Final answer:
Rico would be held responsible for the lease if Start-Up Games, Inc. fails to pay because he signed a personal guaranty of the lease's performance.
Step-by-step explanation:
If Rico is held responsible for paying the rent under this lease, it will be because Rico personally guaranteed the lease. By signing a document titled "GUARANTY" which states that it is "an absolute guaranty" of the lease's performance, Rico has agreed to be personally liable if Start-Up Games, Inc. fails to fulfill their leasing obligations. The guaranty ensures that the landlord, Tower Office Suites, has another party (Rico) to turn to for payment, should the company default on the rent.
