offer, sell, contract to sell, pledge, grant any option to purchase, make any short sale or otherwise dispose of or distribute any shares
of Common Stock or Class B Common Stock or any securities convertible into, exercisable for, exchangeable for or that represent the right

which is designed to or which reasonably could be expected to lead to or result in a sale or disposition of the Restricted Securities

The foregoing shall not apply
to:

of which are exclusively the undersigned, its members or equity holders or members of their respective immediate family, or by will or
intestate succession upon the death of the undersigned;


 


(B)              
if the undersigned is a corporation, partnership, limited liability company or other business entity, distributions of shares of
Common Stock to members, partners, managers or stockholders of the undersigned;


 


(C)              
if the undersigned is a corporation, partnership, limited liability company or other business entity, any transfer made by the
undersigned to another corporation, partnership, limited liability company or other business entity so long as the transferee controls,

(D)              
transactions relating to Common Stock or other securities convertible into or exercisable or exchangeable for Common Stock acquired
by the undersigned in open market transactions after completion of the Business Combination;


 


(E)               
any transfers made by the undersigned by operation of law, such as pursuant to a qualified domestic order or in connection with
a divorce settlement; and


 


(F)               
any transfers to a charitable foundation controlled by the undersigned, its members or stockholders or any of their respective
immediate family;


 


provided, that, in the case of any transfer
or distribution pursuant to clause (A), (B), (C), (E) or (F), each donee, distributee or transferee, as applicable, shall execute and
deliver to the Company and Quantum-Si a lock-up letter in the form of this Agreement; and provided, further, that in the
case of any transfer or distribution pursuant to clause (A), (B), (C), (D), or (F) no filing by any party (donor, donee, transferor or

shall be required or shall be made voluntarily in connection with such transfer or distribution (other than a filing on a Form 5, Schedule
13G (or Schedule 13G/A) or Schedule 13F made after the expiration of the Lock-up Period referred to above). For purposes of this Agreement,
 “immediate family” means any relationship by blood, marriage or adoption, not more remote than first cousin.


 


 In furtherance of the
foregoing, the Company and any duly appointed transfer agent for the registration or transfer of the securities described herein are hereby
authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Agreement.


 


The undersigned hereby represents
and warrants that the undersigned has full power and authority to enter into this Agreement. All authority herein conferred or agreed
to be conferred and any obligations of the undersigned shall be binding upon the successors, assigns, heirs or personal representatives
of the undersigned.


 


The undersigned hereby represents
and warrants that it now has and, except as contemplated by this Agreement, will have good and marketable title to its Restricted Securities,
free and clear of all liens, encumbrances, and claims that could impact the ability of the undersigned to comply with the foregoing restrictions.
The undersigned agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against
the transfer of any Restricted Securities during the Lock-up Period.


 


Notwithstanding anything to
the contrary contained herein, if the Business Combination Agreement (other than the provisions thereof which survive termination)
shall terminate or be terminated prior to the Closing, the undersigned shall be released from all obligations under this Agreement. The
undersigned understands that the Company and Quantum-Si are proceeding with the Business Combination in reliance upon this Agreement.


 


This Agreement and any claim,
controversy or dispute arising under or related to this Agreement shall be governed by and construed in accordance with the laws of the
State of New York, without regard to the conflict of laws principles thereof.
