 Exhibit 4.5 

DESCRIPTION OF SECURITIES 

The following description of the securities of Altimeter Growth Corp. 2 (the “Company,” “we” or “us”) is a
summary and does not purport to be complete. It is subject to and qualified in its entirety by reference to the Company’s amended and restated memorandum and article of association, which is incorporated by reference as an exhibit to the Annual
Report on Form 10-K of which this Exhibit 4.5 is a part. We encourage you to read the memorandum and articles of association for additional information. 

We are a Cayman Islands exempted company and our affairs are governed by our amended and restated memorandum and articles of association, the
Companies Law and the common law of the Cayman Islands. Pursuant to our amended and restated memorandum and articles of association, we are authorized to issue 200,000,000 Class A ordinary shares and 20,000,000 Class B ordinary shares, as
well as 1,000,000 preference shares, $0.0001 par value each. The following description summarizes the material terms of our shares as set out more particularly in our amended and restated memorandum and articles of association. Because it is only a
summary, it may not contain all the information that is important to you. 
 Ordinary Shares 

 

	 	•	 	 57,350,000 of our ordinary shares are outstanding including: 

 

	 	•	 	 45,000,000 Class A ordinary shares; 

 

	 	•	 	 1,100,000 private placement shares; and 

 

	 	•	 	 11,250,000 Class B ordinary shares held by our sponsor and our independent directors. 

Ordinary shareholders of record are entitled to one vote for each share held on all matters to be voted on by shareholders. Except as
described below, holders of Class A ordinary shares and holders of Class B ordinary shares will vote together as a single class on all matters submitted to a vote of our shareholders except as required by law. Unless specified in our
amended and restated memorandum and articles of association, or as required by applicable provisions of the Companies Law 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. Approval of certain actions will require a special resolution under Cayman Islands law, being the affirmative vote of at least two-thirds of our ordinary
shares that are voted, and pursuant to our amended and restated memorandum and articles of association; such actions include amending our amended and restated memorandum and articles of association and approving a statutory merger or consolidation
with another company. There is no cumulative voting with respect to the appointment of directors, with the result that the holders of more than 50% of the shares voted for the appointment of directors can appoint all of the 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. Before our initial business combination, only holders of our founder shares will have the right to
vote to appoint directors. Holders of our public shares and private placement shares will not be entitled to vote to appoint directors during such time. In addition, before the completion of an initial business combination, holders of a majority of
our founder shares may remove a member of the board of directors for any reason. In addition, in a vote to continue the company in a jurisdiction outside the Cayman Islands (which requires the approval of at least two thirds of the votes of all
ordinary shares), holders of our Class B ordinary shares will have ten votes for every Class B ordinary share and holders of our Class A ordinary shares will have one vote for every Class A ordinary share. The provisions of our
amended and restated memorandum and articles of association governing the appointment or removal of directors before our initial business combination and our continuation in a jurisdiction outside the Cayman Islands before our initial business
combination may only be amended by a special resolution passed by not less than two-thirds of the ordinary shares who attend and vote at our general meeting which shall include the affirmative vote of a simple
majority of our Class B ordinary shares. 

 Because our amended and restated memorandum and articles of association authorize the
issuance of up to 200,000,000 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 Class A ordinary shares which we
will be 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 the NYSE 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 the NYSE. There is no requirement under the Companies Law for us to hold annual or general meetings to appoint directors. We may not hold an annual general meeting to appoint new directors before the
closing of our initial business combination. Before the completion of an initial business combination, any vacancy on the board of directors may be filled by a nominee chosen by holders of a majority of our founder shares. In addition, before the
completion of an initial business combination, holders of a majority of our founder shares may remove a member of the board of directors for any reason. 

Our public shareholders may redeem all or a portion of their Class A ordinary shares upon our initial business combination’s
completion at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account calculated as of two business days before the closing 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, if any, divided by the number of the then-outstanding public shares, subject to the limitations described herein. The amount in the
trust account was initially $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 underwriters.
The redemption rights will include the requirement that a beneficial owner must identify itself in order to valid redeem its shares. Our sponsor and each member of our management team have entered into an agreement with us, pursuant to which they
have agreed to waive their redemption rights with respect to any founder shares, public shares and private placement shares held by them in connection with (i) the completion of our initial business combination, and (ii) a shareholder vote
to approve an amendment to our amended and restated memorandum and articles of association (A) that would modify the substance or timing of our obligation to provide holders of our Class A ordinary shares the right to have their shares
redeemed 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 (or 27 months, as applicable) from the closing of our initial public offering
or during any Extension Period or (B) with respect to any other provision relating to the rights of holders of our Class A ordinary shares. 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 applicable law or stock exchange listing requirements and we do not decide to hold a shareholder vote for business or other reasons, we will, pursuant to our 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 before completing our initial business combination. Our 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, a shareholder approval of the transaction is required by
applicable law or stock exchange listing requirements, or we decide to obtain shareholder approval for business or other 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, which requires the
affirmative vote of a majority of the shareholders who attend and vote at a general meeting of the company. However, the participation of our sponsor, officers, directors, advisors 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 initial 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. Our amended and restated memorandum and articles of
association require that at least five days’ notice will be given of any general meeting.

 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 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 Excess Shares, without our prior consent.
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 our initial 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, we will complete our
initial business combination only if we obtain the approval of an ordinary resolution under Cayman Islands law, which requires the affirmative vote of a majority of the shareholders who attend and vote at a general meeting of the company. In such
case, our sponsor and each member of our management team have agreed to vote any founder shares, public shares and private placement shares held by them 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 vote at all. 
 Pursuant to our
amended and restated memorandum and articles of association, if we have not consummated an initial business combination within 24 months (or 27 months, as applicable) from the closing of our initial public offering, we will (i) cease all
operations except for the purpose of winding up; (ii) 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 earned on the funds held in the trust account and not previously released to us to pay our taxes, if any (less up to $100,000 of interest to pay dissolution
expenses) divided by the number of the then-outstanding public shares, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any); 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 and each member of our management team have entered into an agreement with us, pursuant to which they have agreed to waive their rights to liquidating
distributions from the trust account with respect to any founder shares and private placement shares they hold if we fail to consummate an initial business combination within 24 months (or 27 months, as applicable) from the closing of our initial
public offering or during any Extension Period (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
prescribed time frame). Our amended and restated memorandum and articles of association provide that, if we wind up for any other reason before the closing of our initial business combination, we will follow the foregoing procedures with respect to
the liquidation of the trust account as promptly as reasonably possible but not more than ten business days thereafter, subject to applicable Cayman Islands law. 

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 public shareholders with the opportunity to redeem their public shares for cash at a per share price equal to the aggregate
amount then on deposit in the trust account, including interest earned on the funds held in the trust account and not previously released to us to pay our taxes, if any, divided by the number of the then-outstanding public shares, upon the
completion of our initial business combination, subject to the limitations described herein. 
 Private Placement Shares 

The private placement shares will not be transferable, assignable or salable until 30 days after the completion of our initial business
combination (except pursuant to limited exceptions to our officers and directors and other persons or entities affiliated with our sponsor). Holders of our private placement shares are entitled to 

  
 -3- 

 
certain registration rights. If we do not consummate an initial business combination within 24 months (or 27 months, as applicable) from the closing of our initial public offering, the proceeds
from the sale of the private placement shares 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 private placement shares will be worthless. Further, if we seek
shareholder approval, we will complete our initial business combination only if a majority of the ordinary shares, represented in person or by proxy and entitled to vote thereon, voted at a shareholder meeting are voted in favor of the business
combination. In such case, our sponsor and each member of our management team have agreed to vote any founder shares, public shares and private placement shares held by them in favor of our initial business combination. Otherwise, the private
placement shares are identical to the Class A ordinary shares sold in our initial public offering. 
 Our sponsor and our management
team have agreed not to transfer, assign or sell any of their private placement shares until 30 days after the completion of our initial business combination, except, among other limited exceptions, to our officers and directors and other persons or
entities affiliated with our sponsor. 
 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 $2,000,000 of such loans may be convertible into shares
of the post business combination entity at a price of $10.00 per share at the option of the lender. Such shares would be identical to the private placement shares. 

Founder Shares 
 The founder shares are
designated as Class B ordinary shares and, except as described below, are identical to the Class A ordinary shares sold in our initial public offering, and holders of founder shares have the same shareholder rights as public shareholders,
except that: (a) before our initial business combination, only holders of the founder shares have the right to vote to appoint directors and holders of a majority of our founder shares may remove a member of the board of directors for any
reason; (b) the founder shares are subject to certain transfer restrictions, as described in more detail below; (c) in a vote to continue the company in a jurisdiction outside the Cayman Islands (which requires the approval of at least two
thirds of the votes of all ordinary shares), holders of our founder shares will have ten votes for every founder share and holders of our Class A ordinary shares will have one vote for every Class A ordinary share; (d) our sponsor and
each member of our management team have entered into an agreement with us, pursuant to which they have agreed to (i) waive their redemption rights with respect to their founder shares (ii) to waive their redemption rights with respect to
their founder shares and public shares in connection with a shareholder vote to approve an amendment to our amended and restated memorandum and articles of association (A) that would modify the substance or timing of our obligation to provide
holders of our Class A ordinary shares the right to have their shares redeemed 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
(or 27 months, as applicable) from the closing of our initial public offering or (B) with respect to any other provision relating to the rights of holders of our Class A ordinary shares; and (iii) waive their rights to liquidating
distributions from the trust account with respect to any founder shares and private placement shares they hold if we fail to consummate an initial business combination within 24 months (or 27 months, as applicable) from the closing of our initial
public offering or during any Extension Period (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
prescribed time frame); (e) the founder shares will automatically convert into our Class A ordinary shares upon our initial business combination or earlier at the option of the holders thereof as described herein; and (f) the founder
shares are entitled to registration rights. 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, which requires the affirmative vote of
a majority of the shareholders who attend and vote at a general meeting of the company. In such case, our sponsor and each member of our management team have agreed to vote any founder shares, public shares and private placement shares held by them
in favor of our initial business combination. 
 The founder shares are designated as Class B ordinary shares and will automatically
convert into Class A ordinary shares (which such Class A ordinary shares delivered upon conversion will not have redemption rights or be entitled to liquidating distributions from the trust account if we do not consummate an initial
business combination) upon our initial business combination or earlier at the option of the holders thereof at a ratio such that 

  
 -4- 

 
the number of Class A ordinary shares issuable upon conversion of all founder shares will equal, in the aggregate, on an as-converted basis, 20% of
the sum of (i) the total number of ordinary shares issued and outstanding upon completion of our initial public offering, plus (ii) the total number of Class A ordinary shares issued or deemed issued or issuable upon conversion or
exercise of any equity-linked securities or rights issued or deemed issued, by the Company in connection with or in relation to the closing of the initial business combination, excluding any forward purchase shares and Class A ordinary shares
or equity-linked securities exercisable for or convertible into Class A ordinary shares issued, deemed issued, or to be issued, to any seller in the initial business combination and any private placement shares issued to our sponsor, its
affiliates or any member of our management team, including upon conversion of working capital loans. In no event will the Class B ordinary shares convert into Class A ordinary shares at a rate of less than one-to-one. 
 Except as described herein, our sponsor and our directors and executive officers
have agreed not to transfer, assign or sell any of their founder shares until earliest of (A) one year after the completion of our initial business combination and (B) after our initial business combination, (x) if the closing price
of our Class A ordinary shares equals or exceeds $12.00 per share (as adjusted for share sub-divisions, share capitalizations, reorganizations, recapitalizations and the like) for any 20 trading days
within any 30-trading day period commencing at least 120 days after our initial business combination, or (y) the date on which we complete a liquidation, merger, share exchange 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. Any permitted transferees would be subject to the same restrictions and other agreements of our
sponsor and our directors and executive officers with respect to any founder shares and private placement shares. 
 Before our initial
business combination, only holders of our founder shares will have the right to vote to appoint directors. Holders of our public shares and private placement shares will not be entitled to vote to appoint directors during such time. In addition,
before the completion of an 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 amended and restated memorandum and articles of association
may only be amended by a special resolution passed by not less than two-thirds of our ordinary shares who attend and vote at our general meeting which shall include the affirmative vote of a simple majority of
our Class B ordinary shares. With respect to any other matter submitted to a vote of our shareholders, including any vote in connection with our initial business combination, except as required by law, holders of our founder shares and holders
of our public shares will vote together as a single class, with each share entitling the holder to one vote. 
 Register of Members 

 

	 	•	 	 Under Cayman Islands law, we must keep a register of members and there will 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 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. 

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. Upon the closing of our initial public offering, the register of members was updated to reflect the issue of shares by us, and the shareholders recorded in the register of members are 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 

  
 -5- 

 
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 was 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 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 issued and 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. 
 Forward
Purchase Shares 
 We have entered into a forward purchase agreement pursuant to which Altimeter Partners Fund, L.P. (the “forward
purchase investor”) has agreed to subscribe for up to an aggregate of 5,000,000 forward purchase shares for $10.00 per share, or up to $50,000,000 in the aggregate, in a private placement to close substantially concurrently with our initial
business combination’s closing. The obligations under the forward purchase agreement do not depend on whether any Class A ordinary shares are redeemed by our public shareholders. We will determine in our sole discretion the specific number
of forward purchase shares that we sell to the forward purchase investor, if any. 
 The forward purchase agreement also provides that the
forward purchase investor is entitled to registration rights with respect to the forward purchase shares and any other Class A ordinary shares acquired by the forward purchase investor, including any acquired after we complete our initial
business combination. We may use the proceeds from our sale of the forward purchase shares as part of the consideration to the sellers in our initial business combination, and/or for expenses in connection with our initial business combination,
and/or for working capital in the post-business-combination company. The forward purchase investor is obligated to buy the forward purchase shares, regardless of whether our public shareholders redeem any Class A ordinary shares, and our sale
of any forward purchase shares is intended to give us a minimum funding level for our initial business combination. The forward purchase shares will be issued only in connection with the initial business combination’s closing. 

The forward purchase agreement provides that the forward purchase investor may decline to purchase some or all of the forward purchase shares
if our sponsor and our sponsor’s affiliates collectively own 25% or more of our outstanding shares when we initiate the private placement sale of forward purchase shares. 

Dividends 
 We have not paid any cash
dividends on our ordinary shares to date and do not intend to pay cash dividends before the completion of our 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 condition after completion of our initial business combination. The payment of any cash dividends after our initial business combination will be within the discretion of our board of directors at such time. If we
incur any indebtedness in connection with a business combination, our ability to declare dividends may be limited by restrictive covenants we may agree to in connection therewith.

 Our Transfer Agent 

The transfer agent for our ordinary shares is Continental Stock Transfer & Trust Company. We have agreed to indemnify Continental
Stock Transfer & Trust Company in its roles as transfer agent, its agents and each of its shareholders, directors, officers and employees against all claims and losses that may arise out of acts performed or omitted for its activities in
that capacity, except for any claims and losses due to any gross negligence or intentional misconduct of the indemnified person or entity. 
 Certain
Differences in Corporate Law 
 Cayman Islands companies are governed by the Companies Law. The Companies Law 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 Law
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 Law 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 66 2/3% in value 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. 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. If the Cayman Islands Registrar of Companies is satisfied that the requirements of the Companies Law (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; and (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. 
 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. 

  
 -7- 

 Where the above procedures are adopted, the Companies Law 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 majority in number of each class of shareholders and creditors with whom the arrangement is to be made and who must in addition represent three-fourths in value of each such class of shareholders or
creditors, as the case may be, 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: 
  

	 	•	 	 we are not proposing to act illegally or beyond the scope of our corporate authority and the statutory provisions
as to majority vote have been complied with; 

  

	 	•	 	 the shareholders have been fairly represented at the meeting in question; 

 

	 	•	 	 the arrangement is such as a businessman would reasonably approve; and 

 

	 	•	 	 the arrangement is not one that would more properly be sanctioned under some other provision of the Companies Law
or that would amount to a “fraud on the minority.”

 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. Maples and Calder, our Cayman Islands legal counsel, is not aware of any reported class action having been
brought in a Cayman Islands court. 
 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 company is acting, or proposing to act, illegally or beyond the scope of its authority; 

 

	 	•	 	 the act complained of, although not beyond the scope of the authority, could be effected if duly authorized by
more than the number of votes which have actually been obtained; or 

  

	 	•	 	 those who control the company are perpetrating a “fraud on the minority.” 

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. 

We have been advised by Maples and Calder, our Cayman Islands legal counsel, that 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 Law. The Companies Law 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: 

 

	 	•	 	 an exempted company does not have to file an annual return on its shareholders with the Registrar of Companies;

  

	 	•	 	 an exempted company’s register of members is not open to inspection; 

 

	 	•	 	 an exempted company does not have to hold an annual general meeting; 

 

	 	•	 	 an exempted company may issue shares with no par value; 

 

	 	•	 	 an exempted company may obtain an undertaking against the imposition of any future taxation (such undertakings
are usually given for 20 years in the first instance); 

  

	 	•	 	 an exempted company may register by way of continuation in another jurisdiction and be deregistered in the Cayman
Islands; 

  

	 	•	 	 an exempted company may register as a limited duration company; and 

 

	 	•	 	 an exempted company may register as a segregated portfolio company. 

“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).

 Amended and Restated Memorandum and Articles of Association 

Our amended and restated memorandum and articles of association contain provisions designed to provide certain rights and protections that will
apply to us until the completion of our initial business combination. These provisions cannot be amended without a special resolution under Cayman Islands law. As a matter of Cayman Islands law, a resolution is deemed to be a special resolution
where it has been approved by either (i) the affirmative vote of at least two-thirds (or any higher threshold specified in a company’s articles of association) of a company’s shareholders
entitled to vote and so voting at a general meeting for which notice specifying the intention to propose the resolution as a special resolution has been given; or (ii) if so authorized by a company’s articles of association, by a unanimous
written resolution of all of the company’s shareholders. Other than as described above, our amended and restated memorandum and articles of association provide that special resolutions must be approved either by at least two-thirds of our shareholders who attend and vote at a general meeting of the company (i.e., the lowest threshold permissible under Cayman Islands law), or by a unanimous written resolution of all of our
shareholders. 
 Our initial shareholders and their permitted transferees, if any, who collectively beneficially own 20% of our ordinary
shares (excluding the private placement shares and assuming they did not purchase any public shares in our initial public offering or since), will participate in any vote to amend our amended and restated memorandum and articles of association and
will have the discretion to vote in any manner they choose. Specifically, our amended and restated memorandum and articles of association provide, among other things, that: 
  

	 	•	 	 If we have not consummated an initial business combination within 24 months (or 27 months, as applicable) from
the closing of our initial public offering, 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, redeem the public shares, at a per-share price, payable in cash, equal to the aggregate amount 

  
 -10- 

	 	 
then on deposit in the trust account, including interest earned on the funds held in the trust account and not previously released to us to pay our taxes that were paid by us or are payable by
us, if any (less up to $100,000 of interest to pay dissolution expenses) divided by the number of the then-outstanding public shares, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right
to receive further liquidation distributions, if any); 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; 

  

	 	•	 	 Before or in connection with our initial business combination, we may not issue additional securities that would
entitle the holders thereof to (i) receive funds from the trust account or (ii) vote as a class with our public shares (a) on our initial business combination or on any other proposal presented to shareholders before or in connection
with the completion of an initial business combination or (b) to approve an amendment to our amended and restated memorandum and articles of association to (x) extend the time we have to consummate a business combination beyond 24 months
(or 27 months, as applicable) from the closing of our initial public offering or (y) amend the foregoing provisions; 

  

	 	•	 	 Although we do not intend to enter into a business combination with a target business that is affiliated with our
sponsor, Founder, our directors or our officers, we are not prohibited from doing so. In the event we enter into such a transaction, we, or a committee of independent directors, if required by applicable law or based upon the determination of our
board of directors or a committee thereof, will obtain an opinion from independent investment banking firm or another independent entity that commonly renders valuation opinions that such a business combination is fair to our company from a
financial point of view; 

  

	 	•	 	 If a shareholder vote on our initial business combination is not required by applicable law or stock exchange
listing requirements and we do not decide to hold a shareholder vote for business or other reasons, we will offer to redeem our public shares pursuant to Rule 13e-4 and Regulation 14E of the Exchange Act, and
will file tender offer documents with the SEC before completing our initial business combination which contain substantially the same financial and other information about our initial business combination and the redemption rights as is required
under Regulation 14A of the Exchange Act; 

  

	 	•	 	 So long as our securities are then listed on the NYSE, our initial business combination must be with one or more
target businesses that together have an aggregate fair market value of at least 80% of the value of the trust account (excluding any deferred underwriters fees and taxes payable on the income earned on the trust account) at the time of the agreement
to enter into the initial business combination; 

  

	 	•	 	 If our shareholders approve an amendment to our amended and restated memorandum and articles of association
(A) that would modify the substance or timing of our obligation to provide holders of our Class A ordinary shares the right to have their shares redeemed 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 (or 27 months, as applicable) from the closing of our initial public offering or (B) with respect to any other provision relating to the rights of holders of our
Class A ordinary shares, we will provide our public shareholders with the opportunity to redeem all or a portion of their ordinary shares upon such approval at a per-share price, payable in cash, equal to
the aggregate amount then on deposit in the trust account, including interest earned on the funds held in the trust account and not previously released to us to pay our taxes, if any, divided by the number of the then-outstanding public shares,
subject to the limitations described herein; and 

  

	 	•	 	 We will not effectuate our initial business combination solely with another blank check company or a similar
company with nominal operations. 

 In addition, our amended and restated memorandum and articles of association provide
that under no circumstances will we redeem our public shares in an amount that would cause our net tangible assets to be less than $5,000,001. 

  
 -11- 

 The Companies Law permits a company incorporated in the Cayman Islands to amend its
memorandum and articles of association with the approval of a special resolution which requires the approval of the holders of at least two-thirds of such company’s issued and outstanding ordinary shares
who attend and vote at a general meeting or by way of unanimous written resolution. A company’s articles of association may specify that the approval of a higher majority is required but, provided the approval of the required majority is
obtained, any Cayman Islands exempted company may amend its memorandum and articles of association regardless of whether its memorandum and articles of association provide otherwise. 

Accordingly, although we could amend any of the provisions relating to our structure and business plan which are contained in our amended and
restated memorandum and articles of association, we view all of these provisions as binding obligations to our shareholders and neither we, nor our officers or directors, will take any action to amend or waive any of these provisions unless we
provide dissenting public shareholders with the opportunity to redeem their public shares. 
 Privacy Notice 

Introduction 
 This privacy notice puts our
shareholders on notice that through your investment in the Company you will provide us with certain personal information which constitutes personal data within the meaning of the DPL (“personal data”). In the following discussion, the
“company” refers to us and our affiliates and/or delegates, except where the context requires otherwise. 
 Investor Data 

We will collect, use, disclose, retain and secure personal data to the extent reasonably required only and within the parameters that could be
reasonably expected during the normal course of business. We will only process, disclose, transfer or retain personal data to the extent legitimately required to conduct our activities of on an ongoing basis or to comply with legal and regulatory
obligations to which we are subject. We will only transfer personal data in accordance with the requirements of the DPL, and will apply appropriate technical and organizational information security measures designed to protect against unauthorized
or unlawful processing of the personal data and against the accidental loss, destruction or damage to the personal data. 
 In our use of
this personal data, we will be characterized as a “data controller” for the purposes of the DPL, while our affiliates and service providers who may receive this personal data from us in the conduct of our activities may either act as our
“data processors” for the purposes of the DPL or may process personal information for their own lawful purposes in connection with services provided to us. 

We may also obtain personal data from other public sources. Personal data includes, without limitation, the following information relating to
a shareholder and/or any individuals connected with a shareholder as an investor: name, residential address, email address, contact details, corporate contact information, signature, nationality, place of birth, date of birth, tax identification,
credit history, correspondence records, passport number, bank account details, source of funds details and details relating to the shareholder’s investment activity. 

Who this Affects 
 If you are a natural
person, this will affect you directly. If you are a corporate investor (including, for these purposes, legal arrangements such as trusts or exempted limited partnerships) that provides us with personal data on individuals connected to you for any
reason in relation to your investment in the company, this will be relevant for those individuals and you should transmit the content of this Privacy Notice to such individuals or otherwise advise them of its content. 

  
 -12- 

 How the Company May Use a Shareholder’s Personal Data 

The company, as the data controller, may collect, store and use personal data for lawful purposes, including, in particular: 

(a) where this is necessary for the performance of our rights and obligations under any purchase agreements; 

(b) where this is necessary for compliance with a legal and regulatory obligation to which we are subject (such as compliance with anti-money
laundering and FATCA/CRS requirements); and/or 
 (c) where this is necessary for the purposes of our legitimate interests and such
interests are not overridden by your interests, fundamental rights or freedoms. 
 Should we wish to use personal data for other specific
purposes (including, if applicable, any purpose that requires your consent), we will contact you. 
 Why We May Transfer Your Personal Data 

In certain circumstances we may be legally obliged to share personal data and other information with respect to your shareholding with the
relevant regulatory authorities such as the Cayman Islands Monetary Authority or the Tax Information Authority. They, in turn, may exchange this information with foreign authorities, including tax authorities. 

We anticipate disclosing personal data to persons who provide services to us and their respective affiliates (which may include certain
entities located outside the United States, the Cayman Islands or the European Economic Area), who will process your personal data on our behalf. 
 The
Data Protection Measures We Take 
 Any transfer of personal data by us or our duly authorized affiliates and/or delegates outside of the
Cayman Islands shall be in accordance with the requirements of the DPL. 
 We and our duly authorized affiliates and/or delegates shall
apply appropriate technical and organizational information security measures designed to protect against unauthorized or unlawful processing of personal data, and against accidental loss or destruction of, or damage to, personal data. 

We shall notify you of any personal data breach that is reasonably likely to result in a risk to your interests, fundamental rights or
freedoms or those data subjects to whom the relevant personal data relates. 
 Certain Anti-Takeover Provisions of our Amended and Restated Memorandum
and Articles of Association 
 Our authorized but unissued Class A ordinary shares and preference shares will be 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 Class A ordinary shares and preference 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. 

Securities Eligible for Future Sale 
 We
currently have 46,100,000 Class A ordinary shares issued and outstanding on an as-converted basis. Of these shares, the 45,000,000 Class A ordinary shares sold in our initial public offering are
freely tradable without restriction or further registration under the Securities Act, except for any Class A ordinary shares purchased by one of our affiliates within the meaning of Rule 144 under the Securities Act. All of the 11,250,000
outstanding founder shares and all of the 1,100,000 outstanding private placement shares are restricted securities under Rule 144, in that they were issued in private transactions not involving a public offering. 

  
 -13- 

 Upon the closing of the sale of the forward purchase shares, all of the forward purchase
shares will be restricted securities under Rule 144. 
 Rule 144 

Pursuant to Rule 144, a person who has beneficially owned restricted shares for at least six months would be entitled to sell their securities
provided that (i) such person is not deemed to have been one of our affiliates at the time of, or at any time during the three months preceding, a sale and (ii) we are subject to the Exchange Act periodic reporting requirements for
at least three months before the sale and have filed all required reports under Section 13 or 15(d) of the Exchange Act during the twelve months (or such shorter period as we were required to file reports) preceding the sale. 

Persons who have beneficially owned restricted shares for at least six months but who are our affiliates at the time of, or at any time during
the three months preceding, a sale, would be subject to additional restrictions, by which such person would be entitled to sell within any three-month period only a number of securities that does not exceed the greater of: 

 

	 	•	 	 1% of the total number of ordinary shares then-outstanding, which equals 573,500 shares; or

  

	 	•	 	 the average weekly reported trading volume of the Class A ordinary shares during the four calendar weeks
preceding the filing of a notice on Form 144 with respect to the sale. 

 Sales by our affiliates under Rule 144 are also
limited by manner of sale provisions and notice requirements and to the availability of current public information about us. 
 Restrictions on the Use
of Rule 144 by Shell Companies or Former Shell Companies 
 Rule 144 is not available for the resale of securities initially issued by
shell companies (other than business combination related shell companies) or issuers that have been at any time previously a shell company. However, Rule 144 also includes an important exception to this prohibition if the following conditions are
met: 
  

	 	•	 	 the issuer of the securities that was formerly a shell company has ceased to be a shell company;

  

	 	•	 	 the issuer of the securities is subject to the reporting requirements of Section 13 or 15(d) of the Exchange
Act; 

  

	 	•	 	 the issuer of the securities has filed all Exchange Act reports and material required to be filed, as applicable,
during the preceding twelve months (or such shorter period that the issuer was required to file such reports and materials), other than Form 8-K reports; and 

 

	 	•	 	 at least one year has elapsed from the time that the issuer filed current Form 10 type information with the SEC
reflecting its status as an entity that is not a shell company. 

 As a result, our sponsor will be able to sell its
founder shares and private placement shares, as applicable, pursuant to Rule 144 without registration one year after we have completed our initial business combination. 

Registration and Shareholder Rights 
 The
holders of the founder shares and private placement shares, including any private placement shares that may be issued upon conversion of working capital loans and any Class A ordinary shares issuable upon conversion of founder shares, are
entitled to registration rights pursuant to a registration and shareholder rights agreement. The holders of these securities are entitled to make up to three demands, excluding short form demands, that we register such securities. In addition, the
holders have certain “piggy-back” registration rights with respect to registration statements filed after our completion of our initial business combination. However, the registration and shareholder rights agreement provides that we will
not permit any registration statement filed under the Securities Act to become effective until termination of the applicable lockup period, which occurs (i) in the case of the founder shares, as described in the following paragraph, and
(ii) in the case of the private placement shares, 30 days after the completion of our initial business combination. We will bear the expenses incurred in connection with the filing of any such registration statements. 

  
 -14- 

 Pursuant to the forward purchase agreement, we have agreed that we will use our commercially
reasonable efforts to (i) within 30 days after the closing of the initial business combination, file a registration statement with the SEC for a secondary offering of the forward purchase investor’s forward purchase shares and any other
Class A ordinary shares acquired by the forward purchase investor, including any acquisitions after we complete our initial business combination, (ii) cause such registration statement to be declared effective promptly thereafter, but in
no event later than 90 days after the closing of the initial business combination and (iii) maintain the effectiveness of such registration statement and to ensure the registration statement does not contain a material omission or misstatement,
including by way of amendment or other update, as required, until the earlier of (A) the date on which the forward purchase investor ceases to hold the securities covered thereby and (B) the date all of the securities covered thereby can
be sold publicly without restriction or limitation under Rule 144 under the Securities Act, and without the requirement to be in compliance with Rule 144(c)(1) under the Securities Act, subject to certain conditions and limitations set forth in the
forward purchase agreement. We will bear the cost of registering these securities. 
 Except as described herein, our sponsor and our
directors and executive officers have agreed not to transfer, assign or sell their founder shares until the earliest of (A) one year after the completion of our initial business combination and (B) after our initial business combination,
(x) if the closing price of our Class A ordinary shares equals or exceeds $12.00 per share (as adjusted for share sub-divisions, share capitalizations, reorganizations, recapitalizations and the
like) for any 20 trading days within any 30-trading day period commencing at least 120 days after our initial business combination, or (y) the date on which we complete a liquidation, merger, share
exchange 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. Any permitted transferees will be subject to the same restrictions and
other agreements of our sponsor with respect to any founder shares and private placement shares. 
 In addition, pursuant to the
registration and shareholder rights agreement, our sponsor, upon and following closing of an initial business combination, will be entitled to nominate three individuals for appointment to our board of directors, as long as the sponsor holds any
securities covered by the registration and shareholder rights agreement. 
 Listing of Securities 

Our Class A ordinary shares are listed on the NYSE under the symbol “AGCB”.

DESCRIPTION OF THE REGISTRANT’S SECURITIES

REGISTERED PURSUANT TO SECTION 12 OF THE SECURITIES

EXCHANGE ACT OF 1934

 

SINTX Technologies, Inc. (“SINTX,”
“we,” “our,” or “us”) has one class of securities registered under Section 12 of the Securities Exchange
Act of 1934, as amended: our common stock.

 

Authorized Shares of Capital Stock

 

Our Restated Certificate of Incorporation authorizes
us to issue 250,000,000 shares of common stock, par value $0.01 per share, and 130,000,000 shares of preferred stock, par value $0.01
per share. The following is a summary of the rights of our common stock and some of the provisions of our Restated Certificate of Incorporation
and Restated Bylaws, and the Delaware General Corporation Law. Because it is only a summary, it does not contain all the information that
may be important to you and is subject to and qualified in its entirety by our Restated Certificate of Incorporation and our Restated
Bylaws.

 

Our Restated Certificate of Incorporation and our
Restated Bylaws contain certain provisions that are intended to enhance the likelihood of continuity and stability in the composition
of the board of directors, which may have the effect of delaying, deferring or preventing a future takeover or change in control of the
Company unless such takeover or change in control is approved by our board of directors.

 

Common Stock

 

Holders of our common stock are entitled to one vote
for each share held of record on all matters submitted to a vote of the stockholders, and do not have cumulative voting rights. Accordingly,
the holders of a majority of the shares of our common stock entitled to vote can elect all of the directors standing for election. Subject
to preferences that may be applicable to any outstanding shares of preferred stock, holders of our common stock are entitled to receive
ratably such dividends, if any, as may be declared from time to time by our board of directors out of funds legally available for dividend
payments. All outstanding shares of our common stock are fully paid and nonassessable. The holders of common stock have no preferences
or rights of conversion, exchange, pre- emption or other subscription rights. There are no redemption or sinking fund provisions applicable
to our common stock. In the event of any liquidation, dissolution or winding-up of our affairs, holders of our common stock will be entitled
to share ratably in our assets that are remaining after payment or provision for payment of all of our debts and obligations and after
liquidation payments to holders of outstanding shares of preferred stock, if any.

 

The transfer agent and registrar for our common stock
is American Stock Transfer and Trust Company. The transfer agent and the registrar’s address is 59 Maiden Lane, New York, New York
10038.

 

Our common stock is listed on The NASDAQ Capital Market
under the symbol “SINT”.

 

Effects of Anti-Takeover Provisions of Our Restated
Certificate of Incorporation, Our Restated Bylaws and Delaware Law

 

The provisions of (1) Delaware law, (2) our Restated
Certificate of Incorporation and (3) our Restated Bylaws discussed below could discourage or make it more difficult to prevail in a proxy
contest or effect other change in our management or the acquisition of control by a holder of a substantial amount of our voting stock.
It is possible that these provisions could make it more difficult to accomplish, or could deter, transactions that stockholders may otherwise
consider to be in their best interests or our best interests. These provisions are intended to enhance the likelihood of continuity and
stability in the composition of our board of directors and in the policies formulated by the board of directors and to discourage certain
types of transactions that may involve an actual or threatened change in control of our company. These provisions are designed to reduce
our vulnerability to an unsolicited acquisition proposal. These provisions also are intended to discourage certain tactics that may be
used in proxy fights. These provisions also may have the effect of preventing changes in our management.

 

    	 

     

     

Delaware Statutory Business Combinations Provision.
We are subject to the anti-takeover provisions of Section 203 of the Delaware General Corporation Law. In general, Section 203 prohibits
a publicly-held Delaware corporation from engaging in a “business combination” with an “interested stockholder”
for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the business
combination is, or the transaction in which the person became an interested stockholder was, approved in a prescribed manner or another
prescribed exception applies. For purposes of Section 203, a “business combination” is defined broadly to include a merger,
asset sale or other transaction resulting in a financial benefit to the interested stockholder, and, subject to certain exceptions, an
“interested stockholder” is a person who, together with his or her affiliates and associates, owns (or within three years
prior, did own) 15% or more of the corporation’s voting stock.

 

Classified Board of Directors; Appointment of Directors
to Fill Vacancies; Removal of Directors for Cause. Our Restated Certificate of Incorporation provides that our board of directors
will be divided into three classes as nearly equal in number as possible. Each year the stockholders will elect the members of one of
the three classes to a three-year term of office. All directors elected to our classified board of directors will serve until the election
and qualification of their respective successors or their earlier resignation or removal. The board of directors is authorized to create
new directorships and to fill any positions so created and is permitted to specify the class to which any new position is assigned. The
person filling any of these positions would serve for the term applicable to that class. The board of directors (or its remaining members,
even if less than a quorum) is also empowered to fill vacancies on the board of directors occurring for any reason for the remainder of
the term of the class of directors in which the vacancy occurred. Members of the board of directors may only be removed for cause and
only by the affirmative vote of holders of at least 80% of our outstanding voting stock. These provisions are likely to increase the time
required for stockholders to change the composition of the board of directors. For example, in general, at least two annual meetings will
be necessary for stockholders to effect a change in a majority of the members of the board of directors.

 

Authorization of Blank Check Preferred Stock. Our
Restated Certificate of Incorporation provides that our board of directors is authorized to issue, without stockholder approval, blank
check preferred stock. Blank check preferred stock can operate as a defensive measure known as a “poison pill” by diluting
the stock ownership of a potential hostile acquirer to prevent an acquisition that is not approved by our board of directors.

 

Advance Notice Provisions for Stockholder Proposals
and Stockholder Nominations of Directors. Our Restated Bylaws provide that, for nominations to the board of directors or for other
business to be properly brought by a stockholder before a meeting of stockholders, the stockholder must first have given timely notice
of the proposal in writing to our Secretary. For an annual meeting, a stockholder’s notice generally must be delivered not less
than 90 days nor more than 120 days prior to the anniversary of the mailing date of the proxy statement for the previous year’s
annual meeting. For a special meeting, the notice must generally be delivered no less than 60 days nor more than 90 days prior to the
special meeting or ten days following the day on which public announcement of the meeting is first made. Detailed requirements as to the
form of the notice and information required in the notice are specified in our Restated Bylaws. If it is determined that business was
not properly brought before a meeting in accordance with our bylaw provisions, this business will not be conducted at the meeting.

 

Special Meetings of Stockholders. Special meetings
of the stockholders may be called only by our board of directors pursuant to a resolution adopted by a majority of the total number of
directors.

 

No Stockholder Action by Written Consent. Our
Restated Certificate of Incorporation does not permit our stockholders to act by written consent. As a result, any action to be affected
by our stockholders must be affected at a duly called annual or special meeting of the stockholders.

 

Super-Majority Stockholder Vote required for Certain
Actions. The Delaware General Corporation Law provides generally that the affirmative vote of a majority of the shares entitled to
vote on any matter is required to amend a corporation’s certificate of incorporation or bylaws, unless the corporation’s certificate
of incorporation or bylaws, as the case may be, requires a greater percentage. Our Restated Certificate of Incorporation requires the
affirmative vote of the holders of at least 80% of our outstanding voting stock to amend or repeal any of the provisions discussed in
this section entitled “Effect of Anti-Takeover Provisions of Our Restated Certificate of Incorporation, Our Restated Bylaws and
Delaware Law” or to reduce the number of authorized shares of common stock or preferred stock. This 80% stockholder vote would be
in addition to any separate class vote that might in the future be required pursuant to the terms of any preferred stock that might then
be outstanding. An 80% vote is also required for any amendment to, or repeal of, our Restated Bylaws by the stockholders. Our Restated
Bylaws may be amended or repealed by a simple majority vote of the board of directors.

 

Potential Effects of Authorized but Unissued Stock

 

We have shares of common stock and preferred stock
available for future issuance without stockholder approval. We may utilize these additional shares for a variety of corporate purposes,
including future public offerings to raise additional capital, to facilitate corporate acquisitions or payment as a dividend on the capital
stock.

 

The existence of unissued and unreserved common stock
and preferred stock may enable our board of directors to issue shares to persons friendly to current management or to issue preferred
stock with terms that could render more difficult or discourage a third-party attempt to obtain control of us by means of a merger, tender
offer, proxy contest or otherwise, thereby protecting the continuity of our management. In addition, the board of directors has the discretion
to determine designations, rights, preferences, privileges and restrictions, including voting rights, dividend rights, conversion rights,
redemption privileges and liquidation preferences of each series of preferred stock, all to the fullest extent permissible under the Delaware
General Corporation Law and subject to any limitations set forth in our certificate of incorporation. The purpose of authorizing the board
of directors to issue preferred stock and to determine the rights and preferences applicable to such preferred stock is to eliminate delays
associated with a stockholder vote on specific issuances. The issuance of preferred stock, while providing desirable flexibility in connection
with possible financings, acquisitions and other corporate purposes, could have the effect of making it more difficult for a third-party
to acquire, or could discourage a third-party from acquiring, a majority of our outstanding voting stock.
