All statements, other than statements of historical fact included or incorporated by reference in this prospectus, regarding our strategy, future operations, financial position, estimated revenues and losses, projected costs, prospects, plans and objectives of management are forward-looking statements. Words such as “may,” “assume,” “forecast,” “position,” “predict,” “strategy,” “expect,” “intend,” “plan,” “estimate,” “anticipate,” “believe,” “project,” “budget,” “potential,” or “continue,” and similar expressions are used to identify forward-looking statements, although not all forward-looking statements contain such identifying words. When considering these forward-looking statements, you should keep in mind the risk factors and other cautionary statements described or referenced under the heading “Risk Factors” in this prospectus and under “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2024 and our subsequent Quarterly Reports on Form 10-Q. Each forward-looking statement is based on management’s current beliefs, based on currently available information, as to the outcome and timing of future events at the time such statement was made. Factors that could cause our actual results to differ materially from the results contemplated by such forward-looking statements include:

•

our ability to obtain debt or equity financing on satisfactory terms to fund acquisitions, expansion projects, capital expenditures, working capital requirements and the repayment or refinancing of indebtedness;

•

our ability to execute our return of capital program;

•

timing and amount of future production of natural gas, NGLs and oil;

our ability to achieve our greenhouse gas reduction targets and the costs associated therewith;

•

general economic conditions;

•

credit markets; and

•

our other plans, objectives, expectations and intentions contained or incorporated by reference in this prospectus that are not historical.

We caution you that these forward-looking statements are subject to all of the risks and uncertainties incidental to our business, most of which are difficult to predict and many of which are beyond our control. These risks include, but are not limited to, commodity price volatility, inflation, supply chain or other disruption, availability and cost of drilling, completion and production equipment and services, environmental risks, drilling and completion and other operating risks, marketing and transportation risks, regulatory changes or changes in law, the uncertainty inherent in estimating natural gas, NGLs and oil reserves and in projecting future rates of production, cash flows and access to capital, the timing of development expenditures, conflicts of interest among our stockholders, impacts of geopolitical and world health events, cybersecurity risks, the state of markets for, and availability of, verified quality carbon offsets and the other risks described or referenced under the heading “Risk Factors” in this prospectus and in our Annual Report on Form 10-K for the year ended December 31, 2024 and in our subsequent Quarterly Reports on Form 10-Q, each of which is incorporated by reference herein.

Reserve engineering is a process of estimating underground accumulations of natural gas, NGLs and oil that cannot be measured in an exact manner. The accuracy of any reserve estimate depends on the quality of available data, the interpretation of such data, and the price and cost assumptions made by reservoir engineers. In addition, the results of drilling, testing and production activities, or changes in commodity prices, may justify revisions of estimates that were made previously. If significant, such revisions would change the schedule of any further production and development drilling. Accordingly, reserve estimates may differ significantly from the quantities of natural gas, NGLs and oil that are ultimately recovered.

Should one or more of the risks or uncertainties described in this prospectus or the documents incorporated by reference herein occur, or should underlying assumptions prove incorrect, our actual results and plans could differ materially from those expressed in any forward-looking statements.

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

Except as otherwise required by applicable law, we disclaim any duty to update any forward-looking statements to reflect events or circumstances after the date of this prospectus.

TABLE OF CONTENTS

ABOUT ANTERO RESOURCES CORPORATION

We are an independent oil and natural gas company engaged in the development, production, exploration and acquisition of natural gas, NGLs, and oil properties located in the Appalachian Basin. We focus on unconventional reservoirs, which can generally be characterized as fractured shale formations. Our management team has worked together for many years and has a successful track record of reserve and production growth as well as significant expertise in unconventional resource plays. Our strategy is to leverage our team’s experience delineating and developing natural gas resource plays to profitably grow our reserves and production, primarily on our existing multi-year inventory of drilling locations.

We have assembled a portfolio of long-lived properties that are characterized by what we believe to be high repeatability and low geologic risk. We have three reportable segments: (i) the exploration, development and production of natural gas, NGLs and oil; (ii) marketing of excess firm transportation capacity; and (iii) midstream services through our equity method investment in Antero Midstream. Our drilling opportunities are focused in the Appalachian Basin. All of our operations are conducted in the United States.

Our principal executive offices are located at 1615 Wynkoop Street, Denver, Colorado 80202, and our telephone number is (303) 357-7310. Our website address is www.anteroresources.com.

RISK FACTORS

An investment in our securities involves a significant degree of risk. Before you invest in our securities, you should carefully consider those risk factors included in our most recently filed Annual Report on Form 10-K, any of our subsequently filed Quarterly Reports on Form 10-Q and any of our subsequently filed Current Reports on Form 8-K, each of which is incorporated herein by reference, and those risk factors that may be included in any applicable prospectus supplement, together with all of the other information included in this prospectus, any prospectus supplement and the documents we incorporate by reference, in evaluating an investment in our securities. If any of these risks were actually to occur, our business, financial condition or results of operations could be materially adversely affected. Additional risks not presently known to us or that we currently believe are immaterial may also significantly impair our business operations and financial condition. Please read “Cautionary Statement Regarding Forward-Looking Statements.”

TABLE OF CONTENTS

USE OF PROCEEDS

Unless we specify otherwise in any prospectus supplement, we expect to use the net proceeds we receive from the sale of the securities covered by this prospectus for general corporate purposes, which may include, among other things:

•

repayment of indebtedness; and

•

funding working capital, capital expenditures and acquisitions.

The actual application of the net proceeds from the sale of any particular offering of securities using this prospectus will be described in the applicable prospectus supplement relating to such offering. The precise amount and timing of the application of these proceeds will depend upon our funding requirements and the availability and cost of other funds.

TABLE OF CONTENTS

DESCRIPTION OF CAPITAL STOCK

As of January 9, 2026, our authorized capital stock consisted of 1,000,000,000 shares of common stock, par value $0.01 per share, of which 308,510,105 shares were issued and outstanding, and 50,000,000 shares of preferred stock, par value $0.01 per share, of which none were issued and outstanding.

The following summary of our capital stock, the Certificate of Incorporation and Bylaws does not purport to be complete and is qualified in its entirety by reference to the provisions of applicable law and to the Certificate of Incorporation and Bylaws, which are both filed as exhibits to the registration statement of which this prospectus is a part.

Common Stock

Except as provided by law or in a preferred stock designation, holders of common stock are entitled to one vote for each share held of record on all matters submitted to a vote of the stockholders, have the exclusive right to vote for the election of directors and do not have cumulative voting rights. Except as otherwise required by law, holders of common stock are not entitled to vote on any amendment to the Certificate of Incorporation (including any certificate of designations relating to any series of preferred stock) that relates solely to the terms of any outstanding series of preferred stock if the holders of such affected series are entitled, either separately or together with the holders of one or more other such series, to vote thereon pursuant to the Certificate of Incorporation (including any certificate of designations relating to any series of preferred stock) or pursuant to the DGCL. Subject to prior rights and preferences that may be applicable to any outstanding shares or series of preferred stock, holders of common stock are entitled to receive ratably in proportion to the shares of common stock held by them such dividends and distributions (payable in cash, stock or otherwise), if any, as may be declared from time to time by our board of directors out of funds legally available therefor. All outstanding shares of common stock are fully paid and non-assessable and the shares of common stock that will be issued under this prospectus will be fully paid and non-assessable.

The holders of common stock have no preferences or rights of conversion, exchange, pre-emption or other subscription rights. There are no redemption or sinking fund provisions applicable to the common stock. In the event of any voluntary or involuntary liquidation, dissolution or winding-up of our affairs, holders of common stock are entitled to share ratably in our assets in proportion to the shares of common stock held by them that are remaining after payment or provision for payment of all of our debts and obligations and after distribution in full of preferential amounts to be distributed to holders of outstanding shares of preferred stock, if any.

Preferred Stock

The Certificate of Incorporation authorizes our board of directors, subject to any limitations prescribed by law, without further stockholder approval, to establish and to issue from time to time one or more series of preferred stock, par value $0.01 per share, covering up to an aggregate of 50,000,000 shares of preferred stock. Each series of preferred stock will cover the number of shares and will have the powers, preferences, rights, qualifications, limitations and restrictions determined by our board of directors, which may include, among others, dividend rights, liquidation preferences, voting rights, conversion rights, preemptive rights and redemption rights. Except as provided by law or in a preferred stock designation, the holders of preferred stock will not be entitled to vote at or receive notice of any meeting of stockholders.

Should we offer shares of preferred stock under this prospectus, a prospectus supplement relating to the particular series of preferred stock offered will include the specific terms of those shares of preferred stock, including, among other things, the following:

•

the designation, stated value and liquidation preference of the preferred stock and the number of shares of preferred stock offered;

•

the price at which the shares will be issued;

•

any conversion or exchange provisions of the shares of preferred stock;

•

any redemption or sinking fund provisions of the preferred stock;

•

any dividend rights of the preferred stock;

TABLE OF CONTENTS

•

a discussion of material U.S. federal income tax considerations; and

•

any additional rights, preferences, privileges, limitations and restrictions of the preferred stock.

Anti-Takeover Provisions of Our Certificate of Incorporation and Bylaws

Certain provisions of Delaware law, our Certificate of Incorporation and our Bylaws could make the following transactions more difficult: acquisitions of us by means of a tender offer, a proxy contest or otherwise; or removal of our incumbent officers and directors. These provisions may also have the effect of preventing changes in our management. It is possible that these provisions could make it more difficult to accomplish or could deter transactions that stockholders may otherwise consider to be in their best interest or in our best interests, including transactions that might result in a premium over the market price for our shares.

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

Delaware Law

Section 203 of the DGCL prohibits a Delaware corporation, including those whose securities are listed for trading on the NYSE, from engaging in any business combination with any interested stockholder for a period of three years following the date that the stockholder became an interested stockholder, unless:

•

the transaction is approved by the board of directors before the date the interested stockholder attained that status;

•

upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced; or

•

on or after such time the business combination is approved by the board of directors and authorized at a meeting of stockholders by at least two thirds of the outstanding voting stock that is not owned by the interested stockholder.

We have elected to not be subject to the provisions of Section 203 of the DGCL.

Amended and Restated Certificate of Incorporation and Third Amended and Restated Bylaws

Among other things, our Certificate of Incorporation and Bylaws:

•

establish advance notice procedures with regard to stockholder proposals relating to the nomination of candidates for election as directors or new business to be brought before meetings of our stockholders. These procedures provide that notice of stockholder proposals must be timely given in writing to our corporate secretary prior to the meeting at which the action is to be taken. Generally, to be timely, notice must be received at our principal executive offices not less than 90 days nor more than 120 days prior to the first anniversary date of the annual meeting for the preceding year (unless the date of the annual meeting is more than 30 days before or more than 60 days after such anniversary date, in which case such notice must be delivered no earlier than the close of business on the 120th day prior to such annual meeting or later than the close of business on the later of the 90th day prior to such annual meeting or, if the first public announcement of the date of such annual meeting is less than 100 days prior to the date of such annual meeting, the 10th day after the first public disclosure of the date of such meeting by us). Our Bylaws specify the requirements as to form and content of all stockholders’ notices. These requirements may preclude stockholders from bringing matters before the stockholders at an annual or special meeting;

•

provide our board of directors the ability to authorize undesignated preferred stock. This ability makes it possible for our board of directors to issue, without stockholder approval, preferred stock

TABLE OF CONTENTS

with voting or other rights or preferences that could impede the success of any attempt to change control of us. These and other provisions may have the effect of deferring hostile takeovers or delaying changes in control or management of our company;

•

provide that the authorized number of directors may be changed only by resolution of the board of directors;

•

provide that all vacancies, including newly created directorships, may, except as otherwise required by law or, if applicable, the rights of holders of a series of preferred stock, be filled by the affirmative vote of a majority of directors then in office, even if less than a quorum;

•

provide that any action required or permitted to be taken by the stockholders must be effected at a duly called annual or special meeting of stockholders and may not be effected by any consent in writing in lieu of a meeting of such stockholders, subject to the rights of the holders of any series of preferred stock with respect to such series;

•

provide our Certificate of Incorporation and Bylaws may be amended by the affirmative vote of the holders of at least two thirds of our then outstanding common stock;

•

provide that special meetings of our stockholders may only be called by our board of directors, the chief executive officer or the chairman of our board of directors;

•

provide for our board of directors to be divided into three classes of directors, with each class as nearly equal in number as possible, serving staggered three year terms, other than directors which may be elected by holders of preferred stock, if any. This system of electing and removing directors may tend to discourage a third party from making a tender offer or otherwise attempting to obtain control of us, because it generally makes it more difficult for stockholders to replace a majority of the directors;

•

provide that we renounce any interest in existing and future investments in other entities by, or the business opportunities of, our private equity sponsors or any of their respective officers, directors, agents, stockholders, members, partners, affiliates and subsidiaries (other than our directors that are presented business opportunities in their capacity as our directors) and that they have no obligation to offer us those investments or opportunities; and

•

provide that our Bylaws can be amended or repealed at any regular or special meeting of stockholders or by the board of directors, including the requirement that any amendment by the stockholders at a meeting be upon the affirmative vote of at least 662∕3% of the shares of common stock generally entitled to vote in the election of directors.

The debt securities will rank equally with all of our unsecured and unsubordinated debt. The Indenture is subject to the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”). The Indenture does not limit the amount of debt securities which we may issue, nor does it limit us or our subsidiaries from issuing any other unsecured debt. Such other unsecured debt may have different terms than the debt securities. Our previously issued and outstanding senior debt have different terms from the debt securities (including different restrictive covenants and event of default provisions). The terms of the debt securities issued under this prospectus will only be as described in the Indenture, this prospectus, any prospectus supplement and, if applicable, a pricing supplement.

Each prospectus supplement, together with a pricing supplement, if applicable, will describe the terms relating to a series of debt securities, which may include:

•

the title;

•

any limit on the amount that may be issued (unless expressly provided in the applicable prospectus supplement or pricing supplement, a series of our debt securities may be re-opened from time to time for the issuance of additional debt securities of that series, subject to the terms and conditions set forth in or established pursuant to the Indenture);

•

the price at which that series of debt securities will be issued, which may be at a discount or a premium;

the interest rate(s), if any (which may be fixed or variable), or the method for determining the rate(s) and the date(s) interest will begin to accrue, the date(s) interest will be payable and the regular record date(s) for interest payment date(s);

•

the place(s) where payments shall be payable, debt securities may be surrendered for registration of transfer, securities may be surrendered for exchange, and notices and demands to or upon us may be served;

•

the period(s) within which, and the price(s) at which, that series of debt securities may, pursuant to any optional or mandatory redemption provisions, be redeemed, in whole or in part, and other related terms and conditions;

•

any mandatory or optional sinking fund provisions or any provisions for remarketing that series of debt securities and other related terms and provisions;

•

the denominations in which that series of debt securities will be issued, if other than minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof;

•

the currency or currencies, including composite currencies or currency units, in which that series of debt securities may be denominated or in which payment of the principal of and interest, if any, on that

TABLE OF CONTENTS

series of debt securities shall be payable, if other than the currency of the United States of America, and, if so, whether that series of debt securities may be satisfied and discharged other than as provided in the Indenture;

•

if the amounts of payments of principal of and any interest on, that series of debt securities are to be determined by reference to an index, formula or other method, or based on a coin or currency other than that in which that series of debt securities are stated to be payable, the manner in which such amounts shall be determined and the calculation agent, if any, with respect thereto;

•

if that series of debt securities may be issued or delivered (whether upon original issuance or upon exchange of a temporary security of such series or otherwise), or any installment of principal or interest is payable, only upon receipt of certain certificates or other documents or satisfaction of other conditions in addition to those specified in the Indenture, the forms and terms of those certificates, documents or conditions;

•

whether the debt securities of such series are subject to subordination and the terms of such subordination;

•

any addition to, or modification or deletion of, any event of default, covenant or other term or provision specified in the Indenture with respect to that series of debt securities; and

•

any other terms, which other terms may (subject, in the case of an existing outstanding series of debt securities, to the provisions of the Indenture described below under “— Modification of Indenture; Waiver”) amend, supplement or replace any of the terms of the Indenture insofar as it concerns the debt securities of that series.

Each prospectus supplement or pricing supplement, as applicable, may describe material U.S. federal income tax considerations applicable to the purchase, holding and disposition of the debt securities that the prospectus supplement or pricing supplement covers, as applicable.

Consolidation, Merger or Sale

The Indenture does not permit us to consolidate with, merge into or convey, transfer or lease our properties and assets substantially as an entirety to any Business Entity unless the following conditions are met:

•

the Business Entity formed by such consolidation or into which we are merged or the Business Entity that acquires by conveyance or transfer, or which leases, our properties and assets substantially as an entirety shall be a Business Entity organized and existing under the laws of the United States of America, any state thereof or the District of Columbia and shall expressly assume, by a supplemental indenture, all of our obligations under the Indenture and the debt securities; and

•

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

If the conditions described above are satisfied with respect to the debt securities, we will not need to obtain the approval of the holders in order to engage in such a consolidation, merger, conveyance, transfer or lease. Also, these conditions will apply only if we wish to consolidate with or merge into, or convey, transfer or lease our properties and assets substantially as an entirety to, another entity. We will not need to satisfy these conditions if we enter into other types of transactions, including any transaction in which we acquire the stock or assets of another entity and any transaction that involves a change of control of Antero but in which we do not consolidate with or merge into another entity, as well as any transaction in which we convey, transfer or lease our properties and assets other than substantially as an entirety to a Business Entity.

Reports

The Indenture provides that we will file with the Trustee, within 15 days after we have filed the same with the United States Securities and Exchange Commission (the “Commission”), copies of the annual reports and of the information, documents and other reports (or copies of such portions of any of the foregoing as the Commission may from time to time by rules and regulations prescribe) which we may be required to file with the Commission pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934; provided that we will be deemed to have filed copies of any such annual reports, documents or other reports with the Trustee to the extent that such annual reports, documents or other reports are filed with the Commission via EDGAR (or any successor electronic delivery procedure).

TABLE OF CONTENTS

Delivery of reports, information and documents to the Trustee are for informational purposes only and the Trustee’s receipt of the foregoing shall not constitute constructive or actual knowledge or notice of any information contained therein or determinable from information contained therein, including our compliance with any of our covenants under the Indenture (as to which the Trustee is entitled to rely exclusively on officer’s certificates). The Trustee shall not be obligated to monitor or confirm, on a continuing basis or otherwise, our compliance with the covenants described herein, to determine whether such reports, information or other documents have been filed with the Commission (whether via EDGAR or any successor electronic delivery procedure) or posted on any website or datasite under the Indenture, to examine such reports, information or documents to ensure compliance with the provisions of the Indenture or to ascertain the correctness or otherwise of the information or the statements contained therein or to participate in any conference calls.

Events of Default and Remedies Under the Indenture

The following are events of default under the Indenture with respect to each series of debt securities:

•

failure to pay any installment of interest upon any debt securities of such series when it becomes due and payable, and continuance of such failure to pay for a period of 30 days;

•

failure to pay the principal of any debt securities of such series when due;

•

failure to perform or breach of any other covenant or warranty contained in the debt securities or the Indenture (other than a covenant or warranty specifically benefiting only another series of debt securities), and the continuance of such failure or breach for a period of 90 days after we receive notice of such failure or breach from the Trustee or holders of at least 25% in principal amount of the outstanding debt securities of that series;

•

certain events of bankruptcy, insolvency or reorganization relating to us; and

•

any other event of default specified in the prospectus supplement or pricing supplement, if any, relating to that series of debt securities.

If an event of default with respect to the debt securities of any series occurs and is continuing, the Trustee or the holders of at least 25% in principal amount of the outstanding debt securities of that series, by notice in writing to us (and to the Trustee if notice is given by such holders), may declare the principal of (or if such debt securities are Original Issue Discount Securities, the portion of the principal amount specified in the applicable prospectus supplement or pricing supplement, if any), and accrued interest, if any, on the debt securities of such series to be due and payable immediately. At any time after such a declaration of acceleration has been made and before a judgment or decree for payment of the money due has been obtained, holders of a majority in principal amount of the outstanding debt securities of that series, by written notice to us and the Trustee, may rescind and annul such declaration and its consequences if:

•

we have paid or deposited with the Trustee a sum sufficient to pay all overdue installments of interest on the debt securities of that series, the principal of any debt securities of that series which has become due otherwise than by such declaration of acceleration and interest thereon, to the extent payment of such interest is lawful, interest on overdue installments of interest, all sums paid or advanced by the Trustee, the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and any other amount due to the Trustee under the Indenture, and

•

all events of default with respect to outstanding debt securities of that series, other than the non-payment of the principal of and interest on such debt securities which became due solely by such declaration of acceleration, have been cured or waived in accordance with the terms of the Indenture.

The holders of a majority in principal amount of the outstanding debt securities of any series may waive any past default with respect to that series and its consequences, except defaults regarding:

•

payment of principal or interest; or

•

covenants that cannot be modified or amended without the consent of each holder of an outstanding debt security affected thereby (as described under “— Modification of Indenture; Waiver” below).

Any waiver shall cure such default and the corresponding event of default.

TABLE OF CONTENTS

Subject to the terms of the Indenture, the Trustee will be 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 the applicable series of debt securities, unless the holders have offered the Trustee security or indemnity satisfactory to the Trustee against costs, expenses and liabilities to be incurred in compliance with such request. The holders of a majority in principal amount of the outstanding debt securities of any series will have the right to 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; provided that:

•

the direction given to the Trustee is not in conflict with any law or the Indenture;

•

the Trustee may take any other action deemed proper by it which is not inconsistent with that direction; and

•

the Trustee has not determined that the action would be unjustly prejudicial to the holders not involved in the proceeding (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not such action would be unjustly prejudicial to such holders).

A holder of the debt securities of any series will have the right to institute a proceeding under the Indenture or to appoint a receiver or trustee, or to seek other remedies only if:

•

the holder has given written notice to Trustee of a continuing event of default with respect to that series;

•

the holders of at least 25% in principal amount of the outstanding debt securities of that series have made written request, and have offered indemnity satisfactory to the Trustee to institute the proceedings as trustee; and

•

the Trustee does not institute the proceeding, and does not receive from the holders of a majority in principal amount of the outstanding debt securities of that series other conflicting directions, within 60 days after the notice, request and offer of indemnity.

The Indenture provides that no holder or group of holders of debt securities will have any right to affect, disturb or prejudice the rights of other holders, obtain or seek priority or preference over another holder or enforce its rights under the Indenture except as provided in the Indenture for the equal and ratable benefit of all holders (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not such actions affect, disturb or prejudice the rights of such Holders or obtain or seek to obtain priority or preference over such Holders).

These limitations on instituting proceedings do not apply to a suit instituted by a holder of debt securities to enforce the payment of the principal of or interest on the debt securities.

We will periodically deliver statements to the Trustee regarding the existence or absence of defaults under the Indenture.

Modification of Indenture; Waiver

•

evidence the succession of another Business Entity to us and the assumption by such successor of our covenants, agreements and obligations in the Indenture and the debt securities;

•

add to or change or eliminate any provision of the Indenture as shall be necessary to comply with any amendments to the Trust Indenture Act or to otherwise maintain qualification of the Indenture under the Trust Indenture Act or to comply with the rules of any applicable depositary;

•

modify any of the foregoing requirements or the provisions regarding waivers of any covenant or past default other than to increase the percentage of holders required for consent or waiver or add consent requirements for modification or waiver of other provisions.

The Trustee, other than during the occurrence and continuance of an event of default under the Indenture, undertakes to perform only those duties as are specifically set forth in the Indenture and, upon an event of default under the Indenture, must use the same degree of care as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs. Subject to this provision, the Trustee is under no obligation to exercise any of the rights or powers given it by the Indenture at the request or direction of any holder of debt securities unless the Trustee is offered security or indemnity by that holder against the costs, expenses and liabilities that it might incur. The Trustee is not required to spend or risk its own money or otherwise become financially liable while performing its duties unless it believes that it will be repaid or receive adequate indemnity to the Trustee’s satisfaction.

Payment and Payment Agents

The person in whose name a debt security is registered will be treated as the owner of such security for the purpose of receiving payment of principal and, unless otherwise indicated in an applicable prospectus supplement or pricing supplement, if any, interest on such debt security and for all other purposes.

Unless otherwise indicated in the applicable prospectus supplement or pricing supplement, if any, payment of interest on any debt securities on any interest payment date will be made to the person in whose name those debt securities (or one or more predecessor securities) are registered at the close of business on the regular record date for the interest, except as otherwise provided by the procedures of the depositary. Unless otherwise indicated in the applicable prospectus supplement or pricing supplement, if any, principal and interest on the debt securities of a particular series will be payable at the office of the paying agents that we designate, except that payments of interest may, at our option, be made by wire transfer or check mailed to the address of the person entitled thereto.

We will be required to maintain a paying agent in each place of payment for the debt securities of a particular series. Unless otherwise indicated in the applicable prospectus supplement or pricing supplement, if any, the corporate trust office or agency of the Trustee in the United States will be designated as the paying agent for payments with respect to debt securities.

Subject to applicable abandoned property law, all moneys that we pay to a paying agent or the Trustee for the payment of the principal or interest, if any, on any debt securities which remain unclaimed at the end of two years after that principal or interest has become due and payable will be repaid to us, and the holder of the security thereafter may look only to us for payment thereof.

Unless otherwise indicated in an applicable prospectus supplement or pricing supplement, if any, interest shall be computed, for fixed rate securities, on the basis of a 360-day year comprised of twelve 30-day months, and, for variable rate securities, on the basis of the actual number of days in the interest period divided by 360.

We may engage in at-the-market offerings and offer our securities into an existing trading market in accordance with Rule 415(a)(4) under the Securities Act on the terms described in the prospectus supplement relating thereto. Underwriters, dealers, and agents who participate in any at-the-market offerings will be described in the prospectus supplement relating thereto.

We may agree to indemnify underwriters, dealers, and agents who participate in the distribution of securities against certain liabilities to which they may become subject in connection with the sale of the securities, including liabilities arising under the Securities Act.

Certain of the underwriters and their affiliates may be customers of, may engage in transactions with and may perform services for us or our affiliates in the ordinary course of business.

A prospectus and accompanying prospectus supplement in electronic form may be made available on the websites maintained by the underwriters. The underwriters may agree to allocate a number of securities for sale to their online brokerage account holders. Such allocations of securities for internet distributions will be made on the same basis as other allocations. In addition, securities may be sold by the underwriters to securities dealers who resell securities to online brokerage account holders.

TABLE OF CONTENTS

To the extent required, this prospectus may be amended or supplemented from time to time to describe a specific plan of distribution. The place and time of delivery for the securities in respect of which this prospectus is delivered will be set forth in the accompanying prospectus supplement.

In connection with offerings of securities under the registration statement of which this prospectus forms a part and in compliance with applicable law, underwriters, brokers, or dealers may engage in transactions that stabilize or maintain the market price of the securities at levels above those that might otherwise prevail in the open market. Specifically, underwriters, brokers, or dealers may over-allot in connection with offerings, creating a short position in the securities for their own accounts. For the purpose of covering a syndicate short position or stabilizing the price of the securities, the underwriters, brokers, or dealers may place bids for the securities or effect purchases of the securities in the open market. Finally, the underwriters may impose a penalty whereby selling concessions allowed to syndicate members or other brokers or dealers for distribution of the securities in offerings may be reclaimed by the syndicate if the syndicate repurchases previously distributed securities in transactions to cover short positions, in stabilization transactions or otherwise. These activities may stabilize, maintain, or otherwise affect the market price of the securities, which may be higher than the price that might otherwise prevail in the open market, and, if commenced, may be discontinued at any time.

TABLE OF CONTENTS

LEGAL MATTERS

The validity of the securities offered by this prospectus will be passed upon for us by Vinson & Elkins L.L.P., Houston, Texas. If certain legal matters in connection with an offering of the securities made by this prospectus and a related prospectus supplement are passed upon by counsel for the underwriters of such offering, that counsel will be named in the applicable prospectus supplement related to that offering.

ITEM 14. Other Expenses of Issuance and Distribution

Set forth below are the expenses (other than underwriting discounts and commissions) expected to be incurred in connection with the offering of the securities registered hereby.

SEC registration fee	$	*
Printing and engraving expenses		**
Accounting fees and expenses		**
Legal fees and expenses		**
Transfer agent and registrar fees		**
Trustee fees and expenses		**
Miscellaneous		**
Total	$	**

The registrant is deferring payment of the registration fee in reliance on Rule 456(b) and 457(r) under the Securities Act.

These fees are calculated based on the number of issuances and amount of securities offered and accordingly cannot be estimated at this time.

ITEM 15. Indemnification of Directors and Officers

The DGCL authorizes corporations to limit or eliminate the personal liability of directors and officers to corporations and their stockholders for monetary damages for breaches of fiduciary duties. The DGCL does not permit exculpation for liability:

•

for breach of duty of loyalty;

•

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

•

under Section 174 of the DGCL (which deals generally with unlawful payments of dividends, stock repurchases and redemptions); and

•

for transactions from which the director derived improper personal benefit.

The Certificate of Incorporation eliminates the personal liability of directors and officers for monetary damages for any breach of fiduciary duty, except to the extent such exemption is not permitted under the DGCL.

The Bylaws provide that we shall, to the fullest extent permitted by law, indemnify any person who was or is made or is threatened to be made a party or is otherwise involved in any action, suit or proceeding by reason of the fact such person is or was our director, officer or employee, or, while our director, officer or employee, is or was serving at our request as a director, officer, employee or agent of another entity, against all liability and loss suffered and expenses reasonably incurred. The Bylaws further provide that we shall advance expenses incurred in defending any such proceeding to any such indemnitees; provided, however, that, to the extent required by law, such advancement of expenses shall be made only upon receipt of an undertaking, by or on behalf of such indemnitee, to repay all amounts so advanced if it shall ultimately be determined that such indemnitee is not entitled to be indemnified for such expenses under our bylaws or otherwise.

II-1

TABLE OF CONTENTS

Any amendment to, or repeal of, these provisions will not eliminate or reduce the effect of these provisions in respect of any act, omission or claim that occurred or arose prior to that amendment or repeal. If the DGCL is amended to provide for further limitations on the personal liability of directors or officers of corporations, then the personal liability of our directors and officers will be further limited to the fullest extent permitted by the DGCL.

In addition, we entered into indemnification agreements with our current directors and officers containing provisions that are in some respects broader than the specific indemnification provisions contained in the DGCL. The indemnification agreements require us, among other things, to indemnify our directors against certain liabilities that may arise by reason of their status or service as directors and to advance their expenses incurred as a result of any proceeding against them as to which they could be indemnified. We also intend to enter into indemnification agreements with our future directors and officers.

We maintain liability insurance policies that indemnify our directors and officers against various liabilities, including certain liabilities under arising under the Securities Act and the Exchange Act, that may be incurred by them in their capacity as such.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling us pursuant to the foregoing provisions, we have been informed that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

ITEM 17. Undertakings

(a) The undersigned registrant hereby undertakes:

(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 of 1933;

(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 20 percent 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) do not apply if 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 Securities Exchange Act of 1934 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 of 1933, 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.

II-3

TABLE OF CONTENTS

(4) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

(i) Each prospectus filed by the 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) 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 of 1933 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 the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the 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, the 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 the 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 the undersigned registrant or used or referred to by the undersigned registrant;

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

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

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 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 of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the 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 the registrant of expenses incurred or paid by a director, officer or controlling person of the 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, the 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.
