<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
offering size disclosed in the preliminary prospectus supplement dated January&nbsp;9, 2007 (the "Preliminary Prospectus Supplement") was &euro;175.0&nbsp;million,
rather than the &euro;225.0&nbsp;million we are issuing. We intend to use the additional &euro;47.0&nbsp;million in net proceeds we will receive from the offering to repay
amounts outstanding on our Iron Mountain term loan facility. As a result, and giving pro forma effect to the other transactions described in "Capitalization" on page S-18 in the
Preliminary Prospectus Supplement, we would have had $203,572 (in thousands) outstanding on our Iron Mountain term loan facility, rather than $263,221 (in thousands) disclosed in the "As Adjusted"
column on page S-18 of the Preliminary Prospectus Supplement. Our Iron Mountain term loans are senior to the notes. No other amount will change in the "As Adjusted" column on page
S-18 in the Preliminary Prospectus Supplement as a result of the increase in the notes being issued, except that (1)&nbsp;the amount outstanding of the 6<SUP>3</SUP>/<SMALL>4</SMALL>% Euro Senior
Subordinated Notes due 2018 increased from $259,919 to $320,476, (2)&nbsp;Total Long-Term Debt increased from $2,658,733 to $2,659,641, (3)&nbsp;Total Shareholders' </FONT></P>

decreased from $1,503,305 to $1,503,093, and (4)&nbsp;Total Capitalization increased from $4,162,038 to $4,162,734 (each dollar amount in clauses (1) to (4) of this sentence in thousands). </FONT></P>


<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
addition, giving pro forma effect to this offering and the other transactions described in "Capitalization" on page S-18 in the Preliminary Prospectus Supplement,
(1)&nbsp;the notes would have been subordinated to $232.5&nbsp;million of our and our subsidiary guarantor indebtedness; and (2)&nbsp;the notes would have ranked equally with
$1,947.4&nbsp;million (includes $2.5&nbsp;million of net premiums) of our and our subsidiary guarantor's other senior subordinated debt and trade payables. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
last sentence on page S-12 of the Preliminary Prospectus Supplement is hereby replaced in its entirety with the following: "Our existing term loans and credit facilities
would permit additional borrowings, under such facilities (subject to customary borrowing conditions) or otherwise, of up to $219.8&nbsp;million as of September&nbsp;30, 2006 assuming we had
completed our October&nbsp;2006 offering and this offering on September&nbsp;30, 2006 and applied the net proceeds from these offerings as described under "Capitalization." Additional borrowings
under such facilities would be, and other borrowings could be, senior to the notes and the subsidiary guarantees." </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
connection with the sale of the notes, Bear, Stearns International Limited (the "Stabilizing Manager") (or persons acting on behalf of the Stabilizing Manager) may
over-allot notes or effect transactions with a view to supporting the market price of the notes at a level higher than that which might otherwise prevail. However, there is no assurance
that the Stabilizing Manager (or persons acting on behalf of a Stabilizing Manager) will undertake stabilization action. Any stabilization action may begin on or after the date on which adequate
public disclosure of the terms of the offer of the notes is made and, if begun, may be ended at any time, but it must end no later than the earlier of 30&nbsp;days after the issue date of the notes
and 60&nbsp;days after the date of the allotment of the notes. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
issuer has filed two registration statements (including a prospectus) with the SEC for the offering to which this communication relates. Before you invest, you should read the
prospectus included in the registration statements and other documents the issuer has filed with the SEC for more complete information about the issuer and this offering. You may get these documents
for free by visiting EDGAR on the SEC Web site at www.sec.gov. Alternatively, the issuer, any underwriter or any dealer participating in the offering will arrange to send you the prospectus if you
request it by calling toll-free 1-866-803-9204. </FONT></P>
