Exhibit 4.5

DESCRIPTION OF SECURITIES

General

As of March 30, 2026 (the “Reference Date”), pursuant to our amended and restated memorandum and articles of association, our authorized share capital consists of $5,550 divided into 55,000,000 ordinary shares of a par value of $0.0001 each and 500,000 preference shares of a par value of $0.0001 each. As of the Reference Date, 5,951,030 ordinary shares are issued and outstanding. No preference shares are currently outstanding.

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 one right. Each right entitles the holder thereof to receive one-tenth of one ordinary share upon the consummation of an initial business combination.

Private Units

The private units (including the private rights) will not be transferable, assignable or salable until 30 days after the completion of our initial business combination (except as described herein). Otherwise, the private units are identical to the units sold in the IPO except that the private units will be entitled to registration rights.

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, 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 the IPO and any shares purchased in the IPO or following the IPO in the open market (to the extent permitted under applicable securities laws and the limitations described in the Prospectus) in favor of the proposed business combination.

We will proceed with the business combination only if we have net tangible assets of at least $5,000,001 (after payment of deferred underwriting discounts, and net of taxes payable on the income earned on the trust account and funds previously released to the company to pay our taxes or for use as working capital) either immediately prior to or upon consummation of such business combination, or otherwise we are exempt from the provisions of Rule 419 promulgated under the Securities Act (so that we are not subject to the SEC’s “penny stock” rules), and solely if we seek shareholder approval, a majority of the issued and outstanding ordinary shares voted are voted in favor of the business combination.

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.

Pursuant to our amended and restated memorandum and articles of association, if we do not consummate a business combination by 15 months from the consummation of the IPO (or up to 21 months from the closing of the IPO if we extend the period of time to consummate a business combination by the full amount of time, as described in more detail in the Prospectus), we will redeem 100% of the public shares sold in the IPO. The per-share amount we will distribute to investors who properly redeem their shares will not be reduced by the deferred underwriting discounts we will pay to the underwriters. Our initial shareholders have agreed to waive their rights to share in any distribution from the trust account with respect to their founders’ shares upon our winding up, dissolution and liquidation. They will, however, participate in any liquidation distribution from the trust account with respect to any ordinary shares acquired in, or following, the IPO.

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 sell their shares to us in a tender offer or have their ordinary shares redeemed for cash equal to their pro rata share of the trust account if they vote on the proposed business combination in connection with such business combination and the business combination is completed.

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

(a)

the names and addresses of the members, a statement of the shares held by each member, which: Distinguishes each share by its number (so long as the share has a number), Confirms the amount paid, or agreed to be considered as paid, on the shares of each member, Confirms the number and category of shares held by each member, and Confirms whether each relevant category of shares held by a member carries voting rights under the articles of association, and if so, whether such voting rights are conditional;

(b)

the date on which the name of any person was entered on the register as a member; and

(c)

the date on which any person ceased to be a member.

For these purposes, “voting rights” means rights conferred on shareholders, including the right to appoint or remove directors, 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 will provide that 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 are being issued or registered in the IPO.

Private shares

Except as described in this section, the private shares have terms and provisions that are identical to those of the ordinary shares being sold as part of the units in the IPO.

The private shares will not be transferable, assignable or salable until 30 days after the completion of our initial business combination. The initial shareholders have agreed to (i) waive their redemption rights with respect to their private shares in connection with the completion of our initial business combination, (ii) waive their redemption rights with respect to their private shares in connection with a shareholder vote to approve an amendment to our amended and restated memorandum and articles of association (A) to modify the substance or timing of our obligation to redeem 100% of our public shares if we do not complete our initial business combination within 15 months from the closing of the IPO (or up to 21 months from the closing of the IPO if we extend the period of time to consummate a business combination by the full amount of time, as described in more detail in the Prospectus) or (B) with respect to any other provision relating to shareholders’ rights or pre-initial business combination activity and (iii) 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 15 months from the closing of the IPO (or up to 21 months from the closing of the IPO if we extend the period of time to consummate a business combination by the full amount of time, as described in more detail in the Prospectus). With respect to the private shares held by the underwriters, such shares have been deemed compensation by FINRA and are therefore subject to a lock-up for a period of 180 days immediately following the date of the effectiveness of the registration statement of which the Prospectus forms a part pursuant to Rule 5110(e)(1) of FINRA’s Conduct Rules. Pursuant to FINRA Rule 5110(e)(1), the underwriters’ securities will not be the subject of any hedging, short sale, derivative, put or call transaction that would result in the economic disposition of the securities by any person for a period of 180 days immediately following the effective date of the registration statement of which the Prospectus forms a part, nor may they be sold, transferred, assigned, pledged or hypothecated for a period of 180 days immediately following the effective date of the registration statement of which the Prospectus forms a part except to any underwriter and selected dealer participating in the IPO and their bona fide officers or partners.

Rights included as part of Units

Except in cases where we are not the surviving company in a business combination, each holder of a right will automatically receive one-tenth of 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 amended and restated memorandum and articles of association with respect to our pre-business combination activities. As a result, you must hold ten rights to receive one ordinary share at the closing of the initial business combination. In the event we will not be the surviving company upon completion of our initial business combination, each holder of a right will be required to affirmatively convert his, her or its rights in order to receive the one-tenth of a 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 conversion 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.

The rights will be issued in registered form under a rights agreement between Continental Stock Transfer & Trust Company, as rights agent, and us. The rights agreement provides that the terms of the rights may be amended without the consent of any holder to cure any ambiguity or correct any defective provision, but requires the approval, by written consent or vote, of the holders of a majority of the then outstanding rights in order to make any change that adversely affects the interests of the registered holders.

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 10 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.

We have agreed that, subject to applicable law, any action, proceeding or claim against us arising out of or relating in any way to the rights agreement, including under the Securities Act, will be brought and enforced in the courts of the State of New York or the United States District Court for the Southern District of New York, and we irrevocably submit to such jurisdiction, which jurisdiction will be the exclusive forum for any such action, proceeding or claim. See “Risk Factors — Our rights agreement will designate the courts of the State of New York or the United States District Court for the Southern District of New York as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by holders of our rights, which could limit the ability of rights holders to obtain a favorable judicial forum for disputes with our company.” This provision applies to claims under the Securities Act but does not apply to claims under the Exchange Act or any claim for which the federal district courts of the United States of America are the sole and exclusive forum. We note, however, that there is uncertainty as to whether a court would enforce these provisions and that investors cannot waive compliance with the federal securities laws and the rules and regulations thereunder. Section 22 of the Securities Act creates concurrent jurisdiction for state and federal courts over all suits brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder.

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 our initial business combination. Under the laws of the Cayman Islands a Cayman Islands company may pay a dividend on its shares out of either profit or the share premium account, provided that in no circumstances may a dividend be paid if following such payment the company would be unable to pay its debts as they fall due in the ordinary course of business. 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 our initial business combination. The payment of any dividends subsequent to our initial business combination will be within the discretion of our then board of directors at such time and we will only pay such dividend 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.

Alteration of Share Capital

Subject to the Companies Act, our shareholders may, by ordinary resolution:

(a)

increase our share capital by new shares of the amount fixed by that ordinary resolution and with the attached rights, priorities and privileges set out in that ordinary resolution;

(b)

consolidate and divide all or any of our share capital into shares of larger amount than our existing shares;

(c)

convert all or any of our paid-up shares into stock, and reconvert that stock into paid up shares of any denomination;

(d)

sub-divide our shares or any of them into shares of an amount smaller than that fixed, so, however, that in the sub-division, the proportion between the amount paid and the amount, if any, unpaid on each reduced share shall be the same as it was in case of the share from which the reduced share is derived; and

(e)

cancel shares which, at the date of the passing of that ordinary resolution, have not been taken or agreed to be taken by any person and diminish the amount of our share capital by the amount of the shares so cancelled or, in the case of shares without nominal par value, diminish the number of shares into which our capital is divided.

Subject to the Companies Act and to any rights for the time being conferred on the shareholders holding a particular class of shares, our shareholders may, by special resolution, reduce the share capital of the company.

Listing of our Securities

Our units, ordinary shares and rights are listed on the NASDAQ Capital Market under the symbols “RDACU,” “RDAC” and “RDACR,” 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 or against the indemnified person’s own fraud or dishonesty.

Our amended and restated memorandum and articles of association provides that, subject to certain limitations, the company shall indemnify its directors and officers against all expenses, including legal fees, and against all judgments, fines and amounts paid in settlement and reasonably incurred in connection with legal, administrative or investigative proceedings. Such indemnity only applies if the person acted honestly and in good faith with a view to the best interests of the company and, in the case of criminal proceedings, the person had no reasonable cause to believe that their conduct was unlawful. The decision of the directors as to whether the person acted honestly and in good faith and with a view to the best interests of the company and as to whether the person had no reasonable cause to believe that his conduct was unlawful and is, in the absence of fraud, sufficient for the purposes of the amended and restated memorandum and articles of association, unless a question of law is involved. The termination of any proceedings by any judgment, order, settlement, conviction or the entering of a nolle prosequi does not, by itself, create a presumption that the person did not act honestly and in good faith and with a view to the best interests of the company or that the person had reasonable cause to believe that his conduct was unlawful.

We have 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 will permit us to purchase and maintain insurance on behalf of any officer or director who at the request of the company is or was serving as a director or officer of, or in any other capacity is or was acting for, another company or a partnership, joint venture, trust or other enterprise, against any liability asserted against the person and incurred by the person in that capacity, whether or not the company has or would have had the power to indemnify the person against the liability as provided in our amended and restated memorandum and articles of association. We will 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.

These provisions may discourage shareholders from bringing a lawsuit against our directors for breach of their fiduciary duty or duty of care. These provisions also may have the effect of reducing the likelihood of derivative litigation against officers and directors, 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 theretofore unenforceable.
