     "This transition represents a natural evolution of the senior
 leadership at Iron Mountain. I have been discussing a succession plan with
 the Board and I feel that now is the appropriate time to implement it. Bob
 has been a leading candidate for the CEO position since he joined the
 Company in 2004," Reese said. "He has a strong background in technology and
 logistics and an excellent track record of building successful senior
 executive teams. Bob has proven himself as a strong leader within our
 Company and is committed to enhancing our culture and driving long-term
 success at Iron Mountain. I am confident that Bob's appointment as CEO will
 enhance our ability to pursue our strategic agenda."
     Brennan, 47, joined Iron Mountain as President of North America in
 November 2004 in connection with the Company's acquisition of Connected
 Corporation, where he served as Chairman and CEO. He was named President
 and Chief Operating Officer in December 2005. "Bob emerged as the leading
 candidate to fill this position shortly after joining the Company and has
 effectively been transitioning into this role for the past two years,"
 continued Reese. "He has all the characteristics the Board and I were
 looking for in Iron Mountain's next CEO. He has learned the business very
 quickly from the inside, he's a great leader who cares deeply about the
 employees and customers and he always 'flies the mission.'"
     "I have tremendous respect for what Richard and the Iron Mountain team
 have built over the last 26 years," said Brennan. "We have become vital to
 businesses as they wrestle with the overwhelming task of compliant records
 management in a world of exploding information and escalating regulation.
 This is a great business, and Iron Mountain is uniquely positioned to
 capture the tremendous opportunity in the market today. I am very excited
 at the prospect of leading this Company through the next phase of its
 growth and development and I look forward to continuing my partnership with
 Richard as he assumes his new role in the Company."
     As Executive Chairman, a full time position reporting to the Board,
 Reese, 61, will focus on driving the Company's new services agenda and
 advising the CEO on strategy and other matters of the business while
 continuing to perform his duties as Chairman of the Company's Board of
