Description of the Companys securities

Exhibit 4.2

DESCRIPTION OF SECURITIES

As of December 31, 2021, Arbor Rapha Capital Bioholdings Corp. I, a Delaware corporation (“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 share of Class A common stock and one-third of one redeemable warrant, (ii) Class A common stock, par value $0.0001 per share, and (iii) redeemable warrants, each whole warrant exercisable for one share of Class A common stock at an exercise price of $11.50.  In addition, this Description of Securities also references the company’s Class B common stock, par value $0.0001 per share (the “Class B common stock” or “founder shares”), which are not registered pursuant to Section 12 of the Exchange Act but are convertible into Class A common stock.  The description of the Class B common stock is included to assist in the description of the Class A common stock.  Unless the context otherwise requires, references to our “sponsor” are to Arbor Rapha Capital LLC and references to our “initial stockholder” are to our sponsor as it holds our founder shares prior to our initial public offering (our “IPO”).

Pursuant to our amended and restated certificate of incorporation, our authorized capital stock consists of 80,000,000 shares of Class A common stock, $0.0001 par value, 20,000,000 shares of Class B common stock, $0.0001 par value, and 1,000,000 shares of undesignated preferred stock, $0.0001 par value.  The number of authorized shares of any class of common stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority of the shares of common stock of the corporation entitled to vote thereon irrespective of the provisions of Section 242(b)(2) of the DGCL (or any successor provision thereto).  The following description summarizes the material terms of our capital stock.  Because it is only a summary, it may not contain all the information that is important to you.

Units

Each unit consists of one whole share of Class A common stock and one-third 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.  Pursuant to the warrant agreement that governs the warrants (the “warrant agreement”), a warrant holder may exercise its warrants only for a whole number of shares of Class A common stock.  This means that only a whole warrant may be exercised at any given time by a warrant holder.  No fractional warrants will be issued upon separation of the units and only whole warrants will trade.

Holders will 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 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.

Common Stock

Common stockholders of record are entitled to one vote for each share held on all matters to be voted on by stockholders.  Holders of the Class A common stock and holders of the Class B common stock will vote together as a single class on all matters submitted to a vote of our stockholders, except as required by law.  Unless specified in our amended and restated certificate of incorporation or bylaws, or as required by applicable provisions of the DGCL or applicable 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.  There is no cumulative voting with respect to the election of directors, with the result that the holders of more than 50% of the shares voted for the election of directors can elect all of the 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.  Prior to our initial business combination, only holders of our founder shares will have the right to vote on the election of directors.  Holders of our public shares will not be entitled to vote on the election of directors during such time.  In addition, prior to the completion of an initial business combination, holders of a majority of our founder shares may remove a member of the board of directors for any reason.

Because our amended and restated certificate of incorporation authorizes the issuance of up to 80,000,000 shares of Class A common stock, if we were to enter into an initial business combination, we may (depending on the terms of such an initial business combination) be required to increase the number of shares of Class A common stock which we are

authorized to issue at the same time as our stockholders vote on our initial business combination to the extent we seek stockholder approval in connection with our initial business combination.

In accordance with the corporate governance requirements of The Nasdaq Global Market (“Nasdaq”), we are not required to hold an annual meeting until no later than one full 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 stockholders 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 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 franchise and income taxes, divided by the number of then 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 underwriter.  Our sponsor, 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.

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 law, if a stockholder vote is not required by law and we do not decide to hold a stockholder vote for business or other legal reasons, we will, pursuant to our amended and restated certificate of incorporation, 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 amended and restated certificate of incorporation will require these tender offer documents to contain substantially the same financial and other information about our 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 law, or we decide to obtain stockholder approval for business or other legal 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, we will complete our initial business combination only if a majority of the outstanding shares of common stock voted are voted in favor of our initial business combination.  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 their affiliates in privately negotiated transactions, 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 voted, 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 the voting agreements of our initial stockholders, 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 amended and restated certificate of incorporation will provide 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 its shares with respect to more than an aggregate of 15% of the shares of common stock sold in the IPO, 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 our initial 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, pursuant to the letter agreement our sponsor, officers and directors have agreed to vote their founder shares and any public shares purchased during or after the IPO (including in open market and privately negotiated transactions) in favor of our initial business combination.  Each public stockholder may elect to redeem its public shares irrespective of whether they vote for or against the proposed transaction (subject to the limitation described in the preceding paragraph).

Pursuant to our amended and restated certificate of incorporation, if we are unable to complete our initial business combination within 15 months from the closing of IPO or during any extension period, we will (i) cease all operations except for the purpose of winding up, (ii) 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 earned on the funds held in the trust account and not previously released to us to pay our franchise and income taxes (less 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 (iii) 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 sponsor, 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 15 months from the closing of the IPO or such later period approved by the company’s stockholders in accordance with the company’s amended and restated certificate of incorporation.  However, if our initial stockholders acquire public shares in or after the IPO, 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 an initial 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 then on deposit in the trust account, upon the completion of our initial business combination, subject to the limitations described herein.

Founder Shares

The founder shares are identical to the shares of Class A common stock included in the units sold in the IPO, and holders of founder shares have the same stockholder rights as public stockholders, except that (i) the founder shares are subject to certain transfer restrictions, as described in more detail below, (ii) our sponsor, officers and directors have entered into a letter agreement with us, pursuant to which they have agreed (A) 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, (B) to waive their redemption rights with respect to their founder shares and public shares in connection with a stockholder vote to approve an amendment to our amended and restated certificate of incorporation (x) 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 15 months from the closing of the IPO or (y) with respect to any other provision relating to stockholders’ rights or pre-initial business combination activity and (C) 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 15 months from the closing of the IPO 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 such time period, (iii) the founder shares are shares of our Class B common stock that will automatically convert into shares of our Class A common stock at the time of our initial business combination, or at any time prior thereto at the option of the holder, on a one-for-one basis, subject to adjustment as described herein, and (iv) are entitled to registration rights.  If we submit our initial business combination to our public stockholders for a vote, our sponsor, officers and directors have agreed pursuant to the letter agreement to vote

any founder shares held by them and any public shares purchased during or after the IPO (including in open market and privately negotiated transactions) in favor of our initial business combination.

The shares of Class B common stock will automatically convert into shares of Class A common stock at the time of our initial business combination on a one-for-one basis (subject to adjustment for stock splits, stock dividends, reorganizations, recapitalizations and the like), and subject to further adjustment as provided herein.  In the case that additional shares of Class A common stock, or equity-linked securities, are issued or deemed issued in excess of the amounts offered in the IPO and related to the closing of our initial business combination, the ratio at which shares of Class B common stock shall convert into shares of Class A common stock will be adjusted (unless the holders of a majority of the outstanding shares of Class B common stock agree to waive such adjustment with respect to any such issuance or deemed issuance) so that the number of shares of Class A common stock issuable upon conversion of all shares of Class B common stock will equal, in the aggregate, on an as-converted basis, 20% of the sum of the total number of all shares of common stock outstanding upon completion of the IPO plus all shares of 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, and any private placement-equivalent warrants issued to our sponsor or its affiliates upon conversion of loans made to us (including the sponsor loan)).  We cannot determine at this time whether a majority of the holders of our Class B common stock at the time of any future issuance would agree to waive such adjustment to the conversion ratio.  They may waive such adjustment due to (but not limited to) the following: (i) closing conditions which are part of the agreement for our initial business combination; (ii) negotiation with Class A stockholders on structuring an initial business combination; or (iii) negotiation with parties providing financing which would trigger the anti-dilution provisions of the Class B common stock.  If such adjustment is not waived, the issuance would not reduce the percentage ownership of holders of our Class B common stock, but would reduce the percentage ownership of holders of our Class A common stock.  If such adjustment is waived, the issuance would reduce the percentage ownership of holders of both classes of our common stock.  Holders of founder shares may also elect to convert their shares of Class B common stock into an equal number of shares of Class A common stock, subject to adjustment as provided above, at any time.  The term “equity-linked securities” refers to any debt or equity securities that are convertible, exercisable or exchangeable for shares of 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 could be “deemed issued” for purposes of the conversion rate adjustment if such shares are issuable upon the conversion or exercise of convertible securities, warrants or similar securities.

With certain limited exceptions, the founder shares are not transferable, assignable or salable (except to our officers and directors 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 or (B) subsequent to our initial business combination, (x) if the last sale price of our Class A common stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) 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 stockholders having the right to exchange their shares of common stock for cash, securities or other property.

Prior to our initial business combination, only holders of our founder shares will have the right to vote on the election of directors.  Holders of our public shares will not be entitled to vote on the election of directors during such time.  In addition, prior to the completion of an initial business combination, holders of a majority of our founder shares may remove a member of the board of directors for any reason.  These provisions of our amended and restated certificate of incorporation may only be amended by a resolution passed by a majority of our Class B common stock.  With respect to any other matter submitted to a vote of our stockholders, including any vote in connection with our initial business combination, except as required by law, holders of our founder shares and holders of our public shares will vote together as a single class, with each share entitling the holder to one vote.

Preferred Stock

Our amended and restated certificate of incorporation will provide that shares of preferred stock may be issued from time to time in one or more series.  Our board of directors will be 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 preferred stock with voting and other rights that could adversely affect the voting power and other rights of the holders of the common stock and could have anti-takeover effects.  The ability of our board of directors to issue

preferred stock without stockholder approval could have the effect of delaying, deferring or preventing a change of control of us or the removal of existing management.  We have no preferred stock outstanding at the date hereof.

Warrants

Redeemable Warrants

Public Stockholders’ Warrants

Each whole 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 30 days after the completion of our initial business combination and 12 months from the closing of the IPO, except as described below.  Pursuant to the warrant agreement, a warrant holder may exercise its warrants only for a whole number of shares of Class A common stock.  This means only a whole warrant may be exercised at a given time by a warrant holder.  No fractional warrants will be issued upon separation of the units and only whole warrants will trade.  The 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 common stock pursuant to the exercise of a warrant and will have no obligation to settle such warrant exercise unless a registration statement under the Securities Act covering the issuance of the shares of Class A common stock issuable upon exercise of the 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 a result of a notice of redemption described below under “Redemption of warrants when the price per share of Class A common stock equals or exceeds $18.00.”  No 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 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 warrant, the holder of such warrant will not be entitled to exercise such warrant and such warrant may have no value and expire worthless.  In the event that a registration statement is not effective for the exercised warrants, the purchaser of a unit containing such warrant will have paid the full purchase price for the unit solely for the share of Class A common stock underlying such unit.

We are not registering the shares of Class A common stock issuable upon exercise of the warrants at this time.  However, 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 registration statement covering the issuance, under the Securities Act, of the Class A common stock issuable upon exercise of the 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 registration statement, and a current prospectus relating thereto, until the expiration of the warrants in accordance with the provisions of the warrant agreement.  If any such registration statement has not been declared effective by the 60th business day following the closing of the initial business combination, holders of the warrants will have the right, during the period beginning on the 61st business day after the closing of the initial business combination and ending upon such registration statement being declared effective by the SEC, and during any other period when the company fails to have maintained an effective registration statement covering the issuance of the shares of Class A common stock issuable upon exercise of the warrants, to exercise such warrants on a “cashless basis.”

Notwithstanding the above, if our shares of Class A common stock are, at the time of any exercise of a warrant, 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 such event, each holder would pay the exercise price by surrendering the public 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 public warrants, multiplied by the excess of the “fair market value” (defined below) less the exercise price of the public 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 shares of Class A common stock for the ten 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 warrants when the price per share of Class A common stock equals or exceeds $18.00.

Once the warrants become exercisable, we may redeem the warrants (except as described herein with respect to the private placement warrants):

We will not redeem the warrants as described above unless a registration statement under the Securities Act covering the issuance of the shares of Class A common stock issuable upon exercise of the warrants is then effective and a current prospectus relating to those shares of Class A common stock is available throughout the 30-day redemption period.  If and when the 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 above, our management will have the option to require any holder that wishes to exercise his, her or its warrant to do so on a “cashless basis.”  In determining whether to require all holders to exercise their warrants on a “cashless basis,” our management will consider, among other factors, our cash position, the number of warrants that are outstanding and the dilutive effect on our stockholders of issuing the maximum number of shares of Class A common issuable upon the exercise of our warrants.  If our management takes advantage of this option, all holders of warrants 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 “fair market value” (defined below) over the exercise price of the warrants by (y) the fair market value.  The “fair market value” shall mean the average last reported sale price of the shares of Class A common stock for the 10-trading day period ending on the trading day prior to the date on which the notice of redemption is sent to the holders of warrants.  If our management takes advantage of this option, the notice of redemption will contain the information necessary to calculate the number of shares of Class A common stock to be received upon exercise of the warrants, including the “fair market value” in such case.  Requiring a cashless exercise in this manner will reduce the number of shares to be issued and thereby lessen the dilutive effect of a warrant redemption.  We believe this feature is an attractive option to us if we do not need the cash from the exercise of the warrants after our initial business combination.

We have established the last of the redemption criterion discussed above to prevent a redemption call unless there is at the time of the call a significant premium to the warrant exercise price.  If the foregoing conditions are satisfied and we issue a notice of redemption of the warrants, each warrant holder will be entitled to exercise his, her or its warrant prior to the scheduled redemption date.  However, the price of the Class A common stock 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 warrant as described under the heading “— Redeemable Warrants — Public Stockholders’ Warrants — Anti-dilution Adjustments”) as well as the $11.50 (for whole shares) warrant exercise price after the redemption notice is issued.

During the period beginning on the date the notice of redemption is given, holders may elect to exercise their warrants on a cashless basis.

Pursuant to the warrant agreement, references above to Class A common stock shall include a security other than Class A common stock into which the Class A common stock have been converted or exchanged for in the event we are not the surviving company in our initial business combination.

No fractional shares of Class A common stock will be issued upon exercise.  If, upon exercise, a holder would be entitled to receive a fractional interest in a share, we will round down to the nearest whole number of the number of shares of Class A common stock to be issued to the holder.  If, at the time of redemption, the warrants are exercisable for a security other than the shares of Class A common stock pursuant to the warrant agreement (for instance, if we are not the surviving company in our initial business combination), the warrants may be exercised for such security.  At such time as the warrants become exercisable for a security other than the shares of Class A common stock, the company (or surviving company) will use its commercially reasonable efforts to register under the Securities Act the security issuable upon the exercise of the warrants.

Redemption procedures

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

Anti-dilution adjustments

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

In addition, if we, at any time while the warrants are outstanding and unexpired, pay to all of the holders of Class A common stock a dividend or make a distribution in cash, securities or other assets to the holders of Class A common stock on account of such shares of Class A common stock (or other securities into which the 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 common stock during the 365-day period ending on the date of declaration of such dividend or distribution does not exceed $0.50 (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) 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 common stock in connection with a proposed initial business combination, (d) to satisfy the redemption rights of the holders of Class A common stock in connection with a stockholder vote to amend our 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 15 months from the closing of the IPO or during an extension period or (B) with respect to any other provision relating to stockholders’ 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 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 shares of Class A common stock in respect of such event.

If the number of issued and outstanding shares of Class A common stock is decreased by a consolidation, combination, reverse stock split or reclassification of shares of Class A common stock or other similar event, then, on the effective date of such consolidation, combination, reverse stock split, reclassification or similar event, the number of shares of Class A

common stock issuable on exercise of each warrant will be decreased in proportion to such decrease in issued and outstanding shares of Class A common stock.

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

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 an issue price or effective issue price of less than $9.20 per share of Class A common stock (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 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, the exercise price of the 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 prices described above under “— Redemption of warrants when the price per share of Class A common stock equals or exceeds $18.00” 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 shares of Class A common stock (other than those described above or that solely affects the par value of such shares of Class A common stock), or in the case of any 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 shares of Class A common stock), 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 warrants will thereafter have the right to purchase and receive, upon the basis and upon the terms and conditions specified in the warrants and in lieu of the shares of our Class A common stock 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 warrants would have received if such holder had exercised their 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 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 stockholders of the company as provided for in the company’s amended and restated certificate of incorporation or as a result of the redemption of shares of Class A common stock by the company if a proposed initial business combination is presented to the stockholders 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) securities representing more than 50% of the aggregate voting power represented by the issued and outstanding equity securities 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 stockholder 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 shares of Class A common stock 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 common stock in such a transaction is payable in the form of Class A common stock in the successor entity that is listed for trading on a national securities exchange or is quoted in an established over-the-counter market, or is to be so listed for trading or

quoted immediately following such event, and if the registered holder of the warrant properly exercises the warrant within 30 days following public disclosure of such transaction, the 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 warrant.

The warrants were 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 for the purpose of (i) curing 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 prospectus to the IPO, or defective provision, (ii) removing or reducing our ability to redeem the public 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 warrants in any material respect.  All other modifications or amendments, with respect to the terms of the public warrants or any provision of the warrant agreement with respect to the public warrants requires the vote or written consent by the holders of at least 50% of the then outstanding public warrants, and (b) with respect to the terms of the private placement warrants or any provision of the warrant agreement with respect to the private placement warrants requires the vote or written consent by the holders of at least 50% of the then outstanding private placement warrants.  You should review a copy of the warrant agreement for a complete description of the terms and conditions applicable to the warrants.

The warrant holders do not have the rights or privileges of holders of 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.

No fractional warrants will be issued upon separation of the units and only whole 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 common stock 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 stockholders, directors, officers and employees against all claims and losses 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.

Amended and Restated Certificate of Incorporation

Our amended and restated certificate of incorporation will contain certain requirements and restrictions that will apply to us until the completion of our initial business combination.  These provisions cannot be amended without the approval of the holders of greater than 50% of our common stock.  Our initial stockholders, who will collectively beneficially own 20% of our common stock, will participate in any vote to amend our amended and restated certificate of incorporation and will have the discretion to vote in any manner they choose.  Specifically, our amended and restated certificate of incorporation provides, among other things, that:

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 (iii) 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;

In addition, our amended and restated certificate of incorporation will 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 upon consummation of our initial business combination and after payment of underwriter’s fees and commissions.

Certain Anti-Takeover Provisions of Delaware Law and our Amended and Restated Certificate of Incorporation and Bylaws

We have opted out of Section 203 of the DGCL.  However, our amended and restated certificate of incorporation contains similar provisions providing that we may not engage in certain “business combinations” with any “interested stockholder” for a three-year period following the time that the stockholder became an interested stockholder, unless:

Generally, a “business combination” includes a merger, asset or stock sale or certain other transactions resulting in a financial benefit to the interested stockholder.  Subject to certain exceptions, an “interested stockholder” is a person who, together with that person’s affiliates and associates, owns, or within the previous three years owned, 15% or more of our voting stock.

Under certain circumstances, this provision will make it more difficult for a person who would be an “interested stockholder” to effect various business combinations with a corporation for a three-year period.  This provision may encourage companies interested in acquiring our company to negotiate in advance with our board of directors because the stockholder approval requirement would be avoided if our board of directors approves either the business combination or the transaction which results in the stockholder becoming an interested stockholder.  These provisions also may have the effect of preventing changes in our board of directors and may make it more difficult to accomplish transactions which stockholders may otherwise deem to be in their best interests.

Our amended and restated certificate of incorporation provides that the sponsor and its affiliates, any of its respective direct or indirect transferees who hold at least 15% of our outstanding common stock after such transfer and any group as to which such persons are party to, do not constitute “interested stockholders” for purposes of this provision.

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

Exclusive forum for certain lawsuits

Our amended and restated certificate of incorporation will require, to the fullest extent permitted by law, that derivative actions brought in our name, actions against directors, officers and employees for breach of fiduciary duty and other similar actions may be brought only in the Court of Chancery in the State of Delaware, except any action (A) as to which the Court of Chancery in the State of Delaware determines that there is an indispensable party not subject to the jurisdiction of the Court of Chancery (and the indispensable party does not consent to the personal jurisdiction of the Court of Chancery within ten days following such determination), (B) which is vested in the exclusive jurisdiction of a court or forum other than the Court of Chancery, (C) for which the Court of Chancery does not have subject matter jurisdiction, or (D) any action arising under the Securities Act, as to which the Court of Chancery and the federal district court for the District of Delaware shall have concurrent jurisdiction.  If an action is brought outside of Delaware, the stockholder bringing the suit will be deemed to have consented to service of process on such stockholder’s counsel.  Although we believe this provision benefits us by providing increased consistency in the application of Delaware law in the types of lawsuits to which it applies, a court may determine that this provision is unenforceable, and to the extent it is enforceable, the provision may have the effect of discouraging lawsuits against our directors and officers, although our stockholders will not be deemed to have waived our compliance with federal securities laws and the rules and regulations thereunder.

Our amended and restated certificate of incorporation will provide that the exclusive forum provision will be applicable to the fullest extent permitted by applicable law.  Section 27 of the Exchange Act creates exclusive federal jurisdiction over all suits brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder.  As a result, the exclusive forum provision will not apply to suits brought to enforce any duty or liability created by the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction.

Special meeting of stockholders

Our amended and restated certificate of incorporation provides that special meetings of our stockholders may be called only by a majority vote of our board of directors, by either our Chief Executive Officer or by our Chairman.

Advance notice requirements for stockholder proposals and director nominations

Our bylaws provide that stockholders seeking to bring business before our annual meeting of stockholders, or to nominate candidates for election as directors at our annual meeting of stockholders, must provide timely notice of their intent in writing.  To be timely, a stockholder’s notice will need to be received by the company secretary at our principal executive offices not later than the close of business on the 90th day nor earlier than the opening of business on the 120th day prior to the anniversary date of the immediately preceding annual meeting of stockholders.  Pursuant to Rule 14a-8 of the Exchange Act, proposals seeking inclusion in our annual proxy statement must comply with the notice periods contained therein.  Our bylaws also specify certain requirements as to the form and content of a stockholders’ meeting.  These provisions may preclude our stockholders from bringing matters before our annual meeting of stockholders or from making nominations for directors at our annual meeting of stockholders.

Action by written consent

Any action required or permitted to be taken by our common stockholders must be effected by a duly called annual or special meeting of such stockholders and may not be effected by written consent of the stockholders other than with respect to our Class B common stock.

Class B Common Stock Consent Right

For so long as any shares of Class B common stock remain outstanding, we may not, without the prior vote or written consent of the holders of a majority of the shares of Class B common stock then outstanding, voting separately as a single class, amend, alter or repeal any provision of our certificate of incorporation, whether by merger, consolidation or otherwise, if such amendment, alteration or repeal would alter or change the powers, preferences or relative, participating, optional or other or special rights of the Class B common stock.  Any action required or permitted to be taken at any meeting of the holders of Class B common stock may be taken without a meeting, without prior notice and without a vote, if a consent or consents in writing, setting forth the action so taken, shall be signed by the holders of the outstanding Class B common stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares of Class B common stock were present and voted.

Listing of Securities

Our units, Class A common stock and warrants are listed on Nasdaq under the symbols “ARCKU,” “ARCK” and “ARCKW,” respectively.
