EXHIBIT 4.5

DESCRIPTION OF SECURITIES REGISTERED UNDER SECTION 12 OF THE SECURITIES EXCHANGE ACT OF 1934

The following summary of the material terms of our securities is not intended to be a complete summary of the rights and preferences of such securities and is qualified in its entirety by reference to our second amended and restated memorandum and articles of association, the rights agreement and the other documents filed as exhibits to the Annual Report on Form 10-K of which this exhibit is a part. We urge you to read those documents for a complete description of the rights and preferences of our securities. Capitalized terms used but not defined in this exhibit have the meanings given to them in the Annual Report on Form 10-K.

As of the date of the Annual Report on Form 10-K of which this exhibit is a part, we had three classes of securities registered under Section 12 of the Exchange Act: units, each consisting of one ordinary share and one right to receive one-fourth (1/4) of one ordinary share upon the consummation of our initial business combination; ordinary shares, par value $0.0001 per share; and rights, each entitling the holder to receive one-fourth (1/4) of one ordinary share upon the consummation of our initial business combination. As of October 27, 2026, there were 14,637,000 ordinary shares issued and outstanding, including 11,500,000 public shares, 2,875,000 founder shares, 212,000 private shares and 50,000 representative shares, and 11,712,000 rights outstanding, consisting of 11,500,000 public rights and 212,000 private rights.

General

We are a Cayman Islands exempted company and our affairs are governed by our second amended and restated memorandum and articles of association that became effective on February 25, 2026, the Companies Act and common law of the Cayman Islands. Pursuant to our second amended and restated memorandum and articles of association, our authorized share capital is $60,000 divided into 600,000,000 ordinary shares of par value of $0.0001 each. The following description summarizes the material terms of our shares as set out more particularly in our second amended and restated memorandum and articles of association. Because it is only a summary, it may not contain all the information that is important to you.

Units

Each unit consists of one ordinary share and one right to receive one-fourth (1/4) of one ordinary share upon the consummation of an initial business combination. Each right entitles the holder thereof to receive one-fourth (1/4) of an ordinary share upon consummation of our initial business combination. In addition, we will not issue fractional shares in connection with an exchange of rights. Fractional shares will be rounded down to the nearest whole share. As a result, you must hold rights in multiples of four in order to receive shares for all of your rights upon closing of a business combination.

Our ordinary shares and rights began separate trading on the NYSE on April 20, 2026.

Ordinary Shares

Our shareholders of record are entitled to one vote for each share held on all matters to be voted on by shareholders. In connection with any vote held to approve our initial business combination, all of our initial shareholders, as well as all of our officers and directors, have agreed to vote their founder shares, private shares and any public shares acquired in or after our initial public offering (including in open market and privately-negotiated transactions, aside from shares they may purchase in compliance with the requirements of Rule 14e-5 under the Exchange Act, which would not be voted in favor of approving the business combination transaction) in favor of the proposed business combination.

If we seek shareholder approval, we will proceed with the business combination only if we obtain the approval of an ordinary resolution under Cayman Islands law, which requires the affirmative vote of a majority of the shareholders who attended and voted at a general meeting of the Company. At least five (5) clear days’ notice must be given for each general meeting (although we will provide whatever minimum number of days are required under federal securities laws). Shareholders may vote at meetings in person or by proxy.

The members of our board of directors shall hold office until the expiration of their respective terms of office and until their successors shall have been elected and qualified. There is no cumulative voting with respect to the election of directors. After the closing of a Business Combination, the company may by an Ordinary Resolution appoint any person to be a director or may by Ordinary Resolution remove any director.

Pursuant to our second amended and restated memorandum and articles of association, if we do not consummate a business combination by 15 months from the effective date of the registration statement for our initial public offering, we will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, subject to lawfully available funds therefor, redeem 100% of 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 and not previously released to the company (less taxes payable and up to $100,000 of interest to pay dissolution expenses) divided by the number of then issued and outstanding public shares, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of our remaining shareholders and our board of directors, liquidate and dissolve, subject in each case to our obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. Our initial shareholders have agreed to waive their rights to share in any distribution from the trust account with respect to their founder shares upon our winding up, liquidation and subsequent dissolution.

Our shareholders have no conversion, preemptive or other subscription rights and there are no sinking fund or redemption provisions applicable to the ordinary shares, except that public shareholders have the right to have their public shares converted to cash equal to their pro rata share of the trust account if they vote on the proposed business combination and the business combination is completed.

Register of Members

Under Cayman Islands law, the register of members of our company is prima facie evidence of the matters set out therein (i.e., the register of members will raise a presumption of fact on the matters referred to above unless rebutted) and a member registered in the register of members will be deemed as a matter of Cayman Islands law to have legal title to the shares as set against its name in the register of members. Upon the closing of our initial public offering, the register of members will be immediately updated to record and give effect to the issuance of shares by us to the custodian or its nominee. Once our register of members has been updated, the shareholders recorded in the register of members will be deemed to have legal title to the shares set against their name. If (a) information that is required to be entered in the register of members is omitted from the register or is inaccurately entered in the register, or (b) there is unreasonable delay in entering information in the register, a shareholder of the company, or any person who is aggrieved by the omission, inaccuracy or delay, may apply to the Cayman Islands courts for an order that the register be rectified, and the court may either refuse the application or order the rectification of the register, and may direct the company to pay all costs of the application and any damages the applicant may have sustained.

Rights

Except in cases where we are not the surviving company in a business combination, each holder of four rights will automatically receive one ordinary share upon consummation of our initial business combination, even if the holder of a public right converted all ordinary shares held by him, her or it in connection with the initial business combination or an amendment to our second amended and restated memorandum and articles of association with respect to our pre-business combination activities. In the event we will not be the surviving company upon completion of our initial business combination, each holder of four rights will be required to affirmatively convert his, her or its rights in order to receive the shares underlying the rights upon consummation of the business combination. No additional consideration will be required to be paid by a holder of rights in order to receive his, her or its additional ordinary shares upon consummation of an initial business combination. 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 ordinary shares will receive in the transaction on an as-converted into ordinary shares basis.

We will not issue fractional shares in connection with an exchange of rights. Fractional shares will be rounded down to the nearest whole share. As a result, you must hold rights in multiples of four in order to receive shares for all of your rights upon closing of a business combination. 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. Further, 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.

Dividends

We have not paid any cash dividends on our ordinary shares 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 condition subsequent to completion of a business combination. The payment of any dividends subsequent to a business combination will be within the discretion of our then board of directors. It is the present intention of our board of directors to retain all earnings, if any, for use in our business operations and, accordingly, our board does not anticipate declaring any dividends in the foreseeable future.

Our Transfer Agent and Rights Agent

The transfer agent for our ordinary shares and rights agent for our rights is Continental Stock Transfer & Trust Company.

Listing of our Securities

Our units, ordinary shares and rights are listed on the NYSE under the symbols “TRADU,” “TRAD” and “TRADR,” respectively. Our units began trading on the NYSE on February 26, 2026, and our ordinary shares and rights began separate trading on the NYSE on April 20, 2026. We cannot assure you that our securities will continue to be listed on the NYSE, as we may not meet certain continued listing standards.

Our Second Amended and Restated Memorandum and Articles of Association

Our second amended and restated memorandum and articles of association contains certain requirements and restrictions relating to our initial public offering that apply to us until the completion of our initial business combination. These provisions cannot be amended without a special resolution. As a matter of Cayman Islands law, a resolution is deemed to be a special resolution where it has been approved by either (i) at least two-thirds (or any higher threshold specified in a company’s articles of association) of a company’s shareholders who, being entitled to do so, attend and vote at a general meeting for which notice specifying the intention to propose the resolution as a special resolution has been given; or (ii) if so authorized by a company’s articles of association, by a unanimous written resolution of all of the company’s shareholders. Our second amended and restated memorandum and articles of association provides that special resolutions must be approved either by at least two-thirds of our shareholders who, being entitled to do so, attend and vote at a general meeting for which notice specifying the intention to propose the resolution as a special resolution has been given (i.e., the lowest threshold permissible under Cayman Islands law), or by a unanimous written resolution of all of our shareholders.

Our Sponsor, which beneficially owns 3,087,000 of our issued and outstanding ordinary shares, consisting of 2,875,000 founder shares and 212,000 private shares, may participate in any vote to amend our second amended and restated memorandum and articles of association and has the discretion to vote in any manner it chooses. Specifically, our second amended and restated memorandum and articles of association provides, among other things, that:

The Companies Act permits a company incorporated in the Cayman Islands to amend its memorandum and articles of association with the approval of a special resolution which requires the approval of the holders of at least two-thirds of such company’s shareholders who, being entitled to do so, attend and vote at a general meeting or by way of unanimous written resolution. A company’s articles of association may specify that the approval of a higher majority is required; however, provided that the approval of the required majority is obtained, any Cayman Islands exempted company may amend its memorandum and articles of association regardless of whether its memorandum and articles of association provides otherwise. Accordingly, although we could amend any of the provisions relating to our proposed offering, structure and business plan which are contained in our second amended and restated memorandum and articles of association, we view all of these provisions as binding obligations to our shareholders and neither we, nor our officers or directors, will take any action to amend or waive any of these provisions unless we provide dissenting public shareholders with the opportunity to redeem their public shares.

Certain Anti-Takeover Provisions of our Second Amended and Restated Memorandum and Articles of Association

Our authorized but unissued ordinary shares are available for future issuances without shareholder 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 ordinary shares could render more difficult or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger or otherwise.

Anti- Money Laundering - Cayman Islands

In order to comply with legislation or regulations aimed at the prevention of money laundering, we are required to adopt and maintain anti-money laundering procedures and may require subscribers to provide evidence to verify their identity and source of funds. Where permitted, and subject to certain conditions, we may also delegate the maintenance of our anti -money laundering procedures (including the acquisition of due diligence information) to a suitable person. We reserve the right to request such information as is necessary to verify the identity of a subscriber. In some cases, the directors may be satisfied that no further information is required since an exemption applies under the Anti -Money Laundering Regulations (As Revised) of the Cayman Islands, as amended and revised from time to time (the “Regulations”) or any other applicable law. Depending on the circumstances of each application, a detailed verification of identity might not be required where: (a) the subscriber makes the payment for their investment from an account held in the subscriber’s name at a recognized financial institution; or (b) the subscriber is regulated by a recognized regulatory authority and is based or incorporated in, or formed under the law of, a recognized jurisdiction; or (c) the application is made through an intermediary which is regulated by a recognized regulatory authority and is based in or incorporated in, or formed under the law of a recognized jurisdiction and an assurance is provided in relation to the procedures undertaken on the underlying investors.

For the purposes of these exceptions, recognition of a financial institution, regulatory authority or jurisdiction will be determined in accordance with the Regulations by reference to those jurisdictions recognized by the Cayman Islands Monetary Authority as having equivalent anti-money laundering regulations. In the event of delay or failure on the part of the subscriber in producing any information required for verification purposes, we may refuse to accept the application, in which case any funds received will be returned without interest to the account from which they were originally debited. We also reserve the right to refuse to make any payment to a shareholder if our directors or officers suspect or are advised that the payment to such shareholder might result in a breach of applicable anti -money laundering or other laws or regulations by any person in any relevant jurisdiction, or if such refusal is considered necessary or appropriate to ensure our compliance with any such laws or regulations in any applicable jurisdiction.

If any person in the Cayman Islands knows or suspects or has reasonable grounds for knowing or suspecting that another person is engaged in criminal conduct or money laundering or is involved with terrorism or terrorist financing and property and the information for that knowledge or suspicion came to their attention in the course of business in the regulated sector, or other trade, profession, business or employment, the person will be required to report such knowledge or suspicion to (i) the Financial Reporting Authority (“FRA”) of the Cayman Islands, pursuant to the Proceeds of Crime Act (As Revised) of the Cayman Islands if the disclosure relates to criminal conduct or money laundering, or (ii) a police officer of the rank of constable or higher, or the FRA, pursuant to the Terrorism Act (As Revised) of the Cayman Islands, if the disclosure relates to involvement with terrorism or terrorist financing and property. Such a report shall not be treated as a breach of confidence or of any restriction upon the disclosure of information imposed by any enactment or otherwise.
