On January 31, 2013, Iron Mountain Incorporated, or the Company, entered into an amendment, or the Second Amendment, to the Company's existing credit agreement, as previously amended, with certain lenders, JPMorgan Chase Bank, N.A., as administrative agent, and JPMorgan Chase Bank, N.A., Toronto Branch, as Canadian administrative agent, or the Credit Agreement. The Second Amendment reduces the minimum ratio of Adjusted EBITDA to Fixed Charges (as those terms are defined in the Credit Agreement) required to be maintained under Section 9.11 of the Credit Agreement. Giving effect to the Second Amendment, Section 9.11 of the Credit Agreement requires the Company to maintain a minimum ratio of Adjusted EBITDA to Fixed Charges of 1.00 to 1.00 at the end of any fiscal quarter ending during the period from January 1, 2013 through March 31, 2014 (for the period of four fiscal quarters then ended). After March 31, 2014, the minimum ratio reverts to 1.20 to 1.00.

Other than as it was specifically modified by the Second Amendment, the Credit Agreement remains in full force and effect.

The above description of the Second Amendment is not complete and is subject to and qualified in its entirety by reference to the Credit Agreement, a copy of which is attached as Exhibit 10.1 to our Quarterly Report on Form 10-Q for the quarter ended June 30, 2011, to the amendment to the Credit Agreement, a copy of which is attached as Exhibit 10.1 to our Quarterly Report on Form 10-Q for the quarter ended September 30, 2012, and to the Second Amendment, a copy of which is attached hereto as Exhibit 10.1, each of which is incorporated herein by reference.
