This is right, but misleading. Consideration isn't the big question in this thread. It's whether or not a verbal agreement can be binding.
In some cases it can be, but a mere agreement to agree is not binding.
The biggest takehome is 'consult with legal before making promises or representations to counterparties".
Edited this a few times to keep it as short as possible without being misleading.
I am not a lawyer, either. Just an engineer with the minimum legal training required for licensure, which is basically, "know when you should ask for help."
