ABOUT THIS PROSPECTUS SUPPLEMENT

This prospectus supplement and the accompanying prospectus are part of a registration statement that we filed with the the U.S. Securities and Exchange Commission, or the Commission, utilizing a "shelf" registration process. This document is in two parts. The first part is this prospectus supplement, which describes the specific terms of this offering and the securities offered hereby and also adds to and updates information contained in the accompanying prospectus and the documents incorporated by reference into this prospectus supplement and the accompanying prospectus. The second part, the accompanying base prospectus, gives more general information and disclosure about the securities we may offer from time to time, some of which does not apply to this offering of common shares. When we refer to the prospectus, we are referring to both parts combined, and when we refer to the accompanying prospectus, we are referring to the base prospectus.

If the description of this offering varies between this prospectus supplement and the accompanying prospectus, you should rely on the information in the prospectus supplement. This prospectus supplement, the accompanying prospectus and the documents incorporated into each by reference include important information about us and the common shares being offered and other information you should know before investing. You should read this prospectus supplement and the accompanying prospectus together with the additional information described under the heading, "Where You Can Find Additional Information" in this prospectus supplement and the accompanying prospectus before investing in our common shares.

Any statement made in the prospectus or in a document incorporated or deemed to be incorporated by reference into the prospectus will be deemed to be modified or superseded for purposes of the prospectus to the extent that a statement contained in the prospectus supplement or in any other subsequently filed document that is also incorporated by reference into the prospectus modifies or supersedes that statement. Any statement so modified or superseded will not be deemed, except as so modified or superseded, to constitute a part of the prospectus.

You should rely only on the information contained in or incorporated by reference in this prospectus supplement, the accompanying prospectus and any free writing prospectus prepared by or on behalf of us or to which we have referred you . We have not, and the sales agent has not, authorized anyone to provide you with information that is different. If anyone provides you with different or inconsistent information, you should not rely on it. We are offering to sell our common shares only in jurisdictions where offers and sales are permitted. The information contained in or incorporated by reference in the prospectus is accurate only as of the date such information was issued, regardless of the time of delivery of the prospectus or any sale of our common shares.

Unless otherwise indicated, all references to "$" and "dollars" in this prospectus supplement are to United States dollars, and financial information presented in this prospectus supplement is derived from financial statements that are incorporated by reference and were prepared in accordance with accounting principles generally accepted in the United States. We have a fiscal year end of December 31.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This prospectus supplement and the documents incorporated by reference contain certain forward-looking statements made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Forward-looking statements include, but are not limited to, statements regarding our or our management's expectations, hopes, beliefs, intentions or strategies regarding the future and other statements that are other than statements of historical fact. In addition, any statements that refer to projections, forecasts or other characterizations of future events or circumstances, including any underlying assumptions, are forward-looking statements. The words "anticipate," "believe," "continue," "could," "estimate," "expect," "intend," "may," "might," "plan," "possible," "potential," "predict," "project," "should," "would" and similar expressions may identify forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking.

The forward-looking statements in this prospectus supplement and the documents incorporated by reference are based upon various assumptions, many of which are based, in turn, upon further assumptions, including without limitation, management's examination of historical operating trends, data contained in our records and other data available from third parties. Although we believe that these assumptions were reasonable when made, because these assumptions are inherently subject to significant uncertainties and contingencies which are difficult or impossible to predict and are beyond our control, we cannot assure you that we will achieve or accomplish these expectations, beliefs or projections. As a result, you are cautioned not to rely on any forward-looking statements.

In addition to these important factors and matters discussed elsewhere herein and in the documents incorporated by reference herein, important factors that, in our view, could cause actual results to differ materially from those discussed in the forward-looking statements include among other things:

changes in shipping industry trends, including charter rates, vessel values and factors affecting vessel supply and demand;

S-i

changes in seaborne and other transportation patterns;

changes in the supply of or demand for drybulk commodities, including drybulk commodities carried by sea, generally or in particular regions;

changes in the number of newbuildings under construction in the drybulk shipping industry;

changes in the useful lives and the value of our vessels and the related impact on our compliance with loan covenants;

the aging of our fleet and increases in operating costs;

our ability to achieve successful utilization of our expanded fleet;

changes in our ability to complete acquisitions or dispositions;

changes to our financial condition and liquidity, including our ability to pay amounts that we owe and obtain additional financing to fund capital expenditures, acquisitions and other general corporate activities;

risks related to our business strategy, areas of possible expansion or expected capital spending or operating expenses;

changes in the availability of crew, number of off-hire days, classification survey requirements and insurance costs for the vessels in our fleet;

changes in our ability to leverage the relationships and reputation in the drybulk shipping industry of V.Ships Limited, or V.Ships, and Fidelity Marine Inc., or Fidelity;

changes in our relationships with our contract counterparties, including the failure of any of our contract counterparties to comply with their agreements with us;

loss of our customers, charters or vessels;

damage to our vessels;

potential liability from future litigation and incidents involving our vessels;

our future operating or financial results;

our ability to continue as a going concern;

acts of terrorism and other hostilities;

changes in global and regional economic and political conditions;

changes in governmental rules and regulations or actions taken by regulatory authorities, particularly with respect to the drybulk shipping industry; and

other factors listed from time to time in registration statements, reports or other materials that we have filed with or furnished to the Commission including our most recent annual report on Form 20-F, which is incorporated by reference into this prospectus.

These factors could cause actual results or developments to differ materially from those expressed in any of our forward-looking statements. Other unknown or unpredictable factors also could materially harm our results. Consequently, there can be no assurance that actual results or developments anticipated by us will be realized or, even if substantially realized, that they will have the expected consequences to, or effects on, us. Given these uncertainties, prospective investors are cautioned not to place undue reliance on such forward-looking statements.

We undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law. If one or more forward-looking statements are updated, no inference should be drawn that additional updates will be made with respect to those or other forward-looking statements.

Overview

We are an international shipping company specializing in the worldwide seaborne transportation of drybulk commodities. In March 2014, we completed a financial restructuring. As of February 3, 2017, we owned a fleet of ten drybulk carriers, comprised of eight Capesize vessels and two Supramax vessels, with a combined cargo-carrying capacity of approximately 1,503,369 dwt and an average age of approximately 8.1 years. Capesize vessels range in size between 100,000 to 220,000 dwt. Supramax vessels range in size between 40,000 to 65,000 dwt.

We believe we have established a reputation in the international drybulk shipping industry for operating and maintaining vessels with high standards of performance, reliability and safety. We have assembled a management team comprised of executives who we believe have extensive experience operating large and diversified fleets, and who have strong ties to a number of international charterers.

Our Fleet

As of February 3, 2017, we owned a fleet of ten drybulk carriers, comprised of eight Capesize vessels and two Supramax vessels, with a combined cargo-carrying capacity of approximately 1,503,369 dwt and an average age of approximately 8.1 years.

The following table lists the vessels in our fleet as of February 3, 2017:

Recent Developments

During November and December 2016, we took delivery of two vessels, the Lordship , a 178,838 dwt Capesize drybulk vessel, and the Knightship , a 178,978 dwt Capesize drybulk vessel, both of which were built in 2010 by Hyundai Heavy Industries in South Korea. The vessels were acquired from an unaffiliated third party for an aggregate purchase price of $41.5 million.

S-1

In December 2016, we completed a public offering of 11,300,000 of our common shares and class A warrants to purchase 11,500,000 common shares, or the Offering, which included the exercise of an over-allotment option. In connection with the Offering, we issued to Maxim Group LLC Representative's Warrants to purchase 565,000 of our common shares. We received net proceeds of $14.9 million in connection with the consummation of the Offering. The class A warrants and Representative's Warrants have the following terms:

Class A Warrants

Duration and Exercise Price

Each class A warrant is immediately exercisable for one common share at an exercise price of $2.00 per share. The class A warrants expire in December 2021. The exercise price and number of common shares issuable upon exercise is subject to appropriate adjustment in the event of share dividends, share splits, reverse share splits, reorganizations or similar events affecting our common shares. The exercise price and number of common shares issuable upon exercise is also subject to appropriate adjustment in the event of extraordinary dividends and other distributions, which does not include regularly or other periodic dividends that we may initiate in the future.

Exercisability

The class A warrant are exercisable, at the option of each holder, in whole or in part, by delivering to us a duly executed exercise notice accompanied by payment in full for the number of common shares purchased upon such exercise (except in the case of a cashless exercise as discussed below). A holder (together with its affiliates and any persons acting together with the holder as a group) may not exercise any portion of a class A warrant to the extent that the holder would own more than 4.99% of the outstanding common shares after exercise, except that upon at least 61 days' prior notice from the holder to us, the holder may increase the amount of ownership of outstanding shares after exercising the holder's class A warrants, as applicable, up to 9.99% of the number of our common shares outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the class A warrants. No fractional common shares will be issued in connection with the exercise of a class A warrant. In lieu of fractional shares, we will round down to the next whole share. We and the warrant agent may deem and treat the person in whose name the class A warrants are registered in the applicable warrant register as the absolute owner of such class A warrants for the purpose of any exercise.

Cashless Exercise

If, at the time a holder exercises its class A warrants, there is no effective registration statement registering, or the prospectus contained therein is not available for an issuance of, the shares underlying the class A warrants, then in lieu of making the cash payment otherwise contemplated to be made to us upon such exercise in payment of the aggregate exercise price, the holder may elect instead to receive upon such exercise (either in whole or in part) the net number of common shares determined according to a formula set forth in the class A warrants.

Fundamental Transactions

In the event of any fundamental transaction, as described in the class A warrants, and generally including any merger with or into another entity, sale of all or substantially all of our assets, tender offer or exchange offer, or reclassification of our common shares, then upon any subsequent exercise of a class A warrant, the holder will have the right to receive as alternative consideration, for each share of our common shares that would have been issuable upon such exercise immediately prior to the occurrence of such fundamental transaction, the number of common shares of the successor or acquiring corporation or of our company, if it is the surviving corporation, and any additional consideration receivable upon or as a result of such transaction by a holder of the number of shares of our common shares for which the class A warrants are exercisable immediately prior to such event. In addition, in the event of a fundamental transaction we or any successor entity will be required to purchase, at a holder's option, exercisable at any time concurrently with or within thirty (30) days after the consummation of the fundamental transaction, such holder's class A warrants for cash in an amount equal to the value of the unexercised portion of such holder's class A warrants, determined in accordance with the Black-Scholes option pricing model as specified in the class A warrants.

S-2

Callability

The class A warrants are callable by us beginning January 2018 under certain conditions, including the volume weighted average price of the common shares exceeding $7.00 for a period of 10 consecutive trading days, or the Measurement Period. We may, within one trading day of the end of such Measurement Period, call for cancellation of all or any portion of the outstanding and unexercised class A warrants for consideration equal to $0.0001 per common share issuable upon exercise of the class A warrants.

Transferability

Subject to applicable laws and the restriction on transfer set forth in the class A warrants, the class A warrants may be transferred at the option of the holder upon surrender of the class A warrants to us together with the appropriate instruments of transfer.

Listing

The class A warrants are listed on the Nasdaq Capital Market under the symbol "SHIPW".

Right as a Shareholder

Except as otherwise provided in the class A warrants or by virtue of such holder's ownership of our common shares, the holders of the class A warrants do not have the rights or privileges of holders of our common shares, including any voting rights, until the first trading day after the aggregate exercise price has been paid to us in connection with any exercise of the class A warrants.

Waivers and Amendments

Subject to certain exceptions, any term of the class A warrants may be amended or waived with our written consent and the written consent of the holders of at least a majority of the then-outstanding class A warrants.

Representative's Warrants

The Representative's Warrants will be non-exercisable until June 6, 2017 , have an exercise price equal to $1.875 per share, provide for cashless exercise in certain circumstances and shall terminate December 7, 2019, and otherwise have the same terms as the class A warrants except that (1) they will not be callable by us, (2) if a registration statement is not available to use to sell the underlying shares, until December 7, 2023, they provide for unlimited "piggyback" registration rights with respect to the underlying shares, and, (3) if a registration statement is not available to use to sell the underlying shares, until December 7, 2021, they provide for one demand registration of the sale of the underlying common shares at our expense and an additional demand registration at the warrant holders' expense. Such Representative's Warrant are subject to FINRA Rule 5110(g)(1) in that, except as otherwise permitted by FINRA rules, until June 6, 2017, the Representative's Warrant shall not be (A) sold, transferred, assigned, pledged, or hypothecated, or (B) the subject of any hedging, short sale, derivative, put, or call transaction that would result in the effective economic disposition of the securities by any person except as permitted by FINRA Rule 5110(g)(2).

S-4

RISK FACTORS

An investment in our common shares involves a high degree of risk and uncertainty. You should carefully consider the risks described below and discussed under the caption "Risk Factors" in our Annual Report on Form 20-F for the year ended December 31, 2015, incorporated by reference herein, as well as the other information included in this prospectus supplement and the accompanying prospectus before deciding to invest in our common shares. If any of the risks occur, our business, financial conditions or results of operations may be materially and adversely affected. In that event, the trading price of our common shares could decline, and you could lose all or part of your investment.

Risks Related to our Common Shares and this Offering

The market price of our common shares has been and may in the future be subject to significant fluctuations. Further, there is no guarantee of a continuing public market for you to resell our common shares.

Our common shares commenced trading on the Nasdaq Global Market on October 15, 2008. Since December 21, 2012, our common shares have traded on the Nasdaq Capital Market. We cannot assure you that an active and liquid public market for our common shares will continue.

The market price of our common shares has been and may in the future be subject to significant fluctuations as a result of many factors, some of which are beyond our control. Among the factors that have in the past and could in the future affect our stock price are:

quarterly variations in our results of operations;

changes in market valuations of similar companies and stock market price and volume fluctuations generally;

changes in earnings estimates or the publication of research reports by analysts;

speculation in the press or investment community about our business or the shipping industry generally;

strategic actions by us or our competitors such as acquisitions or restructurings;

the thin trading market for our common shares, which makes it somewhat illiquid;

regulatory developments;

additions or departures of key personnel;

general market conditions; and

domestic and international economic, market and currency factors unrelated to our performance.

The stock markets in general, and the markets for drybulk shipping and shipping stocks in particular, have experienced extreme volatility that has sometimes been unrelated to the operating performance of individual companies. These broad market fluctuations may adversely affect the trading price of our common shares.

Additionally, there is no guarantee of a continuing public market for you to resell our common shares. Our common shares now trade on the Nasdaq Capital Market. We cannot assure you that an active and liquid public market for our common shares will continue.

We may issue additional common shares or other equity securities without stockholder approval, which would dilute our existing stockholder's ownership interests and may depress the market price of our common shares.

We may issue additional common shares or other equity securities of equal or senior rank in the future without shareholder approval in connection with, among other things, future vessel acquisitions, the repayment of outstanding indebtedness, and the conversion of convertible financial instruments.

S-5

Our issuance of additional common shares or other equity securities of equal or senior rank in these situations would have the following effects:

our existing shareholders' proportionate ownership interest in us would decrease;

the proportionate amount of cash available for dividends payable on our common shares could decrease;

the relative voting strength of each previously outstanding common share could be diminished; and

the market price of our common shares could decline.

In addition, we may issue additional common shares upon any conversion of our outstanding convertible promissory notes issued to an entity affiliated with our principal shareholder, Jelco Delta Holding Corp., or Jelco, or upon exercise of our outstanding class A warrants or the Representative's Warrants issued to Maxim Group LLC in connection with the Offering in December 2016.

As of February 3, 2017, Jelco had the right to acquire 4,222,223 common shares upon exercise of a conversion option pursuant to the convertible promissory note dated March 12, 2015, issued by the Company to Jelco, and 23,516,667 common shares upon exercise of a conversion option pursuant to the convertible promissory note dated September 7, 2015, as amended, issued by the Company to Jelco. Under each of the convertible promissory notes, Jelco may, at its option, convert the principal amount under each note at any time into common shares at a conversion price of $0.90 per share. Our issuance of additional common shares in such instance would cause the proportionate ownership interest in us of our existing shareholders, other than Jelco, to decrease; the relative voting strength of each previously outstanding common share held by our existing shareholders to decrease; and the market price of our common shares could decline.

As of February 3, 2017, we had 11,500,000 class A warrants outstanding to purchase an aggregate of 11,500,000 common shares and two Representative's Warrants outstanding to purchase an aggregate of 565,000 common shares. Each class A warrant is exercisable for one common share at an exercise price of $2.00 per share and expires in December 2021. The Representative's Warrants have an exercise price equal to $1.875 per common share and expire in December 2019. Our issuance of additional common shares upon the exercise of the class A warrants or Representative's Warrants would cause the proportionate ownership interest in us of our existing shareholders, other than the exercising warrant holders, to decrease; the relative voting strength of each previously outstanding common share held by our existing shareholders to decrease; and the market price of our common shares could decline.

The actual number of shares we will issue under the equity distribution agreement, at any one time or in total, is uncertain.

Subject to certain limitations in the equity distribution agreement and compliance with applicable law, we have the discretion to deliver placement notices to Maxim Group LLC at any time throughout the term of the equity distribution agreement. The number of shares that are sold by Maxim Group LLC after delivering a placement notice will fluctuate based on the market price of the common shares during the sales period and limits we set with Maxim Group LLC.

Investors may experience significant dilution as a result of this offering.

Assuming we sell all of the 17,391,304 common shares offered pursuant to this prospectus supplement (assuming a sale price of $1.15 per share, which was the closing price of our common shares on February 2, 2017), we will have approximately 51,463,514 common shares outstanding, which represents in the aggregate an increase of approximately 51% in our currently issued and outstanding common shares. Because the sales of the shares offered hereby will be made directly into the market or in negotiated transactions, the prices at which we sell these shares will vary and these variations may be significant. If we sell all or a substantial portion of the total shares offered pursuant to this prospectus supplement, the proportionate ownership interest in us of our existing shareholders will decrease; the relative voting strength of each previously outstanding common share held by our existing shareholders will decrease and the market price of our common shares could decline. If an investor purchases shares offered hereby and following such purchase we sell shares at prices significantly below the price at which the investor purchased its shares, the investor's proportionate ownership interest in us would decrease; the relative voting strength of each of its common shares would decrease and the market value of its common shares would decline.

S-6

We will have broad discretion in the use of the net proceeds from this offering and may not use them effectively.

We currently intend to use the net proceeds of this offering for general corporate purposes, which may include debt repayments and vessels acquisitions, as described in the section of this prospectus supplement entitled "Use of Proceeds". We will have broad discretion in the application of the net proceeds for general corporate purposes and investors will be relying on the judgment of our management regarding the application of the proceeds of this offering. The amounts and timing of our use of the net proceeds from this offering will depend on a number of factors. Depending on the outcome of these activities and other unforeseen events, our plans and priorities may change and we may apply the net proceeds of this offering in different manners than we currently anticipate. The failure by our management to apply these funds effectively could harm our business, financial condition and results of operations.

The declaration and payment of dividends is subject to the discretion of our board of directors and will depend on a number of factors. Our board of directors may not declare dividends in the future.

The declaration, timing and amount of any dividends is subject to the discretion of our board of directors and will be dependent upon our earnings, financial condition, market prospects, capital expenditure requirements, investment opportunities, restrictions in our loan agreements, the provisions of Marshall Islands law affecting the payment of dividends to shareholders, overall market conditions and other factors. Our board of directors may not declare dividends in the future.

Marshall Islands law generally prohibits the payment of dividends if the company is insolvent or would be rendered insolvent upon payment of such dividend, and dividends may be declared and paid out of our operating surplus. Dividends may also be declared or paid out of net profits for the fiscal year in which the dividend is declared and for the preceding fiscal year. We may be unable to pay dividends in the anticipated amounts or at all.

Jelco and Comet Shipholding Inc., are able to control the outcome of all matters requiring a shareholder vote, and their interests could conflict with the interests of our other shareholders.

Based on documents publicly filed with the Commission, Jelco and Comet Shipholding Inc., or Comet, both companies affiliated with our principal shareholder, or our Sponsor, collectively own approximately 16,763,774, or approximately 49.2%, of our outstanding common shares as of February 3, 2017. Jelco may also acquire up to 27,738,890 additional common shares upon conversion of the convertible promissory notes issued to it by the Company, in which case our Sponsor would own approximately 72.0% of our outstanding common shares. As a result, our Sponsor will generally be able to control the outcome of all matters requiring a shareholder vote. This concentration of ownership may delay, deter or prevent acts that would be favored by our other shareholders or deprive shareholders of an opportunity to receive a premium for their shares as part of a sale of our business, and it is possible that the interests of our Sponsor may in some cases conflict with our interests and the interests of our other holders of shares. For example, conflicts of interest may arise between us, on one hand, and our Sponsor or affiliated entities, on the other hand, which may result in the transactions on terms not determined by market forces. Any such conflicts of interest could adversely affect our business, financial condition and results of operations, and the trading price of our common shares. In addition, this concentration of share ownership may adversely affect the trading price of our shares because investors may perceive disadvantages in owning shares in a company with controlling shareholders.

Anti-takeover provisions in our amended and restated articles of incorporation and by-laws could make it difficult for shareholders to replace or remove our current board of directors or could have the effect of discouraging, delaying or preventing a merger or acquisition, which could adversely affect the market price of our common shares.

Several provisions of our amended and restated articles of incorporation and by-laws could make it difficult for shareholders to change the composition of our board of directors in any one year, preventing them from changing the composition of our management. In addition, the same provisions may discourage, delay or prevent a merger or acquisition that shareholders may consider favorable.

These provisions:

authorize our board of directors to issue "blank check" preferred stock without shareholder approval;

provide for a classified board of directors with staggered, three-year terms;

require a super-majority vote in order to amend the provisions regarding our classified board of directors with staggered, three-year terms;

permit the removal of any director from office at any time, with or without cause, at the request of the shareholder group entitled to designate such director; and

prevent our board of directors from dissolving the shipping committee or altering the duties or composition of the shipping committee without an affirmative vote of not less than 80% of the board of directors.

S-7

These anti-takeover provisions could substantially impede the ability of shareholders to benefit from a change in control and, as a result, may adversely affect the market price of our common shares and your ability to realize any potential change of control premium.

Issuance of preferred stock may adversely affect the voting power of our shareholders and have the effect of discouraging, delaying or preventing a merger or acquisition, which could adversely affect the market price of our common shares.

Our amended and restated articles of incorporation currently authorize our board of directors to issue preferred shares in one or more series and to determine the rights, preferences, privileges and restrictions, with respect to, among other things, dividends, conversion, voting, redemption, liquidation and the number of shares constituting any series without shareholders' approval. If our board of directors determines to issue preferred shares, such issuance may discourage, delay or prevent a merger or acquisition that shareholders may consider favorable. The issuance of preferred shares with voting and conversion rights may also adversely affect the voting power of the holders of common shares. This could substantially impede the ability of public shareholders to benefit from a change in control and, as a result, may adversely affect the market price of our common shares and your ability to realize any potential change of control premium.

We are incorporated in the Republic of the Marshall Islands, which does not have a well-developed body of corporate law, which may negatively affect the ability of shareholders to protect their interests.

Our corporate affairs are governed by our amended and restated articles of incorporation, our amended and restated by-laws and by the Marshall Islands Business Corporations Act, or the BCA. The provisions of the BCA resemble provisions of the corporation laws of a number of states in the United States. However, there have been few judicial cases in the Republic of the Marshall Islands interpreting the BCA. The rights and fiduciary responsibilities of directors under the laws of the Republic of the Marshall Islands are not as clearly established as the rights and fiduciary responsibilities of directors under statutes or judicial precedent in existence in certain U.S. jurisdictions. Shareholder rights may differ as well. While the BCA does specifically incorporate the non-statutory law, or judicial case law, of the State of Delaware and other states with substantially similar legislative provisions, shareholders may have more difficulty in protecting their interests in the face of actions by the management, directors or controlling shareholders than would shareholders of a corporation incorporated in a U.S. jurisdiction.

USE OF PROCEEDS

We intend to use the net proceeds of this offering, after deducting the sale agent's commissions and our estimated offering expenses, for general corporate purposes, which may include debt repayments and vessel acquisitions. However, we do not currently have definitive plans for any debt repayments nor have we identified any potential vessel acquisitions, and we can provide no assurance that we will use the proceeds of this offering to complete any debt repayment or complete the acquisition of any vessels that we are able to identify.

TAXATION

The following is a summary of the material U.S. federal income tax and Marshall Islands tax consequences of the ownership and disposition of our common stock as well as the material U.S. federal and Marshall Islands income tax consequences applicable to us and our operations. The discussion below of the U.S. federal income tax consequences to "U.S. Holders" will apply to a beneficial owner of our common stock that is treated for U.S. federal income tax purposes as:

an individual citizen or resident of the United States;

a corporation (or other entity treated as a corporation for U.S. federal income tax purposes) that is created or organized (or treated as created or organized) in or under the laws of the United States, any state thereof or the District of Columbia; or

an estate whose income is includible in gross income for U.S. federal income tax purposes regardless of its source; or a trust if (i) a U.S. court can exercise primary supervision over the trust's administration and one or more U.S. persons are authorized to control all substantial decisions of the trust, or (ii) it has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person.

If you are not described as a U.S. Holder and are not an entity treated as a partnership or other pass-through entity for U.S. federal income tax purposes, you will be considered a "Non-U.S. Holder." The U.S. federal income tax consequences applicable to Non-U.S. Holders is described below under the heading "United States Federal Income Taxation of Non-U.S. Holders."

This discussion does not consider the tax treatment of partnerships or other pass-through entities or persons who hold our common stock through such entities. If a partnership (or other entity classified as a partnership for U.S. federal income tax purposes) is the beneficial owner of our common stock, the U.S. federal income tax treatment of a partner in the partnership generally will depend on the status of the partner and the activities of the partnership.

This summary is based on the U.S. Internal Revenue Code of 1986. as amended, or the Code, its legislative history, Treasury Regulations promulgated thereunder, published rulings and court decisions, all as currently in effect. These authorities are subject to change, possibly on a retroactive basis.

This summary does not address all aspects of U.S. federal income taxation that may be relevant to any particular holder based on such holder's individual circumstances. In particular, this discussion considers only holders that will own and hold our common stock as capital assets within the meaning of Section 1221 of the Code and does not address the potential application of the alternative minimum tax or the U.S. federal income tax consequences to holders that are subject to special rules, including:

financial institutions or "financial services entities";

broker-dealers;

taxpayers who have elected mark-to-market accounting;

tax-exempt entities;

governments or agencies or instrumentalities thereof;

insurance companies;

regulated investment companies;

real estate investment trusts;

certain expatriates or former long-term residents of the United States;

persons that actually or constructively own 10% or more of our voting shares;

persons that hold our warrants;

S-11

persons that hold our common stock or warrants as part of a straddle, constructive sale, hedging, conversion or other integrated transaction; or

persons whose functional currency is not the U.S. dollar.

This summary does not address any aspect of U.S. federal non-income tax laws, such as gift or estate tax laws, or state, local or non-U.S. tax laws.

We have not sought, nor will we seek, a ruling from the Internal Revenue Service, or the IRS, as to any U.S. federal income tax consequence described herein. The IRS may disagree with the description herein, and its determination may be upheld by a court.

Because of the complexity of the tax laws and because the tax consequences to any particular holder of our common stock may be affected by matters not discussed herein, each such holder is urged to consult with its tax advisor with respect to the specific tax consequences of the ownership and disposition of our common stock, including the applicability and effect of state, local and non-U.S. tax laws, as well as U.S. federal tax laws.

United States Federal Income Tax Consequences

Taxation of Operating Income: In General

Unless exempt from United States federal income taxation under the rules discussed below, a foreign corporation is subject to United States federal income taxation in respect of any income that is derived from the use of vessels, from the hiring or leasing of vessels for use on a time, voyage or bareboat charter basis, from the participation in a shipping pool, partnership, strategic alliance, joint operating agreement, code sharing arrangements or other joint venture it directly or indirectly owns or participates in that generates such income, or from the performance of services directly related to those uses, which we refer to as "shipping income," to the extent that the shipping income is derived from sources within the United States. For these purposes, 50% of the gross shipping income that is attributable to transportation that begins or ends, but that does not both begin and end, in the United States, exclusive of certain U.S. territories and possessions, constitutes income from sources within the United States, which we refer to as "U.S. source gross shipping income."

Shipping income attributable to transportation that both begins and ends in the United States is considered to be 100% from sources within the United States. We are prohibited by law from engaging in transportation that produces income considered to be 100% from sources within the United States.

Shipping income attributable to transportation exclusively between non-U.S. ports will be considered to be 100% derived from sources outside the United States. Shipping income derived from sources outside the United States will not be subject to any United States federal income tax.

For our 2016 taxable year, we were subject to a 4% U.S. federal income tax imposed without allowance for deductions for such taxable year, as described in " – Taxation in the Absence of Exemption," because we failed to qualify for exemption from tax under Section 883 of the Code, the requirements of which are described in detail below. Some of our charterparties contain clauses that permit us to seek reimbursement from charterers of any U.S. tax paid. We have yet to seek reimbursement, so we may not be successful in this regard.

For future taxable years, we may continue to be subject to the 4% U.S. federal income tax or we may be exempt from the tax under Section 883 of the Code.

Exemption of Operating Income from United States Federal Income Taxation

Under Section 883 of the Code and the regulations thereunder, we will be exempt from United States federal income taxation on our U.S.-source shipping income if:

we are organized in a foreign country (our "country of organization") that grants an "equivalent exemption" to corporations organized in the United States; and

either

more than 50% of the value of our stock is owned, directly or indirectly, by "qualified shareholders," that are persons (i) who are "residents" of our country of organization or of another foreign country that grants an "equivalent exemption" to corporations organized in the United States, and (ii) we satisfy certain substantiation requirements, which we refer to as the "50% Ownership Test;" or

our stock is "primarily" and "regularly" traded on one or more established securities markets in our country of organization, in another country that grants an "equivalent exemption" to United States corporations, or in the United States, which we refer to as the "Publicly-Traded Test."

S-12

The jurisdictions where we and our ship-owning subsidiaries are incorporated grant "equivalent exemptions" to United States corporations. Therefore, we will be exempt from United States federal income taxation with respect to our U.S. source shipping income if we satisfy either the 50% Ownership Test or the Publicly-Traded Test.

50% Ownership Test

Under the regulations, a foreign corporation will satisfy the 50% Ownership Test for a taxable year if (i) for at least half of the number of days in the taxable year, more than 50% of the value of its stock is owned, directly or constructively through the application of certain attribution rules prescribed by the regulations, by one or more shareholders who are residents of foreign countries that grant "equivalent exemption" to corporations organized in the United States and (ii) the foreign corporation satisfies certain substantiation and reporting requirements with respect to such shareholders.

These substantiation requirements are onerous and therefore there can be no assurance that we would be able to satisfy them. Even if we were not able to satisfy the 50% Ownership Test for a taxable year, we may nonetheless qualify for exemption from tax under Section 883 if we are able to satisfy the Publicly-Traded Test, which is described below.

Publicly-Traded Test

The regulations provide that the stock of a foreign corporation will be considered to be "primarily traded" on an established securities market in a country if the number of shares of each class of stock that is traded during the taxable year on all established securities markets in that country exceeds the number of shares in each such class that is traded during that year on established securities markets in any other single country.

Under the regulations, the stock of a foreign corporation will be considered "regularly traded" if one or more classes of its stock representing 50% or more of its outstanding shares, by total combined voting power of all classes of stock entitled to vote and by total combined value of all classes of stock, are listed on one or more established securities markets (such as NASDAQ Capital Market), which we refer to as the "listing threshold."

The regulations further require that with respect to each class of stock relied upon to meet the listing requirement: (i) such class of the stock is traded on the market, other than in minimal quantities, on at least sixty (60) days during the taxable year or one-sixth (1/6) of the days in a short taxable year; and (ii) the aggregate number of shares of such class of stock traded on such market is at least 10% of the average number of shares of such class of stock outstanding during such year or as appropriately adjusted in the case of a short taxable year. Even if a foreign corporation do not satisfy both tests, the regulations provide that the trading frequency and trading volume tests will be deemed satisfied by a class of stock if such class of stock is traded on an established market in the United States and such class of stock is regularly quoted by dealers making a market in such stock.

Notwithstanding the foregoing, the regulations provide, in pertinent part, that a class of stock will not be considered to be "regularly traded" on an established securities market for any taxable year in which 50% or more of the vote and value of the outstanding shares of such class of stock are owned, actually or constructively under specified attribution rules, on more than half the days during the taxable year by persons who each own directly or indirectly 5% or more of the vote and value of such class of stock, who we refer to as "5% Shareholders." We refer to this restriction in the regulations as the "Closely-Held Rule."

For purposes of being able to determine our 5% Shareholders, the regulations permit a foreign corporation to rely on Schedule 13G and Schedule 13D filings with the Securities and Exchange Commission. The regulations further provide that an investment company that is registered under the Investment Company Act of 1940, as amended, will not be treated as a 5% Shareholder for such purposes.

The Closely-Held Rule will not disqualify a foreign corporation, however, if it can establish or substantiate that qualified shareholders own, actually or constructively under specified attribution rules, sufficient shares in the closely-held block of stock to preclude the shares in the closely-held block that are owned by non-qualified 5% Shareholders from representing 50% or more of the value of such class of stock for more than half of the days during the tax year. These substantiation requirements are onerous and consequently there can be no assurance that we would be able to satisfy them.

Due to the factual nature of the issues involved, there can be no assurance that we or any of our subsidiaries will qualify for the benefits of Section 883 of the Code for our 2017 or subsequent taxable year.

S-13

Taxation in Absence of Exemption

To the extent the benefits of Section 883 are unavailable, our U.S. source gross shipping income, to the extent not considered to be "effectively connected" with the conduct of a U.S. trade or business, as described below, would be subject to a 4% tax imposed by Section 887 of the Code on a gross basis, without the benefit of deductions, otherwise referred to as the "4% Tax." Since under the sourcing rules described above, no more than 50% of our shipping income would be treated as being derived from U.S. sources, the maximum effective rate of U.S. federal income tax on our shipping income would never exceed 2% under the 4% Tax.

To the extent the benefits of the Section 883 exemption are unavailable and our U.S. source gross shipping income is considered to be "effectively connected" with the conduct of a U.S. trade or business, as described below, any such "effectively connected" U.S. source gross shipping income, net of applicable deductions, would be subject to the U.S. federal corporate income tax currently imposed at rates of up to 35%. In addition, we may be subject to the 30% "branch profits" tax on earnings effectively connected with the conduct of such trade or business, as determined after allowance for certain adjustments, and on certain interest paid or deemed paid attributable to the conduct of our U.S. trade or business.

Our U.S. source gross shipping income would be considered "effectively connected" with the conduct of a U.S. trade or business only if:

we have, or are considered to have, a fixed place of business in the United States involved in the earning of shipping income; and

substantially all of our U.S. source gross shipping income is attributable to regularly scheduled transportation, such as the operation of a vessel that follows a published schedule with repeated sailings at regular intervals between the same points for voyages that begin or end in the United States.

We do not intend to have, or permit circumstances that would result in having, any vessel operating to the United States on a regularly scheduled basis. Based on the foregoing and on the expected mode of our shipping operations and other activities, we believe that none of our U.S. source gross shipping income will be "effectively connected" with the conduct of a U.S. trade or business.

United States Taxation of Gain on Sale of Vessels

Regardless of whether we qualify for exemption under Section 883, we will not be subject to United States federal income taxation with respect to gain realized on a sale of a vessel, provided the sale is considered to occur outside of the United States under United States federal income tax principles. In general, a sale of a vessel will be considered to occur outside of the United States for this purpose if title to the vessel, and risk of loss with respect to the vessel, pass to the buyer outside of the United States. It is expected that any sale of a vessel by us will be considered to occur outside of the United States.

United States Federal Income Taxation of U.S. Holders

Taxation of Distributions Paid on Common Stock

Subject to the passive foreign investment company, or PFIC, rules discussed below, any distributions made by us with respect to common shares to a U.S. Holder will generally constitute dividends, which may be taxable as ordinary income or "qualified dividend income" as described in more detail below, to the extent of our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Distributions in excess of our earnings and profits will be treated first as a non-taxable return of capital to the extent of the U.S. Holder's tax basis in his common shares on a dollar-for-dollar basis and thereafter as capital gain. Because we are not a U.S. corporation, U.S. Holders that are corporations will not be entitled to claim a dividends-received deduction with respect to any distributions they receive from us.

Dividends paid on common shares to a U.S. Holder which is an individual, trust, or estate (a "U.S. Non-Corporate Holder") will generally be treated as "qualified dividend income" that is taxable to such shareholders at preferential U.S. federal income tax rates provided that (1) the common shares are readily tradable on an established securities market in the United States (such as the NASDAQ Global Market on which the common shares were listed and the Nasdaq Capital Market on which the common shares are currently listed); (2) we are not a passive foreign investment company, or PFIC, for the taxable year during which the dividend is paid or the immediately preceding taxable year (which we do not believe we are, have been or will be); (3) the U.S. Non-Corporate Holder has owned the common shares for more than 60 days in the 121-day period beginning 60 days before the date on which the common shares become ex-dividend; and (4) certain other conditions are met.

S-14

Any dividends paid by us which are not eligible for these preferential rates will be taxed as ordinary income to a U.S. Holder.

Special rules may apply to any ''extraordinary dividend''—generally, a dividend in an amount which is equal to or in excess of 10% of a shareholder's adjusted basis in a common share—paid by us. If we pay an "extraordinary dividend" on our common stock that is treated as "qualified dividend income," then any loss derived by a U.S. Non-Corporate Holder from the sale or exchange of such common stock will be treated as long-term capital loss to the extent of such dividend.

Sale, Exchange or other Disposition of Common Shares

Assuming we do not constitute a PFIC for any taxable year, a U.S. Holder generally will recognize taxable gain or loss upon a sale, exchange or other disposition of our common shares in an amount equal to the difference between the amount realized by the U.S. Holder from such sale, exchange or other disposition and the U.S. Holder's tax basis in such stock. Such gain or loss will be treated as long-term capital gain or loss if the U.S. Holder's holding period in the common shares is greater than one year at the time of the sale, exchange or other disposition. A U.S. Holder's ability to deduct capital losses is subject to certain limitations.

Passive Foreign Investment Company Rules

Special U.S. federal income tax rules apply to a U.S. Holder that holds stock in a foreign corporation classified as a PFIC for U.S. federal income tax purposes. In general, we will be treated as a PFIC with respect to a U.S. Holder if, for any taxable year in which such holder held our common shares, either:

at least 75% of our gross income for such taxable year consists of passive income (e.g., dividends, interest, capital gains and rents derived other than in the active conduct of a rental business); or

at least 50% of the average value of the assets held by the corporation during such taxable year produce, or are held for the production of, passive income.

For purposes of determining whether we are a PFIC, we will be treated as earning and owning its proportionate share of the income and assets, respectively, of any of its subsidiary corporations in which it owns at least 25% of the value of the subsidiary's stock. Income earned, or deemed earned, by us in connection with the performance of services would not constitute passive income. By contrast, rental income, which includes bareboat hire, would generally constitute "passive income" unless we are treated under specific rules as deriving rental income in the active conduct of a trade or business.

Based on our current operations and future projections, we do not believe that we are, nor do we expect to become, a PFIC with respect to any taxable year. Although there is no legal authority directly on point, our belief is based principally on the position that, for purposes of determining whether we are a PFIC, the gross income we derive or are deemed to derive from the time chartering and voyage chartering activities of our wholly-owned subsidiaries should constitute services income, rather than rental income. Correspondingly, we believe that such income does not constitute passive income, and the assets that we or our wholly-owned subsidiaries own and operate in connection with the production of such income, in particular, the vessels, do not constitute passive assets for purposes of determining whether we are a PFIC. We believe there is substantial legal authority supporting its position consisting of case law and Internal Revenue Service pronouncements concerning the characterization of income derived from time charters and voyage charters as services income for other tax purposes. However, there is also authority which characterizes time charter income as rental income rather than services income for other tax purposes. It should be noted that in the absence of any legal authority specifically relating to the statutory provisions governing PFICs, the Internal Revenue Service or a court could disagree with this position. In addition, although we intend to conduct its affairs in a manner to avoid being classified as a PFIC with respect to any taxable year, there can be no assurance that the nature of our operations will not change in the future.

As discussed more fully below, if we were to be treated as a PFIC for any taxable year, a U.S. Holder would be subject to different taxation rules depending on whether the U.S. Holder makes an election to treat us as a "Qualified Electing Fund," which election is referred to as a "QEF election." As an alternative to making a QEF election, a U.S. Holder should be able to make a "mark-to-market" election with respect to the common shares, as discussed below. In addition, if we were to be treated as a PFIC for any taxable year ending on or after December 31, 2013, a U.S. Holder would be required to file an IRS Form 8621 for the year with respect to such holder's common stock.

S-15

Taxation of U.S. Holders Making a Timely QEF Election

If a U.S. Holder makes a timely QEF election, which U.S. Holder is referred to as an "Electing Holder," the Electing Holder must report each year for U.S. federal income tax purposes his pro rata share of the our ordinary earnings and its net capital gain, if any, for our taxable year that ends with or within the taxable year of the Electing Holder, regardless of whether or not distributions were received from us by the Electing Holder. The Electing Holder's adjusted tax basis in the common shares will be increased to reflect taxed but undistributed earnings and profits. Distributions of earnings and profits that had been previously taxed will result in a corresponding reduction in the adjusted tax basis in the common shares and will not be taxed again once distributed. An Electing Holder would generally recognize capital gain or loss on the sale, exchange or other disposition of the common shares. A U.S. Holder would make a QEF election with respect to any year that we are a PFIC by filing IRS Form 8621 with his, her or its U.S. federal income tax return. After the end of each taxable year, we will determine whether we were a PFIC for such taxable year. If we determine or otherwise become aware that we are a PFIC for any taxable year, we will provide each U.S. Holder with all necessary information, including a PFIC Annual Information Statement, in order to enable such holder to make a QEF election for such taxable year.

Taxation of U.S. Holders Making a "Mark-to-Market" Election

Alternatively, if we were to be treated as a PFIC for any taxable year and, as anticipated, our common stock is treated as "marketable stock," a U.S. Holder would be allowed to make a "mark-to-market" election with respect to our common shares. If that election is made, the U.S. Holder generally would include as ordinary income in each taxable year the excess, if any, of the fair market value of the common shares at the end of the taxable year over such U.S. Holder's adjusted tax basis in the common shares. The U.S. Holder would also be permitted an ordinary loss in respect of the excess, if any, of the U.S. Holder's adjusted tax basis in the common shares over its fair market value at the end of the taxable year, but only to the extent of the net amount previously included in income as a result of the mark-to-market election. A U.S. Holder's tax basis in his common shares would be adjusted to reflect any such income or loss amount. Gain realized on the sale, exchange or other disposition of the common shares would be treated as ordinary income, and any loss realized on the sale, exchange or other disposition of the common shares would be treated as ordinary loss to the extent that such loss does not exceed the net mark-to-market gains previously included by the U.S. Holder.

Taxation of U.S. Holders Not Making a Timely QEF or Mark-to-Market Election

Finally, if we were to be treated as a PFIC for any taxable year, a U.S. Holder who does not make either a QEF election or a "mark-to-market" election for that year, whom we refer to as a "Non-Electing Holder," would be subject to special rules with respect to (1) any excess distribution (i.e., the portion of any distributions received by the Non-Electing Holder on our common stock in a taxable year in excess of 125 percent of the average annual distributions received by the Non-Electing Holder in the three preceding taxable years, or, if shorter, the Non-Electing Holder's holding period for the common stock), and (2) any gain realized on the sale, exchange or other disposition of our common stock. Under these special rules:

the excess distribution or gain would be allocated ratably over the Non-Electing Holders' aggregate holding period for the common stock;

the amount allocated to the current taxable year and any taxable year before we became a passive foreign investment company would be taxed as ordinary income; and

the amount allocated to each of the other taxable years would be subject to tax at the highest rate of tax in effect for the applicable class of taxpayer for that year, and an interest charge for the deemed deferral benefit would be imposed with respect to the resulting tax attributable to each such other taxable year.

These penalties would not apply to a pension or profit sharing trust or other tax-exempt organization that did not borrow funds or otherwise utilize leverage in connection with its acquisition of our common stock. If a Non-Electing Holder who is an individual dies while owning our common stock, such Non-Electing Holder's successor generally would not receive a step-up in tax basis with respect to such stock.

S-16

United States Federal Income Taxation of Non-U.S. Holders

Dividends paid to a Non-U.S. Holder with respect to our common stock generally should not be subject to U.S. federal income tax, unless the dividends are effectively connected with the Non-U.S. Holder's conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, are attributable to a permanent establishment or fixed base that such holder maintains in the United States).

In addition, a Non-U.S. Holder generally should not be subject to U.S. federal income tax on any gain attributable to a sale or other disposition of our common stock unless such gain is effectively connected with its conduct of a trade or business in the United States (and, if required by an applicable income tax treaty, is attributable to a permanent establishment or fixed base that such holder maintains in the United States) or the Non-U.S. Holder is an individual who is present in the United States for 183 days or more in the taxable year of sale or other disposition and certain other conditions are met (in which case such gain from United States sources may be subject to tax at a 30% rate or a lower applicable tax treaty rate).

Dividends and gains that are effectively connected with the Non-U.S. Holder's conduct of a trade or business in the United States (and, if required by an applicable income tax treaty, are attributable to a permanent establishment or fixed base in the United States) generally should be subject to tax in the same manner as for a U.S. Holder and, if the Non-U.S. Holder is a corporation for U.S. federal income tax purposes, it also may be subject to an additional branch profits tax at a 30% rate or a lower applicable tax treaty rate.

Backup Withholding and Information Reporting

In general, information reporting for U.S. federal income tax purposes should apply to distributions made on our common stock within the United States to a non-corporate U.S. Holder and to the proceeds from sales and other dispositions of our common stock to or through a U.S. office of a broker by a non-corporate U.S. Holder. Payments made (and sales and other dispositions effected at an office) outside the United States will be subject to information reporting in limited circumstances.

In addition, backup withholding of U.S. federal income tax, currently at a rate of 28%, generally should apply to distributions paid on our common stock to a non-corporate U.S. Holder and the proceeds from sales and other dispositions of our common stock by a non-corporate U.S. Holder, who:

fails to provide an accurate taxpayer identification number;

is notified by the IRS that backup withholding is required; or

fails in certain circumstances to comply with applicable certification requirements.

A Non-U.S. Holder generally may eliminate the requirement for information reporting and backup withholding by providing certification of its foreign status, under penalties of perjury, on a duly executed applicable IRS Form W-8 or by otherwise establishing an exemption.

Backup withholding is not an additional tax. Rather, the amount of any backup withholding generally should be allowed as a credit against a U.S. Holder's or a Non-U.S. Holder's U.S. federal income tax liability and may entitle such holder to a refund, provided that certain required information is timely furnished to the IRS.

Individuals who are U.S. Holders (and to the extent specified in applicable Treasury regulations, certain individuals who are Non-U.S. Holders and certain U.S. entities) who hold "specified foreign financial assets" (as defined in Section 6038D of the Code) are required to file IRS Form 8938 with information relating to the asset for each taxable year in which the aggregate value of all such assets exceeds $75,000 at any time during the taxable year or $50,000 on the last day of the taxable year (or such higher dollar amount as prescribed by applicable Treasury regulations). Specified foreign financial assets would include, among other assets, the common shares, unless the shares held through an account maintained with a U.S. financial institution. Substantial penalties apply to any failure to timely file IRS Form 8938, unless the failure is shown to be due to reasonable cause and not due to willful neglect. Additionally, in the event an individual U.S. Holder (and to the extent specified in applicable Treasury regulations, an individual Non-U.S. Holder or a U.S. entity) that is required to file IRS Form 8938 does not file such form, the statute of limitations on the assessment and collection of U.S. federal income taxes of such holder for the related tax year may not close until three years after the date that the required information is filed. U.S. Holders (including U.S. entities) and Non-U.S. Holders are encouraged consult their own tax advisors regarding their reporting obligations under this legislation.

Marshall Islands Tax Consequences

We are incorporated in the Marshall Islands. Under current Marshall Islands law, we are not subject to tax on income or capital gains, no Marshall Islands withholding tax will be imposed upon payment of dividends by us to its shareholders, and holders of our common stock that are not residents of or domiciled or carrying on any commercial activity in the Marshall Islands will not be subject to Marshall Islands tax on the sale or other disposition of our common stock.

PLAN OF DISTRIBUTION

We have entered into an equity distribution agreement with Maxim Group LLC pursuant to which we may issue and sell up to an aggregate of $20,000,000 of our common shares from time to time solely through Maxim Group LLC acting as agent. A copy of the equity distribution agreement is being filed as an exhibit to a Report on Form 6-K filed with the Commission on February 3, 2017 and incorporated by reference herein.

Upon delivery of a placement notice and subject to the terms and conditions of the equity distribution agreement, Maxim Group LLC may sell our common shares by any method permitted by law deemed to be an "at-the-market" offering as defined in Rule 415 promulgated under the Securities Act of 1933, as amended, or the Securities Act, including sales made directly on the Nasdaq Capital Market, on any other existing trading market for our common shares or to or through a market maker. Maxim Group LLC may also sell our common shares by any other method permitted by law, including in privately negotiated transactions. We or Maxim Group LLC may terminate the equity distribution agreement and the offering of our common shares upon notice.

We will pay Maxim Group LLC in cash, upon each sale of our common shares pursuant to the equity distribution agreement, a commission equal to 3% of the aggregate gross proceeds from the sale of our common shares. Because there is no minimum offering amount required as a condition to this offering, the actual total public offering amount, commissions and proceeds to us, if any, are not determinable at this time. We have agreed to reimburse Maxim Group LLC upon request for its reasonable costs and out-of-pocket expenses incurred in connection with the at the market offering, including the fees and out-of-pocket expenses of its legal counsel, of up to $75,000. Additionally, we have agreed to reimburse Maxim Group LLC $7,500 for its legal fees on each bringdown date (as defined in the equity distribution agreement) while this offering is open.

Settlement for sales of common shares will occur on the third business day following the date on which any sales are made, or on some other date that is agreed upon by us and Maxim Group LLC in connection with a particular transaction. There is no arrangement for funds to be received in an escrow, trust or similar arrangement. Sales of our common shares as contemplated in this prospectus supplement will be settled through the facilities of The Depository Trust Company or by such other means as we and Maxim Group LLC may agree upon.

Maxim Group LLC will act as sales agent on a commercially reasonable efforts basis consistent with its normal trading and sales practices and applicable state and federal laws, rules and regulations and the rules of the Nasdaq Capital Market. In connection with the sale of the common shares on our behalf, Maxim Group LLC will be deemed to be an "underwriter" within the meaning of the Securities Act and the compensation of Maxim Group LLC will be deemed to be underwriting commissions or discounts. We have agreed to provide indemnification and contribution to Maxim Group LLC against certain civil liabilities, including liabilities under the Securities Act.

The offering of our common shares pursuant to the equity distribution agreement will terminate upon the earlier of the (i) sale of all of our common shares provided for in this prospectus supplement, or (ii) termination of the equity distribution agreement as permitted therein. We may terminate the equity distribution agreement with 30 days of prior written notice. Maxim Group LLC may terminate the equity distribution agreement at any time upon written notice.

Maxim Group LLC and its affiliates may in the future provide various investment banking, commercial banking and other financial services for us and our affiliates, for which services they may in the future receive customary fees. To the extent required by Regulation M, Maxim Group LLC will not engage in any market making activities involving our common shares while the offering is ongoing under this prospectus supplement.

This prospectus supplement in electronic format may be made available on a web site maintained by Maxim Group LLC and Maxim Group LLC may distribute this prospectus supplement electronically.

The supplement may also add, update or change the information contained in this prospectus. If there is any inconsistency between the information in this prospectus and any prospectus supplement, you should rely on the prospectus supplement. Before purchasing any securities, you should read carefully both this prospectus and any supplement, together with the additional information described below.

Forms of the indenture and other documents establishing the terms of the offered securities are filed as exhibits to the registration statement.

SUMMARY

This section summarizes some of the information that is contained in or incorporated by reference in this prospectus. As an investor or prospective investor, you should review carefully all of the information contained or incorporated by reference in this prospectus and any accompanying prospectus supplement, including the "Risk Factors" and our financial statements and related notes contained or incorporated by reference herein and therein, before making an investment decision.

Unless the context otherwise requires, as used in this prospectus, the terms "Company," "we," "us," and "our" refer to Seanergy Maritime Holdings Corp. and all of its subsidiaries, and "Seanergy Maritime Holdings Corp." refers only to Seanergy Maritime Holdings Corp. and not to its subsidiaries. We use the term deadweight ton, or dwt, in describing the size of vessels. Dwt, expressed in metric tons each of which is equivalent to 1,000 kilograms, refers to the maximum weight of cargo and supplies that a vessel can carry. Our reporting currency is the U.S. dollar and all references in this prospectus to "$" or "dollars" are to U.S. dollars.

Our Company

We intend to expand our fleet further and are actively reviewing the market in order to identify suitable vessel acquisitions. We expect to finance these acquisitions with equity provided through capital markets transactions and our shareholders and/or new loan arrangements.

We believe we have established a reputation in the international ocean transport industry for operating and maintaining vessels with high standards of performance, reliability and safety. We have assembled a management team comprised of executives who have extensive experience operating large and diversified fleet, and who have strong ties to a number of international lending institutions and charterers.

Corporate Structure

We currently own one Capesize vessel. We intend to continue to review the market in order to identify potential acquisition targets which will be accretive to our earnings per share. Our acquisition strategy focuses on newbuilding or secondhand dry bulk carriers, although we may acquire vessels in other sectors which we believe offer attractive investment opportunities.

The current address of our principal executive office is 16 Grigoriou Lambraki Street, 2nd Floor, 166 74 Glyfada, Athens, Greece. The telephone number of our registered office is +011-30 2130181507. Our corporate website address is www.seanergymaritime.com. The information contained on our website does not constitute part of this prospectus.

Management of Our Fleet

V.Ships Limited, or V.Ships, performs the technical management of our fleet.

Fidelity Marine Inc., or Fidelity, performs the commercial management of our fleet.

Our vessel's insurances, bunkering and operation are provided through Seanergy Shipmanagement Corp., or Seanergy Shipmanagement, one of our wholly-owned subsidiaries.

Management Agreements

Through Leader Shipping Co., or Leader, our wholly-owned subsidiary and the owner of the M/V Leadership, we have entered into a technical management agreement with V.Ships with respect to the M/V Leadership. Pursuant to this management agreement, V.Ships performs certain duties that include general administrative and support services necessary for the operation of such vessel, including, without limitation, crewing and other technical management, freight management, accounting related to vessels, provisions and operation and, subject to our instructions, sale and purchase of vessels. Pursuant to the management agreement, we pay a monthly management fee of $10,800.

Seanergy Shipmanagement, our wholly-owned subsidiary, has entered into an agreement with Leader, for the provision of the vessel's insurances, bunkering and operation. Leader shall reimburse Seanergy Shipmanagement for all reasonable running and/or out of pocket expenses in relation to this agreement. The agreement between Leader and Seanergy Shipmanagement is for an indefinite period until terminated by either party giving to the other notice in writing.

Through Seanergy Management Corp., or Seanergy Management, our wholly-owned subsidiary, we have entered into a commercial management agreement with Fidelity with respect to our new vessel, the M/V Leadership. Pursuant to this commercial management agreement, Fidelity performs the commercial management of the vessel and her employment. The Company shall reimburse Fidelity for all reasonable running and/or out of pocket expenses, including but not limited to, telephone, fax, stationary and printing expenses, as well as any pre-approved travelling expenses in relation to this agreement.

RISK FACTORS

An investment in our securities involves a high degree of risk and uncertainty. You should carefully consider the risks discussed under the caption "Risk Factors" in our Annual Report on Form 20-F for the year ended December 31, 2014, and incorporated by reference herein, as well as the other information included in this prospectus and the other documents we have incorporated by reference in this prospectus, including the section entitled "Risk Factors" in future Annual Reports before deciding to invest in our securities. If any of the risks occur, our business, financial conditions or results of operations may be materially and adversely affected. This prospectus also contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in the forward-looking statements as a result of the risks below.

If the Share Price of Our Common Shares Fluctuates After this Offering, You could Lose a Significant Part of Your Investment.

The market price of our common shares may be influenced by many factors, many of which are beyond our control, including the other risks described under the heading "Risk Factors—Risk Factors Related to Our Common Shares" in our Annual Report on Form 20-F for the year ended December 31, 2014 and the following:

the failure of securities analysts to publish research about us after this offering, or analysts making changes in their financial estimates;

announcements by us or our competitors of significant contracts, acquisitions or capital commitments;

variations in quarterly operating results;

general economic conditions;

terrorist or piracy acts;

future sales of our common shares or other securities; and

investors' perception of us and the international containership sector.

On January 28, 2015, we received notice from the Nasdaq Stock Market, or the Nasdaq, indicating that we were no longer in compliance with Nasdaq Listing Rule 5550(a)(2) because the closing share bid price was below the minimum $1.00 per share requirement for 30 consecutive business days. We had 180 days, or until July 27, 2015, to regain compliance. On July 28, 2015, the Company received a notice from Nasdaq, granting the Company an extension of time until January 25, 2016, to regain compliance with Nasdaq Listing Rule 5550(a)(2). Under the terms of the extension, if compliance cannot be demonstrated by January 25, 2016, the staff of the SEC, or the Staff, will provide written notification that the Company's securities will be delisted. At that time, the Company may appeal the Staff's determination to a Hearings Panel.

We intend to cure the deficiency within the prescribed grace period. During this time, our common stock will continue to be listed and trade on the Nasdaq Capital Market. However, if we do not regain compliance with the Nasdaq's continued listing standards and delist from the Nasdaq and our common shares are not subsequently listed and registered on another national securities exchange, we will be unable to meet certain transaction requirements that would effectively prevent us from offering and selling additional common shares under this registration statement.

As a result of these factors, investors in our common shares may not be able to resell their common shares at or above the initial offering price. These broad market and industry factors may materially reduce the market price of our common shares, regardless of our operating performance.

We May Issue Additional Common Shares or Other Equity Securities Without Your Approval, Which Would Dilute Your Ownership Interests and May Depress the Market Price of Our Common Shares .

We may issue additional common shares or other equity securities of equal or senior rank in the future in connection with, among other things, future vessel acquisitions or repayment of outstanding indebtedness, without shareholder approval, in a number of circumstances.

Our issuance of additional common shares or other equity securities of equal or senior rank would have the following effects:

our existing shareholders' proportionate ownership interest in us will decrease;

the amount of cash available for dividends payable on our common shares may decrease;

the relative voting strength of each previously outstanding common share may be diminished; and

the market price of our common shares may decline.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This prospectus contains certain forward-looking statements made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Our forward-looking statements include, but are not limited to, statements regarding our or our management's expectations, hopes, beliefs, intentions or strategies regarding the future and other statements other than statements of historical fact. In addition, any statements that refer to projections, forecasts or other characterizations of future events or circumstances, including any underlying assumptions, are forward-looking statements. The words "anticipate," "believe," "continue," "could," "estimate," "expect," "intend," "may," "might," "plan," "possible," "potential," "predict," "project," "should," "would" and similar expressions may identify forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking. Forward-looking statements in this prospectus may include, for example, statements about:

our ability to continue as a going concern;

our future operating or financial results;

our financial condition and liquidity, including our ability to pay amounts that we owe, obtain additional financing in the future to fund capital expenditures, acquisitions and other general corporate activities;

our ability to come to a satisfactory resolution with our lenders in our ongoing debt restructuring process;

our ability to pay dividends in the future;

shipping industry trends, including charter rates and factors affecting vessel supply and demand;

future, pending or recent acquisitions and disposition, business strategy, areas of possible expansion or contraction, and expected capital spending or operating expenses;

the useful lives and changes in the value of our vessels and their impact on our compliance with loan covenants;

availability of crew, number of off-hire days, classification survey requirements and insurance costs;

global and regional economic and political conditions;

our ability to leverage the relationships and reputation in the dry bulk shipping industry of V.Ships and Fidelity;

changes in seaborne and other transportation patterns;

changes in governmental rules and regulations or actions taken by regulatory authorities;

potential liability from future litigation and incidents involving our vessels;

acts of terrorism and other hostilities;

the number of newbuildings under construction in the dry bulk industry;

future charter hire rates and vessel values;

loss of our customers, charters or vessels;

the aging of our fleet and increases in operating costs; and

damage to our vessels.

See the section entitled "Risk Factors," on page 3 of this prospectus and in our Annual Report on Form 20-F for the fiscal year ended December 31, 2014, and incorporated by reference herein, for a more complete discussion of these risks and uncertainties and for other risks and uncertainties. These factors and the other risk factors described in this prospectus are not necessarily all of the important factors that could cause actual results or developments to differ materially from those expressed in any of our forward-looking statements. Other unknown or unpredictable factors also could harm our results. Consequently, there can be no assurance that actual results or developments anticipated by us will be realized or, even if substantially realized, that they will have the expected consequences to, or effects on, us. Given these uncertainties, prospective investors are cautioned not to place undue reliance on such forward-looking statements.

(1)	We have not issued any preferred stock as of the date of this prospectus.

(2)

For purposes of computing the consolidated ratio of earnings to fixed charges, "earnings" consist of pre-tax income from continuing operations prepared under U.S. GAAP plus fixed charges and "fixed charges" represent interest incurred and amortization of deferred financing costs. The consolidated ratio of earnings to fixed charges is a ratio that we are required to present in this prospectus supplement and has been calculated in accordance with SEC rules and regulations. This ratio has no application to our credit facilities, and we believe is not a ratio generally used by investors to evaluate our overall operating performance.

(3)	The interest component of rental expense is estimated to equal 1/3 of such expense, which is considered reasonable approximation of the interest factor.

USE OF PROCEEDS

We intend to use net proceeds from the sale of the securities as set forth in the applicable prospectus supplement.

CAPITALIZATION

Each prospectus supplement will include information on our consolidated capitalization.

DILUTION

Information about the amount by which the offering price of our common shares issued pursuant to this prospectus exceeds the net tangible book value per share of our common shares following such issuance will be included in a prospectus supplement.

PLAN OF DISTRIBUTION

We may sell or distribute the securities included in this prospectus through underwriters, through agents, to dealers, in private transactions, at market prices prevailing at the time of sale, at prices related to the prevailing market prices, or at negotiated prices.

In addition, we may sell some or all of our securities included in this prospectus, through:

a block trade in which a broker-dealer may resell a portion of the block, as principal, in order to facilitate the transaction;

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

ordinary brokerage transactions and transactions in which a broker solicits purchasers.

In addition, we may enter into option or other types of transactions that require us or them to deliver our securities to a broker-dealer, who will then resell or transfer the securities under this prospectus. We may enter into hedging transactions with respect to our securities. For example, we may:

enter into transactions involving short sales of our shares of common stock by broker-dealers;

sell shares of common stock short themselves and deliver the shares to close out short positions;

enter into option or other types of transactions that require us to deliver shares of common stock to a broker-dealer, who will then resell or transfer the shares of common stock under this prospectus; or

loan or pledge the shares of common stock to a broker-dealer, who may sell the loaned shares or, in the event of default, sell the pledged shares.

We may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third party may use securities pledged by us or borrowed from us to settle those sales or to close out any related open borrowings of stock, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of stock. The third party in such sale transactions will be an underwriter and, if not identified in this prospectus, will be identified in the applicable prospectus supplement (or a post-effective amendment). In addition, we may otherwise loan or pledge securities to a financial institution or other third party that in turn may sell the securities short using this prospectus. Such financial institution or other third party may transfer its economic short position to investors in our securities or in connection with a concurrent offering of other securities.

Any broker-dealers or other persons acting on our behalf that participate with us in the distribution of the securities, may be deemed to be underwriters, and any commissions received or profit realized by them on the resale of the securities, may be deemed to be underwriting discounts and commissions under the Securities Act of 1933, as amended, or the Securities Act. As of the date of this prospectus, we are not a party to any agreement, arrangement or understanding between any broker or dealer and us with respect to the offer or sale of the securities pursuant to this prospectus.

At the time that any particular offering of securities is made, to the extent required by the Securities Act, a prospectus supplement will be distributed, setting forth the terms of the offering, including the aggregate number of securities being offered, the purchase price of the securities, the initial offering price of the securities, the names of any underwriters, dealers or agents, any discounts, commissions and other items constituting compensation from us, and any discounts, commissions or concessions allowed or reallowed or paid to dealers. Furthermore, we, our executive officers, our directors and major shareholders may agree, subject to certain exemptions, that for a certain period from the date of the prospectus supplement under which the securities are offered, we and they will not, without the prior written consent of an underwriter, offer, sell, contract to sell, pledge or otherwise dispose of any of shares of our common stock or any securities convertible into or exchangeable for shares of our common stock. However, an underwriter, in its sole discretion, may release any of the securities subject to these lock-up agreements at any time without notice.

Underwriters or agents could make sales in privately negotiated transactions and/or any other method permitted by law, including sales deemed to be an at-the-market offering as defined in Rule 415 promulgated under the Securities Act, which includes sales made directly on or through the Nasdaq Capital Market, the existing trading market for our shares of common stock, or sales made to or through a market maker other than on an exchange.

We will bear costs relating to all of the securities offered and sold by us under this registration statement.

ENFORCEABILITY OF CIVIL LIABILITIES

We are a Marshall Islands company, and our principal executive office is located outside of the United States in Greece. Some of our directors, officers and the experts named in this registration statement reside outside the United States. In addition, a substantial portion of our assets and the assets of certain of our directors, officers and experts are located outside of the United States. As a result, it may be difficult or impossible for U.S. investors to serve process within the United States upon us or any of these persons. You may also have difficulty enforcing, both in and outside the United States, judgments you may obtain in United States courts against us or these persons in any action, including actions based upon the civil liability provisions of United States federal or state securities laws.

Furthermore, there is substantial doubt that courts in the countries in which we or our subsidiaries are incorporated or where our assets or the assets of our subsidiaries, directors or officers and such experts are located (i) would enforce judgments of U.S. courts obtained in actions against us or our subsidiaries, directors or officers and such experts based upon the civil liability provisions of applicable U.S. federal and state securities laws or (ii) would enforce, in original actions, liabilities against us or our subsidiaries, directors or officers and such experts based on those laws.

General

Our Amended and Restated Articles of Incorporation and Second Amended and Restated By-laws.

Our purpose is to engage in any lawful act or activity for which corporations may now or hereafter be organized under the Marshall Islands Business Corporations Act, or BCA. Our Amended and Restated Articles of Incorporation, and further amendments thereto, and the Second Amended and Restated By-laws do not impose any limitations on the ownership rights of our shareholders.

Under our Second Amended and Restated By-laws, annual shareholder meetings will be held at a time and place selected by our Board of Directors. The meetings may be held in or outside of the Marshall Islands. Special meetings of the shareholders, unless otherwise prescribed by law, may be called for any purpose or purposes at any time exclusively by the Board of Directors. Notice of every annual and special meeting of shareholders shall be given at least 15 but not more than 60 days before such meeting to each shareholder of record entitled to vote thereat.

Directors.

Our directors are elected by a plurality of the votes cast at a meeting of the shareholders by the holders of shares entitled to vote in the election. Our Amended and Restated Articles of Incorporation and Second Amended and Restated By-laws prohibit cumulative voting in the election of directors.

The Board of Directors must consist of at least one member and not more than thirteen. Each director shall be elected to serve until the third succeeding annual meeting of shareholders and until his successor shall have been duly elected and qualified, except in the event of his death, resignation, removal, or the earlier termination of his term of office. The Board of Directors has the authority to fix the amounts which shall be payable to the members of our Board of Directors, and to members of any committee, for attendance at any meeting or for services rendered to us.

Classified Board

Our Amended and Restated Articles of Incorporation provide for the division of our Board of Directors into three classes of directors, with each class as nearly equal in number as possible, serving staggered, three-year terms. Approximately one-third of our Board of Directors will be elected each year. This classified board provision could discourage a third party from making a tender offer for our shares or attempting to obtain control of our company. It could also delay shareholders who do not agree with the policies of the Board of Directors from removing a majority of the Board of Directors for two years.

Election and Removal

Our Amended and Restated Articles of Incorporation and Amended and Restated by-laws require parties other than the Board of Directors to give advance written notice of nominations for the election of directors. Our Second Amended and Restated By-laws provide that our directors may be removed only for cause and only upon the affirmative vote of the majority of the outstanding shares of our capital stock entitled to vote for those directors. These provisions may discourage, delay or prevent the removal of incumbent officers and directors.

Dissenters' Rights of Appraisal and Payment . Under the Business Corporation Act of the Republic of the Marshall Islands, or BCA, our shareholders have the right to dissent from various corporate actions, including any merger or sale of all or substantially all of our assets not made in the usual course of our business, and receive payment of the fair value of their shares. In the event of any further amendment of the articles, a shareholder also has the right to dissent and receive payment for his or her shares if the amendment alters certain rights in respect of those shares. The dissenting shareholder must follow the procedures set forth in the BCA to receive payment. In the event that we and any dissenting shareholder fail to agree on a price for the shares, the BCA procedures involve, among other things, the institution of proceedings in the circuit court in the judicial circuit in the Marshall Islands in which our Marshall Islands office is situated. The value of the shares of the dissenting we and any dissenting shareholder fail to agree on a price for the shares, the BCA procedures involve shareholder is fixed by the court after reference, if the court so elects, to the recommendations of a court-appointed appraiser.

Shareholders' Derivative Actions . Under the BCA, any of our shareholders may bring an action in our name to procure a judgment in our favor, also known as a derivative action, provided that the shareholder bringing the action is a holder of common shares both at the time the derivative action is commenced and at the time of the transaction to which the action relates.

Anti-takeover Provisions of our Charter Documents . Several provisions of our Amended and Restated Articles of Incorporation and Amended and Restated by-laws may have anti-takeover effects. These provisions are intended to avoid costly takeover battles, lessen our vulnerability to a hostile change of control and enhance the ability of our Board of Directors to maximize shareholder value in connection with any unsolicited offer to acquire us. However, these anti-takeover provisions, which are summarized below, could also discourage, delay or prevent (1) the merger or acquisition of our company by means of a tender offer, a proxy contest or otherwise, that a shareholder may consider in its best interest and (2) the removal of incumbent officers and directors.

Limited Actions by Shareholders

Our Amended and Restated Articles of Incorporation and our Amended and Restated By-laws provide that any action required or permitted to be taken by our shareholders must be effected at an annual or special meeting of shareholders or by the unanimous written consent of our shareholders.

Our Amended and Restated Articles of Incorporation and our Amended and Restated By-laws provide that only our Board of Directors may call special meetings of our shareholders and the business transacted at the special meeting is limited to the purposes stated in the notice. Accordingly, a shareholder may be prevented from calling a special meeting for shareholder consideration of a proposal over the opposition of our Board of Directors and shareholder consideration of a proposal may be delayed until the next annual meeting.

Blank Check Preferred Stock

Under the terms of our Amended and Restated Articles of Incorporation, our Board of Directors has authority, without any further vote or action by our shareholders, to issue up to 25,000,000 shares of blank check preferred stock. Our Board of Directors may issue shares of preferred stock on terms calculated to discourage, delay or prevent a change of control of our company or the removal of our management.

Transfer Agent

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

Listing

Our common shares traded on the Nasdaq Capital Market under the symbol "SHIP."

DESCRIPTION OF DEBT SECURITIES

We may issue debt securities from time to time in one or more series, under one or more indentures, each dated as of a date on or prior to the issuance of the debt securities to which it relates. We may issue senior debt securities and subordinated debt securities pursuant to separate indentures, a senior indenture and a subordinated indenture, respectively, in each case between us and the trustee named in the indenture. These indentures will be filed either as exhibits to an amendment to this Registration Statement, or as an exhibit to a Securities Exchange Act of 1934, or Exchange Act, report that will be incorporated by reference to this registration statement or a prospectus supplement. We will refer to any or all of these reports as "subsequent filings." The senior indenture and the subordinated indenture, as amended or supplemented from time to time, are sometimes referred to individually as an "indenture" and collectively as the "indentures." Each indenture will be subject to and governed by the Trust Indenture Act. The aggregate principal amount of debt securities which may be issued under each indenture will be unlimited and each indenture will contain the specific terms of any series of debt securities or provide that those terms must be set forth in or determined pursuant to, an authorizing resolution, as defined in the applicable prospectus supplement, and/or a supplemental indenture, if any, relating to such series.

Our statements below relating to the debt securities and the indenture are summaries of their anticipated provisions, are not complete and are subject to, and are qualified in their entirety by reference to, all of the provisions of the applicable indenture and any applicable United States federal income tax considerations as well as any applicable modifications of or additions to the general terms described below in the applicable prospectus supplement or supplemental indenture. For a description of the terms of a particular issue of debt securities, reference must be made to both the related prospectus supplement and to the following description.

General

Neither indenture limits the amount of debt securities which may be issued, and each indenture provides that debt securities may be issued up to the aggregate principal amount from time to time. The debt securities may be issued in one or more series. The senior debt securities will be unsecured and will rank in parity with all of our other unsecured and unsubordinated indebtedness. Each series of subordinated debt securities will be unsecured and subordinated to all present and future senior indebtedness of debt securities will be described in an accompanying prospectus supplement.

You should read the applicable indenture and subsequent filings relating to the particular series of debt securities for the following terms of the offered debt securities:

the designation, aggregate principal amount and authorized denominations;

the issue price, expressed as a percentage of the aggregate principal amount;

No service charge will be made for any transfer or exchange of the debt securities, but we may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection with these debt securities.

Some or all of the debt securities may be issued as discounted debt securities, bearing no interest or interest at a rate which at the time of issuance is below market rates, to be sold at a substantial discount below the stated principal amount. United States federal income tax consequences and other special considerations applicable to any discounted securities will be described in subsequent filings with the SEC relating to those securities.

We refer you to applicable subsequent filings with respect to any deletions or additions or modifications from the description contained in this prospectus.

Senior Debt

We may issue senior debt securities under a senior debt indenture. These senior debt securities would rank on an equal basis with all our other unsecured debt except subordinated debt.

Subordinated Debt

We may issue subordinated debt securities under a subordinated debt indenture. Subordinated debt would rank subordinate and junior in right of payment, to the extent set forth in the subordinated debt indenture, to all our senior debt (both secured and unsecured).

In general, the holders of all senior debt are first entitled to receive payment of the full amount unpaid on senior debt before the holders of any of the subordinated debt securities are entitled to receive a payment on account of the principal or interest on the indebtedness evidenced by the subordinated debt securities in certain events.

If we default in the payment of any principal of, or premium, if any, or interest on any senior debt when it becomes due and payable after any applicable grace period, then, unless and until the default is cured or waived or ceases to exist, we cannot make a payment on account of or redeem or otherwise acquire the subordinated debt securities.

If there is any insolvency, bankruptcy, liquidation or other similar proceeding relating to us or our property, then all senior debt must be paid in full before any payment may be made to any holders of subordinated debt securities.

Furthermore, if we default in the payment of the principal of and accrued interest on any subordinated debt securities that is declared due and payable upon an event of default under the subordinated debt indenture, holders of all our senior debt will first be entitled to receive payment in full in cash before holders of such subordinated debt can receive any payments.

Senior debt means:

the principal, premium, if any, interest and any other amounts owing in respect of our indebtedness for money borrowed and indebtedness evidenced by securities, notes, debentures, bonds or other similar instruments issued by us, including the senior debt securities or letters of credit;

all capitalized lease obligations;

all hedging obligations;

all obligations representing the deferred purchase price of property; and

all deferrals, renewals, extensions and refundings of obligations of the type referred to above;

but senior debt does not include:

subordinated debt securities; and

any indebtedness that by its terms is subordinated to, or ranks on an equal basis with, our subordinated debt securities.

Covenants

Under the terms of the indenture, a form of which is attached as an exhibit to the registration statement of which this prospectus forms a part, we covenant, among other things:

that we will duly and punctually pay the principal of and interest, if any, on the offered debt securities in accordance with the terms of such debt securities and the applicable indenture;

that so long as any offered debt securities are outstanding, we will (i) file with the SEC within the time periods prescribed by its rules and regulations and (ii) furnish to the trustee and holders of the offered debt securities all quarterly and annual financial information required to be furnished or filed with the SEC pursuant to Section 13 and 15(d) of the Exchange Act and with respect to the annual consolidated financial statements only, a report thereon by our independent auditors;

that we will deliver to the trustee after the end of each fiscal year a compliance certificate as to whether we have kept, observed, performed and fulfilled our obligations and each and every covenant contained under the applicable indenture;

that we will deliver to the trustee written notice of any event of default, with the exception of any payment default that has not given rise to a right of acceleration under the indenture;

that we will not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, which may affect the covenants or the performance of the indenture or the offered debt securities;

that we will do or cause to be done everything necessary to preserve and keep in full force and effect our corporate existence and the corporate, partnership or other existence of certain of our subsidiaries whose preservation is determined to be desirable by our board of directors and material to the holders;

that we will, and we will cause each of our subsidiaries to, pay prior to delinquency all taxes, assessments and governmental levies, except as contested in good faith and by appropriate proceedings;

that in the event we are required to pay additional interest to holders of our debt securities, we will provide notice to the trustee, and where applicable, the paying agent, of our obligation to pay such additional interest prior to the date on which any such additional interest is scheduled to be paid; and

that we will execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of the indenture.

Any series of offered debt securities may have covenants in addition to or differing from those included in the applicable indenture which will be described in subsequent filings prepared in connection with the offering of such securities, limiting or restricting, among other things:

the ability of us or our subsidiaries to incur either secured or unsecured debt, or both;

the ability to make certain payments, dividends, redemptions or repurchases;

our ability to create dividend and other payment restrictions affecting our subsidiaries;

sales of assets by us;

our ability to enter into transactions with affiliates;

our ability to incur liens; and

sale and leaseback transactions.

Each indenture and the rights of the respective holders may be modified by us only with the consent of holders of not less than a majority in aggregate principal amount of the outstanding debt securities of all series under the respective indenture affected by the modification, taken together as a class. But no modification that:

changes the amount of securities whose holders must consent to an amendment, supplement or waiver;

reduces the rate of or changes the interest payment time on any security or alters its redemption provisions (other than any alteration to any such section which would not materially adversely affect the legal rights of any holder under the indenture) or the price at which we are required to offer to purchase the securities;

reduces the principal or changes the maturity of any security or reduces the amount of, or postpones the date fixed for, the payment of any sinking fund or analogous obligation;

waives a default or event of default in the payment of the principal of or interest, if any, on any security (except a rescission of acceleration of the securities of any series by the holders of at least a majority in principal amount of the outstanding securities of that series and a waiver of the payment default that resulted from such acceleration);

makes the principal of or interest, if any, on any security payable in any currency other than that stated in the security;

makes any change with respect to holders' rights to receive principal and interest, certain modifications affecting shareholders or certain currency-related issues; or

waives a redemption payment with respect to any security or changes any of the provisions with respect to the redemption of any securities

will be effective against any holder without his consent. In addition, other terms as specified in subsequent filings may be modified without the consent of the holders.

Events of Default

Each indenture defines an event of default for the debt securities of any series as being any one of the following events:

default in any payment of interest when due which continues for 30 days;

default in any payment of principal or premium at maturity;

default in the deposit of any sinking fund payment when due;

default in the performance of any covenant in the debt securities or the applicable indenture which continues for 60 days after we receive notice of the default;

default under a bond, debenture, note or other evidence of indebtedness for borrowed money by us or our subsidiaries (to the extent we are directly responsible or liable therefor) having a principal amount in excess of a minimum amount set forth in the applicable subsequent filing, whether such indebtedness now exists or is hereafter created, which default shall have resulted in such indebtedness becoming or being declared due and payable prior to the date on which it would otherwise have become due and payable, without such acceleration having been rescinded or annulled or cured within 30 days after we receive notice of the default; and

events of bankruptcy, insolvency or reorganization.

An event of default of one series of debt securities does not necessarily constitute an event of default with respect to any other series of debt securities.

There may be such other or different events of default as described in an applicable subsequent filing with respect to any class or series of offered debt securities.

In case an event of default occurs and continues for the debt securities of any series, the applicable trustee or the holders of not less than 25% in aggregate principal amount of the debt securities then outstanding of that series may declare the principal and accrued but unpaid interest of the debt securities of that series to be due and payable. Any event of default for the debt securities of any series which has been cured may be waived by the holders of a majority in aggregate principal amount of the debt securities of that series then outstanding.

Each indenture requires us to file annually after debt securities are issued under that indenture with the applicable trustee a written statement signed by two of our officers as to the absence of material defaults under the terms of that indenture. Each indenture provides that the applicable trustee may withhold notice to the holders of any default if it considers it in the interest of the holders to do so, except notice of a default in payment of principal, premium or interest.

Subject to the duties of the trustee in case an event of default occurs and continues, each indenture provides that the trustee is under no obligation to exercise any of its rights or powers under that indenture at the request, order or direction of holders unless the holders have offered to the trustee reasonable indemnity. Subject to these provisions for indemnification and the rights of the trustee, each indenture provides that the holders of a majority in principal amount of the debt securities of any series then outstanding 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 as long as the exercise of that right does not conflict with any law or the indenture.

Defeasance and Discharge

The terms of each indenture provide us with the option to be discharged from any and all obligations in respect of the debt securities issued thereunder upon the deposit with the trustee, in trust, of money or United States government obligations, or both, which through the payment of interest and principal in accordance with their terms will provide money in an amount sufficient to pay any installment of principal, premium and interest on, and any mandatory sinking fund payments in respect of, the debt securities on the stated maturity of the payments in accordance with the terms of the debt securities and the indenture governing the debt securities. This right may only be exercised if, among other things, we have received from, or there has been published by, the United States Internal Revenue Service a ruling to the effect that such a discharge will not be deemed, or result in, a taxable event with respect to holders. This discharge would not apply to our obligations to register the transfer or exchange of debt securities, to replace stolen, lost or mutilated debt securities, to maintain paying agencies and hold moneys for payment in trust.

Defeasance of Certain Covenants

The terms of the debt securities provide us with the right not to comply with specified covenants and that specified events of default described in a subsequent filing will not apply. In order to exercise this right, we will be required to deposit with the trustee money or U.S. government obligations, or both, which through the payment of interest and principal will provide money in an amount sufficient to pay principal, premium, if any, and interest on, and any mandatory sinking fund payments in respect of, the debt securities on the stated maturity of such payments in accordance with the terms of the debt securities and the indenture governing such debt securities. We will also be required to deliver to the trustee an opinion of counsel to the effect that the deposit and related covenant defeasance should not cause the holders of such series to recognize income, gain or loss for United States federal income tax purposes.

A subsequent filing may further describe the provisions, if any, of any particular series of offered debt securities permitting a discharge defeasance.

Global Securities

The debt securities of a series may be issued in whole or in part in the form of one or more global securities that will be deposited with, or on behalf of, a depository identified in an applicable subsequent filing and registered in the name of the depository or a nominee for the depository. In such a case, one or more global securities will be issued in a denomination or aggregate denominations equal to the portion of the aggregate principal amount of outstanding debt securities of the series to be represented by the global security or securities. Unless and until it is exchanged in whole or in part for debt securities in definitive certificated form, a global security may not be transferred except as a whole by the depository for the global security to a nominee of the depository or by a nominee of the depository to the depository or another nominee of the depository or by the depository or any nominee to a successor depository for that series or a nominee of the successor depository and except in the circumstances described in an applicable subsequent filing.

We expect that the following provisions will apply to depository arrangements for any portion of a series of debt securities to be represented by a global security. Any additional or different terms of the depository arrangement will be described in an applicable subsequent filing.

Upon the issuance of any global security, and the deposit of that global security with or on behalf of the depository for the global security, the depository will credit, on its book-entry registration and transfer system, the principal amounts of the debt securities represented by that global security to the accounts of institutions that have accounts with the depository or its nominee. The accounts to be credited will be designated by the underwriters or agents engaging in the distribution of the debt securities or by us, if the debt securities are offered and sold directly by us. Ownership of beneficial interests in a global security will be limited to participating institutions or persons that may hold interests through such participating institutions. Ownership of beneficial interests by participating institutions in the global security will be shown on, and the transfer of the beneficial interests will be effected only through, records maintained by the depository for the global security or by its nominee. Ownership of beneficial interests in the global security by persons that hold through participating institutions will be shown on, and the transfer of the beneficial interests within the participating institutions will be effected only through, records maintained by those participating institutions. The laws of some jurisdictions may require that purchasers of securities take physical delivery of the securities in certificated form. The foregoing limitations and such laws may impair the ability to transfer beneficial interests in the global securities.

So long as the depository for a global security, or its nominee, is the registered owner of that global security, the depository or its nominee, as the case may be, will be considered the sole owner or holder of the debt securities represented by the global security for all purposes under the applicable indenture. Unless otherwise specified in an applicable subsequent filing and except as specified below, owners of beneficial interests in the global security will not be entitled to have debt securities of the series represented by the global security registered in their names, will not receive or be entitled to receive physical delivery of debt securities of the series in certificated form and will not be considered the holders thereof for any purposes under the indenture. Accordingly, each person owning a beneficial interest in the global security must rely on the procedures of the depository and, if such person is not a participating institution, on the procedures of the participating institution through which the person owns its interest, to exercise any rights of a holder under the indenture.

The depository may grant proxies and otherwise authorize participating institutions to give or take any request, demand, authorization, direction, notice, consent, waiver or other action which a holder is entitled to give or take under the applicable indenture. We understand that, under existing industry practices, if we request any action of holders or any owner of a beneficial interest in the global security desires to give any notice or take any action a holder is entitled to give or take under the applicable indenture, the depository would authorize the participating institutions to give the notice or take the action, and participating institutions would authorize beneficial owners owning through such participating institutions to give the notice or take the action or would otherwise act upon the instructions of beneficial owners owning through them.

Unless otherwise specified in applicable subsequent filings, payments of principal, premium and interest on debt securities represented by a global security registered in the name of a depository or its nominee will be made by us to the depository or its nominee, as the case may be, as the registered owner of the global security.

We expect that the depository for any debt securities represented by a global security, upon receipt of any payment of principal, premium or interest, will credit participating institutions' accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of the global security as shown on the records of the depository. We also expect that payments by participating institutions to owners of beneficial interests in the global security held through those participating institutions will be governed by standing instructions and customary practices, as is now the case with the securities held for the accounts of customers registered in street name, and will be the responsibility of those participating institutions. None of us, the trustees or any agent of ours or the trustees will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial interests in a global security, or for maintaining, supervising or reviewing any records relating to those beneficial interests.

Unless otherwise specified in the applicable subsequent filings, a global security of any series will be exchangeable for certificated debt securities of the same series only if:

the depository for such global securities notifies us that it is unwilling or unable to continue as depository or such depository ceases to be a clearing agency registered under the Exchange Act and, in either case, a successor depository is not appointed by us within 90 days after we receive the notice or become aware of the ineligibility;

we in our sole discretion determine that the global securities shall be exchangeable for certificated debt securities; or

there shall have occurred and be continuing an event of default under the applicable indenture with respect to the debt securities of that series.

Upon any exchange, owners of beneficial interests in the global security or securities will be entitled to physical delivery of individual debt securities in certificated form of like tenor and terms equal in principal amount to their beneficial interests, and to have the debt securities in certificated form registered in the names of the beneficial owners, which names are expected to be provided by the depository's relevant participating institutions to the applicable trustee.

In the event that the Depository Trust Company, or DTC, acts as depository for the global securities of any series, the global securities will be issued as fully registered securities registered in the name of Cede & Co., DTC's partnership nominee.

DTC, is a member of the U.S. Federal Reserve System, a limited-purpose trust company under New York State banking law and a registered clearing agency with the SEC. Established in 1973, DTC was created to reduce costs and provide clearing and settlement efficiencies by immobilizing securities and making "book-entry" changes to ownership of the securities. DTC provides securities movements for the net settlements of the National Securities Clearing Corporation, or NSCC, and settlement for institutional trades (which typically involve money and securities transfers between custodian banks and broker/dealers), as well as money market instruments.

DTC is a subsidiary of The Depository Trust & Clearing Company, or DTCC. DTCC is a holding company established in 1999 to combine DTC and NSCC. DTCC, through its subsidiaries, provides clearing, settlement and information services for equities, corporate and municipal bonds, government and mortgage backed securities, money market instruments and over the-counter derivatives. In addition, DTCC is a leading processor of mutual funds and insurance transactions, linking funds and carriers with their distribution networks. DTCC's customer base extends to thousands of companies within the global financial services industry. DTCC serves brokers, dealers, institutional investors, banks, trust companies, mutual fund companies, insurance carriers, hedge funds and other financial intermediaries – either directly or through correspondent relationships.

To facilitate subsequent transfers, the debt securities may be registered in the name of DTC's nominee, Cede & Co. The deposit of the debt securities with DTC and their registration in the name of Cede & Co. will effect no change in beneficial ownership. DTC has no knowledge of the actual beneficial owners of the debt securities. DTC's records reflect only the identity of the direct participating institutions to whose accounts debt securities are credited, which may or may not be the beneficial owners. The participating institutions remain responsible for keeping account of their holdings on behalf of their customers.

Delivery of notices and other communications by DTC to direct participating institutions, by direct participating institutions to indirect participating institutions, and by direct participating institutions and indirect participating institutions to beneficial owners of debt securities are governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect.

Neither DTC nor Cede & Co. consents or votes with respect to the debt securities. Under its usual procedures, DTC mails a proxy to the issuer as soon as possible after the record date. The proxy assigns Cede & Co.'s consenting or voting rights to those direct participating institution to whose accounts the debt securities are credited on the record date.

If applicable, redemption notices shall be sent to Cede & Co. If less than all of the debt securities of a series represented by global securities are being redeemed, DTC's practice is to determine by lot the amount of the interest of each direct participating institution in that issue to be redeemed.

To the extent that any debt securities provide for repayment or repurchase at the option of the holders thereof, a beneficial owner shall give notice of any option to elect to have its interest in the global security repaid by us, through its participating institution, to the applicable trustee, and shall effect delivery of the interest in a global security by causing the direct participating institution to transfer the direct participating institution's interest in the global security or securities representing the interest, on DTC's records, to the applicable trustee. The requirement for physical delivery of debt securities in connection with a demand for repayment or repurchase will be deemed satisfied when the ownership rights in the global security or securities representing the debt securities are transferred by direct participating institutions on DTC's records.

DTC may discontinue providing its services as securities depository for the debt securities at any time. Under such circumstances, in the event that a successor securities depository is not appointed, debt security certificates are required to be printed and delivered as described above.

We may decide to discontinue use of the system of book-entry transfers through the securities depository. In that event, debt security certificates will be printed and delivered as described above.

DTCC is industry-owned by its customers who are members of the financial community, such as banks, broker/dealers, mutual funds and other financial institutions. DTCC operates on an at-cost basis, returning excess revenue from transaction fees to its member firms. All services provided by DTC are regulated by the SEC.

The 2015 DTCC Board of Directors is composed of 19 directors serving one-year terms. Twelve directors are representatives of clearing agency participants, including international broker/dealers, custodian and clearing banks, and investment institutions; of these, two directors are designated by DTCC's preferred shareholders, NYSE Euronext and FINRA. Three directors are from non-participants. The remaining two are the chairman, and the president and the chief executive officer of DTCC. All of the Board members except those designated by the preferred shareholders are elected annually.

DESCRIPTION OF WARRANTS

We may issue warrants to purchase any of our debt or equity securities. Each series of warrants will be issued under a separate warrant agreement to be entered into between us and a warrant agent. The terms of any warrants to be issued and a description of the material provisions of the applicable warrant agreement will be set forth in the applicable prospectus supplement.

The applicable prospectus supplement will describe the following terms of any warrants in respect of which this prospectus is being delivered:

the title of such warrants;

the aggregate number of such warrants;

the price or prices at which such warrants will be issued;

the number and type of our securities purchasable upon exercise of such warrants;

the price at which our securities purchasable upon exercise of such warrants may be purchased;

the date on which the right to exercise such warrants shall commence and the date on which such right shall expire;

if applicable, the minimum or maximum amount of such warrants which may be exercised at any one time;

if applicable, the designation and terms of the securities with which such warrants are issued and the number of such warrants issued with each such security;

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

information with respect to book-entry procedures, if any;

if applicable, a discussion of any material United States federal income tax considerations; and

any other terms of such warrants, including terms, procedures and limitations relating to the exchange and exercise of such warrants.

DESCRIPTION OF PURCHASE CONTRACTS

We may issue purchase contracts for the purchase or sale of any of our debt or equity securities issued by us.

Each purchase contract will entitle the holder thereof to purchase or sell, and obligate us to sell or purchase, on specified dates, such securities, at a specified purchase price, which may be based on a formula, all as set forth in the applicable prospectus supplement. We may, however, satisfy our obligations, if any, with respect to any purchase contract by delivering the cash value of such purchase contract or the cash value of the securities otherwise deliverable, as set forth in the applicable prospectus supplement. The applicable prospectus supplement will also specify the methods by which the holders may purchase or sell such securities, and any acceleration, cancellation or termination provisions, provisions relating to U.S. federal income tax considerations, if any, or other provisions relating to the settlement of a purchase contract.

The purchase contracts may require us to make periodic payments to the holders thereof or vice versa, which payments may be deferred to the extent set forth in the applicable prospectus supplement, and those payments may be unsecured or prefunded on some basis. The purchase contracts may require the holders thereof to secure their obligations in a specified manner to be described in the applicable prospectus supplement. Alternatively, purchase contracts may require holders to satisfy their obligations thereunder when the purchase contracts are issued. Our obligation to settle such pre-paid purchase contracts on the relevant settlement date may constitute indebtedness. Accordingly, pre-paid purchase contracts will be issued under the senior indenture or the subordinated indenture.

The purchase contracts will be construed in accordance with and governed by the laws of the State of New York, without giving effect to any principles thereof relating to conflicts of law that would result in the application of the laws of any other jurisdiction.

DESCRIPTION OF RIGHTS

We may issue rights to purchase our equity securities. These rights may be issued independently or together with any other security offered by this prospectus and may or may not be transferable by the stockholder receiving the rights in the rights offering. In connection with any rights offering, we may enter into a standby underwriting agreement with one or more underwriters pursuant to which the underwriter will purchase any securities that remain unsubscribed for upon completion of the rights offering.

The applicable prospectus supplement relating to any rights will describe the terms of the offered rights, including, where applicable, the following:

the exercise price for the rights;

the number of rights issued to each stockholder;

the extent to which the rights are transferable;

any other terms of the rights, including terms, procedures and limitations relating to the exchange and exercise of the rights;

the amount of rights outstanding;

the extent to which the rights include an over-subscription privilege with respect to unsubscribed securities; and

the material terms of any standby underwriting arrangement entered into by us in connection with the rights offering.

Disclosure of Commission Position on Indemnification for Securities Act Liabilities

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers or persons controlling the registrant pursuant to the foregoing provisions, the registrant has been informed 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.
