Whenever you elect to terminate the other party for cause or for default, you need to JUSTIFY the basis of the cause or default. The reason being is that a termination for default or cause is the harshest contractual remedy. This is why the other party will typically either (i) convert the termination for default into one for convenience, or (ii) if there is no termination for convenience provision in the contract, argue the terminating party breached the contract by terminating the contract without rightful justification.

The key is if you are going to terminate a party for cause of default, make sure you have memorialized the persuasive reasons for exercising the termination, and can otherwise reasonably support the justification. Do not, and I repeat, do not haphazardly exercise a termination for default and think you do not have to justify the basis for the termination.
