This prospectus, including information in documents incorporated by reference, contains forward-looking statements within the meaning of the federal securities laws.

These forward-looking statements may be identified by their use of terms and phrases such as “may,” “expect,” “estimate,” “project,” “plan,” “objective,” “believe,” “predict,” “intend,” “achievable,” “anticipate,” “will,” “continue,” “potential,” “should,” “could” and similar terms and phrases. Although we believe that the expectations reflected in forward-looking statements are reasonable, they do involve certain assumptions, risks and uncertainties. Actual results could differ materially from those anticipated in these forward-looking statements. Readers should consider carefully the risks described under the “Risk Factors” section of this report and other sections of this report which describe factors that could cause our actual results to differ from those anticipated in forward-looking statements, which include, but are not limited to, the following factors:

●

volatility in prices for oil, natural gas and natural gas liquids (“NGLs”);

●

our ability to generate sufficient cash flow from operations, borrowings or other sources to enable us to fund our operations, satisfy our obligations and develop our undeveloped acreage positions;

●

contractual limitations that affect our management’s discretion in managing our business, including covenants that, among other things, limit our ability to incur debt, make investments and pay cash dividends;

our indebtedness, which may increase in the future, and higher levels of indebtedness can make us more vulnerable to economic downturns and adverse developments in our business;

●

our ability to replace our oil and natural gas reserves and production;

●

the presence or recoverability of estimated oil and natural gas reserves attributable to our properties and the actual future production rates and associated costs of producing those oil and natural gas reserves;

●

our ability to successfully develop our large inventory of undeveloped acreage;

●

the cost and availability of goods and services, such as drilling rigs, fracture stimulation services and tubulars, which may be subject to inflation caused by labor shortages, supply shortages and increased demand, tariffs and other inflationary pressures;

●

drilling and operating risks, including accidents, equipment failures, fires, and releases of toxic or hazardous materials, such as hydrogen sulfide (H₂S), which can result in injury, loss of life, pollution, property damage and suspension of operations;

●

senior management’s ability to execute our plans to meet our goals;

●

access to and availability of water, sand and other treatment materials to carry out fracture stimulations in our completion operations;

●

the possibility that our industry may be subject to future regulatory or legislative actions (including, but not limited to, additional taxes and changes in environmental regulations);

Table of Contents

●

access to adequate gathering systems, processing and treating facilities and transportation take-away capacity to move our production to marketing outlets to sell our production at market prices;

divestitures could negatively impact our business and our results of operations may be adversely affected if we fail to manage and complete divestitures;

●

the potential for production decline rates for our wells to be greater than we expect;

●

competition, including competition for acreage in our resource play;

●

environmental risks, such as accidental spills of toxic or hazardous materials, and the potential for environmental liabilities;

social unrest, political instability or armed conflict in major oil and natural gas producing regions outside the United States (the “U.S.”), such as the political situation in Venezuela, the ongoing conflict between Ukraine and Russia and the war in the Middle East, and acts of terrorism or sabotage;

●

impacts of climate regulations or lawsuits;

●

general economic conditions, whether internationally, nationally or in the regional and local market areas in which we do business, may be less favorable than expected, including the possibility that economic conditions in the United States will worsen and that capital markets are disrupted, which could adversely affect demand for oil and natural gas and make it difficult to access capital;

●

impacts and potential risks related to actual or anticipated pandemics, including any associated impact to our operations, financial results, liquidity, contractors, customers, employees and vendors;

●

impacts and potential risks of extreme weather;

●

other economic, competitive, governmental, regulatory, legislative, including federal and state regulations and laws, geopolitical and technological factors that may negatively impact our business, operations or oil and natural gas prices;

●

our insurance coverage may not adequately cover all losses that we may sustain; and

All forward-looking statements are expressly qualified in their entirety by the cautionary statements in this paragraph and elsewhere in this prospectus and the documents incorporated by reference. Any forward-looking statements speak only as of this prospectus. Other than as required under the securities laws, we do not assume a duty to update these forward-looking statements, whether as a result of new information, subsequent events or circumstances, changes in expectations or otherwise.

Overview

We are an independent energy company focused on the acquisition, production, exploration and development of onshore liquids-rich oil and natural gas assets in the U.S. Our properties and drilling activities are currently focused in the Delaware Basin, where we have an extensive drilling inventory that we believe offers attractive long-term economics.

Our working interests in 39,968 net acres in the Delaware Basin as of December 31, 2025 are in Pecos, Reeves, Ward and Winkler Counties, Texas. This resource play is characterized by high oil and liquids-rich natural gas content in thick, continuous sections of source rock that can provide repeatable drilling opportunities and significant initial production rates. Our primary targets in this area are the Wolfcamp and Bone Spring formations. As of December 31, 2025, we had 82 operated wells producing in this area in addition to minor working interests in 22 non-operated wells. Our average daily net production for the year ended December 31, 2025 was 12,096 Boe/d.

At December 31, 2025, our estimated total proved oil and natural gas reserves were approximately 59.7 MMBoe, consisting of 31.8 MMBbls of oil, 11.6 MMBbls of NGLs and 97.5 Bcf of natural gas, as prepared by our independent reserve engineering firm, Netherland, Sewell & Associates, Inc. (“NSAI”). Reserves were prepared using a crude oil price of West Texas Intermediate (“WTI”) of $66.01 per Bbl and a Henry Hub natural gas price of $3.39 per MMBtu, based on the preceding 12-month first day of the month average spot prices as required by the Securities and Exchange Commission (the “SEC”). Approximately 60% of our estimated proved reserves were classified as proved developed and we maintain operational control of 99.8% of our estimated proved reserves as of December 31, 2025.

On December 18, 2025, we entered into an agreement of sale and purchase with MCM Delaware Resources, LLC (“MCM”) to sell substantially all of our oil and natural gas properties and related assets in the West Quito Draw area located in the Southern Delaware Basin in Ward County, Texas (the “West Quito Assets”) for a total sales price of approximately $62.6 million, subject to adjustment for accounting between the effective date of December 1, 2025 and the closing date and other customary adjustments (the “West Quito Divestiture”). The West Quito Divestiture closed on February 24, 2026 for an adjusted sales price of $60.1 million. The West Quito Assets include approximately 6,100 net acres in Ward County, Texas which contributed approximately 15% of our annual production for the year ended December 31, 2025 and accounted for approximately 6.0 MMboe, or approximately 10%, of our proved reserves at December 31, 2025.

Recent Developments

Private Placement

On March 3, 2026, the Company entered into a securities purchase agreement (the “Securities Purchase Agreement”) with an institutional investor (“Institutional Investor”). Pursuant to the Securities Purchase Agreement, the Company agreed to sell and the Institutional Investor agreed to purchase from the Company, in a private placement offering, 1,800,000 shares (the “Shares”) of the Company’s common stock, par value $0.0001 per share (the “Common Stock”) at a purchase price of $5.50 per Share and pre-funded warrants to purchase up to 927,273 shares of Common Stock (the “Pre-Funded Warrants”) at a purchase price of $5.4999 per Pre-Funded Warrant share, for aggregate gross proceeds of $15.0 million. The Pre-Funded Warrants have an exercise price of $0.0001 per share. The offering closed on March 4, 2026, on satisfaction of customary closing conditions.

The Pre-Funded Warrants are exercisable immediately upon issuance and shall expire on March 4, 2033. The Pre-Funded Warrants may not be exercised to the extent such exercise would cause the holder to beneficially own more than 9.99% of the Company’s issued and outstanding shares of Common Stock.

The Securities Purchase Agreement has customary representations, warranties, covenants and closing conditions for a transaction of this nature. Pursuant to the Securities Purchase Agreement, for a period commencing upon the signing of the Securities Purchase Agreement, until 30 days after the effective date of the Registration Statement (as defined below), neither the Company nor any of its subsidiaries shall (i) issue, enter into any agreement to issue or announce the issuance or proposed issuance of any shares of Common Stock or Common Stock equivalents, or (ii) file any registration statement or any amendment or supplement thereto. The restrictions are subject to certain exceptions as described in the Securities Purchase Agreement. Further, for a period of 30 days following the effective date of the Registration Statement, the Company is also prohibited from effecting or entering into an agreement to effect any issuance by the Company or any of its subsidiaries of shares of Common Stock or Common Stock equivalents (or a combination of units thereof) involving a Variable Rate Transaction, as defined in the Securities Purchase Agreement.

In connection with the Securities Purchase Agreement, on March 3, 2026, the Company also entered into a registration rights agreement (the “Registration Rights Agreement”) with the Institutional Investor. Pursuant to the Registration Rights Agreement, the Company has filed a resale registration statement (the “Registration Statement”) with the SEC to register for resale the Shares and the shares of Common Stock underlying the Pre-Funded Warrants within 20 calendar days of the date of such agreement and use its reasonable best efforts to cause the registration statement to become effective within 45 calendar days of the date of the Registration Rights Agreement (or 75 days in the event of a “full review” by the SEC). The Registration Rights Agreement also contains indemnification provisions and other provisions customary for an agreement of this type and provides for liquidated damages to the Institutional Investor in the event the Company fails to comply with certain of its obligations thereunder. The Company is required to keep the Registration Statement effective until all of the shares registered thereunder have been sold pursuant to the Registration Statement or Rule 144 under the Securities Act of 1933, as amended (the “Securities Act”) or are saleable without restriction under Rule 144.

The securities issued in that private placement are not being registered for resale pursuant to this prospectus and are covered by a separate resale registration statement/prospectus.

Expansion of Monument Draw Position With Strategic Acquisition from Sundown

On March 10, 2026, the Company, together with a wholly owned subsidiary, entered into a Purchase and Sale Agreement (the “PSA”) with RoadRunner Resource Holding LLC (formerly Sundown Energy LP)

-7-

Table of Contents

(“Sundown”) to acquire approximately 7,090 net acres of oil and gas assets located in Ward County, Texas (the “Assets”). The transaction closed on March 19, 2026.

Pursuant to the PSA, the Company issued 485,000 shares of its common stock, par value $0.0001 per share (the “Purchase Price Shares”), to Sundown as consideration for the Assets.

The issuance of the Purchase Price Shares was made in reliance on Section 4(a)(2) of the Securities Act. The shares constituted “restricted securities” as defined in Rule 144 under the Securities Act and will be subject to transfer limitations, including a 60-day lock-up period.

Preferred Stock Conversion

On March 30, 2026, we issued 1,800,000 shares of our Common Stock to Luminus Energy Partners Master Fund, Ltd. (“Luminus”) upon the conversion of 7,803 shares of our Series A-2 Preferred Stock. The conversion was calculated in accordance with the terms of the Series A-2 Preferred Stock, including adjustments provided in respect of any Unpaid Dividend Accrual (as defined in our Certificate of Incorporation, as amended), and using a conversion price of $6.21 per share.

As previously disclosed, the Series A-2 Preferred Stock was issued, pursuant to that certain Purchase Agreement (the “Series A-2 Purchase Agreement”) entered into on December 15, 2023, by and among us and each of the purchasers set forth on Schedule A thereto (the “Series A-2 Purchasers” and the purchase and sale of such shares of Series A-2 Preferred Stock, the “Series A-2 Preferred Stock Transaction”).

The Series A-2 Purchasers, including Luminus, and/or their respective affiliates, consisted of our largest three (3) shareholders whose appointed representatives made up fifty percent (50%) of our board of directors. The Series A-2 Preferred Stock Transaction, including the Common Stock issuable upon the conversion of the Series A-2 Preferred Stock, was approved by our board of directors upon recommendation by a special committee of disinterested directors that was established to evaluate the proposed terms of the Series A-2 Preferred Stock Transaction.

Issuance of the Common Stock was undertaken in reliance upon an exemption from the registration requirements of the Securities Act of 1933, as amended, pursuant to Section 4(a)(2) thereof.

Our shares of Common Stock are listed on the NYSE American exchange under the symbol “BATL”.

Risk Factors

An investment in our securities involves a high degree of risk. Before making an investment decision, in addition to the risks and uncertainties discussed above under “Cautionary Statement Regarding Forward-Looking Statements,” 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.

The risks incorporated by reference in this prospectus are the material risks of which we are currently aware; however, they may not be the only risks that we may face. Additional risks and uncertainties not currently known to us or that we currently view as immaterial may also impair our business operations. Any of these risks could materially and adversely affect our business, financial condition, results of operations and cash flows. In that case, you may lose all or part of your investment. We may face additional risks and uncertainties that are not presently known to us, or that we currently deem immaterial.

The sale of a substantial number of shares of our common stock in the public market, including resale of the Shares issued to the Selling Securityholders and offers pursuant to a prospectus supplement to this prospectus, could adversely affect the prevailing market price for our common stock.

We are registering for resale 36,999,134 shares of Common Stock issued to the Selling Securityholders. Sales of substantial amounts of shares of our Common Stock in the public market, or the perception that such sales might occur, could adversely affect the market price of our Common Stock. We cannot predict if and when the Selling Securityholders may sell such shares in the public markets. Furthermore, we may offer up to $375 million of our securities pursuant to a prospectus supplement to this prospectus in the future. Any such issuances could result in substantial dilution to our existing stockholders and could cause our stock price to decline.

Use Of Proceeds

Unless otherwise specified in a prospectus supplement accompanying this prospectus, the net proceeds from the sale by us of the securities to which this prospectus relates will be used for general corporate purposes. General corporate purposes may include, without limitation, acquisitions, additions to working capital, capital expenditures and repayment or refinancing of debt. Net proceeds may be temporarily invested prior to use.

All of the shares of Registrable Securities offered by the Selling Securityholders pursuant to this prospectus will be sold by the Selling Securityholders for their account. We will not receive any of the proceeds from these sales.

We will bear the out-of-pocket costs, expenses and fees incurred in connection with the registration of shares of Common Stock to be sold by the Selling Securityholders pursuant to this prospectus. Other than registration-related expenses, the Selling Securityholders will bear their own broker or similar commissions payable with respect to any sales of their shares of Common Stock.

Selling Securityholders

The Selling Securityholders may from time to time offer and sell any or all of the shares of Common Stock being offered for resale by this prospectus, which consist of:

●

Up to 5,935,377 shares of Common Stock; and

●

Up to 31,063,757 shares of Common Stock underlying shares of Redeemable Convertible Preferred Stock issuable upon conversion of Redeemable Convertible Preferred Stock.

When we refer to the “Selling Securityholders” in this prospectus, we mean the persons listed in the table below, and the pledgees, donees, transferees, assignees, successors, designees and others who later come to hold any of the Selling Securityholders’ interest in the Registrable Securities other than through a public sale.

The table below lists the Selling Securityholders and other information regarding the beneficial ownership of the shares of Common Stock by the Selling Securityholders. This information has been obtained from the Selling Securityholders or in Schedules 13G or 13D and other public documents filed with the SEC. The second column lists the number of shares of Common Stock beneficially owned by the Selling Securityholders, based on their beneficial ownership of shares of Common Stock, as of April 15, 2026, assuming conversion of the Redeemable Convertible Preferred Stock, held by the Selling Securityholders on that date, without regard to any limitations on conversion, unless otherwise indicated. Further, shares of Common Stock issuable upon conversion of the Redeemable Convertible Preferred Stock may be offered only after issuance of shares of Common Stock upon conversion of the Redeemable Convertible Preferred Stock pursuant to the terms of the respective certificate of designations. Such estimations of shares of Common Stock issuable upon conversion of Redeemable Convertible Preferred Stock are as of April 4, 2026 in accordance with the applicable certificates of designations, including any adjustments applicable as of such date, and include an additional 4,625,909 shares of Common Stock that the Company has estimated in good faith as the maximum number of shares of Common Stock issuable upon conversion of the Redeemable Convertible Preferred Stock. The table below does not include the additional 4,625,909 shares.

The applicable percentage ownership of shares of Common Stock in the second and fifth columns is based on approximately 21,468,836 shares of Common Stock outstanding as of April 15, 2026 and assumes conversion of all outstanding Redeemable Convertible Preferred Stock. Information with respect to shares of Common Stock owned beneficially after the offering assumes the sale of all of the Registrable Securities. The Selling Securityholders may offer and sell some, all or none of their Registrable Securities, as applicable.

We have determined beneficial ownership in accordance with the rules of the SEC, which generally provide that a person has beneficial ownership of a security if he, she or it possesses sole or shared voting or investment power over that security or the right to acquire such power within 60 days. Except as indicated by the footnotes below, we believe, based on the information furnished to us, that the Selling Securityholders have sole voting and investment power with respect to all Registrable Securities that they beneficially own, subject to applicable community property laws. Except as otherwise described below, based on the information provided to us by the Selling Securityholders, the Selling Securityholders are not broker-dealers or affiliates of a broker dealer.

Please see the section titled “Plan of Distribution” for further information regarding the Selling Securityholders’ method of distributing these shares.

See “Use of Proceeds.”

We will not receive any of the proceeds from the sale of the Registrable Securities by the Selling Securityholders. We are required to pay all fees and expenses incident to the registration of the shares of Common Stock to be offered and sold pursuant to this prospectus. The Selling Securityholders will bear all commissions and discounts, if any, attributable to their sale of shares of Common Stock.

Once issued and upon effectiveness of the Registration Statement of which this prospectus forms a part, the shares of Common Stock beneficially owned by the Selling Securityholders covered by this prospectus may be offered and sold from time to time by the Selling Securityholders. The term “Selling Securityholders” includes donees, pledgees, transferees or other successors in interest selling shares of Common Stock received after the date of this prospectus from Selling Securityholders as a gift, pledge, partnership distribution or other transfer. Each Selling Securityholder will act independently of us in making decisions with respect to the timing, manner and size of each sale. Such sales may be made on one or more exchanges or in the over-the-counter market or otherwise, at prices and under terms then prevailing or at prices related to the then-current market price or in negotiated transactions. Each Selling Securityholder reserves the right to accept and, together with its respective agents, to reject, any proposed purchase of shares of Common Stock to be made directly or through agents. The Selling Securityholders and any of their permitted transferees may sell their shares of Common Stock offered by this prospectus on any stock exchange, market or trading facility on which the shares of Common Stock are traded or in private transactions.

The Selling Securityholders may use any one or more of the following methods when selling the shares of Common Stock offered by this prospectus:

●

purchases by a broker-dealer as principal and resale by such broker-dealer for its own account pursuant to this prospectus;

●

ordinary brokerage transactions and transactions in which the broker solicits purchasers;

●

block trades in which the broker-dealer so engaged will attempt to sell the shares of Common Stock as agent but may position and resell a portion of the block as principal to facilitate the transaction;

●

an over-the-counter distribution in accordance with the rules of the applicable exchange;

●

settlement of short sales entered into after the effective date of the registration statement of which this prospectus forms a part;

●

agreements with underwriters or broker-dealers to sell a specified number of the shares at a stipulated per share price;

●

in “at the market” offerings, as defined in Rule 415 under the Securities Act, at negotiated prices, at prices prevailing at the time of sale or at prices related to such prevailing market prices, including sales made directly on a national securities exchange or sales made through a market maker other than on an exchange or other similar offerings through sales agents;

●

directly to purchasers, including through a specific bidding, auction or other process or in privately negotiated transactions;

-14-

Table of Contents

●

through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

●

in underwritten offerings on a firm commitment or best efforts basis;

●

in exchange distributions in accordance with the rules of the applicable exchange;

●

by pledge to secure debts and other obligations;

●

through delayed delivery requirements;

●

through a combination of any of the above methods of sale; or

●

any other method permitted pursuant to applicable law.

In addition, the Selling Securityholders may elect to make an in-kind distribution of shares of Common Stock to their members, partners or shareholders pursuant to the Registration Statement of which this prospectus forms a part by delivering a prospectus with a plan of distribution. Such members, partners or shareholders would thereby receive freely tradeable securities pursuant to the distribution through a registration statement. To the extent a distributee is an affiliate of ours (or to the extent otherwise required by law), we may file a prospectus supplement in order to permit the distributees to use the prospectus to resell the shares of Common Stock acquired in the distribution.

The Selling Securityholders also may transfer the Registrable 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. Upon being notified by the Selling Securityholders that a donee, pledgee, transferee, other successor-in-interest intends to sell Registrable Securities, we will, to the extent required, promptly file a supplement to this prospectus to name specifically such person as a Selling Securityholder.

The Selling Securityholders may also sell the Registrable Securities under Rule 144 under the Securities Act, if available, rather than under this prospectus.

To the extent required, the Registrable Securities to be sold, the names of the Selling Securityholders, the respective purchase prices and public offering prices, the names of any agents, dealer or underwriter, any applicable commissions or discounts with respect to a particular offer will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the Registration Statement that includes this prospectus.

In connection with the sale of the Registrable Securities, the Selling Securityholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the Registrable Securities in the course of hedging the positions they assume. The Selling Securityholders may also sell the Registrable Securities short and deliver these shares of Common Stock to close out their short positions, or loan or pledge the Registrable Securities to broker-dealers that in turn may sell these shares. The Selling Securityholders may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares of Common Stock offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

In offering the shares of Common Stock covered by this prospectus, the Selling Securityholders and any underwriters, broker-dealers or agents who execute sales for the Selling Securityholders may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. Any discounts, commissions, concessions or profit they earn on any resale of those shares of Common Stock may be underwriting discounts and commissions under the Securities Act (it being understood that the Selling Securityholders named herein shall not be deemed to be underwriters solely as a result of their participation in this offering).

Table of Contents

We have agreed to indemnify the Selling Securityholders against certain liabilities, including liabilities under the Securities Act.

In order to comply with the securities laws of certain states, if applicable, the shares of Common Stock must be sold in such jurisdictions only through registered or licensed brokers or dealers. In addition, in certain states, the shares of Common Stock may not be sold unless they have been registered or qualified for sale in such state or an exemption from the registration or qualification requirement is available and is complied with. The anti-manipulation rules under the Exchange Act may apply to sales of the securities in the market and to the activities of the Selling Securityholders and their affiliates. Furthermore, Regulation M may restrict the ability of any person engaged in the distribution of the securities to engage in market-making activities for the particular securities being distributed for a period of up to five business days before the distribution. The restrictions may affect the marketability of the securities and the ability of any person or entity to engage in market-making activities for the securities. In addition, to the extent applicable we will make copies of this prospectus (as it may be supplemented or amended from time to time) available to the Selling Securityholders for the purpose of satisfying the prospectus delivery requirements of the Securities Act. The Selling Securityholders may indemnify any broker-dealer that participates in transactions involving the sale of the shares against certain liabilities, including liabilities arising under the Securities Act.

●

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

●

We may enter into derivative, hedging, forward sale, option or other types of transactions with third parties, or sell securities not covered by this prospectus to third parties, through a stock exchange, including block trades or ordinary broker’s transactions, or through broker-dealers acting either as principal or agent, or through an underwritten public offering, through privately negotiated transactions or through a combination of any such methods of sale. In connection with such a transaction, the third parties may sell securities covered by and pursuant to this prospectus and an applicable prospectus supplement or pricing supplement, as the case may be. If so, the third party may use securities borrowed from us or others to settle such sales and may use securities received from us to close out or hedge any related short positions. We 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 or pricing supplement, as the case may be.

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 re-allowed 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 the selling security holders 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 or pricing supplement, as the case may be.

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. We 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 or pricing supplement, as the case may be.

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 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

-17-

Table of Contents

are purchased, unless otherwise specified in connection with any particular offering of securities. Any initial offering price and any discounts or concessions allowed, re-allowed or paid to dealers may be changed from time to time.

Securities may be sold directly by us or through agents designated by us 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 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.

Dealers

We may sell the offered securities to dealers as principals. We 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 at the time of resale. Dealers engaged by us may allow other dealers to participate in resales.

Direct Sales

We 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.

Indemnification; Other Relationships

We may agree to indemnify underwriters, dealers and agents against certain civil liabilities, including liabilities under the Securities Act and to make contributions 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 our 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 our common stock, which is listed on the NYSE American. We expect any shares of common stock will be listed on the NYSE American, but any other securities may or may not be listed on a national securities exchange. Any underwriters to whom securities are sold for public offering and sale may make a market in the securities, but such underwriters will not be obligated to do so and may discontinue any market making at any time without notice. The securities, other than the common stock, may or may not be listed on a national securities exchange.

To facilitate the offering of the securities, certain persons participating in the offering may engage in transactions that stabilize, maintain or otherwise affect the price of the securities. This may include over-allotments or short sales of the securities, which involves the sale by persons participating in the offering of more securities than we sold to them. In these circumstances, these persons would cover the over-allotments or short positions by making purchases in the open market or by exercising their over-allotment option. The effect of these transactions may be to stabilize or maintain the market price of the securities at

-18-

Table of Contents

a level above that which might otherwise prevail in the open market. These transactions may be discontinued at any time.

Dividends, distributions and stock splits.

Holders of common stock are entitled to receive dividends if, as and when such dividends are declared by the Board out of assets legally available therefor after payment of dividends required to be paid on shares of preferred stock, if any. Our existing debt arrangements restrict our ability to pay cash dividends.

Liquidation.

In the event of any dissolution, liquidation, or winding up of our affairs, whether voluntary or involuntary, after payment of debts and other liabilities and making provision for any holders of our preferred stock who have a liquidation preference, our remaining assets will be distributed ratably among the holders of common stock.

Table of Contents

Preferred Stock

Our Board has the authority to issue up to 1,000,000 shares of preferred stock in one or more series and to fix the rights, preferences, privileges and restrictions thereof, including dividend rights, dividend rates, conversion rates, voting rights, terms of redemption, redemption prices, liquidation preferences and the number of shares constituting any series or the designation of that series, which may be superior to those of the common stock, without further vote or action by the stockholders. One of the effects of undesignated preferred stock may be to enable our Board to render more difficult or to discourage an attempt to obtain control of us by means of a tender offer, proxy contest, merger or otherwise, and as a result to protect the continuity of our management. The issuance of shares of the preferred stock by the Board as described above may adversely affect the rights of the holders of common stock. For example, preferred stock issued by us may rank superior to the common stock as to dividend rights, liquidation preference or both, may have full or limited voting rights and may be convertible into shares of common stock. Accordingly, the issuance of shares of preferred stock may discourage bids for our common stock or may otherwise adversely affect the market price of our common stock.

If we offer shares of preferred stock directly or we offer shares of preferred stock indirectly through the offer of securities that are convertible, redeemable, exchangeable or exercisable into shares of preferred stock, the applicable prospectus supplement will describe the terms, including the following if applicable:

●

the designation of the series;

●

the number of shares of the series;

●

whether dividends, if any, will be cumulative or non-cumulative and the dividend rate of the series;

●

the dates at which dividends, if any, will be payable;

●

the redemption rights and price or prices, if any, for shares of the series;

●

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

●

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;

●

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;

●

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

●

the voting rights, if any, of the holders of the series.

Redeemable Convertible Preferred Stock

Voting Rights.

Holders of shares of the Redeemable Convertible Preferred Stock generally have no voting rights with respect to the shares of Redeemable Convertible Preferred Stock except as required by the DGCL, other applicable law, and the applicable certificate of designation.

Dividends.

Holders of Redeemable Convertible Preferred Stock are entitled to receive cumulative dividends at a fixed rate of 14.5% per annum on the “Liquidation Preference” (as defined in the applicable certificate of

-21-

designation, or $1,000 per share, as adjusted for any accrued and unpaid dividends added to the liquidation preference), compounding and accruing quarterly in arrears. Dividends may be paid in cash or, if not declared and paid in cash, the amount of any such dividend shall automatically accrue at a fixed rate of 16.0% per annum on the Liquidation Preference and be added to the Liquidation Preference (a “PIK Accrual”). Currently, the Company’s 2024 Amended Term Loan Agreement prohibits the payment of cash dividends. Additionally, while the Company has not declared or paid dividends on its common stock since its inception, holders of Redeemable Convertible Preferred Stock will be entitled to participate in any dividends or permitted distributions to holders of common stock on an as-converted basis should they occur.

Conversion Features.

In addition to the conversion rights noted in “Redemption Features (Change of Control)” below, holders of Redeemable Convertible Preferred Stock may convert their shares, from time to time and subject to certain limitations, into common stock at the Conversion Ratio equal to the then applicable Liquidation Preference at the time of conversion divided by the then applicable Conversion Price (initially set to reflect an 18% premium to the volume weighted average price of common stock for the 20 trading days immediately preceding the closing date); provided that issuances of shares of Common Stock upon conversion of the Redeemable Convertible Preferred Stock are subject to certain limitations imposed by NYSE American rules, which may limit the total number of shares of Common Stock issuable upon conversion of the Redeemable Convertible Preferred Stock absent stockholder approval. Additionally, in accordance with the applicable certificate of designation, and with respect to certain series of the Redeemable Convertible Preferred Stock, the Company may have the right, at its option, to effect a conversion of some or all outstanding shares into Common Stock at the then-applicable conversion ratio if specified valuation metrics are satisfied.

Redemption Features (Issuer).

Subject to the terms of the applicable certificate of designations and applicable restrictions (including stock exchange rules), the Company has the option to redeem the Redeemable Convertible Preferred Stock for cash at redemption prices that vary based on the time elapsed since issuance and may range from 100% to 120% of the then-applicable Liquidation Preference, as adjusted for accrued and unpaid dividends.

Redemption Features (Change of Control).

Upon the occurrence of a change of control, the rights of holders of the Redeemable Convertible Preferred Stock depend on the applicable series and the timing of the change of control relative to the applicable issuance date and any applicable “Term Loan Restricted Period” (as defined in the applicable certificate of designation). Depending on those factors, the Company may be permitted or required to offer holders a cash payment per share equal to the Liquidation Preference or the Redemption Price, as applicable and as defined under the relevant series, and, in certain circumstances, holders may have the right, in lieu of receiving cash, to elect to receive the same form and amount of consideration they would have received in the change of control transaction if their shares had been converted into Common Stock at the applicable Conversion Ratio, in each case subject to the notice and election mechanics set forth in the applicable certificate of designation.

Delaware Anti-Takeover Law and Certain Charter and Bylaw Provisions

Our Certificate of Incorporation, bylaws and the DGCL contain certain provisions that could discourage potential takeover attempts and make it more difficult for stockholders to change management or receive a premium for their shares.

Delaware law.

Under Section 203 of the DGCL, a corporation is prohibited from engaging in any business combination with a stockholder who, together with its affiliates or associates, owns (or who is an affiliate or associate of

-22-

Table of Contents

the corporation and within a three-year period did own) 15% or more of the corporation’s outstanding voting stock (which we refer to as an “interested stockholder”) for a three-year period following the time the stockholder became an interested stockholder, unless:

prior to the time the stockholder became an interested stockholder, the board of directors of the corporation approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder;

the interested stockholder owned at least 85% of the voting stock of the corporation, excluding specified shares, upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder; or

at or subsequent to the time the stockholder became an interested stockholder, the business combination is approved by the board of directors of the corporation and authorized by the affirmative vote, at an annual or special meeting, and not by written consent, of at least 66⅔% of the outstanding voting shares of the corporation, excluding shares held by that interested stockholder.

A business combination generally includes:

●

mergers and consolidations with or caused by an interested stockholder;

●

sales or other dispositions of 10% or more of the assets of a corporation to an interested stockholder;

●

specified transactions resulting in the issuance or transfer to an interested stockholder of any capital stock of the corporation or its subsidiaries; and

●

other transactions resulting in a disproportionate financial benefit to an interested stockholder.

The provisions of Section 203 of the DGCL do not apply to a corporation if, subject to certain requirements, the certificate of incorporation or bylaws of the corporation contain a provision expressly electing not to be governed by the provisions of the statute or the corporation does not have voting stock listed on a national securities exchange or held of record by more than 2,000 stockholders. Because our Certificate of Incorporation and bylaws do not include any provision to “opt-out” of Section 203 of the DGCL, the statute will apply to business combinations involving us.

Charter and bylaw provisions.

Delaware law permits any Delaware corporation to classify its board of directors into as many as three (3) classes with staggered terms of office. After initial implementation of a classified board, pursuant to the provision of our Certificate of Incorporation, our Board was declassified, effective as of the annual meeting of our stockholders, held on June 8, 2021. Our Certificate of Incorporation, which was duly adopted pursuant to the Joint Prepackaged Chapter 11 Plan of Halcón Resources Corporation and its Affiliated Debtors, dated as of August 2, 2019 (as amended, the “Plan”) and confirmed by the United States Bankruptcy Court for the District of Delaware entered September 24, 2019 and thereby approved pursuant to Section 303 of the DGCL, effective as of October 8, 2019 (the “Plan Effective Date”), and our amended and restated bylaws, as amended, provide that our Board shall not have less than one nor more than seven directors. Each nominee for director stands for election to a one-year term expiring at the next annual meeting of stockholders. None of our current directors served on our Board pre-emergence from bankruptcy.

Exclusive Forum.

Our Certificate of Incorporation provides that, unless the Company consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware shall be the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of the Company; (ii) any action asserting a

-23-

Table of Contents

claim of breach of a fiduciary duty owed by any director, officer or stockholder of the Company to the Company or the Company stockholders; (iii) any action asserting a claim arising pursuant to any provision of the DGCL; or (iv) any action asserting a claim governed by the internal affairs doctrine, in each case subject to said Court of Chancery having personal jurisdiction over the indispensable parties named as defendants therein.

The choice of forum provisions summarized above are not intended to, and would not, apply to suits brought to enforce any liability or duty created by the Securities Act or the Exchange Act or other claim for which the federal courts have exclusive jurisdiction. To the extent that any such claims may be based upon federal law claims, Section 27 of the Exchange Act creates exclusive federal jurisdiction over all suits brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder. Furthermore, Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder. Stockholders may be subject to increased costs to bring these claims, and the choice of forum provisions could have the effect of discouraging claims or limiting investors’ ability to bring claims in a judicial forum that they find favorable.

The transfer agent and registrar for our common stock is Broadridge Corporate Issuer Solutions, 1717 Arch Street, Suite 1300, Philadelphia, PA 19103. Its phone number is (877) 830-4936.

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 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.

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 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 (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.

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 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.

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 of, 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

●

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;

●

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

●

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

●

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

●

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

●

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

●

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 as unit agent for more than one series of units. A unit agent will have no duty or responsibility in

-29-

Table of Contents

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.

Legal Matters

The validity of the securities and certain other matters will be passed upon for us by Mayer Brown LLP. 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

Article Seventh of our Certificate of Incorporation provides for indemnification of our officers and directors, as well as our employees and agents, to the extent authorized by the Delaware General Corporation Law (the “DGCL”). Pursuant to Section 145 of the DGCL, we generally have the power to indemnify our current and former directors, officers, employees and agents against expenses and liabilities that they incur in connection with any suit to which they are, or are threatened to be made, a party by reason of their serving in such positions so long as they acted in good faith and in a manner they reasonably believed to be in, or not opposed to, our best interests, and with respect to any criminal action, they had no reasonable cause to believe their conduct was unlawful. The statute expressly provides that the power to indemnify or advance expenses authorized thereby is not exclusive of any rights granted under any charter provision, bylaw, agreement, vote of stockholders or disinterested directors, or otherwise, both as to actions in such person’s official capacity and as to action in another capacity while holding such office.

We also have the power to purchase and maintain insurance for such directors and officers. Section 145 of the DGCL authorizes a corporation to 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 or enterprise, against any liability asserted against him and incurred by him in any such capacity, or arising out of his status as such, whether or not the corporation would otherwise have the power to indemnify him.

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 theretofore 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 a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement;

(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.

(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.

(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;

(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.
