Item 8.01 Other Events.

On August 18, 2009, C. Richard Reese, a director and the Executive Chairman of Iron Mountain Incorporated (the “Company”), adopted a stock trading plan (the “Reese 10b5-1 Plan”). On August 20, 2009, John Clancy, President, Iron Mountain Digital, adopted an unrelated stock trading plan (the “Clancy 10b5-1 Plan”). Both the Reese 10b5-1 Plan and the Clancy 10b5-1 Plan were adopted in accordance with Rule 10b5-1 under the Securities Exchange Act of 1934, as amended (“Rule 10b5-1”). Under Rule 10b5-1, directors, officers and other employees who are not in possession of material non-public information may adopt a pre-arranged plan or contract for the sale of Company securities under specified conditions and at specified times.

The Reese 10b5-1 Plan is an agreement between Mr. Reese and a broker to sell shares of common stock of the Company (“Common Stock”) that he owns. Currently, Mr. Reese beneficially owns 5,197,773 shares of Common Stock. Pursuant to the Reese 10b5-1 Plan, a maximum of 840,000 shares of Common Stock may be sold beginning on August 21, 2009 until the 10b5-1 Plan expires on July 31, 2010. The Reese 10b5-1 Plan specifies the number of shares of Common Stock that may be sold at predetermined prices, subject to the terms and conditions of the Reese 10b5-1 Plan.

The Clancy 10b5-1 Plan is an agreement between Mr. Clancy and a broker to sell shares of Common Stock that he owns as well as exercise Company options (“Options”) that he owns and sell the underlying shares of Common Stock of the Company. Currently, Mr. Clancy beneficially owns 134,512 shares of Common Stock. Pursuant to the Clancy 10b5-1 Plan, a maximum of 43,899 shares of Common Stock held by Mr. Clancy, including shares issued upon exercise of Options may be sold beginning on August 21, 2009 until the Clancy 10b5-1 Plan expires on November 20, 2009. The Clancy 10b5-1 Plan specifies the number of Options that may be exercised and shares of Common Stock that may be sold at predetermined prices, subject to the terms and conditions of the Clancy 10b5-1 Plan.

Each of Mr. Reese and Mr. Clancy independently entered into his respective Rule 10b5-1 plan as part of his personal long-term investment strategy for asset diversification and liquidity, and neither will have control over the timing of the sales of shares of Common Stock or exercise of Options, as applicable, under the Reese 10b5-1 Plan or Clancy 10b5-1 Plan.

Transactions under the Reese 10b5-1 Plan or Clancy 10b5-1 Plan will be reported to the Securities and Exchange Commission in accordance with applicable securities laws, rules and regulations. The Company does not undertake to report Rule 10b5-1 plans that may be adopted by any officers or directors in the future, or to report any modifications or termination of any publicly announced trading plan, except to the extent required by law.
