Only whole shares of Common Stock were transferred in-kind; fractional shares were sold and settled in cash. (F2) Pursuant to the Reporting Person's election to participate in the Iron Mountain Incorporated Directors Deferred Compensation Plan (the "Plan"), the Phantom Shares will become payable in shares of Common Stock on various dates selected by the Reporting Person or as otherwise provided in the Plan. Each Phantom Share is the economic equivalent of one share of Common Stock.
