Ethics of administrative guidance: how much is too much?

A younger vascular surgeon has been recruited to start a new program at a suburban hospital outside of a large city hosting a world-class medical center. The new program will provide state-of-the-art equipment, including robotics, free office space, and a generous salary guarantee. Dr Ready obtained a license in the state where he is relocating and is preparing to move. He is an excellent technical surgeon but is uncomfortable with complex aneurysm surgery. This morning he went to sign a contract with the hospital and found that a clause that prevents him from referring patients to physicians outside the hospital in strong legalese is included. How should he proceed?
