Company that it is registered with SAT (revenue system) as an individual with
commercial activities. After receiving the payments accordingly with this
clause, the Concession Holder will issue and deliver a fiscal invoice to the
Company.
 
The Company will have the option to put in effect its Exploitation Option at any
moment within the Option Period, in other words, at any moment while the Option

Non-breaching Party must notify the breach to the Breaching Party, in order for
