1.
Amendment of the Subscription Agreement. Section 2(d) of the Subscription Agreement shall be deleted in its entirety
and replaced with the following:


 


“(d)
Favored Nations Provision. For a period of two (2) years from the Closing Date, other than in connection with (i) full
or partial consideration in connection with a strategic merger, acquisition, consolidation or purchase of substantially all of
the securities or assets of a corporation or other entity which holders of such securities or debt are not at any time granted
registration rights equal to or greater than those granted to the Subscribers, (ii) the Company’s issuance of securities
in connection with strategic license agreements and other partnering arrangements so long as such issuances are not primarily
for the purpose of raising capital and which holders of such securities or debt are not at any time granted registration rights
equal to or greater than those granted to the Subscribers, (iii) the Company’s issuance of Common Stock or the issuances
or grants of options to purchase Common Stock to employees, and directors, pursuant to plans that have been approved by a majority
of the stockholders and a majority of the independent members of the board of directors of the Company or in existence as such
plans are constituted on the date of this Agreement, (iv) the Company’s issuance of securities upon the exercise or exchange
of or conversion of any securities exercisable or exchangeable for or convertible into shares of Common Stock issued and outstanding
on the date of this Agreement on the terms in effect on the Closing Date, (v) an issuance by the Company of securities resulting
from the exercise of Warrants or conversion of the Shares, (vi) the Company’s issuance of up to 450,000 shares of Common
Stock to its advisors pursuant the independent contractor agreements dated October 1, 2014, and (vii) any and all securities required
to be assumed by the Company by the terms thereof as a result of any of the foregoing even if issued by a predecessor acquired
in connection with a business combination, merger or share exchange (collectively, the foregoing (i) through (vii) are “Excepted
Issuances”), if at any time the Company shall issue any Common Stock or securities convertible into or exercisable for
shares of Common Stock (or modify any of the foregoing which may be outstanding) to any person or entity (including issuances
to service providers or consultants) at a price per share or conversion or exercise price per share which shall be less than $0.30
per share, being the per share price of the Shares hereunder (disregarding any value attributable to the Warrants) or as in effect
at such time, (the “Lower Price Issuance”), then the Company shall issue, subject to the Adjustment Limitation,
to the Subscribers such number of additional Units to reflect such lower price for the Shares such that the Subscribers shall
hold such number of Units, in total, had Subscribers paid a per Unit price equal to the Lower Price Issuance; provided further
the Company shall lower the Warrant exercise price to the price that is the product of: (i) one hundred and twenty five percent
(125%), and (ii) the issuance price of the Lower Price Issuance. Common Stock issued or issuable by the Company for no consideration
or for consideration that cannot be determined at the time of issue will be deemed issuable or to have been issued for $0.001
per share of Common Stock. The rights of Subscribers set forth in this Section 2 are in addition to any other rights the Subscribers
have pursuant to this Agreement, or the Warrants, and any other agreement referred to or entered into in connection herewith or
to which Subscribers and Company are parties. The Company shall be required to make one or many adjustments with respect to a
Lower Price Issuance provided that the provisions of this Section 2(d) remain in full force and effect. For purposes of this Section
2(d), all parties to this Agreement agree that the “Adjustment Limitation” limits the number of additional Units issuable
to a Subscriber pursuant to this Section 2(d) to that number of additional Units that would result in that Subscriber’s
beneficial ownership, along will all other shares of Common Stock beneficially owned by that Subscriber, to exceed 4.99% of the
outstanding shares of Common Stock and that the Warrant underlying such additional Units shall contain similar beneficial ownership
limitations on the exercise of such underlying Warrant.”


 


2.
Entitlements Under Section 2(d) As Amended. On execution of this Amendment, any and all remedies to which the Subscribers
may be entitled under Section 2(d), prior to this Amendment shall be subject to, limited by and solely in accordance with Section
2(d) as amended by this Amendment.


 






    			 



    	 	 	 



    

 


3.
Consideration for Amendment. On execution of this Amendment, the Company agrees to pay, on a pro-rata basis to all
subscribers that purchased Units in the Offering, and in proportion to the respective Units purchased by each subscriber, pursuant
to the Subscription Agreement, an aggregate $250,000 (“Payment”) upon the occurrence of the following events and in
the amounts and on payment dates set forth in connection with such events:


 


	 	(i)	in
    the event of a closing of any one or more equity or debt financing resulting in aggregate gross proceeds from the date of
    this Amendment of $350,000 or less, a payment towards the then-remaining Payment equal to ten-percent (10%) of such gross
    proceeds shall be made within three (3) business days of the closing of any such equity or debt financing; 
	 	 	 
	 	(ii)	in
    the event of a closing of any one or more equity or debt financing resulting in aggregate gross proceeds from the date of
    this Amendment of $350,000 or more but less than $1,000,000, a payment towards the then-remaining Payment equal to twenty-percent
    (20%) of such gross proceeds shall be made within three (3) business days of the closing of any such equity or debt financing;
	 	 	 
	 	(iii)	at
    any of the Company’s fiscal-year-ends payment will be made in the amount of available cash prior to any payments of
    bonuses payable to Mr. Allen, the Company’s CEO, CFO and Chairman, and Mr. Handerhan, the Company’s COO, Secretary
    and Director (collectively the “Officers”); and
	 	 	 
	 	(iv)	upon
    closing of any one or more equity or debt financing resulting in aggregate gross proceeds from the date of this Amendment
    of $1,000,000 or more, a payment of all then-remaining Payment within three (3) business days of the closing of any such equity
    or debt financing. 


 


Notwithstanding
anything contrary herein, the Company agrees that it shall not, and each Officer agrees to cause the Company not to, (i) pay each
of the Officers cash compensation, whether in base salary or bonus, in excess of $50,000 per year until such time as the Payment
has been fully satisfied, at which time any accrued and unpaid salaries or bonuses in excess of $50,000 per year per Officer may
be made in full or (ii) distribute or otherwise use the proceeds of any debt or equity financing until the payments required by
this Section 3 have been made.


 


4.

as amended by this Amendment.
