    CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

     

    This prospectus, any prospectus supplement delivered with this prospectus and the documents we incorporate by reference may contain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). All statements, other than statements of historical fact, included or incorporated by reference in this prospectus or any prospectus supplement hereto are forward-looking statements, including, but not limited to, statements regarding our strategy, prospects, plans, objectives, future operations, future revenue and earnings, projected margins and expenses, markets for our services, potential acquisitions or strategic alliances, financial position, and liquidity and anticipated cash needs and availability. The words “anticipates,” “believes,” “targets,” “should,” “contemplates,” “estimates,” “expects,” “intends,” “may,” “plans,” “projects,” “will,” “would,” “potential,” “remains,” “continues,” “likely,” or variations of such words and similar expressions or the negatives thereof are intended to identify forward-looking statements. However, not all forward-looking statements contain these identifying words. These forward-looking statements represent our management’s expectations as of the date of the respective filing and involve known and unknown risks, uncertainties and other factors that may cause our actual results, performance and achievements or industry results to be materially different from any future results, performance or achievements expressed or implied by such forward-looking statements.

     

    We cannot guarantee the accuracy of the forward-looking statements, and you should be aware that results and events could differ materially and adversely from those contained in the forward-looking statements due to a number of risks and uncertainties including, but not limited to, the following:

     

    ●our status as an early stage company with a history of losses and our expectation of incurring significant expenses and continuing losses for the foreseeable future;

     

    ●our ability to develop key commercial relationships with supplies and customers;

     

    ●the expected performance of the KARNO generator and system;

     

    ●the execution of the strategic shift from our powertrain business to our KARNO business;

     

    ●our ability to comply with governmental regulations related to defense spending and procurement;

     

    ●the suitability of our products for defense applications;

     

    ●analyses and other information based on expectations of future performance;

     

    ●inability to generate sufficient cash flow from operations or to obtain adequate financing to fund capital expenditures, meet our working capital requirements or fund planned investments;

     

    ●global economic, political and social conditions and financial markets;

     

    ●our ability to recruit and/or retain key members of our senior management, including Thomas Healy, and key technical employees;

     

    ●cyber-attacks and other security breaches of our information and technology systems;

     

    ●and the other risks and uncertainties described under the heading “Risk Factors” in our other SEC filings including any prospectus supplement delivered with this prospectus and in our Annual Report on Form 10-K (See Item 1A. Risk Factors), as supplemented by our Quarterly Reports on Form 10-Q. 

     

    Should one or more of these risks or uncertainties materialize, or should any of our assumptions prove incorrect, actual results and outcomes may differ materially from the results and outcomes discussed in or anticipated by the forward-looking statements. Readers are urged not to place undue reliance on forward-looking statements, which speak only as of the date of this prospectus or as of the date of any prospectus supplement or the documents we incorporate by reference. We undertake no obligation to update or revise any forward-looking statement, whether as a result of new information, future events, or otherwise, except as may be required under applicable securities laws. Readers are urged to carefully review and consider the various disclosures made throughout the entirety of this prospectus, any prospectus supplement delivered with this prospectus and the documents we incorporate by reference.

    SUMMARY

     

    The following is only a summary. Because it is a summary, it may not contain all of the information that may be important to you. Investing in our securities involves risks. We urge you to read the entire prospectus, including information set forth under the heading “Risk Factors” and our financial statements and other information included herein or incorporated by reference from our other filings with the SEC.

     

    The Company

     

    We are committed to creating innovative solutions that enable clean, efficient, and flexible electricity production while contributing positively to the environment in the energy economy. Our primary product offering, the KARNOTM Power Module, is a modular, fully enclosed, fuel-agnostic and fully integrated power generating solution. The KARNO Power Module is powered by KARNO Core, a heat powered linear generator, to produce electricity with significant improvements in efficiency, emissions and lifecycle cost compared to conventional generation technologies. Our KARNO Power Modules enable effective power generation using a wide range of fuel sources, including conventional fuels such as natural gas, propane or diesel, waste fuels such as landfill gas, wellhead gas, and zero carbon fuels such as renewable hydrogen and ammonia. We are initially targeting the datacenter, commercial, industrial, and defense sectors with a locally-deployable generator designed to meet a wide range of power generation needs. We plan to scale up our KARNO Power Module solution to address larger utility-scale power needs and to develop future variants for industrial waste heat, nuclear, household use and e-mobility applications such as vehicles and marine vessels. Additionally, the KARNO Power Module technology is well-suited to provide combined heat and power in various stationary applications.

    RISK FACTORS

     

    Investment in any securities offered pursuant to this prospectus and any applicable prospectus supplement involves risks. You should carefully consider the risk factors incorporated by reference to our most recent Annual Report on Form 10-K and any subsequently filed Quarterly Reports on Form 10-Q or Current Reports on Form 8-K, and all other information contained in or incorporated by reference into this prospectus, as updated by our subsequent filings under the Exchange Act, and the risk factors and other information contained in any applicable prospectus supplement and any applicable free writing prospectus before acquiring any of such securities. Any of these risks and uncertainties could have a material adverse effect on our business, growth plans, operating or capital costs, financial condition, results of operations and our ability to meet our capital expenditure plans, other obligations and financial commitments. Additional risks and uncertainties not presently known to us or that we currently believe to be immaterial may become material and adversely affect our business. The occurrence of any of these risks might cause you to lose all or part of your investment in the offered securities.

    USE OF PROCEEDS

     

    Except as otherwise provided in an applicable prospectus supplement, we will use the net proceeds we receive from the sale of the securities covered by this prospectus for general corporate purposes, which may include, among other things, capital expenditures. More detailed information regarding the use of proceeds from a sale of securities will be included in the applicable prospectus supplement.

    DESCRIPTION OF COMMON AND PREFERRED STOCK

     

    Authorized and Outstanding Stock

     

    Our Second Amended and Restated Certificate of Incorporation (the “Certificate of Incorporation”) authorizes the issuance of 250,000,000 shares of Common Stock, $0.0001 par value per share, and 10,000,000 shares of preferred stock, $0.0001 par value per share. As of February 19, 2026, there were 177,812,784 shares of Common Stock and no shares of preferred stock outstanding. The outstanding shares of Common Stock are duly authorized, validly issued, fully paid and non-assessable.

     

    The following description of the capital stock of Hyliion is based upon the Certificate of Incorporation of the Company, the Amended and Restated Bylaws of the Company (the “Bylaws”) and applicable provisions of law. We have summarized certain portions of the Certificate of Incorporation and the Bylaws below. The summary is not complete and is subject to, and is qualified in its entirety by express reference to, the provisions of applicable law and to the Certificate of Incorporation and Bylaws.

     

    Common Stock

     

    Voting Power

     

    Except as otherwise required by law or as otherwise provided in any certificate of designation for any series of preferred stock, the holders of Common Stock will possess all voting power for the election of our directors and all other matters requiring stockholder action. Holders of Common Stock will be entitled to one vote per share on matters to be voted on by stockholders.

     

    Dividends

     

    Holders of Common Stock will be entitled dividends, if any, as may be declared from time to time by the board of directors of the Company (the “Board”) in its discretion. Such dividends may be paid in cash, in property or in shares of the capital stock, subject to the provisions of our Certificate of Incorporation and applicable law. We may retain future earnings, if any, for future operations, expansion and debt repayment and have no current plans to pay cash dividends for the foreseeable future. Any decision to declare and pay dividends in the future will be made at the discretion of the Board and will depend on, among other things, our results of operations, financial condition, cash requirements, contractual restrictions and other factors that the Board may deem relevant. In addition, our ability to pay dividends may be limited by covenants of any existing and future outstanding indebtedness we or our subsidiaries incur.

     

    Preemptive or Other Rights

     

    Holders of Common Stock have no conversion, preemptive or other subscription rights and there will be no sinking fund or redemption provisions applicable to the Common Stock.

     

    Election of Directors

     

    The Board is divided into three classes, each of which will serve for a term of three years with only one class of directors being elected in each year. All elections of directors are determined by a plurality of the votes cast, and there is no cumulative voting with respect to the election of directors..

     

    Preferred Stock

     

    Our Certificate of Incorporation provides that shares of preferred stock may be issued from time to time in one or more series. The Board is authorized to fix the voting rights, if any, designations, powers, preferences, the relative, participating, optional or other special rights and any qualifications, limitations and restrictions thereof, applicable to the shares of each series. The Board will be able to, without stockholder approval, issue preferred stock with voting and other rights that could adversely affect the voting power and other rights of the holders of the Common Stock and could have anti-takeover effects. The ability of the Board to issue preferred stock without stockholder approval could have the effect of delaying, deferring or preventing a change of control of Hyliion or the removal of the management.

     

    4

     

    Registration Rights

     

    The Amended and Restated Registration Rights Agreement, dated October 1, 2020, among Hyliion, Tortoise Sponsor LLC, a Delaware limited liability company, TortoiseEcofin Borrower LLC, a Delaware limited liability company and the holders (“Holders”) party thereto (the “A&R Registration Rights Agreement”) generally required us to file a registration statement registering the resale of certain of the Holders’ securities (collectively, the “Registrable Securities”) of our predecessor company, Tortoise Acquisition Corp. (“TortoiseCorp”), with the SEC as soon as practicable following consummation of the merger pursuant to the terms of the Business Combination Agreement, dated June 18, 2020, between TortoiseCorp and each of the shareholders of Hyliion Inc. (the “Business Combination”). We filed such registration statement, as amended, with the SEC on October 23, 2020 (File No. 333-249649).

     

    Certain of the Holders are granted demand underwritten offering registration rights and all of the Holders are granted piggyback registration rights. The A&R Registration Rights Agreement does not provide for the payment of any cash penalties by TortoiseCorp if it fails to satisfy any of its obligations under the A&R Registration Rights Agreement.

     

    At any time when we are required to file public reports with the SEC under the Exchange Act, the A&R Registration Rights Agreement requires us to timely comply with the reporting requirements. Upon a Holders’ reasonable request, we shall take such further action required from time to time to enable such Holder to sell shares of Registrable Securities held by such Holder without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 promulgated under the Securities Act (or any successor rule promulgated thereafter by the SEC).

     

    The A&R Registration Rights Agreement will terminate upon the earlier of (a) ten years following the closing of the Business Combination or (b) the date as of which the Holders cease to hold any Registrable Securities.

     

    Certain Anti-Takeover Provisions

     

    Special Meetings of Stockholders

     

    Our Certificate of Incorporation provides that special meetings of our stockholders may be called by such persons as provided in the Bylaws. The Bylaws provide that special meetings of our stockholders may be called only, for any purpose as is a proper matter for stockholder action under Delaware, by (i) our Chairperson of the Board, (ii) our Chief Executive Officer or the President if the Chairperson of the Board is unavailable, or (iii) the Board pursuant to a resolution adopted by a majority of the total number of authorized directors (whether or not there exist any vacancies in previously authorized directorships at the time any such resolution is presented to the Board for adoption).

     

    Advance Notice Requirements for Stockholder Proposals and Director Nominations

     

    Our Bylaws provide that stockholders seeking to bring business before our annual meeting of stockholders, or to nominate candidates for election as directors at our annual meeting of stockholders, must provide timely notice of their intent in writing. To be timely under the Bylaws, a stockholder’s notice will need to be received by the Company secretary at our principal executive offices not later than the close of business on the 90th day nor earlier than the open of business on the 120th day prior to the first anniversary of the preceding year’s annual meeting of stockholders; provided, however, that in the event that no annual meeting was held in the previous year or the annual meeting is called for a date that is more than 30 days before or after the anniversary date of the previous year’s annual meeting, notice by the stockholder must be received by the secretary no earlier than the close of business on the 120th day prior to such annual meeting and no later than the close of business on the latter of the 90th day prior to such annual meeting or the 10th day following the day on which public announcement of the date of such meeting is first made. Our Certificate of Incorporation and the Bylaws specify certain requirements as to the form and content of a stockholders’ meeting. These provisions may preclude our stockholders from bringing matters before our annual meeting of stockholders or from making nominations for directors at our annual meeting of stockholders.

     

    5

     

    Authorized but Unissued Shares

     

    Our authorized but unissued Common Stock and preferred stock are available for future issuances without stockholder approval and could be utilized for a variety of corporate purposes, including future offerings to raise additional capital, acquisitions and employee benefit plans. The existence of authorized but unissued and unreserved Common Stock and preferred stock could render more difficult or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger or otherwise.

     

    Exclusive Forum Selection

     

    Our Certificate of Incorporation requires, to the fullest extent permitted by law, that derivative actions brought in our name, actions against current or former directors, officers and employees for breach of fiduciary duty, other similar actions, any other action as to which the Delaware General Corporation Law (“DGCL”) confers jurisdiction to the Court of Chancery of the State of Delaware and any action or proceeding concerning the validity of our Certificate of Incorporation or the Bylaws may be brought only in the Court of Chancery in the State of Delaware (or, if and only if the Court of Chancery of the State of Delaware does not have subject matter jurisdiction thereof, any state court located in the State of Delaware or, if and only if all such state courts lack subject matter jurisdiction, the federal district court for the District of Delaware). Although we believe this provision benefits us by providing increased consistency in the application of Delaware law in the types of lawsuits to which it applies, the provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us and our directors, officers or other employees and may have the effect of discouraging lawsuits against our directors and officers. This provision would not apply to claims brought to enforce a duty or liability created by the Exchange Act or any 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. However, our Certificate of Incorporation provides that the federal district courts of the United States shall be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act. Stockholders may be subject to increased costs to bring these claims, and the exclusive forum provision could have the effect of discouraging claims or limiting investors’ ability to bring claims in a judicial forum that they find favorable. In addition, the enforceability of similar exclusive forum provisions in other companies’ certificates of incorporation has been challenged in legal proceedings, and it is possible that, in connection with one or more actions or proceedings described above, a court could rule that this provision in our Certificate of Incorporation is inapplicable or unenforceable.

     

    Section 203 of the Delaware General Corporation Law

     

    We do not opt out of Section 203 of the DGCL under our Certificate of Incorporation. Section 203 prohibits a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years after the date that such stockholder became an interested stockholder, subject to certain exceptions.

     

    Transfer Agent and Registrar

     

    The transfer agent and registrar for our Common Stock is Continental Stock Transfer & Trust Company.

     

    Listing of Securities

     

    Our Common Stock is listed on the NYSE American under the symbol “HYLN”.

    DESCRIPTION OF DEBT SECURITIES

     

    General

     

    We may issue debt securities in one or more series. When used in this “Description of Debt Securities” section, unless we state otherwise or the context clearly indicates otherwise, references to the “Company,” “we,” “us,” and “our” refer to Hyliion Holdings Corp. and not any of its subsidiaries. We may issue senior or subordinated debt securities. None of the debt securities will be secured by any of our property or assets. Thus, holders of our debt securities will be unsecured creditors.

     

    The debt indenture and its associated documents, including the debt security, will contain the full legal text of the matters described in this section and the applicable prospectus supplement. We have filed a form of the indenture with the SEC as an exhibit to our registration statement, of which this prospectus is a part. See “Where You Can Find More Information” in this prospectus for information on how to obtain copies of them.

     

    This section and the applicable prospectus supplement summarize material terms of the indenture and the related debt security. They do not, however, describe every aspect of the indenture and the related debt security. For example, in this section and the applicable prospectus supplement, we use terms that have been given special meaning in the indenture, but we do not describe the meaning of all the terms that may be important to holders. The applicable prospectus supplement will have a more detailed description of the specific terms of the applicable debt security.

     

    Indenture

     

    The debt securities will be governed by a document called an indenture. The indenture is a contract between us and the trustee named in the indenture.

     

    The trustee has two main roles:

     

    ●First, the trustee can enforce the holders’ rights against us if we default. There are some limitations on the extent to which the trustee acts on the holders’ behalf, which we describe later under “— Default, Remedies and Waiver of Default.”

     

    ●Second, the trustee performs administrative duties for us, such as sending interest payments and notices to holders.

     

    Series of Debt Securities

     

    We may issue as many distinct debt securities or series of debt securities under the indenture as we wish. This section summarizes terms of the securities that apply generally to all debt securities and series of debt securities. The provisions of the indenture allow us not only to issue debt securities with terms different from those of debt securities previously issued under the indenture, but also to “reopen” a previously issued series of debt securities and issue additional debt securities of that series. We will describe most of the financial and other specific terms of any debt security we issue in the applicable prospectus supplement. Those terms may vary from the terms described here.

     

    The specific terms of any debt security we issue as described in the applicable prospectus supplement will supplement and, if applicable, modify or replace the general terms described in this section. If there are any differences between the applicable prospectus supplement and this prospectus with respect to a debt security, the applicable prospectus supplement will control.

     

    When we refer to a “series of debt securities,” we mean a series of debt securities issued under the indenture. When we refer to “the applicable prospectus supplement,” we mean the prospectus supplement describing the specific terms of a particular debt security. The terms used in the applicable prospectus supplement will have the meanings described in this prospectus, unless otherwise specified.

     

    7

     

    Amounts of Issuances

     

    The indenture will not limit the aggregate amount of debt securities that we may issue or the number of series or the aggregate amount of any particular series. We may issue debt securities and other securities at any time without the holders’ consent and without notifying holders. The indenture and the debt securities will not limit our ability to incur other indebtedness or to issue other securities other than as specified in a particular debt security, as applicable. Also, unless otherwise specified below or in the applicable prospectus supplement, we are not subject to financial or similar restrictions by the terms of the debt securities.

     

    Principal Amount, Stated Maturity and Maturity

     

    Unless otherwise stated, the principal amount of a debt security means the principal amount payable at its stated maturity, unless that amount is not determinable, in which case the principal amount of a debt security is its face amount. The term “stated maturity” with respect to any debt security means the day on which the principal amount of the debt security is scheduled to become due. The principal may become due sooner, by reason of redemption, acceleration after a default or otherwise in accordance with the terms of the debt security. The day on which the principal actually becomes due, whether at the stated maturity or earlier, is called the “maturity” of the principal. We also use the terms “stated maturity” and “maturity” to refer to the days when other payments become due. For example, we may refer to a regular interest payment date when an installment of interest is scheduled to become due as the “stated maturity” of that installment. When we refer to the “stated maturity” or the “maturity” of a debt security without specifying a particular payment, we mean the stated maturity or maturity, as the case may be, of the principal.

     

    Specific Terms of Debt Securities

     

    The applicable prospectus supplement will describe the specific terms of the debt security, which will include some or all of the following:

     

    ●the title of the series of the debt security and whether it is a senior debt security or a subordinated debt security;

     

    ●any limit on the total principal amount of the debt securities of the same series;

     

    ●the stated maturity;

     

    ●the currency or currencies for payment of principal and interest, if not U.S. dollars;

     

    ●the price at which we originally issue the debt security, expressed as a percentage of the principal amount, and the original issue date;

     

    ●whether the debt security is a fixed-rate debt security, a floating rate debt security or an indexed debt security;

     

    ●if the debt security is a fixed-rate debt security, the yearly rate at which the holder’s debt security will bear interest, if any, and the interest payment dates;

     

    ●if the debt security is a floating-rate debt security, the interest rate basis; any applicable index currency or index maturity, spread or spread multiplier or initial base rate, maximum rate or minimum rate; the interest reset, determination, calculation and payment dates; the day count convention used to calculate interest payments for any period; the business day convention; and the calculation agent;

     

    ●if the debt security is an indexed debt security, the principal amount, if any, we will pay at maturity, interest payment dates, the amount of interest, if any, we will pay on an interest payment date or the formula we will use to calculate these amounts, if any, and the terms on which the debt security will be exchangeable for or payable in cash, securities or other property;

     

    ●if the debt security may be converted into or exercised or exchanged for common or preferred stock or other securities of the Company or debt or equity securities of one or more third parties, the terms on which conversion, exercise or exchange may occur, including whether conversion, exercise or exchange is mandatory, at the option of the holder or at our option, the period during which conversion, exercise or exchange may occur, the initial conversion, exercise or exchange price or rate and the circumstances or manner in which the amount of common or preferred stock or other securities issuable upon conversion, exercise or exchange may be adjusted;

     

    8

     

    ●if the debt security is also an original issue discount debt security, the yield to maturity;

     

    ●if applicable, the circumstances under which the debt security may be redeemed at our option or repaid at the holder’s option before the stated maturity, including any redemption commencement date, repayment date(s), redemption price(s) and redemption period(s);

     

    ●the authorized denominations, if other than $2,000 and multiples of $1,000;

     

    ●the depositary for the debt security, if other than The Depository Trust Company (“DTC”), and any circumstances under which the holder may request securities in non-global form, if we choose not to issue the debt security in book-entry form only;

     

    ●if applicable, the circumstances under which we will pay additional amounts on any debt securities held by a person who is not a United States person for tax purposes and under which we can redeem the debt securities if we have to pay additional amounts;

     

    ●any guarantors of the debt security;

     

    ●the names and duties of any co-trustees, depositaries, authenticating agents, paying agents, transfer agents or registrars for the debt security, as applicable; and

     

    ●any other terms of the debt security, which could be different from those described in this prospectus.

     

    Governing Law

     

    The indenture and the debt securities will be governed by New York law.

     

    Form of Debt Securities

     

    We will issue each debt security only in registered form, without coupons, unless we specify otherwise in the applicable prospectus supplement. In addition, we will issue each debt security in global — i.e., book-entry — form only, unless we specify otherwise in the applicable prospectus supplement. Debt securities in book-entry form will be represented by a global security registered in the name of a depositary, which will be the holder of all the debt securities represented by the global security. Those who own beneficial interests in a global debt security will do so through participants in the depositary’s securities clearance system, and the rights of these indirect owners will be governed solely by the applicable procedures of the depositary and its participants. References to “holders” in this section mean those who own debt securities registered in their own names, on the books that we or the trustee maintain for this purpose, and not those who own beneficial interests in debt securities registered in street name or in debt securities issued in book-entry form through one or more depositaries.

     

    Unless otherwise indicated in the prospectus supplement, the following is a summary of the depositary arrangements applicable to debt securities issued in global form and for which DTC acts as depositary. 

     

    Each global debt security will be deposited with, or on behalf of, DTC, as depositary, or its nominee, and registered in the name of a nominee of DTC. Except under the limited circumstances described below, global debt securities are not exchangeable for definitive certificated debt securities.

     

    Ownership of beneficial interests in a global debt security is limited to institutions that have accounts with DTC or its nominee, or persons that may hold interests through those participants. In addition, ownership of beneficial interests by participants in a global debt security will be evidenced only by, and the transfer of that ownership interest will be effected only through, records maintained by DTC or its nominee for a global debt security. Ownership of beneficial interests in a global debt security by persons that hold those interests through participants will be evidenced only by, and the transfer of that ownership interest within that participant will be effected only through, records maintained by that participant. DTC has no knowledge of the actual beneficial owners of the debt securities. Beneficial owners will not receive written confirmation from DTC of their purchase, but beneficial owners are expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the participants through which the beneficial owners entered the transaction. The laws of some jurisdictions require that certain purchasers of securities take physical delivery of securities they purchase in definitive form. These laws may impair the holders’ ability to transfer beneficial interests in a global debt security.

     

    9

     

    We will make payment of principal of, and interest on, debt securities represented by a global debt security registered in the name of or held by DTC or its nominee to DTC or its nominee, as the case may be, as the registered owner and holder of the global debt security representing those debt securities. DTC has advised us that upon receipt of any payment of principal of, or interest on, a global debt security, DTC immediately will credit accounts of participants on its book-entry registration and transfer system with payments in amounts proportionate to their respective interests in the principal amount of that global debt security, as shown in the records of DTC. Payments by participants to owners of beneficial interests in a global debt security held through those participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in “street name,” and will be the sole responsibility of those participants, subject to any statutory or regulatory requirements that may be in effect from time to time.

     

    Neither we, any trustee nor any of our respective agents will be responsible for any aspect of the records of DTC, any nominee or any participant relating to, or payments made on account of, beneficial interests in a permanent global debt security or for maintaining, supervising or reviewing any of the records of DTC, any nominee or any participant relating to such beneficial interests.

     

    A global debt security is exchangeable for definitive certificated debt securities registered in the name of, and a transfer of a global debt security may be registered to, any person other than DTC or its nominee, only if:

     

    ●DTC notifies us that it is unwilling, unable or no longer qualified to continue as depositary for that global security or has ceased to be a registered clearing agency and we do not appoint another institution to act as depositary within 60 days; or

     

    ●we notify the trustee that we wish to terminate that global security.

     

    Any global debt security that is exchangeable pursuant to the preceding paragraph will be exchangeable in whole for definitive certificated debt securities in registered form, of like tenor and of an equal aggregate principal amount as the global debt security, in denominations specified in the applicable prospectus supplement, if other than $2,000 and multiples of $1,000. The definitive debt securities will be registered by the registrar in the name or names instructed by DTC. We expect that these instructions may be based upon directions received by DTC from its participants with respect to ownership of beneficial interests in the global debt security.

     

    Except as provided above or in the applicable prospectus supplement, owners of the beneficial interests in a global debt security will not be entitled to receive physical delivery of debt securities in definitive certificated form and will not be considered the holders of debt securities for any purpose under the indenture. Except as provided above, no global debt security shall be exchangeable except for another global debt security of like denomination and tenor to be registered in the name of DTC or its nominee. Accordingly, each person owning a beneficial interest in a global debt security must rely on the procedures of DTC and, if that person is not a participant, on the procedures of the participant through which that person owns its interest, to exercise any rights of a holder under the global debt security or the indenture.

     

    We understand that, under existing industry practices, in the event that we request any action of holders, or an owner of a beneficial interest in a global debt security desires to give or take any action that a holder is entitled to give or take under the debt securities or the indenture, DTC would authorize the participants holding the relevant beneficial interests to give or take that action. Additionally, those participants would authorize beneficial owners owning through those participants to give or take that action or would otherwise act upon the instructions of beneficial owners owning through them.

     

    DTC has advised us that it is a limited-purpose trust company organized under the laws of the State of New York, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code, and a “clearing agency” registered under the Exchange Act. DTC was created to hold securities of its participants and to facilitate the clearance and settlement of transactions among its participants in securities through electronic book-entry changes in accounts of the participants. By doing so, DTC eliminates the need for physical movement of securities certificates.

     

    10

     

    DTC’s participants include securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations. DTC is a wholly owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”); DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies; and DTCC is owned by the users of its regulated subsidiaries. Access to DTC’s book-entry system is also available to others, such as banks, brokers, dealers, and trust companies that clear through or maintain a custodial relationship with a participant, either directly or indirectly. The rules applicable to DTC and its participants are on file with the SEC.

     

    Investors may hold interests in the debt securities outside the U.S. through the Euroclear System (“Euroclear”) or Clearstream Banking (“Clearstream”) if they are participants in those systems, or indirectly through organizations which are participants in those systems. Euroclear and Clearstream will hold interests on behalf of their participants through customers’ securities accounts in Euroclear’s and Clearstream’s names on the books of their respective depositaries, which in turn will hold such interests in customers’ securities accounts in the depositaries’ names on the books of DTC. All securities in Euroclear or Clearstream are held on a fungible basis without attribution of specific certificates to specific securities clearance accounts.

     

    The following is based on information furnished by Euroclear or Clearstream, as the case may be. Euroclear has advised us that:

     

    ●It was created in 1968 to hold securities for participants of Euroclear and to clear and settle transactions between Euroclear participants through simultaneous electronic book-entry delivery against payment, thereby eliminating the need for physical movement of certificates and any risk from lack of simultaneous transfers of securities and cash;

     

    ●Euroclear includes various other services, including securities lending and borrowing and interfaces with domestic markets in several countries;

     

    ●Euroclear is operated by Euroclear Bank SA/NV, as operator of the Euroclear System (the “Euroclear Operator”), under contract with Euroclear Clearance Systems S.C., a Belgian cooperative corporation (the “Cooperative”);

     

    ●The Euroclear Operator conducts all operations, and all Euroclear securities clearance accounts and Euroclear cash accounts are accounts with the Euroclear Operator, not the Cooperative. The Cooperative establishes policy for Euroclear on behalf of Euroclear participants. Euroclear participants include banks (including central banks), securities brokers and dealers and other professional financial intermediaries and may include underwriters of debt securities offered by this prospectus;

     

    ●Indirect access to Euroclear is also available to other firms that clear through or maintain a custodial relationship with a Euroclear participant, either directly or indirectly;

     

    ●Securities clearance accounts and cash accounts with Euroclear SA/NV are governed by the Terms and Conditions Governing Use of Euroclear, the related Operating Procedures of Euroclear, and applicable Belgian law (collectively, the “Terms and Conditions”);

     

    ●The Terms and Conditions govern transfers of securities and cash within Euroclear, withdrawals of securities and cash within Euroclear, withdrawals of securities and cash from Euroclear, and receipts of payments with respect to securities in Euroclear. All securities in Euroclear are held on a fungible basis without attribution of specific certificates to specific securities clearance accounts. Euroclear SA/NV acts under the Terms and Conditions only on behalf of Euroclear participants and has no record of or relationship with persons holding through Euroclear participants; and

     

    11

     

    ●Distributions with respect to debt securities held beneficially through Euroclear will be credited to the cash accounts of Euroclear participants in accordance with the Terms and Conditions, to the extent received by the U.S. depositary for Euroclear.

     

    Clearstream has advised us that:

     

    ●It is incorporated under the laws of Luxembourg as a professional depositary and holds securities for its participating organizations and facilitates the clearance and settlement of securities transactions between Clearstream participants through electronic book-entry changes in accounts of Clearstream participants, thereby eliminating the need for physical movement of certificates;

     

    ●Clearstream provides to Clearstream participants, among other things, services for safekeeping, administration, clearance and settlement of internationally traded securities and securities lending and borrowing. Clearstream interfaces with domestic markets in several countries;

     

    ●As a professional depositary, Clearstream is subject to regulation by the Luxembourg Monetary Institute;

     

    ●Clearstream participants are recognized financial institutions around the world, including underwriters, securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations and may include underwriters of debt securities offered by this prospectus;

     

    ●Indirect access to Clearstream is also available to others, such as banks, brokers, dealers and trust companies, that clear through or maintain a custodial relationship with a Clearstream participant either directly or indirectly; and

     

    ●Distributions with respect to the debt securities held beneficially through Clearstream will be credited to cash accounts of Clearstream participants in accordance with its rules and procedures, to the extent received by the U.S. depositary for Clearstream.

     

    We have provided the descriptions herein of the operations and procedures of DTC, Euroclear and Clearstream solely as a matter of convenience. These operations and procedures are solely within the control of DTC, Euroclear and Clearstream and are subject to change by them from time to time. We believe that the sources from which the information in this section and elsewhere in this prospectus concerning DTC, Euroclear, Euroclear SA/NV, Euroclear Clearance Systems S.C., Euroclear’s system, Clearstream and Clearstream’s system has been obtained are reliable, but neither we, any underwriters nor the trustee takes any responsibility for the accuracy of the information.

     

    Initial settlement for the securities will be made in immediately available funds. Secondary market trading between DTC participants will occur in the ordinary way in accordance with DTC’s rules and will be settled in immediately available funds. Secondary market trading between Euroclear participants and/or Clearstream participants will occur in the ordinary way in accordance with the applicable rules and operating procedures of Euroclear and Clearstream, as applicable, and will be settled using the procedures applicable to conventional eurobonds in immediately available funds.

     

    Cross-market transfers between persons holding directly or indirectly through DTC, on the one hand, and directly or indirectly through Euroclear participants or Clearstream participants, on the other, will be effected in DTC in accordance with DTC rules on behalf of the relevant European international clearing system by its U.S. depositary; however, such cross-market transactions will require delivery of instructions to the relevant European international clearing system by the counterparty in such system in accordance with its rules and procedures and within its established deadlines (European time). The relevant European international clearing system will, if the transaction meets its settlement requirements, deliver instructions to its U.S. depositary to take action to effect final settlement on its behalf by delivering or receiving securities in DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Euroclear participants and Clearstream participants may not deliver instructions directly to their respective U.S. depositaries.

     

    Because of time-zone differences, credits of securities received in Euroclear or Clearstream as a result of a transaction with a DTC participant will be made during subsequent securities settlement processing and dated the business day following the DTC settlement date. Credits or any transactions in securities settled during this processing will be reported to the relevant Euroclear or Clearstream participants on that following business day. Cash received in Euroclear or Clearstream as a result of sales of debt securities by or through a Euroclear participant or a Clearstream participant to a DTC participant will be received with value on the DTC settlement date but will be available in the relevant Euroclear or Clearstream cash account only as of the business day following settlement in DTC.

     

    12

     

    Although DTC, Euroclear and Clearstream have agreed to the foregoing procedures to facilitate transfers of securities among participants of DTC, Euroclear and Clearstream, they are under no obligation to perform or continue to perform these procedures and these procedures may be discontinued at any time.

     

    Redemption or Repayment

     

    If there are any provisions regarding redemption or repayment applicable to a debt security, we will describe them in the applicable prospectus supplement. We or our affiliates may purchase debt securities from investors who are willing to sell from time to time, either in the open market at prevailing prices or in private transactions at negotiated prices. Debt securities that we or they purchase may, at our discretion, be held, resold or canceled.

     

    Mergers and Similar Transactions

     

    We are generally permitted under the indenture to merge or consolidate with another corporation or other entity. We are also permitted under the indenture to sell all or substantially all of our assets to another corporation or other entity. With regard to any series of debt securities and other than as set forth in the applicable prospectus supplement, however, we may not take any of these actions unless all the following conditions, among other things, are met:

     

    ●If the successor entity in the transaction is not the Company, the successor entity must be organized as a corporation, limited liability company, partnership or trust, must be organized and validly existing under the laws of the United States, any State thereof or the District of Columbia and must expressly assume our obligations under the debt securities of that series and the indenture with respect to that series.

     

    ●Immediately after the transaction, no default under the debt securities of that series has occurred and is continuing. For this purpose, “default under the debt securities of that series” means an event of default with respect to that series or any event that would be an event of default with respect to that series if the requirements for giving us default notice and for our default having to continue for a specific period of time were disregarded. We describe these matters below under “— Default, Remedies and Waiver of Default.”

     

    If the conditions described above are satisfied with respect to the debt securities of any series, we will not need to obtain the approval of the holders of those debt securities in order to merge or consolidate or to sell all or substantially all our assets. Also, these conditions will apply only if we wish to merge or consolidate with another entity or sell all or substantially all of our assets to another entity. We will not need to satisfy these conditions if we enter into other types of transactions, including any transaction in which we acquire the stock or assets of another entity, any transaction that involves a change of control of the Company but in which we do not merge or consolidate and any transaction in which we sell less than substantially all our assets.

     

    The successor entity will be substituted for the Company with respect to the debt securities of any series and under the indenture with the same effect as if it had been an original party to the indenture, and, except in the case of a lease, the Company will be relieved from any further obligations and covenants under the indenture.

     

    Defeasance, Covenant Defeasance and Satisfaction and Discharge

     

    When we use the term defeasance, we mean discharge from some or all of our obligations under the indenture. If we deposit with the trustee funds or government securities, or if so provided in the applicable prospectus supplement, obligations other than government securities, sufficient to make payments on any series of debt securities on the dates those payments are due and payable and other specified conditions are satisfied, then, at our option, either of the following will occur:

     

    ●we will be discharged from our obligations with respect to the debt securities of such series (“legal defeasance”); or

     

    ●we will be discharged from any covenants we make in the indenture for the benefit of such series and the related events of default will no longer apply to us (“covenant defeasance”).

     

    13

     

    If we defease any series of debt securities, the holders of such securities will not be entitled to the benefits of the indenture, except for our obligations to register the transfer or exchange of such securities, replace stolen, lost or mutilated securities or maintain paying agencies and hold moneys for payment in trust. In case of covenant defeasance, our obligation to pay principal of, and any premium and interest on, the applicable series of debt securities will also survive.

     

    We will be required to deliver to the trustee an opinion of counsel that the deposit and related defeasance would not cause the holders of the applicable series of debt securities to recognize gain or loss for federal income tax purposes. If we elect legal defeasance, that opinion of counsel must be based upon a ruling from the United States Internal Revenue Service or a change in law to that effect.

     

    In addition, we may satisfy and discharge all our obligations under the indenture with respect to debt securities of any series, other than our obligation to register the transfer of and exchange debt securities of that series, provided that we either:

     

    ●deliver all outstanding debt securities of that series to the trustee for cancellation; or

     

    ●all such debt securities not so delivered for cancellation have either become due and payable or will become due and payable at their stated maturity within one year or are to be called for redemption within one year, and in the case of this bullet point, we have deposited with the trustee in trust an amount of cash sufficient to pay the entire indebtedness of such debt securities, including interest to the stated maturity or applicable redemption date.

     

    Default, Remedies and Waiver of Default

     

    Holders of our debt securities will have special rights if an event of default with respect to the holder’s debt security occurs and is continuing, as described in this subsection.

     

    Events of Default

     

    Unless the applicable prospectus supplement says otherwise, when we refer to an event of default with respect to any series of debt securities, we mean any of the following:

     

    ●we do not pay the principal of and any premium on any debt security of that series on the due date;

     

    ●we do not pay interest on any debt security of that series within 30 days after the due date;

     

    ●we do not deposit a sinking fund payment with regard to any debt security of that series within 60 days after the due date, but only if the payment is required under provisions described in the applicable prospectus supplement;

     

    ●we remain in breach of our covenants regarding mergers or sales of substantially all of our assets or any other covenant we make in the indenture for the benefit of the relevant series, for 90 days after we receive a notice of default stating that we are in breach and requiring us to remedy the breach, which notice must be sent by the trustee or the holders of at least 25% in principal amount of the relevant series of debt securities;

     

    ●we file for bankruptcy or other events of bankruptcy, insolvency or reorganization relating to the Company occur; or

     

    ●if the applicable prospectus supplement states that any additional event of default applies to the series, that event of default occurs.

     

    14

     

    We may change, eliminate, or add to the events of default with respect to any particular series or any particular debt security or debt securities within a series, as indicated in the applicable prospectus supplement.

     

    Remedies if an Event of Default Occurs

     

    Except as otherwise specified in the applicable prospectus supplement, if an event of default has occurred with respect to any series of debt securities and has not been cured or waived, the trustee or the holders of not less than 25% in principal amount of all debt securities of that series then outstanding may declare the entire principal amount of the debt securities of that series to be due immediately. Except as otherwise specified in the applicable prospectus supplement, if the event of default occurs because of events in bankruptcy, insolvency or reorganization relating to the Company, the entire principal amount of the debt securities of that series will be automatically accelerated, without any action by the trustee or any holder.

     

    Each of the situations described above is called an acceleration of the stated maturity of the affected series of debt securities. Except as otherwise specified in the applicable prospectus supplement, if the stated maturity of any series is accelerated and a judgment for payment has not yet been obtained, the holders of a majority in principal amount of the debt securities of that series may cancel the acceleration for the entire series.

     

    If an event of default occurs, the trustee will have special duties. In that situation, the trustee will be obligated to use those of its rights and powers under the indenture, and to use the same degree of care and skill in doing so, that a prudent person would use in that situation in conducting his or her own affairs.

     

    Except as described in the prior paragraph, the trustee is not required to take any action under the indenture at the request of any holders unless the holders offer the trustee protection satisfactory to the trustee from expenses and liability. This is called an indemnity. If the trustee is provided with an indemnity satisfactory to it, the holders of a majority in principal amount of all debt securities of the relevant series may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the trustee with respect to that series. These majority holders may also direct the trustee in performing any other action under the indenture with respect to the debt securities of that series. However, the trustee may refuse to follow any direction that conflicts with law or the indenture or that the trustee determines is unduly prejudicial to the rights of other holders (it being understood that the trustee does not have an affirmative duty to ascertain whether or not any such direction unduly prejudices the rights of such holders) or would involve the trustee in personal liability; provided, however, that the trustee may take any other action deemed proper by the trustee that is not inconsistent with such direction.

     

    Before a holder may bypass the trustee and bring its own lawsuit or other formal legal action or take other steps to enforce its rights or protect its interests relating to any debt security, all of the following must occur:

     

    ●the holder of the debt security must give the trustee written notice that an event of default has occurred with respect to the debt securities of such series, and the event of default must not have been cured or waived;

     

    ●the holders of not less than 25% in principal amount of all debt securities of such series must make a written request that the trustee take action because of the default, and they or other holders must offer to the trustee indemnity satisfactory to the trustee against the cost and other liabilities of taking that action;

     

    ●the trustee must not have taken action for 60 days after the above steps have been taken; and

     

    ●during those 60 days, the holders of a majority in principal amount of the debt securities of such series must not have given the trustee directions that are inconsistent with the written request of the holders of not less than 25% in principal amount of the debt securities of such series.

     

    Each holder is entitled at any time, however, to bring a lawsuit for the payment of money due on its debt security on or after its stated maturity (or, if the debt security is redeemable, on or after its redemption date).

     

    Book-entry and other indirect owners should consult their banks or brokers for information on how to give notice or direction to or make a request of the trustee and how to declare or cancel an acceleration of the maturity.

     

    15

     

    Waiver of Default

     

    The holders of not less than a majority in principal amount of the debt securities of any series may waive a default for all debt securities of that series. If this happens, the default will be treated as if it has not occurred. No one can waive a payment default on any debt security, however, without the approval of the particular holder of that debt security.

     

    Annual Information about Defaults to the Trustee

     

    We will furnish each trustee every year a written statement of two of our officers certifying that to their knowledge we are in compliance with the indenture and the debt securities issued under it, or else specifying any default under the indenture.

     

    Modifications and Waivers

     

    There are three types of changes we can make to the indenture and the debt securities or series of debt securities issued under the indenture.

     

    Changes Requiring Each Holder’s Approval

     

    First, there are changes that cannot be made without the approval of each holder of a debt security affected by the change under the indenture, including, among others:

     

    ●changing the stated maturity for any principal or interest payment on such debt security;

     

    ●reducing the principal amount, the amount payable on acceleration of the maturity after a default, the interest rate or the redemption price for such debt security;

     

    ●permitting redemption of such debt security if not previously permitted;

     

    ●impairing any right such holder may have to require purchase of its debt security;

     

    ●if such debt security constitutes a convertible debt security, impairing any right that a holder may have to convert such debt security;

     

    ●changing the currency of any payment on such debt security;

     

    ●changing the place of payment on such debt security;

     

    ●impairing such holder’s right to sue for payment of any amount due on its debt security;

     

    ●reducing the percentage in principal amount of the debt securities of any one or more affected series, taken separately or together, as applicable, and whether comprising the same or different series or less than all of the debt securities of a series, the approval of whose holders is needed to change the indenture or those debt securities or waive our compliance with the indenture or to waive defaults; and

     

    ●changing the provisions of the indenture dealing with modification and waiver in any other respect, except to increase any required percentage referred to above or to add to the provisions that cannot be changed or waived without approval of the holder of each affected debt security.

     

    Changes Not Requiring Approval

     

    The second type of change does not require any approval by holders of the debt securities affected. These changes are limited to clarifications and changes that would not adversely affect any debt securities of any series in any material respect. Nor do we need any approval to make changes that affect only debt securities to be issued under the indenture after the changes take effect. We may also make changes or obtain waivers that do not adversely affect a particular debt security, even if they affect other debt securities. In those cases, we do not need to obtain the approval of the holder of the unaffected debt security; we need only obtain any required approvals from the holders of the affected debt securities. We may also make changes to conform the text of the indenture or any debt securities to any provision of the “Description of Debt Securities” in this prospectus or the comparable section in the applicable prospectus supplement, to the extent such provision was intended to be a verbatim recitation of a provision of such indenture or debt securities.

     

    16

     

    Changes Requiring Majority Approval

     

    Any other change to the indenture and the debt securities issued under the indenture would require the following approval:

     

    ●If the change affects only particular debt securities within a series issued under the indenture, it must be approved by the holders of a majority in principal amount of such particular debt securities; or

     

    ●If the change affects debt securities of more than one series issued under the indenture, it must be approved by the holders of a majority in principal amount of all debt securities of all such series affected by the change, with all such affected debt securities voting together as one class for this purpose and such affected debt securities of any series potentially comprising fewer than all debt securities of such series, in each case, except as may otherwise be provided pursuant to the indenture for all or any particular debt securities of any series. This means that modification of terms with respect to certain securities of a series could be effectuated without obtaining the consent of the holders of a majority in principal amount of other securities of such series that are not affected by such modification.

     

    The same majority approval would be required for us to obtain a waiver of any of our covenants in the indenture. Our covenants include the promises we make about merging or selling substantially all of our assets, which we describe above under “— Mergers and Similar Transactions.” If the holders approve a waiver of a covenant, we will not have to comply with it. The holders, however, cannot approve a waiver of any provision in a particular debt security, or in the indenture as it affects that debt security, that we cannot change without the approval of the holder of that debt security as described above in “—Changes Requiring Each Holder’s Approval,” unless that holder approves the waiver.

     

    We may issue particular debt securities or a particular series of debt securities, as applicable, that are entitled, by their terms, to separately approve matters (for example, modification or waiver of provisions in the indenture) that would also, or otherwise, require approval of holders of a majority in principal amount of all affected debt securities of all affected series issued under the indenture voting together as a single class. Any such affected debt securities or series of debt securities would be entitled to approve such matters (i) pursuant to such special rights by consent of holders of a majority in principal amount of such affected debt securities or series of debt securities voting separately as a class and (ii) in addition, as described above, except as may otherwise be provided pursuant to the indenture for such debt securities or series of debt securities, by consent of holders of a majority in principal amount of such affected debt securities or series of debt securities and all other affected debt securities of all series issued under the indenture voting together as one class for this purpose. We may issue series or debt securities of a series having these or other special voting rights without obtaining the consent of or giving notice to holders of outstanding debt securities or series.

     

    Book-entry and other indirect owners should consult their banks or brokers for information on how approval may be granted or denied if we seek to change an indenture or any debt securities or request a waiver.

     

    Special Rules for Action by Holders

     

    Only holders of outstanding debt securities of the applicable series will be eligible to take any action under the indenture, such as giving a notice of default, declaring an acceleration, approving any change or waiver or giving the trustee an instruction with respect to debt securities of that series. Also, we will count only outstanding debt securities in determining whether the various percentage requirements for taking action have been met. Any debt securities owned by us or any of our affiliates or surrendered for cancellation or for payment or redemption, for which money has been set aside in trust, are not deemed to be outstanding. Any required approval or waiver must be given by written consent.

     

    In some situations, we may follow special rules in calculating the principal amount of debt securities that are to be treated as outstanding for the purposes described above. This may happen, for example, if the principal amount is payable in a non-U.S. dollar currency, increases over time or is not to be fixed until maturity.

     

    17

     

    We will generally be entitled to set any day as a record date for the purpose of determining the holders that are entitled to take action under the indenture. In certain limited circumstances, only the trustee will be entitled to set a record date for action by holders. If we or the trustee sets a record date for an approval or other action to be taken by holders, that vote or action may be taken only by persons or entities who are holders on the record date and must be taken during the period that we specify for this purpose, or that the trustee specifies if it sets the record date. We or the trustee, as applicable, may shorten or lengthen this period from time to time. This period, however, may not extend beyond the 180th day after the record date for the action. In addition, record dates for any global debt security may be set in accordance with procedures established by the depositary from time to time. Accordingly, record dates for global debt securities may differ from those for other debt securities.

     

    Form, Exchange and Transfer

     

    If any debt securities cease to be issued in registered global form, they will be issued:

     

    ●only in fully registered form;

     

    ●without interest coupons; and

     

    ●unless we indicate otherwise in the applicable prospectus supplement, in denominations of $1,000 and integral multiples of $1,000.

     

    Holders may exchange their debt securities for debt securities of smaller denominations or combined into fewer debt securities of larger denominations, as long as the total principal amount is not changed. Holders may not exchange debt securities for securities of a different series or having different terms, unless the applicable prospectus supplement and the supplemental indenture with respect to such debt securities provide for such exchange.

     

    Holders may exchange or transfer their debt securities at the office of the trustee. They may also replace lost, stolen, destroyed or mutilated debt securities at that office. We have appointed the trustee to act as our agent for registering debt securities in the names of holders and transferring and replacing debt securities. We may appoint another entity to perform these functions or perform them ourselves.

     

    Holders will not be required to pay a service charge to transfer or exchange their debt securities, but they may be required to pay for any tax or other governmental charge associated with the exchange or transfer. The transfer or exchange, and any replacement, will be made only if our transfer agent is satisfied with the holder’s proof of legal ownership. The transfer agent may require an indemnity before replacing any debt securities.

     

    If we have designated additional transfer agents for a debt security, they will be named in the applicable prospectus supplement. We may appoint additional transfer agents or cancel the appointment of any particular transfer agent. We may also approve a change in the office through which any transfer agent acts.

     

    If the debt securities of any series are redeemable and we redeem less than all those debt securities, we may block the transfer or exchange of those debt securities during the period beginning 15 days before the day we mail the notice of redemption and ending on the day of that mailing, in order to freeze the list of holders to prepare the mailing. We may also refuse to register transfers of or exchange any debt security selected for redemption, except that we will continue to permit transfers and exchanges of the unredeemed portion of any debt security being partially redeemed.

     

    If a debt security is issued as a global debt security, only DTC or other depositary will be entitled to transfer and exchange the debt security as described in this subsection because the depositary will be the sole holder of the debt security.

     

    The rules for exchange described above apply to exchange of debt securities for other debt securities of the same series and kind. If a debt security is convertible, exercisable or exchangeable into or for a different kind of security, such as one that we have not yet issued, or for other property, the rules governing that type of conversion, exercise or exchange will be described in the applicable prospectus supplement.

     

    18

     

    Payments

     

    We will pay interest, principal and other amounts payable with respect to the debt securities of any series to the holders of record of those debt securities as of the record dates and otherwise in the manner specified below or in the prospectus supplement for that series.

     

    We will make payments on a global debt security in accordance with the applicable policies of the depositary as in effect from time to time. Under those policies, we will pay directly to the depositary, or its nominee, and not to any indirect owners who own beneficial interests in the global debt security. An indirect owner’s right to receive those payments will be governed by the rules and practices of the depositary and its participants.

     

    We will make payments on a debt security in non-global, registered form as follows. We will pay interest that is due on an interest payment date by check mailed on the interest payment date to the holder at his or her address shown on the trustee’s records as of the close of business on the regular record date. We will make all other payments by check at the paying agent described below, against surrender of the debt security. All payments by check will be made in next-day funds — i.e., funds that become available on the day after the check is cashed.

     

    Alternatively, if a non-global debt security has a face amount of at least $1,000,000 and the holder asks us to do so, we will pay any amount that becomes due on the debt security by wire transfer of immediately available funds to an account at a bank in New York City, on the due date. To request wire payment, the holder must give the paying agent appropriate wire transfer instructions at least five business days before the requested wire payment is due. In the case of any interest payment due on an interest payment date, the instructions must be given by the person or entity who is the holder on the relevant regular record date. In the case of any other payment, payment will be made only after the debt security is surrendered to the paying agent. Any wire instructions, once properly given, will remain in effect unless and until new instructions are given in the manner described above.

     

    Book-entry and other indirect owners should consult their banks or brokers for information on how they will receive payments on their debt securities.

     

    Regardless of who acts as paying agent, subject to applicable escheatment law, all money paid by us to a paying agent that remains unclaimed at the end of two years after the amount is due to a holder will be repaid to us. After that two-year period, the holder may look only to us for payment and not to the trustee, any other paying agent or anyone else.

     

    Paying Agents

     

    We may appoint one or more financial institutions to act as our paying agents, at whose designated offices debt securities in non-global entry form may be surrendered for payment at their maturity. We call each of those offices a paying agent. We may add, replace or terminate paying agents from time to time. We may also choose to act as our own paying agent. We will specify in the prospectus supplement for a debt security the initial location of each paying agent for that debt security. We must notify the trustee of changes in the paying agents.

     

    Notices

     

    Notices to be given to holders of a global debt security will be given only to the depositary, in accordance with its applicable policies as in effect from time to time. Notices to be given to holders of debt securities not in global form will be sent by mail to the respective addresses of the holders as they appear in the trustee’s records, and will be deemed given when mailed. Neither the failure to give any notice to a particular holder, nor any defect in a notice given to a particular holder, will affect the sufficiency of any notice given to another holder.

     

    Book-entry and other indirect owners should consult their banks or brokers for information on how they will receive notices.

     

    Our Relationship with the Trustee

     

    The prospectus supplement for a debt security will describe any material relationships we may have with the trustee with respect to that debt security.

     

    19

     

    DESCRIPTION OF WARRANTS

     

    We may issue warrants for the purchase of our equity or debt securities. Warrants may be offered separately or together with other securities, as the case may be, and may be attached to or separate from any offered securities. Each series of warrants will be issued under a separate warrant indenture to be entered into between the Company and one or more banks or trust companies acting as warrant agent. The applicable prospectus supplement will include details of the terms and conditions of the warrants being offered. The warrant agent will act solely as the Company’s agent and will not assume a relationship of agency with any holders of warrant certificates or beneficial owners of warrants. The following sets forth certain general terms and provisions of the warrants that may be offered under this prospectus. The specific terms of the warrants, and the extent to which the general terms described in this section apply to those warrants, will be set forth in the applicable prospectus supplement. If applicable, the Company will file with the SEC as exhibits to the registration statement of which this prospectus is a part, or will incorporate by reference from a Current Report on Form 8-K filed with the SEC, any warrant indenture or form of warrant describing the terms and conditions of such warrants that the Company is offering before the issuance of such warrants.

     

    The particular terms of each issue of warrants will be described in the related prospectus supplement. This description will include, where applicable:

     

    ●the designation and aggregate number of warrants;

     

    ●the price at which the warrants will be offered;

     

    ●the currency or currencies in which the warrants will be offered;

     

    ●the amount of warrants outstanding;

     

    ●the designation and terms of the shares of Common Stock purchasable or debt securities that may be issued upon exercise of the warrants;

     

    ●the date on which the right to exercise the warrants will commence and the date on which the right will expire;

     

    ●the number of shares of Common Stock that may be purchased upon exercise of each warrant and the price at which and currency or currencies in which the shares of Common Stock may be purchased upon exercise of each warrant, including provisions for changes to or adjustments in the exercise price;

     

    ●the principal amount of debt securities that may be purchased upon exercise of a warrant and the price at which the debt securities may be purchased upon exercise;

     

    ●the designation and terms of any securities with which the warrants will be offered, if any, and the number of the warrants that will be offered with each security;

     

    ●the date or dates, if any, on or after which the warrants and the related securities will be transferable separately;

     

    ●whether the warrants will be subject to redemption or call and, if so, the terms of such redemption or call provisions;

     

    ●material tax consequences of owning the warrants; and

     

    ●any other material terms or conditions of the warrants.

     

    Prior to the exercise of their warrants, holders of warrants will not have any of the rights of holders of Common Stock, preferred stock or debt securities issuable upon exercise of the warrants. The Company reserves the right to set forth in a prospectus supplement specific terms of the warrants that are not within the options and parameters set forth in this prospectus. In addition, to the extent that any particular terms of the warrants described in a prospectus supplement differ from any of the terms described in this prospectus, the description of such terms set forth in this prospectus shall be deemed to have been superseded by the description of such differing terms set forth in such prospectus supplement with respect to such warrants.

     

    20

     

    DESCRIPTION OF UNITS

     

    The Company may issue units comprised of one or more of the other securities described in this prospectus in any combination. 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, if any, under which a unit is issued may provide that the securities comprising the unit may not be held or transferred separately, at any time or at any time before a specified date. If applicable, the Company will file with the SEC as exhibits to the registration statement of which this prospectus is a part, or will incorporate by reference from a Current Report on Form 8-K filed with the SEC, any unit agreement describing the terms and conditions of such units that Hyliion is offering before the issuance of such units.

     

    The particular terms and provisions of units offered by any prospectus supplement, and the extent to which the general terms and provisions described below may apply thereto, will be described in the prospectus supplement filed in respect of such units. This description will include, where applicable:

     

    ●the designation and aggregate number of units offered;

     

    ●the price at which the units will be offered, including provisions for changes to or adjustments in price at which units will be offered;

     

    ●the currency or currency unit in which the units are denominated;

     

    ●the amount of units outstanding;

     

    ●the 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;

     

    ●the number of securities that may be purchased upon exercise of each unit and the price at which and currency or currency unit in which that amount of securities may be purchased upon exercise of each unit;

     

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

     

    ●any other material terms, conditions and rights (or limitations on such rights) of the units.

     

    The Company reserves the right to set forth in a prospectus supplement specific terms of the units that are not within the options and parameters set forth in this prospectus. In addition, to the extent that any particular terms of the units described in a prospectus supplement differ from any of the terms described in this prospectus, the description of such terms set forth in this prospectus shall be deemed to have been superseded by the description of such differing terms set forth in such prospectus supplement with respect to such units.

     

    21

     

    PLAN OF DISTRIBUTION

     

    We may sell securities pursuant to this prospectus and any accompanying prospectus supplement in and outside the United States (1) through underwriters, brokers or dealers, (2) directly to purchasers, including our affiliates and stockholders, (3) through agents, (4) in short or long transactions, (5) through put or call option transactions relating to our Common Stock, (6) in “at the market offerings” within the meaning of Rule 415(a)(4) of the Securities Act to or through a market maker or into an existing trading market, or in a rights offering or a securities exchange or otherwise, (7) through a combination of any of these methods or (8) through any other method described in the applicable prospectus supplement. The prospectus supplement, if required, will include the following information:

     

    ●the terms of the offering;

     

    ●any public offering price;

     

    ●the names of any underwriters, dealers or agents;

     

    ●the name or names of any managing underwriter or underwriters;

     

    ●the purchase price of the securities;

     

    ●the estimated net proceeds to us from the sale of the securities;

     

    ●any options (whether or not for over-allotments) under which the underwriters may purchase additional shares of Common Stock from us;

     

    ●any delayed delivery arrangements;

     

    ●any underwriting discounts, concessions, commissions or agency fees and other items constituting compensation to underwriters, dealers, or agents;

     

    ●any discounts or concessions allowed or re-allowed or paid by underwriters or dealers to other dealers; or

     

    ●any securities exchange or market on which the securities offered in the prospectus supplement may be listed.

     

    If we use underwriters for a sale of securities, the underwriters will acquire the securities for their own account for resale to the public, either on a firm commitment basis or a best efforts basis. The underwriters may resell the securities in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. Underwriters may offer the securities to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. If an underwriter or underwriters are used in the sale of securities hereunder, an underwriting agreement will be executed with the underwriter or underwriters at the time an agreement for sale is reached. Unless we inform you otherwise in the applicable prospectus supplement, the obligations of the underwriters to purchase the securities will be subject to certain conditions. We may change from time to time any public offering price and any discounts or concessions the underwriters allow or pay to dealers.

     

    During and after an offering through underwriters, the underwriters may purchase and sell the securities in the open market. These transactions may include overallotment and stabilizing transactions and purchases to cover syndicate short positions created in connection with the offering. The underwriters may also impose a penalty bid, which means that selling concessions allowed to syndicate members or other broker-dealers for the offered securities sold for their account may be reclaimed by the syndicate if the offered securities are repurchased by the syndicate in stabilizing or covering transactions. These activities may stabilize, maintain, or otherwise affect the market price of the offered securities, which may be higher than the price that might otherwise prevail in the open market. If commenced, the underwriters may discontinue these activities at any time.

     

    22

     

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

     

    If dealers are used for the sale of securities, we, or an underwriter, will sell the securities to them as principals. The dealers may then resell those securities to the public at varying prices determined by the dealers at the time of resale. We will include in the applicable prospectus supplement the names of the dealers and the terms of the transaction.

     

    We may also sell the securities through agents designated from time to time. In the applicable prospectus supplement, we will name any agent involved in the offer or sale of the offered securities, and we will describe any commissions payable to the agent. Unless we inform you otherwise in the applicable prospectus supplement, any agent will agree to use its reasonable best efforts to solicit purchases for the period of its appointment.

     

    We may sell the securities directly in transactions not involving underwriters, dealers, or agents.

     

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

     

    Underwriters, dealers, and agents that participate in the distribution of the securities may be underwriters as defined in the applicable securities laws and any discounts or commissions they receive from us and any profit on their resale of the securities may be treated as underwriting discounts and commissions under the applicable securities laws. We will identify in the applicable prospectus supplement any underwriters, dealers, or agents and will describe their compensation. We may have agreements with the underwriters, dealers, and agents to indemnify them against specified civil liabilities, including liabilities under the applicable securities laws.

     

    Underwriters, dealers, and agents may engage in transactions with or perform services for us in the ordinary course of their businesses for which they may receive customary fees and reimbursement of expenses.

     

    We may use underwriters with whom we have a material relationship. We will describe the nature of such relationship in the applicable prospectus supplement.

     

    Under the securities laws of some states, the securities offered by this prospectus may be sold in those states only through registered or licensed brokers or dealers.

     

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

     

    If we so indicate in the prospectus supplement, we may authorize agents, underwriters or dealers to solicit offers from certain types of institutions to purchase securities from us at the public offering price under delayed delivery contracts. These contracts would provide for payment and delivery on a specified date in the future. The contracts would be subject only to those conditions described in the prospectus supplement. The prospectus supplement will describe the commission payable for solicitation of those contracts.

     

    23

     

    LEGAL MATTERS

     

    The validity of any securities offered by this prospectus will be passed upon for us by Vinson & Elkins L.L.P., New York, New York. Any underwriters or agents will be advised about other issues relating to any offering by their own counsel to be named in an applicable prospectus supplement.

    Item 15. Indemnification of Directors and Officers.

     

    We are incorporated under the laws of the State of Delaware. Section 145(a) of the DGCL provides, in general, that a corporation may indemnify any person who was or is a party to 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 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 that the Court of Chancery or other adjudicating court shall deem proper. Per Section 145(c) of the DGCL, where an officer or director is successful on the merits or otherwise in the defense of any action referred to above, the corporation must indemnify him or her against the expenses (including attorneys’ fees) actually and reasonably incurred.

     

    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.

     

    II-1

     

    Additionally, Section 102(b)(7) of the DGCL provides that a certificate of incorporation may contain a provision eliminating or limiting the personal liability of a director of the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, provided that such provisions may not eliminate or limit the liability of a director (i) for any breach of the director’s duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 (relating to liability for unauthorized acquisitions or redemptions of, or dividends on, capital stock) of the DGCL, or (iv) for any transaction from which the director derived an improper personal benefit. Our Certificate of Incorporation eliminates our directors’ liability to the fullest extent permitted under the DGCL. The DGCL provides that directors of a corporation will not be personally liable for monetary damages for breach of their fiduciary duties as directors, except for liability:

     

    ●for any transaction from which the director derives an improper personal benefit;

     

    ●for any act or omission not in good faith or that involves intentional misconduct or a knowing violation of law;

     

    ●for any unlawful payment of dividends or redemption of shares; or

     

    ●for any breach of a director’s duty of loyalty to the corporation or its stockholders.

     

    If the DGCL is amended to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of the Company’s directors will be eliminated or limited to the fullest extent permitted by the DGCL, as so amended.

     

    In addition, we have entered into separate indemnification agreements with our directors and officers. These agreements, among other things, require us to indemnify our directors and officers for certain expenses, including attorneys’ fees, judgments, fines, and settlement amounts incurred by a director or officer in any action or proceeding arising out of their services as one of our directors or officers or any other company or enterprise to which the person provides services at our request.

     

    We maintain a directors’ and officers’ insurance policy pursuant to which our directors and officers are insured against liability for actions taken in their capacities as directors and officers.

    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;

     

    (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 SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

     

    (iii)to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

     

    provided, however, that: Paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) of this section do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act, 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, 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.

     

    (5)That, for the purpose of determining liability under the Securities Act 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 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.

     

    (6)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-4

     

    (ii)Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

     

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

     

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

     

    (b)That, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

     

    (h)Insofar as indemnification for liabilities arising under the Securities Act 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 SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

     

    (i)

     

    (1)For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b) (1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.

     

    (2)For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus 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.

     

    (j)The undersigned registrant hereby undertakes to file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of Section 310 of the Trust Indenture Act in accordance with the rules and regulations prescribed by the Commission under Section 305(b)(2) of the Trust Indenture Act.

     

    II-5

     

    SIGNATURES

     

    Pursuant to the requirements of the Securities Act of 1933, the registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized in the City of Cedar Park, State of Texas on February 24, 2026.
