PRELIMINARY PROSPECTUS SUBJECT TO COMPLETION DATED SEPTEMBER 11, 2026

Up to 6,165,691 Shares of Common Stock

Gaxos.ai Inc.

Pursuant to this prospectus, the selling stockholders identified herein (the "Selling Stockholders") are offering on a resale basis up to an aggregate of 6,165,691 shares (the "Shares") of common stock, par value $0.0001 per share (the "Common Stock") of Gaxos.ai Inc. (the "Company," "we," "us" or "our") comprised of (i) up to 6,015,308 shares of Common Stock issuable upon the exercise of outstanding common stock purchase warrants at an exercise price of $0.95 per share for a term of three years from the date of issuance (the "New Warrants"); and (ii) up to 150,383 shares of Common Stock issuable upon the exercise of outstanding placement agent warrants at an exercise price of $1.50 per share for a term of three years from the date of issuance (the "Placement Agent Warrants" and together with the New Warrants, the "Warrants"). The New Warrants were issued pursuant to an inducement offer letter agreement by and between us and the Selling Stockholders named therein, dated August 14, 2026 (the "Inducement Letter"). The Placement Agent Warrants were issued to H.C. Wainwright & Co., LLC, or its designees (and certain of their assignees), pursuant to its engagement as exclusive placement agent in connection with the transactions contemplated by the Inducement Letter (the "Placement Agent").

We will not receive any of the proceeds from the sale by the Selling Stockholders of the Common Stock. Upon any exercise of the Warrants by payment of cash, however, we will receive the exercise price of the Warrants, which, if exercised in cash with respect to the Shares offered hereby, would result in gross proceeds to us of approximately $5.9 million. However, we cannot predict when and in what amounts or if the Warrants will be exercised by payments of cash and it is possible that the Warrants may expire and never be exercised, in which case we would not receive any cash proceeds.

The Selling Stockholders, or their respective transferees, pledgees, donees, assignees or other successors-in-interest identified in this prospectus may offer the Shares from time to time through public or private transactions at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market price, at varying prices determined at the time of sale, or at negotiated prices. The registration of the Shares on behalf of the Selling Stockholders; however, does not necessarily mean that the Selling Stockholders will offer or sell their Shares under this registration statement or at any time in the near future. We provide more information about how the Selling Stockholders may sell their Shares in the section entitled "Plan of Distribution" on page 14. The Selling Stockholders will bear all commissions and discounts, if any, attributable to the sale or disposition of the Shares, or interests therein. We will not be paying any underwriting discounts or commissions in this offering. We will pay the expenses of registering the Shares pursuant to this prospectus.

Our Common Stock is listed on The Nasdaq Capital Market under the symbol "GXAI". On September 9, 2026, the closing price per share of our Common Stock as reported on The Nasdaq Capital Market was $0.7350 per share. We may amend or supplement this prospectus from time to time by filing amendments or supplements as required. You should read the entire prospectus and any amendments or supplements carefully before you make your investment decision.

Gaxos Gaming

Gaxos Gaming (the "Platform"), created with a vision to develop, design, acquire, and manage conventional games and to combine these games with unconventional game mechanisms, such as the ability for gamers and developers to utilize artificial intelligence to create and design in-game features, as well as to mint unique in-game features, such as skins, characters, weapons, gear, levels, and virtual lands, in the form of non-fungible tokens, or "NFTs," that allows users to have unique experiences and more control over in-game assets.

In 2023, we launched our own proprietary games that were simple and fun to play, and that offered gamers the ability to utilize AI to personalize their gaming experience as well as to mint their own affordable NFTs, with unique and exclusive features, that could be utilized across the network of games and platform that we were building. As of December 31, 2025, we had launched five games, Space Striker AI, Brawl Bots, BattleFleet AI, Jigsaw Puzzle AI and Gaxos AI Puzzle.

On June 18, 2026, we entered into and simultaneously consummated the closing of an Asset Purchase Agreement, by and among the Company and Game Foundry AI (the "Buyer") for the sale and divestiture of substantially all of our gaming assets, including our portfolio of mobile games and Gaxos Gaming Labs in exchange for the issuance of 2,200,000 shares of the Buyer's common stock, for an estimated consideration of $1,760,000.

Use of proceeds: We will not receive any proceeds from any sale of the Shares by the Selling Stockholders. We will receive proceeds in the event that any of the Warrants are exercised at the exercise prices per share for cash which would result in gross proceeds of approximately $5.9 million if all such Warrants are exercised for cash. We can give no assurances that any such Warrant will be exercised, nor can we give any assurances that we will receive any proceeds from the Selling Stockholders' sale pursuant to this prospectus. Any proceeds that we receive from the exercise of the Warrants will be used for working capital and other general corporate purposes. See "Use of Proceeds."
Risk factors:

An investment in the shares of Common Stock offered under this prospectus is highly speculative and involves substantial risk. Please carefully consider the "Risk Factors" section on page 4, other information in this prospectus and in the documents incorporated by reference herein for a discussion of risks. Additional risks and uncertainties not presently known to us or that we currently deem to be immaterial may also impair our business and operations

Nasdaq Capital Market symbol: Our common stock is listed on The Nasdaq Capital Markets under the symbol "GXAI". There is no established trading market for the Warrants and we do not expect a trading market to develop. We do not intend to list the Warrants on any securities exchange or other trading market. Without a trading market, the liquidity of the Warrants will be extremely limited.
(1) The number of shares of Common Stock to be outstanding is based on 11,052,288 shares of our Common Stock outstanding as of September 10, 2026, and excludes:
7,667,296 shares of Common Stock issuable upon the exercise of warrants outstanding as of September 10, 2026 (after giving effect to the exercise of the Existing Warrants and the issuance of the New Warrants and Placement Agent Warrants pursuant to the Inducement Letter) at a weighted average exercise price of approximately $1.39 per share;
284,084 shares of Common Stock issuable upon the exercise of stock options outstanding as of September 10, 2026 at a weighted average exercise price of $8.02 per share; and
1,000,000 shares of Common Stock reserved for future issuance under our 2022 Equity Incentive Plan.

Unless otherwise indicated, all information in this prospectus assumes no exercise of the outstanding options or warrants, described above.

RISK FACTORS

Investing in our securities involves substantial risks. Please carefully consider the risk factors described below together with the risk factors described in our most recent Annual Report on Form 10-K, any subsequent updates in our Quarterly Reports on Form 10-Q and in any other filings we make with the SEC pursuant to Section 13(a), 13(c), 14 or 15(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), incorporated by reference herein, and the matters discussed under "Disclosure Regarding Forward-Looking Statements" below, before making an investment decision. Additional risk factors may be included in any prospectus supplements relating to securities described in this prospectus. The occurrence of any of those risks could materially and adversely affect our business, prospects, financial condition, results of operations or cash flow. Other risks and uncertainties that we do not now consider to be material or of which we are not now aware may become important factors that affect us in the future and could result in a complete loss of your investment.

We will not receive any proceeds from the sale of the shares of Common Stock by the Selling Stockholders covered by this prospectus other than upon any exercise of the New Warrants or Placement Agent Warrants for cash.

We are registering the shares of Common Stock that were, or may be, issued by us to the Selling Stockholders to permit the resale of these shares of Common Stock from time to time after the date of this prospectus. We will not receive any of the proceeds from the sale by the Selling Stockholders of the shares of Common Stock. Upon any exercise of any of the New Warrants or Placement Agent Warrants for cash, the Selling Stockholders would pay us the exercise price set forth in such New Warrants or Placement Agent Warrants.

We are currently listed on The Nasdaq Capital Market. If we are unable to maintain listing of our securities on the Nasdaq Capital Market or any stock exchange, our stock price could be adversely affected and the liquidity of our stock and our ability to obtain financing could be impaired and it may be more difficult for our shareholders to sell their securities.

Although our common stock is currently listed on The Nasdaq Capital Market ("Nasdaq"), we may not be able to continue to meet the exchange's minimum listing requirements or those of any other national exchange. If we are unable to maintain listing on Nasdaq or if a liquid market for our common stock does not develop or is sustained, our common stock may remain thinly traded.

The Listing Rules of Nasdaq require listing issuers to comply with certain standards in order to remain listed on its exchange. If, for any reason, we should fail to maintain compliance with these listing standards and Nasdaq should delist our securities from trading on its exchange and we are unable to obtain listing on another national securities exchange, a reduction in some or all of the following may occur, each of which could have a material adverse effect on our shareholders:

the liquidity of our Common Stock;
the market price of our Common Stock;
our ability to obtain financing for the continuation of our operations;
the number of investors that will consider investing in our Common Stock;
the number of market makers in our Common Stock;
the availability of information concerning the trading prices and volume of our Common Stock; and
the number of broker-dealers willing to execute trades in shares of our Common Stock.

DISCLOSURE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus and the documents incorporated by reference herein contain forward-looking statements, within the meaning of Section 27A of the Securities Act of 1933, as amended, (the "Securities Act"), and Section 21E of the Securities Exchange Act of 1934, as amended, (the "Exchange Act"), about us and our industry that involve substantial risks and uncertainties.

These statements involve a number of risks and uncertainties. Words such as "may," "expects," "intends," "anticipates," "believes," "estimates," "plans," "seeks," "could," "should," "continue," "will," "potential," "projects" and similar expressions are intended to identify such forward-looking statements. Readers are cautioned that these forward-looking statements speak only as of the date on which this prospectus is filed with the Securities and Exchange Commission (the "SEC"), and, except as required by law, we do not assume any obligation to update, amend or clarify them to reflect events, new information or circumstances occurring after such date. Forward-looking statements in this prospectus and any documents incorporated by reference herein include, but are not limited to, statements about:

our business strategies;
the timing of regulatory submissions;
our ability to obtain and maintain regulatory approval of our existing product candidates and any other product candidates we may develop, and the labeling under any approval we may obtain;
risks related to market acceptance of products;
intellectual property risks;
risks associated with our reliance on third-party organizations;
our competitive position;
our industry environment;
our anticipated financial and operating results, including anticipated sources of revenues;

5

assumptions regarding the size of the available market, benefits of our products, product pricing and timing of product launches;
management's expectation with respect to future acquisitions;
statements regarding our goals, intentions, plans and expectations, including the introduction of new products and markets; and
our cash needs and financing plans.

We caution our shareholders and other readers not to place undue reliance on such statements.

Other sections of this prospectus may include additional factors that could harm our business and financial performance. Moreover, we operate in a very competitive and rapidly changing environment. New risk factors emerge from time to time, and it is not possible for our management to predict all risk factors, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ from those contained in, or implied by, any forward-looking statements.

These and other risks and assumptions are outlined under "Risk Factors" contained in this prospectus and any related free writing prospectus, and in our most recent Annual Report on Form 10-K and our most recent filed Quarterly Reports on Form 10-Q, incorporated by reference into this prospectus, as well as any amendments thereto reflected in subsequent filings with the SEC. The discussion of risks and uncertainties set forth in this prospectus or referenced in those filings is not necessarily a complete or exhaustive list of all risks facing us at any particular point in time. We operate in a highly competitive, highly regulated and rapidly changing environment, and our business is in a state of evolution. Therefore, it is likely that new risks will emerge and the nature and elements of existing risks will change. It is not possible for management to predict all such risk factors or changes therein or to assess either the impact of all such risk factors on our business or the extent to which any individual risk factor, combination of factors or new or altered factors may cause results to differ materially from those contained in any forward-looking statement. Forward-looking statements represent our estimates and assumptions only as of the date such forward-looking statements are made. You should carefully read this prospectus and any related free writing prospectus, together with the information incorporated herein or therein by reference as described under the section titled "Incorporation of Certain Information By Reference," and with the understanding that our actual future results may materially differ from what we expect.

Except as required by law, forward-looking statements speak only as of the date they are made, and we assume no obligation to update any forward-looking statements publicly, or to update the reasons why actual results could differ materially from those anticipated in any forward-looking statements, even if new information becomes available.

USE OF PROCEEDS

We will not receive any of the proceeds from the sale by the Selling Stockholders of the Common Stock. Upon any exercise of the New Warrants or Placement Agent Warrants by payment of cash, however, we will receive the exercise price of the New Warrants and Placement Agent Warrants, which, if exercised in cash with respect to all of the Shares offered hereby, would result in gross proceeds to us of approximately $5.9 million. However, we cannot predict when and in what amounts or if the New Warrants or Placement Agent Warrants will be exercised by payments of cash and it is possible that the New Warrants or Placement Agent Warrants may expire and never be exercised, in which case we would not receive any cash proceeds. We intend to use any proceeds from the Selling Stockholders' exercise of the Warrants for working capital and other general corporate purposes.

7

SELLING STOCKHOLDERS

The Common Stock being offered by the Selling Stockholders consist of shares issuable to the Selling Stockholders upon exercise of the New Warrants and Placement Agent Warrants. We are registering the Shares in order to permit the Selling Stockholders to offer the Shares for resale from time to time. Except for the ownership of the New Warrants or Placement Agent Warrants, as applicable, or as otherwise set forth in this prospectus, the Selling Stockholders have not had any material relationship with us within the past three years.

H.C. Wainwright & Co., LLC acted as our exclusive placement agent for the transactions contemplated by the Inducement Letter and for other offerings we consummated and for which it received compensation.

The table below lists the Selling Stockholders and other information regarding the beneficial ownership of the shares of Common Stock by the Selling Stockholders. The second column lists the number of shares of Common Stock beneficially owned by the Selling Stockholders, based on their ownership of the shares of our securities, as of September 10, 2026, assuming exercise of the New Warrants and Placement Agent Warrants held by the Selling Stockholders on that date, without regard to any limitations on exercise.

The third column lists the shares of Common Stock being offered by this prospectus by the Selling Stockholders.

This prospectus generally covers the resale of the maximum number of shares of Common Stock issuable upon exercise of the Warrants, determined as if the outstanding New Warrants and Placement Agent Warrants were exercised in full as of the trading day immediately preceding the date this registration statement was initially filed with the SEC, without regard to any limitations on the exercise of the New Warrants and Placement Agent Warrants. Under the terms of the New Warrants and Placement Agent Warrants, the Selling Stockholders may not exercise the Warrants to the extent such exercise would cause such Selling Stockholder, together with their affiliates and attribution parties, to beneficially own a number of shares of Common Stock which would exceed 4.99% (or, in the case of Armistice Capital Master Fund Ltd., 9.99%) of the number of shares of our Common Stock outstanding following such exercise (for purposes of the denominator, immediately after giving effect to the issuance of shares of Common Stock to be issued upon the applicable exercise of such Warrant). The fourth column assumes the sale of all of the Shares offered by the Selling Stockholders pursuant to this prospectus without regard to such limitations. The Selling Stockholders may sell all, some or none of their Shares in this offering. See "Plan of Distribution."

(1) The ability to exercise the Warrants held by the Selling Stockholder is subject to a beneficial ownership limitation that, at the time of initial issuance of the Warrants was capped at 4.99% beneficial ownership of the Company's issued and outstanding Common Stock (or, in the case of Armistice Capital Master Fund Ltd., 9.99%). This beneficial ownership limitation may be adjusted up or down, subject to providing advanced notice to the Company. Beneficial ownership as reflected in the selling stockholders table reflects the total number of shares potentially issuable underlying the Warrants and does not give effect to this beneficial ownership limitation. Accordingly, actual beneficial ownership, as calculated in accordance with Section 13(d) and Rule 13d-3 thereunder may be lower than as reflected in the table.

Warrants Registered Pursuant to this Registration Statement

New Warrants

The New Warrants are exercisable immediately and have a term of exercise of three years from the effective date of the Resale Registration Statement, at an exercise price of $0.95 per share of Common Stock, subject to adjustment. If, at any time after issuance, a registration statement covering the resale of the New Warrant Shares is not effective, the holders may exercise the New Warrants by means of a cashless exercise. We are prohibited from effecting an exercise of the New Warrants to the extent that, as a result of such exercise, the holder together with the holder's affiliates would beneficially own more than 4.99% (or, at the election of the holder, 9.99%) of the number of shares of Common Stock outstanding immediately after giving effect to the issuance of the New Warrant Shares upon exercise of the New Warrants, which beneficial ownership limitation may be increased by the holder up to, but not exceeding, 9.99%.

Placement Agent Warrants

The Placement Agent Warrants are exercisable immediately and have a term of exercise of three years from the effective date of the Resale Registration Statement, at an exercise price of $1.50 per share of Common Stock, subject to adjustment. If, at any time after issuance, a registration statement covering the resale of the Placement Agent Warrant Shares is not effective, the holders may exercise the Placement Agent Warrants by means of a cashless exercise. We are prohibited from effecting an exercise of the Placement Agent Warrants to the extent that, as a result of such exercise, the holder together with the holder's affiliates would beneficially own more than 4.99% of the number of shares of Common Stock outstanding immediately after giving effect to the issuance of the Placement Agent Warrant Shares upon exercise of the Placement Agent Warrants, which beneficial ownership limitation may be increased by the holder up to, but not exceeding, 9.99%.

Applicable Anti-Takeover Law

Set forth below is a summary of the provisions of our Articles of Incorporation and Bylaws that could have the effect of delaying or preventing a change in control of our Company. The following description is only a summary, and it is qualified by reference to the Articles of Incorporation, Bylaws and relevant provisions of the Nevada Revised Statutes.

Board of Directors Vacancies

Our Bylaws authorize only our board of directors to fill vacant directorships. In addition, the number of directors constituting our board of directors may be set only by resolution of the majority of the incumbent directors.

Special Meeting of Shareholders

Our Bylaws provide that special meetings of our shareholders may be called by our president, our board of directors or a committee of our board of directors that has been duly designated by our board of directors and whose powers and authority include the power to call such meetings.

11

Advance Notice Requirements for Shareholder Proposals and Director Nominations

Our Bylaws provide that shareholders seeking to bring business before our annual meeting of shareholders, or to nominate candidates for election as directors at our annual meeting of shareholders, must provide timely notice of their intent in writing. To be timely, a shareholder's notice must be delivered to our secretary at our principal executive offices not later than the close of business on the 90th day nor earlier than the close of business on the 120th day prior to the first anniversary of the preceding year's annual meeting; provided, however, that in the event the date of the annual meeting is not within 25 days before or after such anniversary date, notice by the shareholder to be timely must be so delivered not later than the close of business on the 10th day following the day on which such notice of the date of annual meeting was mailed or public disclosure of the date of the annual meeting was made, whichever occurs first. These provisions may preclude our shareholders from bringing matters before our annual meeting of shareholders or from making nominations for directors at our annual meeting of shareholders.

Authorized but Unissued Shares

Our authorized but unissued shares of common stock and preferred stock are available for future issuance without shareholder approval and may be utilized for a variety of corporate purposes, including future public offerings to raise additional capital, corporate acquisitions and employee benefit plans. The existence of authorized but unissued and unreserved common stock and preferred stock could render more difficult or discourage an attempt to obtain control of our Company by means of a proxy contest, tender offer, merger or otherwise.

Exclusive Forum

Our Bylaws provide that unless we consent in writing to the selection of an alternative forum, the Eighth Judicial District Court of Clark County, Nevada shall be the sole and exclusive forum for state law claims with respect to: (i) any derivative action or proceeding brought in the name or right of our Company or on our behalf, (ii) any action asserting a claim for breach of any fiduciary duty owed by any director, officer, employee or agent of our Company to us or our shareholders, (iii) any action arising or asserting a claim arising pursuant to any provision of Nevada Revised Statutes Chapters 78 or 92A or any provision of our Articles of Incorporation or Bylaws or (iv) any action asserting a claim governed by the internal affairs doctrine, including, without limitation, any action to interpret, apply, enforce or determine the validity of our Articles of Incorporation or Bylaws. This exclusive forum provision would not apply to suits brought to enforce any liability or duty created by the Securities Act or the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction. To the extent that any such claims may be based upon federal law claims, Section 27 of the Exchange Act creates exclusive federal jurisdiction over all suits brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder. Furthermore, Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder. The enforceability of similar exclusive forum provisions in other corporations' bylaws has been challenged in legal proceedings, and it is possible that a court could rule that this provision in our Bylaws is inapplicable or unenforceable.

12

Anti-Takeover Effects of Nevada Law

Acquisition of Controlling Interest Statutes. Nevada's "acquisition of controlling interest" statutes contain provisions governing the acquisition of a controlling interest in certain Nevada corporations. These "control share" laws provide generally that any person that acquires a "controlling interest" in certain Nevada corporations may be denied certain voting rights, unless a majority of the disinterested shareholders of the corporation elects to restore such voting rights. These statutes provide that a person acquires a "controlling interest" whenever a person acquires shares of a subject corporation that, but for the application of these provisions of the Nevada Revised Statutes, would enable that person to exercise (1) one-fifth or more, but less than one-third, (2) one-third or more, but less than a majority or (3) a majority or more, of all of the voting power of the corporation in the election of directors. Once an acquirer crosses one of these thresholds, shares which it acquired in the transaction taking it over the threshold and within the 90 days immediately preceding the date when the acquiring person acquired or offered to acquire a controlling interest become "control shares" to which the voting restrictions described above apply. Our Articles of Incorporation and Bylaws currently contain no provisions relating to these statutes, and unless our Articles of Incorporation and Bylaws in effect on the tenth day after the acquisition of a controlling interest were to provide otherwise, these laws would apply to us if we were to (i) have 200 or more shareholders of record (at least 100 of which have addresses in the State of Nevada appearing on our stock ledger) and (ii) do business in the State of Nevada directly or through an affiliated corporation. If these laws were to apply to us, they might discourage companies or persons interested in acquiring a significant interest in or control of the Company, regardless of whether such acquisition may be in the interest of our shareholders.

Combination with Interested Shareholders Statutes. Nevada's "combinations with interested shareholders" statutes prohibit certain business "combinations" between certain Nevada corporations and any person deemed to be an "interested shareholder" for two years after such person first becomes an "interested shareholder" unless (i) the corporation's board of directors approves the combination (or the transaction by which such person becomes an "interested shareholder") in advance, or (ii) the combination is approved by the board of directors and 60% of the corporation's voting power not beneficially owned by the interested shareholder, its affiliates and associates. Furthermore, in the absence of prior approval certain restrictions may apply even after such two-year period. For purposes of these statutes, an "interested shareholder" is any person who is (x) the beneficial owner, directly or indirectly, of 10% or more of the voting power of the outstanding voting shares of the corporation, or (y) an affiliate or associate of the corporation and at any time within the two previous years was the beneficial owner, directly or indirectly, of 10% or more of the voting power of the then outstanding shares of the corporation. The definition of the term "combination" is sufficiently broad to cover most significant transactions between the corporation and an "interested shareholder". Subject to certain timing requirements set forth in the statutes, a corporation may elect not to be governed by these statutes. We have not included any such provision in our Articles of Incorporation.

The effect of these statutes may be to potentially discourage parties interested in taking control of the Company from doing so if it cannot obtain the approval of our board of directors.

Our transfer agent and registrar is West Coast Stock Transfer, Inc., whose address is 721 N. Vulcan Ave. Suite 106, Encinitas, CA 92024.

PLAN OF DISTRIBUTION

The Selling Stockholders and any of their transferees, pledgees, donees assignees and other successors-in-interest may, from time to time, sell any or all of their securities covered hereby on the principal Trading Market or any other stock exchange, market or trading facility on which the securities are traded or in private transactions. "Trading Market" means any of the following markets or exchanges on which our Common Stock is listed or quoted for trading on the date in question: the NYSE American, the Nasdaq Capital Market, the Nasdaq Global Market, the Nasdaq Global Select Market, the New York Stock Exchange, OTCQB or OTCQX (or any successors to any of the foregoing). These sales may be at fixed or negotiated prices. The Selling Stockholders may use any one or more of the following methods when selling securities:

ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;
block trades in which the broker-dealer will attempt to sell the securities as agent but may position and resell a portion of the block as principal to facilitate the transaction;
purchases by a broker-dealer as principal and resale by the broker-dealer for its account;
an exchange distribution in accordance with the rules of the applicable exchange;
privately negotiated transactions;
settlement of short sales;
in transactions through broker-dealers that agree with the Selling Stockholders to sell a specified number of such securities at a stipulated price per security;
through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;
a combination of any such methods of sale; or
any other method permitted pursuant to applicable law.

The Selling Stockholders may also sell securities under Rule 144 or any other exemption from registration under the Securities Act, if available, rather than under this prospectus.

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

14

In connection with the sale of the securities or interests therein, the Selling Stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the securities in the course of hedging the positions they assume. The Selling Stockholders may also sell securities short and deliver these securities to close out their short positions, or loan or pledge the securities to broker-dealers that in turn may sell these securities. The Selling Stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or create one or more derivative securities which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The Selling Stockholders and any broker-dealers or agents that are involved in selling the securities may be deemed to be "underwriters" within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the securities purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. Each Selling Stockholder has informed us that it does not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the securities.

We are required to pay certain fees and expenses that we incur incident to the registration of the securities. We have agreed to indemnify the Selling Stockholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.

We have agreed to keep this prospectus effective until no holder of the New Warrants owns any such Warrants or Shares. The resale securities will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the resale securities covered hereby may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the resale securities may not simultaneously engage in market making activities with respect to the Common Stock for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the Selling Stockholders will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of the Common Stock by the Selling Stockholders or any other person. We will make copies of this prospectus available to the Selling Stockholders and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).

Item 15. Indemnification of Officers and Directors

Section 78.7502(1) of the Nevada Revised Statutes provides that a corporation may indemnify any person who was or is a party, or is threatened to be made a party, to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (except in an action brought by or on behalf of the corporation) if that person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or enterprise, against expenses, including attorneys' fees, judgments, fines and amounts paid in settlement actually and reasonably incurred by that person in connection with such action, suit or proceeding, if that person acted in good faith and in a manner which that person reasonably believed to be in, or not opposed to, the best interests of the corporation, and, with respect to any criminal action or proceedings, had no reasonable cause to believe his conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction or upon a plea of nolo contendere or its equivalent, alone, does not create a presumption that the person did not act in good faith and in a manner which the person reasonably believed to be in, or not opposed to, the best interests of the corporation, and that, with respect to any criminal action or proceeding, the person had reasonable cause to believe his action was unlawful.

Section 78.7502(2) of the Nevada Revised Statutes provides that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit brought by or on behalf of the corporation to procure a judgment in its favor because the person acted in any of the capacities set forth above, against expenses, including amounts paid in settlement and attorneys' fees, actually and reasonably incurred by that person in connection with the defense or settlement of such action or suit, if the person acted in accordance with the standard set forth above, except that no indemnification may be made in respect of any claim, issue or matter as to which such person shall have been adjudged by a court of competent jurisdiction after exhaustion of all appeals therefrom to be liable to the corporation or for amounts paid in settlement to the corporation unless and only to the extent that the court in which such action or suit was brought or other court of competent jurisdiction determines that, in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses as the court deems proper.

Section 78.7502(3) of the Nevada Revised Statutes further provides that, to the extent a director or officer of a corporation has been successful on the merits or otherwise in the defense of any action, suit or proceeding referred to in subsections 1 and 2 thereof, or in the defense of any claim, issue or matter therein, that person shall be indemnified by the corporation against expenses (including attorneys' fees) actually and reasonably incurred by that person in connection therewith.

II-1

Section 78.751 of the Nevada Revised Statutes provides that unless indemnification is ordered by a court, the determination to provide indemnification must be made by the shareholders, by a majority vote of a quorum of the board of directors who were not parties to the action, suit or proceeding, or in specified circumstances by independent legal counsel in a written opinion. In addition, the articles of incorporation, bylaws or an agreement made by the corporation may provide for the payment of the expenses of a director or officer of the expenses of defending an action as incurred upon receipt of an undertaking to repay the amount if it is ultimately determined by a court of competent jurisdiction that the person is not entitled to indemnification. Section 78.751 of the Nevada Revised Statutes further provides that the indemnification provided for therein shall not be deemed exclusive of any other rights to which the indemnified party may be entitled and that the scope of indemnification shall continue as to directors, officers, employees or agents who have ceased to hold such positions, and to their heirs, executors and administrators.

Section 78.752 of the Nevada Revised Statutes provides that a corporation may purchase and maintain insurance on behalf of a director, officer, employee or agent of the corporation against any liability asserted against him or incurred by him in any such capacity or arising out of his status as such whether or not the corporation would have the authority to indemnify him against such liabilities and expenses.

Our Articles of Incorporation and Bylaws provide that the Company shall, to the fullest extent permitted by the provisions of the Nevada Revised Statutes, indemnify any and all persons whom it shall have the power to indemnify under the Nevada Revised Statutes.

We maintain a general liability insurance policy that covers certain liabilities of directors and officers of our corporation arising out of claims based on acts or omissions in their capacities as directors or officers.

In addition to the indemnification obligations required by our Articles of Incorporation and Bylaws, we have entered into indemnification agreements with each of our directors and officers that provide for the indemnification of our directors and executive officers for all reasonable expenses and liabilities incurred in connection with any action or proceeding brought or threatened to be brought against them by reason of the fact that they are or were our agents.

The above provisions may discourage shareholders from bringing a lawsuit against our directors for breach of their fiduciary duty. The provisions may also have the effect of reducing the likelihood of derivative litigation against directors and officers, even though such an action, if successful, might otherwise benefit us and our shareholders. Furthermore, a shareholder's investment may be adversely affected to the extent we pay the costs of settlement and damage awards against directors and officers pursuant to these indemnification provisions. We believe that these Articles of Incorporation provisions, Bylaw provisions, indemnification agreements and the insurance are necessary to attract and retain qualified persons as directors and officers.

At present, there is no pending litigation or proceeding involving any of our directors or officers where indemnification will be required or permitted. We are not aware of any threatened litigation or proceedings that might result in a claim for such indemnification.
