**Company Overview** 

On October 10, 2024, we announced our continued progress and evaluation of our internally developed small molecule oral obesity program. The aim of this program is to develop a drug for obesity with a differentiated profile relative to currently marketed and in development oral and injectable products.

We have also operated as a clinical-stage oncology-focused cell therapy company developing adoptive TCR-T cell therapy, designed to treat multiple solid tumor types in large cancer patient populations with unmet clinical needs. On August 14, 2023, we announced a strategic reprioritization of our business and wind down of our TCR-T Library Phase 1/2 Trial.

In connection with the reprioritization, we reduced our workforce during the third and fourth quarters of 2023, and we continue working to reduce costs in order to extend our cash runway. We continue to explore strategic alternatives, including, but not limited to, an acquisition, merger, reverse merger, sale of assets, strategic partnerships, capital raises or other transactions.

We have not generated any product revenue and have incurred significant net losses in each year since our inception. For the six months ended June 30, 2025, we had a net loss of $2.1 million, and as of June 30, 2025, we have incurred approximately $922.6 million of accumulated deficit since our inception in 2003. We expect to continue to incur significant operating expenditures and net losses for the foreseeable future.

***Small Molecule Oral Obesity Program***

We are advancing our internally developed, preclinical small molecule program for the treatment of obesity and related metabolic disorders. This program focuses on discovering and developing novel, orally administered therapeutics with the potential for a differentiated and complementary profile compared to currently available therapies. While other pipeline therapies for obesity explore alternative hormonal pathways such as amylin or dual GIP/GLP-1 receptor agonism, our approach is focused on a non-hormonal mechanism of action. The program seeks to develop an oral therapeutic with the potential to address certain limitations of existing hormonal therapies, including the potential for preservation of lean muscle mass during weight loss and an improved tolerability profile.

During the fourth quarter of 2024, we engaged a contract development and manufacturing organization (CDMO) to synthesize active pharmaceutical ingredients (APIs) for our product candidates. We have since initiated a portfolio of preclinical studies to evaluate these product candidates. Initial in vitro characterization studies conducted by a contract research organization (CRO) encountered methodological issues related to the assay, which prevented the generation of conclusive data. This CRO has since completed the necessary method development to resolve these issues, and these studies are being repeated. In parallel, we have conducted an in vivo pharmacokinetic (PK) study of our product candidate ALN1003 and have initiated a pilot in vivo proof-of-concept (PoC) study of ALN1003 in a diet-induced obesity (DIO) mouse model.

------

Collectively, these ongoing studies are designed to assess our candidates' effects on key biological pathways implicated in metabolic disease, including receptor binding, lipid accumulation, food consumption, weight loss, and the expression of genes related to thermogenesis and energy expenditure. We anticipate initial data from these ongoing in vitro and in vivo studies will be available no later than the fourth quarter of 2025. These data are intended to inform the future development strategy for our product candidates and guide indication selection.

The advancement of this program is subject to numerous risks and uncertainties inherent in early-stage drug development. Subject to favorable data from these preclinical studies and our ability to secure additional capital, we plan to advance a selected development candidate into formal investigational new drug (IND)-enabling studies. We intend to actively explore strategic financing and collaboration opportunities to fund the continued development of this program.

**Obesity Market** 

Obesity remains one of the most pressing public health challenges globally, with rates continuing to rise across many regions, particularly in the United States, Europe, and parts of Asia. It is closely linked to a range of comorbid conditions, including type 2 diabetes, cardiovascular diseases, and certain cancers, which exacerbates the overall healthcare burden. The obesity market is seeing increased attention, driven by growing awareness, better treatment options, and emerging scientific breakthroughs.

The global obesity market is experiencing rapid growth. Globally, the market size for branded obesity drugs was $6 billion in 2023 and is estimated that it will reach $105.0 billion by 2030. This growth is fueled by the rising obesity prevalence, evolving patient demographics, and increasing demand for effective weight-management solutions. The shift toward more personalized treatments and the need for long-term weight management are key drivers of this growth.

The current treatment landscape for obesity consists of a combination of lifestyle interventions, pharmaceuticals, and surgical options. Lifestyle interventions—dietary changes and physical activity—are the first-line treatment for most individuals, but many struggle to achieve and maintain significant weight loss through these methods alone.

Traditional weight-loss medications (e.g., OrlistatTM) are still used, though their side effects and modest results have limited their appeal. Newer drugs, like GLP-1 receptor agonists (e.g., OzempicTM, WegovyTM), are quickly becoming the gold standard in the market. These drugs, which mimic the action of gut hormones to promote satiety and reduce appetite, have shown remarkable efficacy in clinical trials and are significantly improving patient outcomes.

The success of GLP-1s has led to a surge in interest from both pharmaceutical companies and patients. However, issues such as high cost, insurance reimbursement, and potential long-term side effects remain areas of concern.

The future of the obesity market is promising, with new therapies, enhanced patient targeting, and continued scientific breakthroughs on the horizon. As the global obesity epidemic continues to grow, demand for more effective and affordable treatments will likely continue to rise. However, success will depend on overcoming challenges related to cost, access, and patient adherence. Advancements in personalized medicine, non-invasive treatments, and innovative drug mechanisms will shape the next phase of the obesity treatment landscape.

The obesity market today is vibrant and expanding, but still in need of accessible, scalable, and sustainable solutions to effectively manage this complex and widespread health issue.

***Historical Development and Achievements in Cancer Therapeutics***

We previously focused on developing TCR-T cell therapies for solid tumors using our non-viral Sleeping Beauty platform and hunTR<sup>®</sup> TCR discovery platform. Key milestones included:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• TCR-T Library Phase 1/2 Trial (2022-2023): Treated eight patients with
solid tumors (e.g., pancreatic, colorectal, lung). The trial showed TCR-T cells were well-tolerated, with no dose-limiting toxicities or neurotoxicity. Cytokine release syndrome (grades 1-3) resolved with standard care. One non-small cell lung cancer patient achieved a partial response (13% response rate), and six others had stable disease (87% disease
control rate), establishing proof-of-concept that Sleeping Beauty TCR-T cells can result in objective clinical responses an
recognize established tumors *in vivo*.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• hunTR<sup>®</sup> Platform: Identified proprietary TCRs targeting
driver mutations (KRAS, TP53, others) and various HLAs, expanding the TCR library for potential patient treatment.

In August 2023, however, due to substantial development costs and a challenging financing environment, we announced a strategic reprioritization, including the wind-down of our TCR-T Library Phase 1/2 Trial and cessation of further clinical development of TCR-T programs. This involved:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Workforce reductions (approximately 95% by the end of 2023) and cost-cutting measures to extend cash runway.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Termination of key licenses and agreements:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• NCI patent license (effective December 26, 2023), after internally developing proprietary TCRs via hunTR
targeting similar mutations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• NCI CRADA (effective October 13, 2023).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Precigen exclusive license (fully terminated October 4, 2024, following an amendment in April 2023 that
eliminated royalty/milestone obligations).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Trial close-out activities, including internal processes, with ongoing
costs for long-term follow-up and regulatory obligations.

As a result, research and development expenses related to cancer programs have significantly declined, from $11.7 million for the six months ended June 30, 2023, to $0.3 million for the same period in 2025, reflecting the shift away from active oncology development.

We are actively exploring strategic alternatives to maximize stockholder value, including but not limited to acquisitions, mergers, reverse mergers, asset sales, strategic partnerships, or capital raises. These may involve monetizing cancer-related assets, such as out-licensing the TCR library or hunTR platform. We have engaged Cantor Fitzgerald & Co. as a strategic advisor for this process. However, there are no assurances that any transaction will be consummated, and failure to do so could lead to further operational curtailment or dissolution. Our primary focus has shifted to our preclinical small-molecule obesity and metabolic disorder program, with ongoing preclinical *in vitro* and *in vivo* studies.

**Selected Risks Related to our Business**

Our business is subject to numerous risks, including risks that may prevent us from achieving our business objectives or may adversely affect our business, financial condition, results of operations, cash flows and prospects that you should consider before making an investment decision. Some of the more significant risks and uncertainties relating to an investment in our company are listed below. These risks are more fully described in the section titled "*Risk Factors*" in this prospectus and in Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2024, and in Part II, Item 1A of our Quarterly Reports on Form 10-Q for the fiscal quarters ended March 31, 2025 and June 30, 2025, which are incorporated by reference into this prospectus.

------

Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also impair our business operations. You should be able to bear a complete loss of your investment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our strategic reprioritization may not be successful, may not yield the desired results and we may be
unsuccessful in identifying and implementing any strategic transaction.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• If a strategic transaction is not consummated, our board of directors ()"*Board*") may decide to
pursue a dissolution and liquidation. In such an event, the amount of cash available for distribution to our stockholders will depend heavily on the timing of such liquidation as well as the amount of cash that will need to be reserved for
commitments and contingent liabilities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We may require substantial additional financial resources to continue as a going concern, including through the
strategic review process, and if we raise additional funds it may affect the value of your investment in our common stock.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our ability to consummate a strategic transaction depends on our ability to retain our current employees and
consultants.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our stock price has been, and may continue to be, volatile.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our decreasing cash reserves has resulted in our shareholder equity falling below $2,500,000 as required by
Nasdaq Listing Rule 5550(b)(1), which resulted in our receipt of a delisting notice from Nasdaq. in April of 2025. While we have reestablished compliance with the listing rule based on our Quarterly Report on Form 10-Q for the period ended
June 30, 2025, evidencing stockholders' equity of $3.66 million, we remain at risk of future non-compliance if our cash reserves continue to decline or if we face unexpected financial challenges, which could lead to further delisting
actions by Nasdaq.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We have identified a material weakness and failed to maintain an effective internal control environment, which
may result in material misstatements of our financial statements or have a material adverse effect on our business or stock price.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our small molecule obesity program is early stage and may encounter issues with manufacturing of the active
pharmaceutical ingredient(s) or with the in vitro or in vivo studies that could preclude clinical trials or be costly to address with respect to time or money.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• For our small molecule oral obesity program or should we resume development of our TCR-T product candidates, any candidate for which we obtain marketing approval could be subject to post-marketing restrictions or withdrawal from the market and we may be subject to significant penalties if we
fail to comply with regulatory requirements or if we experience unanticipated problems with our products, when and if any of them are approved.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• For our small molecule oral obesity program, or should we resume development of our TCR-T product candidates, if we fail to obtain the necessary U.S. or worldwide regulatory approvals to commercialize any product candidate, our business will suffer materially.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We may not be able to commercialize, generate significant revenues from, or attain profitability from our small
molecule oral obesity program or, should we resume development of, our TCR-T product candidates.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The termination of our TCR-T related licenses and research and
development agreements could limit our ability to resume our TCR-T clinical trial or begin new clinical trials.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We may become involved in litigation, including securities class action litigation, that could divert
management's attention and harm our business, and insurance coverage may not be sufficient to cover all costs and damages.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our product candidates may cause undesirable side effects or have other properties that could delay or prevent
their regulatory approval, limit the commercial profile of an approved label or result in significant negative consequences following any potential marketing approval.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The gene transfer vectors from the Sleeping Beauty system used to manufacture our TCR-T product candidates may incorrectly modify the genetic material of a patient's T cells, potentially triggering the development of a new cancer or other adverse events.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• If we are unable either to create sales, marketing and distribution capabilities or enter into agreements with
third parties to perform these functions, we will be unable to commercialize our product candidates successfully.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• If physicians and patients do not accept and use our product candidates, once approved, or if we do not obtain
coverage and adequate reimbursement from payors, our ability to generate revenue from sales of our products will be materially and adversely impaired.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our small molecule and immuno-oncology product candidates may face competition in the future from generics or
biosimilars and/or new technologies and our pending patent applications may not be granted, further limiting our ability to compete with other companies.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• If we fail to adequately protect or enforce our intellectual property rights or secure rights to patents of
others, the value of our intellectual property rights would diminish and our ability to successfully commercialize our products may be materially impaired.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Third-party claims of intellectual property infringement would require us to spend significant time and money and
could prevent us from developing or commercializing our products.

**The Mast Hill Transaction** 

On May 19, 2025, we entered into an equity purchase agreement (the "*Purchase Agreement*") and a registration rights agreement (the "*Registration Rights Agreement*") with Mast Hill Fund, L.P., a Delaware limited

------

partnership ("*Mast Hill*"). Pursuant to the Purchase Agreement, Mast Hill has committed to purchase up to $25,000,000 of the Company's newly issued shares common stock, par value $0.001 per share (the "*common stock*"), from time to time during the term of the Purchase Agreement, subject to certain limitations and conditions (the "*Mast Hill Offering*").

The Purchase Agreement initially precludes us from issuing and selling more than 327,740 shares of our common stock, including the Warrant Shares, which number equals 19.99% of our common stock issued and outstanding as of May 18, 2025, unless we obtain stockholder approval to issue additional shares, or unless certain exceptions apply. In addition, a beneficial ownership limitation in the agreement initially limits us from directing Mast Hill to purchase shares of common stock if such purchases would result in Mast Hill beneficially owning more than 4.99% of the then-outstanding shares of our common stock.

Upon the terms and subject to the satisfaction of the conditions set forth in the Purchase Agreement, the Company has the right, but not the obligation, to sell to Mast Hill, and Mast Hill is obligated to purchase, up to $25,000,000 of common stock, at a purchase price per share equal to the lesser of (i) 97% of the lowest VWAP of the Company's common stock, as listed on Nasdaq, on any trading day during the period beginning on the put date and continuing through the date that is two trading days immediately following the clearing date associated with the applicable put notice (such two trading day period is the "*Valuation Period*"), or (ii) 102% of the lowest traded price of the Company's common stock, as listed on Nasdaq, on any trading day during the Valuation Period, on such date on which the purchase price is calculated in accordance with the terms of the Purchase Agreement. Such sales of common stock by the Company, if any, are subject to certain limitations set forth in the Purchase Agreement, and may occur from time to time, at the Company's sole discretion, over a period of up to 24-months, commencing on the date of the Purchase Agreement, including the effectiveness of a registration statement registering under the Securities Act, the resale by Mast Hill of shares of common stock that may be issued by the Company to Mast Hill under the Purchase Agreement and upon the exercise of the Warrant (as defined below). The Company has agreed to file such registration statement with the Securities and Exchange Commission within 60 days from the date of execution of the Purchase Agreement and the Registration Rights Agreement. We will control the timing and amount of any such sales of common stock to Mast Hill. Actual sales of shares of common stock to Mast Hill 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 our common stock, and determinations by us as to the appropriate sources of funding for the Company and our operations.

We have the right to terminate the Purchase Agreement at any time after its commencement, at no cost or penalty, upon prior written notice to Mast Hill, except during any Valuation Period or at any time that Mast Hill holds any shares of common stock purchased by Mast Hill under the Purchase Agreement.

As consideration for Mast Hill's commitment to purchase shares of common stock in accordance with the Purchase Agreement, the Company has issued to Mast Hill a warrant to purchase 79,900 shares of common stock (as amended, the "*Warrant*") concurrently with the execution of the Purchase Agreement. The Warrant is immediately exercisable and will expire on the fifth anniversary of the original issuance date. The Warrant has an initial exercise price per share of $4.00. The exercise price and number of shares of common stock issuable upon exercise is subject to appropriate adjustment in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications or similar events affecting the common stock and anti-dilution adjustments. On June 9, 2025, the Company entered into an Amendment No. 1 to the common stock Purchase Warrant Issued on May 19, 2025 (the "*Warrant Amendment*") with Mast Hill. The Warrant Amendment (i) added a floor price equal to $0.57 per share, with respect to certain adjustment to the exercise price of the Warrant in the event of any Dilutive Issuance (as defined in the Warrant), issuance of Variable Price (as defined in the Warrant) securities and certain other events set forth in Section 2(e) of the Warrant; (ii) removed the requirement to adjust the number of shares of common stock issuable upon exercise of the Warrant in the event of a Dilutive Issuance, a Variable Price adjustment or under Section 2(e) of the Warrant; and (iii) removed certain rights of the Warrant holder in connection with fundamental transactions.

------

We intend to use the net proceeds, if any, from the Mast Hill Offering for working capital and general corporate purposes, including sales and marketing activities, product development and capital expenditures. We may also use a portion of the net proceeds to acquire or invest in complementary businesses, products and technologies. The Purchase Agreement and the Registration Rights Agreement contain customary representations, warranties, conditions and indemnification obligations of the parties.

**Series A-1 Preferred Stock** 

On April 11, 2025, the Company entered into a Subscription Agreement (the "*Series A-1 Subscription Agreement*"), by and among the Company and Water Mill Asset Management ("*Water Mill*"), pursuant to which the Company agreed to issue and sell, in a private offering to Water Mill, shares of the Series A-1 Convertible Preferred Stock, par value $0.001 per share, of the Company (the "*Series A-1 Preferred Stock*"), at a price per share of $1,000 (the "*Series A-1 Preferred Offering*") for an aggregate purchase price of $500,000. The Series A-1 Preferred Offering also relates to the offering of the shares of the common stock issuable upon the conversion of or otherwise pursuant to the terms of the Series A-1 Preferred Stock (such shares of common stock, the "*Series A-1 Conversion Shares*").

In any such vote, each holder of Series A-1 Preferred Stock shall be entitled to a number of votes equal to the number of shares of common stock into which such holder's shares of Series A-1 Preferred Stock are convertible pursuant to the Series A-1 Certificate of Designation as of the record date of such vote or written consent (or as otherwise required by applicable law).

Each holder of Series A-1 Preferred Stock has the right to convert all or any portion of the outstanding Series A-1 Preferred Stock held by such holder along with the aggregate accrued or accumulated and unpaid dividends thereon, at any time at such holder's option, into shares of common stock in accordance with the terms of the Series A-1 Certificate of Designation. The initial fixed conversion price shall be $2.76 per share for Series A-1 Preferred Stock, subject to proportional adjustments in accordance with the Series A-1 Certificate of Designation.

**Series A-2 Preferred Stock** 

On June 24, 2025, the Company entered into a Subscription Agreement (the "*Series A-2 Subscription Agreement*", and together with the Series A-2 Subscription Agreement, the "*Subscription Agreement*"), by and among the Company and subscribers set forth on Appendix A thereto (the "*Buyers*"), pursuant to which the Company agreed to issue and sell, in a private offering to the Buyers, shares of the Series A-2 Convertible Preferred Stock, par value $0.001 per share, of the Company (the "*Series A-2 Preferred Stock*"), at a price per share of $1,000 (the "*Series A-2 Preferred Offering*") for an aggregate purchase price of $850,000. The Series A-2 Preferred Offering also relates to the offering of the shares of the common stock issuable upon the conversion of or otherwise pursuant to the terms of the Series A-2 Preferred Stock (such shares of common stock, the "*Series A-2 Conversion Shares*"). The Series A-2 Preferred Offering closed on June 24, 2025.

------

Under the terms of the Certificate of Designation of Series A-2 Convertible Preferred Stock (the "*Series A-2 Certificate of Designation*") filed by the Company with the Secretary of State of the State of Delaware on June 24, 2025, each share of Series A-2 Preferred Stock has a stated value of $1,000 per share and, when issued, the Series A-2 Preferred Stock will be fully paid and non-assessable. The holders of Series A-2 Preferred Stock will be entitled to receive dividends at a rate of 10% per annum, payable in shares of Series A-2 Preferred Stock. In addition, the holders of Series A-2 Preferred Stock, to the extent any other dividends or distributions are declared for holders of the common stock, the holders of Series A-2 Preferred Stock will be entitled to participate in such dividends or distributions on an as-converted basis.

**RISK FACTORS** 

*Investing in our securities involves a high degree of risk. Before deciding whether to purchase any of our securities, you should carefully consider the risks and uncertainties described below, in the section titled* "*Risk Factors*" *in our Annual Report on Form 10-K for the year ended December 31, 2024 (the* "*2024 Annual Report*"*) in our Quarterly Reports on Form 10-Q for the fiscal quarters ended March 31, 2025 and June 30, 2025 (the "Quarterly Reports on Form 10-Q"), and in other documents that we subsequently file with the SEC that update, supersede or supplement such information, which are incorporated by reference into this prospectus, in any prospectus supplement to this prospectus and in any free writing prospectus that we have authorized for use in connection with this offering. If any of these risks actually occur, our business, financial condition and results of operations could be materially and adversely affected and we may not be able to achieve our goals, the value of our securities could decline and you could lose some or all of your investment. Additional risks not presently known to us or that we currently deem immaterial may also impair our business operations. If any of these risks occur, the trading price of our common stock could decline materially and you could lose all or part of your investment.*

**Risks Related to Our common stock and this Offering** 

***It is not possible to predict the actual number of shares we will sell under the Purchase Agreement to Mast Hill, or the actual gross proceeds resulting from those sales.***

On May 19, 2025, we entered into the Purchase Agreement with Mast Hill, pursuant to which Mast Hill committed to purchase up to $25,000,000 in shares of our common stock, subject to certain limitations and conditions set forth in the Purchase Agreement. We generally have the right to control the timing and amount of any sales of our shares of common stock to Mast Hill under the Purchase Agreement, although we are unable to control the market price of the common stock at the time such shares are sold or the purchase price per share that Mast Hill will pay for such shares. Our decision to sell shares of common stock under the Purchase Agreement, if any, to Mast Hill will depend upon market conditions, the trading price of the common stock, determinations by us as to the appropriate sources of funding for our operations, and other factors to be determined by us. We may ultimately decide to sell to Mast Hill all, some, or none of the Purchase Shares that may be available for us to sell pursuant to the Purchase Agreement.

Moreover, although the Purchase Agreement provides that we may sell up to an aggregate of $25,000,000 of Purchase Shares to Mast Hill, we are precluded from issuing and selling more than 327,740 shares of our common stock (including the Warrant Shares), which number equals 19.99% of the number of shares of our common stock issued and outstanding as of May 19, 2025 (the "*Exchange Cap*"), unless we obtain stockholder approval to issue shares of our common stock in excess of the Exchange Cap. If, after the Commencement Date (as defined below), we elect to sell to Mast Hill all of the Purchase Shares permitted under the Purchase Agreement, the actual gross proceeds from the sale of all such Mast Hill may be substantially less than the $25,000,000 total commitment in light of the Exchange Cap limitation, which could materially adversely affect our liquidity.

Further, because the purchase price per share to be paid by Mast Hill for the Purchase Shares that we may elect to sell to them under the Purchase Agreement, if any, will fluctuate based on the market prices of our common stock during the three consecutive trading day period immediately following the exercise date for such purchase made pursuant to the Purchase Agreement, it is not possible for us to predict, as of the date of this prospectus and prior to any such sales, the number of shares of common stock that we will sell to Mast Hill thereunder, if any, the purchase price per share that Mast Hill will pay for such shares, or the aggregate gross proceeds that we will receive from those purchases, if any.

------

***Management has broad discretion as to the use of proceeds from our sale of common stock under the Purchase Agreement, if any, and our sales of the Series A-1 Preferred Stock or the Series A-2 Preferred Stock pursuant to the Subscription Agreements, and may invest or spend the proceeds in ways with which you do not agree and in ways that may not increase the value of your investment.***

Our management has broad discretion over the use of proceeds from the sale of shares of common stock to Mast Hill pursuant to the Purchase Agreement, if any, or the sales of the Series A-1 Preferred Stock or the Series A-2 Preferred Stock pursuant to the Subscription Agreements. You may not agree with our decisions, and our use of the proceeds may not yield any return on your investment. Our failure to effectively apply the net proceeds from such sale could compromise our ability to pursue our business strategy, and we might not be able to yield a significant return, if any, on our investment of these net proceeds. In addition, the net proceeds from such sale may not be sufficient for our anticipated uses, and we may need additional resources to progress our service offerings to the stage we expect. You will not have the opportunity to influence our decisions on how to use our net proceeds from the sale of shares of common stock to Mast Hill pursuant to the Purchase Agreement, or the sales of the Series A-1 Preferred Stock or the Series A-2 Preferred Stock pursuant to the Subscription Agreements.

***The sale or issuance of the securities registered for resale hereunder, or the perception that such sales may occur, could cause the price of our common stock to decrease.***

The sale of shares of our common stock to Mast Hill as Purchase Shares under the Purchase Agreement will be at our sole discretion from time to time, commencing after the satisfaction of certain conditions set forth in the Purchase Agreement until May 19, 2027. The purchase price for the Purchase Shares that we may sell to Mast Hill under the Purchase Agreement will fluctuate based on the trading price of our common stock. Depending on market liquidity at the time, sales of such Purchase Shares may cause the trading price of our common stock to decrease. We generally have the right to control the timing and amount of any future sales of Purchase Shares to Mast Hill. We may ultimately decide to sell to Mast Hill all, some or none of the Purchase Shares that may be available for us to sell pursuant to the Purchase Agreement. If and when we do sell Purchase Shares to Mast Hill, after Mast Hill Mast Hill acquired the Purchase Shares, Mast Hill may resell all, some or none of those shares at any time or from time to time in its discretion. Therefore, sales to Mast Hill by us could result in substantial dilution to the interests of other holders of our common stock.

We are also registering for resale hereunder up to 217,390 Series A-1 Conversion Shares issuable upon the conversion of or otherwise pursuant to the terms of Series A-1 Preferred Stock and up to 227,170 Series A-2 Conversion Shares issuable upon the conversion of or otherwise pursuant to the terms of Series A-2 Preferred Stock. Accordingly, our existing stockholders may experience substantial dilution as a result of the sale of shares of common stock pursuant to this prospectus. The sale of these securities in the public market, or the perception that holders of a large number of securities intend to sell their securities, could reduce the market price of our common stock. However, the number of shares of our common stock ultimately offered for resale by the Buyers under this prospectus is dependent upon the number of shares of common stock ultimately issued to the Buyers.

We cannot predict if and when the Selling Securityholders may sell such shares of the common stock in the public markets.

In addition, the purchase price for the Purchase Shares under the Purchase Agreement, or the conversion price of Series A-1 Preferred Stock or Series A-2 Preferred Stock, may be below the current and/or then trading prices of shares of our common stock or below the price at which our existing shareholders purchased our common stock. The Selling Stockholders may potentially make a significant profit with the resale of the securities depending on the trading price of our securities at the time of a sale and the purchase price of such securities by them. While the Selling Stockholders may experience a positive rate of return based on the trading price of our securities, the existing holders of our common stock may not experience a similar rate of return on the shares of common stock they purchased due to differences in the applicable purchase price and trading price.

------

Additionally, the sale of a substantial number of shares of our common stock by the Selling Stockholders, or the anticipation of such sales, could 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 sales.

***The terms of the Purchase Agreement limit the amount of shares of common stock we may issue to Mast Hill, which may have an adverse effect on our liquidity.***

The Purchase Agreement includes restrictions on our ability to sell Purchase Shares to Mast Hill, including, subject to specified limitations, if a sale would cause Mast Hill and its affiliates to beneficially own more than 4.99% of our issued and outstanding common stock. Accordingly, we cannot guarantee that we will be able to sell all $25,000,000 shares of common stock under the Purchase Agreement. If we cannot sell the full amount of the shares that Mast Hill 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.

***We may issue additional equity or equity-linked securities in the future, which may result in additional dilution to you.***

We expect that significant additional capital will be needed in the future to continue our planned operations. To the extent that we raise additional capital by issuing equity securities, including securities exercisable for or convertible into shares of our common stock, our existing shareholders' ownership may experience substantial dilution, and the terms of these securities may include liquidation or other preferences that adversely affect your rights as a common shareholder.

***Although our common stock is listed on the Nasdaq Capital Market, our shares are likely to be thinly traded for some time and an active market may never develop.***

Although our common stock is listed on the Nasdaq Capital Market, it is likely that initially there will be a very limited trading market for our common stock, and we cannot ensure that a robust trading market will ever develop or be sustained. Our shares of common stock may be thinly traded, and the price, if traded, may not reflect our actual or perceived value. There can be no assurance that there will be an active market for our shares of common stock in the future. The market liquidity will be dependent on the perception of our operating business, competitive forces, state of the live stream and gaming industry, growth rate and becoming cash flow profitable on a sustainable basis, among other things. We may, in the future, take certain steps, including utilizing investor awareness campaigns, press releases, road shows, and conferences to increase awareness of our business and any steps that we might take to bring us to the awareness of investors may require we compensate financial public relations firms with cash and/or stock. There can be no assurance that there will be any awareness generated or the results of any efforts will result in any impact on our trading volume. Consequently, investors may not be able to liquidate their investment or liquidate it at a price that reflects the value of the business and trading may be at an inflated price relative to the performance of our company due to, among other things, availability of sellers of our shares. If a market should develop, the price may be highly volatile. Because there may be a low price for our shares of common stock, many brokerage firms or clearing firms may not be willing to effect transactions in the securities or accept our shares for deposit in an account. Even if an investor finds a broker willing to effect a transaction in the shares of our common stock, the combination of brokerage commissions, transfer fees, taxes, if any, and any other selling costs may exceed the selling price. Further, many lending institutions will not permit the use of low-priced shares of common stock as collateral for any loans.

***We received a notice from Nasdaq that our common stock may be delisted from trading on the Nasdaq Capital Market if we fail to comply with the continued listing requirements, including the minimum bid price requirement. A delisting of our common stock is likely to reduce the liquidity of our common stock and may inhibit or preclude our ability to raise additional financing.***

We are required to comply with certain Nasdaq continued listing requirements, including a minimum bid price for our common stock, as well as a series of financial tests relating to stockholder equity, market value of listed

------

securities and number of market makers and stockholders. If we fail to maintain compliance with any of those requirements, our common stock could be delisted from Nasdaq.

Our decreasing cash reserves has resulted in our shareholder equity falling below $2,500,000 as required by Nasdaq Listing Rule 5550(b)(1), which resulted in our receipt of a delisting notice from Nasdaq in April of 2025. In our 2024 Annual Report, we reported stockholders' equity of $2,063,000. While we have reestablished compliance with the listing rule based on our Quarterly Report on Form 10-Q for the period ended June 30, 2025, evidencing stockholders' equity of $3.66 million, we remain at risk of future non-compliance if our cash reserves continue to decline or if we face unexpected financial challenges, which could lead to further delisting actions by Nasdaq.

If our common stock is delisted by Nasdaq, it could lead to a number of negative implications, including an adverse effect on the price of our common stock, deterring broker-dealers from making a market in or otherwise seeking or generating interest in our common stock, increased volatility in our common stock, reduced liquidity in our common stock, the loss of federal preemption of state securities laws and greater difficulty in obtaining financing. Delisting could also cause a loss of confidence of our customers, collaborators, vendors, suppliers and employee, which could harm our business and future prospects.

If our common stock is delisted by Nasdaq, the price of our common stock may decline, and although our common stock may be eligible to trade on the OTC Bulletin Board, another over-the-counter quotation system, or on the pink sheets, an investor may find it more difficult to dispose of their common stock or obtain accurate quotations as to the market value of our common stock. If our common stock is delisted from Nasdaq, trading in our securities may be subject to the SEC's "penny stock" rules. These "penny stock" rules will require brokers trading in our common stock to adhere to more stringent rules and possibly result in a reduced level of trading activity in the secondary trading market for our common stock. The additional burdens imposed upon broker-dealers by these requirements may discourage broker-dealers from recommending transactions in our securities, which could severely limit the liquidity of our securities and consequently adversely affect the market price for our securities. Furthermore, if our common stock is delisted, we would expect it to have an adverse impact on our ability to consummate certain strategic alternatives.

Further, if our common stock is delisted, we would incur additional costs under state blue sky laws in connection with any sales of our securities. These requirements could severely limit the market liquidity of our common stock and the ability of our stockholders to sell our common stock in the secondary market.

**THE MAST HILL TRANSACTION** 

**Description of the Purchase Agreement** 

On May 19, 2025, we entered into the Purchase Agreement and the Registration Rights Agreement with Mast Hill pursuant to which we have the right, but not the obligation, to sell to Mast Hill up to $25,000,000 of shares of common stock (the "*Total Commitment*" and shares of common stock sold pursuant to the Purchase Agreement, the "*Purchase Shares*"), subject to certain limitations and conditions set forth therein.

This prospectus covers the resale by Mast Hill of up to $594,816 of our common stock, all of which are shares of common stock that we may sell to Mast Hill under the Purchase Agreement from time to time over the 24-month period from and after the date of the Purchase Agreement.

The following is a description of the material terms of the issuance and sale of securities pursuant to the Purchase Agreement. It does not purport to be complete. This summary is subject to and is qualified by reference to all the provisions of the Purchase Agreement, the Registration Rights Agreement and the Warrant, including the definitions of certain terms used therein. We urge you to read these documents because they, and not this description, define your rights as the investor thereunder. You may request copies of these agreements, and related ancillary documents, as set forth under the section titled "*Where You Can Find Additional Information*."

As consideration for Mast Hill's commitment to purchase shares of common stock in accordance with the Purchase Agreement, the Company has issued to Mast Hill the Warrant to purchase 79,900 shares of common stock concurrently with the execution of the Purchase Agreement. The Warrant is immediately exercisable and will expire on the fifth anniversary of the original issuance date. The Warrant has an initial exercise price per share of $4.00. The exercise price and number of shares of common stock issuable upon exercise is subject to appropriate adjustment in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications or similar events affecting the common stock and anti-dilution adjustments. We also agreed to reimburse Mast Hill for certain out-of-pocket expenses incurred in connection with the transactions contemplated under the Purchase Agreement (including its legal fees and expenses), in an aggregate amount of approximately $17,500.

On June 9, 2025, the Company entered into the Warrant Amendment with Mast Hill. The Warrant Amendment (i) added a floor price equal to $0.57 per share, with respect to certain adjustment to the exercise price of the Warrant in the event of any Dilutive Issuance (as defined in the Warrant), issuance of Variable Price (as defined in the Warrant) securities and certain other events set forth in Section 2(e) of the Warrant; (ii) removed the requirement to adjust the number of shares of common stock issuable upon exercise of the Warrant in the event of a Dilutive Issuance, a Variable Price adjustment or under Section 2(e) of the Warrant; and (iii) removed certain rights of the Warrant holder in connection with fundamental transactions.

**Purchase and Sale of Common Stock** 

Upon the initial satisfaction of the conditions to our right to commence sales of Purchase Shares to Mast Hill set forth in the Purchase Agreement (such event, the "*Commencement*"), we will have the right, but not the obligation, from time to time at our sole discretion over the 24-month period from and after the date of the Purchase Agreement (the "*Commencement Date*"), subject to earlier termination as set forth in the Purchase Agreement, to direct Mast Hill to make purchases of Purchase Shares, as further described in the Purchase Agreement (each, a "*Purchase*") by delivering a Put Notice (as such term is defined in the Purchase Agreement) on any trading day (the trading day during the Commitment Period that a Put Notice is deemed delivered is, the "*Put Date*"), so long as the lowest traded price of the common stock in the 10 trading days immediately preceding the Put Date exceeds $0.01 per share. Such sales of common stock by the Company, if any, are subject to certain limitations set forth in the Purchase Agreement, including the effectiveness of a registration statement registering under the Securities Act, the resale by Mast Hill of shares of common stock that may be issued by the

------

Company to Mast Hill under the Purchase Agreement and underlies upon the exercise of the Warrant. The Company has agreed to file such registration statement with the Securities and Exchange Commission within 60 days from the date of execution of the Purchase Agreement and the Registration Rights Agreement.

The purchase price of the Purchase Shares that we elect to sell to Mast Hill pursuant to a Purchase (the "*Purchase Price*") will be the lesser of (i) 97% of the lowest VWAP of the Company's common stock, as listed on Nasdaq, on any trading day during the Valuation Period (such price, the "*Market Price*"), or (ii) 102% of the lowest traded price of the Company's common stock, as listed on Nasdaq, on any trading day during the Valuation Period (such price, the "*Market Alternative Price*"), on such date on which the Purchase Price is calculated in accordance with the terms of the Purchase Agreement. The Company may at its option specify a minimum share price with respect to the common stock (the "*Minimum Price*") in such Put Notice. If a Minimum Price is specified by the Company in the Put Notice and the common stock trades at a price per share that is less than the Minimum Price during the respective Valuation Period (the "*Minimum Price Trigger*"), then the number of Purchase Shares with respect to such Purchase shall automatically be reduced to the number of Purchase Sharees sold by Mast Hill prior to the first time that the common stock traded below the Minimum Price during the respective Valuation Period.

The Company may direct Mast Hill, by its delivery of a Put Notice, to purchase Purchase Shares: (i) in a minimum amount not less than $5,000 (calculated using 97% of the VWAP of the common stock, as reported on Nasdaq, on the trading date immediately preceding the applicable Put Date (the "*Initial Purchase Price*")) and (ii) in a maximum amount up to the lesser of (a) $500,000 (calculated using the Initial Purchase Price) or (b) 20% of the average trading volume of the common stock, as reported on Nasdaq, during the five trading days immediately preceding the applicable Put Date *multiplied* by the VWAP of the common stock as reported on Nasdaq on the trading date immediately preceding the applicable Put Date.

From and after Commencement, we will control the timing and amount of any sales of Purchase Shares to Mast Hill. Actual sales of Purchase Shares to Mast Hill under the Purchase Agreement will depend on a variety of factors to be determined by us from time to time, including, market conditions, the trading price of the common stock, and determinations by us as to the appropriate sources of funding for our operations. We may ultimately decide to sell to Mast Hill all, some, or none of the Purchase Shares that may be available for us to sell pursuant to the Purchase Agreement.

**Beneficial Ownership Limitation** 

The Purchase Agreement prohibits us from directing Mast Hill to purchase any Purchase Shares if those shares, when aggregated with all other shares of our common stock then beneficially owned by Mast Hill (as calculated pursuant to Section 13(d) of the Exchange Act, and Rule 13d-3 thereunder) would result in Mast Hill beneficially owning more than 4.99% of our issued and outstanding common stock (the "*Beneficial Ownership Limitation*").

**Exchange Cap** 

Under applicable Nasdaq rules, in no event may we issue to Mast Hill under the Purchase Agreement more than 327,740 shares of our common stock (including the Warrant Shares), which number of shares equals the Exchange Cap, unless we obtain stockholder approval to issue shares of common stock in excess of the Exchange Cap.

**Proceeds** 

Because the purchase price per share to be paid by Mast Hill for the Purchase Shares that we may elect to sell under the Purchase Agreement, if any, will fluctuate based on the market prices of our common stock during the Valuation Period for each Purchase made, as of the date of this prospectus it is not possible for us to predict the number of shares of common stock that we will sell to Mast Hill thereunder, the actual purchase price per share to be paid by Mast Hill for such shares, or the actual gross proceeds to be raised by us from those sales, if any.

------

As of August 20, 2025, there were 2,205,716 shares of our common stock issued and outstanding, which excludes both the Warrant Shares issuable to Mast Hill and the Purchase Shares we may, in our sole discretion, sell to Mast Hill from time to time from and after the date of the Purchase Agreement pursuant to the Purchase Agreement. Further, although the Purchase Agreement provides that we may issue and sell up to an aggregate of $25,000,000 of Purchase Shares to Mast Hill, only 327,740 shares of our common stock (representing the maximum number of shares we may issue and sell under the Purchase Agreement in light of the Exchange Cap limitation) may be sold to Mast Hill and are being registered for resale under this prospectus, which includes the Warrant Shares. If all of the shares offered hereunder were issued and outstanding as of August 20, 2025, such shares would represent approximately 12.99% of the total number of shares of our common stock outstanding as of August 20, 2025.

If, after the Commencement Date, we elect to sell to Mast Hill all of the Purchase Shares (in addition to the Warrant Shares) that are available for sale by us to Mast Hill under the Purchase Agreement and that are being registered for resale under this prospectus, depending on the market prices of our common stock during the applicable Valuation Period for each Purchase made pursuant to the Purchase Agreement, the actual gross proceeds to us from the sale of all such shares may be substantially less than the $25,000,000 Total Commitment.

If it becomes necessary for us to issue and sell to Mast Hill more shares of our common stock than are being registered for resale under this prospectus, we must first (i) obtain stockholder approval to issue shares of our common stock in excess of the Exchange Cap in accordance with applicable Nasdaq rules, and (ii) file with the SEC one or more additional registration statements to register under the Securities Act the resale by Mast Hill of any such additional shares of our common stock we wish to sell from time to time under the Purchase Agreement, which the SEC must declare effective, in each case before we may elect to sell any additional shares of our common stock to Mast Hill under the Purchase Agreement. Any issuance and sale by us under the Purchase Agreement of a substantial amount of shares of our common stock in addition to the 327,740 shares being registered for resale hereunder could cause additional substantial dilution to our stockholders. The number of shares of our common stock ultimately offered for sale by Mast Hill is dependent upon the number of Purchase Shares, if any, we ultimately sell to Mast Hill under the Purchase Agreement.

The proceeds from sales of Purchase Shares, if any, under the Purchase Agreement will depend on the frequency and prices at which we sell Purchase Shares to Mast Hill. To the extent we sell Purchase Shares under the Purchase Agreement, we plan to use any proceeds therefrom for working capital and general corporate purposes, including sales and marketing activities, product development and capital expenditures.

**Conditions Precedent to Commencement and For Delivery of Purchase Notices** 

Our right to deliver Purchase Notices to Mast Hill under the Purchase Agreement, and Mast Hill's obligation to accept Put Notices delivered by us, are subject to (i) the initial satisfaction, at the Commencement, and (ii) the satisfaction, on the applicable Put Date for each Purchase after the Commencement Date, of the conditions precedent thereto set forth in the Purchase Agreement, which conditions include the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• since the date of filing of the Company's most recent filing required under the Securities Act and the
Exchange Act, no event that had or is reasonably likely to have a material adverse effect has occurred;

aggregated with all other shares of common stock then owned by Mast Hill beneficially or deemed beneficially owned by Mast Hill, shall not exceed the Beneficial Ownership Limitation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the Company shall have no knowledge of any event more likely than not to have the effect of causing the
registration statement that includes this prospectus (or any one or more additional registration statements filed with the SEC that include shares of common stock that may be issued and sold by us to Mast Hill under the Purchase Agreement and upon
exercise of the Warrant) to be suspended or otherwise ineffective;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the issuance of the Purchase Shares shall not violate the shareholder approval requirements of Nasdaq;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• on the date of delivery of each Put Notice, Mast Hill shall have received the closing certificate executed by an

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the common stock must be DWAC eligible and not subject to a "DTC chill";

------

**Covenants** 

The Purchase Agreement contains customary representations, warranties, covenants and indemnification obligations of the parties. The representations, warranties and covenants contained in the Purchase Agreement were made only for purposes of such agreement and as of specific dates, were solely for the benefit of the parties to such agreement, and may be subject to limitations agreed upon by the contracting parties.

**Restrictions** 

There are no restrictions on future financings, rights of first refusal, participation rights, penalties or liquidated damages in the Purchase Agreement, other than a prohibition on entering into certain "Equity Line of Credit" or "Variable Rate Transactions," as defined in the Purchase Agreement. Mast Hill has agreed not to cause, or engage in any manner whatsoever in, any direct or indirect short selling of our common stock during the term of the Purchase Agreement.

**Termination** 

The Purchase Agreement will automatically terminate upon the earliest of (i) the expiration of the 24-month period following the Commencement Date, (ii) Mast Hill's purchase of the Purchase Shares equal to Total Commitment, or (iii) the occurrence of certain other events set forth in the Purchase Agreement.

We have the right to terminate the Purchase Agreement at any time after Commencement, at no cost or penalty, upon prior written notice to Mast Hill, provided that Mast Hill no longer holds any Purchase Shares and such notice is not delivered during a Valuation Period.

**Existing Stockholders; Dilution** 

All shares of common stock registered in this offering which have been or may be issued or sold by us to Mast Hill under the Purchase Agreement are expected to be freely tradable. It is anticipated that shares of common stock registered in this offering may be issued and sold by us to Mast Hill from time to time at our discretion over a period of up to 24 months commencing on the Commencement Date. The issuance of shares of our common stock to Mast Hill pursuant to the Purchase Agreement will not affect the rights or privileges of our existing common stockholders, except that the economic and voting interests of each of our existing common stockholders will be diluted. 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 common stock after any such issuance. There are substantial risks to our stockholders as a result of the sale and issuance of common stock to Mast Hill under the Purchase Agreement. For additional information, refer to the sections of this prospectus titled "*Risk Factors*" and "*Dilution*."

**Effect of Performance of the Purchase Agreement on Our Stockholders** 

All 327,740 shares of common stock registered in this offering which have been or may be issued or sold by us to Mast Hill under the Purchase Agreement are expected to be freely tradable. It is anticipated that Common Shares registered in this offering will be sold over a period starting on the date that the registration statement of which this prospectus is a part is declared effective and ending on the first day of the month immediately following the 24 month anniversary of the execution date of the Purchase Agreement.

The sale by Mast Hill of a significant amount of Common Shares registered in this offering at any given time could cause the market price of Common Shares to decline and to be highly volatile. Sales of common stock to Mast Hill, if any, will depend upon market conditions and other factors to be determined by us. We may ultimately decide to sell to Mast Hill all, some or none of the additional Common Shares that may be available for us to sell pursuant to the Purchase Agreement.

------

If and when we do sell shares to Mast Hill, after Mast Hill has acquired the Common Shares, Mast Hill may resell all, some or none of those Common Shares at any time or from time to time in its discretion. Therefore, sales to Mast Hill by us under the Purchase Agreement may result in substantial dilution to the interests of other holders of Common Shares. In addition, if we sell a substantial number of Common Shares to Mast Hill under the Purchase Agreement, or if investors expect that we will do so, the actual sales of Common Shares or the mere existence of our arrangement with Mast Hill 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 Common Shares to Mast Hill and the Purchase Agreement may be terminated by us at any time at our discretion without any cost to us.

**Preferred Stock** 

Pursuant to our certificate of incorporation, our Board has the authority, without stockholder approval, subject to limitations prescribed by law, to provide for the issuance of up to 30,000,000 shares of preferred stock in one or more series, and by filing a certificate pursuant to the applicable law of the State of Delaware, to establish from time to time the number of shares to be included in each such series, and to fix the designation, powers, preferences and rights of the shares of each series and any qualifications, limitations or restrictions thereof, and to increase or decrease the number of shares of any such series, but not below the number of shares of such series then outstanding. We have designated 250,000 shares of our preferred stock as our Series 1 Preferred Stock, none of which are outstanding, 1,000 shares of our preferred stock as our Series A-1 Preferred Stock, 500 shares of which are outstanding, and 1,000 shares of our preferred stock as our Series A-2 Preferred Stock, 850 shares of which are outstanding.

We will fix the designations, voting powers, preferences and rights of the preferred stock of each series, as well as the qualifications, limitations or restrictions thereof, in the certificate of designation relating to that series. We will file as an exhibit to the registration statement of which this prospectus is a part, or will incorporate by reference from reports that we file with the SEC, the form of any certificate of designation that describes the terms of the series of preferred stock we are offering before the issuance of that series of preferred stock. This description will include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the title and stated value;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the number of shares offered;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the liquidation preference per share;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the purchase price per share;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the dividend rate(s), period(s) and/or payment date(s) or method(s) of calculation for dividends;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• whether dividends are cumulative or non-cumulative and, if
cumulative, the date from which dividends will accumulate;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our right, if any, to defer payment of dividends and the maximum length of any such deferral period;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the procedures for any auction and remarketing, if any;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the provisions for a sinking fund, if any;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the provision for redemption or repurchase, if applicable, and any restrictions on our ability to exercise those
redemption and repurchase rights;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any listing of the preferred stock on any securities exchange or market;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the terms and conditions, if applicable, upon which the preferred stock will be convertible into common stock,
including the conversion price (or manner of calculation) and conversion period;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• whether the preferred stock will be exchangeable into debt securities, and, if applicable, the exchange price, or
how it will be calculated, and the exchange period;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• voting rights, if any, of the preferred stock;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• preemptive rights, if any;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• restrictions on transfer, sale or other assignment, if any;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• whether interests in the preferred stock will be represented by depositary shares;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the relative ranking and preferences of the preferred stock as to dividend rights and rights upon the
liquidation, dissolution or winding up of our affairs;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any limitations on issuance of any class or series of preferred stock ranking senior to or on a parity with the
class or series of preferred stock as to dividend rights and rights upon liquidation, dissolution or winding up of our affairs; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any other specific terms, preferences, rights, limitations or restrictions of the preferred stock.

Our Board could authorize the issuance of shares of preferred stock with terms and conditions that could have the effect of discouraging a takeover or other transaction that might involve a premium price for holders of the shares or which holders might believe to be in their best interests. The issuance of preferred stock could adversely affect the voting power, conversion or other rights of holders of common stock and reduce the likelihood that common stockholders will receive dividend payments and payments upon liquidation.

The laws of the state of Delaware, the state of our incorporation, provide that the holders of preferred stock will have the right to vote separately as a class on any proposal involving fundamental changes in the rights of holders of such preferred stock. This right is in addition to any voting rights that may be provided for in the applicable certificate of designation.

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

The Preferred Offering also relates to the offering of the Series A-1 Conversion Shares issuable upon the conversion of or otherwise pursuant to the terms of the Series A-1 Preferred Stock. The Series A-1 Preferred Offering closed on April 11, 2025.

The holders of the Series A-1 Preferred Stock will have no preemptive or preferential rights to purchase or subscribe for any class of our stock, obligations, warrants or other securities.

Holders of shares of issued and outstanding Series A-1 Preferred Stock are entitled to receive, whether or not declared by our Board and whether or not there are funds legally available for the payment of dividends, cumulative dividends accrued on a daily basis in arrears at the rate of 10% per annum per share on the sum of the Series A-1 Stated Value (as defined below) thereof plus all unpaid accrued and accumulated dividends thereon; provided, that to the extent not paid on the last day of March, June, September, and December of each calendar year (each, a "*Series A-1 Dividend Payment Date*"), all accrued dividends on any share of Series A-1 Preferred Stock shall accumulate and compound on the applicable Series A-1 Dividend Payment Date whether or not declared by the Board and shall remain accumulated, compounding dividends until paid pursuant thereto or conversion of the Series A-1 Preferred Stock. The initial stated value per share (the "*Series A-1 Stated Value*") shall be $1,000, subject to appropriate adjustment in the event of stock splits, stock dividends, recapitalizations, or similar transaction with respect to the Series A-1 Preferred Stock. Dividends will be payable in kind through the issuance of additional shares of Series A-1 Preferred Stock.

In addition, the holders of Series A-1 Preferred Stock, to the extent any other dividends or distributions are declared for holders of the common stock, the holders of Series A-1 Preferred Stock will be entitled to participate

------

in such dividends or distributions on an as-converted basis, subject to certain limitations set forth in the Series A-1 Certificate of Designation.

***Liquidation***

Upon any liquidation, dissolution or winding-up of the Company, whether voluntary or involuntary, or certain deemed liquidation events, the holders of the Series A-1 Preferred Stock will be entitled to receive out of our assets, an amount equal to the aggregate Series A-1 Stated Value of all shares of Series A-1 Preferred Stock held by such holder, plus all unpaid accrued and accumulated dividends on all such shares of Series A-1 Preferred Stock (whether or not declared), before any distribution or payment shall be made to the holders of the common stock and any other class of securities that is specifically designated as junior to the Series A-1 Preferred Stock, and if the our assets shall be insufficient to pay in full such amounts, then the entire assets to be distributed to the holders of Series A-1 Preferred Stock shall be ratably distributed among the holders in accordance with the respective amounts that would be payable on such shares if all amounts payable thereon were paid in full.

***Voting Rights***

The holders of Series A-1 Preferred Stock are entitled to vote alongside holders of common stock on an as-converted basis on a 1:1 ratio as common stock, voting together as a single class, with respect to any and all matters presented to the stockholders of the Company for their action; provided, however, that, except as otherwise required by law, holders of common stock, as such, shall not be entitled to vote on any amendment to the Series A-1 Certificate of Designation. In any such vote, each holder of Series A-1 Preferred Stock shall be entitled to a number of votes equal to the number of shares of common stock into which such holder's shares of Series A-1 Preferred Stock are convertible pursuant to the Series A-1 Certificate of Designation as of the record date of such vote or written consent (or as otherwise required by applicable law).

***Conversions***

Subject to the provisions of the Series A-1 Certificate of Designation, the holder of Series A-1 Preferred Stock may, at its option, at any time and from time to time, convert all or any portion of outstanding shares of Series A-1 Preferred Stock then held by such holder, along with the aggregate accrued or accumulated and unpaid dividends thereon, into shares of common stock. Each share of Series A-1 Preferred Stock is convertible into such number of shares of common stock equal to (i) the sum of the Series A-1 Stated Value plus all accrued and accumulated and unpaid dividends thereon, divided by (ii) the conversion price in effect immediately prior to such conversion. The initial conversion price per share of Series A-1 Preferred Stock shall be $2.76. The conversion price is subject to adjustment in the event of (a) payment of dividend or other distribution upon the common stock or any other capital stock of the Company payable in shares of common stock or in options or convertible securities of the Company, (b) subdivision or combination of the Company's outstanding shares of common stock, or (c) reorganization, reclassification, consolidation, or merger involving the Company.

In addition, each share of Series A-1 Preferred Stock shall automatically convert into fully paid and nonassessable shares of the common stock, at the conversion price, without any action required by the holder of the Series A-1 Preferred Stock, upon the occurrence of a Change of Control (as defined in the Series A-1 Certificate of Designation).

***Limitations on Conversion***

No party may convert any shares of Series A-1 Preferred Stock or otherwise issue shares on account of such shares of Series A-1 Preferred Stock if, as a result of the conversion or issuance, a holder and its affiliates would beneficially own in excess of 4.99% of the shares of our common stock. However, upon 61 days' advance notice to us, a holder may increase the limit of beneficially owned shares of our common stock from 4.99% to any amount up 9.99% of the shares of our common stock. In the event that the issuance of shares of Common Stock to a holder upon conversion of, or otherwise on account, the shares of Series A-1 Preferred Stock results in such

------

holder and its affiliates being deemed to beneficially own, in the aggregate, more than the maximum percentage described in the preceding sentence of the number of outstanding shares of our Common Stock (as determined under Section 13(d) of the Exchange Act), the number of shares so issued by which the holder's and its affiliates' aggregate beneficial ownership exceeds such maximum percentage will be deemed null and void and will be cancelled ab initio, and the holder will not have the power to vote or to transfer such excess shares.

***Exchange Listing***

There is no established public trading market for the Series A-1 Preferred Stock, and we do not expect a market to develop. In addition, we do not intend to list the Series A-1 Preferred Stock on any securities exchange or nationally recognized trading system. Without an active trading market, the liquidity of the Series A-1 Preferred Stock will be limited.

**DESCRIPTION OF DEBT SECURITIES** 

We may issue debt securities from time to time, in one or more series, as either senior or subordinated debt or as senior or subordinated convertible debt. While the terms we have summarized below will apply generally to any debt securities that we may offer under this prospectus, we will describe the particular terms of any debt securities that we may offer in more detail in the applicable prospectus supplement. The terms of any debt securities offered under a prospectus supplement may differ from the terms described below. Unless the context requires otherwise, whenever we refer to the indenture, we also are referring to any supplemental indentures that specify the terms of a particular series of debt securities.

We will issue the debt securities under the indenture that we will enter into with the trustee named in the indenture. The indenture will be qualified under the Trust Indenture Act of 1939, as amended, or the Trust Indenture Act. Supplemental indentures and forms of debt securities containing the terms of the debt securities being offered will be filed as exhibits to the registration statement of which this prospectus is a part or will be incorporated by reference from reports that we file with the SEC.

The following summary of material provisions of the debt securities and the indenture is subject to, and qualified in its entirety by reference to, all of the provisions of the indenture applicable to a particular series of debt securities. We urge you to read the applicable prospectus supplements and any related free writing prospectuses related to the debt securities that we may offer under this prospectus, as well as the complete indenture that contains the terms of the debt securities.

**General** 

The indenture does not limit the amount of debt securities that we may issue. It provides that we may issue debt securities up to the principal amount that we may authorize and may be in any currency or currency unit that we may designate. Except for the limitations on consolidation, merger and sale of all or substantially all of our assets contained in the indenture, the terms of the indenture do not contain any negative covenants or other provisions designed to give holders of any debt securities protection against changes in our operations, financial condition or transactions involving us.

We may issue the debt securities issued under the indenture as "discount securities," which means they may be sold at a discount below their stated principal amount. These debt securities, as well as other debt securities that are not issued at a discount, may be issued with "original issue discount," or OID, for U.S. federal income tax purposes because of interest payment and other characteristics or terms of the debt securities. Material U.S. federal income tax considerations applicable to debt securities issued with OID will be described in more detail in any applicable prospectus supplement.

We will describe in the applicable prospectus supplement the terms of the series of debt securities being offered, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the title of the series of debt securities;

securities that is convertible into another security or the method by which any such portion shall be determined;

securities; the terms and conditions, if any, upon which such global security or securities may be exchanged in whole or in part for other individual securities; and the depositary for such global security or securities;

**Conversion or Exchange Rights** 

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

**Consolidation, Merger or Sale** 

Unless we provide otherwise in the prospectus supplement applicable to a particular series of debt securities, the indenture will not contain any covenant that restricts our ability to merge or consolidate, or sell, convey, transfer or otherwise dispose of our assets as an entirety or substantially as an entirety. However, upon any such consolidation or merger (in each case, if Alaunos is not the survivor of such transaction) or any such sale, conveyance, transfer or other disposition (other than a subsidiary of ours) the successor or acquiror must assume all of our obligations under the indenture or the debt securities, as appropriate.

**Events of Default under the Indenture** 

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if we fail to pay any installment of interest on any series of debt securities, as and when the same shall become
due and payable, and such default continues for a period of 90 days; provided, however, that a valid extension of an interest payment period by us in accordance with the terms of any indenture supplemental thereto shall not constitute a default in
the payment of interest for this purpose;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if we fail to pay the principal of, or premium, if any, on any series of debt securities as and when the same
shall become due and payable whether at maturity, upon redemption, by declaration or otherwise, or in any payment required by any sinking or analogous fund established with respect to such series; provided, however, that a valid extension of the
maturity of such debt securities in accordance with the terms of any indenture supplemental thereto shall not constitute a default in the payment of principal or premium, if any;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if we fail to observe or perform any other covenant or agreement contained in the debt securities or the
indenture, other than a covenant specifically relating to another series of debt securities, and our failure continues for 90 days after we receive written notice of such failure, requiring the same to be remedied and stating that such is a notice
of default thereunder, from the trustee or holders of at least 25% in aggregate principal amount of the outstanding debt securities of the applicable series; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if specified events of bankruptcy, insolvency or reorganization occur.

If an event of default with respect to debt securities of any series occurs and is continuing, other than an event of default specified in the last bullet point above, the trustee or the holders of at least 25% in aggregate principal

------

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

The holders of a majority in principal amount of the outstanding debt securities of an affected series may waive any default or event of default with respect to the series and its consequences if we have paid or deposited with the trustee a sum sufficient to pay all matured installments of principal and interest upon all the debt securities of that series that shall have become due otherwise than by acceleration, except defaults or events of default regarding payment of principal, premium, if any, or interest, unless we have cured the default or event of default in accordance with the indenture. Any waiver shall cure the default or event of default.

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

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

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

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series have
made written request,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• such holders have offered to the trustee indemnity satisfactory to it against the costs, expenses and liabilities
to be incurred by the trustee in compliance with the request; and

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

These limitations do not apply to a suit instituted by a holder of debt securities if we default in the payment of the principal, premium, if any, or interest on, the debt securities.

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

**Modification of Indenture; Waiver** 

We and the trustee may change an indenture without the consent of any holders with respect to specific matters:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to cure any ambiguity, defect or inconsistency in the indenture or in the debt securities of any series;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to comply with the provisions described above under "*Description of Debt Securities — Consolidation, Merger or Sale*;"

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to provide for uncertificated debt securities in addition to or in place of certificated debt securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to add to our covenants, restrictions, conditions or provisions such new covenants, restrictions, conditions or
provisions for the benefit of the holders of all or any series of debt securities, to make the occurrence, or the occurrence and the continuance, of a default in any such additional covenants, restrictions, conditions or provisions an event of
default or to surrender any right or power conferred upon us in the indenture;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to make any change that does not adversely affect the interests of any holder of debt securities of any series in
any material respect;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to evidence and provide for the acceptance of appointment under any indenture by a successor trustee; or

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• extending the fixed maturity of any debt securities of any series;

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

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

**Discharge** 

The indenture provides that we can elect to be discharged from our obligations with respect to one or more series of debt securities, except for specified obligations, including obligations to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• provide for payment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• register the transfer or exchange of debt securities of the series;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• pay principal of and premium and interest on any debt securities of the series;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• maintain paying agent agreements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• recover excess money held by the trustee;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• compensate and indemnify the trustee; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• appoint any successor trustee.

------

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

**Form, Exchange and Transfer** 

We will issue the debt securities of each series only in fully registered form without coupons and, unless we provide otherwise in the applicable prospectus supplement, in denominations of $1,000 and any integral multiple thereof. The indenture provides that we may issue debt securities of a series in temporary or permanent global form and as book-entry securities that will be deposited with, or on behalf of, The Depository Trust Company, or DTC, or another depositary named by us and identified in the applicable prospectus supplement with respect to that series. To the extent the debt securities of a series are issued in global form and as book-entry, a description of terms relating to any book-entry securities will be set forth in the applicable prospectus supplement.

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

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

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

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

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

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

**Information Concerning the Trustee** 

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

------

**Payment and Paying Agents** 

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

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

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

**Governing Law** 

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

**DESCRIPTION OF WARRANTS** 

The following description, together with the additional information we may include in any applicable prospectus supplement and in any related free writing prospectus that we may authorize to be distributed to you, summarizes the material terms and provisions of the warrants that we may offer under this prospectus, which may consist of warrants to purchase common stock, preferred stock or debt securities and be issued in one or more series. Warrants may be offered independently or in combination with common stock, preferred stock or debt securities offered by any prospectus supplement. While the terms we have summarized below will apply generally to any warrants that we may offer under this prospectus, we will describe the particular terms of any series of warrants in more detail in the applicable prospectus supplement. The following description of warrants will apply to the warrants offered by this prospectus unless we provide otherwise in the applicable prospectus supplement. The applicable prospectus supplement for a particular series of warrants may specify different or additional terms.

We will file as exhibits to the registration statement of which this prospectus is a part, or will incorporate by reference from reports that we file with the SEC, the form of warrant and/or the warrant agreement and warrant certificate, as applicable, that describe the terms of the particular series of warrants we are offering, and any supplemental agreements, before the issuance of such warrants. The following summaries of material terms and provisions of the warrants are subject to, and qualified in their entirety by reference to, all the provisions of the form of warrant and/or the warrant agreement and warrant certificate, as applicable, and any supplemental agreements applicable to a particular series of warrants that we may offer under this prospectus. We urge you to read the applicable prospectus supplement related to the particular series of warrants that we may offer under this prospectus, as well as any related free writing prospectuses, and the complete form of warrant and/or the warrant agreement and warrant certificate, as applicable, and any supplemental agreements, that contain the terms of the warrants.

**General** 

We will describe in the applicable prospectus supplement the terms of the series of warrants being offered, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the offering price and aggregate number of warrants offered;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the currency for which the warrants may be purchased;

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

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

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the terms of any rights to redeem or call the warrants;

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

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

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

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a discussion of any material or special U.S. federal income tax considerations of holding or exercising the
warrants;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the terms of the securities issuable upon exercise of the warrants; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any other specific terms, preferences, rights or limitations of or restrictions on the warrants.

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

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

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

**Exercise of Warrants** 

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

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

**Governing Law** 

Unless we otherwise specify in the applicable prospectus supplement, the warrants and any warrant agreements will be governed by and construed in accordance with the laws of the State of New York.

**Enforceability of Rights by Holders of Warrants** 

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

**CERTAIN PROVISIONS OF DELAWARE LAW,** 

**THE CERTIFICATE OF INCORPORATION AND BYLAWS** 

**Limitations on Directors' Liability** 

Our certificate of incorporation and our bylaws contain provisions indemnifying our directors and officers to the fullest extent permitted by law. In addition, as permitted by Delaware law, our certificate of incorporation provides that no director will be liable to us or our stockholders for monetary damages for breach of certain fiduciary duties as a director. The effect of this provision is to restrict our rights and the rights of our stockholders in derivative suits to recover monetary damages against a director for breach of certain fiduciary duties as a director, except that a director will be personally liable for:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the benefits to be derived from relationships with our collaborators;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any breach of his or her duty of loyalty to the registrant or its stockholders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• acts or omissions not in good faith which involve intentional misconduct or a knowing violation of law;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the payment of dividends or the redemption or purchase of stock in violation of Delaware law; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any transaction from which the director derived an improper personal benefit.

This provision does not affect a director's liability under the federal securities laws.

To the extent that our directors, officers and controlling persons are indemnified under the provisions contained in our certificate of incorporation, Delaware law or contractual arrangements against liabilities arising under the Securities Act, we have been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act, and is therefore unenforceable.

**Provisions that May Have an Anti-Takeover Effect** 

Certain provisions set forth in our certificate of incorporation, bylaws and in Delaware law, which are summarized below, are intended to enhance the likelihood of continuity and stability in the composition of our board of directors and in the policies formulated by our board of directors and to discourage certain types of transactions that may involve an actual or threatened change of control. In that regard, these provisions are designed to reduce our vulnerability to an unsolicited acquisition proposal. The provisions also are intended to discourage certain tactics that may be used in proxy fights. However, such provisions could have the effect of discouraging others from making tender offers for shares of our common stock and, as a consequence, they also may inhibit fluctuations in the market price of our common stock that could result from actual or rumored takeover attempts. Such provisions also may have the effect of preventing changes in our management.

*Blank Check Preferred Stock.* Our certificate of incorporation contains provisions that permit our board of directors to issue, without any further vote or action by the stockholders, up to 30,000,000 shares of preferred stock in one or more series and, with respect to each such series, to fix the number of shares constituting the series and the designation of the series, the voting powers (if any) of the shares of the series, and the preferences and relative, participating, optional and other special rights, if any, and any qualifications, limitations or restrictions, of the shares of such series. As a result, our board of directors could authorize the issuance of shares of preferred stock with terms and conditions that could have the effect of delaying, deferring or preventing a transaction or a change in control that might involve a premium price for holders of our common stock or otherwise be in their best interest.

*Special Meetings of Stockholders.* Our bylaws provide that special meetings of stockholders may be called only by the board of directors. Stockholders are not permitted to call a special meeting of stockholders or to require that the board of directors call such a special meeting.

------

*Delaware Takeover Statute.* 

We are subject to Section 203 of the Delaware General Corporation Law, or DGCL, which regulates acquisitions of some Delaware corporations. In general, Section 203 prohibits, with some exceptions, a Delaware corporation that is a public company from engaging in any "business combination" with any "interested stockholder" for a period of three years following the date that such stockholder became an interested stockholder, unless:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• prior to such 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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• on 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 outstanding those shares owned (x) by persons who are
directors and also officers and (y) by employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• on or subsequent to such date, the business combination is approved by the board of directors 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 of the DGCL defines "business combination" to include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any merger or consolidation involving the corporation and the interested stockholder;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any sale, transfer, pledge or other disposition of 10% or more of the assets of the corporation involving the
interested stockholder;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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 shareholder" as an entity or person beneficially owning 15% or more of the outstanding voting stock of the corporation and any entity or person affiliated with such entity or person.

**SELLING STOCKHOLDERS** 

This prospectus relates to the possible resale from time to time (i) by Mast Hill of any or all of the shares of our common stock that have been or may be issued or sold by us to Mast Hill under the Purchase Agreement and an additional 79,900 shares of our common stock, upon the exercise of the Warrant, (ii) by Water Mill of up to 217,390 shares of our common stock issuable upon conversion of or otherwise pursuant to the terms of our Series A-1 Preferred Stock, and (ii) by the Buyers of up to 227,170 shares of our common stock issuable upon conversion of or otherwise pursuant to the terms of our Series A-2 Preferred Stock. All such shares of common stock that are being registered under the Securities Act for resale by the Selling Stockholders in this offering are expected to be freely tradable. The resale by the Selling Stockholders of a significant number of shares of our common stock that are registered for resale 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. We are filing the registration statement of which this prospectus forms a part to satisfy the registration rights granted to Mast Hill pursuant to the provisions of the Registration Rights Agreement, and to Water Mill and the Buyers pursuant to the provisions of the Subscription Agreements.

**Mast Hill** 

Sales of Purchase Shares, if any, to Mast Hill under the Purchase Agreement will depend upon market conditions, the trading price of the common stock, determinations by us as to the appropriate sources of funding for our operations, and other factors to be determined by us. We may ultimately decide to sell Mast Hill all, some, or none of the Purchase Shares that may be available for us to sell to Mast Hill pursuant to the Purchase Agreement. If and when we do elect to sell Purchase Shares to Mast Hill, Mast Hill may resell all, some, or none of those shares at any time or from time to time in its discretion, and such resales may be at different prices. As a result, investors who purchase shares of our common stock from Mast Hill in this offering at different times will likely pay different prices for those shares, and so may experience different levels of dilution and different outcomes in their investment results. Investors may experience a decline in the value of the shares of our common stock they purchase from Mast Hill as a result of future sales made by us to Mast Hill at prices lower than the prices such investors paid for their shares of our common stock in this offering. In addition, if we sell a substantial number of Purchase Shares to Mast Hill, or if investors expect that we will do so, the actual sales of those shares, or the mere existence of our arrangement with Mast Hill, 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.

Although the Purchase Agreement provides that we may sell up to an aggregate of $25,000,000 of Purchase Shares to Mast Hill, only 327,740 shares of our common stock (representing the maximum number of shares we may issue and sell under the Exchange Cap limitation) are being registered for resale under this prospectus, which includes the 79,900 Warrant Shares. If, after the Commencement Date, we elect to issue and sell to Mast Hill all shares of common stock being registered for resale under this prospectus, the actual gross proceeds from the sale of all such shares may be substantially less than the $25,000,000 available to us under the Purchase Agreement, depending on the market prices of our common stock during each applicable Valuation Period. If it becomes necessary for us to issue and sell to Mast Hill more shares than are being registered for resale under this prospectus in order to receive aggregate gross proceeds equal to $25,000,000, we must first obtain stockholder approval to issue shares of common stock in excess of the Exchange Cap in accordance with applicable Nasdaq rules. The number of shares of our common stock ultimately offered for sale by Mast Hill is dependent upon the number of Purchase Shares, if any, we ultimately sell to Mast Hill under the Purchase Agreement.

**Series A-1 Preferred Stock Holder** 

The shares of Common Stock being offered by holder of Series A-1 Preferred Stock are those issuable to Water Mill, upon conversion of, or otherwise pursuant to, the terms of shares of our Series A-1 Preferred Stock, issued by the Company to Water Mill pursuant to the Series A-1 Subscription Agreement. Because the conversion price

------

of the Series A-1 Preferred Stock may be adjusted, the number of shares of common stock that will actually be issued upon the conversion of or otherwise pursuant to the terms of the Series A-1 Preferred Stock cannot be ascertained at this time. In addition, under the terms of the Series A-1 Preferred Stock, a holder may not convert the Series A-1 Preferred Stock if such holder or any of its affiliates would beneficially own (to the extent that after giving effect to such conversion) a number of shares of common stock which would exceed 4.99% (which may be increased up to 9.99% upon prior notice from the holder of the Series A-1 Preferred Stock to us) of the shares of Common Stock outstanding immediately after giving effect to such conversion ("*Series A-1 Beneficial Ownership Limitation*").

**Series A-2 Preferred Stock Holders** 

The shares of Common Stock being offered by holders of Series A-2 Preferred Stock are those issuable to the Buyers, upon conversion of, or otherwise pursuant to, the terms of shares of our Series A-2 Preferred Stock, issued by the Company to the Buyers pursuant to the Series A-2 Subscription Agreement. Because the conversion price of the Series A-2 Preferred Stock may be adjusted, the number of shares of common stock that will actually be issued upon the conversion of or otherwise pursuant to the terms of the Series A-2 Preferred Stock cannot be ascertained at this time. The Series A-2 Certificate of Designation does not contain a beneficial ownership limitation similar to Series A-1 Beneficial Ownership Limitation.

The table below presents information regarding the Selling Stockholders and the shares of common stock that it may from time to time offer for resale under this prospectus. The table is prepared based on information supplied to us by the Selling Stockholders, and reflects its holdings as of August 20, 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 Stockholders may offer for resale under this prospectus, and is comprised of the Warrant Shares upon exercise of the Warrant we have issued to Mast Hill, the additional shares of Common Stock we may sell to Mast Hill from time to time as Purchase Shares under the Purchase Agreement, subject to the Exchange Cap limitation, and shares of the common stock upon the conversion of all outstanding shares of Series A-2 Preferred Stock into shares of common stock pursuant to the Certificate of Designation. The Selling Stockholders may sell some, all or none of the shares it receives in this offering. We do not know how long the Selling Stockholders will hold the shares before selling them, and we currently have no agreements, arrangements or understandings with the Selling Stockholders regarding the sale of any of the shares.

Beneficial ownership is determined in accordance with Rule 13d-3(d) promulgated by the SEC under the Exchange Act, and includes shares of our common stock with respect to which the Selling Stockholders have voting and investment power. Because the purchase price of the shares of common stock issuable under the Purchase Agreement is determined on the date of each Put Notice, the number of shares that we may actually sell under the Purchase Agreement may be fewer than the number of shares being offered by this prospectus.

**USE OF PROCEEDS** 

We intend to use the net proceeds from the sale of any securities offered by us under this prospectus for general corporate purposes unless otherwise indicated in the applicable prospectus supplement. General corporate purposes may include, but are not limited to, the acquisition of companies or businesses, repayment and refinancing of debt, investments in our subsidiaries, investments in existing or future projects, repurchasing or redeeming securities, working capital, and capital expenditures. We may temporarily invest the net proceeds in investment-grade, interest-bearing securities until they are used for their stated purpose. We have not determined the amount of net proceeds to be used specifically for such purposes or the timing of these expenditures, and the net proceeds from the sale of the securities have not been accounted for in our normal budgeting process. The amounts actually expended for these purposes may vary significantly and will depend on a number of factors, including the amount of cash we generate from future operations, the actual expenses of operating our business, and opportunities that may be or become available to us. As a result, management will retain broad discretion over the allocation of net proceeds. Additional information on the use of net proceeds we receive from the sale of securities covered by this prospectus may be set forth in the prospectus supplement relating to the specific offering.

We will not receive any proceeds in connection with the sale of any common stock offered by the Selling Stockholders. Each Selling Stockholder will pay expenses incurred by such Stockholder in connection with the sale of common stock from time to time.

**PLAN OF DISTRIBUTION** 

**Sales of Securities by the Company** 

We may sell the securities offered through this prospectus or any applicable prospectus supplement in any one or more of the following ways:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• directly to investors, including through a specific bidding, auction or other process;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to investors through agents;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• directly to agents;

to the public;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to one or more underwriters acting alone for resale to investors or to the public;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• through a block trade (which may involve crosses) in which the broker or dealer so engaged will attempt to sell
the securities as agent but may position and resell a portion of the block as principal to facilitate the transaction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ordinary brokerage transactions and transactions in which the broker solicits purchasers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• in "at the market offerings," within the meaning of Rule 415(a)(4) of the Securities Act, to or
through a market maker or into an existing trading market, on an exchange or otherwise;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• transactions not involving market makers or established trading markets, including direct sales or privately
negotiated transactions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• exchange distributions and/or secondary distributions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• by delayed delivery contracts or by remarketing firms;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• transactions in options, swaps, or other derivatives that may or may not be listed on an exchange; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• through a combination of any such methods of sale.

We reserve the right to sell securities directly to investors on our own behalf in those jurisdictions where we are authorized to do so.

The securities may be distributed at a fixed price or prices, which may be changed, market prices prevailing at the time of sale, prices related to the prevailing market prices, or negotiated prices. Any of the prices may represent a discount from the prevailing market prices. In the sale of the securities, underwriters, dealers, or agents may receive compensation from us or from purchasers of the securities, for whom they may act as agents, in the form of discounts, concessions, or commissions. Underwriters may sell the securities to or through dealers, and such dealers may receive compensation in the form of discounts, concessions, or commissions from the underwriters and/or commissions from the purchasers for whom they may act as agents. Underwriters, dealers, and agents that participate in the distribution of the securities may be deemed to be underwriters under the Securities Act and any discounts or commissions they receive from us and any profit on the resale of securities they realize may be deemed to be underwriting discounts and commissions under the Securities Act. The prospectus supplement will, where applicable, describe, disclose, or identify:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the terms of the offering;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any underwriters, dealers, or agents;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any managing underwriter or underwriters;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the purchase price of the securities;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the net proceeds from the sale of the securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any delayed delivery arrangements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any underwriting discounts, commissions, and other items constituting underwriters' compensation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any initial public offering price;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any commissions paid to agents.

Any underwritten offering may be on a best efforts or a firm commitment basis. If underwriters are used in the sale, the underwriters will acquire the securities for their own account, including through underwriting, purchase, security lending or repurchase agreements with us. The underwriters may resell the securities from time to time in one or more transactions, including negotiated transactions. Underwriters may sell the securities in order to facilitate transactions in any of our other securities (described in this prospectus or otherwise), including other public or private transactions and short sales. Underwriters may offer securities to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. Unless otherwise indicated in the prospectus supplement, the obligations of the underwriters to purchase the securities will be subject to certain conditions, and the underwriters will be obligated to purchase all the offered securities if they purchase any of them. The underwriters may change from time to time any initial public offering price and any discounts or concessions allowed or re-allowed or paid to dealers.

If dealers are used in the sale of securities offered through this prospectus, we will sell the securities to them as principals. They may then resell those securities to the public at varying prices determined by the dealers at the time of resale. The prospectus supplement will include the names of the dealers and the terms of the transaction.

We may sell the securities offered through this prospectus directly or through agents designated from time to time. The prospectus supplement will name any agent involved in the offer or sale of the offered securities and will describe any commissions payable to the agent. Unless otherwise indicated in the prospectus supplement, any agent will agree to use its reasonable best efforts to solicit purchases for the period of its appointment.

We may sell the securities directly to institutional investors or others who may be deemed to be underwriters within the meaning of the Securities Act with respect to any sale of those securities. The terms of any such sales will be described in the prospectus supplement.

We may also make direct sales through subscription rights distributed to our stockholders on a pro rata basis, which may or may not be transferable. In any distribution of subscription rights to stockholders, if all of the underlying securities are not subscribed for, we may then sell the unsubscribed securities directly to third parties or may engage the services of one or more underwriters, dealers or agents, including standby underwriters, to sell the unsubscribed securities to third parties.

If indicated in the applicable prospectus supplement, securities may also be offered or sold by a "remarketing firm" in connection with a remarketing arrangement contemplated by the terms of the securities. Remarketing firms may act as principals for their own accounts or as agents. The applicable prospectus supplement will identify any remarketing firm and the terms of its agreement, if any, with us. It will also describe the remarketing firm's compensation. Remarketing firms may be deemed to be underwriters in connection with the remarketing of the securities.

If the prospectus supplement indicates, we may authorize agents, underwriters or dealers to solicit offers from certain types of institutions to purchase securities at the public offering price under delayed delivery contracts. These contracts would provide for payment and delivery on a specified date in the future. The contracts would be subject only to those conditions described in the prospectus supplement. The applicable prospectus supplement will describe the commission payable for solicitation of those contracts.

------

We may from time to time engage a firm or firms to act as our agent for one or more offerings of our securities. We sometimes refer to any such agent as our "offering agent." If we reach agreement with an offering agent with respect to a specific offering, including the number of securities and any minimum price below which sales may not be made, than the offering agent will try to sell such securities on the agreed terms. The offering agent could make sales in privately negotiated transactions or any other method permitted by law, including sales deemed to be an "at the market" offering as defined in Rule 415 promulgated under the Securities Act, including sales made directly on an exchange, or sales made to or through a market maker other than on an exchange. Any such offering agent will be deemed to be an "underwriter" within the meaning of the Securities Act with respect to any sales effected through an "at the market" offering.

Unless the applicable prospectus supplement states otherwise, each series of offered securities will be a new issue and will have no established trading market, other than shares of our common stock, which are listed The Nasdaq Capital Market. We may elect to list any series of offered securities on an exchange. Any underwriters that we use in the sale of offered securities may make a market in such securities, but may discontinue such market making at any time without notice. Therefore, we cannot assure you that the securities will have a liquid trading market.

Any underwriter may also engage in stabilizing transactions, syndicate covering transactions and penalty bids in accordance with Rule 104 under the Exchange Act. Stabilizing transactions involve bids to purchase the underlying security in the open market for the purpose of pegging, fixing or maintaining the price of the securities. Syndicate covering transactions involve purchases of the securities in the open market after the distribution has been completed in order to cover syndicate short positions.

Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when the securities originally sold by the syndicate member are purchased in a syndicate covering transaction to cover syndicate short positions. Stabilizing transactions, syndicate covering transactions and penalty bids may cause the price of the securities to be higher than it would be in the absence of the transactions. The underwriters may, if they commence these transactions, discontinue them at any time.

We, the underwriters, dealers, or other agents may engage in derivative transactions involving the securities. These derivatives may consist of short sale transactions and other hedging activities. The underwriters, dealers, or agents may acquire a long or short position in the securities, hold or resell securities acquired and purchase options or futures on the securities and other derivative instruments with returns linked to or related to changes in the price of the securities. In order to facilitate these derivative transactions, we may enter into security lending or repurchase agreements with the underwriters, dealers, or agents. The underwriters, dealers, or agents may effect the derivative transactions through sales of the securities to the public, including short sales, or by lending the securities in order to facilitate short sale transactions by others. The underwriters, dealers, or agents may also use the securities purchased or borrowed from us or others (or, in the case of derivatives, securities received from us in settlement of those derivatives) to directly or indirectly settle sales of the securities or close out any related open borrowings of the securities.

We may also make sales through the Internet or through other electronic means. Since we may from time to time elect to offer securities directly to the public, with or without the involvement of agents, underwriters, or dealers, utilizing the Internet or other forms of electronic bidding or ordering systems for the pricing and allocation of such securities, you will want to pay particular attention to the description of that system we will provide in a prospectus supplement. Such electronic system may allow bidders to directly participate, through electronic access to an auction site, by submitting conditional offers to buy that are subject to acceptance by us, and which may directly affect the price or other terms and conditions at which such securities are sold. These bidding or ordering systems may present to each bidder, on a so-called "real-time" basis, relevant information to assist in making a bid, such as the clearing spread at which the offering would be sold, based on the bids submitted, and whether a bidder's individual bids would be accepted, prorated or rejected.

------

Upon completion of such an electronic auction process, securities will be allocated based on prices bid, terms of bid or other factors. The final offering price at which securities would be sold and the allocation of securities among bidders would be based in whole or in part on the results of the Internet or other electronic bidding process or auction. Agents, underwriters, and dealers may be entitled, under agreements entered into with us, to indemnification by us against certain liabilities, including liabilities under the Securities Act. Our agents, underwriters, and dealers, or their affiliates, may be customers of, engage in transactions with or perform services for us, in the ordinary course of business.

To comply with applicable state securities laws, the securities offered by this prospectus will be sold, if necessary, in such jurisdictions only through registered or licensed brokers or dealers. In addition, securities may not be sold in some states unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

**Sales of Common Stock by the Selling Stockholders** 

As of the date of this prospectus, we have not been advised by any selling stockholder as to any plan of distribution. The Selling Stockholders may sell or distribute its shares of our common stock from time to time 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 the sale, at prices related to the prevailing market prices, at negotiated prices, or at fixed prices. The sale of shares offered by this prospectus could be effected in one or more of the following methods:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ordinary brokerage transactions and transactions in which the broker solicits purchasers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a block trade in which the broker-dealer so engaged will attempt to sell the shares as agent, but may position
and resell a portion of the block as principal to facilitate the transaction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• through brokers, dealers, or underwriters who may act solely as agents;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• "at the market" into an existing market for the shares;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• in other ways not involving market makers or established business markets, including direct sales to purchasers
or sales effected through agents;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• in privately negotiated transactions; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any combination of the foregoing.

The Selling Stockholders may also sell shares of common stock under Rule 144 promulgated under the Securities Act, if available, rather than under this prospectus. In addition, the Selling Stockholders may transfer the shares of common stock by other means not described in this prospectus. If the Selling Stockholders effect such transactions by selling shares of common stock to or through underwriters, broker-dealers or agents, such underwriters, broker-dealers or agents may receive commissions in the form of discounts, concessions or commissions from the Selling Stockholders or commissions from purchasers of the shares of common stock for whom they may act as agent or to whom they may sell as principal (which discounts, concessions or commissions as to particular underwriters, broker-dealers or agents may be in excess of those customary in the types of transactions involved). In connection with sales of the shares of common stock or otherwise, the Selling Stockholders may enter into hedging transactions with broker-dealers, which may in turn engage in short sales of the shares of common stock in the course of hedging in positions they assume. If the Company elects to waive, in whole or in part, the restrictions on short sales by one or more Selling Stockholders in the Purchase Agreement, the Selling Stockholders would be permitted to also sell shares of common stock short and deliver shares of common stock, as applicable, covered by this prospectus to close out short positions and to return borrowed shares in connection with such short sales. The Selling Stockholders may also loan or pledge shares of common stock to broker-dealers that in turn may sell such shares.

------

The Selling Stockholders may pledge or grant a security interest in securities owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of common stock from time to time pursuant to this prospectus or any amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act amending, if necessary, the list of Selling Stockholders to include the pledgee, transferee or other successors in interest as selling stockholders under this prospectus. The Selling Stockholders also may transfer and donate the shares of common stock in other circumstances in which case the transferees, donees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.

Under the securities laws of some states, the shares of common stock may be sold in such states only through registered or licensed brokers or dealers. In addition, in some states the shares of common stock may not be sold unless such shares have been registered or qualified for sale in such state or an exemption from registration or qualification is available and is complied with.

There can be no assurance that any Selling Stockholder will sell any or all of the shares of common stock registered pursuant to the registration statement, of which this prospectus forms a part.

*Statutory Underwriter; Regulation M* 

Mast Hill is an "underwriter" within the meaning of Section 2(a)(11) of the Securities Act. As an underwriter, Mast Hill is required to comply with certain requirements of the Securities Act and the Exchange Act, including Regulation M. With certain exceptions, Regulation M precludes Mast Hill, 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 that 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.

Except as disclosed in this prospectus, we know of no existing arrangements between Mast Hill or any other stockholder, broker, dealer, underwriter or agent relating to the sale or distribution of the shares of our common stock offered by this prospectus.

[Mast Hill has informed us that it intends to use one or more registered broker-dealers to effectuate all sales, if any, of our common stock that it has acquired and may in the future acquire from us pursuant to the Purchase Agreement. Each such registered broker-dealer will be an underwriter within the meaning of Section 2(a)(11) of the Securities Act. Mast Hill has informed us that each such broker-dealer will receive commissions from Mast Hill that will not exceed customary brokerage commissions.] Except as disclosed in this prospectus, we know of no existing arrangements between Mast Hill or any other stockholder, broker, dealer, underwriter or agent relating to the sale or distribution of the shares of our common stock offered by this prospectus.

To the extent required by the Securities Act and the rules and regulations thereunder, any broker-dealer participating in the distribution of the shares of common stock may be deemed to be "underwriters" within the meaning of the Securities Act, and any commission paid, or any discounts or concessions allowed to, any such broker-dealer may be deemed to be underwriting commissions or discounts under the Securities Act. At the time a particular offering of the shares of common stock is made, a prospectus supplement, if required, will be distributed, which will set forth the aggregate amount of shares of common stock being offered and the terms of the offering, including the name or names of any broker-dealers or agents, any discounts, commissions and other terms constituting compensation from the selling stockholders and any discounts, commissions or concessions allowed or re-allowed or paid to broker-dealers.

The Selling Stockholders and any other person participating in distribution of the shares of common stock will be subject to applicable provisions of the Securities Exchange, and the rules and regulations thereunder, including, without limitation, to the extent applicable, Regulation M of the Exchange Act, which may limit the timing of purchases and sales of any of the shares of common stock by the Selling Stockholders and any other participating

------

person. To the extent applicable, Regulation M may also restrict the ability of any person engaged in the distribution of the shares of common stock to engage in market-making activities with respect to the shares of common stock. All of the foregoing may affect the marketability of the common stock and the ability of any person or entity to engage in market-making activities with respect to the shares of common stock.

**Nasdaq Listing** 

Our common stock is listed on The Nasdaq Capital Market under the symbol "TCRT." On August 19, 2025, the last reported sale price of our common stock on The Nasdaq Capital Market was $2.24 per share.

**PART II** 

**INFORMATION NOT REQUIRED IN PROSPECTUS** 

**Item 14. *Other Expenses of Issuance and Distribution*** 

The fees and expenses, other than underwriting discounts and commission, payable by us in connection with the resale of the shares in this offering are as follows:

---

| | |
|:---|:---|
|  SEC registration fee | $7938 |
|  FINRA filing fees | \* |
|  Printing expenses | \* |
|  Legal fees and expenses | \* |
|  Accounting fees and expenses | \* |
|  Miscellaneous fees and expenses | \* |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **Total\*** | $7938 |

---

\* All amounts are estimates, other than the SEC's registration fee. 

We will bear all costs, expenses, and fees in connection with the registration of the securities, including with regard to compliance with state securities laws. The Selling Stockholders, however, will bear all underwriting fees, discounts, and commissions due to underwriters, brokers-dealers, or agents in connection with the sale of common stock by the Selling Stockholders.

**Item 15. *Indemnification of Directors and Officers*** 

Section 145 of the Delaware General Corporation Law ("*DGCL*") provides that a corporation may indemnify directors and officers as well as other employees and individuals against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with any threatened, pending or completed actions, suits or proceedings in which such person is made a party by reason of such person being or having been a director, officer, employee or agent of the Registrant. The DGCL provides that Section 145 is not exclusive of other rights to which those seeking indemnification may be entitled under any bylaws, agreement, vote of stockholders or disinterested directors or otherwise. The Registrant's Third Amended and Restated Certificate of Incorporation (the "*Certificate of Incorporation*") and Amended and Restated Bylaws (the "*Bylaws*") provide for indemnification by the Registrant of its directors and officers to the fullest extent permitted by the DGCL.

Section 102(b)(7) of the DGCL permits a corporation to provide in its Certificate of Incorporation that a director of the corporation shall not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability (1) for any breach of the director's duty of loyalty to the corporation or its stockholders, (2) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (3) for unlawful payments of dividends or unlawful stock repurchases, redemptions or other distributions or (4) for any transaction from which the director derived an improper personal benefit. The Registrant's Certificate of Incorporation provides for such limitation of liability to the fullest extent permitted by the DGCL.

The Registrant has entered into indemnification agreements with each of its directors and executive officers to provide contractual indemnification in addition to the indemnification provided in the Registrant's Bylaws. Each indemnification agreement provides for indemnification and advancements by the Registrant of certain expenses and costs relating to claims, suits or proceedings arising from his or her service to the Registrant or, at our request, service to other entities, as officers or directors to the maximum extent permitted by applicable law. We believe that these provisions and agreements are necessary to attract qualified directors.

------

The Registrant also maintains standard policies of insurance under which coverage is to be provided (1) to its directors and officers against loss arising from claims made by reason of breach of duty or other wrongful act, while acting in their capacity as directors and officers of the Registrant, and (2) to the Registrant with respect to payments which may be made by the Registrant to such officers and directors pursuant to any indemnification provision contained in the Registrant's Certificate of Incorporation and Bylaws or otherwise as a matter of law.

\* Filed herewith.

\*\* To be filed if necessary, subsequent to the effectiveness of this registration statement by an amendment to this registration statement or incorporated by reference pursuant to a Current Report on Form 8-K in connection with the offering of securities.

**Item 17. *Undertakings*** 

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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration
Fee" table in the effective registration statement; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 (1)(i),(1)(ii) and (1)(iii) of this section do not apply if information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished

------

to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 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 part of the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective
amendment shall be deemed to be a new registration statement relating to the securities offered herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the
registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration
statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act of 1933 shall be deemed to be
part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As
provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration
statement to which the prospectus related, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. *Provided*, *however*, that no statement made in a registration statement or
prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time
of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such
effective date.

(5) That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any
purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used
to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell
such securities to such purchaser:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be
filed pursuant to Rule 424;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or
used or referred to by the undersigned registrant;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) The portion of any other free writing prospectus relating to the offering containing material information about
the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report

------

pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement 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.

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 of 1933 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 of 1933 and will be governed by the final adjudication of such issue.

The undersigned registrant hereby undertakes to file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of Section 310 of the Trust Indenture Act of 1939 (the "Trust Indenture Act") in accordance with the rules and regulations prescribed by the Securities and Exchange Commission under Section 305(b)(2) of the Trust Indenture Act.

------

***Re: Registration Statement on Form S-3 Ladies and Gentlemen:***

We have acted as counsel to Alaunos Therapeutics, Inc., a Delaware corporation (the "Company"), in connection with the preparation and filing with the Securities and Exchange Commission (the "Commission") of a registration statement on Form S-3 (the "Registration Statement") under the Securities Act of 1933, as amended (the "Securities Act"), relating to the registration by the Company of the offer and sale by the Company from time to time, pursuant to Rule 415 under the Securities Act, of (i) shares of the Company's common stock, par value $0.001 per share ("Common Stock"); (ii) shares of the Company's preferred stock, par value $0.001 per share ("Preferred Stock"); (iii) debt securities of the Company ("Debt Securities"); and (iv) warrants to purchase Common Stock, Preferred Stock, or Debt Securities ("Warrants" and, together with the Common Stock, Preferred Stock, and Debt Securities, the "Primary Securities"), with an aggregate initial offering price not to exceed $50,000,000.

The Registration Statement also relates to the registration of the resale by certain selling stockholders named in the Registration Statement (the "Selling Stockholders") of up to 772,302 shares of Common Stock (the "Resale Shares"), consisting of (a) up to 247,840 shares of Common Stock that may be issued and sold to Mast Hill Fund, L.P. ("Mast Hill") from time to time pursuant to the Equity Purchase Agreement, dated as of May 19, 2025 (the "Purchase Agreement"); (b) up to 79,900 shares of Common Stock issuable upon the exercise of the warrant issued to Mast Hill pursuant to the Purchase Agreement; (c) up to 217,391 shares of Common Stock issuable upon conversion of or otherwise pursuant to the terms of the 500 shares of the Company's Series A-1 Convertible Preferred Stock issued pursuant to the Subscription Agreement, dated April 11, 2025; and (d) up to 227,171 shares of Common Stock issuable upon conversion of or otherwise pursuant to the terms of the 850 shares of the Company's Series A-2 Convertible Preferred Stock issued pursuant to the Subscription Agreement, dated June 24, 2025.

The Primary Securities may be offered and sold by the Company from time to time as set forth in the Registration Statement, the prospectus contained therein (the "Prospectus"), and supplements to the Prospectus (each, a "Prospectus Supplement"). The Debt Securities are to be issued under one or more indentures (each, an "Indenture") to be entered into between the Company and a trustee or trustees thereunder (each, a "Trustee"). The forms of Indenture have been filed as exhibits to the Registration Statement. The Warrants may be issued under one or more warrant agreements (each, a "Warrant Agreement"), each to be entered into between the Company and a bank or trust company, as warrant agent. The Resale Shares are to be offered and sold by the Selling Stockholders as set forth in the Registration Statement and the Prospectus. In that connection, we have examined originals, or copies certified or otherwise identified to our satisfaction, of such documents, corporate records, and other instruments as we have deemed necessary for the purposes of this opinion, including (i) the organizational

------

documents of the Company, including the Third Amended and Restated Certificate of Incorporation, as amended, and the Amended and Restated Bylaws, as amended; (ii) minutes and records of the corporate proceedings of the Company with respect to the issuance and sale of the Primary Securities and the Resale Shares, including the proceedings of the board of directors of the Company; (iii) the Registration Statement, including the exhibits thereto; (iv) the Prospectus; (v) the forms of Indenture; (vi) the Purchase Agreement, the warrant issued to Mast Hill, the Subscription Agreements, and the Certificates of Designation for the Series A-1 and Series A-2 Convertible Preferred Stock; and (vii) such other documents and records as we have deemed necessary or appropriate for purposes of this opinion. For purposes of this opinion, we have assumed the authenticity of all documents submitted to us as originals, the conformity to the originals of all documents submitted to us as copies, and the authenticity of the originals of all documents submitted to us as copies. We have also assumed the legal capacity of all natural persons, the genuineness of the signatures of persons signing all documents in connection with which this opinion is rendered, the authority of such persons signing on behalf of the parties thereto other than the Company, and the due authorization, execution, and delivery of all documents by the parties thereto other than the Company. We have not independently established or verified any facts relevant to the opinions expressed herein, but have relied upon statements and representations of the officers and other representatives of the Company.

The foregoing opinions are based upon and expressly limited to the laws of the State of Nevada. To the extent that the opinions expressed herein involve conclusions as to matters governed by the laws of the State of Delaware (including the Delaware General Corporation Law) or the State of New York, we have assumed, without independent investigation, that such laws are identical in all material respects to the laws of the State of Nevada. The opinions expressed in this opinion letter are based on the laws as in effect on the date hereof. We are not opining on, and we assume no responsibility for, the applicability to or effect on any of the matters covered herein of (a) the laws of any other jurisdiction; or (b) the laws of any county, municipality or other political subdivision or local governmental agency or authority. This opinion letter is given as of the date hereof. Our opinions herein are expressed solely with respect to the applicable laws of the State of Nevada that, in our experience, are normally applicable to transactions of the type contemplated by the Registration Statement. The opinion set forth herein related to the Indenture and Warrants assumes that such documents are governed by New York law, and we have assumed that New York law is identical to Nevada law in relevant respects. The opinions set forth herein are made as of the date hereof and are subject to, and may be limited by, future changes in the factual matters set forth herein, and we undertake no duty to advise you of the same that may occur after the Registration Statement becomes effective. The opinions expressed herein are based upon the law in effect (and published or otherwise generally available) on the date hereof, which laws are subject to change with possible retroactive effect, and we assume no obligation to revise or supplement these opinions should such law be changed by legislative action, judicial decision or otherwise after the Registration Statement becomes effective. In rendering our opinions, we have not considered, and hereby disclaim any opinion as to, the application or impact of any laws, cases, decisions, rules or regulations of any other jurisdiction, court or administrative agency.

Based upon the foregoing and subject to the assumptions, exceptions, qualifications, and limitations set forth herein, we are of the opinion that:

if any, for the shares of Preferred Stock have been duly executed by the Company, countersigned by the transfer agent therefor, and duly delivered to the purchasers thereof against payment therefor, then the shares of Preferred Stock, when issued

conversion of any convertible Debt Securities in accordance with their terms, or upon exercise of any Warrants in accordance with their terms, will be validly issued, fully paid, and nonassessable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. With respect to the Warrants proposed to be sold by the Company, assuming that: (a) the Registration
Statement and any required post-effective amendment thereto have become effective under the Securities Act and the Prospectus and any and all Prospectus Supplement(s) required by applicable laws have been delivered and filed as required by such

delivered purchase, underwriting, or similar agreement, will be valid and legally binding obligations of the Company, enforceable against the Company in accordance with their terms, except as enforcement thereof may be limited by bankruptcy,
insolvency, reorganization, moratorium, or other similar laws relating to or affecting creditors' rights generally, and by general equitable principles (regardless of whether such enforceability is considered in a proceeding at law or in
equity).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. With respect to the Resale Shares, such shares have been, or when issued upon exercise of the warrant issued
to Mast Hill or conversion of the Series A-1 Convertible Preferred Stock or Series A-2 Convertible Preferred Stock in accordance with their respective terms as set forth
