Description of Securities

Exhibit 4.5

DESCRIPTION OF SECURITIES

The following summary of the material terms of the securities of CERo Therapeutics Holdings, Inc. (f/k/a Phoenix Biotech Acquisition Corp.) (“we,” “our” or “us”) is not intended to be a complete summary of the rights and preferences of such securities. You are encouraged to read the applicable provisions of Delaware law, our second amended and restated certificate of incorporation (the “Charter”), amended and restated bylaws (the “Bylaws”) and the Certificate of Designation of Preferences, Rights and Limitations of the Series A Convertible Preferred Stock (the “Certificate of Designations”) in their entirety for a complete description of the rights and preferences of the our securities.

General

We are authorized to issue up to 1,000,000,000 shares of Common Stock, $0.0001 par value per share (“Common Stock”), and 10,000,000 shares of Preferred Stock, par value $0.0001 per share (the “Preferred Stock”).

Preferred Stock

Our board of directors (the “Board”) is authorized to issue “blank check” Preferred Stock, which may be issued in one or more series upon the authorization of the Board. The Board is authorized to fix the designations, powers, preferences and the relative, participating, optional or other special rights and any qualifications, limitations and restrictions of the shares of each series of Preferred Stock. The authorized shares of the Preferred Stock are available for issuance without further action by our stockholders, unless such action is required by applicable law or the rules of any stock exchange on which the securities may be listed. If the approval of our stockholders is not required for the issuance of shares of the Preferred Stock, the Board may determine not to seek stockholder approval.

The Board will be able to, without stockholder approval, issue Preferred Stock with voting and other rights that could adversely affect the voting power and other rights of the holders of the Common Stock and could have anti-takeover effects. The ability of the Board to issue Preferred Stock without stockholder approval could have the effect of delaying, deferring or preventing a change of control of us or the removal of existing management.

Series A Convertible Preferred Stock

We designated 12,580 shares of our authorized and unissued Preferred Stock as Series A Convertible Preferred Stock (the “Series A Preferred Stock”) and established the rights, preferences and privileges of the Series A Preferred Stock pursuant to the Certificate of Designations filed with the Secretary of State of the State of Delaware, as summarized below.

General.    Each share of Series A Preferred Stock has a stated value of $1,000 per share and, when issued, the Series A Preferred Stock was fully paid and non-assessable.

Ranking.    The Series A Preferred Stock, with respect to the payment of dividends, distributions and payments upon the liquidation, dissolution and winding up of us, ranks senior to all capital stock of us unless the Required Holders (as defined in the Certificate of Designations) consent to the creation of other capital stock of us that is senior or equal in rank to the Series A Preferred Stock.

Dividends.    The holders of Series A Preferred Stock will be entitled to dividends, on an as-if converted basis, equal to and in the same form as dividends actually paid on shares of Common Stock, when and if actually paid.

Purchase Rights.    If at any time we grant, issue or sell any options, convertible securities, or rights to purchase stock, warrants, securities or other property pro rata to all or substantially all of the record holders of any class of Common Stock (the “Purchase Rights”), then each holder of Series A Preferred Stock will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which such holder could have acquired if such holder had held the number of shares of Common Stock acquirable upon complete conversion of all the Series A Preferred Stock held by such holder immediately prior to the date as of which the record holders of shares of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights at the Alternate Conversion Price (as defined in the Certificate of Designations); subject to certain limitations on beneficial ownership.

Conversion Rights

Conversion at Option of Holder.    Each holder of Series A Preferred Stock may convert all, or any part, of the outstanding Series A Preferred Stock, at any time at such holder’s option, into shares of the Common Stock (which converted shares of Common Stock are referred to as “Conversion Shares” herein) at the fixed “Conversion Price” of $10.00, which is subject to proportional adjustment upon the occurrence of any stock split, stock dividend, stock combination and/or similar transactions.

Voluntary Adjustment Right.    Subject to the rules and regulations of the Nasdaq, we have the right, at any time, with the written consent of the Required Holders, to lower the fixed conversion price to any amount and for any period of time deemed appropriate by the Board.

Alternate Conversion Upon a Triggering Event.    Following the occurrence and during the continuance of a Triggering Event (as defined below), each holder may alternatively elect to convert the Series A Preferred Stock at the “Alternate Conversion Price” equal to the lesser of:

The Certificate of Designations contains standard and customary triggering events (each, a “Triggering Event”), including but not limited to: (i) the suspension from trading or the failure to list the Common Stock within certain time periods; (ii) failure to declare or pay any dividend when due; (iii) the failure to timely file or make effective a registration statement on Form S-1 pursuant to the Registration Rights Agreement, dated as of February 14, 2024, by and between us and the holders of Series A Preferred Stock party thereto (the “Registration Rights Agreement”), (iv) our failure to cure a conversion failure of failure to deliver shares of the Common Stock under the Structuring Warrants (as defined below), or notice of our intention not to comply with a request for conversion of any Series A Preferred Stock or a request for exercise of any Structuring Warrants, and (iv) bankruptcy or insolvency of us.

Other Adjustments.    If 90 days or 180 days following the occurrence of the later of (x) the Stockholder Approval Date (as defined below) and (y) the earlier of (a) the effective date of the registration statement to be filed pursuant to the Registration Rights Agreement and (b) the date that the Series A Preferred Stock is eligible to be resold without restriction under Rule 144 of the Securities Act of 1933, as amended (the “Securities Act”), the Conversion Price then in effect is greater than the greater of $1.00 and the Market Price (as defined in the Certificate of Designations) then in effect (the “Adjustment Price”), the Conversion Price shall automatically lower to the Adjustment Price.

Limitations on Conversion.    In no event shall the Series A Preferred Stock be convertible into a number of shares of New Common Stock exceeding 19.99% of the total number of shares of Common Stock outstanding immediately prior to the execution of the Securities Purchase Agreement, except that such limitation shall not apply in the event that we obtain approval from our stockholders for the issuance of such shares in accordance with the applicable stock exchange rules (the date of such approval, the “Stockholder Approval Date”).

Bankruptcy Triggering Event Redemption Right.    Upon any bankruptcy Triggering Event, we shall immediately redeem in cash all amounts due under the Series A Preferred Stock at 25% premium (or, if 18 months following the issuance date, 50% premium) to the greater of (x) the amount of shares of Series A Preferred Stock then outstanding and (y) the equity value of the shares of Series A Preferred Stock then outstanding, unless the holder waives such right to receive such payment. The equity value of the Common Stock underlying the Series A Preferred Stock is calculated using the greatest closing sale price of the Common Stock on any trading day immediately preceding such bankruptcy Triggering Event and the date we make the entire payment required.

Change of Control Exchange.    Upon a change of control of the Company, each holder may require us to exchange the holder’s shares of Series A Preferred Stock for consideration equal to the change of Control Election Price (as defined in the Certificate of Designations), to be satisfied at our election in either (x) cash or (y) rights convertible into such securities or other assets to which such holder would have been entitled with respect to such shares of Common Stock had such shares of Common Stock been held by such holder upon consummation of such corporate event.

Company Optional Redemption.    At any time we shall have the right to redeem in cash all, but not less than all, the shares of Series A Preferred Stock then outstanding at a 20% redemption premium to the greater of (x) the amount of shares being redeemed, and (y) the equity value of the Common Stock underlying the Series A Preferred Stock. The equity value of the Common Stock underlying the Series A Preferred Stock is calculated using the greatest closing sale price of the Common Stock on any trading day immediately preceding the date we notify the holders of our election to redeem and the date we make the entire payment required.

Fundamental Transactions.    The Certificate of Designations prohibit us from entering specified fundamental transactions (including, without limitation, mergers, business combinations and similar transactions) unless we (or our successor) assumes in writing all of our obligations under the Certificate of Designations and the other Transaction Documents (as defined in the Certificate of Designations).

Voting Rights.    The holders of the Series A Preferred Stock shall have no voting power and no right to vote on any matter at any time, either as a separate series or class or together with any other series or class of share of capital stock, and shall not be entitled to call a meeting of such holders for any purpose nor shall they be entitled to participate in any meeting of the holders of Common Stock, except as provided in the Certificate of Designations (or as otherwise required by applicable law).

Covenants.    The Certificate of Designations contains a variety of obligations on our part not to engage in specified activities, which are typical for transactions of this type. In particular, we will not, and will cause our subsidiaries to not, redeem, repurchase or declare any dividend or distribution on any of our capital stock (other than as required under the Certificate of Designations). In addition, we will not issue any preferred stock or issue any other securities that would cause a breach or default under the Certificate of Designations or Structuring Warrants.

Reservation Requirements.    So long as any Series A Preferred Stock remains outstanding, we shall at all times reserve at least 150% of the number of shares of Common Stock as shall from time to time be necessary to effect the conversion of all Series A Preferred Stock then outstanding.

Common Stock

Voting

Each holder of Common Stock is entitled to one vote for each share on all matters submitted to a vote of the stockholders, including the election of directors, with the exception of certain matters relating solely to the terms of one or more outstanding series of preferred stock. Under the Charter, our stockholders do not have cumulative voting rights. Because of this, the holders of a majority of the shares of Common Stock entitled to vote in any election of directors can elect all of the directors standing for election.

Dividends

Subject to preferences that may apply to any then-outstanding Preferred Stock, the holders of Common Stock are entitled to receive ratably those dividends, if any, as may be declared from time to time by the Board out of legally available funds.

Liquidation

In the event of our liquidation, dissolution or winding up, holders of Common Stock will be entitled to share ratably in the net assets legally available for distribution to stockholders after the payment of all of our debts and other liabilities and the satisfaction of any liquidation preference granted to the holders of any then-outstanding shares of Preferred Stock.

Preemptive or Similar Rights

Holders of Common Stock have no preemptive, conversion or subscription rights and there are no redemption or sinking fund provisions applicable to the Common Stock. The rights, preferences and privileges of the holders of Common Stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of Preferred Stock that we may designate in the future.

Warrants

The outstanding warrants consist of (i) warrants initially issued in connection with our initial public offering (the “Public Warrants”), (ii) warrants initially sold in a private placement concurrently with our initial public offering (the “Private Placement Warrants”), (iii) warrants initially issued by CERo Therapeutics, Inc. and converted into warrants to purchase Common Stock in connection with our initial business combination (the “Conversion Warrants”) and (iv) warrants to purchase Common Stock sold in a private placement concurrently with our initial business combination (the “Common Warrants”) and (v) warrants to purchase Series A Preferred Stock sold in a private placement concurrently with our business combination (the “Preferred Warrants” and, together with the Public Warrants, the Private Placement Warrants, the Conversion Warrants and the Common Warrants, the “Warrants”).

Public Warrants

General.     Each Public Warrant entitles the registered holder to purchase one share of Common Stock at a price of $11.50 per share, subject to adjustment as discussed below, commencing 30 days after the completion of the initial business combination. The Public Warrants are governed by the terms of a Warrant Agreement, dated as of October 5, 2021 between us and Continental Stock Transfer & Trust Company, as warrant agent (the “Warrant Agreement”). Pursuant to the Warrant Agreement, a warrant holder may exercise its Public Warrants only for a whole number of shares of Common Stock. This means that only a whole Public Warrant may be exercised at any given time by a warrant holder. No fractional Public Warrants will be issued and only whole Public Warrants will trade. The Public Warrants will expire five years after the completion of the initial business combination, at 5:00 p.m., New York City time, or earlier upon redemption or liquidation.

Registration of Public Warrants.     We will not be obligated to deliver any shares of Common Stock pursuant to the exercise for cash of a Public Warrant and will have no obligation to settle such warrant exercise unless a registration statement under the Securities Act with respect to the shares of Common Stock underlying the Public Warrants is then effective and a prospectus relating thereto is current, subject to our satisfying our obligations described below with respect to registration. No Public Warrant will be exercisable and we will not be obligated to issue shares of Common Stock upon exercise of a Public Warrant unless Common Stock issuable upon such warrant exercise has been registered, qualified or deemed to be exempt from the registration or qualifications requirements of the securities laws of the state of residence of the registered holder of the Public Warrants. Notwithstanding the foregoing, if a registration statement covering the shares of Common Stock issuable upon exercise of the Public Warrants has not been declared effective by the end of 60 business days following the closing of the initial business combination, warrantholders may, until such time as there is an effective registration statement and during any period when we shall have failed to maintain an effective registration statement, exercise Public Warrants on a cashless basis pursuant to the exemption provided by Section 3(a)(9) of the Securities Act.

We have agreed that as soon as practicable, but in no event later than 20 business days after the closing of the initial business combination, we will use our best efforts to file with the SEC, and within 60 business days following the initial business combination to have declared effective, a registration statement covering the issuance of the shares of Common Stock issuable upon exercise of the Public Warrants and to maintain a current prospectus relating to those shares of Common Stock until the Public Warrants expire or are redeemed, as specified in the Warrant Agreement. If a registration statement covering the shares of Common Stock issuable upon exercise of the Public Warrants is not effective by the 60^th business day after the closing of the initial business combination, warrantholders may, until such time as there is an effective registration statement and during any period when we will have failed to maintain an effective registration statement, exercise Public Warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act or another exemption. In addition to the above, if Common Stock is at the time of any exercise of a Public Warrant not listed on a national securities exchange such that it satisfies the definition of a “covered security” under Section 18(b)(1) of the Securities Act, we may, at our option, require holders of Public Warrants who exercise their Public Warrants to do so on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act and, in the event we so elects, we will not be required to file or maintain in effect a registration statement, and in the event it does not so elect, it will use our best efforts to register or qualify the shares under applicable blue sky laws to the extent an exemption is not available.

Redemption of Warrants. Once the Public Warrants become exercisable, we may call the Public Warrants for redemption:

If and when the Public Warrants become redeemable by us, it may exercise its redemption right even if it is unable to register or qualify the underlying securities for sale under all applicable state securities laws.

We have established the last of the redemption criterion discussed above to prevent a redemption call unless there is at the time of the call a significant premium to the warrant exercise price. If the foregoing conditions are satisfied and we issue a notice of redemption of the Public Warrants, each warrant holder will be entitled to exercise its warrant prior to the scheduled redemption date. However, the price of the Common Stock may fall below the $18.00 redemption trigger price (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) as well as the $11.50 (for whole shares) warrant exercise price after the redemption notice is issued.

Cashless Exercise.    If we call the Public Warrants for redemption as described above, our management will have the option to require any holder that wishes to exercise its Public Warrant to do so on a “cashless basis.” In determining whether to require all holders to exercise their Public Warrants on a “cashless basis,” Our management will consider, among other factors, our cash position, the number of Public Warrants that are outstanding and the dilutive effect on our stockholders of issuing the maximum number of shares of Common Stock issuable upon the exercise of our warrants. If our management takes advantage of this option, all holders of Public Warrants would pay the exercise price by surrendering their warrants for that number of shares of Common Stock equal to the quotient obtained by dividing (x) the product of the number of shares of Common Stock underlying the Public Warrants, multiplied by the difference between the exercise price of the Public Warrants and the “fair market value” (defined below) by (y) the fair market value. The “fair market value” shall mean the average reported last sale price of the Common Stock for the 10 trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of Public Warrants. If our management takes advantage of this option, the notice of redemption will contain the information necessary to calculate the number of shares of Common Stock to be received upon exercise of the Public Warrants, including the “fair market value” in such case. Requiring a cashless exercise in this manner will reduce the number of shares to be issued and thereby lessen the dilutive effect of a warrant redemption.

A holder of a Public Warrant may notify us in writing in the event it elects to be subject to a requirement that such holder will not have the right to exercise such warrant, to the extent that after giving effect to such exercise, such person (together with such person’s affiliates), to the warrant agent’s actual knowledge, would beneficially own in excess 9.8% (or such other amount as a holder may specify) of the shares of Common Stock outstanding immediately after giving effect to such exercise.

Anti-Dilution Adjustments.     If the number of outstanding shares of Common Stock is increased by a stock dividend payable in shares of Common Stock, or by a split-up of shares of Common Stock or other similar event, then, on the effective date of such stock dividend, split-up or similar event, the number of shares of Common Stock issuable on exercise of each warrant will be increased in proportion to such increase in the outstanding shares of Common Stock. A rights offering to holders of Common Stock entitling holders to purchase shares of Common Stock at a price less than the fair market value will be deemed a stock dividend of a number of shares of Common Stock equal to the product of (i) the number of shares of Common Stock actually sold in such rights offering (or issuable under any other equity securities sold in such rights offering that are convertible into or exercisable for Common Stock) multiplied by (ii) one (1) minus the quotient of (x) the price per share of Common Stock paid in such rights offering divided by (y) the fair market value. For these purposes (i) if the rights offering is for securities convertible into or exercisable for Common Stock, in determining the price payable for Common Stock, there will be taken into account any consideration received for such rights, as well as any additional amount payable upon exercise or conversion and (ii) fair market value means the volume weighted average price of Common Stock as reported during the 10 trading day period ending on the trading day prior to the first date on which the shares of Common Stock trade on the applicable exchange or in the applicable market, regular way, without the right to receive such rights.

In addition, if we, at any time while the Public Warrants are outstanding and unexpired, pay a dividend or makes a distribution in cash, securities or other assets to the holders of Common Stock on account of such shares of Common Stock (or other shares of our capital stock into which the Public Warrants are convertible), other than (a) as described above or (b) any cash dividends or cash distributions which, when combined on a per share basis with all other cash dividends and cash distributions paid on the shares of Common Stock during the 365-day period ending on the date of declaration of such dividend or distribution does not exceed $0.50 (as adjusted to appropriately reflect any other adjustments and excluding cash dividends or cash distributions that resulted in an adjustment to the exercise price or to the number of shares of Common Stock issuable on exercise of each warrant) but only with respect to the amount of the aggregate cash dividends or cash distributions equal to or less than $0.50 per share.

If the number of outstanding shares of Common Stock is decreased by a consolidation, combination, reverse stock split or reclassification of shares of Common Stock or other similar event, then, on the effective date of such consolidation, combination, reverse stock split, reclassification or similar event, the number of shares of Common Stock issuable on exercise of each Public Warrant will be decreased in proportion to such decrease in outstanding shares of Common Stock.

Whenever the number of shares of Common Stock purchasable upon the exercise of the Public Warrants is adjusted, as described above, the warrant exercise price will be adjusted by multiplying the warrant exercise price immediately prior to such adjustment b a fraction (x) the numerator of which will be the number of shares of Common Stock purchasable upon the exercise of the Public Warrants immediately prior to such adjustment, and (y) the denominator of which will be the number of shares of Common Stock to purchase immediately thereafter.

In case of any reclassification or reorganization of the issued and outstanding shares of Common Stock (other than those described above or that solely affects the par value of such shares of Common Stock), or in the case of any merger or consolidation of us with or into another entity (other than a consolidation or merger in which we are the continuing corporation and that does not result in any reclassification or reorganization of our issued and outstanding shares of Common Stock) in which any “person” or “group” (as such terms are used in Sections 13(d) and 14(d) of the Exchange Act) acquired more than 50% of the voting power of our securities in a transaction that results in a Change of Control Transaction (as defined in the Warrant Agreement), or in the case of any sale or conveyance to another corporation or entity of the assets or other property of us as an entirety or substantially as an entirety, the holders of Public Warrants will thereafter have the right to purchase and receive, upon the basis and upon the terms and conditions specified in the Public Warrants and in lieu of shares of Common Stock immediately theretofore purchasable and receivable upon the exercise of the rights represented thereby, the kind and amount of shares of Common Stock or other securities or property (including cash) receivable upon such reclassification, reorganization, merger or consolidation, or upon a dissolution following any such sale or transfer, that the holder of the Public Warrants would have received if such holder had exercised their Public Warrants immediately prior to such event. However, if such holders were entitled to exercise a right of election as to the kind or amount of securities, cash or other assets receivable upon such consolidation or merger, then the kind and amount of securities, cash or other assets for which each Public Warrant will become exercisable will be deemed to be the weighted average of the kind and amount received per share by such holders in such consolidation or merger that affirmatively make such election. If less than 70% of the consideration receivable by the holders of Common Stock in such a transaction is payable in the form of Common Stock in the successor entity that is listed for trading on a national securities exchange or is quoted in an established over-the-counter market, or is to be so listed for trading or quoted immediately following such event, and if the registered holder of the Public Warrant properly exercises the Public Warrant within thirty days following public disclosure of such transaction pursuant to a Current Report on Form 8-K, the warrant exercise price will be reduced as specified in the Warrant Agreement based on the Black-Scholes value (as defined in the Warrant Agreement) of the Public Warrant. The purpose of such exercise price reduction is to provide additional value to holders of the Public Warrants when an extraordinary transaction occurs during the exercise period of the Public Warrants pursuant to which the holders of the Public Warrants otherwise do not receive the full potential value of the Public Warrants.

The Public Warrant may be exercised upon surrender of the warrant certificate on or prior to the expiration date at the offices of the warrant agent, with the exercise form on the reverse side of the warrant certificate completed and executed as indicated, accompanied by full payment of the exercise price (or on a cashless basis, if applicable), by certified or official bank check payable to us, for the number of Public Warrants being exercised. The warrant holders do not have the rights or privileges of holders of Common Stock and any voting rights until they exercise their Public Warrants and receive shares of Common Stock. After the issuance of shares of Common Stock upon exercise of the Public Warrants, each holder will be entitled to one vote for each share held of record on all matters to be voted on by stockholders.

Public Warrants may be exercised only for a whole number of shares of Common Stock. No fractional shares will be issued upon exercise of the Public Warrants. If, upon exercise of the Public Warrants, a holder would be entitled to receive a fractional interest in a share, we will, upon exercise, round down to the nearest whole number of shares of Common Stock to be issued to the warrant holder. As a result, warrant holders not purchasing an even number of Public Warrants must sell any odd number of Public Warrants in order to obtain full value from the fractional interest that will not be issued.

The Public Warrants were issued in registered form under the Warrant Agreement. You should review a copy of the Warrant Agreement, which is filed as an exhibit to our registration statement on Form S-4 filed on June 7, 2023, for a complete description of the terms and conditions applicable to the Public Warrants. The Warrant Agreement provides that the terms of the Public Warrants may be amended without the consent of any holder to cure any ambiguity or correct any defective provision, but requires the approval by the holders of a majority of the then-outstanding Public Warrants to make any changes that adversely affect the interests of the registered holders of Public Warrants.

Placement Warrants

The Private Placement Warrants (including the Common Stock issuable upon exercise of the Private Placement Warrants) are not transferable, assignable or salable until 30 days after the completion of our business combination (subject to limited exceptions). In addition, for as long as Private Placement Warrants are held by Cantor Fitzgerald& Co. and/or its designees or affiliates, such Private Placement Warrants will be subject to a lock-up in compliance with FINRA Rule 5110(e) and may not be exercised after five years from the commencement of sales of our initial public offering in accordance with FINRA Rule 5110(g)(8)(A). The Private Placement Warrants will be redeemable by us and exercisable by the holders on the same basis as the Public Warrants.

Conversion Warrants

Exercise Price.    The Conversion Warrants will initially be exercisable for cash at an exercise price equal to $10.00. The exercise price is subject to adjustment for stock splits, combinations and similar events, and, in the event of stock dividends and splits, the number of shares of Common Stock issuable upon the exercise of the Conversion Warrant will also be adjusted so that the aggregate exercise price shall be the same immediately before and immediately after any such adjustment.

Exercise Period.    The Conversion Warrants will expire five years after their issuance, or November 14, 2024.

Automatic Conversion.    The Conversion Warrants will automatically convert at the end of the exercise period if the fair market value (as determined in the Conversion Warrants) of a share of Common Stock underlying the Conversion Warrants is greater than the exercise price in effect on such date.

Common Warrants

Exercise Price.    The Common Warrants will initially be exercisable for cash at an exercise price equal to the greater of (x) $9.20 (as adjusted for stock splits, stock dividends, stock combinations, recapitalizations and similar events) and (y) the closing price of the Common Stock on the trading day immediately prior to the Subscription Date (as defined in the Common Warrant). The exercise price is subject to adjustment for stock splits, combinations and similar events, and, in the event of stock dividends and splits, the number of shares of Common Stock issuable upon the exercise of the Common Warrant will also be adjusted so that the aggregate exercise price shall be the same immediately before and immediately after any such adjustment.

Exercise Period.    The Common Warrants will be exercisable beginning six months after the consummation of the issuance date (the “Initial Exercisability Date”) and expiring on the third anniversary of the Initial Exercisability Date. The Common Warrants require “buy-in” payments to be made by us for failure to deliver any shares of Common Stock issuable upon exercise.

Cashless Exercise.    If at the time of exercise of the Common Warrants, there is no effective registration statement registering the shares of the Common Stock underlying the Common Warrants, such warrants may be exercised on a cashless basis pursuant to their terms.

Purchase Rights; Participation Rights.    If we issue options, convertible securities, warrants, shares, or similar securities to holders of Common Stock, each holder of Common Warrants has the right to acquire the same as if the holder had exercised its Common Warrant. The holders of Common Warrants are entitled to receive any dividends paid or distributions made to our holders of Common Stock on an “as if converted” basis.

Fundamental Transactions.    The Common Warrants prohibit us from entering into specified fundamental transactions unless the successor entity assumes all of our obligations under the Common Warrants under a written agreement before the transaction is completed. Upon specified corporate events, a holder of Common Warrants will thereafter have the right to receive upon an exercise such shares, securities, cash, assets or any other property whatsoever which the holder would have been entitled to receive upon the happening of the applicable corporate event had the Common Warrant been exercised immediately prior to the applicable corporate event. When there is a transaction involving specified changes of control, a holder of Common Warrants will have the right to force us to repurchase the holder’s Common Warrant for a purchase price in cash equal to the Black-Scholes value, as calculated under the Common Warrants, of the then unexercised portion of the Common Warrant.

Preferred Warrants

Exercise Price.    The Preferred Warrants will initially be exercisable for cash at an exercise price equal to $1,000. The exercise price is subject to adjustment for stock splits, combinations and similar events, and, in the event of stock dividends and splits, the number of shares of Series A Preferred Stock issuable upon the exercise of the Preferred Warrant will also be adjusted so that the aggregate exercise price shall be the same immediately before and immediately after any such adjustment.

Exercise Period.    The Preferred Warrants will expire on the first anniversary of the closing of the initial business combination, or February 14, 2025.

Forced Exercise.    We have the right to require the holders of Preferred Warrants to exercise such Preferred Warrants into up to an aggregate number of shares of Preferred Stock equal to the holder’s pro rata amount of 2,000 Preferred Shares.

Fundamental Transactions.    The Preferred Warrants prohibit us from entering into specified fundamental transactions unless the successor entity assumes all of our obligations under the Preferred Warrants under a written agreement before the transaction is completed. Upon specified corporate events, a holder of Preferred Warrants will thereafter have the right to receive upon an exercise such shares, securities, cash, assets or any other property whatsoever which the holder would have been entitled to receive upon the happening of the applicable corporate event had the Preferred Warrant been exercised immediately prior to the applicable corporate event.

Anti-Takeover Provisions

Section 203 of the Delaware General Corporation Law

We are subject to Section 203 of the DGCL, which generally prohibits a publicly held Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years after the date that such stockholder became an interested stockholder, with the following exceptions:

In general, Section 203 defines a “business combination” to include the following:

In general, Section 203 defines an “interested stockholder” as an entity or person who, together with the person’s affiliates and associates, beneficially owns or, within three years prior to the time of determination of interested stockholder status, did own 15% or more of the outstanding voting stock of the corporation.

A Delaware corporation may “opt out” of these provisions with an express provision in its original certificate of incorporation or an express provision in its amended and restated certificate of incorporation or amended and restated bylaws resulting from a stockholders’ amendment approved by at least a majority of the outstanding voting shares. We have not opted out of these provisions. As a result, mergers or other takeover or change in control attempts of us may be discouraged or prevented.

Among other things, the Charter and Bylaws:

The amendment of a number of these provisions would require approval by the holders of at least 66 2/3% of the voting power of all of our then-outstanding capital stock entitled to vote generally in the election of directors, voting together as a single class.

The combination of these provisions will make it more difficult for our existing stockholders to replace the Board, as well as for another party to obtain control of us by replacing the Board. Since the Board has the power to retain and discharge our officers, these provisions could also make it more difficult for existing stockholders or another party to effect a change in management. In addition, the authorization of undesignated preferred stock makes it possible for the Board to issue preferred stock with voting or other rights or preferences that could impede the success of any attempt to change our control.

These provisions are intended to enhance the likelihood of continued stability in the composition of our Board and our policies and to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to reduce our vulnerability to hostile takeovers and 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 may have the effect of delaying changes in our control or management. As a consequence, these provisions may also inhibit fluctuations in the market price of our stock.

The Charter and Bylaws provide that, unless we consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware (or, if the Court of Chancery of the State of Delaware lacks subject matter jurisdiction, any state court located within the State of Delaware or, if all such state courts lack subject matter jurisdiction, the federal district court for the District of Delaware) and any appellate court therefrom will be the sole and exclusive forum for the following claims or causes of action under Delaware statutory or common law: (A) any derivative claim or cause of action brought on our behalf, (B) any claim or cause of action for breach of a fiduciary duty owed by any of our then current or former directors, officers, or other employees to us or our stockholders, (C) any claim or cause of action against it or any of our current or former directors, officers or other employees arising out of or pursuant to any provision of the DGCL, the Charter or the Bylaws (as each may be amended from time to time), (D) any claim or cause of action seeking to interpret, apply, enforce or determine the validity of the Charter or Bylaws (as each may be amended from time to time, including any right, obligation, or remedy thereunder) (E) any claim or cause of action as to which the DGCL confers jurisdiction on the Court of Chancery of the State of Delaware or (F) any claim or cause of action against us or any of our then current or former directors, officers or other employees, governed by the internal-affairs doctrine or otherwise related to our internal affairs, in each case to the fullest extent permitted by law and subject to the court having personal jurisdiction over the indispensable parties named as defendants. These provisions do not apply to claims or causes of action brought to enforce a liability or duty created by the Securities Act, the Exchange Act or any other claim where the U.S. federal courts have exclusive jurisdiction. Furthermore, Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all such Securities Act actions. Accordingly, both state and federal courts have jurisdiction to entertain such claims. To prevent having to litigate claims in multiple jurisdictions and the threat of inconsistent or contrary rulings by different courts, among other considerations, the Charter and Bylaws will further provide that, unless we consent in writing to the selection of an alternative forum, to the fullest extent permitted by law, the federal district courts of the United States will be the exclusive forum for the resolution of any action or proceeding asserting a cause of action arising under the Securities Act, including all causes of action asserted against any defendant named in such complaint. For the avoidance of doubt, this provision is intended to benefit and may be enforced by our officers and directors, the underwriters engaged in respect to any offering giving rise to such complaint giving rise to such complaint, any other professional entity whose profession gives authority to a statement made by that person or entity and who has prepared or certified any part of the documents underlying the Business Combination. While the Delaware courts have determined that such choice of forum provisions are facially valid, a stockholder may nevertheless seek to bring a claim in a venue other than those designated in the exclusive forum provisions. In such instance, we would expect to vigorously assert the validity and enforceability of the exclusive forum provisions of the Charter and Bylaws.

These exclusive forum provisions may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers, or other employees and may discourage these types of lawsuits, or could result in increased costs for a stockholder to bring a claim, particularly if they do not reside in or near Delaware, both of which may discourage lawsuits against us or our directors, officers and employees.

Furthermore, the enforceability of similar choice of forum provisions in other companies’ certificates of incorporation or bylaws has been challenged in legal proceedings, and it is possible that a court could find these types of provisions to be inapplicable or unenforceable.
