Exhibit 4.5

DESCRIPTION OF SECURITIES

General

As of March 31, 2026, pursuant to our second amended and restated memorandum and articles of association, our authorized share capital consists of $50,000 divided into 490,000,000 ordinary shares, par value $0.0001 per share and 10,000,000 preference shares, par value $0.0001 per share. As of such date, there were 7,658,348 ordinary shares issued and outstanding (prior to giving effect to the redemption of 2,437,288 ordinary shares following the extraordinary general meeting of shareholders held on such date).

The following description summarizes the material terms of our securities. Because it is only a summary, it may not contain all the information that is important to you. For a complete description you should refer to our amended and restated memorandum and articles of associations and rights agreement, each of which has been filed with the U.S. Securities and Exchange Commission (the “SEC”), and to the applicable provisions of Cayman Islands law.

Public Units

Each unit consists of one ordinary share and right to receive one-fifth of an ordinary share upon the consummation of an initial business combination.

Private Units

The private units (including the rights) will not be transferable, assignable or salable until after the completion of our initial business combination. Otherwise, the private units have terms and provisions that are identical the public units, except that the private units are entitled to registration rights.

Ordinary Shares

Ordinary shareholders of record are entitled to one vote for each share held on all matters to be voted on by shareholders and vote together as a single class, except as required by law. Unless specified in the Companies Act, our Amended and Restated Memorandum and Articles of Association or applicable stock exchange rules, an ordinary resolution is required to approve any such matter voted on by our shareholders which requires the affirmative vote of at least a majority of the votes cast by the shareholders of the issued shares present in person or represented by proxy and entitled to vote on such matter at a general meeting of the company. Approval of certain actions will require a special resolution under Cayman Islands law 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.

In accordance with NASDAQ corporate governance requirements, we are not required to hold an annual general meeting until one year after our first fiscal year end following our listing on NASDAQ. There is no requirement under the Companies Act for us to hold annual or extraordinary general meetings or appoint directors. We may not hold an annual general meeting to appoint new directors prior to the consummation of our initial business combination.

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 income taxes payable) divided by the number of then issued and outstanding public shares, subject to the limitations described herein. The amount in the trust account is initially anticipated to be approximately $10.00 per public share (subject to increase of in the event that our sponsor elects to extend the period of time to consummate a business combination). Our sponsor, officers and directors 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, private placement shares and public shares in connection with the completion of our initial business combination.

Pursuant to the amendment to our Amended and Restated Memorandum and Articles of Association, approved on March 31, 2026, if we are unable to complete our initial business combination within 12 months from the closing of this offering (or up to 24 months from the closing of this offering if we extend the period of time to consummate a business combination, as described in more detail in this prospectus), we will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but no more than ten business days thereafter, subject to lawfully available funds therefor, redeem 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 (which interest shall be net of income taxes payable) 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 sponsor, officers and directors have entered into a letter agreement with us, pursuant to which they have agreed to waive their rights to liquidating distributions from the trust account with respect to their founder shares and private placement shares if we fail to complete our initial business combination within 12 months from the closing of this offering (or up to 24 months from the closing of this offering if we extend the period of time to consummate a business combination, as described in more detail in this prospectus). However, if our sponsor acquires public shares after this offering, they will be entitled to liquidating distributions from the trust account with respect to such public shares if we fail to complete our initial business combination within the prescribed time period.

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 pre-emptive 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 income taxes payable) upon the completion of our initial business combination.

Under Cayman Islands law, we must keep a register of members and there shall be entered therein:

For these purposes, “voting rights” means rights conferred on shareholders in respect of their shares to vote at general meetings of the company on all or substantially all matters. A voting right is conditional where the voting right arises only in certain circumstances.

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 shall 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 this public offering, the register of members shall be immediately updated to reflect the issue of shares by us. Once our register of members has been updated, the shareholders recorded in the register of members shall be deemed to have legal title to the shares set against their name. However, there are certain limited circumstances where an application may be made to a Cayman Islands court for a determination on whether the register of members reflects the correct legal position. Further, the Cayman Islands court has the power to order that the register of members maintained by a company should be rectified where it considers that the register of members does not reflect the correct legal position. If an application for an order for rectification of the register of members were made in respect of our ordinary shares, then the validity of such shares may be subject to re-examination by a Cayman Islands court.

Preference shares

Our amended and restated memorandum and articles of association provides that up to 10,000,000 preference shares may be issued from time to time in one or more series. Our Board of Directors will be authorized to fix the voting rights, if any, designations, powers, preferences, the relative, participating, optional or other special rights and any qualifications, limitations and restrictions thereof, applicable to the shares of each series. Our Board of Directors will be able to, without shareholder approval, issue preference shares with voting and other rights that could adversely affect the voting power and other rights of the holders of the ordinary shares and could have anti-takeover effects. The ability of our Board of Directors to issue preference shares without shareholder approval could have the effect of delaying, deferring or preventing a change of control of us or the removal of existing management. We have no preference shares outstanding at the date hereof. Although we do not currently intend to issue any preference shares, we cannot assure you that we will not do so in the future. No preference shares were issued or registered in the Company’s initial public offering.

Private shares

The private shares are identical to the ordinary shares sold in the initial public offering, except that (i) the private shares are subject to certain transfer restrictions, as described in more detail below and (ii) our sponsor, officers and directors have agreed (A) to waive their redemption rights with respect to their private shares in connection with the completion of our initial business combination, (B) to waive their redemption rights with respect to any private shares held by them in connection with a shareholder vote to approve an amendment to our amended and restated memorandum and articles of association (x) to modify the substance or timing of our obligation to provide for the redemption of our public shares in connection with an initial business combination or to redeem 100% of our public shares if we have not consummated our initial business combination within the timeframe set forth therein or (y) with respect to any other provision relating to shareholders’ rights or pre-initial business combination activity and (C) to waive their rights to liquidating distributions from the trust account with respect to their private shares if we fail to complete our initial business combination within 12 months from the closing of this offering (or up to 24 months from the closing of the initial public offering if we extend the period of time to consummate a business combination, 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 such time period. If we submit our initial business combination to our public shareholders for a vote, our sponsor, officers and directors have agreed (and their permitted transferees will agree), pursuant to the terms of a letter agreement entered into with us, to vote any private shares held by them and any public shares purchased during or after this offering in favor of our initial business combination.

Rights

If we enter into a definitive agreement for a business combination in which we will be the surviving entity, each holder of a right will receive one-fifth (1/5) of one ordinary share upon consummation of our initial business combination, even if the holder of such right redeemed 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. 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 as the consideration related thereto has been included in the unit purchase price paid for by investors in this offering. 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 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 1/5 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. In the event that we are not the surviving entity upon the consummation of our initial business combination, and there is no effective registration statement for the offering of the shares underlying the rights, the rights may expire worthless.

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 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 amended and restated memorandum and articles of association, the Companies 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.

The rights will be issued in registered form under a rights agreement between Continental Stock Transfer & Trust Company, as rights agent, and us.

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 cash dividends subsequent to a business combination will be within the discretion of our Board of Directors at such time and we will only pay such dividends out of our profits or share premium (subject to solvency requirements) as permitted under Cayman Islands law. 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. Further, if we incur any indebtedness, our ability to declare dividends may be limited by restrictive covenants we may agree to in connection therewith.

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 Nasdaq Capital Market under the symbols “UYSCU,” “UYSC” and “UYSCR,” respectively.

Limitation on Liability and Indemnification of Officers and Directors

Cayman Islands law does not limit the extent to which a company’s memorandum and articles of association may provide for indemnification of officers and directors, except to the extent any such provision may be held by the Cayman Islands courts to be contrary to public policy, such as to provide indemnification against willful default, fraud or the consequences of committing a crime. Our Amended and Restated Memorandum and Articles of Association provides for indemnification of our officers and directors to the maximum extent permitted by law, including for any liability incurred in their capacities as such, except through their own actual fraud, willful default or willful neglect. We may purchase a policy of directors’ and officers’ liability insurance that insures our officers and directors against the cost of defense, settlement or payment of a judgment in some circumstances and insures us against our obligations to indemnify our officers and directors.

We entered into agreements with our officers and directors to provide contractual indemnification in addition to the indemnification provided for in our amended and restated memorandum and articles of association. Our amended and restated memorandum and articles of association also permit us to maintain insurance on behalf of any officer, director or employee for any liability arising out of his or her actions. We also will obtain a policy of directors’ and officers’ liability insurance that insures our officers and directors against the cost of defense, settlement or payment of a judgment in some circumstances and insures us against our obligations to indemnify our officers and directors.

These provisions may discourage shareholders from bringing a lawsuit against our directors for breach of their fiduciary duty. These provisions also may have the effect of reducing the likelihood of derivative litigation against directors and officers, even though such an action, if successful, might otherwise benefit us and our shareholders. Furthermore, a shareholder’s investment may be adversely affected to the extent we pay the costs of settlement and damage awards against officers and directors pursuant to these indemnification provisions. We believe that these provisions, the insurance and the indemnity agreements are necessary to attract and retain talented and experienced officers and directors.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling us pursuant to the foregoing provisions, we have been informed that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.
