Exhibit 4.5

CRANE HARBOR ACQUISITION CORP.

 DESCRIPTION OF SECURITIES

The following summary of the material terms of the securities of Crane Harbor Acquisition Corp., a Cayman Islands exempted company (“we,” “us,” “our” or the “Company”), is not intended to be a complete summary of the rights and preferences of such securities and is subject to and qualified by reference to our second amended and restated memorandum and articles of association and the share rights agreement, dated April 24, 2025, between the Company and Continental Stock Transfer & Trust Company (the “Share Rights Agreement”), in each case incorporated by reference as exhibits to the Company’s Annual Report on Form 10-K for the year ended December 31, 2025 (the “Report”), and applicable Cayman Islands law. We urge you to read our second amended and restated memorandum and articles of association and the Share Rights Agreement in their entirety for a complete description of the rights and preferences of our securities.

We are a Cayman Islands exempted company (company number 417084 ) and our affairs are governed by our second amended and restated memorandum and articles of association, the Companies Act and common law of the Cayman Islands. Pursuant to our second amended and restated memorandum and articles of association, we are authorized to issue 500,000,000 Class A ordinary shares, $0.0001 par value each, 50,000,000 Class B ordinary shares, $0.0001 par value and 5,000,000 undesignated preference shares, $0.0001 par value each.

Units

Each unit consists of one Class A ordinary share and one right to receive one tenth (1/10) of a Class A ordinary share upon the consummation of an initial business combination. 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, rights must be held in multiples of 10 in order to receive shares for all rights held upon closing of a business combination. The ordinary shares and rights comprising the units began separate trading on May 14, 2025.

Placement Units

The placement units (including the placement shares, the placement share rights and Class A ordinary shares issuable upon conversion of such rights) are not transferable or salable until 30 days after the completion of our initial business combination (subject to limited exceptions). Holders of our placement units are entitled to certain registration rights. If we do not consummate an initial business combination within the completion window, the proceeds from the sale of the private placement held in the trust account will be used to fund the redemption of our public shares (subject to the requirements of applicable law) and the placement units (and the underlying securities) will expire worthless. Further, if we seek shareholder approval, we will complete our initial business combination only if we obtain the approval of an ordinary resolution under Cayman Islands law, being the affirmative vote of a majority of the shareholders who, being present and entitled to vote at a general meeting of the company, vote at a general meeting of the company. In such case, our sponsor and each member of our management team have agreed to vote their founder shares, placement shares and any public shares purchased during or after the initial public offering in favor of our initial business combination. Otherwise, the placement units are identical to the units sold in the initial public offering.

In order to fund working capital deficiencies or finance transaction costs in connection with an intended initial business combination, our sponsor or one of its affiliates may loan us funds for working capital requirements and transaction costs. Up to $2,500,000 of such loans may be convertible into units at a price of $10.00 per unit at the option of the lender at the time of the business combination. The units would be identical to the placement units sold in the private placement.

Ordinary Shares

There are currently 29,973,333 ordinary shares issued and outstanding, including:

● 22,000,000 Class A ordinary shares underlying the units sold in the initial public offering;

● 640,000 Class A ordinary shares underlying the placement units sold in the private placement; and

● 7,333,333 Class B ordinary shares held by our initial holders.

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 and vote together as a single class, except as required by law or as provided below. Prior to our initial business combination, only holders of our founder shares will have the right to vote on the appointment of directors. Holders of our public shares will not be entitled to vote on the appointment of directors during such time. In addition, prior to our initial business combination, holders of a majority of our founder shares may remove a member of the board of directors for any reason. These provisions of our second amended and restated memorandum and articles of association may only be amended by a special resolution passed by at least 90% of our ordinary shares voting in a general meeting. Unless specified in the Companies Act, our second amended and restated memorandum and articles of association or applicable stock exchange rules, the affirmative vote of a majority of our ordinary shares that are voted is required to approve any such matter voted on by our shareholders (other than the appointment or removal of directors prior to our initial business combination), and, prior to our initial business combination, the affirmative vote of a majority of our founder shares is required to approve the appointment or removal of directors. Approval of certain actions will require a special resolution under Cayman Islands law and pursuant to our second amended and restated memorandum and articles of association; such actions include amending our second amended and restated memorandum and articles of association and approving a statutory merger or consolidation with another company. Directors are appointed for a term of three years. 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 appoint 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.

Because our second amended and restated memorandum and articles of association authorize the issuance of up to 500,000,000 Class A ordinary shares, if we were to enter into a business combination, we may (depending on the terms of such a business combination) be required to increase the number of ordinary shares which we are authorized to issue at the same time as our shareholders vote on the business combination to the extent we seek shareholder approval in connection with our initial business combination.

In accordance with Nasdaq corporate governance requirements, we are not required to hold an annual general meeting until no later than 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 general meetings or appoint directors. We may not hold an annual general meeting prior to the consummation of our initial business combination.

We will provide our Class A 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 outstanding public shares, subject to the limitations described herein. The amount in the trust account is initially approximately $10.00 per public share. The per-share amount we will distribute to investors who properly redeem their shares will not be reduced by the deferred underwriting commissions we will pay to the underwriter. The redemption rights will include the requirement that a beneficial owner must identify itself in order to validly redeem its shares. 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, placement shares and public shares in connection with the completion of our initial business combination or certain amendments to our second amended and restated memorandum and articles of association. Permitted transferees of our initial shareholders, directors or officers will be subject to the same obligations with respect to their founder shares. The non-managing sponsor investors are not required to (i) hold any units, Class A ordinary shares or public share rights they purchased in the initial public offering or thereafter for any amount of time, (ii) vote any Class A ordinary shares they may own at the applicable time in favor of our initial business combination or (iii) refrain from exercising their right to redeem their public shares at the time of our initial business combination. The non-managing sponsor investors will have the same rights to the funds held in the trust account with respect to the Class A ordinary shares underlying the units they purchased in the initial public offering as the rights afforded to our other public shareholders.

Unlike many blank check companies that hold shareholder votes and conduct proxy solicitations in conjunction with their initial business combinations and provide for related redemptions of public shares for cash upon completion of such initial business combinations even when a vote is not required by law, if a shareholder vote is not required by law and we do not decide to hold a shareholder vote for business or other legal reasons, we will, pursuant to our second amended and restated memorandum and articles of association, conduct the redemptions pursuant to the tender offer rules of the SEC, and file tender offer documents with the SEC prior to completing our initial business combination. Our second amended and restated memorandum and articles of association require these tender offer documents to contain substantially the same financial and other information about the initial business combination and the redemption rights as is required under the SEC’s proxy rules. If, however, shareholder approval of the transaction is required by law, or we decide to obtain shareholder approval for business or other legal reasons, we will, like many blank check companies, offer to redeem shares in conjunction with a proxy solicitation pursuant to the proxy rules and not pursuant to the tender offer rules. If we seek shareholder approval, we will complete our initial business combination only if we obtain the approval of an ordinary resolution under Cayman Islands law, being the affirmative vote of the holders of a majority of the issued ordinary shares who, being present and entitled to vote at a general meeting of the company, vote at a general meeting of the Company. However, the participation of our sponsor, officers, directors or their affiliates in privately-negotiated transactions, if any, could result in the approval of our initial business combination even if a majority of our public shareholders vote, or indicate their intention to vote, against such business combination. For purposes of seeking approval of the majority of our issued and outstanding ordinary shares, non-votes will have no effect on the approval of our initial business combination once a quorum is obtained. We intend to give not less than 10 days nor more than 60 days prior written notice of any such meeting, if required, at which a vote shall be taken to approve our initial business combination. These quorum and voting thresholds, and the voting agreements of our initial shareholders, may make it more likely that we will consummate our initial business combination.

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 the initial public offering, which we refer to as the “Excess Shares.” 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. And, 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.

If we seek shareholder approval in connection with our initial business combination, 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 founder shares and/or placement shares held by them, and any public shares purchased during or after the initial public offering, in favor of our initial business combination. Additionally, each public shareholder may elect to redeem their public shares irrespective of whether they vote for or against the proposed transaction or if they vote at all. The non-managing sponsor investors are not required to (i) hold any units, Class A ordinary shares or public share rights they purchased in the initial public offering or thereafter for any amount of time, (ii) vote any Class A ordinary shares they may own at the applicable time in favor of our initial business combination or (iii) refrain from exercising their right to redeem their public shares at the time of our initial business combination. The non-managing sponsor investors will have the same rights to the funds held in the trust account with respect to the Class A ordinary shares underlying the units they purchased in the initial public offering as the rights afforded to our other public shareholders.

Pursuant to our second amended and restated memorandum and articles of association, if we are unable to complete our initial business combination within the completion window, 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 (less taxes payable and up to $100,000 of interest to pay dissolution expenses) divided by the number of then 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 placement shares if we fail to complete our initial business combination within the completion window. However, if our sponsor, officers or directors acquire public shares after the initial public 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.

If we are unable to complete an initial business combination within the completion window, we may seek an amendment to our second amended and restated memorandum and articles of association to extend the period of time we have to complete an initial business combination beyond 24 months. Amending our second amended and restated memorandum and articles of association will require at least a special resolution of our shareholders as a matter of Cayman Islands law, meaning that such an amendment be approved by the affirmative vote of the holders of a majority of at least two-thirds (2/3) of the issued ordinary shares who, being present and entitled to vote at a general meeting, vote at a general meeting. If we seek shareholder approval to extend the initial 24-month period in which to complete an initial business combination to a later date, we will offer our public shareholders the right to have their public ordinary shares redeemed for a pro rata share of the aggregate amount then on deposit in the trust account.

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 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.

Founder Shares

The founder shares are designated as Class B ordinary shares and are identical to the ordinary shares included in the units sold in the initial public offering, and holders of founder shares have the same shareholder rights as public shareholders, except that (i) holders of the founder shares have the right to vote on the appointment of directors prior to our initial business combination, (ii) the founder shares are subject to certain transfer restrictions, as described in more detail below, and (iii) our sponsor, officers and directors have entered into a letter agreement with us, pursuant to which they have agreed to waive (A) their redemption rights with respect to their founder shares, placement shares and public shares held by them in connection with a shareholder vote to amend our second amended and restated memorandum and articles of association (1) to modify the substance or timing of our obligation to allow redemption in connection with our initial business combination or to redeem 100% of our public shares if we do not complete our initial business combination within 24 months from the closing of the initial public offering or (2) with respect to any other provision relating to shareholders’ rights or pre-initial business combination activity; and (C) their rights to liquidating distributions from the trust account with respect to any founder shares they hold if we fail to complete our initial business combination within 24 months from the closing of the initial public offering (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 the completion window); (iv) the founder shares will automatically convert into our Class A ordinary shares in connection with the consummation of our initial business combination, or at any time and from time to time at the option of the holder, on a one-for-one basis, subject to adjustment pursuant to certain anti-dilution rights, as described in more detail below; and (v) the founder shares are entitled to registration rights. If we submit our initial business combination to our public shareholders for a vote, our initial shareholders have agreed (and their permitted transferees will agree), pursuant to the terms of a letter agreement entered into with us, to vote their founder shares, placement shares and any public shares held by them purchased during or after the initial public offering in favor of our initial business combination. The non-managing sponsor investors are not required to (i) hold any units, Class A ordinary shares or public share rights they purchased in the initial public offering or thereafter for any amount of time, (ii) vote any Class A ordinary shares they may own at the applicable time in favor of our initial business combination or (iii) refrain from exercising their right to redeem their public shares at the time of our initial business combination. The non-managing sponsor investors will have the same rights to the funds held in the trust account with respect to the Class A ordinary shares underlying the units they purchased in the initial public offering as the rights afforded to our other public shareholders.

4

The Class B ordinary shares will automatically convert into Class A ordinary shares in connection with the consummation of our initial business combination, or at any time and from time to time at the option of the holders thereof, on a one-for-one basis, subject to adjustment for share sub-divisions, share capitalizations, reorganizations, recapitalizations and the like, and subject to further adjustment as provided herein and in our second amended and restated memorandum and articles of association. In the case that additional Class A ordinary shares, or equity-linked securities, are issued or deemed issued in excess of the amounts sold in the initial public offering and related to the closing of the business combination, the ratio at which Class B ordinary shares shall convert into Class A ordinary shares will be adjusted (unless the holders of a majority of the issued and outstanding Class B ordinary shares agree to waive such anti-dilution adjustment with respect to any such issuance or deemed issuance) so that the number of Class A ordinary shares issuable upon conversion of all Class B ordinary shares will equal, in the aggregate, 25% of the sum of all ordinary shares outstanding upon completion of the initial public offering plus all Class A ordinary shares and equity-linked securities issued or deemed issued in connection with the business combination (excluding any shares or equity-linked securities issued, or to be issued, to any seller in the initial business combination, and any private placement-equivalent shares and share rights underlying units issued to our sponsor or its affiliates upon conversion of loans made to us). The term “equity-linked securities” refers to any debt or equity securities that are convertible, exercisable or exchangeable for our Class A ordinary shares issued in a financing transaction in connection with our initial business combination, including but not limited to a private placement of equity or debt. Securities could be “deemed issued” for purposes of the conversion adjustment if such shares are issuable upon the conversion or exercise of convertible securities, share rights or similar securities.

With certain limited exceptions, the founder shares are not transferable, assignable or salable (except to our officers and directors and other persons or entities affiliated with our sponsor, each of whom will be subject to the same transfer restrictions) until the earlier of: (a) one year after the completion of our initial business combination; and (b) subsequent to our initial business combination (x) if the last reported sale price of our Class A ordinary shares equals or exceeds $12.00 per share (as adjusted for share sub-divisions, share dividends, rights issuances, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after our initial business combination or (y) the date on which we complete a liquidation, merger, share exchange, reorganization or other similar transaction that results in all of our public shareholders having the right to exchange their ordinary shares for cash, securities or other property.

Register of Members

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

● the names and addresses of the members, a statement of the shares held by each member, and of the amount paid or agreed to be considered as paid, on the shares of each member and the voting rights of the shares of each member;

● whether voting rights are attached to the share in issue;

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

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

5

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. 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 second amended and restated memorandum and articles of association 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.

Share Rights

Each holder of a share right will automatically receive one tenth (1/10) of one Class A ordinary share upon consummation of our initial business combination, even if the holder of a share right redeemed all Class A ordinary shares held by 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. In the event we will not be the surviving company upon completion of our initial business combination, each holder of a share right will be required to affirmatively convert its share rights in order to receive the one tenth (1/10) of one Class A ordinary share underlying each share right upon consummation of the business combination. Fractional shares will not be issued 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, share rights must be held in multiples of 10 in order to receive shares for all the share rights held 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 share rights will not receive any of such funds with respect to their share rights, nor will they receive any distribution from our assets held outside of the trust account with respect to such share rights, and the share rights will expire worthless. Further, there are no contractual penalties for failure to deliver securities to the holders of the share rights upon consummation of an initial business combination. Additionally, in no event will we be required to net cash settle the share rights. Accordingly, the share rights may expire worthless.

6

The share rights have been issued in registered form under the Share Rights Agreement. The Share Rights Agreement provides that the terms of the share rights may be amended without the consent of any holder for the purpose of (i) curing any ambiguity or to correct any defective provision or mistake, including to conform the provisions of the Share Rights Agreement to the description of the terms of the share rights and the Share Rights Agreement set forth in this prospectus or (ii) adding or changing any provisions with respect to matters or questions arising under the Share Rights Agreement as the parties to the Share Rights Agreement may deem necessary or desirable and that the parties deem to not adversely affect the rights of the registered holders of the share rights under the Share Rights Agreement, provided that the approval by the holders of at least 50% of the then-outstanding public share rights is required to make any change that adversely affects the rights of the registered holders of public share rights under the Share Rights Agreement. Accordingly, we may amend the terms of the public share rights in a manner adverse to a holder of publicshare rights if holders of at least 50% of the then-outstanding public share rights approve of such amendment. Although our ability to amend the terms of the public share rights with the consent of at least 50% of the then-outstanding public share rights is unlimited, examples of such amendments could be amendments to, among other things, convert the share rights into cash or another security or decrease the number of Class A ordinary shares exchangeable upon conversion of a share right. The share rights held by the underwriters may not be adversely affected without the written consent of the underwriters affected.

The Share Rights Agreement provides that, subject to applicable law, (i) any action, proceeding or claim against us arising out of or relating in any way to the Share 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 (ii) that we irrevocably submit to such jurisdiction, which jurisdiction shall be the exclusive forum for any such action, proceeding or claim. We will waive any objection to such exclusive jurisdiction and that such courts represent an inconvenient forum. With respect to any complaint asserting a cause of action arising under the Securities Act or the rules and regulations promulgated thereunder, we note, however, that there is uncertainty as to whether a court would enforce this provision 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.

Exclusive Forum

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 Share Rights Agreement 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. 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.
