 Exhibit 4.5 

ALTITUDE ACQUISITION CORP. 

DESCRIPTION OF SECURITIES 

The following summary of the material terms of the securities of Altitude Acquisition Corp., a Delaware corporation (“we,”
“us,” “our” or “the company”), is not intended to be a complete summary of the rights and preferences of such securities and is subject to and qualified by reference to our amended and restated certificate of
incorporation, as may be amended, our bylaws and the warrant agreement, dated December 8, 2020, between the company and Continental Stock Transfer & Trust Company (the “Warrant Agreement”), in each case incorporated by
reference as exhibits to the company’s Annual Report on Form 10-K for the year ended December 31, 2020 (the “Report”), and applicable Delaware law, including the Delaware General
Corporation Law, or DGCL. We urge you to read our amended and restated certificate of incorporation, as amended, our bylaws and the Warrant Agreement in their entirety for a complete description of the rights and preferences of our securities.

 General 
 We are a
Delaware corporation formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization, recapitalization or similar business combination with one or more businesses, which we refer to in this
document as our initial business combination, and our affairs are governed by our amended and restated certificate of incorporation, our bylaws and Delaware law, including the DGCL. Pursuant to our amended and restated certificate of incorporation,
our authorized capital stock consists of 300,000,000 shares of common stock, $0.0001 par value each, including up to 280,000,000 shares of Class A common stock, $0.0001 par value each, 20,000,000 shares of Class B common stock, par value
$0.0001 each, and 1,000,000 shares of preferred stock, $0.0001 par value each. The following description summarizes certain terms of our capital stock and warrants. 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-half of one redeemable warrant. Each whole warrant entitles the holder thereof to purchase one share of our Class A common stock at a price
of $11.50 per share, subject to certain adjustments. Pursuant to the warrant agreement, a warrant holder may exercise its warrants only for a whole number of the shares of the company’s Class A common stock. This means only a whole warrant
may be exercised at any given time by a warrant holder. For example, if a warrant holder holds one-half of one warrant to purchase a share of Class A common stock, such warrant will not be exercisable. If
a warrant holder holds two-halves of one warrant, such whole warrant will be exercisable for one share of Class A common stock at a 












 
price of $11.50 per share. No fractional warrants will be issued upon separation of the units and only whole warrants will trade. The common stock and warrants comprising the units began to trade
separately on January 29, 2021. Holders have the option to continue to hold units or separate their units into the component securities. 
 Common
Stock 
 As of March 29, 2021, there were 37,500,000 shares of common stock outstanding, consisting of 30,000,000 public shares and
7,500,000 founder shares held by the initial stockholders. 
 Stockholders of record are entitled to one vote for each share held on all
matters to be voted on by stockholders. Holders of Class A common stock and holders of 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 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. Our board of directors is divided into three classes, each of which will generally serve for a term of three years with only one class of directors being elected in each year. 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. 
 Because our amended and restated
certificate of incorporation authorizes the issuance of up to 380,000,000 shares of Class A common stock, if we were to enter into a business combination, we may (depending on the terms of such a business combination) be required to increase
the number of shares of Class A common stock which we are authorized to issue at the same time as our stockholders vote on the business combination to the extent we seek stockholder approval in connection with our initial business combination.
Our board of directors is divided into three classes with only one class of directors being elected in each year and each class (except for those directors appointed prior to our first annual meeting of stockholders) serving a three-year term. 

In accordance with Nasdaq corporate governance requirements, we are not required to hold an annual meeting until no later than one year after
our first fiscal year end following our listing on Nasdaq. Under Section 211(b) of the DGCL, we are, however, required to hold an annual meeting of stockholders for the purposes of electing directors in accordance with our bylaws, unless such
election is made by written consent in lieu of such a meeting. We may not hold an annual meeting of stockholders to elect new directors prior to the consummation of our initial business combination, and thus we may not be in compliance with
Section 211(b) of the DGCL, which requires an annual meeting. Therefore, if our stockholders want us to hold an annual meeting prior to the consummation of our initial business combination, they may attempt to force us to hold one by submitting
an application to the Delaware Court of Chancery in accordance with Section 211(c) of the DGCL. 
 We will provide our public
stockholders with the opportunity to redeem all or a portion of their 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 (which interest shall be net of taxes payable),
divided by the number of then outstanding public shares, subject to the limitations described herein. The amount in the trust account is $10.00 per public share. The per share amount we will distribute to investors who properly redeem their shares
will not be reduced by the deferred underwriting commissions we will pay to the representative of the underwriters. Our initial stockholders, 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 public shares held by them in connection with the completion of our initial business combination. Unlike many special purpose acquisition 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 requires 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 special purpose acquisition 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 the initial business combination only if a majority of the shares of common stock voted are voted in favor of the initial business combination. However, the participation of our sponsor, officers, directors,
advisors or their affiliates in privately-negotiated transactions (as described in this Report), if any, could result in the approval of our initial business combination even if a majority of our public stockholders vote, or indicate their intention
to vote, against such business combination. For purposes of seeking approval of the majority of our outstanding shares of common stock, non-votes will have no effect on the approval of our initial business
combination once a quorum is obtained. 
 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 provides that a public stockholder, together with any affiliate of such stockholder or any
other person with whom such stockholder is acting in concert or as a “group” (as defined under Section 13 of the Exchange Act), will be restricted from redeeming its shares with respect to Excess Shares, without our prior consent.
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 the initial business combination, and such stockholders could suffer a material loss in their investment if they sell such Excess Shares on the open market. Additionally, such stockholders will not receive
redemption distributions with respect to the Excess Shares if we complete the 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 shares in open market transactions, potentially at a loss. 
 If we seek stockholder approval in connection with our
initial business combination, our initial stockholders, sponsor, officers and directors have agreed to vote their founder shares and any public shares in favor of our initial business combination. Additionally, 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 by
June 11, 2022 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, 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 (which interest shall be net of taxes
payable and up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding public shares, which redemption will completely extinguish public stockholders’ rights as stockholders (including the right to
receive further liquidating distributions, if any), and (iii) as promptly as reasonably possible following such redemption, subject to the approval of our remaining stockholders and our board of directors, liquidate and dissolve, subject in
each case to our obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law. Our initial stockholders have entered into agreements 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 by June 11, 2022 or any extended period of time that we may have to consummate an initial business
combination as a result of an amendment to our amended and restated certificate of incorporation. 
 In the event of a liquidation,
dissolution or winding up of the company after a business combination, our stockholders are entitled to share ratably in all assets remaining available for distribution to them after payment of liabilities and after provision is made for each class
of shares, 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 public stockholders
with the opportunity to redeem their public shares for cash at a per share price equal to the aggregate amount then on deposit in the trust account, including interest earned on the funds held in the trust account (which interest shall be net of
taxes payable), divided by the number of then outstanding public shares, upon the completion of our initial business combination, subject to the limitations described herein. 












 Founder Shares 

The founder shares are designated as Class B common stock and, except as described below, are identical to the shares of Class A
common stock included in the units that were sold in our initial public offering, 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 initial stockholders, 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 public shares they hold in connection with the completion of our initial business combination, (B) to waive their redemption rights with respect to any founder shares and public shares they hold in connection
with a stockholder vote to approve an amendment to our amended and restated certificate of incorporation to modify the substance or timing of our obligation to redeem 100% of our public shares if we have not consummated an initial business
combination by June 11, 2022 or with respect to any other material provisions 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 they hold if we fail to complete our initial business combination by June 11, 2022 or any extended period of time that we may have to consummate an initial
business combination as a result of an amendment to our amended and restated certificate of incorporation, 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, and (iii) the founder shares are automatically convertible into Class A common stock concurrently with or immediately following the consummation of our initial business
combination on a one-for-one basis, subject to adjustment as described herein and in our amended and restated certificate of incorporation.. If we submit our initial
business combination to our public stockholders for a vote, our initial stockholders have agreed to vote their founder shares and any public shares in favor of our initial business combination. 

The founder shares will automatically convert into shares of Class A common stock concurrently with or immediately following the
consummation 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 connection with our initial business combination, the number
of shares of Class A common stock issuable upon conversion of all founder shares will equal, in the aggregate, on an as-converted basis, 20% of the total number of shares of Class A common stock
outstanding after such conversion (after giving effect to any redemptions of shares of Class A common stock by public stockholders), including the total number of shares of Class A common stock issued, or deemed issued or issuable upon
conversion or exercise of any equity-linked securities or rights issued or deemed issued, by the company in connection with or in relation to the consummation of the initial business combination, excluding any shares of Class A common stock or
equity-linked securities or rights exercisable for or convertible into shares of Class A common stock issued, or to be issued, to any seller in the initial business combination and any private placement warrants issued to our sponsor, officers
or directors upon conversion of working capital loans, provided that such conversion of founder shares will never occur on a less than one-for-one basis. 

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 earlier if, subsequent to our
initial business combination, the last sale price of the Class A common stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock capitalizations, 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, and (B) the date following the completion of our initial business combination on which we complete a
liquidation, merger, capital stock exchange or other similar transaction that results in all of our stockholders having the right to exchange their Class A common stock for cash, securities or other property. 

Preferred Stock 
 Our amended and restated
certificate of incorporation authorizes 1,000,000 shares of preferred stock and provides that shares of preferred stock may be issued from time to time in one or more series. Our board of directors is 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 may, without stockholder approval, issue shares
of preferred stock with voting and other rights that could adversely affect the voting power and other rights of the holders of the common stock and could have anti-takeover effects. The ability of our board of directors to issue shares of preferred
stock without stockholder approval could have the effect of delaying, deferring or preventing a change of control of us or the removal of existing management. We have no shares of preferred stock outstanding at the date hereof. Although we do not
currently intend to issue any shares of preferred stock, we cannot assure you that we will not do so in the future. 
 Warrants 

As of March, there were 23,000,000 warrants outstanding exercisable for 23,000,000 shares of common stock, consisting of 15,000,000 public
stockholders’ warrants and 8,000,000 private placement warrants. 
 Public Stockholders’ Warrants 

Each whole warrant entitles the registered holder to purchase one whole share of our 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 12 months from the closing of our initial public offering and 30 days after the completion of our initial business combination, provided in each case that we have an
effective registration statement under the Securities Act covering the shares of Class A common stock issuable upon exercise of the warrants and a current prospectus relating to them is available (or we permit holders to exercise their warrants
on a cashless basis under the circumstances specified in the warrant agreement) and such shares are registered, qualified or exempt from registration under the securities, or blue sky, laws of the state of residence of the holder. 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. Accordingly, unless at least two units are purchased, a warrant holder will not be able to receive or trade a whole warrant. 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 with respect to the Class A common stock
underlying the warrants is then effective and a prospectus relating thereto is current, subject to our satisfying our obligations described below with respect to registration. No warrant will be exercisable and we will not be obligated to issue a
share of Class A common stock upon exercise of a warrant unless the share of Class A common stock issuable upon such warrant exercise has been registered, qualified or deemed to be exempt under the securities laws of the state of residence
of the registered holder of the warrants. 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 no event will we be required to net cash settle any warrant. 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 have
agreed that as soon as practicable, but in no event later than fifteen (15) business days, after the closing of our initial business combination, we will use our best efforts to file with the SEC a registration statement for the registration,
under the Securities Act, of the Class A common stock issuable upon exercise of the warrants. We will use our best efforts to cause the same to become effective 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 a registration statement covering the shares of Class A common stock issuable upon exercise of the warrants is not
effective by the sixtieth (60th) business day after the closing of our initial business combination, warrant holders may, until such time as there is an effective registration statement and during any period when we will have failed to maintain an
effective registration statement, exercise warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act or another exemption. Notwithstanding the above, if our 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 we will be required to use our best efforts to register or qualify the shares under applicable blue sky laws to the extent an exemption is
not available. 
 Once the warrants become exercisable, we may call the warrants for redemption for cash: 

 

	 	•	 	 in whole and not in part; 



 

	 	•	 	 at a price of $0.01 per warrant; 



 

	 	•	 	 upon not less than 30 days’ prior written notice of redemption (the
“30-day redemption period”) to each warrant holder; and 


  

	 	•	 	 if, and only if, the reported last sale price of the common stock equals or exceeds $18.00 per share (as adjusted
for stock splits, stock capitalizations, reorganizations, recapitalizations and the like and for certain issuances of Class A common stock and equity-linked securities for capital raising purposes in connection with the closing of our initial
business combination as described elsewhere in this Report) for any 20 trading days within a 30-trading day period ending three business days before we send the notice of redemption to the warrant holders.



 If and when the warrants become redeemable by us for cash, 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. 
 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 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 well as the $11.50 (for whole
shares) warrant exercise price after the redemption notice is issued. 
 Redemption procedures cashless exercise 

If we call the warrants for redemption as described above, our management will have the option to require any holder that wishes to exercise
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 stock 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 their 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 Class A common stock underlying the
warrants, multiplied by the excess of the “fair market value” of our Class A common stock (defined below) over the exercise price of the warrants by (y) the fair market value. The “fair market value” shall mean the
average closing price of the Class A common stock for the 10 trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of 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. If we call our warrants for redemption and our management does not take advantage of this option, the holders of the private placement warrants and their permitted transferees would still be entitled
to exercise their private placement warrants for cash or on a cashless basis using the same formula described above that other warrant holders would have been required to use had all warrant holders been required to exercise their warrants on a
cashless basis, as described in more detail below. 
 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 4.9% or 9.8% (as specified by the holder) of the Class A common stock outstanding immediately after giving effect to such exercise. 












 If the number of outstanding shares of Class A common stock is increased by a share
capitalization payable in shares of Class A common stock, or by a split-up of common stock or other similar event, then, on the effective date of such share capitalization,
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 outstanding shares of common stock. A
rights offering to holders of common stock entitling holders to purchase shares of Class A common stock at a price less than the fair market value will be deemed a share capitalization of a number of shares of Class A common stock equal to
the product of (i) 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 Class A
common stock) and (ii) the quotient of (x) the price per share of Class A common stock paid in such rights offering and (y) the fair market value. For these purposes (i) 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 (ii) fair market value means the volume weighted average price of shares of Class A common stock as reported during the ten (10) trading day period ending on the trading day prior to the first date on which
the Class A common stock trades 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 a dividend or make a distribution in cash, securities or
other assets to the holders of Class A common stock on account of such Class A common stock (or other securities into which the warrants are convertible), other than (a) as described above, (b) certain ordinary cash dividends,
(c) to satisfy the redemption rights of the holders of Class A common stock in connection with a proposed initial business combination, or (d) 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 share of
Class A common stock in respect of such event. 
 If the number of outstanding shares of our Class A common stock is decreased by
a consolidation, combination, reverse share split or reclassification of Class A common stock or other similar event, then, on the effective date of such consolidation, combination, reverse share 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 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 initial stockholders or their affiliates, without taking into account any founder shares held by our initial stockholders 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
consummation of our initial business combination (net of redemptions), and the volume weighted average trading price of our Class A common stock during the 20 trading day period starting on the trading day after 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, and the $18.00 per share redemption trigger price 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 outstanding Class A common
stock (other than those described above or that solely affects the par value of such Class A common stock), or in the case of any merger or consolidation of us with or into another corporation (other than a consolidation or merger in which we
are the continuing corporation and that does not result in any reclassification or reorganization of our outstanding 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 of Class A common stock or other
securities or property (including cash) receivable upon such reclassification, reorganization, merger or consolidation, or upon a dissolution following any such sale or transfer, that the holder of the warrants would have received if such holder had
exercised their warrants immediately prior to such event. 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 thirty days following public disclosure of such transaction, the warrant exercise price will be reduced as specified in the warrant
agreement based on the Black-Scholes Warrant Value (as defined in the warrant agreement) of the warrant. The purpose of such exercise price reduction is to provide additional value to holders of the warrants when an extraordinary transaction occurs
during the exercise period of the warrants pursuant to which the holders of the warrants otherwise do not receive the full potential value of the warrants. 

The warrants have been 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 to cure any ambiguity or correct any defective provision, and that all other modifications or amendments will
require the vote or written consent of the holders of at least 50% of the then outstanding public warrants, and, solely with respect to any amendment to the terms of the private placement warrants, at least 50% of the then outstanding private
placement warrants. You should review a copy of the warrant agreement, which will be filed as an exhibit to this Report, for a complete description of the terms and conditions applicable to the warrants. 

The warrants may be exercised upon surrender of the warrant certificate on or prior to the expiration date at the offices of the warrant
agent, with the exercise form on the reverse side of the warrant certificate completed and executed as indicated, accompanied by full payment of the exercise price (or on a cashless basis, if applicable), by certified or official bank check payable
to us, for the number of warrants being exercised. The warrant holders do not have the rights or privileges of holders of common stock and any voting rights until they exercise their warrants and receive Class A common stock. After the issuance
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 shares will be issued upon exercise of the warrants. If, upon exercise of the warrants, a holder would be entitled to receive a
fractional interest in a share, we will, upon exercise, round down to the nearest whole number the number of shares of Class A common stock to be issued to the warrant holder. 

Private Placement Warrants 
 The private
placement warrants (including the Class A common stock issuable upon exercise of the private placement warrants) will not be transferable, assignable or salable until 30 days after the completion of our initial business combination (except,
among other limited exceptions, to our officers and directors and other persons or entities affiliated with the initial purchasers of the private placement warrants) and they will not be redeemable by us so long as they are held by the initial
stockholders or their permitted transferees. The initial purchasers, or their permitted transferees, have the option to exercise the private placement warrants on a cashless basis. Except as described in this section, the private placement warrants
have terms and provisions that are identical to those of the warrants sold as part of the units in our initial public offering. If the private placement warrants are held by holders other than the initial purchasers or their permitted transferees,
the private placement warrants will be redeemable by us and exercisable by the holders on the same basis as the warrants included in the units that were sold in our initial public offering. 












 If holders of the private placement warrants elect to exercise them on a cashless basis,
they would pay the exercise price by surrendering their 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 excess of the “fair market value” of our Class A common stock (as defined below) over the exercise price of the warrants by (y) the fair market value. The “fair market value” shall mean
the average closing price of the Class A common stock for the 10 trading days ending on the third trading day prior to the date on which the notice of warrant exercise is sent to the warrant agent. The reason that we have agreed that these
warrants will be exercisable on a cashless basis so long as they are held by the initial purchasers or their permitted transferees is because it is not known at this time whether they will be affiliated with us following a business combination. If
they remain affiliated with us, their ability to sell our securities in the open market will be significantly limited. We expect to have policies in place that prohibit insiders from selling our securities except during specific periods of time.
Even during such periods of time when insiders will be permitted to sell our securities, an insider cannot trade in our securities if he or she is in possession of material non-public information. Accordingly,
unlike public stockholders who could exercise their warrants and sell the shares of Class A common stock received upon such exercise freely in the open market in order to recoup the cost of such exercise, the insiders could be significantly
restricted from selling such securities. As a result, we believe that allowing the holders to exercise such warrants on a cashless basis is appropriate. 

In order to finance transaction costs in connection with an intended initial business combination, our sponsor or an affiliate of our sponsor
or certain of our officers and directors may, but are not obligated to, loan us funds as may be required. Up to $1,500,000 of such loans may be convertible into warrants of the post business combination entity at a price of $1.00 per warrant at the
option of the lender. Such warrants would be identical to the private placement warrants. Our initial stockholders have agreed not to transfer, assign or sell any of the private placement warrants (including the Class A common stock issuable
upon exercise of any of these warrants) until the date that is 30 days after the date we complete our initial business combination, except that among other limited exceptions, transfers can be made to our officers and directors and other persons or
entities affiliated with the sponsor. 
 Dividends 

We have not paid any cash dividends on our common stock to date and do not intend to pay cash dividends prior to the completion of a business
combination. The payment of cash dividends in the future will be dependent upon our revenues and earnings, if any, capital requirements and general financial conditions subsequent to completion of a business combination. The payment of any cash
dividends subsequent to a business combination will be within the discretion of our board of directors at such time. Further, if we incur any indebtedness, our ability to declare dividends may be limited by restrictive covenants we may agree to in
connection therewith. 
 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, One State
Street, New York, New York 10004. 
 Our Amended and Restated Certificate of Incorporation 

Our amended and restated certificate of incorporation contains 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 65% of our common stock. Specifically, our amended and restated certificate of incorporation, provides, among other things, that: 

 

	 	•	 	 If we are unable to complete our initial business combination by June 11, 2022, 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, 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 (which interest shall be net of taxes payable and up to $100,000 of interest to pay dissolution expenses), divided
by the number of then outstanding public shares, which redemption will completely extinguish public stockholders’ rights as stockholders (including the right to receive further
















	 	 
liquidating distributions, if any), and (iii) as promptly as reasonably possible following such redemption, subject to the approval of our remaining stockholders and our board of directors,
liquidate and dissolve, subject in each case to our obligations under Delaware law to provide for claims of creditors and in all cases subject to the requirements of other applicable law; 



 

	 	•	 	 Prior to our initial business combination, we may not issue additional securities that would entitle the holders
thereof to (i) receive funds from the trust account or (ii) vote as a class with our public shares on our initial business combination or (iii) to approve an amendment to our amended and restated certificate of incorporation to
(x) extend the time we have to consummate a business combination beyond June 11, 2022 or (y) amend the foregoing provisions; 


  

	 	•	 	 Although we do not intend to enter into a business combination with a target business that is affiliated with our
sponsor, our directors or our executive officers, we are not prohibited from doing so. In the event we enter into such a transaction, we, or a committee of independent directors, will obtain an opinion from an independent investment banking firm
which is a member of FINRA or a valuation or appraisal firm that such a business combination is fair to our company from a financial point of view; 


  

	 	•	 	 If a stockholder vote on our initial business combination is not required by law and we do not decide to hold a
stockholder vote for business or other legal reasons, we will offer to redeem our public shares pursuant to Rule 13e-4 and Regulation 14E of the Exchange Act, and will file tender offer documents with the SEC
prior to completing our initial business combination which contain substantially the same financial and other information about our initial business combination and the redemption rights as is required under Regulation 14A of the Exchange Act.
Whether or not we maintain our registration under the Exchange Act or our listing on Nasdaq, we will provide our public stockholders with the opportunity to redeem their public shares by one of the two methods listed above; 



 

	 	•	 	 We must complete one or more business combinations having an aggregate fair market value of at least 80% of the
assets held in the trust account (excluding the deferred underwriting commissions, and taxes payable on the income earned on the trust account) at the time of the agreement to enter into the initial business combination; 



 

	 	•	 	 If our stockholders approve an amendment to our amended and restated certificate of incorporation to modify the
substance or timing of our obligation to redeem 100% of our public shares if we do not complete our initial business combination by June 11, 2022 or, with respect to any other material provisions relating to stockholders’ rights or pre-initial business combination activity, we will provide our public stockholders with the opportunity to redeem all or a portion of their Class A common stock upon such approval 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 (which interest shall be net of taxes payable),
divided by the number of then outstanding public shares, subject to the limitations described herein; and 


  

	 	•	 	 We will not effectuate our initial business combination with another blank check company or a similar company
with nominal operations. 


 In addition, our amended and restated certificate of incorporation provides 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. 
 Certain Anti-Takeover
Provisions of Delaware Law and our Amended and Restated Certificate of Incorporation and Bylaws 
 We are subject to the provisions of
Section 203 of the DGCL regulating corporate takeovers. This statute prevents certain Delaware corporations, under certain circumstances, from engaging in a “business combination” with: 

 

	 	•	 	 a stockholder who owns 15% or more of our outstanding voting stock (otherwise known as an “interested
stockholder”); 


  

	 	•	 	 an affiliate of an interested stockholder; or 



 

	 	•	 	 an associate of an interested stockholder, for three years following the date that the stockholder became an
interested stockholder. 














 A “business combination” includes a merger or sale of more than 10% of our assets.
However, the above provisions of Section 203 do not apply if: 
  

	 	•	 	 our board of directors approves the transaction that made the stockholder an “interested stockholder,”
prior to the date of the transaction; 


  

	 	•	 	 after the completion of the transaction that resulted in the stockholder becoming an interested stockholder, that
stockholder owned at least 85% of our voting stock outstanding at the time the transaction commenced, other than statutorily excluded shares of common stock; or 



 

	 	•	 	 on or subsequent to the date of the transaction, the initial business combination is approved by our board of
directors and authorized at a meeting of our stockholders, and not by written consent, by an affirmative vote of at least two-thirds of the outstanding voting stock not owned by the interested stockholder.



 Our amended and restated certificate of incorporation provides that our board of directors is classified into three
classes of directors. As a result, in most circumstances, a person can gain control of our board only by successfully engaging in a proxy contest at two or more annual meetings. 

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. 
 Special meeting of
stockholders 
 Our bylaws provide that special meetings of our stockholders may be called only by a majority vote of our board of
directors, by 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. 

Listing of Securities 
 Our units,
Class A common stock and warrants are listed on the Nasdaq Capital Market under the symbols “ALTUU,” “ALTU” and “ALTUW,” respectively.
