S-2

USE OF PROCEEDS

The selling stockholders will receive all of the proceeds from the sale or other disposition of the shares of Common Stock covered by this prospectus supplement. We will not receive any of the proceeds from the sale or other disposition of the shares of Common Stock offered hereby.

S-3

SELLING STOCKHOLDERS

The shares of our Common Stock that we are registering for resale on behalf of the selling stockholders in this prospectus supplement were issued to the selling stockholders in connection with the Grayson Mill Acquisition.

We will pay certain expenses of the registration of the shares offered hereby, including the SEC filing fees. Brokerage commissions and similar selling expenses, if any, attributable to the sale of the shares will be borne by the selling stockholders. In addition, pursuant to the Registration Rights Agreement, we have agreed to indemnify the selling stockholders and certain of their affiliates against certain liabilities in connection with the offering of the shares.

The following table sets forth, to our knowledge, certain information about the selling stockholders. We have not sought to verify such information. The percentage of outstanding shares of our Common Stock beneficially owned by the selling stockholders prior to the offering is based on 658,259,031 shares of our Common Stock outstanding as of September 30, 2024. The selling stockholders may hold or acquire at any time shares of our Common Stock in addition to those offered by this prospectus supplement and may have acquired additional shares since the date on which the information reflected herein was provided to us. Additionally, the selling stockholders may have sold, transferred or otherwise disposed of some or all of the shares of our Common Stock listed below in exempt or non-exempt transactions since the date on which the information was provided to us and may in the future sell, transfer or otherwise dispose of some or all of the shares in private placement transactions exempt from, or not subject to the registration requirements of, the Securities Act.

Information about the selling stockholders may change from time to time. Any changed information will be set forth in prospectus supplements, if required by applicable law. For information on the procedure for sales by the selling stockholders, see “Plan of Distribution” in this prospectus supplement.

S-5

PLAN OF DISTRIBUTION

The selling stockholders may sell the securities from time to time on any stock exchange or automated interdealer quotation system on which the securities are traded, in the over-the-counter market, in privately-negotiated transactions or otherwise, at fixed prices that may be changed, at market prices prevailing at the time of sale, at prices related to prevailing market prices or at prices otherwise negotiated. The selling stockholders may act independently of us in making decisions with respect to the timing, manner and size of each of their sales. The selling stockholders may, from time to time, sell, distribute or otherwise transfer the securities by one or more of the following methods, without limitation:

The selling stockholders may also distribute any or all of the securities covered by this prospectus supplement to their general or limited partners, members, managers, affiliates, employees, directors, stockholders or other direct or indirect successor-in-interest (“distributee”) to the selling stockholder who may from time to time effect sales or other distributions of the securities.

In the event that any such distributee receives any such shares in such a distribution or other non-sale-related transfer after the date of this prospectus supplement, such distributee may offer, sell, distribute or otherwise transfer such shares under this prospectus supplement and, in doing so, will be the “selling stockholders” for purposes of this prospectus supplement.

The selling stockholders may engage underwriters, brokers or dealers, and any underwriters, brokers or dealers may arrange for other underwriters, brokers or dealers to participate in effecting sales of the securities.

S-6

These brokers, dealers or underwriters may act as principals, or as an agent of the selling stockholders. Broker-dealers may agree with the selling stockholders to sell a specified number of the securities at a stipulated price per security. If the broker-dealer is unable to sell securities acting as agent for the selling stockholders, it may purchase as principal any unsold securities at the stipulated price. Broker-dealers who acquire securities as principals may thereafter resell the securities from time to time in transactions in any stock exchange or automated interdealer quotation system on which the securities are then listed or in over-the-counter market, at prices and on terms then prevailing at the time of sale, at prices related to the then-current market price or in negotiated transactions. Broker-dealers may use block transactions and sales to and through broker-dealers, including transactions of the nature described above. The selling stockholders may also sell the securities in accordance with Section 4(a)(1) of the Securities Act and in accordance with Rule 144 under the Securities Act, rather than pursuant to this prospectus supplement, regardless of whether the securities are covered by this prospectus supplement.

In addition, selling stockholders may, from time to time, sell the securities short or enter into derivative or hedging transactions with third parties, and, in those instances, this prospectus supplement and the accompanying prospectus may be delivered in connection with these transactions and the securities offered under this prospectus supplement may be used to cover short sales or close out any related positions resulting from these transactions.

The selling stockholders may also enter into derivative or hedging transactions with broker-dealers and the broker-dealers may engage in short sales of the securities in the course of hedging the positions they assume with the selling stockholders, including, without limitation, in connection with distributions of the securities by those broker-dealers. The selling stockholders may enter into options or other transactions with broker-dealers that involve the delivery of the securities offered hereby to the broker-dealers, who may then resell or otherwise transfer those securities. The selling stockholders may also loan or pledge the securities offered hereby to a broker-dealer and the broker-dealer may sell the securities offered hereby so loaned or upon a default may sell or otherwise transfer the pledged securities offered hereby.

To the extent required under the Securities Act, the aggregate amount of the selling stockholders’ securities being offered and the terms of the offering, the names of any agents, brokers, dealers or underwriters and any applicable commission with respect to a particular offer will be set forth in an accompanying prospectus supplement. Any underwriters, dealers, brokers or agents participating in the distribution of the securities may receive compensation in the form of underwriting discounts, concessions, commissions or fees from the selling stockholders and/or purchasers of the selling stockholders’ securities, for whom they may act (which compensation as to a particular broker-dealer might be in excess of customary commissions). To the extent the securities offered pursuant to a prospectus supplement remain unsold, the selling stockholders may offer those securities on different terms pursuant to another prospectus supplement. The selling stockholders and any underwriters, brokers, dealers or agents that participate in the distribution of the securities may be deemed to be “underwriters” within the meaning of the Securities Act, and any discounts, concessions, commissions or fees received by them and any profit on the resale of the securities sold by them may be deemed to be underwriting discounts and commissions.

A Delaware corporation formed in 1971 and publicly held since 1988, Devon is an independent energy company engaged primarily in the exploration, development and production of oil, natural gas and natural gas liquids. Our operations are concentrated in various onshore areas in the U.S.

WPX was an oil and gas exploration and production company with assets in the Delaware Basin in Texas and New Mexico and the Williston Basin in North Dakota.

In accordance with the Agreement and Plan of Merger, dated September 26, 2020, by and among Devon, East Merger Sub, Inc. and WPX, WPX shareholders received a fixed exchange of .5165 shares of our common stock for each share of WPX common stock owned.

RISK FACTORS

Investing in our securities involves a high degree of risk. Before making an investment decision and acquiring any offered securities pursuant to this prospectus, you should carefully consider the information contained or incorporated by reference in this prospectus and in any accompanying prospectus supplement, including, without limitation, the risks described in our most recent Annual Report on Form 10-K for the fiscal year ended December 31, 2022, as may be amended or supplemented by our Quarterly Reports on Form 10-Q, which are incorporated herein by reference, the risk factors described under the caption “Risk Factors” in any applicable prospectus supplement and any risk factors set forth in our other filings with the SEC pursuant to Sections 13(a), 13(c), 14 or 15(d) of the Exchange Act. The occurrence of any of these risks might cause you to lose all or a part of your investment in the offered securities. See “Where You Can Find More Information.”

USE OF PROCEEDS

Unless otherwise indicated in an accompanying prospectus supplement, we expect to use the net proceeds from the sale of the securities offered by this prospectus for general corporate purposes, which may include but are not limited to, among other things:

The precise amount and timing of the application of such proceeds will depend upon our funding requirements and the availability and cost of other funds. Pending any specific application, we may initially invest funds in short-term marketable securities or money-market investments, as well as apply them to the reduction of short-term indebtedness.

DESCRIPTION OF CAPITAL STOCK

General

Devon’s authorized capital stock consists of:

As of February 1, 2023, there were 653,984,535 shares of common stock outstanding and no shares of preferred stock outstanding.

Common Stock

Holders of common stock will be entitled to receive dividends out of legally available funds when and if declared by our board of directors. Subject to the rights of the holders of any outstanding shares of preferred stock, holders of shares of common stock will be entitled to cast one vote for each share held of record on all matters submitted to a vote of stockholders. They will not be entitled to cumulative voting rights for the election of directors. The shares of common stock have no preemptive, conversion or other rights to subscribe for or purchase any of our securities. Upon our liquidation or dissolution, the holders of shares of common stock are entitled to share ratably in any of our assets that remain after payment or provision for payment to creditors and holders of preferred stock.

Preferred Stock

The preferred stock may be issued in one or more series. Our board of directors may establish attributes of any series, including the designation and number of shares in the series, dividend rates (cumulative or noncumulative), voting rights, redemptions, conversion or preference rights and any other rights and qualifications, preferences and limitations or restrictions on shares of a series. The issuance of preferred stock may have the effect of delaying, deferring or preventing a change in control of Devon without any vote or action by the stockholders and may adversely affect the voting and other rights of the holders of shares of common stock. The specific terms of a particular series of preferred stock will be described in a certificate of designation relating to that series.

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

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

5

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

Certain Anti-Takeover Matters

Our restated certificate of incorporation and our amended and restated bylaws contain provisions that may make it more difficult for a potential acquirer to acquire us by means of a transaction that is not negotiated with our board of directors. These provisions and certain provisions of the General Corporation Law of the State of Delaware, or the “DGCL,” could delay or prevent a merger or acquisition that our stockholders consider favorable. These provisions may also discourage acquisition proposals or have the effect of delaying or preventing a change in control, which could harm our stock price. Following is a description of the anti-takeover effects of certain provisions of our restated certificate of incorporation and our amended and restated bylaws.

No cumulative voting. The DGCL provides that stockholders of a Delaware corporation are not entitled to the right to cumulate votes in the election of directors unless its certificate of incorporation provides otherwise. Our restated certificate of incorporation provides that cumulative voting is not permitted.

Calling of special meetings of stockholders. Our amended and restated bylaws provide that special meetings of our stockholders may be called only by or at the direction of our board of directors, the chairman of our board of directors, our president or by our secretary upon an appropriately made written request of one or more record holders owning, and having held continuously for a period of at least one year prior to the date such request is delivered, an aggregate of not less than 25% of the voting power of all outstanding shares of our capital stock.

Advance notice requirements for stockholder proposals and director nominations. Our amended and restated bylaws provide that stockholders seeking to nominate candidates for election as directors or to bring business before an annual meeting of stockholders or a stockholder requested special meeting of stockholders must provide timely notice of their proposal in writing to our corporate secretary.

Generally, to be timely, a stockholder’s notice regarding an annual meeting of stockholders must be received at our principal executive offices not less than 90 days nor more than 120 days prior to the first anniversary of the previous year’s annual meeting. Our amended and restated bylaws also specify requirements as to the form and content of a stockholder’s notice. These provisions may impede stockholders’ ability to bring matters before an annual meeting of stockholders, a stockholder requested special meeting of stockholders or make nominations for directors.

6

No action by stockholder consent. Our restated certificate of incorporation provides that any action required or permitted to be taken by the stockholders of Devon must be effected at a duly called annual or special meeting of Devon’s stockholders, and specifically denies to the stockholders the ability to consent in writing to the taking of any action.

Limitations on liability and indemnification of officers and directors. The DGCL authorizes corporations to limit or eliminate the personal liability of directors to corporations and their stockholders for monetary damages for breaches of directors’ fiduciary duties. Our restated certificate of incorporation provides that directors shall not be liable to the corporation or our stockholders for monetary damages for breach of fiduciary duty, except to the extent such exemption from liability or limitation thereof is not permitted under the DGCL as the same exists or may hereafter be amended.

Our restated certificate of incorporation and amended and restated bylaws require us to indemnify our directors, officers, employees and agents in certain circumstances and also authorize us to carry directors’ and officers’ insurance for the benefit of our directors, officers, employees and agents. We believe that these indemnification provisions and insurance are useful to attract and retain qualified directors and officers.

The limitation of liability and indemnification provisions in our restated certificate of incorporation and amended and restated bylaws may discourage our stockholders from bringing lawsuits against directors for breach of their fiduciary duty. These provisions may also have the effect of reducing the likelihood of derivative litigation against directors and officers, even though such an action, if successful, might otherwise benefit us and our stockholders. In addition, a stockholder’s investment may be adversely affected to the extent we pay the costs of settlement and damage awards against directors and officers pursuant to these indemnification provisions.

Board authority to amend bylaws. Under our restated certificate of incorporation and our amended and restated bylaws, our board of directors has the authority to adopt, amend or repeal our bylaws without the approval of our stockholders. However, our stockholders also have the right, with the affirmative vote of the holders of at least a majority of the combined voting power of the then-outstanding shares of voting stock and without the approval of our board of directors, to adopt, amend or repeal our bylaws.

General Corporation Law of the State of Delaware. Devon is a Delaware corporation that is subject to Section 203 of the DGCL. Section 203 provides that, subject to certain exceptions specified therein, a Delaware corporation shall not engage in certain “business combinations” with any “interested stockholder” for a three-year period following the time that the stockholder became an interested stockholder unless:

Generally, a “business combination” includes a merger, asset or stock sale or other transaction that results in a financial benefit to the interested stockholder. Subject to certain exceptions, an “interested stockholder” is a person who, together with that person’s affiliates and associates, owns, or within the previous three years did own, 15% or more of our voting stock.

Under certain circumstances, Section 203 could make it more difficult for a person who would be an “interested stockholder” to effect a “business combination” with Devon. Section 203 of the DGCL may

7

encourage any person interested in acquiring Devon to negotiate in advance with our board of directors because the stockholder approval requirement would be avoided if our board of directors approves either the business combination or the transaction that results in such person becoming an interested stockholder. Section 203 of the DGCL also may make it more difficult to effect transactions involving our Company that our stockholders may otherwise deem to be in their best interests.

Listing

Our common stock is listed and traded on the New York Stock Exchange under the symbol “DVN.”

Transfer Agent and Registrar

The transfer agent and registrar for our common stock is Computershare Trust Company, N.A. Its address is c/o Computershare Investor Services, P.O. Box 43078, Providence, RI 02940-3078 and its telephone number is (877) 860-5820.

DESCRIPTION OF DEPOSITARY SHARES

General

We may choose to offer fractional shares or some multiple of shares of our preferred stock, rather than whole individual shares. If we decide to do so, we will issue the preferred stock in the form of depositary shares. Each depositary share would represent a fraction or multiple of a share of the preferred stock and would be evidenced by a depositary receipt.

Deposit Agreement

We will deposit the shares of preferred stock to be represented by depositary shares under a deposit agreement. The parties to the deposit agreement will be:

Each holder of a depositary share will be entitled to all the rights and preferences of the underlying preferred stock, including, where applicable, dividend, voting, redemption, conversion and liquidation rights, in proportion to the applicable fraction or multiple of a share of preferred stock represented by the depositary share. The depositary shares will be evidenced by depositary receipts issued under the deposit agreement. The depositary receipts will be distributed to those persons purchasing the fractional or multiple shares of preferred stock. A depositary receipt may evidence any number of whole depositary shares.

We will file the deposit agreement, including the form of depositary receipt, with the SEC, either as an exhibit to an amendment to the registration statement of which this prospectus forms a part or as an exhibit to a current report on Form 8-K. See “Where You Can Find More Information” below for information on how to obtain a copy of the form of deposit agreement.

Dividends and Other Distributions

The preferred stock depositary will distribute any cash dividends or other cash distributions received in respect of the deposited preferred stock to the record holders of depositary shares relating to the underlying preferred stock in proportion to the number of depositary shares owned by the holders. The preferred stock depositary will distribute any property received by it other than cash to the record holders of depositary shares entitled to those distributions, unless it determines that the distribution cannot be made proportionally among those holders or that it is not feasible to make a distribution. In that event, the preferred stock depositary may, with our approval, sell the property and distribute the net proceeds from the sale to the holders of the depositary shares in proportion to the number of depositary shares they own.

The amounts distributed to holders of depositary shares will be reduced by any amounts required to be withheld by the preferred stock depositary or by us on account of taxes or other governmental charges.

Withdrawal of Preferred Stock

Any holder of depositary shares may receive the number of whole shares of the related series of preferred stock and any money or other property represented by those depositary receipts after surrendering the depositary receipts at the corporate trust office of the preferred stock depositary, paying any taxes, charges and fees provided for in the deposit agreement and complying with any other requirement of the deposit agreement. Holders of depositary shares making these withdrawals will be entitled to receive whole shares of preferred

9

stock, but holders of whole shares of preferred stock will not be entitled to deposit that preferred stock under the deposit agreement or to receive depositary receipts for that preferred stock after withdrawal. If the depositary shares surrendered by the holder in connection with withdrawal exceed the number of depositary shares that represent the number of whole shares of preferred stock to be withdrawn, the preferred stock depositary will deliver to that holder at the same time a new depositary receipt evidencing the excess number of depositary shares.

Voting Deposited Preferred Stock

When the preferred stock depositary receives notice of any meeting at which the holders of any series of deposited preferred stock are entitled to vote, the preferred stock depositary will mail the information contained in the notice to the record holders of the depositary shares relating to the applicable series of preferred stock. Each record holder of the depositary shares on the record date, which will be the same date as the record date for the preferred stock, may instruct the preferred stock depositary to vote the amount of the preferred stock represented by the holder’s depositary shares. To the extent possible, the preferred stock depositary will vote the amount of the series of preferred stock represented by depositary shares in accordance with the instructions it receives. We will agree to take all reasonable actions that the preferred stock depositary determines are necessary to enable the preferred stock depositary to vote as instructed. If the preferred stock depositary does not receive specific instructions from the holders of any depositary shares representing a series of preferred stock, it will vote all shares of that series held by it proportionately with instructions received.

Conversion of Preferred Stock

If the prospectus supplement relating to the depositary shares says that the deposited preferred stock is convertible into or exercisable or exchangeable for common stock, preferred stock of another series or other securities of Devon, the following will apply. The depositary shares, as such, will not be convertible into or exercisable or exchangeable for any securities of Devon. Rather, any holder of the depositary shares may surrender the related depositary receipts to the preferred stock depositary with written instructions to instruct us to cause conversion, exercise or exchange of the preferred stock represented by the depositary shares into or for whole shares of common stock, shares of another series of preferred stock or other securities of Devon. Upon receipt of those instructions and any amounts payable by the holder in connection with the conversion, exercise or exchange, we will cause the conversion, exercise or exchange using the same procedures as those provided for conversion, exercise or exchange of the deposited preferred stock. If only some of the depositary shares are to be converted, exercised or exchanged, a new depositary receipt or receipts will be issued for any depositary shares not to be converted, exercised or exchanged.

Amendment of the Deposit Agreement

We may amend the form of depositary receipt evidencing the depositary shares and any provision of the deposit agreement at any time and from time to time by agreement with the preferred stock depositary. However, any amendment that imposes additional charges or materially and adversely alters any substantial existing right of the holders of depositary shares will not be effective unless the holders of at least a majority of the affected depositary shares then outstanding approve the amendment. We will make no amendment that impairs the right of any holder of depositary shares, as described above under “—Withdrawal of Preferred Stock”, to receive shares of the related series of preferred stock and any money or other property represented by those depositary shares, except in order to comply with mandatory provisions of applicable law. Holders who retain or acquire their depositary receipts after an amendment becomes effective will be deemed to have agreed to the amendment and will be bound by the amended deposit agreement.

Charges of Preferred Stock Depositary; Taxes and Other Governmental Charges

We will pay the fees, charges and expenses of the preferred stock depositary provided in the deposit agreement to be payable by us. Holders of depositary receipts will pay any taxes and governmental charges and

10

any charges provided in the deposit agreement to be payable by them, including a fee for the withdrawal of shares of preferred stock upon surrender of depositary receipts. If the preferred stock depositary incurs fees, charges or expenses for which it is not otherwise liable at the election of a holder of a depositary receipt or other person, that holder or other person will be liable for those fees, charges and expenses.

Resignation and Removal of Depositary

The preferred stock depositary may resign at any time by giving us notice, and we may remove or replace the preferred stock depositary at any time.

Reports to Holders

We will deliver all required reports and communications to holders of the preferred stock to the preferred stock depositary. It will forward those reports and communications to the holders of depositary shares.

Limitation on Liability of the Preferred Stock Depositary

The preferred stock depositary will not be liable if it is prevented or delayed by law or any circumstances beyond its control in performing its obligations under the deposit agreement. The obligations of the preferred stock depositary under the deposit agreement will be limited to performance in good faith of its duties under the agreement, and it will not be obligated to prosecute or defend any legal proceeding in respect of any depositary shares, depositary receipts or shares of preferred stock unless satisfactory and reasonable protection from expenses and liability is furnished. This is called an indemnity. The preferred stock depositary may rely upon written advice of counsel or accountants, upon information provided by holders of depositary receipts or other persons believed to be competent and upon documents believed to be genuine.

DESCRIPTION OF WARRANTS

The following description of the warrants sets forth certain general terms and provisions of the warrants to which this prospectus and any prospectus supplement may relate. The particular terms of any warrants and the extent to which the general provisions may apply to such warrants will be described in a prospectus supplement relating to such warrants.

We may issue warrants to purchase debt or equity securities. Each warrant will entitle the holder of warrants to purchase for cash or other consideration the amount of debt or equity securities at the exercise price stated or determinable in the prospectus supplement for the warrants. We may issue warrants independently or together with any offered securities. The warrants may be attached to or separate from those offered securities. We will issue the warrants under warrant agreements to be entered into between us and a bank or trust company, as warrant agent, all as described in the applicable prospectus supplement. The warrant agent will act solely as our agent in connection with the warrants and will not assume any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants.

The prospectus supplement relating to any warrants that we may offer will contain the specific terms of the warrants. These terms may include the following:

12

DESCRIPTION OF DEBT SECURITIES

The following description of the debt securities sets forth certain general terms and provisions of the debt securities to which this prospectus and any prospectus supplement may relate. The particular terms of any series of debt securities and the extent to which the general provisions may apply to a particular series of debt securities will be described in a prospectus supplement relating to that series.

Any debt securities offered by this prospectus will be issued under one or more indentures between Devon and a trustee. We have summarized selected provisions of the indentures below. Devon senior debt securities are to be issued under an indenture between Devon and UMB Bank, National Association, as trustee (the “Devon senior indenture”), which is incorporated by reference as an exhibit to the registration statement of which this prospectus forms a part. Devon subordinated debt securities are to be issued under an indenture (the “Devon subordinated indenture”), which is incorporated by reference as an exhibit to the registration statement of which this prospectus forms a part. The Devon senior indenture and the Devon subordinated indenture are sometimes referred to herein, collectively, as the “indentures” and each, individually, as an “indenture.” You should read the indentures for provisions that may be important to you.

Because we have included only a summary of the indenture terms, you must read the indentures in full to understand every detail of the terms of the debt securities.

The indentures will not limit the amount of debt securities we may issue under them, and will provide that additional debt securities of any series may be issued up to the aggregate principal amount that we authorize from time to time.

Unless otherwise indicated in the applicable prospectus supplement, we will issue the debt securities in denominations of $2,000 and in integral multiples of $1,000 in excess thereof.

Principal and any premium and interest in respect of the debt securities will be payable, and the debt securities will be transferable, at the corporate trust office of the trustee, unless we specify otherwise in the applicable prospectus supplement. At our option, however, we may pay interest by mailing checks to the registered holders of the debt securities at their registered addresses.

We will describe any special U.S. federal income tax and other considerations relating to the debt securities in the applicable prospectus supplement.

General

The prospectus supplement relating to the particular series of debt securities being offered will specify the amounts, prices and terms of those debt securities. These terms may include:

13

We are not obligated to issue all debt securities of any one series at the same time. The debt securities of any one series need not bear interest at the same rate or mature on the same date.

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

Except as may be described in the applicable prospectus supplement, the indenture will not limit our ability to incur indebtedness or afford holders of debt securities protection in the event of a decline in our credit quality or if we are involved in a takeover, recapitalization or highly leveraged or similar transaction. The prospectus supplement relating to the particular series of debt securities, to the extent not otherwise described in this prospectus, will include any information with respect to any deletions from, modifications of or additions to the covenants or events of default described below and contained in the indenture, including any addition of a covenant or other provision providing event risk or similar protection.

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

14

Interest Rates and Discounts

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

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

Exchange, Registration and Transfer

Unless otherwise specified, debt securities of any series will be exchangeable for other debt securities of the same series and of like aggregate principal amount and tenor in different authorized denominations.

You may present debt securities for registration of transfer, together with a duly executed form of transfer, at the office of the security registrar or at the office of any transfer agent designated by us for that purpose with respect to any series of debt securities and referred to in the applicable prospectus supplement. This may be done without service charge but upon payment of any taxes and other governmental charges as described in the indenture. The security registrar or the transfer agent will effect the transfer or exchange upon being satisfied with the documents of title and identity of the person making the request. We may at any time designate additional transfer agents with respect to any series of debt securities.

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

Payment and Paying Agents

Unless we specify otherwise in the applicable prospectus supplement, we will pay the principal of, and any premium and interest on, debt securities at the office of the paying agent or paying agents that we designate at various times. However, at our option, we may make interest payments by check mailed to the address, as it appears in the security register, of the person entitled to the payments. Unless we specify otherwise in the applicable prospectus supplement, the Corporate Trust Office of the trustee in Kansas City, Missouri, will be designated as our sole paying agent for payments with respect to debt securities that are issuable solely as registered securities.

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

Global Securities

The debt securities of a series may be issued in whole or in part in the form of one or more global certificates that we will deposit with a depository identified in the applicable prospectus supplement, or a

15

custodian for such depository. Global securities may be issued in either registered or bearer form and in either temporary or permanent form. Unless and until it is exchanged in whole or in part for the individual debt securities it represents, a global security may not be transferred except as a whole:

We will describe the specific terms of the depositary arrangement with respect to a series of debt securities in the applicable prospectus supplement. We anticipate that the following provisions will generally apply to depositary arrangements.

When we issue a global security in registered form, the depositary for the global security or its nominee will credit, on its book-entry registration and transfer system, the respective principal amounts of the individual debt securities represented by that global security to the accounts of participants that have accounts with the depositary. Those accounts will be designated by the dealers, underwriters or agents with respect to the underlying debt securities or by us if those debt securities are offered and sold directly by us. Ownership of beneficial interests in a global security will be limited to participants or persons that may hold interests through participants. For interests of participants, ownership of beneficial interests in the global security will be shown on records maintained by the applicable depositary or its nominee. For interests of persons other than participants, that ownership information will be shown on the records of participants. Transfer of that ownership will be effected only through those records.

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

As long as the depositary for a global security, or its nominee, is the registered owner of that global security, the depositary or nominee will be considered the sole owner or holder of the debt securities represented by the global security for all purposes under the applicable indenture. Except as provided below, owners of beneficial interests in a global security:

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

We expect that the depositary or its nominee, upon receipt of any payment of principal, premium or interest relating to a permanent global security representing any series of debt securities, immediately will credit participants’ accounts with the payments. Those payments will be credited in amounts proportional to the respective beneficial interests of the participants in the principal amount of the global security as shown on the records of the depositary or its nominee. We also expect that payments by participants to owners of beneficial interests in the global security held through those participants will be governed by standing instructions and customary practices. This is now the case with securities held for the accounts of customers in bearer form or registered in “street name.” Those payments will be the sole responsibility of those participants.

16

If the depositary for a series of debt securities is at any time unwilling, unable or ineligible to continue as depositary and we do not appoint a successor depositary within 90 days, we will issue individual debt securities of that series in exchange for the global security or securities representing that series. In addition, we may at any time in our sole discretion determine not to have any debt securities of a series represented by one or more global securities. In that event, we will issue individual debt securities of that series in exchange for the global security or securities. Further, if we specify, an owner of a beneficial interest in a global security may, on terms acceptable to us, the trustee and the applicable depositary, receive individual debt securities of that series in exchange for those beneficial interests. The foregoing is subject to any limitations described in the applicable prospectus supplement. In that instance, the owner of the beneficial interest will be entitled to physical delivery of individual debt securities equal in principal amount to the beneficial interest and to have the debt securities registered in its name. Those individual debt securities will be issued in denominations, unless we specify otherwise, of $2,000 and in integral multiples of $1,000 in excess thereof.

For a description of the depositary arrangements for global securities held by The Depository Trust Company, also known as DTC, see “Book-Entry Securities.”

Events of Default

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

If an event of default occurs because we fail to pay the principal of, or premium or interest on, the debt securities of any series or we fail to perform or breach any of the other covenants or warranties applicable to the debt securities of that series but not applicable to all outstanding debt securities, and such event of default is continuing, either the trustee or the holders of not less than 25% in aggregate principal amount of the outstanding debt securities of that series may declare the principal amount of, and any premium and interest on, the debt securities of that series to be due and payable immediately. If an event of default occurs due to default in the performance of any other of the covenants and warranties applicable to all outstanding debt securities or pertaining to certain events of bankruptcy, insolvency or reorganization, and the event of default is continuing, either the trustee or the holders of not less than 25% in principal amount of all debt securities then outstanding (considered as one class), may declare the principal amount of, and any premium and interest on, all debt securities to be due and payable immediately. There is no automatic acceleration, even in the event of our bankruptcy, insolvency or reorganization. At any time after a declaration of acceleration has been made, but before a judgment or decree for payment of money has been obtained by the trustee, we may cause such declaration of acceleration to be rescinded and annulled with respect to the debt securities of any series if we deposit with the trustee an amount sufficient to pay all overdue interest on the debt securities of that series, the

17

principal of and premium, if any, on the debt securities of that series that have become due and payable otherwise than by such declaration of acceleration and all amounts due to the trustee and if all other events of default with respect to the debt securities of that series have been cured or waived.

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

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

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

Defeasance

Unless the applicable prospectus supplement provides otherwise, any debt securities, or portion of the principal amount of the debt securities, will be deemed to have been paid for purposes of the applicable indentures, and, at our election, our entire indebtedness with respect to the debt securities, or portion thereof, will be deemed to have been satisfied and discharged, if we have irrevocably deposited with the trustee or any paying agent other than us, in trust, money, certain eligible obligations, as defined in the applicable indentures, or a combination of the two, sufficient to pay principal of and any premium and interest due and to become due on the debt securities or portions thereof.

The applicable prospectus supplement will describe, if applicable, our ability to be released from any of our covenant obligations under the indentures.

Modification and Waiver

The trustee under a particular indenture and Devon may, without the consent of holders, modify or waive provisions of that indenture for certain purposes, including, among other things, curing ambiguities and maintaining the qualification of the applicable indenture under the Trust Indenture Act of 1939, as amended. The trustee under a particular indenture and Devon may modify or waive certain provisions of that indenture with the consent of the holders of not less than a majority in aggregate principal amount of the debt securities of each series issued under that indenture affected by the modification or waiver. However, the provisions of any indenture may not be waived or modified without the consent of the holders of each debt security affected thereby if the modification or waiver would:

18

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

Consolidation, Merger and Sale of Assets

We may not consolidate with or merge into, or convey, transfer or lease our properties and assets substantially as an entirety to, any person (as defined in the applicable indenture) unless:

Covenants

Unless otherwise specified in the prospectus supplement, the following covenants will apply to the senior debt securities issued by Devon. Various capitalized terms used within this “Covenants” subsection are defined at the end of this subsection.

Liens

Neither Devon nor any of its Restricted Subsidiaries may incur, issue, assume or guarantee any Debt that is secured by a Mortgage on any Principal Property or on any shares of stock or Indebtedness of any Restricted Subsidiary of Devon, without first effectively providing that the debt securities (together with, if Devon so

19

determines, any other indebtedness of Devon or its Restricted Subsidiaries that is not subordinate in right of payment to the prior right of payment in full of the debt securities) will be secured equally and ratably with, or prior to, the incurred, issued, assumed or guaranteed secured Debt, for so long as this secured Debt remains so secured.

This limitation on the incurrence, issuance, assumption or guarantee of any Debt secured by a Mortgage will not apply to, and there will be excluded from any secured Debt in any computation under this covenant, Debt secured by:

provided that, if a commitment for the financing is obtained prior to or within this one-year period, the applicable Mortgage will be deemed to be included in this clause whether or not the Mortgage is created within this one-year period;

20

Notwithstanding anything mentioned above, Devon and any one or more of its Restricted Subsidiaries may incur, issue, assume or guarantee Debt secured by Mortgages that would otherwise be subject to the above restrictions if the aggregate amount of the Debt secured by the Mortgages, together with the outstanding principal amount of all other secured Debt of Devon and its Restricted Subsidiaries that would otherwise be subject to the above restrictions, does not exceed 15% of Consolidated Net Tangible Assets.

The following transactions shall not be deemed to create Debt secured by a Mortgage:

Definitions

“Consolidated Net Tangible Assets” means, calculated as of the date of the financial statements for the most recently ended fiscal quarter or fiscal year, as applicable, prior to the date of determination, the aggregate amount of assets of Devon and its consolidated subsidiaries, less applicable reserves and other properly deductible items but including investments in non-consolidated entities, after deducting therefrom:

“Debt” means indebtedness for money borrowed.

“Funded Debt” means all Debt of Devon or any of its subsidiaries for money borrowed, which is not by its terms subordinated in right of payment to the prior payment in full of the debt securities, having a maturity of more than 12 months from the date as of which the amount thereof is to be determined or having a maturity of fewer than 12 months but by its terms being:

“Indebtedness” means Debt.

21

“Mortgage” means and includes any mortgage, pledge, lien, security interest, conditional sale or other title retention agreement or other similar encumbrance.

“Offshore” means the lands beneath the navigable waters of the U.S. or Canada, or the continental shelf of the U.S. or Canada.

“Ordinary Course Mortgages” means:

“Principal Property” means any oil, gas or mineral producing property, or any refining, processing, smelting or manufacturing facility located in the U.S., Canada or Offshore, other than:

22

“Restricted Subsidiary” means Devon Financing Company, L.L.C. and any other subsidiary of Devon:

“Stockholders’ Equity” means, with respect to any corporation, partnership, joint venture, association, joint stock company, limited liability company, unlimited liability company, trust, unincorporated organization or government, or any agency or political subdivision thereof, stockholders’ equity, as computed in accordance with accounting principles generally accepted in the United States.

The Trustee

We may appoint a separate trustee for any series of debt securities. In the description of a series of debt securities, the term “trustee” refers to the trustee appointed with respect to such series of debt securities. The trustee may be a depository for funds and perform other services for, and may transact other banking business with, Devon and its subsidiaries in the normal course of business.

Subordination of Subordinated Debt Securities

Our obligations pursuant to any Devon subordinated debt securities will be unsecured and will be subordinate and junior in priority of payment to certain of our other indebtedness to the extent described in a prospectus supplement. The Devon subordinated indenture does not limit the amount of senior indebtedness we may incur. It also does not limit us from issuing any other secured or unsecured debt.

23

DESCRIPTION OF STOCK PURCHASE CONTRACTS AND STOCK PURCHASE UNITS

The following description of stock purchase contracts and stock purchase units sets forth certain general terms and provisions of the stock purchase contracts and stock purchase units to which this prospectus and any prospectus supplement may relate. The particular terms of any stock purchase contracts and stock purchase units and the extent to which the general provisions may apply to such stock purchase contracts and stock purchase units will be described in a prospectus supplement relating to such stock purchase contracts and stock purchase units.

We may issue stock purchase contracts, including contracts obligating holders to purchase from or sell to us, and obligating us to sell to or purchase from the holders, a specified number of shares of common stock or other securities at a future date or dates, which we refer to in this prospectus as “stock purchase contracts.” The price per share of the securities and the number of shares of the securities 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, and may be subject to adjustment under anti-dilution formulas. The stock purchase contracts may be issued separately or as part of units consisting of a stock purchase contract and debt securities, preferred securities or debt obligations of third parties, including U.S. treasury securities, any other securities described in the applicable prospectus supplement or any combination of the foregoing, securing the holders’ obligations to purchase the securities under the stock purchase contracts, which we refer to herein as “stock purchase units.” The stock purchase contracts may require holders to secure their obligations under the stock purchase contracts in a specified manner. The stock purchase contracts also may require us to make periodic payments to the holders of the stock purchase contracts or the stock purchase units, as the case may be, or vice versa, and those payments may be unsecured or pre-funded in whole or in part.

The applicable prospectus supplement will describe the terms of the stock purchase contracts or stock purchase units. This description is not complete and the description in the prospectus supplement will not necessarily be complete, and reference is made to the stock purchase contracts, and, if applicable, collateral or depositary arrangements relating to the stock purchase contracts or stock purchase units, which will be filed with the SEC each time we issue stock purchase contracts or stock purchase units. Material United States federal income tax considerations applicable to the stock purchase units and the stock purchase contracts will also be discussed in the applicable prospectus supplement.

24

BOOK-ENTRY SECURITIES

Unless otherwise specified in the applicable prospectus supplement, we will issue securities, other than our common stock, to investors in the form of one or more book-entry certificates registered in the name of a depository or a nominee of a depository. Unless otherwise specified in the applicable prospectus supplement, the depository will be DTC. We have been informed by DTC that its nominee will be Cede & Co. or Cede. Accordingly, Cede is expected to be the initial registered holder of all securities that are issued in book-entry form.

No person that acquires a beneficial interest in securities issued in book-entry form will be entitled to receive a certificate representing those securities, except as set forth in this prospectus or in the applicable prospectus supplement. Unless and until definitive securities are issued under the limited circumstances described below, all references to actions by holders or beneficial owners of securities issued in book-entry form will refer to actions taken by DTC upon instructions from its participants, and all references to payments and notices to holders or beneficial owners will refer to payments and notices to DTC or Cede, as the registered holder of such securities.

DTC has informed us that it is:

DTC has also informed us that it was created to:

Participants have accounts with DTC and include securities brokers and dealers, banks, trust companies and clearing corporations. Indirect access to the DTC system also is available to indirect participants such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a participant, either directly or indirectly.

Persons that are not participants or indirect participants but desire to buy, sell or otherwise transfer ownership of or interests in securities may do so only through participants and indirect participants. Under the book-entry system, beneficial owners may experience some delay in receiving payments, as payments will be forwarded by our agent to Cede, a nominee for DTC. These payments will be forwarded to DTC’s participants, which thereafter will forward them to indirect participants or beneficial owners. Beneficial owners will not be recognized by the applicable registrar, transfer agent, trustee or depositary as registered holders of the securities entitled to the benefits of the certificate, the indenture or any deposit agreement. Beneficial owners that are not participants will be permitted to exercise their rights as an owner only indirectly through participants and, if applicable, indirect participants.

Under the current rules and regulations affecting DTC, DTC will be required to make book-entry transfers of securities among participants and to receive and transmit payments to participants. Participants and indirect participants with whom beneficial owners of securities have accounts are also required by these rules to make book-entry transfers and receive and transmit such payments on behalf of their respective account holders.

25

Because DTC can act only on behalf of participants, who in turn act only on behalf of other participants or indirect participants, and on behalf of certain banks, trust companies and other persons approved by it, the ability of a beneficial owner of securities issued in book-entry form to pledge those securities to persons or entities that do not participate in the DTC system may be limited due to the unavailability of physical certificates for the securities.

DTC has advised us that it will take any action permitted to be taken by a registered holder of any securities under the certificate, the indenture or any deposit agreement only at the direction of one or more participants to whose accounts with DTC the securities are credited.

According to DTC, it has provided information with respect to DTC to its participants and other members of the financial community for informational purposes only and is not intended to serve as a representation, warranty or contract modification of any kind.

Unless otherwise specified in the applicable prospectus supplement, a book-entry security will be exchangeable for definitive securities registered in the names of persons other than DTC or its nominee only if:

Any book-entry security that is exchangeable in accordance with the preceding sentence will be exchangeable for securities registered in such names as DTC directs.

If one of the events described in the immediately preceding paragraph occurs, DTC is generally required to notify all participants of the availability through DTC of definitive securities. Upon surrender by DTC of the book-entry security representing the securities and delivery of instructions for re-registration, the registrar, transfer agent, trustee or depositary, as the case may be, will reissue the securities as definitive securities. After reissuance of the securities, such persons will recognize the beneficial owners of such definitive securities as registered holders of securities.

Except as described above:

None of Devon, the trustees, any registrar and transfer agent or any depository, or any agent of any of them, will have any responsibility or liability for any aspect of DTC’s or any participant’s records relating to, or for payments made on account of, beneficial interests in a book-entry security.

26

PLAN OF DISTRIBUTION

We may sell the securities being offered hereby in and outside the United States (1) through underwriters or dealers for resale to purchasers, (2) directly to purchasers, including our affiliates and stockholders, in a rights offering or otherwise, (3) through agents or (4) through a combination of any of these methods. The prospectus supplement will include the following information:

In addition, we may enter into derivative or hedging transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. In connection with such a transaction, the third parties may sell securities covered by and pursuant to this prospectus and any accompanying prospectus supplement. If so, the third party may use securities borrowed from us or others to settle such sales and may use securities received from us to close out any related short positions. We may also loan or pledge securities covered by this prospectus and any accompanying prospectus supplement to third parties, who may sell the loaned securities or, in an event of default in the case of a pledge, sell the pledged securities pursuant to this prospectus and any accompanying prospectus supplement.

Sale Through Underwriters or Dealers

If we use underwriters in the sale of securities, we will execute an underwriting agreement with the underwriters at the time of sale and we will provide the name of any underwriter in the prospectus supplement that the underwriters will use to make resales of securities to the public. The underwriters will acquire the securities for their own account, and 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. The obligations of the underwriters to purchase the securities will be subject to conditions unless we inform you otherwise in the prospectus supplement, and any underwritten offering may be on a best efforts or a firm commitment basis. 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, which means that selling concessions allowed to syndicate members or other broker-dealers for the offered securities sold for their account may be reclaimed by the syndicate if the 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, the underwriters may discontinue these activities at any time.

Some or all of the securities we offer through this prospectus may be new issues of securities with no established trading market. Any underwriters to whom we sell our securities for public offering and sale may make a market in those securities, but they will not be obliged to do so and they may discontinue any market making at any time without notice. Accordingly, we cannot assure you of the liquidity of, or continued trading markets for, any securities that we offer.

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

Direct Sales and Sales Through Agents

We may sell the securities directly. In this case, 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 offered securities, and we will describe any commissions payable by us to the agent. Unless we inform you otherwise in the prospectus supplement, any agent will agree to use its reasonable best efforts to solicit purchases for the period of its appointment.

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

We may also make direct sales through subscription rights distributed to our existing stockholders on a pro rata basis, which may or may not be transferable. In any distribution of subscription rights to our stockholders, if all of the underlying securities are not subscribed for, we may then sell the unsubscribed securities directly to third parties or may engage the services of one or more underwriters, dealers or agents, including standby underwriters, to sell the unsubscribed securities to third parties.

Delayed Delivery or Forward 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 set forth in the prospectus under delayed delivery or forward contracts. These contracts would provide for payment and delivery on a specified date in the future at prices determined as described in the prospectus supplement. The prospectus supplement would describe the commission payable for solicitation of those contracts.

Remarketing

We may offer and sell any of the securities, if so indicated in the applicable prospectus supplement, in connection with a remarketing upon their purchase, in accordance with a redemption or repayment by their terms or otherwise by one or more remarketing firms acting as principals for their own accounts or as our agents. We will identify any remarketing firm, the terms of any remarketing agreement, if any, with us and the compensation to be paid to the remarketing firm in the prospectus supplement. Remarketing firms may be deemed underwriters under the Securities Act, in connection with the securities remarketed.

Derivative Transactions

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

28

applicable prospectus supplement, including in short sale transactions. If so, the third parties may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of stock, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of stock. The third parties in these sale transactions will be underwriters and, if not identified in this prospectus, will be identified in the applicable prospectus supplement or in a post-effective amendment to the registration statement of which this prospectus forms a part. In addition, we may otherwise loan or pledge securities to a financial institution or other third party that in turn may sell the securities short using this prospectus. Such financial institution or other third party may transfer its economic short position to investors in our securities or in connection with a concurrent offering of other securities.

General Information

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

WHERE YOU CAN FIND MORE INFORMATION

We file annual, quarterly and other reports, proxy statements and other information with the SEC. The SEC maintains an Internet site (http://www.sec.gov) that contains reports, proxy statements, and other information we file electronically with the SEC.

As allowed by SEC rules, this prospectus does not contain all the information you can find in the registration statement or the exhibits to the registration statement. Instead, the SEC allows us to “incorporate by reference” information into this prospectus, which means that we can disclose important information to you by referring you to another document filed separately with the SEC. The information incorporated by reference is an important part of this prospectus, and information we file later with the SEC will automatically update and supersede this information. The information incorporated by reference is deemed to be part of this prospectus, except for any information superseded by information in, or incorporated by reference in, this prospectus.
