Salesforce can terminate the naming rights agreement without penalty if there are no open retail tenants inside the center after it's been open for two years or if security staffing falls below a certain level. It can also break the deal with no penalty if either the rooftop park or bus service is closed for more than a year for reasons other than "force majeure," a legal term for an unforeseeable event. Salesforce can terminate the agreement without cause by paying an early termination fee equal to three years of fees, or around $10 million.
