 Exhibit 4.5 

DESCRIPTION OF THE REGISTRANT’S SECURITIES REGISTERED PURSUANT TO SECTION 12 OF THE SECURITIES EXCHANGE ACT OF 1934, AS AMENDED

 As of December 31, 2021, Enterprise 4.0 Technology Acquisition Corp. (“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, consisting of one Class A ordinary share (as
defined below) and one-half of one redeemable warrant (as defined below), with each whole warrant entitling the holder thereof to purchase one Class A ordinary share (the “units”), (ii) its
Class A ordinary shares, $0.0001 par value per share (“Class A ordinary shares”), and (iii) its public warrants, with each whole warrant exercisable for one Class A ordinary share for $11.50 per share (the
“warrants”). 
 Pursuant to our amended and restated memorandum and articles of association, our authorized capital stock consists
of 555,000,000 shares, including 500,000,000 Class A ordinary shares, $0.0001 par value and 50,000,000 Class B ordinary shares, $0.0001 par value, and 5,000,000 undesignated preferred shares, $0.0001 par value. The following description
summarizes the material terms of our capital stock and does not purport to be complete. It is subject to, and qualified in its entirety by reference to, our amended and restated memorandum and articles of association, and our warrant agreement, each
of which is incorporated by reference as an exhibit to our Annual Report on Form 10-K for the year ended December 31, 2021 (the “Report”) of which this Exhibit 4.5 is a part. 

Defined terms used herein but not otherwise defined shall have the meaning ascribed to such terms in the Report. 

Units 
 Each unit has an offering price of
$10.00 and consists of one Class A ordinary share and one-half of one warrant. Each whole warrant entitles the holder thereof to purchase one Class A ordinary share at a price of $11.50 per
share, subject to adjustment as described in this Report. Warrants must be exercised for one whole Class A ordinary share. 
 Ordinary Shares

 Except as described below, Class A ordinary shareholders and Class B ordinary shareholders of record are entitled to one
vote for each share held on all matters to be voted on by shareholders and vote together as a single class, except as required by law. Unless specified in the Companies Act, our amended and restated memorandum and articles of association or
applicable stock exchange rules, an ordinary resolution is required to approve any such matter voted on by our shareholders. Approval of certain actions will require a special resolution under Cayman Islands law and pursuant to our amended and
restated memorandum and articles of association; such actions include amending our amended and restated memorandum and articles of association and approving a statutory merger or consolidation with another company. Our board of directors will be
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 founder shares voted for the election of directors can elect all of the directors. Our shareholders 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 the holders of our founder shares will be entitled to vote on the appointment of our directors. Holders of our public shares will not be entitled to vote on the appointment of
directors during such time. In addition, prior to the completion of an initial business combination, holders of our founder shares may by ordinary resolution remove a member of the board of directors for any reason. In addition, in a vote to
transfer our company by way of continuation out of the Cayman Islands to another jurisdiction (including, but not limited to, the approval of the organizational documents of the company in such other jurisdiction) (which requires a special
resolution) prior to our initial business combination, holders of our founder shares will have ten votes for every founder share and holders of our Class A ordinary shares will have one vote for every Class A ordinary share. These
provisions of our amended and restated memorandum and articles of association may only be amended (i) prior to the completion of an initial business combination, by a special resolution passed by at least 90% of the votes cast by the holders of
issued shares present in person or by proxy at a general meeting and entitled to vote, or (ii) in connection with and immediately prior to the completion of an initial business combination or following the completion of an initial business
combination, by a special resolution passed by at least a two-thirds majority of the votes cast by the holders of the issued shares present in person or by proxy at a general meeting and entitled to vote.

 We will provide our Class A public shareholders with the opportunity to redeem all or a portion of their public shares upon the
completion of our initial business combination at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account as of two business days prior to the completion of
our initial business combination, including interest (which interest shall be net of taxes payable) divided by the number of then outstanding public shares, 











 
subject to the limitations described herein. The redemption rights will include the requirement that a beneficial holder must identify itself in order to validly redeem its shares. Our initial
holders, sponsor, officers, directors and advisors have entered into a letter agreement with us, pursuant to which they have agreed to waive their redemption rights with respect to their founder shares, placement shares and public shares in
connection with the completion of our initial business combination. 
 If we seek shareholder approval of our initial business combination
and we do not conduct redemptions in connection with our initial business combination pursuant to the tender offer rules, our amended and restated memorandum and articles of association provide that a public shareholder, together with any affiliate
of such shareholder or any other person with whom such shareholder is acting in concert or as a “group” (as defined under Section 13 of the Exchange Act), will be restricted from redeeming its shares with respect to more than an
aggregate of 15% of the ordinary shares sold in our initial public offering, which we refer to as the “Excess Shares.” However, we would not be restricting our shareholders’ ability to vote all of their shares (including Excess
Shares) for or against our initial business combination. Our shareholders’ inability to redeem the Excess Shares will reduce their influence over our ability to complete our initial business combination, and such shareholders could suffer a
material loss in their investment if they sell such Excess Shares on the open market. Additionally, such shareholders will not receive redemption distributions with respect to the Excess Shares if we complete the business combination. And, as a
result, such shareholders will continue to hold that number of shares exceeding 15% and, in order to dispose such shares would be required to sell their shares in open market transactions, potentially at a loss. 

In the event of a liquidation, dissolution or winding up of the company after a business combination, our shareholders 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 ordinary shares. Our shareholders have no preemptive or other
subscription rights. There are no sinking fund provisions applicable to the ordinary shares, except that we will provide our shareholders with the opportunity to redeem their public shares for cash equal to their pro rata share of the aggregate
amount then on deposit in the trust account, including interest (which interest shall be net of taxes payable) upon the completion of our initial business combination, subject to the limitations described the Report. 

Redeemable Warrants 
 Each whole warrant
entitles the registered holder to purchase one Class A ordinary share at a price of $11.50 per share, subject to adjustment as discussed below, at any time commencing 30 days after the completion of our initial business combination.
Pursuant to the warrant agreement, a warrant holder may exercise its warrants only for a whole number of Class A ordinary shares. 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. 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 ordinary shares 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 ordinary shares 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, or a valid exemption from registration is available. No warrant will be exercisable and we will not be obligated to issue a Class A ordinary share upon exercise of
a warrant unless the Class A ordinary shares 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 Class A ordinary share underlying such unit. 
 We have agreed that as soon as practicable, but in no event later than 20 days
after the closing of our initial business combination, we will use our reasonable best efforts to file with the SEC a registration statement for the registration, under the Securities Act, of the Class A ordinary shares issuable upon exercise
of the warrants, and we will use our reasonable best efforts to cause the same to become effective within 60 days after the closing of our initial business combination, and to maintain the effectiveness of such registration statement and a current
prospectus relating to those Class A ordinary shares until the warrants expire or are redeemed, as specified in the warrant agreement provided that if our Class A ordinary shares 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 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 use our best efforts to












 
register or qualify the shares under applicable blue sky laws to the extent an exemption is not available. If a registration statement covering the Class A ordinary shares issuable upon
exercise of the warrants is not effective by the 60th day after the closing of the 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, but we
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 warrants for that
number of Class A ordinary shares equal to the quotient obtained by dividing (x) the product of the number of Class A ordinary shares underlying the warrants, multiplied by the difference between the exercise price of the warrants and
the “fair market value” (defined below) by (y) the fair market value. The “fair market value” as used in this paragraph shall mean the average reported last sale price of the Class A ordinary shares as reported during
the ten (10) day period ending on the trading day prior to the date that the notice of redemption is sent to the warrant holders. 

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

 

	 	•	 	 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 to each warrant holder; and



  

	 	•	 	 if, and only if, the closing price of the Class A ordinary shares equals or exceeds $18.00 per share (as
adjusted for share sub-divisions, share capitalizations, reorganizations, recapitalizations and the like) for any 20 trading days within a 30-trading day period
commencing once the warrants become exercisable and ending three business days before we send the notice of redemption to the warrant holders. 



We will not redeem the warrants as described above unless a registration statement under the Securities Act covering the issuance of the
Class A ordinary shares issuable upon exercise of the warrants is then effective and a current prospectus relating to those Class A ordinary shares 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 all holders that wish to exercise
warrants to do so on a “cashless basis.” In such event, each holder would pay the exercise price by surrendering the warrants for that number of Class A ordinary shares equal to the quotient obtained by dividing (x) the product
of the number of Class A ordinary shares underlying the warrants, multiplied by the difference between the exercise price of the warrants and the “fair market value” by (y) the fair market value. 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 ordinary shares may fall below the $18.00 redemption trigger price (as adjusted for
share sub-divisions, share capitalizations, reorganizations, recapitalizations and the like) as well as the $11.50 (for whole shares) warrant exercise price after the redemption notice is issued. 

No fractional Class A ordinary shares 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 Class A ordinary shares to be issued to the holder. If, at the time of redemption, the warrants are exercisable for a security other than the Class A
ordinary shares 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 Class A ordinary shares, the Company (or surviving company) will use its commercially reasonable best efforts to register under the Securities Act the security issuable upon the exercise of the warrants. 

Ownership Limitation. 
 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 Class A ordinary shares issued and outstanding immediately after giving
effect to such exercise. 











 Anti-dilution Adjustments.    The
warrants have certain anti-dilution and adjustments rights upon certain events. In addition, if (x) we issue additional Class A ordinary shares or equity-linked securities for capital raising purposes in connection with the closing of
our initial business combination at an issue price or effective issue price of less than $9.20 per ordinary share (with such issue price or effective issue price to be determined in good faith by our board of directors and, in the case
of any such issuance to our sponsor or its affiliates, without taking into account any founder shares or placement units held by our sponsor or such affiliates, as applicable, prior to such issuance) (the “Newly Issued Price”),
(y) the aggregate gross proceeds from such issuances represent more than 60% of the total equity proceeds, and interest thereon, available for the funding of our initial business combination on the date of the completion of our initial business
combination (net of redemptions), and (z) the volume weighted average trading price of our Class A ordinary shares during the 20 trading day period starting on the trading day prior to the day on which we complete 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 described above will be adjusted (to the nearest cent) to be equal to 180% of the higher of the Market Value and the Newly Issued Price. 

The warrants will be issued in registered form under a warrant agreement between Continental Stock Transfer & Trust Company, as
warrant agent, and us. The warrant agreement provides that the terms of the warrants may be amended without the consent of any holder 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 this Report, or defective provision (ii) amending the provisions relating to cash dividends on ordinary shares as contemplated by and in
accordance with the warrant agreement 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, provided that the approval by the holders of a majority of the then-outstanding warrants is required to make any change that adversely affects the
interests of the registered holders. You should review a copy of the warrant agreement, which was filed with the Registration Statement, 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 ordinary shares and any voting rights until they exercise their
warrants and receive Class A ordinary shares. After the issuance of Class A ordinary shares 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
shareholders. 
 Warrants may be exercised only for a whole number of Class A ordinary shares. 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 Class A ordinary shares to be
issued to the warrant holder.
