NOW,
THEREFORE, for and in consideration of the mutual covenants contained herein and for other valuable consideration, the receipt and sufficiency
of which are hereby acknowledged, the Parties hereto agree as follows:


 


1.       Defined
Terms. Capitalized terms used but not defined in this Agreement shall have the meaning given
to such capitalized terms in the Side Letters and the Extension Agreements.




    1


     


    

2.       True-Up
Provisions. The True-Up Provisions set forth in Section 5 of the Extension Agreements and set
forth in the Side Letters are hereby deleted in their entirety.


 


3.       Guaranteed
Return Provisions. The Guaranteed Return Provisions set forth in the Side Letters are hereby
deleted in their entirety.


 


4.       Ratification
of Side Letters and Extension Agreements. Except as provided herein, the terms and provisions
of the Side Letters and the Extension Agreements shall remain unchanged and shall remain in full force and effect.


 


5.       Entire
Agreement. This Agreement supersedes and merges all prior and contemporaneous promises, representations,
and agreements. No modification of this Agreement or of the Note Purchase Agreements, the Notes, the Side Letters, the Extension Agreements,
or any other document related thereto, or any waiver of rights under any of the foregoing, shall be effective unless made by supplemental
agreement, in writing, executed by the Investor and the Company. The Investor and the Company further agree that this Agreement may not
in any way be explained or supplemented by a prior, existing, or future course of dealings between the parties or by any prior, existing,
or future performance between the parties pursuant to this Agreement or otherwise.


 


6.       Notices.
Any notice or communication required or permitted hereunder or under the Note Purchase Agreements, the Side Letters, or the Extension
Agreements shall be given in writing and sent in the manner required under the Note Purchase Agreements.


 


7.       Counterparts.
This Agreement may be executed in any number of counterparts with the same effect as if all Parties hereto had signed the same document.
All such counterparts shall be construed together and shall constitute one instrument, but in making proof hereof it shall only be necessary
to produce one such counterpart. Fax or electronic copies of a document shall be deemed an original for all purposes.


 


8.       Severability.
If any covenant, condition, or provision herein contained is held to be invalid by final judgment of any court of competent jurisdiction,
the invalidity of such covenant, condition, or provision shall not in any way affect any other covenant, condition, or provision herein
contained.


 


9.       Representation
by Counsel. The Parties acknowledge and confirm that each of their respective attorneys have
participated jointly in the review and revision of this Agreement and that it has not been written solely by counsel for one Party. The
Parties hereto therefore stipulate and agree that the rule of construction to the effect that any ambiguities are to or may be resolved
against the drafting Party shall not be employed in the interpretation of this Agreement to favor either Party against the other.


 


10.     Governing
Law. This Agreement and the rights and duties of the parties hereunder shall be governed for
all purposes by the law of the State of Arizona and the law of the United States applicable to transactions within said State, without
giving effect to principles of conflicts of law.


 


11.     Successors
and Assigns. The terms and provisions hereof shall be binding upon and inure to the benefit
of the Parties hereto and their respective successors. This Agreement is not assignable by the Company.
