PROSPECTUS SUPPLEMENT

(To Prospectus dated February 2, 2022)

3,276,262 Shares of Common Stock

Common Warrants to Purchase up to 4,761,905 Shares of Common Stock

Pre-Funded Warrants to Purchase up to 1,485,643 Shares of Common Stock

Underwriter Warrants to Purchase up to 238,095 Shares of Common Stock

(and the shares of Common Stock underlying such Common Warrants, Pre-Funded Warrants and Underwriter Warrants)

We are offering 3,276,262 shares of our common stock, $0.0001 par value per share, pre-funded warrants (the “Pre-Funded Warrants”) to purchase 1,485,643 shares of common stock and warrants to purchase up to 4,761,905 shares of our common stock (the “Common Warrants”) pursuant to this prospectus supplement and the accompanying prospectus. The public offering price for each share of common stock and accompanying Common Warrant to purchase one share of common stock is $1.05. Each Common Warrant has an exercise price of $0.7964 per share, is exercisable immediately and will expire five years from the date of issuance.

We are offering to those purchasers whose purchase of our common stock in this offering would otherwise result in such purchaser, together with its affiliates and certain related parties, beneficially owning more than 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding common stock immediately following the consummation of this offering, in lieu of purchasing common stock, Pre-Funded Warrants to purchase up to an aggregate of shares of our common stock. Each Pre-Funded Warrant will be exercisable for one share of our common stock at any time at the option of the holder until such Pre-Funded Warrant is exercised in full, provided that the holder will be prohibited from exercising Pre-Funded Warrants for shares of our common stock if, as a result of such exercise, the holder, together with its affiliates, would own more than 4.99% (or, at the election of the purchaser, 9.99%) of the total number of shares of our common stock then issued and outstanding. However, any holder may increase or decrease such percentage to any other percentage not in excess of 9.99%, provided that any increase in such percentage shall not be effective until 61 days after such notice to us. The purchase price of each Pre-Funded Warrant and accompanying Common Warrant is equal to the purchase price per share of common stock in this offering, minus $0.0001, and the exercise price of each Pre-Funded Warrant will equal $0.0001 per share of common stock. Each Pre-Funded Warrant will be exercisable immediately upon issuance and do expire. This offering also relates to (and this prospectus supplement relates to) the shares of common stock issuable upon exercise of the Common Warrants and Pre-Funded Warrants sold in this offering.

We are also registering the Underwriter Warrants (as defined below) and the shares of our common stock that are issuable from time to time upon exercise of the Underwriter Warrants. See “Description of Securities Offered” in this prospectus supplement for additional information.

Our common stock is traded on The Nasdaq Capital Market under the symbol “RVPH.” On August 20, 2024, the last reported sales price of our common stock on The Nasdaq Capital Market was $1.14 per share. There is no established trading market for the Warrants (as defined below) and we do not expect a market to develop. We do not intend to apply for a listing for the Warrants (as defined below) on any securities exchange or other nationally recognized trading system. Without an active trading market, the liquidity of the Warrants will be limited.

Investing in our common stock involves a high degree of risk. See “Risk Factors” on page S-4 of this prospectus supplement and the documents incorporated by reference into this prospectus supplement.

Neither the Securities and Exchange Commission (“SEC”) nor any state securities commission has approved or disapproved of these securities or determined if this prospectus supplement is truthful or complete. Any representation to the contrary is a criminal offense.

Delivery of the shares of common stock and the Warrants is expected to be made on or about August 22, 2024.

This prospectus supplement and the accompanying prospectus are part of a registration statement on Form S-3 that we have filed with the SEC using a “shelf” registration process. We provide information to you about this offering of shares of our common stock and warrants in two separate documents that are bound together: (1) this prospectus supplement, which describes the specific details regarding this offering, and (2) the accompanying prospectus, which provides general information, some of which may not apply to this offering. Generally, unless the context indicates otherwise, when we refer to this “prospectus,” we are referring to both documents combined.

Company Overview

Recent Developments

RECOVER-1 Trial Results

On October 30, 2023, we announced positive topline results and successful completion of our pivotal RECOVER-1 Trial evaluating the efficacy, safety and tolerability of once-daily brilaroxazine, a serotonin dopamine signaling modulator in adults with schizophrenia. The trial successfully met its primary endpoint at the 50 mg dose, with brilaroxazine at that dose achieving a statistically significant and clinically meaningful 10.1-point reduction in Positive and Negative Syndrome Scale (PANSS) total score compared to placebo (-23.9 brilaroxazine 50 mg vs. -13.8 placebo, p<0.001) at week 4. Brilaroxazine also achieved statistically significant and clinically meaningful reductions in all major symptom domains and secondary endpoints at week 4 with the 50 mg dose vs. placebo. The 15 mg dose of brilaroxazine was numerically superior to placebo on the primary endpoint and most secondary endpoints, and reached statistical significance on two key secondary endpoints.

Key clinical safety and tolerability findings of brilaroxazine support a safe and well-tolerated profile

The clinical development plan for brilaroxazine also includes the completed positive Phase 2 REFRESH trial, an ongoing 1-year open label extension (OLE) trial evaluating long-term safety and tolerability, and a soon to be initiated registrational global, randomized 4-week Phase 3 RECOVER-2 trial (the “RECOVER-2 Trial”). We expect to report topline data from the OLE trial in Q4-2024, and we expect to initiate the registrational RECOVER-2 Trial in the third quarter of 2024, with completion anticipated in the fourth quarter of 2025. RECOVER-2 was originally designed as a 6-week study, but after discussion between Reviva and the FDA, the agency has agreed that it can be conducted as a 4-week study. In addition, the FDA indicated that it will require a long-term randomized withdrawal study post-approval to support maintenance of effect. Data from these brilaroxazine clinical trials will potentially support the planned NDA submission to the FDA in the first quarter of 2026.

Open Label Extension (OLE) Trial Enrollment Update

In August 2024, we provided the following enrollment update on our ongoing 1-year open-label extension (OLE) study evaluating the long-term safety and tolerability of brilaroxazine in patients with schizophrenia.

May 2024 Registered Direct Offering

On May 29, 2024, we closed a registered direct offering priced at the market under The Nasdaq Stock Market rules, pursuant to which we issued and sold an aggregate of 1,898,734 shares of our common stock and warrants to purchase up to 1,898,734 shares of our common stock at a combined offering price of $1.58 per share of common stock and accompanying warrant. The warrants have an exercise price of $1.455 per share, are immediately exercisable and expire five years following the date of issuance.

In connection with the May 2024 registered direct offering, we also agreed to amend certain existing warrants held by the investor in the offering to purchase up to an aggregate of 1,365,854 shares of our common stock that were previously issued to the investor in November 2023, with an exercise price of $5.00 per share, for $0.125 per amended warrant, so that the amended warrants have a reduced exercise price of $1.455 per share and expire five years following the closing of the May 2024 registered direct offering.

Warrant Amendment Agreement

The purchaser in this offering is a holder of (i) warrants to purchase up to 2,536,586 shares of common stock at an exercise price of $5.00 per share issued in November of 2023 and (ii) warrants to purchase up to 2,199,975 shares of common stock at an exercise price of $4.125 per share issued in June of 2021 (collectively, the “Existing Warrants”). Concurrent with this offering, we have entered into a Warrant Amendment Agreement (the “Warrant Amendment Agreement”) with such purchasers pursuant to which, in consideration for each such investor’s purchase of approximately $5 million of securities in this offering and the payment of $0.125 for each repriced warrant for a total of $592,070.125, we agreed to (i) reduce the exercise price of the Existing Warrants to $0.7963 per share and (ii) extend the termination date of the Existing Warrants to five years following the closing of this offering, effective upon the consummation of this offering.

Our website and the information contained on, or that can be accessed through, our website shall not be deemed to be incorporated by reference in, and are not considered part of, this prospectus supplement. You should not rely on any such information in making your decision whether to purchase our common stock or warrants.

THE OFFERING

The number of shares of common stock to be outstanding following this offering is based on 29,817,294 shares issued and outstanding at July 17, 2024 and excludes:

Except as otherwise indicated, all information in this prospectus supplement assumes no exercise of the options, warrants or pre-funded warrants referred to above (other than those Common Warrants and Pre-Funded Warrants sold in this offering).

RISK FACTORS

Before purchasing any of the securities you should carefully consider the risk factors incorporated by reference in this prospectus supplement and accompanying prospectus from our most recent Annual Report on Form 10-K and any subsequent updates described in our Quarterly Reports on Form 10-Q and Current Reports on Form 8-K, as well as the risks, uncertainties and additional information set forth in our SEC reports on Forms 10-K, 10-Q and 8-K and in the other documents incorporated by reference in this prospectus supplement and accompanying prospectus. For a description of these reports and documents, and information about where you can find them, see “Additional Information” and “Incorporation of Certain Information By Reference.” Additional risks not presently known or that we presently consider to be immaterial could subsequently materially and adversely affect our financial condition, results of operations, business and prospects.

Risks Related to this Offering

We will have broad discretion in how we use the net proceeds of this offering. We may not use these proceeds effectively, which could affect our results of operations and cause our stock price to decline.

We will have considerable discretion in the application of the net proceeds of this offering, including for any of the purposes described in the section titled “Use of Proceeds.” We currently intend to use the net proceeds from this offering, together with our existing cash and cash equivalents, to fund research and development activities, including the RECOVER-2 Trial and for working capital, and other general corporate purposes. We may use the net proceeds for purposes that do not yield a significant return or any return at all for our stockholders. Our failure to use our cash and cash equivalents 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. In addition, pending their use, we may invest the net proceeds from this offering in a manner that does not produce income or that loses value.

Sales of a substantial number of shares of our common stock, or the perception that such sales may occur, may adversely impact the price of our common stock.

Sales of a substantial number of shares of our common stock in the public markets could depress the market price of our common stock and impair our ability to raise capital through the sale of additional equity securities. The shares of our common stock held by our directors and executive officers and affiliated funds are subject to 45-day lock-up restrictions entered into in connection with this offering. Other than the shares subject to the lock-up agreements, substantially all of our outstanding shares of our common stock may be sold in the public market. If substantial additional shares are sold, or if it is perceived that they will be sold, in the public market, the trading price of our common stock could decline. Sales of a substantial number of shares of our common stock in the public market could occur at any time. In addition, the issuance of the shares of our common stock and warrants in this offering could result in resales of our common stock by our current stockholders who may be concerned about the potential ownership dilution of their holdings. In turn, these sales could have the effect of depressing the market price for our common stock. We cannot predict the effect that future sales of our common stock would have on the market price of our common stock.

You may experience immediate and substantial dilution in the book value per share of the common stock you purchase.

Because the public offering price per share (or Pre-Funded Warrant in lieu thereof) sold in this offering may be substantially higher than the book value per share of our common stock, you may suffer immediate and substantial dilution in the net tangible book value of the common stock you purchase in this offering. After giving effect to the sale in this offering of our common stock and accompanying Common Warrant at an offering price of $1.05 per share and accompanying Common Warrant, and assuming the full exercise of the Pre-Funded Warrants and no exercise of the Common Warrants and Underwriter Warrants, and after deducting underwriting discounts and commissions and estimated expenses payable by us, our as adjusted net tangible book deficit as of June 30, 2024 would have been approximately $(2.2 million), or $(0.06) per share of our common stock. This represents an immediate increase in the net tangible book value of $0.13 per share to our existing stockholders and an immediate and substantial dilution in as-adjusted net tangible book value of $1.11 per share to new investors who purchase securities in the offering. See “Dilution” for a more detailed discussion of the dilution you may incur in connection with this offering.

We do not currently intend to pay dividends on our common stock, and, consequently, investors’ ability to achieve a return on their investment will depend on appreciation in the price of our common stock.

We do not currently intend to pay any cash dividends on our common stock for the foreseeable future. Therefore, investors who purchase shares in this offering are not likely to receive any dividends on our common stock for the foreseeable future. Since we do not intend to pay dividends, investors’ ability to receive a return on their investment will depend on any future appreciation in the market value of our common stock. There is no guarantee that our common stock will appreciate or even maintain the price at which investors have purchased it.

Following this offering, we will require substantial additional capital to finance our operations and achieve our goals. If we are unable to raise capital when needed or on terms acceptable to us, we may be forced to delay, reduce or eliminate our research or product development programs, any future commercialization efforts or other operations.

Developing pharmaceutical products, including conducting preclinical studies and clinical trials, is a very time-consuming, expensive and uncertain process that takes years to complete. Our operations have consumed substantial amounts of cash since inception, and we expect our expenses to increase substantially in connection with our ongoing activities, particularly as we advance our lead product candidate, brilaroxazine, RP1208, and any future product candidates through clinical development. We will require substantial additional funding following this offering in order, among other things, to further advance the brilaroxazine program, including conducting additional clinical and regulatory development activities (including filing of an NDA) and potential commercialization activities necessary to potentially bring brilaroxazine to market for the treatment of acute and maintenance schizophrenia, if approved. We expect increased expenses as we continue our research and development, initiate additional clinical trials, seek to expand our product pipeline, seek marketing approval for our lead programs and future product candidates, if any, and invest in our organization. In addition, if we obtain marketing approval for any of our product candidates, we expect to incur significant commercialization expenses related to product manufacturing, marketing, sales and distribution. Furthermore, we have incurred and will continue to incur additional costs associated with operating as a public company, such as acquiring and retaining experienced personnel, developing new information technology systems, and other costs associated with being a public company. Also, we expect to experience ongoing and additional costs related to preparing and filing patent applications, maintaining our intellectual property and potentially expanding our office facilities. Accordingly, following this offering, we will require substantial additional capital in connection with our continuing operations.

Adequate additional financing may not be available to us on favorable terms, or at all. In addition, we may seek additional capital due to favorable market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans. If we are unable to raise capital when needed or on favorable terms, we could be forced to delay, reduce or eliminate our research and development programs, our commercialization plans or other operations. Our ability to raise capital may be adversely impacted by potential worsening global economic conditions and disruptions to and volatility in the credit and financial markets in the United States and worldwide resulting from inflation, changes in interest rates, recent turmoil in the global banking system, geopolitical instability, including the war in Ukraine, the Middle East and public health epidemics, such as the COVID-19 pandemic or future health crises, pandemics or other events, or otherwise.

There is no public market for the Warrants being offered in this offering.

There is no established public trading market for the Warrants being offered in this offering, and we do not expect a market to develop. In addition, we do not intend to apply to list the Warrants on any securities exchange or nationally recognized trading system, including The Nasdaq Capital Market. Without an active market, the liquidity of the Warrants will be limited.

Except for the right to participate in certain dividends and distributions, holders of the Common Warrants and the Pre-Funded Warrants purchased in this offering will have no rights as common stockholders until such holders exercise such warrants and acquire our common stock.

Until holders of the Common Warrants and Pre-Funded Warrants acquire shares of our common stock upon exercise of such warrants, the holders will have no rights with respect to the shares of our common stock underlying such warrants except that the holder of a Common Warrant or Pre-Funded Warrant shall be entitled to participate in certain distributions, including cash dividends, if any, to all holders of our common stock for no consideration, subject to certain ownership limitations. Upon exercise of the Common Warrants or Pre-Funded Warrants, the holders will be entitled to exercise the rights of a common stockholder only as to matters for which the record date occurs after the exercise date.

The Warrants being offered are speculative in nature.

Following this offering, the market value of the Warrants, if any, will be uncertain and there can be no assurance that the market value of the Warrants will equal or exceed their imputed offering price. The Warrants will not be listed or quoted for trading on any market or exchange. There can be no assurance that the market price of our common stock will ever equal or exceed the exercise price of the Warrants, and consequently, the Warrants may expire valueless.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus supplement, the accompanying prospectus and the documents incorporated by reference in this prospectus supplement contain, and our officers and representatives may from time to time make, “forward-looking statements,” which include information relating to future events, future financial performance, financial projections, strategies, expectations, competitive environment and regulation. Words such as “may,” “should,” “could,” “would,” “predicts,” “potential,” “continue,” “expects,” “anticipates,” “future,” “intends,” “plans,” “believes,” “estimates,” “goal,” “seek,” “project,” “strategy,” “likely,” and similar expressions, as well as statements in future tense, identify forward-looking statements. Forward-looking statements are neither historical facts, nor should they be read as a guarantee of future performance or results and may not be accurate indications of when such performance or results will be achieved. Forward-looking statements are based on information we have when those statements are made or management’s good faith belief as of that time with respect to future events, and are subject to risks and uncertainties that could cause actual performance or results to differ materially from those expressed in or suggested by the forward-looking statements. Important factors that could cause such differences include, but are not limited to:

The foregoing does not represent an exhaustive list of matters that may be covered by the forward-looking statements contained herein and in the documents incorporated by reference herein or risk factors that we are faced with that may cause our actual results to differ from those anticipate in our forward-looking statements. Factors that may affect our results include, but are not limited to, the risks and uncertainties discussed in the “Risk Factors” section on page S-4 of this prospectus, in our Annual Report on Form 10-K or in quarterly or other reports we file with the SEC from time to time.

Moreover, new risks regularly emerge and it is not possible for our management to predict or articulate all risks we face, nor can we assess the impact of all risks on our business or the extent to which any risk, or combination of risks, may cause actual results to differ from those contained in any forward-looking statements. The Private Securities Litigation Reform Act of 1995 and Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), do not protect any forward-looking statements that we make in connection with this offering. All forward-looking statements included in this prospectus supplement and in the documents incorporated by reference in this prospectus supplement are based on information available to us on the date of this prospectus or the date of the applicable document incorporated by reference. Except to the extent required by applicable laws or rules, we undertake no obligation to publicly update or revise any forward-looking statement, whether written or oral, that may be made from time to time, whether as a result of new information, future events or otherwise. All subsequent written and oral forward-looking statements attributable to us or persons acting on our behalf are expressly qualified in their entirety by the cautionary statements contained above and throughout this prospectus and in the documents incorporated by reference in this prospectus supplement. We qualify all of our forward-looking statements by these cautionary statements.

You should rely only on the information in this prospectus supplement. We have not authorized any other person to provide you with different information. If anyone provides you with different or inconsistent information, you should not rely upon it.

USE OF PROCEEDS

We estimate that our net proceeds from the sale of the shares of our common stock (or Pre-Funded Warrants in lieu thereof) and Common Warrants will be approximately $3.8 million, after deducting the underwriting discounts and commissions and estimated offering expenses payable by us and excluding the proceeds, if any, from the exercise of the Warrants issued pursuant to this offering and including the proceeds received pursuant to the Warrant Amendment Agreement..

We currently intend to use the net proceeds from this offering, together with our existing cash and cash equivalents, to fund research and development activities, including the RECOVER-2 Trial, and for working capital and other general corporate purposes.

We will require substantial additional funding following this offering in order, among other things, to further advance the brilaroxazine program, including conducting additional clinical and regulatory development activities (including filing of an NDA) and potential commercialization activities necessary to potentially bring brilaroxazine to market for the treatment of acute and maintenance schizophrenia, if approved. While we anticipate seeking additional capital in the future through further equity offerings and/or debt borrowings, or through collaboration agreements, strategic alliances, licensing arrangements or marketing and distribution arrangements, we cannot guarantee that we will be able to raise additional capital on reasonable terms or at all.

Investors are cautioned, however, that expenditures may vary substantially from these uses. Investors will be relying on the judgment of our management, who will have broad discretion regarding the application of the proceeds of this offering. The amounts and timing of our actual expenditures may vary significantly depending upon numerous factors, including the amount of cash generated by our operations and other operational factors, the progress of our development efforts, the status of and results from clinical trials, as well as any collaborations that we may enter into with third parties for our product candidates and any unforeseen cash needs. We may find it necessary or advisable to use portions of the proceeds from this offering for other purposes.

Pending other uses, we intend to invest the proceeds to us in investment-grade, interest-bearing securities such as money market funds, certificates of deposit, or direct or guaranteed obligations of the U.S. government, or hold as cash. We cannot predict whether the proceeds invested will yield a favorable, or any, return.

DILUTION

If you invest in our securities, your interest will be diluted immediately to the extent of the difference between the public offering price per share and accompanying Common Warrant or Pre-Funded Warrants and the adjusted net tangible book value per share of our common stock after this offering.

The net tangible book deficit of our common stock as of June 30, 2024, was approximately $(6.0 million), or approximately $(0.19) per share. Net tangible book deficit per share represents the amount of our total tangible assets, excluding goodwill and intangible assets, less total liabilities, divided by the total number of shares of our common stock outstanding, inclusive of shares of common stock issuable upon exercise of Pre-Funded Warrants outstanding. Dilution per share to new investors represents the difference between the amount per share paid by purchasers for each share of our common stock in this offering and the net tangible book value per deficit of our common stock immediately following the completion of this offering.

After giving effect to the sale of shares of our common stock and accompanying Common Warrants by us in this offering at a public offering price of $1.05 per share and accompanying Common Warrant, and Pre-Funded Warrants to purchase shares of common stock  and accompanying Common Warrants at the public offering price of $1.0499 per Pre-Funded Warrant and accompanying Common Warrant (which equals the public offering price of the common stock at which shares of our common stock are being sold to the public in this offering less the $0.0001 per share exercise price of each such Pre-Funded Warrant), assuming the full exercise of the Pre-Funded Warrants and no exercise of the Common Warrants or Underwriter Warrants, and including the proceeds received pursuant to the Warrant Amendment Agreement, and after deducting underwriting discounts and commissions and estimated offering expenses payable by us, our as adjusted net tangible book deficit as of June 30, 2024 would have been approximately $(2.2 million), or $(0.06) per share. This represents an immediate increase in as adjusted net tangible book value of $0.13 per share to our existing stockholders and an immediate dilution of $1.11 per share to investors purchasing securities in this offering.

The following table illustrates this dilution on a per share basis:

The foregoing tables and calculations (other than the historical net tangible book value calculation) are based on 29,817,294 shares of our common stock outstanding as of June 30, 2024, and excludes:

To the extent that any of these outstanding options or warrants are exercised or we issue additional shares under our equity incentive plans, there may 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 stockholders.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES

The following is a summary of the material U.S. federal income tax consequences of the ownership and disposition of our common stock, Common Warrants or Pre-Funded Warrants, but does not purport to be a complete analysis of all the potential tax considerations relating thereto. This summary is based upon the provisions of the Internal Revenue Code of 1986, as amended, or the Code, Treasury regulations promulgated thereunder, administrative rulings and judicial decisions, all as of the date hereof. These authorities may be changed, possibly with retroactive effect, so as to result in U.S. federal income tax consequences different from those set forth below.

This summary does not address the tax considerations arising under the laws of any U.S. state or local or any non-U.S. jurisdiction, the potential application of the Medicare contribution tax on net investment income or under U.S. federal gift and estate tax laws. In addition, this discussion does not address all tax considerations that may be applicable to an investor’s particular circumstances or to investors that may be subject to special tax rules, including, without limitation:

In addition, if a partnership or entity classified as a partnership for U.S. federal income tax purposes holds our common stock or Pre-Funded Warrants, the tax treatment of its partners generally will depend on the status of the partners and upon the activities of the partnership. Accordingly, partnerships that hold our common stock or Pre-Funded Warrants, and partners in such partnerships, should consult their tax advisors.

You are urged to consult your tax advisor with respect to the application of the U.S. federal income tax laws to your particular situation, as well as any tax consequences of the purchase, ownership and disposition of our common stock, Common Warrants or Pre-Funded Warrants arising under the U.S. federal non-income tax laws, or under the laws of any U.S. state or local or any non-U.S. taxing jurisdiction or any applicable tax treaty.  

Treatment of the Pre-Funded Warrants

Although it is not entirely free from doubt, we believe a Pre-Funded Warrant should be treated as a share of our common stock for U.S. federal income tax purposes and a holder of Pre-Funded Warrants should generally be taxed in the same manner as a holder of such shares of common stock, as described below. Accordingly, no gain or loss should be recognized upon the exercise of a Pre-Funded Warrant and, upon exercise, the holding period of a Pre-Funded Warrant should carry over to the share of common stock received. Similarly, the tax basis of the Pre-Funded Warrant should carry over to the share of common stock received upon exercise, increased by the exercise price of $0.0001 per share.

Our characterization is not binding on the IRS, and the IRS may treat our Pre-Funded Warrants as warrants to acquire shares of our common stock. In that case, the amount and character of your gain with respect to an investment in our Pre-Funded Warrants could be materially different than the discussion set forth below. Accordingly, each holder should consult his, her or its own tax advisor regarding the risks associated with the acquisition of Pre-Funded Warrants pursuant to this offering (including potential alternative characterizations). The balance of this discussion generally assumes that a Pre-Funded Warrant is treated as a share of our common stock for U.S. federal income tax purposes.

Tax Consequences to U.S. Holders of Owning and Disposing of Common Stock, Common Warrants or Pre-Funded Warrants

The following discusses the material U.S. federal income tax consideration of owning and disposing of our common stock, Common Warrants or Pre-Funded Warrants for a U.S. holder.

For purposes of this discussion, a U.S. holder is any holder (other than a partnership or entity classified as a partnership for U.S. federal income tax purposes) of our common stock, Common Warrants or Pre-Funded Warrants that, for U.S. federal income tax purposes, is:

Allocation of Purchase Price

Because our common stock and accompanying Common Warrants, or Pre-Funded Warrants and accompanying Common Warrants as applicable, are sold together, a purchaser of shares of our common stock and accompanying Common Warrants, or Pre-Funded Warrants and accompanying Common Warrants as applicable, must allocate its purchase price between each share of common stock or Pre-Funded Warrant, as applicable, and the accompanying Common Warrant based on their respective relative fair market values at the time of issuance. This allocation of the purchase price will establish the holder’s initial tax basis for U.S. federal income tax purposes for each share of common stock or Pre-Funded Warrant, as applicable, and Common Warrant. A holder’s allocation of the purchase price among the shares of common stock or Pre-Funded Warrants, as applicable, and Common Warrant is not binding on the IRS or the courts, and no assurance can be given that the IRS or the courts will agree with a holder’s allocation. Each holder should consult its own tax advisor regarding the allocation of the purchase price among the shares of common stock or Pre-Funded Warrants, as applicable, and Common Warrant.

Distributions

We do not currently intend to pay any distributions on our common stock for the foreseeable future. However, if we do pay cash or other property distributions on our common stock, those payments will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. To the extent those distributions exceed both our current and our accumulated earnings and profits, they will constitute a return of capital and will first reduce your basis in our common stock, but not below zero, and then will be treated as gain from the sale of our common stock (see “Tax Consequences to U.S. Holders of Owning and Disposing of Common Stock, Common Warrants or Pre-Funded Warrants—Gains on Sale or Other Taxable Disposition of Our Common Stock or Pre-Funded Warrants” below).

Dividends received by a corporate U.S. holder may be eligible for a dividends received deduction, subject to applicable limitations. Dividends received by certain non-corporate U.S. holders, including individuals, are generally taxed at the lower applicable capital gains rate provided certain holding period and other requirements are satisfied.

The taxation of a distribution received with respect to a Common Warrant Pre-Funded Warrant is unclear. It is possible such a distribution would be treated as a distribution on common stock as described in this section, although other treatments may also be possible. Investors should consult their tax advisors regarding the proper treatment of any distributions made in respect of the Pre-Funded Warrants.

Certain Adjustments to the Common Warrants and the Pre-Funded Warrants

Under Section 305 of the Code, an adjustment to the number of shares of common stock that will be issued on the exercise of the Common Warrants or Pre-Funded Warrants may be treated as a constructive distribution to a U.S. holder of the Common Warrants or the Pre-Funded Warrants if, and to the extent that, such adjustment has the effect of increasing a U.S. holder’s proportionate interest in our earnings and profits or assets, depending on the circumstances of such adjustment (for example, if such adjustment is to compensate for a distribution of cash or other property to our shareholders). A constructive distribution under these rules would be subject to tax in the same manner, as described above under “Tax Consequences to U.S. Holders of Owning and Disposing of Common Stock or Pre-Funded Warrants—Distributions”, as if the U.S. holders of the Common Warrants or Pre-Funded Warrants received a cash distribution from us equal to the fair market value of such increased interest resulting from the adjustment. 

Gains on Sale or Other Taxable Disposition of Our Common Stock or Pre-Funded Warrants

Upon the sale or other taxable disposition of our common stock or Pre-Funded Warrants, a U.S. holder generally will recognize capital gain or loss equal to the difference between (i) the amount of cash and the fair market value of any property received upon the sale or other taxable disposition and (ii) such U.S. holder’s adjusted tax basis in the common stock or Pre-Funded Warrants. Such capital gain or loss will be long-term capital gain or loss if the U.S. holder’s holding period in such common stock or Pre-Funded Warrant is more than one year at the time of the sale or other taxable disposition. Long-term capital gains recognized by certain non-corporate U.S. holders, including individuals, generally will be subject to reduced rates of U.S. federal income tax. The deductibility of capital losses is subject to certain limitations.

Gains on Sale or Other Taxable Disposition of Common Warrants

Upon the sale or other taxable disposition of a Common Warrant (other than by exercise), a U.S. holder will generally recognize capital gain or loss equal to the difference between the amount realized on the sale or other taxable disposition and the U.S. holder’s tax basis in the Common Warrant. This capital gain or loss will be long-term capital gain or loss if the U.S. holder’s holding period in such Common Warrant is more than one year at the time of the sale or other disposition. The deductibility of capital losses is subject to certain limitations.

Exercise of Common Warrants

A U.S. holder generally will not recognize gain or loss for U.S. federal income tax purposes on the exercise of a Common Warrant and the related receipt of common stock. A U.S. holder’s tax basis in the common stock received upon exercise of the Common Warrant generally will equal the sum of the U.S. holder’s tax basis in the Common Warrant and the exercise price. A U.S. holder’s holding period for the common stock received upon exercise of the Common Warrant will begin on the day or the day after such U.S. holder exercise the Common Warrant.

In certain circumstances, the Common Warrant may be exercised on a cashless basis. The U.S. federal income tax treatment of an exercise of a Common Warrant on a cashless basis is not clear under current law, and could differ from the consequences described above. It is possible that a cashless exercise is a non-taxable transaction, either because the exercise is not treated as a realization event or because the exercise is treated as a tax-free recapitalization for U.S. federal income tax purposes. Under either characterization, a U.S. holder’s tax basis in the common stock received generally would equal the U.S. holder’s tax basis in the Common Warrant. If the cashless exercise was not a realization event, it is unclear whether a U.S. holder’s holding period for the shares of common stock acquired pursuant to the cashless exercise will commence on the date of exercise of the Common Warrant or the day following the date of exercise of the Common Warrant. If the cashless exercise were treated as a recapitalization, the holding period of the shares of common stock acquired pursuant to it would include the holding period of the Common Warrant.

It is also possible that a cashless exercise is treated as a taxable exchange in which gain or loss would be recognized. In such event, a U.S. holder may be deemed to have surrendered Common Warrant with an aggregate fair market value equal to the exercise price for the total number of warrants to be exercised. The U.S. holder would recognize capital gain or loss in an amount equal to the difference between the fair market value of the Common Warrant deemed surrendered and the U.S. holder’s tax basis in such warrants (such gain or loss would be long-term or short-term, depending on the U.S. holder’s holding period in the Common Warrants deemed surrendered). In this case, a U.S. holder’s tax basis in the shares of common stock received pursuant to the cashless exercise would equal the sum of the U.S. holder’s tax basis in the Common Warrants exercised and the exercise price of such warrants. A U.S. holder’s holding period for the common stock received upon exercise of the Common Warrants will begin on the day or the day after such U.S. holder exercise the Common Warrant.

Due to the absence of authority on the U.S. federal income tax treatment of a cashless exercise, there can be no assurance which, if any, of the alternative tax consequences and holding periods described above would be adopted by the IRS or a court of law. Holders are urged to consult their tax advisors as to the consequences of an exercise of a Common Warrant on a cashless basis, including with respect to their holding period and tax basis in the common stock received.

Lapse of Common Warrants

If a U.S. holder allows a Common Warrant to expire unexercised, such holder will generally recognize a capital loss for U.S. federal income tax purposes in an amount equal to such holder’s tax basis in the Common Warrant. Any such loss generally will be a capital loss and will be long-term capital loss if the Common Warrant is held for more than one year. The deductibility of capital losses is subject to limitations.

Contingent Payments on the Common Warrants

The Common Warrants entitle a holder to receive payments upon the occurrence of certain contingencies, including a distribution on shares of our common stock or our failure to deliver shares of common stock upon exercise of a Common Warrant. The tax treatment of such payments, if made, is subject to substantial uncertainty. Holders should consult their own tax advisors as to the appropriate U.S. federal income tax treatment of any such contingent payments that may be made to them in respect of the Common Warrants.

Backup Withholding and Information Reporting

Information reporting requirements generally will apply to payments of distributions (including constructive distributions) on the common stock, Common Warrant and Pre-Funded Warrants and to the proceeds of a sale or other disposition of common stock, Common Warrant and Pre-Funded Warrants paid by us to a U.S. Holder unless such U.S. Holder is an exempt recipient, such as a corporation. Backup withholding will apply to those payments if the U.S. Holder fails to provide the holder’s taxpayer identification number, or certification of exempt status, or if the holder otherwise fails to comply with applicable requirements to establish an exemption.

Backup withholding is not an additional tax; rather, the U.S. income tax liability of persons subject to backup withholding will be reduced by the amount of tax withheld. If withholding results in an overpayment of taxes, a refund or credit may generally be obtained from the IRS, provided that the required information is furnished to the IRS in a timely manner.

Tax Consequences to Non-U.S. Holders of Owning and Disposing of Common Stock

The following discusses the material U.S. federal income tax consequences of acquiring, owning and disposing of shares of our common stock for a non-U.S. holder.

For purposes of this discussion, a non-U.S. holder is any holder (other than a partnership or entity classified as a partnership for U.S. federal income tax purposes) of our common stock that, for U.S. federal income tax purposes, is not:

Distributions

We have never paid cash distributions on our common stock and do not anticipate doing so in the foreseeable future. However, if we do pay cash or other property distributions on our common stock, those payments will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. To the extent those distributions exceed both our current and our accumulated earnings and profits, they will constitute a return of capital and will first reduce your basis in our common stock, but not below zero, and then will be treated as gain from the sale of our common stock (see “Tax Consequences to Non-U.S. Holders of Owning and Disposing of Common Stock, Common Warrants or Pre-Funded Warrants—Gains on Sale or Other Taxable Disposition of Our Common Stock, Common Warrants or Pre-Funded Warrants” below).

Subject to the discussion below under the headings “Tax Consequences to Non-U.S. Holders of Owning and Disposing of Common Stock, Common Warrants or Pre-Funded Warrants—Backup Withholding and Information Reporting” and “Tax Consequences to Non-U.S. Holders of Owning and Disposing of Common Stock, Common Warrants or Pre-Funded Warrants—Foreign Account Tax Compliance Act,” any dividend paid to you generally will be subject to U.S. withholding tax either at a rate of 30% of the gross amount of the dividend or such lower rate as may be specified by an applicable income tax treaty. In order to receive a reduced treaty rate, you must provide us with an Internal Revenue Service, or IRS, Form W-8BEN, IRS Form W-8BEN-E or other appropriate version of IRS Form W-8 certifying qualification for the reduced rate. If you hold our common stock through a financial institution or other agent acting on your behalf, you will be required to provide appropriate documentation to the agent, which then will be required to provide certification to us or our paying agent, either directly or through intermediaries.

Dividends received by you that are effectively connected with your conduct of a U.S. trade or business (and, if required by an applicable income tax treaty, are attributable to a permanent establishment maintained by you in the United States) are taxed at the same rates applicable to U.S. persons, net of certain deductions and credits. Payments of such effectively connected dividends that are included in your gross income generally are exempt from the withholding tax discussed in the preceding paragraph. In order to obtain this exemption, you must provide us (or the appropriate agent acting on your behalf, as discussed in the preceding paragraph) with an IRS Form W-8ECI or other applicable IRS Form W-8 properly certifying such exemption. In addition, if you are a corporate non-U.S. holder, dividends you receive that are effectively connected with your conduct of a U.S. trade or business may also be subject to a branch profits tax at a rate of 30% or such lower rate as may be specified by an applicable income tax treaty.

If you are eligible for a reduced rate of withholding tax pursuant to a tax treaty, you may be able to obtain a refund of any excess amounts currently withheld if you timely file an appropriate claim for refund with the IRS.

Distributions on our common stock will also be subject to the discussion below under the headings “Backup Withholding and Information Reporting” and “Foreign Account Tax Compliance Act.”

The taxation of a distribution received with respect to a Common Warrant or a Pre-Funded Warrant is unclear. It is possible such a distribution would be treated as a distribution on common stock as described in this section, although other treatments may also be possible. Investors should consult their tax advisors regarding the proper treatment of any such distribution made in respect of the Common Warrants or Pre-Funded Warrants.

Certain Adjustments to the Common Warrants and the Pre-Funded Warrants

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

Gains on Sale or Other Taxable Disposition of Our Common Stock, Common Warrants or Pre-Funded Warrants

In general, subject to the discussion below under the headings “Tax Consequences to Non-U.S. Holders of Owning and Disposing of Common Stock, Common Warrants or Pre-Funded Warrants—Backup Withholding and Information Reporting” and “Tax Consequences to Non-U.S. Holders of Owning and Disposing of Common Stock, Common Warrants or Pre-Funded Warrants—Foreign Account Tax Compliance Act,” you will not be subject to U.S. federal income tax or withholding tax on any gain realized upon the sale or other disposition of our common stock, Common Warrants or Pre-Funded Warrants unless:

Common Warrants

The U.S. federal income tax treatment of a non-U.S. holder’s exercise of a Common Warrant, or the lapse of a Common Warrant held by a non-U.S. holder, generally will correspond to the U.S. federal income tax treatment of the exercise or lapse of a Common Warrant by a U.S. holder, as described under “Tax Consequences to U.S. Holders of Owning and Disposing of Common Stock, Common Warrants or Pre-Funded Warrants — Exercise of Common Warrants” and “Tax Consequences to U.S. Holders of Owning and Disposing of Common Stock, Common Warrants, or Pre-Funded Warrants — Lapse of Common Warrants”  above, although to the extent a cashless exercise results in a taxable exchange, the rules described above under “Tax Consequences to Non-U.S. Holders of Owning and Disposing of Common Stock, Common Warrants, or Pre-Funded Warrants — Gains on Sale or Other Taxable Disposition of Our Common Stock, Common Warrants or Pre-Funded Warrants” would apply.

If contingent payments are made with respect to a Common Warrant, as described above under “Tax Consequences to U.S. Holders of Owning and Disposing of Common Stock, Common Warrants or Pre-Funded Warrants — Contingent Payments on the Common Warrants”, such payments may be subject to a U.S. withholding tax. Any U.S. federal income tax required to be withheld on any portion of such contingent payment may be withheld from common stock delivered, sales proceeds subsequently paid or credited, or other amounts payable or distributable to a non-U.S. holder.

Backup Withholding and Information Reporting

Generally, we, or the applicable paying agent, must report annually to the IRS the amount of dividends paid to you, your name and address, and the amount of tax withheld, if any. A similar report will be sent to you. Pursuant to applicable income tax treaties or other agreements, the IRS may make these reports available to tax authorities in your country of residence.

Payments of dividends or of proceeds on the disposition of our common stock, Common Warrants or Pre-Funded Warrants made to you may be subject to additional information reporting and backup withholding at a current rate of 24% unless you establish an exemption, for example, by properly certifying your non-U.S. status on an IRS Form W-8BEN, IRS Form W-8BEN-E or another appropriate version of IRS Form W-8. Notwithstanding the foregoing, backup withholding and information reporting may apply if either we or our paying agent has actual knowledge, or reason to know, that you are a U.S. person.

Backup withholding is not an additional tax; rather, the U.S. income tax liability of persons subject to backup withholding will be reduced by the amount of tax withheld. If withholding results in an overpayment of taxes, a refund or credit may generally be obtained from the IRS, provided that the required information is furnished to the IRS in a timely manner.

Foreign Account Tax Compliance Act

The Foreign Account Tax Compliance Act, or FATCA, imposes a U.S. federal withholding tax of 30% on dividends (including deemed dividends) paid on our common stock, Common Warrants or Pre-Funded Warrants to a “foreign financial institution” (as specifically defined for this purpose) unless such institution enters into an agreement with the U.S. government to, among other things, withhold on certain payments and to collect and provide to the U.S. tax authorities substantial information regarding U.S. account holders of such institution (which includes certain equity and debt holders of such institution, as well as certain account holders that are foreign entities with U.S. owners) or otherwise establishes an exemption from FATCA withholding. FATCA also generally imposes a U.S. federal withholding tax of 30% on dividends to a “non-financial foreign entity” (as specifically defined for this purpose) unless such entity provides the withholding agent with either a certification that it does not have any substantial direct or indirect U.S. owners or provides information regarding direct and indirect U.S. owners of the entity or otherwise establishes an exemption from FATCA withholding. Because we may not know the extent to which a distribution is a dividend for U.S. federal income tax purposes at the time it is made, for purposes of these withholding rules we or the applicable withholding agent may treat the entire distribution as a dividend. While withholding under FATCA would have applied also to payments of gross proceeds from the sale or other disposition of our common stock, Common Warrants or Pre-Funded Warrants on or after January 1, 2019, proposed Treasury Regulations eliminate FATCA withholding on payments of gross proceeds entirely. Taxpayers generally may rely on these proposed Treasury Regulations until final Treasury Regulations are issued. The withholding tax on dividends will apply regardless of whether the payment otherwise would be exempt from U.S. nonresident and backup withholding tax, including under the exemptions described above. An intergovernmental agreement between the United States and an applicable foreign country may modify the requirements described in this section. Under certain circumstances, you may be eligible for refunds or credits of tax withheld pursuant to the rules described in this section. You should consult your tax advisors regarding these withholding provisions.

The preceding discussion of U.S. federal tax considerations is for general information only. It is not tax advice. Each prospective investor should consult its own tax advisor regarding the particular U.S. federal, state and local and non-U.S. tax consequences of purchasing, owning and disposing of our common stock, Common Warrants or Pre-Funded Warrants, including the consequences of any proposed change in applicable laws.

DESCRIPTION OF SECURITIES OFFERED

We are offering 3,276,262 shares of our common stock (or Pre-Funded Warrants in lieu thereof) and Common Warrants to purchase 4,761,905 shares of our common stock. We are also registering: (i) the shares of common stock issuable from time to time upon exercise of the Common Warrants and the Pre-Funded Warrants offered hereby and (ii) the Underwriter Warrants and the shares of our common stock that are issuable from time to time upon exercise of the Underwriter Warrants. 

Common Stock

See “Description of Capital Stock” on page 7 of the accompanying prospectus for a description of the material terms of our common stock.

Common Warrants

The following is a summary of the material terms and provisions of the Common Warrants that are being offered hereby. This summary is subject to and qualified in its entirety by the form of Common Warrant, which has been provided to the investors in this offering and 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. Prospective investors should carefully review the terms and provisions of the form of Common Warrant for a complete description of the terms and conditions of the Common Warrants.

Duration and Exercise Price

The Common Warrants offered hereby will have an exercise price of $0.7964 per share. The warrants will be immediately exercisable upon issuance and will be exercisable for five years from the date of issuance. 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. The Common Warrants will be issued in certificated form only.

Exercisability

The Common 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 Common 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 Common 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 Common Warrants. Purchasers in this offering may also elect prior to the issuance of Common Warrants to have the initial exercise limitation set at 9.99% of our outstanding shares of common stock.

Cashless Exercise

If at the time of exercise of the Common Warrants there is no effective registration statement registering, or the prospectus contained therein is not available for the resale of the shares of common stock issuable upon exercise of the Common Warrants, then the Common Warrants will only be exercisable on a “cashless exercise” basis under which the holder will receive upon such exercise a net number of common shares determined according to a formula set forth in the Common Warrants.

Fundamental Transactions

In the event of any fundamental transaction, as described in the 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 warrant, the holder will have the right to receive as alternative consideration, for each share 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 Common Warrant is exercisable immediately prior to such event. In certain circumstances, the holder will have the right to receive the Black Scholes Value of the Common Warrant calculated pursuant to a formula set forth in the Common Warrants, payable either in cash or in the same type or form of consideration that is being offered and being paid to the holders of our common stock as described in the Common Warrants.

Transferability

In accordance with its terms and subject to applicable laws, a Common Warrant may be transferred at the option of the holder upon surrender of the Common 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 Common Warrant. 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 the Common Warrants, and we do not expect a market to develop. We do not intend to apply for a listing for the Common Warrants on any securities exchange or other nationally recognized trading system. Without an active trading market, the liquidity of the Common Warrants will be limited.

Rights as a Shareholder

Except as otherwise provided in the Common Warrants or by virtue of the holders’ ownership of shares of common stock, the holders of the Common 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 Common Warrants.

Pre-Funded Warrants

The following summary of certain terms and provisions of Pre-Funded Warrants that are being offered hereby is not complete and is subject to, and qualified in its entirety by, the provisions of the Pre-Funded Warrant, the form of which will be filed 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. Prospective investors should carefully review the terms and provisions of the form of the Pre-Funded Warrant for a complete description of the terms and conditions of the Pre-Funded Warrants. Pre-Funded Warrants will be issued in certificated form only.

Duration and Exercise Price

Each Pre-Funded Warrant offered hereby will have an initial exercise price per share equal to $0.0001. The exercise price and number of shares of common stock issuable upon exercise is subject to appropriate adjustment in the event of stock dividends, stock splits, reorganizations or similar events affecting our common stock and the exercise price. The Pre-Funded Warrants do not expire.

Exercisability

The Pre-Funded Warrants are exercisable at any time on or after their original issuance. The Pre-Funded 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 our 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 Pre-Funded Warrant to the extent that the holder would own more than 4.99% (or, at the election of the purchaser, 9.99%) of the outstanding shares of common stock immediately after exercise. No fractional shares of common stock will be issued in connection with the exercise of a Pre-Funded Warrant. In lieu of fractional shares, we will, at our election, either round up to the next whole share or pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the exercise price. However, any holder of a Pre-Funded Warrant may increase or decrease such percentage to any other percentage not in excess of 9.99% upon at least 61 days’ prior notice from the holder to us. For purposes of the foregoing, “attribution affiliates” means, collectively, the following persons and entities with respect to any holder: (i) its direct or indirect affiliates, (ii) any person acting or who could be deemed to be acting as a Section 13(d) “group” together with the holder or any attribution parties and (iii) any other persons whose beneficial ownership of our common stock would or could be aggregated with the holder and/or any other attribution parties for purposes of Section 13(d) or Section 16 of the Exchange Act.

Cashless Exercise

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 Pre-Funded Warrants.

Fundamental Transactions

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

Transferability

Subject to applicable laws, the Pre-Funded Warrants may be offered for sale, sold, transferred or assigned without our consent. The ownership of the Pre-Funded Warrants and any transfers of the Pre-Funded Warrants will be registered in a warrant register maintained by the warrant agent. We will initially act as warrant agent.

Exchange Listing

There is no established trading market for the Pre-Funded Warrants. We do not intend to list the Pre-Funded Warrants on any securities exchange or nationally recognized trading system.

Rights as a Stockholder

Except as otherwise provided in the Pre-Funded Warrants or by virtue of such holder’s ownership of shares of our common stock, the holders of the Pre-Funded Warrants do not have the rights or privileges of holders of our common stock, including any voting rights, until such Pre-Funded Warrant holders exercise their Pre-Funded Warrants, except that the holder of a Pre-Funded Warrant shall be entitled to participate in certain distributions, including cash dividends, if any, to all holders of our common stock for no consideration, subject to certain ownership limitations.

Underwriter Warrants 

Upon the closing of this offering, we have agreed to issue to the underwriter, or its designees, warrants to purchase a number of shares of common stock equal to an aggregate of 5% of the total number of shares and Pre-Funded Warrants sold in this public offering, including any shares of our common stock sold pursuant to the underwriter’s option to purchase additional shares of our common stock. The Underwriter Warrants will be exercisable at a per share exercise price equal to 125% of the offering price per share and accompanying Common Warrant, or $1.3125. The Underwriter Warrants are exercisable commencing six months after closing of this offering, and will be exercisable for a period of five years from the date of issuance. The Underwriter Warrants and the shares of common stock issuable upon the exercise thereof are being registered on the registration statement of which this prospectus supplement is a part.

UNDERWRITING

We have entered into an underwriting agreement with Titan Partners Group LLC, a division of American Capital Partners, LLC, or the underwriter, with respect to the securities subject to this offering.

Subject to certain conditions, we have agreed to sell to the underwriter such securities listed next to their names in the below table at the public offering price less the underwriting discounts and commissions set forth on the cover page of this prospectus supplement.

The underwriting agreement provides that the obligation of the underwriter to purchase the shares of common stock, Common Warrants and Pre-Funded Warrants offered by this prospectus supplement and the accompanying prospectus is subject to certain conditions. The underwriter is obligated to purchase all of the shares of common stock, Common Warrants and Pre-Funded Warrants offered hereby. The underwriter is offering the securities, subject to prior sale, when, as and if issued to and accepted by it, subject to approval of legal matters by its counsel, and other conditions contained in the underwriting agreement. The underwriter reserves the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

Discounts, Commissions and Expenses 

The underwriter proposes to offer the shares of common stock, Common Warrants and Pre-Funded Warrants purchased pursuant to the underwriting agreement to the public at the public offering price set forth on the cover page of this prospectus supplement and to certain dealers at that price less a concession not in excess of $0.084 per share and accompanying Common Warrant and $0.084 per Pre-Funded Warrant. After this offering, the public offering price and concession may be changed by the underwriter. No such change shall change the amount of proceeds to be received by us as set forth on the cover page of this prospectus supplement.

In connection with the sale of the common stock to be purchased by the underwriter, the underwriter will be deemed to have received compensation in the form of underwriting commissions and discounts. The underwriting commissions and discounts will be 8% of the gross proceeds of this offering, or $0.084 per share of common stock or Pre-Funded Warrant set forth on the cover page of this prospectus supplement.

We will also be responsible for and will pay all expenses relating to the offering, including without limitation, reasonable out-of-pocket expenses incurred by the underwriter that we have agreed to reimburse the underwriter up to a maximum amount of $125,000, including the reasonable fees and disbursements of its counsel.

We have also paid an advance of $15,000 to the underwriter, which will be applied against the accountable expenses that will be paid by us to the underwriter in connection with this offering. This payment will be returned to us to the extent not actually incurred by the underwriter in accordance with Rule 5110(g)(4)(A) of the Financial Industry Regulatory Authority, or FINRA.

We estimate that our total offering expenses for this offering, net of the underwriting discounts and commissions, will be approximately $790,000.

The following table summarizes the underwriting discounts and commissions and proceeds, before expenses, to us assuming no exercise of the Warrants in this offering:

Underwriter Warrants 

Upon the closing of this offering, we have agreed to issue to the underwriter, or its designees, warrants to purchase a number of shares of common stock equal to an aggregate of 5% of the total number of shares of common stock and Pre-Funded Warrants sold in this public offering. The Underwriter Warrants will be exercisable at a per share exercise price equal to 125% of the offering price 125% of the offering price per share and accompanying Common Warrant, or $1.3125. The Underwriter Warrants are exercisable commencing six months after closing of this offering, and will be exercisable for a period of five years from the date of issuance. The Underwriter Warrants and the shares of common stock issuable upon the exercise thereof are being registered on the registration statement of which this prospectus supplement is a part.

The Underwriter Warrants and the shares of common stock underlying the Underwriter Warrants have been deemed compensation by FINRA, and are therefore subject to a 180-day lock-up pursuant to Rule 5110(e)(1) of FINRA. Neither the underwriter nor its permitted assignees under such rule, may sell, transfer, assign, pledge, or hypothecate the Underwriter Warrants or the securities underlying the Underwriter Warrants, nor will the underwriter engage in any hedging, short sale, derivative, put, or call transaction that would result in the effective economic disposition of the Underwriter Warrants or the underlying shares for a period of 180 days from the date of commencement of sales in this offering.

Additionally, the Underwriter Warrants may not be sold, transferred, assigned, pledged or hypothecated for a 180-day period following the date of commencement of sales in this offering, except to any underwriter and selected dealer participating in this offering and their bona fide officers or partners. The Underwriter Warrants will provide for adjustment in the number and price of the Underwriter Warrants and the shares of common stock underlying such Underwriter Warrants in the event of recapitalization, merger, stock split or other structural transaction, or a future financing undertaken by us.

Indemnification 

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

Lock-Up Agreements 

We have agreed that, for a period of 45 days after from the closing of this offering, without the prior written consent of the underwriter, and subject to certain exceptions, neither we nor any of our subsidiaries shall issue, enter into any agreement to issue or announce the issuance or proposed issuance of any shares of our common stock or common stock equivalents or file any registration statement or amendment or supplement thereto, other than this prospectus supplement. We have also agreed that from the date of the underwriting agreement until the 180 day anniversary of the closing of this offering, without the prior consent of the underwriter and subject to certain exceptions, we will not undertake any offering of our securities involving a “Variable Rate Transaction” ​(as defined in the underwriting agreement).

In addition, each of our directors and officers has entered into a lock-up agreement with the underwriter. Under the lock-up agreements, for a period of 45 days from the closing of this offering, without the prior written consent of the underwriter, the foregoing persons may not, subject to certain exceptions, offer, sell, contract to sell, lend, hypothecate, pledge or otherwise dispose of (or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition, whether by actual disposition or effective economic disposition due to cash settlement or otherwise, by such person or any affiliate or any person in privity with such person), directly or indirectly, any shares of our capital stock or any securities convertible into or exercisable or exchangeable for shares of capital stock.

Electronic Distribution 

This prospectus supplement and the accompanying prospectus may be made available in electronic format on websites or through other online services maintained by the underwriter or by its affiliates. In those cases, prospective investors may view offering terms online and prospective investors may be allowed to place orders online.

Passive Market Making 

In connection with this offering, the underwriter and selling group members may also engage in passive market making transactions in our common stock. Passive market making consists of displaying bids limited by the prices of independent market makers and effecting purchases limited by those prices in response to order flow. Rule 103 of Regulation M promulgated by the SEC limits the amount of net purchases that each passive market maker may make and the displayed size of each bid. Passive market making may stabilize the market price of the shares of common stock at a level above that which might otherwise prevail in the open market and, if commenced, may be discontinued at any time.

Nasdaq Capital Market Listing 

Our common stock is listed on The Nasdaq Capital Market under the symbol “RVPH.” The last reported sale price of our common stock on August 20, 2024 was $1.14 per share. There is no established trading market for the Warrants, and we do not expect a trading market to develop. We do not intend to list the Warrants on any securities exchange or nationally recognized trading system. Without a trading market, the liquidity of the Warrants will be extremely limited.

Other Relationships 

The underwriter is a full-service financial institution engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, principal investment, hedging, financing and brokerage activities. The underwriter and its affiliates may, from time to time, engage in transactions with and perform services for us in the ordinary course of its business for which it may receive customary fees and reimbursement of expenses. In the ordinary course of its various business activities, the underwriter and its affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (which may include bank loans and/or credit default swaps) for its own account and for the accounts of its customers and may at any time hold long and short positions in such securities and instruments. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. The underwriter and its affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

PROSPECTUS SUMMARY

The following summary highlights some information from this prospectus. It is not complete and does not contain all of the information that you should consider before making an investment decision.

About Us

We are a clinical-stage biopharmaceutical company that discovers, develops and seeks to commercialize next-generation therapeutics for diseases representing significant unmet medical needs and burden to society, patients, and their families. Our current pipeline focuses on the central nervous system, respiratory, and metabolic diseases. We use a chemical genomics driven technology platform and proprietary chemistry to develop new medicines. Our pipeline currently has two drug candidates, RP5063 (Brilaroxazine) and RP1208. Both are new chemical entities discovered in-house. We have been granted composition of matter patents for both RP5063 and RP1208 in the United States (U.S.), Europe, and several other countries.

Our lead drug candidate, RP5063, is ready for continued clinical development for multiple neuropsychiatric indications. These include schizophrenia, bipolar disorder (BD), major depressive disorder (MDD), behavioral and psychotic symptoms, dementia or Alzheimer’s disease (BPSD), Parkinson’s disease psychosis (PDP), and attention deficit hyperactivity disorder (ADHD). Furthermore, RP5063 is also ready for clinical development for two respiratory indications - pulmonary arterial hypertension (PAH) and idiopathic pulmonary fibrosis (IPF). The U.S. Food and Drug Administration (FDA) has granted Orphan Drug designation to RP5063 for the treatment of PAH in November 2016 and IPF in April 2018.

On January 10, 2022, the FDA notified us that we may proceed with our Phase 3 trial for RP5063. We plan to initiate the trial in the first quarter of 2022.

Our primary focus is to complete the clinical development of RP5063 for the treatment of acute and maintenance schizophrenia.

Subject to the receipt of additional financing, we may also continue the clinical development of RP5063 for the treatment of BD, MDD, BPSD, PDP, ADHD, PAH and IPF. Moreover, subject to the receipt of additional financing, we may also advance the development of our second drug candidate, RP1208, for the treatment of depression and obesity.

Business Combination and Domestication

On December 14, 2020, our predecessor company, formerly known as Tenzing Acquisition Corp., a British Virgin Islands exempted company (“Tenzing”), and Reviva Pharmaceuticals, Inc., a Delaware corporation (together with its consolidated subsidiaries, “Old Reviva”), consummated the transactions contemplated by the Agreement and Plan of Merger, dated as of July 20, 2020 (as amended, the “Merger Agreement”), by and among Tenzing, Tenzing Merger Subsidiary Inc., a Delaware corporation and wholly-owned subsidiary of Tenzing (“Merger Sub”), Old Reviva, and the other parties thereto. Pursuant to the Merger Agreement, Merger Sub merged with and into Old Reviva, with Old Reviva surviving as our wholly owned subsidiary. We refer to this transaction as the “Business Combination.” In connection with and one day prior to the completion of the Business Combination, Tenzing re-domiciled out of the British Virgin Islands and continued as a company incorporated in the State of Delaware, and changed its name to Reviva Pharmaceuticals Holdings, Inc. Prior to the completion of the Business Combination, the Company was a shell company. Following the Business Combination, the business of Old Reviva is the business of the Company.

Old Reviva was incorporated in the state of Delaware on May 1, 2006 and its subsidiary, Reviva Pharmaceuticals India Pvt. Ltd., was incorporated on December 23, 2014. Tenzing was formed pursuant to the laws of the British Virgin Islands on March 20, 2018.

Implications of Being an Emerging Growth Company

We are an “emerging growth company” as defined in Section 2(a)(19) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). As such, we are eligible for and intend to take advantage of certain exemptions from various reporting requirements applicable to other public companies that are not emerging growth companies for as long as we continue to be an emerging growth company, including, but not limited to, (i) the exemption from the auditor attestation requirements with respect to internal control over financial reporting under Section 404(b) of the Sarbanes-Oxley Act of 2002, as amended, (the “Sarbanes Oxley Act”), (ii) the exemptions from say-on-pay, say-on-frequency and say-on-golden parachute voting requirements and (iii) reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements.

We will remain an emerging growth company until the earlier of: (i) the last day of the fiscal year (a) following the fifth anniversary of the closing of Tenzing’s initial public offering, (b) in which we have total annual gross revenue of at least $1.07 billion, or (c) in which we are deemed to be a “large accelerated filer” under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which would occur if the market value of our common equity held by non-affiliates exceeds $700.0 million as of the last business day of our most recently completed second fiscal quarter; or (ii) the date on which we have issued more than $1.0 billion in non-convertible debt securities during the prior three-year period.

In addition, the JOBS Act provides that an emerging growth company can take advantage of an extended transition period for complying with new or revised accounting standards. This allows an emerging growth company to delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have elected to avail ourselves of this extended transition period and, as a result, we will adopt new or revised accounting standards on the relevant dates on which adoption of such standards is required for non-public companies instead of the dates required for other public companies.

RISK FACTORS

Before purchasing any of the securities you should carefully consider the risk factors incorporated by reference in this prospectus from our most recent Annual Report on Form 10-K and any subsequent updates described in our Quarterly Reports on Form 10-Q and Current Reports on Form 8-K, as well as the risks, uncertainties and additional information set forth in our SEC reports on Forms 10-K, 10-Q and 8-K and in the other documents incorporated by reference in this prospectus. For a description of these reports and documents, and information about where you can find them, see “Additional Information” and “Incorporation of Certain Information By Reference.” Additional risks not presently known or that we presently consider to be immaterial could subsequently materially and adversely affect our financial condition, results of operations, business and prospects.

Summary Risk Factors

Our business is subject to numerous risks and uncertainties, including those in the risk factors incorporated by reference in this prospectus as described above. These risks include, but are not limited to, the following:

FORWARD-LOOKING STATEMENTS

This prospectus and the documents incorporated by reference in this prospectus contain, and our officers and representatives may from time to time make, “forward-looking statements,” which include information relating to future events, future financial performance, financial projections, strategies, expectations, competitive environment and regulation. Words such as “may,” “should,” “could,” “would,” “predicts,” “potential,” “continue,” “expects,” “anticipates,” “future,” “intends,” “plans,” “believes,” “estimates,” “goal,” “seek,” “project,” “strategy,” “likely,” and similar expressions, as well as statements in future tense, identify forward-looking statements. Forward-looking statements are neither historical facts, nor should they be read as a guarantee of future performance or results and may not be accurate indications of when such performance or results will be achieved. Forward-looking statements are based on information we have when those statements are made or management’s good faith belief as of that time with respect to future events, and are subject to risks and uncertainties that could cause actual performance or results to differ materially from those expressed in or suggested by the forward-looking statements. Important factors that could cause such differences include, but are not limited to:

The foregoing does not represent an exhaustive list of matters that may be covered by the forward-looking statements contained herein and in the documents incorporated by reference herein or risk factors that we are faced with that may cause our actual results to differ from those anticipate in our forward-looking statements. Factors that may affect our results include, but are not limited to, the risks and uncertainties discussed in the “Risk Factors” section on page 3 of this prospectus, in our Annual Report on Form 10-K or in other reports we file with the Securities and Exchange Commission.

Moreover, new risks regularly emerge and it is not possible for our management to predict or articulate all risks we face, nor can we assess the impact of all risks on our business or the extent to which any risk, or combination of risks, may cause actual results to differ from those contained in any forward-looking statements. The Private Securities Litigation Reform Act of 1995 and Section 27A of the Securities Act of 1933, as amended, do not protect any forward-looking statements that we make in connection with this offering. All forward-looking statements included in this prospectus and in the documents incorporated by reference in this prospectus are based on information available to us on the date of this prospectus or the date of the applicable document incorporated by reference. Except to the extent required by applicable laws or rules, we undertake no obligation to publicly update or revise any forward-looking statement, whether written or oral, that may be made from time to time, whether as a result of new information, future events or otherwise. All subsequent written and oral forward-looking statements attributable to us or persons acting on our behalf are expressly qualified in their entirety by the cautionary statements contained above and throughout this prospectus and in the documents incorporated by reference in this prospectus. We qualify all of our forward-looking statements by these cautionary statements.

You should rely only on the information in this prospectus. We have not authorized any other person to provide you with different information. If anyone provides you with different or inconsistent information, you should not rely upon it.

USE OF PROCEEDS

Unless we inform you otherwise in the prospectus supplement, we will use the net proceeds from the sale of the securities offered by this prospectus and the exercise price from the exercise of any convertible securities, if any, to fund research and development activities, including clinical and regulatory development and the continued development of our drug candidates, including RP5063 and RP1208, acquisitions or investments in businesses, products or technologies that are complementary to our own, and for working capital and other general corporate purposes.

When particular securities are offered, the prospectus supplement relating to that offering will set forth our intended use of the net proceeds received from the sale of those securities we sell. Pending the application of the net proceeds for these purposes, we expect to invest the proceeds in short-term, interest-bearing instruments or other investment-grade securities.

THE SECURITIES WE MAY OFFER

General

The descriptions of the securities contained in this prospectus, together with the applicable prospectus supplements, summarize all of the material terms and provisions of the various types of securities that we may offer. We will describe in the applicable prospectus supplement relating to any securities the particular terms of the securities offered by that prospectus supplement. If we indicate in the applicable prospectus supplement, the terms of the securities may differ from the terms we have summarized below. We may also include in the prospectus supplement information about material United States federal income tax considerations relating to the securities, and the securities exchange, if any, on which the securities will be listed.

We may sell from time to time, in one or more offerings:

In this prospectus, we refer to the common stock, preferred stock, debt securities, subscription rights, warrants and units collectively as “securities.” The total dollar amount of all securities that we may sell will not exceed $150,000,000.

If we issue debt securities at a discount from their original stated principal amount, then, for purposes of calculating the total dollar amount of all securities issued under this prospectus, we will treat the initial offering price of the debt securities as the total original principal amount of the debt securities.

This prospectus may not be used to consummate a sale of securities unless it is accompanied by a prospectus supplement.

DESCRIPTION OF CAPITAL STOCK

General

Our authorized capital stock consists of:

As of close of business on January 20, 2022, 15,133,286 shares of our common stock were issued and outstanding and no shares of our preferred stock were issued and outstanding.

The additional shares of our authorized capital stock available for issuance may be issued at times and under circumstances so as to have a dilutive effect on earnings per share and on the equity ownership of the holders of our common stock. The ability of our board of directors to issue additional shares of stock could enhance the board’s ability to negotiate on behalf of the stockholders in a takeover situation but could also be used by the board to make a change-in-control more difficult, thereby denying stockholders the potential to sell their shares at a premium and entrenching current management. The following description is a summary of the material provisions of our capital stock. You should refer to our amended and restated certificate of incorporation and bylaws, both of which are on file with the SEC as exhibits to previous SEC filings, for additional information. The summary below is qualified by provisions of applicable law.

Common Stock

Voting. The holders of our common stock are entitled to one vote for each share held of record on all matters on which the holders are entitled to vote (or consent pursuant to written consent). When a quorum is present at any meeting of stockholders, any matter before any such meeting (other than an election of a director or directors) shall be decided by a majority of the votes properly cast on such matter, except where a different vote is required by law, by the rules or regulations of any stock exchange applicable to us, or pursuant to any regulation applicable to us or our securities, or matters relating solely to the terms of preferred stock, in which case, such different vote shall apply. A majority in voting power of the shares entitled to vote at the meeting, present in person or represented by proxy, shall constitute a quorum at any meeting of stockholders. Directors are elected by a plurality of the votes present in person or represented by proxy and entitled to vote.

Dividends. The holders of our common stock are entitled to receive, ratably, dividends only if, when and as declared by our board of directors out of funds legally available therefor and after provision is made for each class of capital stock having preference over our common stock.

Liquidation Rights. In the event of our liquidation, dissolution or winding-up, the holders of our common stock are entitled to share, ratably, in all assets remaining available for distribution after payment of all liabilities and after provision is made for each class of capital stock having preference over our common stock.

Conversion Right. The holders of our common stock have no conversion rights.

Preemptive and Similar Rights. The holders of our common stock have no preemptive or similar rights.

Redemption/Put Rights. There are no redemption or sinking fund provisions applicable to our common stock. All of the outstanding shares of our common stock are fully-paid and non-assessable.

Transfer Restrictions. Shares of our common stock are subject to transfer restrictions. Holders of our common stock may not transfer their securities unless (a) a registration statement is in effect under the Securities Act covering the proposed transfer and such transfer is made in accordance with such registration statement or (b) the securities are transferred in a transaction exempt from the registration requirements of the Securities Act and any related requirements imposed by applicable state securities laws. In the case of any transfer permitted under clause (b), the holder must notify us in writing of the proposed transfer and furnish us with an opinion of counsel, reasonably satisfactory to us, that the transfer will not require registration under the Securities Act or any applicable state securities laws. Each certificate representing a security contains a legend referring to this restriction on transfer and any legends required by state securities laws.

Transfer Agent and Registrar

Continental Stock Transfer and Trust, located at 1 State Street 30th Floor, New York, NY 10004, is the transfer agent and registrar for our common stock.

Preferred Stock

We are authorized to issue up to 10,000,000 shares of “blank check” preferred stock, par value $0.0001 per share, with such designations, rights, and preferences as may be determined from time to time by our board of directors. Accordingly, our board of directors is empowered, without stockholder approval, to issue preferred stock with dividend, liquidation, conversion, voting, or other rights that could adversely affect the voting power or other rights of the holders of our common stock. The issuance of preferred stock could have the effect of restricting dividends on our common stock, diluting the voting power of our common stock, impairing the liquidation rights of our common stock, or delaying or preventing a change in control of our company.

If we offer a specific series of preferred stock under this prospectus, we will describe the terms of the preferred stock in the prospectus supplement for such offering and will file a copy of the certificate establishing the terms of the preferred stock with the SEC. To the extent required, this description will include:

Transfer Agent and Registrar for Preferred Stock

The transfer agent and registrar for any series or class of preferred stock will be set forth in each applicable prospectus supplement.

Anti-takeover Effects of Delaware Law and our Amended and Restated Certificate of Incorporation

Our amended and restated certificate of incorporation, our bylaws and the DGCL each contain provisions, which are summarized in the following paragraphs, which are intended to enhance the likelihood of continuity and stability in the composition of our board of directors and to discourage certain types of transactions that may involve an actual or threatened acquisition of the Company. These provisions are intended to avoid costly takeover battles, reduce the Company’s vulnerability to a hostile change of control or other unsolicited acquisition proposal, and enhance the ability of our board of directors to maximize stockholder value in connection with any unsolicited offer to acquire the Company. However, these provisions may have the effect of delaying, deterring or preventing a merger or acquisition of the Company by means of a tender offer, a proxy contest or other takeover attempt that a stockholder might consider in its best interest, including attempts that might result in a premium over the prevailing market price for the shares of common stock. Our amended and restated certificate of incorporation provides that any action required or permitted to be taken by the Company’s stockholders must be effected at a duly called annual meeting of such stockholders and may not be effected by any consent in writing by such holders unless such action is recommended by all directors of our board of directors then in office, except that holders of one or more series of Preferred Stock, if such series are expressly permitted to do so by the certificate of designation relating to such series, may take any action by written consent if such action permitted to be taken by such holders and the written consent is signed by the holders of outstanding shares of the relevant class or series having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting.

Authorized but Unissued Capital Stock

Delaware law does not require stockholder approval for any issuance of authorized shares. However, the listing requirements of Nasdaq, which apply so long as the common stock remains listed on Nasdaq, require stockholder approval of certain issuances equal to or exceeding 20% of the then outstanding voting power or then outstanding number of shares of common stock. Additional shares that may be issued in the future may be used for a variety of corporate purposes, including future public offerings, to raise additional capital or to facilitate acquisitions.

One of the effects of the existence of unissued and unreserved common stock may be to enable our board of directors to issue shares to persons friendly to current management, which issuance could render more difficult or discourage an attempt to obtain control of the Company by means of a merger, tender offer, proxy contest or otherwise and thereby protect the continuity of management and possibly deprive stockholders of opportunities to sell their shares of common stock at prices higher than prevailing market prices.

Election of Directors and Vacancies

Our amended and restated certificate of incorporation provides that our board of directors will determine the number of directors who will serve on our board of directors, subject to the rights of the holders of any series of preferred stock to elect additional directors. The exact number of directors will be fixed solely and exclusively by resolution duly adopted from time to time by our board of directors.

Our amended and restated certificate of incorporation provides that any vacancy on our board of directors, including a vacancy that results from an increase in the number of directors or a vacancy that results from the death, resignation, disqualification or removal of a director, may be filled only by a majority of the directors then in office, even if less than a quorum, subject to the rights, if any, of the holders of preferred stock.

Notwithstanding the foregoing provisions of this section, each director will serve until his successor is duly elected and qualified or until his earlier death, resignation or removal. No decrease in the number of directors constituting our board of directors will shorten the term of any incumbent director.

Business Combinations

We are subject to the provisions of Section 203 of the Delaware General Corporation Law (the “DGCL”). In general, Section 203 prohibits a publicly held Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the business combination is approved in the following prescribed manner:

Generally, for purposes of Section 203, a “business combination” includes a merger, asset or stock sale, or other transaction resulting in a financial benefit to the interested stockholder. An “interested stockholder” is a person who, together with affiliates and associates, owns or, within three years prior to the determination of interested stockholder status, owned 15% or more of a corporation’s outstanding voting securities.

Such provisions may encourage companies interested in acquiring us to negotiate in advance with our board of directors because the stockholder approval requirement would be avoided if our board of directors approves either the business combination or the transaction that results in the stockholder becoming an interested stockholder. However, such provisions also could discourage attempts that might result in a premium over the market price for the shares held by stockholders. These provisions also may make it more difficult to accomplish transactions that stockholders may otherwise deem to be in their best interests.

Quorum

Our bylaws provide that at any meeting of our board of directors, a majority of the directors then in office constitutes a quorum for all purposes.

No Cumulative Voting

Under Delaware law, the right to vote cumulatively does not exist unless the certificate of incorporation expressly authorizes cumulative voting. Our amended and restated certificate of incorporation does not authorize cumulative voting.

General Stockholder Meetings

Our amended and restated certificate of incorporation provides that special meetings of stockholders may be called only by our board of directors acting pursuant to a resolution approved by the affirmative vote of a majority of our board of directors, subject to the rights, if any, of the holders of any series of preferred stock.

Requirements for Advance Notification of Stockholder Meetings, Nominations and Proposals

Our bylaws establish advance notice procedures with respect to stockholder proposals and the nomination of candidates for election as directors, other than nominations made by or at the direction of our board of directors. For any matter to be “properly brought” before a meeting, a stockholder will have to comply with advance notice requirements and provide us with certain information. Generally, to be timely, a stockholder’s notice must be received by the Secretary at our principal executive offices not less than 90 days nor more than 120 days prior to the one-year anniversary of the date of the preceding annual meeting of stockholders (for the purposes of the first annual meeting of our stockholders following the adoption of our bylaws, a stockholder’s notice must be received by the Secretary at the Company’s principal executive offices not later than (i) 90 days prior to the date of the first annual meeting or (ii) less than 10 days following the date the first annual meeting is publicly announced). Our bylaws also specify requirements as to the form and content of a stockholder’s notice. Our bylaws allow our board of directors or a committee of our board of directors to determine whether a nomination or any business proposed to be brought before a special meeting of the stockholders was made in accordance with our bylaws. These provisions may also defer, delay or discourage a potential acquirer from conducting a solicitation of proxies to elect the acquirer’s own slate of directors or otherwise attempting to influence or obtain control of us.

Amendment Provisions

Our amended and restated certificate of incorporation and our bylaws provide that our board of directors, by the affirmative vote of a majority of our board of directors, is expressly authorized to make, alter, amend, change, add to, rescind or repeal, in whole or in part, our bylaws without a stockholder vote in any matter not inconsistent with the laws of the State of Delaware. Any amendment, alteration, rescission or repeal of our bylaws by our stockholders requires the affirmative vote of the holders of at least a majority in voting power of all the then outstanding shares of stock entitled to vote thereon, voting together as a single class.

Our amended and restated certificate of incorporation provides that it may be amended, altered, changed or repealed in accordance with the DGCL.

Exclusive Forum

Our amended and restated certificate of incorporation provides that, unless we consent to the selection of an alternative forum, any (i) derivative action or proceeding brought on our behalf, (ii) action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of the Company to us or our stockholders, creditors or other constituents, (iii) action asserting a claim against the Company or any of our directors or officers arising pursuant to, or a claim against the Company or any director or officer of the Company with respect to the interpretation or application of any provision of, the DGCL, our amended and restated certificate of incorporation or our bylaws or (iv) action asserting a claim against the Company or any director or officer of the Company governed by the internal affairs doctrine will, to the fullest extent permitted by law, be solely and exclusively brought in the Court of Chancery of the State of Delaware or, if such court does not have subject matter jurisdiction thereof, any other court located in the State of Delaware with subject matter jurisdiction. To the fullest extent permitted by law, any person or entity purchasing or otherwise acquiring or holding any interest in shares of capital stock of the Company will be deemed to have notice of and consented to the forum provisions in our amended and restated certificate of incorporation. However, it is possible that a court could find our forum selection provisions to be inapplicable or unenforceable. Although we believe this provision benefits it by providing increased consistency in the application of Delaware law in believe types of lawsuits to which it applies, the provision may have the effect of discouraging lawsuits against our directors and officers.

Our amended and restated certificate of incorporation provides that, unless we consent to the selection of an alternative forum, the federal district courts of the United States of America shall, to the fullest extent permitted by law, be the sole and exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act of 1933, as amended; provided, however, that this provision will not apply to suits brought to enforce any liability or duty created by the Securities Exchange Act of 1934, as amended, or any other claim for which the federal courts have exclusive jurisdiction.

Potential Effects of Authorized but Unissued Stock

We have shares of common stock and preferred stock available for future issuance without stockholder approval. We may utilize these additional shares for a variety of corporate purposes, including future public offerings to raise additional capital, to facilitate corporate acquisitions or payment as a dividend on the capital stock.

The existence of unissued and unreserved common stock and preferred stock may enable our board of directors to issue shares to persons friendly to current management or to issue preferred stock with terms that could render more difficult or discourage a third-party attempt to obtain control of us by means of a merger, tender offer, proxy contest or otherwise, thereby protecting the continuity of our management. In addition, the board of directors has the discretion to determine designations, rights, preferences, privileges and restrictions, including voting rights, dividend rights, conversion rights, redemption privileges and liquidation preferences of each series of preferred stock, all to the fullest extent permissible under the DGCL and subject to any limitations set forth in our amended and restated certificate of incorporation. The purpose of authorizing the board of directors to issue preferred stock and to determine the rights and preferences applicable to such preferred stock is to eliminate delays associated with a stockholder vote on specific issuances. The issuance of preferred stock, while providing desirable flexibility in connection with possible financings, acquisitions and other corporate purposes, could have the effect of making it more difficult for a third-party to acquire, or could discourage a third-party from acquiring, a majority of our outstanding voting stock.

DESCRIPTION OF STOCK WARRANTS

We summarize below some of the provisions that will apply to the warrants unless the applicable prospectus supplement provides otherwise. This summary may not contain all information that is important to you. The complete terms of the warrants will be contained in the applicable warrant certificate and warrant agreement. These documents have been or will be included or incorporated by reference as exhibits to the registration statement of which this prospectus is a part. You should read the warrant certificate and the warrant agreement. You should also read the prospectus supplement, which will contain additional information and which may update or change some of the information below.

General

We may issue warrants to purchase our debt or equity securities or securities of third parties or other rights, including rights to receive payment in cash or securities based on the value, rate or price of one or more specified commodities, currencies, securities or indices, or any combination of the foregoing. Warrants may be issued independently or together with any other securities and may be attached to, or separate from, such securities. Each series of warrants will be issued under a separate warrant agreement to be entered into between us and a bank, trust company or other financial institution, as warrant agent, or we may issue warrants directly to investors. A description of the terms and material provisions of any warrants we may issue will be set forth in the applicable prospectus supplement.

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

Transfer Agent and Registrar

The transfer agent and registrar, if any, for any warrants will be set forth in the applicable prospectus supplement.

DESCRIPTION OF DEBT SECURITIES

This prospectus describes certain general terms and provisions of debt securities that we may offer. The debt securities may be issued pursuant to, in the case of senior debt securities, a senior indenture, and in the case of subordinated debt securities, a subordinated indenture, in each case in the forms filed as exhibits to this registration statement, which we refer to as the “indentures.” The indentures will be entered into between us and a trustee to be named prior to the issuance of any debt securities, which we refer to as the “trustee.” The indentures will not limit the amount of debt securities that can be issued thereunder and will provide that the debt securities may be issued from time to time in one or more series pursuant to the terms of one or more securities resolutions or supplemental indentures creating such series.

We have summarized below the material provisions of the indentures and the debt securities or indicated which material provisions will be described in the related prospectus supplement for any offering of debt securities. These descriptions are only summaries, and you should refer to the relevant indenture for the particular offering of debt securities itself which will describe completely the terms and definitions of the offered debt securities and contain additional information about the debt securities.

Terms

When we offer to sell a particular series of debt securities, we will describe the specific terms of the securities in a prospectus supplement. The prospectus supplement will set forth the following terms, as applicable, of the debt securities offered thereby:

Debt securities of any series may be issued as registered debt securities or uncertificated debt securities, in such denominations as specified in the terms of the series.

Securities may be issued under the indentures as Discounted Debt Securities to be offered and sold at a substantial discount from the principal amount thereof. Special United States federal income tax and other considerations applicable thereto will be described in the prospectus supplement relating to such Discounted Debt Securities. “Discounted Debt Security” means a security where the amount of principal due upon acceleration is less than the stated principal amount.

We are not obligated to issue all debt securities of one series at the same time and, unless otherwise provided in the prospectus supplement, we may reopen a series, without the consent of the holders of the debt securities of that series, for the issuance of additional debt securities of that series. Additional debt securities of a particular series will have the same terms and conditions as outstanding debt securities of such series, except for the date of original issuance and the offering price, and will be consolidated with, and form a single series with, such outstanding debt securities.

Ranking

The senior debt securities will rank equally with all of our other senior and unsubordinated debt. Our secured debt, if any, will be effectively senior to the senior debt securities to the extent of the value of the assets securing such debt. The subordinated debt securities will be subordinate and junior in right of payment to all of our present and future senior indebtedness to the extent and in the manner described in the prospectus supplement and as set forth in the board resolution, officer’s certificate or supplemental indenture relating to such offering.

We have only a stockholder’s claim on the assets of our subsidiaries. This stockholder’s claim is junior to the claims that creditors of our subsidiaries have against our subsidiaries. Holders of our debt securities will be our creditors and not creditors of any of our subsidiaries. As a result, all the existing and future liabilities of our subsidiaries, including any claims of their creditors, will effectively be senior to the debt securities with respect to the assets of our subsidiaries. In addition, to the extent that we issue any secured debt, the debt securities will be effectively subordinated to such secured debt to the extent of the value of the assets securing such secured debt.

The debt securities will be obligations exclusively of Reviva Pharmaceuticals Holdings, Inc. To the extent that our ability to service our debt, including the debt securities, may be dependent upon the earnings of our subsidiaries, our ability to do so will be dependent on the ability of our subsidiaries to distribute those earnings to us as dividends, loans or other payments.

Certain Covenants

Any covenants that may apply to a particular series of debt securities will be described in the prospectus supplement relating thereto.

Successor Obligor

The indentures provide that, unless otherwise specified in the securities resolution or supplemental indenture establishing a series of debt securities, we shall not consolidate with or merge into, or transfer all or substantially all of our assets to, any person in any transaction in which we are not the survivor, unless:

In such event, the successor will be substituted for us, and thereafter all of our obligations under the relevant indenture, the debt securities and any coupons will terminate.

The indentures provide that these limitations shall not apply if our board of directors makes a good faith determination that the principal purpose of the transaction is to change our state of incorporation.

Exchange of Debt Securities

Registered debt securities may be exchanged for an equal aggregate principal amount of registered debt securities of the same series and date of maturity in such authorized denominations as may be requested upon surrender of the registered debt securities at an agency of the Company maintained for such purpose and upon fulfillment of all other requirements of such agent.

Default and Remedies

Unless the securities resolution or supplemental indenture establishing the series otherwise provides (in which event the prospectus supplement will so state), an “Event of Default” with respect to a series of debt securities will occur if:

The term “Bankruptcy Law” means Title 11 of the United States Code or any similar Federal or State law for the relief of debtors. The term “Custodian” means any receiver, trustee, assignee, liquidator or a similar official under any Bankruptcy Law.

“Default” means any event which is, or after notice or passage of time would be, an Event of Default. A Default under subparagraph (3) above is not an Event of Default until the trustee or the holders of at least 25% in principal amount of the series notify us of the Default and we do not cure the Default within the time specified after receipt of the notice.

The trustee may require indemnity satisfactory to it before it enforces the indentures or the debt securities of the series. Subject to certain limitations, holders of a majority in principal amount of the debt securities of the series may direct the trustee in its exercise of any trust or power with respect to such series. Except in the case of Default in payment on a series, the trustee may withhold from securityholders of such series notice of any continuing Default if the trustee determines that withholding notice is in the interest of such securityholders. We are required to furnish the trustee annually a brief certificate as to our compliance with all conditions and covenants under the indentures.

The indentures do not have cross-default provisions. Thus, a default by us on any other debt, including any other series of debt securities, would not constitute an Event of Default.

Amendments and Waivers

The indentures and the debt securities or any coupons of the series may be amended, and any Default may be waived as follows:

Unless the securities resolution or supplemental indenture otherwise provides (in which event the applicable prospectus supplement will so state), the debt securities and the indentures may be amended with the consent of the holders of a majority in principal amount of the debt securities of all series affected voting as one class. Unless the securities resolution or supplemental indenture otherwise provides (in which event the applicable prospectus supplement will so state), a Default other than a Default in payment on a particular series may be waived with the consent of the holders of a majority in principal amount of the debt securities of the series. However, without the consent of each securityholder affected, no amendment or waiver may:

Without the consent of any securityholder, the indentures or the debt securities may be amended to:

Conversion Rights

Any securities resolution or supplemental indenture establishing a series of debt securities may provide that the debt securities of such series will be convertible at the option of the holders thereof into or for our common stock or other equity or debt instruments. The securities resolution or supplemental indenture may establish, among other things, (1) the number or amount of shares of common stock or other equity or debt instruments for which $1,000 aggregate principal amount of the debt securities of the series is convertible, as may be adjusted pursuant to the terms of the relevant indenture and the securities resolution; and (2) provisions for adjustments to the conversion rate and limitations upon exercise of the conversion right. The indentures provide that we will not be required to make an adjustment in the conversion rate unless the adjustment would require a cumulative change of at least 1% in the conversion rate. However, we will carry forward any adjustments that are less than 1% of the conversion rate and take them into account in any subsequent adjustment of the conversion rate.

Legal Defeasance and Covenant Defeasance

Debt securities of a series may be defeased in accordance with their terms and, unless the securities resolution or supplemental indenture establishing the terms of the series otherwise provides, as set forth below. We at any time may terminate as to a series all of our obligations (except for certain obligations, including obligations with respect to the defeasance trust and obligations to register the transfer or exchange of a debt security, to replace destroyed, lost or stolen debt securities and coupons and to maintain paying agencies in respect of the debt securities) with respect to the debt securities of the series and any related coupons and the relevant indenture, which we refer to as legal defeasance. We at any time may terminate as to a series our obligations with respect to any restrictive covenants which may be applicable to a particular series, which we refer to as covenant defeasance.

We may exercise our legal defeasance option notwithstanding our prior exercise of our covenant defeasance option. If we exercise our legal defeasance option, a series may not be accelerated because of an Event of Default. If we exercise our covenant defeasance option, a series may not be accelerated by reference to any covenant which may be applicable to a series.

To exercise either defeasance option as to a series, we must (1) irrevocably deposit in trust with the trustee (or another trustee) money or U.S. Government Obligations (as defined below), deliver a certificate from a nationally recognized firm of independent accountants expressing their opinion that the payments of principal and interest when due on the deposited U.S. Government Obligations, without reinvestment, plus any deposited money without investment will provide cash at such times and in such amounts as will be sufficient to pay the principal and interest when due on all debt securities of such series to maturity or redemption, as the case may be; and (2) comply with certain other conditions. In particular, we must obtain an opinion of tax counsel that the defeasance will not result in recognition of any gain or loss to holders for federal income tax purposes.

“U.S. Government Obligations” means direct obligations of the United States or any agency or instrumentality of the United States, the payment of which is unconditionally guaranteed by the United States, which, in either case, have the full faith and credit of the United States pledged for payment and which are not callable at the issuer’s option, or certificates representing an ownership interest in such obligations.

Regarding the Trustee

Unless otherwise indicated in a prospectus supplement, the trustee will also act as depository of funds, transfer agent, paying agent and conversion agent, as applicable, with respect to the debt securities. In certain circumstances, we or the securityholders may remove the trustee as the trustee under a given indenture. The indenture trustee may also provide additional unrelated services to us as a depository of funds, registrar, trustee and similar services.

Governing Law

The indentures and the debt securities will be governed by New York law, except to the extent that the Trust Indenture Act of 1939 is applicable.

DESCRIPTION OF SUBSCRIPTION RIGHTS

We may issue subscription rights to purchase our equity or debt securities. These subscription rights may be offered independently or together with any other security offered hereby and may or may not be transferable by the stockholder receiving the subscription rights in such offering. In connection with any offering of subscription rights, we may enter into a standby arrangement with one or more underwriters or other purchasers pursuant to which the underwriters or other purchasers may be required to purchase any securities remaining unsubscribed for after such offering.

The prospectus supplement relating to any subscription rights we offer, if any, will, to the extent applicable, include specific terms relating to the offering, including some or all of the following:

DESCRIPTION OF UNITS

We may issue units comprised of one or more of the other 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 (but, to the extent convertible securities are included in the units, the holder of the units will be deemed the holder of the convertible securities and not the holder of the underlying securities). The unit agreement under which a unit is issued, if any, may provide that the securities included in the unit may not be held or transferred separately, at any time or at any time before a specified date. The applicable prospectus supplement may describe:

This summary of certain general terms of units and any summary description of units in the applicable prospectus supplement do not purport to be complete and are qualified in their entirety by reference to all provisions of the applicable unit agreement and, if applicable, collateral arrangements and depositary arrangements relating to such units. The forms of the unit agreements and other documents relating to a particular issue of units will be filed with the SEC each time we issue units, and you should read those documents for provisions that may be important to you.

FORMS OF SECURITIES

Each debt security and, to the extent applicable, warrant, subscription right and unit, will be represented either by a certificate issued in definitive form to a particular investor or by one or more global securities representing the entire issuance of securities. Certificated securities in definitive form and global securities will be issued in registered form. Definitive securities name you or your nominee as the owner of the security, and in order to transfer or exchange these securities or to receive payments other than interest or other interim payments, you or your nominee must physically deliver the securities to the trustee, registrar, paying agent or other agent, as applicable. Global securities name a depositary or its nominee as the owner of the debt securities or warrants represented by these global securities. The depositary maintains a computerized system that will reflect each investor’s beneficial ownership of the securities through an account maintained by the investor with its broker/dealer, bank, trust company or other representative, as we explain more fully below.

Global Securities

Registered Global Securities. We may issue the registered debt securities and, to the extent applicable, warrants, subscription rights and units in the form of one or more fully registered global securities that will be deposited with a depositary or its nominee identified in the applicable prospectus supplement and registered in the name of that depositary or nominee. In those cases, one or more registered global securities will be issued in a denomination or aggregate denominations equal to the portion of the aggregate principal or face amount of the securities to be represented by registered global securities. Unless and until it is exchanged in whole for securities in definitive registered form, a registered global security may not be transferred except as a whole by and among the depositary for the registered global security, the nominees of the depositary or any successors of the depositary or those nominees.

If not described below, any specific terms of the depositary arrangement with respect to any securities to be represented by a registered global security will be described in the prospectus supplement relating to those securities. We anticipate that the following provisions will apply to all depositary arrangements.

Ownership of beneficial interests in a registered global security will be limited to persons, called participants, that have accounts with the depositary or persons that may hold interests through participants. Upon the issuance of a registered global security, the depositary will credit, on its book-entry registration and transfer system, the participants’ accounts with the respective principal or face amounts of the securities beneficially owned by the participants. Any dealers, underwriters or agents participating in the distribution of the securities will designate the accounts to be credited. Ownership of beneficial interests in a registered global security will be shown on, and the transfer of ownership interests will be effected only through, records maintained by the depositary, with respect to interests of participants, and on the records of participants, with respect to interests of persons holding through participants. The laws of some states may require that some purchasers of securities take physical delivery of these securities in definitive form. These laws may impair your ability to own, transfer or pledge beneficial interests in registered global securities.

So long as the depositary, or its nominee, is the registered owner of a registered global security, that depositary or its nominee, as the case may be, will be considered the sole owner or holder of the securities represented by the registered global security for all purposes under the applicable indenture or warrant agreement. Except as described below, owners of beneficial interests in a registered global security will not be entitled to have the securities represented by the registered global security registered in their names, will not receive or be entitled to receive physical delivery of the securities in definitive form and will not be considered the owners or holders of the securities under the applicable indenture or warrant agreement. Accordingly, each person owning a beneficial interest in a registered global security must rely on the procedures of the depositary for that registered global security and, if that person is not a participant, on the procedures of the participant through which the person owns its interest, to exercise any rights of a holder under the applicable indenture or warrant agreement. We understand that under existing industry practices, if we request any action of holders or if an owner of a beneficial interest in a registered global security desires to give or take any action that a holder is entitled to give or take under the applicable indenture or warrant agreement, the depositary for the registered global security would authorize the participants holding the relevant beneficial interests to give or take that action, and the participants would authorize beneficial owners owning through them to give or take that action or would otherwise act upon the instructions of beneficial owners holding through them.

Principal, premium, if any, and interest payments on debt securities and any payments to holders with respect to warrants represented by a registered global security registered in the name of a depositary or its nominee will be made to the depositary or its nominee, as the case may be, as the registered owner of the registered global security. None of the Company, the trustees, the warrant agents or any other agent of the Company, agent of the trustees or agent of the warrant will have any responsibility or liability for any aspect of the records relating to payments made on account of beneficial ownership interests in the registered global security or for maintaining, supervising or reviewing any records relating to those beneficial ownership interests.

We expect that the depositary for any of the securities represented by a registered global security, upon receipt of any payment of principal, premium, interest or other distribution of underlying securities or other property to holders on that registered global security, will immediately credit participants’ accounts in amounts proportionate to their respective beneficial interests in that registered global security as shown on the records of the depositary. We also expect that payments by participants to owners of beneficial interests in a registered global security held through participants will be governed by standing customer instructions and customary practices, as is now the case with the securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of those participants.

If the depositary for any of these securities represented by a registered global security is at any time unwilling or unable to continue as depositary or ceases to be a clearing agency registered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and a successor depositary registered as a clearing agency under the Exchange Act is not appointed by us within 90 days, we will issue securities in definitive form in exchange for the registered global security that had been held by the depositary. Any securities issued in definitive form in exchange for a registered global security will be registered in the name or names that the depositary gives to the relevant trustee or warrant agent or other relevant agent of ours or theirs. It is expected that the depositary’s instructions will be based upon directions received by the depositary from participants with respect to ownership of beneficial interests in the registered global security that had been held by the depositary.

PLAN OF DISTRIBUTION

Initial Offering and Sale of Securities

Unless otherwise set forth in a prospectus supplement accompanying this prospectus, we may sell the securities being offered hereby, from time to time, by one or more of the following methods:

Offerings of securities covered by this prospectus also may be made into an existing trading market for those securities in transactions at other than a fixed price, either:

Those at-the-market offerings, if any, will be conducted by underwriters acting as principal or agent of the Company, who may also be third-party sellers of securities as described above. The prospectus supplement with respect to the offered securities will set forth the terms of the offering of the offered securities, including:

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

Each prospectus supplement will set forth the manner and terms of an offering of securities including:

In addition, we may enter into derivative or hedging transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. The applicable prospectus supplement may indicate, in connection with such a transaction, that the third parties may sell securities covered by and pursuant to this prospectus and an applicable prospectus supplement. If so, the third party may use securities pledged by us or borrowed from us or others to settle such sales and may use securities received from us to close out any related short positions. We may also loan or pledge securities covered by this prospectus and an applicable prospectus supplement to third parties, who may sell the loaned securities or, in an event of default in the case of a pledge, sell the pledged securities pursuant to this prospectus and the applicable prospectus supplement.

Sales Through Underwriters

If underwriters are used in the sale of some or all of the securities covered by this prospectus, the underwriters will acquire the securities for their own account. The underwriters may resell the securities, either directly to the public or to securities dealers, at various times in one or more transactions, including negotiated 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 certain conditions. Unless indicated otherwise in a prospectus supplement, the underwriters will be obligated to purchase all the securities of the series offered if any of the securities are purchased.

Any public offering price and any concessions allowed or reallowed to dealers may be changed intermittently.

Sales Through Agents

Unless otherwise indicated in the applicable prospectus supplement, when securities are sold through an agent, the designated agent will agree, for the period of its appointment as agent, to use specified efforts to sell the securities for our account and will receive commissions from us as will be set forth in the applicable prospectus supplement.

Securities bought in accordance with a redemption or repayment under their terms also may be offered and sold, if so indicated in the applicable prospectus supplement, in connection with a remarketing by one or more firms acting as principals for their own accounts or as agents for us. Any remarketing firm will be identified and the terms of its agreement, if any, with us and its compensation will be described in the prospectus supplement. Remarketing firms may be deemed to be underwriters in connection with the securities remarketed by them.

If so indicated in the applicable prospectus supplement, we may authorize agents, underwriters or dealers to solicit offers by certain specified institutions to purchase securities at a price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a future date specified in the prospectus supplement. These contracts will be subject only to those conditions set forth in the applicable prospectus supplement, and the prospectus supplement will set forth the commissions payable for solicitation of these contracts.

Direct Sales

We may also sell offered securities directly to institutional investors or others. In this case, no underwriters or agents would be involved. The terms of such sales will be described in the applicable prospectus supplement.

General Information

Broker-dealers, agents or underwriters may receive compensation in the form of discounts, concessions or commissions from us and/or the purchasers of securities for whom such broker-dealers, agents or underwriters may act as agents or to whom they sell as principal, or both. This compensation to a particular broker-dealer might be in excess of customary commissions.

Underwriters, dealers and agents that participate in any distribution of the offered securities may be deemed “underwriters” within the meaning of the Securities Act of 1933, as amended (the “Securities Act”), so any discounts or commissions they receive in connection with the distribution may be deemed to be underwriting compensation. Those underwriters and agents may be entitled, under their agreements with us, to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, or to contribution by us to payments that they may be required to make in respect of those civil liabilities. Certain of those underwriters or agents may be customers of, engage in transactions with, or perform services for, us or our affiliates in the ordinary course of business. We will identify any underwriters or agents, and describe their compensation, in a prospectus supplement. Any institutional investors or others that purchase offered securities directly, and then resell the securities, may be deemed to be underwriters, and any discounts or commissions received by them from us and any profit on the resale of the securities by them may be deemed to be underwriting discounts and commissions under the Securities Act.

We will file a supplement to this prospectus, if required, pursuant to Rule 424(b) under the Securities Act, if we enter into any material arrangement with a broker, dealer, agent or underwriter for the sale of securities through a block trade, special offering, exchange distribution or secondary distribution or a purchase by a broker or dealer. Such prospectus supplement will disclose:

In order to facilitate the offering of certain securities under this prospectus or an applicable prospectus supplement, certain persons participating in the offering of those securities may engage in transactions that stabilize, maintain or otherwise affect the price of those securities during and after the offering of those securities. Specifically, if the applicable prospectus supplement permits, the underwriters of those securities may over-allot or otherwise create a short position in those securities for their own account by selling more of those securities than have been sold to them by us and may elect to cover any such short position by purchasing those securities in the open market.

In addition, the underwriters may stabilize or maintain the price of those securities by bidding for or purchasing those securities in the open market and may impose penalty bids, under which selling concessions allowed to syndicate members or other broker-dealers participating in the offering are reclaimed if securities previously distributed in the offering are repurchased in connection with stabilization transactions or otherwise. The effect of these transactions may be to stabilize or maintain the market price of the securities at a level above that which might otherwise prevail in the open market. The imposition of a penalty bid may also affect the price of securities to the extent that it discourages resales of the securities. No representation is made as to the magnitude or effect of any such stabilization or other transactions. Such transactions, if commenced, may be discontinued at any time.

In order to comply with the securities laws of certain states, if applicable, the securities must be sold in such jurisdictions only through registered or licensed brokers or dealers. In addition, in certain states the securities may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

Rule 15c6-1 under the Exchange Act generally requires that trades in the secondary market settle in two business days, unless the parties to any such trade expressly agree otherwise. Your prospectus supplement may provide that the original issue date for your securities may be more than two scheduled business days after the trade date for your securities. Accordingly, in such a case, if you wish to trade securities on any date prior to the second business day before the original issue date for your securities, you will be required, by virtue of the fact that your securities initially are expected to settle in more than two scheduled business days after the trade date for your securities, to make alternative settlement arrangements to prevent a failed settlement.

This prospectus, any applicable prospectus supplement and any applicable pricing supplement in electronic format may be made available on the Internet sites of, or through other online services maintained by, us and/or one or more of the agents and/or dealers participating in an offering of securities, or by their affiliates. In those cases, prospective investors may be able to view offering terms online and, depending upon the particular agent or dealer, prospective investors may be allowed to place orders online.

Other than this prospectus, any applicable prospectus supplement and any applicable pricing supplement in electronic format, the information on our website or the website of any agent or dealer, and any information contained in any other website maintained by any agent or dealer:

There can be no assurance that we will sell all or any of the securities offered by this prospectus.

This prospectus may also be used in connection with any issuance of common stock or preferred stock upon exercise of a warrant if such issuance is not exempt from the registration requirements of the Securities Act.

In addition, we may issue the securities as a dividend or distribution or in a subscription rights offering to our existing securityholders. In some cases, we or dealers acting with us or on our behalf may also purchase securities and reoffer them to the public by one or more of the methods described above. This prospectus may be used in connection with any offering of our securities through any of these methods or other methods described in the applicable prospectus supplement.

LEGAL MATTERS

Unless otherwise indicated in the applicable prospectus supplement, the validity of the securities offered hereby will be passed upon for us by Lowenstein Sandler LLP, New York, New York. If the validity of the securities offered hereby in connection with offerings made pursuant to this prospectus are passed upon by counsel for the underwriters, dealers or agents, if any, such counsel will be named in the prospectus supplement relating to such offering.
