Description of Securities

Exhibit 4.5

DESCRIPTION OF SECURITIES

General

As of March 24, 2023 Revelstone Capital Acquisition Corp. 16,500,000 shares of Class A common stock, par value $0.0001 per share, and 4,125,000 shares of Class B common stock, par value $0.0001 per share, issued and outstanding.   We have three classes of securities registered under Section 12 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”): (1) our units; (2) our common stock; and (3) our warrants.

The following description of our units, common stock, and warrants is a summary and does not purport to be complete. It is subject to and qualified in its entirety by reference to our Second Amended and Restated Certificate of Incorporation, which is incorporated by reference as an exhibit to the Annual Report on Form 10-K of which this Exhibit 4.5 is a part.

Terms not otherwise defined herein shall have the meaning assigned to them in the Annual Report on Form 10-K of which this Exhibit 4.5 is a part.

Units

Each unit has an offering price of $10.00 and consists of one share of our Class A common stock and one-half of one redeemable warrant. Each whole warrant entitles the holder thereof to purchase one share of our Class A common stock at a price of $11.50 per share, subject to adjustment as described in the final prospectus dated December 16, 2021. Pursuant to the warrant agreement, a warrant holder may exercise its warrants only for a whole number of the company’s shares of our Class A common stock. This means only a whole warrant may be exercised at any given time by a warrant holder.

The shares of our Class A common stock and warrants constituting the units will began separate trading on February 7, 2022. Once the shares of our Class A common stock and warrants commence separate trading, holders have the option to continue to hold units or separate their units into the component securities. Holders will need to have their brokers contact our transfer agent in order to separate the units into shares of our Class A common stock and warrants. Additionally, the units will automatically separate into their component parts and will not be traded after completion of our initial business combination. No fractional warrants will be issued upon separation of the units and only whole warrants will trade. Accordingly, unless you purchase at least three units, you will not be able to receive or trade a whole warrant.

In no event will the shares of our Class A common stock and warrants be traded separately until we have filed with the SEC a Current Report on Form 8-K which includes an audited balance sheet of the company reflecting our receipt of the gross proceeds at the closing of this offering. We will file the Current Report on Form 8-K promptly after the closing of this offering which will include this audited balance sheet. If the underwriters’ over-allotment option is exercised following the initial filing of such Current Report on Form 8-K, a second or amended Current Report on Form 8-K will be filed to provide updated financial information to reflect the exercise of the underwriters’ over-allotment option.

Common Stock

There are 20,625,000 shares of our common stock will be outstanding including:

​

Common stockholders of record are entitled to one vote for each share held on all matters to be voted on by stockholders. Holders of shares of our Class B common stock will have the right to elect all of our directors prior to the consummation of our initial business combination. On any other matter submitted to a vote of our stockholders, holders of shares of our Class B common stock and holders of shares of our Class A common stock will vote together as a single class, except as required by applicable law or stock exchange rule. These provisions of our second amended and restated certificate of incorporation may only be amended if approved by a majority of at least 90% of our common stock voting at a stockholder meeting. Unless specified in our second amended and restated certificate of incorporation or bylaws, or as required by applicable law or stock exchange rules, the affirmative vote of a majority of our shares of common stock that are voted is required to approve any such matter voted on by our stockholders (other than the election of directors). Directors will be divided into three classes, each of which will generally serve for a term of three years with only one class elected in each year. There is no cumulative voting with respect to the election of directors. Our stockholders are entitled to receive ratable dividends when, as and if declared by the board of directors out of funds legally available therefor.

Because our second amended and restated certificate of incorporation authorizes the issuance of up to 180,000,000 shares of our Class A common stock, if we were to enter into a business combination, we may (depending on the terms of such a business combination) be required to increase the number of shares of common stock which we are authorized to issue at the same time as our stockholders vote on the business combination to the extent we seek stockholder approval in connection with our initial business combination.

In accordance with Nasdaq corporate governance requirements, we are not required to hold an annual meeting until not later than one year after our first fiscal year end following our listing on Nasdaq. Under Section 211(b) of the DGCL, we are, however, required to hold an annual meeting of stockholders for the purposes of electing directors in accordance with our bylaws unless such election is made by written consent in lieu of such a meeting. We may not hold an annual meeting of stockholders to elect new directors prior to the consummation of our initial business combination, and thus we may not be in compliance with Section 211(b) of the DGCL, which requires an annual meeting. Therefore, if our stockholders want us to hold an annual meeting prior to the consummation of our initial business combination, they may attempt to force us to hold one by submitting an application to the Delaware Court of Chancery in accordance with Section 211(c) of the DGCL.

We will provide our public stockholders with the opportunity to redeem all or a portion of their shares upon the completion of our initial business combination at a per share price, payable in cash, equal to the aggregate amount then on deposit in the trust account as of two business days prior to the consummation of our initial business combination, including interest (net of permitted withdrawals), divided by the number of then outstanding public shares, subject to the limitations described herein. The amount in the trust account is initially anticipated to be $10.10 per public share. The per share amount we will distribute to investors who properly redeem their shares will not be reduced by the deferred underwriting commissions we will pay to the underwriters. The redemption right will include the requirement that any beneficial owner on whose behalf a redemption right is being exercised must identify itself in order to validly redeem its shares. Each public stockholder may elect to redeem its public shares without voting, and if they do vote, irrespective of whether they vote for or against the proposed transaction. Our initial stockholders, anchor investors that will hold founder shares, officers and directors have entered into a letter agreement with us, pursuant to which they have agreed to waive their redemption rights with respect to any founder shares and any public shares held by them in connection with the completion of our initial business combination. Permitted transferees of our sponsor, officers or directors will be subject to the same obligations. Unlike many blank check companies that hold stockholder votes and conduct proxy solicitations in conjunction with their initial business combinations and provide for related redemptions of public shares for cash upon completion of such initial business combinations even when a vote is not required by applicable law or stock exchange listing requirements, if a stockholder vote is not required by applicable law or stock exchange listing requirements and we do not decide to hold a stockholder vote for business or other reasons, we will, pursuant to our second amended and restated certificate of incorporation, conductthe redemptions pursuant to the tender offer rules of the SEC, and file tender offer documents with the SEC prior to completing our initial business combination. Our second amended and restated certificate of incorporation requires these tender offer documents to contain substantially the same financial and other information about the initial business combination and the redemption rights as is required under the SEC’s proxy rules. If, however, a stockholder approval of the transaction is required by applicable law or stock exchange rules, or we decide to obtain stockholder

​

approval for business or other reasons, we will, like many blank check companies, offer to redeem shares in conjunction with a proxy solicitation pursuant to the proxy rules and not pursuant to the tender offer rules. If we seek stockholder approval, unless a different vote is required by applicable law or stock exchange rules, we will complete our initial business combination only if a majority of the shares of common stock voted are voted in favor of our initial business combination. Unless otherwise required by applicable law or stock exchange rules, a quorum for such meeting will consist of the holders present in person or by proxy of shares of outstanding capital stock of the company representing a majority of the voting power of all outstanding shares of capital stock of the company entitled to vote at such meeting. However, the participation of our sponsor, officers, directors, advisors or any of their respective affiliates in privately-negotiated transactions (as described in the final prospectus), if any, could result in the approval of our initial business combination even if a majority of our public stockholders vote, or indicate their intention to vote, against such business combination.

For purposes of seeking approval of the majority of our outstanding shares of common stock, non-votes will have no effect on the approval of our initial business combination once a quorum is obtained. We intend to give approximately 30 days (but not less than 10 days nor more than 60 days) prior written notice of any such meeting, if required, at which a vote shall be taken to approve our initial business combination. These quorum and voting thresholds and agreements may make it more likely that we will consummate our initial business combination.

If we seek stockholder approval of our initial business combination and we do not conduct redemptions in connection with our initial business combination pursuant to the tender offer rules, our second amended and restated certificate of incorporation provides that a public stockholder, together with any affiliate of such stockholder or any other person with whom such stockholder is acting in concert or as a “group” (as defined under Section 13 of the Exchange Act), will be restricted from redeeming more than an aggregate of 15% of the shares sold in this offering, without our prior consent, which we refer to as the “Excess Shares.” However, we would not be restricting our stockholders’ ability to vote all of their shares (including Excess Shares) for or against our initial business combination. Our stockholders’ inability to redeem the Excess Shares will reduce their influence over our ability to complete our initial business combination, and such stockholders could suffer a material loss in their investment if they sell such Excess Shares on the open market. Additionally, such stockholders will not receive redemption distributions with respect to the Excess Shares if we complete the business combination. And, as a result, such stockholders will continue to hold that number of shares exceeding 15% and, in order to dispose such shares would be required to sell their stock in open market transactions, potentially at a loss.

If we seek stockholder approval in connection with our initial business combination, our initial stockholders, anchor investors that will hold founder shares, officers and directors have (and their respective permitted transferees, as applicable, will agree) agreed to vote any founder shares and any public shares held by them in favor of our initial business combination (except with respect to public shares held by the anchor investors). As a result, in addition to the founder shares, we would need 5,625,000, or 37.5% (assuming all issued and outstanding shares are voted and the option to purchase additional units is not exercised), or 937,500, or 6.25% (assuming only the minimum number of shares representing a quorum are voted and the over-allotment option is not exercised), of the 15,000,000 public shares sold in this offering to be voted in favor of our initial business combination in order to have such initial business combination approved. Additionally, each public stockholder may elect to redeem its public shares without voting, and if they do vote, irrespective of whether they vote for or against the proposed transaction.

Pursuant to our amended and restated certificate of incorporation, if we are unable to complete our initial business combination within 18 months of the closing of this offering, we will: (1) cease all operations except for the purpose of winding up; (2) as promptly as reasonably possible but no more than ten business days thereafter, subject to lawfully available funds therefor, redeem the public shares, at a per share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including interest (net of permitted withdrawals and up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding public shares, which redemption will completely extinguish public stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law; and (3) as promptly as reasonably possible following such redemption, subject to the approval of our remaining stockholders and our board of directors, dissolve and liquidate, subject in each case to our obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law. Our initial stockholders, anchor investors that will hold founder shares, officers and directors have entered into a letter agreement with us, pursuant to which they have agreed to waive their rights to liquidating distributions from the trust account with respect to any founder shares held by them if we fail to complete our initial business combination within

​

18 months of the closing of this offering. However, if our sponsor or any of our officers or directors acquires public shares after this offering, they will be entitled to liquidating distributions from the trust account with respect to such public shares if we fail to complete our initial business combination within 18 months of the closing of this offering.

In the event of a liquidation, dissolution or winding up of the company after a business combination, our stockholders are entitled to share ratably in all assets remaining available for distribution to them after payment of liabilities and after provision is made for each class of stock, if any, having preference over the common stock. Our stockholders have no preemptive or other subscription rights. There are no sinking fund provisions applicable to the common stock, except that we will provide our stockholders with the opportunity to redeem their public shares for cash equal to their pro rata share of the aggregate amount on deposit in the trust account as of two business days prior to the consummation of our initial business combination, including interest (net of permitted withdrawals), upon the completion of our initial business combination, subject to the limitations described herein.

Founder Shares

The founder shares are designated as shares of our Class B common stock and are identical to the shares of our Class A common stock included in the units sold in this offering, and holders of founder shares have the same stockholder rights as public stockholders, except that: (1) prior to our initial business combination, only holders of the founder shares have the right to vote on the appointment of directors and holders of a majority of our founder shares may remove a member of the board of directors for any reason; (2) the founder shares are subject to certain transfer restrictions, as described in more detail below; (3) our initial stockholders, anchor investors that will hold founder shares, directors and officers have entered into a letter agreement with us, pursuant to which they have agreed to waive: (i) their redemption rights with respect to any founder shares and public shares held by them, as applicable, in connection with the completion of our initial business combination; (ii) their redemption rights with respect to any founder shares and public shares held by them in connection with a stockholder vote to amend our second amended and restated certificate of incorporation (A) to modify the substance or timing of our obligation to allow redemption in connection with our initial business combination or to redeem 100% of our public shares if we do not complete our initial business combination within 18 months from the closing of this offering or during any Extension Period, or (B) with respect to any other provision relating to stockholders’ rights or pre-initial business combination activity; and (iii) their rights to liquidating distributions from the trust account with respect to any founder shares they hold if we fail to complete our initial business combination within 18 months from the closing of this offering or during any Extension Period (although they will be entitled to liquidating distributions from the trust account with respect to any public shares they hold if we fail to complete our initial business combination within the prescribed time frame); (4) the founder shares will automatically convert into shares of our Class A common stock at the time of our initial business combination, or earlier at the option of the holder, on a one-for-one basis, subject to adjustment pursuant to certain anti-dilution rights, as described in more detail below; and (5) the founder shares are entitled to registration rights once converted. If we submit our initial business combination to our public stockholders for a vote, our initial stockholders, anchor investors that will hold founder shares, directors and officers have agreed (and their respective permitted transferees will agree), pursuant to the terms of a letter agreement entered into with us, to vote their founder shares and any public shares held by them purchased during or after this offering in favor of our initial business combination. In addition, each of our anchor investors has entered into an investment agreement with us pursuant to which they have agreed to vote any founder shares held by them offering in favor of our initial business combination. Although the anchor investors are not contractually obligated to vote any public shares they own an incentive for them to do so.in favor of our initial business combination, their ownership of founder shares may provide an incentive for them to do so.

The founder shares will automatically convert into shares of our Class A common stock at the time of our initial business combination, or earlier at the option of the holder, on a one-for-one basis, subject to adjustment for stock splits, stock dividends, rights issuances, consolidations, reorganizations, recapitalizations and the like, and subject to further adjustment as provided herein. In the case that additional shares of our Class A common stock, or equity-linked securities, are issued or deemed issued in excess of the amounts issued in this offering and related to the closing of our initial business combination, the ratio at which the shares of our Class B common stock will convert into shares of our Class A common stock will be adjusted (unless the holders of a majority of the issued and outstanding shares of our Class B common stock agree to waive such anti-dilution adjustment with respect to any such issuance or deemed issuance) so that the number of shares of our Class A common stock issuable upon conversion of all shares of our Class B common stock will equal, in the aggregate, on an as-converted basis, 20% of the sum of all shares of common

​

stock issued and outstanding upon the completion of this offering plus all shares of our Class A common stock and equity-linked securities issued or deemed issued in connection with our initial business combination, excluding any shares or equity-linked securities issued, or to be issued, to any seller in our initial business combination. The term “equity-linked securities” refers to any debt or equity securities that are convertible, exercisable or exchangeable for shares of our Class A common stock issued in a financing transaction in connection with our initial business combination, including but not limited to a private placement of equity or debt securities.

With certain limited exceptions, the founder shares are not transferable, assignable or salable (except to our directors and officers and other persons or entities affiliated with our sponsor, each of whom will be subject to the same transfer restrictions) until the earlier of: (A) one year after the completion of our initial business combination; and (B) subsequent to our initial business combination (x) if the last reported sale price of shares of our Class A common stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, rights issuances, consolidations, reorganizations, recapitalizations and other similar transactions) for any 20 trading days within any 30-trading day period commencing at least 150 days after our initial business combination or (y) the date on which we complete a liquidation, merger, capital stock exchange, reorganization or other similar transaction that results in all of our public stockholders having the right to exchange their shares of common stock for cash, securities or other property.

Preferred Stock

Our second amended and restated certificate of incorporation authorizes 1,000,000 shares of preferred stock and provide that shares of preferred stock may be issued from time to time in one or more series. Our board of directors are authorized to fix the voting rights, if any, designations, powers, preferences, the relative, participating, optional or other special rights and any qualifications, limitations and restrictions thereof, applicable to the shares of each series. Our board of directors will be able to, without stockholder approval, issue shares of preferred stock with voting and other rights that could adversely affect the voting power and other rights of the holders of the shares of common stock and could have anti-takeover effects. The ability of our board of directors to issue shares of 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. We have no shares of preferred stock issued and outstanding at the date hereof. Although we do not currently intend to issue any shares of preferred stock, we cannot assure you that we will not do so in the future. No shares of preferred stock have been issued or registered in this offering.

Redeemable Warrants

No warrants are currently outstanding. Each warrant entitles the registered holder to purchase one share of Class A common stock at a price of $11.50 per share, subject to adjustment as discussed below, at any time commencing on the later of twelve months from the date of the initial public offering or 30 days after the completion of our initial business combination. However, no warrants will be exercisable for cash unless we have an effective and current registration statement covering the shares of Class A common stock issuable upon exercise of the warrants and a current prospectus relating to such shares of Class A common stock. Notwithstanding the foregoing, if a registration statement covering the shares of Class A common stock issuable upon exercise of the public warrants is not effective within a specified period following the consummation of our initial business combination, warrant holders 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 warrants on a cashless basis pursuant to the exemption provided by Section 3(a)(9) of the Securities Act, provided that such exemption is available. If that exemption, or another exemption, is not available, holders will not be able to exercise their warrants on a cashless basis. In the event of such cashless exercise, each holder would pay the exercise price by surrendering the warrants for that number of shares of Class A common stock equal to the quotient obtained by dividing (x) the product of the number of shares of Class A common stock underlying the warrants, multiplied by the difference between the exercise price of the warrants and the “fair market value” (defined below) by (y) the fair market value. The “fair market value” for this purpose will mean the average reported last sale price of the shares of Class A common stock for the 5 trading days ending on the trading day prior to the date of exercise. The warrants will expire on the fifth anniversary of our completion of an initial business combination, at 5:00 p.m., New York City time, or earlier upon redemption or liquidation.

The private warrants, as well as any warrants underlying additional units we issue to our sponsor, officers, directors, initial stockholders, any anchor investors holding founder shares or their affiliates in payment of working capital loans made to us, will be identical to the warrants underlying the units offered in the initial public offering.

​

We may call the warrants for redemption, in whole and not in part, at a price of $0.01 per warrant,

The right to exercise will be forfeited unless the warrants are exercised prior to the date specified in the notice of redemption. On and after the redemption date, a record holder of a warrant will have no further rights except to receive the redemption price for such holder’s warrant upon surrender of such warrant.

The redemption criteria for our warrants have been established at a price which is intended to provide warrant holders a reasonable premium to the initial exercise price and provide a sufficient differential between the then- prevailing share price and the warrant exercise price so that if the share price declines as a result of our redemption call, the redemption will not cause the share price to drop below the exercise price of the warrants.

If we call the warrants for redemption as described above, our management will have the option to require all holders that wish to exercise warrants to do so on a “cashless basis.” In such event, each holder would pay the exercise price by surrendering the warrants for that number of shares of Class A common stock equal to the quotient obtained by dividing (x) the product of the number of shares of Class A common stock underlying the warrants, multiplied by the difference between the exercise price of the warrants and the “fair market value” (defined below) by (y) the fair market value. The “fair market value” for this purpose shall mean the average reported last sale price of the shares of Class A common stock for the 5 trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of warrants.

The warrants will be issued in registered form under a warrant agreement between Continental Stock Transfer & Trust Company, as warrant agent, and us. The warrant agreement provides that the terms of the warrants may be amended without the consent of any holder (i) to cure any ambiguity or correct any mistake, including to conform the provisions of the warrant agreement to the description of the terms of the warrants and the warrant agreement set forth in the final prospectus, or to cure, correct or supplement any defective provision, or (ii) to add or change any other provisions with respect to matters or questions arising under the warrant agreement as the parties to the warrant agreement may deem necessary or desirable and that the parties deem to not adversely affect the interests of the registered holders of the warrants. The warrant agreement requires the approval, by written consent or vote, of the holders of at least 50% of the then outstanding public warrants in order to make any change that adversely affects the interests of the registered holders.

The exercise price and number of shares of Class A common stock issuable on exercise of the warrants may be adjusted in certain circumstances including in the event of a stock dividend, extraordinary dividend or our recapitalization, reorganization, merger or consolidation. However, except as described below, the warrants will not be adjusted for issuances of shares of Class A common stock at a price below their respective exercise prices.

In addition, if (x) we issue additional shares of Class A common stock or equity-linked securities for capital raising purposes in connection with the closing of our initial business combination at a an issue price or effective issue price less than $9.20 per share of Class A common stock (“Newly Issued Price”) (of with such issue price or effective issue price to be determined in good faith by our board of directors, and in the case of any such issuance to our sponsor, initial stockholders, any anchor investors holding founder shares or their affiliates, without taking into account any founder shares held by them prior to such issuance), (y) the aggregate gross proceeds from such issuances represent more than 60% of the total equity proceeds, and interest thereon, available for the funding of our initial business

​

combination on the date of the consummation of our initial business combination (net of redemptions), and (z) the volume weighted average trading price of shares of our Class A common stock during the 20 trading day period starting on the trading day prior to the day on which we consummate our initial business combination (such price, the “Market Value”) is below $9.20 per share, then the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the greater of (i) the Market Value or (ii) the Newly Issued Price, and the $18.00 per share redemption trigger price of the warrants will be adjusted (to the nearest cent) to be equal to 180% of the greater of (i) the Market Value or (ii) the Newly Issued Price.

The warrants 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, by certified or official bank check payable to us, for the number of warrants being exercised. The warrant holders do not have the rights or privileges of holders of shares of Class A common stock and any voting rights until they exercise their warrants and receive shares of Class A common stock. After the issuance of shares of Class A common stock upon exercise of the warrants, each holder will be entitled to one vote for each share held of record on all matters to be voted on by stockholders.

Warrant holders may elect to be subject to a restriction on the exercise of their warrants such that an electing warrant holder would not be able to exercise their warrants to the extent that, after giving effect to such exercise, such holder would beneficially own in excess of 9.8% of the shares of Class A common stock outstanding.

No fractional shares will be issued upon exercise of the warrants. If, upon exercise of the warrants, a holder would be entitled to receive a fractional interest in a share, we will, upon exercise, round up to the nearest whole number the number of shares of Class A common stock to be issued to the warrant holder.

We have agreed that, subject to applicable law, any action, proceeding or claim against us arising out of or relating in any way to the warrant agreement, including under the Securities Act, will be brought and enforced in the courts of the State of New York or the United States District Court for the Southern District of New York, and we irrevocably submit to such jurisdiction, which jurisdiction will be the exclusive forum for any such action, proceeding or claim. See “Risk Factors—Our warrant agreement will designate the courts of the State of New York or the United States District Court for the Southern District of New York as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by holders of our warrants, which could limit the ability of warrant holders to obtain a favorable judicial forum for disputes with our company.” This exclusive forum provision shall not apply to suits brought to enforce a duty or liability created by the Exchange Act, any other claim for which the federal district courts of the United States of America are the sole and exclusive forum.

In order to fund working capital deficiencies or finance transaction costs in connection with an intended initial business combination, our sponsor or an affiliate of our sponsor or certain of our officers and directors may loan us funds as may be required, although they are under no obligation to advance funds or invest in us. Up to $1,500,000 of such loans may be convertible into warrants of the post business combination entity at a price of $1.00 per warrant at the option of the lender. Such warrants would be identical to the private placement warrants.

Dividends

We have not paid any cash dividends on our shares of common stock to date and do not intend to pay cash dividends prior to the completion of our initial business combination. The payment of cash dividends in the future will be dependent upon our revenues and earnings, if any, capital requirements and general financial condition subsequent to completion of our initial business combination. The payment of any cash dividends subsequent to our initial business combination will be within the discretion of our board of directors at such time. In addition, our board of directors is not currently contemplating and does not anticipate declaring any stock dividends in the foreseeable future, except if we increase the size of this offering, in which case we will effect a capitalization or other appropriate mechanism immediately prior to the consummation of this offering in such amount as to maintain the number of founder shares at 20% of our issued and outstanding shares of common stock upon the consummation of this offering. Further, if we incur any indebtedness in connection with our initial business combination, our ability to declare dividends may be limited by restrictive covenants we may agree to in connection therewith.
