RISK FACTORS

Investing in our common stock is speculative and involves a high degree of risk. Before making an investment decision, you should carefully consider the risks described in the prospectus, this prospectus supplement and the documents incorporated by reference into the prospectus and this prospectus supplement, including the “Risk Factors” section of our Annual Report on Form 10-K for the year ended June 31, 2020, which is incorporated by reference into this prospectus supplement, as updated by annual, quarterly and other reports and documents we file with the SEC after the date of this prospectus supplement and that are incorporated by reference into this prospectus supplement. If any of these risks actually occurs, our business, financial condition or results of operations could be materially adversely affected. These risks and uncertainties are not the only ones faced by us. Additional risks and uncertainties, including those of which we are currently unaware or that are currently deemed immaterial, may also materially and adversely affect our business, financial condition, cash flows, prospects and the price of our common stock.

Risks Related to the Merger

Completion of the Merger is subject to a number of other conditions, and if these conditions are not satisfied or waived, the Merger will not be completed.

The obligations of Aytu and Neos to complete the Merger are subject to satisfaction or waiver of a number of conditions including, among other conditions: including Completion of the Merger is subject to customary closing conditions, including (1) the adoption of the Merger Agreement by a majority of the holders of the outstanding shares of Neos common stock, (2) approval of the issuance of Aytu common stock by a majority of the votes cast by Aytu stockholders on the matter, (3) that the conditions to the Debt Facility Letters (as defined below) have been satisfied as of the time of closing, and that the lenders do not dispute the satisfaction thereof, (4) accuracy of each party’s representations and warranties, subject to certain materiality standards set forth in the Merger Agreement, (5) the absence of a material adverse effect of either party and (6) compliance in all material respects with each party’s obligations under the Merger Agreement and certain other conditions.. For a more complete summary of the conditions that must be satisfied or waived prior to completion of the Merger refer to the Merger Agreement which is filed as Exhibit 2.1 to our Current Report on Form 8-K filed with the SEC on December 10, 2020. There can be no assurance that the conditions to closing the Merger will be satisfied or waived or that the Merger will be completed within the expected time frame, or at all.

The closing of this offering is not conditioned on the consummation of the Merger.

The closing of this offering is not conditioned on the consummation of the Merger. Therefore, upon the closing of this offering, you will become a holder of our common stock irrespective of whether the closing with respect to the Merger is consummated, delayed, restructured or terminated. If we do not complete the Merger, our common stock that you have purchased in this offering will not reflect any interest in the combined entity; if the closing is delayed, this interest will not be reflected during the period of delay; and if the Merger is restructured, it is uncertain as to whether this interest will be adversely affected. In addition, the price of our common stock may decline to the extent that the current market price of our common stock reflects a market assumption that the Merger will be completed and that we will realize certain anticipated benefits of acquiring Neos.

We will assume a significant amount of debt in the Merger, which, together with our other debt, could limit our operational flexibility or otherwise adversely affect our financial condition.

If the Merger closes, we will indirectly assume approximately $15.6 million of term debt currently owed by Neos, of which $0.6 will come due in April 2021, and $15.0 million which is due in May 2022 (assuming extension options are not exercised). If we fail to meet our obligations under the debt we assume in the Merger, the lenders would be entitled to foreclose on all or some of the collateral securing such debt which could have a material adverse effect on us and our ability to make expected distributions, and could threaten our continued viability.

We are subject to the risks normally associated with debt financing, including the following risks:

If any of the above risks occurred, our financial condition and results of operations could be materially adversely affected.

The market price of shares of Aytu common stock after the Merger will continue to fluctuate and may be affected by factors different from those that are currently affecting or historically have affected the market price of shares of Neos common stock or Aytu common stock.

Upon completion of the Merger, holders of shares of Neos common stock will become holders of shares of Aytu common stock. The market price of Aytu common stock may fluctuate significantly following completion of the Merger, and holders of shares of Neos common stock could lose the value of their investment in Aytu common stock if, among other things, the combined company is unable to achieve the expected growth in earnings, or if the operational cost savings estimates in connection with the integration of the Neos and Aytu business are not realized, or if the transaction costs relating to the Merger are greater than expected, or if the financing related to the Merger is on unfavorable terms. The market price also may decline if the combined company does not achieve the perceived benefits of the Merger as rapidly or to the extent anticipated by financial or industry analysts or if the effect of the Merger on the combined company’s financial position, results of operations or cash flows is not consistent with the expectations of financial or industry analysts. The issuance of shares of Aytu common stock in the Merger could on its own have the effect of depressing the market price for Aytu common stock. In addition, many Neos stockholders may decide not to hold the shares of Aytu common stock they receive as a result of the Merger. Other Neos stockholders, such as funds with limitations on their permitted holdings of stock in individual issuers, may be required to sell the shares of Aytu common stock they receive as a result of the Merger. Any such sales of Aytu common stock could have the effect of depressing the market price for Aytu common stock.

In addition, in the future Aytu may issue additional securities to raise capital. Aytu may also acquire interests in other companies by issuing Aytu common stock to finance the acquisition, in whole or in part. Aytu may also issue securities convertible into Aytu common stock.

Moreover, general fluctuations in stock markets could have a material adverse effect on the market for, or liquidity of, the Aytu common stock, regardless of Aytu’s actual operating performance.

The businesses of Aytu differ from those of Neos in important respects and, accordingly, the results of operations of the combined company after the Merger, as well as the market price of shares of Aytu common stock, may be affected by factors different from those that are currently affecting, historically have affected or would in the future affect the results of operations of Neos and Aytu as stand-alone public companies, as well as the market price of shares of Neos common stock and Aytu common stock prior to completion of the Merger.

Aytu and Neos may have difficulty attracting, motivating and retaining executives and other key employees in light of the Merger.

Aytu’s success after the transaction will depend in part on the ability of Aytu to retain key executives and other employees of Neos. Uncertainty about the effect of the Merger on Aytu and Neos employees may have an adverse effect on each of Aytu and Neos separately and consequently the combined business. This uncertainty may impair Aytu’s and/or Neos’ ability to attract, retain and motivate key personnel. Employee retention may be particularly challenging during the pendency of the Merger, as employees of Aytu and Neos may experience uncertainty about their future roles in the combined business.

Furthermore, if key employees of Aytu or Neos depart or are at risk of departing, including because of issues relating to the uncertainty and difficulty of integration, financial security or a desire not to become employees of the combined business, Aytu may have to incur significant costs in retaining such individuals or in identifying, hiring and retaining replacements for departing employees and may lose significant expertise and talent, and the combined company’s ability to realize the anticipated benefits of the Merger may be materially and adversely affected. No assurance can be given that the combined company will be able to attract or retain key employees to the same extent that Neos has been able to attract or retain employees in the past.

Aytu and Neos may be targets of transaction related lawsuits which could result in substantial costs and may delay or prevent the Merger from being completed. If the Merger is completed, Aytu will also assume Neos’ risks arising from various legal proceedings.

Securities class action lawsuits and derivative lawsuits are often brought against public companies that have entered into Merger agreements. Even if the lawsuits are without merit, defending against these claims can result in substantial costs and divert management time and resources. An adverse judgment could result in monetary damages, which could have a negative impact on Aytu’s and Neos’ respective liquidity and financial condition. Additionally, if a plaintiff is successful in obtaining an injunction prohibiting completion of the Merger, then that injunction may delay or prevent the Merger from being completed, which may adversely affect Aytu’s and Neos’ respective business, financial position and results of operation.

We have incurred, and will incur, substantial direct and indirect costs as a result of the Merger.

We have incurred and expects to incur additional material non-recurring expenses in connection with the Merger and completion of the transactions contemplated by the Merger Agreement. We have incurred significant legal, advisory and financial services fees in connection with the process of negotiating and evaluating the terms of the Merger. Additional significant unanticipated costs may be incurred in the course of coordinating the businesses of Neos and the Company after completion of the Merger.

Even if the Merger is not completed, we will need to pay certain costs relating to the Merger incurred prior to the date the Merger was abandoned, such as legal, accounting, financial advisory, filing and printing fees. Such costs may be significant and could have an adverse effect on the our plans. 

If the Merger is completed, Aytu may fail to realize the anticipated benefits and cost savings of the Merger, which could adversely affect the value of shares of Aytu common stock.

The success of the Merger will depend, in part, on Aytu’s ability to realize the anticipated benefits and cost savings from combining the businesses of Aytu and Neos. Aytu’s ability to realize these anticipated benefits and cost savings is subject to certain risks, including, among others:

If Aytu is not able to successfully combine the businesses of Aytu and Neos within the anticipated time frame, or at all, the anticipated cost savings and other benefits of the Merger may not be realized fully or may take longer to realize than expected, the combined businesses may not perform as expected and the value of the shares of Aytu common stock may be adversely affected.

Aytu and Neos have operated and, until completion of the Merger will continue to operate, independently, and there can be no assurances that their businesses can be integrated successfully. It is possible that the integration process could result in the loss of key Aytu or Neos employees, the disruption of either company’s or both companies’ ongoing businesses or in unexpected integration issues, higher than expected integration costs and an overall post-completion integration process that takes longer than originally anticipated. Specifically, issues that must be addressed in integrating the operations of Neos and Aytu in order to realize the anticipated benefits of the Merger so the combined business performs as expected include, among others:

In addition, at times, the attention of certain members of each company’s management and each company’s resources may be focused on completion of the Merger and the integration of the businesses of the two companies and diverted from day-to-day business

The Merger agreement contains provisions that make it more difficult for Aytu and Neos to pursue alternatives to the Merger and may discourage other companies from trying to acquire Neos for greater consideration than what Aytu has agreed to pay.

The Merger agreement contains provisions that make it more difficult for Neos to sell its business to a party other than Aytu, or for Aytu to sell its business. These provisions include a general prohibition on each party soliciting any acquisition proposal. Further, there are only limited exceptions to each party’s agreement that its board of directors will not withdraw or modify in a manner adverse to the other party the recommendation of its board of directors in favor of the adoption of the Merger agreement, in the case of Neos, or the approval of the stock issuance, in the case of Aytu, and the other party generally has a right to match any acquisition proposal that may be made. However, at any time prior to the adoption of the Merger agreement by Neos stockholders, in the case of Neos, or the approval of the stock issuance by Aytu stockholders, in the case of Aytu, such party’s board of directors is permitted to make an adverse recommendation change if it determines in good faith that the failure to take such action would be reasonably likely to be inconsistent with its fiduciary duties under applicable law. In the event that either the Neos Board or the Aytu Board make an adverse recommendation change, then such party may be required to pay a $2,000,000 termination fee. Aytu and Neos also will be required to pay certain transaction expenses and other costs incurred in connection with the Merger, whether or not the Merger is completed, including certain fees and expenses of the other party in connection with the Neos fee reimbursement or the Aytu fee reimbursement, as applicable.

The parties believe these provisions are reasonable and not preclusive of other offers, but these restrictions might discourage a third party that has an interest in acquiring all or a significant part of either Neos or Aytu from considering or proposing an acquisition proposal, even if that party were prepared to pay consideration with a higher per-share value than the currently proposed Merger consideration, in the case of Neos, or that party were prepared to enter into an agreement that may be favorable to Aytu or its stockholders, in the case of Aytu. Furthermore, the termination fees described above may result in a potential competing acquirer proposing to pay a lower per-share price to acquire the applicable party than it might otherwise have proposed to pay because of the added expense of the termination fee that may become payable by such party in certain circumstances.

The indebtedness of the combined company following completion of the Merger will be greater than Aytu’s indebtedness on a stand-alone basis and greater than the combined indebtedness of Aytu and Neos existing prior to the announcement of the Merger agreement. This increased level of indebtedness could adversely affect the combined company’s business flexibility, and increase its borrowing costs. Any resulting downgrades in Aytu’s and/or Neos’ credit ratings could adversely affect Aytu’s, Neos’ and/or the combined company’s respective businesses, cash flows, financial condition and operating results.

As of December 10, 2020, the current outstanding indebtedness of Neos is $41.0 million. As a result of the Merger, Aytu will assume the outstanding indebtedness of Neos at the closing. The amount of cash required to service Aytu’s increased indebtedness levels and thus the demands on Aytu’s cash resources will be greater than the amount of cash flows required to service the indebtedness of Aytu individually prior to the Merger. The increased levels of indebtedness could also reduce funds available to fund Aytu’s efforts to combine its business with Neos and realize expected benefits of the Merger and/or engage in investments in product development, capital expenditures, and other activities and may create competitive disadvantages for Aytu relative to other companies with lower debt levels. Aytu may be required to raise additional financing for working capital, capital expenditures, acquisitions or other general corporate purposes. Aytu’s ability to arrange additional financing or refinancing will depend on, among other factors, Aytu’s financial position and performance, as well as prevailing market conditions and other factors beyond Aytu’s control. Aytu cannot assure you that it will be able to obtain additional financing or refinancing on terms acceptable to Aytu or at all.

Aytu may not be able to service all of the combined company’s indebtedness and may be forced to take other actions to satisfy Aytu’s obligations under Aytu’s indebtedness, which may not be successful. Aytu’s failure to meet its debt service obligations could have a material adverse effect on the combined company’s business, financial condition and results of operations.

Aytu depends on cash on hand and revenue from operations to make scheduled debt payments. Aytu expects to be able to meet the estimated cash interest payments on the combined company’s debt following the Merger through a combination of the expected revenue from operations of the combined company. However, Aytu’s ability to generate sufficient revenue from operations of the combined company and to utilize other methods to make scheduled payments will depend on a range of economic, competitive and business factors, many of which are outside of Aytu’s control. There can be no assurance that these sources will be adequate. If Aytu is unable to service Aytu’s indebtedness and fund Aytu’s operations, Aytu will be forced to reduce or delay capital expenditures, seek additional capital, sell assets or refinance Aytu’s indebtedness. Any such action may not be successful and Aytu may be unable to service Aytu’s indebtedness and fund Aytu’s operations, which could have a material adverse effect on the combined company’s business, financial condition or results of operations.

Aytu will incur significant transaction and integration-related costs in connection with the Merger. In addition, the Merger may not be accretive, and may be dilutive, to Aytu’s earnings per share, which may negatively affect the market price of shares of Aytu’s common stock.

Aytu expects to incur a number of non-recurring costs associated with the Merger and combining the operations of the two companies. Aytu will incur significant transaction costs related to the Merger. Aytu also will incur significant integration-related fees and costs related to formulating and implementing integration plans, including facilities and systems consolidation costs and employment-related costs. Aytu continues to assess the magnitude of these costs, and additional unanticipated costs may be incurred in the Merger and the integration of the two companies’ businesses. While Aytu has assumed that a certain level of transaction expenses will be incurred, factors beyond Aytu’s control, such as certain of Neos’ expenses, could affect the total amount or the timing of these expenses. Although Aytu expects that the elimination of duplicative costs, as well as the realization of other efficiencies related to the integration of the businesses, should allow Aytu to offset integration-related costs over time, this net benefit may not be achieved in the near term, or at all.

Following the closing of the Merger, there is a risk that a significant amount of the combined company’s total assets will be related to acquired intangible assets and goodwill, which are subject to annual impairment reviews, or more frequent reviews if events or circumstances indicate that the carrying value may not be recoverable. Because of the significance of these assets, any charges for impairment as well as amortization of intangible assets could have a material adverse effect on the combined company’s results of operations and financial condition.

The combined company will be subject to the risks that Neos faces, in addition to the risks faced by Aytu. In particular, the success of the combined company will depend on its ability to obtain, commercialize and protect intellectual property.

Neos and Aytu currently have a limited number of products (including products to be acquired by Aytu from Cerecor in the Cerecor transaction), and the combined company may not be successful in marketing and commercializing these products. In addition, following the Merger Aytu may seek to develop current or new product candidates of both Aytu and Neos. The testing, manufacturing and marketing of these products would require regulatory approvals, including approval from the FDA and similar bodies in other countries. To the extent the combined company seeks to develop product candidates, the future growth of the combined company would be negatively affected if Aytu, Neos or the combined company fails to obtain requisite regulatory approvals within the expected time frames, or at all, in the United States and internationally for products in development and approvals for Aytu’s existing products for additional indications.

The unaudited pro forma combined financial information and prospective financial information incorporated by reference in this prospectus supplement are presented for illustrative purposes only and do not represent the actual financial position or results of operations of the combined company following completion of the Merger or reflect the effect of any divestitures that may be required in connection with the Merger.

The unaudited pro forma combined financial information and prospective financial information incorporated by reference in this prospectus supplement is presented for illustrative purposes only, contains a variety of adjustments, assumptions and preliminary estimates and does not represent the actual financial position or results of operations of Aytu and Neos prior to the Merger or that of the combined company following the Merger for several reasons. Among other things, the unaudited pro forma combined financial information does not reflect the effect of any potential divestitures that may occur prior to or subsequent to completion of the Merger, the projected realization of cost savings following completion of the Merger or any changes in applicable law (including applicable tax law). The actual financial positions and results of operations of Neos and Aytu prior to the Merger and that of the combined company following the Merger may not be consistent with, or evident from, the unaudited pro forma combined financial information or prospective financial information incorporated by reference in this prospectus supplement. In addition, the assumptions used in preparing the unaudited pro forma combined financial information and/or the prospective financial information incorporated by reference in this prospectus supplement may not be realized and may be affected by other factors, which could lead to material changes to the combined company’s business that are not reflected in the unaudited pro forma combined financial information.

Certain Neos agreements may contain change of control provisions that may have been triggered by the Merger that, if acted upon or not waived, could cause the combined company to lose the benefit of such agreement and incur liabilities or replacement costs, which could have a material adverse effect on the combined company.

Neos is party to, or may become party to after the date hereof, various agreements with third parties that may contain change of control provisions that may be triggered upon the completion of the Merger. Agreements with change of control provisions typically provide for or permit the termination of the agreement upon the occurrence of a change of control of one of the parties which can be waived by the relevant counterparties. In the event that there is such a contract or arrangement requiring a consent or waiver in relation to the Merger or the Merger agreement, for which such consent or waiver was not obtained, the combined company could lose the benefit of the underlying agreement and incur liabilities or replacement costs, which could have an adverse effect on the operations of the combined company.

The future results of the combined company may be adversely impacted if the combined company does not effectively manage its expanded operations following completion of the Merger.

Following completion of the Merger, the size of the combined company’s business will be significantly larger than the current size of either Aytu’s or Neos’ respective businesses. The combined company’s ability to successfully manage this expanded business will depend, in part, upon management’s ability to implement an effective integration of the two companies and its ability to manage a combined business with significantly larger size and scope with the associated increased costs and complexity. There can be no assurances that the management of the combined company will be successful or that the combined company will realize the expected operating efficiencies, cost savings and other benefits currently anticipated from the Merger.

Risks Related to This Offering

Future sales or other issuances of our common stock could depress the market for our common stock.

Sales of a substantial number of shares of our common stock, or the perception by the market that those sales could occur, could cause the market price of our common stock to decline or could make it more difficult for us to raise funds through the sale of equity in the future.

 If we make one or more significant acquisitions in which the consideration includes stock or other securities, our stockholders’ holdings may be significantly diluted. In addition, stockholders’ holdings may also be diluted if we enter into arrangements with third parties permitting us to issue shares of common stock in lieu of certain cash payments upon the achievement of milestones.

Our stock price can be volatile, which increases the risk of litigation, and may result in a significant decline in the value of your investment.

The trading price of our common stock has been and is likely to continue to be highly volatile and subject to wide fluctuations in price in response to various factors, many of which are beyond our control. These factors include:

In addition, equity markets in general, and the market for biotechnology and life sciences companies in particular, have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of companies traded in those markets. These broad market and industry factors may materially affect the market price of our common stock, regardless of our development and operating performance. In the past, following periods of volatility in the market price of a company’s securities, securities class-action litigation has often been instituted against that company. Such litigation, if instituted against us, could cause us to incur substantial costs to defend such claims and divert management’s attention and resources, which could seriously harm our business.

We have broad discretion to use the net proceeds from this offering and our investment of these proceeds pending any such use may not yield a favorable return.

We intend to use the net proceeds from this offering for working capital and general corporate purposes. However, our management will have broad discretion in the application of the net proceeds from this offering and could spend the proceeds in ways that do not improve our results of operations or enhance the value of our common stock. The failure by management to apply these funds effectively could result in financial losses that could have a material adverse effect on our business, cause the price of our common stock to decline and delay the development of our product candidates. Pending any such uses, we plan to invest the net proceeds of this offering in short-term and long-term, investment-grade, interest-bearing securities. These investments may not yield a favorable return to our stockholders.

You will experience immediate and substantial dilution.

Since the public offering price of the shares of common stock offered pursuant to this prospectus supplement and the accompanying prospectus is higher than the net tangible book value per share of our common stock, you will suffer substantial dilution in the net tangible book value of the common stock you purchase in this offering. See “Dilution” in this prospectus supplement for a more detailed discussion of the dilution you will incur if you purchase shares of our common stock in this offering.

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

In order to raise additional capital, we may in the future offer additional shares of our common stock or other securities convertible into or exchangeable for our common stock at prices that may not be the same as the price per share in this offering. We may sell shares or other securities in any other offering at a price per share that is less than the price per share paid by investors in this offering, and investors purchasing shares or other securities in the future could have rights superior to existing stockholders. The price per share at which we sell additional shares of our common stock, or securities convertible or exchangeable into common stock, in future transactions may be higher or lower than the price per share paid by investors 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.

USE OF PROCEEDS

We estimate that the net proceeds from the sale of the shares offered in this offering will be approximately $       , or approximately $        if the underwriters exercise in full their option to purchase additional shares of common stock, after deducting the underwriting discounts and commissions and estimated offering expenses payable by us.

We currently intend to use the net proceeds from this offering for working capital and general corporate purposes.

The precise amount and timing of the application of these net proceeds will depend upon a number of factors, such as the timing and progress of our research and development efforts and the timing and progress of any partnering or commercial efforts. As of the date of this prospectus supplement, we cannot specify with certainty all of the particular uses for the net proceeds from this offering. Depending on the outcome of our efforts and other unforeseen events, our plans and priorities may change and we may apply the net proceeds of this offering in different manners than we currently anticipate. Accordingly, our management will have broad discretion in the timing and application of these net proceeds.

DILUTION

If you invest in our common stock, your interest will be diluted immediately to the extent of the difference between the public offering price per share and the adjusted net tangible book value per share after this offering.

The net tangible book value of our common stock as of September 30, 2020, giving effect to the Reverse Split was approximately $65.9 million, or approximately $5.24 per share. Net tangible book value per share represents the amount of our total tangible assets, excluding goodwill and intangible assets, less total liabilities, divided by the total number of our common stock outstanding. Dilution per share to new investors represents the difference between the amount per share paid by new investors for each share in this offering and the net tangible book value per share immediately following the completion of this offering.

After giving effect to the           sale of shares of common stock in this offering at the offering price of $            per share, our as-adjusted net tangible book value as of September 30, 2020 would have been approximately $            million, or approximately $            per share. This represents an immediate increase in net tangible book value of approximately $           per share to our existing shareholders and an immediate dilution in as-adjusted net tangible book value of approximately $            per share to new investors of our common stock in this offering, as illustrated by the following table:

Notes

If the underwriters exercise in full their option to purchase            additional shares of our common stock, the as adjusted net tangible book value after this offering would be $            per share, representing an increase in net tangible book value of $            per share to existing stockholders and immediate dilution in net tangible book value of $            per share to purchasers in this offering.

To the extent that any options have been or are exercised, preferred shares are converted, new options are issued under our equity incentive plans or we otherwise issue additional common stock in the future, there will be further dilution to new investors. In addition, we may choose to raise additional capital due to market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans. 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 shareholders.

DESCRIPTION OF SECURITIES WE ARE OFFERING

Common Stock

The material terms and provisions of our common stock are described under the heading “Description of Capital Stock” in this prospectus supplement and the accompanying prospectus.

Underwriter Warrants

The following is a summary of the material terms and provisions of the underwriter warrants that are being offered hereby. This summary is subject to and qualified in its entirety by the form of warrant, which will be filed with the SEC as an exhibit to a Current Report on Form 8-K in connection with this offering and incorporated by reference into the registration statement of which this prospectus supplement forms a part.

Duration and Exercise Price

The underwriter warrants offered hereby will have an exercise price of $ per share. The underwriter warrants will be immediately exercisable and may be exercised until the fifth anniversary of the date of effectiveness of this offering. The exercise price and number of shares of common stock issuable upon exercise are subject to appropriate adjustment in the event of share dividends, share splits, reorganizations or similar events affecting our shares of common stock. Underwriter warrants will be issued in certificated form only.

Exercisability

The underwriter warrants will be exercisable, at the option of each holder, in whole or in part, by delivering to us a duly executed exercise notice accompanied by payment in full for the number of shares of common stock purchased upon such exercise (except in the case of a cashless exercise as discussed below). A holder (together with its affiliates) may not exercise any portion of such holder’s warrants to the extent that the holder would own more than 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding shares of common stock immediately after exercise, except that upon at least 61 days’ prior notice from the holder to us, the holder may increase the amount of ownership of outstanding shares of common stock after exercising the holder’s warrants up to 9.99% of the number of shares of common stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the underwriter warrants.

Cashless Exercise

If, at the time a holder exercises its underwriter warrants, a registration statement registering the issuance of the shares of common stock underlying the underwriter warrants under the Securities Act, is not then effective or available for the issuance of such shares, then in lieu of making the cash payment otherwise contemplated to be made to us upon such exercise in payment of the aggregate exercise price, the holder may elect instead to receive upon such exercise (either in whole or in part) the net number of shares of common stock determined according to a formula set forth in the underwriter warrant.

Fundamental Transactions

In the event of any fundamental transaction, as described in the underwriter warrants and generally including any merger with or into another entity, sale of all or substantially all of our assets, tender offer or exchange offer, or reclassification of our shares of common stock, then upon any subsequent exercise of a shares of common stock warrant, the holder will have the right to receive as alternative consideration, for each share of our shares of common stock that would have been issuable upon such exercise immediately prior to the occurrence of such fundamental transaction, the number of shares of common stock of the successor or acquiring corporation or of our company, if it is the surviving corporation, and any additional consideration receivable upon or as a result of such transaction by a holder of the number of shares of common stock for which the shares of common stock warrant is exercisable immediately prior to such event.

Transferability

In accordance with its terms and subject to applicable laws, a warrant may be transferred at the option of the holder upon surrender of the underwriter warrant to us together with the appropriate instruments of transfer and payment of funds sufficient to pay any transfer taxes (if applicable).

Fractional Shares

No fractional shares of common stock will be issued upon the exercise of the underwriter warrants. Rather, the number of shares of common stock to be issued will, at our election, either be rounded up to the nearest whole number or we will pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the exercise price.

Trading Market

There is no established trading market for any of the underwriter warrants, and we do not expect a market to develop. We do not intend to apply for a listing for any of the underwriter warrants on any securities exchange or other nationally recognized trading system. Without an active trading market, the liquidity of the underwriter warrants will be limited.

Rights as a Shareholder

Except as otherwise provided in the underwriter warrants or by virtue of the holders’ ownership of shares of common stock, the holders of underwriter warrants do not have the rights or privileges of holders of our shares of common stock, including any voting rights, until such warrant holders exercise their underwriter warrants.

UNDERWRITING

Pursuant to the underwriting agreement with H.C. Wainwright & Co., LLC, or the representative, as representative of the underwriters named below, we have agreed to issued and sell, and the underwriters have, severally and not jointly, agreed to purchase, the number of shares of common stock listed opposite their name below, less the underwriting discount, on the closing date, subject to the terms and conditions contained in the underwriting agreement. The underwriting agreement provides that the obligations of the underwriters are subject to certain customary conditions precedent, representations and warranties contained therein.

Pursuant to the underwriting agreement, the underwriters have agreed to purchase all of the shares sold under the underwriting agreement if any of these shares are purchased, other than those shares covered by the underwriters’ option to purchase additional shares of common stock described below. The underwriters have advised us that they do not intend to confirm sales to any account over which they exercise discretionary authority.

Discounts, Commissions and Expenses

The underwriters may offer the shares of common stock from time to time to purchasers directly or through agents, or through brokers in brokerage transactions on The Nasdaq Capital Market, or to dealers in negotiated transactions or in a combination of such methods of sale, or otherwise, at a fixed price or prices, which may be changed, or at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at negotiated prices, subject to receipt and acceptance by it and subject to its right to reject any order in whole or in part. The difference between the price at which the underwriters purchase shares from us and the price at which the underwriters resell such shares may be deemed underwriting compensation. If the underwriters effect such transactions by selling shares of common stock to or through dealers, such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriter and/or purchasers of shares of common stock for whom they may act as agents or to whom they may sell as principal.

The underwriters are offering the shares, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters and other conditions specified in the underwriting agreement. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

We have granted to the underwriters an option to purchase up to an additional                  shares of common stock (up to 15% of the shares of common stock in this offering) at the public offering price, less the underwriting discount. The option is exercisable for 30 days.

Any shares sold by the underwriters to securities dealers will be sold at the public offering price less a selling concession not in excess of $         per share.

The following table shows the public offering price, underwriting discount and proceeds, before expenses, to us. These amounts are shown assuming both no exercise and full exercise of the underwriters’ option to purchase additional shares.

We have also agreed to pay the representative a management fee equal to 1% of the aggregate gross proceeds in this offering. In addition, we have agreed to reimburse the expenses of the representative in the non-accountable sum of $40,000 in connection with this offering, reimburse the expenses of the underwriters, including its legal fees, up to $100,000 in connection with this offering, and $12,900 for the clearing expenses of the representative in connection with this offering. We estimate that the total expenses of the offering, excluding underwriting discounts and commissions and the management fee, will be approximately $[ ] and is payable by us.

Underwriter Warrants

We have agreed to issue underwriter warrants to purchase up to shares of common stock ( shares if the underwriters exercise their option to purchase additional shares in full) to the representative (or its designees), which represents 6.5% of the number of shares of common stock being sold in this offering, as part of the compensation payable to the underwriters in connection with this offering. The exercise price per share of the underwriter warrants is $ (equal to 125% of the public offering price per share for the shares of common stock sold in this offering) and the underwriter warrants have a term of five years from the date of effectiveness of this offering. The underwriter warrants will be exercisable immediately. This prospectus supplement also relates to the offering of the shares of common stock issuable upon exercise of the underwriter warrants.

Tail Financing Payments

In the event that any investors that participate in this offering provide any capital to us in a public or private offering or capital-raising transaction within 3 months following the expiration or termination of our engagement of the representative, we shall pay the representative a tail fee consisting of (a) 7.5% in cash fees and (b) 6.5% warrant coverage with respect to such capital.

Indemnification

We have agreed to indemnify the underwriters against certain liabilities, including civil liabilities under the Securities Act, or to contribute to payments that the underwriters may be required to make in respect of those liabilities.

Lock-Up Agreements

We have agreed to not sell any shares of our common stock or any securities convertible into or exercisable or exchangeable into share of common stock, subject to certain exceptions, for a period of 30 days after the date of this prospectus supplement unless we obtain a prior written consent of the representative. This consent may be given at any time without public notice, and the representative may consent in its sole discretion. The exceptions to the restriction include, among other things, issuance of any shares of our capital stock or securities convertible into shares of our capital stock that are issued as consideration in an acquisition, merger or similar strategic transaction approved by a majority of the disinterested directors, provided that such securities are issued as “restricted securities” as defined in Rule 144 and carry no registration rights that require or permit the filing of any registration statement in connection therewith within thirty (30) days after the date of this prospectus, and provided that any such issuance shall only be to a person providing us business synergies and additional benefits in addition to the investment of funds, but shall not include a transaction in which we are issuing securities primarily for the purpose of raising capital or to an entity whose primary business is investing in securities.

In addition, subject to certain limited circumstances, each of our directors and executive officers has entered into a lock-up agreement with the representative. Under the lock-up agreements, the directors and executive officers may not, directly or indirectly, sell, offer to sell, contract to sell, or grant any option for the sale (including any short sale), grant any security interest in, pledge, hypothecate, hedge, establish an open “put equivalent position” (within the meaning of Rule 16a-1(h) under the Exchange Act), or otherwise dispose of, or enter into any transaction which is designed to or could be expected to result in the disposition of, any shares of our common stock or securities convertible into or exchangeable for shares of our common stock, or publicly announce any intention to do any of the foregoing, unless such directors and executive officers obtain prior written consent of the representative for a period of 90 days from the date of this prospectus supplement. This consent may be given at any time without public notice, and the representative may consent in its sole discretion. Such lock-up restriction does not apply to any shares of common stock acquired in this offering by our directors and executive officers.

Price Stabilization, Short Positions and Penalty Bids

In connection with this offering, the underwriters may engage in stabilizing transactions, overallotment transactions, syndicate covering transactions and penalty bids in connection with our common stock.

Stabilizing transactions permit bids to purchase shares of common stock so long as the stabilizing bids do not exceed a specified maximum.

Overallotment transactions involve sales by the underwriter of shares of common stock in excess of the number of shares the underwriter is obligated to purchase. This creates a syndicate short position which may be either a covered short position or a naked short position. In a covered short position, the number of shares over-allotted by the underwriter is not greater than the number of shares that it may purchase in the overallotment option. In a naked short position, the number of shares involved is greater than the number of shares in the overallotment option. The underwriter may close out any short position by exercising its overallotment option and/or purchasing shares in the open market.

Syndicate covering transactions involve purchases of common stock in the open market after the distribution has been completed in order to cover syndicate short positions. Such a naked short position would be closed out by buying securities in the open market. A naked short position is more likely to be created if the underwriters are concerned that there could be downward pressure on the price of the securities in the open market after pricing that could adversely affect investors who purchase in the offering.

Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when the securities originally sold by the syndicate member are purchased in a stabilizing or syndicate covering transaction to cover syndicate short positions.

These stabilizing transactions, syndicate covering transactions and penalty bids may have the effect of raising or maintaining the market price of our common stock or preventing or retarding a decline in the market price of our common stock. As a result, the price of our common stock in the open market may be higher than it would otherwise be in the absence of these transactions. Neither we nor the underwriters make any representation or prediction as to the effect that the transactions described above may have on the price of our common stock. These transactions may be effected on The Nasdaq Capital Market, in the over-the-counter market or otherwise and, if commenced, may be discontinued at any time.

In connection with this offering, the underwriters also may engage in passive market making transactions in our common stock in accordance with Regulation M during a period before the commencement of offers or sales of shares of our common stock in this offering and extending through the completion of the distribution. In general, a passive market maker must display its bid at a price not in excess of the highest independent bid for that security. However, if all independent bids are lowered below the passive market maker’s bid that bid must then be lowered when specific purchase limits are exceeded. Passive market making may stabilize the market price of the securities at a level above that which might otherwise prevail in the open market and, if commenced, may be discontinued at any time.

Electronic Distribution

A prospectus in electronic format may be made available on the websites maintained by the underwriters, if any, participating in this offering and the underwriter may distribute prospectuses electronically. Other than the prospectus in electronic format, the information on these websites is not part of this prospectus or the registration statement of which this prospectus forms a part, has not been approved or endorsed by us or the underwriters, and should not be relied upon by investors.

Other Relationships

From time to time, certain of the underwriters and their affiliates have provided, and may provide in the future, various advisory, investment and commercial banking and other services to us in the ordinary course of business, for which they have received and may continue to receive customary fees and commissions. The representative served as our exclusive placement agent in connection with our registered direct offerings that we completed in March 2020, for which it received compensation. In addition, pursuant to a letter agreement with us (the “Letter Agreement”), effective as of July 1, 2020, the representative agreed to waive certain rights of first refusal. In exchange for such waiver, pursuant to the Letter Agreement, we paid to the representative on July 1, 2020 (A) an aggregate of $1,531,190, representing 8.5% of the cash proceeds received by us through such date from the exercise of certain warrants to purchase common stock issued by us on March 13, 2020 and March 23, 2020 (collectively, the “March Warrants”) and (B) placement agent warrants to purchase an aggregate of 923,000 shares of common stock, representing 6.5% of the shares of common stock issued pursuant to the exercise of the March Warrants through such date. In addition, we may in the future pay to the representative (i) a cash fee of 8.5% of the cash proceeds received by us from any exercise of the remaining March Warrants and (ii) warrants to purchase that number of shares of common stock equal to 6.5% of the shares of common stock issued pursuant to any exercises of the remaining March Warrants.

Risks Related to COVID-19

We are relying on FDA policies and guidance provisions that have changed very recently, and may continue to change, and relate directly to the COVID-19 health crisis. If we misinterpret this guidance or the guidance changes unexpectedly and/or materially, potential sales of the COVID-19 tests would be impacted.

The U.S. Food and Drug Administration (FDA) issued non-binding guidance for manufacturers relating to the pathway to enable FDA approval for devices related to testing for COVID-19 under an Emergency Use Authorization (EUA). Following the issuance of the initial published guidance, on March 16, 2020, revised guidance specific to COVID-19 “antibody tests” was issued. Newer guidance was published on May 4, 2020 further describing the requirements for serology tests to continue to be marketed under an Emergency Use Authorization. If our interpretation of the newly revised guidance is incorrect or specifics around the guidance change, the sales of the COVID-19 test could be materially impacted.

If our recently licensed COVID-19 IgG/IgM rapid tests do not perform as expected or the reliability of the technology is questioned, we could experience delayed or reduced market acceptance of the tests, increased costs and damage to our reputation.

Our success depends on the market’s confidence that we can provide reliable, high-quality COVID-19 diagnostic tests. We believe that customers in our target markets are likely to be particularly sensitive to product defects and errors. Our reputation and the public image of our licensed COVID-19 diagnostic tests may be impaired if they fail to perform as expected or are perceived as difficult to use. Despite quality control testing, defects or errors could occur with the tests.

In the future, if our licensed COVID-19 diagnostic tests experience a material defect or error, this could result in loss or delay of revenues, delayed market acceptance, damaged reputation, diversion of development resources, legal claims, increased insurance costs or increased service and warranty costs, any of which could harm our business. Such defects or errors could also prompt us to amend certain warning labels or narrow the scope of the use of our diagnostic tests, either of which could hinder our success in the market. Even after any underlying concerns or problems are resolved, any widespread concerns regarding our technology or any manufacturing defects or performance errors in the test could result in lost revenue, delayed market acceptance, damaged reputation, increased service and warranty costs and claims against us.

If we become subject to claims relating to improper handling, storage or disposal of hazardous materials, we could incur significant cost and time to comply.

Our research and development processes involve the controlled storage, use and disposal of hazardous materials, including biological hazardous materials. We are subject to foreign, federal, state and local regulations governing the use, manufacture, storage, handling and disposal of materials and waste products. We may incur significant costs complying with both existing and future environmental laws and regulations. In particular, we are subject to regulation by the Occupational Safety and Health Administration, (OSHA), and the Environmental Protection Agency (EPA), and to regulation under the Toxic Substances Control Act and the Resource Conservation and Recovery Act in the United States. OSHA or the EPA may adopt additional regulations in the future that may affect our research and development programs. The risk of accidental contamination or injury from hazardous materials cannot be eliminated completely. In the event of an accident, we could be held liable for any damages that result, and any liability could exceed the limits or fall outside the coverage of our workers’ compensation insurance. We may not be able to maintain insurance on acceptable terms, if at all.

Our licensed COVID-19 tests have not been manufactured on a high-volume scale and could be subject to unforeseen scale-up risks.

While the manufacturers of the COVID-19 IgG/IgM rapid rests have experience manufacturing diagnostic tests, there can be no assurance that they can manufacture the COVID-19 diagnostic tests at a scale that is adequate for our current and future commercial needs. We may face significant or unforeseen difficulties in securing adequate supply of the COVID-19 diagnostic tests, relating to the manufacturing of the tests. These risks include but are not limited to:

These and other difficulties may only become apparent when scaling up to the manufacturing process of the COVID-19 diagnostic tests to a more substantive commercial scale. In the event the tests cannot be manufactured in sufficient commercial quantities or manufacturing is delayed, our future prospects could be significantly impacted and our financial prospects could be materially harmed.

Our suppliers may experience development or manufacturing problems or delays that could limit the growth of our revenue or increase our losses.

We may encounter unforeseen situations in the manufacturing of the COVID-19 diagnostic tests that could result in delays or shortfalls in our production. Suppliers may also face similar delays or shortfalls. In addition, suppliers’ production processes may have to change to accommodate any significant future expansion of manufacturing capacity, which may increase suppliers’ manufacturing costs, delay production of diagnostic tests, reduce our product gross margin and adversely impact our business. If we are unable to keep up with demand for the COVID-19 diagnostic test by successfully securing supply and shipping our diagnostic tests in a timely manner, our revenue could be impaired, market acceptance for the test could be adversely affected and our customers might instead purchase our competitors’ diagnostic tests.

We have relied and expect to continue to rely on third parties to conduct studies of the COVID-19 diagnostic tests that will be required by the FDA or other regulatory authorities and those third parties may not perform satisfactorily.

Although we intend to sell the COVID-19 IgG/IgM rapid tests by virtue of recent FDA guidance allowing for reduced product clinical and analytical studies, we have relied on third parties, such as independent testing laboratories and hospitals, to conduct such studies. Our reliance on these third parties will reduce our control over these activities. These third-party contractors may not complete activities on schedule or conduct studies in accordance with regulatory requirements or our study design. We cannot control whether they devote sufficient time, skill and resources to our studies. Our reliance on third parties that we do not control will not relieve us of any applicable requirement to prepare, and ensure compliance with, various procedures required under good clinical practices. If these third parties do not successfully carry out their contractual duties or regulatory obligations or meet expected deadlines, if the third parties need to be replaced or if the quality or accuracy of the data they obtain is compromised due to their failure to adhere to our clinical protocols or regulatory requirements or for other reasons, our studies may be extended, delayed, suspended or terminated, and we may not be able to obtain regulatory approval for additional diagnostic tests.

If the manufacturers’ delivery of the COVID-19 tests and the required clinical data is delayed, then our ability to obtain necessary regulatory approvals and/or authorizations to distribute the COVID-19 tests will be impaired, which will adversely affect our business plans.

While the FDA has provided a path forward to begin selling the COVID-19 tests on an expedited basis, we are still required to provide the FDA with data concerning the validation of the tests and to satisfy certain labeling conditions. If the manufacturers are delayed in delivering to us the COVID-19 tests and related validation data, we will, in turn, be delayed in obtaining FDA authorization or approval required before we can begin selling the COVID-19 tests. Any such delays will adversely affect our business plans.

We rely on third parties to manufacture the COVID-19 tests for us and if such third party refuses or is unable to supply us with the COVID-19 test, our business will be materially harmed.

We rely on third parties to manufacture the COVID-19 diagnostic tests, which manufacturers licenses their rights from the owners of the intellectual property underlying the COVID-19 tests. If any issues arise with respect to the manufacturers’ ability to manufacture and deliver to us the COVID-19 tests, our business could be materially harmed.

While we have obtained an exclusive distribution agreement for the right to commercialize one of the COVID-19 test in the United States, Canada and Mexico, the manufacturer has no obligation to supply us with a minimum amount of, or any, COVID-19 tests. The manufacturer may choose not to supply us with a sufficient quantity of such tests in order to supply such tests to other distributors, or for any reason. In addition, the manufacturer may be unable to provide us with an adequate supply of COVID-19 tests for various reasons, including, among others, if it becomes insolvent, if a United States regulatory authority or other governments block the import or sale of the COVID-19 tests, if it fails to maintain its rights to manufacture the COVID-19 test, or if the owner of the underlying intellectual property fails to adequately maintain such intellectual property.

If there is little or no demand for the COVID-19 tests our business could be materially harmed.

While we have received a number of inquiries regarding the COVID-19 tests and expect to receive orders upon our receipt of a supply of COVID-19 tests, there is no guarantee that such inquiries will result in customer orders. If no orders for COVID-19 tests are made, our business will be materially harmed.

Our business may be adversely affected by the effects of the COVID-19 pandemic.

In December 2019, a novel strain of coronavirus, SARS-CoV-2, causing a disease referred to as COVID-19, was reported to have surfaced in Wuhan, China. It has since spread to multiple other countries; and, in March 2020, the World Health Organization declared the COVID-19 outbreak a pandemic. This pandemic has adversely affected or has the potential to adversely affect, among other things, the economic and financial markets and labor resources of the countries in which we operate, our manufacturing and supply chain operations, research and development efforts, commercial operations and sales force, administrative personnel, third-party service providers, business partners and customers, and the demand for some of our marketed products.

The COVID-19 pandemic has resulted in travel and other restrictions to reduce the spread of the disease, including governmental orders across the globe, which, among other things, direct individuals to shelter at their places of residence, direct businesses and governmental agencies to cease non-essential operations at physical locations, prohibit certain non-essential gatherings, maintain social distancing, and order cessation of non-essential travel. As a result of these recent developments, we have implemented work-from-home policies for a significant part of our employees. The effects of shelter-in-place and social distancing orders, government-imposed quarantines, and work-from-home policies may negatively impact productivity, disrupt our business, and delay our business timelines, the magnitude of which will depend, in part, on the length and severity of the restrictions and other limitations on our ability to conduct our business in the ordinary course. Such restrictions and limitations may also negatively impact our access to regulatory authorities (which may be affected, among other things, by travel restrictions and may be delayed in responding to inquiries, reviewing filings, and conducting inspections). The COVID-19 pandemic may also result in the loss of some of our key personnel, either temporarily or permanently. In addition, our sales and marketing efforts may be impacted by postponement of face-to-face meetings and restrictions on access by non-essential personnel to hospitals or clinics, all of which could slow adoption and implementation of our marketed products, resulting in lower net product sales. For example, while the impact of shelter-in-place and social distancing orders, physicians’ office closures, and delays in the treatment of patients following the COVID-19 pandemic on our net product sales of our products for the three months ended March 31, 2020 was limited, overall demand was lower in April 2020 compared to the same period of 2019. In addition to other potential impacts of the COVID-19 pandemic on net product sales, we expect to see continued adverse impact on new patient starts for all products while these measures remain in place. See Part I, Item 2. “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Results of Operations” for a discussion of our net product sales. Demand for some or all of our marketed products may continue to be reduced while the shelter-in-place or social distancing orders are in effect and, as a result, some of our inventory may become obsolete and may need to be written off, impacting our operating results. These and similar, and perhaps more severe, disruptions in our operations may materially adversely impact our business, operating results, and financial condition.

Quarantines, shelter-in-place, social distancing, and similar government orders (or the perception that such orders, shutdowns, or other restrictions on the conduct of business operations could occur) related to COVID-19 or other infectious diseases are impacting personnel at our research and manufacturing facilities, our suppliers, and other third parties on which we rely, and may impact the availability or cost of materials produced by or purchased from such parties, which could result in a disruption in our supply chain.

In addition, infections and deaths related to COVID-19 may disrupt the United States’ healthcare and healthcare regulatory systems. Such disruptions could divert healthcare resources away from, or materially delay, FDA review and potential approval of our marketed products. It is unknown how long these disruptions could continue. Further, while we are focused on therapies to address the COVID-19 pandemic, our other product candidates may need to be de-prioritized. Any elongation or de-prioritization of our other products could materially affect our business.

While the potential economic impact brought by, and the duration of, the COVID-19 pandemic may be difficult to assess or predict, it is currently resulting in significant disruption of global financial markets. This disruption, if sustained or recurrent, could make it more difficult for us to access capital if needed. In addition, a recession or market correction resulting from the spread of COVID-19 could materially affect our business and the value of our common stock. The global COVID-19 pandemic continues to rapidly evolve. The ultimate impact of this pandemic is highly uncertain and subject to change. We do not yet know the full extent of potential delays or impacts on our business, healthcare systems, or the global economy as a whole. These effects could have a material impact on our operations. To the extent the COVID-19 pandemic adversely affects our business, prospects, operating results, or financial condition, it may also materially affect our business.

Risks Related to the Healight Technology

We must rely on a third party to develop and commercialize the Healight Technology.

We must rely on Cedars-Sinai Medical Center to conduct testing and clinical trials of the Healight Technology (“Healight”). As a result, we are expected to remain dependent on a third party to conduct ongoing trials and the timing and completion of these trials will be partially controlled by such third party and may result in delays to the Healight development program. Nevertheless, we are responsible for ensuring that each of the trials is conducted in accordance with the applicable protocol and legal, regulatory, and scientific standards and our reliance on a third party does not relieve us of our regulatory responsibilities. If we or Cedars-Sinai Medical Center fail to comply with applicable requirements, the FDA may require to perform additional clinical tests.

There is no guarantee that Cedars-Sinai Medical Center will devote adequate time and resources to the Healight development activities or perform as contractually required. Furthermore, Cedars-Sinai Medical Center may also have relationships with other entities, some of which may be our competitors. If Cedars-Sinai Medical Center fails to meet expected deadlines, adhere to our clinical protocols, meet regulatory requirements, or otherwise performs in a substandard manner, or terminates its engagement with us, the timelines for the Healight technology development may be extend, delayed, suspended, or terminated.

The development of Healight faces uncertainties related to testing.

The development of Healight is based on scientific hypotheses and experimental approaches that may not lead to desired results. It is possible that the timeframe for obtaining proof of principle and other results may be considerably longer than originally anticipated, or may not be possible given time, resource, financial, strategic, and collaborator constraints. Success in one stage of testing is not necessarily an indication that the Healight program will succeed in later stages of testing and development. The discovery of unexpected side effects, inability to increase scale of manufacture, market attractiveness, regulatory hurdles, competition, as well as other factors may make the Healight technology unattractive of unsuitable for human use.

Risks Related to our Bylaws

Our Amended and Restated Bylaws provides that the Court of Chancery of the State of Delaware is the exclusive forum for certain litigation that may be initiated by our stockholders, including claims under the Securities Act, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or employees.

Our Amended and Restated Bylaws provides that the Court of Chancery of the State of Delaware shall, to the fullest extent permitted by law, be the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim for breach of a fiduciary duty owed by any of our directors, officers, employees or agents to us or our stockholders, (iii) any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law, our certificate of incorporation or our bylaws or (iv) any action asserting a claim governed by the internal affairs doctrine. The choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers, employees or agents, which may discourage such lawsuits against us and our directors, officers, employees and agents. Stockholders who do bring a claim in the Court of Chancery could face additional litigation costs in pursuing any such claim, particularly if they do not reside in or near the State of Delaware. The Court of Chancery may also reach different judgments or results than would other courts, including courts where a stockholder considering an action may be located or would otherwise choose to bring the action, and such judgments or results may be more favorable to us than to our stockholders. Alternatively, if a court were to find the choice of forum provision contained in our certificate of incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could adversely affect our business and financial condition. Notwithstanding the foregoing, the exclusive provision shall not preclude or contract the scope of exclusive federal or concurrent jurisdiction for actions brought under the Exchange Act, or the Securities Act of 1933, as amended, or the Securities Act, or the respective rules and regulations promulgated thereunder.

USE OF PROCEEDS

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

DESCRIPTION OF DEBT SECURITIES

This section describes the general terms and provisions of the debt securities that we may offer using this prospectus and the related indenture. This section is only a summary and does not purport to be complete. You must look to the relevant form of debt security and the related indenture for a full understanding of all terms of any series of debt securities. The form of debt security and the related indenture have been or will be filed or incorporated by reference as exhibits to the registration statement of which this prospectus is a part. See “Where You Can Find More Information” for information on how to obtain copies.

We may issue debt securities from time to time, in one or more series, as either senior or subordinated debt or as senior or subordinated convertible debt. While the terms we have summarized below will apply generally to any debt securities that we may offer under this prospectus, we will describe the particular terms of any debt securities that we may offer in more detail in the applicable prospectus supplement. The terms of any debt securities offered under a prospectus supplement may differ from the terms described below. Unless otherwise mentioned or unless the context requires otherwise, whenever we refer to the indenture, we also are referring to any supplemental indentures that specify the terms of a particular series of debt securities.

We will issue the debt securities under the indenture that we will enter into with the trustee named in the indenture. The indenture will be qualified under the Trust Indenture Act of 1939, as amended, or the Trust Indenture Act. We have filed the form of indenture as an exhibit to the registration statement of which this prospectus is a part, and supplemental indentures and forms of debt securities containing the terms of the debt securities being offered will be filed as exhibits to the registration statement of which this prospectus is a part or will be incorporated by reference from reports that we file with the SEC.

The following summary of material provisions of the debt securities and the indenture is subject to, and qualified in its entirety by reference to, all of the provisions of the indenture applicable to a particular series of debt securities. We urge you to read the applicable prospectus supplements and any related free writing prospectuses related to the debt securities that we may offer under this prospectus, as well as the complete indenture that contains the terms of the debt securities.

General

The indenture does not limit the amount of debt securities that we may issue. It provides that we may issue debt securities up to the principal amount that we may authorize and may be in any currency or currency unit that we may designate. Except for the limitations on consolidation, merger and sale of all or substantially all of our assets contained in the indenture, the terms of the indenture do not contain any covenants or other provisions designed to give holders of any debt securities protection against changes in our operations, financial condition or transactions involving us.

We may issue the debt securities issued under the indenture as “discount securities,” which means they may be sold at a discount below their stated principal amount. These debt securities, as well as other debt securities that are not issued at a discount, may be issued with “original issue discount,” or OID, for U.S. federal income tax purposes because of interest payment and other characteristics or terms of the debt securities. Material U.S. federal income tax considerations applicable to debt securities issued with OID will be described in more detail in the applicable prospectus supplement.

We will describe in the applicable prospectus supplement the terms of the series of debt securities being offered, including:

Conversion or Exchange Rights

We will set forth in the applicable prospectus supplement the terms on which a series of debt securities may be convertible into or exchangeable for our common stock or our other securities. We will include provisions as to settlement upon conversion or exchange and whether conversion or exchange is mandatory, at the option of the holder or at our option. We may include provisions pursuant to which the number of shares of our common stock or our other securities that the holders of the series of debt securities receive would be subject to adjustment.

Consolidation, Merger or Sale

Unless we provide otherwise in the prospectus supplement applicable to a particular series of debt securities, the indenture will not contain any covenant that restricts our ability to merge or consolidate, or sell, convey, transfer or otherwise dispose of our assets as an entirety or substantially as an entirety. However, any successor to or acquirer of such assets (other than a subsidiary of ours) must assume all of our obligations under the indenture or the debt securities, as appropriate.

Events of Default under the Indenture

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

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

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

Subject to the terms of the indenture, if an event of default under an indenture shall occur and be continuing, the trustee will be under no obligation to exercise any of its rights or powers under such indenture at the request or direction of any of the holders of the applicable series of debt securities, unless such holders have offered the trustee reasonable indemnity. The holders of a majority in principal amount of the outstanding debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee, or exercising any trust or power conferred on the trustee, with respect to the debt securities of that series, provided that:

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

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

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

Modification of Indenture; Waiver

Unless we provide otherwise in the prospectus supplement applicable to a particular series of debt securities, we and the trustee may change an indenture without the consent of any holders with respect to specific matters:

In addition, under the indenture, the rights of holders of a series of debt securities may be changed by us and the trustee with the written consent of the holders of at least a majority in aggregate principal amount of the outstanding debt securities of each series that is affected. However, unless we provide otherwise in the prospectus supplement applicable to a particular series of debt securities, we and the trustee may make the following changes only with the consent of each holder of any outstanding debt securities affected:

Discharge

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

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

We will issue the debt securities of each series only in fully registered form without coupons and, unless we provide otherwise in the applicable prospectus supplement, in denominations of $1,000 and any integral multiple thereof. The indenture provides that we may issue debt securities of a series in temporary or permanent global form and as book-entry securities that will be deposited with, or on behalf of, The Depository Trust Company, or DTC, or another depositary named by us and identified in the applicable prospectus supplement with respect to that series. To the extent the debt securities of a series are issued in global form and as book-entry, a description of terms relating to any book-entry securities will be set forth in the applicable prospectus supplement.

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

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

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

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

Information Concerning the Trustee

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

Payment and Paying Agents

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

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

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

Governing Law

The indenture and the debt securities, and any claim, controversy or dispute arising under or related to the indenture or the debt securities, will be governed by and construed in accordance with the laws of the State of New York, except to the extent that the Trust Indenture Act is applicable.

DESCRIPTION OF CAPITAL STOCK

General

This prospectus describes the general terms of our capital stock. For a more detailed description of our capital stock, you should read the applicable provisions of the Delaware General Corporation Law, or DGCL, and our charter and bylaws.

Our certificate of incorporation provides that we may issue up to 200,000,000 shares of common stock, par value $0.0001 per share, and up to 50,000,000 shares of preferred stock, par value $0.0001 per share, and permits our board of directors, without stockholder approval, to amend the charter to increase or decrease the aggregate number of shares of stock or the number of shares of stock of any class or series that we have authority to issue. As of June 1, 2020, there were 120,614,876 shares of our common stock outstanding and no shares of our preferred stock outstanding. Under Delaware law, stockholders generally are not personally liable for our debts or obligations solely as a result of their status as stockholders.

Common Stock

Holders of our common stock generally have no preference, conversion, exchange, sinking fund, redemption or appraisal rights and have no preemptive rights to subscribe for any of our securities. Holders of our common stock are entitled to receive dividends when authorized by our board of directors out of assets legally available for the payment of dividends. They are also entitled to share ratably in our assets legally available for distribution to our stockholders in the event of our liquidation, dissolution or winding up, after payment of or adequate provision for all of our known debts and liabilities. These rights are subject to the preferential rights of any other class or series of our stock. The outstanding shares of common stock are, and any shares offered by this prospectus will be when issued and paid for, fully paid and nonassessable.

Each outstanding share of common stock entitles the holder to one vote on all matters submitted to a vote of stockholders, including the election of directors. Except as provided with respect to any other class or series of stock, the holders of our common stock will possess the exclusive voting power. In uncontested elections, directors are elected by a majority of all of the votes cast in the election of directors, and in contested elections, directors are elected by a plurality of all of the votes cast in the election of directors.

Preferred Stock

Our board of directors has the authority, without stockholder approval, to issue, at any time and from time to time, up to 50,000,000 shares of our preferred stock in one or more classes or series. Each such class or series shall have such preferences, conversion or other rights, voting powers, restrictions, limitations as to dividends or other distributions, qualifications and terms or conditions of redemption as shall be determined by our board of directors and set forth in articles supplementary relating to such class or series. The rights of the holders of our common stock will be subject to, and may be adversely affected by, the rights of holders of any preferred stock that may be issued in the future. Such rights may include voting and conversion rights which could adversely affect the holders of the common stock. Satisfaction of any dividend or liquidation preferences of outstanding preferred stock would reduce the amount of funds available, if any, for the payment of dividends or liquidation amounts on common stock.

A prospectus supplement, relating to any offered class or series of preferred stock, will specify the following terms of such class or series, as applicable:

Transfer Agent and Registrar

The transfer agent of our common stock is Issuer Direct Corporation. Their address is 500 Perimeter Park Drive, Suite D, Morrisville, NC 27560.

DESCRIPTION OF OTHER SECURITIES

Warrants

We may issue warrants to purchase the securities described in this prospectus. Unless otherwise provided in the applicable prospectus supplement, each series of warrants will be issued under a separate warrant agreement to be entered into between us and a warrant agent. Additional information regarding any warrants we may offer and the related warrant agreement will be set forth in the applicable prospectus supplement. As of June 1, 2020, the following warrants were outstanding:

Each of these warrants entitles the holder to purchase one share of common stock at prices ranging between $1.25 and $3,120, as converted, per share, with a weighted average exercise price of $3.78 per share. Certain of these warrants has a net exercise provision under which its holder may, in lieu of payment of the exercise price in cash, surrender the warrant and receive a net amount of shares based on the fair market value of our common stock at the time of exercise of the warrant after deduction of the aggregate exercise price. Each of these warrants also contains provisions for the adjustment of the exercise price and the aggregate number of shares issuable upon the exercise of the warrant in the event of dividends, share splits, reorganizations and reclassifications and consolidations. Certain of these warrants contain a provision requiring a reduction to the exercise price in the event we issue common stock, or securities convertible into or exercisable for common stock, at a price per share lower than the warrant exercise price.

Rights

We may issue rights to purchase our common stock, preferred stock, or warrants in one or more series. Rights may be issued independently or together with any other offered security and may or may not be transferable by the person purchasing or receiving the subscription rights. In connection with any rights offering to our stockholders, we may enter into a standby underwriting arrangement with one or more underwriters pursuant to which the underwriters will purchase any of the offered securities remaining unsubscribed after the expiration of the rights offering. In connection with a rights offering to our shareholders, we will distribute certificates evidencing the rights and an applicable prospectus supplement to our shareholders on the record date that we set for receiving rights in the rights offering.

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

Units

We may issue units comprised of one or more of the securities described in this prospectus in any combination. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security. The unit agreement, if any, under which a unit is issued may provide that the securities comprising the unit may not be held or transferred separately, at any time or at any time before a specified date.

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

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

PLAN OF DISTRIBUTION

We may sell the securities from time to time pursuant to underwritten public offerings, direct sales to the public, negotiated transactions, block trades or a combination of these methods. We may sell the securities to or through underwriters or dealers, through agents, directly to one or more purchasers, or through any combination of these methods. The distribution of the securities may be effected from time to time in one or more transactions at a fixed price or prices, which may be changed, at market prices prevailing at the time of sale, at prices related to the prevailing market prices or at negotiated prices.

We may issue securities to other companies or their security holders to acquire those companies or equity interests in those companies, or to acquire assets of those companies, through mergers or consolidations with us or any of our subsidiaries, or through the exchange of our securities for securities of the other companies, or through the exchange of assets of other companies for our securities, or through similar transactions. We may also issue securities to third parties to acquire patents or other intellectual property or licenses or similar rights to use patents or other intellectual property.

A prospectus supplement or supplements (and any related free writing prospectus that we may authorize to be provided to you) will describe the terms of the offering of the securities, including, to the extent applicable:

Only underwriters named in the prospectus supplement are underwriters of the securities offered by the prospectus supplement.

By Underwriters

If underwriters are used in the sale, they will acquire the securities for their own account and may resell the securities from time to time in one or more transactions at a fixed public offering price or at varying prices determined at the time of sale. The obligations of the underwriters to purchase the securities will be subject to the conditions set forth in the applicable underwriting agreement. We may offer the securities to the public through underwriting syndicates represented by managing underwriters or by underwriters without a syndicate. Subject to certain conditions, the underwriters will be obligated to purchase all of the securities offered by the prospectus supplement. Any public offering price and any discounts or concessions allowed or reallowed may change from time to time. We may use underwriters with whom we have a material relationship. We will describe in the prospectus supplement, naming the underwriter, the nature of any such relationship.

By Dealers

If a dealer is utilized in the sale of any securities offered by this prospectus, we will sell those securities to the dealer, as principal. The dealer may then resell the securities to the public at varying prices to be determined by the dealer at the time of resale. We will set forth the names of the dealers and the terms of the transaction in the applicable prospectus supplement.

By Agents

We may sell securities directly or through agents we designate from time to time. We will name any agent involved in the offering and sale of securities and we will describe any commissions we will pay the agent in the prospectus supplement. Unless the prospectus supplement states otherwise, our agent will act on a best-efforts basis for the period of its appointment.

By Direct Sales

We may also directly sell securities offered by this prospectus. In this case, no underwriters or agents would be involved. We will describe the terms of those sales in the applicable prospectus supplement.

Electronic Auctions

We also may make sales through the Internet or through other electronic means. Since we may from time to time elect to offer securities directly to the public, with or without the involvement of agents, underwriters or dealers, utilizing the Internet or other forms of electronic bidding or ordering systems for the pricing and allocation of the securities, you will want to pay particular attention to the description of that system we will provide in an applicable prospectus supplement.

The electronic system may allow bidders to directly participate, through electronic access to an auction site, by submitting conditional offers to buy that are subject to acceptance by us, and which may directly affect the price or other terms and conditions at which the securities are sold. These bidding or ordering systems may present to each bidder, on a so-called “real-time” basis, relevant information to assist in making a bid, such as the clearing spread at which the offering would be sold, based on the bids submitted, and whether a bidder’s individual bids would be accepted, prorated or rejected. Of course, many pricing methods can and may also be used.

Upon completion of the electronic auction process, securities will be allocated based on prices bid, terms of bid or other factors. The final offering price at which securities would be sold and the allocation of securities among bidders would be based in whole or in part on the results of the Internet or other electronic bidding process or auction.

General Information

Underwriters, dealers and agents that participate in the distribution of the securities offered by this prospectus may be deemed underwriters under the Securities Act, and any discounts or commissions they receive from us and any profit on their resale of the securities may be treated as underwriting discounts and commissions under the Securities Act.

We may authorize agents, dealers or underwriters to solicit offers by certain types of institutional investors to purchase securities from us at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. We will describe the conditions to these contracts and the commissions we must pay for solicitation of these contracts in the prospectus supplement.

We may provide agents and underwriters with indemnification against civil liabilities related to this offering, including liabilities under the Securities Act, or contribution with respect to payments that the agents or underwriters may make with respect to these liabilities. Agents and underwriters may engage in transactions with, or perform services for, us in the ordinary course of business.

Some or all of the securities we offer, other than shares of common stock, will be new issues of securities with no established trading market. Any underwriters may make a market in these securities, but will not be obligated to do so and may discontinue any market making at any time without notice. We cannot guarantee the liquidity of the trading markets for any securities.

We may engage in at-the-market offerings into an existing trading market in accordance with Rule 415(a)(4) under the Securities Act. We may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third parties may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of shares, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of shares. The third parties in such sale transactions will be identified in the applicable prospectus supplement.

One or more firms, referred to as “remarketing firms,” may also offer or sell the securities, if the prospectus supplement so indicates, in connection with a remarketing arrangement upon their purchase. Remarketing firms will act as principals for their own accounts or as agents for us. These remarketing firms will offer or sell the securities in accordance with the terms of the securities. The prospectus supplement will identify any remarketing firm and the terms of its agreement, if any, with us and will describe the remarketing firm’s compensation. Remarketing firms may be deemed to be underwriters in connection with the securities they remarket.

Any underwriter may engage in overallotment, stabilizing transactions, short covering transactions and penalty bids in accordance with Regulation M under the Exchange Act. Overallotment involves sales in excess of the offering size, which create a short position. This short sales position may involve either “covered” short sales or “naked” short sales. Covered short sales are short sales made in an amount not greater than the underwriters’ over-allotment option to purchase additional securities in this offering described above. The underwriters may close out any covered short position either by exercising their over-allotment option or by purchasing securities in the open market. To determine how they will close the covered short position, the underwriters will consider, among other things, the price of securities available for purchase in the open market, as compared to the price at which they may purchase securities through the over-allotment option. Naked short sales are short sales in excess of the over-allotment option. The underwriters must close out any naked short position by purchasing securities in the open market. A naked short position is more likely to be created if the underwriters are concerned that, in the open market after pricing, there may be downward pressure on the price of the securities that could adversely affect investors who purchase securities in this offering. Stabilizing transactions permit bids to purchase the underlying security for the purpose of fixing the price of the security so long as the stabilizing bids do not exceed a specified maximum. Penalty bids permit the underwriters to reclaim a selling concession from a dealer when the securities originally sold by the dealer are purchased in a covering transaction to cover short positions.

Any underwriters who are qualified market makers on The Nasdaq Capital Market may engage in passive market making transactions in our common stock, preferred stock, warrants, units and debt securities, as applicable, on The Nasdaq Capital Market in accordance with Rule 103 of Regulation M, during the business day prior to the pricing of the offering, before the commencement of offers or sales of the securities. Passive market makers must comply with applicable volume and price limitations and must be identified as passive market makers. In general, a passive market maker must display its bid at a price not in excess of the highest independent bid for such security; if all independent bids are lowered below the passive market maker’s bid, however, the passive market maker’s bid must then be lowered when certain purchase limits are exceeded.

Similar to other purchase transactions, an underwriter’s purchase to cover the syndicate short sales or to stabilize the market price of our securities may have the effect of raising or maintaining the market price of our securities or preventing or mitigating a decline in the market price of our securities. As a result, the price of our securities may be higher than the price that might otherwise exist in the open market. The imposition of a penalty bid might also have an effect on the price of the securities if it discourages resales of the securities.

Neither we nor the underwriters make any representation or prediction as to the effect that the transactions described above may have on the price of the securities. If such transactions are commenced, they may be discontinued without notice at any time.

The underwriters, dealers and agents may engage in transactions with us, or perform services for us, in the ordinary course of business for which they receive compensation.

LEGAL MATTERS

Certain legal matters in connection with the offered securities will be passed upon for us by Dorsey & Whitney LLP, Salt Lake City, Utah. Any underwriters or agents will be represented by their own legal counsel, who will be identified in the applicable prospectus supplement.
