         On June 16,  2003,  we  announced  a proposed  public  offering of $150
million in aggregate  principal amount of Senior Subordinated Notes due 2016. We
intend to use the net  proceeds  from the offering to redeem all or a portion of
the outstanding  8-1/8% Senior Notes due 2008 of our  subsidiary,  Iron Mountain
Canada Corporation, which we have guaranteed on a senior subordinated basis, and
for general  corporate  purposes,  including  the  possible  repayment  of other
indebtedness and possible future  acquisitions  and  investments.  A copy of our
press release regarding this event is being filed as an exhibit to this report.

         In connection with the proposed  offering,  we are also disclosing that
Iron Mountain  Europe Limited,  our majority owned  subsidiary that operates our
records and information  management  business in Europe,  is  participating in a
process  for the sale of, and has made a proposal to  acquire,  the  Information
Management Services unit of Hays Plc ("Hays IMS"). We believe that Iron Mountain
Europe is one of several bidders for Hays IMS, whose  operations are principally
in the United  Kingdom and  continental  Europe.  Hays IMS' revenues in the year
ended 30 June 2002 were approximately 88.3 million pounds sterling. There can be
no assurances that we will be the successful bidder for Hays IMS.

         If we are  successful,  Iron  Mountain  Incorporated  may  provide  the
financing  to Iron  Mountain  Europe to enable it to acquire Hays IMS. We intend
for Iron Mountain Europe to seek permanent  financing to fund the acquisition or
to repay all or a portion of any such financing from Iron Mountain Incorporated.
Iron Mountain Europe is an unrestricted subsidiary under our existing indentures
and  we  anticipate  that  it  will  be an  unrestricted  subsidiary  under  the
indentures  for our  senior  subordinated  notes,  including  the notes  offered
hereby, for the foreseeable future.
