Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) This Amendment is being filed to correct (i) the number of shares acquired by the Reporting Person reflected in column 5 of this Form 4, (ii) the amount of underlying securities reflected in column 7 of this Form 4 and (iii) the total shares of phantom stock beneficially owned by the Reporting Person reflected in column 9 of this Form 4. The line item is being included in this filing merely to gain access to the EDGAR filing system, not to report a new transaction.
(2) Pursuant to Mr. Ryan's election to participate in the Iron Mountain Incorporated Directors Deferred Compensation Plan (the "Plan"), the shares of phantom stock become payable in shares of common stock following Mr. Ryan's disability or cessation of service as a director. Each share of phantom stock is the economic equivalent of one share of common stock.
(3) The number of shares of phantom stock acquired by the Reporting Person on July 5, 2012 was reported as 650 shares rather than 659.946 shares due to an administrative error just corrected by New York Life Investment Management LLC, the record-keeper for the Plan.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.

Potential persons who are to respond to the collection of information contained in this form are not required to respond unless the form displays a currently valid OMB number.
