THIS
NOTE is issued pursuant to the terms of that certain Amended and Restated Equity Interest Purchase and Reorganization Agreement (“Purchase
Agreement”), by and among Marpai, Inc., a Delaware corporation (“Company”), Marpai Health, Inc.,
a Delaware corporation (“Marpai Health”), the stockholders and certain holders of convertible notes of Marpai Health,
including the undersigned lender (“Lender”), Continental Benefits, LLC, a Florida limited liability company, and WellEnterprises

HillCour, Inc., a Florida corporation, as well as that certain Note Exchange Agreement, dated as of the Note Date, between the Company,
the Lender and certain other holders of Marpai Health convertible notes.


 


FOR
VALUE RECEIVED, the Company hereby promises to pay to the order of the Lender, the principal sum of the Loan Amount, together with
interest thereon. This Note shall bear a simple interest rate of eight percent (8%) per annum based on a 365-day year. The obligation
to pay interest on this Note shall be cumulative. This Note is issued to Lender pursuant to Sections 1.1 and 2.3.2(c) of the Purchase
Agreement, in full satisfaction and repayment of principal and interest owed to Lender under that certain Convertible Promissory Note,
dated December 1, 2020, issued by Marpai Health, the Company’s wholly owned subsidiary (upon the consummation of the transactions
contemplated by the Purchase Agreement, in favor of Lender (the “Marpai Health Note”). In consideration of the Company’s
issuance of this Note, the Lender agrees that the Marpai Health’s obligations to Lender under the Marpai Health Note are deemed
fully satisfied and discharged, and no further sums shall be owed to Lender under such Marpai Health Note, which Lender has returned to
Marpai Health concurrently herewith for cancellation.


 


1.            Maturity
Date. If not otherwise converted pursuant to Section 3, the outstanding principal balance and unpaid accrued interest on this
Note shall be due two (2) years from the Note Date (the “Maturity Date”) or prior thereto upon the Lender’s
first written request following an Event of Default of the Company. The Maturity Date may be extended upon mutual consent of the Company
and the Lender.


 


2.            Note
Repayment. All repayments shall be made in lawful money of the United States of America by wire transfer to a bank account to be designated
by the Lender. All Notes issued pursuant to the Purchase Agreement, and any other Note outstanding as of the date hereof, shall rank equally
without preference or priority of any kind with respect to one another, and all payments with respect to any of the Notes that have not
been converted shall be applied ratably in proportion to the Loan Amounts represented thereby. The Company shall be entitled to repay
all or any portion of the principal or accrued interest outstanding under the Notes upon prior written notice to the Lender.


 






    


     


    

 


3.            Conversion.


 


3.1            Automatic
Conversion upon Initial Public Offering. If, on or after the date hereof and prior to
the earlier of the Maturity Date or the full repayment or conversion of the Notes, the Company (or a successor entity) closes an underwritten
public offering of its common stock (an “IPO”), then the entire principal amount of this Note and accrued interest
(calculated through the date that is ten (10) days prior to the closing of the IPO) will be converted automatically, without the
need for any action on the part of Company or the Lender, into unregistered shares of common stock of the Company (or successor entity,
as applicable) concurrently with the closing of the IPO. The number of shares of common stock issuable upon conversion of this Note will
be calculated by dividing the total of the principal amount of and accrued interest on this Note (calculated through the date set forth
above in this Section 3.1) then outstanding by 70% of the per share public offering price stated on the front cover of the final
prospectus for the IPO (before deduction of any underwriting commissions, expenses or other amounts). The Company will give the Lender
notice of the intended closing of an IPO, including the public offering price, provided that the failure to give such notice will not
affect the automatic conversion of this Note. In order to receive certificates representing the common stock, the Lender must cause the
original of this Note to be delivered to the Company, or if lost, stolen or destroyed, an affidavit and, if reasonably requested by the
Company, a reasonable indemnity as to the lost, stolen or destroyed original of this Note. Then, the Company (or successor entity) will
cause one or more stock certificates evidencing the Lender’s ownership of the number of conversion shares into which the principal
amount of, and interest accrued on, this Note has been converted to be delivered promptly to the Lender or as directed by the Lender.
From and after the IPO, this Note will represent only the right to receive shares of common stock (or shares of a successor entity’s
common stock).


 


3.2            Automatic
Conversion upon Qualified Financing. Notwithstanding the foregoing, at the closing of the Qualified Financing (as hereinafter defined),
the outstanding principal balance and unpaid accrued interest on this Note shall be automatically converted into the most senior class
of shares of the Company issued in such Qualified Financing (the “Shares”) at a price per share equal to the
lower of: (i) 70% of the original price per unit of such Shares on a fully diluted basis (in or (ii) a maximum company pre-money
valuation of Thirty-Five Million Dollars (US$35,000,000) each case, the “Conversion Price”). The exact number of Shares
to be issued to Lender upon conversion will be equal to the aggregate outstanding principal and unpaid accrued interest due on this Note,
divided by the Conversion Price. The issuance of such shares upon conversion of this Note shall be contingent upon execution and delivery
by the Lender of the agreements executed and delivered by investors in the Qualified Financing. The Lender shall thereupon receive all
of the rights, preferences and privileges granted to other investors in the Qualified Financing, including but not limited to any registration
and piggyback rights. “Qualified Financing” shall mean the next transaction or series of related transactions, other
than an IPO, following the date of the Purchase Agreement in which the Company issues and sells Shares to investors, which may be existing
stockholders of the Company, with gross proceeds to the Company of at least two million dollars (US$2,000,000), excluding the conversion
of Notes.


 


3.3            Discretionary
Conversion. Unless otherwise automatically converted upon an IPO or in a Qualified Financing, at any time prior to the Maturity Date
(or any time after the Maturity Date with the consent of the Company and including prior to a Change of Control that occurs before a Qualified
Financing or IPO) the Lender shall be entitled, by written notice to the Company, to convert the outstanding principal balance and unpaid
accrued interest on this Note, in whole or in part, into the most senior class of stock of the Company then outstanding, at a conversion
price based upon a maximum company pre-money valuation of Thirty-Five Million Dollars (US$35,000,000) on a fully diluted basis. The shares
issued upon said conversion shall have all preferential and associated rights with said class and given to the investors in the applicable
round of financing, and shall be identical in all terms except for said price. Any election to convert the Note pursuant to this Section 3.3
will be made in writing and delivered to the Company.


 


3.4            Repayment
Upon Change of Control. In the event the Company consummates a Change of Control (as defined below) prior to the Maturity Date and
prior to the conversion or repayment of this Note, then this Note shall become due and payable upon the date of consummation of such Change
of Control (and following the Company’s receipt of proceeds from a Change of Control) in an amount equal to the greater of: (i) one
and one half times (1.5x) the Loan Amount, plus any accrued and unpaid interest; or (ii) the net proceeds to be received by Lender
if Lender had converted this Note based on a price per share based on a pre-money valuation of the Company equal to $35,000,000, as calculated
on a fully diluted basis, immediately prior to the Change of Control. The Company will notify Lender in writing of a Change of Control
at least five (5) days before the anticipated closing of such Change of Control. A “Change of Control” means the
sale, conveyance, exclusive license outside of the ordinary course of business, or other disposition of all or substantially all of the
Company’s property or business, the Company’s merger with or into or consolidation with any other corporation, limited liability
company or other entity (other than a wholly owned subsidiary of the Company) if the holders of the voting securities of the Company that
are outstanding immediately prior to the consummation of such consolidation or merger do not, immediately after the consummation of such
consolidation or merger, hold voting securities that collectively possess at least a majority of the voting power of all the outstanding
securities of the surviving entity of such consolidation or merger or such surviving entity’s parent entity or the sale or disposition
of a majority of the voting securities of the Company; provided that the term “Change of Control” shall not include (a) a
merger or reorganization of the Company effected exclusively for the purpose of changing the domicile of the Company or tax-free reorganization
or (b) an equity financing in which the Company is the surviving corporation, including but not limited to the IPO.


 






    


     


    

 


4.            Unsecured
Obligation. The Lender hereby acknowledges and agrees that the obligations of the Company hereunder (including, without limitation,
in respect of repayment of the Loan Amount and the accrued but unpaid interest thereon) shall be an unsecured obligation of the Company
in all respects.


 


5.            Governing
Law; Venue. This Note and all acts and transactions pursuant hereto and the rights and obligations of the parties hereto shall be
governed, construed and interpreted in accordance with the laws of the State of New York without regard to the conflict of law provisions.
The competent courts of the State of New York shall have exclusive jurisdiction to resolve all disputes arising from or in connection
with this Note or the Purchase Agreement.


 


6.            Transfer;
Successors and Assigns. The Lender may not sell, assign, pledge, dispose of or otherwise transfer (collectively, “Transfer”)
this Note, unless the Lender obtains the Company’s prior written approval (such approval to be provided in the Company’s sole
and absolute discretion).


 


7.            Notices.
The notice provision of the Purchase Agreement shall apply to this Note.


 


8.            Amendments,
Modifications. Any amendment or modification of this Note shall require the prior written consent of the Company and the Lender.


 


9.            Miscellaneous.
The Company hereby expressly waives presentment, demand for payment, dishonor, notice of dishonor, protest, notice of protest and any
other formality.


 


10.            Stock
Reclassifications; Stock Splits, Combinations and Dividends. If the Shares issuable upon the conversion of this Note shall be changed
into the same or different number of Shares of any class or classes of stock, whether by reclassification, stock split, stock dividend,
or similar event, then and in each such event, the Lender, shall have the right thereafter to convert all or any portion of this Note
into the kind and amount of Shares and property receivable upon such capital reorganization, reclassification or other change which the
Lender would have received had this Note been converted immediately prior to such capital reorganization, reclassification or other change.


 






    


     


    

 


11.            Adjustments.
The Company will make an appropriate adjustment to the number of Shares issuable upon conversion and/or the Conversion Price thereof upon
any stock split, combination, dividend, distribution, recapitalization, reorganization, or similar event affecting the Company’s
capital stock other than cash dividends paid or payable from retained earnings (collectively, a "Stock Event"), so that
the Lender will receive, upon conversion, all Shares, dividends, rights and benefits to which the Lender would have been entitled had
Lender converted this Note prior to such Stock Event. The form of this Note need not be changed by reason of any such adjustment. Any
successor entity to the Company will execute and deliver to the Lender a supplement hereto acknowledging such entity's obligations under
this Note. The Company will make adjustments as soon as practicable following any Stock Event, and immediately thereafter give notice
to the Lender of all facts and calculations associated with such adjustment. Stock Event adjustments may be waived by the Lender, in its
sole and absolute discretion.


 


12.            Default.
If there shall be any Event of Default (as defined below) hereunder, at the option and upon the declaration of the Lender of this Note
and upon written notice to the Company (which election and notice shall not be required in the case of an Event of Default under Section 12(b) or
12(c)), this Note shall accelerate and all Loan Amount and unpaid accrued interest shall become due, payable and collectible. The occurrence
of any one or more of the following shall constitute an “Event of Default” hereunder:


 


(a)            The
Company fails to pay timely any of the Loan Amount due under this Note on the date the same becomes due and payable or any accrued interest
or other amounts due under this Note on the date the same becomes due and payable or within five (5) business days thereafter;


 


(b)            The
Company files any petition or action for relief under any bankruptcy, reorganization, insolvency or moratorium law or any other law for
the relief of, or relating to, debtors, now or hereafter in effect, or makes any assignment for the benefit of creditors or takes any
corporate action in furtherance of any of the foregoing; or


 


(c)            An
involuntary petition is filed against the Company (unless such petition is dismissed or discharged within sixty (60) days) under any bankruptcy
statute now or hereafter in effect, or a custodian, receiver, trustee, assignee for the benefit of creditors (or other similar official)
is appointed to take possession, custody or control of any property of the Company and is not removed within sixty (60) days from the
date of such appointment.


 


(d)            If
the Company shall admit in writing to its inability to pay its debts as they mature and Lender has elected to not convert this Note.


 


(e)            If
a judgment creditor shall file or commence any levy of attachment, execution or other similar process against the assets of the Company
valued in excess of $100,000 which potential loss is not covered by insurance or which proceeding is not being contested in good faith
by the Company, provided however, that such event shall not be an Event of Default if the Company cures such event within sixty (60) days
after receiving notice of the Event of Default contemplated under this subsection.


 


(f)            If
the Company commits fraud at any time in connection with this Note.


 


		13.	Default Remedies.



 


(a)            If
an Event of Default (other than an insolvency Event of Default) has occurred and is continuing, the Lender, by notice to the Company,
may declare the Loan Amount of this Note and all accrued interest thereon to be immediately due and payable, and upon any such declaration,
such Loan Amount and accrued interest shall thereupon become due and payable immediately within five (5) business days from the Lender’s
written request. In the event the Company fails to pay all outstanding Amounts within this five (5) business day period, the interest
rate on the unpaid and outstanding Loan Amount of this Note shall be increased to, and this Note shall bear interest at, a monthly rate
equal to one and a half percent (1.5%) or to the maximum rate permitted by law (the "Default Rate") from the expiration
of the five (5) business day period until such unpaid and outstanding Loan Amount of this Note is repaid in full. If an insolvency
Event of Default has occurred, the Loan Amount of this Note and accrued Interest thereon will become immediately due and payable without
any declaration or any act on the part of any Lender. Such declaration of acceleration may be rescinded and past defaults may be waived
by the Lender.


 






    


     


    

 


(b)            No
course of dealing or delay or failure on the part of the Lender to exercise any right under this Section shall operate as a waiver
of such right or otherwise prejudice the Lender’s rights, powers and remedies. The Company will pay or reimburse the Lender, to
the extent permitted by law, for all reasonable costs and expenses, including but not limited to reasonable attorneys’ fees, incurred
by the Lender in collecting any sums due on this Note or in otherwise enforcing any of the Lender's rights hereunder.


 


(c)            No
right or remedy herein conferred upon the Lender is intended to be exclusive of any other right or remedy contained herein or existing
at law, in equity, by statute or otherwise, and every such right or remedy shall be cumulative and shall be in addition to every other
such right or remedy contained herein and therein or now or hereafter existing at law, in equity, by statute or otherwise.


 


14.            Indemnity.
The Company agrees to indemnify and hold the Lender harmless from and against any and all suits, actions, proceedings, claims, damages,
losses, liabilities and expenses of any kind and nature whatsoever (including attorneys' fees and disbursements and other costs of investigation
or defense) that may be instituted or asserted against or incurred by the Lender as the result of credit having been extended, suspended
or terminated under this Note or with respect to the execution, delivery, enforcement, performance and administration of, or in any other
way arising out of or relating to, this Note or the transactions referred to herein and any actions or omissions with respect to any of
the foregoing, except to the extent that the Lender is finally determined by a court of competent jurisdiction to have resulted solely
from the gross negligence or willful misconduct of the Lender.


 


15.            Replacement
of Note. If the Lender of record loses this Note, the Company shall issue an identical replacement Note to the Lender upon the Lender’s
delivery to the Company of an executed lost note affidavit stating the facts surrounding such loss of this Note and an executed indemnity
agreement indemnifying and holding harmless the Company against any losses incurred or liabilities suffered by the Company or claims against
the Company by any other holders or transferees of this Note related to or from the issuance of the replacement Note by the Company, which
lost note affidavit and indemnity agreement shall be in a form reasonably satisfactory to the Company.


 


16.            Reinstatement.
This Note shall continue to be effective, or be reinstated, as applicable, if at any time payment of all or any part hereof is rescinded
or must otherwise be returned or restored by the Lender upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of
the Company, as though such payments had not been made.


 


17.            Additional
Covenants. Until this Note is paid in full, the Company shall not without the prior written consent of the Lenders holding a majority
in interest of the Loan Amount. (such consent which shall not be unreasonably delayed, withheld, or conditioned): (i) issue any securities
other than strictly pursuant to a Qualified Financing, IPO or pursuant to a duly adopted Stock Incentive Plan; (ii) incur or
agree to incur any indebtedness that is senior to this Note (except for the SQN Note as hereinafter defined) ; (iii) make any loans
to, or assume or guarantee any debt or other obligations of another person or entity in excess of $10,000; ; (iv) enter into or modify
any affiliated party transaction or pay current officers and directors in excess of that which has previously been disclosed in writing
to the Lender; (v) place any liens or encumbrances on, or cause any liens or encumbrances to be placed on, or transfer, convey, assign,
pledge or grant any security interests in, the capital stock or assets or properties of the Company other than those liens that may be
granted to SQN under the SQN Note; or (vi) declare or pay any dividends or distributions on its capital stock until this Note is
paid in full.

balance sheet, income statement and statement of cash flow (the "Financial Statements") of the Company and its subsidiaries,

the Chief Executive Officer or Chief Financial Offer of the Company certifying that (i) such Financial Statements are complete, true
and correct and (ii) to his or her actual knowledge, the Company is not in default of any of its covenants made hereunder.


 


(b)            Annual
Reports. Within ninety (90) days following the close of each fiscal year of the Company, the Financial Statements for such fiscal
