PRIVATE PLACEMENT WARRANTS PURCHASE AGREEMENT

THIS PRIVATE PLACEMENT WARRANTS PURCHASE AGREEMENT, dated as of October 29, 2020 (as it may from time to time be amended, this “Agreement”), is entered into by and between Bull Horn Holdings Corp., a British Virgin Islands business company (the “Company”), Imperial Capital, LLC, a Delaware limited liability company (“Imperial”), I-Bankers Securities, Inc., a Texas corporation (“I-Bankers”) and Northland Securities, Inc., a Minnesota corporation (“Northland”, and collectively with Imperial and I-Bankers the “Purchasers”).

WHEREAS:

The Company intends to consummate an initial public offering of the Company’s units (the “Public Offering”), each unit consisting of one ordinary share of the Company, of no par value per share (each, a “Share”), and one-half of one redeemable warrant;

Each whole warrant entitles the holder to purchase one Share at an exercise price of $11.50 per Share; and

The Purchasers have agreed to purchase, at a price of $1.00 per warrant, an aggregate of 1,125,000 warrants (or 1,293,750 warrants if the over-allotment in connection with the Public Offering is exercised in full) (the “Private Placement Warrants”), each Private Placement Warrant entitling the holder to purchase one Share at an exercise price of $11.50 per Share.

NOW THEREFORE, in consideration of the mutual promises contained in this Agreement and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties to this Agreement hereby, intending legally to be bound, agree as follows:

A. Authorization of the Private Placement Warrants.  The Company has duly authorized the issuance and sale of the Private Placement Warrants to the Purchasers.

B. Purchase and Sale of the Private Placement Warrants.

Purchasers shall pay the Purchase Price by wire transfer of immediately available funds, or by such other method as may be reasonably acceptable to the Company, to the trust account (the “Trust Account”) maintained by Continental Stock Transfer & Trust Company, acting as trustee (“Continental”), on the Initial Closing Date.  On the Initial Closing Date, upon the payment by the Purchasers of the Purchase Price, the Company, at its option, shall deliver a certificate evidencing the Private Placement Warrants purchased on such date duly registered in the Purchasers’ name to the Purchaser or effect such delivery in book-entry form. It is agreed that Imperial will be responsible for purchasing 646,875 of such Private Placement Warrants, I-Bankers will be responsible for purchasing 196,875 of such Private Placement Warrants and Northland will be responsible for purchasing 281,250 of such Private Placement Warrants.

(ii)  Simultaneously with the consummation of the closing of the over-allotment option in connection with the Public Offering (the “Over-Allotment Option”) or on such earlier time and date as may be mutually agreed by the Purchasers and the Company (each such date, an “Over-allotment Closing Date,” and each Over-allotment Closing Date (if any) and the Initial Closing Date being sometimes referred to herein as a “Closing Date”), the Company shall issue and sell to the Purchasers, and the Purchasers shall purchase from the Company, an aggregate of up to 1,293,750 Private Placement Warrants at a price of $1.00 per warrant for an aggregate purchase price of up to $1,293,750 (if the over-allotment option in connection with the Public Offering is exercised in full) (the “Over-allotment Purchase Price”). Purchasers shall pay the Over-allotment Purchase Price by wire transfer of immediately available funds, or by such other method as may be reasonably acceptable to the Company, to the Trust Account maintained by Continental on the Over-allotment Closing Date.  On the Over-allotment Closing Date, upon the payment by the Purchaser of the Over-allotment Purchase Price to the Company, the Company shall, at its option, deliver a certificate evidencing the Private Placement Warrants purchased on such date duly registered in the Purchaser’s name to the Purchaser or effect such delivery in book-entry form.  It is agreed that Imperial will be responsible for purchasing 743,906 of such Private Placement Warrants, I-Bankers will be responsible for purchasing 226,406 of such Private Placement Warrants and Northland will be responsible for purchasing 323,438 of such Private Placement Warrants.

C. Terms of the Private Placement Warrants.

(i)  Each Private Placement Warrant shall have the terms set forth in a Warrant Agreement to be entered into by the Company and a warrant agent, in connection with the Public Offering (the “Warrant Agreement”).

(ii)  On the date of effectiveness (the “Effective Date”) of the registration statement relating to the Public Offering (the “Registration Statement”), the Company and the Purchasers shall enter into a registration rights agreement (the “Registration Rights Agreement”) pursuant to which the Company will grant certain registration rights to the Purchasers relating to the Private Placement Warrants and the Shares underlying the Private Placement Warrants.

(iii) The Private Placement Warrants shall be terminated upon the dissolution of the Company or in the event that the Company does not consummate an initial business combination within the time period set forth in the Company’s memorandum and articles of association, as the same may be amended from time to time.

(iv) So long as the Private Placement Warrants are held by the Purchasers or their respective designees or affiliates, the Purchasers or their respective designees or affiliates will not be permitted to exercise such Private Placement Warrants after the five year anniversary of the Effective Date in accordance with FINRA Rule 5110(f)(2)(G)(i)).

(iv) Purchasers acknowledge and agree that the Private Placement Warrants and underlying Shares and the related registration rights will be deemed compensation by the Financial Industry Regulatory Authority (“FINRA”) and will therefore, pursuant to Rule 5110(g) of the FINRA Manual, be subject to lock-up for a period of 180 days immediately following the date of effectiveness or commencement of sales in the offering contemplated by the Registration Statement, subject to certain limited exceptions to permitted transferees hereunder and in accordance with FINRA Rule 5110(g)(2). Additionally, the Private Placement Warrants and underlying Shares and the related registration rights may not be sold, transferred, assigned, pledged or hypothecated during the foregoing 180 day period following the Effective Date except to any underwriter or selected dealer participating in the offering contemplated by the Registration Statement and the respective bona fide officers or partners of the Purchasers and any such participating underwriter or selected dealer. Additionally, the Private Placement Warrants and underlying Shares and the related registration rights will not be the subject of any hedging, short sale, derivative, put or call transaction that would result in the economic disposition of such securities by any person for a period of 180 days immediately following the date of effectiveness or commencement of sales in the offering contemplated by the Registration Statement.

Section 2.  Representations and Warranties of the Company.  As a material inducement to the Purchasers to enter into this Agreement and purchase the Private Placement Warrants, the Company hereby represents and warrants to the Purchasers (which representations and warranties shall survive each Closing Date) that:

A. Incorporation and Corporate Power.  The Company is an exempted company duly incorporated, validly existing and in good standing under the laws of the Cayman Islands and is qualified to do business in every jurisdiction in which the failure to so qualify would reasonably be expected to have a material adverse effect on the financial condition, operating results or assets of the Company.  The Company possesses all requisite corporate power and authority necessary to carry out the transactions contemplated by this Agreement and the Warrant Agreement.

On the date of issuance of the Private Placement Warrants, the Shares issuable upon exercise of the Private Placement Warrants shall have been reserved for issuance. Upon issuance in accordance with, and payment pursuant to, the terms hereof and the Warrant Agreement, the Purchasers will have good title to the Private Placement Warrants and the Shares issuable upon exercise of such Private Placement Warrants, free and clear of all liens, claims and encumbrances of any kind, other than (i) transfer restrictions hereunder and under the other agreements contemplated hereby, (ii) transfer restrictions under federal and state securities laws, and (iii) liens, claims or encumbrances imposed due to the actions of the Purchasers.

Section 3.  Representations and Warranties of the Purchasers.  As a material inducement to the Company to enter into this Agreement and issue and sell the Private Placement Warrants to the Purchasers, each Purchaser (severally, but not jointly) hereby represents and warrants to the Company (which representations and warranties shall survive each Closing Date) that:

A. Organization and Requisite Authority.  The Purchaser possesses all requisite power and authority necessary to carry out the transactions contemplated by this Agreement.

B. Authorization; No Breach.

(i) This Agreement constitutes a valid and binding obligation of the Purchaser, enforceable in accordance with its terms, subject to bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other laws of general applicability relating to or affecting creditors’ rights and to general equitable principles (whether considered in a proceeding in equity or law).

3

(ii) The execution and delivery by the Purchaser of this Agreement and the fulfillment of and compliance with the terms hereof by the Purchaser does not and shall not as of each Closing Date conflict with or result in a breach by the Purchaser of the terms, conditions or provisions of any agreement, instrument, order, judgment or decree to which the Purchaser is subject.

C. Investment Representations.

(i) The Purchaser is acquiring the Private Placement Warrants and, upon exercise of the Private Placement Warrants, the Shares issuable upon such exercise (collectively, the “Securities”), for the Purchaser’s own account, for investment purposes only and not with a view towards, or for resale in connection with, any public sale or distribution thereof.

(ii) The Purchaser is an “accredited investor” as such term is defined in Rule 501(a)(3) of Regulation D under the Securities Act and the Purchaser has not experienced a disqualifying event as enumerated pursuant to Rule 506(d) of Regulation D under the Securities Act.

(iii) The Purchaser understands that the Securities are being offered and will be sold to it in reliance on specific exemptions from the registration requirements of the United States federal and state securities laws and that the Company is relying upon the truth and accuracy of, and the Purchaser’s compliance with, the representations and warranties of the Purchaser set forth herein in order to determine the availability of such exemptions and the eligibility of the Purchaser to acquire such Securities.

(iv) The Purchaser decided to enter into this Agreement not as a result of any general solicitation or general advertising within the meaning of Rule 502(c) under the Securities Act.

(v) The Purchaser has been furnished with all materials relating to the business, finances and operations of the Company and materials relating to the offer and sale of the Securities which have been requested by the Purchaser.  The Purchaser has been afforded the opportunity to ask questions of the executive officers and directors of the Company.  The Purchaser understands that its investment in the Securities involves a high degree of risk and it has sought such accounting, legal and tax advice as it has considered necessary to make an informed investment decision with respect to the acquisition of the Securities.

(vi) The Purchaser understands that no United States federal or state agency or any other government or governmental agency has passed on or made any recommendation or endorsement of the Securities or the fairness or suitability of the investment in the Securities by the Purchaser nor have such authorities passed upon or endorsed the merits of the offering of the Securities.

(vii) The Purchaser understands that: (a) the Securities have not been and are not being registered under the Securities Act or any state securities laws, and may not be offered for sale, sold, assigned or transferred unless (1) subsequently registered thereunder or (2) sold in reliance on an exemption therefrom; and (b) except as specifically set forth in the Registration Rights Agreement, neither the Company nor any other person is under any obligation to register the Securities under the Securities Act or any state securities laws or to comply with the terms and conditions of any exemption thereunder.  The Private Placement Warrants will bear a legend and appropriate “stop transfer” instructions (or an appropriate notation if the warrants are issued in book entry form) relating to the foregoing. The Purchaser further understands that the Securities and Exchange Commission (the “SEC”) has taken the position that promoters or affiliates of a blank check company and their transferees, both before and after an initial business combination, are deemed to be “underwriters” under the Securities Act when reselling the securities of a blank check company.  Based on that position, Rule 144 adopted pursuant to the Securities Act would not be available for resale transactions of the Securities until the one-year anniversary following consummation of an initial business combination despite technical compliance with the requirements of such Rule.

(viii) The Purchaser has such knowledge and experience in financial and business matters, knows of the high degree of risk associated with investments in the securities of companies in the development stage such as the Company, is capable of evaluating the merits and risks of an investment in the Securities and is able to bear the economic risk of an investment in the Securities in the amount contemplated hereunder for an indefinite period of time.  The Purchaser has adequate means of providing for its current financial needs and contingencies and will have no current or anticipated future needs for liquidity which would be jeopardized by the investment in the Securities.  The Purchaser can afford a complete loss of its investment in the Securities.
