(1)	This report reflects shares received by the Reporting Person as a result of the Reporting Person's receipt of his pro rata portion of a special dividend declared by the Board of Directors of the issuer on October 11, 2012 and paid on November 21, 2012 (the "Special Dividend").
(2)	Includes 376 previously unreported unvested shares of phantom stock (the "Phantom Shares") allocated on November 21, 2012 in connection with the Special Dividend. The Phantom Shares become payable in Iron Mountain Incorporated common stock following Mr. Verrecchia's disability or cessation of service as a director, pursuant to Verrecchia's election to participate in the Iron Mountain Incorporated Directors Deferred Compensation Plan with respect to certain restricted stock units ("RSUs") received on June 14, 2012, which RSUs shall vest on the one year anniversary of the grant date (or, if earlier, the annual meeting of stockholders that is closest to the one year anniversary). Each Phantom Share is the economic equivalent of one share of common stock.
