Item 5.02.  Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On September 11, 2009, Iron Mountain Incorporated’s (the “Company”) Board of Directors (the “Board”) expanded the size of the Board by one member, from nine to ten, and elected Per-Kristian Halvorsen as a member of the Board.

Mr. Halvorsen is a senior vice president and serves as the chief innovation officer of Intuit Inc. (“Intuit”), a position he has held since December 2008. Previously, he was Intuit’s chief technology innovation officer and chief technology officer. Prior to Intuit, Mr. Halvorsen was vice president and center director of solutions and services for Hewlett Packard where, from 2000 to 2005, he oversaw global research and advanced technology for its IT services division. Mr. Halvorsen was principal scientist at Xerox Palo Alto Research Center, where he worked for 17 years and founded the Information Sciences and Technologies Lab. He is a director of Autodesk Inc. and Finn Corporation. Mr. Halvorsen holds a Ph.D. and M.A. from the University of Texas at Austin.

For his service as a director, Mr. Halvorsen will be entitled to the compensation the Company generally provides to its non-employee directors. A summary of our currently-effective director compensation is filed as Exhibit 10.24 to the Company’s Annual Report on Form 10-K for the year ended December 31, 2007.   He will also be able to participate in the Company’s Director Deferred Compensation Plan.  Upon his election, Mr. Halvorsen received an option to purchase 5,142 shares of the Company’s common stock at an exercise price of $28.365 per share (equal to the fair market value of the common stock on September 11, 2009, as calculated in accordance with the option plan).  This option will vest on the one year anniversary of the grant (or, if earlier, the annual meeting of Iron Mountain Incorporated that is closest to the one year anniversary).

Mr. Halvorsen has no family relationships with any director or executive officer of the Company, and there are no transactions in which Mr. Halvorsen has an interest requiring disclosure under Item 404(a) of Regulation S-K.
