Recent Developments

Marathon Acquisition

On November 22, 2024, ConocoPhillips completed the acquisition of Marathon Oil Corporation (“Marathon,” and the acquisition, the “Merger” or the “Marathon acquisition”) pursuant to a definitive agreement (the “Merger Agreement”). Pursuant to the Merger Agreement, which was unanimously approved by the boards of directors of both ConocoPhillips and Marathon and which was approved by Marathon stockholders, ConocoPhillips acquired the outstanding shares of Marathon in an all-stock transaction, pursuant to which Marathon stockholders received 0.255 shares of ConocoPhillips common stock per share of Marathon common stock and Marathon became a wholly-owned subsidiary of CPCo. For certain (i) historical consolidated financial statements of Marathon and (ii) unaudited pro forma combined financial statements of ConocoPhillips giving effect to the Marathon acquisition, see our Current Report on Form 8-K filed with the SEC on November 22, 2024 and incorporated by reference herein.

Concurrent Tender Offer and Exchange Offers

Substantially concurrently with the commencement of this offering, (a) CPCo has commenced a cash tender offer to purchase certain outstanding debt securities, including (i) any and all of the outstanding $4,000,000,000 senior notes issued by Marathon (the “Marathon Notes”) and (ii) certain outstanding debt securities issued by CPCo or ConocoPhillips, or their wholly-owned subsidiaries (the “Concurrent Tender Offer”), and (b) CPCo has commenced offers to exchange the Marathon Notes for up to $4,000,000,000 in aggregate principal amount of senior debt securities with the same maturity dates and interest rates as the corresponding Marathon Notes to be issued by CPCo and guaranteed by ConocoPhillips (the “Concurrent Exchange Offer”). In connection with each of the Concurrent Tender Offer and Concurrent Exchange

S-1

TABLE OF CONTENTS

Offer, Marathon is also soliciting consents with respect to each series of Marathon Notes in order to amend the existing indentures governing the terms of the Marathon Notes to eliminate, modify or remove certain restrictive covenants, events of default and other provisions contained in the indentures. ConocoPhillips intends to use the aggregate net proceeds of this offering to, subject to the terms and conditions of the Concurrent Tender Offer, purchase, on each settlement date, all notes that are validly tendered and not validly withdrawn and accepted for purchase pursuant to the Concurrent Tender Offer.

Concurrent Municipal Bond Remarketing

In connection with the Marathon acquisition, on November 22, 2024, Marathon launched the remarketing (the “Remarketing”) to investors of $400,000,000 aggregate principal amount of sub-series 2017C bonds that are part of the $1,000,000,000 St. John the Baptist Parish, State of Louisiana (the “Municipal Issuer”) revenue refunding bonds Series 2017 (the “Municipal Bonds”). The Municipal Bonds were originally issued in 2017 for the benefit of Marathon, with the proceeds being made available to Marathon and were used to refund a prior series of the Municipal Issuer’s revenue bonds. Pursuant to the Remarketing, ConocoPhillips will guarantee Marathon’s obligations under the Municipal Bonds.

Guarantees

ConocoPhillips will fully and unconditionally guarantee on a senior unsecured basis the full and prompt payment of the principal of and any premium and interest on the notes, when and as it becomes due and payable, whether at maturity or otherwise.

Ranking

The notes will constitute senior unsecured debt of CPCo and will rank:

•

equally with its senior unsecured debt from time to time outstanding;

•

senior to its subordinated debt from time to time outstanding; and

•

effectively junior to its secured debt and to all debt and other liabilities of its subsidiaries from time to time outstanding.

ConocoPhillips’ guarantees will rank equally with all of its other unsecured and unsubordinated debt from time to time outstanding.

S-3

TABLE OF CONTENTS

As of September 30, 2024, as adjusted on a pro forma basis assuming consummation of the Merger had occurred on such date, the assumption of the Marathon Notes, the Municipal Bonds remaining outstanding and the extinguishment of the Marathon revolving credit facility and commercial paper program, ConocoPhillips and CPCo would have had an aggregate of approximately $23.1 billion of consolidated total debt. Such amount does not give effect to this offering, the Concurrent Tender Offer or the Concurrent Exchange Offer. A substantial portion of such debt would have been either issued or guaranteed by ConocoPhillips, CPCo or both on a basis that would have ranked equally in right of payment with the notes and the related guarantees. As of September 30, 2024 CPCo had no secured indebtedness for borrowed money.

Covenants

We will issue the notes under an indenture containing covenants for your benefit. These covenants restrict our ability, with certain exceptions, to:

•

incur debt secured by liens;

•

engage in sale/leaseback transactions; and

•

merge, consolidate or transfer all or substantially all of CPCo’s or ConocoPhillips’ assets.

Lack of a Public Market for the Notes

There are no existing trading markets for the notes, and there can be no assurance regarding:

•

any future development or liquidity of a trading market for any series of notes;

•

your ability to sell your notes at all; or

•

the prices at which you may be able to sell your notes.

Future trading prices of the notes will depend on many factors, including:

•

prevailing interest rates;

•

our operating results and financial condition; and

•

the markets for similar securities.

We do not currently intend to apply for the listing of any series of notes on any securities exchange or for quotation of the notes in any dealer quotation system.

Use of Proceeds

We expect the net proceeds from the offering of the notes to be approximately $5.14 billion, after deducting underwriting discounts and estimated expenses of the offering that we will pay. We expect to use the net proceeds to, subject to the terms and conditions of the Concurrent Tender Offer, purchase, on each settlement date, all notes that are validly tendered and not validly withdrawn and accepted for purchase pursuant to the Concurrent Tender Offer, and with any proceeds remaining thereafter, for general corporate purposes, including the repayment of near-term indebtedness.

RISK FACTORS

Before making an investment in the notes, you should carefully consider the risk factors identified in Part I, Item 1A. “Risk Factors” of our Annual Report on Form 10-K for the year ended December 31, 2023. You should also carefully consider the other information set forth in this prospectus supplement, the accompanying prospectus, any free writing prospectus prepared by us or on our behalf and the documents incorporated by reference in this prospectus supplement before making an investment decision with respect to the notes. Additional risks and uncertainties not presently known to us, or that we currently deem immaterial, may also materially impair our business operations. The events discussed in the risk factors incorporated by reference in this prospectus supplement and the accompanying prospectus may occur.

Risks Related to the Notes

The issuer, CPCo, is dependent, in part, on the earnings of its subsidiaries.

CPCo holds a portion of its assets through direct and indirect ownership interests in, and conducts part of its business through, its subsidiaries. CPCo relies, in part, on dividends or other distributions from its subsidiaries, together with cash generated from its own operations, to meet its obligations for payment of principal and interest on its outstanding debt obligations and corporate expenses. Consequently, CPCo’s ability to service and to repay its debt when due, including the notes, may depend on the earnings of its subsidiaries, as well as its ability to receive funds from its subsidiaries through dividends or other payments or distributions. The ability of CPCo’s subsidiaries to pay dividends, repay intercompany debt or make other advances to it is subject to restrictions imposed by applicable laws (including bankruptcy laws), tax considerations and the terms of agreements governing its subsidiaries. CPCo’s foreign subsidiaries in particular may be subject to currency controls, repatriation restrictions, withholding obligations on payments to it, and other limits.

Because we, as the guarantor of the notes, are the direct parent entity of CPCo, the restrictions and constraints described above similarly apply to our ability to perform our obligations under the guarantee, including with respect to payments of principal and interest on the notes.

The notes are structurally subordinated to all of the indebtedness of CPCo’s subsidiaries.

The notes are CPCo’s general unsecured obligations and are not guaranteed by any of its subsidiaries. CPCo is a legal entity separate and distinct from its subsidiaries, and holders of the notes will be able to look only to it or to us, as guarantor of the notes, for payments on the notes. In addition, CPCo’s right to participate in any distribution of assets of any subsidiary upon its liquidation or reorganization or otherwise, and the ability of holders of the notes to benefit indirectly from that kind of distribution, is subject to the prior claims of creditors of that subsidiary, except to the extent that CPCo is recognized as a creditor of that subsidiary. All obligations of CPCo’s subsidiaries will have to be satisfied before any of the assets of such subsidiaries would be available for distribution, upon a liquidation or otherwise, to it. Accordingly, the notes are structurally subordinated to all existing and future liabilities of CPCo’s subsidiaries, including any Marathon Notes not purchased or exchanged in the Concurrent Transactions, and all liabilities of any of its future subsidiaries.

There are limited covenants governing the notes. These covenants do not restrict our ability to incur additional unsecured debt or to take other actions that could negatively impact holders of the notes.

The notes contain limited covenants, including those restricting ConocoPhillips’ ability and the ability of certain of its subsidiaries to incur certain debt secured by liens and engage in sale and leaseback transactions. Neither ConocoPhillips nor its subsidiaries are restricted under the terms of the notes from incurring additional unsecured debt, including additional senior debt under the indenture governing the notes or indebtedness under new or existing credit facilities, and we may opportunistically raise additional capital, including through additional indebtedness, to fund our capital plan and ongoing operations. In addition, the limited covenants applicable to the notes do not require us or our subsidiaries to achieve or maintain any minimum financial results relating to our or their financial position or results of operations. We may opportunistically raise additional capital, including through additional indebtedness, to fund our capital plan and ongoing operations. Further, the indenture does not contain provisions that would afford

S-11

TABLE OF CONTENTS

holders of the notes protection in the event of a sudden and significant decline in our credit quality or a takeover, recapitalization or highly leveraged or similar transaction. Our ability and the ability of our subsidiaries to recapitalize, incur additional debt and take a number of other actions that are not limited by the terms of the notes could adversely affect our capital structure or credit rating or have the effect of diminishing our ability to make payments on the notes when due. In addition, we and our subsidiaries are not restricted by the terms of the notes from repurchasing common stock or any subordinated indebtedness that we may incur in the future.

The notes and the guarantee will be effectively junior to all secured indebtedness of CPCo and ConocoPhillips, respectively.

The notes are CPCo’s senior unsecured obligations and rank equally with all its other unsecured indebtedness. The notes will be effectively subordinated to any secured debt CPCo may incur in the future to the extent of the value of the assets securing such debt. If CPCo defaults on the notes, becomes bankrupt, liquidates or reorganizes, any secured creditors could use its assets securing their debt to satisfy their secured debt before you would receive any payment on the notes. If the value of the collateral is not sufficient to pay any secured debt in full, CPCo’s secured creditors would share the value of its other assets, if any, with you and the holders of other claims against CPCo that rank equally with the notes.

ConocoPhillips’ guarantee is its senior unsecured obligation and ranks equally with all its other unsecured indebtedness, and, accordingly, its guarantee will be effectively subordinated to any secured debt it may incur in the future to the extent of the value of the assets securing such debt.

There is no established trading market for any series of the notes and you may not be able to sell the notes.

Each series of the notes is a new issue of securities with no established trading market. Although the underwriters may make a market in the notes of each series, they are not obligated to do so and any of their market making activities may be terminated or limited at any time. CPCo does not intend to apply for listing of any series of the notes on any securities exchange or for quotation on any automated dealer quotation system. Accordingly, you cannot be assured as to the liquidity of any market that may develop for any series of the notes, the ability of holders of the notes to sell their notes or the prices at which their notes could be sold. The liquidity of any market for any series of the notes will depend on the number of holders of those notes, the interest of securities dealers in making a market in those notes and other factors. Further, if markets were to develop, the market prices for the notes may be adversely affected by changes in our financial performance, changes in the overall market for similar securities and performance or prospects for companies in the same industry.

Changes in our credit ratings or the financial and credit markets could adversely affect the market price of notes.

The market price of the notes will be based on a number of factors, including:

•

our ratings with major credit rating agencies;

•

the prevailing interest rates being paid by companies similar to us;

•

our operating results, financial condition, financial performance and future prospects; and

•

the overall condition of the financial and credit markets.

We cannot be sure that credit rating agencies will maintain their ratings on the notes. Credit rating agencies continually review their ratings for the companies that they follow, including us, and revise those ratings as they believe warranted. The credit rating agencies also evaluate the oil and gas industries as a whole and may change their credit rating for us based on their overall view of our businesses, including the prospects for our major end user markets. A negative change in our credit ratings could have an adverse effect on the price of the notes.

In addition, the condition of the financial and credit markets and prevailing interest rates have fluctuated in the past and are likely to fluctuate in the future. In the past, there have been significant

S-12

TABLE OF CONTENTS

disruptions in the global economy, including volatile credit and capital market conditions. Fluctuations in these factors or a worsening of market conditions could have an adverse effect on the price of the notes.

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

The credit ratings assigned to the notes are limited in scope and do not address all material risks relating to an investment in the notes, but rather reflect only the view of each rating agency at the time the rating is issued. There can be no assurance that such credit ratings will remain in effect for any given period of time or that a rating will not be lowered, suspended or withdrawn entirely by the applicable rating agency, if, in such rating agency’s judgment, circumstances so warrant. Agency credit ratings are not a recommendation to buy, sell or hold any security. Each agency’s rating should be evaluated independently of any other agency’s rating. Actual or anticipated changes or downgrades in our credit ratings, including any announcement that our ratings are under review for a downgrade, could affect the market value of the notes and increase our corporate borrowing costs. None of us, CPCo, the trustee nor any underwriter undertakes any obligation to maintain the ratings or to advise holders of notes of any change in ratings.

We may choose to redeem any series of the notes prior to maturity.

We may redeem some or all of the notes at any time. See “Description of the Notes — Redemption.” If prevailing interest rates are lower at the time of redemption, you may not be able to reinvest the redemption proceeds in a comparable security at an interest rate as high as the interest rate of the notes being redeemed.

Risks Relating to the Merger

The unaudited pro forma combined financial statements included in or incorporated by reference in this prospectus supplement are presented for illustrative purposes only and do not represent the actual financial position or results of operations of ConocoPhillips following the completion of the Merger. Future results of ConocoPhillips or Marathon may differ, possibly materially, from the unaudited pro forma combined financial statements included in or incorporated by reference in this prospectus supplement.

The unaudited pro forma combined financial statements included in or incorporated by reference in this prospectus supplement is presented for illustrative purposes only, contains a variety of adjustments, assumptions and preliminary estimates and does not represent the actual financial position or results of operations of ConocoPhillips and Marathon prior to the Merger or that of ConocoPhillips following the Merger for several reasons. Specifically, the unaudited pro forma combined financial statements included in or incorporated by reference in this prospectus supplement do not reflect the effect of any potential divestitures that may occur subsequent to the completion of the Merger, integration costs or any changes in ConocoPhillips’ debt to capitalization ratio following the completion of the Merger, nor do they reflect this offering, the Concurrent Tender Offer or the Concurrent Exchange Offer. In addition, the post-Merger integration process may give rise to unexpected liabilities and costs, including costs associated with the defense and resolution of transaction-related litigation or other claims. The actual financial positions and results of ConocoPhillips following the Merger may be different, possibly materially, from the unaudited pro forma combined financial statements included in or incorporated by reference in this prospectus supplement. In addition, the assumptions used in preparing the unaudited pro forma combined financial information included in or incorporated by reference in this prospectus supplement may not prove to be accurate and may be affected by other factors. Any significant changes in the market price of ConocoPhillips common stock may cause a significant change in the purchase price used for ConocoPhillips’ accounting purposes and the unaudited pro forma combined financial statements included in or incorporated by reference in this prospectus supplement.

ConocoPhillips’ debt may limit its financial flexibility.

As of September 30, 2024, ConocoPhillips had approximately $18.304 billion of outstanding indebtedness, consisting of amounts outstanding under its unsubordinated notes and commercial paper program supported by its existing credit facility. As of September 30, 2024, Marathon had approximately $4.753 billion of outstanding indebtedness, consisting of amounts outstanding under (i) the Marathon Notes, (ii) its commercial paper program (ii) its Municipal Bonds, and in connection with which Marathon has

S-13

TABLE OF CONTENTS

agreed to make payments sufficient to pay the principal and interest thereon, and (iv) its revolving credit facility. Marathon’s commercial paper program and revolving credit facility have been terminated in connection with the consummation of the Merger. Substantially concurrently with the commencement of this offering, ConocoPhillips has commenced the Concurrent Tender Offer and Concurrent Exchange Offer with respect to the Marathon Notes.

ConocoPhillips’ pro forma indebtedness as of September 30, 2024, assuming consummation of the Merger had occurred on such date and the assumption of the Marathon Notes, the Municipal Bonds remaining outstanding and the extinguishment of the Marathon revolving credit facility and commercial paper program in connection therewith, is approximately $23.1 billion, representing an increase in comparison to ConocoPhillips’ indebtedness on a recent historical basis. Such amount does not give effect to this offering, the Concurrent Tender Offer or the Concurrent Exchange Offer. Any increase in ConocoPhillips’ indebtedness could have adverse effects on its financial condition and results of operations, including:

•

imposing additional cash requirements on ConocoPhillips in order to support interest payments, which reduces the amount ConocoPhillips has available to fund its operations and other business activities;

•

increasing the risk that ConocoPhillips may default on its debt obligations;

•

increasing ConocoPhillips’ vulnerability to adverse changes in general economic and industry conditions, economic downturns and adverse developments in its business;

•

limiting ConocoPhillips’ ability to sell assets, engage in strategic transactions or obtain additional financing for working capital, capital expenditures, general corporate and other purposes;

•

limiting ConocoPhillips’ flexibility in planning for or reacting to changes in its business and the industry in which it operates; and

•

increasing ConocoPhillips’ exposure to a rise in interest rates, which will generate greater interest expense to the extent ConocoPhillips does not have applicable interest rate fluctuation hedges.

TABLE OF CONTENTS

DESCRIPTION OF THE NOTES

We have summarized selected provisions of each series of the notes below. The notes will be issued under the indenture, dated as of December 7, 2012, among ConocoPhillips Company, as issuer, ConocoPhillips, as guarantor, and The Bank of New York Mellon Trust Company, N.A., as trustee (the “trustee”). Each series of the notes is a separate series of senior debt securities of ConocoPhillips Company described in the accompanying prospectus, and this summary supplements that description. We urge you to read that description for other provisions that may be important to you.

In this summary description of the notes, unless we state otherwise or the context clearly indicates otherwise, all references to CPCo mean ConocoPhillips Company only and all references to ConocoPhillips mean ConocoPhillips only.

General

The 2030 notes will mature on January 15, 2030 and will bear interest at 4.700% per year. The 2032 notes will mature on January 15, 2032 and will bear interest at 4.850% per year. The 2035 notes will mature on January 15, 2035 and will bear interest at 5.000% per year. The 2055 notes will mature on January 15, 2055 and will bear interest at 5.500% per year. The 2065 notes will mature on January 15, 2065 and will bear interest at 5.650% per year. Interest on the notes of each series will accrue from December 5, 2024. In respect of each series of notes, as applicable, CPCo:

•

will pay interest semiannually on January 15 and July 15 of each year, commencing July 15, 2025;

•

will pay interest on the notes on their respective maturity dates;

•

will pay interest to the person in whose name a note is registered at the close of business on the January 1 or July 1 preceding the interest payment date;

•

will compute interest on the basis of a 360-day year consisting of twelve 30-day months;

•

will make payments on the notes at the offices of the trustee and any paying agent; and

•

may make payments by wire transfer for notes held in book-entry form or by check mailed to the address of the person entitled to the payment as it appears in the note register.

CPCo will issue the notes only in fully registered form, without coupons, in minimum denominations of $2,000 and any integral multiples of $1,000 above that amount.

The 2030 notes will be limited initially to $1,350,000,000 in aggregate principal amount, the 2032 notes will be limited initially to $650,000,000 in aggregate principal amount, the 2035 notes will be limited initially to $1,250,000,000 in aggregate principal amount, the 2055 notes will be limited initially to $1,300,000,000 in aggregate principal amount and the 2065 notes will be limited initially to $650,000,000 in aggregate principal amount. We may, however, “reopen” each series of notes and issue an unlimited principal amount of additional notes of that series in the future without the consent of the holders. We may reopen a series of notes only if the additional notes issued will be fungible with the original notes of the series for U.S. federal income tax purposes.

As described in the prospectus, whether CPCo is in compliance with a restrictive covenant regarding limitations on liens will depend on whether the board of directors of ConocoPhillips has determined that a property or plant is a principal property. Though it has not yet done so, under the terms of the CPCo senior indenture (as defined in the prospectus) ConocoPhillips’ board of directors has broad discretion to determine from time to time after the issuance of any senior debt securities under the ConocoPhillips senior indenture (as defined in the prospectus) or the CPCo senior indenture that a property or plant is not a principal property and therefore such property or plant is not subject to the covenants in the CPCo senior indenture.

Redemption

Prior to the applicable Par Call Date, each series of the notes will be redeemable at CPCo’s option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

(1)

(a) the sum of the present values of the remaining scheduled payments of principal and interest

S-16

TABLE OF CONTENTS

thereon discounted to the redemption date (assuming the notes matured on the applicable Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 10 basis points, in the case of the 2030 notes, 10 basis points, in the case of the 2032 notes, 15 basis points, in the case of the 2035 notes, 20 basis points, in the case of the 2055 notes, and 20 basis points, in the case of the 2065 notes less (b) interest accrued to the date of redemption, and

(2)

100% of the principal amount of the notes to be redeemed,

plus, in each case, accrued and unpaid interest thereon to the redemption date.

On or after the Par Call Date, CPCo may redeem each series of the notes at a redemption price equal to 100% of the principal amount of the notes, plus accrued but unpaid interest thereon to the redemption date.

“Par Call Date” means in the case of the 2030 notes, December 15, 2029 (one month prior to maturity), in the case of the 2032 notes, November 15, 2031 (two months prior to maturity), in the case of the 2035 notes, October 15, 2034 (three months prior to maturity), in the case of the 2055 notes, July 15, 2054 (six months prior to maturity), and in the case of the 2065 notes, July 15, 2064 (six months prior to maturity).

“Treasury Rate” means, with respect to any redemption date, the yield determined by CPCo in accordance with the following two paragraphs.

The Treasury Rate shall be determined by CPCo after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily) — H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities — Treasury constant maturities — Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, CPCo shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the applicable Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields — one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life — and shall interpolate to the applicable Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

If on the third business day preceding the redemption date H.15 TCM is no longer published, CPCo shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the applicable Par Call Date. If there is no United States Treasury security maturing on the applicable Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the applicable Par Call Date, one with a maturity date preceding the applicable Par Call Date and one with a maturity date following the applicable Par Call Date, CPCo shall select the United States Treasury security with a maturity date preceding the applicable Par Call Date. If there are two or more United States Treasury securities maturing on the applicable Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, CPCo shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and

S-17

TABLE OF CONTENTS

asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

CPCo’s actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error. The Trustee shall have no responsibility to determine or calculate the redemption price or Treasury Rate.

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary’s procedures) at least 10 days but not more than 60 days before the redemption date to each holder of notes to be redeemed.

In the case of a partial redemption, selection of the notes for redemption will be made by lot, in the case of global notes held by The Depository Trust Company (“DTC”) (or another depositary), pursuant to the applicable depositary procedures. No notes of a principal amount of $2,000 or less will be redeemed in part. If any note is to be redeemed in part only, the notice of redemption that relates to the note will state the portion of the principal amount of the note to be redeemed. A new note in a principal amount equal to the unredeemed portion of the note will be issued in the name of the holder of the note upon surrender for cancellation of the original note.

Unless CPCo defaults in payment of the redemption price, on and after the redemption date interest will cease to accrue on the notes or portions thereof called for redemption.

Ranking

The notes will constitute senior unsecured debt of CPCo and will rank equally with each other series of notes and with CPCo’s other senior unsecured debt from time to time outstanding; senior to its subordinated debt from time to time outstanding; and effectively junior to its secured debt and to all debt and other liabilities of its subsidiaries from time to time outstanding. ConocoPhillips’ guarantees will rank equally with all of its other unsecured and unsubordinated debt from time to time outstanding.

Paying Agents and Transfer Agents

The trustee will be appointed as paying agent and transfer agent for the notes. Payments on the notes will be made in U.S. dollars at the office of the trustee and any paying agent. At our option, however, payments may be made by wire transfer for notes held in book-entry form or by wire transfer or by check mailed to the address of the person entitled to the payment as it appears in the security register, provided that payment by wire transfer will only be permitted with respect to any holder who holds at least $1,000,000 aggregate principal amount of notes and who has provided wire transfer instructions to us and the trustee or any paying agent to an account located in the continental United States.

Other

We will make all payments on the notes without withholding or deducting any taxes or other governmental charges imposed by a United States jurisdiction, unless we are required to do so by applicable law. A holder of the notes may, however, be subject to U.S. federal income taxes, and taxes may be withheld on certain payments on the notes, as described under the caption “Material U.S. Federal Tax Considerations.” If we are required to withhold taxes, we will not pay any additional, or gross up, amounts with respect to the withholding or deduction.

S-18

TABLE OF CONTENTS

We may at any time purchase notes on the open market or otherwise at any price. We will surrender all notes that we redeem or purchase to the trustee for cancellation. We may not reissue or resell any of these notes.

Book-Entry Delivery and Settlement

Global Notes

We will issue the notes of each series in the form of one or more permanent global notes in definitive, fully registered, book-entry form. The global notes will be deposited with or on behalf of DTC and registered in the name of Cede & Co., as nominee of DTC, or will remain in the custody of the trustee.

DTC, Clearstream and Euroclear

Beneficial interests in the global notes will be represented through book-entry accounts of financial institutions acting on behalf of beneficial owners as direct and indirect participants in DTC. Investors may hold interests in the global notes through either DTC (in the United States), Clearstream Banking, société anonyme, Luxembourg (“Clearstream”), or Euroclear Bank S.A./N.V. (the “Euroclear Operator”), as operator of the Euroclear System (in Europe) (“Euroclear”), either directly if they are participants of such systems or indirectly through organizations that are participants in such systems.

Clearstream and Euroclear will hold interests on behalf of their participants through customers’ securities accounts in Clearstream’s and Euroclear’s names on the books of their U.S. depositaries, which in turn will hold such interests in customers’ securities accounts in the U.S. depositaries’ names on the books of DTC. Citibank, N.A. will act as the U.S. depositary for Clearstream, and JPMorgan Chase Bank, N.A. will act as the U.S. depositary for Euroclear.

DTC has advised us as follows:

•

DTC is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered under Section 17A of the Securities Exchange Act of 1934.

•

DTC holds securities that its participants deposit with DTC and facilitates the settlement among participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in participants’ accounts, thereby eliminating the need for physical movement of securities certificates.

•

Direct participants include securities brokers and dealers, banks, trust companies, clearing corporations and other organizations.

•

DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”). DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries.

•

Access to the DTC system is also available to others such as securities brokers and dealers, banks and trust companies that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly.

•

The rules applicable to DTC and its direct and indirect participants are on file with the SEC. We have provided the descriptions of the operations and procedures of DTC, Clearstream and Euroclear in this prospectus supplement solely as a matter of convenience. These operations and procedures are solely within the control of those organizations and are subject to change by them from time to time. None of ConocoPhillips, CPCo, the underwriters nor the trustee takes any responsibility for these operations or procedures, and you are urged to contact DTC, Clearstream and Euroclear or their participants directly to discuss these matters.

We expect that under procedures established by DTC:

•

upon deposit of the global notes with DTC or its custodian, DTC will credit on its internal system the accounts of direct participants designated by the underwriters with portions of the principal amounts of the global notes; and

ownership of the notes will be shown on, and the transfer of ownership thereof will be effected only through, records maintained by DTC or its nominee, with respect to interests of direct participants, and the records of direct and indirect participants, with respect to interests of persons other than participants.

The laws of some jurisdictions may require that purchasers of securities take physical delivery of those securities in definitive form. Accordingly, the ability to transfer interests in the notes represented by a global note to those persons may be limited. In addition, because DTC can act only on behalf of its participants, who in turn act on behalf of persons who hold interests through participants, the ability of a person having an interest in notes represented by a global note to pledge or transfer those interests to persons or entities that do not participate in DTC’s system, or otherwise to take actions in respect of such interest, may be affected by the lack of a physical definitive security in respect of such interest.

So long as DTC or its nominee is the registered owner of a global note, DTC or that nominee will be considered the sole owner or holder of the notes represented by that global note for all purposes under the indenture and under the notes. Except as provided below, owners of beneficial interests in a global note will not be entitled to have notes represented by that global note registered in their names, will not receive or be entitled to receive physical delivery of certificated notes and will not be considered the owners or holders thereof under the indenture or under the notes for any purpose, including with respect to the giving of any direction, instruction or approval to the trustee. Accordingly, each holder owning a beneficial interest in a global note must rely on the procedures of DTC and, if that holder is not a direct or indirect participant, on the procedures of the participant through which that holder owns its interest, to exercise any rights of a holder of notes under the indenture or the global note.

None of ConocoPhillips, CPCo, the underwriters nor the trustee will have any responsibility or liability for any aspect of the records relating to or payments made on account of notes by DTC, Clearstream or Euroclear, or for maintaining, supervising or reviewing any records of those organizations relating to the notes.

Payments on the notes represented by the global notes will be made to DTC or its nominee, as the case may be, as the registered owner thereof. We expect that DTC or its nominee, upon receipt of any payment on the notes represented by a global note, will credit participants’ accounts with payments in amounts proportionate to their respective beneficial interests in the global note as shown in the records of DTC or its nominee. We also expect that payments by participants to owners of beneficial interests in the global note held through such participants will be governed by standing instructions and customary practice as is now the case with securities held for the accounts of customers registered in the names of nominees for such customers. The participants will be responsible for those payments.

Distributions on the notes held beneficially through Clearstream will be credited to cash accounts of its customers in accordance with its rules and procedures, to the extent received by the U.S. depositary for Clearstream.

Securities clearance accounts and cash accounts with the Euroclear Operator are governed by the Terms and Conditions Governing Use of Euroclear and the related Operating Procedures of the Euroclear System, and applicable Belgian law (collectively, the “Terms and Conditions”). The Terms and Conditions govern transfers of securities and cash within Euroclear, withdrawals of securities and cash from Euroclear, and receipts of payments with respect to securities in Euroclear. All securities in Euroclear are held on a fungible basis without attribution of specific certificates to specific securities clearance accounts. The Euroclear Operator acts under the Terms and Conditions only on behalf of Euroclear participants and has no record of or relationship with persons holding through Euroclear participants.

Distributions on the notes held beneficially through Euroclear will be credited to the cash accounts of its participants in accordance with the Terms and Conditions, to the extent received by the U.S. depositary for Euroclear.

Clearance and Settlement Procedures

Initial settlement for the notes will be made in immediately available funds. Secondary market trading between DTC participants will occur in the ordinary way in accordance with DTC rules and will be settled

S-20

TABLE OF CONTENTS

in immediately available funds. Secondary market trading between Clearstream customers and/or Euroclear participants will occur in the ordinary way in accordance with the applicable rules and operating procedures of Clearstream and Euroclear and will be settled using the procedures applicable to conventional eurobonds in immediately available funds.

Cross-market transfers between persons holding directly or indirectly through DTC, on the one hand, and directly or indirectly through Clearstream customers or Euroclear participants, on the other, will be effected in DTC in accordance with DTC rules on behalf of the relevant European international clearing system by the U.S. depositary; however, such cross-market transactions will require delivery of instructions to the relevant European international clearing system by the counterparty in such system in accordance with its rules and procedures and within its established deadlines (European time). The relevant European international clearing system will, if the transaction meets its settlement requirements, deliver instructions to the U.S. depositary to take action to effect final settlement on its behalf by delivering or receiving the notes in DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Clearstream customers and Euroclear participants may not deliver instructions directly to their U.S. depositaries.

Because of time-zone differences, credits of the notes received in Clearstream or Euroclear as a result of a transaction with a DTC participant will be made during subsequent securities settlement processing and dated the business day following the DTC settlement date. Such credits or any transactions in the notes settled during such processing will be reported to the relevant Clearstream customers or Euroclear participants on such business day. Cash received in Clearstream or Euroclear as a result of sales of the notes by or through a Clearstream customer or a Euroclear participant to a DTC participant will be received with value on the DTC settlement date but will be available in the relevant Clearstream or Euroclear cash account only as of the business day following settlement in DTC.

Although DTC, Clearstream and Euroclear have agreed to the foregoing procedures to facilitate transfers of the notes among participants of DTC, Clearstream and Euroclear, they are under no obligation to perform or continue to perform such procedures and such procedures may be changed or discontinued at any time.

Certificated Notes

We will issue certificated notes to each person that DTC identifies as the beneficial owner of the notes represented by the global notes upon surrender by DTC of the global notes if:

•

DTC notifies us that it is no longer willing or able to act as a depositary for the global notes, and we have not appointed a successor depositary within 90 days of that notice;

•

an event of default has occurred and is continuing, and DTC requests the issuance of certificated notes; or

•

we determine not to have the notes represented by a global note.

Neither we nor the trustee will be liable for any delay by DTC, its nominee or any direct or indirect participant in identifying the beneficial owners of the related notes. We and the trustee may conclusively rely on, and will be protected in relying on, instructions from DTC or its nominee for all purposes, including with respect to the registration and delivery, and the respective principal amounts, of the notes to be issued.

TABLE OF CONTENTS

MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following is a summary of material U.S. federal income tax considerations that may be relevant to the acquisition, ownership and disposition of the notes. This discussion is based upon the provisions of the Internal Revenue Code of 1986, as amended (the “Code”), applicable U.S. Treasury Regulations promulgated thereunder, judicial authority and administrative interpretations, all as of the date hereof and all of which are subject to change, possibly with retroactive effect, or subject to different interpretations. We cannot assure you that the IRS will not challenge one or more of the tax consequences described in this discussion, and we have not obtained, nor do we intend to obtain, a ruling from the IRS or an opinion of counsel with respect to the U.S. federal income tax consequences of acquiring, holding or disposing of the notes.

This discussion is limited to holders who purchase the notes in this offering for a price equal to the issue price of the notes (i.e., the first price at which a substantial amount of the notes is sold for cash other than to bond houses, brokers or similar persons or organizations acting in the capacity of initial purchasers, placement agents or wholesalers) and who hold the notes as capital assets (generally, property held for investment). This discussion does not address the tax considerations arising under the laws of any foreign, state, local or other jurisdiction or any income tax treaty or arising under any federal tax laws other than the laws applicable to federal income taxes. In addition, this discussion does not address all tax considerations that may be relevant to a particular holder in light of the holder’s circumstances, or to certain categories of investors that may be subject to special rules, such as dealers in securities or currencies, traders in securities that have elected the mark-to-market method of accounting for their securities, persons holding notes as part of a hedge, straddle, conversion or other “synthetic security” or other risk reduction transaction, U.S. expatriates, regulated investment companies, real estate investment trusts, persons subject to the alternative minimum tax, entities that are tax-exempt for U.S. federal income tax purposes, financial institutions, insurance companies, U.S. holders (as defined below) that have a functional currency other than the U.S. dollar, persons required to accelerate the recognition of any item of gross income with respect to the notes as a result of such income being recognized on an applicable financial statement, and partnerships and other pass-through entities and holders of interests therein.

Tax Consequences to U.S. Holders

You are a “U.S. holder” for purposes of this discussion if you are a beneficial owner of a note and you are for U.S. federal income tax purposes:

•

an individual who is a U.S. citizen or U.S. resident alien;

•

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

•

an estate whose income is subject to U.S. federal income taxation regardless of its source; or

•

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

Interest on the Notes

Interest on the notes generally will be taxable to you as ordinary income at the time it is received or accrued in accordance with your regular method of accounting for U.S. federal income tax purposes.

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

You will generally recognize capital gain or loss on the sale, redemption, exchange, retirement or other taxable disposition of a note. This gain or loss will equal the difference between the proceeds you receive (excluding any proceeds attributable to accrued but unpaid interest which will be recognized as ordinary interest income to the extent you have not previously included the accrued interest in income) and your tax basis in the note. The proceeds you receive will include the amount of any cash and the fair market value of

S-22

TABLE OF CONTENTS

any other property received for the note. Your tax basis in the note will generally equal the amount you paid for the note. The gain or loss will be long-term capital gain or loss if you held the note for more than one year at the time of the sale, redemption, exchange, retirement or other taxable disposition. Long-term capital gains of individuals, estates and trusts currently are subject to a reduced rate of U.S. federal income tax. The deductibility of capital losses is subject to limitation.

Information Reporting and Backup Withholding

Information reporting will apply to payments of interest on, and the proceeds of the sale, redemption, exchange, retirement or other taxable disposition of notes held by you, and backup withholding will apply to such payments and proceeds unless you provide the appropriate intermediary with a taxpayer identification number, certified under penalties of perjury, as well as certain other information or otherwise establish an exemption from backup withholding. Backup withholding is not an additional tax. Any amount withheld under the backup withholding rules is allowable as a credit against your U.S. federal income tax liability, if any, and a refund may be obtained if the amounts withheld exceed your actual U.S. federal income tax liability and you timely provide the required information or appropriate claim form to the IRS.

Additional Tax Relating to Net Investment Income

An additional 3.8% net investment income tax is imposed on certain “net investment income” earned by U.S. individuals, estates, and trusts. For this purpose, net investment income generally includes gross income from interest and net gain from the disposition of property, such as the notes, less certain deductions. In the case of an individual, the tax will be imposed on the lesser of (1) the individual’s net investment income or (2) the individual’s modified adjusted gross income in excess of $250,000 (for an individual who is married and filing jointly or a surviving spouse), $125,000 (for an individual who is married and filing separately) or $200,000 (in any other case). You should consult with your tax advisor with respect to the tax consequences of this additional tax.

Tax Consequences to Non-U.S. Holders

You are a “non-U.S. holder” for purposes of this discussion if you are a beneficial owner of a note and you are an individual, corporation (or other entity treated as a corporation for U.S. federal income tax purposes), estate or trust that is not a U.S. holder.

Interest on the Notes

Subject to the discussion below regarding backup withholding and the Foreign Account Tax Compliance Act, under the portfolio interest exemption, interest income on a note that you receive will not be subject to U.S. federal income tax or withholding tax if you are a non-U.S. holder, the interest is not effectively connected with the conduct of a trade or business in the United States by you and you:

•

do not own, actually or constructively, 10% or more of the total combined voting power of all classes of our voting stock;

•

are not a bank whose receipt of interest on a note is in connection with an extension of credit made pursuant to a loan agreement entered into in the ordinary course of business;

•

are not a controlled foreign corporation that is related, directly or indirectly, to us through sufficient stock ownership; and

•

provide the U.S. person who would otherwise be required to withhold tax from the interest with a properly completed IRS Form W-8BEN or IRS Form W-8BEN-E (or appropriate substitute or successor form) and certify on such form under penalties of perjury that the beneficial owner of the note is not a U.S. person.

If the portfolio interest exemption is not available with respect to interest on a note, then such interest may be subject to U.S. federal withholding tax at a rate of 30%. To claim an exemption from (or reduction in) withholding under the benefits of an applicable income tax treaty, you must provide a properly completed IRS Form W-8BEN or IRS Form W-8BEN-E, as applicable.

S-23

TABLE OF CONTENTS

Interest on a note that is effectively connected with the conduct of a trade or business in the U.S. by a non-U.S. holder of a note is not subject to withholding if such holder provides a properly completed IRS Form W-8ECI. However, such holder will generally be subject to U.S. income tax on such interest on a net income basis at rates applicable to a U.S. person, and a holder who is a foreign corporation may also be subject to the United States branch profits tax in respect of such interest.

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

Subject to the discussion below regarding backup withholding and the Foreign Account Tax Compliance Act, you generally will not be subject to U.S. federal income tax on any gain realized on the sale, redemption, exchange, retirement or other taxable disposition of a note unless the gain is effectively connected with your conduct of a trade or business in the United States or you are an individual who is present in the United States for 183 days or more in the taxable year in which the sale, redemption, exchange, retirement or other taxable disposition occurs and certain other conditions are met.

Information Reporting and Backup Withholding

The interest paid on a note to a non-U.S. holder will generally be reported to the IRS on IRS Form 1042-S. Generally, neither information reporting on IRS Form 1099 nor backup withholding will apply to principal or interest payments to a non-U.S. holder or to amounts received by a non-U.S. holder on the sale, redemption, exchange, retirement or other taxable disposition of a note if the non-U.S. holder has (i) furnished documentation establishing its eligibility for the portfolio interest exemption or a treaty exemption (as described above under “— Interest On the Notes”) or (ii) otherwise established an exemption from such information reporting and backup withholding requirements. However, the exemption from backup withholding and information reporting requirements does not apply if the withholding agent or an intermediary knows or has reason to know that such exemption is not available to you.

Foreign Account Tax Compliance Act

Sections 1471 through 1474 of the Code (referred to as “FATCA”) and Treasury Regulations thereunder, when applicable, will impose a U.S. federal withholding tax of 30% on any U.S.-source interest paid on debt obligations, such as the notes, and, subject to the discussion of proposed Treasury Regulations below, on the gross proceeds from the disposition of such debt obligations if paid to a “foreign financial institution” or a “non-financial foreign entity” (each as defined in the Code) (including, in some cases, when such foreign financial institution or non-financial foreign entity is acting as an intermediary), unless:

•

in the case of a foreign financial institution, such institution agrees to withhold on certain payments, and to collect and provide to the U.S. tax authorities information regarding U.S. account holders of such institution (which includes certain equity and debt holders of such institution, as well as certain account holders that are foreign entities with U.S. owners);

•

the non-financial foreign entity either certifies it does not have any “substantial U.S. owners” (as defined in the Code) or furnishes certain identifying information regarding each substantial U.S. owner; or

•

the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from these rules and provides appropriate documentation (such as the applicable IRS Form W-8 (or any successor form)).

The rules described above may be modified by an intergovernmental agreement entered into between the United States and another jurisdiction. Proposed Treasury Regulations eliminate withholding on payments of gross proceeds (but not on payments of interest). Pursuant to the preamble to the proposed Treasury Regulations, taxpayers may rely on the proposed regulations until final regulations are issued or the proposed regulations are withdrawn. Prospective purchasers of the notes are urged to consult their own tax advisors regarding the implications of FATCA on their investment in the notes.

This summary of material U.S. federal income tax considerations is for general information only and is not tax advice. You are urged to consult your tax advisor with respect to the application of U.S. federal tax laws to your particular situation as well as any tax consequences under the laws of any state, local, foreign or other taxing jurisdiction or under any applicable tax treaty.

The underwriters are committed to take and pay for all of the notes being offered, if any are taken.

The underwriters propose to offer the notes of each series directly to the public at the applicable public offering price set forth on the cover page of this prospectus supplement and may offer the notes to certain dealers at that public offering price less a concession not in excess of:

•

0.360% of the principal amount in the case of the 2030 notes;

•

0.375% of the principal amount in the case of the 2032 notes;

•

0.390% of the principal amount in the case of the 2035 notes;

•

0.525% of the principal amount in the case of the 2055 notes; and

•

0.525% of the principal amount in the case of the 2065 notes.

The underwriters may allow, and such dealers may reallow, a concession to certain other dealers not in excess of:

•

0.240% of the principal amount in the case of the 2030 notes;

•

0.250% of the principal amount in the case of the 2032 notes;

•

0.260% of the principal amount in the case of the 2035 notes;

0.350% of the principal amount in the case of the 2055 notes; and

•

0.350% of the principal amount in the case of the 2065 notes.

S-25

TABLE OF CONTENTS

After the initial offering of the notes to the public, the representatives may change the public offering prices and concessions.

The notes are new issues of securities with no established trading markets. We have been advised by the underwriters that the underwriters intend to make a market in each series of the notes but are not obligated to do so and may discontinue market making at any time without notice. No assurance can be given as to the liquidity of the trading markets for the notes.

In connection with the offering, the underwriters may purchase and sell notes 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 the underwriters of a greater number of notes than they are required to purchase in the 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 notes while the offering is in progress.

The underwriters also may impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the representatives have repurchased notes sold by or for the account of such underwriter in stabilizing or short covering transactions.

These activities by the underwriters, as well as other purchases by the underwriters for their own accounts, may stabilize, maintain or otherwise affect the market prices of the notes. As a result, the prices of the notes may be higher than the prices that otherwise might exist in the open market. If these activities are commenced, they may be discontinued by the underwriters at any time. These transactions may be effected in the over-the-counter market or otherwise.

We estimate that our share of the total expenses of the offering, excluding underwriting discounts and commissions, will be approximately $11.9 million.

We have agreed to indemnify the several underwriters against certain liabilities, including liabilities under the Securities Act of 1933.

The underwriters and certain of their affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage activities. The underwriters and certain of their affiliates have provided in the past, or are currently providing, other investment and commercial banking and financial advisory services to us or our affiliates, for which they received customary fees and expenses. For example, TD Securities (USA) LLC is lead arranger and bookrunner, an affiliate of TD Securities (USA) LLC is administrative agent, and affiliates of certain other underwriters are lenders to us under our term loan facility, which is guaranteed by CPCo. In addition certain of the underwriters, including TD Securities (USA) LLC and J.P. Morgan Securities LLC are or may become dealer managers in the Concurrent Exchange Offer and the Concurrent Tender Offer. The underwriters and their affiliates may in the future provide various investment and commercial banking and other services to us for which they would receive customary fees and expenses.

In addition, in the ordinary course of their business activities, the underwriters and their affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. If any of the underwriters or their affiliates have a lending relationship with us, certain of those underwriters or their affiliates routinely hedge, and certain other of those underwriters may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, these underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading

S-26

TABLE OF CONTENTS

prices of the notes offered hereby. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

Standard Chartered Bank will not effect any offers or sales of any notes in the United States unless it is through one or more U.S. registered broker-dealers as permitted by the regulations of the Financial Industry Regulatory Authority.

We expect that delivery of the notes will be made against payment therefor on or about December 5, 2024, which will be the seventh business day after the date of this prospectus supplement (such settlement being referred to as “T+7”). Under Rule 15c6-1 of the SEC under the Exchange Act, trades in the secondary market generally are required to settle in one business day, unless the parties to a trade expressly agree otherwise. Accordingly, purchasers who wish to trade notes more than one business day prior to the scheduled settlement date will be required, by virtue of the fact that the notes will initially settle in T+7, to specify an alternate settlement arrangement at the time of any such trade to prevent a failed settlement. Purchasers of such notes who wish to trade notes more than one business day before the scheduled settlement date should consult their advisors.

European Economic Area

The notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area (the “EEA”). For these purposes, a “retail investor” means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”); or (ii) a customer within the meaning of Directive (EU) 2016/97 (as amended), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in Regulation (EU) 2017/1129 (as amended, the “Prospectus Regulation”). Consequently, no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

United Kingdom

The notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the United Kingdom. For these purposes, a “retail investor” means a person who is one (or more) of: (i) a retail client, as defined in point (8) of Article 2 of Regulation (EU) No 2017/565 as it forms part of domestic law by virtue of the European Union (Withdrawal) Act 2018 (as amended, the “EUWA”); or (ii) a customer within the meaning of the provisions of the Financial Services and Markets Act 2000 (the “FSMA”) and any rules or regulations made under the FSMA to implement Directive (EU) 2016/97, where that customer would not qualify as a professional client, as defined in point (8) of Article 2(1) of Regulation (EU) No 600/2014 as it forms part of domestic law by virtue of the EUWA; or (iii) not a qualified investor as defined in Article 2 of Regulation (EU) 2017/1129 as it forms part of domestic law by virtue of the EUWA. Consequently, no key information document required by Regulation (EU) No 1286/2014 as it forms part of domestic law by virtue of the EUWA (the “UK PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail investors in the United Kingdom has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the United Kingdom may be unlawful under the UK PRIIPs Regulation.

Singapore

This prospectus supplement and the accompanying prospectus have not been registered as a prospectus with the Monetary Authority of Singapore.

FORWARD-LOOKING INFORMATION

This prospectus, including the information we incorporate by reference, includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, or the “Securities Act,” and Section 21E of the Exchange Act. All statements other than statements of historical fact included or incorporated by reference in this prospectus, including, without limitation, statements regarding our future financial position, business strategy, budgets, projected revenues, projected costs and plans, and objectives of management for future operations, are forward-looking statements. You can often identify our forward-looking statements by the words “anticipate,” “estimate,” “believe,” “budget,” “continue,” “could,” “intend,” “may,” “plan,” “potential,” “predict,” “seek,” “should,” “will,” “would,” “expect,” “objective,” “projection,” “forecast,” “goal,” “guidance,” “outlook,” “effort,” “target” and similar expressions.

We based the forward-looking statements on ConocoPhillips’ current expectations, estimates and projections about ConocoPhillips and the industries in which it operates in general. We caution you these statements are not guarantees of future performance as they involve assumptions that, while made in good faith, may prove to be incorrect, and involve risks and uncertainties we cannot predict. In addition, we based many of these forward-looking statements on assumptions about future events that may prove to be inaccurate. Accordingly, ConocoPhillips’ actual outcomes and results may differ materially from what we have expressed or forecast in the forward-looking statements. Any differences could result from a variety of factors and uncertainties, including, but not limited to, the following:

•

Fluctuations in crude oil, bitumen, natural gas, liquefied natural gas (“LNG”) and natural gas liquids (“NGLs”) prices, including a prolonged decline in these prices relative to historical or future expected levels.

•

The impact of significant declines in prices for crude oil, bitumen, natural gas, LNG and NGLs, which may result in recognition of impairment charges on our long-lived assets, leaseholds and nonconsolidated equity investments.

The potential for insufficient liquidity or other factors, such as those described herein, that could impact our ability to repurchase shares and declare and pay dividends, whether fixed or variable.

•

Potential failures or delays in achieving expected reserve or production levels from existing and future oil and gas developments, including due to operating hazards, drilling risks and the inherent uncertainties in predicting reserves and reservoir performance.

•

Reductions in reserves replacement rates, whether as a result of the significant declines in commodity prices or otherwise.

•

Unsuccessful exploratory drilling activities or the inability to obtain access to exploratory acreage.

•

Unexpected changes in costs, inflationary pressures or technical requirements for constructing, modifying or operating exploration and production (“E&P”) facilities.

•

Legislative and regulatory initiatives addressing environmental concerns, including initiatives addressing the impact of global climate change or further regulating hydraulic fracturing, methane emissions, flaring or water disposal.

•

Significant operational or investment changes imposed by existing or future environmental statutes and regulations, including international agreements and national or regional legislation and regulatory measures to limit or reduce greenhouse gas emissions.

•

Substantial investment in and development use of, competing or alternative energy sources, including as a result of existing or future environmental rules and regulations.

•

Liability for remedial actions, including removal and reclamation obligations, under existing and future environmental regulations and litigation.

Neither the ConocoPhillips senior indenture nor the subordinated indenture limits the amount of debt securities that may be issued under that indenture, and neither limits the amount of other unsecured debt or securities that ConocoPhillips may issue. ConocoPhillips may issue debt securities under the ConocoPhillips senior indenture and the subordinated indenture from time to time in one or more series, each in an amount authorized prior to issuance.

The CPCo senior indenture does not limit the amount of debt securities that may be issued under that indenture and does not limit the amount of other unsecured debt or securities that CPCo may issue. CPCo may issue debt securities under the CPCo senior indenture from time to time in one or more series, each in an amount authorized prior to issuance.

Each of ConocoPhillips and CPCo conducts substantially all its operations through subsidiaries, and those subsidiaries generate substantially all of ConocoPhillips’ and CPCo’s operating income and cash flow. As a result, distributions or advances from those subsidiaries are the principal source of funds necessary to meet the debt service obligations of ConocoPhillips and CPCo. Contractual provisions or laws, as well as the subsidiaries’ financial condition and operating requirements, may limit the ability of ConocoPhillips or CPCo to obtain cash from its subsidiaries that it requires to pay its debt service obligations, including any payments required to be made under the debt securities. In addition, holders of the debt securities will have a junior position to the claims of creditors of the subsidiaries of ConocoPhillips or CPCo, as applicable, on their assets and earnings.

Other than the restrictions contained in the senior indentures on liens and sale/leaseback transactions described below under “— Provisions Applicable Solely to Senior Debt Securities — Restrictive Covenants,” none of the indentures contains any covenants or other provisions designed to protect holders of the debt securities in the event ConocoPhillips or CPCo participates in a highly leveraged transaction or upon a change of control. The indentures also do not contain provisions that give holders the right to require

TABLE OF CONTENTS

ConocoPhillips or CPCo to repurchase their securities in the event of a decline in ConocoPhillips’ or CPCo’s credit ratings for any reason, including as a result of a takeover, recapitalization or similar restructuring or otherwise.

•

any other terms of the debt securities not inconsistent with the applicable indenture.

ConocoPhillips and CPCo may sell the debt securities at a discount, which may be substantially below their stated principal amount. These debt securities may bear no interest or interest at a rate that at the time of issuance is below market rates. If ConocoPhillips or CPCo sells these debt securities, the applicable prospectus supplement will describe any material United States federal income tax consequences and other special considerations.

If ConocoPhillips or CPCo sells any of the debt securities for any foreign currency or currency unit or if payments on the debt securities are payable in any foreign currency or currency unit, the applicable prospectus supplement will describe the restrictions, elections, tax consequences, specific terms and other information relating to those debt securities and the foreign currency or currency unit.

TABLE OF CONTENTS

Consolidation, Merger and Sale of Assets. The indentures generally permit a consolidation or merger involving ConocoPhillips or, with respect to the senior indentures, CPCo. They also permit ConocoPhillips or CPCo, as applicable, to lease, transfer or dispose of all or substantially all of its assets. Each of ConocoPhillips and, with respect to the senior indentures, CPCo has agreed, however, that it will not consolidate with or merge into any entity (other than, with respect to the senior indentures, ConocoPhillips or CPCo, as applicable) or lease, transfer or dispose of all or substantially all of its assets to any entity (other than, with respect to the senior indentures, ConocoPhillips or CPCo, as applicable) unless:

•

it is the continuing person; or

•

if it is not the continuing person, the resulting entity or transferee is organized and existing under the laws of any United States jurisdiction and assumes the performance of its covenants and obligations under the indentures and the due and punctual payments on the debt securities or the performance of the related guarantees, as applicable; and

•

in either case, immediately after giving effect to the transaction, no default or event of default would occur and be continuing or would result from the transaction.

Upon any such consolidation, merger or asset sale, lease, conveyance, transfer or other disposition involving ConocoPhillips or, with respect to the senior indentures, CPCo, the resulting entity or transferee will be substituted for ConocoPhillips or CPCo, as applicable, under the applicable indenture and debt securities. In the case of an asset transfer or disposition other than a lease, ConocoPhillips or CPCo, as applicable, will be released from the applicable indenture.

Modification and Waiver. Each indenture may be amended or supplemented if the holders of a majority in principal amount of the outstanding debt securities of all series issued under that indenture that are affected by the amendment or supplement (acting as one class) consent to it. Without the consent of the holder of each debt security affected, however, no modification may:

•

reduce the amount of debt securities whose holders must consent to an amendment, supplement or waiver;

•

reduce the rate of or change the time for payment of interest on the debt security;

•

reduce the principal of, any premium on or any mandatory sinking fund payment with respect to, or change the stated maturity of, any debt security or reduce the amount of the principal of an original issue discount security that would be due and payable upon a declaration of acceleration of the maturity thereof;

•

reduce any premium payable on the redemption of the debt security or change the time at which the debt security may or must be redeemed;

•

change any obligation to pay additional amounts on the debt security;

•

make payments on the debt security payable in currency other than as originally stated in the debt security;

•

impair the holder’s right to institute suit for the enforcement of any payment on or with respect to the debt security;

•

make any change in the percentage of principal amount of debt securities necessary to waive compliance with certain provisions of the indenture or to make any change in the provision related to modification;

•

with respect to the subordinated indenture, modify the provisions relating to the subordination of any subordinated debt security in a manner adverse to the holder of that security; or

•

waive a continuing default or event of default regarding any payment on the debt securities.

Each indenture may be amended or supplemented or any provision of that indenture may be waived without the consent of any holders of debt securities issued under that indenture in certain circumstances, including:

•

to cure any ambiguity, omission, defect or inconsistency;

TABLE OF CONTENTS

•

to provide for the assumption of the obligations under the indenture of ConocoPhillips or, with respect to the senior indentures, CPCo by a successor upon any merger, consolidation or asset transfer permitted under the indenture;

•

to provide for uncertificated debt securities in addition to or in place of certificated debt securities or to provide for bearer debt securities;

•

to provide any security for, any guarantees of or any additional obligors on any series of debt securities or, with respect to the ConocoPhillips senior indenture, the related guarantees;

•

to comply with any requirement to effect or maintain the qualification of that indenture under the Trust Indenture Act of 1939;

•

to add covenants that would benefit the holders of any debt securities or to surrender any rights ConocoPhillips or, with respect to the senior indentures, CPCo has under the indenture;

•

to add events of default with respect to any debt securities;

•

to make any change that does not adversely affect any outstanding debt securities of any series issued under that indenture in any material respect;

•

to establish the form or terms of debt securities of any series;

•

to supplement any of the provisions of an indenture to such extent as shall be necessary to permit or facilitate the defeasance and discharge of any series of debt securities; provided, however, that any such action shall not adversely affect the interest of the holders of debt securities of such series or any other series of debt securities in any material respect; and

•

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

The holders of a majority in principal amount of the outstanding debt securities of any series (or, in some cases, of all debt securities issued under the applicable indenture, voting as one class) may waive any existing or past default or event of default with respect to those debt securities. Those holders may not, however, waive any default or event of default in any payment on any debt security or compliance with a provision that cannot be amended or supplemented without the consent of each holder affected.

Defeasance. When we use the term defeasance, we mean discharge from some or all of the obligations of ConocoPhillips or CPCo, as applicable, under the indentures. If any combination of funds or government securities are deposited with the trustee under an indenture sufficient to make payments on the debt securities of a series issued under that indenture on the dates those payments are due and payable, then, at the option of ConocoPhillips, or with respect to the CPCo senior indenture, CPCo, either of the following will occur:

•

ConocoPhillips and, with respect to the senior indentures, CPCo will be discharged from its or their obligations with respect to the debt securities of that series and, if applicable, the related guarantees (“legal defeasance”); or

•

ConocoPhillips and, with respect to the senior indentures, CPCo will no longer have any obligation to comply with the restrictive covenants, the merger covenant and other specified covenants under the applicable indenture, and the related events of default will no longer apply (“covenant defeasance”).

If a series of debt securities is defeased, the holders of the debt securities of the series affected will not be entitled to the benefits of the applicable indenture, except for obligations to register the transfer or exchange of debt securities, replace stolen, lost or mutilated debt securities or maintain paying agencies and hold moneys for payment in trust. In the case of covenant defeasance, the obligation of ConocoPhillips or, with respect to the CPCo senior indenture, CPCo to pay principal, premium and interest on the debt securities and, if applicable, CPCo’s or ConocoPhillips’ guarantees of the payments will also survive.

Unless we inform you otherwise in the prospectus supplement, we will be required to deliver to the trustee an opinion of counsel that the deposit and related defeasance would not cause the holders of the debt

TABLE OF CONTENTS

securities to recognize income, gain or loss for U.S. federal income tax purposes. If we elect legal defeasance, that opinion of counsel must be based upon a ruling from the U.S. Internal Revenue Service or a change in law to that effect.

Governing Law. New York law will govern the indentures and the debt securities.

Trustee. The Bank of New York Mellon Trust Company, N.A. is the trustee under the senior indentures and will be the trustee under the subordinated indenture. The Bank of New York Mellon Trust Company, N.A. serves as trustee or custodian relating to a number of series of debt and other long-term repayment obligations of ConocoPhillips and its subsidiaries as of June 30, 2023. The Bank of New York Mellon Trust Company, N.A. and its affiliates perform certain commercial banking services for us for which they receive customary fees and are lenders under various outstanding credit facilities of subsidiaries of ConocoPhillips.

If an event of default occurs under an indenture and is continuing, the trustee under that indenture will be required to use the degree of care and skill of a prudent person in the conduct of that person’s own affairs. The trustee will become obligated to exercise any of its powers under that indenture at the request of any of the holders of any debt securities issued under that indenture only after those holders have offered the trustee indemnity satisfactory to it.

Each indenture contains limitations on the right of the trustee, if it becomes a creditor of ConocoPhillips or, if applicable, CPCo, to obtain payment of claims or to realize on certain property received for any such claim, as security or otherwise. The trustee is permitted to engage in other transactions with ConocoPhillips and, if applicable, CPCo. If, however, it acquires any conflicting interest, it must eliminate that conflict or resign within 90 days after ascertaining that it has a conflicting interest and after the occurrence of a default under the applicable indenture, unless the default has been cured, waived or otherwise eliminated within the 90-day period.

Form, Exchange, Registration and Transfer. The debt securities will be issued in registered form, without interest coupons. There will be no service charge for any registration of transfer or exchange of the debt securities. However, payment of any transfer tax or similar governmental charge payable for that registration may be required.

Debt securities of any series will be exchangeable for other debt securities of the same series, the same total principal amount and the same terms but in different authorized denominations in accordance with the applicable indenture. Holders may present debt securities for registration of transfer at the office of the security registrar or any transfer agent ConocoPhillips or, if applicable, CPCo designates. The security registrar or transfer agent will effect the transfer or exchange if its requirements and the requirements of the applicable indenture are met.

The trustee will be appointed as security registrar for the debt securities. If a prospectus supplement refers to any transfer agents ConocoPhillips or, if applicable, CPCo initially designates, ConocoPhillips or, if applicable, CPCo may at any time rescind that designation or approve a change in the location through which any transfer agent acts. ConocoPhillips and CPCo are required to maintain an office or agency for transfers and exchanges in each place of payment. ConocoPhillips and CPCo may at any time designate additional transfer agents for any series of debt securities.

In the case of any redemption, ConocoPhillips or, if applicable, CPCo will not be required to register the transfer or exchange of:

•

any debt security during a period beginning 15 business days prior to the mailing of the relevant notice of redemption or repurchase and ending on the close of business on the day of mailing of such notice; or

•

any debt security that has been called for redemption in whole or in part, except the unredeemed portion of any debt security being redeemed in part.

Payment and Paying Agents. Unless we inform you otherwise in a prospectus supplement, payments on the debt securities will be made in U.S. dollars at the office of the trustee and any paying agent. At the option of ConocoPhillips, or with respect to the CPCo senior debt securities, CPCo, however, payments may

TABLE OF CONTENTS

be made by wire transfer for global debt securities or by check mailed to the address of the person entitled to the payment as it appears in the security register. Unless we inform you otherwise in a prospectus supplement, interest payments may be made to the person in whose name the debt security is registered at the close of business on the record date for the interest payment.

Unless we inform you otherwise in a prospectus supplement, the trustee under the applicable indenture will be designated as the paying agent for payments on debt securities issued under that indenture.

ConocoPhillips or CPCo, as applicable, 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 the principal of or any premium or interest on debt securities of a series is payable on a day that is not a business day, the payment will be made on the following business day. For these purposes, unless we inform you otherwise in a prospectus supplement, a “business day” is any day that is not a Saturday, a Sunday or a day on which banking institutions in any of New York, New York; Houston, Texas or a place of payment on the debt securities of that series is authorized or obligated by law, regulation or executive order to remain closed.

Subject to the requirements of any applicable abandoned property laws, the trustee and paying agent will pay to us upon written request any money held by them for payments on the debt securities that remains unclaimed for two years after the date upon which that payment has become due. After payment to us, holders entitled to the money must look to us for payment. In that case, all liability of the trustee or paying agent with respect to that money will cease.

Book-Entry Debt Securities. The debt securities of a series may be issued in the form of one or more global debt securities that would be deposited with a depositary or its nominee identified in the prospectus supplement. Global debt securities may be issued in either temporary or permanent form. We will describe in the prospectus supplement the terms of any depositary arrangement and the rights and limitations of owners of beneficial interests in any global debt security.

Provisions Applicable Solely to Senior Debt Securities

Ranking. The ConocoPhillips senior debt securities will constitute senior debt of ConocoPhillips and will rank equally with all of its unsecured and unsubordinated debt from time to time outstanding. The CPCo senior debt securities will constitute senior debt of CPCo and will rank equally with all of its unsecured and unsubordinated debt from time to time outstanding.

Guarantee. Pursuant to the ConocoPhillips senior indenture, CPCo will fully and unconditionally guarantee on a senior unsecured basis the full and prompt payment of the principal of and any premium and interest on the senior debt securities issued by ConocoPhillips when and as the payment becomes due and payable, whether at maturity or otherwise. The guarantees provide that in the event of a default in the payment of principal of or any premium or interest on a ConocoPhillips senior debt security, the holder of that debt security may institute legal proceedings directly against CPCo to enforce the guarantees without first proceeding against ConocoPhillips. The guarantees will rank equally with all of CPCo’s other unsecured and unsubordinated debt from time to time outstanding.

Pursuant to the CPCo senior indenture, ConocoPhillips will fully and unconditionally guarantee on a senior unsecured basis the full and prompt payment of the principal of and any premium and interest on the senior debt securities issued by CPCo when and as the payment becomes due and payable, whether at maturity or otherwise. The guarantees provide that in the event of a default in the payment of principal of or any premium or interest on a CPCo senior debt security, the holder of that debt security may institute legal proceedings directly against ConocoPhillips to enforce the guarantees without first proceeding against CPCo. The guarantees will rank equally with all of ConocoPhillips’ other unsecured and unsubordinated debt from time to time outstanding.

Restrictive Covenants. ConocoPhillips has agreed to two principal restrictions on its activities for the benefit of holders of the ConocoPhillips senior debt securities and CPCo senior debt securities. The restrictive covenants summarized below will apply to a series of senior debt securities of ConocoPhillips or CPCo (unless waived or amended) as long as any of those debt securities are outstanding, unless the prospectus

TABLE OF CONTENTS

supplement for the series states otherwise. We have used in this summary description capitalized terms that we have defined below under “— Glossary.”

Limitation on Liens

ConocoPhillips has agreed that it and its Principal Domestic Subsidiaries will issue, assume or guarantee Debt for borrowed money secured by a lien upon a Principal Property or shares of stock or Debt of any Principal Domestic Subsidiary only if the outstanding senior debt securities are secured equally and ratably with or prior to the Debt secured by that lien. If the senior debt securities are so secured, ConocoPhillips has the option to secure any of its and its Subsidiaries’ other Debt or obligations equally and ratably with or prior to the Debt secured by the lien and, accordingly, equally and ratably with the senior debt securities. This covenant has exceptions that permit:

(a)

with respect to the ConocoPhillips senior indenture, liens existing on the date ConocoPhillips first issued a series of senior debt securities under such indenture and, with respect to the CPCo senior indenture, liens existing on the date CPCo first issues a series of senior debt securities under such indenture;

(b)

liens on the property, assets, stock, equity or Debt of any entity existing at the time ConocoPhillips or a Subsidiary acquires that entity or its property or at the time the entity becomes a Subsidiary or a Principal Domestic Subsidiary or at the time such entity is merged into or consolidated with ConocoPhillips or a Subsidiary or at the time of a sale, lease or other disposition of the properties of an entity as an entirety or substantially as an entirety to ConocoPhillips or a Subsidiary;

(c)

liens on assets either:

•

existing at the time of acquisition of the assets,

•

securing all of part of the cost of acquiring, constructing, improving, developing or expanding the assets, or

•

securing Debt incurred to finance all or part of the purchase price of the assets or the cost of constructing, improving, developing or expanding the assets that was incurred before, at the time of or within two years after the later of the acquisition, the completion of construction, improvement, development or expansion or the commencement of commercial operation of the assets;

(d)

liens on specific assets to secure Debt incurred to provide funds for the cost of exploration, drilling or development of those assets;

(e)

intercompany liens;

(f)

liens securing industrial development, pollution control or other revenue bonds of a domestic government entity;

(g)

liens on personal property, other than shares of stock or debt of any Principal Domestic Subsidiary, securing loans maturing in less than one year;

(h)

liens on a Principal Property arising in connection with the sale of accounts receivable resulting from the sale of oil or gas at the wellhead;

(i)

statutory or other liens arising in the ordinary course of business and relating to amounts that are not yet delinquent or are being contested in good faith; and

(j)

any extensions, substitutions, replacements or renewals of the above-described liens or any Debt secured by these liens if both:

•

the new lien is limited to the property (plus any improvements) secured by the original lien, and

•

the amount of Debt secured by the new lien and not otherwise permitted does not materially exceed the amount of Debt refinanced plus any premium or fee payable in connection with any such extension, substitution, replacement or renewal.

TABLE OF CONTENTS

In addition, without securing the senior debt securities as described above, ConocoPhillips and its Principal Domestic Subsidiaries may issue, assume or guarantee Debt that this covenant would otherwise restrict in a total principal amount that, when added to all other outstanding Debt of ConocoPhillips and its Principal Domestic Subsidiaries that this covenant would otherwise restrict and the total amount of Attributable Debt outstanding for Sale/Leaseback Transactions, does not exceed a “basket” equal to 10% of Consolidated Adjusted Net Assets. When calculating this total principal amount, we exclude from the calculation Attributable Debt from Sale/Leaseback Transactions in connection with which ConocoPhillips or a Subsidiary has purchased property or retired or defeased Debt as described in clause (b) below under “Limitation on Sale/Leaseback Transactions.”

The following types of transactions do not create “Debt” secured by “liens” within the meaning of this covenant:

(a)

the sale or other transfer of either:

•

oil, gas or other minerals in place for a period of time until, or in an amount such that, the purchaser will realize from those minerals a specified amount of money or a specified amount of those minerals, or

•

any other interest in property commonly referred to as a “production payment”; and

(b)

the mortgage or pledge of any property of ConocoPhillips or a Subsidiary in favor of the United States, any state of the United States or any department, agency, instrumentality or political subdivision of either, to secure payments under any contract or statute.

Limitation on Sale/Leaseback Transactions

ConocoPhillips has agreed that it and any of its Principal Domestic Subsidiaries will enter into a Sale/Leaseback Transaction only if at least one of the following applies:

(a)

ConocoPhillips or that Principal Domestic Subsidiary could incur Debt in a principal amount equal to the Attributable Debt for that Sale/Leaseback Transaction and, without violating the “Limitation on Liens” covenant, could secure that Debt by a lien on the property to be leased without equally and ratably securing the senior debt securities.

(b)

Within the period beginning one year before the closing of the Sale/Leaseback Transaction and ending one year after the closing, ConocoPhillips or any Subsidiary applies the net proceeds of the Sale/Leaseback Transaction either:

•

to the voluntary defeasance or retirement of any senior debt securities issued under the ConocoPhillips senior indenture (in the case of the ConocoPhillips senior indenture), senior debt securities issued under the CPCo senior indenture (in the case of the CPCo senior indenture) or any Funded Debt, or

•

to the acquisition, exploration, drilling, development, construction, improvement or expansion of one or more Principal Properties.

Any net proceeds that are not applied for the purposes described in (b) will be subject to the limitation described in (a). For purposes of these calculations, the net proceeds of the Sale/Leaseback Transaction means the net proceeds of the sale or transfer of the property leased in the Sale/Leaseback Transaction (or, if greater, the fair value of that property at the time of the Sale/Leaseback Transaction as determined by ConocoPhillips’ board of directors).

Provisions Applicable to Senior Debt Securities under the ConocoPhillips Senior Indenture and Subordinated Debt Securities

Events of Default. Unless otherwise described in the applicable prospectus supplement, the following are events of default with respect to a series of debt securities:

•

failure to pay interest on that series of debt securities for 30 days when due;

•

failure to pay principal of or any premium on that series of debt securities when due;

TABLE OF CONTENTS

•

failure to pay any sinking fund payment for 30 days when due;

•

failure to comply with any covenant or agreement in that series of debt securities or the applicable indenture (other than an agreement or covenant that has been included in the indenture solely for the benefit of other series of debt securities) for 90 days after written notice by the trustee or by the holders of at least 25% in principal amount of the outstanding debt securities issued under that indenture that are affected by that failure;

•

specified events involving bankruptcy, insolvency or reorganization of ConocoPhillips and, with respect to the senior debt securities, CPCo; and

•

any other event of default provided for that series of debt securities.

A default under one series of debt securities will not necessarily be a default under another series. The trustee may withhold notice to the holders of the debt securities of any default or event of default (except in any payment on the debt securities) if the trustee considers it in the interest of the holders of the debt securities to do so.

If an event of default for any series of debt securities occurs and is continuing, the trustee or the holders of at least 25% in principal amount of the outstanding debt securities of the series affected by the default (or, in some cases, 25% in principal amount of all debt securities issued under the applicable indenture that are affected, voting as one class) may declare the principal of and all accrued and unpaid interest on those debt securities to be due and payable. If an event of default relating to certain events of bankruptcy, insolvency or reorganization occurs, the principal of and interest on all the debt securities issued under the applicable indenture will become immediately due and payable without any action on the part of the trustee or any holder. The holders of a majority in principal amount of the outstanding debt securities of the series affected by the default (or, in some cases, of all debt securities issued under the applicable indenture that are affected, voting as one class) may in some cases rescind this accelerated payment requirement.

A holder of a debt security of any series issued under an indenture may pursue any remedy under that indenture only if:

•

the holder gives the trustee written notice of a continuing event of default with respect to that series;

•

the holders of at least 25% in principal amount of the outstanding debt securities of that series make a written request to the trustee to pursue the remedy;

•

the holders offer to the trustee indemnity satisfactory to the trustee against any loss, liability or expense;

•

the trustee does not comply with the request within 60 days after receipt of the request and offer of indemnity; and

•

during that 60-day period, the holders of a majority in principal amount of the debt securities of that series do not give the trustee a direction inconsistent with the request.

This provision does not, however, affect the right of a holder of a debt security to sue for enforcement of any overdue payment.

In most cases, holders of a majority in principal amount of the outstanding debt securities of a series (or of all debt securities issued under the applicable indenture that are affected, voting as one class) may direct the time, method and place of:

•

conducting any proceeding for any remedy available to the trustee; and

•

exercising any trust or power conferred on the trustee relating to or arising as a result of an event of default.

The ConocoPhillips senior indenture requires ConocoPhillips and CPCo, and the subordinated indenture requires ConocoPhillips, to file each year with the trustee a written statement as to their compliance with the covenants contained in the applicable indenture.

TABLE OF CONTENTS

Provisions Applicable Solely to Senior Debt Securities under the CPCo Senior Indenture

Events of Default. Unless otherwise described in the applicable prospectus supplement, the following are events of default with respect to a series of debt securities:

•

failure to pay interest on that series of debt securities for 30 days when due;

•

failure to pay principal of or any premium on that series of debt securities when due;

•

failure to pay any sinking fund payment for 30 days when due;

•

failure to comply with any covenant or agreement in that series of debt securities or the CPCo senior indenture (other than an agreement or covenant that has been included in the indenture solely for the benefit of other series of debt securities) for 90 days after written notice by the trustee or by the holders of at least 25% in principal amount of the outstanding debt securities issued under that indenture that are affected by that failure;

•

specified events involving bankruptcy, insolvency or reorganization of ConocoPhillips and CPCo; and

•

any other event of default provided for that series of debt securities.

If an event of default for any series of debt securities occurs and is continuing, the trustee or the holders of at least 25% in principal amount of the outstanding debt securities of the series affected by the default (or, in some cases, 25% in principal amount of all debt securities issued under the CPCo senior indenture that are affected, voting as one class) may declare the principal of and all accrued and unpaid interest on those debt securities to be due and payable. If an event of default relating to certain events of bankruptcy, insolvency or reorganization occurs, the principal of and interest on all the debt securities issued under the CPCo senior indenture will become immediately due and payable without any action on the part of the trustee or any holder. The holders of a majority in principal amount of the outstanding debt securities of the series affected by the default (or, in some cases, of all debt securities issued under the CPCo senior indenture that are affected, voting as one class) may in some cases rescind this accelerated payment requirement.

A holder of a debt security of any series issued under the CPCo senior indenture may pursue any remedy under that indenture only if:

•

the holder gives the trustee written notice of a continuing event of default with respect to that series;

•

the holders of at least 25% in principal amount of the outstanding debt securities of that series make a written request to the trustee to pursue the remedy;

•

the holders offer to the trustee indemnity satisfactory to the trustee against any loss, liability or expense;

•

the trustee does not comply with the request within 60 days after receipt of the request and offer of indemnity; and

•

during that 60-day period, the holders of a majority in principal amount of the debt securities of that series do not give the trustee a direction inconsistent with the request.

This provision does not, however, affect the right of a holder of a debt security to sue for enforcement of any overdue payment.

•

conducting any proceeding for any remedy available to the trustee; and

TABLE OF CONTENTS

•

exercising any trust or power conferred on the trustee relating to or arising as a result of an event of default.

The CPCo senior indenture requires ConocoPhillips and CPCo to file each year with the trustee a written statement as to their compliance with the covenants contained in the applicable indenture.

Glossary

“Attributable Debt” means the present value of the rental payments during the remaining term of the lease included in the Sale/Leaseback Transaction. To determine that present value, we use a discount rate equal to the lease rate of the Sale/Leaseback Transaction. For these purposes, rental payments do not include any amounts required to be paid for taxes, maintenance, repairs, insurance, assessments, utilities, operating and labor costs and other items that do not constitute payments for property rights. In the case of any lease that the lessee may terminate by paying a penalty, if the net amount (including payment of the penalty) would be reduced if the lessee terminated the lease on the first date that it could be terminated, then this lower net amount will be used.

“Consolidated Adjusted Net Assets” means the total amount of assets of ConocoPhillips and its consolidated subsidiaries less:

•

all current liabilities (excluding liabilities that are extendable or renewable at ConocoPhillips’ option to a date more than 12 months after the date of calculation and excluding current maturities of long-term debt); and

Provisions Applicable Solely to Subordinated Debt Securities

Ranking. The subordinated debt securities will rank junior to all Senior Debt of ConocoPhillips and may rank equally with or senior to other subordinated debt of ConocoPhillips that may be outstanding from time to time.

Subordination. Under the subordinated indenture, payment of the principal of and any premium and interest on the subordinated debt securities will generally be subordinated and junior in right of payment to the prior payment in full of all Senior Debt. Unless we inform you otherwise in the prospectus supplement, ConocoPhillips may not make any payment of principal of or any premium or interest on the subordinated debt securities if it fails to pay the principal, interest, premium or any other amounts on any Senior Debt when due.

The subordination does not affect ConocoPhillips’ obligation, which is absolute and unconditional, to pay, when due, the principal of and any premium and interest on the subordinated debt securities. In addition, the subordination does not prevent the occurrence of any default under the subordinated indenture.

The subordinated indenture does not limit the amount of Senior Debt that ConocoPhillips may incur. As a result of the subordination of the subordinated debt securities, if ConocoPhillips becomes insolvent, holders of subordinated debt securities may receive less on a proportionate basis than other creditors.

Unless we inform you otherwise in the prospectus supplement, “Senior Debt” will mean all debt, including guarantees, of ConocoPhillips, unless the debt states that it is not senior to the subordinated debt securities or other junior debt of ConocoPhillips. Senior Debt with respect to a series of subordinated debt securities could include other series of debt securities issued under the subordinated indenture.

TABLE OF CONTENTS

DESCRIPTION OF CAPITAL STOCK

The following description of ConocoPhillips’ common stock, preferred stock, certificate of incorporation and bylaws is a summary only and is subject to the complete text of ConocoPhillips’ certificate of incorporation and bylaws, which we have filed as exhibits to the registration statement. You should read those documents for provisions that may be important to you.

ConocoPhillips is authorized to issue 2.5 billion shares of common stock, par value $0.01 per share, and 500 million shares of preferred stock, par value $0.01 per share.

Common Stock

Each holder of ConocoPhillips common stock is entitled to one vote per share in the election of directors and on all other matters submitted to the vote of stockholders. However, except as otherwise required by law, holders of ConocoPhillips common stock are not entitled to vote on any amendment to ConocoPhillips’ certificate of incorporation that relates solely to the terms of any series of ConocoPhillips preferred stock if holders of the ConocoPhillips preferred stock are entitled to vote on the amendment under ConocoPhillips’ certificate of incorporation or Delaware law. There are no cumulative voting rights, meaning that the holders of a majority of the shares of ConocoPhillips common stock voting for the election of directors can elect all of the directors standing for election.

Subject to the rights of the holders of any series of ConocoPhillips preferred stock that may be outstanding from time to time, each share of ConocoPhillips common stock will have an equal and ratable right to receive dividends as may be declared by the ConocoPhillips board of directors out of funds legally available for the payment of dividends, and, in the event of the liquidation, dissolution or winding up of ConocoPhillips, will be entitled to share equally and ratably in the assets available for distribution to ConocoPhillips stockholders. No holder of ConocoPhillips common stock will have any preemptive or other subscription rights to purchase or subscribe for any securities of ConocoPhillips.

In addition, holders of ConocoPhillips common stock have no conversion rights, and there are no redemption or sinking fund provisions applicable to the ConocoPhillips common stock. ConocoPhillips common stock is traded on the New York Stock Exchange under the trading symbol “COP.” The transfer agent for the common stock is Computershare Shareowner Services LLC.

Preferred Stock

ConocoPhillips’ board of directors has the authority, without stockholder approval, to issue up to 500 million shares of preferred stock in one or more series and to fix the number of shares and terms of each series. The board may determine the designation and other terms of each series, including, among others:

•

dividend rights;

•

voting powers;

•

preemptive rights;

•

conversion rights;

•

redemption rights; and

•

liquidation preferences.

The prospectus supplement relating to any series of preferred stock ConocoPhillips is offering will include specific terms relating to the offering and the name of any transfer agent for that series. We will file the form of the preferred stock with the SEC before we issue any of it, and you should read it for provisions that may be important to you. The prospectus supplement will include some or all of the following terms:

•

the title of the preferred stock;

•

the maximum number of shares of the series;

•

the dividend rate or the method of calculating the dividend, the date from which dividends will accrue and whether dividends will be cumulative;

TABLE OF CONTENTS

•

any liquidation preference;

•

any optional redemption provisions;

•

any sinking fund or other provisions that would obligate us to redeem or purchase the preferred stock;

•

any terms for the conversion or exchange of the preferred stock for other securities of us or any other entity;

•

whether ConocoPhillips has elected to issue depositary shares with respect to the preferred stock as described below under “Description of Depositary Shares;”

•

any voting rights; and

•

any other preferences and relative, participating, optional or other special rights or any qualifications, limitations or restrictions on the rights of the shares.

The issuance of preferred stock, while providing desired flexibility in connection with possible acquisitions and other corporate purposes, could adversely affect the voting power of holders of ConocoPhillips’ common stock. It also could affect the likelihood that holders of the common stock will receive dividend payments and payments upon liquidation.

Anti-Takeover Provisions of ConocoPhillips’ Certificate of Incorporation and Bylaws

ConocoPhillips’ certificate of incorporation and bylaws contain provisions that could delay or make more difficult the acquisition of control of ConocoPhillips through a hostile tender offer, open market purchases, proxy contest, merger or other takeover attempt that a stockholder might consider in his or her best interest, including those attempts that might result in a premium over the market price of ConocoPhillips’ common stock.

Authorized but Unissued Stock

ConocoPhillips has 2.5 billion authorized shares of common stock and 500 million authorized shares of preferred stock. One of the consequences of ConocoPhillips’ authorized but unissued common stock and undesignated preferred stock may be to enable ConocoPhillips’ board of directors to make more difficult or to discourage an attempt to obtain control of ConocoPhillips. If, in the exercise of its fiduciary obligations, ConocoPhillips’ board of directors determined that a takeover proposal was not in ConocoPhillips’ best interest, the board could authorize the issuance of those shares without stockholder approval, subject to limits imposed by the New York Stock Exchange. The shares could be issued in one or more transactions that might prevent or make the completion of a proposed change of control transaction more difficult or costly by:

•

diluting the voting or other rights of the proposed acquiror or insurgent stockholder group;

•

creating a substantial voting block in institutional or other hands that might undertake to support the position of the incumbent board; or

•

effecting an acquisition that might complicate or preclude the takeover.

In this regard, ConocoPhillips’ certificate of incorporation grants its board of directors broad power to establish the rights and preferences of the authorized and unissued preferred stock. ConocoPhillips’ board could establish one or more series of preferred stock that entitle holders to:

•

vote separately as a class on any proposed merger or consolidation;

•

cast a proportionately larger vote together with ConocoPhillips common stock on any transaction or for all purposes;

•

elect directors having terms of office or voting rights greater than those of other directors;

•

convert preferred stock into a greater number of shares of ConocoPhillips common stock or other securities;

TABLE OF CONTENTS

•

demand redemption at a specified price under prescribed circumstances related to a change of control of ConocoPhillips; or

•

exercise other rights designed to impede a takeover.

Stockholder Action by Written Consent; Special Meetings of Stockholders

ConocoPhillips’ certificate of incorporation provides that no action that is required or permitted to be taken by its stockholders at any annual or special meeting may be taken by written consent of stockholders in lieu of a meeting, and that special meetings of stockholders may be called only by the board of directors or the chairman of the board.

Advance Notice Procedure for Director Nominations and Stockholder Proposals; Proxy Access

ConocoPhillips’ bylaws provide the manner in which stockholders may give notice of stockholder nominations and other business to be brought before an annual meeting. In general, to bring a matter before an annual meeting or to nominate a candidate for director, a stockholder must give notice of the proposed matter or nomination not less than 90 and not more than 120 days prior to the first anniversary date of the immediately preceding meeting. If the annual meeting is not within 30 days before or after the anniversary date of the preceding annual meeting, the stockholder notice must be received not earlier than the 120th day prior to the date of such annual meeting and not later than the close of business on the later of (1) 90 days prior to the date of the annual meeting or (2) if the first public announcement of the date of such annual meeting is less than 100 days prior to the date of the annual meeting, the close of business on the 10th day following the day on which notice of the annual meeting was mailed or first publicly disclosed.

In addition to the director nomination provisions described above, our by-laws contain a “proxy access” provision that provides that any stockholder or group of up to twenty stockholders who have owned 3% or more of our outstanding common stock continuously for at least three years to nominate and include in our proxy materials director candidates constituting up to 20% of our board of directors or two directors, whichever is greater, provided that the stockholders and the nominees satisfy the eligibility requirements specified in our by-laws. A stockholder proposing to nominate a person for election to our board of directors through the proxy access provision must provide us with a notice requesting the inclusion of the director nominee in our proxy materials and other required information not less than 120 days nor more than 150 days prior to the first anniversary of the date on which we first mail our proxy materials for the preceding year’s annual meeting of stockholders. In addition an eligible stockholder may include a written statement of not more than 500 words supporting the candidacy of such stockholder nominee. The complete proxy access provision for director nominations are set forth in our by-laws.

These procedures may limit the ability of stockholders to nominate candidates for director and bring other business before a stockholders meeting, including the consideration of any transaction that could result in a change of control and that might result in a premium to ConocoPhillips’ stockholders.

Fair Price Provision

ConocoPhillips’ certificate of incorporation requires that specified business combinations involving a person or entity that beneficially owns 15% or more of the outstanding shares of ConocoPhillips voting stock or that is an affiliate of that person, which we refer to as a related person, must be approved by (1) at least 80% of the votes entitled to be cast by the voting stock and (2) at least 66 2/3% of the votes entitled to be cast by the voting stock other than voting stock owned by the related person. These supermajority requirements do not apply if:

•

a majority of the directors who are unaffiliated with the related person and who were in office before the related person became a related person approve the transaction; or

•

specified fair price conditions are met that in general provide that the payment received by the stockholders in the business combination is not less than the amount the related person paid or agreed to pay for any shares of ConocoPhillips’ voting stock acquired within one year of the business combination.

TABLE OF CONTENTS

Amendment of Certificate of Incorporation and Bylaws

Amendments to ConocoPhillips’ certificate of incorporation generally must be approved by the board of directors and by a majority of the outstanding stock entitled to vote on the amendment, and, if applicable, by majority of the outstanding stock of each class or series entitled to vote on the amendment as a class or series.

Under the ConocoPhillips’ certificate of incorporation, the affirmative vote of shares representing not less than 80% of the votes entitled to be cast by the voting stock is required to alter, amend or adopt any provision inconsistent with or repeal the provisions that, among others, (1) control the constitution of the board of directors, (2) deny stockholders the right to call a special meeting or to act by written consent, (3) limit or eliminate the liability of directors of ConocoPhillips and (4) set the 80% supermajority threshold applicable with respect to the provisions above.

Additionally, the affirmative vote of shares representing (1) not less than 80% of the votes entitled to be cast by the voting stock, voting together as a single class, and (2) not less than 66 2/3% of the votes entitled to be cast by the voting stock not owned, directly or indirectly, by any related person is required to amend, repeal, or adopt any provisions inconsistent with, the fair price provision described above.

ConocoPhillips’ bylaws have similar supermajority vote requirements for provisions relating to, among others, special stockholder meetings; prohibition on action by stockholder written consent; nominating directors and bringing business before an annual stockholder meeting; the number, classification and qualification of directors; filling vacancies on the board of directors; and removing directors.

Limitation of Liability of Directors

To the fullest extent permitted by Delaware law, ConocoPhillips’ directors will not be personally liable to ConocoPhillips or its stockholders for monetary damages for breach of fiduciary duty as a director. Delaware law currently permits the elimination of all liability for breach of fiduciary duty, except liability:

•

for any breach of the duty of loyalty to ConocoPhillips or its stockholders;

•

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

•

for unlawful payment of a dividend or unlawful stock purchases or redemptions; and

•

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

As a result, neither ConocoPhillips nor its stockholders have the right, through stockholders’ derivative suits on ConocoPhillips’ behalf, to recover monetary damages against a director for breach of fiduciary duty as a director, including breaches resulting from grossly negligent behavior, except in the situations described above.

Delaware Anti-Takeover Law

ConocoPhillips is a Delaware corporation and is subject to Section 203 of the Delaware General Corporation Law, which regulates corporate acquisitions. Section 203 prevents an “interested stockholder,” which is defined generally as a person owning 15% or more of a corporation’s voting stock, or any affiliate or associate of that person, from engaging in a broad range of “business combinations” with the corporation for three years after becoming an interested stockholder unless:

•

the board of directors of the corporation had previously approved either the business combination or the transaction that resulted in the stockholder’s becoming an interested stockholder;

•

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

TABLE OF CONTENTS

•

following the transaction in which that person became an interested stockholder, the business combination is approved by the board of directors of the corporation and holders of at least two-thirds of the outstanding voting stock not owned by the interested stockholder.

Under Section 203, the restrictions described above also do not apply to specific business combinations proposed by an interested stockholder following the announcement or notification of designated extraordinary transactions involving the corporation and a person who had not been an interested stockholder during the previous three years or who became an interested stockholder with the approval of a majority of the corporation’s directors, if such extraordinary transaction is approved or not opposed by a majority of the directors who were directors prior to any person becoming an interested stockholder during the previous three years or were recommended for election or elected to succeed such directors by a majority of such directors.

Section 203 may make it more difficult for a person who would be an interested stockholder to effect various business combinations with a corporation for a three-year period.

TABLE OF CONTENTS

DESCRIPTION OF WARRANTS

TABLE OF CONTENTS

DESCRIPTION OF DEPOSITARY SHARES

General

ConocoPhillips may elect to offer shares of its preferred stock represented by depositary shares. The shares of any series of the preferred stock underlying the depositary shares will be deposited under a separate deposit agreement between ConocoPhillips and a bank or trust company we will name in the prospectus supplement.

Subject to the terms of the deposit agreement, each holder of a depositary share will be entitled, proportionately, to all the rights, preferences and privileges of the preferred stock represented by that depositary share, including dividend, voting, redemption, conversion, exchange and liquidation rights. The depositary shares will be evidenced by depositary receipts issued under the deposit agreement. Each receipt will represent the applicable interest in a number of shares of a particular series of the preferred stock, which we will describe in the prospectus supplement.

We have summarized below selected provisions of the deposit agreement, the related depositary shares and depositary receipts evidencing those shares. This summary is not complete. We will file the form of deposit agreement and the form of depositary receipts with the SEC before ConocoPhillips issues any depositary shares, and you should read those documents for provisions that may be important to you.

A holder of depositary shares will be entitled to receive the whole number of shares of preferred stock underlying those depositary shares. Holders will not be entitled to receive fractional shares. If the depositary receipts delivered by the holder evidence a number of depositary shares in excess of the whole number of shares to be withdrawn, the depositary will deliver to that holder at the same time a new depositary receipt for the excess number of depositary shares.

Dividends and Other Distributions

The depositary will distribute all cash dividends or other cash distributions received with respect to the preferred stock to the record holders of depositary receipts in proportion to the number of depositary shares owned by those holders.

If there is a distribution other than in cash, the depositary will distribute property received by it to the record holders of depositary receipts in proportion, insofar as possible, to the number of depositary shares owned by those holders. If the depositary determines that it is not feasible to make such a distribution, it may, with ConocoPhillips’ approval, adopt any method that it deems equitable and practicable to effect the distribution, including a sale of the property and distribution of the net proceeds from the sale to the holders.

The amount distributed in any of the above cases will be reduced by any amount ConocoPhillips or the depositary is required to withhold on account of taxes.

Conversion and Exchange

If any preferred stock underlying the depositary shares is subject to provisions relating to its conversion or exchange as described in the prospectus supplement, each record holder of depositary shares will have the right or obligation to convert or exchange those depositary shares in accordance with those provisions.

Redemption of Depositary Shares

Whenever ConocoPhillips redeems a share of preferred stock held by the depositary, the depositary will redeem on the same redemption date a proportionate number of depositary shares representing the shares of preferred stock redeemed. The redemption price per depositary share will be equal to the aggregate redemption price payable with respect to the number of shares of preferred stock underlying the depositary shares. If fewer than all the depositary shares are to be redeemed, the depositary shares to be redeemed will be selected by lot or proportionately as ConocoPhillips may determine.

Voting

Upon receipt of notice of any meeting at which the holders of the preferred stock underlying the depositary shares are entitled to vote, the depositary will mail the information contained in the notice to the

TABLE OF CONTENTS

record holders of the depositary receipts. Each record holder of the depositary receipts on the record date, which will be the same date as the record date for the preferred stock, may then instruct the depositary as to the exercise of the voting rights pertaining to the number of shares of preferred stock underlying that holder’s depositary shares. The depositary will try, as far as practicable, to vote the number of shares of preferred stock underlying the depositary shares in accordance with the instructions, and ConocoPhillips will agree to take all reasonable action that the depositary deems necessary to enable the depositary to do so. The depositary will abstain from voting the preferred stock to the extent that it does not receive specific written instructions from holders of depositary shares representing the preferred stock.

Record Date

Whenever:

•

any cash dividend or other cash distribution becomes payable, any distribution other than cash is made, or any rights, preferences or privileges are offered with respect to the preferred stock, or

•

the depositary receives notice of any meeting at which holders of preferred stock are entitled to vote or of which holders of preferred stock are entitled to notice, or of the mandatory conversion of or any election by ConocoPhillips to call for the redemption of any preferred stock,

the depositary will in each instance fix a record date, which will be the same as the record date for the preferred stock, for the determination of the holders of depositary receipts:

•

who will be entitled to receive the dividend, distribution, rights, preferences or privileges or the net proceeds of any sale, or

•

who will be entitled to give instructions for the exercise of voting rights at any such meeting or to receive notice of the meeting or the redemption or conversion.

Amendment and Termination of the Deposit Agreement

ConocoPhillips and the depositary may at any time agree to amend the form of depositary receipt and any provision of the deposit agreement. However, any amendment that adversely alters the rights of holders of depositary shares in any material respect will not be effective unless the amendment has been approved by the holders of at least a majority of the depositary shares then outstanding. The deposit agreement may be terminated by ConocoPhillips or by the depositary only if all outstanding depositary shares have been redeemed or if a final distribution on the underlying preferred stock has been made to the holders of the depositary shares in connection with the liquidation, dissolution or winding up of ConocoPhillips.

Charges of Depositary

ConocoPhillips will pay all charges of the depositary, including:

•

charges in connection with the initial deposit of the preferred stock;

•

the initial issuance of the depositary receipts;

•

the distribution of information to the holders of depositary receipts with respect to matters on which preferred stock is entitled to vote; and

•

withdrawals of the preferred stock by the holders of depositary receipts or upon redemption or conversion of the preferred stock.

Holders of depositary shares will pay taxes (including any transfer taxes) and other governmental charges and any other charges expressly provided in the deposit agreement to be at the expense of those holders.

TABLE OF CONTENTS

Resignation and Removal of Depositary

The depositary may at any time resign or be removed by ConocoPhillips. Any resignation or removal will become effective upon the acceptance by the depositary’s successor of its appointment. If ConocoPhillips has not appointed a successor depositary and the successor depositary has not accepted its appointment within 60 days after the depositary delivered a resignation notice to ConocoPhillips, the depositary may terminate the deposit agreement.

TABLE OF CONTENTS

DESCRIPTION OF STOCK PURCHASE CONTRACTS
AND STOCK PURCHASE UNITS

ConocoPhillips may issue stock purchase contracts, including contracts obligating holders to purchase from ConocoPhillips, and ConocoPhillips to sell to the holders, or for ConocoPhillips to issue in exchange for other securities, a specified number of shares of ConocoPhillips common stock or preferred stock or depositary shares (or a range of numbers of shares in accordance with a predetermined formula) at a future date or dates or upon the occurrence of specified events. The price per share of common stock or preferred stock or depositary share may be fixed at the time the stock purchase contracts are issued or may be determined by reference to a specific formula set forth in the stock purchase contracts.

ConocoPhillips may issue the stock purchase contracts separately or as a part of units, often known as stock purchase units, consisting of a stock purchase contract and any combination of senior debt securities or subordinated debt securities of ConocoPhillips or debt obligations of third parties, including U.S. Treasury securities, securing the holder’s obligations to purchase the common stock or preferred stock under the stock purchase contracts.

The stock purchase contracts may require ConocoPhillips to make periodic payments to the holders of the stock purchase units or vice versa, and those payments may be unsecured or prefunded on some basis. The stock purchase contracts may require holders to secure their obligations in a specified manner, and in specified circumstances, ConocoPhillips may deliver newly issued prepaid stock purchase contracts, often known as prepaid securities, upon release to a holder of any collateral securing that holder’s obligations under the original stock purchase contract.

The applicable prospectus supplement will describe the terms of any stock purchase contracts or stock purchase units and, if applicable, prepaid securities. That description will not be complete. For more information, you should review the stock purchase contracts and, if applicable, the collateral arrangements and depositary arrangements relating to those stock purchase contracts or stock purchase units and any prepaid securities and the document under which the prepaid securities will be issued. We will file forms of these documents with the SEC before ConocoPhillips issues any stock purchase contracts or stock purchase units and, if applicable, prepaid securities.

TABLE OF CONTENTS

PLAN OF DISTRIBUTION

We may sell the securities in and outside the United States through underwriters or dealers, directly to purchasers or through agents.

Sale Through Underwriters or Dealers

If we use underwriters in the sale of securities, the underwriters will acquire the securities for their own account. The underwriters may resell the securities from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. Underwriters may offer securities to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. Unless we inform you otherwise in the prospectus supplement, the obligations of the underwriters to purchase the securities will be subject to conditions, and the underwriters will be obligated to purchase all the securities if they purchase any of them. The underwriters may change from time to time any initial public offering price and any discounts or concessions allowed or re-allowed or paid to dealers.

During and after an offering through underwriters, the underwriters may purchase and sell the securities in the open market. These transactions may include overallotment and stabilizing transactions and purchases to cover syndicate short positions created in connection with the offering. The underwriters may also impose a penalty bid, whereby selling concessions allowed to syndicate members or other broker-dealers for the offered securities sold for their account may be reclaimed by the syndicate if such offered securities are repurchased by the syndicate in stabilizing or covering transactions. These activities may stabilize, maintain or otherwise affect the market price of the offered securities, which may be higher than the price that might otherwise prevail in the open market. If commenced, these activities may be discontinued at any time.

If we use dealers in the sale of securities, we will sell the securities to them as principals. They may then resell those securities to the public at varying prices determined by the dealers at the time of resale. The dealers participating in any sale of the securities may be deemed to be underwriters within the meaning of the Securities Act with respect to any sale of those securities. We will include in the prospectus supplement the names of the dealers and the terms of the transaction, including any compensation from sales of securities in the form of underwriting discounts or commissions.

Direct Sales and Sales Through Agents

We may sell the securities directly. In that event, no underwriters or agents would be involved. We may also sell the securities through agents we designate from time to time. In the prospectus supplement, we will name any agent involved in the offer or sale of the securities, and we will describe any commissions payable by us to the agent. Unless we inform you otherwise in the prospectus supplement, any agent will agree to use its reasonable best efforts to solicit purchases for the period of its appointment.

We may sell the securities directly to institutional investors or others who may be deemed to be underwriters within the meaning of the Securities Act with respect to any sale of those securities. We will describe the terms of any such sales in the prospectus supplement.

Delayed Delivery Contracts

If we so indicate in the prospectus supplement, we may authorize agents, underwriters or dealers to solicit offers from certain types of institutions to purchase securities from us at the public offering price under delayed delivery contracts. These contracts would provide for payment and delivery on a specified date in the future. The contracts would be subject only to those conditions described in the prospectus supplement. The prospectus supplement will describe the commission payable for solicitation of those contracts.

TABLE OF CONTENTS

General Information

We may have agreements with the agents, dealers and underwriters to indemnify them against civil liabilities, including liabilities under the Securities Act, or to contribute with respect to payments that the agents, dealers or underwriters may be required to make. Agents, dealers and underwriters may engage in transactions with us or perform services for us in the ordinary course of their businesses.
