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 March 29, 2022, AIB 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 right (as defined below), with each right entitling the holder thereof to receive one-tenth (1/10) of one Class A ordinary share upon the consummation of our initial business combination (the “units”), (ii) its Class A ordinary shares, $0.0001 par value per share (“Class A ordinary shares”), and (iii) its rights, with each right entitling the holder thereof to receive one-tenth (1/10) of one Class A ordinary share upon the consummation of our initial business combination (the “rights”).

Pursuant to our second amended and restated memorandum and articles of association, our authorized capital stock consists of 53,000,000 ordinary shares, including 50,000,000 Class A ordinary shares, $0.0001 par value and 3,000,000 Class B ordinary shares, $0.0001 par value, and 1,000,000 undesignated preference 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 second amended and restated memorandum and articles of association and our right 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 right. Each right entitles the holder thereof to receive one-tenth (1/10) of one Class A ordinary share upon the consummation of an initial business combination.

Ordinary Shares

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, except as required by law; provided that, prior to our initial business combination, only holders of our Class B ordinary shares will have the right to vote on the appointment of directors, and holders of a majority of our Class B ordinary shares may remove a member of the board of directors for any reason. 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 Class A ordinary shares and holders of Class B ordinary shares will vote together as a single class. There is no cumulative voting with respect to the appointment of directors, with the result that the holders of more than 50% of the founder shares voted for the appointment of directors can elect all of the directors prior to our initial business combination. 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 as of two business days prior to the consummation of our initial business combination, including interest (which interest shall be net of taxes payable), divided by the number of then issued and outstanding public shares, subject to the limitations described herein. At the completion of our initial business combination, we will be required to purchase any Class A ordinary shares properly delivered for redemption and not withdrawn. Our initial shareholders 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 and any public shares held by them in connection with the completion of our initial business combination. Our directors and officers have also entered into the letter agreement, imposing similar obligations on them with respect to public shares acquired by them, if any. Permitted transferees of our initial shareholders, officers or directors will be subject to the same obligations.

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 second 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,” 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 the business combination. 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 at such time will be 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 herein.

Rights

Each holder of a right will receive one-tenth (1/10) of one Class A ordinary share upon consummation of our initial business combination, even if the holder of such right redeemed all Class A ordinary shares held by him, her or it in connection with the initial business combination or an amendment to our Memorandum and Articles of Association with respect to our pre-business combination activities. No additional consideration will be required to be paid by a holder of rights in order to receive his, her or its additional Class A ordinary shares upon consummation of an initial business combination as the consideration related thereto has been included in the unit purchase price paid for by investors. The shares issuable upon exchange of the rights will be freely tradable (except to the extent held by affiliates of ours).

If we enter into a definitive agreement for a business combination in which we will not be the surviving entity, the definitive agreement will provide for the holders of rights to receive the same per share consideration the holders of the Class A ordinary share will receive in the transaction on an as-converted into ordinary share basis, and each holder of a right will be required to affirmatively convert his, her or its rights in order to receive the 1/10 share underlying each right (without paying any additional consideration) upon consummation of the business combination. More specifically, the right holder will be required to indicate his, her or its election to convert the rights into underlying shares as well as to return the original rights certificates to us. If we are unable to complete an initial business combination within the required time period and we liquidate the funds held in the trust account, holders of rights will not receive any of such funds with respect to their rights, nor will they receive any distribution from our assets held outside of the trust account with respect to such rights, and the rights will expire worthless.

As soon as practicable upon the consummation of our initial business combination, we will direct registered holders of the rights to return their rights to our rights agent. Upon receipt of the rights, the rights agent will issue to the registered holder of such right(s) the number of full Class A ordinary shares to which he, she or it is entitled. We will notify registered holders of the rights to deliver their rights to the rights agent promptly upon consummation of such business combination and have been informed by the rights agent that the process of exchanging their rights for ordinary shares should take no more than a matter of days. The foregoing exchange of rights is solely ministerial in nature and is not intended to provide us with any means of avoiding our obligation to issue the shares underlying the rights upon consummation of our initial business combination. Other than confirming that the rights delivered by a registered holder are valid, we will have no ability to avoid delivery of the shares underlying the rights. Nevertheless, there are no contractual penalties for failure to deliver securities to the holders of the rights upon consummation of an initial business combination. Additionally, in no event will we be required to net cash settle the rights. Accordingly, the rights may expire worthless.

Although a company incorporated in the Cayman Islands may issue fractional shares, it is not our intention to issue any fractional shares upon conversions of the rights. In the event that any holder would otherwise be entitled to any fractional share upon exchange of his, her or its rights, we will reserve the option, to the fullest extent permitted by the Memorandum and Articles of Association, the Act and other applicable law, to deal with any such fractional entitlement at the relevant time as we see fit, which would include the rounding down of any entitlement to receive ordinary shares to the nearest whole share (and in effect extinguishing any fractional entitlement), or the holder being entitled to hold any remaining fractional entitlement (without any share being issued) and to aggregate the same with any future fractional entitlement to receive shares in the Company until the holder is entitled to receive a whole number. Any rounding down and extinguishment may be done with or without any in lieu cash payment or other compensation being made to the holder of the relevant rights, such that value received on exchange of the rights may be considered less than the value that the holder would otherwise expect to receive. All holders of rights shall be treated in the same manner with respect to the issuance of shares upon conversions of the rights.
