RISK FACTORS

An investment in our securities involves substantial risks. In consultation with your own advisors, you should carefully consider, among other matters, the risk factors and other information we include or incorporate by reference in this prospectus supplement and the accompanying prospectus before deciding whether to invest in our securities. In particular, you should carefully consider, among other things, the factors described under the caption “Risk Factors” in Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2020, as may be updated by our subsequently-filed Quarterly Reports on Form 10-Q and Current Reports on Form 8-K. If any of the risks contained in or incorporated by reference into this prospectus supplement and the accompanying prospectus develop into actual events, our business, financial condition, liquidity, results of operations and prospects could be materially and adversely affected, the market price of our securities could decline, and you may lose all or part of your investment. Some statements in this prospectus supplement and the accompanying prospectus, and in the documents incorporated by reference into this prospectus supplement and the accompanying prospectus, including statements relating to the risk factors, constitute forward-looking statements. See the “Cautionary Note Regarding Forward-Looking Statements” section in this prospectus supplement and the accompanying prospectus.

Risks Related to This Offering

Our common stock has experienced and may continue to experience price and volume fluctuations, which could cause you to lose a significant portion of your investment.

Stock markets are subject to significant price and volume fluctuations that may be unrelated to the operating performance of particular companies, and accordingly the market price of our common stock may frequently and meaningfully change. The market prices and trading volume of our common stock have recently experienced, and may continue to experience, significant fluctuations, which could cause purchasers of our common stock to incur substantial losses. For example, during 2021 to August 20, 2021, the closing market price of our common stock has fluctuated from a low of $1.00 per share on April 20, 2021 to a high of $2.22 on February 9, 2021, with an intraday high of $2.33 per share on February 1, 2021 and an intraday low of $0.97 per share on April 20, 2021. The last reported sale price of our common stock on the NYSE American on August 20, 2021 was $1.08 per share. The daily trading volume in shares of our common stock has also experienced significant fluctuation. During 2021, through August 20, 2021, daily trading volume ranged from approximately 34,700 shares to 25,998,623 shares. We have not had any recent change in our financial condition or results of operations that we believe are consistent with recent fluctuations in our stock price or trading volume. Although we believe that the recent fluctuations in our stock price and trading volume reflect market and trading dynamics that appear to be unrelated to our underlying business, or to macro or industry fundamentals, we cannot be certain of the reasons for these fluctuations, nor can we predict how long these dynamics will last. These factors heighten the risk of an investment in our common stock, and the timing of your purchase of our common stock relative to fluctuations in its trading price may result in you losing all or a significant portion of your investment.

Significant fluctuations in the market price of our common stock may be the result of strong and substantially increased retail investor interest, including on social media and online forums. The market price and trading volume fluctuations and trading patterns we have experienced create several risks for investors, including the following:

We may continue to experience rapid and significant changes in our stock price and/or trading volume in the foreseeable future that may not coincide in timing with our disclosure of news or developments affecting us and our business. Accordingly, the market price of our shares of common stock may fluctuate dramatically, and may decline rapidly, regardless of any developments in our business. If the market price of our common stock declines and or trading volume is reduced, you may be unable to resell your shares at or above the price at which you acquired them.

There are also a variety of other factors, some of which are beyond our control, that could negatively affect the market price of our common stock or result in fluctuations in the price or trading volume of our common stock, including:

In the past, following periods of volatility in the market price of a company’s stock, class action securities litigation has often been instituted against such companies. Litigation may arise out of facts and circumstances, or disclosure relating thereto, that we do not currently regard as material. Such volatility may entice stockholders to challenge our disclosure, whether or not they are correct. Any litigation, if instituted against us, could result in substantial costs and diversion of management’s attention and resources, which would interfere with our ability to execute our business plan and otherwise materially adversely affect our business, financial condition and operating results.

You may experience immediate and substantial dilution.

If the offering price per share you pay in this offering exceeds the net tangible book value per share of our common stock, you will be immediately diluted to the extent of the difference between the amount you pay per share and the as-adjusted net tangible book value per share of our common stock after giving effect to this offering. To the extent that any options to purchase shares of our common stock are exercised or any outstanding restricted stock units vest and settle, and to the extent that we otherwise issue additional shares of our common stock, you may experience further dilution.

Our management will have broad discretion as to the use of the proceeds from this offering and may not use the proceeds effectively.

Because we have not designated the amount of net proceeds from this offering to be used for any particular purpose, our management will have broad discretion as to the application of the net proceeds from this offering and could use them for purposes other than those contemplated at the time of the offering. You will be relying on the judgment of our management regarding the application of these proceeds. Our management may use the net proceeds for corporate purposes that may not improve our financial condition or operating results, or enhance the market value of our common stock. If our management fails to apply these proceeds effectively, it may result, among other things, in unfavorable returns and uncertainty about our prospects, each of which could cause the price of our common stock to decline.

We do not expect to pay any dividends in the foreseeable future.

In the past, we have not paid dividends on our common stock and we do not currently intend to pay dividends on our common stock. We intend to retain our future earnings, if any, to fund the development and growth of our business. In addition, the terms of certain existing and any future debt agreements may preclude us from paying dividends. As a result, capital appreciation, if any, of our common stock may be your sole source of gain for the foreseeable future.

You may experience future dilution as a result of future equity offerings.

In order to raise additional capital, we may in the future offer additional shares of our common stock or other securities convertible into or exchangeable for our common stock. We may not be able to sell shares or other securities in any other offering at a price per share that is equal to or greater than the price per share paid by investors in this offering, and investors purchasing shares or other securities in the future could have rights superior to existing shareholders. The price per share at which we sell additional shares of our common stock or other securities convertible into or exchangeable for our common stock in future transactions may be higher or lower than the price per share in this offering. Future sales by us of our common stock or other securities convertible into or exchangeable for our common stock, as well as the possibility that we might issue such shares, could adversely affect the market price or increase the market price volatility of our common stock.

Our share ownership is highly concentrated.

As of August 12, 2021, our directors and officers beneficially own approximately 55.7% of our common stock and will continue to have significant influence over the outcome of all matters submitted to the stockholders for approval, including the election of our directors. In addition, certain of our directors and officers will have the right to acquire additional shares of our common stock upon exercise of conversion rights with respect to certain of our indebtedness held by them.

Future sales by our directors and officers of substantial amounts of our common stock, or the possibility that such sales could occur, could adversely affect the market price of our common stock.

As discussed above, our director and officers beneficially own a significant percentage or our common stock. Sales of common stock by our directors and officers, or the possibility that such sales could occur, could adversely affect the market price or increase the market price volatility of our common stock.

We are subject to the continued listing requirements of the NYSE American. If we are unable to comply with such requirements, our common stock would be delisted from the NYSE American, which would limit investors’ ability to effect transactions in our common stock and subject our common stock to additional trading restrictions.

Our common stock is currently listed on NYSE American. In order to maintain our listing, we must maintain certain share prices, financial and share distribution targets, including maintaining a minimum amount of stockholders’ equity and a minimum number of public shareholders. In addition to these objective standards, NYSE American may delist the securities of any issuer for other reasons involving the judgment of NYSE American. On June 10, 2020 we received written notification from NYSE American that we are not in compliance with the continued listing standard under Section 1003(a)(iii) of the NYSE American Company Guide (“Company Guide”), which requires a listed company to have stockholders’ equity of at least $6 million if it has reported losses from continuing operations and/or net losses in its five most recent fiscal years. In accordance with NYSE American requirements, we submitted a plan addressing how we intend to regain compliance with Section 1003(a)(iii) by December 10, 2021, the deadline for us to regain compliance.

On August 27, 2020, we received notice that our plan to regain compliance with Section 1003(a)(iii) of the Company Guide had been accepted and that we had been granted a plan period through December 10, 2021. As a result, the listing of our common stock on NYSE American is being continued during the plan period pursuant to an extension. However, during the plan period we will be subject to periodic review by NYSE Regulation staff, including quarterly monitoring, to determine if we are making progress consistent with the plan.

On December 9, 2020, we received an additional written notification from NYSE American that we are not in compliance with the continued listing standard set forth in Section 1003(a)(ii) of the Company Guide, which requires a listed company to have stockholders’ equity of at least $4 million if it has reported losses from continuing operations and/or net losses in three of its four most recent fiscal years.

On April 2, 2021, we received an additional written notification from NYSE American that we are not in compliance with the continued listing standard set forth in Section 1003(a)(i) of the Company Guide, which requires a listed company to have stockholders’ equity of at least $2 million if it has reported losses from continuing operations and/or net losses in two of its three most recent fiscal years.

If we are not in compliance with all of these continued listing standards by December 10, 2021, or if NYSE Regulation determines that we are not making sufficient progress consistent with our plan, delisting proceedings will be instituted against us, as appropriate.

Due largely to the continuing effects of the COVID-19 pandemic, we did not meet certain elements of the near-term milestones we had included as part of the compliance plan we submitted to the NYSE American. As a result, it is possible that NYSE Regulation will determine that we are not making sufficient progress consistent with our plan and may request that we submit a revised plan or may initiate delisting proceedings against us. We cannot assure you that we will make sufficient progress to regain compliance with these listing standards by December 10, 2021 under our initial plan or any revision we make to such plan or that NYSE Regulation will accept any revisions we propose to make to our initial plan, or that delisting proceedings may not be instituted against us based on our not meeting certain elements of the near-term milestones we had included as part of the compliance plan we submitted. If delisting proceedings are instituted against us, we would have the right to appeal any delisting determination.

If NYSE American delists our common stock from trading on the exchange and we are not able to list our securities on another national securities exchange, we expect our common stock would qualify to be quoted on an over-the-counter market. If this were to occur, we could experience a number of adverse consequences, including:

In addition, the National Securities Markets Improvement Act of 1996 generally preempts the states from regulating the sale of “covered securities.” Our common stock qualifies as “covered securities” because the shares of common stock are listed on NYSE American. If our common stock were no longer listed on NYSE American, our securities would not be “covered securities” and we would be subject to regulation in each state in which we offer our securities.

USE OF PROCEEDS

We intend to use the net proceeds from this offering, for general corporate purposes, including, without limitation, general working capital and the possible repayment of outstanding indebtedness. We have not determined the amount of proceeds to be used specifically for such purposes, and our management will have broad discretion in the use of proceeds from the sale of our shares. Although the foregoing represents our intentions based on our present plans and business conditions, the application of the proceeds from the offering and the amounts we actually expend for any purpose may vary significantly from the manner described above depending upon numerous factors, including assessments of potential market opportunities and competitive developments. Pending the use of the proceeds as described above, we may temporarily invest the proceeds in short-term, interest-bearing instruments or other investment-grade securities.

PLAN OF DISTRIBUTION

We are selling 200,000 shares of our common stock under this prospectus supplement directly to an institutional investor. We have not used an underwriter, placement agent or other party to assist us in connection with the sale of these shares.

We currently anticipate that the closing of the sale of our common stock under this prospectus supplement will take place on or about August 23, 2021. On the closing date, we will issue the shares of common stock to the purchaser and we will receive funds in the amount of the purchase price.

LEGAL MATTERS

The validity of the shares offered hereby will be passed upon for us by Stradley Ronon Stevens & Young, LLP, Philadelphia, Pennsylvania.

TABLE OF CONTENTS

ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement that we have filed with the SEC under the Securities Act of 1933, as amended, or the Securities Act, using a “shelf” registration process. Under this shelf registration statement, we are registering an unspecified amount of the securities described in this prospectus, and may sell any these securities in one or more offerings from time to time in the future, up to an aggregate offering amount of $10,000,000 (although pursuant to General Instruction I.B.6 of Form S-3 we may be limited to selling a lesser amount). This prospectus provides you with a general description of the securities we may offer and sell and is not meant to provide a complete description of each security. As a result, each time we sell securities, we will provide a prospectus supplement containing specific information about the terms of the offering, including specific amounts, prices and other terms of the securities being offered and other details related to the offering. The prospectus supplement may also add, update or change information contained in this prospectus.

RISK FACTORS

An investment in our securities involves substantial risks. In consultation with your own advisors, you should carefully consider, among other matters, the risk factors and other information we include or incorporate by reference in this prospectus and any prospectus supplement before deciding whether to invest in our securities. In particular, you should carefully consider, among other things, the factors described under the caption “Risk Factors” in Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2020, as may be updated by our subsequently-filed Quarterly Reports on Form 10-Q and Current Reports on Form 8-K. If any of the risks contained in or incorporated by reference into this prospectus or any prospectus supplement develop into actual events, our business, financial condition, liquidity, results of operations and prospects could be materially and adversely affected, the market price of our securities could decline, and you may lose all or part of your investment. Some statements in this prospectus and any prospectus supplement, and in the documents incorporated by reference into this prospectus or any prospectus supplement, including statements relating to the risk factors, constitute forward-looking statements. See the “Cautionary Note Regarding Forward-Looking Statements” section in this prospectus and any prospectus supplement.

USE OF PROCEEDS

Unless otherwise indicated in the applicable prospectus supplement, we expect to use the net proceeds from the sale of the offered securities for general corporate purposes. The prospectus supplement with respect to an offering may identify different or additional uses for the proceeds of that offering. In most cases, management will retain broad discretion over the allocation of net proceeds.

DESCRIPTION OF THE SECURITIES

This prospectus contains a summary of the common stock, preferred stock, warrants and units that we may offer and issue under this prospectus and any applicable prospectus supplement. The particular material terms of the securities offered by a prospectus supplement will be described in that prospectus supplement. If indicated in the applicable prospectus supplement, the terms of the offered securities may differ from the terms summarized below. The prospectus supplement will also contain information, where applicable, about material United States federal income tax considerations relating to the offered securities, and the securities exchange, if any, on which the offered securities will be listed. The descriptions herein and in the applicable prospectus supplement do not contain all of the information that you may find useful or that may be important to you. You should refer to the provisions of the actual documents whose terms are summarized herein and in the applicable prospectus supplement, because those documents, and not the summaries, define your rights as holders of the relevant securities.

DESCRIPTION OF COMMON STOCK

The following description, together with the additional information we may include in any applicable prospectus supplements, summarizes the material terms and provisions of the common stock that we may offer under this prospectus or any prospectus supplement. The following description provides a summary of the terms of our common stock, but does not purport to be complete and is subject to and qualified by reference to our certificate of incorporation and bylaws, as amended to date, which have been filed with or incorporated by reference in the registration statement of which this prospectus is a part.

The description below does not contain all of the information that you might find useful or that might be important to you. You should refer to the provisions of our certificate of incorporation and bylaws because they, and not the summaries, define the rights of holders of shares of our common stock. These documents are available as described under the heading “Where You Can Find More Information.”

General

Our certificate of incorporation authorizes the issuance of up to 25,000,000 shares of common stock and 5,000,000 shares of preferred stock. The rights and preferences of the preferred stock may be established from time to time by our board of directors. As of April 16, 2021, there were 11,960,505 shares of common stock issued and outstanding and no shares of preferred stock issued and outstanding.

Voting Rights

Except as otherwise required by law and except as provided by the terms of any other class or series of stock, holders of common stock have the exclusive power to vote on all matters presented to our stockholders, including the election of directors. Each holder of common stock is entitled to one vote per share, and each holder does not have cumulative voting rights. Accordingly, the holders of a majority of the shares of common stock entitled to vote in any election of directors can elect all of the directors standing for election if they so choose. All matters are decided by the vote of a majority in voting interest of the stockholders present in person or by proxy and voting at any meeting of the stockholders during which a quorum is present, except as otherwise provided in our certificate of incorporation, our bylaws or by applicable law.

Because our certificate of incorporation permits our board of directors to set the voting rights of preferred stock, it is possible that holders of one or more series of preferred stock issued in the future could have voting rights that might limit the effect of the voting rights of holders of common stock.

Dividend Rights; Liquidation Rights

Subject to preferences that may be applicable to any then outstanding preferred stock, holders of common stock are entitled to receive ratably those dividends, if any, as may be declared from time to time by the board of directors out of legally available funds. In addition, we may be party to one or more agreements, such as loan agreements and credit facilities, that will contractually limit our ability to pay dividends.

Because our certificate of incorporation permit our board of directors to set the dividend rights of preferred shares, it is possible that holders of one or more series of preferred shares issued in the future could have dividend rights that differ from those of the holders of our common stock. If the holders of a class or series of preferred stock is given dividend rights, the right of holders of preferred shares to receive dividends could have priority over the right of holders of our common stock to receive dividends.

We have followed and presently intend to continue following a policy of retaining earnings, if any. We have not historically declared or paid dividends on our common stock, and we do not expect to do so in the foreseeable future. Any future determination relating to our dividend policy will be made at the discretion of our board of directors and will depend on a number of factors, including our earnings and financial condition, liquidity and capital requirements, the general economic and regulatory climate, our ability to service any equity or debt obligations senior to our common stock, and other factors deemed relevant by our board of directors. 

In the event of our liquidation, dissolution or winding up, holders of common stock will be entitled to share ratably in the net assets legally available for distribution to stockholders after the payment of all of our debts and other liabilities and the satisfaction of any liquidation preference granted to the holders of any outstanding shares of preferred stock.

Redemption, Preemptive Rights and Repurchase Provisions

Holders of common stock have no preemptive or conversion rights or other subscription rights, and there are no redemption, repurchase or sinking fund provisions applicable to the common stock. Discretionary repurchases of our common stock may be subject to contractual prohibitions or limitations, including prohibitions or limitations included in loan agreements and credit facilities.

Potential Effects of Issuance of Preferred Stock

Under the terms of our certificate of incorporation, the board of directors is authorized, subject to any limitations prescribed by law, without stockholder approval, to issue shares of preferred stock in one or more series. Each such series of preferred stock will have such rights, preferences, privileges and restrictions, including voting rights, dividend rights, conversion rights, redemption privileges and liquidation preferences, as shall be determined by the board of directors.

The purpose of authorizing the board of directors to issue preferred stock and determine its rights and preferences is to eliminate delays associated with a stockholder vote on specific issuances. The issuance of preferred stock, while providing desirable flexibility in connection with a variety of corporate purposes, could have the effect of making it more difficult for a third party to acquire, or of discouraging a third party from acquiring, a majority of our outstanding voting stock.

The effects of issuing preferred stock could include one or more of the following:

Effect of Certain Provisions of our Certificate of Incorporation and Bylaws and the Delaware Anti-Takeover Statute

Some provisions of Delaware law and our certificate of incorporation and bylaws could make the following transactions more difficult:

It is possible that these provisions could make it more difficult to accomplish or could deter transactions that shareholders may otherwise consider to be in their best interest or in our best interest, including transactions which provide for payment of a premium over the market price for our shares.

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

Provisions of Our Governing Documents. Our certificate of incorporation and bylaws include provisions that may have the effects summarized above. These provisions:

Provisions of Applicable Law – Delaware Anti-Takeover Statute. We are subject to Section 203 of the Delaware General Corporation Law (“DGCL”). This law prohibits a publicly held Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years following the date that the stockholder became an “interested stockholder” unless:

Section 203 defines “business combination” to include:

In general, Section 203 of the DGCL defines an “interested stockholder” as an entity or person beneficially owning 15% or more of the outstanding voting stock of the corporation and any entity or person affiliated with or controlling or controlled by the entity or person.

Limitation of Liability and Indemnification

Section 145 of the DGCL allows us to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal or investigative (other than an action by or in the right of the corporation) by reason of the fact that the person is or was our director, officer, employee or agent, or is or was serving at our request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to our best interests, and, with respect to any criminal action or proceeding, had no reasonable cause to believe the person’s conduct was unlawful. Section 145 further allows us to indemnify any such person serving in any such capacity who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in our favor, by reason of the fact that the person is or was our director, officer, employee or agent, or is or was serving at our request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against expenses (including attorneys’ fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to our best interests and except that no indemnification is permitted in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to us, unless and only to the extent that the Delaware Court of Chancery or the court in which such action or suit was brought determines that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which such court deems proper.

Section 102(b)(7) of the DGCL permits us to include in our certificate of incorporation a provision eliminating or limiting the personal liability of a director to us or our stockholders for monetary damages for breach of fiduciary duty as a director, provided that such provision shall not eliminate or limit the liability of a director (i) for any breach of the director’s duty of loyalty, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL (relating to unlawful payment of dividends and unlawful stock purchase and redemption) or (iv) for any transaction from which the director derived an improper personal benefit.

Our certificate of incorporation provides that our directors shall not be liable to Blonder Tongue or our stockholders for monetary damages for breach of fiduciary duty as a director except to the extent that exculpation from liabilities is not permitted under the DGCL as in effect at the time such liability is determined. In addition, our certificate of incorporation and our bylaws each include provisions requiring us to indemnify directors and officers to the fullest extent permitted by the DGCL. Our certificate of incorporation and bylaws provide that any person made a party or threatened to be made a party to a threatened, pending or completed action, suit or proceeding by reason of the fact that such person is or was a director or officer of ours, is or was serving at our request as a director or officer of another corporation or enterprise, including service with respect to an employee benefit plan, shall be indemnified by us against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding to the fullest extent authorized from time to time by the DGCL. The rights of indemnification are not exclusive of any other rights to which those seeking indemnification may be entitled and shall continue as to a person who ceases to be a director, officer, employee or agent.

We have obtained director and officer liability insurance under which, subject to the limitations of such policies, coverage will be provided (a) to directors and officers against loss arising from claims made by reason of breach of fiduciary duty or other wrongful acts as a director or officer, including claims relating to public securities matters and (b) to us with respect to payments which we may make to our directors and officers pursuant to the indemnification provisions summarized above or otherwise as a matter of law.

We also have entered into indemnification agreements with our directors and officers. The indemnification agreements provide directors and officers with further indemnification to the maximum extent permitted by the DGCL.

We believe that the foregoing policies and provisions of our governing documents are necessary to attract and retain qualified officers and directors. Insofar as indemnification for liabilities arising under the Securities Act may be permitted with respect to our directors, officers or persons controlling us pursuant to the foregoing provisions, we have been informed that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Listing

Transfer Agent

DESCRIPTION OF PREFERRED STOCK

The following description, together with the additional information we may include in any applicable prospectus supplements, summarizes the material terms and provisions of the preferred stock that we may offer under this prospectus. While the terms summarized below will apply generally to any shares of preferred stock that we may offer, we will describe the particular terms of any series of preferred stock in more detail in the applicable prospectus supplement. If we indicate in the prospectus supplement, the terms of any shares of preferred stock offered under that prospectus supplement may differ from the terms described below. Specific certificates of designation will contain additional important terms and provisions and will be incorporated by reference as an exhibit to the registration statement that includes this prospectus. We urge you to read the applicable prospectus supplement and any related free writing prospectus, as well as the certificate of designation that contains the specific terms of the shares of any preferred stock we offer for sale.

General

Under the terms of our certificate of incorporation, our board of directors is authorized, subject to any limitations prescribed by law, without stockholder approval, to issue up to a maximum of 5,000,000 shares of preferred stock in one or more series, with such rights, preferences, privileges and restrictions, including voting rights, dividend rights, conversion rights, redemption privileges and liquidation preferences, as determined by the board of directors. As of the date of this prospectus, we do not have any shares of preferred stock outstanding.

The rights and privileges relating to any shares preferred stock we issue will be set forth in a certificate of designation. If we do issue any shares of preferred stock, we will make available the related certificate of designation. The terms included in the certificate of designation will provide additional detail and may be different than those summarized below. Because the certificate of designation will govern the shares of any preferred stock we issue, you should review the certificate of designation as that document, and not this summary, will define the rights and privileges of such shares.

In authorizing the issuance of any additional shares of our preferred stock, our board of directors may determine the following:

Terms

You should read the applicable prospectus supplement relating to the particular series of preferred stock being offered and issued and the related certificate of designation for specific terms of the shares of preferred stock of such series, including, where applicable:

When we issue shares of preferred stock, the shares will be fully paid and nonassessable, which means the full purchase price of the shares will have been paid and holders of the shares will not be assessed any additional monies for the shares. Unless the applicable prospectus supplement indicates otherwise, each series of the preferred stock will rank equally with any outstanding shares of our preferred stock and each other series of the preferred stock. Unless the applicable prospectus supplement states otherwise, the preferred stock will have no preemptive rights to subscribe for any additional securities which are issued by us, meaning, the holders of shares of preferred stock will have no right to buy any portion of the issued securities.

In addition, unless the applicable prospectus supplement indicates otherwise, we will have the right to “reopen” a previous issue of a series of preferred stock by issuing additional preferred stock of such series.

The transfer agent, registrar, dividend disbursing agent, calculation agent and redemption agent for shares of each series of preferred stock will be named in the prospectus supplement relating to such series.

Dividends

The holders of the preferred stock of each series will be entitled to receive cash dividends out of funds legally available, when, as and if, declared by our board of directors or a duly authorized committee of the board, at the rates and on the dates stated in the applicable prospectus supplement. These rates may be fixed, or variable, or both. If the dividend rate is variable, the applicable prospectus supplement will describe the formula used to determine the dividend rate for each dividend period. We will pay dividends to the holders of record as they appear on our stock books on the record dates determined by our board of directors or an authorized committee of our board.

Voting Rights

Holders of shares of preferred stock will have no voting rights, except as (i) otherwise stated in the applicable prospectus supplement, (ii) as otherwise stated in the certificate of designations establishing such series or (iii) as required by applicable law.

Redemption

A series of the preferred stock may be redeemable, in whole or in part, at our option, and may be subject to mandatory redemption under a sinking fund or otherwise as described in the applicable prospectus supplement. If a series of preferred stock is redeemable at our option, that applicable prospectus supplement will specify the conditions to such redemption and any restrictions, whether pursuant to the terms of the preferred stock or other securities or obligations of our, or pursuant to regulatory requirements, on our ability to redeem. If a series of preferred stock is subject to mandatory redemption, the applicable prospectus supplement will specify the number of shares that we will redeem, the time or times for such redemption, the redemption price per share and other obligations of ours in connection with the redemption. In each case, the applicable prospectus supplement will indicate whether the redemption price can be paid in cash or other property. Unless we default in the payment of the redemption price, dividends will cease to accrue after the redemption date on shares of preferred stock called for redemption and all rights of holders of such shares will terminate except for the right to receive the redemption price.

Conversion and Exchange

If any series of preferred stock we propose to offer and issue is convertible into or exchangeable for any other class or series of our capital stock or any other securities of ours, the applicable prospectus supplement relating to that series will describe the terms and conditions governing the conversions and exchanges.

Liquidation Rights

If we voluntarily or involuntarily liquidate, dissolve or wind up our business, the holders of shares of each series of preferred stock and any other securities that have rights equal to that series of preferred stock under these circumstances, will be entitled to receive out of our assets that are available for distribution to stockholders a distribution in the amount provided in certificate of designations and will receive such distributions (if any) before any distribution to holders of common stock or of any securities ranking junior to the series of preferred stock. If our assets are insufficient to pay all amounts to which holders of preferred stock are entitled, we will make no distribution on the preferred stock or on any other securities ranking equal to the preferred stock unless we make a pro rata distribution to those holders. After we pay the full amount of the liquidation distribution to which the holders are entitled, the holders will have no right or claim to any of our remaining assets.

Unless otherwise stated in the applicable prospectus supplement or the certificate of designations, neither the sale of all or any part of our property and business, nor our merger into or consolidation with any other corporation, nor the merger or consolidation of any other corporation with or into us, will be deemed to be a dissolution, liquidation or winding up.

DESCRIPTION OF WARRANTS

The following description, together with the additional information we may include in any applicable prospectus supplements, summarizes the material terms and provisions of the warrants that we may offer under this prospectus, and the related warrant agreements and warrant certificates. While the terms summarized below will apply generally to any warrants that we may offer, we will describe the particular terms of any warrants in more detail in the applicable prospectus supplement. If we indicate in the prospectus supplement, the terms of any warrants offered under that prospectus supplement may differ from the terms described below.

We urge you to read the applicable prospectus supplement and any related free writing prospectus, as well as the complete warrant agreement wan warrant certificate that contain the specific terms of the warrants we offer for sale.

General

We may issue warrants for the purchase of common stock or preferred stock. Warrants may be issued separately or together with common stock or preferred stock offered and issued by any prospectus supplement and may be attached to or separate from such common stock or preferred stock. Each series of warrants may be issued under a separate warrant agreement to be entered into between us and a bank or trust corporation, as warrant agent, all as set forth in the prospectus supplement relating to the particular issue of warrants, or a warrant agreement to be entered into between us and a purchaser of warrant and/or a warrant certificate containing specific terms of the warrant.

We will describe in the applicable prospectus supplement the terms of the particular warrants being offered and issued and the applicable warrant agreement, including, where applicable:

Warrant certificates may be exchanged for new warrant certificates of different denominations, may be presented for registration of transfer, and may be exercised at the corporate trust office of the warrant agent or any other office indicated in the applicable prospectus supplement. Prior to the exercise of any warrants to purchase common stock or preferred stock, holders of such warrants will not have any rights of holders of the common stock or preferred stock purchasable upon such exercise, including the right to receive payments of dividends, if any, on the common stock or preferred stock purchasable upon such exercise or to exercise any applicable right to vote.

Exercise of Warrants

Each warrant will entitle the holder to purchase such shares of common stock or preferred stock, as the case may be, at such exercise price as shall in each case be set forth in, or calculable from, the prospectus supplement relating to the warrants we propose to offer and issue. After the close of business on the expiration date of the warrants (or such later date to which such expiration date may be extended by us), unexercised warrants will become void. 

DESCRIPTION OF UNITS

The following description, together with the additional information we may include in any applicable prospectus supplements, summarizes the material terms and provisions of the units that we may offer under this prospectus and any related unit agreements that we may enter into or unit certificates that we may issue. While the terms summarized below will apply generally to any units that we may offer, we will describe the particular terms of any units in more detail in the applicable prospectus supplement. If we indicate in the prospectus supplement, the terms of any units offered under that prospectus supplement may differ from the terms described below.

We may issue units comprised of two or more of the other securities described in this prospectus in any combination and in one or more series. We may evidence each series of units by unit certificates that we will issue under a separate agreement. We may enter into unit agreements with a unit agent. Each unit agent will be a bank or trust company that we select. We will indicate the name and address of the unit agent, if any. in the applicable prospectus supplement relating to a particular series of units.

We will describe in the applicable prospectus supplement the terms of the particular units being offered and issued and the applicable unit agreement or unit certificate, including, where applicable:

The provisions described in this section, as well as those described under “Description of Common Stock,” and “Description of Preferred Stock” and “Description of Warrants” will apply to the securities included in each unit, to the extent relevant and as may be updated in any prospectus supplements.

PLAN OF DISTRIBUTION

We may sell the securities being offered hereby in one or more of the following ways from time to time:

We may directly solicit offers to purchase securities, or agents may be designated to solicit such offers. In the prospectus supplement relating to such offering, we will name any agent that could be viewed as an underwriter under the Securities Act and describe any commissions that we are obligated to pay to any such agent. Any such agent will be acting on a best efforts basis for the period of its appointment or, if indicated in the applicable prospectus supplement, on a firm commitment basis.

This prospectus may be used in connection with any offering of our securities through any of these methods or other methods described in the applicable prospectus supplement.

Each time that we use this prospectus to sell our securities, we will provide a prospectus supplement that describes the method of distribution of the securities and will set forth the specific terms of the offering of securities, including, as applicable:

If an underwriter is utilized in the sale of the securities being offered by this prospectus or any prospectus supplement, an underwriting agreement will be executed under which the underwriter will make resales of the securities to the public. In connection with the sale of the securities, we or the purchasers of securities for whom the underwriter may act as agent, may compensate the underwriter in the form of underwriting discounts or commissions. The underwriter may sell the securities to or through dealers, and those dealers may receive compensation in the form of discounts, concessions or commissions from the underwriter and/or commissions from the purchasers for which they may act as agent. Unless otherwise indicated in a prospectus supplement, an agent will be acting on a best efforts basis. If a dealer is utilized in the sale of the securities being offered by this prospectus or any prospectus supplement, the securities will be sold to the dealer, as principal. The dealer may then resell the securities to the public at varying prices to be determined by the dealer at the time of resale.

Any compensation paid to underwriters, dealers or agents in connection with the offering of the securities, and any discounts, concessions or commissions allowed by underwriters to participating dealers will be provided in the applicable prospectus supplement. Underwriters, dealers and agents participating in the distribution of the securities may be deemed to be underwriters within the meaning of the Securities Act, and any discounts and commissions received by them and any profit realized by them on resale of the securities may be deemed to be underwriting discounts and commissions. In addition, we may sell the securities directly to institutional investors or others who may be deemed to be underwriters within the meaning of the Securities Act with respect to any resales thereof.

We may enter into agreements to indemnify underwriters, agents and dealers against civil liabilities, including liabilities under the Securities Act, or to contribute to payments they may be required to make in respect thereof and to reimburse those persons for certain expenses.

Certain underwriters, agents and dealers, and their associates and affiliates, may be customers of, have borrowing relationships with, engage in other transactions with, or perform services, including investment banking services, for us or one or more of our respective affiliates in the ordinary course of business.

The sale and distribution of the securities may be effected from time to time in one or more transactions:

In order to facilitate the offering of the securities, any underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the securities or any other securities the prices of which may be used to determine payments on such securities. Specifically, any underwriters may over allot in connection with the offering, creating a short position for their own accounts. In addition, to cover overallotments or to stabilize the price of the securities or of any such other securities, the underwriters may bid for, and purchase, the securities or any such other securities in the open market. In any offering of the securities through a syndicate of underwriters, the underwriting syndicate also may reclaim selling concessions allowed to an underwriter or a dealer for distributing the securities in the offering if the syndicate repurchases previously distributed securities in transactions to cover syndicate short positions, in stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market price of the securities above independent market levels. Any such underwriters are not required to engage in these activities and may end any of these activities at any time.

We may engage in at the market offerings into an existing trading market in accordance with Rule 415(a)(4) under the Securities Act. In addition, 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 so 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 or others 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 named 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 and an applicable prospectus supplement. 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 underwriters who purchase securities from us for public offering and sale may make a market in those securities, but these underwriters will not be obligated to do so and may discontinue any market making at any time without notice. We cannot assure you that there will be a trading market for any securities, and, if a trading market for any securities does develop, we cannot assure you that such market will be liquid.

The specific terms of any lock-up provisions in respect of any given offering will be described in the applicable prospectus supplement.
