The proposed contract is one-sided for two reasons:
I) It is presented under racist patronizing threats;
The white man tries to convince the black man to sign the contract by making him fear for his safety in a world where he is no longer a slave. The white man treats the black man in a patronizing way, that is, acting like the black man couldn't protect himself, and also trying to make the black man fear for his life.
II) The majority of the production will go to the owner of the farm instead of the worker.
Besides signing the contract for fear, the black man would work and get only a small part of his work's production. On the entire next year it was going to be one-twentieth part, and that would later increase slowly. It was a blatant exploitation.
