Exhibit 4.5

DESCRIPTION OF REGISTRANT’S SECURITIES REGISTERED PURSUANT TO SECTION 12 OF
THE SECURITIES EXCHANGE ACT OF 1934

As of December 31, 2023, the end of the period covered by this Annual Report on Form 10-K, Trailblazer Merger Corp. I (the “Company,” “we,” “us,” or “our”) has three classes of securities registered under Section 12 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”): the Company’s Class A common stock, $0.0001 par value (“common stock”), , rights to receive one-tenth (1/10) of one Class A common stock and units comprised of one Class A common stock and one right to receive one-tenth (1/10) of one Class A common stock.

The following description of the Company’s share capital and provisions of the Company’s amended and restated certificate of incorporation and the are qualified in their entirety by reference to the and the.

General

Pursuant to our amended and restated certificate of incorporation, our authorized capital stock will consist of 100,000,000 shares of Class A common stock, $0.0001 par value, 5,000,000 shares of Class B common stock, $0.0001 par value, and 1,000,000 shares of undesignated preferred stock, $0.0001 par value. .

Units

Each unit has an offering price of $10.00 and consists of one share of Class A common stock and one right to receive one-tenth (1/10) of a share of Class A common stock.

Each right entitles the holder thereof to receive one-tenth (1/10) of one Class A common stock upon consummation of our initial business combination We will not issue fractional shares upon exchange of rights. A fractional interest in a share will either be rounded down to the nearest whole number of the number of shares to be issued to holder and, upon conversion, may pay in cash the fair value of fractions of a share as of the time when those entitled to receive such fractions are determined. Accordingly, unless you hold a multiple of ten units, your rights may expire worthless..

Common Stock

Prior to the consummation of our initial business combination, only holders of our Class B common stock will have the right to vote on the election of directors. Holders of the Class A common stock will not be entitled to vote on the election of directors during such time. These provisions of our amended and restated certificate of incorporation may only be amended if approved by at least 90% of our common stock voting at a stockholder meeting. With respect to other matters submitted to a vote of our stockholders, including any vote in connection with our initial business combination, except as required by applicable law or stock exchange rule, holders of our Class A common stock and holders of our Class B common stock will vote together as a single class, with each share entitling the holder to one vote. However, with respect to amending our charter to increase or decrease the aggregate number of authorized shares, holders of our Class A common stock and holders of our Class B common stock will vote as a separate class. Unless specified in our amended and restated certificate of incorporation or bylaws, or as required by applicable provisions of the Delaware General Corporation Law (the “DGCL”) or applicable stock exchange rules, the affirmative vote of a majority of our shares of common stock that are voted is required to approve any such matter voted on by our stockholders. Our board of directors will be divided into three classes, each of which will generally serve for a term of only one class of directors being elected in each year. There is no cumulative voting with respect to the election of directors, with the result that the holders of more than 50% of the shares voted for the election of directors can elect all of the directors. Our stockholders are entitled to receive ratable dividends when, as and if declared by the board of directors out of funds legally available therefor.

Because our amended and restated certificate of incorporation will authorize the issuance of up to 100,000,000 shares of Class A common stock, if we were to enter into an initial business combination, we may (depending on the terms of such an initial business combination) be required to increase the number of shares of Class A common stock which we are authorized to issue at the same time as our stockholders vote on the initial business combination to the extent we seek stockholder approval in connection with our initial business combination.

In accordance with Nasdaq corporate governance requirements, we are not required to hold an annual meeting until no later than one year after our first fiscal year end following our listing on Nasdaq. Under Section 211(b) of the DGCL, we are, however, required to hold an annual meeting of stockholders for the purposes of electing directors in accordance with our bylaws, unless such election is made by written consent in lieu of such a meeting. We may not hold an annual meeting of stockholders to elect new directors prior to the consummation of our initial business combination, and thus we may not be in compliance with Section 211(b) of the DGCL, which requires an annual meeting. Therefore, if our stockholders want us to hold an annual meeting prior to the consummation of our initial business combination, they may attempt to force us to hold one by submitting an application to the Delaware Court of Chancery in accordance with Section 211(c) of the DGCL.

We will provide our stockholders 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 earned on the funds held in the trust account and not previously released to us to pay our taxes, divided by the number of then outstanding public share. The amount in the trust account is initially anticipated to be approximately $10.20 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 underwriters. 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 any founder shares, any placement shares and any public shares held by them in connection with (i) the completion of our initial business combination or (ii) a stockholder vote to approve an amendment to our amended and restated certificate of incorporation (A) 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 twelve (12) months from the closing of the offering (or up to 18 months, if we extend the time to complete an initial business combination as described in the prospectus) or (B) with respect to any other provision relating to stockholders’ rights or pre-initial business combination activity.

In the event of a liquidation, dissolution or winding up of the company after an initial business combination, our stockholders 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 stock, if any, having preference over the common stock. Our stockholders have no preemptive or other subscription rights. There are no sinking fund provisions applicable to the common stock, except that we will provide our stockholders 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, upon the completion of our initial business combination.

Founder Shares

The founder shares are identical to the shares of Class A common stock included in the units being sold in the offering, and holders of founder shares have the same stockholder rights as public stockholders, except that (i) the founder shares are subject to certain transfer restrictions, as described in more detail below, (ii) our sponsor, officers and directors have entered into a letter agreement with us, pursuant to which they have agreed (A) to waive their redemption rights with respect to any founder shares, any placement shares and any public shares held by them in connection with the completion of our initial business combination, (B) to waive their redemption rights with respect to their founder shares, placement shares and any public shares in connection with a stockholder vote to approve an amendment to our amended and restated certificate of incorporation (x) 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 twelve (12) months from the closing of the offering (or up to 18 months, if we extend the time to complete a business combination as described in the prospectus), or (y) with respect to any other provision relating to stockholders’ rights or pre-initial business combination activity and (C) to waive their rights to liquidating distributions from the trust account with respect to any founder shares and placement shares held by them if we fail to complete our initial business combination within twelve (12) months from the closing of the offering (or up to 18 months, if we extend the time to complete a business combination as described in the prospectus), 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, and (iii) are entitled to registration rights. If we submit our initial business combination to our public stockholders for a vote, our sponsor, officers and directors have agreed pursuant to the letter agreement to vote any founder shares held by them and any public shares purchased during or after the offering (including in open market and privately negotiated transactions) in favor of our initial business combination.

2

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 or (B) subsequent to our initial business combination, (x) if the last sale price of our Class A common stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least six months after our initial business combination, or (y) the date on which we complete a liquidation, merger, capital stock exchange, reorganization or other similar transaction that results in all of our stockholders having the right to exchange their shares of common stock for cash, securities or other property.

Preferred Stock

Our amended and restated certificate of incorporation provides that shares of preferred stock 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 stockholder approval, issue preferred stock with voting and other rights that could adversely affect the voting power and other rights of the holders of the common stock and could have anti-takeover effects. The ability of our board of directors to issue preferred stock without stockholder 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 preferred stock outstanding at the date hereof. Although we do not currently intend to issue any shares of preferred stock, we cannot assure you that we will not do so in the future. No shares of preferred stock are being issued or registered in the offering.

Placement Units

The placement units (including the placement shares and the placement rights included in the placement units, and the shares of common stock underlying the placement rights) will not be transferable, assignable or saleable until 30 days after the completion of our initial business combination (except that, among other limited exceptions as described under the section of the prospectus entitled “Principal Stockholders — Restrictions on Transfers of Founder Shares and Placement Units” transfers, assignments and sales may be made to our officers and directors and other persons or entities affiliated with or related to our sponsor, each of whom will be subject to the same transfer restrictions) so long as they are held by our sponsor or its permitted transferees. Otherwise, the placement units have terms and provisions that are identical to those of the units being sold in the offering, including as to exercise price, exercisability and exercise period. Each of the units that may be issued upon conversion of working capital loans shall be identical to the placement units.

In order to fund working capital deficiencies or finance transaction costs in connection with an intended initial business combination, our sponsor or an affiliate of our sponsor or certain of our officers and directors may, but are not obligated to, loan us funds as may be required. Up to $1,500,000 of such loans may be convertible into units, at a price of $10.00 per unit at the option of the lender. The units would be identical to the placement units.

Rights included as part of units

Each holder of a right will receive one-tenth (1/10) of one share of Class A common stock upon consummation of our initial business combination, even if the holder of such right redeemed all shares of common stock held by it in connection with the initial business combination. No additional consideration will be required to be paid by a holder of rights in order to receive its additional 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 the offering. 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 Class A common stock will receive in the transaction on an as-converted into common stock basis, and each holder of a right will be required to affirmatively convert his, her or its rights in order to receive the 1/10 of a 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 its election to convert the rights into underlying shares as well as to return the original rights certificates to us.

3

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 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 rights the number of full shares of Class A common stock to which 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 common stock 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, you might not receive the Class A common stock underlying the rights.

The shares of Class A common stock issuable upon conversion of the rights will be freely tradable (except to the extent held by affiliates of ours). 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.

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 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 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.

Dividends

We have not paid any cash dividends on our common stock to date and do not intend to pay cash dividends prior to the completion of an initial 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 conditions subsequent to completion of an initial business combination. The payment of any cash dividends subsequent to an initial business combination will be within the discretion of our board of directors at such time. 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 common stock and rights agent for our rights is Continental Stock Transfer & Trust Company.
