            Up to [•] Units
Each Consisting of One Share of Common Stock, One Class C Warrant to Purchase One Share of
Common Stock and One Class D Warrant to Purchase One Share of Common Stock

            Up to [•] Pre-Funded Units
Each Consisting of One Pre-Funded Warrant to Purchase One Share of Common Stock, One Class C
Warrant to Purchase One Share of Common Stock and One Class D Warrant to Purchase
One Share of Common Stock
            Up to [•] Shares of Common Stock Underlying the Class C Warrants, the Class D Warrants and the Pre-Funded Warrants

BIOLASE, Inc.

We are offering on a best efforts basis up to [•] units (“Units”), each Unit consisting of one share of common stock, par value $0.001 per share (“common stock”) of BIOLASE, Inc., one Class C warrant (each a “Class C Warrant” and collectively, the “Class C Warrants”) to purchase one share of common stock and one Class D warrant (each a “Class D Warrant”, and collectively, the “Class D Warrants”, and together with the Class C Warrants, the “Warrants”) to purchase one share of our common stock.

The assumed public offering price for each Unit is $[•], which represents the closing price of our common stock on the Nasdaq Capital Market on [•], 2024. The Units have no stand-alone rights and will not be certificated or issued as stand-alone securities. The common stock and Warrants are immediately separable and will be issued separately in this offering. The Class C Warrants and the Class D Warrants will not be exercisable until a stockholder approval as may be required by the applicable rules and regulations of the Nasdaq Capital Market (the “Warrant Stockholder Approval”) is obtained.

Each Class C Warrant offered hereby will become exercisable beginning on the date of the Warrant Stockholder Approval at an exercise price equal to [•]% of the public offering price per Unit in this offering, and will expire five years from the date of the Warrant Stockholder Approval. Each Class D Warrant offered hereby will become exercisable beginning on the date of the Warrant Stockholder Approval at an exercise price equal to [•]% of the public offering price per Unit in this offering, and will expire one year from the date of the Warrant Stockholder Approval.

Under the alternate cashless exercise option of the Class D Warrants, each holder of a Class D Warrant has the right to receive an aggregate number of shares equal to the product of (x) the aggregate number of shares of common stock that would be issuable upon a cash exercise of the Class D Warrant and (y) [•]. In addition, the Class C Warrants and Class D Warrants will include a provision that resets their respective exercise price in the event of a reverse split of our common stock, to a price equal to the lesser of (i) the then exercise price and (ii) lowest volume weighted average price (“VWAP”) during the period commencing five trading days immediately preceding and the five trading days commencing on the date we effect a reverse stock split in the future, and the number of shares issuable upon exercise will be proportionately adjusted such that the aggregate exercise price will remain unchanged. Further, subject to certain exceptions, the Class C Warrants will provide for an adjustment to the exercise price and number of shares underlying the Class C Warrants upon any issuance by us of our common stock or common stock equivalents at a price per share that is less than the exercise price of the Class C Warrants such that the aggregate exercise price will remain unchanged.

In the event that we are unable to obtain the Warrant Stockholder Approval, the Warrants will not be exercisable and therefore may have no value. See the Risk Factor on page 10 relating to the Class C Warrants and Class D Warrants and Warrant Stockholder Approval, and see the section entitled “Warrant Stockholder Approval” on page 39 for additional details regarding the Warrant Stockholder Approval.

We are also offering to those purchasers, if any, whose purchase of Units in this offering would otherwise result in the purchaser, together with its affiliates and related parties, beneficially owning more than 4.99% of our outstanding common stock immediately following the consummation of this offering, the opportunity to purchase, if they so choose pre-funded units (“Pre-Funded Units”) in lieu of the Units that would otherwise result in ownership in excess of 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding common stock, with each Pre-Funded Unit consisting of one pre-funded warrant to purchase one share of our common stock (each, a “Pre-Funded Warrant”), a Class C Warrant and a Class D Warrant. The purchase price of each Pre-Funded Unit will equal the price per Unit, minus $0.001, and the exercise price of each Pre-Funded Warrant included in the Pre-Funded Unit will be $0.001 per share of our common stock.

The Pre-Funded Units have no stand-alone rights and will not be certificated or issued as stand-alone securities. The Pre-Funded Warrants and Warrants can only be purchased together but are immediately separable and will be issued separately in this offering. There can be no assurance that we will sell any of the Pre-Funded Units being offered. The Pre-Funded Warrants offered hereby will be immediately exercisable and may be exercised at any time until exercised in full.

This prospectus also includes the shares of common stock issuable upon exercise of the Class C Warrants, the Class D Warrants, and the Pre-Funded Warrants. We refer to the shares of our common stock, the Warrants, the Pre-Funded Warrants and the shares of our common stock issued or issuable upon exercise of the Warrants and Pre-Funded Warrants, collectively, as the securities.

Because this is a best efforts offering, the placement agent does not have an obligation to purchase any securities, and, as a result, there is a possibility that we may not be able to sell the securities. We expect that the offering will end one trading day after we first enter into a securities purchase agreement relating to the offering and the offering will settle delivery versus payment (“DVP”)/receipt versus payment (“RVP”). Accordingly, we and the placement agent have not made any arrangements to place investor funds in an escrow account or trust account since the placement agent will not receive investor funds in connection with the sale of the securities offered hereunder.

We have engaged Maxim Group LLC (the “placement agent”) to act as our placement agent in connection with this offering. The placement agent has agreed to use its reasonable best efforts to arrange for the sale of the securities offered by this prospectus. The placement agent is not purchasing or selling any of the securities we are offering and the placement agent is not required to arrange the purchase or sale of any specific number or dollar amount of securities. We have agreed to pay to the placement agent the placement agent fees set forth in the table below, which assumes that we sell all of the securities offered by this prospectus. There is no arrangement for funds to be received in escrow, trust or similar arrangement. We will bear all costs associated with the offering. See “Plan of Distribution” on page 49 of this prospectus for more information regarding these arrangements.

Our common stock is traded on the Nasdaq Capital Market under the symbol “BIOL.” On May 31, 2024, the last reported sale price for our common stock on the Nasdaq Capital Market was $0.1708 per share. There is no established trading market for the Pre-Funded Warrants or the Warrants and we do not expect a market to develop. In addition, we do not intend to apply to list the Pre-Funded Warrants or the Warrants on the Nasdaq Capital Market or any other national securities exchange or any other nationally recognized trading system.

The actual public offering price per Unit and the actual public offering price per Pre-Funded Unit will be determined between us, the placement agent and investors in this offering based on market conditions at the time of pricing and may be at a discount to the current market price of our common stock. Therefore, the recent market price used throughout this prospectus may not be indicative of the final offering price.

Investing in our securities involves substantial risks. Please read carefully the section entitled “Risk Factors” beginning on page 10 of this prospectus, as well as the other information included or incorporated by reference in this prospectus, before buying any of our securities.

Our business, financial condition, results of operations and prospects may have changed since those dates.

We urge you to carefully read this prospectus, together with the information incorporated herein by reference as described under the heading “Where You Can Find More Information.”

Persons who come into possession of this prospectus and any applicable free writing prospectus in jurisdictions outside the United States are required to inform themselves about and to observe any restrictions as to this offering and the distribution of this prospectus and any such free writing prospectus applicable to that jurisdiction. See “Plan of Distribution” for additional information on these restrictions.

INDUSTRY AND MARKET DATA

Market data and certain industry data and forecasts used throughout this prospectus were obtained from sources we believe to be reliable, including market research databases, publicly available information, reports of governmental agencies and industry publications and surveys. We have relied on certain data from third-party sources, including internal surveys, industry forecasts and market research, which we believe to be reliable based on our management’s knowledge of the industry. Forecasts are particularly likely to be inaccurate, especially over long periods of time. In addition, we do not necessarily know what assumptions regarding general economic growth were used in preparing the third-party forecasts we cite. Statements as to our market position are based on the most currently available data. While we are not aware of any misstatements regarding the industry data presented in this prospectus, our estimates involve risks and uncertainties and are subject to change based on various factors, including those discussed under the heading “Risk Factors” in this prospectus.

RISK FACTORS

Investing in our securities involves a high degree of risk. You should carefully consider the risks described below and all of the information contained or incorporated by reference in this prospectus, including the risk factors described in our Form 10-K, our Form 10-Q and any subsequent Quarterly Reports on Form 10-Q, and all other information contained or incorporated by reference into this prospectus before deciding whether to purchase the securities offered hereby. Our business, financial condition, results of operations and prospects could be materially and adversely affected by these risks.

Risks Related to This Offering

Our management will have broad discretion over the use of the net proceeds from this offering, you may not agree with how we use the proceeds and the proceeds may not be invested successfully.

Our management will have broad discretion as to the use of the net proceeds from this offering and could use them for purposes other than those contemplated at the time of commencement of this offering. Accordingly, you will be relying on the judgment of our management regarding the use of these net proceeds, and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used appropriately. It is possible that, pending their use, we may invest the net proceeds in a way that does not yield a favorable, or any, return for us. The failure of our management to use such funds effectively could have a material adverse effect on our business, financial condition, operating results and cash flows.

You may experience immediate and substantial dilution in the net tangible book value per share of the common stock included as part of the Units or that may be issued upon the exercise of any Pre-Funded Warrants included as part of the Pre-Funded Units.

If the price per share of our common stock being offered as part of the Units or that may be issued upon the exercise of any Pre-Funded Warrants included as part of the Pre-Funded Units is higher than the net tangible book value per share of our common stock, you will suffer immediate and substantial dilution in the net tangible book value of the common stock you purchase in this offering or the common stock underlying the Pre-Funded Warrants you purchase in this offering. See the section entitled “Dilution” below for a more detailed discussion of the dilution you will incur if you invest in this offering.

You may experience future dilution as a result of future equity offerings and other issuances of our common stock or other securities. In addition, this offering and future equity offerings and other issuances of our common stock or other securities may adversely affect our common stock price.

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 at prices that may not be the same as the price per Unit in this offering. 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 Unit paid by the investor in this offering, and investors purchasing shares or other securities in the future could have rights superior to existing stockholders. The price per share at which we sell additional shares of our common stock or securities convertible into common stock in future transactions may be higher or lower than the price per Unit in this offering. You will incur dilution upon exercise of any outstanding stock options, warrants or upon the issuance of shares of common stock under our stock incentive programs. In addition, the sale of securities in this offering, the conversion of the Series H Convertible Preferred Stock and Series J Convertible Preferred Stock into common stock and any future sales of a substantial number of shares of our common stock in the public market, or the perception that such sales may occur, could adversely affect the price of our common stock. As of March 31, 2024, approximately 62,000 shares of common stock were reserved for issuance under our equity incentive plans, approximately 300 of which were subject to options outstanding, 58,000 of which were subject to restricted stock units outstanding or expected to be issued as of that date, 200 stock appreciation rights outstanding and 3,500 phantom restricted stock units outstanding or expected to be issued as of that date. In addition, as of March 31, 2024, approximately 1.3 million shares of our common stock were subject to warrants at a weighted-average exercise price of $36.82 per share. To the extent that outstanding warrants or options are exercised or the convertible preferred stock is converted, our existing stockholders could experience dilution. We rely heavily on equity awards to motivate current employees and to attract new employees. The grant of future equity awards by us to our employees and other service providers could further dilute our stockholders’ interests in the Company.

We cannot predict the effect, if any, that market sales of those shares of common stock or the availability of those shares for sale will have on the market price of our common stock.

This is a best efforts offering, no minimum amount of securities is required to be sold, and we may not raise the amount of capital we believe is required for our business plans.

The placement agent has agreed to use its reasonable best efforts to solicit offers to purchase the securities in this offering. The placement agent has no obligation to buy any of the securities from us or to arrange for the purchase or sale of any specific number or dollar amount of the securities. There is no required minimum number of securities that must be sold as a condition to completion of this offering. Because there is no minimum offering amount required as a condition to the closing of this offering, the actual offering amount, placement agent fees and proceeds to us are not presently determinable and may be substantially less than the maximum amounts set forth herein. We may sell fewer than all of the securities offered hereby, which may significantly reduce the amount of proceeds received by us, and investors in this offering will not receive a refund in the event that we do not sell an amount of securities sufficient to support our continued operations. Thus, we may not raise the amount of capital we believe is required for our operations and may need to raise additional funds. Such additional fundraises may not be available or available on terms acceptable to us.

We need to raise capital in this offering to support our operations. If we are unable to raise capital in this offering, our financial position will be materially adversely impacted.

We have historically experienced losses from operations. For the three months ended March 31, 2024, we had a net loss of approximately $6.5 million. From our inception through March 31, 2024, we had an accumulated deficit of approximately $323.3 million. We believe that current cash on hand, prior to the receipt of any proceeds from this offering, is not sufficient to fund operations beyond twelve months following the closing date of this offering. If we were to receive net proceeds of $[•] million from this offering, we believe that the net proceeds from this offering, together with our existing cash and cash equivalents, will meet our capital needs into [•]. If we receive 50% of the foregoing net proceeds, or $[•] million, in this offering, we believe that the net proceeds from this offering, together with our existing cash and cash equivalents will then meet our capital needs through the end of [•]. In addition, the report of our independent registered public accounting firm on our consolidated financial statements for the year ended December 31, 2023 contains explanatory language raising substantial doubt about our ability to continue as a going concern. In order for us to continue operations beyond the 12 months following the closing of this offering and be able to discharge our liabilities and commitments in the normal course of business, we must increase sales of our products, control or potentially reduce expenses and establish profitable operations in order to generate cash from operations or obtain additional funds when needed. We have no additional committed sources of capital and may find it difficult to raise money on terms favorable to us or at all. The failure to obtain sufficient capital to support our operations could have a material adverse effect on our business, financial condition and results of operations.

Purchasers who purchase our securities in this offering pursuant to a securities purchase agreement may have rights not available to purchasers that purchase without the benefit of a securities purchase agreement.

In addition to rights and remedies available to all purchasers in this offering under federal securities and state law, the purchasers that enter into a securities purchase agreement will also be able to bring claims of breach of contract against us. The ability to pursue a claim for breach of contract provides those investors with the means to enforce the covenants uniquely available to them under the securities purchase agreement.

There is no public market for the Warrants or Pre-Funded Warrants.

There is no established public trading market for the Warrants or Pre-Funded Warrants offered hereby, and we do not expect a market to develop. In addition, we do not intend to apply to list the Warrants or Pre-Funded Warrants on any national securities exchange or other nationally recognized trading system, including Nasdaq. Without an active market, the liquidity of those securities will be limited.

The Warrants in this offering are speculative in nature.

Following this offering, the market value of the Warrants, if any, is uncertain and there can be no assurance that the market value of the Warrants will equal or exceed their imputed public offering price. In the event that our common stock price does not exceed the exercise price of the Warrants during the period when such Warrants are exercisable, such Warrants may not have any value. Furthermore, if Warrant Stockholder Approval is not obtained, the Warrants will not be exercisable. Furthermore, each Class C Warrant will expire five years after the date we obtain Warrant Stockholder Approval and each Class D Warrant will expire one year after the date we obtain Warrant Stockholder Approval.

Holders of the Warrants and Pre-Funded Warrants will not have rights of holders of our shares of common stock until such Warrants and Pre-Funded Warrants are exercised.

The Warrants and Pre-Funded Warrants in this offering do not confer any rights of share ownership on their holders, but rather merely represent the right to acquire shares of our common stock at a fixed price. Until holders of Warrants and Pre-Funded Warrants acquire shares of our common stock upon exercise of the Warrants and Pre-Funded Warrants, as applicable, holders of Warrants and Pre-Funded Warrants will have no rights with respect to our shares of common stock underlying such Warrants and Pre-Funded Warrants.

Provisions of the Warrants and Pre-Funded Warrants offered by this prospectus could discourage an acquisition of us by a third party.

In addition to the discussion of the provisions of our Certificate of Incorporation, certain provisions of the Warrants and Pre-Funded Warrants offered by this prospectus could make it more difficult or expensive for a third party to acquire us. Such Warrants and Pre-Funded Warrants prohibit us from engaging in certain transactions constituting “fundamental transactions” unless, among other things, the surviving entity assumes our obligations under the Warrants and Pre-Funded Warrants. Further, the Warrants and Pre-Funded Warrants provide that, in the event of certain transactions constituting “fundamental transactions,” with some exception, holders of such the Warrants and Pre-Funded Warrants will have the right, at their option, to require us to repurchase such the Warrants and Pre-Funded Warrants at a price described in the Warrants and Pre-Funded Warrants. These and other provisions of the Warrants and Pre-Funded Warrants offered by this prospectus could prevent or deter a third party from acquiring us even where the acquisition could be beneficial to you.

The Warrants may not have any value.

The Class C Warrants will have an exercise price equal to [•]% of the public offering price per Unit in this offering and the Class D Warrants will have an exercise price equal to [•]% of the public offering price per Unit in this offering. The Class C Warrants will expire five years from the date of Warrant Stockholder Approval and the Class D Warrants will expire one year from the date of Warrant Stockholder Approval. In the event our common stock price does not exceed the exercise price of the Warrants during the period when the Warrants are exercisable, the Warrants may not have any value.

Stockholders may suffer substantial dilution if certain provisions in the Warrants are utilized.

If the Class D Warrants are exercised by way of an alternative cashless exercise, assuming receipt of Warrant Stockholder Approval, such exercising holder will receive three shares of our common stock for each Class D Warrant they exercise, without any cash payment to us.

In addition, and subject to certain exemptions, if we sell, enter into an agreement to sell, or grant any option to purchase, or sell, enter into an agreement to sell, or grant any right to reprice (excluding Exempt Issuances, as defined in the placement agency agreement), or otherwise dispose of or issue (or announce any offer, sale, grant or any option to purchase or other disposition) any shares of common stock, at an effective price per share less than the exercise price of the Class C Warrants then in effect, the exercise price of the Class C Warrants will be reduced to the lower of such price or the lowest VWAP during the five consecutive trading days immediately following such dilutive issuance or announcement thereof; provided that such price is subject to a Floor Price, and the number of shares issuable upon exercise will be proportionately adjusted such that the aggregate exercise price will remain unchanged.

If any of the above provisions in the Warrants are utilized, our stockholders may suffer substantial dilution.

We will likely not receive any additional funds upon the exercise of the Class D Warrants.

The Class D Warrants may be exercised by way of an alternative cashless exercise, in which case the holder would not pay a cash purchase price upon exercise, but instead would receive upon such exercise the number of shares equal to the number of Class D Warrants being exercised multiplied by [•]. Accordingly, we will likely not receive any additional funds upon the exercise of the Class D Warrants.

The exercisability of the Warrants is contingent upon us obtaining the Warrant Stockholder Approval. If we do not obtain such Warrant Stockholder Approval, the Warrants may never become exercisable.

The Warrants are not immediately exercisable, as their exercisability is contingent upon us obtaining Warrant Stockholder Approval. The Warrants will become exercisable upon Warrant Stockholder Approval and will expire on the five-year anniversary of such date with respect to the Class C Warrants, and on the one-year anniversary of such date with respect to the Class D Warrants. While we intend to promptly seek Warrant Stockholder Approval for these mechanisms, there is no guarantee that it will ever be obtained. In the event that we cannot obtain Warrant Stockholder Approval, the Warrants may never become exercisable. If we are unable to obtain the Warrant Stockholder Approval, the Warrants will have no value.

We have agreed to hold a special meeting of stockholders (which may also be at the annual meeting of stockholders) at the earliest practicable date after the date hereof, but in no event later than ninety days after the closing of the offering, in order to obtain Warrant Stockholder Approval. There is no guarantee we will be able to hold a special meeting within this timeframe, or at all.

Risks Related to Our Financial Position

Due to our accumulated deficit, recurring and negative cash flow from operations for the year ended December 31, 2023 and the quarter ended March 31, 2024, there is substantial doubt about our ability to continue as a going concern.

We incurred losses from operations and used cash in operating activities for the three months ended March 31, 2024 and for the years ended December 31, 2023 and 2022. Our audited consolidated financial statements for the year ended December 31, 2023 were prepared on a going concern basis in accordance with generally accepted accounting principles in the United States. The going concern basis assumes that we will continue in operation for the 12 months following the closing date of this offering and will be able to realize our assets and discharge our liabilities and commitments in the normal course of business. Thus, our consolidated financial statements do not include any adjustments that might be necessary if we are unable to continue as a going concern. Our recurring losses, negative cash flow, need for additional capital, and the uncertainties surrounding our ability to raise such capital raise substantial doubt about our ability to continue as a going concern. For us to continue operations beyond the 12 months following the closing date of this offering and be able to discharge our liabilities and commitments in the normal course of business, we must sell our products directly to end-users and through distributors, establish profitable operations through increased sales, decrease expenses, generate cash from operations or raise additional funds when needed. Our goal is to improve our financial condition and ultimately improve our financial results by increasing revenues through expanding awareness of the benefits of our dental lasers among dental specialists and general practitioners and reducing expenses. However, if we are unable to do so on a timely basis, we will be required to seek additional capital. In that event, we would seek additional funds through various financing sources, including the sale of our equity and debt securities, however, there can be no guarantees that such funds will be available on commercially reasonable terms, if at all. If we are unable to raise additional capital in amounts required, increase sales or reduce expenses, we will be unable to continue to fund our operations, develop our products, realize value from our assets, and discharge our liabilities in the normal course of business. If we become unable to continue as a going concern, we could have to liquidate our assets, and potentially realize significantly less than the values at which they are carried on our financial statements, and stockholders could lose all or part of their investment in our common stock. The report of our independent registered public accounting firm, Macias Gini & O’Connell LLP, included in our Form 10-K contains an explanatory paragraph regarding our ability to continue as a going concern.

We have experienced net losses for each of the quarter ended March 31, 2024 and the past three years, and we could experience additional losses and have difficulty achieving profitability in the future.

We had an accumulated deficit of $323.3 million as of March 31, 2024 and an accumulated deficit of $316.8 million as of December 31, 2023. We recorded net losses of $20.6 million and $28.6 million for the years ended December 31, 2023 and 2022, respectively, and net losses of $6.5 million and $5.8 million for the three months ended March 31, 2024 and 2023, respectively. In order to achieve profitability, we must increase net revenue through new sales and control our costs. Failure to increase our net revenue and decrease our costs could cause our stock price to decline and could have a material adverse effect on our business, financial condition, and results of operations.

Failure to meet covenants in the credit agreements with our debt agreements could result in acceleration of our payment obligations thereunder, and we may not be able to find alternative financing.

Under the Credit Agreement dated November 9, 2018, as amended from time to time, between BIOLASE, Inc. and SWK Funding LLC (“SWK”), we are required to maintain a specified amount of consolidated unencumbered liquid assets as of the end of each fiscal quarter, and, if we fall below those levels, generate minimum levels of revenue as of the end of each period specified in the Credit Agreement and maintain specified levels of consolidated EBITDA as of the end of each period specified in the Credit Agreement. Our ability to comply with these covenants may be affected by factors beyond our control.

If we fail to comply with the covenants contained in the Credit Agreement or if the Required Lenders (as defined in the Credit Agreement) contend that we have failed to comply with these covenants or any other restrictions, it could result in an event of default under the Credit Agreement, which would permit or, in certain events, require SWK to declare all amounts outstanding thereunder to be immediately due and payable. There can be no assurances that we will be able to repay all such amounts or able to find alternative financing in an event of a default. Even if alternative financing is available in an event of a default under the Credit Agreement, it may be on unfavorable terms, and the interest rate charged on any new borrowings could be substantially higher than the interest rate under the Credit Agreement, thus adversely affecting cash flows, results of operations, and ultimately, our ability to meet operating cash flow requirements.

The restrictive covenants in the Credit Agreement and BIOLASE’s obligation to make debt payments under the Credit Agreement may limit our operating and financial flexibility and may adversely affect the Company’s business, financial condition and results of operations.

The Credit Agreement imposes operating and financial restrictions and covenants, which may limit or prohibit our ability to, among other things:

•        incur additional indebtedness;

•        make investments, including acquisitions;

•        create liens;

•        make dividends, distributions or other restricted payments;

•        effect affiliate transactions;

•        enter into mergers, divisions, consolidations or sales of substantially all of our or our subsidiaries’ assets;

•        change business activities and issue equity interests; or

•        sell material assets (without using the proceeds thereof to repay the obligations under the Credit Agreement).

In addition, we are required to comply with certain financial covenants under the Credit Agreement as described above.

Such restrictive covenants in the Credit Agreement and our repayment obligations under the Credit Agreement could have adverse consequences to us, including:

•        limiting our ability to use cash;

•        limiting our flexibility in operating our business and planning for, or reacting to, changes in our business and our industry;

•        requiring the dedication of a substantial portion of any cash flow from operations to the payment of principal of, and interests on, the indebtedness, thereby reducing the availability of such cash flow to fund our operations, working capital, capital expenditures, future business opportunities and other general corporate purposes;

•        restricting us from making strategic acquisitions or causing us to make non-strategic divestitures;

•        limiting our ability to obtain additional financing;

•        limiting our ability to adjust to changing market conditions; and

•        placing us at a competitive disadvantage relative to our competitors who are less highly leveraged.

If we fail to comply with the terms of the Credit Agreement and there is an event of default, the creditor(s) may foreclose upon the assets securing our obligations thereunder.

To secure the performance of our obligations under the Credit Agreement, we granted SWK security interests in substantially all of the assets of BIOLASE and certain of our foreign and domestic subsidiaries. Our failure to comply with the terms of the Credit Agreement could result in an event of default thereunder. In that event, SWK will have the option to (and, in certain circumstances, will have the obligation to) foreclose on the assets of BIOLASE and certain of our subsidiaries pledged as collateral under the Credit Agreement or the other documents executed in connection with the Credit Agreement. The foreclosure on the Company’s assets could severely and negatively impact our business, financial condition, and results of operations.

Our ability to meet our redemption obligations under the existing convertible redeemable preferred stock depends on our earnings and cash flows, and we may not have sufficient funds to redeem such shares of preferred stock.

As of March 31, 2024, 15,821 and 5,000 shares of Series J Convertible Preferred Stock and Series H Convertible Preferred Stock were outstanding and redeemable by us on September 13, 2024 and May 24, 2025, respectively. No assurances can be given that we will be successful in making the required payments to the holders of the Series J Convertible Preferred Stock and/or the Series H Convertible Preferred Stock, or that we will be able to comply with the financial or other covenants contained in the Certificates of Designations for the Series J Convertible Preferred Stock and Series H Convertible Preferred Stock. If we are unable to make the required cash payments or otherwise comply with the Certificates of Designations due to insufficient funds, dividends will accrue on such preferred stock, the holders of such shares of preferred stock could foreclose against our assets, and/or we could be forced into bankruptcy or liquidation.

Risks Related to Our Failure to Comply with Nasdaq Listing Rules

Failure to meet Nasdaq’s continued listing requirements could result in the delisting of our common stock, negatively impact the price of our common stock and negatively impact our ability to raise additional capital.

On January 11, 2023, we received a deficiency letter from the Staff of the Nasdaq Stock Market (“Nasdaq”) notifying us that, for the last 30 consecutive business days, ending on January 10, 2023, the bid price for our common stock had closed below the minimum $1.00 per share requirement for continued inclusion on the Nasdaq Capital Market pursuant to Nasdaq Listing Rule 5550(a)(2) (the “Bid Price Rule”). In accordance with Nasdaq rules, we were provided an initial period of 180 calendar days, or until July 10, 2023, to regain compliance with the Bid Price Rule.

On June 8, 2023, we were notified by the Staff of Nasdaq that we did not meet the minimum closing bid price requirement of $1.00 for continued listing, as set forth in the Bid Price Rule, as the Staff had determined that as of June 8, 2023, our common stock had a closing bid price of $0.10 or less for ten consecutive trading days, from May 24, 2023 through June 7, 2023. As such, the Staff had determined to delist our common stock from the Nasdaq Capital Market and to suspend trading of our common stock at the opening of business on June 20, 2023, and file a Form 25-NSE with the SEC. We timely requested a hearing to appeal this determination, which stayed the suspension of our common stock pending the decision from a Nasdaq Hearings Panel (the “Panel”).

We subsequently requested the Panel grant us a temporary exception to regain compliance with the Bid Price Rule. On July 5, 2023, the Panel granted us an exception until August 11, 2023 to demonstrate bid price compliance subject to us taking the following actions: (i) on July 20, 2023, we obtain stockholder approval for a reverse stock split at a ratio that

is sufficient to regain and maintain long term compliance with the Bid Price Rule; (ii) on or before July 31, 2023, we effect a reverse stock split and, thereafter, maintain a $1.00 closing bid price for a minimum of ten consecutive business days; and (iii) on August 11, 2023, we demonstrated compliance with the Bid Price Rule, by evidencing a closing bid price of $1.00 or more per share for a minimum of ten consecutive trading sessions.

On July 20, 2023, we held a special meeting of our stockholders where the stockholders approved an amendment to our Certificate of Incorporation to effect a reverse stock split of our common stock, at a ratio between one-for-two (1:2) and one-for-one hundred (1:100). Immediately after the special meeting, our Board approved the 2023 Reverse Stock Split. On July 26, 2023, we filed an amendment to our Certificate of Incorporation with the Secretary of State of the State of Delaware to effect the 2023 Reverse Stock Split, which became effective on July 27, 2023.

On August 14, 2023, we received a letter from the Nasdaq Office of General Counsel confirming the decision of the Panel that we demonstrated compliance with the requirements for continued listing on the Nasdaq Capital Market.

On March 4, 2024, we received a deficiency letter from the Staff of Nasdaq (the “March 2024 Deficiency Letter”) notifying us that, for the last 30 consecutive business days, ending on March 1, 2024, the bid price for our common stock had closed below the minimum $1.00 per share requirement for continued inclusion on the Nasdaq Capital Market pursuant to the Bid Price Rule. The March 2024 Deficiency Letter stated that, in accordance with Nasdaq rules, we were provided an initial period of 180 calendar days, or until September 3, 2024 (the “Compliance Date”), to regain compliance with the Bid Price Rule. Compliance is generally achieved if, at any time before the Compliance Date, the bid price for the Company’s common stock closes at $1.00 or more for a minimum of 10 consecutive business days. However, the Staff may, in its discretion, require a company to satisfy the applicable bid price requirement for a period in excess of 10 consecutive business days, but generally no more than 20 consecutive business days, before determining that it has demonstrated an ability to maintain long-term compliance. The March 2024 Deficiency Letter also stated that if we did not regain compliance with the Bid Price Rule by the Compliance Date, we may be eligible for an additional 180 calendar day compliance period. To qualify, we would need to provide written notice of our intention to cure the deficiency during the additional compliance period, by effecting a reverse stock split, if necessary, provided that we meet the continued listing requirement for the market value of publicly held shares and all other initial listing standards, with the exception of the bid price requirement.

On April 15, 2024, we received a letter from the Staff of the Nasdaq (the “April 2024 Determination Letter”) notifying us that such April 2024 Determination Letter superseded the March 2024 Deficiency Letter. The March 2024 Deficiency Letter was issued by the Staff in error.

The April 2024 Determination Letter reiterated that we failed to meet the $1.00 minimum closing bid price requirement for 30 consecutive business days from January 19 through March 1, 2024, as required by Listing Rule 5550(a)(2), and that we are not eligible for an automatic compliance period because the Panel decision relating to us, dated August 14, 2023, subjected us to a Mandatory Panel Monitor for a period of one year pursuant to Listing Rule 5815(d)(4)(B).

Based on the foregoing, we timely requested a hearing before the Panel and were granted a hearing date in June 2024. The hearing request automatically stayed any suspension or delisting action pending the hearing and the expiration of any additional extension period granted by the Panel following the hearing. The April 2024 Determination Letter stated that we would be asked to provide a plan to the Panel to regain compliance. Accordingly, we are currently preparing to present a plan to the Panel that includes a discussion of the events that we believe will enable us to regain compliance in the allotted time frame, which would include a commitment to effect a reverse stock split, if necessary. Pursuant to the Listing Rules, the Panel has the authority to grant us a further extension not to exceed October 14, 2024. The April 2024 Determination Letter further stated that pursuant to Listing Rule 5810(c)(3)(A)(iv) no further automatic compliance period would be provided to us because over the prior two-year period we had effected reverse stock splits with a cumulative ratio of 250 shares or more to one.

In addition, on November 14, 2023, we received a deficiency letter from the Staff notifying us that, based on our stockholders’ equity of $332,000 as of September 30, 2023, as reported in the our Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2023, we were no longer in compliance with the minimum stockholders’ equity requirement for continued listing on the Nasdaq Capital Market under Nasdaq Listing Rule 5550(b)(1), which requires listed companies to maintain stockholders’ equity of at least $2.5 million. We were provided until December 29, 2023 to provide Nasdaq with a specific plan to achieve and sustain compliance with the foregoing listing requirement, which plan was provided to Nasdaq on December 22, 2023. Nasdaq subsequently requested that we submit a plan with greater detail, which we submitted to Nasdaq on January 22, 2024. On February 13, 2024, the Staff provided notice

to us that it had granted us an extension to regain compliance with Nasdaq Listing Rule 5550(b)(1), conditioned upon us undertaking and closing no later than March 31, 2024 for the February 2024 Offering, which we subsequently consummated on February 15, 2024, and publicly disclose evidence of compliance with the minimum stockholders’ equity requirement. In the event we fail to evidence compliance with the stockholders’ equity rule upon the filing of our Form 10-Q for the period ending March 31, 2024 with the SEC and Nasdaq, we may be subject to delisting. We filed our Quarterly Report on Form 10-Q for the quarter ended March 31, 2024 with the SEC on May 13, 2024, which did not evidence compliance with the Nasdaq Listing Rule 5550(b)(1).

As a result, on May 14, 2024, we received an additional staff determination letter from the Staff notifying us that because our Quarterly Report on Form 10-Q for the quarter ended March 31, 2024 that was filed with the SEC on May 13, 2024 reported stockholders’ equity of ($1,934,000) as of March 31, 2024, we did not comply with the minimum $2,500,000 stockholders’ equity requirement for continued listing set forth in Nasdaq Listing Rule 5550(b). Accordingly, this matter serves as an additional basis for delisting of our common stock from The Nasdaq Stock Market and will be considered by the Panel in rendering a determination regarding our continued listing on The Nasdaq Capital Market. We requested a hearing before the Panel and was granted a hearing date in June 2024.

We intend to attempt to take actions to restore our compliance with Nasdaq’s listing requirements and intend to present a plan for compliance at the Panel hearing that is scheduled for June 2024; however, we can provide no assurance that we will be to achieve compliance or that Nasdaq will grant us any additional time to restore compliance especially in light of the fact that we were under review of a Mandatory Panel Monitor and have several current and prior noncompliance issues. Any perception that we may not regain compliance or a delisting of our common stock by Nasdaq could adversely affect our ability to attract new investors, decrease the liquidity of the outstanding shares of our common stock, reduce the price at which such shares trade and increase the transaction costs inherent in trading such shares with overall negative effects for our stockholder. In addition, delisting of our common stock from Nasdaq could deter broker-dealers from making a market in or otherwise seeking or generating interest in our common stock, and might deter certain institutions and persons from investing in our common stock.

USE OF PROCEEDS

We estimate that our net proceeds from the sale of all Units offered in this offering will be approximately $[•] million, after deducting placement agent fees and estimated offering expenses payable by us, based on an assumed offering price of $[•] per Unit, which represents the closing price of our common stock on Nasdaq on [•], 2024, assuming no issuance of Pre-Funded Units in connection with this offering. We estimate that our net proceeds from the sale of 50% of the Units offered in this offering will be approximately $[•] million, after deducting placement agent fees and estimated offering expenses payable by us, based on an assumed offering price of $[•] per Unit, which represents the closing price of our common stock on Nasdaq on [•], 2024, assuming no issuance of Pre-Funded Units in connection with this offering. These estimates exclude the proceeds, if any, from the exercise of the Warrants issued in connection with this offering. If all of the Class C Warrants offered in this offering were sold and exercised for cash, assuming an exercise price of $[•] per share ([•]% of the assumed offering price per Unit in this offering), we would receive additional proceeds of approximately $[•] million. If all of the Class D Warrants offered in this offering were sold and exercised for cash, assuming an exercise price of $[•] per share ([•]% of the assumed offering price per Unit in this offering), we would receive additional proceeds of approximately $[•] million. If 50% of the Class C Warrants offered in this offering were sold and exercised for cash, assuming an exercise price of $[•] per share ([•]% of the assumed offering price per Unit in this offering), we would receive additional net proceeds of approximately $[•] million. If 50% of the Class D Warrants offered in this offering were sold and exercised for cash, assuming an exercise price of $[•] per share ([•]% of the assumed offering price per Unit in this offering), we would receive additional net proceeds of approximately $[•] million. We cannot predict when or if any of these Warrants will be exercised. It is possible that these Warrants may expire and may never be exercised. In addition, if the Class D Warrants are exercised by way of an alternative cashless exercise, assuming receipt of Warrant Stockholder Approval, such exercising holder will receive three shares of our common stock for each Class D Warrant they exercise, without any cash payment to us.

Each $0.05 increase (decrease) in the assumed public offering price of $[•] per Unit, which represents the closing price of our common stock on Nasdaq on [•], 2024, would increase (decrease) the net proceeds to us from this offering by approximately $[•] million, assuming the number of securities offered, as set forth on the cover page of this prospectus, remains the same, and after deducting placement agent fees and estimated offering expenses payable by us and assuming no exercise of Warrants and no issuance of Pre-Funded Units in connection with this offering. Each 500,000 Unit increase (decrease) in the number of Units offered by us in this offering would increase (decrease) the net proceeds to us from this offering by approximately $[•], assuming that the price per Unit for the offering remains at the assumed price of $[•], which represents the closing price of our common stock on Nasdaq on [•], 2024, and after deducting the placement agent fees and estimated offering expenses payable by us and assuming no exercise of the Warrants and no issuance of Pre-Funded Units in connection with this offering.

Because this is a best efforts offering and there is no minimum offering amount required as a condition to the closing of this offering, the actual offering amount, the placement agent fees and net proceeds to us are not presently determinable and may be substantially less than the maximum amounts set forth on the cover page of this prospectus.

We intend to use the proceeds of this offering for working capital and for general corporate purposes. We may temporarily invest the net proceeds in short-term, interest-bearing instruments or other investment-grade securities.

The precise amount and timing of the application of such net proceeds will depend upon our funding requirements and the availability and cost of other funds. Our Board and management will have considerable discretion in the application of the net proceeds from this offering, and it is possible that we may allocate the proceeds differently than investors in the offering may desire or that we may fail to maximize the return on these proceeds. You will be relying on the judgment of our management with regard to the use of proceeds from this offering, and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used appropriately.

DILUTION

If you purchase securities in the offering, you will experience immediate dilution to the extent of the difference between the public offering price per share included as part of the Units or that may be issued upon the exercise of any Pre-Funded Warrants included as part of the Pre-Funded Units and our net tangible book value per share immediately after the offering. Net tangible book value per share is equal to the amount of our total tangible assets, less total liabilities, divided by the number of outstanding shares of our common stock. As of March 31, 2024, our historical net tangible book value was approximately $(2.7 million), or approximately $(0.08) per share.

After giving effect to the assumed sale of [•] Units in this offering at an assumed public offering price of $[•] per Unit, which represents the closing price of our common stock on Nasdaq on [•], 2024 and after deducting the placement agent fees and estimated offering expenses payable by us, but assuming that no Pre-Funded Units are sold in the offering and no exercise of any of the Warrants issued in connection with this offering, our as adjusted net tangible book value as of March 31, 2024 would have been approximately $[•] million, or approximately $[•] per share. This represents an immediate increase in net tangible book value of $[•] per share to existing stockholders and immediate dilution in net tangible book value of $[•] per share to new investors purchasing Units in this offering.

The following table illustrates this dilution on a per-share basis (unaudited):

A $0.10 increase or decrease in the assumed public offering price of $[•] per Unit, based on the last reported sale price for our common stock as reported on the Nasdaq Capital Market on [•], 2024, would decrease the number of shares of common stock offered in this offering by approximately [•] million shares or increase the number of shares of our common stock offered in this offering by approximately [•] million shares, respectively.

We may also increase or decrease the number of Units we are offering. An increase of 100,000 in the number of Units offered by us would increase our as adjusted net tangible book value by approximately $[•] million, or $[•] per share, and decrease the dilution per share to investors participating in this offering by $[•] per share, assuming the assumed offering price per Unit remains the same, no issuance of Pre-Funded Units in this offering and after deducting the estimated placement agent commissions and estimated offering expenses payable by us. Similarly, a decrease of 100,000 in the number of Units offered by us would decrease our as adjusted net tangible book value by approximately $[•] million or $[•] per Units, and increase the dilution per share to investors participating in this offering by $[•] per share, assuming the assumed offering price per Units remains the same, no issuance of Pre-Funded Units in this offering and after deducting the estimated placement agent commissions and estimated offering expenses payable by us. The information discussed above is illustrative only and will adjust based on the actual offering price, the actual number of Units we offer in this offering, and other terms of this offering determined at pricing.

The number of shares of common stock that will be outstanding immediately after this offering as shown above is based on 33,256,943 shares of common stock outstanding as of March 31, 2024. This amount excludes, as of March 31, 2024:

•        464 shares of our common stock issuable upon the exercise of stock options, with a weighted-average exercise price of $6,302.13 per share;

•        46,710 shares of our common stock issuable upon the settlement of outstanding restricted stock units;

•        24,104,005 shares of our common stock issuable upon the exercise of outstanding warrants, with a weighted-average exercise price of $2.68 per share;

•        291 shares of our common stock that may be issued, at the sole discretion of our board of directors, upon the settlement of outstanding phantom restricted stock units, which may also be settled, at the sole discretion of our board of directors, in cash;

•        236 shares of our common stock that may be issued, at the sole discretion of our board of directors, upon the settlement of outstanding stock appreciation rights, which may also be settled, at the sole discretion of our board of directors, in cash;

•        53,677 additional shares of our common stock reserved for future issuance under our 2018 Long-Term Incentive Plan;

•        17,883 shares of our common stock issuable upon the conversion of outstanding shares of Series H Convertible Preferred Stock;

•        485,307 shares of our common stock issuable upon the conversion of outstanding shares of Series J Convertible Preferred Stock; and

•        91,132 shares of our common stock issuable upon paid in-kind dividends on our outstanding shares of Series J Convertible Preferred Stock and Series H Convertible Preferred Stock, assuming all shares of Series J Convertible Preferred Stock and Series H Convertible Preferred Stock remain outstanding as of the dividend dates.

The foregoing discussion and table do not take into account further dilution to new investors that could occur upon the exercise, settlement or conversion of outstanding options, restricted stock units, warrants, phantom restricted stock units, Series H Convertible Preferred Stock, Series H Warrants, Series J Convertible Preferred Stock and Series J Warrants. In addition, we may choose to raise additional capital due to market conditions or strategic considerations. To the extent that additional capital is raised through the sale of equity or convertible debt securities, the issuance of these securities could result in further dilution to our stockholders.

DIVIDEND POLICY

We have not declared or paid dividends to common stockholders since inception and do not plan to pay cash dividends in the foreseeable future to common stockholders. We currently intend to retain earnings, if any, to finance our growth.

Dividends on the Series H Convertible Preferred Stock are paid in-kind (“Series H PIK dividends”) in additional shares of Series H Convertible Preferred Stock based on the stated value of $50.00 per share at the dividend rate of 20.0%. The PIK dividends will be a one-time payment payable to holders of the Series H Convertible Preferred Stock of record at the close of business on the one-year anniversary of the original issue date. On or about May 31, 2024, we issued an aggregate of 1,923 additional shares of Series H Convertible Preferred Stock as Series H PIK dividends.

Dividends on the Series J Convertible Preferred Stock are paid in-kind (“Series J PIK dividends”) in additional shares of Series J Convertible Preferred Stock based on the stated value of $100.00 per share at the dividend rate of 5.0% per quarter. The PIK dividends are paid quarterly payable to holders of the Series J Convertible Preferred Stock of record at the close of business on record at the close of business on October 31, 2023, January 31, 2024, April 30, 2024 and July 31, 2024. We paid a total of: (i) 3,094 shares of Series J PIK dividends to holders of record on October 31, 2023, (ii) 1,217 shares of Series J PIK dividends to holders of record on January 31, 2024, and (iii) 1,318 shares of Series J PIK dividends to holders of record on April 30, 2024.

CAPITALIZATION

The following table sets forth our consolidated cash and cash equivalents and capitalization as of March 31, 2024:

•        on an actual basis; and

•        on an as adjusted basis to give effect to the sale by us of [•] Units in this offering at an assumed public offering price of $[•] per Unit, which represents the closing price of our common stock on Nasdaq on [•], 2024, after deducting the estimated placement agent fees and estimated offering expenses, and assuming no sale of any Pre-Funded Units in this offering and no exercise of the Warrants issued in connection with this offering.

You should read the following table in conjunction with the “Use of Proceeds” section included elsewhere in this prospectus and the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our consolidated financial statements and related notes and the other financial and statistical information included in our Form 10-K and Form 10-Q, which are incorporated by reference in this prospectus. See the section in this prospectus entitled “Incorporation of Certain Information by Reference” for more information regarding documents incorporated by reference herein.

A $0.10 increase (decrease) in the assumed public offering price of $[•] per Unit would increase (decrease) the cash and cash equivalents, additional paid-in capital, total stockholders’ equity (deficit) and total capitalization by approximately $[•] million, assuming that the number of Units offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting the estimated placement agent fees and estimated offering expenses payable by us and assuming no exercise of Warrants and no issuance of Pre-Funded Units in this offering.

DESCRIPTION OF OUR CAPITAL STOCK

The following summary description sets forth some of the general terms and provisions of our capital stock.

For a more detailed description of our capital stock, you should refer to the applicable provisions of the General Corporation Law of the State of Delaware (the “DGCL”) and our Restated Certificate of Incorporation, as amended (the “Charter”), and our Eighth Amended and Restated Bylaws (“Bylaws”). Copies of our Charter and Bylaws are included as exhibits to the registration statement of which this prospectus forms a part.

Common Stock

Voting Rights.    Holders of our common stock are entitled to one vote per share. Except as required by the DGCL, our Charter or our Bylaws, matters will generally be decided by the affirmative vote of the holders of a majority in voting power of the shares of capital stock present in person or represented by proxy at a meeting and entitled to vote on the subject matter. Our Bylaws provide that each of our directors is elected by the affirmative vote of a majority of the votes cast with respect to such director in uncontested elections. In a contested election, each of our directors is elected by an affirmative vote of a plurality of the votes cast by the shares represented and entitled to vote with respect to the election of such director. A “contested election” is defined in our Bylaws as an election with respect to which, as of the record date for the meeting at which directors are to be elected, the number of nominees exceeds the number of directors to be elected at such meeting. Vacancies on our Board may be filled by an affirmative vote of two-thirds of the remaining members of our Board or at a meeting of the stockholders in the manner set forth above.

Dividend Rights.    Subject to any preferential rights of any outstanding shares of our preferred stock to receive dividends before any dividends may be paid on our common stock, the holders of our common stock will be entitled to share ratably in any dividends that may be declared by our Board out of funds legally available for the payment of dividends. Our ability to pay dividends on our common stock will be limited by restrictions on our ability to pay dividends or make distributions to our stockholders and on the ability of our subsidiaries to pay dividends or make distributions to us, in each case, under the terms of our current, and any future, agreements governing our indebtedness.

Other Rights.    Each holder of our common stock is subject to, and may be adversely affected by, the rights of the holders of any series of preferred stock that our Board may designate and we may issue in the future. Holders of our common stock have no preemptive, conversion or other rights to subscribe for additional shares. Our common stock does not carry any redemption rights or any preemptive rights enabling a holder to subscribe for, or receive shares of, any class of our common stock or any other securities convertible into shares of any class of our common stock.

Liquidation Rights.    Subject to any preferential rights of any outstanding shares of our preferred stock, in the event of our liquidation, dissolution or winding up, holders of our common stock are entitled to share ratably in the assets remaining after payment of liabilities and the liquidation preferences of any outstanding preferred stock.

Standstill Agreements.    Pursuant to (1) a standstill agreement with Jack W. Schuler, Renate Schuler and the Schuler Family Foundation (collectively, the “Schuler Parties”), dated November 10, 2015 (as amended on August 1, 2016 and November 9, 2017, the “Schuler Standstill Agreement”), and (2) a standstill agreement with Larry N. Feinberg, Oracle Partners, L.P., Oracle Institutional Partners, L.P., Oracle Ten Fund Master, L.P., Oracle Associates, LLC and Oracle Investment Management, Inc. (collectively, the “Oracle Parties”) dated November 10, 2015 (as amended on August 1, 2016 and November 9, 2017, the “Oracle Standstill Agreement” and, together with the Schuler Standstill Agreement, the “Standstill Agreements”), each of the Schuler Parties and the Oracle Parties agreed with respect to itself and its associates and affiliates (i) not to purchase or acquire any shares of our common stock if such a purchase would result in aggregate beneficial ownership by it and its affiliates and associates in excess of 41% of the issued and outstanding shares of our common stock and (ii) not to sell, transfer or otherwise convey shares of our common stock (or warrants or other rights to acquire shares of our common stock) to anyone who will immediately thereafter beneficially own shares in excess of 20% of the issued and outstanding shares of our common stock, as a result of such transfer and other transfers from third parties.

Preferred Stock

Our Charter authorizes our Board to provide for the issuance of shares of up to 1,000,000 shares of preferred stock in one or more series without further authorization from stockholders. Prior to issuance of shares of each series, our Board is required by the DGCL and our Charter to fix the designation, powers, preferences and rights of the shares of such series and the qualifications, limitations or restrictions thereof. As of May 15, 2024, we had: (i) 5,000 shares of Series H Convertible Preferred Stock outstanding (equal to 17,883 shares of our common stock issuable upon the conversion of these outstanding shares of Series H Convertible Preferred Stock), and (ii) 14,606 shares of Series J convertible Preferred Stock outstanding (equal to 448,037 shares of our common stock issuable upon the conversion of these outstanding shares of Series J Convertible Preferred Stock). No other shares of preferred stock were outstanding as of the date of this prospectus.

Series H Convertible Preferred Stock

Maturity.    The Series H Convertible Preferred Stock matures two (2) years from the original issue date.

Ranking and Liquidation Preference.    Upon any liquidation, dissolution or winding-up of the Company, whether voluntary or involuntary, prior and in preference to the common stock, holders of the Series H Convertible Preferred Stock shall be entitled to receive out of the assets available for distribution to stockholders an amount equal in cash to 100% of the aggregate stated value of $50.00 per share (the “Series H Stated Value”) of all shares of Series H Convertible Preferred Stock held by such holder, and any other fees then due and owing thereon under the certificate of designation establishing the Series H Convertible Preferred Stock (the “Series H Certificate of Designation”), and no more, and if the assets of the Company shall be insufficient to pay in full such amounts, then the entire assets to be distributed to the holders shall be ratably distributed among the holders in accordance with the respective amounts that would be payable on such shares if all amounts payable thereon were paid in full.

Dividends.    The Series H Certificate of Designation provides that dividends on the Series H Convertible Preferred Stock shall be paid in-kind (“Series H PIK dividends”) in additional shares of Series H Convertible Preferred Stock based on the Series H Stated Value of $50.00 per share at the dividend rate of 20.0% (the “Series H Dividend Rate”). The Series H PIK dividends will be a one-time payment payable to holders of the Series H Convertible Preferred of record at the close of business on the one-year anniversary of the original issuance date (the “Series H Dividend Record Date”). Series H PIK dividends on each share of Series H Convertible Preferred Stock shall be paid three business days after the Series H Dividend Record Date in additional fully paid and nonassessable, registered shares of Series H Convertible Preferred Stock in a number equal to the quotient obtained by dividing (A) the product obtained by multiplying (i) the Series H Dividend Rate and (ii) the Series H Stated Value of $50.00 per share, by (B) $26.00.

Conversion.    The Series H Convertible Preferred Stock is convertible at any time at the option of the holder. Except as provided below, the Series H Convertible Preferred Stock is not convertible into or exchangeable for any other securities or property.

Conversion at Option of Holder.    Each share of Series H Convertible Preferred Stock is convertible into shares of our common stock at the conversion price of $13.98 per share of our common stock (the “Series H Conversion Price”), which Series H Conversion Price is subject to adjustment and is based on the closing price of our common stock on May 23, 2023.

Holders shall effect conversions of the Series H Convertible Preferred Stock by providing us a conversion notice (a “Series H Notice of Conversion”), duly completed and executed. The Series H Notice of Conversion must specify the number of shares of Series H Convertible Preferred Stock then held by the holder and the number of such shares which the holder is converting. To effect conversions of shares of Series H Convertible Preferred Stock, a holder shall not be required to surrender the certificate(s), if any, representing the shares of Series H Convertible Preferred Stock to us unless all of the shares of Series H Convertible Preferred Stock represented thereby are so converted, in which case such holder shall deliver the certificate representing such shares of Series H Convertible Preferred Stock promptly following the conversion date at issue. Shares of Series H Convertible Preferred Stock converted into our shares of Common Stock shall be canceled and shall not be reissued.

If, at any time while the Series H Convertible Preferred Stock is outstanding: we (A) pay a stock dividend or otherwise make a distribution or distributions payable in shares of our common stock or any other Common Stock Equivalents (as defined in the Series H Certificate of Designation) (which, for avoidance of doubt, shall not include any shares of Common Stock issued by us upon conversion of the Series H Convertible Preferred Stock, or payment of a dividend on the Series H Convertible Preferred Stock) with respect to the then outstanding shares of Common Stock; (B) subdivide outstanding shares of Common Stock into a larger number of shares; (C) combine (including by way of a reverse stock split) outstanding shares of Common Stock into a smaller number of shares or (D) issue, in the event of a reclassification of shares of the Common Stock, any shares of our capital stock, which we refer to collectively as the “Anti-Dilution Provisions”, then the Series H Conversion Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock (excluding any treasury shares) outstanding immediately before such event and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event (excluding any treasury shares). Any adjustment made as a result of the Anti-Dilution Provisions shall become effective immediately after the record date for the determination of shareholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision or combination. All calculations will be made to the nearest cent or the nearest 1/100th of a share, as the case may be. For purposes of the Anti-Dilution Provisions, the number of shares of Common Stock deemed to be issued and outstanding as of a given date shall be the sum of the number of shares of Common Stock (excluding any treasury shares) issued and outstanding. Whenever the Series H Conversion Price is adjusted pursuant to any Anti-Dilution Provision, we will promptly deliver to each holder of Series H Convertible Preferred Stock a notice setting forth the Series H Conversion Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Notwithstanding the foregoing in no event may the Series H Conversion Price be less than the par value per share of Series H Convertible Preferred Stock.

Obligations Absolute.    Subject to holder’s right to rescind a notice of conversion, our obligation to issue and deliver the shares of Common Stock upon conversion of Series H Convertible Preferred Stock in accordance with its terms are absolute and unconditional, irrespective of any action or inaction by a holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against any Person or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by such holder or any other Person of any obligation to us or any violation or alleged violation of law by such holder or any other Person, and irrespective of any other circumstance which might otherwise limit our obligation to such holder in connection with the issuance of such shares of Common Stock. If we fail to deliver to a holder shares of Common Stock upon conversion by the Share Delivery Date (as defined in the Series H Certificate of Designation) applicable to such conversion, we shall pay to such holder, in cash, as liquidated damages and not as a penalty, for each $250 of Series H Stated Value of Series H Convertible Preferred Stock being converted, $2.50 per Trading Day (as defined in the Series H Certificate of Designation) (increasing to $5 per Trading Day on the third Trading Day after the Share Delivery Date and increasing to $10 per Trading Day on the sixth Trading Day after the Share Delivery Date) for each Trading Day after the Share Delivery Date until such Conversion Shares (as defined in the Series H Certificate of Designation) are delivered or holder rescinds such conversion.

Buy-In on Failure to Timely Deliver Certificates Upon Conversion.    If we fail to deliver to a holder the applicable certificate or certificates or to effect a delivery via DWAC, as applicable, by the Share Delivery Date (other than a failure caused by incorrect or incomplete information provided by the holder to us), and if after such Share Delivery Date the holder is required by its brokerage firm to purchase (in an open market transaction or otherwise), or the holder’s brokerage firm otherwise purchases, shares of Common Stock to deliver in satisfaction of a sale by such holder of the Conversion Shares which the holder was entitled to receive upon the conversion relating to such Share Delivery Date (a “Buy-In”), then we are obligated to (A) pay in cash to the holder (in addition to any other remedies available to or elected by the holder) the amount by which (x) the holder’s total purchase price (including any brokerage

commissions) for the shares of Common Stock so purchased exceeds (y) the product of (1) the aggregate number of shares of Common Stock that such holder was entitled to receive from the conversion at issue multiplied by (2) the actual sale price at which the sell order giving rise to such purchase obligation was executed (including any brokerage commissions) and (B) at the option of the holder, either reissue (if surrendered) the shares of Series H Convertible Preferred Stock equal to the number of shares of Series H Convertible Preferred Stock submitted for conversion or deliver to the holder the number of shares of Common Stock that would have been issued if we had timely complied with our delivery requirements. For example, if a holder purchases shares of Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted conversion of shares of Series H Convertible Preferred Stock with respect to which the actual sale price (including any brokerage commissions) giving rise to such purchase obligation was a total of $10,000 under clause (A) of the immediately preceding sentence, we would be required to pay such holder $1,000. The holder shall provide us written notice, within three Trading Days after the occurrence of a Buy-In, indicating the amounts payable to such holder in respect of such Buy-In together with applicable confirmations and other evidence reasonably requested by us. Nothing herein shall limit a holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect our failure to timely deliver certificates representing shares of Common Stock upon conversion of the shares of Series H Convertible Preferred Stock as required pursuant to the terms hereof; provided, however, that the holder shall not be entitled to both (i) require the reissuance of the shares of Series H Convertible Preferred Stock submitted for conversion for which such conversion was not timely honored and (ii) receive the number of shares of Common Stock that would have been issued if we had timely complied with applicable delivery requirements.

Reservation of Shares Issuable Upon Conversion.    We have agreed that we will at all times reserve and keep available out of our authorized and unissued shares of Common Stock for the sole purpose of issuance upon conversion of the Series H Convertible Preferred Stock, free from preemptive rights or any other actual contingent purchase rights of Persons other than the holders of the Series H Convertible Preferred Stock, not less than such aggregate number of shares of the Common Stock as shall be issuable upon the conversion of all outstanding shares of Series H Convertible Preferred Stock. We have further agreed that all shares of Common Stock that shall be so issuable shall, upon issue, be duly authorized, validly issued, fully paid, nonassessable and free and clear of all liens and other encumbrances.

Beneficial Ownership Limitation.    Notwithstanding anything herein to the contrary, we shall not effect any conversion of the Series H Convertible Preferred Stock, and a Holder shall not have the right to convert any portion of the Series H Convertible Preferred Stock, to the extent that, after giving effect to the conversion set forth on the applicable Series H Notice of Conversion, such Holder (together with such Holder’s Affiliates, and any Persons acting as a group together with such Holder or any of such Holder’s Affiliates (such Persons, “Series H Attribution Parties”)) would beneficially own in excess of the Beneficial Ownership Limitation (as defined below). For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by such Holder and its Affiliates and Series H Attribution Parties shall include the number of shares of Common Stock issuable upon conversion of the Series H Convertible Preferred Stock with respect to which such determination is being made, but shall exclude the number of shares of Common Stock which are issuable upon (i) conversion of the remaining, unconverted Series H Convertible Preferred Stock beneficially owned by such Holder or any of its Affiliates or Series H Attribution Parties and (ii) exercise or conversion of the unexercised or unconverted portion of any other of our securities subject to a limitation on conversion or exercise analogous to the limitation contained herein (including, without limitation, the Series H Convertible Preferred Stock) beneficially owned by such Holder or any of its Affiliates or Series H Attribution Parties. Except as set forth in the preceding sentence, for purposes of this section, beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. To the extent that the limitation contained in this section applies, the determination of whether the Series H Convertible Preferred Stock is convertible (in relation to other securities owned by such Holder together with any Affiliates and Series H Attribution Parties) and of how many shares of Series H Convertible Preferred Stock are convertible shall be in the sole discretion of such Holder, and the submission of a Series H Notice of Conversion shall be deemed to be such Holder’s determination of whether the shares of Series H Convertible Preferred Stock may be converted (in relation to other securities owned by such Holder together with any Affiliates and Series H Attribution Parties) and how many shares of the Series H Convertible Preferred Stock are convertible, in each case subject to the Beneficial Ownership Limitation. To ensure compliance with this restriction, each Holder will be deemed to represent to us each time it delivers a Series H Notice of Conversion that such Series H Notice of Conversion has not violated the restrictions set forth in this section and we shall have no obligation to verify or confirm the accuracy of such determination. In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the

rules and regulations promulgated thereunder. For purposes of this section, in determining the number of outstanding shares of Common Stock, a Holder may rely on the number of outstanding shares of Common Stock as stated in the most recent of the following: (i) our most recent periodic or annual report filed with the Commission, as the case may be, (ii) a more recent public announcement by us or (iii) a more recent written notice by us or the Transfer Agent setting forth the number of shares of Common Stock outstanding. Upon the written or oral request (which may be via email) of a Holder, we within one (1) Trading Day confirm orally and in writing to such Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of our securities, including the Series H Convertible Preferred Stock, by such Holder or its Affiliates or Series H Attribution Parties since the date as of which such number of outstanding shares of Common Stock was reported. The “Beneficial Ownership Limitation” shall be 4.99% (or, upon election by a Holder prior to the issuance of any shares of Series H Convertible Preferred Stock, 9.99%) of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock issuable upon conversion of Series H Convertible Preferred Stock held by the applicable Holder. A Holder, upon notice to us, may increase or decrease the Beneficial Ownership Limitation provisions of this section applicable to its Series H Convertible Preferred Stock; provided, that the Beneficial Ownership Limitation shall not in any event exceed 9.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock upon conversion of this Series H Convertible Preferred Stock held by the Holder and the provisions of this section shall continue to apply. Any such increase will not be effective until the 61st day after such notice is delivered to us and shall only apply to such Holder and no other Holder. The Beneficial Ownership Limitation shall not be waived by us or the Holder and upon issuance of the Series H Convertible Preferred Stock by us, and the purchase thereof by the Holder, each of us and the Holder shall be deemed to acknowledge such limitation and to agree not to waive it. The provisions of this section shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this section to correct this section (or any portion hereof) which may be defective or inconsistent with the intended Beneficial Ownership Limitation contained herein or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations contained in this Section shall apply to a successor holder of Series H Convertible Preferred Stock.

Subsequent Rights Offerings.    In addition to any Anti-Dilution Adjustments described above, if at any time we grant, issue or sell any Common Stock Equivalents or rights to purchase stock, warrants, securities or other property pro rata to the record holders of Common Stock or any class thereof (the “Series H Purchase Rights”), then the Holder will be entitled to acquire, upon the terms applicable to such Series H Purchase Rights, the aggregate Series H Purchase Rights which the Holder could have acquired if the Holder had held the number of shares of Common Stock acquirable upon complete conversion of such Holder’s Series H Convertible Preferred Stock (without regard to any limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the date on which a record is taken for the grant, issuance or sale of such Series H Purchase Rights, or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the grant, issue or sale of such Series H Purchase Rights (provided, however, that, to the extent that the Holder’s right to participate in any such Purchase Right would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such Purchase Right to such extent (or beneficial ownership of such shares of Common Stock as a result of such Purchase Right to such extent) and such Purchase Right to such extent shall be held in abeyance for the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation).

Pro Rata Distributions.    During such time as the Series H Convertible Preferred Stock is outstanding, if we declare or make any dividend or other distribution of our assets (or rights to acquire its assets) to holders of Common Stock, by way of return of capital or otherwise (including, without limitation, any distribution of cash, stock or other securities, property or options by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction) ( a “Series H Distribution”), then, in each such case, the Holder shall be entitled to participate in such Series H Distribution to the same extent that the Holder would have participated therein if the Holder had held the number of shares of Common Stock acquirable upon complete conversion of the Series H Convertible Preferred Stock (without regard to any limitations on conversion hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the date of which a record is taken for such Series H Distribution, or, if no such record is taken, the date as of which the record holders of shares of our common stock are to be determined for the participation in such Series H Distribution (provided, however, that, to the extent that the Holder’s right to participate in any such Series H Distribution would result in the Holder exceeding the Beneficial Ownership Limitation, then the

Holder shall not be entitled to participate in such Series H Distribution to such extent (or in the beneficial ownership of any shares of Common Stock as a result of such Series H Distribution to such extent) and the portion of such Series H Distribution shall be held in abeyance for the benefit of the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation).

Fundamental Transactions.    In the event of a Fundamental Transaction (as defined in the Series H Certificate of Designation) and generally including any reorganization, recapitalization or reclassification of our common stock, the sale, transfer or other disposition of all or substantially all of our properties or assets, our consolidation or merger with or into another person, or the acquisition of more than 50% of our outstanding Common Stock, the holders of the Series H Convertible Preferred Stock will be entitled to receive upon conversion of the Series H Convertible Preferred Stock the kind and amount of securities, cash or other property that the holders would have received had they converted the Series H Convertible Preferred Stock immediately prior to such Fundamental Transaction (without regard to the Beneficial Ownership Limitation).

Mandatory Redemption.    If any shares of Series H Convertible Preferred Stock are outstanding at the end of the two (2) year term, then we shall promptly redeem all of such outstanding shares of Series H Convertible Preferred Stock on a pro rata basis among all of the Holders of Series H Convertible Preferred Stock commencing on the two-year anniversary of the original issue date in cash at a price per Series H Convertible Preferred Share equal to the sum of (x) 100% of the Series H Stated Value plus (y) all other amounts due in respect of the Series H Convertible Preferred Stock (if any).

Limited Voting Rights.    Holders of the Series H Convertible Preferred Stock will not have any voting rights, except as described below or as otherwise required by law.

In any matter in which the Series H Convertible Preferred Stock may vote (as expressly provided herein or as may be required by law), each share of Series H Convertible Preferred Stock will be entitled to one vote per share. So long as any shares of Series H Convertible Preferred Stock remain outstanding, we will not, without the consent or the affirmative vote of a majority of the outstanding shares of Series H Convertible Preferred Stock, given in person or by proxy, either in writing without a meeting or by vote at any meeting called for the purpose:

•        alter or change adversely the powers, preferences or rights given to the Series H Convertible Preferred Stock or alter or amend the Series H Certificate of Designation;

•        increase the number of authorized shares of Series H Convertible Preferred Stock; or

•        enter into any agreement with respect to any of the foregoing.

The rules and procedures for calling and conducting any meeting of the holders of the Series H Convertible Preferred Stock (including, without limitation, the fixing of a record date in connection therewith), the solicitation and use of proxies at such a meeting, the obtaining of written consents and any other aspect or matter with regard to such a meeting or such consents shall be governed by any rules the Board (or a duly authorized committee of the Board), in its discretion, may adopt from time to time, which rules and procedures shall conform to the requirements of our Charter, Bylaws, applicable law and any national securities exchange or other trading facility on which the Series H Convertible Preferred Stock may be listed or traded at the time.

Holders of the Series H Convertible Preferred Stock will not have any voting rights with respect to, and the consent of the holders of the Series H Convertible Preferred Stock is not required for, the taking of any corporate action, including any merger or consolidation involving us or a sale of all or substantially all of our assets, regardless of the effect that such merger, consolidation or sale may have upon the powers, preferences, voting power or other rights or privileges of the Series H Convertible Preferred Stock, except as described above.

No Preemptive Rights.    No holders of the Series H Convertible Preferred Stock will, as holders of Series H Convertible Preferred Stock, have any preemptive rights to purchase or subscribe for the Common Stock or any other security.

Exclusion of Other Rights.    The shares of the Series H Convertible Preferred Stock do not have any voting powers, preferences or relative, participating, optional or other special rights, or qualifications, limitations or restrictions thereof, other than as set forth in the Series H Certificate of Designation or in our Charter.

Registration; Transfer.    Pursuant to the terms of the Series H Certificate of Designation, we are obligated to maintain an effective registration statement covering: (a) the issuance of shares of Common Stock issuable upon conversion of the Series H Convertible Preferred Stock and (b) the issuance of additional shares of Series H Convertible Preferred Stock pursuant to our obligation to pay Series H PIK dividends, in each case, until such time as no Series H Convertible Preferred Stock (and no Warrants exercisable for shares of Series H Convertible Preferred Stock) remain outstanding, unless there is available an exemption from, or a transaction not subject to, the registration requirements of the Securities Act that covers the issuance of the Series H Convertible Preferred Stock and the shares of Common Stock issuable upon conversion of such shares of Series H Convertible Preferred Stock.

Series J Convertible Preferred Stock

Maturity.    The Series J Convertible Preferred Stock matures one (1) year from the original issue date.

Ranking and Liquidation Preference.    Upon any liquidation, dissolution or winding-up of the Company, whether voluntary or involuntary, prior and in preference to the Common Stock, holders of the Series J Convertible Preferred Stock shall be entitled to receive out of the assets available for distribution to stockholders an amount equal in cash to 100% of the aggregate Stated Value of $100.00 per share (the “Stated Value”) of all shares of Series J Convertible Preferred Stock held by such holder, and any other fees then due and owing thereon under the certificate of designation establishing the Series J Convertible Preferred Stock (the “Series J Certificate of Designation”), and no more, and if the assets of the Company shall be insufficient to pay in full such amounts, then the entire assets to be distributed to the holders shall be ratably distributed among the holders in accordance with the respective amounts that would be payable on such shares if all amounts payable thereon were paid in full.

Dividends.    The Series J Certificate of Designation shall provide that dividends on the Series J Convertible Preferred Stock shall be paid in-kind (“Series J PIK dividends”) in additional shares of Series J Convertible Preferred Stock based on the stated value of $100.00 per share and the annual dividend rate of 20.0% and a quarterly dividend rate of 5.0% (the “Quarterly Dividend Rate”). The Series J PIK dividends will be paid on a quarterly basis for one year following the issuance of the Series J Convertible Preferred Stock payable to holders of the Series J Convertible Preferred of record at the close of business at the end of October 31, 2023, January 31, 2024, April 30, 2024 and July 31, 2024 (each a “Series J Dividend Record Date”) at the Quarterly Dividend Rate. Series J PIK dividends on each share of Series J Convertible Preferred Stock shall be paid three business days after each Series J Dividend Record Date in additional fully paid and nonassessable, registered shares of Series J Convertible Preferred Stock in a number equal to the quotient obtained by dividing (A) the product obtained by multiplying (i) the Quarterly Dividend Rate and (ii) the stated value of $100.00 per share, by (B) $60.00.

Conversion.    The Series J Convertible Preferred Stock is convertible at any time at the option of the holder. Except as provided below, the Series J Convertible Preferred Stock is not convertible into or exchangeable for any other securities or property.

Conversion at Option of Holder.    Each share of Series J Convertible Preferred Stock is convertible into shares of our common stock the conversion price of $4.37 per share of our common stock (the “Series J Conversion Price”), which Series J Conversion Price is subject to adjustment and is based on the closing price of our common stock on August 31, 2023.

Holders shall effect conversions of the Series J Convertible Preferred Stock by providing us a conversion notice (a “Notice of Conversion”), duly completed and executed. The Notice of Conversion must specify the number of shares of Series J Convertible Preferred Stock then held by the holder and the number of such shares which the holder is converting. To effect conversions of shares of Series J Convertible Preferred Stock, a holder shall not be required to surrender the certificate(s), if any, representing the shares of Series J Convertible Preferred Stock to us unless all of the shares of Series J Convertible Preferred Stock represented thereby are so converted, in which case such holder shall deliver the certificate representing such shares of Series J Convertible Preferred Stock promptly following the conversion date at issue. Shares of Series J Convertible Preferred Stock converted into our shares of Common Stock shall be canceled and shall not be reissued.

If, at any time while the Series J Convertible Preferred Stock is outstanding: we (A) pay a stock dividend or otherwise make a distribution or distributions payable in shares of our common stock or any other Common Stock Equivalents (as defined in the Series J Certificate of Designation) (which, for avoidance of doubt, shall not include any shares of Common Stock issued by us upon conversion of the Series J Convertible Preferred Stock, or payment of a dividend on

the Series J Convertible Preferred Stock) with respect to the then outstanding shares of Common Stock; (B) subdivide outstanding shares of Common Stock into a larger number of shares; (C) combine (including by way of a reverse stock split) outstanding shares of Common Stock into a smaller number of shares or (D) issue, in the event of a reclassification of shares of the Common Stock, any shares of our capital stock, which we refer to collectively as the “Anti-Dilution Provisions”, then the Series J Conversion Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock (excluding any treasury shares) outstanding immediately before such event and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event (excluding any treasury shares). Any adjustment made as a result of the Anti-Dilution Provisions shall become effective immediately after the record date for the determination of shareholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision or combination. All calculations will be made to the nearest cent or the nearest 1/100th of a share, as the case may be. For purposes of the Anti-Dilution Provisions, the number of shares of Common Stock deemed to be issued and outstanding as of a given date shall be the sum of the number of shares of Common Stock (excluding any treasury shares) issued and outstanding.

Whenever the Series J Conversion Price is adjusted pursuant to any Anti-Dilution Provision, we will promptly deliver to each holder of Series J Convertible Preferred Stock a notice setting forth the Series J Conversion Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Notwithstanding the foregoing in no event may the Series J Conversion Price be less than the par value per share of Series J Convertible Preferred Stock.

Obligations Absolute.    Subject to holder’s right to rescind a notice of conversion, our obligation to issue and deliver the shares of Common Stock upon conversion of Series J Convertible Preferred Stock in accordance with its terms are absolute and unconditional, irrespective of any action or inaction by a holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against any Person or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by such holder or any other Person of any obligation to us or any violation or alleged violation of law by such holder or any other Person, and irrespective of any other circumstance which might otherwise limit our obligation to such holder in connection with the issuance of such shares of Common Stock. If we fail to deliver to a holder shares of Common Stock upon conversion by the Share Delivery Date (as defined in the Series J Certificate of Designation) applicable to such conversion, we shall pay to such holder, in cash, as liquidated damages and not as a penalty, for each $250 of Stated Value of Series J Convertible Preferred Stock being converted, $2.50 per Trading Day (increasing to $5 per Trading Day on the third Trading Day after the Share Delivery Date and increasing to $10 per Trading Day on the sixth Trading Day after the Share Delivery Date) for each Trading Day after the Share Delivery Date until such Conversion Shares are delivered or Holder rescinds such conversion.

Buy-In on Failure to Timely Deliver Certificates Upon Conversion.    If we fail to deliver to a holder the applicable certificate or certificates or to effect a delivery via DWAC, as applicable, by the Share Delivery Date (other than a failure caused by incorrect or incomplete information provided by the holder to us), and if after such Share Delivery Date the holder is required by its brokerage firm to purchase (in an open market transaction or otherwise), or the holder’s brokerage firm otherwise purchases, shares of Common Stock to deliver in satisfaction of a sale by such holder of the Conversion Shares which the holder was entitled to receive upon the conversion relating to such Share Delivery Date (a “Buy-In”), then we are obligated to (A) pay in cash to the holder (in addition to any other remedies available to or elected by the holder) the amount by which (x) the holder’s total purchase price (including any brokerage commissions) for the shares of Common Stock so purchased exceeds (y) the product of (1) the aggregate number of shares of Common Stock that such holder was entitled to receive from the conversion at issue multiplied by (2) the actual sale price at which the sell order giving rise to such purchase obligation was executed (including any brokerage commissions) and (B) at the option of the holder, either reissue (if surrendered) the shares of Series J Convertible Preferred Stock equal to the number of shares of Series J Convertible Preferred Stock submitted for conversion or deliver to the holder the number of shares of Common Stock that would have been issued if we had timely complied with our delivery requirements. For example, if a holder purchases shares of Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted conversion of shares of Series J Convertible Preferred Stock with respect to which the actual sale price (including any brokerage commissions) giving rise to such purchase obligation was a total of $10,000 under clause (A) of the immediately preceding sentence, we would be required to pay such holder $1,000. The holder shall provide us written notice, within three Trading Days after the occurrence of a Buy-In, indicating the amounts payable to such holder in respect of such Buy-In together with applicable confirmations and other evidence reasonably requested by us. Nothing herein shall limit a holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or

injunctive relief with respect our failure to timely deliver certificates representing shares of Common Stock upon conversion of the shares of Series J Convertible Preferred Stock as required pursuant to the terms hereof; provided, however, that the holder shall not be entitled to both (i) require the reissuance of the shares of Series J Convertible Preferred Stock submitted for conversion for which such conversion was not timely honored and (ii) receive the number of shares of Common Stock that would have been issued if we had timely complied with applicable delivery requirements.

Reservation of Shares Issuable Upon Conversion.    We have agreed that we will at all times reserve and keep available out of our authorized and unissued shares of Common Stock for the sole purpose of issuance upon conversion of the Series J Convertible Preferred Stock, free from preemptive rights or any other actual contingent purchase rights of Persons other than the holders of the Series J Convertible Preferred Stock, not less than such aggregate number of shares of the Common Stock as shall be issuable upon the conversion of all outstanding shares of Series J Convertible Preferred Stock. We have further agreed that all shares of Common Stock that shall be so issuable shall, upon issue, be duly authorized, validly issued, fully paid, nonassessable and free and clear of all liens and other encumbrances.

Beneficial Ownership Limitation.    Notwithstanding anything herein to the contrary, we shall not effect any conversion of the Series J Convertible Preferred Stock, and a Holder shall not have the right to convert any portion of the Series J Convertible Preferred Stock, to the extent that, after giving effect to the conversion set forth on the applicable Notice of Conversion, such Holder (together with such Holder’s Affiliates, and any Persons acting as a group together with such Holder or any of such Holder’s Affiliates (such Persons, “Attribution Parties”)) would beneficially own in excess of the Beneficial Ownership Limitation (as defined below). For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by such Holder and its Affiliates and Attribution Parties shall include the number of shares of Common Stock issuable upon conversion of the Series J Convertible Preferred Stock with respect to which such determination is being made, but shall exclude the number of shares of Common Stock which are issuable upon (i) conversion of the remaining, unconverted Series J Convertible Preferred Stock beneficially owned by such Holder or any of its Affiliates or Attribution Parties and (ii) exercise or conversion of the unexercised or unconverted portion of any other of our securities subject to a limitation on conversion or exercise analogous to the limitation contained herein (including, without limitation, the Series J Convertible Preferred Stock) beneficially owned by such Holder or any of its Affiliates or Attribution Parties. Except as set forth in the preceding sentence, for purposes of this section, beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. To the extent that the limitation contained in this section applies, the determination of whether the Series J Convertible Preferred Stock is convertible (in relation to other securities owned by such Holder together with any Affiliates and Attribution Parties) and of how many shares of Series J Convertible Preferred Stock are convertible shall be in the sole discretion of such Holder, and the submission of a Notice of Conversion shall be deemed to be such Holder’s determination of whether the shares of Series J Convertible Preferred Stock may be converted (in relation to other securities owned by such Holder together with any Affiliates and Attribution Parties) and how many shares of the Series J Convertible Preferred Stock are convertible, in each case subject to the Beneficial Ownership Limitation. To ensure compliance with this restriction, each Holder will be deemed to represent to us each time it delivers a Notice of Conversion that such Notice of Conversion has not violated the restrictions set forth in this section and we shall have no obligation to verify or confirm the accuracy of such determination. In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. For purposes of this section, in determining the number of outstanding shares of Common Stock, a Holder may rely on the number of outstanding shares of Common Stock as stated in the most recent of the following: (i) our most recent periodic or annual report filed with the Commission, as the case may be, (ii) a more recent public announcement by us or (iii) a more recent written notice by us or the Transfer Agent setting forth the number of shares of Common Stock outstanding. Upon the written or oral request (which may be via email) of a Holder, we within one (1) Trading Day confirm orally and in writing to such Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of our securities, including the Series J Convertible Preferred Stock, by such Holder or its Affiliates or Attribution Parties since the date as of which such number of outstanding shares of Common Stock was reported. The “Beneficial Ownership Limitation” shall be 4.99% (or, upon election by a Holder prior to the issuance of any shares of Series J Convertible Preferred Stock, 9.99%) of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock issuable upon conversion of Series J Convertible Preferred Stock held by the applicable Holder. A Holder, upon notice to us, may increase or decrease the Beneficial Ownership Limitation provisions of this section applicable to its Series J Convertible Preferred Stock; provided, that the Beneficial Ownership Limitation shall

not in any event exceed 9.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock upon conversion of this Series J Convertible Preferred Stock held by the Holder and the provisions of this section shall continue to apply. Any such increase will not be effective until the 61st day after such notice is delivered to us and shall only apply to such Holder and no other Holder. The Beneficial Ownership Limitation shall not be waived by us or the Holder and upon issuance of the Series J Convertible Preferred Stock by us, and the purchase thereof by the Holder, each of us and the Holder shall be deemed to acknowledge such limitation and to agree not to waive it. The provisions of this section shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this section to correct this section (or any portion hereof) which may be defective or inconsistent with the intended Beneficial Ownership Limitation contained herein or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations contained in this Section shall apply to a successor holder of Series J Convertible Preferred Stock.

Subsequent Rights Offerings.    In addition to any Anti-Dilution Adjustments described above, if at any time we grant, issue or sell any Common Stock Equivalents or rights to purchase stock, warrants, securities or other property pro rata to the record holders of Common Stock or any class thereof (the “Purchase Rights”), then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder had held the number of shares of Common Stock acquirable upon complete conversion of such Holder’s Series J Convertible Preferred Stock (without regard to any limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights (provided, however, that, to the extent that the Holder’s right to participate in any such Purchase Right would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such Purchase Right to such extent (or beneficial ownership of such shares of Common Stock as a result of such Purchase Right to such extent) and such Purchase Right to such extent shall be held in abeyance for the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation).

Pro Rata Distributions. During such time as the Series J Convertible Preferred Stock is outstanding, if we declare or make any dividend or other distribution of our assets (or rights to acquire its assets) to holders of Common Stock, by way of return of capital or otherwise (including, without limitation, any distribution of cash, stock or other securities, property or options by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction) ( a “Distribution”), then, in each such case, the Holder shall be entitled to participate in such Distribution to the same extent that the Holder would have participated therein if the Holder had held the number of shares of Common Stock acquirable upon complete conversion of the Series J Convertible Preferred Stock (without regard to any limitations on conversion hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the date of which a record is taken for such Distribution, or, if no such record is taken, the date as of which the record holders of shares of our common stock are to be determined for the participation in such Distribution (provided, however, that, to the extent that the Holder’s right to participate in any such Distribution would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such Distribution to such extent (or in the beneficial ownership of any shares of Common Stock as a result of such Distribution to such extent) and the portion of such Distribution shall be held in abeyance for the benefit of the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation).

Fundamental Transactions.    In the event of a Fundamental Transaction (as defined in the Series J Certificate of Designation) and generally including any reorganization, recapitalization or reclassification of our common stock, the sale, transfer or other disposition of all or substantially all of our properties or assets, our consolidation or merger with or into another person, or the acquisition of more than 50% of our outstanding Common Stock, the holders of the Series J Convertible Preferred Stock will be entitled to receive upon conversion of the Series J Convertible Preferred Stock the kind and amount of securities, cash or other property that the holders would have received had they converted the Series J Convertible Preferred Stock immediately prior to such Fundamental Transaction (without regard to the Beneficial Ownership Limitation).

Mandatory Redemption.    If any shares of Series J Convertible Preferred Stock are outstanding at the end of the one (1) year term, then we shall promptly redeem all of such outstanding shares of Series J Convertible Preferred Stock on a pro rata basis among all of the Holders of Series J Convertible Preferred Stock commencing on the one-year anniversary of the original issue date in cash at a price per Series J Convertible Preferred Share equal to the sum of (x) 100% of the Stated Value plus (y) all other amounts due in respect of the Series J Convertible Preferred Stock (if any).

Limited Voting Rights.    Holders of the Series J Convertible Preferred Stock will not have any voting rights, except as described below or as otherwise required by law.

In any matter in which the Series J Convertible Preferred Stock may vote (as expressly provided herein or as may be required by law), each share of Series J Convertible Preferred Stock will be entitled to one vote per share. So long as any shares of Series J Convertible Preferred Stock remain outstanding, we will not, without the consent or the affirmative vote of a majority of the outstanding shares of Series J Convertible Preferred Stock, given in person or by proxy, either in writing without a meeting or by vote at any meeting called for the purpose:

•        alter or change adversely the powers, preferences or rights given to the Series J Convertible Preferred Stock or alter or amend the Series J Certificate of Designation;

•        increase the number of authorized shares of Series J Convertible Preferred Stock; or

•        enter into any agreement with respect to any of the foregoing.

The rules and procedures for calling and conducting any meeting of the holders of the Series J Convertible Preferred Stock (including, without limitation, the fixing of a record date in connection therewith), the solicitation and use of proxies at such a meeting, the obtaining of written consents and any other aspect or matter with regard to such a meeting or such consents shall be governed by any rules the Board (or a duly authorized committee of the Board), in its discretion, may adopt from time to time, which rules and procedures shall conform to the requirements of the Charter, Bylaws, applicable law and any national securities exchange or other trading facility on which the Series J Convertible Preferred Stock may be listed or traded at the time.

Holders of the Series J Convertible Preferred Stock will not have any voting rights with respect to, and the consent of the holders of the Series J Convertible Preferred Stock is not required for, the taking of any corporate action, including any merger or consolidation involving us or a sale of all or substantially all of our assets, regardless of the effect that such merger, consolidation or sale may have upon the powers, preferences, voting power or other rights or privileges of the Series J Convertible Preferred Stock, except as described above.

No Preemptive Rights.    No holders of the Series J Convertible Preferred Stock will, as holders of Series J Convertible Preferred Stock, have any preemptive rights to purchase or subscribe for the Common Stock or any other security.

Exclusion of Other Rights.    The shares of the Series J Convertible Preferred Stock do not have any voting powers, preferences or relative, participating, optional or other special rights, or qualifications, limitations or restrictions thereof, other than as set forth in the Series J Certificate of Designation or in our Charter.

Registration; Transfer.    Pursuant to the terms of the Series J Certificate of Designation, we are obligated to maintain an effective registration statement covering: (a) the issuance of shares of Common Stock issuable upon conversion of the Series J Convertible Preferred Stock and (b) the issuance of additional shares of Series J Convertible Preferred Stock pursuant to our obligation to pay Series J PIK dividends, in each case, until such time as no Series J Convertible Preferred Stock (and no Warrants exercisable for shares of Series J Convertible Preferred Stock) remain outstanding, unless there is available an exemption from, or a transaction not subject to, the registration requirements of the Securities Act that covers the issuance of the Series J Convertible Preferred Stock and the shares of Common Stock issuable upon conversion of such shares of Series J Convertible Preferred Stock.

Anti-Takeover Provisions of Delaware Law and Our Governing Documents

Delaware Law

We are incorporated in the State of Delaware. As a result, we are subject to Section 203 of the Delaware General Corporation Law, which prohibits a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years after the time that such stockholder became an interested stockholder, with the following exceptions:

•        before such time, the board of directors of the corporation approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder;

•        upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the voting

stock outstanding (but not the outstanding voting stock owned by the interested stockholder) those shares owned (1) by persons who are directors and also officers and (2) employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or

•        at or subsequent to such time, the business combination is approved by the board of directors and authorized at an annual or special meeting of the stockholders, and not by written consent, by the affirmative vote of at least 66 2/3% of the outstanding voting stock that is not owned by the interested stockholder.

In general, Section 203 defines a “business combination” to include the following:

•        any merger or consolidation involving the corporation or a direct or indirect majority-owned subsidiary of the corporation and the interested stockholder;

•        any sale, lease, mortgage, pledge transfer, or other disposition of the assets of the corporation or direct or indirect majority-owned a subsidiary of the corporation to or with the interested stockholder, which assets have an aggregate value equal to 10% or more of the fair value of the assets on a consolidated basis or the aggregate market value of the outstanding stock of the corporation;

•        subject to certain exceptions, any transaction that results in the issuance or transfer by the corporation or a direct or indirect majority-owned subsidiary of the corporation of any stock of the corporation or subsidiary to the interested stockholder;

•        any transaction involving the corporation or direct or indirect majority-owned subsidiary of the corporation that has the effect of increasing the proportionate share of the stock or any class or series of the corporation or the subsidiary beneficially owned by the interested stockholder; or

•        the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits by or through the corporation or direct or indirect majority-owned subsidiary of the corporation.

In general, under Section 203 defines an “interested stockholder” include an entity or person (other than the corporation any direct or indirect majority-owned subsidiary of the corporation) who, together with the person’s affiliates and associates, beneficially owns, 15% or more of the outstanding voting stock of the corporation. A Delaware corporation may “opt out” of these provisions with an express provision in its certificate of incorporation. Since we have not opted out of Section 203, Section 203 may discourage or prevent mergers or other takeover or change of control attempts of us.

Undesignated Preferred Stock

The ability to authorize undesignated preferred stock makes it possible for our Board to issue one or more series of preferred stock with voting or other rights or preferences. Thus, our Board could authorize the issuance of shares of preferred stock that have priority over our common stock with respect to dividends or rights upon liquidation or with terms and conditions that could have the effect of delaying, deferring or preventing a transaction or a change of control of our Company that might involve a premium price for holders of our common stock or otherwise be in their best interests.

Requirements for Advance Notification of Stockholder Nominations and Proposals

Our Bylaws establish advance notice procedures with respect to stockholder proposals and the nomination of candidates for election as directors, other than nominations made by or at the direction of the Board or a committee of the Board.

Stockholder Action by Written Consent; Special Meetings of Stockholders

Our stockholders may take action by written consent in lieu of a meeting as provided in our Bylaws. Our Bylaws provide that certain procedures, including notifying the Board and awaiting a record date, must be followed for stockholders to act by written consent. A special meeting of our stockholders may be called only by our Board, the Chairman of the

Board, the Chief Executive Officer or the President. A special meeting may also be called at the request of stockholders holding a majority of the aggregate number of shares of our capital stock issued and outstanding and entitled to vote at that meeting (subject to certain timeliness and content requirements of the demand).

Amendment of Charter and Bylaws

Our Charter may be amended by the affirmative vote of a majority of the aggregate number of shares of each class of our capital stock issued and outstanding after a resolution of our Board declaring the advisability of such amendment has been adopted in accordance with Delaware law. Our Bylaws may be amended by the affirmative vote of a majority of the aggregate number of shares of each class of our capital stock issued and outstanding (and entitled to vote on the subject matter) present in person or represented by proxy at a meeting of stockholders provided that notice thereof is stated in the written notice of the meeting. Our Bylaws may also be amended by a majority of the Board in accordance with Delaware law and our Charter, except that certain sections of our Bylaws (including but not limited to certain provisions regarding special meetings, voting, officers and approval of securities issuances) require either the affirmative vote of two-thirds of the persons then serving as directors on the Board or our stockholders.

Forum Selection

Unless the Board acting on behalf of the Company selects an alternative forum, the Court of Chancery of the State of Delaware (or, if the Court of Chancery does not have jurisdiction, another state court located within the State of Delaware or, if no court located within the State of Delaware has jurisdiction, the federal district court for the District of Delaware) shall be the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of the Company, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers or other employees to the Company or our stockholders, (iii) any action asserting a claim against the Company or any of our directors, officers or other employees arising pursuant to any provision of the DGCL, our Charter or our Bylaws or (iv) any action asserting a claim against the Company or any of our directors, officers or other employees governed by the internal affairs doctrine of the State of Delaware.

Common Stock

The material terms of our common stock are described under the caption “Description of our Capital Stock” in this prospectus.

Class C Warrants and Class D Warrants

Warrants Included in the Units and Pre-Funded Units

The following summary of certain terms and provisions of the Class C Warrants and Class D Warrants included in the Units and Pre-Funded Units that are being offered hereby is not complete and is subject to, and qualified in its entirety by, the provisions of the forms of the Class C Warrant and Class D Warrant, which are filed as exhibits to the registration statement of which this prospectus forms a part. Prospective investors should carefully review the terms and provisions set forth in forms of Warrants.

Warrant Stockholder Approval

Under Nasdaq listing rules, the exercisability of the Class C Warrants and Class D Warrants will not be effective until, and unless, we obtain the approval of our stockholders. While we intend to promptly seek stockholder approval, and in no event later than 90 days following the closing of this offering, there is no guarantee that the Warrant Stockholder Approval will ever be obtained. If we are unable to obtain the Warrant Stockholder Approval, the Warrants will not be able to be exercised and will therefore have no value. In addition, we will incur substantial costs, and management will devote substantial time and attention, in attempting to obtain the Warrant Stockholder Approval.

Warrant Agent.    The Warrants will be issued in accordance with a warrant agency agreement to be entered into between us and Computershare Trust Company, N.A.

Exercisability.    The Class C Warrants and Class D Warrants will become exercisable beginning on the date of the Warrant Stockholder Approval and at any time up to the date that is five years from the Warrant Stockholder Approval date (with respect to the Class C Warrants) or one year from the Warrant Stockholder Approval date (with respect to the

Class D Warrants). If Warrant Stockholder Approval is obtained, the Class C Warrants and Class D Warrants will be exercisable, at the option of each holder, in whole or in part by delivering to us a duly executed exercise notice and by payment in full in immediately available funds for the number of shares of common stock purchased upon such exercise. If a registration statement registering the issuance of the shares of common stock underlying the Class C Warrants or Class D Warrants under the Securities Act is not effective, the holder may elect to exercise the Class C Warrants or Class D Warrants through a cashless exercise, in which case the holder would receive upon such exercise the net number of shares of common stock determined according to the formula set forth in the warrant. No fractional shares of common stock will be issued in connection with the exercise of Class C Warrants or Class D Warrants. In lieu of fractional shares, we will pay the holder an amount in cash equal to the fractional amount multiplied by the exercise price.

Alternative Cashless Exercise.    A holder may also effect an “alternative cashless exercise” at any time while the Class D Warrants are exercisable and outstanding. Under the “alternative cashless exercise” option of the Class D Warrants, each holder of a Class D Warrant has the right to receive an aggregate number of shares equal to the product of (i) the aggregate number of shares of common stock that would be issuable upon a cash exercise of the Class D Warrant and (ii) [•].

Exercise Limitation.    A holder will not have the right to exercise any portion of the Class C Warrants or Class D Warrants if the holder (together with its affiliates) would beneficially own in excess of 4.99% of the number of shares of our common stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the Class C Warrants and Class D Warrants. However, any holder may increase or decrease such percentage to any other percentage not in excess of 9.99%, provided that any increase in such percentage shall not be effective until 61 days following notice from the holder to us.

Exercise Price.    The exercise price per whole share of common stock purchasable upon exercise of the Class C Warrants is equal to [•]% of the public offering price per Unit in this offering, and the exercise price per whole share of common stock purchasable upon exercise of the Class D Warrants is equal to [•]% of the public offering price per Unit in this offering. The exercise price of the Class C Warrants and Class D Warrants is subject to appropriate adjustment in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications or similar events affecting our common stock and also upon any distributions of assets, including cash, stock or other property to our stockholders.

Subsequent Equity Sales.    Subject to certain exemptions, if we sell, enter into an agreement to sell, or grant any option to purchase, or sell, enter into an agreement to sell, or grant any right to reprice (excluding Exempt Issuances, as defined in the Placement Agency Agreement), or otherwise dispose of or issue (or announce any offer, sale, grant or any option to purchase or other disposition) any shares of common stock, at an effective price per share less than the exercise price of the Class C Warrants then in effect, the exercise price of the Class C Warrants will be reduced to the lower of such price or the lowest VWAP during the five (5) consecutive trading days immediately following such dilutive issuance or announcement thereof (the “Base Share Price”), and the number of shares issuable upon exercise will be proportionately adjusted such that the aggregate exercise price will remain unchanged; provided that the Base Share Price shall not be less than $[___] (subject to adjustment for reverse and forward stock splits, recapitalizations and similar transactions following the date of the placement agency agreement) (the “Floor Price”).

Share Combination Event Adjustment.    If at any time on or after the date of issuance there occurs any stock split, stock dividend, stock combination recapitalization or other similar transaction involving our common stock and the lowest VWAP during the period commencing five consecutive trading days immediately preceding and the five consecutive trading days commencing on the date of such event is less than the exercise price of the Class C Warrants or Class D Warrants then in effect, then the exercise price of the Class C Warrants and Class D Warrants will be reduced to the lowest VWAP during such period and the number of shares issuable upon exercise will be proportionately adjusted such that the aggregate price will remain unchanged.

Transferability.    Subject to applicable laws, the Class C Warrants and Class D Warrants may be offered for sale, sold, transferred or assigned without our consent.

Fundamental Transactions.    In the case of certain fundamental transactions affecting the Company, a holder of Warrants, upon exercise of such Warrants after such fundamental transaction, will have the right to receive, in lieu of shares of our common stock, the same amount and kind of securities, cash or property that such holder would have been entitled to receive upon the occurrence of the fundamental transaction, had the Warrants been exercised immediately prior to such fundamental transaction. In lieu of such consideration, a holder of Warrants may instead elect to receive a cash payment based upon the Black-Scholes value of their Warrants.

Rights as a Stockholder.    Except as otherwise provided in the Class C Warrants or Class D Warrants or by virtue of such holder’s ownership of shares of our common stock, the holder of Class C Warrants or Class D Warrants does not have the rights or privileges of a holder of our common stock, including any voting rights, until the holder exercises the Class C Warrants or Class D Warrants.

Governing Law.    The Class C Warrants and the Class D Warrants are governed by New York law.

No Listing.    We do not intend to list the Warrants on any securities exchange or nationally recognized trading system. Except as otherwise provided in the Warrants or by virtue of such holder’s ownership of shares of our common stock, the holders of the Warrants do not have the rights or privileges of holders of our common stock, including any voting rights, until they exercise their Warrants.

Stockholder Meeting.    In addition, we have agreed to hold a special meeting of stockholders (which may also be at the annual meeting of shareholders) at the earliest practicable date after the date hereof, but in no event later than ninety days after the closing of the offering, in order to obtain Warrant Stockholder Approval.

Pre-Funded Warrants Included in the Pre-Funded Units

The following summary of certain terms and provisions of the Pre-Funded Warrants offered hereby is not complete and is subject to, and qualified in its entirety by, the provisions of the form of Pre-Funded Warrant, which is filed as an exhibit to the registration statement of which this prospectus forms a part. Prospective investors should carefully review the terms and provisions set forth in the form of Pre-Funded Warrant.

The term “pre-funded” refers to the fact that the purchase price of our common stock in this offering includes almost the entire exercise price that will be paid under the Pre-Funded Warrants, except for a nominal remaining exercise price of $0.001. The purpose of the Pre-Funded Warrants is to enable investors that may have restrictions on their ability to beneficially own more than 4.99% (or, upon election of the holder, 9.99%) of our outstanding common stock following the consummation of this offering the opportunity to make an investment in the Company without triggering their ownership restrictions, by receiving Pre-Funded Warrants in lieu of our common stock which would result in such ownership of more than 4.99% (or 9.99%), and receive the ability to exercise their option to purchase the shares underlying the Pre-Funded Warrants at such nominal price at a later date.

The Pre-Funded Warrants will be issued in accordance with a warrant agency agreement to be entered into between us and Computershare Trust Company, N.A.

Exercise of Pre-Funded Warrants.    Each Pre-Funded Warrant is exercisable for one share of our common stock, with an exercise price equal to $0.001 per share, at any time that the Pre-Funded Warrant is outstanding. There is no expiration date for the Pre-Funded Warrants. The holder of a Pre-Funded Warrant will not be deemed a holder of our underlying common stock until the Pre-Funded Warrant is exercised.

Exercise Limitation.    Subject to limited exceptions, a holder of Pre-Funded Warrants will not have the right to exercise any portion of its Pre-Funded Warrants if the holder (together with such holder’s affiliates, and any persons acting as a group together with such holder or any of such holder’s affiliates) would beneficially own a number of shares of common stock in excess of 4.99% (or, at the election of the purchaser prior to the date of issuance, 9.99%) of the common stock then outstanding after giving effect to such exercise.

Exercise Price.    The exercise price and the number of shares of common stock issuable upon exercise of the Pre-Funded Warrants is subject to appropriate adjustment in the event of recapitalization events, stock dividends, stock splits, stock combinations, reclassifications, reorganizations or similar events affecting our common stock. The Pre-Funded Warrant holders must pay the exercise price in cash upon exercise of the Pre-Funded Warrants.

Transferability.    Subject to applicable laws, the Pre-Funded Warrants may be offered for sale, sold, transferred or assigned without our consent.

No Listing.    There is no established public trading market for the Pre-Funded Warrants and we do not expect a market to develop. In addition, we do not intend to apply for listing of the Pre-Funded Warrants on any securities exchange or trading system. Without an active market, the liquidity of the Pre-Funded Warrants will be limited.

Fundamental Transactions.    In the event of a “fundamental transaction,” as defined in the Pre-Funded Warrants and generally including any reorganization, recapitalization or reclassification of our common stock, the sale, transfer or other disposition of all or substantially all of our properties or assets, our consolidation or merger with or into another person, the acquisition of more than 50% of our outstanding common stock, or any person or group becoming the beneficial owner of 50% of the voting power represented by our outstanding common stock, the holders of the Pre-Funded Warrants will be entitled to receive upon exercise of the Pre-Funded Warrants the kind and amount of securities, cash or other property that the holders would have received had they exercised the Pre-Funded Warrants immediately prior to such fundamental transaction.

Rights as a Stockholder.    Prior to the exercise of any Pre-Funded Warrants to purchase common stock, holders of the Pre-Funded Warrants will not have any of the rights of holders of common stock purchasable upon exercise, including the right to vote, except as set forth therein.

Governing Law.    The Pre-Funded Warrants are governed by New York law.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES

The following is a general discussion of the material U.S. federal income tax considerations applicable to the ownership and disposition of shares of our common stock and Warrants acquired in this offering. This discussion is for general information only and is not tax advice. Accordingly, all prospective holders of our common stock and Warrants should consult their own tax advisors with respect to the U.S. federal, state, local and non-U.S. tax consequences of the purchase, ownership and disposition of our common stock and Warrants. This discussion is based on current provisions of the U.S. Internal Revenue Code of 1986, as amended, which we refer to as the Code, existing and proposed U.S. Treasury Regulations promulgated thereunder, current administrative rulings and judicial decisions, all as in effect as of the date of this prospectus, all of which are subject to change or to differing interpretation, possibly with retroactive effect. Any change could alter the tax consequences described in this prospectus. We assume in this discussion that each holder holds shares of our common stock and Warrants as capital assets within the meaning of Section 1221 of the Code (generally property held for investment).

This discussion does not address all aspects of U.S. federal income taxation that may be relevant to a particular holder in light of that holder’s individual circumstances, does not address the alternative minimum or Medicare contribution taxes, and does not address any aspects of U.S. state, local or non-U.S. taxes or any U.S. federal taxes other than income tax. This discussion also does not consider any specific facts or circumstances that may apply to a holder and does not address aspects of U.S. federal income taxation that may be applicable to holders that are subject to special tax rules, including without limitation:

•        insurance companies;

•        tax-exempt organizations;

•        financial institutions;

•        brokers or dealers in securities;

•        regulated investment companies;

•        real estate investment trusts;

•        pension plans, individual retirement accounts and other tax deferred accounts;

•        persons that mark their securities to market;

•        controlled foreign corporations;

•        passive foreign investment companies;

•        “dual resident” corporations;

•        persons that receive our common stock or Warrants as compensation for the performance of services;

•        owners that hold our common stock or Warrants as part of a straddle, hedge, conversion transaction, synthetic security or other integrated investment;

•        owners that own, or are deemed to own, more than 5% of our capital stock (except to the extent specifically set forth below);

•        persons that have a functional currency other than the U.S. dollar; and

•        certain U.S. expatriates.

In addition, this discussion does not address the tax treatment of partnerships (including an entity or arrangement treated as a partnership for U.S. federal income tax purposes) or other pass-through entities for U.S. federal income tax purposes, or persons who hold our common stock or Warrants through partnerships or other pass-through entities for U.S. federal income tax purposes. A partner in a partnership (including an entity or arrangement treated as a

partnership for U.S. federal income tax purposes) or other pass-through entity that will hold our common stock or Warrants should consult his, her or its own tax advisor regarding the tax consequences of acquiring, holding and disposing of our common stock or Warrants through a partnership or other pass-through entity, as applicable.

As used in this prospectus, the term “U.S. holder” means a beneficial owner of common stock or Warrants that is for U.S. federal income tax purposes:

•        a citizen or individual resident of the United States;

•        a corporation (or other entity properly classified as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States, any state within the United States, or the District of Columbia;

•        an estate, the income of which is subject to U.S. federal income taxation regardless of its source; or

•        a trust, if (i) a U.S. court is able to exercise primary supervision over the trust’s administration and one or more “United States persons” (as defined in the Code) have the authority to control all substantial decisions of the trust, or (ii) in the case of a trust that was treated as a domestic trust under the laws in effect before 1997, a valid election is in place under applicable U.S. Treasury regulations to treat such trust as a domestic trust.

The term “non-U.S. holder” means any beneficial owner of shares of common stock or Warrants that is not a U.S. holder and is not a partnership or other entity properly classified as a partnership for U.S. federal income tax purposes. For the purposes of this prospectus, U.S. holders and non-U.S. holders are referred to collectively as “holders.” There can be no assurance that the Internal Revenue Service, which we refer to as the IRS, will not challenge one or more of the tax consequences described herein. We have not obtained, nor do we intend to obtain, a ruling from the IRS with respect to the U.S. federal income tax consequences of the purchase, ownership or disposition of our common stock or Warrants.

Treatment of Pre-Funded Warrants

Although it is not entirely free from doubt, a Pre-Funded Warrant should be treated as a share of our common stock for U.S. federal income tax purposes and a holder of Pre-Funded Warrants should generally be taxed in the same manner as a holder of common stock, as described below.

Accordingly, no gain or loss should be recognized upon the exercise of a Pre-Funded Warrant and, upon exercise, the holding period of a Pre-Funded Warrant should carry over to the share of common stock received. Similarly, the tax basis of the Pre-Funded Warrant should carry over to the share of common stock received upon exercise, increased by the exercise price of $0.01 per share. Each holder should consult his, her or its own tax advisor regarding the risks associated with the acquisition of Pre-Funded Warrants pursuant to this offering (including potential alternative characterizations). The balance of this discussion generally assumes that the characterization described above will be respected for U.S. federal income tax purposes.

Treatment of Units and Pre-Funded Units

The purchase price for each Unit will be allocated between each share of common stock and accompanying Warrant in proportion to their relative fair market values at the time the Unit is purchased by the holder. Similarly, the purchase price for each Pre-Funded Unit will be allocated between each Pre-Funded Warrant (which, as described above, should generally be treated as a share of our common stock for U.S. federal income tax purposes) and accompanying Warrant in proportion to their relative fair market values at the time the Pre-Funded Unit is purchased by the holder. This allocation will establish a holder’s initial tax basis for U.S. federal income tax purposes in his, her or its share of common stock (or, in lieu of common stock, Pre-Funded Warrant) and Warrant included in each investment unit. We will not be providing holders with such allocation, and it is possible that different holders will reach different determinations regarding such allocation. A holder’s allocation of purchase price between each share of common stock (or, in lieu of common stock, each Pre-Funded Warrant) and the accompanying Warrant is not binding on the IRS or the courts, and no assurance can be given that the IRS or the courts will agree with a holder’s allocation.

Accordingly, each prospective holder should consult his, her or its own tax advisor with respect to the allocation, and the risks associated with such allocation, of the holder’s purchase price for the investment unit between our shares of common stock (or, in lieu of common stock, Pre-Funded Warrants) and Warrants.

Tax Consequences to U.S. Holders

Exercise or Expiration of Warrants

Subject to the discussion below with respect to the cashless exercise of a Warrant, a U.S. holder will not recognize income, gain or loss on the exercise of a Warrant. A U.S. holder’s tax basis in the common stock received upon the exercise of a Warrant will equal the sum of (i) the initial tax basis of the Warrant exercised (as determined pursuant to the rules discussed above under “Treatment of Units and Pre-Funded Units”) and (ii) the exercise price of the Warrant. The U.S. holder’s holding period for the common stock received upon exercise of a Warrant will begin on the day after such exercise (or possibly on the date of exercise) and will not include the period during which the U.S. holder held the Warrant.

If a registration statement registering the issuance of the common stock underlying the Warrants under the Securities Act is not effective or available the holder may, in its sole discretion, elect to exercise the Warrant through a cashless exercise. The tax consequences of a cashless exercise of a Warrant are not clear under current U.S. tax law. U.S. holders should consult their own tax advisors regarding the tax consequences of a cashless exercise.

If a Warrant is allowed to lapse unexercised, a U.S. holder generally will recognize a capital loss equal to such holder’s tax basis in the Warrant. The deductibility of capital losses is subject to significant limitations.

Distributions on Our Common Stock

We have never paid cash dividends on our common stock and we do not anticipate paying any cash dividends in the foreseeable future. See “Dividend Policy.” If we do make distributions on our common stock to a U.S. holder, those distributions generally will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits as determined under U.S. federal income tax principles. If a distribution exceeds our current and accumulated earnings and profits, the excess will be treated as a tax-free return of the U.S. holder’s investment, up to (and in reduction of) such U.S. holder’s tax basis in the common stock. Any remaining excess will be treated as capital gain, subject to the tax treatment described below in “— Sale, Exchange or Other Taxable Disposition of Our Common Stock or Warrants.” Dividends paid by us generally will be eligible for the reduced rates of tax for qualified dividend income allowed to individual U.S. holders and for the dividends received deduction allowed to corporate U.S. holders, in each case assuming that certain holding period and other requirements are satisfied.

Constructive Distributions on Our Warrants

Under Section 305 of the Code, an adjustment to the number of shares of common stock that will be issued on the exercise of our Warrants (whether Pre-Funded Warrants or Warrants), or an adjustment to the exercise price of such Warrants, may be treated as a constructive distribution to a U.S. Holder of the Warrants if, and to the extent that, such adjustment has the effect of increasing such U.S. Holder’s proportionate interest in our “earnings and profits” or assets, depending on the circumstances of such adjustment (for example, if such adjustment is to compensate for a distribution of cash or other property to holders of our common stock). Adjustments to the exercise price of a Warrant made pursuant to a bona fide reasonable adjustment formula that has the effect of preventing dilution of the interest of the holder of the Warrant should generally not result in a constructive distribution. Any constructive distributions generally would be subject to the tax treatment described above under “— Distributions on our Common Stock”.

Sale, Exchange or Other Taxable Disposition of Our Common Stock or Warrants

Upon the sale, exchange, or other taxable disposition of our common stock or Warrants (whether Pre-Funded Warrants or Warrants), a U.S. holder will recognize gain or loss equal to the difference between the amount realized upon the disposition and the U.S. holder’s tax basis in the common stock or Warrants sold or exchanged.

Any gain or loss generally will be capital gain or loss, and will be long-term capital gain or loss if the U.S. holder’s holding period for the common stock or Warrants exceeded one year at the time of the disposition. Certain U.S. holders (including individuals) are currently eligible for preferential rates of U.S. federal income taxation in respect of long-term capital gains. The deductibility of capital losses is subject to significant limitations.

Information Reporting and Backup Withholding

In general, information reporting requirements may apply to distributions (whether actual or constructive) paid to a U.S. holder on our common stock or Warrants, and to the proceeds of the sale, exchange or other disposition of our common stock and Warrants, unless the U.S. holder is an exempt recipient. Backup withholding will apply to such payments if the U.S. holder fails to provide a taxpayer identification number, a certification of exempt status or has been notified by the IRS that it is subject to backup withholding (and such notification has not been withdrawn). Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against a U.S. holder’s U.S. federal income tax liability provided the required information is timely furnished to the IRS.

Tax Consequences to Non-U.S. Holders

Exercise or Expiration of Warrants

In general, a non-U.S. holder will not be required to recognize income, gain or loss upon the exercise of a Warrant by payment of the exercise price. To the extent that a cashless exercise results in a taxable exchange, the consequences would be similar to those described below under “Sale, Exchange or Other Taxable Disposition of our Common Stock or Warrants”.

The expiration of a Warrant will be treated as if the non-U.S. holder sold or exchanged the Warrant and recognized a capital loss equal to the non-U.S. holder’s basis in the Warrant. A non-U.S. holder will not be able to utilize a loss recognized upon expiration of a Warrant against the Non-U.S. holder’s U.S. federal income tax liability, however, unless the loss (i) is effectively connected with the non-U.S. holder’s conduct of a trade or business within the United States (and, if an income tax treaty applies, is attributable to a “permanent establishment” or “fixed base” in the United States) or (ii) is treated as a U.S. source loss and the non-U.S. holder is present in the United States 183 days or more in the taxable year of disposition and certain other conditions are met.

Distributions on Our Common Stock

We have never paid cash dividends on our common stock and we do not anticipate paying any cash dividends in the foreseeable future. See “Dividend Policy.” If we do make distributions to holders of our common stock or if we are treated as making a constructive distribution to holders of our Warrants or Pre-Funded Warrants, those distributions generally will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. If a distribution exceeds our current and accumulated earnings and profits, the excess will be treated as a tax-free return of the non-U.S. holder’s investment, up to such non-U.S. holder’s tax basis in the common stock. Any remaining excess will be treated as capital gain, subject to the tax treatment described below in “— Sale, Exchange or Other Taxable Disposition of Our Common Stock or Warrants.”

Distributions (including constructive distributions) made to a non-U.S. holder that are treated as dividends generally will be subject to withholding of U.S. federal income tax at a rate of 30% of the gross amount or such lower rate as may be specified by an applicable income tax treaty between the United States and such holder’s country of residence, unless such dividends are effectively connected with a trade or business conducted by a non-U.S. holder within the United States (as discussed below). A non-U.S. holder of our common stock who claims the benefit of an applicable income tax treaty between the United States and such holder’s country of residence generally will be required to provide a properly executed IRS Form W-8BEN or W-8BEN-E (or successor form), as applicable, and satisfy applicable certification and other requirements. Non-U.S. holders are urged to consult their own tax advisors regarding their entitlement to benefits under a relevant income tax treaty. A non-U.S. holder that is eligible for a reduced rate of U.S. withholding tax under an income tax treaty may be able to obtain a refund or credit of any excess amounts withheld by timely filing the required information with the IRS.

Dividends that are treated as effectively connected with a trade or business conducted by a non-U.S. holder within the United States and, if an applicable income tax treaty so provides, that are attributable to a “permanent establishment” or a “fixed base” maintained by the non-U.S. holder within the United States, generally are exempt from the 30% withholding tax if the non-U.S. holder satisfies applicable certification and disclosure requirements.

U.S. effectively connected income, net of specified deductions and credits, is generally taxed at the same graduated U.S. federal income tax rates applicable to United States persons (as defined in the Code). Any U.S. effectively connected income received by a non-U.S. holder that is a corporation may also be subject to an additional “branch profits tax” at a 30% rate or such lower rate as may be specified by an applicable income tax treaty between the United States and such holder’s country of residence.

Constructive Distributions on Our Warrants

As described above under “— Tax Consequences to U.S. Holders — Constructive Distributions on our Warrants,” an adjustment to the Warrants could result in a constructive distribution to a non-U.S. holder, which would be treated as described under “— Distributions on Our Common Stock” above. Any resulting withholding tax attributable to deemed dividends would be collected from other amounts payable or distributable to the non-U.S. holder. Non-U.S. holders should consult their tax advisors regarding the proper treatment of any adjustments to the Warrants.

In addition, regulations governing “dividend equivalents” under Section 871(m) of the Code may apply to the Pre-Funded Warrants. Under those regulations, an implicit or explicit payment made to the holder of Pre-Funded Warrants that references a distribution on our common stock would generally be taxable to a non-U.S. holder in the manner described under “Distributions on our Common Stock” above. Such dividend equivalent amount would be taxable and subject to withholding whether or not there is actual payment of cash or other property, and we may satisfy any withholding obligations by withholding from other amounts due to the non-U.S. holder. Non-U.S. holders are encouraged to consult their own tax advisors regarding the application of Section 871(m) of the Code to the Pre-Funded Warrants.

Sale, Exchange or Other Taxable Disposition of Our Common Stock or Warrants

In general, a non-U.S. holder will not be subject to any U.S. federal income tax on any gain realized upon such holder’s sale, exchange or other taxable disposition of shares of our common stock or Warrants (whether Pre-Funded Warrants or Warrants) unless:

•        the gain is effectively connected with the non-U.S. holder’s conduct of a U.S. trade or business and, if an applicable income tax treaty so provides, is attributable to a “permanent establishment” or a “fixed base” maintained by such non-U.S. holder in the United States, in which case the non-U.S. holder generally will be taxed on such gain at the graduated U.S. federal income tax rates applicable to United States persons (as defined in the Code) and, if the non-U.S. holder is a foreign corporation, the branch profits tax described above in “— Tax Consequences to Non-U.S. Holders — Distributions on Our Common Stock” also may apply to such gain;

•        the non-U.S. holder is a nonresident alien individual who is present in the United States for 183 days or more in the taxable year of the taxable disposition and certain other conditions are met, in which case the non-U.S. holder will be subject to a 30% tax (or such lower rate as may be specified by an applicable income tax treaty between the United States and such holder’s country of residence) on the net gain derived from the taxable disposition, which may be offset by certain U.S. source capital losses of the non-U.S. holder, if any; or

•        we are, or have been, at any time during the five-year period preceding such taxable disposition (or the non-U.S. holder’s holding period, if shorter) a “U.S. real property holding corporation,” unless our common stock is regularly traded on an established securities market and the non-U.S. holder holds no more than 5% of our outstanding common stock, directly or indirectly, during the shorter of the 5-year period ending on the date of the taxable disposition or the period that the non-U.S. holder held our common stock. Generally, a corporation is a U.S. real property holding corporation only if the fair market value of its U.S. real property interests equals or exceeds 50% of the sum of the fair market value of its worldwide real property interests plus its other assets used or held for use in a trade or business. Although there can be no assurance, we do not believe that we are, or have been, a U.S. real property holding corporation, or that we are likely to become one in the future. No assurance can be provided that our common stock will be regularly traded on an established securities market for purposes of the rules described above.

Information Reporting and Backup

Withholding

We must report annually to the IRS and to each non-U.S. holder the gross amount of the distributions paid on our common stock (and constructive distributions on our Warrants) to such holder and the tax withheld, if any, with respect to such distributions. Non-U.S. holders may have to comply with specific certification procedures to establish that the holder is not a United States person (as defined in the Code) in order to avoid backup withholding at the applicable rate with respect to dividends on our common stock or Warrants. Dividends paid to non-U.S. holders subject to the U.S. withholding tax, as described above in “Non-U.S. Holders — Distributions on Our Common Stock,” generally will be exempt from U.S. backup withholding.

Information reporting and backup withholding generally will apply to the proceeds of a disposition of our common stock and Warrants by a non-U.S. holder effected by or through the U.S. office of any broker, U.S. or foreign, unless the holder certifies its status as a non-U.S. holder and satisfies certain other requirements, or otherwise establishes an exemption. Generally, information reporting and backup withholding will not apply to a payment of disposition proceeds to a non-U.S. holder where the transaction is effected outside the United States through a non-U.S. office of a broker. However, for information reporting purposes, dispositions effected through a non-U.S. office of a broker with substantial U.S. ownership or operations generally will be treated in a manner similar to dispositions effected through a U.S. office of a broker. Non-U.S. holders should consult their own tax advisors regarding the application of the information reporting and backup withholding rules to them.

Copies of information returns may be made available to the tax authorities of the country in which the non-U.S. holder resides or is incorporated under the provisions of a specific treaty or agreement.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules from a payment to a non-U.S. holder can be refunded or credited against the non-U.S. holder’s U.S. federal income tax liability, if any, provided that an appropriate claim is filed with the IRS.

Foreign Accounts

The Foreign Account Tax Compliance Act, or FATCA, generally imposes a 30% withholding tax on dividends (including constructive dividends) on our common stock and Warrants if paid to a non-U.S. entity unless (i) if the non-U.S. entity is a “foreign financial institution,” the non-U.S. entity undertakes certain due diligence, reporting, withholding, and certification obligations, (ii) if the non-U.S. entity is not a “foreign financial institution,” the non-U.S. entity identifies certain of its U.S. investors, if any, or (iii) the non-U.S. entity is otherwise exempt under FATCA.

Withholding under FATCA generally will apply to payments of dividends (including constructive dividends) on our common stock and Warrants.

An intergovernmental agreement between the United States and an applicable foreign country may modify the requirements described in this section. Under certain circumstances, a holder may be eligible for refunds or credits of the tax. While withholding described in this paragraph would have applied also to payments of gross proceeds from the sale or other disposition of our securities on or after January 1, 2019, proposed Treasury Regulations eliminate such withholding on payments of gross proceeds entirely. Taxpayers generally may rely on these proposed Treasury Regulations until final Treasury regulations are issued. Non-U.S. holders should consult their own tax advisors regarding the possible implications of FATCA on their investment in our common stock or Warrants. The preceding discussion of material U.S. federal income tax considerations is for informational purposes only. It is not tax advice. Prospective investors should consult their own tax advisors regarding the particular U.S. federal, state, local and non-U.S. tax consequences of purchasing, holding and disposing of our common stock or Warrants, including the consequences of any proposed changes in applicable laws.

PLAN OF DISTRIBUTION

We are offering on a best efforts basis up to [•] Units, at an assumed offering price of $ [•] per Unit pursuant to this prospectus, which represents the closing price of our common stock on the Nasdaq Capital Market on [•], 2024, for gross proceeds of up to $[•] million, before deduction of placement agent fees and offering expenses. We are also offering to those purchasers, if any, whose purchase of Units in this offering would otherwise result in the purchaser, together with its affiliates and related parties, beneficially owning more than 4.99% of our outstanding common stock immediately following the consummation of this offering, the opportunity to purchase, if they so choose, Pre-Funded Units in lieu of the Units that would otherwise result in ownership in excess of 4.99% (or, at the election of the purchaser, 9.99%). The offering price of each Pre-Funded Unit will equal the offering price per Unit, minus $0.001.

Because this is a best efforts offering, Maxim Group LLC, as placement agent, does not have an obligation to purchase any securities. We expect that the offering will end one trading day after we first enter into a securities purchase agreement relating to the offering and the offering will settle delivery versus payment (“DVP”)/receipt versus payment (“RVP”). Accordingly, we and the placement agent have not made any arrangements to place investor funds in an escrow account or trust account since the placement agent will not receive investor funds in connection with the sale of the securities offered hereunder.

Pursuant to a placement agency agreement dated [•], 2024, we have engaged Maxim Group LLC to act as our sole placement agent (the “placement agent”) to solicit offers to purchase the securities offered by this prospectus. The placement agent is not purchasing or selling any securities, nor is it required to arrange for the purchase and sale of any specific number or dollar amount of securities, other than to use its “reasonable best efforts” to arrange for the sale of the securities by us. Therefore, we may not sell the entire amount of securities being offered.

We will enter into a securities purchase agreement directly with the investors, at the investor’s option, who purchase our securities in this offering. Investors who do not enter into a securities purchase agreement shall rely solely on this prospectus in connection with the purchase of our securities in this offering. The placement agent may engage one or more subagents or selected dealers in connection with this offering.

The placement agency agreement provides that the placement agent’s obligations are subject to conditions contained in the placement agency agreement.

We will deliver the securities being issued to the investors upon receipt of investor funds for the purchase of the securities offered pursuant to this prospectus. We expect to deliver the securities being offered pursuant to this prospectus DVP/RVP on or about two trading days after we first enter into a securities purchase agreement relating to the offering.

Placement Agent Fees and Expenses

Upon the closing of this offering, we will pay the placement agent a cash transaction fee equal to 7.0% of the aggregate gross cash proceeds to us from the sale of the securities in the offering, and we agreed to reimburse the placement agent for certain out-of-pocket expenses of the placement agent payable by us, in an aggregate amount not to exceed $125,000.

The following table shows the public offering price, placement agent fees and proceeds, before expenses and assuming no exercise of the Warrants or the Pre-Funded Warrants, to us

We estimate that the total expenses of the offering, including registration, filing and listing fees, printing fees and legal and accounting expenses, but excluding the placement agent fees, will be approximately $560,000, all of which are payable by us. This figure includes, among other things, the placement agent’s legal fees and expenses and other out-of-pocket expenses in an amount up to $125,000.

Lock-Up Agreements

We have agreed not to, subject to certain exceptions, (i) offer, pledge, issue, sell, contract to sell, lend or otherwise transfer or dispose of, directly or indirectly, any shares of our common stock or any securities convertible into or exercisable or exchangeable for our common stock; (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of shares of our common stock; or (iii) file any registration statement with the SEC relating to the offering of any shares of our common stock or any securities convertible into or exercisable or exchangeable for shares of our common stock, other than with respect to the registration of shares of our common stock to be issued under an equity incentive plan, without the prior written consent of the placement agent for a period of 90 days following the date of this prospectus (the “Lock-Up Period”). This consent may be given at any time. These restrictions on future issuances are subject to exceptions for (i) the filing by the Company of a registration statement on Form S-4 or a registration statement on Form S-8 or a successor form thereto with respect to securities pursuant to any stock option, stock bonus or other stock plan or arrangement or the proposal or authorization of any increase in the Company’s authorized capital stock, (ii) the issuance of securities sold in this offering or upon the exercise of securities sold in this offering, (iii) the issuance of shares of our common stock upon the exercise of outstanding options or warrants, the vesting of outstanding restricted stock units or upon the conversion of outstanding securities, (iv) the issuance of employee stock options not exercisable during the Lock-Up Period and the grant or forfeiture of restricted stock awards or restricted stock units pursuant to our equity incentive plans or other arrangements described in this prospectus or the documents incorporated by reference herein and (v) the issuance of securities issued pursuant to certain acquisitions or strategic transactions not primarily for the purpose of raising capital.

In addition, our directors, executive officers and all stockholders of 5.0% or more of our common stock prior to this offering, including holders of securities convertible into or exercisable for shares of common stock, have entered into lock-up agreements with the placement agent. Under these agreements, these individuals have agreed, subject to certain specified exceptions, not to sell or transfer any shares of common stock or securities convertible into or exchangeable or exercisable for our shares of common stock during the Lock Up Period, without first obtaining the written consent of the placement agent. Specifically, these individuals have agreed, in part, not to:

(1)    offer, pledge, announce the intention to sell, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, make any short sale or otherwise transfer or dispose of, directly or indirectly, any shares of our common stock or any securities convertible into or exercisable or exchangeable for shares of our common stock (including without limitation, our common stock which may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the SEC and securities which may be issued upon exercise of a stock option or warrant), whether now owned or hereafter acquired (the “Undersigned’s Securities”);

(2)    enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Undersigned’s Securities;

whether any such transaction described in clause (1) or (2) above is to be settled by delivery of our common stock or such other securities, in cash or otherwise;

(3)    make any demand for or exercise any right with respect to the registration of any shares of our common stock or any security convertible into or exercisable or exchangeable for our common stock; or

(4)    publicly announce or disclose the intention to do any of the foregoing.

Indemnification

We have agreed to indemnify the placement agent against certain liabilities, including liabilities under the Securities Act, and to contribute to payments that the placement agent may be required to make for these liabilities.

Regulation M

The placement agent may be deemed to be an underwriter within the meaning of Section 2(a)(11) of the Securities Act, and any commissions received by them and any profit realized on the resale of the securities sold by them while acting as principal might be deemed to be underwriting discounts or commissions under the Securities Act. As an underwriter, the placement agent would be required to comply with the requirements of the Securities Act and the

Exchange Act, including, without limitation, Rule 10b-5 and Regulation M under the Exchange Act. These rules and regulations may limit the timing of purchases and sales of our securities by the placement agent acting as principal. Under these rules and regulations, the placement agent (i) may not engage in any stabilization activity in connection with our securities and (ii) may not bid for or purchase any of our securities or attempt to induce any person to purchase any of our securities, other than as permitted under the Exchange Act, until they have completed their participation in the distribution.

Determination of Offering Price and Warrant Exercise Price

The actual offering price of the securities we are offering, and the exercise price of the Warrants and Pre-Funded Warrants included in the Units and Pre-Funded Units that we are offering, were negotiated between us, the placement agent and the investors in the offering based on the trading of our shares of common stock prior to the offering, among other things. Other factors considered in determining the public offering price of the securities we are offering, as well as the exercise price of the Warrants and Pre-Funded Warrants that we are offering include our history and prospects, the stage of development of our business, our business plans for the future and the extent to which they have been implemented, an assessment of our management, the general conditions of the securities markets at the time of the offering and such other factors as were deemed relevant.

Electronic Distribution

A prospectus in electronic format may be made available on a website maintained by the placement agent. In connection with the offering, the placement agent or selected dealers may distribute prospectuses electronically. No forms of electronic prospectus other than prospectuses that are printable as Adobe® PDF will be used in connection with this offering.

Other than the prospectus in electronic format, the information on the placement agent’s website and any information contained in any other website maintained by the placement agent is not part of the prospectus or the registration statement of which this prospectus forms a part, has not been approved and/or endorsed by us or the placement agent in its capacity as placement agent and should not be relied upon by investors.

CHANGES IN INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Dismissal of Independent Registered Public Accounting Firm

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 13. Other Expenses of Issuance and Distribution.

The following table sets forth the estimated costs and expenses, other than underwriting discounts and commissions, payable by BIOLASE, Inc. (the “Registrant”) in connection with the offering of the securities being registered. All of the amounts shown are estimates except for the SEC registration fee and the FINRA filing fee.

Item 14. Indemnification of Directors and Officers.

Section 145 of the Delaware General Corporation Law (the “DGCL”) authorizes and empowers a Delaware corporation to indemnify its directors, officers, employees and agents against liabilities incurred in connection with, and related expenses resulting from, any claim, action or suit brought against any such person as a result of his or her relationship with the corporation, provided that such persons acted in good faith and in a manner such person reasonably believed to be in, and not opposed to, the best interests of the corporation in connection with the acts or events on which such claim, action or suit is based. Section 145 of the DGCL also authorizes corporations to purchase and maintain insurance on behalf of such persons so indemnified. The finding of either civil or criminal liability on the part of such person in connection with such acts or events is not necessarily determinative of the question of whether such person has met the required standard of conduct and is, accordingly, entitled to be indemnified.

Section 102(b)(7) of the DGCL enables a corporation in its certificate of incorporation or an amendment thereto to eliminate or limit the personal liability of a director to the corporation or its stockholders of monetary damages for violations of the directors’ fiduciary duty of care, except (i) for any breach of the director’s duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law, (iii) pursuant to Section 174 of the DGCL (providing for liability of directors for unlawful payment of dividends or unlawful stock purchases or redemptions) or (iv) for any transaction from which a director derived an improper personal benefit.

The Company’s Restated Certificate of Incorporation, as amended (the “charter”), provides that, to the extent permitted by applicable law, the registrant’s directors shall not be personally liable to the registrant or its stockholders for monetary damages for any breach of fiduciary duty as directors of the registrant. The charter eliminates the personal liability of directors to the fullest extent permitted by the DGCL. The Registrant’s Eighth Amended and Restated Bylaws (the “bylaws”) provide that each person who was or is made a party or is threatened to be made a party to or is involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that he or she, or a person of whom he or she is the legal representative, is or was a director or officer of the registrant shall be indemnified and held harmless by the registrant to the fullest extent authorized by the DGCL, against all costs, charges, expenses, liabilities and losses (including attorneys’ fees, judgments, fines, ERISA excise taxes or penalties and amounts paid or to be paid in settlement) reasonably incurred or suffered by such person in connection therewith, and such indemnification shall continue as to a person who has ceased to be a director or officer and shall inure to the benefit of his or her heirs, executors and personal or legal representatives. The Registrant has also obtained liability insurance for its officers and directors and has entered into indemnification agreements with its directors and officers. (including attorneys’ fees, judgments, fines, ERISA excise taxes or penalties and amounts paid or to be paid in settlement) reasonably incurred or suffered by such person in connection therewith, and such indemnification shall continue as to a person who has ceased

to be a director or officer and shall inure to the benefit of his or her heirs, executors and personal or legal representatives. The Registrant has also obtained liability insurance for its officers and directors and has entered into indemnification agreements with its directors and officers.

The foregoing statements are subject to the provisions of Sections 145 and 102(b)(7) of the DGCL, the Registrant’s bylaws and the Registrant’s charter, which bylaws and charter have been filed as exhibits to this registration statement.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling us pursuant to the foregoing provisions, we have been informed that, in the opinion of the SEC, this indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

The Registrant plans to enter into a certain placement agency agreement, which provides that the placement agent is obligated, under some circumstances, to indemnify the Registrant’s directors, officers and controlling persons against specified liabilities, including liabilities under the Securities Act.

Item 15. Recent Sales of Unregistered Securities.

On February 15, 2024, the Registrant issued in a private placement with a single institutional investor (the “Purchaser”), warrants (the “February 2024 Warrants”) to purchase an aggregate of 2,221,880 shares of Common Stock (the “February 2024 Warrant Shares”) with an exercise price of $0.748. The February 2024 Warrants and the February 2024 Warrant Shares were offered pursuant to the exemption from registration provided in Section 4(a)(2) under the Securities Act and Rule 506(b) promulgated thereunder.

On December 6, 2023, the Registrant entered into a Securities Purchase Agreement (the “Purchase Agreement”) with the “Purchaser, pursuant to which the Registrant issued to the Purchaser, (i) in a registered direct offering, 331,000 shares of the Registrant’s Common Stock (the “Shares”), par value $0.001 per share (“Common Stock”), and pre-funded warrants to purchase 779,940 shares of Common Stock (the “Pre-Funded Warrants”) with an exercise price of $0.001 per share, and (ii) in a concurrent private placement, warrants (the “Common Warrants”) to purchase an aggregate of 2,221,880 shares of Common Stock (the “Common Warrant Shares”) with an exercise price of $1.23. The combined purchase price for one Share and two Common Warrants was $1.23, and the combined purchase price for one Pre-Funded Warrant and two Common Warrants was $1.229. The Common Warrants and the Common Warrant Shares were offered pursuant to the exemption from registration provided in Section 4(a)(2) under the Securities Act and Rule 506(b) promulgated thereunder.

In June 2022, the Registrant issued warrants to purchase 1,405,405 shares of Common Stock, with an exercise price of $4.625 per share (on a pre-2023 Reverse Stock Split basis). The warrants were issued in a private placement in connection with a registered direct offering of 678,745 shares of Common Stock and pre-funded warrants to purchase 726,660 shares of Common Stock with an exercise price of $0.001 per share (on a pre-2023 Reverse Stock Split basis). The combined purchase price for one share of Common Stock and one warrant was $4.625 and the combined purchase price for one pre-funded warrant and one warrant was $4.624 (on a pre-2023 Reverse Stock Split basis). The Registrant received aggregate gross proceeds in the offerings of approximately $6.5 million. The warrants and the shares of Common Stock issuable upon exercise of the warrants were offered pursuant to the exemption from registration provided in Section 4(a)(2) under the Securities Act and Rule 506(b) promulgated thereunder.

In June 2020, the Registrant issued warrants to purchase 432,000 shares of Common Stock, with an exercise price of $12.88 per share (on a pre-2023 Reverse Stock Split basis). The warrants were issued in a private placement in connection with a registered direct offering of 432,000 shares of Common Stock (on a pre-2023 Reverse Stock Split basis). The combined purchase price for one share of the Common Stock and one warrant was $16.00 (on a pre-2023 Reverse Stock Split basis). The Registrant received aggregate gross proceeds in the offerings of approximately $6.9 million. The warrants and the shares of Common Stock issuable upon exercise of the warrants were offered pursuant to the exemption from registration provided in Section 4(a)(2) under the Securities Act and Rule 506(b) promulgated thereunder.

Item 16. Exhibits and Financial Statement Schedules.

The exhibits to this registration statement are listed in the Exhibit Index to this registration statement, which immediately precedes the Signature Page and which Exhibit Index is hereby incorporated by reference.

Item 17. Undertakings.

The undersigned Registrant hereby undertakes:

To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:

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

(ii)    to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

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

provided, however, that paragraphs (i), (ii) and (iii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

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

That, for the purpose of determining liability under the Securities Act to any purchaser:

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

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

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

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