This
is to Certify That, FOR VALUE RECEIVED, HSAC 2 HOLDINGS, LLC, or his, her or its assigns (“Holder”), is entitled to
purchase, subject to the provisions of this Warrant, from HEALTH SCIENCES ACQUISITIONS CORPORATION 2, Cayman Islands exempted company
(the “Company”), 1,500,000 fully paid, validly issued and nonassessable ordinary shares of the Company, par value
$0.0001 per share (the “Ordinary Shares”) at a price of $11.50 per share. The number of Ordinary Shares to be received
upon the exercise of this Warrant and the price to be paid for each Ordinary Share may be adjusted from time to time as hereinafter set
forth. The Ordinary Shares deliverable upon such exercise, as adjusted from time to time, are hereinafter sometimes referred to as “Warrant
Shares,” and the exercise price for an Ordinary Share in effect at any time, as adjusted from time to time, is hereinafter
sometimes referred to as the “Exercise Price.”


 


(a)
EXERCISE OF WARRANT. This Warrant may be exercised in whole or in part at any time on the later of (i) 30 days after the consummation
by the Company of its initial merger, share exchange, asset acquisition, share purchase, reorganization or other similar business combination
with one or more businesses or entities (the “Business Combination”) (as described more fully in the Registration
Statement on Form S-1 (No. 333-239922) as filed with the Company or (ii) 12 months from the closing of the public offering of the Company’s
Ordinary Shares, and terminating at 5:00 p.m., New York City time on five years from the consummation of the Business Combination (the
“Expiration Date”). 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 at least twenty (20) days’ prior written notice of any such extension to registered holders of the Warrants and, provided
further that any such extension shall be identical in duration among all the Warrants.


 






     


     


    

 


(1)
This Warrant may be exercised by presentation and surrender hereof to the Company at its principal office with the Purchase Form annexed
hereto (the “Purchase Form”) duly executed and accompanied by payment of the Exercise Price for the number of Warrant
Shares specified in such Purchase Form (which may take the form of a “cashless exercise” pursuant to Section (a)(2)
if so indicated in the Purchase Form).




 


(2)
The Holder shall pay the Exercise Price in immediately available funds; provided, however, that the Holder may, in the Holder’s
sole discretion, satisfy its obligation to pay the Exercise Price through a “cashless exercise”, in which event the Company
shall issue to the Holder the number of Warrant Shares determined as follows:


 


X 
= Y(A-B)/A where


 


		X	=
                                            the number of Warrant Shares to be issued to the Holder.



 


Y 
= the total number of Warrant Shares with respect to which this Warrant is being exercised.


 


A
= the Fair Market Value (as defined below) of one Ordinary Share on the trading day immediately preceding the date on which Holder elects
to exercise this Warrant by means of a “cashless exercise.”


 


B
= the Exercise Price then in effect for the applicable Warrant Shares at the time of such exercise.


 


For
purposes of this Warrant, “Fair Market Value” means, for any security as of any date, the price determined by the first of
the following clauses that applies: (a) if the Ordinary Shares are then listed on a national securities exchange, the daily volume weighted
average price of the Ordinary Shares for such date (or the nearest preceding date) on the trading market on which the Ordinary Shares
are then listed as reported by Bloomberg L.P. (based on a Trading Day from 9:30 a.m. (New York City time) to 4:00 p.m. (New York City
time)), (b) if the Ordinary Shares are quoted on the OTC Bulletin Board or the OTC Market, the average closing bid price on such market
for the five most recently completed trading days, (c) if paragraphs (a) or (b) are not applicable, if an appraiser hired by the Company
has provided a report on the fair market value of an Ordinary Share within the 12-month period preceding the date on which Holder elects
to exercise this Warrant by means of a “cashless exercise,” the fair market value of a share of Ordinary Shares as determined
by such appraiser, or (d) if none of the foregoing is applicable, the price determined by the Board of Directors of the Company in good
faith.


 


(b)
EFFECTIVE TIME OF EXERCISE. Each exercise of this Warrant shall be deemed to have been effected immediately prior to the close of business
on the day on which the Purchase Form has been delivered to the Company (the “Exercise Date”) as provided in Section
(a). At such time, the person or persons in whose name or names any certificates for Warrant Shares shall be issuable upon such exercise
as provided in Section (c) below shall be deemed to have become the holder or holders of record of the Warrant Shares represented
by such certificates. Notwithstanding the foregoing, if the Holder or any assignee does not enter into the Shareholders’ Agreement
within three (3) business days of being requested to do so by the Company, then the exercise of this Warrant will be deemed to not have
been effective and void ab initio and the Holder or any assignee shall return any securities received by them pursuant to Section
(c) to the Company.

		(c)	DELIVERY
                                            TO HOLDER.



 


(1)
As soon as practicable after the exercise of this Warrant in whole or in part, and in any event within five (5) business days thereafter,
the Company will cause to be issued in the name of, and delivered to, the Holder, or as such Holder (upon payment by such Holder of any
applicable transfer taxes) may direct:


 


(A)
a certificate or certificates for the number of Warrant Shares to which such Holder shall be entitled, and


 


(B)
in case such exercise is in part only, a new warrant or warrants of like tenor, exercisable for in the aggregate the number of Ordinary
Shares equal (giving effect to any adjustment therein) to the number of Ordinary Shares called for on the face of this Warrant minus
the number of such shares purchased by the Holder upon such exercise.


 


(2)
To the extent permitted by law and except as provided in this Warrant, the Company’s obligations to issue and deliver Warrant Shares
in accordance with the terms hereof are absolute and unconditional, irrespective of any action or inaction by the Holder to enforce the
same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against any person or entity or any action
to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by the Holder
or any other person or entity of any obligation to the Company or any violation or alleged violation of law by the Holder or any other
person or entity, and irrespective of any other circumstance that might otherwise limit such obligation of the Company to the Holder
in connection with the issuance of Warrant Shares. Nothing herein shall limit the Holder’s right to pursue any other remedies available
to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect
to the Company’s failure to timely deliver certificates representing Warrant Shares upon exercise of the Warrant as required pursuant
to the terms hereof.


 


(d)
RESERVATION OF SHARES. The Company shall at all times reserve for issuance and/or delivery upon exercise of this Warrant such number
of Ordinary Shares (as adjusted pursuant to the terms hereof) as shall be required for issuance and delivery upon exercise of this Warrant.
The Company covenants that all Warrant Shares so issuable and deliverable shall, upon issuance and the payment of the applicable Exercise
Price in accordance with the terms hereof, be duly and validly authorized, issued and fully paid and nonassessable. The Company will
take all such action as may be reasonably necessary to assure that such Warrant Shares may be issued as provided herein without violation
of any applicable law or regulation, or of any requirements of any securities exchange or automated quotation system upon which the Ordinary
Shares may be listed.


 




    3


     


    

 


(e)
FRACTIONAL SHARES. No fractional shares or scrips representing fractional shares shall be issued upon the exercise of this Warrant. With
respect to any fraction of a share called for upon any exercise hereof, the Company shall pay to the Holder an amount in cash equal to
such fraction multiplied by the fair market value of an Ordinary Share.


 


(f)
LOSS OR DESTRUCTION OF WARRANT. Upon receipt by the Company of evidence satisfactory to it of the loss, theft, destruction or mutilation
of this Warrant, and (in the case of loss, theft or destruction) of reasonably satisfactory indemnification, and upon surrender and cancellation
of this Warrant, if mutilated, the Company will execute and deliver a new Warrant of like tenor and date.


 


(g)
RIGHTS OF THE HOLDER. The Holder shall not, by virtue hereof, be entitled to any rights of a shareholder in the Company, either at law
or equity, and the rights of the Holder are limited to those expressed in this Warrant and are not enforceable against the Company except
to the extent set forth herein.


 


(h)
CERTAIN ADJUSTMENTS. The Exercise Price and number of Warrant Shares issuable upon exercise of this Warrant are subject to adjustment
from time to time as set forth in this Section (h).


 


(1)
Share Capitalizations and Sub-Divisions. If the Company, at any time while this Warrant is outstanding, (i) declares a share capitalization
on its Ordinary Shares or otherwise makes a distribution on any class of shares that is payable in Ordinary Shares, (ii) subdivides its
outstanding Ordinary Shares into a larger number of shares, or (iii) combines its outstanding Ordinary Shares into a smaller number of
shares, then, in each such case, the Exercise Price shall be multiplied by a fraction, the numerator of which shall be the number Ordinary
Shares outstanding immediately before such event and the denominator of which shall be the number of Ordinary Shares outstanding immediately
after such event. Any adjustment made pursuant to this Section (h)(1) shall become effective immediately after the record date
for the determination of shareholders entitled to receive such dividend or distribution, and any adjustment pursuant to clause (ii) or
(iii) of this Section (h)(1) shall become effective immediately after the effective date of such subdivision or combination.


 


(2)
Number of Warrant Shares. Simultaneously with any adjustment to the Exercise Price pursuant to Section (h)(1), the number of Warrant
Shares that may be purchased upon exercise of this Warrant shall be increased or decreased proportionately, so that after such adjustment
the aggregate Exercise Price payable hereunder for the increased or decreased number of Warrant Shares shall be the same as the aggregate
Exercise Price in effect immediately prior to such adjustment.


 


(3)
Fundamental Transactions. If, at any time while this Warrant is outstanding (i) the Company effects any merger or consolidation of the
Company with or into another Person, (ii) the Company effects any sale of all or substantially all of its assets or a majority of its
Ordinary Shares is acquired by a third party, in each case, in one or a series of related transactions, (iii) any tender offer or exchange
offer (whether by the Company or a third party that is conducting such an offer pursuant to an agreement or arrangement with the Company)
is completed pursuant to which all or substantially all of the holders of Ordinary Shares are permitted to tender or exchange their shares
for other securities, cash or property, or (iv)  the Company effects any reorganization or reclassification of Ordinary Shares or
any compulsory share exchange pursuant to which the Ordinary Shares are effectively converted into or exchanged for other securities,
cash or property (other than as a result of a subdivision or combination of Ordinary Shares covered by Section (h)(1) above) (in
any such case, a “Fundamental Transaction”), then the Holder shall have the right thereafter to receive, upon exercise
of this Warrant, the same amount and kind of securities, cash or property as it would have been entitled to receive upon the occurrence
of such Fundamental Transaction if it had been, immediately prior to such Fundamental Transaction, the holder of the number of Warrant
Shares then issuable upon exercise in full of this Warrant without regard to any limitations on exercise contained herein (the “Alternate
Consideration”). The Company shall not effect any such Fundamental Transaction unless prior to or simultaneously with the consummation
thereof, any successor to the Company, surviving entity or the corporation purchasing or otherwise acquiring such assets or other appropriate
corporation or Person shall assume the obligation to deliver to the Holder, such Alternate Consideration as, in accordance with the foregoing
provisions, the Holder may be entitled to receive, and the other obligations under this Warrant. The provisions of this Section (h)(3)
shall similarly apply to subsequent transactions analogous of a Fundamental Transaction type.

the written request of the Holder, promptly compute such adjustment, in good faith, in accordance with the terms of this Warrant and
prepare a certificate setting forth such adjustment, including a statement of the adjusted Exercise Price and adjusted number or type
of Warrant Shares or other property issuable upon exercise of this Warrant (as applicable), describing the transactions giving rise to
such adjustments and showing in detail the facts upon which such adjustment is based. Upon written request, the Company will promptly

of the Company, reclassification of the shares of the Company, consolidation or merger of the Company with or into another corporation,
