nonpublic information, including, but not limited to the fact that the Offering is being made and the terms and conditions of this
Offering.

 

H.       Anti-Dilution
Protection. In the event that the Company consummates a sale of Common Stock for cash consideration (a “Financing”)
prior to January 1, 2018 (such applicable period, the “Anti-Dilution Period”), and the price per share
of such Common Stock shares sold in such Financing (the “Per Share Price”) is less than $0.15 per share
(the “Anti-Dilution Price”)(each as adjusted for stock splits, dividends, recapitalizations and the like),
the Subscriber who purchased Shares hereunder shall receive such additional number of Shares equal to (i) the aggregate Purchase
Price paid by the Subscriber, divided by (ii) the price that Common Stock was sold at in the Financing (or any subsequent Financing
where the Per Share Price is less than the prior Anti-Dilution Price), minus (iii) the total aggregate Shares issued to the Subscriber
at the time of his, her or its entry into this Agreement plus any additional Shares previously issued to the Subscriber pursuant
to the terms of this Section H. Each time that additional Shares are issued to the Subscriber under this Section H,
the “Anti-Dilution Price” shall be deemed to reset and equal the lowest Per Share Price for all Financings
to date through the Anti-Dilution Period, immediately after such applicable issuance of Shares. Notwithstanding the above, no Shares
will be issued to the Subscriber pursuant to this Section H and no anti-dilution rights hereunder will apply (i) upon the
exercise of any warrants, options or convertible securities granted, issued and outstanding on the date of this Agreement; (ii)
upon the grant or exercise of any stock or options which may hereafter be granted or exercised under any employee benefit plan,
stock option plan or restricted stock plan of the Company now existing or to be implemented in the future; (iii) upon the issuance
of any securities in connection with an acquisition by the Company; (iv) upon the issuance of any securities pursuant to a commitment
by the Company that has been previously disclosed prior to the date hereof; (v) in connection with any public offering of securities;
(vi) in connection with the sale, exercise or conversion of any convertible securities, warrants or options; or (vii) in connection
with the issuance of shares of Common Stock other than for cash consideration.

I.       Piggyback
Registration Rights. The Company covenants and agrees that if, at any time prior to the Registration Rights Expiration Date
(defined below), it proposes to file a registration statement with respect to any class of equity or equity-related securities
(other than in connection with an offering to the Company’s employees or in connection with an acquisition, merger or similar
transaction) under the Securities Act in a primary registration on behalf of the Company and/or in a secondary registration on
behalf of holders of such securities, and the registration form to be used may be used for the issuance or resale of the Shares,
the Company will either include the Shares in such registration statement or give prompt written notice to Subscriber of its intention
to file such registration statement and will offer to include in such registration statement, such number of Shares with respect
to which the Company has received written requests for inclusion therein within twenty (20) days after the giving of notice by
the Company (the “Piggyback Registration Rights”). The Subscriber shall also provide the Company customary
and reasonable representations and confirmations regarding the Shares held by the Subscriber, information relating to the beneficial
ownership of other securities of the Company held by such Subscriber, information regarding the persons with voting and dispositive
control over the Subscriber and such other information as the Company or its legal counsel may reasonably request. The Subscriber
acknowledges and understands that the Company shall not be required to include Shares in a registration statement relating solely
to an offering by the Company of securities for its own account if the managing underwriter or placement agent shall have advised
the Company in writing that the inclusion of such securities will have a material adverse effect upon the ability of the Company
to sell securities for its own account, and provided further that the Subscriber is not treated less favorably than others seeking
to have their securities included in such registration statement. Notwithstanding the obligations set forth above, if any Securities
and Exchange Commission guidance sets forth a limitation on the number of securities permitted to be registered on a particular
registration statement as a secondary offering, the number of Shares to be registered on such registration statement will be reduced
pro rata between the Subscriber (or other parties) whose securities are included in such registration statement. The “Registration
Rights Expiration Date” is January 1, 2018.

requested, or other evidence, the Company, as promptly as practicable, shall notify Investor that Investor may sell or otherwise

and applied against the principal of this Note.

 

12.       Waivers.

and all other notices or demands relative to this instrument.
