F1: On March 19, 2013, in connection with certain restricted stock units ("RSUs") received on March 15, 2013, which RSUs shall vest on the one year anniversary of the grant date, the Reporting Person filed a Form 4 (the "Original Form 4") to report an acquisition of 689 shares of Iron Mountain Incorporated common stock in Table I. Prior to the receipt of the grant of RSUs, however, the Reporting Person made an election to defer receipt of all restricted stock units awarded during 2013 pursuant to the Iron Mountain Incorporated Directors Deferred Compensation Plan. The Original Form 4, therefore, is being amended to reflect the receipt of the RSUs in Table II as shares of phantom stock. As of March 19, 2013, the Reporting Person owned 10,570 shares of Iron Mountain Incorporated common stock and 4,878 shares of phantom stock (the "Phantom Shares").

F2: Pursuant to the Reporting Person's election to participate in the Iron Mountain Incorporated Directors Deferred Compensation Plan with respect to the RSUs, the Phantom Shares become payable in Iron Mountain Incorporated common stock following the Reporting Person's disability or cessation of service as a director. Each Phantom Share is the economic equivalent of one share of common stock.
