Credit Agreement

On April 16, 2007, Iron Mountain Incorporated (the “Company,” “we” or “us”) entered into a new credit agreement (the “New Credit Agreement”) to replace both its prior $750 million maximum principal amount revolving credit and term loan facilities and the ₤200 million maximum principal amount revolving credit and term loan facilities of its subsidiary, Iron Mountain Europe Limited. The New Credit Agreement provides for borrowings in an aggregate principal amount of up to $900 million, including revolving credit facilities in an aggregate amount of $600 million (including Canadian Dollar and multi-currency revolving credit facilities), and a $300 million term loan facility. We have the right to increase the aggregate amount available to be borrowed under the New Credit Agreement to up to $1,200 million. Our subsidiaries, Iron Mountain Canada Corporation and Iron Mountain Switzerland GmbH, may borrow directly under the Canadian revolving credit and multi-currency revolving credit facilities, respectively. Additional subsidiary borrowers may be added under the multi-currency revolving credit facility. The new revolving credit facilities terminate on April 16, 2012, at which point all revolving credit loans are due. With respect to the new term loan facility, quarterly loan payments of $0.75 million begin in the third quarter of 2007 and will continue through maturity on April 16, 2014, at which time the remaining outstanding principal balance of the term loan facility is due. The interest rate on borrowings under the New Credit Agreement varies depending on our choice of interest rate and currency options, plus an applicable margin. The Company guarantees the obligations of each of the subsidiary borrowers under the New Credit Agreement, and substantially all of the Company’s U.S. subsidiaries guaranty the obligations of the Company and the subsidiary borrowers. The capital stock or other equity interests of most of our U.S. subsidiaries, and up to 66% of the capital stock or other equity interests of our first tier foreign subsidiaries, are pledged to secure the New Credit Agreement, together with all intercompany obligations of foreign subsidiaries owed to us or to one of our U.S. subsidiary guarantors. The New Credit Agreement and the Acknowledgment, Confirmation and Amendment of Guarantee or Security Document, executed in connection with the New Credit Agreement, are set forth in Exhibits 10.1 and 10.2 attached hereto and incorporated by reference herein.
