Iron Mountain Incorporated (the “Company”) entered into an Employment Agreement dated August 11, 2008 with Robert Brennan, the Company’s Chief Executive Officer (the “Agreement”).

Pursuant to the Agreement, Mr. Brennan will serve as the Company’s Chief Executive Officer and will receive an annual salary of $900,000.00 (the “Base Salary”).  Mr. Brennan will be eligible to earn an annual bonus in accordance with the terms and conditions of the Iron Mountain Incorporated 2006 Senior Executive Incentive Plan (the “SEIP”).  In addition, Mr. Brennan will be eligible to earn a one-time special bonus for 2008 in the target amount of twenty-five percent (25%) of his Base Salary for 2008 and prorated based on his assuming the role of Chief Executive Officer on June 5, 2008.  The Compensation Committee of the Board shall determine the amount of such bonus in its sole discretion.

If Mr. Brennan’s employment is terminated for any reason, he will be entitled to the following items that were earned and accrued but unpaid as of the date of termination: (i) Base Salary; (ii) cash payment for all accrued, unused vacation time; (iii) reimbursement for business expenses and (iv) such other benefits to which Mr. Brennan may be entitled by law or pursuant to a benefit plan of the Company.

If Mr. Brennan is terminated without Cause or terminates his employment for Good Reason, in addition to the payments described above, Mr. Brennan will receive (i) payments equaling one (1) year of his most recent Base Salary; (ii) health, dental and vision coverage for himself and his dependents until the earlier of 2 years or the date he becomes eligible for alternate coverage and (iii) a bonus for the year in which the termination occurs equal to the average bonus paid under the SEIP in the two (2) years preceding his termination.

The SEIP was filed as Appendix C to the Company’s Proxy Statement for the 2008 Annual Meeting of Stockholders, which was filed with the Securities and Exchange Commission on April 21, 2008.  The terms “Cause” and “Good Reason” are defined in the Agreement.  The foregoing summary of the Agreement is qualified in its entirety by reference to the Agreement, a copy of which is filed as Exhibit 10.1 to this Current Report on Form 8-K and incorporated herein by reference.
