Inc., a Nevada corporation, formerly known as Mega Bridge Inc. (the "Company"), and certain warrant holders of
the Company which are named on the signature page to this Agreement (together, the "Amending Parties"), with
respect to the following facts:


A.
On or about June 28, 2017, the Company entered into an Asset Assignment Agreement (the “Assignment Agreement”)
with Richard L. Chang Holding’s, LLC, a Nevada limited liability company (“Holdings LLC”), pursuant
to which Holdings LLC contributed certain Patent Assets to the Company with the expectation that the Company would raise sufficient
capital to develop the Patent Assets;


B.
Pursuant to the Assignment Agreement, Holdings LLC has a right of reversion to receive the Patent Assets back from the Company
in the event that the Company failed to raise a minimum of $1,000,000 in equity financing on or before June 28, 2018, and the
Company has failed to raise the equity;


C.
Holdings LLC has agreed to waive the right of reversion under the Assignment Agreement provided that (i) the Amending Parties
agree to amend the Common Stock Purchase Warranted dated June 28, 2017 (the “Warrant”) issued to each of them
to reduce the number of warrant shares; and (ii) the Company raises a minimum of $1,000,000 in equity financing on or before June
28, 2019.


D.
The Amending Parties are entering into this Agreement to, among other things, induce Holdings LLC to waive the right of reversion
