sold pursuant to an exemption from registration contained in the Securities Act based in part upon such Purchaser’s representations
contained in this Agreement. Such Purchaser hereby represents and warrants, solely as to such Purchaser, as follows:

(i) Purchaser Bears Economic Risk. Such Purchaser is
an investor in securities of companies that are thinly traded on the OTC Markets and qualify as
a “smaller reporting company,” as defined in Item 10(f)(1) of Regulation S-K, that chooses to prepare the disclosure
in the SEC Documents relying on scaled disclosure requirements for smaller reporting companies in Regulation S-K and in Article 8
of Regulation S-X, and such Purchaser acknowledges that it is able to fend for itself, can bear the economic risk of the transactions
contemplated by this Agreement and any investment in the Shares, and has such knowledge and experience in financial or business matters
that it is capable of evaluating the merits and risks of the transactions contemplated by this Agreement, including any investment in
the Shares. Such Purchaser acknowledges that this Agreement and any acquisition of Shares involves a high degree of risk, and represents
that it is able, without materially impairing its financial condition, to undertake the transactions contemplated by this Agreement and
hold any Shares for an indefinite period of time and to suffer a complete loss of its investment.

(ii) Acquisition for Own Account. Such Purchaser is
acquiring the Shares for investment for such Purchaser’s own account not as a nominee or agent, and not with a view to the resale
or distribution of any part thereof, and such Purchaser has no present intention of selling, granting any participation in, or otherwise
distributing the same and such Purchaser does not have any contract, undertaking, agreement or arrangement with any person to sell, transfer
or grant participations to such person or to any third person, with respect to the foregoing.

(iii) Purchaser Can Protect Its Interest. Such Purchaser
represents that by reason of its, or of its management’s, business or financial experience, such Purchaser has the capacity to protect
its own interests in connection with the transactions contemplated in this Agreement. Further, such Purchaser is aware of no publication
of any advertisement in connection with the transactions contemplated in this Agreement.

 

    	 

    	 

    

 

(iv) Accredited Investor. Such
Purchaser is an “accredited investor” within the meaning of SEC Rule 501 of Regulation D, as presently in effect.

(v) Company Information. Such Purchaser has received and
read the SEC Documents, including the Company’s financial statements, and has had an opportunity to discuss the Company’s
business, management and financial affairs with directors, officers and management of the Company and has had the opportunity to review
the Company’s operations and facilities. Such Purchaser has also had the opportunity to ask questions of and receive answers from,
the Company and its management regarding the terms and conditions of this investment. The foregoing does not modify the representations
and warranties of the Company set forth in Section 3 of this Agreement or the right of the Purchasers to rely thereon.

(vi) Rule 144. Such Purchaser acknowledges and agrees
that the Shares are “restricted securities” as defined in Rule 144 promulgated under the Securities Act as in effect from
time to time and must be held indefinitely unless they are subsequently registered under the Securities Act or an exemption from such
registration is available. Such Purchaser has been advised or is aware of the provisions of Rule 144, which permits limited resale of
securities subscribed for in a private placement subject to the satisfaction of certain conditions, including, among other things: the
availability of certain current public information about the Company, the resale occurring following the required holding period under
Rule 144 and the number of securities being sold during any three-month period not exceeding specified limitations.

(vii) Residence. If such Purchaser is an individual,
then such Purchaser resides in the state or province identified in the address of such Purchaser set forth on the signature pages hereto;
if such Purchaser is a partnership, corporation, limited liability company or other entity, then the office or offices of such Purchaser
in which its principal place of business is identified in the address or addresses of such Purchaser set forth on the signature pages
hereto.

(c) Transfer Restrictions. Purchasers acknowledge and
agree that:

(i) the Shares may only be disposed
of in compliance with state and federal securities laws. In connection with any transfer of Shares other than pursuant to an effective
registration statement, to the Company or to an affiliate (as such terms are used in and construed under Rule 405 under the Securities
Act) of a Purchaser, the Company may require the transferor thereof to provide to the Company an opinion of counsel selected by the transferor
and reasonably acceptable to the Company, the form and substance of which opinion shall be reasonably satisfactory to the Company, to
the effect that such transfer does not require registration of such transferred Securities under the Securities Act. As a condition of
transfer, any such transferee shall agree in writing to be bound by the terms of this Agreement and the Registration Rights Agreement
(as defined below) and shall have the rights and obligations of a Purchaser under this Agreement and the Registration Rights Agreement.

(ii) so long as is required by this Section 4.2(c), a legend
shall be imprinted on any of the Shares in the following form:

THIS SECURITY HAS NOT BEEN REGISTERED
WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION
UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT
TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT
TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS.

(iii) Certificates evidencing the Shares
shall not contain any legend (including the legend set forth in Section 4.2(c)(ii) hereof), (a) while a registration statement (including
the Registration Statements (as defined in the Registration Rights Agreement)) covering the resale of such security is effective under
the Securities Act, (b) following any sale of such Shares pursuant to Rule 144, (c) if such

    	 

    	 

    

 

Shares are eligible for sale under Rule
144 without the need to comply with the current information requirement contained in Rule 144(c), or (d) if such legend is not required
under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the
SEC). The Company shall cause its counsel to issue a legal opinion to its transfer agent or the Purchaser if required by the transfer
agent to effect the removal of the legend hereunder, or if requested by a Purchaser, respectively.
