Item 2.03.     Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

On September 23, 2011, Iron Mountain Incorporated, or the Company, completed its offering of $400,000,000 in aggregate principal amount of its 7-3/4% Senior Subordinated Notes due 2019 (the “Notes”) pursuant to, and subject to the terms and conditions set forth in, an Underwriting Agreement, dated as of September 20, 2011, among the Company, the Guarantors named therein, and J.P. Morgan Securities LLC, Morgan Stanley & Co. LLC, Barclays Capital Inc., Merrill Lynch, Pierce, Fenner & Smith Incorporated, HSBC Securities (USA) Inc., RBS Securities Inc. and Scotia Capital (USA) Inc., as underwriters. The Notes were issued under a Senior Subordinated Indenture, dated as of September 23, 2011 (the “Base Indenture”), as supplemented by the First Supplemental Indenture (as so supplemented, the “Indenture”), dated as of September 23, 2011, by and among the Company, the Guarantors named therein and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Supplemental Indenture”).   The description of the Notes in this report is a summary and is qualified in its entirety by reference to the full text of the Indenture and the form of note included therein. A copy of the Base Indenture is attached hereto as Exhibit 4.1 and a copy of the Supplemental Indenture is attached hereto as Exhibit 4.2, both of which are incorporated herein by reference.

The Company will pay 7-3/4% interest per annum on the principal amount of the Notes, payable semi-annually on October 1 and April 1 of each year. Interest will accrue from September 23, 2011, and the first interest payment date will be April 1, 2012. The Notes will mature on October 1, 2019, unless earlier redeemed or repurchased. The Notes were issued at a price to the public of 100.0% of par.

The Notes are guaranteed on a senior subordinated basis by substantially all of the Company’s direct and indirect wholly owned domestic subsidiaries. The Notes and the subsidiary guarantees rank behind all of the Company’s and its subsidiary guarantors’ current and future senior indebtedness and equally with the Company’s and its subsidiary guarantors’ current and future senior subordinated indebtedness and trade payables.

The Company may, at its option, redeem some or all of the Notes at any time prior to October 1, 2015 at the make-whole price set forth in the Indenture and at any time on or after October 1, 2015 at the prices set forth in the Indenture. Prior to October 1, 2014, the Company may redeem a portion of the outstanding Notes with the proceeds of certain equity offerings as long as at least $260.0 million in aggregate principal amount of Notes remains outstanding immediately afterwards. If the Company sells certain assets or experiences specific kinds of changes in control, it must offer to repurchase the Notes at the prices set forth in the Indenture.

The Indenture provides for customary “events of default” which could cause, or permit, the acceleration of the Notes.  Those are similar to the events of default with respect to the Company’s other senior subordinated notes.  Under the terms of the Indenture the Company is also subject to financial covenants and restrictions which are substantially similar to those applicable to the Company’s other senior subordinated notes.
