Exhibit 4.5

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

As of December 31, 2021, byNordic Acquisition Corporation (“we,” “our,” “us” or the “Company”) did not have any classes of securities registered under Section 12 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Upon the closing the Company’s initial public offering on February 11, 2022, the Company had the following three classes of securities registered under Section 12 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”): (i) its Units, consisting of one share of Class A common stock (as defined below) and one-half of one redeemable warrant (as defined below), with each whole warrant entitling the holder thereof to purchase one share of Class A common stock (the “Units”), (ii) its Class A common stock, $0.0001 par value per share (“Class A common stock”), and (iii) its public warrants, with each whole warrant exercisable for one share of Class A common stock for $11.50 per share (the “warrants”).

Pursuant to our amended and restated certificate of incorporation, our authorized capital stock consists of 110,000,000 shares of common stock, including 100,000,000 shares of Class A common stock, $0.0001 par value and 10,000,000 shares of Class B common stock, $0.0001 par value, and 1,000,000 shares of undesignated preferred stock, $0.0001 par value. The following description summarizes the material terms of our capital stock and does not purport to be complete. It is subject to, and qualified in its entirety by reference to, our amended and restated certificate of incorporation, our bylaws and our warrant agreement, each of which is incorporated by reference as an exhibit to our Annual Report on Form 10-K for the year ended December 31, 2021 (the “Report”) of which this Exhibit 4.5 is a part.

Defined terms used herein but not otherwise defined shall have the meaning ascribed to such terms in the Report.

Units

Each Unit consists of one whole share of Class A common stock and one-half of one redeemable warrant. Each whole warrant entitles the holder thereof to purchase one share of our Class A common stock at a price of $11.50 per share. Pursuant to the warrant agreement, a warrantholder may exercise its warrants only for a whole number of shares of Class A common stock.

Common Stock

Common stockholders of record are entitled to one vote for each share held on all matters to be voted on by stockholders. Holders of the Class A common stock and holders of the Class B common stock will vote together as a single class on all matters submitted to a vote of our stockholders, except as required by law. There is no cumulative voting with respect to the election of 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.

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 issued and outstanding public shares, subject to the limitations described herein. Our sponsor, byNordic Holdings, byNordic Holdings II and our executive officers and directors (referred to herein as the insiders) 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, the private shares and any public shares they may acquire during or after our initial public offering in connection with the completion of our initial business combination or otherwise. The anchor investors have agreed in the letter agreements entered into with us and our sponsor and byNordic Holdings for the purchase of their founder shares that they have no rights to amounts on deposit in the trust account with respect to the founder shares purchased by them. In addition, the insiders and the anchor investors have agreed to waive their rights to liquidating distributions from the trust account with respect to any founder shares held by them if we fail to complete our initial business combination within the prescribed time frame. However, if they acquire public shares in or after our 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 frame.

If we seek stockholder 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 amended and restated certificate of incorporation provides that a public stockholder, together with any affiliate of such stockholder or any other person with whom such stockholder 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 shares of common stock sold in our initial public offering, which we refer to as the Excess Shares. However, we would not be restricting our stockholders’ ability to vote all of their shares (including Excess Shares) for or against our initial business combination. Our stockholders’ inability to redeem the Excess Shares will reduce their influence over our ability to complete our initial business combination, and such stockholders could suffer a material loss in their investment if they sell such Excess Shares on the open market. Additionally, such stockholders will not receive redemption distributions with respect to the Excess Shares if we complete the initial business combination. And, as a result, such stockholders will continue to hold that number of shares exceeding 15% and, in order to dispose of such shares would be required to sell their stock in open market transactions, potentially at a loss.

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, subject to the limitations described in the Report.

Redeemable Warrants

Each whole warrant entitles the registered holder to purchase one whole share of our Class A common stock at a price of $11.50 per share, subject to adjustment as discussed below, at any time commencing on the later of February 11, 2023 or 30 days after the completion of our initial business combination. Pursuant to the warrant agreement, a warrantholder may exercise its warrants only for a whole number of shares of Class A common stock.

The warrants will expire five years after the completion of our initial business combination, at 5:00 p.m., New York City time, or earlier upon redemption or liquidation.

We will not be obligated to deliver any shares of Class A common stock pursuant to the exercise of a warrant and will have no obligation to settle such warrant exercise unless a registration statement under the Securities Act with respect to the shares of Class A common stock underlying the warrants is then effective and a prospectus relating thereto is current, subject to our satisfying our obligations described below with respect to registration. No warrant will be exercisable and we will not be obligated to issue shares of Class A common stock upon exercise of a warrant unless Class A common stock issuable upon such warrant exercise has been registered, qualified or deemed to be exempt under the securities laws of the state of residence of the registered holder of the warrants. In the event that the conditions in the two immediately preceding sentences are not satisfied with respect to a warrant, the holder of such warrant will not be entitled to exercise such warrant and such warrant may have no value and expire worthless. In no event will we be required to net cash settle any warrant. In the event that a registration statement is not effective for the exercised warrants, the purchaser of a Unit containing such warrant will have paid the full purchase price for the Unit solely for the share of Class A common stock underlying such Unit.

We have agreed that as soon as practicable, but in no event later than 15 business days after the closing of our initial business combination, we will use our best efforts to file with the SEC a registration statement covering the shares of Class A common stock issuable upon exercise of the warrants, to cause such registration statement to become effective and to maintain a current prospectus relating to those shares of Class A common stock until the warrants expire or are redeemed, as specified in the warrant agreement. Notwithstanding the foregoing, if a registration statement covering the Class A common stock issuable upon exercise of the warrants is not effective by the 60^th business day following the consummation of our initial business combination, warrant holders may, until such time as there is an effective registration statement and during any period when we shall have failed to maintain an effective registration statement, exercise warrants on a cashless basis pursuant to the exemption provided by Section 3(a)(9) of the Securities Act of 1933, as amended, or the Securities Act, provided that such exemption is available. If that exemption, or another exemption, is not available, holders will not be able to exercise their warrants on a cashless basis.

Once the warrants become exercisable, we may call the warrants for redemption:

● in whole and not in part;

● at a price of $0.01 per warrant;

● upon not less than 30 days’ prior written notice of redemption (the “30-day redemption period”) to each warrantholder; and

2

● if, and only if, the reported last sale price of the Class A common stock equals or exceeds $18.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like and for certain issuances of Class A common stock and equity-linked securities as described above) for any 20 trading days within a 30-trading day period commencing once the warrants become exercisable and ending three business days before we send the notice of redemption to the warrantholders.

If and when the warrants become redeemable by us, we may not exercise our redemption right if the issuance of shares of common stock upon exercise of the warrants is not exempt from registration or qualification under applicable state blue sky laws or we are unable to effect such registration or qualification. If necessary, we will use our best efforts to register or qualify such shares of common stock under the blue sky laws of the state of residence in those states in which the warrants were offered by us in our initial public offering.

If we call the warrants for redemption as described above, our management will have the option to require any holder that wishes to exercise its warrant to do so on a “cashless basis.” In determining whether to require all holders to exercise their warrants on a “cashless basis,” our management will consider, among other factors, our cash position, the number of warrants that are outstanding and the dilutive effect on our stockholders of issuing the maximum number of shares of Class A common stock issuable upon the exercise of our warrants. If our management takes advantage of this option, all holders of warrants would pay the exercise price by surrendering their warrants for that number of shares of Class A common stock equal to the quotient obtained by dividing (x) the product of the number of shares of Class A common stock underlying the warrants, multiplied by the difference between the exercise price of the warrants and the “fair market value” (defined below) by (y) the fair market value. The “fair market value” shall mean the average reported last sale price of the Class A common stock for the 10 trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of warrants. If our management takes advantage of this option, the notice of redemption will contain the information necessary to calculate the number of shares of Class A common stock to be received upon exercise of the warrants, including the “fair market value” in such case. Requiring a cashless exercise in this manner will reduce the number of shares to be issued and thereby lessen the dilutive effect of a warrant redemption. We believe this feature is an attractive option to us if we do not need the cash from the exercise of the warrants after our initial business combination.

A holder of a warrant may notify us in writing in the event it elects to be subject to a requirement that such holder will not have the right to exercise such warrant, to the extent that after giving effect to such exercise, such person (together with such person’s affiliates), to the warrant agent’s actual knowledge, would beneficially own in excess of 4.9% or 9.8% (or such other amount as a holder may specify) of the shares of Class A common stock issued and outstanding immediately after giving effect to such exercise.

The warrants have certain anti-dilution and adjustments rights upon certain events.

The warrants were issued in registered form under a warrant agreement between Continental, as warrant agent, and us. You should review a copy of the warrant agreement, which was filed with the Registration Statement, for a complete description of the terms and conditions applicable to the warrants. The warrant agreement provides that the terms of the warrants may be amended without the consent of any holder to cure any ambiguity or correct any defective provision, but requires the approval by the holders of at least a majority of the then outstanding warrants to make any change that adversely affects the interests of the registered holders of warrants.

The warrants may be exercised upon surrender of the warrant certificate on or prior to the expiration date at the offices of the warrant agent, with the exercise form on the reverse side of the warrant certificate completed and executed as indicated, accompanied by full payment of the exercise price (or on a cashless basis, if applicable), by certified or official bank check payable to us, for the number of warrants being exercised. The warrantholders do not have the rights or privileges of holders of Class A common stock and any voting rights until they exercise their warrants and receive shares of Class A common stock. After the issuance of shares of Class A common stock upon exercise of the warrants, each holder will be entitled to one (1) vote for each share held of record on all matters to be voted on by stockholders.

In addition, if (x) we issue additional shares of Class A common stock or equity-linked securities for capital raising purposes in connection with the closing of our initial business combination at a Newly Issued Price of less than $9.20 per share of Class A common stock (with such issue price or effective issue price to be determined in good faith by our board of directors and, in the case of any such issuance to our sponsor or its affiliates, without taking into account any founder shares held by our sponsor or such affiliates, as applicable, prior to such issuance), (y) the aggregate gross proceeds from such issuances represent more than 60% of the total equity proceeds, and interest thereon, available for the funding of our initial business combination on the date of the consummation of our initial business combination (net of redemptions), and (z) the Market Value is below $9.20 per share, the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the higher of the Market Value and the Newly Issued Price, and the $18.00 per share redemption trigger price described above will be adjusted (to the nearest cent) to be equal to 180% of the higher of the Market Value and the Newly Issued Price. No fractional shares will be issued upon exercise of the warrants. If, upon exercise of the warrants, a holder would be entitled to receive a fractional interest in a share, we will, upon exercise, round down to the nearest whole number of shares of Class A common stock to be issued to the warrantholder.
