>Mora later sought to terminate his relationship with Giumarra, and he sold his nectarines to another fruit packer in 2023

The farmer sought termination and violated the contract.

ah, good catch. the question now is whether giumarra accepted the termination or not. i could not find that detail in the article. if they accepted it, then my argument holds (note that i am arguing how things should be, not what the actual current law on the matter is). if giumarra did not accept termination then the exclusive contract should still hold. (whether an exclusive contract is fair or not is another topic)
