**ABOUT THIS PROSPECTUS** 

This prospectus is part of an "automatic shelf" registration statement that we filed with the Securities and Exchange Commission (the "SEC") as a "well-known seasoned issuer" as defined in Rule 405 under the Securities Act of 1933, as amended (the "Securities Act"), using a "shelf" registration process. Under this process, we may sell common stock, preferred stock, depositary shares, warrants, purchase contracts and/or units consisting of any combination of such securities, either individually or in combination with other securities, in one or more offerings. Because we are a "well-known seasoned issuer," we may add to and offer additional securities, including secondary securities, by filing a prospectus supplement or term sheet with the SEC at the time of the offer.

This prospectus provides you with a general description of the common stock, preferred stock, depositary shares, warrants, purchase contracts or units that we may issue. Each time we sell securities, we will provide a prospectus supplement that will contain specific information about the terms of those securities and that offering. Such prospectus supplement may also add, update or change information contained in this prospectus. If there is any inconsistency between the information in this prospectus and any prospectus supplement, you should rely on the information in the prospectus supplement. You should carefully read this prospectus and the applicable prospectus supplement as well as additional information incorporated by reference herein and described under the heading "Where You Can Find More Information" before you invest in our securities. We may also prepare free writing prospectuses that describe particular securities. Any free writing prospectus should also be read in connection with this prospectus and with any prospectus supplement referred to therein. For purposes of this prospectus, any reference to an applicable prospectus supplement may also refer to a free writing prospectus, unless the context otherwise requires.

The registration statement that contains this prospectus, including the exhibits to the registration statement, contains additional information about us and the securities offered under this prospectus. That registration statement can be read at the SEC web site mentioned under the heading "Where You Can Find More Information."

When used in this prospectus, except where the context otherwise requires, references to the "Company," "we," "us" or "our" refer to Northern Oil and Gas, Inc., a Delaware corporation, and its consolidated subsidiaries.

**WHERE YOU CAN FIND MORE INFORMATION** 

We are subject to the information and periodic reporting requirements of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and, in accordance therewith, file periodic reports, proxy statements and other information with the SEC. Such periodic reports, proxy statements and other information are available at the website of the SEC at http://www.sec.gov.

**CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS** 

The information contained in, or incorporated by reference into, this prospectus includes "forward-looking statements" within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act. All statements other than statements of historical facts included in this prospectus, including the documents incorporated by reference herein, regarding our financial position, business strategy, plans and objectives of management for future operations, industry conditions, indebtedness covenant compliance, capital expenditures, production, cash flow, borrowing base under our revolving credit facility, our intention or ability to pay or increase dividends on our capital stock, and impairment are forward-looking statements. When used in this prospectus, forward-looking statements are generally accompanied by terms or phrases such as "estimate," "project," "predict," "believe," "expect," "continue," "anticipate," "target," "could," "plan," "intend," "seek," "goal," "will," "should," "may" or other words and similar expressions that convey the uncertainty of future events or outcomes. Items contemplating or making assumptions about actual or potential future production, sales, market size, collaborations, cash flows, and trends or operating results also constitute such forward-looking statements.

Forward-looking statements involve inherent risks and uncertainties, and important factors (many of which are beyond our control) that could cause actual results to differ materially from those set forth in the forward-looking statements, including the following: changes in crude oil and natural gas prices; the pace of drilling and completions activity on our current properties and properties pending acquisition; infrastructure constraints and related factors affecting our properties; general economic or industry conditions, whether internationally, nationally and/or in the communities in which the Company conducts business, including any future economic downturn, cost inflation, supply chain disruptions, the impact of continued or further inflation, disruption in the financial markets, changes in the interest rate environment and actions taken by OPEC and other oil producing countries as it pertains to the global supply and demand of, and prices for, crude oil, natural gas and NGLs; ongoing legal disputes over, and potential shutdown of, the Dakota Access Pipeline; our ability to identify and consummate additional development opportunities and potential or pending acquisition transactions, the projected capital efficiency savings and other operating efficiencies and synergies resulting from our acquisition transactions, integration and benefits of property acquisitions, or the effects of such acquisitions on our cash position and levels of indebtedness; changes in our reserves estimates or the value thereof; disruption to our business due to acquisitions and other significant transactions; changes in local, state, and federal laws, regulations or policies that may affect our business or our industry (such as the effects of tax law changes, and changes in environmental, health, and safety regulation and regulations addressing climate change, and trade policy and tariffs); conditions of the securities markets; risks associated with the Company's 3.625% convertible senior notes due 2029 (the "Convertible Notes"), including the potential impact that the Convertible Notes may have on the Company's financial position and liquidity, potential dilution, and that provisions of the Convertible Notes could delay or prevent a beneficial takeover of the Company; the potential impact of the capped call transactions undertaken in tandem with the Convertible Notes issuances, including counterparty risk; increasing attention to environmental, social and governance matters; our ability to raise or access capital on acceptable terms; cyber-incidents could have a material adverse effect on our business, financial condition or results of operations; changes in accounting principles, policies or guidelines; events beyond our control, including a global or domestic health crisis, acts of terrorism, political or economic instability or armed conflict in oil and gas producing regions and shipping channels, including the joint U.S.-Israel strikes on Iran, continued instability in the Middle East and the effects of any changes to conditions in or impacting Venezuela; and other economic, competitive, governmental, regulatory and technical factors affecting our operations, products and prices.

We have based any forward-looking statements on our current expectations and assumptions about future events. While our management considers these expectations and assumptions to be reasonable, they are inherently subject to significant business, economic, competitive, regulatory and other risks, contingencies and uncertainties, most of which are difficult to predict and many of which are beyond our control. Accordingly, results actually achieved may differ materially from expected results described in these statements. Forward-looking statements speak only as of the date they are made. You should consider carefully the statements under

v

##### [**Table of Contents**](#toc)
the heading "Risk Factors" herein, and in the section entitled "Item 1A. Risk Factors" and other sections of our Annual Report on Form 10-K for the fiscal year ended December 31, 2025, as updated by subsequent reports we file with the SEC, which describe factors that could cause our actual results to differ from those set forth in the forward-looking statements. The Company does not undertake, and specifically disclaims, any obligation to update any forward- looking statements to reflect events or circumstances occurring after the date of such statements, except as may be required by applicable law or regulation.

Readers are urged not to place undue reliance on these forward-looking statements, which speak only as of the date of this prospectus. Readers are urged to carefully review and consider the various disclosures made by the Company in our reports filed with the SEC which attempt to advise interested parties of the risks and factors that may affect our business, financial condition, results of operation and cash flows. If one or more of these risks or uncertainties materialize, or if the underlying assumptions prove incorrect, our actual results may vary materially from those expected or projected. All forward-looking statements, expressed or implied, included in this prospectus and the information incorporated herein are expressly qualified in their entirety by this cautionary statement.

**RISK FACTORS** 

An investment in our securities involves a high degree of risk. Before making an investment decision, you should carefully consider the risks, uncertainties and additional information (i) set forth in our most recent Annual Report on Form 10-K, any subsequent Quarterly Reports on Form 10-Q and Current Reports on Form 8-K, which are incorporated, or deemed to be incorporated, by reference into this prospectus, and in the other documents that we file with the SEC and are incorporated by reference in this prospectus and (ii) contained in or incorporated by reference into the applicable prospectus supplement and any applicable free writing prospectus. Our business, financial condition or results of operations could be materially and adversely affected by any of those risks. In such case, the trading price of our securities could decline and investors could lose all or part of their investment. See the section entitled "Where You Can Find More Information" in this prospectus.

**THE COMPANY** 

We are an independent energy company engaged as a non-operator in the acquisition, exploration, development and production of oil and natural gas properties in North America, primarily in the Permian Basin, the Williston Basin, the Appalachian Basin and the Uinta Basin in the United States, and in the Duvernay East Shale Basin in Alberta, Canada. We believe the location, size and concentration of our acreage positions in some of North America's leading unconventional oil and gas resource plays provide us with drilling and development opportunities that will result in significant long-term value.

Our primary strategy is to invest in non-operated minority working and mineral interests in oil and natural gas properties, with a core area of focus in the premier basins within North America. We seek to create value through strategic acquisitions and financially participating alongside operators who have significant experience in developing and producing hydrocarbons in our core areas.

Our principal executive offices are located at 4350 Baker Road **–** Suite 400, Minnetonka, Minnesota 55343, and our telephone number is 952-476-9800.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the terms and amounts of any sinking fund provided for the purchase or redemption of shares of the series;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the amounts payable on shares of the series in the event of any voluntary or involuntary liquidation, dissolution
or winding-up of the affairs of the Company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• whether the shares of the series will be convertible into shares of any other class or series, or any other
security, of the Company or any other corporation, and, if so, the specification of the other class or series or other security, the conversion price or prices or rate or rates, any rate adjustments, the date or dates as of which the shares will be
convertible and all other terms and conditions upon which the conversion may be made;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• restrictions on the issuance of shares of the same series or of any other class or series; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the voting rights, if any, of the holders of the series.

Accordingly, we could issue a series of preferred stock that could, depending on the terms of the series, impede or discourage an acquisition attempt or other transaction that some, or a majority, of common stockholders might believe to be in their best interests or in which common stockholders might receive a premium for their common stock over the market price of the common stock.

**Anti-Takeover Provisions** 

***Advance Notice Requirements for Director Nominations and Stockholder Proposals***

Our Bylaws provide that stockholders seeking to nominate candidates for election as directors or to bring business before an annual meeting of stockholders must provide timely notice of their proposal in writing to our corporate secretary. Any such stockholder must be a stockholder of record at the time such notice is delivered to the corporate secretary, at the time of the record date of the annual meeting and at the time of the annual meeting, and must appear, or be represented by proxy, at the applicable annual meeting.

------

##### [**Table of Contents**](#toc)
Generally, to be timely, a stockholder's notice must be received at our principal executive offices not less than 90 days, nor earlier than 120 days, prior to the first anniversary of the previous year's annual meeting; provided, however, that if the date of the annual meeting is advanced or delayed by more than 30 days before or 60 days after such anniversary date, such notice must be delivered to the corporate secretary not earlier than the close of business on the 120th day prior to such annual meeting and not later than the close of business on the later of the 90th day prior to such annual meeting or the tenth day following the day on which the public announcement of the date of such annual meeting is first made by us.

Our Bylaws also specify detailed requirements as to the form and content of a stockholder's notice (including disclosure with respect to such stockholder and the nominee or proposed business, as applicable) and, in the case of nominations of candidates for election as directors, require a completed D&O questionnaire and nominee agreement from each such nominee. Any stockholder seeking to nominate candidates for election as directors must further deliver to us certain certifications and representations, as well as reasonable evidence that such stockholder has complied with the requirements of Rule 14a-19 of the Exchange Act not later than eight business days prior to the annual meeting. Such proposed nominee may be required by us to deliver to us certain representations and agreements. We may also, as a condition to any such nomination or business being deemed properly brought before an annual meeting of stockholders, require such stockholder or any proposed nominee to deliver to the corporate secretary, within five business days of any such request, such other information as may reasonably be requested by us, including (i) such other information as may be reasonably required by our Board, in its sole discretion, to determine (A) the eligibility of such proposed nominee to serve as a director of the Company, and (B) whether such proposed nominee qualifies as an "independent director" or "audit committee financial expert" under applicable law, securities exchange rule or regulation, or any publicly disclosed corporate governance guideline or committee charter of the Company and (ii) such other information that our Board determines, in its sole discretion, could be material to a reasonable stockholder's understanding of the independence, or lack thereof, of such proposed nominee.

A stockholder's notice must be updated and supplemented, if necessary, so that the information provided or required to be provided in such notice is true and correct as of the record date for the annual meeting of stockholders and as of the date that is ten business days prior to the annual meeting of stockholders or any adjournment, recess, rescheduling or postponement thereof, and such update and supplement must be delivered to the corporate secretary not later than five business days after the record date for the annual meeting of stockholders in the case of the update and supplement required to be made as of the record date, and not later than eight business days prior to the date for the annual meeting of stockholders or any adjournment, recess, rescheduling or postponement thereof in the case of the update and supplement required to be made as of ten business days prior to the annual meeting of stockholders or any adjournment, recess, rescheduling or postponement thereof.

These provisions may impede stockholders' ability to bring matters before an annual meeting of stockholders or make nominations for directors at an annual meeting of stockholders and may delay, deter or prevent tender offers or takeover attempts that stockholders may believe are in their best interests, including tender offers or attempts that might allow stockholders to receive premiums over the market price of their common stock.

***Issuance of Preferred Stock***

Our Board can at any time, under our Certificate of Incorporation, and without stockholder approval, issue one or more new series of preferred stock. In some cases, the issuance of preferred stock without stockholder approval could discourage or make more difficult attempts to take control of the Company through a merger, tender offer, proxy contest or otherwise. Preferred stock with special voting rights or other features issued to persons favoring our management could stop a takeover by preventing the person trying to take control of the Company from acquiring enough voting shares necessary to take control.

------

##### [**Table of Contents**](#toc)
***Special Meetings of Stockholders***

Our Bylaws provide that a special meeting of stockholders may be called only by a majority of our Board.

***Anti-Takeover Provisions of the Delaware General Corporation Law***

As a Delaware corporation, we are subject to Section 203 of the DGCL. This provision provides that a corporation that is listed on a national securities exchange or that has more than 2,000 stockholders is not permitted to engage in a business combination with any interested stockholder, generally a person who owns 15% or more of the outstanding shares of a corporation's voting stock, for three years after the person became an interested stockholder, unless:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• before the person became an interested stockholder, the board of directors approved either the transaction
resulting in a person becoming an interested stockholder or the business combination;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• upon consummating the transaction which resulted in the person 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 (excluding shares owned by persons who are both officers and directors of the corporation, and shares held by certain employee
stock ownership plans); or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• on or after the date the person becomes an interested stockholder, the business combination is approved by the
board of directors and at an annual or special meeting of stockholders by the affirmative vote of at least 66 2/3% of the corporation's outstanding voting stock which is not owned by the interested stockholder.

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

**Transfer Agent and Registrar** 

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

##### [**Table of Contents**](#toc)
**DESCRIPTION OF DEPOSITARY SHARES** 

We may issue preferred stock either separately or represented by depositary shares. We may also, at our option, issue fractional shares of preferred stock rather than full shares of preferred stock. If we exercise this option, we will issue receipts for depositary shares, and each of these depositary shares will represent a fraction (to be set forth in the prospectus supplement relating to such depositary shares) of a share of a particular series of preferred stock.

The shares of any series of preferred stock represented by the depositary shares will be deposited under a deposit agreement between us and a bank or trust company selected by us. The depositary will have its principal office in the United States and a combined capital and surplus of at least $50,000,000. Subject to the terms of the deposit agreement, each owner of a depositary share will be entitled, in proportion to the applicable share or fraction thereof represented by the depositary share, to all of the rights and preferences of the preferred stock represented thereby. Those rights may include dividend, voting, redemption, conversion and liquidation rights. The depositary shares will be evidenced by depositary receipts issued under a deposit agreement.

We will describe the material terms of the deposit agreement, the depositary shares and the depositary receipts in a prospectus supplement relating to the depositary shares. You should also refer to the forms of the deposit agreement and depositary receipts that will be filed with the SEC in connection with the offering of the specific depositary shares.

##### [**Table of Contents**](#toc)
**DESCRIPTION OF WARRANTS** 

This section describes the general terms and provisions of the warrants. A prospectus supplement will describe the specific terms of the warrants offered through that prospectus supplement and any general terms outlined in this section that will not apply to those warrants.

We may issue warrants for the purchase of common stock, preferred stock or depositary shares. Warrants may be issued alone or together with common stock, preferred stock or depositary shares offered by any prospectus supplement and may be attached to or separate from those securities. Each series of warrants will be issued under a separate warrant agreement between us and a bank or trust company, as warrant agent, which will be described in the applicable prospectus supplement. The securities warrant agent will act solely as our agent in connection with the warrants and will not act as an agent or trustee for any holders of warrants.

We have summarized the material terms and provisions of the warrant agreements and warrants in this section. We will file the form of warrant agreement for common stock (including the form of warrant), the form of warrant agreement for preferred stock (including the form of warrant), and the form of warrant agreement for depositary shares (including the form of warrant) with the SEC either as an exhibit to an amendment to the registration statement of which this prospectus is a part, or as an exhibit to a Current Report on Form 8-K. You should read the applicable forms of warrant agreement and warrant certificate for additional information before you buy any warrants.

**General** 

If we offer warrants, the applicable prospectus supplement will identify the warrant agent and describe the terms of the warrants we offer, the warrant agreement relating to the warrants and the certificates representing the warrants, including the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the title of the warrants;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the aggregate number of warrants;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the price or prices at which the warrants will be issued;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the currency or currencies, including composite currencies or currency units, in which the price of the warrants
may be payable if not payable in U.S. dollars;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the designation, number or aggregate principal amount, currency of denomination and payment, and terms of the
securities purchasable upon exercise of the warrants, and the procedures and conditions relating to the exercise of the warrants;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if applicable, the designation and terms of any related securities with which the warrants are issued with the
warrants and the number of warrants issued with each security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if applicable, the date on and after which the warrants and the related securities will be separately
transferable;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the principal amount of securities purchasable upon exercise of one warrant, and the price at and the currency in
which the principal amount of such securities may be purchased upon such exercise;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the date on which the right to exercise the warrants shall commence and the date on which the right to exercise
shall expire;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the maximum or minimum number of warrants that may be exercised at any time;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if applicable, the United States federal income tax considerations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• whether the warrants will be issued in registered or bearer form; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any other terms of the warrants.

------

##### [**Table of Contents**](#toc)
You may, at the corporate trust offices of the warrant agent or any other office indicated in the applicable prospectus supplement:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• exchange warrant certificates for new warrant certificates of different denominations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if the warrant certificates are in registered form, present them for registration of transfer; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• exercise warrant certificates.

**Exercise of Warrants** 

Each warrant will entitle the holder of the warrant to purchase at the exercise price set forth in the applicable prospectus supplement the principal amount of common stock, preferred stock or depositary shares, or combination thereof, being offered. Holders may exercise warrants at any time up to the close of business on the expiration date set forth in the applicable prospectus supplement. After the close of business on the expiration date, unexercised warrants are void. Holders may exercise warrants as set forth in the prospectus supplement relating to the warrants being offered.

Until holders exercise their warrants to purchase our common stock, preferred stock, or depositary shares, or combination thereof, holders will not have any rights as a holder of our common stock, preferred stock or depositary shares, as the case may be, by virtue of their ownership of warrants.

------

##### [**Table of Contents**](#toc)
**DESCRIPTION OF PURCHASE CONTRACTS** 

The following is a general description of the terms of the purchase contracts we may issue from time to time. The applicable prospectus supplement will describe the terms of any purchase contracts and, if applicable, prepaid purchase contracts. The description in the prospectus supplement will be qualified in its entirety by reference to (1) the purchase contracts, (2) the collateral arrangements and depositary arrangements, if applicable, relating to such purchase contracts and (3) if applicable, the prepaid purchase contracts and the document pursuant to which such prepaid purchase contracts will be issued.

We may issue purchase contracts, including contracts obligating holders to purchase from us, and obligating us to sell to holders, a fixed or varying number of shares of common stock, preferred stock or depositary shares at a future date or dates. The consideration may be fixed at the time that the purchase contracts are issued or may be determined by reference to a specific formula set forth in the purchase contracts. Any purchase contract may include anti-dilution provisions to adjust the number of shares issuable pursuant to such purchase contract, as applicable, upon the occurrence of certain events.

------

##### [**Table of Contents**](#toc)
**DESCRIPTION OF UNITS** 

We may, from time to time, issue units comprised of one or more of the other securities described in this prospectus in any combination. A prospectus supplement will describe the specific terms of the units offered under that prospectus supplement, and any special considerations, including tax considerations, applicable to investing in those units. You must review the applicable prospectus supplement and any applicable unit agreement for a full understanding of the specific terms of any units. We will incorporate by reference into the registration statement of which this prospectus is a part the form of unit agreement, including a form of unit certificate, if any, that describes the terms of the series of units we are offering. While the terms we have summarized below will generally apply to any future units that we may offer under this prospectus, we will describe the particular terms of any series of units that we may offer in more detail in the applicable prospectus supplement and incorporated documents. The terms of any units offered under a prospectus supplement may differ from the terms described below.

**General** 

Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security. The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately, at any time, or at any time before a specified date.

As specified in the applicable prospectus supplement, we may issue units consisting of one or more of the other securities described in this prospectus in any combination. In addition, we will describe in the applicable prospectus supplement and any incorporated documents the terms of any series of units we issue, including the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the designation and terms of the units and of the securities comprising the units, including whether and under
what circumstances those securities may be held or transferred separately;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• whether we will apply to have the units traded on a securities exchange or securities quotation system;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if applicable, any material United States federal income tax consequences;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• how, for United States federal income tax purposes, the purchase price paid for the units is to be allocated
among the component securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any provisions of the governing unit agreement that differ from those described below;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any provisions for the issuance, payment, settlement, transfer, or exchange of the units or of the securities
comprising the units; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any other information we think is important about the units.

The provisions described in this section, as well as those described under the other sections describing the securities offered by this prospectus, will apply to each unit and to any of such other securities included in each unit.

**Issuance in Series** 

We may issue units in such amounts and in such numerous distinct series as we determine.

**Enforceability of Rights by Holders of Units** 

Each unit agent will act solely as our agent under the applicable unit agreement and will not assume any obligation or relationship of agency or trust with any holder of any unit. A single bank or trust company may act

------

##### [**Table of Contents**](#toc)
as unit agent for more than one series of units. A unit agent will have no duty or responsibility in case of any default by us under the applicable unit agreement or unit, including any duty or responsibility to initiate any proceedings at law or otherwise, or to make any demand upon us. Any holder of a unit, without the consent of the related unit agent or the holder of any other unit, may enforce by appropriate legal action its rights as holder under any security included in the unit.

**Title** 

We, the unit agent, and any of their agents may treat the registered holder of any unit certificate as an absolute owner of the units evidenced by that certificate for any purposes and as the person entitled to exercise the rights attaching to the units so requested, despite any notice to the contrary.

##### [**Table of Contents**](#toc)
**PLAN OF DISTRIBUTION** 

**General** 

We, and/or selling securityholders, if applicable, may sell the applicable securities offered by this prospectus from time to time in one or more transactions, including without limitation:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• directly to one or more purchasers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• through agents;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to or through underwriters, brokers or dealers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• through a combination of any of these methods; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any other method permitted pursuant to applicable law.

A distribution of the securities offered by this prospectus may also be effected through the issuance of derivative securities, including without limitation, warrants, subscriptions, exchangeable securities, forward delivery contracts and the writing of options.

In addition, the manner in which we, and/or selling securityholders, if applicable, may sell some or all of the securities covered by this prospectus, include, without limitation, through:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a block trade in which a broker-dealer will attempt to sell as agent, but may position or resell a portion of the
block, as principal, in order to facilitate the transaction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• purchases by a broker-dealer, as principal, and resale by the broker-dealer for its account;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ordinary brokerage transactions and transactions in which a broker solicits purchasers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• privately negotiated transactions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• settlement of short sales;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• transactions through broker-dealers to sell a specified number of such securities at a stipulated price per
security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• an exchange distribution in accordance with the rules of the applicable exchange;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if applicable, a distribution in-kind to a selling securityholder's
direct or indirect partners, members or equity holders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a combination of any such methods of sale; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any other method permitted pursuant to applicable law.

As described above, if applicable, a selling securityholder that is an entity may elect to make a pro rata in-kind distribution of securities held by it to its direct or indirect members, partners or equity holders pursuant to the registration statement of which this prospectus is a part by delivering a prospectus, as amended or supplemented. To the extent that such members, partners or equity holders are not affiliates of ours, such members, partners or equity holders would thereby receive freely tradeable securities pursuant to the distribution under this prospectus. To the extent a distributee is an affiliate of ours (or to the extent otherwise required by law), we may file a prospectus supplement to permit the distributees to use the prospectus to resell the securities acquired in the distribution. The selling securityholders, if applicable, may also sell securities under Rule 144 or any other exemption from registration under the Securities Act, if available, rather than under this prospectus. There can be no assurance that the selling securityholders, if applicable, will sell any or all of the securities registered pursuant to the registration statement of which this prospectus forms a part. The selling securityholders, if applicable, may also transfer securities in other circumstances, in which case the transferees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.

------

##### [**Table of Contents**](#toc)
We, and/or selling securityholders, if applicable, may also enter into hedging transactions. For example, we, and/or selling securityholders, if applicable, may:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• enter into transactions with a broker-dealer or affiliate thereof in connection with which such broker-dealer or
affiliate will engage in short sales of the common stock pursuant to this prospectus, in which case such broker-dealer or affiliate may use shares of common stock received from us, and/or selling securityholders, if applicable, to close out its
short positions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• sell securities short and redeliver such shares to close out such short positions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• enter into option or other types of transactions that require us, and/or selling securityholders, if applicable,
to deliver common stock to a broker-dealer or an affiliate thereof, who will then resell or transfer the common stock under this prospectus; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• loan or pledge the common stock to a broker-dealer or an affiliate thereof, who may sell the loaned shares or, in
an event of default in the case of a pledge, sell the pledged shares pursuant to this prospectus.

In addition, we, and/or selling securityholders, if applicable, 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 the applicable securities covered by and pursuant to this prospectus and an applicable prospectus supplement. If so, the third party may use securities borrowed from us, and/or selling securityholders, if applicable, or others to settle such sales and may use securities received from us, and/or selling securityholders, if applicable, to close out any related short positions. We, and/or selling securityholders, if applicable, may also loan or pledge securities covered by this prospectus and an applicable 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 the applicable prospectus supplement.

A prospectus supplement with respect to each offering of securities will state the terms of the offering of the securities, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the name or names of any underwriters or agents and the amounts of securities underwritten or purchased by each
of them if any;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the public offering price or purchase price of the securities and the net proceeds to be received by us, and/or
selling securityholders, if applicable, from the sale;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any delayed delivery arrangements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any underwriting discounts or agency fees and other items constituting underwriters' or agents'
compensation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any discounts or concessions allowed or reallowed or paid to dealers; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any securities exchange or markets on which the securities may be listed.

The offer and sale of the securities described in this prospectus by us, and/or selling securityholders, if applicable, the underwriters or the third parties described above may be effected from time to time in one or more transactions, including privately negotiated transactions, either:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• at a fixed price or prices, which may be changed;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• at market prices prevailing at the time of sale;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• at prices related to the prevailing market prices; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• at negotiated prices.

------

##### [**Table of Contents**](#toc)
We will not receive any of the proceeds from any offering by a selling securityholder. Unless otherwise agreed with any selling securityholder, we will bear costs relating to all of the securities being registered under the registration statement of which this prospectus forms a part.

To the extent required, this prospectus may be amended or supplemented from time to time to describe a specific plan of distribution.

**Underwriting Compensation** 

Any public offering price and any fees, discounts, commissions, concessions or other items constituting compensation allowed or reallowed or paid to underwriters, dealers or agents may be changed from time to time. Underwriters, dealers and agents and remarketing firms that participate in the distribution of the offered securities may be "underwriters" as defined in the Securities Act. Any discounts or commissions they receive from us, and/or selling securityholders, if applicable, and any profits they receive on the resale of the offered securities may be treated as underwriting discounts and commissions under the Securities Act. We will identify any underwriters, agents or dealers and describe their fees, commissions or discounts in the applicable prospectus supplement.

**Underwriters and Agents** 

If underwriters are used in a sale, they will acquire the offered securities for their own account. The underwriters may resell the offered securities in one or more transactions, including negotiated transactions. These sales may be made at a fixed public offering price or prices, which may be changed, at market prices prevailing at the time of the sale, at prices related to such prevailing market price or at negotiated prices. We, and/or selling securityholders, if applicable, may offer the securities to the public either through an underwriting syndicate represented by one or more managing underwriters or through one or more underwriter(s). The underwriters in any particular offering will be identified in the applicable prospectus supplement.

Unless otherwise specified in connection with any particular offering of securities, the obligations of the underwriters to purchase the offered securities will be subject to certain conditions contained in an underwriting agreement that we, and/or selling securityholders, if applicable, will enter into with the underwriters at the time of the sale to them. The underwriters will be obligated to purchase all of the securities of the series offered if any of the securities are purchased, unless otherwise specified in connection with any particular offering of securities. Any initial offering price and any discounts or concessions allowed, reallowed or paid to dealers may be changed from time to time.

Securities may be sold directly by us, and/or selling securityholders, if applicable, or through agents designated by us, and/or selling securityholders, if applicable, from time to time. Any agent involved in the offer or sale of the securities in respect of which this prospectus and a prospectus supplement is delivered will be named, and any commissions payable by us, and/or selling securityholders, if applicable, to such agent will be set forth, in the prospectus supplement. Unless otherwise indicated in the prospectus supplement, any such agent will be acting on a best efforts basis for the period of its appointment.

In connection with offerings made through underwriters or agents, we may enter into agreements with such underwriters or agents pursuant to which we receive our outstanding securities in consideration for the securities being offered to the public for cash. In connection with these arrangements, the underwriters or agents may also sell securities covered by this prospectus to hedge their positions in these outstanding securities, including in short sale transactions. If so, the underwriters or agents may use the securities received from us under these arrangements to close out any related open borrowings of securities.

Because the selling securityholders, if applicable, may be deemed to be "underwriters" within the meaning of Section 2(11) of the Securities Act, they may be subject to the prospectus delivery requirements of the

------

##### [**Table of Contents**](#toc)
Securities Act, including Rule 172 thereunder. We will make copies of this prospectus available to the selling securityholders, if applicable, and will inform the selling securityholders, if applicable, of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).

**Dealers** 

We, and/or selling securityholders, if applicable, may sell the offered securities to dealers as principals. We, and/or selling securityholders, if applicable, may negotiate and pay dealers' commissions, discounts or concessions for their services. The dealer may then resell such securities to the public either at varying prices to be determined by the dealer or at a fixed offering price agreed to with us, and/or selling securityholders, if applicable, at the time of resale. Dealers engaged by us, and/or selling securityholders, if applicable, may allow other dealers to participate in resales.

**Direct Sales** 

We, and/or selling securityholders, if applicable, may choose to sell the offered securities directly to multiple purchasers or a single purchaser. In this case, no underwriters or agents would be involved.

**At-the-Market Offerings** 

We may also sell the securities offered by any applicable prospectus supplement in "at-the-market offerings" within the meaning of Rule 415 of the Securities Act, to or through a market maker or into an existing trading market, on an exchange or otherwise.

**Institutional Purchasers** 

We, and/or selling securityholders, if applicable, may authorize agents, dealers or underwriters to solicit certain institutional investors to purchase offered securities on a delayed delivery basis pursuant to delayed delivery contracts providing for payment and delivery on a specified future date. The applicable prospectus supplement will provide the details of any such arrangement, including the offering price and commissions payable on the solicitations.

We, and/or selling securityholders, if applicable, will enter into such delayed contracts only with institutional purchasers that we, and/or selling securityholders, if applicable, approve. These institutions may include commercial and savings banks, insurance companies, pension funds, investment companies and educational and charitable institutions.

**Indemnification; Other Relationships** 

We, and/or selling securityholders, if applicable, may agree to indemnify underwriters, dealers and agents against certain civil liabilities, including liabilities under the Securities Act and to make contribution to them in connection with those liabilities. Underwriters, dealers and agents, and their affiliates, may engage in transactions with, or perform services for us, and/or selling securityholders, if applicable, and our or their affiliates, in the ordinary course of business, including commercial banking transactions and services.

**Market Making, Stabilization and Other Transactions** 

Each series of securities will be a new issue of securities and will have no established trading market other than the common stock which is listed on the NYSE. If the offered securities are traded after their initial issuance, they may trade at a discount from their initial offering price, depending upon prevailing interest rates, the market for similar securities and other factors. While it is possible that an underwriter could inform us that it

------

##### [**Table of Contents**](#toc)
intends to make a market in the offered securities, such underwriter would not be obligated to do so, and any such market-making could be discontinued at any time without notice. Therefore, no assurance can be given as to whether an active trading market will develop for the offered securities. We have no current plans for listing of the preferred stock on any securities exchange or quotation system; any such listing with respect to any preferred stock will be described in the applicable prospectus supplement.

In connection with any offering of common stock, preferred stock or securities that provide for the issuance of shares of our common stock upon conversion, exchange or exercise, as the case may be, the underwriters may purchase and sell shares of our common stock or preferred stock in the open market. These transactions may include short sales, syndicate covering transactions and stabilizing transactions. Short sales involve syndicate sales of common stock in excess of the number of shares to be purchased by the underwriters in the offering, which creates a syndicate short position. "Covered" short sales are sales of shares made in an amount up to the number of shares represented by the underwriters' over-allotment option. In determining the source of shares to close out the covered syndicate short position, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase shares through the over-allotment option. Transactions to close out the covered syndicate short involve either purchases of the common stock in the open market after the distribution has been completed or the exercise of the over-allotment option. The underwriters may also make "naked" short sales of shares in excess of the over-allotment option. The underwriters must close out any naked short position by purchasing shares of common stock in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the shares in the open market after pricing that could adversely affect investors who purchase in the offering. Stabilizing transactions consist of bids for or purchases of shares in the open market while the offering is in progress for the purpose of pegging, fixing or maintaining the price of the securities.

In connection with any offering, the underwriters may also engage in penalty bids. Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when the securities originally sold by the syndicate member are purchased in a syndicate covering transaction to cover syndicate short positions. Stabilizing transactions, syndicate covering transactions and penalty bids may cause the price of the securities to be higher than it would be in the absence of the transactions. The underwriters may, if they commence these transactions, discontinue them at any time.

The validity of the securities and certain other matters will be passed upon for us by Kirkland & Ellis LLP, Houston, Texas. Certain legal matters will be passed upon for any underwriters, dealers or agents by the law firm identified as counsel to such underwriters, dealers or agents in the applicable prospectus supplement.

**Item 15. Indemnification of Directors and Officers** 

Under our restated certificate of incorporation, as amended (our "Certificate of Incorporation"), and bylaws (and in accordance with Section 145 of the Delaware General Corporation Law (the "DGCL")), we will indemnify to the fullest extent permitted by the DGCL any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, including civil, criminal, administrative, investigative or other proceedings, by reason of the fact that the person is or was a director, officer or employee of the Company, or is or was serving in that capacity or as an agent at the request of the Company for another entity.

Section 145(a) of the DGCL provides, in general, that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation), because he or she is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding, if he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful.

Section 145(b) of the DGCL provides, in general, that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor because the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys' fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation, except that no indemnification shall be made with

------

##### [**Table of Contents**](#toc)
respect to any claim, issue, or matter as to which he or she shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery of the State of Delaware or other adjudicating court determines that, despite the adjudication of liability but in view of all of the circumstances of the case, he or she is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or other adjudicating court shall deem proper.

Section 145(e) of the DGCL provides that expenses (including attorneys' fees) incurred by an officer or director in defending any civil, criminal, administrative or investigative action, suit or proceeding may be paid by the corporation in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of such director or officer to repay such amount if it shall ultimately be determined that such person is not entitled to be indemnified by the corporation as authorized by Section 145 of the DGCL.

Section 145(e) of the DGCL further provides that such expenses (including attorneys' fees) incurred by former directors and officers or other employees or agents of the corporation may be so paid upon such terms and conditions as the corporation deems appropriate.

Section 145(g) of the DGCL provides, in general, that a corporation may purchase and maintain insurance on behalf of any person who is or was a director, officer, employee, or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee, or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against such person and incurred by such person in any such capacity, or arising out of his or her status as such, whether or not the corporation would have the power to indemnify the person against such liability under Section 145 of the DGCL.

Our Certificate of Incorporation provides that, to the fullest extent permitted by the DGCL, our directors shall not be personally liable to us or our stockholders for monetary damages for breach of fiduciary duty as a director. Under Section 102(b)(7) of the DGCL, the personal liability of a director to the corporation or its stockholders for monetary damages for breach of fiduciary duty can be limited or eliminated except (1) for any breach of the director's duty of loyalty to the corporation or its stockholders; (2) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law; (3) under Section 174 of the DGCL (relating to unlawful payment of dividend or unlawful stock purchase or redemption) or (4) for any transaction from which the director derived an improper personal benefit.

Our indemnity covers expenses, judgments, fines and amounts paid or to be paid in settlement actually and reasonably incurred in connection with the defense or settlement of an action, suit or proceeding if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to our best interest and, with respect to any criminal action or proceeding, had no reasonable cause to believe that his or her conduct was unlawful. We will indemnify a person in a derivative action under the same conditions, except that no indemnification is permitted without judicial approval if the person is adjudged to be liable to us in performance of his or her duty. Derivative actions are actions by us or in our right to procure a judgment in our favor. Our agents may be similarly indemnified at the discretion of our board of directors.

All of our directors and officers are covered by an insurance policy that we maintain against specified liabilities for actions taken in their capacities as such, including liabilities under the Securities Act.

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

Reference is made to the forms of Underwriting Agreement, which will be included or incorporated by reference as an exhibit to this Registration Statement for provisions regarding indemnification of the Registrant's officers, directors and controlling persons against specified liabilities.

**Item 17. Undertakings** 

(a) The undersigned Registrant hereby undertakes:

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 subparagraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) do not apply if the registration statement is on Form S-3, Form SF-3, or Form F-3 and the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the Registrant pursuant to section 13 or section 15(d) of the 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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.

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(A) 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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(B) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration
statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by section 10(a) of the Securities Act 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

------

##### [**Table of Contents**](#toc)
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; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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:

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 the purpose of determining any liability under the
Securities Act of 1933, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual
report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in this 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 Commission such indemnification is against public policy as expressed in the
Securities Act of 1933 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 of 1933 and will be governed by the final
adjudication of such issue.

Re: Registration Statement on Form S-3

Ladies and Gentlemen:

We are issuing this opinion in our capacity as special legal counsel to Northern Oil and Gas, Inc., a Delaware corporation (the "<u>Company</u>"), in connection with the proposed registration by the Company under the Securities Act of 1933, as amended (the "<u>Securities Act</u>"), on a Registration Statement on Form S-3ASR (such Registration Statement, as amended or supplemented, is hereinafter referred to as the "<u>Registration Statement</u>"), filed with the Securities and Exchange Commission (the "<u>Commission</u>") on or about June 1, 2026, for the offer and sale from time to time, pursuant to Rule 415 under the Securities Act, of an unspecified amount of the following securities: (i) common stock, par value $0.001 per share, of the Company (the "<u>Common Stock</u>"), (ii) preferred stock, par value $0.001 per share, of the Company (the "<u>Preferred Stock</u>"), (iii) Preferred Stock represented by depositary shares (the "<u>Depositary Shares</u>"), (iv) warrants to purchase the Common Stock, Preferred Stock, Depositary Shares or any combination of those securities (the "<u>Warrants</u>"), (v) contracts obligating holders to purchase from the Company, and/or the Company to sell to the holders, a certain amount of Common Stock, Preferred Stock or Depositary Shares at a future date or dates (the "<u>Purchase Contracts</u>") and (vi) units consisting of one or more shares of Common Stock, shares of Preferred Stock, Depositary Shares, Warrants, Purchase Contracts or any combination of such securities (the "<u>Units</u>"). The Warrants, the Common Stock, the Preferred Stock, the Depositary Shares, the Purchase Contracts and the Units (collectively, the "<u>Securities</u>") may be issued by the Company either together or separately in connection with an offering or offerings from time to time pursuant to the Registration Statement and will be offered on terms set forth in the Registration Statement and in the prospectus contained in the Registration Statement (the "<u>Prospectus</u>") and in amounts, at prices and on other terms to be determined by the Company at the time of offering and to be set forth in an amendment or amendments to the Registration Statement and the Prospectus and in one or more supplements to the Prospectus (each, a "<u>Prospectus Supplement</u>").

You have advised us that: (i) the Warrants will be issued under one or more warrant agreements (each, a "<u>Warrant Agreement</u>"), each to be between the Company and a financial institution identified therein as warrant agent (each, a "<u>Warrant Agent</u>"); (ii) the Depositary Shares will be issued under one or more deposit agreements (each, a "<u>Deposit Agreement</u>"), each to be between the Company and a financial institution identified therein as the depositary (the "<u>Depositary</u>"); (iii) the Purchase Contracts will be issued under one or more purchase contracts agreements by and among the Company and the other parties named therein (each, a "<u>Purchase Contracts Agreement</u>"); and (iv) the Units will be issued under one or more unit agreements (each, a "<u>Unit Agreement</u>"). Each Warrant Agreement, each Deposit Agreement, each Unit Agreement and each Purchase Contract Agreement shall be referred to herein as a "<u>Governing Document</u>." Each Depositary and each Warrant Agent shall be referred to herein as a "<u>Governing Document Counterparty</u>."

In connection with the registration of the Securities, we have examined originals, or copies certified or otherwise identified to our satisfaction, of such documents, corporate records and other instruments as we have deemed necessary for the purposes of this opinion, including: (i) the organizational documents of the Company, (ii) minutes and records of the corporate proceedings of the Company and (iii) the Registration Statement and the exhibits thereto.
