Why does the reseller have no ability to bind Wavelink to agreements, warranties or representations with or to a third party? (clause 3.1)

The Reseller may enter into sales agreements/contracts with third parties (customers) to sell the Products to customers. Wavelink are not a party to these agreements/contracts and are not contractually bound to such agreements/contracts and the Reseller cannot represent to the customers that Wavelink is bound. 

Wavelink can only be bound to the provisions in the Reseller Agreement.  

For example, if the Reseller sells 10 Products, but Wavelink only have 8 in stock, Wavelink are not bound by the Reseller’s sale (however clause 4.2 of the Reseller Agreement sets out that Wavelink must use good faith to fulfill all orders).
