Up to 148,278,241 Shares of Common Stock

Aditxt, Inc.

Pursuant to this prospectus, the selling stockholders identified herein (the “Selling Stockholders”) are offering on a resale basis up to an aggregate of 148,278,241 shares (the “Shares”) of common stock, par value $0.001 per share (the “Common Stock”) of Aditxt, Inc. (the “Company,” “we,” “us” or “our”) comprised of (i) up to 9,383,524 shares of Common Stock issuable upon the exercise of outstanding exchange warrants at an exercise price of $0.50 per share for a term of five and one-half years from the date of issuance (the “Exchange Warrants”); (ii) up to 12,882,010 shares of Common Stock issuable upon the exercise of outstanding July warrants at an exercise price of $0.50 per share for a term of twenty-four months from the date of issuance (the “July Warrants”); (iii) up to 111,644,055 shares of Common Stock issuable upon the exercise of outstanding series C-1 warrants at an exercise price of $0.50 per share for a term of five years from the date of issuance (the “Series C-1 Warrants”); (iv) up to 7,037,661 shares of Common Stock issuable upon the exercise of outstanding Dawson James placement agent warrants at an exercise price of $0.50 per share for a term of five and one-half years from the date of issuance (the “DJ Placement Agent Warrants”); and (v) up to 7,330,991 shares of Common Stock issuable upon the exercise of outstanding H.C. Wainwright placement agent warrants at an exercise price of $0.50 per share for a term of five and one-half years from the date of issuance (the “HCW Placement Agent Warrants” and together with the Exchange Warrants, the July Warrants, the Series C-1 Warrants and the DJ Placement Agent Warrants, the “Warrants”). The Exchange Warrants were issued pursuant to an exchange agreement by and between us and Sabby Volatility Warrant Master Fund, Ltd. (the "Exchange Agreement”). The July Warrants were issued pursuant to a securities purchase agreement relating to the July Notes private placement (the "July Notes SPA"). The Series C-1 Warrants were issued pursuant to a securities purchase agreement relating to the Series C-1 Preferred Stock PIPE transaction (the "C-1 PIPE SPA"). The DJ Placement Agent Warrants and the HCW Placement Agent Warrants were issued as compensation for placement agent services in connection with the May 2024 PIPE private placement. The exercise price of the Warrants reflects the Adjustment Price (as defined below), as defined in the Warrants, as of the adjustment on April 7, 2026 (the “April 7, 2026 Adjustment Date”), as adjusted pursuant to the anti-dilution adjustment provisions contained in the Warrants.

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 $74.14 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 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 23. 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 “ADTX”. On April 2, 2026, the closing price per share of our Common Stock as reported on The Nasdaq Capital Market was $0.794 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.

Investing in our securities involves a high degree of risk. You should review carefully the risks and uncertainties described under the heading “Risk Factors” beginning on page 14 of this prospectus.

NEITHER THE SECURITIES AND EXCHANGE COMMISSION NOR ANY STATE SECURITIES COMMISSION HAS APPROVED OR DISAPPROVED OF THESE SECURITIES OR DETERMINED IF THIS PROSPECTUS IS TRUTHFUL OR COMPLETE. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

We take no responsibility for, and can provide no assurance as to the reliability of, any information other than the information in this prospectus, any amendment or supplement to this prospectus, and any free writing prospectus prepared by us or on our behalf. Neither we nor the Selling Stockholders are making an offer of these securities in any jurisdiction where the offer is not permitted. You should not assume that the information in this prospectus, any applicable prospectus supplement or any documents incorporated by reference is accurate as of any date other than the date of the applicable document.

 ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement that we filed with the SEC using a “shelf” registration process. Under this shelf registration process, we and the Selling Stockholders may, from time to time, issue, offer and sell, as applicable, any combination of the securities described in this prospectus in one or more offerings. The Selling Stockholders may use the shelf registration statement to sell up to an aggregate of 148,278,241 shares of Common Stock issuable upon exercise of the Warrants, from time to time through any means described in the section entitled “Plan of Distribution.” More specific terms of any securities that the Selling Stockholders offer and sell may be provided in a prospectus supplement that describes, among other things, the specific amounts and prices of the Common Stock being offered and the terms of the offering.

A prospectus supplement may also add, update or change information included in this prospectus. Any statement contained in this prospectus will be deemed to be modified or superseded for purposes of this prospectus to the extent that a statement contained in such prospectus supplement modifies or supersedes such statement. Any statement so modified will be deemed to constitute a part of this prospectus only as so modified, and any statement so superseded will be deemed not to constitute a part of this prospectus.

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 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 Warrants for cash, the Selling Stockholders would pay us the exercise price set forth in such 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:

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:

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 Warrants by payment of cash, however, we will receive the exercise price of the Warrants, which, if exercised in cash with respect to all of the Shares offered hereby, would result in gross proceeds to us of approximately $74.14 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. We intend to use any proceeds from the Selling Stockholders’ exercise of the Warrants for working capital and other general corporate purposes.

SELLING STOCKHOLDERS

The Common Stock being offered by the Selling Stockholders are those previously issued to the Selling Stockholders, and those issuable to the Selling Stockholders, upon exercise of the 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 shares of Common Stock, or as otherwise set forth herein the Selling Stockholders have not had any material relationship with us within the past three years.

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 April 1, 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 conversion.

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 Warrants were exercised in full as of the trading day immediately preceding the date this registration statement was initially filed with the SEC, each as of the trading day immediately preceding the applicable date of determination and without regard to any limitations on the exercise of the Warrants. Under the terms of the 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% 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.”

The following is a summary description of the material terms of our Common Stock as provided in our Amended and Restated Certificate of Incorporation (“Certificate of Incorporation”), and Amended and Restated Bylaws (“Bylaws”), copies of which are incorporated by reference as exhibits to the registration statement of which this prospectus forms a part.

It is subject to and qualified in its entirety by reference to our Amended and Restated Certificate of Incorporation, as amended (the “Certificate of Incorporation”) and our Amended and Restated Bylaws (the “Bylaws”), each of which are incorporated by reference as an exhibit to our Annual Report on Form 10-K. We encourage you to read our Certificate of Incorporation, Bylaws, and the applicable provisions of the Delaware General Corporation Law for additional information.

Our authorized capital shares consist of 1,000,000,000 shares of Common Stock, $0.001 par value per share, and 3,000,000 shares of preferred stock, $0.001 par value per share.

Voting Rights

Holders of Common Stock are entitled to one vote per share on all matters voted on by the stockholders, including the election of directors. Our Certificate of Incorporation and Bylaws do not provide for cumulative voting in the election of directors.

Dividend Rights

Holders of the Company’s Common Stock are entitled to receive dividends, if any, as may be declared from time to time by the board of directors in its discretion out of funds legally available for the payment of dividends.

Liquidation Rights

In the event of our liquidation, the holders of our Common Stock will be entitled to share ratably in any distribution of our assets after payment of all debts and other liabilities and the preferences payable to holders of shares of Preferred Stock then outstanding, if any.

Applicable Anti-Takeover Law

Set forth below is a summary of the provisions of the Certificate of Incorporation and the Bylaws that could have the effect of delaying or preventing a change in control of the Company. The following description is only a summary and it is qualified by refence to the Certificate of Incorporation, the Bylaws and relevant provisions of the Delaware General Corporation Law.

Warrants

Cashless Exercise

The Warrants provide for cashless exercise in the event a registration statement covering the resale of the shares of Common Stock issuable upon exercise of the Warrants is not effective.

Beneficial Ownership Limitation

The exercise of the Warrants is subject to a beneficial ownership limitation of 4.99% of the outstanding shares of Common Stock (adjustable to 9.99% upon 61 days’ prior written notice by the holder).

Anti-Dilution and Price Adjustments

Prior to the Stockholder Approval Date (as defined in the Warrants), no adjustment in the Exercise Price were permitted to be made so as to cause the Exercise price to be below the applicable Exercise Floor Price (as defined in the Warrants). Following stockholder approval (which was obtained at special meeting of stockholders on February 13, 2026 (the “Special Meeting”)), the exercise price of the Warrants (the “Adjustment Price”) and the number of shares issuable upon exercise are subject to customary anti-dilution and other adjustments, including:

At the Special Meeting, stockholders approved the issuance of the shares of common stock underlying the Series A-1 Convertible Preferred Stock and Series C-1 Convertible Preferred Stock. Following such approval, the floor price provisions applicable to these securities were eliminated. As a result, the conversion prices of the Series A-1 Convertible Preferred Stock and Series C-1 Convertible Preferred Stock are now subject to variable conversion price mechanisms, including adjustments that may result in conversion prices below a previously stated floor, and voluntary adjustment by the Company of the conversion price to conversion prices below a stated floor. The Company has issued shares of common stock at $0.50, therefore the Adjustment Price has been reduced to $0.50.

PLAN OF DISTRIBUTION

The Selling Stockholders and any of their pledgees, assignees and 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:

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 brokers-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.

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. The Selling Stockholders have informed us that they do 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 New Warrants or New Warrant Shares (as defined in the Letter Agreement). 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).

LEGAL MATTERS

The validity of the issuance of the securities offered hereby will be passed upon for us by Sheppard, Mullin, Richter & Hampton LLP, New York, New York. Additional legal matters may be passed upon for us or any underwriters, dealers, or agents by counsel that we will name in the applicable prospectus supplement.

PART II

INFORMATION NOT REQUIRED IN THE PROSPECTUS

Item 14. Other Expenses of Issuance and Distribution

The following table sets forth the costs and expenses, other than underwriting discounts and commissions, payable by us in connection with the offering of the securities being registered. All the amounts shown are estimates, except for the SEC registration fee.

Item 15. Indemnification of Officers and Directors

Our directors and officers are indemnified as provided by the Delaware General Corporation Law (the “DGCL”), our Certificate of Incorporation and our Bylaws.

Section 102 of the DGCL permits a corporation to eliminate the personal liability of directors of a corporation to the corporation or its stockholders for monetary damages for a breach of fiduciary duty as a director, except where the director breached his duty of loyalty, failed to act in good faith, engaged in intentional misconduct or knowingly violated a law, authorized the payment of a dividend or approved a stock repurchase in violation of Delaware corporate law or obtained an improper personal benefit. Our Certificate of Incorporation provides that no director of the Company shall be personally liable to us or our stockholders for monetary damages for any breach of fiduciary duty as a director, notwithstanding any provision of law imposing such liability, except to the extent that the DGCL prohibits the elimination or limitation of liability of directors for breaches of fiduciary duty.

Section 145 of the DGCL provides that a corporation has the power to indemnify a director, officer, employee, or agent of the corporation, or a person serving at the request of the corporation for another corporation, partnership, joint venture, trust or other enterprise in related capacities against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with an action, suit or proceeding to which he was or is a party or is threatened to be made a party to any threatened, ending or completed action, suit or proceeding by reason of such position, if such person acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and, in any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful, except that, in the case of actions brought by or in the right of the corporation, no indemnification shall be made with respect to any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or other adjudicating court determines that, despite the adjudication of liability but in view of all of the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

Our Certificate of Incorporation and Bylaws provide indemnification for our directors and officers to the fullest extent permitted by the DGCL. We will indemnify each person who was or is a party or threatened to be made a party to any threatened, pending or completed action, suit or proceeding (other than an action by or in the right of us) by reason of the fact that he or she is or was, or has agreed to become, a director or officer, or is or was serving, or has agreed to serve, at our request as a director, officer, partner, employee or trustee of, or in a similar capacity with, another corporation, partnership, joint venture, trust or other enterprise (all such persons being referred to as an “Indemnitee”), or by reason of any action alleged to have been taken or omitted in such capacity, against all expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred in connection with such action, suit or proceeding and any appeal therefrom, if such Indemnitee acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, our best interests, and, with respect to any criminal action or proceeding, he or she had no reasonable cause to believe his or her conduct was unlawful. Our Certificate of Incorporation and Bylaws provide that we will indemnify any Indemnitee who was or is a party to an action or suit by or in the right of us to procure a judgment in our favor by reason of the fact that the Indemnitee is or was, or has agreed to become, a director or officer, or is or was serving, or has agreed to serve, at our request as a director, officer, partner, employee or trustee of, or in a similar capacity with, another corporation, partnership, joint venture, trust or other enterprise, or by reason of any action alleged to have been taken or omitted in such capacity, against all expenses (including attorneys’ fees) and, to the extent permitted by law, amounts paid in settlement actually and reasonably incurred in connection with such action, suit or proceeding, and any appeal therefrom, if the Indemnitee acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, our best interests, except that no indemnification shall be made with respect to any claim, issue or matter as to which such person shall have been adjudged to be liable to us, unless a court determines that, despite such adjudication but in view of all of the circumstances, he or she is entitled to indemnification of such expenses. Notwithstanding the foregoing, to the extent that any Indemnitee has been successful, on the merits or otherwise, he or she will be indemnified by us against all expenses (including attorneys’ fees) actually and reasonably incurred in connection therewith. Expenses must be advanced to an Indemnitee under certain circumstances.

Certificate of Incorporation

Our Certificate of Incorporation provides that we shall, to the fullest extent permitted by the provisions of Delaware General Corporation Law, indemnify any and all persons whom it shall have the power to indemnify under such section.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Company pursuant to the foregoing provisions, or otherwise, we have been advised that, in the opinion of the SEC, such indemnification is against public policy as expressed in such Act and is, therefore, unenforceable.
