On May 25, 2012, DC-19675 W. Ten Mile, LLC, a wholly-owned subsidiary of CVOP, in connection with the acquisition of 100% of the fee simple interest in an approximately 53,000 square foot data center (the “Southfield Property”), located in Southfield, Michigan, entered into a joinder agreement, dated May 25, 2012, and executed a mortgage and an assignment of lease and rents, dated May 25, 2012, each with KeyBank, which increased CVOP’s availability under the secured revolving credit facility by approximately $3,988,000.
