Description of Registrant's Securities

Exhibit 4.5

DESCRIPTION OF SECURITIES

The following summary of the registered securities of DT Cloud Star Acquisition Corporation, a Cayman Islands exempted company (the “Company,” “we,” “our,” and “us), does not purport to be complete and is qualified in its entirety by reference to our amended and restated memorandum and articles of association, which is incorporated by reference as Exhibit 4.5 to our Annual Report on Form 10-K for the year ended December 31, 2024 (the “Report”) of which this Exhibit is a part, and applicable Cayman Islands law. We urge you to read our amended and restated memorandum and articles of association for a complete description of the rights and preferences of our securities. Terms used herein and not defined herein shall have the meaning ascribed to such terms in the Report.

We are a Cayman Islands exempted company (company number 396024) and our affairs are governed by our amended and restated memorandum and articles of association, the Companies Act and common law of the Cayman Islands. Based upon our amended and restated memorandum and articles of association, our share capital is $50,000 divided into 500,000,000 shares of par value of $0.0001 each. No preferred shares are issued or outstanding or authorized by our constitutional documents. The following description summarizes the material terms of our shares as set out more particularly in our 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-nineth (1/9) of one ordinary share upon the consummation of an initial business combination. Each right entitles the holder thereof to receive one-nineth (1/9) 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 either be rounded down to the nearest whole share or otherwise addressed in accordance with the applicable provisions of Cayman Islands Law. As a result, you must hold rights in multiples of nine in order to receive shares for all of your rights upon closing of a business combination.

Our units, each consisting of one ordinary share and one right to receive one-nineth (1/9) of one ordinary share, began trading on The Nasdaq Stock Market LLC (“Nasdaq”) on July 25, 2024. The ordinary shares and rights comprising the units began to trade separately on September 16, 2024. As of June 30, 2024, the last business day of the registrant’s most recently completed second fiscal quarter, the registrant’s securities were not publicly traded.

Additionally, the units not separated prior to the completion of our initial business combination will automatically separate into their component parts and will not be traded after the completion of our initial business combination.

Ordinary Shares

As of March 25, 2025, there were 8,900,900 ordinary shares of the Company, par value $0.0001 per share, issued and outstanding.

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 respective ordinary shares owned by them immediately prior to our initial public offering and any shares purchased in our initial public offering or following our initial public offering in the open market in favor of the proposed business combination.

At least five (5) 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 serve until the next annual general meeting. There is no cumulative voting with respect to the election of directors. After the closing of a Business Combination, the Company may by Ordinary Resolution appoint any person to be a director or may by Ordinary Resolution remove any director.

Pursuant to our amended and restated memorandum and articles of association, if we do not consummate a business combination by 15 months from the closing of 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, 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 us to pay our income taxes, divided by the number of the then-outstanding public shares, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any); 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 the case of clauses (ii) and (iii) 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 insider 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 the Companies Act, the ordinary shares are deemed to be issued when the name of the shareholder is entered in our register of members. Our register of members will be maintained by our transfer agent VStock Transfer LLC, which will enter the name of Cede & Co in our register of members on the closing of our initial public offering as nominee for each of the respective public shareholders. 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 a right will automatically receive one-ninth (1/9) of one 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 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 nine rights will be required to affirmatively convert his, her or its rights in order to receive the one share underlying each right 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 either be rounded down to the nearest whole share or otherwise addressed in accordance with the applicable provisions of Cayman Islands Law. As a result, you must hold rights in multiples of nine 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 Warrant Agent

The transfer agent for our ordinary shares and rights agent for our rights is VStock Transfer LLC, 18 Lafayette Place, Woodmere, New York, NY 11598.

Listing of our Securities

Our units have been approved for listing on Nasdaq under the symbols “DTSQU,” “DTSQ,” and “DTSQR,” respectively. Our units began trading on Nasdaq on July 25, 2024. The ordinary shares and rights comprising the units began to trade separately on September 16, 2024.

Certain Differences in Corporate Law

Cayman Islands companies are governed by the Companies Act. The Companies Act is modeled on English Law but does not follow recent English Law statutory enactments, and differs from laws applicable to United States corporations and their shareholders. Set forth below is a summary of the provisions of the Companies Act applicable to us that materially differ from the laws applicable to companies incorporated in the United States and their shareholders.

Mergers and Similar Arrangements. In certain circumstances, the Companies Act allows for mergers or consolidations between two Cayman Islands companies, or between a Cayman Islands exempted company and a company incorporated in another jurisdiction (provided that is facilitated by the laws of that other jurisdiction) so as to form a single surviving company.

Where the merger or consolidation is between two Cayman Islands companies, the directors of each company must approve a written plan of merger or consolidation containing certain prescribed information. That plan or merger or consolidation must then be authorized by either (a) a special resolution (usually a majority of two-thirds of the votes of shareholders who attend and vote at a general meeting) of the shareholders of each company; or (b) such other authorization, if any, as may be specified in such constituent company’s articles of association. No shareholder resolution is required for a merger between a parent company (i.e., a company that owns at least 90% of the votes at a general meeting in a subsidiary company) and its subsidiary company. The consent of each holder of a fixed or floating security interest of a constituent company must be obtained, unless the court waives such requirement. If the Cayman Islands Registrar of Companies is satisfied that the requirements of the Companies Act (which includes certain other formalities) have been complied with, the Registrar of Companies will register the plan of merger or consolidation.

Where the merger or consolidation involves a foreign company, the procedure is similar, save that with respect to the foreign company, the directors of the Cayman Islands exempted company are required to make a declaration to the effect that, having made due enquiry, they are of the opinion that the requirements set out below have been met: (i) that the merger or consolidation is permitted or not prohibited by the constitutional documents of the foreign company and by the laws of the jurisdiction in which the foreign company is incorporated, and that those laws and any requirements of those constitutional documents have been or will be complied with; (ii) that no petition or other similar proceeding has been filed and remains outstanding or order made or resolution adopted to wind up or liquidate the foreign company in any jurisdictions; (iii) that no receiver, trustee, administrator or other similar person has been appointed in any jurisdiction and is acting in respect of the foreign company, its affairs or its property or any part thereof; (iv) that no scheme, order, compromise or other similar arrangement has been entered into or made in any jurisdiction whereby the rights of creditors of the foreign company are and continue to be suspended or restricted.

Where the surviving company is the Cayman Islands exempted company, the directors of the Cayman Islands exempted company are further required to make a declaration to the effect that, having made due enquiry, they are of the opinion that the requirements set out below have been met: (i) that the foreign company is able to pay its debts as they fall due and that the merger or consolidation is bona fide and not intended to defraud unsecured creditors of the foreign company; (ii) that in respect of the transfer of any security interest granted by the foreign company to the surviving or consolidated company (a) consent or approval to the transfer has been obtained, released or waived; (b) the transfer is permitted by and has been approved in accordance with the constitutional documents of the foreign company; and (c) the laws of the jurisdiction of the foreign company with respect to the transfer have been or will be complied with; (iii) that the foreign company will, upon the merger or consolidation becoming effective, cease to be incorporated, registered or exist under the laws of the relevant foreign jurisdiction; and (iv) that there is no other reason why it would be against the public interest to permit the merger or consolidation.

Where the above procedures are adopted, the Companies Act provides for a right of dissenting shareholders to be paid a payment of the fair value of his, her or its shares upon their dissenting to the merger or consolidation if they follow a prescribed procedure. In essence, that procedure is as follows (a) the shareholder must give his written objection to the merger or consolidation to the constituent company before the vote on the merger or consolidation, including a statement that the shareholder proposes to demand payment for his shares if the merger or consolidation is authorized by the vote; (b) within 20 days following the date on which the merger or consolidation is approved by the shareholders, the constituent company must give written notice to each shareholder who made a written objection; (c) a shareholder must within 20 days following receipt of such notice from the constituent company, give the constituent company a written notice of his intention to dissent including, among other details, a demand for payment of the fair value of his shares; (d) within seven days following the date of the expiration of the period set out in paragraph (b) above or seven days following the date on which the plan of merger or consolidation is filed, whichever is later, the constituent company, the surviving company or the consolidated company must make a written offer to each dissenting shareholder to purchase his shares at a price that the company determines is the fair value and if the company and the shareholder agree the price within 30 days following the date on which the offer was made, the company must pay the shareholder such amount; (e) if the company and the shareholder fail to agree a price within such 30-day period, within 20 days following the date on which such 30-day period expires, the company must (and any dissenting shareholder may) file a petition with the Cayman Islands Grand Court to determine the fair value and such petition must be accompanied by a list of the names and addresses of the dissenting shareholders with whom agreements as to the fair value of their shares have not been reached by the company. At the hearing of that petition, the court has the power to determine the fair value of the shares together with a fair rate of interest, if any, to be paid by the company upon the amount determined to be the fair value. Any dissenting shareholder whose name appears on the list filed by the company may participate fully in all proceedings until the determination of fair value is reached. These rights of a dissenting shareholder are not be available in certain circumstances, for example, to dissenters holding shares of any class in respect of which an open market exists on a recognized stock exchange or recognized interdealer quotation system at the relevant date or where the consideration for such shares to be contributed are shares of any company listed on a national securities exchange or shares of the surviving or consolidated company.

Moreover, Cayman Islands law also has separate statutory provisions that facilitate the reconstruction or amalgamation of companies in certain circumstances, schemes of arrangement will generally be more suited for complex mergers or other transactions involving widely held companies, commonly referred to in the Cayman Islands as a “scheme of arrangement” which may be tantamount to a merger. In the event that a merger was sought pursuant to a scheme of arrangement (the procedure of which are more rigorous and take longer to complete than the procedures typically required to consummate a merger in the United States), the arrangement in question must be approved by a seventy-five percent (75%) in value of the shareholders or class of shareholders, as the case may be, that are present and voting either in person or by proxy at a meeting, or meeting summoned for that purpose. The convening of the meetings and subsequently the terms of the arrangement must be sanctioned by the Grand Court of the Cayman Islands. While a dissenting shareholder would have the right to express to the court the view that the transaction should not be approved, the court can be expected to approve the arrangement if it satisfies itself that:

If a scheme of arrangement or takeover offer (as described below) is approved, any dissenting shareholder would have no rights comparable to appraisal rights, which would otherwise ordinarily be available to dissenting shareholders of United States corporations, providing rights to receive payment in cash for the judicially determined value of the shares.

Squeeze-out Provisions. When a takeover offer is made and accepted by holders of 90% of the shares to whom the offer relates is made within four months after making such offer, the offeror may, within a two-month period, require the holders of the remaining shares to transfer such shares on the terms of the offer. An objection can be made to the Grand Court of the Cayman Islands but this is unlikely to succeed unless there is evidence of fraud, bad faith, collusion or inequitable treatment of the shareholders.

Further, transactions similar to a merger, reconstruction and/or an amalgamation may in some circumstances be achieved through other means to these statutory provisions, such as a share capital exchange, asset acquisition or control, through contractual arrangements, of an operating business.

Shareholders’ Suits. In principle, we will normally be the proper plaintiff to sue for a wrong done to us as a company and as a general rule, a derivative action may not be brought by a minority shareholder. However, based on English law authorities, which would in all likelihood be of persuasive authority in the Cayman Islands, the Cayman Islands courts can be expected to follow and apply the common law principles (namely the rule in Foss v. Harbottle and the exceptions thereto) so that a non-controlling shareholder may be permitted to commence a class action against or derivative actions in the name of the company to challenge:

Enforcement of Civil Liabilities. The Cayman Islands has a different body of securities laws as compared to the United States and provides less protection to investors. Additionally, Cayman Islands companies may not have standing to sue before the Federal courts of the United States.

We have been advised by our Cayman Islands legal counsel that there is uncertainty as to whether the courts of the Cayman Islands would (i) recognize or enforce against us judgments of courts of the United States based on certain civil liability provisions of U.S. securities laws; and (ii) entertain original actions brought in each respective jurisdiction against us or our directors or officers predicated upon the securities laws of the United States or any state in the United States.

There is no statutory enforcement in the Cayman Islands of judgments obtained in the United States, although the courts of the Cayman Islands will in certain circumstances recognize and enforce a foreign judgment, without any re-examination or re-litigation of matters adjudicated upon, provided such judgment:

Subject to the above limitations, in appropriate circumstances, a Cayman Islands court may give effect in the Cayman Islands to other kinds of final foreign judgments such as declaratory orders, orders for performance of contracts and injunctions.

Special Considerations for Exempted Companies. We are an exempted company with limited liability (meaning our public shareholders have no liability, as members of the company, for liabilities of the company over and above the amount paid for their shares) under the Companies Act. The Companies Act distinguishes between ordinary resident companies and exempted companies. Any company that is registered in the Cayman Islands but conducts business mainly outside of the Cayman Islands may apply to be registered as an exempted company. The requirements for an exempted company are essentially the same as for an ordinary company except for the exemptions and privileges listed below:

Our Amended and Restated Memorandum and Articles of Association

Our amended and restated memorandum and articles of association, as currently in effect, contain 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 amended and restated memorandum and articles of association provide 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, who currently beneficially owns approximately 21.7% of our ordinary shares (including ownership of the private placement units), will participate in any vote to amend our amended and restated memorandum and articles of association and will have the discretion to vote in any manner it chooses. Specifically, our amended and restated memorandum and articles of association provide, among other things, that:

In addition, our amended and restated memorandum and articles of association provide that under no circumstances will we redeem our public shares in an amount that would cause our net tangible assets to be less than $5,000,001 either immediately prior to or upon consummation of our initial business combination, after payment of the deferred underwriting commission.

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 but, provided 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 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 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.
