If you presented the post-hoc changed contract as binding, I believe so. If you presented the post-hoc changed contract back to IBM and went "Hey, do you agree to an updated contract?" then you'd probably be laughed out of their office, but that's not a crime to ask them to update a contract.
You could make an intentionally vague reply saying; "Thanks! Here is the updated contract with my signature back.". Making the other party think you just updated the contract by adding your signature.
