	2.	Integration; Modification. This Amendment contains the entire understanding between NAI on the one hand, and MANNATECH US and MANNATECH SWISS on the other hand,
with respect to the subject matter of this Amendment and this Amendment supersedes all prior or contemporaneous oral or written agreements, conditions, or representations. This Amendment may not be amended, canceled, or superseded, nor will any
provision of this Amendment be deemed waived, except by a written instrument executed by each of the parties to be charged. 

  

	3.	Binding Effect. This Amendment will be binding upon, and inure to the benefit of, the parties and their respective heirs, legatees, personal representatives,
successors and assigns. 

  

	4.	Counterparts. This Amendment may be executed in one or more counterparts, each of which will be deemed an original, but all of which, when taken together, will
