Warrant Certificate

 

This
Warrant Certificate certifies that , or registered assigns, is the registered holder of warrant(s) evidenced hereby
(the “Warrants” and each, a “Warrant”) to purchase shares of Class A common stock, $0.0001
par value per share (“Common Stock”), of Blueprint Health Merger Corp., a Delaware corporation (the “Company”).
Each whole Warrant entitles the holder, upon exercise during the period set forth in the Warrant Agreement referred to below, to receive
from the Company that number of fully paid and non-assessable shares of Common Stock as set forth below, at the exercise price (the “Warrant
Price”) as determined pursuant to the Warrant Agreement, payable in lawful money (or through “cashless exercise”
as provided for in the Warrant Agreement) of the United States of America upon surrender of this Warrant Certificate and payment of the
Warrant Price at the office or agency of the Warrant Agent referred to below, subject to the conditions set forth herein and in the Warrant
Agreement. Defined terms used in this Warrant Certificate but not defined herein shall have the meanings given to them in the Warrant
Agreement.

 

Each whole Warrant is initially exercisable for one fully paid and
non-assessable share of Common Stock. No fractional shares will be issued upon exercise of any Warrant. If, upon the exercise of Warrants,
a holder would be entitled to receive a fractional interest in a share of Common Stock, the Company will, upon exercise, round down to
the nearest whole number of the number of shares of Common Stock to be issued to the holder. The number of shares of Common Stock issuable
upon exercise of the Warrants is subject to adjustment upon the occurrence of certain events as set forth in the Warrant Agreement.

 

[Form of Warrant]

 

The initial Warrant Price per share of Common Stock for any Warrant
is equal to $11.50 per share. The Warrant Price is subject to adjustment upon the occurrence of certain events as set forth in the Warrant
Agreement.

 

Subject to the conditions set forth in the Warrant Agreement, the Warrants
may be exercised only during the Exercise Period and to the extent not exercised by the end of such Exercise Period, such Warrants shall
become null and void. The Warrants may be redeemed, subject to certain conditions, as set forth in the Warrant Agreement.

 

Reference is hereby made to the further provisions of this Warrant
Certificate set forth on the reverse hereof and such further provisions shall for all purposes have the same effect as though fully set
forth at this place.

 

This Warrant Certificate shall not be valid unless countersigned by
the Warrant Agent, as such term is used in the Warrant Agreement.

 

     

     

    

 

This Warrant Certificate shall be governed by and construed in accordance
with the internal laws of the State of New York.

The Warrants evidenced by this Warrant Certificate are part of a duly
authorized issue of Warrants entitling the holder on exercise to receive shares of Common Stock and are issued or to be issued pursuant
to a Warrant Agreement dated as of      , 2021 (the “Warrant Agreement”), duly executed and
delivered by the Company to Continental Stock Transfer & Trust Company, a New York limited purpose trust company, as warrant
agent (or successor warrant agent) (collectively, the “Warrant Agent”), which Warrant Agreement is hereby incorporated
by reference in and made a part of this instrument and is hereby referred to for a description of the rights, limitation of rights, obligations,
duties and immunities thereunder of the Warrant Agent, the Company and the holders (the words “holders” or “holder”
meaning the Registered Holders or Registered Holder, respectively) of the Warrants. A copy of the Warrant Agreement may be obtained by
the holder hereof upon written request to the Company. Defined terms used in this Warrant Certificate but not defined herein shall have
the meanings given to them in the Warrant Agreement.

 

Warrants may be exercised at any time during the Exercise Period set
forth in the Warrant Agreement. The holder of Warrants evidenced by this Warrant Certificate may exercise them by surrendering this Warrant
Certificate, with the form of election to purchase set forth hereon properly completed and executed, together with payment of the Warrant
Price as specified in the Warrant Agreement (or through “cashless exercise” as provided for in the Warrant Agreement) at the
designated office of the Warrant Agent. In the event that upon any exercise of Warrants evidenced hereby the number of Warrants exercised
shall be less than the total number of Warrants evidenced hereby, there shall be issued to the holder hereof or his, her or its assignee,
a new Warrant Certificate evidencing the number of Warrants not exercised.

 

Notwithstanding anything else in this Warrant Certificate or the Warrant
Agreement, no Warrant may be exercised unless at the time of exercise (i) a registration statement covering the shares of Common
Stock to be issued upon exercise is effective under the Securities Act and (ii) a prospectus thereunder relating to the shares of
Common Stock is current, except through “cashless exercise” as provided for in the Warrant Agreement.

The Warrant Agreement provides that upon the occurrence of certain
events the number of shares of Common Stock issuable upon exercise of the Warrants set forth on the face hereof may, subject to certain
conditions, be adjusted. If, upon exercise of a Warrant, the holder thereof would be entitled to receive a fractional interest in a share
of Common Stock, the Company shall, upon exercise, round down to the nearest whole number of shares of Common Stock to be issued to the
holder of the Warrant.

 

Warrant Certificates, when surrendered at the designated office of
the Warrant Agent by the Registered Holder thereof in person or by legal representative or attorney duly authorized in writing, may be
exchanged, in the manner and subject to the limitations provided in the Warrant Agreement, but without payment of any service charge,
for another Warrant Certificate or Warrant Certificates of like tenor evidencing in the aggregate a like number of Warrants.

 

Upon due presentation for registration of transfer of this Warrant
Certificate at the office of the Warrant Agent a new Warrant Certificate or Warrant Certificates of like tenor and evidencing in the aggregate
a like number of Warrants shall be issued to the transferee(s) in exchange for this Warrant Certificate, subject to the limitations
provided in the Warrant Agreement, without charge except for any tax or other third-party charges imposed in connection therewith.

 

The Company and the Warrant Agent may deem and treat the Registered
Holder(s) hereof as the absolute owner(s) of this Warrant Certificate (notwithstanding any notation of ownership or other writing
hereon made by anyone), for the purpose of any exercise hereof, of any distribution to the holder(s) hereof, and for all other purposes,
and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary. Neither the Warrants nor this Warrant Certificate
entitles any holder hereof to any rights of a stockholder of the Company.
