Overview

We are a biotech innovation company with a mission of prolonging life and enhancing its quality by improving the health of the immune system.

Our Business

We are developing biotechnologies specifically focused on improving the health of the immune system through immune reprogramming and monitoring. Our immune reprogramming technology is currently at the pre-clinical stage and designed to retrain the immune system to induce tolerance with an objective of addressing rejection of transplanted organs, autoimmune diseases, and allergies. Our immune monitoring technology is designed to provide a personalized comprehensive profile of the immune system and we plan to utilize it in our upcoming clinical trials to monitor subjects' immune response before, during and after drug administration.

Immune Reprogramming

The discovery of immunosuppressive (anti-rejection and monoclonal) drugs over 40 years ago has made possible life-saving organ transplantation procedures and blocking of unwanted immune responses in autoimmune diseases. However, immune suppression leads to significant undesirable side effects, such as increased susceptibility to life-threatening infections and cancers, because it indiscriminately and broadly suppresses immune function throughout the body. While the use of these drugs has been justifiable because they prevent or delay organ rejection, their use for treatment of autoimmune diseases and allergies may not be acceptable because of the above-mentioned side effects. Furthermore, transplanted organs often ultimately fail despite the use of immune suppression, and about 40% of transplanted organs survive no more than 5 years.

New, focused therapeutic approaches are needed to modulate only the small portion of immune cells that are involved in rejection of the transplanted organ, as this approach can be safer for patients than indiscriminate immune suppression. Such approaches are referred to as immune tolerance, and when therapeutically induced, may be safer for patients and also potentially allow long-term survival of transplanted tissues and organs.

In the late 1990s, academic research on these approaches was conducted at the Transplant Center in Loma Linda University ("LLU") in connection with a project that secured initial grant funding from the U.S. Department of Defense. The focus of that project was for skin grafting for burn victims. Twenty years of research at LLU and an affiliated incubator led to a series of discoveries that have been translated into a large patent portfolio of therapeutic approaches that may be applied to the modulation of the immune system in order to induce tolerance to self and transplanted organs.

S-1

We have an exclusive worldwide license for commercializing this nucleic acid-based technology (which is currently at the pre-clinical stage), named Apoptotic DNA Immunotherapy™ (ADi™), which utilizes a novel approach that mimics the way the body naturally induces tolerance to our own tissues ("therapeutically induced immune tolerance"). While immune suppression requires continuous administration to prevent rejection of a transplanted organ, induction of tolerance has the potential to retrain the immune system to accept the organ for longer periods of time. Thus, ADi™ may allow patients to live with transplanted organs with significantly reduced immune suppression. ADi™ is a technology platform which we believe can be engineered to address a wide variety of indications.

We are developing ADi™ products for organ transplantation including skin grafting, autoimmune diseases, and allergies. Our initial focus will be on skin allografts and psoriasis, as we believe these indications will be most efficient in providing safety and efficacy data in clinical trials. To submit a Biologics License Application ("BLA") for a biopharmaceutical product, clinical safety and efficacy must be demonstrated in a series of clinical studies conducted with human subjects. For products in our class of drugs, the first-in-human trials will be a combination of Phase I (safety/tolerability) and Phase II (efficacy) in affected subjects. To obtain approval to initiate the Phase I/IIa studies, an Investigational New Drug Application will be submitted to compile non-clinical efficacy data as well as manufacturing and pre-clinical safety/toxicology data. To date, we have conducted non-clinical studies in a stringent model of skin transplantation using genetically mismatched donor and recipient animals demonstrating a 3-fold increase in the survival of the skin graft in animals that were tolerized with ADi™ compared to animals that receive immune suppression alone. Prolongation of graft life was observed despite discontinuation of immune suppression after the first 5 weeks. Additionally, in an induced non-clinical model for psoriasis, ADi™ treatment resulted in a 69% reduction in skin thickness and a 38% decrease in skin flaking (two clinical parameters for assessment of psoriasis skin lesions). The Phase I/IIa studies in psoriasis will evaluate the safety/tolerability of ADi™ in patients diagnosed with psoriasis. Since the drug will be administered in subjects diagnosed with psoriasis, effectiveness of the drug to improve psoriatic lesions will also be evaluated. In another Phase I/IIa study, patients requiring skin allografts will receive weekly intra-dermal injections of ADi™ in combination with standard immune suppression to assess safety/tolerability and possibility of reducing levels of immunosuppressive drugs as well as prolongation of graft life. Later phase trials are planned after successful completion of these studies in preparation for submission for a BLA to regulatory agencies.

Immune Monitoring

We believe that understanding the status of an individual's immune system is key to developing and administering immunotherapies such as ADi™. We have secured an exclusive worldwide license for commercializing a technology platform which provides a personalized comprehensive profile of the immune system. It is intended to be informative for individual immune responses to viruses, bacterial antigens, peptides, drugs, bone marrow and solid organ transplants, and cancer. It has broad applicability to many other agents of clinical interest impacting the immune system, including those not yet identified such as future infectious agents. We plan to brand this technology, and other future licensed and/or in-house developed monitoring technologies collectively as AditxtScore™.

AditxtScore™ is being designed to allow individuals to understand, manage and monitor their immune profiles in order to be informed about attacks on or by their immune system. We believe AditxtScore™ can also assist the medical community in anticipating possible immune responses and reactions to viruses, bacteria, allergens and transplanted organs. It can be useful in anticipating attacks on the body by having the ability to determine its potential response and for developing a plan to deal with an undesirable reaction by the immune system. Its advantages include the ability to provide a simple, rapid, accurate, high throughput, single platform assay that can be multiplexed to determine the immune status with respect to several factors simultaneously, in 3-16 hours, as well as detect antigen and antibody in a single test (i.e. infectious, recovered, immune). In addition, it can determine and differentiate between various types of cellular and humoral immune responses (T and B cells). It also provides for simultaneous monitoring of cell activation and levels of cytokine release (i.e., cytokine storms).

We plan to utilize AditxtScore™ in our upcoming clinical trials to monitor subjects' immune response before, during and after ADi™ drug administration. We are working with regulatory consultants with the objective to obtain FDA approval for AditxtScore™ as a clinical assay. We are currently securing marketing and distribution partnerships for application of AditxtScore™ in the infectious diseases market. To obtain FDA approval to use AditxtScore™ as a clinical assay, we are performing validation studies to demonstrate AditxtScore™'s utility to evaluate various components of the immune system reproducibly. We believe that these data will show AditxtScore™'s ability to measure various components of the immune system (e.g. humoral and cell-mediated immune responses) to provide a broader view of the immune system and its status in health and disease. Our plan is to submit a 510(K) application to the FDA after compilation of these data. Beyond infectious diseases, we plan to develop AditxtScore™ for applications in additional markets such as organ rejection, allergies, drug/vaccine response, and disease susceptibility.

License Agreement with Leland Stanford Junior University ("Stanford")

On February 3, 2020, we entered into an exclusive license agreement (the "February 2020 License Agreement") with Stanford with regard to a patent concerning a method for detection and measurement of specific cellular responses. Pursuant to the February 2020 License Agreement, we received an exclusive worldwide license to Stanford's patent with regard to use, import, offer, and sale of Licensed Products (as defined in the agreement). The license to the patented technology is exclusive, including the right to sublicense, beginning on the effective date of the agreement and ending when the patent expires. Under the exclusivity agreement, we acknowledged that Stanford had already granted a non-exclusive license in the Nonexclusive Field of Use, under the Licensed Patents in the Licensed Field of Use in the Licensed Territory (as those terms are defined in the February 2020 License Agreement"). However, Stanford agreed to not grant further licenses under the Licensed Patents in the Licensed Field of Use in the Licensed Territory.

We were obligated to pay and paid a fee of $25,000 to Stanford within 60 days of February 3, 2020. We also issued 18,750 shares of the Company's common stock to Stanford. An annual licensing maintenance fee is payable by us on the first anniversary of the February 2020 License Agreement in the amount of $40,000 for 2021 through 2024 and $60,000 starting in 2025 until the license expires upon the expiration of the patent. The Company is required to pay and has paid $25,000 for the issuances of certain patents. The Company will pay milestone fees of $50,000 on the first commercial sales of a licensed product and $25,000 at the beginning of any clinical study for regulatory clearance of an in vitro diagnostic product developed and a potential licensed product. We are also required to: (i) provide a listing of the management team or a schedule for the recruitment of key management positions by March 31, 2020 (which has been completed), (ii) provide a business plan covering projected product development, markets and sales forecasts, manufacturing and operations, and financial forecasts until at least $10,000,000 in revenue by June 30, 2020 (which has been completed), conduct validation studies by September 30, 2020 (which has been completed), (iv) hold a pre-submission meeting with the FDA by September 30, 2020 (which has been completed), (v) submit a 510(k) application to the FDA, Emergency Use Authorization ("EUA"), or a Laboratory Developed Test ("LDT") by March 31, 2021, (vi) obtain FDA approval by December 31, 2021, (vii) complete a prototype assay kit by December 31, 2021, and (viii) have a written agreement with Stanford on further development and commercialization milestones for specific fields of use by December 31, 2021.

Recent Developments

Registered Direct Offering

On August 31, 2021, we sold, in a registered direct offering an aggregate of 4,583,334 shares of common stock at a purchase price of $2.40 per share (the "Shares") for aggregate gross proceeds of approximately $11 million. Concurrently with the sale of the Shares, pursuant to the Purchase Agreement in a concurrent private placement, for each share of common stock purchased by an investor, such investor received from the Company an unregistered warrant (the "Warrant") to purchase one share of common stock. The Warrants have an exercise price of $2.53 per share, and are exercisable for a five year period commencing six months from the date of issuance.

S-4

On August 30, 2021, we entered into a defeasance and waiver agreement (the "Waiver Agreement") with the holder (the "Noteholder") of the senior secured convertible promissory note, issued on January 25, 2021 (the "January 2021 Note"), pursuant to which the Noteholder has agreed in exchange for (a) a cash payment by the Company to the Noteholder of $1.2 million (the "Cash Payment"), (b) a waiver, in part, of the conversion price adjustment provision such that the January 2021 Note shall be convertible into 4,802,497 shares of Common Stock (without giving effect to the conversion notices received by the Company from the Noteholder prior to the date hereof totaling 1,005,748 shares) (the "Conversion Shares") and (c) a voluntary and permanent reduction by the Company of the exercise price of the warrant to purchase 800,000 shares of common stock of the Company (the "January 2021 Warrant") to $2.53 per share, effective as of the Effective Time (as defined below). In addition, the Noteholder agreed that it will forbear from exercising certain rights available to it under the January 2021 Note until October 15, 2021 and that, upon receipt of the Cash Payment (the "Effective Time"), all such rights shall be null and void other than the Company's obligations to deliver the Shares. As of the date of this Prospectus, we have made the Cash Payment and the January 2021 Note has been fully converted by the Noteholder.

The net proceeds from the registered direct offering were approximately $10.1 million, after deducting certain fees due to the placement agent and the Company's estimated transaction expenses, which were used to fund a $6.5M loan to a biopharmaceutical company commercializing COVID-19 antiviral oral therapy, and for general corporate and working capital purposes, including the purchase of fixed assets.

Secured Loan and Credit Agreement

On August 30, 2021, we entered into a secured credit agreement (the "Credit Agreement") with the AiPharma Global Holdings LLC ("AiPharma Global") and certain affiliated entities, pursuant to which we made a secured loan to the AiPharma Global in the principal amount of $6.5 million. The loan bears interest at a rate of 8% per annum and matures on November 30, 2021 or upon such earlier date as the letter of intent or exclusivity period is terminated in accordance with the terms thereof. The loan is secured by certain accounts receivable and other assets of AiPharma Global and certain of its affiliates. The Credit Agreement also contains certain covenants that prohibit AiPharma Global from incurring additional indebtedness, incurring liens or making any dispositions of its property.

Transaction Agreement

On October 4, 2021, we entered into a transaction agreement (the "Transaction Agreement") with the AiPharma Global, pursuant to which we agreed to reach a definitive agreement no later than November 30, 2021 to acquire a subsidiary ("AiPharma Subsidiary" or "Holdco") of AiPharma Global, which is to own all of the assets of AiPharma Global following a restructuring of AiPharma Global, subject to certain termination rights described below.

Pursuant to the Transaction Agreement, the Company also agreed to permit AiPharma Global to borrow an additional principal amount of $8.5 million (the "Additional Borrowings") under the Credit Agreement. We also agreed to amend the Credit Agreement and related documents as promptly as practicable and to extend the maturity date under the Credit Agreement to November 30, 2021.

The Transaction Agreement contemplates two events. First, upon the execution of the definitive agreement (the "Initial Closing"), AiPharma Global would acquire 19.99% of our common stock as of September 30, 2021, subject to the filing of our Quarterly Report on Form 10-Q (the "Initial Shares"), in exchange for 10% of the issued and outstanding equity interests of AiPharma Subsidiary. In addition, we would forgive all amounts then outstanding under the Credit Agreement, as amended. Following the execution of the Definitive Agreement, we also agreed to take all necessary action to cause two individuals designated by AiPharma Global to be appointed to our board of directors. The Secondary Closing (as defined below) is conditioned upon certain closing conditions, including but not limited to: (i) the approvals of the stockholders of the Company of all matters required for the Secondary Closing, and (ii) Nasdaq approval of the issuance of shares to AiPharma Global at the Secondary Closing and the continued listing of the Company's common stock following the Secondary Closing (collectively, the "Closing Conditions").

S-5

The second event under the Transaction Agreement occurs upon the satisfaction of all Closing Conditions (the "Secondary Closing"), the Company shall issue an additional number of shares of the Company's common stock, that yields 65.00% of the Company's outstanding shares of common stock as of September 30, 2021 (the "Secondary Shares") to AiPharma Global in exchange for all remaining equity interests of AiPharma Subsidiary.

The Transaction Agreement may be terminated: (i) by the mutual agreement of the parties, (ii) by either party if the Definitive Agreement has not been executed by November 30, 2021, (iii) by either party if there has been a material breach or any material failure to perform any covenant or agreement and such breach or failure has not been cured or is incapable of being cured, (iv) by us if we are not satisfied with certain due diligence conditions, (v) by our board of directors if it receives a proposal that it deems to be superior to the AiPharma Global proposal described in the Transaction Agreement, (vi) by AiPharma Global if we breach certain covenants under the Transaction Agreement restricting issuances of securities during the period from execution of the Transaction Agreement through the Initial Closing or termination of the Transaction Agreement, or (vii) if at any time prior to the Initial Closing or earlier termination of the Transaction Agreement, the Initial Shares and Secondary Shares (defined below) represent less than 50.1% of our issued and outstanding shares. In the event that the Transaction Agreement is terminated pursuant to (i) or (ii), AiPharma Global is required to pay the Termination Fee to us by November 30, 2021. The Credit Agreement provides for a termination fee of $4 million (the "Termination Fee") in the event that the Definitive Agreement is not entered into by November 30, 2021.In the event that the Transaction Agreement is terminated by us pursuant to (iii) or (iv), AiPharma Global is required to pay the Termination Fee to us by November 30, 2021. In the event that the Transaction Agreement is terminated by AiPharma Global pursuant to (iii) or (vi), we are required to pay AiPharma Global a termination fee of $4 million and AiPharma Global is not required to pay the Termination Fee. In the event that the Transaction Agreement is terminated by AiPharma Global pursuant to (vii), neither party is required to pay the Termination Fee.

Although we are working towards a definitive agreement, we cannot provide any assurance that we will successfully effect the acquisition of AiPharma Global or, if we are able to consummate such a transaction, that the terms of any such acquisition transaction will be favorable to and approved by our stockholders. See "Risk Factors" beginning on page S-8 of this prospectus supplement, including the risk factors incorporated by reference herein, for further discussion surrounding the letter of intent and the transactions contemplated thereby.

RISK FACTORS

An investment in our securities involves a high degree of risk. Before deciding whether to invest in our securities, you should consider carefully the risks described below and discussed under the section captioned "Risk Factors" contained in our Annual Report on Form 10-K for the year ended December 31, 2020 and our Quarterly Reports on Form 10-Q for the quarters ended March 31, 2021 and June 30, 2021, which are incorporated by reference in this prospectus supplement and the accompanying prospectus in their entirety, together with other information in this prospectus supplement, the accompanying prospectus, the information and documents incorporated herein and therein by reference, and in any free writing prospectus that we have authorized for use in connection with this offering. If any of these risks actually occurs, our business, financial condition, results of operations or cash flow could be seriously harmed. This could cause the trading price of our Common Stock to decline, resulting in a loss of all or part of your investment.

Risks Related to this Offering

Management will have broad discretion as to the use of the proceeds from this offering, and we may not use the proceeds effectively.

Our management will have broad discretion in the application of the net proceeds we receive in this offering, including for any of the purposes described in the section entitled "Use of Proceeds," and you will not have the opportunity as part of your investment decision to assess whether our management is using the net proceeds appropriately. Because of the number and variability of factors that will determine our use of our net proceeds from this offering, including the possibility that the proceeds are used to support any products or product candidates acquired in any transaction with AiPharma Global, their ultimate use may vary substantially from their currently intended use. 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 and cause the price of our Common Stock to decline. Pending their use, we may invest our net proceeds from this offering in short-term, investment-grade, interest-bearing securities. These investments may not yield a favorable return to our stockholders.

You will experience immediate and substantial dilution in the net tangible book value per share of the Common Stock you purchase.

Since the price per share of our Common Stock being offered is substantially higher than the net tangible book value per share of our Common Stock, you will suffer immediate and substantial dilution in the net tangible book value of the Common Stock you purchase in this offering. Based on an offering price of $1.50 per share, if you purchase shares of Common Stock in this offering, you will suffer immediate and substantial dilution of $0.62 per share with respect to the net tangible book value of the Common Stock. See the section entitled "Dilution" below for a more detailed discussion of the dilution you will incur if you purchase Common Stock in this offering.

Certain Risks Related to our Common Stock

Future sales or issuances of substantial amounts of our Common Stock, including, potentially, as a result of the acquisition transaction with AiPharma Global, could result in significant dilution.

As disclosed elsewhere in this prospectus supplement, we are contemplating a potential acquisition transaction with AiPharma Global, a biopharmaceutical company that is commercializing a COVID-19 antiviral oral therapy. In the event that the proposed merger transaction with AiPharma Global is completed, we would expect to issue such number of shares of common stock of the Company that yields 50% of the number of our outstanding shares post-closing of the transaction to the stockholders of AiPharma Global. Additionally, we may elect to raise additional capital due to market conditions or strategic considerations as a result of the acquisition transaction. If additional shares are issued in connection with the proposed acquisition transaction or additional capital is raised through the sale of equity or convertible debt securities, the issuance of those securities could result in further dilution to investors purchasing our Common Stock in this offering.

S-8

We have issued a significant number of options, warrants and shares of convertible preferred stock and may continue to do so in the future. The vesting and, if applicable, exercise of these securities and the sale of the shares of Common Stock issuable thereunder may dilute your percentage ownership interest and may also result in downward pressure on the price of our Common Stock.

As of the date of this prospectus supplement, we have issued and outstanding options to purchase 2,143,000 shares of our Common Stock with a weighted average exercise price of $3.18, 465,000 restricted stock awards subject to vesting, 1,575,400 restricted stock units subject to vesting, and warrants to purchase 10,276,217, shares of our Common Stock with a weighted average exercise price of $3.31. Because the market for our Common Stock may be thinly traded, the sales and/or the perception that those sales may occur, could adversely affect the market price of our Common Stock. Furthermore, the mere existence of a significant number of shares of Common Stock issuable upon vesting and, if applicable, exercise of these securities may be perceived by the market as having a potential dilutive effect, which could lead to a decrease in the price of our Common Stock.

While we have entered into a Transaction Agreement with AiPharma Global , we cannot assure you that the transactions contemplated by the Transaction Agreement will be consummated or, that if such transactions are consummated, they will be accretive to stockholder value.

On October 4, 2021, we entered into a Transaction Agreement with AiPharma Global, pursuant to which we agreed to reach a definitive agreement no later than November 30, 2021 to acquire a subsidiary ("AiPharma Subsidiary" or "Holdco") of AiPharma Global, which is to own all of the assets of AiPharma Global following a restructuring of AiPharma Global. Pursuant to the Transaction Agreement, we agreed to permit AiPharma Global to borrow an additional principal amount of $8.5 million under a Secured Credit Agreement entered into between us and AiPharma Global, and certain subsidiaries of AiPharma Global, on August 30, 2021. To the extent that AiPharma Global does not request the full amount of such permitted additional borrowings, we will be required to fund any unused availability under the Credit agreement at the closing of the transactions contemplated by the Transaction Agreement. We may be required to obtain additional financing through the sale of additional equity and/or debt securities to fund such obligations under the Transaction Agreement. Such financing, if available, may not be on favorable terms and may result in additional dilution to our current stockholders.

There is no guarantee that we will agree to terms or definitive agreement with AiPharma Global in order to effect the proposed acquisition transaction. Further, even if we are able to agree to terms with AiPharma Global for an acquisition transaction, there is no guarantee that the terms will be favorable to and approved by our stockholders, that the transaction will be completed in the time frame or in the manner currently anticipated, or that we will recognize the anticipated benefits of the transaction.

We may engage in future acquisitions or strategic transactions, including the transaction with AiPharma Global, which may require us to seek additional financing or financial commitments, increase our expenses and/or present significant distractions to our management.

As described herein, we have recently entered into Transaction Agreement with AiPharma Global which enables us to conduct due diligence and negotiate the terms of a definitive acquisition agreement. We may need to acquire additional financing to fund our obligations under the Transaction Agreement or to fund other potential acquisitions or strategic transactions (particularly, if the acquired entity is not cash flow positive or does not have significant cash on hand). Obtaining financing through the issuance or sale of additional equity and/or debt securities, if possible, may not be at favorable terms and may result in additional dilution to our current stockholders. Additionally, any such transaction may require us to incur non-recurring or other charges, may increase our near and long-term expenditures and may pose significant integration challenges or disrupt our management or business, which could adversely affect our operations and financial results. For example, an acquisition or strategic transaction may entail numerous operational and financial risks, including the risks outlined above and additionally:

exposure to unknown liabilities;
disruption of our business and diversion of our management's time and attention in order to develop acquired products or technologies;
higher than expected acquisition and integration costs;
write-downs of assets or goodwill or impairment charges;
increased amortization expenses;
difficulty and cost in combining the operations and personnel of any acquired businesses with our operations and personnel;
impairment of relationships with key suppliers or customers of any acquired businesses due to changes in management and ownership; and
inability to retain key employees of any acquired businesses.

Accordingly, although there can be no assurance that we will undertake or successfully complete any transactions of the nature described above, and any transactions that we do complete could have a material adverse effect on our business, results of operations, financial condition and prospects.

S-10

USE OF PROCEEDS

We expect that the net proceeds from the sale of the shares of common stock that we are offering will be approximately $3.7 million, after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us. We intend to use the net proceeds from this offering to fund additional borrowings under the Secured Credit Agreement with AiPharma Global, and for general corporate and working capital purposes, including the purchase of fixed assets. We will only receive additional proceeds from the exercise of the Warrants issuable in connection with the private placement if the Warrants are exercised and the holders of such Warrants pay the exercise price in cash upon such exercise and do not utilize the cashless exercise provision of the Warrants.

S-11

DILUTION

Purchasers of common stock in this offering will experience immediate dilution to the extent of the difference between the public offering price per share of common stock and the net tangible book value per share of common stock immediately after this offering and the concurrent private placement.

Our net tangible book value on a pro forma basis as of June 30, 2021 was approximately $15.8 million, or $0.82 per share of common stock, as adjusted for the proceeds received and shares issued pursuant to the offering by us of $11.0 million of our securities that closed on August 30, 2021. Net tangible book value per share is determined by dividing the net of total tangible assets less total liabilities, by the aggregate number of shares of common stock outstanding as of June 30, 2021. After giving effect to: (i) to the offering and sale by us of $11.0 million of our securities that closed on August 30, 2021, and (ii) the sale by us of 2,833,333 shares of common stock at the public offering price of $1.50 per share of common stock and after deducting the estimated underwriting discounts and commissions and estimated offering expenses, our net tangible book value as of June 30, 2021 would have been approximately $19.5 million, or $0.88 per share of common stock. This represents an immediate increase in net tangible book value of $0.06 per share to our existing stockholders and an immediate dilution of $0.62 per share of common stock issued to the investors participating in this offering.

The following table illustrates this per share dilution:

Amount
Public offering price per share $ 1.50
Pro forma Net tangible book value per share at June 30, 2021(1) $ 0.82
Increase in pro forma net tangible book value per share to the existing stockholders attributable to this offering $ 0.06
Pro forma as adjusted net tangible book value per share attributable to this offering $ 0.88
Dilution per share to investors participating in this offering $ 0.62
(1) The figure for the pro forma net tangible book value per share as of June 30, 2020 in the table above takes into account the proceeds received and shares issued pursuant to the offering by us of $11.0 million of our securities that closed on August 30, 2021.

The above table is based on 24,077,013 shares of common stock outstanding as of the date hereof and excludes:

10,276,217 shares of common stock issuable upon the exercise of outstanding warrants as of that date having a weighted average exercise price of $3.31 per share;
2,143,000 shares of our common stock issuable upon the exercise of outstanding option under our 2017 Equity Incentive Plan, or the 2017 Plan; and
1,445,400 shares of our common stock subject to outstanding Restricted Stock Units under our 2021 Omnibus Equity Incentive Plan.

To the extent that any outstanding stock options, restricted stock units, warrants or shares of convertible preferred stock are converted or exercised, new options are issued under our equity incentive plans and subsequently exercised or we issue additional shares of Common Stock in the future, there will be further dilution to new investors participating in this offering.

S-12

UNDERWRITING

Subject to the terms and conditions of the underwriting agreement, the underwriters named below have agreed to purchase from us the number of shares set forth opposite each underwriter's name at a public offering price less the underwriting discounts and commissions set forth on the cover page of this prospectus.

Underwriter Number of Units
Revere Securities LLC 2,833,333
Total 2,833,333

Subject to the terms and conditions set forth in the underwriting agreement, the underwriters have agreed, severally and not jointly, to purchase all of the shares sold under the underwriting agreement if any of these shares are purchased. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the nondefaulting underwriters may be increased or the underwriting agreement may be terminated.

We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the "Securities Act"), or to contribute to payments the underwriters may be required to make in respect of those liabilities.

The underwriters are offering the shares, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the shares, and other conditions contained in the underwriting agreement, such as the receipt by the underwriters of officer's certificates and legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

Discount, Commissions and Expenses

The representative has advised us that the underwriters propose initially to offer the shares to the public at the public offering price set forth on the cover page of this prospectus supplement and to dealers at that price less a concession not in excess of $0.12 per share. After the initial offering, the public offering price, concession or any other term of the offering may be changed.

The following table summarizes the underwriting discount and commissions we will pay to the underwriters in connection with this offering. These amounts are shown assuming both no exercise and full exercise of the underwriters' option to purchase additional shares. The underwriting fee is the difference between the initial price to the public and the amount the underwriters pay to us for the shares.

Per share Total
Public Offering Price $ 1.50 $ 4,249,999.50
Underwriting discounts and commissions $ 0.12 $ 339,999.96
Proceeds, before expenses, to us $ 1.38 $ 3,909,999.54

S-13

In addition to the underwriting discount and commissions to be paid by us, we have agreed to reimburse the underwriters for certain of their out-of-pocket expenses incurred in connection with this offering, including, among other things, the reasonable fees and disbursements of counsel for the underwriters as set forth in the underwriting agreement, in an amount not greater than $75,000.

The expenses of the offering, not including the underwriting discount and commissions, are estimated at $200,000 and are payable by us.

Nasdaq Listing

The shares are listed on the Nasdaq Capital Market under the symbol "ADTX."

Price Stabilization, Short Positions and Penalty Bids

Until the distribution of the shares is completed, SEC rules may limit underwriters and selling group members from bidding for and purchasing our common stock. However, the representative may engage in transactions that stabilize the price of the common stock, such as bids or purchases to peg, fix or maintain that price.

In connection with the offering, the underwriters may purchase and sell our common stock in the open market. These transactions may include short sales, purchases on the open market to cover positions created by short sales and stabilizing transactions. Short sales involve the sale by the underwriters of a greater number of shares than they are required to purchase in the offering. "Covered" short sales are sales made in an amount not greater than the underwriters' option to purchase additional shares described above. The underwriters may close out any covered short position by either exercising their option to purchase additional shares or purchasing shares in the open market. In determining the source of shares to close out the covered short position, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase shares through the option granted to them. "Naked" short sales are sales in excess of such option. The underwriters must close out any naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of our common stock in the open market after pricing that could adversely affect investors who purchase in the offering. Stabilizing transactions consist of various bids for or purchases of shares of common stock made by the underwriters in the open market prior to the completion of the offering.

Similar to other purchase transactions, the underwriters' purchases to cover the syndicate short sales may have the effect of raising or maintaining the market price of our common stock or preventing or retarding a decline in the market price of our common stock. Penalty bids permit the underwriter to reclaim a selling concession from a syndicate member when the common stock originally sold by the syndicate member is purchased in a stabilizing or syndicate covering transaction to cover syndicate short positions. As a result, the price of our common stock may be higher than the price that might otherwise exist in the open market. The underwriters may conduct these transactions on the Nasdaq Capital Market, in the over-the-counter market or otherwise.

Neither we nor any of the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of our common stock. In addition, neither we nor any of the underwriters make any representation that the representative will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

S-14

Nasdaq Passive Market Making

In connection with this offering, underwriters and selling group members may engage in passive market making transactions in the common stock on the Nasdaq Capital Market in accordance with Rule 103 of Regulation M under the Exchange Act during a period before the commencement of offers or sales of common stock and extending through the completion of distribution. A passive market maker must display its bid at a price not in excess of the highest independent bid of that security. However, if all independent bids are lowered below the passive market maker's bid, that bid must then be lowered when specified purchase limits are exceeded. Passive market making may cause the price of our common stock to be higher than the price that otherwise would exist in the open market in the absence of those transactions. The underwriters and dealers are not required to engage in passive market making and may end passive market making activities at any time.

Electronic Distribution

In connection with the offering, certain of the underwriters or securities dealers may distribute prospectuses by electronic means, such as e-mail.

Other Relationships

Some of the underwriters and their affiliates have engaged in, and may in the future engage in, investment banking and other commercial dealings in the ordinary course of business with us or our affiliates. They have received, or may in the future receive, customary fees and commissions for these transactions.

In addition, in the ordinary course of their business activities, the underwriters and their affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

OUR BUSINESS

Overview

We are a biotech innovation company with a mission of prolonging life and enhancing its quality by improving the health of the immune system.

We are developing biotechnologies specifically focused on improving the health of the immune system through immune reprogramming and monitoring. Our immune reprogramming technologies are currently at the pre-clinical stage and are designed to retrain the immune system to induce tolerance with an objective of addressing rejection of transplanted organs, autoimmune diseases, and allergies. Our immune monitoring technologies are designed to provide a personalized comprehensive profile of the immune system and we plan to utilize them in our upcoming reprogramming clinical trials to monitor subjects' immune response before, during and after drug administration.

Our Business

We are a biotech innovation company with a mission of prolonging life and enhancing its quality by improving the health of the immune system. Our immune reprogramming technology is currently at the pre-clinical stage and designed to retrain the immune system to induce tolerance with an objective of addressing rejection of transplanted organs, autoimmune diseases, and allergies. Our immune monitoring technology is designed to provide a personalized comprehensive profile of the immune system and we plan to utilize it in our upcoming clinical trials to monitor subjects' immune response before, during and after drug administration.

Immune Reprogramming

The discovery of immunosuppressive (anti-rejection and monoclonal) drugs over 40 years ago has made possible life-saving organ transplantation procedures and blocking of unwanted immune responses in autoimmune diseases. However, immune suppression leads to significant undesirable side effects, such as increased susceptibility to life-threatening infections and cancers, because it indiscriminately and broadly suppresses immune function throughout the body. While the use of these drugs has been justifiable because they prevent or delay organ rejection, their use for treatment of autoimmune diseases and allergies may not be acceptable because of the above-mentioned side effects. Furthermore, transplanted organs often ultimately fail despite the use of immune suppression, and about 40% of transplanted organs survive no more than 5 years.

New, focused therapeutic approaches are needed to modulate only the small portion of immune cells that are involved in rejection of the transplanted organ, as this approach can be safer for patients than indiscriminate immune suppression. Such approaches are referred to as immune tolerance, and when therapeutically induced, may be safer for patients and also potentially allow long-term survival of transplanted tissues and organs.

In the late 1990s, academic research on these approaches was conducted at the Transplant Center in Loma Linda University ("LLU") in connection with a project that secured initial grant funding from the U.S. Department of Defense. The focus of that project was for skin grafting for burn victims. Twenty years of research at LLU and an affiliated incubator led to a series of discoveries that have been translated into a large patent portfolio of therapeutic approaches that may be applied to the modulation of the immune system in order to induce tolerance to self and transplanted organs.

We have an exclusive worldwide license for commercializing this nucleic acid-based technology (which is currently at the pre-clinical stage), named Apoptotic DNA Immunotherapy™ (ADi™), which utilizes a novel approach that mimics the way the body naturally induces tolerance to our own tissues ("therapeutically induced immune tolerance"). While immune suppression requires continuous administration to prevent rejection of a transplanted organ, induction of tolerance has the potential to retrain the immune system to accept the organ for longer periods of time. Thus, ADi™ may allow patients to live with transplanted organs with significantly reduced immune suppression. ADi™ is a technology platform which we believe can be engineered to address a wide variety of indications.

1

We are developing ADi™ products for organ transplantation including skin grafting, autoimmune diseases, and allergies. Our initial focus will be on skin allografts and psoriasis, as we believe these indications will be most efficient in providing safety and efficacy data in clinical trials. To submit a Biologics License Application ("BLA") for a biopharmaceutical product, clinical safety and efficacy must be demonstrated in a series of clinical studies conducted with human subjects. For products in our class of drugs, the first-in-human trials will be a combination of Phase I (safety/tolerability) and Phase II (efficacy) in affected subjects. To obtain approval to initiate the Phase I/IIa studies, an Investigational New Drug Application will be submitted to compile non-clinical efficacy data as well as manufacturing and pre-clinical safety/toxicology data. To date, we have conducted non-clinical studies in a stringent model of skin transplantation using genetically mismatched donor and recipient animals demonstrating a 3-fold increase in the survival of the skin graft in animals that were tolerized with ADi™ compared to animals that receive immune suppression alone. Prolongation of graft life was observed despite discontinuation of immune suppression after the first 5 weeks. Additionally, in an induced non-clinical model for psoriasis, ADi™ treatment resulted in a 69% reduction in skin thickness and a 38% decrease in skin flaking (two clinical parameters for assessment of psoriasis skin lesions). The Phase I/IIa studies in psoriasis will evaluate the safety/tolerability of ADi™ in patients diagnosed with psoriasis. Since the drug will be administered in subjects diagnosed with psoriasis, effectiveness of the drug to improve psoriatic lesions will also be evaluated. In another Phase I/IIa study, patients requiring skin allografts will receive weekly intra-dermal injections of ADi™ in combination with standard immune suppression to assess safety/tolerability and possibility of reducing levels of immunosuppressive drugs as well as prolongation of graft life. Later phase trials are planned after successful completion of these studies in preparation for submission for a BLA to regulatory agencies.

Immune Monitoring

We believe that understanding the status of an individual's immune system is key to developing and administering immunotherapies such as ADi™. We have secured an exclusive worldwide license for commercializing a technology platform which provides a personalized comprehensive profile of the immune system. It is intended to be informative for individual immune responses to viruses, bacterial antigens, peptides, drugs, bone marrow and solid organ transplants, and cancer. It has broad applicability to many other agents of clinical interest impacting the immune system, including those not yet identified such as future infectious agents. We plan to brand this technology, and other future licensed and/or in-house developed monitoring technologies collectively as AditxtScore™.

AditxtScore™ is being designed to allow individuals to understand, manage and monitor their immune profiles in order to be informed about attacks on or by their immune system. We believe AditxtScore™ can also assist the medical community in anticipating possible immune responses and reactions to viruses, bacteria, allergens and transplanted organs. It can be useful in anticipating attacks on the body by having the ability to determine its potential response and for developing a plan to deal with an undesirable reaction by the immune system. Its advantages include the ability to provide a simple, rapid, accurate, high throughput, single platform assay that can be multiplexed to determine the immune status with respect to several factors simultaneously, in 3-16 hours, as well as detect antigen and antibody in a single test (i.e. infectious, recovered, immune). In addition, it can determine and differentiate between various types of cellular and humoral immune responses (T and B cells). It also provides for simultaneous monitoring of cell activation and levels of cytokine release (i.e., cytokine storms).

We plan to utilize AditxtScore™ in our upcoming clinical trials to monitor subjects' immune response before, during and after ADi™ drug administration. We are working with regulatory consultants with the objective to obtain FDA approval for AditxtScore™ as a clinical assay. We are currently securing marketing and distribution partnerships for application of AditxtScore™ in the infectious diseases market. To obtain FDA approval to use AditxtScore™ as a clinical assay, we are performing validation studies to demonstrate AditxtScore™'s utility to evaluate various components of the immune system reproducibly. We believe that these data will show AditxtScore™'s ability to measure various components of the immune system (e.g. humoral and cell-mediated immune responses) to provide a broader view of the immune system and its status in health and disease. Our plan is to submit a 510(K) application to the FDA after compilation of these data. Beyond infectious diseases, we plan to develop AditxtScore™ for applications in additional markets such as organ rejection, allergies, drug/vaccine response, and disease susceptibility.

In August 2020, we filed for an Emergency Use Authorization (EUA) with the FDA with the ultimate objective of filing a 510(K) application. In the meantime, we are providing AditxtScore™ as a service as a Laboratory Developed Test (LDT) to assess immunity status to COVID-19.

In early 2021, we established our AditxtScore™ Immune Monitoring Center in Richmond, Virginia (the "Center"). The Center operates as a Clinical Laboratory Improvement Amendments (CLIA) certified facility for the processing of our AditxtScore™ for COVID-19 Lab Developed Test (LDT) for our prospective channel partners, including labs and hospitals.

Recent Developments

January 2021 Private Placement of Notes and Warrants

On January 25, 2021 (the "Closing Date"), the Company entered into a Securities Purchase Agreement (the "Purchase Agreement") with an institutional accredited investor (the "Investor") for the offering, sale, and issuance (the "Offering") by the Company of the Note (a $6,000,000 senior secured convertible promissory note). Concurrently with the sale of the Note, pursuant to the Purchase Agreement, the Company also issued the January 2021 Warrants to the Investor to purchase up to 800,000 shares (the "January 2021 Warrant Shares") of the Company's common stock. As a result of the Offering, the Company received aggregate gross proceeds of $5,000,000.

The Note has a twenty-four month term and is convertible at the option of the Investor at any time prior to maturity in shares of Common Stock (the "Conversion Shares") at an initial conversion price of $4.00 per share, subject to adjustment under certain circumstances. The Note amortizes in nineteen (19) equal monthly installments (the "Installment Payments") starting the first day of the sixth month after the Closing Date (each, an "Installment Date"). At the Company's option, Installment Payments may be made in cash or in shares of the Company's common stock. If the Company elects to repay in cash, the amount payable shall be 105% of the applicable Installment Payment. If the Company elects to repay in shares of common stock, the shares shall be priced at the lowest of (i) the Conversion Price then in effect, and (ii) the greater of (x) the Floor Price (as defined in the Note) and (y) the lower of 90% of the lowest volume weighted average price (VWAP) of the common stock for each of the five (5) Trading Days (as such term is defined in the Note) ending and including the Trading Day immediately prior to the applicable Installment Date.

All Installment Payments are subject to the Investor's right to (a) defer some or all of any Installment Payment to a subsequent Installment Date or (b) to convert an additional Installment Payment of the Note at the then-current Installment Price until the next Installment Date. Upon the occurrence of an Event of Default or a Change of Control (as such terms are defined in the Note), the Note is subject to redemption by the Investor. The Company is prohibited from effecting a conversion of the Note to the extent that, as a result of such exercise, the Investor, together with the its affiliates, would beneficially own more than 4.99% of the number of shares of common stock of the Company outstanding immediately after giving effect to the issuance of the such shares, which beneficial ownership limitation may be increased by Investor up to, but not exceeding, 9.99%.

4

The January 2021 Warrants are immediately exercisable for a period of three (3) years at an exercise price of $4.00 per share, subject to adjustment. After a period of one hundred eight (180) days, if a registration statement covering the resale of the shares of common stock underlying the January 2021 Warrants is not effective, the holder may exercise the January 2021 Warrant by means of a cashless exercise. The Company is prohibited from effecting an exercise of the January 2021 Warrants to the extent that, as a result of such exercise, the holder of the January 2021 Warrants together with the holder's affiliates, would beneficially own more than 4.99% of the number of shares of common stock of the Company outstanding immediately after giving effect to the issuance of the such shares, which beneficial ownership limitation may be increased by the holder up to, but not exceeding, 9.99%.

Additionally, until the earlier of the (i) one year anniversary the Closing Date, and (ii) such time as less than $2 million of aggregate Principal Amount (as such term is defined in the Note) of the Note remains outstanding, the Company is prohibited from effecting or entering into an agreement to effect any issuance of securities involving a Variable Rate Transaction (as such term is defined in the Purchase Agreement).

The Securities We May Offer

We may offer shares of our common stock and preferred stock, various series of debt securities and warrants or rights to purchase any of such securities, either individually or in units, from time to time under this prospectus, together with any applicable prospectus supplement and related free writing prospectus, at prices and on terms to be determined by market conditions at the time of offering. If we issue any debt securities at a discount from their original stated principal amount, then, for purposes of calculating the total dollar amount of all securities issued under this prospectus, we will treat the initial offering price of the debt securities as the total original principal amount of the debt securities. 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, including, to the extent applicable:

designation or classification;
aggregate principal amount or aggregate offering price;
maturity, if applicable;
original issue discount, if any;
rates and times of payment of interest or dividends, if any;
redemption, conversion, exchange or sinking fund terms, if any;
conversion or exchange prices or rates, if any, and, if applicable, any provisions for changes to or adjustments in the conversion or exchange prices or rates and in the securities or other property receivable upon conversion or exchange;
ranking;
restrictive covenants, if any;
voting or other rights, if any; and
important United States federal income tax considerations.

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 100,000,000 shares of common stock, par value $0.001 per share. As of July 1, 2021, 14,688,248 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. 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 3,000,000 shares of preferred stock, par value $0.001 per share. There are currently no shares of preferred stock outstanding. Any authorized and undesignated shares of preferred stock may be issued from time to time in one or more additional 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. 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 and forms of the senior and subordinated indentures are included as an exhibit to the registration statement of which this prospectus is a part. The indentures do not limit the amount of securities that may be issued under it and provides 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.

Rights

We may issue rights to our stockholders to purchase shares of our common stock, preferred stock or the other securities described in this prospectus. We may offer rights separately or together with one or more additional rights, debt securities, preferred stock, common stock or warrants, or any combination of those securities in the form of units, as described in the applicable prospectus supplement. Each series of rights will be issued under a separate rights agreement to be entered into between us and a bank or trust company, as rights agent. The rights agent will act solely as our agent in connection with the certificates relating to the rights of the series of certificates and will not assume any obligation or relationship of agency or trust for or with any holders of rights certificates or beneficial owners of rights. The following description sets forth certain general terms and provisions of the rights to which any prospectus supplement may relate. The particular terms of the rights to which any prospectus supplement may relate and the extent, if any, to which the general provisions may apply to the rights so offered will be described in the applicable prospectus supplement.

Specific rights 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, 2020, filed with the SEC on March 25, 2021, and any updates described in our Quarterly Reports on Form 10-Q, all of which are incorporated herein by reference, and 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.

Actual results or events could differ materially from the plans, intentions and expectations disclosed in these forward-looking statements. Our business and our forward-looking statements involve substantial known and unknown risks and uncertainties, including the risks and uncertainties inherent in our statements regarding:

Our plans to research, develop and commercialize our product candidates;
Our ability to comply with the provisions of our license agreements with Loma Linda University and Leland Stanford Junior University;
The results of clinical testing and trial activities of our product candidates;
Our ability to obtain regulatory approval and market acceptance of, and reimbursement for our products;
Our ability to protect our intellectual property and to develop, maintain and enhance a strong brand;
Our ability to compete and succeed in a highly competitive and evolving industry;
Our lack of operating history on which to judge our business prospects and management;
Our ability to raise capital and the availability of future financing;
Our ability to manage our research, development, expansion, growth, and operating expenses;
Our reliance on third parties to conduct our research, preclinical studies and expected clinical trials;

All of our forward-looking statements are as of the date of this prospectus only. In each case, actual results may differ materially from such forward-looking information. We can give no assurance that such expectations or forward-looking statements will prove to be correct. An occurrence of, or any material adverse change in, one or more of the risk factors or risks and uncertainties referred to in this prospectus or included in our other public disclosures or our other periodic reports or other documents or filings filed with or furnished to the U.S. Securities and Exchange Commission (the "SEC") could materially and adversely affect our business, prospects, financial condition, and results of operations. Except as required by law, we do not undertake or plan to update or revise any such forward-looking statements to reflect actual results, changes in plans, assumptions, estimates or projections or other circumstances affecting such forward-looking statements occurring after the date of this prospectus, even if such results, changes, or circumstances make it clear that any forward-looking information will not be realized. Any public statements or disclosures by us following this prospectus that modify or impact any of the forward-looking statements contained in this prospectus will be deemed to modify or supersede such statements in this prospectus.

This prospectus may include market data and certain industry data and forecasts, which we may obtain from internal company surveys, market research, consultant surveys, publicly available information, reports of governmental agencies and industry publications, articles, and surveys. Industry surveys, publications, consultant surveys, and forecasts generally state that the information contained therein has been obtained from sources believed to be reliable, but the accuracy and completeness of such information is not guaranteed. While we believe that such studies and publications are reliable, we have not independently verified market and industry data from third-party sources.

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 research and development and for other general corporate and working capital purposes. We may also use the net proceeds to repay any debts and/or invest in or acquire additional businesses, products, or technologies on an opportunistic basis, although we have no current commitments 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 Amended and Restated Certificate of Incorporation, as amended and restated (the "Certificate of Incorporation") and our bylaws, as amended and restated (the "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.

The Company is authorized to issue 103,000,000 shares of capital stock, par value $0.001 per share, of which 100,000,000 are shares of common stock and 3,000,000 are shares of "blank check" preferred stock.

As of the date of this prospectus, there were 14,688,248 shares of our common stock issued and outstanding and no shares of preferred stock issued and outstanding

Common Stock

Voting

The holders of our common stock are entitled to one vote for each share held on all matters to be voted on by the Company's stockholders. There shall be no cumulative voting.

Dividends

The holders of shares of our common stock are entitled to dividends when and as declared by the Board from funds legally available therefor if, as and when determined by the Board of Directors of the Company in their sole discretion, subject to provisions of law, and any provision of the Company's Amended and Restated Certificate of Incorporation, as amended from time to time. There are no preemptive, conversion or redemption privileges, nor sinking fund provisions with respect to the common stock.

Liquidation

In the event of any voluntary or involuntary liquidation, dissolution or winding up of our affairs, the holders of our common stock will be entitled to share ratably in the net assets legally available for distribution to stockholders after the payment of or provision for all of our debts and other liabilities.

Fully Paid and Non-assessable

All outstanding shares of common stock are duly authorized, validly issued, fully paid and non-assessable.

Preferred Stock

We are authorized to issue up to 3,000,000 shares of preferred stock. This preferred stock may be issued in one or more series, the terms of which may be determined at the time of issuance by our board of directors without further action by stockholders. The terms of any series of preferred stock may include voting rights (including the right to vote as a series on particular matters), preferences as to dividend, liquidation, conversion and redemption rights and sinking fund provisions. No preferred stock is currently outstanding. The issuance of any preferred stock could materially adversely affect the rights of the holders of our common stock, and therefore, reduce the value of our common stock and the Notes. In particular, specific rights granted to future holders of preferred stock could be used to restrict our ability to merge with, or sell our assets to, a third party and thereby preserve control by the present management.

11

Exclusive Forum

Our Amended and Restated Certificate of Incorporation provides that unless the Company consents in writing to the selection of an alternative forum, the State of Delaware is the sole and exclusive forum for: (i) any derivative action or proceeding brought on behalf of the Company, (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of the Company to the Company or the Company's stockholders, (iii) any action asserting a claim against the Company, its directors, officers or employees arising pursuant to any provision of the DGCL or our Amended and Restated Certificate of Incorporation or the Amended and Restated Bylaws, or (iv) any action asserting a claim against the Company, its directors, officers, employees or agents governed by the internal affairs doctrine, except for, as to each of (i) through (iv) above, any claim as to which the Court of Chancery determines that there is an indispensable party not subject to the jurisdiction of the Court of Chancery (and the indispensable party does not consent to the personal jurisdiction of the Court of Chancery within ten days following such determination), which is vested in the exclusive jurisdiction of a court or forum other than the Court of Chancery, or for which the Court of Chancery does not have subject matter jurisdiction.

Additionally, our Amended and Restated Bylaws provide that unless the Company consents in writing to the selection of an alternative forum, the federal district courts of the United States of America will be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act. Any person or entity purchasing or otherwise acquiring any interest in shares of capital stock of the Corporation are deemed to have notice of and consented to this provision. The Supreme Court of Delaware has held that this type of exclusive federal forum provision is enforceable. There may be uncertainty, however, as to whether courts of other jurisdictions would enforce such a provision, if applicable.

Transfer Agent

The transfer agent and registrar for our common stock is VStock Transfer, LLC.

Changes in Authorized Number

The number of authorized shares of common stock may be increased or decreased subject to the Company's legal commitments at any time and from time to time to issue them, by the affirmative vote of the holders of a majority of the stock of the Company entitled to vote.

Delaware Anti-Takeover Statute

We may become subject to Section 203 of the Delaware General Corporation Law, which prohibits persons deemed to be "interested stockholders" from engaging in a "business combination" with a publicly held Delaware corporation for three years following the date these persons become interested stockholders unless the business combination is, or the transaction in which the person became an interested stockholder was, approved in a prescribed manner or another prescribed exception applies. Generally, an "interested stockholder" is a person who, together with affiliates and associates, owns, or within three years prior to the determination of interested stockholder status did own, 15% or more of a corporation's voting stock. Generally, a "business combination" includes a merger, asset or stock sale, or other transaction resulting in a financial benefit to the interested stockholder. The existence of this provision may have an anti-takeover effect with respect to transactions not approved in advance by the Board of Directors. A Delaware corporation may "opt out" of these provisions with an express provision in its original certificate of incorporation or an express provision in its certificate of incorporation or bylaws resulting from a stockholders' amendment approved by at least a majority of the outstanding voting shares. We have not opted out of these provisions. As a result, mergers or other takeover or change in control attempts of us may be discouraged or prevented.

The Amended and Restated Bylaws establish an advance notice procedure for stockholder proposals to be brought before an annual meeting of our stockholders, including proposed nominations of persons for election to our board of directors. At an annual meeting, stockholders may only consider proposals or nominations specified in the notice of meeting or brought before the meeting by or at the direction of our board of directors. Stockholders may also consider a proposal or nomination by a person who was a stockholder at the time of giving notice and at the time of the meeting, who is entitled to vote at the meeting and who has complied with the notice requirements of the Amended and Restated Bylaws in all respects. The Amended and Restated Bylaws do not give our board of directors the power to approve or disapprove stockholder nominations of candidates or proposals regarding other business to be conducted at a special or annual meeting of our stockholders. However, the Amended and Restated Bylaws may have the effect of precluding the conduct of certain business at a meeting if the proper procedures are not followed. These provisions may also discourage or deter a potential acquirer from conducting a solicitation of proxies to elect the acquirer's own slate of directors or otherwise attempting to obtain control of our company.

The Amended and Restated Bylaws provide that a special meeting of our stockholders may be called only by our Chairman or by resolution adopted by a majority of our board of directors. Because our stockholders do not have the right to call a special meeting, a stockholder could not force stockholder consideration of a proposal over the opposition of our board of directors by calling a special meeting of stockholders prior to such time as a majority of our board of directors, the chairperson of our board of directors, the president or the chief executive officer believed the matter should be considered or until the next annual meeting provided that the requestor met the notice requirements. The restriction on the ability of stockholders to call a special meeting means that a proposal to replace our board of directors also could be delayed until the next annual meeting.

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:

any limit on the amount that may be issued;

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;

13

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;

provisions for a sinking fund purchase or other analogous fund, if any, including the date, if any, on which, and the price at which we are obligated, pursuant thereto or otherwise, to redeem, or at the holder's option, to purchase, the series of debt securities and the currency or currency unit in which the debt securities are payable;

whether the debt securities are to be offered at a price such that they will be deemed to be offered at an "original issue discount" as defined in paragraph (a) of Section 1273 of the Internal Revenue Code of 1986, as amended;
the denominations in which we will issue the series of debt securities, if other than denominations of $1,000 and any integral multiple thereof;
the currency of payment of debt securities if other than U.S. dollars and the manner of determining the equivalent amount in U.S. dollars; and
any other specific terms, preferences, rights or limitations of, or restrictions on, the debt securities, including any additional events of default or covenants provided with respect to the debt securities, and any terms that may be required by us or advisable under applicable laws or regulations.

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.

15

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.

16

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.

17

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.

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.

18

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.

19

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;

20

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.

21

DESCRIPTION OF RIGHTS

General

We may issue rights to our stockholders to purchase shares of our common stock, preferred stock or the other securities described in this prospectus. We may offer rights separately or together with one or more additional rights, debt securities, preferred stock, common stock or warrants, or any combination of those securities in the form of units, as described in the applicable prospectus supplement. Each series of rights will be issued under a separate rights agreement to be entered into between us and a bank or trust company, as rights agent. The rights agent will act solely as our agent in connection with the certificates relating to the rights of the series of certificates and will not assume any obligation or relationship of agency or trust for or with any holders of rights certificates or beneficial owners of rights. The following description sets forth certain general terms and provisions of the rights to which any prospectus supplement may relate. The particular terms of the rights to which any prospectus supplement may relate and the extent, if any, to which the general provisions may apply to the rights so offered will be described in the applicable prospectus supplement. To the extent that any particular terms of the rights, rights agreement or rights certificates described in a prospectus supplement differ from any of the terms described below, then the terms described below will be deemed to have been superseded by that prospectus supplement. We encourage you to read the applicable rights agreement and rights certificate for additional information before you decide whether to purchase any of our rights. We will provide in a prospectus supplement the following terms of the rights being issued:

the date of determining the stockholders entitled to the rights distribution;
the aggregate number of shares of common stock, preferred stock or other securities purchasable upon exercise of the rights;
the exercise price;
the aggregate number of rights issued;
whether the rights are transferrable and the date, if any, on and after which the rights may be separately transferred;
the date on which the right to exercise the rights will commence, and the date on which the right to exercise the rights will expire;
the method by which holders of rights will be entitled to exercise;
the conditions to the completion of the offering, if any;
the withdrawal, termination and cancellation rights, if any;
whether there are any backstop or standby purchaser or purchasers and the terms of their commitment, if any;
whether stockholders are entitled to oversubscription rights, if any;
any applicable material U.S. federal income tax considerations; and
any other terms of the rights, including terms, procedures and limitations relating to the distribution, exchange and exercise of the rights, as applicable.

Each right will entitle the holder of rights to purchase for cash the principal amount of shares of common stock, preferred stock or other securities at the exercise price provided in the applicable prospectus supplement. Rights may be exercised at any time up to the close of business on the expiration date for the rights provided in the applicable prospectus supplement.

Holders may exercise rights as described in the applicable prospectus supplement. Upon receipt of payment and the rights certificate properly completed and duly executed at the corporate trust office of the rights agent or any other office indicated in the prospectus supplement, we will, as soon as practicable, forward the shares of common stock, preferred stock or other securities, as applicable, purchasable upon exercise of the rights. If less than all of the rights issued in any rights offering are exercised, we may offer any unsubscribed securities directly to persons other than stockholders, to or through agents, underwriters or dealers or through a combination of such methods, including pursuant to standby arrangements, as described in the applicable prospectus supplement.

Rights Agent

The rights agent for any rights we offer will be set forth in the applicable prospectus supplement.

22

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."

23

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.

24

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;

25

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.

26

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.

27

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 Securities Exchange Act of 1934, as amended (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.

These documents include periodic reports, such as Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, and Current Reports on Form 8-K, as well as proxy statements.
