WARRANT AGREEMENT

Exhibit 4.4

WARRANT AGREEMENT

This Warrant Agreement (this “Agreement”) made as of [_____], 2017 between Constellation Alpha Capital Corp., a British Virgin Islands company, with offices at Emerald View, Suite ###-###-#### Vista Parkway West Palm Beach, FL 33411 (“Company”), and Continental Stock Transfer& Trust Company, a New York corporation, with offices at 17 Battery Place, New York, New York 10004 (“Warrant Agent”).

WHEREAS, the Company has received binding commitments (“Subscription Agreements”) from Centripetal, LLC (the “Sponsor”) and from Cowen Investments LLC (“Cowen”) to purchase up to an aggregate of 417,500 units, each unit (“Unit”) comprised of one Ordinary Share of the Company, no par value (“Ordinary Share”), one right to receive one-tenth (1/10) of one Ordinary Share (“Right”) and one warrant to purchase one-half of one Ordinary Share for $11.50 per whole share, subject to adjustment as described herein, and in connection therewith, will issue and deliver up to an aggregate of 417,500 warrants (“Private Warrants”) upon consummation of such private placement (the “Private Offering”); and

WHEREAS, the Company is engaged in a public offering (“Public Offering”) of Units and, in connection therewith, will issue and deliver up to 14,375,000 warrants (“Public Warrants”) to the public investors and, together with the Private Warrants, the “Warrants”); and

WHEREAS, in order to finance the Company’s transaction costs in connection with an intended initial Business Combination (defined below), the Sponsor or an affiliate of the Sponsor or certain of the Company’s executive officers and directors may loan to the Company funds as may be required, of which up to $1,500,000 of such loans may be convertible into up to an additional 1,500,000 Units; and

WHEREAS, the Company has filed with the Securities and Exchange Commission (the “SEC”) a Registration Statement on Form S-1, No. 333-[____] (“Registration Statement”), for the registration, under the Securities Act of 1933, as amended (“Act”), of, among other securities, the Public Warrants; and

WHEREAS, the Company desires the Warrant Agent to act on behalf of the Company, and the Warrant Agent is willing to so act, in connection with the issuance, registration, transfer, exchange, redemption and exercise of the Warrants; and

WHEREAS, the Company desires to provide for the form and provisions of the Warrants, the terms upon which they shall be issued and exercised, and the respective rights, limitation of rights, and immunities of the Company, the Warrant Agent, and the holders of the Warrants; and

WHEREAS, all acts and things have been done and performed which are necessary to make the Warrants, when executed on behalf of the Company and countersigned by or on behalf of the Warrant Agent, as provided herein, the valid, binding and legal obligations of the Company, and to authorize the execution and delivery of this Agreement.

NOW, THEREFORE, in consideration of the mutual agreements herein contained, the parties hereto agree as follows:

1. Appointment of Warrant Agent. The Company hereby appoints the Warrant Agent to act as agent for the Company for the Warrants, and the Warrant Agent hereby accepts such appointment and agrees to perform the same in accordance with the terms and conditions set forth in this Agreement.

2. Warrants.

2.1. Form of Warrant. Each Warrant shall initially be issued in registered form only. Physical certificates, if any, shall be in substantially the form of Exhibit A hereto, the provisions of which are incorporated herein and shall be signed by the Chairman of the Board and Chief Executive Officer of the Company and shall bear a facsimile of the Company’s seal. In the event the person whose facsimile signature has been placed upon any Warrant shall have ceased to serve in the capacity in which such person signed the Warrant before such Warrant is issued, it may be issued with the same effect as if he or she had not ceased to be such at the date of issuance.

2.2. Uncertificated Warrants. Notwithstanding anything herein to the contrary, any Warrant, or portion thereof, may be issued as part of, and be represented by, a Unit or a Private Unit, and any Warrant may be issued in uncertificated or book-entry form through the Warrant Agent and/or the facilities of The Depository Trust Company (the “Depository”) or other book-entry depositary system, in each case as determined by the Board of Directors of the Company or by an authorized committee thereof. Any Warrant so issued shall have the same terms, force and effect as a certificated Warrant that has been duly countersigned by the Warrant Agent in accordance with the terms of this Agreement.

2.3. Effect of Countersignature. Except with respect to uncertificated Warrants as described in Section 2.2 above, unless and until countersigned by the Warrant Agent pursuant to this Agreement, a Warrant shall be invalid and of no effect and may not be exercised by the holder thereof.

2.4. Registration.

2.4.1. Warrant Register. The Warrant Agent shall maintain books (“Warrant Register”) for the registration of original issuance and the registration of transfer of the Warrants. Upon the initial issuance of the Warrants in book-entry form, the Warrant Agent shall issue and register the Warrants in the names of the respective holders thereof in such denominations and otherwise in accordance with instructions delivered to the Warrant Agent by the Company.

2.4.2. Ownership of beneficial interests in the Public Warrants shall be shown on, and the transfer of such ownership shall be effected through, records maintained by institutions that have accounts with the Depository (such institution, with respect to a Warrant in its account, a “Participant”). If the Depository subsequently ceases to make its book-entry settlement system available for the Public Warrants, the Company may instruct the Warrant Agent regarding making other arrangements for book-entry settlement. In the event that the Public Warrants are not eligible for, or it is no longer necessary to have the Public Warrants available in, book-entry form, the Warrant Agent shall provide written instructions to the Depository to deliver to the Warrant Agent for cancellation each book-entry Public Warrant, and the Company shall instruct the Warrant Agent to deliver to the Depository definitive certificates in physical form evidencing such Warrants which shall be in the form annexed hereto as Exhibit A. 

2.4.3. Registered Holder. Prior to due presentment for registration of transfer of any Warrant, the Company and the Warrant Agent may deem and treat the person in whose name such Warrant shall be registered upon the Warrant Register (“registered holder”) as the absolute owner of such Warrant and of each Warrant represented thereby (notwithstanding any notation of ownership or other writing on the Warrant Certificate made by anyone other than the Company or the Warrant Agent), for the purpose of any exercise thereof, and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary.

2.5. Detachability of Warrants. The securities comprising the Units will not be separately tradeable until the fifty second (52^nd) day after the date hereof unless Cowen and Company, LLC (the “Representative”) informs the Company of its decision to allow earlier separate trading, but in no event will separate trading of the securities comprising the Units begin until (i) the Company files a Current Report on Form 8-K with the SEC which includes an audited balance sheet reflecting the receipt by the Company of the gross proceeds of the Public Offering including the proceeds received by the Company from the exercise of the over-allotment option, if the over-allotment option is exercised on the date hereof, and (ii) the Company issues a press release and files a Current Report on Form 8-K with the SEC announcing when such separate trading shall begin.

2.6. Private Warrant Attributes. The Private Warrants will be identical to the Public Warrants but they (i) will be exercisable either for cash or on a cashless basis at the holder’s option pursuant to Section 3.3.1(c), (ii) will not be redeemable by the Company, in either case as long as such warrants are held by the initial purchasers or their affiliates and permitted transferees (as provided below), (iii) will be subject to the transfer restrictions set forth below and (iv) may be subject to the limitations on exercise set forth in Section 3.3.2 . The provisions of this Section 2.6 may not be modified, amended or deleted without the prior written consent of the Representative. Prior to the date immediately following the consummation by the Company of a Business Combination (as defined below), the Private Warrants may only be transferred by the holders thereof:

3. Terms and Exercise of Warrants

3.1. Warrant Price. Each Warrant shall, when countersigned by the Warrant Agent (if in physical), entitle the registered holder thereof, subject to the provisions of such Warrant and of this Agreement, to purchase from the Company the number of Ordinary Shares stated therein, at the price of $11.50 per whole share, subject to the adjustments provided in Section 4 hereof and in the last sentence of this Section 3.1. The term “Warrant Price” as used in this Agreement refers to the price per share at which Ordinary Shares may be purchased at the time a Warrant is exercised. The Company in its sole discretion may lower the Warrant Price at any time prior to the Expiration Date (as defined below) for a period of not less than 20 business days; provided, however, that the Company shall provide at least 10 business days prior written notice of such reduction to registered holders of the Warrants; provided, further, however, that any such reduction shall be applied consistently to all of the Warrants.

3.2. Duration of Warrants. A Warrant may be exercised only during the period (“Exercise Period”) commencing on the later of the consummation by the Company of a share exchange, share reconstruction and amalgamation with, purchase of all or substantially all of the assets of, contractual arrangements with, or any other similar business combination with one or more businesses or entities (“Business Combination”) (as described more fully in the Registration Statement) and 12 months from the effective date of the Registration Statement of the Public Offering, and terminating at 5:00 p.m., New York City time on the earlier to occur of (i) five years from the consummation of a Business Combination (ii) the liquidation of the Company, and (iii) the Redemption Date as provided in Section 6.2 of this Agreement (“Expiration Date”); provided, however, that the exercise of any Warrant shall be subject to the satisfaction of any applicable conditions, as set forth in Section 7.4 below; provided further, that for as long as any of the Private Warrants are held by Cowen or its designees or affiliates, such Private Warrants may not be exercised after five years from the effective date of the Registration Statement. Except with respect to the right to receive the Redemption Price in the event of a redemption (as set forth in Section 6 hereunder), each Warrant not exercised on or before the Expiration Date shall become void, and all rights thereunder and all rights in respect thereof under this Agreement shall cease at the close of business on the Expiration Date. The Company in its sole discretion may extend the duration of the Warrants by delaying the Expiration Date; provided, however, that the Company will provide written notice to registered holders of the Warrants of such extension of not less than 20 days.

3.3. Exercise of Warrants.

3.3.1. Payment. Subject to the provisions of the Warrant and this Agreement, a Warrant, when countersigned by the Warrant Agent (if applicable), may be exercised by the registered holder thereof by delivering to the Warrant Agent at its corporate trust department (i) the Warrant Certificate evidencing the Warrants to be exercised, or, in the case of a Warrant represented by a book-entry, the Warrants to be exercised on the records of the Depository to an account of the Warrant Agent at the Depository designated for such purposes in writing by the Warrant Agent to the Depository from time to time, (ii) an election to purchase any Ordinary Shares pursuant to the exercise of a Warrant, properly completed and executed by the Registered Holder on the reverse of the Warrant Certificate or, in the case of a Book-Entry Warrant, properly delivered by the Depository participant in accordance with the Depositary’s procedures, and (iii) by paying in full the Warrant Price for each full Ordinary Share as to which the Warrant is exercised and any and all applicable taxes due in connection with the exercise of the Warrant, the exchange of the Warrant for the Ordinary Shares and the issuance of such Ordinary Shares, as follows:

(a) in lawful money of the United States, in good certified check or good bank draft payable to the order of the Warrant Agent;

(b) in the event of redemption pursuant to Section 6 hereof in which the Company’s management has elected to require all holders of Warrants to exercise such Warrants on a “cashless basis,” by surrendering the Warrants for that number of Ordinary Shares equal to the quotient obtained by dividing (x) the product of the number of Ordinary Shares underlying the Warrants, multiplied by the difference between the Warrant Price and the “Fair Market Value” (defined below) by (y) the Fair Market Value, provided, however, that no cashless exercise shall be permitted unless the Fair Market Value is higher than the exercise price. Solely for purposes of this Section 3.3.1(b), the “Fair Market Value” shall mean the average reported last sale price of the Ordinary Shares for the 10 trading days ending on the third trading day prior to the date on which the notice of redemption is sent to holders of Warrant pursuant to Section 6 hereof; or

(c) with respect to any Private Warrants, so long as such Private Warrants are held by the initial purchasers or their affiliates and permitted transferees (as prescribed in Section 5.6 hereof), by surrendering such Private Warrants for that number of Ordinary Shares equal to the quotient obtained by dividing (x) the product of the number of Ordinary Shares underlying the Warrants, multiplied by the difference between the exercise price of the Warrants and the “Fair Market Value” by (y) the Fair Market Value; provided, however, that no cashless exercise shall be permitted unless the Fair Market Value is higher than the exercise price. Solely for purposes of this Section 3.3.1(c), the “Fair Market Value” shall mean the average reported last sale price of the Ordinary Shares for the 10 trading days ending on the day prior to the Company’s receipt of the applicable exercise notice; or

(d) in the event the registration statement required by Section 7.4 hereof is not then effective and current, then during the period beginning on the 91^st day after the closing of the Business Combination and ending upon the effectiveness of such registration statement, and during any other period after such date of effectiveness when the Company shall fail to have maintained an effective registration statement covering the Ordinary Shares issuable upon exercise of the Warrants, by surrendering such Warrants for that number of Ordinary Shares equal to the quotient obtained by dividing (x) the product of the number of Ordinary Shares underlying the Warrants, multiplied by the difference between the exercise price of the Warrants and the “Fair Market Value” by (y) the Fair Market Value; provided, however, that no cashless exercise shall be permitted unless the Fair Market Value is higher than the exercise price. Solely for purposes of this Section 3.3.1(d), the “Fair Market Value” shall mean the average reported last sale price of the Ordinary Shares for the 10 trading days ending on the day prior to the date of exercise.

3.3.2. Issuance of Ordinary Shares. As soon as practicable after the exercise of any Warrant and the clearance of the funds in payment of the Warrant Price (if any), the Company shall issue to the registered holder of such Warrant a book-entry position or certificate or certificates for the number of full Ordinary Shares to which he, she or it is entitled, registered in such name or names as may be directed by him, her or it, and if such Warrant shall not have been exercised in full, a new book-entry position or countersigned Warrant (as the case may be) for the number of shares as to which such Warrant shall not have been exercised. Subject to Section 4.7 of this Agreement, a registered holder of Warrants may exercise its Warrants only for a whole number of Ordinary Shares (i.e., only an even number of Warrants may be exercised at any given time by a registered holder). Notwithstanding the foregoing, in no event will the Company be required to net cash settle the Warrant exercise. The Company shall not be obligated to deliver any Ordinary Shares pursuant to the exercise of a Warrant and shall have no obligation to settle such Warrant exercise unless a registration statement under the Act with respect to the Ordinary Shares underlying the Public Warrants is then effective and a prospectus relating thereto is current, subject to the Company’s satisfying its obligations under Section 7.4. Warrants may not be exercised by, or securities issued to, any registered holder in any state in which such exercise would be unlawful. No Warrant shall be exercisable and the Company shall not be obligated to issue Ordinary Shares upon exercise of a Warrant unless the Ordinary Shares issuable upon such Warrant exercise have been registered, qualified or deemed to be exempt under the securities laws of the state of residence of the registered holder of the Warrants. In the event that the conditions in the immediately preceding three sentences are not satisfied with respect to a Warrant, the holder of such Warrant shall not be entitled to exercise such Warrant and such Warrant may have no value and expire worthless, in which case the purchaser of a Unit containing such Public Warrants shall have paid the full purchase price for the Unit solely for the Ordinary Shares underlying such Unit. If, by reason of any exercise of warrants on a “cashless basis”, the holder of any Warrant would be entitled, upon the exercise of such Warrant, to receive a fractional interest in a share, the Company shall round down to the nearest whole number, the number of shares to be issued to such holder.

3.3.3. Valid Issuance. All Ordinary Shares issued upon the proper exercise of a Warrant in conformity with this Agreement shall be validly issued, fully paid and nonassessable.

3.3.4. Date of Issuance. Each person in whose name any book-entry position or certificate, as applicable, for Ordinary Shares is issued shall for all purposes be deemed to have become the holder of record of such shares on the date on which the Warrant, or book-entry position representing such Warrant, was surrendered and payment of the Warrant Price was made, irrespective of the date of delivery of such certificate in the case of a certificated Warrant, except that, if the date of such surrender and payment is a date when the share transfer books of the Company or book-entry system of the Warrant Agent are closed, such person shall be deemed to have become the holder of such shares at the close of business on the next succeeding date on which the share transfer books or book-entry system are open.

3.3.5. Maximum Percentage.  A holder of a Warrant may notify the Company in writing in the event it elects to be subject to the provisions contained in this subsection 3.3.5; however, no holder of a Warrant shall be subject to this subsection 3.3.5 unless he, she or it makes such election. If the election is made by a holder, the Warrant Agent shall not affect the exercise of the holder’s Warrant, and such holder shall not have the right to exercise such Warrant, to the extent that after giving effect to such exercise, such person (together with such person’s affiliates), to the Warrant Agent’s actual knowledge, would beneficially own in excess of 9.8% (the “Maximum Percentage”) of the Ordinary Shares outstanding immediately after giving effect to such exercise.  For purposes of the foregoing sentence, the aggregate number of Ordinary Shares beneficially owned by such person and its affiliates shall include the number of Ordinary Shares issuable upon exercise of the Warrant with respect to which the determination of such sentence is being made, but shall exclude Ordinary Shares that would be issuable upon (x) exercise of the remaining, unexercised portion of the Warrant beneficially owned by such person and its affiliates and (y) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company beneficially owned by such person and its affiliates (including, without limitation, any convertible notes or convertible preferred shares or warrants) subject to a limitation on conversion or exercise analogous to the limitation contained herein. Except as set forth in the preceding sentence, for purposes of this paragraph, beneficial ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).  For purposes of the Warrant, in determining the number of outstanding Ordinary Shares, the holder may rely on the number of outstanding Ordinary Shares as reflected in (1) the Company’s most recent annual report on Form 10-K, quarterly report on Form 10-Q, current report on Form 8-K or other public filing with the Commission as the case may be, (2) a more recent public announcement by the Company or (3) any other notice by the Company or the Company’s transfer agent setting forth the number of Ordinary Shares outstanding.  For any reason at any time, upon the written request of the holder of the Warrant, the Company shall, within two (2) business days, confirm orally and in writing to such holder the number of Ordinary Shares then outstanding.  In any case, the number of outstanding Ordinary Shares shall be determined after giving effect to the conversion or exercise of equity securities of the Company by the holder and its affiliates since the date as of which such number of outstanding Ordinary Shares was reported.  By written notice to the Company, the holder of a Warrant may from time to time increase or decrease the Maximum Percentage applicable to such holder to any other percentage specified in such notice; provided, however, that any such increase shall not be effective until the sixty-first (61st) day after such notice is delivered to the Company.

4. Adjustments.

4.1. Share Dividends - Split Ups. If after the date hereof, the number of outstanding Ordinary Shares is increased by a share dividend payable in Ordinary Shares, or by a split up of the Ordinary Shares, or other similar event, then, on the effective date of such share dividend, split up or similar event, the number of Ordinary Shares issuable on exercise of each Warrant shall be increased in proportion to such increase in outstanding Ordinary Shares. A rights offering to all holders of the Ordinary Shares entitling holders to purchase Ordinary Shares at a price less than the “Fair Market Value” (as defined below) shall be deemed a share dividend of a number of Ordinary Shares equal to the product of (i) the number of Ordinary Shares actually sold in such rights offering (or issuable under any other equity securities sold in such rights offering that are convertible into or exercisable for the Ordinary Shares) multiplied by (ii) one (1) minus the quotient of (x) the price per Ordinary Share paid in such rights offering divided by (y) the Fair Market Value. For purposes of this subsection 4.1, (i) if the rights offering is for securities convertible into or exercisable for Ordinary Shares, in determining the price payable for the Ordinary Shares, there shall be taken into account any consideration received for such rights, as well as any additional amount payable upon exercise or conversion and (ii) “Fair Market Value” means the volume weighted average price of the Ordinary Shares as reported during the ten (10) trading day period ending on the trading day prior to the first date on which the Ordinary Shares trade on the applicable exchange or in the applicable market, regular way, without the right to receive such rights.

4.2. Aggregation of Shares. If after the date hereof, the number of outstanding Ordinary Shares is decreased by a consolidation, combination, reverse share split or reclassification of the Ordinary Shares or other similar event, then, on the effective date of such consolidation, combination, reverse share split, reclassification or similar event, the number of Ordinary Shares issuable on exercise of each Warrant shall be decreased in proportion to such decrease in outstanding Ordinary Shares.

4.3. Extraordinary Dividends.  If the Company, at any time while the Warrants are outstanding and unexpired, shall pay a dividend or make a distribution in cash, securities or other assets to the holders of the Ordinary Shares on account of such Ordinary Shares (or other shares of the Company’s share capital into which the Warrants are convertible), other than (a) as described in subsection 4.1 above, (b) Ordinary Cash Dividends (as defined below), (c) to satisfy the conversion rights of the holders of the Ordinary Shares in connection with a proposed initial Business Combination, (d) to satisfy the redemption rights of the holders of the Ordinary Shares in connection with a vote to amend the Company’s amended and restated memorandum and articles of association pursuant to Regulation 23.11 thereof, (e) as a result of the repurchase of Ordinary Shares by the Company in connection with an initial Business Combination or as otherwise permitted by the Investment Management Trust Agreement between the Company and the Warrant Agent dated of even date herewith or (f) in connection with the Company’s liquidation and the distribution of its assets upon its failure to consummate a Business Combination (any such non-excluded event being referred to herein as an “Extraordinary Dividend”), then the Warrant Price shall be decreased, effective immediately after the effective date of such Extraordinary Dividend, by the amount of cash and the fair market value (as determined by the Company’s board of directors, in good faith) of any securities or other assets paid on each Ordinary Share in respect of such Extraordinary Dividend. For purposes of this subsection 4.3, “Ordinary Cash Dividends” means any cash dividend or cash distribution which, when combined on a per share basis with the per share amounts of all other cash dividends and cash distributions paid on the Ordinary Shares during the 365-day period ending on the date of declaration of such dividend or distribution (as adjusted to appropriately reflect any of the events referred to in other subsections of this Section 4 and excluding cash dividends or cash distributions that resulted in an adjustment to the Warrant Price or to the number of Ordinary Shares issuable on exercise of each Warrant) does not exceed $0.50 (being 5% of the offering price of the Units in the Offering). 

4.4. Adjustments in Exercise Price. Whenever the number of Ordinary Shares purchasable upon the exercise of the Warrants is adjusted, as provided in Section 4.1 and 4.2 above, the Warrant Price shall be adjusted (to the nearest cent) by multiplying such Warrant Price immediately prior to such adjustment by a fraction (x) the numerator of which shall be the number of Ordinary Shares purchasable upon the exercise of the Warrants immediately prior to such adjustment, and (y) the denominator of which shall be the number of Ordinary Shares so purchasable immediately thereafter.

4.5. Replacement of Securities upon Reorganization, etc. In case of any reclassification or reorganization of the outstanding Ordinary Shares (other than a change covered by Section 4.1 or 4.2 hereof or that solely affects the par value of such Ordinary Shares), or in the case of any merger or consolidation of the Company with or into another corporation (other than a consolidation or merger in which the Company is the continuing corporation and that does not result in any reclassification or reorganization of the outstanding Ordinary Shares), or in the case of any sale or conveyance to another corporation or entity of the assets or other property of the Company as an entirety or substantially as an entirety in connection with which the Company is dissolved, the Warrant holders shall thereafter have the right to purchase and receive, upon the basis and upon the terms and conditions specified in the Warrants and in lieu of the Ordinary Shares of the Company immediately theretofore purchasable and receivable upon the exercise of the rights represented thereby, the kind and amount of shares of stock or other securities or property (including cash) receivable upon such reclassification, reorganization, merger or consolidation, or upon a dissolution following any such sale or transfer, that the Warrant holder would have received if such Warrant holder had exercised his, her or its Warrant(s) immediately prior to such event; and if any reclassification also results in a change in Ordinary Shares covered by Section 4.1 or 4.2, then such adjustment shall be made pursuant to Sections 4.1, 4.2, 4.4 and this Section 4.5. The provisions of this Section 4.5 shall similarly apply to successive reclassifications, reorganizations, mergers or consolidations, sales or other transfers.

4.6. Notices of Changes in Warrant. Upon every adjustment of the Warrant Price or the number of shares issuable upon exercise of a Warrant, the Company shall give written notice thereof to the Warrant Agent, which notice shall state the Warrant Price resulting from such adjustment and the increase or decrease, if any, in the number of shares purchasable at such price upon the exercise of a Warrant, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. Upon the occurrence of any event specified in Sections 4.1, 4.2, 4.3, 4.4 or 4.5, then, in any such event, the Company shall give written notice to each Warrant holder, at the last address set forth for such holder in the warrant register, of the record date or the effective date of the event. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such event.

4.7. No Fractional Shares. Notwithstanding any provision contained in this Agreement to the contrary, the Company shall not issue fractional shares upon exercise of Warrants. If, by reason of any adjustment made pursuant to this Section 4, the holder of any Warrant would be entitled, upon the exercise of such Warrant, to receive a fractional interest in a share, the Company shall, upon such exercise, round down to the nearest whole number the number of the Ordinary Shares to be issued to the Warrant holder.

4.8. Form of Warrant. The form of Warrant need not be changed because of any adjustment pursuant to this Section 4, and Warrants issued after such adjustment may state the same Warrant Price and the same number of shares as is stated in the Warrants initially issued pursuant to this Agreement; provided, however, that the Company may at any time in its sole discretion make any change in the form of Warrant that the Company may deem appropriate and that does not affect the substance thereof, and any Warrant thereafter issued or countersigned, whether in exchange or substitution for an outstanding Warrant or otherwise, may be in the form as so changed.

4.9. Other Events. In case any event shall occur affecting the Company as to which none of the provisions of preceding subsections of this Section 4 are strictly applicable, but which would require an adjustment to the terms of the Warrants in order to (i) avoid an adverse impact on the Warrants and (ii) effectuate the intent and purpose of this Section 4, then, in each such case, the Company shall appoint a firm of independent public accountants, investment banking or other appraisal firm of recognized national standing, which shall give its opinion as to whether or not any adjustment to the rights represented by the Warrants is necessary to effectuate the intent and purpose of this Section 4 and, if such firm determines that an adjustment is necessary, the terms of such adjustment; provided, however, that under no circumstances shall the Warrants be adjusted pursuant to this Section 4 as a result of any issuance of securities in connection with the Business Combination. The Company shall adjust the terms of the Warrants in a manner that is consistent with any adjustment recommended in such opinion.  

5. Transfer and Exchange of Warrants.

5.1. Registration of Transfer. The Warrant Agent shall register the transfer, from time to time, of any outstanding Warrant upon the Warrant Register, upon surrender of such Warrant for transfer, properly endorsed with signatures properly guaranteed and accompanied by appropriate instructions for transfer. Upon any such transfer, a new Warrant representing an equal aggregate number of Warrants shall be issued and the old Warrant shall be cancelled by the Warrant Agent. The Warrants so cancelled shall be delivered by the Warrant Agent to the Company from time to time upon request.

5.2. Procedure for Surrender of Warrants. Warrants may be surrendered to the Warrant Agent, together with a written request for exchange or transfer, and thereupon the Warrant Agent shall issue in exchange therefor one or more new Warrants as requested by the registered holder of the Warrants so surrendered, representing an equal aggregate number of Warrants; provided, however, that in the event that a Warrant surrendered for transfer bears a restrictive legend, the Warrant Agent shall not cancel such Warrant and issue new Warrants in exchange therefor until the Warrant Agent has received an opinion of counsel for the Company stating that such transfer may be made and indicating whether the new Warrants must also bear a restrictive legend.

5.3. Fractional Warrants. The Warrant Agent shall not be required to effect any registration of transfer or exchange which will result in the issuance of a warrant certificate or book-entry position for a fraction of a warrant.

5.4. Service Charges. No service charge shall be made for any exchange or registration of transfer of Warrants.

5.5. Warrant Execution and Countersignature. The Warrant Agent is hereby authorized to countersign and to deliver, in accordance with the terms of this Agreement, the Warrants required to be issued pursuant to the provisions of this Section 5, and the Company, whenever required by the Warrant Agent, will supply the Warrant Agent with Warrants duly executed on behalf of the Company for such purpose.

5.6. Private Warrants. The Warrant Agent shall not register any transfer of Private Warrants until after the consummation by the Company of a Business Combination, except for transfers made in accordance with Section 2.6 hereof, on the condition that prior to such registration for transfer, the Warrant Agent shall be presented with written documentation pursuant to which each transferee or the trustee or legal guardian for such transferee agrees to be bound by the terms of the Subscription Agreements.

6. Redemption.

6.1. Redemption. Subject to Section 6.4 hereof, not less than all of the outstanding Warrants may be redeemed, at the option of the Company, at any time while they are exercisable and prior to their expiration, at the office of the Warrant Agent, upon the notice referred to in Section 6.2, at the price of $0.01 per Warrant (“Redemption Price”), provided that the last sales price of the Ordinary Shares has been at least $18.00 per share (subject to adjustment in accordance with Section 4 hereof), on each of twenty (20) trading days within any thirty (30) trading day period (“30-Day Trading Period”) ending on the third trading day prior to the date on which notice of redemption is given and provided further that there is a current registration statement in effect with respect to the issuance of the Ordinary Shares underlying the Warrants for each day in the 30-Day Trading Period and continuing each day thereafter until the Redemption Date (defined below).

6.2. Date Fixed for, and Notice of, Redemption. In the event the Company shall elect to redeem all of the Warrants, the Company shall fix a date for the redemption (the “Redemption Date”). Notice of redemption shall be mailed by first class mail, postage prepaid, by the Company not less than 30 days prior to the Redemption Date to the registered holders of the Warrants to be redeemed at their last addresses as they shall appear on the registration books. Any notice mailed in the manner herein provided shall be conclusively presumed to have been duly given whether or not the registered holder received such notice. 

6.3. Exercise After Notice of Redemption. The Warrants may be exercised, for cash (or on a “cashless basis” in accordance with Section 3 of this Agreement) at any time after notice of redemption shall have been given by the Company pursuant to Section 6.2 hereof and prior to the Redemption Date. In the event the Company determines to require all holders of Warrants to exercise their Warrants on a “cashless basis” pursuant to Section 3.3.1(b), the notice of redemption will contain the information necessary to calculate the number of Ordinary Shares to be received upon exercise of the Warrants, including the “Fair Market Value” (within the meaning of Section 3.3.1(b)) in such case. On and after the Redemption Date, the record holder of the Warrants shall have no further rights except to receive, upon surrender of the Warrants, the Redemption Price.

6.4. Exclusion of Certain Warrants. Any of the Private Warrants shall not be redeemable by the Company as long as such Private Warrants continue to be held by initial purchasers and affiliates or their permitted transferees (as prescribed in Section 5.6 hereof). However, once such Private Warrants are no longer held by the initial purchasers or their affiliates or permitted transferees, such Private Warrants shall then be redeemable by the Company pursuant to Section 6 hereof. The provisions of this Section 6.4 may not be modified, amended or deleted without the prior written consent of the Representative.

7. Other Provisions Relating to Rights of Holders of Warrants.

7.1. No Rights as Shareholder. A Warrant does not entitle the registered holder thereof to any of the rights of a shareholder of the Company, including, without limitation, the right to receive dividends, or other distributions, exercise any preemptive rights to vote or to consent or to receive notice as shareholders in respect of the meetings of shareholders or the election of directors of the Company or any other matter.

7.2. Lost, Stolen, Mutilated, or Destroyed Warrants. If any Warrant is lost, stolen, mutilated, or destroyed, the Company and the Warrant Agent may on such terms as to indemnity or otherwise as they may in their discretion impose (which shall, in the case of a mutilated Warrant, include the surrender thereof), issue a new Warrant of like denomination, tenor, and date as the Warrant so lost, stolen, mutilated, or destroyed. Any such new Warrant shall constitute a substitute contractual obligation of the Company, whether or not the allegedly lost, stolen, mutilated, or destroyed Warrant shall be at any time enforceable by anyone.

7.3. Reservation of Ordinary Shares. The Company shall at all times reserve and keep available a number of its authorized but unissued Ordinary Shares that will be sufficient to permit the exercise in full of all outstanding Warrants issued pursuant to this Agreement.

7.4. Registration of Ordinary Shares. The Company agrees that as soon as practicable after the closing of a Business Combination, it shall use its best efforts to file with the SEC a new registration statement, for the registration, under the Act, of the Ordinary Shares issuable upon exercise of the Warrants, and it shall use its best efforts to take such action as is necessary to qualify for sale, in those states in which the Warrants were initially offered by the Company, the Ordinary Shares issuable upon exercise of the Warrants. In either case, the Company will use its best efforts to cause the same to become effective and to maintain the effectiveness of such registration statement until the expiration of the Warrants in accordance with the provisions of this Agreement. In addition, the Company agrees to use its best efforts to register such securities under the blue sky laws of the states of residence of the exercising warrant holders to the extent an exemption is not available. If any such registration statement has not been declared effective by the 90-day anniversary following the closing of the Business Combination, holders of the Warrants shall have the right, during the period beginning on the 91^st day after the closing of the Business Combination and ending upon such registration statement being declared effective by the SEC, and during any other period after such date of effectiveness when the Company shall fail to have maintained an effective and current registration statement covering the Ordinary Shares issuable upon exercise of the Warrants, to exercise such Warrants on a “cashless basis” as determined in accordance with Section 3.3.1(d). In connection with the cashless exercise of the Public Warrants, the Company shall provide the Warrant Agent with an opinion of counsel for the Company (which shall be an outside law firm with securities law experience) stating that (i) the issuance of Ordinary Shares upon exercise of the Warrants on a cashless basis in accordance with this Section 7.4 is not required to be registered under the Act and (ii) the Ordinary Shares issued upon such exercise will be freely tradable under U.S. federal securities laws by anyone who is not an affiliate (as such term is defined in Rule 144 under the Act) of the Company and, accordingly, will not be required to bear a restrictive legend. For the avoidance of any doubt, unless and until all of the Warrants have been exercised on a cashless basis, the Company shall continue to be obligated to comply with its registration obligations under the first three sentences of this Section 7.4. The provisions of this Section 7.4 may not be modified, amended or deleted without the prior written consent of the Representative.

8. Concerning the Warrant Agent and Other Matters.

8.1. Payment of Taxes. The Company will from time to time promptly pay all taxes and charges that may be imposed upon the Company or the Warrant Agent in respect of the issuance or delivery of Ordinary Shares upon the exercise of Warrants, but the Company shall not be obligated to pay any transfer taxes in respect of the Warrants or such shares.

8.2. Resignation, Consolidation, or Merger of Warrant Agent.

8.2.1. Appointment of Successor Warrant Agent. The Warrant Agent, or any successor to it hereafter appointed, may resign its duties and be discharged from all further duties and liabilities hereunder after giving sixty (60) days’ notice in writing to the Company. If the office of the Warrant Agent becomes vacant by resignation or incapacity to act or otherwise, the Company shall appoint in writing a successor Warrant Agent in place of the Warrant Agent. If the Company shall fail to make such appointment within a period of 30 days after it has been notified in writing of such resignation or incapacity by the Warrant Agent or by the holder of the Warrant (who shall, with such notice, submit his Warrant for inspection by the Company), then the holder of any Warrant may apply to the Supreme Court of the State of New York for the County of New York for the appointment of a successor Warrant Agent at the Company’s cost. Any successor Warrant Agent, whether appointed by the Company or by such court, shall be a corporation organized and existing under the laws of the State of New York, in good standing and having its principal office in the Borough of Manhattan, City and State of New York, and authorized under such laws to exercise corporate trust powers and subject to supervision or examination by federal or state authority. After appointment, any successor Warrant Agent shall be vested with all the authority, powers, rights, immunities, duties, and obligations of its predecessor Warrant Agent with like effect as if originally named as Warrant Agent hereunder, without any further act or deed; but if for any reason it becomes necessary or appropriate, the predecessor Warrant Agent shall execute and deliver, at the expense of the Company, an instrument transferring to such successor Warrant Agent all the authority, powers, and rights of such predecessor Warrant Agent hereunder; and upon request of any successor Warrant Agent the Company shall make, execute, acknowledge, and deliver any and all instruments in writing for more fully and effectually vesting in and confirming to such successor Warrant Agent all such authority, powers, rights, immunities, duties, and obligations.

8.2.2. Notice of Successor Warrant Agent. In the event a successor Warrant Agent shall be appointed, the Company shall give notice thereof to the predecessor Warrant Agent and the transfer agent for the Ordinary Shares not later than the effective date of any such appointment.

8.2.3. Merger or Consolidation of Warrant Agent. Any corporation into which the Warrant Agent may be merged or with which it may be consolidated or any corporation resulting from any merger or consolidation to which the Warrant Agent shall be a party shall be the successor Warrant Agent under this Agreement without any further act.

8.3. Fees and Expenses of Warrant Agent.

8.3.1.  Remuneration. The Company agrees to pay the Warrant Agent reasonable remuneration for its services as such Warrant Agent hereunder and will reimburse the Warrant Agent upon demand for all expenditures that the Warrant Agent may reasonably incur in the execution of its duties hereunder.

8.3.2.  Further Assurances. The Company agrees to perform, execute, acknowledge, and deliver or cause to be performed, executed, acknowledged, and delivered all such further and other acts, instruments, and assurances as may reasonably be required by the Warrant Agent for the carrying out or performing of the provisions of this Agreement.

8.4. Liability of Warrant Agent.

8.4.1. Reliance on Company Statement. Whenever in the performance of its duties under this Agreement, the Warrant Agent shall deem it necessary or desirable that any fact or matter be proved or established by the Company prior to taking or suffering any action hereunder, such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively proved and established by a statement signed by the Chief Executive Officer or Chairman of the Board of the Company and delivered to the Warrant Agent. The Warrant Agent may rely upon such statement for any action taken or suffered in good faith by it pursuant to the provisions of this Agreement.

8.4.2. Indemnity. The Warrant Agent shall be liable hereunder only for its own gross negligence, willful misconduct or bad faith. The Company agrees to indemnify the Warrant Agent and save it harmless against any and all liabilities, including judgments, costs and reasonable counsel fees, for anything done or omitted by the Warrant Agent in the execution of this Agreement except as a result of the Warrant Agent’s gross negligence, willful misconduct, or bad faith.

8.4.3. Exclusions. The Warrant Agent shall have no responsibility with respect to the validity of this Agreement or with respect to the validity or execution of any Warrant (except its countersignature thereof); nor shall it be responsible for any breach by the Company of any covenant or condition contained in this Agreement or in any Warrant; nor shall it be responsible to make any adjustments required under the provisions of Section 4 hereof or responsible for the manner, method, or amount of any such adjustment or the ascertaining of the existence of facts that would require any such adjustment; nor shall it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of any Ordinary Shares to be issued pursuant to this Agreement or any Warrant or as to whether any Ordinary Shares will when issued be valid and fully paid and nonassessable.

8.5. Acceptance of Agency. The Warrant Agent hereby accepts the agency established by this Agreement and agrees to perform the same upon the terms and conditions herein set forth and among other things, shall account promptly to the Company with respect to Warrants exercised and concurrently account for, and pay to the Company, all moneys received by the Warrant Agent for the purchase of Ordinary Shares through the exercise of Warrants.

8.6. Waiver. The Warrant Agent hereby waives any right of set-off or any other right, title, interest or claim of any kind (“Claim”) in, or to any distribution of, the Trust Account (as defined in that certain Investment Management Trust Agreement, dated as of the date hereof, by and between the Company and the Warrant Agent as trustee thereunder) and hereby agrees not to seek recourse, reimbursement, payment or satisfaction for any Claim against the Trust Account for any reason whatsoever.
