Our Company

We are an early-stage clinical biopharmaceutical company focused on developing innovative therapies for precision dermatology using engineered proteins and topical live biotherapeutic products. We have built a proprietary platform that includes a microbial library comprised of approximately 1,500 unique bacterial strains that can be screened for unique therapeutic characteristics. The platform is augmented by an artificial intelligence and machine learning technology that analyzes, predicts and helps screen our library of strains for drug-like molecules. The platform also utilizes a licensed genetic engineering technology, which can enable the transformation of previously genetically intractable strains. Our initial focus is on the development of genetically engineered strains of Staphylococcus epidermidis, or S. epidermidis, which we consider to be an optimal therapeutic candidate species for engineering of dermatologic therapies. The particular species demonstrates a number of well-described properties in the skin. As of the date of this prospectus, we have identified among our microbial library over 60 distinct bacterial species that we believe are capable of being engineered to create living organisms or engineered proteins with significant therapeutic effect.

We are a pioneer in genetically engineered bacteria for therapeutic use in dermatology. Our goal is to leverage our platforms and internal microbial library bacterial strains to create new therapeutics that are either engineered living organisms or engineered proteins or peptides to treat skin diseases. Our initial focus is on the development of our current programs, including:

	●	ATR-12, which includes a genetically modified strain of S. epidermidis for treating the orphan disease, Netherton syndrome, a chronic and sometimes fatal disease of the skin estimated to affect approximately one in every 100,000, but its prevalence may be underestimated due to misdiagnosis caused by similarities to other skin diseases. We received Pediatric Rare Disease Designation for ATR-12 by the United States Food and Drug Administration, or FDA, in 2020. In December 2022, we submitted an investigational new drug application, or IND, for a Phase 1b clinical trial in adult Netherton syndrome patients, and on January 27, 2023 we received notification from the FDA that the “study may proceed” with respect to the proposed Phase 1b clinical trial. After submitting post-IND manufacturing reports, we have commenced operating activities for our Phase 1b clinical trial in December 2023, and we dosed our first patient in August 2024. We expect to report initial safety results in the first half of 2025.

	●	ATR-04, which includes a genetically modified strain of S. epidermidis for treating the papulopustular rash experienced by cancer patients undergoing epidermal growth factor receptor inhibitor, or EGFRi, targeted therapy. In August 2024, we obtained IND clearance from the FDA to commence a Phase 1/2 clinical trial in certain cancer patients undergoing EGFRi targeted therapy. In September 2024, we obtained Fast Track designation by the FDA in this indication. We expect to dose the first patient in the Phase 1/2 clinical trial in the first half of 2025.

	●	ATR-01, which includes a genetically modified strain of S. epidermidis that expresses an engineered recombinant human filaggrin protein for treating ichthyosis vulgaris, a chronic, xerotic (abnormally dry), scaly skin disease with an estimated incidence and prevalence of 1 in 250, which suggests a total patient population of 1.3 million in the United States. We are planning to perform lead optimization and IND-enabling studies in 2025 to support an IND filing.

●

Two separate strains of bacterial microbes have been investigated and developed by us and Bayer Consumer Care AG, the consumer products division of Bayer AG, or Bayer, the international life science company. We entered into a Joint Development Agreement, or JDA, with Bayer in December 2019. Under the terms of the JDA, we are responsible for testing our library of bacterial strains and their natural products for key preclinical properties. After screening through hundreds of strains, we and Bayer have selected two particular strains to move forward into further development. Bayer holds the exclusive option to license the patent rights to these strains.

We also have established partnerships with teams from Carnegie Mellon University and the Fred Hutchinson Cancer Center, or Fred Hutch, two of the premier academic centers in the United States. Our collaboration with the Carnegie Mellon based team also takes advantage of the power of whole genome sequencing. This partnership is mining our proprietary library of bacterial strains for novel, drug like peptides and proteins. The artificial intelligence/machine learning technology developed by this team predicts the molecules made by microbes from their genetic sequences. The system then compares the predictions to the products actually made through tandem mass spectroscopy and/or nuclear magnetic resonance imaging to refine future predictions. The predictions can be compared to publicly available 2D and 3D protein databases to select drug like structures.

We hold an exclusive, worldwide license from Fred Hutch regarding the use of its patented SyngenicDNA Minicircle Plasmid, or SyMPL, technologies for all fields of genetic engineering, including to discover, develop and commercialize engineered microbial therapies and microbial-derived peptides and proteins for skin diseases. We are utilizing our licensed patent rights to build plasmids in order to make genetic transformations that have never been previously achieved. To date, our team has successfully engineered our lead therapeutic candidates without the SyMPL technology. However, we believe that SyMPL will open up the ability to make genetic transformations of an expanded universe of microbial species, and we expect that some or all of our future product candidates will incorporate the SyMPL technology.

Our Strategy

Beyond our three lead product candidates and collaboration with Bayer, our goal is to develop a broad portfolio of product candidates focused on expanding the application of our platforms for precision dermatology. We believe that we have established a unique position in advancing the development of biologics for precision dermatology.

We intend to create a broad portfolio of product candidates for precision dermatology through our development of genetically engineered proteins selected from our proprietary microbial library of approximately 1,500 unique bacterial strains. Our strategy is as follows:

●

Build a sustainable precision dermatology company. Our goal is to build a leading precision dermatology company with a sustainable pipeline of product candidates. To that end, we are focused on rapidly advancing our current pipeline of live biotherapeutic candidates while actively developing additional product candidates. Each of our current product candidates are proprietary and subject to pending patent applications. We expect that most of our genetically engineered product candidates we develop will be eligible for patent protection.

	●	*Advance our lead programs, ATR-12 and ATR-04, through clinical trials*. In 2022, we obtained pre-IND correspondence with the FDA for purposes of discussing our proposed regulatory pathway for the ATR-12 program and obtaining guidance from the FDA on the preclinical plan leading to the filing and acceptance of an IND for ATR-12. In December 2022, we filed an IND for an ATR-12 first-in-human trial in Netherton syndrome patients. On January 27, 2023, we received notification from the FDA that the “study may proceed” with respect to the proposed Phase 1b clinical trial, and in August 2024 we initiated dosing the first patient in the ATR-12 Phase 1b clinical trial. In August 2024, we received IND clearance from the FDA for a first-in-human Phase 1b/2a clinical trial in patients with EGFRi-associated rash, and in September 2024, the FDA granted Fast Track designation for the ATR-04 program. We commenced a Phase 1b trial for our ATR-04 program in certain cancer patients undergoing EGFRi therapy in the fourth quarter of 2024. We expect to dose the first patient in the ATR-04 Phase 1/2 clinical trial in the first half of 2025. We expect to report initial safety results of the first patients dosed in our ATR-12 Phase 1b clinical trial in Netherton syndrome patients in early 2025 with full results anticipated in the second half of 2025.
	●	*Broaden our platform by selectively exploring strategic partnerships that maximize the potential of our precision dermatology programs*. We intend to maintain significant rights to all of our core technologies and product candidates. However, we will continue to evaluate partnering opportunities in which a strategic partner could help us to accelerate development of our technologies and product candidates, provide access to synergistic combinations, or provide expertise that could allow us to expand into the treatment of different types of skin diseases. We may also broaden the reach of our platform by selectively in-licensing technologies or product candidates. In addition, we will consider potentially out-licensing certain of our proprietary technologies for indications and industries that we are not pursuing. We believe our genetic engineering techniques and technologies have applicability outside of the field of medicine, including cosmetics and in the generation of clean fuels and bioremediation.
	●	*Leverage our academic partnerships*. We currently have partnerships with investigators at the Fred Hutchinson Cancer Center, Yale University, Duke University, and Carnegie Mellon University. We expect to leverage these partnerships and potentially expand them or form other academic partnerships to bolster our engineering platforms and expand our research and development pipeline.
	●	*Expand on our other potential product candidates*. Beyond our three lead product candidates, our goal is to develop a broad portfolio of product candidates focused on expanding the application of our platforms for precision dermatology. We have a proprietary platform for discovering and developing therapeutic products for precision dermatology. Our platform is built around a microbial library comprised of approximately 1,500 unique bacterial strains to allow screening for unique therapeutic characteristics and utilizes a microbial genetic technology that analyzes, predicts and engineers the proteins, peptides and molecules made by skin microbes. Our ability to genetically engineer intractable microbial species is uniquely leveraged by our exclusive license to the SyMPL technology.

Our Intellectual Property

As of the date of this prospectus, we own three issued U.S. patents, twelve pending U.S. patent applications, three pending PCT applications and 57 other foreign patents and patent applications that are important to the development of our business.

Our Leadership Team

We are led by Francisco D. Salva, our chief executive officer, and Travis Whitfill Ph.D. MPH, our co-founder and chief operating officer, who have more than 35 years of combined experience in the management of biotechnology companies and healthcare investing. Mr. Salva was previously a co-founder of Acerta Pharma, which was sold to AstraZeneca for approximately $6.3 billion in a staged acquisition in 2016. He also worked on the turnaround of Pharmacyclics, which subsequently sold to Abbvie for approximately $21 billion in 2015. Before that, Mr. Salva spent almost a decade in life sciences venture capital. Dr. Whitfill served as associate research scientist and serves as assistant professor adjunct at Yale University with appointments in the Departments of Pediatrics and Emergency Medicine. He spent nearly a decade in venture capital as a partner in a biotech-focused venture capital fund, Bios Partners. He has led numerous grant-funded projects, holds nearly a dozen patents and has co-authored over 60 publications. Our board of directors (the “Board”) is comprised of renowned group of senior executives, scientists and investors in the biotechnology industry.

Our Competitive Strengths

We are a pioneer in genetically engineering bacteria for therapeutic use in dermatology clinical trials. We have built a proprietary platform that includes a microbial library comprised of approximately 1,500 unique bacterial strains that are screened for therapeutic characteristics as well as lead drug candidates. Furthermore, we have exclusively licensed a novel technology, which potentially enables the genetic transformation of previously intractable bacterial microbes. The history of recombinant protein engineering in biotech has traditionally been limited to less than 20 species. Our licensed technology opens up the potential to genetically engineer thousands of microbial species to build proteins and peptides that have never been previously built. Our management team has significant experience in discovering, developing, manufacturing and commercializing therapeutics. The members of our leadership team have specialized expertise developed at companies including Pharmacyclics, Acerta Pharma, Castle Creek Biosciences, VYNE Therapeutics (fka Menlo Therapeutics), Revance Therapeutics, Biogen, Novartis and Connetics Corp.

Our Market Opportunity

We believe there are significant market opportunities to capture in each of our addressable markets. The dermatology market itself has shown considerable growth over the last decade and is predicted to continue to grow. According to Vision Research Reports, the dermatology drug market surpassed $17 billion in 2021 and is expected to grow at a compound annual growth rate of 8.8% through 2030. Our first product candidate to emerge from our platform focuses on the orphan indication of Netherton syndrome. Based on the Barbati and Sun Studies, we believe that this product candidate represents a potential $250 million global sales opportunity by mid-2030. Our second product candidate focuses on papulopustular rash due to EGFR inhibitors. We believe this product candidate represents a potential $1 billion global sales opportunity by 2030. The diseases we intend to target are well characterized, often by a monogenic genetic mutation. Additionally, the era of genomic sequencing has ushered in unprecedented progress in genetic testing. The defined molecular pathophysiology of over 100 rare skin diseases has now been defined.

Implications of Being an Emerging Growth Company

The Jumpstart Our Business Startups Act, or the JOBS Act, was enacted in April 2012 with the intention of encouraging capital formation in the United States and reducing the regulatory burden on newly public companies that qualify as “emerging growth companies.” We are an emerging growth company within the meaning of the JOBS Act. As an emerging growth company, we may take advantage of certain exemptions from various public reporting requirements, including:

	●	the requirement that our internal control over financial reporting be attested to by our independent registered public accounting firm pursuant to Section 404 of the Sarbanes-Oxley Act of 2002;
	●	certain requirements related to the disclosure of executive compensation in this prospectus and in our periodic reports and proxy statements;
	●	the requirement that we hold a nonbinding advisory vote on executive compensation and any golden parachute payments; and
	●	the ability to delay compliance with new or revised financial accounting standards until private companies are required to comply with the new or revised financial accounting standard.

We may take advantage of the exemptions under the JOBS Act discussed above until we are no longer an emerging growth company. We will remain an emerging growth company until the earliest to occur of (1) the last day of the fiscal year in which we have $1.235 billion or more in annual revenue; (2) the date we qualify as a “large accelerated filer,” with at least $700 million of equity securities held by non-affiliates; (3) the date on which we have issued, in any three-year period, more than $1.0 billion in non-convertible debt securities; or (4) the last day of the fiscal year ending after the fifth anniversary of the IPO.

We may choose to take advantage of some, but not all, of the available benefits under the JOBS Act. We have chosen to take advantage of all of the other exemptions discussed above. Accordingly, the information contained herein and in our subsequent filing with the SEC may be different than the information you receive from other public companies in which you hold stock.

Implications of Being a Smaller Reporting Company

Additionally, we are a “smaller reporting company” as defined in Rule 10(f)(1) of Regulation S-K. Smaller reporting companies may take advantage of certain reduced disclosure obligations, including, among other things, providing only two years of audited financial statements. We will remain a smaller reporting company until the last day of the fiscal year in which (1) the market value of our Common Stock held by non-affiliates equals or exceeds $250 million as of the end of that year’s second fiscal quarter, or (2) our annual revenues equaled or exceeded $100 million during such completed fiscal year and the market value of our Common Stock held by non-affiliates equals or exceeds $700 million as of the end of that year’s second fiscal quarter.

Alumni Transaction

On April 24, 2025, we entered into the Purchase Agreement with Alumni Capital, whereby the Company has the right, but not the obligation, to sell to the Purchaser, and the Purchaser is obligated to purchase, up to an aggregate of $20 million (the “Investment Amount”) of Shares in a series of purchases.

The term of the Purchase Agreement is through December 31, 2026, or the date on which the Purchaser shall have purchased Shares issuable pursuant to the Purchase Agreement for an aggregate purchase price of the Investment Amount. During the term, the Company may at its election cause the Purchaser to make a series of purchases of Shares, each up to $750,000, or up to $4 million dollars upon consent of the Purchaser. The closing of each purchase pursuant to the Purchase Agreement will be no later than five business days after the Company provides a notice to for the purchase. The Company expects to consider market conditions, the trading price of the Common Stock and the availability of other sources of financing when determining whether to make sales under the Purchase Agreement.

The issuance of the Shares to the Purchaser is being made pursuant to exemptions from the registration requirement of the Securities Act provided by Section 4(a)(2) of the Securities Act. Pursuant to the Purchase Agreement, the Company was obligated to file with the Securities and Exchange Commission (the “SEC”), within 60 days of the Purchase Agreement, a registration statement covering the offering and sale of the Shares issued and issuable pursuant to the Purchase Agreement and the Warrant Shares issuable upon exercise of the Warrants. The filing of the registration statement of which this prospectus forms a part was made to satisfy this obligation.

The purchase price of the Shares that the Company elects to sell to the Purchaser pursuant to the Purchase Agreement will be equal to the lowest daily volume weighted average price of the Common Stock during the period commencing on the date that the Company delivers a notice requiring the purchase of Shares by the Purchaser and ending on the earlier to occur of (i) five business days immediately following such date and (ii) the date on which the Purchaser notifies the Company that it is prepared to proceed with the relevant closing, multiplied by 90%.

Upon each purchase, the Purchaser will receive Warrants to purchase such number of shares of the Company’s Common Stock equal to 10% of the number of Shares purchased in the related closing. The exercise price of the Warrants will equal 130% of the price per share paid upon closing. The exercise of the Warrants will be subject to stockholder approval and expire five years after issuance. The Warrants may be exercised via cashless exercise if there is no effective registration statement, or current prospectus available for, the resale of the Warrant Shares.

In no event may the Company issue to the Purchaser under the Purchase Agreement shares of Common Stock in an amount greater than 19.99% of the total number of shares of Common Stock issued and outstanding immediately prior to the execution of the Purchase Agreement (the “Exchange Cap”), unless the Company obtains stockholder approval to issue shares of Common Stock in excess of the Exchange Cap. In any event, the Purchase Agreement provides that the Company may not issue or sell any Shares under the Purchase Agreement if such issuance or sale would breach any applicable NYSE American LLC rules.

The Purchase Agreement prohibits the Company from directing the Purchaser to purchase any shares of Common Stock if those Shares, when aggregated with all other shares of Common Stock then beneficially owned by the Purchaser (as calculated pursuant to Section 13(d) of the Securities Exchange Act of 1934, as amended), would result in the Purchaser beneficially owning more than 4.99% of the outstanding Common Stock.

RISK FACTORS

Any investment in our securities involves a high degree of risk. You should carefully consider the risks described below and set forth in the section “Risk Factors” in our 2024 Form 10-K, as well as any amendment or update to our risk factors reflected in subsequent filings with the SEC, which are incorporated by reference in this prospectus, and all other information contained in this prospectus and incorporated by reference in this prospectus, before you make a decision to invest in our securities. Please note that the risks highlighted here are not the only ones that we may face. For example, additional risks presently unknown to us or that we currently consider immaterial or unlikely to occur could also impair our operations. If any of the following events occur or any additional risks presently unknown to us actually occur, our business, financial condition and operating results may be materially adversely affected. In that event, the trading price of our Common Stock could decline and you could lose all or part of your investment.

Risks Relating to this Offering

Risks Related to this Offering

As an investor, you may lose all of your investment.

Investing in our securities involves a high degree of risk. As an investor, you may never recoup all, or even part, of your investment and you may never realize any return on your investment. You must be prepared to lose all of your investment.

We will need additional financing to execute our business plan and fund operations, which additional financing may not be available on reasonable terms or at all.

As of December 31, 2024, we had total assets of $7,358,802 and working capital of $3,852,433. We believe that net proceeds of this offering, along with our cash on hand as of the date of this prospectus, will not be sufficient to cover our proposed plan of operations over, at least, the next 12 months. We intend to seek additional funds through various financing sources, including the sale of our equity, licensing fees for our technology and joint ventures with industry partners. In addition, we will consider alternatives to our current business plan that may enable to us to achieve revenue producing operations and meaningful commercial success with a smaller amount of capital. However, there can be no guarantees that such funds will be available on commercially reasonable terms, if at all. If such financing is not available on satisfactory terms, we may be unable to further pursue our business plan and we may be unable to continue operations, in which case you may lose your entire investment.

The report of our independent registered public accounting firm for the year ended December 31, 2024 states that due to our accumulated deficit, recurring and negative cash flow from operations there is substantial doubt about our ability to continue as a going concern.

It is not possible to predict the actual number of Shares we will sell under the Purchase Agreement to the Selling Stockholder, or the actual gross proceeds resulting from those sales.

Subject to certain limitations in the Purchase Agreement and compliance with applicable law, we have the discretion to deliver notices to the Selling Stockholder at any time throughout the term of the Purchase Agreement. The actual number of Shares that are sold to the Selling Stockholder may depend based on a number of factors, including the market price of the Common Stock during the sales period. Actual gross proceeds may be less than $20 million, which may impact our future liquidity. Because the price per share of each Share sold to the Selling Stockholder will fluctuate during the sales period, it is not currently possible to predict the number of Shares that will be sold or the actual gross proceeds to be raised in connection with those sales.

The terms of the Purchase Agreement limit the amount of Shares we may issue to the Selling Stockholder, which may limit our ability to utilize the arrangement to enhance our cash resources.

The Purchase Agreement includes restrictions on our ability to sell our Shares to Alumni, including, subject to specified limitations, if a sale would cause Alumni to beneficially own more than 4.99% of our issued and outstanding shares of Common Stock we may not sell to Alumni any Shares. Accordingly, we cannot guarantee that we will be able to sell the full amount of Shares that Alumni has committed to purchase, if any. If we cannot sell the full amount of Shares that Alumni has committed to purchase because of these limitations, we may be required to utilize more costly and time-consuming means of accessing the capital markets, which could materially adversely affect our liquidity and cash position.

The market price of our Common Stock may be subject to fluctuation and volatility. You could lose all or part of your investment.

The market price of our Common Stock is subject to wide fluctuations in response to various factors, some of which are beyond our control. Since shares of our Common Stock were sold in our initial public offering (“IPO”) in June 2023 at a price of $150.00 per share, the reported high and low sales prices of our Common Stock have ranged from $155.40 to $0.25 through April 25, 2025. The market price of our Common Stock on the NYSE American may fluctuate as a result of a number of factors, some of which are beyond our control, including, but not limited to:

	●	actual or anticipated variations in our and our competitors’ results of operations and financial condition;
	●	changes in earnings estimates or recommendations by securities analysts, if our shares are covered by analysts;
	●	market acceptance of our product candidates;
	●	development of technological innovations or new competitive products by others;
	●	announcements of technological innovations or new products by us;
	●	publication of the results of preclinical or clinical trials for our product candidates;
	●	failure by us to achieve a publicly announced milestone;
	●	delays between our expenditures to develop and market new or enhanced products and the generation of sales from those products;
	●	developments concerning intellectual property rights, including our involvement in litigation brought by or against us;
	●	regulatory developments and the decisions of regulatory authorities as to the approval or rejection of new or modified products;
	●	changes in the amounts that we spend to develop, acquire or license new products, technologies or businesses;
	●	changes in our expenditures to promote our product candidates;
	●	our sale or proposed sale, or the sale by our significant stockholders, of our shares or other securities in the future;
	●	changes in key personnel;
	●	success or failure of our research and development projects or those of our competitors;
	●	the trading volume of our shares; and
	●	general economic and market conditions and other factors, including factors unrelated to our operating performance.

These factors and any corresponding price fluctuations may materially and adversely affect the market price of our shares and result in substantial losses being incurred by our investors. In the past, following periods of market volatility, public company stockholders have often instituted securities class action litigation. If we were involved in securities litigation, it could impose a substantial cost upon us and divert the resources and attention of our management from our business.

Our charter limits our ability to issue shares.

Our charter authorizes us to issue up to 100,000,000 shares of Common Stock, with 14,979,354 shares of Common Stock, 41,608 options, and 13,628,614 warrants outstanding, as well as 7,457 shares reserved for issue under our 2016 equity plan and 1,209,735 shares reserved under our 2023 equity incentive plan, 71,350,424 shares of Common Stock remain issuable as of the date of this prospectus, prior to the issuance of any shares under the terms of the Purchase Agreement. Additional shares may become issuable with the expiration of currently outstanding warrants or if we effect a reverse share split in the future. We may register additional shares as they become issuable. Nonetheless, depending on our share price, we may not be able to issue sufficient shares to realize the full $20.0 million in proceeds from the Purchase Agreement.

Investors who buy shares at different times will likely pay different prices.

Investors who purchase Shares in this offering at different times will likely pay different prices, and so may experience different levels of dilution and different outcomes in their investment results. Pursuant to the terms of the Purchase Agreement, we will have discretion, subject to market demand, to vary the timing, prices, and numbers of Shares sold to Alumni Capital. Similarly, Alumni Capital may sell such Shares at different times and at different prices. Investors may experience a decline in the value of the Shares they purchase from the Selling Stockholder in this offering as a result of sales made by us in future transactions to Alumni Capital at prices lower than the prices they paid.

The issuance of Common Stock to the Selling Stockholder may cause substantial dilution to our existing stockholders, and the sale of such shares acquired by the Selling Stockholder could cause the price of our Common Stock to decline.

We are registering for resale by the Selling Stockholder up to 73,578,595 shares of Common Stock, consisting 73,000,000 Shares that we may issue and sell to the Selling Stockholder under the Purchase Agreement from time to time and up to 7,300,000 Warrant Shares issuable upon exercise of the Warrants. The number of shares of our Common Stock ultimately offered for resale by the Selling Stockholder under this prospectus is dependent upon the number of shares of Common Stock issued to the Selling Stockholder pursuant to the Purchase Agreement. Depending on a variety of factors, including market liquidity of our Common Stock, the issuance of Shares to the Selling Stockholder may cause the trading price of our Common Stock to decline.

The Selling Stockholder is irrevocably bound to purchase up to 7,300,000 Shares being registered for resale hereby provided that the conditions set forth in the Purchase Agreement are met within the limitation set forth in the Purchase Agreement and, following receipt by the Selling Stockholder of Shares issued to the Selling Stockholder under the Purchase Agreement, the Selling Stockholder may sell all, some or none of such Shares. The sale of a substantial number of shares of our Common Stock by the Selling Stockholder in this offering, or anticipation of such sales, could cause the trading price of our Common Stock to decline or make it more difficult for us to sell equity or equity-related securities in the future at a time and at a price that we might otherwise desire.

Our failure to meet the continued listing requirements of the NYSE American could result in a delisting of our Common Stock.

If we fail to satisfy the continued listing requirements of the NYSE American, such as the corporate governance requirements or the minimum closing bid price requirement, the NYSE American may take steps to delist our Common Stock. Such a delisting would likely have a negative effect on the price of our Common Stock and would impair your ability to sell or purchase our Common Stock when you wish to do so. In the event of a delisting, we can provide no assurance that any action taken by us to restore compliance with listing requirements would allow our Common Stock to become listed again, stabilize the market price or improve the liquidity of our Common Stock, prevent our Common Stock from dropping below the NYSE American’s minimum bid price requirement or prevent future non-compliance with the NYSE American’s listing requirements.

Future capital raises may dilute your ownership and/or have other adverse effects on our operations.

If we raise additional capital by issuing equity securities, our existing stockholders’ percentage ownership will be reduced and these stockholders may experience substantial dilution. If we raise additional funds by issuing debt securities, these debt securities would have rights senior to those of our Common Stock and the terms of the debt securities issued could impose significant restrictions on our operations, including liens on our assets. If we raise additional funds through collaborations and licensing arrangements, we may be required to relinquish some rights to our intellectual property or candidate products, or to grant licenses on terms that are not favorable to us.

We have not paid dividends on our Common Stock in the past and have no immediate plans to pay such dividends.

We plan to reinvest all of our earnings, to the extent we have earnings, to cover operating costs and otherwise become and remain competitive. We do not plan to pay any cash dividends with respect to our Common Stock in the foreseeable future. We cannot assure you that we would, at any time, generate sufficient surplus cash that would be available for distribution to the holders of our Common Stock as a dividend. Therefore, you should not expect to receive cash dividends on the Common Stock we are offering.

Our management will have broad discretion over the use of the net proceeds from our sale of shares of Common Stock to Alumni Capital, you may not agree with how we use the proceeds and the proceeds may not be invested successfully.

Our management will have broad discretion over the use of proceeds from this offering. We intend to use the net proceeds from this offering, primarily for strategic opportunities, working capital and other general corporate purposes. Our management will have considerable discretion in the application of the net proceeds, and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used appropriately. The net proceeds, if any, may be used for corporate purposes that do not improve our operating results or enhance the value of our Common Stock. The failure of our management to use these funds effectively could have a material adverse effect on our business, cause the market price of our Common Stock to decline and impair the commercialization of our products and/or delay the development of our product candidates. Pending their use, we may invest the net proceeds from this offering in short-term, investment-grade, interest-bearing instruments and U.S. government securities. These investments may not yield a favorable return to our stockholders.

The Alumni Capital Transaction

General

On April 24, 2025, we entered into a Purchase Agreement (the “Purchase Agreement”) with Alumni Capital LP (“Alumni Capital”). Pursuant to the Purchase Agreement, we have the right to sell to Alumni Capital up to an aggregate of $20 million (the “Investment Amount”) of the shares of our Common Stock from time to time during the term of the Purchase Agreement, subject to certain conditions and limitations. Sales of Shares pursuant to the Purchase Agreement, and the timing of any sales, are solely at our option and we are under no obligation to sell securities pursuant to this arrangement. Shares may be sold by us pursuant to this arrangement over a period ending on the earlier of December 31, 2026, or the date on which Alumni Capital shall have purchased Shares pursuant to the Purchase Agreement for an aggregate purchase price of the Investment Amount; provided, however that we can terminate the Purchase Agreement at any time upon three days’ written notice, subject to the satisfaction of the conditions in the Purchase Agreement.

Upon the satisfaction of the conditions in the Purchase Agreement, including that a registration statement that we agreed to file with the SEC pursuant to the Purchase Agreement is declared effective by the SEC and a final prospectus in connection therewith is filed with the SEC, we will have the right, but not the obligation, from time to time at our sole discretion over the period described above, to direct Alumni Capital to purchase up to a fixed maximum number of Shares as set forth in the Purchase Agreement; provided, that Alumni Capital’s maximum commitment under any single fixed purchase will not exceed $750,000. Such limitation may be waived by mutual agreement between us and Alumni Capital, and, in such case, the maximum commitment amount shall be $4 million.

The purchase price per Share that may be sold to Alumni Capital under the Purchase Agreement in such fixed purchases equals 90% of the lowest daily dollar volume-weighted average price for the Common Stock during the period commencing on the date that the Company delivers to Alumni Capital a purchase notice and ending on the earlier to occur of (i) five business days immediately following such date and (ii) the date on which the Alumni Capital notifies the Company that it is prepared to proceed with the purchase. There is no upper limit on the price per share that Alumni Capital might be obligated to pay for the Common Stock under the Purchase Agreement.

Upon each purchase, the Purchaser will receive Warrants to purchase such number of shares of Common Stock equal to 10% of the number of Shares purchased in the related single fixed purchase. The exercise price of the Warrant shall equal 130% of the price per Share paid upon closing of the related purchase. The Warrant is exercisable upon stockholder approval and expires five years after issuance. The Warrants may be exercised via cashless exercise if there is no effective registration statement, or current prospectus available for, the resale of the Warrant Shares. The issuance of the Shares and the Warrants to Alumni Capital is being made pursuant to exemptions from the registration requirement of the Securities Act provided by Section 4(a)(2) thereof.

The Company will control the timing and amount of any sales of Shares to Alumni Capital. Actual sales of Shares to Alumni Capital under the Purchase Agreement will depend on a variety of factors to be determined by us from time to time, including, among other things, market conditions, the trading price of the Common Stock and determinations by us as to the appropriate sources of funding for us and our operations.

Under the applicable rules of the NYSE American, in no event may we issue more than 2,994,372 Shares (including the Warrant Shares), representing 19.99% of the shares of the Common Stock outstanding immediately prior to the execution of the Purchase Agreement (the “Exchange Cap”) to Alumni Capital under the Purchase Agreement, unless we obtain stockholder approval to issue shares of Common Stock in excess of the Exchange Cap. Notwithstanding such limitation, the Exchange Cap does not apply to the extent the purchase price is equal to or exceeds the Minimum Price (as defined in the Purchase Agreement).

In all instances, we may not sell securities to Alumni Capital under the Purchase Agreement if such sale would result in Alumni Capital beneficially owning more than 4.99% of the Common Stock (the “Beneficial Ownership Limitation”). Alumni Capital may increase the Beneficial Ownership Limitation upon 61 days’ written notice, subject to our approval.

The net proceeds from sales, if any, under the Purchase Agreement, will depend on the frequency and prices at which we sell Shares. To the extent we sell Shares under the Purchase Agreement, we currently plan to use any proceeds therefrom for working capital, and other general corporate purposes.

There are no restrictions on future financings, rights of first refusal, participation rights, penalties, or liquidated damages in the Purchase Agreement. Alumni Capital has agreed not to cause, or engage in any manner whatsoever, any direct or indirect short selling or hedging of the Common Stock during certain periods.

Pursuant to the Purchase Agreement, we have agreed to file a registration statement with the SEC to register for resale under the Securities Act the Shares and the Warrant Shares that may be issued to Alumni Capital under the Purchase Agreement and upon exercise of the Warrants, respectively. The filing of the registration statement of which this prospectus forms a part was made to satisfy this obligation. The Purchase Agreement contains customary representations, warranties, conditions and indemnification obligations of the parties. The representations, warranties and covenants contained in such agreements were made only for purposes of such agreements and as of specific dates, were solely for the benefit of the parties to such agreements and may be subject to limitations agreed upon by the contracting parties.

We have the right to terminate the Purchase Agreement at any time, at no cost or penalty, upon written notice to Alumni Capital except after submitting a purchase notice and before delivering the related Warrant that is due and owed to Alumni Capital. Neither we nor Alumni Capital may assign or transfer its rights and obligations under the Purchase Agreement, and no provision of the Purchase Agreement may be modified or waived by the parties except in writing. We do not know what the purchase price for our Common Stock will be or whether there will occur an exception to the Exchange Cap and therefore cannot be certain as to the number of shares we might issue to Alumni Capital under the Purchase Agreement after the date of this prospectus. We are registering for resale under this prospectus 73,578,595 shares of Common Stock, which represents (i) 66,889,632 Shares that we may issue and sell to Alumni Capital under the Purchase Agreement and (ii) 6,688,963 Warrant Shares that are issuable upon exercise of the Warrants that we may issue to Alumni Capital in connection with any single fixed purchase under the Purchase Agreement. Depending on the market prices of our Common Stock at the time we elect to issue and sell Shares and Warrants to Alumni Capital under the Purchase Agreement, we may need to register for resale under the Securities Act additional shares of our Common Stock in order to receive aggregate gross proceeds equal to the full Investment Amount. If all of such 73,578,595 shares of Common Stock offered hereby were issued and outstanding as of the date of this prospectus, such shares would represent approximately 83.09% of the total number of outstanding shares of Common Stock.

Issuances of our Common Stock to Alumni Capital under the Purchase Agreement will not affect the rights or privileges of our existing stockholders, except that the economic and voting interests of each of our existing stockholders will be diluted as a result of any such issuance. Although the number of shares of our Common Stock that our existing stockholders own will not decrease, the shares of our Common Stock owned by our existing stockholders will represent a smaller percentage of our total outstanding shares of our Common Stock after any such issuance of shares of our Common Stock to Alumni Capital under the Purchase Agreement. There are substantial risks to our stockholders as a result of the sale and issuance of Common Stock to Alumni Capital under the Purchase Agreement. See “Risk Factors.”

Conditions to Commencement and for Delivery of Fixed Purchase Notices

Our ability to deliver purchase notices to Alumni Capital under the Purchase Agreement are subject to the satisfaction by us, of certain conditions, all of which are entirely outside of Alumni Capital’s control, including the following:

Alumni Capital shall not have received any notice from us that the registration statement, prospectus and/or any prospectus supplement or amendment thereto fails to meet the requirements of Section 5(b) or Section 10 of the Securities Act;

● the number of Shares and Warrants then to be purchased by Alumni Capital shall not exceed the number of such shares that, when aggregated with all other shares of Common Stock then beneficially or deemed beneficially owned by Alumni Capital would result in Alumni Capital owning more than the Beneficial Ownership Limitation;

● trading in the Common Stock shall not have been suspended by the SEC or the NYSE American, or otherwise halted for any reason, and the Common Stock shall have been approved for listing or quotation on and shall not have been delisted from or no longer quoted on the NYSE American;

● the issuance of the Shares and the Warrants shall not exceed the Exchange Cap if applicable (subject to appropriate adjustment for any stock dividend, stock split, stock combination, rights offerings, reclassification or similar transaction that proportionately decreases or increases the Common Stock) unless holders of a majority of our outstanding voting Common Stock that are present or represented by proxy at a meeting to effectuate the transactions contemplated by the Purchase Agreement, vote in favor of the issuance of all of the Shares and Warrants in excess the Exchange Cap (subject to appropriate adjustment for any stock dividend, stock split, stock combination, rights offerings, reclassification or similar transaction that proportionately decreases or increases the Common Stock), provided further that, the Exchange Cap will not apply solely to the extent that (and only for so long as) the purchase price shall equal or exceed the Minimum Price (as defined in the Purchase Agreement);

● the absence of any statute, rule, regulation, executive order, decree, ruling or injunction shall have been enacted, entered, promulgated or adopted by any court or governmental authority of competent jurisdiction that prohibits or directly and materially adversely affects any of the transactions contemplated by the Purchase Agreement, and no proceeding shall have been commenced that may have the effect of prohibiting or materially adversely affecting any of the transactions contemplated by the Purchase Agreement;

● the Common Stock must be DWAC eligible and not subject to a “DTC chill”;

● the issuance of the Shares shall not violate the shareholder approval requirements of the NYSE American;

● since our most recent filing with the SEC of any document required under the Securities Act or the Exchange Act, no event shall have occurred that had or is reasonably likely to have an effect on our business, operations, properties, or financial condition that is material and adverse to us and/or any condition, circumstance, or situation that would prohibit or otherwise materially interfere with our ability to enter into and perform our obligations under the Purchase Agreement; and

● all reports, schedules, registrations, forms, statements, information and other documents required to have been filed by us with the SEC pursuant to the reporting requirements of the Exchange Act shall have been filed with the SEC.

Termination of the Purchase Agreement

Unless earlier terminated as provided in the Purchase Agreement, the Purchase Agreement will terminate automatically on the earliest to occur of:

● December 31, 2026;

● the date on which Alumni Capital shall have purchased Shares for an aggregate purchase price of the Investment Amount; or

● the date on which we commence a voluntary bankruptcy case or any third party commences a bankruptcy proceeding against us, a custodian is appointed us in a bankruptcy proceeding for all or substantially all of its property, or we make a general assignment for the benefit of its creditors.

We have the right to terminate the Purchase Agreement at any time upon three days’ written notice, at no cost or penalty, except we cannot terminate after submitting a purchase notice and before delivering the related Warrant that is due and owed to Alumni Capital.

No Short-Selling or Hedging by Alumni Capital

Alumni Capital has agreed that neither it nor any of its affiliates shall engage in any direct or indirect short-selling our Common Stock during any time prior to the termination of the Purchase Agreement.

Effect of Performance of the Purchase Agreement on our Stockholders

All Shares registered in this offering that may be issued or sold by us to Alumni Capital under the Purchase Agreement are expected to be freely tradable. The resale by Alumni Capital of a significant number of Shares and Warrant Shares registered in this offering at any given time, or the perception that these sales may occur, could cause the market price of our Common Stock to decline and to be highly volatile. Sales of our Common Stock to Alumni Capital, if any, will depend upon market conditions and other factors to be determined by us. If and when we do sell Shares and Warrants to Alumni Capital, after Alumni Capital has acquired the Shares and/or exercised the Warrants, Alumni Capital may resell all, some or none of those Shares and Warrant Shares at any time or from time to time in its discretion. Therefore, sales to Alumni Capital by us under the Purchase Agreement may result in substantial dilution to the interests of other holders of our Common Stock. In addition, if we sell a substantial number of Shares and Warrants to Alumni Capital under the Purchase Agreement, or if investors expect that we will do so, the actual sales of Shares and Warrants or the mere existence of our arrangement with Alumni Capital may make it more difficult for us to sell equity or equity-related securities in the future at a time and at a price that we might otherwise wish to effect such sales. However, we have the right to control the timing and amount of any additional sales of Shares and Warrants to Alumni Capital, and the Purchase Agreement may be terminated by us at any time at our discretion without any cost to us, subject to certain conditions.

The following table sets forth the amount of gross proceeds we would receive from Alumni Capital from our sale of shares of Common Stock to Alumni Capital under the Purchase Agreement at varying purchase prices:

This prospectus relates to shares of Common Stock that may be offered and sold from time to time by Alumni Capital. We will not receive any proceeds from the resale of shares of Common Stock by Alumni Capital.

We may receive up to $20 million in aggregate gross proceeds if we issue to Alumni Capital Shares under the Purchase Agreement. We estimate that the net proceeds to us from the sale of Shares to Alumni Capital pursuant to the Purchase Agreement would be up to $19.9 million, assuming that we sell the full amount of our Common Stock that we have the right, but not the obligation, to sell to Alumni Capital under the Purchase Agreement, and after deducting other estimated fees and expenses. See “Plan of Distribution” elsewhere in this prospectus for more information. We may also receive up to $2.6 million if the Warrants are exercised for cash.

Any proceeds from the Selling Stockholder that we receive under the Purchase Agreement are currently expected to be used primarily for working capital and general corporate purposes. Pending these uses, we expect to invest the net proceeds in short-term, interest-bearing securities. We have broad discretion in determining how the proceeds of this offering will be used, and our discretion is not limited by the aforementioned possible uses. Our Board believes the flexibility in application of the net proceeds is prudent. As we are unable to predict the timing or amount of Shares that we may sell under the Purchase Agreement, we cannot specify with certainty all of the particular uses for the net proceeds that we will have from the sale of such shares. Accordingly, our management will have broad discretion in the application of the net proceeds. We may use the proceeds for purposes that are not contemplated at the time of this offering. It is possible that no Shares will be issued under the Purchase Agreement.

We will incur all costs associated with this prospectus and the registration statement of which it is a part.

DIVIDEND POLICY

We have never declared or paid any cash dividends on our Common Stock and we do not anticipate paying any cash dividends on our Common Stock in the foreseeable future. Investors should not purchase our Common Stock with the expectation of receiving cash dividends. The payment of dividends on our Common Stock, if any, in the future is within the discretion of our Board and will depend on our earnings, capital requirements and financial condition and other relevant facts. We currently intend to retain all future earnings, if any, to finance the development and growth of our business.

DESCRIPTION OF SECURITIES

General

The following description summarizes the most important terms of our capital stock. Because it is only a summary, it does not contain all the information that may be important to you. For a complete description of the matters set forth in this “Description of Securities,” you should refer to our amended and restated certificate of incorporation and amended and restated bylaws and investor rights agreement, which are included as exhibits to the registration statement of which this prospectus forms a part, and to the applicable provisions of Delaware law.

Our authorized capital stock consists of 100,000,000 shares of Common Stock, $0.0001 par value per share, and 10,000,000 shares of undesignated preferred stock, $0.0001 par value per share.

There are 14,979,354 shares of our Common Stock outstanding and no shares of our preferred stock outstanding as of the date of this prospectus. As of the date of this prospectus, we had 34 stockholders of record.

Common Stock

The holders of Common Stock are entitled to one vote for each share of Common Stock. The holders of Common Stock are entitled to any dividends that may be declared by the Board out of funds legally available for payment of dividends at such times and in such amounts as the Board in its discretion. In the event of any liquidation, dissolution or winding up of the Company, holders of Common Stock are entitled to receive the assets of the Company available for distribution to its stockholders ratably in proportion to the number of shares of Common Stock held by the holders of Common Stock. The holders of shares of Common Stock have no preemptive, conversion, subscription rights or cumulative voting rights.

Preferred Stock

As of the date of this prospectus, there are a total of 10,000,000 shares of undesignated preferred stock authorized for issuance, none of which are outstanding.

Our Board is authorized, without further action by our stockholders, to provide from time to time out of the unissued shares of preferred stock for one or more series of preferred stock, and with respect to each such series, to fix the number of shares constituting such series and the designation of such series, the powers (including voting powers), if any, of the shares of such series and the preferences and relative, participating, optional, special or other rights, if any, and the qualifications, limitations, or restrictions, if any, of the shares of such series. The issuance of our preferred stock could adversely affect the voting power of holders of our Common Stock and the likelihood that such holders will receive dividend payments and payments upon liquidation. In addition, the issuance of preferred stock could have the effect of delaying, deferring, or preventing a change of control or other corporate action.

Warrants included in this Offering

The following is a summary of certain terms and provisions of the Warrants that are being offered hereby and is not complete and is subject to, and qualified in its entirety by, the provisions of the Warrants, the form of which is filed as an exhibit to the registration statement of which this prospectus forms a part. Prospective investors should carefully review the terms and provisions of the form of Warrants for a complete description of the terms and conditions of the Warrants.

Duration and Exercise Price

Each Warrant offered hereby will have an exercise price equal to 130% of the price per share of Common Stock paid upon the closing for which the Warrant is issued. The exercise of the Warrant will be subject to stockholder approval and expire five years after issuance. The Warrants may be exercised via cashless exercise if there is no effective registration statement, or current prospectus available for, the resale of the Warrant Shares.

Exercisability

The Warrants will be exercisable upon stockholder approval and at the option of each holder, in whole or in part, by delivering to us a duly executed exercise notice accompanied by payment in full for the number of shares of our Common Stock purchased upon such exercise (except in the case of a cashless exercise as discussed below). A holder (together with its affiliates) may not exercise any portion of such holder’s Warrants to the extent that the holder would own more than 9.99%

Cashless Exercise

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

Fundamental Transactions

In the event of any fundamental transaction, as described in the Warrants and generally including any merger or consolidation with or into another entity, sale of all or substantially all of our assets, tender offer or exchange offer, or reclassification of our Common Stock, the Company shall, if the Company is not the survivor (the “Successor Entity”), cause any Successor Entity to assume in writing all of the obligations of the Company under the Warrant pursuant to written agreements in form and substance reasonably satisfactory to and approved by the holder prior to such fundamental transaction and shall, at the option of the holder, deliver to the holder in exchange for this Warrant a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to this Warrant which is exercisable for a corresponding number of shares of capital stock of such Successor Entity (or its parent entity) equivalent to the shares of Common Stock acquirable and receivable upon exercise of this Warrant (without regard to any limitations on the exercise of this Warrant) prior to such fundamental transaction, and with an exercise price which applies the exercise price hereunder to such shares of capital stock (but taking into account the relative value of the shares of Common Stock pursuant to such fundamental transaction and the value of such shares of capital stock, such number of shares of capital stock and such exercise price being for the purpose of protecting the economic value of this Warrant immediately prior to the consummation of such fundamental transaction), and which is reasonably satisfactory in form and substance to the holder. Upon the occurrence of any such fundamental transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such fundamental transaction, the provisions of this Warrant and referring to the “Company” shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the Company under this Warrant with the same effect as if such Successor Entity had been named as the Company herein.

Transferability

Subject to applicable laws, the Warrants may be transferred at the option of the holder upon surrender of the Warrants to us together with the appropriate instruments of transfer.

Right of Participation

For a period of 12 months from the issuance of the Warrants, the Company shall not, and shall cause each of its subsidiaries not to, (x) contract with any party for the issuance of any indebtedness that includes an equity component or that is convertible into, exercisable into or exchangeable for equity securities of the Company or any of its subsidiaries or equity financing, or (y) issue any equity securities of the Company or any of its subsidiary or securities convertible, exchangeable or exercisable into or for equity securities of the Company or any of its subsidiaries (including any indebtedness that includes an equity component or that is convertible into, exercisable into or exchangeable for equity securities of the Company or any of its subsidiaries) (a “Future Offering”), except pursuant to certain excluded issuances listed in the Warrants and “at-the-market” offerings under Rule 415(a)(4) of the Securities Act (none of which shall be considered Future Offerings and to which the Holder Purchase Option (as defined below) shall not apply), unless it shall have first delivered to the holder written notice (the “Future Offering Notice”) describing generally the proposed Future Offering and providing the holder an option (the “Holder Purchase Option”) to purchase up to a number of securities to be issued in such Future Offering equal to the product (such product, the holder’s “Allocation Portion”) of (A) a fraction, (1) the numerator of which is the sum of the number of shares of Common Stock acquired by the holder under Purchase Notices (as defined in the Purchase Agreement) and the number of Warrant Shares issued, and (2) the denominator of which is the number of shares of Common Stock issued and outstanding on the date of the Future Offering Notice, and (B) the total amount of securities to be issued in such Future Offering.

Fractional Shares

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

Trading Market

There is no established trading market for the Warrants, and we do not expect an active trading market to develop. We do not intend to apply to list the Warrants on any securities exchange or other trading market. Without a trading market, the liquidity of the Warrants will be extremely limited. The shares of Common Stock issuable upon exercise of the Warrants are currently traded on the NYSE American under the symbol “AZTR”.

Right as a Stockholder

Except as otherwise provided in the Warrants or by virtue of the holder’s ownership of shares of our Common Stock, such holder of Warrants does not have the rights or privileges of a holder of our Common Stock, including any voting rights, until such holder exercises such holder’s Warrants. The Warrants provide that holders have the right to participate in distributions or dividends paid on our shares of Common Stock.

Waivers and Amendments

No term of the Warrants may be amended or waived without the written consent of the holder and the Company.

Registration Rights

Certain holders of our Common Stock, or their permitted transferees, are entitled to the registration rights described below. The registration of shares of our Common Stock pursuant to the exercise of registration rights described below would enable the holders to sell these shares without restriction under the Securities Act when the applicable registration statement is declared effective. We will pay the registration expenses, other than the underwriting discounts and commissions, of the shares registered pursuant to the registrations described below. The registration rights described below will expire upon the earlier of June 20, 2026 or when all investors, considered with their affiliates, can sell all of their shares in a three-month period under Rule 144.

Convertible Preferred Stock Registration Rights. In connection with our convertible preferred stock financings, we entered into an investor rights agreement, as amended, pursuant to which we have granted the purchasers of our convertible preferred stock certain demand and piggyback registration rights. Those parties beneficially hold approximately 217,082 shares of our Common Stock, including 5,612 shares of our Common Stock issuable upon exercise of warrants issued to the parties in connection with our 2018 placement of our unsecured convertible promissory notes and our 2019 placement of Series A-1 convertible preferred shares.

Pursuant to the investor rights agreement, we are required, upon the written request by the holders of at least 50% of the shares that are entitled to registration rights under the investor rights agreement, to register, as soon as practicable, all or a portion of these shares for public resale. We are required to effect two demand registrations pursuant to a registration statement on Form S-1. Subject to our eligibility to use a registration statement on Form S-3, we are required to effect an unlimited number of demand registrations pursuant to Form S-3, provided such requests for registration be for an aggregate offering price, net of the underwriting discounts and commissions, equal or greater than $1 million. Pursuant to the investor rights agreement, we have also granted to the piggyback registration rights and demand registration rights. These demand and piggyback registration rights terminate as to each investor when their shares subject to the registration rights agreement may be sold by the investor pursuant to Rule 144 under the Securities Act without regard to both the volume limitations for sales as provided in Rule 144.

On July 1, 2024, we filed with the SEC a registration statement on Form S-3 to register the resale of the 217,082 shares of Common Stock held by the stockholders holding demand registration rights.

Underwriter Registration Rights. In connection with our IPO and February 2024 public offering, we issued to the representative of the underwriters or its designees warrants, referred to as the Representative’s Warrants, to purchase up to a total of 2,000 shares and 22,222 shares of our Common Stock, respectively. The Representative’s Warrants provide for registration rights (including a one-time demand registration right and unlimited piggyback rights) consistent with FINRA Rule 5110.05. The demand for registration may be made at any time beginning on the initial exercise date of the Representative’s Warrants and expiring on the fifth anniversary of the date of the public offering prospectus to which the warrants relate in accordance with FINRA Rule 5110(g)(8)(C). In addition to the one-time demand registration right, the Representative’s Warrants have unlimited piggyback rights, for a period of no more than two years from the initial exercise date of the Representative’s Warrants in accordance with FINRA Rule 5110(g)(8)(D).

January 2025 Offering. In connection with the offering of securities pursuant to our shelf registration statement on Form S-3 that we completed in January 2025, we issued to the placement agent or its designees warrants, referred to as the Placement Agent Warrants, to purchase up to a total of 194,311 shares of our Common Stock. The Placement Agent Warrants provide for registration rights provide for registration rights (including a one-time demand registration right and unlimited piggyback rights) consistent with FINRA Rule 5110.05. The demand for registration may be made at any time beginning on the initial exercise date of the Placement Agent Warrants and expiring on the fifth anniversary of the date of the public offering prospectus to which the warrants relate in accordance with FINRA Rule 5110(g)(8)(C).

Anti-Takeover Effects of Certain Provisions of Delaware Law and Our Charter Documents

The following is a summary of certain provisions of Delaware law and our amended and restated certificate of incorporation and amended and restated bylaws. This summary does not purport to be complete and is qualified in its entirety by reference to the corporate law of Delaware and our amended and restated certificate of incorporation and amended and restated bylaws.

Delaware Law

We are subject to Section 203 of the Delaware General Corporation Law, an anti-takeover law. In general, Section 203 prohibits a Delaware corporation from engaging in any business combination (as defined below) with any interested stockholder (as defined below) for a period of three years following the date that the stockholder became an interested stockholder, unless:

	●	prior to that date, the board of directors of the corporation approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder;
	●	upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the number of shares of voting stock outstanding (but not the voting stock owned by the interested stockholder) those shares owned by persons who are directors and officers and by excluding employee stock plans in which employee participants do not have the right to determine whether shares held subject to the plan will be tendered in a tender or exchange offer; or
	●	on or subsequent to that date, the business combination is approved by the board of directors of the corporation and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least 66 2/3% of the outstanding voting stock that is not owned by the interested stockholder.

Section 203 defines “business combination” to include the following:

	●	any merger or consolidation involving the corporation and the interested stockholder;
	●	any sale, transfer, pledge or other disposition of 10% or more of the assets of the corporation involving the interested stockholder;
	●	subject to certain exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested stockholder;
	●	subject to limited exceptions, any transaction involving the corporation that has the effect of increasing the proportionate share of the stock of any class or series of the corporation beneficially owned by the interested stockholder; or
	●	the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits provided by or through the corporation.

In general, Section 203 defines an interested stockholder as any entity or person beneficially owning 15% or more of the outstanding voting stock of the corporation, or who beneficially owns 15% or more of the outstanding voting stock of the corporation at any time within a three-year period immediately prior to the date of determining whether such person is an interested stockholder, and any entity or person affiliated with or controlling or controlled by any of these entities or persons.

Our Charter Documents

Our charter documents include provisions that could have the effect of discouraging others from making tender offers for our shares and may have the effect of deterring hostile takeovers or delaying changes in our control or management. These provisions are intended to enhance the likelihood of continued stability in the composition of our Board and its policies and to discourage certain types of transactions that may involve an actual or threatened acquisition of us. These provisions are also designed to reduce our vulnerability to an unsolicited acquisition proposal and to discourage certain tactics that may be used in proxy fights. However, such provisions may have the effect of discouraging, delaying or preventing a change in control or an unsolicited acquisition proposal that a stockholder might consider favorable, including a proposal that might result in the payment of a premium over the market price for the shares held by our stockholders. Certain of these provisions are summarized in the following paragraphs.

Effects of authorized but unissued Common Stock and preferred stock. One of the effects of the existence of authorized but unissued Common Stock and preferred stock may be to enable our Board to make more difficult or to discourage an attempt to obtain control of our Company by means of a merger, tender offer, proxy contest or otherwise, and thereby to protect the continuity of management. If, in the due exercise of its fiduciary obligations, the Board were to determine that a takeover proposal was not in our best interest, such shares could be issued by the Board without stockholder approval in one or more transactions that might prevent or render more difficult or costly the completion of the takeover transaction by diluting the voting or other rights of the proposed acquirer or insurgent stockholder group, by putting a substantial voting block in institutional or other hands that might undertake to support the position of the incumbent Board, by effecting an acquisition that might complicate or preclude the takeover, or otherwise.

Cumulative Voting. Our amended and restated certificate of incorporation does not provide for cumulative voting in the election of directors, which would allow holders of less than a majority of the stock to elect some directors.

Vacancies. Our amended and restated bylaws provide that all vacancies may be filled by the affirmative vote of a majority of directors then in office, even if less than a quorum.

Special Meeting of Stockholders and Stockholder Action by Written Consent. A special meeting of stockholders may only be called by our Board or the chairperson of our Board. All stockholder actions must be effected at a duly called meeting of stockholders and not by written consent.

Advance Notice Provisions. Our amended and restated bylaws provide advance notice procedures for stockholders seeking to bring business before our annual meeting of stockholders or to nominate candidates for election as directors at our annual meeting of stockholders. Our amended and restated bylaws will also specify certain requirements regarding the form and content of a stockholder’s notice. These provisions might preclude our stockholders from bringing matters before our annual meeting of stockholders or from making nominations for directors at our annual meeting of stockholders if the proper procedures are not followed. We expect that 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.

Choice of Forum. Our amended and restated certificate of incorporation and amended and restated bylaws will provide that the Court of Chancery of the State of Delaware will be the exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting a breach of fiduciary duty; any action asserting a claim against us arising pursuant to the Delaware General Corporation Law, our amended and restated certificate of incorporation or our bylaws; or any action asserting a claim against us that is governed by the internal affairs doctrine.

Transfer Agent and Registrar

The transfer agent and registrar for our shares of Common Stock is VStock Transfer, LLC. The transfer agent and registrar’s address is 18 Lafayette Place, Woodmere, New York 11598.

National Securities Exchange Listing

Our Common Stock is listed on the NYSE American under the symbol “AZTR.”

Selling Stockholder

This prospectus relates to the possible resale from time to time by Alumni Capital of any or all of the Shares and Warrant Shares that may be issued by us to Alumni Capital under the Purchase Agreement and upon exercise of the Warrants, respectively. For additional information regarding the issuance of Common Stock covered by this prospectus, see the section titled “The Alumni Capital Transaction” above. We are registering the shares of Common Stock pursuant to the provisions of the Purchase Agreement we entered into with Alumni Capital on April 24, 2025, in order to permit the Selling Stockholder to offer the Shares and the Warrant Shares for resale from time to time. Except for the transactions contemplated by the Purchase Agreement, Alumni Capital has not had any material relationship with us within the past three years. As used in this prospectus, the term “Selling Stockholder” means Alumni Capital LP.

The table below presents information regarding the Selling Stockholder and the shares of Common Stock that it may offer from time to time under this prospectus. This table is prepared based on information supplied to us by the Selling Stockholder, and reflects holdings as of April 25, 2025. The number of shares in the column “Maximum Number of Shares of Common Stock to be Offered Pursuant to this Prospectus” represents all of the shares of Common Stock that the Selling Stockholder may offer under this prospectus. The Selling Stockholder may sell some, all or none of its shares of Common Stock in this offering. We do not know how long the Selling Stockholder will hold the shares of Common Stock before selling them, and we currently have no agreements, arrangements or understandings with the Selling Stockholder regarding the sale of any of the shares of Common Stock.

Beneficial ownership is determined in accordance with Rule 13d-3(d) promulgated by the SEC under the Exchange Act, and includes shares of Common Stock with respect to which the Selling Stockholder has voting and investment powers. The percentage of shares of Common Stock beneficially owned by the Selling Stockholder prior to the offering shown in the table below is based on an aggregate of 14,979,354 shares of our Common Stock outstanding on April 25, 2025. Because the purchase price of the Shares issuable under the Purchase Agreement is determined on each purchase date, and the exercise price of the Warrants, based on such purchase price, the number of Shares and Warrant Shares that may actually be sold by us under the Purchase Agreement and be issuable upon exercise of the Warrants, respectively, may be fewer than those being offered by this prospectus. The fourth column assumes the sale of all of the Shares offered by the Selling Stockholder pursuant to this prospectus.

The securities may be sold or distributed from time to time by the Selling Stockholder directly to one or more purchasers or through brokers, dealers, or underwriters who may act solely as agents at market prices prevailing at the time of sale, at prices related to the prevailing market prices, at negotiated prices, or at fixed prices, which may be changed. The sale of the securities offered by this prospectus could be effected in one or more of the following methods:

●	ordinary brokers’ transactions;

●	transactions involving cross or block trades;

●	through brokers, dealers, or underwriters who may act solely as agents;

Alumni Capital is an “underwriter” within the meaning of Section 2(a)(11) of the Securities Act.

Alumni Capital has informed us that it intends to use one or more registered broker-dealers to effectuate all sales, if any, of our Common Stock and Warrants that it may in the future acquire from us pursuant to the Purchase Agreement. Such sales will be made at prices and at terms then prevailing or at prices related to the then current market price. Each such registered broker-dealer will be an underwriter within the meaning of Section 2(a)(11) of the Securities Act. Alumni Capital has informed us that each such broker-dealer will receive commissions from Alumni Capital that will not exceed customary brokerage commissions.

Broker-dealers engaged by the Selling Stockholder may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the Selling Stockholder (or, if any broker-dealer acts as agent for the purchaser of securities, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with FINRA Rule 2121; and in the case of a principal transaction a markup or markdown in compliance with FINRA Rule 2121.

We may from time to time file with the SEC one or more supplements to this prospectus or amendments to the registration statement of which this prospectus forms a part to amend, supplement or update information contained in this prospectus, including, if and when required under the Securities Act, to disclose certain information relating to a particular sale of shares offered by this prospectus by the Selling Stockholder, including the names of any brokers, dealers, underwriters or agents participating in the distribution of such shares by the Selling Stockholder, any compensation paid by the Selling Stockholder to any such brokers, dealers, underwriters or agents, and any other required information.

We will pay the expenses incident to the registration under the Securities Act of the offer and sale of the shares of our Common Stock covered by this prospectus by the Selling Stockholder.

We also have agreed to indemnify Alumni Capital and certain other persons against certain liabilities in connection with the offering of shares of our Common Stock offered hereby, including liabilities arising under the Securities Act or, if such indemnity is unavailable, to contribute amounts required to be paid in respect of such liabilities. Alumni Capital has agreed to indemnify us against liabilities under the Securities Act that may arise from certain written information furnished to us by Alumni Capital specifically for use in this prospectus or, if such indemnity is unavailable, to contribute amounts required to be paid in respect of such liabilities. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers, and controlling persons, we have been advised that in the opinion of the SEC this indemnification is against public policy as expressed in the Securities Act and is therefore, unenforceable.

We estimate that the total expenses for the offering will be approximately $100,000.

Alumni Capital has represented to us that at no time prior to the date of the Purchase Agreement has Alumni Capital or its agents, representatives or affiliates engaged in or effected, in any manner whatsoever, directly or indirectly, any short sale (as such term is defined in Rule 200 of Regulation SHO of the Exchange Act) of our Common Stock, which establishes a net short position with respect to our Common Stock. Alumni Capital has agreed that during the term of the Purchase Agreement, neither Alumni Capital, nor any of its agents, representatives or affiliates will enter into or effect, directly or indirectly, any of the foregoing transactions.

We have advised the Selling Stockholder that it is required to comply with Regulation M promulgated under the Exchange Act. With certain exceptions, Regulation M precludes the Selling Stockholder, any affiliated purchasers, and any broker-dealer or other person who participates in the distribution from bidding for or purchasing, or attempting to induce any person to bid for or purchase any security which is the subject of the distribution until the entire distribution is complete. Regulation M also prohibits any bids or purchases made in order to stabilize the price of a security in connection with the distribution of that security. All of the foregoing may affect the marketability of the securities offered by this prospectus.

This offering will terminate on the date that all shares of our Common Stock offered by this prospectus have been sold by the Selling Stockholder.

Our Common Stock is currently listed on the NYSE American under the symbol “AZTR.”

Thompson Hine LLP, New York, New York, will pass upon the validity of the Shares and the Warrant Shares offered hereby.

Item 14. Indemnification of Directors and Officers.

The following summary is qualified in its entirety by reference to the complete text of any statutes referred to below and the Second Amended and Restated Certificate of Incorporation, or Certificate of Incorporation, of Azitra, Inc., a Delaware corporation.

Section 145 of the General Corporation Law of the State of Delaware (the “DGCL”) permits a Delaware corporation to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe the person’s conduct was unlawful.

In the case of an action by or in the right of the corporation, Section 145 of the DGCL permits a Delaware corporation to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees) actually and reasonably incurred by the person in connection with such action, suit or proceeding if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses that the Court of Chancery or such other court shall deem proper.

II-1

Section 145 of the DGCL also permits a Delaware corporation to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against such person and incurred by such person in any such capacity, or arising out of such person’s status as such, whether or not the corporation would have the power to indemnify such person against such liability under Section 145 of the DGCL.

Our Certificate of Incorporation states that to the fullest extent permitted by the DGCL our directors shall not be personally liable to us or to our stockholders for monetary damages for breach of fiduciary duty as a director. If the DGCL is amended after the date hereof to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of our directors shall be eliminated or limited to the fullest extent permitted by the DGCL, as so amended.

Our Certificate of Incorporation requires us, to the fullest extent permitted by applicable law, to provide indemnification of (and advancement of expenses to) our directors and officers, and authorizes us, to the fullest extent permitted by applicable law, to provide indemnification of (and advancement of expenses to) to other employees and agents (and any other persons to which the DGCL permits us to provide indemnification) through bylaw provisions, agreements with such directors, officers, employees, agents or other persons, vote of stockholders or disinterested directors or otherwise, subject only to limits created by the DGCL with respect to actions for breach of duty to our corporation, our stockholders and others.

Our Certificate of Incorporation provides that we shall, to the maximum extent and in the manner permitted by the DGCL, indemnify each of our directors, officers and all other persons we have the power to indemnify under Section 145 of the DGCL against expenses (including attorneys’ fees), judgments, fines, settlements and other amounts actually and reasonably incurred in connection with any proceeding, arising by reason of the fact that such person is or was a director of the Company. We may maintain insurance, at our expense, to protect the Company and any of our directors, officers, employees or agents against any such expense, liability or loss, whether or not we have the power to indemnify such person.

We have entered into indemnification agreements with each of our directors and executive officers that may be broader than the specific indemnification provisions contained in the DGCL. These indemnification agreements require us, among other things, to indemnify our directors and executive officers against liabilities that may arise by reason of their status or service. These indemnification agreements also require us to advance all expenses incurred by the directors and executive officers in investigating or defending any such action, suit, or proceeding. We believe that these agreements are necessary to attract and retain qualified individuals to serve as directors and executive officers.

Prior to the closing of this offering, we plan to enter into an underwriting agreement, which will provide that the underwriters are obligated, under some circumstances, to indemnify our directors, officers and controlling persons against specified liabilities.

Item 15. Recent Sales of Unregistered Securities.

The following list sets forth information regarding all unregistered securities sold by us over the three-year period preceding the date of the prospectus that forms a part of this registration statement.

In January 2022, we sold to one investor an unsecured convertible promissory note in the principal amount of $1,000,000. In January 2023, the principal amount of the note, along with all accrued interest, was converted into 23,432 shares of our Series B convertible preferred stock. Subsequently, these shares were converted into Common Stock upon the consummation of the IPO.

II-2

In September 2022, we conducted the placement of our unsecured convertible promissory notes in the aggregate principal amount of $4.35 million to five investors. The principal amount of the notes, along with all accrued and unpaid interest thereunder, converted into 61,534 shares of our Common Stock upon the consummation of the IPO.

No underwriters were involved in the foregoing issuances of securities. We believe the offers, sales and issuances of the above securities by us were exempt from registration under the Securities Act by virtue of Section 4(a)(2) of the Securities Act and Rule 506 thereunder as transactions not involving a public offering. All of the investors were accredited investors as such term is defined in Rule 501 under the Securities Act. The recipients of the securities in each of these transactions represented their intentions to acquire the securities for investment only and not with a view to or for sale in connection with any distribution thereof, and appropriate legends were placed upon the stock certificates, notes and warrants issued in these transactions. All recipients had adequate access, through their relationships with us, to information about our Company. The sales of these securities were made without any general solicitation or advertising.

On January 14, 2025, the Company entered into a placement agency agreement (the “Placement Agency Agreement”) with Maxim Group LLC (the “Placement Agent”) in connection with the offer and sale to investors of up to 4,857,780 shares (the “Shares”) of the Company’s Common Stock, at an offering price of $0.30 per Share (the “Offering”). In connection with the Offering, the Company entered into a securities purchase agreement (the “Purchase Agreement”) with certain of the purchasers in the Offering. The aggregate gross proceeds to the Company from the Offering were approximately $1.5 million, before deducting placement agent fees and other estimated offering expenses. The Offering closed on January 16, 2025.

The Placement Agent acted as the Company’s exclusive placement agent in the Offering. Pursuant to the terms of the Placement Agency Agreement, the Company has agreed to pay the Placement Agent a cash fee equal to 7.0% of the aggregate gross proceeds raised in the Offering. The Company also agreed to reimburse the Placement Agent for certain expenses. As additional compensation, the Company agreed to issue to the Placement Agent (or its designees) an unregistered warrant (the “Placement Agent Warrant”) to purchase an aggregate of 194,311 shares of Common Stock (the “Placement Agent Warrant Shares”), which represents 4.0% of the aggregate number of Shares sold in the Offering, at an exercise price per share equal to 125% of the offering price of each Share, or $0.375. The Placement Agent Warrants are exercisable six (6) months from the date of issuance and expire five years from the commencement of sales in this Offering. The Placement Agent Warrant may be exercisable via “cashless exercise” in certain circumstances.

The Placement Agent Warrants and the shares of Common Stock issuable upon exercise of the Placement Agent Warrants have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or the securities laws of any state, and are being offered and sold in reliance on the exemption from registration under the Securities Act afforded by Section 4(a)(2) under the Securities Act and Regulation D promulgated thereunder as transactions by an issuer not involving any public offering.

On February 6, 2025, the Company closed an offering of 2,495,518 shares (the “February 2025 Shares”) of the Company’s Common Stock to certain investors (the “Investors”) pursuant to the Securities Purchase Agreement (the “SPA”) dated February 4, 2025, between the Company and the Investors, as amended on February 5, 2025. On February 6, 2025, in connection with the Investors’ agreement to enter into the amendment to the SPA, the Company and the Investors entered into a letter agreement (the “Letter Agreement”), pursuant to which the Company will (i) issue the Investors warrants to purchase up to 2,245,967 shares of Common Stock, in the aggregate (the “February 2025 Warrants”), and (ii) grant the investors a right for two years from the closing date of the Letter Agreement, to participate in future financings of the Company in an aggregate amount equal to 50% of such financings. Pursuant to the terms of the Letter Agreement, the Company must file a registration statement covering the issuance of the shares Common Stock underlying the February 2025 Warrants and use its best efforts to cause the registration statement to become effective by the six-month anniversary of the closing of the Letter Agreement. The February 2025 Warrants are exercisable on the six-month and one day anniversary of their issuance, and their exercise price is equal to the greater of the (i) book value or (ii) market value of the Common Stock as determined under NYSE American Rules. The February 2025 Warrants and the shares of Common Stock issuable upon exercise of the February 2025 Warrants have not been registered under the Securities Act, or the securities laws of any state, and are being offered and sold in reliance on the exemption from registration under the Securities Act afforded by Section 4(a)(2) under the Securities Act and/or Regulation D promulgated thereunder as transactions by an issuer not involving any public offering.

Item 17. Undertakings.

The undersigned registrant hereby undertakes to provide to the underwriter at the closing specified in the underwriting agreements, certificates in such denominations and registered in such names as required by the underwriters to permit prompt delivery to each purchaser.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

The undersigned registrant hereby undertakes:

(1)

To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933, as amended, or the Securities Act;

ii.

 To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

iii.

To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;
provided, however, that paragraphs (i), (ii) and (iii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934, as amended, or the Exchange Act, that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is a part of the registration statement.

(2)

That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

II-6

(3)

To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4)

That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness.
