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


 


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


 


 2.           Rights.


 


2.1.        Form
of Right. Each Right shall be issued in registered form only, shall be in substantially the form of Exhibit A hereto, the
provisions of which are incorporated herein and shall be signed by, or bear the facsimile signature of, the Chairman of the Board
and the Secretary 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 Right shall have ceased to serve in the capacity in which such person signed the Right before
such Right 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.        Effect
of Countersignature. Unless and until countersigned by the Rights Agent pursuant to this Agreement, a Right shall be invalid
and of no effect and may not be exchanged for shares of Common Stock.


 


2.3.        Registration.


 


2.3.1.          Right
Register. The Rights Agent shall maintain books (“Right Register”) for the registration of original issuance and
the registration of transfer of the Rights. Upon the initial issuance of the Rights, the Rights Agent shall issue and register
the Rights in the names of the respective holders thereof in such denominations and otherwise in accordance with instructions
delivered to the Rights Agent by the Company.


 


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


 


2.4.         Detachability
of Rights. The securities comprising the Units, including the Rights, will not be separately transferable until ten business
days following the earlier to occur of: (i) the 52nd day following the date of the Prospectus or (ii) the announcement
by Ladenburg Thalmann & Co. Inc. of its intention to allow separate earlier trading, except that in no event will the securities
comprising the Units be separately tradeable until the Company files a Current Report on Form 8-K which includes an audited balance
sheet reflecting the receipt by the Company of the gross proceeds of the Offering including the proceeds received by the Company
from the exercise of the over-allotment option, if the over-allotment option is exercised by the date thereof and the Company
issues a press release and files a Current Report on Form 8-K announcing when such separate trading shall begin.


 


3.           Terms
and Exchange of Rights


 


3.1.         Rights.
Each Right shall entitle the holder thereof to receive one-tenth of one share of Common Stock upon the happening of an Exchange
Event (defined below). No additional consideration shall be paid by a holder of Rights in order to receive his, her or its shares
of Common Stock upon an Exchange Event as the purchase price for such shares of Common Stock has been included in the purchase
price for the Units. In no event will the Company be required to net cash settle the Rights. The provisions of this Section 3.1
may not be modified, amended or deleted without the prior written consent of the Representative.


 


3.2.        Exchange
Event. An “Exchange Event” shall occur upon the Company’s consummation of an initial Business Combination
(as defined in the Company’s Amended and Restated Certificate of Incorporation).


 






    	 	2	 



     


    

 


3.3.         Exchange
of Rights.


 


3.3.1.          Issuance
of Certificates. As soon as practicable upon the occurrence of an Exchange Event, the Company shall direct holders of the
Rights to return their Rights Certificates to the Rights Agent. Upon receipt of a valid Rights Certificate, the Company shall
issue to the registered holder of such Right(s) a certificate or certificates for the number of full shares Common Stock to which
he, she or it is entitled, registered in such name or names as may be directed by him, her or it. Notwithstanding the foregoing,
or any provision contained in this Agreement to the contrary, in no event will the Company be required to net cash settle the
Rights. The Company shall not issue fractional shares upon exchange of Rights. At the time of an Exchange Event, the Company will
either instruct the Rights Agent to round up to the nearest whole share of Common Stock or otherwise inform it how fractional
shares will be addressed, in accordance with Section 155 of the Delaware General Corporation Law. Each holder of a Right will
be required to affirmatively convert his, her or its rights in order to receive the 1/10 of a share underlying each right (without
paying any additional consideration) upon consummation of the Exchange Event. Each holder of a Right will be required to indicate
his, her or its election to convert the Rights into the underlying shares as well as to return the original certificates evidencing
the Rights to the Company. 


 


3.3.2.          Valid
Issuance. All shares of Common Stock issued upon an Exchange Event in conformity with this Agreement shall be validly issued,
fully paid and nonassessable.


 


3.3.3.          Date
of Issuance. Each person in whose name any such certificate for shares of Common Stock is issued shall for all purposes be
deemed to have become the holder of record of such shares on the date of the Exchange Event, irrespective of the date of delivery
of such certificate.


 


3.3.4           Company
Not Surviving Following Exchange Event. Upon an Exchange Event in which the Company does not continue as the publicly held
reporting entity, the definitive agreement will provide for the holders of Rights to receive the same per share consideration
the holders of the shares of Common Stock will receive in such transaction, for the number of shares such holder is entitled to
pursuant to Section 3.3.1 above.


 


3.5          Duration
of Rights. If an Exchange Event does not occur within the time period set forth in the Company’s Certificate of Incorporation,
as the same may be amended from time to time, the Rights shall expire and shall be worthless.


 


4.           Transfer
and Exchange of Rights.


 


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


 


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


 


4.3.        Fractional
Rights. The Rights Agent shall not be required to effect any registration of transfer or exchange which will result in the
issuance of a Right Certificate for a fraction of a Right.


 


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


 


4.5.        Right
Execution and Countersignature. The Rights Agent is hereby authorized to countersign and to deliver, in accordance with the
terms of this Agreement, the Rights required to be issued pursuant to the provisions of this Section 4, and the Company, whenever
required by the Rights Agent, will supply the Rights Agent with Rights duly executed on behalf of the Company for such purpose.

5.           Other
Provisions Relating to Rights of Holders of Rights.


 


5.1.        No
Rights as Shareholder. Until exchange of a Right for shares of Common Stock as provided for herein, a Right 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. 


 


5.2.        Lost,
Stolen, Mutilated, or Destroyed Rights. If any Right is lost, stolen, mutilated, or destroyed, the Company and the Rights
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
Right, include the surrender thereof), issue a new Right of like denomination, tenor, and date as the Right so lost, stolen, mutilated,
or destroyed. Any such new Right shall constitute a substitute contractual obligation of the Company, whether or not the allegedly
lost, stolen, mutilated, or destroyed Right shall be at any time enforceable by anyone.


 


5.3.        Reservation
of Common Stock. The Company shall at all times reserve and keep available a number of its authorized but unissued shares
of Common Stock that will be sufficient to permit the exchange of all outstanding Rights issued pursuant to this Agreement.


 


6.           Concerning
the Rights Agent and Other Matters.


 


6.1.         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
Rights Agent in respect of the issuance or delivery of shares of Common Stock upon the exchange of Rights, but the Company shall
not be obligated to pay any transfer taxes in respect of the Rights or such shares.


 


6.2.         Resignation,
Consolidation, or Merger of Rights Agent.


 


6.2.1.         Appointment
of Successor Rights Agent. The Rights 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 Rights Agent becomes vacant by resignation or incapacity to act or otherwise, the Company shall appoint in writing
a successor Rights Agent in place of the Rights 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 Rights Agent or by the holder of the Right
(who shall, with such notice, submit his, her or its Right for inspection by the Company), then the holder of any Right may apply
to the Supreme Court of the State of New York for the County of New York for the appointment of a successor Rights Agent at the
Company’s cost. Any successor Rights 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 Rights Agent shall be vested with all the authority, powers, rights,
immunities, duties, and obligations of its predecessor Rights Agent with like effect as if originally named as Rights Agent hereunder,
without any further act or deed; but if for any reason it becomes necessary or appropriate, the predecessor Rights Agent shall
execute and deliver, at the expense of the Company, an instrument transferring to such successor Rights Agent all the authority,
powers, and rights of such predecessor Rights Agent hereunder; and upon request of any successor Rights 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 Rights Agent all such authority, powers, rights, immunities, duties, and obligations.


 


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


 


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

and Expenses of Rights Agent.

the Rights Agent upon demand for all expenditures that the Rights Agent may reasonably incur in the execution of its duties hereunder.


 


6.3.2.         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 Rights Agent for
the carrying out or performing of the provisions of this Agreement.


 


6.4.         Liability
of Rights Agent.


 


6.4.1.         Reliance
on Company Statement. Whenever in the performance of its duties under this Agreement, the Rights 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, Chief Operating Officer or Chief Financial Officer
and delivered to the Rights Agent. The Rights Agent may rely upon such statement for any action taken or suffered in good faith
by it pursuant to the provisions of this Agreement.


 


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


 


6.4.3.         Exclusions.
The Rights Agent shall have no responsibility with respect to the validity of this Agreement or with respect to the validity or
execution of any Right (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 Right; nor shall it by any act hereunder be deemed to make any representation
or warranty as to the authorization or reservation of any Common Stock to be issued pursuant to this Agreement or any Right or
as to whether any Common Stock will when issued be valid and fully paid and nonassessable.


 


6.5.        Acceptance
of Agency. The Rights Agent hereby accepts the agency established by this Agreement and agrees to perform the same upon the
terms and conditions herein set forth.


 


6.6         Waiver.

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 Rights 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.


 


7.           Miscellaneous
Provisions.
