Description of Registered Securities

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, Tristar Acquisition I Corp. (“we,” “our,” “us” or the “Company”) had the following four classes of securities registered under Section 12 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”): (i) its units, each consisting of one Class A ordinary share (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 (ii) its Class A ordinary shares, $0.0001 par value per share (the “Class A ordinary shares”), (iii) its Class B ordinary shares, $0.0001 par value per share (the “Class B ordinary shares”), and (iv) 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 articles of association, our authorized capital stock consists of 90,000,000 Class A ordinary shares, $0.0001 par value per share, 10,000,000 Class B ordinary shares, par value $0,0001 per share, and 1,000,000 preference shares, $0.0001 par value per share. 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 articles of association and our warrant agreement, both of which are 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 redeemable warrant entitles the holder thereof to purchase one ordinary share at a price of $11.50 per share. Pursuant to the warrant agreement, a warrant holder may exercise its warrants only for a whole number of ordinary shares.

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. Unless specified in our amended and restated memorandum and articles of association, or as required by applicable provisions of the Companies Act or applicable stock exchange rules, the affirmative vote of a majority of our ordinary shares that are voted is required to approve any such matter voted on by our shareholders. 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. 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 appointed in each year. 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. Prior to our initial business combination, holders of our founder shares are the only shareholders of the Company that will have the right to vote on the appointment 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. The provisions of our amended and restated memorandum and articles of association governing the appointment or removal of directors prior to our initial business combination may only be amended by a special resolution passed by not less than two-thirds of our ordinary shares who attend and vote at our general meeting which shall include the affirmative vote of a simple majority of our Class B ordinary shares.

If we seek shareholder approval, we will complete our initial business combination only if we obtain the approval of an ordinary resolution under Cayman Islands law, being the affirmative vote of a majority of the ordinary shares represented in person or by proxy and entitled to vote thereon and who vote at a general meeting. In such case, our Sponsor and each member of our management team have agreed to vote their founder shares and public shares, and the anchor investors have agreed to vote all founder shares held by hem, in favor of our initial business combination. As a result, in addition to our founder shares, we would need 7,500,001, or 37.5% (assuming the over-allotment option is not exercised and that the size of this offering is not increased), of the 20,000,000 public shares sold in this offering to be voted in favor of an initial business combination in order to have our initial business combination approved. Accordingly, if we seek shareholder approval of our initial business combination, the agreement by our Sponsor and

each member of our management team to vote, and the agreements by the anchor investors to vote any founder shares held by them, in favor of our initial business combination will increase the likelihood that we will receive the requisite shareholder approval for such initial business combination. In the event that the anchor investors purchase the units that they have expressed an interest in purchasing in this offering, hold them until prior to our initial business combination and vote their public shares in favor of our initial business combination, we would not need any of the other public shares sold in this offering to be voted in favor of an initial business combination for our shareholders to approve our initial business combination. The anchor investors have agreed to vote founder shares they purchase from our Sponsor in favor of our initial business combination, but are not required to vote any of their public shares in favor of our initial business combination or for or against any other matter presented for a shareholder vote. Additionally, each public shareholder may elect to redeem their public shares irrespective of whether they vote for or against the proposed transaction or vote at all.

Founder Shares

The founder shares are designated as Class B ordinary shares and, except as described below, are identical to the Class A ordinary shares included in the units being sold in this offering, and holders of founder shares have the same shareholder rights as public shareholders, except that: (a) prior to our initial business combination, only holders of the founder shares have the right to vote on the appointment of directors and holders of a majority of our founder shares may remove a member of the Board of Directors for any reason; (b) the founder shares are subject to certain transfer restrictions, as described in more detail below; (c) our Sponsor and each member of our management team have entered into an agreement with us, pursuant to which they have agreed to (i) waive their redemption rights with respect to their founder shares (ii) to waive their redemption rights with respect to their founder shares and public shares in connection with 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 within 18 months (or 21 months, as applicable) from the closing of this offering or (B) with respect to any other provision relating to the rights of holders of our Class A ordinary shares; and (iii) waive their rights to liquidating distributions from the trust account with respect to any founder shares they hold if we fail to consummate an initial business combination within 18 months (or 21 months, as applicable) from the closing of this offering (although they will be entitled to liquidating distributions from the trust account with respect to any public shares they hold if we fail to complete our initial business combination within the prescribed time frame); (d) the founder shares will automatically convert into our Class A ordinary shares at the time of our initial business combination or earlier at the option of the holders thereof as described herein; and (e) the founder shares are entitled to registration rights. If we seek shareholder approval, we will complete our initial business combination only if we obtain the approval of an ordinary resolution under Cayman Islands law, being the affirmative vote of a majority of the ordinary shares, represented in person or by proxy and entitled to vote thereon, and who vote at a general meeting. In such case, our Sponsor and each member of our management team have agreed to vote their founder shares and public shares, and the anchor investors have agreed to vote any founder shares held by them, in favor of our initial business combination.

Except as described herein, our Sponsor, our directors and executive officers and the anchor investors have agreed not to transfer, assign or sell any of their founder shares until earliest of (A) one year after the completion of our initial business combination and (B) subsequent to our initial business combination, (x) if the closing price of our Class A ordinary shares equals or exceeds $12.00 per share (as adjusted for share sub-divisions, share 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, or (y) the date on which we complete a liquidation, merger, share exchange or other similar transaction that results in all of our public shareholders having the right to exchange their ordinary shares for cash, securities or other property. We refer to such transfer restrictions throughout this prospectus as the lock-up. Any permitted transferees would be subject to the same restrictions and other agreements of our Sponsor and our directors and executive officers with respect to any founder shares.

Prior to our initial business combination, only holders of our founder shares will have the right to vote on the appointment of 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 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 memorandum and articles of association may only be amended by a special resolution passed by not

less than two-thirds of our ordinary shares who attend and vote at our general meeting which shall include the affirmative vote of a simple majority of our Class B ordinary shares. With respect to any other matter submitted to a vote of our shareholders, 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.

Redeemable Warrants

Each redeemable 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 following of the completion of an 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.

Except as set forth below, 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 foregoing, if a registration statement covering the ordinary shares issuable upon exercise of the warrants is not effective within 60 days from the consummation of our initial business combination, warrant holders may, until such time as there is an effective registration statement and during any period when we shall have failed to maintain an effective registration statement, exercise warrants on a cashless basis pursuant to the exemption from registration provided by Section 3(a)(9) of the Securities Act provided that such exemption is available. If an exemption from registration is not available, holders will not be able to exercise their warrants on a cashless basis.

The warrants will expire five years from the consummation of our initial business combination at 5:00 p.m., New York City time.

Redemption of warrants when the price per Class A ordinary share equals or exceeds $18.00.    Once the warrants become exercisable, we may redeem the outstanding warrants (except as described herein with respect to the private placement warrants):

Redemption of warrants when the price per Class A ordinary share equals or exceeds $10.00.    Once the warrants become exercisable, we may redeem the outstanding warrants:

Beginning on the date the notice of redemption is given until the warrants are redeemed or exercised, holders may elect to exercise their warrants on a cashless basis. The numbers in the table below represent the number of Class A ordinary shares that a warrant holder will receive upon such cashless exercise in connection with a redemption by us pursuant to this redemption feature, based on the “fair market value” of our Class A ordinary shares on the corresponding redemption date (assuming holders elect to exercise their warrants and such warrants are not redeemed for $0.10 per warrant), determined for these purposes based on volume weighted average price of our Class A ordinary shares during the 10 trading days immediately following the date on which the notice of redemption is sent to the holders of warrants, and the number of months that the corresponding redemption date precedes the expiration date of the warrants, each as set forth in the table below. We will provide our warrant holders with the final fair market value no later than one business day after the 10-trading day period described above ends. The warrants have certain anti-dilution and adjustments rights upon certain events.

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 prospectus, 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 at least 65% of the then-outstanding public warrants is required to make any change that adversely affects the interests of the registered holders. The exercise price and number of Class A ordinary shares issuable on exercise of the warrants may be adjusted in certain circumstances including in the event of a capitalization of shares, extraordinary dividend or our recapitalization, reorganization, merger or consolidation. However, the warrants will not be adjusted for issuances of Class A ordinary shares at a price below their respective exercise prices.

In addition, if 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 share, the aggregate gross proceeds from such issuances represent more than 65% 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 Market Value is below $9.20 per share, then the exercise price of each warrant will be adjusted such that the effective exercise price per full share will be equal to 115% of the higher of the Market Value and the price at which we issue the additional Class A ordinary shares or equity-linked securities. This may make it more difficult for us to consummate an initial business combination with a target business.

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, 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 Class A 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.

Except as described below, the private placement warrants have terms and provisions that are identical to those of the warrants being sold as part of the units in this offering. The private placement warrants (including the Class A ordinary shares 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 pursuant to limited exceptions as described under “Principal Shareholders — Transfers of Founder Shares and Private Placement Warrants,” 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 (except as described under “— Warrants

— Public Shareholders’ Warrants — Redemption of warrants when the price per Class A ordinary share equals or exceeds $10.00”) so long as they are held by our Sponsor or its permitted transferees (except as otherwise set forth herein). Our Sponsor, or its permitted transferees, has the option to exercise the private placement warrants on a cashless basis. If the private placement warrants are held by holders other than our Sponsor or its permitted transferees, the private placement warrants will be redeemable by us in all redemption scenarios and exercisable by the holders on the same basis as the warrants included in the units being sold in this offering. Any amendment to the terms of the private placement warrants or any provision of the warrant agreement with respect to the private placement warrants will require a vote of holders of at least 65% of the number of the then outstanding private placement warrants.

Except as described above, if holders of the private placement warrants elect to exercise them on a cashless basis, they would pay the exercise price by surrendering his, her or its warrants for that number of Class A ordinary shares equal to the quotient obtained by dividing (x) the product of the number of Class A ordinary shares underlying the warrants, multiplied by the excess of the “Sponsor fair market value” (defined below) over the exercise price of the warrants by (y) the Sponsor fair market value. For these purposes, the “Sponsor fair market value” shall mean the average reported closing price of the Class A ordinary shares 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 our Sponsor and its 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 restrict 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 shareholders who could exercise their warrants and sell the Class A ordinary shares 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.

Except as described above, no warrants will be exercisable and we will not be obligated to issue Class A ordinary shares unless at the time a holder seeks to exercise such warrant, a prospectus relating to the Class A ordinary shares issuable upon exercise of the warrants is current and the Class A 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 Class A 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 Class A 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 Class A ordinary shares issuable upon the exercise of the warrants is not current or if the Class A 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 (and his, her or its affiliates) would not be able to exercise their warrants to the extent that, after giving effect to such exercise, such holder (and his, her or its affiliates) would beneficially own in excess of 9.8% of the Class A ordinary shares issued and outstanding. Notwithstanding the foregoing, any person who acquires a warrant with the purpose or effect of changing or influencing the control of our company, or in connection with or as a participant in any transaction having such purpose or effect, immediately upon such acquisition will be deemed to be the beneficial owner of the underlying Class A ordinary shares and not be able to take advantage of this provision.

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 (as a result of a subsequent capitalization of shares payable in Class A ordinary shares, or by a split up of the Class A ordinary shares or other similar event), we will, upon exercise, round up or down to the nearest whole number the number of Class A ordinary shares to be issued to the warrant holder.
