About Ramaco Resources, Inc.

Ramaco Resources, Inc. is a Delaware corporation formed in October 2016. Our Class A common stock and Class B common stock are listed on the Nasdaq Global Select Market under the symbols “METC” and “METCB,” respectively. Our 8.250% Senior Notes due 2030 (the “2030 Notes”) issued on July 31, 2025, in aggregate principal amount of $57 million, are listed on the Nasdaq Global Select Market under the symbol “METCI”.

Our 8.375% Senior Notes due 2029 (the “2029 Notes”) are listed on the Nasdaq Global Select Market under the symbol “METCZ”. There was $57.5 million in aggregate principal amount of our 2029 Notes issued and outstanding as of March 31, 2025. Our 9.00% Senior Notes due 2026 (the “2026 Notes”), were listed on the Nasdaq Global Select Market under the symbol “METCL”, and were redeemed on August 4, 2025, with the proceeds received from the sale of the 2030 Notes. There was $34.5 million in aggregate principal amount of our 2026 Notes issued and outstanding as of March 31, 2025.

We are an operator and developer of high-quality, low-cost metallurgical coal in southern West Virginia and southwestern Virginia. Our executive offices are located in Lexington, Kentucky, with operational offices in Charleston, West Virginia and Sheridan, Wyoming. We are a pure play metallurgical coal company with 66 million reserve tons and 1,352 million of measured and indicated resource tons of high-quality metallurgical coal.

Our development portfolio primarily includes the following properties: Elk Creek, Berwind, Knox Creek and Maben. We believe each of these properties possesses geologic and logistical advantages that make our coal among the lowest delivered-cost U.S. metallurgical coal to our domestic target customer base, North American blast furnace steel mills and coke plants, as well as international metallurgical coal consumers. We also control mineral deposits near Sheridan, Wyoming as part of the Company’s initiatives regarding the potential recovery of rare earth elements as well as the potential commercialization of coal-to-carbon-based products and materials. As of June 2025, we have proceeded with mine development of our rare earth element and critical mineral Brook Mine near Sheridan, Wyoming. That mine will produce representative ore material for short term pilot-scale testing of the feedstock, with the goal of ultimately processing such material into rare earth and critical minerals oxides at a full-scale commercial processing facility.

We seek to increase stockholder value through sustained earnings growth, cash flow generation and dividends by:

Developing and Operating Our Metallurgical Coal Properties. We have 66 million reserve tons and 1,352 million measured and indicated resource tons of high-quality metallurgical coal with attractive quality characteristics across high-volatility and low-volatility segments. This geologically advantaged resource and reserve base allows for flexible capital spending in challenging market conditions.

We plan to complete development of our existing properties and increase annual production over the next few years to as much as seven million clean tons of metallurgical coal, subject to market conditions, permitting and additional capital deployment. We may also acquire additional reserves or infrastructure that contribute to our focus on advantaged geology and lower costs.

TABLE OF CONTENTS

Being a Low-Cost U.S. Producer of Metallurgical Coal. Our reserve base presents advantaged geologic characteristics such as relatively thick coal seams at the deep mines, a low effective mining ratio at the surface mines, and desirable metallurgical coal quality. These characteristics contribute to a production profile that has a cash cost of production that is significantly below most U.S. metallurgical coal producers.

Maintaining a Conservative Capital Structure and Prudently Managing the Business for the Long Term. We are committed to maintaining a conservative capital structure with a reasonable amount of debt that will afford us the financial flexibility to execute our business strategies on an ongoing basis.

Enhancing Coal Purchase Opportunities. Depending on market conditions, we purchase coal from other independent producers. Purchased coal is complementary from a blending standpoint with our produced coals or it may also be sold as an independent product.

Demonstrating Excellence in Safety and Environmental Stewardship. We are committed to complying with both regulatory and our high standards for environmental and employee health and safety requirements. We believe that business excellence is achieved through the pursuit of safer and more productive work practices.

Advancing our Initiatives in Rare Earth Elements, Critical Minerals, and Advanced Carbon Products. We are also focused on the development of rare earth elements and critical minerals, including gallium, scandium and germanium which were recently banned for export to the United States by China, as well as the potential commercialization of coal-to-carbon-based products and materials. These initiatives provide additional growth opportunities in future periods. We had a ribbon cutting at our carbon ore and rare earth mine, the Brook Mine, on July 11, 2025, and development of this mine and overall project is proceeding.

Credit Agreement

On August 5, 2025, we entered into a fourth amendment to the Second Amended and Restated Credit and Security Agreement dated February 15, 2023, by and among the Company, as borrower, KeyBank National Association (“KeyBank”) and multiple lending parties thereto (the “Credit Agreement”). This fourth amendment to the Credit Agreement removed all negative covenants relating to the issues of equity securities by the Company.

Moreover, we operate in a very competitive and rapidly changing environment and additional risks may arise from time to time. It is not possible for our management to predict all of the risks associated with our business, including those described under the heading “Risk Factors” included in our Annual Report on Form 10-K, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. Although we believe that our plans, intentions and expectations reflected in or suggested by the forward-looking statements we make in this prospectus are reasonable, we can give no assurance that these plans, intentions or expectations will be achieved or occur, and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements. Given these risks and uncertainties, investors should not place undue reliance on forward-looking statements as a prediction of actual results.

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

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

All outstanding shares of our common stock are fully paid and non-assessable.

Certain Anti-Takeover Provisions of Delaware Law, the Company’s Certificate of Incorporation and Bylaws

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

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

Delaware Law

We are subject to the provisions of Section 203 of the DGCL, regulating corporate takeovers. In general, those provisions prohibit a Delaware corporation, including those whose securities are listed for trading on the Nasdaq, from engaging in any business combination with any interested stockholder for a period of three years following the date that the stockholder became an interested stockholder, unless:

•

the transaction is approved by the Board before the date the interested stockholder attained that status;

•

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

•

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

TABLE OF CONTENTS

Certificate of Incorporation and Bylaws

Provisions of our certificate of incorporation and our bylaws, each as amended, may delay or discourage transactions involving an actual or potential change in control or change in our management, including transactions in which stockholders might otherwise receive a premium for their shares, or transactions that our stockholders might otherwise deem to be in their best interests. Therefore, these provisions could adversely affect the price of our common stock.

Among other things, our certificate of incorporation and bylaws:

•

establishes advance notice procedures with regard to stockholder proposals relating to the nomination of candidates for election as directors or new business to be brought before meetings of our stockholders. These procedures provide that notice of stockholder proposals must be timely given in writing to our corporate secretary prior to the meeting at which the action is to be taken. Generally, to be timely, notice must be received at our principal executive offices not less than 90 days nor more than 120 days prior to the first anniversary date of the annual meeting for the preceding year. Our bylaws specify the requirements as to form and content of all stockholders’ notices. These requirements may preclude stockholders from bringing matters before the stockholders at an annual or special meeting;

•

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

•

provides our Board the ability to authorize undesignated preferred stock. This ability makes it possible for our Board to issue, without stockholder approval, preferred stock with voting or other rights or preferences that could impede the success of any attempt to change control of us. These and other provisions may have the effect of deferring hostile takeovers or delaying changes in control or management of our company;

•

provides that the authorized number of directors may be changed only by resolution of the Board;

•

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

•

provides that our certificate of incorporation and bylaws may be amended by the affirmative vote of the holders of at least two-thirds of our then outstanding common stock;

•

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

•

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

•

provides that we renounce any interest in existing and future investments in other entities by, or the business opportunities of, Yorktown Partners LLC (“Yorktown”) and Energy Capital Partners Mezzanine, LLC (“ECP” and together with Yorktown, the “Sponsors”) or any of their officers, directors, agents, stockholders, members, partners, affiliates and subsidiaries (other than our directors that are presented business opportunities in their capacity as our directors) and that they have no obligation to offer us those investments or opportunities; and

•

provides that our bylaws can be amended by the Board.

Forum Selection

Our certificate of incorporation provides that unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware will, to the fullest extent permitted by applicable law, be the sole and exclusive forum for:

TABLE OF CONTENTS

•

any derivative action or proceeding brought on our behalf;

•

any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers, employees or agents to us or our stockholders;

•

any action asserting a claim against us or any director or officer or other employee of ours arising pursuant to any provision of the DGCL, our certificate of incorporation or our bylaws; or

•

any action asserting a claim against us or any director or officer or other employee of ours that is governed by the internal affairs doctrine, in each such case subject to such Court of Chancery having personal jurisdiction over the indispensable parties named as defendants therein.

Our certificate of incorporation also provides that any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock will be deemed to have notice of, and to have consented to, this forum selection provision. Although we believe these provisions will benefit us by providing increased consistency in the application of Delaware law for the specified types of actions and proceedings, the provisions may have the effect of discouraging lawsuits against our directors, officers, employees and agents. 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.

Limitation of Liability and Indemnification Matters

Our certificate of incorporation limits the liability of our directors for monetary damages for breach of their fiduciary duty as directors, except for liability that cannot be eliminated under the DGCL. Delaware law provides that directors of a company will not be personally liable for monetary damages for breach of their fiduciary duty as directors, except for liabilities:

•

for any breach of their duty of loyalty to us or our stockholders;

•

for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law;

•

for unlawful payment of dividend or unlawful stock repurchase or redemption, as provided under Section 174 of the DGCL; or

•

for any transaction from which the director derived an improper personal benefit.

Any amendment, repeal or modification of these provisions will be prospective only and would not affect any limitation on liability of a director for acts or omissions that occurred prior to any such amendment, repeal or modification.

Our bylaws also provide that we will indemnify our directors and officers to the fullest extent permitted by Delaware law. Our bylaws also permit us to purchase insurance on behalf of any officer, director, employee or other agent for any liability arising out of that person’s actions as our officer, director, employee or agent, regardless of whether Delaware law would permit indemnification. We have entered into and intend to enter into indemnification agreements with each of our current and future directors and officers. These agreements require us to indemnify these individuals to the fullest extent permitted under Delaware law against liability that may arise by reason of their service to us, and to advance expenses incurred as a result of any proceeding against them as to which they could be indemnified. We believe that the limitation of liability provision that are in our certificate of incorporation and the indemnification agreements facilitate our ability to continue to attract and retain qualified individuals to serve as directors and officers.

Transfer Agent and Registrar

Computershare Trust Company, N.A. acts as our transfer and distribution agent and registrar for our shares of common stock.

Listing

Our Class A common stock and Class B common stock are listed on the Nasdaq under the symbols “METC” and “METCB,” respectively.

TABLE OF CONTENTS

DESCRIPTION OF PREFERRED STOCK

General

Our certificate of incorporation provides that we may issue up to 50,000,000 shares of preferred stock, $0.01 par value per share. As of the date of this prospectus, we had no outstanding shares of preferred stock.

We may issue preferred stock. Preferred stock may be issued independently or together with any other securities and may be attached to or separate from the securities. The following description of the preferred stock sets forth general terms and provisions of the preferred stock to which any prospectus supplement may relate. The statements below describing the preferred stock are in all respects subject to and qualified in their entirety by reference to the applicable provisions of our certificate of incorporation and bylaws and any applicable designation designating terms of a series of preferred stock. The issuance of preferred stock could adversely affect the voting power, dividend rights and other rights of holders of Class A common stock and Class B common stock.

Although our Board does not have this intention at the present time, it or a duly authorized committee could establish another series of preferred stock, that could, depending on the terms of the series, delay, defer or prevent a transaction or a change in control of our company that might involve a premium price for the Class A common stock or Class B common stock or otherwise be in the best interest of the holders thereof.

Terms

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

Reference is made to the applicable prospectus supplement relating to the series of preferred stock offered thereby for the specific terms thereof, including:

•

the designation of the class and/or series of preferred stock;

•

the number of shares of the preferred stock, the liquidation preference per share of the preferred stock and the offering price of the preferred stock;

•

the dividend rate(s), period(s) and/or payment day(s) or method(s) of calculation thereof applicable to the preferred stock;

•

the date from which dividends on the preferred stock shall accumulate, if applicable;

•

the procedures for any auction and remarketing, if any, for the preferred stock;

•

the provision for a sinking fund, if any, for the preferred stock;

•

the provision for redemption, if applicable, of the preferred stock;

•

any listing of the preferred stock on any securities exchange;

•

the terms and conditions, if applicable, upon which the preferred stock may or will be convertible into our Class A common stock or Class B common stock, including the conversion price or manner of calculation thereof;

•

the relative ranking and preferences of the preferred stock as to dividend rights and rights upon liquidation, dissolution or winding up of our affairs;

•

whether interests in the shares of preferred stock will be represented by depositary shares;

•

any limitations on ownership and restrictions on transfer;

TABLE OF CONTENTS

•

any limitations on the issuance of any class or series of preferred stock ranking senior or equal to the series of preferred stock being offered as to dividend rights and rights upon liquidation, dissolution or the winding up of our affairs;

•

a discussion of U.S. federal income tax considerations applicable to the preferred stock; and

•

any other specific terms, preferences, conversion and other rights, voting powers, restrictions, limitations as to dividends and other distributions, qualifications and terms and conditions of redemption of the preferred stock.

The terms of each class or series of preferred stock will be described in any prospectus supplement related to such class or series of preferred stock and will contain a discussion of any material Delaware law and may describe certain material U.S. federal income tax considerations applicable to the preferred stock.

Registrar and Transfer Agent

We will name the registrar and transfer agent for the preferred stock in the applicable prospectus supplement.

TABLE OF CONTENTS

DESCRIPTION OF DEPOSITARY SHARES

We may, at our option, elect to offer depositary shares rather than full shares of preferred stock. In the event such option is exercised, each of the depositary shares will represent ownership of and entitlement to all rights and preferences of a fraction of a share of preferred stock of a specified class or series (including dividend, voting, redemption and liquidation rights). The applicable fraction will be specified in a prospectus supplement. The shares of preferred stock represented by the depositary shares will be deposited with a depositary named in the applicable prospectus supplement, under a deposit agreement, among our company, the depositary and the holders of the certificates evidencing depositary shares, or depositary receipts. Depositary receipts will be delivered to those persons purchasing depositary shares in the offering. The depositary will be the transfer agent, registrar and dividend disbursing agent for the depositary shares. Holders of depositary receipts agree to be bound by the deposit agreement, which requires holders to take certain actions such as filing proof of residence and paying certain charges. The form of the deposit agreement and the form of the depositary receipt will be filed with the SEC and incorporated by reference as an exhibit to the registration statement of which this prospectus is a part.

The summary of terms of the depositary shares contained in this prospectus does not purport to be complete and is subject to, and qualified in its entirety by, the provisions of the deposit agreement and the form of designation for the applicable class or series of preferred stock. While the deposit agreement relating to a particular class or series of preferred stock may have provisions applicable solely to that class or series of preferred stock, all deposit agreements relating to preferred stock we issue will include the provisions described below.

Dividends and Other Distributions

Each time we pay a cash dividend or make any other type of cash distribution with regard to preferred stock of a class or series, the depositary will distribute to the holder of record of each depositary share relating to that class or series of preferred stock an amount equal to the dividend or other distribution per depositary share that the depositary receives. If there is a distribution of property other than cash, the depositary either will distribute the property to the holders of depositary shares in proportion to the depositary shares held by each of them, or the depositary will, if we approve, sell the property and distribute the net proceeds to the holders of the depositary shares in proportion to the depositary shares held by them.

Withdrawal of Preferred Stock

A holder of depositary shares will be entitled to receive, upon surrender of depositary receipts representing depositary shares, the number of whole or fractional shares of the applicable class or series of preferred stock and any money or other property to which the depositary shares relate.

Redemption of Depositary Shares

Whenever we redeem shares of preferred stock held by a depositary, the depositary will be required to redeem, on the same redemption date, depositary shares constituting, in total, the number of shares of preferred stock held by the depositary which we redeem, subject to the depositary’s receiving the redemption price of those shares of preferred stock. If fewer than all the depositary shares relating to a class or series of preferred stock are to be redeemed, the depositary shares to be redeemed will be selected by lot or by another method we determine to be equitable.

Voting

Any time we send a notice of meeting or other materials relating to a meeting to the holders of a class or series of preferred stock to which depositary shares relate, we will provide the depositary with sufficient copies of those materials so they can be sent to all holders of record of the applicable depositary shares, and the depositary will send those materials to the holders of record of the depositary shares on the record date for the meeting. The depositary will solicit voting instructions from holders of depositary shares and will vote or not vote the preferred stock to which the depositary shares relate in accordance with those instructions.

TABLE OF CONTENTS

Liquidation Preference

Upon our liquidation, dissolution or winding up, the holder of each depositary share will be entitled to what the holder of the depositary share would have received if the holder had owned the number of shares (or a fraction of a share) of preferred stock which is represented by the depositary share.

Conversion

If shares of a class or series of preferred stock are convertible into Class A common stock or Class B common stock or other of our securities or property, holders of depositary shares relating to that class or series of preferred stock will, if they surrender depositary receipts representing depositary shares and appropriate instructions to convert them, receive the shares of Class A common stock or Class B common stock or other securities or property into which the number of shares (or fractions of shares) of preferred stock to which the depositary shares relate could at the time be converted.

Amendment and Termination of a Deposit Agreement

We and the depositary may amend a deposit agreement, except that an amendment which materially and adversely affects the rights of holders of depositary shares, or would be materially and adversely inconsistent with the rights granted to the holders of the preferred stock to which they relate, must be approved by holders of at least a majority of the outstanding depositary shares. No amendment will impair the right of a holder of depositary shares to surrender the depositary receipts evidencing those depositary shares and receive the preferred stock to which they relate, except as required to comply with law. We may terminate a deposit agreement with the consent of holders of a majority of the depositary shares to which it relates. Upon termination of a deposit agreement, the depositary will make the whole or fractional shares of preferred stock to which the depositary shares issued under the deposit agreement relate available to the holders of those depositary shares. A deposit agreement will automatically terminate if:

•

all outstanding depositary shares to which it relates have been redeemed or converted; or

•

the depositary has made a final distribution to the holders of the depositary shares issued under the deposit agreement upon our liquidation, dissolution or winding up.

Miscellaneous

There will be provisions: (1) requiring the depositary to forward to holders of record of depositary shares any reports or communications from us which the depositary receives with respect to the preferred stock to which the depositary shares relate; (2) regarding compensation of the depositary; (3) regarding resignation of the depositary; (4) limiting our liability and the liability of the depositary under the deposit agreement (generally limited to failure to act in good faith, gross negligence or willful misconduct); and (5) indemnifying the depositary against certain possible liabilities.

TABLE OF CONTENTS

DESCRIPTION OF DEBT SECURITIES

We may issue debt securities, in one or more series, as either senior or subordinated debt or as senior or subordinated convertible debt. The senior debt securities will rank equally with any other unsubordinated debt that we may have and may be secured or unsecured. The subordinated debt securities will be subordinate and junior in right of payment, to the extent and in the manner described in the instrument governing the debt, to all or some portion of our senior indebtedness. Any convertible debt securities that we may issue will be convertible into or exchangeable for Class A common stock or Class B common stock, preferred stock or other securities of ours or of a third party. Conversion may be mandatory or at the holder’s option and would be at prescribed conversion rates.

The debt securities will be issued either (i) pursuant to our existing indenture, dated as of July 13, 2021, as amended, modified or supplemented, between us and Wilmington Savings Fund Society, FSB, as trustee (“existing indenture”) or (ii) pursuant to a subordinated debt indenture that we will enter into with Wilmington Savings Fund Society, FSB, as trustee (“new subordinated debt indenture”). While the terms we have summarized below will apply generally to any debt securities that we or any selling stockholder may offer under this prospectus, we will describe the particular terms of any debt securities that we or any selling stockholder may offer in more detail in a prospectus supplement (and any free writing prospectus).

We have incorporated by reference our existing indenture and will file a form of our new subordinated debt indenture as an exhibit to a prospectus supplement. We use the term “indentures” to refer collectively to our existing indenture and our new subordinated debt indenture.

The indentures, to the extent not already qualified, will be qualified under the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”).

The following summaries of the material provisions of the senior debt securities, the subordinated debt securities and the indentures, together with the additional information we may include in any applicable prospectus supplements, does not purport to be complete and is subject to, and qualified in its entirety by reference to, all of the provisions of the form of our new subordinated debt indenture to be filed as an exhibit to a prospectus supplement to this registration statement, as it may be supplemented, amended or modified from time to time, as well as our existing indenture that are incorporated by reference as exhibits to the registration statement of which this prospectus is part. You should read the applicable prospectus supplement (and any free writing prospectus that we may authorize to be provided to you) related to the series of debt securities being offered, as well as the complete indentures that contain the terms of the debt securities.

TABLE OF CONTENTS

Conversion or Exchange Rights

We will set forth in the applicable prospectus supplement or free writing prospectus the terms on which a series of debt securities may be convertible into or exchangeable for Class A common stock or Class B common stock, preferred stock or other securities of ours, including the conversion or exchange rate, as applicable, or how it will be calculated, and the applicable conversion or exchange period. We will include provisions as to whether conversion or exchange is mandatory, at the option of the holder or at our option. We may include provisions pursuant to which the number of our securities that the holders of the series of debt securities receive upon conversion or exchange would, under the circumstances described in those provisions, be subject to adjustment, or pursuant to which those holders would, under those circumstances, receive other property upon conversion or exchange, for example in the event of our merger or consolidation with another entity.

Consolidation, Merger or Sale

The terms of any securities that we or any selling stockholder may offer pursuant to this prospectus may limit our ability to merge or consolidate or otherwise sell, convey, transfer or otherwise dispose of all or substantially all of our assets, which terms would be set forth in the applicable prospectus supplement and supplemental indenture. Any successor of ours or acquiror of such assets would have to assume all of our obligations under the indentures and the debt securities, as appropriate.

If the debt securities are convertible for our other securities, the person with whom we consolidate or merge or to whom we sell all of our property would have to make provisions for the conversion of the debt securities into securities that the holders of the debt securities would have received if they had converted the debt securities before the consolidation, merger or sale.

Events of Default Under the Indenture

Unless otherwise indicated in the applicable prospectus supplement, the following are events of default under the indentures with respect to any series of debt securities that we may issue:

•

if we fail to pay interest when due and payable and our failure continues for 30 days and the time for payment has not been extended or deferred;

•

if we fail to pay the principal or premium, if any, when due and payable and the time for payment has not been extended or deferred;

•

if we fail to observe or perform any other covenant contained in the debt securities or the indentures, and our failure continues for 60 days after we receive notice from the trustee or holders of at least 25% in aggregate principal amount of the outstanding debt securities of the applicable series; and

•

if specified events of bankruptcy, insolvency or reorganization occur.

If an event of default with respect to debt securities of any series occurs and is continuing, other than an event of default specified in the last bullet point above, the trustee or the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series, by notice to us in writing, and to the trustee if notice is given by such holders, may declare the unpaid principal of, premium, if any, and accrued interest, if any, due and payable immediately. If an event of default specified in the last bullet point above occurs with respect to us, the principal amount of and accrued interest, if any, of each issue of debt securities then outstanding would be due and payable without any notice or other action on the part of the trustee or any holder.

The holders of a majority in principal amount of the outstanding debt securities of an affected series may waive any default or event of default with respect to the series and its consequences, except defaults or events of default regarding payment of principal, premium, if any, or interest, unless we have cured the default or event of default in accordance with the indenture. Any waiver shall cure the default or event of default.

Subject to the terms of the indentures, if an event of default under an indenture occurs and continues, the trustee would be under no obligation to exercise any of its rights or powers under such indenture at the

TABLE OF CONTENTS

request or direction of any of the holders of the applicable series of debt securities, unless such holders have offered the trustee indemnity satisfactory to the trustee. The holders of a majority in principal amount of the outstanding debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee, or exercising any trust or power conferred on the trustee, with respect to the debt securities of that series, provided that:

•

the direction so given by the holder is not in conflict with any law or the applicable indenture, nor would it subject the trustee to a risk of liability in respect of which the trustee has not received indemnification satisfactory to it in its sole discretion against all losses, liabilities and expenses caused by taking or not taking such action; and

•

the trustee may take any other action deemed proper by the trustee which is not inconsistent with such direction.

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

•

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

•

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

•

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

These limitations do not apply to a suit instituted by a holder of debt securities if we default in the payment of the principal, premium, if any, or interest on, the debt securities.

We will periodically file statements with the trustee regarding our compliance with specified covenants in the indentures.

Supplemental Indentures

We and the trustee may from time to time and at any time enter into an indenture or supplemental indenture without the consent of any holders for one or more of the following purposes:

•

to evidence the succession of another corporation, and the assumption by the successor corporation of our covenants, agreements and obligations under the indenture and debt securities;

•

to add to our covenants such new covenants, restrictions, conditions or provisions for the protection of the holders, and to make the occurrence, or the occurrence and continuance, of a default in any of such additional covenants, restrictions, conditions or provisions an event of default;

•

to modify, eliminate or add to any of the provisions of the indenture to such extent as necessary to effect the qualification of the indenture under the Trust Indenture Act, and to add to the indenture such other provisions as may be expressly permitted by the Trust Indenture Act, excluding however, the provisions referred to in Section 316(a)(2) of the Trust Indenture Act;

•

to cure any ambiguity or to correct or supplement any provision contained in the indenture or in any supplemental indenture which may be defective or inconsistent with other provisions;

•

to make provisions in regard to matters or questions arising under the indenture, so long such other provisions to do not adversely affect the interest of any other holder of debt securities in any material respect;

•

to secure any series of security;

•

to evidence and provide for the acceptance and appointment of a successor trustee and to add or change any provisions of the indenture as necessary to provide for or facilitate the administration of the trust by more than one trustee; and

TABLE OF CONTENTS

•

to establish the form or terms of securities of any series as permitted under the indenture, including any subordination provisions.

In addition, we and the trustee, with the consent of the holders of not less than a majority in aggregate principal of the outstanding debt securities of each series that is affected, may from time to time and at any time enter into an indenture or supplemental indenture for the purpose of adding any provisions to or changing in any manner the rights of the holders of the securities of such series and any related coupons of the indenture, provided that no such supplemental indenture shall:

•

extend the fixed maturity of any securities, or reduce the principal amount thereof or premium, if any, or reduce the rate or extend the time of payment of interest, without the extent of the holder so affected;

•

reduce the aforesaid percentage of securities, the consent of the holders of which is required for any such supplemental indenture, without the consent of all holders of outstanding series of debt securities;

•

impair the right to institute suit for the enforcement of any payment on or after the date on which it is due and payable; or

•

modify any of the above provisions.

Discharge

Each indenture will provide that we can elect to be discharged from our obligations with respect to one or more series of debt securities, except for specified obligations, including obligations to:

•

replace stolen, lost or mutilated debt securities of the series;

•

maintain paying agencies; and

•

hold monies for payment in trust.

In order to exercise our rights to be discharged, we must deposit with the trustee money or government obligations, or a combination thereof, sufficient to pay all the principal of, any premium and interest on, the debt securities of the series on the dates payments are due.

Form, Exchange and Transfer

We will issue the debt securities of each series only in fully registered form without coupons and, unless we otherwise specify in the applicable prospectus supplement or free writing prospectus, in denominations of $2,000 and any integral multiple of $1,000 in excess thereof. The indentures will provide that we may issue debt securities of a series in temporary or permanent global form and as book-entry securities that will be deposited with, or on behalf of, The Depository Trust Company or another depositary named by us and identified in a prospectus supplement or free writing prospectus with respect to that series.

At the option of the holder, subject to the terms of the indentures and the limitations applicable to global securities described in the applicable prospectus supplement or free writing prospectus, the holder of the debt securities of any series can exchange the debt securities for other debt securities of the same series, in any authorized denomination and of like tenor and aggregate principal amount.

Subject to the terms of the indentures and the limitations applicable to global securities set forth in the applicable prospectus supplement or free writing prospectus, holders of the debt securities may present the debt securities for exchange or for registration of transfer, duly endorsed or with the form of transfer endorsed thereon duly executed if so required by us or the security registrar, at the office of the security registrar or at the office of any transfer agent designated by us for this purpose. Unless otherwise provided in the debt securities that the holder presents for transfer or exchange, we will make no service charge for any registration of transfer or exchange, but we may require payment of any taxes or other governmental charges.

We will name in the applicable prospectus supplement or free writing prospectus the security registrar, and any transfer agent in addition to the security registrar that we initially designate for any debt securities.

TABLE OF CONTENTS

We may at any time designate additional transfer agents or rescind the designation of any transfer agent or approve a change in the office through which any transfer agent acts, except that we will be required to maintain a transfer agent in each place of payment for the debt securities of each series.

If we elect to redeem the debt securities of any series, we will not be required to:

•

issue, register the transfer of, or exchange any debt securities of any series being redeemed in part during a period beginning at the opening of business 15 days before the day of sending of a notice of redemption of any debt securities that may be selected for redemption and ending at the close of business on the day of such transmission; or

•

register the transfer of or exchange any debt securities so selected for redemption, in whole or in part, except the unredeemed portion of any debt securities we are redeeming in part.

Information Concerning the Trustee

The trustee, other than during the occurrence and continuance of an event of default under an indenture, undertakes to perform only those duties as are specifically set forth in the applicable indenture. Upon an event of default under an indenture, the trustee must use the same degree of care as a prudent person would exercise or use in the conduct of his or her own affairs. Subject to this provision, the trustee is under no obligation to exercise any of the powers given it by an indenture at the request of any holder of debt securities unless it is offered security and indemnity against the costs, expenses and liabilities that it might incur.

Payment and Paying Agents

Unless we otherwise indicate in the applicable prospectus supplement or free writing prospectus, we will make payment of the interest on any debt securities on any interest payment date to the person in whose name the debt securities, or one or more predecessor securities, are registered at the close of business on the regular record date for the interest.

We will pay principal of and any premium and interest on the debt securities of a particular series at the office of the paying agents designated by us, except that, unless we otherwise indicate in the applicable prospectus supplement or free writing prospectus, we may make interest payments by check which we will mail to the holder or by wire transfer to certain holders. Unless we otherwise indicate in a prospectus supplement or free writing prospectus, we will designate an office or agency of the trustee in the contiguous United States as our sole paying agent for payments with respect to debt securities of each series. We will name in the applicable prospectus supplement or free writing prospectus any other paying agents that we initially designate for the debt securities of a particular series. We will maintain a paying agent in each place of payment for the debt securities of a particular series.

All money we pay to a paying agent or the trustee for the payment of the principal of or any premium or interest on any debt securities which remains unclaimed at the end of two years after such principal, premium or interest has become due and payable will be repaid to us, and the holder of the debt security thereafter may look only to us for payment thereof.

Governing Law

The indentures and the debt securities will be governed by and construed in accordance with the laws of the State of New York, except to the extent that the Trust Indenture Act is applicable.

Subordination of Subordinated Debt Securities

The subordinated debt securities will be subordinate and junior in priority of payment to certain of our other indebtedness to the extent described in a prospectus supplement or free writing prospectus. Our new subordinated debt indenture in the form to be filed as an exhibit to a prospectus supplement, and our existing indenture, do not limit the amount of indebtedness which we may incur, including senior indebtedness or subordinated indebtedness, and do not limit us from issuing any other debt, including secured debt or unsecured debt.

INFORMATION NOT REQUIRED IN THE PROSPECTUS

Item 14. Other Expenses of Issuance and Distribution.

The following table shows the fees and expenses payable by us in connection with the sale and distribution of the securities being registered hereby. All amounts except the SEC registration fee are estimated.

SEC registration fee	$	*
Legal fees and expenses (other than Blue Sky)		+
Blue Sky fees and expenses (including counsel fees)		+
Listing fee		+
Accounting fees and expenses		+
Printing fees		+
Trustee and registrar’s fees and expenses		+
Rating Agency fees		+
Miscellaneous		+
Total	$	+

In accordance with Rules 456(b) and 457(r) of the Securities Act, we are deferring payment of the registration fee for the securities offered.

The amount of securities and number of offerings are indeterminable and the expenses cannot be estimated at this time. An estimate of the aggregate expenses in connection with the sale and distribution of securities being offered will be included in any applicable prospectus supplement.

Item 15. Indemnification of Directors and Officers.

Section 145 of the DGCL provides that a corporation may indemnify any person who was or is a party, or is threatened to be made a party, to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation by reason of the fact that he 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 him in connection with such action, suit or proceeding if he acted in good faith and in a manner he 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 conduct was unlawful. A similar standard is applicable in the case of derivative actions (i.e., actions by or in the right of the corporation), except that indemnification extends only to expenses, including attorneys’ fees, incurred in connection with the defense or settlement of such action and the statute requires court approval before there can be any indemnification where the person seeking indemnification has been found liable to the corporation.

Our certificate of incorporation and our bylaws contain provisions that limit the liability of our directors and officers for monetary damages to the fullest extent permitted by the DGCL. Consequently, our directors are not personally liable to us or our stockholders for monetary damages for breach of fiduciary duty as a director, except liability:

•

for any breach of the director’s duty of loyalty to our company or our stockholders;

•

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

•

under Section 174 of the DGCL regarding unlawful dividends and stock purchases; or

•

for any transaction from which the director derived an improper personal benefit.

II-1

TABLE OF CONTENTS

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

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

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

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling us pursuant to the foregoing provisions, we have been informed that in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment of expenses incurred or paid by a director, officer or controlling person in a successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, we will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to the 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.

Item 16. Exhibits.

The Exhibits to this registration statement are listed on the exhibit index, which appears elsewhere herein and is incorporated herein by reference.

Item 17. Undertakings.

(a) The undersigned registrant hereby undertakes:

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

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

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

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; provided, however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to

TABLE OF CONTENTS

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 of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

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

(i) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(ii) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(5) That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

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

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

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

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

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee

benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the 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.

(d) 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 (“Act”) in accordance with the rules and regulations prescribed by the SEC under Section 305(b)(2) of the Act.
