PROSPECTUS SUPPLEMENT

(To Prospectus dated March 24, 2023)

Up to $64,910,161 Common Stock

We have entered into a Sales Agreement, dated November 6, 2025 (the "Sales Agreement"), with Clear Street LLC ("Clear Street") and President Street Global, LLC ("President Street" and together with Clear Street, the "Sales Agents"), relating to shares of our common stock, par value $0.0001 per share (the "Common Stock"), offered by this prospectus supplement and the accompanying prospectus. In accordance with the terms of the Sales Agreement, we may offer and sell shares of our Common Stock having a maximum aggregate offering price of up to $64,910,161 from time to time through the Sales Agents.

Sales of shares of our Common Stock, if any, made through the Sales Agents, or directly to the Sales Agents, as principals, as contemplated in this prospectus supplement and the accompanying prospectus, may be made in negotiated transactions or transactions that are deemed to be "at the market offerings" as defined in Rule 415(a)(4) promulgated under the Securities Act of 1933, as amended, (the "Securities Act"). The Sales Agents are not required to sell any specific amount of shares of Common Stock, but will act as our sales agent using commercially reasonable efforts consistent with their normal trading and sales practices and applicable law and regulations, on mutually agreed terms between the Sales Agents and us. There is no arrangement for funds to be received in any escrow, trust or similar arrangement. The compensation to the Sales Agents for sales of Common Stock sold pursuant to the Sales Agreement will be in an amount up to 3.0% of the gross proceeds of any shares of Common Stock sold under the Sales Agreement. In connection with the sale of the Common Stock on our behalf, the Sales Agents may be deemed to be "underwriters" within the meaning of the Securities Act, and the compensation of the Sales Agents may be deemed to be underwriting commissions or discounts. See "Plan of Distribution" beginning on page S-17 for additional information regarding the compensation to be paid to the Sales Agents. We have also agreed to provide indemnification and contribution to the Sales Agents with respect to certain liabilities, including liabilities under the Securities Act or the Securities Exchange Act of 1934, as amended, (the "Exchange Act").

Under the terms of the Sales Agreement, we also may sell our Common Stock to one or both of the Sales Agents, as principals for their own accounts, at a price agreed upon at the time of sale. If we sell our Common Stock to one or both of the Sales Agents, as principals, we will enter into a separate agreement with the applicable Sales Agent(s), setting forth the terms of such transaction, and we will describe the agreement in a separate prospectus supplement or pricing supplement.

Our Common Stock is listed on The Nasdaq Capital Market under the symbol "THAR." On November 5, 2025, the last reported sales price of our Common Stock on The Nasdaq Capital Market was $3.99 per share.

As of the date of this prospectus supplement, we have sold securities with a value of $10,089,839 during the prior 12 calendar month period that ends on, and includes, the date of this prospectus supplement.

We are an "emerging growth company" and a "smaller reporting company" as those terms are defined under the federal securities laws and, as such, have elected to comply with certain reduced public company reporting requirements.

Investing in our Common Stock involves a high degree of risk. Before making any decision to invest in our securities, you should carefully consider the information disclosed in this this prospectus supplement and the accompanying prospectus, including the information under "Risk Factors" beginning on page S-9 of this prospectus supplement and page 7 of the accompanying prospectus, as well as the information, including the risk factors contained or incorporated by reference to this prospectus supplement and the accompanying prospectus as described under the heading "Where You Can Find More Information."

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or passed upon the adequacy or accuracy of this prospectus supplement and the accompanying prospectus. Any representation to the contrary is a criminal offense.

This prospectus and any prospectus supplement is an offer to sell only the securities offered hereby, but only under circumstances and in jurisdictions where it is lawful to do so. You should assume that the information contained in this prospectus and in any prospectus supplement is accurate only as of their respective dates and that any information we have incorporated by reference is accurate only as of the date of the document incorporated by reference, regardless of the time of delivery of this prospectus or any prospective supplement or any sale of securities. The registration statement, including the exhibits and the documents incorporated herein by reference, can be read on the website of the Securities and Exchange Commission, or "SEC," or on our corporate website at www.tharimmune.com as set forth in this prospectus under the heading "Available Information."

This prospectus supplement is not an offer to sell or a solicitation of an offer to buy securities in any jurisdiction in which such offer or solicitation is illegal.

ABOUT THIS PROSPECTUS SUPPLEMENT

All references to the terms the "Company," "we," "us" or "our" in this prospectus supplement refer to Tharimmune, Inc., a Delaware corporation, unless the context requires otherwise.

This prospectus supplement and the accompanying base prospectus are part of a registration statement that we filed with the Securities and Exchange Commission (the "SEC") on Form S-3 (File No. 333-270684) utilizing a "shelf" registration process. Each time we conduct an offering to sell securities under the accompanying base prospectus we will provide a prospectus supplement that will contain specific information about the terms of that offering, including the price, the amount of securities being offered, and the plan of distribution. The shelf registration statement was initially filed with the SEC on March 17, 2023, and was declared effective on March 24, 2023. This document is in two parts. This first part is this prospectus supplement, which describes the specific terms of the Common Stock we are offering and also adds to and updates information contained in the accompanying base prospectus. The accompanying base prospectus provides general information about us and our securities, some of which, such as the section entitled "Plan of Distribution," may not apply to this offering. This prospectus supplement and the accompanying base prospectus are an offer to sell only the securities offered hereby, but only under circumstances and in jurisdictions where it is lawful to do so. We are not making offers to sell or solicitations to buy our securities in any jurisdiction in which an offer or solicitation is not authorized or in which the person making that offer or solicitation is not qualified to do so or to anyone to whom it is unlawful to make an offer or solicitation.

If information in this prospectus supplement is inconsistent with the accompanying base prospectus or the information incorporated by reference with an earlier date, you should rely on this prospectus supplement; provided that if any statement in one of these documents is inconsistent with a statement in another document having a later date, the statement in the document having the later date modifies or supersedes the earlier statement. This prospectus supplement, together with the accompanying base prospectus and the documents incorporated by reference into this prospectus supplement and the accompanying base prospectus, include all material information relating to this offering. You should assume that the information appearing in this prospectus supplement, the accompanying base prospectus and the documents incorporated by reference in this prospectus supplement and the accompanying base prospectus is accurate only as of the respective dates of those documents. Our business, financial condition, results of operations and prospects may have changed since those dates. You should carefully read this prospectus supplement, the accompanying base prospectus and the information and documents incorporated by reference herein and therein before making an investment decision. See "Where You Can Find More Information" in this prospectus supplement and in the accompanying base prospectus.

Neither we nor the Sales Agents have authorized anyone to provide you with different information, and neither we nor the Sales Agents take responsibility for any other information others may give you. When you make a decision about whether to invest in our securities, you should not rely upon any information other than the information contained in or incorporated by reference into this prospectus supplement, the accompanying base prospectus or in any free writing prospectus that we may authorize to be delivered or made available to you. Neither the delivery of this prospectus supplement and the accompanying base prospectus nor the sale of our securities means that the information contained in this prospectus supplement, the accompanying base prospectus or any free writing prospectus is correct after the date of the respective dates of such documents.

Neither we nor the Sales Agents are making an offer to sell these securities in any jurisdiction where the offer or sale is not permitted. We have not, and the Sales Agents have not, taken any action that would permit this offering or possession or distribution of this prospectus supplement or the accompanying base prospectus in any jurisdiction where action for that purpose is required, other than in the United States. Persons outside the United States who come into possession of this prospectus supplement or the accompanying base prospectus must inform themselves about, and observe any restrictions relating to, the offering of the securities covered hereby and the distribution of this prospectus supplement and the accompanying base prospectus outside the United States.

This prospectus supplement and the accompanying base prospectus contain summaries of certain provisions contained in some of the documents described herein, but reference is made to the actual documents for complete information. All of the summaries are qualified in their entirety by the full text of the actual documents, some of which have been filed or will be filed with the SEC and incorporated by reference herein. See "Where You Can Find More Information" in this prospectus supplement. We further note that the representations, warranties and covenants made by us in any agreement that is filed as an exhibit to any document that is incorporated by reference into this prospectus supplement or the accompanying base prospectus were made solely for the benefit of the parties to such agreement, including, in some cases, for the purpose of allocating risk among the parties to such agreements, and should not be deemed to be a representation, warranty or covenant to you. Moreover, such representations, warranties or covenants were accurate only as of the date when made. Accordingly, such representations, warranties and covenants should not be relied on as accurately representing the current state of our affairs.

This prospectus supplement and the accompanying base prospectus, including information Incorporated by reference herein. contain and incorporate by reference certain market data and industry statistics and forecasts that are based on studies sponsored by us, independent industry publications and other publicly available information. Although we believe these sources are reliable, estimates as they relate to projections involve numerous assumptions, are subject to risks and uncertainties, and are subject to change based on various factors, including those discussed under "Risk Factors" in this prospectus supplement and the accompanying base prospectus and under similar headings in the documents incorporated by reference herein and therein. Accordingly, investors should not place undue reliance on this information.

CAUTIONARY NOTE CONCERNING FORWARD-LOOKING STATEMENTS

This prospectus supplement, including the documents that we incorporate by reference, contain forward-looking statements within the meaning of Section 27A of the Securities Act, and Section 21E of the Exchange Act. All statements other than statements of historical fact contained in this prospectus, including statements regarding future events, our future financial performance, business strategy and plans and objectives of management for future operations, are forward-looking statements. We have attempted to identify forward-looking statements by terminology including "anticipates," "believes," "can," "continue," "could," "estimates," "expects," "intends," "may," "plans," "potential," "predicts," "should," or "will," or the negative of these terms or other comparable terminology. Although we do not make forward looking statements unless we believe we have a reasonable basis for doing so, we cannot guarantee their accuracy. These statements are only predictions and involve known and unknown risks, uncertainties and other factors, including the risks outlined under "Risk Factors" or elsewhere in this prospectus, which may cause our or our industry's actual results, levels of activity, performance or achievements expressed or implied by these forward-looking statements.

The forward-looking statements included or incorporated by reference in this prospectus supplement include but are not limited to statements relating to: the adoption of a digital asset treasury, our future growth and operational progress, our ability to compete effectively, our future expenses and cash flow, our ability to become profitable, our future financing arrangements, any future stock price, fluctuations in the market price of Canton Coin, our ability to build commercial infrastructure, failure to realize the anticipated benefits of the digital asset treasury strategy; changes in business, market, financial, political and regulatory conditions; risks relating to our operations and business, including the highly volatile nature of the price of Canton Coin and other cryptocurrencies; the risk that the price of the our Common Stock may be highly correlated to the price of the digital assets that we hold.

Forward-looking statements are based on information available at the time they are made and/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 what is expressed in or suggested by the forward-looking statements.

Forward-looking statements speak only as of the date they are made. You should not put undue reliance on any forward-looking statements. You should carefully read this prospectus supplement, the accompanying prospectus, any future prospectus supplement and any related free writing prospectus and with the understanding that our actual future results may materially differ from what we expect. Except as required by law, we assume no obligation to update forward-looking statements to reflect actual results, changes in assumptions, or changes in other factors affecting forward-looking information, except to the extent required by applicable securities laws. If we do update one or more forward-looking statements, no inference should be drawn that we will make additional updates with respect to those or other forward-looking statements.

Neither the Sales Agents nor any of their respective affiliates have made or make any representation or warranty, express or implied, as to the accuracy or completeness of the information contained in this prospectus supplement.

RISK FACTORS

Investing in our Common Stock involves a high degree of risk. Before making an investment decision, you should carefully consider the risks described in this prospectus supplement, together with all of the other information incorporated by reference into this prospectus supplement and the accompanying prospectus, including the risks described in our most recent Annual Report on Form 10-K and most recent Quarterly 10-Q, as well as any amendments thereto reflected in subsequent filings with the SEC, including our audited consolidated financial statements and corresponding management's discussion and analysis. The risks mentioned below are presented as of the date of this prospectus supplement and we expect that these will be updated from time to time in our periodic and current reports filed with or furnished to the SEC, as applicable, which are incorporated herein by reference. Please refer to these subsequent reports for additional information relating to the risks associated with investing in our securities.

Our business, financial condition or results of operations could be materially adversely affected by any of these risks. Additional risks not presently known to us or that we currently deem immaterial may also impair our business operations. The trading price of our Common Stock could decline due to any of these risks, and you may lose all or part of your investment. This prospectus supplement, the accompanying prospectus and the incorporated documents also contain forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including the risks mentioned below. Forward-looking statements included in this prospectus supplement are based on information available to us on the date hereof, and all forward-looking statements in documents incorporated by reference are based on information available to us as of the date of each such document. We are under no obligation to update or alter such forward-looking statements whether as a result of new information, future events or otherwise, other than as required by applicable securities legislation.

Risks Relating to This Offering

Sales of our Common Stock by stockholders may have an adverse effect on the then prevailing market price of our Common Stock.

We may issue shares of our Common Stock from time to time in connection with this offering. The issuance from time to time of these new shares of Common Stock, or our ability to issue new shares of Common Stock in this offering, could cause the market price of our Common Stock to decline and could impair our ability to raise capital through the sale of additional equity securities. We cannot predict the effect that future sales of our Common Stock or other equity or equity-related securities would have on the market price of our Common Stock.

The Common Stock offered hereby will be sold in "at the market" offerings, and investors who buy shares at different times will likely pay different prices.

Investors who purchase shares in this offering at different times will likely pay different prices and so may experience different outcomes in their investment results. We will have discretion, subject to market demand, to vary the timing, prices, and numbers of shares sold, and there is no minimum or maximum sales price. Investors may experience a decline in the value of their shares as a result of share sales made at prices lower than the prices they paid.

Management will have broad discretion as to the use of the net proceeds from this offering and our existing cash and may not use the proceeds effectively.

We intend to use the net proceeds from the sale of securities by us in this offering expect to use the net proceeds from this offering primarily to acquire to the purchasing, long-term holding, and staking of Canton Coin, including operating Canton Coin validators to earn rewards and contribute to the Canton Network's security and decentralization and reinvesting staking yields to further expand our Canton Coin holdings and strengthen our engagement within the Canton Coin ecosystem. We also intend to use the proceeds from this offering for working capital needs and general corporate expenses, which may include funding acquisitions or investments in businesses, products or technologies that are complementary to our own. Our management will have broad discretion as to the application of the net proceeds from this offering and could use them for purposes other than those contemplated at the time of this offering, as described below in the section entitled "Use of Proceeds," or in ways that do not necessarily improve our operating results or enhance the value of our Common Stock. Our stockholders may not agree with the manner in which our management chooses to allocate and spend the net proceeds. Our failure to use these funds effectively could have a material adverse effect on our business and could cause the price of our securities to decline.

Investors in this offering will suffer immediate and substantial dilution in the net tangible book value per Common Stock.

A purchaser of securities in this offering will experience immediate and substantial dilution.

We may require additional funding through further issuances of our Common Stock or other securities, which may negatively affect the market price of our Common Stock.

To operate our business, we may need to raise additional capital through sales of our Common Stock, securities exercisable for or convertible into our Common Stock or debt securities pursuant to which interest and/or principal

payments may be satisfied through the issuance of our Common Stock. Future sales of such securities or our Common Stock could adversely affect the prevailing market price of our Common Stock and our ability to raise capital in the future, and may cause you to incur additional dilution.

We do not intend to pay dividends on our Common Stock for the foreseeable future so any returns will depend on appreciation in the price of our Common Stock.

We have never declared or paid any cash dividends on our Common Stock. We currently anticipate that we will retain future earnings, if any, for the development, operation and expansion of our business and do not anticipate declaring or paying any cash dividends for the foreseeable future. Any return to stockholders will, therefore, be limited to the appreciation of their respective shares. There is no guarantee that our Common Stock will appreciate in value or maintain the price at which you purchased them.

An active trading market for our Common Stock may not be sustained and investors may not be able to resell their shares at or above the price at which they purchased them.

An active trading market for our shares of Common Stock may not be sustained. In the absence of an active trading market for our Common Stock, investors may not be able to sell their Common Stock at or above the price they paid or at the time that they would like to sell. In addition, an inactive market could impair our ability to raise capital by selling shares and could impair our ability to acquire other companies or technologies by using our shares as consideration, which, in turn, could harm our business.

Risks Related to Managing Our Business and Operations

We may be subject to regulatory developments related to crypto assets and crypto asset markets, which could adversely affect our business, financial condition, and results of operations.

As Canton Coin and other digital assets are relatively novel and the application of state and federal securities laws and other laws and regulations to digital assets is unclear in certain respects, it is possible that regulators in the United States or foreign countries may interpret or apply existing laws and regulations in a manner that adversely affects the price of Canton Coin. The U.S. federal government, states, regulatory agencies, and foreign countries may also enact new laws and regulations, or pursue regulatory, legislative, enforcement or judicial actions, that could materially impact the price of Canton Coin or the ability of individuals or institutions such as us to own or transfer Canton Coin.

If Canton Coin is determined to constitute a security for purposes of the federal securities laws, the additional regulatory restrictions imposed by such a determination could adversely affect the market price of Canton Coin and in turn adversely affect the market price of our Common Stock. Moreover, the risks of us engaging in a Canton Coin treasury strategy have created, and could continue to create complications due to the lack of experience that third parties have with companies engaging in such a strategy, such as increased costs of director and officer liability insurance or the potential inability to obtain such coverage on acceptable terms in the future.

Our Digital Asset Treasury ("DAT") exposure to Canton Coin ("CC") involves novel and significant risks-including market volatility, accounting, regulatory, custody, cybersecurity, liquidity and reputational risks-that could result in the loss of assets and have a material adverse effect on our business, results of operations and financial condition.

We intend to implement a digital asset treasury ("DAT") by holding our treasury assets in Canton Coin ("CC"), a privately issued digital asset that is not legal tender and is not backed or insured by any government or governmental program. The market for CC may be less mature than markets for traditional assets and can exhibit extreme price volatility driven by factors beyond our control, including market sentiment, macroeconomic conditions, regulatory developments, protocol or governance changes, technological vulnerabilities and the actions of significant market participants. These price movements could result in substantial realized and unrealized gains or losses. Under applicable U.S. GAAP, crypto assets that meet the relevant criteria are measured at fair value each reporting period with changes recognized in earnings, which can produce meaningful volatility in our reported results and adversely affect the market price of our securities.

Our CC activities depend on third-party service providers-such as trading venues, custodians, wallet-infrastructure vendors and banking or payment partners-over which we have limited control. Failures or outages at these providers, trading suspensions or delistings, withdrawal moratoria, insolvencies, hacking, fraud, operational errors, inadequate asset segregation or adverse legal determinations could lead to the partial or total loss of CC, delays or an inability to access or deploy CC, or disputes regarding ownership and control. Safeguarding the private keys necessary to access and transfer CC presents unique cybersecurity and internal-control challenges; loss, theft or compromise of keys-through cyberattack, insider malfeasance, software defects, misconfiguration, phishing or social engineering-may be irreversible.

The legal and regulatory framework for digital assets, including CC, continues to evolve and may be subject to inconsistent interpretation across U.S. federal, state and international jurisdictions. Authorities could determine that CC is a security, commodity or other regulated instrument, which could impose registration, licensing, disclosure, custody, capital or other obligations. Changes in, or differing interpretations of, securities, commodities, money-transmission, sanctions/AML, consumer-protection, tax and data-security laws and regulations could increase our compliance costs, restrict or prohibit aspects of our CC activities, limit access to fiat banking or payment rails, or subject us to examinations, enforcement actions, penalties or private litigation.

Liquidity in markets for CC may be limited or impaired during periods of stress due to exchange outages, extreme volatility, order-book dislocations, widening spreads and slippage, or adverse developments in related market infrastructure (including stablecoins and key service providers). If we seek to sell, transfer or hedge CC during such periods, we may be unable to do so on acceptable terms, or at all. Our holdings may also be concentrated in CC, increasing our exposure to idiosyncratic risks and potentially causing our stock price to correlate with movements in the price of CC.

Allocating cash, offering proceeds or debt financing to acquire or hold CC could affect our capital needs and financing plans, increase dilution or leverage, and subject us to covenant constraints. In addition, certain stakeholders may view digital-asset exposure unfavorably-whether due to environmental, social or governance concerns, perceived risk or other reasons-which could impair our reputation and access to capital, customers and partners. We may modify, suspend or discontinue our CC activities at any time, and there can be no assurance that our DAT strategy will achieve its objectives or that losses will not occur.

Regulatory change reclassifying Canton Coin as a security could lead to our classification as an "investment company" under the Investment Company Act of 1940, as amended, or the 1940 Act, and could adversely affect the market price of Canton Coin and the market price of our Common Stock.

Under Sections 3(a)(1)(A) and (C) of the 1940 Act, a company generally will be deemed to be an "investment company" for purposes of the 1940 Act if (1) it is, or holds itself out as being, engaged primarily, or proposes to engage primarily, in the business of investing, reinvesting or trading in securities or (2) it engages, or proposes to engage, in the business of investing, reinvesting, owning, holding or trading in securities and it owns or proposes to acquire investment securities having a value exceeding 40% of the value of its total assets (exclusive of U.S. government securities and cash items) on an unconsolidated basis. We do not believe that we are an "investment company," as such term is defined in the 1940 Act, and are not registered as an "investment company" under the 1940 Act as of the date of this prospectus.

While senior SEC officials have not stated their view as to whether Canton Coin is or is not a "security" for purposes of the federal securities laws, a contrary determination by the SEC could lead to our classification as an "investment company" under the 1940 Act, if the portion of our assets consists of investments in Canton Coins exceeds 40% safe harbor limits prescribed in the 1940 Act, which would subject us to significant additional regulatory controls that could have a material adverse effect on our business and operations and may also require us to change the manner in which we conduct our business.

We monitor our assets and income for compliance under the 1940 Act and seek to conduct our business activities in a manner such that we do not fall within its definitions of "investment company" or that we qualify under one of the exemptions or exclusions provided by the 1940 Act and corresponding SEC regulations. Furthermore, if Canton Coin is determined to constitute a security for purposes of the federal securities laws, we would take steps to reduce the percentage of Canton Coins that constitute investment assets under the 1940 Act. These steps may include, among others, selling Canton Coins that we might otherwise hold for the long term and deploying our cash in non-investment assets, and we may be forced to sell our Canton Coins at unattractive prices. We may also seek to acquire additional non-investment assets to maintain compliance with the 1940 Act, and we may need to incur debt, issue additional equity or enter into other financing arrangements that are not otherwise attractive to our business. Any of these actions could have a material adverse effect on our results of operations and financial condition. Moreover, we can make no assurance that we would successfully be able to take the necessary steps to avoid being deemed to be an investment company in accordance with the safe harbor. If we were unsuccessful, and if Canton Coin is determined to constitute a security for purposes of the federal securities laws, then we would have to register as an investment company, and the additional regulatory restrictions imposed by 1940 Act could adversely affect the market price of Canton Coin and in turn adversely affect the market price of our Common Stock.

Our financial results and the market price of our Common Stock may be affected by the prices of Canton Coin.

As part of our capital allocation strategy for assets that are not required to provide working capital for our ongoing operations, we intend to invest in Canton Coin tokens. The price of Canton Coin has historically been subject to dramatic price fluctuations and is highly volatile. Moreover, digital assets, such as Canton Coin, are relatively novel and the application of securities laws and other regulations to such assets is unclear in many respects. It is possible that regulators may interpret laws in a manner that adversely affects the liquidity or value of Canton Coin.

Any decrease in the fair value of Canton Coin below our carrying value for such assets could require us to incur a loss due to the decrease in fair market value, and such charge could be material to our financial results for the applicable reporting period, which may create significant volatility in our reported earnings. Any decrease in reported earnings or increased volatility of such earnings could have a material adverse effect on the market price of our Common Stock. In addition, the application of generally accepted accounting principles in the United States, with respect to Canton Coin, may change in the future and could have a material adverse effect on our financial results and the market price of our Common Stock.

In addition, if investors view the value of our Common Stock as dependent upon or linked to the value or change in the value of our Canton Coin holdings, the price of Canton Coin may significantly influence the market price of our Common Stock. Additionally, if the price of Canton Coin falls, and our Common Stock price falls as a result, then the Notes may not be converted and we may, in certain situations, need to repay them in cash. To the extent the value of the Notes exceeds the value of the Canton Coin held as collateral, we may need to obtain additional financing, which might not be available on satisfactory terms or at all. Any deficiency could substantially exceed the value of our other assets and could be many multiples of our historical earnings.

We face risks relating to the custody of our Canton Coin tokens, including the loss or destruction of private keys required to access our Canton Coin tokens and cyberattacks or other data loss relating to our Canton Coin tokens, including smart contract related losses and vulnerabilities.

We hold our Canton Coin tokens with a single regulated custodian that has duties to safeguard our private keys. In light of the significant amount of Canton Coin tokens we anticipate that we will hold, we may need to engage additional custodians to achieve a greater degree of diversification in the custody of our Canton Coin tokens as the extent of potential risk of loss is dependent, in part, on the degree of diversification. However, multiple custodians may utilize similar wallet infrastructure, cloud service providers or software systems, which could increase systemic technology risk.

If there is a decrease in the availability of digital asset custodians that we believe can safely custody our Canton Coin tokens, for example, due to regulatory developments or enforcement actions that cause custodians to discontinue or limit their services in the United States, we may need to enter into agreements that are less favorable than our current agreements or take other measures to custody our Canton Coin tokens, and our ability to seek a greater degree of diversification in the use of custodial services would be materially adversely affected. While we will conduct due diligence on our custodians and any smart contract platforms we may use, there can be no assurance that such diligence will uncover all risks, including operational deficiencies, hidden vulnerabilities or legal noncompliance.

Currently, the insurance that covers losses of our Canton Coin holdings may cover none or only a small fraction of the value of the entirety of our Canton Coin holdings, and there can be no guarantee that such insurance will be maintained as part of the custodial services we have or that such coverage will cover losses with respect to our Canton Coin. Moreover, our use of custodians exposes us to the risk that the Canton Coin our custodians hold on our behalf could be subject to insolvency proceedings and we could be treated as a general unsecured creditor of the custodian, inhibiting our ability to exercise ownership rights with respect to such Canton Coin. Any loss associated with such insolvency proceedings is unlikely to be covered by any insurance coverage we maintain related to our Canton Coin. The legal framework governing digital asset ownership and rights in custodial or insolvency contexts remains uncertain and continues to evolve, which could result in unexpected losses, protracted recovery processes or adverse treatment in insolvency proceedings.

Canton Coin tokens are controllable only by the possessor of both the unique public key and private key(s) relating to the local or online digital wallet in which the Canton Coin is held. While the Canton Coin blockchain ledger requires a public key relating to a digital wallet to be published when used in a transaction, private keys must be safeguarded and kept private in order to prevent a third party from accessing the Canton Coin held in such wallet. To the extent the private key(s) for a digital wallet are lost, destroyed, or otherwise compromised and no backup of the private key(s) is accessible, neither we nor our custodians will be able to access the Canton Coin held in the related digital wallet. Furthermore, we cannot provide assurance that our digital wallets, nor the digital wallets of our custodians held on our behalf, will not be compromised as a result of a cyberattack. The Canton Coin and blockchain ledger, as well as other digital assets and blockchain technologies, have been, and may in the future be, subject to security breaches, cyberattacks, or other malicious activities.

As part of our treasury management strategy, we may engage in staking, restaking, or other permitted activities that involve the use of "smart contracts" or decentralized applications. The use of smart contracts or decentralized applications entails certain risks including risks stemming from the existence of an "admin key" or coding flaws that could be exploited, potentially allowing a bad actor to issue or otherwise compromise the smart contract or decentralized application, potentially leading to a loss of our Canton Coin tokens. Like all software code, smart contracts are exposed to risk that the code contains a bug or other security vulnerability, which can lead to loss of assets that are held on or transacted through the contract or decentralized application. Smart contracts and decentralized applications may contain bugs, security vulnerabilities or poorly designed permission structures that could result in the irreversible loss of Canton Coin tokens or other digital assets. Exploits, including those stemming from admin key misuse, admin key compromise, or protocol flaws, have occurred in the past and may occur in the future.

If we or our third-party service providers experience a security breach or cyberattack and unauthorized parties obtain access to our Canton Coin, or if our private keys are lost or destroyed, or other similar circumstances or events occur, we may lose some or all of our Canton Coin and our financial condition and results of operations could be materially adversely affected.

Substantially all of the Canton Coin we own is held in custody accounts at U.S.-based institutional-grade digital asset custodians. Security breaches and cyberattacks are of particular concern with respect to our Canton Coin. Canton Coin and other blockchain-based cryptocurrencies and the entities that provide services to participants in the Canton Coin ecosystem have been, and may in the future be, subject to security breaches, cyberattacks, or other malicious activities. For example, in October 2021 it was reported that hackers exploited a flaw in the account recovery process and stole from the accounts of at least 6,000 customers of the Coinbase exchange, although the flaw was subsequently fixed and Coinbase reimbursed affected customers. Similarly, in November 2022, hackers exploited weaknesses in the security architecture of the FTX Trading digital asset exchange and reportedly stole over $400 million in digital assets from customers. A successful security breach or cyberattack could result in:

	●	a partial or total loss of our Canton Coin in a manner that may not be covered by insurance or the liability provisions of the custody agreements with the custodians who hold our Canton Coin;
	●	improper disclosure of data and violations of applicable data privacy and other laws; or
	●	significant regulatory scrutiny, investigations, fines, penalties, and other legal, regulatory, contractual and financial exposure.

Further, any actual or perceived data security breach or cybersecurity attack directed at other companies with digital assets or companies that operate digital asset networks, regardless of whether we are directly impacted, could lead to a general loss of confidence in the broader Canton Coin ecosystem or in the use of the Canton Coin network to conduct financial transactions, which could negatively impact the market price of Canton Coin and in turn negatively impact our financial condition and results of operations and the market price of our Common Stock.

Attacks upon systems across a variety of industries, including industries related to Canton Coin, are increasing in frequency, persistence, and sophistication, and, in many cases, are being conducted by sophisticated, well-funded and organized groups and individuals, including state actors. The techniques used to obtain unauthorized, improper or illegal access to systems and information (including personal data and digital assets), disable or degrade services, or sabotage systems are constantly evolving, may be difficult to detect quickly, and often are not recognized or detected until after they have been launched against a target. These attacks may occur on our systems or those of our third-party service providers or partners. We may experience breaches of our security measures due to human error, malfeasance, insider threats, system errors or vulnerabilities or other irregularities. In particular, we expect that unauthorized parties will attempt to gain access to our systems and facilities, as well as those of our partners and third-party service providers, through various means, such as hacking, social engineering, phishing and fraud. Threats can come from a variety of sources, including criminal hackers, hacktivists, state-sponsored intrusions, industrial espionage, and insiders. In addition, certain types of attacks could harm us even if our systems are left undisturbed. For example, certain threats are designed to remain dormant or undetectable, sometimes for extended periods of time, or until launched against a target and we may not be able to implement adequate preventative measures. Further, there has been an increase in such activities due to the increase in work-from-home arrangements. The risk of cyberattacks could also be increased by cyberwarfare in connection with ongoing or future armed conflicts, including potential proliferation of malware into systems unrelated to such conflicts. Any future breach of our operations or those of others in the Canton Coin industry, including third-party services on which we rely, could materially and adversely affect our financial condition and results of operations.

We face other risks related to our Canton Coin treasury reserve business model.

Our Canton Coin treasury reserve business model exposes us to various risks, including the following:

	●	Canton Coin and other digital assets are subject to significant legal, commercial, regulatory, and technical uncertainty, and our Canton Coin strategy subjects us to enhanced regulatory oversight;
	●	regulatory changes could impact our ability to operate validators or receive rewards;
	●	regulatory scrutiny of the Company's activities may increase, potentially limiting our operations;
	●	potential litigation risks exist related to smart contract vulnerabilities, validator operations, or our business activities;
	●	uncertainty around Canton Coin's regulatory status may impact our ability to list on certain exchanges;
	●	changes in political administration may not guarantee a favorable regulatory environment for Canton Coin; and
	●	increased regulatory focus on Layer-1 blockchains beyond Bitcoin and Ethereum could result in new compliance requirements.

The foregoing factors could lead to disruption in the market for Canton Coin, which could adversely affect the market price of Canton Coin and in turn adversely affect the market price of our Common Stock.

We do not currently have a chief financial officer or internal accounting and finance staff, and failing to maintain effective internal controls in accordance with Section 404(a) of the Sarbanes-Oxley Act could result in material weaknesses in our internal controls and have a material adverse effect on our business and stock price.

As a publicly traded company, we are required to comply with the SEC rules implementing Sections 302 and 404(a) of the Sarbanes-Oxley Act, which requires management to certify financial and other information in our quarterly and annual reports and provide an annual management report on the effectiveness of controls over financial reporting. Our former Chief Executive Officer, Sireesh Appajosyula, has served as our principal financial and principal accounting officer, through November 6, 2025. We do not currently have any internal accounting and finance staff. Currently, we rely on independent third-party consultants to provide important finance and accounting services. If the consultants to which we outsource these functions do not perform effectively, we may experience errors in recording, disclosure, and presentation of our consolidated financial information in quarterly, annual, and other filings. Such errors may also lead to, among other things, business disruption, increased operating costs, significant deficiencies or material weaknesses in our internal controls over financial reporting.

Although we review our internal controls over financial reporting in order to ensure compliance with Section 404 requirements, having a chief financial officer and additional staff focused on accounting and finance would reduce the likelihood of errors related to the recording, disclosure, and presentation of consolidated financial information in quarterly, annual, and other filings. Material weaknesses could result in an adverse reaction in the financial marketplace due to a loss of investor confidence in the reliability of our financial statements, which ultimately could negatively impact our stock price as well as adversely affect our business, prospects, liquidity, financial condition and results of operations.

There are inherent limitations in the effectiveness of any control system, including the potential for human error and the possible circumvention or overriding of controls and procedures. Additionally, judgments in decision-making can be faulty and breakdowns can occur because of a simple error or mistake. An effective control system can provide only reasonable, not absolute, assurance that the control objectives of the system are adequately met.

USE OF PROCEEDS

We may issue and sell shares of our Common Stock having aggregate gross sales proceeds of up to $64,910,101 from time to time. Because there is no minimum offering price for the shares that we may offer from time to time, the actual total public offering amount, commissions and proceeds to us, if any, are not determinable at this time. There can be no assurance that we will sell any shares under or fully utilize the Sales Agreement with the Sales Agents as a source of financing.

We currently expect to use the net proceeds from this offering primarily to acquire to the purchasing, long-term holding, and staking of Canton Coin, including operating Canton Coin validators to earn rewards and contribute to the Canton Network's security and decentralization and reinvesting staking yields to further expand our Canton Coin holdings and strengthen our engagement within the Canton Coin ecosystem. We also intend to use the proceeds from this offering for working capital needs and general corporate expenses, which may include funding acquisitions or investments in businesses, products or technologies that are complementary to our own.

This expected use of the net proceeds from this offering represents our intentions based upon our current plans and business conditions, and our management will retain broad discretion as to the ultimate allocation of the proceeds. We may temporarily invest funds that we do not immediately need for these purposes in investment securities or use them to make payments on our borrowings. As of the date of this prospectus supplement, we cannot specify with certainty all of the particular uses for the net proceeds from this offering. The amounts and timing of our actual expenditures will depend on numerous factors, including factors described under "Risk Factors" in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference herein and therein. As a result, our management will have broad discretion in the application of the net proceeds, and investors will be relying on our judgment regarding the application of the net proceeds of this offering.

DIVIDEND POLICY

We have not declared or paid cash dividends on our Common Stock since our inception. Even if our board of directors ("Board") decides to pay dividends, the form, the frequency, and the amount will depend upon our future operations and earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that the Board may deem relevant. While our Board will make any future decisions regarding dividends, as circumstances surrounding us change, it currently does not anticipate that we will pay any cash dividends in the foreseeable future.

PLAN OF DISTRIBUTION

We have entered into a Sales Agreement with the Sales Agents under which we may offer and sell up to $64,910,161 of our shares of our Common Stock from time to time through the Sales Agents. Sales of our Common Stock, if any, made through the Sales Agents, or directly to the Sales Agents, as principals, as contemplated by this prospectus supplement and the accompanying prospectus, may be made in negotiated transactions, block trades or any method that is deemed to be an "at the market offering" as defined in Rule 415(a)(4) under the Securities Act, including sales made directly on the principal market on which our Common Stock is listed or any other existing trading market for our Common Stock.

Each time we wish to issue and sell our shares of Common Stock under the Sales Agreement, we will notify one of the Sales Agents of the number of shares to be issued, the dates on which such sales are anticipated to be made, any limitation on the number of shares to be sold in any one day and any minimum price below which sales may not be made. Once we have so instructed the Sales Agents, unless the Sales Agents decline to accept the terms of such notice, the Sales Agents have agreed to use their commercially reasonable efforts consistent with its normal trading and sales practices and applicable law and regulations to sell such shares up to the amount specified on such terms. The obligations of the Sales Agents under the Sales Agreement to sell our shares of Common Stock are subject to a number of conditions that we must meet.

The settlement of sales of shares between us and the executing Sales Agent is generally anticipated to occur on the first trading day following the date on which the sale was made. Sales of our shares of Common Stock as contemplated in this prospectus supplement will be settled through the facilities of The Depository Trust Company or by such other means as we and the Sales Agents may agree upon. There is no arrangement for funds to be received in an escrow, trust or similar arrangement.

We will pay the Sales Agents a commission of up to 3% of the aggregate gross proceeds we receive from each sale of our shares of Common Stock. Because there is no minimum offering amount required as a condition to close this offering, the actual total public offering amount, commissions and proceeds to us, if any, are not determinable at this time. In addition, we have agreed to reimburse the Sales Agents for the fees and disbursements of their counsel, payable upon execution of the Sales Agreement, in an amount not to exceed $75,000, in addition to certain ongoing disbursements of its legal counsel, unless we and the Sales Agents otherwise agree. We estimate that the total expenses for the offering, excluding any commissions or expense reimbursement payable to the Sales Agents under the terms of the Sales Agreement, will be approximately $200,000. The remaining sale proceeds, after deducting any other transaction fees, will equal our net proceeds from the sale of such shares.

The executing Sales Agent will provide written confirmation to us before the open on Nasdaq on the day following each day on which shares of Common Stock are sold under the Sales Agreement. Each confirmation will include the number of shares sold on that day, the aggregate gross proceeds of such sales and the proceeds to us.

Under the terms of the Sales Agreement, we also may sell our Common Stock to one or both of the Sales Agents as principals for their own accounts at a price agreed upon at the time of sale. The Sales Agents may offer our Common Stock sold to them as principal from time to time through public or private transactions at a price agreed upon at the time of sale. If we sell our Common Stock to one or both of the Sales Agents as principals, we will enter into a separate agreement with the applicable Sales Agent(s) setting forth the terms of such transaction, and, to the extent required by applicable law, we will describe that separate agreement in a separate prospectus supplement or pricing supplement.

In connection with the sale of our Common Stock on our behalf, the Sales Agents may be deemed to be "underwriters" within the meaning of the Securities Act, and the compensation of the Sales Agents may be deemed to be underwriting commissions or discounts. We have agreed to indemnify the Sales Agents against certain liabilities, including liabilities under the Securities Act. We have also agreed to contribute to payments the Sales Agents may be required to make in respect of such liabilities.

The Sales Agents are acting solely as agents in connection with the offering of the Company's Common Stock, except to the extent that the Company and the Sales Agents agree that one or both of the Sales Agents will act as a principal in connection with the sale of shares. The Sales Agent have not prepared, and are not responsible for, any statement or disclosures in this prospectus supplement or the accompanying prospectus, except for those statements made with the express written consent of the Sales Agents.

The offering of shares of Common Stock pursuant to the Sales Agreement will terminate upon the earlier of (i) the sale of all shares of Common Stock subject to the Sales Agreement and this prospectus supplement and (ii) the termination of the Sales Agreement according to its terms by either the Sales Agents or us.

This summary of the material provisions of the Sales Agreement does not purport to be a complete statement of its terms and conditions. A copy of the Sales Agreement is filed with the SEC as an exhibit to a Current Report on Form 8-K filed under the Exchange Act and incorporated by reference in this prospectus supplement.

The Sales Agents and their respective affiliates have provided and may in the future provide various investment banking, commercial banking, financial advisory and other financial services for us and our affiliates, for which services they have received and, may in the future receive, customary fees. In the course of their respective business, the Sales Agents may actively trade our securities for their own accounts or for the accounts of customers, and, accordingly, the Sales Agents may at any time hold long or short positions in such securities. Clear Street acted as the sole placement agent and a financial advisor to the Company in connection with the PIPE Transaction, and subscribed for shares of Common Stock and received the right to receive shares of Common Stock of the Company as a placement fee in connection with the PIPE Transaction.

In connection with its role as placement agent in the PIPE Transaction described elsewhere in this prospectus supplement, Clear Street was granted a right to participate as an underwriter, initial purchaser, or placement agent, as the case may be, with respect to any public or private offering of equity, equity-linked or debt securities, or a debt or debt-like financing within 12 months of the PIPE Transaction. Such participation rights were granted in compliance with FINRA Rule 5110(g)(6).

President Street, one of the participating Sales Agents, is an affiliate of the Company. For this reason, President Street is deemed to have a "conflict of interest" under FINRA Rule 5121. As such, this offering is being conducted in accordance with the applicable requirements of Rule 5121. Pursuant to FINRA Rule 5121(a)(1)(A), the appointment of a "qualified independent underwriter" is not required in connection with this offering as Clear Street, the member primarily responsible for managing the public offering, does not have a conflict of interest, is not an affiliate of any FINRA member that has a conflict of interest and meets the requirements of paragraph (f)(12)(E) of Rule 5121.

LEGAL MATTERS

Certain legal matters relating to the offering of the securities under this prospectus supplement will be passed upon for us by Lucosky Brookman LLP, Woodbridge, New Jersey. Clear Street is being represented in connection with this offering by Paul Hastings LLP.

Company References

In this prospectus "the Company," "we," "us," and "our" refer to Hillstream BioPharma, Inc., a Delaware corporation, and its subsidiaries, unless the context otherwise requires.

SUMMARY

Overview

Hillstream BioPharma is a pre-clinical biotechnology company developing novel therapeutic candidates targeting ferroptosis, an emerging new anti-cancer mechanism resulting in iron mediated cell death ("IMCD") and targeted immuno-oncology ("IO") novel biologics, for the treatment drug resistant cancers.

Our Lead Candidates

HSB-1216

Our most advanced product candidate, HSB-1216, is an IMCD inducer, targeting a variety of solid tumors. In a clinical pilot study conducted at the University of Heidelberg, Germany, the active drug in HSB-1216 was found to reduce tumor burden in treatment resistant cancers, including triple negative breast cancer ("TNBC") and epithelial carcinomas. We utilize Quatramer™, our proprietary tumor targeting platform, to enhance the uptake of HSB-1216 in the tumor microenvironment ("TME") with an extended duration of action and minimal off-target toxicity. Our goal is to submit an investigational new drug application ("IND") to the U.S. Food and Drug Administration ("FDA") and initiate a clinical study with HSB-1216 in the second half of 2023; however, no assurance can be provided that our IND will be accepted by the FDA in 2023, if at all. If our IND is accepted by the FDA, our HSB-1216 clinical study will focus on expanding upon the clinical pilot study conducted in Germany. If we are able to start our clinical study with HSB-1216 in the second half of 2023, we anticipate that clinical data from such trial will be released either late 2024 or early 2025.

The discovery of regulated cell death processes, such as apoptosis and autophagy, has enabled novel target discovery for drug development. Ferroptosis, a form of IMCD, is an emerging regulated cell death process which decreases intracellular iron, or the Labile Iron Pool ("LIP"), a known factor required for cell growth. Cancer cells promote increase in the LIP leading to unregulated cell growth and metabolism. Decreasing the LIP induces iron-led reactive oxygen species ("ROS") production and lipid peroxidation, two key hallmarks of ferroptosis/IMCD, which lead to regulated cell death. HSB-1216 sequesters iron in the cytoplasm of cancer cells and decreases the LIP, thereby inducing ferroptosis/IMCD, leading to regulated cell death. Areas of interest for the development of HSB-1216 are as a treatment of solid tumors, including small cell lung cancer, TNBC, uveal melanoma, glioblastoma multiforme, head and neck squamous cell carcinoma and other drug resistant cancers with high unmet need.

HSB-3215

Our second product candidate, HSB-1940, is an anti-HER2 monoclonal antibody candidate. The ErbB or HER family of cell surface proteins are some of the most well-known and validated oncology drug targets including ErbB2 or HER2 (human epidermal growth factor receptor) and Erb3 or HER3. Antibodies against HER2 and HER3 bind to different domains of the extracellular portion of the proteins or epitopes with trastuzumab primarily binding the extracellular domain IV of HER2. HER2 is a validated tumor antigen for antibody drug conjugates to treat HER2 positive cancers.

Applied Biomedical Science Institute ("ABSI") has developed technology to target unique functional epitopes of the cancer targets HER2 and HER3. Monoclonal antibodies being developed at ABSI are unique from the currently approved anti-HER2 antibodies. ABSI has granted us an exclusive option to license technology from ABSI to develop HER2 and HER3 antibodies, including multi-specific and Quatramer-based therapeutics incorporating portions of the antibodies. These antibodies could be incorporated into proprietary multi-format biologics (bi- and tri-specific antibodies, ADCs (antibody drug conjugates), CAR-T and CAR-NKs, in Quatramers and Quatrabodies) against drug resistant cancers including HER2-positive metastatic breast cancer, gastric cancer, lung cancer and ovarian cancer. The ABSI option terminates on March 24, 2023, unless extended by the parties.

HSB-1940

Our third product candidate, HSB-1940, is a Quatrabody, a proprietary IO biologic, in development targeting PD-1. We entered into a research collaboration and product license agreement with Minotaur Therapeutics, Inc. ("Minotaur") and a commercial license agreement with Taurus Biosciences, LLC ("Taurus"), for use of certain technology, including OmniAb antibodies, to advance Picobodies™ against novel, undruggable epitopes in high-value validated IO targets starting with PD-1. The technologies of Hillstream and Minotaur will be combined under the license from Taurus to discover, develop and advance biotherapeutics against high-value validated IO targets. Picobodies are bovine-derived antibody "knob" domains comprised of cysteine-rich ultralong complementary determining region ("CDR") H3 sequences of 30-40 amino acids weighing ~3-4 KDa, which have the potential to access challenging undruggable epitopes better than full size antibodies can. By combining Quatramers, with their long half-life, coated with a PD-1 Picobody to create HSB-1940, we believe we can more efficiently target novel epitopes with greater binding affinity than approved anti-PD-1 antibodies. We further believe that the development of HSB-1940 is a step toward enabling us to enter the rapidly growing IO market with additional targets thereafter.

Our Other Product Candidates

We intend to further develop our pipeline with novel bispecific monoclonal antibodies. These bispecific antibodies are planned to simultaneously bind to two different antigens or to two different epitopes on the same antigen. Whether two different antigens or two epitopes on the same antigen, the bispecific antibody could bind its targets either on the same cell (cis) or on to different cells (trans). Our strategy involves targeting PD-1 combined with a known, validated undisclosed antigen (HSB-9646) or using HER2 instead of PD-1 (HSB-0059), while naturally occurring antibodies typically only target one epitope on one antigen.

Our Platform Technologies

Quatramer Technology

Quatramer™ is a proprietary tumor targeting platform which allows us to leverage and exploit key tumor targets and novel emerging pathways such as IMCD to facilitate the delivery of potent drugs directly to the TME, while sparing healthy tissue. By efficiently extending the circulation half-life, as well as targeting delivery to the tumor site, Quatramer traps drugs into the TME. This emerging orthogonal anti-cancer approach leverages a fundamental recognized mechanism of iron mediated tumor growth and metabolism. We are building a portfolio of long-acting, potent anti-cancer drug candidates using our Quatramer platform.

Risks Associated with Our Business

Our ability to execute on our business strategy is subject to a number of risks, which are discussed more fully in the section titled "Risk Factors." Investors should carefully consider these risks before making an investment in our common stock. These risks include, among others, the following:

Risks Related to Our Financial Position and Need for Additional Capital

●	We have a limited operating history, and we have not initiated, conducted or completed any clinical trials, and have no products approved for commercial sale, which may make it difficult for you to evaluate our current business and likelihood of success and viability.
●	We have incurred significant losses since inception, we expect to incur losses in the future and we may not be able to generate sufficient revenue to achieve and maintain profitability.
●	We will require substantial additional capital to finance our operations in the future. If we are unable to raise such capital when needed, or on acceptable terms, we may be forced to curtail, delay or discontinue one or more of development programs or future commercialization efforts.
●	Management has performed an analysis and concluded that there is a substantial doubt about our ability to continue as a going concern. Separately, our independent registered public accounting firm has also concluded there exists a substantial doubt about our ability to continue as a going concern, which may hinder our ability to obtain future financing.

Risks Related to the Discovery and Development of Our Product Candidates

●	We are substantially dependent on the success of our product candidates. If we are unable to complete development of, obtain approval for and commercialize our product candidates in a timely manner, our business may be harmed.
●	Any delays in the commencement or completion, or termination or suspension, of our ongoing, planned or future clinical trials could result in increased costs to us, delay or limit our ability to generate revenue and adversely affect our commercial prospects.
●	The outcome of pre-clinical testing and early clinical trials may not be predictive of the success of later clinical trials, and the results of our clinical trials may not satisfy the requirements of the U.S. Food and Drug Administration or other comparable foreign regulatory authorities.
●	If we experience delays or difficulties in enrolling patients in our ongoing or planned clinical trials, our receipt of necessary regulatory approval could be delayed or prevented.
●	We may be required to perform additional or unanticipated clinical trials to obtain approval or be subject to post-marketing testing requirements to maintain regulatory approval. If our candidates prove to be ineffective, unsafe or commercially unviable, our entire technology platform and pipeline would have little, if any, value, which would have a material and adverse effect on our business, financial condition, results of operations and prospects.
●	Adverse side effects or other safety risks associated with our drug candidates could delay or preclude approval, cause us to suspend or discontinue clinical trials or abandon further development, limit the commercial profile of an approved label, or result in significant negative consequences following marketing approval, if any.
●	Our products may never achieve market acceptance.
●	We face significant competition, and if our competitors develop and market technologies or products more rapidly than we do or that are more effective, safer or less expensive than the products we develop, our commercial opportunities will be negatively impacted.
●	Our business may be adversely affected by the coronavirus pandemic.

Risks Related to Our Reliance on Third Parties

●	We rely on third parties to manufacture our product candidates and conduct our pre-clinical studies and clinical trials. If these third parties do not successfully perform their contractual and regulatory duties or meet expected deadlines, we may not be able to obtain regulatory approval for or commercialize our drug candidates and our business could be substantially harmed.
●	We currently depend on sole source suppliers and manufacturers for certain ingredients, and the inability to obtain such ingredients as required could harm our business.

Risks Related to Commercialization of Our Drug Candidates

●	Even if we are successful in completing all pre-clinical studies and clinical trials, we may not be successful in commercializing one or more of our drug candidates.
●	The development and commercialization of pharmaceutical products are subject to extensive regulation, and we may not obtain regulatory approvals for our drug candidates on a timely basis, or at all.

Risks Related to Our Intellectual Property

●	Our inability to protect our intellectual property and proprietary rights may have a material adverse effect on our business.

Risks Related to Managing Our Business and Operations

●	We may encounter difficulties in managing our growth, which could adversely affect our operations.
●	Our employees, independent contractors, consultants, commercial partners, collaborators and vendors may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements.

Risks Related to Our Common Stock

●	We are currently listed on The Nasdaq Capital Market. If we are unable to maintain listing of our securities on Nasdaq or any stock exchange, our stock price could be adversely affected and the liquidity of our stock and our ability to obtain financing could be impaired and it may be more difficult for our stockholders to sell their securities.
●	Our principal stockholders and management own a significant percentage of our stock and will be able to exert significant control over matters subject to stockholder approval.
●	We do not intend to pay dividends on our common stock so any returns will be limited to the value of our stock.

A prospectus supplement and any related free writing prospectus that we may authorize to be provided to you may also add, update, or change information contained in this prospectus or in documents we have incorporated by reference. However, no prospectus supplement or free writing prospectus will offer a security that is not registered and described in this prospectus at the time of the effectiveness of the registration statement of which this prospectus is a part.

We may sell the securities to or through underwriters, dealers or agents or directly to purchasers. We, as well as any agents acting on our behalf, reserve the sole right to accept and to reject in whole or in part any proposed purchase of securities. Each prospectus supplement will set forth the names of any underwriters, dealers or agents involved in the sale of securities described in that prospectus supplement and any applicable fee, commission or discount arrangements with them, details regarding any over-allotment option granted to them, and net proceeds to us. The following is a summary of the securities we may offer with this prospectus.

Common Stock

We currently have authorized 250,000,000 shares of common stock, par value $0.0001 per share. As of March 10, 2023, 11,514,144 shares of common stock were issued and outstanding. We may offer shares of our common stock either alone or underlying other registered securities convertible into or exercisable for our common stock. Holders of our common stock are entitled to such dividends as our board of directors (the "Board of Directors" or "Board") may declare from time to time out of legally available funds, subject to the preferential rights of the holders of any shares of our preferred stock that are outstanding or that we may issue in the future. Currently, we do not pay any dividends on our common stock. Each holder of our common stock is entitled to one vote per share held on all matters submitted to a vote of our stockholders. In this prospectus, we provide a general description of, among other things, the rights and restrictions that apply to holders of our common stock.

Preferred Stock

We currently have authorized 10,000,000 shares of preferred stock, par value $0.0001, none of which are issued and outstanding.

Any authorized and undesignated shares of preferred stock may be issued from time to time in one or more series pursuant to a resolution or resolutions providing for such issue duly adopted by our Board of Directors (authority to do so being hereby expressly vested in the Board of Directors). The Board of Directors is further authorized, subject to limitations prescribed by law, to fix by resolution or resolutions the designations, powers, preferences and rights, and the qualifications, limitations or restrictions thereof, of any wholly unissued series of preferred stock, including, without limitation, authority to fix by resolution or resolutions the dividend rights, dividend rate, conversion rights, voting rights, rights and terms of redemption (including sinking fund provisions), redemption price or prices, and liquidation preferences of any such series, and the number of shares constituting any such series and the designation thereof, or any of the foregoing.

The rights, preferences, privileges, and restrictions granted to or imposed upon any series of preferred stock that we offer and sell under this prospectus and applicable prospectus supplements will be set forth in a certificate of designation relating to the series. We will incorporate by reference into the registration statement of which this prospectus is a part the form of any certificate of designation that describes the terms of the series of preferred stock we are offering before the issuance of shares of that series of preferred stock. You should read any prospectus supplement and any free writing prospectus that we may authorize to be provided to you related to the series of preferred stock being offered, as well as the complete certificate of designation that contains the terms of the applicable series of preferred stock.

Debt Securities

We may offer general debt obligations, which may be secured or unsecured, senior or subordinated, and convertible into shares of our common stock or preferred stock. In this prospectus, we refer to the senior debt securities and the subordinated debt securities together as the "debt securities." We may issue debt securities under a note purchase agreement or under an indenture to be entered between us and a trustee. The indentures do not limit the amount of securities that may be issued under them and provide that debt securities may be issued in one or more series. The senior debt securities will have the same rank as all of our other indebtedness that is not subordinated. The subordinated debt securities will be subordinated to our senior debt on terms set forth in the applicable prospectus supplement. In addition, the subordinated debt securities will be effectively subordinated to creditors and preferred stockholders of our subsidiaries. Our Board of Directors will determine the terms of each series of debt securities being offered. This prospectus contains only general terms and provisions of the debt securities. The applicable prospectus supplement will describe the particular terms of the debt securities offered thereby. You should read any prospectus supplement and any free writing prospectus that we may authorize to be provided to you related to the series of debt securities being offered, as well as the complete note agreements and/or indentures that contain the terms of the debt securities. The forms of senior and subordinated indentures have been filed as exhibits to the registration statement of which this prospectus is a part, and supplemental indentures and forms of debt securities containing the terms of debt securities being offered will be incorporated by reference into the registration statement of which this prospectus is a part from reports we file with the SEC.

Warrants

We may offer warrants for the purchase of shares of our common stock or preferred stock or of debt securities. We may issue the warrants by themselves or together with common stock, preferred stock or debt securities, and the warrants may be attached to or separate from any offered securities. Any warrants issued under this prospectus may be evidenced by warrant certificates. Warrants may be issued under a separate warrant agreement to be entered into between us and the investors or a warrant agent. Our Board of Directors will determine the terms of the warrants. This prospectus contains only general terms and provisions of the warrants. The applicable prospectus supplement will describe the particular terms of the warrants being offered thereby. You should read any prospectus supplement and any free writing prospectus that we may authorize to be provided to you related to the series of warrants being offered, as well as the complete warrant agreements that contain the terms of the warrants. Specific warrant agreements will contain additional important terms and provisions and will be incorporated by reference into the registration statement of which this prospectus is a part from reports we file with the SEC.

Units

We may offer units consisting of our common stock or preferred stock, debt securities and/or warrants to purchase any of these securities in one or more series. We may evidence each series of units by unit certificates that we will issue under a separate agreement. We may enter into unit agreements with a unit agent. Each unit agent will be a bank or trust company that we select. We will indicate the name and address of the unit agent in the applicable prospectus supplement relating to a particular series of units. This prospectus contains only a summary of certain general features of the units. The applicable prospectus supplement will describe the particular features of the units being offered thereby. You should read any prospectus supplement and any free writing prospectus that we may authorize to be provided to you related to the series of units being offered, as well as the complete unit agreements that contain the terms of the units. Specific unit agreements will contain additional important terms and provisions and will be incorporated by reference into the registration statement of which this prospectus is a part from reports we file with the SEC.

RISK FACTORS

An investment in our securities involves a high degree of risk. This prospectus contains, and the prospectus supplement applicable to each offering of our securities will contain, a discussion of the risks applicable to an investment in our securities. Prior to making a decision about investing in our securities, you should carefully consider the specific factors discussed under the heading "Risk Factors" in this prospectus and the applicable prospectus supplement, together with all of the other information contained or incorporated by reference in the prospectus supplement or appearing or incorporated by reference in this prospectus. You should also consider the risks, uncertainties and assumptions discussed under Item 1A, "Risk Factors," in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022, filed with the SEC on March 16, 2023, and incorporated herein by reference, as may be amended, supplemented or superseded from time to time by other reports we file with the SEC in the future and any prospectus supplement related to a particular offering. The risks and uncertainties we have described are not the only ones we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our operations. The occurrence of any of these known or unknown risks might cause you to lose all or part of your investment in the offered securities.

DISCLOSURE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus, any accompanying prospectus supplement, any related free writing prospectus and the documents incorporated by reference herein or therein contain, in addition to historical information, certain forward-looking statements within the meaning of Section 27A of the Securities Act or 1933, as amended (the "Securities Act"), and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), that include information relating to future events, future financial performance, strategies, expectations, competitive environment, regulatory environment and availability of resources. Such forward-looking statements include those that express plans, anticipation, intent, contingency, goals, targets or future development and/or otherwise are not statements of historical fact. These forward-looking statements are based on our current expectations and projections about future events and they are subject to risks and uncertainties known and unknown that could cause actual results and developments to differ materially from those expressed or implied in such statements.

In some cases, you can identify forward-looking statements by terminology, such as "expects," "anticipates," "intends," "estimates," "plans," "believes," "seeks," "may," "should", "could" or the negative of such terms or other similar expressions. Accordingly, these statements involve estimates, assumptions and uncertainties that could cause actual results to differ materially from those expressed in them. Any forward-looking statements are qualified in their entirety by reference to the factors discussed throughout this prospectus, any accompanying prospectus supplement or incorporated herein by reference.

Risks, uncertainties and other factors that may cause our actual results, performance or achievements to be different from those expressed or implied in our written or oral forward-looking statements may be found in this prospectus and any accompanying prospectus supplement under the heading "Risk Factors" and in our Annual Report on Form 10-K for the year ended December 31, 2022 under the headings "Risk Factors" and "Business," as may be amended, supplemented or superseded from time to time by other reports we file with the SEC in the future and any prospectus supplement related to a particular offering.

Forward-looking statements speak only as of the date they are made. You should not put undue reliance on any forward-looking statements. We assume no obligation to update forward-looking statements to reflect actual results, changes in assumptions or changes in other factors affecting forward-looking information, except to the extent required by applicable securities laws. If we do update one or more forward-looking statements, no inference should be drawn that we will make additional updates with respect to those or other forward-looking statements.

New factors emerge from time to time, and it is not possible for us to predict which factors will arise. In addition, we cannot assess the impact of each factor on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. We qualify all of the information presented in this prospectus, any accompanying prospectus supplement and incorporated herein by reference, and particularly our forward-looking statements, by these cautionary statements.

USE OF PROCEEDS

Except as described in any prospectus supplement and any free writing prospectus in connection with a specific offering, we currently intend to use the net proceeds from the sale of the securities offered under this prospectus for general corporate purposes, including the development and commercialization of our products, research and development, general and administrative expenses, license or technology acquisitions, and working capital and capital expenditures. We may also use the net proceeds to repay any debts and/or invest in or acquire complementary businesses, products, or technologies, although we have no current commitments or agreements with respect to any such investments or acquisitions as of the date of this prospectus. We have not determined the amount of net proceeds to be used specifically for the foregoing purposes. As a result, our management will have broad discretion in the allocation of the net proceeds and investors will be relying on the judgment of our management regarding the application of the proceeds of any sale of the securities. Pending use of the net proceeds, we intend to invest the proceeds in short-term, investment-grade, interest-bearing instruments.

Each time we offer securities under this prospectus, we will describe the intended use of the net proceeds from that offering in the applicable prospectus supplement. The actual amount of net proceeds we spend on a particular use will depend on many factors, including, our future capital expenditures, the amount of cash required by our operations, and our future revenue growth, if any. Therefore, we will retain broad discretion in the use of the net proceeds.

DESCRIPTION OF CAPITAL STOCK

General

The following description of our capital stock, together with any additional information we include in any applicable prospectus supplement or any related free writing prospectus, summarizes the material terms and provisions of our common stock and the preferred stock that we may offer under this prospectus. While the terms we have summarized below will apply generally to any future common stock or preferred stock that we may offer, we will describe the particular terms of any class or series of these securities in more detail in the applicable prospectus supplement. For the complete terms of our common stock and preferred stock, please refer to our Certificate of Incorporation, as amended ("Certificate of Incorporation"), and our Bylaws that are incorporated by reference into the registration statement of which this prospectus is a part or may be incorporated by reference in this prospectus or any applicable prospectus supplement. The terms of these securities may also be affected by Delaware General Corporation Law (the "DGCL"). The summary below and that contained in any applicable prospectus supplement or any related free writing prospectus are qualified in their entirety by reference to our Certificate of Incorporation and our Bylaws.

As of the date of this prospectus, our authorized capital stock consisted of 250,000,000 shares of common stock, $0.0001 par value per share, and 10,000,000 shares of preferred stock, $0.0001 par value per share. Our Board may establish the rights and preferences of the preferred stock from time to time. As of March 10, 2023, there were 11,514,144 shares of our common stock and no shares of our preferred stock issued and outstanding.

Common Stock

We are authorized to issue up to a total of 250,000,000 shares of common stock, par value $0.0001 per share. Holders of our common stock are entitled to one vote for each share held on all matters submitted to a vote of our stockholders. Holders of our common stock have no cumulative voting rights. All shares of common stock offered hereby will, when issued, be fully paid and nonassessable, including shares of common stock issued upon the exercise of common stock warrants or subscription rights, if any.

Further, holders of our common stock have no preemptive or conversion rights or other subscription rights. Upon our liquidation, dissolution or winding-up, holders of our common stock are entitled to share in all assets remaining after payment of all liabilities and the liquidation preferences of any of our outstanding shares of preferred stock. Subject to preferences that may be applicable to any outstanding shares of preferred stock, holders of our common stock are entitled to receive dividends, if any, as may be declared from time to time by our Board of Directors out of our assets which are legally available.

The holders of a majority of the shares of our capital stock, represented in person or by proxy, are necessary to constitute a quorum for the transaction of business at any meeting. If a quorum is present, an action by stockholders entitled to vote on a matter is approved if the number of votes cast in favor of the action exceeds the number of votes cast in opposition to the action, with the exception of the election of directors, which requires a plurality of the votes cast.

Preferred Stock

Our Board of Directors has the authority, without further action by the stockholders, to issue up to 10,000,000 shares of preferred stock in one or more series and to fix the designations, powers, preferences, privileges, and relative participating, optional, or special rights as well as the qualifications, limitations, or restrictions of the preferred stock, including dividend rights, conversion rights, voting rights, terms of redemption, and liquidation preferences, any or all of which may be greater than the rights of the common stock. Our Board of Directors, without stockholder approval, can issue preferred stock with voting, conversion, or other rights that could adversely affect the voting power and other rights of the holders of common stock. Preferred stock could be issued quickly with terms calculated to delay or prevent a change of control or make removal of management more difficult. Additionally, the issuance of preferred stock may have the effect of decreasing the market price of our common stock, and may adversely affect the voting and other rights of the holders of common stock. At present, we have no plans to issue any shares of preferred stock following this offering.

Anti-Takeover Effects of Certain Provisions of our Certificate of Incorporation, Bylaws and the DGCL

We are governed by the provisions of Section 203 of the DGCL. In general, Section 203 prohibits a publicly traded 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 a prescribed manner. A business combination includes mergers, asset sales or other transactions resulting in a financial benefit to the stockholder. An interested stockholder is a person who, together with affiliates and associates, owns (or within three years, did own) 15% or more of the corporation's voting stock, subject to certain exceptions. The statute could have the effect of delaying, deferring or preventing a change in control of our Company.

Our Certificate of Incorporation and Bylaws contain provisions that could have the effect of discouraging potential acquisition proposals or making a tender offer or delaying or preventing a change in control, including changes a stockholder might consider favorable. In particular, our Certificate of Incorporation and Bylaws, as applicable, among other things:

●

provide our Board of Directors with the ability to alter our bylaws without stockholder approval;

●

provide that vacancies on our Board of Directors may be filled by a majority of directors in office, although less than a quorum;

●

provide that special meetings of our stockholders may be called by our Board of Directors, our Chief Executive Officer, or our President (in the absence of a Chief Executive Officer), the Chairman of our Board of Directors or stockholders entitled to cast at least one-fifth of the votes which all stockholders are entitled to cast at the particular meeting; and

●

provide advance notice requires for stockholders seeking to bring business before our annual meeting of stockholders, or to nominate candidates for election as directors at our annual meeting of stockholders.

Such provisions may have the effect of discouraging a third-party from acquiring us, even if doing so would be beneficial to our stockholders. These provisions are intended to enhance the likelihood of continuity and stability in the composition of our Board of Directors and in the policies formulated by them, and to discourage some types of transactions that may involve an actual or threatened change in control of our Company. These provisions are designed to reduce our vulnerability to an unsolicited acquisition proposal and to discourage some tactics that may be used in proxy fights. We believe that the benefits of increased protection of our potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure our Company outweigh the disadvantages of discouraging such proposals because, among other things, negotiation of such proposals could result in an improvement of their terms.

However, these provisions could have the effect of discouraging others from making tender offers for our shares that could result from actual or rumored takeover attempts. These provisions also may have the effect of preventing changes in our management.

Listing

Our common stock is listed on The Nasdaq Capital Market under the trading symbol "HILS."

Transfer Agent and Registrar

The Transfer Agent and Registrar for our common stock is Pacific Stock Transfer Company.

DESCRIPTION OF DEBT SECURITIES

The following description, together with the additional information we include in any applicable prospectus supplements or free writing prospectuses, summarizes the material terms and provisions of the debt securities that we may offer under this prospectus. We may issue debt securities, in one or more series, as either senior or subordinated debt or as senior or subordinated convertible debt. While the terms we have summarized below will apply generally to any future debt securities we may offer under this prospectus, we will describe the particular terms of any debt securities that we may offer in more detail in the applicable prospectus supplement or free writing prospectus. The terms of any debt securities we offer under a prospectus supplement may differ from the terms we describe below. However, no prospectus supplement shall fundamentally change the terms that are set forth in this prospectus or offer a security that is not registered and described in this prospectus at the time of its effectiveness. As of the date of this prospectus, we have no outstanding registered debt securities. Unless the context requires otherwise, whenever we refer to the "indentures," we also are referring to any supplemental indentures that specify the terms of a particular series of debt securities.

We will issue any senior debt securities under the senior indenture that we will enter into with the trustee named in the senior indenture. We will issue any subordinated debt securities under the subordinated indenture and any supplemental indentures that we will enter into with the trustee named in the subordinated indenture. We have filed forms of these documents as exhibits to the registration statement, of which this prospectus is a part, and supplemental indentures and forms of debt securities containing the terms of the debt securities being offered will be filed as exhibits to the registration statement of which this prospectus is a part or will be incorporated by reference from reports that we file with the SEC.

The indentures will be qualified under the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"). We use the term "trustee" to refer to either the trustee under the senior indenture or the trustee under the subordinated indenture, as applicable.

The following summaries of material provisions of the senior debt securities, the subordinated debt securities and the indentures are subject to, and qualified in their entirety by reference to, all of the provisions of the indenture and any supplemental indentures applicable to a particular series of debt securities. We urge you to read the applicable prospectus supplements and any related free writing prospectuses related to the debt securities that we may offer under this prospectus, as well as the complete indentures that contains the terms of the debt securities. Except as we may otherwise indicate, the terms of the senior indenture and the subordinated indenture are identical.

General

The terms of each series of debt securities will be established by or pursuant to a resolution of our Board of Directors and set forth or determined in the manner provided in an officers' certificate or by a supplemental indenture. Debt securities may be issued in separate series without limitation as to aggregate principal amount. We may specify a maximum aggregate principal amount for the debt securities of any series. We will describe in the applicable prospectus supplement the terms of the series of debt securities being offered, including:

●

the title;

●

the principal amount being offered, and if a series, the total amount authorized and the total amount outstanding;

●

any limit on the amount that may be issued;

●

whether or not we will issue the series of debt securities in global form, and, if so, the terms and who the depositary will be;

●

the maturity date;

●

whether and under what circumstances, if any, we will pay additional amounts on any debt securities held by a person who is not a United States person for tax purposes, and whether we can redeem the debt securities if we have to pay such additional amounts;

●

the annual interest rate, which may be fixed or variable, or the method for determining the rate and the date interest will begin to accrue, the dates interest will be payable and the regular record dates for interest payment dates or the method for determining such dates;

●

Conversion or Exchange Rights

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

Consolidation, Merger or Sale

Unless we provide otherwise in the prospectus supplement applicable to a particular series of debt securities, the indentures will not contain any covenant that restricts our ability to merge or consolidate, or sell, convey, transfer or otherwise dispose of all or substantially all of our assets. However, any successor to or acquirer of such assets must assume all of our obligations under the indentures or the debt securities, as appropriate. If the debt securities are convertible into or exchangeable for our other securities or securities of other entities, the person with whom we consolidate or merge or to whom we sell all of our property must make provisions for the conversion of the debt securities into securities that the holders of the debt securities would have received if they had converted the debt securities before the consolidation, merger or sale.

Events of Default under the Indenture

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

●

if we fail to pay interest when due and payable and our failure continues for 90 days and the time for payment has not been extended;

●

if we fail to pay the principal, premium or sinking fund payment, if any, when due and payable at maturity, upon redemption or repurchase or otherwise, and the time for payment has not been extended;

●

if we fail to observe or perform any other covenant contained in the debt securities or the indentures, other than a covenant specifically relating to another series of debt securities, and our failure continues for 90 days after we receive notice from the trustee or we and the trustee receive notice from the holders of at least 25% in aggregate principal amount of the outstanding debt securities of the applicable series; and

●

if specified events of bankruptcy, insolvency or reorganization occur.

We will describe in each applicable prospectus supplement any additional events of default relating to the relevant series of debt securities.

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

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

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

●

the direction so given by the holder is not in conflict with any law or the applicable indenture; and

●

subject to its duties under the Trust Indenture Act, the trustee need not take any action that might involve it in personal liability or might be unduly prejudicial to the holders not involved in the proceeding.

The indentures will provide that if an event of default has occurred and is continuing, the trustee will be required in the exercise of its powers to use the degree of care that a prudent person would use in the conduct of its own affairs. The trustee, however, may refuse to follow any direction that conflicts with law or the indenture, or that the trustee determines is unduly prejudicial to the rights of any other holder of the relevant series of debt securities, or that would involve the trustee in personal liability. Prior to taking any action under the indentures, the trustee will be entitled to indemnification against all costs, expenses and liabilities that would be incurred by taking or not taking such action.

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

●

the holder has given written notice to the trustee of a continuing event of default with respect to that series;

●

the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series have made a written request and such holders have offered reasonable indemnity to the trustee or security satisfactory to it against any loss, liability or expense or to be incurred in compliance with instituting the proceeding as trustee; and

●

the trustee does not institute the proceeding, and does not receive from the holders of a majority in aggregate principal amount of the outstanding debt securities of that series other conflicting directions within 90 days after the notice, request and offer.

These limitations do not apply to a suit instituted by a holder of debt securities if we default in the payment of the principal, premium, if any, or interest on, the debt securities, or other defaults that may be specified in the applicable prospectus supplement.

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

The indentures will provide that if a default occurs and is continuing and is actually known to a responsible officer of the trustee, the trustee must mail to each holder notice of the default within the earlier of 90 days after it occurs and 30 days after it is known by a responsible officer of the trustee or written notice of it is received by the trustee, unless such default has been cured or waived. Except in the case of a default in the payment of principal or premium of, or interest on, any debt security or certain other defaults specified in an indenture, the trustee shall be protected in withholding such notice if and so long as the Board of Directors, the executive committee or a trust committee of directors, or responsible officers of the trustee, in good faith determine that withholding notice is in the best interests of holders of the relevant series of debt securities.

Modification of Indenture; Waiver

Subject to the terms of the indenture for any series of debt securities that we may issue, we and the trustee may change an indenture without the consent of any holders with respect to the following specific matters:

●

to fix any ambiguity, defect or inconsistency in the indenture;

●

to comply with the provisions described above under "Description of Debt Securities - Consolidation, Merger or Sale;"

●

to comply with any requirements of the SEC in connection with the qualification of any indenture under the Trust Indenture Act;

●

to add to, delete from or revise the conditions, limitations and restrictions on the authorized amount, terms or purposes of issue, authentication and delivery of debt securities, as set forth in the indenture;

●

to provide for the issuance of, and establish the form and terms and conditions of, the debt securities of any series as provided under "Description of Debt Securities - General," to establish the form of any certifications required to be furnished pursuant to the terms of the indenture or any series of debt securities, or to add to the rights of the holders of any series of debt securities;

●

to evidence and provide for the acceptance of appointment hereunder by a successor trustee;

●

to provide for uncertificated debt securities and to make all appropriate changes for such purpose;

●

to add such new covenants, restrictions, conditions or provisions for the benefit of the holders, to make the occurrence, or the occurrence and the continuance, of a default in any such additional covenants, restrictions, conditions or provisions an event of default or to surrender any right or power conferred to us in the indenture; or

●

to change anything that does not adversely affect the interests of any holder of debt securities of any series in any material respect.

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

●

extending the stated maturity of the series of debt securities;

●

reducing the principal amount, reducing the rate of or extending the time of payment of interest, or reducing any premium payable upon the redemption or repurchase of any debt securities; or

●

reducing the percentage of debt securities, the holders of which are required to consent to any amendment, supplement, modification or waiver.

Discharge

Each indenture provides that, subject to the terms of the indenture and any limitation otherwise provided in the prospectus supplement applicable to a particular series of debt securities, we may elect to be discharged from our obligations with respect to one or more series of debt securities, except for specified obligations, including obligations to:

●

register the transfer or exchange of debt securities of the series;

●

replace stolen, lost or mutilated debt securities of the series;

●

maintain paying agencies;

●

hold monies for payment in trust;

●

recover excess money held by the trustee;

●

compensate and indemnify the trustee; and

●

appoint any successor trustee.

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

Form, Exchange and Transfer

We will issue the debt securities of each series only in fully registered form without coupons and, unless we otherwise specify in the applicable prospectus supplement, in denominations of $1,000 and any integral multiple thereof. The indentures will provide that we may issue debt securities of a series in temporary or permanent global form and as book-entry securities that will be deposited with, or on behalf of, The Depository Trust Company or another depositary named by us and identified in a prospectus supplement with respect to that series. See "Legal Ownership of Securities" below for a further description of the terms relating to any book-entry securities.

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

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

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

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

●

issue, register the transfer of, or exchange any debt securities of that series during a period beginning at the opening of business 15 days before the day of mailing of a notice of redemption of any debt securities that may be selected for redemption and ending at the close of business on the day of the mailing; or

●

register the transfer of or exchange any debt securities so selected for redemption, in whole or in part, except the unredeemed portion of any debt securities we are redeeming in part.

Information Concerning the Trustee

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

Payment and Paying Agents

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

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

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

Governing Law

The indentures and the debt securities will be governed by and construed in accordance with the laws of the State of New York, except to the extent that the Trust Indenture Act is applicable.

Ranking Debt Securities

The subordinated debt securities will be unsecured and will be subordinate and junior in priority of payment to certain other indebtedness to the extent described in a prospectus supplement. The subordinated indenture does not limit the amount of subordinated debt securities that we may issue. It also does not limit us from issuing any other secured or unsecured debt.

The senior debt securities will be unsecured and will rank equally in right of payment to all our other senior unsecured debt. The senior indenture does not limit the amount of senior debt securities that we may issue. It also does not limit us from issuing any other secured or unsecured debt.

DESCRIPTION OF WARRANTS

The following description, together with the additional information we may include in any applicable prospectus supplements and free writing prospectuses, summarizes the material terms and provisions of the warrants that we may offer under this prospectus, which may consist of warrants to purchase common stock, preferred stock or debt securities and may be issued in one or more series. Warrants may be offered independently or together with common stock, preferred stock or debt securities offered by any prospectus supplement, and may be attached to or separate from those securities. While the terms we have summarized below will apply generally to any warrants that we may offer under this prospectus, we will describe the particular terms of any series of warrants that we may offer in more detail in the applicable prospectus supplement and any applicable free writing prospectus. The terms of any warrants offered under a prospectus supplement may differ from the terms described below. However, no prospectus supplement will fundamentally change the terms that are set forth in this prospectus or offer a security that is not registered and described in this prospectus at the time of its effectiveness.

We may issue the warrants under a warrant agreement that we will enter into with a warrant agent to be selected by us. If selected, the warrant agent will act solely as an agent of ours in connection with the warrants and will not act as an agent for the holders or beneficial owners of the warrants. If applicable, we will file as exhibits to the registration statement of which this prospectus is a part, or will incorporate by reference from a Current Report on Form 8-K that we file with the SEC, the form of warrant agreement, including a form of warrant certificate, that describes the terms of the particular series of warrants we are offering before the issuance of the related series of warrants. The following summaries of material provisions of the warrants and the warrant agreements are subject to, and qualified in their entirety by reference to, all the provisions of the warrant agreement and warrant certificate applicable to a particular series of warrants. We urge you to read the applicable prospectus supplement and any applicable free writing prospectus related to the particular series of warrants that we sell under this prospectus, as well as the complete warrant agreements and warrant certificates that contain the terms of the warrants.

General

We will describe in the applicable prospectus supplement the terms relating to a series of warrants, including:

●

the offering price and aggregate number of warrants offered;

●

the currency for which the warrants may be purchased;

●

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

●

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

●

in the case of warrants to purchase debt securities, the principal amount of debt securities purchasable upon exercise of one warrant and the price at, and currency in which, this principal amount of debt securities may be purchased upon such exercise;

●

in the case of warrants to purchase common stock or preferred stock, the number of shares of common stock or preferred stock, as the case may be, purchasable upon the exercise of one warrant and the price at which these shares may be purchased upon such exercise;

●

the effect of any merger, consolidation, sale or other disposition of our business on the warrant agreements and the warrants;

●

the terms of any rights to redeem or call the warrants;

●

any provisions for changes to or adjustments in the exercise price or number of securities issuable upon exercise of the warrants;

●

the dates on which the right to exercise the warrants will commence and expire;

●

the manner in which the warrant agreements and warrants may be modified;

●

United States federal income tax consequences of holding or exercising the warrants;

●

the terms of the securities issuable upon exercise of the warrants; and

●

any other specific terms, preferences, rights or limitations of or restrictions on the warrants.

Before exercising their warrants, holders of warrants will not have any of the rights of holders of the securities purchasable upon such exercise, including:

●

in the case of warrants to purchase debt securities, the right to receive payments of principal of, or premium, if any, or interest on, the debt securities purchasable upon exercise or to enforce covenants in the applicable indenture; or

●

in the case of warrants to purchase common stock or preferred stock, the right to receive dividends, if any, or, payments upon our liquidation, dissolution or winding up or to exercise voting rights, if any.

Exercise of Warrants

Each warrant will entitle the holder to purchase the securities that we specify in the applicable prospectus supplement at the exercise price that we describe in the applicable prospectus supplement. Unless we otherwise specify in the applicable prospectus supplement, holders of the warrants may exercise the warrants at any time up to the specified time on the expiration date that we set forth in the applicable prospectus supplement. After the close of business on the expiration date, unexercised warrants will become void.

Holders of the warrants may exercise the warrants by delivering the warrant certificate representing the warrants to be exercised together with specified information, and paying the required amount to the warrant agent in immediately available funds, as provided in the applicable prospectus supplement. We will set forth on the reverse side of the warrant certificate and in the applicable prospectus supplement the information that the holder of the warrant will be required to deliver to us or the warrant agent as applicable.

Upon receipt of the required payment and the warrant certificate properly completed and duly executed at the corporate trust office of the warrant agent or any other office indicated in the applicable prospectus supplement, we will issue and deliver the securities purchasable upon such exercise. If fewer than all of the warrants represented by the warrant certificate are exercised, then we will issue a new warrant certificate for the remaining amount of warrants. If we so indicate in the applicable prospectus supplement, holders of the warrants may surrender securities as all or part of the exercise price for warrants.

Enforceability of Rights by Holders of Warrants

If selected, each warrant agent will act solely as our agent under the applicable warrant agreement and will not assume any obligation or relationship of agency or trust with any holder of any warrant. A single bank or trust company may act as warrant agent for more than one issue of warrants. A warrant agent will have no duty or responsibility in case of any default by us under the applicable warrant agreement or warrant, including any duty or responsibility to initiate any proceedings at law or otherwise, or to make any demand upon us. Any holder of a warrant may, without the consent of the related warrant agent or the holder of any other warrant, enforce by appropriate legal action its right to exercise, and receive the securities purchasable upon exercise of, its warrants.

DESCRIPTION OF UNITS

The following description, together with the additional information we may include in any applicable prospectus supplements and free writing prospectuses, summarizes the material terms and provisions of the units that we may offer under this prospectus.

While the terms we have summarized below will apply generally to any units that we may offer under this prospectus, we will describe the particular terms of any series of units in more detail in the applicable prospectus supplement. The terms of any units offered under a prospectus supplement may differ from the terms described below. However, no prospectus supplement will fundamentally change the terms that are set forth in this prospectus or offer a security that is not registered and described in this prospectus at the time of its effectiveness.

We will file as exhibits to the registration statement of which this prospectus is a part, or will incorporate by reference from a Current Report on Form 8-K that we file with the SEC, the form of unit agreement that describes the terms of the series of units we are offering, and any supplemental agreements, before the issuance of the related series of units. The following summaries of material terms and provisions of the units are subject to, and qualified in their entirety by reference to, all the provisions of the unit agreement and any supplemental agreements applicable to a particular series of units. We urge you to read the applicable prospectus supplements related to the particular series of units that we sell under this prospectus, as well as the complete unit agreement and any supplemental agreements that contain the terms of the units.

General

We may issue units comprised of one or more debt securities, shares of common stock, shares of preferred stock and warrants in any combination. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security. The unit agreement under which a unit is issued 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.

We will describe in the applicable prospectus supplement the terms of the series of units, including:

●

the designation and terms of the units and of the securities comprising the units, including whether and under what circumstances those securities may be held or transferred separately;

●

any provisions of the governing unit agreement that differ from those described below; and

●

any provisions for the issuance, payment, settlement, transfer or exchange of the units or of the securities comprising the units.

The provisions described in this section, as well as those described under "Description of Capital Stock," "Description of Debt Securities" and "Description of Warrants" will apply to each unit and to any common stock, preferred stock, debt security or warrant included in each unit, respectively.

Unit Agent

The name and address of the unit agent, if any, for any units we offer will be set forth in the applicable prospectus supplement.

Issuance in Series

We may issue units in such amounts and in numerous distinct series as we determine.

Enforceability of Rights by Holders of Units

Each unit agent will act solely as our agent under the applicable unit agreement and will not assume any obligation or relationship of agency or trust with any holder of any unit. A single bank or trust company may act as unit agent for more than one series of units. A unit agent will have no duty or responsibility in case of any default by us under the applicable unit agreement or unit, including any duty or responsibility to initiate any proceedings at law or otherwise, or to make any demand upon us. Any holder of a unit may, without the consent of the related unit agent or the holder of any other unit, enforce by appropriate legal action its rights as holder under any security included in the unit.

We, the unit agents and any of their agents may treat the registered holder of any unit certificate as an absolute owner of the units evidenced by that certificate for any purpose and as the person entitled to exercise the rights attaching to the units so requested, despite any notice to the contrary. See "Legal Ownership of Securities."

LEGAL OWNERSHIP OF SECURITIES

We can issue securities in registered form or in the form of one or more global securities. We describe global securities in greater detail below. We refer to those persons who have securities registered in their own names on the books that we or any applicable trustee or depositary or warrant agent maintain for this purpose as the "holders" of those securities. These persons are the legal holders of the securities. We refer to those persons who, indirectly through others, own beneficial interests in securities that are not registered in their own names, as "indirect holders" of those securities. As we discuss below, indirect holders are not legal holders, and investors in securities issued in book-entry form or in street name will be indirect holders.

Book-Entry Holders

We may issue securities in book-entry form only, as we will specify in the applicable prospectus supplement. This means securities may be represented by one or more global securities registered in the name of a financial institution that holds them as depositary on behalf of other financial institutions that participate in the depositary's book-entry system. These participating institutions, which are referred to as participants, in turn, hold beneficial interests in the securities on behalf of themselves or their customers.

Only the person in whose name a security is registered is recognized as the holder of that security. Global securities will be registered in the name of the depositary or its participants. Consequently, for global securities, we will recognize only the depositary as the holder of the securities, and we will make all payments on the securities to the depositary. The depositary passes along the payments it receives to its participants, which in turn pass the payments along to their customers who are the beneficial owners. The depositary and its participants do so under agreements they have made with one another or with their customers; they are not obligated to do so under the terms of the securities.

As a result, investors in a global security will not own securities directly. Instead, they will own beneficial interests in a global security, through a bank, broker or other financial institution that participates in the depositary's book-entry system or holds an interest through a participant. As long as the securities are issued in global form, investors will be indirect holders, and not legal holders, of the securities.

Street Name Holders

We may terminate a global security or issue securities that are not issued in global form. In these cases, investors may choose to hold their securities in their own names or in "street name." Securities held by an investor in street name would be registered in the name of a bank, broker or other financial institution that the investor chooses, and the investor would hold only a beneficial interest in those securities through an account he or she maintains at that institution.

For securities held in street name, we or any applicable trustee or depositary will recognize only the intermediary banks, brokers and other financial institutions in whose names the securities are registered as the holders of those securities, and we or any such trustee or depositary will make all payments on those securities to them. These institutions pass along the payments they receive to their customers who are the beneficial owners, but only because they agree to do so in their customer agreements or because they are legally required to do so. Investors who hold securities in street name will be indirect holders, not legal holders, of those securities.

Legal Holders

Our obligations, as well as the obligations of any applicable trustee or third party employed by us or a trustee, run only to the legal holders of the securities. We do not have obligations to investors who hold beneficial interests in global securities, in street name or by any other indirect means. This will be the case whether an investor chooses to be an indirect holder of a security or has no choice because we are issuing the securities only in global form.

For example, once we make a payment or give a notice to the holder, we have no further responsibility for the payment or notice even if that holder is required, under agreements with its participants or customers or by law, to pass it along to the indirect holders but does not do so. Similarly, we may want to obtain the approval of the holders to amend an indenture, to relieve us of the consequences of a default or of our obligation to comply with a particular provision of an indenture, or for other purposes. In such an event, we would seek approval only from the legal holders, and not the indirect holders, of the securities. Whether and how the legal holders contact the indirect holders is up to the legal holders.

Special Considerations for Indirect Holders

If you hold securities through a bank, broker or other financial institution, either in book-entry form because the securities are represented by one or more global securities or in street name, you should check with your own institution to find out:

●

how it handles securities payments and notices;

●

whether it imposes fees or charges;

●

how it would handle a request for the holders' consent, if ever required;

●

whether and how you can instruct it to send you securities registered in your own name so you can be a legal holder, if that is permitted in the future;

●

how it would exercise rights under the securities if there were a default or other event triggering the need for holders to act to protect their interests; and

●

if the securities are in book-entry form, how the depositary's rules and procedures will affect these matters.

Global Securities

A global security is a security that represents one or any other number of individual securities held by a depositary. Generally, all securities represented by the same global securities will have the same terms.

Each security issued in book-entry form will be represented by a global security that we issue to, deposit with and register in the name of a financial institution or its nominee that we select. The financial institution that we select for this purpose is called the depositary. Unless we specify otherwise in the applicable prospectus supplement, The Depository Trust Company, New York, NY, known as DTC, will be the depositary for all securities issued in book-entry form.

A global security may not be transferred to or registered in the name of anyone other than the depositary, its nominee or a successor depositary, unless special termination situations arise. We describe those situations below under "- Special Situations When A Global Security Will Be Terminated." As a result of these arrangements, the depositary, or its nominee, will be the sole registered owner and legal holder of all securities represented by a global security, and investors will be permitted to own only beneficial interests in a global security. Beneficial interests must be held by means of an account with a broker, bank or other financial institution that in turn has an account with the depositary or with another institution that does. Thus, an investor whose security is represented by a global security will not be a legal holder of the security, but only an indirect holder of a beneficial interest in the global security.

If the prospectus supplement for a particular security indicates that the security will be issued as a global security, then the security will be represented by a global security at all times unless and until the global security is terminated. If termination occurs, we may issue the securities through another book-entry clearing system or decide that the securities may no longer be held through any book-entry clearing system.

Special Considerations For Global Securities

As an indirect holder, an investor's rights relating to a global security will be governed by the account rules of the investor's financial institution and of the depositary, as well as general laws relating to securities transfers. We do not recognize an indirect holder as a holder of securities and instead deal only with the depositary that holds the global security.

If securities are issued only as global securities, an investor should be aware of the following:

●

an investor cannot cause the securities to be registered in his or her name, and cannot obtain non-global certificates for his or her interest in the securities, except in the special situations we describe below;

●

an investor will be an indirect holder and must look to his or her own bank or broker for payments on the securities and protection of his or her legal rights relating to the securities, as we describe above;

●

an investor may not be able to sell interests in the securities to some insurance companies and to other institutions that are required by law to own their securities in non-book-entry form;

●

an investor may not be able to pledge his or her interest in the global security in circumstances where certificates representing the securities must be delivered to the lender or other beneficiary of the pledge in order for the pledge to be effective;

●

the depositary's policies, which may change from time to time, will govern payments, transfers, exchanges and other matters relating to an investor's interest in the global security. We and any applicable trustee have no responsibility for any aspect of the depositary's actions or for its records of ownership interests in the global security. We and the trustee also do not supervise the depositary in any way;

●

the depositary may, and we understand that DTC will, require that those who purchase and sell interests in the global security within its book-entry system use immediately available funds, and your broker or bank may require you to do so as well; and

●

financial institutions that participate in the depositary's book-entry system, and through which an investor holds its interest in the global security, may also have their own policies affecting payments, notices and other matters relating to the securities. There may be more than one financial intermediary in the chain of ownership for an investor. We do not monitor and are not responsible for the actions of any of those intermediaries.

Special Situations When A Global Security Will Be Terminated

In a few special situations described below, a global security will terminate and interests in it will be exchanged for physical certificates representing those interests. After that exchange, the choice of whether to hold securities directly or in street name will be up to the investor. Investors must consult their own banks or brokers to find out how to have their interests in securities transferred to their own names, so that they will be direct holders. We have described the rights of holders and street name investors above.

A global security will terminate when the following special situations occur:

●

if the depositary notifies us that it is unwilling, unable or no longer qualified to continue as depositary for that global security and we do not appoint another institution to act as depositary within 90 days;

●

if we notify any applicable trustee that we wish to terminate that global security; or

●

if an event of default has occurred with regard to securities represented by that global security and has not been cured or waived.

The applicable prospectus supplement may also list additional situations for terminating a global security that would apply only to the particular series of securities covered by the prospectus supplement. When a global security terminates, the depositary, and neither we, nor any applicable trustee, is responsible for deciding the names of the institutions that will be the initial direct holders.

PLAN OF DISTRIBUTION

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

●

through agents to the public or to investors;

●

to underwriters for resale to the public or to investors;

●

negotiated transactions;

●

block trades;

●

directly to investors; or

●

through a combination of any of these methods of sale.

As set forth in more detail below, the securities may be distributed from time to time in one or more transactions:

●

at a fixed price or prices, which may be changed;

●

at market prices prevailing at the time of sale;

●

at prices related to such prevailing market prices; or

●

at negotiated prices.

We will set forth in a prospectus supplement the terms of that particular offering of securities, including:

●

the name or names of any agents or underwriters;

●

the purchase price of the securities being offered and the proceeds we will receive from the sale;

●

any over-allotment options under which underwriters may purchase additional securities from us;

●

any agency fees or underwriting discounts and other items constituting agents' or underwriters' compensation;

●

any initial public offering price;

●

any discounts or concessions allowed or re-allowed or paid to dealers; and

●

any securities exchanges or markets on which such securities may be listed.

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

If underwriters are used in an offering, we will execute an underwriting agreement with such underwriters and will specify the name of each underwriter and the terms of the transaction (including any underwriting discounts and other terms constituting compensation of the underwriters and any dealers) in a prospectus supplement. The securities may be offered to the public either through underwriting syndicates represented by managing underwriters or directly by one or more investment banking firms or others, as designated. If an underwriting syndicate is used, the managing underwriter(s) will be specified on the cover of the prospectus supplement. If underwriters are used in the sale, the offered securities will be acquired by the underwriters for their own accounts and may be resold from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. Any public offering price and any discounts or concessions allowed or re-allowed or paid to dealers may be changed from time to time. Unless otherwise set forth in the prospectus supplement, the obligations of the underwriters to purchase the offered securities will be subject to conditions precedent and the underwriters will be obligated to purchase all of the offered securities if any are purchased.

We may grant to the underwriters options to purchase additional securities to cover over-allotments, if any, at the public offering price, with additional underwriting commissions or discounts, as may be set forth in a related prospectus supplement. The terms of any over-allotment option will be set forth in the prospectus supplement for those securities.

If we use a dealer in the sale of the securities being offered pursuant to this prospectus or any prospectus supplement, we will sell the securities to the dealer, as principal. The dealer may then resell the securities to the public at varying prices to be determined by the dealer at the time of resale. The names of the dealers and the terms of the transaction will be specified in a prospectus supplement.

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

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

In connection with the sale of the securities, underwriters, dealers or agents may receive compensation from us or from purchasers of the common stock for whom they act as agents in the form of discounts, concessions or commissions. Underwriters may sell the securities to or through dealers, and those dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters or commissions from the purchasers for whom they may act as agents. Underwriters, dealers and agents that participate in the distribution of the securities, and any institutional investors or others that purchase common stock 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 common stock by them may be deemed to be underwriting discounts and commissions under the Securities Act.

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

We may engage in at the market offerings into an existing trading market in accordance with Rule 415(a)(4) under the Securities Act. In addition, we may enter into derivative transactions with third parties (including the writing of options), or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection with such a transaction, the third parties may, pursuant to this prospectus and the applicable prospectus supplement, sell securities covered by this prospectus and the applicable prospectus supplement. If so, the third party may use securities 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 the 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. The third party in such sale transactions will be an underwriter and will be identified in the applicable prospectus supplement or in a post-effective amendment.

To facilitate an offering of a series of securities, persons participating in the offering may engage in transactions that stabilize, maintain, or otherwise affect the market price of the securities. This may include over-allotments or short sales of the securities, which involves the sale by persons participating in the offering of more securities than have been sold to them by us. In those circumstances, such persons would cover such over-allotments or short positions by purchasing in the open market or by exercising the over-allotment option granted to those persons. In addition, those persons may stabilize or maintain the price of the securities by bidding for or purchasing securities in the open market or by imposing penalty bids, whereby selling concessions allowed to underwriters or dealers participating in any such offering may be reclaimed if securities sold by them are repurchased in connection with stabilization transactions. 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. Such transactions, if commenced, may be discontinued at any time. We make no representation or prediction as to the direction or magnitude of any effect that the transactions described above, if implemented, may have on the price of our securities.

Unless otherwise specified in the applicable prospectus supplement, each class or series of securities will be a new issue with no established trading market, other than our common stock, which is listed on The Nasdaq Capital Market. We may elect to list any other class or series of securities on any exchange or market, but we are not obligated to do so. It is possible that one or more underwriters may make a market in a class or series of securities, but the underwriters will not be obligated to do so and may discontinue any market making at any time without notice. We cannot give any assurance as to the liquidity of the trading market for any of the securities.

In order to comply with the securities laws of some U.S. states or territories, if applicable, the securities offered pursuant to this prospectus will be sold in those states only through registered or licensed brokers or dealers. In addition, in some states 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 complied with.

Any underwriter may engage in overallotment, stabilizing transactions, short covering transactions and penalty bids in accordance with Regulation M under the Exchange Act. Overallotment involves sales in excess of the offering size, which create a short position. Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum. Short covering transactions involve purchases of the securities in the open market after the distribution is completed to cover short positions. Penalty bids permit the underwriters to reclaim a selling concession from a dealer when the securities originally sold by the dealer are purchased in a covering transaction to cover short positions. Those activities may cause the price of the securities to be higher than it would otherwise be. If commenced, the underwriters may discontinue any of these activities at any time.

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

The validity of the issuance of the securities offered hereby will be passed upon for us by Sheppard, Mullin, Richter & Hampton LLP, New York, NY. Additional legal matters may be passed upon for us or any underwriters, dealers or agents, by counsel that we will name in the applicable prospectus supplement.
