of Series 2 Note.


 


		3.1	Conversion Events.



 


		(a)	Qualifying IPO.



 


		(i)	If a Qualifying IPO occurs prior to the Maturity Date, then



 


effective
as of the closing date of such Qualifying IPO, the Series 2 Note Obligation Amount shall automatically convert in full into a number
of Conversion Shares equal to: (x) the outstanding Series 2 Note Obligations Amount on such closing date, divided by
(y) a price per share (the “IPO Conversion Price”) equal to (A) 90% of the gross price per share at which
Common Stock is sold in the Qualifying IPO, if the Qualifying IPO occurs on or before September 30, 2022; (B) 85% of the gross
price per share at which Common Stock is sold in the Qualifying IPO, if the Qualifying IPO occurs on or after October 1, 2022 but
on or before December 31, 2022; or (C) 80% of the gross price per share at which Common Stock is sold in the Qualifying IPO,
if the Qualifying IPO occurs on or after January 1, 2023. If, in the case of a Qualifying IPO described in clause (b) of the
definition thereof, such gross price per share is not readily identifiable, then such gross price per share shall be deemed to
equal the average of the last reported per share sale price of the successor entity’s common stock on the public securities market
on which it is primarily traded for the twenty (20) consecutive trading days immediately prior to the closing date of such Qualifying
IPO; provided, however, that if no sales of such common stock occurred on any such trading day, the mean between the closing
 “bid” and “asked” per share prices for such common stock on such trading day shall be used in lieu of the last
reported per share sale price for such trading day.


 


(ii)            No later than five
(5) business days following the closing date of a Qualifying IPO, the Company shall provide the Holder with written notice of the
conversion of the Series 2 Note Obligation Amount into Conversion Shares in accordance with Section 3.1(a)(i), specifying the
Series 2 Note Obligation Amount so converted, the IPO Conversion Price, the number of Conversion Shares into which such Series 2
Note Obligation Amount has been converted and the effective date of such conversion, and requesting the Holder to surrender this Series 2
Note to the Company in the manner and at the place designated in such notice. The Holder agrees to deliver the original of this Series 2
Note to the Company for cancellation not later than ten (10) days after its receipt of such notice; provided, however, that from and after the closing date of such Qualifying IPO, the Series 2 Note Obligation Amount shall be deemed to have been fully
converted into Conversion Shares and this Series 2 Note shall be deemed to have been paid in full, whether or not it is delivered
for cancellation as set forth in this sentence. From and after the closing date of such Qualifying IPO, the Holder shall be treated for
all purposes as the record holder of the Conversion Shares into which the Series 2 Note Obligation Amount has been converted in accordance
with this Section 3.1(a). The Holder shall be entered into the register of holders of Common Stock effective as of the closing date
of the Qualifying IPO and the Company shall promptly provide (or cause to be provided) to the Holder evidence of same.

(iii)          Notwithstanding
anything in this Series 2 Note to the contrary, if there shall occur a Qualifying IPO described in clause (b) of the
definition thereof in which the Common Stock is converted into or exchanged for securities, cash or other property then, upon
conversion of the Series 2 Note Obligation Amount pursuant to Section 3.1(a)(i), the Holder shall be entitled to
receive (in lieu of the Conversion Shares) the kind and amount of securities, cash or other property which the holder would have
been entitled to receive if (a) such Series 2 Note Obligation Amount (or portion thereof) had been converted into the
number of Conversion Shares that the Holder would otherwise have been entitled to receive pursuant to Section 3.1(a)(i)
and (b) immediately after giving effect to such conversion, the number of Conversion Shares determined pursuant to clause
(a) above had been sold, exchanged or otherwise disposed of by such Holder in accordance with the terms of such Qualifying IPO
(such securities, cash and other property, the “Alternative Conversion Consideration”). In the event any such
event occurs, the Company shall make such equitable adjustments in the application of the provisions of this Section 3.1(a) as
it determines are appropriate with respect to the rights and interests thereafter of the Holder, to the end that the provisions set
forth in this Section 3.1(a) shall thereafter be applicable, as nearly as reasonably may be, in relation to the
Alternative Conversion Consideration deliverable upon conversion of the Series 2 Note Obligation Amount.


 


(b)            Change
of Control.


 


(i)            In
the event that a Change of Control is expected to occur prior to the closing date of a Qualifying IPO, the Company shall deliver written
notice to the Holder (the “Change of Control Notice”) not less than thirty (30) days prior to the anticipated effective
date of such Change of Control where practicable (or, if it is not practicable to deliver the Change of Control Notice prior to the effective
date of a Change of Control and the Change of Control does not occur by reason of a merger, consolidation, recapitalization or reorganization
of the Company), not more than five (5) days following the effective date of such Change of Control). The Change of Control Notice
shall include (A) the material terms and conditions of the proposed transaction, including the material terms of all transaction
documents to be entered into by other holders of the Common Stock in connection with the applicable Change of Control, (B) the anticipated
date on which the Change of Control will occur, and (C) the Maturity Conversion Price. Following delivery of a Change of Control
Notice, the Holder will be required to make the applicable election (a “Change of Control Election”) as set forth
in Section 3.1(b)(ii) with respect to this Series 2 Note by delivering written notice thereof to the Company not
later than fifteen (15) days after delivery of the applicable Change of Control Notice (such fifteenth (15th)
day, the “Change of Control Election Deadline Date”). Following delivery of a Change of Control Notice, the Company
shall promptly provide the Holder with such additional information regarding the terms of the Change of Control as the Holder may reasonably
request, subject to any restrictions on the Company pursuant to any applicable confidentiality agreement. Any Change of Control Election
made by the Holder in connection with a Change of Control shall be irrevocable once delivered to the Company, except that if the Change
of Control in respect of which such Change of Control Election is given does not occur, then such Change of Control Election will be
considered null and void and of no further force or effect from and after the date as of which (x) such Change of Control is abandoned
or (y) it becomes readily apparent that such Change of Control will no longer occur.

(ii)             Following the delivery
of a Change of Control Notice, the Holder may elect, by written notice delivered to the Company on or prior to the Change of Control Election
Deadline Date (a “Change of Control Election Notice”), that upon the effective date of such Change of Control and immediately
before giving effect thereto (or within 10 days after the delivery of such Change of Control Election Notice, if the Change of Control
Notice has been delivered after such effective date in accordance with Section 3.1(b)(i)), that either: (x) the Company
shall prepay the entire Series 2 Note Obligation Amount in full in cash (upon which prepayment this Series 2 Note shall cease
to be outstanding); or (y) the Series 2 Note Obligation Amount shall be converted fully into shares of Common Stock, with the
number of Conversion Shares to be received by the Holder in connection with such conversion to equal the quotient obtained by dividing
(A) the Series 2 Note Obligation Amount as of the date of the closing of such Change of Control by (B) the Maturity
Conversion Price. If the Holder does not deliver a Change of Control Election Notice on or prior to the applicable Change of Control Election
Deadline Date, then the Holder will be deemed to have made the election specified under clause (x) of this Section 3.1(b)(ii).


 


(iii)            Upon any conversion
of this Series 2 Note pursuant to Section 3.1(b)(ii) into shares of Common Stock, the Holder agrees to execute and deliver,
and shall be bound upon such conversion by the obligations in, all transaction documents entered into by other holders of the Common Stock
in connection with the applicable Change of Control. In connection with any conversion of this Series 2 Note pursuant to Section 3.1(b)(ii) into
shares of Common Stock, the Holder agrees to deliver the original of this Series 2 Note to the Company for cancellation not later
than ten (10) days after the effective date of such conversion (as determined in accordance with the foregoing provisions of this
Section 3.1(b)); provided, however, that from and after such effective date, (x) the Series 2
Note Obligation Amount shall be deemed to have been fully converted into Conversion Shares and this Series 2 Note shall be deemed
to have been paid in full, whether or not it is delivered for cancellation as set forth in this sentence, and (y) the Holder shall
be treated for all purposes as the record holder of the Conversion Shares into which the Series 2 Note Obligation Amount has been
converted in accordance with this Section 3.1(b). The Holder shall be entered into the register of holders of Common Stock effective
as of such effective date and the Company shall promptly provide (or cause to be provided) to the Holder evidence of same.


 


(c)           Maturity
Date.


 


(i)              If, prior to the Maturity
Date, the Series 2 Note Obligation Amount has not been fully converted into Conversion Shares pursuant to Section 3.1(a)(i) or
3.1(b)(ii) or fully repaid in cash pursuant to Section 3.1(b)(ii), then in lieu of paying all or portion of the Series 2
Note Obligation Amount in cash as otherwise required by Section 2.2 on the Maturity Date, the Company (in its sole discretion) may
convert this Series 2 Note, in whole or in part, into shares of Common Stock on the Maturity Date, with the number of Conversion
Shares to be received by Holder in connection with such conversion to be equal to the quotient obtained by dividing (x) the Series 2
Note Obligation Amount as of the Maturity Date (or the portion thereof to be so converted, as the case may be) by (y) the
Maturity Conversion Price. The Company shall provide written notice to the Holder of its election pursuant to the immediately preceding
sentence no later than the Maturity Date.

(ii)             In connection with
the conversion and/or repayment in full of the Series 2 Note Obligation Amount on the Maturity Date pursuant to Sections 3.1(c)(i) and
2.2, the Holder agrees to deliver the original of this Series 2 Note to the Company for cancellation as promptly as practicable after
the Maturity Date; provided, however, that from and after such conversion and/or repayment in full, this Series 2
Note shall be deemed to have been paid in full, whether or not it is delivered for cancellation as set forth in this sentence. Any conversion
of this Series 2 Note pursuant to Section 3.1(c)(i) shall be deemed to have occurred as of the Maturity Date, and from
and after the Maturity Date, the Holder shall be treated for all purposes as the record holder of any Conversion Shares into which the
Series 2 Note Obligation Amount (or a portion thereof) has been converted in accordance with this Section 3.1(c). In connection
with any such conversion, the Holder shall be entered into the register of holders of Common Stock effective as of the Maturity Date and
the Company shall promptly provide (or cause to be provided) to the Holder evidence of same.


 


3.2          Fractional
Interests; Effect of Conversion. In lieu of the Company issuing any fractional securities to the Holder upon any conversion of this
Series 2 Note, the Company shall have the option of paying to the Holder an amount equal to the product obtained by multiplying
the applicable conversion price by the fraction of the security not issued, but provided such amount is at least equal to ten dollars
($10) and if not, then such amount less than ten dollars ($10) shall not be paid or payable and such fractional security shall be cancelled.
Upon conversion of this Series 2 Note in full and the payment of the amount (if any) specified in this paragraph, this Series 2
Note shall be deemed to have been paid in full and the Company shall be deemed to have satisfied all its obligations under or in respect
of this Series 2 Note, whether or not the original of this Series 2 Note has been delivered to the Company for cancellation.


 


3.3          No Other Conversion.
Except as expressly provided in Section 3.1, neither the Series 2 Note Obligation Amount nor any portion thereof may be converted
into shares of Common Stock.


 


3.4           Delivery
of Securities Upon Conversion.


 


(a)           As soon as reasonably
practicable after any Conversion Date, the Company shall deliver to the Holder a certificate or certificates evidencing the Conversion
Shares issuable to the Holder. The Holder understands and acknowledges that all certificates representing Conversion Shares, as well as
all certificates in exchange for or in substitution of the foregoing securities, until such time as the same is no longer required under
applicable requirements of U.S. Securities Laws or any other applicable securities laws, shall bear the legends set forth in the Subscription
Agreement.


 






    8


     


    

 


(b)           The
issuance of certificates evidencing Conversion Shares in connection with any conversion of this Series 2 Note shall be made without
charge to the Holder for any transfer, stamp or similar tax in respect thereof or other out-of-pocket expense incurred by the Company
in connection with such conversion and the issuance of such Conversion Shares; provided, however, that the
Company shall not be required to pay any tax that may be payable in respect of any issuance of Conversion Shares to any Person other
than the Holder or any withholding, income or similar tax due by or with respect to the Holder in connection with such Conversion Shares
or as a result of such conversion. The Company shall not be required to make any such issuance or delivery of such certificates unless
and until the Holder or other Person otherwise entitled to such issuance or delivery has paid the amount of any tax payable by it pursuant
to the proviso in the immediately preceding sentence or has established, to the satisfaction of the Company, that no such tax payable.
Upon any conversion of this Series 2 Note, the Company shall take all such actions as are necessary in order to ensure that the
Conversion Shares issued upon such conversion shall be validly issued, fully paid and non-assessable.


 


3.5           Portfolio Interest.
Notwithstanding anything in this Series 2 Note to the contrary, in the event that, the holder is not a United States person (as defined
by Section 7701(a)(30) of the U.S. Internal Revenue Code of 1986, as amended (the “Code”)) and on the date of
any conversion of this Series 2 Note into Conversion Shares pursuant to Section 3.1, the interest payable under this Series 2
Note does not qualify as “portfolio interest” (“Portfolio Interest”) as defined in Section 871(h) of
the Code, or the exemption from withholding for Portfolio Interest set forth in Section 871(h) of the Code is no longer in effect,
then so much of the accrued interest as is equal to the amount that the Company is required to withhold under Section 1441(a) of
the Code shall not be converted into Conversion Shares pursuant to Section 3.1, and the Company shall withhold such amount in compliance
with Section 1441(a) of the Code.


  


4.             Conversion
Price Adjustments.


 


4.1           If, at any time when any
Series 2 Note Obligation Amount remains outstanding hereunder:


 


(a)           the Company effects
a subdivision of the outstanding Common Stock, or shall declare a dividend payable on the Common Stock in additional shares of Common
Stock, then the Maturity Conversion Price, as in effect immediately before such subdivision or dividend, shall be decreased in inverse
proportion to the increase in the aggregate number of outstanding shares of Common Stock resulting from such subdivision or dividend;
and


 


(b)           the Company combines
the outstanding shares of Common Stock, then the Maturity Conversion Price, as in effect immediately before such combination, shall be
increased in inverse proportion to the decrease in the aggregate number of outstanding shares of Common Stock resulting from such combination.


 


4.2           If, at any time prior to
the full conversion of the Series 2 Note Obligation Amount into Conversion Shares hereunder, the Company effects a dividend or other
distribution of cash or other assets to the holders of the Common Stock (other than a dividend payable in additional shares of Common
Stock), then the Maturity Conversion Price, as in effect immediately before such distribution, shall be decreased by an amount equal to
the per share value of the cash or assets so distributed. In the event that such per share value is not readily identifiable, it shall
be determined by the Company acting in good faith.

5.             Certain
Representations.


 


5.1          All corporate and stockholder
action on the part of the Company’s directors and stockholders necessary for the authorization, execution and delivery of, and the
performance of all obligations of the Company under, this Series 2 Note has been taken. This Series 2 Note has been duly executed

of, the constitutive documents of the Company or any material agreement or instrument to which the Company or any subsidiary of the Company
is a party.


 


6.             Status.

in respect of any matters whatsoever, or any other rights or liabilities as a stockholder, prior to conversion hereof into Conversion
Shares.


 


7.             Covenants.

If the Company becomes aware that any one or more events occur which constitute or which, with the giving of notice or the lapse of time
or both, would constitute an Event of Default, or if the holder of any other Series 2 Note notifies the Company is writing that it
believes such an event has occurred, the Company shall give prompt written notice thereof to the Holder, specifying the nature and status
of the actual, potential or alleged Event of Default.

7.3          Other Indebtedness.
The Company shall not incur any new Indebtedness which is intended to rank pari passu or senior in right of payment to the Series 2
Notes; provided, however, that this Section 7.3 does not apply to any Indebtedness incurred which is used to
repay the Series 2 Notes and accrued interest thereon in full before any other permitted use (other than a concurrent repayment in
full of the Series 1 Notes).

		8.2	Effects of Default.



 


(a)    If
an Event of Default under Section 8.1(a), (b) or (c) occurs and is continuing, then and in every such case the Holder
may declare this Series 2 Note to be due and payable immediately, by a notice in writing to the Company, and upon any such declaration,
the Company shall pay to the Holder the outstanding Principal Amount of this Series 2 Note plus all accrued and unpaid interest
in cash through the date the Series 2 Note is paid in full; provided, however, that in the event the aggregate original
principal amount of this Series 2 Note and the other Series 2 Notes (if any) owned by the Holder and its Affiliates is less
than $1,000,000, such declaration shall be without effect unless and until similar declarations have been made by the Required Holders
in respect of such Event of Default. Any declaration made by the Holder pursuant to this Section 8.2(b) in connection with
any Event of Default under Section 8.1(a), (b) or (c) may be rescinded and annulled by the Holder at any time prior to
payment hereunder and the Holder shall have all rights as a holder of the Series 2 Note until such time, if any, as the Holder receives
full payment pursuant to this Section 8.2; provided, however, that in the event the aggregate original principal amount
of this Series 2 Note and the other Series 2 Notes (if any) owned by the Holder and its Affiliates is less than $1,000,000,
such declaration shall automatically be rescinded and annulled if the Required Holders have rescinded and annulled the corresponding
declaration made by them in respect of the applicable Event of Default. No rescission or annulment pursuant to the immediately preceding
sentence shall affect any subsequent Event of Default.


 


(b)  Notwithstanding
the foregoing, in the event that an Event of Default under Section 8.1(d), (e) or (f) occurs, the outstanding Principal
Amount of this Series 2 Note plus accrued and unpaid interest, and other amounts owing in respect thereof through the date of acceleration,
shall become immediately due and payable in cash. In connection with the automatic acceleration described in the immediately preceding
sentence, the Holder need not provide, and the Company hereby waives, any presentment, demand, protest or other notice of any kind, and
the Holder may immediately and without expiration of any grace period enforce any and all of its rights and remedies hereunder and all
other remedies available to it under applicable law.


 


8.3           Remedies, Other Obligations,
Breaches and Injunctive Relief. The remedies provided in this Series 2 Note shall be cumulative and in addition to all other
remedies available under this Series 2 Note at law or in equity (including a decree of specific performance and/or other injunctive
relief), and nothing herein shall limit the Holder’s right to pursue damages for any failure by the Company to comply with the terms
of this Series 2 Note. The Company acknowledges that a breach by it of its obligations under Section 3 of this Series 2
Note may cause irreparable harm to the Holder and that the remedy at law for any such breach may be inadequate. The Company therefore
agrees that, in the event of any such breach or threatened breach, the Holder shall be entitled, in addition to all other available remedies,
to an injunction restraining any such breach or any such threatened breach, without the necessity of showing economic loss and without
any bond or other security being required


 


8.4           Remedies Not Waived;
Exercise of Remedies. No course of dealing between the Company and the Holder or any delay in exercising any rights hereunder shall
operate as a waiver by the Holder. No failure or delay by the Holder in exercising any right, power or privilege under this Series 2
Note shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof
or the exercise of any other right, power or privilege. The rights and remedies herein provided shall be cumulative and not exclusive
of any rights or remedies provided by Applicable Law.

9.
            Amendments. The terms of this Series 2 Note may be modified, amended or waived in writing by (and no such modification,
amendment or waiver shall be effective unless approved in writing by) the Company and the Required Holders; provided, however,
that no modification, amendment or waiver of this Section 9 or the material economic terms of this Series 2 Note, including
(a) Section 6.2, (b) any change in the amount or time of any prepayment or repayment of principal of, or reduction in the
rate or change in the time of payment or method of computation of the interest on, this Series 2 Note, or (c) any change in
the method or process for calculating the number of Conversion Shares to be issued upon any conversion of this Series 2 Note pursuant
to Section 3.1, in each case will be effective unless it is consented to in writing by the Holder.


 


10.           Miscellaneous.


 


10.1          Severability.
If any provision of this Series 2 Note shall be held to be invalid or unenforceable, in whole or in part, neither the validity nor
the enforceability of the remainder hereof shall in any way be affected.

Series 2 Note provides for notice of any event, such notice shall be given (unless otherwise herein expressly provided) in writing

facsimile or other electronic transmission, and shall be deemed given when so delivered personally, sent by facsimile or other electronic
transmission (confirmed in writing) or mailed. Notices shall be addressed, if to Holder, to its address as provided in the Subscription
Agreement (or such other address as it may specify by written notice to the Company) or, if to the Company, to its principal office.


 


10.3          Governing Law. This
Series 2 Note shall be governed by, and construed in accordance with, the laws of the State of Delaware (without giving effect to
any conflicts or choice of law provisions that would cause the application of the domestic substantive laws of any other jurisdiction).


 


10.4          Forum.
The Holder and the Company hereby agree that any dispute which may arise out of or in connection with this Series 2 Note shall be
adjudicated before a federal or state court of competent jurisdiction in the State of Delaware and they hereby submit to the exclusive
jurisdiction of such courts, as well as to the jurisdiction of all courts to which an appeal may be taken from such courts, with respect
to any action or legal proceeding commenced by either of them and hereby irrevocably waive any objection they now or hereafter may have
respecting the venue of any such action or proceeding brought in such a court or respecting the fact that such court is an inconvenient
forum.


 


10.5        
Headings; Section References. The headings of the sections of this Series 2 Note
are inserted for convenience only and do not constitute a part of this Series 2 Note. Unless the context otherwise requires, all
references in this Series 2 Note to any “Section” are to the corresponding Section of this Series 2 Note.


 






    13


     


    

 


10.6          No
Recourse against Others. The obligations of the Company under this Series 2 Note are solely obligations of the Company and no
officer, employee, director or stockholder shall be liable for any failure by the Company to pay amounts in respect of this Series 2
Note when due or to perform any other obligation.


 


10.7          Binding
Effect. This Series 2 Note shall be binding upon and inure to the benefit of both parties hereto and their respective permitted
