                              ABOUT THIS PROSPECTUS

     This  prospectus  is part of a  registration  statement  we filed  with the
Securities and Exchange  Commission,  or the SEC,  using a "shelf"  registration
process. Under this shelf process, we may sell any combination of the securities
described  in this  prospectus  in one or more  offerings  up to a total  dollar
amount of proceeds of  $500,000,000  or the  equivalent  denominated  in foreign
currency.  This  prospectus  provides  you  with a  general  description  of the
securities  we may  offer.  Each  time we sell  securities,  we will  provide  a
prospectus  supplement  containing specific  information about the terms of that
offering.  The prospectus supplement may also add, update, or change information
contained  in this  prospectus.  You should  read both this  prospectus  and any
prospectus supplement,  together with additional information described under the
heading "Where You Can Find More  Information"  and "Documents  Incorporated  By
Reference."

     We have not included,  or  incorporated  by reference,  separate  financial
statements of IM Capital Trust I in this  prospectus.  Neither we nor IM Capital
Trust I consider  these  financial  statements  material to holders of the trust
preferred securities because:

     o    IM Capital Trust is a special purpose entity;

     o    IM Capital  Trust does not have any operating  history or  independent
          operations; and

     o    IM  Capital  Trust is not  engaged  in,  nor will it  engage  in,  any
          activity   other  than  issuing  trust   preferred  and  trust  common
          securities,  investing in and holding our debt securities and engaging
          in related activities.

     Furthermore,  the combination of our obligations under our debt securities,
the  associated  indentures,  IM Capital  Trust's  declaration  of trust and our
related  guarantees  provide a full and  unconditional  guarantee of payments of
distributions  and other  amounts  due on the  trust  preferred  securities.  In
addition,  we do not expect that IM Capital Trust will file reports with the SEC
under the Securities Exchange Act of 1934, as amended.

                                      (i)


     You  should  rely only on the  information  incorporated  by  reference  or
provided  in this  document  and any  prospectus  supplement.  Neither we nor IM
Capital  Trust  have  authorized  anyone  else to  provide  you  with  different
information.  Neither  we nor IM  Capital  Trust  are  making  an offer of these
securities in any jurisdiction where it is unlawful. If anyone provides you with
different or inconsistent information, you should not rely on it. You should not
assume that the  information in this prospectus is accurate as of any date other
than the date on the front of this document.

     References  in this  prospectus  to the terms  "we," "our" or "us" or other
similar terms mean Iron Mountain Incorporated and its consolidated subsidiaries,
unless we state otherwise or the context indicates otherwise. References in this
prospectus to "IM Capital Trust" mean IM Capital Trust I.

              CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

     We have made and incorporated by reference statements in this document that
constitute  "forward-looking  statements" as that term is defined in the federal
securities  laws.  These  forward-looking  statements  concern  our  operations,
economic performance,  goals, beliefs,  strategies,  objectives,  plans, current
expectations and financial condition. The forward-looking statements are subject
to various known and unknown risks, uncertainties and other factors. When we use
words  such as  "believes,"  "expects,"  "anticipates,"  "estimates"  or similar
expressions, we are making forward-looking statements.

     Although  we  believe  that our  forward-looking  statements  are  based on
reasonable  assumptions,  our  expected  results may not be achieved  and actual
results may differ  materially  from our  expectations.  Important  factors that
could cause actual results to differ from  expectations  include,  among others,
those set forth below. For a more detailed  discussion of some of these factors,
please read carefully the information under "Risk Factors" beginning on page 2.

     o    changes in customer preferences and demand for our services;

     o    changes  in the  price  for  our  services  relative  to the  cost  of
          providing such services;

     o    the cost and availability of financing for contemplated growth;

     o    our ability or  inability  to complete  acquisitions  on  satisfactory
          terms and to integrate acquired companies efficiently;

     o    in the various digital  businesses on which we are embarking,  capital
          and technical  requirements will be beyond our means,  markets for our
          services will be less robust than anticipated,  or competition will be
          more intense than anticipated;

     o    the  possibility  that  business  partners  upon  whom we  depend  for
          technical  assistance or management and acquisition  expertise outside
          the United States will not perform as anticipated;

     o    changes in the political and economic environments in the countries in
          which our international subsidiaries operate; and

     o    other  trends in  competitive  or economic  conditions  affecting  our
          financial   condition   or  results  of   operations   not   presently

                                IM CAPITAL TRUST

     IM Capital  Trust is a  subsidiary  of ours.  IM Capital  Trust was created
under the  Delaware  Statutory  Trust Act and is  governed by a  declaration  of
trust,  as it may be amended and restated from time to time,  among the trustees
of IM Capital Trust and us.

     When IM Capital Trust issues its trust preferred securities, the holders of
the trust preferred  securities will own all of the issued and outstanding trust
preferred  securities of IM Capital Trust. We will acquire all of the issued and
outstanding  trust  common  securities  of IM  Capital  Trust,  representing  an
undivided beneficial interest in the assets of IM Capital Trust of at least 3%.

     IM Capital Trust will exist primarily for the purposes of:

     o    issuing its trust preferred and trust common securities;

     o    investing the proceeds from the sale of its trust  preferred and trust
          common securities in our debt securities; and

     o    engaging in other  activities  only as are  necessary or incidental to
          issuing its securities and purchasing and holding our debt securities.

     The debt  securities IM Capital Trust purchases from us may be subordinated
debt securities or senior debt securities,  and may be fully and unconditionally
guaranteed by substantially  all of our present and future wholly owned domestic
subsidiaries.  We  will  specify  the  type  of debt  security  in a  prospectus
supplement.

                                      -1-


     IM Capital Trust has three  trustees.  One of the trustees,  referred to as
the regular  trustee,  is an  individual  who is an officer and employee of Iron
Mountain. Additional regular trustees may be appointed in the future. The second
trustee is The Bank of New York,  which serves as the property trustee under the
declaration  of trust  for  purposes  of the  Trust  Indenture  Act of 1939,  as
amended.  The third  trustee is The Bank of New York  (Delaware),  which has its
principal place of business in the State of Delaware, and serves as the Delaware
trustee of IM Capital Trust.

     The Bank of New York,  acting in its  capacity as guarantee  trustee,  will
hold for the  benefit  of the  holders  of trust  preferred  securities  a trust
preferred  securities  guarantee,  which will be separately  qualified under the
Trust Indenture Act of 1939.

     Unless otherwise provided in the applicable prospectus supplement,  because
we will own all of the trust common securities of IM Capital Trust, we will have
the exclusive  right to appoint,  remove or replace  trustees and to increase or
decrease  the number of  trustees.  In most cases,  there will be at least three
trustees.  The term of IM Capital  Trust  will be  described  in the  applicable
prospectus  supplement,  but it may dissolve earlier,  as provided in IM Capital
Trust's  declaration  of trust,  as it may be amended and restated  from time to
time.

     The rights of the holders of the trust  preferred  securities of IM Capital
Trust,  including  economic rights,  rights to information and voting rights and
the  duties  and  obligations  of the  trustees  of IM  Capital  Trust,  will be
contained in and governed by the declaration of trust of IM Capital Trust, as it
may be amended and restated from time to time, the Delaware  Statutory Trust Act
and the Trust Indenture Act of 1939.

                                  RISK FACTORS

     You should consider  carefully the following  factors and other information
in this prospectus before deciding to invest in our securities.

Acquisition and International Expansion Risks

Failure to successfully  integrate  acquired  operations could reduce our future
results of operations.

     The success of any acquisition  depends in part on our ability to integrate
the acquired company. The process of integrating acquired businesses may involve
unforeseen  difficulties  and  may  require  a  disproportionate  amount  of our
management's attention and our financial and other resources.

     We can give no assurance  that we will  ultimately  be able to  effectively
integrate and manage the operations of any acquired business.  Nor can we assure
you  that we  will be able to  maintain  or  improve  the  historical  financial
performance of Iron Mountain or our  acquisitions.  The failure to  successfully
integrate  these  cultures,   operating  systems,   procedures  and  information
technologies could have a material adverse effect on our results of operations.

     Failure to achieve expected cost savings and unanticipated costs related to
integrating acquired companies could adversely affect our results of operations.

     Our estimates of annual operating cost savings for acquired companies are a
function of the nature and timing of individual  acquisition  integration plans.
These savings  result  primarily  from the  elimination  of redundant  corporate
expenses and more efficient operations and utilization of real estate.  However,
unanticipated  future operating  expenses or acquisition  related  expenses,  or
other  adverse  developments,  could reduce or delay  realization  of these cost
savings and materially affect our results of operations.

     As a result,  our operating  results may fluctuate  from quarter to quarter
due to the  integration of current and future  acquisitions.  It is difficult to
precisely  forecast the magnitude and timing of integration  costs.  These costs
may  be  material  to the  financial  results  of a  given  quarter.  Therefore,
operating  results for any fiscal  quarter may not be  indicative of the results
that may be achieved for any subsequent quarter or for a full fiscal year.

                                      -2-


We may be unable to continue our international expansion.

     Our  growth  strategy  involves  expanding  operations  into  international
markets, and we expect to continue this expansion. Europe and Latin America have
been our primary  areas of focus for  international  expansion.  We have entered
into joint ventures and have acquired all or a majority of the equity in records
and information  management services businesses operating in these areas and are
actively pursuing additional opportunities. This growth strategy involves risks.
We may be unable to pursue this strategy in the future.  For example,  we may be
unable to:

     o    identify suitable companies to acquire;

     o    complete acquisitions on satisfactory terms;

     o    incur  additional debt necessary to acquire  suitable  companies if we
          are unable to pay the purchase  price out of working  capital,  common
          stock or other equity securities; or

     o    enter into successful business  arrangements for technical  assistance
          or management and acquisition expertise outside of the United States.

     We also  compete with other  records and  information  management  services
providers for companies to acquire.  Some of our competitors may possess greater
financial and other  resources than we do. If any such competitor were to devote
additional resources to such acquisition candidates or focus its strategy on our
international markets, our results of operations could be adversely affected.

Operational Risks

We face competition for customers.

     We compete with our current and potential  customers'  internal records and
information management services  capabilities.  We can provide no assurance that
these  organizations  will begin or continue to use an outside company,  such as
our company, for their future records and information  management services needs
or that  they  will use us to  provide  these  services.  We also  compete  with
multiple records and information management services providers in all geographic
areas where we operate.

We may not be able to effectively expand our digital businesses.

     We have implemented the early stages of our planned  expansion into various
digital businesses.  Our entrance into these markets poses certain unique risks.
For example, we may be unable to:

     o    raise the amount of capital  necessary to  effectively  participate in
          these businesses;

     o    develop, hire or otherwise obtain the necessary technical expertise;

     o    accurately  predict the size of the markets for any of these services;
          or

     o    compete  effectively  against  other  companies  who  possess  greater
          technical expertise, capital or other necessary resources.

     In addition,  the business  partners  upon whom we depend for technical and
management  expertise,  as well as the hardware and software products we need to
complement our services, may not perform as expected.

Our  customers  may shift from paper storage to  alternative  technologies  that
require less physical space.

     We derive  most of our  revenues  from the storage of paper  documents  and
related services. This storage requires significant physical space.  Alternative
storage technologies exist, many of which require  significantly less space than
paper. These technologies include computer media, microform,  CD-ROM and optical
disk. To date,

                                      -3-


none of these technologies has replaced paper as the principal means for storing
information.  However,  we can  provide no  assurance  that our  customers  will
continue to store most of their records in paper format. A significant  shift by
our customers to storage of data through non-paper based  technologies,  whether
now existing or developed in the future, could adversely affect our business.

We may be subject to certain costs and potential liabilities associated with the
real estate required for our businesses.

     Because  our  businesses  are heavily  dependent  on real  estate,  we face
special  risks  attributable  to the real estate we own or  operate.  Such risks
include:

     o    variable occupancy costs and difficulty locating suitable sites due to
          fluctuations in the real estate market;

     o    uninsured  losses  or  damage  to  our  storage  facilities  due to an
          inability to obtain full coverage on a  cost-effective  basis for some
          casualties,  such as earthquakes,  or any coverage for certain losses,
          such as losses from riots or terrorist activities;

     o    loss of our investment in, and anticipated profits and cash flow from,
          damaged property that is uninsured;

     o    liability   under  certain   environmental   laws  for  the  costs  of
          investigation  and cleanup of contaminated real estate owned or leased
          by us,  whether  or not we know  of,  or  were  responsible  for,  the
          contamination,  or the contamination occurred while we owned or leased
          the property;

     o    third  party  claims   resulting   from  the  off-site   migration  of
          contamination  initiating  on real estate  that we own or operate,  or
          exposure  to  hazardous  substances,   including   asbestos-containing
          materials, located on our property; and

     o    an inability to sell, rent,  mortgage or use contaminated  real estate
          owned or leased by us.

     Some  of our  current  and  formerly  owned  or  operated  properties  were
previously used for industrial or other purposes that involved the use, storage,
generation  and/or  disposal of hazardous  substances  and wastes and  petroleum
products.   In  some  instances  these  properties  included  the  operation  of
underground storage tanks.  Although we have from time to time conducted limited
environmental  investigations and remedial  activities at some of our former and
current facilities,  we have not undertaken an in-depth  environmental review of
all of our properties.  We therefore may be potentially liable for environmental
costs like those discussed above.

International operations may pose unique risks.

     As of March 31, 2003, we provided services in 47 markets outside the United
States. As part of our growth strategy, we expect to continue to acquire records
and information management services businesses in foreign markets. International
operations are subject to numerous risks, including:

     o    the risk that the business  partners upon whom we depend for technical
          assistance  or management  and  acquisition  expertise  outside of the
          United States will not perform as expected;

     o    the impact of foreign government regulations;

     o    the volatility of certain foreign economies in which we operate;

     o    political uncertainties;

     o    differences in business practices; and

     o    foreign currency fluctuations.

                                      -4-


     In particular, our net income can be significantly affected by fluctuations
in foreign  currencies  associated with the U.S. dollar denominated debt of some
of our  foreign  subsidiaries  and  certain  intercompany  balances  between our
domestic entities and our foreign subsidiaries.

Indebtedness and Other Risks

Our substantial indebtedness could adversely affect our financial health.

     We have substantial  indebtedness,  which could have important consequences
to you. The risks associated with our substantial indebtedness include:

     o    inability to adjust to adverse economic conditions;

     o    inability  to  fund  future  working  capital,  acquisitions,  capital
          expenditures and other general corporate requirements;

     o    limits on our  flexibility in planning for, or reacting to, changes in
          our  business  and the records  and  information  management  services
          industry;

     o    limits  on  future  borrowings  under our  existing  or future  credit
          arrangements,  which could affect our ability to pay our  indebtedness
          or to fund our other liquidity needs;

     o    inability to generate  sufficient funds to cover required  interest or
          principal amortization payments; and

     o    restrictions   on  our  ability  to  refinance  our   indebtedness  on
          commercially reasonably terms.

Our indebtedness may increase as we continue to borrow under existing and future
credit arrangements in order to finance future acquisitions and for general
corporate purposes, which would increase the associated risks.

Restrictive loan covenants may limit our ability to pursue our growth strategy.

     Our credit facility and our indentures contain covenants restricting or
limiting our ability to, among other things:

     o    incur additional indebtedness;

     o    pay dividends or make other restricted payments;

     o    make asset dispositions;

     o    create or permit liens; and

     o    make capital expenditures and other investments.

     These restrictions may adversely affect our ability to pursue our
acquisition and other growth strategies.

Certain  provisions  in  our  governing   documents  and  indentures,   and  the
composition of our shareholders,  might discourage or prevent third parties from
acquiring control of our outstanding capital stock.

     Certain  provisions  of our  articles  of  incorporation,  our  bylaws  and
existing  indentures  might  discourage or prevent a third party from  acquiring
actual or potential control of us by:

     o    making it more difficult to consummate  certain types of  transactions
          such as mergers, tender offers or proxy contests;

                                      -5-


     o    limiting  shareholders'  ability to quickly change the  composition of
          our board of directors due to our classified board of directors;

     o    allowing existing management to exercise  significant control over our
          affairs during periods where we are threatened by a change in control;

     o    allowing our board of directors to issue shares of preferred  stock in
          the  future  without  further  shareholder   approval  and  with  full
          discretion   as  to  terms,   conditions,   rights,   privileges   and
          preferences; and

     o    requiring  that we offer to  purchase  all or some of our  outstanding
          senior  subordinated  notes and other publicly issued notes in certain
          circumstances that amount to a change of control under our indentures.

     In  addition,   because  relatively  few  large   shareholders   control  a
significant percentage of our voting power, these shareholders may:

     o    prevent certain types of transactions involving an actual or potential
          change of control of us, including  transactions  made at prices above
          the prevailing market price of our common stock; and

     o    significantly  affect the  election  of our  directors  who,  in turn,
          control our management and affairs.

                       RATIO OF EARNINGS TO FIXED CHARGES

     The following table sets forth our consolidated ratio of earnings to fixed
charges for the periods indicated (dollars in thousands):

- -------------------------------
(1) We reported a loss from continuing  operations  before  provision for income
taxes and minority  interest for the years ended  December 31, 2000 and December
31, 2001 and we would have needed to generate  additional income from operations
before provision for income taxes and minority interest of $18,032 and $8,131 to
cover our fixed charges of $154,975 and $177,032, respectively.

     The ratios of earnings to fixed  charges  presented  above were computed by
dividing our earnings by fixed  charges.  For this  purpose,  earnings have been
calculated by adding fixed charges to income (loss) from  continuing  operations
before provision for income taxes and minority  interest.  Fixed charges consist
of interest costs,  whether expensed or capitalized,  the interest  component of
rental expense,  if any,  amortization of debt discounts and deferred  financing
costs, whether expensed or capitalized.

                                 USE OF PROCEEDS

     Unless otherwise described in a prospectus supplement, we intend to use the
net  proceeds  from the sale of the offered  securities  for  general  corporate
purposes,  which may include  acquisitions,  investments  and the  repayment  of
indebtedness  outstanding at a particular time.  Pending this  utilization,  the
proceeds from the sale of the offered securities will be invested in short-term,
dividend-paying or interest-bearing investment grade securities.

     IM  Capital  Trust  will use all net  proceeds  from the sale of its  trust
preferred  securities  and its trust  common  securities  to  purchase  our debt
securities.

                       DESCRIPTION OF OUR DEBT SECURITIES

     The debt  securities  will be  direct  obligations  of ours,  which  may be
secured or unsecured, and which may be senior or subordinated indebtedness.  The
debt  securities  may be fully and  unconditionally  guaranteed  on a secured or
unsecured,  senior or subordinated basis, jointly and severally by substantially
all of our direct and indirect  wholly  owned  domestic  subsidiaries.  The debt
securities will be issued under one or more indentures between us and a trustee.
Any  indenture  will be subject to, and governed by, the Trust  Indenture Act of
1939. The statements made in this prospectus  relating to any indentures and the
debt  securities  to be issued  under the  indentures  are  summaries of certain
anticipated provisions of the indentures and are not complete.

     We have  filed  copies  of the  forms  of  indentures  as  exhibits  to the
registration  statement of which this prospectus is part and will file any final
indentures and supplemental  indentures if we issue debt securities.  You should
refer to those  indentures  for the complete terms of the debt  securities.  See
"Where You Can Find More  Information."  In  addition,  you should  consult  the
applicable prospectus supplement for particular terms of our debt securities.

General

     We may issue debt securities that rank "senior,"  "senior  subordinated" or
"subordinated." The debt securities that we refer to as "senior securities" will
be direct  obligations  of ours and will rank  equally  and  ratably in right of
payment with other  indebtedness of ours that is not subordinated.  We may issue
debt  securities  that will be  subordinated  in right of  payment  to the prior
payment in full of senior indebtedness,  as defined in the applicable prospectus
supplement,  and may  rank  equally  and  ratably  with our  outstanding  senior
subordinated  indebtedness and any other senior  subordinated  indebtedness.  We
refer to these as  "senior  subordinated  securities."  We may also  issue  debt
securities  that  may  be  subordinated  in  right  of  payment  to  the  senior
subordinated securities. These would be "subordinated securities." We have filed
with the registration  statement of which this prospectus is part three separate
forms of indenture, one each for the senior securities,  the senior subordinated
securities and the subordinated securities.

     We may issue the debt  securities  without limit as to aggregate  principal
amount,  in one or more  series,  in each  case as we  establish  in one or more
supplemental indentures.  We need not issue all debt securities of one series at
the same time. Unless we otherwise provide, we may reopen a series,  without the
consent of the holders of such series, for issuances of additional securities of
that series.

     We anticipate  that any  indenture  will provide that we may, but need not,
designate more than one trustee under an indenture,  each with respect to one or
more series of debt securities. Any trustee under any indenture may resign or be
removed with respect to one or more series of debt securities and we may appoint
a successor trustee to act with respect to that series.

     The  applicable  prospectus  supplement  will  describe the specific  terms
relating  to the  series of debt  securities  we will  offer,  including,  where
applicable, the following:

     o    the  title  and  series   designation  and  whether  they  are  senior
          securities, senior subordinated securities or subordinated securities;

     o    the aggregate principal amount of the securities;

                                      -8-


     o    the percentage of the principal amount at which we will issue the debt
          securities  and,  if  other  than  the  principal  amount  of the debt
          securities, the portion of the principal amount of the debt securities
          payable upon maturity of the debt securities;

     o    if convertible,  the initial  conversion  price, the conversion period
          and any other terms governing such conversion;

     o    the stated maturity date;

     o    any fixed or variable interest rate or rates per annum;

     o    the place where  principal,  premium,  if any,  and  interest  will be
          payable and where the debt securities can be surrendered for transfer,
          exchange or conversion;

     o    the date from  which  interest  may accrue  and any  interest  payment
          dates;

     o    any sinking fund requirements;

     o    any provisions for redemption,  including the redemption price and any
          remarketing arrangements;

     o    whether the securities are denominated or payable in U.S. dollars or a
          foreign currency or units of two or more foreign currencies;

     o    the events of default and covenants of such securities,  to the extent
          different from or in addition to those described in this prospectus;

     o    whether  we  will  issue  the  debt   securities  in  certificated  or
          book-entry form;

     o    whether the debt  securities will be in registered or bearer form and,
          if in  registered  form,  the  denominations  if  other  than  in even
          multiples  of $1,000 and, if in bearer  form,  the  denominations  and
          terms and conditions relating thereto;

     o    whether we will issue any of the debt  securities in permanent  global
          form  and,  if so,  the  terms  and  conditions,  if any,  upon  which
          interests  in the global  security  may be  exchanged,  in whole or in
          part, for the  individual  debt  securities  represented by the global
          security;

     o    the applicability,  if any, of the defeasance and covenant  defeasance
          provisions described in this prospectus or any prospectus supplement;

     o    whether we will pay additional amounts on the securities in respect of
          any tax, assessment or governmental charge and, if so, whether we will
          have the option to redeem the debt  securities  instead of making this
          payment;

     o    the subordination provisions, if any, relating to the debt securities;

     o    if the debt  securities  are to be issued  upon the  exercise  of debt
          warrants,  the time, manner and place for them to be authenticated and
          delivered;

     o    whether  any of our  subsidiaries  will be bound  by the  terms of the
          indenture, in particular any restrictive covenants;

     o    the  provisions  relating  to  any  security  provided  for  the  debt
          securities; and

     o    the provisions relating to any guarantee of the debt securities.

                                      -9-


     We may issue debt securities at less than the principal amount payable upon
maturity.  We refer to these securities as "original issue discount securities."
We may also issue debt  securities  over par from time to time.  If  material or
applicable,  we will describe in the applicable  prospectus  supplement  special
U.S.  federal  income tax,  accounting  and other  considerations  applicable to
original issue discount securities or debt securities issued over par.

     Except as may be set forth in any prospectus supplement,  an indenture will
not  contain  any  other  provisions  that  would  limit  our  ability  to incur
indebtedness or that would afford holders of the debt  securities  protection in
the event of a highly  leveraged or similar  transaction  involving us or in the
event of a change  of  control.  You  should  review  carefully  the  applicable
prospectus  supplement  for  information  with  respect to events of default and
covenants applicable to the securities being offered.

Denominations, Interest, Registration and Transfer

     Unless otherwise described in the applicable prospectus supplement, we will
issue the debt  securities  of any  series  that are  registered  securities  in
denominations  that are even multiples of $1,000,  other than global securities,
which may be of any denomination.

     Unless otherwise specified in the applicable prospectus supplement, we will
pay the interest, principal and any premium at the corporate trust office of the
trustee. At our option, however, we may make payment of interest by check mailed
to the  address  of the  person  entitled  to the  payment  as it appears in the
applicable  register  or by wire  transfer of funds to that person at an account
maintained within the United States.

     If we do not  punctually  pay or duly  provide for interest on any interest
payment date, the defaulted interest will be paid either:

     o    to the person in whose name the debt  security  is  registered  at the
          close of business on a special record date we will fix; or

     o    in any other lawful manner as the applicable indenture describes.

     You may have your debt  securities  divided  into more debt  securities  of
smaller   denominations  or  combined  into  fewer  debt  securities  of  larger
denominations,  as long as the total  principal  amount is not changed.  We call
this an "exchange."

     You  may  exchange  or  transfer  debt  securities  at  the  office  of the
applicable  trustee.  The  trustee  acts  as  our  agent  for  registering  debt
securities  in the names of holders and  transferring  debt  securities.  We may
change this  appointment to another  entity or perform it ourselves.  The entity
performing the role of maintaining the list of registered  holders is called the
"registrar." It will also perform transfers.

     You will not be  required  to pay a service  charge to transfer or exchange
debt  securities,  but  you  may  be  required  to pay  for  any  tax  or  other
governmental charge associated with the exchange or transfer. The registrar will
make the  transfer  or  exchange  only if it is  satisfied  with  your  proof of
ownership.

Merger, Consolidation or Sale of Assets

     Under any  indenture,  we are generally  permitted to  consolidate or merge
with another  company.  We are also permitted to sell  substantially  all of our
assets to another company.  However, we may not take any of these actions unless
all of the following conditions are met:

o        If we merge out of existence or sell our assets, the other company must
         be a corporation, partnership or other entity organized under the laws
         of a State or the District of Columbia or under federal law. The other
         company must agree to be legally responsible for the debt securities.

                                      -10-


o        Immediately after the consolidation or merger or sale of assets we are
         not in default on the debt securities. A default for this purpose would
         include any event that would be an event of default without regard to
         notice obligations or the length of time of the default.

Certain Covenants

     Provision of Financial  Information.  We will deliver to the trustee a copy
of our annual report to  shareholders,  our reports on Forms 10-K,  10-Q and 8-K
and any other  reports  that we are  required  to file with the SEC  pursuant to
Section 13 or 15(d) of the Securities Exchange Act of 1934.

     Additional   Covenants.   Any   additional  or  different   covenants,   or
modifications to these covenants,  with respect to any series of debt securities
will be set forth in the applicable prospectus supplement.

Events of Default and Related Matters

     Events of Default. The term "event of default" means any of the following:

     o    we do not pay the  principal or any premium on a debt  security on its
          due date;

     o    we do not pay  interest on a debt  security  within 30 days of its due
          date;

     o    we do not deposit any sinking fund payment on its due date;

     o    we fail to comply with any "change of  control"  covenant  included in
          the applicable indenture;

     o    we remain in breach of any other term of the applicable  indenture for
          60 days after we receive a notice of default stating we are in breach.
          Either the trustee or the holders of 25% in  principal  amount of debt
          securities of the affected series may send the notice;

     o    we default  in the  payment  of any of our other  indebtedness  over a
          specified  amount that results in the  acceleration of the maturity of
          the  indebtedness  or  constitutes  a default  in the  payment  of the
          indebtedness  at final maturity,  but only if the  indebtedness is not
          discharged or the  acceleration is not rescinded or annulled;

     o    we or one of our  "significant  subsidiaries"  files for bankruptcy or
          certain  other  events in  bankruptcy,  insolvency  or  reorganization
          occur; and

     o    any other event of default,  or  modification  of any of the foregoing
          events of default,  described in the applicable  prospectus supplement
          occurs.

The term "significant subsidiary" means each of our significant subsidiaries (as
defined in Regulation S-X promulgated under the Securities Act of 1933).

     Remedies If an Event of Default Occurs. If an event of default has occurred
and has not been cured,  the trustee or the holders of at least 25% in principal
amount of the debt  securities  of the  affected  series may  declare the entire
principal  amount  of all  the  debt  securities  of that  series  to be due and
immediately  payable.  We call this a "declaration of acceleration of maturity."
If an  event  of  default  occurs  because  of  certain  events  in  bankruptcy,
insolvency or reorganization, the principal amount of all the debt securities of
that series will be automatically accelerated, without any action by the trustee
or any holder. At any time after the trustee or the holders have accelerated any
series of debt  securities,  the  holders  of at least a majority  in  principal
amount  of the  debt  securities  of the  affected  series  may,  under  certain
circumstances, rescind and annul such acceleration.

     The  trustee  will  be  required  to give  notice  to the  holders  of debt
securities  within 90 days of a default of which the trustee has knowledge under
the  applicable  indenture  unless the  default  has been  cured or waived.  The
trustee may withhold  notice to the holders of any series of debt  securities of
any default with respect to that series,  except a

                                      -11-


default in the payment of the  principal of or interest on any debt  security of
that  series,  if  specified  responsible  officers of the trustee in good faith
determine that withholding the notice is in the interest of the holders.

     Except in cases of default,  where the trustee has some special duties, the
trustee is not required to take any action under the applicable indenture at the
request  of  any  holders  unless  the  holders  offer  the  trustee  reasonable
protection  from expenses and liability.  We refer to this as an "indemnity." If
reasonable indemnity is provided,  the holders of a majority in principal amount
of the outstanding securities of the relevant series may direct the time, method
and place of  conducting  any lawsuit or other formal  legal action  seeking any
remedy  available to the  trustee.  These  majority  holders may also direct the
trustee in performing any other action under the applicable  indenture,  subject
to certain limitations.

     Before you bypass the trustee  and bring your own  lawsuit or other  formal
legal  action  or take  other  steps to  enforce  your  rights or  protect  your
interests relating to the debt securities, the following must occur:

     o    you must give the trustee  written notice that an event of default has
          occurred and remains uncured;

     o    the  holders of at least 25% in  principal  amount of all  outstanding
          securities of the relevant series must make a written request that the
          trustee take action because of the default,  and must offer  indemnity
          satisfactory  to the  trustee  against the costs,  expenses  and other
          liabilities of taking that action;

     o    the trustee  must have not taken  action for 60 days after  receipt of
          the above notice, request and offer of indemnity; and

     o    the  trustee  does not  receive  direction  contrary  to the  holders'
          written  request,  within 60 days  following  receipt of the  holders'
          written request, from holders of a majority in principal amount of the
          outstanding securities of that series.

However,  you are  entitled  at any time to bring a lawsuit  for the  payment of
money due on your security after its due date.

     Every year we will furnish to the trustee a written statement by certain of
our officers  certifying  that to their  knowledge we are in compliance with the
applicable indenture and the debt securities, or else specifying any default.

Modification of an Indenture

     There are three types of changes we can make to the indentures and the debt
securities:

     Changes Requiring Your Approval. First, there are changes we cannot make to
your debt securities without your specific approval.  The following is a list of
those types of changes:

     o    reduce the  principal  amount of debt  securities  whose  holders must
          consent to an amendment, supplement or waiver;

     o    reduce the  principal of or change the fixed  maturity of any security
          or change any of the redemption provisions in a manner adverse to you;

     o    reduce the rate of or change the time for  payment of  interest on any
          debt security;

     o    waive a default in the payment of principal of or premium,  if any, or
          interest on any debt security  (except a rescission of acceleration of
          such  debt  securities  by the  holders  of at  least  a  majority  in
          aggregate principal amount of the then outstanding debt securities and
          a waiver of the payment default that resulted from such acceleration);

     o    make any debt security payable in money other than that stated in such
          debt security;

                                      -12-


     o    make any change in the provisions of the indenture relating to waivers
          of past defaults or your right to receive  payments of principal of or
          premium, if any, or interest on the debt securities;

     o    except  under  certain  circumstances   described  in  the  applicable
          prospectus supplement,  waive a redemption payment with respect to any
          debt security;

     o    if the debt securities are guaranteed,  other than as described in the
          applicable  prospectus  supplement,  release  any  guarantor  from its
          obligations under its subsidiary  guarantee,  or change any subsidiary
          guarantee in any manner that would materially adversely affect you; or

     o    make any change in the foregoing amendment and waiver provisions.

     Changes  Requiring  a  Majority  Vote.  The  second  type of  change  to an
indenture  and the debt  securities is the kind that requires a vote in favor by
holders of a majority of the principal  amount of the particular  series of debt
securities affected. Most changes fall into this category, except for clarifying
changes and certain other  changes that would not  materially  adversely  affect
holders of the debt securities. We require the same vote to obtain a waiver of a
past default.  However,  we cannot  obtain a waiver of a payment  default or any
other  aspect of an  indenture or the debt  securities  listed under  "--Changes
Requiring Your Approval" unless we obtain your individual consent to the waiver.

     Changes Not Requiring  Approval.  The third type of change does not require
any vote by holders of debt securities.  This type is limited to  clarifications
and certain other changes that would not materially  adversely affect holders of
the debt securities.

     Further  Details  Concerning  Voting.  Debt  securities  are not considered
outstanding,  and therefore  not eligible to vote,  if we have  deposited or set
aside in trust for you money for their  payment or redemption or if we or one of
our affiliates own them.  Debt  securities are also not eligible to vote if they
have been fully defeased as described  immediately below under "--Defeasance and
Covenant  Defeasance--Full  Defeasance." For original issue discount securities,
we will use the  principal  amount  that would be due and  payable on the voting
date if the  maturity  of the debt  securities  were  accelerated  to that  date
because of a default.

Defeasance and Covenant Defeasance

     Full  Defeasance.  We can, under  particular  circumstances,  effect a full
defeasance  of your  series of debt  securities.  By this we mean we can legally
release  ourselves from any payment or other  obligations on the debt securities
if we deliver certain  certificates and opinions to the trustee and put in place
the following arrangements to repay you:

     o    We must deposit in trust for your benefit and the benefit of all other
          direct holders of the debt  securities a combination of money and U.S.
          government or U.S. government agency notes or bonds that will generate
          enough cash to make interest,  principal and any other payments on the
          debt securities on their various due dates. If the debt securities are
          denominated  in a  foreign  currency,  then  we  may  deposit  foreign
          government notes or bonds.

     o    The current  federal  tax law must be changed or an  Internal  Revenue
          Service  ruling must be issued  permitting  the above deposit  without
          causing you to be taxed on the debt securities any differently than if
          we did not  make  the  deposit  and just  repaid  the debt  securities
          ourselves.  Under  current  federal tax law, the deposit and our legal
          release  from the debt  securities  would be treated as though we took
          back  your  debt  securities  and gave you your  share of the cash and
          notes or bonds deposited in trust. In that event,  you could recognize
          gain or loss on the debt securities you give back to us.

     o    We must deliver to the trustee a legal opinion  confirming the tax law
          change described above.

     o    No default  shall be in effect on the date of deposit  or,  insofar as
          bankruptcy and insolvency  defaults are concerned,  at any time in the
          period  ending on the 91st day after the date of deposit  (or  greater
          period of

                                      -13-


          time in which any such  deposit of trust  funds may remain  subject to
          bankruptcy law insofar as those apply to the deposit by us).

     o    The full  defeasance  must not result in a breach or violation  of, or
          constitute  a default  under,  any material  agreement  or  instrument
          (other than the  applicable  indenture)  to which we are a party or by
          which we are bound.

     o    We must  deliver  to the  trustee  an opinion of counsel to the effect
          that after the 91st day  following  the deposit,  the trust funds will
          not be subject to the effect of any applicable bankruptcy, insolvency,
          reorganization  or similar laws affecting  creditors' rights generally
          and various other opinions of counsel and officers' certificates.

     If we did  accomplish a full  defeasance,  you would have to rely solely on
the trust deposit for repayment on the debt securities. You could not look to us
for repayment in the unlikely event of any  shortfall.  The trust deposit would,
however, most likely be protected from claims of our lenders and other creditors
if we ever became  bankrupt or  insolvent.  You would also be released  from any
subordination provisions.

     Notwithstanding  the foregoing,  the following rights and obligations shall
survive full defeasance:

     o    your rights to receive payments from the trust when payments are due;

     o    our obligations  relating to  registration  and transfer of securities
          and lost or mutilated certificates;

     o    our  obligations  to maintain a payment  office and to hold moneys for
          payment in trust;

     o    the rights,  powers, trusts, duties and immunities of the trustee, and
          our obligations in connection therewith; and

     o    the provisions of the indenture relating to defeasance.

     Covenant  Defeasance.  Under current  federal tax law, we can make the same
type of deposit  described  above and be released  from some of the  restrictive
covenants in the debt securities.  This is called "covenant defeasance." In that
event,  you would lose the protection of those  restrictive  covenants but would
gain the  protection of having money and  securities set aside in trust to repay
the debt securities and you would be released from any subordination provisions.
In order to achieve covenant  defeasance,  we must do certain things,  including
the following:

     o    we must deposit in trust for your benefit and the benefit of all other
          direct holders of the debt  securities a combination of money and U.S.
          government or U.S.  government  agency notes or bonds (or, in the case
          of  debt  securities  denominated  in  a  foreign  currency,   foreign
          government  notes or bonds)  that will  generate  enough  cash to make
          interest,  principal and any other payments on the debt  securities on
          their various due dates;

     o    we must deliver to the trustee a legal opinion  confirming  that under
          current  federal tax law we may make the above deposit without causing
          you to be taxed on the debt securities any differently  than if we did
          not make the deposit and just repaid the debt securities ourselves;

     o    no default  shall be in effect on the date of deposit  or,  insofar as
          bankruptcy and insolvency  defaults are concerned,  at any time in the
          period  ending on the 91st day after the date of deposit  (or  greater
          period of time in which any such  deposit  of trust  funds may  remain
          subject to  bankruptcy  law  insofar as those  apply to the deposit by
          us);

     o    the covenant  defeasance  must not result in a breach or violation of,
          or constitute a default  under,  any material  agreement or instrument
          (other than the  applicable  indenture)  to which we are a party or by
          which we are bound; and

                                      -14-


     o    we must  deliver  to the  trustee  an opinion of counsel to the effect
          that after the 91st day  following  the deposit,  the trust funds will
          not be subject to the effect of any applicable bankruptcy, insolvency,
          reorganization  or similar laws affecting  creditors' rights generally
          and various other opinions of counsel and officers' certificates.

     If we  accomplish  covenant  defeasance,  we will be released  from certain
covenants that we will describe in the applicable prospectus  supplement.  If we
accomplish  covenant  defeasance,  you can still look to us for repayment of the
debt  securities  if a shortfall in the trust  deposit  occurred.  If one of the
remaining events of default occurs,  for example,  our bankruptcy,  and the debt
securities  become  immediately  due  and  payable,  there  may be a  shortfall.
Depending  on the  event  causing  the  default,  you may not be able to  obtain
payment of the shortfall.

Subordination

     We will set forth in the  applicable  prospectus  supplement  the terms and
conditions,  if any, upon which any series of senior subordinated  securities or
subordinated  securities is subordinated to debt securities of another series or
to other indebtedness of ours. The terms will include a description of:

     o    the indebtedness ranking senior to the debt securities being offered;

     o    the  restrictions,  if any,  on  payments  to the  holders of the debt
          securities  being  offered  while a default with respect to the senior
          indebtedness is continuing;

     o    the  restrictions,  if any,  on  payments  to the  holders of the debt
          securities being offered following an event of default; and

     o    provisions  requiring  holders of the debt securities being offered to
          remit some payments to holders of senior indebtedness.

Conversion Rights

     The terms and  conditions,  if any,  upon  which  the debt  securities  are
convertible  into shares of our common or  preferred  stock will be set forth in
the prospectus  supplement relating thereto. Such terms will include whether the
debt  securities are convertible  into shares of our common or preferred  stock,
the conversion price (or manner of calculation thereof),  the conversion period,
provisions as to whether  conversion  will be at the option of the holders,  the
events requiring an adjustment of the conversion price and provisions  affecting
conversion  in the  event of the  redemption  of such  debt  securities  and any
restrictions on conversion.

Global Securities

     If so set forth in the applicable prospectus  supplement,  we may issue the
debt  securities  of a series,  in whole or in part,  in the form of one or more
global  securities  that will be deposited  with a depositary  identified in the
prospectus  supplement.  We may issue global  securities in either registered or
bearer form and in either temporary or permanent form. The specific terms of the
depositary  arrangement  with respect to any series of debt  securities  will be
described in the prospectus supplement.

                        DESCRIPTION OF OUR CAPITAL STOCK

     The  description  below  summarizes the more important terms of our capital
stock.  We  have  previously  filed  with  the SEC  copies  of our  articles  of
incorporation and bylaws, as amended. See "Where You Can Find More Information."
You should refer to those documents for the complete terms of our capital stock.
This summary is subject to and qualified by reference to the  description of the
particular  terms of your  securities  described  in the  applicable  prospectus
supplement.

                                      -15-


General

     Our  authorized  capital  stock  consists of  150,000,000  shares of common
stock, par value $.01 per share,  and 10,000,000  shares of preferred stock, par
value $.01 per share.

Preferred Stock

     We are  authorized  to issue up to  10,000,000  shares of preferred  stock,
$0.01 par value per share.

     This section  describes the general  terms and  provisions of our preferred
stock that we may offer from time to time. The applicable  prospectus supplement
will  describe  the  specific  terms of the shares of  preferred  stock  offered
through that  prospectus  supplement.  We will file a copy of the statement with
respect to shares that contains the terms of each new series of preferred  stock
with the SEC each  time we issue a new  series  of  preferred  stock,  and these
statements  with respect to shares will be  incorporated  by reference  into the
registration  statement of which this  prospectus is a part. Each statement with
respect to shares will  establish the number of shares  included in a designated
series and fix the designation,  powers,  privileges,  preferences and rights of
the shares of each series as well as any applicable qualifications,  limitations
or restrictions.  A holder of our preferred stock should refer to the applicable
statement  with  respect  to  shares,  our  articles  of  incorporation  and the
applicable prospectus supplement for more specific information.

     Our board of directors has been authorized, subject to limitations provided
in our articles of  incorporation,  to provide for the issuance of shares of our
preferred  stock in  multiple  series.  No  shares  of our  preferred  stock are
currently outstanding.

     With respect to each series of our preferred  stock, our board of directors
has the authority to fix the following terms:

     o    the designation of the series;

     o    the number of shares within the series;

     o    whether  dividends are cumulative  and, if cumulative,  the dates from
          which dividends are cumulative;

     o    the rate of any  dividends,  any conditions  upon which  dividends are
          payable, and the dates of payment of dividends;

     o    whether the shares are redeemable,  the redemption price and the terms
          of redemption;

     o    the  amount  payable  to a  holder  for  each  share  owned  if we are
          dissolved or liquidated;

     o    whether the shares are convertible or exchangeable,  the price or rate
          of exchange, and the applicable terms and conditions;

     o    any restrictions on issuance of shares in the same series or any other
          series; and

     o    your voting rights for the shares you own.

     Holders of our preferred stock will not have preemptive rights with respect
to shares of our preferred stock. In addition, rights with respect to shares of
our preferred stock will be subordinate to the rights of our general creditors.
If we receive the appropriate payment, shares of our preferred stock that we
issue will be fully paid and nonassessable.

     As described under "Description of Our Depositary Shares," we may, at our
option, elect to offer depositary shares evidenced by depositary receipts. If we
elect to do this, each depositary receipt will represent a fractional

                                      -16-


interest in a share of the particular  series of the preferred  stock issued and
deposited with a depositary.  The applicable  prospectus supplement will specify
that fractional interest.

     We currently plan to retain EquiServe Trust Company, N.A. as the registrar
and transfer agent of any series of our preferred stock.

Common Stock

     Voting  Rights.  Holders of common stock are entitled to one vote per share
on each  matter to be  decided  by our  shareholders,  subject  to the rights of
holders of any series of preferred  stock that may be  outstanding  from time to
time. Pursuant to our articles of incorporation,  there are no cumulative voting
rights in the election of directors.  Accordingly,  the holders of a majority of
common stock  entitled to vote in any election of directors may elect all of the
directors standing for election.

     Dividend Rights and  Limitations.  Holders of common stock will be entitled
to receive  ratably any dividends or  distributions  that our board of directors
may declare from time to time out of funds legally available for this purpose.

     Dividends and other  distributions  on common stock are also subject to the
rights of holders of any series of preferred stock that may be outstanding  from
time to time and to the restrictions in our credit agreement and indentures. See
"--Preferred Stock."

     Liquidation Rights. In the event of liquidation,  dissolution or winding up
of our affairs,  after  payment or provision for payment of all of our debts and
obligations and any preferential distributions to holders of shares of preferred
stock, if any, the holders of the common stock will be entitled to share ratably
in our remaining assets available for distribution.

     Miscellaneous.  All outstanding  shares of common stock are validly issued,
fully  paid and  nonassessable.  Our board of  directors  has the power to issue
shares of  authorized  but unissued  common stock  without  further  shareholder
action.  The issuance of these unissued shares could have the effect of diluting
the earnings per share and book value per share of currently  outstanding shares
of common stock.  The holders of common stock have no preemptive,  subscription,
redemption or conversion rights.

     Reference is made to the applicable  prospectus  supplement relating to the
common  stock  offered  by  that  prospectus   supplement  for  specific  terms,
including:

     o    amount and number of shares offered;

     o    the initial offering price, if any, and market price; and

     o    information with respect to dividends.

     Transfer  Agent and  Registrar.  The transfer  agent and  registrar for our
common  stock is EquiServe  Trust  Company,  N.A.,  150 Royall  Street,  Canton,
Massachusetts 02021. Its telephone number is (781) 575-2000.

                      DESCRIPTION OF OUR DEPOSITARY SHARES

General

     The description shown below, and in any applicable  prospectus  supplement,
of certain  provisions of any deposit agreement and of the depositary shares and
depositary  receipts  representing  depositary  shares  does not  purport  to be
complete  and is subject to and  qualified  in its  entirety by reference to the
forms of deposit  agreement and depositary  receipts relating to each applicable
series of preferred  stock.  The deposit  agreement and the depositary  receipts
contain the full legal text of the matters  described in this  section.  We will
file a copy of  those  documents  with  the  SEC at or  before  the  time of the
offering of the  applicable  series of  preferred  stock.  This  summary also is
subject to


                                      -17-


and qualified by reference to the  description of the  particular  terms of your
series of depositary shares described in the applicable prospectus supplement.

     We may,  at our  option,  elect to  offer  depositary  shares  representing
fractional  interests  in shares  of  preferred  stock,  rather  than  shares of
preferred  stock.  If we exercise  this option,  we will appoint a depositary to
issue depositary  receipts  representing those fractional  interests.  Preferred
stock of each series  represented by depositary shares will be deposited under a
separate  deposit  agreement  between  us and  the  depositary.  The  prospectus
supplement  relating to a series of depositary shares will disclose the name and
address  of the  depositary.  Subject  to the  terms of the  applicable  deposit
agreement,  each  holder of  depositary  shares  will be  entitled to all of the
distribution,  voting, conversion,  redemption, liquidation and other rights and
preferences of the preferred stock represented by those depositary shares.

     Depositary  receipts  issued pursuant to the applicable  deposit  agreement
will  evidence  ownership of  depositary  shares.  Upon  surrender of depositary
receipts  at the  office of the  depositary,  and upon  payment  of the  charges
provided  in and  subject  to the terms of the  deposit  agreement,  a holder of
depositary  shares will be entitled  to receive  the shares of  preferred  stock
underlying the surrendered depositary receipts.

Distributions

     A depositary will be required to distribute all cash distributions received
in respect of the applicable preferred stock to the record holders of depositary
shares in proportion  to the number of depositary  shares held by the holders on
the relevant record date,  which will be the same as the record date fixed by us
for the applicable series of preferred stock.  Fractions will be rounded down to
the nearest whole cent.

     If the distribution is other than in cash, a depositary will be required to
distribute  property  received by it to the record holders of depositary  shares
entitled  thereto,  in proportion,  as nearly as  practicable,  to the number of
depositary shares owned by those holders on the relevant record date, unless the
depositary determines that it is not feasible to make the distribution.  In that
case,  the depositary  may, with our approval,  sell the property and distribute
the net proceeds from the sale to the holders.

     Depositary  shares that represent  preferred  stock  converted or exchanged
will not be entitled to  distributions.  The deposit agreement will also contain
provisions relating to the manner in which any subscription or similar rights we
offer to holders of the  preferred  stock will be made  available  to holders of
depositary  shares.  All distributions will be subject to obligations of holders
to file proofs,  certificates  and other  information and to pay certain charges
and expenses to the depositary.

Withdrawal of Preferred Stock

     Holders of depositary  shares may receive the number of whole shares of the
applicable series of preferred stock and any money or other property represented
by those depositary  shares after  surrendering  the depositary  receipts at the
corporate trust office of the depositary and paying the charges  provided in the
depositary  agreement.  Partial shares of preferred stock will not be issued. If
the depositary receipts that a holder surrenders evidence a number of depositary
shares in excess of the number of depositary  shares  representing the number of
whole  shares  of  preferred  stock the  holder  wishes  to  withdraw,  then the
depositary will deliver to the holder at the same time a new depositary  receipt
evidencing the excess number of depositary  shares.  Once a holder has withdrawn
the  holder's  preferred  stock,  the holder will not be entitled to  re-deposit
those shares of preferred stock under the deposit  agreement in order to receive
depositary shares. We do not expect that there will be any public trading market
for withdrawn shares of preferred stock.

Redemption of Depositary Shares

     If we redeem a series of the  preferred  stock  underlying  the  depositary
shares,  the depositary will redeem those  depositary  shares  representing  the
preferred stock so redeemed from the proceeds  received by it in connection with
the  redemption.  The depositary will mail notice of redemption not less than 30
and not more than 60 days  before  the date fixed for  redemption  to the record
holders of the depositary  shares we are redeeming at their addresses


                                      -18-


appearing in the  depositary's  books. The redemption price per depositary share
will be equal to the  applicable  fraction  of the  redemption  price  per share
payable with respect to the series of the preferred  stock.  The redemption date
for depositary shares will be the same as that of the preferred stock. If we are
redeeming less than all of the depositary shares, the depositary will select the
depositary  shares we are  redeeming  by lot or pro rata as the  depositary  may
determine.

     After the date  fixed for  redemption,  the  depositary  shares  called for
redemption  will no longer be deemed  outstanding.  All rights of the holders of
the  depositary  shares and the related  depositary  receipts will cease at that
time,  except  the right to  receive  the money or other  property  to which the
holders of depositary shares were entitled upon redemption. Receipt of the money
or other  property is subject to surrender to the  depositary of the  depositary
receipts evidencing the redeemed depositary shares.

Voting of the Preferred Stock

     Upon  receipt of notice of any  meeting at which the  holders of  preferred
stock  represented by depositary  shares are entitled to vote, a depositary will
be required to mail the  information  contained  in the notice of meeting to the
record  holders of the  applicable  depositary  shares.  Each  record  holder of
depositary  shares on the record date, which will be the same date as the record
date for the preferred stock,  will be entitled to instruct the depositary as to
the exercise of the voting rights  pertaining  to the amount of preferred  stock
represented  by the holder's  depositary  shares.  The  depositary  will try, as
practical,  to vote the depositary  shares as instructed by the record holder of
depositary  shares.  We will  agree  to take  all  reasonable  action  that  the
depositary deems necessary in order to enable it to do so. If a record holder of
depositary  shares does not  instruct  the  depositary  how to vote the holder's
depositary shares, the depositary will abstain from voting those shares.

Liquidation Preference

     Upon our  liquidation,  whether  voluntary or  involuntary,  each holder of
depositary shares will be entitled to the fraction of the liquidation preference
accorded each share of preferred stock represented by the depositary  shares, as
shown in the applicable prospectus supplement.

Conversion or Exchange of Preferred Stock

     The  depositary   shares  will  not  themselves  be  convertible   into  or
exchangeable for common stock, preferred stock or any of our other securities or
property. Nevertheless, if so specified in the applicable prospectus supplement,
the  depositary  receipts  may be  surrendered  by  holders  to  the  applicable
depositary with written instructions to it to instruct us to cause conversion of
the preferred  stock  represented by the  depositary  shares.  Similarly,  if so
specified in the applicable  prospectus  supplement,  we may require  holders of
depositary  shares  to  surrender  all  of  their  depositary  receipts  to  the
applicable  depositary  upon our  requiring  the  conversion  or exchange of the
preferred stock  represented by the depositary  shares into a different class of
our  securities.  We will agree that,  upon receipt of the  instruction  and any
amounts payable in connection with the conversion or exchange, we will cause the
conversion or exchange using the same  procedures as those provided for delivery
of  preferred  stock to  effect  the  conversion  or  exchange.  If a holder  of
depositary  shares  is  converting  only a part of the  depositary  shares,  the
depositary  will issue the holder a new depositary  receipt for any  unconverted
depositary shares.

Taxation

     A holder of depositary  shares will be treated for U.S.  federal income tax
purposes as if it were a holder of the series of preferred stock  represented by
the  depositary  shares.  Therefore,  the holder of  depositary  shares  will be
required to take into account for U.S.  federal  income tax purposes  income and
deductions  to which it would be entitled if it were a holder of the  underlying
series of preferred stock. In addition:

     o    no  gain or loss  will be  recognized  for  U.S.  federal  income  tax
          purposes  upon the  withdrawal  of  preferred  stock in  exchange  for
          depositary shares provided in the deposit agreement;

                                      -19-


     o    the tax basis of each share of  preferred  stock issued to a holder as
          exchanging owner of depositary shares will, upon exchange, be the same
          as the aggregate tax basis of the depositary  shares exchanged for the
          preferred stock; and

     o    if a holder held the depositary  shares as a capital asset at the time
          of the exchange for preferred  stock, the holding period for shares of
          the  preferred  stock will include the period  during which the holder
          owned the depositary shares.

Amendment and Termination of a Deposit Agreement

     We and the  applicable  depositary  are  permitted to amend the form of the
depositary  receipt and the provisions of the deposit  agreement.  However,  the
holders  of at  least  a  majority  of the  applicable  depositary  shares  then
outstanding must approve any amendment that adds or increases fees or materially
and  adversely  alters the rights of  holders.  Every  holder of an  outstanding
depositary receipt at the time any amendment becomes effective, by continuing to
hold the receipt, will be bound by the applicable deposit agreement, as amended.

     Any deposit  agreement  may be terminated by us upon not less than 30 days'
prior written notice to the  applicable  depositary if a majority of each series
of preferred stock affected by the termination consents to the termination. When
that event occurs,  the depositary will be required to deliver or make available
to each holder of depositary shares,  upon surrender of the depositary  receipts
held by the holder,  the number of whole or fractional shares of preferred stock
as are  represented  by  the  depositary  shares  evidenced  by  the  depositary
receipts,  together with any other property held by the depositary  with respect
to the depositary  shares. In addition,  a deposit agreement will  automatically
terminate if:

     o    all outstanding depositary shares have been redeemed;

     o    there shall have been a final  distribution  in respect of the related
          preferred   stock  in  connection   with  our   liquidation   and  the
          distribution  has been  made to the  holders  of  depositary  receipts
          evidencing the depositary shares underlying the preferred stock; or

     o    each  of the  shares  of  related  preferred  stock  shall  have  been
          converted or exchanged into  securities not  represented by depositary
          shares.

Charges of a Depositary

     We will pay all transfer and other taxes and  governmental  charges arising
solely from the existence of a deposit agreement.  In addition,  we will pay the
fees and expenses of a depositary in connection  with the initial deposit of the
preferred stock and any redemption of the preferred stock.  However,  holders of
depositary shares will pay any transfer taxes or other governmental  charges and
the fees and expenses of a  depositary,  including a fee for the  withdrawal  of
shares  of  preferred  stock  upon  surrender  of  depositary  receipts,  as are
expressly provided in the deposit agreement to be for their accounts.

Resignation and Removal of Depositary

     A  depositary  may  resign  at any time by  delivering  to us notice of its
election  to do so. In  addition,  we may at any time remove a  depositary.  Any
resignation  or removal will take effect when we appoint a successor  depositary
and it accepts the appointment. We must appoint a successor depositary within 60
days after delivery of the notice of resignation or removal.  A depositary  must
be a bank or trust company having its principal office in the United States that
has a combined capital and surplus of at least $50 million.

                                      -20-


Miscellaneous

     A depositary  will be required to forward to holders of  depositary  shares
any reports and  communications  that it  receives  from us with  respect to the
related  preferred stock.  Holders of depository  shares will be able to inspect
the  transfer  books of the  depository  and the list of holders  of  depositary
shares upon reasonable notice.

     Neither we nor a  depositary  will be liable if either of us are  prevented
from, or delayed in performing,  by law or any circumstances beyond our control,
our  obligations  under a deposit  agreement.  Our  obligations and those of the
depositary under a deposit agreement will be limited to performing our duties in
good faith and without gross  negligence or willful  misconduct.  Neither we nor
any depositary will be obligated to prosecute or defend any legal  proceeding in
respect of any depositary receipts, depositary shares or related preferred stock
unless  satisfactory  indemnity is  furnished.  We and each  depositary  will be
permitted to rely on written  advice of counsel or  accountants,  on information
provided  by  persons  presenting  preferred  stock for  deposit,  by holders of
depositary shares, or by other persons believed in good faith to be competent to
give the information,  and on documents believed in good faith to be genuine and
signed by a proper party.

     If a depositary receives conflicting claims,  requests or instructions from
any holders of depositary  shares,  on the one hand,  and us, on the other hand,
the depositary shall be entitled to act on the claims,  requests or instructions
received from us.

                           DESCRIPTION OF OUR WARRANTS

     This section  describes the general terms and provisions of our warrants to
acquire  our  securities  that we may issue  from time to time.  The  applicable
prospectus  supplement will describe the specific terms of the warrants  offered
through that prospectus supplement.

     We  may  issue,  together  with  any  other  securities  being  offered  or
separately,  warrants entitling the holder to purchase from or sell to us, or to
receive  from us the cash  value  of the  right to  purchase  or sell,  our debt
securities, preferred stock, depositary shares or common stock. We and a warrant
agent will enter a warrant  agreement  pursuant  to which the  warrants  will be
issued.  The warrant agent will act solely as our agent in  connection  with the
warrants and will not assume any obligation or  relationship  of agency or trust
for or with any holders or beneficial owners of warrants. We will file a copy of
the warrants and the warrant agreement with the SEC at or before the time of the
offering of the applicable  series of warrants.  A holder of our warrants should
refer to the  provisions of the  applicable  warrant  agreement  and  prospectus
supplement for more specific information.

     In  the  case  of  each  series  of  warrants,  the  applicable  prospectus
supplement will describe the terms of the warrants being offered thereby.  These
include the following, if applicable:

     o    the offering price;

     o    the number of warrants offered;

     o    the securities underlying the warrants;

     o    the exercise  price,  the amount of  securities  you will receive upon
          exercise,   the  procedure  for  exercise  of  the  warrants  and  the
          circumstances,   if  any,   that  will  cause  the   warrants   to  be
          automatically exercised;

     o    the rights, if any, we have to redeem the warrants;

     o    the date on which the warrants will expire;

     o    U.S. federal income tax consequences;

     o    the name of the warrant agent; and

                                      -21-


     o    any other terms of the warrants.

     Warrants may be exercised at the appropriate office of the warrant agent or
any other office indicated in the applicable prospectus  supplement.  Before the
exercise of warrants,  holders will not have any of the rights of holders of the
securities  purchasable  upon exercise and will not be entitled to payments made
to holders of those securities.

     The warrant  agreements may be amended or supplemented  without the consent
of the holders of the  warrants to which it applies to effect  changes  that are
not inconsistent  with the provisions of the warrants and that do not materially
and adversely affect the interests of the holders of the warrants.  However, any
amendment  that  materially  and  adversely  alters the rights of the holders of
warrants will not be effective  unless the holders of at least a majority of the
applicable warrants then outstanding  approve the amendment.  Every holder of an
outstanding  warrant at the time any amendment becomes effective,  by continuing
to hold the  warrant,  will be  bound by the  applicable  warrant  agreement  as
amended. The prospectus supplement applicable to a particular series of warrants
may provide that certain  provisions of the warrants,  including the  securities
for which they may be exercisable,  the exercise price and the expiration  date,
may not be altered without the consent of the holder of each warrant.

                   DESCRIPTION OF THE STOCK PURCHASE CONTRACTS
                          AND THE STOCK PURCHASE UNITS

     We may issue  contracts  obligating  holders to purchase from us, and us to
sell to the  holders,  a specified  number of shares of common stock at a future
date or dates, which we refer to herein as "stock purchase contracts." The price
per share of common  stock and the number of shares of common stock may be fixed
at the time the stock  purchase  contracts  are issued or may be  determined  by
reference to a specific formula set forth in the stock purchase  contracts.  The
stock purchase contracts may be issued separately or as part of units consisting
of a stock purchase contract and debt securities,  trust preferred securities or
debt obligations of third parties,  including U.S.  treasury  securities,  which
secure the  holders'  obligations  to purchase  the common stock under the stock
purchase  contracts.  We refer to these units herein as "stock purchase  units."
The stock  purchase  contracts may require  holders to secure their  obligations
thereunder in a specified manner.  The stock purchase contracts also may require
us to make periodic  payments to the holders of the stock purchase units or vice
versa, and such payments may be unsecured or refunded on some basis.

     The applicable  prospectus  supplement will describe the terms of the stock
purchase  contracts or stock purchase  units.  The description in the applicable
prospectus  supplement will not  necessarily be complete,  and reference will be
made  to the  stock  purchase  contracts,  and,  if  applicable,  collateral  or
depositary  arrangements,  relating  to the stock  purchase  contracts  or stock
purchase units.  Material U.S. federal income tax  considerations  applicable to
the stock purchase units and the stock purchase contracts will also be discussed
in the applicable prospectus supplement.

                  DESCRIPTION OF THE TRUST PREFERRED SECURITIES

     If and  when IM  Capital  Trust  issues  trust  preferred  securities,  its
declaration of trust will be replaced by an amended and restated  declaration of
trust which will  authorize its trustees to issue one series of trust  preferred
securities  and one series of trust common  securities.  The form of amended and
restated  declaration  of  trust  is filed  with  the SEC as an  exhibit  to the
registration statement of which this prospectus is a part.

     The terms of the trust preferred securities will include those stated in IM
Capital  Trust's  declaration  of trust,  as it may be amended and restated from
time to time, and those made a part of that  declaration by the Trust  Indenture
Act of 1939.  This section  describes  the general  terms and  provisions  of IM
Capital  Trust's  amended  and  restated  declaration  of  trust  and the  trust
securities  IM  Capital  Trust  may  offer  from  time to time.  The  applicable
prospectus  supplement  will  describe  the  specific  terms of the  amended and
restated declaration of trust and the trust preferred securities offered through
that prospectus supplement.  Any final amended and restated declaration of trust
will  be  filed  with  the  SEC  if IM  Capital  Trust  issues  trust  preferred
securities.  A holder of trust preferred  securities  should read the applicable
prospectus supplement and the amended and restated declaration of trust for more
specific information.

                                      -22-


     The prospectus  supplement relating to the trust preferred securities being
offered will include  specific terms relating to the offering.  These terms will
include some or all of the following:

     o    the designation of the trust preferred securities;

     o    the number of trust preferred securities to be issued;

     o    the  annual   distribution   rate  and  any   conditions   upon  which
          distributions are payable,  the distribution payment dates, the record
          dates for distribution  payments and the additional  amounts,  if any,
          that may be payable with respect to the trust preferred securities;

     o    whether  distributions  will be cumulative and compounding and, if so,
          the dates from which distributions will be cumulative or compounded;

     o    the amounts  that will be paid out of the assets of IM Capital  Trust,
          after the  satisfaction  of  liabilities  to  creditors  of IM Capital
          Trust, to the holders of trust preferred  securities upon dissolution,
          winding up or termination of IM Capital Trust;

     o    any repurchase, redemption or exchange provisions;

     o    any preference or  subordination  rights upon a default or liquidation
          of IM Capital Trust;

     o    any voting  rights of the trust  preferred  securities  in addition to
          those  required  by law,  including  the  number  of votes  per  trust
          preferred security and any requirement for the approval by the holders
          of trust preferred securities, as a condition to a specified action or
          amendments to the declaration of trust;

     o    terms for any conversion or exchange of the related series of our debt
          securities or the trust preferred securities into other securities;

     o    any rights to defer distributions on the trust preferred securities by
          extending  the interest  payment  period on the related  series of our
          debt securities;

     o    any terms and  conditions  upon which the  related  series of our debt
          securities  may  be   distributed   to  holders  of  trust   preferred
          securities; and

     o    any other relevant terms, rights, preferences, privileges, limitations
          or restrictions of the trust preferred securities.

     The  regular  trustee,  on behalf of IM Capital  Trust and  pursuant to the
declaration of trust, will issue one class of trust preferred securities and one
class  of  trust  common  securities.  The  trust  preferred  and  trust  common
securities will represent undivided beneficial ownership interests in the assets
of  IM  Capital  Trust.  Except  as  described  in  the  applicable   prospectus
supplement,  the trust preferred securities will rank equally, and payments will
be made thereon  proportionately,  with the trust common  securities.  The trust
preferred  securities  will be  issued  to the  public  under  the  registration
statement of which this  prospectus is a part. The trust common  securities will
be issued directly or indirectly to us.

     The only source of cash to make payments on the trust preferred  securities
issuable  by IM Capital  Trust will be payments  on debt  securities  IM Capital
Trust  purchases  from us. The  property  trustee of IM Capital  Trust will hold
legal title to the debt  securities IM Capital Trust  purchases in trust for the
benefit of the holders of its trust preferred securities. If IM Capital Trust is
dissolved,  after  satisfaction  of IM Capital Trust's  creditors,  the property
trustee may  distribute  the debt  securities  held in trust on a  proportionate
basis to the holders of trust preferred and trust common securities.

                                      -23-


     We will execute a guarantee agreement for the benefit of the holders of the
trust preferred securities.  The terms of our guarantee will be set forth in the
applicable   prospectus   supplement  and  are  summarized   under  the  caption
"Description of the Trust Preferred Securities  Guarantee" included elsewhere in
this  prospectus.  As discussed  below,  the  guarantee  will not  guarantee the
payment of distributions, or any amounts payable on redemption or liquidation of
the  trust  preferred  securities  when IM  Capital  Trust  does not have  funds
available to make these payments.

     In the  applicable  prospectus  supplement  we will also  describe  certain
material  U.S.  federal  income  tax  consequences  and  special  considerations
applicable to the trust preferred securities.

             DESCRIPTION OF THE TRUST PREFERRED SECURITIES GUARANTEE

     If and when IM Capital  Trust issues trust  preferred  securities,  we will
fully and unconditionally  guarantee payments on the trust preferred  securities
as described in this  section,  any  applicable  prospectus  supplement  and the
guarantee  executed by us in connection with the issuance of the trust preferred
securities.  The Bank of New York, as guarantee trustee, will hold the guarantee
for the benefit of the holders of trust preferred securities.

     This  section  describes  the  general  terms and  provisions  of our trust
preferred  securities  guarantee.  The  applicable  prospectus  supplement  will
describe the specific terms of the trust  preferred  securities  guarantee.  The
form of trust guarantee is filed with the SEC as an exhibit to the  registration
statement of which this  prospectus is a part. We will file with the SEC a final
guarantee if IM Capital  Trust issues trust  preferred  securities.  A holder of
trust preferred securities should refer to the applicable  prospectus supplement
and to the  full  text of our  guarantee,  and  those  terms  made a part of the
guarantee by the Trust Indenture Act of 1939, for more specific information.

     We will irrevocably and unconditionally  agree to pay in full to holders of
trust  preferred  securities the following  amounts to the extent not paid by IM
Capital Trust:

     o    any accumulated and unpaid  distributions  and any additional  amounts
          with  respect to the trust  preferred  securities  and any  redemption
          price for trust  preferred  securities  called  for  redemption  by IM
          Capital  Trust,  if and to the extent that we have made  corresponding
          payments on the debt securities to the property  trustee of IM Capital
          Trust; and

     o    payments upon the  dissolution of IM Capital Trust equal to the lesser
          of:

          (1)  the   liquidation   amount  plus  all   accumulated   and  unpaid
               distributions  and  additional  amounts  on the  trust  preferred
               securities  to the  extent IM  Capital  Trust  has funds  legally
               available for those payments; and

          (2)  the  amount of  assets  of IM  Capital  Trust  remaining  legally
               available  for  distribution  to the  holders of trust  preferred
               securities in liquidation of IM Capital Trust.

     We will not be required to make these liquidation payments if:

     o    IM Capital  Trust  distributes  the debt  securities to the holders of
          trust  preferred  securities  in exchange  for their  trust  preferred
          securities; or

     o    IM Capital Trust redeems the trust  preferred  securities in full upon
          the maturity or redemption of the debt securities.

     We may satisfy our obligation to make a guarantee  payment either by making
payment  directly  to  the  holders  of  trust  preferred  securities  or to the
guarantee  trustee for  remittance to the holders or by causing IM Capital Trust
to make the payment to them.

     The  guarantee is a guarantee  from the time of issuance of the  applicable
series of trust  preferred  securities.  THE  GUARANTEE  ONLY  COVERS,  HOWEVER,
DISTRIBUTIONS  AND OTHER  PAYMENTS ON TRUST


                                      -24-


PREFERRED  SECURITIES  IF AND TO THE  EXTENT  THAT  WE HAVE  MADE  CORRESPONDING
PAYMENTS ON THE DEBT SECURITIES TO THE APPLICABLE PROPERTY TRUSTEE. IF WE DO NOT
MAKE THOSE CORRESPONDING PAYMENTS ON THE DEBT SECURITIES,  IM CAPITAL TRUST WILL
NOT HAVE FUNDS  AVAILABLE  FOR PAYMENTS AND WE WILL HAVE NO OBLIGATION TO MAKE A
GUARANTEE PAYMENT.

     The obligations  under the debt securities,  the associated  indenture,  IM
Capital Trust's declaration of trust and our related guarantee,  taken together,
will provide a full and unconditional guarantee of payments of distributions and
other amounts due on the trust preferred securities.

Iron Mountain Covenants

     In the  guarantee,  we will  agree  that,  as long as any  trust  preferred
securities  issued by IM  Capital  Trust are  outstanding,  we will not make the
payments and distributions described below if:

     o    we  are  in  default  on  our  guarantee  payments  or  other  payment
          obligations under the related guarantee;

     o    any trust  enforcement  event under IM Capital Trust's  declaration of
          trust has occurred and is continuing; or

     o    we elect to defer payments of interest on the related debt  securities
          by extending the interest payment period,  and that deferral period is
          continuing.

     In these circumstances, we will agree that we will not:

     o    declare or pay any dividends or distributions on, or redeem, purchase,
          acquire,  or make a  liquidation  payment  with respect to, any of our
          capital stock; or

     o    make any payment of  principal,  interest  or  premium,  if any, on or
          repay,  repurchase  or redeem any debt  securities  that rank  equally
          with,  or junior in interest  to, the debt  securities  we issue to IM
          Capital  Trust or make any  guarantee  payments  with  respect  to any
          guarantee  by us of  the  debt  of any of  our  subsidiaries  if  that
          guarantee  ranks  equally  with or  junior  in  interest  to the  debt
          securities we issue to IM Capital Trust.

     However, even during these circumstances, we may:

     o    purchase  or  acquire  our  capital  stock  in  connection   with  the
          satisfaction  of our obligations  under any employee  benefit plans or
          pursuant to any contract or security  outstanding  on the first day of
          any extension period requiring us to purchase our capital stock (other
          than a contract or security ranking expressly by its terms on a parity
          with or junior to the debt securities);

     o    reclassify  our  capital  stock or  exchange  or convert  one class or
          series of our capital stock for another class or series of our capital
          stock;

     o    purchase fractional  interests in shares of our capital stock pursuant
          to the  conversion or exchange  provisions of our capital stock or the
          security being converted or exchanged;

     o    declare  dividends  or  distributions  in our capital  stock where the
          dividend  stock is the same  stock as that on which  the  dividend  is
          being paid;

     o    redeem, repurchase or issue any rights pursuant to a rights agreement;
          and

     o    make  payments  under the  guarantee  related  to the trust  preferred
          securities.

     In addition,  as long as trust  preferred  securities  issued by IM Capital
Trust are outstanding, we will agree that we will:

                                      -25-


     o    remain the sole direct or indirect owner of all the outstanding  trust
          common  securities  of IM Capital  Trust,  except as  permitted by its
          declaration of trust;

     o    permit  the  trust  common  securities  of  IM  Capital  Trust  to  be
          transferred only as permitted by its declaration of trust; and

     o    use  reasonable  efforts to cause IM Capital  Trust to  continue to be
          treated  as a grantor  trust for U.S.  federal  income  tax  purposes,
          except in connection  with a  distribution  of debt  securities to the
          holders of trust  preferred  securities as provided in its declaration
          of trust, in which case IM Capital Trust would be dissolved.

Amendments and Assignment

     We and the guarantee trustee may amend the guarantee without the consent of
any holder of trust  preferred  securities if the  amendment  does not adversely
affect the rights of the holders in any material respect. In all other cases, we
and the guarantee  trustee may amend the guarantee  only with the prior approval
of the holders of at least a majority of outstanding trust preferred  securities
issued by IM Capital Trust.

     We may assign our obligations under the guarantee only in connection with a
consolidation,  merger or asset sale  involving us that is  permitted  under the
indenture governing the debt securities.

Termination of the Guarantee

     Our guarantee will terminate upon:

     o    full payment of the redemption price of all trust preferred securities
          of IM Capital Trust;

     o    distribution  of the related debt  securities,  or any securities into
          which those debt  securities  are  convertible,  to the holders of the
          trust  preferred  and trust common  securities  of IM Capital Trust in
          exchange for all the securities issued by IM Capital Trust; or

     o    full  payment of the amounts  payable upon  liquidation  of IM Capital
          Trust.

     The  guarantee  will,  however,  continue  to  be  effective,  or  will  be
reinstated,  if any holder of trust preferred  securities must repay any amounts
paid on those trust preferred securities or under the guarantee.

Status of the Guarantee

     We will specify in the applicable  prospectus supplement the ranking of the
guarantee  with respect to our capital  stock and other  liabilities,  including
other guarantees.

     The guarantee will be deposited  with the guarantee  trustee to be held for
the  benefit of the holders of the trust  preferred  securities.  The  guarantee
trustee will have the right to enforce the guarantee on the holders' behalf.  In
most cases, the holders of a majority of outstanding trust preferred  securities
issued by IM Capital  Trust  will have the right to direct the time,  method and
place of:

     o    conducting any  proceeding for any remedy  available to the applicable
          guarantee trustee; or

     o    exercising  any trust or other  power  conferred  upon that  guarantee
          trustee under the guarantee.

     The  guarantee  will  constitute  a guarantee  of payment and not merely of
collection.  This  means  that  the  guarantee  trustee  may  institute  a legal
proceeding  directly  against  us  to  enforce  the  payment  rights  under  the
guarantee, without first instituting a legal proceeding against IM Capital Trust
or any other person or entity.

                                      -26-


     If the guarantee  trustee fails to enforce the guarantee or we fail to make
a guarantee payment, a holder of the trust preferred  securities may institute a
legal  proceeding  directly against us to enforce the holder's rights under that
guarantee without first instituting a legal proceeding against IM Capital Trust,
the guarantee trustee or any other person or entity.

Periodic Reports Under Guarantee

     We  will be  required  to  provide  annually  to the  guarantee  trustee  a
statement as to our  performance of our  obligations and our compliance with all
conditions under the guarantee.

Duties of Guarantee Trustee

     The guarantee trustee normally will perform only those duties  specifically
set  forth  in the  guarantee.  The  guarantee  will  not  contain  any  implied
covenants.  If a default occurs on the guarantee,  the guarantee trustee will be
required to use the same degree of care and skill in the  exercise of its powers
under  the  guarantee  as a  prudent  person  would  exercise  or use  under the
circumstances  in the conduct of his own  affairs.  The  guarantee  trustee will
exercise  any of its  rights or powers  under the  guarantee  at the  request or
direction of holders of the trust  preferred  securities  only if the  guarantee
trustee is offered security and indemnity satisfactory to it.

     RELATIONSHIP AMONG THE DEBT SECURITIES, THE TRUST PREFERRED SECURITIES
                  AND THE TRUST PREFERRED SECURITIES GUARANTEE

     To the  extent  set  forth in the  guarantee  and to the  extent  funds are
available,  we will irrevocably guarantee the payment of distributions and other
amounts due on the trust  preferred  securities.  If and to the extent we do not
make payments on the debt securities to the property  trustee,  IM Capital Trust
will not have sufficient funds to pay  distributions or other amounts due on the
trust  preferred  securities.  The  guarantee  does not  cover  any  payment  of
distributions or other amounts due on the trust preferred  securities  unless IM
Capital  Trust has  sufficient  funds for the payment of such  distributions  or
other  amounts.  In such  event,  a holder  of trust  preferred  securities  may
institute  a legal  proceeding  directly  against us to enforce  payment of such
distributions  or other amounts to such holder after the  respective  due dates.
Taken  together,  our  obligations  under the debt  securities,  the  associated
indenture,  IM Capital  Trust's  declaration of trust and our related  guarantee
will provide a full and unconditional guarantee of payments of distributions and
other amounts due on the trust preferred securities. No single document standing
alone or operating  in  conjunction  with fewer than all of the other  documents
constitutes such guarantee. It is only the combined operation of these documents
that provides a full and  unconditional  guarantee of IM Capital Trust's payment
obligations under the trust preferred securities.

Sufficiency of Payments

     As long as payments of interest and other  amounts are made when due on the
debt  securities,  such payments will be sufficient to cover  distributions  and
payments due on the trust preferred securities because of the following factors:

     o    the aggregate principal amount of the debt securities will be equal to
          the  sum of the  aggregate  stated  liquidation  amount  of the  trust
          preferred securities;

     o    the interest rate and the interest and other payment dates on the debt
          securities will match the distribution rate and distribution and other
          payment dates for the trust preferred securities;

     o    we, as issuer of the debt  securities,  will pay, and IM Capital Trust
          will not be  obligated  to pay,  directly  or  indirectly,  any costs,
          expenses,  debts and obligations of IM Capital Trust,  other than with
          respect to the trust preferred securities; and

     o    the  declaration  of trust will further  provide that IM Capital Trust
          will  not  engage  in any  activity  that is not  consistent  with the
          limited purposes of IM Capital Trust.

                                      -27-


     Notwithstanding  anything  to the  contrary in the  indenture,  we have the
right  to set off any  payment  we are  otherwise  required  to make  thereunder
against and to the extent we have already made, or are  concurrently on the date
of such payment making, a related payment under the guarantee.

Enforcement Rights of Holders of Preferred Securities

     The declaration of trust provides that if we fail to make interest or other
payments  on the debt  securities  when due,  taking  account  of any  extension
period,  the holders of the trust  preferred  securities may direct the property
trustee to enforce its rights under the  applicable  indenture.  If the property
trustee  fails to enforce its rights under the  indenture in respect of an event
of  default  under the  indenture,  any  holder  of  record  of trust  preferred
securities may, to the fullest extent  permitted by applicable law,  institute a
legal proceeding  against us to enforce the property  trustee's rights under the
indenture  without first  instituting  any legal  proceeding  against IM Capital
Trust, the property trustee or any other person or entity.  Notwithstanding  the
foregoing,  if a trust enforcement event has occurred and is continuing and such
event is  attributable  to our failure to pay interest,  premium or principal on
the debt securities on the date such interest, premium or principal is otherwise
payable,  then a holder of trust  preferred  securities  may  institute a direct
action  against us for  payment of such  holder's  pro rata  share.  If a holder
brings such a direct action,  we will be entitled to that holder's  rights under
IM Capital Trust's  declaration of trust to the extent of any payment made by us
to that holder.

     If we fail to  make  payments  under  the  guarantee,  a  holder  of  trust
preferred  securities  may  institute  a  proceeding  directly  against  us  for
enforcement of the guarantee for such payments.

Limited Purpose of Trust

     The trust preferred  securities  evidence  undivided  beneficial  ownership
interests in the assets of IM Capital Trust, and IM Capital Trust exists for the
sole  purpose  of issuing  and  selling  the trust  preferred  and trust  common
securities and using the proceeds to purchase our debt  securities.  A principal
difference  between the rights of a holder of trust  preferred  securities and a
holder  of our debt  securities  is that a  holder  of our  debt  securities  is
entitled to receive from us the  principal  amount of, and interest  accrued on,
the debt  securities  held,  while a holder  of trust  preferred  securities  is
entitled to receive  distributions  and other payments from IM Capital Trust, or
from us under the  guarantee,  only if, and to the extent,  IM Capital Trust has
funds available for the payment of such distributions and other payments.

Rights Upon Dissolution

     Upon any voluntary or involuntary dissolution of IM Capital Trust involving
the  redemption  or repayment of the debt  securities,  the holders of the trust
preferred  securities  will be  entitled  to  receive,  out of assets held by IM
Capital Trust,  subject to the rights of creditors of IM Capital Trust,  if any,
the  liquidation  distribution  in cash.  Because we are the guarantor under the
guarantee and, as issuer of the debt  securities,  we have agreed to pay for all
costs,  expenses  and  liabilities  of IM  Capital  Trust  other than IM Capital
Trust's  obligations  to the  holders  of the trust  preferred  securities,  the
positions  of a  holder  of trust  preferred  securities  and a  holder  of debt
securities  relative to other creditors and to our  stockholders in the event of
liquidation or bankruptcy of us would be substantially the same.

          DESCRIPTION OF CERTAIN PROVISIONS OF PENNSYLVANIA LAW AND OUR
                      ARTICLES OF INCORPORATION AND BYLAWS

     We are organized as a Pennsylvania corporation.  The following is a summary
of  our  articles  of  incorporation  and  bylaws  and  certain   provisions  of
Pennsylvania  law.  Because  it is a  summary,  it  does  not  contain  all  the
information  that may be  important  to you. If you want more  information,  you
should read our entire articles of incorporation and bylaws,  copies of which we
have previously  filed with the SEC, see "Where You Can Find More  Information,"
or refer to the provisions of Pennsylvania law.

     Pennsylvania law, our articles of incorporation and our bylaws contain some
provisions  that could delay or make more  difficult  the  acquisition  of us by
means of a tender  offer,  a proxy contest or otherwise.  These  provisions,

                                      -28-


as  described  below,  are  expected  to  discourage  certain  types of coercive
takeover practices and inadequate takeover bids and to encourage persons seeking
to  acquire  control  of us first to  negotiate  with us.  We  believe  that the
benefits of increased  protection of our ability to negotiate with the proponent
of an unfriendly or  unsolicited  proposal to acquire or restructure us outweigh
the  disadvantages of discouraging such proposals  because,  among other things,
negotiations  with respect to such  proposals  could result in an improvement of
their terms.

Pennsylvania Anti-Takeover Statutory Provisions

     We are subject to the anti-takeover provisions of Section 2538 and Sections
2551-2556 of the Pennsylvania  Business Corporation Law of 1988, as amended (the
"PBCL"),  which in certain cases impose restrictions on, including providing for
supermajority  shareholder approval of, business  combinations  involving us and
any "interested  shareholder."  "Interested  shareholder" includes generally, in
the  case  of  Section  2538,  shareholders  who  are a  party  to the  business
combination or who are treated differently from other shareholders,  and, in the
case of Sections 2551-2556,  shareholders beneficially owning 20% or more of the
voting  power of a  "registered"  corporation,  such as us, or an  affiliate  or
associate  of such  corporation  which,  during  the  prior  five  year  period,
beneficially owned 20% or more of the voting power of such corporation. The term
"business  combination"  is  broadly  defined to  include  various  transactions
including mergers, consolidations, asset sales and other similar transactions to
or with the interested  shareholder or with, involving or resulting in any other
corporation  which is or  would  be  after  the  transaction,  an  affiliate  or
associate of an interested shareholder.  The PBCL provides for further statutory
anti-takeover   provisions  relating  to  control  transactions,   control-share
acquisitions  and  disgorgement.   We  have  specifically  opted  out  of  these
provisions pursuant to our articles of incorporation.

     The PBCL also provides that when making decisions  concerning  takeovers or
any other matters,  the directors of a corporation  may consider,  to the extent
that they deem appropriate,  among other things, (1) the effects of any proposed
transaction upon any or all groups affected by the transaction, including, among
others, shareholders, employees, suppliers, customers, creditors and communities
in which we have offices,  (2) the  short-term  and  long-term  interests of the
corporation  and (3) the  resources,  intent and  conduct of the person  seeking
control.

Classified   Board  of  Directors  and  Other  Provisions  of  Our  Articles  of
Incorporation and Bylaws

     Our bylaws  provide that,  other than directors to be elected by holders of
any series of preferred stock, our board of directors is to be composed of three
classes,  with staggered  three-year  terms, each class to be as nearly equal in
number  as  reasonably  possible.   Accordingly,   at  each  annual  meeting  of
shareholders, only approximately one-third of the directors will be elected. The
classification of directors has the effect of making it more difficult to change
the composition of our board of directors.

     Our bylaws  provide that a vacancy on the board of  directors,  including a
vacancy  created by an  increase  in the size of the board of  directors  by the
directors,  may be filled by a majority of the remaining directors, or by a sole
remaining director, or by the shareholders,  and each person so elected shall be
a  director  to serve for the  balance  of the  unexpired  term of that class of
directors. Likewise, under the PBCL, without an unanimous vote, shareholders may
only remove  directors for cause.  These  provisions  are to ensure that a third
party would be precluded from removing  incumbent  directors and  simultaneously
gaining  control of the board of directors by filling the vacancies with its own
nominees.

     Certain other provisions of our articles of incorporation  and bylaws could
also have the  effect of  preventing  or  delaying  any change in control of us,
including:

     o    the  advance  notification  procedures  imposed  on  shareholders  for
          shareholder  nominations  of candidates for the board of directors and
          for other  shareholder  business to be  conducted at annual or special
          meetings;

     o    the absence of authority for shareholders to call special  shareholder
          meetings,  except in certain  limited  circumstances  mandated  by the
          PBCL; and

     o    the  absence of  authority  for  shareholder  action by  unanimous  or
          partial written consent in lieu of an annual or special meeting.

                                      -29-


     These   provisions,   the  classified  board  of  directors  and  statutory
anti-takeover  provisions,  could make it more  difficult  for a third  party to
acquire, or discourage a third party from seeking to acquire, control of us.

Limitation of Directors' Liability and Indemnification of Directors and Officers

     As permitted by the PBCL,  our bylaws  provide that a director shall not be
personally  liable for monetary  damages for any action taken, or any failure to
take any action,  unless the director breaches or fails to perform the duties of
his office  under the PBCL,  and the  breach or  failure to perform  constitutes
self-dealing,  willful  misconduct  or  recklessness.  These  provisions  of our
bylaws,  however,  do not apply to the responsibility or liability of a director
pursuant to any  criminal  statute,  or to the  liability  of a director for the
payment of taxes pursuant to local, state or federal law. These provisions offer
persons  who  serve on the  board of  directors  protection  against  awards  of
monetary damages for negligence in the performance of their duties.

     Our bylaws also  provide  that  directors  or officers  made a party to, or
threatened  to be made a party to, or  otherwise  involved  in, any  proceeding,
because  he or she is or was a  representative  of us or is or was  serving as a
representative of another corporation or any partnership,  joint venture, trust,
employee benefit plan or other enterprise,  on our behalf,  shall be indemnified
and held  harmless by us to the fullest  extent  permitted by  Pennsylvania  law
against all expenses,  liabilities and losses reasonably  incurred by or imposed
upon him or her, in connection with any threatened, pending or completed action,
suit  or  proceeding.  Indemnification  is not  available,  however,  if a court
determines  that the act or failure to act giving rise to the claim  constitutes
willful misconduct or recklessness.

     Pursuant to our bylaws, amending the provisions to reduce the limitation of
director's  liability or limit the right to  indemnification  requires unanimous
vote of the directors or a majority vote of the shareholders.

                              PLAN OF DISTRIBUTION

     We and IM  Capital  Trust may sell the  offered  securities  to one or more
underwriters  for public  offering and sale by them. We and IM Capital Trust may
also sell the offered  securities to investors  directly or through  agents.  We
will name any underwriter or agent involved in the offer and sale of the offered
securities in the applicable prospectus supplement.

     The distribution of offered securities may be effected from time to time in
one or more transactions at:

     o    a fixed price or varying prices;

     o    market prices prevailing at the time of sale;

     o    prices related to the market prices; or

     o    negotiated prices.

     Underwriters,  dealers and agents  participating in the distribution of the
securities may be deemed to be  underwriters,  and any discounts and commissions
received by them and any profit realized by them on resale of the securities may
be deemed to be underwriting  discounts and commissions under the Securities Act
of 1933. Underwriters, dealers and agents may be entitled, under agreements with
us and/or IM Capital Trust, to indemnification  against and contribution  toward
certain civil  liabilities,  including  liabilities  under the Securities Act of
1933, and to reimbursement by us and/or IM Capital Trust for certain expenses.

     If an  underwriter  or  underwriters  are  used  in the  offer  or  sale of
securities,  we and/or IM Capital Trust will execute an  underwriting  agreement
with the underwriters at the time of sale of the securities to the underwriters,
and the  names of the  underwriters  and the  principal  terms of our  and/or IM
Capital  Trust's  agreements  with  the  underwriters  will be  provided  in the
applicable prospectus supplement.

                                      -30-

     If we so indicate in the prospectus supplement, we and IM Capital Trust may
authorize  agents,  underwriters or dealers to solicit offers from certain types
of institutions to purchase securities from us or IM Capital Trust at the public
offering price under delayed delivery  contracts.  These contracts would provide
for payment and delivery on a specified date in the future.  The contracts would
be subject only to those conditions described in the prospectus supplement.  The
prospectus  supplement will describe the commission  payable for solicitation of
those contracts.

     Unless  otherwise  specified  in the related  prospectus  supplement,  each
series of offered  securities,  other than shares of common stock, will be a new
issue  with no  established  trading  market.  Any  shares of common  stock sold
pursuant  to a  prospectus  supplement  will be  listed  on the New  York  Stock
Exchange,  subject to official  notice of issuance.  We and IM Capital Trust may
elect to list any other series or class of offered  securities on an exchange or
on the Nasdaq National Market,  but are not obligated to do so. Any underwriters
to whom offered  securities are sold by us for public offering and sale may make
a market in those offered securities. Underwriters will not be obligated to make
any market,  however,  and may discontinue any market making at any time without
notice. No assurance can be given as to the liquidity of, or the trading markets
for, any offered securities.

     Certain of the underwriters and their affiliates may engage in transactions
with and perform  services for us in the  ordinary  course of business for which
they receive compensation.

     The  specific  terms and manner of sale of the offered  securities  will be
shown or summarized in the applicable prospectus supplement.

                       VALIDITY OF THE OFFERED SECURITIES

     Sullivan  &  Worcester  LLP,  Boston,  Massachusetts,  will  pass  upon the
validity of the debt securities,  preferred  stock,  depositary  shares,  common
stock, warrants,  guarantees, stock purchase contracts and stock purchase units.
As to certain  matters of Pennsylvania  law,  Sullivan & Worcester LLP will rely
upon an  opinion  of  Ballard  Spahr  Andrews &  Ingersoll,  LLP,  Philadelphia,
Pennsylvania.

     The validity of the trust  preferred  securities to be issued by IM Capital
Trust, and the enforceability of its declaration of trust and the creation of IM
Capital  Trust,  will be passed  upon by  Richards,  Layton  and  Finger,  P.A.,
Wilmington, Delaware.

                      NOTICE REGARDING ARTHUR ANDERSEN LLP

     Effective  June 19, 2002,  we  dismissed  Arthur  Andersen  LLP, our former
independent  auditor.  Our  audited  consolidated  financial  statements  as  of
December  31, 2001 and for the years ended  December  31, 2001 and 2000 that are
incorporated by reference in the registration statement of which this prospectus
forms a part were audited by Andersen as stated in their reports incorporated by
reference herein,  and have been so incorporated in reliance upon the reports of
such firm given upon their  authority  as experts in  auditing  and  accounting.
Andersen  has not  consented  to the  incorporation  by  reference  of its audit
reports in the registration statement of which this prospectus forms a part, and
we have dispensed with the requirement to file Andersen's consent in reliance on
Rule 437a under the  Securities  Act.  Since  Andersen has not  consented to the
incorporation by reference of their audit reports in the registration statement,
an investor's ability to seek potential  recoveries from Andersen related to any
claims that an investor may assert as a result of the work performed by Andersen
may be limited  significantly  by the lack of such  consent  and the  diminished
amount of assets of Andersen  that are or may be  available  to satisfy any such
claims.

                                     EXPERTS

              CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

     We have made and incorporated by reference statements in this document that
constitute  "forward-looking  statements" as that term is defined in the federal
securities  laws.  These  forward-looking  statements  concern  our  operations,
economic performance,  goals, beliefs,  strategies,  objectives,  plans, current
expectations and financial condition. The forward-looking statements are subject
to various known and unknown risks, uncertainties and other factors. When we use
words  such as  "believes,"  "expects,"  "anticipates,"  "estimates"  or similar
expressions, we are making forward-looking statements.

     Although  we  believe  that our  forward-looking  statements  are  based on
reasonable  assumptions,  our  expected  results may not be achieved  and actual
results may differ  materially  from our  expectations.  Important  factors that
could cause actual results to differ from  expectations  include,  among others,
those set forth below. For a more detailed  discussion of some of these factors,
please read carefully the information under "Risk Factors" beginning on page 2.

     o    changes in customer preferences and demand for our services;

     o    changes  in the  price  for  our  services  relative  to the  cost  of
          providing such services;

     o    the cost and availability of financing for contemplated growth;

     o    our ability or  inability  to complete  acquisitions  on  satisfactory
          terms and to integrate acquired companies efficiently;

     o    in the various digital  businesses on which we are embarking,  capital
          and technical  requirements will be beyond our means,  markets for our
          services will be less robust than anticipated,  or competition will be
          more intense than anticipated;

     o    the  possibility  that  business  partners  upon  whom we  depend  for
          technical  assistance or management and acquisition  expertise outside
          the United States will not perform as anticipated;

     o    changes in the political and economic environments in the countries in
          which our international subsidiaries operate; and

                                      -1-


     o    other  trends in  competitive  or economic  conditions  affecting  our
          financial   condition   or  results  of   operations   not   presently
          contemplated.

     These cautionary statements should not be construed by you to be exhaustive
and they are made only as of the date of this  prospectus.  You  should not rely
upon  forward-looking  statements except as statements of our present intentions
and of our  present  expectations,  which may or may not occur.  You should read
these  cautionary   statements  as  being  applicable  to  all   forward-looking
statements  wherever  they  appear.  We  assume  no  obligation  to  update  the
forward-looking  statements or the reasons why actual  results could differ from
those  projected  in  the  forward-looking   statements  to  reflect  events  or
circumstances after the date hereof.

                  DESCRIPTION OF OUR DIRECT STOCK PURCHASE PLAN

     The following questions and answers explain and constitute our Direct Stock
Purchase Plan, which we refer to below as the plan.

1.   WHAT IS THE PURPOSE OF THE PLAN?

     The plan is intended to provide  investors  with a simple,  convenient  and
economical method of purchasing shares of our common stock.

     In turn, the plan provides us with an economical and flexible  mechanism to
raise equity capital  through sales of our common stock. To the extent shares of
common  stock are  purchased  directly  from us under the plan,  we will receive
proceeds  that we will use for our  general  corporate  purposes.  We will  not,
however,  receive any  proceeds  from  shares of our common  stock that the plan
administrator  may  purchase,  at  our  direction,  in  the  open  market  or in
negotiated  transactions  with third parties in order to supply shares issued to
participants under the plan.

2.   WHAT FEATURES ARE AVAILABLE UNDER THE PLAN?

     The plan allows participants to:

     o    make  initial  cash  investments  in our common stock in amounts of at
          least $1,000 and up to $10,000;

     o    make  additional  cash  investments in our common stock at any time in
          amounts of at least $500 per payment and up to $10,000 per month;

     o    make additional cash  investments in excess of $10,000 per month,  but
          only after submission of a written request for waiver has been made to
          us and after we have given our written approval, which we may grant or
          refuse to grant in our sole discretion;

     o    on  investments  in excess of $10,000 that we approve,  purchase newly
          issued shares of our common stock at a discount of up to 5%, as we may
          determine from time to time in our sole discretion; and

     o    have cash  dividends,  if any, that we pay in the future on our common
          stock  automatically  reinvested  in  additional  shares of our common
          stock.

3.   WHAT ARE THE ADVANTAGES OF PARTICIPATING IN THE PLAN?

     Participants in the plan will enjoy certain benefits:

     o    You will be able to  purchase  our  common  stock  without  paying any
          brokerage  commission  and,  for  purchases  in excess of $10,000  per
          month,  potentially  at a discount of up to 5%, which discount will be
          determined at our sole discretion.

     o    Your funds will be fully invested  because the plan permits  fractions
          of shares to be credited  to your plan  account,  although  fractional
          share certificates will not be issued.

     o    You  can  be  free  of  cumbersome  safekeeping  requirements,  as our
          custodial service will safely hold your shares in book-entry form.

     o    You will have a simple way of making periodic cash  investments in our
          company, when and as you choose, in order to build your ownership over
          time and also to utilize  dollar-cost-averaging  if such  technique is
          part of your general investment strategy.

     o    You may direct the plan  administrator  to sell or  transfer  all or a
          portion of the shares held in your plan account and  therefore you may
          find the plan an  economical  way to liquidate  holdings  from time to
          time.

                                      -3-


     o    You will receive periodic  statements,  called statements of holdings,
          reflecting  all  current  activity  in your  plan  account,  including
          purchases,  sales and latest balances, which will simplify your record
          keeping.

4.   WHAT ARE THE  DISADVANTAGES OF MAKING  INVESTMENTS IN IRON MOUNTAIN THROUGH
     THE PLAN?

     The plan may present certain  disadvantages to a participant as compared to
investing in our company through a brokerage firm:

     o    We may, without giving you prior notice,  change our  determination as
          to whether the plan administrator will purchase shares of common stock
          directly  from  us,  in the open  market  or in  privately  negotiated
          transactions from third parties.

     o    You will not know the actual  number of shares  purchased in any month
          for your account under the plan until after the applicable  investment
          date.

     o    Because  the  investment  price may  represent  an average of numerous
          market  prices,  it may  actually  exceed the price at which you could
          have purchased shares in the open market on the investment date.

     o    Sales of shares for  participants  that have made valid sale elections
          are made daily when  practicable,  at specified  times and in a manner
          designed not to disrupt the market for our common stock.  Accordingly,
          you may  experience  delays in the  execution  of sales of your shares
          held in the plan.

     o    On purchases in excess of $10,000 that we approve, you may not be able
          to depend on the  availability  of a discount on newly  issued  shares
          acquired under the plan.  While a discount from market prices of up to
          5% may be  established  for a  particular  period,  a discount for one
          period will not ensure the  availability  of the same  discount or any
          discount in future periods.  For any period we may, without giving you
          prior notice, change or eliminate the discount.

     o    Shares  deposited in a plan account may not be pledged.  If you desire
          to pledge shares  deposited in a plan  account,  you must withdraw the
          shares from the plan.

     o    You will not receive interest on funds held by the plan  administrator
          pending investment or on funds returned if we suspend or terminate the
          plan or if your  investment  does not meet our  minimum  threshold  or
          exceeds $10,000 and is not approved.

5.   WHO WILL ADMINISTER THE PLAN?

     The  plan  will  be   administered   by  EquiServe   Trust  Company,   N.A.
("EquiServe"),  a federally  chartered trust institution,  or any successor plan
administrator  we  designate.  EquiServe,  Inc., an affiliate of EquiServe and a
transfer agent registered with the Securities and Exchange  Commission,  acts as
service  agent  for  EquiServe.   The  plan  administrator  acts  as  agent  for
participants,  keeps  records of the  accounts of  participants,  sends  regular
account  statements to  participants,  and performs other duties relating to the
plan.  Shares purchased for each participant  under the plan will be held by the
plan  administrator and will be registered in the name of the plan administrator
or its nominee, unless and until a participant requests that a stock certificate
for all or part of such  shares  be  issued,  as more  fully  described  in this
prospectus. Correspondence with the plan administrator should be sent to:

                           Iron Mountain Incorporated
                           c/o EquiServe Trust Company, N.A.

6.   WHO IS ELIGIBLE TO PARTICIPATE IN THE PLAN?

     Our existing  shareholders,  as well as persons  seeking to purchase  their
first shares in our company, may participate in the plan.

     A registered holder, which means a shareholder whose shares of common stock
are registered in our stock  transfer books in his or her name, may  participate
in the plan directly. A beneficial owner, which means a shareholder whose shares
are registered in our stock transfer books in a name other than his or her name,
for example, in the name of a broker, bank, or other nominee, must either become
a registered holder by having the shares  transferred into his or her name, make
arrangements with his or her broker, bank or other nominee to participate in the
plan on the participant's  behalf, or follow procedures for interested investors
who are not already shareholders.

     An interested  investor that is not currently a shareholder may participate
in the plan by making an initial cash investment in our common stock of not less
than $1,000 and not more than $10,000.  In some  circumstances,  however, we may
permit greater optional cash investments if an appropriate request for waiver is
filed with us and accepted.

     The right to participate in the plan is not transferable to another person.
We reserve the right to exclude from  participation  in the plan persons who use
the plan to engage in short-term  trading  activities that cause  aberrations in
the  trading of our common  stock.  In  addition,  we reserve the right to treat
optional cash investments submitted with forms reflecting  participants with the
same name,  address or social  security or taxpayer  identification  number as a
single investment for purposes of determining  whether the maximum investment of
$10,000 per month would be exceeded.

     If you live  outside  the  United  States  and are not a  citizen,  you can
participate  in the  plan  provided  there  are  not any  laws  or  governmental
regulations  that would prohibit your  participation in the plan. We reserve the
right to  terminate  participation  of any  shareholder  if we deem it advisable
under any foreign laws or  regulations.  All plan funds must be in United States
dollars and drawn on a United States  financial  institution.  If you are not in
the United States, please contact your financial institution to verify that they
can  provide  you with a check that  clears  through a United  States  financial
institution and can print the dollar amount in United States dollars. Due to the
longer  clearing  period,  we are  unable  to  accept  checks  clearing  through
non-United  States financial  institutions.  Please contact your local financial
institution for details on how to make the transaction. If we ever pay dividends
to shareholders, all dividends will be subject to withholding under the terms of
any  applicable  tax  treaty  provisions.  Please  see  Questions  9 and  13 for
additional information on dividend reinvestment.

     Participants residing in jurisdictions,  foreign or United States, in which
their  participation  in the plan  would be  unlawful  will not be  eligible  to
participate in the plan.

7.   HOW DOES AN ELIGIBLE PERSON PARTICIPATE IN THE PLAN?

     A person may participate in the plan by following the appropriate procedure
set forth below.

Our Registered Holders

     If you are a registered  holder of our common stock,  you may enroll in the
plan and become a participant by:

     o    completing and signing a shareholder authorization form; and

     o    returning  it to the plan  administrator  at the  address set forth in
          Question 5.

                                      -5-


     Please note,  that if the shares you currently  own are  registered in more
than one name, for example, joint tenants or trustees, all registered holders of
such shares must sign the shareholder  authorization form exactly as their names
appear on the account registration.

     Registered  holders may obtain  additional  information  and the  necessary
shareholder  authorization form at any time by contacting the plan administrator
at the address or phone number set forth in Question 5.

Our Beneficial Owners

     If you are a  beneficial  owner  of our  common  stock  and you  desire  to
participate in the plan, you must:

     o    instruct the registered holder who holds the shares of common stock on
          your behalf, usually a broker, bank or other nominee, to have all or a
          portion of those shares  registered  directly in your name.  You would
          then follow the procedures described above for registered holders; or

     o    make  arrangements   with  the  broker,   bank  or  other  nominee  to
          participate in the plan on your behalf.

     Alternatively,  a  beneficial  holder  may  enroll  in the plan in the same
manner  as  someone  who is not  currently  an owner  of our  common  stock,  as
described  in  the  procedures  below  for  interested  investors.   Some  state
securities laws require that a registered  broker-dealer send the information to
their residents. A registered broker-dealer, rather than the plan administrator,
will forward a copy of this  prospectus and the enrollment  form to residents of
those states.

Interested Investors Who Do Not Currently Own Our Common Stock.

     An interested  investor who is not presently one of our  shareholders,  but
desires to become a participant in the plan by making an initial cash investment
in our common stock, may join the plan by:

     o    completing and signing an initial purchase form; and

     o    forwarding it, together with a check in the amount of the initial cash
          investment  of at least  $1,000 and not more than  $10,000,  unless an
          appropriate  waiver  is  filed  with  us and  accepted,  to  the  plan
          administrator at the address set forth in Question 5.

     Any offer to make an initial cash  investment  greater than $10,000 must be
made in accordance  with the procedures  described below in Question 17. Initial
cash  investments  can be made by check  payable to  "EquiServe - Iron  Mountain
Incorporated."  All forms of payment must be in United States  dollars and drawn
on a United States bank. Cash, money orders,  and third party checks will not be
accepted.  Investments  in excess of $10,000 and  approved by us must be made by
wire transfer as described below in Question 17.

     Interested  investors may obtain  additional  information and the necessary
initial  purchase form at any time by contacting the plan  administrator  at the
address or phone  number set forth in  Question  5. Some state  securities  laws
require that a registered broker-dealer send the information to their residents.
A registered broker-dealer,  rather than the plan administrator,  will forward a
copy of this prospectus and the enrollment form to residents of those states.

8.   WHAT IS THE PURPOSE AND EFFECT OF COMPLETING AND FORWARDING THE SHAREHOLDER
     AUTHORIZATION FORM AND THE INITIAL PURCHASE FORM?

     The  shareholder  authorization  form and the  initial  purchase  form will
appoint the plan  administrator as your agent for purposes of your participation
in the plan. The forms direct the plan  administrator to apply any optional cash
investments made by you, whether transmitted with the shareholder  authorization
form, the initial  purchase form or made at dates subsequent to your enrollment,
to the purchase on your behalf of additional  full and fractional  shares of our
common stock in accordance with the plan.

9.   CAN PLAN PARTICIPANTS REINVEST THE DIVIDENDS, IF ANY, ON THEIR COMMON STOCK
     THROUGH THE PLAN?

     The  shareholder  authorization  form and the initial  purchase  form allow
participants to provide for the  reinvestment of dividends,  if any, through the
following options (in all cases minus any applicable withholding tax):

                                      -6-

     o    Full  dividend  reinvestment.  This  option  allows  you  to  reinvest
          automatically all cash dividends  received on all shares of our common
          stock registered in your name and/or held in your plan account.

     o    Partial dividend reinvestment.  This option allows you to receive cash
          dividends  on a specified  number of full  shares of our common  stock
          registered  in your  name  and/or  held in your  plan  account  and to
          reinvest  automatically  only the dividends on any remaining shares of
          common stock.

     o    No  dividend  reinvestment.  This  option  allows you to receive  cash
          dividends  on all shares of our common stock  registered  in your name
          and/or held in your plan account.  None of your cash dividends will be
          reinvested.

     Any one of the above three  options  may be  selected.  In each case,  cash
dividends, if any, will be reinvested on all shares designated for participation
in the plan until the participant specifies otherwise or withdraws from the plan
altogether,  or until  the plan is  terminated.  Participation  in the  dividend
reinvestment  portion of the plan will commence  with the next dividend  payment
date after the plan administrator  receives your shareholder  authorization form
or  initial  purchase  form,  as  the  case  may  be,  provided  that  the  plan
administrator receives the form on or prior to the record date for such dividend
payment.   If  the  plan   administrator   does  not  receive  your  shareholder
authorization form or initial purchase form on or prior to the record date for a
particular dividend payment,  participation in the dividend reinvestment portion
of the plan may not commence until the following dividend payment date.

     A participant may change his or her dividend  reinvestment  election at any
time by contacting the plan administrator.  Changes in the dividend reinvestment
election will be effective for a particular  dividend  payment date provided the
request is received  prior to the related  dividend  record date. If a change in
the dividend reinvestment election is not received prior to the related dividend
record  date,  the change will not be  effective  until the  following  dividend
payment date.

     Notwithstanding our discussion of your ability to reinvest dividends, it is
unlikely that we will pay cash dividends in the  foreseeable  future and nothing
in this prospectus is intended to indicate otherwise.

     Any participant who returns a properly executed  shareholder  authorization
form or  initial  purchase  form to the plan  administrator  without  electing a
dividend  reinvestment  option will be enrolled as having selected full dividend
reinvestment.

10.  WHAT ARE THE EXPENSES OF THE PLAN, AND WHO PAYS THEM?

     We  will  pay  all  fees,  brokerage  commissions,   and  related  expenses
associated with the purchase of common stock in the open market or in negotiated
transactions  with third parties on behalf of participants.  Shares for the plan
purchased  directly from us will not involve  brokerage  commissions  or trading
fees.  There is,  however,  a one-time  enrollment  fee of $10.00  which will be
deducted from the initial investment of interested investors who are not already
shareholders of Iron Mountain.

     In the event that any form of payment is  returned  unpaid for any  reason,
such as a returned check,  the participant will be subject to a $25.00 fee which
will be deducted from the  participant's  plan  account.  This fee and any other
incidental costs associated with the insufficient funds will be collected by our
plan administrator through the sale of an appropriate number of shares from your
plan account.

     In addition, participants that request the sale of any of their shares held
in the plan must pay a service fee equal to $15.00 per sale,  plus a  commission
currently  equal to $0.12 per share  sold plus any  applicable  taxes.  The plan
administrator   may  effect  any  sales  of  shares  for  the  plan   through  a
broker-dealer,  in which case the broker-dealer  will receive the commission for
effecting the transaction.

     The plan administrator may also charge participants for additional services
not provided under the plan.  Brokers or nominees that  participate on behalf of
beneficial  owners for whom they are holding  shares may charge such  beneficial
owners additional fees in connection with such participation,  for which neither
the plan administrator nor we will be responsible.

     Participation  in the plan is voluntary and a participant  may  discontinue
his or her participation at any time.

                                      -7-


11.  WHAT ARE THE SOURCES OF SHARES PURCHASED UNDER THE PLAN?

     Purchases  of  shares of our  common  stock by the plan  administrator  for
participants in the plan may be made, at our election,  either (1) directly from
us out of our authorized but unissued  shares of common stock or treasury stock,
or (2) in the open market or in negotiated transactions with third parties.

12.  WHEN ARE SHARES PURCHASED UNDER THE PLAN; WHAT IS THE INVESTMENT DATE?

     Purchases of shares of common stock made with  initial cash  payments  from
enrolling  investors and with  optional cash payments from current  shareholders
will  begin on an  investment  date which will be the 1st and 15th of each month
(if this  date is not a trading  day on the New York  Stock  Exchange,  then the
investment  date will be the next trading day),  except that an investment  date
for  investments  in excess of $10,000  pursuant to requests  for waiver that we
have approved  will occur only once a month,  if at all, on a day that we set at
the beginning of the month, which will be the end of the pricing period for such
month.

     The plan  administrator  will use cash  investments  to purchase  shares of
common stock during the relevant investment period. Purchases may be made over a
number of days to meet the requirements of the plan. No interest will be paid on
funds held by the plan administrator pending investment.  The plan administrator
may  commingle  your  funds  with  those of other  participants  in the plan for
purposes of executing purchase transactions.

     Because the plan  administrator will purchase shares on behalf of the plan,
neither we nor any participant in the plan has the authority or power to control
either the timing or pricing of the shares purchased. Therefore, you will not be
able to precisely  time your  purchases  through the plan, and you will bear the
market risk associated with  fluctuations in the price of our common stock. That
is, if you send in an  investment,  it is possible  that the market price of our
common  stock  could go up or down  before the plan  administrator  arranges  to
purchase stock with your funds.

     For investments that do not exceed $10,000, the plan administrator will use
its best  efforts to apply all funds to the  purchase of shares  before the next
investment  date,  subject to any  applicable  requirements  of federal or state
securities  laws.   Purchases  of  our  shares  of  common  stock  by  the  plan
administrator  on the open  market  or in  negotiated  transactions  with  third
parties  usually will be  completed  no later than 30 days after the  applicable
investment  date,  except  where  completion  at a later  date is  necessary  or
advisable  under  any  applicable  securities  laws  or  regulations;  provided,
however,  investments  under  $10,000  that are not  invested  within 35 days of
receipt will be returned. Shares of common stock purchased on the open market or
in negotiated  transactions with third parties will be credited to participating
accounts as soon as practicable  after all purchases for the investment date are
completed. Shares issued and sold by us will be credited on the investment date.

     Pursuant to an approved  request for waiver,  the plan  administrator  will
only acquire  shares of common stock  directly from us out of our authorized but
unissued  shares of common  stock or treasury  shares.  Newly  issued  shares or
treasury  shares  purchased  with  investments  over  $10,000  will be posted to
participants'  accounts  as of  the  investment  date  determined  by us at  the
beginning of each month.

     If dividends are declared at some time in the future,  the investment  date
for the  reinvestment  of dividends will be the dividend  payment date, (if this
date is not a trading day on the New York Stock  Exchange,  then the  investment
date will be the next trading day).  Purchases  with dividend  investments  will
begin on the  investment  date.  Newly issued shares or treasury  shares will be
posted to  participants'  accounts as of the  investment  date.  Purchases  with
dividend investments in the open market or in negotiated transactions with third
parties,  however, will be posted to participants' accounts after the settlement
period.  Settlement  normally occurs three business days after the investment is
completed.  Dividends that are not invested  within 30 days of the dividend date
will be paid to the participant.

     The  plan   administrator   must  receive  cash  investments,   other  than
investments  pursuant to requests for waiver,  no later than two  business  days
before the  investment  date for those  investments to be invested in our common
stock beginning on that investment date.  Otherwise,  the plan administrator may
hold those funds and invest  them  beginning  on the next  investment  date.  No
interest  will  be  paid  on  funds  held  by  the  plan  administrator  pending
investment.  Accordingly,  you may wish to transmit any investments so that they
reach the plan  administrator  shortly -- but not less than two business days --
before the investment date. This will minimize the time period during which your
funds are not invested.  Participants have an unconditional  right to obtain the
return of any cash payment up to two business days prior to the investment  date
by sending a written request to the plan administrator.

                                      -8-


     Please  note  that  participants  will  not be able to  instruct  the  plan
administrator to purchase shares at a specific time or at a specific price.

13.  HOW  IS  THE  PRICE   DETERMINED  FOR  SHARES  ACQUIRED   THROUGH  DIVIDEND
     REINVESTMENT?

     The plan will acquire shares for  participants who have elected to reinvest
all or a portion of their  dividends if, at some time in the future,  a dividend
is declared by our board of  directors.  Purchases of shares of our common stock
through the  reinvestment of dividends,  if any are declared,  will begin on the
investment  date. The purchase price of shares acquired through the plan through
the reinvestment of dividends will be equal to:

     o    in the case of newly  issued  shares or treasury  shares of our common
          stock, the average of the high and low sale prices of our common stock
          as reported  by the New York Stock  Exchange-only,  on the  investment
          date. If no trading is reported for the investment  date, the purchase
          price will be equal to the  average of the high and low sale prices of
          our common stock as reported by the New York Stock  Exchange-only,  on
          the trading day immediately prior to the investment date; or

     o    in the case of shares  purchased  in the open  market or in  privately
          negotiated  transactions,  the  weighted  average  price of all shares
          purchased with the dividend funds.

14.  WHAT LIMITATIONS AND EXCEPTIONS APPLY TO OPTIONAL CASH INVESTMENTS?

Minimum/Maximum Limits

     For any investment date, optional cash investments made by our shareholders
are  subject  to a minimum  of $500 per  payment.  In  addition,  optional  cash
investments by our  shareholders  are subject to a maximum of $10,000 per month,
unless a request for waiver has been approved as described below.  Optional cash
investments  made by interested  investors who are not then  shareholders of our
company are subject to a minimum  initial  investment of $1,000 and a maximum of
$10,000, unless a request for waiver has been approved.

     Optional cash  investments  of less than the allowable  minimum  amount and
that portion of any optional cash investment that exceeds the allowable  monthly
maximum   amount  will  be  returned,   except  as  noted  below,   promptly  to
participants, without interest. Optional cash investments submitted by brokerage
firms or other  nominees  on  behalf  of a  participant  may be  aggregated  for
purposes of determining whether the $10,000 limit will be exceeded. In addition,
we reserve  the right to treat  optional  cash  investments  submitted  on forms
reflecting  participants  with the same  name,  address  or social  security  or
taxpayer  identification number as a single investor for purposes of determining
whether the $10,000 limit would be exceeded. Please note that dividend funds, if
any, will not be combined with optional cash investments in determining  whether
the $10,000 limit has been exceeded.

15.  HOW ARE INVESTMENTS FOR $10,000 OR LESS MADE?

     All  participants,  including  brokers,  banks and nominees with respect to
shares registered in their name on behalf of beneficial  owners, are eligible to
make optional cash investments at any time. Other interested  investors that are
not shareholders of our company are also eligible to make initial investments in
our common stock at any time by  submitting  an initial  purchase form and funds
representing their desired initial investments.

     The plan  administrator  will apply all investments under $10,000 per month
by check,  for which good funds are received at least two  business  days before
the  investment  date for those  investments  to be invested in our common stock
beginning  on that  investment  date.  If good  funds are  received  by the plan
administrator by checks after this deadline, they will not be invested until the
next  following  investment  date. No interest will be paid on any funds pending
investment.  All optional cash investments are subject to collection by the plan
administrator for full face value in United States dollars.

     Newly  issued  shares or treasury  shares  will be posted to  participants'
accounts  as of  the  investment  date.  Purchases  in  the  open  market  or in
negotiated  transactions  with  third  parties,   however,  will  be  posted  to
participants'  accounts after the settlement period.  Settlement normally occurs
three business days after the investment is completed.

     There is no obligation to make an optional cash investment at any time, and
the amount of such investments may vary from time to time.

     All optional cash investments made by check should be made payable to:

                    "EquiServe - Iron Mountain Incorporated"

                                      -9-


and mailed to the plan  administrator,  along with the cash  investment or other
transaction  form attached to the bottom of each  statement of holdings,  at the
address  listed  on the  form.  Due to the  longer  clearance  period,  the plan
administrator  is unable to accept checks  clearing  through  non-United  States
banks.  Any checks not drawn on a United  States  bank or not  payable in United
States  dollars  will be returned to the  participant,  as will any cash,  money
order or third party checks.  If you are not in the United States,  contact your
bank to verify  that they can  provide  you with a check that  clears  through a
United States bank and can print the dollar  amount in United States funds.  All
inquiries should be directed to the plan  administrator as set forth in Question
5.

     In the event that any form of payment is  returned  unpaid for any  reason,
the plan  administrator  will consider the request for  investment of such funds
null  and void and  shall  immediately  remove  from the  participant's  account
shares,  if any,  purchased  upon  the  prior  credit  of such  funds.  The plan
administrator  shall  then be  entitled  to sell  those  shares to  satisfy  any
uncollected  amounts.  If the net  proceeds  of the  sale of  these  shares  are
insufficient  to  satisfy  the  balance  of the  uncollected  amounts,  the plan
administrator  shall  be  entitled  to sell  such  additional  shares  from  the
participant's  account necessary to satisfy the uncollected balance. Any deposit
returned  unpaid will be subject to a $25.00 fee that will be deducted  from the
participant's account, as described above in Question 10.

16.  HOW IS THE PRICE DETERMINED FOR INVESTMENTS OF $10,000 OR LESS?

     Each  month the plan will  acquire  shares for  participants  who have made
valid and timely cash investments during that month.

     The  purchase  price  of  shares  acquired   through  the  plan  with  cash
investments of $10,000 or less during any month will be equal to:

     o    in the case of newly  issued  shares or treasury  shares of our common
          stock, the average of the high and low sale prices of our common stock
          as  reported  by the New York Stock  Exchange-only  on the  investment
          date.  If no trading is reported  for that  trading  day, the purchase
          price will be equal to the  average of the high and low sale prices of
          our common  stock as reported by the New York Stock  Exchange-only  on
          the trading day immediately prior to the investment date; or

     o    in the case of shares  purchased  in the open  market or in  privately
          negotiated  transactions,  the  weighted  average  price of all shares
          purchased.

17.  HOW ARE INVESTMENTS IN EXCESS OF $10,000 MADE?

     Investments  in excess of $10,000 per month may be made only  pursuant to a
request for waiver accepted by us.

     Participants may ascertain whether we are accepting  requests for waiver in
any given  month,  and  certain  other  important  information,  by  telephoning
Investor  Relations on the first business day of each month at (617) 535-4799 or
such  other  number as we may  establish  from time to time.  When  participants
telephone  Investor  Relations on the first business day of each month,  we will
inform such participants of one of the three following pieces of information:

     (1) that we will not be accepting requests for waiver that month; or

     (2) that we will be accepting  requests  for waiver that month.  If this is
the case, we will either (a) provide  relevant  information such as the date the
pricing  period  will  begin;  the  number of days in the  pricing  period;  the
threshold  price,  if any;  the waiver  discount,  if any;  and  whether we have
established a reverse auction  procedure,  or (b) inform  participants of a date
later in the month when they can call to obtain this relevant information; or

     (3) that we have not yet determined  whether we will be accepting  requests
for waiver. If this is the case, we will inform  participants of a date later in
the month  when they can call to  inquire  as to  whether  we will be  accepting
requests for waiver.

     We will decide  whether to accept  requests  for waiver at least three days
prior to the  commencement  of the  applicable  pricing  period,  as is  further
explained in Question 18.

     We must receive a request for waiver no later than 2:00 p.m., New York City
time,  on the third  business day before the first day of the  relevant  pricing
period.  Participants who wish to make an investment in excess of $10,000 in any
given month,  including those whose proposed investments have been aggregated so
as to exceed


                                      -10-


$10,000, must obtain our prior written approval, which will be given or rejected
on or before  the  second  business  day  prior to the first day of the  pricing
period,  and a copy of such written approval must accompany any such investment.
Good funds for such investments  exceeding $10,000 per month must be received by
the plan  administrator no later than one business day prior to the first day of
the pricing period. To obtain a request for waiver or additional information,  a
participant may call Investor Relations at the number above.  Completed requests
for waiver should be faxed  directly to Investor  Relations at (617) 535-7881 or
such other number as we may establish from time to time.

     We also  may make  the  foregoing  information  available  on the  Investor
Relations  segment of our website at  http://www.ironmountain.com  or on another
website as we may establish for this purpose from time to time.  The website may
also contain a form for submitting a request for waiver via electronic mail.

     We have sole  discretion to grant any approval for investments in excess of
the  allowable  maximum  amount.  In  deciding  whether to approve a request for
waiver, we will consider relevant factors including, but not limited to:

     o    whether the plan is then  purchasing  newly issued  shares or treasury
          shares of our  common  stock,  or is  purchasing  shares of our common
          stock in the open market,

     o    our need for additional funds,

     o    the attractiveness of obtaining such additional funds through the sale
          of our common stock as compared to other sources of funds,

     o    the purchase price likely to apply to any sale of common stock,

     o    the participant submitting the request,

     o    the extent and nature of such participant's prior participation in the
          plan,

     o    the number of shares held of record by such participant, and

     o    the aggregate amount of optional cash investments in excess of $10,000
          for which requests for waiver have been submitted by all participants.

     If  requests  for  waiver  are  submitted  for any  investment  date for an
aggregate  amount in excess of the amount we are then willing to accept,  we may
honor such requests in order of receipt, pro rata or by any other method that we
determine, in our sole discretion, to be appropriate.

     We reserve the right to modify,  suspend or terminate  participation in the
plan by otherwise eligible registered holders or beneficial owners of our common
stock for any reason whatsoever, including elimination of practices that are not
consistent with the purposes of the plan.

18.  HOW IS THE PRICE  DETERMINED FOR INVESTMENTS IN EXCESS OF $10,000  PURSUANT
     TO A REQUEST FOR WAIVER?

Pricing Period and Purchase Price Determination

     The  trading  period  over which the  investment  price is  calculated  for
purchases  in excess of $10,000 per month is referred to as the pricing  period.
You may ascertain  all relevant  information  regarding  the pricing  period and
purchase price determination by telephoning Investor Relations at (617) 535-4799
or at such other number as we may  establish  from time to time, as is explained
in Question 17.

     The purchase  price of shares of our common stock  purchased  pursuant to a
request for waiver will be the volume weighted average price of our common stock
reported by the New York Stock Exchange-only, from Bloomberg, LP for the trading
hours from 9:30 a.m.  to 4:00 p.m.,  New York City time,  for each  trading  day
during the relevant  pricing  period,  less any  applicable  waiver  discount as
described below,  calculated pro rata on a daily basis.  For example,  if a cash
investment of $10 million is made pursuant to an approved request for waiver for
a pricing period of 10 trading days, the number of shares will be calculated for
each day of the  pricing  period by taking a pro rata  portion of the total cash
investment for each day of the pricing  period,  which would be $1 million,  and
dividing it by the volume weighted average price of our common stock reported by
the New York Stock

                                      -11-


Exchange-only, obtained from Bloomberg, LP, (unless such service is unavailable,
in which case we will  designate  another  service to be  utilized  prior to the
beginning of the pricing period) rounded to three decimal places,  if necessary,
for the trading hours from 9:30 a.m. to 4:00 p.m., New York City time,  less any
applicable  discount.  On the last day of the pricing period,  or the investment
date, the total  investment  amount,  $10 million,  will be divided by the total
number of shares acquired over the 10 days (assuming the threshold price is met)
in order to establish the purchase price.

     The plan administrator will apply all investments  pursuant to requests for
waiver that are approved by us and that are  received by the plan  administrator
on or before the first business day before the first day of the relevant pricing
period to the purchase of shares of our common stock on the  investment  date we
set at the  beginning  of the  month  for such  approved  investments.  All such
investments  received  after the close of  business  on the first  business  day
before the first day of the  relevant  pricing  period will be returned  without
interest.

Optional Pricing Period Extension Feature

     We may elect to activate for any given  pricing  period the pricing  period
extension  feature  which will provide that the initial  pricing  period will be
extended by the number of days that the threshold price is not satisfied,  or on
which  there are no trades of our common  stock  reported  by the New York Stock
Exchange-only,  subject  to a maximum of five days.  If the  threshold  price is
satisfied  for any  additional  day that has been added to the  initial  pricing
period,  that day will be included  as one of the  trading  days for the pricing
period in lieu of the day on which the threshold  price was not met or trades of
our common stock were not  reported.  For  example,  if the  determined  pricing
period is 10 consecutive business days, and the threshold price is not satisfied
for  three out of those 10 days in the  pricing  period,  and we had  previously
announced at the time of the waiver request acceptance that the optional pricing
period   extension   feature  was  activated,   then  the  pricing  period  will
automatically  be extended,  and if the threshold price is satisfied on the next
three trading days, then those three days will be included in the pricing period
in lieu of the three days on which the threshold price was not met. As a result,
the  purchase  price will be based upon the 10 trading  days of the  initial and
extended  pricing  period on which the threshold  price was satisfied and all of
the optional cash investment will be invested (rather than 30% being returned to
the  participant).   Participants  may  ascertain  whether  the  pricing  period
extension feature has been activated for any given pricing period by telephoning
Investor Relations at (617) 535-4799 or at such other number as we may establish
from time to time, at the conclusion of the original pricing period.

Threshold  Price with  Respect to Optional  Cash  Investments  Made  Pursuant to
Requests for Waiver

     We may establish  for any pricing  period a threshold  price  applicable to
investments  made pursuant to requests for waiver.  At least three business days
prior to the first  day of the  applicable  pricing  period,  we will  determine
whether to establish a threshold price and, if a threshold price is established,
its amount, and will so notify the plan  administrator.  This determination will
be  made  by us in  our  sole  discretion  after  a  review  of  current  market
conditions,  the level of  participation  in the plan, and current and projected
capital needs. Participants may ascertain whether a threshold price has been set
or  waived  for  any  given  pricing  period  and  any  applicable  discount  by
telephoning  Investor  Relations at (617) 535-4799 or at such other number as we
may establish from time to time, as is explained in Question 17.

     If established for any pricing  period,  the threshold price will be stated
as a dollar  amount that the volume  weighted  average price of our common stock
reported  by the New York  Stock  Exchange-only,  obtained  from  Bloomberg,  LP
(unless such service is  unavailable,  in which case we will  designate  another
service to be utilized  prior to the  beginning  of the pricing  period) for the
trading hours from 9:30 a.m. to 4:00 p.m., Eastern Time, must equal or exceed on
each trading day of the relevant pricing period. In the event that the threshold
price is not satisfied  for a trading day in the pricing  period or there are no
trades of our common stock  reported by the New York Stock  Exchange-only  for a
trading day, then that trading day will be excluded from the pricing period with
respect to optional cash investments  made pursuant to requests for waiver,  and
all trading prices for that day will be excluded from the  determination  of the
purchase price. For example,  if the threshold price is not satisfied for two of
the 10 trading days in a pricing  period,  then the purchase price will be based
upon  the  remaining  eight  trading  days on  which  the  threshold  price  was
satisfied, unless we have activated the pricing period extension feature for the
pricing period as described  above under  "--Optional  Pricing Period  Extension
Feature."

     In  addition,  a pro rata  portion of each  investment  made  pursuant to a
request for waiver will be returned for each trading day of a pricing  period on
which the  threshold  price is not satisfied or for each trading day on which no
trades  of  shares  or  common   stock  are  reported  on  the  New  York  Stock
Exchange-only,  as soon as  reasonably  practicable  after  the  pricing  period
without interest,  subject to the effect of an optional pricing period extension

                                      -12-


feature as described above under "--Optional  Pricing Period Extension Feature."
The returned amount will equal the total amount of the investment  multiplied by
a  fraction,  the  numerator  of which is the  number of  trading  days that the
threshold  price is not satisfied or trades of our common stock are not reported
on the New York Stock  Exchange-only  and the denominator of which is the number
of trading days in the pricing  period.  For example,  if the threshold price is
not  satisfied  or if no sales  are  reported  for one of 10  trading  days in a
pricing period,  one-tenth of the optional investment will be returned. All such
funds will be  returned  as soon as  reasonably  practicable  after the  pricing
period without interest.

     The  establishment  of the  threshold  price and the  possible  return of a
portion  of the  investment  applies  only to  optional  cash  investments  made
pursuant  to a request  for  waiver  but  applies  to the  entire  amount of the
optional cash investment, including the first $10,000. Setting a threshold price
for a pricing  period shall not affect the setting of a threshold  price for any
subsequent  pricing period.  We may waive our right to set a threshold price for
any pricing period.  Neither we nor the plan  administrator  will be required to
provide any written  notice to  participants  as to the threshold  price for any
pricing period.  Participants may, however,  ascertain whether a threshold price
has been set or waived for any given pricing period and any applicable  discount
by telephoning  Investor  Relations at (617) 535-4799 or at such other number as
we may establish from time to time.

Waiver Discount

     We may, in our sole discretion,  establish a "waiver  discount" of 0% to 5%
from the market  price  applicable  to  optional  investments  made  pursuant to
requests for waiver. The waiver discount will not vary for any pricing period.

     We will determine,  in our sole  discretion,  whether to establish a waiver
discount after a review of current market conditions, the level of participation
and our current and projected capital needs. At least three business days before
the first day of the applicable  pricing  period,  we will determine  whether to
establish a waiver  discount  and,  if a waiver  discount  is  established,  its
amount,  and  will  notify  the  plan  administrator.  Neither  we nor the  plan
administrator  will be  required  to provide  any  written  notice of the waiver
discount, if any, for any pricing period. We also reserve the right to establish
a reverse auction procedure by which participants  seeking to make optional cash
investments under a waiver may submit to us a "bid" with respect to the discount
at which they are willing to make the optional cash investment. Participants may
ascertain  whether we have  established  a waiver  discount,  the amount of such
discount and whether we have  established  a reverse  auction  procedure for any
pricing  period by telephoning  Investor  Relations at (617) 535-4799 or at such
other number as we may establish  from time to time, as is explained in Question
17.

19.  IN WHAT SITUATIONS WILL AN INVESTMENT BE RETURNED TO A PARTICIPANT?

     The plan  administrator will return optional cash investments of $10,000 or
less to a participant provided the plan administrator receives a written request
at  least  two  business  days  prior  to the  investment  date.  Optional  cash
investments of $10,000 or less will be returned by check,  without interest,  as
soon as  reasonably  practicable.  Please note that  optional  cash  investments
greater than $10,000 for which a  participant  has received an approved  request
for waiver will not be returned to a  participant,  except for as  described  in
Question 18 under  "--Threshold  Price With Respect to Optional Cash Investments
Made Pursuant to Requests for Waiver."  Question 12 further provides for returns
of optional and initial cash  investments if such  investments are not invested,
for whatever reason, within 35 days of receipt of funds. Additionally,  Question
12 provides that cash dividends will be disbursed if not invested within 30 days
after the dividend payment date.

20.  WHAT IF A PARTICIPANT HAS MORE THAN ONE ACCOUNT IN THE PLAN?

     For the purpose of the limitations discussed in this prospectus, we reserve
the right to aggregate all optional  investments for participants with more than
one  account  using the same  name,  address  or  social  security  or  taxpayer
identification  number.  For participants  unable to supply a social security or
taxpayer  identification number,  participation may be limited by us to only one
plan account.  Also for the purpose of such limitations,  all plan accounts that
we believe to be under common  control or management or to have common  ultimate
beneficial  ownership may be  aggregated.  In the event we exercise our right to
aggregate investments and the result would be an investment in excess of $10,000
without an approved request for waiver,  we will return,  without  interest,  as
promptly as practicable, any amounts in excess of the investment limitations.


                                      -13-


21.  WILL  CERTIFICATES BE ISSUED TO  PARTICIPANTS  FOR THE SHARES OF OUR COMMON
     STOCK PURCHASED UNDER THE PLAN?

     All shares purchased pursuant to the plan will be held in "book entry" form
through accounts  maintained by the plan  administrator.  This serves to protect
against  the loss,  theft or  destruction  of  certificates  evidencing  shares.
Participants  may contact  the plan  administrator  at the address or  telephone
number set forth in Question 5 above,  or may utilize  the cash  investment  and
other transaction form attached to the bottom of each statement of holdings,  to
request  a  certificate  for  all or a  portion  of the  whole  shares  held  in
book-entry form. Upon such a request,  the plan  administrator  will, within two
business  days of receipt of the request,  issue and mail  certificates  for the
whole shares credited to that participant's account. Certificates will be issued
only in the  same  names  as  those  enrolled  in the  plan.  In no  event  will
certificates for fractional shares be issued.

     If a  participant  requests a  certificate  for whole  shares of our common
stock held in his or her account, distributions on those shares will continue to
be reinvested or paid in cash, as elected by the participant,  under the plan in
the same  manner as prior to the  request so long as the shares of common  stock
remain registered in the participant's name.

22.  MAY A  PARTICIPANT  DEPOSIT WITH THE PLAN  ADMINISTRATOR  CERTIFICATES  FOR
     SHARES WHICH HE OR SHE ALREADY OWNS OUTSIDE THE PLAN?

     Yes, if the certificates are  unrestricted.  Whether or not the participant
has previously authorized reinvestment of dividends,  certificates registered in
the participant's name that do not bear any legend  restricting  transfer may be
surrendered  to the plan  administrator  for deposit in the  participant's  plan
account.  If a  participant  desires to deposit  certificates  for shares of our
common stock with the plan  administrator,  the participant may contact the plan
administrator  at the address or telephone  number  listed in Question 5 for the
proper procedure.

23.  CAN PARTICIPANTS SELL SHARES HELD UNDER THE PLAN?

     Participants  may  contact the plan  administrator  in order to request the
sale of all or a portion of the shares  held in their  plan  account.  Following
receipt of instructions  from a participant,  the plan  administrator  will sell
those shares as soon as  practicable  and will remit a check for the proceeds of
such  sale,  less a service  fee equal  $15.00,  brokerage  commissions  and any
applicable taxes.

     Shares  to be  sold  will  be  aggregated  by the  plan  administrator  and
generally  sold within  five  business  days.  The sales price per share will be
equal to the weighted  average price of all shares sold on the trading day, less
brokerage commissions, which are currently equal to $0.12 per share.

     All sale request having an anticipated market value of $100,000.00 or more,
and all sale requests  received by the plan  administrator  within 30 days of an
address  change to a  participant's  plan account,  must be submitted in written
form to the plan administrator.

     Please note that the plan administrator is not able to accept  instructions
to sell on a particular date or at a specific price.

24.  CAN A PARTICIPANT TRANSFER SHARES HELD IN THE PLAN TO SOMEONE ELSE?

     Participants may transfer  ownership of a portion or all of the shares held
in their plan accounts.  Participants  should contact the plan  administrator at
the  address or  telephone  number  listed in Question 5 for  detailed  transfer
instructions.

25.  WHAT  HAPPENS  IF A  PARTICIPANT  SELLS OR  TRANSFERS  SHARES  OR  ACQUIRES
     ADDITIONAL SHARES?

     If a participant has elected to have dividends automatically  reinvested in
the  plan and  subsequently  sells or  transfers  all or any part of the  shares
registered in the participant's  name,  automatic  reinvestment will continue in
accordance with the participant's  instructions as long as shares are registered
in the  name  of the  participant  or  held  for  the  participant  by the  plan
administrator or until termination of participation or the participant specifies
otherwise.   Similarly,   if  a  participant  has  elected  the  "Full  Dividend
Reinvestment" option under the plan and subsequently  acquires additional shares
registered  in the  participant's  name,  dividends  paid  on such  shares  will
automatically   be  reinvested   until   termination  of  participation  or  the
participant  specifies  otherwise.  If,  however,  a

                                      -14-


participant  has  elected  the  "Partial  Dividend   Reinvestment"   option  and
subsequently acquires additional shares that are registered in the participant's
name, dividends will be reinvested  according to the participant's  instructions
as given on the most recent  shareholder  authorization  form.  Participants may
change their  dividend  reinvestment  elections by submitting a new  shareholder
authorization form or by contacting the plan  administrator.  However, we remind
you that it is unlikely we will pay cash dividends in the foreseeable future.

26.  WHAT REPORTS ARE SENT TO PARTICIPANTS?

     After any activity  occurs relating to a  participant's  plan account,  the
participant  will be sent a statement of holdings  that will provide a record of
the costs of the shares of our common stock purchased or the price of the shares
sold for that  account,  the  purchase  or sale date and the number of shares of
common stock then credited to that account.  We recommend  that you retain these
statements for income tax and general record keeping purposes.

     In addition,  each  participant  will be sent our annual report,  notice of
annual meeting and proxy  statement,  and income tax  information  for reporting
distributions received. All reports and notices from the plan administrator will
be addressed to the participant's last known address. Participants should notify
the plan administrator promptly of any change of address.

27.  MAY A PARTICIPANT TERMINATE HIS OR HER PLAN ACCOUNT?

     Yes, a participant  may terminate his or her plan account by contacting the
plan administrator at the address or telephone number listed in Question 5 or by
utilizing  the cash  investment  and other  transaction  form  attached  to each
statement of holdings.  Participation  will be terminated as soon as practicable
provided the request is received at least two business days prior to the payable
date for a dividend  payment.  If the request is received less than two business
days prior to the payable date for a dividend  payment,  the  termination may be
postponed until after the  reinvestment of any dividends on the dividend payment
date.  After  that time all cash  dividends,  if any,  on  shares  owned by such
participant will be sent to the participant.

     If a  participant's  plan account  balance falls below one full share,  the
plan  administrator  reserves the right to liquidate  the fraction and remit the
proceeds, less any applicable fees and brokerage commissions, to the participant
at its address of record.

28.  WHAT HAPPENS WHEN A PARTICIPANT TERMINATES AN ACCOUNT?

     As soon as practicable  after notice of  termination is received,  the plan
administrator  will send to the  participant  (1) a certificate  evidencing  all
whole  shares  of  our  common  stock  held  in  the  account  and  (2) a  check
representing the value of any fractional  shares of our common stock held in the
account, less any brokerage commission.  After an account is terminated, we will
pay all distributions for the terminated  account to the participant  unless the
participant re-elects to participate in the plan.

     When terminating an account, the participant may request that all shares of
our common stock,  both whole and fractional,  held in the plan account be sold,
or that certain of the shares of such common stock be sold and a certificate  be
issued for the remaining whole shares.  The plan administrator will remit to the
participant  the  proceeds of any sale of shares of our common  stock,  less the
fees and  commissions  listed in  Questions  10 and 23. The sale price per share
will be equal to the  weighted  average  price of all shares sold on the trading
day, less brokerage commissions, which are currently $0.12 per share.

29.  WHEN MAY A FORMER PARTICIPANT RE-ELECT TO PARTICIPATE IN THE PLAN?

     Generally,  any former participant may re-elect to participate at any time.
However,  the plan administrator  reserves the right to reject any authorization
form on the grounds of excessive  joining and  withdrawing.  This reservation is
intended to minimize unnecessary  administrative expense and to encourage use of
the plan as a long-term investment service.

30.  WHAT ARE THE FEDERAL INCOME TAX CONSEQUENCES OF PARTICIPATING IN THE PLAN?

     The  federal   income  tax   consequences   resulting  from  optional  cash
investments are uncertain.  Participants may be deemed to receive a distribution
from us upon the  purchase of shares  pursuant to the plan in an amount equal to
the  excess,  if any,  of the fair  market  value of the shares  acquired on the
investment  date plus the  participant's  share of any fees paid by us, over the
purchase  price for the shares.  The fair market value of shares  acquired on an

                                      -15-


investment  date is not  likely  to differ  from the  amount  of  optional  cash
investment by  participants  making  investments  not  exceeding  $10,000 in any
single month.  Participants  making  investments  exceeding  $10,000 in a single
month who are  eligible  for a discount  may be more likely to have a difference
between the fair market value of shares  acquired on an investment  date and the
amount of optional cash investment.

     Any such deemed  distribution  will be treated as a taxable dividend to the
extent attributable to our current or accumulated  earnings and profits and then
only if other  shareholders  receive or are deemed to receive  distributions  of
cash or other  property  from us. If the  deemed  distribution  is  taxable as a
dividend, the shares purchased under the plan will have a tax basis equal to the
amount  of  the  optional  cash   investment  plus  the  amount  of  the  deemed
distribution,  if any,  which is  treated as a taxable  dividend.  If the deemed
distribution  is  not  treated  as  a  taxable  dividend,  the  effect  of  such
distribution  on a  shareholder's  basis  in his  shares  is  uncertain.  If the
distribution  is  treated as made  solely  with  respect  to the newly  acquired
shares,  or if the shareholder  does not own other shares of our common stock at
the time of the  optional  cash  investment,  the basis of such  newly  acquired
shares will  generally  equal the amount paid for such shares.  However,  if the
distribution  is treated as made with respect to both the newly acquired  shares
(or  fraction  thereof)  and the other  shares of our common  stock held by such
shareholder,  the basis of the newly acquired  shares (or fraction  thereof) may
exceed the amount  paid for such  shares and the basis for the shares held prior
to the optional  investment would be correspondingly  reduced. In any event, the
aggregate  bases for all of a  shareholder's  shares of our common stock will be
equal to the  aggregate  bases for the shares  previously  owned plus the amount
paid for the newly  acquired  shares.  Finally,  it is unclear as to whether any
gain or loss  realized  with  respect to a deemed  nondividend  distribution  in
excess  of  stock  basis  would  be  calculated  on a  per-share  basis or on an
aggregate  basis  for all of the  holder's  shares,  including  the  shares,  or
fraction thereof, purchased under the plan.

     As to reinvested dividends, participants will be treated as having received
a distribution  from us equal to the fair market value on the investment date of
the shares, if any, acquired with reinvested dividends pursuant to the plan plus
the  participant's  share  of any fees  paid by us.  Such  distribution  will be
treated as a taxable  dividend  to the  extent  attributable  to our  current or
accumulated  earnings and profits.  If we do not have earnings and profits,  any
excess  will  first be  treated  as a  tax-free  return  of  capital,  causing a
reduction  in the basis of existing  shares,  and the balance will be treated as
capital gain recognized on a sale or exchange.  A participant's tax basis in the
distributed  shares  will  equal  the fair  market  value of such  shares on the
investment date plus the participant's share of any fees paid by us.

     A  participant's  holding period for shares  acquired  pursuant to the plan
will begin on the day following the date on which the shares are credited to the
participant's account. When a participant receives certificates for whole shares
credited to the  participant's  account under the plan, the participant will not
realize  any  taxable  income.  However,  a  participant  that  receives  a cash
adjustment for a fraction of a share will realize a gain or loss with respect to
such fraction.  A gain or loss also will be realized by the participant whenever
whole  shares are sold,  either  pursuant  to the  participant's  request,  upon
withdrawal  from the plan or after  withdrawal from the plan. The amount of such
gain or loss will be the  difference  between  the amount  that the  participant
receives  for the  shares  or  fraction  of a share  and  the tax  basis  of the
participant in the shares.

     THE FOREGOING IS ONLY A SUMMARY OF THE FEDERAL INCOME TAX  CONSEQUENCES  OF
PARTICIPATION  IN THE PLAN AND DOES NOT CONSTITUTE  TAX ADVICE.  THIS SUMMARY IS
BASED ON THE  CURRENT  STATE OF  FEDERAL  LAW AND  DOES  NOT TAKE  INTO  ACCOUNT
POSSIBLE CHANGES IN SUCH LAW. ANY SUCH CHANGES MAY HAVE  RETROACTIVE  EFFECT AND
MAY  ADVERSELY  AFFECT THE  DISCUSSION  IN THIS  SUMMARY.  THIS SUMMARY DOES NOT
ADDRESS  THE  SPECIAL  TAX  CONSEQUENCES  THAT  MAY  BE  APPLICABLE  TO  CERTAIN
PARTICIPANTS   SUBJECT   TO  SPECIAL   TAX   TREATMENT   (INCLUDING   TAX-EXEMPT
ORGANIZATIONS, BROKERS, DEALERS AND FOREIGN SHAREHOLDERS). THIS SUMMARY DOES NOT
REFLECT EVERY POSSIBLE OUTCOME THAT COULD RESULT FROM  PARTICIPATION IN THE PLAN
AND,  THEREFORE,  PARTICIPANTS ARE ADVISED TO CONSULT THEIR OWN TAX ADVISORS FOR
FURTHER  INFORMATION WITH RESPECT TO THE FEDERAL,  FOREIGN,  STATE AND LOCAL TAX
CONSEQUENCES OF PARTICIPATION IN THE PLAN.

31.  HOW ARE THE  PARTICIPANT'S  SHARES OF  COMMON  STOCK  VOTED AT  SHAREHOLDER
     MEETINGS?

     The plan administrator will send participants proxy materials,  including a
proxy card,  relating to both the shares for which  participants  hold  physical
certificates  and the  whole  shares  of our  common  stock  held in their  plan
accounts.  Shares  will be voted at  shareholder  meetings  as that  participant
directs by proxy.  Shares of our common stock may also be voted in person at the

32.  WHAT IS THE  RESPONSIBILITY  OF IRON  MOUNTAIN  AND THE PLAN  ADMINISTRATOR
     UNDER THE PLAN?

     We and the plan  administrator,  in administering  the plan, are not liable
for any act done in good faith or for any good faith omission to act, including,
without limitation, any claim of liability:

     o    with  respect to the  prices  and times at which  shares of our common
          stock are purchased or sold for a participant; or

     o    with  respect to any  fluctuation  in market value before or after any
          purchase or sale of shares of our common stock; or

     o    arising out of any failure to terminate a  participant's  account upon
          that participant's death prior to the plan administrator's  receipt of
          notice in writing of the death.

Neither we nor the plan  administrator can provide any assurance of a profit, or
protect a participant from a loss, on shares of our common stock purchased under
the plan. These  limitations of liability do not affect any liabilities  arising
under the federal securities laws, including the Securities Act.

     The plan  administrator may resign as plan administrator of the plan at any
time, in which case we will appoint a successor plan administrator. In addition,
we may replace the plan administrator with a successor plan administrator at any
time.

33.  WHAT HAPPENS IF WE MAKE A  DISTRIBUTION  OF SHARES OF COMMON STOCK OR SPLIT
     OUR SHARES?

     If there is a  distribution  payable  in  shares of our  common  stock or a
common  stock  split,  the plan  administrator  will  receive  and credit to the
participant's  plan account the  applicable  number of whole  and/or  fractional
shares of common stock based on the number of shares of common stock held in the
participant's  plan account and  registered  in the  participant's  name.  If we
effect a reverse  stock split,  the number of shares held in each  participant's
plan account will be proportionately reduced.

34.  WHAT HAPPENS IF WE HAVE A RIGHTS OFFERING?

     If we have a rights offering in which  separately  tradable and exercisable
rights are issued to registered  holders of shares of our common stock,  we will
transfer the rights  attributable  to whole shares of our common stock held in a
participant's  plan account and registered in the participant's name to the plan
participant as promptly as practicable after the rights are issued.

35.  MAY A  PARTICIPANT  PLEDGE  SHARES OF COMMON  STOCK HELD IN HIS OR HER PLAN
     ACCOUNT?

     A participant  may not pledge shares of our common stock held in his or her
plan account,  and any such  purported  pledge will be void. A  participant  who
wishes to pledge shares of our common stock must request that a certificate  for
those shares first be issued in the  participant's  name or that these shares be
transferred to a brokerage account.

36.  MAY WE SUSPEND OR TERMINATE THE PLAN?

     We may  suspend  or  terminate  the  plan at any  time.  If we  suspend  or
terminate the plan, all funds held by us for investment will be returned without
interest.  We also  reserve the right to modify,  suspend,  terminate  or refuse
participation in the plan to any person at any time.

37.  MAY WE AMEND THE PLAN?

     We may  amend  or  supplement  the  plan  at any  time.  Any  amendment  or
supplement  will only be effective  upon mailing  appropriate  written notice at
least 30 days prior to the effective date thereof to each  participant.  Written
notice  is not  required  when  an  amendment  or  supplement  is  necessary  or
appropriate  to comply with the rules or policies of the Securities and Exchange
Commission,  the Internal Revenue Service or other regulatory  authority or law,
or when an  amendment or  supplement  does not  materially  affect the rights of
participants.  The  amendment or

                                      -17-


supplement will be deemed to be accepted by a participant  unless,  prior to the
effective  date  thereof,   the  plan  administrator   receives  notice  of  the
termination  of a  participant's  plan  account.  Any  amendment  may include an
appointment by the plan  administrator or by us of a successor bank or agent, in
which  event we are  authorized  to pay  that  successor  bank or agent  for the
account of the  participant  all  distributions  payable on shares of our common
stock held by the participant for application by that successor bank or agent as
provided in the plan.

38.  WHAT HAPPENS IF WE TERMINATE THE PLAN?

     If the plan is terminated,  each participant will receive (1) a certificate
for all whole shares of our common stock held in the participant's  plan account
and (2) a check  representing  the value of any fractional  shares of our common
stock held in the participant's plan account, less any brokerage commissions and
any uninvested distributions held in the account.

39.  WHO INTERPRETS AND REGULATES THE PLAN?

     We are authorized to issue such interpretations, adopt such regulations and
take such action as we may deem reasonably necessary to effectuate the plan. Any
action  we or the plan  administrator  take to  effectuate  the plan in the good
faith exercise of our judgment will be binding on participants.

                                 USE OF PROCEEDS

     Unless otherwise described in a prospectus supplement, we intend to use the
net proceeds from the sale of our common stock offered  pursuant to the plan for
general corporate purposes, which may include acquisitions,  investments and the
repayment  of  indebtedness  outstanding  at a  particular  time.  Pending  this
utilization,  the proceeds from the sale of our common stock offered pursuant to
the plan will be invested in  short-term,  dividend-paying  or  interest-bearing
investment grade securities.

                              PLAN OF DISTRIBUTION

     Subject  to the  discussion  below,  we will  distribute  newly  issued  or
treasury shares of our common stock sold under the plan,  rather than through an
underwriter,  broker or dealer. There are no brokerage commissions in connection
with the purchases of such newly issued or treasury shares of common stock.

     In connection with the  administration  of the plan, we may be requested to
approve  investments  made  pursuant to  requests  for waiver by or on behalf of
participants or other investors who may be engaged in the securities business.

     Persons who acquire shares of common stock through the plan and resell them
shortly after  acquiring  them,  including  coverage of short  positions,  under
certain circumstances, may be participating in a distribution of securities that
would require compliance with Regulation M under the Securities  Exchange Act of
1934  and  may be  considered  to be  underwriters  within  the  meaning  of the
Securities  Act of 1933.  We will not  extend to any such  person  any rights or
privileges other than those to which it would be entitled as a participant,  nor
will we enter into any  agreement  with any such person  regarding the resale or
distribution  by any such person of the shares of our common stock so purchased.
We may, however, accept investments made pursuant to requests for waiver by such
persons.

     From time to time, financial intermediaries, including brokers and dealers,
and other  persons may engage in  positioning  transactions  in order to benefit
from any waiver  discounts  applicable to investments  made pursuant to requests
for waiver under the plan.  Those  transactions  may cause  fluctuations  in the
trading  volume of our common  stock.  Financial  intermediaries  and such other
persons who engage in positioning transactions may be deemed to be underwriters.
We have no arrangements or understandings,  formal or informal,  with any person
relating  to the sale of shares of our  common  stock to be  received  under the
plan. We reserve the right to modify, suspend or terminate  participation in the
plan by otherwise eligible persons to eliminate  practices that are inconsistent
with the purpose of the plan.

     We will pay any and all brokerage commissions and related expenses incurred
in connection with purchases of our common stock under the plan. Upon withdrawal
by a  participant  from the plan by the sale of shares of our common  stock held
under the plan,  the  participant  will receive the proceeds of that sale less a
service fee, brokerage commission and any applicable  withholdings,  transfer
or other taxes.

                                      -18-


     Our common stock may not be available under the plan in all states.  We are
not  making an offer to sell our  common  stock in any state  where the offer or
sale is not permitted.

                         SALES OF SHARES BY PARTICIPANTS

     Participants  that  request the sale of any of their shares of common stock
held in the plan must pay a service  fee  equal to $15.00,  plus a commission
currently  equal to $0.12 per share,  plus any applicable  taxes.  Shares of our
common stock may not be available under the plan in all states.  This prospectus
does not constitute an offer to sell, or a solicitation  of an offer to buy, any
shares  of our  common  stock  or other  securities  in any  state or any  other
jurisdiction  to any  person to whom it is  unlawful  to make such offer in such
jurisdiction.

                       VALIDITY OF THE OFFERED SECURITIES

     Sullivan  &  Worcester  LLP,  Boston,  Massachusetts,  will  pass  upon the
validity of the common stock offered pursuant to this prospectus.  As to certain
matters of Pennsylvania  law, Sullivan & Worcester LLP will rely upon an opinion
of Ballard Spahr Andrews & Ingersoll, LLP, Philadelphia, Pennsylvania.

                      NOTICE REGARDING ARTHUR ANDERSEN LLP

        Effective  June 19, 2002, we dismissed  Arthur  Andersen LLP, our former
independent  auditor.  Our  audited  consolidated  financial  statements  as  of
December  31, 2001 and for the years ended  December  31, 2001 and 2000 that are
incorporated by reference in the registration statement of which this prospectus
forms a part were audited by Andersen as stated in their reports incorporated by
reference herein,  and have been so incorporated in reliance upon the reports of
such firm given upon their  authority  as experts in  auditing  and  accounting.
Andersen  has not  consented  to the  incorporation  by  reference  of its audit
reports in the registration statement of which this prospectus forms a part, and
we have dispensed with the requirement to file Andersen's consent in reliance on
Rule 437a under the  Securities  Act.  Since  Andersen has not  consented to the
incorporation by reference of their audit reports in the registration statement,
an investor's ability to seek potential  recoveries from Andersen related to any
claims that an investor may assert as a result of the work performed by Andersen
may be limited  significantly  by the lack of such  consent  and the  diminished
amount of assets of Andersen  that are or may be  available  to satisfy any such
claims.

                                     EXPERTS

     The consolidated financial statements as of and for the year ended December
31, 2002  incorporated  in this  prospectus by reference  from the Iron Mountain
Incorporated  Annual  Report on Form 10-K for the year ended  December  31, 2002

application of procedures relating to certain disclosures and  reclassifications
of financial statement amounts related to the 2001 and 2000 financial statements
that  were  audited  by other  auditors  who have  ceased  operations)  which is
incorporated  by reference  and have been so  incorporated  in reliance upon the
report of such firm given their authority as experts in accounting and auditing.

     The report dated  February 21, 2003 of RSM Robson Rhodes,  the  independent
auditors,  on the  consolidated  financial  statements of Iron  Mountain  Europe

     On May 3, 2003,  RSM Robson Rhodes  transferred  its business to RSM Robson
Rhodes  LLP  (a  Limited  Liability  Partnership  under  the  Limited  Liability
Partnerships  Act 2000).  Under the powers given by Paragraph 3 of Section 26 of
the Companies Act 1989,  the Board of Directors of Iron Mountain  Europe Limited
resolved that the previous  appointment  of RSM Robson Rhodes as the auditors of
Iron Mountain  Europe Limited should be extended,  with effect from May 3, 2003,
to RSM Robson Rhodes LLP.

       The consolidated  financial statements of Iron Mountain  Incorporated and
its  subsidiaries  as of December 31, 2001 and for the years ended  December 31,
2001 and 2000, and its supplemental schedule, Valuation and Qualifying Accounts,
included in its Annual Report on Form 10-K for the year ended December 31, 2002,
filed  with  the  Securities  and  Exchange  Commission  on March  21,  2003 and
incorporated  by  reference  into  the  registration  statement  of  which  this
prospectus  forms a part, have been audited by Arthur Andersen LLP,  independent
public accountants, as set forth in their report dated February 22, 2002 (except
with  respect  to Note 17,  as to which the date

                                      -19-


is March 15, 2002).  In their report on Iron Mountain's  consolidated  financial
statements,  that firm states that,  with respect to certain  subsidiaries,  its

accountants.  The  consolidated  financial  statements and  supporting  schedule

Item 15. Indemnification of Directors and Officers

     Subchapter D (Sections 1741 through 1750) of Chapter 17 of the Pennsylvania
Business  Corporation Law of 1988, as amended (the "PBCL"),  contains provisions
for mandatory and discretionary  indemnification  of a corporation's  directors,
officers,  employees  and agents  (collectively  "Representatives")  and related
matters.

     Under Section 1741, subject to certain  limitations,  a corporation has the
power to indemnify directors,  officers and other  Representatives under certain
prescribed   circumstances   against  expenses   (including   attorneys'  fees),
judgments, fines and amounts paid in settlement actually and reasonably incurred
in connection  with a  threatened,  pending or completed  action or  proceeding,
whether civil, criminal,  administrative or investigative,  to which any of them
is a party  or  threatened  to be made  party  by  reason  of he or she  being a
Representative  of the  corporation or serving at the request of the corporation
as a Representative of another corporation, partnership, joint venture, trust or
other  enterprise,  if he or she  acted in good  faith and in a manner he or she
reasonably  believed  to be in, or not  opposed  to, the best  interests  of the
corporation  and,  with respect to any criminal  proceeding,  had no  reasonable
cause to believe his or her conduct was unlawful.  The termination of any action
or proceeding by judgment, order or settlement or conviction upon a plea of nolo
contendere shall not itself create a presumption that the Representative did not
act in good faith and in a manner he or she reasonably believes to be in, or not
opposed  to, the best  interests  of the  corporation,  and with  respect to any
criminal proceeding, has reasonable cause to believe that his or her conduct was
unlawful.

     Section 1742 provides for  indemnification  with respect to derivative  and
corporate   actions   similar  to  that  provided  by  Section  1741.   However,
indemnification  is not  provided  under  Section  1742 in respect of any claim,
issue or matter as to which a  Representative  has been adjudged to be liable to
the corporation  unless and only to the extent that the proper court  determines
upon application that,  despite the adjudication of liability but in view of all
the  circumstances  of the  case,  a  Representative  is fairly  and  reasonably
entitled to indemnity for the expenses that the court deems proper.

     Section 1743 provides that  indemnification  against expenses  actually and
reasonably  incurred is mandatory to the extent that a  Representative  has been
successful  on the  merits  or  otherwise  in  defense  of any  such  action  or
proceeding referred to in Section 1741 or 1742.

     Section 1744 provides that unless ordered by a court,  any  indemnification
under Section 1741 or 1742 shall be made by the corporation as authorized in the
specific case upon a determination  that  indemnification of a Representative is
proper because the  Representative met the applicable  standard of conduct,  and
such  determination will be made by the board of directors by a majority vote of
a quorum of directors  not parties to the action or

                                      II-1


proceeding;  if a quorum is not  obtainable or is obtainable and a majority vote
of disinterested directors so directs, by independent legal counsel in a written
opinion; or by the shareholders.

     Section  1745  provides  that  expenses  incurred  by a  Representative  in
defending any action or proceeding  referred to in Subchapter D of Chapter 17 of
the PBCL may be paid by the  corporation in advance of the final  disposition of
such action or proceeding upon receipt of any undertaking by or on behalf of the
Representative to repay such amount if it shall ultimately be determined that he
or she is not entitled to be indemnified by the corporation. Such advancement of
expenses shall be authorized by the board of directors.

     Section 1746 provides  generally that,  except in any case where the act or
failure to act giving rise to the claim for  indemnification  is determined by a
court   to  have   constituted   willful   misconduct   or   recklessness,   the
indemnification  and advancement of expenses provided by Subchapter D of Chapter
17 of the PBCL  shall not be  deemed  exclusive  of any other  rights to which a
Representative  seeking  indemnification  or  advancement  of  expenses  may  be
entitled  under any bylaw,  agreement,  vote of  shareholders  or  disinterested
directors or otherwise, both as to action in his or her official capacity and as
to action in another capacity while holding that office.

     Section  1747  grants a  corporation  the power to  purchase  and  maintain
insurance on behalf of any Representative  against any liability incurred by him
or her  in  his  or  her  capacity  as a  Representative,  whether  or  not  the
corporation  would have the power to indemnify him against that liability  under
Subchapter D of Chapter 17 of the PBCL.

     Section 1748 and 1749 apply the indemnification and advancement of expenses
provisions  contained  in  Subchapter  D of Chapter 17 of the PBCL to  successor
corporations resulting from consolidation,  merger or division and to service as
a representative of a corporation with respect to an employee benefit plan.

     Section 7.2 of the Company's bylaws provides  indemnification  to directors
and officers  for all actions  taken by them and for all failures to take action
to the fullest  extent  permitted  by  Pennsylvania  law  against  all  expense,
liability and loss reasonably  incurred by or imposed upon by them in connection
with any threatened, pending or completed action, suit or proceeding (including,
without  limitation,  an action,  suit or  proceeding  by or in the right of the
Company),  whether civil,  criminal,  administrative,  investigative  or through
arbitration.  Section 7.2 also  permits the  Company,  by action of its board of
directors, to indemnify officers, employees and other persons to the same extent
as directors.  Amendments,  repeals or  modifications of Section 7.2 can only be
prospective  and such changes require the unanimous vote of all of the directors
then  serving  or the  affirmative  vote of the  holders  of a  majority  of the
outstanding  shares of stock of the  Company  entitled to vote in  elections  of
directors. Section 7.2 further permits the Company to maintain insurance, at its
expense,  for the benefit of any person on behalf of whom insurance is permitted
to be  purchased by  Pennsylvania  law against any such  expenses,  liability or
loss,  whether or not the Company would have the power to indemnify  such person
against such expense, liability or loss under Pennsylvania or other law.

     Reference is made to the Underwriting  Agreements (Exhibits 1.1 through 1.8
hereto),  which  may  contain  certain  provisions  for  indemnification  by the
underwriters of the Company,  directors,  officers and controlling persons under
certain circumstances.

Item 17. Undertakings

(a) The undersigned registrants hereby undertake:

     (1)  To file,  during any period in which offers or sales are being made, a
          post-effective amendment to this registration statement:

               (i)  To include any  prospectus  required by Section  10(a)(3) of
                    the  Securities  Act of 1933,  as amended  (the  "Securities
                    Act");

               (ii) To reflect  in the  prospectus  any facts or events  arising
                    after the effective date of the  registration  statement (or
                    the most recent  post-effective  amendment  thereof)  which,
                    individually  or in the  aggregate,  represent a fundamental
                    change in the  information  set  forth in this  registration
                    statement.  Notwithstanding  the foregoing,  any increase or
                    decrease  in  volume  of  securities  offered  (if the total
                    dollar  value of  securities  offered  would not exceed that
                    which was registered) and any deviation from the low or high
                    end of the estimated maximum offering range may be reflected
                    in the form of  prospectus  filed with the SEC  pursuant  to
                    Rule 424(b) under the  Securities  Act if, in the aggregate,
                    the changes in volume and price  represent no more than a 20
                    percent change in the maximum  aggregate  offering price set
                    forth in the "Calculation of Registration  Fee" table in the
                    effective registration statement; and

               (iii)To include  any  material  information  with  respect to the
                    plan  of  distribution  not  previously  disclosed  in  this
                    registration  statement  or  any  material  change  to  such
                    information in this registration statement;

     provided, however, that subparagraphs (a)(1)(i) and (a)(1)(ii) do not apply
     if the information required to be included in a post-effective amendment by
     those  paragraphs  is  contained  in the  periodic  reports  filed  with or
     furnished  to the SEC by Iron  Mountain  pursuant  to Section 13 or Section
     15(d) of the  Securities  Exchange Act of 1934,  as amended (the  "Exchange
     Act"), that are incorporated by reference in this registration statement.

     (2)  That,  for  the  purpose  of  determining   any  liability  under  the
          Securities Act, each such post-effective  amendment shall be deemed to
          be a new  registration  statement  relating to the securities  offered
          therein,  and the  offering of such  securities  at that time shall be
          deemed to be the initial bona fide offering thereof.

     (3)  To remove from registration by means of a post-effective amendment any
          of  the  securities  being  registered  which  remain  unsold  at  the
          termination of the offering.

(b)  The undersigned registrants hereby further undertake that, for the purposes
     of determining any liability under the Securities Act, each filing of Iron
     Mountain's annual report pursuant to Section 13(a) or Section 15(d) of the
     Exchange Act (and, where applicable, each filing of an employee benefit
     plan's annual report pursuant to Section 15(d) of the Exchange Act) that is
     incorporated by reference in this registration statement shall be deemed to
     be a new registration statement relating to the securities offered therein,
     and the offering of such securities at that time shall be deemed to be the
     initial bona fide offering thereof.

(c)  Insofar as indemnification for liabilities arising under the Securities Act
     may be permitted to directors, officers and controlling persons of the
     registrants pursuant to the provisions described under Item 15 of this
     registration statement, or otherwise, the registrants have been advised
     that in the opinion of the SEC such indemnification is against public
     policy as expressed in the Securities Act and is, therefore, unenforceable.
     In the event that a claim for indemnification against such liabilities
     (other than the payment by the registrants of expenses incurred or paid by
     a director, officer or controlling person of the registrants in the
     successful defense of any action, suit or proceeding) is asserted by such
     director, officer or controlling person in connection with the securities
     being registered, the registrants will, unless in the opinion of their
     counsel the matter has been settled by controlling precedent, submit to a
     court of appropriate jurisdiction the question whether such indemnification
     by it is

                                      II-6


     against  public  policy  as  expressed  in the  Securities  Act and will be
     governed by the final adjudication of such issue.

(d)  The undersigned registrants hereby undertake that:

     (1)  For purposes of determining  any liability  under the Securities  Act,
          the information  omitted from the form of prospectus  filed as part of
          this  registration  statement in reliance upon Rule 430A and contained
          in a form of  prospectus  filed  by  Iron  Mountain  pursuant  to Rule
          424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to
          be part of this registration  statement as of the time it was declared
          effective;

     (2)  For purposes of determining  any liability  under the Securities  Act,
          each post-effective amendment that contains a form of prospectus shall
          be  deemed  to  be  a  new  registration  statement  relating  to  the
          securities  offered  therein,  and the offering of such  securities at
          that  time  shall be  deemed  to be the  initial  bona  fide  offering
          thereof.

(e)  The undersigned registrants hereby undertake to file an application for the
     purpose  of  determining  the  eligibility  of each  trustee  to act  under
     subsection  (a) of  Section  310 of the  Trust  Indenture  Act of 1939,  as
     amended  (the  "Act"),   in  accordance  with  the  rules  and  regulations
     prescribed by the SEC under Section 305(b)(2) of the Act.


                                      II-7


                                   SIGNATURES
