body: Suppose I have a firm named Blue. I signed a contract with a firm, named Green, to manage our fleet of motorcycles. The contract states "Green shall solicit and negotiate contracts with qualified independent contractors approved by Blue owners for repairs to the property motorcycles".
  
  
  Does that statement prevent our firm, Blue, from contacting and negotiating contracts directly with contractors to repair our motorcycles?
  
  
  
title: Does "shall" in a contract preclude the other party from performing a task?
