and the undersigned individual (“Purchaser”).


 


In consideration of the mutual covenants and
representations set forth below, the Company and Purchaser agree as follows:


 


1.            Purchase and Sale
of the Shares. Subject to the terms and conditions of this Agreement, the Company agrees to sell to Purchaser, and Purchaser
agrees to purchase from the Company at the Closing (as defined below) 750 shares of the Company’s Common Stock (the “Shares”)
at a price of $0.1 per share (the “Purchase Price”).


 


2.            Terms
of Purchase. The purchase and sale of the Shares shall occur at a closing (the “Closing”) to be held on
the date first set forth above. The Closing will take place at the principal office of the Company. At the Closing, Purchaser
shall deliver a signed copy of this Agreement and the Purchase Price and the Company will issue, as promptly thereafter as practicable,
a stock certificate, registered in the name of Purchaser, representing the Shares.


 


3.            Restrictions on
Transfer. Purchaser understands and agrees that the Company shall cause the legends set forth below, or substantially equivalent
legends, to be placed upon any certificate(s) evidencing ownership of the Shares, together with any other legends that may be required
by the Company or by applicable state or federal securities laws:


 


THE SECURITIES REPRESENTED HEREBY HAVE NOT
BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR UNDER THE SECURITIES LAWS OF CERTAIN STATES.
THESE SECURITIES MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED EXCEPT AS PERMITTED UNDER THE ACT AND
APPLICABLE STATE SECURITIES LAWS PURSUANT TO REGISTRATION OR AN EXEMPTION THEREFROM. THE ISSUER OF THESE SECURITIES MAY REQUIRE
AN OPINION OF COUNSEL SATISFACTORY TO THE ISSUER THAT SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION OTHERWISE COMPLIES
WITH THE ACT AND ANY APPLICABLE STATE SECURITIES LAWS.


 


THE SECURITIES REPRESENTED BY THIS CERTIFICATE
ARE SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER AND LOCK-UP PERIOD AS SET FORTH IN THE COMMON STOCK PURCHASE AGREEMENT BETWEEN
THE ISSUER AND THE ORIGINAL HOLDER OF THESE SECURITIES, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE ISSUER.
SUCH TRANSFER RESTRICTIONS AND LOCK-UP PERIOD ARE BINDING ON TRANSFEREES OF THESE SECURITIES.


 


4.            Lock-Up Period.
Purchaser hereby agrees that Purchaser shall not sell, offer, pledge, contract to sell, grant any option or contract to purchase,
purchase any option or contract to sell, giant any right or warrant to purchase, lend or otherwise transfer or encumber, directly
or indirectly, any Shares or other securities of the Company, nor shall Purchaser enter into any swap, hedging or other arrangement
that transfers to another, in whole or in part, any of the economic consequences of ownership of any Shares or other securities
of the Company, during the 180-day period (or such other shorter period as may be requested in writing by the managing underwriter
and agreed to in writing by the Company) following the effective date of the first registration statement of the Company filed
under the Securities Act that includes securities to be sold on behalf of the Company to the public in an underwritten public offering
under the Securities Act. Purchaser further agrees, if so requested by the Company or any representative of its underwriters, to
enter into such underwriter’s standard form of “lockup” or “market standoff” agreement in a form
satisfactory to the Company and such underwriter. The Company may impose stop-transfer instructions with respect to securities
subject to the foregoing restrictions until the end of such period.
