affords any cumulative voting rights. This means that the holders of a majority of the voting power of the shares voting for the election of directors can elect all directors to be elected if they choose to do so, subject to any voting rights granted to holders of any preferred stock. Generally, except as discussed in "—Anti-Takeover Effects of Certificate of Incorporation and Bylaws Provisions," all matters to be voted on by stockholders must be approved by a majority of the total voting power of the common stock present in person or represented by proxy at a meeting at which a quorum exists, subject to any voting rights granted to holders of any preferred stock Except as otherwise provided by law or in the amended and restated certificate of incorporation (as further discussed in "—Anti-Takeover Effects of Certificate of Incorporation and Bylaws Provisions"), and subject to any voting rights granted to holders of any outstanding preferred stock, amendments to the amended and restated certificate of incorporation must be approved by a majority of the votes entitled to be cast by the holders of common stock.

Dividends

        Subject to the rights, if any, of holders of any outstanding series of preferred stock, holders of our common stock are entitled to dividends in such amounts and at such times as our board of directors in its discretion may declare out of funds legally available for the payment of dividends. Dividends on our common stock will be paid at the discretion of our board of directors after taking into account various factors, including:

•

our financial condition;



•

our results of operations;



•

our capital requirements and development expenditures;



•

our future business prospects; and



•

any restrictions imposed by future debt instruments.

7

Table of Contents

Other Rights

        On liquidation, dissolution or winding up of WPX, after payment in full of the amounts required to be paid to holders of preferred stock, if any, all holders of common stock are entitled to receive the same amount per share with respect to any distribution of assets to holders of shares of common stock.

        No shares of common stock are subject to redemption or have preemptive rights to purchase additional shares of our common stock or other securities.

Preferred Stock

        Our amended and restated certificate of incorporation authorizes our board of directors to establish one or more series of preferred stock. Unless required by law or by any stock exchange on which our common stock is listed, the authorized shares of preferred stock will be available for issuance without further action by our stockholders. Our board of directors is able to determine, with respect to any series of preferred stock, the terms and rights of that series, including the following:

•

the designation of the series;



•

the number of shares of the series, which our board of directors may, except where otherwise provided in the preferred stock designation, increase or decrease, but not below the number of shares then outstanding;



•

whether dividends, if any, will be cumulative or non-cumulative and the dividend rate of the series;



•

the dates at which dividends, if any, will be payable;



•

the redemption rights, if any, and price or prices, if any, for shares of the series;



•

the terms and amounts of any sinking fund provided for the purchase or redemption of shares of the series;



•

the amounts payable on shares of the series in the event of any voluntary or involuntary liquidation, dissolution or winding-up of the affairs of our company;



•

whether the shares of the series will have conversion privileges and if so, the terms and conditions of such privileges, including provision for adjustment of the conversion rate, if any;



•

restrictions on the issuance of shares of the same series or of any other class or series;



•

the voting rights, if any, of the holders of the series; and



•

any other relative rights, preferences and limitations of such series.

        The preferred stock may be issued from time to time in one or more series. The particular terms of each series being offered will be described in the prospectus supplement relating to that series of preferred stock. You should also refer to our amended and restated certificate of incorporation and to the certificate of designations relating to the series of the preferred stock being offered for the complete terms of that series of preferred stock. The certificate of designations with respect to each series of preferred stock offered will be incorporated by reference as an exhibit to the registration statement of which this prospectus forms a part. Each series of preferred stock will, when issued against full payment of the purchase price relating to a series of preferred stock, be fully paid and nonassessable.

Anti-Takeover Effects of Certificate of Incorporation and Bylaws Provisions

        Some provisions of our amended and restated certificate of incorporation and amended and restated bylaws could make the following more difficult:

•

acquisition of us by means of a tender offer or merger;

8

---

Table of Contents

•

acquisition of us by means of a proxy contest or otherwise; or



•

removal of our incumbent officers and directors.

        These provisions, summarized below, are expected to discourage coercive takeover practices and inadequate takeover bids. These provisions also are designed to encourage persons seeking to acquire control of us to first negotiate with our board of directors. We believe that the benefits of the potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure our company outweigh the disadvantages of discouraging those proposals because negotiation of them could result in an improvement of their terms.

Classified Board

        Our amended and restated certificate of incorporation provides that our board of directors is divided into three classes until the election of directors at the annual meeting of stockholders to be held in 2017. Commencing at the 2015 annual meeting of stockholders, successors to the class of directors whose terms expire at such meeting shall be elected to hold office for a term expiring at the next annual meeting of stockholders and until their successors are elected and qualified. Commencing with the election of directors at the 2017 annual meeting of stockholders, the board of directors shall no longer be divided into classes and all directors shall be elected to hold office for a term expiring at the next annual meeting of stockholders and until their successors are elected and qualified.

Election and Removal of Directors

        A director nominee shall be elected to our board of directors if the votes cast for such nominee's election exceed the votes cast against such nominee's election. Our amended and restated certificate of incorporation requires that directors may only be removed for cause and only by the affirmative vote of not less than 75% of votes entitled to be cast by the outstanding capital stock in the election of our board of directors.

Size of Board and Vacancies

        Our amended and restated certificate of incorporation provides that the number of directors on our board of directors will be fixed exclusively by our board of directors. Newly created directorships resulting from any increase in our authorized number of directors will be filled solely by the vote of our remaining directors in office. Any vacancies in our board of directors resulting from death, resignation, retirement, disqualification, removal from office or other cause will be filled solely by the vote of our remaining directors in office.

Stockholder Action by Written Consent

        Our amended and restated certificate of incorporation does not provide for our stockholders to act by written consent.

Stockholder Meetings

        Our amended and restated certificate of incorporation and amended and restated bylaws provide that a special meeting of our stockholders may be called only by (i) our board of directors or (ii) the chairman of our board of directors with the concurrence of a majority of our board of directors.

Amendments to Certain Provisions of our Bylaws

        Our amended and restated certificate of incorporation and amended and restated bylaws provide that the provisions of our bylaws relating to the calling of meetings of stockholders, notice of meetings of stockholders, stockholder action by written consent, advance notice of stockholder business or director nominations, the

9

---

Table of Contents

authorized number of directors, the classified board structure, the filling of director vacancies or the removal of directors (and any provision relating to the amendment of any of these provisions) may only be amended by the vote of a majority of our entire board of directors or by the vote of holders of at least 75% of the votes entitled to be cast by the outstanding capital stock in the election of our board of directors.

Amendment of Certain Provisions of our Certificate of Incorporation

        The amendment of any of the above provisions in our amended and restated certificate of incorporation requires approval by the vote of a majority of our entire board of directors followed by the vote of holders of at least 75% of the votes entitled to be cast by the outstanding capital stock in the election of our board of directors.

Requirements for Advance Notification of Stockholder Nominations and Proposals

        Our amended and restated bylaws establish advance notice procedures with respect to stockholder proposals and nomination of candidates for election as directors other than nominations made by or at the direction of our board of directors or a committee of our board of directors.

No Cumulative Voting

        Our amended and restated certificate of incorporation and amended and restated bylaws do not provide for cumulative voting in the election of directors.

Undesignated Preferred Stock

        The authorization of our undesignated preferred stock makes it possible for our board of directors to issue our preferred stock with voting or other rights or preferences that could impede the success of any attempt to change control of us. These and other provisions may have the effect of deferring hostile takeovers or delaying changes of control of our management.

Delaware Anti-Takeover Statute

        We are subject to Section 203 of the Delaware General Corporation Law (the "DGCL"). Subject to specific exceptions, Section 203 prohibits a publicly held Delaware corporation from engaging in a "business combination" with an "interested stockholder" for a period of three years after the date of the transaction in which the person became an interested stockholder, unless:

•

the "business combination," or the transaction in which the stockholder became an "interested stockholder" is approved by the board of directors prior to the date the "interested stockholder" attained that status;



•

upon completion of the transaction that resulted in the stockholder becoming an "interested stockholder," the "interested stockholder" owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced (excluding for purposes of determining the voting stock outstanding and not outstanding, voting stock owned by the interested stockholder, those shares owned by persons who are directors and also officers, and employee stock plans in which employee participants do not have the right to determine confidentiality whether shares held subject to the plan will be tendered in a tender or exchange offer); or



•

on or subsequent to the date a person became an "interested stockholder," the "business combination" is approved by the board of directors and authorized at an annual or special meeting of stockholders by the affirmative vote of at least two-thirds of the outstanding voting stock that is not owned by the "interested stockholder."

10

---

Table of Contents

"Business combinations" include mergers, asset sales and other transactions resulting in a financial benefit to the "interested stockholder." Subject to various exceptions, an "interested stockholder" is a person who, together with his or her affiliates and associates, owns, or within the previous three years did own, 15% or more of the corporation's outstanding voting stock These restrictions could prohibit or delay the accomplishment of mergers or other takeover or change in control attempts with respect to us and, therefore, may discourage attempts to acquire us.

Limitations on Liability and Indemnification of Officers and Directors

        The DGCL authorizes corporations to limit or eliminate the personal liability of directors to corporations and their stockholders for monetary damages for breaches of directors' fiduciary duties. Under our amended and restated certificate of incorporation, subject to limitations imposed by the DGCL, no director shall be personally liable to us or our stockholders for monetary damages for breach of fiduciary duty as a director, except for liability:

•

for any breach of the director's duty of loyalty to the corporation or its stockholders;



•

for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law;



•

pursuant to Section 174 of the DGCL (providing for liability of directors for unlawful payment of dividends or unlawful stock purchases or redemptions); or



•

for any transaction from which a director derived an improper personal benefit.

        Our amended and restated bylaws provide that we must indemnify our directors and officers to the fullest extent authorized by the DGCL. We are also expressly authorized to advance certain expenses (including attorneys' fees and disbursements and court costs) and carry directors' and officers' insurance providing indemnification for our directors, officers and certain employees for some liabilities. We believe that these indemnification provisions and insurance are useful to attract and retain qualified directors and executive officers. There is currently no pending material litigation or proceeding involving any of our directors, officers or employees for which indemnification is sought.

Transfer Agent and Registrar

        Computershare Trust Company, N.A. is the transfer agent and registrar for our common stock.

The debt securities will be issued under the indenture, dated as of September 8, 2014, between us and The Bank of New York Mellon Trust Company, N.A., as trustee.

Merger, Consolidation and Sale of Assets

        The indenture provides that we may not directly or indirectly consolidate with or merge with or into, or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of our assets and properties and the assets and properties of our Subsidiaries (as defined in the indenture) (taken as a whole) in one or more related transactions to another Person (as defined in the indenture), unless:

        (1)   either: (a) we are the survivor; or (b) the Person formed by or surviving any such consolidation or merger (if other than us) or to which such sale, assignment, transfer, lease, conveyance or other disposition has been made is a Person formed, organized or existing under the laws of the United States, any state of the United States or the District of Columbia;

        (2)   the Person formed by or surviving any such consolidation or merger (if other than us) or the Person to which such sale, assignment, transfer, lease, conveyance or other disposition has been made expressly assumes by supplemental indenture, in form reasonably satisfactory to the trustee, executed by the successor person and delivered to the trustee, the due and punctual payment of the principal of and any premium and interest on the debt securities outstanding thereunder and the performance of all of our obligations under the indenture and the debt securities outstanding thereunder;

        (3)   we or the Person formed by or surviving any such merger will deliver to the trustee an officer's certificate and an opinion of counsel, each stating that such consolidation, merger, sale, assignment, transfer, lease, conveyance or other disposition and such supplemental indenture (if any) comply with the indenture and that all conditions precedent in the indenture relating to such transaction have been complied with; and

        (4)   immediately after giving effect to such transaction, no event of default or event which, after notice or lapse of time, or both, would become an event of default, shall have occurred and be continuing.

        Upon any consolidation by us with or our merger into any other Person or Persons where we are not the survivor or any sale, assignment, transfer, lease, conveyance or other disposition of all or substantially all of our properties and assets and the properties and assets of our Subsidiaries (taken as a whole) to any Person or Persons in accordance herewith, the successor Person formed by such consolidation or into which we are merged or to which such sale, assignment, transfer, lease, conveyance or other disposition is made shall succeed to, and be substituted for, and may exercise every right and power of, us under the indenture with the same effect as if such successor Person had been named as WPX therein; and thereafter, except in the case of a lease, the predecessor Person shall be released from all obligations and covenants under the indenture and the debt securities.

        Although there is a limited body of case law interpreting the phrase "substantially all," there is no precise established definition of the phrase under applicable law. Accordingly, in certain circumstances there may be a degree of uncertainty as to whether a particular transaction would involve "all or substantially all" of the properties or assets of a Person.

        An assumption of our obligations on the debt securities and under the indenture by any successor Person might be deemed for U.S. federal income tax purposes to cause an exchange of the debt securities for new debt securities by the beneficial owners thereof, resulting in recognition of gain or possible loss for such purposes and possibly other adverse tax consequences to the beneficial owners. You should consult your tax advisors regarding the tax consequences of such an assumption.

Events of Default

        Unless otherwise specified in the prospectus supplement, each of the following will constitute an event of default under the indenture with respect to debt securities of any series:

        (1)   a default in the payment of interest on the debt securities of such series when due that continues for 30 days;

14

---

Table of Contents

        (2)   a default in the payment of the principal of or any premium, if any, on the debt securities of such series when due at their stated maturity, upon redemption, or otherwise;

        (3)   default in the making or satisfaction of any sinking fund payment or analogous obligation as and when the same shall become due and payable by the terms of the debt securities of such series;

        (4)   failure by us duly to observe or perform any other of the covenants or agreements in the indenture (other than a covenant or agreement in respect of the debt securities of such series a default in whose observance or performance is elsewhere in this "—Events of Default" specifically dealt with), which failure continues for a period of 60 days, or, in the case of any reporting covenant, which failure continues for a period of 90 days, after the date on which written notice of such failure, requiring the same to be remedied and stating that such notice is a "Notice of Default" has been given to us by the trustee, upon direction of holders of at least 25% in principal amount of then outstanding debt securities of such series; provided, however, that if such failure is not capable of cure within such 60-day or 90-day period, as the case may be, such 60-day or 90-day period, as the case may be, shall be automatically extended by an additional 60 days so long as (i) such failure is subject to cure, and (ii) we are using commercially reasonable efforts to cure such failure;

        (5)   certain events of bankruptcy, insolvency or reorganization affecting us; and

        (6)   any other event of default provided with respect to debt securities of that series.

        In case an event of default specified in clause (1), (2) or (3) above shall occur and be continuing with respect to the debt securities of such series, holders of at least 25%, and in case an event of default specified in clause (4) or (6) (unless, in the case of clause (6), otherwise provided for in the applicable series of debt securities) above shall occur and be continuing with respect to the debt securities of such series, holders of at least a majority, in aggregate principal amount of the debt securities of such series then outstanding may declare the principal amount of all the debt securities of such series outstanding under the indenture to be due and payable immediately. If an event of default described in clause (5) above shall occur and be continuing then the principal amount of all the debt securities of such series then outstanding under the indenture shall be and become due and payable immediately, without notice or other action by any holder or the trustee, to the full extent permitted by law.

        Holders of the debt securities may not enforce the indenture or the debt securities except as provided in the indenture. Subject to certain limitations, holders of a majority in principal amount of the then outstanding debt securities of such series may direct the trustee in its exercise of any trust or power with respect to the debt securities of such series. The indenture provides that the trustee may withhold notice to the holders of debt securities of any such series of any default with respect to the debt securities of such series (except in payment of principal of or interest or premium on the debt securities of such series) if the trustee considers it in the interest of holders to do so.

        Holders of not less than a majority in principal amount of the debt securities of such series then outstanding by notice to the trustee may on behalf of the holders of all of the debt securities of such series, waive any past or existing default or event of default under the indenture and its consequences, except a continuing default (a) in the payment of principal of, or interest or premium, if any, on the debt securities of such series or (b) in respect of a covenant or other provision of the indenture, which under the indenture cannot be modified or amended without the consent of the holder of each outstanding debt security of such series.

        We are required to deliver to the trustee annually a statement regarding compliance with the indenture.

Modification and Amendment

        The indenture provides that modifications and amendments may be made by us and the trustee with the consent of the holders of a majority in aggregate principal amount of the outstanding debt securities of each

series affected by the modification or amendment voting as a single class. We may not make any of the following modifications or amendments to the indenture without the consent of the holder of each outstanding debt security of such series affected by the modification or amendment:

        (1)   change the stated maturity of the principal of, or scheduled date for the payment of any installment of interest on, any debt security;

        (2)   reduce the principal amount of, the rate of interest payable on, or any premium payable upon the redemption of, any debt security;

        (3)   change the place of payment for any debt security or the currency in which the principal of, or any premium or interest on, any debt security is payable;

        (4)   impair or affect the right to institute suit for the enforcement of any payment of principal, premium, or interest on or with respect to any debt security on or after the date that such payment has become due and payable;

        (5)   with respect to the debt securities of a series the terms of which provide for the making and consummation of an offer to repurchase such debt securities in connection with a change of control (as defined in such terms), amend, change or modify our obligation to make and consummate such offer to repurchase after the related change of control has occurred, including amending, changing or modifying any definition relating thereto; or

        (6)   reduce the percentage in principal amount of outstanding debt securities of any series the consent of whose holders is required for any supplemental indenture amending or modifying the indenture or any waiver (of certain defaults and their consequences) provided for in the indenture or reduce the requirements contained in the indenture for quorum or voting.

        A supplemental indenture that changes or eliminates any covenant or other provision of the indenture that has been included expressly and solely for the benefit of one or more particular series of debt securities, or that modifies the rights of holders of debt securities of such series with respect to such covenant or other provision, are deemed not to affect the rights under the indenture of the holders of debt securities of any other series.

        The indenture provides that we and the trustee may, at any time and from time to time, without the consent of any holders of the debt securities of any series, enter into one or more supplemental indentures, in form satisfactory to the trustee, for any of the following purposes:

        (1)   to evidence the succession of another person to us, and the assumption by any such successor of our covenants in the indenture and the debt securities;

        (2)   to add to our covenants for the benefit of the holders of all or any series of the debt securities (as shall be specified in such supplemental indenture or indentures) or to surrender any right or power in the indenture conferred on us;

        (3)   to establish the forms or terms of the debt securities;

        (4)   to evidence and provide for acceptance of appointment of a successor trustee under the indenture with respect to the debt securities of one or more series and to add to or change any of the provisions of the indenture as shall be necessary to provide for or facilitate the administration of the trusts under the indenture by more than one trustee;

        (5)   to cure any ambiguity, to correct or supplement any provision in the indenture that may be defective or inconsistent with any other provision of the indenture, or to make any other provisions with respect to matters or questions arising under such indenture; provided that no such action pursuant to this clause (4) shall adversely affect the interests of the holders of the debt securities of any series then outstanding in any material respect;

        (6)   to add any additional events of default with respect to all or any series of debt securities (as shall be specified in such supplement indenture);

Table of Contents

        (7)   to supplement any of the provisions of the indenture to such extent as shall be necessary for the defeasance and discharge of any series of debt securities pursuant to "—Discharge, Legal Defeasance and Covenant Defeasance"; provided that any such action shall not adversely affect the interests of any holder of any outstanding debt security of such series or any other debt security in any material respect;

        (8)   to add guarantees in respect of the debt securities of one or more series and to provide for the terms and conditions of release thereof;

        (9)   to convey, transfer, assign, mortgage or pledge to the trustee as security for the debt securities of one or any series any property or assets and to provide for the terms and conditions of any release thereof;

        (10) to provide for definitive securities in addition to or in place of global securities;

        (11) to provide for the issuance of additional debt securities in accordance with the limitations set forth in the indenture;

        (12) to add to, change or eliminate any of the provisions of the indenture or any indentures supplemental thereto in respect of one or more series of debt securities; provided that any such addition, change or elimination (i) shall not apply to, or modify the rights of any holder of, any such debt securities created prior to the execution of such supplemental indenture, or (ii) shall become effective only when no debt securities created prior to the execution of such supplemental indenture are outstanding;

        (13) to conform the text of the indenture or the debt securities of any series to any provision of the applicable description thereof in the related prospectus or prospectus supplement to the extent that such provision, in our good faith judgment, was intended to be a recitation of a provision of the indenture or such debt securities; or

        (14) to make any other change that does not adversely affect the rights of holders of outstanding debt securities in any material respect.

Discharge, Legal Defeasance and Covenant Defeasance

        The indenture provides that we may satisfy and discharge our obligations under the debt securities of any series and the indenture if:

        (1)   either:

(a)

all debt securities of such series previously authenticated and delivered have been delivered to the trustee for cancellation, except mutilated, lost, stolen or destroyed debt securities that have been replaced or paid and debt securities for whose payment money has been deposited in trust and thereafter repaid to us or discharged from such trust; or



(b)

all such debt securities of such series not delivered to the trustee for cancellation have become due and payable, mature within one year, or are to be called for redemption within one year under arrangements satisfactory to the trustee for giving the notice of redemption and we irrevocably deposit or cause to be deposited in trust with the trustee, as trust funds solely for the benefit of the holders, for such purpose, money in an amount sufficient or governmental obligations, the scheduled payments of principal of and interest on which shall be sufficient, or a combination thereof that shall be sufficient (in the opinion of a nationally recognized independent registered public accounting firm expressed in a written certification thereof delivered to the trustee, which opinion need be given only if governmental obligations have been so deposited) without consideration of any reinvestment to pay and discharge the entire indebtedness on such then outstanding debt securities of such series to maturity or earlier redemption, as the case may be; and

17

Table of Contents

        (2)   we pay or cause to be paid all other sums payable by us under such indenture with respect to outstanding debt securities of such series; and

        (3)   we deliver to the trustee an officers' certificate and an opinion of counsel, in each case stating that all conditions precedent provided for in the indenture relating to the satisfaction and discharge of the indenture have been complied with.

        Notwithstanding such satisfaction and discharge, our obligations to compensate and indemnify the trustee and our and the trustee's obligations to hold funds in trust and to apply such funds pursuant to the terms of the indenture with respect to the debt securities of such series, with respect to issuing temporary debt securities of such series, with respect to the registration, transfer and exchange of debt securities of such series, with respect to the replacement of mutilated, destroyed, lost or stolen debt securities of such series and with respect to the maintenance of an office or agency for payment with respect to the debt securities of such series, shall in each case survive such satisfaction and discharge.

        The indenture provides that (i) we will be deemed to have paid and will be discharged from any and all obligations in respect of the debt securities of such series, and the provisions of the indenture will, except as noted below, no longer be in effect with respect to the debt securities of such series ("defeasance") and (ii) we may, with respect to debt securities of such series, omit to comply with the covenants under "—Merger, Consolidation or Sale of Assets," and (unless otherwise set forth therein) any additional covenants described in the applicable prospectus supplement, and such omission shall be deemed not to be an event of default under clause (3) of the first paragraph of "—Events of Default and Remedies" with respect to the debt securities of such series ("covenant defeasance") and provided that the following conditions shall have been satisfied:

        (1)   we have irrevocably deposited or caused to be deposited in trust with the trustee as trust funds solely for the benefit of the holders of such debt securities of such series, money in an amount sufficient or government obligations, the scheduled payments of principal of and interest on which shall be sufficient, or a combination thereof that shall be sufficient (in the opinion of a nationally recognized independent registered public accounting firm expressed in a written certification thereof delivered to the trustee) without consideration of any reinvestment to pay and discharge the principal of and accrued interest on such then outstanding debt securities of such series to maturity or earlier redemption, as the case may be;

        (2)   such defeasance or covenant defeasance will not result in a breach or violation of, or constitute a default under, the indenture or any other material agreement or instrument to which we are a party or by which we are bound;

        (3)   no event of default or event which with notice or lapse of time would become an event of default with respect to such debt securities of such series shall have occurred and be continuing on the date of such deposit (other than an event of default resulting from non-compliance with any covenant from which we are released upon effectiveness of such defeasance or covenant defeasance as applicable);

        (4)   we shall have delivered to the trustee an opinion of counsel as described in the indenture to the effect that: the holders of the debt securities of such series will not recognize income, gain or loss for federal income tax purposes as a result of our exercise of the option under this provision of the indenture and will be subject to federal income tax on the same amount and in the same manner and at the same times as would have been the case if such deposit and defeasance or covenant defeasance had not occurred;

        (5)   we have delivered to the trustee an officers' certificate and an opinion of counsel, in each case stating that all conditions precedent provided for in the indenture relating to the defeasance or covenant defeasance have been complied with; and

        (6)   if the debt securities of such series are to be redeemed prior to their maturity, notice of such redemption shall have been duly given or provision therefor satisfactory to the trustee shall have been made.

Table of Contents

        Notwithstanding a defeasance or covenant defeasance with respect to the debt securities of such series, our obligations with respect to the following will survive until otherwise terminated or discharged under the terms of the indenture or until no debt securities of such series are outstanding:

        (1)   the rights of holders to receive payments in respect of the principal of, interest on or premium, if any, on such debt securities of such series when such payments are due from the trust referred in clause (1) in the preceding paragraph;

        (2)   the issuance of temporary debt securities, the registration, transfer and exchange of debt securities, the replacement of mutilated, destroyed, lost or stolen debt securities and the maintenance of an office or agency for payment and holding payments in trust with respect to the debt securities;

        (3)   the rights, powers, trusts, duties and immunities of the trustee, and our obligations in connection therewith; and

        (4)   the defeasance provisions of the indenture.

No Personal Liability

        None of any affiliate, director, officer, partner, employee, incorporator, manager or owner of our Capital Stock (as defined in the indenture), as such, will have any liability for any of our obligations under the debt securities of any series, the indenture, or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each holder of debt securities of such series by accepting a debt security waives and releases all such liability. The waiver and release are part of the consideration for issuance of the debt securities of such series. The waiver may not be effective to waive liabilities under the federal securities laws.

Notices

        Notices to holders of the debt securities of any series will be given by mail to the addresses of such holders as they appear in the security register.

Reports

        We will be required to file with the trustee, within 30 days after we have filed the same with the SEC, copies of the annual reports and of the information, documents, and other reports that we are required to file with the SEC pursuant to Section 13 or Section 15(d) of the Exchange Act or pursuant to Section 314 of the Trust Indenture Act. Annual reports, information, documents and reports that are filed by us with the SEC via the EDGAR system or any successor electronic delivery procedure will be deemed to be filed with the trustee at the time such documents are filed via the EDGAR system or such successor procedure. Delivery of such reports, information and documents to the trustee is for informational purposes only, and the trustee's receipt of such will not constitute constructive notice of any information contained therein or determinable from information contained therein, including our compliance with any of our covenants in the indenture.

Title

        We or the trustee may treat the registered owner of any registered debt security as the owner thereof (whether or not the debt security shall be overdue and notwithstanding any notice to the contrary) for the purpose of making payment and for all other purposes.

Governing Law

        The indenture and the debt securities will be governed by, and construed in accordance with, the laws of the State of New York. The indenture is subject to the provisions of the Trust Indenture Act that are required to be a part of the indenture and shall, to the extent applicable, be governed by those provisions.

Concerning the Trustee

        The Bank of New York Mellon Trust Company, N.A. is the trustee under the indenture. If the trustee becomes a creditor of ours, the indenture limits its right to obtain payment of claims in certain cases or to realize on certain property received in respect of any such claim as security or otherwise. The trustee will be permitted to engage in other transactions; however, if the trustee acquires any conflicting interest (as defined in the Trust Indenture Act) after a default has occurred and is continuing, it must eliminate such conflict within 90 days, apply to the Securities and Exchange Commission for permission to continue or resign.

        The holders of a majority in principal amount of the then outstanding debt securities of a series, will have the right to direct the time, method and place of conducting any proceeding for exercising any remedy available to the trustee with respect to the debt securities of such series, subject to certain exceptions. The indenture provides that in case an event of default occurs and is continuing, the trustee will be required, in the exercise of its power, to use the degree of care of a prudent person in the conduct of such person's own affairs. Subject to such provisions, the trustee will be under no obligation to exercise any of its rights or powers under the indenture at the request of any holder of debt securities of a series, unless such holder has offered to the trustee security or indemnity satisfactory to it against any loss, liability or expense.

CERTAIN ERISA CONSIDERATIONS

        Unless otherwise indicated in the applicable prospectus supplement, the following is a summary of certain considerations associated with the purchase of the securities offered under this prospectus by employee benefit plans that are subject to Title I of the U.S. Employee Retirement Income Security Act of 1974, as amended ("ERISA"), plans, individual retirement accounts and other arrangements that are subject to Section 4975 of the Internal Revenue Code of 1986, as amended (the "Code") or provisions under any federal, state, local, non-U.S. or other laws or regulations that are similar to such provisions of the Code or ERISA (collectively, "Similar Laws"), and entities whose underlying assets are considered to include "plan assets" of any such plan, account or arrangement (each, a "Plan").

General Fiduciary Matters

        ERISA and the Code impose certain duties on persons who are fiduciaries of a Plan subject to Title I of ERISA or Section 4975 of the Code (an "ERISA Plan") and prohibit certain transactions involving the assets of an ERISA Plan and its fiduciaries or other interested parties. Under ERISA and the Code, any person who exercises any discretionary authority or control over the administration of such an ERISA Plan or the management or disposition of the assets of such an ERISA Plan, or who renders investment advice for a fee or other compensation to such an ERISA Plan, is generally considered to be a fiduciary of the ERISA Plan.

        In considering an investment in the securities to be offered under this prospectus of a portion of the assets of any Plan, a fiduciary should determine whether the investment is in accordance with the documents and instruments governing the Plan and the applicable provisions of ERISA, the Code or any Similar Law relating to a fiduciary's duties to the Plan including, without limitation, the prudence, diversification, delegation of control and prohibited transaction provisions of ERISA, the Code and any other applicable Similar Laws.

Prohibited Transaction Issues

        Section 406 of ERISA and Section 4975 of the Code prohibit ERISA Plans from engaging in specified transactions involving plan assets with persons or entities who are "parties in interest," within the meaning of ERISA, or "disqualified persons," within the meaning of Section 4975 of the Code, unless an exemption is available. A party in interest or disqualified person who engaged in a non-exempt prohibited transaction may be subject to excise taxes and other penalties and liabilities under ERISA and the Code. In addition, the fiduciary of the ERISA Plan that engaged in such a non-exempt prohibited transaction may be subject to penalties and liabilities under ERISA and the Code. The acquisition and/or holding of securities to be offered under this prospectus by an ERISA Plan with respect to which any of the issuer, the underwriter, or their affiliates is considered a party in interest or a disqualified person may constitute or result in a direct or indirect prohibited transaction under Section 406 of ERISA and/or Section 4975 of the Code, unless the investment is acquired and is held in accordance with an applicable statutory, class or individual prohibited transaction exemption. In this regard, the U.S. Department of Labor (the "DOL") has issued prohibited transaction class exemptions, or "PTCEs," that may apply to the acquisition and holding of the securities to be offered under this prospectus. These class exemptions include, without limitation, PTCE 84-14 respecting transactions determined by independent qualified professional asset managers, PTCE 90-1 respecting insurance company pooled separate accounts, PTCE 91-38 respecting bank collective investment funds, PTCE 95-60 respecting life insurance company general accounts and PTCE 96-23 respecting transactions determined by in-house asset managers. In addition, Section 408(b)(17) of ERISA and Section 4975(d)(20) of the Code provide relief from the prohibited transaction provisions of ERISA and Section 4975 of the Code for certain transactions, provided that neither the issuer of the securities to be offered under this prospectus nor any of its affiliates (directly or indirectly) have or exercise any discretionary authority or control or render any investment advice with respect to the assets of any ERISA Plan involved in the transaction and provided further that the ERISA Plan pays no more than adequate consideration in connection with the transaction. There can be no assurance that all of the conditions of any such exemptions will be satisfied.

21

Table of Contents

        Because of the foregoing, the securities to be offered under this prospectus should not be purchased or held by any person investing "plan assets" of any Plan, unless such purchase and holding will not constitute a non-exempt prohibited transaction under ERISA and the Code or similar violation of any applicable Similar Laws.

Representation

        Accordingly, by acceptance of a security, each purchaser and subsequent transferee of a security will be deemed to have represented and warranted that either (i) no portion of the assets used by such purchaser or transferee to acquire and hold the securities constitutes assets of any Plan or (ii) the purchase and holding of the securities by such purchaser or transferee will not constitute a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code or similar violation under any applicable Similar Laws.

        The foregoing discussion is general in nature and is not intended to be all inclusive. Due to the complexity of these rules and the penalties that may be imposed upon persons involved in non-exempt prohibited transactions, it is particularly important that fiduciaries, or other persons considering purchasing the securities on behalf of, or with the assets of, any Plan, consult with their counsel regarding the potential applicability of ERISA, Section 4975 of the Code and any Similar Laws to such investment and whether an exemption would be applicable to the purchase and holding of the securities.
