Description of the Company's securities

Exhibit 4.5

ARCHIMEDES TECH SPAC PARTNERS II CO.

DESCRIPTION OF SECURITIES

The following summary of the material terms of the securities of Archimedes Tech SPAC Partners II Co. (“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 amended and restated memorandum and articles of association incorporated by reference as an exhibit to the Company’s Annual Report on Form 10-K for the year ended December 31, 2024 (the “Report”) and applicable Cayman Islands law.

Pursuant to our amended and restated memorandum and articles of association, our authorised share capital consists of 400,000,000 ordinary shares, $0.0001 par value each, and 1,000,000 preference shares, $0.0001 par value each. The following description summarizes the material terms of our share capital.

UNITS

Each unit consists of one ordinary share and one-half of one redeemable warrant. Each whole warrant entitles the holder thereof to purchase one ordinary share at a price of $11.50 per share, subject to adjustment. Pursuant to the warrant agreement, a warrant holder may exercise its warrants only for a whole number of ordinary shares. This means that only a whole warrant may be exercised at any given time by a warrant holder. No fractional warrants will be issued upon separation of the units and only whole warrants will trade.

The ordinary shares and warrants constituting the units will begin separate trading on the 52^nd day following the date of the prospectus of the Company’s initial public offering (or, if such date is not a business day, the following business day) unless BTIG, LLC informs us of its decision to allow earlier separate trading, subject to our having filed the Current Report on Form 8-K described below and having issued a press release announcing when such separate trading will begin. Once the ordinary shares and warrants commence separate trading, holders will have the option to continue to hold units or separate their units into the component securities. Holders will need to have their brokers contact our transfer agent in order to separate the units into ordinary shares and warrants. Additionally, the units will automatically separate into their component parts and will not be traded after completion of our initial business combination. No fractional warrants will be issued upon separation of the units and only whole warrants will trade.

ORDINARY SHARES

As of the date of the Report, 29,590,000 ordinary shares are issued and outstanding.

Holders of record of ordinary shares are entitled to one vote for each share held on all matters to be voted on by shareholders and vote together as a single class, except as required by law.

Unless specified in our amended and restated memorandum and articles of association, or as required by applicable law or stock exchange rules, the affirmative vote of holders of a majority of the outstanding ordinary shares that are voted is required to approve any such matter voted on by our shareholders. Approval of other certain actions will require a special resolution under Cayman Islands law and/or pursuant to our amended and restated memorandum and articles of association; which requires the affirmative vote of shareholders holding at least two-thirds of our ordinary shares who attend and vote at a general meeting of the company, such actions include amending our amended and restated memorandum and articles of association and approving a statutory merger or consolidation with another company. Our board of directors will be divided into three classes, each of which will generally serve for a term of three years with only one class of directors being elected in each year. There is no cumulative voting with respect to the appointment of directors. 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 amended and restated memorandum and articles of association will authorize the issuance of up to 400,000,000 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 one year after our first fiscal year end following our listing on Nasdaq.

Pursuant to our amended and restated memorandum and articles of association, if we have not completed our initial business combination within the completion window, we will (1) cease all operations except for the purpose of winding up, (2) as promptly as reasonably possible but not more than ten business days thereafter, 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 (net of funds withdrawn to pay our taxes and up to $100,000 of interest to pay dissolution expenses), divided by the number of then issued and outstanding public shares, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidating distributions, if any), and (3) 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 laws to provide for claims of creditors and the requirements of other applicable law. Our initial shareholders have entered into a letter agreement with us, pursuant to which they have agreed to waive their rights to liquidating distributions from the trust account with respect to their founder shares and private shares if we fail to complete our initial business combination within the completion window. However, if our initial shareholders or any of our directors, officers or affiliates acquire public shares, they will be entitled to liquidating distributions from the trust account with respect to such public shares if we fail to complete our initial business combination within the prescribed time period.

In the event of a liquidation, dissolution or winding up of the company after a business combination, our shareholders at such time will be 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 (net of funds withdrawn to pay our taxes and up to $100,000 of interest to pay dissolution expenses), upon the completion of our initial business combination, subject to the limitations described herein.

FOUNDER SHARES

The founder shares are identical to the ordinary shares included in the units sold in our initial public offering, and holders of founder shares have the same shareholder rights as public shareholders, except that: (1) the founder shares are subject to certain transfer restrictions contained in a letter agreement that our initial shareholders, directors and officers have entered into with us, as described in more detail below; (2) pursuant to such letter agreement, our initial shareholders, directors and officers have agreed to waive: (i) their redemption rights with respect to any shares held by them in connection with the completion of our initial business combination; (ii) their redemption rights with respect to any shares held by them in connection with a shareholder vote to amend our amended and restated memorandum and articles of association (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 the completion window or (B) with respect to any other material provisions relating to shareholders’ rights or pre-initial business combination activity; and (iii) their rights to liquidating distributions from the trust account with respect to any founder shares and private shares they hold if we fail to complete our initial business combination within the completion window (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); and (3) 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, directors and officers have agreed (and their permitted transferees will agree), pursuant to the terms of a letter agreement entered into with us, to vote any shares held by them in favor of our initial business combination.

Pursuant to a letter agreement that our initial shareholders, directors and officers have entered into with us, with certain limited exceptions, the founder shares are not transferable, assignable or salable (except to our directors and officers and other persons or entities affiliated with our initial shareholders, each of whom will be subject to the same transfer restrictions) until the earlier of: (i) six months after the completion of our initial business combination; and (ii) subsequent to our initial business combination, 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. Notwithstanding the foregoing, the founder shares will be released from the lock-up if (1) the last reported sale price of our ordinary shares equals or exceeds $12.00 per share (as adjusted for share splits, share capitalizations, reorganizations, recapitalizations and other similar transactions) for any 20 trading days within any 30-trading day period after our initial business combination or (2) if we complete a transaction after our initial business combination which results in all of our shareholders having the right to exchange their shares for cash, securities or other property.

Register of Members

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

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 will 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. The shareholders recorded in the register of members will 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 authorize 1,000,000 preference shares and provide that preference shares may be issued from time to time in one or more series. Our board of directors are 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 is 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 issued and outstanding at the date hereof. As of the date of the Report, no preference shares are issued and outstanding.

WARRANTS

Public Shareholders’ Warrants

Each whole warrant entitles the registered holder to purchase one ordinary share at a price of $11.50 per share, subject to adjustment, at any time commencing on the later of 12 months from the closing of our initial public offering or 30 days after the completion of our initial business combination. Pursuant to the warrant agreement, a warrant holder may exercise its warrants only for a whole number of ordinary shares. This means that only a whole warrant may be exercised at any given time by a warrant holder. No fractional warrants will be issued upon separation of the units and only whole warrants will trade. 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 ordinary shares 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 ordinary shares 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 for cash or on a cashless basis, and we will not be obligated to issue any shares to holders seeking to exercise their warrants, unless the issuance of the shares upon such exercise is registered or qualified under the securities laws of the state of the exercising holder, or an exemption is available. 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 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 ordinary share underlying such unit.

We agree that as soon as practicable, but in no event later than twenty (20) 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 ordinary shares issuable upon exercise of the warrants. We will use our best efforts to cause such registration statement to become effective within 60 business days after the closing of our initial business combination and to maintain a current prospectus relating to those ordinary shares until the warrants expire or are redeemed, as specified in the warrant agreement. If a registration statement covering the ordinary shares issuable upon exercise of the warrants is not effective by the 60^th business day after the closing of our initial business combination or any time thereafter, warrant holders may, until such time as there is an effective registration statement and during any period when we will have failed to maintain an effective registration statement, exercise warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act or another exemption. In the case of a cashless exercise, each holder would pay the exercise price by surrendering the warrants for that number of ordinary shares equal to the lesser of the quotient obtained by dividing (x) the product of the number of ordinary shares underlying the warrants multiplied by the difference between the exercise price of the warrants and the “fair market value” (as defined below) by (y) the fair market value. The “fair market value” as used in this paragraph shall mean the average reported closing price for the five trading days ending on the third trading day prior to the date on which the notice of redemption is sent to holders of the warrants.

The private warrants, as well as any warrants underlying additional units we issue to our sponsor or an affiliate of our sponsor or certain of our officers and directors in payment of working capital loans made to us, will be identical to the warrants underlying the units being offered in our initial public offering. For so long as they are held by BTIG or its affiliates or associated persons, the private warrants will not be exercisable more than five years from the commencement of sales in our initial public offering in accordance with FINRA rules.

Redemption of Warrants

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

If and when the warrants become redeemable by us, we may not exercise our redemption right if the issuance of shares 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. We will use our best efforts to register or qualify such shares 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.

We have established the last of the redemption criterion discussed above to prevent a redemption call unless there is at the time of the call a significant premium to the warrant exercise price. If the foregoing conditions are satisfied and we issue a notice of redemption of the warrants, each warrant holder will be entitled to exercise his, her or its warrant prior to the scheduled redemption date. However, the price of the ordinary shares may fall below the $18.00 redemption trigger price as well as the $11.50 warrant exercise price after the redemption notice is issued.

If we call the warrants for redemption as described above, our management will have the option to require any holder that wishes to exercise his, her or 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 issued and outstanding and the dilutive effect on our shareholders of issuing the maximum number of ordinary shares 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 ordinary shares equal to the quotient obtained by dividing (x) the product of the number of ordinary shares 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 closing price of the ordinary shares for the five 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 ordinary shares 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) or any “group” of which the holder or its affiliates is a member would beneficially own in excess of 4.9% or 9.8% (or such other amount as the holder may specify) of the ordinary shares issued and outstanding immediately after giving effect to such exercise.

Anti-Dilution Adjustments

If the number of issued and outstanding ordinary shares is increased by a capitalization payable in ordinary shares, or by a sub-division of ordinary shares or other similar event, then, on the effective date of such capitalization, sub-division or similar event, the number of ordinary shares issuable on exercise of each warrant will be increased in proportion to such increase in the issued and outstanding ordinary shares. A rights offering to holders of ordinary shares entitling holders to purchase ordinary shares at a price less than the fair market value will be deemed a capitalization of a number of ordinary shares equal to the product of (i) the number of ordinary shares actually sold in such rights offering (or issuable under any other equity securities sold in such rights offering that are convertible into or exercisable for ordinary shares) multiplied by (ii) one (1) minus the quotient of (x) the price per ordinary share paid in such rights offering divided by (y) the fair market value. For these purposes (i) if the rights offering is for securities convertible into or exercisable for ordinary shares, in determining the price payable for ordinary shares, there will be taken into account any consideration received for such rights, as well as any additional amount payable upon exercise or conversion and (ii) fair market value means the volume weighted average price of ordinary shares as reported during the ten (10) trading day period ending on the trading day prior to the first date on which the ordinary shares trade on the applicable exchange or in the applicable market, regular way, without the right to receive such rights.

In addition, if we, at any time while the warrants are issued and outstanding and unexpired, pay a dividend or make a distribution in cash, securities or other assets to the holders of ordinary shares on account of such ordinary shares (or other ordinary shares into which the warrants are convertible), other than (a) as described above, (b) certain ordinary cash dividends of not greater than $0.10 per share per annum (subject to adjustment), (c) to satisfy the redemption rights of the holders of ordinary shares in connection with a proposed initial business combination, (d) to satisfy the redemption rights of the holders of ordinary shares in connection with a shareholder vote to amend our amended and restated memorandum and articles of association 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 ordinary shares if we do not complete our initial business combination within the completion window, or (e) in connection with the redemption of our public shares upon our failure to complete our initial business combination, then the warrant exercise price will be decreased, effective immediately after the effective date of such event, by the amount of cash and/or the fair market value of any securities or other assets paid on each ordinary share in respect of such event.

If the number of issued and outstanding ordinary shares is decreased by a consolidation, combination or reclassification of ordinary shares or other similar event, then, on the effective date of such consolidation, combination, reclassification or similar event, the number of ordinary shares issuable on exercise of each warrant will be decreased in proportion to such decrease in issued and outstanding ordinary shares.

Whenever the number of ordinary shares purchasable upon the exercise of the warrants is adjusted, as described above, the warrant exercise price will be adjusted by multiplying the warrant exercise price immediately prior to such adjustment by a fraction (x) the numerator of which will be the number of ordinary shares purchasable upon the exercise of the warrants immediately prior to such adjustment, and (y) the denominator of which will be the number of ordinary shares so purchasable immediately thereafter.

In case of any reclassification or reorganization of the issued and outstanding ordinary shares (other than those described above or that solely affects the par value of such ordinary shares), or in the case of any merger or consolidation of us with or into another entity in which any “person” or “group” (as such terms are used in Section 13(d) and 14(d) of the Exchange Act) acquires more than 50% of the voting power of the securities, or in the case of any sale or conveyance to another corporation or entity of the assets or other property of us as an entirety or substantially as an entirety, the holders of the warrants will thereafter have the right to purchase and receive, upon the basis and upon the terms and conditions specified in the warrants and in lieu of our ordinary shares immediately theretofore purchasable and receivable upon the exercise of the rights represented thereby, the kind and amount of shares or other securities or property (including cash) receivable upon such reclassification, reorganization, merger or consolidation, or upon a dissolution following any such sale or transfer, that the holder of the warrants would have received if such holder had exercised their warrants immediately prior to such event.

The warrants will be issued in registered form under a warrant agreement between Odyssey Transfer and Trust Company, as warrant agent, and us. 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, or correct any mistake, including to conform the provisions of the warrant agreement to the description of the terms of the warrants and the warrant agreement set forth in the prospectus of the Company’s initial public offering, but with respect to any change that adversely affects the interests of the registered holders of public warrants, requires the approval by the holders of at least (i) a majority of the then issued and outstanding public warrants if such modification or amendment is being undertaken prior to, or in connection with, the consummation of a business combination or (ii) a majority of the then outstanding warrants (including the private warrants) if such modification or amendment is being undertaken after the consummation of a business combination.

In addition, if (x) we issue additional ordinary shares 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 ordinary share (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, then 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. 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 good certified check payable to the order of the warrant agent or by wire transfer, for the number of warrants being exercised. The warrant holders do not have the rights or privileges of holders of ordinary shares and any voting rights until they exercise their warrants and receive ordinary shares. After the issuance of ordinary shares upon exercise of the warrants, each holder will be entitled to one vote for each share held of record on all matters to be voted on by shareholders.

Warrants may be exercised only for a whole number of ordinary shares. 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 the number of ordinary shares to be issued to the warrant holder. Unless, if by reason of any adjustment described above, the holder of warrants would be entitled to receive a fractional interest in a share, we will, upon exercise, round up to the nearest whole the number of ordinary shares to be issued to the warrant holder.

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 warrant 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. Notwithstanding the foregoing, this provision does not apply to suits brought to enforce any liability or duty created by the Securities Act or the Exchange Act or any other claim for which the federal district courts of the United States of America are the sole and exclusive forum. We note that there is uncertainty as to whether a court would enforce such provision, and that investors cannot waive compliance with the federal securities laws and the rules and regulations thereunder. The Securities Act creates concurrent jurisdiction for federal and state 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. The payment of cash dividends in the future will be, subject to applicable law, 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 cash dividends subsequent to our initial business combination will be within the discretion of our board of directors at such time. In addition, our board of directors is not currently contemplating and does not anticipate declaring any share dividends in the foreseeable future. Further, if we incur any indebtedness in connection with our initial business combination, our ability to declare dividends may be limited by restrictive covenants we may agree to in connection therewith.

OUR TRANSFER AGENT AND WARRANT AGENT

The transfer agent for our ordinary shares and warrant agent for our warrants is Odyssey Transfer and Trust Company. We have agreed to indemnify Odyssey Transfer and Trust Company in its roles as transfer agent and warrant agent, its agents and each of its shareholders, directors, officers and employees against all liabilities, including judgments, costs and reasonable counsel fees that may arise out of acts performed or omitted for its activities in that capacity, except for any liability due to any gross negligence, willful misconduct or bad faith of the indemnified person or entity.

CERTAIN DIFFERENCES IN CORPORATE LAW

Cayman Islands companies are governed by the Companies Act. The Companies Act is modeled on English Law but does not follow recent English Law statutory enactments, and differs from laws applicable to United States corporations and their shareholders. Set forth below is a summary of the material differences between the provisions of the Companies Act applicable to us and the laws applicable to companies incorporated in the United States and their shareholders.

Mergers and Similar Arrangements.    In certain circumstances, the Companies Act allows for mergers or consolidations between two Cayman Islands companies, or between a Cayman Islands exempted company and a company incorporated in another jurisdiction (provided that is facilitated by the laws of that other jurisdiction).

Where the merger or consolidation is between two Cayman Islands companies, the directors of each company must approve a written plan of merger or consolidation containing certain prescribed information. That plan or merger or consolidation must then be authorized by either (a) a special resolution (usually a majority of two-thirds of the voting shares voted at a general meeting) of the shareholders of each company; or (b) such other authorization, if any, as may be specified in such constituent company’s articles of association. No shareholder resolution is required for a merger between a parent company (i.e., a company that owns at least 90% of the issued shares of each class in a subsidiary company) and its subsidiary company if a copy of the plan of merger is provided to every member of each subsidiary company to be merged unless that such member agrees otherwise. The consent of each holder of a fixed or floating security interest of a constituent company must be obtained, unless the court waives such requirement. The directors of each company are required to provide a declaration of the assets and liabilities of the company made up to the latest practicable date before the making of the declaration, and are further required to make a declaration to the effect that: (i) the company is able to pay its debts as they fall due and that the merger or consolidation is bona fide and not intended to defraud unsecured creditors of the company; (ii) no petition or other similar proceeding has been filed and remains outstanding and that no order has been made or resolution adopted to wind up the company in any jurisdiction; (iii) no receiver, trustee, administrator or other similar person has been appointed in any jurisdiction and is acting in respect of the company, its affairs or its property or any part thereof; (iv) no scheme, order, compromise or other similar arrangement has been entered into or made in any jurisdiction whereby the rights of creditors of the company are and continue to be suspended or restricted; (v) in the case of constituent company that is not a surviving company, the constituent company has retired from any fiduciary office held or will do so immediately prior to the merger or consolidation; and (vi) where relevant, the company has complied with any applicable requirements under Cayman Islands regulatory laws. If the Cayman Islands Registrar of Companies is satisfied that the requirements of the Companies Act (which includes certain other formalities) have been complied with, the Registrar of Companies will register the plan of merger or consolidation.

Where the merger or consolidation involves a foreign company, the procedure is similar, save that with respect to the foreign company, the directors of the Cayman Islands exempted company are required to make a declaration to the effect that, having made due enquiry, they are of the opinion that the requirements set out below have been met: (i) that the merger or consolidation is permitted or not prohibited by the constitutional documents of the foreign company and by the laws of the jurisdiction in which the foreign company is incorporated, and that those laws and any requirements of those constitutional documents have been or will be complied with; (ii) that no petition or other similar proceeding has been filed and remains outstanding or order made or resolution adopted to wind up or liquidate the foreign company in any jurisdictions; (iii) that no receiver, trustee, administrator or other similar person has been appointed in any jurisdiction and is acting in respect of the foreign company, its affairs or its property or any part thereof; (iv) that no scheme, order, compromise or other similar arrangement has been entered into or made in any jurisdiction whereby the rights of creditors of the foreign company are and continue to be suspended or restricted; and (v) that there is no other reason why it would be against the public interest to permit the merger or consolidation.

Where the surviving company is the Cayman Islands exempted company, the directors of the Cayman Islands exempted company are further required to make a declaration to the effect that, having made due enquiry, they are of the opinion that the requirements set out below have been met: (i) that the foreign company is able to pay its debts as they fall due and that the merger or consolidated is bona fide and not intended to defraud unsecured creditors of the foreign company; (ii) that in respect of the transfer of any security interest granted by the foreign company to the surviving or consolidated company (a) consent or approval to the transfer has been obtained, released or waived; (b) the transfer is permitted by and has been approved in accordance with the constitutional documents of the foreign company; and (c) the laws of the jurisdiction of the foreign company with respect to the transfer have been or will be complied with; (iii) that the foreign company will, upon the merger or consolidation becoming effective, cease to be incorporated, registered or exist under the laws of the relevant foreign jurisdiction; and (iv) that there is no other reason why it would be against the public interest to permit the merger or consolidation.

Where the above procedures are adopted, the Companies Act provides for a right of dissenting shareholders to be paid a payment of the fair value of his shares upon their dissenting to the merger or consolidation if they follow a prescribed procedure. In essence, that procedure is as follows: (a) the shareholder must give his written objection to the merger or consolidation to the constituent company before the vote on the merger or consolidation, including a statement that the shareholder proposes to demand payment for his shares if the merger or consolidation is authorized by the vote; (b) within 20 days following the date on which the merger or consolidation is approved by the shareholders, the constituent company must give written notice to each shareholder who made a written objection; (c) a shareholder must within 20 days following receipt of such notice from the constituent company, give the constituent company a written notice of his intention to dissent including, among other details, a demand for payment of the fair value of his shares; (d) within seven days following the date of the expiration of the period set out in paragraph (b) above or seven days following the date on which the plan of merger or consolidation is filed, whichever is later, the constituent company, the surviving company or the consolidated company must make a written offer to each dissenting shareholder to purchase his shares at a price that the company determines is the fair value and if the company and the shareholder agree the price within 30 days following the date on which the offer was made, the company must pay the shareholder such amount; and (e) if the company and the shareholder fail to agree a price within such 30 day period, within 20 days following the date on which such 30 day period expires, the company (and any dissenting shareholder) must file a petition with the Cayman Islands Grand Court to determine the fair value and such petition must be accompanied by a list of the names and addresses of the dissenting shareholders with whom agreements as to the fair value of their shares have not been reached by the company. At the hearing of that petition, the court has the power to determine the fair value of the shares together with a fair rate of interest, if any, to be paid by the company upon the amount determined to be the fair value. Any dissenting shareholder whose name appears on the list filed by the company may participate fully in all proceedings until the determination of fair value is reached. These rights of a dissenting shareholder are not available in certain circumstances, for example, to dissenters holding shares of any class in respect of which an open market exists on a recognized stock exchange or recognized interdealer quotation system at the relevant date or where the consideration for such shares to be contributed are shares of any company listed on a national securities exchange or shares of the surviving or consolidated company.

Moreover, Cayman Islands law has separate statutory provisions that facilitate the reconstruction or amalgamation of companies in certain circumstances, schemes of arrangement will generally be more suited for complex mergers or other transactions involving widely held companies, commonly referred to in the Cayman Islands as a “scheme of arrangement” which may be tantamount to a merger. In the event that a merger was sought pursuant to a scheme of arrangement (the procedures for which are more rigorous and take longer to complete than the procedures typically required to consummate a merger in the United States), the arrangement in question must be approved by (a) in respect of creditor compromises or arrangements, a majority in number of each class of creditors with whom the arrangement is to be made and who must in addition represent three-fourths in value of each such class of creditors that are present and voting either in person or by proxy at an annual general meeting, or an extraordinary general meeting, summoned for that purpose or (b) in respect of shareholder compromises or arrangements, shareholders representing three-fourths in value of each such class of shareholders that are present and voting either in person or by proxy at an annual general meeting, or an extraordinary general meeting, summoned for that purpose. The convening of the meetings and subsequently the terms of the arrangement must be sanctioned by the Grand Court of the Cayman Islands. While a dissenting shareholder would have the right to express to the court the view that the transaction should not be approved, the court can be expected to approve the arrangement if it satisfies itself that:

If a scheme of arrangement or takeover offer (as described below) is approved, any dissenting shareholder would have no rights comparable to appraisal rights (providing rights to receive payment in cash for the judicially determined value of the shares), which would otherwise ordinarily be available to dissenting shareholders of United States corporations.

Squeeze-out Provisions.    When a takeover offer is made and accepted by holders of 90% of the shares to whom the offer relates within four months, the offeror may, within a two-month period, require the holders of the remaining shares to transfer such shares on the terms of the offer. An objection can be made to the Grand Court of the Cayman Islands, but this is unlikely to succeed unless there is evidence of fraud, bad faith, collusion or inequitable treatment of the shareholders.

Further, transactions similar to a merger, reconstruction and/or an amalgamation may in some circumstances be achieved through means other than these statutory provisions, such as a share capital exchange, asset acquisition or control, or through contractual arrangements of an operating business.

Shareholders’ Suits.    Derivative actions have been brought in the Cayman Islands courts, and the Cayman Islands courts have confirmed the availability for such actions. In most cases, we will be the proper plaintiff in any claim based on a breach of duty owed to us, and a claim against (for example) our officers or directors usually may not be brought by a shareholder. However, based both on Cayman Islands authorities and on English authorities, which would in all likelihood be of persuasive authority and be applied by a court in the Cayman Islands, exceptions to the foregoing principle apply in circumstances in which:

A shareholder may have a direct right of action against us where the individual rights of that shareholder have been infringed or are about to be infringed.

Enforcement of Civil Liabilities.    The Cayman Islands has a different body of securities laws as compared to the United States and provides less protection to investors. Additionally, Cayman Islands companies may not have standing to sue before the Federal courts of the United States.

The courts of the Cayman Islands are unlikely (i) to recognize or enforce against us judgments of courts of the United States predicated upon the civil liability provisions of the federal securities laws of the United States or any state; and (ii) in original actions brought in the Cayman Islands, to impose liabilities against us predicated upon the civil liability provisions of the federal securities laws of the United States or any state, so far as the liabilities imposed by those provisions are penal in nature. In those circumstances, although there is no statutory enforcement in the Cayman Islands of judgments obtained in the United States, the courts of the Cayman Islands will recognize and enforce a foreign money judgment of a foreign court of competent jurisdiction without retrial on the merits based on the principle that a judgment of a competent foreign court imposes upon the judgment debtor an obligation to pay the sum for which judgment has been given provided certain conditions are met. For a foreign judgment to be enforced in the Cayman Islands, such judgment must be final and conclusive and for a liquidated sum, and must not be in respect of taxes or a fine or penalty, inconsistent with a Cayman Islands judgment in respect of the same matter, impeachable on the grounds of fraud or obtained in a manner, and or be of a kind the enforcement of which is, contrary to natural justice or the public policy of the Cayman Islands (awards of punitive or multiple damages may well be held to be contrary to public policy). A Cayman Islands Court may stay enforcement proceedings if concurrent proceedings are being brought elsewhere.

Special Considerations for Exempted Companies.    We are an exempted company with limited liability under the Companies Act. The Companies Act distinguishes between ordinary resident companies and exempted companies. Any company that is registered in the Cayman Islands but conducts business mainly outside of the Cayman Islands may apply to be registered as an exempted company. The requirements for an exempted company are essentially the same as for an ordinary company except for the exemptions and privileges listed below:

“Limited liability” means that the liability of each shareholder is limited to the amount unpaid by the shareholder on the shares of the company (except in exceptional circumstances, such as involving fraud, the establishment of an agency relationship or an illegal or improper purpose or other circumstances in which a court may be prepared to pierce or lift the corporate veil).

Our Amended and Restated Memorandum and Articles of Association

Our amended and restated memorandum and articles of association contain certain requirements and restrictions that will apply to us until the consummation of our initial business combination. Our amended and restated memorandum and articles of association provide that, if we seek to amend our amended and restated memorandum and articles of association (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 the completion window or (B) with respect to any other material provisions relating to shareholders’ rights or pre-initial business combination activity, we will provide public shareholders with the opportunity to redeem their public shares in connection with any such amendment. Our sponsor, officers and directors have agreed to waive any redemption rights with respect to any founder shares and any public shares held by them in connection with any such amendment. Specifically, our amended and restated memorandum and articles of association provide, among other things, that:

These provisions cannot be amended without the approval of a special resolution under Cayman Islands law, which requires the affirmative vote of shareholders holding at least two-thirds of our ordinary shares who attend and vote at a general meeting of the company. A quorum for such general meeting will consist of the holders present in person or by proxy of shares of the company representing a majority of the issued and outstanding shares entitled to vote at such general meeting.

Unless specified in our amended and restated memorandum and articles of association, or as required by applicable law or stock exchange rules, the affirmative vote of shareholders holding of a majority of the issued and outstanding ordinary shares that are voted is required to approve any such matter voted on by our shareholders.

Certain Anti-Takeover Provisions of our Amended and Restated Memorandum and Articles of Association

Our amended and restated memorandum and articles of association provide that our board of directors will be classified into three classes of directors. As a result, in most circumstances, a person can gain control of our board only by successfully engaging in a proxy contest at two or more annual general meetings.

Our authorized but unissued ordinary shares are available for future issuances without shareholder approval and could be utilized for a variety of corporate purposes, including future offerings to raise additional capital, acquisitions and employee benefit plans. The existence of authorized but unissued and unreserved ordinary shares could render more difficult or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger or otherwise.

LISTING OF SECURITIES

Our units are listed on Nasdaq under the symbol “ATIIU” and, once the ordinary shares and warrants begin separate trading, they are expected to be listed on Nasdaq under the symbols “ATII” and “ATIIW,” respectively.
