On September 18, 2014, Iron Mountain Europe PLC, or the Issuer, a wholly owned subsidiary of Iron Mountain Incorporated, or the Company, completed a private offering of £400.0 million in aggregate principal amount of 6.125% GBP Senior Notes due 2022, or the Notes. The Notes were sold at 100.0% of par. The net proceeds from the offering were approximately £393.4, after paying initial purchasers’ discounts and commissions and expenses. The net proceeds from the offering were used to repay amounts outstanding under the Company’s revolving credit facility and for general corporate purposes.

The Notes were offered and sold only to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended, or the Securities Act, and outside the United States pursuant to Regulation S under the Securities Act. The Notes have not been registered under the Securities Act or under any state securities law, and may not be offered or sold in the United States absent registration or an applicable exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and applicable state securities laws.

The Notes were issued under a Senior Indenture, dated as of September 18, 2014, or the Indenture , by and among the Issuer, the Company, the guarantors named therein, Wells Fargo Bank, National Association, as trustee, and Société Générale Bank & Trust, as paying agent, registrar and transfer agent.

The Issuer will pay 6.125% interest per annum on the principal amount of the Notes, payable semi-annually on March 15 and September 15 of each year. Interest will accrue on the Notes from September 18, 2014, and the first interest payment date will be March 15, 2015. The Notes will mature on September 15, 2022, unless earlier redeemed or repurchased.

The Notes are jointly and severally guaranteed on an unsecured senior basis by the Company and substantially all of the Company’s direct and indirect wholly owned domestic subsidiaries, or the Subsidiary Guarantors. The Notes and the guarantees will be the Issuer’s, the Company’s and the Subsidiary Guarantors’ general unsecured senior obligations, will be pari passu in right of payment with all of the Issuer’s, the Company’s and the Subsidiary Guarantors’ existing and future senior debt and will rank senior in right of payment to all of the Issuer’s, the Company’s and the Subsidiary Guarantors’ existing and future subordinated debt. The Notes are effectively subordinated to the Issuer’s, the Company’s and the Subsidiary Guarantors’ secured indebtedness to the extent of the value of the collateral securing such indebtedness and structurally subordinated to all liabilities of the Company’s subsidiaries that do not guarantee the Notes.

Prior to September 15, 2017, the Issuer may, at its option, redeem all or a portion of the Notes at the make-whole price set forth in the Indenture. Prior to September 15, 2017, the Issuer may, at its option, redeem the Notes with the net proceeds of certain equity offerings at the redemption price set forth in the Indenture so long as at least £260.0 million in aggregate principal amount of the Notes remains outstanding immediately afterwards. The Issuer has the option to redeem all or a portion of the Notes at any time on or after September 15, 2017 at the redemption prices set forth in the Indenture. Upon the sale of certain assets or upon certain changes of control, the Issuer may be required to offer to repurchase the Notes under the terms set forth in the Indenture.

The Indenture provides for customary “events of default” which could cause, or permit, the acceleration of the Notes and which are similar to those applicable to the Company’s currently outstanding senior 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 currently outstanding senior notes.

This brief description of the Notes is qualified in its entirety by reference to the Indenture, attached hereto as Exhibit 4.1, which is incorporated herein by reference.

This Current Report on Form 8-K shall not constitute an offer to sell or the solicitation of an offer to buy securities, nor shall there be any sale of these securities in any state or other jurisdiction in which such offer,

solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or jurisdiction.

Item 9.01.                                        Financial Statements and Exhibits.

4.1                               Senior Indenture, dated as of September 18, 2014, among the Issuer, the Company, the Subsidiary Guarantors, Wells Fargo Bank, National Association, as trustee, and Société Générale Bank & Trust, as paying agent, registrar and transfer agent. (Filed herewith.)
