Description of the Companys securities

Exhibit 4.2

DESCRIPTION OF SECURITIES

As of December 31, 2021, Perception Capital Corp. II (“we,” “our,” “us” or the “company”) had the following three classes of securities registered under Section 12 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”): (i) its units, each consisting of one Class A ordinary share and one-half of one redeemable warrant, (ii) Class A ordinary shares, par value $0.0001 per share (the “Class A ordinary shares” or “public shares”), and (iii) redeemable public warrants, each whole public warrant exercisable for one Class A ordinary share at an exercise price of $11.50 (the “public warrants”). In addition, this Description of Securities also references the company’s Class B ordinary shares, par value $0.0001 per share (the “Class B ordinary shares” or “founder shares”), which are not registered pursuant to Section 12 of the Exchange Act but are convertible into Class A ordinary shares. The description of the Class B ordinary shares is included to assist in the description of the Class A ordinary shares. Unless the context otherwise requires, references to our “sponsor” are to Perception Capital Partners II LLC and references to our “initial shareholders” are to our sponsor and our independent directors that held our founder shares prior to our initial public offering (our “IPO”).

We are a Cayman Islands exempted company and our affairs are governed by our amended and restated memorandum and articles of association, the Companies Act and common law of the Cayman Islands. Pursuant to our amended and restated memorandum and articles of association (“M&AA”), we are authorized to issue 500,000,000 Class A ordinary shares, $0.0001 par value each, 50,000,000 Class B ordinary shares, $0.0001 par value each, and 5,000,000 undesignated preferred shares, $0.0001 par value each. The following description summarizes the material terms of our shares as set out more particularly in our M&AA. Because the below is only a summary, it may not contain all the information that is important to you.

Units

Each unit consists of one Class A ordinary share and one-half of one redeemable public warrant. Each whole public warrant entitles the holder thereof to purchase one Class A ordinary share at a price of $11.50 per share, subject to adjustment as described below. Pursuant to the warrant agreement that governs the warrants (the “warrant agreement”), a public warrant holder may exercise its public warrants only for a whole number of the company’s Class A ordinary shares. This means only a whole public warrant may be exercised at any given time by a public warrant holder.

Holders have the option 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 Class A ordinary shares and public 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 public warrants will be issued upon separation of the units and only whole public warrants will trade.

Ordinary Shares

Class A ordinary shareholders and Class B ordinary shareholders of record are entitled to one vote for each share held on all matters to be voted on by shareholders and vote together as a single class, except as required by law; provided, that, prior to our initial business combination, holders of our Class B ordinary shares will have the right to appoint all of our directors and remove members of the board of directors for any reason, and holders of our Class A ordinary shares will not be entitled to vote on the appointment of directors during such time. These provisions of our M&AA may only be amended by a special resolution passed by a majority of at least 90% of our ordinary shares attending and voting in a general meeting. Unless specified in the Companies Act, our M&AA or applicable stock exchange rules, the affirmative vote of a majority of our ordinary shares that are voted is required to approve any such matter voted on by our shareholders (other than the appointment or removal of directors prior to our initial business combination), and, prior to our initial business combination, the affirmative vote of a majority of our founder shares is required to approve the appointment or removal of directors. Approval of certain actions will require a special resolution under Cayman Islands law and pursuant to our M&AA; such actions include amending our M&AA and approving a statutory merger or consolidation with another company. Directors are appointed for a term of two years. There is no cumulative voting with respect to the appointment of directors, with the result that the holders of more than 50% of the founder shares voted for the appointment of directors can appoint all of the directors prior to our initial business combination. Our shareholders are entitled to receive ratable dividends when, as and if declared by the board of directors out of funds legally available therefor.

Because our M&AA authorize the issuance of up to 500,000,000 Class A ordinary shares, 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 Class A ordinary shares which we are authorized to issue at the same time as our shareholders vote on the business combination to the extent we seek shareholder approval in connection with our initial business combination.

In accordance with the Nasdaq corporate governance requirements, we are not required to hold an annual general meeting until one year after our first fiscal year end following our listing on Nasdaq. There is no requirement under the Companies Act for us to hold annual or extraordinary general meetings to appoint directors. We may not hold an annual general meeting prior to the consummation of our initial business combination.

We will provide our public shareholders with the opportunity to redeem all or a portion of their public 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 calculated as of two business days prior to the consummation of our initial business combination, including interest earned on the funds held in the trust account and not previously released to us to pay our taxes (which interest shall be net of taxes payable), divided by the number of then issued and outstanding public shares, subject to the limitations described herein. 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 rights will include the requirement that a beneficial owner must identify itself in order to validly redeem its shares. Our initial shareholders, directors and officers 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

4

public shares held by them in connection with the completion of our initial business combination or certain amendments to our M&AA (the “letter agreement”). Permitted transferees of our initial shareholders, directors or officers will be subject to the same obligations.

Unlike some blank check companies that hold shareholder 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 shareholder vote is not required by applicable law or stock exchange listing requirements and we do not decide to hold a shareholder vote for business or other reasons, we will, pursuant to our M&AA, conduct the 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 M&AA require 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 shareholder approval of the transaction is required by applicable law or stock exchange listing requirements, or we decide to obtain shareholder approval for business or other reasons, we will, like some 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 shareholder approval, we will complete our initial business combination only if we receive an ordinary resolution under Cayman Islands law, which requires the affirmative vote of holders of a majority of ordinary shares who attend and vote at a general meeting of the company. However, the participation of our sponsor, directors, officers, advisors or any of their respective affiliates in privately-negotiated transactions, if any, could result in the approval of our initial business combination even if a majority of our public shareholders vote, or indicate their intention to vote, against such business combination. For purposes of seeking approval of the majority of our issued and outstanding ordinary shares, non-votes will have no effect on the approval of our initial business combination once a quorum is obtained. A quorum for such meeting will be present if the holders of one-third of our issued and outstanding ordinary shares entitled to vote at the meeting are represented in person or by proxy. Our sponsor, officers and directors will count toward this quorum and, pursuant to the letter agreement, our sponsor, officers and directors have agreed to vote any founder shares and public shares held by them (including any shares purchased in this offering or in open market and privately-negotiated transactions) in favor of our initial business combination. We intend to give 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 the voting agreements of our initial shareholders, may make it more likely that we will consummate our initial business combination.

If we seek shareholder 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 M&AA provide that a public shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder is acting in concert or as a “group” (as defined under Section 13 of the Exchange Act), will be restricted from redeeming its shares with respect to more than an aggregate of 15% of the ordinary shares sold in the IPO, which we refer to as the “excess shares,” without our prior consent. However, we would not be restricting our shareholders’ ability to vote all of their shares (including excess shares) for or against our initial business combination. Our shareholders’ inability to redeem the excess shares will reduce their influence over our ability

4

to complete our initial business combination, and such shareholders could suffer a material loss in their investment if they sell such excess shares on the open market. Additionally, such shareholders will not receive redemption distributions with respect to the excess shares if we complete the business combination. As a result, such shareholders will continue to hold that number of shares exceeding 15% and, in order to dispose such shares would be required to sell their shares in open market transactions, potentially at a loss.

If we seek shareholder approval in connection with our initial business combination, our initial shareholders have agreed (and their 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 in favor of our initial business combination. Our directors and officers have also entered into the letter agreement, imposing similar obligations on them with respect to public shares acquired by them, if any. Additionally, each public shareholder 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 M&AA, if we have not completed our initial business combination within 12 months (or up to 18 months if the sponsor exercises its extension options) from the closing of the IPO, we will (1) cease all operations except for the purpose of winding up, (2) as promptly as reasonably possible but not more than 10 business days thereafter, 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 earned on the funds held in the trust account and not previously released to us to pay our taxes (less up to $100,000 of interest to pay dissolution expenses and which interest shall be net of taxes payable), divided by the number of then issued and outstanding public shares, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidating distributions, if any), and (3) as promptly as reasonably possible following such redemption, subject to the approval of our remaining shareholders and our board of directors, liquidate and dissolve, subject in each case to our obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. Our initial shareholders 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 their founder shares if we fail to complete our initial business combination within 12 months (or up to 18 months if the sponsor exercises its extension options) from the closing of the IPO or during any extended time that we have to consummate a business combination beyond 18 months as a result of a shareholder vote to amend our M&AA (an “extension period”). However, if our initial shareholders, directors or officers acquire public shares, 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 the prescribed time period.

In the event of a liquidation, dissolution or winding up of the company after a business combination, our shareholders at such time will be 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 shares, if any, having preference over the ordinary shares. Our shareholders have no preemptive or other subscription rights. There are no sinking fund provisions applicable to the ordinary shares, except that we will provide our shareholders with the opportunity to redeem their public shares for cash equal to their pro rata share of the aggregate amount then on deposit in the trust account, including interest earned on the funds held in the trust account and not previously

4

released to us to pay our taxes (which interest shall be net of taxes payable), upon the completion of our initial business combination, subject to the limitations described herein.

Founder Shares

The founder shares are designated as Class B ordinary shares and are identical to the Class A ordinary shares included in the units sold in the IPO, and holders of founder shares have the same shareholder rights as public shareholders, 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 shareholders, 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 shareholder vote to amend our M&AA (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 12 months (or up to 18 months if the sponsor exercises its extension options) from the closing of the IPO or during any extension period, or (B) with respect to any other provision relating to shareholders’ 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 12 months (or up to 18 months if the sponsor exercises its extension options) from the closing of the IPO (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 our Class A ordinary shares 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. If we submit our initial business combination to our public shareholders for a vote, our initial shareholders have agreed (and their 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 in favor of our initial business combination.

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

4

completion of the IPO plus all Class A ordinary shares 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 our Class A ordinary shares issued in a financing transaction in connection with our initial business combination, including but not limited to a private placement of equity or debt.

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 our Class A ordinary shares equals or exceeds $12.00 per share (as adjusted for share sub-divisions, share 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, share exchange, reorganization or other similar transaction that results in all of our public shareholders having the right to exchange their ordinary shares for cash, securities or other property.

Register of Members

Under Cayman Islands law, we must keep a register of members and there shall be entered therein:

Under Cayman Islands law, the register of members of our company is prima facie evidence of the matters set out therein (i.e., the register of members will raise a presumption of fact on the matters referred to above unless rebutted) and a member registered in the register of members shall be deemed as a matter of Cayman Islands law to have legal title to the shares as set against its name in the register of members. Upon the closing of the IPO, the register of members was updated to reflect the issue of shares by us.

The shareholders recorded in the register of members shall be deemed to have legal title to the shares set against their name. However, there are certain limited circumstances where an application may be made to a Cayman Islands court for a determination on whether the register of members reflects the correct legal position. Further, the Cayman Islands court has the power to order that the register of members maintained by a company should be rectified where it considers that the register of members does not reflect the correct legal position. If an application for an order

4

for rectification of the register of members were made in respect of our ordinary shares, then the validity of such shares may be subject to re-examination by a Cayman Islands court.

Redeemable Warrants

Public Shareholders’ Warrants

Each whole public warrant entitles the registered holder to purchase one Class A ordinary share at a price of $11.50 per share, subject to adjustment as discussed below, at any time commencing 30 days after the completion of our initial business combination, except as described below. Pursuant to the warrant agreement, a public warrant holder may exercise its warrants only for a whole number of Class A ordinary shares. This means only a whole public warrant may be exercised at a given time by a public warrant holder. No fractional public warrants will be issued upon separation of the units and only whole public warrants will trade. The public warrants will expire five years after the completion of our initial business combination, at 5:00 p.m., New York City time, or earlier upon redemption or liquidation.

We will not be obligated to deliver any Class A ordinary shares pursuant to the exercise of a public warrant and will have no obligation to settle such public warrant exercise unless a registration statement under the Securities Act covering the issuance of the Class A ordinary shares issuable upon exercise of the public warrants is then effective and a current prospectus relating thereto is current, subject to our satisfying our obligations described below with respect to registration, or a valid exemption from registration is available, including in connection with a cashless exercise permitted as described. Except as described below, no public warrant will be exercisable for cash or on a cashless basis, and we will not be obligated to issue any shares to holders seeking to exercise their public warrants, unless the issuance of the shares upon such exercise is registered or qualified under the securities laws of the state of the exercising holder, or an exemption is available. In the event that the conditions in the two immediately preceding sentences are not satisfied with respect to a public warrant, the holder of such public warrant will not be entitled to exercise such warrant and such public warrant may have no value and expire worthless. In the event that a registration statement is not effective for the exercised public warrants, the purchaser of a unit containing such public warrant will have paid the full purchase price for the unit solely for the Class A ordinary share underlying such unit.

While we have registered the Class A ordinary shares issuable upon exercise of the public warrants under the Securities Act as part of the registration statement of which the prospectus related to the IPO forms a part, we do not plan on keeping a prospectus current until required to pursuant to the warrant agreement. We have agreed that as soon as practicable, but in no event later than 15 business days, after the closing of our initial business combination, we will use our commercially reasonable efforts to file with the SEC a post-effective amendment to the registration statement of which the prospectus related to the IPO forms a part or a new registration statement covering the issuance, under the Securities Act, of the Class A ordinary shares issuable upon exercise of the public warrants, and we will use our commercially reasonable efforts to cause the same to become effective within 60 business days after the closing of our initial business combination and to maintain the effectiveness of such post-effective amendment or registration statement, and a current prospectus relating thereto, until the expiration of the public warrants in accordance with the provisions of the warrant agreement.

4

If a registration statement covering the Class A ordinary shares issuable upon exercise of the public warrants does not become effective within 60 business days after the closing of our initial business combination, holders of public warrants will have the right, during any period thereafter when there is no such effective registration statement, to exercise the public warrants on a cashless basis. Additionally, if, at the time that a public warrant is exercised, our Class A ordinary shares are not listed on a national securities exchange such that they satisfy 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 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 elect, we will not be required to file or maintain in effect a registration statement, but will use our commercially reasonable efforts to register or qualify the shares under applicable blue sky laws to the extent an exemption is not available.

In the event of a cashless exercise pursuant to the preceding paragraph, each holder would pay the exercise price by surrendering the public warrants for that number of Class A ordinary shares equal to the quotient obtained by dividing (x) the product of the number of Class A ordinary shares underlying the warrants, multiplied by the excess of the “fair market value” (defined below) less the exercise price of the warrants by (y) the fair market value. The “fair market value” as used in the preceding sentence shall mean the volume weighted average price of the Class A ordinary shares for the 10 trading days ending on the trading day prior to the date on which the notice of exercise is received by the warrant agent.

Redemption of public warrants.    Once the public warrants become exercisable, we may redeem the outstanding public warrants:

We will not redeem the public warrants as described above unless a registration statement under the Securities Act covering the issuance of the Class A ordinary shares issuable upon exercise of the public warrants is then effective and a current prospectus relating to those Class A ordinary shares is available throughout the 30-day redemption period or we have elected to require the exercise of the public warrants on a cashless basis as described below. If and when the public warrants become redeemable by us, we may exercise our redemption right even if we are unable to register or qualify the underlying securities for sale under all applicable state securities laws. If we call the warrants for redemption as described in this paragraph, our management will have the option to require any holder that wishes to exercise his, her or its warrant following the notice of

4

redemption to do so on a cashless basis. In the case of such a cashless exercise, each holder would pay the exercise price by surrendering the public warrants for that number of Class A ordinary shares equal to the quotient obtained by dividing (x) the product of the number of Class A ordinary shares underlying the warrants, multiplied by the excess of the “fair market value” less the exercise price of the warrants by (y) the fair market value. The “fair market value” as used in the preceding sentence shall mean the volume weighted average price of the Class A ordinary shares for the 10 trading days ending on the trading day prior to the date on which the notice of redemption is sent to the holders of the public warrants. If our management takes advantage of this option, the notice of redemption will contain the information necessary to calculate the number of Class A ordinary shares to be received upon exercise of the warrants, including the “fair market value” in such case.

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 public warrant exercise price. If the foregoing conditions are satisfied and we issue a notice of redemption of the public warrants, each public warrant holder will be entitled to exercise his, her or its public warrant prior to the scheduled redemption date. However, the price of the Class A ordinary shares may fall below the $18.00 redemption trigger price (as adjusted for adjustments to the number of shares issuable upon exercise or the exercise price of a public warrant as described below) as well as the $11.50 (for whole shares) public warrant exercise price after the redemption notice is issued.

Redemption procedures.    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 public 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 of 9.8% (or such other amount as a holder may specify) of the Class A ordinary shares issued and outstanding immediately after giving effect to such exercise.

Anti-dilution Adjustments.    If the number of issued and outstanding Class A ordinary shares is increased by a capitalization or share dividend payable in Class A ordinary shares, or by a split-up of Class A ordinary shares or other similar event, then, on the effective date of such capitalization or share dividend, split-up or similar event, the number of Class A ordinary shares issuable on exercise of each public warrant will be increased in proportion to such increase in the issued and outstanding Class A ordinary shares. A rights offering made to all or substantially all holders of Class A ordinary shares entitling holders to purchase Class A ordinary shares at a price less than the “historical fair market value” (as defined below) will be deemed a share dividend of a number of Class A ordinary shares equal to the product of (1) the number of Class A ordinary shares 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 Class A ordinary shares) and (2) one minus the quotient of (x) the price per Class A ordinary share paid in such rights offering and (y) the historical fair market value. For these purposes, (1) if the rights offering is for securities convertible into or exercisable for Class A ordinary shares, in determining the price payable for Class A ordinary shares, there will be taken into account any consideration received for such rights, as well as any additional amount payable upon exercise or conversion and (2) “historical fair market value” means the volume weighted average price of Class A ordinary shares during the 10 trading day period ending on the trading day prior to the first date on which the Class A ordinary shares trade on the applicable exchange or in the applicable market, regular way, without the right to receive such rights.

4

In addition, if we, at any time while the public warrants are outstanding and unexpired, pay to all or substantially all of the holders of Class A ordinary shares a dividend or make a distribution in cash, securities or other assets to the holders of Class A ordinary shares on account of such Class A ordinary shares (or other securities into which the public warrants are convertible), other than (a) as described above, (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 Class A ordinary shares during the 365-day period ending on the date of declaration of such dividend or distribution does not exceed $0.50 (as adjusted for share sub-divisions, share dividends, rights issuances, consolidations, reorganizations, recapitalizations and other similar transactions) but only with respect to the amount of the aggregate cash dividends or cash distributions equal to or less than $0.50 per share, (c) to satisfy the redemption rights of the holders of Class A ordinary shares in connection with a proposed initial business combination, (d) to satisfy the redemption rights of the holders of Class A ordinary shares in connection with a shareholder vote to amend our M&AA (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 12 months (or up to 18 months if the sponsor exercises its extension options) from the closing of the IPO or (B) with respect to any other provision relating to shareholders’ rights or pre-initial business combination activity, or (e) in connection with the redemption of our public shares upon our failure to complete our initial business combination, then the public warrant exercise price will be decreased, effective immediately after the effective date of such event, by the amount of cash and/or the fair market value of any securities or other assets paid on each Class A ordinary share in respect of such event.

If the number of issued and outstanding Class A ordinary shares is decreased by a consolidation, combination, reverse share sub-division or reclassification of Class A ordinary shares or other similar event, then, on the effective date of such consolidation, combination, reverse share sub-division, reclassification or similar event, the number of Class A ordinary shares issuable on exercise of each public warrant will be decreased in proportion to such decrease in issued and outstanding Class A ordinary shares.

Whenever the number of Class A ordinary shares purchasable upon the exercise of the public warrants is adjusted, as described above, the public warrant exercise price will be adjusted by multiplying the public warrant exercise price immediately prior to such adjustment by a fraction (x) the numerator of which will be the number of Class A ordinary shares purchasable upon the exercise of the public warrants immediately prior to such adjustment and (y) the denominator of which will be the number of Class A ordinary shares so purchasable immediately thereafter.

In addition, if (x) we issue additional ordinary shares or equity-linked securities for capital raising purposes in connection with the closing of our initial business combination at an issue price or effective issue price of less than $9.20 per ordinary share (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 or its affiliates, without taking into account any founder shares held by our sponsor or such affiliates, as applicable, prior to such issuance) (the “Newly Issued Price”), (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 completion of our initial business combination (net of redemptions), and (z) the volume weighted average trading price of our Class A ordinary shares during the 20 trading day period

4

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, the exercise price of the public warrants will be adjusted (to the nearest cent) to be equal to 115% of the higher of the Market Value and the Newly Issued Price, the $18.00 per share redemption trigger price described above will be adjusted (to the nearest cent) to be equal to 180% of the higher of the Market Value and the Newly Issued Price.

In case of any reclassification or reorganization of the issued and outstanding Class A ordinary shares (other than those described above or that solely affects the par value of such Class A ordinary shares), or in the case of a merger or consolidation of us with or into another corporation (other than a merger or consolidation in which we are the continuing corporation and that does not result in any reclassification or reorganization of our issued and outstanding Class A ordinary shares), 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 in connection with which we are dissolved, the holders of the 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 our Class A ordinary shares immediately theretofore purchasable and receivable upon the exercise of the rights represented thereby, the kind and amount of shares, stock or other equity 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 merger or consolidation, 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 merger or consolidation that affirmatively make such election, and if a tender, exchange or redemption offer has been made to and accepted by such holders (other than a tender, exchange or redemption offer made by the company in connection with redemption rights held by shareholders of the company as provided for in the company’s M&AA or as a result of the redemption of Class A ordinary shares by the company if a proposed initial business combination is presented to the shareholders of the company for approval) under circumstances in which, upon completion of such tender or exchange offer, the maker thereof, together with members of any group (within the meaning of Rule 13d-5(b)(1) under the Exchange Act) of which such maker is a part, and together with any affiliate or associate of such maker (within the meaning of Rule 12b-2 under the Exchange Act) and any members of any such group of which any such affiliate or associate is a part, own beneficially (within the meaning of Rule 13d-3 under the Exchange Act) (x) if prior to the initial business combination, more than 50% of the issued and outstanding ordinary shares or (y) if on or after the initial business combination, securities representing more than 50% of the aggregate voting power represented by the issued and outstanding shares of the company, the holder of a warrant will be entitled to receive the highest amount of cash, securities or other property to which such holder would actually have been entitled as a shareholder if such warrant holder had exercised the warrant prior to the expiration of such tender or exchange offer, accepted such offer and all of the Class A ordinary shares held by such holder had been purchased pursuant to such tender or exchange offer, subject to adjustment (from and after the consummation of such tender or exchange offer) as nearly equivalent as possible to the adjustments provided for in the warrant agreement. Additionally, if less than 70% of the consideration receivable by the holders of Class A ordinary shares in such a transaction is

4

payable in the form of ordinary shares 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 warrant properly exercises the public warrant within 30 days following public disclosure of such transaction, the public warrant exercise price will be reduced as specified in the warrant agreement based on the per share consideration minus Black-Scholes Warrant Value (as defined in the warrant agreement) of the public warrant.

The public warrants are issued in registered form under the warrant agreement between Continental Stock Transfer & Trust Company, as warrant agent, and us. You should review a copy of the warrant agreement for a complete description of the terms and conditions applicable to the public warrants. The warrant agreement provides that (a) the terms of the public warrants may be amended without the consent of any holder for the purpose of (i) curing any ambiguity or correcting any mistake, including to conform the provisions of the warrant agreement to the description of the terms of the public warrants and the warrant agreement set forth in the prospectus related to the IPO, or defective provision (ii) removing or reducing the Company’s ability to redeem the public warrants and, if applicable, a corresponding amendment to the Company’s ability to redeem the private placement warrants or (iii) adding or changing any 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 rights of the registered holders of the public warrants under the warrant agreement in any material respect, (b) the terms of the warrants may be amended with the vote or written consent of at least 50% of the then outstanding public warrants and private placement warrants, voting together as a single class, to allow for the warrants to be classified as equity in our financial statements and (c) all other modifications or amendments to the warrant agreement with respect to the public warrants require the vote or written consent of at least 50% of the then outstanding public warrants and with respect to the private placement warrants require the vote of holders of at least 50% of the then outstanding private placement warrants.

The public warrant holders do not have the rights or privileges of holders of Class A ordinary shares and any voting rights until they exercise their public warrants and receive Class A ordinary shares. After the issuance of Class A ordinary shares 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 shareholders.

No fractional public warrants will be issued upon separation of the units and only whole public warrants will trade.

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 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. This provision applies to claims under the Securities Act but does not apply to claims under the Exchange Act or any claim for which the federal district courts of the United States of America are the sole and exclusive forum.

Our Transfer Agent and Warrant Agent

The transfer agent for our ordinary shares and warrant agent for our warrants is Continental Stock Transfer & Trust Company. We have agreed to indemnify Continental Stock Transfer & Trust Company in its roles as transfer agent and warrant agent, its agents and each of its shareholders, directors, officers and employees against all liabilities, including judgments, costs and reasonable counsel fees that may arise out of acts performed or omitted for its activities in that capacity, except for any liability due to any gross negligence, willful misconduct or bad faith of the indemnified person or entity.

Certain Differences in Corporate Law

Cayman Islands companies are governed by the Companies Act. The Companies Act is modeled on English Law but does not follow recent English Law statutory enactments, and differs from laws applicable to United States corporations and their shareholders. Set forth below is a summary of the material differences between the provisions of the Companies Act applicable to us and the laws applicable to companies incorporated in the United States and their shareholders.

Mergers and Similar Arrangements.    In certain circumstances, the Companies Act allows for mergers or consolidations between two Cayman Islands companies, or between a Cayman Islands exempted company and a company incorporated in another jurisdiction (provided that is facilitated by the laws of that other jurisdiction).

Where the merger or consolidation is between two Cayman Islands companies, the directors of each company must approve a written plan of merger or consolidation containing certain prescribed information. That plan of merger or consolidation must then be authorized by either (a) a special resolution (usually a majority of 66⅔% in value who attend and vote at a general meeting) of the shareholders of each company; or (b) such other authorization, if any, as may be specified in such constituent company’s articles of association. No shareholder resolution is required for a merger between a parent company (i.e., a company that owns at least 90% of the issued shares of each class in a subsidiary company) and its subsidiary company. The consent of each holder of a fixed or floating security interest of a constituent company must be obtained, unless the court waives such requirement. If the Cayman Islands Registrar of Companies is satisfied that the requirements of the Companies Act (which includes certain other formalities) have been complied with, the Registrar of Companies will register the plan of merger or consolidation.

Where the merger or consolidation involves a foreign company, the procedure is similar, save that with respect to the foreign company, the directors of the Cayman Islands exempted company are required to make a declaration to the effect that, having made due enquiry, they are of the opinion that the requirements set out below have been met: (1) that the merger or consolidation is permitted or not prohibited by the constitutional documents of the foreign company and by the laws of the jurisdiction in which the foreign company is incorporated, and that those laws and any requirements of those constitutional documents have been or will be complied with; (2) that no petition or other similar proceeding has been filed and remains outstanding or order made or resolution adopted to wind up or liquidate the foreign company in any jurisdictions; (3) that no receiver, trustee, administrator or other similar person has been

4

appointed in any jurisdiction and is acting in respect of the foreign company, its affairs or its property or any part thereof; and (4) that no scheme, order, compromise or other similar arrangement has been entered into or made in any jurisdiction whereby the rights of creditors of the foreign company are and continue to be suspended or restricted.

Where the surviving company is the Cayman Islands exempted company, the directors of the Cayman Islands exempted company are further required to make a declaration to the effect that, having made due enquiry, they are of the opinion that the requirements set out below have been met: (1) that the foreign company is able to pay its debts as they fall due and that the merger or consolidated is bona fide and not intended to defraud unsecured creditors of the foreign company; (2) that in respect of the transfer of any security interest granted by the foreign company to the surviving or consolidated company (a) consent or approval to the transfer has been obtained, released or waived; (b) the transfer is permitted by and has been approved in accordance with the constitutional documents of the foreign company; and (c) the laws of the jurisdiction of the foreign company with respect to the transfer have been or will be complied with; (3) that the foreign company will, upon the merger or consolidation becoming effective, cease to be incorporated, registered or exist under the laws of the relevant foreign jurisdiction; and (4) that there is no other reason why it would be against the public interest to permit the merger or consolidation.

Where the above procedures are adopted, the Companies Act provides for a right of dissenting shareholders to be paid a payment of the fair value of his or her shares upon their dissenting to the merger or consolidation if they follow a prescribed procedure. In essence, that procedure is as follows: (a) the shareholder must give his or her written objection to the merger or consolidation to the constituent company before the vote on the merger or consolidation, including a statement that the shareholder proposes to demand payment for his or her shares if the merger or consolidation is authorized by the vote; (b) within 20 days following the date on which the merger or consolidation is approved by the shareholders, the constituent company must give written notice to each shareholder who made a written objection; (c) a shareholder must within 20 days following receipt of such notice from the constituent company, give the constituent company a written notice of his or her intention to dissent including, among other details, a demand for payment of the fair value of his or her shares; (d) within seven days following the date of the expiration of the period set out in paragraph (b) above or seven days following the date on which the plan of merger or consolidation is filed, whichever is later, the constituent company, the surviving company or the consolidated company must make a written offer to each dissenting shareholder to purchase his or her shares at a price that the company determines is the fair value and if the company and the shareholder agrees to the price within 30 days following the date on which the offer was made, the company must pay the shareholder such amount; and (e) if the company and the shareholder fails to agree to a price within such 30-day period, within 20 days following the date on which such 30-day period expires, the company (and any dissenting shareholder) must file a petition with the Cayman Islands Grand Court to determine the fair value and such petition must be accompanied by a list of the names and addresses of the dissenting shareholders with whom agreements as to the fair value of their shares have not been reached by the company. At the hearing of that petition, the court has the power to determine the fair value of the shares together with a fair rate of interest, if any, to be paid by the company upon the amount determined to be the fair value. Any dissenting shareholder whose name appears on the list filed by the company may participate fully in all proceedings until the determination of fair value is reached. These rights of a dissenting shareholder are not to be available in certain circumstances, for example, to dissenters holding

4

shares of any class in respect of which an open market exists on a recognized stock exchange or recognized interdealer quotation system at the relevant date or where the consideration for such shares to be contributed are shares of any company listed on a national securities exchange or shares of the surviving or consolidated company.

Moreover, Cayman Islands law also has separate statutory provisions that facilitate the reconstruction or amalgamation of companies in certain circumstances, such schemes of arrangement will generally be more suited for complex mergers or other transactions involving widely held companies, commonly referred to in the Cayman Islands as a “scheme of arrangement” which may be tantamount to a merger. In the event that a merger was sought pursuant to a scheme of arrangement (the procedures of which are more rigorous and take longer to complete than the procedures typically required to consummate a merger in the United States), the arrangement in question must be approved by a majority in number of each class of shareholders and creditors with whom the arrangement is to be made and who must in addition represent three-fourths in value of each such class of shareholders or creditors, as the case may be, that are present and voting either in person or by proxy at a meeting summoned for that purpose. The convening of the meetings and subsequently the terms of the arrangement must be sanctioned by the Grand Court of the Cayman Islands. While a dissenting shareholder would have the right to express to the court the view that the transaction should not be approved, the court can be expected to approve the arrangement if it is satisfied that:

If a scheme of arrangement or takeover offer (as described below) is approved, any dissenting shareholder would have no rights comparable to appraisal rights, which would otherwise ordinarily be available to dissenting shareholders of U.S. corporations, providing rights to receive payment in cash for the judicially determined value of the shares.

Squeeze-out Provisions.    When a takeover offer is made and accepted by holders of 90% of the shares to whom the offer relates within four months, the offeror may, within a two-month period, require the holders of the remaining shares to transfer such shares on the terms of the offer. An objection can be made to the Grand Court of the Cayman Islands, but this is unlikely to succeed unless there is evidence of fraud, bad faith, collusion or inequitable treatment of the shareholders.

Further, transactions similar to a merger, reconstruction and/or an amalgamation may in some circumstances be achieved through other means to these statutory provisions, such as a share capital exchange, asset acquisition or control, through contractual arrangements, of an operating business.

Shareholders’ Suits.    Our Cayman Islands legal counsel, is not aware of any reported class action having been brought in a Cayman Islands court. Derivative actions have been brought in

4

the Cayman Islands courts, and the Cayman Islands courts have confirmed the availability of such actions. In most cases, we will be the proper plaintiff in any claim based on a breach of duty owed to us, and a claim against (for example) our directors or officers usually may not be brought by a shareholder. However, based both on Cayman Islands authorities and on English authorities, which would in all likelihood be of persuasive authority and applied by a court in the Cayman Islands, exceptions to the foregoing principle apply in circumstances in which:

A shareholder may have a direct right of action against us where the individual rights of that shareholder have been infringed or are about to be infringed.

Enforcement of Civil Liabilities.    The Cayman Islands has a different body of securities laws as compared to the United States and provides less protection to investors. Additionally, Cayman Islands companies may not have standing to sue before the federal courts of the United States.

We have been advised by our Cayman Islands legal counsel that the courts of the Cayman Islands are unlikely (1) to recognize or enforce against us judgments of courts of the United States predicated upon the civil liability provisions of the federal securities laws of the United States or any state and (2) in original actions brought in the Cayman Islands, to impose liabilities against us predicated upon the civil liability provisions of the federal securities laws of the United States or any state, so far as the liabilities imposed by those provisions are penal in nature. In those circumstances, although there is no statutory enforcement in the Cayman Islands of judgments obtained in the United States, the courts of the Cayman Islands will recognize and enforce a foreign money judgment of a foreign court of competent jurisdiction without retrial on the merits based on the principle that a judgment of a competent foreign court imposes upon the judgment debtor an obligation to pay the sum for which judgment has been given provided certain conditions are met. For a foreign judgment to be enforced in the Cayman Islands, such judgment must be final and conclusive and for a liquidated sum, and must not be in respect of taxes or a fine or penalty, inconsistent with a Cayman Islands judgment in respect of the same matter, impeachable on the grounds of fraud or obtained in a manner, and or be of a kind the enforcement of which is, contrary to natural justice or the public policy of the Cayman Islands (awards of punitive or multiple damages may well be held to be contrary to public policy). A Cayman Islands Court may stay enforcement proceedings if concurrent proceedings are being brought elsewhere.

Special Considerations for Exempted Companies.    We are an exempted company with limited liability under the Companies Act. The Companies Act distinguishes between ordinary resident companies and exempted companies. Any company that is registered in the Cayman Islands but conducts business mainly outside of the Cayman Islands may apply to be registered as an exempted company. The requirements for an exempted company are essentially the same as for an ordinary company except for the exemptions and privileges listed below:

4

“Limited liability” means that the liability of each shareholder is limited to the amount unpaid by the shareholder on the shares of the company (except in exceptional circumstances, such as involving fraud, the establishment of an agency relationship or an illegal or improper purpose or other circumstances in which a court may be prepared to pierce or lift the corporate veil).

Our Amended and Restated Memorandum and Articles of Association

Our M&AA contain certain requirements and restrictions that will apply to us until the completion of our initial business combination. These provisions (other than amendments relating to provisions governing the appointment or removal of directors prior to our initial business combination, which require the approval of a majority of at least 90% of our ordinary shares attending and voting in a general meeting) cannot be amended without a special resolution. As a matter of Cayman Islands law, a resolution is deemed to be a special resolution where it has been approved by either (1) holders of at least two-thirds (or any higher threshold specified in a company’s articles of association) of a company’s ordinary shares at a general meeting for which notice specifying the intention to propose the resolution as a special resolution has been given or (2) if so authorized by a company’s articles of association, by a unanimous written resolution of all of the company’s shareholders. Other than as described above, our M&AA provide that special resolutions must be approved either by holders of at least two-thirds of our ordinary shares who attend and vote at a general meeting (i.e., the lowest threshold permissible under Cayman Islands law), or by a unanimous written resolution of all of our shareholders.

Our initial shareholders may participate in any vote to amend our M&AA and will have the discretion to vote in any manner they choose. Specifically, our M&AA provide, among other things, that:

4

4

In addition, our M&AA provide that under no circumstances will we redeem our public shares in an amount that would cause our net tangible assets to be less than $5,000,001 following such redemptions.

The Companies Act permits a company incorporated in the Cayman Islands to amend its memorandum and articles of association with the approval of the holders of at least two-thirds of such company’s issued and outstanding ordinary shares attending and voting at a general meeting. A company’s articles of association may specify that the approval of a higher majority is required but, provided the approval of the required majority is obtained, any Cayman Islands exempted company may amend its memorandum and articles of association regardless of whether its memorandum and articles of association provide otherwise. Accordingly, although we could amend any of the provisions relating to our structure and business plan which are contained in our M&AA, we view all of these provisions as binding obligations to our shareholders and neither we, nor our directors or officers, will take any action to amend or waive any of these provisions unless we provide dissenting public shareholders with the opportunity to redeem their public shares.

Anti-Money Laundering — Cayman Islands

If any person resident in the Cayman Islands knows or suspects or has reasonable grounds for knowing or suspecting that another person is engaged in criminal conduct or money laundering or is involved with terrorism or terrorist financing and property and the information for that knowledge or suspicion came to their attention in the course of business in the regulated sector, or other trade, profession, business or employment, the person will be required to report such knowledge or suspicion to (i) the Financial Reporting Authority of the Cayman Islands, pursuant to the Proceeds of Crime Act (As Revised) of the Cayman Islands if the disclosure relates to criminal conduct or money laundering or (ii) a police officer of the rank of constable or higher, or the Financial Reporting Authority, pursuant to the Terrorism Act (As Revised) of the Cayman Islands, if the disclosure relates to involvement with terrorism or terrorist financing and property. Such a report shall not be treated as a breach of confidence or of any restriction upon the disclosure of information imposed by any enactment or otherwise.

We have certain duties under the Data Protection Act (As Revised) of the Cayman Islands (the “Data Protection Act”) based on internationally accepted principles of data privacy.

In this subsection, “we”, “us,” “our” and the “Company” refers to Perception Capital Corp. II or our affiliates and/or delegates, except where the context requires otherwise.
