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, Semper Paratus Acquisition 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, 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 221,000,000 shares of capital stock, including 200,000,000 Class A ordinary shares, $0.0001 par value and 20,000,000 Class B ordinary shares, $0.0001 par value, and 1,000,000 shares of undesignated preferred stock, $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 consists of one Class A ordinary share and one-half of one redeemable warrant. Each whole warrant entitles the holder thereof to purchase one Class A ordinary share exercisable at $11.50 per full share.

Ordinary Shares

Ordinary shareholders of record are entitled to one vote for each share held on all matters to be voted on by shareholders. Except as described below, holders of Class A ordinary shares and holders of Class B ordinary shares will vote together as a single class on all matters submitted to a vote of our shareholders except as required by law. Approval of certain actions will require a special resolution under Cayman Islands law, being the affirmative vote of at least two-thirds of our ordinary shares that are voted, 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. There is no cumulative voting with respect to the appointment of directors, with the result that the holders of more than 50% of the shares voted for the appointment of directors can appoint 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.

We will provide our public shareholders with the opportunity to redeem all or a portion of their public shares upon the completion of our initial business combination at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account calculated as of two business days prior to the consummation of our initial business combination, including interest earned on the funds held in the trust account and not previously released to us to pay our taxes, if any, divided by the number of the 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 underwriters. The redemption rights will include the requirement that a beneficial owner must identify itself in order to valid redeem its shares. Our initial shareholders and each member of our management team have entered into an 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 (i) the completion of our initial business combination and (ii) a shareholder vote to approve an amendment to our amended and restated memorandum and articles of association (A) that would modify the substance or timing of our obligation to provide holders of our Class A ordinary shares the right to have their shares redeemed in connection with our initial business combination or to redeem 100% of our public shares if we do not complete our

initial business combination by February 8, 2023 (or by the end of any Extension Period) or (B) with respect to any other provision relating to the rights of holders of our Class A ordinary shares.

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 Excess Shares, without our prior consent. However, we would not be restricting our shareholders’ ability to vote all of their shares (including Excess Shares) for or against our initial business combination. Our shareholders’ inability to redeem the Excess Shares will reduce their influence over our ability 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 our initial 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 public shareholders 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 and not previously released to us to pay our taxes, if any, divided by the number of the then-outstanding public shares, upon the completion of our initial business combination, subject to the limitations described herein.

Redeemable Warrants

Each warrant entitles the holder thereof to purchase one Class A ordinary share at a price of $11.50 per full share, subject to adjustment as described below, at any time commencing on the later of (i) 30 days after the completion of the Company’s initial business combination and (ii) November 8, 2022. Pursuant to the warrant agreement, a warrant holder may exercise its warrants only for a whole number of shares.

The warrants will become exercisable 30 days after the completion of our initial business combination; provided that we have an effective registration statement under the Securities Act covering the issuance of the Class A ordinary shares issuable upon exercise of the warrants and a current prospectus relating to them is available 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 (or we permit holders to exercise their warrants on a cashless basis under the circumstances specified in the warrant agreement).

No warrants will be exercisable for cash unless we have an effective and current registration statement covering the Class A ordinary shares issuable upon exercise of the warrants and a current prospectus relating to such Class A ordinary shares.

Notwithstanding the above, 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, and in the event we do not so elect, 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.

The warrants will expire at 5:00 p.m., New York City time, five years after the completion of our initial business combination or earlier upon redemption or liquidation. On the exercise of any warrant, the warrant exercise price will be paid directly to us and not placed in the trust account.

We may call the warrants for redemption (excluding the private warrants, and any outstanding representative’s warrants, and any warrants underlying units issued to our sponsor, initial shareholders, officers, directors or their affiliates in payment of working capital loans made to us), in whole and not in part, at a price of $0.01 per warrant:

· at any time while the warrants are exercisable;

· upon not less than 30 days’ prior written notice of redemption to each warrant holder; and

· if, and only if, the reported last sale price of the ordinary shares equals or exceeds $18.00 per share (as adjusted for share sub-divisions, share dividends, reorganizations and recapitalizations), for any 20 trading days within a 30 trading day period ending on the third trading day prior to the date on which notice of the redemption is given to the warrant holders.

We will not redeem the warrants as described above unless an effective registration statement under the Securities Act covering the Class A ordinary shares issuable upon exercise of the warrants is 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.

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

If and when the warrants become redeemable by us, we may not exercise our redemption right if the issuance of ordinary shares upon exercise of the warrants is not exempt from registration or qualification under applicable state blue sky laws or we are unable to effect such registration or qualification. We will use our best efforts to register or qualify such ordinary shares under the blue sky laws of the state of residence in those states in which the warrants were offered by us in our initial public offering.

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 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” shall mean the average reported last sale price of the ordinary shares 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. Whether we will exercise our option to require all holders to exercise their warrants on a “cashless basis” will depend on a variety of factors including the price of our ordinary shares at the time the warrants are called for redemption, our cash needs at such time and concerns regarding dilutive share issuances.

The warrants are issued in registered form under a warrant agreement between Continental, 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, but requires the approval, by written consent or vote, of the holders of a majority of the then outstanding warrants in order to make any change that adversely affects the interests of the registered holders.

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 ordinary shares and any voting rights until they exercise their warrants and receive ordinary shares. After the issuance of 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.

Except as described above, no public warrants will be exercisable and we will not be obligated to issue ordinary shares unless at the time a holder seeks to exercise such warrant, a prospectus relating to the ordinary shares issuable upon exercise of the warrants is current and the ordinary shares have been registered or qualified or deemed to be exempt under the securities laws of the state of residence of the holder of the warrants. Under the terms of the warrant agreement, we have agreed to use our best efforts to meet these conditions and to maintain a current prospectus relating to the ordinary shares issuable upon exercise of the warrants until the expiration of the warrants. However, we cannot assure you that we will be able to do so and, if we do not maintain a current prospectus relating to the ordinary shares issuable upon exercise of the warrants, holders will be unable to exercise their warrants and we will not be required to settle any such warrant exercise. If the prospectus relating to the ordinary shares issuable upon the exercise of the warrants is not current or if the ordinary shares is not qualified or exempt from qualification in the jurisdictions in which the holders of the warrants reside, we will not be required to net cash settle or cash settle the warrant exercise, the warrants may have no value, the market for the warrants may be limited and the warrants may expire worthless.

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

No fractional shares will be issued upon exercise of the warrants once the Units separate, and no cash will be payable in lieu thereof. As a result, you must exercise warrants in multiples of two warrants, at an exercise price of $11.50 per full share, subject to adjustment as described in this Report to validly exercise your 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 ordinary shares to be issued to the warrant holder.
