ABOUT CONOCOPHILLIPS COMPANY

ConocoPhillips Company is a direct, wholly owned subsidiary of ConocoPhillips. Its principal executive offices are located at 600 North Dairy Ashford, Houston, Texas 77079, telephone (281) 293-1000. In this prospectus, we refer to ConocoPhillips Company as “CPCo.”

ABOUT THE CONOCOPHILLIPS TRUSTS

ConocoPhillips has formed two Delaware statutory trusts, ConocoPhillips Trust I and ConocoPhillips Trust II, to raise capital for ConocoPhillips by issuing preferred securities under this prospectus and investing the proceeds in debt securities issued by ConocoPhillips. Unless we inform you otherwise in the prospectus supplement relating to an offering of trust preferred securities, each trust will exist solely for the purposes of:

The trust preferred securities and the trust common securities of each trust will represent undivided beneficial interests in the assets of that trust. ConocoPhillips will directly or indirectly own all of the common securities of each trust. The common securities of each trust will represent an aggregate liquidation amount equal to at least three percent of the total capital of that trust. The common securities of each trust will rank equally with, and each trust will make payments on its common securities in proportion to, the trust preferred securities it issues. If, however, an event of default occurs under the declaration of trust of any of the trusts, including a default under the related series of ConocoPhillips’ debt securities, ConocoPhillips’ right to payments on the common securities of that trust will be subordinated to your rights as holder of its trust preferred securities.

The business and affairs of each trust will be conducted by its trustees. As the holder of the common securities of each trust, ConocoPhillips is entitled, except in limited circumstances, to appoint, and may remove

1

Table of Contents

or replace, the trustees. ConocoPhillips may increase or decrease the number of trustees for each trust, but each trust must have at least five trustees.

The duties and obligations of the trustees of each trust are governed by its declaration of trust. We will ensure that at least a majority of the trustees shall at all times be ConocoPhillips’ officers, directors or employees and that a financial institution unaffiliated with us acts as property trustee and indenture trustee for purposes of the Trust Indenture Act of 1939. In addition, unless the property trustee of a trust maintains a principal place of business in Delaware and meets the other requirements of applicable law, another trustee of that trust will have its principal place of business or reside in Delaware. We will appoint The Bank of New York Mellon Trust Company, N.A. to serve as property trustee for the trusts and BNY Mellon Trust of Delaware to serve as Delaware trustee for the trusts.

ConocoPhillips will pay all of the fees and expenses of each trust, including those related to any offering of trust preferred securities. In addition, ConocoPhillips will provide a guarantee with respect to each series of trust preferred securities issued by a trust under which ConocoPhillips will unconditionally and irrevocably agree to make certain payments to the holders of that series of trust preferred securities. That guarantee may, however, be subject to applicable subordination provisions and will apply only when the relevant trust has sufficient immediately available funds but fails to make the payments.

We will provide further information about the trusts in the prospectus supplement relating to an offering of trust preferred securities.

The principal office of each trust is c/o ConocoPhillips, 600 North Dairy Ashford, Houston, Texas 77079, telephone (281) 293-1000.

USE OF PROCEEDS

Unless we inform you otherwise in the prospectus supplement, the net proceeds from the sale of the securities will be used for general corporate purposes, including repayment or refinancing of debt, acquisitions, working capital, capital expenditures and repurchases and redemptions of securities. Pending any specific application, we may initially invest funds in short-term marketable securities or apply them to the reduction of other short-term indebtedness. Each trust will use all the proceeds received from the sale of its trust preferred securities and trust common securities to purchase debt securities issued by ConocoPhillips.

RATIO OF EARNINGS TO FIXED CHARGES AND EARNINGS TO COMBINED FIXED CHARGES AND PREFERRED STOCK DIVIDENDS

The following table presents the historical ratio of earnings to fixed charges of ConocoPhillips for the nine months ended September 30, 2012 and for each of the years in the five-year period ended December 31, 2011. ConocoPhillips had no preferred stock outstanding for any period presented, and accordingly its ratio of earnings to combined fixed charges and preferred stock dividends is the same as its ratio of earnings to fixed charges.

For the year ended December 31, 2008, earnings were deficient by $10.0 billion.

For purposes of this table, “earnings” consist of income from continuing operations before income taxes and noncontrolling interests that have not incurred fixed charges, plus fixed charges (excluding capitalized interest but including amortization of amounts previously capitalized), less undistributed earnings of equity investees of ConocoPhillips. “Fixed charges” consist of interest (including capitalized interest) on all debt, amortization of debt discounts and expenses incurred on issuance, interest expenses relating to guaranteed debt of fifty-percent-or-less-owned companies and that portion of rental expense believed to represent interest.

DESCRIPTION OF THE DEBT SECURITIES

The debt securities of ConocoPhillips covered by this prospectus will be general unsecured obligations of ConocoPhillips. ConocoPhillips will issue senior debt securities fully and unconditionally guaranteed by CPCo on a senior unsecured basis under an indenture, dated as of October 9, 2002, among ConocoPhillips, as issuer, CPCo, as guarantor, and The Bank of New York Mellon Trust Company, N.A., as trustee. We refer to this indenture as the ConocoPhillips senior indenture. ConocoPhillips will issue subordinated debt securities under an indenture to be entered into between ConocoPhillips and The Bank of New York Mellon Trust Company, N.A., as trustee. We refer to this indenture as the subordinated indenture.

The debt securities of CPCo covered by this prospectus will be general unsecured obligations of CPCo. CPCo will issue senior debt securities fully and unconditionally guaranteed by ConocoPhillips on a senior unsecured basis under an indenture to be entered into among CPCo, as issuer, ConocoPhillips, as guarantor, and The Bank of New York Mellon Trust Company, N.A., as trustee. We refer to this indenture as the CPCo senior indenture. We refer to the ConocoPhillips senior indenture and the CPCo senior indenture as the senior indentures and to the debt securities issued thereunder as the senior debt securities. We refer to the senior indentures and the subordinated indenture collectively as the indentures.

The ConocoPhillips senior indenture and the CPCo senior indenture will be substantially identical, except for the identity of the issuer and guarantor. The ConocoPhillips senior indenture and the subordinated indenture will be substantially identical, except for provisions relating to subordination and covenants.

We have summarized material provisions of the indentures, the debt securities and the guarantees below. This summary is not complete. We have filed the ConocoPhillips senior indenture, the form of subordinated indenture and the form of CPCo senior indenture with the SEC as exhibits to the registration statement, and you should read the indentures for provisions that may be important to you.

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

Provisions Applicable to Each Indenture

General. 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 indentures from time to time in one or more series, each in an amount authorized prior to issuance. ConocoPhillips’ 4.75% Notes due 2014, 4.60% Notes due 2015, 5.20% Notes due 2018, 5.75% Notes due 2019, 6.00% Notes due 2020, 5.90% Notes due 2032, 5.90% Notes due 2038 and 6.50% Notes due 2039 are outstanding under the ConocoPhillips senior indenture, and no securities are outstanding under the subordinated indenture.

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.

Table of Contents

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 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.

Terms. The prospectus supplement relating to any series of debt securities being offered will include specific terms relating to the offering. These terms will include some or all of the following:

7

Table of Contents

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.

Subsequent Distribution to Holders of Trust Securities. If ConocoPhillips issues debt securities to a ConocoPhillips trust in connection with the issuance of trust preferred securities and trust common securities by that trust, those debt securities subsequently may be distributed to the holders of those securities either:

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:

Upon any such consolidation, merger or asset lease, transfer or 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:

8

Table of Contents

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:

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

9

Table of Contents

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:

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 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 ConocoPhillips senior indenture and will be the trustee under the subordinated indenture and the CPCo senior indenture. The Bank of New York Mellon Trust Company, N.A. serves as trustee or custodian relating to a number of series of debt, trust preferred securities and other long-term repayment obligations of ConocoPhillips and its subsidiaries as of September 30, 2012. 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

10

Table of Contents

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:

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 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 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;

(c) liens on assets either:

12

Table of Contents

(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:

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:

(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 or instrumentality 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:

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:

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,

14

Table of Contents

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. If debt securities are issued to a ConocoPhillips trust, the related declaration of trust may require that any rescission be subject to the consent of the holders of the trust preferred securities and trust common securities issued by that trust.

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

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:

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.

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:

15

Table of Contents

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 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:

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:

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

16

Table of Contents

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:

ConocoPhillips will calculate its Consolidated Adjusted Net Assets based on its most recent quarterly balance sheet.

“Debt” means all notes, bonds, debentures or other similar evidences of debt for money borrowed.

“Funded Debt” means all Debt that matures on or is renewable to a date more than one year after the date the Debt is incurred.

“Principal Domestic Subsidiary” means any Subsidiary (1) that has substantially all its assets in the United States, (2) that owns a Principal Property and (3) in which ConocoPhillips’ capital investment, together with any intercompany loans to that Subsidiary and any debt of that Subsidiary guaranteed by ConocoPhillips or any other Subsidiary, exceeds $100 million. CPCo is a Principal Domestic Subsidiary of ConocoPhillips.

“Principal Property” means any oil or gas producing property located onshore or offshore of the United States or any refinery or manufacturing plant located in the United States. This term excludes any property, refinery or plant that in the opinion of ConocoPhillips’ board of directors is not materially important to the total business conducted by ConocoPhillips and its consolidated subsidiaries. This term also excludes any transportation or marketing facilities or assets.

“Sale/Leaseback Transaction” means any arrangement with anyone under which ConocoPhillips or a Subsidiary leases any Principal Property that ConocoPhillips or that Subsidiary has sold or transferred or will sell or transfer to that person. This term excludes the following:

“Subsidiary” means an entity at least a majority of the outstanding voting stock of which is owned, directly or indirectly, by ConocoPhillips or by one or more other Subsidiaries, or by ConocoPhillips and one or more other Subsidiaries.

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.

17

Table of Contents

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.

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 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.

ConocoPhillips common stock is traded on the New York Stock Exchange under the trading symbol “COP.” The transfer agent for the common stock is Mellon Investor Services LLC.

Table of Contents

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:

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 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.

Each share of ConocoPhillips Series A preferred stock will be entitled to a minimum preferential quarterly dividend payment per share of the greater of $1 or 100 times the dividend declared per share of ConocoPhillips common stock. In the event of the liquidation, dissolution or winding up of ConocoPhillips, the holders of ConocoPhillips Series A preferred stock will be entitled to a minimum preferential liquidation payment per share equal to the greater of $100 (plus all accrued and unpaid dividends) or 100 times the liquidation payment made per share of ConocoPhillips common stock. Each share of ConocoPhillips Series A preferred stock will have 100 votes on all matters submitted to a vote of ConocoPhillips stockholders, voting together with the ConocoPhillips common stock. In the event of any merger, consolidation or other transaction in which shares of ConocoPhillips

19

Table of Contents

common stock are exchanged for securities, cash and/or any other property, each share of ConocoPhillips Series A preferred stock will be entitled to receive 100 times the amount of securities, cash and/or other properties received per share of ConocoPhillips common stock. These rights will be protected by customary antidilution provisions.

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:

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:

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.

20

Table of Contents

Advance Notice Procedure for Director Nominations and Stockholder Proposals

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.

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:

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 to 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 case 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

21

Table of Contents

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:

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:

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.

DESCRIPTION OF WARRANTS

ConocoPhillips may issue warrants to purchase any combination of debt securities, common stock, preferred stock, rights or other securities of ConocoPhillips or any other entity. ConocoPhillips may issue warrants independently or together with other securities. Warrants sold with other securities may be attached to or separate from the other securities. ConocoPhillips will issue warrants under one or more warrant agreements between it and a warrant agent that we will name in the prospectus supplement.

The prospectus supplement relating to any warrants ConocoPhillips is offering will include specific terms relating to the offering. We will file the form of any warrant agreement with the SEC, and you should read the warrant agreement for provisions that may be important to you. The prospectus supplement will include some or all of the following terms:

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.

23

Table of Contents

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 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:

24

Table of Contents

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:

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:

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.

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.

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 a range of

25

Table of Contents

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 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:

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.

DESCRIPTION OF THE TRUST PREFERRED SECURITIES

Trust Preferred Securities

General

Each ConocoPhillips trust may issue only one series of trust preferred securities. The amended and restated declaration of trust of each trust will authorize that trust to issue one series of trust preferred securities of that trust. We have summarized selected provisions of the trust preferred securities below. This summary is not complete. We have filed the form of amended and restated declaration of trust providing for the trust preferred securities with the SEC as an exhibit to the registration statement, and you should read that document for provisions that may be important to you. Please read “About the ConocoPhillips Trusts” for additional information about the trusts.

The prospectus supplement relating to trust preferred securities being offered will include specific terms relating to the offering. These terms will include some or all of the following:

26

Table of Contents

We also will describe in the prospectus supplement the material United States federal income tax considerations applicable to any offering of trust preferred securities.

ConocoPhillips will guarantee the trust preferred securities to the extent described under “Description of the Preferred Securities Guarantees.”

Voting

Holders of trust preferred securities will have limited voting rights, relating only to the modification of the trust preferred securities and the exercise of a trust’s rights as holder of the debt securities and the preferred securities guarantee. Holders of trust preferred securities will not be able to appoint, remove or replace trustees, except in limited circumstances, or to increase or decrease the number of trustees, because these rights will be vested in the holder of the common securities of the trust. ConocoPhillips will own, directly or indirectly, all of the common securities of each trust.

Distributions

Under each declaration of trust, the property trustee must make distributions on the trust preferred securities of a trust to the extent that the property trustee has cash on hand in the applicable property account to permit such payment. The only funds available for distribution to the holders of the trust preferred securities of a trust will be those received by the property trustee on the debt securities held by the trust. If ConocoPhillips does not make payments on the debt securities, the property trustee will not make corresponding distributions on the trust preferred securities. Under each declaration of trust, if and to the extent ConocoPhillips does make payments on the debt securities, the property trustee will be obligated to make distributions on the preferred and common securities of such trust on a pro rata basis.

ConocoPhillips will guarantee payment of distributions on the trust preferred securities of a trust as and to the extent described under “— Trust Preferred Securities Guarantees.” A guarantee covers distributions and other payments on the applicable trust preferred securities only if and to the extent that ConocoPhillips has made a payment to the property trustee on the applicable debt securities. If an event of default under the related declaration of trust has occurred and is continuing, any funds available to make payments will be paid first to the holders of the trust preferred securities pro rata based on the aggregate liquidation amount of trust preferred securities held by those holders in relation to the aggregate liquidation amount of all the outstanding trust preferred securities. In that case, the holder of common securities of a trust would receive payments only after satisfaction of all amounts owed to the holders of trust preferred securities.

27

Table of Contents

Events of Default

If an event of default under the declaration of trust has occurred and is continuing, the holders of a majority in liquidation amount of the trust preferred securities may direct the property trustee to enforce the available rights under the related declaration of trust, including rights available to the property trustee as a holder of the applicable series of debt securities. If the property trustee fails to enforce those rights, any holder of the related trust preferred securities may provide written notice to the property trustee that the holder will enforce those rights and, 30 days after submitting that request, the holder may enforce those rights directly against ConocoPhillips to the fullest extent permitted by law without first instituting any legal proceeding against the property trustee or any other person.

If an event of default under the applicable declaration of trust has occurred and is continuing and results from ConocoPhillips’ failure to make payments on the applicable series of debt securities when due, then any holder of the trust preferred securities may directly institute a proceeding to enforce those payments on the debt securities in an amount corresponding to the aggregate liquidation amount of that holder’s trust preferred securities. If a holder brings a direct action, ConocoPhillips will be entitled to that holder’s rights under the applicable declaration of trust to the extent of any payment made by ConocoPhillips to that holder. Except as expressly provided in the preceding sentences or in the applicable prospectus supplement, the holders of the trust preferred securities will not be able to exercise directly any other remedy available to the holders of the applicable series of debt securities.

Trust Preferred Securities Guarantees

ConocoPhillips will fully and unconditionally guarantee payments on the trust preferred securities as described in this section. These guarantees cover the following payments:

ConocoPhillips will appoint The Bank of New York Mellon Trust Company, N.A., as guarantee trustee, to hold the guarantee for the benefit of the holders of trust preferred securities. We have summarized selected provisions of the guarantees below. This summary is not complete. We have filed the form of guarantee with the SEC as an exhibit to the registration statement, and you should read that document for provisions that may be important to you.

ConocoPhillips will irrevocably and unconditionally agree to pay holders of trust preferred securities in full the following amounts to the extent not paid by the trust:

ConocoPhillips will not be required to make these liquidation payments if:

28

Table of Contents

ConocoPhillips may satisfy its obligation to make a guarantee payment either by making payment directly to the holders of trust preferred securities or to the guarantee trustee for remittance to the holders or by causing the applicable trust to make the payment to them.

Each guarantee is a guarantee from the time of issuance of the applicable series of trust preferred securities. The guarantee only covers, however, distributions and other payments on trust preferred securities if and to the extent that ConocoPhillips has made corresponding payments on the debt securities to the applicable property trustee. If ConocoPhillips does not make those corresponding payments on the debt securities, the trust will not have funds available for payments and that trustee will not make distributions on the trust preferred securities.

ConocoPhillips’ obligations under the declaration of trust for each trust, the guarantees, the debt securities and the associated indenture taken together will provide a full and unconditional guarantee of payments due on the trust preferred securities.

Covenants of ConocoPhillips

In each guarantee, ConocoPhillips will agree that, as long as any trust preferred securities issued by the applicable trust are outstanding, ConocoPhillips will not make the payments and distributions described below if:

In these circumstances, ConocoPhillips will agree that it will not:

In addition, as long as trust preferred securities issued by any trust are outstanding, ConocoPhillips will agree that it will:

Amendments and Assignment

ConocoPhillips and the guarantee trustee may amend each guarantee without the consent of any holder of trust preferred securities if the amendment does not adversely affect the rights of the holders in any material respect. In all other cases, ConocoPhillips and the guarantee trustee may amend each guarantee only with the prior approval of the holders of a majority in liquidation amount of the trust preferred securities issued by the applicable trust. The manner in which ConocoPhillips will obtain that approval will be described in the prospectus supplement.

ConocoPhillips may assign its obligations under the guarantees only in connection with a consolidation, merger or asset sale involving ConocoPhillips permitted under the indenture governing the debt securities.

Termination of the Guarantee

Each guarantee will terminate upon:

Each guarantee will, however, continue to be effective or will be reinstated if any holder of trust preferred securities must repay any amounts paid on those trust preferred securities or under the guarantee.

Status of the Guarantee

ConocoPhillips’ obligations under each guarantee will be unsecured and effectively junior to all debt and preferred stock of its subsidiaries. We will specify in the prospectus supplement the ranking of each guarantee with respect to ConocoPhillips’ capital stock and other liabilities, including other guarantees. By your acceptance of the trust preferred securities, you agree to any subordination provisions and other terms of the related guarantee.

Each guarantee will be deposited with the guarantee trustee to be held for the benefit of the holders of the trust preferred securities. The guarantee trustee will have the right to enforce the guarantee on behalf of those holders. In most cases, the holders of a majority in liquidation amount of the trust preferred securities issued by the applicable trust will have the right to direct the time, method and place of:

Each guarantee will constitute a guarantee of payment and not merely of collection. This means that the guarantee trustee may institute a legal proceeding directly against ConocoPhillips to enforce the payment rights under the guarantee without first instituting a legal proceeding against any other person or entity.

Table of Contents

If the guarantee trustee fails to enforce the guarantee or ConocoPhillips fails to make a guarantee payment, a holder of trust preferred securities may institute a legal proceeding directly against ConocoPhillips to enforce that holder’s rights under that guarantee without first instituting a legal proceeding against the applicable trust, the guarantee trustee or any other person or entity.

Periodic Reports Under Guarantee

ConocoPhillips will be required to provide annually to the guarantee trustee a statement as to its performance of its obligations and its compliance with all conditions under the guarantees.

Duties of Guarantee Trustee

The guarantee trustee normally will perform only those duties specifically set forth in the applicable guarantee. The guarantee does not contain any implied covenants. If a default occurs on a guarantee, the guarantee trustee will be required to use the same degree of care and skill in the exercise of its powers under the guarantee as a prudent person would exercise or use under the circumstances in the conduct of that person’s own affairs. The guarantee trustee will exercise any of its rights or powers under the guarantee at the request or direction of holders of the applicable series of trust preferred securities only if it is offered security and indemnity satisfactory to it.

Governing Law

New York law will govern the guarantees.

Relationship Among the Trust Preferred Securities, Debt Securities and Trust Preferred Securities Guarantee

When taken together, the terms of the trust preferred securities of a ConocoPhillips trust, the debt securities held by that trust and the related preferred securities guarantee provide a full and unconditional guarantee by ConocoPhillips of the payments due on the trust preferred securities. The following summary briefly explains the interrelationship between the trust preferred securities, the debt securities and the guarantee.

The trust will be able to make payments on the trust preferred securities only if ConocoPhillips makes payments on the debt securities.

As long as ConocoPhillips makes interest and other payments when due on the debt securities, the trust will have sufficient funds to make distribution and other payments when due on the trust preferred securities for the following reasons:

31

Table of Contents

ConocoPhillips will guarantee that payments will be made on the trust preferred securities if ConocoPhillips makes payments on the debt securities.

If ConocoPhillips makes interest or other payments on the debt securities, the property trustee will be obligated to make corresponding distribution or other payments on the trust preferred securities. ConocoPhillips will guarantee such payments if the trust fails to make them. The guarantee only covers distributions and other payments on the trust preferred securities if and to the extent ConocoPhillips has made corresponding payments on the debt securities. The guarantee trustee will have the right to enforce the guarantee on behalf of the holders of the trust preferred securities if ConocoPhillips fails to make any required guarantee payments. If the guarantee trustee fails to enforce the guarantee, you may institute a legal proceeding directly against ConocoPhillips to enforce the guarantee trustee’s rights under the guarantee. If ConocoPhillips fails to make a guarantee payment, you may also institute a legal proceeding directly against ConocoPhillips to enforce the guarantee.

The property trustee may institute legal proceedings against ConocoPhillips if ConocoPhillips fails to make payments on the debt securities.

If ConocoPhillips does not make interest or other payments on the debt securities, the trust will not have funds available to make the corresponding distribution or other payments on the trust preferred securities. The property trustee, as the holder of the debt securities, will have the right to enforce ConocoPhillips’ obligations on the debt securities if an event of default under the debt securities occurs. In addition, the holders of a majority in liquidation amount of the trust preferred securities will have the right to direct the property trustee with respect to certain matters under the declaration of trust. If the property trustee fails to enforce its rights, any holder of trust preferred securities may, to the fullest extent permitted by law and after a period of 30 days has elapsed from such holder’s written request to the property trustee to enforce such rights, institute a legal proceeding against ConocoPhillips to enforce such rights.

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 reallowed 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

32

Table of Contents

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 of 1933 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.

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 of 1933 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.

General Information

We may have agreements with the agents, dealers and underwriters to indemnify them against civil liabilities, including liabilities under the Securities Act of 1933, 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.

Item 15. Indemnification of Directors and Officers

ConocoPhillips and ConocoPhillips Company

Delaware law permits a corporation to adopt a provision in its certificate of incorporation eliminating or limiting the personal liability of a director, but not an officer in his or her capacity as such, to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except that such provision shall not limit the liability of a director for (1) any breach of the director’s duty of loyalty to the corporation or its stockholders, (2) acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law, (3) liability under section 174 of the Delaware General Corporation Law for unlawful payment of dividends or stock purchases or redemptions, or (4) any transaction from which the director derived an improper personal benefit. ConocoPhillips’ amended and restated certificate of incorporation provides that, to the fullest extent of Delaware law, no ConocoPhillips director shall be liable to ConocoPhillips or ConocoPhillips stockholders for monetary damages for breach of fiduciary duty as a director. The certificate of incorporation of ConocoPhillips Company (“CPCo”) has similar provisions with respect to its directors.

Under Delaware law, a corporation may indemnify any individual made a party or threatened to be made a party to any type of proceeding, other than an action by or in the right of the corporation, because he or she is or was an officer, director, employee or agent of the corporation or was serving at the request of the corporation as an officer, director, employee or agent of another corporation or entity against expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred in connection with such proceeding: (1) if he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation; or (2) in the case of a criminal proceeding, he or she had no reasonable cause to believe that his or her conduct was unlawful. A corporation may indemnify any individual made a party or threatened to be made a party to any threatened, pending or completed action or suit brought by or in the right of the corporation because he or she was an officer, director, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or other entity, against

II-1

Table of Contents

expenses actually and reasonably incurred in connection with such action or suit if he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation, provided that such indemnification will be denied if the individual is found liable to the corporation unless, in such a case, the court determines the person is nonetheless entitled to indemnification for such expenses. A corporation must indemnify a present or former director or officer who successfully defends himself or herself in a proceeding to which he or she was a party because he or she was a director or officer of the corporation against expenses actually and reasonably incurred by him or her. Expenses incurred by an officer or director, or any employees or agents as deemed appropriate by the board of directors, in defending civil or criminal proceedings may be paid by the corporation in advance of the final disposition of such proceedings upon receipt of an undertaking by or on behalf of such director, officer, employee or agent to repay such amount if it shall ultimately be determined that he or she is not entitled to be indemnified by the corporation. The Delaware law regarding indemnification and expense advancement is not exclusive of any other rights which may be granted by ConocoPhillips’ amended and restated certificate of incorporation or bylaws, a vote of stockholders or disinterested directors, agreement or otherwise.

Under the Delaware General Corporation Law, termination of any proceeding by conviction or upon a plea of nolo contendere or its equivalent shall not, of itself, create a presumption that such person is prohibited from being indemnified.

ConocoPhillips’ bylaws provide for the indemnification and advancement of expenses of any individual made, or threatened to be made, a party to an action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that he or she is or was a director or officer of ConocoPhillips or is or was a director or officer of ConocoPhillips serving as an officer, director, employee or agent of any other enterprise at the request of ConocoPhillips to the fullest extent permitted under applicable law. CPCo’s bylaws have similar provisions. However, neither ConocoPhillips nor CPCo will indemnify a director or officer who commences any proceeding (except for proceedings to enforce rights of indemnification), unless the commencement of that proceeding was authorized or consented to by the respective company’s board of directors.

ConocoPhillips Trusts

Prior to the issuance of trust preferred securities by a ConocoPhillips trust, the existing declaration of trust pursuant to which such trust is created will be amended and restated to provide that no trustee, or affiliate of any trustee, or paying agent, officer, director, shareholder, member, partner, employee, representative or agent of any trustee or paying agent, or employee or agent of such trust or of any of its affiliates (each, an “Indemnified Person”) will be liable for any loss, damage or claim incurred by reason of any act or omission performed or omitted by such Indemnified Person in good faith on behalf of such trust and in a manner such Indemnified Person reasonably believed to be within the scope of the authority conferred on such Indemnified Person by such amended and restated declaration of trust or by law, except that an Indemnified Person shall be liable for any such loss, damage or claim incurred by reason of such Indemnified Person’s gross negligence (or, in the case of the property trustee of such trust, negligence) or willful misconduct with respect to such acts or omissions.

In addition, such amended and restated declaration of trust shall provide that, to the fullest extent permitted by applicable law, ConocoPhillips shall indemnify and hold harmless each Indemnified Person from and against any loss, liability, expense, damage or claim incurred by such Indemnified Person arising out of or in connection with the acceptance or administration of the trust under such declaration of trust or by reason of any act or omission performed or omitted by such Indemnified Person in good faith on behalf of such trust and in a manner such Indemnified Person reasonably believed to be within the scope of authority conferred on such Indemnified Person by such declaration of trust, except that no Indemnified Person shall be entitled to be indemnified in respect of any loss, liability, expense, damage or claim incurred by such Indemnified Person by reason of gross negligence (or, in the case of the property trustee of the trust, negligence) or willful misconduct with respect to such acts or omissions.

Item 17. Undertakings

(a) The undersigned Registrants hereby undertake:

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

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

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

provided, however , that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) of this section do not apply if the registration statement is on Form S-3 and the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act, that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

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

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

(4) That, for the purpose of determining liability under the Securities Act to any purchaser:

(A) Each prospectus filed by a Registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

II-5

Table of Contents

(B) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii) or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(5) That, for the purpose of determining liability of a Registrant under the Securities Act to any purchaser in the initial distribution of the securities:

Each undersigned Registrant undertakes that in a primary offering of securities of such undersigned Registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, such undersigned Registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) Any preliminary prospectus or prospectus of such undersigned Registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of such undersigned Registrant or used or referred to by such undersigned Registrant;

(iii) The portion of any other free writing prospectus relating to the offering containing material information about such undersigned Registrant or its securities provided by or on behalf of such undersigned Registrant; and

(iv) Any other communication that is an offer in the offering made by such undersigned Registrant to the purchaser.

(b) The undersigned Registrants hereby further undertake that, for purposes of determining any liability under the Securities Act, each filing of a Registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

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