Lol, that contract is a joke in how pathetic it's written. I mean it uses a patronizing language, deliberately tries to be confusing and ambiguous on certain terms, and clearly looks too unprofessionally written. Rule of thumb, corporations will try to screw you with contracts period. Analyze the contracts and make sure they explicitly state terms in a understandable way that (without loopholes, unfair conditions to invalidate these terms, etc added): You'll clearly be paid in some way that's satisfactory to both parties (make sure a figure you'll be paid and their conditions about payment(s), are printed on the contract), and you'll have sufficient or absolute intellectual property rights to all works you produce.
