When one side pulls out of a contract (for example in the case of Paula Deen's business deals), don't they still have to pay the other side and fulfill the contract?

Every day for the past week we’ve been hearing about another corporate entity that has severed their ties with Paula Deen. Walmart, Target, Ballantine Books, Smithfield Hams. I’m not using Food Network because if I’m not mistaken, they said they would not renew her contract so I don’t believe they’re a good example of what I’m talking about. For those that severed their involvement with Paula Deen, wouldn’t they still have to pay for the life of the contract?
