PROSPECTUS SUPPLEMENT

(To Prospectus dated June 8, 2021)

Up to $50,000,000

Common Stock

We have entered into an at-the-market sales agreement with BTIG, LLC, acting in its capacity as the sales agent, or BTIG, relating to the offer and sale of shares of our common stock, no par value, from time to time, having an aggregate offering price of up to $50,000,000.

Sales of our common stock, if any, under this prospectus supplement may be made in sales deemed to be “at-the-market” equity offerings as defined in Rule 415 promulgated under the Securities Act of 1933, as amended, or the Securities Act, including, without limitation, sales made directly on the Nasdaq Stock Market LLC, or Nasdaq, on any other existing trading market for the Common Stock or to or through a market maker or through an electronic communications network. BTIG is not required to sell any specific amount of securities, but will act as our sales agent on a best efforts basis and will use commercially reasonable efforts to sell on our behalf all of the common stock requested to be sold by us, consistent with its normal trading and sales practices, on mutually agreed terms between BTIG and us. There is no arrangement for funds to be received in any escrow, trust or similar arrangement.

BTIG will be entitled to compensation at a fixed commission rate of 3.0% of the gross proceeds from the sale of our common stock on our behalf pursuant to the sales agreement. In connection with the sale of the common stock on our behalf, BTIG will be deemed to be an “underwriter” within the meaning of the Securities Act and the compensation of BTIG will be deemed to be underwriting commissions or discounts. We have agreed to provide indemnification and contribution to BTIG against certain civil liabilities, including liabilities under the Securities Act or the Securities Exchange Act of 1934, as amended, or the Exchange Act. We may also sell some or all of the shares of common stock to the sales agent as principal for its own account at a price agreed upon at the time of sale.

Our common stock is listed on Nasdaq under the symbol “OCX.” The last reported sale price of our common stock on June 8, 2021 was $4.76 per share.

Investing in our common stock involves a high degree of risk. You should read this prospectus supplement and the accompanying prospectus carefully before you make your investment decision. See “Risk Factors” beginning on page S-5 of this prospectus supplement, as well as the documents incorporated by reference in this prospectus supplement.

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

ABOUT THIS PROSPECTUS SUPPLEMENT

This prospectus supplement is part of a registration statement that we have filed with the Securities and Exchange Commission, or SEC, utilizing a “shelf” registration process. Under the shelf registration process, we may offer shares of our common stock having an aggregate offering price of up to $240,000,000 under the accompanying prospectus. Under this prospectus supplement and the accompanying prospectus, we may offer shares of our common stock having an aggregate offering price of up to $50,000,000 from time to time at prices and on terms to be determined by market conditions at the time of offering.

We are providing information to you about this offering of shares of our common stock in two separate documents that are bound together: (1) this prospectus supplement, which describes the specific details regarding this offering; and (2) the accompanying prospectus, which provides general information, some of which may not apply to this offering. Generally, when we refer to this “prospectus,” we are referring to both documents combined.

If information in this prospectus supplement is inconsistent with the accompanying prospectus or with any document incorporated by reference that was filed with the SEC before the date of this prospectus supplement, you should rely on this prospectus supplement. Any statement so modified will be deemed to constitute a part of this prospectus only as so modified, and any statement so superseded will be deemed not to constitute a part of this prospectus. However, if any statement in one of these documents is inconsistent with a statement in another document having a later date—for example, a document incorporated by reference in this prospectus supplement, the statement in the document having the later date modifies or supersedes the earlier statement as our business, financial condition, results of operations and prospects may have changed since the earlier dates.

This prospectus supplement, the accompanying prospectus and the documents incorporated into each by reference herein and therein include important information about us, the securities being offered and other information you should know before investing in our securities. You should also read and consider information in the documents we have referred you to in the section of this prospectus supplement and the accompanying prospectus entitled “Where You Can Find More Information” and “Information Incorporated by Reference.”

You should rely only on the information contained in or incorporated by reference into this prospectus supplement and the accompanying prospectus and any free writing prospectus we may provide to you in connection with this offering and the information incorporated or deemed to be incorporated by reference therein. We have not, and BTIG has not, authorized anyone to provide you with information that is in addition to or different from that contained or incorporated by reference in this prospectus supplement and the accompanying prospectus. If anyone provides you with different or inconsistent information, you should not rely on it. We are not, and the sales agent is not, offering to sell these securities in any jurisdiction where the offer or sale is not permitted. You should not assume that the information contained or incorporated by reference in this prospectus supplement or the accompanying base prospectus is accurate as of any date other than as of the date of this prospectus supplement or the accompanying base prospectus, as the case may be, or in the case of the documents incorporated by reference, the date of such documents regardless of the time of delivery of this prospectus supplement and the accompanying prospectus or any sale of our securities. Our business, financial condition, liquidity, results of operations and prospects may have changed since those dates.

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 in this prospectus supplement 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.

We are offering to sell, and are seeking offers to buy, the common stock only in jurisdictions where such offers and sales are permitted. No action has been or will be taken in any jurisdiction by us or BTIG that would permit a public offering of the common stock or the possession or distribution of this prospectus supplement and the accompanying prospectus in any jurisdiction, other than in the United States. Persons outside the United States who come into possession of this prospectus supplement and the accompanying prospectus must inform themselves about, and observe any restrictions relating to, the offering of the common stock and the distribution of this prospectus supplement and the accompanying prospectus outside the United States. This prospectus supplement and the accompanying prospectus do not constitute, and may not be used in connection with, an offer to sell, or a solicitation of an offer to buy, any securities offered by this prospectus supplement and the accompanying prospectus by any person in any jurisdiction in which it is unlawful for such person to make such an offer or solicitation.

MARKET, INDUSTRY AND OTHER DATA

This prospectus supplement contains and incorporates by reference estimates, projections and other information concerning our industry, our business and the markets for our diagnostic tests, including data regarding the estimated size of those markets and their projected growth rates We obtained the industry, market and other data from our own internal estimates and research, as well as from independent industry publications and other publicly available information, including information from government agencies. Although we believe that these sources are reliable, we do not guarantee the accuracy or completeness of third-party information and we have not independently verified that information. Although we are not aware of any misstatements regarding the market and industry data presented in this prospectus and the documents incorporated herein by reference, estimates, forecasts, projections, market research or similar data is inherently subject to uncertainties and actual events or circumstances may differ materially from events and circumstances that are assumed in that data and are subject to change based on various factors, including those discussed under the heading “Risk Factors” in this prospectus supplement and under similar headings in the other documents that are incorporated by reference into this prospectus. Accordingly, investors should not place undue reliance on this information.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus supplement and the accompanying prospectus contain “forward-looking statements” that involve risks and uncertainties. Our actual results could differ materially from those discussed in the forward-looking statements. The statements contained in this prospectus supplement that are not purely historical are forward-looking statements within the meaning of Section 27A of the Securities Act, and Section 21E of the Exchange Act. Forward-looking statements are often identified by the use of words such as, but not limited to, “anticipate,” “believe,” “can,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “plan,” “project,” “seek,” “should,” “strategy,” “target,” “will,” “would” and similar expressions or variations intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words. These statements are based on the beliefs and assumptions of our management based on information currently available to management but such forward-looking statements are subject to risks, uncertainties and other important factors that could cause actual results and the timing of certain events to differ materially from future results expressed or implied by such forward-looking statements. These important factors include but are not limited to those discussed under the “Risk Factors” sections of this prospectus supplement, the accompanying prospectus, and our most recent Annual Report on Form 10-K, as updated by our subsequent filings under the Exchange Act, and the other periodic reports and other filings that we file from time to time with the SEC, each of which is incorporated by reference in this prospectus supplement in their entirety. Accordingly, we cannot guarantee that we actually will achieve the plans, intentions or expectations expressed in our forward-looking statements and you should not place undue reliance on our forward-looking statements. Furthermore, such forward-looking statements speak only as of the date of this prospectus supplement. Except as required by law, we undertake no obligation to update any forward-looking statements to reflect events or circumstances after the date of such statements.

Please consider our forward-looking statements in light of those risks as you read this prospectus supplement and the accompanying prospectus. It is not possible for our management to predict all risks, nor can we assess the impact of all factors 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 may make. Given these uncertainties, you should not place undue reliance on these forward-looking statements.

You should not assume that the information contained in this prospectus supplement and the accompanying prospectus is accurate as of any date other than as of the date of this prospectus supplement or the accompanying prospectus, as the case may be, or that any information incorporated by reference into this prospectus is accurate as of any date other than the date of the document so incorporated by reference. Except as required by law, we assume no obligation to update these forward-looking statements publicly, or to update the reasons actual results could differ materially from those anticipated in these forward-looking statements, even if new information becomes available in the future. Thus, you should not assume that our silence over time means that actual events are bearing out as expressed or implied in such forward-looking statements.

If one or more of these or other risks or uncertainties materializes, or if our underlying assumptions prove to be incorrect, actual results may vary materially from what we anticipate. All subsequent written and oral forward-looking statements attributable to us or individuals acting on our behalf are expressly qualified in their entirety by this note. Before purchasing any shares of common stock, you should consider carefully all of the factors set forth or referred to in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference that could cause actual results to differ.

Overview

We are a molecular diagnostics company focused on developing and commercializing proprietary laboratory-developed tests, or LDTs, to serve unmet medical needs across the cancer care continuum. Our mission is to provide actionable information to physicians and patients at critical decision points to optimize diagnosis and treatment decisions, improve patient outcomes, and reduce overall cost of care. We have prioritized lung cancer as our first indication. Lung cancer remains the leading cause of cancer death in the United States, despite the availability of molecular testing and novel therapies to treat patients.

Our first commercial diagnostic test is a proprietary treatment stratification test called DetermaRx™ that identifies which patients with early stage non-small cell lung cancer may benefit from chemotherapy, resulting in a significantly higher, five-year survival rate. We are also developing multi-gene molecular, laboratory-developed diagnostic tests that we have branded as DetermaIO™. DetermaIO™ is a proprietary gene expression assay with promising data supporting its potential to help identify patients likely to respond to checkpoint inhibitor drugs. This new class of drugs modulate the immune response and show activity in multiple solid tumor types including non-small cell lung cancer, and triple negative breast cancer. DetermaIO™ is presently available for research use but one of our goals is to complete development of that assay and to make it available for clinical use later this year. We also perform assay development and clinical testing services for pharmaceutical and biotechnology companies.

We recently added to our diagnostic test pipeline DetermaCNI™, a patented, blood-based test for immunotherapy monitoring. DetermaCNI was developed by Chronix Biomedical, Inc., which we acquired through a merger in April 2021. We plan to make the CNI Monitor test available initially as a research tool.

Other tests in our development pipeline include DetermaTx™, a test that we are targeting for commercial launch later this year and that is intended to compliment DetermaIO™ by assessing the mutational status of a tumor to help identify the appropriate targeted therapy. We also plan to initiate the development of DetermaMx™ as a blood based test to monitor cancer patients for recurrence of their disease.

Corporate Information

We were incorporated in 2009 in the state of California. Our principal executive offices are located at 15 Cushing, Irvine, California 92618. Our telephone number is (949) 409-7600. Our website is www.oncocyte.com. Information contained on, or that can be accessed through, our website, is not, and shall not be deemed to be, incorporated in this prospectus supplement or considered a part thereof.

Implications of Being an Emerging Growth Company

We qualify as an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. As an emerging growth company, we intend to take advantage of specified reduced disclosure and other requirements that are otherwise applicable generally to public companies. These provisions include:

	●	allowance to provide only two years of audited financial statements in addition to any required unaudited interim financial statements with correspondingly reduced “Management’s Discussion and Analysis of Financial Condition and Results of Operations” disclosure;

	●	reduced disclosure about our executive compensation arrangements;

	●	exemption from the requirements of holding non-binding advisory votes on executive compensation or golden parachute arrangements; and

	●	exemption from the auditor attestation requirement in the assessment of our internal control over financial reporting.

We may take advantage of these provisions for up to five years or such earlier time that we are no longer an emerging growth company. We would cease to be an emerging growth company on the date that is the earliest of: (i) the last day of the fiscal year in which we have total annual gross revenues of $1.07 billion or more; (ii) the last day of our fiscal year following the fifth anniversary of the date of the completion of our initial public offering; (iii) the date on which we have issued more than $1.07 billion in nonconvertible debt during the previous three years; or (iv) the date on which we are deemed to be a large accelerated filer under the rules of the SEC. We have taken advantage of reduced reporting requirements in this prospectus supplement. Accordingly, the information contained herein may be different than the information you receive from other public companies in which you have beneficial ownership.

Manner of offering		“At-the-market offering” that may be made from time to time through our sales agent, BTIG. See “Plan of Distribution” on page S-8 of this prospectus supplement.

Use of proceeds		We currently intend to use the net proceeds, if any, from this offering to promote commercialization of DetermaRx,™ including sales and marketing efforts and by conducting additional clinical studies to support clinical adoption of the test; to complete development of DetermaIO™; for development of other future tests in our pipeline, including DetermaCNI™, DetermaTx™, and DetermaMx™ and any others that we may acquire. We recently acquired Chronix Biomedical, Inc., or Chronix, under the terms of an Agreement and Plan of Merger (the “Chronix Merger Agreement”) and we may use net proceeds to pay obligations of Chronix and to make certain future milestone payments to former Chronix shareholders that may become payable as additional merger consideration under the Chronix Merger Agreement. We may use net proceeds, if any, from this offering to pay all or a portion of the $6.0 million of additional merger consideration that may become payable to former shareholders of Insight Genetics, Inc., or Insight, under the terms of an Agreement and Plan of Merger if the applicable milestones requiring such payments are met. We may use net proceeds, if any, from this offering, to invest in or acquire other businesses or technologies that we believe are complementary to our own, although we have no binding agreements with respect to any acquisitions as of the date of this prospectus supplement other than the merger agreements with Insight and Chronix. See “Use of Proceeds” beginning on page S-6. Net proceeds, if any, from this offering not used for the foregoing purposes may be used for general corporate and working capital purposes.

Risk factors		Investing in our common stock involves a high degree of risk.

RISK FACTORS

Investing in our securities involves a high degree of risk and uncertainty. Before making an investment decision with respect to our securities, we urge you to carefully consider the risks, uncertainties and assumptions described in this prospectus, the applicable prospectus supplement and the documents incorporated by reference herein and therein, including the risks described in Part I, Item 1A. Risk Factors of our most recent Annual Report on Form 10-K and in our subsequent Quarterly Reports on Form 10-Q filed with the SEC. You should also refer to the other information contained in this prospectus and the applicable prospectus supplement and the documents incorporated by reference into this prospectus and the applicable prospectus supplement, including our financial statements and the notes to those statements and the information set forth in the section entitled “Special Note Regarding Forward-Looking Statements.”

If one or more of the adverse events relevant to those risks and uncertainties actually occurs, our business, financial condition, results of operations, cash flows or prospects could be materially adversely affected. This could cause the trading price of our securities to decline, and you could lose all or part of your investment. Additional risks and uncertainties not presently known to us or that we currently deem immaterial also may have similar adverse effects on us.

You should also refer to the other information contained in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference into this prospectus supplement and the accompanying prospectus, including our financial statements and the notes to those statements and the information set forth in the section entitled “Special Note Regarding Forward-Looking Statements.”

Risks Related to this Offering

We have broad discretion in the use of our available cash and other sources of funding, including the net proceeds we may receive from this offering, if any, and may not use them effectively.

Our management has broad discretion in the use of our available cash and other sources of funding, including the net proceeds we receive in this offering, and could spend those resources for purposes other than those described in the “Use of Proceeds” portion of this prospectus supplement, and in ways that do not improve our results of operations or enhance the value of our common stock. The failure by our management to apply these funds effectively could result in financial losses that could have a material adverse effect on our business, cause the price of our common stock to decline and delay the development of our product candidates. Pending use in our operations, we may invest our available cash, including the net proceeds we receive in this offering, in a manner that does not produce income or that loses value.

If you purchase shares of our common stock sold in this offering, you may experience immediate and substantial dilution in the net tangible book value of your shares. In addition, we may issue additional equity or convertible debt securities in the future, which may result in additional dilution to investors.

The price per share of our common stock being offered may be higher than the net tangible book value per share of our outstanding common stock prior to this offering. Assuming that an aggregate of 10,504,202 shares of our common stock are sold at a price of $4.76 per share, the last reported sale price of our common stock on the Nasdaq on June 8, 2021, for aggregate gross proceeds of $50,000,000 before deducting commissions and estimated offering expenses payable by us, new investors in this offering will incur immediate dilution of $3.78 per share. For a more detailed discussion of the foregoing, see the section entitled “Dilution” on page S-7 of this prospectus supplement. To the extent outstanding stock options or warrants are exercised, there will be further dilution to new investors.

Resales of our common stock in the public market during this offering by our stockholders may cause the market price of our common stock to fall.

We may issue common stock from time to time in connection with this offering. This issuance from time to time of these new shares of our common stock, or our ability to issue these shares of common stock in this offering, could result in resales of our common stock by our current stockholders concerned about the potential dilution of their holdings. In turn, these resales could have the effect of depressing the market price for our common stock.

S-5

The actual number of shares we will issue under the sales agreement, at any one time or in total, is uncertain.

Subject to certain limitations in the sales agreement and compliance with applicable law, we have the discretion to deliver placement notices to BTIG at any time throughout the term of the sales agreement. The number of shares that are sold by BTIG after our delivering a placement notice will fluctuate based on the market price of the common stock during the sales period and limits we set with BTIG.

The shares of common stock offered under this prospectus supplement and the accompanying prospectus may be sold in “at-the-market” offerings, and investors who buy shares at different times will likely pay different prices.

Investors who purchase shares under this prospectus supplement and the accompanying prospectus 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 declines in the value of their shares as a result of share sales made at prices lower than the prices they paid.

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

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

USE OF PROCEEDS

We may issue and sell shares of our common stock having aggregate gross proceeds of up to $50,000,000 from time to time under this prospectus supplement and the accompanying prospectus. Because there is no minimum offering amount required as a condition to close this offering, the actual total offering amount, commissions and proceeds to us, if any, are not determinable at this time. The amount of proceeds from this offering will depend upon the number of shares of our common stock sold and the market price at which they are sold. There can be no assurance that we will be able to sell any shares under or fully utilize the sales agreement as a source of financing.

We currently intend to use the net proceeds, if any, from this offering to promote commercialization of DetermaRx,™ including sales and marketing efforts and by conducting additional clinical studies to support clinical adoption of the test; to complete development of DetermaIO™; for development of other future tests in our pipeline, including DetermaCNI™, DetermaTx™, and DetermaMx™ and any others that we may acquire. We recently acquired Chronix under the terms of the Chronix Merger Agreement and we may use net proceeds to pay obligations of Chronix and to make certain future milestone payments to former Chronix shareholders that may become payable as additional merger consideration under the Chronix Merger Agreement. We may use net proceeds to pay all or a portion of the $6 million of additional merger consideration that may become payable to former shareholders of Insight under the terms of a merger agreement if the applicable milestones requiring such payments are met. Net proceeds not used for the foregoing purposes may be used for general corporate and working capital purposes.

S-6

In addition, as part of our strategic business plan, we regularly research and evaluate the acquisition of businesses or technologies that we believe are complementary to our own product development and commercialization efforts. Consequently, we may use net proceeds from the offering to invest in or acquire businesses or assets, including also licensing rights to use technologies. Our strategic initiatives are currently focused on, and we are actively evaluating, businesses or technologies that we believe will allow us to acquire additional cancer tests for development. However, we have no binding agreements with respect to any such potential future acquisitions in place as of the date of this prospectus supplement.

We have not determined the exact amounts we plan to spend on any of the purposes listed above or the timing of these expenditures. The amounts and timing of our actual expenditures may vary significantly depending on numerous factors, including the actual net proceeds from this offering. Accordingly, you will be relying on the judgment of our management with regard to the use of these net proceeds, and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used appropriately. Our board of directors believes the flexibility in application of the net proceeds is prudent.

Pending application of the net proceeds as described above, we may temporarily invest the net proceeds in a variety of capital preservation instruments, including short-term, investment-grade, interest-bearing instruments and U.S. government securities.

DIVIDEND POLICY

We have never paid cash dividends on our common stock and we do not anticipate paying cash dividends in the foreseeable future, but intend to retain our capital resources for reinvestment in our business. Under an existing credit agreement with Silicon Valley Bank, we have agreed not to pay dividends or to make any distributions or to redeem to repurchase any capital stock without Silicon Valley Bank’s prior written consent. Any future determination to pay cash dividends will be at the discretion of our board of directors and will be dependent upon the repayment of the loans from Silicon Valley Bank, our financial condition, results of operations, capital requirements and other factors as our board of directors deems relevant.

DILUTION

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

Our net tangible book value as of March 31, 2021 was approximately $49.4 million, or $0.56 per share of our common stock. Our net tangible book value is the amount of our total tangible assets less our total liabilities. Net tangible book value per share represents net tangible book value divided by the total number of shares of our common stock outstanding as of March 31, 2021. Dilution with respect to net tangible book value per share represents the difference between the amount per share paid by purchasers of shares of common stock in this offering and the net tangible book value per share of our common stock immediately after this offering.

After giving effect to the issuance and sale of our common stock in the aggregate amount of $50,000,000 in this offering, at an assumed offering price of $4.76 per share, the last reported sale price of our common stock on the Nasdaq on June 8, 2021, and after deducting estimated offering commissions and estimated offering expenses payable by us, our as adjusted net tangible book value as of March 31, 2021 would have been approximately $97.8 million, or $0.98 per share. This represents an immediate increase in as adjusted net tangible book value of $0.42 per share to existing stockholders and an immediate dilution of $3.78 per share to new investors purchasing securities in this offering.

The following table illustrates this per share dilution:

Assumed offering price per share			$	4.76
Net tangible book value per share as of March 31, 2021	$	0.56
Increase in net tangible book value per share attributable to this offering		0.42
As adjusted net tangible book value per share as at March 31, 2021, after giving effect to this offering				0.98
Dilution per share to new investors participating in this offering			$	3.78

S-7

The above discussion and table assumes for illustrative purposes that an aggregate of 10,504,202 shares of our common stock are sold at a price of $4.76 per share, the last reported sale price of our common stock on the Nasdaq on June 8, 2021, for aggregate gross proceeds of approximately $50,000,000. The shares sold in this offering, if any, will be sold from time to time at various prices. An increase of $0.50 per share in the price at which the shares are sold from the assumed offering price of $4.76 per share shown in the table above, assuming all of our common stock in the aggregate amount of $50,000,000 is sold at that price, would increase our adjusted net tangible book value per share after the offering by $0.01 per share and would increase the dilution in net tangible book value per share to new investors in this offering by $0.49 per share, after deducting estimated offering expenses and commissions payable by us. A decrease of $0.50 per share in the price at which the shares are sold from the assumed offering price of $4.76 per share shown in the table above, assuming all of our common stock in the aggregate amount of $50,000,000 is sold at that price, would decrease our adjusted net tangible book value per share after the offering by $0.01 per share and would decrease the dilution in net tangible book value per share to new investors in this offering by $0.49 per share, after deducting estimated offering expenses and commissions payable by us. This information is supplied for illustrative purposes only.

The information above is based on 88,914,128 shares of our common stock outstanding as of March 31, 2021, and excludes:

	●	1,128,000 shares of our common stock issuable upon exercise of options outstanding under our 2010 Stock Option Plan as of March 31, 2021, with a weighted-average exercise price of $3.65 per share;

To the extent that any outstanding options or warrants are exercised, new options, restricted stock or restricted stock units are issued under our Equity Incentive Plan or we otherwise issue additional shares of common stock or other equity or convertible debt securities in the future, you will experience further dilution.

PLAN OF DISTRIBUTION

We have entered into the sales agreement with BTIG under which we may issue and sell shares of our common stock having an aggregate offering price of up to $50,000,000 from time to time through BTIG, acting as our sales agent. Sales of our common stock, if any, under this prospectus may be made in negotiated transactions, or by 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 Nasdaq or sales made to or through a market maker other than on an exchange.

Each time that we wish to issue and sell shares of our common stock under the sales agreement, we will provide BTIG with a placement notice describing the amount of shares to be sold, the time period during which sales are requested to be made, any limitation on the amount of shares of common stock that may be sold in any single day, any minimum price below which sales may not be made or any minimum price requested for sales in a given time period and any other instructions relevant to such requested sales. Upon receipt of a placement notice, BTIG, acting as our sales agent, will use commercially reasonable efforts, consistent with its normal trading and sales practices and applicable state and federal laws, rules and regulations and the rules of the Nasdaq, to sell shares of our common stock under the terms and subject to the conditions of the placement notice and the sales agreement. We or BTIG may suspend the offering of common stock pursuant to a placement notice upon notice and subject to other conditions. BTIG, in its sole discretion, may decline to accept any placement notice.

BTIG will provide written confirmation to us no later than the opening of the trading day on the Nasdaq following the trading day on which shares of our common stock are sold through BTIG as sales agent under the sales agreement. Each confirmation will include the number of shares sold on the preceding day, the net proceeds to us and the commissions payable by us to BTIG in connection with the sales.

S-8

Settlement for sales of common stock under the sales agreement will occur on the second trading day following the date on which such sales are made (or on such other date as is industry practice for regular-way trading), unless otherwise specified in the applicable placement notice, in return for payment of the net proceeds to us. There are no arrangements to place any of the proceeds of this offering in an escrow, trust or similar account. Sales of our 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 BTIG may agree upon.

We will pay BTIG commissions for its services in acting as our sales agent in the sale of our common stock pursuant to the sales agreement. BTIG will be entitled to compensation at a fixed commission rate of 3.0% of the gross proceeds from the sale of our common stock on our behalf pursuant to the sales agreement. We also have agreed to reimburse BTIG for its reasonable out-of-pocket expenses, including the fees and disbursements of BTIG’s counsel, incurred in connection with entering into the sales agreement, in an amount not to exceed $50,000, and fees and disbursements of BTIG’s counsel on a quarterly basis not to exceed $7,500.

We estimate that the total expenses for this offering, excluding compensation payable to BTIG and certain expenses reimbursable to BTIG under the terms of the sales agreement, will be approximately $185,000. The remaining sales proceeds, after deducting any expenses payable by us and any transaction fees imposed by any governmental, regulatory, or self-regulatory organization in connection with the sales, will equal our net proceeds for the sale of such common stock.

Because there are no minimum sale requirements as a condition to this offering, the actual total public offering price, commissions and net proceeds to us, if any, are not determinable at this time. The actual dollar amount and number of shares of common stock we sell through this prospectus supplement will be dependent, among other things, on market conditions and our capital raising requirements.

We will report at least quarterly the number of shares of common stock sold through BTIG under the sales agreement, the net proceeds to us and the compensation paid by us to BTIG in connection with the sales of common stock.

In connection with the sale of the common stock on our behalf, BTIG will be deemed to be an “underwriter” within the meaning of the Securities Act, and the compensation of BTIG will be deemed to be underwriting commissions or discounts. We have agreed to provide indemnification and contribution to BTIG against certain civil liabilities, including liabilities under the Securities Act or the Exchange Act.

BTIG will not engage in any market making activities involving our common stock while the offering is ongoing under this prospectus supplement if such activity would be prohibited under Regulation M or other anti-manipulation rules under the Securities Act. As our sales agent, BTIG will not engage in any transactions that stabilizes our common stock.

The offering 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 (ii) termination of the sales agreement as permitted therein. We may terminate the sales agreement in our sole discretion at any time by giving 10 days’ prior notice to BTIG. BTIG may terminate the sales agreement under the circumstances specified in the sales agreement and in its sole discretion at any time by giving 10 days’ prior notice to us.

The sales agreement has been filed as an exhibit to a current report on Form 8-K that we filed with the SEC in connection with this offering and is incorporated into this prospectus supplement by reference.

BTIG and/or its affiliates may in the future provide, various investment banking and other financial services for us, for which services may in the future receive customary fees.

ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement on Form S-3 that we filed with the Securities and Exchange Commission, or the SEC, under the Securities Act of 1933, as amended, of the Securities Act, using a “shelf” registration process. Under this process, we may, from time to time, offer and sell, either individually or in combination, in one or more offerings, up to a total dollar amount of $240.0 million of any of the securities described in this prospectus.

This prospectus provides a general description of the securities we may offer. Each time we offer and sell securities under this prospectus, we will, to the extent required by law, provide a prospectus supplement that will contain specific information about the terms of that offering. We may also authorize one or more free writing prospectuses to be provided to you that may contain material information relating to a particular offering. The prospectus supplement and any related free writing prospectus may also add, update or change information contained in this prospectus or in any documents that we have incorporated by reference into this prospectus with respect to that offering. To the extent there is a conflict between any statement contained in this prospectus, any applicable prospectus supplement, any related free writing prospectus or any document incorporated by reference into this prospectus, the statement in the document having the later date modifies or supersedes the earlier statement.

The information appearing in this prospectus, any applicable prospectus supplement or any related free writing prospectus is accurate only as of the date on the front of the document, and 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, any applicable prospectus supplement or any related free writing prospectus, or the time of any sale of a security. Our business, financial condition, results of operations and prospects may have changed since those dates.

You should rely only on the information contained in, or incorporated by reference into, this prospectus and any applicable prospectus supplement, or the information contained in any free writing prospectus we have authorized for use in connection with a specific offering. We have not authorized anyone to provide you with different or additional information. This prospectus is neither an offer to sell nor a solicitation of an offer to buy any securities other than those registered by this prospectus, nor is it an offer to sell or a solicitation of an offer to buy securities where an offer or solicitation would be unlawful.

As permitted by SEC rules and regulations, the registration statement of which this prospectus forms a part includes additional information not contained in this prospectus. This prospectus also contains summaries of certain provisions of the documents described herein, but all summaries are qualified in their entirety by reference to the actual documents. You may read the registration statement and the other reports we file with the SEC, and you may obtain copies of the actual documents summarized herein (if and when filed with the SEC), at the SEC’s website. See “Where You Can Find More Information.”

The representations, warranties and covenants made by us in any agreement that is filed as an exhibit to any document incorporated by reference into this prospectus were made solely for the benefit of the parties to such agreement, including for the purpose of allocating risks among such parties, and should not be deemed to be a representation, warranty or covenant to you. Moreover, such representations, warranties or covenants do not purport to be accurate as of any date other than when made. Accordingly, such representations, warranties and covenants should not be relied on as accurately representing the current state of our affairs.

MARKET, INDUSTRY AND OTHER DATA

This prospectus contains estimates, projections and other information concerning our industry, our business and the markets for our diagnostic tests, including data regarding the estimated size of those markets and their projected growth rates, as well as market research, estimates and forecasts prepared by our management. We obtained the industry, market and other data throughout this prospectus from our own internal estimates and research, as well as from publicly available information, industry publications and research, surveys and studies conducted by third-parties, including governmental agencies.

Information that is based on estimates, forecasts, projections, market research or similar methodologies is inherently subject to uncertainties and actual events or circumstances may differ materially from events and circumstances that are assumed in this information based on various factors, including those discussed under the heading “Risk Factors” and elsewhere in this prospectus and in the documents incorporated by reference. We believe that these sources and estimates are reliable but have not independently verified them and cannot guarantee their accuracy or completeness. We caution you not to give undue weight to such projections, assumptions and estimates.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus and the information incorporated by reference contain “forward-looking statements” that involve risks and uncertainties. Our actual results could differ materially from those discussed in the forward-looking statements. All statements that are not purely historical are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”) and Section 21E of the Securities Exchange Act of 1934, as amended, (the “Exchange Act”). Forward-looking statements are often identified by the use of words such as, but not limited to, “anticipate,” “believe,” “can,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “plan,” “project,” “seek,” “should,” “strategy,” “target,” “will,” “would” and similar expressions or variations intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words. These statements are based on the beliefs and assumptions of our management based on information currently available to management. Such forward-looking statements are subject to risks, uncertainties and other important factors that could cause actual results and the timing of certain events to differ materially from future results expressed or implied by such forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to, those identified below and those discussed in the Risk Factors sections and elsewhere in our Annual Reports on Form 10-K and in our Quarterly Reports on Form 10-Q and in the other periodic reports and other filings that we file from time to time with the SEC. These factors and the other cautionary statements made in this prospectus and the documents incorporated by reference herein should be read as being applicable to all related forward-looking statements whenever they appear in this prospectus. The disclosure in this prospectus, including any forward-looking statement, speaks only as of its date, the date of this prospectus, or the date of any document incorporated by reference into this prospectus, as applicable. We disclaim any intention or obligation to update or revise any forward-looking statement, whether as a result of new information, future events or otherwise, except as required by law.

The forward-looking statements in this prospectus and the information incorporated by reference include, among other things, statements about:

	●	the timing and potential achievement of future milestones;

	●	the timing and our ability to obtain and maintain coverage and reimbursements from the Centers for Medicare and Medicaid Services and other third-party payers;

	●	our plans to pursue research and development of laboratory test candidates;

	●	the potential commercialization of our laboratory tests currently in development;

	●	the timing and success of future clinical trials and the period during which the results of the clinical trials will become available;

	●	the potential receipt of revenue from future sales of our current laboratory tests or tests in development;

	●	our assumptions regarding obtaining reimbursement and reimbursement rates;

	●	our estimates regarding future orders of laboratory tests and our ability to perform a projected number of tests;

	●	our estimates and assumptions around patient populations, market size and price points for reimbursement for our laboratory tests

	●	our estimates regarding future revenues and operating expenses, and future capital requirements;

	●	our intellectual property position;

	●	the impact of government laws and regulations;

	●	our ability to expand our operations geographically in the United States and abroad;

	●	the impact of the Covid-19 pandemic on our operations and demand for our diagnostic tests; and

	●	our competitive position;

Please consider our forward-looking statements in light of those risks as you read this prospectus supplement, and the accompanying prospectus and the information incorporated into each by reference. It is not possible for our management to predict all risks, nor can we assess the impact of all factors 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 may make. Given these uncertainties, you should not place undue reliance on these forward-looking statements.

If one or more of these or other risks or uncertainties materializes, or if our underlying assumptions prove to be incorrect, actual results may vary materially from what we anticipate. All subsequent written and oral forward-looking statements attributable to us or individuals acting on our behalf are expressly qualified in their entirety by this note. Before purchasing any shares of common stock, you should consider carefully all of the risk factors set forth or referred to in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference that could cause actual results to differ.

SUMMARY

This summary highlights selected information contained elsewhere in this prospectus. This summary is not complete and does not contain all the information you should consider before investing in our securities pursuant to this prospectus. Before making an investment decision, please carefully read this entire prospectus and the documents incorporated by reference into this prospectus, including the “Risk Factors” section of our most recent Annual Report on Form 10-K and any subsequent Quarterly Reports on Form 10-Q and our financial statements and the related notes incorporated by reference into this prospectus. In this prospectus, unless the context otherwise requires, the terms “OncoCyte,” “we,” “us” or “our” refer to OncoCyte Corporation.

Overview

We are a molecular diagnostics company focused on developing and commercializing proprietary laboratory-developed tests (“LDTs”) to serve unmet medical needs across the cancer care continuum. Our mission is to provide actionable information to physicians and patients at critical decision points to optimize diagnosis and treatment decisions, improve patient outcomes, and reduce overall cost of care. We have prioritized lung cancer as our first indication. Lung cancer remains the leading cause of cancer death in the United States, despite the availability of molecular testing and novel therapies to treat patients.

Our first commercial diagnostic test is a proprietary treatment stratification test called DetermaRx™ that identifies which patients with early stage non-small cell lung cancer may benefit from chemotherapy, resulting in a significantly higher, five-year survival rate. We are also developing multi-gene molecular, laboratory-developed diagnostic tests that we have branded as DetermaIO™. DetermaIO™ is a proprietary gene expression assay with promising data supporting its potential to help identify patients likely to respond to checkpoint inhibitor drugs. This new class of drugs modulate the immune response and show activity in multiple solid tumor types including non-small cell lung cancer (NSCLC), and triple negative breast cancer (TNBC). DetermaIO™ is presently available for research use but one of our goals is to complete development of that assay and to make it available for clinical use later this year. We also perform assay development and clinical testing services for pharmaceutical and biotechnology companies.

We recently added to our diagnostic test pipeline DetermaCNI™, a patented, blood-based test for immunotherapy monitoring. DetermaCNI™ was developed by Chronix Biomedical, Inc., which we acquired through a merger in April 2021. We plan to make DetermaCNI™ available initially as a research tool.

Corporate Information

RISK FACTORS

USE OF PROCEEDS

Except as described in any prospectus supplement in connection with a specific offering, we intend to use the net proceeds from our sale of the securities offered under this prospectus for working capital and general corporate purposes. The principal purposes for which we intend to use the net proceeds from a specific offering and the approximate amounts intended to be used for each such purpose will be set forth in the prospectus supplement relating to that offering.

DIVIDEND POLICY

We have never paid cash dividends on our capital stock and we do not anticipate paying cash dividends in the foreseeable future as we intend to retain our capital resources for reinvestment in our business. Under an existing credit agreement with Silicon Valley Bank, we have agreed not to pay dividends or to make any distributions or to redeem to repurchase any capital stock without Silicon Valley Bank’s prior written consent. Any future determination to pay cash dividends will be at the discretion of our board of directors and will be dependent upon the repayment of the loans from Silicon Valley Bank, our financial condition, results of operations, capital requirements and other factors as our board of directors deems relevant.

SECURITIES THAT MAY BE OFFERED

We may offer shares of common stock, shares of preferred stock, warrants, units consisting of a combination of the foregoing securities or any other combination of the foregoing. We may offer up to $240.0 million of securities under this prospectus. The prices and terms of any offering will be determined by market conditions at the time of offering. We may issue preferred stock that is exchangeable for or convertible into common stock or any of the other securities that may be sold under this prospectus. Each time we offer securities under this prospectus, we will provide offerees with a prospectus supplement that will describe the specific amounts, prices and other important terms of the securities being offered.

The summaries below provide a general description of the securities we may offer and are not intended to be complete. The particular terms of any security will be described in the applicable prospectus supplement.

DESCRIPTION OF CAPITAL STOCK

The following description of our capital stock, together with any additional information we include in any applicable prospectus supplement, documents incorporated by reference or any related free writing prospectus, summarizes the material terms and provisions of our common stock that we may offer, and the preferred stock that we may offer, under this prospectus. We will describe the particular terms of any class or series of these securities in more detail in the applicable prospectus supplement. The description of our capital stock below is summarized from, and qualified in its entirety by reference to, our Articles of Incorporation and our Bylaws, in each case, as amended and as in effect on the date of this prospectus, each of which has been publicly filed with the SEC. Certain terms of our capital stock described below are also based on the California Corporations Code as in existence on the date of this prospectus, and may be affected by future amendments to such code.

General

Our Articles of Incorporation currently authorizes the issuance of up to 150,000,000 shares of common stock, no par value, and up to 5,000,000 shares of preferred stock, no par value. As of May 10, 2021, there were 89,833,751 shares of common stock outstanding.

Common Stock

Each holder of record of common stock is entitled to one vote for each outstanding share owned, on every matter properly submitted to the shareholders for their vote.

Subject to any dividend rights of holders of any of the preferred stock that we may issue from time to time, holders of common stock are entitled to any dividend declared by our board of directors out of funds legally available for that purpose. We have never paid cash dividends on our capital stock and we do not anticipate paying cash dividends in the foreseeable future as we intend to retain our capital resources for reinvestment in our business.

Subject to the prior payment of any liquidation preference to holders of any preferred stock that we may issue from time to time, holders of common stock are entitled to receive on a pro rata basis all of our remaining assets available for distribution to the holders of common stock in the event of the liquidation, dissolution, or winding up of our operations. Holders of our common stock do not have any preemptive, subscription, or redemption rights. All of the outstanding shares of our common stock are fully paid and non-assessable. The shares of common stock offered under this prospectus or upon the conversion of any preferred stock or exercise of any warrants offered pursuant to this prospectus, when paid for and issued in accordance with the applicable definitive documents under which they are to be issued, will also be fully paid and non-assessable.

Our common stock is listed on the Nasdaq under the symbol “OCX.”

The transfer agent and registrar for our common stock is American Stock Transfer & Trust Company, LLC, 6201 15th Avenue, Brooklyn, New York 11219.

Preferred Stock

We may issue preferred stock in one or more series, at any time, with such rights, preferences, privileges and restrictions as our board of directors may determine, all without further action of our shareholders. Any series of preferred stock which may be authorized by our board of directors in the future may be senior to and have greater rights and preferences than our common stock. There are no shares of preferred stock presently outstanding and we have no present plan, arrangement, or commitment to issue any preferred stock.

The rights, privileges, preferences and restrictions of any class or series of preferred stock may be subordinated to, pari passu with or senior to any of those of any present or future class or series of preferred stock or common stock. Our board of directors is also expressly authorized to increase or decrease the number of shares of any series, but subsequent to the issue of shares of that series the number of shares of the series may not be decreased below the number of such shares then outstanding. The issuance of preferred stock may have the effect of decreasing the market price of our common stock and may adversely affect the voting power of holders of our common stock and reduce the likelihood that holders of our common stock will receive dividend payments and payments upon liquidation. In addition, the issuance of preferred stock could have the effect of delaying, deferring or preventing a change in our control or other corporate action.

The particular terms of each class or series of preferred stock that we may offer under this prospectus, including redemption privileges, liquidation preferences, voting rights, dividend rights or conversion rights, will be more fully described in the applicable prospectus supplement relating to the preferred stock offered thereby. The applicable prospectus supplement will specify the terms of the class or series of preferred stock we may offer, including:

	●	the distinctive designation and the maximum number of shares in the class or series;

	●	the number of shares we are offering and the purchase price per share;

	●	the liquidation preference, if any;

	●	the terms on which dividends, if any, will be paid;

	●	the voting rights, if any;

	●	the terms and conditions, if any, on which the shares of the class or series shall be convertible into, or ex-changeable for, shares of any other class or series of authorized capital;

	●	the terms on which the shares may be redeemed, if at all;

	●	any listing of the preferred stock on any securities exchange or market;

	●	a discussion of any material or special U.S. federal income tax considerations applicable to the preferred stock; and

	●	any or all other preferences, rights, restrictions, including restrictions on transferability and qualifications of shares of the class or series.

DESCRIPTION OF WARRANTS

General

We may offer warrants for the purchase of shares of common stock, shares of preferred stock or the other securities registered hereby, in one or more series. We may issue the warrants by themselves or together with common stock, preferred stock, other warrants or units, and the warrants may be attached to or separate from any offered securities. While the terms we have summarized below will apply generally to any warrants that we may offer under this prospectus, we will describe in particular the 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 by a prospectus supplement may differ from the terms described below.

We will file as an exhibit to the registration statement of which this prospectus forms a part, or will incorporate by reference from another report that we file with the SEC, the form of warrant or warrant agreement, which may include a form of warrant certificate, as applicable, that describes the terms of the particular series of warrants we may offer before the issuance of the related series of warrants. We may issue the warrants under a warrant agreement that we will enter into with a warrant agent to be selected by us. The warrant agent will act solely as our agent in connection with the warrants and will not assume any obligation or relationship of agency or trust for or with any registered holders of warrants or beneficial owners of warrants. The following summary of material provisions of the warrants and warrant agreements are subject to, and qualified in their entirety by reference to, all the provisions of the form of warrant or warrant agreement and warrant certificate applicable to a particular series of warrants. We urge you to read the applicable prospectus supplement and any related free writing prospectus, as well as the complete form of warrant or the warrant agreement and warrant certificate, as applicable, that contain the terms of the warrants.

The particular terms of any issue of warrants will be described in the prospectus supplement relating to the issue. Those terms may include:

	●	the title of such warrants;

	●	the aggregate number of such warrants;

	●	the price or prices at which such warrants will be issued;

	●	the currency or currencies (including composite currencies) in which the price of such warrants may be payable;

	●	the terms of the securities purchasable upon exercise of such warrants and the procedures and conditions relating to the exercise of such warrants;

	●	the price at which the securities purchasable upon exercise of such warrants may be purchased;

	●	the date on which the right to exercise such warrants will commence and the date on which such right shall expire;

	●	any provisions for adjustment of the number or amount of securities receivable upon exercise of the warrants or the exercise price of the warrants;

	●	if applicable, the minimum or maximum amount of such warrants that may be exercised at any one time;

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

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

	●	information with respect to book-entry procedures, if any;

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

	●	U.S. federal income tax consequences of holding or exercising the warrants, if material; and

	●	any other terms of such warrants, including terms, procedures and limitations relating to the exchange or exercise of such warrants.

Each warrant will entitle its holder to purchase the number of securities at the exercise price set forth in, or calculable as set forth in, the applicable prospectus supplement. The warrants may be exercised as set forth in the prospectus supplement relating to the warrants offered. Unless we otherwise specify in the applicable prospectus supplement, warrants may be exercised at any time up to the close of business on the expiration date set forth in the prospectus supplement relating to the warrants offered thereby. After the close of business on the expiration date, unexercised warrants will become void.

We will specify the place or places where, and the manner in which, warrants may be exercised in the form of warrant, warrant agreement or warrant certificate and applicable prospectus supplement. Upon receipt of payment and the warrant or warrant certificate, as applicable, properly completed and duly executed at the corporate trust office of any warrant agent, or any other office (including ours) indicated in the prospectus supplement, we will, as soon as practicable, issue and deliver the securities purchasable upon such exercise. If less than all of the warrants (or the warrants represented by such warrant certificate) are exercised, a new warrant or a new warrant certificate, as applicable, will be issued 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.

Prior to the exercise of any warrants to purchase common stock or preferred stock, holders of the warrants will not have any of the rights of holders of common stock or preferred stock purchasable upon exercise, including the right to vote or to receive any payments of dividends or payments upon our liquidation, dissolution or winding up on the common stock or preferred stock purchasable upon exercise, if any.

DESCRIPTION OF UNITS

The following description, together with the additional information we may include in any applicable prospectus supplement, 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 and any related free writing prospectus. The terms of any units offered by a prospectus supplement may differ from the terms described below.

We will file as an exhibit to the registration statement of which this prospectus forms a part, or will incorporate by reference from another report we file with the SEC, the form of unit agreement that describes the terms of the series of units we may offer under this prospectus, 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 supplement and any related free writing prospectus, as well as the complete unit agreement and any supplemental agreements that contain the terms of the units.

General

We may offer units comprised of any combination of our common stock, preferred stock, warrants or other units, in one or more series. 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 in the sections of this prospectus titled “Description of Capital Stock” and “Description of Warrants” will apply to each unit and to any common stock, preferred stock or warrant included in each unit, respectively.

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 and any unit agent (including any of its 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.

PLAN OF DISTRIBUTION

We may sell our securities directly to one or more investors. We may also sell our securities through agents designated from time to time or to or through underwriters or dealers. The applicable prospectus supplement and any related free writing prospectus will describe the terms of the offering of the securities, including, to the extent applicable:

	●	the name or names of any agents, underwriters or dealers;

	●	the purchase price of the securities being offered and the net 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 discounts or concessions allowed or re-allowed or paid to dealers; and

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

We may distribute our securities from time to time in one or more transactions at:

	●	a fixed price or prices, which may be changed from time to time;

	●	market prices prevailing at the time of sale;

	●	prices related to such prevailing market prices; or

	●	negotiated prices.

Agents

We may designate agents who agree to use their reasonable efforts to solicit purchases of our securities for the period of their appointment or to sell our securities on a continuing basis. We will name any agent involved in the offering and sale of securities and we will describe any fees or commissions we will pay the agent in the applicable prospectus supplement.

Underwriters

If we use underwriters for a sale of securities, the underwriters will acquire the securities for their own account. The underwriters may resell the securities in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. The obligations of the underwriters to purchase the securities will be subject to the conditions set forth in the applicable underwriting agreement. Subject to certain conditions, the underwriters will be obligated to purchase all the securities of the series offered if they purchase any of the securities of that series. We may change from time to time any public offering price and any discounts or concessions the underwriters allow or reallow or pay to dealers. We may use underwriters with whom we have a material relationship. We will name any underwriter involved in the offering and sale of securities, describe any discount or other compensation and describe the nature of any material relationship in any applicable prospectus supplement. Only underwriters we name in the prospectus supplement will be underwriters of the securities offered by that prospectus supplement.

We may have agreements with the agents and underwriters to indemnify them against specified civil liabilities related to offerings under this prospectus, including liabilities under the Securities Act, or contribution with respect to payments that the agents or underwriters may make with respect to these liabilities.

Underwriters, dealers and agents that participate in the distribution of the securities may be underwriters as defined in the Securities Act, and any discounts or commissions they receive from us and any profit on their resale of the securities may be treated as underwriting discounts and commissions under the Securities Act. We will identify in the applicable prospectus supplement any underwriters, dealers or agents and will describe their compensation. We may have agreements with the underwriters, dealers and agents to indemnify them against specified civil liabilities related to offerings under this prospectus, including liabilities under the Securities Act, or contribution with respect to payments that the agents or underwriters may make with respect to these liabilities. Underwriters, dealers and agents may engage in transactions with or perform services for us in the ordinary course of their businesses.

Trading Markets and Listing of 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 currently listed on the Nasdaq. We may elect to list or qualify for trading any other class or series of securities on any securities exchange or other 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.

Stabilization Activities

Any underwriter may engage in overallotment, stabilizing transactions, short covering transactions and penalty bids in accordance with Regulation M under the Exchange Act of 1934, as amended, or 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.

Passive Market Making

Any underwriter who is a qualified market maker on the Nasdaq may engage in passive market making transactions in securities listed on the Nasdaq 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. A passive market maker must comply with applicable volume and price limitations and must be identified as a passive market maker. 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.

LEGAL MATTERS

Unless otherwise indicated in the applicable prospectus supplement, the validity of the any common stock, preferred stock, warrants or units offered under this prospectus and any supplement hereto will be passed upon for us by Ellenoff Grossman & Schole LLP, New York, New York.
