outstanding Registrable Securities of such Holders having an anticipated aggregate offering

proceeds, net of Selling Expenses, of at least fifty million US dollars ($50,000,000), then

Notice to all Holders other than the Initiating Holders; and (ii) as soon as practicable, and in

any event within forty-five (45) days after the date such request is given by the Initiating

Holders, file a Form S-3 registration statement under the Securities Act (or a post-effective

amendment or prospectus supplement to an existing Form S-3 registration statement)

covering all Registrable Securities requested to be included in such registration by any other

Holders, as specified by notice given by each such Holder to PubCo within twenty (20) days

of the date the Demand Notice is given, and in each case, subject to the limitations of

paragraphs b(i)(3) and b(iii) of this Agreement. Such Form S-3 registration statement may

with, the laws of the State of Nevada, without regard to its rules of conflict of laws

that would result in the application of the laws of another jurisdiction.

6.This Amendment, together with the other documents and agreements referred to

herein, is the entire, final, and complete agreement and understanding of the Parties

hereto relating to the subject matter hereof and supersedes and replaces all prior and

contemporaneous agreements and understandings, whether written and oral, by and

among the Parties or their representatives with respect thereto.

7.This Amendment may be executed in two or more counterparts, each of which shall

be deemed an original, but all of which together shall constitute one and the same
