Changes to a contract after it is signed
I emailed a friend an executed copy of a legal agreement. I explined to here that I reserved the right to make changes to exhibit A & B. she signed the signature page of the contract and faxed it back to me. However, about a week later she emailed me and stated she will no longer negotiate and that any she is opting out of any existing agreements. She states that since I was going to make chnages to the initial contract she was not legally bound it it. Is this true? Why or why not?
