(the “Company”), is being filed solely for the purpose of submitting certain exhibits. Accordingly, this Amendment consists only of the facing page, this explanatory note, Part II of the Registration Statement, the signature page to the Registration Statement, and Exhibit 15.1 and Exhibit 23.2. This Amendment does not modify any provisions of the prospectus that forms part of the Registration Statement and, accordingly, such prospectus has not been included herein.

    Part II

     

    Information Not Required in the Prospectus

     

    Item 20. Indemnification of Directors and Officers

     

    Under the DGCL, a Delaware corporation must indemnify its present and former directors and officers against expenses (including attorneys’ fees) actually and reasonably incurred to the extent that the officer or director has been successful on the merits or otherwise in defense of any action, suit or proceeding brought against him or her by reason of the fact that he or she is or was a director or officer of the corporation.

     

    Delaware law provides that a corporation may indemnify its present and former directors, officers, employees and agents, as well as any individual serving with another corporation in that capacity at the corporation’s request against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement of actions taken, if the individual acted in good faith and in a manner reasonably believed to be in, or not opposed to, the best interests of the corporation and, in the case of a criminal proceeding, the individual had no reasonable cause to believe the individual’s conduct was unlawful; except that no indemnification may be paid for judgments, fines and amounts paid in settlement in actions by or in the right of the corporation to procure a judgment in its favor. A corporation may not indemnify a current or former director or officer of the corporation against expenses to the extent the person is adjudged to be liable to the corporation unless a court approves the indemnity.

     

    The BlockchAIn Amended and Restated Certificate of Incorporation will provide that BlockchAIn shall indemnify, to the full extent permitted by applicable law as it presently exists or may thereafter be amended, any person who was or is a party or is threatened to be made a party to or otherwise involved any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that he or she is or was a director or officer of BlockchAIn or, while a director or officer of BlockchAIn, is or was serving at the request of BlockchAIn as a director, officer, employee, agent or trustee of another entity or enterprise, including service with respect to employee benefit plans, against all liability and loss suffered and expenses (including, without limitation, attorneys’ fees and expenses, judgments, fines, excise taxes or penalties under the Employee Retirement Income Security Act of 1974, as amended, and amounts paid or to be paid in settlement) reasonably incurred by such person. To the extent not prohibited by applicable law, expenses (including attorneys’ fees) incurred by a covered person in defending or otherwise participating in any proceeding in advance of the final disposition of such proceeding upon receipt of an undertaking by or on behalf of such person to repay such amounts advanced if it shall ultimately be determined that he or she is not entitled to be indemnified by BlockchAIn. The BlockchAIn Amended and Restated Bylaws will also contain certain indemnification provisions with respect to the directors and officers of BlockchAIn.

     

    BlockchAIn expects to enter into indemnification agreements with each of its executive officers and directors, pursuant to which BlockchAIn will agree to indemnify them to the fullest extent permitted by law. Under the indemnification agreements, BlockchAIn will agree to advance all expenses incurred by or on behalf of the independent directors in connection with any proceeding after the receipt by us of a statement requesting such advance, whether prior to or after final disposition of such proceeding.

     

    BlockchAIn will obtain standard directors and officers liability insurance under which coverage is provided (a) to BlockchAIn’s directors and officers against loss rising from claims made by reason of breach of duty or other wrongful act, and (b) to BlockchAIn with respect to payments which we may make to such officers and directors pursuant to the indemnification agreements described above or otherwise as a matter of law.

    Item 22. Undertakings

     

    1.The undersigned registrant hereby undertakes:

     

    (a)To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

     

    (i)To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

     

    (ii)To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Filing Fees Table” in the effective registration statement; and

     

    (iii)To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

     

    (b)That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

     

    (c)To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

     

    (d)That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness; provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

     

    (e)That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

     

    (i)Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

     

    (ii)Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

     

    (iii)The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

     

    (iv)Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

     

    II-4

     

     

    (f)The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Sections 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

     

    2.The undersigned registrant hereby undertakes as follows: That prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to re-offerings by persons who may be deemed underwriters, in addition to the information called for by the other Items of the applicable form.

     

    3.The registrant undertakes that every prospectus (i) that is filed pursuant to the paragraph immediately preceding, or (ii) that purports to meet the requirements of section 10(a)(3) of the Securities Act of 1933 and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

     

    4.Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.

     

    5.The undersigned registrant hereby undertakes to respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11, or 13 of this Form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

     

    6.The undersigned registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.
