(c)       Interest

(d)       Maturity.
Notwithstanding anything else herein the Repayment Amount (to the extent unpaid and not otherwise converted pursuant to section

3.      Payments.

 

(a)       Quarterly

rata among all of the Lenders based on the amount of their Loans to the Borrower.

 

 5.       Warrants.

 

5.1
Upon the earlier of closing of the Private Placement, an IPO or a Fundamental Change, the Company shall issue to Lender penny
warrants, in form attached hereto as Annex 1, for the purchase of Common Stock in an amount equal to the principal amount of Loan
(notwithstanding any repayment, in whole or in part, of the Loan) divided by the Conversion Price or in the event of an IPO, the
IPO Conversion Price.

 

5.2
(a)   Mandatory Conversion. Notwithstanding anything herein to the contrary, the Company may at any time on or
after a Qualified Public Offering deliver a notice to the Lender (a “Mandatory Conversion Notice” and
the date such notice is received by the Lender, the “Mandatory Conversion Notice Date”) to cause the Lender
to immediately convert any unpaid Repayment Amount as of such date into Common Stock at the IPO Conversion Price (a “Mandatory
Conversion”).

 

(b)
The Lender acknowledges that the Common Stock received pursuant to the Mandatory Conversion will be subject to lock-up provisions
contained herein. The Lender agrees not to sell, transfer, pledge, hypothecate or otherwise dispose of all or any part of such
Common Stock without the approval of the Company for a period of six months commencing upon the closing of the Company’s
initial public offering. Lender agrees to provide to the Company underwriters of any public offering such further agreements as
such underwriter may reasonably request in connection with this lock-up agreement.

 

Each
certificate for the Common Stock shall contain a legend on the face thereof, in substantially the following form:

 

“THE
SECURITIES EVIDENCED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS.
NO SALE OR DISPOSITION MAY BE EFFECTED WITHOUT (i) EFFECTIVE REGISTRATION STATEMENTS RELATED THERETO, (ii) AN OPINION OF COUNSEL
OR OTHER EVIDENCE REASONABLY SATISFACTORY TO THE COMPANY, THAT SUCH REGISTRATIONS ARE NOT REQUIRED, (iii) RECEIPT OF NO-ACTION
LETTERS FROM THE APPROPRIATE GOVERNMENTAL AUTHORITIES.

 

THE
SECURITIES EVIDENCED ARE SUBJECT TO A LOCKUP AND MAY NOT BE OFFERED, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED DURING
THE TERM OF THE LOCKUP.”

 

5.3       Adjustment
of Conversion Price. The Conversion Price and IPO Conversion Price shall be subject to adjustment from time to time as
follows:

 

(a)       Adjustments
for Stock Splits and Combinations. If the Company shall at any time or from time to time after the Date of the Loan, effect
a stock split of the outstanding Common Stock, the applicable Conversion Price in effect immediately prior to the stock split
shall be proportionately decreased. If the Lender shall at any time or from time to time after the Date of the Loan, combine the
outstanding shares of Common Stock, the applicable Conversion Price in effect immediately prior to the combination shall be proportionately
increased. Any adjustments under this Section 5.3(a) shall be effective at the close of business on the date the stock split or
combination occurs.

 

    4 

     

    

 

(b)       Adjustments
for Certain Dividends and Distributions. If the Lender shall at any time or from time to time after the Date of the Loan,
make or issue or set a record date for the determination of holders of Common Stock entitled to receive a dividend or other distribution
payable in shares of Common Stock, then, and in each event, the applicable Conversion Price in effect immediately prior to such
event shall be decreased as of the time of such issuance or, in the event such record date shall have been fixed, as of the close
of business on such record date, by multiplying, the applicable Conversion Price then in effect by a fraction:

 

(1)       the
numerator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of
such issuance or the close of business on such record date; and

 

(2)       the
denominator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time
of such issuance or the close of business on such record date plus the number of shares of Common Stock issuable in payment of
such dividend or distribution.

 

(c)       Adjustments
for Reclassification, Exchange or Substitution. If the Common Stock issuable upon conversion of this Note at any time
or from time to time after the Date of Loan shall be changed to the same or different number of shares of any class or classes
of stock, whether by reclassification, exchange, substitution or otherwise (other than by way of a stock split or combination
of shares or stock dividends provided for in Sections 5.3(a), or a reorganization, merger, consolidation, or sale of assets provided
for in Section 5.3(d)), then, and in each event, an appropriate revision to the Conversion Price shall be made and provisions
shall be made (by adjustments of the Conversion Price or otherwise) so that the Lender shall have the right thereafter to convert
this Note into the kind and amount of shares of stock and other securities receivable upon reclassification, exchange, substitution
or other change, by holders of the number of shares of Common Stock into which such Note might have been converted immediately
prior to such reclassification, exchange, substitution or other change, all subject to further adjustment as provided herein.

 

(e)       Adjustments
for Reorganization, Merger, Consolidation or Sales of Assets. If at any time or from time to time after the Date of Loan
there shall be a capital reorganization of the Company (other than by way of a stock split or combination of shares or stock dividends
or distributions provided for in Section 5.3(a), or a reclassification, exchange or substitution of shares provided for in Section
5.3 (c )), or a merger or consolidation of the Company with or into another corporation where the holders of Company outstanding
voting securities prior to such merger or consolidation do not own over fifty percent (50%) of the outstanding voting securities
of the merged or consolidated entity, immediately after such merger or consolidation, or the sale of all or substantially all
of the Company’s properties or assets to any other person (an “Organic Change”), then as a part of such
Organic Change, an appropriate revision to the Conversion Price shall be made and provision shall be made (by adjustments of the
Conversion Price or otherwise) so that the Lender shall have the right thereafter to convert such Note into the kind and amount
of shares of stock and other securities or property of the Company or any successor corporation resulting from Organic Change
into which such Note might have been converted immediately prior to such Organic Change.

 

    5 

     

    

 

(e)       Fractional
Shares. No fractional shares of Common Stock shall be issued upon conversion of this Note. In lieu of any fractional shares
to which the Lender would otherwise be entitled, the Company shall pay cash equal the fair market value of a share of Common Stock
as determined by the Company.

 

5.4    The
terms and conditions of this section 5 shall survive the termination or expiration of this Agreement.

 

6.    Characterization
of Investment. The parties agree that they shall treat this agreement as a loan for financial and tax and all other applicable
purposes, and not as equity. The Lender agrees to comply with all applicable laws governing the making of loans to businesses
in the jurisdiction in which they are resident.

 

7.      Default.
Each of the following events shall be an “Event of Default” hereunder:

 

(a)       Borrower
fails to pay any of the outstanding principal amount due under this Note on the date the same becomes due and payable or within
five business days thereafter or any accrued interest or other amounts due under this Note on the date the same becomes due and
payable or within five business days thereafter;

 

(b)       Borrower
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/limited liability company] action in furtherance of any of the foregoing; or

 

(c)       An
involuntary petition is filed against Borrower (unless such petition is dismissed or discharged within 60 days) under any bankruptcy
statute now or hereafter in effect, or a custodian, receiver, trustee or assignee for the benefit of creditors (or other similar
official) is appointed to take possession, custody or control of any property of Borrower.

 

Upon
the occurrence of an Event of Default hereunder, the entire unpaid amount of the Repayment Amount shall automatically be immediately
due, payable and collectible by Lender pursuant to applicable law.

 

8.       Parity
with Other Notes. The Borrower’s repayment obligation to the Lender under this Note shall be on parity with the Borrower’s
obligation to repay all Notes issued in the same offering. In the event that the Company is obligated to repay the Notes and does
not have sufficient funds to repay all the Notes in full, payment shall be made to the holders of the Notes on a pro rata basis.
The preceding sentence shall not, however, relieve the Company of its obligations to the Lender hereunder.

 

    6 

     

    

 

9.       Waiver.
Borrower waives presentment and demand for payment, notice of dishonor, protest and notice of protest of this Note, and shall
pay all costs of collection when incurred, including, without limitation, reasonable attorneys’ fees, costs and other expenses.
The right to plead any and all statutes of limitations as a defense to any demands hereunder is hereby waived to the full extent
permitted by law.

 

10.     Amendments.
Any provision of this instrument (other than the Repayment Amount) may be amended, waived or modified as follows: upon the written
consent of the Borrower the holders of a majority in principal of the Loan Amounts raised in this offering.

 

11.     Notice.

or sent by email to the relevant address listed on the signature page, or 48 hours after being deposited in the U.S. mail as certified
or registered mail with postage prepaid, addressed to the party to be notified at such party’s address listed on the signature
page, as subsequently modified by written notice.

 

12.     Governing
Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York applicable to
contracts made and to be performed wholly within such state. THE COMPANY AND PURCHASERS WAIVE ANY RIGHT TO A JURY TRIAL OF ANY
CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREIN, INCLUDING CLAIMS
BASED ON CONTRACT, TORT, BREACH OF DUTY AND ALL OTHER COMMON LAW OR STATUTORY BASES. Each party hereby irrevocably submits to
the exclusive jurisdiction of the state and federal courts sitting in the County of New York, State of New York for the adjudication
of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein

 

13.     Successors
and Assigns. Neither this instrument nor the rights contained herein may be assigned, by operation of law or otherwise, by
either party without the prior written consent of the other; provided, however, that the Company may assign this instrument in
whole, without the consent of the Investor, in connection with a reincorporation to change the Company’s domicile. Subject
to the foregoing, this instrument will be binding on the parties’ successors and assigns.

 

14.     No
Stockholder Rights. The Lender is not entitled, as a holder of this instrument, to vote or receive dividends or be deemed
the holder of capital stock of the Borrower for any purpose, nor will anything contained herein be construed to confer on the
Lender, as such, any of the rights of a stockholder of the Borrower or any right to vote for the election of directors or upon
any matter submitted to stockholders at any meeting thereof, or to give or withhold consent to any corporate action or to receive
notice of meetings, or to receive subscription rights or otherwise.

 

15.     Tax
Withholding. Lender hereby authorizes the Borrower to make any withholding required by law. Lender agrees to provide to Borrower
a Form W-9 or comparable form.

 

    7 

     

    

 

16.       Not
Effective Until Acceptable by Borrower. This Agreement is not effective until the Borrower has accepted the Lender’s
subscription.

degree of risk and is subject to many uncertainties. The Purchaser acknowledges that it understands that these risks and uncertainties
may adversely affect the Company’s business, operating results and financial condition, and the trading price for the Common
Stock if it is later quoted or traded on any securities trading market or exchange and Purchaser could lose all or part of its
investment.

 

3.

	 __	An
    employee benefit plan within the meaning of Title I of the Employee Retirement Income Security Act of 1974, where the
    investment decision is made by a plan fiduciary, as defined in Section 3(21) of such Act, which is either a bank, insurance
    company, or registered investment advisor, or an employee benefit plan which has total assets in excess of $5,000,000,
	 __	A
    private business development company as defined in Section 202(a)(22) of the Investment Advisors Act of 1940,
	 __	An
    organization described in Section 501(c)(3) of the Internal Revenue Code, a corporation or a partnership with total

	 __	A
    natural person whose individual net worth, or joint net worth with that person’s spouse, at the time of purchase exceeds $1,000,000.  For
    purposes of this Exhibit A-1, “net worth” means the excess of total assets at fair market value over total liabilities.
    For purposes of calculating net worth under this section, (i) the primary residence shall not be included as an asset, (ii)
    to the extent that the indebtedness that is secured by the primary residence is in excess of the fair market value of the
    primary residence, the excess amount shall be included as a liability, and (iii) if the amount of outstanding indebtedness
    that is secured by the primary residence exceeds the amount outstanding 60 days prior to the execution of this questionnaire,
    other than as a result of the acquisition of the primary residence, the amount of such excess shall be included as a liability.
	 __	Any
    trust, with total assets in excess of $5,000,000, not formed for the specific purpose of acquiring the Shares offered, whose
    purchase is directed by a sophisticated person as described in Section 506(b)(2)(ii) of Regulation D,
	 __	A
    natural person who had an individual income in excess of $200,000 in each of the two most recent calendar years, and has a
    reasonable expectation of reaching the same income level in the current calendar year.  For purposes of this Exhibit
    A-1, “income” means annual adjusted gross income, as reported for federal income tax purposes, plus (i) the amount
    of any tax-exempt interest income received; (ii) the amount of losses claimed as a limited partner in a limited partnership;
    (iii) any deduction claimed for depletion; (iv) amounts contributed to an IRA or Keogh retirement plan; (v) alimony paid;
    and (vi) any amount by which income from long-term capital gains has been reduced in arriving at adjusted gross income pursuant
