TABLE OF CONTENTS

i

ABOUT THIS PROSPECTUS

This prospectus is part of an “automatic shelf” registration statement that we filed with the Securities and Exchange Commission (the “SEC”), as a “well-known seasoned issuer” as defined in Rule 405 under the Securities Act of 1933, as amended (the “Securities Act”), using a “shelf” registration process. Using this process, we may sell the different types of securities described in this prospectus in one or more offerings. This prospectus provides you with a general description of us and the securities we may offer. Each time we sell securities, we will provide a prospectus supplement that will contain specific information about the offering and the terms of the securities being offered. The prospectus supplement may also add, update, or change the information contained or incorporated by reference in this prospectus. If there is any inconsistency between the information in this prospectus and any prospectus supplement, you should rely on the information in the prospectus supplement. Before investing in any of our securities, you should carefully read this prospectus and any applicable prospectus supplement in addition to the information contained in the documents we refer to under the heading “Where You Can Find More Information” and “Incorporation by Reference.”

You should rely only on the information contained in or incorporated by reference in this prospectus and in any applicable prospectus supplement. We have not authorized anyone else to provide you with different or additional information or to make any representations other than those contained in this prospectus and in any applicable prospectus supplement.

You should assume that the information contained in this prospectus, any prospectus supplement, or any document incorporated by reference in this prospectus or any prospectus supplement is accurate only as of the date of the document in which such information is contained or such other date as may be specifically referred to in such document, regardless of the time of any sale or issuance of a security. Our business, financial condition, results of operations, and prospects may have changed since the date indicated on the cover page of such documents.

The distribution of this prospectus may be restricted by law in certain jurisdictions. You should inform yourself about and observe these restrictions. We are not making an offer of any securities in any jurisdiction where the offer is not permitted, and this prospectus does not constitute, and may not be used in connection with, an offer or solicitation by anyone in any jurisdiction in which the offer or solicitation is not authorized, or in which the person making the offer or solicitation is not qualified to do so, or to any person to whom it is unlawful to make the offer or solicitation.

In this prospectus, references to “APA,” “we,” “us,” “our,” and “the Company” mean APA Corporation and its consolidated subsidiaries, unless otherwise noted.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This prospectus, any accompanying prospectus supplement, and the documents incorporated by reference herein and therein may include “forward-looking statements” within the meaning of Section 27A of the Securities Act and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

These statements involve known and unknown risks, uncertainties, and other factors that may cause our actual results, performance, or achievements to be materially different from any future results, performance, or achievements expressed or implied by the forward-looking statements. In some cases, you can identify forward looking statements by terms such as “anticipate,” “project,” “intend,” “estimate,” “expect,” “believe,” “predict,” “budget,” “projection,” “goal,” “plan,” “forecast,” “prospect,” “target,” “potential,” “continue,” “seek,” “guidance,” “outlook,” “possibly,” “might,” “may,” “will,” “could,” “would,” “should,” or the negative of these terms or similar expressions intended to identify forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking.

Forward-looking statements are not guarantees of performance. Actual events or results may differ materially because of conditions in our markets or other factors. Moreover, we do not, nor does any other person, assume responsibility for the accuracy and completeness of those statements. Unless otherwise required by applicable securities laws, we disclaim any intention or obligation to update any of the forward-looking statements after the date of this prospectus. If we do 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. We disclose important factors that could cause our actual results to differ materially from our expectations under “Risk Factors,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and “Forward-Looking Statements and Risk,” as applicable, in APA’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023 (incorporated by reference in this prospectus) and similar sections in any subsequent filings that we incorporate by reference in this prospectus, which describe risks and factors that could cause results to differ materially from those projected in those forward-looking statements.

Those risk factors may not be exhaustive. We operate in a continually changing business environment, and new risk factors emerge from time to time. We cannot predict these new risk factors, nor can we assess the impact, if any, of these new risk factors on our businesses or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those described in any forward-looking statements. Accordingly, forward-looking statements should not be relied upon as a prediction of actual results.

All forward-looking statements speak only as of the date of the document in which they are contained.

All forward-looking statements, expressed or implied, included in this prospectus, any prospectus supplement, and the documents incorporated by reference herein or therein are qualified in their entirety by this cautionary statement. This cautionary statement should also be considered in connection with any subsequent written or oral forward-looking statements that we or persons acting on our behalf may issue.

In addition, we caution that reserve engineering is a process of estimating oil and natural gas accumulated underground and cannot be measured exactly. Accuracy of reserve estimates depend on a number of factors, including data available at the point in time, engineering interpretation of the data, and assumptions used by the reserve engineers as it relates to price and cost estimates and recoverability. New results of drilling, testing, and production history may result in revisions of previous estimates and, if significant, would impact future development plans. As such, reserve estimates may differ from actual results of oil and natural gas quantities ultimately recovered.

3

DESCRIPTION OF CAPITAL STOCK

The following descriptions of our common stock and preferred stock, together with the additional information included in any applicable prospectus supplement, summarize the material terms and provisions of these types of securities. For the complete terms of our common stock and preferred stock, please refer to our certificate of incorporation and bylaws that are incorporated by reference into the registration statement of which this prospectus forms a part. The terms of these securities may also be affected by the General Corporation Law of the State of Delaware.

Under our amended and restated certificate of incorporation, as amended, our authorized capital stock currently consists of 860,000,000 shares of common stock, $0.625 par value per share, and 10,000,000 shares of preferred stock, no par value. We will describe the specific terms of any common stock or preferred stock we may offer in a prospectus supplement. If indicated in a prospectus supplement, the terms of any common stock or preferred stock offered under that prospectus supplement may differ from the terms described below.

Common Stock

As of October 31, 2024, we had 369,947,453 shares of common stock issued and outstanding and approximately 8,439,561 shares of common stock reserved for issuance pursuant to various employee benefit plans (including treasury shares authorized for issuance under those plans), and no shares of preferred stock outstanding. The number of shares of common stock issued and outstanding varies from time to time.

Voting

Each share of common stock entitles the holder thereof to one vote on all matters to be voted on by our stockholders. Our common stock does not have cumulative voting rights. As a result, subject to the voting rights of any future holders of preferred stock, persons who hold more than 50% of the outstanding shares of common stock entitled to elect members of our board of directors can elect all of the directors who are up for election in a particular year.

Dividends

If our board of directors declares a dividend, holders of common stock will receive payments from our funds that are legally available to pay dividends. This dividend right, however, is subject to any preferential dividend rights we may grant to future holders of preferred stock.

Liquidation

If we dissolve, the holders of common stock will be entitled to share ratably in all the assets that remain after we pay our liabilities and any amounts we may owe to the persons who hold our preferred stock.

Other Rights and Restrictions

Holders of common stock do not have preemptive rights, and they have no right to convert their common stock into any other securities. Our common stock is not subject to redemption by us. Our certificate of incorporation and bylaws do not restrict the ability of holders of common stock to transfer their shares of common stock. Delaware law provides that, if we make a distribution to our stockholders, other than a distribution of our capital stock, either when we are insolvent or when we would be rendered insolvent, then our stockholders would be required to pay back to us the amount of the distribution we made to them, or the portion of the distribution that causes us to become insolvent as a result of such distribution, as the case may be. There are no sinking fund provisions applicable to the common stock.

4

Fully Paid and Nonassessable

All outstanding shares of common stock are fully paid and nonassessable.

Listing

Our common stock is listed on the Nasdaq Global Select Market under the symbol “APA.”

Transfer Agent and Registrar

The transfer agent and registrar for our common stock is Equiniti Trust Company.

Preferred Stock

General

We have 10,000,000 shares of no par preferred stock authorized, of which 100,000 shares have been designated as Series A Junior Participating Preferred Stock. There are no issued and outstanding shares of Series A Junior Participating Preferred Stock. The remaining shares of preferred stock are undesignated.

Our certificate of incorporation authorizes our board of directors to issue preferred stock in one or more series and to determine the voting rights and dividend rights, dividend rates, liquidation preferences, conversion rights, redemption rights, including sinking fund provisions and redemption prices, and other terms and rights of each series of preferred stock.

Undesignated Preferred Stock

This summary of the undesignated preferred stock discusses terms and conditions that may apply to preferred stock offered under this prospectus. The applicable prospectus supplement will describe the particular terms of each series of preferred stock actually offered. If indicated in the prospectus supplement, the terms of any series may differ from the terms described below.

The following description, together with any applicable prospectus supplement, summarizes all the material terms and provisions of any preferred stock being offered by this prospectus. It does not restate the terms and provisions in their entirety. We urge you to read our certificate of incorporation and the applicable certificate of designation (each, as filed with the SEC) because they, and not this description, define the rights of any holders of preferred stock. We have filed our certificate of incorporation as an exhibit to the registration statement which includes this prospectus. We will incorporate by reference as an exhibit to the registration statement the form of any certificate of designation before the issuance of any series of preferred stock.

The prospectus supplement for any preferred stock that we actually offer pursuant to this prospectus may include some or all of the following terms:

5

Subject to our certificate of incorporation and to any limitations imposed by any then-outstanding preferred stock, we may issue additional series of preferred stock, at any time or from time to time, with such powers, preferences, rights, and qualifications, limitations, or restrictions as the board of directors determines, and without further action of the stockholders, including holders of our then-outstanding preferred stock, if any.

Anti-Takeover Provisions of APA’s Certificate of Incorporation and Bylaws and Applicable Law

Our certificate of incorporation and bylaws include provisions, summarized below, that may have the effect of delaying, deferring, or preventing a takeover of APA. Please refer to our certificate of incorporation and bylaws that are incorporated by reference into the registration statement that includes this prospectus. You may obtain copies at no charge by writing to us at the address listed under the caption “Where You Can Find More Information.”

The provisions of Delaware law described below also may have an anti-takeover effect.

APA’s Certificate of Incorporation and Bylaws

Provisions of our certificate of incorporation and bylaws may delay, defer, prevent, or otherwise discourage transactions involving an actual or potential change in control of us or change in our management, including transactions in which stockholders might otherwise receive a premium for their shares or that stockholders might otherwise deem to be in their best interests. Among other things, the certificate of incorporation and bylaws provide that:

6

In addition, as a Delaware corporation, we are subject to the provisions of Section 203 of the Delaware General Corporation Law, which prohibits us, subject to certain exceptions described below, from engaging in a “business combination” with:

in each case, for three years following the date that the stockholder became an interested stockholder.

A “business combination” includes a merger or sale of more than 10% of our assets. However, the above provisions of Section 203 do not apply if:

DESCRIPTION OF DEPOSITARY SHARES

The following description, together with any applicable prospectus supplement, summarizes all the material terms and provisions of the depositary shares that we may offer under this prospectus and the related deposit agreements and depositary receipts. Specific deposit agreements and depositary receipts will contain additional important terms and provisions. The forms of the applicable deposit agreement and depositary receipt will be incorporated by reference as an exhibit to the registration statement that includes this prospectus before we issue any depositary shares.

This summary of depositary agreements, depositary shares, and depositary receipts relates to terms and conditions applicable to these types of securities generally. The particular terms of any series of depositary shares will be summarized in the applicable prospectus supplement. If indicated in the applicable prospectus supplement, the terms of any series may differ from the terms summarized below.

General

We may elect to offer fractional shares of preferred stock rather than full shares of preferred stock. If so, we will issue “depositary receipts” for these “depositary shares.” Each depositary share will represent a fraction of a share of a particular series of preferred stock. Each holder of a depositary share will be entitled, in proportion to the fraction of preferred stock represented by that depositary share, to all the rights, preferences, and privileges of the preferred stock, including dividend, voting, redemption, conversion, and liquidation rights, if any, and all the limitations of the preferred stock. We will enter into a deposit agreement with a depositary, which will be named in the applicable prospectus supplement.

In order to issue depositary shares, we will issue preferred stock and immediately deposit these shares with the depositary. The depositary will then issue and deliver depositary receipts to the persons who purchase depositary shares. Each whole depositary share issued by the depositary may represent a fraction of a share of preferred stock held by the depositary. The depositary will issue depositary receipts in a form that reflects whole depositary shares, and each depositary receipt may evidence any number of whole depositary shares.

Pending the preparation of definitive engraved depositary receipts, if any, a depositary may, upon our written order, issue temporary depositary receipts, which will temporarily entitle the holders to all the rights pertaining to the definitive depositary receipts. We will bear the costs and expenses of promptly preparing definitive depositary receipts and of exchanging the temporary depositary receipts for such definitive depositary receipts.

The applicable prospectus supplement will identify the depositary’s corporate trust office. Unless otherwise indicated in the prospectus supplement, the depositary will act as transfer agent and registrar for depositary receipts, and, if we redeem shares of preferred stock, the depositary will act as redemption agent for the corresponding depositary receipts.

Dividends and Other Distributions

The depositary will distribute all cash and non-cash distributions it receives with respect to the underlying preferred stock to the record holders of depositary shares in proportion to the number of depositary shares they hold, subject to any obligations of the record holders to file proofs, certificates, and other information and to pay any taxes or other governmental charges. Unless otherwise indicated in the prospectus supplement, the relevant record date for depositary shares will be the same date as the record date for the underlying preferred stock. In the case of any non-cash distribution, we may determine that the distribution cannot be made proportionately or the depositary may determine that it may not be feasible to make the distribution. If so, the depositary may, with our approval, adopt a method it deems equitable and practicable to effect the distribution, including the sale, public or private, of the securities or other non-cash property it receives in the distribution at a place and on terms it deems proper. The amounts distributed by the depositary will be reduced by any amount required to be withheld by us or the depositary on account of taxes.

8

Liquidation Preference

If a series of preferred stock underlying the depositary shares has a liquidation preference, in the event of our voluntary or involuntary liquidation, dissolution, or winding up, holders of depositary shares will be entitled to receive the fraction of the liquidation preference accorded each share of the applicable series of preferred stock, as set forth in the applicable prospectus supplement.

Redemption of Depositary Shares

If the shares of preferred stock that underlie the depositary shares are redeemable and we redeem the preferred stock, the depositary will redeem the depositary shares from the proceeds it receives from the redemption of the preferred stock it holds. The depositary will redeem the number of depositary shares that represent the amount of underlying preferred stock that we have redeemed. The redemption price for depositary shares will be in proportion to the redemption price per share that we paid for the underlying preferred stock. If we redeem less than all of the depositary shares, the depositary will select which depositary shares to redeem by lot or some substantially equivalent method.

After a redemption date is fixed, the depositary shares to be redeemed no longer will be considered outstanding. The rights of the holders of the depositary shares will cease, except for the rights to receive money or other property upon redemption. In order to redeem their depositary shares, holders must surrender their depositary receipts to the depositary.

Voting the Preferred Stock

When the depositary receives notice about any meeting at which the holders of preferred stock are entitled to vote, the depositary will mail the information contained in the notice to the record holders of depositary shares related to that preferred stock. Each record holder of depositary shares on the record date, which will be the same date as the record date for the preferred stock, will be entitled to instruct the depositary on how to vote the shares of preferred stock represented by that holder’s depositary shares. The depositary will endeavor, to the extent practicable, to vote the preferred stock represented by the depositary shares in accordance with these instructions. If the depositary does not receive instructions from the holders of the depositary shares, the depositary will abstain from voting the preferred stock that underlies those depositary shares.

Withdrawal of Preferred Stock

If a holder of depositary receipts surrenders those depositary receipts at the corporate office (as defined in the deposit agreement) of the depositary, or any other office as the depositary may designate, and pays any taxes, charges, or fees, that holder is entitled to delivery at the corporate office of certificates evidencing the number of shares of preferred stock, but only in whole shares, and any money and other property represented by those depositary receipts. If the depositary receipts we deliver evidence a number of depositary shares in excess of the number of whole shares of preferred stock to be withdrawn, the depositary will deliver to us at the same time a new depositary receipt evidencing that excess number of depositary shares. In no event will the depositary deliver fractional shares of preferred stock upon surrender of depositary receipts. We do not expect that there will be any public trading market for the shares of preferred stock except those represented by the depositary shares.

Amendment and Termination of the Deposit Agreement

We and the depositary can agree, at any time, to amend the form of depositary receipt and any provisions of the deposit agreement. If, however, an amendment has a material adverse effect on the rights of the holders of related depositary shares, the holders of at least a majority of the depositary shares then outstanding must first approve the amendment. Every holder of a depositary receipt at the time an amendment becomes effective will be bound by the amended deposit agreement. Subject to any conditions in the deposit agreement or applicable law, no

9

amendment, however, can impair the right of any holder of a depositary share to receive shares of the related preferred stock, or any money or other property represented by the depositary shares, when they surrender their depositary receipts.

Unless otherwise specified in the applicable prospectus supplement, the deposit agreement may be terminated by us or by the depositary if there has been a final distribution in respect of the preferred stock in connection with any liquidation, dissolution, or winding up of APA and that distribution has been distributed to the holders of depositary receipts.

Charges of Depositary

We will pay all transfer and other taxes and the government charges that relate solely to the depositary arrangements. We will also pay the charges of each depositary, including charges in connection with the initial deposit of the related series of preferred stock, the initial issuance of the depositary shares, and all withdrawals of shares of the related series of preferred stock. Holders of depositary shares, however, will be required to pay transfer and other taxes and government charges, as provided in the deposit agreement. If these charges have not been paid by a holder of depositary receipts, the depositary may refuse to transfer depositary shares to such holder, withhold dividends and distributions from such holder, and sell the depositary shares evidenced by such holder’s depositary receipt.

Resignation and Removal of Depositary

The depositary may submit notice of resignation at any time, or we may remove the depositary at any time. However, no resignation or removal will take effect until we appoint a successor depositary and such successor depositary accepts such appointment, which must occur within 60 days after delivery of the notice of resignation or removal. Subject to the terms of the applicable deposit agreement, the successor depositary must be a bank or trust company that has its principal office in the United States and has a combined capital and surplus as set forth in the applicable agreement.

Notices

The depositary will forward to holders of depositary receipts all notices, reports, and other communications, including proxy solicitation materials received from us, that are delivered to the depositary and that we are required to furnish to the holders of the preferred stock. In addition, the depositary will make available for inspection by holders of depositary receipts at the principal office of the depositary, and at such other places as it may from time to time deem advisable, any reports and communications we deliver to the depositary as the holder of preferred stock.

Limitation of Liability

Neither APA nor the depositary will be liable if its ability to perform its obligations under the deposit agreement is prevented or delayed by law or any circumstance beyond its control. Each of APA and the depositary will be obligated to use its best judgment and to act in good faith in performing its duties under the deposit agreement. Each of APA and the depositary will be liable only for its gross negligence and willful misconduct in performing its duties under the deposit agreement. Neither APA nor the depositary will be obligated to appear in, prosecute, or defend any legal proceeding with respect to any depositary receipts, depositary shares, or preferred stock unless it receives what it, in its sole discretion, determines to be a satisfactory indemnity from one or more holders of the depositary shares. Each of APA and the depositary will evaluate any proposed indemnity in order to determine whether the financial protection afforded by the indemnity is sufficient to reduce such party’s risk to a satisfactory and customary level. Each of APA and the depositary may rely on the advice of legal counsel or accountants of its choice. Each may also rely on information provided by persons it believes, in good faith, to be competent and on documents it believes, in good faith, to be genuine.

10

Title

APA, each depositary, and any agent of APA or the applicable depositary may treat the registered owner of any depositary share as the absolute owner of the depositary shares for all purposes, including making payment, regardless of whether any payment in respect of the depositary share is overdue and regardless of any notice to the contrary.

11

We will issue the senior debt securities under the (i) senior indenture, dated as of June 30, 2021, between us and Computershare Trust Company, N.A., as successor to Wells Fargo Bank, National Association, as trustee or (ii) senior indenture, dated as of December 11, 2024, between APA and Regions Bank, as trustee. We will issue the subordinated debt securities under a subordinated indenture to be executed in the future by us and Computershare Trust Company, N.A. or another entity, as trustee. The senior indentures and any such subordinated indenture are together referred to in this section as the “indentures.” The terms of the debt securities will include those stated in the indentures (including any supplemental indentures that specify the terms of a particular series of debt securities) as well as those made part of the indentures by reference to the Trust Indenture Act of 1939, as in effect on the date of the applicable indenture. The indentures will be subject to and governed by the terms of the Trust Indenture Act of 1939. The senior debt securities and the subordinated debt securities are together referred to in this section as the “debt securities.” Computershare Trust Company, N.A., Regions Bank, any future successors, or any other entity with which we execute an indenture, in its capacity as trustee under any of the indentures referenced herein, is referred to as the “trustee” for purposes of this section. The indentures contain and the debt securities, when issued, will contain additional important terms and provisions. The senior indentures are, and prior to their issuance any senior debt securities will be, filed as exhibits to the registration statement that includes this prospectus. Prior to the issuance of any subordinated debt securities, the subordinated indenture and such subordinated debt securities will be filed as exhibits to the registration statement that includes this prospectus. We encourage you to read the indentures, because they, and not this description, control your rights as holders of the debt securities.

This summary of the indentures and the debt securities relates to terms and conditions applicable to the debt securities generally. The applicable prospectus supplement will set forth the particular terms of any series of debt securities that we may offer. If indicated in the prospectus supplement, the terms of any series may differ from the terms summarized below.

No indenture referenced herein limits the amount of debt securities we may issue under it, and each provides that additional debt securities of any series may be issued up to the aggregate principal amount that we authorize from time to time. We also may issue debt securities pursuant to the indentures in transactions exempt from the registration requirements of the Securities Act. Those debt securities will not be considered in determining the aggregate amount of securities issued under this prospectus.

Unless otherwise indicated in the applicable prospectus supplement, we will issue the debt securities in denominations of $1,000 or integral multiples of $1,000.

Other than as described below under “The Senior Indentures Limit Our Ability to Incur Liens” and as may be described in the applicable prospectus supplement, the indentures do not limit our ability to incur indebtedness or afford holders of debt securities protection in the event of a decline in our credit quality or if we are involved in a takeover, recapitalization, or highly leveraged or similar transaction. Nothing in the indentures or the debt securities will in any way limit the amount of indebtedness or securities that we or our subsidiaries, as defined in the indentures, may incur or issue.

General

We may issue the debt securities in one or more series, with the same or various maturities, at par or at a discount. We will describe the particular terms of each series of debt securities in a prospectus supplement relating to that series, which we will file with the SEC. The prospectus supplement relating to the particular

12

series of debt securities being offered will specify whether they are senior or subordinated debt securities and the amounts, prices, and terms of those debt securities. These terms may include:

13

We are not obligated to issue all debt securities of any one series at the same time and, unless we specify otherwise in the applicable prospectus supplement, a series of debt securities may be reopened for additional issuances of debt securities of that series or to establish additional terms of that series.

If any of the debt securities are sold for foreign currencies or foreign currency units or if the principal of, or any premium or interest on, any series of debt securities is payable in foreign currencies or foreign currency units, we will describe the restrictions, elections, tax consequences, specific terms, and other information with respect to those debt securities and such foreign currencies or foreign currency units in the applicable prospectus supplement.

The terms, if any, on which the debt securities of any series are convertible into or exchangeable for shares of common stock, shares of preferred stock, or other securities, whether or not issued by us, property, or cash, or a combination of any of the foregoing, will be set out in the accompanying prospectus supplement. Such terms may include provisions for conversion or exchange, either mandatory, at the option of the holder, or at our option, in which the securities, property, or cash to be received by the holders of the debt securities would be calculated according to the factors and at such time as described in the accompanying prospectus supplement.

Ranking

Senior Debt Securities

Unless otherwise indicated in the applicable prospectus supplement, our obligation to pay the principal of, and any premium and interest on, the senior debt securities will be unsecured and will rank equally with all of our other unsecured unsubordinated indebtedness.

Subordinated Debt Securities

Our obligation to pay the principal of, and any premium and interest on, any subordinated debt securities will be unsecured and will rank subordinate and junior in right of payment to all of our senior indebtedness to the extent provided in the subordinated indenture and the terms of those subordinated debt securities, as described below and in any applicable prospectus supplement, which may make deletions from, or modifications or additions to, the subordination terms described below.

Upon any payment or distribution of our assets or securities to creditors upon any liquidation, dissolution, winding-up, reorganization, or any bankruptcy, insolvency, receivership, or similar proceedings in connection with any insolvency or bankruptcy proceeding of APA, the holders of senior indebtedness will first be entitled to receive payment in full of the senior indebtedness before the holders of subordinated debt securities will be entitled to receive any payment or distribution in respect of the subordinated debt securities.

No payments on account of principal or any premium or interest in respect of the subordinated debt securities may be made if there has occurred and is continuing a default in any payment with respect to senior indebtedness or an event of default with respect to any senior indebtedness resulting in the acceleration of its maturity or if any judicial proceeding is pending with respect to any default.

“Indebtedness,” for purposes of the subordinated indenture, means any obligation created or assumed by any person for the repayment of money borrowed, any purchase money obligation created or assumed by such person, and any guarantee of the foregoing.

“Senior indebtedness,” for purposes of the subordinated indenture, means all indebtedness, whether outstanding on the date of execution of the subordinated indenture or thereafter created, assumed, or incurred, except our obligations under the subordinated debt securities, indebtedness ranking equally with the subordinated debt securities, or indebtedness ranking junior to the subordinated debt securities.

“Indebtedness ranking equally with the subordinated debt securities,” for purposes of the subordinated indenture, means indebtedness, whether outstanding on the date of execution of the subordinated indenture or thereafter

14

created, assumed, or incurred, to the extent the indebtedness specifically by its terms ranks equally with and not prior to the subordinated debt securities in the right of payment upon the happening of the dissolution, winding-up, liquidation, or reorganization of APA. The securing of any indebtedness otherwise constituting indebtedness ranking equally with the subordinated debt securities will not prevent the indebtedness from constituting indebtedness ranking equally with the subordinated debt securities.

“Indebtedness ranking junior to the subordinated debt securities,” for purposes of the subordinated indenture, means any indebtedness, whether outstanding on the date of execution of the subordinated indenture or thereafter created, assumed, or incurred, to the extent the indebtedness by its terms ranks junior to and not equally with or prior to:

The securing of any indebtedness otherwise constituting indebtedness ranking junior to the subordinated debt securities will not prevent the indebtedness from constituting indebtedness ranking junior to the subordinated debt securities.

Dividends and other distributions to us from our various subsidiaries may be subject to statutory, contractual, and other restrictions (including, without limitation, exchange controls that may be applicable to foreign subsidiaries). The rights of our creditors to participate in the assets of any subsidiary upon that subsidiary’s liquidation or recapitalization will be subject to the prior claims of the subsidiary’s creditors, except to the extent that we may ourselves be a creditor with recognized claims against the subsidiary.

Interest Rates and Discounts

The debt securities will earn interest at a fixed or floating rate or rates for the period or periods of time specified in the applicable prospectus supplement. Unless we specify otherwise in the applicable prospectus supplement, the debt securities will bear interest on the basis of a 360-day year consisting of twelve 30-day months.

We may sell debt securities at a substantial discount below their stated principal amount, bearing no interest or interest at a rate that at the time of issuance is below market rates. We will describe the federal income tax consequences and the special considerations that apply to any series in the applicable prospectus supplement.

Redemption and Repurchase

The debt securities may be redeemable at our option, or may be subject to mandatory redemption by us, as required by a sinking fund or otherwise. In addition, the debt securities may be subject to repurchase or repayment by us, at the option of the holders. The applicable prospectus supplement will describe the terms, the times, and the prices regarding any optional or mandatory redemption by us or any repurchase or repayment at the option of the holders of any series of debt securities.

Exchange, Registration, and Transfer

Registered securities of any series that are not global securities will be exchangeable for other registered securities of the same series and of like aggregate principal amount and tenor in different authorized denominations. In addition, if debt securities of any series are issuable as both registered securities and bearer securities, the holder may choose, upon written request, and subject to the terms of the applicable indenture, to exchange bearer securities and the appropriate related coupons of that series into registered securities of the same series of any authorized denominations and of like aggregate principal amount and tenor. Bearer securities with attached coupons surrendered in exchange for registered securities between a regular record date or a special

15

record date and the relevant date for interest payment shall be surrendered without the coupon relating to the interest payment date. Interest will not be payable with respect to the registered security issued in exchange for that bearer security. That interest will be payable only to the holder of the coupon when due in accordance with the terms of the indenture. Bearer securities will not be issued in exchange for registered securities.

You may present registered securities for registration of transfer, together with a duly executed form of transfer, at the office of the security registrar or at the office of any transfer agent designated by us for that purpose with respect to any series of debt securities and referred to in the applicable prospectus supplement. This may be done without service charge but upon payment of any taxes and other governmental charges as described in the applicable indenture. The security registrar or the transfer agent will effect the transfer or exchange upon being satisfied with the documents of title and identity of the person making the request. We have appointed the trustee as security registrar for each indenture. If a prospectus supplement refers to any transfer agents initially designated by us with respect to any series of debt securities in addition to the security registrar, we may at any time rescind the designation of any of those transfer agents or approve a change in the location through which any of those transfer agents acts. If, however, debt securities of a series are issuable solely as registered securities, we will be required to maintain a transfer agent in each place of payment for that series, and if debt securities of a series are issuable as bearer securities, we will be required to maintain a transfer agent in a place of payment for that series located outside of the United States in addition to the security registrar. We may at any time designate additional transfer agents with respect to any series of debt securities.

In the event of any redemption, we will not be required to:

Payment and Paying Agents

Unless we specify otherwise in the applicable prospectus supplement, payment of principal of, and any premium and interest on, bearer securities will be payable in accordance with any applicable laws and regulations, at the offices of those paying agents outside the United States that we may designate at various times. We will make interest payments on bearer securities and the attached coupons on any interest payment date only against surrender of the coupon relating to that interest payment date. No payment with respect to any bearer security will be made at any of our offices or agencies in the United States or by check mailed to any U.S. address or by transfer to an account maintained with a bank located in the United States. If, however, but only if, payment in U.S. dollars of the full amount of principal of, and any premium and interest on, bearer securities denominated and payable in U.S. dollars at all offices or agencies outside the United States is illegal or effectively precluded by exchange controls or other similar restrictions, then those payments will be made at the office of our paying agent in Birmingham, Alabama.

Unless we specify otherwise in the applicable prospectus supplement, payment of principal of, and any premium and interest on, registered securities will be made at the office of the paying agent or paying agents that we designate at various times. At our option, however, we may make interest payments by check mailed to the address, as it appears in the security register, of the person entitled to the payments. Unless we specify otherwise in the applicable prospectus supplement, we will make payment of any installment of interest on registered securities to the person in whose name that registered security is registered at the close of business on the regular record date for such interest.

16

Unless we specify otherwise in the applicable prospectus supplement, the corporate trust office of the trustee in Birmingham, Alabama, will be designated:

We will name any paying agents outside the United States and any other paying agents in the United States initially designated by us for the debt securities in the applicable prospectus supplement. We may at any time designate additional paying agents or rescind the designation of any paying agent or approve a change in the office through which any paying agent acts. If, however, debt securities of a series are issuable solely as registered securities, we will be required to maintain a paying agent in each place of payment for that series. If debt securities of a series are issuable as bearer securities, we will be required to maintain:

If, however, the debt securities of that series are listed on the London Stock Exchange, the Luxembourg Stock Exchange, or any other stock exchange located outside the United States, and if the stock exchange requires it, we will maintain a paying agent in London, Luxembourg, or any other required city located outside the United States for those debt securities.

All monies we pay to a paying agent for the payment of principal of, and any premium or interest on, any debt security or coupon that remains unclaimed at the end of two years after becoming due and payable will be repaid to us. After that time, the holder of the debt security or coupon will look only to us for payments out of those repaid amounts.

Global Securities

The debt securities of a series may be issued in whole or in part in the form of one or more global certificates that we will deposit with a depository identified in the applicable prospectus supplement. Global securities may be issued in either registered or bearer form and in either temporary or permanent form. Unless and until it is exchanged in whole or in part for the individual debt securities it represents, a global security may not be transferred except as a whole:

To the extent not described below, we will describe the terms of the depository arrangement with respect to a series of debt securities in the applicable prospectus supplement. We anticipate that the following provisions will generally apply to depository arrangements.

As long as the depository for a global security, or its nominee, is the registered owner of that global security, the depository or nominee will be considered the sole owner or holder of the debt securities represented by the global

17

security for all purposes under the applicable indenture. Except as provided in any applicable prospectus supplement, owners of beneficial interests in a global security:

The laws of some states require that some purchasers of securities take physical delivery of securities in definitive form. These laws may impair your ability to transfer beneficial interests in a global security.

Payments of principal of, and any premium and interest on, individual debt securities represented by a global security registered in the name of a depository or its nominee will be made to the depository or its nominee as the registered owner of the global security representing such debt securities. Neither we, the trustee, any paying agent, nor the registrar for the debt securities will be responsible for any aspect of the records relating to or payments made by the depository or any participants on account of beneficial interests of the global security.

The Senior Indentures Limit Our Ability to Incur Liens

Unless we specify otherwise in the applicable prospectus supplement, each senior indenture provides that neither APA nor any of its subsidiaries may issue, assume, or guarantee any notes, bonds, debentures, or other similar evidences of indebtedness for money borrowed that are secured by a mortgage, lien, pledge, security interest, or other encumbrance—defined in each senior indenture as “liens”—upon any of its principal property without providing that any and all senior debt securities then or thereafter outstanding shall be secured by a lien equally and ratably with any and all other obligations by the lien. Under each senior indenture, principal property is a property interest in any (i) oil, gas, or other liquid or gaseous hydrocarbon or (ii) natural gas, natural gas liquid, or crude oil pipeline, distribution system, gathering system, storage facility, or processing plant, and in either case, owned by us or our subsidiaries, located in the United States or offshore the United States, and the gross book value (without deduction of any depreciation or depletion reserves) of which exceeds 5% of our consolidated net tangible assets (as defined in each senior indenture), other than any such property that our board of directors declares is not material to the business of us and our subsidiaries as an entirety.

The restrictions on liens will not, however, apply to:

18

Notwithstanding the limitations on liens described above, we and any one or more of our subsidiaries may issue, assume, or guarantee, without regard to the limitations described above, indebtedness secured by liens on assets in any aggregate principal amount which, together with the aggregate outstanding principal amount of all our other indebtedness and indebtedness of any of our subsidiaries so secured (excluding indebtedness secured by the permitted liens described above), does not at the time such indebtedness is incurred exceed 15% of our consolidated net tangible assets.

In addition, the following types of transactions, among others, shall not be deemed to create indebtedness secured by liens:

Each Indenture Includes Events of Default

Unless otherwise specified in the applicable prospectus supplement, any one of the following events will constitute an “event of default” under each indenture with respect to the debt securities of any series issued under that indenture:

No event of default with respect to any particular series of debt securities necessarily constitutes an event of default with respect to any other series of debt securities.

If an event of default with respect to the debt securities of any series, other than an event of default described in the item above pertaining to events of bankruptcy, insolvency, or reorganization, occurs and is continuing, either

19

the trustee or the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series may declare the principal amount of the debt securities of that series to be due and payable immediately. At any time after a declaration of acceleration has been made, but before a judgment or decree for payment of money due has been obtained by the trustee, and subject to applicable law and other provisions of the applicable indenture, the holders of a majority in aggregate principal amount of the debt securities of that series may, under some circumstances, rescind and annul such acceleration. If an event of default occurs pertaining to events of bankruptcy, insolvency, or reorganization, the principal amount and accrued interest—or a lesser amount as provided for in the debt securities of that series—shall be immediately due and payable without any declaration or other act by the trustee or any holder.

Within 90 days after the occurrence of any default under an indenture with respect to the debt securities of any series issued under that indenture, the trustee must transmit notice of the default of which it is aware to the holders of the debt securities of that series unless the default has been cured or waived. The trustee may withhold the notice, however, except in the case of a payment default, if and so long as the board of directors, the executive committee, or a trust committee of directors or responsible officers of the trustee has in good faith determined that the withholding of the notice is in the interest of the holders of debt securities of that series.

If an event of default occurs and is continuing with respect to the debt securities of any series, the trustee may in its discretion proceed to protect and enforce its rights and the rights of the holders of debt securities of that series by all appropriate judicial proceedings.

Subject to the duty of the trustee during any default to act with the required standard of care, the trustee is under no obligation to exercise any of its rights or powers under an indenture at the request or direction of any of the holders of debt securities issued under that indenture, unless the holders offer the trustee indemnity reasonably satisfactory to it. Subject to indemnifying the trustee, and subject to applicable law and other provisions of each indenture, the holders of a majority in aggregate principal amount of the outstanding debt securities of a series issued under that indenture may direct the time, method, and place of conducting any proceeding for any remedy available to the trustee, or exercising any trust or power conferred on the trustee, with respect to the debt securities of that series.

Discharge, Defeasance, and Covenant Defeasance

We may discharge our obligations to holders of any series of debt securities that have not already been delivered to the trustee for cancellation and that:

To discharge the obligations with respect to a series of debt securities, we must deposit with the trustee, in trust, an amount of funds in U.S. dollars or in the foreign currency in which those debt securities are payable, in government obligations, as defined below, applicable to those debt securities, or a combination thereof, sufficient to pay the entire amount of principal of, and any premium or interest on, those debt securities to the date of the deposit if those debt securities have become due and payable or to the maturity of the debt securities, as the case may be.

Unless we specify otherwise in the applicable prospectus supplement, we may elect:

20

In the case of discharge of our obligations or legal defeasance we will still retain some obligations in respect of the debt securities, including our obligations:

After a covenant defeasance, any omission to comply with the obligations or covenants that have been defeased shall not constitute a default or an event of default with respect to the debt securities.

To elect either legal defeasance or covenant defeasance, we must deposit with the trustee, in trust, an amount, in U.S. dollars or in the foreign currency in which the relevant debt securities are payable at stated maturity, or in government obligations, as defined below, or both, applicable to such debt securities which through the scheduled payment of principal and interest in accordance with their terms will provide money in an amount sufficient to pay the principal of and any premium and interest on those debt securities on their scheduled due dates.

In addition, we can only elect legal defeasance or covenant defeasance if, among other things:

Each of the indentures deems a foreign currency to be any currency, currency unit, or composite currency issued by the government of one or more countries other than the United States or by any recognized confederation or association of governments.

Each of the indentures defines government obligations as securities which are not callable or redeemable at the option of the issuer or issuers and are:

21

Government obligations also include a depositary receipt issued by a bank or trust company as custodian with respect to any government obligation described above or a specific payment of interest on or principal of or any other amount with respect to any government obligation held by that custodian for the account of the holder of such depositary receipt, as long as, except as required by law, that custodian is not authorized to make any deduction from the amount payable to the holder of the depositary receipt from any amount received by the custodian with respect to the government obligation or the specific payment of interest on or principal of or any other amount with respect to the government obligation evidenced by the depositary receipt.

Unless otherwise specified in the applicable prospectus supplement, if, after we have deposited funds and/or government obligations to effect legal defeasance or covenant defeasance with respect to debt securities of any series, the holder of a debt security of that series is entitled to, and does, elect to receive payment in a currency other than that in which such deposit has been made in respect of that debt security, the indebtedness represented by that debt security shall be deemed to have been, and will be, fully discharged and satisfied through the payment of the principal of, and any premium and interest on, that debt security as that debt security becomes due out of the proceeds yielded by converting the amount or other properties so deposited in respect of that debt security into the currency in which that debt security becomes payable as a result of the election based on the applicable market exchange rate for the currency in effect on the second business day prior to the date of the payment.

Unless otherwise provided in the applicable prospectus supplement, all payments of principal of, and any premium and interest on, any debt securities that are payable in a foreign currency that ceases to be used by the government or confederation of issuance shall be made in U.S. dollars.

If we effect a covenant defeasance with respect to any debt securities and the debt securities are declared due and payable because of the occurrence of any event of default other than an event of default with respect to which there has been covenant defeasance, the amount in the foreign currency in which the debt securities are payable, and government obligations on deposit with the trustee, will be sufficient to pay amounts due on the debt securities at the time of the stated maturity but may not be sufficient to pay amounts due on the debt securities at the time of the acceleration resulting from the event of default. We would remain liable, however, for payment of the amounts due at the time of acceleration.

The applicable prospectus supplement may further describe the provisions, if any, permitting defeasance or covenant defeasance, including any modifications to the provisions described above, with respect to the debt securities of or within a particular series.

Under each indenture, we are required to furnish to the trustee annually a statement as to our performance of our obligations under the indenture and as to any default in such performance. We are also required to deliver to the trustee, within five days after occurrence thereof, written notice of any event of default or event that after notice or lapse of time or both would constitute an event of default.

Modification and Waiver

We and the trustee may, without the consent of holders, modify provisions of each indenture for specified purposes, including, among other things, curing ambiguities and maintaining the qualification of the applicable indenture under the Trust Indenture Act. We and the trustee may modify other provisions of each indenture with the consent of the holders of a majority in aggregate principal amount of the debt securities of each series issued

22

under that indenture affected by the modification, except that the provisions of the indentures, however, may not be modified without the consent of the holder of each debt security affected thereby if the modification would:

The holders of at least a majority in aggregate principal amount of debt securities of any series issued under one of the indentures may, on behalf of the holders of all debt securities of that series, waive our compliance with specified restrictive provisions of that indenture. The holders of not less than a majority in aggregate principal amount of debt securities of any series issued under one of the indentures may, on behalf of all holders of debt securities of that series, waive any past default and its consequences under that indenture with respect to the debt securities of that series, except:

Consolidation, Merger, and Sale of Assets

We may, without the consent of the holders of the debt securities, consolidate or merge with or into, or convey, transfer, or lease our properties and assets as an entirety or substantially as an entirety to, any person that is a corporation or limited liability company organized and validly existing under the laws of the United States of America, any state thereof, or the District of Columbia. We may also permit any of those persons to consolidate with or merge into us or convey, transfer, or lease its properties and assets substantially as an entirety to us, as long as:

23

Governing Law

The indentures and the debt securities will be governed by, and construed in accordance with, the laws of the State of New York.

24

DESCRIPTION OF PURCHASE CONTRACTS AND UNITS

We may issue stock purchase contracts, representing contracts entitling or obligating holders to purchase from or sell to us, and us to sell to or purchase from the holders, a specified number of shares of common stock at a future date or dates. The price per share of common stock may be fixed at the time the contracts are issued or may be determined by reference to a specific formula set forth in the contracts. The common stock purchase contracts may be issued separately or as a part of units, which are referred to in this prospectus as “common stock purchase units,” consisting of a common stock purchase contract and, as security for the holder’s obligations to purchase the common stock under the contracts, the following:

The common stock purchase contracts may require us to make periodic payments to the holders of the common stock purchase units or vice versa, which payments may be unsecured or prefunded on some basis. Such payments may also be deferred to the extent set forth in the applicable prospectus supplement. The common stock purchase contracts may require holders thereof to secure their obligations thereunder in a specified manner to be described in the applicable prospectus supplement, and in some circumstances, we may deliver newly issued prepaid common stock purchase contracts, which are referred to as “prepaid securities,” upon release to a holder of any collateral securing such holder’s obligations under the original contract. The common stock purchase contracts may require holders to satisfy their obligations thereunder when the purchase contracts are issued or at settlement. Our obligation to settle any prepaid securities on the relevant settlement date may constitute indebtedness.

The applicable prospectus supplement will describe the terms of any common stock purchase contracts or units and, if applicable, prepaid securities. The description in the prospectus supplement will not purport to be complete and will be qualified in its entirety by reference to the contracts, the collateral arrangements, and depositary arrangements, if applicable, relating to such contracts or units and, if applicable, the prepaid securities and the document pursuant to which such prepaid securities will be issued.

25

DESCRIPTION OF WARRANTS

We may issue warrants to purchase shares of common stock or preferred stock from time to time. Each series of warrants will be issued under a separate warrant agreement to be entered into between us and a bank or trust company, to be selected at the time of issue, as warrant agent. Warrants may be issued independently or together with any other securities and may be attached to, or separate from, such securities. The applicable prospectus supplement will include a description of the material provisions of the applicable warrant agreement and will describe the designation and terms of the warrants to be issued, including, without limitation, the following:

The foregoing statements with respect to the warrants are summaries of, and subject to, the detailed provisions of the applicable warrant agreement.

Holders of warrants will not be entitled, by virtue of being such holders, to vote, to consent, to receive dividends, to receive notice as stockholders with respect to any meeting of stockholders for the election of our directors or any other matter, or to exercise any rights whatsoever as our stockholders.

26

PLAN OF DISTRIBUTION

We may sell offered securities in any one or more of the following ways from time to time:

The prospectus supplement with respect to the offered securities will set forth the terms of the offering of the offered securities, including:

We may sell offered securities directly to institutional investors or others who may be deemed to be underwriters within the meaning of the Securities Act. Direct sales may be arranged by one or more securities broker-dealers or other financial intermediaries.

Any initial public offering price, discounts, or concessions allowed or re-allowed or paid to dealers may be changed from time to time.

The distribution of the offered securities may be effected from time to time in one or more transactions at a fixed price or prices, which may vary or be changed, at market prices prevailing at the time of sale, at prices related to such prevailing market prices, or at negotiated prices.

Offered securities may be sold directly by us or through agents designated by us from time to time. Any agent involved in the offer or sale of the offered securities in respect of which this prospectus is delivered will be named, and any commissions payable by us to such agent will be set forth, in the applicable prospectus supplement. Unless otherwise indicated in such prospectus supplement, any such agent will be acting on a reasonable best efforts basis for the period of its appointment. Any such agent may be deemed to be an underwriter, as that term is defined in the Securities Act, of the offered securities so offered and sold.

If offered securities are sold by means of an underwritten offering, we will execute an underwriting agreement with an underwriter or underwriters, and the names of the specific managing underwriter or underwriters, as well as any other underwriters, and the terms of the transaction, including commissions, discounts, and any other compensation of the underwriters and dealers, if any, will be set forth in the prospectus supplement, which will be used by the underwriters in connection with sales of the offered securities. The offered securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including negotiated transactions, at fixed public offering prices or at varying prices determined by the underwriters at the time of sale.

27

Our offered securities may be offered to the public either through underwriting syndicates represented by managing underwriters or directly by the managing underwriters. Unless otherwise indicated in the prospectus supplement, the underwriting agreement will provide that the obligations of the underwriters are subject to certain conditions precedent. The underwriters will be obligated to purchase all of the offered securities of a series if they purchase any of such offered securities.

We may grant to the underwriters options to purchase additional offered securities, to cover over-allotments, if any, at the public offering price (with additional underwriting discounts or commissions), as may be set forth in the prospectus supplement relating thereto. If we grant any over-allotment option, the terms of such over-allotment option will be set forth in the prospectus supplement relating to such offered securities.

Underwriters, dealers, and agents participating in a sale of offered securities may be deemed to be underwriters as defined in the Securities Act, and any discounts and commissions received by them and any profit realized by them on resale of offered securities may be deemed to be underwriting discounts and commissions under the Securities Act. We may have agreements with underwriters, dealers, and agents to indemnify them against certain civil liabilities, including liabilities under the Securities Act, and to reimburse them for certain expenses.

Offered securities may also be sold to or through one or more underwriters or agents in at-the-market offerings, pursuant to the terms of a distribution agreement between us and the underwriters or agents. If we engage in at-the-market sales pursuant to a distribution agreement, we will issue and sell shares of our common stock to or through one or more underwriters or agents, which may act on an agency basis or on a principal basis. During the term of any such agreement, we may sell shares on a daily basis in exchange transactions or otherwise as we may agree with the underwriters or agents. The distribution agreement will provide that any shares of our common stock sold will be sold at prices related to the then-prevailing market prices for our common stock. Pursuant to the terms of a distribution agreement, we also may agree to sell, and the relevant underwriters or agents may agree to solicit offers to purchase, blocks of our common stock or other securities. The terms of each such distribution agreement will be set forth in more detail in a prospectus supplement to this prospectus.

In connection with an offering, the underwriters or other agents may purchase and sell securities in the open market. These transactions may include short sales, stabilizing transactions, and purchases to cover positions created by short sales. Short sales involve the sale by an agent of a greater number of securities than they are required to purchase in an offering. Stabilizing transactions consist of certain bids or purchases made for the purpose of preventing or retarding a decline in the market price of the securities while an offering is in progress.

The agents may also impose a penalty bid. This occurs when a particular agent repays to the agents a portion of the discount received by it because the agents have repurchased securities sold by or for the account of that agent in stabilizing or short-covering transactions.

These activities by the agents may stabilize, maintain, or otherwise affect the market price of the securities. As a result, the price of the securities may be higher than the price that otherwise might exist in the open market. The agents are not required to engage in any of these activities and, if such activities are commenced, they may be discontinued by the agents at any time. These transactions may be effected on an exchange or automated quotation system, if the securities are listed on that exchange or admitted for trading on that automated quotation system, or in the over-the-counter market or otherwise.

If a dealer is utilized in the sales of offered securities, we will sell such offered securities to the dealer as principal. The dealer may then resell such offered securities to the public at varying prices to be determined by such dealer at the time of resale. Any such dealer may be deemed to be an underwriter, as such term is defined in the Securities Act, of the offered securities so offered and sold. The name of the dealer and the terms of the transaction will be set forth in the related prospectus supplement.

We may enter into derivative transactions with third parties or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection

28

with those derivatives, such third parties (or affiliates of such third parties) may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, such third parties (or affiliates of such third parties) may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of stock and may use securities received from us in settlement of those derivatives to close out any related open borrowings of stock. The third parties (or affiliates of such third parties) in such sale transactions will be underwriters and, if not identified in this prospectus, will be identified in the applicable prospectus supplement (or a post-effective amendment).

We may loan or pledge securities to a financial institution or other third party that in turn may sell the securities using this prospectus. Such financial institution or third party may transfer its short position to investors in our securities or in connection with a simultaneous offering of other securities offered by this prospectus.

Offered securities may also be offered and sold, if so indicated in the applicable prospectus supplement, in connection with a remarketing upon their purchase, in accordance with a redemption or repayment pursuant to their terms, or otherwise, by one or more firms (“remarketing firms”), acting as principals for their own accounts or as agents for us. Any remarketing firm will be identified, and the terms of its agreements with us and its compensation will be described, in the applicable prospectus supplement. Remarketing firms may be deemed to be underwriters, as such term is defined in the Securities Act, in connection with the offered securities remarketed thereby.

Agents, underwriters, dealers, and remarketing firms may be entitled under relevant agreements entered into with us to indemnification by us against certain civil liabilities, including liabilities under the Securities Act that may arise from any untrue statement or alleged untrue statement of a material fact or any omission or alleged omission to state a material fact in this prospectus, any supplement or amendment hereto, or in the registration statement of which this prospectus forms a part, or to contribution with respect to payments which the agents, underwriters, or dealers may be required to make.

We may authorize underwriters or other persons acting as agents to solicit offers by certain institutions to purchase offered securities from us pursuant to contracts providing for payments and delivery on a future date. Institutions with which such contracts may be made include commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions, and others, but in all cases such institutions must be approved by us. The obligations of any purchaser under any such contract will be subject to the condition that the purchase of the offered securities shall not at the time of delivery be prohibited under the laws of the jurisdiction to which such purchaser is subject. The underwriters and such other agents will not have any responsibility in respect of the validity or performance of such contracts.

Disclosure in the prospectus supplement of the use by us of delayed delivery contracts will include the commission that underwriters and agents soliciting purchases of the securities under delayed contracts will be entitled to receive, in addition to the date when we will demand payment and delivery of the securities under the delayed delivery contracts. These delayed delivery contracts will be subject only to the conditions that are described in the prospectus supplement.

Underwriters, dealers, agents, and remarketing firms may be customers of, engage in transactions with, or perform services for us in the ordinary course of business.

Other than our common stock, and unless otherwise specified in the applicable prospectus supplement, each class or series of securities offered by this prospectus and the applicable prospectus supplement will be a new issue of securities with no established trading market. The securities may or may not be listed on a national securities exchange or a foreign securities exchange, except for the common stock that is currently listed and traded on the Nasdaq Global Select Market. We cannot give you any assurance as to the liquidity of or the trading markets for any securities.

29

Under Rule 15c6-1 under the Exchange Act (as amended in February 2023), trades in the secondary market will generally be required to settle in one business day, unless the parties to such trade expressly agree otherwise. Accordingly, if the settlement date specified on the cover page of the applicable prospectus supplement is later than the first business day following the trade date, then any purchaser who wishes to trade the securities prior to the settlement date, will be required, by virtue of the fact that the sale of the securities initially will settle on such later business day, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Any purchaser who wishes to trade the securities prior to the settlement date specified on the cover page of the applicable prospectus supplement should consult their own advisor in connection with such election.

VALIDITY OF THE SECURITIES

The validity of the securities will be passed upon for us by Bracewell LLP, Houston, Texas. If the securities are being distributed through underwriters or agents, the validity of the securities will be passed upon for the underwriters or agents by counsel identified in the related prospectus supplement.

Item 14. Other Expenses of Issuance and Distribution.

The following sets forth the expenses in connection with the issuance and distribution of the securities being registered hereby, other than underwriting discounts and commissions. All amounts set forth below, other than the SEC registration fee, are estimates.

Item 15. Indemnification of Directors and Officers.

APA CORPORATION

APA’s amended and restated certificate of incorporation, as amended, and amended and restated bylaws provide that, to the fullest extent permitted under the Delaware General Corporation Law, APA’s directors shall not be personally liable for monetary damages. APA’s amended and restated bylaws provide that APA shall indemnify its officers, directors, employees, and agents.

Section 145 of the Delaware General Corporation Law, inter alia, authorizes a corporation to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending, or completed action, suit, or proceeding, other than an action by or in the right of the corporation, because such person is or was a director, officer, employee, or agent of the corporation or was serving at the request of the corporation as a director, officer, employee, or agent of another corporation or other enterprise, against expenses, including attorneys’ fees, judgments, fines, and amounts paid in settlement actually and reasonably incurred by such person in connection with such suit or proceeding if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reason to believe such person’s conduct was unlawful. Similar indemnity is authorized for such persons against expenses, including attorneys’ fees, actually and reasonably incurred in defense or settlement of any such pending, completed, or threatened action or suit by or in the right of the corporation if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the corporation, and provided further that, unless a court of competent jurisdiction otherwise provides, such person shall not have been adjudged liable to the corporation. Any such indemnification may be made only as authorized in each specific case upon a determination by the stockholders or disinterested directors that indemnification is proper because the indemnitee has met the applicable standard of conduct.

Section 145 of the Delaware General Corporation Law further authorizes a corporation to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee, or agent of the corporation, or is or

II-1

was serving at the request of the corporation as a director, officer, employee, or agent of another corporation or enterprise, against any liability asserted against such person and incurred by such person in any such capacity, or arising out of such person’s status as such, whether or not the corporation would otherwise have the power to indemnify such person. APA maintains policies insuring its and its subsidiaries’ officers and directors against specified liabilities for actions taken in such capacities, including liabilities under the Securities Act.

Article VII of APA’s amended and restated bylaws provides, in substance, that directors, officers, employees, and agents of APA shall be indemnified to the fullest extent permitted by the Delaware General Corporation Law. Additionally, Article Seventeenth of APA’s amended and restated certificate of incorporation, as amended, eliminates in specified circumstances the monetary liability of directors and officers of APA for a breach of their fiduciary duty as directors or officers, as applicable. These provisions do not eliminate the liability of a director or officer:

Section 103. Form of Documents Delivered to Trustee.

Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Indenture or any Security, they may, but need not, be consolidated and form one instrument.

Section 104. Acts of Holders.

(i) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by or pursuant to this Indenture to be given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by an agent duly appointed in writing. If, but only if, Securities of a series are issuable as Bearer Securities, any request, demand, authorization, direction, notice, consent, waiver or other action provided in or pursuant to this Indenture to be given or taken by Holders of Securities of such series may, alternatively, be embodied in and evidenced by the record of Holders of Securities of such series voting in favor thereof, either in person or by proxies duly appointed in writing, at any meeting of Holders of Securities of such series duly called and held in accordance with the provisions of Article Fourteen, or a combination of such instruments and any such record. Except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments or record or both are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments and any such record (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments or so voting at any such meeting. Proof of execution of any such instrument or of a writing appointing any such agent, or of the holding by any Person of a Security, shall be sufficient for any purpose of this Indenture and (subject to Section 315 of the Trust Indenture Act) conclusive in favor of the Trustee and the Company and any agent of the Trustee or the Company, if made in the manner provided in this Section. The record of any meeting of Holders of Securities shall be proved in the manner provided in Section 1406.

Without limiting the generality of this Section 104, unless otherwise provided in or pursuant to this Indenture, a Holder, including a U.S. Depository that is a Holder of a global Security, may make, give or take, by a proxy, or proxies, duly appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or other Act provided in or pursuant to this Indenture to be made, given or taken by Holders, and a U.S. Depository that is a Holder of a global Security may provide its proxy or proxies to the beneficial owners of interests in any such global Security through such U.S. Depository’s standing instructions and customary practices.

-10-

The Trustee shall fix a record date for the purpose of determining the Persons who are beneficial owners of interest in any permanent global Security held by a U.S. Depository entitled under the procedures of such U.S. Depository to make, give or take, by a proxy or proxies duly appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or other Act provided in or pursuant to this Indenture to be made, given or taken by Holders. If such a record date is fixed, the Holders on such record date or their duly appointed proxy or proxies, and only such Persons, shall be entitled to make, give or take such request, demand, authorization, direction, notice, consent, waiver or other Act, whether or not such Holders remain Holders after such record date. No such request, demand, authorization, direction, notice, consent, waiver or other Act shall be valid or effective if made, given or taken more than 90 days after such record date.

(ii) The fact and date of the execution by any Person of any such instrument or writing may be proved in any reasonable manner which the Trustee deems sufficient and in accordance with such reasonable rules as the Trustee may determine; and the Trustee may in any instance require further proof with respect to any of the matters referred to in this Section.

(iii) The ownership, principal amount and serial numbers of Registered Securities held by any Person, and the date of the commencement and the date of the termination of holding the same, shall be proved by the Security Register.

(iv) The ownership, principal amount and serial numbers of Bearer Securities held by any Person, and the date of the commencement and the date of the termination of holding the same, may be proved by the production of such Bearer Securities or by a certificate executed, as depositary, by any trust company, bank, banker or other depositary reasonably acceptable to the Company, wherever situated, if such certificate shall be deemed by the Company and the Trustee to be satisfactory, showing that at the date therein mentioned such Person had on deposit with such depositary, or exhibited to it, the Bearer Securities therein described; or such facts may be proved by the certificate or affidavit of the Person holding such Bearer Securities, if such certificate or affidavit is deemed by the Trustee to be satisfactory. The Trustee and the Company may assume that such ownership of any Bearer Security continues until (1) another certificate or affidavit bearing a later date issued in respect of the same Bearer Security is produced, or (2) such Bearer Security is produced to the Trustee by some other Person, or (3) such Bearer Security is surrendered in exchange for a Registered Security, or (4) such Bearer Security is no longer Outstanding. The ownership, principal amount and serial numbers of Bearer Securities held by the Person so executing such instrument or writing and the date of the commencement and the date of the termination of holding the same may also be proved in any other manner which the Company and the Trustee deem sufficient.

-11-

(v) If the Company shall solicit from the Holders of any Registered Securities any request, demand, authorization, direction, notice, consent, waiver or other Act, the Company may at its option (but is not obligated to), by Board Resolution, fix in advance a record date for the determination of Holders of Registered Securities entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after such record date, but only the Holders of Registered Securities of record at the close of business on such record date shall be deemed to be Holders for the purpose of determining whether Holders of the requisite proportion of Outstanding Securities have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the Outstanding Securities shall be computed as of such record date; provided that no such authorization, agreement or consent by the Holders of Registered Securities shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than six months after the record date.

(vi) Any request, demand, authorization, direction, notice, consent, waiver or other Act by the Holder of any Security shall bind every future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done or suffered to be done by the Trustee, any Security Registrar, any Paying Agent or the Company in reliance thereon, whether or not notation of such Act is made upon such Security.

Section 105. Notices, etc. to Trustee and Company.

Any request, demand, authorization, direction, notice, consent, waiver or other Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with,

Section 106. Notice to Holders of Securities; Waiver.

Except as otherwise expressly provided in or pursuant to this Indenture, where this Indenture provides for notice to Holders of Securities of any event,

-12-

In any case where notice to Holders of Registered Securities is sent pursuant to the terms hereof, neither the failure to send such notice, nor any defect in any notice so sent, to any particular Holder of a Registered Security shall affect the sufficiency of such notice with respect to other Holders of Registered Securities or the sufficiency of any notice to Holders of Bearer Securities given as provided herein. Any notice which is sent in the manner herein provided shall be conclusively presumed to have been duly given or provided. In the case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail or otherwise send it pursuant to the terms hereof, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder.

In case by reason of the suspension of publication of any Authorized Newspaper or Authorized Newspapers or by reason of any other cause it shall be impracticable to publish any notice to Holders of Bearer Securities as provided above, then such notification to Holders of Bearer Securities as shall be given with the approval of the Trustee shall constitute sufficient notice to such Holders for every purpose hereunder. Neither failure to give notice by publication to Holders of Bearer Securities as provided above, nor any defect in any notice so published, shall affect the sufficiency of any notice sent to Holders of Registered Securities as provided above.

Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders of Securities shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

Section 107. Language of Notices.

Any request, demand, authorization, direction, notice, consent, election or waiver required or permitted under this Indenture shall be in the English language, except that, if the Company so elects, any published notice may be in an official language of the country of publication.

Section 108. Conflict with Trust Indenture Act.

If any provision hereof limits, qualifies or conflicts with any duties under any required provision of the Trust Indenture Act imposed hereon by Section 318(c) thereof, such required provision shall control.

-13-

Section 109. Effect of Headings and Table of Contents; Interpretation.

The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof.

The serial comma is sometimes included and sometimes omitted. Its inclusion or omission shall not affect the interpretation of any phrase.

All covenants and agreements in this Indenture by the Company shall bind its successors and assigns, whether so expressed or not.

Section 111. Separability Clause.

In case any provision in this Indenture, any Security or any Coupon shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

Section 112. Benefits of Indenture.

Nothing in this Indenture, any Security or any Coupon, express or implied, shall give to any Person, other than the parties hereto, any Security Registrar, any Paying Agent and their successors hereunder and the Holders of Securities or Coupons, any benefit or any legal or equitable right, remedy or claim under this Indenture.

Section 113. Governing Law.

This Indenture, the Securities and any Coupons shall be governed by and construed in accordance with the laws of the State of New York applicable to agreements made or instruments entered into and, in each case, performed in said state without regard to the conflict of laws principles thereof.

Section 114. Legal Holidays.

Unless otherwise specified in or pursuant to this Indenture or any Securities, in any case where any Interest Payment Date or Maturity of any Security shall be a Legal Holiday at any Place of Payment, then (notwithstanding any other provision of this Indenture, any Security or any Coupon other than a provision in any Security or Coupon that specifically states that such provision shall apply in lieu hereof) payment need not be made at such Place of Payment on such date, and no interest shall accrue on the amount payable on such date or at such time for the period from and after such Interest Payment Date or Maturity, as the case may be, to the next succeeding Business Day.

Section 115. Counterparts.

This Indenture may be executed in several counterparts, each of which shall be an original and all of which shall constitute but one and the same instrument. The exchange of copies of this Indenture and of signature pages by facsimile or PDF transmission shall constitute effective execution and delivery of this Indenture as to the parties hereto and may be used in lieu of the original Indenture for all purposes. Signatures of the parties hereto transmitted by facsimile or PDF shall be deemed to be their original signatures for all purposes.

Section 116. Judgment Currency.

The Company agrees, to the fullest extent that it may effectively do so under applicable law, that (a) if for the purpose of obtaining judgment in any court it is necessary to convert the sum due in respect of the principal of, or premium or interest, if any, on the Securities of any series (the “Required Currency”) into a currency in which a judgment will be rendered (the “Judgment Currency”), the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Trustee could purchase in The City of New York the Required Currency with the Judgment Currency on the New York Banking Day preceding that on which a final unappealable judgment is given and (b) the Company’s obligations under this Indenture to make payments in the Required Currency (i) shall not be discharged or satisfied by any tender, or any recovery pursuant to any judgment (whether or not entered in accordance with clause (a)), in any currency other than the Required Currency, except to the extent that such tender or recovery shall result in the actual receipt, by the payee, of the full amount of the Required Currency expressed to be payable in respect of such payments, (ii) shall be enforceable as an alternative or additional cause of action for the purpose of recovering in the Required Currency the amount, if any, by which such actual receipt shall fall short of the full amount of the Required Currency so expressed to be payable and (iii) shall not be affected by judgment being obtained for any other sum due under this Indenture. For purposes of the foregoing, “New York Banking Day” means any day except a Saturday, Sunday or a legal holiday in The City of New York or a day on which banking institutions in The City of New York are authorized or obligated by law, regulation or executive order to be closed.

With respect to any Securities to be authenticated and delivered hereunder, there shall be established in or pursuant to a Board Resolution, an Officers’ Certificate or established in one or more indentures supplemental hereto,

-17-

-18-

-19-

All Securities of any one series and all Coupons, if any, appertaining to Bearer Securities of such series shall be substantially identical except as to Currency of payments due thereunder, denomination and the rate of interest, or method of determining the rate of interest, if any, Maturity, and the date from which interest, if any, shall accrue and except as may otherwise be provided by the Company in or pursuant to the Board Resolution and set forth in the Officers’ Certificate or in any indenture or indentures supplemental hereto pertaining to such series of Securities. The terms of the Securities of any series may provide, without limitation, that the Securities shall be authenticated and delivered by the Trustee on original issue from time to time upon telephonic or written order of persons designated in the Officers’ Certificate or supplemental indenture (telephonic instructions to be promptly confirmed in writing by such person) and that such persons are authorized to determine, consistent with such Officers’ Certificate or any applicable supplemental indenture, such terms and conditions of the Securities of such series as are specified in such Officers’ Certificate or supplemental indenture. All Securities of any one series need not be issued at the same time and, unless otherwise so provided by the Company, a series may be reopened for issuances of additional Securities of such series or to establish additional terms of such series of Securities.

If any of the terms of the Securities of any series shall be established by action taken by or pursuant to a Board Resolution, the Board Resolution shall be delivered to the Trustee at or prior to the delivery of the Officers’ Certificate setting forth the terms of such series.

Section 302. Currency; Denominations.

Unless otherwise provided in or pursuant to this Indenture, the principal of, and any premium and interest on, the Securities shall be payable in Dollars. Unless otherwise provided in or pursuant to this Indenture, Registered Securities denominated in Dollars shall be issuable in registered form without Coupons in denominations of $1,000 and any integral multiple thereof, and the Bearer Securities denominated in Dollars shall be issuable in the denomination of $5,000. Securities not denominated in Dollars shall be issuable in such denominations as are established with respect to such Securities in or pursuant to this Indenture.

Section 303. Execution, Authentication, Delivery and Dating.

Securities shall be executed on behalf of the Company by its Chairman of the Board, one of its Vice Chairmen, its President, its Treasurer or one of its Vice Presidents and attested by its Secretary or one of its Assistant Secretaries. Coupons shall be executed on behalf of the Company by the Treasurer, one of its Vice Presidents or any Assistant Treasurer of the Company. The signature of any of these officers on the Securities or any Coupons appertaining thereto may be manual or facsimile.

Securities and any Coupons appertaining thereto bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of such Securities or Coupons.

-20-

At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities, together with any Coupons appertaining thereto, executed by the Company, to the Trustee for authentication and, provided that the Board Resolution and Officers’ Certificate or supplemental indenture or indentures with respect to such Securities referred to in Section 301 and a Company Order for the authentication and delivery of such Securities have been delivered to the Trustee, the Trustee in accordance with the Company Order and subject to the provisions hereof and of such Securities shall authenticate and deliver such Securities. In authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities and any Coupons appertaining thereto, the Trustee shall be entitled to receive, and (subject to Sections 315(a) through 315(d) of the Trust Indenture Act) shall be fully protected in relying upon,

-21-

If all the Securities of any series are not to be issued at one time, it shall not be necessary to deliver an Opinion of Counsel and an Officers’ Certificate at the time of issuance of each Security, but such opinion and certificate, with appropriate modifications, shall be delivered at or before the time of issuance of the first Security of such series. After any such first delivery, any separate request by the Company that the Trustee authenticate Securities of such series for original issue will be deemed to be a certification by the Company that all conditions precedent provided for in this Indenture relating to authentication and delivery of such Securities continue to have been complied with.

The Trustee shall not be required to authenticate or to cause an Authenticating Agent to authenticate any Securities if the issue of such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee or if the Trustee, being advised by counsel, determines that such action may not lawfully be taken.

Each Registered Security shall be dated the date of its authentication. Each Bearer Security and any Bearer Security in global form shall be dated as of the date specified in or pursuant to this Indenture.

No Security or Coupon appertaining thereto shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose, unless there appears on such Security a certificate of authentication substantially in the form provided for in Section 202 or 611 executed by or on behalf of the Trustee or by the Authenticating Agent by the manual signature of one of its authorized officers. Such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. Except as permitted by Section 306 or 307, the Trustee shall not authenticate and deliver any Bearer Security unless all Coupons appertaining thereto then matured have been detached and cancelled.

Section 304. Temporary Securities.

Pending the preparation of definitive Securities, the Company may execute and deliver to the Trustee and, upon Company Order, the Trustee shall authenticate and deliver, in the manner provided in Section 303, temporary Securities in lieu thereof which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued, in registered form or, if authorized in or pursuant to this Indenture, in bearer form with one or more Coupons or without Coupons and with such appropriate insertions, omissions, substitutions and other variations as the officers of the Company executing such Securities may determine, as conclusively evidenced by their execution of such Securities. Such temporary Securities may be in global form.

Except in the case of temporary Securities in global form, which shall be exchanged in accordance with the provisions thereof, if temporary Securities are issued, the Company shall cause definitive Securities to be prepared without unreasonable delay. After the preparation of definitive Securities of the same series and containing terms and provisions that are identical to those of any temporary Securities, such temporary Securities shall be exchangeable for such definitive Securities upon surrender of such temporary Securities at an Office or Agency for such Securities, without charge to any Holder thereof. Upon surrender for cancellation of any one or

-22-

more temporary Securities (accompanied by any unmatured Coupons appertaining thereto), the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal amount of definitive Securities of authorized denominations of the same series and containing identical terms and provisions; provided, however, that no definitive Bearer Security, except as provided in or pursuant to this Indenture, shall be delivered in exchange for a temporary Registered Security; and provided, further, that a definitive Bearer Security shall be delivered in exchange for a temporary Bearer Security only in compliance with the conditions set forth in or pursuant to this Indenture. Unless otherwise provided in or pursuant to this Indenture with respect to a temporary global Security, until so exchanged the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of such series.

Section 305. Registration, Transfer and Exchange.

With respect to the Registered Securities of each series, if any, the Company shall cause to be kept a register (each such register being herein sometimes referred to as the “Security Register”) at an Office or Agency for such series in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of the Registered Securities of such series and of transfers of the Registered Securities of such series. Such Office or Agency shall be the “Security Registrar” for that series of Securities. Unless otherwise specified in or pursuant to this Indenture or the Securities, the Trustee shall be the initial Security Registrar for each series of Securities. The Company shall have the right to remove and replace from time to time the Security Registrar for any series of Securities; provided that no such removal or replacement shall be effective until a successor Security Registrar with respect to such series of Securities shall have been appointed by the Company and shall have accepted such appointment by the Company. In the event that the Trustee shall not be or shall cease to be Security Registrar with respect to a series of Securities, it shall have the right to examine the Security Register for such series at all reasonable times. There shall be only one Security Register for each series of Securities.

Upon surrender for registration of transfer of any Registered Security of any series at any Office or Agency for such series, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Registered Securities of the same series denominated as authorized in or pursuant to this Indenture, of a like aggregate principal amount bearing a number not contemporaneously outstanding and containing identical terms and provisions.

At the option of the Holder, Registered Securities of any series may be exchanged for other Registered Securities of the same series containing identical terms and provisions, in any authorized denominations, and of a like aggregate principal amount, upon surrender of the Securities to be exchanged at any Office or Agency for such series. Whenever any Registered Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Registered Securities which the Holder making the exchange is entitled to receive.

-23-

If provided in or pursuant to this Indenture, with respect to Securities of any series, at the option of the Holder, Bearer Securities of such series may be exchanged for Registered Securities of such series containing identical terms, denominated as authorized in or pursuant to this Indenture and in the same aggregate principal amount, upon surrender of the Bearer Securities to be exchanged at any Office or Agency for such series, with all unmatured Coupons and all matured Coupons in default thereto appertaining. If the Holder of a Bearer Security is unable to produce any such unmatured Coupon or Coupons or matured Coupon or Coupons in default, such exchange may be effected if the Bearer Securities are accompanied by payment in funds acceptable to the Company and the Trustee in an amount equal to the face amount of such missing Coupon or Coupons, or the surrender of such missing Coupon or Coupons may be waived by the Company and the Trustee if there is furnished to them such security or indemnity as they may require to save each of them and any Paying Agent harmless. If thereafter the Holder of such Bearer Security shall surrender to any Paying Agent any such missing Coupon in respect of which such a payment shall have been made, such Holder shall be entitled to receive the amount of such payment; provided, however, that, except as otherwise provided in Section 1002, interest represented by Coupons shall be payable only upon presentation and surrender of those Coupons at an Office or Agency for such series located outside the United States.

Notwithstanding the foregoing, in case a Bearer Security of any series is surrendered at any such Office or Agency for such series in exchange for a Registered Security of such series and like tenor after the close of business at such Office or Agency on (i) any Regular Record Date and before the opening of business at such Office or Agency on the relevant Interest Payment Date, or (ii) any Special Record Date and before the opening of business at such Office or Agency on the related date for payment of Defaulted Interest, such Bearer Security shall be surrendered without the Coupon relating to such Interest Payment Date or proposed date of payment, as the case may be (or, if such Coupon is so surrendered with such Bearer Security, such Coupon shall be returned to the Person so surrendering the Bearer Security), and interest or Defaulted Interest, as the case may be, shall not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of the Registered Security issued in exchange for such Bearer Security, but shall be payable only to the Holder of such Coupon when due in accordance with the provisions of this Indenture.

If provided in or pursuant to this Indenture with respect to Securities of any series, at the option of the Holder, Registered Securities of such series may be exchanged for Bearer Securities upon such terms and conditions as may be provided in or pursuant to this Indenture with respect to such series.

Whenever any Securities are surrendered for exchange as contemplated by the immediately preceding two paragraphs, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive.

Notwithstanding the foregoing, except as otherwise provided in or pursuant to this Indenture, any global Security shall be exchangeable for definitive Securities only if (i) the Depository is at any time unwilling, unable or ineligible to continue as Depository and a successor depository is not appointed by the Company within 90 days of the date the Company is so informed in writing, (ii) the Company executes and delivers to the Trustee a Company Order to the effect that such global Security shall be so exchangeable, or (iii) an Event of Default has occurred and is continuing with respect to the Securities. If the beneficial owners of interests in a global Security are entitled to exchange such interests for definitive Securities as the result of an event described in clause (i), (ii) or (iii) of the preceding sentence, then without unnecessary delay but in any event

not later than the earliest date on which such interests may be so exchanged, the Company shall deliver to the Trustee definitive Securities in such form and denominations as are required by or pursuant to this Indenture, and of the same series, containing identical terms and in aggregate principal amount equal to the principal amount of such global Security, executed by the Company. On or after the earliest date on which such interests may be so exchanged, such global Security shall be surrendered from time to time by the U.S. Depository or such other Depository as shall be specified in the Company Order with respect thereto, and in accordance with instructions given to the Trustee and the U.S. Depository or such other Depository, as the case may be (which instructions shall be in writing but need not be contained in or accompanied by an Officers’ Certificate or be accompanied by an Opinion of Counsel), as shall be specified in the Company Order with respect thereto to the Trustee, as the Company’s agent for such purpose, to be exchanged, in whole or in part, for definitive Securities as described above without charge. The Trustee shall authenticate and make available for delivery, in exchange for each portion of such surrendered global Security, a like aggregate principal amount of definitive Securities of the same series of authorized denominations and of like tenor as the portion of such global Security to be exchanged, which (unless such Securities are not issuable both as Bearer Securities and as Registered Securities, in which case the definitive Securities exchanged for the global Security shall be issuable only in the form in which the Securities are issuable, as provided in or pursuant to this Indenture) shall be in the form of Bearer Securities or Registered Securities, or any combination thereof, as shall be specified by the beneficial owner thereof, but subject to the satisfaction of any certification or other requirements to the issuance of Bearer Securities; provided, however, that no such exchanges may occur during a period beginning at the opening of business 15 days before any selection of Securities of the same series to be redeemed and ending on the relevant Redemption Date; and provided, further, that (unless otherwise provided in or pursuant to this Indenture) no Bearer Security delivered in exchange for a portion of a global Security shall be mailed or otherwise delivered to any location in the United States. Promptly following any such exchange in part, such global Security shall be returned by the Trustee to such Depository or the U.S. Depository, as the case may be, or such other Depository or U.S. Depository referred to above in accordance with the instructions of the Company referred to above. If a Registered Security is issued in exchange for any portion of a global Security after the close of business at the Office or Agency for such Security where such exchange occurs on or after (i) any Regular Record Date for such Security and before the opening of business at such Office or Agency on the next Interest Payment Date, or (ii) any Special Record Date for such Security and before the opening of business at such Office or Agency on the related proposed date for payment of interest or Defaulted Interest, as the case may be, interest shall not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of such Registered Security, but shall be payable on such Interest Payment Date or proposed date for payment, as the case may be, only to the Person to whom interest in respect of such portion of such global Security shall be payable in accordance with the provisions of this Indenture.

All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Company evidencing the same debt and entitling the Holders thereof to the same benefits under this Indenture as the Securities surrendered upon such registration of transfer or exchange.

-25-

Every Registered Security presented or surrendered for registration of transfer or for exchange or redemption shall (if so required by the Company or the Security Registrar for such Security) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar for such Security duly executed by the Holder thereof or his attorney duly authorized in writing.

No service charge shall be made for any registration of transfer or exchange, or redemption of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge.

Except as otherwise provided in or pursuant to this Indenture, the Company shall not be required (i) to issue, register the transfer of or exchange any Securities during a period beginning at the opening of business 15 days before the day of the selection for redemption of Securities of like tenor and the same series under Section 1103 and ending at the close of business on the day of such selection, or (ii) to register the transfer of or exchange any Registered Security so selected for redemption in whole or in part, except in the case of any Security to be redeemed in part, the portion thereof not to be redeemed, or (iii) to exchange any Bearer Security so selected for redemption except, to the extent provided with respect to such Bearer Security, that such Bearer Security may be exchanged for a Registered Security of like tenor and the same series, provided that such Registered Security shall be immediately surrendered for redemption with written instruction for payment consistent with the provisions of this Indenture or (iv) to issue, register the transfer of or exchange any Security which, in accordance with its terms, has been surrendered for repayment at the option of the Holder, except the portion, if any, of such Security not to be so repaid.

Section 306. Mutilated, Destroyed, Lost and Stolen Securities.

If any mutilated Security or a Security with a mutilated Coupon appertaining to it is surrendered to the Trustee, subject to the provisions of this Section 306, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series containing identical terms and of like principal amount and bearing a number not contemporaneously outstanding, with Coupons appertaining thereto corresponding to the Coupons, if any, appertaining to the surrendered Security.

If there be delivered to the Company and to the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security or Coupon, and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the Trustee that such Security or Coupon has been acquired by a bona fide purchaser, the Company shall execute and, upon Company Request the Trustee shall authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Security or in exchange for the Security to which a destroyed, lost or stolen Coupon appertains with all appurtenant Coupons not destroyed, lost or stolen, a new Security of the same series containing identical terms and of like principal amount and bearing a number not contemporaneously outstanding, with Coupons corresponding to the Coupons, if any, appertaining to such destroyed, lost or stolen Security or to the Security to which such destroyed, lost or stolen Coupon appertains.

-26-

Notwithstanding the foregoing provisions of this Section 306, in case any mutilated, destroyed, lost or stolen Security or Coupon has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security or Coupon; provided, however, that principal of, or any premium or interest on, any Bearer Securities shall, except as otherwise provided in Section 1002, be payable only at an Office or Agency for such Securities located outside the United States and, unless otherwise provided in or pursuant to this Indenture, any interest on Bearer Securities shall be payable only upon presentation and surrender of the Coupons appertaining thereto.

Upon the issuance of any new Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith.

Every new Security, with any Coupons appertaining thereto issued pursuant to this Section in lieu of any destroyed, lost or stolen Security, or in exchange for a Security to which a destroyed, lost or stolen Coupon appertains shall constitute a separate obligation of the Company, whether or not the destroyed, lost or stolen Security and Coupons appertaining thereto or the destroyed, lost or stolen Coupon shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of such series and the Coupons, if any, duly issued hereunder.

The provisions of this Section, as amended or supplemented pursuant to this Indenture with respect to particular Securities or generally, shall be exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities or Coupons.

Section 307. Payment of Interest; Rights to Interest Preserved.

Unless otherwise provided in or pursuant to this Indenture, any interest on any Registered Security which shall be payable, and are punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name such Security (or one or more Predecessor Securities) is registered as of the close of business on the Regular Record Date for such interest. Unless otherwise provided in or pursuant to this Indenture, in case a Bearer Security is surrendered in exchange for a Registered Security after the close of business at an Office or Agency for such Security on any Regular Record Date therefor and before the opening of business at such Office or Agency on the next succeeding Interest Payment Date therefor, such Bearer Security shall be surrendered without the Coupon relating to such Interest Payment Date and interest shall not be payable on such Interest Payment Date in respect of the Registered Security issued in exchange for such Bearer Security, but shall be payable only to the Holder of such Coupon when due in accordance with the provisions of this Indenture.

-27-

Unless otherwise provided in or pursuant to this Indenture, any interest on any Registered Security which shall be payable, but shall not be punctually paid or duly provided for, on any Interest Payment Date for such Registered Security (herein called “Defaulted Interest”) shall forthwith cease to be payable to the Holder thereof on the relevant Regular Record Date by virtue of having been such Holder; and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in Clause (1) or (2) below:

-28-

Unless otherwise provided in or pursuant to this Indenture or the Securities of any particular series, at the option of the Company, interest on Registered Securities that bear interest may be paid by mailing a check to the address of the Person entitled thereto as such address shall appear in the Security Register or by transfer to an account maintained by the payee with a bank located in the United States.

Subject to the foregoing provisions of this Section and Section 305, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security.

Section 308. Persons Deemed Owners.

Prior to due presentment of a Registered Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Registered Security is registered in the Security Register as the owner of such Registered Security for the purpose of receiving payment of principal of, and any premium and (subject to Sections 305 and 307) interest on, such Registered Security and for all other purposes whatsoever, whether or not any payment with respect to such Registered Security shall be overdue, and neither the Company, nor the Trustee or any agent of the Company or the Trustee shall be affected by notice to the contrary.

The Company, the Trustee and any agent of the Company or the Trustee may treat the bearer of any Bearer Security or the bearer of any Coupon as the absolute owner of such Security or Coupon for the purpose of receiving payment thereof or on account thereof and for all other purposes whatsoever, whether or not any payment with respect to such Security or Coupon shall be overdue, and neither the Company, nor the Trustee or any agent of the Company or the Trustee shall be affected by notice to the contrary.

No holder of any beneficial interest in any global Security held on its behalf by a Depository shall have any rights under this Indenture with respect to such global Security, and such Depository may be treated by the Company, the Trustee, and any agent of the Company or the Trustee as the owner of such global Security for all purposes whatsoever. None of the Company, the Trustee, any Paying Agent or the Security Registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a global Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

-29-

Section 309. Cancellation.

All Securities and Coupons surrendered for payment, redemption, registration of transfer or exchange shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee, and any such Securities and Coupons, as well as Securities and Coupons surrendered directly to the Trustee for any such purpose, shall be cancelled promptly by the Trustee. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Securities so delivered shall be cancelled promptly by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section, except as expressly permitted by or pursuant to this Indenture. Subject to the Trustee’s retention procedures, all cancelled Securities and Coupons held by the Trustee shall be destroyed by the Trustee, unless by a Company Order the Company directs their return to it.

Section 310. Computation of Interest.

Except as otherwise provided in or pursuant to this Indenture or in any Security, interest on the Securities shall be computed on the basis of a 360-day year of twelve 30-day months.

Section 311. CUSIP, Common Code and ISIN Numbers.

The Company in issuing the Securities may use “CUSIP”, “Common Code” and “ISIN” numbers and, if so, the Trustee shall use “CUSIP”, “Common Code” and “ISIN” numbers in notices of redemption or purchase as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption or purchase and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption or purchase shall not be affected by any defect in or omission of such CUSIP, Common Code and ISIN numbers. The Company shall promptly notify the Trustee in writing of any change in the CUSIP, Common Code and ISIN numbers.

(a) all Securities of such series theretofore authenticated and delivered and all Coupons appertaining thereto (other than (i) Coupons appertaining to Bearer Securities of such series surrendered in exchange for Registered Securities of such series and maturing after such exchange whose surrender is not required or has been waived as provided in Section 305, (ii) Securities and Coupons of such series which

(iii) if redeemable at the option of the Company, are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company, and the Company, in the case of (i), (ii) or (iii) above, has deposited or caused to be deposited with the Trustee as trust funds in trust for such purpose, money in the Currency in which such Securities are payable or Government Obligations (determined on the basis of the Currency in which such Securities are payable), in either case, in an amount sufficient to pay and discharge the entire Indebtedness on such Securities and any Coupons appertaining thereto not theretofore delivered to the Trustee for cancellation, including the principal of, and any premium and interest on, such Securities and any Coupons appertaining thereto, to the date of such deposit (in the case of Securities which have become due and payable) or to the Maturity thereof, as the case may be;

In the event there are Securities of two or more series hereunder, the Trustee shall be required to execute an instrument acknowledging satisfaction and discharge of this Indenture only if requested to do so with respect to Securities of such series as to which it is Trustee and if the other conditions thereto are met.

1. an amount in Dollars or in such Foreign Currency in which such Securities and any Coupons appertaining thereto are then specified as payable at Stated Maturity, or

2. Government Obligations applicable to such Securities and Coupons appertaining thereto (determined on the basis of the Currency in which such Securities and Coupons appertaining thereto are then specified as payable at Stated Maturity) which through the scheduled payment of principal and interest in respect thereof in accordance with their terms will provide, not later than one day before the due date of any payment of principal of (and premium, if any) and interest, if any, on such Securities and any Coupons appertaining thereto, money in an amount, or

-33-

3. a combination thereof, in any case, in an amount, sufficient, without consideration of any reinvestment of such principal and interest, in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (or if no nationally recognized investment bank, appraisal firm or firm of independent public accountants agrees to express such opinion, a certificate from the chief financial officer of the Company expressing his or her opinion) to pay and discharge, and which shall be applied by the Trustee (or other qualifying trustee) to pay and discharge, the principal of (and premium, if any) and interest, if any, on such Outstanding Securities and any Coupons appertaining thereto on the Stated Maturity of such principal or installment of principal or interest on the day on which such payments are due and payable in accordance with the terms of this Indenture and of such Securities and any Coupons appertaining thereto.

(b) Such defeasance or covenant defeasance shall not result in a breach or violation of, or constitute a default under, this Indenture or any other material agreement or instrument to which the Company is a party or by which it is bound.

(c) No Event of Default or event which with notice or lapse of time or both would become an Event of Default with respect to such Securities and any Coupons appertaining thereto shall have occurred and be continuing on the date of such deposit and, with respect to defeasance only, at any time during the period ending on the 91st day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until the expiration of such period).

(d) In the case of an election under clause (2) of this Section 402, the Company shall have delivered to the Trustee an Opinion of Counsel stating that (i) the Company has received from the Internal Revenue Service a letter ruling, or there has been published by the Internal Revenue Service a Revenue Ruling, or (ii) since the date of execution of this Indenture, there has been a change in the applicable Federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the beneficial owners of such Outstanding Securities and any Coupons appertaining thereto will not recognize income, gain or loss for Federal income tax purposes as a result of such defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such defeasance had not occurred.

(e) In the case of an election under clause (3) of this Section 402, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the beneficial owners of such Outstanding Securities and any Coupons appertaining thereto will not recognize income, gain or loss for Federal income tax purposes as a result of such covenant defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred.

-34-

(f) The Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent to the defeasance or covenant defeasance under clause (2) or (3) of this Section 402 (as the case may be) have been complied with.

Unless otherwise specified in or pursuant to this Indenture or any Security, if, after a deposit referred to in Section 402(4)(a) has been made, the Holder of a Security in respect of which such deposit was made is entitled to, and does, elect pursuant to Section 301 or the terms of such Security to receive payment in a Currency other than that in which the deposit pursuant to Section 402(4)(a) has been made in respect of such Security, the Indebtedness represented by such Security and any Coupons appertaining thereto shall be deemed to have been, and will be, fully discharged and satisfied through the payment of the principal of, and any premium and interest on, such Security as the same becomes due out of the proceeds yielded by converting (from time to time as specified below in the case of any such election) the amount or other property deposited in respect of such Security into the Currency in which such Security becomes payable as a result of such election based on the applicable market exchange rate for such Currency in effect on the second Business Day prior to each payment date.

The Company shall pay and indemnify the Trustee against any tax, fee or other charge, imposed on or assessed against the Government Obligations deposited pursuant to this Section 402 or the principal or interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of such Outstanding Securities and any Coupons appertaining thereto.

Anything in this Section 402 to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon Company Request any money or Government Obligations (or other property and any proceeds therefrom) held by it as provided in clause (4) of this Section 402 which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect a defeasance or covenant defeasance, as applicable, in accordance with this Section 402.

Section 404. Reinstatement.

If the Trustee or the Paying Agent is unable to apply any money in accordance with this Article with respect to any Securities by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the obligations under this Indenture and such Securities from which the Company has been discharged or released pursuant to this Article shall be revived and reinstated as though no deposit has occurred pursuant to this Article with respect to such Securities, until such time as the Trustee or Paying Agent is permitted to apply all money held in trust pursuant to this Article with respect to such Securities in accordance with this Article; provided, however, that if the Company makes any payment of principal of or any premium or interest on any such Security following reinstatement of its obligations, the Company shall be subrogated to the rights (if any) of the Holders of such Securities to receive such payment from the money so held in trust.

Section 501. Events of Default.

“Event of Default”, wherever used herein with respect to Securities of any series, means any one of the following events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body), unless such event is specifically deleted or modified in or pursuant to the supplemental indenture, Board Resolution or Officers’ Certificate establishing the terms of such series pursuant to this Indenture:

Section 502. Acceleration of Maturity; Rescission and Annulment.

If an Event of Default with respect to Securities of any series at the time Outstanding (other than an Event of Default specified in clause (4) or (5) of Section 501) occurs and is continuing, then the Trustee or the Holders of not less than 25% in principal amount of the Outstanding Securities of such series may declare the principal of all the Securities of such series, or such lesser amount as may be provided for in the Securities of such series, to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by the Holders), and upon any such declaration such principal or such lesser amount shall become immediately due and payable.

If an Event of Default specified in clause (4) or (5) of Section 501 occurs, all unpaid principal of and accrued interest on the Outstanding Securities of that series (or such lesser amount as may be provided for in the Securities of such series) shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder of any Security of that series.

At any time after Securities of any series have been accelerated and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of not less than a majority in principal amount of the Outstanding Securities of such series, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if

(a) all overdue installments of any interest on all Securities of such series and any Coupon appertaining thereto,

(b) the principal of and any premium on any Securities of such series which have become due otherwise than by such declaration of acceleration and interest thereon at the rate or rates borne by or provided for in such Securities,

(c) to the extent that payment of such interest is lawful, interest upon overdue installments of any interest at the rate or rates borne by or provided for in such Securities, and

(d) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and all other amounts due the Trustee under Section 606; and

-38-

No such rescission shall affect any subsequent default or impair any right consequent thereon.

Section 503. Collection of Indebtedness and Suits for Enforcement by Trustee.

The Company covenants that if

the Company shall, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of such Securities and any Coupons appertaining thereto, the whole amount of money then due and payable with respect to such Securities and any Coupons appertaining thereto, with interest upon the overdue principal, any premium and, to the extent that payment of such interest shall be legally enforceable, upon any overdue installments of interest at the rate or rates borne by or provided for in such Securities, and, in addition thereto, such further amount of money as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and all other amounts due to the Trustee under Section 606.

If the Company fails to pay the money it is required to pay the Trustee pursuant to the preceding paragraph forthwith upon the demand of the Trustee, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the money so due and unpaid, and may prosecute such proceeding to judgment or final decree, and may enforce the same against the Company or any other obligor upon such Securities and any Coupons appertaining thereto and collect the monies adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon such Securities and any Coupons appertaining thereto, wherever situated.

If an Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Securities of such series and any Coupons appertaining thereto by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or such Securities or in aid of the exercise of any power granted herein or therein, or to enforce any other proper remedy.

Section 504. Trustee May File Proofs of Claim.

In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor upon the Securities or the property of the Company or such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of any overdue principal, premium or interest) shall be entitled and empowered, by intervention in such proceeding or otherwise,

-39-

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder of Securities or any Coupons to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders of Securities or any Coupons, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and any other amounts due the Trustee under Section 606.

Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder of a Security or any Coupon any plan of reorganization, arrangement, adjustment or composition affecting the Securities or Coupons or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder of a Security or any Coupon in any such proceeding; provided, however, that the Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors’ committee or other similar committee.

Section 506. Application of Money Collected.

Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal, or any premium or interest, upon presentation of the Securities or Coupons, or both, as the case may be, and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

FIRST: To the payment of all amounts due the Trustee and any predecessor Trustee under Section 606;

SECOND: To the payment of the amounts then due and unpaid upon the Securities and any Coupons for principal and any premium and interest in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the aggregate amounts due and payable on such Securities and Coupons for principal and any premium and interest, respectively; and

THIRD: The balance, if any, to the Person or Persons entitled thereto.

Section 507. Limitations on Suits.

No Holder of any Security of any series or any Coupons appertaining thereto shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless

it being understood and intended that no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture or any Security to affect, disturb or prejudice the rights of any other such Holders or Holders of Securities of any other series, or to obtain or to seek to obtain priority or preference over any other Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all such Holders.

Section 611. Appointment of Authenticating Agent.

The Trustee may appoint one or more Authenticating Agents acceptable to the Company with respect to one or more series of Securities which shall be authorized to act on behalf of the Trustee to authenticate Securities of that or those series issued upon original issue, exchange, registration of transfer, partial redemption or partial repayment or pursuant to Section 306, and Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent.

An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company and shall (i) mail written notice of such appointment by first-class mail, postage prepaid, to all Holders of Registered Securities, if any, of the series with respect to which such Authenticating Agent shall serve, as their names and addresses appear in the Security Register, and (ii) if Securities of the series are issued as Bearer Securities, publish notice of such appointment at least once in an Authorized Newspaper in the place where such successor Authenticating Agent has its principal office if such office is located outside the United States. Any successor Authenticating Agent, upon acceptance of its appointment hereunder, shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section.

If all of the Securities of any series may not be originally issued at one time, and if the Trustee does not have an office capable of authenticating Securities upon original issuance located in a Place of Payment where the Company wishes to have Securities of such series authenticated upon original issuance, the Trustee, if so requested in writing (which writing need not be accompanied by or contained in an Officers’ Certificate by the Company), shall appoint in accordance with this Section an Authenticating Agent having an office in a Place of Payment designated by the Company with respect to such series of Securities.

Section 1002. Maintenance of Office or Agency.

If Securities of a series are issuable as Bearer Securities, the Company shall maintain, subject to any laws or regulations applicable thereto, an Office or Agency in a Place of Payment for such series which is located outside the United States where Securities of such series and any Coupons appertaining thereto may be presented and surrendered for payment; provided, however, that if the Securities of such series are listed on The Stock Exchange of the United Kingdom and the Republic of Ireland or the Luxembourg Stock Exchange or any other stock exchange located outside the United States and such stock exchange shall so require, the Company shall maintain a Paying Agent in London, Luxembourg or any other required city located outside the United States, as the case may be, so long as the Securities of such series are listed on such exchange.

The Company shall give prompt written notice to the Trustee of any such designation or rescission and

Section 1003. Money for Securities Payments to Be Held in Trust.

If the Company shall at any time act as its own Paying Agent with respect to any series of Securities, it shall, on or before each due date of the principal of, or any premium or interest on, any of the Securities of such series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum in the Currency or Currencies in which the Securities of such series are payable (except as otherwise specified pursuant to Section 301 for the Securities of such series) sufficient to pay the principal, premium or interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided, and shall promptly notify the Trustee of its action or failure so to act.

Whenever the Company shall have one or more Paying Agents for any series of Securities, it shall, on or prior to each due date of the principal of, or any premium or interest on, any Securities of such series, deposit with any Paying Agent a sum (in the Currency or Currencies described in the preceding paragraph) sufficient to pay the principal, premium or interest so becoming due, such sum to be held in trust for the benefit of the Persons entitled thereto, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to act.

The Company shall cause each Paying Agent for any series of Securities other than the Trustee to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent shall:

Except as otherwise provided herein or pursuant hereto, and subject to applicable escheat laws, any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, or any premium or interest on, any Security of any series or any Coupon appertaining thereto and remaining unclaimed for two years after such principal or any such premium or interest shall have become due and payable shall be paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security or any Coupon appertaining thereto shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, shall, upon receipt of a Company Request and at the expense of the Company, cause to be published once, in an Authorized Newspaper in each Place of Payment for such series or to be mailed to Holders of Registered Securities of such series, or both, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication or mailing nor shall it be later than two years after such principal, premium or interest shall have become due and payable, any unclaimed balance of such money then remaining will be repaid to the Company.

Section 1004. Limitation on Liens.

(e) Liens on any property securing (i) Indebtedness incurred in connection with the construction, installation or financing of pollution control or abatement facilities or other forms of industrial revenue bond financing, (ii) Indebtedness issued or guaranteed by the United States, any state or any department, agency or instrumentality of either or (iii) Indebtedness issued or guaranteed by (Y) a foreign government, any state or any department, agency or instrumentality of either or (Z) an international finance agency or any division or department thereof, including the World Bank, the International Finance Corp. and the Multilateral Investment Guarantee Agency;

(g) any Ordinary Course Lien (as defined below) arising, and only so long as continuing, in the ordinary course of the Company’s business; or

(h) Liens which secure Limited Recourse Indebtedness.

Section 1006. Waiver of Certain Covenants.

The Company may omit in any particular instance to comply with any term, provision or condition set forth in Sections 1004 or 1005 with respect to the Securities of any series if before the time for such compliance the Holders of at least a majority in principal amount of the Outstanding Securities of such series, by Act of such Holders, either shall waive such compliance in such instance or generally shall have waived compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect.

ARTICLE ELEVEN

REDEMPTION OF SECURITIES

Section 1101. Applicability of Article.

Redemption of Securities of any series at the option of the Company as permitted or required by the terms of such Securities shall be made in accordance with the terms of such Securities and (except as otherwise provided herein or pursuant hereto) this Article.

Section 1102. Election to Redeem; Notice to Trustee.

The election of the Company to redeem any Securities shall be evidenced by or pursuant to a Board Resolution or an Officers’ Certificate. In case of any redemption at the election of the Company of (a) less than all of the Securities of any series or (b) all of the Securities of any series, with the same issue date, interest rate or formula, Stated Maturity and other terms, the Company shall, at least seven days before notice of redemption is required to be sent to the Holders of Securities to be redeemed pursuant to Section 1104 hereof (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such Redemption Date and of the principal amount of Securities of such series to be redeemed.

-65-

Section 1103. Selection by Trustee of Securities to be Redeemed.

If less than all of the Securities of any series with the same issue date, interest rate or formula, Stated Maturity and other terms are to be redeemed, the particular Securities to be redeemed shall be selected not less than 10 nor more than 60 days prior to the Redemption Date by the Trustee from the Outstanding Securities of such series not previously called for redemption, on a pro rata basis (or, in the case of Securities issued in global form, based on the method as the U.S. Depository or other Depository for such Securities may require), unless otherwise required by law or applicable stock exchange or depositary requirements; provided, however, that no such partial redemption shall reduce the portion of the principal amount of a Registered Security of such series not redeemed to less than the minimum denomination for a Security of such series established herein or pursuant hereto.

The Trustee shall promptly notify the Company and the Security Registrar (if other than itself) in writing of the Securities selected for redemption and, in the case of any Securities selected for partial redemption, the principal amount thereof to be redeemed.

For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Securities redeemed or to be redeemed only in part, to the portion of the principal of such Securities which has been or is to be redeemed.

Section 1104. Notice of Redemption.

Notice of redemption shall be given in the manner provided in Section 106, not less than 10 nor more than 60 days prior to the Redemption Date, unless a shorter period is specified in the Securities to be redeemed, to the Holders of Securities to be redeemed; provided, however, such notice may be given more than 60 days prior to the Redemption Date if the notice is given in connection with a satisfaction and discharge of this Indenture with respect to any series pursuant to Section 4.01 herein. Failure to give notice in the manner herein provided to the Holder of any Registered Securities designated for redemption as a whole or in part, or any defect in the notice to any such Holder, shall not affect the validity of the proceedings for the redemption of any other Securities or portion thereof.

Any notice that is sent to the Holder of any Registered Securities in the manner herein provided shall be conclusively presumed to have been duly given, whether or not such Holder receives the notice.

All notices of redemption shall state:

-66-

A notice of redemption sent as contemplated by Section 106 need not identify particular Registered Securities to be redeemed.

Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the Company or, at the Company’s request, by the Trustee in the name and at the expense of the Company.

Section 1105. Deposit of Redemption Price.

On or prior to any Redemption Date, the Company shall deposit, with respect to the Securities of any series called for redemption pursuant to Section 1104, with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money in the applicable Currency sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date, unless otherwise specified pursuant to Section 301 or in the Securities of such series) any accrued interest on, all such Securities or portions thereof which are to be redeemed on that date.

-67-

Section 1106. Securities Payable on Redemption Date.

Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest or the condition or conditions precedent, if any with respect to the redemption described in the notice of redemption have not been satisfied) such Securities shall cease to bear interest and the Coupons for such interest appertaining to any Bearer Securities so to be redeemed, except to the extent provided below, shall be void. Upon surrender of any such Security for redemption in accordance with said notice, together with all Coupons, if any, appertaining thereto maturing after the Redemption Date, such Security shall be paid by the Company at the Redemption Price, together with any accrued interest to the Redemption Date; provided, however, that, except as otherwise provided in or pursuant to this Indenture or the Bearer Securities of such series, installments of interest on Bearer Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable only upon presentation and surrender of Coupons for such interest (at an Office or Agency located outside the United States except as otherwise provided in Section 1002), and provided, further, that, except as otherwise specified in or pursuant to this Indenture or the Registered Securities of such series, installments of interest on Registered Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the Regular Record Dates therefor according to their terms and the provisions of Section 307.

If any Bearer Security surrendered for redemption shall not be accompanied by all appurtenant Coupons maturing after the Redemption Date, such Security may be paid after deducting from the Redemption Price an amount equal to the face amount of all such missing Coupons, or the surrender of such missing Coupon or Coupons may be waived by the Company and the Trustee if there be furnished to them such security or indemnity as they may require to save each of them and any Paying Agent harmless. If thereafter the Holder of such Security shall surrender to the Trustee or any Paying Agent any such missing Coupon in respect of which a deduction shall have been made from the Redemption Price, such Holder shall be entitled to receive the amount so deducted; provided, however, that any interest represented by Coupons shall be payable only upon presentation and surrender of those Coupons at an Office or Agency for such Security located outside of the United States except as otherwise provided in Section 1002.

If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal and any premium, until paid, shall bear interest from the Redemption Date at the rate prescribed therefor in the Security.

Section 1107. Securities Redeemed in Part.

Any Registered Security which is to be redeemed only in part shall be surrendered at any Office or Agency for such Security (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing) and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new Registered Security or Securities of the same series, containing identical terms and provisions, of any authorized denomination as requested by such Holder in aggregate principal amount equal to and in exchange for the unredeemed portion of the

-68-

principal of the Security so surrendered. If a Security in global form is so surrendered, the Company shall execute, and the Trustee shall authenticate and deliver to the U.S. Depository or other Depository for such Security in global form as shall be specified in the Company Order with respect thereto to the Trustee, without service charge, a new Security in global form in a denomination equal to and in exchange for the unredeemed portion of the principal of the Security in global form so surrendered. In the case of a Security providing appropriate space for a notation of the payment for the redeemed portion of the Security, at the option of the Holder thereof, the Trustee, in lieu of delivering a new Security or Securities as aforesaid, may make a notation on such Security of the payment of the redeemed portion thereof.

ARTICLE TWELVE

REPAYMENT AT THE OPTION OF HOLDERS

Section 1201. Applicability of Article.

Securities of any series which are repayable at the option of the Holders thereof before their Stated Maturity shall be repaid in accordance with the terms of the Securities of such series. The repayment of any principal amount of Securities pursuant to such option of the Holder to require repayment of Securities before their Stated Maturity, for purposes of Section 309, shall not operate as a payment, redemption or satisfaction of the Indebtedness represented by such Securities unless and until the Company, at its option, shall deliver or surrender the same to the Trustee with a directive that such Securities be cancelled. Notwithstanding anything to the contrary contained in this Section 1201, in connection with any repayment of Securities, the Company may arrange for the purchase of any Securities by an agreement with one or more investment bankers or other purchasers to purchase such Securities by paying to the Holders of such Securities on or before the close of business on the repayment date an amount not less than the repayment price payable by the Company on repayment of such Securities, and the obligation of the Company to pay the repayment price of such Securities shall be satisfied and discharged to the extent such payment is so paid by such purchasers.

ARTICLE THIRTEEN

SECURITIES IN FOREIGN CURRENCIES

Section 1301. Applicability of Article.

Whenever this Indenture provides for (i) any action by, or the determination of any of the rights of, Holders of Securities of any series in which not all of such Securities are denominated in the same Currency, or (ii) any distribution to Holders of Securities, in the absence of any provision to the contrary in the form of Security of any particular series or pursuant to this Indenture or the Securities, any amount in respect of any Security denominated in a Currency other than Dollars shall be treated for any such action or distribution as that amount of Dollars that could be obtained for such amount on such reasonable basis of exchange and as of the record date with respect to Registered Securities of such series (if any) for such action, determination of rights or distribution (or, if there shall be no applicable record date, such other date reasonably proximate to the date of such action, determination of rights or distribution) as the Company may specify in a written notice to the Trustee or, in the absence of such written notice, as the Trustee may determine.

APA Corporation

2000 W. Sam Houston Pkwy S, Suite 200

Houston, Texas 77042

Ladies and Gentlemen:

We have acted as counsel to APA Corporation, a Delaware corporation (“APA”), in connection with the Post-Effective Amendment No. 1 (the “Post-Effective Amendment”) to the Registration Statement on Form S-3 (Registration No. 333-279038) (the “Initial Registration Statement” and, together with the Post-Effective Amendment, the “Registration Statement”) filed by APA with the Securities and Exchange Commission (the “Commission”) on the date hereof pursuant to the Securities Act of 1933, as amended (the “Act”), relating to the offering from time to time, pursuant to Rule 415 under the Securities Act, of, among other securities, an indeterminate principal amount of APA’s senior debt securities (the “Debt Securities”) to be issued pursuant to the Senior Indenture, dated as of December 11, 2024 (the “Indenture”), by and between APA and Regions Bank (the “Trustee”). We have been asked by APA to render this opinion.

We have examined originals, or copies certified or otherwise identified, of (i) the Registration Statement and the form of prospectus contained therein; (ii) the Amended and Restated Certificate of Incorporation of APA and the Amended and Restated Bylaws of APA, in each case as amended to date; (iii) the Indenture; (iv) corporate records of APA, including minute books of APA and certain resolutions of the Board of Directors, or committees thereof, of APA, as furnished to us by APA; and (v) such other instruments, documents and records as we have deemed necessary and relevant for the purposes hereof. We have relied upon certificates of officers of APA and of public officials as to certain matters of fact relating to this opinion and have made such investigations of law as we have deemed necessary and relevant as a basis hereof. In such examinations, we have assumed the legal capacity of all natural persons, the genuineness of all signatures, the authenticity of all documents, certificates and records submitted to us as originals, the conformity to authentic original documents, certificates and records of all documents, certificates and records submitted to us as copies, and the truthfulness of all statements of fact contained therein. We also have assumed the due execution and delivery of the Indenture by a duly authorized officer of the Trustee, and that the Commission filing fee with respect to any Debt Securities sold pursuant to the Registration Statement will be paid at the appropriate time. In making our examination of executed documents or documents to be executed, we have assumed that they constitute or will constitute valid, binding and enforceable obligations of all parties thereto other than APA.

In connection with this opinion, we have assumed that:

On the basis of the foregoing, and subject to the assumptions, limitations and qualifications set forth herein, we are of the opinion that with respect to any Debt Securities offered pursuant to the Registration Statement (the “Offered Debt Securities”), when (i) the Offered Debt Securities have been duly authorized for issuance, (ii) the terms thereof and of their respective issue and sale have been duly established and (iii) the Offered Debt Securities have been duly executed by APA and duly authenticated by the Trustee, upon the issuance and delivery of the Offered Debt Securities as contemplated by the Registration Statement and upon receipt by APA of the purchase price therefor, the Offered Debt Securities will be validly issued and legally binding obligations of APA, entitled to the benefits of the Indenture.

The foregoing opinion is based on and is limited to the General Corporation Law of the State of Delaware (the “DGCL”) and the relevant contract law of the State of New York. We express no opinion as to any other laws, statutes, regulations or ordinances, including federal and state securities (or “blue sky”) laws. The reference to the DGCL in the first sentence of this paragraph includes the referenced statutory provisions as well as all applicable provisions of the Delaware Constitution and the reported judicial cases interpreting those laws currently in effect.

In addition to the limitations and qualifications set forth above, the enforceability of obligations of APA under the Indenture and the Debt Securities is subject to (i) applicable bankruptcy, insolvency, reorganization, arrangement, fraudulent conveyance, moratorium or other similar laws relating to or affecting the rights of creditors generally, (ii) general principles of equity, including without limitation concepts of materiality, reasonableness, good faith and fair dealing, and the possible unavailability of specific performance or injunctive relief and limitation of rights of acceleration, regardless of whether such enforceability is considered in a proceeding in equity or at law and (iii) limitations of rights to indemnification, exculpation and contribution which may be limited by applicable law or equitable principles. We also express no opinion regarding the effectiveness of any waiver of stay, extension or usury laws or of unknown future rights, and we express no opinion regarding severability provisions. We express no opinion as to the validity, binding effect or enforceability of any provisions of the Indenture or the Debt Securities that require or relate to the payment of additional interest at a rate or in an amount that a court would determine in the circumstances under applicable law to be commercially unreasonable or a penalty or a forfeiture. Further, we express no opinion with respect to the enforceability of provisions in the Debt Securities or the Indenture with respect to waiver, delay, extension or omission of notice of enforcement of rights or remedies or waivers of defenses or waivers of benefits of stay, extension, moratorium, redemption, statutes of limitations or other nonwaivable benefits provided by operation of law. In addition, the enforceability of any exculpation, indemnification or contribution provisions contained in the Indenture may be limited by applicable law or public policy.
