of Laurie A. Tucker</font></u></p>

<p style="margin-bottom:12.0pt;margin-left:0pt;margin-right:0pt;text-indent:36.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">On
March 2, 2007, Iron Mountain Incorporated&#146;s (the &#147;Company&#148;) Board of Directors
(the &#147;Board&#148;) expanded the size of the Board by one member, from seven to
eight, and elected Laurie A. Tucker, Senior Vice President of Marketing at
FedEx Corporate Services, Inc. (&#147;FedEx&#148;), as a member of the Board.&#160; At the same meeting, the Board elected Ms.
Tucker to the Nominating and Governance Committee of the Board.</font></p>

<p style="margin-left:0pt;margin-right:0pt;text-indent:36.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Ms. Tucker joined FedEx in
1978 as a financial analyst and since then, has gained experience across many
facets of the business.&#160; Today, Ms.
Tucker is responsible for developing marketing strategy, product research and
development, brand management, advertising, retail, sponsorship marketing,
business alliances, e-commerce, and customer experience management.&#160; Also active in the community, Ms. Tucker is
on the Board of Visitors of the University of Memphis, which is where she
earned both her B.A. and M.B.A.&#160; She is
also the FedEx co-chair for the March of Dimes and has been a United Way Alexis
de Tocqueville Society member since 1998.</font></p>

<p style="margin:0pt 0pt 12.0pt;text-indent:36.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Upon her election, Ms. Tucker received an option to purchase 1,683
shares of the Company&#146;s common stock at an exercise price of $27.18 per share
(equal to the fair market value of the common stock on March 2, 2007, as
calculated in accordance with the option plan).&#160;
This option will fully vest on March 2, 2008.&#160; Ms. Tucker will be compensated for her
service on the Board in accordance with the Company&#146;s Compensation Plan for
Non-Employee Directors.</font></p>

<p style="margin:0pt 0pt 12.0pt;text-indent:36.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Ms. Tucker has no family
relationships with any director or executive officer of the Company, and there
are no transactions in which Ms. Tucker has an interest requiring disclosure
under Item 404(a) of Regulation S-K.</font></p>

<p style="margin:0pt 0pt 12.0pt;"><b><font size="2" face="Times New Roman" style="font-size:10.0pt;font-weight:bold;">Item 7.01. Regulation FD Disclosure.</font></b></p>

<p style="margin:0pt 0pt 12.0pt;text-indent:36.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">On March 5, 2007, we announced a proposed offering of C$175 million in
aggregate principal amount of CAD Senior Subordinated Notes due 2019 by our
wholly owned subsidiary, Iron Mountain Nova Scotia Funding Company. The notes
will be fully and unconditionally guaranteed by the Company and certain of its
wholly owned subsidiaries. The notes are being offered only to qualified
institutional buyers under Rule 144A and to persons outside the United States
pursuant to Regulation S. The securities to be offered have not been registered
under the Securities Act of 1933, as amended, or applicable securities laws, and
until so registered, may not be offered or sold in the United States except
pursuant to an exemption from the registration requirements of the Securities
Act and applicable state securities laws. This Current Report on Form 8-K shall
not constitute an offer to sell or a solicitation of an offer to buy any
securities.</font></p>

<p style="margin:0pt 0pt 12.0pt;text-indent:36.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">In the offering memorandum relating to our offering of the notes, we
disclosed that we expect to enter into new amended and restated term loan and
revolving credit facilities in the second quarter of 2007 to replace the
Company&#146;s existing term loan and revolving credit facilities.&#160; We expect that advances under the Company&#146;s
new amended and restated term loan and revolving credit facilities will be used
to repay in full existing term loan and revolving credit facilities of Iron
Mountain Europe Limited.</font></p>
