Question

Quizplus · Accepted Answer

A Force Majeure clause excuses one or both parties from performance of the contract due to unforeseeable circumstances beyond their control, such as natural disasters or war, not changes in circumstances that place an excessive burden on one party. The clause you're describing sounds more akin to a hardship clause or a clause allowing for renegotiation under certain conditions.
