The big problem is what happens if the agreement is not kept? If it said the lease terminates, Linn might be in trouble, if all you can do on the other hand is sue for damages, how big are your damages? I would make me unhappy too and I would voice my displeasure and Linn had better never need anything from me in the future but only you can decide if they made you unhappy enough for you to spend money on a lawsuit just to show your displeasure.
