Parker, the owner of certain unimproved real estate in Chicago, employed Adams, a real estate agent, to sell the property for a price of $250,000 or more and agreed to pay Adams a commission of 6 percent for making a sale. Adams negotiated with Turner, who was interested in the property and willing to pay as much as $280,000 for it. Adams made an agreement with Turner that if Adams could obtain Parker's signature to a contract to sell the property to Turner for $250,000, Turner would pay Adams a bonus of $10,000. Adams prepared and Parker and Turner signed a contract for the sale of the property to Turner for $250,000. Turner refuses to pay Adams the $10,000 as promised. Parker refuses to pay Adams the 6 percent commission. In an action by Adams against Parker and Turner, what is the judgment?

In addition to answering this question, is this UCC or Common Law and why?!
