Up to 45,454,545 Units consisting of

45,454,545 Shares of Common Stock or 45,454,545 Pre-Funded Warrants to purchase

45,454,545 Shares of Common Stock and

45,454,545 Common Warrants to purchase up to 45,454,545 Shares of Common Stock

Up to 45,454,545 Shares of Common Stock Underlying the Pre-Funded Warrants

Up to 45,454,545 Shares of Common Stock Underlying the Common Warrants

We are offering on a reasonable best efforts basis up to 45,454,545 units, each unit consisting of one share of common stock and one common warrant to purchase one share of common stock, at an assumed offering price of $0.22 per unit, which is equal to the closing price of our common stock on the Nasdaq Capital Market on October 20, 2023 for gross proceeds of up to $10,000,000. The common warrants included in the units will have an exercise price of $0.22 per share (equal to 100% of the public offering price of each unit sold in this offering), will be exercisable immediately and will expire five (5) years from the date of issuance. We are also offering the shares of our common stock that are issuable from time to time upon the exercise of the common warrants included in the units.

We are also offering to certain purchasers whose purchase of units in this offering would otherwise result in the purchaser, together with its affiliates and certain related parties, beneficially owning more than 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding common stock immediately following the consummation of this offering, the opportunity to purchase, if any such purchaser so chooses, pre-funded units, each pre-funded unit consisting of one pre-funded warrant to purchase one share of common stock and the same common warrant described above with each share of common stock, in lieu of units that would otherwise result in such purchaser's beneficial ownership exceeding 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding common stock. The purchase price of each pre-funded unit will be equal to the price per unit being sold to the public in this offering, minus $0.0001, and the exercise price of each pre-funded warrant included in the pre-funded units will be $0.0001 per share. The pre-funded warrants will be exercisable immediately and may be exercised at any time until all of the pre-funded warrants are exercised in full. For each pre-funded unit we sell, the number of units (and shares of common stock) we are offering will be decreased on a one-for-one basis. This offering also relates to the shares of common stock issuable upon the exercise of the pre-funded warrants and the common warrants included in the pre-funded units.

The shares of common stock or pre-funded warrants, as the case may be, and the common warrants included in the units or the pre-funded units, can only be purchased together in this offering, but the securities contained in the units or pre-funded units will be issued separately and will be immediately separable upon issuance. We are also registering the shares of common stock issuable from time to time upon exercise of the common warrants and pre-funded warrants included in the units offered hereby.

The securities will be offered at a fixed price and are expected to be issued in a single closing. The offering will terminate on November 14, 2023, unless completed sooner or unless we decide to terminate the offering (which we may do at any time in our discretion) prior to that date; however, notwithstanding the foregoing, the shares of our common stock underlying the pre-funded warrants and the common warrants will be offered on a continuous basis pursuant to Rule 415 under the Securities Act of 1933, as amended. We expect this offering to be completed not later than two business days following the commencement of sales in this offering (after the effective date of the registration statement of which this prospectus forms a part) and we will deliver all securities to be issued in connection with this offering delivery versus payment or receipt versus payment, as the case may be, upon receipt of investor funds received by us. Accordingly, neither we nor the placement agent have made any arrangements to place investor funds in an escrow account or trust account since the placement agent will not receive investor funds in connection with the sale of the securities offered hereunder.

We have engaged Maxim Group LLC (the "placement agent" or "Maxim"), to act as our exclusive placement agent in connection with this offering. The placement agent has agreed to use its reasonable best efforts to arrange for the sale of the securities offered by this prospectus. The placement agent is not purchasing or selling any of the securities we are offering and the placement agent is not required to arrange the purchase or sale of any specific number of securities or dollar amount. We have agreed to pay to the placement agent the placement agent fees set forth in the table below, which assumes that we sell all of the securities offered by this prospectus. There is no arrangement for funds to be received in escrow, trust or similar arrangement. There is no minimum offering requirement as a condition of closing of this offering. We may sell fewer than all of the units and pre-funded units offered hereby, which may significantly reduce the amount of proceeds received by us. Because there is no escrow account and no minimum number of securities or amount of proceeds, investors could be in a position where they have invested in us, but we have not raised sufficient proceeds in this offering to adequately fund the intended uses of the proceeds as described in this prospectus. See " Risk Factors " for more information regarding risks related to this offering. We will bear all costs associated with the offering. See " Plan of Distribution " for more information regarding these arrangements.

Our common stock is listed on the Nasdaq Capital Market under the symbol "BKYI." On October 20, 2023, the closing price of our common stock on the Nasdaq Capital Market was $0.22 per share. The actual public offering price per unit or pre-funded unit, as the case may be, will be determined through negotiation among us, the placement agent and the investors in the offering based on market conditions at the time of pricing, and may be at a discount to the current market price of our common stock. Therefore, the assumed public offering price used throughout this prospectus may not be indicative of the final offering price. There is no established trading market for the pre-funded warrants or the common warrants, and we do not expect a market to develop. We do not intend to apply for a listing of the units, the pre-funded units, the pre-funded warrants, or the common warrants on any securities exchange or other nationally recognized trading system. Without an active trading market, the liquidity of the pre-funded warrants and the common warrants will be limited.

Prospectus summary 34 changes

13 unchanged paragraphs

We recently disclosed the following results of operation for the three and nine months ended September 30, 2023 and balance sheet data at September 30, 2023.

Revenues in the quarter ended September 30, 2023 rose 33% to $1.8 million as compared to $1.4 million the third quarter of 2022 reflecting increased services, software license, and hardware revenue. Third quarter service revenue was driven by custom service installations for new and existing customer deployments and upgrades, hardware revenue from new contract activity, and progress in reducing hardware inventories. For the first nine months of 2023, total revenues rose 30% to $6.8 million as compared to $5.3 million for the first nine months of 2022, reflecting growth in service and license revenue and a decline in hardware revenue.

Gross profit grew 43% to $1.4 million in the third quarter of 2023 from $1.0 million in third quarter of 2022, reflecting an increase in gross margin to 77% from 71% in the third quarter of 2022. Gross profit and gross margin benefitted from a year-over-year increase in higher margin services and software license revenue and a decrease in third-party software costs, due principally to the seasonal, vacation-related slowdown in third quarter business activity in Europe.

Third quarter 2023 operating expenses decreased 36% to $2.2 million from $3.3 million in the corresponding period in 2022 due primarily to lower selling, general and administrative expenses reflecting progress in our expense reduction initiatives as well as lower research and development investments. We continue to focus on expense reductions to further benefit operating results.

Reflecting higher gross profit and lower operating costs, we reduced our third quarter net loss to $749,000 as compared to $2.4 million in the third quarter of 2022. Similarly, we reduced our year-to-date 2023 net loss to $2.5 million from a net loss of $5.1 million for the first nine months of 2022.

At September 30, 2023, we had current assets of $7.9 million, including $0.3 million of cash and cash equivalents, $2.9 million of accounts receivable, and $4.3 million of inventory.

Units to be Offered:

Up to 45,454,545 units, each unit consisting of one share of common stock and one common warrant to purchase one share of common stock.

Pre-funded Units to be Offered:

We are also offering to certain purchasers whose purchase of units in this offering would otherwise result in the purchaser, together with its affiliates, beneficially owning more than 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding common stock immediately following the consummation of this offering, the opportunity to purchase, if such purchasers so choose, pre-funded units, consisting of one pre-funded warrant to purchase one share of common stock and one common warrant to purchase one share of common stock. The purchase price of each pre-funded unit will equal the price per unit being sold to the public in this offering, minus $0.0001, and the exercise price of each pre-funded warrant will be $0.0001 per share of common stock. For each pre-funded unit we sell, the number of units we are offering will be decreased on a one-for-one basis. This offering also relates to the shares of common stock issuable upon the exercise of any pre-funded warrants or common warrants comprising the pre-funded unit sold in this offering.

Description of Common Warrants:

Each common warrant will have an exercise price of $[●] per share (equal to 100% of the public offering price of each unit sold in this offering), will be immediately exercisable, and will expire on the five (5) year anniversary of the original issuance date. This prospectus also relates to the offering of the shares of common stock issuable upon exercise of the common warrants.

Common Stock Outstanding after this

Up to 54,893,439 shares (assuming the sale of the maximum number of units covered by this prospectus, no sale of pre-funded units, and no exercise of the common warrants issued in this offering).

Assuming the maximum number of units are sold in this offering at an assumed public offering price of $0.22 per unit, which represents the closing price of our common stock on the Nasdaq Capital Market on October 20, 2023, and assuming no issuance of pre-funded warrants in connection with this offering, we estimate that the net proceeds from our sale of units in this offering will be approximately $9,120,000, after deducting the placement agent fees and estimated offering expenses payable by us. However, this is a reasonable best efforts offering with no minimum number of securities or amount of proceeds as a condition to closing, and we may not sell all or any of these securities offered pursuant to this prospectus; as a result, we may receive significantly less in net proceeds. We currently intend to use the net proceeds from this offering (i) to repay up to $2.2 million of outstanding indebtedness as determined by the Company, and (ii) the balance, if any, will be used for general corporate and working capital purposes and to fund ongoing operations and expansion of our business. For additional information please refer to the section entitled " Use of Proceeds " on page 10 of this prospectus.

Listing of Common Stock:

Our common stock is listed on the Nasdaq Capital Market under the ticker symbol "BKYI". There is no established trading market for the common warrants or the pre-funded warrants, and we do not expect a trading market to develop. We do not intend to list the common warrants or the pre-funded warrants on any securities exchange or other trading market. Without a trading market, the liquidity of the common warrants and the pre-funded warrants will be extremely limited.

Reasonable Best Efforts Offering:

We have agreed to offer and sell the securities offered hereby to the purchasers through the placement agent. The placement agent is not required to buy or sell any specific number or dollar amount of the securities offered hereby, but it will use its reasonable best efforts to solicit offers to purchase the securities offered by this prospectus. See " Plan of Distribution " beginning on page 19 of this prospectus.

The number of shares of our common stock to be outstanding after this offering is based on 9,438,894 shares of our common stock outstanding as of October 20, 2023 and excludes as of such date:

166,234 shares of our common stock issuable upon the exercise of stock options, with a weighted-average exercise price of $17.30 per share;

4,864,150 shares of our common stock issuable upon the exercise of outstanding warrants, with a weighted-average exercise price of $5.82 per share;

Unless otherwise indicated, this prospectus assumes no issuance of pre-funded warrants in connection with this offering and no exercise of the common warrants offered hereby.

Investing in our securities involves a high degree of risk. Before deciding to invest in our securities, you should consider carefully the risks and uncertainties described below and under Item 1A. " Risk Factors " in our Annual Report on Form 10-K, filed with the Securities and Exchange Commission, or SEC, on June 1, 2023, which are each incorporated by reference in this prospectus, together with all of the other information contained in this prospectus and documents incorporated by reference herein, and in any free writing prospectus that we have authorized for use in connection with this offering. If any of the matters discussed in the following risk factors were to occur, our business, financial condition, results of operations, cash flows or prospects could be materially adversely affected, the market price of our common stock could decline and you could lose all or part of your investment in our securities. Additional risks and uncertainties not presently known or which we consider immaterial as of the date hereof may also have an adverse effect on our business.

1 unchanged paragraph

This is a reasonable best efforts offering, with no minimum amount of securities required to be sold, and we may sell fewer than all of the securities offered hereby.

The placement agent has agreed to use its reasonable best efforts to solicit offers to purchase the units and pre-funded units in this offering. The placement agent has no obligation to buy any of the securities from us or to arrange for the purchase or sale of any specific number or dollar amount of the securities. There is no required minimum number of securities that must be sold as a condition to completion of this offering. As there is no minimum offering amount required as a condition to the closing of this offering, the actual offering amount, placement agent fees and proceeds to us are not presently determinable and may be substantially less than the maximum amounts set forth above. We may sell fewer than all of the securities offered hereby, which may significantly reduce the amount of proceeds received by us, and investors in this offering will not receive a refund in the event that we do not sell all of the units or pre-funded units offered in this offering. The success of this offering will impact our ability to use the proceeds to execute our business plans. We may have insufficient capital to implement our business plans and satisfy current obligations, potentially resulting in greater operating losses or dilution unless we are able to raise the required capital from alternative sources. There is no assurance that alternative capital, if needed, would be available on terms acceptable to us, or at all.

If we do not realize net proceeds in this offering sufficient to repay our $2.2 million principal amount note in full, unless we generate sufficient cash flow from operations we will need to obtain additional financing to operate our business, which may not be available. If we are unable to raise additional capital or generate sufficient revenue, we may not be able to continue operations.

We have historically financed our operations through access to the capital markets by issuing secured and convertible debt securities, convertible preferred stock, common stock, and through factoring receivables. During 2022 and the first six months of 2023, we did not generate sufficient revenues to cover operating expenses. Our $2.2 million principal amount note is due December 22, 2023 and we intend to use certain of the proceeds from this offering to repay all or part of the note. If we do not realize net proceeds in this offering sufficient to repay the note in full and are unable to generate sufficient revenue to repay the balance of the note and cover operating expenses in future periods, we will need to obtain additional third-party financing. We may, therefore, need to obtain additional financing through the issuance of debt or equity securities. We cannot assure you that we will be able to secure any such additional financing on terms acceptable to us or at all. If we cannot obtain such financing, we will not be able to execute our business plan, will be required to reduce operating expenses, and in the extreme case, discontinue operations.

You will experience immediate dilution in the net tangible book value per share of the common stock you purchase, and may experience additional dilution in the future.

Because the effective price per share of common stock included in the units or issuable upon exercise of the warrants or pre-funded warrants being offered may be higher than the net tangible book value per share of our common stock, you may experience dilution to the extent of the difference between the effective offering price per share of common stock you pay in this offering and the net tangible book value per share of our common stock immediately after this offering. Assuming the sale of 45,454,545 units at a public offering price of $0.22 per unit and our net tangible book value as of June 30, 2023, and assuming no sale of any pre-funded units in this offering, no exercise of any of the common warrants being offered in this offering, and after deducting the placement agent fees and estimated offering expenses payable by us, you will incur immediate dilution in as adjusted net tangible book value of approximately $0.01 per share. As a result of the dilution to investors purchasing securities in this offering, investors may receive less than the purchase price paid in this offering, if anything, in the event of the liquidation of our company. See the section entitled " Dilution " below for a more detailed discussion of the dilution you will incur if you participate in this offering.

We have broad discretion in the use of the net proceeds we receive from this offering and may not use them effectively.

Our management will have broad discretion in the application of the net proceeds we receive in this offering, including for any of the purposes described in the section entitled " Use of Proceeds ," and you will not have the opportunity as part of your investment decision to assess whether our management is using the net proceeds appropriately. Because of the number and variability of factors that will determine our use of our net proceeds from this offering, their ultimate use may vary substantially from their currently intended use. The failure by our management to apply these funds effectively could result in financial losses that could have a material adverse effect on our business and cause the price of our common stock to decline. Pending their use, we may invest our net proceeds from this offering in short-term, investment-grade, interest-bearing securities. These investments may not yield a favorable return to our stockholders.

Sales of a substantial number of shares of our common stock in the public market, including the shares offered under this prospectus, could lower our stock price and impair our ability to raise funds in new stock offerings.

If our stockholders sell substantial amounts of our common shares, the market price of our common shares could decrease. We had 1,810,443 common shares outstanding as of January 30, 2024. Under this registration statement, we are registering the resale of 436,509 common shares held by the selling stockholder, of which 388,036 are issuable upon exercise of pre-funded warrants and common warrants. Assuming all such warrants are exercised, the shares offered hereunder represent approximately 20% of our outstanding common stock. In addition, we may sell additional common shares in subsequent offerings.

We cannot predict the size of future issuances of common shares or the effect, if any, that future issuances and sales of common shares, including the shares offered under this registration statement, other registration statements, shares underlying outstanding warrants issued in our public offering of Units on October 30, 2023, shares available for resale under Rule 144 under the Securities Act of 1933, as amended (the "Securities Act"), or the perception that such sales could occur, may have on the market price of our common shares or our ability to raise additional capital through the sale of equity securities. With any additional issuance of common shares, investors will suffer dilution and we may experience dilution in our earnings per share, if any.

1 unchanged paragraph

This offering may cause the trading price of our common stock to decrease.

The number of shares of common stock underlying the securities we propose to issue and ultimately will issue if this offering is completed, may result in an immediate decrease in the market price of our common stock. This decrease may continue after the completion of this offering. We cannot predict the effect, if any, that the availability of shares for future sale represented by the pre-funded warrants or common warrants issued in connection with the offering will have on the market price of our common stock from time to time.

Future sales of substantial amounts of our common stock could adversely affect the market price of our common stock.

We may choose to raise additional capital due to market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans. If additional capital is raised through the sale of equity or convertible debt securities, or perceptions that those sales could occur, the issuance of these securities could result in further dilution to investors purchasing our common stock in this offering or result in downward pressure on the price of our common stock, and our ability to raise capital in the future.

If we fail to comply with the continued minimum closing bid requirements or other Nasdaq requirements for continued listing, our common stock may be delisted and the price of our common stock and our ability to access the capital markets could be negatively impacted.

Our common stock is listed for trading on Nasdaq. We must satisfy Nasdaq's continued listing requirements, including, among other things, a minimum closing bid price requirement of $1.00 per share and minimum stockholders' agreement. On January 12, 2023, we received a letter from the Nasdaq advising us that we have failed to satisfy the $1.00 minimum bid requirement due to the fact that the closing bid price for our common stock for thirty consecutive days was less than $1.00. Although we initially had 180 days to regain compliance, on July 12, 2023, we received a letter from Nasdaq stating that, although we had not regained compliance with the minimum bid requirement, Nasdaq determined that we are eligible for an additional 180-day period, or until January 8, 2024, to regain compliance with the minimum bid requirement. A delisting of our common stock from Nasdaq could materially reduce the liquidity of our common stock and result in a corresponding material reduction in the price of our common stock. In addition, delisting could harm our ability to raise capital through alternative financing sources on terms acceptable to us, or at all, and may result in the potential loss of confidence by investors, employees and fewer business development opportunities.

We may not receive any additional funds upon the exercise of the common warrants.

Each common warrant has an exercise price of $[●] per share (equal to 100% of the public offering price of each unit sold in this offering), and may also be exercised in certain circumstances by way of a cashless exercise, meaning that the holder may not pay a cash purchase price upon exercise, but instead would receive upon such exercise the net number of shares of our common stock determined according to the formula set forth in the warrant. Accordingly, we may not receive any additional funds, or any significant additional funds, upon the exercise of the warrants.

There is no public market for the common warrants or pre-funded warrants being offered by us in this offering.

There is no established public trading market for the common warrants or the pre-funded warrants, and we do not expect a market to develop. In addition, we do not intend to apply to list the common warrants or the pre-funded warrants on any national securities exchange or other nationally recognized trading system. Without an active market, the liquidity of the common warrants and the pre-funded warrants will be limited.

The common warrants included in the units and in the pre-funded units are speculative in nature.

The common warrants represent the right to acquire shares of common stock at a fixed price. Specifically, commencing on the date of issuance, holders of the common warrants may acquire the shares of common stock issuable upon exercise of such warrants at an exercise price of $[●] per share of common stock (equal to 100% of the public offering price of each unit sold in this offering). Moreover, following this offering, the market value of the common warrants is uncertain and there can be no assurance that the market value of the common warrants will equal or exceed the public offering price. There can be no assurance that the market price of the shares of common stock will ever equal or exceed the exercise price of the common warrants, and consequently, whether it will ever be profitable for holders of common warrants to exercise the common warrants.

Except as otherwise set forth in the common warrants and pre-funded warrants, holders of the common warrants and the pre-funded warrants offered hereby will have no rights as stockholders with respect to the shares of common stock underlying the common warrants and the pre-funded warrants until such holders exercise their common warrants and pre-funded warrants and acquire our common stock.

Except as otherwise set forth in the common warrants and pre-funded warrants, until holders of the common warrants and the pre-funded warrants acquire shares of our common stock upon exercise thereof, such holders of the common warrants and the pre-funded warrants will have no rights with respect to the shares of our common stock underlying such warrants, such as voting rights. Upon exercise of the common warrants or the pre-funded warrants, as the case may be, the holder will be entitled to exercise the rights of a common stockholder only as to matters for which the record date occurs after the exercise date.

Purchasers who purchase our securities in this offering pursuant to a securities purchase agreement may have rights not available to purchasers that purchase without the benefit of a securities purchase agreement.

In addition to rights and remedies available to all purchasers in this offering under federal securities and state law, the purchasers that enter into a securities purchase agreement will also be able to bring claims for breach of contract against us. The ability to pursue a claim for breach of contract provides those investors with the means to enforce the covenants uniquely available to them under the securities purchase agreement including timely delivery of shares and indemnification for breach of contract.

Although our shares are listed on the Nasdaq Capital Market, the market for our shares has demonstrated varying levels of trading activity. The current level of trading may not be sustained in the future. The lack of an active market for our shares may impair investors' ability to sell their shares at the time they wish to sell them or at a price that they consider reasonable, may reduce the fair market value of their shares, and may impair our ability to raise capital to continue to fund operations by selling shares, and may impair our ability to acquire additional intellectual property assets by using our shares as consideration.

Use of proceeds 8 changes

We estimate that the net proceeds from this offering will be approximately $9,120,000 (assuming the sale of all units offered hereby at the assumed public offering price of $0.22 per unit, which represents the closing sale price of our common stock on the Nasdaq Capital Market on October 20, 2023, and assuming no issuance of pre-funded warrants), after deducting placement agent fees and estimated offering expenses payable by us, and assuming no sale of any pre-funded units offered hereunder. However, because this is a reasonable best efforts offering with no minimum number of securities or amount of proceeds as a condition to closing, the actual offering amount, placement agent fees and net proceeds to us are not presently determinable and may be substantially less than the maximum amounts set forth on the cover page of this prospectus, and we may not sell all or any of the securities we are offering. As a result, we may receive significantly less in net proceeds. Based on the assumed offering price set forth above, we estimate that our net proceeds from the sale of 75% or 50% of the units offered in this offering would be approximately $6,795,000 and $4,470,000, respectively, after deducting placement agent fees and estimated offering expenses payable by us.

A $0.05 increase or decrease in the assumed public offering price of $0.22 per unit would increase or decrease the net proceeds from this offering by $2,113,636, assuming that the number of units offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting placement agent fees and estimated offering expenses payable by us, and assuming no sale of any pre-funded units offered hereunder.

We currently intend to use the net proceeds of this offering as follows: (i) up to $2.2 million will be used to repay indebtedness due under a $2.2 million principal amount secured convertible note due December 22, 2023 (the "Note"), as determined by the Company; and (ii) the balance, if any, will be used for general corporate and working capital purposes and to fund ongoing operations and expansion of our business. We cannot currently allocate specific percentages of the net proceeds to us from this offering that we may use for these purposes and our management will have broad discretion in the allocation of such net proceeds.

The Note accrues interest at the rate of 10% per annum in months one through six and 12% per annum in months seven through twelve, payable monthly. The Note is secured by a lien on substantially all of our assets and properties and can be prepaid in whole or in part without penalty at any time. Proceeds were used for general working capital and corporate purposes.

If we do not realize net proceeds from this offering sufficient to repay the Note in full, unless we are able to extend the maturity date of the Note or generate sufficient positive cash flow from operations or liquidation of existing inventory to repay the Note in full and fund operations, we will need to obtain additional financing to operate. To the extent that we require such additional financing, no assurance can be given that any form of additional financing will be available on terms acceptable to us, that adequate financing will be obtained to meet our needs, or that such financing would not be dilutive to existing stockholders. See " Risk Factors ."

The selling stockholder will receive all proceeds from the sale of the shares of common stock offered hereby. We will not receive any proceeds from the sale of common stock by the selling stockholder.

We will, however, receive cash proceeds equal to the exercise price of the warrants. Accordingly, we may receive aggregate gross proceeds of up to $825,290 assuming that the common warrants are exercised in full at an exercise price of $3.15 per share and that the pre-funded warrants are exercised in full at an exercise price of $0.018 per share. We expect to use any proceeds received by us from the exercise of the warrants for working capital purposes.

We will bear all costs, expenses and fees in connection with the registration of the shares, including, without limitation, all registration and filing fees and fees and expenses of our counsel and our accountants.

Plan of distribution 68 changes

We are offering on a reasonable best efforts basis up to 45,454,545 units, based on an assumed public offering price of $0.22 per unit, which represents the closing price of our common stock on the Nasdaq Capital Marked on October 20, 2023, for gross proceeds of up to approximately $10,000,000 before deduction of placement agent fees and offering expenses. There is no minimum amount of proceeds that is a condition to closing of this offering. The actual amount of gross proceeds, if any, in this offering could vary substantially from the gross proceeds from the sale of the maximum amount of securities being offered in this prospectus.

Pursuant to a placement agency agreement, dated as of [ ● ], 2023, we have engaged Maxim Group LLC to act as our exclusive placement agent to solicit offers to purchase the securities offered by this prospectus. The placement agent is not purchasing or selling any securities, nor is it required to arrange for the purchase and sale of any specific number or dollar amount of securities, other than to use its "reasonable best efforts" to arrange for the sale of the securities by us. Therefore, we may not sell the entire amount of securities being offered. Investors purchasing securities offered hereby will have the option to execute a securities purchase agreement with us. In addition to the rights and remedies available to all investors in this offering under federal and state securities laws, the investors which enter into a securities purchase agreement will also be able to bring claims of breach of contract against us. Investors who do not enter into a securities purchase agreement shall rely solely on this prospectus in connection with the purchase of our securities in this offering. The placement agent may engage one or more subagents or selected dealers in connection with this offering.

The placement agency agreement provides that the placement agent's obligations are subject to conditions contained in the placement agency agreement.

The units will be offered at a fixed price and are expected to be issued in a single closing. There is no minimum number of units to be sold or minimum aggregate offering proceeds for this offering to close. We expect this offering to be completed not later than two business days following the commencement of this offering and we will deliver all securities issued in connection with this offering delivery versus payment ("DVP")/receipt versus payment ("RVP") upon our receipt of investor funds. Accordingly, neither we nor the placement agent has made any arrangements to place investor funds in an escrow account or trust account since the placement agent will not receive investor funds in connection with the sale of securities offered hereunder.

We will deliver the securities being issued to the investors upon receipt of investor funds for the purchase of the securities offered pursuant to this prospectus. We expect to deliver the securities being offered pursuant to this prospectus on or about [ ● ], 2023.

Placement Agent Fees, Commissions and Expenses

Upon the closing of this offering, we will pay the placement agent a cash transaction fee equal to 7% of the aggregate gross cash proceeds to us from the sale of the securities in the offering. In addition, we will reimburse the placement agent for certain of its out-of-pocket expenses incurred in connection with this offering, including the placement agent's legal fees, and actual travel and reasonable out-of-pocket expenses, in an amount not to exceed $80,000. If this offering is not completed, we have agreed to reimburse the placement agent for its actual expenses in an amount not to exceed $40,000.

The following table shows the public offering price, placement agent fees and proceeds, before expenses, to us, assuming the sale of all units in this offering and no sale of any pre-funded units in this offering.

Proceeds to us (before expenses)

We estimate that the total expenses of the offering, including registration and filing fees, printing fees and legal and accounting expenses, but excluding the placement agent fees, will be approximately $180,000, all of which are payable by us. This figure includes, among other things, the placement agent's expenses (including the legal fees, costs and expenses for the placement agent's legal counsel) that we have agreed to reimburse.

We, each of our officers and directors and executive officers and any holders of five percent or more of the outstanding shares of our common stock have agreed, subject to certain exceptions, not to offer, issue, sell, contract to sell, encumber, grant any option for the sale of or otherwise dispose of any shares of our common stock or other securities convertible into or exercisable or exchangeable for our common stock for a period of 120 days after this offering is completed without the prior written consent of the placement agent.

The placement agent may in its sole discretion and at any time without notice release some or all of the shares subject to lock-up agreements prior to the expiration of the lock-up period. When determining whether or not to release shares from the lock-up agreements, the placement agent will consider, among other factors, the security holder's reasons for requesting the release, the number of shares for which the release is being requested and market conditions at the time.

In addition, we have also agreed with the placement agent that until the six-month anniversary of the closing date of this offering, we will not effect or enter into an agreement to effect a "Variable Rate Transaction" as defined in the placement agency agreement to be entered into with each purchaser.

We have agreed to indemnify the placement agent against certain liabilities, including liabilities under the Securities Act, and to contribute to payments that the placement agent may be required to make for these liabilities.

If within nine (9) months following the closing of this offering, we complete any financing of equity, equity-linked, convertible or debt or other capital-raising activity for which Maxim is not acting as underwriter or placement agent (other than the exercise by any person or entity of any options, warrants or other convertible securities) with up to 20 of the institutional investors who were contacted, introduced or participated in the offering, then we will pay to Maxim upon the closing of such financing or receipt of such proceeds the compensation described in this Plan of Distribution, in each case only with respect to the portion of such financing received from such investors.

Right of First Refusal

Pursuant to the terms of the placement agency agreement, subject to the closing of this offering, for a period of nine (9) months after the commencement of sales of securities in this offering to the public in this offering, Maxim shall have a right of first refusal to act as lead managing underwriter and sole book runner, sole placement agent, or sole sales agent for any and all future public or private equity, equity-linked or debt (excluding commercial bank debt) offerings for which we retain the service of an underwriter, agent, advisor, finder or other person or entity in connection with such offering during such nine (9) month period for us, or any successor to us or any of our subsidiaries. We shall not offer to retain any entity or person in connection with any such offering on terms more favorable than terms on which we offer to retain Maxim. Such offer shall be made in writing in order to be effective. Maxim shall notify us within ten (10) business days of its receipt of the written offer contemplated above as to whether or not it agrees to accept such retention. If Maxim should decline such retention, we shall have no further obligations to Maxim with respect to the offering for which we have offered to retain Maxim.

The placement agent may be deemed to be an underwriter within the meaning of Section 2(a)(11) of the Securities Act, and any commissions received by it and any profit realized on the resale of the securities sold by it while acting as principal might be deemed to be underwriting discounts or commissions under the Securities Act. As an underwriter, the placement agent would be required to comply with the requirements of the Securities Act and the Securities Exchange Act of 1934, as amended (the "Exchange Act"), including, without limitation, Rule 10b-5 and Regulation M under the Exchange Act. These rules and regulations may limit the timing of purchases and sales of our securities by the placement agent acting as principal. Under these rules and regulations, the placement agent (i) may not engage in any stabilization activity in connection with our securities and (ii) may not bid for or purchase any of our securities or attempt to induce any person to purchase any of our securities, other than as permitted under the Exchange Act, until it has completed its participation in the distribution.

Determination of Offering Price and Warrant Exercise Price

The actual offering price of the units and pre-funded units we are offering, and the exercise price of the common warrants included in the units and pre-funded units that we are offering, were negotiated between us, the placement agent and the investors in the offering based on the trading of our shares of common stock prior to the offering, among other things. Other factors considered in determining the public offering price of the securities we are offering, as well as the exercise price of the common warrants that we are offering, include our history and prospects, the stage of development of our business, our business plans for the future and the extent to which they have been implemented, an assessment of our management, the general conditions of the securities markets at the time of the offering and such other factors as were deemed relevant.

We are registering 436,509 shares of our common stock for possible sale by the selling stockholder. The selling stockholder will act independently of us in making decisions with respect to the timing, manner and size of each sale. The selling stockholder may, from time to time, sell any or all of its shares of common stock on the Nasdaq Capital Market or any other stock exchange, market or trading facility on which the shares are traded or in private transactions. These sales may be at fixed or negotiated prices. The selling stockholder may use any one or more of the following methods when selling shares:

ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

block trades in which the broker-dealer will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;

purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

an exchange distribution in accordance with the rules of the Nasdaq Capital Market or any other applicable national securities exchange;

privately negotiated transactions;

through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

broker-dealers may agree with the selling stockholder to sell a specified number of such shares at a stipulated price per share;

a combination of any such methods of sale; and

any other method permitted pursuant to applicable law.

The selling stockholder may also sell shares under Rule 144 under the Securities Act, if available, rather than under this prospectus supplement and accompanying prospectus.

Broker-dealers engaged by the selling stockholder may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the selling stockholder (or, if any broker-dealer acts as agent for the purchaser of shares, from the purchaser) in amounts to be negotiated. The selling stockholder does not expect these commissions and discounts to exceed what is customary in the types of transactions involved. Any profits on the resale of shares of common stock by a broker-dealer acting as principal might be deemed to be underwriting discounts or commissions under the Securities Act. Discounts, concessions, commissions and similar selling expenses, if any, attributable to the sale of shares will be borne by the selling stockholder.

The selling stockholder may agree to indemnify any agent, dealer or broker-dealer that participates in transactions involving sales of the shares if liabilities are imposed on that person under the Securities Act. If we are notified by the selling stockholder that any arrangement has been entered into with a broker-dealer for the sale of shares of common stock, if required, we will file an amendment to this prospectus. If the selling stockholder uses this prospectus for any sale of the shares of common stock, the selling stockholder will be subject to the prospectus delivery requirements of the Securities Act.

The selling stockholder and any broker-dealer or agents participating in the distribution of the shares of common stock may be deemed to be "underwriters" within the meaning of Section 2(11) of the Securities Act in connection with such sales. In such event, any commissions paid, or any discounts or concessions allowed to, any such broker-dealer or agent and any profit on the resale of the shares purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. If the selling stockholder is an "underwriter" within the meaning of Section 2(11) of the Securities Act, it will be subject to the applicable prospectus delivery requirements of the Securities Act and may be subject to certain statutory liabilities of, including but not limited to, Sections 11, 12 and 17 of the Securities Act and Rule 10b-5 under the Exchange Act.

The selling stockholder also may transfer the shares of common stock in other circumstances, in which case the transferees or other successors in interest will be the selling beneficial owners for purposes of this prospectus and may sell the shares of common stock from time to time under this prospectus after we have filed an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act supplementing or amending the list of selling stockholders to include the transferees or other successors in interest as selling stockholders under this prospectus.

The common warrants will be issued separately from the common stock or the pre-funded warrants, as the case may be, and may be transferred separately immediately thereafter.

The common warrants will be exercisable, at the option of each holder, in whole or in part, by delivering to us a duly executed exercise notice accompanied by payment in full for the number of shares of our common stock purchased upon such exercise.

(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:

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

(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;

(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 (iv) any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(7) (A) For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b) (1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.

(B) For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus 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.

(6) (5) 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 Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

Pursuant to the requirements of the Securities Act 1933, the Registrant has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Holmdel, State of New Jersey, on October 25, 2023. January 30, 2024.
