to the Principal Amount.


 


4.2          Prepayment.
The Principal Amount may not be prepaid by the Company prior to the Maturity Date without the consent of Holder.


 


5.            Automatic
Conversion Upon Qualified Financing.


 


5.1          Conversion.
This Note shall be automatically canceled on the date of the initial closing of a Qualified Financing, and the outstanding Principal
Amount and all accrued but unpaid interest thereon shall be automatically converted, at the initial closing and on the same terms and
conditions of the Qualified Financing (including compliance with securities laws), into shares of Qualified Securities (or Shadow Preferred,

    4


     


    

 


6.            Conversion
Upon Change in Control. In the event of a Change in Control prior to the Maturity Date or prior to the conversion of this Note
pursuant to Section 5.1, at the election of the holders of a majority of the aggregate Principal Amount of all of the then issued and
outstanding Bridge Notes (the “Requisite Holders”), (i) the outstanding Principal Amount and all accrued but unpaid
interest thereon, as of the date of conversion pursuant to this Section 6, will be converted, immediately prior to the consummation of
the transaction constituting a Change in Control, into that number of shares of Preferred Conversion Stock (which will be rounded down
to the closest whole number) equal to the quotient obtained by dividing (x) the outstanding Principal Amount and all accrued but unpaid
interest thereon, immediately prior to such Conversion, by (y) the Preferred Conversion Price, or (ii) Holder shall receive an amount
equal to one and one half times (1.5X) the Principal Amount outstanding as of the date thereof concurrent with the consummation of the
transaction constituting a Change in Control (the “Cash Distribution”). Notwithstanding the foregoing or anything
herein contained to the contrary, to the extent that the consideration received as part of a Change in Control consists, in whole or
in part, of stock or other non-cash consideration (“Other Consideration”), and Holder elects to receive a Cash Distribution
as herein contemplated, the Company may, at its option, pay such Cash Distribution in cash or Other Consideration
in the same proportion as such Other Consideration is being paid to other holders of the Company’s securities. If any of the Company’s
securityholders are given a choice as to the form and amount of consideration to be received in a Change in Control, the Holder will
be given the same choice, provided that the Holder may not choose to receive a form of consideration that the Holder would be
ineligible to receive as a result of the Holder’s failure to satisfy any requirement or limitation generally applicable to the
Company’s securityholders, or under any applicable laws.


 


6.1          Ancillary
Agreements. In connection with a Conversion in connection with a Change in Control, other than in the case of the Cash Distribution,
Holder agrees to execute and deliver to the Company the Series Seed Transaction Documents and/or any documents reasonably requested by
the Company, including without limitation, a stock purchase agreement, an investors’ rights agreement, a right of first refusal
and co-sale agreement and a voting agreement, thereby agreeing to be bound by all obligations and receive all rights thereunder.


 


7.            Conversion
at Maturity Date; IPO.


 


7.1          Maturity
Date Conversion. In the event that neither a Qualified Financing nor a Change in Control shall have occurred on or before the Maturity
Date then, notwithstanding anything herein contained to the contrary, the outstanding Principal Amount and all accrued but unpaid interest
thereon as of the Maturity Date shall be automatically converted into shares of Preferred Conversion Stock as of the Maturity Date (the
 “Mandatory Conversion”). The number of shares (which will be rounded down to the closest whole number) of Preferred
Conversion Stock to be issued upon such conversion shall be equal to the quotient obtained by dividing (x) the outstanding Principal
Amount and all accrued but unpaid interest thereon immediately prior to the Maturity Date, by (y) the Preferred Conversion Price.


 


7.2          Ancillary
Agreements. In connection with the Mandatory Conversion, Holder agrees to execute and deliver to the Company the Series Seed Transaction
Documents and/or any documents reasonably requested by the Company, including without limitation, a stock purchase agreement, an investors’
rights agreement, a right of first refusal and co-sale agreement and a voting agreement, thereby agreeing to be bound by all obligations
and receive all rights thereunder.


 


7.3          IPO
Conversion. In the event that the Company shall consummate an IPO prior to a Qualified Financing, a Change in Control or the Maturity
Date, then, notwithstanding anything herein contained to the contrary, the outstanding Principal Amount and, at the election of the Company
all accrued but unpaid interest thereon to the date of conversion pursuant to this Section 7.3, shall be automatically converted into
shares of Common Stock as of immediately prior to the consummation of an IPO (the “IPO Closing Date”), at a per share
price equal to the IPO Conversion Price (the “IPO Conversion”). The number of shares (which will be rounded down to
the closest whole number) of Common Stock to be issued upon such conversion shall be equal to the quotient obtained by dividing (x) the
outstanding the outstanding Principal Amount and, at the election of the Company, all accrued but unpaid interest thereon (calculated
through the date that is not more than seven (7) days prior to the IPO Closing Date), by (y) the IPO Conversion Price. Accrued interest
which is not converted into Common Stock in accordance with the provisions hereof, shall be paid to Holder as soon as practicable following
the IPO Conversion.

a lockup agreement.

of, and not in limitation of any of the provisions of this Note, Holder acknowledges and agrees that, upon conversion of this Note as

instructions for the cancelation of this Note from Holder and neither the Company nor any successor in interest shall have any obligations
hereunder or in respect hereof.


 


8.2          No
Fractional Shares. If any fractional share of capital stock would, except for the provisions hereof, be deliverable upon conversion
of this Note, the Company, in lieu of delivering such fractional share, shall pay an amount equal to the value of such fractional share,
as determined by the per share conversion price used to effect such conversion.


 


8.3          Compliance
with Laws and Regulations. The Company shall take all such actions as may be necessary to assure that all shares of capital stock
issued upon conversion may be so issued without violation of any applicable law or governmental regulation or any requirement of any
domestic securities exchange upon which such shares of capital stock may be listed (except for official notice of issuance which shall
be immediately delivered by the Company upon such issuance).

reduce the Principal Amount of this Note or the rate of interest thereon.

similar nature) indebtedness of the Company, but excluding any indebtedness convertible into equity securities of the Company. Notwithstanding
the foregoing or anything herein contained to the contrary, the Bridge Notes shall rank pari passu with all other convertible
promissory notes outstanding as of the date hereof.

21.          Excessive
Interest. Notwithstanding any other provision herein to the contrary, this Note is hereby expressly limited so that the interest
rate charged hereunder shall at no time exceed the maximum rate permitted by applicable law. If, for any circumstance whatsoever, the
interest rate charged exceeds the maximum rate permitted by applicable law, the interest rate shall be reduced to the maximum rate permitted,
and if Holder shall have received an amount that would cause the interest rate charged to be in excess of the maximum rate permitted,
such amount that would be excessive interest shall be applied to the reduction of the Principal Amount owing hereunder and not to the
payment of interest, or if such excessive interest exceeds the unpaid balance of principal, such excess shall be refunded to the Company.


 


22.          Pari Passu Notes. The Holder acknowledges and agrees that the payment of all
or any portion of the outstanding Principal Amount of this Note and all interest hereon shall be pari passu in right of payment
and in all other respects to the other Bridge Notes. In the event the Holder receives payments in excess of the Holder’s pro

excess payments for the benefit of the holders of the other Bridge Notes and shall pay such amounts held in trust to such other holders
upon demand by such holders.
