CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This prospectus contains forward-looking statements regarding future events and future results that are subject to the safe harbors created under the Securities Act of 1933, as amended (the "Securities Act") and the Exchange Act. All statements other than statements of historical facts included in this prospectus regarding Vitesse's financial position, operating and financial performance, development pace and drilling inventory and duration, capital expenditure requirements, business strategy and ability to scale, dividend plans and practices, Vitesse's stock repurchase program, plans and objectives of management for future operations, and industry conditions are forward-looking statements. When used in this release, 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 and sales, market size, collaborations, 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 Vitesse's control) that could cause actual results to differ materially from those set forth in the forward-looking statements, including the following: changes in oil and natural gas prices; the pace of drilling and completions activity on Vitesse's properties; Vitesse's ability to acquire additional development opportunities; potential acquisition transactions; integration and benefits of acquisitions, including the Powder River Acquisition, or the effects of such acquisitions on Vitesse's cash position and levels of indebtedness; changes in Vitesse's reserves estimates or the value thereof; disruptions to Vitesse's business due to acquisitions and other significant transactions; infrastructure constraints and related factors affecting Vitesse's properties; cost inflation or supply chain disruption; ongoing legal disputes over the Dakota Access Pipeline; the impact of general economic or industry conditions, nationally and/or in the communities in which Vitesse conducts business; changes in the interest rate environment, legislation or regulatory requirements; changes in U.S. trade policy, including the imposition of and changes in tariffs and resulting consequences; conditions of the securities markets; Vitesse's ability to raise or access capital; cyber-related risks; changes in accounting principles, policies or guidelines; and financial or political instability, health-related epidemics, acts of war (including the conflict in Ukraine, hostilities in the Middle East and the situation in Venezuela) or terrorism, and other economic, competitive, governmental, regulatory and technical factors affecting Vitesse's operations, products and prices. Additional information concerning potential factors that could affect future results is included in the section entitled "Part I, Item 1A. Risk Factors" and other sections of Vitesse's Annual Report on Form 10-K, subsequent Quarterly Reports on Form 10-Q and Current Reports on Form 8-K, as updated from time to time in amendments and subsequent reports filed with the SEC, which describe factors that could cause Vitesse's actual results to differ from those set forth in the forward-looking statements. Vitesse has based these forward-looking statements on its current expectations and assumptions about future events. While 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 Vitesse's control. Vitesse does not undertake any duty to update or revise any forward-looking statements, except as may be required by the federal securities laws.

THE COMPANY

We are an independent energy company focused on returning capital to stockholders through owning interests, predominantly as a non-operator, in oil and natural gas wells. We primarily engage in the acquisition, development and production of non-operated oil and natural gas properties in the United States that are generally operated by leading oil companies and are primarily in the Williston Basin of North Dakota and Montana, and we have limited operations in the Williston Basin through the strategic business combination transaction whereby we acquired all of the issued and outstanding common shares of Lucero Energy Corp., which we closed on March 7, 2025 in an all-stock transaction. We also have non-operated properties in the Central Rockies, including the Denver-Julesburg Basin and the Powder River Basin. Since our inception, we have built a strong and diversified asset base through a combination of property acquisitions, development activities and the implementation of proprietary platforms and processes utilizing our extensive data resources. We believe the location and concentration of our assets in some of North America's leading unconventional oil and natural gas resource plays, along with our technical and data capabilities, provide us with acquisition and development opportunities that will result in significant long-term value.

We are focused on using our cash flow to provide returns of capital to stockholders and maintain or grow our oil and natural gas production by developing our extensive inventory of drilling and completion locations and acquiring both producing wells and new development opportunities, while maintaining a strong balance sheet.

Vitesse has historically created value by acquiring non-operated minority working and mineral interests in oil and natural gas properties, comprising producing wells, near-term development opportunities and undeveloped acreage, and partnering with premier operators with significant experience in developing and producing oil and natural gas in our core areas. Over the past twelve years, we have executed on our technical, data driven, and financially disciplined acquisition and development strategy to build our core position in the Williston Basin and Central Rockies and grow our oil and natural gas production. During that time, we have focused on limiting our downside by maintaining conservative acquisition guidelines, limiting our debt leverage and opportunistically hedging our production. As a result, we have been able to preserve value when many independent energy companies were forced into financial recapitalizations and restructurings when commodity prices collapsed in 2014, 2018 and 2020.

Our principal executive offices are located at 5619 DTC Parkway, Suite 700, Greenwood Village, Colorado 80111, and our telephone number is 720-361-2500.

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 any 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" and "Cautionary Statement Regarding Forward-Looking Statements" in this prospectus.

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.

Generally, to be timely, a stockholder's notice must be received at our principal executive offices not less than 120 days, nor earlier than 150 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 received no more than 190 days prior to such annual meeting nor less than the later of (i) 160 days prior to such annual meeting and (ii) ten days after 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(a)(3) of the Exchange Act not later than five business 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 such update and supplement must be delivered to the corporate secretary not later than ten business days after the record date for the annual meeting of stockholders.

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.

Special Meetings of Stockholders

Our Bylaws provide that a special meeting of stockholders may be called only by the chairperson, the chief executive officer or the affirmative vote of the majority of our Board.

Anti-Takeover Provision of the Delaware General Corporation Law

As a Delaware corporation, we are subject to Section 203 of the DGCL. Section 203 of the DGCL prohibits a Delaware corporation from engaging in a business combination with any interested stockholder for a period of three years following the date the person became an interested stockholder, unless (i) prior to such time the board of directors approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder; (ii) upon consummation of 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 outstanding at the time the transaction commenced; or (iii) at or subsequent to such time the business combination is approved by the board of directors and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least

66 2∕3% of the outstanding voting stock which is not owned by the interested stockholder. In general, Section 203 of the DGCL defines an "interested stockholder" as an entity or person who, together with the entity's or person's affiliates, beneficially owns, or is an affiliate of the corporation and within three years prior to the time of determination of interested stockholder status did own, 15% or more of the outstanding voting stock of the corporation.

Transfer Agent and Registrar

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

Registration Rights

On April 8, 2026, we completed the Powder River Acquisition, pursuant to which we issued 1,935,698 shares of common stock to Titan as consideration. In connection with the Powder River Acquisition, we entered into the Registration Rights Agreement, whereby we, among other things, agreed to file with the SEC a shelf registration statement registering for resale the shares of common stock issued to Titan as consideration in connection with the closing of the Powder River Acquisition and to use our commercially reasonable efforts to maintain an effective resale shelf registration statement and granted piggyback registration rights in certain circumstances.

This registration statement is being filed pursuant to our obligations under the Registration Rights Agreement. In accordance with the terms of the Registration Rights Agreement, we have agreed to pay all fees and expenses with respect to the filing hereof, and the reasonable fees and disbursements of one special legal counsel to represent all selling stockholders in an underwritten offering not to exceed $100,000 per underwritten offering, excluding certain expenses.

SELLING STOCKHOLDER

This prospectus covers the offering for resale, from time to time, in one or more offerings, of up to 1,935,698 shares of common stock by the selling stockholder identified below. We issued these shares to the selling stockholder at closing of and as consideration for the Powder River Acquisition. The issuance of shares to the selling stockholder was exempt from the registration requirements of the Securities Act under Section 4(a)(2) of the Securities Act. We are registering for resale such shares in accordance with the Registration Rights Agreement. We have no other relationship with the selling stockholder other than in connection with the Powder River Acquisition and the Registration Rights Agreement.

The percent of beneficial ownership for the selling stockholder is based on 41,712,424 shares of common stock outstanding as of April 8, 2026. Beneficial ownership is determined in accordance with the rules of the SEC. These rules generally attribute beneficial ownership of securities to persons who possess sole or shared voting or dispositive power with respect to such securities. Except as otherwise indicated, the selling stockholder listed below has sole voting and dispositive power with respect to the shares of common stock beneficially owned by them.

The following table sets forth the number of shares of common stock being offered by the selling stockholder, including its donees, pledgees, transferees or other successors-in-interest. The following table also sets forth the number of shares of common stock known to us, based upon written representations by the selling stockholder, to be beneficially owned by the selling stockholder as of the date of this prospectus. The selling stockholder is not making any representation that any shares of common stock covered by this prospectus will be offered for sale. The selling stockholder may sell all, some or none of the shares of common stock covered by this prospectus and reserves the right to accept or reject, in whole or in part, any proposed sale of the shares of common stock. Please read "Plan of Distribution" for additional information.

The selling stockholder also may resell all or a portion of the securities in open market transactions in reliance upon Rule 144 under the Securities Act, provided that it meets the criteria and conforms to the requirements of that rule. In connection with an underwritten offering, underwriters or agents may receive compensation in the form of discounts, concessions or commissions from the selling stockholder or from purchasers of the offered securities for whom they may act as agents. In addition, underwriters may sell the securities to or through dealers, and those dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or

commissions from the purchasers for whom they may act as agents. The selling stockholder and any underwriters, dealers or agents participating in a distribution of the securities may be deemed to be "underwriters" within the meaning of the Securities Act, and any profit on the sale of the securities by the selling stockholder and any commissions received by broker-dealers may be deemed to be underwriting commissions under the Securities Act.

The selling stockholder may agree to indemnify an underwriter, broker-dealer or agent against certain liabilities related to the sale of the securities, including liabilities under the Securities Act. The selling stockholder has advised us that it has not entered into any agreements, understandings or arrangements with any underwriters or broker-dealers regarding the sale of its securities. Upon our notification by the selling stockholder that any material arrangement has been entered into with an underwriter or broker-dealer for the sale of securities through a block trade, special offering, exchange distribution, secondary distribution or a purchase by an underwriter or broker-dealer, we will file a supplement to this prospectus, if required, pursuant to Rule 424(b) under the Securities Act, disclosing certain material information, including:

•

the name of the selling stockholder (if other than as disclosed herein);

​

•

the number of securities being offered;

​

•

the terms of the offering;

​

•

the names of the participating underwriters, broker-dealers or agents;

​

•

any discounts, commissions or other compensation paid to underwriters or broker-dealers and any discounts, commissions or concessions allowed or reallowed or paid by any underwriters to dealers;

​

•

the public offering price; and

​

•

other material terms of the offering.

​

In addition, upon being notified by the selling stockholder that a donee, pledgee, transferee or other successor-in-interest intends to sell its securities, we will, to the extent required, promptly file a supplement to this prospectus to name specifically such person as selling a stockholder.

The selling stockholder is subject to the applicable provisions of the Exchange Act and the rules and regulations under the Exchange Act, including Regulation M. This regulation may limit the timing of purchases and sales of securities offered in this prospectus by the selling stockholder. The anti-manipulation rules under the Exchange Act may apply to sales of securities in the market and to the activities of the selling stockholder and its 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.

To the extent required, this prospectus may be amended and/or supplemented from time to time to describe a specific plan of distribution. Instead of selling the securities under this prospectus, the selling stockholder may sell the securities in compliance with the provisions of Rule 144 under the Securities Act, if available, or pursuant to other available exemptions from the registration requirements of the Securities Act.

LEGAL MATTERS

The validity of the securities and certain other matters will be passed upon for us by Vinson & Elkins L.L.P., New York, New York. 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, and Bylaws (and in accordance with Section 145 of 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 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 SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable.

Reference is made to the form 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:

​

(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:

​

(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

​

(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 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.

​

(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.

​
