Preliminary Prospectus Supplement

(to Prospectus dated February 8, 2023)

Shares of Common Stock

We are offering                shares of our common stock, par value $0.0001 per share (“Common Stock”), at a public offering price of $                per share, to certain investors pursuant to this prospectus supplement and the accompanying prospectus.

Our Common Stock is traded on The Nasdaq Capital Market tier of The Nasdaq Stock Market, LLC under the symbol “TIVC.” The last reported sale price of our Common Stock on the Nasdaq Capital Market on August 3, 2023 was $0.0577 per share.

As of August 3, 2023, the aggregate market value of our Common Stock held by our non-affiliates was $15,592,804.26, based upon 112,097,802 shares of our outstanding Common Stock held by non-affiliates at the per share price of $0.1391, the closing sale price of our Common Stock on the Nasdaq Capital Market on June 27, 2023. Pursuant to General Instruction I.B.6 of Form S-3, in no event will we sell securities in a public offering with a value exceeding more than one-third of our “public float” (i.e., the aggregate market value of our Common Stock held by our non-affiliates) in any 12 calendar-month period so long as our public float remains below $75.0 million. During the 12 calendar months prior to and including the date of this prospectus supplement (but excluding this offering), we have sold $3,837,500 of securities in reliance on General Instruction I.B.6 of Form S-3. As a result, we are eligible to offer and sell up to an aggregate of $1,360,101.42 of our securities pursuant to General Instruction I.B.6. of Form S-3.

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 in this offering. 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. There is no required minimum number of securities that must be sold as a condition to completion of this offering, and there are no arrangements to place the funds in an escrow, trust, or similar account. See “Plan of Distribution” beginning on page S-16 of this prospectus supplement for more information regarding these arrangements.

Investing in our securities involves a high degree of risk. See the information contained under “Risk Factors” on page S-7 of this prospectus supplement and in the related sections in the accompanying prospectus and in the documents incorporated herein by reference.

ABOUT THIS PROSPECTUS SUPPLEMENT

This prospectus supplement and the accompanying prospectus are part of a “shelf” registration statement on Form S-3 (File No. 333-269494) that we originally filed with the U.S. Securities and Exchange Commission (the “SEC”), on February 1, 2023 and which became effective on February 8, 2023.

This document is in two parts. The first part is this prospectus supplement which describes the specific terms of an offering of shares of our Common Stock, and also adds to and updates information contained in the accompanying prospectus and the documents incorporated by reference in this prospectus supplement and the accompanying prospectus. The second part, the accompanying prospectus, provides more general information, some of which may not apply to this offering. Generally, when we refer to this prospectus supplement, we are referring to both parts of this document combined. To the extent there is a conflict between the information contained in this prospectus supplement and the accompanying prospectus or any document incorporated by reference that we filed with the SEC before the date of this prospectus supplement, you should rely on the information in this prospectus supplement, provided that if any statement in one of these documents is inconsistent with a statement in another document having a later date, for example, a document incorporated by reference in the accompanying prospectus – the statement in the document having the later date modifies or supersedes the earlier statement.

We further note that the representations, warranties, and covenants made by us in any agreement that is filed as an exhibit to any document that is incorporated by reference herein were made solely for the benefit of the parties to such agreement, including, in some cases, for the purpose of allocating risk among the parties to such agreements, and should not be deemed to be a representation, warranty, or covenant to you. Moreover, such representations, warranties, or covenants were accurate only as of the date when made. Accordingly, such representation, warranties, and covenants should not be relied upon as accurately representing the current state of our affairs.

If you receive any information not authorized by us, we and the placement agent take no responsibility for, and can provide no assurance as to the reliability of, such information. We are not making an offer to sell the securities in any jurisdiction where the offer or sale is not permitted.

Business Overview

Tivic is a bioelectronic medicine company developing and commercializing drug-free treatments for various diseases and conditions.

ClearUP is our first commercial product, and is FDA-approved for the treatment of sinus pain and congestion. It has also been granted a CE-Mark as a medical device for the treatment of sinus pain, pressure and congestion. ClearUP is currently sold in the U.S. directly to consumers on various platforms and through reseller channels.

In 2019, we launched ClearUP in the U.S. market. ClearUP is approved by the FDA for sale in the U.S. for the two FDA-approved indications noted above and has a CE Mark, which covers a third indication (sinus pressure) and gives us commercial access to European Union Member states and certain other countries.

First Completed July 2023 Financing

On July 10, 2023, we entered into a securities purchase agreement with certain investors, which provided for the sale and issuance by the Company of up to an aggregate of 32,500,000 shares of Common Stock, at a public offering price of $0.055 per share. The offering closed on July 11, 2023. We received gross proceeds from the offering of approximately $1.8 million, before deducting placement agent fees and other estimated offering expenses payable by us.

The shares issued in the offering were offered pursuant to a final prospectus supplement, filed with the Commission on July 10, 2023, to the Company’s effective shelf registration statement on Form S-3 (File No. 333-269494), which was initially filed with the Commission on February 1, 2023 and was declared effective on February 8, 2023.

In connection with the offering, we paid Maxim, who served as the exclusive placement agent for the offering, an aggregate cash fee equal to 8.0% of the gross proceeds of the offering (amounting to $143,000) and additional $90,000 for reimbursement of certain expenses. Additionally, we issued to Maxim, as part of Maxim’s compensation, warrants to purchase up to 1,300,000 shares of Common Stock, equal to 4.0% of the aggregate number of shares of Common Stock placed in the offering, which warrants have a term of five years from the commencement of sales under the offering, are exercisable commencing six months from closing, and have an exercise price of $0.066 per share of Common Stock (equal to 120% of the offering price per share).

S-3

Pursuant to the securities purchase agreement entered into in connection with the offering, the investors agreed to vote, at a special meeting of stockholders, in favor of an amendment to our amended and restated certificate of incorporation to effect, at the discretion of our board of directors, a reverse stock split of all of our issued and outstanding shares of Common Stock at a ratio within a range to be determined by our board of directors prior to filing a proxy statement with the Commission related thereto, without further approval or authorization of our stockholders.

On July 13, 2023, we filed a preliminary proxy statement with the Commission, and on July 24, 2023, we filed a definitive proxy statement with the Commission, to approve the foregoing proposal, as well as a proposal to permit the Company to adjourn the meeting to a later date or dates, if necessary or appropriate, to approve the foregoing proposal. The record date for the special meeting of stockholders (the “Special Meeting”) was July 11, 2023, and we will hold the Special Meeting on August 11, 2023.

Second Completed July 2023 Financing

On July 14, 2023, we entered into a securities purchase agreement with certain investors, which provided for the sale and issuance by the Company of up to an aggregate of 51,250,000 shares of Common Stock, at a public offering price of $0.040 per share. The offering closed on July 19, 2023. We received gross proceeds from the offering of approximately $2.1 million, before deducting placement agent fees and other estimated offering expenses payable by us.

The shares issued in the offering were offered pursuant to a final prospectus supplement, filed with the Commission on July 17, 2023, to the Company’s effective shelf registration statement on Form S-3 (File No. 333-269494), which was initially filed with the Commission on February 1, 2023 and was declared effective on February 8, 2023.

In connection with the offering, we paid Maxim, who served as the exclusive placement agent for the offering, an aggregate cash fee equal to 8.0% of the gross proceeds of the offering (amounting to $164,000) and additional $60,000 for reimbursement of certain expenses. Additionally, we issued to Maxim, as part of Maxim’s compensation, warrants to purchase up to 2,050,000 shares of Common Stock, equal to 4.0% of the aggregate number of shares of Common Stock placed in the offering, which warrants have a term of five years from the commencement of sales under the offering, are exercisable commencing six months from closing, and have an exercise price of $0.048 per share of Common Stock (equal to 120% of the offering price per share).

Nasdaq Notice

On July 24, 2023, as anticipated, the Company received a new notification letter from the Listing Qualifications Department of Nasdaq notifying the Company that, as of July 21, 2023, the Company’s common stock had a closing bid price of $0.10 or less for ten consecutive trading days and that, consistent with Nasdaq Listing Rule 5810(c)(3)(A)(iii), the Staff has determined to delist the Company’s common stock from the Nasdaq Capital Market. The notice further provided that the Company has until July 31, 2023 to appeal the Staff’s decision.

On July 27, 2023, the Company submitted a request for a hearing before a Nasdaq Hearings Panel (“Panel”) to appeal the Staff’s delisting determination, which was granted and the hearing has been scheduled to occur on September 21, 2023. Subject to receipt of stockholder approval at the Special Meeting, the Company currently intends to implement a reverse stock split in order to regain compliance with the Nasdaq continued listing rules prior to the hearing date.

While the appeal process is pending, the suspension of trading of the Company’s common stock will be stayed and the Company’s common stock will continue to trade on the Nasdaq Capital Market until the hearing process concludes and the Panel issues a written decision. However, there are no assurances that an extension will be

S-4

granted or that a favorable decision will be obtained from the Panel. If an extension is not provided or a favorable decision is not obtained from the Panel, our Common Stock will be delisted from the Nasdaq Capital Market, which would adversely impact liquidity of our Common Stock, potentially result in even lower bid prices for our Common Stock, and make it more difficult for us to obtain financing through the sale of our Common Stock.

RISK FACTORS

Investment in our securities involves risks. Before deciding whether to invest in our securities, you should consider carefully the risk factors discussed below in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference, including those contained in the section entitled “Risk Factors” contained in our Annual Report on Form 10-K for the year ended December 31, 2022 and our Quarterly Report on Form 10-Q for the quarter ended March 31, 2023, which are incorporated herein by reference in their entirety, as well as any amendment or update to our risk factors reflected in subsequent filings with the SEC. If any of the risks or uncertainties described in our SEC filings actually occurs, our business, financial condition, results of operations or cash flow could be materially and adversely affected. This could cause the trading price of our Common Stock to decline, resulting in a loss of all or part of your investment. The risks and uncertainties we have described are not the only ones facing our company. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our business operations.

Risks Related to the Company

We have a history of net losses and we may not achieve or maintain profitability in the future.

We have incurred net losses since inception. For the three months ended March 31, 2023, we incurred net losses of $2.1 million and for the years ended December 31, 2022 and 2021, we incurred net losses of $10.1 million and $8.5 million, respectively. At March 31, 2023 and December 31, 2022, we had working capital of approximately $4.9 million and $3.4 million, respectively, and an accumulated deficit of $31.8 million and $29.6 million, respectively. During the three months ended March 31, 2023, we used $2.4 million of cash for operating activities. During the years ended December 31, 2022 and 2021, we used $8.9 million and $5.6 million of cash, respectively, for operating activities. The net losses we incur may fluctuate significantly from quarter to quarter and may increase as a result of macroeconomic factors. Additionally, future costs relating to product development and operating activities may be significantly higher than our historical costs.

Management expects to incur substantial additional operating losses for at least the next two years to expand our markets, complete development of new products, obtain regulatory approvals, launch and commercialize our products and continue research and development programs.

Our future capital requirements will depend upon many factors, including, without limitation, progress with developing, manufacturing and marketing our technologies; the time and costs involved in preparing, filing, prosecuting, maintaining and enforcing patent claims and other proprietary rights; our ability to successfully execute our acquisition strategy, including the closing of potential acquisitions and integrating new business into our own; our ability to establish collaborative arrangements; marketing activities; and competing technological and market developments. Our ability to generate revenue and achieve profitability requires us to successfully market and secure purchase orders for our products and services from customers currently identified in our sales pipeline as well as new customers. We will also be required to efficiently manufacture and deliver equipment on those purchase orders. These activities, including our planned research and development efforts, will require significant uses of working capital. There can be no assurance that we will generate revenue and cash as expected in our current business plan. We will need to raise additional capital to continue operating our business and fund our planned operations, including to execute on our acquisition strategy, research and development, clinical trials and, if regulatory approval is obtained, commercialization of future product candidates. We may seek additional funds through equity or debt offerings and/or borrowings under notes payable, lines of credit or other sources. We do not know whether additional financing will be available on commercially acceptable terms, or at all, when needed. If adequate funds are not available or are not available on commercially acceptable terms, our ability to fund our operations, support the growth of our business or otherwise respond to competitive pressures could be significantly delayed or limited, which could materially and adversely affect our business, financial conditions, or results of operations.

Our long-term success is dependent upon our ability to successfully develop, commercialize and market our products, earn revenue, obtain additional capital when needed and, ultimately, to achieve profitable operations.

S-7

We will need to generate significant additional revenue to achieve profitability. Future products may require substantially higher levels of investment than initial products, including investments in research, development, regulatory and/or marketing and sales. It is possible that we will not achieve profitability or that, even if we do achieve profitability, we may not maintain or increase profitability in the future. Our failure to achieve or maintain profitability could negatively impact the value of our Common Stock.

There is substantial doubt about our ability to continue as a going concern.

Because we have incurred operating losses since inception, and based on our current cash levels and burn rate, amongst other things, we believe our cash and financial resources may be insufficient to meet our anticipated needs for the twelve months, which raises substantial doubt about our ability to continue as a going concern within one year from the issuance date of the financial statements incorporated by reference into this prospectus supplement. And the accompanying prospectus. These losses are expected to continue for at least a period of time. The financial statements incorporated by reference into this prospectus supplement and the accompanying prospectus have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The financial statements do not include any adjustments relating to the recoverability and classification of asset amounts or the classification of liabilities that might be necessary should we be unable to continue as a going concern within one year after the date the financial statements are issued.

Our ability to obtain additional financing will depend on a number of factors, including, among others, the condition of the capital markets and the other risks described in these risk factors. If any one of these factors is unfavorable, we may not be able to obtain additional funding, in which case, our business could be jeopardized and we may not be able to continue our operations or pursue our strategic plans. If we are forced to scale down, limit or cease operations, our shareholders could lose all or part of their investment in our Company.

We will need additional capital to fund our operations, which, if obtainable, could dilute the ownership interest of investors.

We will need additional capital to market our products, develop additional products and fund our operations, which we may raise through the sale and issuance of equity, equity-related or convertible debt, or other securities. Our future capital requirements depend on many factors including our need to market our products, acquire or develop additional products and fund our operations. We cannot be certain that additional financing will be available to us on acceptable terms when required, or at all.

If we issue additional equity securities or securities convertible into equity securities, our existing stockholders will be subject to dilution. Additionally, sales of substantial amounts of our equity securities could have an adverse effect on the value of our equity and our ability to raise additional capital through future capital increases.

We have received a notice from Nasdaq that the Staff has determined to delist the Company’s Common Stock from the Nasdaq Capital Market, which, if completed, would materially reduce the liquidity of our Common Stock and have an adverse effect on our market price.

On January 26, 2023, we received Notice from Nasdaq that the Company is not in compliance with Nasdaq Listing Rule 5550(a)(2), as the minimum bid price of our Common Stock has been below $1.00 per share for 30 consecutive business days. The Notice had no immediate effect on the listing of our Common Stock.

On July 24, 2023, as expected, we received a new notification letter from the Listing Qualifications Department of Nasdaq notifying us that, as of July 21, 2023, our Common Stock had a closing bid price of $0.10 or less for ten consecutive trading days and that, consistent with Nasdaq Listing Rule 5810(c)(3)(A)(iii), the Staff has determined to delist our Common Stock from the Nasdaq Capital Market. The notice further provided that we

S-8

had until July 31, 2023 to appeal the Staff’s decision. We submitted a request for hearing before a Nasdaq Hearings Panel to appeal the Staff’s delisting determination, which was granted and the hearing has been scheduled to occur on September 21, 2023.

Although our Common Stock will continue to trade on the Nasdaq Capital Market under the symbol “TIVC” while the appeal process is pending, if we are unable to obtain an extension from Nasdaq to regain compliance with the minimum bid price requirement, our Common Stock will be delisted. No assurances can be provided that an extension will be granted or that a favorable decision will be obtained from the Panel at the hearing.

We currently intend to effect a reverse stock split of our outstanding Common Stock, subject to receipt of stockholder approval at the Special Meeting, to regain compliance with the minimum bid price requirement prior to the hearing date. As discussed elsewhere in this prospectus supplement, we intend to hold the Special Meeting on August 11, 2023 to approve a proposal to authorize us to approve an amendment to our Charter to implement a reverse stock split, as well as an adjournment proposal. There can be no guarantee that we will receive sufficient votes in favor of the proposal at the Special Meeting. If we do not receive sufficient votes in favor of the proposal, we will consider other alternatives for regaining compliance with the minimum bid price requirement.

To the extent that we are unable to resolve the listing deficiency and receive an extension from Nasdaq to regain compliance with the minimum bid price requirement, our Common Stock will be delisted from Nasdaq, which would adversely impact liquidity of our Common Stock, potentially result in even lower bid prices for our Common Stock, and make it more difficult for us to obtain financing through the sale of our Common Stock.

If we implement a reverse stock split to regain compliance with the Nasdaq continued listing requirements, such reverse stock split could have a materially adverse effect on our business.

As noted above, subject to receipt of stockholder approval to do so, we expect that we will implement a reverse stock split in order to regain compliance with Nasdaq Listing Rule 5550(a)(2). There are a number of risks associated with implementing a reverse stock split, including, without limitation:

• The market price per share of our Common Stock post-reverse stock split may not remain in excess of the $1.00 minimum bid price per share, as required by Nasdaq, or we may fail to meet the other requirements for continued listing on Nasdaq, including the minimum value of listed securities, resulting in the delisting of our Common Stock from the Nasdaq Capital Market;

• the reverse stock split may not result in a price per share that will successfully attract certain types of investors, and such resulting share price may not satisfy the investing guidelines of institutional investors or investment funds;

• the trading liquidity of the shares of our Common Stock may not improve, or may decline, as a result of the reverse stock split and there can be no assurance that the reverse stock split, if completed, would result in the intended benefits; and

• a reverse stock split could be viewed negatively by the market and other factors, which may adversely affect the market price of our Common Stock.

There can be no assurances that implementation of a reverse stock split would allow us to prevent the delisting of our Common Stock from the Nasdaq Capital Market, and it could have a materially adverse effect on our business.

Risks Related to This Offering

Resales of our shares of Common Stock in the public market by our shareholders as a result of this offering may cause the market price of our shares of Common Stock to fall.

We are registering                shares of Common Stock offered under this prospectus supplement. Sales of substantial amounts of our shares of Common Stock in the public market, or the perception that such sales might occur, could adversely affect the market price of our shares of Common Stock. The issuance of new shares of Common Stock could result in resales of our shares of Common Stock by our current stockholders concerned about the potential ownership dilution of their holdings. Furthermore, in the future, we may issue additional shares of Common Stock or other equity or debt securities exercisable or convertible into shares of Common Stock. Any such issuance could result in substantial dilution to our existing stockholders and could cause our stock price to decline.

This offering may cause the trading price of our shares of Common Stock to decrease.

The price per share, together with the number of shares of Common Stock being offered hereby, may result in an immediate decrease in the market price of our shares. This decrease may continue after the completion of this offering.

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

In order to raise additional capital, we may in the future offer additional shares of Common Stock or other securities convertible into or exchangeable for our shares of Common Stock that could result in further dilution to investors purchasing our securities in this offering or result in downward pressure on the price of our shares of Common Stock. We may sell shares of Common Stock or other securities in any other offering at prices that are higher or lower than the prices paid by investors in this offering, and investors purchasing shares or other securities in the future could have rights superior to existing shareholders.

Our management will have broad discretion over the use of the net proceeds from this offering, you may not agree with how we use the proceeds, and the proceeds may not be invested successfully.

We have not designated any portion of the net proceeds from this offering to be used for any particular purpose. Accordingly, our management will have broad discretion as to the use of the net proceeds from this offering and could use them for purposes other than those contemplated at the time of commencement of this offering. Accordingly, you will be relying on the judgment of our management with regard to the use of these net proceeds, and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used appropriately. It is possible that, pending their use, we may invest the net proceeds in a way that does not yield a favorable, or any, return for our company. Our management’s judgment may not result in positive returns on your investment and you will not have the opportunity to evaluate the economic, financial or other information upon which our management bases its decisions.

We will need to raise additional funding to fund our working capital needs or consummate potential future acquisitions. Additional financing may not be available on acceptable terms, or at all. Failure to obtain additional capital may force us to limit or terminate our operations.

Even if we sell all shares of Common Stock offered hereby, the expected net proceeds of this offering will not be sufficient for us to fund the working capital needs of our business or potential strategic acquisitions we may pursue in the future. We may continue to seek funds through equity or debt financings, collaborative or other arrangements with corporate sources, or through other sources of financing. Additional funding may not be available to us on acceptable terms, or at all. Any failure to raise capital as and when needed could have a negative impact on our financial condition and on our ability to pursue our business plans and strategies. If we are unable to raise sufficient capital when needed, we will be unable to fund our operations and may be required

S-10

to evaluate further alternatives, which could include dissolving and liquidating our assets or seeking protection under the bankruptcy laws. A determination to file for bankruptcy could occur at a time that is earlier than when we would otherwise exhaust our cash resources.

FORWARD-LOOKING STATEMENTS

This prospectus supplement, the accompanying prospectus and the documents incorporated by reference contain “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements involve a number of risks and uncertainties. We caution readers that any forward-looking statement is not a guarantee of future performance and that actual results could differ materially from those contained in the forward-looking statement. These statements are based on current expectations of future events. Such statements include, but are not limited to, statements about future financial and operating results, plans, objectives, expectations and intentions, costs and expenses, interest rates, outcome of contingencies, financial condition, results of operations, liquidity, cost savings, objectives of management, business strategies, debt financing, clinical trial timing and plans, the achievement of clinical and commercial milestones, the advancement of our technologies and our product candidates, and other statements that are not historical facts. You can find many of these statements by looking for words like “believes,” “expects,” “anticipates,” “estimates,” “may,” “might,” “should,” “will,” “could,” “plan,” “intend,” “project,” “seek” or similar expressions in this prospectus or in documents incorporated by reference into this prospectus. We intend that such forward-looking statements be subject to the safe harbors created thereby.

These forward-looking statements are based on the current beliefs and expectations of our management and are subject to significant risks and uncertainties. If underlying assumptions prove inaccurate or unknown risks or uncertainties materialize, actual results may differ materially from current expectations and projections. Factors that might cause such a difference include those discussed in the heading “Risk Factors,” included in our most recent Annual Report on Form 10-K, as revised or supplemented by our subsequent Quarterly Reports on Form 10-Q or our Current Reports on Form 8-K that we have filed with the SEC, as well as those discussed in this prospectus supplement, the accompanying prospectus and in the documents incorporated by reference. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this prospectus supplement or, in the case of documents referred to or incorporated by reference, the date of those documents.

All subsequent written or oral forward-looking statements attributable to us or any person acting on our behalf are expressly qualified in their entirety by the cautionary statements contained or referred to in this section. Our forward-looking statements do not reflect the potential impact of any future acquisitions, mergers, dispositions, joint ventures or investments we may make. No forward-looking statement is a guarantee of future performance. We do not undertake any obligation to release publicly any revisions to these forward-looking statements to reflect events or circumstances after the date of this prospectus or to reflect the occurrence of unanticipated events, except as may be required under applicable U.S. securities law. If we do update one or more forward-looking statements, no inference should be drawn that we will make additional updates with respect to those or other forward-looking statements.

You should read this prospectus supplement, the accompanying prospectus and the documents that we reference and incorporate by reference in this prospectus supplement and the accompanying prospectus and have filed as exhibits to the registration statement, of which this prospectus is a part, completely and with the understanding that our actual future results may be materially different from what we expect.

USE OF PROCEEDS

We estimate that the net proceeds from this offering will be approximately $                 , after deducting the placement agent fees and estimated offering expenses payable by us. We currently intend to use the net proceeds from this offering as working capital for general corporate purposes. We have not determined the amount of net proceeds to be used specifically for any of such purposes.

Our expected use of net proceeds from this offering and our existing cash and cash equivalents represents our intentions based upon our current plans and business conditions, which could change in the future as our plans and business conditions evolve. As a result, we cannot predict with any certainty our use of the net proceeds from this offering. Our management will retain broad discretion over the allocation of the net proceeds from this offering. Accordingly, we will have discretion in the application of the net proceeds, and investors will be relying on our judgment regarding the application of the proceeds of this offering.

Pending our use of the net proceeds from this offering, we intend to invest the net proceeds in a variety of capital preservation investments, including short-term, investment-grade, interest-bearing instruments and U.S. government securities.

PLAN OF DISTRIBUTION

We are offering up to shares of common stock for gross proceeds of up to $                before deduction of placement agent commissions and offering expenses, in a best-efforts offering.

Pursuant to a placement agency agreement, dated as of August     , 2023, we have engaged Maxim Group LLC to act as our exclusive placement agent (“Maxim” or the “placement agent”) to solicit offers to purchase the securities offered by this prospectus supplement. 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. There is no minimum amount of proceeds that is a condition to closing of this offering. We will enter into a securities purchase agreement directly with the investors, at the investor’s option, who purchase our securities in this offering. Investors who do not enter into a securities purchase agreement shall rely solely on this prospectus supplement 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.

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 supplement. We expect to deliver the securities being offered pursuant to this prospectus on or about August     , 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 8.0% of the aggregate gross cash proceeds to us from the sale of the securities in the offering. Pursuant to the placement agency agreement, we will agree to reimburse the placement agent for certain accountable expenses of the placement agent payable by us, in an aggregate amount not to exceed $90,000. The placement agency agreement, however, will provide that in the event this offering is terminated, the placement agent will only be entitled to the reimbursement of accountable expenses actually incurred in accordance with Financial Industry Regulatory Authority, Inc. (“FINRA”) Rule 5110(g)(5)(A).

The following table shows the public offering price, placement agent fees and proceeds, before expenses, to us.

	Per Share of Common Stock	Total
Public offering price	$	$
Placement agent fees (8.0%)	$	$
Proceeds, before expenses, to us	$	$

We estimate that the total expenses of the offering, including registration, filing and listing fees, printing fees and legal and accounting expenses, but excluding the placement agent commission, will be approximately $                , all of which are payable by us. This figure does not include, among other things, the placement agent’s fees and expenses (including the legal fees, costs and expenses for the placement agent’s legal counsel) up to $90,000.

Placement Agent Warrants

We have agreed to issue to the placement agent warrants (“Placement Agent Warrants”) to purchase up to                 shares of Common Stock (which represents 4.0% of the aggregate number of shares issued in this offering) with an exercise price of $                 per share (representing 120% of the public offering price per share) exercisable commencing six (6) months after the closing of this offering for five (5) years from the date of the commencement of sales in this offering. Pursuant to FINRA Rule 5110(e), the Placement Agent Warrants and

S-16

any shares issued upon exercise of the Placement Agent Warrants shall not be sold, transferred, assigned, pledged or hypothecated, or be the subject of any hedging, short sale, derivative, put or call transaction that would result in the effective economic disposition of the securities by any person for a period of 180 days from the date of commencement of sales in this offering, except for the transfer of any security as permitted by FINRA Rule 5110(e)(2). The Placement Agent Warrants will provide for cashless exercise and will contain provisions for one demand registration of the sale of the underlying shares at the Company’s expense and “piggyback” registration rights for a period of five (5) years from the commencement of sales in the offering. The Placement Agent Warrants will provide for anti-dilution protection as permitted by FINRA Rule 5110(g).

Right of First Refusal

We have agreed that upon the closing of this offering, for a period of six (6) months from such closing we will grant the Maxim the right of first refusal to act as sole managing underwriter and book runner and/or placement agent for any and all future public or private equity, equity-linked or debt offerings of the Company or any successor to or any subsidiary of the Company during such six (6) month period.

Lock-Up Agreements

Subject to certain limited exceptions, we have agreed for a period of 30 days after the closing date not to (i) issue, enter into any agreement to issue or announce the issuance or proposed issuance of any shares of our Common Stock or other securities convertible into or exercisable or exchangeable for shares of our Common Stock or (ii) file any registration statement or amendment or supplement thereto, other than this prospectus or filing a registration statement on Form S-8 in connection with any employee benefit plan, in each case without prior written consent of the placement agent. Each of our officers and directors have agreed, for a period of 30 days after the closing of this offering, subject to certain exceptions, not to offer, 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 shares of our Common Stock 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.

Indemnification

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.

Regulation M

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 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.

S-17

PROSPECTUS SUMMARY

This summary does not contain all the information that you should consider before investing in our securities. You should read the entire prospectus and the information incorporated by reference in this prospectus carefully, including “Risk Factors” and the financial data and related notes and other information incorporated by reference, before making an investment decision.

Business Overview

We are a health technology company focused on non-invasive bioelectronic medicine. Our platform-based technology activates the body’s own healing mechanisms and can be programmed to treat various disease conditions. Our products provide a natural alternative to the standard synthetic chemical methods dominated by the pharmaceutical industry.

Bioelectronic medicine treats disease and conditions by modulating the electrical signals carried along various nerve pathways. The field grew out of the neuromodulation industry and relied, historically, on implantable devices (e.g., pacemakers, spinal implants, deep brain stimulators). IDTechEx has identified several fast-growing areas in the bioelectronic medicine field, including peripheral nerve stimulation, which it has indicated is forecasted to grow at a 35% compound annual growth rate (“CAGR”) from 2019 through 2029.

ClearUP^® is our first commercial product and has received multiple innovation awards and high customer ratings across multiple sales platforms. It is based on a non-invasive peripheral nerve stimulation platform that combines proprietary algorithms, programmable stimulation parameters, and a patented monopolar delivery. ClearUP has U.S. FDA approval for the treatment of sinus pain and congestion and E.U. CE Mark approval for the treatment of sinus pain, pressure and congestion, which gives us commercial access in the U.S., European Union Member states and certain other countries. We currently sell directly to consumers through our own website, Amazon, and Walmart. We also sell through major and specialty online retailers, such as BestBuy and FSAStore.

This patented handheld device uses ultra-low current electrical waves to relieve sinus pain and congestion symptoms that are prevalent in nasal allergies, sinus infections, chronic sinusitis, cold and flu and other disease conditions. The global treatment markets for each of these disease areas are in the billions, currently dominated

by pharmaceuticals, and are projected to grow. According to the Mintel Group Ltd’s 2020 report, the U.S. market size for cough, cold, flu and allergy in 2022 is $11.1 billion. We also conducted a market research study (via an online survey) of 600 individuals with ongoing sinus conditions and noted 90% of the participants reported interest in treatments that reduce the use of medications.

ClearUP is a US FDA Class II and EU Class IIa medical device that has received three regulatory clearances: (US FDA 510(k) number K182025, US FDA De Novo number DEN200006 and EU CE Mark Certificate number CE 704687). We conducted two published clinical studies with leading research institutions. The first clinical study was a randomized controlled double-blind trial conducted by the Stanford University Sinus Center consisting of 71 subjects suffering from sinus pain and congestion, each of whom used either ClearUP or a sham device. The second clinical study was a 30-person study on the use of ClearUP over a period of four weeks conducted by the Allergy and Asthma Associates of Santa Clara Valley Research Center. These studies have substantially demonstrated that ClearUP is highly effective at treating sinus pain from allergic rhinitis and moderate to severe congestion with no substantive side effects.

Our non-invasive bioelectronic platform-based technology enables effective therapeutic solutions with high safety profile and broad application. We plan to grow our product offerings through internal product developments, licensing and external acquisitions. We are currently conducting a sham-controlled clinical trial in

- 2 -

concert with the Icahn School of Medicine at Mount Sinai, testing a new signal variant designed to reduce pain resulting from functional endoscopic sinus surgery. If successful, a product based on this research would require new regulatory clearances for a novel indication. Similarly, we have completed a market and technology assessment of a potential migraine indication and are developing a clinical protocol related thereto. Given our deep expertise and relationships in the field of bioelectronic medicine, we are continuously monitoring and evaluating options to add complementary product lines into our product portfolio.

Our Innovation

Our products provide a natural alternative to the standard synthetic chemical methods dominated by the pharmaceutical industry. Our market research study, which we paid to have conducted, indicates consumers are interested in non-pharmaceutical treatment alternatives. We combine proprietary algorithms, programmable stimulation parameters, and a patented monopolar delivery mechanism to modulate the nerve signals. ClearUP has proven effective in treating sinus and nasal inflammatory conditions and we are researching the clinical utility of this stimulation approach for other clinical conditions. There are numerous inflammatory conditions associated with peripheral nerve activity of the body, including:

• chronic quality-of-life conditions such as migraines (39 million U.S.), temporomandibular joint disorder (31 million U.S.), and tinnitus (50 million U.S.);

• severe, life-altering conditions such as trigeminal neuralgia (150,000 U.S., severe condition); and

• acute conditions such as ear infections (50% of children) and pain and swelling from facial and sinus surgeries (600,000 functional endoscopic surgeries annually, U.S.).

Each of these applications would involve regulation of pain and inflammation-related mediators like those seen in sinus and nasal inflammation.

Our technology platform has the potential to accelerate new product development by: (i) extending the existing device platform to other clinical areas, thereby reducing research and development time, and (ii) continuing to benefit from low-risk non-invasive device designations and regulatory pathways by the FDA, which typically result in shorter time to approval when compared with invasive devices or new drugs. While it is our intention to bring new products to market, medical device development is inherently uncertain and there is no guarantee that our research and development efforts will lead to approved products for other clinical indications.

Market Opportunity and Regulatory Clearances

In December 2021, Precedence Research noted that the burden of various chronic diseases and infections is growing and so have people’s healthcare expenditures. Consumers are increasing spending on their healthcare. The shift to an increased focus on improving lifestyle, growing geriatric population, rising disposable income, rising penetration of healthcare insurance, and improved access to healthcare facilities are major factors that drive growth of the medical electronics market. In 2018, the per capita healthcare expenditure in the U.S. was over $10,500. This number is expected to increase through at least 2030.

Grand View Research projects that the non-invasive electroceutical devices segment will witness the highest growth through 2030. This is due to technological advancements and rising investments in research and development by companies for innovative product development. Moreover, increasing healthcare awareness and popularity of electroceuticals in developing countries such as India, China, South Africa, and Argentina are expected to propel market growth.

The FDA first provided clearance of ClearUP in 2019 as a treatment for sinus pain from allergic rhinitis, a condition impacting an estimated 45 million U.S. adults.

- 3 -

In early 2021, the FDA granted our De Novo request to expand the label of ClearUP to treat moderate to severe congestion. The expanded label is not limited to any single cause of congestion, making it possible to market ClearUP for allergies, sinusitis, cold, flu or any other inflammatory condition impacting the sinus and nasal mucosa. With this clearance, the estimated available market for ClearUP expands to over 200 million U.S. adults.

Additionally, we have received a CE Mark for ClearUP that broadly covers sinus pain, pressure and congestion. The CE Mark allows us to market ClearUP in the European Union Member states and certain other countries that recognize the CE Mark.

Additional product development activities are ongoing for two product candidates: (i) npdPP, an at home-use device for treating postoperative pain after sinus surgery, and (ii) npdMI, an at home-use device for treating migraine headaches. These product candidates are still in early stages of development and will require additional studies and regulatory clearances prior to bringing them to market.

Competition

Currently, ClearUP^®, which is approved by the FDA for the treatment of sinus pain and congestion, is our only commercial product. Sinus pain and congestion are typically managed with over-the-counter pharmaceuticals and saline irrigation of the sinus and nasal cavities. Analgesic medications (e.g., ibuprofen/Advil, acetaminophen/ Tylenol, naproxen sodium/Aleve) are used to treat sinus pain. Congestion is often managed with antihistamines (e.g., loratadine/Claritin), oral (e.g., phenylephrine/Sudafed) and intranasal (e.g., oxymetazoline/Afrin) decongestants, and intranasal glucocorticoids (e.g., fluticasone propionate/Flonase).

Over the counter pharmaceuticals have historically had the greatest market share for sinus pain and congestion treatments; however, according to Mintel Group Ltd.’s 2020 report on Cough, Cold, Flu, and Allergy Remedies, and our own online survey, there is increasing interest among consumers to reduce reliance on drugs and to find non-drug solutions. Non-drug competitors for sinus pain and congestion treatment include nasal irrigation products such as Sinus Rinse and Navage Nasal Care. We believe that other companies selling non-pharmaceutical treatments, specifically nasal irrigation products, represent our closest competitors. ClearUP is a new product offering in the emerging bioelectronic medicine segment, and currently has a small market share.

Barriers to Entry

As a commercial-stage company that has invested our energy into patent protection and regulatory clearances, we believe we have built competitive advantages that include:

• Five issued U.S. patents and 18 additional international and U.S. patents pending;

• Three regulatory clearances: (US FDA 510(k) number K182025, US FDA De Novo number DEN200006 and EU CE Mark Certificate number CE 704687) for use of ClearUP to treat sinus pain, pressure and congestion; and

• Published, peer-reviewed studies in high-impact academic journals.

Obtaining FDA and other regulatory approvals is a high hurdle to entry into the market, and we expect to enhance our patent protections through continuous innovation.

Growth Strategy

Our objective is to become the leading provider of non-invasive bioelectronic treatments for chronic conditions. We plan to grow our product offerings through internal product developments, licensing and external acquisitions. In the near term, key elements of our growth strategy for ClearUP include the following:

Expanding Awareness of ClearUP. ClearUP is currently available for purchase directly from our own website and major on-line retailers, including but not limited to, Amazon, FSAStore, Walmart and BestBuy. Our market research indicates that, among our target market, 74% would expect to purchase on Amazon and 65% from the manufacturer’s website.

With the sales channels for ClearUP in place, our first growth lever is the expansion of advertising to drive increased awareness of ClearUP. Our second growth lever is the optimization of transaction efficiency and value through our ecommerce infrastructure investments. Our third growth lever is to deepen healthcare practitioner engagement.

Expanded ClearUP product line. We plan to expand our product offerings within the ClearUP brand based on the architecture used in the ClearUP product line.

Additional Research and Development. We intend to continue internal research to expand our neural stimulation technologies into additional product opportunities. In order to aid the expansion of our product portfolio, we anticipate continued investment into further clinical research for new product candidates, continued patent protection of our proprietary technologies and additional regulatory clearances if and when they become viable.

Additional product offerings through licensing or acquisition. We intend to add more product lines to our portfolio through licensing and/or acquisition opportunities.

Government Regulation

Our products are subject to extensive and rigorous regulation by the FDA and other federal, state and local authorities, as well as foreign regulatory authorities. The FDA regulates, among other things, the research, development, testing, design, manufacturing, approval, labeling, storage, recordkeeping, advertising, promotion and marketing, distribution, post approval monitoring and reporting and import and export of medical devices in the United States to assure the safety and effectiveness of medical devices for their intended use. The Federal Trade Commission (“FTC”) also regulates the advertising and labeling of our device in the United States. Further, we are subject to laws directed at preventing fraud and abuse, which subject our sales and marketing, training and other practices to government scrutiny.

Under no circumstances will any information filed under current items 2.02 or 7.01 of Form 8-K be deemed incorporated herein by reference unless such Form 8-K expressly provides to the contrary.

USE OF PROCEEDS

We will retain broad discretion over the use of the net proceeds to us from the sale of our securities under this prospectus. Unless otherwise provided in the applicable prospectus supplement, we intend to use the net proceeds from the sale of securities under this prospectus for general corporate purposes, which may include funding research and development, increasing our working capital and acquisitions or investments in businesses, products or technologies that are complementary to our own. We will set forth in the prospectus supplement our intended use for the net proceeds received from the sale of any securities. Pending the application of the net proceeds, we intend to invest the net proceeds in short-term or long-term, investment-grade, interest-bearing securities.

- 11 -

PLAN OF DISTRIBUTION

We may sell the securities covered by this prospectus to one or more underwriters for public offering and sale by them, and may also sell the securities to investors directly or through agents. We will name any underwriter or agent involved in the offer and sale of securities in the applicable prospectus supplement. We have reserved the right to sell or exchange securities directly to investors on our own behalf in jurisdictions where we are authorized to do so. We may distribute the securities from time to time in one or more transactions:

• at a fixed price or prices, which may be changed;

• at market prices prevailing at the time of sale;

• at prices related to such prevailing market prices; or

• at negotiated prices.

We may directly solicit offers to purchase the securities being offered by this prospectus. We may also designate agents to solicit offers to purchase the securities from time to time. We will name in a prospectus supplement any agent involved in the offer or sale of our securities. Unless otherwise indicated in a prospectus supplement, an agent will be acting on a best efforts basis, and a dealer will purchase securities as a principal for resale at varying prices to be determined by the dealer.

If we utilize an underwriter in the sale of the securities being offered by this prospectus, we will execute an underwriting agreement with the underwriter at the time of sale and we will provide the name of any underwriter in the prospectus supplement that the underwriter will use to make resales of the securities to the public. In connection with the sale of the securities, we, or the purchasers of securities for whom the underwriter may act as agent, may compensate the underwriter in the form of underwriting discounts or commissions. The underwriter may sell the securities to or through dealers, and those dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters or commissions from the purchasers for whom they may act as agent.

We will provide in the applicable prospectus supplement any compensation we pay to underwriters, dealers, or agents in connection with the offering of the securities, and any discounts, concessions or commissions allowed by underwriters to participating dealers. Underwriters, dealers and agents participating in the distribution of the securities may be deemed to be underwriters within the meaning of the Securities Act of 1933 (the “Securities Act”), and any discounts and commissions received by them and any profit realized by them on resale of the securities may be deemed to be underwriting discounts and commissions. We may enter into agreements to indemnify underwriters, dealers and agents against civil liabilities, including liabilities under the Securities Act, and to reimburse them for certain expenses. We may grant underwriters who participate in the distribution of our securities under this prospectus an option to purchase additional securities to cover any over-allotments in connection with the distribution.

The securities we offer under this prospectus may or may not be listed through the Nasdaq Capital Market or any other securities exchange. To facilitate the offering of securities, certain persons participating in the offering may engage in transactions that stabilize, maintain or otherwise affect the price of the securities. This may include short sales of the securities, which involves the sale by persons participating in the offering of more securities than we sold to them. In these circumstances, these persons would cover such short positions by making purchases in the open market or by exercising their option to purchase additional securities. In addition, these persons may stabilize or maintain the price of the securities by bidding for or purchasing securities in the open market or by imposing penalty bids, whereby selling concessions allowed to dealers participating in the offering may be reclaimed if securities sold by them are repurchased in connection with stabilization transactions. The effect of these transactions may be to stabilize or maintain the market price of the securities at a level above that which might otherwise prevail in the open market. These transactions may be discontinued at any time.

- 12 -

We may engage in at the market offerings into an existing trading market in accordance with Rule 415(a)(4) under the Securities Act. In addition, we may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including short sale transactions. If so, the third party may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of stock, and they may use securities received from us in settlement of those derivatives to close out any related open borrowings of stock. The third party in these sale transactions will be an underwriter and will be identified in the applicable prospectus supplement. In addition, we may otherwise loan or pledge securities to a financial institution or other third party that in turn may sell the securities short using this prospectus. The financial institution or other third party may transfer its economic short position to investors in our securities or in connection with a concurrent offering of other securities.

We will file a prospectus supplement to describe the terms of any offering of our securities covered by this prospectus. The prospectus supplement will disclose:

• the terms of the offer;

• the names of any underwriters, including any managing underwriters, as well as any dealers or agents;

• the names of any underwriters, including any managing underwriters, as well as any dealers or agents;

• the purchase price of the securities from us;

• the net proceeds to us from the sale of the securities;

• any delayed delivery arrangements;

• any underwriting discounts, commissions or other items constituting underwriters’ compensation, and any commissions paid to agents;

• in a subscription rights offering, whether we have engaged dealer-managers to facilitate the offering or subscription, including their name or names and compensation;

• any public offering price; and

• other facts material to the transaction.

We will bear all or substantially all of the costs, expenses and fees in connection with the registration of our securities under this prospectus. The underwriters, dealers and agents may engage in transactions with us, or perform services for us, in the ordinary course of business.

DESCRIPTION OF CAPITAL STOCK

General

The following is a summary of the rights of our common stock and preferred stock, certain provisions of our amended and restated certificate of incorporation, amended and restated bylaws, and of the General Corporation Law of the State of Delaware. For more detailed information, please see our amended and restated certificate of incorporation and our amended and restated bylaws, which are filed as exhibits to the registration statement of which this prospectus is a part, as well as the relevant provisions of the General Corporation Law of the State of Delaware. We reincorporated in the State of Delaware on June 7, 2021.

Our amended and restated certificate of incorporation provide for one class of common stock. In addition, our amended and restated certificate of incorporation authorizes shares of undesignated preferred stock, the rights, preferences and privileges of which may be designated from time to time by our board of directors.

Our authorized capital stock consists of 210,000,000 shares, all with a $0.0001 par value of per share, of which:

• 200,000,000 shares are designated as common stock; and

• 10,000,000 shares are designated as preferred stock.

As of January 27, 2023, there were 9,677,734 shares of our common stock outstanding and held of record by 111 stockholders.

Common Stock

Voting Rights

Holders of our common stock are entitled to one vote for each share of common stock held of record for the election of our directors and all other matters requiring stockholder action, except with respect to amendments to our Charter to alter or change the powers, preferences, rights or other terms of any outstanding preferred stock if the holders of such affected series of preferred stock are entitled to vote on such an amendment. Holders of our common stock do not have cumulative voting rights. In the case of election of directors, all matters to be voted on by our stockholders must be approved by a plurality of the votes entitled to be cast by all shares of common stock. Accordingly, the holders of a majority of the outstanding shares of common stock entitled to vote in any election of directors can elect all of the directors standing for election, if they so choose, other than any directors that holders of any preferred stock we may issue may be entitled to elect. Except as otherwise provided by our Charter, bylaws, the rules or regulations of any stock exchange applicable to the Company, or applicable law or pursuant to any regulation applicable to the Company or its securities, all other matters presented to our stockholders at a duly called or convened meeting, at which a quorum is present, shall be decided by the affirmative vote of the majority of shares present in person or represented by proxy at the meeting and entitled to vote on the subject matter.

Dividends

Dividends may be declared and paid on shares of our common stock as and when determined by our board of directors, subject to any preferential dividend or other rights of any then outstanding preferred stock and to the requirements of applicable law. Subject to preferences that may apply to any shares of preferred stock outstanding at the time, the holders of our common stock will be entitled to share equally, identically and ratably in any dividends that our board of directors may determine to issue from time to time.

Liquidation Rights

In the event of any voluntary or involuntary liquidation, dissolution or winding up of our affairs, holders of our common stock would be entitled to share ratably in our assets that are legally available for distribution to

- 14 -

stockholders after payment of our debts and other liabilities. If we have any preferred stock outstanding at such time, holders of the preferred stock may be entitled to distribution and/or liquidation preferences. In either such case, we must pay the applicable distribution to the holders of our preferred stock before we may pay distributions to the holders of our common stock.

Other Rights

Our stockholders have no preemptive, conversion or other rights to subscribe for additional shares, and there are no redemption or sinking funds provisions applicable to the common stock. The rights, preferences and privileges of the holders of our common stock will be subject to, and may be adversely affected by, the rights of the holders of shares of any series of our preferred stock that we may designate and issue in the future.

Preferred Stock

No series of preferred stock are currently designated, and there are no shares of preferred stock currently outstanding. Under the terms of our Charter, our board of directors has the authority, without further action by our stockholders, to issue up to 10,000,000 shares of preferred stock in one or more series, to establish from time to time the number of shares to be included in each such series, to fix the dividend, voting and other rights, preferences and privileges of the shares of each wholly unissued series and any qualifications, limitations or restrictions thereon, 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.

Our board of directors may authorize the issuance of preferred stock with voting or conversion rights that could adversely affect the voting power or other rights of the holders of the common stock. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions and other corporate purposes, could, among other things, have the effect of delaying, deferring or preventing a change in our control and may adversely affect the market price of the common stock and the voting and other rights of the holders of common stock. We have no current plans to issue any shares of preferred stock.

Options

As of January 27, 2023, options to purchase 1,268,850 shares of our common stock were outstanding, of which, 357,215 were vested and exercisable as of that date.

We issue our stock options at the fair market value (“FMV”) on the date of grant. The board of directors considers several factors in determining the FMV. One factor is an independent valuation of our stock. These valuations are conducted annually in compliance with IRC 409A and ASC 718. Additional factors considered by the board of directors in determining the FMV include actual sales of our shares, changes in our financial results versus the assumptions made in the valuation reports, changes in our likely liquidity scenarios versus the assumptions made in the valuation reports, and changes in our future prospects versus the assumptions made in the valuation reports.

Warrants

As of January 27, 2023, 272,680 shares of common stock issuable upon the exercise of warrants were reserved for issuance. The warrants are currently exercisable and expire either five or five and a half years, depending on the terms of such warrants, from the effective date of the issuance of said warrant. The warrants may not be sold, transferred, assigned, pledged or hypothecated during this offering.

Registration Rights

The representative’s warrants issued in connection with our initial public offering provide for registration rights upon request, in certain cases. The sole demand registration right provided will not be greater than five

- 15 -

years from the commencement of sales of the securities issued in our initial public offering in compliance with FINRA Rule 5110(g)(8)(C). The piggyback registration rights provided will not be greater than seven years from the commencement of sales of the securities issued in our initial public offering in compliance with FINRA Rule 5110(g)(8)(D). We will bear all fees and expenses attendant to registering the securities issuable on exercise of the warrants other than underwriting commissions incurred and payable by the holders.

Anti-Takeover Effects of Delaware Law and Our Charter and Bylaws

Some provisions of Delaware law, our Charter and our Bylaws contain provisions that could make the following transactions more difficult: an acquisition of us by means of a tender offer; an acquisition of us by means of a proxy contest or otherwise; or the removal of our incumbent officers and directors. It is possible that these provisions could make it more difficult to accomplish or could deter transactions that stockholders may otherwise consider to be in their best interest or in our best interests, including transactions which provide for payment of a premium over the market price for our shares.

These provisions, summarized below, are intended to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with our board of directors. We believe that the benefits of the increased protection of our potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure us outweigh the disadvantages of discouraging these proposals because negotiation of these proposals could result in an improvement of their terms.

Classified Board of Directors

Our board of directors is divided into three classes serving three-year terms, with one class being elected each year by a plurality of the votes cast by the stockholders entitled to vote on the election.

Removal of Directors

Our Bylaws provide that, subject to the rights of the holders of the shares of any series of preferred stock, no member of our board of directors may be removed from office by our stockholders except for cause.

Stockholders Not Entitled to Cumulative Voting

Our Charter does not permit stockholders to cumulate their votes in the election of directors. Accordingly, the holders of a majority of the outstanding shares of our common stock entitled to vote in any election of directors can elect all of the directors standing for election, if they choose, other than any directors that holders of our preferred stock may be entitled to elect.

Board Vacancies

Our Bylaws generally provide that only our board of directors (and not the stockholders) may fill vacancies and newly created directorships.

While the foregoing provisions of our Charter, Bylaws and Delaware law may have an anti-takeover effect, these provisions 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 our shares 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.

- 16 -

Proposals of Business and Nominations.

Our Bylaws generally regulate proposals of business and nominations for election of directors by stockholders. In general, Section 2.5 requires stockholders intending to submit proposals or nominations at a stockholders meeting to provide the Company with advance notice thereof, including information regarding the stockholder proposing the business or nomination as well as information regarding the proposed business or nominee. Sections 2.4 and 2.5 provide a time period during which business or nominations must be provided to the Company that will create a predictable window for the submission of such notices, eliminating the risk that the Company finds a meeting will be contested after printing its proxy materials for an uncontested election and providing the Company with a reasonable opportunity to respond to nominations and proposals by stockholders.

Blank Check Preferred Stock

Our Board has the right to issue preferred stock in one or more series and to determine the designations, rights, preferences of such preferred stock without stockholder approval.

Stockholder Meetings

Our Bylaws provide that a special meeting of stockholders may be called only by chairman of our board of directors, chief executive officer or president, or by a resolution adopted by a majority of our board of directors, but such not by any other person or persons (including our stockholders).

Delaware Anti-Takeover Statute

We are subject to the provisions of Section 203 of the Delaware General Corporation Law (“Section 203”) regulating corporate takeovers. In general, Section 203 prohibits a publicly-held Delaware corporation from engaging, under certain circumstances, in a business combination with an interested stockholder for a period of three years following the date the person became an interested stockholder unless:

• prior to the date of the transaction, the board of directors of the corporation approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder;

• upon completion 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 voting stock outstanding, the outstanding voting stock owned by the interested stockholder, (i) shares owned by persons who are directors and also officers and (ii) shares owned 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

• at or subsequent to the date of the transaction, the business combination is approved by the board of directors of the corporation and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least 66 2/3% of the outstanding voting stock that is not owned by the interested stockholder.

Generally, a business combination includes a merger, asset, stock sale or other transaction resulting in a financial benefit to the interested stockholder. An interested stockholder is a person who, together with affiliates and associates, owns or, within three years prior to the determination of interested stockholder status, did own 15% or more of a corporation’s outstanding voting stock. We expect the existence of Section 203 to have an anti-takeover effect with respect to transactions our Board does not approve in advance. We also anticipate that Section 203 may discourage business combinations or other attempts that might result in a premium over the market price for the shares of common stock held by our stockholders.

Choice of Forum

Our Charter and Bylaws provide that, unless we consent in writing to the selection of an alternative form, the Court of Chancery of the State of Delaware (or, in the event that the Court of Chancery does not have jurisdiction, the federal district court for the District of Delaware or other state courts of the State of Delaware) will be the sole and exclusive forum for: (i) any derivative action or proceeding brought on our behalf; (ii) any action asserting a claim of breach of fiduciary duty owed by, or other wrongdoing by, any director, officer, employee or agent of the Company to the Company or our stockholders, creditors or other constituents; (iii) any action asserting a claim against us arising pursuant to the Delaware General Corporation Law, our Charter or our Bylaws; (iv) any action to interpret, apply, enforce or determine the validity of our Charter or Bylaws; or (v) or any action asserting a claim against us that is governed by the internal affairs doctrine; provided that, the exclusive forum provision does not apply to suits brought to enforce any liability or duty created by the Securities Act, Exchange Act or any other claim for which the federal courts have exclusive jurisdiction; and provided further that, if and only if the Court of Chancery of the State of Delaware dismisses any such action for lack of subject matter jurisdiction, or the Company consents in writing to the selection of an alternative forum, such action may be brought in another state or federal court sitting in the State of Delaware. Our Charter and Bylaws also provide that the federal district courts of the United States of America will be the exclusive forum for the resolution of any complaint asserting a cause of action against us or any of our directors, officers, employees or agents and arising under the Securities Act or Exchange Act. Nothing in Charter and Bylaws preclude stockholders that assert claims under the Exchange Act from bringing such claims in state or federal court, subject to applicable law. Our Charter also provides that any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock will be deemed to have notice of and to have consented to this choice of forum provision. It is possible that a court of law could rule that the choice of forum provision contained in our Charter is inapplicable or unenforceable if it is challenged in a proceeding or otherwise.

Transfer Agent and Registrar

The transfer agent and registrar for our common stock is Equiniti Trust Company. The transfer agent and registrar’s address is 90 Park Avenue, 25^th Floor, New York, NY 10016, and its telephone number is 800-468-9716.

Exchange Listing

DESCRIPTION OF DEBT SECURITIES

We may issue debt securities in one or more series under an indenture, to be entered into between us and a third party trustee, or may be issued without the use of an indenture. If such debt securities are issued with the use of an indenture, the indenture will be subject to and governed by the United States Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”). A copy of the form of the indenture will be filed with the SEC as an exhibit to the registration statement of which this prospectus forms a part. The following description sets forth certain general terms and provisions of the debt securities and is not intended to be complete. For a more complete description, prospective investors should refer to the indenture and/or the terms of the debt securities, as applicable. If debt securities are issued without the use of an indenture, all the terms of such debt security shall be included in the form of such debt security. If debt securities are issued, whether pursuant to an indenture or without an indenture, we will describe in the applicable prospectus supplement the particular terms and provisions of any series of debt securities and a description of how the general terms and provisions described below may apply to that series of debt securities. Prospective investors should rely on information in the applicable prospectus supplement and not on the following information to the extent that the information in such prospectus supplement is different from the following information. We will file as exhibits to the registration statement of which this prospectus is a part, or will incorporate by reference from a current report on Form 8-K that we file with the SEC, any supplemental indenture describing the terms and conditions of debt securities we are offering before the issuance of such debt securities.

We may issue debt securities and incur additional indebtedness other than through the offering of debt securities pursuant to this prospectus.

If we issue debt securities pursuant to an Indenture, the following provisions shall apply unless otherwise specified in the applicable prospectus supplement with respect to such issuance of debt securities:

General

We may offer under this prospectus up to an aggregate principal amount of $100,000,000 in debt securities, or if debt securities are issued at a discount, or in a foreign currency, foreign currency units or composite currency, the principal amount as may be sold for an aggregate public offering price of up to $100,000,000. Unless otherwise specified in the applicable prospectus supplement, the debt securities will represent our direct, unsecured obligations and will rank equally with all of our other unsecured indebtedness.

We may issue the debt securities in one or more series with the same or various maturities, at par, at a premium, or at a discount. We will describe the particular terms of each series of debt securities in a prospectus supplement relating to that series, which we will file with the SEC. The prospectus supplement relating to the particular series of debt securities being offered will specify the particular amounts, prices and terms of those debt securities. These terms may include:

• the title of the series;

• the aggregate principal amount, and, if a series, the total amount authorized and the total amount outstanding;

• the issue price or prices, expressed as a percentage of the aggregate principal amount of the debt securities;

• the issue price or prices, expressed as a percentage of the aggregate principal amount of the debt securities;

• whether the debt securities are to be issuable in the form of certificated securities (as described below) or global securities (as described below);

• the portion of principal amount that will be payable upon declaration of acceleration of the maturity date if other than the principal amount of the debt securities;

• the currency of denomination;

• the designation of the currency, currencies or currency units in which payment of principal and, if applicable, premium and interest, will be made;

• if payments of principal and, if applicable, premium or interest, on the debt securities are to be made in one or more currencies or currency units other than the currency of denomination, the manner in which the exchange rate with respect to such payments will be determined;

• if amounts of principal and, if applicable, premium and interest may be determined by reference to an index based on a currency or currencies or by reference to a commodity, commodity index, stock exchange index or financial index, then the manner in which such amounts will be determined;

• the provisions, if any, relating to any collateral provided for such debt securities;

• any addition to or change in the covenants and/or the acceleration provisions described in this prospectus or in the indenture;

• any events of default, if not otherwise described below under “Events of Default”;

• the terms and conditions, if any, for conversion into or exchange for shares of our common stock or preferred stock;

• any depositaries, interest rate calculation agents, exchange rate calculation agents or other agents; and

• the terms and conditions, if any, upon which the debt securities shall be subordinated in right of payment to our other indebtedness.

We may issue discount debt securities that provide for an amount less than the stated principal amount to be due and payable upon acceleration of the maturity of such debt securities in accordance with the terms of the indenture. We may also issue debt securities in bearer form, with or without coupons. If we issue discount debt securities or debt securities in bearer form, we will describe material U.S. federal income tax considerations and other material special considerations which apply to these debt securities in the applicable prospectus supplement.

We may issue debt securities denominated in or payable in a foreign currency or currencies or a foreign currency unit or units. If we do, we will describe the restrictions, elections, and general tax considerations relating to the debt securities and the foreign currency or currencies or foreign currency unit or units in the applicable prospectus supplement.

Debt securities offered under this prospectus and any prospectus supplement may be subordinated in right of payment to certain of our outstanding senior indebtedness, including our credit facilities. In addition, we will seek the consent of the holders of any such senior indebtedness, if any, prior to issuing any debt securities under this prospectus to the extent required by the agreements evidencing such senior indebtedness, if any.

- 20 -

Registrar and Paying Agent

The debt securities may be presented for registration of transfer or for exchange at the corporate trust office of the security registrar or at any other office or agency that we maintain for those purposes. In addition, the debt securities may be presented for payment of principal, interest and any premium at the office of the paying agent or at any office or agency that we maintain for those purposes.

Conversion or Exchange Rights

Debt securities may be convertible into or exchangeable for shares of our common stock. The terms and conditions of conversion or exchange will be stated in the applicable prospectus supplement. The terms will include, among others, the following:

• the conversion or exchange price;

• the conversion or exchange period;

• provisions regarding the convertibility or exchangeability of the debt securities, including who may convert or exchange;

• events requiring adjustment to the conversion or exchange price;

• provisions affecting conversion or exchange in the event of our redemption of the debt securities; and

• any anti-dilution provisions, if applicable.

Registered Global Securities

If we decide to issue debt securities in the form of one or more global securities, then we will register the global securities in the name of the depositary for the global securities or the nominee of the depositary, and the global securities will be delivered by the trustee to the depositary for credit to the accounts of the holders of beneficial interests in the debt securities.

The prospectus supplement will describe the specific terms of the depositary arrangement for debt securities of a series that are issued in global form. None of us, the trustee, any payment agent or the security registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in a global debt security or for maintaining, supervising or reviewing any records relating to these beneficial ownership interests.

No Protection in the Event of Change of Control

The indenture does not have any covenants or other provisions providing for a put or increased interest or otherwise that would afford holders of our debt securities additional protection in the event of a recapitalization transaction, a change of control or a highly leveraged transaction. If we offer any covenants or provisions of this type with respect to any debt securities covered by this prospectus, we will describe them in the applicable prospectus supplement.

Covenants

Unless otherwise indicated in this prospectus or the applicable prospectus supplement, our debt securities will not have the benefit of any covenants that limit or restrict our business or operations, the pledging of our assets or the incurrence by us of indebtedness. We will describe in the applicable prospectus supplement any material covenants in respect of a series of debt securities.

- 21 -

Merger, Consolidation or Sale of Assets

The form of indenture provides that we will not consolidate with or merge into any other person or convey, transfer, sell or lease our properties and assets substantially as an entirety to any person, unless:

• the person formed by the consolidation or into or with which we are merged or the person to which our properties and assets are conveyed, transferred, sold or leased, is a corporation organized and existing under the laws of the U.S., any state or the District of Columbia or a corporation or comparable legal entity organized under the laws of a foreign jurisdiction and, if we are not the surviving person, the surviving person has expressly assumed all of our obligations, including the payment of the principal of and, premium, if any, and interest on the debt securities and the performance of the other covenants under the indenture; and

• immediately before and immediately after giving effect to the transaction, no event of default, and no event which, after notice or lapse of time or both, would become an event of default, has occurred and is continuing under the indenture.

Events of Default

Unless otherwise specified in the applicable prospectus supplement, the following events will be events of default under the indenture with respect to debt securities of any series:

• we fail to pay any principal or premium, if any, when it becomes due;

• we fail to pay any interest within 30 days after it becomes due;

• we fail to observe or perform any other covenant in the debt securities or the indenture for 60 days after written notice specifying the failure from the trustee or the holders of not less than 25% in aggregate principal amount of the outstanding debt securities of that series; and

• certain events involving bankruptcy, insolvency or reorganization of us or any of our significant subsidiaries.

The trustee may withhold notice to the holders of the debt securities of any series of any default, except in payment of principal of or premium, if any, or interest on the debt securities of a series, if the trustee considers it to be in the best interest of the holders of the debt securities of that series to do so.

If an event of default (other than an event of default resulting from certain events of bankruptcy, insolvency or reorganization) occurs, and is continuing, then the trustee or the holders of not less than 25% in aggregate principal amount of the outstanding debt securities of any series may accelerate the maturity of the debt securities. If this happens, the entire principal amount, plus the premium, if any, of all the outstanding debt securities of the affected series plus accrued interest to the date of acceleration will be immediately due and payable. At any time after the acceleration, but before a judgment or decree based on such acceleration is obtained by the trustee, the holders of a majority in aggregate principal amount of outstanding debt securities of such series may rescind and annul such acceleration if:

• all events of default (other than nonpayment of accelerated principal, premium or interest) have been cured or waived;

• all lawful interest on overdue interest and overdue principal has been paid; and

• the rescission would not conflict with any judgment or decree.

In addition, if the acceleration occurs at any time when we have outstanding indebtedness that is senior to the debt securities, the payment of the principal amount of outstanding debt securities may be subordinated in right of payment to the prior payment of any amounts due under the senior indebtedness, in which case the holders of debt securities will be entitled to payment under the terms prescribed in the instruments evidencing the senior indebtedness and the indenture.

If an event of default resulting from certain events of bankruptcy, insolvency or reorganization occurs, the principal, premium and interest amount with respect to all of the debt securities of any series will be due and payable immediately without any declaration or other act on the part of the trustee or the holders of the debt securities of that series.

The holders of a majority in principal amount of the outstanding debt securities of a series will have the right to waive any existing default or compliance with any provision of the indenture or the debt securities of that series and to direct the time, method and place of conducting any proceeding for any remedy available to the trustee, subject to certain limitations specified in the indenture.

No holder of any debt security of a series will have any right to institute any proceeding with respect to the indenture or for any remedy under the indenture, unless:

• the holder gives to the trustee written notice of a continuing event of default;

• the holders of at least 25% in aggregate principal amount of the outstanding debt securities of the affected series make a written request and offer reasonable indemnity to the trustee to institute a proceeding as trustee;

• the trustee fails to institute a proceeding within 60 days after such request; and

• the holders of a majority in aggregate principal amount of the outstanding debt securities of the affected series do not give the trustee a direction inconsistent with such request during such 60-day period.

These limitations do not, however, apply to a suit instituted for payment on debt securities of any series on or after the due dates expressed in the debt securities.

We will periodically deliver certificates to the trustee regarding our compliance with our obligations under the indenture.

Modification and Waiver

From time to time, we and the trustee may, without the consent of holders of the debt securities of one or more series, amend the indenture or the debt securities of one or more series, or supplement the indenture, for certain specified purposes, including:

• to provide that the surviving entity following a change of control permitted under the indenture will assume all of our obligations under the indenture and debt securities;

• to provide for certificated debt securities in addition to uncertificated debt securities;

• to comply with any requirements of the SEC under the Trust Indenture Act of 1939;

• to provide for the issuance of and establish the form and terms and conditions of debt securities of any series as permitted by the indenture;

• to cure any ambiguity, defect or inconsistency, or make any other change that does not materially and adversely affect the rights of any holder; and

• to appoint a successor trustee under the indenture with respect to one or more series.

From time to time we and the trustee may, with the consent of holders of at least a majority in principal amount of an outstanding series of debt securities, amend or supplement the indenture or the debt securities series, or waive compliance in a particular instance by us with any provision of the indenture or the debt securities. We may not, however, without the consent of each holder affected by such action, modify or

- 23 -

supplement the indenture or the debt securities or waive compliance with any provision of the indenture or the debt securities in order to:

• reduce the amount of debt securities whose holders must consent to an amendment, supplement, or waiver to the indenture or such debt security;

• reduce the rate of or change the time for payment of interest or reduce the amount of or postpone the date for payment of sinking fund or analogous obligations;

• reduce the principal of or change the stated maturity of the debt securities;

• make any debt security payable in money other than that stated in the debt security;

• change the amount or time of any payment required or reduce the premium payable upon any redemption, or change the time before which no such redemption may be made;

• waive a default in the payment of the principal of, premium, if any, or interest on the debt securities or a redemption payment;

• waive a redemption payment with respect to any debt securities or change any provision with respect to redemption of debt securities; or

• take any other action otherwise prohibited by the indenture to be taken without the consent of each holder affected by the action.

Defeasance of Debt Securities and Certain Covenants in Certain Circumstances

The indenture permits us, at any time, to elect to discharge our obligations with respect to one or more series of debt securities by following certain procedures described in the indenture. These procedures will allow us either:

• to defease and be discharged from any and all of our obligations with respect to any debt securities except for the following obligations (which discharge is referred to as “legal defeasance”):

1. to register the transfer or exchange of such debt securities;

2. to replace temporary or mutilated, destroyed, lost or stolen debt securities;

3. to compensate and indemnify the trustee; or

4. to maintain an office or agency in respect of the debt securities and to hold monies for payment in trust; or

• to be released from our obligations with respect to the debt securities under certain covenants contained in the indenture, as well as any additional covenants which may be contained in the applicable supplemental indenture (which release is referred to as “covenant defeasance”).

In order to exercise either defeasance option, we must deposit with the trustee or other qualifying trustee, in trust for that

• purpose:

• money;

• U.S. Government Obligations (as described below) or Foreign Government Obligations (as described below) that through the scheduled payment of principal and interest in accordance with their terms will provide money; or

• a combination of money and/or U.S. Government Obligations and/or Foreign Government Obligations sufficient in the written opinion of a nationally-recognized firm of independent accountants to provide money;

- 24 -

that, in each case specified above, provides a sufficient amount to pay the principal of, premium, if any, and interest, if any, on the debt securities of the series, on the scheduled due dates or on a selected date of redemption in accordance with the terms of the indenture.

In addition, defeasance may be effected only if, among other things:

• in the case of either legal or covenant defeasance, we deliver to the trustee an opinion of counsel, as specified in the indenture, stating that as a result of the defeasance neither the trust nor the trustee will be required to register as an investment company under the Investment Company Act of 1940;

• in the case of legal defeasance, we deliver to the trustee an opinion of counsel stating that we have received from, or there has been published by, the Internal Revenue Service a ruling to the effect that, or there has been a change in any applicable federal income tax law with the effect that (and the opinion shall confirm that), the holders of outstanding debt securities will not recognize income, gain or loss for U.S. federal income tax purposes solely as a result of such legal defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner, including as a result of prepayment, and at the same times as would have been the case if legal defeasance had not occurred;

• in the case of covenant defeasance, we deliver to the trustee an opinion of counsel to the effect that the holders of the outstanding debt securities will not recognize income, gain or loss for U.S. federal income tax purposes as a result of covenant defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if covenant defeasance had not occurred; and

• certain other conditions described in the indenture are satisfied.

If we fail to comply with our remaining obligations under the indenture and applicable supplemental indenture after a covenant defeasance of the indenture and applicable supplemental indenture, and the debt securities are declared due and payable because of the occurrence of any undefeased event of default, the amount of money and/or U.S. Government Obligations and/or Foreign Government Obligations on deposit with the trustee could be insufficient to pay amounts due under the debt securities of the affected series at the time of acceleration. We will, however, remain liable in respect of these payments.

The term “U.S. Government Obligations” as used in the above discussion means securities that are direct obligations of or non-callable obligations guaranteed by the United States of America for the payment of which obligation or guarantee the full faith and credit of the United States of America is pledged.

The term “Foreign Government Obligations” as used in the above discussion means, with respect to debt securities of any series that are denominated in a currency other than U.S. dollars, (1) direct obligations of the government that issued or caused to be issued such currency for the payment of which obligations its full faith and credit is pledged or (2) obligations of a person controlled or supervised by or acting as an agent or instrumentality of such government the timely payment of which is unconditionally guaranteed as a full faith and credit obligation by that government, which in either case under clauses (1) or (2), are not callable or redeemable at the option of the issuer.

Regarding the Trustee

If debt securities are issued under an indenture, we will identify the trustee with respect to any series of debt securities in the prospectus supplement relating to the applicable debt securities. You should note that if the trustee becomes a creditor of ours, the indenture and the Trust Indenture Act of 1939 limit the rights of the trustee to obtain payment of claims in certain cases, or to realize on certain property received in respect of any such claim, as security or otherwise. The trustee and its affiliates may engage in, and will be permitted to continue to engage in, other transactions with us and our affiliates. If, however, the trustee acquires any “conflicting interest” within the meaning of the Trust Indenture Act of 1939, it must eliminate such conflict or resign.

- 25 -

The holders of a majority in principal amount of the then outstanding debt securities of any series may direct the time, method and place of conducting any proceeding for exercising any remedy available to the trustee. If an event of default occurs and is continuing, the trustee, in the exercise of its rights and powers, must use the degree of care and skill of a prudent person in the conduct of his or her own affairs. Subject to that provision, the trustee will be under no obligation to exercise any of its rights or powers under the indenture at the request of any of the holders of the debt securities, unless they have offered to the trustee reasonable indemnity or security.

No Individual Liability of Incorporators, Stockholders, Officers or Directors

Each indenture provides that no incorporator and no past, present or future stockholder, officer or director of our company or any successor corporation in those capacities will have any individual liability for any of our obligations, covenants or agreements under the debt securities or such indenture.

Governing Law

The indentures, if any, and the debt securities will be governed by, and construed in accordance with, the laws of the State of California.
